7 is a pump interposed in the circulation circuit, and 8 is a three-way valve provided at the pump suction port. 9 is a three-way valve 8
A hopper connected to one opening of the bath is used to separate the hot water supply circuit and connect it to the bath circulation circuit. In the hot water supply circuit, the hot water supply pipe 10 from the hot water heat exchanger 2 is branched, one side is used as a general hot water supply pipe 11 connected to a kitchen, etc., and the other side is connected to the hopper 9.
A bath water supply pipe 12 is connected to the bath water supply pipe 12. Reference numeral 13 denotes a flow path priority valve provided at a branch part of the hot water supply circuit, and a valve body 1 opens and closes passages to both hot water supply pipes 11 and 12 in conjunction with each other.
It has 9,20. It should be noted that valve body 19 has a larger pressure receiving area, and priority is given to the general hot water supply side. 14
is a temperature-sensitive switching valve interposed in a bypass passage 15 that connects the discharge side of the pump 7 of the bath circulation circuit and the return pipe 6 upstream of the three-way valve 8. The temperature-sensitive switching valve 14 includes a valve body 16 that opens and closes the bypass passage 15, and an outgoing pipe 5.
It is formed of a shape memory alloy spring 17 located inside and expanded by hot water to bias the valve body 16, and a bias spring 18 biasing in the opposite direction to the shape memory alloy spring 17.

る。 Next, the operation of the above configuration will be explained.
During general hot water supply, when the collar is opened, the pressure inside the hot water supply pipe 11 decreases and the valve body 19 opens to discharge hot water. When hot water is supplied to the bath at the same time, when a solenoid valve (not shown) provided in the bath hot water supply pipe 12 is opened, the pressure inside the hot water supply pipe 12 is reduced, and the valve body 20 is opened. However, since the valve body 19 has a larger pressure receiving area, more water flows toward the hot water supply pipe 11 side. In other words, priority is given to general hot water supply. When the use of the general hot water supply ends, the pressure inside the general hot water supply pipe 11 becomes equal to the pressure inside the hot water outlet pipe 10, and all the water flows to the hot water supply pipe 12 side. The hot water flowing into the bath water supply pipe 12 is brought to the boiling temperature of a bath by a water heater. The hot water accumulated in the hopper 9 is guided to the suction side of the pump 7 by the three-way valve 8, and is forced into the bathtub 4 by the discharge force of the pump 7. At this time, the shape memory alloy spring 17 disposed in the outgoing pipe 5 is contracted, and the bias spring 18 causes the valve body 16 to open the bypass passage 15. Therefore, the poured hot water is conveyed to the bathtub 4 through both the outgoing pipe 5 and the return pipe 6. When the bathtub water level reaches the set water level, a water level detector (not shown) outputs a dropping operation end signal, and the dropping operation is completed. After this, circulating heating is performed until the temperature of the water in the bathtub reaches the set temperature. Set the three-way valve 8 to the circulation side and operate the pump 7. Then, the hot water heated by the heat exchanger 3 flows through the outgoing pipe 5. The temperature of the water at this time is high because it further heats the water that has been poured into it. The shape memory alloy spring 16 is expanded by the hot water and closes the bypass passage 15 with the valve body 16. This forms a circulation circuit between the pump 7 and the bathtub 4.
（考案の効果）
以上のように本考案は、バイパス弁を往管内の
湯温によつて自動的に開閉する感温弁としたの
で、弁開閉のための制御回路やコード等が不要と
なり、弁自体もコンパクトとなると共に安価にな
る。(Effects of the invention) As described above, in the present invention, the bypass valve is a temperature-sensitive valve that automatically opens and closes depending on the water temperature in the outgoing pipe, so there is no need for a control circuit or code for opening and closing the valve. The valve itself is also more compact and less expensive.
尚、実施例の如く出湯管の分岐部に流路優先弁
を設けると、一般給湯使用時に自動落し込みが始
まつても一般給湯側の湯量が激減することはなく
使い勝手が良くなる。 In addition, if a flow path priority valve is provided at the branch part of the hot water outlet pipe as in the embodiment, even if automatic dropping starts during use of general hot water supply, the amount of hot water on the general hot water supply side will not be drastically reduced, improving usability.
