1 is connected. The auxiliary tank 11 has a pipe shape having approximately the same height as the hot water storage tank 1, and is arranged in parallel with the hot water storage tank 1.

Both tanks are in communication with each other. Each communication pipe 12-1
The position of the foil tube No. 5 is as follows. That is, the hot water storage tank 1 is divided into approximately five equal parts in the height direction, and from the top to the bottom, the first communicating pipe 12 is in the first stage, the second communicating pipe 13 is in the second stage, and the third stage is divided into five equal parts. A third communication pipe 14 is arranged at the fifth stage, and a fourth communication pipe 15 is arranged at the fifth stage.

し、補助槽11内で湯水の温度成層が形成される
ことになる。 In the hot water storage device described above, hot water taken from the hot water storage tank 1 into the circulation circuit 5 by the operation of the circulation pump 4 is heated (temperature raised) by the heating source 6 and flows to the auxiliary tank 11 . The hot water flowing into the auxiliary tank 11 is
The water is divided into communication pipes 12 to 15 due to the difference in specific gravity.
In other words, the lower the temperature of hot water, the greater its specific gravity;
As the temperature increases, the specific gravity decreases, so hot water with low specific gravity (i.e. hot water) flows upward, and hot water with high specific gravity (i.e. low temperature hot water) flows downward. The water flows, and temperature stratification is formed in the hot water within the auxiliary tank 11.
このため、第2図に示すように、循環回路5か

連通管15を通して貯湯槽1内へ流れる(図中、
矢印D参照)。 Therefore, as shown in FIG. 2, the hot water HW flowing from the circulation circuit 5 to the auxiliary tank 11 flows to the hot water storage tank 1 through each of the communication pipes 12 to 15 according to its temperature. That is, if the hot water HW flowing from the circulation circuit 5 to the auxiliary tank 11 is slightly higher than the temperature of the existing hot water in the auxiliary tank 11, it flows into the hot water storage tank 1 through the second communication pipe 13 (Fig. Middle, arrow B
), and if the temperature is higher than that, the first
The water flows into the hot water storage tank 1 through the communication pipe 12 (in the figure,
(see arrow A), and if the temperature is slightly lower than the existing hot water temperature in the auxiliary tank 11, the hot water flows into the hot water storage tank 1 through the third communication pipe 14 (see arrow C in the figure), If the temperature is lower, the hot water flows into the storage tank 1 through the fourth communication pipe 15 (in the figure,
(See arrow D).
従つて貯湯槽1内には、補助槽11から各連通
管12〜15を通つて流れてくる湯水によつて、
次第に温度差による温度成層が形成され、貯湯槽
1の上部から下方へ順に高温層から低温層に至る
各層が短時間で形成される。 Therefore, hot water flowing from the auxiliary tank 11 through the communication pipes 12 to 15 into the hot water storage tank 1 causes
Temperature stratification is gradually formed due to the temperature difference, and each layer from the high temperature layer to the low temperature layer is formed in order from the top to the bottom of the hot water storage tank 1 in a short time.
この結果、循環回路5から補助槽11に流れて
きた湯水HWの温度が既存の湯水の温度よりも高

ら出湯される。 As a result, if the temperature of the hot water HW flowing from the circulation circuit 5 to the auxiliary tank 11 is higher than the temperature of the existing hot water, it is passed through the first communication pipe 12 and the second communication pipe 13 to the hot water storage tank 1. Since the water flows to the inner upper part (see arrows A and B in the figure), high-temperature hot water is generated in the upper part of the hot water storage tank 1 in a short time. Note that the high-temperature hot water is discharged from the hot water outlet 3 by hot water supply on the downstream side of the hot water outlet 3.
また循環回路5から補助槽11に流れてきた湯

の湯水の温度が安定化される。 Further, when the temperature of the hot water HW flowing from the circulation circuit 5 to the auxiliary tank 11 is lower than the temperature of the existing hot water, it flows to the lower part of the hot water storage tank 1 through the third communication pipe 14 and the fourth communication pipe 15. (In the figure, arrow C,
(see D), the hot water HW does not mix with the high-temperature hot water in the upper part of the hot water storage tank 1, and the temperature of the high-temperature hot water is stabilized.

湯水の高温状態を保持することができる。 Further, when the temperature of the hot water HW flowing from the circulation circuit 5 to the auxiliary tank 11 is lower than the temperature of the existing hot water, the hot water HW passes through the third communication pipe 14 and the fourth communication pipe 15 to the lower part of the hot water storage tank 1. (in the figure,
(see arrows C and D), when convection occurs between the auxiliary tank 11 and the hot water in the hot water storage tank 1, the hot water in the hot water storage tank 1 flows to the auxiliary tank 11 through the second communication pipe 13. (See arrow E in FIG. 3) Therefore, the flow of high temperature hot water in the upper part of the hot water storage tank 1 is prevented, and the high temperature state of the hot water can be maintained.

可能である。 In addition, in this example, each intake port 8, 9 from the hot water storage tank 1
The temperature-adjustable three-way valve 7 is operated depending on the temperature of the hot water introduced into the circulation circuit 5. That is, when the hot water flowing through the three-way valve 7 is below a predetermined temperature, the upper intake port 8 is opened and the lower intake port 9 is closed, and the hot water in the upper part of the hot water storage tank 1 is allowed to flow into the circulation circuit 5. When the hot water in the upper part of the hot water storage tank 1 is heated in a short time by the heating source 6, and the hot water flowing through the three-way valve 7 is at a predetermined temperature or higher, the upper intake port 8 is closed and the lower intake port 9 is opened. Then, the circulation of the high temperature hot water in the upper part of the hot water storage tank 1 is stopped, and the low temperature hot water is circulated and heated by the heating source 6. Therefore, the temperature-adjustable three-way valve 7 actively generates high-temperature hot water in the upper part of the hot water tank 1, and also prevents wasteful circulation of high-temperature hot water, thereby preventing high-temperature hot water from entering the hot water tank 1. It is possible to generate it reasonably.

5 can be set to an appropriate number, and the arrangement positions of the communication pipes and the return port 10 can also be set as appropriate. For example, the third communication pipe 14 of the embodiment may be eliminated as shown in FIG. 4, and the return port 10 and the second communication pipe 13 may be arranged substantially horizontally.

That is, the return port 10 of the circulation circuit 5 is communicated with the second auxiliary tank 17, and the second auxiliary tank 1
The upper side communication port 18 of 7 is connected to the auxiliary tank 11, and the lower side communication port 19 is connected to the auxiliary tank 11. Note that the upper communication port 18 is connected to the auxiliary tank 11 at a position that is almost horizontal between the first communication pipe 12 and the second communication pipe 13, and the lower communication port 19 is connected to the third communication pipe 13. It is connected to the auxiliary tank 11 at a position substantially horizontal to the upper position between the pipe 14 and the fourth communication pipe 15. According to this, the auxiliary tank 11 and the second auxiliary tank 17 generate two-step temperature stratification in the hot water flowing from the circulation circuit 5. It is possible to produce even better results.

The low-temperature hot water flows to the top of the hot water storage tank through the lower communication pipe, and temperature stratification is generated in the hot water in the hot water storage tank. The location where the hot water flows into the hot water storage tank is selected depending on the temperature of the hot water flowing through the circulation circuit, and if the hot water flowing through the circulation circuit is at a low temperature, mixing with the high temperature hot water in the upper part of the hot water storage tank is avoided, and the hot water is stored. This has the effect of keeping the hot water in the upper part of the tank at a high temperature without causing a drop in temperature.
