Abstract
The utility model provides a centrifugal wind wheel component which comprises a centrifugal wind wheel (1), a motor (2) and a motor supporting plate (3), wherein the motor (2) is fixed on the motor supporting plate (3); the centrifugal wind wheel (1) is fixedly mounted on a rotating shaft of the motor (2); and the centrifugal wind wheel component is characterized in that an annular support (12) is arranged at the blade tips (11) on the inner rings of blades of the centrifugal wind wheel (1). The annular support structure is arranged at the blade tips on the inner rings of blades of the centrifugal wind wheel, so that the rigidity of the blades of the centrifugal wind wheel is enhanced, the vortex flow of the blade tips on the inner rings of blades is reduced, the abnormal sounds radiated by the vibration of the blades and the vortex flow of the blade tips are avoided when the centrifugal wind wheel rotates, and the noises of the vibration of the blades and the pneumatic power of the wind wheel are lowered at the same time.
Description
Technical field
The utility model relates to a kind of centrifugal wind wheel assembly, particularly a kind of centrifugal wind wheel assembly that is used for cabinet air conditioner.
Background technique
The existing employed centrifugal wind wheel assembly of cabinet air conditioner comprises centrifugal wind wheel, motor and motor support plate, centrifugal wind wheel is fixed on the motor shaft, motor is by rubber pad and being bolted on the motor support plate, motor support plate is connected with the indoor apparatus of air conditioner backboard by spot welding, when the centrifugal wind wheel high speed rotating, air-flow along impeller shaft to entering blade, collision blade interior edge face, produce bigger aerodynamic noise, and produce ear-piercing different sound simultaneously, in addition, because centrifugal wind wheel, motor, the sound coupling of shaking between motor support plate and the backboard, the wind wheel of air conditioner and backboard can produce very ear-piercing different sound under some frequency, greatly influenced the travelling comfort of air-conditioning.
The model utility content
The purpose of this utility model is to consider the problems referred to above and a kind of different sound of being produced in the centrifugal wind wheel rotary course of suppressing is provided, and reduces noise, thereby improves the centrifugal wind wheel assembly of air conditioner travelling comfort.
The technical solution of the utility model is: a kind of centrifugal wind wheel assembly, comprise centrifugal wind wheel, motor and motor support plate, wherein motor is fixed on the motor support plate, centrifugal wind wheel is packed in the rotating shaft of motor, it is characterized in that the blade inner ring blade tip place of described centrifugal wind wheel is provided with annular brace.
The periphery of above-mentioned motor support plate is provided with some through holes, and indoor apparatus of air conditioner backboard relevant position is provided with some mounting holes, and link passes the set through hole of motor support plate motor support plate is packed on the backboard.
The utility model is owing to adopt the blade inner ring blade tip place of centrifugal wind wheel to be provided with the structure of annular brace, increased the centrifugal wind wheel blade stiffness, reduce blade inner ring blade tip eddy current, the different sound that blade vibration and blade tip eddy current give off when having avoided the centrifugal wind wheel rotation has reduced blade vibration and wind wheel aerodynamic noise simultaneously.
The periphery that the utility model further is improved to motor support plate is packed on the backboard by screw, motor support plate forms comparatively flexible cantilevered support structure, eliminate the partial vibration energy that passes to backboard in the centrifugal wind wheel rotary course, thereby effectively solved the different mail topic that backboard resonance causes, reduced backboard vibration and sound radiation simultaneously.
