Abstract

The subject of the invention relates to a first certificate of addition applied to French Patent no. 2 477 678 of 7th March 1980 for a heat-recovery device for chimneys. It is constituted by the combination deriving from the closing of the hearth by a screen 5 which considerably reduces the draught, then by the circuit 11, 14 for recycling the air which is superheated by the hearth in the room even without intake of external draught air. It is intended to make possible an increase in the heating by recycling the preheated air directly in the room and to economise on fuel by eliminating the external intake of cold combustion air and by creating a natural or pulsed internal superheating convection.

Description

L'objet de l'invention concerne un premier certificat d'addition apporté au brevet français NO 2 477 678 du 7 Mars 1980, pour dispositif récupérateur de calories pour cheminées. The subject of the invention relates to a first addition certificate brought to French patent NO 2 477 678 of March 7, 1980, for a heat recovery device for fireplaces.

il est destiné à permettre une augmentation du chauffage par recyclage de l'air préchauffé directement dans le local et à économiser le combustible par suppression de l'appel extérieur de l'air froid de combustion et en créant une convection interne de surchauffage naturel ou pulsé. it is intended to allow an increase in heating by recycling the preheated air directly in the room and to save fuel by eliminating the external call of cold combustion air and by creating an internal convection of natural or pulsed superheating .

L ' expérience a démontré que l ' air extérieur réchauffé par la face extérieure du foyer et recycle comme air comburant activant le foyer alors que la veine chauffante la plus élevée en température partait par le conduit de cheminée, ce qui occasionnait non seulement une consommation importante de combustible mais encore un réchauffement insuffisant de la pièce par des températures extérieures très basses (- 11(0).  Experience has shown that the outside air heated by the outside face of the hearth and recycles as combustion air activating the hearth while the highest temperature heating vein left via the chimney flue, which not only caused significant consumption. of fuel but still insufficient heating of the room by very low outside temperatures (- 11 (0).

Le dispositif suivant l'invention supprime cet inconvénient et permet d'utiliser l'intégralité de la veine thermique pour le chauffage intérieur en supprimant l'appel d'air extérieur froid afin d'abord de réduire les pertes occasionnées par l ' éva- cuation des gaz chauds dans le conduit de cheminée et ensuite de diminuer la consommation de combustible. The device according to the invention eliminates this drawback and makes it possible to use the entire thermal stream for interior heating by eliminating the call for cold outside air in order first of all to reduce the losses caused by the evacuation. hot gases in the chimney flue and then reduce fuel consumption.

Il est constitué par la combinaison découlant de l'obtu- ration du foyer par un écran diminuant considérablement le tirage, ensuite par le circuit de recyclage de l'air surchauffé par le foyer dans la pièce même sans appel d'air de tirage extérieur. It consists of the combination resulting from the blocking of the hearth by a screen considerably reducing the draft, then by the circuit for recycling the air superheated by the hearth in the room even without the need for outside draft air.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 représente le dispositif dans son ensemble vu en élévation et en coupe longitudinale.
In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows the device as a whole seen in elevation and in longitudinal section.

La figure 2 montre schématiquement l'écran obturant le foyer sur sa face avant. Figure 2 shows schematically the screen closing the hearth on its front face.

La figure 3 représente le détail constructif de l'écran vu en perspective. Figure 3 shows the constructive detail of the screen seen in perspective.

L'appareil réchauffeur d'air, fig 1, 2, est constitué exactement comme celui décrit sur le brevet principal avec la sole 1, la plaque de fond du foyer 2 incorporée au conduit 3 avec diffuseur 4. The air heater, fig 1, 2, is constituted exactly like that described on the main patent with the hearth 1, the bottom plate of the hearth 2 incorporated into the duct 3 with diffuser 4.

Les faces latérales du foyer sont obturées par les parois de la cheminée. The side faces of the fireplace are closed off by the walls of the chimney.

La face avant du foyer est également obturée par un écran 5 coulissant dans le plan vertical et pouvant occuper la position 6 c'est-à-dire dégageant complétement la face avant. The front face of the hearth is also closed by a screen 5 sliding in the vertical plane and able to occupy position 6, that is to say completely releasing the front face.

