Abstract
Description
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.
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.
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.
