As can be seen from the above description, the blowing mode of the air conditioner can be adjusted according to the blowing mode of the air conditioner by the blowing device 13, and the driving mechanism can control the operation mode of the blowing device 13.
The invention can realize the switching between the soft air supply mode and the common air supply mode of the air conditioner. Under the gentle wind mode, through single motor drive curve pole, drive a plurality of connecting rods, realize a plurality of connecting rods and flexible window screening formula air guide component wave periodic rhythm, the air current flow direction of guide is different, can break up the laminar flow air current originally of air conditioner effectively, realizes the effect similar to natural wind gust habit, avoids cold wind direct-blowing. Under the ordinary air supply mode, the connecting rod becomes a plane, realizes air conditioner laminar flow air-out. The flexible air guide curtain (such as a window screen type air guide structure) periodically swings up and down, so that the air outlet flow of the air conditioner is diffused in a larger angle, the blowing sense is reduced, and the discomfort caused by direct blowing of cold air due to the structural limitation of the air guide plate is realized.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
