Description of the invention: [Technical field to which the invention belongs] TECHNICAL FIELD This Meming is related to the dimensional accuracy of the assembly of a kind of gas heating chamber and a hot water supplier. Hot water deer supply. [Prior Art] FIG. 5 is an exploded perspective view of the internal structure of a conventional hot water supply. 10 15 20 The burner member 2 composed of a plurality of flat burners 21 and 21 arranged in parallel is housed in a rectangular combustion box 3, and the upper half of the opening 30 at the front end of the combustion box 3 uses a front plate 32 Block it. In addition, in the above burner member 2 towels, gas points @ & || On the other hand, the heat exchanger 4 connected to the opening 31 located at the upper end of the combustion box 3 is a rectangular cylindrical casing 4G penetrating vertically; most of the heat absorbing sheets 4 arranged side by side in the casing transform and penetrate the heat absorption. The plate 4b 41 and the water pipe 42, 42 of the outer shell 40 are composed of the center S2 and 42, and this is shown in the figure). W 働 or the downstream end is connected with a copper pipe (the slot h is not formed on the outer casing 40, and the flange 4GA is extended, and when the flange 3 is formed, the connection between the two and the combined heat exchanger 4 and the upper edge of the combustor 3's caulking gasket 'and stand upright in the aforementioned combustor slots SI, S1. S2 and S2 are inserted in a slightly curved state as described above. 5 200533866 Combustion tank 3 (refer to Figures 5 and 6). The exhaust pipe body 5 connected to the opening 43 at the upper end of the heat exchanger 4 is formed in a rectangular box shape that is open below and above, and the aforementioned row The outer peripheral flange 53 of the lower end opening 52 of the trachea body 5 is provided with a sagging = 5 caulking tongues S3, S3. The caulking tongues S3, S3 are crimped to prevent heat exchange The outer peripheral flange 44 of the upper end of the heater 4. The hot water supply device composed of the assembly of the combustion tank 3, the heat exchanger 4, and the exhaust pipe body 5 connected in this way is suitably arranged and fixed by a bracket or the like. On the casing 9. 10 The exhaust port cover 6 is fixed downstream of the exhaust pipe body 5 by screws b, b. At the end of the exhaust port 51, an exhaust tube 60 protruding from the exhaust port cover 6 is inserted into the exhaust window 91 of the front cover 90 provided in front of the hot water supply housing 9 with ample margin. Patent Literature 1: Japanese Patent Application Laid-Open No. 2003-21319 (Figure 1) 15 [Summary of the Invention] [Disclosure of Invention] (Problems to be Solved by the Invention) However, in the conventional hot water supplier, the combustion tank 3 and heat exchange The device 4 is composed of independent parts, so it is easy to have different dimensions in the vertical and horizontal directions during assembly, and the accuracy of the height dimension of the connected body of the combustion box 3 and the heat exchanger 4 will also become inaccurate. In addition, because the connecting part of the combustion box 3 and the heat exchanger 4 is provided with a gasket to ensure air tightness, it may also cause different dimensions during assembly. The combustion box 3 and the heat exchanger The accuracy of the height dimension of the connection body of 4 will become worse. 6 200533866 This result makes the following problems among the above-mentioned people. 1. The upstream end 42 of the water-passing pipe 42 installed at the heat exchanger 4 〇The height of the configuration will increase, which will hinder the copper pipe. Wait until the pipe connection operation smoothly connected to the upstream end 420. 5 2. The height position of the exhaust port cover 6 of the exhaust pipe body $ connected to the upper end of the heat exchanger 4 and the exhaust window of the casing 9 91 is liable to form a vertical displacement. As a result, the apparatus can cause the exhaust pipe 60 of the exhaust port cover 6 and the exhaust window 91 of the casing 9 to be unable to smoothly fit during assembly. The present invention is based on the The inventors of the above-mentioned various problems are the "one of 10 kinds of hot water suppliers, in which a gas combustion chamber, a heat exchange section and an exhaust pipe section are sequentially arranged from the bottom of the casing, and the gas combustion The chamber is surrounded by four side walls of the right side wall for the combustion chamber, the left side wall for the combustion chamber, the front side wall for the combustion chamber, and the rear side wall for the combustion chamber, and is a space that houses the burner member 2 and opens upward. The heat exchange section is composed of a plurality of heat absorbing sheets 4 and 41, and water passing pipes 42 and 42 penetrating the suction sheet 4 and 4 !, and the heat absorbing sheet 41 is arranged on the right side wall for heat exchange and for heat exchange. 4 side walls of left side wall, front side wall for heat exchange and rear side wall for heat exchange In the enclosed rectangular space, ”by reducing the height of the connecting body between the combustion chamber and the heat exchange section by 20 degrees, the copper pipe piping at the upstream end 42 of the water pipe 42 can be operated or connected. The fitting of the exhaust pipe 60 provided in the exhaust port cover 6 of the exhaust pipe section and the exhaust window 91 on the housing 9 side smoothly progresses smoothly. [Method to solve the problem] [Invention of the first scope of the patent application] 7 200533866 The technical method of the invention of the first scope of the patent application to solve the above problem: "The right side wall for the combustion chamber and the right side for the heat exchange" The wall is a group-the left side wall for the combustion chamber and the left side wall for the heat exchange are one set, the rear side wall for the thermal combustion chamber and the rear side wall for the heat exchange are five groups, and the front side wall for the thermal combustion chamber The front side wall for heat exchange is a group, and each group is composed of a board. With the above-mentioned technology, among the constituent walls of the gas combustion chamber and the heat exchange section, the constituent wall systems connected up and down are each composed of a plate. Therefore, the gas combustion chamber and the heat exchange unit that are separated from each other by a virtual combination are different from the aforementioned ones, and the height dimension of the entire joint between the gas combustion chamber and the heat exchange unit can be reduced due to assembly errors. Happening. [Invention No. 2 in the scope of patent application] In the invention No. 1 in the scope of patent application, "each of the aforementioned plates can be made of the same material. 