The installation is noteworthy in that the gully 44 mounted at the upper portion of the hearth is transversely separated in two, in order to define a section S1 at the front for the passage of gases forming a siphon in order to prevent them from returning to the hearth, and a section S2 at the rear for passage with a depression effect accelerating the speed of the smoke. The invention relates to all solid fuels.

Description

Le Certificat d'Addition concerne une installation de chauffage domestique à foyer fermé utilisant un combustible solide du type bois ou ses dérivés. The Certificate of Addition concerns a domestic heating installation with a closed hearth using a solid fuel of the wood type or its derivatives.

L'objet de l'invention se rattache au secteur technique des appareils à combustion à usage domestique pour combustibles solides. The object of the invention relates to the technical sector of combustion appliances for domestic use for solid fuels.

On rappelle que selon la Demande de Brevet en particulier la revendication 1, l'installatio*st remarquable en ce qu'elle comprend en combinaison à partir d'un foyer fermé de préference en fonte, un échangeur thermique des fumées chaudes interposé dans le conduit audessus du foyer pour réinjecter la chaleur dans la pièce à chauffer, un dispositif de régulation automatique à dépression de la combustion avec contrôle precis de la température, un dispositif d'admission d'air supplémentaire ou secondaire pour obtenir une combustion complète et propre du combustible, et une porte vitrée de fermeture du foyer à relevage équilibré et à vitre amovible pour faciliter 1 'entretien.  It will be recalled that according to the Patent Application in particular claim 1, the installation is remarkable in that it comprises, in combination from a closed hearth preferably in cast iron, a heat exchanger for hot fumes interposed in the duct. above the hearth to inject the heat back into the room to be heated, an automatic vacuum regulation device for combustion with precise temperature control, an additional or secondary air intake device to obtain complete and clean combustion of the fuel , and a glass door closing the fireplace with balanced lift and removable glass to facilitate maintenance.

Selon l'addition, on a voulu améliorer encore les performances de l'installation par des aménagements complémentaires destinés à augmenter la surface d'échange air-combustible, à accélerer la vitesse des fumées et à siphonner les gaz. According to the addition, it was desired to further improve the performance of the installation by additional arrangements intended to increase the air-fuel exchange surface, to accelerate the speed of the fumes and to siphon the gases.

Pour cela, selon une première caractéristique, l'avaloir monté à la partie supérieure du foyer est séparé transversalement en deux, afin de définir à l'avant une section de passage des gaz formant siphon pour empêcher leur retour dans le foyer, et à l'arrière une section de passage à effet dépressionnaire accélérant la vitesse des fumées. For this, according to a first characteristic, the drain mounted at the upper part of the hearth is divided transversely into two, in order to define at the front a gas passage section forming a siphon to prevent their return into the hearth, and at the 'rear a passage section with low pressure effect accelerating the speed of smoke.

Selon une autre caractéristique , la séparation transversale de l'avaloir est constituée par un tube profilé débouchant latéralement sur les faces de l'avaloir pour former un échangeur transversal de chaleur augmentant la surface d-'échange air-combustible. According to another characteristic, the transverse separation of the drain consists of a profiled tube opening laterally on the faces of the drain to form a transverse heat exchanger increasing the air-fuel exchange surface.

Ces caractéristiques et d'autres encore ressortiront de la description qui suit. These characteristics and others will emerge from the description which follows.

Pour fixer l'objet de l'invention, sans toutefois le limiter, dans le dessin annexé :
La figure 1 est une vue en coupe de l'installation conforme à l'invention.To fix the subject of the invention, without however limiting it, in the appended drawing:
Figure 1 is a sectional view of the installation according to the invention.

la figure 2 est une vue en coupe transversale considérée suivant la ligne 2-2 de la figure 1. Figure 2 is a cross-sectional view taken along line 2-2 of Figure 1.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant sous une forme non limitative de réalisation illustrée aux figures du dessin. In order to make the object of the invention more concrete, it is now described in a nonlimiting embodiment illustrated in the figures of the drawing.

On rappelle tout d'abord les principaux composants de l'installation telle que décrite dans la demande de brevet et les deux premiers Certificats d'addition dont le déposant est également titulaire. First of all, we recall the main components of the installation as described in the patent application and the first two certificates of addition of which the applicant is also the holder.

