Description

[Technical field]

[0001] The present invention relates to a combustion promoter for a wood stove that can efficiently burn solid fuel such as firewood inside the furnace of a wood stove. [Background technology]

[0002] A combustion promoter used in a wood stove used indoors or outdoors is placed under the firewood when the firewood is ignited and burned, supporting the firewood while forming gaps between the firewood and between the firewood and the floor of the furnace, improving air circulation and promoting combustion. An example of a conventional technology for such a firewood stove combustion promoter is shown in Patent Document 1. This conventional technology firewood stove combustion promoter comprises a plate-shaped member and a number of protrusions that protrude from the plate-shaped member and have through holes therein along the protruding direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6032653 Summary of the Invention [Problem to be solved by the invention]

[0004] When using the combustion promoter of the prior art of Patent Document 1, the combustion promoter is placed on the floor inside the wood stove, and the firewood, which is a solid combustion material, is placed on it, but one of the openings of the through hole is blocked by the floor, which causes poor air circulation and reduces combustion efficiency. Also, since the protrusions are only provided on one side of the plate-shaped member, depending on how the firewood is placed, there is a problem that the air circulation is not good and it is difficult to promote the combustion of the firewood. [Means for solving the problem]

[0006] The present invention has been made in consideration of the above circumstances, and the means for achieving this are To the department hollow part At least two surfaces are hollow partThe adjacent polyhedrons are connected to each other through the openings of the adjacent polyhedrons. hollow part Connect and fix them together so that they communicate with each other. The six polyhedrons are arranged in a cross shape in a mutually connected state, and the openings face each other to form a connected space, and the hollows of the six polyhedrons are connected to each other through the connected space, and all the openings are connected to each other through the hollow spaces. It is used as a combustion promoter for wood stoves.

[0007] Furthermore, the polyhedron is made of a metal material, the polyhedron is made of a flammable material, and the polyhedron is a rectangular parallelepiped. Effect of the Invention

[0008] The combustion promoter for the wood stove of the present invention is a polyhedron, so when it is placed on the floor of the furnace of the wood stove during use, the edge and ridge parts are always at a certain height from the floor. When fuel such as firewood is placed on the edge and ridge parts, air circulation improves and combustion is accelerated. When multiple combustion promoters are placed, multiple edge and ridge parts are present, so a large number of firewood fuels can be stably placed across the edge and ridge parts. When firewood is ignited from below on flammable paper, a gap of the height of the polyhedron is created between the bottom of the firewood and the floor, and since the inside of the polyhedron has a hollow part, the supply of oxygen is promoted by the rising air current generated by the combustion from the opening through this hollow part, and the firewood burns well. This accelerates the temperature rise in the room. Since the opening is provided on at least two sides of the polyhedron, the rising air current flows smoothly through the hollow part and the opening, further promoting combustion.

[0009] If the above-mentioned polyhedral combustion promoters are connected and fixed so that the cavities of the combustion promoters communicate with each other through the openings of the adjacent combustion promoters to form a composite combustion promoter, it is not necessary to place them one by one on the floor surface at appropriate intervals, and they can be lined up in one placement, making the placement work more efficient. In addition, since the distance from the floor surface to the top end is large, combustion is further promoted. In this case, since the cavities of each combustion promoter are connected through the openings, an updraft of air accompanying combustion is easily generated and the rising speed is also fast, so the combustion speed is faster, and as a result, there is an advantage that the room can be heated in a short time.

[0010] In addition, if the above-mentioned composite combustion accelerators are connected and fixed so that adjacent hollow parts are connected to form a connected composite combustion accelerator, there is an advantage that preparations before combustion can be completed more quickly. Furthermore, since the adjacent combustion accelerators, composite combustion accelerators, and connected composite combustion accelerators are all aligned in height, when placing firewood, it is difficult for them to slip off, and preparation work can be completed quickly.

[0011] If the combustion promoter is made of a metal material such as stainless steel, it has the advantage of being reusable and durable. If the combustion promoter is made of a combustible material such as wood, it can also be used as fuel, so not only will the amount of firewood used be reduced, but the effort of cleaning up afterwards will be reduced. Furthermore, it has the advantage of being lighter than metal materials, making it easier to carry. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] An embodiment of the present invention will be described with reference to the drawings. Here, the term "polyhedron" refers to a polyhedron surrounded by four or more planes, and is composed of the edge parts of straight lines connecting the ridges of multiple vertices and the thick faces surrounded by these edge parts. Specifically, it refers to pyramids, hexahedrons, dodecahedrons, pentahedrons, etc. The hollow part refers to the inside of the space surrounded by the faces of the polyhedron, and the opening refers to a through hole opened in some or all of these faces. However, if the entire face is opened, the face will essentially disappear, so in this case the opening is formed by the space surrounded by the edge parts of other adjacent faces.

