Description

La présente invention est relative à une amélioration dans le domaine des appareils de cuisson à gaz du type cuisinière ou plaque de cuisson comportant au moins un brûleur à gaz de type pot.The present invention relates to an improvement in the field of gas cooking appliances of the stove or hob type comprising at least one gas burner of the pot type.

Un brûleur pot est un ensemble comportant généralement un corps formant le pot sur le fond duquel est monté un injecteur relié à un conduit d'alimentation en gaz, et une couronne posée sur le bord supérieur du corps et munie d'un conduit central qui délimite avec le corps, une chambre de mélange gaz-air.A pot burner is an assembly generally comprising a body forming the pot on the bottom of which is mounted an injector connected to a gas supply duct, and a crown placed on the upper edge of the body and provided with a central duct which delimits with the body, a gas-air mixing chamber.

On connaît du document GB-2 256 268 un appareil de cuisson à gaz du type comportant une plaque d'âtre, au moins un brûleur du type brûleur pot comprenant un corps et une couronne posée sur le corps et munie d'un conduit central qui délimite avec le corps une chambre de mélange air-gaz. Par ailleurs, le corps est formé par emboutissage de la plaque d'âtre et présente un orifice inférieur pour le passage d'un injecteur d'axe longitudinal donné.Document GB-2 256 268 discloses a gas cooking appliance of the type comprising a hearth plate, at least one burner of the pot burner type comprising a body and a crown placed on the body and provided with a central duct which defines with the body an air-gas mixing chamber. Furthermore, the body is formed by stamping the hearth plate and has a lower orifice for the passage of an injector of given longitudinal axis.

Dans cet appareil cependant, le centrage du conduit central est réalisé par l'intermédiaire d'ailettes reposant sur le rebord du corps. Il en résulte que le conduit central est centré sur l'axe du corps.In this apparatus, however, the central duct is centered by fins resting on the edge of the body. As a result, the central duct is centered on the axis of the body.

Or, les études de la Demanderesse ont montré qu'un tel agencement pouvait nuire à la combustion car, en raison des tolérances dans le positionnement de l'orifice pour le passage de l'injecteur, l'axe de ce dernier ne coïncide pas toujours avec l'axe du corps. Le conduit central n'est alors pas centré par rapport à l'axe de l'injecteur.However, the Applicant's studies have shown that such an arrangement could harm combustion because, because of the tolerances in the positioning of the orifice for the passage of the injector, the axis of the latter does not always coincide with the axis of the body. The central duct is then not centered relative to the axis of the injector.

La présente invention a pour but de proposer un ensemble brûleur à moindre coût, facilement démontable en vue de son nettoyage ou en vue de permettre un accès facile à l'injecteur, et dont les performances en terme de combustion sont optimisées et reproductibles.The present invention aims to provide a burner assembly at low cost, easily removable for cleaning or to allow easy access to the injector, and whose performance in terms of combustion are optimized and reproducible.

Le but précédent est atteint selon l'invention grâce à un nouvel appareil de cuisson à gaz tel que défini dans la revendication 1. Dans un mode de réalisation préférentiel de l'invention, l'injecteur , maintenu par une partie tubulaire d'un porte-injecteur passant par l'orifice inférieur du corps selon ledit axe et fixée à ce corps par l'intermédiare d'une pièce formant écrou autour dudit axe longitudinal pour recevoir la partie tubulaire, et les moyens réalisant le centrage du conduit centrél comportent des ailettes de centrage prolongeant le conduit central de manière à venir en appui latéral contre la pièce formant écrou.The above object is achieved according to the invention thanks to a new gas cooking appliance as defined in claim 1. In a preferred embodiment of the invention, the injector, held by a tubular part of a door -injector passing through the lower orifice of the body along said axis and fixed to this body by the intermediary of a piece forming a nut around said longitudinal axis to receive the tubular part, and the means providing for centering of the central conduit comprise centering fins extending the central duct so as to come into lateral abutment against the part forming a nut.

