給湯使用温度の下限(30〜40℃)を下回らない
ようにする必要があるため、クツシヨンタンク
5の容量は配管3内の水の容量より大きくする
必要がある。(2) Even if the cold water in the pipe 3 mixes in the cushion tank 5, the temperature in the cushion tank 5 must not fall below the lower limit of the hot water supply temperature (30 to 40 degrees Celsius). Therefore, the capacity of the cushion tank 5 needs to be larger than the capacity of the water in the pipe 3.
(3) 使い始めはクツシヨンタンク5内の高温の湯

一部材には同一番号を付している。 In FIG. 1, reference numeral 6 denotes an instant hot water supply device, which is connected so that hot water from the main hot water supply heat source 1 flows through a hot water supply piping 3 and is supplied to the instant hot water supply device 6, and water is supplied from a water supply piping 7. The instant hot water supply device 6 is connected to the connection port A8.

A bypass section 1 in which an upstream branch pipe 15 and a downstream branch pipe 16 are arranged in parallel upstream of the hot water temperature regulating constriction section 13 of the hot water side flow path 9.
7, a hot water storage tank 21 having an inlet pipe 18, an outlet pipe 19, and a heating device 20 which is an electric heater, and a connecting pipe 22 that connects the upstream branch pipe 15 and the inlet pipe 18 and the downstream branch pipe 16 and the outlet pipe 19. It consists of. The hot water temperature adjusting throttle section 13 includes a throttle valve A23 that controls the amount of water flowing through the hot water side flow path 9, a throttle valve B24 that controls the amount of water flowing through the water side flow path 10, and a thermos that detects the mixed hot water temperature of the faucet section 12. If the detected value of the thermostat 24 is higher than a predetermined value, the throttle valve A2 is
3, the throttle valve B24 is opened, and if the detected value is low, the throttle valves A23 and B24 are operated in the opposite manner to control the mixed water temperature to a predetermined value. Bypass section 17
The upstream branch pipe 15, the connecting pipe 22, the hot water storage tank 21,
In order to make the overall flow path resistance of the downstream branch pipe 16 and the flow path resistance between the upstream branch pipe 15 and the downstream branch pipe 16 of the hot water side flow path 9 approximately the same, an orifice 2 is installed in the hot water side flow path 9.
6 is installed internally. In the hot water storage tank 21, the inlet pipe 18 is inserted to the bottom of the hot water storage tank 27, and the outlet pipe 19 is provided on the top surface of the hot water storage tank, so that the high temperature hot water in the hot water storage tank is pushed up from the bottom by water injected from the inlet pipe 18. and is pushed out from the outlet pipe 19. Further, the heating device 20 is installed inside the bottom of the hot water storage tank 27, and maintains a predetermined high temperature by controlling the heater input with a hot water temperature controller (not shown).

高温の湯はやがて無くなるが、今度は主給湯熱源
1からの高温湯が湯側流路9に流入し、下流分岐
管16の下流では適当な混合湯が作られる。 In the above configuration, when the hot water amount adjustment valve 14 is opened, the cold water in the hot water supply pipe 3 flows into the hot water side flow path 9,
The upstream branch pipe 15 divides the flow into two directions. One of the hot water flows directly through the orifice 26 of the hot water side flow path 9 to the contact point of the downstream branch pipe 16, and the other flows through the upstream branch pipe 15, the connecting pipe 22, and the inlet pipe 18 to the lower part of the hot water storage tank 27. Inside the hot water storage tank 27 is a heating device 2.
It is filled with hot water that has risen to a high temperature due to 0.
The cold water flowing in from the inlet pipe 18 pushes up the high-temperature water due to the difference in specific gravity between the hot water and the hot water and is forced out from the outlet pipe 19. This hot water flows into the hot water side flow path 9 via the connecting pipe 22 and the downstream branch pipe 16, where it merges with the flow of the hot water side flow path 9 to create mixed hot water. The flow ratio of this mixed hot water and the water flowing through the water side channel 11 is adjusted by the throttle valve A23 and the throttle valve B24 of the hot water temperature adjusting throttle section 13, respectively, and the water is mixed at a predetermined temperature from the faucet section 12. Hot water is provided. The high-temperature hot water in the hot water storage tank 21 will eventually disappear, but the high-temperature hot water from the main hot water supply heat source 1 will now flow into the hot water side flow path 9, and a suitable mixed hot water will be created downstream of the downstream branch pipe 16.
以上の構成・作用により、最初から所定の湯を

有利であるなどの効果がある。 With the above configuration and operation, it is possible to stably supply a predetermined amount of hot water from the beginning.Moreover, since the flow of the hot water side flow path 9 and the hot water storage tank 21 are divided into two, the capacity of the hot water storage tank 21 is Since only 1/2 of the piping 3 is required, the installation space can be reduced and the capacity of the heating device can be reduced compared to the conventional example, which requires more than the capacity of the hot water supply piping 3. Furthermore, the surface area of the hot water storage tank is small and the amount of heat dissipated is reduced. Also, the connecting pipe 22
Since the faucet part 14 and the hot water tank 21 can be separated from each other, the hot water tank 21 can be installed in a place where it cannot be seen, such as under a kitchen sink, which is advantageous in terms of aesthetics and installation.

由度が上がる。 In the embodiments described above, the hot water volume adjustment valve 14 is provided on the downstream side of the hot water storage tank 21, which is a first stop type configuration, but the present invention also provides a first stop type configuration in which the hot water volume adjustment valve is located on the upstream side of the hot water storage tank 21. A similar effect can be obtained. Moreover, in this case, the hot water storage tank 27 can have a non-pressure-resistant structure, which increases the degree of freedom in terms of shape.
