The combustion section 40 is formed of an outer box 41 made of heat-resistant steel (heat-resistant 400°C) and an inner box 42 made of special heat-resistant stainless steel (heat-resistant 700°C). Cooling air (arrow indicated by a dashed line) flows through the air intake port 73a of the mounting member 73 and the through hole 60 of the pedestal 60.
b, the outer box 4 through the through holes 41c of the outer box 41, respectively.
1 and the inner box 42, the outer box 41
, the inner box 42 and the draft tubes 52a, 52b are cooled by the cooling air and can sufficiently withstand the heat of the combustion flame ejected from the burners 80a, 80b.

ａ，９２ｂの冷却機能が低下することがない。FIG. 3 shows a second embodiment of the present invention, in which a through hole 41d and an air passage 91a are formed on one side of the lower part of a blower duct 91 of a blower 90 that supplies combustion air and on one side of the lower part of the outer box 41. This is a water heater in which the combustion air is circulated through the gap between the outer box 41 and the inner box 42. Since this embodiment has such a configuration, the outer box 41, the inner box 42, and the trough tubes 92a and 92b can be cooled by the combustion air from the blower 90 (indicated by the arrow shown by the one-dot chain line), and the cooling air can be supplied separately. Since it is not necessary to provide a dedicated air blower 70, the cost is low. Moreover, even if a head wind comes in from the exhaust pipe 32 of the water heater main body 20, the blower 90 is large (
Since the pressure is 28 to 35 mmAg), the wind does not stagnate, and the outer box 41, inner box 42, and draft tube 92
The cooling functions of a and 92b do not deteriorate.

The upper plate of the pedestal 110 and the bottom plate of the outer box 41 are communicated through the through holes 41e and 110b, and the combustion air is communicated between the outer box 41 and the inner box. This is a water heater that circulates water through the gap between the water heater and the water heater. Also in this embodiment, the outer box 41, the inner box 42, and the draft tubes 102a and 102b can be cooled.

It consists of a box and an inner box made of special heat-resistant steel with a predetermined gap between them, and is equipped with a cooling air supply blower to blow cooling air into the gap, so the outer box of the heat exchange section is heat-resistant. The inner box is made of special heat-resistant steel, and the outer box and inner box are cooled by cooling air blown by a cooling air supply blower, so they can withstand the combustion heat of liquid fuel. can. In addition, since it does not use the expensive and water-resistant ceramic fibers that have traditionally been used as heat-resistant materials, it is cheaper in terms of cost, and there is no risk of damage even if condensation forms inside the combustion part. That's not it. Furthermore, since the cooling air that has become high temperature after flowing through the gap flows from the opening on the heat exchange section side of the combustion section to the heat exchange section, heat exchange is also performed by the cooling air, and the heat exchange function is performed. It has the advantage of not impairing the

に割安であるという利点等を有する。A second invention is a water heater that includes a water heater main body in which a heat exchange part and a combustion part that burns liquid fuel are connected to each other, and a blower that supplies combustion air to the combustion part. Each section consists of an outer box made of heat-resistant steel that is open on the side of the heat exchange section, and an inner box made of special heat-resistant steel that is spaced apart from the outer box by a predetermined distance. Since an air passage is provided that blows a part of the air as cooling air, not only the effect of the first invention can be obtained, but also the outer box and the inner box can be cooled by the combustion air blower, so they can be cooled separately. It has the advantage of not requiring an air supply blower and being inexpensive.
