Abstract

PURPOSE: To effectively transmit ultrasonic waves to the inside of material to be washed without the ultrasonic wave being damped in a washing tank only by soaking the bottom of the material to be washed into water in the washing tank in order to effectively when the inside of a vessel or the like as a matter of priority by using ultrasonic waves, and also to simplify the handling of the material to be washed. CONSTITUTION: A washer consists of a washing tank 1 consisting of an ultrasonic washing tank 2 having an ultrasonic vibrator transducer 3 and an overflow tank 4 placed adjacent to the ultrasonic washer 2, a circulation pump 7, transfer piping 8 and return piping 9. At the upper end of the sidewall between the ultrasonic washing tank 2 and the overflow tank 4, notches are formed, and the circulation pump 7 is operated to circulate washing water in the ultrasonic washing tank 2. The washing water is caused to flow out by gravity from the notches while the free surface is kept above to form weirs 5. A bottom guide plate 6 placed at the lower edges of the weirs 5 is fitted as a bridge between both the weirs 5.
