Description

Domaine techniqueTechnical area

L'invention se rapporte au domaine technique des poêles, notamment des poêles à granulés. Plus précisément, l'invention concerne les poêles de type poêle-cheminée où il est possible d'observer le feu comme dans une cheminée.The invention relates to the technical field of stoves, in particular pellet stoves. More precisely, the invention relates to stoves of the stove-fireplace type where it is possible to observe the fire as in a fireplace.

État de l'artState of the art

Un poêle connu de l'état de la technique, notamment du document FR 3 038 034 , comporte :

  • un module de combustion, renfermant le foyer d'un poêle ;
  • un module d'alimentation, permettant d'alimenter le foyer en combustible solide.
A stove known from the state of the art, in particular from document FR 3,038,034 , comprises:
  • a combustion module, enclosing the hearth of a stove;
  • a power supply module, making it possible to supply the fireplace with solid fuel.

Le module d'alimentation comporte des parois délimitant un espace de stockage de combustible solide (p.3, 1.28-30). Le module de combustion et le module d'alimentation sont des modules séparés, sans être enveloppés d'un habillage commun. En outre, un tel poêle de l'état de la technique comporte un panneau mural de protection dédié, distinct d'une paroi d'habillage, et agencé entre le module de combustion et les parois délimitant l'espace de stockage. Le panneau mural peut être monté sur la paroi avant de l'espace de stockage (p.13, 1.14-15 ; fig.4). Selon une variante, le panneau mural peut former la paroi avant de l'espace de stockage (p.13, 1.10-12; fig.5). Le panneau mural de protection est conçu pour protéger le mur mais également l'espace de stockage, et donc le combustible, de la chaleur rayonnée par le module de combustion via sa face arrière (p.3, 1.20-24).The power supply module has walls delimiting a solid fuel storage space (p.3, 1.28-30). The combustion module and the power supply module are separate modules, without being surrounded by a common covering. In addition, such a stove of the state of the art comprises a dedicated protective wall panel, separate from a covering wall, and arranged between the combustion module and the walls delimiting the storage space. The wall panel can be mounted on the front wall of the storage space (p.13, 1.14-15; fig.4 ). Alternatively, the wall panel can form the front wall of the storage space (p.13, 1.10-12; fig.5 ). The protective wall panel is designed to protect the wall but also the storage space, and therefore the fuel, from the heat radiated by the combustion module via its rear face (p.3, 1.20-24).

Un tel poêle de l'état de la technique n'est pas entièrement satisfaisant dans la mesure où le panneau mural de protection peut s'avérer volumineux et complexifie la conception du poêle, en particulier lorsque le panneau mural forme la paroi avant de l'espace de stockage. L'aspect volumineux du panneau mural de protection peut également alourdir l'esthétisme selon la nature de la pièce à chauffer.Such a state-of-the-art stove is not entirely satisfactory insofar as the protective wall panel can be bulky and complicates the design of the stove, in particular when the wall panel forms the front wall of the stove. storage space. The voluminous appearance of the protective wall panel can also weigh down the aesthetics depending on the nature of the room to be heated.

Le document WO 2016/207395 A1 divulgue un poêle à combustible solide avec une gaine d'alimentation, adaptée pour être installée entre un module d'alimentation en combustible solide et un module de combustion dudit combustible solide. La gaine comprend un conduit d'alimentation pour alimenter le module de combustion en combustible solide, un conduit d'admission d'air pour alimenter le module de combustion en air, et un conduit d'évacuation des fumées pour évacuer vers le module d'alimentation les fumées émises par la combustion. Au moins une partie du conduit d'admission d'air est intercalée entre le conduit d'alimentation et le conduit d'évacuation des fumées.The document WO 2016/207395 A1 discloses a solid fuel stove with a supply duct, adapted to be installed between a solid fuel supply module and a combustion module of said solid fuel. The sheath comprises a supply duct for supplying the combustion module with solid fuel, an air intake duct for supplying the combustion module with air, and a flue gas exhaust duct for evacuating towards the combustion module. feeds the fumes emitted by combustion. At least part of the air intake duct is interposed between the supply duct and the smoke evacuation duct.

