Description

Domaine de l'inventionField of the invention

La présente invention concerne un brûleur à gaz double, notamment du type alimenté avec un gaz liquéfié et apte à être installé sur la bombonne contenant le gaz liquéfié, permettant, grâce à sa condition de doble brûleur, de fournir de la chaleur à des récipients, allant des récipients à petit diamètre, comme les pots et les cafetières, jusqu'aux récipients à plus grand diamètre, comme les casseroles et les poêles à paella, l'utilisation simultanée des deux brûleurs étant possible dans le cas des récipients à plus grands diamètres.The present invention relates to a dual gas burner, in particular of the type supplied with a liquefied gas and suitable for being installed on the tank containing the liquefied gas, making it possible, by virtue of its dual burner condition, to supply heat to containers, ranging from small diameter containers, such as pots and coffee makers, to larger diameter containers, such as casseroles and paella pans, with simultaneous use of both burners for larger diameter containers .

État de l'artState of the art

Les appareils de cuisine du type de ceux qui s'accouplent directement à l'embouchure d'une bombonne de gaz liquéfié présentent normalement un seul brûleur qui, généralement, est à diamètre réduit.Kitchen appliances of the type that mate directly to the mouth of a liquefied gas cylinder normally have a single burner which, generally, is reduced diameter.

Dans maintes occasions de la vie quotidienne, ces appareils résultent insuffisants pour cuisiner dans ceux-ci des récipients à dimensions supérieures à celle d'un pot, poêle, casserole, cocotte aux dimensions habituelles, étant donné que le foyer de chaleur se trouve centré et éloigné de la périphérie du récipient, comme il est le cas d'un poêle à paella, une rôtissoire, une grande marmite ou grande casserole, la chaleur devant été distribuée sur toute la surface du fond du récipient.On many occasions in everyday life, these appliances are insufficient to cook in them containers larger than a pot, pan, saucepan, casserole with the usual dimensions, since the heat source is centered and away from the periphery of the container, as is the case of a paella pan, a roasting pan, a large pot or large pan, the heat has been distributed over the entire surface of the bottom of the container.

Dans les cuisinières stables, dans lesquelles le gaz est fourni en provenance d'un réseau ou une bombonne au moyen d'une tubulure flexible ou rigide, il est habituel qu'un des brûleurs de celle-ci comporte deux ou plusieurs couronnes de feu, généralement simultanées, bien que dans quelques cas elles peuvent être indépendantes. A titre d'exemple, on peut citer les documents ES2110588T3 et ES2245970T3 .In stable stoves, in which the gas is supplied from a network or a tank by means of a flexible or rigid pipe, it is usual that one of the burners of the latter comprises two or more crowns of fire, usually simultaneous, although in some cases they may be independent. By way of example, mention may be made of the documents ES2110588T3 and ES2245970T3 .

Ces brûleurs sont en fonte métallique et, en général, ils ont un poids élevé qui les rend inaptes à être incorporés aux plaques de cuisson ou cuisinières du type de celles qui sont situées directement sur l'embouchure de la bombonne de gaz liquéfié.These burners are made of metal cast iron and, in general, they have a high weight that makes them unfit to be incorporated into the hobs or cookers of the type that are located directly on the mouth of the liquefied gas cylinder.

Sommaire de l'inventionSummary of the invention

Afin de faire possible la disponibilité d'un brûleur double dans un fourneau, plaque de cuisson ou cuisinière du type de ceux montés directement sur l'embouchure de la bombonne de gaz liquéfié, on a adopté la solution de construire un brûleur en une matière très légère pour le cas, comme la tôle métallique en acier.In order to make possible the availability of a double burner in a furnace, hob or cooker of the type mounted directly on the mouth of the liquefied gas cylinder, the solution of building a burner in a very light for the case, like steel sheet metal.

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

Une réalisation préférée du brûleur à gaz double qui constitue l'objet de la présente invention est celle représentée, dans son aspect externe, sur les Figures 1 et 2. On constate dans celles-ci que le brûleur à gaz double 1 est constitué par l'association d'un corps laminaire supérieur 2 de plan circulaire avec un corps laminaire inférieur 3, également de plan circulaire, qui conforment entre les deux une enceinte centrale 4 et un anneau périphérique tubulaire 5, lesquels présentent des orifices de flamme 6 qui sont situés, respectivement, sur les parois périphériques 7 et 8 de ladite enceinte centrale 4 dudit anneau périphérique tubulaire 5 et dans le sens centrifuge.A preferred embodiment of the dual gas burner which is the subject of the present invention is that represented, in its external aspect, on the Figures 1 and 2 . It can be seen in these that the double gas burner 1 is constituted by the combination of an upper laminar body 2 of circular plane with a lower laminar body 3, also of circular plane, which conform between the two a central chamber 4 and a tubular peripheral ring 5, which have flame orifices 6 which are located, respectively, on the peripheral walls 7 and 8 of said central chamber 4 of said tubular peripheral ring 5 and in the centrifugal direction.

Ladite enceinte centrale 4 et ledit anneau périphérique tubulaire 5, comme il est montré dans les Figures 3 et 4, reçoivent l'alimentation de gaz de la bombonne, une fois conditionnée la pression au moyen d'un détendeur 9, à travers une vanne de distribution 10 qui est pourvue d'une vanne tout-ou-rien 11 et qui envoie sélectivement et/ou simultanément le gaz à l'enceinte centrale 4, à travers une douille tronconique 12 à effet Venturi avec des orifices 13 pour la prise de comburant, et à l'anneau périphérique tubulaire 5, à travers une conduite radiale coudée 14 pourvue d'orifices 15 d'admission de comburant.Said central chamber 4 and said tubular peripheral ring 5, as shown in FIGS. Figures 3 and 4 , receive the gas supply of the canister, once the pressure is conditioned by means of a pressure reducer 9, through a distribution valve 10 which is provided with an on-off valve 11 and which selectively sends and / or simultaneously the gas to the central chamber 4, through a frustoconical socket 12 with Venturi effect with orifices 13 for the combustionant inlet, and to the tubular peripheral ring 5, through a bent radial duct 14 provided with orifices 15 of oxidizer inlet.

