Description of the invention: [Technical field to which the invention pertains] TECHNICAL FIELD The present invention relates to a collection of heat exchange sections and exhaust pipe sections. The 5 degree size of the body is difficult to supply water. [Prior Art] Fig. 5 is an exploded perspective view showing the internal structure of a conventional hot water supply device. 10 15 20 Burner 多数=2 system consisting of a plurality of flat burners 21 and 21 arranged in a flat raft A rectangular combustion chamber 3 is provided, and the upper half of the front end opening 3 of the combustion chamber 3 is closed by the front plate 32. Further, in the burner member 2, the gas distributor i is used for supplying gas. On the other hand, the heat exchanger 4 connected to the opening Μ at the upper end of the combustion chamber 3 is a rectangular tubular casing (9) penetrating vertically, and a plurality of side by side = heat absorbing sheets 41, 41 placed in the casing and The water absorbing tube amp, 41 and the side wall of the outer casing 40 are formed by a water pipe & a core. The exhaust pipe body W connected to the upper end opening 43 of the heat exchanger 4 is formed to be open below and above. Further, as shown in Fig. 6, a gasket 50 is provided between the outer peripheral flange 53 of the r鹆 opening 52 of the exhaust pipe body 5 and the outer peripheral convex table 44 of the upper end of the heat exchanger 4. In this state, the aforementioned two outer peripheral flanges 53 The 44 is connected by a caulking method or a screw, etc. Further, the exhaust port 51 at the downstream end of the body 5 is coupled to the exhaust port cover 6, and the exhaust port cover 6 has a front and rear row. The air cylinder 60. Further, the flange 61 provided around the end portion of the cylinder 60 is attached to the outer peripheral flange 511 of the front end of the exhaust pipe body 5 by screws b and b. The exhaust pipe 60 is inserted into the exhaust window 91 of the front cover 90 which is opened in the hot water supply device casing 9. Patent Document 1: JP-A-2003-21319 (Fig. 1) [Disclosure of the Invention] (Problem to be Solved by the Invention) However, in the above-described conventional hot water supply device, since the heat exchange cry 4 and the exhaust pipe body 5 are composed of independent parts, it is easy to produce in the assembly day temple. 10 In the case of different sizes, the accuracy of the height dimension of the joints of the heat exchanger 4 and the exhaust pipe body 5 may also become poor. Also, due to the heat exchanger 4 and the exhaust pipe body 5 There are 5 衬垫 between the joints, so it is easy to assemble. In the case where the size is different, the accuracy of the height dimension of the joint body of the heat exchange boundary 4 and the exhaust pipe body 5 is also changed by I5. The result of the above various sizes is that the height dimension of the aforementioned joint body is made. The accuracy is further deteriorated. Therefore, for example, the exhaust window sill of the casing 9 and the exhaust pipe 60 of the vent cover 6 are liable to be displaced up and down. As a result, the vent cap is generated when the product is assembled. The exhaust pipe (9) of 6 and the exhaust window 91 of the casing 9 cannot be smoothly fitted. The present invention has been invented in view of the above various problems. A hot water supply is attached to the casing. In the middle, the gas combustion chamber, the heat exchange unit, and the exhaust pipe unit are disposed in order from the bottom, and the heat exchange unit is provided by a plurality of heat absorbing sheets 41 and 41 and a water conduit 42 and 42 penetrating the heat absorbing sheet 4 The heat-absorbing sheet, the heat-receiving sheet, and the second side wall surrounded by the four side walls of the side wall for heat exchange, the side wall for heat exchange, and the side wall for heat exchange are disposed. $ ▲^The exhaust pipe has a row that opens downwards and forwards. The air passage and the exhaust passage are respectively provided by the right wall side of the heat exchange right side wall, the heat exchange left side wall, and the heat exchange rear side wall, the pipe side wall side and the pipe rear wall side, and the pipe top side. The wall of the wall is surrounded by a height, and the height of the connecting body between the heat exchange portion and the exhaust pipe portion is different, so that, for example, the exhaust gas opened on the casing 9 can be prevented. The upper and lower offsets of the relative position between the window 91 and the first ten exhaust cylinders 6 (V) are excessively large. Therefore, the work of fitting the above-described exhaust cylinder 60 and exhaust window 91 can be smoothly performed at the time of assembly. [Invention of Patent Application No. 1] In the first aspect of the invention, the right side wall for heat exchange and the right side wall for the tube are set/group, and the heat exchange is used. The left side wall and the left side wall of the tube are a group, and the rear side wall for heat exchange and the rear side wall for the tube are a group, and each group is composed of one plate. According to the above technique, in the constituent walls of the heat exchange unit and the exhaust pipe portion, the constituent wall systems connected to p are each