Description

The present invention relates to an ignition structure useful for igniting charcoal.

Conventionally, for example, in Patent Document 1 (Japanese Unexamined Patent Publication No. 2018-178068), for the purpose of easily igniting a plurality of charcoals, a ventilation path for sucking air and discharging combustion gas is configured by the plurality of charcoals. We are proposing a charcoal structure.

As described in the same specification (0003) that "charcoal has poor ignitability", Patent Document 1 describes, for example, a three-dimensional air passage for inhaling air and discharging combustion gas with a plurality of "charcoal". Even if it is assembled and configured, it will not be easy because the ignition of charcoal is bad in the first place.

On the other hand, there is a so-called igniting agent for igniting charcoal. Three types of ignition agents are mainly known: gelled methanol, tablets made of solid hydrocarbons such as metaldehyde, and wood blocks impregnated with fats and oils and paraffin.

However, among the above ignition agents, those containing methanol as the main component are highly volatile and toxic, while those containing metaldehyde as the main component are also toxic, and paraffin-impregnated wood blocks explode suddenly. Although there is no danger, strong firepower and smoke are generated, and all of them have difficulty in using them safely and securely.

Japanese Unexamined Patent Publication No. 2018-178068

The problem to be solved by the present invention has been made in view of the fact that it takes time to ignite a plurality of charcoals, and there is a question about safety when igniting using an ignition agent made of a commercially available chemical. It is intended to provide articles useful for igniting charcoal.

In order to solve the above problems, the present invention is an ignition structure used for igniting charcoal, and at least two rods are arranged in a horizontal direction by an assembly rod made of a flammable rod. Multiple layers are assembled up and down, and the assembly rods that intersect each other in contact with each other are constrained in the horizontal position by the rod restraint portion, and charcoal is used by the ends of the assembly rods. A configuration in which a corner portion on which the steel is leaned, a central portion on which charcoal is leaned between the ends of the assembly rods constituting the corner portion, and an insertion port formed by the plurality of layers of the assembly rods are formed. And said.

In the ignition structure of the present invention, a layer in which at least two assembly rods are arranged is assembled, and at this time, the lateral positions of the assembly rods that abut each other and intersect with each other by the rod restraint portion are set in the lateral direction. Restrain and assemble the ignition structure. Then, for example, the assembly rod located at the lower part of the ignition structure is ignited. In the ignition structure of the present invention, the assembly rod is flammable, and if a piece of wood is used, for example, it can be ignited more easily than charcoal.

That is, in the ignition structure of the present invention, when the assembly rod located at the lower part is ignited, air is taken into the structure from each other's assembly members to promote combustion, while the inside of the structure is from the bottom to the top. The so-called chimney effect can be obtained by creating an air flow. This chimney effect allows charcoal to be ignited without the need for such work, where air would normally have to be supplied by a bellows or a fan. Further, in the present invention, by having the bar material restraining portion, the overall shape of the ignition structure in which the chimney effect is generated can be maintained for a long time without collapsing until the charcoal is sufficiently ignited.

It is a figure which shows the ignition structure of this invention. It is a figure which shows an example of the assembly kit which creates the ignition structure of this invention. It is a figure which shows the state of the housing just before the use of the ignition structure of this invention. It is a figure which shows the state after the assembly of the ignition structure of this invention, and before ignition. It is a figure which shows the state which the charcoal leaned after assembling the ignition structure of this invention. (A) to (c) are the figures which show the modification of the assembly bar and the bar restraint part in the ignition structure of this invention, respectively.

The present invention is an ignition structure that easily ignites a plurality of charcoals without using an ignition agent made of a commercially available chemical, and at least two rods are provided by an assembly rod made of a flammable rod. A plurality of layers arranged in the horizontal direction are assembled one above the other, and the assembly rods intersecting each other in contact with each other are restrained in the lateral position by the rod material restraining portion, and the assembly rods are constrained. Inserted by the corner portion where the charcoal is leaned by the ends of the materials, the central portion where the charcoal is leaned between the ends of the assembly rods constituting this corner portion, and the group of the assembly rods having a plurality of layers. It is said that the mouth is formed.

