Definitions

  • the present invention relates to a portable fireplace, the barrel-shaped body of which is preferably designed as a beer keg.
  • fireplaces are already known from practice, such as simple fire bowls or fireplaces that use a disused washing machine drum as a combustion chamber.
  • these fireplaces exist in different variations, they are usually only intended for a fixed location. If they do have to be transported, they have the disadvantage that they are quite large and heavy, which makes transport considerably more difficult.
  • the dismantling of the fireplaces for transport is usually time-consuming and complex, with additional tools being required.
  • Such fireplaces are not designed for multiple transport. As a rule, such fireplaces are handcrafted products that are only produced in small numbers and are therefore expensive.
  • an object of the present invention is to provide a fireplace which enables simple assembly and disassembly and which can be easily and frequently transported in a compact state.
  • the transportable fireplace according to the invention comprises a barrel-shaped base body, which on its first end face, which is the upper side of the base body in the operating state represents, has a smoke extraction opening. Furthermore, the base body has several air inlet openings on its circumference, so that the fuel, preferably wood, is supplied with enough ambient air with oxygen. Furthermore, the base body has at least three foot receptacles on its second end face, which in the operating state represents the underside of the base body.
  • a connection ring is arranged on the smoke extraction opening of the base body, to which a first smoke extraction pipe can be attached with its first end.
  • the outer diameter of the first smoke exhaust pipe is smaller than the inside diameter of the smoke exhaust opening.
  • the transportable fireplace has a second smoke exhaust pipe, which can be attached with its first end to the second end of the first smoke exhaust pipe.
  • the outer diameter of the second smoke outlet pipe is selected to be smaller than the inner diameter of the first smoke outlet pipe, so that the second smoke outlet pipe can be lowered at least in sections into the first smoke outlet pipe for the production of the transport state.
  • the transportable fireplace has at least three feet, which can be detachably attached to the foot receptacles of the base body.
  • the feet are attached in order to achieve a heat-insulating distance between the underside of the base body and the floor space.
  • the feet are instead dismantled and preferably stowed in the base body or in the second discharge pipe.
  • the barrel-shaped base body is particularly preferably made from a stainless steel beer keg of the KEG-50 DIN type.
  • This can be purchased inexpensively due to the large number of pieces and, with its 50 liter capacity, offers a suitable basic body for the transportable fireplace. It has also been shown that the inherently high stability of the stainless steel beer kegs manufactured according to KEG-50 DIN is sufficient, even at the high temperatures that occur when burning wood inside the base body, to avoid excessive deformation of the material , so that the fireplace remains operational over many usage cycles.
  • the material of the KEG-50 DIN beer kegs is also non-rusting and withstands the usual environmental influences for a long time. All other components of the hearth are preferably also made of stainless steel.
  • the barrel-shaped base body, the first smoke outlet pipe and the second smoke outlet pipe preferably have essentially the same length, so that the two smoke outlet pipes can be lowered almost completely into the barrel-shaped base body in order to put the fireplace in the transport state. This offers a compact transport size and makes it easy to stow in a transport vehicle.
  • the at least three feet preferably have a length of 20 ⁇ 5 cm, the circumference of the at least three feet is particularly preferably smaller than the inner diameter of the second smoke exhaust pipe, so that the at least three feet can be stowed inside the second smoke exhaust pipe for transport.
  • the barrel-shaped body, the connection ring, the first smoke outlet pipe and the second smoke outlet pipe are preferably arranged coaxially with one another, ie the The smoke extraction opening of the base body is arranged centrally on its first end face.
  • the at least three feet can preferably be attached to the foot receptacles with a thread, by means of a bayonet catch or a similar simple connection arrangement. This has the advantage of quick and safe assembly/disassembly, preferably without the use of tools.
  • connection ring is preferably arranged in a non-detachable, materially bonded and coaxial manner on the smoke extraction opening of the base body.
  • the integral connection can be made, for example, by welding or brazing.
  • connection ring can also be detachably fastened to the base body with the aid of a thread or the like.
  • the feet are attached to the underside of the base body in order to be able to set up the fire pit.
  • the first flue pipe is attached to the connection ring so that it extends essentially completely above the base body.
  • the second flue pipe is then pushed onto the upper end of the first flue pipe in order to form the flue together with this, which then extends about twice the length of the base body beyond this.
  • the fuel preferably dried logs, are filled into the base body and ignited before the smoke exhaust pipes are fitted or through them.
  • the smoke exhaust pipes are removed, one inside the other plugged in and sunk like a telescope in the base body.
  • the ash that has accumulated in the base body is poured out of it beforehand.
  • the feet are dismantled and preferably pushed into the second internal smoke outlet pipe.
  • the outer dimensions of the fireplace are essentially reduced to the size of the base body. This can also be stowed in a transport bag to avoid contamination during transport.
  • An advantageous embodiment of the fireplace is further characterized in that a pattern is cut out of the material in at least one of the two smoke exhaust pipes. This is primarily to improve the appearance of the tube, particularly when this pattern is illuminated from the inside of the tube as the fuel burns.
  • the pattern can be lettering that also serves as a branding feature for the fireplace.
  • such patterns or lettering can also be applied to the surface of the base body or embossed into it.
  • the barrel-shaped base body 02 is a modified KEG-50 DIN type stainless steel beer keg with a capacity of 50 liters.
  • the stainless steel beer keg 02 has a smoke extraction opening 03 on its first end face, which forms its upper end face in the operating state.
  • Twelve air inlet openings 04 are arranged on the circumference of the base body 02, six each along circumferential lines running parallel to one another.
  • the air inlet openings 04 are offset from one another by 60°, for example, and have an opening diameter of approximately 42 mm.
  • the air inlet openings 04 are drilled into the material of the base body and are used to supply combustion air.
  • the base body 02 has several circumferential stabilization rings 05, which prevent deformation of the base body even at high temperatures.
  • foot receptacles 06 are arranged, in which three feet 11 are attached.
  • the feet are preferably at an angle of 15°-45° to the longitudinal axis of the base body and ensure a secure footing even on surfaces that are not exactly level.
  • the feet also ensure that the bottom of the base body, i.e. the second front side, which is hot during operation, does not have direct contact with the floor space, so that it is protected from excessive heat.
  • connection ring 07 is arranged, for example welded, on the central smoke extraction opening 03 .
  • the connection ring 07 allows the attachment of a first end of a first smoke exhaust pipe 08 in the operating state clear diameter of the connection ring and the smoke extraction opening 03 is selected so that the first smoke extraction pipe 08 can be sunk into the base body in a transport state.
  • a second smoke exhaust pipe 09 is arranged with its first end at the second end of the first smoke exhaust pipe 08, for example by means of a plug connection.
  • the first smoke exhaust pipe 08 has an inside diameter that is slightly larger than the outside diameter of the second smoke exhaust pipe 09, so that the second smoke exhaust pipe 09 can be inserted into the first smoke exhaust pipe 08 when the transport state is to be established.
  • the stainless steel beer keg 02, the first smoke exhaust pipe 08 and the second smoke exhaust pipe 09 have approximately the same length in the axial direction.
  • FIG 2 shows the embodiment according to FIG 1 in transport condition.
  • the first smoke outlet pipe 08 is largely sunk into the stainless steel beer keg 02 and the second smoke outlet pipe 09 is largely sunk into the first smoke outlet pipe 08 .
  • the three dismantled feet 11 are arranged inside the second smoke exhaust pipe 09, so that all the components can be transported in a compact arrangement inside one another.
