Definitions
- the invention relates to a firing insert for a cooking device, in particular a mobile field kitchen, which consists of a transportable frame with cooking vessels or holders therefor and an underlying combustion chamber.
- Cooking devices of this type are used extensively by the military and aid agencies in order to be able to prepare hot meals at any point, predominantly outdoors.
- Burning inserts which work with liquid or gaseous fuels are often provided as burners. Both the burners and the storage containers, i.e. Tanks or gas bottles, arranged within a removable insert.
- Such combustion units are frequently too susceptible to malfunction for the practical use of such cooking appliances and, particularly in the case of a narrow spatial arrangement within the insert, are also not entirely harmless, for example in gasoline-powered burners.
- the object of the invention is to provide a burning insert for a cooking device, in particular a mobile field kitchen, which is particularly simple, robust and not susceptible to faults, maintenance-free and simple and sensible to use, and can be used with easily stored and transportable fuel materials.
- a combustion insert with a receiving shell for several dry fuel bodies, which is ventilated and arranged on a frame and can be removed from the combustion chamber.
- the entire firing insert which, for example, consists of the gas bottles with pressure regulator, burner nozzles and possibly ignition device in a liquid gas-operated cooking appliance, can thus be made from a relatively simple sheet metal part, which can also be inserted instead of the other firing insert in cooking appliances designed for other burners.
- the dry fuel used is the dry fuel, often incorrectly referred to as dry alcohol, in the form of a mostly white solid or sugar-like solid, how it has been manufactured and sold by the applicant under the name "Esbit" for decades. This dry fuel would be shaped when used in larger cooking appliances, for example field kitchens, preferably in the form of a cube with an edge length of approximately 10 cm, and burns practically without residue with a spirit-like blue, non-sooting or smoking flame.
- the fuel is particularly light and can be stored and transported in a small space and has a very high calorific value per unit weight and space, which is on the order of the best coal. It is therefore ideal for storage, distribution and transport, clean in use, and the stock, both outside and inside the combustion chamber, can always be easily surveyed.
- cookers for emergency catering and bivouac operated with such dry fuel have been known for a long time. These are mostly collapsible stoves, in whose collapsible sheet metal frame a support surface for the dry fuel body is integrated.
- the combustion insert within the combustion chamber can be charged from the outside with individual dry fuel bodies, which preferably have the same shape, namely mostly cube shape. This also allows regulation to the extent necessary, since dry fuel bodies can also be removed individually and easily extinguished.
- the receiving shell can preferably be designed to receive a plurality of dry fuel bodies in a row. In addition to good accessibility for the combustion itself, this also enables a clear arrangement.
- a perforated support for the dry fuel body can preferably be arranged in the receiving shell. It can preferably be arranged so high that the lower edge of the dry fuel body is almost no longer covered by the side walls of the receiving shell in order to keep the sides accessible to the combustion air. Nevertheless, the small amounts of liquid intermediate products can run into the receptacle and burn from there again. The resulting intermediate air layer also creates additional ventilation.
- the support is not actually a grate through which combustion air flows upwards, but rather a permeable support.
- the receiving shell or the support can preferably have a division on which the dry fuel bodies can be arranged at a certain distance from one another. On the one hand, this ensures that the gasification of the fuel can also occur in the area between two dry fuel bodies and thus a largely uniform combustion begins around the body, and on the other hand, the bodies are more easily accessible for replacement and possibly extinguishing.
- the burning insert can advantageously be designed such that the flat, elongated rectangular receiving shell on its long sides preferably has obliquely outward and downward-pointing support struts which are bent on its lower edge and which may be broken.
- Such a burning insert which is easy to produce from sheet metal is stable and ensures the basic conditions described above.
- the cooking appliance can be provided with releasable fastening devices which interact with the firing insert for the firing insert. This is particularly important in a mobile field kitchen so that the firing insert is safely stored even when it is shaken. Since it is often required that cooking should also be possible while driving, a perforated, air- and flame-permeable safety cage, each surrounding at least one dry fuel body, can advantageously be provided, which is fixed with brackets on the burning insert or cooking appliance. Such a cage, which can also surround the entire receptacle at the height corresponding to the original height of the dry fuel body, prevents the dry fuel body from jumping out of the insert when driving, especially when it burns. Nevertheless, the cage, which preferably consists of a strong wire mesh, hardly prevents gasification and flame development.
- At least one cover that can be brought over at least one dry fuel body can be provided, which essentially seals the entire outer surface of the dry fuel body except for its contact surface on the receiving shell or the support.
