Definitions

  • the invention relates to a heating device comprising an air guiding device, as well as a housing with a combustion chamber door which can be opened as required in a side wall of the housing, a combustion chamber arranged inside the housing and accessible via the combustion chamber door and at least one outlet opening in the combustion chamber, via which an air supply duct, in particular for secondary air , Is connected to the combustion chamber, that a supplied air flows along an inner side of a transparent viewing window in the combustion chamber door.
  • the DE 94 01 949 U1 describes an air guiding device for a heating device with a combustion chamber for solid fuels and a door assembly which is provided with at least one transparent, in particular crystal-clear viewing window.
  • the secondary air distribution channel is connected to the combustion chamber via a plurality of outlet openings distributed over the length of the secondary air distribution channel.
  • an air distribution body extending over the entire width of the viewing window is arranged, which consists of nonflammable or high temperature resistant materials, in particular a fleece, a knitted fabric, a woven fabric or a confused mass of fibers or a spatial Shaped body consists of a plurality of side by side arranged in planar rows Kapillarbohrept and has at least a thickness of greater than 2 mm in the flow direction.
  • the at least one outlet opening for the scavenging air which scavenging air is typically subsequently also used as secondary air for maintaining the combustion process in the heating device, arranged in the region of the inside of the visor, that the purging air exiting from the at least one Auslassöffhung flows along the inside of the lens and forms the protective air curtain.
  • deposits of combustion residues or streaks on the inside of the viewing window still persist in some cases, so that the viewing window is primarily after a longer period Operating time becomes blind.
  • the present invention is therefore based on the object to improve the supply of scavenging air to the inside of the lens of the heater, so that a deposition of combustion residues on the inside of the lens, especially after a longer period of operation, is practically impossible.
  • the object of the invention is achieved with an air guiding device for a heating device of the type mentioned above, which air guiding device is formed from an air-impermeable material, in particular metal, and which air guiding device is arranged next to the at least one outlet opening in the combustion chamber and the supplied air or scavenging air a planar front side of the air guiding device flows along, which has front side projections, in particular knobs.
  • the at least one outlet opening is arranged in an upper region of the combustion chamber and if, with the combustion chamber door closed, the preferably vertically oriented front side of the air guiding device is arranged opposite the inner side of the combustion chamber door above the viewing window.
  • the supplied scavenging air basically drops by itself from the upper region of the combustion chamber into a lower region of the combustion chamber, since the scavenging air supplied is colder and thus heavier than the heated air already present in the combustion chamber.
  • the supplied scavenging air flows while doing along the inside of the lens and flushes them or protects them by forming an air curtain from the deposition of combustion residues or soot particles.
  • the provided with the projections front of the spoiler due to the arrangement of the spoiler relative to an inside of the combustion chamber door over the visor and not about an inside of the visor from the outside through the lens is not visible and the spoiler thus covers no part of the lens ,
  • a distance between the tip or end regions of the projections and the inside of the combustion chamber door is less than 1.5 cm, in particular less than 1 cm, preferably approximately 0.5 cm. In this way, on the one hand a sufficient equalization of the air flow is ensured and on the other hand, due to the remaining flow cross-section for the supplied air sufficient supply of the heater with purging air or secondary air ensured.
  • the air guiding device is fixed to the rigid part of the housing, in which part of the combustion chamber is housed, and is covered or covered by the closed combustion chamber door.
  • an increase in the weight of the combustion chamber door is avoided, which would occur if the spoiler was fixed to the combustion chamber door.
  • a difficult handling or operability of the combustion chamber door is avoided due to the increased weight.
  • the air guiding device extends at least over an entire width of the viewing window of the combustion chamber door. In this way, a comprehensive or complete flushing of the inside of the lens and thus a complete protection of the inside of the lens is ensured against deposits of combustion residues.
  • the air guiding device extends at least over an entire width of the combustion chamber.
  • the projections on the front side of the air guiding device have a height of approximately 0.5 cm. In this way, both a sufficient equalization of the supplied scavenging air flow and a sufficiently large passage cross-section for the supply of sufficient scavenging air or secondary air is ensured in the combustion chamber.
  • the projections are arranged at the front of the spoiler in at least three horizontal rows, wherein the projections are arranged offset in two superimposed rows to each other is particularly advantageous.
