Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large pot combustion apparatus used mainly in emergency disasters and outdoor events.

[0002]

2. Description of the Related Art A large-sized cooking pot used in an emergency disaster or at various events outdoors mainly uses a combustion device having a mechanism for securing thermal power using peat or firewood. . In general, such a combustion device is provided with a combustion section inside a cylindrical housing, and puts the peat or wood on the combustion section and burns the fire, thereby causing a fire in the housing. It was raised continuously, and further, a large pot was placed on the upper end of the storage section, so that foods and the like contained in the large pot were cooked.

[0003]

However, in the above-described combustion apparatus, the flame generated in the combustion section hits the entire bottom portion of the large pot in a sparse state, and is consumed until the entire space in the housing is warmed. Since it takes a long time, the combustion efficiency is very poor, and there is a problem that the food in the large pot cannot be efficiently boiled unless a larger heat is generated in the combustion part. Further, since it is necessary to generate a large thermal power in the combustion section as described above, for example, in an open portion such as an air intake hole, a flame is blown out to the outside of the combustion device with strong force, and this combustion device There is also a problem that there is a danger to those who engage in cooking operations around the area.

Accordingly, an object of the present invention is to provide a combustion apparatus for a large pot that dramatically improves the efficiency of burning the large pot and does not involve danger during use.

[0005]

In order to achieve the above object, the present invention according to claim 1 of the present invention provides an outer peripheral wall having a cylindrical shape and capable of supporting a large pot on an upper portion thereof, and an outer peripheral wall extending along the outer peripheral wall. And a combustion portion held in the inner peripheral wall, the inner peripheral wall being erected at an interval over the entire inner periphery, and a combustion unit held in the inner peripheral wall. The divided space is vertically divided, and a flame collecting portion having a flame passage hole at the center for communicating the divided spaces is provided at a position above the combustion portion.

[0006] Here, the combustion part is, for example, peat or firewood,
It is a concept that includes everything that is used to generate thermal power in a combustion device, such as a roast or ash pan. In addition, the position where the combustion part is held is a position in the space within the inner peripheral wall where the flame can be constantly applied to the bottom of the installed large pot.
It can be installed anywhere. Furthermore, the shape of the flame collecting portion is not particularly limited as long as it can block at least the flame rising along the inner peripheral wall and can pass the blocked flame toward the flame hole.

[0007] With this configuration, the flame generated in the combustion section first strikes the entire lower end face of the flame collecting section, and the flame blocked by the flame collecting section is the flame passing in the center of the flame collecting section. It will be concentrated and directed toward the hole. The flame that has passed through the flame holes intensively strikes the bottom of the large pot, so that the food in the large pot can be efficiently heated. Further, since the flame generated in the combustion part is blocked by the flame collection part, the installation distance between the outside and the combustion part becomes long.For example, in the air intake hole provided in the outer peripheral wall, the flame is intense to the outside. It does not blow out.

Further, the flame collecting portion may be integrally fixed to the inner peripheral wall. However, as in the second aspect of the present invention, the flame collecting portion is detachable via a supporting member in the inner peripheral wall. The inspection and replacement of the flame collecting portion can be easily performed.

Here, the supporting member may be any member as long as the flame collecting portion does not fall below the inner peripheral wall when the flame collecting portion is installed. Specifically, the supporting member is formed on the inner peripheral surface of the inner peripheral wall. Metal fittings fixed at a plurality of locations with an interval, or those having a convex surface formed on the entire inner peripheral surface side of the inner peripheral wall may be used.

Further, in the invention according to claim 3, since the flame collecting portion is formed in a hat shape inclined downward toward the entire periphery of the outer edge with the flame hole as a center, the flame collecting portion is formed in the combustion portion. The flame is smoothly swept toward the through hole, and the flame can be more efficiently applied toward the bottom of the large pot placed on the combustion device.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the large pot combustion apparatus of the present invention will be described below. First, a general description of the large pot combustion device of the present invention will be given. As shown in FIG. 1, the large pot combustion device has a cylindrical outer peripheral wall 1 having a plurality of air intake holes 8 at an upper end. A double-walled inner peripheral wall 2 erected at a constant interval 17 over the entire inner periphery of the outer peripheral wall 1;
A combustion portion 3 held at a lower portion of the inner peripheral wall 2, a firing port 9 penetrating the outer peripheral wall 1 and the inner peripheral wall 2 and leading to the combustion portion 3, and a plurality of fasteners in a space 4 in the inner peripheral wall 2. Shade-shaped flame collecting portion 5 having a central flame-passing hole 6 which is held through
And

Here, first, the configuration of the combustion unit 3 will be described in detail. This combustion unit 3 has a rectangular ash tray 12.
And a dish-shaped roaster 11 placed over the ash tray 12.
And peat 13 placed on the rostrum 11. When the combustion section 3 is attached to the inner peripheral wall 2, the combustion section 3 is held by a support 19 fixed between the left and right shielding plates 10, 10 fixed to the lower portion on the inner peripheral surface side of the inner peripheral wall 2. A flame is generated in the space 4 in the peripheral wall 2 from below. Also, peat 1
The ash and dust No. 3 are stored in the ash tray 12 via the rostrum 11, and the ash tray 12 containing the ash and dust can be easily taken out of the combustion device at the firing port 9. The fire port 9 is provided with peat 13 to the combustion section 3.
It is also used when refilling.

Next, the configuration of the flame collecting section 5 will be described in detail below. The flame collecting part 5 has a circular flame through hole 6 penetrating vertically.
Is a ring-shaped member having a center at the center, and the flame collecting portion 5 is formed in a hat shape that is inclined downward over the entire circumference toward the outer edge side around the flame passage hole 6. It is. When the flame collecting portion 5 is installed in the inner peripheral wall 2, the flame collecting portion 5 has a convex shape along the inner peripheral surface of the inner peripheral wall 2 at a position higher than a position where the combustion portion 3 is installed. The metal fittings 7 are fixed at four positions maintaining 90 ° intervals, and the flame collecting part 5 is placed on each metal fitting 7 so that the combustion part 3
The flame collecting portion 5 is held by the outer peripheral edge portion 20 of the flame passage hole 6 at a position that vertically divides the space 4 in the inner peripheral wall 2.

By arranging the flame collecting portion 5 in the inner peripheral wall 2 as described above, first, as shown in FIG. 2, the flame generated in the combustion portion 3 hits the entire lower surface side of the flame collecting portion 5, and at this time, In addition, the flame rising along the inner peripheral wall 2 is blocked by the outer peripheral edge portion 20 of the flame passage hole 6 of the flame collecting section 5. The flame blocked by the flame collecting section 5 is received by the flame collecting section 5 along the lower end surface of the outer peripheral edge portion 20 toward the flame passage hole 6, and further,
The flame that has reached the flame holes 6 can pass through the flame holes 6 and intensively strike the center of the bottom of the large pot 15 held on the upper end side of the outer peripheral wall 1.

Further, by installing the flame collecting section 5 in the inner peripheral wall 2, the distance between the air intake hole 16 provided in the outer peripheral wall 1 and the combustion section 3 becomes longer. When the flame generated in the combustion part 3 or the flame once applied to the large pan further reaches the air intake hole 8,
The emission of the flame to the outside at the air intake hole 8 is reduced.
Further, by forming the space 17 between the outer peripheral wall 1 and the inner peripheral wall 2, unnecessary heat radiation to the outside of the combustion device is suppressed, and the heat retaining effect of the space 4 in the inner peripheral wall 2 is greatly improved. Thus, the combustion efficiency of the fuel is increased.
