口２から直接冷水が出ないようにしていた。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 hot water 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 Publication No. 15562), a cushion tank 5 with a heat-retaining heating element 4 installed therein is disposed in the middle of the piping 3 between the main hot water heat source 1 and the terminal hot water supply port 2, and the piping 3 The cold water and the hot water in the cushion tank 5 are mixed and flowed out from the hot water supply port 2, so that the cold water is not directly discharged from the hot water supply port 2.

の湯を使わないので、効率がよい。 In the figure, a hot water supply port 2 of a hot water supply circuit 6 is formed by connecting a main hot water heat source 1 and a hot water supply port 2 with a hot water supply pipe 3.
A terminal water heater 7 is installed in series near the terminal. The terminal water heater 7 has an electric heater 8, which is a heating device, installed inside the bottom of a hot water storage tank 9, and controls the heater input with a hot water temperature controller 11 according to the temperature detected by a hot water temperature thermometer 10. Maintains a specified high temperature. A water inlet 12 is provided at the lower end of this hot water storage tank 9, and a hot water outlet 13 is provided at the upper end. Near the water inlet 12, a three-way valve 15 is provided which is a switching valve for switching between the hot water supply pipe 3 and the water supply pipe 14 that supplies tap water. are installed in succession. That is, the three-way valve 15 selectively supplies hot water from the hot water supply pipe 3 or water from the water supply pipe 14 to the hot water storage tank 9. The hot water outlet 13 is connected to a check valve 16 of the hot water supply inlet 2 and a mixing faucet 17. On the other hand, water supply pipe 14
is connected to a water supply circuit 19 that supplies tap water from a water pipe 18 to the main hot water heat source 1 and the hot water supply port 2 . This water supply circuit 19 is connected to the check valve 20 of the hot water supply port 2 and the mixing faucet 17. FIG. 3 is a sectional view showing an embodiment of the three-way valve 15. Here, 2
Reference numeral 1 denotes a housing, and there is a passage for flowing from a hot water inlet 22 connected to the hot water supply pipe 3 to an outlet 23 connected to the hot water storage tank 9, and a passage for flowing from the water inlet 24 connected to the water supply pipe 14 to the outlet 23. A ball is used to switch between these two passages. Valve body 25 connects hot water inlet 22 and water inlet 24
and the exit 23. A valve shaft 26 is connected to the ball valve body 25, and the ball valve body 25 is rotated by an operation lever 27 to switch the passage. In the above configuration, if you want to use hot water continuously, operate the operating lever 27 to open the three-way valve 15.
The hot water supply pipe 3 and the hot water storage tank 9 are communicated with each other, and at the beginning of use, the hot water in the hot water tank 9 is supplied to the hot water supply port 2, and the cold water in the hot water supply pipe 3 works to push up the hot water in the hot water storage tank 9.
When hot water from the main water heater 1 eventually reaches the hot water storage tank 9, convection occurs due to the difference in specific gravity between the hot water and the water, raising the water temperature, allowing continuous hot water supply. On the other hand, when only a small amount of hot water is used, operate the operation lever 27 to open the water supply pipe 1.
4 and a hot water storage tank 9 are communicated, the hot water supply pipe 3 is closed, and hot water is supplied only with hot water in the hot water storage tank 9 without using the main hot water heat source 1. At this time, an arbitrary temperature can be selected by adjusting the valve of the mixing faucet 17.
In this way, if hot water is obtained immediately after starting hot water supply and only a small amount of hot water is used, it is unnecessary to use the main hot water heat source 1.
It is efficient because it does not use hot water.

済的である。Effects of the Invention As explained above, according to the water heater of the present invention, the terminal water heater is connected to the hot water circuit of the main water heater heat source device of central hot water supply, and the switching valve switches between hot water from the water heater heat source device and tap water. Since the water is selectively supplied to the terminal water heater, the time from opening the hot water tap at the hot water supply inlet until hot water comes out is extremely shortened, making it easy to use. In addition, when only a small amount of hot water is used, by operating the switching valve to supply tap water directly to the hot water storage tank of the terminal water heater, only the hot water from the terminal water heater is supplied, and the hot water from the main water heater is not used. Since it can be avoided, there is no unnecessary piping loss and it is economical.
