Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning units for clean operating rooms, and particularly relates to an automatic cleaning air conditioning unit for clean operating rooms. Background Art

[0002] During the use of the air conditioning unit for the clean operating room, it is necessary to absorb air from the outside world. After disinfection and purification, the air is transported into the room. In the prior art, when the outside air passes through the air conditioning unit, the filter screen arranged at the air inlet filters the air. After a period of use, a large amount of dust and impurities will accumulate on the filter screen, thus blocking the filter screen and affecting the overall working efficiency of the air conditioning unit. Therefore, the filter screen needs to be cleaned or replaced frequently. Replacing the filter screen will increase the use cost and maintenance cost of the air conditioning unit. Cleaning the filter screen requires disassembling the machine, which is relatively complicated and very labor-consuming, and will also increase the maintenance cost of the air conditioning unit.

[0003] Chinese Utility Model Patent CN213760931U provides an air conditioning unit capable of automatically cleaning dust. This technical solution uses atomizing nozzles to atomize and clean the impurities on the filter screen, and the water flow generated by atomization is collected and processed through a water receiving tray arranged inside the machine shell. This solution avoids the handling of the air conditioning unit and saves water resources; however, the impurities have already adhered to the filter screen and dried up, and simply relying on atomizing cleaning cannot clean the impurities thoroughly. Secondly, collecting the cleaned water through the water receiving tray will cause bacteria to breed inside the machine shell, endangering physical health. Chinese Utility Model Patent CN220187050U provides an air conditioning unit capable of automatically cleaning dust. This technical solution uses a brush to sweep the impurities on the filter screen, and the swept impurities are collected through a collecting device. This method avoids the pollution and adhesion that may be caused by water washing; however, simply using a brush is difficult to clean the dust and impurities completely, and over time, the filter screen will still be blocked, affecting the working efficiency of the air conditioning unit.
