Through setting up the shaft hole on the extension line of spout 8, can make the more balanced distribution of the thrust of hydraulic stem 9 to first driven lever 6 and second driven lever 7, make first driven lever 6 and second driven lever 7 more smooth and easy motion.

Alternatively, the hydraulic rod 9 comprises a push rod and a piston. Wherein, the piston is used for cutting off the liquid in the upper cavity and the lower cavity.

Wherein, the driving gear can drive the driven gear to rotate, thereby driving the liquid in the hydraulic chamber 10 to flow in the forward or reverse direction. When the power drives the driving gear to rotate in the positive direction, liquid in the hydraulic cavity 10 flows into the lower cavity from the upper cavity through the connecting piece, and the hydraulic rod 9 moves upwards in a straight line, so that the first air deflector 1 and the second air deflector 2 can be driven to rotate until the air outlet is closed; when the power drives the driving gear to rotate reversely, liquid in the hydraulic cavity 10 flows into the upper cavity from the lower cavity through the connecting piece, and the hydraulic rod 9 moves downwards linearly, so that the first air deflector 1 and the second air deflector 2 can be driven to rotate to open the air outlet.

The preset angle is an angle at which the first air deflector 1 starts to rotate from an initial state. The predetermined angle range is any angle between 0 degrees and 30 degrees. The small angle opening between 0 and 30 degrees can form cold air or hot air circulation outside the air-conditioning indoor unit, so that the internal and external temperatures of the air-conditioning indoor unit are consistent as soon as possible, and the condensation probability of condensed water and the possibility of expansion with heat and contraction with cold are reduced.

Specifically, when the air-conditioning indoor unit is in a high-humidity environment, the rotation speeds of the first air deflector 1 and the second air deflector 2 are firstly increased, and the movement displacement of the hydraulic rod 9 is controlled to control the first air deflector 1 and the second air deflector 2 to rotate by a preset angle, so that air flow is intensively blown out from small-angle air ports of an upper air path and a lower air path. The air blown out from the upper air passage flows through the front wall surface and the upper wall surface of the shell 3, and the air blown out from the lower air passage flows through the lower wall surface and the back wall surface of the shell 3, so that an external circulation wind field is formed by airflow on the shell of the indoor unit of the air conditioner, the indoor air conditioner is prevented from staying near the shell of the indoor unit of the air conditioner for a long time, and the condensation problem is avoided.