La Figure 5 montre la disposition des composants du brûleur double, dans laquelle l'ensemble formé par les corps laminaires supérieur 2 et inférieur 3 est supporté sur la vanne de distribution 10 à travers un godet 16 présentant sa convexité dirigée vers la vanne de distribution 10 pour constituer un siège sur celle-ci. Le godet 16 s'étend périmétralement par un collier 17 de siège pour ledit ensemble de corps laminaires supérieur 2 et inférieur 3 de plan circulaire. Le godet 16 présente en son centre un orifice 18 pour le positionnement d'une douille tronconique 12 et une série d'orifices 19 de passage d'air vers la surface supérieure dudit ensemble, à travers une ouverture annulaire 20 prévue entre l'enceinte centrale 4 et l'anneau périphérique tubulaire 5 dudit ensemble.The Figure 5 shows the arrangement of the components of the double burner, in which the assembly formed by the upper and lower laminar bodies 2 is supported on the dispensing valve 10 through a cup 16 having its convexity directed towards the dispensing valve 10 to constitute a seat on it. The bucket 16 extends perimetrically by a seat collar 17 for said set of upper laminar bodies 2 and 3 of circular plane. The bucket 16 has in its center an orifice 18 for the positioning of a frustoconical sleeve 12 and a series of orifices 19 for air passage to the upper surface of said assembly, through an annular opening 20 provided between the central chamber 4 and the tubular peripheral ring 5 of said assembly.

Sur les Figures 3, 4 et 5 on observe que la vanne de distribution 10 est constituée d'un corps qui par une partie inférieure présente des moyens 21 pour son accouplement à l'embouchure d'une bombonne de gaz liquéfié et d'une conduite 22 d'entrée du gaz combustible à la pression de la bombonne. La conduite 22 est contrôlée par la vanne tout-ou-rien 11 qui permet l'accès du gaz à pression au détendeur 9. Comme on peut observer sur la Figure 6, une fois conditionné à pression réduite dans le détendeur 9 le gaz est contenu dans une chambre à gaz 23 à pression conditionnée de laquelle partent deux conduites de sortie 24 et 25 vers deux vannes de passage 26 et 27 correspondantes qui contrôlent, à leur tour, le passage du débit de gaz conditionné vers le brûleur central constitué par l'enceinte centrale 4 et vers le brûleur périphérique constitué par l'anneau périphérique tubulaire 5. Dans les conduites de sortie 28 et 29 vers les brûleurs sont disposés les injecteurs correspondants 30 et 31.On the Figures 3, 4 and 5 it is observed that the dispensing valve 10 consists of a body which at a lower part has means 21 for coupling to the mouth of a tank of liquefied gas and a pipe 22 for entering the combustible gas. the pressure of the tank. The pipe 22 is controlled by the on-off valve 11 which allows access of the pressurized gas to the pressure reducer 9. As can be seen in FIG. Figure 6 when packaged under reduced pressure in the expander 9, the gas is contained in a gas chamber 23 with a pressurized pressure from which two outlet pipes 24 and 25 leave. to two corresponding passage valves 26 and 27 which in turn control the passage of the conditioned gas flow to the central burner constituted by the central chamber 4 and to the peripheral burner constituted by the tubular peripheral ring 5. outlet pipes 28 and 29 to the burners are arranged the corresponding injectors 30 and 31.

Sur la propre figure 5 on constate que la vanne tout-ou-rien 11 est constituée par un obturateur 32 qui passe de manière ajustée dans l'intérieur cylindrique d'un appendice tubulaire 33 du corps de la vanne de distribution 10, ledit obturateur 32 étant sollicité par un ressort qui l'applique de manière stable contre un siège de la conduite d'entrée de gaz 22 à ladite vanne à partir de la bombonne. La conduite 22 est située au fond 34 dudit appendice tubulaire 33 et se trouve en communication avec l'embouchure de sortie de la bombonne. Des moyens de levier 35 sont disposés pour vaincre le ressort et situer l'obturateur 32 dans une position stable d'ouverture. Dans ledit fond 34 le siège d'obturation est accompagné de l'orifice de sortie 36 du gaz vers le détendeur 9.On the own figure 5 it can be seen that the on-off valve 11 is constituted by a shutter 32 which passes neatly into the cylindrical interior of a tubular appendage 33 of the body of the dispensing valve 10, said shutter 32 being urged by a spring which stably applies against a seat of the gas inlet pipe 22 to said valve from the cylinder. The pipe 22 is located at the bottom 34 of said tubular appendix 33 and is in communication with the outlet mouth of the canister. Lever means 35 are provided to overcome the spring and locate the shutter 32 in a stable open position. In said bottom 34 the closure seat is accompanied by the outlet port 36 of the gas to the expander 9.

La Figure 5 illustre également le fait que les parois périphériques 7 et 8, respectivement, de l'enceinte centrale 4 et de l'anneau périphérique tubulaire 5 sont configurées selon des surfaces tronconiques.The Figure 5 also illustrates that the peripheral walls 7 and 8, respectively, of the central chamber 4 and the tubular peripheral ring 5 are configured in frustoconical surfaces.
