The front of the panel has an embossed design (6, 7, 8) while the rear has a number of parallel hollow ribs extending for its entire length, and connected at both ends to the interior of a hollow rib (12), whose ends preferably protrude beyond the panel. The ribs can be integral with the panel, or formed by pipes welded to it, in the latter case being of semi-cylindrical cross-section extended by a square of rectangular portion.

Description

La présente invention a trait à une plaque de feu ouvert à circulation d'eau pour chauffage d'appoint et, en particulier, à une plaque de feu ouvert conçue et exécutée de manière à se prêter à une accumulation maximum de calories, qu'elle cède à un système tubulaire, qui se trouve en communication avec le chauffage central, tout cela de manière que la chaleur ainsi récupérée s'utilise efficacement au chauffage d'une ou de plusieurs pièces, équipées de radiateurs de chauffage central raccordés à une plaque de feu ouvert du genre concerné.The present invention relates to an open fire plate with circulation of water for auxiliary heating and, in particular, to an open fire plate designed and executed so as to lend itself to a maximum accumulation of calories, which it yields to a tubular system, which is in communication with the central heating, all this so that the heat thus recovered is used effectively for heating one or more rooms, equipped with central heating radiators connected to a plate open fire of the genus concerned.

On sait qu'un feu ouvert s'emploie dans la plupart des cas soit comme élément décoratif, soit pour souligner le caractère intime de la pièce habitée où il est installé, de sorte que, dans le cas le plus favorable, une partie limitée de la chaleur produite s'utilise au chauffage de la pièce, la plus grande partie de la chaleur produite étant évacuée par la cheminée.We know that an open fire is used in most cases either as a decorative element, or to emphasize the intimate character of the living room where it is installed, so that, in the most favorable case, a limited part of the heat produced is used to heat the room, most of the heat produced is removed by the chimney.

On sait, d'autre part, que les frais de chauffage des locaux et, en particulier, les frais de chauffage des pièces d'habitations augmentent constamment. S'y ajoute le fait que la crise énergétique actuelle impose une limitation maximum de la consommation de combustibles minéraux.We know, on the other hand, that the costs of heating the premises and, in particular, the costs of heating the rooms of dwellings are constantly increasing. Added to this is the fact that the current energy crisis imposes a maximum limitation on the consumption of mineral fuels.

Or, la présente invention a pour objet un dispositif de récupération de chaleur facile à prévoir ou à disposer dans un feu ouvert et capable d'accumuler une grande partie de la chaleur y produite par la combustion de bois, de combustibles minéraux ou autres, chaleur qui est ensuite cédée par l'entremise de communications appropriées à l'installation de chauffage central de l'appartement ou de la maison équipée d'un feu ouvert du genre concerné.However, the present invention relates to a heat recovery device easy to predict or to have in an open fire and capable of accumulating a large part of the heat produced there by the combustion of wood, mineral fuels or other, heat which is then transferred via appropriate communications to the central heating installation of the apartment or house equipped with an open fire of the type concerned.

Le dispositif de récupération de chaleur selon la présente invention se compose d'une plaque de feu ouvert à circulation d'eau pour chauffage d'appoint, caractérisée en ce qu'elle se présente sous forme d'une plaque proprement dite dont la paroi frontale accuse un relief prononcé et la paroi dorsale est munie d'une pluralité de nervures parallèles, creuses sur toute leur longueur, dont les creux ou passages se trouvent de part et d'autre en communication avec le creux ou passage d'une nervure creuse, dont les extrémités font de préférence saillie de la partie concernée de la plaque de feu ouvert.The heat recovery device according to the present invention consists of an open fire plate with circulation of water for auxiliary heating, characterized in that it is in the form of a plate proper, the front wall of which shows a pronounced relief and the dorsal wall is provided with a plurality of parallel ribs, hollow over their entire length, the hollows or passages being on either side in communication with the hollow or passage of a hollow rib, the ends of which preferably project from the relevant part of the open fire plate.

