ABSTRACT:
Ultrasonic waves of a low frequency and a high frequency are alternately emitted from one vibrator to liquid in a tank, cavitation generated due to the ultrasonic wave of the low frequency is eliminated and changed to small cavitation for forming the next large cavitation due to the ultrasonic wave of the high frequency and next the ultrasonic wave of the low frequency is emitted to the liquid in a tank and large cavitation is formed, whereby the cleaning effect is improved.
