  Hereinafter, a preferred embodiment of the present invention will be described.

  Reference numeral 1 denotes a combustor body (combustor) having a rectangular parallelepiped (including but not limited to a cylindrical body, a square, and other shapes). In the examples of FIGS. Is composed of a wall surface 100 (wall plate), an upper upper surface 101 (top plate), and a lower bottom surface 102 (bottom plate). Desirably, the member is made of a heat-resistant metal because high-temperature combustion is intended. In addition, the combustor body 1 is preferably, for example, a canister and uses waste materials, but is not limited. The upper surface is the upper surface of the upper surface 101 (combustor body 1). An interior 1 a of the combustor body 1 is a combustion chamber 104. Further, the upper surface 101 forms a kerf 103 in the upright part 101 a, and the kerf 103 is fitted on the wall surface 100. Using this fitting structure, a second opening 105 (first suction port) is formed with the open top portion of the combustor body 1 (combustion chamber 104). The second opening 105 serves as a first intake port for the combustion chamber 104, and serves as an intake port for taking in air such as outside air. That is, the movement of the upper surface 101, for example, the movement (opening and closing) of the upper surface 101 as shown in FIGS. This is an act of selecting the size adjustment of the open area in the front and rear X and Y directions, or the opening of only one side y. For example, there is an example shown in FIGS. 4A is a plan view of FIG. 1A, and the upper surface 101 is in the rear Y, and the outside air (air) is sucked only from the second opening 105. In FIG. 4B, the upper surface 101 has moved to the front X from FIG. 4-1, but in the rear Y as in FIG. 4-1, the outside air is sucked only from the second opening 105. However, the 2nd opening 105 becomes narrow and external air suction becomes smaller compared with FIG. 4-1, for example, can reduce thermal power adjustment or the consumption of soot W. 4-3, the upper surface 101 is further moved forward X from the state of FIG. 4-2, and a sixth opening 107 is formed in the rear Y. The sixth opening 107 is combined with the second opening 105 from the sixth opening 107. It becomes the outside air suction. As a result, outside air is sucked into the combustion chamber 104 substantially evenly, and uniform combustion can be achieved. In addition, the adjustment of the second opening 105 can change, for example, the relationship between the air suction amount and the fourth opening of the combustion cylinder, which will be described later, the intake direction of the high-temperature combustion gas, the intake amount, etc. It is conceivable that the situation of secondary combustion can be changed, and that the situation of secondary combustion can be changed (the same is considered for other structures). The opening area of the second opening 105 can be adjusted by placing an obstruction such as a plate material (not shown), a kettle, or a cooking appliance. As shown in FIG. 8, there may be a structure in which the second opening 105 is provided in the wall surface 100 of the combustor body 1 (combustion chamber 104). FIG. 6 etc. are figures which put Gotoku 4 and the kettle in the opening part of the chimney 3, and are examples. Moreover, the 2nd opening 105 (1st suction inlet) serves also as supply ports, such as a soot. The upper surface 101 can be a flat plate.

  In this example, the first opening 106 (exhaust port) provided on the upper surface 101 has an octagonal end surface shape, and the combustion cylinder 2 is suspended from the first opening 106. The third opening 200 is separated from the bottom surface 102 of the combustor body 1 (becomes a suction port). Therefore, the combustion gas A generated by the combustor body 1 passes through the third opening 200 and reaches the inside 201 of the combustion cylinder 2 without receiving resistance. Note that the upper portion of the annular bulging portion 203 bulging above the combustion cylinder 2 (Z direction) protrudes from the upper surface of the upper surface 101. The annular bulge portion 203 is, for example, for hanging, and the projecting portion is for supporting the chimney 3.

  A fourth opening 202 is formed above the combustion cylinder 2 (below the narrowed cylindrical portion 2 b above the combustion chamber 104 of the combustor body 1), and the fourth opening 200 is generated by the combustor body 1. After that, the high-temperature combustion gas A1 (combustion gas rising toward the upper surface 101) that has risen in the combustion chamber 104 is taken in, and the high-temperature combustion gas A1 and the combustion gas A that has risen in the interior 201 of the combustion cylinder 2 are taken in. There is a feature that combustion (secondary combustion) of the mixed combustion gas A2 that merges with the gas can be achieved. The narrowed cylindrical portion 2 b is, for example, a location (part) above the lid 101 of the combustion cylinder 2 and a location where the chimney 3 can be attached. Further, the narrowed cylindrical portion 2b functions as a chimney.

