Abstract

The invention discloses a centrifugal fan blade assembly and an air conditioner with the centrifugal fan blade assembly. The centrifugal fan blade assembly comprises a chassis and multiple blades. Themultiple blades are fixed to the chassis, and the multiple blades are distributed at intervals in the circumferential direction of the chassis. Saw-toothed structures are arranged on the end faces ofthe ends, away from the chassis, of at least part of the multiple blades and comprises multiple tooth grooves distributed at intervals in the width directions of the blades. According to the centrifugal fan blade assembly, the saw-toothed structures are arranged at the ends, away from the chassis, of the blades, rotational flow between the blades and flow collecting parts is guided by the tooth grooves, the flow field on an air inlet of the air conditioner is improved, the effective air inlet area is increased, the air amount is increased, and meanwhile noise lowered.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a centrifugal fan assembly and an air conditioner. Background technique [0002] The air inlet of the centrifugal wind wheel is usually provided with a collector, and there is a gap between the collector and the centrifugal wind wheel. When the air flows into the centrifugal fan from the collector, due to the existence of the gap, it is easy to enter the centrifugal fan There is a large swirl at the tuyere, which reduces the effective air intake area, reduces the air volume, and generates more noise. Contents of the invention [0003] In order to solve the above technical problems, the main purpose of the present invention is to provide a centrifugal fan blade assembly and an air conditioner, aiming at solving the existing technical problem of centrifugal fan blades with small air volume and high noise. [0004] In order to achieve the above object, the centrifugal bl...
