Description

L'invention concerne un système de chauffage dit mixte, hybride ou encore à double combustion, c'est-à-dire pouvant fonctionner avec deux types d'énergie, par exemple avec des bûches de bois et/ou avec des granulés de bois ou pellets.The invention relates to a so-called mixed heating system, hybrid or dual combustion, that is to say able to operate with two types of energy, for example with logs of wood and / or with wood pellets or pellets.

On connaît déjà des poêles à bois à double combustion capables de fonctionner avec des buches de bois ou avec des granulés de bois. Un tel poêle est par exemple décrit dans le document de brevet W02009/115 969 . Dans ce poêle à bois connu, il y a une première chambre de combustion ou foyer pour les buches de bois et une seconde chambre de combustion ou foyer pour les granulés de bois. Ces deux chambres de combustion sont séparées l'une de l'autre mais la chambre de combustion pour les granulés de bois est montée mobile par rapport à la chambre de combustion pour les buches de bois de façon à pouvoir s'encastrer dans celle-ci et dans ce cas le poêle peut fonctionner avec des granulés de bois ou où au contraire pour pouvoir être sortie de celle-ci et dans ce cas le poêle peut fonctionner avec des buches de bois.There are already known dual burning wood stoves capable of working with wood logs or with wood pellets. Such a stove is for example described in the patent document W02009 / 115 969 . In this known wood stove, there is a first combustion chamber or firebox for wood logs and a second firebox or firebox for wood pellets. These two combustion chambers are separated from each other but the combustion chamber for the wood pellets is mounted movably relative to the combustion chamber for the wood logs so as to fit into it and in this case the stove can work with wood pellets or where on the contrary to be able to be out of it and in this case the stove can work with wood logs.

On connait par ailleurs le document de brevet EP 0 930 473 qui décrit un chauffe-eau au gaz naturel comportant des tuyaux de transport de l'eau réchauffée par des brûleurs principaux à gaz. Pour pallier à l'inesthétique des systèmes existants similaires, ce chauffe eau comporte un foyer délimité par des pièces moulées en verre ou céramique. De manière complémentaire, ce chauffe-eau peut également comporter un foyer pour réchauffer de l'air et servir de chauffage d'appoint de la pièce dans laquelle il est installé. Dans cette configuration, le brûleur d'appoint est séparé des brûleurs principaux par une paroi. Cette paroi est réalisée en tôle et sert à guider les fumées. Le brûleur d'appoint est prévu derrière une vitre transparente le rendant visible de l'extérieure et doublée d'une seconde paroi en verre faisant office d'isolation thermique et limitant les risques de brûlures contre la face avant du chauffe eau. Cette vitre permet de conférer l'aspect visuel d'une cheminée au chauffe-eau.We also know the patent document EP 0 930 473 which describes a natural gas water heater having pipes for conveying water heated by main gas burners. To overcome the unsightly similar existing systems, this water heater has a focus delimited by molded pieces of glass or ceramic. In addition, this water heater may also include a fireplace to heat the air and serve as additional heating of the room in which it is installed. In this configuration, the backup burner is separated from the main burners by a wall. This wall is made of sheet metal and serves to guide the fumes. The backup burner is provided behind a transparent window making it visible from the outside and lined with a second glass wall acting as thermal insulation and limiting the risk of burns against the front face of the water heater. This window makes it possible to confer the visual appearance of a chimney to the water heater.

On connait également le document de brevet WO 2010/033 797 qui décrit un système de chauffage à foyer fermé comportant notamment une résistance électrique utilisée pour le démarrage de la combustion, cette résistance électrique étant prévue dans l'enceinte du système de chauffage à foyer fermé.We also know the patent document WO 2010/033 797 which describes a closed hearth heating system including an electrical resistance used for the start of combustion, the electrical resistance being provided in the enclosure of the closed fire heating system.

