[0054] Specifically, the air conditioner of the present application has two dust removal cleaning modes. When the real-time working state of the air outlet plate is the closed state, i.e. the air conditioner is just started, the air conditioner executes the first dust removal cleaning mode; when the real-time working state of the air outlet plate is the open state, i.e. the air conditioner is continuously running, the air conditioner executes the second dust removal cleaning mode. By obtaining and judging the real-time working state of the air outlet plate, the corresponding dust removal cleaning mode can be executed in different stages of the air conditioner running, which maximizes the avoidance of the dust removal of the filter 20 not being in place or the filter 20 being excessively cleaned.

[0055] In specific implementation, the first dust removal cleaning mode is as follows:

[0056] 1.1, the cleaning member 10 is initially in the second position. When it is judged that the real-time working state of the air outlet plate is the closed state, it is determined whether the real-time time of the air conditioner is in the daytime working period.
