Abstract

The invention discloses a detection method and device for filth blockage of a filter screen of an air conditioner and the air conditioner. The method includes the steps that the target rotating speed obtained when a draught fan stably works according to the preset constant air volume at present is obtained after the draught fan of the air conditioner is controlled to run according to the default initial rotating speed; the initial rotating speed of the draught fan of the air conditioner is obtained when the draught fan runs according to the preset constant air volume for the first time; and whether filth blockage happens to the filter screen arranged in an air feeding pipeline of the air conditioner or not is determined according to the current target rotating speed and the initial rotating speed of the draught fan. The detection method and device solve the technical problem that in the prior art, filth blockage happening to the filter screen arranged in the air feeding pipeline of the air conditioner can not be accurately detected.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a method and device for detecting dirty and clogged air conditioner filter screens and an air conditioner. Background technique [0002] After the air conditioner is in use, the filter screen of the air supply duct grows with time, and dust continues to accumulate, causing dirty blockage. When the filter is dirty and clogged, the air quality of the air conditioner will be affected, and the air output volume of the air conditioner will also decrease accordingly. In order to ensure a constant air output volume, it is necessary to increase the output capacity of the air conditioner, resulting in increased energy consumption of the air conditioner. [0003] In the prior art, there are two solutions to whether the filter screen of the air conditioner is dirty and clogged. First, the operating time of the air conditioner is used as the basis for judgment. In this method, reminders are ...