Here, the flammable bar means that it can be ignited more easily than charcoal, and for example, a piece of wood or synthetic paper is assumed. Further, assembling a plurality of layers in which at least two assembly rods are arranged means, for example, that the ignition structure has a grid shape in a plan view. Further, the bar restraint portion may not be moved from the placement position in each layer where the assembly bar is placed, for example, and may be adhered with, for example, flammable rice glue.

Further, in the present invention, in the above configuration, the bar material restraining portion may be formed on the assembly bar material. When the bar material restraint portion is formed on the assembly bar material, it is assumed that a recess is formed as the bar material restraint portion, for example. By doing so, it is possible to prevent the whole piece from collapsing when the fire burns to the piece of wood after ignition, and the chimney effect can be maintained until the charcoal is sufficiently ignited.

Further, the ignition structure of the present invention is capable of accommodating a plurality of assembly rods so as to be assembled in the above configuration, and has a flammable housing used for ignition of the assembly rods assembled in the structure. It may be configured to have. The flammable housing is assumed to be made of a material that is easier to ignite than the assembly rod material, for example, a paper material such as cardboard. By doing so, a plurality of assembly rods can be stored compactly, and when in use (when charcoal is ignited), the housing can be taken out from the housing and then the housing itself can be used as the ignition material. Therefore, no dust remains on the spot.

Hereinafter, specific examples of the present invention will be described with reference to FIGS. 1 to 6. In the figure, 1 is the ignition structure of the present invention. In the case of this example, the ignition structure 1 is formed in a flammable, for example, paper housing 2, and a plurality of flammable assembling rods, for example, wood pieces 3 housed in the housing 2. It is provided with a recess 3a as a bar restraining portion.

The housing 2 is configured in a size that can be mailed by mail, for example, and after assembling the piece of wood 3, it is unfolded and rolled as shown in FIG. 3 to be used as an ignition material. That is, the housing 2 does not generate dust to be brought back after barbecue, for example, as a storage of wood pieces 3 before charcoal ignition and as an ignition material at the time of charcoal ignition, and the entire configuration can be used without waste.

In this example, since the housing 2 is configured in a size that can be mailed as described above, the size and number of wood pieces 3 that can be stored in the housing 2 are used. Twelve pieces of wood 3 are prepared, for example, by cutting square timber having a height of 22 mm and a width of 18 mm at an end surface evenly with a length of 180 mm in the longitudinal direction.

The material of the wood piece 3 is not limited as long as it is a commercially available wooden square wood (charcoal may be used if a rod-shaped restraint portion is formed), but it is more flammable than charcoal, for example, coniferous trees such as pine, cedar, and hinoki. In addition to using wood, synthetic wood may be used, and combustible materials such as synthetic paper (which is not harmful when burned) may be used instead of wood. In addition, the piece of wood 3 is not limited to the above dimensions and may have an appropriately required size, but it is basically desirable to use it in a home barbecue or the like and adopt a suitable size.

The wood pieces 3 shown in FIGS. 1 to 5 are located at positions about 50 mm in the longitudinal direction, for example, from each of both ends of the wood piece 3 in the longitudinal direction toward the center in the longitudinal direction, at two locations on the upper surface and the lower surface in the height direction. Recesses 3a are formed in (a total of four places for each piece of wood 3). The recess 3a has a depth of about 20% (about 5 mm) with respect to the height of the piece of wood 3, and the width inside the recess is slightly wider than the width of the piece of wood 3, for example, 20 mm. The rod material restraining portion is not limited to the dimensional conditions of the recess 3a, and may have an embodiment as shown in FIG. 6 described later in addition to the recess 3a, and has a fitting structure such as the recess 3a. It is also included in the case of joining each other with rice glue (which is not harmful by burning).

