Description

Storage room

Technical Field

The present disclosure relates to a storage compartment.

Background

The storage compartment may include a storage space for storing the articles. Examples of the storage chamber may include a refrigerator.

A refrigerator is a device that cools objects to be cooled (e.g., foods, medicines, and cosmetics) (hereinafter, referred to as foods for convenience) or stores foods at low temperature to prevent spoilage and deterioration. The refrigerator includes a storage space to store food and a refrigerating cycle part to cool the storage space.

The refrigeration cycle 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 open front side. Such a refrigerator may include a cool air discharge duct provided at the inside of the inner case to divide 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 rear of the cold air discharge duct. The evaporator and the evaporation fan may be disposed in the heat exchange space.

The refrigerator may have a separate machine space defined outside the inner case. The compressor, condenser and 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 by means of refrigerant pipes.

The storage space may be provided with a drawer that is extractable. A plurality of drawers may be provided in a vertical direction.

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

First, a compressor in a machine space and an evaporator in an inner case are disposed in a space separated from each other and connected to each other by a refrigerant pipe. Therefore, when it is necessary to repair the refrigeration cycle, the food stored in the refrigerator is taken out to check and repair the malfunction, which is inconvenient.

Second, since the evaporator must be integrally formed inside the refrigerator body and the evaporator must be fixed to the refrigerator body by welding or the like, there is an inconvenience in manufacturing the refrigerator. In addition, when the evaporator is defrosted, heat exchange with the storage space increases the internal temperature of the refrigerator.

Third, since the heat exchange space is provided at the rear of the storage space, the width of the rear wall of the refrigerator body in the front-rear direction may increase with the size of the heat exchange space. Accordingly, the volume of the storage space is also reduced accordingly.

In order to solve these problems, a refrigerator including a cooling module integrally constructing a heat absorbing part and a heat dissipating part has been proposed.
