Definitions

  • the invention relates to a wood-burning stove, consisting of a combustion chamber, a cooking vessel stand arranged above it and a jacket at least partially enveloping a cooking vessel and the combustion chamber.
  • Such cooking vessels are known, for example, in the form of converted color bottles.
  • Population groups in underdeveloped countries use them to prepare hot meals in order to make better use of the firewood compared to the open fire.
  • the procurement of firewood in particular often involves considerable effort in climate zones that border the desert.
  • the object of the invention is to provide a wood-saving stove which can be transported inexpensively even to the most distant corners of the earth and which enables residents in areas with little wood to further increase the utilization of the firewood.
  • the invention is based on the object of making the furnace available to the interested population at the lowest possible cost.
  • FIG. 1 shows a schematic vertical section through a first embodiment of the wood-saving stove according to the invention
  • FIG. 2 sheet metal blanks of individual parts of the wood-saving stove according to the first embodiment
  • FIG. 3 further sheet metal blanks of the wood-saving stove according to the invention in accordance with the first embodiment
  • FIG. 4 shows a schematic vertical section through a second embodiment of the wood-saving stove according to the invention

  • Figure 11 is a sheet metal blank of the inner shell and Figure 12 sheet blanks of the combustion chamber.
  • FIG. 1 shows the vertical section through the wood-saving stove 1 according to the invention.
  • the outer periphery of the wood-saving stove is formed by jacket 5. This is divided into an upper jacket 6 and a lower jacket 7.
  • the lower jacket part 7 is closed at the bottom by means of a bottom 9.
  • the upper end forms the partition plate 10, in which the combustion chamber 2 is suspended.
  • the combustion chamber 2 is used to burn small logs 31.
  • the necessary combustion air flows from the outside through the air inlet openings 8 provided in the lower jacket 7. In this case, it is first directed downward by the air baffles 11, 12 in accordance with the interrupted supply air flow 30. Part of the air flows through the purge air opening 29 in the air baffle 12 in order to avoid stable air stratification there. When the air baffles flow around, the supply air heats up. It then enters the combustion chamber 2 from the side and from below.
  • the logs 31 are initially held on the grate 32 until complete combustion, which preferably consists of individual rods in the form of threaded rods.
  • the air baffles 11, 12 are also fastened to the partition plate 10 by means of threaded rods, the ends of which extend beyond the partition plate 10, the projecting ends forming the cooking vessel stand 3. This supports the cooking vessel 4.
  • a piece of wood feed 13 is used, which is designed to be horizontally pivotable so that the loosely suspended combustion chamber 2 can be removed from the lower part of the furnace.
  • the piece of wood feed 13 thus forms an opening in the wall of the upper casing 6.
  • the upper casing part 6 can be closed by a cover 15, which serves as a pan to increase the utility value 16 is formed.
  • the exhaust air leaves the furnace through exhaust air outlet openings 14, which are formed as bulges of the upper edge of the upper jacket. This flows around the pan 16 from below by the warm exhaust air, so that there is a surprisingly good heat transfer.
  • the wood-saving stove according to the invention can be easily assembled from individual sheet metal blanks according to FIGS. 2 and 3 with the aid of additional screws and nuts without essential additional tools by laypersons.
  • the sheet metal blanks have surprisingly little waste and can be put together particularly tightly in a shipping unit which, compared to the prior art, causes significantly lower production and transportation costs.
  • the furnace itself has a hexagonal base surface 28, which is almost free of waste by suitable manufacturing processes, e.g. B. can be produced by punching as sheet metal blank 17, from which the subsequent bottom 9 is then formed. For this purpose, only the tabs 33 on the fold lines 34 have to be bent vertically upwards.
  • the lower jacket part 7 is formed from the sheet metal blanks 18 and 19.
  • These blanks are also to be folded on the fold lines 34 in accordance with the hexagonal shape.
  • the mounting openings 35 are used to insert screws in order to screw the blanks to tabs of the other sheet metal blanks with the aid of nuts.
