Optionally, the third unit 43 controls the fan 5 to rotate by a first preset angle each time, the first preset angle is related to the number of fan blade areas, the fan blades are equally divided into N areas, N is greater than or equal to 2, and N is a positive integer, the fan blades of the fan are divided into areas, after the cleaning device 2 rotates and expands each time, the cleaning device 2 swings up and down to clean one area from top to bottom, after the cleaning of the area is completed, the cleaning device 2 rotates to retract and reset, after the fan rotates by the first preset angle, the cleaning device 2 rotates and expands again to clean the fan blade area, optionally, the first preset angle α is at least 180 °.
When the cleaning devices 2 are arranged on the plurality of guide devices and are uniformly distributed on different positions of the surface of the air channel, the value of the first rotating angle is related to the distribution number of the guide devices. The more the guiding means, the larger the value of the rotation angle, and the more the area that can be cleaned in a certain time.
Optionally, after the third unit 43 controls the fan 5 to rotate for a first preset number of times, the self-cleaning mode is ended. The first preset times of rotation is set, and all areas of the fan blades are cleaned more comprehensively and thoroughly. The first preset times are related to the number of fan blade areas, the fan blades are divided into N areas, N is larger than or equal to 2, and N is a positive integer. The fan blade is divided into areas, after the cleaning device 2 rotates and expands every time, the cleaning device swings up and down to clean one area from top to bottom, after the cleaning of the area is completed, the cleaning device 2 rotates, is folded and reset, after the fan rotates for a first preset angle, the cleaning device 2 rotates and expands again to clean the fan blade area, and after the fan rotates for a first preset time, the cleaning is finished. The fan blade area can be cleaned repeatedly by setting the first rotating frequency, so that the fan blade area is more comprehensive and thorough.
Optionally, a fourth unit 44 is further included for controlling the spraying device 6 to spray the fan blades while the cleaning device 2 is rotated and unfolded to clean the fan blades. After the self-cleaning mode is finished, the water pan is washed through the condensed water pipeline.
Optionally, after the first preset time is over, the spraying device stops operating. Optionally, when the cleaning device 2 rotates to the initial position, the spraying device stops operating. Optionally, the spraying device sprays the fan blade integrally; or the fan blades can be respectively sprayed according to regions. Optionally, the water pan is a drawer-type push-pull device arranged at the bottom of the fan blade. In the self-cleaning process, the cleaning device 2 sweeps dust on the fan blades in the corresponding area into the water receiving tray, and spray water of the spraying device also falls into the water receiving tray; after the cleaning is finished, the condensed water pipeline is automatically connected to clean the water pan without manual cleaning. The spraying device is used for spraying, so that stains attached to the fan blades can be effectively removed, and the region of the fan blades is cleaned, so that the fan blades can be comprehensively and thoroughly automatically sprayed
By adopting the fan blade self-cleaning device shown in fig. 3, the guide device is driven to move up and down by controlling the driving device, so that the cleaning device 2 rotates and expands to clean the fan blade. And the fan blade rotates for many times according to the preset angle, thereby realizing comprehensive and thorough automatic cleaning of the fan blade.
Fig. 4 shows an alternative embodiment of an air conditioner.
In the optional embodiment, the air conditioner is provided with the fan blade self-cleaning device, so that the fan blades of the air conditioner can be comprehensively and thoroughly cleaned automatically.
