Definitions

  • the present invention relates to the field of domestic heating appliances.
  • domestic heating appliances comprise a wood combustion chamber connected to a discharge pipe and possibly including baffles and include air circulation channels to be heated placed in the environment of the combustion chamber.
  • the patent US 420,503 discloses a heater in which the gases all exit a main combustion chamber through a lower grill and circulate only in a rear chamber, separated from the main chamber, towards an upper discharge duct.
  • the European patent EP 0 409 790 describes a closed hearth heater in which outside air is admitted by a fan to produce a forced circulation.
  • the outside air admitted is directed on the one hand to a main chamber located above a grid and on the other hand to a lower chamber located below the grid.
  • the gases in the main chamber and the lower chamber are directly directed from the exhaust duct.
  • the object of the present invention is to provide a heating apparatus with increased efficiency.
  • a heater which comprises, formed in a box: a main chamber having a front opening of outside air inlet and located above a grid; an upper chamber located above said upper plate and connected to an upper gas evacuation pipe, the main chamber and the upper chamber being separated by an upper plate which is provided with a communication passage between the main chamber and bedroom superior; a lower chamber located below the grid, the main chamber and the lower chamber being separated by the grid which is at least partly inclined downwards from the rear to the front; at least one auxiliary channel, a lower part of which communicates with a lower part of the main chamber by a lower passage and whose upper part communicates with an upper part of the main chamber by an upper passage; and at least one secondary channel having a lower portion communicating with said lower chamber and having an upper portion communicating with said upper chamber.
  • the main chamber and the secondary channel can be separated by a separation side wall.
  • the heater may include at least one external air supply duct in said auxiliary duct.
  • the auxiliary channel can be located at the back of the main bedroom.
  • the main chamber and the auxiliary channel can be separated by a partition wall.
  • the partition wall between the main chamber and the auxiliary channel may be provided with perforations.
  • Said lower chamber may comprise a lower wall inclined downwards from the rear towards the front, this lower wall being able to be inclined in the direction of an ashtray.
  • the heater may comprise a casing surrounding said casing and leaving a space between the casing and the casing, this casing having at least one lower outside air inlet opening in said space and at least one upper casing opening. air outlet.
  • the furnace 1 shown, open hearth, is in the form of a box 2 arranged and comprises a main chamber 3 which is located above a grid 4 and below a top plate substantially horizontal 5 separation and which is delimited peripherally by a front wall 6, a rear wall 7 and side walls 8 and 9. These walls 6, 7, 8 and 9 converge upwards. The side walls 8 and 9 converge towards the rear.
  • the front wall 6 has a front access opening 10 for loading the main chamber 3 into combustible products, such as wood, above the grid 4.
  • the separating plate 5 has a central passage 11 for the flow of gases.
  • the heating apparatus 1 comprises an upper chamber 12 situated above the upper separation plate 5 and connected to a vertical upper conduit 13 for evacuating gases towards the lower end of a chimney 14, so that the main chamber 3 and the upper chamber 12 are separated by this partition plate 5 and communicate through the central passage 11.
  • a flow control flap 13a operable from the outside.
  • the heating apparatus 1 comprises a lower chamber 15 located below the grid 4, the main chamber 3 and the lower chamber 15 being separated by the grid 4.
  • the grid 4 is inclined from the back to the front and downwards and has lateral zones 4a and 4b inclined towards an inclined median zone 4c and towards substantially horizontal front zones 4d and 4e. Thus, the grid faces the front opening 10.
  • the lower chamber 15 is delimited by a lower wall 16 facing the grid 4.
  • This lower wall 16 is inclined downwards from the rear towards the front and comprises a front part 16a going up to the front wall 6, below the front access opening 10, and in the form of a receptacle for a removable ashtray 17 which extends below the front zones 4d and 4e of the grid 4 .
  • the heating apparatus 1 comprises secondary channels 18 and 19 in the form of chambers, which are located laterally on either side of the main chamber 3 and separated from the latter by the side walls 8 and 9, so that the secondary channels are independent of the main chamber 3.
  • the secondary channels 18 and 19 are delimited by side walls 20 and 21 which are vis-à-vis the side walls 8 and 9 and which join the front wall 6 and the rear wall 7.
  • the side walls 8 and 9 which separate the main chamber 3 and the secondary channels 18 and 19 are at least partly formed by walls 8a and 9a of a refractory material capable of storing heat.
  • the lower portions of the secondary channels 18 and 19 communicate with the lower chamber 15, laterally on either side of the latter, by lateral passages located below the side walls 8 and 9.
  • the heating apparatus 1 comprises an auxiliary channel 24 arranged at the rear of the main chamber 3 adjacent to the rear wall 7.
  • the auxiliary channel 24 is delimited by a transverse partition wall 25, substantially vertical, located opposite the rear wall 7 and extending transversely between the side walls 8 and 9 of the main chamber 3.
  • This transverse partition of separation 25 is shifted rearwardly with respect to the central passage 11 and is provided with perforations 25a.
  • the lower part of the auxiliary channel 24 communicates with the lower part of the main chamber 3 by a lower passage 26 extending between the lower edge of the transverse partition 25 and the high part of the grid 4.
  • the upper part of the auxiliary channel 24 communicates with the upper part of the main chamber 3 by an upper passage 27 extending between the upper edge of the transverse partition 25 and the separating plate 5.
  • the heating apparatus 1 comprises ducts 28 for supplying outside air into the auxiliary duct 24. These ducts 28, which are substantially vertical, pass through the grate 4, the lower chamber 15 and the plate 16 and open upward substantially at half of the height of the auxiliary channel 24 and downwards in an auxiliary lower chamber 29 located below the lower chamber 15.
  • This auxiliary lower chamber 29 is connected to the outside by a rear passage 30 in which is provided a flow control flap 30a operable from the outside.
  • conduits 28 distributed transversely may be provided.
  • horizontal deflectors 31 and 32 for slowing flow, providing baffles between the central passage 11 of the separating plate 5 and the lower inlet of the upper discharge duct 13.
  • the general flow can be adjusted through the upper flap 13a.
  • the flow in the feed ducts 28 can be adjusted by means of the lower flap 30a.
  • the heater 1 has the following advantages.
  • the walls 8a and 9a of the side walls 8 and 9 contribute to the heating device 1 having a thermal inertia.
  • the heating apparatus 1 further comprises an outer casing 33 which remotely surrounds the casing 2 leaving a space 34 between the casing 2 and the casing 33.
  • This casing 33 has a front opening 34 corresponding to the front opening 10 of the box 2.
  • the casing 33 has at least one lower external air inlet opening in the space 34 and an upper air outlet opening, so that the air circulated in the space 34 is reheated.
