縮するには至らなかつた。 BACKGROUND ART Conventionally, a hot water storage tank having a coil-type heat exchanger has been used in an indirect heating type solar water heater. However, because it is disadvantageous in terms of manufacturing, etc.
We proposed the jacket type shown in Figure 1. In the figure, 1 is a hot water storage tank, and a hot water storage tank main body 2,
It consists of a heat exchange jacket 3 provided on its outer periphery. The heat exchange jacket 3 has a heat medium inlet 4 at the top, a heat medium outlet 5 at the bottom, and a circulation pipe 7 connected to the heat collector 6.
They are connected via a and 7b. 8 is the pump,
9 is an expansion tank. Compared to conventional coil-type heat exchangers, such a jacket-type heat exchanger has a more uniform temperature distribution within the hot water storage tank body 2, and can easily supply high-temperature hot water more quickly. However, even in this case, the time required to obtain the hot water temperature required for hot water supply has not been sufficiently shortened.

４，２５が設けられている。 An embodiment of this invention is shown in FIGS. 2 to 4. In the figure, reference numeral 10 denotes a hot water storage tank main body formed in the shape of a rice bag, and a heat exchange jacket 11 that forms a heat medium chamber between the outer periphery and the outer surface of the hot water storage tank main body 10.
is provided. The heat exchange jacket 11 is divided into an upper split jacket 12 and a lower split jacket 13. The upper split jacket 12 is provided with a heating medium inlet 14 at its upper end and a heating medium outlet 1 at its lower end.
5 is provided. The lower split jacket 13 is provided with a heating medium inlet 16 at its upper end and a heating medium outlet 17 at its lower end. Both heat medium inlets 14, 16
is connected to the circulation pipe 7a via an inflow flow path switching valve 18, which is a three-way electromagnetic valve, so that it can selectively flow into the circulation pipe 7a. Both heat medium outlets 15 and 17 are connected to the circulation pipe 7b so that they can selectively flow out through an outflow flow path switching valve 19 that is a three-way electromagnetic valve. The inflow flow path switching valve 18 and the outflow flow path switching valve 19 are electrically connected to a hot water temperature detector 20 provided at the top of the hot water storage tank body 10 via a control device 21 . The hot water tank main body 10 has a hot water outlet 22 at the upper end, and a cold water inlet 23 and a drain outlet (not shown) at the lower end. Additionally, the upper split jacket 12 and the lower split jacket 13 each have an air vent valve 2.
4 and 25 are provided.

ことができる。 Next, the operation of this hot water tank will be explained. When the hot water temperature T 1 in the hot water storage tank main body 10 is lower than the set temperature T 2 (for example, hot water supply temperature 45° C.), the inflow is controlled by a control signal sent from the control device 21 based on a detection signal from the hot water temperature detector 20. The flow path switching valve 18 and the outflow flow path switching valve 19 open toward the upper split jacket 12 side.
Therefore, the heat medium circulation path is in the order of the pump 8, the heat collector 6, the upper split jacket 12, and the pump 8, as shown by the thick line in FIG. Therefore, only the portion of the hot water in the hot water storage tank body 10 above the lower edge of the upper split jacket 12 is intensively heated by heat exchange, so that hot water at a high temperature can be quickly obtained.

る。 When the hot water temperature T 1 in the hot water storage tank main body 10 is higher than the set temperature T 2 , the inflow flow path switching valve 18 and the outflow flow path switching valve 19 open toward the lower split jacket 13 side. Therefore, the heat medium circulation path is in the order of pump 8, heat collector 6, lower split jacket 13, and pump 8, as shown by the thick line in FIG. 4B. Therefore, the hot water in the lower temperature portion of the hot water tank body 10 is heated by heat exchange, and the temperature of the water in the hot water tank body 10 is quickly heated to a temperature higher than the set temperature throughout the hot water tank body 10.

The rest is the same as the first embodiment.
