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

Abstract

The invention discloses a self-cleaning method and device of an air conditioner, the air conditioner and electronic equipment. The self-cleaning method comprises the following steps of entering a refrigeration and condensation stage in response to a self-cleaning instruction for the air conditioner; identifying an end condition meeting the refrigeration and condensation stage of the air conditioner, controlling a compressor to operate for a first preset duration in a frequency limited mode, and controlling the rotating speed of an indoor fan to be less than or equal to the set rotating speed in a frequency limited operation process of the compressor; and controlling the air conditioner to enter a heating and defrosting stage. According to the self-cleaning method in the embodiments of theinvention, the frequency limited operation of the compressor can be controlled before the air conditioner is controlled to enter the heating and defrosting stage, so that a problem that the air conditioner is damaged due to too large difference between the high pressure and the low pressure, which is caused by mode switching of the refrigerating and heating modes of the air conditioner, can be avoided, and the waiting time of a user can also be 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...
