Self-cleaning method and device for air conditioner, air conditioner and electronic device

Abstract

The invention discloses a self-cleaning method and device for an air conditioner, the air conditioner and an electronic device. The self-cleaning method comprises the steps that a self-cleaning instruction for the air conditioner is responded, and a refrigeration and frosting stage is started; the situation that the air conditioner meets the ending condition of the refrigeration and frosting stageis recognized, a compressor in the air conditioner is controlled to be stopped for a preset time length, and an indoor fan is maintained to rotate in the compressor stopping process; and the air conditioner is controlled to enter a heating and defrosting stage. According to the method, before the air conditioner is controlled to enter the heating and defrosting stage, the compressor can be controlled to be stopped, and the problem that the air conditioner is damaged due to the fact that the high-low pressure difference is too large due to switching of the refrigeration and heating modes of the air conditioner can be avoided; and the indoor fan is maintained to rotate in the compressor stopping process, thus, an indoor heat exchanger is defrosted in advance through indoor air with the hightemperature, a heat source can be effectively utilized, the operation time length of the defrosting stage can be shortened, and then the waiting time of a user is shortened.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner self-cleaning method and device, an air conditioner, electronic equipment and a computer-readable storage medium. Background technique [0002] After the air conditioner is used for a long time, a large amount of dirt will adhere to the heat exchanger, resulting in dust on the outer surface of the heat exchanger, which will reduce the heat exchange performance of the heat exchanger and increase the energy consumption of the air conditioner. At the same time, the heat exchange The dust and dirt of the air conditioner can also breed a large number of bacteria, which will adversely affect the health of users. Therefore, the heat exchanger of the air conditioner needs to be cleaned regularly. [0003] Most of the existing self-cleaning methods for air conditioners use the method of first frosting and then defrosting the heat exchanger to clean the dirt. B...
