く、コストを上昇させる欠点があった。(c) Problems to be Solved by the Invention In the conventional water heater mentioned above, the resistance in the exhaust passage is low, so when the burner burns strongly, the combustion balance is disturbed, causing oscillating combustion, which increases combustion noise. was there. Therefore, in recent years, a perforated plate with many small diameter holes has been installed at the exhaust port of the exhaust passage to increase the pressure in the combustion chamber and prevent vibrational combustion, thereby reducing combustion noise. However, with this type, both a drain plate and a perforated plate must be installed at the exhaust port in a narrow space, so the shape has to be complicated due to space constraints, and the assembly work is difficult. There were drawbacks that not only made things worse, but also increased costs.
