Description

  TECHNICAL FIELD The present invention relates to a bonfire that can easily ignite using natural fuel such as fallen leaves and dead trees, and more particularly to a bonfire that is convenient to carry and has excellent combustion performance and does not disappear.

  Cassette gas stoves and charcoal stoves are often used as camping equipment for cooking barbecue and hot pot dishes outdoors. These can provide the thermal power required for various cookings at various scales by appropriately selecting the type and size thereof. In addition, many things can be folded compactly so that they can be easily carried in a car or the like.

  For example, Patent Document 1 describes an example of a portable stove that can be folded compactly. As shown in FIG. 7, the portable stove 110 described in Patent Document 1 has a configuration in which assembly and disassembly can be repeatedly performed by combining a plurality of metal plate materials.

  The portable stove 110 includes an ash receiving portion 120 that has a grate 130 on its upper surface and is formed in a substantially rectangular dish shape, and a surrounding plate that is provided on the upper peripheral edge of the ash receiving portion 120. The grate 130 includes a plurality of grate holes 135. The surrounding plate is configured by combining the front plate 161, the back plate 162, and the side plates 163 and 164, and is formed so as to surround the grate 130. And the inside of this surrounding board forms the combustion chamber which burns a fuel.

  The front plate 161 and the back plate 162 are assembled by being inserted between the side plates 163 and 164. Therefore, when disassembling, the front plate 161 and the back plate 162 can be pulled out from between the side plates 163 and 164 and removed. Further, the pair of side plates 163 and 164 are respectively connected to both ends of the ash receiving portion 120 by rotating shafts 121 and 122, are formed to be rotatable with respect to the ash receiving portion 120, and can be folded. .

  The portable stove 110 configured as described above can be folded compactly and stored in a car or the like when not in use. In use, fuel such as charcoal can be burned on the grate 130 by being assembled in the state shown in FIG. And cooking, such as a barbecue and a pot dish, can be performed.

  However, since such conventional portable stoves are manufactured as camping equipment, many of them are fuel-specific. That is, in many cases, the fuel used is kerosene, charcoal, cassette gas, etc., and natural fuels such as fallen leaves and dead trees cannot be used. Even when the fallen leaves, dead trees, and the like are burned using the portable stove 110 shown in FIG. 7, they often disappear due to their low combustion efficiency.

  If fallen leaves and dead trees can be burned with excellent combustion efficiency, camping life can be made more enjoyable and more economical. Even when a natural disaster is encountered, if such natural fuel can be used, it is possible to boil hot water or to cook without worrying about the presence or absence of fuel.

Legs can be opened in a slightly opened state rather than vertically. Thereby, the ash receiving part 20 can be positioned away from the ground by the length of the leg parts 41 and 42.

  FIG. 4 shows a state in which the legs 41 and 42 are opened and the side plates 63 and 64 are erected substantially vertically. On both sides of the side plate 63, slits 73, 73 opened upward are formed, and on both sides of the side plate 64, slits 74, 74 opened upward are formed. Then, slits 71, 71 opened downward are formed on both sides of the front plate 61, and slits 72, 72 opened downward are formed on both sides of the back plate 62.

  The slits 71 and 71 of the front plate 61 are formed so as to mesh with the slit 73 of the side plate 63 and the slit 74 of the side plate 64, respectively. Therefore, one slit 71 of the front plate 61 and the slit 73 of the side plate 63 are fitted so as to be inserted into each other, and the other slit 71 of the front plate 61 and the slit 74 of the side plate 64 are fitted to each other, The front plate 61 can be fixed between the two side plates 63 and 64.

  Further, the slits 72 and 72 of the back plate 62 are formed so as to mesh with the slit 73 of the side plate 63 and the slit 74 of the side plate 64, respectively. Therefore, one slit 72 of the back plate 62 and the slit 73 of the side plate 63 are fitted so as to be inserted into each other, and the other slit 72 of the back plate 62 and the slit 74 of the side plate 64 are fitted so as to be inserted into each other, The back plate 62 can be fixed between the two side plates 63 and 64.

  In this way, the front plate 61, the back plate 62, and the side plates 63 and 64 can be assembled so as to surround the upper peripheral edge of the ash receiving portion 20 to form a surrounding plate. A combustion chamber for burning the fallen leaves and dead trees is formed inside the surrounding plate composed of the front plate 61, the back plate 62, and the side plates 63 and 64.

  FIG. 5 shows a procedure for attaching the grate 31 and 32, the five victories 81 and 82, and the door 91. The grate 31 and 32 is formed in substantially the same shape and can be placed on the ash receiving portion 20. The virtues 81 and 82 can be appropriately arranged on top of the front plate 61, the back plate 62, and the side plates 63 and 64. A door 91 having a knob 99 can be attached to the front plate 61.

  The grate 31 and 32 includes a plurality of grate holes 51 and 53. As shown in FIG. 6, the grate hole 51 is an ordinary hole formed in a flat plate. Further, the grate hole 53 is formed such that the periphery thereof is raised upward by embossing. Here, an example in which the grate holes 51 and the grate holes 53 are alternately arranged vertically and horizontally is shown, but any arrangement may be used as long as the grate holes 31 and 32 are substantially equal. Is possible.

  When alternately arranged vertically and horizontally, the hole diameter of the embossed grate hole 53 is preferably slightly smaller than the hole diameter of the normally opened grate hole 51. Alternatively, it is preferable that the entire area of the embossed grate hole 53 is slightly smaller than the total area of the grate hole 51 that is normally opened. By forming in this way, fallen leaves, dead trees, etc. can be burned in a good combustion state.

  At the peripheral edge portions of the grate 31 and 32, an end side portion 35 formed by bending downward is provided. The height of the end side portion 35 forms a predetermined distance between the upper surfaces of the grate 31 and 32 and the ash receiving portion 20. A plurality of air holes 55 are provided in the end side portion 35, and outside air can be introduced below the grate 31 and 32. A plurality of air holes 25 are also provided around the ash receiving portion 20. Therefore, outside air passes through the air holes 25 and 55, is introduced to the lower side of the grate 31 and 32, and flows into the combustion chamber from the grate holes 51 and 53.

  The surrounding plate is also provided with air holes. That is, the front plate 61 is provided with a plurality of air holes 75, the back plate 62 is provided with a plurality of air holes 76, and the side plates 63 and 64 are provided with a plurality of air holes 77 and 78. Accordingly, a large amount of outside air is also introduced into the combustion chamber from the air holes 75, 76, 77, 78.

  Thus, fallen leaves, dead trees, and the like are burned by the outside air introduced from the grate holes 51, 53 and the air holes 75, 76, 77, 78 provided in the surrounding plate. Here, the embossed grate hole 53 acts very well on the introduction of outside air and promotes the burning of fallen leaves and dead trees in the lowest layer in the combustion chamber. And since a favorable convection is generated in the whole combustion chamber and the outstanding combustion efficiency is obtained, it does not cause disappearance.

  The virtues 81 and 82 are provided with slits 85 opened downward. And the slit 65 opened upwards is provided also in the upper part of the front plate 61, the back plate 62, and the side plates 63 and 64. Then, by fitting the slits 85 of the virtues 81 and 82 and the slits 65 provided on the enclosure plate so as to be inserted into each other, the virtues 81 and 82 can be attached to the upper portion of the enclosure plate.