On connait également le document de brevet WO 2008/059 300 qui décrit un système de chauffage à foyer fermé comportant un foyer alimenté en air par trois circuits distincts, un premier circuit débouchant sous les barres portantes du foyer, un second longeant la face interne de la vitre du foyer fermé et un troisième circuit débouchant par l'arrière du foyer.We also know the patent document WO 2008/059 300 which describes a closed hearth heating system comprising a furnace supplied with air by three separate circuits, a first circuit opening under the load-bearing bars of the hearth, a second running along the internal face of the closed hearth pane and a third circuit opening through the back of the fireplace.

On connait également le document de brevet EP 1 327 825 qui décrit un système de chauffage à foyer fermé comportant notamment un ventilateur couplé à un moteur électrique, le ventilateur étant prévu pour faire circuler de l'air dans un conduit débouchant par une prise d'air frais prévue sur la face avant du système de chauffage, au-dessus de la vitre protégeant le foyer. Le conduit débouchant passe à l'arrière du foyer pour autoriser le chauffage de l'air, et il est raccordé à des conduits de distribution d'air chauffé.We also know the patent document EP 1 327 825 which describes a closed hearth heating system comprising in particular a fan coupled to an electric motor, the fan being designed to circulate air in a duct opening by a fresh air intake provided on the front face of the heating system , above the window protecting the fireplace. The opening duct passes to the back of the fireplace to allow the heating of the air, and it is connected to heated air distribution ducts.

On connait également le document de brevet US 5,137,012 qui décrit un système de chauffage à foyer fermé pourvu de conduits d'air frais débouchant en partie supérieure à l'arrière de la vitre protégeant le foyer de manière à provoquer un déplacement d'air léchant la paroi intérieure de la vitre pour limiter son encrassement. La vitre est ainsi autonettoyante.We also know the patent document US 5,137,012 which describes a closed hearth heating system provided with fresh air ducts opening at the top of the rear of the window protecting the fireplace so as to cause a displacement of air licking the inner wall of the window to limit its fouling . The glass is self-cleaning.

On connait également le document de brevet DE 10 2005 049 276 qui décrit un système de chauffage comportant une chambre de combustion unique. Cette chambre de combustion peut être utilisée pour brûler des bûches de bois ou des granulés de bois, transférés dans la chambre de combustion par une plaque prévue à l'arrière de la chambre de combustion et mobile en translation verticale.We also know the patent document DE 10 2005 049 276 which describes a heating system having a single combustion chamber. This combustion chamber can be used to burn wood logs or wood pellets, transferred into the combustion chamber by a plate provided at the rear of the combustion chamber and movable in vertical translation.

On connait enfin le document de brevet WO 2004/046 614 qui décrit un système de chauffage apte à fonctionner avec des bûches de bois et des granulés de bois.We finally know the patent document WO 2004/046 614 which describes a heating system that can work with logs and wood pellets.

Le but de l'invention est de proposer un système de chauffage à double combustion, en particulier un poêle à bois à usage domestique pour le chauffage d'une habitation, apte à fonctionner en même temps ou séparément avec par exemple des buches de bois et/ou des granulés de bois.The object of the invention is to provide a dual combustion heating system, in particular a wood stove for domestic use for heating a dwelling, able to operate simultaneously or separately with for example wood logs and / or wood pellets.

Un autre but de l'invention est de proposer un tel système de chauffage à double combustion qui présente une réelle ergonomie pour être disposé dans une pièce de vie d'une habitation tout en offrant un rendement satisfaisant.Another object of the invention is to provide such a dual combustion heating system which has real ergonomics to be arranged in a living room of a home while providing satisfactory performance.

Sur la figure 1, on a représenté de façon très schématique un système de chauffage à bois hybride ou mixte 1 à double foyers selon l'invention qui peut fonctionner selon trois modes de fonctionnement, à savoir alternativement avec des bûches de bois ou avec des granulés de bois ou pellets, ou simultanément avec des bûches de bois et des pellets.On the figure 1 , a schematic representation of a system hybrid wood heating system or mixed dual fireplaces according to the invention which can operate in three modes of operation, namely alternately with logs of wood or with wood pellets or pellets, or simultaneously with logs of wood and wood. pellets.

