ABSTRACT:
An ultrasonic washing machine for tableware is provided with an ultrasonic generator and an air bubble supplying device in a tub. Air bubbles are sent out from holes of an air bubble supplying device to reflect ultrasound when ascending in water in the tub. Other air bubbles dissolve in the water, but arise on the tableware again by the cavitation effect of the ultrasound, which makes dirt or alien matters release from the tableware. The air in the water consumed by the cavitation of the ultrasound is fed into the water from outside from time to time. Therefore, cleaning of the tableware by air bubbles is carried out constantly and no detergent is needed in washing the tableware.
