Definitions

  • the invention relates to an air supply device according to the preamble of patent claim 1, a method for producing an air supply device according to the preamble of patent claim 4, a fresh air intake box for carrying out the method according to the preamble of patent claim 7 and a distribution box for carrying out the method according to the preamble of patent claim 10 .
  • a partially open firebox of a fireplace (fireplace) as well as a firebox (oven) that is closed to the air supply is used in residential complexes and is intended to contribute to a cozy living atmosphere, especially on cold and damp days.
  • a firebox an open firebox in a residential complex.
  • the air supply is u. a through window and door cracks. Since the air supply is often not sufficient, smoke can enter the living room.
  • the air required is through a partially open basement window and a floor opening in fed in the immediate vicinity of the combustion chamber. This cools down the basement; the window must be barred so that no animals (mice, rats, martens, cats) enter the basement.
  • the fireplace of the combustion chamber is in the immediate vicinity of an outer wall of the building, in which there is an opening. Air is sucked in through this opening due to the hot flue gases leaving the room through the chimney. The sucked-in air is often passed through a heat exchanger for heating, which is heated by the hot flue gases or by the radiant heat of the fire.
  • This known air supply device works satisfactorily in terms of the amount of air supplied and its heating; however, the location of the open firebox is tied to the vicinity of an outer wall of the building.
  • the invention has for its object to provide a simple to install air supply device of the type mentioned, which makes it possible to arrange the combustion chamber on any floor of a building spaced from the building exterior walls and to ensure sufficient air supply for the combustion process in the combustion chamber.
  • the solution to the problem with regard to the air supply device is the subject of claim 1, with regard to the method for the air supply device the subject of claim 4, with regard to the fresh air intake box for carrying out the method, the subject of claim 7 and with regard to the distribution box for carrying out the method, the subject of claim 10.
  • the air supply device shown in FIG. 1 for supplying air to a partially open fireplace 1 with a combustion chamber 2 , shown schematically in FIG . 2, has a fresh air intake box 3 , which is connected to a distribution box 7 by four flexible pipes 5a to 5d .
  • the distribution box 7 and the flexible pipes 5a to 5d lie within a casing (not shown) above the reinforcing iron 9 of a building ceiling 11 to be created.
  • the distribution box 7 is fastened to four brackets 13 via a spacer 15 with nails 17 against displacement on the formwork.
  • the fresh air intake box 3 is approximately in the same horizontal position with respect to the distribution box 7 in the outer wall 19 of the building and is also fastened by means of four spacers 15 with nails 21 .
  • It consists of a basic box 23 in which a tube 25 is slidably inserted.
  • the basic box 23 is a cuboid, open on one side, provided with an edge 24 , both of which face away from the open side Corners 27a and 27b are chamfered at approximately 45 ° and each carry a pipe connection piece 29a and 29b .
  • a further two pipe connecting pieces 29c and 29d are located on the side facing away from the open side.
  • the base plate of the base box 23 is approximately square and forms below the chamfered corners 27a and 27b two perforated tabs 31a and 31b , which serve for the above-mentioned attachment of the base box 23 during the manufacture of the building ceiling 11 and the building outer wall 19 .
  • the sides 33a and 33b are slightly conical to the rear side, in order, as explained below, to be able to easily pull out an inserted proppant.
  • the tube 25 is designed as a square tube such that it can be moved within the basic box 23 .
  • the tube 25 projects beyond the base body 23 by a distance d .
  • the distance d corresponds to the sum of a minimum thickness of a building insulation 35 to be applied to the outer wall 19 of the building and a plaster 36 to be applied thereon. If a thicker building insulation 35 or a thicker plaster 36 is attached, the tube 25 can be pulled out of the basic box 23 accordingly.
  • the opening 38 facing away from the basic box 23 serves as an air inlet opening and is surrounded by an edge 40 .
  • the tube 25 can be pushed into the edge 24 of the basic box 23 until its edge 40 stops.
