Description

La présente invention a pour objet un dispositif de chaudière d'âtre.The present invention relates to a boiler device hearth.

Un dispositif de chaudière d'âtre consiste en une chaudière installée dans une cheminée à bois, comportant un échangeur à fluide caloporteur permettant de récupérer la chaleur produite par le feu et de la transmettre à un ou plusieurs radiateurs.A hearth boiler device consists of a boiler installed in a wood-burning fireplace, comprising a heat exchanger heat transfer fluid to recover the heat produced by fire and transmit it to one or more radiators.

La plupart des dispositifs de chaudière d'âtre sont à combustion contrôlée, c'est-à-dire qu'une turbine accélère la combustion et crée un effet de forge pour faire monter la température de l'échangeur, et lorsque l'eau a atteint la température désirée dans l'échangeur, ladite turbine s'arrête et le registre se ferme.Most hearth boiler devices are at controlled combustion, i.e. a turbine accelerates the combustion and creates a forge effect to raise the heat exchanger temperature, and when the water has reached the desired temperature in the exchanger, said turbine stops and the registry closes.

En pratique, l'échangeur est disposé au niveau du foyer et le fluide caloporteur circule dans des tuyaux, sous l'action d'un circulateur, vers un ou plusieurs radiateurs.In practice, the exchanger is arranged at the hearth and the heat transfer fluid circulates in pipes, under the action of a circulator, to one or more radiators.

L'échangeur peut être placé soit dans la paroi arrière du foyer, soit au-dessus de ce dernier, dans l'avaloir par exemple.The exchanger can be placed either in the rear wall of the focus, either above the latter, downstream by example.

Les dispositifs de chaudière d'âtre existants présentent l'inconvénient de ne pas permettre une récupération optimale des calories dégagées par les produits de combustion, avec pour conséquence un fonctionnement prolongé de la turbine et donc une consommation accrue de combustible.Existing hearth boiler devices present the disadvantage of not allowing optimal recovery calories released by combustion products, with for consequence of a prolonged operation of the turbine and therefore increased fuel consumption.

D'autre part, les dispositifs existants sont constitués de tubes agencés en un serpentin qui est de conception complexe donc coûteuse. On the other hand, the existing devices consist of tubes arranged in a serpentine which is of complex design therefore expensive.

La présente invention a pour but de proposer un dispositif de chaudière d'âtre de conception simple permettant de remédier à ces divers inconvénients.The object of the present invention is to propose a device for hearth boiler of simple design allowing to remedy these various drawbacks.

Le dispositif de chaudière d'âtre objet de la présente invention se caractérise essentiellement en ce qu'il comporte un avaloir dont deux parois en vis-à-vis sont doubles pour former deux réservoirs destinés à être remplis d'eau, et reliées entre elles par des tubes espacés s'étendant au-dessus du foyer, lesdites parois doubles étant connectées à un circuit d'eau, l'une comportant une arrivée d'eau et l'autre une sortie.The hearth boiler device object of this invention is essentially characterized in that it comprises a gully with two opposite walls that are double for form two reservoirs intended to be filled with water, and interconnected by spaced tubes extending above of the hearth, said double walls being connected to a circuit one with a water inlet and the other with a exit.

L'eau circule d'une paroi double à l'autre par les tubes qui sont chauffés par les produits de combustion, le dispositif selon l'invention est d'autre part de conception simple et de réalisation peu coûteuse.The water circulates from a double wall to the other through the tubes which are heated by the products of combustion, the device according to the invention is on the other hand of simple design and inexpensive realization.

On notera que de préférence, les parois doubles sont les parois avant et arrière de l'avaloir et que l'arrivée d'eau est placée à la base de la paroi arrière tandis que la sortie est réalisée au niveau de la partie haute de cette même paroi arrière.Note that preferably the double walls are the walls front and rear of the drain and the water inlet is placed at the base of the rear wall while the exit is made at the top of the same rear wall.

Selon une caractéristique additionnelle du dispositif selon l'invention, les tubes sont répartis en deux ensembles disposés de part et d'autre d'une région médiane de l'avaloir, les tubes de chacun desdits ensembles étant disposés les uns à côté des autres et les uns au-dessus des autres en quinconce, tandis que chacun desdits ensembles est bordé latéralement du côté de ladite région médiane d'un déflecteur.According to an additional characteristic of the device according to the invention, the tubes are divided into two sets arranged on either side of a middle region of the outlet, the tubes of each of said assemblies being arranged one next to the others and one above the other staggered, while each of said assemblies is bordered laterally on the side of said middle region of a deflector.

Selon une autre caractéristique additionnelle du dispositif selon l'invention, chacun des déflecteurs est disposé incliné dans le sens opposé à celui de la paroi qui borde de l'autre côté l'ensemble de tubes. According to another additional characteristic of the device according to the invention, each of the deflectors is arranged inclined in the opposite direction to that of the wall that borders on the other side of the tube set.