Avantageusement, l'appareil peut comporter en outre un dispositif empêchant la rotation de la couronne autour de l'axe longitudinal de l'injecteur.Advantageously, the device can also include a device preventing rotation of the crown around the longitudinal axis of the injector.

L'invention et les avantages qu'elle procure seront mieux compris au vu de la description suivante, faite en référence à la figure unique annexée au présent texte :The invention and the advantages which it provides will be better understood in the light of the following description, given with reference to the single figure appended to this text:

Sur la figure, on a représenté une vue en coupe transversale d'une partie d'une plaque d'âtre 1 d'un appareil de cuisson selon un mode de réalisation préférentiel de l'invention.In the figure, there is shown a cross-sectional view of part of a hearth plate 1 of a cooking appliance according to a preferred embodiment of the invention.

La plaque d'âtre 1 est réalisée en tôle, par exemple en acier inoxydable. A titre d'exemple, elle présente une épaisseur comprise entre 0,8mm et 1,2mm. Habituellement, cette plaque d'âtre est emboutie pour réaliser un certain nombre de profils tels que les rebords externes de la plaque, non visibles sur la figure, ou des surélévations 2 formant des éléments-supports pour la couronne 3 du brûleur. Dans les plaques de l'art antérieur, la partie centrale entourée par les surélévations 2 est évidée pour former une ouverture pour le passage du corps du brûleur.The hearth plate 1 is made of sheet metal, for example of stainless steel. For example, it has a thickness of between 0.8mm and 1.2mm. Usually, this hearth plate is stamped to produce a certain number of profiles such as the outer edges of the plate, not visible in the figure, or raised areas 2 forming support elements for the crown 3 of the burner. In the plates of the prior art, the central part surrounded by the elevations 2 is hollowed out to form an opening for the passage of the burner body.

De manière différente, et selon une première caractéristique de l'invention, le corps 4 du brûleur est réalisé par emboutissage de la plaque d'âtre 1. L'embouti est réalisé en même temps que l'emboutissage du reste de la plaque. Il présente une forme cylindrique dans le mode de réalisation représenté, mais d'autres formes peuvent être envisagées. Le fond du corps 4 comporte un orifice inférieur 5 permettant le passage d'un injecteur de gaz 6 d'axe longitudinal XX'.In a different manner, and according to a first characteristic of the invention, the body 4 of the burner is produced by stamping the hearth plate 1. The stamping is produced at the same time as the stamping of the rest of the plate. It has a cylindrical shape in the embodiment shown, but other shapes can be envisaged. The bottom of the body 4 has a lower orifice 5 allowing the passage of a gas injector 6 with a longitudinal axis XX '.

La couronne 3 comporte un conduit central tubulaire 30, qui délimite avec le corps 4 une chambre 31 de mélange du gaz en provenance de l'injecteur 6 et de l'air primaire provenant de l'atmosphère ambiante, comme indiqué par la flèche F. Avantageusement, la couronne 3 est simplement posée sur le rebord supérieur du corps 4 grâce à des ailettes de positionnement 32 radiales venant en appui sur la plaque d'âtre. Ces ailettes de positionnement sont par exemple au nombre de quatre, et sont régulièrement espacées autour de l'axe de la couronne. Par ailleurs, elles surélèvent avantageusement la couronne par rapport à la plaque d'âtre de manière à permettre l'accès à la chambre de mélange 31 pour l'air primaire. Un chapeau de brûleur 9 est posé par ailleurs sur la couronne pour la répartition des flammes. Dans une autre variante, ce chapeau peut faire partie intégrante de la couronne.The crown 3 includes a central tubular conduit 30, which defines with the body 4 a chamber 31 for mixing the gas coming from the injector 6 and the primary air coming from the ambient atmosphere, as indicated by the arrow F. Advantageously, the crown 3 is simply placed on the upper edge of the body 4 by means of radial positioning fins 32 bearing on the hearth plate. These positioning fins are for example four in number, and are regularly spaced around the axis of the crown. They also advantageously raise the crown relative to the hearth plate so as to allow access to the mixing chamber 31 for the primary air. A burner cap 9 is also placed on the crown for the distribution of the flames. In another variant, this hat can be an integral part of the crown.

