することができないという欠点があつた。Conventional structure and problems With regard to an example of a hot water heater with reheating function shown in Fig. 1, a heat exchanger 1 is housed in a heat exchanger case 2, which is connected to a bathtub 3. Since wastewater and foreign matter from the bathtub 3 are likely to invade, adhere, stagnate, and accumulate on the inner surfaces of the heat exchanger 1 and heat exchanger case 2, the material of the heat exchanger case 2 is made of resin to prevent this. Also, from the viewpoint of structure, it is desirable for the heat exchanger 1 to be easily attached and detached and to be easily cleaned, but conventionally, the attachment of the heat exchanger 1 to the resin heat exchanger case 2 was generally performed by fastening the heat exchanger 11 having a screw-in flange 11a to the heat exchanger case 12 using an O-ring packing 10 as shown in Fig. 2.
In this case, since the screw-in flange 11a is a round flange and there is a size limit, attachment and detachment are relatively easy, but the opening of the heat exchanger mounting port 13 of the resin heat exchanger case 12 is relatively small, so there is a disadvantage that the inner surface of the resin heat exchanger case 12 cannot be reliably cleaned.

When the screws 18 are inserted into the mounting surface 17' of the heat exchanger 15 and the heat exchanger 15 is fixed with screws, the insert screws 18 of the resin heat exchanger case 17 are fixed, but the space between the screws 18 and 18 is The resin expands due to the creep phenomenon caused by the temperature of the hot water, creating a gap between the gasket 16 and the heat exchanger mounting surface 17', resulting in water leakage.

ト２５ａにより固定する構成である。 Reference numeral 20 denotes a heat exchanger having a mounting plate 20' having screw holes fixed by screws 25 as clamping tools. 22 is a resin heat exchanger case, and has flanges 2 that are flat on both sides as heat exchanger mounting surfaces.
2' and a heat exchanger insertion port 22''.Heat exchanger 2
0 is fixed between the mounting plate 20' and the flange 22' of the resin heat exchanger case 22 with a first packing 21 interposed therebetween using screws 25 and nuts 25a (pinch clamps).
On the back side of the flange 22' of the resin heat exchanger case 22, there is a rectangular metal fixture 24 with an L-shaped cross section and a second gasket 23 and mounting screws 25, and the fixture 24 is attached to the flange 22'. They have substantially corresponding planes, and are attached to the back surface of the flange 22' through the second gasket 23, and are configured to fix the mounting plate 20' together with the first gasket 21 using screws 25 and nuts 25a. .
この時第１のパツキン２１と第２のパツキン２
３は取付具２４側に取付ける第２のパツキン２３
の方の硬度を高く設定されている。 At this time, the first packing 21 and the second packing 2
3 is a second gasket 23 that is attached to the fixture 24 side.
The hardness is set higher.
又、取付具２４は樹脂製熱交換器ケース２２の
フランジ２２′の成型肉厚が偏肉バラツキが大き
い時は図の様に各辺ごとに分割した構成とした方
が良い。 Further, when the molded thickness of the flange 22' of the resin heat exchanger case 22 has large variations in thickness, it is better to configure the fixture 24 to be divided into each side as shown in the figure.
なお、樹脂製熱交換器ケース２２は第１図のご

れるようになつている。 Note that the resin heat exchanger case 22 is installed below the boiler 4 as shown in FIG.
At that time, a heat insulating material 22a made of styrene foam or the like is installed on the lower surface thereof, as shown in FIG. 5, also serving as a reinforcing material. This heat insulator 22a is attached to the mounting leg 2.
It is designed to be held down by mounting pieces a and b integrated with 6 and 27.

が加わることもない構成となつている。 Furthermore, the mounting legs 27 of the resin heat exchanger case 22
As shown in Figure 6, the side bottom surface has embedded screws 28,
Since the space between 29 and 29 is convex upward, when the hot water inside the case 22 becomes high temperature, the water expands and rises as shown by the broken line and absorbs the water, which causes the screws 28, 29 and the mounting legs to be absorbed. The structure is such that no excessive force is applied to the 27 fixed parts.

密性を向上させる結果となる。 In the above structure, the first packing 21 maintains watertightness between the mounting plate 20' and the flange 22'. In addition, the second gasket 23 is attached to the mounting tool 2.
4 and the back surface of the flange 22', but since the second packing 23 is set to have a higher hardness than the first packing 21, it feels like one with the fitting 24, and the strength of the fitting 24 makes the flange 22 'On the back side, uneven molding thickness is also absorbed by the second packing 23 along the fixture 24. Moreover, the flange 22' is connected to the first packing 21 and the second packing 2.
3. It is sandwiched between the mounting plate 20' and the mounting fixture 24, so it is completely sealed, and the flange 2
Since the end face 2' is also fixed, expansion due to thermal creep of the resin does not result in deformation, and pressure is applied due to expansion of the first and second packings 21, 23, resulting in further improvement of watertightness.

の厚さを必要としない。 In addition, by dividing the fitting 24, variations in the uneven thickness of the flange 22' are also divided, so the burden of compressibility on the first and second packings 21 and 23 is reduced, and the appropriate thickness can be selected. There is no need for greater thickness.

Since the structure is clamped on a flat surface, the flange of the resin heat exchanger will not be deformed by the heat of the hot water, and therefore the flange of the heat exchanger mounting plate and the flange of the heat exchanger case can be maintained for a long period of time. It can be kept completely watertight for a long time.