  • the sheet metal blanks 20 and 21 are attached to the sheet metal blank 22, which forms the separating sheet 10, as air baffles 11 and 12 by using the mounting openings 36 in the sheet metal blank 22.
  • the screws protrude beyond the surface of the separating plate 10 and form that which is not visible in FIG. 2
  • Cooking vessel uprising 3 ( Figure 1).
  • the air inlet openings 8 are provided in the upper edge region in the sheet metal blanks 18 and 19, as are the purge air openings 29 in the sheet metal blank 21 of the air baffle plate 12.
  • the piece of wood feed 13 is formed from the sheet metal blank 24. This is pivotally attached to the bore 37 by means of screws on the partition plate 10. It pierces an opening in the jacket 6 formed by notches 38 in the blank 25.
  • the combustion chamber 2 is bent from two sheet metal blanks 23 by corresponding edges on the fold lines 34 to form two U-shaped parts, from which the combustion chamber is then assembled.
  • the sheet metal blank 26 forms the lid 15 or the pan 16, which can be moved by means of the sheet metal blank 27, which takes over the function of the handle.
  • Sheet metal blank 25 is used to form the upper jacket 6.
  • the exhaust air outlet openings 14 are formed on the upper edge in the form of bulges.
  • FIGS. 4 to 11 show a second preferred embodiment of the wood-saving stove according to the invention.
  • the vertical section according to FIG. 4 shows the structure schematically.
  • the jacket 5 is formed in one piece.
  • the cooking vessel stand 3 which consists of the shaft of screws, supports the cooking vessel 4, the upper edge 43 of which is shaped as a collar 44.
  • the plaintive 44 is supported on the upper edge of the jacket part 6.
  • the collar 44 is so wide that the cooking vessel 4 can be conveniently lifted out of the upper jacket part 6.
  • the outer jacket 5 heats up only slightly, so that it can also be touched safely. This advantageously prevents burns.
  • the inner jacket 42 is firmly connected to the jacket 5 by means of rivets 46.
  • the separating plate 10 has tabs 50 on the outer edge, which are likewise firmly connected to the jacket 5 by means of rivets.
  • the combustion chamber 2 is suspended in the partition plate 10. Its bottom 45 is formed by folded extensions of the side walls. The two parts of the floor 45 are inclined to one another so that the fire slides towards the center.
  • the hexagonal plan of the wood-burning stove can be seen. This shape can be produced particularly easily by edging the sheet metal blanks.
  • the combustion chamber 2 with its rectangular outline is arranged in the cover plate 10 in such a way that the corner 49 of the combustion chamber 2 lies opposite the center of an outer surface of the hexagonal shell 5. As a result, the distance to the piece of wood feed 13 is particularly small.
  • the jacket 5 is formed by two sheet metal blanks 47 and 48.
  • an exhaust gas collecting pipe 41 can be provided, which enables a connection to the chimney of a house, as is shown in the perspective illustration of the wood-saving stove in FIG. 6.
  • Figure 7 shows a view of the wood-saving stove from the front.
  • FIGS. 8 to 12 essentially show the sheet metal blanks.
  • the two sheet metal blanks 47 and 48 form the casing 5 after edges and joining.
  • FIG. 9 shows the sheet metal cutting of the separating plate 10 with outer tabs 50. The tabs are bent at right angles before joining.
  • the hexagonal shape of the wood-saving stove results in an advantageously small amount of waste, as is shown, for example, in FIG. 10 on the basis of a cutting pattern for partition plate 10 from a sheet metal plate 53.
  • the sheet metal blank shown in FIG. 11 for the inner sheath 42 also has little waste.
  • a wood-saving stove is made available for the first time, which can be transported inexpensively even to the most remote parts of the world and can be easily assembled by inexperienced and inexperienced laymen without the help of special tools. In the corresponding climatic zones, it can help alleviate the wood shortage, since it uses the little available firewood about twice as well as stoves according to the state of the art.
