Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a refrigeration device. Background Art

[0002] Refrigeration equipment is a kind of refrigeration equipment that maintains a constant low temperature, and is also an appliance that keeps food or other items in a constant low temperature cold state. With the development of science and technology and the improvement of people's living standards, refrigerators have become an indispensable appliance in life and production.

[0003] Take refrigerators as an example. Refrigerator is usually equipped with evaporator and condenser. Condenser is used to release heat from external environment to obtain cold. Evaporator is used to release cold into refrigerator to complete refrigeration.

After years of use, dust in the air will accumulate on the condenser surface, greatly reducing the heat exchange efficiency of the condenser. When the heat dissipation effect of the condenser is reduced, the condensation temperature of the refrigerator will rise, increasing the power consumption of the refrigerator. Utility Model Content

The low-temperature and high-pressure liquid refrigerant is converted into a low-temperature and low-pressure liquid refrigerant through the throttling and decompression effect of the throttling device. The low-temperature and low-pressure liquid refrigerant is transported to the evaporator and heat exchanged with the air in the refrigeration air duct.

The dust cover 500 is arranged on the rear cover 400, and a through air inlet 410 is opened on the rear cover 400. The dust cover 500 is detachably connected to the rear cover 400 and covers the air inlet 410. The arrangement of the dust cover 500 ensures that the gas can enter the compressor chamber 110 through the dust cover 500, and on the basis of ensuring air convection, the dust cover 500 can also prevent dust from entering the compressor chamber 110, effectively preventing dust from accumulating on the condenser 320. At the same time, the dust cover 500 is detachable, so that the dust cover 500 is convenient to be removed from the rear cover 400, thereby facilitating the replacement of the dust cover 500 and the cleaning after removal.
