[Problems to be solved by the device]

 However, the above-mentioned conventional portable cooking furnace has the following problems. (1) Although handy equipment is required for picnics in the suburbs, conventional portable cooking furnaces are bulky and bulky when transported because the furnace body is an integrally molded box shape. (2) Handles, supporting legs, etc. are fixed to the furnace body of the conventional cooking furnace, but the structural parts are complicated, such as the bent shape of wire steel, and the mounting work such as welding is troublesome. The manufacturing operation requires a long time and the manufacturing cost becomes high.

The present invention solves the above-mentioned problems and makes it easy to carry without being bulky when not in use, and allows easy assembling at the time of use. The purpose of the present invention is to provide a portable cooking furnace which can be manufactured by the one-punch molding machine of (1) to simplify the manufacturing process to improve productivity and manufacture products at low cost.

Further, according to the present invention, by adjusting the cut-and-raised angle of the cut-and-raised piece on the bottom surface of the cooking furnace, the ventilation amount of the ventilation hole can be freely adjusted, and the heating power can be easily adjusted. The purpose is to provide a cooking oven for cooking.

Further, in the present invention, the front and rear plates are formed so that their heights are higher than those of the left and right side plates, and the net-mounting tongues bent and projected inward are the upper ends of the left and right side plates. It is an object of the present invention to provide a portable cooking oven which is formed so as to be located above.

[0007]

[Means for Solving the Problems]

 In the portable cooking furnace according to the invention of claim 1, the four corners of the rectangular metal plate are cut off leaving the engaging projections, respectively, and a plurality of ellipses are arranged at regular intervals along the fold line connecting the four corners. -Shaped through holes are formed, the front, rear and left and right side plates are bent along the fold line to stand upright on the bottom plate to form the furnace body with the upper opening, and the front, rear and left plates are formed. Each of the right side plates is provided with a circular hole for supplying air, and the front and rear plates are provided with a handle that can be cut and raised outward through a connecting portion and a mesh mount that can be bent and projected inward. A tongue piece is formed on the bottom plate, and a pair of cut-and-raised legs formed by cutting and raising the bottom plate in the vicinity of each of the four corners, and a vent hole formed by the cut-and-raised piece of the bottom plate. The ventilation amount from the ventilation hole can be adjusted according to the cutting and raising angle of the cut and raised piece. Than it is.

According to a second aspect of the present invention, in the portable cooking furnace according to the first aspect, the front and rear plates are formed such that their heights are higher than those of the left and right side plates, and the nets are bent and projected inward. The mounting tongue is formed so as to be located above the upper ends of the left and right side plates.

[0009]

[Embodiment of device]

 Embodiments of the present invention will be described below with reference to FIGS. 2 and 3, 10 is a flat rectangular metal plate such as an iron plate, and the four corners 11a to 11d of the metal plate 10 are opposed to each other except for the engaging projections 13a and 14a. When the two members are cut so that the angle formed by them is an acute angle, the cutting length of the left and right side plates 13, 13 on one side is shorter than the cutting length of the front and back plates 14, 14 on the other side. It has been cut to size.

Reference numeral 15 denotes an elliptical through hole having a major axis along an upward direction of a polygonal line 16 connecting the cutting vertices 12 of the four corners 11a to 11d, and a plurality of continuous through holes are formed at regular intervals. There is. A plurality of round holes 17 for air supply are formed in the front and rear plates 14 and 14 and the left and right plates 13 and 13. Reference numeral 18 denotes a handle formed by cutting portions 19a and 19b that are long and cut in the left and right directions in a substantially U-shaped configuration in the center of the front and rear plates 14 and 14. The handle 18 is a non-cutting portion during assembly. It is used when the furnace body 30 is moved as the handle 18 by standing up to the outside through a certain connecting portion 20.

Reference numerals 21 and 21 denote net-mounting tongue pieces for net-mounting, each of which is formed by a cut portion 19 b cut into two strips formed on the front and rear plates 14 and 14, respectively. Can be easily erected facing the inner surface side of the furnace body 30 by means of the small elliptical through holes 22 formed between the connecting portions 20 of the handle 18. Reference numeral 23 is a bottom plate, and the front and rear plates 14 and 14 of the bottom plate 23 are adjacent to the left and right plates 13 and 13 and are formed by a pair of cut portions 24a and 24b cut in a U-shape. Legs 25, 25 are provided respectively.

Reference numeral 26 is a cut-and-raised piece formed by a cut portion 27 which is cut long in the left and right directions. By adjusting the cut-and-raised angle of the cut-and-raised piece 26, the opening size of the vent hole 28 is adjusted. It is possible to adjust the air flow rate into the furnace body by changing the height.

As described above, the four corners 11 formed on the metal plate 10 of the present invention are cut off, the shape of the round hole 17 for supplying air, the elliptical through hole 15 on the folding line 16, the net-mounting tongue piece 21. The small elliptical through hole 22 for bending the handle, the handle 18, the leg 25, and the cut-and-cut portions 19a, 19b, 24a, 24b, 27 for forming the cut-and-raised piece 26 are formed by one punch molding. Formed by the machine.

In order to use the portable cooking furnace according to the above-described embodiment of the present invention, as shown in FIG. 4, the front and rear plates 14, 14 and the left and right side plates 13, 13 are connected via the fold line 16. Bending inward while standing up, with the front and rear plates 14 and 14 and the left and right side plates 13 and 13 cut end surfaces 13b and 14b in contact with each other, the engaging projections 13a of the left and right side plates 13 are moved forward. The furnace body 30 is constructed by bending and locking the rear plate 14 on the outer surface side, and bending and locking the engaging projections 14a of the front and rear plates 14 on the outer surface side of the left and right plates 13, respectively. It

Next, the handle 18 formed by the two notches formed on the front and rear plates 14, 14 is cut and raised to the outer surface side to be in a horizontal state, and the leg portions 25. located at the four corners of the bottom plate 23. Cut and raise 25 to stand on the ground. Further, the cut-and-raised pieces 26 formed on the bottom plate 23 limit the cut-and-raised angle depending on the amount of ventilation, and make the opening of the ventilation hole 28 a desired size to adjust the ventilation.

In cooking, a heat source such as charcoal fire (not shown) is arranged on the bottom plate 23, a wire net or the like is placed on the upper end surfaces 13c of the left and right side plates 13, 13, and meat and vegetables are placed on the wire net. Put on a dish and cook. Further, when the heat power is too strong, a wire mesh can be placed on the tongue pieces 21 facing the front and rear plates 14 and 14 on the inner surface side to separate from the heat power source.

Further, at the end of cooking, after removing the heat source, the furnace body can be operated as a flat rectangular metal sheet 10 in the reverse manner of assembling to facilitate portability. It

In the above-described embodiment, the four corners 11 of the metal plate 10 are cut so that the angles formed by the cut end surfaces are cut to form an acute angle, and the upper surface opening portion at the time of assembling the furnace body 30 is cut. The shape of the inverted trapezoid is larger than the area of the bottom plate 23. However, it is needless to say that the rectangular parallelepiped shape may be obtained by cutting so that the angle becomes a right angle.

[0019]

[Effect of device]
