Title:
RESONANT OSCILLATION TYPE ULTRASONIC GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/097817
Kind Code:
A1
Abstract:
The present invention relates to an ultrasonic cleaner and, more particularly, a resonant oscillation type ultrasonic generation system which generates ultrasonic waves for contained cleaning water through ultrasonic oscillation to thus perform ultrasonic cleaning, and always oscillates at a constant ultrasonic vibration through frequency adjustment when ultrasonic oscillation efficiency is lowered due to a temperature rise in a vibration oscillation element due to ultrasonic cleaning, the generation of foreign substances, etc. The present invention relates to an ultrasonic cleaner comprising an ultrasonic vibrator (43) provided on one side of a cleaning water container (111) containing cleaning water (112) therein and ultrasonically oscillating, wherein the ultrasonic cleaner has an ultrasonic oscillation unit (20) for generating ultrasonic oscillation in the ultrasonic vibrator (43) provided on one side of the cleaning water container (111), wherein the ultrasonic oscillation unit (20) includes: a main controller (30); a frequency transmitter (41) for transmitting an ultrasonic frequency signal; an amplifier (42) for amplifying a frequency signal; and a scanner (44) including the ultrasonic vibrator (43) and connected between the amplifier (42) and the ultrasonic vibrator (43) to detect an ultrasonic signal; and a current detector (45) connected between the amplifier (42) and the ultrasonic vibrator (43) to detect a current.