Les déflecteurs permettent de retenir les produits de combustion, et lorsqu'ils sont inclinés, ils forment avec les parois de l'avaloir deux hottes qui ralentissent lesdits produits de combustion ce qui accroít l'échauffement des tubes.The deflectors make it possible to retain the products of combustion, and when tilted, they form with the walls of the outlet two hoods which slow down said combustion products which increases the heating of the tubes.

Selon une autre caractéristique additionnelle du dispositif selon l'invention, les tubes dans chacun des ensembles sont placés de manière à former, en section transversale, un triangle bordé latéralement par une paroi de l'avaloir et de l'autre par un déflecteur.According to another additional characteristic of the device according to the invention, the tubes in each of the assemblies are placed so as to form, in cross section, a triangle bordered laterally by a wall of the drain and the other by a deflector.

Selon une autre caractéristique additionnelle du dispositif selon l'invention, pour chacun des ensembles de tubes, le déflecteur est accroché sur un tube, et maintenu écarté desdits tubes par une entretoise.According to another additional characteristic of the device according to the invention, for each of the sets of tubes, the deflector is hung on a tube, and kept away from said tubes by a spacer.

Selon une autre caractéristique additionnelle du dispositif selon l'invention, les bases des deux déflecteurs sont reliées par une plaque amovible qui s'étend dans la région médiane de l'avaloir au-dessus du foyer.According to another additional characteristic of the device according to the invention, the bases of the two deflectors are connected by a removable plate which extends in the middle region of have it over the hearth.

La plaque permet de diriger tous les produits de combustion vers les deux hottes formées par les déflecteurs et les parois de l'avaloir, ce qui accroít encore l'échauffement des tubes.Plate allows directing of all combustion products towards the two hoods formed by the deflectors and the walls to swallow it, which further increases the heating of the tubes.

Selon une autre caractéristique additionnelle du dispositif selon l'invention, l'eau qui alimente l'une des parois doubles provient d'un échangeur plan placé verticalement à l'arrière du foyer.According to another additional characteristic of the device according to the invention, the water which feeds one of the double walls comes from a flat exchanger placed vertically at the rear of the foyer.

L'échangeur plan, qui est optionnel, permet de préchauffer l'eau qui est ensuite dirigée vers l'une des parois doubles. The planar heat exchanger, which is optional, allows preheating the water which is then directed to one of the double walls.

Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which relates to the attached drawing, which represents a non-limiting embodiment.

Dans le dessin annexé :

  • la figure 1 représente une vue en coupe selon un plan vertical de l'avaloir d'un dispositif de chaudière d'âtre selon l'invention.
  • la figure 2 représente une vue en élévation d'une partie du même dispositif.
In the attached drawing:
  • Figure 1 shows a sectional view along a vertical plane of the inlet of a hearth boiler device according to the invention.
  • Figure 2 shows an elevational view of part of the same device.

Si on se réfère à la figure 1, on peut voir les deux parois latérales 10 et 11 de l'avaloir 1 d'un dispositif de chaudière d'âtre selon l'invention, ainsi que la paroi arrière 12 de celui-ci, la paroi avant n'étant pas visible.If we refer to Figure 1, we can see the two walls side 10 and 11 of the outlet 1 of a boiler device hearth according to the invention, as well as the rear wall 12 of this one, the front wall not being visible.

La paroi avant et la paroi arrière 12 sont des parois doubles, de manière à constituer des réservoirs plans. Elles sont reliées par des tubes 20 et 30 qui communiquent chacun avec les deux réservoirs.The front wall and the rear wall 12 are double walls, so as to constitute flat tanks. They are connected by tubes 20 and 30 which each communicate with the two tanks.

Les tubes 20 et 30 sont regroupés en deux ensembles respectivement 2 et 3, disposés chacun de part et d'autre de la région médiane de l'avaloir 1, contre les parois latérales 10 et 11.Tubes 20 and 30 are grouped into two sets respectively 2 and 3, each arranged on either side of the middle region of the outlet 1, against the side walls 10 and 11.

Dans chacun des ensembles 2 et 3, les tubes 20 et 30 sont disposés côte à côte et superposés en quinconce, de manière à former en section transversale un triangle bordé d'un côté par une paroi latérale 10 ou 11. In each of sets 2 and 3, tubes 20 and 30 are arranged side by side and staggered so as to form in cross section a triangle bordered on one side by a side wall 10 or 11.

L'autre côté de chacun des ensembles 2 et 3 est bordé par une plaque, ou déflecteur, respectivement 21 et 31, accrochée sur le tube 20, 30, supérieur, et reposant sur les tubes 20, 30, latéraux.The other side of each of sets 2 and 3 is bordered by a plate, or deflector, respectively 21 and 31, hung on the tube 20, 30, upper, and resting on the tubes 20, 30, lateral.

La fixation de la plaque 21, respectivement 31, sur le tube supérieur 20, respectivement 30, est réalisée par l'intermédiaire d'un double pli 22, respectivement 32, sensiblement en forme de U renversé que comporte longitudinalement au niveau de son bord supérieur la plaque 21, respectivement 31, cette disposition permettant la dépose de celle-ci en vue notamment de son nettoyage.The fixing of the plate 21, respectively 31, on the tube upper 20, respectively 30, is achieved by through a double fold 22, respectively 32, substantially in the shape of an inverted U longitudinally at its upper edge, the plate 21, respectively 31, this provision allowing the removal of this in particular for its cleaning.

