Abstract

The invention provides a method for judging a blockage degree of a dust filter screen of an air conditioner. The method for judging the blockage degree of the dust filter screen of the air conditionercomprises the following steps that the humidity of an environment in which an indoor unit of the air conditioner is located is acquired to obtain an indoor humidity value; current of a motor of an indoor fan of the indoor unit is acquired to obtain a measured current value; a current judgment threshold corresponding to the indoor humidity value is acquired; and according to the measured current value and the current judgment threshold, the blockage degree of the dust filter net is judged. According to the method for judging the blockage degree of the dust filter screen of the air conditionerand 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...
