Abstract
Description
La présente invention concerne le domaine des dispositifs de chauffage de locaux, en particulier des che minées-poeles, et a pour objet un foyer de telles cheminées muni d'un dispositif de tirage inversé. The present invention relates to the field of premises heating devices, in particular chimneys-stoves, and relates to a hearth of such fireplaces provided with an inverted draft device.
Les foyers de cheminée de ce type existant actuellement présentent généralement une sortie de fumée à leur partie supérieure à réglage d'ouverture au moyen d'un clapet de tirage, ainsi qu'une porte vitrée de fermeture du foyer, et un ou plusieurs orifices de tirage disposes à l'avant du foyer. La récupération de chaleur s'effectue au moyen de gaines ou de chicanes entourant l'âtre et reliées à leur partie inférieure à une ouverture d'entrée d'air à chauffer, et à leur partie supérieure à une ou plusieurs ouvertures de sortie d'air chaud. Fireplaces of this type currently existing generally have a smoke outlet at their upper part with opening adjustment by means of a draft valve, as well as a glass door for closing the fireplace, and one or more orifices for draw arranged at the front of the fireplace. Heat recovery takes place by means of sheaths or baffles surrounding the hearth and connected at their lower part to an air inlet opening to be heated, and at their upper part to one or more air outlet openings. hot air.
Ces foyers connus permettent ltobtention d'un rendement thermique amélioré par rapport aux cheminées à foyer ouvert. Mais cependant, du fait de la sortie verticale des gaz chauds, les déperditions restent encore importantes, notamment en périodes de chauffage réduit. These known fireplaces allow obtaining an improved thermal efficiency compared to open fireplaces. However, due to the vertical outlet of the hot gases, the losses are still significant, especially during periods of reduced heating.
La présente invention a pour but de pallier ces inconvénients. The present invention aims to overcome these drawbacks.
Elle a, en effet, pour objet un foyer fermé, en particulier de cheminée-poêle, caractérisé en ce qu'il est muni d'un dispositif de tirage inverse constitué par un caisson disposé sous la grille foyère et logeant le cendrier, et par un conduit de fumée secondaire s'étendant derrière autre et raccordé, d'une part, à sa partie inférieure, au caisson, et, d'autre part, à sa partie supérieure au conduit de fumée du foyer, au dessus du clapet de fermeture de ce dernier. It has, in fact, for its object a closed hearth, in particular a chimney-stove, characterized in that it is provided with a reverse drawing device constituted by a box placed under the hearth grate and housing the ashtray, and by a second flue extending behind another and connected, on the one hand, to its lower part, to the casing, and, on the other hand, to its upper part to the flue of the fireplace, above the shut-off valve of the last.
L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dans lequel
La figure 1 est.une vue en élevation latérale et en coupe d'un foyer conforme à l'invention, et
La figure 2 est une vue en élevation frontale du foyer suivant la figure 1.The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, in which
FIG. 1 is a side elevation view in section of a hearth according to the invention, and
FIG. 2 is a front elevation view of the hearth according to FIG. 1.
Conformément à l'invention, et comme le montrent, à titre d'exemple, les figures 1 et 2 du dessin annexé, le foyer fermé, en particulier de cheminée-poêle, est muni d'un dispositif 1 de tirage inversé, qui est essentiellement constitué par un caisson 2 s'étendant sous la grille foyers, et par un conduit de fumée secondaire 3 s'étendant verticalement.derrière autre et raccordé au caisson 2, à sa partie inférieure, et, à sa partie supérieure au conduit de fumée 4 du foyer. In accordance with the invention, and as shown, by way of example, in FIGS. 1 and 2 of the appended drawing, the closed hearth, in particular of a chimney-stove, is provided with a device 1 for reverse draft, which essentially constituted by a box 2 extending under the hearth grid, and by a second smoke duct 3 extending vertically. behind other and connected to the box 2, at its lower part, and, at its upper part to the smoke duct 4 of the foyer.
Le raccordement du conduit 3 au conduit 4 est avantageusement effectue au-déssus du clapet 5 de fermeture du conduit 4, de sorte qu'une simple manoeuvre de ce clapet 5 en position de fermeture a pour effet de provoquer le fonctionnement du foyer en tirage inversé (position représentée à la figure 1-). En effet, dans une telle position de fermeture du clapet 5, les fumées chaudes sont obligées de passer dans le caisson 2 pour rejoindre, à travers le conduit de fumée secondaire 3, le conduit de fumée 4 du foyer, de sorte que leur cheminement est allongé et que la récupération de la chaleur de ces fumées peut être améliorée. The connection of the conduit 3 to the conduit 4 is advantageously carried out above the valve 5 for closing the conduit 4, so that a simple operation of this valve 5 in the closed position has the effect of causing the fireplace to operate in reverse draft. (position shown in Figure 1-). Indeed, in such a closed position of the valve 5, the hot fumes are forced to pass into the box 2 to join, through the secondary smoke duct 3, the smoke duct 4 of the hearth, so that their path is elongated and that the heat recovery from these fumes can be improved.
Selon une autre caractéristique de l'invention, pour augmenter davantage la récupération de chaleur, le caisson 2, qui loge à sa partie inférieure le cendrier 10, est traversé par des nappes de tuyaux 6 disposés en quinconque et reliés à leurs extrémités à des chambres collectrices 7, dont l'une est reliée par un manchon 8 à une turbine de propulsion d'air (non représentée), et dont l'autre est reliée par un manchon 8' à une ou plusieurs tubulures ou gaines de distribution d'air chaud. According to another characteristic of the invention, to further increase heat recovery, the box 2, which houses the ashtray 10 at its lower part, is crossed by plies of pipes 6 arranged in staggered rows and connected at their ends to chambers manifolds 7, one of which is connected by a sleeve 8 to an air propulsion turbine (not shown), and the other of which is connected by a sleeve 8 'to one or more air distribution pipes or ducts hot.
A sa partie avant, le foyer est pourvu, de manière connue, d'orifices 9 d'arrivée d'air frais à ouverture réglable. Ces orifices 9 sont particulièrement intéressants en position de marche à tirage inversé, dans laquelle il se créé un courant d'air orienté en direction du conduit 3. At its front part, the hearth is provided, in known manner, with openings 9 for fresh air with adjustable opening. These orifices 9 are particularly advantageous in the reverse draft position, in which a flow of air is created which is directed towards the duct 3.
Dans une telle marche, à tirage inversé, les tuyaux 6 sont réchauffés très intensément et très rapidement, de sorte que l'air s'y trouvant est également, rapidement, porté à haute température, et que par circulation de cet air une récupération maximale de la chaleur est obtenue. In such a reverse-draft operation, the pipes 6 are heated very intensely and very quickly, so that the air therein is also, quickly, brought to high temperature, and that by circulation of this air maximum recovery heat is obtained.
En outre, dans cette position de chauffage, la consommation de combustible est réduite à un minimum, du fait que la combustion est plus lente et s1 effectue pratiquement sans flamme. Furthermore, in this heating position, the fuel consumption is reduced to a minimum, because the combustion is slower and takes place practically without flame.
Pour le fonctionnement normal du foyer, en marche libre, il suffit à l'utilisateur de pivoter le clapet 5 en position d'ouverture (traits mixtes fins), dans laquelle le tirage s'gfectue normalement, les fumées et gaz chauds s'échappent verticalement à travers le conduit 4. For the normal operation of the fireplace, in free operation, the user just has to pivot the valve 5 to the open position (thin mixed lines), in which the draft is normal, the smoke and hot gases escape vertically through the conduit 4.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. 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 embodiment described and shown in the accompanying drawing. 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.
