PROBLEM TO BE SOLVED: To discharge soda water controlled in carbon dioxide gas concentration.SOLUTION: Carbon dioxide gas G of a constant quantity per unit time is determined from a command of ON by a foot switch 5 by the first function in a control board 15, and a carbon dioxide gas G quantity itself per unit time determined by the first function is increased/decreased based on a mode selected from a mode selection switch by the second function, and the carbon dioxide gas G quantity per unit time determined by the second function is adjusted based on a pressure measurement value detected by a supply line side pressure sensor 34 by the third function. A solenoid valve 16 is controlled, for example, to supply no carbonic acid when the pressure measurement value detected by the supply line side pressure sensor 34 is a predetermined value or less, to set a quantity obtained by multiplying the carbon dioxide gas G quantity by a factor α when the pressure measurement value is equal to or more than the predetermined pressure and less than a second predetermined pressure, and to set a quantity obtained by multiplying the caron dioxide gas G quantity by a factor β when the pressure measurement value is equal to or more than the second predetermined value, and soda water S of the controlled carbon dioxide gas G concentration is discharged from discharge means 4.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】炭酸ガス濃度が制御された炭酸水を吐出可能とする。【解決手段】制御基板15において第1の機能により、フットスイッチ5によるオンのコマンドから、単位時間当たり一定量の炭酸ガスGを決定し、第2の機能により、モード選択スイッチから選択されたモードに基づき、第1の機能で決定した単位時間当たりの炭酸ガスG量そのものを増減し、第3の機能により、供給ライン側圧力センサ34が検知した圧力測定値に基づき、第2の機能で決定した単位時間当たりの炭酸ガスG量を調整し、例えば、供給ライン側圧力センサ34が検知した圧力測定値が、所定圧以下であれば炭酸を供給せず、所定圧以上、第二所定圧未満であれば上記炭酸ガスG量に係数αを乗じた量とし、第二所定圧以上であれば上記炭酸ガスG量に係数βを乗じた量とするように電磁弁16を制御し、制御された炭酸ガスG濃度の炭酸水Sを吐出手段4から吐出する。【選択図】図1