[0014] As shown in FIG. 1, a combustion promoter 1 for a wood stove according to an embodiment of the present invention (hereinafter, simply referred to as the "combustion promoter 1") is a rectangular parallelepiped, which is a hexahedron having six faces 2, and has a hollow portion 3 inside, and has three openings 4, two in the vertical direction and one in the horizontal direction, among the six faces 2. The openings 4 in the two upper and lower faces 2 in FIG. 1 are all open, and the outline of the opening 4 is formed into a square by the edge portions 21 of the four faces 2 surrounding it. The openings 4 may be provided in at least two faces 2, but preferably three or more faces 2. In this way, as shown in FIG. 9, no matter what position the wood stove A is placed in on the floor B during use, the two openings 4 will not necessarily face the floor B, so that the air circulation between the hollow portion 3 and the furnace of the wood stove A will improve, and combustion will be promoted. In the case where there are two openings 4, the same effect can be achieved by placing them so that the openings 4 do not face the floor surface B. The combustion promoters 1 can be placed on the floor surface B in a careful line, as described above, with the firewood C placed above them, but even if many combustion promoters 1 are placed randomly as if tossing them in and then the firewood C is placed on top of them, this creates more gaps between the combustion promoters 1 and improves the circulation of air with the upward current through the hollow portion 3 and openings 4, promoting combustion.

[0015] The same applies when the combustion promotion tool 1 is a polyhedron other than the above-mentioned hexahedron. The reason why it is a polyhedron is that the face portion 2 is flat, so that it is easy to create a composite combustion promotion tool 6 that is connected and fixed to each other, and because it is flat, it can be stably placed on the floor surface B.

[0016] Next, another embodiment shown in Figs. 2 to 5 will be described. This embodiment shows a composite combustion promoter 6 in which six combustion promoters 1 made of rectangular parallelepipeds, particularly square parallelepipeds, are assembled and fixed together. Each combustion promoter 1 has six faces 2, one cavity 3, and two openings 4 in which a pair of two opposing faces 2 are fully open. Each combustion promoter 1 is fixed together with the edge 21 of the opening 4 of the other four combustion promoters 1 surrounding the outer edge 21 of each opening 4. As a result of this fixing, as shown in Fig. 3, the openings 4 of the six combustion promoters 1 face each other to form a connected space 5, and a composite combustion promoter 6 is formed in which the hollow parts 3 of the six combustion promoters 1 and all the openings 4 are connected together through this connected space 5 through the hollow parts 3.

[0017] An example of using this composite combustion promoter 6 by placing it on the floor surface B of a wood stove A will be described with reference to Fig. 2. In this example, six combustion promoters 1 protrude in six directions from the connecting space 5 as the center, and the parallel edge portions 21 of the surface portions 2 of the lower two combustion promoters 1 are placed on the floor surface B and stabilized, while the parallel edge portions 21 of the surface portions 2 of the upper two combustion promoters 1 are positioned approximately parallel to the floor surface B. Fig. 4 also shows that the ridge portions 22 of the three combustion promoters 1 positioned below come into contact with the floor surface B, and the weight of the composite combustion promoter 6 is supported in a balanced manner at three points of the ridge portions 22 and stabilized, and the ridge portions 22 of the upper three combustion promoters 1 are at the same height. Furthermore, Figure 5 shows a combustion promotion device 1 constituting the composite combustion promotion device 6 shown in Figure 2, in which an opening 4 is formed on the entire surface of the face portion 2 and a notch 23 is formed in the edge portion 21, and a partial opening 4 is formed by hollowing out the center of the other face portion 2.

[0018] When in use, the two parallel edge portions 21 may be placed on the floor surface B as shown in Figures 2 and 5, or the ridge portion 21 may be supported at three points as shown in Figure 4, or it may be placed in another manner. Figure 5 shows a composite combustion accelerator 6 in which multiple cutouts 23 are formed in the edge portion 21 of the face portion 2 of the combustion accelerator 1 shown in Figure 2.

[0019] 6 shows an example in which both ends of a log C are placed on two parallel edge portions 21 located above two composite combustion promoters 6 that are erected on the floor by the two edge portions 21, forming a gap below the log C. In this case, if flammable paper or the like is placed below the log C and then ignited, air circulation improves through the hollow portion 3, opening 4, and notch 23 of the composite fuel promoter 6, which has the effect of promoting the combustion of the log A. Forming the notch 23 further improves air circulation, further promoting combustion.

