Abstract

PROBLEM TO BE SOLVED: To provide a charcoal structure anyone can ignite easily.SOLUTION: A charcoal structure 1 is formed for making up an air path 1c, by fixing a charcoal 11 through an adhesive tape, glue or the like 2, the adhesive strength or adhesive force of which is reduced by a combustion heat. When ignition agents 3 arranged in a lower portion of the charcoal structure 1 and adjacent to an inlet port 1a are ignited, an upward current occurs in the air path 1c due to the combustion, so that the combustion gas is discharged from an outlet port 1b provided in an upper portion of the charcoal structure 1, and air is simultaneously fed from the inlet port 1a. Accordingly, combustions of the ignition agent 3 and the charcoal 11 are promoted, thereby igniting the charcoal 11 easily. After igniting the charcoal 11, the adhesive strength or adhesive force of the adhesive tape, the glue or the like 2 is reduced, and thereby the charcoal structure 1 can be used for applications, such as barbecue, by chipping the structure away and laying out the charcoal 11 flat.SELECTED DRAWING: Figure 5

Description

Detailed Description of the Invention

  The present invention relates to fuel charcoal. More specifically, the present invention relates to a charcoal structure in which ignition is facilitated by fixing a plurality of charcoals.

Technology background

  Charcoal for fuel has long been used in general homes for cooking and heating, but now that city gas and induction cookers have become widespread, it has almost never been used in general homes. On the other hand, in recent years, the culture of enjoying barbecue outdoors has prevailed widely in general, and in such a scene, charcoal for fuel is still used today.

  However, charcoal has poor ignitability and can not be ignited with a lighter. For this reason, it is often seen that people are struggling to create a fire at a barbecue area. Charcoal for fuel is required to be able to easily ignite by overcoming this poor ignitability.

A hand-shaped tool with a hole in the bottom is known as a device to facilitate ignition of charcoal (Patent Document 1). In addition, a similar device in consideration of storability by folding is also marketed under the name of charcoal starter. Anyone can easily ignite charcoal by putting charcoal and putting fire from below. On the other hand, there is a problem that it takes another time to clean and store the appliance itself.
Patent Document 2 discloses a charcoal package in which a crushed charcoal is packed in a flammable frame. However, when the frame burns out, it becomes difficult to efficiently hit the flame generated by the ignition tool to charcoal, so it is not suitable for white charcoal, oga charcoal, etc. which require a long time until ignition.

Several types of charcoal may be combined and used in one charcoal structure.
In addition, charcoal which is made to be able to be easily ignited by a lighter or the like by applying an ignition agent or the like is also suitable. By using all or part of the charcoal 11 constituting the charcoal structure 1, ignition can be performed without separately preparing an ignition agent and the like.

  Although the charcoal 11 is illustrated by the rectangular parallelepiped in FIGS. 1-6, this does not limit the shape of the charcoal 11 to a rectangular parallelepiped, and charcoal of various shapes can be used.

[Airway 1c]
The charcoal structure 1 needs to be provided with at least one air passage 1c surrounded by charcoal 11 on all sides. As will be described in detail later, when the adhesive tape or putty 21 is used to fix the charcoal 11, it is not the charcoal 11 that directly contacts the air passage 1c, but the adhesive tape or the adhesive tape using the charcoal 11 It may be putty 21 etc. In such a case, it is not necessary for the air passage 1c to be in direct contact with the charcoal 11 in all directions, and a part or all of the way 1c may be surrounded by the charcoal 11 via the aforementioned adhesive tape or putty 21 or the like. .
Further, as shown in FIG. 5, when the charcoal structure 1 is used by being placed on the installation surface 6 having no air permeability such as firebrick, the installation surface 6 having no air permeability such as firebrick may be made of air. It may play one side of the path 1c.

