Background

The cleaning machine is common kitchen cleaning equipment, and the labor intensity of kitchen work is greatly reduced due to the appearance of the cleaning machine.

Although the open water pump can pump cleaning water, dynamic and static interference exists between the blades and the volute in the rotating process, so that the noise is extremely high. In addition, the centrifugal pump system can generate more bubbles in the process, the output capacity is reduced due to the reduction of the liquid density, and the lift of water sprayed by the spray arm is reduced, so that the tableware cleaning is not facilitated. Still some cleaning machines adopt traditional piston pump structure to realize the pumping to the washing water, but because traditional pump structure needs to set up the piston part alone, has led to whole pump water system to produce great vibration in the course of working, and current cleaning machine only through the measure that increases the shock pad, hardly fundamentally reduces the emergence of vibration.
