The water valve body 7 and the hot water valve body 10 are each formed into a tapered shape, are located inside the water side flexible orifice 5 and the hot water side flexible orifice 6, and are moved in the vertical direction in FIG. The passage area with the orifice can be adjusted. The water side flexible orifice 5 and the hot water side flexible orifice 6 are fixed in the valve body 1, and when fluid flows into the orifice, the pressure difference causes the fluid to deform inward as shown in FIG. 2, reducing the passage area. becomes smaller. This amount of deformation has a certain relationship with the differential pressure, so if the pressure on the water or hot water side increases and the amount of water or hot water attempts to increase, the differential pressure will increase, the amount of deformation will increase, and the passage area will decrease. It has the effect of suppressing the increase in flow rate, resulting in the relationship between water pressure and flow rate as shown in FIG. Figure 3A shows the case where the valve element in the orifice is located on the lower side and the passage area is small (if this is the case, B is the case where the valve element is located on the upper side and the passage area becomes large.Water drive device 1

持するので混合温度と水量は変化せず安定である。Next, the operation will be explained with reference to FIG. 1 and FIG. 4. When hot water supply is started by setting the set temperature and the set water amount in the temperature setting section 21a and the water amount setting section 21b, respectively, the mixing path 4
The temperature and water amount are detected by the temperature detector 19 and the water amount detector 20, and compared with the signals from the temperature setting section 21a and the water amount setting section 21b by the temperature control section 21c and the water amount control section 21d, respectively, and the respective signals are The signal is transmitted to the drive control section 21e. The drive control unit 21e determines the driving direction and driving speed of the water driving device 13 and the hot water driving device 14 according to the temperature of the mixing path 4 and the deviation from the set value of the water amount, and sends out the water. - As an example, we will discuss the case where the mixing temperature is higher than the set temperature and the amount of water is large. Since the temperature is high and the amount of water is large, the drive control unit 21e determines that the amount of hot water in the hot water passage 3 side is large, and first drives the hot water drive device 13 to drive the hot water valve body 10 downward and connects the hot water side flexible orifice 6. The passage area will decrease and the amount of hot water will also decrease. This control operation is continued until the deviation between the temperature setting section 21a and the temperature detector 17 is almost eliminated, and when the temperature deviation is eliminated, the water amount deviation between the water amount detector 20 and the water amount setting section 21b is calculated by the water amount control section 21d. If the actual amount of water is larger than the set amount of water, the water valve body 7 and the hot water valve body 10 of the water drive device 13 and the hot water drive device 14 are simultaneously displaced downward to reduce both the water amount and the hot water amount. This control operation continues until the water amount deviation disappears. i.e. water drive device 1
3 and the hot water drive device 14 are operated independently,
Temperature and water volume are each adjusted according to the set values. In this state, even if the pressure in the water passage 2 or the hot water passage 3 suddenly changes, the water side flexible orifice 5 or hot water side flexible orifice 6 deforms according to the water flow and maintains a constant flow rate, so that mixing is possible. The temperature and water amount remain stable without changing.
