To start hot water supply from a state where hot water supply is stopped, when the hot water supply switch (not shown) of the setting device 32 is turned on, the flow rate control valve 28 instructs the controller 33 via the flow control valve drive device 29. It is opened upon receipt. The pressures of the hot water and water supplied from the hot water inlet 14 and the water inlet 15 are equalized by the pressure adjusting valve 17 and supplied to the mixing valve 18, and the mixing valve 18 adjusts the mixing ratio of the hot water and water. . Due to the action of the pressure adjusting valve 17, even if the hot water pressure or the water pressure fluctuates, a large fluctuation of the mixed hot water temperature is reduced. The temperature of the mixed hot water is detected by the mixed hot water temperature sensor 26, and the controller 32 compares the mixed hot water temperature set value signal set by the setting device 32 with the detection signal of the mixed hot water temperature sensor 26. Mixing valve drive device 2 to eliminate deviation
5 is controlled to control the temperature of the mixed hot water. Flow sensor 27
Stops the operation of the mixing valve 18 when the amount of mixed hot water falls below a predetermined value to prevent the mixing valve from moving at the time of hot water supply stop operation or at the time of stopping, and further to open the hot water side, and to add the amount of mixed hot water or Instantaneous flow rate detection is also performed to adjust the flow rate. The flow rate adjusting valve unit 28 adjusts the flow rate of the mixed hot water and supplies it to the hot water supply target. Normally, in this way the setting device 32
The mixed hot water having the temperature instructed in 1 is adjusted by the mixing valve 18 and supplied to the hot water supply target.

8. If the pressure regulating valve 17 fails or the mixing valve control circuit (not shown) in the controller 33 fails, the mixed hot water cannot be supplied at the temperature indicated by the setting device 32. Especially when a high temperature is supplied, it may be exposed to hot water, which is dangerous. In such a case, the controller 33 first determines that the mixed hot water temperature detected by the mixed hot water temperature sensor 26 does not reach the temperature set by the setting device 32. Next, it is determined that the temperature deviation is not eliminated even after the predetermined time required for the control operation of the mixing valve 18 is reached, and the flow rate control valve 28 is controlled to be closed via the flow rate control valve drive device 29. Vessel 33 gives instructions. Then, the flow rate control valve 28 stops the supply of the mixed hot water to prevent the supply of the hot water deviated from the set temperature and the supply of the cold water.

The mixed water can be stopped by the flow rate control valve 28 when the temperature exceeds a predetermined value of 50 ° C., which is determined by allowing the temperature to have a certain range.
When the supply of the mixed hot water is stopped, the flow sensor 27 also stops the driving of the mixing valve 18 via the mixing valve driving device 25.

絞れば湯温の立上りを早くすることも可能である。Even before the failure, the mixed hot water temperature may overshoot or undershoot due to a sudden change in the water pressure, the hot water pressure, the flow rate of the supplied mixed hot water, or a sudden change in the supplied hot water temperature. . The water pressure fluctuation and the hot water pressure fluctuation are temporarily equalized by the pressure adjusting valve 17. However, when the pressure adjusting valve fails, or when the pressure fluctuation exceeds the limit, the mixed hot water temperature fluctuates. In such a case, the controller 33 compares the mixed hot water temperature set value signal of the setting device 32 with the mixed hot water temperature signal detected by the mixed hot water temperature sensor 26, and the temperature deviation exceeds a predetermined value such as 3 deg. When is opened, the flow rate is reduced by the flow rate control valve 28. The throttled flow rate is controlled by the controller 33 via the flow rate control valve drive device 29 up to a predetermined deviation value while monitoring the signal from the flow rate sensor 27. At this time, if the supply of the mixed hot water is stopped, dissatisfaction remains because the hot water is used, and since the hot water and water are not supplied, the control of the mixing valve 18 is not performed and a problem remains, so the stop is not performed. In addition, when the flow rate of the mixed hot water is reduced without stopping, the mixed hot water is discharged even though it is a slight amount.Therefore, when there is a transient change in the mixed hot water temperature, when the supply of the mixed hot water is completely stopped. Compare, mixed hot water temperature sensor 26
High-temperature hot water in the vicinity can be discharged quickly, and normal control can be returned quickly. When hot water supply is no longer required, the hot water supply switch of the setting device 32 is turned off, and the flow rate control valve 28 stops the supply of the mixed hot water. It should be noted that the hot water supply can be stopped even if the water heater fails or the stored hot water runs out. Further, when an instantaneous water heater is used, it is possible to speed up the rise of hot water temperature by reducing the flow rate at the initial start.