Le document EP 1 327 825 A1 décrit un poêle à pellets comprenant une chambre de combustion à pellets, un circuit d'évacuation conduisant à une cheminée pour l'évacuation des fumées et comprenant au moins un section latérale s'étendant vers le bas depuis le sommet de ladite chambre de combustion, un circuit d'admission d'air ambiant s'étendant vers le bas comprenant au moins une entrée d'air, et au moins une section en relation d'échange thermique avec ladite section s'étendant vers le bas dudit circuit d'évacuation pour chauffer l'air ambiant aspiré, et un circuit d'alimentation en air chauffé comprenant au moins un conduit ayant sa sortie au niveau du sol.The document EP 1 327 825 A1 describes a pellet stove comprising a pellet combustion chamber, an evacuation circuit leading to a chimney for the evacuation of fumes and comprising at least one lateral section extending downwards from the top of said combustion chamber, a downwardly extending ambient air intake circuit comprising at least one air inlet, and at least one section in heat exchange relation with said downwardly extending section of said exhaust circuit for heating the aspirated ambient air, and a heated air supply circuit comprising at least one duct having its outlet at ground level.

Exposé de l'inventionDisclosure of the invention

L'invention vise à remédier en tout ou partie aux inconvénients précités. A cet effet, l'invention a pour objet un poêle, comportant :

  • une armature, délimitant un volume de réception ;
  • une enceinte de combustion, agencée en dehors du volume de réception, et comprenant un brûleur alimenté en air comburant pour produire une flamme ;
  • un réservoir à combustible, agencé dans le volume de réception ;
  • des moyens de fixation, agencés pour fixer l'enceinte de combustion à l'armature de manière à laisser une zone d'espacement entre l'enceinte de combustion et l'armature ;
  • un tube d'approvisionnement, comprenant une partie s'étendant dans la zone d'espacement, et agencé pour relier le réservoir à combustible à l'enceinte de combustion de manière à approvisionner le brûleur en combustible ;
  • un conduit d'évacuation, agencé dans le volume de réception pour évacuer des fumées de combustion hors de l'armature ;
  • un tube d'évacuation, comprenant une partie s'étendant dans la zone d'espacement, et agencé pour relier l'enceinte de combustion au conduit d'évacuation de manière à évacuer les fumées de combustion de l'enceinte de combustion ;
  • un échangeur thermique, agencé dans le volume de réception pour transférer l'énergie thermique des fumées de combustion à un air ambiant d'une première pièce à chauffer circulant dans le volume de réception, l'échangeur thermique comprenant une plaque de séparation agencée pour délimiter des première et seconde surfaces de transfert ;
  • des premiers moyens de circulation, agencés pour faire circuler l'air ambiant de la première pièce à chauffer dans le volume de réception via la première surface de transfert de l'échangeur thermique, les premiers moyens de circulation étant destinés à expulser l'air ambiant chauffé par la première surface de transfert vers la première pièce à chauffer ;
  • des deuxièmes moyens de circulation, agencés pour faire circuler l'air ambiant de la première pièce à chauffer dans le volume de réception via la seconde surface de transfert de l'échangeur thermique, les deuxièmes moyens de circulation étant destinés à expulser l'air ambiant chauffé par la seconde surface de transfert vers une deuxième pièce à chauffer.
The invention aims to remedy all or part of the aforementioned drawbacks. To this end, the invention relates to a stove, comprising:
  • a frame, delimiting a reception volume;
  • a combustion chamber, arranged outside the receiving volume, and comprising a burner supplied with combustion air to produce a flame;
  • a fuel tank, arranged in the receiving volume;
  • fixing means, arranged to fix the combustion chamber to the frame so as to leave a space between the combustion chamber and the frame;
  • a supply tube, comprising a portion extending into the spacing zone, and arranged to connect the fuel tank to the combustion chamber so as to supply the burner with fuel;
  • an evacuation duct, arranged in the receiving volume to evacuate combustion fumes from the frame;
  • an exhaust tube, comprising a portion extending into the spacing zone, and arranged to connect the combustion chamber to the exhaust duct so as to discharge the combustion fumes from the combustion chamber;
  • a heat exchanger, arranged in the reception volume to transfer the thermal energy of the combustion fumes to an ambient air of a first room to be heated circulating in the reception volume, the heat exchanger comprising a separation plate arranged to delimit first and second transfer surfaces;
  • first circulation means, arranged to circulate the ambient air of the first room to be heated in the receiving volume via the first transfer surface of the heat exchanger, the first circulation means being intended to expel the ambient air heated by the first transfer surface to the first part to be heated;
  • second circulation means, arranged to circulate the ambient air of the first room to be heated in the receiving volume via the second transfer surface of the heat exchanger, the second circulation means being intended to expel the ambient air heated by the second transfer surface to a second part to be heated.

