Abstract

The invention discloses a self-cleaning control method and device for an air conditioner, and belongs to the technical field of self cleaning of air conditioners. The control method comprises the steps that when the air conditioner operates in a first frosting mode and meets a first frosting completion condition, the air conditioner is controlled to operate in a first defrosting mode; when operation time of the first defrosting mode meets defrosting time, the air conditioner is controlled to operate in a second frosting mode; and if a second frosting completion condition is met, the air conditioner is controlled to operate in a second defrosting mode. According to the control method, a two-time continuous frosting and defrosting self-cleaning process is adopted, the time for first-time defrosting is set within the specified defrosting time, and therefore condensed water which is melted in the first-time defrosting process can flow to deep-layer parts such as fin gaps, and the condensed water cannot completely break away from a heat exchanger; frost condensation and dust stripping of the condensed water at positions such as the fin gaps is achieved by means of second-time frosting, the overall cleaning effect of the air conditioner is improved, and accumulation of dust at the deep-layer parts of the heat exchanger is reduced.

Description

technical field [0001] The invention relates to the technical field of self-cleaning of air conditioners, in particular to a control method and device for self-cleaning of air conditioners. Background technique [0002] When the indoor unit of the air conditioner is running in cooling or heating mode, the air in the indoor environment enters the interior of the indoor unit along the air inlet of the indoor unit, and is blown back into the indoor environment through the air outlet after the heat exchange fins exchange heat. During this process, impurities such as dust and large particles in the indoor air will also enter the indoor unit with the air intake, although the dust filter installed at the air inlet of the indoor unit can filter most of the dust and particles , but there will still be a small amount of tiny dust that cannot be completely blocked and filtered. With the long-term use of the air conditioner, these dusts will gradually deposit and adhere to the surface o...
