Document Type and Number:
WIPO Patent Application WO/2022/089298
Kind Code:
A1
Abstract:
A tangential fan assembly, an air conditioner and a method for adjusting the air volume of the air conditioner. The tangential fan assembly comprises a tangential fan (700), a rotating motor (500), a power supply shaft (400), an electrode mounting base (100), and a first electrode (200) and a second electrode (300) which are embedded in the electrode mounting base at an interval; the tangential fan comprises supporting discs (710) arranged at intervals, wherein a plurality of moving fan blades (720) are mounted on the supporting discs at intervals in a circumferential direction in a swingable mode, and the plurality of moving fan blades are all connected to an output shaft (510) of the rotating motor; and an inner electrode shaft (421) of the power supply shaft is rotatably electrically abutted against the first electrode, and an outer electrode shaft sleeve (422) is rotatably electrically inserted into a columnar through hole (321) of the second electrode, the inner electrode shaft and the outer electrode shaft sleeve being both electrically connected to the rotating motor. The tangential fan assembly improves the existing fixed fan blade structure, can adjust an air outlet angle of fan blades in real time according to the requirements for air volume, prevents noise caused by a high rotation speed, and also solves the problem that the rotating motor cannot be powered.
