[0080] To avoid confusion in term construction, the refrigerator
compartment door used in the detailed description of the present
disclosure denotes the pivotable door. However, it is noted that a
refrigerator compartment door noted in claims includes the
pivotable door as well as the slidable door for opening and closing
the storage room used as the refrigerator compartment.
[0081] The storage room 100 is partitioned into an upper portion
and a lower portion by a partition. That is, the storage room 100
may be divided into a first storage room 100 above and a second
storage room 120 below. A first door 130 and a second door 140 are
withdrawably provided at the first storage room 110 and the second
storage room 120, respectively. If necessary, one storage room 100
may be provided, or two or more storage rooms 100 may be
provided.
[0082] The first door 130 is withdrawably installed in the storage
room 100. The first door 130 may be completely inserted to
completely cover the first storage room 110. A receiving part 134
extending backwardly is disposed in a back surface of the first
door 130.
[0083] The receiving part 134 may have a shape similar to that of a

the interior of the ice making compartment 160 may be thermally
insulated from the second storage room 120. That is, the second
storage room 120 may be thermally isolated from the ice making
compartment 160 by a separate insulation structure. On the other
hand, when the second storage room 120 is maintained at a
temperature corresponding to that of the freezer compartment,
transfer devices as well as the ice maker 162 may be received
within the second storage room 120 without requiring a separate
insulation or isolation structure.
[0090] The ice making compartment 160 may be integrally formed with
the back surface of the second door 140, and thus, may be
integrally withdrawn together with the second door 140.
[0091] At least portion of the ice making compartment may be
selectively opened and closed to allow the ice maker 162 within the
ice making compartment to be easily repaired and managed.
[0092] The ice making compartment 160 may be defined in a
relatively lower region of the second door 140. A receiving part
146 for receiving foods may be disposed at a rear side of the
second door 140 corresponding to an upper region of the ice making
compartment 160. The receiving part 146 may have various

[0101] The second transfer device 174 may have a spiral or coil
shape to transfer the ice transferred by the first transfer device
172 to an upward direction. At this time, an upper end of the
second transfer device 174 may be located at a position higher than
that of the dispensing hole 144 of the dispenser 142.
[0102] The third transfer device 176 may be disposed at the upper
end of the second transfer device 174. The third transfer device
176 is horizontally disposed and has a spiral or coil shape. The
third transfer device 176 is rotated by the separate motor 178 to
transfer the ice transferred upwardly by the second transfer device
174 to a front direction, i.e., toward the dispensing hole 144. The
second transfer device 174 may be connected to the third transfer
device 176 using a medium to rotate by a single drive unit. A
damper D may be disposed in the dispensing hole 144 to selectively
cover the dispensing hole 144. That is, the ice may be selectively
dispensed by an operation of the damper D.
[0103] If necessary, the transfer device 170 may have a shape
different from the spiral or coil shape. A transfer passage 180
having a diameter somewhat greater than that of the transfer device
170 may be defined inside the ice making compartment 160 to
smoothly transfer the made ice along the transfer device 170.
[0104] The first storage room 110 and the second storage room 120
may be used as a refrigerator compartment or a freezer compartment.
The first storage room 110 and the second storage room 120 may be
used as the switching room that can be converted into the
refrigerator compartment or the freezer compartment by varying a
temperature as necessary. At this time, the ice making compartment
160 should be formed as a completely independent insulation space
within the second storage room 120.
[0105] Although not shown, an evaporator for generating cool air is
disposed at a rear side of the freezer compartment 20. The cool air
generated by the evaporator is supplied into the freezer
compartment 20, the refrigerator compartment 30, the storage room
100, and the ice making compartment 160 to cool the spaces,
respectively.
[0106] Specifically, when the second door 140 is closed, the cool
air duct for supplying the cool air may communicate with the ice
making compartment 160 to perform an ice making operation in the
ice maker 162 received within the ice making compartment 160.
[0107] Hereinafter, an operation of the refrigerator including the
above-described components will be described in detail with
reference to accompanying drawings.
[0108] To receive the foods into the refrigerator 1, the door is
opened to store the foods in the refrigerator 1, and then, the door
is closed again.
[0109] Specifically, in case of the first storage room 110, the
user grasps a door handle 132 of the first door 130 to slidingly
withdraw the first door 130, thereby to open the first storage room
110. Then, the foods may be received into the receiving part 134
disposed at a rear side of the first door 130. After the foods are
received, the first door 130 is inserted to close the first storage
room 110.
[0110] Similarly, in case of the second storage room 120, the user
draws a door handle 144 of the second door 140 to slidingly
withdraw the second door 140, thereby to open the second storage
room 120. When the second door 140 is withdrawn, the ice making
compartment 160 integrally formed with the second door 140 is
withdrawn together and is exposed to the outside. Also, the
receiving part 146 disposed above the ice making compartment 160 is
withdrawn together with the second door 140 and is exposed to the
outside.
[0111] In case where the dispenser 142 is not provided in the
second door 140, when the storage room 100 is opened, at least side
of the ice making compartment 160 may be opened to take the ice out
of the ice making compartment 160 in a state where the second door
140 is opened.
[0112] The water and cool air may be supplied into the second door
140 in a state where the second door 140 is completely inserted
into the second storage room 120. Thus, after the second door 140
is completely closed, the ice is made by the ice maker 162, and
then, the made ice is dropped downwardly.
[0113] The ice stored below the ice maker 162 is horizontally moved
by the first transfer device 172, and then, is vertically moved by
the second transfer device 174. Then, the ice is horizontally moved
by the third transfer device 176 to reach the dispensing hole 144
of the dispenser 142. Finally, the ice transferred into the
dispensing hole 144 is dispensed to the outside through a
manipulation of the dispenser 142.
[0114] For a service of the ice maker 162 or the transfer device
170, the second door 140 is withdrawn to expose the ice making
compartment 160 to the outside. In this state, the ice maker 162 or
the transfer device 170 may be repaired, for this, the ice maker
162 and the transfer device 170 may be detachably provided.
[0115] For receiving the foods into the receiving part 146 of the
second door 140, the second door 140 is withdrawn to expose the
receiving part 146 to the outside, and then, the foods are received
into the receiving part 146. At this time, the foods stored in the
receiving part 146 are stored in a refrigerated or frozen state
according to an internal temperature of the second storage room
120.
[0116] The refrigerator may be also applied to various embodiments
except for the previously described embodiment. Hereinafter, a
refrigerator according to another embodiment will be described.
Components having the same structure as those of the previously
described embodiment will be given by the same reference numerals,
and thus, detailed descriptions thereof will be omitted.
[0117] FIG. 4 is an opened-up view of a refrigerator according to
another embodiment, and FIG. 5 is a partial cross-sectional view of
a refrigerator according to another embodiment.
[0118] In the present embodiment, an ice making compartment is
integrally formed with a back surface of a door for opening and
closing a storage room.
[0119] Referring to FIGS. 4 and 5, a refrigerator 1 according to

dispense the ice or water without bending waist.
[0123] In detail, in case where the second storage room 120 is
maintained at a temperature corresponding to that of the freezer
compartment 20, the ice making assembly 250 may be installed
without being isolated by an insulation member. On the other hand,
in case where the second storage room 120 is maintained at a
temperature corresponding to that of the second storage room 120,
the ice making compartment may be formed in an independent isolated
space by a separate insulation wall structure within the second
storage compartment 120.
[0124] An ice suit 248 communicating the ice making compartment 260
with the dispenser 242 is disposed in a rear surface of the second
door 240 in which the dispenser 242 is disposed. The ice stored
inside the ice making compartment 260 may be supplied into the
dispenser 242 through the ice suit 248. The ice suit 248 may be
opened and closed by a users manipulation. A damper D may be
disposed in the ice suit 248 to selectively dispense the ice. The
damper D may be also provided in another embodiments disclosed

at a position spaced apart from the auger 258 to crush the ice, and
the electric motor 256 for rotating the auger 258 and the crusher
257.
[0126] In case where the second storage room 120 is maintained at a
temperature corresponding to that of the refrigerator compartment,
a cool air inlet 262 and a cool air outlet 264 are separately
formed. The cool air inlet 262 and the cool air outlet 264 may
communicate with a cool air duct 280 disposed inside the second
storage room 120 in a state where the second door 240 is completely
inserted.
[0127] The cool air duct 280 includes a supply duct 282 selectively
communicating with the cool air inlet 262 to supply cool air
generated by an evaporator into the ice making compartment 250 and
a return duct 284 selectively communicating with the cool air
outlet 264 to guide the cool air within the ice making compartment
260 toward the evaporator. A water tank 290 for storing water to be
supplied into the ice maker 252 and drinking water to be supplied
into the dispenser 242 may be disposed inside the second storage
room 120. The water tank 290 may be selectively connected to the
ice maker 252 and the dispenser 242 by a water supply passage
292.
[0128] The water tank 290 may be disposed inside the ice making
compartment 260. The water tank 290 may be directly connected to a
water supply source or may be directly filled by a user. When the
second door 240 is withdrawn forwardly, the water supply passage
292 may be separated at any position, and an opening/closing valve
V may be disposed at the separated position. That is, when the
second door 240 is opened, the opening/closing valve V is closed to
prevent water from being supplied into the dispenser 242. When the
second door 240 is completely closed, the opening/closing valve V
is opened to supply the water into the dispenser 242. A kind of
opening/closing valve V is not limited. The same opening/closing
valve V may be applicable to drawings indicated below, duplicated
descriptions will be omitted.
[0129] The refrigerator may be also applied to various embodiments
except for the previously described embodiment. Hereinafter, a
refrigerator according to further another embodiment will be
described. Components having the same structure as those of the
previously described embodiment will be given by the same reference
numerals, and thus, detailed descriptions thereof will be
omitted.
[0130] In the present embodiment, an ice maker is integrally formed
with a back surface of a door for opening and closing a storage
room.
[0131] FIG. 6 is a partial cross-sectional view of a refrigerator
according to another embodiment.
[0132] Referring to FIG. 6, a first storage room 110 and a second
storage room 120 are defined in a refrigerator body 10. The second
storage room 120 may be selectively covered by slidingly
withdrawing the second door 340.
[0133] A dispenser 340 for dispensing made ice at the outside is
disposed in a front surface of the second door 340. An ice maker
352 for making the ice is disposed on a back surface of the second
door 340.
[0134] The ice maker 352 is received into an ice making compartment
upper part 360 defined in the second door 340. The ice making
compartment upper part 360 is selectively connected to an ice
making compartment lower part 370, which will be described later,
to form an insulation space. The ice making compartment upper part
360 protrudes backwardly from an upper portion of a back surface of
the second door 340 to receive the ice maker 352.
[0135] An opening 362 is defined in a bottom surface of the ice
making compartment upper part 360 to downwardly move ice made by
the ice maker 352. A cool air inlet 364 communicating with a supply
duct 282 disposed in the body 10 is defined in a rear surface of
ice making compartment upper part 360.
