ABSTRACT:
Disclosed is an improvement of ultrasonic washing apparatus comprising at least one washing vessel, an ultrasonic vibrator for radiating ultrasonic wave into the washing bath, an oscillator for operating the ultrasonic vibrator and degassing means for removing dissolved air and other gases from the washing liquid, thereby enhancing cavitation in the washing bath when the ultrasonic wave is radiated therein, said degassing means including gas separating means and barrier means for preventing surrounding air from dissolving into the washing liquid while it is degassed. Thanks to deaeration in the washing bath cavitation can be used to its full extent in removing soil from a soiled object in the washing bath.
