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

Abstract

The invention discloses a self-cleaning method and device of an air conditioner, the air conditioner and an electronic device. The self-cleaning method comprises the following steps: by responding toa self-cleaning instruction aiming at the air conditioner, acquiring a first target temperature of an evaporator in the air conditioner; detecting the temperature of an indoor coil pipe, and adjustingthe rotating speed of an indoor fan in the air conditioner according to the temperature of the indoor coil pipe; and if the recognition shows that the temperature of the indoor coil pipe is reduced to the first target temperature, controlling the air conditioner to enter a defrosting stage. According to the self-cleaning method provided by the embodiment of the invention, whether a frosting stageof the air conditioner is finished or not can be judged according to the first target temperature of the evaporator in the air conditioner, then that enough frosting amount is generated in an indoorheat exchanger is ensured, so that the indoor heat exchanger can be thoroughly cleaned, meanwhile, the situation that the temperature of the indoor coil pipe is too low, so that the frosting amount generated in the indoor heat exchanger is excessively high, and consequently, energy waste and heat exchanger damage are caused is solved.

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...

AI Technical Summary

Problems solved by technology

For this reason, an object of the present invention is to propose a self-cleaning method of an air conditioner, which can judge whether the frosting stage of the air conditioner is over according to the first target temperature of the evaporator in the air conditioner, and ensure that the indoor heat exchanger generates enough The amount of frosting in the indoor heat exchanger can be thoroughly cleaned, and the temperature of the indoor coil is too low, resulting in excessive frosting in the indoor heat exchanger, resulting in energy waste and damage to the heat exchanger.