On voit un foyer (1) en fonte, généralement porté par un caisson métallique (2) ouvert sur le dessus et contenant un cendrier (3). Un châssis vitré (4) à relevage équilibré forme l'avant du foyer, et une tirette de décendrage oscillante (D) est interposée entre les deux parties (la-ld) de la sole, constituant un double coeur. We see a hearth (1) in cast iron, generally carried by a metal box (2) open on top and containing an ashtray (3). A glazed frame (4) with balanced lifting forms the front of the hearth, and an oscillating ash removal pull (D) is interposed between the two parts (la-ld) of the hearth, constituting a double core.

Conformément aux dépôts précédents, l'air admis sous le foyer par une canalisation (30),traverse en grande partie la grille de la sole, et passe également entre les deux parties (la-ld) de la sole, pour être dirigé et remonter à l'avant le long de la vitre pour opérer le désemfumage, et à l'arrière le long de la paroi de fond du foyer pour entraîneur directement l'air ainsi préchauffé vers l'avaloir en évitant les dépôts de goudron. In accordance with the preceding deposits, the air admitted under the hearth by a pipe (30), largely crosses the grill of the hearth, and also passes between the two parts (la-ld) of the hearth, to be directed and ascended at the front along the window to operate the smoke extraction, and at the rear along the bottom wall of the hearth for direct entrainment of the air thus preheated towards the downstream avoiding the deposit of tar.

Au-dessus de l'avaloir un échangeur thermique (17) emmagasine la chaleur des fumées et la réinjecte dans la pièce à chauffer en passant dans la hotte décorative (19) et des ouvertures supérieures à filtre (18). Above the drain, a heat exchanger (17) stores the heat of the fumes and reinjects it into the room to be heated, passing through the decorative hood (19) and upper filter openings (18).

Un volet de contrôle de tirage (V) est placé entre l'avaloir et l'échangeur thermique, tandis qu'un clapet automatique (C) de réglage d'entrée d'air de combustion est disposé dans la canalisation (30) et est relié à un thermostat (T). A draft control flap (V) is placed between the drain and the heat exchanger, while an automatic flap (C) for adjusting the combustion air inlet is placed in the pipe (30) and is connected to a thermostat (T).

Selon les caractéristiques de l'invention, l'avaloir (44) est composé de deux éléments (44a-44b) bridés l'un au dessus de l'autre et conformés pour déporter vers l'arrière la partie supérieure de raccordement avec l'échangeur. According to the characteristics of the invention, the drain (44) is composed of two elements (44a-44b) flanged one above the other and shaped to offset back the upper part of connection with the exchanger.

Le premier élément (44a) présente transversalement un tube profilé (44c) débouchant latéralement de l'avaloir pour évacuer dans la hotte l'air chaud et ainsi augmenter la surface d'echange thermique. Ce tube délimite à lavant des sections (S1) (S2) formant des venturis. The first element (44a) has transversely a profiled tube (44c) opening laterally from the drain to evacuate the hot air in the hood and thus increase the heat exchange surface. This tube delimits at the front sections (S1) (S2) forming venturis.

Le venturi avant plus étroit permet le siphonnage des gaz empêchant leur retour dans le foyer, tandis que le venturi arrière plus large à un effet dépressionnaire piégeant les gaz et accélérant la vitesse des fumées-. A titre indicatif, l'expérience montre que la largeur (21) du venturi avant doit être sensiblement égale à la moitiée de la largeur (Q2) du venturi arrière pour obtenir les meilleurs résultats. The narrower front venturi allows siphoning of the gases preventing their return in the hearth, while the wider rear venturi has a low pressure effect trapping the gases and accelerating the speed of the fumes. As an indication, experience shows that the width (21) of the front venturi must be substantially equal to half the width (Q2) of the rear venturi to obtain the best results.

Les avantages ressortent bien de la description. The advantages are apparent from the description.

L'invention ne se limite aucunement à celui de ses modes d'appli cation non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées , elle en embrasse au contraire toutes les variantes.  The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts having been more particularly indicated, on the contrary it embraces all variants.