composed of one plate. Therefore, unlike the above-described conventional members of the heat exchange unit and the exhaust pipe unit that are divided into the upper and lower sides, the height of the entire heat exchanger unit and the exhaust pipe unit is reduced by the silver package. Inconsistent situations. [Invention of Patent Application No. 2] In the invention of the first aspect of the board of the invention, it is possible to make the above-mentioned respective sheets if the front side walls for heat exchange are made of the same material. When the composite sheet or the front wall for heat exchange is composed of a different thermal expansion coefficient or the sheet, the joint between the respective sheets or between the heat 1 and the front (4) for heat reading is heated by the combustion of the gas. Each of the above-mentioned sheets of wolves: = the front side wall will have different extensions of the heat-expanding deer L. The joint between the sheets will produce a great 10 kinds of shapes, the brothers' The joint is prone to long-term damage. In the invention relating to the second aspect of the above patent application, since each of the plates and the front side wall for heat exchange are poisoned by the same material having the same thermal expansion rate, each of the sheets is heated at the same rate when the gas is burned. The expansion does not cause thermal stress on the aforementioned joint portion. Therefore, there is less need to worry about long-term breakage of the above-mentioned joint portion. In the invention of claim 2, the invention relates to the group of the right side wall for heat exchange and the right side wall for the tube, and the above-mentioned enthalpy exchange. The plate of each of the group of the left side wall and the left side wall of the pipe is made of a non-brook steel material and the water pipes 42 and 42 penetrate the right side wall for heat exchange and the left side wall for heat exchange, and the water pipe 42 And the heat absorbing sheets 41 and 41 are made of a copper material, and the through portions of the water conduits 42 and 42 are brazed to the heat absorbing sheets 41 and 4, respectively. Because the right side wall for heat exchange and the left and right plates of the left side wall for heat exchange are made of stainless steel, the mechanical strength can be improved when compared with the case of using copper material. Therefore, the hot water supply 8 1275755 can be reduced in shipment. In addition, since the above-mentioned one plate is made of a stainless steel material, the heat resistance can be improved and the long-term deterioration can be suppressed as compared with the copper material. Further, in the invention of claim 3, since the penetration portion of the water conduit and the 528 is not substantially fixed to the respective one of the plates constituting the right side wall for heat exchange and the left side wall for heat exchange, the above-mentioned one is Even if the water pipes 42 and C are thermally expanded and contracted in the longitudinal direction, thermal stress does not occur in the above-mentioned penetrating portion, and there is no need to worry about damage of the heat exchange portion. That is, the heat absorbing sheets 41 and 41 of the copper material are used as the water conduit 42. 1 and 42 are connected to each other by brazing, but the heat absorbing sheets 41 and 41 and the water tubes 42 and 42 are generally brazed by a heating furnace as follows. That is, the water pipes 42 and 42 pass through the heat absorbing. The sheet groups 41 and 41 are provided with a hard-welded material at the boundary between the outer edges of the water-passing pipes 42 and 42 and the heat-absorbing sheets 41 and 41 at the penetration portion. Further, the right side wall for heat exchange and the heat exchange are used. A plate (made of stainless steel) on the left and right sides of the left side wall penetrates both end portions of the water conduits 42 and 42 to heat the assembly of the pair of left and right plates, the water pipes 42 and 42 and the heat sheets 41 and 41 in this state. Heating in the furnace to melt the aforementioned hard The heat-absorbing sheets 41, 41 and the water-passing members 42, 42 are brazed by the brazing of the brazing material, but since the left and right plates are made of stainless steel, 20 even if a hard-welded material flows into the piece The through-holes of the water pipes 42 and 42 of the board are substantially not brazed to each other by the aforementioned one of the plates and the water pipes 42, 42. The reason is that the brazing material can be connected to the heat absorbing sheets 41, 41 made of copper material and The water pipes 42 and 42 cannot substantially connect the left and right plates and the water pipes 42 and 42 made of stainless steel. 