た。Configuration and problems of conventional examples In conventional hot-air heaters in which multiple heat exchange pipes are connected to the combustion cylinder via connectors, the flow rate of combustion gas flowing through each heat exchange pipe is almost equal. Because of the heat, the fuel exchange on the downstream side of the heat exchange pipe located on the upstream side of the ventilation passage is poor, which not only leads to a loss of thermal efficiency of the entire device, but also that the heat exchange pipe located on the downstream side of the ventilation passage has a There were problems in that it was prone to deterioration due to rising temperatures and trapping of heat, and that expensive materials had to be used.

スの温度が下がるのである。DESCRIPTION OF EMBODIMENTS FIG. 1 is a diagram showing the inside of a warm air heater according to an embodiment of the present invention, and FIG. 2 is a left side diagram of the same. In the figure, combustion gas generated in a burner 1 passes through a combustion chamber in a cylindrical combustion tube 2, a connector 3, a plurality of cylindrical heat exchange pipes 4, an exhaust header 5, and an exhaust pipe 6, and is exhausted to the outside. Ru. At this time, heat is exchanged with the air from the convection fan 7 in the combustion tube 2, the connecting body 3, and the heat exchange pipe 4, and it is released into the room as warm air from the outlet A.
Used for hot air heating. Note that the arrows in FIG. 2 indicate the flow of air by the convection fan 7. Figures 3 and 4 show the connecting body 3 of this warm air heater, and this connecting body 3 has a heat-resistant packing 9 sandwiched between a plate-shaped header 8 fixed to the combustion tube 2 and the heat exchange pipe 4. The seal fixing plate 10 and the lid 11 are covered with each other. From the header 8 to the lid 1 on the packing fixing plate 10
1, a bent portion 10a is provided with a height h2 lower than the drawing depth h1 of the lid. This prevents the short-circuited flow of combustion gas as shown by the dashed arrow in Figures 3 and 4, and allows it to flow in a detour as shown by the solid arrow.
Heat exchange on one side is improved and the temperature of the combustion gas flowing into the heat exchange pipe 4 is lowered. In other words, if there is no bent portion 10a, the combustion gas that flows away from the side surface of the lid 11 as indicated by the broken line arrow does not come into contact with the side surface of the lid 11, and therefore flows directly to the heat exchange pipe 4 without undergoing heat exchange. Part 1
When 0a is provided, most of the combustion gas flows as shown by the solid line arrow, comes into contact with the side surface of the lid 11, and exchanges heat with the air from the convection fan 7 flowing outside the side surface of the lid 11. Therefore, the heat exchange efficiency improves, and the temperature of the combustion gas flowing into the heat exchange pipe 4 decreases accordingly.
また上記折り曲げ部１０ａはパツキン固定板１

強度は向上し、高温ガスによりパツキン固定板１
０がひずむのを防止するようにもなる。 Further, the bent portion 10a is the packing fixing plate 1.
Since it is bent so as to be substantially orthogonal to the plane part 0, the strength of the packing fixing plate 10 is greatly improved compared to a simple plane part. Therefore, the strength against thermal deformation of the gasket fixing plate 10 is improved accordingly, and the gasket fixing plate 1 is
It also prevents 0 from being distorted.

A plurality of holes 10b having a diameter equal to or less than the inner diameter of the heat exchange pipe 4 are bored at positions facing the heat exchange pipe 4. this hole 1
The diameter of the hole 0b becomes larger as the distance from the combustion tube 2 increases, that is, the downstream side of the combustion gas (upstream side of the convective air). By doing this, the heat exchange pipe 4 with higher heat exchange efficiency on the upstream side of the convective air can flow a large amount of combustion gas, which not only increases the heat exchange rate of the equipment as a whole, but also increases the heat exchange efficiency of the header 8. The temperature can be lowered than in the conventional method and the temperature distribution can be made uniform. Therefore, there is an advantage that it is not necessary to use expensive materials for the header 8 as in the conventional case.

化にも大きな効果がある。Effects of the Invention As described above, the present invention employs a simple structure in which the combustion cylinder side of the gasket fixing plate in the coupling body is bent and the holes are provided with different diameters, thereby increasing thermal efficiency. In addition to preventing thermal deterioration of the gasket, there is no problem of poor airtightness and exhaust gas leakage due to deformation of the gasket fixing plate, and pipes with different diameters such as heat exchange pipes with different diameters are avoided. This also has a great effect on simplifying the configuration and parts management, as it eliminates the need to prepare multiple types of components to complicate the configuration and parts management.
