L'invention a donc pour but de proposer un brĆ»leur Ć  gaz Ć  multiples couronnes de flammes d'un type amĆ©liorĆ©, dont la structure soit propre Ć  confĆ©rer un niveau de sĆ©curitĆ© moderne tout en restant de fabrication simple avec un nombre de piĆØces composantes rĆ©duit Ć  un minimum, et au surplus avec un dĆ©veloppement vertical relativement rĆ©duit autorisant sa mise en place aussi bien sur une cuisiniĆØre conventionnelle que sur une plaque de cuisson.The invention therefore aims to provide a burner with multiple flame crowns of an improved type, whose structure is suitable to confer a level of modern security while remaining simple to manufacture with a number of component parts reduced to a minimum, and in addition with a relatively vertical development reduced allowing its installation as well on a conventional stove only on a hob.

For these purposes, a burner as mentioned in the preamble, being arranged in accordance with the invention, is characterized in that it comprises:
  • a burner body suitable for being fixed to the top plate, on the bottom thereof, and comprising:
    • a first gas inlet and, in communication with it, a first gas injector having its axis directed upwards,
    • a second gas inlet and, in communication with it, a second gas injector with a substantially horizontal axis and situated opposite a convergent-divergent duct forming a Venturi which extends over at least most of the transverse extent of the burner body, said duct being, at its end opposite to the second injector, in communication with a substantially vertical well open upwards;
  • an external burner head supported, by support means engaged through a cut-out of said top plate, by said burner body, said burner head comprising:
    • a substantially annular chamber bordered at least monolaterally by flame passages and having at its bottom an opening situated opposite the above-mentioned substantially vertical well of the burner body,
    • a central region having a vertical central recess, and
    • lights located between the said annular chamber and said central region,
    • the aforesaid means for supporting the external burner head being configured so that said burner head is situated above and at a distance from the top plate by providing therewith an annular space surrounding said central region, said support means having lateral recesses connecting said central recess of the central region and said annular space;
  • an internal burner head capable of being supported centrally by the aforesaid external burner head opposite the aforesaid central recess of the central region, said internal burner head comprising a central well directed coaxially to the axis of the above first gas injector.

GrĆ¢ce Ć  la structure adoptĆ©e, on constitue un brĆ»leur Ć  multiples couronnes de flammes dans lequel la totalitĆ© de l'air primaire nĆ©cessaire au fonctionnement du premier brĆ»leur, central, et du second brĆ»leur, annulaire, est amenĆ©e respectivement au voisinage des premier et second injecteurs de gaz par des trajets situĆ©s exclusivement au-dessus de la plaque de dessus de l'appareil de cuisson ; Ć  cet effet, l'air primaire pĆ©nĆØtre dans l'espace annulaire dĆ©fini entre la tĆŖte de brĆ»leur extĆ©rieur et la plaque de dessus, traverse les Ć©videments latĆ©raux des moyens de support de la tĆŖte de brĆ»leur extĆ©rieur et pĆ©nĆØtre dans le corps de brĆ»leur oĆ¹ il est mĆ©langĆ© avec le jet de gaz sortant du premier injecteur alimentant le brĆ»leur central, tandis que par ailleurs il passe dudit espace annulaire prĆ©citĆ© directement, par une ouverture latĆ©rale prĆ©vue Ć  cet effet, vers l'entrĆ©e du conduit convergent-divergent horizontal oĆ¹ il est mĆ©langĆ© au jet de gaz sortant du second injecteur pour l'alimentation du brĆ»leur extĆ©rieur.Thanks to the structure adopted, a multiple flame crown burner in which the all of the primary air required to operate the first burner, central, and second burner, annular, is brought respectively to the vicinity of the first and second gas injectors via paths located exclusively above the top plate of the appliance cooking; for this purpose, the primary air enters the annular space defined between the burner head outside and the top plate, cross the recesses side of the burner head support means outside and enters the burner body where it is mixed with the gas jet leaving the first injector feeding the central burner, while otherwise passes from said annular space directly above, by a side opening provided for this purpose, towards the entrance of the horizontal convergent-divergent duct where it is mixed with the gas jet leaving the second injector to the external burner supply.

