Problems solved by technology
[0002] During the long-term use of air-conditioning products, impurities such as dust in the indoor environment will settle on the surface of the indoor unit, and some impurities will enter the internal structure of the indoor unit through the air inlet of the indoor unit, resulting in the coil and heat exchange of the indoor unit. Thick dust accumulates on the fins and other components, which easily hinders the heat exchange between the heat exchanger and the indoor environment, affecting the overall heat exchange efficiency of the indoor unit
[0003] Therefore, some air conditioners

The invention discloses a control method and device for the self-cleaning of an air conditioner indoor unit and belongs to the technical field of air conditioner cleaning. The control method comprises: controlling an air conditioner to run in a refrigerating mode and closing a fan of the indoor unit; detecting the temperature of a coiled pipe of the indoor unit, and controlling the fan to run at a first rotating speed for a first duration when the temperature of the coiled pipe is lower than a frosting critical temperature; and controlling the air conditioner to run in a heating mode, and carrying out defrosting cleaning on the indoor unit. According to the control method, by carrying out refined operation on the fan of the indoor unit, the losses of cold air before the frosting critical temperature is reached can be reduced, the flow of air in the indoor unit can also be accelerated through the running of the fan after the frosting critical temperature is reached, temperature and vapor distribution is uniform, and frosting thickness is even.
Description
technical field [0001] The invention relates to the technical field of air conditioner cleaning, in particular to a control method and device for self-cleaning of an air conditioner indoor unit. Background technique [0002] During the long-term use of air-conditioning products, impurities such as dust in the indoor environment will settle on the surface of the indoor unit, and some impurities will enter the internal structure of the indoor unit through the air inlet of the indoor unit, resulting in the coil and heat exchange of the indoor unit. Thick dust accumulates on the fins and other components, which easily hinders the heat exchange between the heat exchanger and the indoor environment, and affects the overall heat exchange efficiency of the indoor unit. [0003] Therefore, some air conditioners in the prior art can realize self-cleaning of the inside of the indoor unit by using control processes such as condensing and defrosting-heating and defrosting. However, in th...