In the example of FIG. 2, the intake port 1 a is provided at the bottom of the charcoal structure 1. A barbecue stove is usually made of a metal storage box made of metal grids and perforated metal plates, and has a structure that allows air to pass through. Therefore, when used by placing it on a breathable installation surface 5 such as a barbecue stove charcoal storage place, supplying air to the air passage 1c by providing the air inlet 1a on the bottom of the charcoal structure 1 Is possible.
However, in the case where the charcoal structure 1 is used by placing the charcoal structure 1 on a non-air-permeable installation surface 6 such as a firebrick, suction can not be performed from the bottom of the charcoal structure 1. In that case, as shown in FIGS. 4 and 5, it is necessary to provide an air inlet 1 a on the side of the charcoal structure 1. In addition, it is not necessary for one side of the inlet 1a provided on the side to be in contact with the installation surface 6 having no air permeability such as a firebrick, etc., as shown in FIG. It may be.
In addition, it is necessary to provide the air intake 1a in the side surface of the charcoal structure 1 which is used by placing it on the installation surface 6 which is not air-permeable such as firebrick. On the other hand, the position of the intake port 1a is not limited to only the bottom of the charcoal structure 1 with respect to the charcoal structure 1 used by being placed on the breathable installation surface 5 such as a barbecue stove charcoal yard etc. It may be on the side of the structure 1. Furthermore, the inlet 1 a may be provided on both the bottom and the side of the charcoal structure 1.

As shown in FIGS. 4 and 6, the number of intake ports 1a may be more than one for one air passage 1c.
Although the size of the intake port 1a varies depending on the size of the charcoal structure 1, the combined area of all the intake ports 1a provided in the charcoal structure 1 is preferably 900 to 600,000 square millimeters.

  In FIGS. 2 and 4 to 6, the shape of the intake port 1a is shown as a square, but this does not limit the shape of the intake port 1a to a square, and the shape of the intake port 1a is polygonal, circular, etc. It may be a more complicated shape.

[Exhaust port 1b]
The exhaust port 1b is at the top of the charcoal structure 1 and is connected to the air passage 1c. The most basic structure of the exhaust port 1b is shown in FIG. In the example of FIG. 2, the exhaust port 1 b is provided on the upper surface of the charcoal structure 1. Thus, the combustion gas generated in the air passage 1c can be exhausted by the updraft generated by the combustion.
However, the position of the exhaust port 1 b is not limited to the upper surface of the charcoal structure 1, and may be disposed on the side of the charcoal structure 1 as shown in FIGS. 4 and 5. Furthermore, the exhaust port 1 b may be provided on both the upper surface and the side surface of the charcoal structure 1.

As shown in FIGS. 4 and 5, the number of exhaust ports 1b may be plural for one air passage 1c. In addition, although the exhaust port shown to FIG. 4 and 5 is located in the side of the charcoal structure 1, when this is equipped with the several exhaust port 1b, the position of the exhaust port 1b is limited to the side of the charcoal structure 1. Instead, the upper surface of the charcoal structure 1 may have a plurality of exhaust ports 1b, or both of the upper surface and the side surface of the charcoal structure 1 may have a plurality of exhaust ports 1b.
Although the size of the exhaust port 1b varies depending on the size of the charcoal structure 1, the combined area of all the exhaust ports 1b provided in the charcoal structure 1 is preferably 900 to 600,000 square millimeters.

  Although the shape of the exhaust port 1b is shown as a square in FIGS. 1 to 6, this does not limit the shape of the exhaust port 1b to a square, and the shape of the exhaust port 1b is polygonal, circular, etc. It may be of any shape.

[Adhesive tape, adhesive etc. 2]
In the examples of FIGS. 4 to 6, adhesive tape, adhesive agent 2 and the like 2 are used to fix the charcoal 11. The charcoal 11 is mutually fixed by interposing an adhesive tape, an adhesive, etc. 2 in the interface of charcoal 11 adjacent mutually, and the charcoal structure 1 is formed.
The pressure-sensitive adhesive tape, the adhesive and the like mentioned in this document generally mean one which fixes the charcoal 11 to each other by being interposed at the interface between the charcoal 11. A tape having an adhesive layer on both sides, an adhesive, a paste, an adhesive resin or rubber, a thermoplastic resin called a so-called hot bond, and the like are examples thereof.

It is characterized in that the charcoal 11 which has been fixed becomes separable because it disappears or the adhesive tape, adhesive agent, etc. 2 burns, evaporates, sublimes or melts.
The adhesive tape, the adhesive agent 2 and the like may be any one as long as the above-mentioned properties are satisfied, but starchy paste is preferable, as an example. The starch paste has sufficient adhesive power before ignition and can fix the charcoal 11, and it is denatured by heat to weaken the adhesive power, so the charcoal 11 can be easily separated after ignition.

