Description

La présente invention se réfère au fonctionnement d'un appareil de chauffage à bois encastrable, pouvant fonctionner à foyer ouvert ou fermé sur des conduits de fumée dont la section est égale ou supérieure à 200 cm2, cette qualité est intéressante en ce qu'elle permet le branchement des dits appareils sur les conduits collectifs à raccordement individuel « Type Shunt » que l'on trouve fréquemment dans les immeubles collectifs ; dans ce cas il est nécessaire d'accéder facilement au conduit pour effectuer les opérations du ramonage, il faut pouvoir déplacer facilement l'appareil d'où l'invention spécialement conçue pour être encastrée. En effet, l'appareil se présente sous la forme d'un boîtier sans superstructure, ce qui permet de la glisser dans divers aménagements décoratifs sans qu'il y ait démontage des éléments encastrants, par ailleurs un cadre décoratif légèrement surdimensionné par rapport au caisson forme couvre-joint assurant la liaison avec ces éléments.The present invention relates to the operation of a built-in wood-burning appliance, capable of operating with an open or closed hearth on flues with a section equal to or greater than 200 cm 2 , this quality is advantageous in that it allows the connection of said devices to collective conduits with individual “Type Shunt” connection that are frequently found in collective buildings; in this case it is necessary to easily access the duct to carry out the sweeping operations, it must be able to easily move the device from where the invention specially designed to be embedded. Indeed, the device is in the form of a box without superstructure, which allows it to slide into various decorative arrangements without disassembly of the embedding elements, moreover a decorative frame slightly oversized relative to the box joint cover form ensuring the connection with these elements.

Afin d'assurer à l'invention son caractère encastrable, l'évacuation des gaz s'effectue sur la face arrière de l'appareil, aussi pour garantir son bon fonctionnement sans refoulement des fumées à l'intérieur du foyer, il a été conçu un volume situé en avant du manchon d'évacuation des fumées appelé « cage à dépression ». Celle-ci est formée par le positionnement particulier de la plaque déflecteur de flammes, qui est disposée à la base de l'orifice d'évacuation des fumées et qui rejoint le haut du caisson suivant un angle fermé laissant subsister un espace d'admission ; on obtient ainsi un volume dépressionnaire dont l'effet est accentué lors du fonctionnement par la température élevée communiquée à la plaque déflecteur de flammes. L'avantage acquit par la dite cage à dépression est qu'elle accroît le débit d'évacuation des fumées situées dans la partie visible du foyer allant jusqu'à permettre lorsque l'appareil est chaud le fonctionnement à foyer ouvert (portes ouvertes), sans que pour cela la vitesse de combustion soit augmentée, en effet le passage d'air ménagé autour des portes en matériaux transparent qui repousse le flux des fumées à l'arrière de l'appareil contribue à rééquilibrer la pression à l'intérieur du foyer. L'air de combustion proprement dit est distribué sous la grille foyère par l'intermédiaire du tiroir cendrier et est réglable par une porte coulissante située en partie basse de l'appareil.In order to ensure that the invention is built-in, the gases are evacuated on the rear face of the appliance, also to guarantee its proper functioning without the discharge of smoke inside the fireplace, it has been designed a volume located in front of the smoke evacuation sleeve called a “vacuum cage”. This is formed by the particular positioning of the flame deflector plate, which is arranged at the base of the smoke evacuation orifice and which joins the top of the box at a closed angle leaving an intake space; a low pressure volume is thus obtained, the effect of which is accentuated during operation by the high temperature communicated to the flame deflector plate. The advantage acquired by the said vacuum cage is that it increases the evacuation rate of the fumes located in the visible part of the fireplace, going so far as to allow, when the appliance is hot, operation with an open hearth (doors open), without the combustion speed being increased for this, in fact the passage of air formed around the doors made of transparent materials which repels the flow of smoke at the rear of the appliance contributes to rebalancing the pressure inside the hearth . The combustion air proper is distributed under the hearth grate via the ashtray drawer and is adjustable by a sliding door located in the lower part of the appliance.

Ainsi, le dit appareil a l'avantage par rapport aux appareils existant sur le marché généralement équipés d'évacuations verticales nécessitant la construction de « hotte rendant l'appareil inamovible sans démontage des éléments encastrants, d'être facilement déplaçable pour les opérations de ramonage, il offre également l'avantage d'une bonne visibilité de la flamme sans accumulation de fumée à l'intérieur du foyer ce qui est particulièrement intéressant dans le cas des appareils à foyer apparent.Thus, said device has the advantage compared to existing devices on the market generally equipped with vertical outlets requiring the construction of "hood making the device irremovable without dismantling the built-in elements, to be easily movable for sweeping operations , it also offers the advantage of good visibility of the flame without accumulation of smoke inside the hearth which is particularly advantageous in the case of appliances with an apparent hearth.