Les figures 1 et 2 représentent à titre d'exemple et de manière schématique un feu ouvert 1, équipé à l'arrière d'une plaque de feu ouvert 2 selon l'invention, derrière laquelle est prévue une couche thermo-isolante appropriée 3, telle qu'une couche de laine de roche ou autre.FIGS. 1 and 2 show, by way of example and schematically, an open fire 1, equipped at the rear with an open fire plate 2 according to the invention, behind which is provided an appropriate thermal insulation layer 3, such as a layer of rock wool or the like.

La plaque de feu ouvert employée dans un feu ouvert selon les figures 1 et 2 et illustrée par les figures 3-6, se compose essentiellement d'une plaque frontale 4 de masse appropriée et accusant de préférence une figure en relief prononcé 5, représentant en l'occurrence un écusson 6 accompagné de deux chevaux 7 et 8, qui forment une saillie irrégulière à la surface de la plaque proprement dite 4.The open fire plate used in an open fire according to Figures 1 and 2 and illustrated by Figures 3-6, consists essentially of a front plate 4 of suitable mass and preferably showing a pronounced relief figure 5, representing in the occurrence of a shield 6 accompanied by two horses 7 and 8, which form an irregular projection on the surface of the plate proper 4.

La paroi dorsale de ladite plaque 4 présente une pluralité de nervures verticales 9, qui sont creuses, comme le montre la figure 6, et qui, de part et d'autre, c'est-à-dire en haut et en bas, sont raccordées à une nervure creuse commune, respectivement 10 et 11, et cela de manière que les creux desdites nervures 9 se trouvent en communication avec ceux des nervures 10 et 11.The back wall of said plate 4 has a plurality of vertical ribs 9, which are hollow, as shown in FIG. 6, and which, on either side, that is to say at the top and at the bottom, are connected to a common hollow rib, respectively 10 and 11, and this so that the hollows said ribs 9 are in communication with those of the ribs 10 and 11.

Les extrémités libres des nervures creuses 10 et 11 pourront, le cas échéant, être filetées (filet 12) en vue de l'incorporation de ces dernières dans un réseau de chauffage central.The free ends of the hollow ribs 10 and 11 may, where appropriate, be threaded (thread 12) for the incorporation of the latter into a central heating network.

En effet, on obtient ainsi qu'en présence d'une telle plaque dans un feu ouvert allumé même à faible feu, la plaque 2 absorbe beaucoup de chaleur, qui est transmise à l'eau circulant par les canaux 9, 10 et 11 et est cédée au fluide chauffant en circulation dans l'installation de chauffage central. Ce système présente l'avantage, d'une part, que pendant les demi-saisons le brûleur du chauffage central ne doit pas être allumé, grâce au fait que la chaleur produite par le feu ouvert et récupérée suffit au chauffage d'un nombre relativement important de radiateurs et, d'autre part, qu'en hiver la chaleur ainsi récupérée assure par l'entremise des radiateurs un chauffage d'appoint suffisant pour réduire sensiblement la consommation de combustible du brûleur du chauffage central.In fact, it is thus obtained that in the presence of such a plate in an open fire lit even at low fire, the plate 2 absorbs a lot of heat, which is transmitted to the water circulating through the channels 9, 10 and 11 and is transferred to the heating fluid circulating in the central heating installation. This system has the advantage, on the one hand, that during the half-seasons the central heating burner must not be lit, thanks to the fact that the heat produced by the open fire and recovered is sufficient to heat a relatively large number important of radiators and, on the other hand, that in winter the heat thus recovered provides through the radiators sufficient additional heating to significantly reduce the fuel consumption of the central heating burner.

Inutile de souligner que la présence du relief 5, qui est de forme absolument quelconque, assure une forte absorption et accumulation de chaleur au niveau de la paroi frontale de la plaque, tandis que le relief formé par les nervures 9, 10 et 11 à la paroi dorsale de la plaque 4 y réduit sensiblement les pertes de chaleur, qui sont également limitées par la présence de la couche thermo-isolante 3.Needless to say, the presence of the relief 5, which is of absolutely any shape, ensures a high absorption and accumulation of heat at the front wall of the plate, while the relief formed by the ribs 9, 10 and 11 at the back wall of the plate 4 substantially reduces heat losses, which are also limited by the presence of the heat-insulating layer 3.

