Description

STOREHOUSE

The present disclosure relates to a storehouse.

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.

An embodiment of the present disclosure aims to provide a storehouse in which a first storage space configured to provide a space in which goods are stored is fluidly connected to a second storage space configured to provide a space in which a first heat exchanger is accommodated.

An embodiment of the present disclosure aims to provide a storehouse including a heat exchanger case forming a second wall and in which a first heat exchanger is installed.

An embodiment of the present disclosure aims to provide a storehouse in which, when a heat exchange device is mounted on a storehouse body, a gap between the heat exchange device and the storehouse body is maintained to facilitate the mounting, and after the heat exchange device is coupled to the storehouse body, the heat exchange device is installed in the storehouse body. The sealing effect can be improved by bringing the heat exchange device into close contact with the storehouse body.

An embodiment of the present disclosure aims to enable sealing of the heat exchange device by moving the heat exchange device toward the storehouse body so as to be in close contact with the storehouse body. For example, the heat exchange device may be in close contact with the storehouse body through a lift device.

An embodiment of the present disclosure aims to provide a storehouse in which a coupling portion of a heat exchange device to a storehouse body can be formed at an appropriate position so as not to interfere with a fluid suction/discharge port.

The screw portion may pass through the support plate, and the support plate may move in the longitudinal direction of the screw portion.

When the support plate moves, the heat exchanger case supported by the support plate may move together with the support plate to come into contact with the storehouse body.

Since the heat exchanger case is in close contact with the storehouse body, the inner space of the heat exchanger case may be sealed to the outside of the storehouse body. Accordingly, the fluid generated in the heat exchanger case may be supplied to the storehouse body without leakage.

As an example, the worm gear assembly may be provided at the lower end portion of the storehouse.
