Further, the flexible resilient sheet 2 may be provided on only one flow guiding surface, as described in the above embodiments. Or, the flexible elastic sheet 2 can be arranged on the two flow guide surfaces simultaneously.

Preferably, when the air conditioner is closed, the surface of the air deflector main body 1 provided with the flexible elastic sheet 2 is positioned at the inner side, so that the overall appearance of the indoor unit 3 is more attractive.
When the air conditioner works, the air deflector rotates to be in a horizontal state, the air outlet is opened, the air guiding effect is achieved, when a user opens the middle-low windshield, the air speed is low at the moment, flow separation is not prone to occurring, the flexible elastic pieces 2 keep a natural state, so that the air deflector main body 1 keeps the best molded line, for example, when the air deflector main body 1 is an airfoil plate, air flow is blown out along the molded line of the surface of the air deflector, the flow dissipation is lower than that of a common air deflector, and excessive air volume loss is avoided while the good air guiding effect is achieved.
When a user opens the powerful windshield, the wind speed is high, the wind pressure is high, the flexible elastic sheet 2 can bounce passively due to pressure difference, the flexible elastic sheet 2 swings up and down under the continuous interaction between the flexible elastic sheet 2 and the airflow, the flexible elastic sheet 2 changes the flowing direction and the flowing form of the airflow when constantly acting on the airflow, and the airflow is closer to the array natural wind, so that the soft wind effect is achieved.
