Background
With the increasing level of living of people, dish washers are increasingly entering home as household electrical appliances for kitchen use. The existing dish-washing machines on the market are generally divided into three types of a desk type dish-washing machine, a cabinet type dish-washing machine and a trough type dish-washing machine, wherein the desk type dish-washing machine is of an integral independent structure and is generally placed on a desk for use; the cabinet type dish washer is also an independent structure, but needs to be embedded into a kitchen cabinet for use; the tub dishwasher is combined with a tub and is generally installed in a kitchen cabinet.
The dish washing machine of the above-mentioned various forms generally has a washing function by lifting water by a water pump and spraying the water toward dishes in a washing space.

However, in such a structure, the instantaneous cavitation phenomenon generated between the ultrasonic wave and the high-pressure air bubbles needs to be maintained in water, and when the water flow is lifted by the water pump and is circularly sprayed out, the high-pressure air bubbles are difficult to reach the surfaces of the dishes, and then break, so that the structure is not suitable for the structure of the water flow spraying type dish washing machine. In addition, the structure is only suitable for large-scale dish washers, and is difficult to be suitable for household dish washers.
