When dirt on the inner and outer barrels of the washing machine is removed, the dirt on the surface of the inner and outer barrels is impacted instantly and continuously under high pressure, and the dirt is damaged and falls off from the surface of the inner and outer barrels; when the clothes are washed, the bubbles generated by cavitation are continuously generated, enlarged and collapsed, the washing water is continuously impacted, the solubility of the detergent is increased, meanwhile, the bubbles enter the inner barrel along with the washing liquid, and the instantaneous pressure generated by collapse of the bubbles acts on the surfaces of the clothes, so that the clothes washing effect is improved.

When the interior of the washing machine is cleaned, a certain amount of cleaning water is added into the outer barrel 1 of the washing machine through the water inlet pipe of the washing machine, the ultrasonic generator 31 is started, and the cleaning water generates a cavitation effect along with the vibration of the vibration plate 33; simultaneously, the water supply pump 52 is started, and the cleaning water is continuously circulated in the cleaning water circulation system; the cleaning water reaches the positions between the inner and outer barrels, electric heating, tripods, corrugated pipes, filter screens and the like, and the dirt on the surface of the cleaning water is damaged and falls off under the action of high pressure.

When the clothes are washed, the ultrasonic generator 31 is started, along with the vibration of the vibration plate 33, the washing water generates cavitation, the solubility of the washing liquid in the water is increased, and simultaneously, dirt on the surfaces of the clothes is damaged and falls off under the action of high pressure.
