Abstract

A closed fireplace (1) having a display glass, a hearth provided with a grating (29), an ignition device, an ash receptacle (31), a combustion replacement air supply and a discharge line for fumes. The fireplace also having a flat body chamber (2) in the form of a closed box to be attached to a wall or partially or fully integrated into the wall or into a canopy thereof, the internal volume of the flat body being divided into two flat adjacent chambers for combustion (4) and storage (5), the storage chamber forming a stock of wood (6). The chambers are separated by a dividing and thermally insulating wall (8) for supplying the pre-heated secondary air for the combustion, the bottom of the storage compartment having an inclined ramp ending in the lower part of a hearth (34). The invention is especially suitable for manufactures of fireplaces especially designed for wood fires.

Claims

1-32. -32. (canceled)

33. A closed-hearth fireplace (1) for solid fuel comprising a display glass (3), a hearth equipped with an ash grate (29), an ignition device, an ash receptacle (31), an inlet for new combustion air and a smoke outlet, the fireplace further having a flat body in a case (2) formed of a closed box to be one of placed against a wall, partially and totally embedded within the wall, and an interior space of said flat body inside the box (2) is separated into two adjacent flat chambers, a combustion chamber (4) and a storage chamber (5), the storage chamber (5) forming a reserve (6) of the solid fuel separated by a separating wall (8), a portion of the front surface of the flat body in the case (2) facing the combustion chamber (4) is closed during operation by the display glass (3), the display glass (3) is opened for access to the combustion chamber (4) and for cleaning, and the storage chamber (5) forming the reserve (6) of the solid fuel constitutes, in a lower portion, a device for automatically supplying the solid fuel stacked inside the storage compartment to the combustion chamber (4) and a front surface of the case (2), previously closed on a portion facing the combustion chamber (4) by the display glass (3), is closed by a principal door (56) made of one of glass and similar material with a transparent central surface (58) opposite the display glass (3) and a dual supply of combustion air coming from a principal inlet and a secondary air inlet.

34. The fireplace according to claim 33, wherein the principal door (56) is double paned.

35. The fireplace according to claim 33, wherein when closed, the principal door (56) and the display glass (3) represent three thicknesses of glass for viewing a flame as a direct image and as a reflective image of the flame.

36. The fireplace according to claim 33, wherein the separating wall (8) is hollow.

37. The fireplace according to claim 33, wherein the separating wall (8) is thermally insulated.

38. The fireplace according to claim 33, wherein an interior space within the separating wall (8) is one of partially and totally filled with a thermally insulating material.

39. The fireplace according to claim 33, wherein the combustion air, passing through an interior space in the separating wall (8), becomes heated and thermally insulates the combustion chamber (4) from the storage chamber (5).

40. The fireplace according to claim 33, wherein the separating wall (8) opens at least at a lower portion (13) to draw new secondary combustion air into the hearth.

41. The fireplace according to claim 33, wherein the separating wall (8) also has a secondary combustion air outlet in the upper portion of the hearth for post combustion.

42. The fireplace according to claim 33, wherein a secondary combustion air outlet is a linear ramp (17) formed of orifices communicating with a space inside the separating wall (8) for the purpose of post-combustion.

43. The fireplace according to claim 33, wherein secondary combustion air is forced by a mechanical means into a space inside the common wall (8).

44. The fireplace according to claim 33, wherein primary combustion air arrives through a front air inlet register (27).

45. The fireplace according to claim 33, wherein a front air inlet register (27) comprises a piece that moves in translation (20).

46. The fireplace according to claim 45, wherein the piece that moves in translation (20) is mechanically controlled by the heath grate (29).

47. The fireplace according to claim 33, wherein the storage compartment (5) forming the solid fuel reserve (6) is one of a storage compartment or chamber (5) situated in a rear of the hearth, open at a bottom and adjacent to the hearth, separated from the hearth by the separating wall (8), a depth of the storage chamber (5) correspondents to an average diameter of a log, said compartment being filled either one of directly and by reloading with one of horizontally stacked logs or rounds (7).

48. The fireplace according to claim 33, wherein the storage chamber (5) forming the reserve (6) of fuel opens at a bottom onto an inclined ramp (34) along which the fuel slides for automatically supplying fuel, by gravitational force, to the hearth by causing the fuel to pass laterally through the lower opening in the storage chamber (5) by gravity until the fuel reaches a level of a hearth grate (29) so that when a first portion of fuel has been completely consumed, another portion of fuel takes its place.

49. The fireplace according to claim 33, wherein a lower outlet opening in the storage chamber (5) is a portion extending between an inclined ramp (34) and a lower edge of the separating wall (8).

50. The fireplace according to claim 33, wherein a lower outlet opening is equipped with a means for admitting the fuel into the hearth.

51. The fireplace according to claim 50, wherein the means for admitting is a valve type means.

52. The fireplace according to claim 33, wherein the fuel reserve (6) comprises a reloader (62) introduced inside the storage chamber (5) by a loader.

53. The fireplace according to claim 52, wherein the loader receives the reloader (62).

54. The fireplace according to claim 33, wherein the fireplace comprises an ignition device.

55. The fireplace according to claim 54, wherein the ignition device comprises a plated electrical resistor (38).

56. The fireplace according to claim 54, wherein the ignition device is remotely controlled.

57. The fireplace according to claim 33, wherein the case (2) is laterally closed by two pivoting doors (39, 40), with an area (43) opposite an access opening to the storage chamber being lined and thermally insulated.

59. The fireplace according to claim 58, wherein an outlet of smoke box (46) is horizontal, forming an outlet through one of an adjacent wall and vertical.

60. The fireplace according to claim 33, wherein smoke evacuation is accomplished through a conduit (52) that is also used for admitting the combustion air, through two concentric conduits traversing an adjacent wall, one for evacuating smoke and one for admitting the combustion air.

61. The fireplace according to claim 33, wherein intercalary layers of combustible material are interposed between portions of the fuel.

62. The fireplace according to the claim 33, wherein a principal combustion air inlet (18) is thermostatically controlled.

63. The fireplace according to claim 33, wherein a secondary combustion air inlet (14) is thermostatically controlled.

64. The fireplace according to claim 33, wherein two inlets for combustion air (18, 14) are thermostatically controlled.
