<p><P>PROBLEM TO BE SOLVED: To provide a nozzle shower type ultrasonic cleaning apparatus which is constituted so that a liquid is discharged from a nozzle having an ultrasonic wave radiating plane therein and brought into contact with a part to be cleaned of a living body, or the like, to form a propagation route of an ultrasonic wave and the part to be cleaned is cleaned while being vibrated ultrasonically and the cleaning efficiency of which is improved. <P>SOLUTION: An end plate 13 folded back inward is arranged in a discharge port 12 of the nozzle 3. Before the part to be cleaned is cleaned in an ultrasonic cleaning mode, a liquid storage mode is set so that the discharge amount of the liquid in the liquid storage mode is made smaller than that of the liquid in the ultrasonic cleaning mode, and a drive circuit 6 controls the flow rate of the liquid in the same manner. Therefore, the liquid is stored in a storage space 11 owing to the control of the flow rate of the fluid in the liquid storage mode and the folded-back part of the end plate and jetted from the discharge port 12 when the storage space is filled with the liquid. As a result, when the part to be cleaned is cleaned in the ultrasonic cleaning mode, the part to be cleaned can be cleaned efficiently since an air bubble being a cause of attenuation of the ultrasonic wave is removed from the propagation route of the ultrasonic wave. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
