It is a side view of the form example of FIG.

Hereinafter, a morphological example of the polygonal (pentagonal) combustion device according to the present invention will be described in detail with reference to the accompanying drawings (FIGS. 1 to 8). As a basic form, this combustion device includes a top plate 15 having a polygonal flat shape so that a flat shape capable of burning firewood forms a polygonal combustion chamber 10. The polygon may be a substantial shape, and the bent portion or the corner portion 16 has a chamfered or rounded shape, or the side wall portion 12 of the main body 11 is partially curved. It also includes a morphology, which means a morphology in which corners are substantially formed to form a polygon.

A perforated bottom plate portion 22 formed by a perforated plate is provided so as to form the bottom portion of the space, and is provided so as to promote combustion by being overheated. The shape of the perforated bottom plate portion 22 of this embodiment is a pentagon similar to that of the pentagonal top plate 15, and the perforated side plate portion 21 corresponds to three of the five surfaces of the pentagonal cylinder. However, the shape is not limited to this as long as the secondary combustion chamber can be appropriately partitioned, and may be, for example, an arc shape.

Further, reference numeral 30 denotes a tubular combustion promoting member, which is extended in a cylindrical shape upward from the upper surface of the perforated bottom plate portion 22 so as to leave a gap inside the chimney opening 17 from the inner peripheral surface of the chimney opening 17. It is provided so as to be arranged concentrically so as to be perforated and formed in a cylindrical shape to promote combustion by being overheated. Since the space is provided by a ring-shaped gap between the chimney opening 17 and the tubular combustion promoting member 30, the heat that heats the tubular combustion promoting member 30 does not easily escape to the main body 11 side.

Become. Further, even in the tubular combustion promoting member 30, combustion is promoted as an ignition source by being overheated to a high temperature while being properly performed in a state where the air flow is rectified due to the large number of through holes. In addition, since they are arranged concentrically with the chimney opening 17, the combustion air is rectified even in the relationship between the chimney opening 17 and the corner compartment combustion promoting member 20 surrounding the periphery on the lower side. At the same time, the exhaust flow velocity of the exhaust can be increased by the draft effect (chimney effect) due to the updraft of the combustion air, and the effect of appropriately promoting the flow of fresh combustion air to be sucked and supplied and improving the combustion efficiency. There is.
