PURPOSE:To enable high pressure air and hot water to be freely selected or mixed and the temperature of mixed air to be freely controlled by providing a control circuit for controlling a air liquid mixing device for mixing or selecting the high pressure air and hot water. CONSTITUTION:Hot water supplied from a hot water supply machine 5 is regulated to flow rate used for a hot water controlling valve 12 in a air liquid mixing device 10 to be sent through a hot water supply pit 6 to a mixing chamber 14. On the other hand, high pressure air supplied from an air compressor 7 is heated to a predetermined temperature by a heater 11 provided on the way of an air transfer pipe 8 and then mixed air amount is regulated by an air controlling valve 13 in the air liquid mixing device 10 to be sent to a mixing chamber 14. Hot water and high pressure air are mixed in the mixing chamber 14 and sent to a shower head 1 through a terminal connecting path 9 to be jetted. If hot water is not used by the hot water controlling valve 12, only high pressure air is jetted through the terminal connecting path 9 from the shower head 1. A signal of a temperature sensor 15 is calculated by a remote control 17 to command heater 11 so that when the hot water and air are mixed the temperature of air can be equalized to that of hot water to jet the hot water of a predetermined temperature.
