<P>PROBLEM TO BE SOLVED: To provide a bubble generator for improving quality in bubbles that allows a discharge jet including minute bubbles to reach a long distance and generates bubbles of better quality. <P>SOLUTION: A columnar cylindrical object 13 is arranged at a front position of a discharge nozzle 15 where the discharge jet including minute bubbles is discharged into a bath B. The cylindrical object 13 is set so that both the ends are semispherical and a base end part of the cylindrical object 13 is positioned on an open end face of a throttle opening part 152 of the discharge nozzle. The cylindrical object 13 is formed to be of size corresponding to a negative pressure region generated, at a region near a center axis X, immediately after exiting the discharge nozzle of the discharge jet F. The cylindrical object 13 is supported by a support leg and a support arm not shown in the figure on a body housing 12. Also, when a scattering prevention plate is attached to a front position of the discharge nozzle 15, the cylindrical object 13 may be supported on the scattering prevention plate by the support arm through the inside of an opening. <P>COPYRIGHT: (C)2012,JPO&INPIT |
