DE3128298A1 - Small stove for field use - Google Patents

Abstract

The invention relates to a small stove which can be set up in the open and which consists of thin sheet metal which is first packed as a flat pack for transport. The sheet metal is bent to form a round or oval casing and the folded sides are hooked into one another so that a casing is produced which is erected upright on the ground. Small holes or sheet-metal flaps are punched into this casing, on which or into which the ends of a fire grate plate are placed. <IMAGE>

Description

Xleinofen for field use

The invention relates to a small furnace for preferably solid fuels and for use outdoors, the invention is based on the object of a @ from a few individual parts easy to assemble and easy to transport To create furnace.

This object is achieved in that the furnace consists of a thin jacket sheet that to the Zwedce des Transporbes with further items to a flat one Package is packed and that is loosely folded in opposite directions on the shorter sides and that is parallel to the edge of the tang and a little away from the long side with small holes or contains punched and bent out or welded sheets and when erected Oven this jacket sheet is bent into a round or oval jacket and then folded Pages are hooked into each other and in the small holes or on the protruding ones small sheet metal a fire grate that fills the cross-section of the jacket of the stove is engaged or placed.

The furnace is thereby improved and the outer jacket is in front of a too high temperature is preserved by placing the furnace on the grate plate one in height and diameter w compared to the jacket of the stove, smaller Sheet metal cylinder with punched spacers bent towards the jacket of the furnace is put on.

It is appropriate and necessary for the air supply that the Lower edge of the mantle feet, e.g. B. designed as an angle, are attached so that a gap of at least 10 mm remains between the lower edge and the floor, The oven is particularly good for cooking because the top surface or a significant part of it is formed by a pot that is in the upper area surrounded by a flange and placed on the edge of the shell of the furnace or on intermediate Rings is placed.

An exemplary embodiment is described in more detail with the aid of FIGS. 1 and 2, The furnace has a circular or oval cross-section, which is dismantled into individual parts The prefabricated small oven is initially transported as a flat package. The flat outer jacket shows on his Ehden folded edges that are arranged in opposite directions and that are suitable manual rounding of the jacket sheet to a cylinder or an oval without Use of auxiliary tools with its folded edges to be hooked into one another and the rebate edges are held together due to the elasticity of the material, Dar Of @ nmantel 1 wriat prepunched punching marks 3, the orthogonally inward be bent pointing and thus form the support for the combustion plate 4, After inserting the grate plate 4, the final cross-sectional shape is achieved formed and the folded edges 2 are secured against unhooking.

At the lower end of the furnace shell 1, the standing brackets 5 are hooked into place or, riveted that an air ring space 6 is formed in the lower area, which is used for It is necessary to maintain the combustion air, the grate plate 4 has a hole pattern over which a coaxially arranged round slide 7 is provided is that by rotating the initially congruent hole pattern for complete coverage brings and thus a control of the combustion process he enables. Farther is above the grate plate 4 a Sheet metal cylinder 8 inserted, the orthogonally exposed punch marks 3 have an annular space 9 between the outer jacket and inserted, manually deformed cylinder 8, through which cooling air flows and to the extent that a reduction in thermal radiation is achieved.

Another protection against thermal radiation can be achieved by using of a material with low radiation intensity can be achieved. The outer cylinder 1 finally receives a ring attachment 10 for receiving a water basin 11, whose bottom is shaped so that it protrudes so far into the combustion chamber that an optimal heat transfer can take place.

This small furnace is dismantled in the opposite way, see above that after dismantling, a transport as a flat package with the least possible Packaging volume can take place. Blank page

Claims (3)

Claims 1. Small stove for preferably solid fuels and for outdoor use, characterized in that it consists of a thin sheet metal jacket consists, which for the purpose of transport with other items to a flat Package is packed and that is loosely folded in opposite directions on the shorter sides and the small holes parallel to the longitudinal edge or slightly removed from the long side contains punched and bent out or welded sheets and when erected Oven this jacket sheet is bent into a round or oval jacket and then folded Pages are hooked into each other and in the small holes or on the protruding ones small metal sheets a fire grate that fills the cross-section of the shell of the furnace, is engaged or placed. 2. Small oven according to claim 1, characterized in that when erected Oven on the grate plate one in and in diameter compared to the mantle of the furnace, smaller sheet metal cylinder with punched out bent towards the jacket of the furnace Spacers is placed, 3. Small furnace according to claims 1 and 2, thereby characterized in that at the lower edge of the shell, troughs, z, B, are formed as angles, are fixed in such a way that there is at least 10 mm between the lower edge and the floor wide gap remains. 4, xlein oven according to claims 1 to 3, characterized in that that the top surface, or a significant part of it, is formed by a pot, which is surrounded by a flange in the upper area and on the edge of the jacket of the furnace or on rings inserted between them.