9 Ϊ 275755 Therefore, the water pipes 42 and 42 repeatedly expand in the longitudinal direction due to the combustion of the gas and the bonfire. At the time of contraction, the water conduits 42 and 42 in the penetration portion slide with respect to the one plate, so that no excessive force acts on the penetration portion. Thereby, the heat exchange portion 5 can be prevented from being damaged. [Invention of the Patent Application No. 4] In the invention of the first to third aspects of the invention, the group of the right side wall for heat exchange and the right side wall for the tube, the left side wall for heat exchange, and the tube are used. The group of the left side wall, the front side wall for heat exchange, and the group of the rear side wall of the tube 10 are connected to each other at the boundary portion in the circumferential direction by caulking. Since the joint portions between the sheets are connected by a high airtight caulking method, a gasket is not particularly required to ensure the airtightness of the joint portion, and the number of parts can be reduced. [Invention of the Patent Application No. 5] In the invention of the first to fourth aspects of the invention, the pipe top wall of the exhaust pipe portion constitutes the group of the rear side wall for heat exchange and the rear side wall for the pipe. The aforementioned board extends to form the 』. In the hot water supply, since the top wall for the pipe and the rear side wall for the pipe and the rear side wall for heat exchange are each composed of one plate, only one of the plates is subjected to a bending process to form the top wall for the pipe or the rear side wall for the pipe. There is no need to use special work to connect the top wall of the pipe and the rear side wall of the pipe. [Invention of Patent Application No. 6] In the invention of claim 1 to 5, the front wall for heat exchange is detachably mounted by screws to constitute the heat exchange 10 1-275755. The right side wall and the group of the right side wall for the tube and the board of each of the group of the left side wall for heat exchange and the left side wall for the tube are disposed. The front side of the heat exchange can be removed by removing the screw, so the internal maintenance of the heat exchange unit can be easily performed. [About the invention of claim 7] In the invention of claim 1 to 6, the exhaust port cover is connected to the exhaust port 51 at the downstream end of the exhaust passage of the exhaust pipe portion. 6 and the front side wall for heat exchange are constituted by a single plate, and the exhaust pipe 10 cylinder 60 projecting forward from the exhaust port cover 6 is formed by drawing the plate. 』. Since the exhaust cylinder 60 can be formed by the extension of the work force, it is not necessary to manufacture the front side wall for heat exchange and the separate exhaust port cover 6, which not only reduces the number of parts but also simplifies part management. [Invention of Patent Application No. 8] In the invention of the first to seventh aspects of the patent application, the "the watts 15 s combustion chamber is composed of a right side wall for a combustion chamber and a left side wall for a combustion chamber and a combustion chamber. The side wall and the rear side wall of the combustion chamber are surrounded by a space for opening the burner member device and opening upward, and the right side wall for the combustion chamber and the right side wall for heat exchange are a group, and the left side wall of the combustion chamber is used. And a pair of the left side wall for heat exchange, the front side wall for the combustion chamber, and the front side wall for the heat exchange 20, and the rear side wall for the combustion chamber and the rear side wall for heat exchange are a group, and each group They are made up of one board. 』. Since the wall formed by the gas combustion chamber and the exhaust pipe portion is constituted by one plate which is continuous in the vertical direction, the height of the entire hot water supply can be improved. 1275755 [Effects of the Invention] The present invention has the following specific effects. 5 15 20 In the constituent walls of the heat-reading portion and the exhaust pipe portion, the upper and lower connecting members are configured by separate plates, and thus are different from the conventional ones of the heat exchange h & In addition, the height of the junction of the heat exchange unit and the exhaust pipe unit, the height of the phase, and the like, are reduced, and the size of the carcass can be improved. In the invention of the first and second paragraphs, since each of the panels is replaced by the same material with the same thermal expansion rate, it is accompanied by the wattage, the flameout, and the thermal expansion of the various temples at the same ratio = 1: Crossing, no thermal stress is generated on the joint portion of the side wall, and the long-term damage of the joint portion is described. In the invention relating to the third paragraph of the patent application, since the right side wall of the right side wall or the left side wall for heat exchange is made of a material, it is compared with a piece of steel material: a piece: = steel and When the copper material is composed, the heat resistance is better ==. Deterioration. Further, as described above, the above-mentioned left and right "42" temporary 并 并 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 Excessive force ί will not act on the Beton section of the water pipes 42 and 42 of a board which is about 12 1 to prevent breakage of the heat exchange unit. In the fourth paragraph of the patent application, the mutual interconnection is linked by a high airtightness. Therefore, the number of special parts is required to be cushioned to ensure the airtightness of the joint.
