Self-cleaning method and device of 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 steps that the response to a self-cleaning instruction for the air conditioner is achieved, and the air conditioner is controlled to enter a condensate water forming stage; the situation that the temperature of an indoor coil pipe isreduced to the first preset temperature in the condensate water forming stage is detected, and then the air conditioner is controlled to enter a refrigeration frosting stage; the temperature reductionspeed of the process that the temperature of the indoor coil pipe is reduced to the second preset temperature from the first preset temperature in the refrigeration frosting stage is obtained; the target rotating speed of an indoor fan in the air conditioner in the refrigeration frosting stage is determined according to the temperature reduction speed; and the situation that the temperature of the indoor coil pipe is reduced to the first target temperature of an evaporator in the air conditioner is recognized, and then the air conditioner is controlled to enter a defrosting stage. According to the self-cleaning method, the target rotating speed of the indoor fan in the refrigeration frosting stage can be determined according to the temperature reduction speed, and therefore the problem that due to the fact that the frosting speed is high, the formed frost is not uniform can be solved, the situation that the enough frosting quantity is generated by an indoor heat exchanger is guaranteed, and the cleaning effect of the indoor heat exchanger is enhanced.

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 air conditioner self-cleaning methods first control the air conditioner to operate in the cooling mode, so that the outer surface of the...

Problems solved by technology

[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 will also breed a large number of bacteria, which will adversely affect the health of the user. Therefore, the heat exchanger of the air conditioner needs to be cleaned regularly

[0003] Most of the existing air conditioner self-cleaning methods first control the air conditioner to operate in the cooling mode, so that the outer surface of the indoor heat exchanger is frosted to clean the dirt. This method has the advantages of easy implementation and low cost, and has been widely used , but this method also has problems such as incomplete cleaning and energy waste
