Abstract

The present disclosure relates to storehouse.

Description

TECHNICAL FIELD

The present disclosure relates to a storehouse.

BACKGROUND ART

A storehouse may include a storage space for storing goods. Examples of the storehouse may include a refrigerator.

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.

The refrigeration cycle part may include a compressor, a condenser, an expansion mechanism, and an evaporator, through which a refrigerant circulates.

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.

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.

The storage space may be provided with a withdrawable drawer. A plurality of the drawers may be provided in a vertical direction.

However, the refrigerator according to the related art as described above has the following problems.

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.

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.

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.

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.

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.

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.

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.

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. The fan housing may define at least a part of the first passage, or the fan housing may define at least a part of the second passage.

With reference to FIGS. 11 and 12, the arrangement of the heat exchanger 220 and the first and second fan assemblies 231 and 235 will be briefly described.

The heat exchanger 220 may include a front portion 221, a first side portion 222 extending rearward from the left end of the front portion 221, a second side portion 223 extending to the right from the first side portion 222, and a third side portion 224 extending rearward from the second side portion 223.

Due to the configuration of the first to third side portions 222, 223, and 224, the rear portion (second heat exchange part) of the heat exchanger 220 may have a narrower width in the left and right direction than the front portion (first heat exchange part). The rear portion of the heat exchanger 220 may have a laterally recessed shape.

The second fan assembly 235 may be arranged to be spaced apart from the side of the third side portion 224. The distance between the second fan assembly 235 and the third side portion 224 may form a fourth set distance S4.

The distance between the first fan assembly 231 and the fourth side portion 225 may form a fifth set distance S5. For example, the fourth set distance S4 may be formed to be somewhat larger than the fifth set distance S5.

Since the fins of the heat exchanger 220 extend in the front and rear direction, when the second fan assembly 235 and the heat exchanger 220 are too close to each other, Fluid suction into the second fan assembly 235 may not be easy due to high flow resistance. In order to prevent this, the separation distance S4 between the second fan assembly 235 and the heat exchanger 220 may be formed to be relatively large, for example, may be greater than the separation distance S5 between the first fan assembly 231 and the heat exchanger 220.

As shown in FIG. 13, the rear end portion of the second fan assembly 235 is disposed further rear than the rear end portion of the heat exchanger 220, so the fluid passing through the heat exchanger 220 may be easily sucked into assembly 235.
