ら混合湯が供給される。Next, the operation of this embodiment will be explained. When a hot water supply instruction is issued using the setting device 26, hot water and water begin to be supplied at the opening degree set by the electrically driven flow rate control valve 31. The temperature and flow rate that are commonly used are preset by a single controller, and instructions are given, for example, to set the door to 40 degrees and to open it halfway. For temperature control, the temperature detected by the thermistor 25 is
When the temperature is lower than the set 40 degrees, the controller 1 controls the ratio control valve 18 to increase the flow rate of hot water and reduce the flow rate of water.
9 controls solenoid 38. This operation is performed by increasing the current applied to the solenoid 38, which biases the plunger 39 to the left in FIG. be exposed. On the other hand, if the current value is high, control is performed by reducing the current value to reduce the flow rate of hot water and increase the flow rate of water. Then, the hot water and water are mixed at the confluence section 24, and the mixed hot water is supplied from the hot water supply port 27. Ru.
給湯中に、湯水の圧力変動や流量変更に伴う1次の変動

お変動は極少なくて済む。また、給湯の停止中に流量制
御弁31は閉しられるため、圧力バランス弁33のピス

無くせる。During hot water supply, if there is a primary fluctuation due to pressure fluctuations or changes in the flow rate of hot water, the secondary pressure will change due to the action of the pressure balance valve 33.
Since the difference corresponding to Paiska is kept constant, fluctuations in the mixed water temperature are minimal. Furthermore, since the flow rate control valve 31 is closed while hot water supply is stopped, leakage from the high pressure side to the low pressure side at the piston 37 portion of the pressure balance valve 33 can be eliminated.
また、流量比を調節する比率制御部18と合流部24は
分離されているため、合流部24と給湯口27はきわめ
て近い場所に設置することができ、混合湯の温度を変更
しても直ちに所望の温度が得られる。Furthermore, since the ratio control section 18 that adjusts the flow rate ratio and the merging section 24 are separated, the merging section 24 and the hot water supply port 27 can be installed very close to each other, so that even if the temperature of the mixed hot water is changed, it is immediately The desired temperature is obtained.
また、熱湯を供給した後、温度設定器26で温度を変更
しで低い温度に戻しても、直ちに低い温度が得られるた
め、従来のように温度変更の後すくに給湯口のところに
手を出して、火傷をおうようなことがなくなる。In addition, even if you change the temperature with the temperature setting device 26 and return it to a lower temperature after supplying hot water, the lower temperature will be obtained immediately, so you can quickly reach the hot water supply opening after changing the temperature like in the past. You won't have to take it out and get burned.

Since the solenoid 38, the electric drive unit, and the controller 19 associated therewith can be installed at any location apart from 4, the solenoid 38, electric drive unit, and controller 19 can be installed at a location with a good environment. In particular, since actuators such as the solenoid 38 have moving parts, the controller 19
Since it cannot be molded like the P board, it has the great advantage of not having to be installed near a humid bathroom.

Particularly, if the pipes are buried in a concrete wall near the bathroom, the construction work can be easily completed. Furthermore, since the power supply can be avoided in humid places, there is no need to draw it in at a low voltage, eliminating the need for low-voltage means.

The difference between this second embodiment and the first embodiment is that in this embodiment, a ratio control valve unit (18') is built into the water heater 40, and the water heater 40 controller and ratio control valve unit 18' are built into the water heater 40. The valve 18' is built-in and serves as a controller for the water heater 40 and a ratio control valve 18', and the setting device is separated from the terminal unit 23' and transmits signals by independent radio. It has a setting device 41 with a built-in transmission means, and has a wireless receiver 42 indoors that constitutes a part of the transmission means.

Tell 9'. Possible wireless means include radio waves, infrared rays, and ultrasonic waves. Depending on the condition of the building, the receiving unit
may also be received directly by the controller 19'.

している。Effects of the Invention As described above, the hot water mixing device of the present invention includes a hot water inlet for supplying mixed hot water, a temperature setting device for setting the temperature of the mixed hot water, and a confluence of hot water and water provided near the hot water inlet. A temperature detector installed after this junction to detect the temperature of the mixed hot water, and a hot water that adjusts the flow rate ratio of hot water and water flowing through the hot water side piping and water side piping connected to this junction. A ratio control valve with a water pressure balance function, an electric drive means that applies a bias force to this ratio control valve, and a control that controls the electric drive means by comparing signals from a temperature setting device and a temperature detector. The system is configured with a temperature setting device located near the hot water supply inlet and a signal from a temperature sensor that is wirelessly transmitted directly or indirectly to a controller located near the ratio control valve. Furthermore, since the flow rate control valve is provided upstream of the ratio control valve, it has the following effects.

Also, even if you return the set temperature to a low temperature, you can use it immediately, and the stagnant hot water is supplied, so there is no risk of getting burned. In addition, the ratio control valve and electric drive means can be installed in any location away from the merging section, which increases durability by avoiding moisture, prevents electrical leakage, and allows installation in a location that is easy to maintain. This makes construction easier. Furthermore, since the merging section and the ratio control valve are connected by hot water side piping and water side piping, it is possible to use the existing piping as is for replacement work, by opening the back of the wall or adding or subtracting piping. There is no need for it, and you can choose a location that is easy to install the ratio control valve, making construction easier.
