Abstract
Description
L'invention concerne un foyer ouvert à chaleur de convection forcée et naturelle, l'air chauffé à l'arrière du foyer ouvert pouvant être soufflé par le sol dans la pièce. Dans ledit arrière se trouve un échangeur de chaleur en acier inoxydable à plaques de chauffe en fonte.The invention relates to an open hearth with forced and natural convection heat, the heated air behind the open hearth being able to be blown from the floor into the room. In said rear there is a stainless steel heat exchanger with cast iron heating plates.
Le but de l'invention est d'obtenir un rendement élevé de chauffage et une agréable sensation de chaleur grâce à des différences minimales de température entre les couches d'air qui se trouvent respectivement près du sol et du plafond de la pièce à chauffer.The object of the invention is to obtain a high heating efficiency and a pleasant feeling of heat by means of minimum temperature differences between the layers of air which are located respectively near the floor and the ceiling of the room to be heated.
Un autre but consiste à rendre le foyer approprié pour tous les genres de combustibles solides et à maintenir la consommation de combustible aussi faible que possible.Another aim is to make the stove suitable for all kinds of solid fuels and to keep the fuel consumption as low as possible.
A ces fins, le foyer comprend, selon la principale caractéristique de l'invention, au moins un échangeur de chaleur placé contre la chambre de chauffe du foyer, au moins une gaine d'adduction d'air raccordée d'une part à l'ouverture d'entrée dudit échangeur de chaleur et débouchant d'autre part dans la moitié supérieure de la pièce à chauffer, au moins une gaine d'évacuation d'air raccordée d'une part à l'ouverture de sortie dudit échangeur de chaleur et débouchant d'autre part dans la moitié inférieure de la pièce à chauffer, et un ventilateur placé dans le circuit formé pour aspirer l'air dans ladite gaine d'adduction d'air et dans l'échangeur de chaleur et souffler l'air y chauffé de la gaine d'évacuation d'air dans la moitié inférieure de la pièce à chauffer.For these purposes, the hearth comprises, according to the main characteristic of the invention, at least one heat exchanger placed against the heating chamber of the hearth, at least one air supply duct connected on the one hand to the inlet opening of said heat exchanger and opening on the other hand into the upper half of the room to be heated, at least one air exhaust duct connected on the one hand to the outlet opening of said heat exchanger and opening on the other hand into the lower half of the room to be heated, and a fan placed in the circuit formed for sucking air into said air supply duct and into the heat exchanger and blowing the heated air there from the air exhaust duct into the lower half of the part to be heated.
Selon une autre caractéristique importante de l'invention, pour atteindre le but visé, le devant du foyer ouvert est recouvert d'une plaque frontale à portes et un tiroir-cendrier, dans laquelle des ouvertures d'adduction d'air pour l'air primaire sont prévues au-dessous de la grille de combustion pour brûler entre autres du charbon, des ouvertures d'adduction d'air au-dessus de la grille de combustion pour l'adduction également d'air primaire pour brûler entre autres du bois, et des ouvertures d'adduction d'air au-dessus de la grille de combustion et dans la partie supérieure de la porte pour l'adduction d'air secondaire.According to another important characteristic of the invention, to achieve the aim, the front of the open hearth is covered with a front plate with doors and an ashtray drawer, in which air supply openings for air primary are provided below the combustion grate to burn, among other things, coal, air supply openings above the combustion grate, also for the supply of primary air, to burn, inter alia, wood, and air supply openings above the combustion grate and in the upper part of the door for the secondary air supply.
A titre d'exemple sans aucun caractère limitatif, suit ci-dessous une description plus détaillée d'une forme choisie d'exécution du foyer ouvert conforme à l'invention. Cette description renvoie aux dessins annexés, dans lesquels :
- la fig. 1 est une vue de face d'un foyer ouvert non maçonné avec une porte en verre fermée et une ouverte;
- la fig. 2 est une coupe transversale d'un foyer ouvert maçonné;
- la fig. 3 est une vue en plan de la grille de combustion à mécanisme à tiges.
- fig. 1 is a front view of an open masonry fireplace with a closed glass door and an open one;
- fig. 2 is a cross section of an open masonry hearth;
- fig. 3 is a plan view of the combustion grate with rod mechanism.
