Definitions

  • the invention relates to a double-stage fireplace which will find its application in particular in the field of domestic heating.
  • the closed hearth chimney is used.
  • the hearth is closed by front doors, and the hearth is supplied with oxygen by air supply pipes where the flow is regulated.
  • the burnt gases are obviously evacuated by a smoke evacuation duct and exchangers are very often set up to recover the calories and distribute them to different chosen places.
  • the closed door heating speed corresponds to a high energy efficiency and maximum efficiency of the chimney, however, the spectacle of the flames cannot be observed due to the presence of the closed doors.
  • the other stage of heating which corresponds to the operation of the open hearth fire, on the contrary, makes it possible to benefit from the spectacle of the fire in which case the doors are opened so as to leave the apparent hearth.
  • the fireplace is often not used as a generator of calories to be dispersed in different rooms of the house but as a decorative element to create a spectacle and release of heat in its immediate environment.
  • the main purpose of the present invention is to present a double-stage chimney that is fully transformable to adapt, both aesthetically and operation to the heating regime adopted.
  • the double-stage chimney of the present invention is similar to traditional closed hearth fireplaces, that is to say the presence of massive doors closing off the hearth when the chimney operates with closed hearth and also to chimneys open without door during open hearth operation.
  • the doors of the fireplace of the present invention are retractable without disassembly therefore with great ease of operation and allow to offer the spectacle of an open hearth operation without the visible presence of the doors. On the aesthetic and practical level, this is an improvement over the existing system.
  • the double-stage chimney of the present invention also makes it possible to adapt as best as possible in terms of thermal efficiency to the chosen heating regime.
  • a manufacturer must make a choice either he favors the closed door operation to obtain a good output or he favors the fire show by opening the doors or by using a glazed door with a very large air intake to the detriment of the output.
  • the chimney exhibits optimal characteristics in the two heating regimes.
  • the double-stage chimney particularly finding its application in the field of domestic heating, which comprises a hearth closed by one or more front doors is characterized by the fact that the lateral convection boxes are articulated and allow the retraction of the or the front doors in their interior volume so that the doors can be folded against the side walls of the hearth.
  • the present invention relates to a double-stage fireplace which will find its application in particular in the field of domestic heating.
  • Figure 1 shows schematically a double-stage chimney 1 which in the case of the figure is shown as operating with a closed hearth.
  • the hearth is closed by two front doors 2 and 3 and surmounted by a fume hood 18.
  • a double-stage chimney operating in closed mode is used in its high-efficiency functional mode. This is why a maximum of calories must be evacuated from the chimney in order to recover them to heat different places.
  • the hearth is generally formed of double side walls between which an air circulation is ensured by convection. This air, taking away the calories released by the hearth, can be directed to the places that need to be heated.
  • Figure 1 shows schematically the side boxes and 5 which act as a double wall for the hearth and in which an air circulation shown diagrammatically by the arrows 6 is ensured.
  • the air enters through the lower part of the box 7 and exits through orifices 8 made in the upper part of the boxes and 5.
  • the double-stage chimney 1 has lateral convection boxes 4 and 5 which are articulated and which allow the front doors 2 and 3 to be retracted into their internal volume so so that the doors can fold back against the hearth walls.
  • FIG. 2 represents the case in which the lateral boxes 4 and 5 have a vertical axis of articulation 9 arranged on the rear of the chimney. Being able to open the side boxes 4 and 5 in a way like a wallet allows the doors to be stored in their interior volume.
  • FIG. 3 represents the case of side boxes 4 and 5 having a horizontal axis of articulation 10.
  • the side boxes When the side boxes are folded down, they mask the doors, hence the pleasant aesthetics of the open hearth fireplace.
  • This objective can be achieved by judiciously arranging the fixed air discharge orifices so that the latter are completely or partially closed off by the front doors 2 and 3 when the latter are folded down and contained in the interior volume of the side boxes 4 and 5.
  • the front doors can perfectly cover the exhaust air orifices 8 of the hot air.
  • the orifice 7 for introducing fresh air can also be closed by the front doors 2 and 3 when these are folded down inside. side boxes.
  • the side boxes must be able to be installed regardless of the heating rate chosen, Also, the side boxes 4 and 5 have on their front face cutouts 11 in which are housed hinges 12 for hinge doors.
  • hinges 12 are slightly offset to the outside so that this arrangement allows the folding of said doors flat against the side walls of the hearth.
  • FIG. 4 shows a top section view of such an arrangement of the hinges 12.
  • the interior volume of the lateral boxes 4 and 5 is largely dimensioned so that the positioning of the doors in their interior volume modifies only slightly the section of the air passage by convection.
  • the doors must be able to be applied against the side walls 13 and 14 of the hearth 15 with close contact so that good thermal conduction can be ensured. In this way, the calories pass through the side walls 13 and then through the folded doors 2 and 3 before reaching the air in circulation in the interior volume of the side boxes. It is necessary to eliminate all the air between the side walls of the hearth 13 and 14 and the doors 2 and 3 to facilitate maximum heat conduction.
  • the side boxes 4 and 5 will preferably be made of an insulating material so as to reduce heat losses.
  • the lateral boxes 4 and 5 have on their front face a recess 16 which acts as a stop for the front doors when these are operated without first opening the side boxes 4 and 5.
