CROSS-REFERENCE TO RELATED PATENT APPLICATIONS
[0001] This application is a continuation of U.S. patent application Ser. No. 18/577,370, filed Jan. 8, 2024, which is a U.S. National Stage Application under 35 U.S.C. § 371 of PCT Application No. PCT/KR 2022/009796, filed Jul. 6, 2022, which claims priority to Korean Patent Application No. 10-2021-0089690, filed Jul. 8, 2021, whose entire disclosures are hereby incorporated by reference.
TECHNICAL FIELD
[0002] The present disclosure relates to a storehouse.
BACKGROUND ART
[0003] A storehouse may include a storage space for storing goods. Examples of the storehouse may include a refrigerator.
[0004] The refrigerator is an apparatus that cools objects to be cooled (e.g., food, drugs, and cosmetics) (hereinafter referred to as food for convenience), or stores food at low temperature so as to prevent spoilage and deterioration. The refrigerator includes a storage space in which food is stored, and a refrigeration cycle part that cools the storage space.
[0005] The refrigeration cycle part may include a compressor, a condenser, an expansion mechanism, and an evaporator, through which a refrigerant circulates.
[0006] A refrigerator according to the related art may include an outer case, and an inner case located inside the outer case and having an opened front side. Such a refrigerator may include a cold air discharge duct disposed inside the inner case to partition the inside of the inner case into a storage space and a heat exchange space. For example, the storage space may be defined in front of the cold air discharge duct, and the heat exchange space may be defined in the rear of the cold air discharge duct. An evaporator and an evaporating fan may be disposed in the heat exchange space.
[0007] The refrigerator may have a separate machine space defined outside the inner case. A compressor, a condenser, and a condensing fan may be disposed in the machine space. The compressor in the machine space may be connected to the evaporator in the heat exchange space through a refrigerant pipe.
[0008] The storage space may be provided with a withdrawable drawer. A plurality of the drawers may be provided in a vertical direction.
[0009] However, the refrigerator according to the related art as described above has the following problems.
[0010] First, the compressor in the machine space and the evaporator in the inner case are disposed in spaces separated from each other and are connected to each other by the refrigerant pipe. Therefore, when it is necessary to repair the refrigeration cycle part, it is inconvenient to take out food stored in the refrigerator so as to check and repair failure.
[0011] Second, since the evaporator has to be integrally formed inside the refrigerator body and the evaporator has to be fixed to the refrigerator body by welding or the like, there is an inconvenience in manufacturing the refrigerator. In addition, when the evaporator defrosts, heat exchange with the storage space increases the internal temperature of the refrigerator.
[0012] Third, since the heat exchange space is disposed in the rear of the storage space, the width of the rear wall of the refrigerator body in the front-and-rear direction increases as much as the size of the heat exchange space. Therefore, the volume of the storage space is reduced as much.
[0013] In order to solve these problems, a refrigerator including a cooling module that integrally configures a heat absorbing portion and a heat dissipating portion has been proposed.

The first storage space may include at least one of a partition wall, a drawer, and a shelf so as to form the plurality of storage compartments. A passage through which a fluid flows may be provided between the plurality of storage compartments.
[0197] An embodiment capable of reducing heat exchange between the defrosting heat source or the steam removing cold source and some of the plurality of storage compartments is as follows. In this manner, when the storehouse is provided as a refrigerator, cooling efficiency may be improved, and when the storehouse is provided as a heating cabinet, heating efficiency may be improved.
[0198] First, one of the plurality of storage compartments may include a surface that faces the second storage space and a surface that faces another one of the plurality of storage compartments.
[0199] One of the plurality of storage compartments may be disposed between the second storage space and another one of the plurality of storage compartments.

[0203] Fourth, the fluid inside the first storage compartment among the plurality of storage compartments may be provided to flow into the second storage space without passing through another one of the plurality of storage compartments, and the fluid inside the second storage compartment among the plurality of storage compartments may be provided to flow into the second storage space through another one of the plurality of storage compartments.
[0204] An embodiment in which the second storage space and the third storage space are disposed is as follows.
[0205] First, the first storage space may include a portion extending in a horizontal direction, i.e., X-axis direction, and a portion extending in a vertical direction, i.e., Y-axis direction. The second storage space may be disposed adjacent to the third storage space in the X-axis direction. A wall partitioning the second storage space and the third storage space may include a portion extending in the Y-axis direction.
[0206] Second, the first storage space may include a portion extending in a horizontal direction, i.e., X-axis direction, and a portion extending in a vertical direction, i.e., Y-axis direction.

