Description

Technical Field

[0001] The utility model relates to the technical field of food processing, and more specifically to a variable speed high voltage brushless motor for food processing. Background Art

[0002] Multi-function food processors usually use series motors or induction motors as power sources. However, the speed of series motors is strongly related to the load, resulting in unstable speed and difficulty in maintaining a constant speed when the load changes.

[0003] In order to solve the problems faced by traditional multi-function food processors when using cross-excitation motors or induction motors, the use of brushless motors can automatically adjust the speed according to different load requirements. It also has the advantages of energy saving, noise reduction, improved precision, enhanced stability and reduced maintenance costs.

[0004] However, existing brushless motors generate heat internally when working, and rely entirely on the brushless motor itself for heat dissipation, resulting in a slow cooling rate, which in turn reduces the operating performance of the brushless motor. Some brushless motors use a single fan for heat dissipation, but the heat dissipation effect is not significant. Brushless motors are often damaged due to excessive temperature, which shortens the service life of the brushless motor and increases maintenance costs. Utility Model Content

[0012] Technical effects and advantages of the utility model:

[0013] 1. The utility model is provided with a heat dissipation fan, a heat dissipation aluminum plate and a heat dissipation aluminum sheet. The heat dissipation aluminum plate and the heat dissipation aluminum sheet have good thermal conductivity and a large contact area with the air. They can quickly transfer the heat generated by the brushless motor body to the air, thereby dissipating the heat of the brushless motor body.

When the temperature control switch detects that the temperature inside the stirring drive base exceeds the threshold for starting the micro-circulation water pump, and the heat dissipation fan, the heat dissipation aluminum plate and the heat dissipation aluminum sheet cannot meet the heat dissipation demand, the micro-circulation water pump is started to pump the water inside the water storage frame through the water inlet main pipe and the water inlet branch pipe into the inner side of the water hole of the left heat dissipation aluminum sheet, and then enters the inner side of the water hole of the right heat dissipation aluminum sheet through the connecting pipe. Water has a large specific heat capacity and can quickly absorb the heat of the heat dissipation aluminum sheet. The water that absorbs the heat flows back to the inner side of the water storage frame through the water outlet branch pipe and the water outlet main pipe in turn, thereby realizing water-cooled heat dissipation.
