Abstract

The invention provides an air conditioner and a self-cleaning control method and control device thereof. The method comprises the following steps: after the air conditioner enters a self-cleaning mode, determining the current self-cleaning stage of the air conditioner, wherein the self-cleaning stage of the air conditioner comprises an icing and frosting stage; when the air conditioner is in the icing and frosting stage, controlling the air conditioner to keep refrigerating operating, wherein a first fan is controlled to stop operating and a second fan is controlled to operate, and then the first fan is controlled to operate and the second fan is controlled to stop operating. Therefore, the problem of excessive system pressure caused by shutting down both the first fan and the second fan in the icing and frosting stage can be effectively avoided; and meanwhile, the frosting time of the lower part of an indoor heat exchanger can also be shortened.

Description

technical field [0001] The present invention relates to the technical field of household electrical appliances, in particular to an air conditioner self-cleaning control method, an air conditioner self-cleaning control device, an air conditioner and a computer-readable storage medium. Background technique [0002] When the air conditioner is not used for a long time, there will be a large amount of dust accumulation, dust and other impurities deposited on the heat exchanger will cause the heat exchanger to be dirty and blocked, resulting in a decrease in heat transfer, and the heat transfer performance of the air conditioner will drop significantly, affecting User experience. [0003] In the related art, the heat exchanger is cleaned by running the air conditioner in a cooling mode so that frost forms on the surface of the heat exchanger. However, the problems in the related technology are that the cleaning is not thorough enough, the cooling time is not reasonable enough, ...
