Description

storehouse {Storehouse}

The present invention relates to storage.

A refrigerator is a device that cools objects to be cooled (hereinafter, referred to as food for convenience) such as foods, medicines, and cosmetics, or stores them at a low temperature to prevent spoilage and deterioration. A refrigerator includes a storage compartment in which food is stored and a refrigerating cycle component for cooling the storage compartment.

Refrigerating cycle parts may include a compressor, a condenser, an expansion mechanism, and an evaporator through which refrigerant is circulated.

A refrigerator according to the prior art may include an outer case and an inner case positioned inside the outer case and having an open front. In such a refrigerator, a cold air discharge duct may be disposed inside the inner case and partition the inside of the inner case into a storage chamber and a heat exchange chamber. For example, a storage chamber may be formed in front of the cold air discharge duct, and a heat exchange chamber may be formed in the rear. An evaporator and an evaporation fan may be disposed in the heat exchange chamber.

In the refrigerator, a separate machine room may be formed outside the inner case, a compressor, a condenser, and a condensation fan may be disposed in the machine room, and the compressor in the machine room may be connected to the evaporator in the heat exchange room through a refrigerant pipe.

A draw-out drawer may be provided in the storage compartment. A plurality of drawers may be provided in a vertical direction.

According to the refrigerator according to the prior art as described above, the following problems appear.

First, since the compressor disposed in the machine room and the evaporator disposed inside the inner case are disposed in a space separated from each other and connected by refrigerant piping, when repair of refrigerating cycle parts is necessary, take out food stored in the refrigerator to check for failure, There are inconveniences that need to be repaired.

Second, since the evaporator is integrally formed inside the refrigerator body and the evaporator must be fixed to the refrigerator body by welding, manufacturing of the refrigerator is cumbersome. Also, when defrosting the evaporator, there is a problem in that the internal temperature of the refrigerator rises due to heat exchange with the storage compartment.

Third, since the heat exchange chamber is disposed at the rear of the storage chamber, the front and rear width of the rear wall of the refrigerator body is increased by the size of the heat exchange chamber, and accordingly, the volume of the storage chamber is reduced accordingly.

In order to solve this problem, a refrigerator equipped with a cooling module integrally constituting a heat absorbing unit and a heat dissipating unit has been proposed.
