Abstract
Description
La présente invention a trait aux dispositifs autonomes de foyers équipés d'un système de circulation pour le chauffage de l'air et propres aussi bien à être montés dans une cheminée existante peu performante dans le but d'en améliorer les conditions d'utilisation qu'à former la base de cheminées nouvelles du type préfabriqué à haut rendement calorifique. The present invention relates to autonomous hearth devices equipped with a circulation system for air heating and suitable both for being mounted in an existing poorly performing chimney with the aim of improving the conditions of use which '' to form the basis of new chimneys of the prefabricated type with high calorific output.
Les perfectionnements qui font l'objet de l'invention ont plus spécialement pour but d'accrottre dans une mesure sensible le rendement calorifique du bois brûlé et le coefficient d'échange thermique, ainsi que de faciliter le branchement des dispositifs sur la gaine d'évacuation des fumées. The improvements which are the subject of the invention more specifically aim at increasing the heat output of the burnt wood and the heat exchange coefficient to a significant extent, as well as facilitating the connection of the devices to the sheath. smoke evacuation.
Le dispositif suivant l'invention est principalement remarquable en ce que la partie haute arrière de la carcasse qui forme le foyer proprement dit est reliée à la gaine d'évacuation par un conduit de récupération comprenant successivement une partie arrière descendante, deux parties horizontales inférieures prévues divergentes, deux parties latérales ascendantes et deux parties horizontales supérieures convergentes, la paroi interne de ce conduit étant constituée par la carcasse ellemême tandis que la paroi extérieure se trouve au moins partiellement disposée dans le passage prévu pour la circulation d'air A chauffer. The device according to the invention is mainly remarkable in that the upper rear part of the carcass which forms the hearth proper is connected to the evacuation sheath by a recovery duct successively comprising a descending rear part, two lower horizontal parts provided divergent, two ascending lateral parts and two converging upper horizontal parts, the internal wall of this duct being constituted by the carcass itself while the external wall is at least partially disposed in the passage provided for the circulation of air to be heated.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractEristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une coupe verticale d'un dispositif établai conformément A l'invention. The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a vertical section of a device established in accordance with the invention.
Fig. 2 est une vue en perspective avec arrachement illustrant la circulation des gaz chauds et fumées de combustion, l'enveloppe pour la circulation de l'air à chauffer ayant été supposée enlevée. Fig. 2 is a cutaway perspective view illustrating the circulation of hot gases and combustion fumes, the envelope for the circulation of the air to be heated having been assumed to be removed.
Le dispositif représenté en fig. 1 comprend essentiellement une carcasse en tôle 1 destinée à constituer le foyer pour la combustion du bois. Cette carcasse 1, à profil parallélépipédique, est ouverte sur son côté vertical antérieur, l'ouverture ainsi formée étant normalement fermée par une porte articulée 2 prévue transparente. Au-dessous de cette porte 2 est prévu un système de volets 3 pour le réglage de l'admission d'air dans la carcasse 1, ainsi qu'un élément 4 constituant chenêt pour retenir les bûches à brûler. The device shown in fig. 1 essentially comprises a sheet metal carcass 1 intended to constitute the hearth for the combustion of wood. This carcass 1, with a parallelepiped profile, is open on its anterior vertical side, the opening thus formed being normally closed by an articulated door 2 provided transparent. Below this door 2 is provided a shutter system 3 for adjusting the air intake in the carcass 1, as well as an element 4 constituting chenet for retaining the logs to be burned.
L'arrière de cette carcasse 1 est complétée par une pièce en tôle 5 qui recouvre la partie centrale de la paroi verticale carrière, le fond inférieur et chacune des deux parois latérales de ladite carcasse, en déterminant de la sorte un conduit pour ltévacuation des fumées et gaz chauds de combustion.Comme plus particulièrement montré en fig. 2, ce conduit dit de récupération", comporte
- une partie arrière descendante 6 qui communique avec l'intérieur de la carcasse 1 à travers une ouverture allongée 7 ménagée dans la partie arrière supérieure de ladite carcasse
- deux parties horizontales inférieures 8 prévues divergentes qui occupent l'arrière de la carcasse 1
- deux parties latérales ascendantes 9 disposées dans le prolongement des parties 8 précitées
- et deux parties latérales supErieures 10, prévues convergentes, qui communiquent avec la canalisation ou gaine 11 destinée A refouler les fumées et gaz chauds a l'extErieur. The rear of this carcass 1 is completed by a sheet metal part 5 which covers the central part of the vertical quarry wall, the bottom bottom and each of the two side walls of said carcass, thereby determining a duct for the evacuation of the fumes and hot combustion gases. As more particularly shown in fig. 2, this so-called recovery duct ", comprises
- a descending rear part 6 which communicates with the interior of the carcass 1 through an elongated opening 7 formed in the upper rear part of said carcass
- two divergent lower horizontal parts 8 which occupy the rear of the carcass 1
- two ascending side parts 9 arranged in the extension of the aforementioned parts 8
- And two upper side parts 10, converging, which communicate with the pipe or sheath 11 intended to discharge the fumes and hot gases outside.
