Description

L'invention concerne un appareil de chauffage tel que poêle, foyer, fourneau, chaudière de chauffage central, four, séchoir et autres, pour la combustion de combustibles solides dans des espaces fermés et ouverts.The invention relates to a heating device such as stove, fireplace, stove, central heating boiler, oven, dryer and others, for the combustion of solid fuels in closed and open spaces.

Le but principal de l'invention est la réalisation d'un appareil de chauffage qui permet un réglage parfait du feu avec une très haute température de combustion et un grand rendement, et ce quelle que soit l'espèce de combustible solide utilisé.The main object of the invention is the production of a heating device which allows perfect control of the fire with a very high combustion temperature and a high yield, regardless of the species of solid fuel used.

Un autre but consiste en ce que le verre à l'épreuve du feu qui se trouve dans une porte pour la fermeture par exemple d'un foyer ou d'un poêle, soit maintenu libre de suie, de goudron et de condensation. Encore un autre but consiste en la réalisation d'une grille de longue durée de vie.Another object is that the fireproof glass which is in a door for closing, for example, a fireplace or a stove, is kept free of soot, tar and condensation. Yet another goal is to achieve a long life grid.

Ces buts sont atteints par l'appareil de chauffage tel qu'il est caractérisé dans les revendications.These objects are achieved by the heater as characterized in the claims.

On connaît du NL-A-29877 une grille réglable pour un appareil de chauffage, qui se compose d'un grille supérieure et d'une grille inférieure, qui sont coulissables l'une au-dessus de l'autre. La largeur de fente entre les barres de grille reste toutefois toujours égale sur toute la longueur, quelle qui soit la position des grilles l'une par rapport à l'autre. Par conséquent il n'est pas possible, avec cette grille réglable, de fermer graduellement les fentes dans la grille à partir de leurs extrémités afin d'amener plus d'air vers le centre du feu et d'obtenir ainsi une combustion meilleure et totale du combustible sur la grille. En outre dans ce brevet, aucun dispositif accessoire n'est décrit pour l'amenée d'air secondaire.There is known from NL-A-29877 an adjustable grid for a heating appliance, which consists of an upper grid and a lower grid, which are slidable one above the other. The width of the slot between the grid bars, however, always remains equal over the entire length, whatever the position of the grids relative to each other. Therefore it is not possible, with this adjustable grate, to gradually close the slots in the grate from their ends in order to bring more air towards the center of the fire and thus obtain a better and total combustion fuel on the grid. In addition, in this patent, no accessory device is described for the supply of secondary air.

On connaît aussi du CH-A-261310 une grille qui se compose d'un grille supérieure et d'une grille inférieure qui sont coulissables l'une par rapport à l'autre dans le but de régler la dimension des ouvertures de passage de la grille. Dans ce cas également, dans toutes les positions différentes des grilles, la largeur de fente entre les barres de grille sur toute leur longueur reste égale, de sorte que cette grille a le même inconvénient que celui décrit dans le NL-A-29877. Ici non plus, aucun dispositif accessoire n'est prévu pour l'amenée d'air secondaire.Also known from CH-A-261310 is a grid which consists of an upper grid and a lower grid which can be slid relative to each other in order to adjust the size of the passage openings of the wire rack. In this case also, in all the different positions of the grids, the slit width between the grid bars over their entire length remains equal, so that this grid has the same drawback as that described in NL-A-29877. Here, too, no accessory device is provided for the supply of secondary air.

On connaît aussi du DE-C-936230 une grille composée de deux parties de grille coulissables d'une manière rectiligne l'une par rapporta l'autre, la largeur de fente entre les barres de grille reste égale sur toute leur longueur, quelle que soit la position que prennent les grilles l'une par rapport à l'autre, de sorte que cette grille a aussi le même inconvénient que les grilles décrites dans les brevets néerlandais et suisse précités. Dans le cas de la grille tournante représentée dans les dessins, cet inconvénient est encore plus grand parce que quand on tourne la grille supérieure, à quelle occasion les fentes des grilles supérieure et inférieure arrivent à se superposer, la largeur de fente est la plus grande contre la périphérie de la grille au tieu du centre de ta gritte. ici non pius, it n'y a pas de dispositif accessoire prévu pour l'amenée d'air secondaire.DE-C-936230 also discloses a grid made up of two grid parts which can be slid in a rectilinear manner with respect to each other, the width of the slot between the grid bars remains equal over their entire length, whatever or the position that the grids take in relation to each other, so that this grid also has the same drawback as the grids described in the abovementioned Dutch and Swiss patents. In the case of the rotating grid shown in the drawings, this disadvantage is even greater because when the upper grid is rotated, on which occasion the slots of the upper and lower grids happen to overlap, the width of the slot is greatest against the periphery of the grid at the center of your gritte center. here not worse, there is no accessory device provided for the supply of secondary air.

