(Example of use)
When using the stove 100, the furnace holding arm 46 and the leg main body 14 are attached to the furnace holding arm connecting part 41 and the leg base 13, respectively, and the stand 1 is assembled. And the fixing | fixed part 23 is once loosened and the height position of the combustion furnace 3 currently hold | maintained at the furnace holding part 12 and the furnace holding part 12 is changed. Then, after the furnace holding part 12 is positioned at an arbitrary height position, the fixing part 23 is tightened again to fix the furnace holding part 12 and the combustion furnace 3 at the height position. For example, when a heavy object such as a pan is placed on the combustion furnace 3, the furnace holding part 12 can be positioned low to lower the center of gravity, thereby stabilizing the stove 100. In addition, when the stove 100 is used as a bonfire or bonfire, the furnace holding part 12 can be positioned higher, thereby making it easy to visually recognize the inside of the combustion furnace 3 and expanding the range illuminated by the bonfire. In addition, fuel such as soot and charcoal can be easily charged into the combustion furnace 3. In addition, since the combustion furnace 3 can be separated from the leg portion 11, it is possible to prevent the leg portion 11 from obstructing the flow of air flowing into the combustion furnace 3.

  The furnace holding arm connecting portion 41 is arranged below the center of gravity of the combustion furnace 3, and three furnace holding arms 46 are arranged at equal intervals in the circumferential direction around the central axis C, with the central axis C as the center. Since the three leg bodies 14 are arranged at equal intervals in the circumferential direction, the stability of the stove 100 can be improved. Four or more furnace holding arms 46 and leg main bodies 14 may be provided.

  Then, the ash tray 2 is placed on the furnace holding arm 46, and the combustion furnace 3 is further placed on the ash tray 2.

  Then, for example, an ignition agent is placed on the fire bed 51 of the combustion furnace 3 to ignite, and solid fuel such as soot and charcoal is placed around the fire of the ignition agent inside the combustion furnace 3. At this time, it is possible to avoid obstructing the flow of the combustion gas by placing the elongated solid fuel in an upright state. Then, the high-temperature gas generated by the combustion of the igniting agent moves upward, thereby lowering the atmospheric pressure in the lower part of the combustion furnace 3. (Chimney effect). This makes it possible to easily ignite the solid fuel even when the solid fuel is in a state where it is difficult to burn, such as when it contains moisture. In addition, cooking, bonfire and lighting can be performed while preventing disappearance. The combustion furnace 3 is configured such that the furnace holding arm 46 holds the combustion furnace 3, and the influence on the flow of air toward the intake hole 54 can be limited, so that the intake efficiency of the combustion furnace 3 is improved. Can be made. Furthermore, the peripheral wall 52 of the combustion furnace 3 prevents crosswinds, thereby preventing ash diffusion.

  And when cooking using the stove 100, after a fire force becomes strong enough, a cooking utensil etc. are mounted on the combustion furnace 3. FIG. At this time, the opening 56 is closed, but since the exhaust hole 55 is formed in the peripheral wall 52, the combustion gas can be discharged to the outside from the exhaust hole 55, and the air flow in the combustion furnace 3 is hindered. This can be prevented. Further, when a cooking utensil or the like is placed on the combustion furnace 3, the user can easily visually recognize the inside of the furnace through the exhaust hole 55. Furthermore, fire scissors can be inserted into the exhaust hole 55 to lift the combustion furnace 3. The combustion furnace 3 may be provided with a handle for lifting the combustion furnace 3.

  In addition, since the ash receiving tray 2 is disposed under the combustion furnace 3, it is possible to prevent ash falling from the intake hole 54 from falling on the ground or the stand 1 and diffusing.

  And after using the stove 100, the furnace holding arm 46 and the leg main body 14 can be removed from the furnace holding arm connection part 41 and the leg base 13, respectively. And in the state which removed the furnace holding arm 46 and the leg main body 14, the protrusion to the radial direction centering on the central axis C can be suppressed, and it can accommodate compactly. Moreover, it is advantageous for carrying.

  From the foregoing description, many modifications and other embodiments of the present invention are apparent to persons skilled in the art. Accordingly, the foregoing description is to be construed as illustrative only and is provided for the purpose of teaching those skilled in the art the best mode of carrying out the invention. Details of the structure and / or function may be substantially changed without departing from the spirit of the present invention.