[0136] An ice bank 354 is disposed direct below the ice maker 352
in a state where the second door 340 is completely inserted. The
ice maker 354 is received into the ice making compartment lower
part 370 defined inside the second storage room 120. An auger 358
is operated by an electric motor 356 to guide the ice stored in the
ice bank 354 toward an ice suit 348. When a crusher 357 is operated
according to a user s selection, the ice is crushed at an inlet of
the ice suit 348 and is dispensed through the dispenser 342. A
region including the ice making compartment upper part 360 and the
ice making compartment lower part 370 is defined as an ice making
compartment. The ice making compartment constitutes a portion of
the second storage room 120. It may be construed that the ice
making compartment upper part 360 and the ice making compartment
lower part 370 denote structures that are independently formed for
partitioning the ice making compartment. That is, the ice maker 352
is received into the structure defining the ice making compartment
upper part 360, the ice bank 354 is received into the structure
defining the ice making compartment lower part 370. An ice making
assembly 350 include the ice maker 352, the ice bank 354, the
electric motor 356, the crusher 357, and the auger 358.
[0137] An opening 372 communicating with the opening 362 of the ice
making compartment upper part 360 when the second door 340 is
completely inserted is defined in a top surface of the ice making
compartment lower part 370. The opening 372 communicates with a
return duct 284 to circulate cool air into the ice making
compartment upper part 360 and the ice making compartment lower
part 370.
[0138] A water tank 390 is disposed at an upper side of the ice
making compartment lower part 370. A water supply passage 392 for
supplying ice making water and drinking water is selectively
connected to the water tank 390 when the second door 340 is
inserted. Thus, the ice making water and the drinking water may be
supplied into the ice maker 352 and the dispenser 342,
respectively, in a state where the second door 340 is closed.
[0139] In case where the second storage room 120 is maintained at a
temperature corresponding to that of the refrigerator compartment,
the ice making compartment upper part 360 and the ice making
compartment lower part 370 form a closed insulation space, i.e.,
one ice making compartment. On the other hand, in case where the
second storage room 120 is maintained at a temperature
corresponding to that of the freezer compartment, the ice making
compartment upper part 360 and the ice making compartment lower
part 370 need not be insulated and closed. That is, it may be
possible to install the ice maker 352 and the ice bank 354 in a
state where the ice making compartment upper part 360 and the ice
making compartment lower part 370 are not separately
partitioned.
[0140] A receiving part 346 for receiving foods is disposed at a
lower portion of a back surface of the second door 340. The
receiving part 346 is withdrawn together with the ice making
compartment upper part 360 when the second door 340 is withdrawn to
easily receive the foods. The receiving part 346 may have various
structures according to kinds of received foods.
[0141] FIG. 7 is a vertical cross-sectional view of a refrigerator
according to another embodiment.
[0142] Referring to FIG. 7, components of the present embodiment
have the same structure as those of FIG. 6, except that the ice
making compartment upper part 360 receiving the ice maker 352 is
fixed to an inner sidewall of the second storage room 120, and the
ice making compartment lower part 370 receiving the ice bank 354 is
fixed to the back surface of the second door 340. That is, when the
second door 340 is withdrawn, the ice making compartment lower part
370 is also withdrawn together with the second door 340, and
therefore, is separated from the ice making compartment upper part
360.
[0143] The water supply passage 392 directly connected to the water
supply source supplies the water into the ice maker 352. However,
it may be possible to install a separate water tank, like the
embodiment of FIG. 6. An opening/closing valve V is disposed at any
position of the water supply passage 392 extending toward the
dispenser 342 to dispense the drinking water. The opening/closing
valve V may be selectively closed according to an open or close
state of the second door 340.
[0144] The refrigerator may be also applied to various embodiments
except for the previously described embodiments. Hereinafter, a
refrigerator according to further another embodiment will be
described. Components having the same structure as those of the
previously described embodiment will be given by the same reference
numerals, and thus, detailed descriptions thereof will be
omitted.

making compartment 660. The receiving part 634 may be provided in
up-and-down two stages or one stage. The receiving part 634 may
have various structures according to types of foods.
[0174] For example, the receiving part 634 may have a structure
similar to a shelf or a rack structure or a basket shape. Also,
various structures such as a structure that is vertically
adjustable or a structure that is slidingly withdrawable in front
and rear directions may be applicable.
[0175] The second door 640 is disposed below the first door 630.
The second door 640 is slidingly withdrawable from the second
storage room 620. The second door 640 extends up to a length that
can cover a lower side of the second storage room 620 that is not
covered by the second door 640.
[0176] A receiving part 646 may be disposed on the back surface of
the second door 640. The receiving part 646 may be provided in one
stage or two stages according to a vertical length of the second
door 640.
[0177] A frame 622 extending horizontally may be disposed on a
front surface of the second storage room 620 corresponding to a
region in which a lower end of the first door 630 is in contact
with an upper end of the second door 640. The frame 622 may include
a barrier that is in contact with a gasket surrounding a back
surface of a lower end portion of the first door 630 and a back
surface of an upper end portion of the second door 640 to lock
tightly cool air.
[0178] Thus, it may prevent the cool air form leaking through a
portion at which the first door 630 is in contact with the second
door 640 even if the second storage room 620 is partitioned into
two spaces.
[0179] The refrigerator may be also applied to various embodiments
except for the previously described embodiments. Hereinafter, a
refrigerator according to further another embodiment will be
described. Components having the same structure as those of the
previously described embodiment will be given by the same reference
numerals, and thus, detailed descriptions thereof will be
omitted.
[0180] In the present embodiment, a plurality of storage rooms has
sizes different from each other, like the previously described
embodiment. However, it is different that each of doors has a size
in which only a corresponding storage room is opened and
closed.
[0181] FIG. 12 is a front perspective view of a refrigerator
according to another embodiment.
[0182] Referring to FIG. 12, a refrigerator 1 according to the
present embodiment includes a body 10 including a refrigerator
compartment 30, a freezer compartment 20, a first storage room 710,
and a second storage room 720, a refrigerator compartment door 32,
a freezer compartment door 22, a first door 730, and a second door
740. The refrigerator compartment door 32, the freezer compartment
door 22, the first door 730, and the second door 740 selectively
cover the refrigerator compartment 30, the freezer compartment 20,
the first storage room 710, and the second storage room 720,
respectively.
[0183] The first storage room 710 and the second storage room 720
may have vertical lengths different from each other. Also, the
first door 730 and the second door 740, which open and close the
first storage room 710 and the second storage room 720,
respectively, may have vertical lengths different from each other.
As described above, the first door 730 may have a size in which
only the first storage room 710 is opened and closed, and the
second door 740 may have a size in which only the second storage
room 720 is opened and closed.
[0184] In detail, the first storage room 710 is defined at a left
upper portion of the body 10 corresponding to a left side of the
refrigerator compartment 30. The first storage room 710 may be
maintained at a temperature corresponding to that of the
refrigerator compartment or the freezer compartment by cool air
supplied from an evaporator. The first storage room 710 may be
separated from the second storage room 720 by a partition.
[0185] The first storage room 710 may have a vertical length longer
than that of the second storage room 720. Thus, the first door 730
covering the first storage room 710 may have a vertical length
longer than that of the second door 740.
[0186] An ice making compartment 760 extending backwardly is
disposed on a back surface of the first door 730. An ice making
assembly 450 for making and storing ice is received into the ice
making compartment 760. The ice making compartment 760 may be
integrally formed with the back surface of the first door 730, and
thus, may be withdrawn together with the first door 730 when the
first door 730 is withdrawn.
[0187] When the first storage room 710 is maintained at a
temperature corresponding to that of the refrigerator compartment,
the ice making compartment 760 may form an independent insulation
space isolated from the first storage room 710. That is, the ice
making compartment 760 may form an independent space within the
first storage room 710 by a separate insulation wall structure. At
least portion of the ice making compartment 760 may be selectively
opened and closed by a user to easily service and clean the ice
making compartment 760.
[0188] A receiving part 754 may be disposed on a back surface of
the first door 730 corresponding to a lower region of the ice
making compartment 760. The receiving part 754 may be provided in
one stage or two stages according to a vertical length of the first
door 730. Also, the receiving part 754 may have various structures
to receive various foods.
[0189] A dispenser 736 for dispensing the ice supplied from the ice
making compartment 760 to the outside may be disposed in a front
surface of the first door 730. The dispenser 736 may be disposed
below the ice making compartment 760, and also may be disposed at a
position near to a lower end of the first door 730.
[0190] That is to say, the first door 730 may have a length in
which the user has access to the dispenser 736 to easily dispense
drinking water and the made ice.
[0191] The second storage room 720 may be disposed below the first
storage room 710. The second storage room 720 may have a vertical
length somewhat shorter than that of the first storage room 710.
The second storage room 720 may be maintained at a temperature
corresponding to that of the refrigerator compartment or the
freezer compartment. The second storage room 720 may be selectively
covered by the second door 740 that is slidingly withdrawn.
[0192] The second door 740 has a size corresponding to that of an
opened front surface of the second storage room 720. A receiving
part 744 for receiving foods may be disposed on a back surface of
the second door 740. Thus, when the second door 740 is opened, the
second storage room 720 may be opened also to expose the receiving
part 744 to the outside, thereby to receive the foods.
[0193] The receiving part 744 may have various structures according
to kinds of foods. The receiving part 744 may be provided in one
stage or two stages according to a vertical length of the second
door 740.
[0194] FIG. 13 is a front perspective view of a refrigerator
according to another embodiment, and FIG. 14 is a partial
cross-sectional view of a refrigerator according to the
embodiment.
[0195] In the present embodiment, a storage rooms is vertically
partitioned, and an ice making assembly is disposed in a space
different from a dispenser. Thus, the ice making assembly and the
dispenser are disposed on doors different from each other,
respectively.
[0196] Referring to FIGS. 13 and 14, a separate storage room for
receiving a drawer-type door is provided at a lateral surface of a
refrigerator compartment 30 of a refrigerator 1, and the storage
room is separated from the refrigerator compartment 30.
[0197] In detail, the storage room is partitioned into a first
storage room 710 and a second storage room 720 defined below the
first storage room 710 by a partition 190. The first storage room
710 is selectively covered by a first door 730, and the second
storage room 720 is selectively covered by a second door 740. An
ice making compartment is disposed on a back surface of the first
door 730, and an ice making assembly 450 is received into the ice
making compartment 460. As described above, the ice making assembly
450 includes a transfer unit including an ice maker 452, an ice
bank 454, an auger 458, and a crusher 457 and an electric motor 456
for operating the transfer unit.
[0198] In case where the first storage room 710 is used as a
freezer compartment, an insulation wall structure defining the ice
making compartment 710 may be not necessary. The second storage
room 720 may be converted into one of the refrigerator compartment
and the freezer compartment.