A wall partitioning the second storage space and the third storage space may include a portion extending in the X-axis direction.
[0207] An embodiment in which the first heat exchanger and the fluid generator are disposed is as follows.
[0208] First, the first heat exchanger may include a long portion extending in the X-axis direction and a short portion extending in the Y-axis direction, and the fluid generator may be disposed such that a length in the X-axis direction is longer than a length in the Y-axis direction.
[0209] The fluid generator may be disposed spaced apart from the first heat exchanger in the Y-axis direction.
[0210] For example, the fluid generator may be disposed above or below the first heat exchanger.
[0211] The fluid generator may be disposed to overlap the first heat exchanger in the Y-axis direction. The fluid generator may be disposed in an inclined direction with respect to the ground.
[0212] A suction hole through which the fluid is sucked into the first heat exchanger may be disposed to be lower than a discharge hole through which the fluid heat-exchanged with the first heat exchanger is discharged.
[0213] In this manner, the effect of reducing the flow loss of the fluid generator may be obtained.
[0214] Second, the first heat exchanger may include a long portion extending in the X-axis direction and a short portion extending in the Y-axis direction, and the fluid generator may be disposed such that a length in the X-axis direction is shorter than a length in the Y-axis direction.
[0215] The fluid generator may be disposed spaced apart from the first heat exchanger in the X-axis direction. For example, the fluid generator may be disposed in the front or rear of the first heat exchanger. The fluid generator may be disposed to overlap the first heat exchanger in the X-axis direction.

The imaginary line may be disposed to pass through the peripheral portion of the first heat exchanger.
[0218] Second, an imaginary line extending from the center of the fluid generator toward the first storage space may be disposed to pass through the first storage space. An imaginary line extending from the center of the fluid generator toward the first heat exchanger may be disposed so as not to overlap the first heat exchanger.
[0219] Third, the fluid generator may be disposed inside the second storage space. In this case, the first heat exchanger and the fluid generator may be disposed inside the second storage space, which may be advantageous in designing a module for the second storage space. At least a part of the second passage may be provided to be exposed to the second storage space.
[0220] Fourth, the fluid generator may be disposed in at least one of the inside of the first passage and the inside of the second passage. In this case, since the distance between the first heat exchanger and the fluid generator may be separated, there is an advantage that can reduce a dead zone that may occur in the flow passage of the fluid. The passage on which the fluid generator is disposed may include a portion protruding toward the first storage space. Therefore, the volume of the first storage space may be increased. The fluid generator may be disposed inside the protruding portion.
[0221] Fifth, at least a part of the fluid generator may be provided to form at least a part of the first passage or at least a part of the second passage. For example, the fluid generator may include a fan and a fan housing.

[0415] The plurality of through holes may include first through holes 216a and 216b through which the hot line pipe 260 passes. The first through holes 216a and 216b may include one through hole 216a through which one side of the hot line pipe 260 passes and other through hole 216b through which the other side of the hot line pipe 260 passes.
[0416] The one through hole 216a and the other through hole 216b may be defined on different surfaces of the heat exchanger case 200.
[0417] The one through hole 216a may be defined in the case side portion 210b, and the other through hole 216b may be defined n the case front portion 210c.

