The lengths of the air deflector 1, the auxiliary air deflector 23 and the cleaning member 21 are basically consistent, and the auxiliary air deflector 23 is used as a carrier of the cleaning member 21 to control and install the cleaning member 21 more conveniently due to the smaller width of the cleaning member 21. When the second motor 22 drives the auxiliary air deflector 23 to rotate, the auxiliary air deflector 23 drives the cleaning member 21 to rotate to adjust the working angle. Meanwhile, the auxiliary air deflector 23 is matched with the air deflector 1 to play a role in stabilizing air outlet, so that air outlet of the air conditioner does not blow a human body strongly.

Wherein, a fourth motor 7 is arranged on one side of the air deflector 1, and the fourth motor 7 is used for controlling the switching of the air deflector 1 between a closed position and an open position. Fig. 12 is a schematic diagram of an operation flow of an indoor unit of an air conditioner according to an embodiment of the present utility model when the indoor unit is performing air supply and self-cleaning. When the air conditioner starts to operate, the closed air conditioner indoor unit is converted from the state of fig. 6 to the state of fig. 7, the filter screen cover plate 9 and the panel 10 slide open to expose the air inlet and the air outlet, the fourth motor 7 operates to drive the air deflector 1 to open the angle, namely the air deflector 1 is switched to the open position, and then the third motor 41 operates to push out the driving assembly 3.