Le système de chauffage à bois illustré sur la figure 1 selon l'invention est ici un poêle à bois destiné à équiper une pièce à vivre dans une habitation ou encore un bureau.The wood heating system shown on the figure 1 according to the invention is here a wood stove to equip a living room in a home or office.

Ce poêle à bois 1 est dans l'exemple en forme de colonne ici à section transversale hexagonale. La hauteur de ce poêle à bois peut être par exemple de 120mm et sa section de l'ordre de 600mm.This wood stove 1 is in the example in column form here hexagonal cross section. The height of this wood stove can be for example 120mm and its section of the order of 600mm.

La structure générale du poêle à bois 1 (visible aussi sur les figures 3 et 4) est constituée principalement de trois blocs superposés, ayant des hauteurs sensiblement égales, à savoir : a) un bloc inférieur 2 formant un socle et dans lequel peuvent être disposés un ventilateur 3 d'air chaud et de combustion pour le foyer à pellets, un compartiment 4 pour ranger des bûches de bois et un tiroir à cendres 5 pour le foyer à bûches de bois; b) un bloc intermédiaire 6 dans lequel sont disposés en juxtaposition les deux foyers 7 et 8 respectivement à bûches de bois et à pellets sur un même plan horizontal, et enfin c) un bloc supérieur 9 dans lequel peuvent être disposées une boîte à fumée 10, une trémie 11 et une vis sans fin motorisée 12 pour les pellets ainsi qu'une électronique de commande et de réglage du système de chauffage à pellets. L'électronique peut comprendre un pupitre de commande fixé au revers d'une trappe d'accès 13 à la trémie 11 disposée sur le dessus du poêle.The general structure of the wood stove 1 (also visible on the Figures 3 and 4 ) consists mainly of three superimposed blocks, having substantially equal heights, namely: a) a lower block 2 forming a base and in which can be arranged a fan 3 of hot air and combustion for the pellet fireplace, a compartment 4 for storing wood logs and an ash drawer 5 for the log burner; b) an intermediate block 6 in which are arranged in juxtaposition the two fireplaces 7 and 8 respectively with logs of wood and pellets on the same horizontal plane, and finally c) an upper block 9 in which can be arranged a smoke box 10 , a hopper 11 and a motorized auger 12 for pellets and an electronic control and adjustment of the pellet heating system. The electronics may include a control panel attached to the back of an access hatch 13 to the hopper 11 disposed on the top of the stove.

Comme visible sur les figures 1, 3 et 4, l'évacuation des fumées se fait ici par le dessus du poêle mais il est entendu qu'elle pourrait aussi se faire par l'arrière du poêle sans sortir du cadre de l'invention.As visible on Figures 1, 3 and 4 , the evacuation of smoke is done here from above the stove but it is understood that it could also be done from the back of the stove without departing from the scope of the invention.

Un élément de raccordement 14 à un conduit de fumée à double flux est fixé de façon étanche sur le dessus de la boite à fumée 10 et donc sur le dessus du poêle. Cet élément de raccordement monobloc comprend aussi un piquage (ici oblique) pour un conduit flexible de prise d'air frais récupéré à travers un des deux canaux du conduit de fumée à double flux.A connection element 14 to a double flow smoke duct is sealed to the top of the smoke box 10 and thus on the top of the stove. This one-piece connection element also comprises a stitching (here oblique) for a flexible intake fresh air duct recovered through one of the two channels of the double-flow smoke duct.

