Description

La présente invention a trait aux cheminées du type à foyer fermé et à combustion apparente.The present invention relates to fireplaces of the closed hearth and apparent combustion type.

On sait que les cheminées de ce type comprennent généralement une carcasse à profil parallélipipédique dont l'une des faces latérale est agencée à la manière d'une porte vitrée éclipsable. A l'intérieur de cette carcasse débouchent un conduit inférieur d'admission d'air frais pour la combustion du bois, et un conduit supérieur d'évacuation des fumées et gaz chauds relié à une gaine de toiture.It is known that chimneys of this type generally comprise a carcass with a rectangular profile, one of the side faces of which is arranged in the manner of an eclipsable glass door. Inside this carcass open a lower fresh air intake duct for the combustion of wood, and an upper duct for evacuating smoke and hot gases connected to a roof sheath.

On conçoit dans ces condutions qu'une telle cheminée est obligatoirement adossée contre une paroi murale, la combustion n'étant apparente que sur une seule face de l'ensemble.It is understood in these condutions that such a chimney is necessarily leaned against a wall, the combustion being apparent only on one side of the assembly.

A l'inverse, la présente invention a pour but de permettre la réalisation d'une cheminée qui, tout en comportant un foyer fermé, permet la vision de la combustion sur toutes ses faces latérales.Conversely, the present invention aims to allow the realization of a chimney which, while having a closed hearth, allows the vision of combustion on all its side faces.

La cheminée suivant l'invention est définie à la revendication 1.The chimney according to the invention is defined in claim 1.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:

Fig. 1 est une vue en perspective montrant une cheminée établie suivant l'invention (avec sa coiffe vitrée à la position relevée de chargement) et illustrant son implantation dans un local.Fig. 1 is a perspective view showing a chimney established according to the invention (with its glazed cap in the raised loading position) and illustrating its location in a room.

Fig. 2 est une coupe schématique faisant apparaître l'agencement interne de la cheminée suivant fig. 1.Fig. 2 is a schematic section showing the internal arrangement of the chimney according to FIG. 1.

La cheminée représentée comprend un socle creux 1 constitué par un caisson à profil en plan carré, lequel socle est surmonté d'une coiffe relevable 2 à profil polyédrique, en forme de pyramide à quatre faces dans l'exemple de réalisation considéré. Cette coiffe 2 comporte en fait des fers d'armature 2a entre lesquels sont fixées des parois planes 2b transparentes. Entre la base de cette coiffe 2 et la face supérieure du socle 1 est interposé un collecteur d'admission d'air 3 qui s'étend sur le pourtour dudit socle 1 et qui supporte avantageusement une grille 4, ainsi disposée à une certaine hauteur au-dessus de la face supérieure du socle.The chimney shown comprises a hollow base 1 constituted by a box with a profile in square plan, which base is surmounted by a lifting cap 2 with polyhedral profile, in the form of a pyramid with four faces in the embodiment considered. This cap 2 in fact comprises reinforcing bars 2 a between which are fixed transparent walls 2 b . Between the base of this cap 2 and the upper face of the base 1 is interposed an air intake manifold 3 which extends around the periphery of said base 1 and which advantageously supports a grid 4, thus arranged at a certain height above the upper face of the base.

Il convient d'observer que l'un des côtés de la base de la coiffe 2 est articulé au côté correspondant du collecteur 3 par le moyen de compas 5 et d'au moins un ressort compensateur 6. La coiffe 2 est ainsi susceptible d'affecter soit une position basse de fonctionnement (fig. 2) pour laquelle elle définit avec le socle 1 et le collecteur 3 une chambre de combustion 7, soit une position relevée (fig. 1) permettant le chargement en combustible (bois) de ladite chambre 7.It should be observed that one of the sides of the base of the cap 2 is articulated to the corresponding side of the manifold 3 by means of compass 5 and at least one compensating spring 6. The cap 2 is thus capable of assign either a low operating position (fig. 2) for which it defines with the base 1 and the manifold 3 a combustion chamber 7, or a raised position (fig. 1) allowing the loading of fuel (wood) from said chamber 7.

Au niveau de chacune des arêtes du profil pyramidal de la coiffe 2, il est prévu un tube collecteur de fumées 8 dont l'extrémité supérieure s'ouvre au sommet de ladite coiffe, tandis que sa base, légèrement coudée, traverse le collecteur d'admission 3 pour déboucher dans le socle 1. Dans ce socle 1 débouche également un tube inférieur 9, qui, à travers une boîte de ramonage 10, est relié à une gaine verticale 11 pour l'évacuation des fumées, le conduit horizontal 12 ménagé entre le tube 9 et la gaine 11 étant disposé, avec la boîte 10, dans une excavation pratiquée dans le sol du local.At each of the edges of the pyramidal profile of the cap 2, a smoke collecting tube 8 is provided, the upper end of which opens at the top of said cap, while its base, slightly bent, passes through the manifold. inlet 3 to open into the base 1. In this base 1 also opens a lower tube 9, which, through a chimney sweep 10, is connected to a vertical sheath 11 for the evacuation of fumes, the horizontal conduit 12 formed between the tube 9 and the sheath 11 being disposed, with the box 10, in an excavation made in the floor of the room.

De la même manière, on a prévu dans le sol une canalisation 13 dont une extrémité débouche à l'extérieur, tandis que l'extrémité opposée se raccorde à un tube vertical 14. Ce dernier traverse le socle 1 pour déboucher dans le collecteur d'admission 3. La paroi supérieure de ce collecteur 3 est percée de lumières 3a situées au droit de la base de la coiffe 2 afin que l'air lèche les parois transparentes 2b de celle-ci en évitant leur noircissement sous l'effet des fumées ; la paroi verticale de ce collecteur 3 qui est tournée en direction de la grille 4 est elle-même découpée d'au moins une ouverture 3b pour l'admission de l'air comburant à l'intérieur de la chambre de combustion 7.In the same way, a pipe 13 is provided in the ground, one end of which opens to the outside, while the opposite end is connected to a vertical tube 14. The latter crosses the base 1 to open into the collector of inlet 3. the upper wall of the manifold 3 is pierced with ports 3a located in line with the base of the cover 2 so that air licks transparent walls 2 b thereof by avoiding blackening under the influence of fumes; the vertical wall of this manifold 3 which is turned in the direction of the grid 4 is itself cut out by at least one opening 3 b for the admission of the combustion air inside the combustion chamber 7.

Le fonctionnement et l'utilisation de la cheminée ci-dessus décrite se concoivent aisément.The operation and the use of the chimney described above are easily conceived.

Une fois le bois déposé sur la grille 4 et le feu convenablement allumé, la coiffe 2 est rabattue contre le collecteur 3. Les fumées et gaz chauds dégagés par la combustion sont évacués par les collecteurs 8 ; les cendres ramassées au-dessous de la grille 4 peuvent, moyennant démontage d'une trappe centrale 1a du socle 1, être elles-mêmes évacuées à travers la boîte de ramonage 10. L'air neuf admis dans le collecteur 3 se réchauffe lors de son passage dans le socle 1.Once the wood has been placed on the grid 4 and the fire has been properly lit, the cap 2 is folded back against the collector 3. The fumes and hot gases released by the combustion are evacuated by the collectors 8; the ashes collected below the grate 4 may, subject to disassembly of a central hatch 1 a of the base 1, being themselves evacuated through the sweeping box 10. The fresh air admitted into the manifold 3 heats up as it passes through the base 1.

On notera que la combustion est apparente sur les quatres faces de la coiffe 2.It will be noted that the combustion is apparent on the four faces of the cap 2.