[0199] A supply duct 282 for supplying cool air and a return duct
284, by which the cool air supplied into the ice making compartment
460 or the first storage room 710 returns to an evaporator, extend
into a wall defining a body 10. A dispenser 742 for dispensing ice
stored in the ice bank 454 or drinking water is disposed in a front
surface of the second door 740. A receiving part 744 is disposed on
a back surface of the second door 740 corresponding to a rear side
of the dispenser 742. According to a design method, the dispenser
736 may have a structure for dispensing only the ice, and a
structure for dispensing the drinking water may be not provided. An
ice making assembly 450 and/or a water tank 290 for supplying water
into a drinking water dispensing hole disposed in the dispenser 742
are disposed inside the second storage room 720. Here, a water
supply passage 292 extends from the water tank 290. Since the first
door 730 and the second door 740 are slidingly withdrawn, the water
supply passage 292 may be detachably coupled to the water tank 290.
That is to say, when the first door 730 and/or the second door 740
are/is withdrawn in a front direction, the water supply passage 292
may be separated from the water tank 290. Also, when the first door
730 and/or the second door 740 are/is completely closed, the water
supply passage 292 may be variably connected to the water tank 290.
At this time, a sealing structure for preventing the water from
leaking through a portion connecting the water supply passage 292
to the water tank 290.
[0200] An ice suit 748 for discharging the ice stored in the ice
bank 454 toward the dispenser 742 is disposed in the back surface
of the second door 740. A discharge hole 461 for discharging the
ice is defined at a side of a bottom surface of the ice bank 454.
In case where the ice making assembly 450 is received into the ice
making compartment 450, the discharge hole 461 may be defined in at
least one bottom surface of insulation walls defining the ice
making compartment 460. A discharge duct 191 connecting the
discharge hole 461 to the ice suit 748 is disposed in the partition
190. A damper D may be disposed inside the discharge duct 191. A
distance between the ice making assembly 450 including the ice bank
454 and the ice suit 748 may be minimized to improve utilization of
inner spaces of the storage rooms 710 and 720. Thus, it is
advantageous that the ice making assembly 450 is disposed at a
position maximally near to a top surface of the partition 190, and
the ice suit 748 is disposed at a position maximally near to a
bottom surface of the partition 190. In case where the ice making
assembly 450 and the ice suit 748 are spaced a predetermined
distance from the partition 190, an inner space of the storage room
corresponding to the spaced distance may not receive foods. Thus,
it is advantageous that a bottom surface of the ice making assembly
450 or the ice making room 460 is near to the top surface of the
partition 190, and an upper end of the ice suit 748 is near to the
bottom surface of the partition 190. In this case, the dispenser
742 may be disposed at a position further near to an upper end of
the second door 740. Thus, a vertical length of the dispenser 742
may extends vertically so that a position of the bottom is not
changed. Therefore, a user having a small height such as a child
easily dispenses the ice and water through the dispenser 742.
[0201] Since the ice making compartment 460 including the ice
making assembly 450 is received into the first storage room 710,
and the dispenser 742 is received into the second storage room 720,
it may obtain the following effects. That is, the ice making
assembly 450 is hardly exposed to the outside of the refrigerator 1
except for a repair due to malfunction. Also, ice making efficiency
may be reduced when the ice making assembly 450 is frequently
exposed to the outside. Thus, to overcome the above-described
limitation, the ice making assembly 450 should be disposed in a
separate space within the first storage room 710. The dispenser 742
is disposed in the second door 740. When the second storage room
720 is maintained at a temperature corresponding to that of the
refrigerator compartment, it may prevent the water supply passage
292 and the water tank 290 from being frozen over.
[0202] Although a separate water storage container such as the
water tank 290 is disposed inside the refrigerator 1 in the present
embodiment, the present disclosure is not limited thereto. For
example, as shown in FIG. 6, the water supply passage may be
directly connected to a water supply source.
[0203] Also, in the present embodiment, a slight modification may
be applied to form the following structure. Although not shown, it
is obvious to those skilled in the art that the following structure
may be applicable to the present embodiment.
[0204] In detail, the second door 740 may be partitioned into a
dispenser region and other regions to form two doors. That is, the
second door 740 may be divided into two doors to cover the second
storage room 720 by the second door 720. For example, the
refrigerator 1 may include a first door covering the ice making
compartment 460 received into the first storage room 710, a second
door covering a portion of the second storage room 720 and
including the dispenser and the receiving part, and a third door
covering a portion of a lower side of the second storage room 720
and including only the receiving part.
[0205] FIG. 15 is a front perspective view of a refrigerator
according to another embodiment, and FIG. 16 is a partial
cross-sectional view of a refrigerator according to the
embodiment.
[0206] In the present embodiment, an ice making assembly is fixed
inside a storage room, and only a dispenser is disposed on a back
surface of the storage room and is withdrawn together with a
door.
[0207] Referring to FIGS. 15 and 16, in a refrigerator 1 according
to the present embodiment, a separate storage room is defined at a
lateral surface of a refrigerator compartment 30. The storage room
is partitioned into an upper region and a lower region by a
partition 190. An ice making assembly is fixed to one of the
partitioned storage rooms.
[0208] In detail, the storage room is partitioned into a first
storage room 710 and a second storage room 720, like the previously
described embodiment. The first storage room 710 and the second
storage room 720 are selectively covered by a first door 730 and a
second door 740, respectively. The first door 730 and the second
door 740 are provided in a drawer-type. An ice making assembly 450
is fixed inside the first storage room 710, and a dispenser 736 is
disposed on a back surface of the second door 740. Hereinafter,
components having the same structure as those of FIGS. 13 and 14
will be given by the same reference numerals.
[0209] In detail, an opened front surface of the first storage room
710 may be covered by an insulation wall 711. The first storage
room 710 may be maintained at a temperature corresponding to that
of a freezer compartment 20. An ice making assembly 450 is fixed
inside the first storage room 710. As described above, the ice
making assembly 450 may include an ice maker 452, an ice bank 454,
an electric motor 456, a crusher 457, and an auger 458. The ice
making assembly 450 may further include a cooling fan 459 according
to a design condition. The cooling fan 459 uniformly distributes
cool air supplied from a supply duct 282 to the inside of the first
storage room 710 and quickly supplies the cool air into the ice
maker 452. A structure of the cooling fan 459 may be applicable in
the same manner to the previously described embodiments.
[0210] A water tank 290 is disposed inside the second storage room
720. A water supply passage 292 is detachably connected to the
water tank 290. Although the water supply passage 292 for supplying
water into the ice maker 452 is directly connected to a water
supply source along a well defining a refrigerator body 10 in the
present embodiment, the present disclosure is not limited thereto.
For example, the same structure as those of the embodiments shown
in FIGS. 13 and 14 may be applicable in the present embodiment.
[0211] In the present embodiment, a portion of the first door 730
covers a portion of an upper side of the second storage room 740.
Thus, a frame 722 for preventing cool air from leaking is disposed
at a front side of the second storage room 720 corresponding to a
region in which a lower end of the first door 730 is in contact
with an upper end of the second door 740. That is, a gasket
disposed on a back surface of the lower end of the first door 730
and a gasket disposed on a back surface of the upper end of the
second door 740 are closely attached to a front surface of the
frame 722 to prevent the cool air from leaking.
[0212] In another embodiment, when the first door 730 has a size in
which only the first storage room 710 is covered, a separate frame
may be not necessary, and the partition 190 may serve as the
frame.
[0213] Also, in the present embodiment, a dispensing structure for
dispensing drinking water may be not provided in the dispenser 736,
and only an ice dispensing structure may be provided in the
dispenser 736. In this case, the water supply tank 290 and the
water supply passage 292 for supplying the drinking water may be
not necessary.
[0214] According to the above-described structure, like the
previously described embodiment, when the first door 730 is
withdrawn, the ice making assembly 450 is maintained in a state in
which the ice making assembly 450 is fixed inside the first storage
room 710. That is, since the ice making assembly 450 need not be
frequently exposed to the outside by a user, the ice making
assembly 450 is not exposed to the outside even if the doors 730
and 740 are withdrawn.
[0215] In the present embodiment, since the ice making assembly 450
is fixed inside the first storage room 710, a separate insulation
wall structure surrounding the entire ice making assembly 450 need
not be provided. That is, it may be enough to provide only the
insulation wall 711. However, a separate insulation wall defining
the ice making compartment may be provided according to a design
condition. The insulation wall 711 may be pivotably provided about
an upper end thereof to allow the ice making assembly 450 to be
separated.
[0216] The two doors for respectively opening and closing the first
storage room 710 and the second storage room 720 may be integrally
formed in one body. That is, the first door 730 and the second door
740 are not divided, i.e., a single door may be provided to
selectively open and close the first storage room 710 and the
second storage room 720. This structure is referred to as a
plurality of storage rooms/single door structure. In this case,
when the second storage room 720 is opened, the first storage room
710 may be opened together. However, the insulation wall 711 may
prevent an external air from being introduced into the first
storage room 710. Also, in case of the single door structure, the
frame 722 need not be provided.
[0217] On the other hand, the first door 730 may be divided into
two doors.
[0218] In detail, the first door 730 may be divided into an upper
door for covering only the ice making compartment 710 and a lower
door including the dispenser. The upper door may open and close the
ice making compartment instead of the insulation wall 711. A
dispenser 736 may be disposed in the lower door, and a receiving
part may be disposed at a rear side of the dispenser 736. Thus, the
second storage room 720 may be opened and closed by the lower door
including the dispenser 736 and the second door 740. This structure
is referred to as a plurality of storage rooms/a plurality of doors
structure. That is, one door may open and close a portion or the
whole of one storage room.
[0219] FIG. 17 is a front perspective view of a refrigerator
according to another embodiment, and FIG. 18 is a partial
cross-sectional view of a refrigerator according to the
embodiment.
[0220] In the present embodiment, an ice making assembly is fixed
inside a storage room, and only a dispenser is disposed on a back
surface of a door for opening and closing the storage room. Thus,
the storage room forms one space.
[0221] Referring to FIGS. 17 and 18, a refrigerator 1 according to
the present embodiment includes a refrigerator compartment 30, a
freezer compartment 20, and a storage room 760 defined at a side of
the refrigerator compartment 30.
[0222] In detail, the storage 760 is provided in one space, and an
ice making compartment 460 is defined above the storage room 760.
As described above, the ice making compartment may be separated
from the storage room 760 by a separate insulation wall structure.
According to the separate insulation wall structure, an internal
temperature of the ice making compartment 460 may be different from
that of the storage room 760. An ice making assembly 450 is
received into the storage room 760. The storage room 760 includes
an ice maker 452, an ice bank 454, an electric motor 456, a crusher
457, and an auger 458, and/or a cooling fan 459. A front surface of
one of insulation walls defining the ice making compartment 460 may
be pivotably disposed about an edge portion of a side thereof to
allow the ice making assembly 450 to be separated. A discharge hole
461 for discharging ice is defined in a bottom surface of one of
the insulation walls defining the ice making compartment 460.