La disposition de cet élément de raccordement 14 monobloc permet un tirage naturel du foyer à bûches de bois et un rendement amélioré du foyer à pellets grâce à une réduction des pertes de charges. En outre, la réalisation monobloc de l'élément de raccordement 14 contribue à une économie de composants et un gain de temps au montage.The provision of this monobloc connection element 14 allows a natural draft of the wood fire and improved performance of the pellet fireplace through a reduction of pressure losses. In addition, the one-piece construction of the connecting element 14 contributes to a saving of components and a time saving during assembly.

Sur les figures 1 et 4, on voit que le conduit d'air frais 16 est un flexible qui part du piquage 15 et qui descend sous le foyer à pellets, le flux d'air frais étant représenté par des flèches blanches. Les fumées produites par le foyer à pellets sont évacués de façon naturelle (voir les flèches sombres sur les figures 3 et 4) à la verticale à travers la boîte à fumée 10. Le foyer à bûches de bois est quant à lui indépendant du ventilateur 3, l'entrée d'air frais se faisant à travers le tiroir à cendres 5. Les fumées du foyer à bûches de bois s'évacuent par la boite à fumée 10 à travers une canalisation munie d'une trappe anti-retour 17 de fumée.On the Figures 1 and 4 it can be seen that the fresh air duct 16 is a hose which starts from the tap 15 and which goes down under the pellet stove, the fresh air flow being represented by white arrows. The fumes produced by the pellet stove are evacuated in a natural way (see the dark arrows on the Figures 3 and 4 The log firebox is independent of the fan 3, the fresh air inlet being through the ash drawer 5. The fumes from the log fire of wood are evacuated through the smoke box 10 through a pipe provided with a non-return smoke door 17.

Par ailleurs, il est prévu dans l'agencement de ce poêle, une circulation d'air qui est prélevé dans la pièce depuis le bloc intermédiaire 6 à travers des ouvertures 18, qui est ensuite réchauffé dans ce bloc intermédiaire 18 par l'un ou les deux foyers et qui est renvoyé dans la pièce par le bas du bloc inférieur 2.Furthermore, there is provided in the arrangement of this stove, a circulation of air which is drawn into the room from the intermediate block 6 through openings 18, which is then reheated in this intermediate block 18 by one or both homes and returned to the room from the bottom of the lower block 2.

Selon l'invention, les deux foyers 7 et 8 sont séparés par une paroi vitrée 19 commune visible sur la figure 2 et le foyer 7 à bûches de bois (référencées par 20) est muni d'une porte vitrée 21 en façade du poêle disposée de telle sorte que la paroi vitrée 19 se présente en arrière plan de la porte vitrée 21 dans le foyer 7. Le foyer à bûches de bois 7 joue en quelque sorte le rôle d'un sas intermédiaire pour le foyer à pellets 8. Comme on peut le comprendre, le foyer à pellets 8 n'a pas d'ouverture en façade vers l'extérieur du poêle et le doublage de la paroi vitrée 19 par la porte vitrée 21 contribue à l'obtention d'un très bon rendement du système de chauffage à pellets comparable à celui d'une chaudière à pellets.According to the invention, the two foci 7 and 8 are separated by a common glass wall 19 visible on the figure 2 and fireplace 7 wood logs (referenced 20) is provided with a glass door 21 in front of the stove arranged so that the glass wall 19 is in the background of the glass door 21 in the fireplace 7. The wood log fireplace 7 acts as a sort of intermediate lock for the 8 pellet fireplace. it can be understood, the fireplace pellet 8 has no opening in front of the stove and the doubling of the glass wall 19 by the glass door 21 contributes to obtaining a very good performance of the pellet heating system comparable to that of a pellet boiler.

