ABSTRACT:
Disclosed is an improvement of ultrasonic cleaning system equipped with degassing means or boiling vessel to remove gases from cleaning liquid for activating the formation of cavitation in the cleaning bath. The ultrasonic cleaning system is improved according to the present invention in that the boiling vessel is used to supply the degassed liquid to the cleaning vessel to form a high-temperature zone on the cleaning bath, and that a circulation conduit is provided to supply the cleaning liquid from the high-temperature zone to the bottom of the cleaning vessel. The improved structure permits the creation of a high-temperature zone and a low-temperature or cleaning zone in one cleaning vessel, thereby preventing the dissolution of surrounding gases into the cleaning liquid, and at the same time, subjecting objects to ultrasonic-cleaning at a controlled temperature which is appropriate for ultrasonic cleaning, thereby improving the cleaning effect, and hence the cleaning efficiency.
