HOT WATER/WATER MIXING AND DISCHARGING DEVICE

PURPOSE:To adjust the discharge water quantity at high speed when a normal discharge water switch is turned on by providing plural pieces of normal discharge water switches whose discharge water quantity is different, and adjusting a throttle valve to an intermediate value of the discharge water quantity corresponding to said plural switches, when said switches are turned off. CONSTITUTION:To normal discharge water switches 21, 22, each corresponding discharge water quantity is preset in advance, and when the switches 21, 22 are turned off, a throttle valve 6 for adjusting the discharge water quantity is adjusted in advance to an intermediate value of said two preset values. When the switches 21, 22 are turned on, an opening/closing valve 8 is opened, and by a flow rate sensor 11, the discharge water quantity is brought to feedback control. In such a case, since the throttle valve 6 is set in advance to the intermediate value of the discharge water quantity corresponding to the normal discharge water switch, it will sufficient that the adjustment width when the discharging water is small, and accordingly, the water discharge quantity can be adjusted at high speed.