La porte vitrée 21 est également arrondie ou bombée vers l'extérieur du poêle et la paroi vitrée 19 présente aussi une forme arrondie ou bombée (ici en forme d'arc de cercle) vers l'intérieur du foyer 7 ce qui procure une vision panoramique, depuis l'extérieur du poêle, de la flamme sortant du creuset 22 du foyer à pellets 8. On peut concevoir un double vitrage pour la porte 21 comme pour la paroi 19 sans sortir du cadre de l'invention. Sur la figure 2, les parties rectilignes de la paroi 19 de séparation entre les deux foyers 7 et 8 peuvent être en fonte ou encore en tôle. Les parois non vitrées des foyers 7 et 8 (en particulier les parois en façade du poêle) peuvent avantageusement être couvertes par un élément solide d'accumulation et de diffusion lente de chaleur tel que 23 du type en céramique ou stéatite. Le même élément d'accumulation peut également couvrir les parois extérieures de la boîte à fumée 10. La partie vitrée de la paroi 19 peut être montée sur un châssis basculant ou rotatif permettant un accès à la surface de cette paroi située du côté du foyer 8, par exemple pour permettre son nettoyage.The glass door 21 is also rounded or curved toward the outside of the stove and the glass wall 19 also has a rounded or curved shape (here in the shape of a circular arc) towards the interior of the fireplace 7 which provides a panoramic view from the outside of the stove, the flame leaving the crucible 22 of the pellet burner 8. Can be designed double glazing for the door 21 as for the wall 19 without departing from the scope of the invention. On the figure 2 , the rectilinear portions of the partition wall 19 between the two foci 7 and 8 may be cast iron or still sheet. The unglazed walls of the fireplaces 7 and 8 (in particular the walls at the front of the stove) can advantageously be covered by a solid element of accumulation and slow diffusion of heat such as 23 of the ceramic or steatite type. The same accumulation element can also cover the outer walls of the smoke box 10. The glass part of the wall 19 can be mounted on a tilting or rotary frame allowing access to the surface of this wall located on the side of the fireplace 8 for example to allow cleaning.

Le foyer à bûches de bois 7 peut donc diffuser directement de la chaleur dans la pièce à travers la porte vitrée 21. La chaleur fournie par le foyer à pellets 8 est stockée dans l'accumulateur 23 pour être diffusée lentement en façade et sur le dessus du poêle.The log burner 7 can therefore diffuse heat directly into the room through the glass door 21. The heat supplied by the pellet burner 8 is stored in the accumulator 23 to be diffused slowly in front and on the top stove.

Selon l'invention, une résistance électrique de chauffage (non représentée) peut être intégrée dans l'élément solide d'accumulation et de diffusion lente de chaleur 23 pour constituer par exemple un système de chauffage d'appoint ou de mise hors gel quand les deux foyers 7 et 8 ne sont pas utilisés. Le fonctionnement de ce système de chauffage d'appoint peut être commandé depuis le pupitre de commande ou à distance avec des moyens de télécommunication.According to the invention, an electrical heating resistor (not shown) can be integrated in the solid storage and slow heat diffusion element 23 to form, for example, an auxiliary heating or frost protection system when the two fireplaces 7 and 8 are not used. The operation of this auxiliary heating system can be controlled from the control panel or remotely with telecommunication means.

Sur les figures 5 à 7, on a illustré l'effet de vision panoramique procuré par la porte vitrée 21 doublant la paroi vitrée 19 et ce pour différentes formes de section de la colonne du poêle.On the Figures 5 to 7 , the panoramic vision effect provided by the glass door 21 doubling the glass wall 19 and this for different shapes of section of the stove column.

Sur la figure 5, le poêle a une section transversale hexagonale et la porte vitrée 21 est pliée sur trois pans et offre un champ de vision d'environ 180° sur le foyer à bûches de bois 7 et d'environ 132° sur le foyer à pellets.On the figure 5 , the stove has a hexagonal cross-section and the glass door 21 is folded on three sides and has a field of view of about 180 ° on the log fire 7 and about 132 ° on the pellet fireplace.

Sur la figure 6, le poêle à une section transversale rectangulaire et ici carrée et la porte vitrée 21 et pliée sur deux pans et offre un champ de vision d'environ 162° sur le foyer à bûches de bois et d'environ 108° sur le foyer à pellets.On the figure 6 , the stove has a rectangular cross section and square here and the glass door 21 and folded on two sides and offers a field of view of about 162 ° on the log fire and about 108 ° on the fireplace pellet .

