Definitions

  • the present invention relates to heat recovery devices, the construction of which is based on the principle of reducing heat losses due to radiation and convection.
  • recuperators designed to be inserted in open hearths of traditional fireplaces likely to use one or more fuels in the solid state and, more generally, wood.
  • a heat recovery device constructed for the above purposes, generally and usually comprises a first box, the upper hearth wall of which comprises a grid giving access to an ashtray disposed in the box.
  • the grid consists of exchange tubes supporting the embers and crossed by an air circulation taking calories. Hot air is released into the room.
  • the air circulation can be natural or forced by the intermediary of a motor-ventilator group included in the box, generally laterally to the ashtray.
  • An appliance of the above type also comprises a combustion box surmounting the exchange box.
  • a combustion box is delimited by the upper wall of the exchange box forming a hearth, by a bottom wall, by two side walls and by a top.
  • This structure gives the device a shape of a rectangular enclosure that can be inserted inside an open hearth of a chimney.
  • a smoke outlet orifice at the top.
  • This orifice is bordered by a nozzle on which can be fitted a casing rising through the drain, the hood and, at least in part, the flue pipe to ensure the evacuation of the latter.
  • soot which clings along the vertical walls of the flue pipe of the chimney. Due to variations in pressure and temperature, soot is permanently detached from this duct and is therefore, by gravity, caused to fall into the hood and downstream.
  • the invention aims to solve the above problems by proposing a new heat recovery device able to be inserted into the open hearth of a chimney, while offering the user easy and rapid access to the upper part of the 'insert in place, to the connection nozzle with the smoke evacuation pipe, as well as to the buffer or to the plate.
  • the invention also aims to offer the same accessibility possibilities for an insert of simple structure or, indifferently, an insert of the type with peripheral ventilation comprising, for this purpose, a jacket enveloping it on at least four faces, the above.
  • the heat recovery device is characterized in that the top wall consists of: - a rear half-plate extending perpendicular to the bottom wall, fixed on the latter and on the side walls, comprising a semi-circular median extension extending beyond the longitudinal edge directed towards the front frame and having, in its middle part and in the extension, a hole bordered by a connection nozzle rising from the upper face of the rear half-plate, a front half-plate having, in its middle part and from the longitudinal edge oriented in the direction of the bottom wall, a nesting notch complementary to the extension, said half-plate comprising removable fixing means on at least the side walls.
  • Fig. 1 illustrates the problem that the invention aims to solve, in the case of a chimney 1 whose open hearth 2 is equipped with a heat recovery device 3 .
  • a heat recovery device 3 In known manner, such an apparatus 3 is inserted into the hearth 2 to rest on the hearth 4 while being located at a distance from the counter-core 5 and the straight feet 6 .
  • the recovery device 3 is used in combination with a casing 7 intended to conduct the flue gases and combustion gases through a drain 8 , a hood 9 and a flue pipe 10 from the chimney 1 .
  • the device 3 comprises a top 11 delimiting an orifice 12 bordered by a nozzle 13 on which fits the lower end portion of the casing 7.
  • a device 3 has a front door 14 d access to the internal combustion volume which is separated from an underlying exchange volume 15 by a bottom 16 forming a hearth.
  • the invention proposes make a heat recovery device 3 , as shown in figs. 2 and 3 .
  • Fig. 2 shows, more particularly in exploded view, that the heat recovery device 3 comprises, as said previously, an exchange box 15 whose wall 16 constitutes the combustion hearth of a superimposed combustion box 18 .
  • the hearth 16 is associated with a grid 20 composed of exchange tubes 21 able to promote a circulation of heated air recycled in the room.
  • the object of the invention does not relate to the exchange means which are neither shown nor more precisely described in the following.
  • the combustion box 18 is delimited by two side walls 23 , by a bottom wall 24 , by a front frame, not shown, capable of supporting the door 14 and from above 11 .
  • the top 11 is constituted by a half-plate 25 , called rear, fixed by suitable adaptation members 26 , both on the corresponding parts of the upper edges of the side walls 23 and on the upper edge of the bottom wall 24 .
  • the edges of the walls 23 and 24 can be provided with a molding 27 intended to cooperate with a sealing bead housed in a complementary groove or groove presented by the underside of the half-plate 25 .
  • the mounting of the half-plate 25 is carried out so that the longitudinal edge 25 a of the latter is preferably located in the extension of the corresponding face of the bottom plate 24 .
