Embodiment Construction

[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The main solution of the embodiment of the present invention is to: obtain the wind noise value of the air outlet of the air conditioner collected by the sound collection device; obtain a preset wind noise threshold; when the wind noise value is less than the wind noise threshold , it is determined that the air conditioner filter is dusty.

[0038] Due to the existing technology, the air conditioner often judges the amount of dust accumulated on the filter screen of the air conditioner by the length of use, and because the use area and environment of the air conditioner are not the same, it is difficult to judge the accumulated amount of dust on the filter screen by the length of use. big error.

[0039] The present invention provides a solution. Firstly, according to the wind noise value of the air outlet of ...

Abstract

The invention discloses a dust accumulation detection method for a filter screen of an air conditioner. The air conditioner comprises a sound acquisition device used for detecting the air noise of anair outlet of the filter screen. The dust accumulation detection method for the filter screen of the air conditioner comprises the following steps that the air noise value of the air outlet of the airconditioner collected by the sound acquisition device is acquired; a preset wind noise threshold value is acquired; and when the wind noise value is smaller than the wind noise threshold value, the dust accumulation of the filter screen of the air conditioner is judged. The invention further discloses the air conditioner and a storage medium. According to the dust accumulation device, the air noise value of the air outlet of the air conditioner is collected through the sound acquisition device, and then the collected wind noise value is compared with a preset wind noise threshold value, and when the collected wind noise value is smaller than the wind noise threshold value, the air outlet of the surface filtering net is not smooth, and the amount of accumulated dust on the filtering net isjudged, so that the phenomenon that because the use duration of the air conditioner is long, whether dust accumulation of the filter screen is caused or not is avoided, and the accuracy of judging the dust accumulation amount of the filter screen is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for detecting dust accumulated in a filter screen of an air conditioner, an air conditioner and a storage medium. Background technique [0002] In people's life, the air conditioner is already an indispensable household appliance. After the air conditioner works for a long time, a certain amount of dust will accumulate on the filter and heat exchanger. When the dust accumulates, it will affect the performance of the air conditioner and cause the air conditioner to fail Power consumption increases and bacteria can grow at the same time. In the prior art, judging whether there is too much dust accumulated on the filter screen of the air conditioner and the heat exchanger is often judged by the cumulative use time of the air conditioner. There will be a large error in determining whether the dust has accumulated too much based on the cumulative use time of the pro...
