Description of the invention: [Technical field to which the invention belongs] TECHNICAL FIELD The present invention relates to a hot water supplier that can improve the precision of the south dimension of the assembly of the heat exchange section and the exhaust pipe section. [Prior Art] FIG. 5 is an exploded perspective view of the internal structure of a conventional hot water supply. The burner 10 consisting of a plurality of flat burners 21 and 21 arranged in parallel is housed in a rectangular combustion box 3, and at the same time, the upper half of the opening 30 at the front end of the combustion box 3 is made by a front plate 32 Occlusion. Also, in the burner member 2, the gas distributor 1 is used to supply gas. On the other hand, the heat exchanger 4 connected to the opening 31 at the upper end of the combustion box 3 is composed of a rectangular cylindrical casing 40 penetrating up and down, and a large number of 15 heat sinks 41 and 41 arranged side by side in the casing and penetrating through the casing. The heat absorbing sheet 41 and 41 and the water passing pipes 42 and 42 on the side wall of the casing 40 are configured. The exhaust pipe body 5 connected to the opening M provided at the upper end of the heat exchanger 4 is formed in a rectangular box shape with an open state below and above. Further, as shown in Fig. 6, there is approximately 50 between the outer peripheral flange 53 opened at the lower end of the exhaust pipe body 5 and σ 20 and the outer peripheral flange 44 at the upper end of the heat exchanger 4. In this state, the two outer peripheral flanges 53 and 44 are connected by a chiseled square or a screw. In addition, the exhaust port 51 at the end of the exhaust pipe body 5 is connected to the exhaust port cover 6, and the exhaust port has an exhaust tube 60 which passes through the front and rear. In addition, the flange 61 provided at the end of the exhaust pipe 60 adjacent to the periphery 5 200535386 is fixed to the outer peripheral flange 511 at the front end of the exhaust pipe body 5 by screws b, b, and the exhaust pipe 60 is also It is freely inserted into the exhaust window 91 opened in the front cover 90 of the hot water supply case 9. Patent Document 1: Japanese Patent Application Laid-Open No. 2003-21319 (Figure 1) 5 [Summary of the Invention] [Disclosure of the Invention] (Problems to be Solved by the Invention) However, in the conventional hot water supplier, the heat exchanger 4 The exhaust pipe body 5 and the exhaust pipe body 5 are composed of independent parts, so it is easy to produce 10 different sizes during assembly, and the accuracy of the height and size of the connected body of the heat exchanger 4 and the exhaust pipe body 5 will also be Become poor. In addition, since the gasket 50 is provided between the connecting portion of the heat exchanger 4 and the exhaust pipe body 5, it is easy to cause different sizes during assembly, and the heat exchanger 4 and the exhaust pipe body 5 The accuracy of the height dimension of the connected body will also change by 15 degrees. As a result of the accumulation of the above-mentioned various sizes, the height dimensional accuracy of the aforementioned connected body is further deteriorated. Therefore, for example, a vertical displacement between the exhaust window 91 of the casing 9 and the exhaust cylinder 60 of the exhaust port cover 6 is likely to occur. As a result, a problem arises in that the exhaust tube 60 of the exhaust port cover 6 and the exhaust window 91 of the casing 9 cannot be smoothly fitted when the product is assembled. 20 The present invention has been invented in view of the foregoing problems. "A hot water supply device is one in which a gas combustion chamber, a heat exchange section, and an exhaust pipe section are sequentially arranged in the casing from below, and the heat exchange section is composed of a plurality of heat absorbing sheets 41 and 41 and penetrates through The heat absorbing plates 41 and 41 are composed of water passing pipes 42 and 42. The heat absorbing plates 41 and 6 200535386 41 are arranged on the right side wall for heat exchange, the left side wall for heat exchange, the front side wall for heat exchange, and the rear side for heat exchange. In the rectangular space surrounded by the four side walls of the side wall, the exhaust pipe portion has exhaust passages that open downward and forward, and the exhaust passages are respectively formed from the right side wall for heat exchange and the heat exchange side. The left wall and the rear wall for heat exchanging are surrounded by the right wall side of the tube, the left wall side of the tube and the back wall side of the tube, and the four walls of the top wall of the tube. " The heights of the connecting bodies between the tube sections are different, and for example, it is possible to prevent the upper and lower positions of the relative positions between the exhaust window 91 and the exhaust pipe 60 described above from being opened in the housing 9 from being excessively shifted. Therefore, the work of fitting the exhaust tube 60 and the exhaust window 91 described above can be smoothly performed during assembly. [Invention under the scope of patent application No. 1] The 15 technical