Description

Technical Field

[0001] This application relates to the field of ice crushing module technology, and in particular to ice crushing module motor assembly. Background Technology

[0002] The ice crushing module is the core component of an ice maker or ice crushing equipment, responsible for driving the ice crushing device (such as blades or a spiral propeller) to break ice into the required small particles.

[0003] In the prior art, the drive end of the drive motor drives the blades in the ice crushing module to rotate via belt drive to crush the ice. The synchronous belt drive reduces the speed output of the drive motor to prevent the ice crushing module from being damaged due to excessive speed.

[0004] Regarding the aforementioned technologies, the inventors believe that the ice-crushing module reduces the speed output of the drive motor through synchronous belt transmission. During operation, the instantaneous transmission ratio of the synchronous belt transmission will change, affecting the speed and torque delivered by the drive motor to the stirring shaft. Utility Model Content

[0005] The purpose of this application is to provide a motor assembly for an ice crushing module to improve the problem that changes in the instantaneous transmission ratio of the synchronous belt drive during operation affect the speed and torque delivered by the drive motor toward the stirring shaft.

[0006] The ice-crushing module motor assembly provided in this application adopts the following technical solution:

[0007] The ice-crushing module motor assembly includes an upper end cover and a drive motor disposed on the outside of the upper end cover.

A plurality of reduction gear sets are disposed between the upper end cover and the lower end cover, and the plurality of reduction gear sets mesh with each other for transmission. One set of reduction gear sets is fixedly connected to the drive end of the drive motor. An ice-crushing stirring shaft is disposed on the end of the upper end cover away from the drive motor, which is axially connected to one of the reduction gear sets.

[0008] By adopting the above technical solution, a drive motor installed on the upper end cover drives several reduction gear sets to rotate. Through the meshing of multiple reduction gear sets, transmission is achieved by gradually reducing the speed, matching the torque and speed required for ice crushing. The reduction gear sets drive the ice crushing and stirring shaft to rotate. Compared with synchronous belt transmission, the transmission efficiency is higher, the friction loss is lower, and the instantaneous transmission ratio is constant, reducing the impact on the speed and torque delivered by the drive motor to the ice crushing and stirring shaft. At the same time, the gears in the reduction gear sets are not prone to aging or loosening during high-speed and continuous operation.

[0009] Optionally, several of the reduction gear sets are offset from each other between the upper end cover and the lower end cover.

[0010] By adopting the above technical solution, several reduction gear sets are staggered between the upper and lower end covers, resulting in a simple and compact structure that reduces the space occupied by the reduction gear sets and the overall space occupied by the ice crushing module.

After the card plate at the bottom of the ice crusher is embedded in the groove, it is in close contact with the water-proof gasket to seal it, preventing the water from melting after the ice is crushed from flowing out of the ice crusher and affecting the drive motor.

[0019] Optionally, the upper end cover has a limiting groove on the side facing the drive motor that corresponds to the end of the drive motor, and the outer side of the upper end cover has an annular protrusion corresponding to the drive motor.