- a plurality of covers can preferably be formed for each individual dry fuel body in a row.
- the complete sealing of the dry fuel body on its gasification surfaces (upper surface and side surfaces) means that it is extinguished without further gasification, consumption and the generation of disruptive exhaust gases. It is therefore possible, for example when five dry fuel cubes are arranged in a row, to carry out a five-stage regulation by covering the individual cubes without interrupting operation.
- the cover can preferably be a sheet metal box which is open on one side and has a holder for an operating device on the opposite side.
- This holder can advantageously be a bow that is open on both sides and covers a box side.
- the bracket therefore has the size of the base surface of the cover, and a slot is formed between it and the upper box surface, into which a spatula-like tool with a handle and a handle can preferably be inserted as the operating device.
- the working surface of the operating device is designed on the one hand for insertion into the holder of the cover, but on the other hand also for receiving a dry fuel body which can be handled from the outside in order to load or remove it.
- the working surface in the direction of the handle is preferably limited by a stop.
- a cooking device 11 which is normally referred to as a field kitchen. It has a chassis or frame 13 with wheels 12 which contains a combustion chamber 14 which heats a hotplate 15 on which cooking vessels 16 can stand.
- the combustion chamber normally has combustion chamber doors (not shown), inlet and outlet openings and possibly a chimney.
- directly heated cooking vessels can also be provided or, as indicated by dashed lines, the cooking vessels can be held in depressions in the hotplate.
- Fastening devices 17 in the form of longitudinal guide rails are provided on the bottom of the combustion chamber and are used for the removable attachment of a combustion insert 18.
- These brackets can be of any design and can also be different in the case of different cooking devices, so that adapters can optionally be interposed for the same firing insert.
- the burner insert 18 is removably held in the fastening devices 17. It is shown in detail in FIG. 2. It consists of sheet metal and has a flat, elongated rectangular receiving shell 20 with a circumferential edge 21, which is optionally beveled on one end face for better removal of a dry fuel body. that have multiple openings 23. On their lower edge, the support struts 22 are provided with bevels 24 which on the one hand form standing surfaces and on the other hand form rails which interact with the fastening devices 17.
- a support 25 which consists of a perforated, for example perforated sheet metal with an edge 26 bent downwards, which stands on the bottom of the receiving shell 20, so that the flat part of the support is an openwork, at some distance from the floor 27 of the receptacle located support surface forms.
- dry fuel bodies 28 which are cube-shaped and have a side length of approx. 10 cm. The material of this dry fuel corresponds to the material marketed by the applicant under the trademark "Esbit".
- Fig. 2 From Fig. 2 it can be seen that several equally large and equally shaped dry fuel bodies of this quite considerable size of 1000 cm 3 content are arranged in a row on the burning insert, each with a distance 29 from each other.
- the exact arrangement and the distance 29 can be ensured by a division on the receiving shell or the support, for example, as indicated by dashed lines, by inwardly directed bulges 30 in the longitudinal edge 21 of the receiving shell 20 or by corresponding cams or elevations in the support 25.
- An operating device 32 which has the shape of a spatula or a flat scoop with an essentially flat working surface 33, a handle 34 and a handle 35, is used to apply the dry fuel bodies, also for refilling during operation.
- the working surface 33 is somewhat longer and approximately as wide as a side edge of a dry fuel body 28. From FIG.
- this operating device 32 also serves a second purpose, namely for positioning and removing a cover 38. It consists of a body in the form of a dry fuel body 28 adapted tin box, which in the present case is almost cube-shaped and whose lower side is open. The dimensions are slightly larger than that of the dry fuel body in its original size.
- a bracket 40 Parallel to the upper wall 39 of the cover is a bracket 40 which occupies the entire surface of the upper wall 39, but is arranged at a short distance therefrom, so that there is a narrow space open on two sides into which the working surface 33 of the Operating device 32 can be pushed in and is securely guided there.
- the stop 36 ensures correct positioning.
- a securing cage can be provided which surrounds individual or all of the dry fuel bodies 28 of a row during the burning process.
- This protective cage 40 consists of a wide-meshed wire mesh, which is mounted so firmly on the insert, for example, by laterally projecting pins 42 which can be latched into openings 41 in the edge 21 of the receiving shell 20, that a dry fuel body 28 even when shaken, for example when the cooking appliance 11 is being transported , cannot jump off the insert.
- the protective cage 40 should be dimensioned and arranged so that the cover 38 can still be placed over it.
