<p><P>PROBLEM TO BE SOLVED: To provide an ultrasonic washing apparatus with which an elongated tubular body is to be washed and which is designed so as to suppress a burden mainly to a user as much as possible. <P>SOLUTION: A pressure sensor 32 for detecting a static pressure of liquid inside is disposed on a path of a discharge side drain pipe 7 and an electromagnetic valve 30 is disposed on a path of a water feed pipe 6. A CPU (central processing unit) receives an output from the pressure sensor 32, recognizes the level height of liquid stored in a vessel 2, opens/closes the electromagnetic valve 30 in accordance with the recognition result and drives/stops an ultrasonic vibrator 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
