Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a furnace used mainly for cooking rice outdoors.

(Prior art) Conventional ovens for outdoor cooking have a cylindrical oven body with a fire outlet at the lower front, a smoke exhaust outlet at the upper rear, and a fire grate at the bottom of the oven body. generally known.

(Problems to be solved by the invention) However, since the body of the above-mentioned furnace cannot be separated, it is not only bulky to store and transport, but also because the distance between the grate and the opening at the top is constant. Although it was possible to boil fish in a pot, it was not possible to roast fish and meat. On the other hand, portable stoves can be disassembled by fitting the lower end of the upper frame to the upper edge of the lower frame with a wooden base to form a body, and a fire pan is fitted to the upper frame of the body. Although it is described in Japanese Utility Model Publication No. 30-4273, it does not have a fire spout or smoke exhaust port and is used on a tabletop using charcoal as fuel in a grate, so it cannot be used outdoors with firewood or other fuel. It is not suitable for cooking rice in a pot, is not easy to disassemble and assemble, and requires a fire pan, which increases production costs.

(Means for Solving the Problems) The present invention relates to a furnace that solves the above-mentioned problems, and includes a metal plate having a notch for forming a combustion opening on the lower edge of the front surface and a smoke exhaust port on the upper rear surface. A cylindrical upper body made of a cylindrical upper body, and a lower body whose diameter can be freely expanded, which is made of an elastic metal plate curved to approximately the same diameter as the upper body while leaving a gap of the same width as the notch of the upper body on the front side. The lower edge of the upper body is received by a plurality of receiving pawls disposed at the inner upper end of the body to provide a furnace body which is removably connected and has an upper and lower gap with the notch to form a stove; The furnace is characterized in that a separate grate with legs is arranged in the lower body of the furnace body.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

Reference numeral 1 denotes a cylindrical upper body made of a heat-resistant metal plate such as a steel plate, and the upper body 1 has a notch 2a for forming a fire opening on the lower edge of its front surface, and a punching molding on the upper rear surface. Smoke exhaust port 3 consisting of a plurality of circular holes
is provided. 4 is a notch 2a in the upper body 1
The lower fuselage is made of an elastic metal plate such as a steel band, which is curved to have approximately the same diameter as the upper fuselage 1, leaving a gap 2b of the same width on the front surface, and the lower fuselage is free to expand its diameter. Further, the lower body 4 is approximately the same height as the upper body 1, and a plurality of claw receiving portions 5 are provided at the inner upper end thereof. The upper body 1 and the lower body 4 are removably connected by having the lower edge of the upper body 1 received by the catch portion 5 of the lower body 4, so that the notch 2a and the interval 2b are vertically aligned. A furnace body 6 is formed with a fire spout 2, and a separate fire grate 7 with legs is arranged in a lower body 4 of the furnace body 6. In addition, in the figure, 8 is the upper body 1
With a ring that fits into the upper opening of the pot,
This is convenient for hanging a pot or the like, and a shape-retaining ring may also be removably fitted to the lower end of the lower body portion 4, although not shown.

A device configured in this way usually has an upper torso 1
You can hang a pot, kettle, etc. through the opening at the top of the notch 2.
Fuel such as firewood is put into a grate 7 with legs arranged separately in the lower body 4 of the furnace main body 6 through a fire opening 2 formed by vertically forming a space 2b between a and a distance 2b, and this fuel is ignited. If it is burned on the grate 7, the flame will flow toward the smoke exhaust port 3 provided on the upper rear surface of the upper body 1 under sufficient air supply flowing in from the fire port 2.
Pots, pots, etc. are things that heat efficiently. Furthermore, the furnace body 6 is made by detachably connecting the upper body 1 and the lower body 4, and the grate 7 is connected to the lower body 4.
In the case of a barbecue in which charcoal is brought close to the food to be cooked, the upper body 1 is placed in a plurality of receivers at the inner upper end of the lower body 4 whose lower edge is received. If the upper body 1 is separated from the claw part 5, and the grate 7 is positioned at the center of the lower end of the upper body 1 as shown in FIG. It can be used smoothly as a barbecue stove under the supply of air from the notch 2a provided on the rim for forming a fire pit. Furthermore, a notch 2 in the upper fuselage 1 made of a metal plate is provided.
The upper fuselage 1 is left with a gap 2b of the same width as a on the front surface.
The lower body 4, which is made of an elastic metal plate curved to approximately the same diameter as the diameter, can freely expand its diameter by using the gap 2b. As shown in Figure 3, the lower body 4, which has a claw receiving part 5 on the inner upper end, can be easily stacked on the outside of the upper body 1, and can be packed without being bulky. If the lower body 4 is of the same height, it can be packed even more compactly.

(Effects of the invention) As is clear from the explanation of the above embodiments, the present invention has a unique structure of an upper body made of a metal plate and a freely expandable lower body made of an elastic metal plate, which can be attached and detached. By connecting them together, they can be conveniently used not only as a stove but also as a barbecue stove, and can be packed compactly without being bulky for storage and transportation, eliminating the problems of conventional stoves. It has extremely great practical value.
