なる、(b)接合面３０より水漏れのおそれがある、
(c)製作や組立てに時間がかかる、(d)部品点数が増
える、(e)重量が増加する等の欠点があつた。 A conventional hot water tank is shown in Figure 1. That is, the tank body 13 forming the hot water tank is divided into a head plate part 8 and a body part 9, and a plurality of flanges 10 are attached to the outer periphery of the joint surface 30 of the head plate part 8 and the body part 9, respectively. Tank body 1
The purpose of dividing 3 is to simplify the installation and inspection work of the spiral body 14 that performs heat exchange, and the corresponding flanges 10 of the end plate 8 and body 9 are screwed together with bolts 11 and nuts 12. The end plate portion 8 and the body portion 9 are joined together. 2 in the figure is a water supply port drilled at the bottom of the body 9, and this water supply port 2
Colder water flows into the tank body 13. The cold water is supplied by a heater 4 installed near the water supply port 2.
The hot water is heated to become hot water, and this hot water is supplied to the outside of the tank body 13 from a hot water outlet 3 formed in the upper surface of the end plate part 8. Reference numeral 14 denotes a helical body 14 which is formed by spirally bending a single pipe body, and is disposed inside the tank body 13. This spiral body 14 is fastened with cap nuts 19 to an inlet 17 and an outlet 18 formed at key points in the body 9 of the tank body 13. that's why,
The endothermic fluid flowing into the tank body 13 from the pipe end 28 through the inlet 17 absorbs heat from the surrounding hot water and becomes high temperature, and flows out from the pipe end 28 to the outside of the tank body 13 through the outlet 18 and generates heat. This completes the exchange. However, in this conventional example, the end plate portion 8
Since the flange 10 is used to join the body 9 and the body 9, the flange 10 is attached to each of the end plate 8 and the body 9.
(a) The outer diameter of the hot water tank will become larger. (b) There is a risk of water leaking from the joint surface 30.
There were disadvantages such as (c) it took time to manufacture and assemble, (d) the number of parts increased, and (e) the weight increased.

ため、(A)故障時修理ができない、(B)清掃しにくい
等の欠点があつた。 Further, FIG. 2 shows another conventional example in which the above-mentioned flange 10 is removed. That is, instead of the flange 10, the end plate part 8 and the body part 9 are joined by welding.
Further, both ends of the spiral body 14 used for heat exchange, the inlet 17, and the outlet 18 are joined by welding. However, in this conventional example, since the spiral body 14 used for heat exchange cannot be replaced, there are disadvantages such as (A) it is impossible to repair it in the event of a failure, and (B) it is difficult to clean.

Slanted surfaces 2 that are slightly inclined and orthogonal to each other
2 and 23. One inclined surface 22 of this concave stepped portion 5 is aligned with the surface including the axis of the hot water tank main body 1, and the rear end of the heat exchanger 6 is placed outside the hot water tank main body 1 at key points of this inclined surface 22. A conduction port 7 for leading out is provided. Hot water tank body 1
A heater 4 is disposed inside near the water supply port 2, and heats the cold water flowing into the hot water tank main body 1 from the water supply port 2 to make it hot water. This hot water is supplied from the sprue 3 to the outside of the hot water tank body 1. Outbound pipe 15 and return pipe 1
6 are arranged parallel to each other, and the tips of the outgoing pipe 15 and the returning pipe 16 are connected to form a tube body. This tube body is spirally bent to form a heat exchanger 6, and this heat exchanger 6 is provided inside the hot water tank main body 1. The rear end of the heat exchanger 6 is led out to the outside of the hot water tank main body 1 through a communication port 7 formed in the inclined surface 21 of the recessed step 5. FIG. 4 shows an enlarged sectional view of the joint 31 between the heat exchanger 6 and the hot water tank main body 1. A gasket 25 is attached to a conduction port 7 formed at a key point on the inclined surface 21 of the recessed step portion 5 of the hot water tank main body 1. This packing 25 has an outgoing pipe 15 and a returning pipe 1.
Passage holes 24, 24 of No. 6 are bored, and the outgoing pipe 15 and the returning pipe 16 are led out of the hot water tank main body 1 through these holes 24, 24. Furthermore, the gasket 25 includes the hot water tank body 1 and a screw hole 32 for screwing.
32 is drilled, and the packing 25 is attached with the attachment bolt 26.
and the hot water tank body 1 are screwed together. The heat exchanger 6 configured as described above is inserted into a hot water tank as follows. As shown in FIG.
The tip of the heat exchanger 6, which has been previously inserted into the rear end of the tank, is inserted into the through hole 7 formed in the recessed step 5 of the hot water tank main body 1 and rotated. The heat exchanger 6 is screwed into the hot water tank main body 1 by rotation, and is disposed inside the hot water tank main body 1 with the rear end, where the gasket 25 is inserted, left behind. Thereafter, the gasket 25 is press-fitted into the through hole 7 and screwed in with the attachment bolt 26. Thus, the endothermic fluid flows into the outgoing pipe 15, runs in a spiral shape inside the hot water tank main body 1, and during its running, absorbs heat from the surrounding hot water and becomes high temperature, and the endothermic fluid becomes high temperature. The heat exchange is completed by allowing the heat to flow out from the return pipe 16.

That is, instead of the heat exchanger 6 shown in FIG. 3, a concentric pipe body 35 is used in which an outgoing pipe 34 is disposed inside an incoming pipe 33 to form a concentric double structure. As shown in FIG. 6B, the forward pipe 34 and the return pipe 33 are connected by forming the forward pipe 34 so as to surround its tip with the return pipe 33. The pipe body 35 is screwed into the hot water tank main body 1 in the same manner as in the first embodiment, and is screwed onto the hot water tank main body 1 with the attachment bolt 26 via the packing 25. If the endothermic fluid flows in through the outward pipe 34 and flows out through the return pipe 33, the same objective as in the first embodiment can be achieved.

ず、容易に行えるという効果がある。 As mentioned above, the present invention forms the hot water tank main body with a hollow, single cylindrical body, and has a water inlet and a hot water outlet drilled on the outer surface of the hot water tank main body, as well as a hole near the water inlet inside the hot water tank main body. In a hot water tank using a spiral heat exchanger, in which a heater is installed and a spiral heat exchanger is arranged concentrically within the hot water tank body, the outgoing pipe and the returning pipe are integrally installed side by side. A heat exchanger is formed by spirally bending a tube body with the tips of each connected.
A recessed step portion opening downward and laterally is formed at one location on the bottom circumference of the hot water tank main body, and one side of the recessed step portion is made to substantially coincide with a surface including the axis of the hot water tank main body,
A through hole is drilled on one side of the heat exchanger to lead the rear end of the heat exchanger to the outside of the hot water tank body, and while rotating the heat exchanger, the heat exchanger is screwed into the hot water tank body through the through hole. The end is removably attached to the conduction port, and the hot water tank body is formed from a single, hollow cylindrical body, so the flange can increase the diameter of the hot water tank body and prevent water from flowing out from the joint. There is no risk of leakage, and the heat exchanger is formed by arranging the forward and return pipes side-by-side and connecting their tip ends in a spiral shape to form a heat exchanger. The rear end of the heat exchanger is screwed into the hot water tank body through the through hole drilled on one side of the concave step formed in one place while rotating the heat exchanger, and the rear end of the heat exchanger is inserted into the through hole. Since it is attached removably, the heat exchanger can be easily attached and detached in the event of failure or cleaning without requiring any special tools or work.
