chamber door 145. The accommodation portion 147 may be integrally
formed with the freezing chamber door 145. The accommodation
portion 147 may be formed to have a height lower than that of the
freezing chamber 140. A drawer 160 may be provided at an inner
upper region of the freezing chamber 140 so as to be withdrawn in
back and forth directions.
[0053] The drawer 160 may be formed in an upwardly-opened box
shape, and may be configured to have a width in right and left
directions corresponding to a width of the freezing chamber 140 in
right and left directions. Sliding supporting portions 163
configured to slidably support the drawer 160 may be provided at
both side walls of the freezing chamber 140. In the preferred
embodiment, the sliding supporting portions 163 are implemented as
rails 163. Alternatively, the sliding supporting portions 163 may
be implemented by providing a roller (not shown) at the drawer 160,
and by providing a roller supporting portion configured to support
motion of the roller, at side walls of the freezing chamber 140
and/or an upper end of the accommodation portion 147.
[0054] The connecting member 170 configured to slide the freezing
chamber door 145 and the drawer 160 in an interworking manner with
each other may be provided between the freezing chamber door 145
and the drawer 160. More concretely, when the freezing chamber door
145 is withdrawn, the drawer 160 may be pulled by the connecting
member 170 to be withdrawn together with the freezing chamber door
145. Accordingly, the freezing chamber door 145 and the drawer 160
may be simultaneously opened by one operation to open the freezing
chamber door 145.
[0055] The connecting member 170 may be provided at the freezing
chamber door 145.
[0056] As shown in FIGS. 3 and 4, the connecting member 170 may
include a body 171 having one end connected to the freezing chamber
door 145, and a hooking portion 181 formed to be bent at another
end of the body 171.
[0057] The body 171 may be formed in a rectangular plate shape. A
hinge pin 175 may be provided at one end of the body 171. The hinge
pin 175 may be implemented in plurality in number. Each of the
hinge pins 175 may have one end connected to the body 171, and
another end formed to be bent.
[0058] The connecting member 170 may be coupled to an upper central
part of a rear surface of the freezing chamber door 145. A
connecting member supporting portion 151 configured to rotatably
support the connecting member 170 may be formed at the freezing
chamber door 145. The connecting member supporting portion 151 may
be provided with hinge pin holes 152 formed at both ends thereof so
as to rotatably insert the hinge pins 175 thereinto.
[0059] The connecting member 170 may be coupled to the connecting
member supporting portion 151 so that the hooking portion 181 can
be toward the lower side when the body 171 is horizontally
arranged. Since the hooking portion 181 is arranged so as to
contact a rear side of a front surface of the drawer 160, the
hooking portion 181 forwardly pulls the front surface of the drawer
160 when the freezing chamber door 145 is withdrawn. As a result,
the drawer 160 is forwardly withdrawn.
[0060] An insertion portion 155 configured to insert the hooking
portion 181 of the connecting member 170 thereinto may be provided
at a lower side of the connecting member supporting portion 151.
The insertion portion 155 may be implemented as a slot configured
to insert the hooking portion 181 thereinto.
[0061] When the connecting member 170 is not used, the hooking
portion 181 may be inserted into the insertion portion 155 by
downwardly rotating the connecting member 170. Accordingly, the
connecting member 170 is not protruding form a rear surface of the
freezing chamber door 145, but is fixed into the insertion portion
155 not to be moved. This may prevent interference between the
connecting member 170 and the periphery.
[0062] Hereinafter, the operation of the connecting member 170 will
be explained with reference to FIGS. 5 and 6.
[0063] When the freezing chamber door 145 and the drawer 160 are to
be interworked with each other, as shown in FIG. 5, the connecting
member 170 is upwardly rotated to arrange the hooking portion 181
on a rear side of a front surface of the drawer 160. Under this
state, once the freezing chamber door 145 is forwardly pulled to be
withdrawn, the front surface of the drawer 160 is forwardly pulled
by the hooking portion 181. Accordingly, the drawer 160 is
withdrawn to the front side of the freezing chamber 140 in a
sliding manner. This may allow the drawer 160 to be simultaneously
forwardly withdrawn when the freezing chamber door 145 is opened,
without requiring to forwardly withdraw the drawer 160 after
opening the freezing chamber door 145.
