ず充分な効果を得ていなかった。Structure of the conventional example and its problems A conventional hot water storage tank of this type is shown in Fig.
As shown in No. 41 (a hot water outlet pipe 2 with a large number of small holes facing downward is provided in the middle part of the hot water storage tank 1, the hot water is passed from the lower part of the hot water storage tank 1 through the heat exchanger 4 of the heat source part 3). With a configuration that allows more heated water to flow out, the flow rate of the circulation pump 5 is controlled, and when high-temperature hot water is required quickly, the flow rate is reduced and the upper part is heated using a draft, when a large amount of hot water is required. The flow rate was increased to mix and heat the entire body. However, in this method, the upper part is water and the water is heated from the middle, and the cold water in the upper part and the heated high-temperature water in the middle part mix. Therefore, as shown in Fig. 2, the temperature rise in the entire upper part was not sufficiently effective even though the aim was to quickly extract high-temperature water!7.

る。In the above configuration, when the entire hot water storage tank 1 is in an unheated state,
The temperature sensor 12 detects the low temperature, switches the three-way flow path switching valve 6 to the top inflow pipe 7 side, and transfers water from the lower part of the hot water tank 1 to the water heat exchanger 4.
' is heated to a predetermined temperature, and the hot water is introduced from the top of the hot water storage tank 1 to replace the constantly heated area AI water with high temperature hot water. For small-scale hot water supply, the temperature sensor 12 constantly monitors the temperature of area A, and controls the entire area A to a predetermined temperature by injecting heated water from the top. Next, when the temperature sensor 12 detects a predetermined temperature or higher during bath heating, it is determined that area A is filled with high-temperature hot water, and the flow path switching valve 6 is switched to the intermediate inflow pipe 8 side. ) Heated water flows into heating area B from IJ Buke 2' during bathing and replaces the water. In addition, if the temperature detector 12 detects a temperature below a predetermined temperature, first let heated water flow in from the top, and after confirming with the temperature sensor 12 that area A has reached the predetermined high temperature, the flow path switching valve 6 is switched to an intermediate inlet. Switch to the tube 8 side and heat area B in the same way. Here, if you need to reheat the bath in winter, etc., set the A area to high temperature and B.
It is also possible to heat the whole area separately at medium temperatures lower than the A area.
第４図に本発明の一実施例における常時加熱域の高温湯
早採９効果を示す。第２図の従来例の温度の立上り特性
と比較して明らかなように高温湯早採り効果が向上して
いる。これは本発明は高温湯と低温水の混合がなく高温
湯が温度成層化して水と置換することによる。FIG. 4 shows nine effects of rapid hot water extraction in the constant heating region in one embodiment of the present invention. As is clear from the comparison with the temperature rise characteristics of the conventional example shown in FIG. 2, the effect of rapidly drawing high-temperature water is improved. This is because in the present invention, there is no mixing of high-temperature hot water and low-temperature water, and the high-temperature hot water undergoes temperature stratification and replaces water.
