<p>PURPOSE:To improve the safety and the response of the titled device and to obtain a predetermined quantity of water by carrying out the actuation stop of a mixing valuve, at the time of stopping the hot water supply, to stop the supply of mixed hot water when the operated value of the mixed hot water quantity reaches a predetermined value. CONSTITUTION:In the state where a cock 21 is opened, temperature setting signal is compared with the signal of a mixed hot water temperature in a controller 24, and a mixing valve 36 is actuated to the position where the deviation of both signals becomes zero. When the cock 21 is closed, the flow quantity detector detects that the flow has been stopped, and stops the operation of a motor through the controller 24. For this reason, after the stop of hot water supply, even when the temperature of the temperature detector part is lowered by cooling, the mixing valve 36 does not act to open the hot water side and throttle the water side. At the time of resupplying hot water, when the cock 21 is opened, a flow is generated. The flow quantity detector detects the generation of the flow, and current is supplied to the motor. Accordingly, at the tmie of resupplying hot water, hot water is not supplied temporarily. Furthermore, when an integrated value of the mixed hot water quantity to a bathtub is set in a hot water supply controller 23, to set the mixed hot water temperature, and the cock 21 is opened, the mixing valve 36 starts the mixing operation and, at the same time, the flow quantity is commenced to be integrated in the controler 24, and a control valve 42 is closed under an instruction from the controller 24 to reach the set value.</p> |