Methods of fixing charcoal 11 include a method using adhesive tape, adhesive agent 2 and the like, a method using adhesive tape and patties 21 described in detail later, and a method using strings 22 described in detail later. . In the example of FIGS. 1-6, the charcoal 11 is fixed using only any one. However, this is not limited so that only one method must be used to form one charcoal structure 1, and a plurality of methods may be used in combination. Also, it may be used properly depending on the place.
Furthermore, as for the pressure-sensitive adhesive tape, the adhesive agent 2 and the like, a plurality of types may be used to form one charcoal structure 1. For example, the charcoal 11 may be fixed using an adhesive tape and an adhesive in combination, or the adhesive tape and the adhesive may be used depending on the place.

[Adhesive tape, putty, etc. 21]
In the examples of FIGS. 1 and 2, an adhesive tape, putty or the like 21 is used to fix the charcoal 11. By attaching an adhesive tape, putty or the like 21 to the surface excluding the interface between the charcoal 11 adjacent to each other, the charcoal 11 is mutually fixed via the adhesive tape, putty or the like to form a charcoal structure 1.
In the example of FIGS. 1 and 2, the adhesive tape, putty, etc. 21 is attached only to the surface in contact with the air passage 1c, but this limits the surface to which the adhesive tape, putty, etc. 21 is attached to the air passage 1c. Instead, it may be attached to the outer surface of the charcoal structure 1.
Examples of the adhesive tape and putty 21 include a tape having an adhesive layer on at least one side, a putty made of resin, an adhesive resin or rubber, an adhesive in which particles and powder are mixed, and paste.
The adhesive tape, putty 21 etc. have weak adhesion or adhesiveness due to either charcoal 11, adhesive tape, adhesive 2 etc., cord 22 etc. or ignition agent 3 detailed later, or plural combustion heats and flames It is characterized in that the charcoal 11 which has been fixed becomes separable because it disappears or the adhesive tape, putty or the like 21 burns, evaporates, sublimes or melts.
The adhesive tape, putty, etc. 21 may be any material as long as the above-mentioned properties are satisfied, but to give an example, an adhesive in which granular or powdered wood or charcoal is mixed is obtained when the thermal power at the time of combustion is obtained. And is preferable because it promotes the ignition of the charcoal 11.

As described in the description of the pressure-sensitive adhesive tape, the adhesive, etc. 2, when forming one charcoal structure 1, to fix the charcoal 11, the pressure-sensitive adhesive tape, the adhesive, etc. 2, the pressure-sensitive adhesive tape, putty, etc. Not only one of the methods of the string 22 and the like to be described may be used, but a plurality of methods may be used in combination or depending on the place.
Moreover, several types may be used also in forming the one charcoal structure 1 also about an adhesive tape, putty, etc. FIG. For example, the charcoal 11 may be fixed by using the adhesive tape and the resin putty in combination, or the adhesive tape and the resin putty may be used depending on the place.

[Strings etc. 22]
In the example of FIG. 3, a string 22 or the like is used to fix the charcoal 11. The charcoal 11 is fixed to each other by winding a string or the like 22 on both charcoals 11 adjacent to each other to form a charcoal structure 1.
Also, in addition to the method of directly fixing charcoal 11 together, a frame is made of wood, paper or the like, and by tying cords 22 to the frame and charcoal 11, the charcoal 11 is mutually fixed through the frame. It is also good.
As an example of the string etc., a string, a thread, a rope, a film of paper or resin, a belt, an adhesive tape with an adhesive layer on one side or both sides, etc. can be used.
The string etc. 22 is either charcoal 11, adhesive tape, adhesive 2 etc., adhesive tape, putty etc 21 or any of the ignition agents 3 detailed later, or all or one of the strings 22 by a plurality of combustion heats and flames. It is characterized in that the fixed charcoal 11 becomes separable by combustion, evaporation, sublimation or melting of the part.
The string 22 may be anything as long as it meets the above-mentioned properties. For example, using a combination of noncombustible cord-like material such as a wire or metal wire and a flammable material like a cord, a structure in which charcoal 11 can be separated by burning the cord part You may

As described in the description of the pressure-sensitive adhesive tape, the adhesive, etc. 2, when forming one charcoal structure 1, to fix the charcoal 11, the pressure-sensitive adhesive tape, the adhesive, etc. 2, the pressure-sensitive adhesive tape, the putty, etc. 21, the string, etc. Not only one of the 22 methods may be used, but a plurality of methods may be used in combination or depending on the location.
Moreover, also about a string etc., multiple types may be used in forming one charcoal structure 1. As shown in FIG. For example, after the cord 11 is wound and the charcoal 11 is fixed, the resin film may be further wound and reinforced, or the cord and the resin film may be properly used depending on the place.