In the case of this example, the ignition structure 1 has two pieces of wood 3, 3 spaced parallel to each other in the longitudinal direction so that the ends of the pieces of wood 3, 3 are in the same direction on the installation surface, as shown in FIG. The layers are formed by opening and arranging them on the same plane. This is referred to as layer A.

Further, in the ignition structure 1, the ends of the other two wood pieces 3 and 3 are placed on the upper part of the A layer at, for example, 90 degrees from the end direction of the two wood pieces 3 and 3 of the A layer. By fitting the two pieces of wood 3 and 3 in the recesses 3a and 3a of the layer A toward the other direction in which they are rotated, layers arranged on the same plane at intervals parallel to the longitudinal direction are formed. This is referred to as layer B.

Then, the A layer and the B layer are alternately stacked in the vertical direction, and in the case of this example, all 6 layers are in the state as shown in FIGS. 1 and 4 and 5 (in a plan view, a girder shape). The charcoal C has a corner portion 1a formed by the ends of the wood pieces 3 constituting the A layer and the B layer, and a central portion 1b formed between the ends of the wood pieces 3 constituting the corner portion 1B. Lean against.

In this example, for example, after leaning against the charcoal C corner portion 1a and the central portion 1b, the housing 2 is unfolded and rolled, the tip of the housing 2 in this state is ignited, and the housing 2 is alternately ignited in the vertical direction from the ignited side. It is inserted into the central insertion slot 1A formed by the three groups of stacked A and B layers of wood.

For example, the housing 2 may be rolled up and inserted into the insertion slot 1A, and then the housing 2 may be ignited through a gap between the wood pieces 6 in the lower layer of all six layers. In this case, the charcoal C may be leaned against the corner portion 1a and the central portion 1b after the ignited housing 2 is inserted into the insertion port 1A.

After a while, the fire that ignited the housing 2 burns to the wood piece 3 in the lower layer, and gradually the fire burns upward from the lower layer due to the so-called chimney effect in the insertion port 1A, and this fire burns to the wood piece 3 one after another. It burns and burns to charcoal C and ignites.

As a process of igniting the charcoal C, in the ignition structure 1, when the fire is transferred from the housing 2 to the wood piece 3, new air outside the structure is created from the gap between the wood pieces 3 assembled by the updraft generated by the lower fire. On the other hand, the air that has flowed into the structure from outside the structure creates an upward airflow in the central portion 1b, which promotes the momentum of the fire (chimney effect). At this time, if the ignition structure 1 easily loses its overall shape due to the uneven burning of the wood pieces 3, the chimney effect is reduced, but in the present invention, the bar material restraining portion is formed. The overall shape is maintained for a long time, the chimney effect is sustained, and after the housing 2 is ignited, the charcoal C can be ignited without supplying air with a fan or a bellows.

In addition, as a configuration in which the bar material restraining portion is formed on the wood piece 3, for example, as shown in FIG. 6A, a shape in which the corrugated concave portion 3a and the convex portion 3b are gently continuous in a corrugated shape in a side view, for example. As shown in FIG. 6B, the upper convex portion 3b is positioned on the opposite surface of the upper wood piece 3 from the facing surface, and the lower convex portion 3b is the facing surface of the lower wood piece 3 from each other. The shape may be such that the wood piece 3 itself is easily burned as shown in FIG. 6 (c), and the hole 3c is formed in order to improve the ventilation efficiency as a whole.

Further, in the number and arrangement of the wood pieces 3 in each of the layers A and B in the above embodiment, at least the insertion port 1A is formed in each layer, and the corner portion 1a and the central portion 1b on which the charcoal C is leaned are formed. If there is, there is no particular limitation. Further, the number of layers in the vertical direction (6 layers in the above embodiment) and the number and arrangement of the wood pieces 3 due to the number of layers are not limited as long as the above conditions are satisfied.
