Next, the operation and operation of the above embodiment will be described. First, the setting device 28 installed near the hot water faucet 15
It is assumed that the hot water temperature is set by and the hot water tap 15 is opened. By opening the hot water supply faucet 15, first the hot water supply pipe 14
The cold water staying at the terminal flows into the terminal water heater 16. The cold water supplied to the terminal water heater 16 flows into the hot water storage tank 20 through the inlet flow passage 18, and the high temperature water heated and stored in the hot water storage tank 20 by the heating device 17 is primarily mixed through the outlet flow passage 19. It is extruded into the flow path 22. On the other hand, in parallel with this, the cold water that has flown into the bypass flow channel 21 that is provided by branching from the inlet flow channel 18 flows into the primary mixing flow channel 22 and is approximately the same as the high temperature water supplied from the hot water storage tank 20. It is mixed at a ratio of 1: 1. Further, the hot water obtained by mixing the cold water and the high-temperature water and the cold water supplied from the cold water inflow passage 23 respectively merge in the secondary mixing passage 25 through the mixing ratio varying means 24, and then reach the temperature detector 26 to detect the hot water outlet temperature. To be done.
The hot water temperature detected by the temperature detector 26 is controlled by the controller 27.
And the temperature is compared with the temperature set by the setting device 28, and the controller 27 controls the mixing ratio varying means 24 so as to eliminate the temperature deviation.

When the hot water from the main hot water supply heat source device 13 is supplied to the hot water supply pipe 14 some time after the start of hot water discharge, the temperature of the hot water flowing through the primary mixing flow path 22 rises, but the mixing Since the ratio varying means 24 varies the mixing ratio of the hot water and the cold water so as to reach the set temperature, the hot water tap 15 always supplies hot water having a stable temperature as set. That is, only by setting the setting device 28, hot water having a stable temperature can be obtained immediately after the start of hot water discharge. Further, the controller 27 not only drives the mixing ratio varying means 24, but also controls the heating device 17 so as to maintain the temperature of the high-temperature water stored in the hot water storage tank 20, and further, the setting device 28 controls the setting device 28. Water heater 1
Since it is connected to 6 only by electric wiring, wiring and piping construction is easy, and there is no need to provide a mixed water faucet, and the surroundings of the hot water supply faucet 15 can be made aesthetically clean.

Considering, for example, the case where a conventional hot water supply controller having an immediate hot water function and an electronic mixing tap are used in combination, the pipes of the hot water supply control device and the electronic mixing tap, and the electronic mixing tap and the hot water tap are connected. Piping is required. Further, considering the electric wiring, it is obvious that the hot water supply control device and the electronic mixing tap require a power source section and electric wiring work, respectively, and the workability of the hot water supply control device of the above embodiment is good. Even if a wax-type mixed faucet is adopted as a hot water supply faucet, it is hard to say that the area around the hot water supply faucet is aesthetically neat because the number of man-hours for piping work is increased and the mixed water faucet is large. . Here, if the setting device 28 and the terminal water heater 16 are wirelessly configured, the workability is further improved.

Further, the hot water supply control apparatus of the above-mentioned embodiment has the above-mentioned structure, and by sending a signal from the controller 27 to the pilot pressure varying means 42, the water pressure in the cold water inflow path 23 is guided to the hot water side pressure piston 36 or the water side pressure. It is possible to switch between guiding to the piston 37 and to adjust the conduction area between the hot water pilot pressure introducing passage 40 and the water pilot pressure introducing passage 41 and the cold water inflow passage 23. As a result, the mixing valve body 30 is moved to generate hot water. The flow rate of cold water can be changed. That is, when the hot water supplied from the secondary mixing flow path 25 and the cold water supplied from the cold water inflow path 23 reach the mixing valve body 30, respectively, the hot water valve body 31, the water valve body 32, the hot water pressure piston 36, the water Pressure is applied to each of the side pressure piston 37 and the partition piston 35, and acts so as to maintain a certain flow rate ratio by the force balance action. Here, when a signal is sent from the controller 27 to drive the pilot pressure varying means 42 and the conduction areas of the hot water pilot pressure introducing passage 40 and the water pilot pressure introducing passage 41 and the cold water inflow passage 23 are varied, the hot water pressure piston The pressure acting on 36 and the water side pressure piston 37 changes, and the mixing valve body 30 moves to a position where the force balance can be maintained. As a result, the flow ratio of hot water and cold water is variable.

