る。Conventional configuration and its problems Figure 1 shows a typical configuration of a water heater that uses other heat sources. A heat storage tank 1 has a built-in heater 2 as an auxiliary heat source for additionally boiling the hot water in the tank. 3 is a circulation path for circulating water in the tank 1; 4 is another heat source device such as a heat pump; 5 is a refrigerant circulation path; the circulation paths 3 and 5 are connected to enable heat exchange through a heat exchanger 6. The water in the circulation path 3 is heated by absorbing the heat of the refrigerant heated by the other heat source device 4. 7
8 is a pump installed in the circulation path, and 8 is a hot water supply faucet.
上記のように、他熱源機を利用した給湯機は、

していた。 As mentioned above, water heaters that use other heat sources,
The length of the water circulation path where heat is exchanged with other heat source equipment is constant, and the boiling by the other heat source equipment is also constant.
Therefore, when changing the boiling water temperature, the assistance of an auxiliary heat source was required. Therefore, this was inconvenient in terms of energy saving. Also, place the heat exchanger on top of the heat storage tank.
Since it is disposed at the bottom or on the side, the piping for the water circulation path for heat exchange becomes long, resulting in problems such as heat loss due to heat radiation and freezing of the water circulation path in winter.
考案の目的
本考案は、上記のような従来の欠点を解消し、
補助熱源無しでも蓄熱槽内の沸上げ温度の可変を
行える給湯機を提供することを目的とする。Purpose of the invention The present invention eliminates the conventional drawbacks as mentioned above,
To provide a water heater capable of varying the boiling temperature in a heat storage tank without an auxiliary heat source.
考案の構成
本考案は、蓄熱槽内の水を循環する水循環路を

である。Structure of the invention The present invention consists of a water circulation path that circulates water in a heat storage tank, a water circulation path and a refrigerant circulation path that are arranged side by side and in close contact with each other to enable heat exchange with other heat source equipment, and are spirally wrapped around the outer periphery of the heat storage tank. A water passage is provided in the middle of the water circulation passage to partially short-circuit the water circulation passage through a switching valve.

ので熱交換性能が向上する。 According to this configuration, by changing the length of the water circulation path that exchanges heat with the other heat source device, the temperature of the hot water in the heat storage tank can be varied without using an auxiliary heat source. In addition, because the water circulation path for exchanging heat with other heat source equipment is spirally wrapped around the side of the heat storage tank, the heat radiated from the heat exchanger is absorbed into the heat storage tank, reducing heat loss due to heat radiation and saving energy. It is also advantageous in that respect. Furthermore, in winter, it receives conductive heat from the hot water in the heat storage tank, giving a heat-retaining effect to the water circulation path.
It has the effect of preventing freezing. Moreover, the space for installing the heat exchanger can be greatly reduced. Furthermore, since the water circulation path and the refrigerant circulation path are arranged in close contact with each other and the water in the heat storage tank is directly circulated, heat exchange performance is improved.
実施例の説明
以下、本考案の一実施例を第２図により説明す
る。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.
第２図において、１０は蓄熱槽、１１はその上

環路１２と熱交換可能に並設密着させて、蓄熱槽
１０の外周に螺旋状に巻きつけてある。 In FIG. 2, 10 is a heat storage tank, and 11 is a hot water supply path provided above the heat storage tank. 12 is a water circulation path equipped with a pump 13, one end of which is connected to the lower part of the heat storage tank 10, the other end of which is connected to the hot water supply path 11 side, and is spirally wound around the outer periphery of the heat storage tank 10. A water passage 14 is connected to the water circulation passage 12 via electric three-way valves 15 and 16, and is provided so as to partially short-circuit the circulation passage 12. 17 is another heat source machine,
Reference numeral 18 denotes a refrigerant circulation path, and the circulation path 18 is arranged in close contact with the water circulation path 12 to enable heat exchange, and is spirally wound around the outer periphery of the heat storage tank 10.

長さが変化し、沸上げ湯温を可変することができ
る。 In this water heater, by switching the valves 15 and 16, not only can the entire length of the water circulation path 12 be used for heat exchange with another heat source device 17, but also the water circulation path 12 can be used for heat exchange with another heat source device 17.
The lower part of the circulation path 12 is short-circuited by the water passage 14, and heat can be exchanged with other heat source equipment only through the upper part of the circulation path 12. Therefore, when storing hot water in the heat storage tank 10, the electric three-way valve 1
By switching between 5 and 16, the length of the heat exchanger portion can be changed and the boiling water temperature can be varied.
このようにすれば、補助熱源機の助けをかりる

ているので熱交換性能が向上する。 In this way, the temperature of the hot water in the heat storage tank 10 can be varied without the aid of an auxiliary heat source device, and energy saving can be improved.
Furthermore, since the heat radiation generated when exchanging heat with other heat sources is absorbed into the heat storage tank, heat loss due to heat radiation can be reduced. Furthermore, in winter, it is possible to prevent the water circulation path 12 from freezing, and it also has the effect of reducing the space required for installing the heat exchanger. Furthermore, since the water circulation path and the refrigerant circulation path are arranged in close contact with each other and the water in the heat storage tank is directly circulated, heat exchange performance is improved.