De mĆŖme, la totalitĆ© de l'air secondaire qui vient alimenter les flammes arrive par le dessus de la plaque de dessus ; cet air secondaire est constituĆ© pour partie par l'air ambiant entourant les brĆ»leurs (couronne de flammes extĆ©rieure du second brĆ»leur, annulaire ; couronne de flammes du premier brĆ»leur, central), soit pour partie par une fraction de l'air pĆ©nĆ©trant dans l'espace annulaire dĆ©fini par la tĆŖte de brĆ»leur extĆ©rieur et la plaque de dessus, cette fraction d'air passant, Ć  travers les lumiĆØres prĆ©citĆ©es, entre les deux brĆ»leurs central et annulaire et alimentant les flammes de la couronne intĆ©rieure du brĆ»leur annulaire et, pour partie, les flammes du brĆ»leur central.Likewise, all of the secondary air that comes feeding the flames arrives from the top of the plate above ; this secondary air is partly constituted by the ambient air surrounding the burners (crown of flames outside of the second burner, annular; crown of first burner, central), partly by a fraction of the air entering the annular space defined by the external burner head and the plate above, this fraction of air passing through the aforementioned lights, between the two central burners and annular and feeding the crown flames inside of the annular burner and, in part, the central burner flames.

On agence ainsi le brĆ»leur Ć  multiples couronnes de flammes avec des dispositions structurelles propres Ć  procurer une alimentation en air, primaire et secondaire, conduisant Ć  empĆŖcher une rĆ©percussion des utilisations des parties sous-jacentes de l'appareil de cuisson sur les flammes, mĆŖme Ć  petit rĆ©gime, autrement dit Ć  empĆŖcher une Ć©ventuelle extinction des flammes, notamment Ć  faible rĆ©gime, lors d'une fermeture violente de la porte d'un four sous-jacent notamment.We thus arrange the burner with multiple crowns of flames with structural arrangements specific to provide air supply, primary and secondary, leading to preventing a repercussion of uses underlying parts of the cooking appliance on the flames, even at low speed, in other words to prevent a possible flame extinction, especially at low regime, during a violent closing of the door of a including the underlying oven.

En outre, l'agencement du Venturi horizontal pour l'alimentation de la tĆŖte de brĆ»leur extĆ©rieur et du Venturi dirigĆ© vers le haut et constituĆ©, comme indiquĆ© plus loin, pour partie tubulairement et pour partie radialement horizontalement, permet d'obtenir un brĆ»leur de hauteur relativement faible propre Ć  ĆŖtre montĆ© aussi bien sur une cuisiniĆØre que sur une plaque de cuisson.In addition, the horizontal Venturi arrangement for the supply of the external burner head and the Venturi directed upwards and formed, as shown further on, partly tubularly and partly radially horizontally, provides a burner of relatively low height suitable for mounting also well on a stove than on a hob.

Dans un premier mode de rĆ©alisation possible, qui prĆ©sente l'avantage de la simplicitĆ©, le puits central de la tĆŖte de brĆ»leur intĆ©rieur est dirigĆ© sensiblement verticalement et l'axe du premier injecteur est sensiblement vertical.In a first possible embodiment, which has the advantage of simplicity, the central well of the interior burner head is directed substantially vertically and the axis of the first injector is substantially vertical.

Toutefois, dans un autre mode de rĆ©alisation, intĆ©ressant car il conduit Ć  un sensible allongement du Venturi et donc Ć  une meilleure efficacitĆ© du mĆ©lange air-gaz, on prĆ©voit que le puits central de la tĆŖte de brĆ»leur intĆ©rieur et le premier injecteur qui lui est sensiblement coaxial soient inclinĆ©s d'environ 15 Ć  20Ā° par rapport Ć  la verticale.However, in another embodiment, interesting because it leads to a significant elongation of the Venturi and therefore a better efficiency of the air-gas mixture, the central well of the burner head is expected interior and the first injector which is substantially thereto coaxial are inclined by about 15 to 20 Ā° relative to the vertical.

Dans un exemple de rĆ©alisation d'emploi courant dans les appareils de cuisson mĆ©nagers, il est prĆ©vu que le brĆ»leur Ć  gaz comporte une seule chambre annulaire dans la tĆŖte de brĆ»leur extĆ©rieur, qui est bordĆ©e bilatĆ©ralement par des passages de flammes, et que le second brĆ»leur, annulaire, possĆØde deux couronnes de flammes, le brĆ»leur Ć©tant du type Ć  trois couronnes de flammes.In an example of realization of current job in household cooking appliances, it is expected that the gas burner has a single annular chamber in the external burner head, which is bordered bilaterally by passages of flame, and that the second burner, annular, has two crowns of flame, the burner being of the three flame crown type.