Cette commande pouvant s'effectuer par crémaillère et manivelle 7 ou poignée 8. This control can be carried out by rack and crank 7 or handle 8.

L ' appel d 'air extérieur 9 est obturé préférentiellement par un registre 10. The outside air call 9 is preferably closed by a register 10.

Une bouche d'air 11 avec ventilateur 12 capte l'air de la pièce à chauffer donc un air interne non refroidi et l'as- pire dans le conduit 13. An air outlet 11 with fan 12 collects the air from the room to be heated, therefore an uncooled internal air and draws it into the duct 13.

Il sera propulsé dans la canalisation 3 débouchant dans le déflecteur 4. Il se répandra dans le local à chauffer par
l'ouverture 14, flèche 4.
It will be propelled in the pipe 3 opening into the deflector 4. It will spread in the room to be heated by
opening 14, arrow 4.

Cette veine d'air interne sera aspirée par l'orifice 12 et surchauffée par son contact avec la plaque de fond du foyer 2. This internal air stream will be sucked through the orifice 12 and overheated by its contact with the bottom plate of the hearth 2.

On aura ainsi un circuit A, B, d'air chaud. There will thus be a circuit A, B, of hot air.

Par contre le foyer 15 privé d'un apport direct d'air froid comburant donc avec tirage réduit maintiendra l'ignition par les fuites d'étanchéité d'obturation des parois, brûlera avec une intensité réduite. On the other hand, the hearth 15 deprived of a direct supply of oxidizing cold air, therefore with reduced draft, will maintain the ignition by leaks sealing the obturation of the walls, will burn with reduced intensity.

La veine d'air chaud qui s'échappera par la cheminée 16 sera réduite au minimum et l'économie de combustible très importante avec un résultat maximum pour la production de chaleur. The stream of hot air which will escape through the chimney 16 will be reduced to a minimum and the fuel economy very significant with a maximum result for the production of heat.

La face avant du foyer recevra un cadre 17 avec garniture d'étanchéité 18 telle que l'amiante, sur laquelle se déplacera l'écran 5 préférentiellement transparent le long de la coulisse 19 qui le guidera et sera solidaire du diffuseur 4 par une fixation sur la partie 17. The front face of the hearth will receive a frame 17 with gasket 18 such as asbestos, on which the preferably transparent screen 5 will move along the slide 19 which will guide it and will be integral with the diffuser 4 by a fixing on part 17.

Cette garniture 18 constitue également un freinage permettant d'obtenir, soit une obturation totale du foyer, soit partielle.  This lining 18 also constitutes braking making it possible to obtain either a total closure of the hearth, or a partial one.

L'ouverture totale assurant l'allumage de la cheminée, l'introduction du combustible. La fermeture progressive avant l'obturation totale en cours d'ignition provoquera l'accélération de la combustion. The total opening ensuring the ignition of the chimney, the introduction of fuel. Gradual closing before total shutdown during ignition will accelerate combustion.

Il est possible de combiner une marche mixte par la manoeuvre du volet 10 afin de régler l'appel d'air extérieur en inclinant également le registre d'alimentation en air extérieur se trouvant sur la sole, flèche C. It is possible to combine a mixed step by operating the shutter 10 in order to regulate the outside air draw by also tilting the outside air supply register located on the floor, arrow C.

Cette convection d'air interne permet d'obtenir un chauffage rapide du local avec une économie importante de combustible. This internal air convection allows rapid heating of the premises with significant fuel savings.

La partie haute du cadre 17 est fixée d'une façon étanche à la base du diffuseur 4. The upper part of the frame 17 is tightly fixed to the base of the diffuser 4.

L'écran 5 occupe une partie de l'espace prévu pour l'air extérieur entre le diffuseur et la hotte ce qui permet d'obtenir les circuits d'air décrits soit sur le brevet principal soit sur la présente addition par le jeu des vannes. The screen 5 occupies part of the space provided for the outside air between the diffuser and the hood, which makes it possible to obtain the air circuits described either on the main patent or on the present addition by the set of valves. .

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents, comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela, la conception générale de l'inven- tion qui vient d'être décrite.  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, like the materials used for their manufacture, without changing the general conception of the invention which has just been described.
