Description

L'invention a pour objet un foyer de cheminée permettant de récupérer la chaleur radiante de ses parois et de sa base.The subject of the invention is a fireplace hearth making it possible to recover the radiant heat from its walls and from its base.

On a déjà proposé de faire passer dans le foyer d'une cheminée, une conduite d'eau sous forme d'un serpentin de cuivre pour la production d'eau chaude. Toutefois, une telle conduite exposée au feu ou au contact des braises subit des détériorations rapides. D'autre part, la quantité de chaleur récupérée ainsi est faible.It has already been proposed to pass a water pipe in the form of a copper coil through the fireplace hearth for the production of hot water. However, such a pipe exposed to fire or in contact with embers undergoes rapid deterioration. On the other hand, the amount of heat recovered in this way is low.

Afin de remédier à ces inconvénients, le foyer de cheminée selon l'invention est caractérisé en ce qu'il comprend au moins un circuit de fluide dans sa base et dans une de ses parois.In order to remedy these drawbacks, the fireplace hearth according to the invention is characterized in that it comprises at least one fluid circuit in its base and in one of its walls.

De préférence, la base et le fond de la cheminée sont constitués par des plaques de fonte présentant dans leur face dorsale des cannelures dans lesquelles est logé un serpentin destiné au passage d'un liquide. Les plaques de fonte agissant comme accumulateur de chaleur transfèrent la chaleur au serpentin par contact, d'une façon plus régulière et protègent simultanément le serpentin de toute détérioration éventuelle due au contact avec des braises,à l'exposition au feu ou à des chocs thermiques.Preferably, the base and the bottom of the chimney are constituted by cast iron plates having in their dorsal face grooves in which is housed a coil intended for the passage of a liquid. The cast iron plates acting as a heat accumulator transfer heat to the coil by contact, in a more regular way and simultaneously protect the coil from any possible deterioration due to contact with embers, exposure to fire or thermal shock. .

Le dessin annexé représente schématiquement et à titre d'exemple une forme d'exécution du foyer, objet de l'invention et des variantes.

La cheminée représentée à la figure 1 comprend un foyer dont la base est constituée par une plaque de fonte (1) présentant sur sa face inférieure deux cannelures e, 3) en forme de serpentins, dans lesquelles sont logés deux serpentins de cuivre d'une conduite d'eau (voir fig. 2). Cette plaque de fonte (1) repose sur une seconde plaque de fonte (4) présentant sur sa face inférieure des nervures (5) (voir fig. 3). Une double plaque de tôle (6) appliquée contre les nervures (5) de la plaque de fonte (4), délimite un passage d'entrée d'air (7) qui circule entre les nervures (5) de la plaque de fonte (4) au contact de laquelle l'air s'échauffe.The chimney shown in Figure 1 includes a hearth whose base is constituted by a cast iron plate (1) having on its underside two grooves e, 3) in the form of coils, in which are housed two copper coils of a water pipe (see fig. 2). This cast iron plate (1) rests on a second cast iron plate (4) having ribs (5) on its underside (see fig. 3). A double sheet metal plate (6) applied against the ribs (5) of the cast iron plate (4), delimits an air inlet passage (7) which circulates between the ribs (5) of the cast iron plate ( 4) on contact with which the air is heated.

Le fond du foyer comprend également une plaque de fonte(1 a) présentant au dos deux cannelures en forme de serpentins dans lesquelles se prolongent les serpentins de cuivre de la conduite d'eau. Cette plaque de fonte (1 a) est appliquée contre une plaque de fonte (4 a), munie au dos de nervures (5) contre lesquelles est appliquée une plaque de tôle (8). Ainsi, l'air, après avoir circulé entre les nervures (5) de la plaque de fonte (4), circule ensuite entre les nervures (5) de la plaque (4 a), au contact de laquelle il continue de s'échauffer avant de s'échapper par une ouverture (9) pratiquée au voisinage de la hotte (10) de la cheminée. Cet air chaud permet d'augmenter la température ambiante de la pièce dans laquelle se trouve la cheminée. Eventuellement, on pourrait brancher cette ouverture (9) sur un conduit destiné à réchauffer une pièce voisine. L'eau chaude amenée à la base de la hotte (10) par les serpentins pris entre les plaques de fonte (1 a et 4 a), passe ensuite dans un serpentin pris entre deux plaques de fonte ajourées (11) disposées parallèlement à la base (1) du foyer à l'entrée de la hotte. Une des plaques (11) présente, sur sa face en regard de l'autre, des cannelures (21) dans lesquelles ce serpentin est logé (voir fig. 4). Les parties ajourées (12) des plaques (11), permettent le passage de la fumée du foyer dans la hotte (10). Simultanément, le serpentin pris entre les plaques de fonte (11) bénéficie d'un apport de chaleur.supplémentaire qui échauffe l'eau qui le traverse.The bottom of the hearth also includes a cast iron plate (1 a) having on the back two grooves in the form of coils in which the copper coils of the water pipe extend. This cast iron plate (1 a) is applied against a cast iron plate (4 a), provided on the back with ribs (5) against which a sheet metal plate (8) is applied. Thus, the air, after having circulated between the ribs (5) of the cast iron plate (4), then circulates between the ribs (5) of the plate (4 a), in contact with which it continues to heat up. before escaping through an opening (9) made in the vicinity of the hood (10) of the chimney. This hot air increases the ambient temperature of the room in which the chimney is located. Optionally, this opening (9) could be connected to a duct intended to heat a neighboring room. Hot water brought to the base of the hood (10) by the coils taken between the cast iron plates (1 a and 4 a), then passes through a coil taken between two perforated cast iron plates (11) arranged parallel to the base (1) of the hearth at the entrance to the hood. One of the plates (11) has, on its face opposite the other, grooves (21) in which this coil is housed (see fig. 4). The openwork parts (12) of the plates (11) allow the passage of smoke from the hearth into the hood (10). Simultaneously, the coil caught between the cast iron plates (11) benefits from an additional heat supply which heats the water passing through it.