[0223] An opened front surface of the storage room 760 is
selectively covered by a door 750. The door 750 may have a
configuration and size in which the first door and the second door
of the previously described embodiment are integrally formed in one
body. A dispenser 736 is disposed at a side of the door 750. That
is, a recess portion for receiving a container is disposed on a
front surface of the door 750, and an ice suit 748 for guiding a
discharge of ice is disposed in a back surface of the door 750.
When the door 750 is completely closed, an upper end of the ice
suit 748 communicates with the discharge hole 461. Thus, the ice
discharged from the ice bank 456 passes through the discharge hole
461, is guided by the ice suit 748, and is discharged from the
dispenser 736.
[0224] Although not shown, the ice making compartment 460 may be
disposed on the back surface of the door 750 to provide a structure
in which the ice making compartment 460 is withdrawn together with
the door 750. This will be construed as being included in the
present disclosure.
[0225] Also, the door 750 may be partitioned into two doors, and
the storage room 760 may be also partitioned into two storage
rooms. It may be easily modified from FIGS. 17 and 18 by those
skilled in the art. That is to say, the door 750 may be partitioned
into a first door including the dispenser 736 and/or the receiving
part and a second door including only the receiving part. Also, the
storage room 760 corresponding to the door 750 may be partitioned
into a first storage room receiving the ice making assembly 460 and
a rear end portion of the dispenser 736 and a second storage room
receiving the receiving part disposed on the second door. Thus, the
partitioned first storage room may be opened and closed by the
first door, and the partitioned second storage room may be opened
and closed by the second door. Of course, the ice making assembly
460 is fixed inside the partitioned first storage room. This
structure is referred to as a plurality of storage rooms/a
plurality of doors structure. Thus, one door may open and close one
storage room.
[0226] FIG. 19 is a front perspective view of a refrigerator
according to another embodiment, and FIG. 20 is a partial
cross-sectional view of a refrigerator according to the
embodiment.
[0227] In the present embodiment, a storage room separated from a
refrigerator compartment and a freezer compartment and a door for
opening and closing the storage room are provided in one space and
a single door to provide only a dispenser for dispensing drinking
water within the door.
[0228] Referring to FIGS. 19 and 20, a body 10 of a refrigerator 1
according to the present embodiment includes a refrigerator
compartment 30, a freezer compartment 20, and a storage room 760.
The storage room 760 is covered by a drawer-type door 750 that is
slidingly withdrawn.
[0229] In detail, at least one or more receiving parts are disposed
on a back surface of the door 750. A variety of containers is
seated on the receiving parts 754. A dispenser 756 having a
recessed shape and dispensing drinking water is disposed in a front
surface of the door 750. A water supply passage 292 extends up to a
top surface of the dispenser 756.
[0230] In further detail, a water tank 290 is disposed inside the
storage room 760. The water supply passage 292 extends from the
water tank 290 up to the dispenser 256. As shown in FIG. 20, the
separate water tank 290 for supplying the drinking water may be
provided. Alternatively, the water supply passage 292 may be
directly connected to a water supply source.
[0231] The water supply passage 292 has one end detachably
connected to the water tank 290. Thus, when the door 750 is opened,
the water supply passage 292 is separated from the water tank 290,
and when the door 750 is completely closed, the water supply
passage 292 is coupled to the water tank 290.
[0232] Although the dispenser 756 is disposed at an upper portion
of the door 750 in the present embodiment, the present disclosure
is not limited thereto. For example, like a dotted portion shown in
FIG. 19, the dispenser 756 may be disposed at a position near to
the door 750. Therefore, a user having a small height such as a
child may easily dispense ice and water.
[0233] Also, although a dispenser for dispensing ice is not
provided, and only a dispenser for dispensing drinking water is
provided in the present embodiment, as well as, the door 750 for
opening and closing the storage room 737 is provided in only one as
an example, the present disclosure is not limited thereto. For
example, the door 750 for opening and closing the storage room may
be provided in plurality, like the previously described
embodiment.
[0234] For example, doors for opening and closing the storage room
may be disposed at upper and lower sides, respectively, and a
dispenser for dispensing the drinking water may be disposed on any
one door. Also, the storage room 760 may be partitioned into a
plurality, and the partitioned storage rooms may be maintained at
temperatures different from each other.
[0235] FIG. 21 is a vertical cross-sectional view of a refrigerator
according to another embodiment, FIG. 22 is a bottom perspective
view illustrating a first door of a refrigerator according to the
embodiment, and FIG. 23 is a rear perspective view illustrating a
second door of a refrigerator according to the embodiment.
[0236] Referring to FIGS. 21 to 23, in the present embodiment, a
first door 730 covers the whole of a first storage room 710 and a
portion of a second storage room 720. A second door 740 covers a
remaining portion of the second storage room 720. Moreover, an ice
making assembly 450 is disposed on a back surface of the first door
730 corresponding to a region in which the portion of the second
storage room 720 is covered. A dispenser 746 for dispensing ice
and/or water is disposed in a front surface of the second door
740.
[0237] In the present embodiment, a water supply passage 292 for
supplying the water into an ice maker 452 and the dispenser 746 is
directly connected to a water supply source. When the first door
730 and/or the second door 740 are/is withdrawn, the water supply
passage 292 is separated at any position, and the water supply is
stopped by an opening/closing valve V disposed at the separated
position.
[0238] A partition or a frame may be not provided between a lower
end of the first door 730 and an upper end of the second door 740,
and a pillar 50 may be pivotably disposed on a back surface of the
lower end of the first door 730. A structure and operation of the
pillar 50 will be described below in detail with reference to
accompanying drawings.
[0239] A discharge duct 462 for guiding a withdrawal of ice is
disposed at a front side of a bottom surface of the ice making
assembly 450 and extends toward the dispenser 740. In detail, an
ice suit 748 for guiding the withdrawal of the ice is disposed at
an upper side of the dispenser 740. An end portion of the discharge
duct 462 extends near to an inlet port of the ice suit 748.
[0240] The discharge duct 462 does not extend below an upper end of
the second door 740. That is, an end portion of the discharge duct
462 may maximally extend up to a plane L1 horizontally parallel to
the upper end of the second door 740. This is done because it
prevents the discharge duct 462 form interfering with the second
door 740 when the first door 730 is opened in a state where the
second door 740 is closed.
[0241] The inlet port of the ice suit 748 protrudes toward the
discharge duct 462. However, the inlet port does not extend above a
plane L2 horizontally parallel to a lower end of pillar 50. That
is, this is done because it prevents the inlet port of the ice suit
748 from interfering with the pillar 50 when the second door 740 is
opened in a state where the first door 730 is closed.
[0242] Dampers D may be disposed inside the discharge duct 462 and
the ice suit 748, respectively, to prevent the ice from being
dispensed when any one of the first door 730 and the second door
740 is opened.
[0243] As a result, the end portion of the discharge duct 462 is
not closely attached to the inlet port of the ice suit 748. Thus,
the dampers D may be manipulated to prevent cool air supplied into
an ice maker 460 from leaking into the second storage room 720 or
the dispenser 746. For this, a passage formed by the discharge duct
462 and the ice suit 748 is covered by the dampers D, except when
the ice is dispensed.
[0244] The end portion of the discharge duct 462 has an inside
diameter d1 equal to or less than that of the inlet port of the ice
suit 748 to prevent a portion of the ice from being introduced into
the second storage room 720.
[0245] Referring to FIG. 21, a rail member 60 may be disposed on
both lateral surfaces of the receiving part 734. The rail member
may 60 be withdrawn in multi-step. That is, the rail member 60
include fixed rails 61 respectively fixed to the both lateral
surfaces of the receiving part 734 and a movement rail 62 movably
connected to the fixed rails 61. A support structure for slidingly
supporting the rail member 60 may be disposed on an inner sidewall
of the second storage room 720. The rail member 60 has the same
structure as or is similar to a rail member that will be described
in detail in the following embodiment.
[0246] FIG. 24 is a side cross-sectional view of a refrigerator
according to another embodiment.
[0247] Referring to FIG. 24, a refrigerator according to the
present embodiment has the same structure as that shown in FIG. 21,
except that an ice making compartment 460 is fixed inside a storage
room.
[0248] As shown in FIG. 24, the ice making compartment 460 is fixed
to a rear surface of a second storage room 720, and an ice making
assembly 450 is received into the ice making compartment 460. Thus,
a portion of an upper side of the first door 730 covers the whole
of the first storage room 710, and a portion of a lower side of the
first door 730 covers a portion of the second storage room 720. A
dispenser 746 is disposed on a back surface of the second door 740,
and the second door 740 covers the remaining portion of the second
storage room 720.
[0249] A discharge duct 462 extends from a bottom surface of the
ice making compartment 460, and an end portion of the discharge
duct 462 extends toward an ice suit 748 disposed above the
dispenser 746. That is to say, the discharge duct 462 may
inclinedly extend in a front direction up to an inlet port of the
ice suit 748. This is done because the ice making compartment 460
is not moved even if the first door 730 is withdrawn forwardly, and
because it does not matter that the end portion of the discharge
duct 462 extends up to a position lower than that of an upper end
of the second door 740. This is different from the embodiment of
FIG. 21. Thus, since a distance between a lower end of the
discharge duct 462 and an inlet of the ice suit 748 may be
minimized, leakage of cool air may be minimized. Of course, in case
of the present embodiment, dampers D may be disposed inside the
discharge duct 462 and the ice suit 748, respectively.
[0250] FIGS. 25 and 26 are partial perspective views of a power
supply structure connected to a water supply passage and a
dispenser provided in a refrigerator according to an embodiment,
and FIG. 27 is a cross-sectional view taken along line B-B of FIG.
26.
[0251] A water supply passage and a wire shown in FIGS. 25 to 27
may be commonly applicable to all of the previously described
embodiments and the following embodiments. It is to be understood
that the water supply passage is merely illustrative of one of
various embodiments. A structure of a refrigerator, based on the
structure of the refrigerator shown in FIG. 21, will be described
below.
[0252] Referring to FIG. 25, a water supply passage 292 extending
from a water tank or a water supply source extends along a sidewall
of a refrigerator body 10. The water supply passage 292 extends up
to a front surface of the sidewall of the refrigerator body 10, and
an opening/closing valve V is disposed at an end portion of the
water supply passage 292.
[0253] Referring to FIG. 26, a water supply passage 292 for
dispensing drinking water within a second door 740 extends toward a
dispenser. An end portion of the water supply passage 292 protrudes
from an edge portion of a back surface of the second door 740. The
end portion of the water supply passage 292 is selectively coupled
to the opening/closing valve V. That is, when the second door is
completely closed, the water supply passage of the refrigerator
body 10 and the water supply passage of the second door 740 are
connected to each other, and the opening/closing valve V is
opened.
[0254] Although only the water supply passage for dispensing the
drinking water extends along the refrigerator body in the present
embodiment, the present disclosure is not limited thereto. For
example, when an ice making compartment is fixed to the first door
or the second door, a water supply passage for making ice may be
realized also using the same manner.