Dans une rĆ©alisation structurellement simple qui permet de constituer un nombre rĆ©duit de piĆØces propres Ć  ĆŖtre fabriquĆ©es en fonderie, les moyens de support de la tĆŖte de brĆ»leur extĆ©rieur sont solidaires de ladite tĆŖte de brĆ»leur extĆ©rieur et sont constituĆ©s sous la forme gĆ©nĆ©rale d'une jupe saillant infĆ©rieurement sous le dessous de ladite tĆŖte et d'un Ć©paulement entourant l'Ć©videment central de la rĆ©gion centrale de ladite tĆŖte de brĆ»leur. Avec le mĆŖme souci, la chambre annulaire de la tĆŖte de brĆ»leur extĆ©rieur peut ĆŖtre fermĆ©e, supĆ©rieurement, par un couvercle annulaire amovible posĆ© sur les parois latĆ©rales de la chambre. In a structurally simple realization which allows a reduced number of parts specific to be manufactured in a foundry, the support means of the external burner head are integral with said head of external burner and are constituted in the form general of a skirt projecting below under the below said head and a surrounding shoulder the central recess of the central region of said head burner. With the same concern, the annular chamber of the external burner head can be closed, top, by a removable annular cover placed on the side walls of the room.

De mĆŖme, il est intĆ©ressant, pour que le premier brĆ»leur, central, soit muni d'un Venturi de longueur suffisante, que le puits central de la tĆŖte de brĆ»leur intĆ©rieur prĆ©sente une section dĆ©croissante en direction du haut, formant ainsi un premier tronƧon de Venturi, tubulaire, et que la surface supĆ©rieure de la tĆŖte de brĆ»leur intĆ©rieur entourant l'orifice supĆ©rieur du puits central dĆ©finisse, conjointement avec un couvercle amovible la surmontant, un divergent annulaire radial formant un second tronƧon de Venturi, annulaire radial.Likewise, it is interesting that the first burner, central, either with a long Venturi sufficient, that the central well of the burner head interior has a decreasing section in direction from the top, thus forming a first section of Venturi, tubular, and that the upper surface of the head interior burner surrounding the upper orifice of the well central define, together with a cover removable above it, a radial annular divergent forming a second section of Venturi, annular radial.

Dans un mode de rĆ©alisation intĆ©ressant en ce qu'il permet une adaptation aisĆ©e du brĆ»leur aux exigences commerciales de vente des appareils de cuisson, on peut faire en sorte que la tĆŖte de brĆ»leur extĆ©rieur soit entourĆ©e infĆ©rieurement d'une jupe pĆ©riphĆ©rique inclinĆ©e vers le bas et que ladite jupe pĆ©riphĆ©rique soit constituĆ©e sous forme d'une piĆØce amovible.In an interesting embodiment in that that it allows an easy adaptation of the burner to the requirements sales of cooking appliances, we can ensuring that the exterior burner head is surrounded at the bottom by an inclined peripheral skirt down and that said peripheral skirt is formed as a removable part.

De plus, afin de ne pas multiplier les accessoires nƩcessaires au fonctionnement du brƻleur et de rƩduire ainsi le coƻt global du brƻleur, le brƻleur comporte un thermocouple de dƩtection de prƩsence de flammes et/ou un organe d'allumage Ʃlectrique et ledit thermocouple et/ou organe d'allumage sont fonctionnellement associƩs au brƻleur central.In addition, so as not to multiply the accessories necessary to operate the burner and reduce thus the overall cost of the burner, the burner has a flame detection thermocouple and / or a electric ignition member and said thermocouple and / or ignition device are functionally associated with central burner.

Un brĆ»leur agencĆ© conformĆ©ment Ć  l'invention prĆ©sente, grĆ¢ce Ć  sa structure, une grande souplesse d'implantation selon le type d'appareil de cuisson Ć  Ć©quiper. D'une part, la tĆŖte de brĆ»leur extĆ©rieur peut, selon les cas, ĆŖtre pourvue d'une seule couronne de flammes disposĆ©e soit intĆ©rieurement, soit extĆ©rieurement ou bien ĆŖtre pourvue de deux couronnes de flammes intĆ©rieure et extĆ©rieure. D'autre part, les brĆ»leurs central et extĆ©rieur peuvent, selon les cas, soit ĆŖtre raccordĆ©s Ć  une commande commune d'alimentation en gaz, soit ĆŖtre raccordĆ©s chacun Ć  une commande individuelle d'alimentation en gaz, ce qui autorise une modulation souple des conditions de chauffage en emplacement et dans le temps.A burner arranged in accordance with the invention presents, thanks to its structure, a great flexibility according to the type of cooking appliance to equip. On the one hand, the external burner head can, depending on the case, be provided with a single crown of flames arranged either internally or externally or be provided with two flame crowns indoor and outdoor. On the other hand, the burners central and exterior can, depending on the case, either be connected to a common gas supply control, either be connected each to an individual control gas supply, which allows modulation flexible heating conditions in location and in time.