  • the second longitudinal edge 25b of the half-plate 25 has, in its central region and projecting an extension 28 of the type substantially semicircular.
  • the half-plate 25 has a circular orifice 29 which is also formed in the extension 28 and in the half-plate 25 .
  • the orifice 29 is bordered by a nozzle 30 , removable or not, rising from the upper face of the half-plate 25 to a height conventional in the technical field considered, to ensure nesting and functional connection suitable with the corresponding end part casing 7 .
  • the half-plate 25 therefore has a width substantially equal to the corresponding half-measure of the top 11 , in particular when it is desired to arrange the nozzle 30 along a vertical median plane parallel to the front of the recovery device.
  • Figs. 2 and 3 show that, according to a feature of the invention, the longitudinal edge 25b of the half-plate 25 and the edge of the extension 28 have a continuous rabbet 31 formed from the upper face of the half-plate 25 to a depth corresponding to the mid-thickness.
  • the rebate 31 thus defines a range 32 offset below relative to the upper face of the half-plate 25 .
  • Such a range 32 preferably has a groove 33 for the establishment of a sealing bead of any suitable material capable of withstanding the temperature constraints prevailing locally during the operation of the recovery device.
  • the top 11 also comprises a second half-plate 35 , called the front, whose surface is complementary to the rear half-plate 25 so that, in association, they together form the top 11 .
  • the underside of the half-plate 35 includes, set back from the two transverse edges, sealing beads intended to cooperate with the moldings 27 .
  • the front half-plate 35 can be fixed to the edges of the two side walls 23 by fastening members 36 , of the type used for the half-plate 25 and passing through a dropped edge 37 extending the longitudinal front edge 35 a .
  • a flange 37 is also provided to assume a function of bracing lintel between the side walls 23 to secure the latter and facilitate, if necessary, the mounting of the front frame not shown in the drawings.
  • the front half-plate 35 delimits, in its longitudinal edge 35 b facing the half-plate 25 , a notch 38 formed in the middle part, according to a conformation complementary to that of the extension 28 .
  • the longitudinal edge 35 b delimit a rebate 41 complementary to the rebate 31 , so as to allow mutual interlocking during the positioning of the half-plate 35 .
  • the rebate 41 is therefore produced in a reverse manner to the rebate 31 , so that the flat area 42 is able to cooperate with the flat area 32 .
  • the constitution of the heat recovery device makes it possible to carry out a conventional insertion into the open hearth 2 , as illustrated in FIG. 4 , after engagement of the casing 7 through the drain 8 , the hood 9 and the duct 10 .
  • the absence of the front half-plate 35 combined with an opening or a dismantling of the door 14 , provides wide access to the drain 8 and offers a visual perception of appreciation not hindered.
  • the installer can thus carry out in the best conditions the operations of fitting the casing 7 onto the nozzle and of adjusting the draw valve 17 .
  • the front half-plate 35 can be put in place by sliding from the positions illustrated in FIGS. 2 and 4 , until the complementary interlocking of the rebates 31 and 41 is ensured.
  • This interlocking is obtained with certainty when the upper edges of the side walls 23 form the moldings 27 which then assume a function of guide rail and sliding.
  • the final fixing then takes place by the installation of the fixing members 36 passing through the lintel 37 to cooperate with counterparts 40 carried by the front edges of the side walls 23 .
  • the final constitution of the heat recovery device can then be completed by fitting the front frame and the door 14 .
  • the means implemented by the object of the invention therefore allow easy and safe mounting of the elements constituting the device, as well as a possibility of rapid disassembly of the front half-plate 35 when it is necessary to access the volume of the drain 8 for, in particular: - carry out cleaning, - adjust, dismantle or maintain the draft shutter 17 , - change the casing 7 .
  • a recovery device 3 can be provided with an outer lining jacket 50 extending away from the top 11 , the bottom plate 24 and the side walls 23 .
  • the function of such a jacket 50 is to regulate the operating temperature and to allow secondary circulation taking up the calories absorbed by the walls of the device.
  • the invention recommends making the jacket 50 in such a way that it comprises, as a top 51 , only a half panel 52 integral with the sides 53 and covering the half-plate 25 .
  • the top 51 is completed by a half-panel 54 corresponding to the half-plate 35 and, preferably, carried by the latter.
  • the half-plate 35 and the half-panel 54 make it possible to obtain, simultaneously, the reconstruction of the tops 11 and 51 or to clear the access to the drain 8 .
