Description

La présente invention se réfère à un appareil de chauffage à bois à foyer apparent,encastrable,sans superstructuro(fig.1)et ayant l'apparence d'une cheminée,fonctionnant à foyer ouvert ou fermé et pouvant s'adapter à toutes les .sortes de conduits de fumée à partir de 200 cm2 de section;spécialement étudier pour être encastré il est particulièrement conçu pour equiper les appartements munis de conduits de fumée collectifs à raccordement individuel(type "SCHUNT" ).The present invention relates to a wood-burning appliance with an apparent hearth, built-in, without superstructuro (fig. 1) and having the appearance of a chimney, operating with open or closed hearth and being able to adapt to all. kinds of smoke pipes from 200 cm2 section, specially designed to be built-in it is specially designed to equip apartments with collective smoke pipes with individual connection ("SCHUNT" type).

S'il existe sur le marché des poêle-cheminées à foyer apparent,ce sont généralement des appareils de grandes dimensions dont le foyer n'est que partiellement visible et dont l'infrastructure exige un habillage spécifique de la partie supérieure(hotte)l'evacuation des fumées se faisant toujours verticalement.If there are fireplaces with apparent hearths on the market, they are generally large devices whose hearth is only partially visible and whose infrastructure requires a specific covering of the upper part (hood). smoke evacuation always done vertically.

i De même,il existe sur le marché des poêle-cheminées munis de générateurs à air chaud ils sont munis de bouches de chaleur encastrées dans les habillages verticaux et provoquent inévitablement des salissures et s'ils sont équipés de panneaux en matériaux transparent ces derniers sont sertis dans des cadres métalliques peu esthétiques qui dissimulent en partie le foyer qui n'apparait alors que derrière des chassis.Ce mode de conception a également l'inconvénient de apparaitre des dépots de goudron opacifiant sur les parties transparentes.i Similarly, there are fireplaces on the market fitted with hot air generators, they are fitted with heat vents embedded in the vertical linings and inevitably cause soiling and if they are fitted with panels made of transparent materials these are set in unattractive metal frames that partially conceal the hearth, which only appears behind frames. This design method also has the disadvantage of appearing deposits of clouding tar on the transparent parts.

La présente invention vise au contraire à permettre d'installer un appareil de chauffage à bois de petites dimension dont le foyer est largement apparent.Cet appareil suivant l'invention est interressant dans le cas des appartements en ce qu'il se présente sous la forme d'un boitier encastrable,sans superstructures ouvert selon les modèles sur un,deux ou trois cotés et qu'il se branche sur tous les types de conduits de fumée y compis le "type SCHUNT".The present invention aims, on the contrary, to allow the installation of a small-sized wood-burning appliance, the hearth of which is largely apparent. of a built-in box, without superstructures open according to the models on one, two or three sides and that it plugs into all types of flues including the "SCHUNT type".

La position particulière de l'avaloir(2) situé à l'intérieur même du foyer dans sa partie supérieur permet ces avantages en ce que les fumées sont évacuées par la partie antérieur de l'appareil évitant ainsi les superstructures,toute fois elles peuvent aussi être évacuées par la partie supérieur.The particular position of the drain (2) located inside the hearth in its upper part allows these advantages in that the fumes are evacuated by the front part of the device thus avoiding the superstructures, however they can also be evacuated by the upper part.

Le principe de fonctionnement(voir fig.2)est que les fumées sont aspirées par lacombinaison di un effet de suçion par des- pressions(système de venturi)créer par un rétrécissement entre le déflecteur de flamme(3)et le caisson métallique(l'(l'ensemble forme avec l'avaloir(2)une cage de surchauffe des gaz(5) dans la partie antérieur ou débouche le manchon d'évacuation(6). des fumées et crée ainsi un syphon thermique tel que lorsque l'appareil est chaud il peut fonctionner portes ouvertes sur des conduits de fumées n'exédant pas 200cm2 de section per- metant ainsi un surcroît de chauffage par rayonnement.The principle of operation (see Fig.2) is that the fumes are sucked by lacombinaison d i a Motorized Suction effect by des- pressure (venturi system) creating a narrowing between the flame deflector (3) and the metal box ( the (the assembly forms with the drain (2) a gas overheating cage (5) in the front part or opens the evacuation sleeve (6). fumes and thus creates a thermal siphon such that when the appliance is hot it can operate with the doors open on flue pipes not exceeding 200cm2 in cross-section thus allowing additional heating by radiation.