L'état de la technique antérieure hors mis le fait que les appareils sont inamovibles sans démontage des structures d'habillage, laisse apparaître que leur fonctionnement ne prévoit pas un extracteur de fumée par la constitution d'une cage à dépression, située en avant de l'orifice d'évacuation qui permet d'obtenir un foyer clair et non encombré de fumée. En effet, les brevets US-A-4 230 092, US-A-4 095 581, WO-A-80/01409, décrivent des appareils à évacuation verticale dont le fonctionnement est conditionné par un système de distribution d'air de combustion contrôlée laissant supposer une dépression à l'intérieur du foyer et non pas un volume intermédiaire comme décrit dans l'invention permettant l'extraction des fumées sans influencer la combustion. En outre, le brevet US-A-2703567, décrit un appareil muni d'un déflecteur de chaleur favorisant un passage d'air frais en partie haute de l'appareil qui a pour but de freiner un tirage excessif tout en ménageant une bonne évacuation des fumées, toutefois ce procédé n'a rien de comparable à la constitution d'un volume formant cage à dépression.

  • La figure 2 représente le positionnement de la plaque déflecteur par rapport au conduit d'évacuation des fumées laissant apparaître le rétrécissement en son extrémité avec le haut du caisson par où sont aspirées les fumées dans l'espace dénommé « cage à dépression •.
  • La figure 3 représente une vue latérale de l'appareil où sont représentées les portes en matériaux transparents avec les passages d'air ménagés à leur pourtour, ainsi que le tiroir cendrier positionné sous la grille foyère.
  • La figure 4 représente la circulation d'air destinée à la récupération de chaleur ainsi que l'espace de sortie d'air chaud ménagé sous le cadre décoratif formant couvre-joint avec les éléments encastrants. Elle matérialise également le positionnement des parements en briques réfractaires...
  • La figure 5 schématise les charnières de fixation à pression des portes en matériaux transparent.
The state of the prior art apart from the fact that the devices are irremovable without dismantling the covering structures, suggests that their operation does not provide for a smoke extractor by the constitution of a vacuum cage, located in front of the exhaust opening which provides a clear, unencumbered fireplace. In fact, the patents US-A-4,230,092, US-A-4,095,581, WO-A-80/01409, describe devices with vertical evacuation whose operation is conditioned by a combustion air distribution system controlled suggesting a depression inside the hearth and not an intermediate volume as described in the invention allowing the extraction of fumes without influencing combustion. In addition, patent US-A-2703567 describes an apparatus provided with a heat deflector promoting a passage of fresh air in the upper part of the apparatus which has the purpose of slowing down an excessive draft while providing good evacuation fumes, however this process has nothing comparable to the constitution of a volume forming a vacuum cage.
  • Figure 1 shows a general view of the device open on two sides.
  • FIG. 2 represents the positioning of the deflector plate with respect to the smoke evacuation duct revealing the narrowing at its end with the top of the box through which the fumes are sucked into the space called "vacuum cage".
  • Figure 3 shows a side view of the device where the doors are shown in transparent materials with the air passages provided at their periphery, as well as the ashtray drawer positioned under the hearth grate.
  • FIG. 4 shows the air circulation intended for heat recovery as well as the hot air outlet space formed under the decorative frame forming a joint cover with the embedding elements. It also materializes the positioning of refractory brick facing ...
  • Figure 5 shows schematically the pressure hinges for doors made of transparent materials.

Une double cloison (8), munie de chicanes (9) ayant pour effet d'augmenter la surface des échanges thermiques, est destinée à récupérer la chaleur emmagasinée par le revêtement en briques réfractaires (7), l'air de convection est introduit dans l'appareil par un boîtier réglable situé en bas de l'appareil (II) et ressort sous le cadre décoratif (19) en partie haute de l'appareil qui forme couvre joint et dévoye le flux d'air chaud vers le bas (12). La plaque (2) formant avaloir présente un angle de 20° avec les portes en matériaux transparents (13) autour desquelles est ménagé un espace (20) destiné à créer un courant d'air refoulant le flux des fumées à l'arrière de l'appareil protégeant ainsi les portes en matériaux transparent des dépôts de goudron tout en oxygénant le foyer en partie centrale. Les portes en matériaux transparents sont fixées par des charnières à pression (14) ne nécessitant ni perforation ni cadre métallique susceptible de réduire l'espace visible du foyer. Dans sa partie basse l'appareil est constitué d'un socle (15) muni d'une grille à bûche (16) et d'un cendrier (17) ainsi que d'une porte coulissante (18) servant au réglage du tirage.A double partition (8), provided with baffles (9) having the effect of increasing the surface of the heat exchanges, is intended to recover the heat stored by the lining of refractory bricks (7), the convection air is introduced into the device by an adjustable box located at the bottom of the device (II) and comes out under the frame decorative (19) in the upper part of the device which forms a joint cover and directs the flow of hot air downwards (12). The plate (2) forming a drain has an angle of 20 ° with the doors of transparent materials (13) around which is formed a space (20) intended to create a current of air driving the flow of smoke at the rear of the device thus protecting doors made of transparent materials from tar deposits while oxygenating the firebox in the central part. The transparent material doors are fixed by pressure hinges (14) requiring no perforation or metal frame likely to reduce the visible space of the fireplace. In its lower part the device consists of a base (15) provided with a log grate (16) and an ashtray (17) as well as a sliding door (18) used for adjusting the draft.
