ULTRASONIC CLEANING APPARATUS

PROBLEM TO BE SOLVED: To provide an ultrasonic cleaning apparatus capable of irradiating a cleaning object with an ultrasonic wave more effectively.SOLUTION: An ultrasonic cleaning apparatus 10 includes an ultrasonic vibrator 30 for generating an ultrasonic wave, a cleaning tank 21 in which a surface facing to a vibration surface 30A of the ultrasonic vibrator 30 is formed of a parabola surface 21A forming a recess to the vibration surface 30A, and an outer tank 22 for storing the cleaning tank 21. Further, a damping material 23 is filled between an outer peripheral surface of the cleaning tank 21 and an inner peripheral surface of the outer tank 22.SELECTED DRAWING: Figure 1 【課題】洗浄対象物に対して超音波をより効果的に照射することのできる超音波洗浄装置を提供する。【解決手段】超音波洗浄装置１０は、超音波を発生する超音波振動子３０と、超音波振動子３０の振動面３０Ａに対向する面が振動面３０Ａに対して凹をなすパラボラ面２１Ａで形成されている洗浄槽２１と、洗浄槽２１を収容する外槽２２とを備えている。そして洗浄槽２１の外周面と外槽２２の内周面との間に制振材料２３を充填する。【選択図】図１
