MICRO BUBBLE GENERATOR AND SHOWER APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a micro bubble generator by which higher washing effect to an object to be washed can be obtained by arbitrarily changing amount of bubbles and a bubble diameter.

SOLUTION: The micro bubble generator is provided with a flow straightening body 9 disposed in a flow straightening tube 8 and a pressure reducing mechanism 2 provided at a downstream side of the flow straightening body 9. The flow straightening body 9 is constituted by stacking a plurality of flow straightening plates 12 of the same shape in which a plurality of openings 11 penetrating from an upstream side to a downstream side are provided and respective flow straightening plates 12 are disposed with shifting in a peripheral direction. From an opening 16 of the flow straightening plate 12 at the most upstream side to an opening 17 of the flow straightening plate 15 at the most downstream side are communicated with each other as a twisted passage 18 and thereby strength of negative pressure produced in the pressure reducing mechanism 2 can be made changeable and the amount of bubbles and the bubble diameter can be easily changed by arbitrarily changing twisting inclination of the twisted passage 18 of the flow straightening body 9.