Selon une autre caractéristique importante de l'invention, l'appareil comporte des moyens permettant à la couronne 3 d'être toujours centrée sur l'axe longitudinal XX' de l'injecteur :According to another important characteristic of the invention, the device comprises means allowing the crown 3 to always be centered on the longitudinal axis XX 'of the injector:

Dans le mode de réalisation représenté, l'injecteur 6 est maintenu en position par la partie tubulaire 70 d'un porte-injecteur 7, lui-même relié au tuyau d'amenée du gaz.In the embodiment shown, the injector 6 is held in position by the tubular part 70 of an injector holder 7, itself connected to the gas supply pipe.

Cette partie tubulaire passe par l'orifice inférieur 5 du corps 4 selon l'axe XX', et présente une surface extérieure filetée apte à recevoir une pièce 8 formant écrou autour de l'axe longitudinal, et maintenant le porte-injecteur fixé au fond du corps du brûleur. Dans ces conditions, les moyens permettant le centrage de la couronne, ou plus exactement du conduit central 30 de la couronne, sur l'axe longitudinal XX' de l'injecteur, comportent des ailettes de centrage 33 qui prolongent le conduit central de façon à venir s'appuyer latéralement contre la pièce 8 formant écrou, comme le montre clairement la figure. Ces ailettes de centrage 33 sont régulièrement espacées autour de la pièce formant écrou de manière à laisser passer l'air primaire. Préférentiellement, elles sont au nombre de quatre, chaque ailette de positionnement 32 se situant dans le même plan qu'une ailette de centrage 33.This tubular part passes through the lower orifice 5 of the body 4 along the axis XX ', and has a threaded outer surface capable of receiving a part 8 forming a nut around the longitudinal axis, and maintaining the injector holder fixed to the bottom. of the burner body. Under these conditions, the means allowing the centering of the crown, or more precisely of the central duct 30 of the crown, on the longitudinal axis XX 'of the injector, comprise centering fins 33 which extend the central duct so as to come to bear laterally against the part 8 forming a nut, as clearly shown in the figure. These centering fins 33 are regularly spaced around the nut-forming part so as to allow the primary air to pass. Preferably, there are four of them, each positioning fin 32 lying in the same plane as a centering fin 33.

L'appareil de cuisson selon l'invention peut être encore amélioré par un dispositif empêchant la couronne 3 de tourner autour de l'axe longitudinal de l'injecteur :The cooking appliance according to the invention can be further improved by a device preventing the crown 3 from rotating around the longitudinal axis of the injector:

En effet, il est connu de prévoir que la couronne produise des flammes pilotes réparties tous les 90°, ces flammes pilotes étant des petites flammes qui doivent toujours être en regard des doigts de grille (non représentés) au-dessus du brûleur pour supporter les récipients.Indeed, it is known to provide that the crown produces pilot flames distributed every 90 °, these pilot flames being small flames which must always be opposite the grate fingers (not shown) above the burner to support the containers.

Comme représenté sur la figure, le dispositif anti-rotation est ici constitué par la bougie d'allumage 10 du brûleur qui s'étend sensiblement verticalement au-dessus de la plaque d'âtre. Cette bougie traverse une encoche prévue à la périphérie de la couronne, dont on ne voit sur la figure qu'une paroi 11. Avantageusement, la bougie d'allumage est portée par le porte-injecteur, et s'étend au-dessus de la plaque d'âtre au travers d'une ouverture 12 réalisée dans la plaque.As shown in the figure, the anti-rotation device is here constituted by the spark plug 10 of the burner which extends substantially vertically above the hearth plate. This candle crosses a notch provided at the periphery of the crown, which is not seen in the figure that a wall 11. Advantageously, the spark plug is carried by the injector holder, and extends above the hearth plate through an opening 12 made in the plate.

