Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention belongs to the field of stoves that utilize radiant heat effectively.

``Conventional technology'' Traditionally, wood-fired stoves used in homes use ash on the inner bottom of the combustion chamber to insulate the bottom of the combustion chamber, resulting in low heat radiation from the bottom of the combustion chamber. The drawback was that most of the heat was discharged to the outside air along with the exhaust smoke, making it difficult to effectively utilize the combustion heat.

``Problem to be solved by the invention'' The problem to be solved by the present invention is to separate the combustion chamber and the ash box below it, make the bottom of the combustion chamber a heat radiating surface, and further radiate heat between the side walls of the combustion chamber. The purpose is to expand the heat radiating area by providing a through-hole section and using the section as a heat radiating surface.

"Means for Solving the Problems" The means taken by the present invention to solve the above problems are as follows: The combustion heat of combustion chamber a is radiated from the bottom plate by a communication pipe for removing ash at a vertical interval, and the upper corner of the rear smoke exhaust part of combustion chamber a is connected to both side walls of the combustion chamber. An L-shaped hollow box is partitioned in between to form the exhaust heat diffusion section c, and the vertical part of the partition has heat radiation holes that circulate outside air to both side walls of the combustion chamber, and the horizontal part has the same heat dissipation holes. A heat radiation hole for outside air circulation is provided through the combustion chamber, and a smoke exhaust pipe is provided horizontally in the vertical portion leading from the combustion chamber a to the chimney, and a heat radiation hole is provided in the ceiling of the combustion chamber in the upper part of the vertical portion, leading to the vertical portion. A flue is provided between the front end of the horizontal part and the rear wall of the exhaust heat diffusion part c.

"Operation" According to the above means, the radiant heat from the bottom of the combustion chamber is diffused from the space to the surroundings, and the radiant heat from both surfaces of the partition is radiated to the surroundings from the heat radiation holes.

``Embodiment'' An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 3, the combustion chamber a has a longitudinal cross section with the smoke exhaust section on the rear side being semicircular in plan view. It consists of a rectangular box body, and as shown in Figure 2, a fuel injection door 1 is attached to the front, a handle 2, a peephole 3, and an air intake door 4 are attached to the door 1, and an assembly is attached to the top panel. A ring 6 is provided, and legs 8 are provided on the front, rear, left and right sides of the bottom board 7. The ash-catching box b consists of a box body that has approximately the same area as the bottom plate 7 in plan view and has a horizontally long rectangular cross section.The main body is fixed between the legs 8 on both sides, houses the drawer 9 that can be moved in and out, and has a top plate. A communication pipe 11 for dropping combustion ash, which is erected in the center of the casing 10, is connected to the bottom plate 7, and a rostol 12 is locked in the communication pipe 11. Thus, a combustion heat radiation space 13 is formed between the bottom plate 7 and the top plate 10. Next, on the rear side of the combustion chamber a, the lower part of the canopy that includes the chimney 5, that is, the upper corner of the smoke exhaust part, is cut out to allow a detachable exhaust heat diffusion part c that does not change the external shape of the combustion chamber a. are fitted to prevent smoke leakage. The portion c is provided with an L-shaped hollow box-shaped partition portion 16 that partitions the portion c into an L-shape between both side walls (front and rear walls in FIG. 1). In the same part 16, a heat radiation hole 18 is provided in the vertical part of the partition part 16, and a heat radiation hole 21 is provided in the horizontal part of the partition part 16, so that the outside air can flow between the both sides walls of the exhaust heat diffusion part c. Further, a heat radiation hole 17 is provided through the canopy of the combustion chamber a in communication with the canopy of the combustion chamber a. Then, a smoke exhaust pipe 14 is installed horizontally through the vertical part of the partition part 16 so that smoke is exhausted from the combustion chamber a to the chimney 5, and the smoke exhaust pipe 1
The shielding plate 1 is configured to increase the heat dissipation surface area by narrowing the periphery of the shielding plate 1 to form a flue 15 between the front end of the horizontal part of the partition part 16 and the rear wall of the exhaust heat diffusion part c, and to open and close the flue 15.
9 can be operated from the outside with a knob 20.

The one shown in FIG. 6 is another embodiment of the present invention, in which the bottom plate 7 of the combustion chamber a is a funnel-shaped inclined wall, and the top plate 10 of the ash collecting box b is formed horizontally, and both are connected to a communicating pipe 11. , and a radiation space 13 is formed between the two. In addition, the radiant space 13 can be formed in such a way that the top plate 10 is in the shape of an inverted funnel and the bottom plate 7 is horizontal, or the top plate 10 and the bottom plate 7 have a semicylindrical cross section. In the embodiment, the exhaust heat diffusion part c is fitted into the combustion chamber a for convenience in manufacturing.

"Effects of the Invention" According to the present invention, the heat radiation effect is extremely large due to the radiant heat from the bottom surface of the combustion chamber a and the exhaust heat diffusion from the partition section.
