えられる。In FIG. 1, the hot water and water that have entered the valve frame body 16 from the hot water inlets 14 and 15 reach a mixing valve 18 via a pressure adjusting valve 17 that adjusts the pressures of the two and equalizes them. Mixing valve 18 is the hot side valve body
19 and a water side valve body 20 is a motor 22 provided outside through a shaft 21,
Drive device consisting of gear box 23 and linear motion conversion mechanism 24
Driven by 25. Then, the mixing ratio of the hot water and the water is changed by the mixing valve 18, and the hot water temperature of the hot water mixed with the hot water is detected by the hot water sensor 26. The amount of mixed hot water is detected by the flow rate sensor 27. The mixed water continues to flow control valve 28
The flow rate is adjusted and limited by the flow rate control valve 28, and the flow rate control valve 28 is driven by a flow rate control valve drive device 29 having the same configuration as the external mixing valve drive device 25. Finally, the mixed hot water is supplied from the mixed hot water outlet 30 through the hot water supply target outlet 31.
A setting device 32 that sets the temperature of the mixed hot water and instructs the supply / stop of the mixed hot water is provided near the discharge port 31.
The signal from the setter 32 is taken into the controller 33. Controller
The signals taken in by 33 are the signals of the flow rate sensor 27 and the signal of the mixed hot water temperature sensor 26, and the output signal is transmitted from the controller 33 to the mixing valve drive device 22 and the flow rate control valve drive device 29.

ないこと制御器33がまず判断する。Next, the operation will be described. To start hot water supply when 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 causes the flow rate control valve drive device.
It is opened by receiving a command from the controller 33 via 29. Hot water and water supplied from the hot water inlet 14 and the water inlet 15 are pressure regulating valves.
The pressure is equalized at 17 and the mixing ratio of hot water and water is adjusted at the mixing valve 18. The mixed 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 signal of the mixed hot water temperature sensor 26 to eliminate the deviation between both signals. Thus, the mixing valve drive device 25 is drive-controlled to adjust the temperature of the mixed hot water. The flow rate sensor 27 serves to stop the operation of the mixing valve 18 when the temperature of the mixed hot water falls below a predetermined value, and
Instantaneous value detection is performed to integrate the temperature of the mixed hot water and adjust the flow rate of the mixed hot water. The flow rate control valve unit 28 regulates the flow rate of the mixed hot water and supplies it to the hot water supply target. Normally, the mixed hot water having the temperature designated by the setting device 32 is supplied in this manner. In the unlikely event that the mixing valve drive device 25 or the mixing valve 18 fails, the controller 33
If the mixing valve control circuit (not shown) therein fails, the mixed hot water cannot be supplied at the temperature instructed by the setter 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 set value set by the setting device 32.

湯を停止させている。Next, it is determined that the temperature deviation is not resolved even after the predetermined time required for the control operation of the mixing valve 18, and the flow rate control valve 28 is controlled to be closed via the flow rate control valve drive device 29. Unit 33 gives a command. The flow rate control valve 28 stops the supply of the mixed hot water to prevent the supply of hot water and the supply of cold water. Particularly dangerous is that hot water is supplied and bathed in the body. As a countermeasure against this, when the object to be supplied with the mixed hot water is a shower, the mixed water is stopped by the flow rate control valve 28 when it exceeds the predetermined value 50 ° C, which is set with a certain width to the upper limit value of 45 ° C that is normally used. There is.

混合弁18の制御も行なわれなくなり問題が残るので、停
止はさせていない。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. In such a case, the controller 33 compares the mixed hot water temperature set value signal of the setting device 32 and the mixed hot water temperature signal detected by the mixed hot water temperature sensor 26, and the deviation width becomes equal to or larger than a predetermined value, for example, 2 deg. Opens and the flow control valve
At 28, the flow rate is extremely reduced and reduced. The throttled flow rate is controlled by the controller 33 via the flow rate control valve drive device 29 to a predetermined value while monitoring the signal of the flow rate sensor 27. At this time, if the supply of the mixed hot water is stopped, dissatisfaction will remain because it is still in use, and since the mixing valve 18 will not be controlled because hot water and water will not be supplied, a problem remains, so it has not been stopped. .

の立ち上りを早くすることが可能である。When hot water supply is finally unnecessary, the hot water supply switch of the setting device 32 is turned off, and the flow rate control 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 comes out. Further, when using an instantaneous water heater, it is possible to speed up the rise of the water temperature by reducing the flow rate at the initial start.

信号が、通常使用される温度の上限値に幅を持たせて設
定した所定値を越えた場合、混合湯を停止できるため、
危険温度を偏差としてでなく絶対値として定められる効
果を有する。In this embodiment, the controller 33 can stop the mixed hot water when the signal of the mixed hot water temperature sensor 26 exceeds a predetermined value set with a width in the upper limit value of the normally used temperature.
It has the effect that the critical temperature is defined as an absolute value rather than a deviation.
