Description

Domaine de l'inventionField of the invention

La présente invention concerne un brûleur à gaz, concrètement du type de ceux qui sont alimentés en un gaz liquéfié et qui, normalement, sont installés sur une bouteille contenant le gaz liquéfié, soit par intercalation d'un détendeur pour obtenir une pression basse du gaz d'application domestique, soit directement sur la même bouteille.The present invention relates to a gas burner, concretely of the type of those which are fed with a liquefied gas and which, normally, are installed on a bottle containing the liquefied gas, or by intercalation of a pressure reducer to obtain a low pressure of the gas domestic application, either directly on the same bottle.

Etat de l'artState of the art

Les brûleurs du type exposé qui sont destinés à chauffer ce qui est connu sous le nom de poêles à paella, c'est à dire, les récipients en fer en guise de poêle, peu profonds et avec deux anses, servant à faire la paella, sont constitués par une disposition spéciale constituée par un tore tubulaire, simple ou double, qui est pourvu d'orifices de flamme sur sa zone supérieure et d'un tube radial de connexion, à travers une conduite flexible, à une bouteille de gaz liquéfié.The burners of the exposed type which are intended to heat what is known under the name of paella stoves, that is to say, the iron containers as a stove, shallow and with two handles, used to make the paella, are constituted by a special arrangement constituted by a tubular torus, single or double, which is provided with flame orifices on its upper zone and a radial connection tube, through a flexible pipe, to a bottle of liquefied gas.

Cette disposition spéciale des brûleurs de ce type est due au fait que les brûleurs conventionnels qui sont incorporés dans les fourneaux installés sur les bouteilles de gaz liquéfié sont formés par des pièces de fonte métallique ou en acier émaillé, qui sont dans tous les cas de diamètre réduit et qui ne permettent pas de chauffer de manière uniforme dans toute son étendue le fond de la poêle à paella, ce qui rend impossible son utilisation pour la préparation appropriée de paellas sur la propre bouteille de gaz liquéfié.This special arrangement of the burners of this type is due to the fact that the conventional burners which are incorporated in the furnaces installed on the bottles of liquefied gas are formed by pieces of metal or enamelled steel cast iron, which are in any case of diameter. reduced and which do not allow to heat evenly throughout its extent the bottom of the paella pan, which makes it impossible its use for the proper preparation of paellas on the own bottle of liquefied gas.

Sommaire de l'inventionSummary of the invention

Afin de faire possible la disposition d'un brûleur pour bouteille de gaz liquéfié qui soit approprié pour la préparation de paellas, on a adopté la solution de réaliser un brûleur de grand diamètre et de poids léger permettant son insertion directe dans !e robinet avec détendeur accouplé à la valve de la bouteille, et qui fournisse la chaleur adéquate à la surface de la poêle à paella. Pour ce faire, on a établit la construction du brûleur au moyen de pièces conformées de tôle métallique.In order to make possible the provision of a burner for a bottle of liquefied gas which is suitable for the preparation of paellas, the solution has been adopted to realize a large diameter and light weight burner allowing direct insertion into the regulator valve coupled to the bottle valve and providing adequate heat to the surface of the paella pan. To do this, the construction of the burner was established by means of shaped pieces of sheet metal.