Ainsi, un tel poêle selon l'invention permet de s'affranchir d'un panneau mural de protection dédié en réduisant le flux de rayonnement thermique transmis par la face arrière (i.e. orientée vers la zone d'espacement) de l'enceinte de combustion. Ceci est rendu possible grâce :

  • au tube d'évacuation qui permet d'évacuer les fumées de combustion hors de l'enceinte de combustion ;
  • à l'échangeur thermique, agencé dans le volume de réception délimité par l'armature, et permettant le transfert de l'énergie thermique des fumées de combustion dans le volume de réception, et non dans l'enceinte de combustion ;
  • aux premiers et deuxièmes moyens de circulation, qui permettent une diffusion de la chaleur par convection.
Thus, such a stove according to the invention makes it possible to dispense with a dedicated protective wall panel by reducing the flow of thermal radiation transmitted by the rear face (ie oriented towards the spacing zone) of the combustion chamber. . This is made possible by:
  • the evacuation tube which allows the combustion fumes to be evacuated from the combustion chamber;
  • the heat exchanger, arranged in the receiving volume delimited by the frame, and allowing the transfer of thermal energy from the combustion fumes in the receiving volume, and not in the combustion chamber;
  • the first and second circulation means, which allow heat to be diffused by convection.

Il est donc rendu possible de monter de simples parois d'habillage sur l'armature et éventuellement de prévoir une couche d'isolation thermique ou une lame d'air agencée autour du réservoir à combustible et/ou de prévoir des matériaux de type isolants thermiques agencés de part et d'autre de la face arrière de l'enceinte de combustion, ce qui est moins encombrant et plus simple à mettre en œuvre qu'un panneau mural de protection, pour limiter la température et réduire le rayonnement du foyer, à l'arrière de l'enceinte de combustion.It is therefore made possible to mount simple covering walls on the frame and possibly to provide a thermal insulation layer or an air space arranged around the fuel tank and / or to provide materials of the thermal insulating type. arranged on either side of the rear face of the combustion chamber, which is less bulky and easier to implement than a protective wall panel, to limit the temperature and reduce the radiation of the fireplace, at the rear of the combustion chamber.

En outre, le réservoir à combustible comporte ses propres parois, distinctes des parois d'habillage de l'armature qui peuvent par exemple être montées sur l'armature lors de l'installation du poêle dans une pièce à chauffer (in situ), ou être montées sur l'armature en usine, avant l'installation du poêle sur site. Ainsi, un tel poêle selon l'invention permet également de s'affranchir d'un panneau mural de protection formant une paroi du réservoir à combustible, ce qui simplifie la conception du poêle.In addition, the fuel tank has its own walls, separate from the cladding walls of the frame which can for example be mounted on the frame when installing the stove in a room to be heated ( in situ ) , or be fitted to the frame at the factory, before the stove is installed on site. Thus, such a stove according to the invention also makes it possible to dispense with a protective wall panel forming a wall of the fuel tank, which simplifies the design of the stove.
