Title: Ultrasonic cleaning method and ultrasonic cleaning apparatus
Inventor: UENO SHIGERU
IPC: B08B3/12
Filed: 2001-09-27
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic cleaning method for exhibiting high cleaning ability surely and reducing the pressure load imposed on a cleaning tank. SOLUTION: This ultrasonic cleaning method comprises a vacuum cleaning step to give ultrasonic waves to a solvent under a condition that the cleaning tank is evacuated and an atmospheric pressure cleaning step to give ultrasonic waves to the solvent under another condition that the cleaning tank is kept in atmospheric pressure, which are carried out in this order. The vacuum cleaning step is carried out at several stages by changing the degree of the vacuum of the cleaning tank. High cleaning ability can be obtained even at the atmospheric pressure cleaning step to be carried out subsequently to the vacuum cleaning step since the solvent is kept in the deaerated state to some degree.  Since it is possible to set the deaerated degree of the solvent to a cavitation generating degree at any stage of the vacuum cleaning step to carry out by changing the degree of vacuum, the time to keep the cleaning tank at the maximum degree of vacuum can be made short.