  In the figure, reference numeral 3 denotes a chimney that is connected to the narrowed cylindrical portion 2 b of the combustion cylinder 2. 4 indicates five virtues.

  The combustion cylinder 2 has a structure in which the cylindrical portion 2a is rotatably provided in the first opening 106 of the upper surface 101, and has a fourth opening 202 in the upper part. Therefore, the aforementioned secondary combustion can be achieved. Further, by utilizing the fact that it is freely rotatable, it is possible to select from any part of the combustion chamber 104 and take in the high-temperature combustion gas A1, and / or adjust the amount of the intake. The fourth opening 202 is, for example, half as wide as the entire peripheral surface of the combustion cylinder 2. The combustion cylinder 2 can change the fitting position in the first opening 106. For example, the combustion cylinder 2 can rotate in the horizontal direction in a state where the combustion appliance is installed (for example, in a horizontal state). Using this rotation, the direction in which the fourth opening 202 faces can be freely changed. Further, by this change, adjustment of the intake amount of the gas such as the high-temperature combustion gas A1 in the combustion chamber 104 (the amount of the high-temperature combustion gas A1 that merges with the combustion gas A in the combustion cylinder 2), or the second opening The amount of air taken in from 105 can be adjusted. In addition, the amount of air taken in from the fifth opening 108 can also be adjusted.

  Further, when the combustion cylinder 2 is inserted into the first opening 106, a fifth opening 108 (a gap formed when the combustion cylinder 2 is inserted) is formed between the first opening 106 and the chimney 3. . The fifth opening 108 serves as a second intake port (second intake port). For example, the sucked air is used for cooling the narrowed cylindrical portion 2b of the combustion cylinder 2 and / or the high heat portion of the chimney 3. In addition, air can be sucked into the combustion chamber 104 (inside the chamber) of the combustor body 1 as the second intake port.

  In the example of FIG. 7, the combustor body 1 has a structure of another example in which a hole 1000 is formed in the ground. Hereinafter, as a general rule, the combustor body 1 includes a hole 1000. In this other example, the other structures are the same as those of the above-described examples of FIGS. 1 to 5-2. In this other example, the combustion state, its function, and each combustion gas, and / or The flow of air, etc., the relationship of exhaust, etc. are in accordance with the above example.

  1-1 and FIG. 1-2, the suction of outside air, the flow of internal air, the flow of combustion gas A, that is, the use of the combustion appliance will be described. The open second opening 105 is used. Then, soot W is put into the combustion chamber 104 of the combustor body 1. Ignite 薪 W. In the combustion chamber 104, the soot W burns, and high-temperature (high heat) combustion gas A (first combustion gas, high-temperature air) is generated. The combustion gas A (including unburned gas) flows (sucks) in the direction of the combustion cylinder 2 after bypassing the bottom surface 102. That is, after flowing so as to crawl over the bottom surface 102, the combustion cylinder 2 is raised after being smoothly guided into the combustion cylinder 2 through the third opening 200. The other combustion gas A is affected by the suction force generated in the combustion cylinder 2, and most of the other combustion gas A is attracted into the combustion cylinder 2 from the fourth opening 202.

  This induced combustion gas A rises in the combustion cylinder 2. In the middle of this, a negative pressure phenomenon occurs in the vicinity of the fourth opening 202 and the cylindrical portion 2 c at the upper end on the back side of the fourth opening 202. Due to this negative pressure phenomenon, the high-temperature combustion gas A1 that has been generated in the combustor body 1 and then moved up in the combustion chamber 104 is taken in. Therefore, the combustion (secondary combustion) of the mixed combustion gas A2 by the high-temperature combustion gas A1 and the combustion gas A that has risen inside the combustion cylinder 2 can be achieved. The combustion gas A3 made smokeless by this secondary combustion is discharged from the chimney 3 to the outdoors.

  In the drawings, the flow of the combustion gas A or the high-temperature combustion gas A1 is shown by arrows in FIGS. 1-2, 5-1, and the like.

  The upper surface 101 and the five virtues 4 are used for placing pots, kettles, kettles, etc., and for warming and cooking foods.

  The feature of the present invention is, in principle, the basic feature that the canister, pail can, drum can, or hole in the ground that becomes the combustor body 1 is in a sealed state, but if necessary, the combustor body It is also possible to provide an openable / closable intake port on one peripheral wall surface.
