Description

Technical Field

[0001] The utility model relates to the technical field of motor end covers, in particular to a washing machine motor end cover provided with a heat dissipation structure. Background Art

[0002] The motor end cover of a washing machine is a cover located at the rear end of the motor. The material of the end cover is usually metal. In a washing machine, the motor end cover can effectively isolate the internal parts of the motor from the external environment, ensuring the normal operation of the motor and extending its service life. At the same time, the end cover also plays the role of fixing and supporting the motor, ensuring the stability and safety of the motor during operation.

[0003] The existing washing machine motor generates heat when working, and most of the existing washing machine motor end covers are sealed. The heat generated by the washing machine motor when working is not easy to discharge. The washing machine motor is prone to malfunction due to high temperature, and the protection effect of the washing machine motor is poor. The service life of the washing machine motor is short. Therefore, we propose a washing machine motor end cover with a heat dissipation structure. Utility Model Content
