されることにより、流量が一定化される。In the figure, the hot water and water supplied through the hot water flow path 15 and the water flow path 16 are controlled in flow rate by a constant flow valve 17 on the hot water side and a constant flow rate valve 18 on the water side. The constant-flow hot water and water are made up of hot water, a valve seat 22, and a valve shaft 23 that finely adjust the flow rate and stop the water. The hot water side valve 19 and the water side valve 20 are operated by a hot water side motor 24 and a water side motor 2, which are independent electric driving means.
5. Hot water side motor 24 and water side motor 25
The rotation of both is caused by the reduction gear 26 and the linear motion conversion mechanism 2.
7, it is decelerated and converted, and is transmitted to the hot water side valve 19 and the water side valve 20. The temperature of the mixed water that has been merged and mixed is detected by the thermistor 28. Also, the mixing flow rate is determined by the flow rate sensor 2.
Detected by 9. The mixed hot water flows through the mixed hot water flow path 30.
The hot water is then supplied from the faucet 31 to the hot water supply target. A setting device 32 is provided near the faucet 31 for setting the start and stop of hot water supply, the mixed water temperature, the mixed flow rate, and the integrated value of the mixed flow rate, as well as displaying their current values. The signals from the thermistor 28, flow rate sensor 29, and setting device 32 described above are transmitted to the controller a3, and the controller 33 controls the hot water side motor 24, the water side motor 26, and the setting device 32. FIG. 2 shows the detailed configuration of the hot water side constant flow valve 17 and the water side flow valve 18. A rubber constant flow valve element 35 is held in the holding cylinder 34, and the opening area of the opening part 36 of the holding cylinder 34 is adjusted by the adjusting part a7 of the constant flow valve element a5 which bends depending on the magnitude of the flow rate. , the flow rate is made constant.

混合水や汚水が逆流することが防止できている。The flow path on the hot water side and the flow rate on the water side are roughly determined by the hot water side constant flow valve 17 and the water side constant flow valve 18, but if the pressure is higher or lower than the design value, the flow rate will slightly change to the set value. It comes off. Therefore, the mixed water temperature and mixed flow rate differ from the values set by the setting device 32. This difference is corrected by electrical feedback control. That is, the mixed water temperature detected by the thermistor 28 and the mixed water temperature set by the setting device 32 are compared by the controller a3, and the controller 33 controls the hot water side motor 24 and the water side motor 25 to eliminate the deviation between the two.
control and finely adjust the mixing ratio. Similarly, the mixed flow rate detected by the flow rate sensor 29 and the setting value of the setting device 32 are compared by the controller 33, and the mixed flow rate is finely adjusted. The signals from the thermistor 28 and the flow rate sensor 29 are displayed on the setting device 32 via the controller 33. In addition, when flow rate integration is instructed by the setting device 32, the signal from the flow rate sensor 29 is integrated by the controller a3, and when the predetermined flow rate is reached, the hot water side valve 19 and the water side valve 20 are closed to stop hot water supply. . If another faucet or hot water supply faucet is used during use and the primary pressure of hot water or water changes greatly, the flow rate of hot water or water will also change greatly, but the hot water side constant flow valve 17 and the water side constant flow valve 18 This function keeps the flow rate almost the same as before the change, and prevents the mixed water temperature and mixed flow rate from changing significantly. At this time, minute changes in the mixed water temperature and mixed flow rate are detected by the thermistor 28 and flow rate sensor 29 and finely adjusted as described above. In addition, during use, if the primary pressure is high at the hot water side constant flow valve 17 or the water side constant flow valve 18, the pressure is reduced as a result, so the pressure applied to the hot water side valve 19 or the water side valve 2° is reduced. Therefore, the hot water side motor 24 and the water side motor 25 need only have small capacities, and the amount of electricity consumed can be reduced. Further, since the hot water side constant flow valve 17 and the water side constant flow valve 18 allow the flow rate to be approximately above the window and a large flow rate does not flow, it is possible to reduce erosion of the flow path which increases proportionally with the flow velocity. When you want to stop hot water supply, you instruct the hot water supply stop using the setting device 32, and the hot water side motor 24 controls the hot water side valve 19, and the water side motor 25 causes hot water or water to enter from the side with higher water pressure to the side with lower water pressure. In addition, it is possible to prevent mixed water and sewage from flowing back from the faucet 31 side during a water outage.

される形式をとっている。The advantage of this embodiment is that, as described above, the hot water side valve 19 and the water side valve 20 are driven and controlled by the hot water side motor 24 and the water side motor 25, which are independent electric drive means, respectively. The structure is simple, and the point that it prevents hot water or water with higher pressure from penetrating into the lower pressure one, and prevents backflow when water is cut off, is commendable. Further, the hot water side constant flow valve 17 and the water side constant flow valve 18 utilize the flexure of rubber that deforms depending on hot water pressure or water pressure, so they do not require a special spring and have the effect of simplifying the structure. FIG. 3 shows another embodiment of the present invention, which includes an intestinal measurement flow valve 41 constituted by a valve body 40 connected to a piston 39 that moves based on the differential pressure across the orifice a8, and a water side constant flow valve. It has 42. The mixing valve 43 has a hot water side valve body 44 and a water side valve body 45 connected to a shaft 46.
The mixing valve motor 47 is provided in an external mixing valve motor 47 and driven by an external mixing valve motor 47.

The functions of the hot water side constant flow valve 41 and the water side constant flow valve 42 in this embodiment are the same as in the first embodiment, so a detailed explanation will be omitted.

The idea of the present invention can also be applied to feedforward control in which the mixed water temperature is determined by calculation, and a system in which the temperature setting of a mixing valve whose temperature is regulated by a wax thermometer is changed by a motor.