Selon la variante représentée à la figure 5, le serpentin disposé dans le prolongement des serpentins pris entre les plaques de fonte (1 a et 4 a), peut être pris entre des plaques de fonte non ajourées (11a) fixées au fond de la hotte. Une des plaques (11 a) présente sur sa face en regard de l'autre, des cannelures dans lesquelles ce serpentin est logé.According to the variant shown in Figure 5, the coil arranged in the extension of the coils taken between the cast iron plates (1 a and 4 a), can be caught between non-perforated cast iron plates (11a) fixed to the bottom of the hood . One of the plates (11a) has on its face opposite the other, grooves in which this coil is housed.

De nombreuses autres variantes peuvent être envisagées. Par exemple, les parois latérales du foyer peuvent également être re- couvertes d'un assemblage de plaques de fonte (1 a et 4 a) pour le chauffage de l'air et de l'eau. Il en est de même des parois latérales et frontales de la hotte qui pourraient être garnies de plaques de fonte (11 a) dans lesquelles seraient pris des serpentins alimentés en eau.Many other variants can be envisaged. For example, the side walls of the fireplace can also be covered with an assembly of cast iron plates (1 a and 4 a) for heating air and water. It is the same for the side and front walls of the hood which could be lined with cast iron plates (11a) in which would be taken coils supplied with water.

On a représenté à la figure 6 un schéma d'une installation de chauffage en circuit fermé, branché sur la cheminée représentée à la figure 5. Toutefois le circuit d'eau a été remplacé par un circuit d'huile (13) branché sur un réservoir (14) comprenant un chauffe eau (15) d'une part et un serpentin (16) pour l'alimentation d'appareils (17) de chauffage d'ambiance. On a uniquement représenté à cette figure les serpentins pris entre les plaques de fonte 1-4 et la-4a et le serpentin pris dans les plaques de fonte non ajourées (11 a) qui font partie du circuit d'huile (13) branché sur le réservoir d'huile (14). Une pompe de circulation (18) permet de faire circuler l'huile du réservoir (14) dans les serpentins pris dans les plaques de fonte (1-4, la-4a et lla) représentées à la fig. 5, en circuit fermé, ce qui permet d'élever la température de l'huile contenue dans le réservoir (14) pour autant qu'un feu soit allumé dans la cheminée. Cette chaleur est ensuite retransmise par l'huile du réservoir (14) à un serpentin (16) contenant de l'eau additionnée ou non d'un produit antigel qui circule en circuit fermé entre le serpentin (16) et un radiateur (17) grâce à une pompe de circulation (19). Il est ainsi possible de chauffer une ou plusieurs pièces attenantes à la pièce où est installée la cheminée au moyen d'un ou plusieurs radiateurs (17). Simultanément, une partie de la chaleur est retransmise par l'huile à de l'eau contenue dans le chauffe eau (15) qui est branché directement sur la canalisation (20) d'amenée d'eau aux radiateurs (17) et aux appareils sanitaires non représentés.There is shown in Figure 6 a diagram of a closed circuit heating installation, connected to the chimney shown in Figure 5. However the water circuit has been replaced by an oil circuit (13) connected to a tank (14) comprising a water heater (15) on the one hand and a coil (16) for supplying appliances (17) for space heating. We have only shown in this figure the coils taken between the cast iron plates 1-4 and la-4a and the coil taken in the non-perforated cast iron plates (11 a) which are part of the oil circuit (13) connected to the oil tank (14). A pump circulation (18) makes it possible to circulate the oil from the reservoir ( 14 ) in the coils taken in the cast iron plates (1-4, la-4a and lla) shown in fig. 5, in a closed circuit, which makes it possible to raise the temperature of the oil contained in the tank (14) provided that a fire is started in the chimney. This heat is then transmitted by the oil from the reservoir (14) to a coil (16) containing water, whether or not added with an antifreeze product, which circulates in a closed circuit between the coil (16) and a radiator (17). thanks to a circulation pump (19). It is thus possible to heat one or more rooms adjoining the room where the chimney is installed by means of one or more radiators (17). At the same time, part of the heat is transmitted by the oil to the water contained in the water heater (15) which is connected directly to the pipe (20) supplying water to the radiators (17) and to the appliances. sanitary facilities not shown.

De nombreuses variantes de l'installation représentée à la figure 6 peuvent être envisagées. Entre autres, le circuit d'huile peut être remplacé par un circuit d'eau; le circuit de chauffage des radiateurs (17) peut être interrompu tout en maintenant le circuit de chauffage de l'eau contenue dans le chauffe eau (15). Alternativement encore, le circuit (13) peut être branché directement sur un ou plusieurs radiateurs (17). Dans ce cas, le réservoir (14) et le chauffe eau (15) sont supprimés.Many variants of the installation shown in Figure 6 can be considered. Among other things, the oil circuit can be replaced by a water circuit; the heating circuit of the radiators (17) can be interrupted while maintaining the heating circuit of the water contained in the water heater (15). Alternatively again, the circuit (13) can be connected directly to one or more radiators (17). In this case, the tank (14) and the water heater (15) are eliminated.
