Description

Technical Field

[0001] The present application belongs to the technical field of refrigerators, and specifically relates to a cold storage refrigerator. Background Art

[0002] A cold storage refrigerator is a device used for cooling and maintaining low temperatures. It is usually used in food, medicine, chemical and other industries. It transfers heat from the inside of the cold storage to the outside through the circulation of refrigerant, thereby achieving the purpose of cooling and maintaining low temperatures. A cold storage refrigerator is usually composed of a compressor, condenser, expansion valve and evaporator. The compressor compresses the refrigerant into a high-temperature and high-pressure gas, and then dissipates the heat to the outside through the condenser. The refrigerant is cooled into a liquid, and the expansion valve expands the liquid refrigerant into a low-temperature and low-pressure gas, and then absorbs the heat inside the cold storage through the evaporator. The refrigerant evaporates into a gas again, and the cycle repeats to achieve the purpose of cooling and maintaining low temperatures.

[0004] However, it was found during actual use that when the filter of the device is clogged, personnel are required to manually clean the filter, which increases the workload and requires personnel to pay special attention to the condition of the filter. This method is not convenient enough and cannot effectively reduce the workload of personnel. Therefore, a cold storage refrigeration machine is provided. Utility Model Content