Dans ces figures, on remarque qu'un échangeur de chaleur en acier inoxydable 3 est placé contre la paroi arrière 1 de la chambre de chauffe 2. Au haut bout cet échangeur de chaleur 3 est raccordé à deux gaines d'adduction d'air 4, qui débouchent chacune dans la partie supérieure de la pièce à chauffer. En bas, l'échangeur de chaleur.3 est raccordé au moyen d'un tuyau flexible 5 à un ventilateur 6* A ce ventilateur 6 sont raccordées deux gaines d'évacuation d'air 7, qui débouchent dans la partie inférieure de la pièce à chauffer et qui sont situées de préférence le plus possible de la surface du sol de la pièce et sont pourvues d'un clapet de réglage. Le ventilateur 6 aspire l'air plus froid qui se trouve dans la partie supérieure de la pièce dans les gaines d'adduction 4 et l'échangeur de chaleur 3, où il est chauffé, et souffle cet air chauffé, en passant par les gaines d'évacuation d'air 7, au-dessus du sol dans la partie inférieure de la pièce à chauffer.In these figures, it can be seen that a stainless steel heat exchanger 3 is placed against the rear wall. 1 of the
Tant les gaines d'adduction 4 que d'évacuation 7 d'air, qui peuvent être faites de matière rigide ou souple, sont recouvertes de préférence d'une grille 8. L'air à chauffer peut être aspiré aussi bien à l'intérieur qu'à l'extérieur de la pièce à chauffer et une ou plusieurs gaines d'évacuation d'air 7 peuvent également déboucher dans une autre pièce à chauffer.Both the supply ducts 4 and the
De chaque côté du foyer ouvert est placé un échangeur de chaleur 9 avec une ouverture d'entrée 10 prévue en bas dans la pièce à chauffer et en haut une ouverture de sortie 11 prévue dans la pièce à chauffer, l'air montant qui est chauffé dans les échangeurs de chaleur 9 se répandant dans la partie supérieure de la pièce à chauffer.On each side of the open hearth is placed a heat exchanger 9 with an inlet opening 10 provided at the bottom in the room to be heated and at the top an outlet opening 11 provided in the room to be heated, the rising air which is heated in the heat exchangers 9 spreading in the upper part of the part to be heated.
Le devant du foyer ouvert est recouvert d'une plaque frontale 12 pourvue de deux portes 13 en verre résistant à la chaleur et d'un tiroir-cendrier 14. Juste au-dessus de la grille de combustion 15 du foyer ouvert sont prévues dans les portes 13 des ouvertures d'adduction d'air 16 pour l'adduction d'air primaire. De même, dans le devant du tiroir-cendrier 14, des ouvertures d'adduction d'air 17 sont également prévues pour l'air primaire, ces ouvertures étant réglables et fermables au moyen d'un clapet 18. Au haut bout de chaque porte 13 une ouverture d'adduction d'air 19 est prévue pour l'air secondaire, lesquelles ouvertures sont également réglables et fermables au moyen d'un clapet 20. Lesdits clapets permettent donc un réglage de l'adduction d'air vers la chambre de chauffe 2 du foyer ouvert.The front of the open hearth is covered with a
Pour brûler du bois, on ferme les ouvertures d'adduction d'air 17, prévues dans le tiroir-cendrier 14 et pour brûler du charbon on laisse ces ouvertures ouvertes.To burn wood, the air supply openings 17, provided in the
La grille de combustion 15 est circulaire et repose librement dans une plaque fixe 21. Un mécanisme à tiges 22, qui peut être commandé de l'extérieur du foyer ouvert, peut tourner la grille de combustion 15, de sorte que le combustible qui y repose est secoué.The
Il va de soi que la forme, les dimensions, la matière et le nombre des accessoires décrits ci-dessus du foyer ouvert peuvent varier, que la disposition mutuelle des accessoires peut varier et que même certains de ces accessoires pourraient être remplacés par d'autres qui visent au même but.It goes without saying that the shape, dimensions, material and number of the accessories described above for the open hearth may vary, that the mutual arrangement of the accessories may vary and that even some of these accessories could be replaced by others. who aim for the same goal.