Au contraire, l'appareil de chauffage selon l'invention et décrit dans la première partie caractéristique de la revendication 1, a l'avantage que le centre du feu pent recevoir plus d'air primaire que sa périphérie. Ceci permet une meilleure combustion du combustible pour toutes les capacités de feu, en fonction de la position de la grille mobile par rapport à la grille fixe. Ceci est obtenu par la fermeture graduelle des extrémités des ouvertures de passage qui sont situées à la périphérie des grilles. Un avantage supplémentaire est que là où il y a le plus de feu sur la grille et où le plus d'air est amené, cet endroit est le plus refroidi, grâce à quoi la durée de vie de la grille est considérablement allongée.On the contrary, the heating device according to the invention and described in the first characteristic part of claim 1, has the advantage that the center of the fire can receive more primary air than its periphery. This allows better fuel combustion for all fire capacities, depending on the position of the movable grate relative to the fixed grate. This is achieved by gradually closing the ends of the passage openings which are located at the periphery of the grids. An additional advantage is that where there is the most fire on the grate and where the most air is brought in, this place is the most cooled, thanks to which the life of the grate is considerably extended.

Un autre avantage de la construction spéciale de l'appareil de chauffage selon l'invention est l'amenée d'air secondaire à travers l'ouverture, qui débouche verticalement dans l'espace de combustion prévue sous la porte en verre. En outre on forme un rideau d'air parfaitement pur contre la porte en verre, grâce à quoi celle-ci reste impeccablement propre. Un autre avantage est que la pollution de l'air par le monoxyde de carbonne est réduite et que le volume des cendres est rédui à un minimum.Another advantage of the special construction of the heater according to the invention is the supply of secondary air through the opening, which opens vertically into the combustion space provided under the glass door. In addition, a perfectly clean air curtain is formed against the glass door, which keeps it perfectly clean. Another advantage is that air pollution by carbon monoxide is reduced and the volume of ash is reduced to a minimum.

A titre d'exemple il suit ci-dessous une description plus détaillée d'une forme de réalisation de l'appareil de chauffage choisi en conformité avec l'invention. Cette description renvoie aux dessins annexés, dans lesquels:

  • la fig. 1 représente une coupe transversale d'un foyer ouvert à clapet économisant et porte en verre;
  • la fig. 2 représente la grille supérieure fixe en perspective;
  • la fig. 3 représente la grille inférieure déplaçable en perspective;
  • la fig. 4 représente une vue d'en haut des deux grilles placées l'une au-dessus de l'autre dans une plaque fixe;
  • la fig. 5 représente une coupe longitudinale suivant la ligne V-V de la fig. 4;
  • la fig. 6 représente une vue d'en haut des deux grilles placées l'une au-dessus de l'autre dans la plaque fixe, mais la grille déplaçable étant partiellement déplacée.
By way of example, below follows a more detailed description of an embodiment of the heating appliance chosen in accordance with the invention. This description refers to the attached drawings, in which:
  • fig. 1 shows a cross section of an open hearth with saving valve and glass door;
  • fig. 2 shows the fixed upper grid in perspective;
  • fig. 3 shows the lower grid movable in perspective;
  • fig. 4 shows a top view of the two grids placed one above the other in a fixed plate;
  • fig. 5 shows a longitudinal section along the line VV of FIG. 4;
  • fig. 6 shows a top view of the two grids placed one above the other in the fixed plate, but the movable grid being partially displaced.