Comme illustré en fig. 1, la liaison entre les parties convergentes 10 du conduit précité et la gaine 11 est opérée A l'aide d'un raccord 12 à profil légèrement tronconique. Ce raccord 12 est iatroduit dans la carcasse 1 pour être engagé verticalement à travers une ouverture ménagée dans la partie supérieure de la pièce 5, et ce jusqu'à ce que le sommet A petit diamètre dudit raccord se trouve enfile A l'intéw rieur de la base ouverte de la gaine 11. Un mécanisme A batonnette et A goujons 13 assure la retenue axiale du raccord 12. As illustrated in fig. 1, the connection between the converging parts 10 of the above-mentioned conduit and the sheath 11 is effected by means of a connector 12 with a slightly frustoconical profile. This connector 12 is iatroduit in the carcass 1 to be engaged vertically through an opening formed in the upper part of the part 5, and this until the apex A small diameter of said connector is threaded inside the open base of the sheath 11. A stick and stud mechanism 13 ensures the axial retention of the connector 12.
Au-dessous de ce raccord le plafond de la carcasse 1 est perce d'une ouverture de by-pass 14 qui fait ainsi directeLçnt couuniquer l'espace intérieur de ladite carcasse et la gaine 11, en court-circuitant de la sorte le conduit de récupEration formé par la pièce 5. Ce by-pass est commandé par un volet coulissant 15 manoeuvré horizontalement A l'aide d'une tirette 16 disposée sur l'avant du dispositif. Below this connection, the ceiling of the carcass 1 is pierced with a bypass opening 14 which makes the interior space of the carcass and the sheath 11 couunicate, thereby shorting the conduit of recovery formed by part 5. This bypass is controlled by a sliding shutter 15 operated horizontally using a pull tab 16 arranged on the front of the device.
La carcasse 1 ainsi constitué est logée A l'intrieur d'une enveloppé 17 qui s'applique troitetnent contre ses deux parois latrales opposées et qui par contre délimite un espace libre au niveau de la paroi horizontale inférieure, de la paroi verticale arrière ou fond et de la paroi horizontale supérieure. Bien entendu la paroi supérieure de cette enveloppe 17 est percée en 18 pour le passage du raccord 12 ; on prévoit par ailleurs des ouies inférieure 19 et supérieure 20 pour l'entrée de l'air froid dans l'espace libre susvisé, respectivement pour le refoulement de l'air chaud dans l'atmosphère. The carcass 1 thus formed is housed inside a casing 17 which is applied tightly against its two opposite lateral walls and which on the other hand delimits a free space at the level of the lower horizontal wall, the rear vertical wall or bottom and the upper horizontal wall. Of course the upper wall of this envelope 17 is pierced at 18 for the passage of the connector 12; it also provides lower 19 and upper 20 vents for the entry of cold air into the aforementioned free space, respectively for the discharge of hot air into the atmosphere.
Le fonctionnement et l'utilisation du dispositif ci-dessus décrit découlent des explications qui précèdent et se comprennent aisément. The operation and use of the device described above follow from the foregoing explanations and are easily understood.
Lors de l'allumage du feu, le volet 15 est amené à la position ouverte illustrée en fig. 1 de façon à obtenir un effet de tirage optimal ; les fumées et gaz chauds sont donc directement refoulés dans la gaine 11. Lorsque le feu est pris, l'utilisateur repousse le volet 15 en position fermée, de telle sorte que les fumees et gaz chauds sont obligés de traverser l'ouverture 7 pour circuler dans le conduit de récupération 6-8-9-10 avant d'être refoulés dans la gaine 11.Les essais ont montré que ce long parcours présentait deux avantages
- Par suite de la température très élevée de la paroi du conduit précité qui est formée par la carcasse ou foyer 1, les gaz chauds de nature combustible sont complètement brillés au lieu d'être refoulés dans l'atmosphère extérieure, cette post-combustion améliorant de manière très sensible le rendement calorifique du bois utilisé
- L'air qui circule dans l'espace libre ménagé entre la carcasse 1 et l'enveloppe 17 lèche la paroi extérieure du conduit sus-mentionné, si bien que le coefficient d'échange thermique est accru dans une mesure considérable.When the fire is started, the shutter 15 is brought to the open position illustrated in FIG. 1 so as to obtain an optimal drawing effect; the hot fumes and gases are therefore directly expelled into the sheath 11. When the fire is caught, the user pushes the shutter 15 in the closed position, so that the fumes and hot gases are forced to pass through the opening 7 to circulate in the recovery duct 6-8-9-10 before being forced back into the sheath 11.Tests have shown that this long journey has two advantages
- As a result of the very high temperature of the wall of the aforementioned conduit which is formed by the carcass or hearth 1, the hot gases of combustible nature are completely burnt instead of being discharged into the external atmosphere, this post-combustion improving very significantly the calorific yield of the wood used
- The air flowing in the free space provided between the carcass 1 and the casing 17 licks the outer wall of the above-mentioned conduit, so that the heat exchange coefficient is increased to a considerable extent.
Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'd titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
