る。[Detailed explanation of the device] This device switches to the heater when the hot water temperature in the solar collector is lower than the set value, and also supplies tap water to the heater when the hot water temperature is lower than the tap water temperature. This is how it was done.
従来、太陽熱温水器における自動給排水装置と
して特公昭53−20702号公報の第１図（本願図面
の第５図）のものがある。 Conventionally, as an automatic water supply and drainage device for a solar water heater, there is a device shown in FIG. 1 of Japanese Patent Publication No. 53-20702 (FIG. 5 of the drawings of the present application).

によつて作動するものであるから予じめt1を配置
しておかなければならない。水源温度は必ずしも
一定というわけではなく、その日の外気温とか時
間帯によつて異なることもある。 To briefly explain the above FIG. 5, a pipe 40 from a water source is separated into a pipe 41 leading to a boiler 43 and a water heater 44 using solar heat.
A valve on the piping 40 is installed to open and close a valve depending on the increase or decrease in the water level in the water heater 44, close the valve when the water temperature exceeds a predetermined value, or drain the water inside the hot water pipe 44 as the outside temperature drops, and then Depending on the temperature of the water in the hot water pipe 44, it can be automatically determined whether the water to be used is from the hot water pipe 44 or used directly from the water source. It is designed to be selectively reheated and used as necessary, and to automatically drain water to prevent freezing. In the above case, since the thermostat TB1 is not provided in the flow path on the water source side, it cannot respond to temperature changes on the water source side. i.e. TH 1
is slightly higher than the water source temperature t 0 (t 0 +Δt=t 1 )
Since it is operated by t1, t1 must be placed in advance. The temperature of the water source is not necessarily constant, and may vary depending on the outside temperature of the day or the time of day.
仮に t0＝10℃ Δt＝５℃
t1＝15℃
に設定されていたとすると、TH1が15℃以下に
さらされたときにTH1は作動することとなる。
しかしながら、水源温度は変化するものであり、
温水管内の温度が16℃〜17℃、水源の温度が20℃
前後あつてもTH1は作動しない。よつて温水器
側の温度よりも水源側の温度の方が高くても、
TH1は作動せず、ボイラーへは低温側の流体が
供給されるために熱量の損失が大きい。これは、

る手段が設けられていないからに他ならない。 Assuming that t 0 = 10°C, Δt = 5°C, and t 1 = 15°C, TH 1 will be activated when TH 1 is exposed to a temperature below 15°C.
However, the water source temperature changes;
The temperature inside the hot water pipe is 16℃~17℃, the temperature of the water source is 20℃
TH 1 does not operate even if there is a difference between the front and back. Therefore, even if the temperature on the water source side is higher than the temperature on the water heater side,
TH 1 does not operate and low temperature fluid is supplied to the boiler, resulting in a large loss of heat. this is,
This is because there is no means for comparing the temperature of the fluid actually supplied to the boiler.

とする。 This idea solves the above problem, and when the hot water temperature on the solar collector side is below the set value, it is switched to the heater side, and the hot water temperature of this fluid is further compared with the tap water temperature, and the temperature is The purpose is to save thermal energy by switching the solenoid valve based on the difference and supplying high temperature fluid to the heater.

のである。 The basic structure of this device is to connect a collector using solar heat to a mixing faucet installed indoors through a direct flow path with a branch valve, and to adjust the temperature below the set value by selecting the temperature of the branch valve. The fluid is connected to the heater that receives the fluid by a branch flow path equipped with a solenoid valve and a temperature sensing element that switches the solenoid valve in response to the temperature of the fluid.
A water supply channel that connects directly to the water source and also has a temperature sensing element is connected to the electromagnetic valve, and the water temperatures sensed by both temperature sensing elements are compared to shut off the fluid on the low temperature side and heat the fluid on the high temperature side. The selection of the supply to the container is automatically made by a control circuit.

する。 Now, when the fluid introduced from the collector A shown in FIG. If the temperature is within or above the permissible setting value of the hot body 19, this fluid passes between the valve port 14a and the valve seat 15 and through the valve port 14 as shown in FIG. Hot water is continuously supplied to tap B. During this period, if the temperature of the fluid supplied from the collector A falls below the allowable value of the temperature sensing element 19, the working end 21 contracts and at the same time the springs 22 and 22a become unbalanced, causing the switching valve 17 to close to the valve seat 15. Press it against the valve port 14a.
is closed, and the valve port 14b and the outlet 11 are communicated with each other, so that the low-temperature fluid moves within the branch flow path 2 toward the solenoid valve 4 shown in FIG. Continue moving while making contact. In this case, when the sensitive value of the temperature sensitive element 6 is set to T 1 °C and the sensitive value of the temperature sensitive body 6a is set to T 2 °C, the temperature sensitive body 6
The resistance of the temperature sensing element 6a is R 1 and the resistance of the temperature sensing element 6a is R 2 , and the relationship maintains R 1 < R 2 , so the fluid is introduced into the heater 27 through the solenoid valve 4 which is open. ,
Heated to the appropriate temperature. Thereafter, as the temperature of the fluid flowing through the branch flow path 2 falls below the allowable value of the temperature sensor 6 and approaches the allowable value of the temperature sensor 6a due to a decrease in the outside temperature, the resistance of the temperature sensor 6 increases. When the resistance of the temperature sensor 6 becomes lower than the set value of the temperature sensor 6a, the resistance of the temperature sensor 6 becomes
R 1 ′, and the correspondence relationship is R 1 ′>R 2 , so the operational amplifier 9 operates, and one end of the relay 26 is grounded, current flows, and the relay 26 is turned on, so the internal contact of the relay 26 is closed. By connecting ON and C in Fig. 2 and turning on the solenoid valve, branch flow path 2 and 2a in Fig. 1 are shut off, and at the same time, branch flow path 2
A is switched to the water supply pipe 5, so tap water from the water supply pipe 5 is continuously supplied to the heater 27, and hot water at an appropriate temperature is supplied to the mixing faucet B via the hot water supply pipe 8.
Next, when the temperature of the fluid from the collector A rises due to the solar radiation being received by the collector A as the outside temperature rises, the operational amplifier 9 turns OFF when the resistance of the temperature sensor 6 becomes lower than the resistance of the temperature sensor 6a. solenoid valve 4
is turned off, the branch flow path 2 and the flow path 2a are connected to supply hot water to the heater 27, and when the water temperature further rises, the temperature sensing element 19 of the branch valve 3 is activated and the valve port 1 is turned off.
4a and close the valve port 14b at the same time. Therefore, the hot water temperature is directly supplied to the mixing faucet B via the direct flow path 1.
