After the air conditioner is placed or used for a long time, the indoor heat exchanger or filter of the air conditioner tends to accumulate a large amount of dust, resulting in a decline in the performance of the air conditioner
[0003] Some air conditioners in the prior art determine whether the air conditioner needs to enter the self-cleaning mode by judging the degree of dirtyness of the indoor heat exchanger (judging the pressure difference between the inlet and outlet of the indoor heat exchanger and the operating current of the indoor fan). However, in some specific environments High-end air conditioners, such as kitchen air conditioners, are used in environments with high oil pollution. In this environment, the surface of the indoor heat exchanger is easily contaminated by oil pollution, and only oil pollution will not cause a significant increase in the wind resistance of the indoor heat exchanger. The thermal capacity and the health of the operating environment have been greatly affected. In this case, only judging the degree of dirtyness of the indoor heat exchanger cannot truly reflect the degree of pollution of the indoor heat exchanger, so timely self-cleaning of the air conditioner cannot be performed , resulting in a decline in the performance of the air conditioner and affecting the health of the user

The invention discloses an air conditioner and a self-cleaning method. The controller of the air conditioner is configured to record the natural duration from the end of the last self-cleaning and the working duration of the air conditioner; The oil pollution degree coefficient corrects the working time, and determines the corrected working time; the comprehensive time is determined according to the natural time and the corrected working time, if the comprehensive time is greater than the first preset time and not greater than the second preset If the time is long, a prompt message that the air conditioner needs to perform self-cleaning is sent to the user, so that self-cleaning can be performed accurately and in a timely manner.
Description
technical field [0001] The present application relates to the field of air conditioner control, and more specifically, to an air conditioner and a self-cleaning method. Background technique [0002] Air conditioners have become more and more popular in people's lives, and consumers have higher and higher requirements for the functions of air conditioners. After the air conditioner is placed or used for a long time, a large amount of dust and dirt tend to accumulate on the indoor heat exchanger or filter screen of the air conditioner, resulting in a decline in the performance of the air conditioner. [0003] Some air conditioners in the prior art determine whether the air conditioner needs to enter the self-cleaning mode by judging the degree of dirtyness of the indoor heat exchanger (judging the pressure difference between the inlet and outlet of the indoor heat exchanger and the operating current of the indoor fan). However, in some specific environments High-end air condi...
