FINE FOAM GENERATING DEVICE

摘要

PROBLEM TO BE SOLVED: To efficiently generate fine foam by efficiently dissolving air in a liquid without using an expensive circulating pump in a fine foam generating device. SOLUTION: The fine foam generating device is constituted so as to take out bath water from a bath tub 10 to a circulating passage 21 by a circulation pump 22, to dissolve air in the bath water in a gas liquid mixing tank 23 arranged at the downstream side of the circulating pump 22 and to reflux to the bath tub 10. It is not necessary to use an expensive circulating pump excellent in air lock property like the conventional device by forming the device to dissolve the air in the bath water at the downstream side of the circulating pump 22 in this way. Further the air is efficiently dissolved in the bath water by stirring the bath water and the air in the gas liquid mixing tank 23 separated from the atmosphere.
