The air deflector is disposed at the air outlet through the rotation of the rotating shaft, and the opening, closing and the direction of the air outlet are adjusted by controlling the rotation of the air deflector.

Due to the limited rotation of the air deflector, its size is smaller than the size of the air outlet to avoid interference with the inner wall of the air outlet. This results in a certain gap between the edge of the air deflector and the inner wall of the air outlet when the air deflector is closed relative to the air outlet, and the gap is generally above 0.8 mm, so that the air deflector is sealed with respect to the air outlet. The effect is low, and it is easy for external dust to enter the interior of the refrigeration device along the gap.
