ULTRASONIC CLEANER

摘要

There is provided an ultrasonic cleaner for ultrasonic-cleaning stains attached to a surface of an object to be cleaned by using a cleaning liquid to which ultrasonic wave is applied. The ultrasonic cleaner includes: a cleaning tab for containing the cleaning liquid; a support table for supporting the object to be cleaned in the cleaning liquid; ultrasonic wave generation means for alternately converging a first ultrasonic wave having frequency of 1 to 10 MHz and a second ultrasonic wave having frequency of 1/2 of the first ultrasonic wave or below toward the object to be cleaned; converging position adjustment means for adjusting the distance from the converging position of the conversion to the surface of the object to be cleaned; and moving means for moving at least one of the ultrasonic wave generation means and the support table so that the effect of the ultrasonic wave obtained by the ultrasonic wave generation means is applied to the entire surface of the object to be cleaned.
