体内のほぼ全体の水温は上昇して行く。(1) When obtaining a large amount of hot water When the temperature of the water accumulated in the heat collector 16 rises due to solar heat, and a temperature difference between it and the water temperature at the bottom of the hot water storage can 7 opens, the circulation pump 18 is activated. Water in the lower part of the hot water storage can body 7 is conveyed to the heat collector 16 through the feed pipe 17. The hot water heated in the heat collector 16 passes through a return pipe 19, passes through a switching valve 20, and is supplied into the hot water storage can 7 from a substantially intermediate return pipe 22. In this case, the switching valve 20
The circuit of the upper return pipe 21 is closed by the operation of . In this way, the circulation pump 18 operates, and the heated hot water is passed from the substantially intermediate return pipe 22 to the hot water storage can body 7.
The water enters the inside and exchanges heat with the water in the hot water storage can body 7, raising almost the entire water temperature inside the can body.

体内上部の少量水の温度は上昇して行く。(2) When obtaining a small amount of relatively high-temperature hot water in a short time The water stored in the heat collector 16 is heated by solar heat, and if there is a temperature difference with the water temperature at the bottom of the hot water storage can 7, the water is circulated. The pump 18 is activated, and the water in the lower part of the hot water storage can 7 is conveyed to the heat collector 16 through the feed pipe 17. The hot water heated in the heat collector 16 passes through the return pipe 19, passes through the switching valve 20, and is supplied to the hot water storage can 7 from the upper return pipe 21. In this case, the circuit of the substantially intermediate return pipe 22 is closed by the operation of the switching valve 20. In this way, the circulation pump 18 operates, and the heated hot water enters the hot water storage can body 7 from the upper return pipe 21, and exchanges heat with the water in the upper part of the hot water storage can body 7. The temperature continues to rise.

時の温度調節が難しいという欠点があつた。 In this way, it was possible to obtain a large amount of hot water as needed, and it was also possible to obtain hot water at a relatively high temperature in a short period of time, so it was valuable in terms of ease of use. However, if there is no action of solar heat and heat collection is not performed, or if heat collection is insufficient, the water in the hot water storage can 7 cannot be heated, and the temperature inside the hot water storage can 7 will not rise, especially in winter. It was a small amount. Next, when obtaining a small amount of high-temperature hot water, there is a vertical temperature distribution in the high-temperature water above the area near the upper return pipe 21, so the amount of hot water is not uniform when hot water is dispensed, and in practical terms, it is difficult to adjust the temperature, especially during showering. There were flaws.

ることができる。 In the above configuration, (1) When obtaining a large amount of hot water First, a combustion flame is formed in the burner 1 and heats the fin type heat exchanger. Now, the water in the hot water storage can 7 enters the heat exchanger 2 through the water supply port 8, where it is exchanged with combustion heat and its temperature rises. The heated water has a lower specific gravity and enters the hot water storage can through the hot water supply port 9 and moves to the upper part of the hot water storage can 7 due to draft action. Furthermore, heat exchange with surrounding water is performed, and the temperature of the hot water stored in the hot water storage can body 7 rises uniformly over almost the entire area. Next, the temperature of the hot water in the hot water storage can 7 rises, and when it reaches a set temperature (for example, 80° C.), the temperature detector 14 is activated and the burner 1 can be turned off. If solar heat collection is not sufficient, a large amount of hot water can be obtained by operating the heater as described above.

ぼ全域に渡つて均一に温度が上昇する。 Next, a case where solar heat is collected will be explained. When the temperature of the water stored in the heat collector 16 rises due to solar heat and there is a temperature difference between it and the water temperature at the bottom of the hot water storage can 7 (detected by the temperature detector 23), the circulation pump 18 is activated. Water in the lower part of the hot water storage can body 7 is conveyed to the heat collector 16 through the feed pipe 17. The hot water heated in the heat collector 16 passes through a return pipe 19, passes through a switching valve 20, and is supplied into the hot water storage can 7 from a substantially intermediate return pipe 22. In this case, the circuit of the upper return pipe 21 is closed by the operation of the switching valve 20. In this way, the circulation pump 18 operates, and the heated hot water enters the hot water storage can body 7 from the substantially intermediate return pipe 22 and exchanges heat with the water in the hot water storage can body 7, thereby almost covering the entire area inside the hot water storage can body 7. The temperature rises uniformly over the period.
このように太陽熱の集熱がある場合はもちろん

略図である。(2) When obtaining a small amount of high-temperature hot water in a short time The high-temperature hot water obtained in the heat exchanger 2 and passed through the hot water supply pipe 10 by the operation of the switching valve 11 is transferred to the hot water outlet pipe 10A in the hot water storage can body 7. Hot water is discharged from the plurality of small holes 10B into the water above the hot water storage can body 7, and heat is exchanged with each other. Multiple small holes 1
The hot water, whose temperature has increased due to heat exchange near 0 B , moves to the upper part of the hot water storage can 7, and in the process of moving, it also exchanges heat with surrounding water. FIG. 2 is a sectional view taken along line E-L in FIG. 1, and FIG. 3 is a schematic diagram of the tapping pipe 10A .
さて本発明の一実施例においては出湯パイプ１

ができる。 Now, in one embodiment of the present invention, the hot water outlet pipe 1
Since the plurality of small holes 10 B provided in 0 A are arranged toward the circumferential direction of the hot water storage can body 7, the small holes 1
The heat transfer of the high - temperature hot water spouted from the outlet pipe 10A to the lower part of the can body is relatively small, and the high-temperature hot water that is spouted from the hot water outlet pipe 10A is divided into finely divided high-temperature hot water and water (35 to 40) in the upper part of the hot water storage can body 7. Because heat is exchanged uniformly, a stable amount of hot water with a relatively high and uniform hot water temperature can be obtained.

It is conveyed to the heat collector 16 through the pipe 17. The hot water heated in the heat collector 16 passes through the return pipe 19, passes through the switching valve 20, and is supplied to the hot water storage can 7 from the upper return pipe 21. In this case, the circuit of the substantially intermediate return pipe 22 is closed by the operation of the switching valve 20.
