Abstract

The invention relates to the field of ventilating equipment. An oblique-flow centrifugal impeller for an air conditioner comprises a circular blade base board, a hub, blades and a deflector ring, wherein the number of the blades is seven; the blade axis angles between adjacent blades are different; each blade is twisted from the air intake end to the air exit end; the upper air intake angle and the lower air intake angle are both not smaller than 10 degrees; the upper air exit angle and the lower air exit angle are both between 20-45 degrees; the upper part of each blade is composed of a connecting section and a non-connecting section which are connected into a whole, and the length of the connecting section accounts for 80-89% of the length of the top of the blade; and the air intake area between any adjacent blades is 76-85% of a corresponding air outlet area. The oblique-flow centrifugal impeller for the air conditioner has the advantages of novel structure, large air flow and low noise.

Description

Technical field [0001] The invention relates to the field of ventilation equipment, in particular to a diagonal flow centrifugal impeller used in air conditioners. Background technique [0002] The oblique flow centrifugal impeller is a commonly used product in air conditioners. The oblique flow centrifugal impeller includes a circular blade bottom plate, a hub, a blade and a flow guide ring. The blades are fixed between the circular blade bottom plate and the flow guide ring, and the hub and the circular ring The inner side of the blade bottom plate is connected as a whole, the hub is concentric with the annular blade bottom plate, and a shaft sleeve is arranged at the center of the top of the hub. When in use, the motor shaft passes through the upper shaft hole of the shaft sleeve to drive the impeller to rotate. The performance of the diagonal flow centrifugal impeller is mainly reflected in the air volume and noise control. The air volume and the noise level are mutual. Gener...
