Specifically, the first position is set as the reset position of the motor 123 , and the motor 123 stops moving after a predetermined number of steps along the first direction, so that the motor 123 drives the wind deflector 121 to move to the second position. When it is necessary to switch the air path, the motor 123 is controlled to travel a predetermined number of steps in a second direction opposite to the first direction and then stop moving, so that the motor 123 drives the wind deflector 121 to move to the first position.

Of course, it can be understood that, in the embodiment where the wind deflector 121 has a first position, a second position, a third position, and a fourth position, the movement of the wind deflector 121 can also be controlled in a manner similar to the above. It is also possible to switch between various positions by controlling the unidirectional rotation of the motor 123. For example, when the wind deflector 121 is in the first position, it can be switched to the fourth position by turning 90° clockwise, it can be switched to the third position by turning 90° clockwise again, and it can be switched to the second position by turning 90° clockwise again.
