 The combustion device of the present invention includes a pair of leg plates facing each other, a bottom plate, a pair of side plates facing each other rotatably connected to opposite sides of the bottom plate, and a heat shield plate. The leg plate and the side plate are connected so as to be rotatable around their respective upper edges, and when assembled, a combustion chamber is composed of both side plates, a bottom plate, and both leg plates. Is removably attached below the combustion chamber.

[0007] Therefore, when assembled and used, small pieces of fuel, ash, and the like burning in the combustion chamber are received by the heat shield plate. Heat rays and high-temperature airflow from the combustion chamber downward are also blocked by the heat shield plate, and the amount reaching the floor and the dining table is greatly reduced. As a result, burning and deterioration of the floor and the dining table are reduced.

Further, when storing the combustion apparatus, the detachable heat shield plate may be removed, and the leg plate, the side plate and the bottom plate may be folded together.

[0009] Another combustion device of the present invention comprises a rectangular frame member, a side plate whose upper side is rotatably attached to the first two opposing sides of the frame member, and a side plate that is rotatably mounted on the opposing two sides of the frame member. A leg plate whose upper side is rotatably attached to two orthogonal second opposing sides, a bottom plate whose two opposing sides are rotatably mounted on lower sides of the pair of side plates, respectively, and opposing below the bottom plate. A heat shield plate detachably mounted between the pair of leg plates.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a combustion device of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view of an embodiment of the combustion apparatus according to the present invention after assembly. FIG. 2 is a cross-sectional view of the combustion device of FIG. FIG. 3 is a perspective view showing a procedure for folding the combustion device of FIG.

As shown in FIGS. 1 and 2, the present combustion apparatus 1 includes a combustion chamber 2 having an open upper end, and a pair of leg plates 3 that support the combustion chamber 2 and are placed on a floor or a table. ing. The combustion chamber 2 includes a bottom plate 4, a pair of mutually opposed side plates 5 rotatably connected to opposing sides of the bottom plate 4, and one of the leg plates 3 assembled to close both ends of the both side plates 5. And a part. The leg plate 3, the side plate 5, and the bottom plate 4 are rotatably connected so as to be folded and assembled as described later. The fixing between the leg plate 3 and the combustion chamber 2 is performed by engagement between a movable engaging claw 14 provided on the leg plate 3 and a slit 15 formed near both sides of the bottom plate, as described later. The engaging claw 14 is provided so as to penetrate an elongated hole (not shown) formed in the leg plate 3 and is guided by the elongated hole. The knob 14a is located outside the leg plate 3, and the claw 14b is located inside.

Reference numeral 6 denotes a heat shielding plate, and reference numeral 7 denotes a wire net on which foods and the like are placed. Although the material of the heat shield plate 6 is not particularly limited, in the present embodiment, the heat shield plate 6 is formed in a tray shape from a stainless steel plate, and the upper surface thereof is mirror-finished. Of course, the steel plate may be subjected to chrome plating or tin plating.

The side plates 5 are assembled so as to be inclined with respect to each other so that the combustion chamber 2 becomes wider upward. That is, the width of the bottom plate 4 in the direction parallel to the leg plate 3 is smaller than the width of the leg plate 3. Therefore, a small amount of fuel can efficiently heat the object to be heated, such as foodstuffs, located thereabove over a wide range.

A plurality of locking holes 8 are formed near the lower side of the side plates 5. Slightly above the bottom plate 4 in the combustion chamber 2, a lantern (referred to as a rostor) 9 is engaged with the engaging hole 8 and mounted. Since the locking hole 8 is oval, the rostor 9 becomes detachable. A solid fuel (not shown) is placed on the roastle 9.

A large notch 10 is formed in the middle of the lower side of both leg plates 3 so that an air flow can pass therethrough. Locking shelves 11 are formed substantially parallel to the bottom plate 4 above the cutouts 10 in the two leg plates 3 and below the bottom plate 4. The locking shelf 11 has a substantially L-shaped cross section. The heat shield plate 6 is placed on the horizontal portion of the locking shelf 11 from the side, so that the locking shelf 11 is placed on both locking shelves 11. You. The leg plate 3 only needs to be plate-shaped in a portion constituting the combustion chamber 2, and the leg plate 3 may be formed in a foot-like shape below it so that it can be placed on a floor or the like. The foot portion may be formed, for example, from a steel wire.

The width of the heat shielding plate 6 in the direction parallel to the leg plate 3 is larger than the width of the bottom plate 4 and is substantially the same as the width of the leg plate 6. Therefore, even when the combustion chamber 2 is heated to a high temperature, not only radiant heat directly below the bottom plate 4 but also oblique radiant heat from the side plate 5 is reflected to prevent damage to the floor and the dining table. I do. In addition, even if small pieces of fuel or ash fall from the gap between the bottom plate 4 and the side plate 5 formed as an air passage for combustion and the gap between the bottom plate 4 and the side plate 5 and the leg plate 3, the heat shielding plate is formed. It is received by 6.

As is clear from FIG. 3 as well, both leg plates 3 and both side plates 5 are rotatable by being curved so that their upper sides are wound around a square frame member 12 made of steel wire. It is connected to. The bottom plate 4 and the side plates 5 are rotatably connected by being curved so that their sides are wound around hinge bar members 13 made of steel wires disposed on both sides of the bottom plate 4. The frame member 12 need not be a single square member. For example, four L-shaped steel wires may be arranged at the four corners of the square upper end opening of the combustion chamber, and leg plates 3 and side plates 5 may be wound around both ends of the L-shaped steel wires and rotatably connected. .

With this structure, the present combustion device 1 can be easily folded and assembled as follows.

As shown in FIG. 3A, after the heat shield plate 6 is extracted from the combustion device 1 in the state shown in FIG. 1, the knobs 14 a of the engaging claws 14 of the two leg plates 3 are slid upward. 4, the claw portion 14 b is pulled out from the slit 15 to release the fixing between the leg plate 3 and the bottom plate 4. As a result, both leg plates 3 can be rotated upward. Remove Rostor 9 before or after that.

Next, as shown in FIG. 3B, the both side plates 5 are rotated with respect to the frame member 12 and the bottom plate 4 to be folded as shown. Then, although not shown, the both leg plates 3 are further rotated to overlap the folded side plate 5 and the bottom plate 4. If the wire netting 7, the heat shielding plate 6 and the rostral 9 are superimposed thereon, the storage becomes easy.

When assembling, an operation reverse to the above may be performed. That is, the both leg plates 3 are opened, and the both side plates 5 and the bottom plate 4 are in the form shown in FIG. Then, both leg plates 3 are further rotated to abut both sides of side plate 5 and bottom plate 4. Then, the hook 14b is inserted into the slit 15 of the bottom plate 4 by lowering the engaging hook 14 downward. After that, the roaster 9 is attached and the wire mesh 7 is placed.

In the present combustion apparatus 1, if a gap 16 (FIG. 3) is formed between the bottom plate 4 and the side plates 5, the air for combustion together with the locking holes 8 for the rostles 9 is formed. Holes are provided. It is also possible to form an air hole 17 near the upper side of both side plates 5 as shown.

According to the combustion apparatus 1 configured as described above, even if the small pieces and ash of the fuel filled and burned on the roaster 9 drop from the above-mentioned gap 16 or the like, the heat shielding plate 6 causes the combustion. The radiant heat from the combustion chamber 2 is received and reflected upward by the heat shield plate 6. Since there is a notch formed between the two leg plates and below the leg plate 3 below the heat shielding plate 6, the cooling is effectively performed by the airflow passing therethrough.