[0064] On the contrary, when only the freezing chamber door 145 is
to be withdrawn while the drawer 160 maintains an accommodated
state in the freezing chamber 140, as shown in FIG. 6, the
connecting member 170 is upwardly rotated to separate the hooking
portion 181 from the drawer 160. Then, the connecting member 170 is
downwardly rotated to contact the body 171 to a rear surface of the
freezing chamber door 145. Since the hooking portion 181 is in an
accommodated state in the insertion portion 155, interference of
the connecting member 170 with the periphery may be prevented.
Under this state, once the freezing chamber door 145 is forwardly
pulled to be withdrawn, only the freezing chamber door 145 is
forwardly withdrawn while the drawer 160 maintains an accommodated
state in the freezing chamber door 140.
[0065] Hereinafter, a refrigerator according to another embodiment
of the present invention will be explained in more detail with
reference to FIGS. 7 to 10.
[0066] FIG. 7 is an enlarged sectional view showing main parts of a
refrigerator according to another embodiment of the present
invention, FIG. 8 is a perspective view of a region of the
connecting member of the refrigerator of FIG. 7, FIG. 9 is a view
to explain the operation of a connecting member of FIG. 7, and FIG.
10 is a view showing a state that a freezing chamber door of FIG. 7
has opened.
[0067] The same or similar parts as/to those of the aforementioned
embodiment will be provided with no reference numerals for
convenience, and explanations thereof will be omitted.
[0068] As shown in FIGS. 7 and 8, the refrigerator according to
another embodiment of the present invention comprises: a
refrigerator body 110 having a refrigerating chamber 130 and a
freezing chamber 140 partitioned from each other by a partition
wall 120; a freezing chamber door 145 configured to open and close
the freezing chamber 140 by performing a sliding motion with
respect to the refrigerator body 110; a drawer 190 accommodated in
the freezing chamber 140 so as to be withdrawn in a sliding manner;
and a connecting member 210 configured to connect the freezing
chamber door 145 and the drawer 190 to each other.
[0069] An accommodation portion 147 configured to accommodate food
items therein may be formed on a rear surface of the freezing
chamber door 145. The accommodation portion 147 may be formed to
have a height lower than that of the freezing chamber 140. A drawer
190 may be installed above the accommodation portion 147 in the
freezing chamber 140.
[0070] The drawer 190 may include a plurality of horizontal wires
192 disposed in a horizontal direction, and a plurality of vertical
wires 194 disposed in a vertical direction. The drawer 190 may be
formed in an approximate box shape having an opened upper side.
[0071] The connecting member 210 may be provided at the drawer 190.
Alternatively, the connecting member 210 may be provided at a front
surface of the drawer 190. Still alternatively, the connecting
member 210 may be detachably coupled to the drawer 190.
[0072] The connecting member 210 may include a body 211 having one
end coupled to the drawer 190, and a hooking portion 221 formed to
be bent at another end of the body 211. A length and a width of the
body 211 may be properly controlled.
[0073] At one end of the body 211, may be formed a wire coupling
portion 213 having one opened side so as to be detachably coupled
to the horizontal wires 192 or the vertical wires 194. A sectional
surface of the wire coupling portion 213 may be formed in a
circular ring shape having one opening 214.
[0074] The wire coupling portion 213 may be formed of an elastic
member (e.g., synthetic resin member) which is elastically
transformed so that the opening 214 can be outwardly widened when
coupling the wires to the wire coupling portion 213 or when
detaching the wires from the wire coupling portion 213.