[0255] As described above, rail members 60 are disposed on both
lateral surfaces of a portion corresponding to a bottom surface of
a receiving part 734. A wire P extends inside one rail member 60
and is connected to a controller (not shown) for operating a
display or dispenser disposed in the second door 740.
[0256] Referring to FIG. 27, the wire P extends inside a fixed rail
61 fixed to a lateral surface of the receiving part 734. The wire P
may be wound in a spiral shape and have a predetermined elasticity.
Thus, the wire P may extend according to forward and backward
movements of the second door 740, and then, returns to prevent the
wire from being damaged.
[0257] FIGS. 28 and 29 are partial perspective views of a power
supply structure connected to a dispenser of a refrigerator
according to another embodiment.
[0258] Referring to FIGS. 28 and 29, a refrigerator according to
the present embodiment has the same structure as that shown in
FIGS. 25 and 26, except for a power supply structure. Thus,
duplicated descriptions of other components except for the power
supply structure will be omitted.
[0259] In detail, in the present embodiment, a wire P extends along
an inner sidewall of a refrigerator body 10. A socket 600 may be
disposed on a front surface of the sidewall of the refrigerator
body 10, i.e., a surface in contact with a back surface of a first
door 730 or a second door 740. The wire P is connected to the
socket 600.
[0260] A plug 601 may protrude from a surface corresponding to the
socket 600 of the back surface of the second door 740 (or the first
door 730). A battery 602 for an electric charging may be laid
inside the second door 740 and be connected to the plug 601. The
battery 602 is electrically connected to a controller for
controlling operations of a display attached to a front surface of
the second door 740 and other electric components. It is obvious
that the plug 601 may be disposed on the refrigerator body 10, and
the socket 600 may be disposed on the second door 740.
[0261] When the second door 740 is completely closed, the plug 601
is inserted into the socket 600. Thus, current flows to charge the
battery 602. When the second door 740 is withdrawn forwardly, the
plug 601 is separated from the socket 600 to stop the charging.
[0262] When the second door 740 is completely closed, a variety of
electric components including the display disposed on the second
door 740 is operated by the current supplied through the wire p. On
the other hand, when the second door 740 is opened, the display and
other electric components are operated by the current supplied from
the battery 602.
[0263] FIGS. 30 and 31 are partial perspective views of a
refrigerator according to another embodiment.
[0264] Referring to FIGS. 30 and 31, in the present embodiment, an
ice making compartment is defined on a back surface of a storage
compartment door, and an ice making assembly and a dispenser are
received into the ice making compartment. A structure in which a
water supply passage for making ice and a water supply passage for
dispensing drinking water extend toward a door will be described in
detail.
[0265] For easy understanding of description, a structure according
to the present embodiment, realized on a back surface of a second
door 740 for opening and closing a second storage room, will be
described below.
[0266] In detail, an ice making compartment 770 is vertically
disposed on a back surface of the second door 740. An ice making
compartment door 771 is pivotably disposed on a side of the ice
making compartment 770.
[0267] An ice maker 452 and an ice bank 454 constituting an ice
making assembly 450 are received into the ice making compartment
770. An auger 458 and a crusher 457 are provided inside the ice
bank 454. An electric motor (not shown) for operating the auger 458
and the crusher 457 may be laid inside the second door 740. In
detail, the ice maker 452 may be disposed on an inner top surface
of the ice making compartment 770, and the ice bank 454 may be
detachably disposed direct below the ice maker 452. A dispenser 746
including an ice suit 748 is disposed at a lower side of the ice
bank 454. That is, the ice bank 454 may be detachably disposed on a
top surface of the dispenser 748. The ice bank 454 may be slidingly
movable laterally from the top surface of the dispenser 748. Thus,
a user may open the ice making compartment door 771 to easily
separate the ice bank 454 from a refrigerator in a state where the
second door 740 is withdrawn.
[0268] Although a transfer unit including the auger 458 and the
crusher 457 extends forwardly and backwardly in the present
embodiment, the present disclosure is not limited thereto. For
example, a vertical auger structure disclosed in U.S. Issued U.S.
Pat. No. 6,082,103 may be applicable to the present embodiment.
Also, an auger structure, in which a rotation axis is inclined,
disclosed in Korean Published Applications No. 2008-0053503 may be
applicable to the present embodiment. Here, the rotation axis may
extend in a direction crossing the second door 740 and may be
inclined in up and down or left and right directions. Or, the
rotation axis may extend in a direction parallel to the second door
740 and may be inclined in a vertical direction.
[0269] A pair of water supply passages 292 within sidewalls of a
second storage room 720 opened and closed by the second door 740
may extend in a front direction, and opening/closing valves V may
be disposed at front ends of the water supply passages 292. End
portions of the water supply passages selectively coupled to the
opening/closing valves V may protrude from an edge portion of a
back surface of the second door 740. Since structures of the water
supply passages ware previously described, duplicated descriptions
thereof will be omitted.
[0270] A receiving part 744 may be disposed at a rear side of the
ice making compartment 770, and rail members may be disposed on
both lateral surfaces of the receiving part 744 to allow the second
door 740 to be withdrawn forwardly.
[0271] FIG. 32 is a perspective view illustrating a structure of an
ice-making assembly of a refrigerator according to an
embodiment.
[0272] Referring to FIG. 32, an overflow prevention unit is
illustrated in the present embodiment. The overflow prevention unit
prevents water supplied into an ice making assembly from
overflowing due to an inertial force generated when a storage room
door is moved forwardly and backwardly.
[0273] In detail, an ice maker 452 is disposed horizontally or
vertically inside an ice making compartment 460. A water supply
passage 292 extends in a direction crossing the ice making
compartment 460 toward the ice maker 452.
[0274] A discharge hole 461 is defined in a bottom surface of the
ice making compartment 460. Also, a guide member is disposed to
transfer ice separated from the ice maker 452 toward the discharge
hole 461. The guide member may include a guide plate 459 extending
from a lateral surface of the ice maker 452. In detail, the guide
plate 459 inclinedly extends downwardly from a lateral end of a top
surface of the ice maker 452 to approach to the discharge hole
461.
[0275] An overflow prevention part 453 may extend from an edge
portion of the top surface of the ice maker 452. In detail, in case
where the ice making compartment 460 is disposed on a storage room
door, water stored in the ice maker 452 may overflow due to inertia
when the storage room door is moved forwardly and backwardly. The
overflow prevention part 453 may be provided to prevent the water
from overflowing. The overflow prevention part 453 may have a
structure in which water overflowing by the inertia returns again
to the ice maker 452. That is, the overflow prevention part 453 may
extend in a direction crossing an inertia direction, and an upper
portion thereof may be rounded. Thus, the water soars upwardly from
the ice maker 452 flows along an inner surface of the overflow
prevention part 453 to return again to the ice maker 452. The
overflow prevention part 453 may have various shapes according to
an internal structure of the ice making compartment 460 and an
installation direction of the ice maker 452. Alternatively, a
residual water tray for receiving the overflowing water may be
disposed on a bottom surface of the ice maker 452.
[0276] In the present disclosure, the ice making assembly may be
defined as an ice making mechanism, as well as, a structure
including the ice making assembly and the ice making compartment
may be inclusively defined also as the ice making mechanism. That
is, a structure including at least ice making assembly may be
defined as the ice making mechanism. It may be widely construed
that the ice making compartment denotes a physical configuration
such as an insulation wall structure surrounding the ice making
assembly as well as an inner space defined by the insulation wall
structure.
[0277] Also, the storage room disclosed in the present disclosure,
i.e., the first storage room and the second storage room may be
used as one of the refrigerator compartment and the freezer
compartment. In addition, the storage room may be used as the
switching room in which the refrigerator compartment and the
freezer compartment may be mutually converted according to a user s
selection or a driving condition.
[0278] In a structure of the refrigerator according to the
previously described embodiments, the slidable door that is movable
in forward and backward directions, but the pivotable door, is
provided at a side of the refrigerator door. Thus, when the
refrigerator is installed at an edge portion of an indoor space, a
door closely attached to a wall is not rotated at an angle greater
than about 90 degrees. However, the prevent disclosure may overcome
such a limitation.
[0279] Also, the storage room disclosed in the present disclosure
has a width relatively narrower than the refrigerator compartment.
However, since long containers such as a bottle may be easily
received into the storage room, space utilization of the inside of
the refrigerator may be improved.
[0280] FIG. 33 is a perspective view illustrating an outer
appearance of a refrigerator according to an embodiment, and FIG.
34 is a perspective view of a refrigerator when a refrigerator door
is opened, according to an embodiment.
[0281] Referring to FIGS. 33 and 34, a refrigerator of the present
embodiment is almost similar to those of FIGS. 1 and 2. However, a
separate barrier for partitioning the inside of the refrigerator is
not provided, and a refrigerator door for opening and closing a
refrigerator compartment defined in one space includes a pivotable
door and a plurality of slidable doors.
[0282] In detail, a refrigerator according to the present
embodiment includes a body 10 in which a refrigerator compartment
30 and a freezer compartment are defined, a refrigerator
compartment door 32, a freezer compartment door 22, a first door
130, and a second door 140. The refrigerator compartment 30 and the
freezer compartment are selectively covered by the refrigerator
compartment door 32, the freezer compartment door 22, the first
door 130, and the second door 140, respectively. Also, an outer
appearance of the refrigerator is defined by the doors.
[0283] The refrigerator compartment 30 and the freezer compartment
20 are defined at upper and lower portions of the body 10,
respectively. The refrigerator compartment 30 is covered by the
refrigerator compartment door 32, the first door 130, and the
second door 140. The freezer compartment 20 is covered by the
freezer compartment door 22.
[0284] In detail, the refrigerator compartment door 32 covers a
portion of an opened front surface of the refrigerator compartment
30 and is pivotably disposed on a body 10. For this, the
refrigerator compartment door 32 is coupled to the body 10 by a
hinge 34.
[0285] A vertical length of the refrigerator compartment door 32
corresponds to a vertical length of the refrigerator compartment
30. Also, the refrigerator compartment door 32 has a width less
than that of the refrigerator compartment 30. Thus, the
refrigerator door 32 may covers a remaining portion, exclusive of a
predetermined horizontal width of the refrigerator compartment 30,
by a rotation thereof.
[0286] Al least portion of the refrigerator compartment door 32 may
be formed of a transparent or translucent glass material to enable
the refrigerator compartment 30 to be viewed through the
refrigerator compartment door 32. Specifically, even foods received
in a first door 130 and a second door 140 that will be described
below may be viewed through the refrigerator compartment door 32
from the outside.
[0287] A front surface of the refrigerator door 32 may be formed of
a glass material, and a circumference thereof may be formed of a
plastic or metallic material. Data inputted form the outside may be
displayed through the glass of the refrigerator compartment door
32, and operation information of the refrigerator 1 may be also
displayed.
[0288] A front surface of the refrigerator compartment 30, which is
not covered by the refrigerator compartment door 32, may be covered
by the first door 130 and the second door 140, respectively. An
opened front surface of the refrigerator compartment 30 may be
covered by the refrigerator compartment door 32 and another door,
or may be covered by two or more doors.
