A washing machine motor rotor with mute function

Abstract

The invention discloses a washing machine motor rotor with a mute function. The washing machine motor rotor comprises an inner rotor (1). The outer side of the inner rotor (1) is provided with an outer rotor (2). The outer surface of the inner rotor (1) is provided with a plurality of radially-outward outwards-protruding parts (3). The inner surface of the outer rotor (2) is provided with a plurality of radially-inward inwards-protruding parts (4). The outer surface of the outer rotor (2) is connected with evenly-distributed permanent magnets (5), and PBT connection bases (6) are arranged between every two adjacent permanent magnets (5). An annular rubber shock absorption layer (7) is arranged between the inner rotor (1) and the outer rotor (2), the rubber shock absorption layer is internally provided with a plurality of sound absorption holes (8), and both the inner surface and the outer surface of the rubber shock absorption layer (7) are provided with a plurality of grooves (9). Accordingly, by means of the washing machine motor rotor, the rubber shock absorption layer can be prevented from falling off, normal work of a motor is guaranteed, and the washing machine motor rotor further has the advantages of being good in shock absorption effect and mute effect.

Description

technical field [0001] The invention relates to a washing machine motor rotor, in particular to a washing machine motor rotor with a mute function. Background technique [0002] Along with the development of the washing machine, people require that the noise generated during the operation of the washing machine should be as small as possible. The rotors of washing machine motors currently on the market are generally provided with a layer of rubber damping layer between the inner rotor and the outer rotor to reduce the vibration of the motor rotor, thereby reducing the noise generated during the operation of the washing machine. However, the rubber damping layer in this rotor is easy to fall off from the surface of the inner rotor and the outer rotor, so that there is relative rotation between the inner rotor, the outer rotor and the rubber damping layer, which affects the damping effect and the normal operation of the motor. At the same time, due to the large deformation of...

AI Technical Summary

Problems solved by technology

However, the rubber damping layer in this rotor is easy to fall off from the surface of the inner rotor and the outer rotor, so that there is relative rotation between the inner rotor, the outer rotor and the rubber damping layer, which affects the damping effect and the normal operation of the motor.

At the same time, due to the large deformation of the rubber shock-absorbing layer, the concentricity of the inner rotor and the outer rotor will be relatively large, which will affect the normal operation of the motor.

Therefore, the existing washing machine motor rotor has the problems that the rubber damping layer is easy to fall off, the damping effect is not ideal and the motor work is easily affected.