  • the staggered arrangement of the projections in superimposed rows means, in particular, the arrangement of an overlying or underlying protrusion just above or below the space between two protrusions in the row below or above. In this way, a particularly good homogenization or mixing of the different flows in the supplied purging air is ensured.
  • the front of the spoiler has a height of about 7 cm. In this way, on the one hand sufficient space for the arrangement of the projections is present, thus ensuring a sufficient homogenization of the supplied scavenging air or secondary air and on the other hand, by no great resistance to the flow of rinsing or secondary air is generated.
  • the air guiding device is formed with the projections of a one-piece casting.
  • a very cost-producible air deflector is created, which also has a very stable structure. This is particularly advantageous in connection with an arrangement of the air guiding device in the region of the combustion chamber door of the heating device, since possibly more or less heavy logs are introduced into the combustion chamber through the open combustion chamber door, in which process the air guiding device can be exposed to corresponding forces. Due to the stable design of the spoiler damage the same are avoided.
  • Fig. 1 shows an embodiment of a heater 1 in the form of a stove for burning wood logs in a combustion chamber 2 of the heater 1.
  • the invention in heaters 1 for a variety of fuels, such as pellets or wood chips, can be used.
  • a housing 3 of the heating device 1 comprising four side walls and an upper and a lower end wall has, in a front side wall 4, a combustion chamber door 6 with a transparent viewing pane 7 which can be opened or locked via a handle 5 as required.
  • the housing 3 of the heater 1 rests with its lower end wall on a lower support level 8, which is usually formed by a foot or ground.
  • the flue gases which form during combustion can escape from the combustion chamber 2 via an outlet opening 13 formed in an upper region 12 of the combustion chamber 2 into a chimney pipe (not shown).
  • the air supply can be controlled or regulated in the combustion chamber 2.
  • the illustrated embodiment of the heater 1 comprises three outlet openings 18, 19, 20 for the transfer of the secondary air 16 from the air supply duct 17 into the combustion chamber 2 of the heater 1.
  • the amount of supplied air or the primary air 15 and secondary air 16 fed into the heater 1 can be adjusted with an actuator 21.
  • an air guiding device 22 is arranged, which is formed of an air-impermeable material, in particular metal.
  • the spoiler 22 is formed together with the projections 25 by a one-piece casting.
  • the spoiler 22 extends at least over an entire width 26 of the combustion chamber 2, so that a uniform and sufficient supply of the combustion chamber 2 is ensured with secondary air 16.
  • the spoiler 22 is wider than the combustion chamber 2 executed.
  • the spoiler 22 is at least so wide that it extends over an entire width 27 of the window 7 of the combustion chamber door 6. This ensures that the scavenging air curtain, which is made even more uniform by the air guiding device 22, flows over the complete area in the region or on an inner side 28 of the transparent viewing window 7 in the combustion chamber door 6 and avoids contamination of the inner side 28 of the viewing window 7 by combustion residues.
  • a particularly advantageous embodiment with a closed combustion chamber door 6 the preferably vertically oriented front side 24 of the spoiler 22 with the projections 25 against an inner side 29 of the combustion chamber door 6 in an area above the lens 7 is arranged.
  • a through-channel 30 for the supplied air 23 is formed between the inner side 29 of the combustion chamber door 6 and the front side 24 of the air-guiding device 22, in which through-channel 30 the projections 25 ensure a mixing or equalization of the supplied air 23.
  • the viewing window in particular as flat as possible and / or to arrange the inner side 28 of the viewing window 7 in a direct or vertical line as far as possible under or below the through-channel 30, so that the uniformized flushing outlet emerging from the through-passage 30 or secondary air 16 flows as close as possible to the inside 28 of the lens 7.
  • a distance 31 between the tip or end regions 32 of the projections 25 and the inner side 29 of the combustion chamber door 6 with the combustion chamber door 6 closed is less than 1.5 cm, in particular less than 1 cm, preferably approximately 0.5 cm.
  • the projections 25 on the front side 24 of the air guiding device 22 have a height 33 of approximately 0.5 cm. Furthermore, the projections 25 are arranged on the front side 24 of the spoiler 22 in three horizontal rows, wherein the projections 25 are arranged offset in two superimposed rows to each other "gap".
  • the front side 24 of the spoiler 22 has a height 34 of approximately 7 cm.
