[0002] With the improvement of people's requirements for air quality, air conditioners with filtering function appear continuously on the market. As the air conditioner's filter screen increases with the increase of the air conditioner's operating time, more and more dust will accumulate, which will directly make the air conditioner The air volume decreases, which in turn affects the cooling and heating effects, and even causes air conditioner protection in severe cases.
Traditional air conditioners automatically control the working gear of the indoor fan according to the temperature difference between the target temperature and the indoor environment, without considering the attenuation of the air volume caused by the dirty filter, which will affect the cooling and heating effect of the air conditioner, and sometimes even cause the compressor to fail. shutdown

Embodiment Construction
[0038] The present invention will be described in detail below. In the following paragraphs, different aspects of the embodiments are defined in more detail. Aspects so defined may be combined with any other aspect or aspects unless specifically stated otherwise. In particular, any feature considered to be preferred or advantageous may be combined with one or more other features which are considered to be preferred or advantageous.
[0039] The present invention proposes an air conditioner fan control method, in an exemplary embodiment, as figure 1 As shown in the schematic flow chart, the control method includes:
[0040] Step 101, obtaining the current wind gear of the fan in the air conditioner;
[0041] Step 102, obtaining parameters representing the clogging degree of filter components in the air conditioner;
[0042] Step 103, judging whether the parameter representing the clogging degree of the filter component exceeds the allowable threshold under the current winds...

The present invention relates to an air conditioner fan control method, system and air conditioner, wherein, the control method includes acquiring the current wind gear of the fan in the air conditioner; acquiring a parameter representing the clogging degree of the filter component in the air conditioner; and judging the clogging degree of the filter component Whether the parameter exceeds the allowable threshold under the current wind gear, if yes and the current wind gear is not the highest wind gear, increase the current wind gear by one gear. This control method can increase the air volume by increasing the windshield when the filter parts of the air conditioner are seriously blocked, so as to prevent the air conditioner from entering the anti-freezing, anti-high temperature or compressor protection state, thereby ensuring the cooling and heating effect of the air conditioner. Improve the comfort of use; but also ensure the reliability of the compressor, so as to improve the service life of the whole machine.
