Abstract

The invention relates to the field of ventilation devices. The impeller for the air conditioner comprises a circular impeller base plate, a hub, blades and flow guiding rings. The number of the blades is 7, an air inlet angle is not larger than 7 degrees, and an air outlet angle ranges from 25 degrees to 35 degrees. Blade axis angles between adjacent blades are different. The upper portions of the blades are formed by connecting areas connected integrally and non-connecting areas. The length of the connecting areas accounts for 52%-63% of the length of the top portions of the blades, and air inlet area between any adjacent blades is 63%-69% of corresponding air outlet area. The impeller for the air conditioner is novel in structure, large in air amount and low in noise.

Description

technical field [0001] The invention relates to the field of ventilation equipment, in particular to an impeller used for an air conditioner. Background technique [0002] The impeller is a commonly used product in air conditioners. The impeller on the air conditioner includes a circular leaf base, a hub, blades and a guide ring. The blades are fixed between the circular leaf base and the guide ring. The hub and the inside of the circular leaf base Connected as a whole, the hub and the circular blade bottom plate are concentric, and a shaft sleeve is arranged at the center of the top of the hub. When in use, the motor shaft passes through the shaft hole on the shaft sleeve to drive the impeller to rotate. The performance of the impeller used in air conditioners is mainly reflected in the air volume and noise control. The air volume and the noise level are mutually related. Generally, the noise is relatively high when the air volume is large, and the noise is naturally low wh...