  • the distribution box 7 is a cuboid box with corners 37a to 37d which are chamfered at approximately 45 ° and two air outlet openings 39a and 39b on its upper side.
  • the base plate of the distribution box 7 is approximately square and forms below the beveled corners 37a to 37d the four holes 13 provided with holes, which serve for the above-mentioned attachment of the distribution box 7 during the manufacture of the building ceiling 11 .
  • the air outlet openings 39a and 39b are connected to a heat exchanger 45 shown in FIG. 2 via two pipes 43a and 43b .
  • the heat exchanger 45 is around a chimney 47 through which the flue gases of a combustion chamber 2 open on three sides and above the Firebox 2 , arranged.
  • the fourth side of the firebox 2 forms a building inner wall 50 clad with fireclay tiles (not shown), on which the chimney 47 is led up to the roof (not shown).
  • the heat exchanger 45 has an outlet opening 51a to 51c ( 51a not shown) on each of the three open room sides, through which heated air can flow out in the heat exchanger 45 .
  • the installation of the air supply device for the fireplace 1 takes place when the building is being built during the production of the building ceiling 11 .
  • a casing (not shown) is built, which supports the concrete of the building ceiling 11 up to its own load-bearing capacity.
  • a grid of reinforcing iron 9 is laid in the formwork, and then the distribution box 7 with air outlet openings 39a and 39b located at the location of the fireplace 1 to be created, as already mentioned above, on its four tabs 13 on spacers 15 on the formwork with the nails 17 secured against moving.
  • the tube 25 of the fresh air induction box 3 is completely inserted into the base box 23 and foamed inner cavity 3 of the fresh (not Pictured) or a foam (not shown) foam block (-quader) introduced as a proppant.
  • the foam is intended to prevent the fresh air intake box 3 from being compressed when the outer wall 19 of the building is later pulled up.
  • the air inlet opening 38 of the fresh air intake box 3 and the air outlet openings 39a and 39b of the distribution box 7 are closed (for example with plastic lids), so that no concrete or dirt can penetrate during the production of the building ceiling 11 and the building outer wall 19 .
  • the fireplace 1 can be created with the interior of the room in question and the heat exchanger 45 , as already explained above, can be connected to the air outlet openings 39a and 39b of the distribution box 7 .
  • the foam is removed from the fresh air intake box 3 through the air inlet opening 38 . It can be pulled out without any problems since, as explained above, the width of the fresh air intake box 3 increases slightly towards the air inlet opening 38 . Then a building insulation 52 and a plaster 53 is applied to the outside of the building outer wall 19 .
  • the tube 25 is pulled out of the basic box 23 of the fresh air intake box 3 until its edge 40 rests on the outside of the plaster 53 .
  • the edge 40 has two holes 54 , which are used to fasten the tube 25 with screws or nails in the plaster 53 or in the building insulation 52 .
  • the tube 25 is only fastened with two screws and is otherwise freely displaceable in the basic box 23 , it can be removed quickly and easily for maintenance or to replace the cross-flow fan 55 .
  • a closed firebox can also be used.
  • the distribution box 7 can be analogous to the fresh air box 3 with a (not shown) foam block, which later again through one of the air outlet openings 39a . 39b is removed, are supported during concreting.
  • the air supply device consists of a prefabricated distribution box 7 and a prefabricated fresh air intake box 3 , which only has flexible pipes 5a to 5d , which can be easily cut to the desired length on the construction site using sheet metal shears or a saw, an extremely simple and quick, modular assembly guaranteed. Due to the extendable tube 25 , the fresh air intake box 3 can always be installed flush with the outside of the building; Additional insulation or weather protection panels can be easily attached during later building inspection work. Since a plurality of pipes, preferably four pipes 5a to 5d , are used as the connection between the fresh air intake box 3 and the distribution box 7 , a large amount of air can be transported with a low flow resistance without any significant weakening of the building ceiling 11 . Due to the large flow cross-section, the air speed is low, which means that no disturbing noises occur.
