Definitions

  • This invention relates to a spirit stove.
  • Such stoves are previously known and are preferably used as camping stoves, in yachts and caravans and for other purposes where electricity and LP-gas is missing or are unsuitable for other reasons.
  • pressure burners which are such burners where the fuel under pressure is distributed to several burner nozzles and pressure free burners where the fuel evaporates and burns from a free surface of the fuel container. Since the lastmentioned type of burner is a very simple construction it has been widly used and the present invention relates to such a burner.
  • a drawback with the lastmentioned type of burner is that it creates a comparatively high, open flame.
  • the existense of the flame causes, with the exception of the risk of a fire, that the heat energy available is not used particularly effectively since spill heat disappeares beside the pan which is placed above the flame.
  • a flame spreader being shaped as a shield with or without holes, above the burner so that the flame is divided into several minor flames which also means a better air supply to the combustion process. This arrangement does however not change the situation with regard to the loss of heat energy by spill heat.
  • a further drawback is that the pans being used become covered with soot from the flames.
  • camping stoves which are a combination of spirit burners and electrically heated stoves provided with a top, which is heated by electricity and which can be folded up in order to uncover a conventional spirit stove. These stoves are complicated and expensive.
  • the purpose of this invention is to achieve a simple spirit stove operating with a hidden flame thereby reducing the risk of setting fire to details in the surrounding and eliminating the creation of soot on the pans and to take care of as much as possible of the energy content of the flames and the fumes.
  • the spirit stove also has such a design that mainly no odour is created during burning of the spirit. Further the spirit stove operates with natural ventilation and without complicated means for directing fuel or air to the burner or for removing fumes from the burner. This is achieved because the device according to the invention has the characteristics mentioned in the claims.
  • Fig. 1 shows the front part of the stove as well as a vertical section through a spirit stove according to the invention whereas Fig. 2 is a vertical section on the line IIII in Fig. 1.
  • the Figures show a spirit stove for two hot plates which might differ from each other with respect to the size of the plates, the plates being placed on each side of the vertical middle line in Fig. 1.
  • the invention can however be used for any number of plates.
  • the stove comprises a box-like metal shell 10 the upper part of which is a top 11 having a higher edge part 12 and a lower central middle part 13.
  • the top is preferably of stainless steel but can also be manufactured by other metals, ceramic materials, glass and so on and has an opening 14 for a hot plate 15 which is fastened to the top by means of a steel ring 16.
  • the hot plate consists of a heat conducting material for instance cast iron and is at its bottom side provided with a projecting flange 17 which seen in a top view is U-shaped and directed so that the open part is directed towards the front.
  • the bottom side also is provided with an electric coil 18 which is connected to an electric circuit, not shown, in the stove to be supplied from an electric source.
  • two profiles 21 and 22 are provided serving as supports for a heat insulating insert 23.
  • This insert comprises two side walls 24 and 25 a front wall 26, a rear wall 27 and a roof part 28 surrounding an outer ring shaped, downwardly directed flange 29 of the plate 15.
  • the insert further has a rear opening 30 which is placed below several outlet openings 31 at the rear edge part of the top.
  • the stove further has a horizontal heat protection plate 32 below which a fuel container 33 for the spirit is placed.
  • the fuel container as usual comprises a closed circular metal shell enclosing a liquid absorbing mass.
  • the upper central part of the container which is surrounded by a ring shaped flange 34, is open so that the mass with the absorbed spirit is uncovered.
  • the flange 34 extends through a circular hole in the heat protection plate 32 so that the heat protection plate abuts the outer periphery of the flange.
  • a ring 35 is fixed concentric with the flange 34 the ring supporting a part of the burner comprising a holder 36 with a burner tube 37.
  • the holder comprises three S-shaped tounges applied about the ring 35 the tounges in their upper parts being joined to the burner tube which is directed vertically.
  • the burner tube 37 supports a flame spreader 38 by means of a U-shaped metal plate 39 which is fastened to the upper part of the burner tube.
  • the flame spreader is placed directly below the plate 15 and above the opening of the burner tube 40 and is shaped as a hat whose brim 41 is a heat reflecting part wheras the upper part of the hat has several holes 42 through which the flames are spread below the plate.
  • the spirit stove at its front wall 19 has a door 43 through which the fuel container can be removed in order to be filled.
  • the container is guided sideways by profiles 44 fastened to the shell 10 and being supported by a spring metal plate 45 with a rear bend 46 and a front projection 47 and a front bend 48 the rear bend 46 and the projection 47 being a stop means for the container 33 so that it can be fastened on the metal plate 45.
  • the front bend 48 serves as a handle by means of which the metal plate 45 and hence the container can be removed from the stove.
  • the metal plate is guided by means of a yoke shaped holder 49 fastened to the bottom of the shell 10.
  • the ring shaped flange 34 of the container supports a circular control and extinguishing plate 50 which has a somewhat larger diameter than the outer diameter of the flange 34.
  • the plate 50 can by means of an, in top view seen, angular arm 51 which is fastened centrally at the plate be moved continously from a position where it completely covers the opening within the ring shaped flange 34 to a position where the opening is completely uncovered. Thereby the plate is moved sideways between two of the tongues belonging to the holder 36.
  • the arm 51 is fastened for turning motions about a vertical shaft 52 fastened to the front part of the heat protection plate and has a front end 53 with which a control lever being shaped as a bar 54 cooperates, the bar being provided with a control means 55 which is placed at the edge part 12 of the top 11 and which can be moved manually along the front edge of the stove. Since the control means is turnably and slidably secured to a flange 56 at the front part of the stove movement of the control means 55 causes a corresponding turning motion of the extinguishing plate 50.
  • the stove also comprises an ignition device consisting of a knob 57 at the front wall of the stove the knob being secured to a shaft 58 which is turnably supported in a horizontal sleeve 59, the shaft supporting a notched wheel 60 at the burner tube.
  • a spark creating pin 61 is pressed towards the wheel by means of a spring, not shown, which is fastened in a tube 62 the tube and shaft being supported by a bracket 63 secured to the holder 36.
  • the spirit stove operates in the following way. Provided that there is fuel in the container 33 this fuel can be ignited by turning the knob 57. A spark is created by the motion between the notched wheel 60 and the pin 61. This spark falls down into the opening within the annular flange 34 of the container 33 provided the extinguishing plate has been removed by means of the control means 55. The fuel is ignited and combustion air is thereby sucked through the openings 64 and through the holder 36 into the burner tube 37 whereby flames blow up through the holes 42 of the flame spreader 38. Secondary air at the same time enters freely through the air-inlet openings 64 to all parts of the flames around the burner tube 27 and to the area between the flame spreader 38 and the hot plate 15 or the insert 23.
  • the size of the flame can be controlled. Because of the existense of the flange 17 the hot fumes are first directed forwards below the hot plate 15 after which they are deflected rearwards about the front edges of the flange 17 and flow between the outside of the flange 17 and the flange 29 and the insert 23 towards the rear edge of the hot plate where the fumes leave through the opening 30 of the insert and further through the outlet openings 31 of the top.
  • the purpose of the insert 23 is to prevent that heat from the flames is transmitted to the top and to concentrate the heat energy from the flames to the hot plate. It has turned out that when the heat insulating material in the insert has reached a certain temperature and the heat transmission between the flames and the surrounding insert decreases the flames are deflected towards the bottom side of the hot plate thereby increasing the heat exchange with it.
