[0018] The method of using the utility model is as follows: firstly, the tableware to be washed is placed on the assembly line conveyor belt 5, which is driven by the driving motor to move in the tableware washing box 1. When it moves to the upper spray pipeline 10 and the lower spray pipeline 11, the water receiving pump 6 is started. The water receiving pump 6 sends the water in the return water tank 2 to the upper spray pipeline 10 and the lower spray pipeline 11, respectively through the upper nozzle 13 and the lower nozzle 14 to produce cavitation effect. Since the upper nozzle 13 and the lower nozzle 14 are inclined cavitation jet nozzles, the tableware can be cleaned by spraying water with cavitation bubbles and utilizing the energy generated by the instantaneous collapse of the cavitation bubbles.

The water flowing back to the return water tank 2 is filtered by the filter 15 and is divided into water and garbage. The water flows from the filter 15 into the water storage area 1 below 7 for storage, the garbage is filtered by the filter 15 and discharged and collected along the oblique filter 15 and through the garbage outlet 18 and the garbage guide plate 31. The water flowing into the water storage area 17 floats on the water due to the small density of the oil pollution, and then passes through the filter at the water inlet of the water receiving pump 6 to remove the oil pollution and fine garbage. The treated water enters the water receiving pump and is pumped into the upper spray pipeline 10 and the lower spray pipeline 11 through the water receiving pump 6 to the assembly line conveyor belt 5, the next batch of tableware on the tableware is washed again and recycled. In addition, when it is recycled, the water in the return water tank 2 is heated to hot water by the electric heater 29. Hot water can provide a better cleaning effect during washing. When the upper spray pipeline 10 and the lower spray pipeline 11 need to be replaced to meet the flushing requirements, the mounting side plate 12 is removed, so the upper spray pipeline 10 and the lower spray pipeline 11 are also removed, so that the upper spray pipeline 10 and the lower spray pipeline 11 can be replaced.