Comme on l'a représenté sur la figure, le porte-injecteur 7 peut comporter une partie 71 de forme similaire à la partie qui supporte la bougie d'allumage, servant par exemple au maintien d'un thermocouple de sécurité gaz (non représenté).As shown in the figure, the injector holder 7 may include a part 71 similar in shape to the part which supports the spark plug, for example for maintaining a gas safety thermocouple (not shown) .

Le porte-injecteur présente, par ailleurs, avantageusement deux pions 72 servant à indexer le porte-injecteur dans le carter (non représenté) de l'appareil.The injector holder moreover advantageously has two pins 72 serving to index the injector holder in the casing (not shown) of the device.

Les avantages de l'invention telle qu'elle vient d'être décrite sont multiples :The advantages of the invention as just described are manifold:

Tout d'abord, la fabrication du brûleur se voit considérablement simplifiée et moins coûteuse. En effet, le pot du brûleur faisant à présent partie intégrante de la plaque, on a éliminé toute pièce qui était nécessaire à l'insertion et à la fixation d'un corps de brûleur distinct de la plaque.First, the manufacture of the burner is considerably simplified and less costly. Indeed, the pot of the burner now forming an integral part of the plate, we have eliminated any part which was necessary for the insertion and fixing of a burner body separate from the plate.

Le nettoyage du brûleur se trouve également considérablement simplifié, ce qui présente un atout non négligeable pour les utilisateurs.Cleaning the burner is also considerably simplified, which is a significant advantage for users.

Par ailleurs, on peut avoir besoin de démonter et de changer l'injecteur, par exemple pour fonctionner avec différents gaz. Cette opération est très simple avec l'appareil conforme à l'invention car il suffit d'enlever la couronne pour avoir directement accès à l'injecteur. Il n'est donc plus nécessaire, comme dans le cas de brûleurs jusqu'ici connus, de démonter le corps du brûleur et le porte-injecteur.Furthermore, it may be necessary to dismantle and change the injector, for example to operate with different gases. This operation is very simple with the device according to the invention because it suffices to remove the crown to have direct access to the injector. It is therefore no longer necessary, as in the case of previously known burners, to disassemble the burner body and the injector holder.

En outre, le fait de réaliser le centrage de la couronne sur l'axe de l'injecteur permet d'optimiser les résultats gaziers. En effet, l'axe du conduit central se trouve toujours dans la direction du gaz, et ce malgré les tolérances dans le positionnement de l'ouverture 5 lors de la fabrication. Ce résultat ne pourrait être obtenu en centrant la couronne par rapport au corps du brûleur.In addition, the fact of centering the crown on the axis of the injector makes it possible to optimize the gas results. Indeed, the axis of the central conduit is always in the direction of the gas, and this despite the tolerances in the positioning of the opening 5 during manufacture. This result could not be obtained by centering the crown relative to the body of the burner.

Bien entendu, d'autres variantes de réalisation peuvent être envisagées sans sortir du cadre de l'invention :Of course, other alternative embodiments can be envisaged without departing from the scope of the invention:

On peut notamment envisager de fixer le porte-injecteur non par la pièce 8, mais par tout autre moyen, tel que des vis. Les ailettes de centrage sont alors conçues pour venir s'appuyer latéralement directement sur la partie tubulaire 70.One can in particular consider fixing the injector holder not by the part 8, but by any other means, such as screws. The fins of centering are then designed to come to bear laterally directly on the tubular part 70.

Par ailleurs, tous les brûleurs ne sont pas forcément équipés d'un allumage intégré. La bougie d'allumage est alors remplacée par un pion factice permettant l'anti-rotation de la couronne.In addition, not all burners are necessarily equipped with an integrated ignition. The spark plug is then replaced by a dummy pin allowing the anti-rotation of the crown.