[0075] Sizes of the wire coupling portion 213 and the opening 214
may be formed to correspond to diameters of the horizontal wires
192 or the vertical wires 194. In the preferred embodiment, the
connecting member 210 is coupled to the horizontal wires 192 so as
to be rotatable in upper and lower directions, the horizontal wires
192 horizontally arranged at an upper part of a front surface of
the drawer 190.
[0076] A contact portion 230 configured to couple the hooking
portion 221 of the connecting member 210 thereto, and to maintain
the coupled state in back and forth directions may be provided at a
rear surface of the freezing chamber door 145.
[0077] The contact portion 230 may be implemented as a hook ring
230 protruding from a rear surface of the freezing chamber door
145. The hook ring 230 may be formed in a `U` shape. Alternatively,
the contact portion 230 may be implemented as a recess concavely
formed at an upper surface of a protrusion so that the hooking
portion 221 can be inserted thereinto by a predetermined depth from
an upper side to a lower side, the protrusion formed at a rear
surface of the freezing chamber door 145.
[0078] Hereinafter, the operation of the connecting member will be
explained with reference to FIGS. 9 and 10.
[0079] When the drawer 190 is to be interworked with the freezing
chamber door 145, as shown in FIG. 9, the connecting member 210 is
upwardly rotated, thereby coupling the hooking portion 221 of the
connecting member 210 to the contact portion 230 of the freezing
chamber door 145. Accordingly, the drawer 190 is interworked with
the freezing chamber door 145 to be in a slidable state. Once the
freezing chamber door 145 is forwardly pulled, the force applied to
the freezing chamber door 145 is transmitted to the drawer 190 by
the connecting member 210. Accordingly, the drawer 190 is withdrawn
to the front side.
[0080] When the interworked state between the drawer 190 and the
freezing chamber door 145 is to be released, as shown in FIG. 10,
the connecting member 210 is upwardly rotated, thereby detaching
the hooking portion 221 of the connecting member 210 from the
contact portion 230 of the freezing chamber door 145.
[0081] The detached connecting member 210 is downwardly rotated
with respect to the wires due to its self weight, thereby being in
a vertical direction. Under this state, once the freezing chamber
door 145 is forwardly pulled, only the freezing chamber door 145 is
forwardly withdrawn while the drawer 190 is in an accommodated
state in the freezing chamber 140.
[0082] In the present invention, the freezing chamber door is
configured to be slidable, and the drawer is provided in the
freezing chamber. However, the refrigerating chamber door may be
configured to be slidable, and the drawer may be provided in the
refrigerating chamber.
[0083] In the present invention, one drawer is formed in the
freezing chamber. However, the drawer may be formed in plurality in
number, and the plurality of drawers may be configured to be
interworked with the freezing chamber door by the connecting
member.
[0084] In the present invention, the accommodation portion of the
freezing chamber door, and the drawer are arranged in upper and
lower directions. However, the accommodation portion of the
freezing chamber door, and the drawer may be spacing from each
other in right and left directions.
[0085] In the preferred embodiment with reference to FIGS. 7 to 10,
the connecting member is coupled to the horizontal wires of the
drawer. However, the connecting member may be coupled to the
vertical wires of the drawer.
[0086] As aforementioned, in the present invention, since the
connecting member is configured to connect the door and the drawer
to each other, the drawer is withdrawn when the door is withdrawn.
This may enhance a user's convenience.
[0087] Furthermore, since the door is configured to be selectively
interworked with the drawer, the door and the drawer are
interworked with each other when using the drawer, while the door
and the drawer are separately operated from each other when not
using the drawer. This may also enhance a user's convenience.
[0088] The foregoing embodiments and advantages are merely
exemplary and are not to be construed as limiting the present
disclosure. The present teachings can be readily applied to other
types of apparatuses. This description is intended to be
illustrative, and not to limit the scope of the claims. Many
alternatives, modifications, and variations will be apparent to
those skilled in the art. The features, structures, methods, and
other characteristics of the exemplary embodiments described herein