Sur la figure 7, le poêle à une section transversale circulaire et la porte vitrée 21 est cintrée et offre un champ de vision d'environ 219° sur le foyer à bûches de bois et d'environ 180° sur le foyer à pellets.On the figure 7 , the stove has a circular cross section and the glass door 21 is curved and has a field of view of about 219 ° on the wood fire and about 180 ° on the fireplace.

La construction du poêle selon l'invention permet donc d'obtenir une vision panoramique des flammes des deux foyers en même temps ou de façon séparée. Cette construction contribue en outre à l'obtention d'un meilleur rendement que les poêles mixtes classiques. Elle élimine par ailleurs la présence d'une porte vitrée sur le foyer à pellets laquelle peut constituer un risque d'accident par brûlure pour les enfants par exemple.The construction of the stove according to the invention thus provides a panoramic view of the flames of the two homes at the same time or separately. This construction also contributes to obtaining a better performance than conventional mixed stoves. It also eliminates the presence of a glass door on the fireplace pellet which can be a risk of burn accident for children for example.

La porte vitrée (qui peut être tournante ou coulissante ou encore basculante) peut être avantageusement protégée par une barrière de sécurité éventuellement rétractable comme cela est bien connu. La paroi vitrée comme la porte vitrée peuvent être conçues autonettoyantes par exemple grâce à un dépôt de dioxyde de titane.The glass door (which can be rotating or sliding or tilting) can be advantageously protected by a possibly retractable security barrier as is well known. The glass wall as the glass door can be designed self-cleaning for example through a deposit of titanium dioxide.

Le poêle selon l'invention peut être conçu comme indiqué plus haut pour que de l'air ambiant prélevé sensiblement à mi-hauteur de la colonne du poêle par les ouvertures 18 soit refoulé au niveau de la partie la plus basse du poêle au ras du sol. Plus particulièrement, le ventilateur 3 par exemple peut être raccordé à un conduit de circulation d'air 24 qui s'étend entre les entrées d'air 18 et des sorties d'air telles que 25 sur la figure 3. L'entrée d'air 18 du conduit 24 est disposée sensiblement au voisinage du haut de la partie intermédiaire 6 du poêle, soit à environ un mètre du sol, et les sorties d'air 25 sont disposées sensiblement au voisinage du bas de la partie inférieure 2 du poêle, c'est-à-dire pratiquement au ras du sol. Comme visible sur la figure 3, le conduit d'air 24 peut longer l'accumulateur solide 23 pour être en outre réchauffé par conduction ou rayonnement. L'air ambiant qui est aspiré par le ventilateur 3 au niveau des entrées 18 est en général plus chaud que l'air ambiant qui se trouve au ras du sol et ce système de ventilation permet donc un brassage de l'air ambiant pour améliorer le confort dans la pièce où est situé le poêle.The stove according to the invention may be designed as indicated above so that ambient air taken substantially at mid-height of the column of the stove by the openings 18 is discharged at the lowest part of the stove at ground level. More particularly, the fan 3 for example can be connected to an air duct 24 which extends between the air inlets 18 and air outlets such as 25 on the floor. figure 3 . The air inlet 18 of the duct 24 is disposed substantially near the top of the intermediate portion 6 of the stove, ie about one meter from the ground, and the air outlets 25 are arranged substantially near the bottom of the part. lower 2 of the stove, that is to say practically flush with the ground. As visible on the figure 3 , the air duct 24 may follow the solid accumulator 23 to be further heated by conduction or radiation. The ambient air that is sucked by the fan 3 at the inputs 18 is generally warmer than the ambient air which is flush with the ground and this ventilation system therefore allows a mixing of the ambient air to improve the air flow. comfort in the room where the stove is located.
