Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority under 35 U.S.C. .sctn.119
to Korean Patent Application No. 10-2015-0022647, filed in Korea on
Feb. 13, 2015, whose entire disclosure is incorporated herein by
reference.
BACKGROUND
[0002] 1. Field
[0003] Embodiments relate to a refrigerator.
[0004] 2. Background
[0005] As refrigerators become larger, storage compartments in the
refrigerators become deeper, and a separate storage space may be
provided at a rear surface of the refrigerators doors. According to
Korean Patent Publication No. 2010-0122155 published on Nov. 22,
2010, which has been filed by the applicant and incorporated by
reference herein, a door that opens and closes a storage
compartment in a refrigerator may have a structure including an
inner door and an outer door. A housing, which defines an
accommodation space, may be installed at a rear surface of the
inner door, which is in close contact with a cabinet. An opening,
which allows access to an inside of the housing, may be formed at
the inner door, and the opening may be blocked by the outer
door.
[0006] A user may store items, e.g., food, which used, in the
housing, and thus, may take out food stored in the housing by
opening only the outer door and may also minimize leakage of cool
air from the storage compartment. However, when food is
accommodated in the housing, the cool air in the storage
compartment of the refrigerator may not be smoothly supplied into
the housing. Food accommodated in the housing may serve as an
obstacle that blocks flow of the cool air, and thus, the cool air
supplied into the housing may not circulate.
[0007] To solve the above-described problems, a method, in which a
duct connecting an evaporation compartment with the housing is
separately installed inside the cabinet of the refrigerator, has
been proposed. However, a disadvantage for this method is that a
separate duct component may be installed at a side surface or an
upper surface of the cabinet, and a separate insulation for the
duct may be required. Thus, an insulating effect of the duct may be
lowered, dew condensation or ice formation may occur, and the duct
may expand during a foaming process.

[0015] When the doors 12, 13 are rotatable, the doors 12, 13 may be
a pair of French doors, which may be rotatably connected to a left
or first edge and a right or second edge of the front surface of
the cabinet 11. At least one of the pair of French doors may
include an inner door 121, which may be rotatably coupled to the
front surface of the cabinet 11, and an outer door 122, which may
be rotatably coupled to the inner door 121 at a front surface of
the inner door 121. The inner door 121 and the outer door 122 may
be referred to as a first door and a second door, respectively.
[0016] FIG. 2 is a rear perspective view of the door of the
refrigerator according to the embodiment. FIG. 3 is a perspective
view of a door basket provided at the door of the refrigerator
according to the embodiment. FIG. 4 is a longitudinal
cross-sectional view taken along line IV-IV of FIG. 1. FIG. 5 is a
cross-sectional view taken along line V-V of FIG. 2. Referring to
FIGS. 2 to 5, the door 12 of the refrigerator 10 may include the
inner door 121, and the outer door 122. The inner door 121 may
include a door case 121a, which may form an external appearance of
the inner door 121, a door liner 121b, which may be installed or
provided at a rear surface of the door case 121a, and a door dike
121c, which may protrude from the door liner 121b at a
predetermined length and may be provided along an outer edge of the
door liner 121b. Referring to FIG. 4, an access hole or an opening
121d having a predetermined size may be formed inside the inner
door 121, and the access hole 121d may be selectively opened and
closed by the outer door 122.
[0017] A housing 14, which may define a food accommodation space,
may be installed or provided at a rear surface of the inner door
121. The housing 14 may be coupled to the door dike 121c. A width
of the food accommodation space formed at the inner door 121 may be
defined as a sum of a length corresponding to a thickness of the
inner door 121 defined by the door case 121a and the door liner
121b, a protruding length of the door dike 121c, and a width of the
housing 14.
[0018] The housing 14 may include upper and lower surfaces, left
and right side surfaces, a rear surface, and an opened front
surface. A size of the opened front surface may correspond to a
size of the access hole 121d. A cool air inlet port 141, through
which cool air may be introduced into the housing 14, may be formed
at the upper surface of the housing 14, and a plurality of cool air
outlet ports 142 may be formed at the rear surface of the housing
14.
[0019] A plurality of basket supporting ribs 143 may protrude from
an inner surface of the housing 14. The plurality of basket
supporting ribs or brackets 143 may be provided inside the housing
14 to be spaced apart from each other vertically at predetermined
intervals. Each of the basket supporting ribs 143 may horizontally
extend from the inner surface of the housing 14 while having a
predetermined width, and may continuously extend along the left and
right side surfaces and the rear surface of the housing 14.
Alternatively, each of the basket supporting ribs 143 may extend
from only inner surfaces of the left and right side surfaces of the
housing 14.
[0020] One or more door baskets 15 may be installed inside the
housing 14. Each of the door baskets 15 may be seated on the basket
supporting ribs 143 and may be coupled to the door dike 121c. The
one or more door baskets 15 may be separably coupled to the door
dike 121c. When the door baskets 15 are coupled to the door dike
121c, a bottom of each of the door baskets 15 may be in contact
with the basket supporting ribs 143. For example, a fastening rib
121e, which may protrude toward a center of the access hole 121d
and vertically extend a predetermined length, may be formed at an
inner surface of the door dike 121c. The fastening rib 121e may be
inserted into a side surface of the door basket 15.
