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 a self-cleaning instruction for the air conditioner is responded; the accumulated operation duration and the indoor relative humidity of the air conditioner after the last self-cleaning is finished are obtained, and the target operation duration of the air conditioner in a refrigeration and frosting stage is obtained according to the accumulated operation duration and the indoor relative humidity; the air conditioner iscontrolled to run for the target running duration in the refrigeration and frosting stage; and the air conditioner is controlled to enter a defrosting stage. According to the self-cleaning method inthe embodiment, the target operation duration of the air conditioner in the refrigeration and frosting stage can be obtained according to the accumulated operation duration and the indoor relative humidity, so that the obtained target operation duration is closer to the actual frosting requirement; and the air conditioner is controlled to run for the target operation duration in the refrigerationand frosting stage, and therefore, enough frosting amount is ensured to be generated in an indoor heat exchanger, and the indoor heat exchanger is thoroughly cleaned.

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.

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 self-cleaning methods first control the air conditioner to operate in the cooling mode, so that condensed water is generated on the outer surface of the indoor heat exchanger to clean the dirt. This method has the advantages of easy implementation and low cost, and has been widely used. However, this method At the same time, there are problems such as incomplete cleaning and energy waste.