[0020] The embodiment shown in Fig. 7 shows a connected composite combustion promotion device 8 in which the composite combustion promotion devices 6 shown in Figs. 2 to 4 are connected in a row in the longitudinal direction using a connecting rod 7. The connecting rod 7 is a long, thin rod with a rectangular cross section and an outer diameter that is approximately equal to or slightly smaller than the inner diameter of the fully open opening 4 of the face portion 2, and shows an embodiment of the connected composite combustion promotion device 8 in which the connecting rod 7 penetrates the opposing fully open openings 4 and connecting spaces 5 of two adjacent composite combustion promotion devices 6 and connects them in series.

[0021] In this embodiment, as shown in Fig. 8, the required number of firewoods C are placed on the floor B, for example, in two rows, and then both ends of the required number of connected composite combustion promoters 8 are placed in a direction perpendicular to the longitudinal direction of the firewood C, and similarly stacked up to two levels. In this case, as in the above case, if a firewood C is placed under the stack of flammable paper or the like and then ignited, the air flow will improve through the gaps between the firewood C and the connected composite combustion promoters 8 and the openings 4 and hollows 3 of the combustion promoter 1, allowing a large number of firewoods C to burn quickly, and the temperature in the room to rise quickly.

[0022] Next, another embodiment shown in Figs. 10 to 14 will be described. In this embodiment, the combustion promoter 1 is a composite combustion promoter 60 in which six rectangular parallelepipeds with different shapes and sizes are connected and assembled so that the hollow parts 3 of each are communicated through the openings 4 formed in the surface part 2, and the combustion promoter 1 has protruding parts in six directions. In the embodiment shown in Figs. 10 to 12, four combustion promoters 1 protruding in four directions on the same plane are connected and fixed to each other at the ends 21 of the surface part 2 having the openings 4 on the entire surface to form a cross shape, and as shown clearly in Fig. 11, two combustion promoters 11 with different shapes and sizes fixed at right angles to the openings 40 of the closing surface part 51 that closes the central connecting space 50 connected in this cross shape are connected to the hollow parts 3 of the other four combustion promoters 1 through the openings 41.

[0023] Fig. 13 shows a horizontally long connected composite combustion accelerating device 9 in which the corresponding openings 4 open on the entire surface of the composite combustion accelerating device 60 are arranged to face each other and connected and fixed via a connecting rod 7. Fig. 14 shows a horizontally long connected composite combustion accelerating device 10 in which the combustion accelerating device 11, which is small in shape and size, is inserted inside the opening 4 of the combustion accelerating device 1, which is large in shape and size. In this embodiment, all of the cavities 3 in the horizontal longitudinal direction are connected to each other, so that air circulation is improved and the combustion of the firewood C is further promoted. The method of use is the same as that of the embodiment of the connected composite combustion accelerating device 8 described above.

[0024] In the above description, the combustion promoter 1, the composite combustion promoter 6, and the linked composite combustion promoters 8, 9, and 10 are advantageously made of metals such as stainless steel, as they can be used repeatedly. If the materials are flammable materials such as wood, they can be used as part of the fuel, and since they are disposable, they can be left as ash in the furnace, eliminating the need for cleaning up. They are also lightweight and easy to carry.

[0025] In addition, even if the combustion promoter 1 in Fig. 1 is made into a polyhedron without the hollow portion 3 and the opening portion 4, as shown in Fig. 2, a certain degree of combustion promotion effect can be obtained because a large gap can be provided below and between the firewood A. In that case, the material can be either metal or wood.

[0026] As is clear from the above, when the combustion accelerating device 1, the composite combustion accelerating device 6, and the linked composite combustion accelerating devices 8, 9, and 10 of this invention are placed above the floor B of a wood stove A, a gap is formed between the device and the floor B, and a gap is also formed between the device and the wood C placed above the combustion accelerating device 1. This allows the rising air current from the floor B to the top of the furnace to be smoothly exhausted into the atmosphere through the chimney D. Furthermore, each combustion accelerating device 1 has a hollow section 3, which further promotes air flow through the hollow section 3, improving combustion efficiency, and when used in a house, the temperature inside the room can be raised, allowing for quick and efficient heating.

[0027] In the above embodiment, an example of use on the floor surface B inside the furnace of the wood stove A has been described, but it can also be effectively used for igniting firewood and other combustible materials outdoors, such as for barbecues and campfires. [Industrial Applicability]

[0028] Since it is easy to light firewood for a home wood stove or for a bonfire, which is a camping necessity, and burns quickly, it is expected that there will be a lot of demand for this product. [Explanation of symbols]
