Abstract

The invention discloses a centrifugal wind wheel and an air-conditioner. The centrifugal wind wheel comprises a hub and wheel spokes connected with the hub. The wheel spokes comprise multiple spokes arranged at intervals. Each spoke is provided with a noise reduction hole in a penetrating manner. According to the technical scheme, the noise reduction holes are formed in the spokes of the centrifugal wind wheel, on one hand, the rigidity of the spokes is reduced, and conduction of vibration is weakened; on the other hand, air on the side of a centrifugal wind wheel fan and air on the sides of blades circulate mutually, so that formation of eddy currents is reduced, and the noise of the centrifugal wind wheel is reduced by means of the two aspects together.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a centrifugal wind wheel and an air conditioner equipped with the centrifugal wind wheel. Background technique [0002] The air conditioner is usually provided with a centrifugal wind wheel, and the centrifugal wind wheel will generate noise during operation, thereby affecting user experience. Contents of the invention [0003] The main purpose of the present invention is to provide a centrifugal wind rotor, aiming at reducing the noise generated by the centrifugal wind rotor during operation. [0004] To achieve the above object, the centrifugal wind wheel provided by the present invention includes a hub and spokes connected to the hub, the spokes include a plurality of spokes arranged at intervals, and noise reduction holes are formed through the spokes. [0005] Preferably, each of the spokes is provided with two noise reduction holes. [0006] Preferably, the two...