[0289] A plurality of shelves 12 and drawers 14 is provided inside
the refrigerator compartment 30 to store foods. The shelves 12 and
drawers 14 are disposed at a rear side of the refrigerator door 32
and have horizontal widths less than that of the refrigerator
compartment door 32. Thus, when only the refrigerator compartment
door 32 is opened, each of the drawers 14 and shelves 12 may be
withdrawable without interfering.
[0290] The shelf 12 is detachably disposed in a cantilever manner
on an inner rear surface of the refrigerator compartment 30. Also,
the shelf 12 may be detached at an inner space of the refrigerator
compartment 30 to adjust a height thereof.
[0291] The first door 130 and the second door 140 are disposed at a
left side of the refrigerator compartment door 32 to cover a left
space of the refrigerator compartment 30. The first door 130 may be
disposed above the second door 140.
[0292] The first door 130 and the second door 140 may be
withdrawable in a drawer-type. Door handles 132 and 144 may be
disposed on front surfaces of the first door 130 and the second
door 140. Receiving parts (reference numerals 134 and 146 of FIG.
3) for receiving foods may be disposed at a rear side of the first
door 130 and the second door 140. An ice making compartment
(reference numeral 160 of FIG. 3) for making and storing ice is
disposed at the rear side of the second door 140.
[0293] A dispenser 142 for dispensing drinking water and the ice at
the outside is disposed in a front surface of the second door 140.
The dispenser 142 communicates with the ice making compartment 160
to dispense the ice stored in the ice making compartment 160 at the
outside and is connected to an external water supply source by a
water supply passage to dispense the drinking water.
[0294] Dispensing holes for respectively dispensing the made ice
and the drinking water and a manipulation unit may be disposed in
the dispenser 142. A residual water tray for receiving residual
water generated when the ice or the drinking water is dispensed may
be disposed below the dispenser 142. A display for illustrating an
operation state of the refrigerator may be disposed above the
dispenser 142.
[0295] FIG. 35 is an exploded perspective view of a refrigerator
when a first door and a second door are withdrawn, according to an
embodiment, and FIG. 36 is a cross-sectional view taken along line
C-C of FIG. 35 when the first door is closed.
[0296] Referring to FIGS. 35 and 36, a first door 130 and a second
door 140 may be withdrawn forwardly and backwardly by a rail member
60 inside a body 10.
[0297] The rail member 60 includes a mounting rail 63 mounted on a
rail mounting member 70 disposed on the body 10, a movement rail 62
slidingly moved inside the mounting rail 63, and a fixed rail 61
disposed on the first door 130 or the second door 140, slidingly
moved along the movement rail 62, and connected to a slidable
door.
[0298] The rail member 60 may extend in multi-step so that the rail
member 60 has sufficient length to completely withdraw receiving
parts 134 and 146 disposed on the first door 130 and the second
door 140 to the outside when the first door 130 and the second door
140 are withdrawn.
[0299] Thus, the first door 130 and the second door 140 may be
slidingly withdrawn forward and backward by the rail member 60, and
thus, it is possible that a portion of the refrigerator compartment
30 is opened to expose the receiving parts 134 and 146 to the
outside.
[0300] The rail member 60 may be disposed on another side of an
upper side and/or a lower side and left and right sides of the
first door 130 and the second door 140, except for a side of left
and right sides of the first door 130 and the second door 140.
[0301] In detail, the rail mounting member 70 may be disposed on an
inner sidewall of the refrigerator compartment 30 adjacent to the
first door 130. The rail mounting member 70 is disposed to support
and mount the rail member 60. The rail mounting members 70 may be
disposed in front and rear directions and at positions
corresponding to a top surface and left side surface of the first
door 130, respectively.
[0302] One or more rail mounting members 70 disposed on an inner
sidewall of the refrigerator compartment 30 corresponding to the
left side surface of the first door 130 may be provided according
to a vertical length of the first door 130.
[0303] The movement rail 62 is fixed to the mounting rail 63
mounted on the rail mounting member 70. The fixed rail 61 is fixed
to a top surface and left and right surfaces of the first door 130.
The mounting rail 63, the movement rail 62, and the fixed rail 61
may be slidingly movable in a length direction. Thus, the first
door 130 may be withdrawn in a state where the first door 130 is
hanged on inner upper and left sides of the refrigerator
compartment 30.
[0304] The rail mounting member 70 may be disposed also inside the
refrigerator compartment 30 adjacent to the second door 140. The
rail member 60 and the rail mounting member 70 have the same
structure as those of the first door 130, except for installation
positions thereof, and thus, will be given by the same reference
numerals.
[0305] In detail, the rail mounting member 70 is disposed on an
inner bottom surface of the refrigerator compartment 30
corresponding to a bottom surface of the second door 140 and inner
left and right side surfaces of the refrigerator compartment 30
corresponding to the left and right side surfaces of the second
door 140.
[0306] The mounting rail 63 of the rail member 60 is mounted on the
rail mounting member 70. The movement rail 62 is mounted on the
mounting rail 63. The fixed rail 61 is mounted on a left side
surface and a bottom surface of the second door 140. Thus, the
second door 140 may be withdrawn in a state where the second door
140 is supported by the bottom surface and the left side surface of
the refrigerator compartment 30.
[0307] The rail mounting member 70 and the rail member 60 are
disposed on the inner sidewall of the refrigerator compartment 30.
However, when a separate storage space, such as the drawer 14 or
the storage room (reference numeral 102 of FIG. 41), adjacent to
the slidable door is provided, the rail mounting member 70 and the
rail member 60 may be disposed at corresponding positions to assist
the withdrawal of the slidable door.
[0308] A withdrawal guide 42 vertically protruding from an inner
top surface and/or an inner bottom surface of the refrigerator
compartment 30 may be disposed to prevent the door from being
shaken during the withdrawal of the door. The withdrawal guide 42
protrudes to contact with a lateral surface of the slidable door.
That is, the withdrawal guide 42 is in contact with a lateral upper
end or lower end of the slidable door. In addition, the withdrawal
guide 42 may be disposed in front and rear directions to stably
guide the slidable door during the withdrawal of the slidable
door.
[0309] If necessary, the rail mounting member 70 and the rail
member 60 may be disposed on the withdrawal guide 42. The
withdrawal guide 42 may be disposed without covering foods received
in the slidable door.
[0310] An ice making compartment 160 for making and storing ice is
disposed at a lower side of a back surface of the second door 140.
The ice making compartment 160 communicates with the dispenser 142.
If necessary, an additional rail member 60 for guiding the
withdrawal of the second door 140 may be further provided between a
left side surface of the ice making compartment 160 and a right
side surface of the drawer 14, which are adjacent to each
other.
[0311] The ice making compartment 160 may be disposed at an upper
or lower portion of the second door 140. Thus, the receiving part
146 may be disposed also at the upper or lower portion of the
second door 140.
[0312] FIG. 37 is a perspective view of a refrigerator when a first
door is opened, according to another embodiment, FIG. 38 is a
cross-sectional view taken along line C-C of FIG. 37 when the first
door is closed, and FIG. 39 is a bottom perspective view of a first
door according to another embodiment.
[0313] Referring to FIGS. 36 to 39, a refrigerator of the present
embodiment has the same structure as that of FIG. 8, except that a
separate barrier for partitioning the inside of the refrigerator is
not provided, the refrigerator defined as one space is covered by a
refrigerator compartment door, a first door, and a second door, and
a pillar is disposed between the first door and the second
door.
[0314] In detail, a body 10 is vertically partitioned into a
refrigerator compartment 30 and a freezer compartment 20. A portion
of the refrigerator compartment 30 is covered by a refrigerator
door 32, and another portion of the refrigerator compartment 30 is
covered by a first door 430 and a second door 440.
[0315] The refrigerator compartment door 32 is coupled to the body
10 using a hinge 34, and thus is pivotally opened and closed. A
portion of a front surface of the refrigerator compartment door 32
may be transparent to enable the refrigerator compartment 30 to be
viewed through the refrigerator compartment door 32. The first door
430 and the second door 440 may be vertically disposed at a side of
the refrigerator compartment door 32. The first door 430 and the
second door 440 may be disposed inside the refrigerator compartment
30 and slidingly withdrawn by a rail member 60.
[0316] The rail member 60 for withdrawing the first door 430 is
disposed on inner upper and left side surfaces of the refrigerator
compartment 30 to support and slidingly move the first door 430.
The rail member 60 for withdrawing the second door 440 is disposed
on inner lower and left side surfaces of the refrigerator
compartment 30 to support and slidingly move the first door
430.
[0317] Receiving parts 434 and 442 for receiving foods are disposed
on the first door 430 and the second door 440. A dispenser 436 for
dispensing water and ice is disposed in a front surface of the
first door 430. Considering a height of a user, the dispenser 436
may be disposed at a lower side of the first door 430.
[0318] An ice making compartment 460 is disposed at an upper side
of the first door 430. An ice maker 452 and an ice bank 454 are
received into the ice making compartment 460. The ice making
compartment 460 may be formed with an independent insulation space
within the refrigerator compartment 30.
[0319] The ice making compartment 460 may be detachably coupled to
a back surface of the first door 430 and may be integrally formed
by a door liner defining the back surface of the first door
430.
[0320] The ice making compartment 460 may extend from the back
surface of the first door 430 toward a rear direction, and thus may
be adjacent to a rear surface of the refrigerator compartment 30.
Also, when the first door 430 is completely inserted, a cool air
duct 480 disposed inside the body 10 communicates with the inside
of the ice making compartment 460.
[0321] In detail, the cool air duct 480 includes a supply duct for
guiding cool air into the ice making compartment 460 and a return
duct for guiding the cool air toward an evaporator. A cool air
inlet 462 and a cool air outlet 464 are defined in a rear wall of
the ice making compartment corresponding to the supply duct 482 and
the return duct 484, respectively.
[0322] Thus, when the first door 430 is completely inserted, the
supply duct 484 may communicate with the cool air inlet 462, and
the return duct 484 may communicate with the cool air outlet 464 to
continuously circulate the cool air between the ice making
compartment 460 and the evaporator.
[0323] An auger 458 operated by an electric motor 456 and a crusher
457 disposed on the same rotation axis to crush the ice are
disposed in the ice bank 454 within the ice making compartment 460.
A power source for operating the electric motor 456 of the ice bank
454 and the ice maker 452 may be inputted by a power connector
connected to the electric motor 456 and the ice maker 452 when the
first door 430 is completely inserted.
[0324] A water tank 490 for supplying the water into the ice maker
452 and the dispenser 436 is disposed at a side of the ice making
compartment 460. The water tank 490 may be detachably disposed, and
thus filled with a desired amount of the water by a user. Thus,
when the first door 430 is withdrawn, the ice making compartment
460 and the water tank 490 may be withdrawn together with the first
door 430 in front and rear directions.