For example, if the pilot pressure varying means 42 increases the communication opening degree between the cold water inflow passage 23 and the water side pilot pressure introducing passage 41 and decreases the communication opening degree between the hot water side pilot pressure introducing passage 40, As the amount of water flowing from the inflow passage 23 to the water side pilot pressure introducing passage 41 increases, the pressure acting on the water side pressure piston 37 also increases, and the amount of water flowing into the hot water pilot pressure introducing passage 41 decreases. The pressure acting on the molten metal pressure piston 36 also decreases. Therefore, the mixing valve body 30 maintains the equilibrium at the position where the water side valve body 32 is closed and the hot water side valve body 31 is opened, and the hot water and cold water flow ratio is such that a large amount of hot water is mixed with cold water. On the contrary, when the pilot pressure varying means 42 increases the communication opening degree between the cold water inflow passage 23 and the hot water pilot pressure introducing passage 40 and decreases the communication opening degree with the water side pilot pressure introducing passage 41, the cold water inflow passage 2
3, the pressure acting on the hot water pressure piston 36 increases with an increase in the amount of water flowing into the hot water pilot pressure introducing passage 40, and the amount of water flowing into the hot water pilot pressure introducing passage 41 decreases. The pressure acting on the side pressure piston 41 is also reduced. Therefore, the mixing valve body 30 is the hot side valve body 31.
Is closed and equilibrium is maintained at the position where the water side valve body 32 is opened, and a large amount of cold water is mixed with warm water as a flow ratio of hot water and cold water.

In this way, the pilot pressure varying means 42 is driven by the signal from the controller 27 to vary the communication opening degree of the cold water inflow passage 23, the hot water pilot pressure introducing passage 40 and the water side pilot pressure introducing passage 41. With this, the flow rate ratio of hot water and cold water can be varied. Moreover, the flow passage areas of the hot water pilot pressure introduction passage 40 and the hot water pilot pressure introduction passage 41 have the hot water valve body 31, the hot water valve body 32, the partition piston 35, the hot water pressure piston 36, and the hot water pressure piston 3 respectively.
Since it is significantly smaller than the pressure receiving area of No. 7, the driving force required for the pilot pressure varying means 42 can be reduced accordingly. Therefore, the pilot pressure varying means 42 can be small in size and compact with low power consumption. That is, by driving the pilot pressure varying means 42 with a signal from the controller 27, the pressure acting on the hot water pressure piston 36 and the hot water pressure piston 37 changes. Along with this, the mixing valve body 30 can be moved by the force balancing action, and the mixing ratio of hot water and cold water can be varied. Moreover, it becomes possible to make the mixing ratio varying means 24 constituting the terminal water heater 16 small in size and compact with low power consumption.

In the hot water supply control apparatus of the above embodiment, the water pressure of the cold water inflow passage 23 is controlled by controlling the stepping motor 46 by the instruction of the controller 27 for the rotational angle position of the pilot valve shaft 43. Side pressure piston 3
6 or switching to the water pressure piston 37, and the conduction area between the hot water pilot pressure introducing passage 40 and the water pilot pressure introducing passage 41 and the cold water inflow passage 23 can be changed. For example, when the stepping motor 46 turns around the pilot valve shaft 43, the cutout flow passage 44 formed in the pilot valve shaft 43 turns its back to the hot water pilot pressure introducing passage 40 and the water side pilot pressure introducing passage 41. When the degree of increase first increases, the cold water inflow path 23 and the hot water pilot pressure introducing path 40 are closed, and the conduction area between the cold water inflow path 23 and the water side pilot pressure introducing path 41 increases. That is, the water flow from the cold water inflow passage 23 passes through the cutout passage 44 of the pilot valve shaft 43, further passes through the water side pilot pressure introducing passage 41, and reaches the water side pressure piston 37. This is because the cutout passage 44 expands toward the water-side pilot pressure introduction passage 41. Then, the working pressure on the hot water pressure piston 36, which tends to push the hot water valve body 38 toward the hot water valve seat 38, decreases, and the hot water valve body 32 pushes the hot water valve body 32 toward the hot water valve seat 39. The working pressure on the water side pressure piston 37 increases. On the contrary, the stepping motor 46 turns around the pilot valve shaft 43, and the cutout flow passage 44 formed in the pilot valve shaft 43 turns its back to the water side pilot pressure introduction passage 41 and is applied to the hot water side pilot pressure introduction passage 40. When the degree of increase first increases, the communication between the cold water inflow passage 23 and the water side pilot pressure introduction passage 41 is closed, and the conduction area between the cold water inflow passage 23 and the hot water pilot pressure introduction passage 41 increases. Then, the working pressure on the water-side pressure piston 37, which tends to push the water-side valve element 32 toward the water-side valve seat 39, decreases, and the hot-water valve element 31 pushes toward the hot-side valve seat 38. The working pressure on the hot water pressure piston 36 increases. As described above, the force balance action moves the mixing valve body 30 to change the flow rate ratio of the hot water and the cold water. Since only one thin pilot valve shaft with a diameter of about 2 to 3 g is rotationally controlled in this way, an extremely small rotational driving force of about 0.1 torque is sufficient even if the O-ring is sealed. As the actuator, it is possible to control the flow rate ratio of hot water and cold water by providing only one small stepping motor 46 with low power consumption.
