Abstract
An ultrasonic washing machine as an air bubble supplying device and an ultrasonic generator. The ultrasonic generator works with textile products such as fabrics, yarns, ropes, etc. placed in a tub filled with water. Air bubbles produced by the cavitation effect of the ultrasound cling to the surface of the textile products and help remove stains, alien matter, etc. adhering to them. Part of the air, fed from the outside by an air bubble supplying device, constantly dissolves in the water, whereby the air consumed by the cavitation is supplemented; the rest of the air, not dissolved in the water, diffuses the ultrasound when ascending in the water as bubbles, which serves to greatly improve the washing effect.
Claims9
An ultrasonic washing machine for washing articles, said machine comprising:
- a metal tub having a bottom and an open upper end through which the articles to be washed are placed in said tub, and fluid inlet means through which water is supplied to said tub;
- an ultrasonic generator fixed to and within said tub for generating ultrasound in the water supplied to said tub through said fluid inlet means;
- and
- bubble supplying means at the bottom of said tub for supplying and dispersing air bubbles throughout the water supplied to said tub some of which dissolve in the water to replace air that has been removed from the water due to cavitation when said ultrasonic generator generates ultrasound and the remainder of which reflects the ultrasound to diffuse the ultrasound throughout said tub onto the articles to be washed in said tub.
