Therefore, in the process that the air deflector moves to the closed state, the first driving box is switched to the second state from the first state, so that the first driving device is in driving connection with the second gear, and the second gear is meshed with the second rack so as to drive the air deflector to deflect through the second rack and the first rack. In the process, the deflection angle of the first driving box for driving the air deflector to deflect is larger than the deflection angle of the second driving box for driving the air deflector to deflect, so that the second end of the air deflector is tensioned to act, the air deflector is fully closed on the panel, the problem that the appearance attractiveness of the air conditioner is affected due to the fact that a gap exists between the closed air deflector and the panel in the prior art is solved, the sealing performance and the reliability of the closed air deflector are improved, and the appearance attractiveness of the air conditioner is improved.
