[0066] Specifically, since the dust accumulation of the filter element 20 will be more serious after it has not been cleaned for a long time, when the filter element 20 has not been cleaned within the past 48 hours, the cleaning element 10 performs a secondary cleaning on the filter element 20, and the liquid spraying element 30 flushes the cleaning element 10 at a relatively large liquid spraying speed; when the filter element 20 has not been cleaned within the past 24 hours, the cleaning element 10 performs a primary cleaning on the filter element 20, and the liquid spraying element 30 flushes the cleaning element 10 at a relatively small liquid spraying speed; when the filter element 20 has not been cleaned within the past 12 hours, the cleaning element 10 performs a secondary cleaning on the filter element 20, and the liquid spraying element 30 flushes the cleaning element 10 at a relatively small liquid spraying speed. During cleaning, the cleaning component 10 cleans the filter element 20 once; if the filter element 20 has been cleaned within the past 12 hours, the spray component 30 does not work, so that the air conditioner can accurately control the cleaning times of the cleaning component 10 and the spraying speed and amount of the spray component 30 according to the dust accumulation degree of the filter element 20, effectively ensuring that the filter element 20 is fully cleaned while avoiding the waste of excessive cleaning of the filter element 20 and the spray component 30 by the cleaning component 10, and also avoiding frequent replacement of the dust removal box 22, thereby reducing the labor intensity of the user.

[0071] In specific implementation, the second dust removal cleaning mode is as follows:

[0072] 1.1. The cleaning member 10 is initially in the second position. When it is determined that the real-time working state of the air outlet plate is the open state, whether the real-time moment of the air conditioner is in the daytime working period is obtained. When the real-time moment is in the daytime working period, the continuous opening time of the air outlet plate is obtained; when the real-time moment is not in the daytime working period, whether the real-time moment of the air conditioner is in the daytime working period is obtained again after m time; (optionally, n is equal to 12 hours and m is equal to 1 hour);

[0073] 1.2. When it is determined that the continuous on time is greater than or equal to 4n, the air conditioner is immediately shut down, the air outlet plate is switched to the off state, and restarted after 30s, and the real-time working state of the air outlet plate is re-determined to be the on state, so that the air conditioner is switched to the first dust removal cleaning mode;

[0076] Specifically, the longer the air outlet plate is continuously opened, the more serious the dust accumulation of the filter element 20 will be. Therefore, when the air outlet plate is continuously opened for greater than or equal to 48 hours, the air conditioner is directly switched to the first dust removal cleaning mode; when the air outlet plate is continuously opened for greater than or equal to 24 hours and less than 48 hours, the cleaning element 10 is controlled to clean the filter element 20; when the continuous opening time is less than 24 hours, the cleaning element 10 and the spray element 30 do not work, so that the air conditioner can accurately control the cleaning times of the cleaning element 10 and the spray speed and spray amount of the spray element 30 according to the dust accumulation degree of the filter element 20, effectively ensuring that the filter element 20 is fully cleaned, while avoiding the waste of excessive cleaning of the filter element 20 and the spray element 30 by the cleaning element 10, and also avoiding frequent replacement of the dust removal box 22, thereby reducing the labor intensity of the user.