[0325] The water stored in the water tank 490 may be supplied into
the dispenser 436 and the ice maker 452 through a water supply
passage 492. The water supply passage 492 connects the water tank
490 to the dispenser 436 and the ice maker 452. At least portion of
the water supply passage 492 may be buried inside insulation foam
filled inside the first door 430.
[0326] The water tank 490 may be disposed in the body 10 spaced
from the ice making compartment 460. The water tank 490 may be
connected to a water supply passage directly connected to the ice
maker 452 and the dispenser 436. At this time, the water supply
passage may be selectively connected to a connection part 468
disposed at a side of the ice making compartment 460. A valve may
be disposed in the water supply passage.
[0327] Gaskets 438 for preventing the cool within the refrigerator
compartment 30 air from leaking are disposed on back surfaces of
the first door 430 and the second door 440. A pillar 50 is disposed
at a position adjacent between the first door 430 and the second
door 440.
[0328] The pillar 50 covers a space between the first door 430 and
the second door 440. The pillar 50 is disposed at a lower end of
the back surface of the first door 430. The pillar 50 is
selectively pivoted according to the withdrawal of the first door
430 to selectively cover the space between the first door 430 and
the second door 440.
[0329] In detail, the pillar 50 has a length corresponding to a
horizontal width of the first door 430. When the first door 430 is
inserted, the pillar is pivoted. As a result, a lower end of the
first door 430 and an upper end of the second door 440 are in
contact with a front surface of the pillar 50 to prevent the cool
air within the refrigerator compartment 30 from leaking between the
first door 430 and the second door 440.
[0330] The pillar 50 is hinge-coupled to the lower end of the first
door 430. The pillar 50 is closely attached to the first door 430
by an elastic member 52 in a state where the front surface of the
pillar 50 is inclined downwardly when an external force is not
applied to the elastic member 52. The pillar 50 may be covered by a
front surface of the first door 430. Thus, the pillar 50 may be not
exposed to the outside when viewed from a front direction of the
first door 430.
[0331] The elastic member 52 disposed in the pillar 50 may have a
coil spring shape. The elastic member 52 may connect the pillar 50
to a side of the first door 430. The pillar 50 may be closely
attached the lower end of the first door 430 due to elasticity of
the elastic member 52 if the external force is not applied to the
pillar 50.
[0332] The elastic member 52 may have various shapes except for the
coil spring shape. Also, the elastic member 52 may be disposed at
various positions to provide an elastic force to the pillar 50.
[0333] A guide protrusion 54 protruding outwardly is disposed at
one end of the pillar 50. The guide protrusion 54 may moved along a
guide groove 70 defined in a lateral surface corresponding to the
inside of the refrigerator compartment 30. Surfaces of the guide
groove 70 and the guide protrusion 54, which correspond to each
other, may be rounded with a predetermined curvature to smoothly
rotate the pillar 50.
[0334] In detail, the guide groove 70 is opened in a front
direction and is depressed inwardly. The guide groove 70 is curved
inwardly with a predetermined curvature. A curved part 56
corresponding to the curvature of the guide groove 70 is disposed
on the guide protrusion 54 contacting with the guide groove 70.
Thus, when the guide protrusion 54 of the axially coupled pillar 50
is moved along the guide groove 70 fixed to an inner wall of the
refrigerator compartment 30, the pillar may be rotatable.
[0335] FIG. 40 is a view illustrating successive operations of a
pillar according to another embodiment.
[0336] Referring to FIGS. 37 and 40, when the first door 430 is
opened, the front surface of the pillar 50 is inclined downwardly
due to an elastic restitution force applied by the elastic member
52.
[0337] When the first door 430 is inserted in a rear direction, the
curved part 56 of the guide protrusion 54 contacts with the guide
groove 70. When the first door 430 is further inserted, the pillar
50 is moved backwardly along the first door 430 to rotate about a
rotation axis in a count-clockwise direction. At this time, the
curved part 56 disposed on the guide protrusion 54 is slidingly
moved along an inner surface of the guide groove 70.
[0338] When the first door 430 is completely inserted, the curved
part 56 of the guide protrusion 54 is completely rotated along the
guide groove 70. At this time, the front surface of the pillar 50
is faced in a front direction and is in contact with the lower end
of the first door 430 and the upper end of the second door 440.
[0339] The curved part 56 of the pillar 50 is coupled to the inside
to the guide groove 70. The front surface of the pillar 50 is
rotated by 90 degrees in a count-clockwise direction when compared
to a state in which the first door 430 is opened and is faced in a
front direction of the refrigerator 1.
[0340] In this state, the elastic member 52 completely extends.
When the first door 430 is withdrawn again, the pillar 50 is
rotated in a clockwise direction due to the elastic restitution
force of the elastic member 52. At this time, the curved part 56 of
the pillar 50 is slidingly moved along the guide groove 70.
[0341] FIG. 41 is a perspective view of a refrigerator when a door
is opened, according to another embodiment.
[0342] Referring to FIG. 41, a refrigerator of the present
embodiment has the same structure as that of FIG. 37, except that a

[0351] The first door 430 is disposed inside the body 10, and thus,
is slidingly withdrawn by a rail member 60. At this time, since the
first door 430 is adjacent to an inner upper surface and a left
sidewall of the refrigerator compartment 30, the rail member 60 and
a rail mounting member 70 on which the rail member 60 is mounted
are disposed on the inner top surface and the left sidewall of the
refrigerator compartment 30. Thus, the first door 430 may be
slidingly withdrawn in a state where the first door 430 is
supported by the inner top surface and the left sidewall of the
refrigerator compartment 30.
[0352] The rail member 60 is disposed also on the second door 440
to slidingly withdraw the second door 440. At this time, the rail

[0353] When the first door 430 and the second door 440 are
inserted, a lower end of the first door 430 and an upper end of the
second door 440 are in contact with an upper end of the storage
room 102. Thus, when the first door 430 and the second door 440 are
closed, it may prevent the cool air from leaking between the first
door 430 and the second door 440.
[0354] FIG. 42 is a perspective view of a refrigerator when a door
is opened, according to further another embodiment.
[0355] Referring to FIG. 42, a refrigerator of the present
embodiment has the same structure as that of FIG. 41, except that a
separate storage room is defined at a side of the refrigerator
compartment. Thus, duplicated descriptions with respect to other
configurations except for a configuration of an inner space of the
refrigerator compartment will be omitted.
[0356] In detail, a body 10 of the present embodiment is vertically
partitioned into a refrigerator compartment 30 and a freezer
compartment 20. The refrigerator compartment 30 is selectively
covered by a refrigerator compartment door 32 and a second door
440. The freezer compartment 20 is selectively covered by a freezer
compartment door 22. At this time, an opened front surface of the

maintained at a temperature equal to that of the refrigerator
compartment 20.
[0359] The storage room 104 may be covered by the first door 430,
and the first door 430 may be slidingly withdrawable. A dispenser
436 for dispensing water and ice is disposed in a front surface of
the first door 430. An ice making compartment 460 for making and
storing the ice is disposed on a back surface of the first door 430
to communicate with the dispenser 436.
[0360] Dispensing holes for dispensing drinking water and ice,
manipulation units of manipulating the dispensing holes, and a
residual water tray are further disposed in the dispenser 436, and
a display is disposed above the dispenser 436.
[0361] The ice making compartment 460 is disposed in an upper
portion of the first door 430, and the receiving part 434 is
disposed below the ice making compartment 460. The ice making
compartment 460 and the receiving part 434 are disposed inside the
storage room 104 when the first door 430 is inserted. Also, the ice
making compartment 460 and the receiving part 434 may be
selectively withdrawn from the storage room 104 according to an
opening/closing operation of the first door 430.
[0362] For this, a rail mounting member 70 is disposed on a top
surface and left and right side surfaces of the refrigerator
compartment adjacent to the first door 430. A rail member 60 for
supporting left and right side surfaces and a top surface of the
first door 430 is mounted on the rail mounting member 70. The rail
mounting member 70 and the rail member 60 may be disposed on both
sidewalls of the inside of the storage room 104.
[0363] When the storage room 104 is maintained at a temperature
below zero corresponding to that of the freezer compartment 20, a
separate insulation space may be not defined in the ice making
compartment 460. In detail, the ice making compartment 460 may
provide only a space in which the ice maker 452 and the ice bank
454 are disposed and may be exposed to cool air within the storage
room 104 to make ice. The receiving part 434 disposed on the back

door 32 and the second door 440.
[0368] When the first door 430 and the second door 440 are
inserted, a lower end of the first door 430 and an upper end of the
second door 440 are in contact with an upper end of a front surface
of the storage room 102. Thus, when the first door 430 and the
second door 440 are completely inserted, it may prevent the cool
air from leaking between the first door 430 and the second door
440.
[0369] FIG. 43 is a perspective view of a refrigerator when a door
is opened, according to further another embodiment.
[0370] Referring to FIG. 43, a refrigerator of the present
embodiment has the same structure as that of FIG. 40, except that a

[0377] A dispenser 436 for dispensing water and ice is disposed in
a front surface of the first door 430. An ice making compartment
460 for making and storing the ice is disposed on a back surface of
the first door 430 to communicate with the dispenser 436.
[0378] Dispensing holes for dispensing drinking water and ice,
manipulation units of manipulating the dispensing holes, and a
residual water tray are further disposed in the dispenser 436, and
a display is disposed above the dispenser 436.
[0379] When the storage room 106 is maintained at a temperature
below zero corresponding to that of the freezer compartment 20, a
separate insulation space may be not defined in the ice making
compartment 460. In detail, the ice making compartment 460 may
provide only a space in which the ice maker 452 and the ice bank
454 are disposed and may be exposed to cool air within the storage
room 104 to make ice.
[0380] The ice making compartment 460 is disposed in an upper
portion of the first door 430, and the receiving part 434 is
disposed below the ice making compartment 460. When the first door
430 is closed, the ice making compartment 460 is disposed inside
the storage room 106, and the receiving part 434 is disposed inside
the refrigerator compartment 30 below the storage room 106.
[0381] A rail member 60 is disposed on top and left side surfaces
of the storage room 106 corresponding to top and left side surfaces

434 may be exposed to the outside. When the first door 430 is
inserted, the receiving part 434 of the first door 430 is disposed
inside the refrigerator compartment 30 and may be viewed through
the refrigerator compartment door 32 from the outside.
[0383] The second door 440 is disposed below the first door 430.
The second door 440 may be slidingly withdrawable into the
refrigerator compartment 30 by a rail member 60.
[0384] In detail, since the second door 440 is adjacent to an inner
bottom surface and a left sidewall of the refrigerator compartment
30, the rail member 60 and a rail mounting member 70 on which the
rail member 60 is mounted are disposed on the inner bottom surface
and the left sidewall of the refrigerator compartment 30. Thus, the
second door 440 may be slidingly withdrawn in a state where the
second door 440 is supported by the inner bottom surface and the
left sidewall of the refrigerator compartment 30.