methods related to the invention under the scope of patent application No. 1 to solve the above problems are "the right side wall for heat exchange and the right side wall for tube as a group, and the aforementioned heat exchange The left side wall and the left side wall for the tube are a group, and the rear side wall for the heat exchange and the back side wall for the tube are a group, and each group is composed of a board. With the above-mentioned technology, among the constituent walls of the heat exchange section and the exhaust pipe section, 20 constituent walls that are connected up and down are each composed of a plate. Therefore, it is different from the aforementioned one that combines the heat exchange section and the exhaust pipe section which are divided up and down, and it is possible to reduce the inconsistency of the entire height of the joint between the heat exchange section and the exhaust pipe section due to assembly errors and the like. Happening. [About the invention in the second scope of the patent application] 7 200535386 In the invention in the first scope of the patent application, "the aforementioned pieces of boards and the front wall for heat exchange can be made of the same material. 』Each plate on the right or the front wall for heat exchange is made of other materials with different thermal expansion coefficients. When the gas is heated, the plates are heated or the connection between the plate and the heat father is replaced by the front wall. Each piece of board or thermal parent changes the front side wall to produce different degrees of thermal expansion.

In response to this situation, related to the above-mentioned patent application scope No. 2 In the invention, since each of the plates and the front wall for heat exchange are made of the same material with the same thermal expansion coefficient, so each plate will be thermally expanded at the same rate when the gas is burned. Thermal stress acts on the surface. Therefore, it is' less necessary to worry about the long-term damage of the above-mentioned connection part. [About the invention of the scope of patent application No. 3] About the invention of the scope of patent application No. 1 or 2, the "composition month The plate of each group of the right-hand wall for heat exchange and the right-hand wall for pipes and the left-hand wall for heat-exchange and the left-hand wall for pipes are made of stainless steel, and the water passing pipes 42 and 42 pass through the above The right side wall for heat exchange and the left side wall for heat exchange, and the water passing pipes 42 and 42 and the heat absorbing sheets 41 and 41 are made of steel, and the water passing pipes 42 and 42 are made of steel. The Beton unit is connected to the aforementioned heat sinks 41 and 41 by brazing. The hot water supply can be reduced in this hot water supply because the right and left panels of the right wall for heat exchange and the left wall for heat exchange can be reduced. Because it is made of stainless steel, it can improve the mechanical strength when compared with copper material. Therefore, 8 200535386 is damaged by the impact during shipment or installation. Also, because the above board is made of stainless steel, Compared with steel materials, it can improve heat resistance and suppress long-term deterioration. In addition, in the three inventions of the scope of the patent application, the penetrations of the water pipes 42, 5 and 42 are not substantially. It is fixed to each of the uranium plates constituting the right wall for heat exchange and the left wall for heat exchange. Therefore, even if the water passing pipes 42 and 42 are repeatedly thermally expanded and contracted in the long direction, thermal stress does not occur in the penetration portion. There is no need to worry about the heat exchange section being damaged. That is, 'Although the heat sinks 41, 41 water pipes 42, 10 42 made of copper material are connected to each other by brazing, these heat sinks 41, 41 The water pipes 42 and 42 are generally brazed with a heating furnace as follows. That is, the 'water pipes 42 and 42 penetrate the heat absorbing sheet groups 41 and 41, and the outer edges of the water pipes 42 and 42 located at the side penetration portion and the heat absorbing sheet. A brazing material is appropriately sandwiched at the boundary between 41 and 41. In addition, a plate (made of stainless steel) constituting the right side wall for heat exchange and the left side wall for heat exchange 15 is replaced by both ends of the water passing pipes 42 and 42 In this state, the assembly of the left and right pair of plates, the water pipes 42, 42 and the heat absorbing sheets 41, 41 in this state is heated in a heating furnace to melt the aforementioned hard and dry material. The brazing material is melted and connected by brazing. The heat sinks 41, 41 and Tongshui Di 2 are made of stainless steel, because the left and right boards are made of stainless steel. 20 Even if the brazing material flows into the through pipes 42 and 42 of the board ~ The plate and the water pipe 42 and 42 are not substantially connected by brazing. The reason is that the brazing material can connect the heat absorbing sheet 41 made of copper material and the water pipes 42 and 42, but cannot substantially connect the left and right plates made of stainless steel with the water pipes 42, 42. 