『15 If each board is made of other materials with different thermal expansion coefficients, each board heated by the combustion of gas will generate different amounts of heat in the up and down direction. As a result, the connecting portion of each of the above-mentioned plates will generate a great thermal stress, which makes the connecting portion prone to long-term decipherment. In view of this situation, in the above invention of the second item of the patent claim, since each of the sheets is made of the same material with the same thermal expansion ratio, each of the sheets will thermally expand at the same rate when the gas is burned. That is, no thermal stress is caused on the connecting portion. Therefore, k need not worry about the long-term damage of the connection portion. [Invention No. 3 in the scope of patent application] 8 200533866 In the invention No. 2 in the scope of patent application No. 2 of the invention, "the group consisting of the right side wall for the miscellaneous chamber and the right side wall for the heat exchange mentioned above, and The plates of each group of the left wall and the left wall for heat exchange are made of stainless steel, and the water passing pipes 42 and 42 penetrate the heat exchange 5: the right wall and the left wall for heat exchange, and the water pipe "42, 42 and the month" describes that the heat sinks 41 and 41 are made of a copper material, and that the through portions of the water pipes 42 and 42 are connected to the heat sink 仏 41 by brazing. 』In the Lai Lai water supplier, since the right and left plates of the right-hand wall for heat exchange and the left-hand soil for heat exchange are made of stainless steel, the mechanical strength can be improved compared with the use of copper for 10 days ^. Therefore, it is possible to reduce the damage to the hot water supply device when it is subjected to shock during shipment or installation. Further, since the sheet is made of a stainless steel material, it can improve heat resistance and suppress long-term deterioration compared to a copper material. Moreover, in the invention of the third item of the patent application, because the through-holes f of the water pipes 42, 15 and 42 are not fixed to the right-side wall constituting the heat exchange and the left-side wall replaced by the heat exchange, each piece is described. On the board, even if the water passing pipes 42 and 42 are repeatedly thermally expanded and contracted in the long direction, the thermal stress will not be generated in the aforementioned penetration portion, and there is less need to worry about the heat exchange portion being damaged. That is, although the heat absorbing sheets 41 and 41 water pipes 42 and 20 42 made of a copper material are connected to each other by brazing, the heat absorbing sheets μ and 41 through water g 42 and 42 are generally as follows Brazing using a heating furnace. That is, the 'water-passing pipes 42, 42 pass through the heat-absorbing sheet groups 41, 41, and a brazing material is appropriately interposed between the outer edges of the water-passing pipes 42, 42 and the boundary between the heat-absorbing sheets 41 and 41 at the through portion. In addition, a plate (constructed of stainless steel) that constitutes the right-hand wall for heat exchange and heat exchange 200533866 is replaced by the left and right sides i (through stainless steel) and penetrates both ends of the water pipes 42 and 42 in this state. The assembly of No. 42 and No. 4 and No. 41 and No. 41 is heated in a heating furnace to melt the aforementioned brazing material. By the fusion of the brazing material, the heat absorbing sheets 41, 41 and the water passing holes 5, 42 and 42 'are brazed by welding, but because the above-mentioned left and right plates are made of stainless steel, there is a hard: tp material flows into the piece The through portions of the through-pipes M and 42 of the board, the one board and the through-pipes 42 and 42 are not substantially connected by brazing. The reason is that the brazing material can connect the endothermic material made of copper material, {41, 41, and the water passers 42, 42, but it cannot actually connect the left and right one 10 plates made of stainless steel and the water pass pipes 42, 42. Therefore, when the above-mentioned water pipes 42 and 42 repeatedly undergo thermal expansion and contraction in the length direction with the combustion and flameout of gas, the water passing through the through portion is relatively slid with a plate, so there is no excessive force. Acts on the penetrating portion. In this way, it is possible to prevent the heat exchange unit from breaking [invention No. 4 in the scope of patent application]-Among the inventions No. 1 to 3 in the scope of patent application, "the group that constitutes the aforementioned combustion and the heat father is replaced with the right wall, The left side of the combustion chamber is replaced by the left side wall group, and the plates of each group of the rear side wall of the combustion chamber and the heat exchange_rear wall group are completely crimped to each other in the peripheral direction. Stitching connection.
