Definitions

  • the present invention relates to a device for a chimney of the open fire type, the hearth plate and the reluctant of which are offset from the ground and from the rear frame in order to constitute a sheath in communication by means of an air intake with the outside. and by means of exhaust vents with the room containing the chimney.
  • fireplaces of the open fire type comprising a horizontal hearth plate and a vertical plate constituting the reluctant offset from the ground and the rear frame in order to constitute a sheath in communication by means of an air intake with the outside so that the outside air drawn in by the heat heats up during its passage in the duct in contact with the plates and rectilinear metal fins attached to said plates before being diffused into the room containing the chimney through mouths or pipes connecting the duct to said part, in order to direct the air so that it licks the underside of the hearth plate and fins, a horizontal sheet constituting a baffle is disposed intermediate between the hearth plate and the ground, it rests on the rear frame and is interrupted before the frame before plate support in order to allow the passage of said air.
  • the object of the invention is to perfect the heat exchange between the plates and attached fins and the outside air drawn in, to allow, by design, to be mounted in any existing chimney or to be constructed chimney.
  • the device which is the subject of the invention comprises a folded sheet metal element constituting the horizontal hearth plate and the vertical reluctance, under the hearth and reluctant plate are added perforated continuous fins of sinusoidal shape, these are welded continuously on the element, they are arranged vertically and converge towards the center of the element at the level of the fold where the heat of the hearth is most intense, the top of their waves are alternated so as to create a constriction.
  • a folded sheet element constituting a continuous sheath, said element is offset from the edge.
  • the hearth plate and reluctantly are made in. two independent elements provided with projecting teeth distributed over their entire surface so as to constitute baffles in order to create turbulence to promote the exchange of heat between the hearth plate, reluctantly and teeth during the passage of air in the sheath constituted by a single horizontal baffle plate placed between the hearth plate and the ground above the outside air intake, the extension of the sheath vertically in line with the reluctance being achieved by simply shifting the reluctance of the rear frame of the chimney or by a vertical plate extending the horizontal baffle plate, the plate or plates being placed in abutment on the end of the teeth, the horizontal baffle plate being it offset from the front of the hearth plate so as to allow the passage of air drawn from outside through the sheath at the front of the hearth plate.
  • the device adaptable to an existing or to be built chimney comprises an element 1 of folded sheet metal constituting the hearth plate 2 and reluctantly 3, provided with fallen edges on its periphery 4, 4a, 4b, 4c, on the fallen edges 4, 4a, 4b, 4c, is fixed a folded sheet 5 constituting a sheath 5a, said sheet is interrupted before the fallen edge 4a in order to constitute an opening 6, on the edges fallen 4c in line with the edge 4b, openings 7 are arranged.
  • fins 8 and 9 of sinusoidal perforated shape, they are arranged so as to converge towards the central part at the level of the fold 10 of the element 1, the fins 8 and 9 are connected between them by welding in order to achieve continuity, their wave tops 11a are placed face to face in order to create a constriction 11.
  • the fins 8 develop from the folded edge 4a or they can be fixed by welding to the vertical face of the folded sheet metal element 5 while the fins 9 are interrupted at the lower level of the openings 7 and this in order not to slow the evacuation of the heated air in the room, intermediate fins 9a are attached to the fin central 9b in order to fill the space due to the convergence of said fins, between the central fin 9b and the neighboring fins 9.
  • the fins 8 and 9 are welded to the element 1 continuously so as to ensure perfect transmission of the heat produced by the hearth to said fins 8 and 9 while the latter are spot welded to the element 5.
  • the device is arranged in existing chimneys or to build the rear face 12 of the folded sheet 5 bearing on the rear frame 13 of the chimney or on added insulation such as insulating cellular concrete 14, the face 15 of the sheet 5 is offset from the ground 16 and placed above an external air intake 17 so as to constitute a corridor 18 closed on the front face of the chimney by the frame 19 so that the air, sucked in from the outside by the vacuum generated by the heat source, passes through the sheath 5a in order to cause a heat exchange between the air, the fins 8 and 9 and parts 2 and 3 of the element 1, said exchange being favored by the throttles 11 which create turbulence and the slowing down of the air flow which forces part of this air to pass through the perforations, which creates secondary turbulences improving the exchange, the air thus heated is evacuated through openings 7 and outlets 20 extending them arranged on the legs 21 of the chimney and thus diffused in the room containing the chimney.
  • the convergent arrangement of the fins 8 and 9 towards the central part has the effect of directing part of the air towards the center of the device where the heat is the most intense, which has the further effect of causing a heat exchange between the elements metallic and air, but also to ensure during the exchange the cooling of this part where the heat is the most intense in order to avoid the deformation of said metallic elements in this place.
  • the offset support of the device floor is achieved by an attached frame 22 placed in abutment on the legs 21, the immobilization of said element is ensured by prefabricated panels 23 of refractory bricks or of all other refractory materials, said prefabricated panels 23 are immobilized by means of lag screws 24 and dowels 25 on the legs 21.
  • an insulating joint 26 is added between the folded sheet 1 and the prefabricated panel 23, it is the same at the folded edge 4b where an insulating joint 27 is added between said edge 4b and a reinforced plaster groove 28 allowing inter alia the free extraction of the device after removal of the prefabricated panels 23.
  • the hearth plate 31 and reluctantly 32 are provided with projecting teeth 33 integral with said plates 31 and 32, the teeth 33 are distributed over the plates so as to create baffles in order to generate turbulence during the passage of air in the sheath 34 between said teeth 33 to promote heat exchange between the plates 31 and 32, teeth 33 and said air drawn from outside through the mouth 35 shown in Figure 3 directed by means of the attached plate 36 at the front of the hearth plate 31 and sheath 34, said air after passing through the sheath 34 is evacuated through mouths 37 arranged in line with the end 38 of the reluctant 32 on the legs 39 of the chimney, as shown in FIG. 10.
  • the teeth 33 of the plates 31 and 32 are distributed so as to create sinusoidal corridors 40 and this in order to facilitate the flow of air without thereby preventing the turbulence necessary for good heat exchange, according to the embodiment shown in FIG. 11, the teeth 33 are arranged in a so-called staggered distribution, so that each gap 41 between the teeth 33 is masked by an offset tooth 33.
  • the teeth 33 of frustoconical shape or any other have a section near the plates greater than the extreme free section 42 and so as to facilitate demolding.
  • the sheath can be produced in a single horizontal baffle plate shown in FIG. 9 or a horizontal plate extending vertically as shown in FIG. 4.