[Ignition agent 3]
The ignition agent 3 is installed in the air passage 1c as shown in FIGS. The ignition agent 3 is fixed to the charcoal structure 1 by an adhesive, an adhesive tape, a cord or the like, or the ignition agent 3 is hooked to the charcoal structure 1 or a structure which does not easily fall off. Or, by blocking part or all of the intake port 1a and the exhaust port 1b with a flammable paper, resin film or the like, the ignition agent 3 is prevented from falling off, thereby being integrated with the charcoal structure 1 .
The position of the ignition agent 3 may be anywhere in the air passage 1c, but the workability when igniting the ignition agent 3 and the heat and flame from the combustion of the ignition agent 3 are applied efficiently to the charcoal 11 Considering it, it is preferable to install in the vicinity of the intake port 1a.

  As a material of the ignition agent 3, those generally used as an ignition agent for charcoal can be used. For example, it is possible to use wood, paper, granular or powdery shaped wood or charcoal, molded gel-like fuel, solidified organic matter such as alcohol, etc. In addition to charcoal, an ignition agent can be used. It is also preferable to apply one that can be easily ignited by a lighter or the like.

[Charcoal 4 which is excellent in ignitability compared to charcoal 11]
As shown in FIG. 6, charcoal 4 which is superior to the charcoal 11 in ignitability is installed in the air passage 1c. Charcoal 4 which is excellent in ignitability in comparison with charcoal 11 is fixed to the charcoal structure 1 with an adhesive, adhesive tape, string or the like, or charcoal 4 which is excellent in ignitability in comparison with charcoal 11 is used in the charcoal structure 1 The charcoal 11 and the charcoal 11 or the vent 1b are partially or entirely covered with a flammable paper or resin film or the like so that they can be caught or fitted so as not to be easily dropped off. The charcoal 4 is integrated with the charcoal structure 1 by preventing the charcoal 4 which is excellent in ignitability from falling off.
The position of the charcoal 4 which is excellent in the ignitability as compared with the charcoal 11 may be anywhere in the air passage 1c.

If the material of the charcoal 4 which is excellent in the ignitability compared with the charcoal 11 is good in ignitability when compared with the charcoal 11, various charcoals, such as white charcoal, black charcoal, and molding charcoal, can be used. When a plurality of types of charcoal having different ignitability are used as the charcoal 11, the charcoal 4 having better ignitability compared to the charcoal 11 is ignitable compared to the charcoal having the least ignitability among them. It may be the same as that of the charcoal used as the charcoal 11 or may be worse in ignitability than that. For example, in the case of a charcoal structure 1 in which three types of black charcoal with poor ignitability, molded charcoal with good ignitability, and black charcoal having an intermediate level of the ignitability are used as charcoal 11 are compared with charcoal 11. Charcoal 4 which is excellent in ignitability may be any charcoal which is excellent in ignitability as compared with oga charcoal, and black or molded charcoal which is used as charcoal 11 may be used.
Moreover, if it is excellent in ignitability compared with the charcoal 11, even if it is the charcoal of the same kind as charcoal 11, it can be used as charcoal 4 which is excellent in ignitability compared with charcoal 11. An example of such is charcoal. The thing which extinguished by suffocating charcoal which was once ignited is said to be extinguished charcoal. This burnt charcoal is superior in ignitability to the same kind of charcoal which has not been ignited yet. That is, the charcoal 11 of the charcoal structure 1 and the charcoal of the same kind of charcoal can be used as charcoal 4 which is excellent in ignitability compared with charcoal 11. As another example, the case where the ignition property is improved by applying an ignition agent to charcoal of the same type as that used for charcoal 11 or the like is used as charcoal 4 which is superior to the charcoal 11 in ignitability Is considered.