On notera la présence de barres 23, 33, solidaires des plaques 21 et 31, destinées à s'intercaler entre ces dernières et les tubes 20 et 30, permettant de créer un espace entre les plaques 21 et 31 et les tubes 20 et 30.Note the presence of bars 23, 33, integral with the plates 21 and 31, intended to be inserted between the latter and the tubes 20 and 30, allowing to create a space between the plates 21 and 31 and tubes 20 and 30.

Les plaques 21 et 31 sont donc chacune inclinées dans le sens inverse des parois latérales respectivement 10 et 11, et elles forment avec celles-ci deux hottes disposées de part et d'autre la région médiane de l'avaloir 1, dont les bases s'ouvrent sur le foyer, non représenté.The plates 21 and 31 are therefore each inclined in the direction opposite side walls 10 and 11 respectively, and they form therewith two hoods arranged on either side the middle region of downstream 1, the bases of which open onto the hearth, not shown.

Les plaques 21 et 31 comportent chacune, au niveau de leur bord longitudinal inférieur, un rebord, respectivement 24 et 34, s'étendant horizontalement en direction de la région médiane de l' avaloir 1, permettant le positionnement d' une plaque 4 destinée à fermer l'espace compris entre les deux plaques 21 et 31.The plates 21 and 31 each have, at their edge lower longitudinal, a rim, respectively 24 and 34, extending horizontally towards the middle region of the drain 1, allowing the positioning of a plate 4 intended to close the space between the two plates 21 and 31.

On notera que de préférence la plaque 4 est de forme convexe en direction du foyer. It will be noted that preferably the plate 4 is of convex shape in home management.

On peut également voir sur la figure 1 que la paroi arrière 12 comporte dans sa partie basse une arrivée d'eau 13, et que l'avaloir 1 comporte dans sa partie haute deux tubes 14 et 15, lesquels communiquent avec le réservoir de la paroi avant et traversent la paroi arrière 12 pour se rejoindre sur le circuit de chauffage.We can also see in Figure 1 that the rear wall 12 has in its lower part a water inlet 13, and that the drain 1 has in its upper part two tubes 14 and 15, which communicate with the tank of the front wall and cross the rear wall 12 to join the circuit of heating.

En fonctionnement, l'eau entre dans la paroi arrière 12 par l'arrivée 13 et passe dans la paroi avant par les tubes 20 et 30. Les produits de combustion, dirigés par la plaque 4 vers les ensembles 2 et 3, passent entre les tubes 20 et 30 qui, du fait de leur disposition et du rétrécissement de l'espace, ralentissent les produits de combustion ce qui permet l'échauffant des tubes 20 et 30 et donc de l'eau qui y circule. Puis, l'eau chaude monte dans la paroi avant et s'échappe par les tubes 14 et 15 pour alimenter le circuit de chauffage.In operation, water enters the rear wall 12 through the inlet 13 and passes into the front wall through the tubes 20 and 30. The products of combustion, directed by the plate 4 towards the assemblies 2 and 3, pass between the tubes 20 and 30 which, from the made of their arrangement and shrinking space, slow down the combustion products which allows the heating of tubes 20 and 30 and therefore of the water which there circulates. Then the hot water rises in the front wall and escapes through tubes 14 and 15 to supply the circuit heater.

Le dispositif de chaudière d'âtre selon l'invention autorise une montée plus rapide en température de l'eau, ce qui permet une économie de combustible.The hearth boiler device according to the invention allows a faster rise in water temperature, which allows fuel savings.

Si on se réfère maintenant à la figure 2, on peut voir un échangeur plan 5, destiné à être disposé de manière optionnelle au fond du foyer, non représenté.If we now refer to Figure 2, we can see a planar exchanger 5, intended to be optionally arranged at the back of the hearth, not shown.

L'échangeur 5, réalisé en fonte, est analogue à ceux existants de ce type, il comporte un circuit interne 50 qui le parcourt complètement en passant de la périphérie vers le centre, et connecté à une entrée 51 et une sortie 52 d'eau.The exchanger 5, made of cast iron, is similar to those existing of this type, it has an internal circuit 50 which runs through it completely from the periphery to the center, and connected to an inlet 51 and an outlet 52 for water.

L'entrée d'eau 51 est reliée au retour du circuit de chauffage, tandis que la sortie 52 est connectée à l'entrée 13 de la paroi arrière 12 de l'avaloir 1. The water inlet 51 is connected to the return of the heating circuit, while the outlet 52 is connected to the inlet 13 of the wall rear 12 of the outlet 1.

L'échangeur 5 a pour fonction de préchauffer l'eau avant son passage dans l'avaloir 1, ce qui permet d'atteindre la température désirée plus rapidement.The exchanger 5 has the function of preheating the water before it passage in the outlet 1, which makes it possible to reach the desired temperature faster.