[0021] When the door baskets 15 are installed or provided inside
the housing 14, a cool air path 105, through which the cool air may
pass, may be formed between the front surface of the inner door 121
and front surfaces of the door baskets 15. When the door baskets 15
are installed or provided inside the inner door 121, the front
surfaces of the door baskets 15 are spaced backward apart from the
front surface of the inner door 121 at a predetermined distance.
Therefore, cool air from the refrigerator compartment 111
introduced into the cool air inlet port 141 may flow down along the
cool air path 105, and then may be discharged again into the
refrigerator compartment 111 through the plurality of cool air
outlet ports 142.
[0022] Each of the door baskets 15 may be in a box shape, of which
an upper surface may be opened. For example, each of the door
baskets 15 may include a front portion 152, a rear portion 153, a
left side portion 154 and a right side portion 155, which may
connect ends of the front portion 152 and the rear portion 153, and
a bottom portion 151, which may connect lower ends of the rear
portion 153, the left and right side portions 154 and 155, and the
front portion 152.
[0023] A basket installation part or mount 156 may be formed at
each of left and right edges of the rear portion 153. For example,
the basket installation mount 156 may further protrude from the
rear portion 153. The basket installation mount 156 may be coupled
to the door dike 121c. As the basket installation mount 156
protrudes further than the rear portion 153 of the door basket 15,
a distance L1 from a front end of the basket installation mount 156
to the front portion 152 of the door basket 15 may be longer than a
distance L2 between the rear portion 153 and the front portion
152.
[0024] A fastening groove 157, in which the fastening rib 121e
formed at the door dike 121c may be inserted, may be recessed from
an outer surface of the basket installation mount 156. The
fastening rib 121e may be inserted into the fastening groove 157 in
a direction in which the door basket 15 may be moved onto the
fastening rib 121e, for example, a downward direction, and thus,
the door basket 15 may be coupled to the door dike 121c. As the
fastening rib 121e is inserted into the fastening groove 157 by
moving the door basket 15 downward, the door basket 15 may be
prevented from being separated from the inner door 121 while the
inner door 121 is opened and closed.
[0025] As illustrated in FIGS. 3 and 5, the cool air descending
path 105 may be defined as a space formed by the rear portion 153
of the door basket 15, the basket installation mount 156, the
access hole 121d, and a rear surface of the outer door 122. A
distance from the rear surface of the outer door 122 to the rear
portion 153 of the door basket 15 may be defined as a width of the
cool air descending path 105.
[0026] Referring to FIG. 4, a cool air circulation fan 20 may be
installed or provided at an upper surface of a front portion of the
cabinet 11. For example, the cool air circulation fan 20 may be
located at a position corresponding to just above the cool air
inlet port 141 of the housing 14. A fan seating groove 113 formed
to be recessed at a predetermined depth may be formed at an inner
upper surface of the cabinet 11 at which the cool air circulation
fan 20 may be installed. A wire 114 connected to the cool air
circulation fan 20 may extend along an inside of the cabinet 11,
and may be connected to a controller.
[0027] The cool air circulation fan 20 may be inclined at an angle
corresponding to a gradient of the upper surface of the housing 14.
A bottom of the fan seating groove 113 may be inclined with a
gradient, which is the same as a gradient of the upper surface of
the housing 14. For example, the fan seating groove 113 may be
recessed by a depth, which may accommodate the cool air circulation
fan 20 such that the cool air circulation fan 20 may not interfere
with the upper surface of the housing 14 when the door 12 is
closed. That is, the fan seating groove 113 may be recessed with a
predetermined depth so that a lower surface of the cool air
circulation fan 20 may be spaced apart from the upper surface of
the housing 14 at a predetermined distance when the cool air
circulation fan 20 is installed at a ceiling of the refrigerator
compartment 111.
[0028] Also, the fan seating groove 113 may have a sufficient size
such that the cool air in the refrigerator compartment 111 may be
introduced to the cool air circulation fan 20. That is, when the
door 12 is closed, a rear end of the fan seating groove 113 may be
further rearward than the rear surface of the housing 14. Then, the
cool air in the refrigerator compartment 111 may be suctioned to
the cool air circulation fan 20 through a space defined between the
rear surface of the housing 14 and a rear end of the fan seating
groove 113.
[0029] For example, the cool air suctioned by the cool air
circulation fan 20 may be supplied into the housing 14 through the
cool air inlet port 141 of the housing 14, and the cool air
supplied in the housing 14 may cool food inside the housing 14 in a
refrigerated state. A circulation process, in which the cool air
supplied in the housing 14 may flow down along the cool air
descending path 105 and be discharged again into the refrigerator
compartment 111 through the cool air outlet ports 142, may be
repeated. Thus, as the cool air circulation fan is installed at the
ceiling portion of the storage compartment inside the cabinet, the
cool air in the storage compartment of the refrigerator may be
supplied to the housing of the door, and the cool air may be
smoothly circulated.
[0030] According to the embodiment, there may be no need to lay a
duct structure inside the cabinet, and duct expansion, dew
condensation, or ice formation during a foaming process may be
prevented. Embodiments disclosed herein provide a refrigerator