Selon la précédente solution, on a développé le brûleur à gaz objet de l'invention, destiné à être alimenté en un gaz liquéfié et apte à être installé sur une bouteille contenant le gaz liquéfié, caractérisé en ce qu'il est constitué par une pièce supérieure à structure laminaire conformée qui est disposée solidairement sur une autre pièce inférieure, également à structure laminaire conformée et de diamètre équivalent à celui de ladite pièce supérieure, les deux pièces supérieure et inférieure conformant conjointement une chambre de mélange du gaz combustible avec le gaz comburant, de manière que, dans sa conformation, ladite pièce supérieure présente, d'une part, un collier périmétral en forme de canal formant une concavité en vis à vis de ladite chambre de mélange et qui présente sa paroi périphérique pourvue d'orifices de sortie dudit mélange combustible et de siège des flammes produites par l'ignition de celle-ci et, d'autre part, ladite pièce supérieure présente une protubérance centrale supérieure à hauteur réduite disposée avec sa concavité orientée vers ladite pièce inférieure, laquelle pièce inférieure présente une protubérance centrale inférieure qui est disposée avec sa convexité orientée vers la concavité de ladite protubérance centrale supérieure et qui est pourvue d'un orifice central dans lequel est axialement fixé un élément tubulaire qui, étant conducteur de la veine de gaz combustible et étant pourvu d'ouvertures latérales d'aspiration du gaz comburant, émerge par son embouchure supérieure jusqu'à la proximité de la surface de la face concave de ladite protubérance centrale supérieure.According to the previous solution, the gas burner object of the invention was developed, intended to be fed with a liquefied gas and suitable for being installed on a bottle containing the liquefied gas, characterized in that it consists of a single piece upper laminar shaped structure which is arranged integrally on another lower part, also of shaped laminar structure and of diameter equivalent to that of said upper part, the two upper and lower parts jointly forming a mixing chamber of the fuel gas with the oxidizing gas , so that, in its conformation, said upper piece has, on the one hand, a channel-shaped perimeter collar forming a concavity opposite said mixing chamber and which has its peripheral wall provided with outlet orifices fuel and seat mixture of the flames produced by the ignition thereof and, t, said upper piece has an upper central protrusion at reduced height disposed with its concavity oriented towards said lower piece, which lower piece has a lower central protuberance which is arranged with its convexity oriented towards the concavity of said upper central protuberance and which is provided a central orifice in which is axially fixed a tubular element which, being conducting the fuel gas stream and being provided with lateral combustion gas suction openings, emerges from its upper mouth to the vicinity of the surface the concave face of said upper central protuberance.

Description détaillée d'une réalisation de l'inventionDetailed description of an embodiment of the invention

Sur les Figures 1 et 2 on observe que le brûleur à gaz 1 est constitué par une pièce supérieure 2 de structure laminaire conformée qui a un diamètre supérieur à celui qui est habituel dans les brûleurs conventionnels d'une cuisine domestique et qui est disposée solidairement sur une autre pièce inférieure 3, également de structure laminaire conformée, qui a un diamètre équivalent à celui de ladite pièce supérieure 2. Les deux pièces supérieure 2 et inférieure 3 configurent conjointement une chambre 7 de mélange du gaz combustible avec le gaz comburant. Dans sa conformation, la pièce supérieure 2 présente, d'une part, un collier périmétral 4 en forme de canal qui forme une concavité en vis à vis de la chambre 7 de mélange et qui présente sa paroi périphérique pourvue d'orifices 5 de sortie du mélange combustible et de siège des flammes produites par l'ignition dudit mélange combustible et, d'autre part, ladite pièce supérieure 2 présente une protubérance centrale supérieure 6 de hauteur réduite disposée avec sa concavité orientée vers la pièce inférieure 3, laquelle, à son tour, présente une protubérance centrale inférieure 10 qui est disposée avec sa convexité orientée vers la concavité de la protubérance centrale supérieure 6.On the Figures 1 and 2 it is observed that the gas burner 1 is constituted by an upper piece 2 of shaped laminar structure which has a diameter greater than that which is usual in conventional burners of a domestic kitchen and which is arranged integrally on another lower part 3, also of shaped laminar structure, which has a diameter equivalent to that of said upper part 2. The two upper and lower parts 2 and 3 jointly configure a chamber 7 for mixing the fuel gas with the oxidizing gas. In its conformation, the upper piece 2 has, on the one hand, a perimetral collar 4 in the form of a channel which forms a concavity opposite the mixing chamber 7 and which has its peripheral wall provided with outlet orifices 5 of the fuel mixture and seat of the flames produced by the ignition of said combustible mixture and, on the other hand, said upper part 2 has an upper central protuberance 6 of reduced height arranged with its concavity oriented towards the lower part 3, which, at in turn, has a lower central protrusion 10 which is disposed with its convexity oriented towards the concavity of the upper central protuberance 6.

