Abstract

The invention provides a volute structure, a centrifugal fan and a wall-mounted air conditioner, and the volute structure comprises a volute body arranged in a shell of the wall-mounted air conditioner; the gear ring is meshed with the gear; the gear ring is installed on one axial end face of the volute body, and the gear is installed on a shell of the wall-mounted air conditioner. The gear can drive the gear ring to rotate and drive the volute body to rotate. According to the volute structure, the gear ring is matched with the gear, rotation of the volute body is achieved, compared with an existing rotatable volute, the volute structure has the advantages of being simple in transmission structure, high in transmission efficiency and high in reliability, compared with an immovable volute, wide-angle air supply, partitioned air supply and directional air supply can be achieved through rotation of the volute, and the volute structure is convenient to use. Air supply adjustment is achieved by adjusting the rotating angle of the air duct, and the air supply comfort is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air duct structure, a centrifugal fan and a wall-mounted air conditioner. Background technique [0002] Existing air conditioners with a rotatable volute structure, the volute is rotatably arranged on the outer periphery of the impeller, in order to realize the adjustment of the wind outlet angle of the fan, a gear-rack-pinion two-stage transmission method is adopted, and the transmission The structure is complex, the mechanism is cumbersome, the transmission efficiency is low and the reliability is poor. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is that the transmission structure of the rotatable volute structure is complicated, the transmission efficiency is low and the reliability is poor, so as to provide a volute structure, a centrifugal fan and a wall-mounted air conditioner. [0004]...
