Description

La présente invention concerne le domaine des poêles munis d'une vitre et des cheminées à foyer fermé, et a pour objet un procédé de désenfumage d'une telle vitre de poêle ou de cheminée à foyer fermé.The present invention relates to the field of stoves fitted with a glass pane and closed hearth fireplaces, and relates to a method of smoke extraction from such pan glass or closed hearth fireplace.

L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé.The invention also relates to a device for implementing this method.

Actuellement, les vitres équipant les poêles et les cheminées à foyer fermé sont généralement noircies par la fumée après un délai d'utilisation relativement court, du fait que la fumée tend à lècher ladite vitre, favorisant ainsi un dépôt de suie, qui forme une croûte opaque sous l'effet de la chaleur.Currently, the windows fitted to stoves and closed fireplaces are generally blackened by smoke after a relatively short period of use, because the smoke tends to lick said window, thus promoting a deposit of soot, which forms a crust opaque under the effect of heat.

La présente invention a pour but de pallier cet inconvénient.The object of the present invention is to overcome this drawback.

Elle a, en effet, pour objet un procédé de désenfumage d'une vitre de poêle ou de cheminée à foyer fermé, caractérisé en ce qu'il consiste essentiellement à réaliser, par utilisation de la dépression créée par le foyer, une circulation d'air parallèlement à la vitre, de manière à en écarter la fumée, cet air étant introduit sur tout le pourtour de la vitre à travers une fente périphérique étroite permettant une accélération de l'air.It has, in fact, for its object a process for smoke extraction from a stove or chimney window with a closed hearth, characterized in that it essentially consists in carrying out, by using the depression created by the hearth, a circulation of air parallel to the window, so as to spread the smoke, this air being introduced around the entire periphery of the window through a narrow peripheral slot allowing an acceleration of the air.

L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé, caractérisé en ce qu'il est constitué par un cadre-cornière de support de la vitre, dans lequel la vitre est montée à dilatation libre au moyen de plots munis de joints élastiques, et par un contre-cadre délimitant une fente périphérique avec le cadre-cornière de support de la vitre.The invention also relates to a device for the implementation of this method, characterized in that it is constituted by an angle-bracket for supporting the glass, in which the glass is mounted in free expansion by means of studs. provided with elastic seals, and by a counter-frame delimiting a peripheral slot with the angle-bracket for supporting the glass.

Conformément à une variante de réalisation de l'invention, la vitre détermine avec les parois avant du foyer une fente périphérique d'entrée d'air.According to an alternative embodiment of the invention, the window determines with the front walls of the hearth a peripheral air inlet slot.

Selon une autre variante de réalisation de l'invention, dans le cas d'utilisation d'une vitre montée dans le cadre-cornière au moyen d'un support continu, la partie inférieure du cadre-cornière est munie de fentes calibrées d'entrée d'air.According to another alternative embodiment of the invention, in the case of using a window mounted in the angle frame by means of a continuous support, the lower part of the angle frame is provided with calibrated entry slots of air.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est un schéma de principe expliquant le procédé conforme à l'invention suivant un mode de réalisation possible du dispositif de mise en oeuvre de ce procédé ;
  • la figure 2 est une vue en coupe d'une variante de réalisation du dispositif ;
  • la figure 3 est une vue en plan de la vitre montée dans le dispositif suivant la figure 2, et
  • la figure 4 est une vue partielle en coupe d'un autre mode de réalisation du dispositif conforme à l'invention.
The invention will be better understood thanks to the description below, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a block diagram explaining the method according to the invention according to a possible embodiment of the device for implementing this method;
  • Figure 2 is a sectional view of an alternative embodiment of the device;
  • FIG. 3 is a plan view of the window mounted in the device according to FIG. 2, and
  • Figure 4 is a partial sectional view of another embodiment of the device according to the invention.