[0422] The case bottom portion 210f may be supported by the support wall 133.
[0423] The case bottom portion 210f may be inclined downward toward the drain hole 208. For example, the case bottom portion 210f may be inclined downward to the rear.
[0424] Correspondingly, the support wall 133 may be inclined downward in a direction toward the drain hole 208. The support wall 133 may be inclined downward to the rear.
[0425] The case bottom portion 210f may extend rearward from the lower end portion 210a1 (front lower end portion) of the case front portion 210a and may be connected to the case rear portion 210d.
[0426] The case bottom portion 210f may include a bottom inclined portion 210f2 extending downward from the front lower end portion 210a1 to the rear.
[0427] The case bottom portion 210f may include a bottom lower end portion 210f1 extending rearward from the bottom inclined portion 210f2 and connected to the case rear portion 210d.
[0428] The bottom lower end portion 210f1 may include a flat surface.
[0429] The drain hole 208 may pass through the bottom lower end portion 210f1.
[0430] The bottom lower end portion 210f1 may be formed at a lower position than the front lower end portion 210a1.
[0431] When the heat exchanger case 200 is coupled to the partition wall 50 in a state where the case bottom portion 210f is supported by the support wall 133, the heat exchanger case 200 may move upward.
[0432] The heat exchanger case 200 may be in a state of being spaced upward apart from the fluid collecting surface of the tray 130 by the support wall 133. Therefore, the heat exchanger case 200 may not be submerged in the condensed fluid collected in the tray 130.
[0433] The drain hole 208 may be located at the center with respect to the left-and-right direction of the heat exchanger case 200. When the center line (
0) that bisects the heat exchanger case 200 to the left and right is defined, the center line (
0) may pass through the drain hole 208.
0) that bisects the heat exchanger case 200 to the left and right is defined, the center line (0) may pass through the drain hole 208.[0434] Based on the center line (
0), the heat exchanger case 200 may be bilaterally symmetrical.
0), the heat exchanger case 200 may be bilaterally symmetrical.[0435] The drain hole 208 may be configured by combining a first hole defining portion 208a provided in the inner case 212 of the heat exchanger case 200 and a second hole defining portion 208b provided in the outer case 211.
[0436] The bottom portion 207 of the heat exchanger case 200 may be inclined downward from the edge toward the center.
[0437] The drain hole 208 may be defined in the center of the bottom portion 207.
[0438] Based on FIG. 11 (based on the left-and-right direction of the heat exchanger case), the bottom portion 207 may include a first bottom portion 207a extending obliquely downward from the left end edge toward the center by a first predetermined angle (θ1), and a second bottom portion 207b extending downward from the right end edge toward the center by a second predetermined angle (θ2).
[0439] The first predetermined angle (θ1) and the second predetermined angle (θ2) may have the same value. For example, the first and second predetermined angles (θ1 and θ2) may be in a range of 7° to 10°.
[0440] Since the first predetermined angle (θ1) and the second predetermined angle (θ2) have the same value, the first and second bottom portions 207a and 207b may be symmetrical left and right about the drain hole 208, and the thickness of the lower heat insulating wall of the heat exchanger case 200 may be formed evenly based on the drain hole 208.
[0441] As another example, the first predetermined angle (θ1) and the second predetermined angle (θ2) may have different values. However, even in such a case, the first and second predetermined angles (θ1 and θ2) may be in a range of 7° to 10°.
[0442] As described above, since the bottom portion 207 is inclined downward toward the drain hole 208, the condensed fluid collected in the bottom portion 207 can be easily discharged into the drain hole 208.
[0443] Based on FIG. 13 (based on the front-and-rear direction of the heat exchanger case), the bottom portion 207 may include a first inclined portion 207c extending downward from the front edge by a third predetermined angle (θ3) in a direction (rearward) closer to the drain hole 208, and a second inclined portion 207d extending downward from the first inclined portion 207c toward the drain hole 208 by a fourth predetermined angle (θ4).
[0444] The first inclined portion 207c may be defined below the first heat exchanger 220.
[0445] The second inclined portion 207d may be located closer to the fan assembly 300 than the first inclined portion 207c.
[0446] The drain hole 208 may be defined closer to the center of the fan assembly 300 than the center of the first heat exchanger 220.
[0447] In order to further secure a space in which the fan assembly 300 is installed, the fourth predetermined angle (θ4) may be greater than the third predetermined angle (θ3). That is, since the fourth predetermined angle (θ4) is relatively great, the space of the case accommodation portion 205 defined above the second inclined portion 207d can be formed to be large.
[0448] Since the fourth predetermined angle (θ4) is greater than the third predetermined angle (θ3), the condensed water generated in the first heat exchanger 220 may be easily discharged to the drain hole 208 without reducing the flow rate while passing through the first inclined portion 207c and the second inclined portion 207d.
[0449] However, although the fourth predetermined angle (θ4) is greater than the third predetermined angle (θ3), the third and fourth predetermined angles (θ3 and θ4) may be in a range of 7° to 10°.
[0450] Based on FIG. 13 (based on the front-and-rear direction of the heat exchanger case), the bottom portion 207 may further include a third inclined portion 207e extending downward from the rear edge toward the drain hole 208 by a fifth predetermined angle (θ5).
[0451] Since the uppermost end of the third inclined portion 207e is located lower than the uppermost end of the first inclined portion 207c or the uppermost end of the second inclined portion 207d, a large space in which the fan assembly 300 is installed can be secured.
[0452] The fifth predetermined angle (θ5) may have the same value as the third predetermined angle (θ3).
[0453] The fifth predetermined angle (θ5) may have a smaller value than the fourth predetermined angle (θ4).
[0454] The fifth predetermined angle (θ5) may be in a range of 7° to 10°.
[0455] The first to fifth setting angles may be determined as appropriate values in consideration of the thickness of the case insulating material 213 of the heat exchanger case 200, the depth of the drain hole 208, and the arrangement of the first heat exchanger 220 and the fan assembly 300.
[0456] The SLHX 270 and the hot line pipe 260 may be provided in the heat exchanger case 200.
[0457] The heat exchanger case 200 includes an outer case 211 defining an outer surface and an inner case 212 disposed inside the outer case 211.
[0458] The outer case 211 may have a hexahedral shape with an opened upper end.
[0459] The inner case 212 may have a hexahedral shape with an opened upper end.
