Method for judging blockage degree of dust filter screen of air conditioner and air conditioner

Abstract

The invention provides a method for judging the blockage degree of a dust filter screen of an air conditioner. The method comprises the following steps of acquiring an operation mode of the air conditioner; acquiring an initial current value, of a motor of an indoor fan of the air conditioner corresponding to the operation mode; acquiring a plurality of judgment current values of the motor in theoperation mode; and judging the blockage degree of the dust filter screen according to a change trend of the plurality of judgment current values and the size of the initial current value and the judgment current values. According to the air conditioner and the method for judging the blockage degree of the dust filter screen of the air conditioner, the judgment accuracy of the blockage degree of the dust filter screen is improved, the misjudgment is reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method for judging the clogging degree of a dust filter net of an air conditioner and an air conditioner. Background technique [0002] The air inlet of the indoor unit of the existing air conditioner is provided with a dust filter, which is used to filter the air entering the indoor unit and prevent foreign matter such as dust from entering the indoor unit. After a long time of use, dust and other sundries tend to adhere to the dust filter, which will block the mesh of the dust filter. If it cannot be cleaned in time, it will not only reduce the air volume entering the indoor heat exchanger, affect the cooling and heating effects of the air conditioner, but also increase the energy consumption of the air conditioner and shorten the service life of the air conditioner. Most of the existing air conditioners are cleaned by users roughly estimating the use time of the ai...

AI Technical Summary

Problems solved by technology

After a long time of use, dust and other sundries tend to adhere to the dust filter, which will block the mesh of the dust filter

If it is not cleaned in time, it will not only reduce the air volume entering the indoor heat exchanger, affect the cooling and heating effect of the air conditioner, but also increase the energy consumption of the air conditioner and shorten the service life of the air conditioner

Most of the existing air conditioners use the user to roughly estimate the use time of the air conditioner to clean the dust filter, which brings unnecessary additional burden to the user, and it is very likely that the dust filter will be clogged and cannot be dealt with

Although some air conditioners have a reminder function, they only rely on the use time of the air conditioner to remind the clogging, and cannot accurately judge the clogging degree of the dust filter.
