うにしていた。Conventional technology Central hot water supply is commonly used because it has the effect of concentrating the heat source when hot water is supplied to multiple outlets. At the beginning of use, it is inconvenient in actual use that not only does the cold water in the pipes come out, but it also takes time for hot water at a predetermined temperature to come out. As a means to eliminate such inconveniences and inconveniences, for example, Fig.
As shown in Japanese Patent No. 15562), a cushion tank 5 with a heat-retaining heating element 4 inside is installed in the middle of the piping 3 between the main hot water heat source 1 and the hot water outlet 2 of the terminal. The cold water and the hot water in the cushion tank 5 are mixed and flowed out from the tap 2, so that the cold water is not directly discharged from the tap 2.

大きくする必要があった。Problems to be Solved by the Invention However, in the conventional configuration described above, the main hot water heat source 1 and the cushion tank 5 are directly connected through the pipe 3, and all of the cold water in the pipe 3 and the hot water in the cushion tank 5 are mixed. Because the hot water was being drained out, hot water comes out immediately at the beginning of use, but in order to prevent the temperature of the hot water from the hot water supply port 2 from falling below the lower limit of the hot water supply temperature (generally 30'C to 40°C). , the capacity of the cushion tank 5 had to be larger than the capacity of the water in the pipe 3.
そのため、設置スペースや重量が大きくなるばかりでな
く、クッションタンクからの放熱損失も多くなってしま
うという欠点を有していた。Therefore, not only the installation space and weight become large, but also the heat radiation loss from the cushion tank increases.

When the temperature of the vessel drops, the on-off valve of the second flow path is opened, and the cold water in the first flow path is divided into two into the sub-hot water heat source and the second flow path, and a portion of the cold water is sent to the sub-hot water supply. Allow it to flow to the heat source. Therefore, the amount of hot water that can be stored in the auxiliary hot water heat source device can be reduced by the amount of cold water flowing out from the second flow path. Eventually, the hot water from the main water heater reaches the auxiliary water heater, and when the temperature of the auxiliary hot water heater rises, the on-off valve is closed, and all the hot water from the main water heater flows to the outlet, allowing continuous hot water supply. It becomes possible.

に2分している。In the figure, a main hot water heat source 1 and a hot water outlet 2 are connected by a hot water supply pipe 6, which is a first flow path, and a sub hot water heat source 7 is connected to the hot water supply pipe 6 near the hot water outlet 2. The auxiliary hot water heat source device 7 has an electric heater 8 internally installed at the bottom of the hot water storage tank 9, and maintains a predetermined high temperature by controlling the heater input with a hot water temperature controller 11 according to the temperature detected by a hot water temperature thermometer 10. are doing. At the lower end of this hot water storage tank 9 is an inlet pipe 12. An outlet pipe 13 is provided at the upper end, and the inlet pipe 12 and outlet pipe 13 are connected in parallel to the hot water storage tank 9 via a bypass pipe 14. Upstream of the auxiliary hot water heat source device 7 of the hot water supply piping 6, a branch portion 16 to the auxiliary hot water outlet pipe 15, which is a second flow path, is installed to connect the flow from the main hot water heat source device 1 to the auxiliary hot water heat source device 7 side. It is divided into two parts on the hot water outlet pipe 15 side.

2に水道水を供給するよう接続されている。An on-off valve 17 for opening and closing the auxiliary hot water tap pipe 15 is provided on the side of the auxiliary hot water tap pipe 15 of the branch portion 16. The on-off valve 17 includes a solenoid valve 18 inserted into the auxiliary hot water tap 15, a temperature sensor 19 that detects the water temperature at the bottom of the hot water tank 9, and a temperature sensor 19.
Controller 2 that controls the opening and closing of the solenoid valve 18 based on the signal of
0, the solenoid valve 18 is controlled to close when the temperature detected by the temperature sensor 19 exceeds a preset temperature, and to open the solenoid valve 18 when the temperature detected by the temperature sensor 19 falls below the set temperature. Ru. The hot water outlet 2 is a hot water flow control valve 2.
1 and the outlet of the water flow control valve 22 are connected by a secondary mixing section 23, so that the mixed hot water flows out. This hot water flow control valve 21 is connected to a primary mixing section 24 which is a confluence point of the outlet pipe 13 and the bypass pipe 14 . On the other hand, the water supply pipe 25 connects the main hot water heat source 1 and the water flow control valve 2 from the water pipe 26.
2 is connected to supply tap water.