[0385] When the second door 440 is closed, the receiving part 442
of the second door 440 is disposed inside the refrigerator
compartment 30. Thus, foods stored in the receiving part 442 of the
second door 440 may be viewed through the transparent refrigerator
compartment door 32 without opening the refrigerator compartment
door 32 and the second door 440.
[0386] A pillar 50 is disposed at a lower end of the first door 430

a front surface of the first door 430. An ice making compartment
460 for making and storing the ice is disposed on a back surface of
the first door 430 to communicate with the dispenser 436.
[0394] A drinking water dispensing hole, an ice dispensing hole,
manipulation units of manipulating the dispensing holes, and a
residual water tray are further disposed in the dispenser 436, and
a display is disposed above the dispenser 436.
[0395] A rail member 60 is disposed on top and left side surfaces
of the storage room 108 corresponding to top and left side surfaces
of the first door 430. The first door 430 may be withdrawable
forwardly and backwardly by the rail member 60. The rail member 60
disposed on the left side surface of the first door 430 may be
provided in plurality. In this case, the rail members 60 may be
disposed on left side surfaces of the ice making compartment 460
and the receiving part 434, respectively.
[0396] A front surface of the storage room 108 and a portion of the
refrigerator compartment 30 may be selectively covered according to
the withdrawal of the first door 430. When the first door 430 is
withdrawn, the ice making compartment 460 and the receiving part
434 may be exposed to the outside.
[0397] When the first door 430 is inserted, the receiving part 434
of the first door 430 is disposed inside the refrigerator
compartment 30 and may be viewed through the refrigerator
compartment door 32 from the outside.
[0398] The second door 440 is disposed below the first door 430.
The second door 440 may be slidingly withdrawable into the
refrigerator compartment 30 by a rail member 60.
[0399] In detail, since the second door 440 is adjacent to an inner
bottom surface and a left sidewall of the refrigerator compartment
30, the rail member 60 and a rail mounting member 70 on which the
rail member 60 is mounted are disposed on the inner bottom surface
and the left sidewall of the refrigerator compartment 30. Thus, the
second door 440 may be slidingly withdrawn in a state where the
second door 440 is supported by the inner bottom surface and the
left sidewall of the refrigerator compartment 30.
[0400] When the second door 440 is closed, the receiving part 442
of the second door 440 is disposed inside the refrigerator
compartment 30. Thus, foods stored in the receiving part 442 of the
second door 440 may be viewed through the transparent refrigerator
compartment door 32 without opening the refrigerator compartment
door 32 and the second door 440.
[0401] A pillar 50 is disposed at a lower end of the first door 430
to prevent cool air from leaking between the first door 430 and the
second door 440 when the first door 430 and the second door 440 are
closed.
[0402] FIG. 45 is a perspective view of a refrigerator when a door
is opened, according to further another embodiment.
[0403] Referring to FIG. 45, a refrigerator of the present
embodiment has the same structure as that of FIG. 37, except for
configurations of a first door and a second door and a position of
a dispenser. Thus, duplicated descriptions with respect to the
configurations of the first and second doors and the position of
the dispenser will be omitted.
[0404] In detail, a body 10 of the present embodiment is vertically
partitioned into a refrigerator compartment 30 and a freezer
compartment 20. The refrigerator compartment 30 is selectively
covered by a refrigerator compartment door 32, a first door 830,
and a second door 840. The freezer compartment 20 is selectively
covered by a freezer compartment door 22.
[0405] The refrigerator door 32 is coupled to the body 10 using a
hinge 34 to cover a portion of an opened front surface of the
refrigerator compartment 30 by a rotation thereof. Also, the first
door 830 and the second door 840 including receiving parts 834 and
842 may be withdrawn forwardly and backwardly in a drawer-type to
cover the remaining portion of the refrigerator compartment 30.
[0406] The first door 830 and the second door 840 are disposed at a
left side of the refrigerator compartment door 32, and the first
door 830 may be disposed above the second door 840. A rail member
60 for slidingly guiding the withdrawal of the first door 830 is
disposed on top and left side surfaces of the refrigerator
compartment 30 corresponding to the first door 830. The rail member
60 is fixed inside the refrigerator compartment 30 by a rail
mounting member 70.
[0407] The first door 830 may have a vertical length somewhat loner
than that of the second door 840. An ice making compartment 860 is
disposed on an upper portion of a back surface of the first door
830. The ice making compartment 860 provides a space for making and
storing ice. The ice making compartment 860 receives an ice maker
452 and an ice bank 454.
[0408] Since the ice making compartment 860 should be maintained at
a temperature below zero to make the ice, the ice making
compartment 860 may be insulated from the refrigerator compartment
30. A dispenser 836 for dispensing water or ice is disposed at a
rear side of the first door 830.
[0409] In detail, the dispenser 836 is disposed at a lower portion
of the ice making compartment 860. For use s convenience, the
dispenser 836 may be disposed at a middle portion or a lower
portion of the first door 830 to allow a user to access the
dispenser 836. The dispenser 836 communicates with the ice making
compartment 860, and thus, may receive the made ice from the ice
making compartment 860.
[0410] The dispenser 836 is disposed facing the refrigerator
compartment 30 to enable the dispenser 836 and the receiving part
834 to be viewed through the refrigerator compartment door 32 even
through the first door 830 is closed. Also, the dispenser 836 may
be exposed laterally outside the refrigerator compartment 30 when
the first door 830 is slidingly withdrawn.
[0411] A drinking water dispensing hole, an ice dispensing hole,
manipulation units of manipulating the dispensing holes, and a
residual water tray are further disposed in the dispenser 836, and
a display is disposed above the dispenser 836.
[0412] A receiving part 834 having multi-stages is disposed at rear
and lower sides of the dispenser 836 to receive foods.
[0413] The second door 840 is disposed below the first door 830.
The second door 840 may be slidingly withdrawable into the
refrigerator compartment 30 by a rail member 60.
[0414] In detail, since the second door 840 is adjacent to an inner
bottom surface and a left sidewall of the refrigerator compartment
30, the rail member 60 and a rail mounting member 70 on which the
rail member 60 is mounted are disposed on the inner bottom surface
and the left sidewall of the refrigerator compartment 30. Thus, the
second door 840 may be slidingly withdrawn in a state where the
second door 440 is supported by the inner bottom surface and the
left sidewall of the refrigerator compartment 30.
[0415] When the first door 830 and the second door 840 are closed,
the receiving part 834 having the multi-states and the receiving
part 842 disposed on the second door 840 are disposed on the first
door 830. Thus, foods stored in the receiving part 834 and 842 of
the first door 830 and the second door 840 may be viewed through
the transparent refrigerator compartment door 32 even through the
refrigerator compartment door 32 is closed.
[0416] When the refrigerator compartment door 32 is rotated to open
the refrigerator compartment 30, the dispenser 836 is exposed to
the inside of the refrigerator compartment 30. Thus, the user may
use the dispenser 836 without opening the first door 830.
[0417] Vertical lengths of the first door 830 and the second door
840 may be varied as necessary. Thus, the receiving parts 834 and
842 disposed on the first door 830 and the second door 840 may be
variously arranged according to the vertical lengths of the first
door 830 and the second door 840.
[0418] A pillar 50 is disposed at a lower end of the first door 830
to prevent cool air from leaking between the first door 830 and the
second door 840 when the first door 830 and the second door 840 are
closed.
[0419] FIG. 46 is a perspective view of a refrigerator when a door
is opened, according to further another embodiment.
[0420] Referring to FIG. 46, a refrigerator of the present
embodiment has the same structure as that of FIG. 37, except for
configurations of a first door and a second door and a position of
a dispenser. Thus, duplicated descriptions with respect to the
configurations of the first and second doors and the position of
the dispenser will be omitted.
[0421] In detail, a body 10 of the present embodiment is vertically
partitioned into a refrigerator compartment 30 and a freezer
compartment 20. The refrigerator compartment 30 is selectively
covered by a refrigerator compartment door 32, a first door 930,
and a second door 940. The freezer compartment 20 is selectively
covered by a freezer compartment door 22.
[0422] The refrigerator door 32 covers a portion of an opened front
surface of the refrigerator compartment 30 by a rotation thereof.
Also, the first door 930 and the second door 940 including
receiving parts 934 and 942 may be withdrawn forwardly and
backwardly in a drawer-type to cover the remaining portion of the
refrigerator compartment 30.
[0423] The first door 930 and the second door 940 are disposed at a
left side of the refrigerator compartment door 32, and the first
door 930 may be disposed above the second door 940. A rail member
60 for slidingly guiding the withdrawal of the first door 930 is
disposed on top and left side surfaces of the refrigerator
compartment 30 corresponding to the first door 930. The rail member
60 is fixed inside the refrigerator compartment 30 by a rail
mounting member 70.
[0424] A receiving part 934 for receiving foods is disposed at a
rear side of the first door 930. The receiving part 934 may have
one stage or two stages and may have various structures to receive
a variety of foods.
[0425] The second door 940 is disposed below the first door 930.
The second door 940 may be slidingly withdrawable into the
refrigerator compartment 30 by a rail member 60.
[0426] In detail, since the second door 940 is adjacent to an inner
bottom surface and a left sidewall of the refrigerator compartment
30, the rail member 60 and a rail mounting member 70 on which the
rail member 60 is mounted are disposed on the inner bottom surface
and the left sidewall of the refrigerator compartment 30. Thus, the
second door 940 may be slidingly withdrawn in a state where the
second door 940 is supported by the inner bottom surface and the
left sidewall of the refrigerator compartment 30.
[0427] An ice making compartment 960 is disposed on an upper
portion of a back surface of the first door 930. The ice making
compartment 960 provides a space for making and storing ice. The
ice making compartment 960 receives an ice maker 452 and an ice
bank 454.
[0428] Since the ice making compartment 960 should be maintained at
a temperature below zero to make the ice, the ice making
compartment 960 may be insulated from the refrigerator compartment
30. A dispenser 936 for dispensing water or ice is disposed on the
back surface of the second door 940 communicating with the ice
making compartment 960.
[0429] The dispenser 936 is disposed at a lower portion of the ice
making compartment 960. The ice within the ice making compartment
960 may be moved toward the dispenser 936 by a transfer device.
[0430] A drinking water dispensing hole, an ice dispensing hole,
manipulation units of manipulating the dispensing holes, and a
residual water tray are further disposed in the dispenser 936, and
a display is disposed above the dispenser 936.
[0431] The receiving parts 934 and 942 disposed on the first door
930 and the second door 940 are disposed inside the refrigerator
compartment 30 when the first door 930 and the second door 940 are
closed. Thus, foods stored in the receiving part 934 and 942 of the
first door 930 and the second door 940 may be viewed through the
transparent refrigerator compartment door 32 even through the
refrigerator compartment door 32 is closed.
[0432] When the refrigerator compartment door 32 is opened, the
dispenser 936 is exposed to the inside of the refrigerator
compartment 30. Thus, the user may use the dispenser 936 without
opening the second door 940.
[0433] A pillar 50 is disposed at a lower end of the first door 930
to prevent cool air from leaking between the first door 930 and the