Sur la Figure 3 on précise les détails qui ne sont pas visibles sur les Figures antérieures et on constate que le brûleur à gaz 1 est constitué par une chambre de mélange 7 configurée entre les deux pièces supérieure 2 et inférieure 3 qui sont essentiellement discoïdes et qui sont superposées axialement et en rapport périmétralement par le collier périmétral 4 en forme de canal, de hauteur réduite, de la pièce supérieure 2. Dans les orifices 5 de sortie du mélange combustible, disposés sur la paroi périphérique dudit collier périmétral 4 en forme de canal, il se produit l'inflammation dudit mélange combustible sous forme d'une couronne de flammes. La pièce inférieure 3 dispose d'un orifice central 8 dans lequel est fixée une douille tronconique 9 dans laquelle se produit l'aspiration de l'air nécessaire pour le mélange combustible par l'action de la dépression créée par le gaz émis à pression par un injecteur. Le brûleur 1 est connecté directement avec une bouteille de gaz liquéfié, à travers ladite douille tronconique 9 et un robinet pourvu d'un détendeur. L'embouchure la plus petite de ladite douille tronconique 9 est disposée à l'intérieur de la chambre 7 de mélange de manière que ladite embouchure la plus petite se situe à une distance très réduite de la face concave 6A de la protubérance centrale supérieure 6.On the Figure 3 the details which are not visible in the previous figures are specified and it is noted that the gas burner 1 consists of a mixing chamber 7 configured between the two upper and lower parts 2 which are essentially discoidal and which are superposed axially and in relation perimetrically by the perimetral collar 4 in the form of a channel, of reduced height, of the upper part 2. In the outlet orifices 5 of the fuel mixture, arranged on the peripheral wall of said perimetral collar 4 in the form of a channel, it occurs the ignition of said combustible mixture in the form of a ring of flames. The lower piece 3 has a central orifice 8 in which is fixed a frustoconical socket 9 in which occurs the suction of the air necessary for the fuel mixture by the action of the depression created by the gas emitted at pressure by an injector. The burner 1 is connected directly with a bottle of liquefied gas, through said frustoconical socket 9 and a valve provided with a pressure reducer. The smallest mouth of said frustoconical socket 9 is disposed inside the mixing chamber 7 so that said smaller mouth is at a very small distance from the concave face 6A of the upper central protuberance 6.

Par ailleurs, la pièce inférieure 3 présente une configuration essentiellement tronconique renversée de hauteur réduite, qui, par sa face concave 3A, présente au centre ladite protubérance centrale inférieure 10, qui est tronconique et de hauteur réduite, et dont la base la plus petite est configurée sous forme annulaire 10A. La périphérie de ladite pièce inférieure 3 adopte une configuration 3B de section droite mixte (courbée-rectiligne), dans laquelle sa parte rectiligne configure une zone périmétrale cylindrique réduite qui s'étend dans un collier 11 servant de siège et de prise à la pièce supérieure 2.Furthermore, the lower part 3 has a substantially inverted frustoconical configuration of reduced height, which, by its concave face 3A, has in the center said lower central protuberance 10, which is frustoconical and of reduced height, and whose smallest base is configured in annular form 10A. The periphery of said lower piece 3 adopts a configuration 3B of mixed straight section (curved-rectilinear), in which its rectilinear portion configures a reduced cylindrical perimetric zone which extends in a collar 11 serving as a seat and grip to the upper piece 2.

De manière analogue, la pièce supérieure 2 présente une configuration essentiellement sous forme d'une cuvette qui présente une paroi cylindrique 2A de hauteur réduite qui, périphériquement, s'étend dans un collier dièdrique qui se différencie dans une première partie 2B co-planaire avec la base 2C de ladite cuvette et une deuxième partie 2D tronconique qui est pourvue de moyens de d'assise et fixation 12 sur le collier 11 de la pièce inférieure 3 et qui présente sur sa surface les orifices 5 de sortie du mélange combustible et de siège des flammes d'une couronne de feu.Similarly, the upper part 2 has a configuration essentially in the form of a bowl which has a cylindrical wall 2A of reduced height which, peripherally, extends in a dichromic collar which is differentiated in a first co-planar portion 2B with the base 2C of said bowl and a second frustoconical 2D portion which is provided with seating and fixing means 12 on the collar 11 of the lower part 3 and which has on its surface the outlets 5 of the fuel mixture and seat of the flame of a fire crown.

Lesdits orifices 5 de sortie du mélange combustible et de siège des flammes présentent un calibre unitaire équilibré globalement et sont repartis de manière régulière en deux files sur la surface de ladite deuxième partie 2D tronconique du collier de la pièce supérieure 2, les orifices 5 de la file supérieure étant de plus grand diamètre que les orifices 5 de la file inférieure.Said outlet orifices 5 of the fuel mixture and flame seat have a unitary caliber globally balanced and are distributed regularly in two rows on the surface of said second frustoconical 2D portion of the collar of the upper part 2, the orifices 5 of the upper file being of larger diameter than the orifices 5 of the lower file.
