操作によって行なわれる。The heat medium heated in the heat collector 1 is returned to the hot water supply tank 2 provided below by the heat collection pump 3 through the heat collection return pipe 4, which is a heat collection pipe, and is returned to the hot water supply tank 2 provided below. A hot water supply heat exchanger 5 provided in the hot water supply tank 2 exchanges heat with the water in the hot water supply tank 2. The heat medium that has completed heat exchange with the water in the hot water supply tank 2 passes through a heat collection feed pipe 6, which is also a heat collection pipe, and returns to the heat collector 1 again, forming a circulation circuit. The heat collecting pump 23 is provided in the heat collecting and sending pipe 6. Further, a bathtub 7 is installed below the heat collector 1 in parallel with the hot water supply tank 2, and the bathtub 7 is provided with a heat exchanger 8 for exchanging heat with the water in the bathtub 7. 9 is the heat collection return pipe 4
This bypass pipe 9 is a bypass pipe provided by branching from
is connected to the heat exchanger 8, and is also connected to the heat collecting and sending pipe 6 via an electric three-way valve 1o which is a route switching valve. Further, the electric three-way valve 1o receives an operation command via the control device 12 by selection with the operation switch 11, and is operated on the heat collection pipe side, that is, the hot water supply tank 2 side, or the bypass pipe 9 side, that is, the bathtub 7 side. Choose one of the routes. In this case, the ) Kuinokusu pipe 9 is provided by branching from the heat collection return pipe 4 before entering the hot water supply tank 2, and after passing through the heat exchanger 8, the hot water enters the hot water supply tank 2. It is connected to the heat collecting and sending pipe 6 after exiting the hot water supply tank 2.
and bathtub 7 are located in parallel along the heat collection path. Therefore, the heat medium that has completed heat exchange in the heat exchanger 8 of the bathtub 7 passes through the hot water heat exchanger 6 in the hot water supply tank 2, and then passes through the hot water supply heat exchanger 6 in the hot water supply tank 2
There is no inconvenience such as cooling the hot water that has already stored heat inside. In addition, the nokuinosu pipe 9 further has a branched communication pipe 13, and an electric three-way valve 1 which is a route switching valve.
It is connected to the heat collecting and sending pipe e through 4. This electric three-way valve 14 is connected to the heat collecting and feeding pipe 6 side or to the connecting pipe 1.
By selecting the third side, switching between heat collection operation and waste heat recovery operation is performed. This selection is made by operating the operation switch 11.

停止する。Operate the switch 11 to first select bathtub priority heat collection. As a result, the electric three-way valve 10 is switched to select the bypass pipe 9 side, forming a circuit as shown in FIG. 2. When the temperature of the heat collector 1 rises due to sunlight and the temperature difference between the heat collector 1 and the bathtub 7 increases, the high temperature side sensor 16 and the bathtub 7
The heat collection pump 3 is operated via the control device 12 in cooperation with the low temperature side sensor 17 . And the heat medium is heat exchanger 1
8, the temperature of the water in the bathtub 7 rises and becomes hot water. When the water temperature in the bathtub 7 rises above a predetermined value, the electric three-way valve 10 is automatically switched to collect heat to the hot water supply tank 2 side as shown in FIG. Further, when the temperature difference between the heat collector 1 and the hot water supply tank 2 becomes equal to or less than a set value, the operation of the heat collection pump 3 is stopped.

In this case, heat collection is performed only by the circuit shown in FIG. In the heat collection mode shown in FIGS. 2 and 3, the electric three-way valve 14 is switched to the side that closes the connecting pipe 13, but the hot Japanese Patent Application Publication No. 58-80431 that has been used in the bathtub 7 is (3) When water remains and there is a waste heat recovery operation in which heat is recovered to the hot water storage tank 2 side, the electric three-way valve 14 is switched to open the connecting pipe 13 side as shown in Fig. 4. . When the heat collection pump 3 is operated, the waste heat from the bathtub 7 is recovered into the hot water supply tank 2, and when the temperature difference between both 2 and 7 becomes less than the set value, the heat collection pump 3 is automatically activated. Stop driving.

The inconvenience that the heat medium, whose temperature has become lower after completing the heat exchange, absorbs heat from the hot water with a higher temperature in the hot water supply tank 2 and lowers the temperature of the hot water supply tank 2, is eliminated. In addition, since the bypass pipe 9 further branches and has a communication pipe 13 connected to the heat collecting pipe via an electric three-way valve 14, the bathtub 7
It becomes possible to take the waste heat into the hot water supply tank 2.

々のすぐれた効果を有するものである。As described above, the solar water heater of the present invention is provided with a bathtub in addition to the hot water storage tank, and a heat exchanger that exchanges heat with the water in the bathtub. Since it can be switched by a path switching valve, it has the following various excellent effects.
（１）浴槽用の温水は、浴槽に水を張った状態で太陽熱
集熱ができるだめ、給湯貯湯槽の容量は浴槽の容量を差
し引いた容量で済み、その結果、給湯貯湯槽を小型で、
かつコンパクト托することができるとともに、設置スペ
ースも削減できる。(1) Hot water for bathtubs can collect solar heat while the bathtub is filled with water, so the capacity of the hot water storage tank is just the capacity of the bathtub.As a result, the hot water storage tank can be made smaller,
Moreover, it can be made compact and the installation space can be reduced.
（２）給湯貯湯槽と浴槽への集熱運転が切換られ、かつ
給湯貯湯槽および浴槽とも従来方式のものよシ小さくで
きるため、その集熱も高い温度まで早く昇温させること
かできる。(2) Since the heat collection operation to the hot water supply tank and the bathtub is switched, and both the hot water supply tank and the bathtub can be made smaller than those of the conventional system, the heat collection can also be quickly raised to a high temperature.
（３）入浴をしない日には、給湯貯湯槽への集熱のみで
済むため、蛇口からの給湯使用量に見合った湯量が高温
で得られることになシ、その結果、湯量が大量に余った
９、給湯貯湯槽内の温度が風呂を使わない日でも低いと
いう不満はなくなる。(3) On days when you do not take a bath, heat only needs to be collected in the hot water storage tank, so the amount of hot water commensurate with the amount of hot water used from the faucet cannot be obtained at a high temperature, and as a result, a large amount of hot water is left over. 9. There will be no more complaints about the temperature in the hot water storage tank being low even on days when the bath is not used.
（４）経路切換弁でバイパス管側を選択することにより
