Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a liquid-cooled induction motor pump mechanism. Background Art

[0002] At present, most of the existing induction motors use air cooling for heat dissipation, including separate fan cooling and motor built-in fan cooling. However, both methods have the disadvantages of uneven heat dissipation, poor heat dissipation effect, high cost and high energy consumption. Therefore, it is necessary to use external circulating water cooling and internal heat conduction solutions for the heat dissipation of induction motors, and water-cooling the induction motors of products involving water jets, so as to improve the above disadvantages.

[0003] In addition, the coils of the induction motor heat up due to the current during operation, which will affect the motor efficiency to a certain extent. In addition, there is no good heat conduction medium between the coils inside the motor, resulting in energy loss. If the heat cannot be dissipated, it will still affect the motor efficiency and service life, resulting in serious consequences such as energy loss and motor stopping or burning.

[0004] Therefore, heat dissipation of the induction motor is a very important part of the process. Therefore, we need to propose a liquid-cooled induction motor pump mechanism to overcome the above problems. Utility Model Content

If the heat cannot be dissipated, it will still affect the motor efficiency and the service life of the motor, thereby causing energy loss and serious consequences such as the motor stopping working or burning.