9 200535386 Therefore, with the combustion and flameout of gas, when the above-mentioned water pipes 42 and 42 repeatedly thermally expand and contract in the length direction, the water pipes 42 and 42 in the through part will slide relative to the aforementioned board, so there will be no Excessive force acts on the penetrating portion. This prevents damage to the heat exchange section 5. [Regarding inventions in the scope of patent application No. 4] In the inventions in scope of patent applications Nos. 1 to 3, "the group consisting of the right-side wall for heat exchange and the right-side wall for tubes, the left-side wall for heat-exchange, and the tube The plates of each group of the left wall group, the rear wall for heat exchange and the rear wall for the tube 10 are connected to each other at the boundary portion in the peripheral direction by the caulking method ". Since the connecting portions between the above-mentioned sheets are connected by a caulking method with high air tightness, a gasket is not particularly required to ensure the air tightness of the connecting portion, and the number of parts can be reduced in this way. [About the invention in the scope of patent application No. 5] 15 Among the inventions in the scope of patent application Nos. 1 to 4, "the top wall of the exhaust pipe part constitutes the group of the aforementioned rear wall for heat exchange and the rear wall for tube The aforementioned board extension former ". In this hot water supplier, since the top wall for pipes and the back wall for pipes, and the back wall for heat exchange are each composed of a single plate, the above-mentioned top wall for pipes or the back wall for pipes can be formed only by performing a bending process on the one plate. It is not necessary to have special work to connect the top wall for pipes and the back wall for pipes, etc. [About the invention in the sixth scope of the patent application] In the inventions in the first to fifth scope of the patent application, "the front side wall for heat exchange is detachably mounted on the right side wall constituting the aforementioned heat exchange 10 by screws." And the group of the right side wall for the tube, and the boards constituting each group of the group of the left side wall for the heat exchange and the group of the left side wall for the tube.

The assembly system is supported by the fixture 18. Then, the assembly was heated in a heating furnace to melt the aforementioned brazing materials 100 and 100. In this way, the heat-absorbing sheets 41, 41 and the water-passing pipes 42, ^ can be brazed and connected by the molten hard saffron materials 100, 100, but the right-side wall 45 for heat exchange or the left-side wall 46 for heat exchange is made of stainless steel. Even if the brazing material 100 flows into the through-pipes 42 and 42 which are in contact with the right-side wall 10 45 for heat exchange or the left-side wall 46 for heat exchange, a heat sink such as 父 HAI uses the right-side wall 45 or heat. The exchange-side left wall 40 cannot be substantially brazed to connect the water pipes 42 and 42. Therefore, with the ignition and flameout of the burner member 2 to be described later, when the water-passing pipes 42 and 42 repeatedly expand and contract in the longitudinal direction, the water-passing pipes 42 and 42 in the penetrating portion are relatively heat-exchanged to the left and right side walls 46 and 45. In this way, there is no mechanical load on the penetrating portion. Thereby, the heat exchange part 4A can be prevented from being damaged.

Constructed from aluminized steel. In contrast, the rear wall 36 for the combustion chamber, the bottom wall 37 for the combustion chamber, the rear wall 48 for heat exchange, and the top wall 54 for the tube may be used as a group, and the right wall 33 for the combustion chamber and heat transfer 19 200535386 may be replaced. The right side wall 45, the right side wall 57 for the pipe, the left side wall 34 for the combustion chamber, the left side wall 46 for heat exchange and the left side wall 58 for the pipe are grouped, and the front side wall 35 for the combustion chamber, the front side wall 47 for heat exchange, and the exhaust cover 6 One set, and each set consists of one sheet of stainless steel. 5 In this way, since the constituent wall of the gas combustion chamber 34 to the exhaust pipe portion 56 is formed by a continuous sheet, the accuracy of the overall south dimension of the hot water supply can be improved. 2. In the above embodiment, the pipe top wall 54, the heat exchange rear side wall 48 and the pipe rear side wall 542 are formed by a common piece of board, but the pipe top can also be made as in the case of the eighth invention of the patent application. The wall 54 is an extension wall forming part of the exhaust port cover 6. That is, the constituent wall of the exhaust port cover 6 may be extended upward, and the extension portion may be bent toward the rear (in the direction of the pipe rear side wall 542), and the rear bent portion may be used as the pipe top wall 54.
