Description

Damping structure of low-noise forward-leaning centrifugal fan for air conditioner

Technical Field

The utility model relates to a field of fan, concretely relates to idle call low noise incline centrifugal fan's shock-absorbing structure forward.

Background

Centrifugal fans are widely used for cooling and ventilation in air conditioning equipment and household electrical appliances. Along with the increasing of people's material standard of living, also more and more high to air conditioning equipment's requirement, in order to satisfy people to the requirement of low noise in the air conditioner operation, need improve current air conditioning equipment's centrifugal fan shock-absorbing structure.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide the shock-absorbing structure of the centrifugal fan that leans forward of idle call low noise, have simple structure, simple to operate, during operation reliable and stable advantage.

The purpose of the utility model is accomplished through following technical scheme: the damping structure of the low-noise forward-leaning centrifugal fan for the air conditioner comprises a wind wheel, a volute and a motor, wherein the wind wheel connected and driven by the motor is embedded in the volute, an outlet of a blade of the wind wheel faces to an air outlet of the volute, and air inlets on two sides of the wind wheel respectively face to two side walls of the volute; the motor is characterized in that a triangular plastic shaft sleeve is fixedly mounted on output shafts at two ends of the motor through screws, triangular damping rubber is sleeved outside each triangular plastic shaft sleeve, an aluminum die-casting triangular support is sleeved outside the triangular damping rubber, three support arms extend out of the aluminum die-casting triangular support, and the end part of each support arm is fixed on the side wall of the volute, so that the motor and the volute are fixedly mounted.

As a further technical scheme, the wind wheel is connected to a flange of the motor through screws.

As a further technical scheme, a threaded hole is formed in the position, corresponding to the support arm, of the side wall of the volute, a clamping groove is formed in the end portion of the support arm and used for embedding and installing cylindrical damping rubber, and a through hole is formed in the cylindrical damping rubber and used for enabling a screw to penetrate through to enable the aluminum die-casting triangular support to be fixedly connected with the volute through threads.

The utility model has the advantages that: utilize triangle plastic axle sleeve, triangle damping rubber and cylindrical damping rubber 7, form three-layer shock-absorbing structure between the subassembly of motor and wind wheel and metal spiral case, effectively reduce resonance, realize equipment operation low noise.