Dans ces figures, on remarque lefoyerouvert 1 à clapet économisant 2, qui est fermé par une porte en verre 3. En bas dans le foyer ouvert 1, une grille fixe 5 est placée dans une plaque fixe 4 et est pourvue d'ouvertures de passage 6 oblongues à bords longitudinaux parallèles. Sous et contre cette grille, il y a une deuxième grille 7 de la même dimension que la grille 5, suspendue d'une manière déplaçable dans deux profilés guides 8-9, qui sont fixés au côté inférieur de la plaque 4. Dans cette deuxième grille 7 sont également prévues des ouvertures de passage 10 oblongues, mais dont chaque fois un des bords longitudinaux a la forme d'un V obtus, de sorte que chaque ouverture de passage est le plus large dans sa partie centrale et est plus large que la distance entre les bords longitudinaux des ouvertures de passage 6 de la première grille 5. Ces ouvertures de passage 6-10 dans les deux grilles 5-7 devraient aussi pouvoir avoir d'autres formes et peuvent se trouver sous la forme de petits trous, ouvertures ovales, rondes ou sous d'autres formes, placés en triangle, à condition qu'il soit veillé à ce que le passage de chaque ouverture de passage 10 formée dans la grille 7 soit plus grande au centre de cette grille. C'est ainsi que cette grille pourrait être pourvue au centre d'ouvertures qui sont plus grandes que celles prévues près des côtés latéraux de la grille, ou bien on pourrait prévoir au centre de la grille plus d'ouvertures que près des bords latéraux de celle-ci. Cette grille 7 est pourvue au devant d'une manette 11, qu'on peut actionner sur le devant du foyer ouvert pour déplacer ladite grille 7 par rapport à la grille 5. Le passage de l'air est maximal quand les ouvertures de passage 6-10 des deux grilles 5-7 sont juste superposées. Mais quand la grille inférieure 7 est déplacée jusqu'à ce que les ouvertures de passage 6 de la grille 5 sont fermées, l'air ne peut plus passer. La grille 7 peut aussi être déplacée partiellement dans les profilés de guidage 8-9 jusqu'à ce que les extrémités des ouvertures de passage 6 de la grille 5 sont fermées et que seule la partie centrale en reste libre. Dans ce cas, chaque ouverture de passage a la forme d'un triangle. La partie centrale de la grille reçoit alors plus d'air que set côtés latéraux, de sorte que la combustion du combustible sur la grille est le plus vive au centre du combustible. Un réglage efficace de l'air est donc possible en fonction de la taille du feu qu'on désire obtenir. Sous la porte en verre 3, de préférence une ouverture oblongue 12 est prévue pour laisser pénétrer de l'air secondaire dans la chambre de combustion 13, et dans cettes chambre de combustion 13, un profilé 14 guidant l'air est placé devant ladite ouverture pour faire dévier l'air verticalement contre le côté intérieur de la porte en verre 3, où les gaz non brûlés sont mélangés dans la chambre de combustion 13 à l'air secondaire fraîchement amené. De ce fait, un rideau d'air parfaitement pur avec ±20% d'oxygène pur est formé contre la porte en verre 3, grâce à quoi celle-ci reste impeccablement propre.In these figures, we note the open hearth 1 with a saving valve 2, which is closed by a glass door 3. Below in the open hearth 1, a fixed grid 5 is placed in a fixed plate 4 and is provided with passage openings 6 oblong with parallel longitudinal edges. Under and against this grid, there is a second grid 7 of the same dimension as the grid 5, suspended in a movable manner in two guide sections 8-9, which are fixed to the lower side of the plate 4. In this second grid 7 are also provided with oblong passage openings 10, but each of which one of the longitudinal edges has the shape of an obtuse V, so that each passage opening is the widest in its central part and is wider than the distance between the longitudinal edges of the passage openings 6 of the first grid 5. These openings passage 6-10 in the two grids 5-7 should also be able to have other forms and can be in the form of small holes, oval, round openings or in other forms, placed in a triangle, provided that it is ensured that the passage of each passage opening 10 formed in the grid 7 is greater in the center of this grid. Thus this grid could be provided in the center with openings which are larger than those provided near the lateral sides of the grid, or else one could provide in the center of the grid with more openings than near the lateral edges of this one. This grid 7 is provided at the front with a lever 11, which can be actuated on the front of the open hearth to move said grid 7 relative to the grid 5. The passage of air is maximum when the passage openings 6 -10 of the two grids 5-7 are just superimposed. But when the lower grid 7 is moved until the passage openings 6 of the grid 5 are closed, the air can no longer pass. The grid 7 can also be partially displaced in the guide profiles 8-9 until the ends of the passage openings 6 of the grid 5 are closed and only the central part remains free. In this case, each passage opening has the shape of a triangle. The central part of the grate then receives more air than the lateral sides, so that the combustion of the fuel on the grate is most intense in the center of the fuel. An effective air adjustment is therefore possible depending on the size of the fire you want to obtain. Under the glass door 3, preferably an oblong opening 12 is provided to allow secondary air to enter the combustion chamber 13, and in these combustion chamber 13, a profile 14 guiding the air is placed in front of said opening. to deflect the air vertically against the interior side of the glass door 3, where the unburned gases are mixed in the combustion chamber 13 with the freshly supplied secondary air. As a result, a perfectly pure air curtain with ± 20% pure oxygen is formed against the glass door 3, thanks to which the latter remains impeccably clean.
