MICRO-BUBBLE GENERATING DEVICE AND BATH SYSTEM

摘要

PROBLEM TO BE SOLVED: To stably generate micro-bubbles of a high concentration by a simple small device and prevent bubbles having a large diameter from being generated from a gas-liquid mixing tank. SOLUTION: A micro-bubble generating device has an orifice fixed valve 7 for sucking air installed on a suction pipe 4 for sucking water 5 by a pump 1, the gas-liquid mixing tank 10 in which the water 5 from the pump 1 is introduced and stirred and a pressure detector 18 for detecting the pressure of an air phase A' in the upper part of a mixing chamber 13 of the gas-liquid mixing tank 10. The device is further provided with a controller 19 to which the detection pressure 18a of the pressure detector 18 is inputted for executing the control of setting the pump 1 at a discharge pressure to keep the pressure at which all the air phase A sucked through the orifice fixed valve 7 is dissolved in the water in the gas-liquid mixing tank 10 when the temperature of the water is the highest using temperature.