Conformément à l'invention, et comme le montre plus particulièrement, à titre d'exemple, la figure 1 des dessins annexés, le procédé de désenfumage d'une vitre de poêle ou de cheminée à foyer fermé consiste essentiellement à réaliser, par utilisation de la dépression créée par le foyer, une circulation d'air 1 parallèlement à la vitre 2, de manière à en écarter la fumée. Cet air est introduit sur tout le pourtour de la vitre 2 à travers une fente périphérique étroite 3, qui permet une accélération de l'air. Grâce à cette accélération, l'air entre en lèchant la vitre sur une longueur suffisante pour que la fumée soit écartée de la vitre 2, de sorte que cette dernière reste claire et que l'utilisateur puisse profiter du spectacle des flammes.According to the invention, and as shown more particularly, by way of example, FIG. 1 of the appended drawings, the method of smoke extraction from a stove or closed fireplace glass essentially consists in carrying out, by using the depression created by the hearth, an air circulation 1 parallel to the window 2, so as to spread the smoke. This air is introduced over the entire periphery of the window 2 through a narrow peripheral slot 3, which allows the air to accelerate. With this acceleration, the air enters by licking the window over a sufficient length for the smoke to be removed from the window 2, so that the latter remains clear and the user can enjoy the spectacle of flames.

Le schéma de la figure 1 représente un premier mode de réalisation possible d'un dispositif pour la mise en oeuvre de ce procédé. En effet, dans cette réalisation, la vitre 2 est suspendue à un cadre non représenté, et la fente 3 est délimitée par le jeu existant entre la vitre 2 et les parois avant 4 du foyer 5.The diagram in FIG. 1 represents a first possible embodiment of a device for the implementation of this method. In fact, in this embodiment, the window 2 is suspended from a frame not shown, and the slot 3 is delimited by the play existing between the window 2 and the front walls 4 of the hearth 5.

Les figures 2 et 3 représentent une variante de réalisation de l'invention, dans laquelle le dispositif est constitué par un cadre-cornière 6 de support de la vitre 2', dans lequel la vitre 2' est montée à dilatation libre au moyen de plots 7 munis de joints élastiques non représentés (figure 3), et par un contre-cadre 8 délimitant une fente périphérique 9 avec le cadre-cornière 6. Les plots 7 sont avantageusement au nombre de quatre et permettent une dilatation différentielle des bords de la vitre 2' et du cadre 6., ainsi qu'un décollement de la vitre 2' du cadre 6 (figure 2), ménageant sur tout le pourtour de la vitre une entrée d'air 9', qui est dévié par l'aile de la cornière formant le contre-cadre 8 suivant un plan parallèle à la vitre 2'. Dans ce mode de réalisation, il est réalisé une double fente périphérique 9-9' autour de la vitre 2'.Figures 2 and 3 show an alternative embodiment of the invention, in which the device consists of an angle frame 6 for supporting the glass 2 ', in which the glass 2' is mounted in free expansion by means of studs 7 provided with elastic seals, not shown (FIG. 3), and by a counter-frame 8 delimiting a peripheral slot 9 with the angle bracket 6. The studs 7 are advantageously four in number and allow differential expansion of the edges of the glass 2 'and of the frame 6., as well as a detachment of the window 2' from the frame 6 (FIG. 2), providing around the entire periphery of the window an air inlet 9 ', which is deflected by the wing of the angle iron forming the counter-frame 8 along a plane parallel to the window 2 '. In this embodiment, a double peripheral slot 9-9 'is produced around the window 2'.

La figure 3 représente une autre variante de réalisation de l'invention, dans laquelle la vitre 2" est montée dans le cadre-cornière 6', au moyen d'un support continu non représenté. Dans ce cas, la partie inférieure 10 du cadre-cornière 6' est munie de fentes calibrées 11 d'entrée d'air.FIG. 3 represents another alternative embodiment of the invention, in which the window 2 "is mounted in the angle frame 6 ', by means of a continuous support not shown. In this case, the lower part 10 of the frame -rounder 6 'is provided with calibrated slots 11 for air intake.

Grâce à l'invention, il est possible de réaliser une circulation d'air devant la vitre, à l'intérieur du foyer, de manière à éviter l'encrassement de ladite vitre.Thanks to the invention, it is possible to carry out air circulation in front of the glass, inside the hearth, so as to avoid fouling of said glass.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