Lorsque l'appareil fonctionne portes fermées(foyer fermé) le positionnement de l'avaloir inférieur(2) qui forme un angle de 20° avec les portes en matériaux transparents(13) (voir figure 3) et l'espace périphérique menagé autour des portes dont le volume n'exède pas le tirage minimum pour un foyer fermé,favorisent un courant d'air le long des portes(20) qui repousse les fumées évitant ainsi le dépôt des goudrons, le dessin en annexe donné à titre d'exemple permettra de mieux comprendre.cette idée et les caractéristiques qu'elle présente.When the appliance is operating with the doors closed (fireplace closed), position the lower drain (2) which forms an angle of 20 ° with the doors made of transparent materials (13) (see Figure 3) and the peripheral space provided around the doors whose volume does not exceed the minimum draft for a closed hearth, favor a draft along the doors (20) which repels fumes thus avoiding the deposit of tars, the drawing in appendix given by way of example will allow a better understanding of this idea and the characteristics it presents.

Les portes en matériaux transparents sont fixées sur des charniéres à pression(14)sur coussinets del"BAKELITE"(21) ne necéssitant ni-perforation ni cadre métallique,cela les rend peu perceptibles et n'entrave pas la bonne vision du foyer qui dans le cas de l'ouverture sur deux cotés décuple cette visibilité .The doors in transparent materials are fixed on pressure hinges (14) on "BAKELITE" pads (21) requiring neither perforation nor metal frame, this makes them not very noticeable and does not hamper the good vision of the hearth which in the case of opening on two sides increases this visibility tenfold.

Le caisson métallique(1)qui constitue l'appareil est doublé à l'intérieur d'un parement en briques réfractaires(7) qui emmagasine la chaleur et qui la réstitue à l'air circulant autour de l'appareil dans une double cloison(d)qui à pour effet d'une part d'isoler l'appareil des matériaux avoisin- nant et d'autre part de réchauffer l'air ambiant;la circulation d'air(10)se fait de bas en haut,l'air ambiant est aspiré à la base de l'appareil par un boitier de ventillation(11) puis circule autour du foyer à travers des chicannes(9)celles-ci ayant pour effet d'augmenter la surface des échanges thermiques,l'air ainsi réchauffé ressort dans la partie haute de l'appareil(12) entre l'avaloir inférieur et le parement en laiton(19) qui forme couvre-joint avec les divers élèments encastrants; l'avantage aquit avec ce système de reget d'air chaud est qu'il se répartit mieux dans l'air ambiant sans risquer de salire les surfaces verticales.The metal box (1) which constitutes the device is lined inside with a refractory brick facing (7) which stores the heat and which releases it to the air circulating around the device in a double partition ( d) which has the effect on the one hand of isolating the apparatus from the neighboring materials and on the other hand of heating the ambient air; the air circulation (10) is done from bottom to top, the ambient air is sucked in at the base of the device by a ventilation unit (11) then circulates around the hearth through chicannes (9), these having the effect of increasing the surface of the heat exchanges, the air thus reheated spring in the upper part of the appliance (12) between the lower drain and the brass facing (19) which forms a joint cover with the various recessed elements; The advantage with this hot air reget system is that it distributes better in the ambient air without risking dirtying the vertical surfaces.

Dans sa partie basse l'appareil est constitué d'un socle(15) dont la hauteur peut être variable,dans lequel s'inscrit un cendrier(17) et une grille foyére(16)destinée à retenir les bûches,ainsi qu'une porte coulissante (18) servant au réglage du tirage .In its lower part, the device consists of a base (15), the height of which can be variable, in which an ashtray (17) and a hearth grid (16) intended to hold the logs are inscribed, as well as a sliding door (18) for adjusting the draft.

Dans certains cas l'appareil sera équipé d'accessoires particuliers tel que:Grillies de cuisson qui viendra en recouvrement de la grille à bûche(16) fixée par deux charnières en arrière de celles-ci ou d'une grille à braises fixée do la même façon destinée à retenir les braises verticalement le long du parement en briques(7) sur la face antérieure de l'appareil.Un jeu de deux ou trois tourne broches monté sur une vis sans fin et actionné par un moteur mécanique ou élèc- trique pourra également être installé dans sa partie avant de l'avaloir(2) juste en avant du déflecteur de flamme(3).In some cases the appliance will be fitted with special accessories such as: Cooking grills which will cover the log grate (16) fixed by two hinges behind them or an ember grid fixed to the same way to hold the embers vertically along the brick facing (7) on the front of the device. A set of two or three spindles mounted on a worm screw and actuated by a mechanical or electric motor can also be installed in its front part of the drain (2) just in front of the flame deflector (3).

Le socle situé en bas de l'appareil(15) pourra également être plus important en hauteur et muni d'une porte abattante permettant d'utiliser ce volume en four de cuisson.The base located at the bottom of the appliance (15) could also be higher in height and provided with a drop-down door allowing this volume to be used in a baking oven.
