Problems solved by technology

However, vibration is not the only source of noise during fan operation. The structural combination between the fan casing and the fan wheel is not good, resulting in excessive wind pressure around the fan wheel, which will also cause the fan to generate noise during operation.

Abstract

The present invention relates to a fan housing and fan wheel combined structure and a fan housing thereof. The fan housing and fan wheel combined structure comprises a first housing, a fan wheel and asecond housing; the first housing has a shaft tube part; the fan wheel is pivoted on the shaft tube part of the first housing; the fan wheel comprises a plurality of blades arranged at intervals in an annular shape; the second housing is coupled to the first housing; the second housing has a vent hole and a noise reduction inner ring surface; the vent hole corresponds to the shaft tube portion; and the noise reduction inner ring surface surrounds the vent hole, and the noise reduction inner ring faces the blades. The invention can reduce the wind pressure between the fan wheel and the secondcasing, thereby eliminating the noise generated by the wind pressure and achieving the effect of silence.

Description

technical field [0001] The invention relates to a combined structure of a fan casing and a fan wheel and the fan casing. Background technique [0002] In order to reduce the noise generated during the operation of the fan, the known technology has proposed to reduce the noise by reducing the vibration of the fan during operation. However, vibration is not the only source of noise during fan operation. The structural combination between the fan housing and the fan wheel is not good, resulting in excessive wind pressure around the fan wheel, which will also cause the fan to generate noise during operation. [0003] Therefore, it is necessary to provide an innovative and progressive combined structure of the fan casing and the fan wheel and the fan casing to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a combination structure of a fan casing and a fan wheel and the fan casing which can eliminate the noise gen...
