Washing machine motor with mute function

Abstract

The invention provides a washing machine motor with the mute function. The washing machine motor comprises a rotating shaft (1), a rotor (2), a stator (3), a bearing (4) and an end cover (5). The washing machine motor is characterized in that the rotor (2) comprises an inner rotor (21) and an outer rotor (22); a plurality of external bulges (23) are arranged on the inner rotor (21); a plurality of inner bulges (24) are arranged on the outer rotor (22); permanent magnets (25) which are uniformly distributed are connected to the outer surface of the outer rotor (22); a PBT (Polybutylece Terephthalate) connecting seat (26) is arranged between every two adjacent permanent magnet bodies (25); an annular rubber vibration absorbing layer (27) is arranged between the inner rotor (21) and the outer rotor (22); a plurality of sound absorption holes (28) are arranged in the rubber vibration absorbing layer (27); a plurality of concave grooves (29) are arranged in the inner surface and the outer surface of the rubber vibration absorbing layer (27). With the adoption of the washing machine motor with the mute function, the rubber vibration absorbing layer can be prevented from falling off, the motor can work normally, and the advantages of good vibration absorbing effect and good mute effect are brought.

Description

[0001] technical field [0002] The invention relates to a washing machine motor, in particular to a washing machine motor with a mute function. Background technique [0003] 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. However, during the operation of the existing washing machine, due to the high-speed rotation of the motor, it is inevitable that the internal rotor and the motor as a whole will vibrate to a certain extent, thereby generating noise. In order to solve the above problems, a layer of rubber damping layer is generally arranged between the inner rotor and the outer rotor to reduce the vibration of the motor rotor. However, the rubber damping layer 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 t...

AI Technical Summary

Problems solved by technology

However, the rubber damping layer 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 of relatively high noise, the rubber shock-absorbing layer is easy to fall off, the shock-absorbing effect is not ideal, and it is easy to affect the operation of the motor.
