Description

[Detailed description of the invention] <Industrial application field> This invention relates to a small portable stove whose charcoal storage container is made of a nonflammable thin metal plate such as aluminum foil. It is designed to burn efficiently.

《Prior Art》 There has been a demand for small and portable charcoal fuel as a small fuel that can be easily carried and used during outdoor leisure activities, and as a fuel that can be stored in everyday life and easily used in emergencies. Ta.

Furthermore, small tabletop stoves were used to boil and heat food at indoor dining tables in inns and restaurants, but the fuel used in this case could be gaseous fuel, liquid fuel, solid fuel, etc. At present, chemical agents are far more often used as solid fuels than charcoal.

However, although charcoal grilling has been popular because it has a delicious and emotional flavor, a small portable charcoal stove that is clean and easy to use has not been proposed.

Therefore, the applicant of this application first applied for utility model No. 61-122811.
No. 1, we proposed a small charcoal stove consisting of a cup-shaped storage container made of a nonflammable metal thin plate such as aluminum foil, and combustion charcoal packed inside the container.

However, such portable small stoves do not need to burn for tens of hours, and are used for boiling relatively simple dishes or secondary processing of already processed dishes, so they only burn for 20 to 30 minutes at most. A combustion time of one hour or less was sufficient.

In addition, what is required is a combustion method that increases the flame power immediately after ignition, rather than a combustion method that gradually burns and generates thermal power after ignition.

<<Problems to be solved by the invention>> Therefore, the applicant of the present application further improves the previous invention and proposes a portable and small-sized charcoal stove that can burn efficiently.

<Means for Solving the Problems> In order to solve the above-mentioned problems, this invention has a cup-shaped storage container formed from a non-combustible metal thin plate such as aluminum foil, and a container body that is inserted into the storage container. a primary rostol forming a space at the bottom; an ignition material placed on the primary rostrum; a second rostrum inserted into the container to form a space above the ignition material; An air intake port is formed in the side wall of the container corresponding to the space formed by the combustion coal placed on the secondary rooster and at least the primary rooster.

<<Example>> Reference numeral 1 denotes a storage container body for charcoal fuel, which is formed of a non-flammable metal thin plate such as aluminum foil, and the overall shape of the container body 1 has an opening 11 on the top surface.
It is shaped like a cup whose diameter becomes slightly smaller toward the bottom.

Reference numeral 2 denotes a primary rooster installed in the container 1, which has ventilation holes 21 on the top and side surfaces, and is formed into a trapezoidal shape with an open bottom. form.

Reference numeral 3 denotes an ignition material in which a plurality of vertical ventilation holes 31 are formed, and is placed on the primary roaster 2 .

4 is a secondary rooster, which has ventilation holes 41 on the top and side surfaces, is formed in an inverted concave shape with a slightly smaller diameter on the lower end surface, and the side surface is inserted along the side wall of the container 1 to carry the ignition material. A space 13 is formed in the upper part of 3.

5... is combustion coal, which is stacked on the secondary roost 4.

Reference numeral 6 denotes an air intake port formed at a location corresponding to the space 11 formed by the primary rooster 2 on the side wall of the container 1, and 7 corresponds to the space 13 formed by the secondary rooster 4. This is an air intake hole formed in the position.

Note that a plurality of these air intake ports 6 and 7 may be provided.

Further, although the drawings show an embodiment in which the air intake port 7 is formed, the air intake port 7 may be omitted if necessary.

《Operation》 Since this device has the above-mentioned configuration, it is covered with a plastic film etc. when not in use, and when in use, when the cover is removed and the air intake port 6 is ignited with a match, the igniting material 3 is instantly ignited. Then, the upper combustion coal 5 is ignited and combustion starts.

After that, the ignition material 3 burns out and becomes ash, but the second
This ash and the burnt coal 5... are separated by the next roaster 4 and do not come into direct contact with each other, so the burnt coal 5...
will not be crushed by the weight of the

Therefore, each of the ventilation holes 21 of the primary nozzle 2 is not clogged, and good ventilation can be maintained at all times.

In addition, the ignition material 3 which becomes ash for the burning coal 5...
It does not burn on the top, but is placed on the second rostrum 4, so it has a good footing, and even if it gradually turns into ash from the bottom, it can continue to maintain good ventilation in a relatively stable state. I can do it.

When the ventilation hole 7 is provided, the combustion efficiency is better than when only the ventilation hole 6 is provided, but when igniting, the fire flows through the hole 7.
Since the stove may blow out more air, it is suitable for use by being inserted into a tabletop stove, and if the stove is to be used directly, such as outdoors, it is better to use one with only the ventilation holes 6.

[Effects] As described above, in this invention, the burning coal is not directly stacked on the igniting material placed on the primary roost, but is placed on the second roost. Therefore, the ignition material and the combustion coal can be separated from each other to form a space.

Therefore, the igniting material, which has become residual ash, is not crushed by the charcoal and impedes the ventilation action of the primary roaster, resulting in a stove with high combustion efficiency.

Therefore, it is possible to create a stove with a stronger fire even with a smaller amount of burning charcoal than conventional ones, and it is also effective as a light and small portable stove for snacking during outdoor leisure activities and as a fuel for small tabletop stoves indoors. .