Il va de soi que ladite plaque 2 pourra être disposée soit en position verticale, soit en position inclinée vers l'avant dans le feu ouvert, une meilleure absorption et récupération de chaleur étant assurée dans ce dernier cas.It goes without saying that said plate 2 can be arranged either in a vertical position or in a position inclined forward in the open fire, better absorption and heat recovery being ensured in the latter case.

Bien que les conduites 10 et 11 puissent être intercalées par tout moyen approprié dans le circuit d'eau du chauffage central, cette intercalation se fera de préférence de manière à assurer le chauffage de l'eau de retour vers la chaudière et de réduire ainsi au minimum l'apport de chaleur requis pour maintenir la température de l'eau au niveau voulu.Although lines 10 and 11 can be inserted by any suitable means in the heating water circuit central, this intercalation will preferably be done so as to ensure the heating of the water returning to the boiler and thus to minimize the heat input required to maintain the water temperature at the desired level.

La plaque de feu ouvert selon l'invention sera de préférence faite d'un alliage spécial assurant une conduction thermique maximum et une excellente résistance aux heurts à côté d'une dilatation thermique et d'un retrait réduits au minimum.The open fire plate according to the invention will preferably be made of a special alloy ensuring maximum thermal conduction and excellent impact resistance alongside thermal expansion and shrinkage reduced to a minimum.

Il va sans dire que l'invention ne se limite pas à l'exemple d'exécution décrit dans les lignes précédentes et que la plaque concernée se prête à d'innombrables autres modes d'exécution en ce qui concerne sa forme et ses dimensions, soumis à la seule condition que ne soit pas dépassé le cadre de l'invention.It goes without saying that the invention is not limited to the example of execution described in the preceding lines and that the plate concerned lends itself to countless other modes of execution as regards its shape and its dimensions, subject to the sole condition that the scope of the invention is not exceeded.

C'est ainsi, par exemple, comme le montre la figure 4, que le relief 5 peut être formé par des dents horizontales 13, tandis que, comme le montrent les figures 7 et 8, les conduites 9, 10 et 11 pourront être fixées sur la plaque proprement dite 4 par exemple par soudage, au lieu de faire partie intégrante avec elle.Thus, for example, as shown in Figure 4, that the relief 5 can be formed by horizontal teeth 13, while, as shown in Figures 7 and 8, the pipes 9, 10 and 11 can be fixed on the actual plate 4 for example by welding, instead of being integral with it.

La figure 7 représente un mode d'exécution caractérisé en ce que les conduites 9, 10 et 11 sont des tubes de section circulaire, tandis que la figure 8 représente un mode d'exécution selon lequel les tubes ont une section semi-circulaire et semi-carrée ou semi-rectangulaire. Les tubes 9, 10 et 11 pourront évidemment avoir toute autre forme appropriée.FIG. 7 represents an embodiment characterized in that the pipes 9, 10 and 11 are tubes of circular section, while FIG. 8 represents an embodiment according to which the tubes have a semi-circular and semi-section - square or semi-rectangular. The tubes 9, 10 and 11 may obviously have any other suitable shape.

Les figures 9, 10 et 11 montrent que ladite plaque de feu ouvert selon l'invention pourra être adaptée de toute manière appropriée au feu ouvert. C'est ainsi, par exemple dans le cas de la figure 1, que la hotte pourra être combinée ou non avec une plaque selon l'une ou l'autre des figures 3, 9 ou 10 ou selon une combinaison des figures 9 et 10.Figures 9, 10 and 11 show that said open fire plate according to the invention can be adapted in any way suitable for open fire. Thus, for example in the case of Figure 1, the hood can be combined born or not with a plate according to either of Figures 3, 9 or 10 or according to a combination of Figures 9 and 10.

On voit donc que l'invention ne se limite pas à l'une ou l'autre des plaques selon la description précédente et les dessins annexés, mais en prévoit des modifications, additions et adaptations extrêmement variées, soumises à la condition de respecter son principe fondamental et de ne pas dépasser ses limites, définies dans les revendications ci-après formulées.It can therefore be seen that the invention is not limited to one or the other of the plates according to the preceding description and the attached drawings, but provides for extremely varied modifications, additions and adaptations, subject to the condition of respecting its principle fundamental and not to exceed its limits, defined in the claims below.