If the detected temperature of the hot water tank 9 is lower than the set temperature of the on-off valve 17, the solenoid valve 18 is opened, and one side of the flowing cold water from the hot water supply pipe 6 works to push up the hot water in the hot water storage tank 9, and also to push up the hot water in the bypass pipe 14. The water flows to the primary mixing section 24 where it mixes with the high temperature hot water in the hot water storage tank 9, and flows to the secondary mixing section 23 at an appropriate temperature.

れているため、電磁弁18は閉の状態が維持され、補助
出湯管16からの無駄な出湯は無い。The other side of the cold water in the hot water supply pipe 6 flows to the auxiliary hot water outlet pipe 15. When hot water from the main water heater 1 eventually reaches the hot water storage tank 9, the temperature detected by the temperature sensor 19 rises to exceed the set temperature of the on-off valve 17, and the solenoid valve 18 closes. Therefore, all the hot water flowing through the hot water supply pipe 6 passes through the auxiliary hot water heat source 7 and flows out from the hot water outlet 2. On the other hand, in the auxiliary hot water heat source 7, the cold water that has accumulated in the hot water storage tank 9 begins to flow out, but the bypass pipe 1
Since the hot water from the main water heater 1 flows into the main water heater 4, the temperature of the hot water in the primary mixing section 24 hardly decreases, and continuous hot water supply is possible. After the hot water supply is stopped, the hot water storage tank 9 is always kept at a high temperature, so the electromagnetic valve 18 remains closed, and no hot water is wasted from the auxiliary hot water pipe 16.
上記のように、補助出湯管15より流出する水量は副給
湯熱源器7へ流れないため、その分貯湯槽9の容量が小
さくしても、副給湯熱源器7の湯切れはない。したがっ
て、貯湯槽9の容量を小さくすることができ、副給湯熱
源器7の設置スペース及び重量は小さくなる。As described above, the amount of water flowing out from the auxiliary hot water supply pipe 15 does not flow to the auxiliary hot water heat source device 7, so even if the capacity of the hot water storage tank 9 is reduced accordingly, the auxiliary hot water heat source device 7 will not run out of hot water. Therefore, the capacity of the hot water storage tank 9 can be reduced, and the installation space and weight of the auxiliary hot water heat source 7 can be reduced.
また、貯湯槽9に並列にバイパス管14を設けているた
め、貯湯槽9に流入する水量は2分され、なお貯湯槽9
容量は小さくできる。In addition, since the bypass pipe 14 is provided in parallel with the hot water storage tank 9, the amount of water flowing into the hot water storage tank 9 is divided into two, and the amount of water flowing into the hot water storage tank 9 is divided into two.
Capacity can be reduced.
さらに、給湯開始直後より湯が得られるため、使い勝手
が良くなるばかりでなく、補助出湯管15からの水も同
時に活用できるため効率がよい。Furthermore, since hot water can be obtained immediately after hot water supply starts, it is not only convenient to use, but also efficient because water from the auxiliary hot water pipe 15 can be used at the same time.
実施例での主給湯熱源器は限定しなかったが、ガス瞬間
湯沸器であれば、点火水量を超えなければ着火しないた
め、僅かの水量では給湯できない場合があった。これを
、本発明によれば、第2の流路の水量を点火水量より大
きな値に設定しておけば、出湯口で低水量の給湯を行っ
てもガス瞬間湯沸器は安定した着火が可能である。Although the main hot water heat source device in the embodiment was not limited, if it was a gas instantaneous water heater, it would not ignite unless the amount of water exceeded the ignition water amount, so hot water could not be supplied with a small amount of water in some cases. According to the present invention, if the water volume in the second flow path is set to a value larger than the ignition water volume, the gas instantaneous water heater can be stably ignited even when a low water volume is supplied at the outlet. It is possible.