En se reportant tout d'abord Ć  la figure 1, le brĆ»leur Ć  gaz de l'invention comporte une tĆŖte de brĆ»leur intĆ©rieur 1, qui est en position centrale, possĆ©dant une couronne de flammes pĆ©riphĆ©rique (passages de flammes 2) et au moins une tĆŖte de brĆ»leur extĆ©rieur 3, qui est annulaire et entoure Ć  distance la tĆŖte de brĆ»leur central 1, possĆ©dant au moins une couronne de flammes, intĆ©rieure et/ou extĆ©rieure. Dans l'exemple illustrĆ© dans l'ensemble des figures, la tĆŖte de brĆ»leur extĆ©rieur, annulaire, 3 possĆØde deux couronnes de flammes, l'une intĆ©rieure (passages de flammes 4) et l'autre extĆ©rieure (passages de flammes 5).Referring first to Figure 1, the gas burner of the invention has a burner head interior 1, which is in the central position, having a peripheral flame crown (flame passages 2) and at least one external burner head 3, which is annular and remotely surrounds the central burner head 1, having at least one inner ring of flames and / or outdoor. In the example illustrated overall figures, the external burner head, annular, 3 has two flame crowns, one inside (flame passages 4) and the other exterior (passages of flames 5).

Le brĆ»leur comporte en outre un corps de brĆ»leur 6 visible partiellement aux figures 1 et 2 et montrĆ© isolĆ©ment Ć  la figure 3. Ce corps de brĆ»leur 6 prĆ©sente ici une forme relativement allongĆ©e, sensiblement en correspondance avec le diamĆØtre de la tĆŖte de brĆ»leur extĆ©rieur 3 qui surmonte ledit corps.The burner further includes a burner body 6 partially visible in Figures 1 and 2 and shown in isolation in FIG. 3. This burner body 6 has here a relatively elongated shape, substantially in correspondence with the diameter of the burner head exterior 3 which overcomes said body.

Le corps de brĆ»leur 6 est agencĆ© pour ĆŖtre fixĆ©, par des moyens de fixation 7, sous la plaque de dessus d'un appareil de cuisson, tel qu'une cuisiniĆØre, laquelle plaque de dessus P est visible sur les dessins en coupe des figures 5, 6 et 7.The burner body 6 is designed to be fixed, by fixing means 7, under the top plate a cooking appliance, such as a stove, which top plate P is visible on the sectional drawings Figures 5, 6 and 7.

A une extrĆ©mitĆ© du corps de brĆ»leur 6 se trouve une premiĆØre arrivĆ©e de gaz 8, raccordable Ć  une alimentation en gaz via des moyens de contrĆ“le (non montrĆ©s) qui de prĆ©fĆ©rence lui sont propres.At one end of the burner body 6 is a first gas inlet 8, connectable to a gas supply via control means (not shown) which are preferably their own.

Comme on le voit Ć  la figure 5, l'arrivĆ©e de gaz 8 est en communication avec un injecteur de gaz 9 situĆ© coaxialement en regard d'une extrĆ©mitĆ© d'un conduit 10 d'abord convergent, puis divergent et formant Venturi tubulaire, qui s'Ć©tend sensiblement sur la plus grande partie de la longueur du corps de brĆ»leur 6, c'est-Ć -dire du diamĆØtre de la tĆŖte de brĆ»leur extĆ©rieur 3. Entre l'injecteur de gaz 9 et le conduit 10 se trouve une lumiĆØre 11 d'admission d'air primaire. A son extrĆ©mitĆ© terminale, le conduit 10 est en liaison avec un puits sensiblement vertical 12 amenant le mĆ©lange air-gaz dans la tĆŖte de brĆ»leur extĆ©rieur annulaire 3.As seen in Figure 5, the gas supply 8 is in communication with a gas injector 9 located coaxially opposite one end of a conduit 10 first converge, then diverge and form Venturi tubular, which extends substantially over the largest part of the length of the burner body 6, i.e. the diameter of the outer burner head 3. Between the gas injector 9 and the conduit 10 is a light 11 for primary air intake. At its end terminal, line 10 is connected to a well substantially vertical 12 bringing the air-gas mixture into the external annular burner head 3.

Comme visible plus facilement aux figures 4 et 6, le corps de brĆ»leur comporte une seconde arrivĆ©e de gaz 13 distincte de la premiĆØre arrivĆ©e 8 prĆ©citĆ©e, et disposĆ©e, ici, sur le cĆ“tĆ© du corps 6. L'arrivĆ©e de gaz 13 est raccordable Ć  une alimentation en gaz via des moyens de contrĆ“le (non montrĆ©s) qui de prĆ©fĆ©rence lui sont propres et sont distincts des moyens de contrĆ“le d'alimentation de la premiĆØre arrivĆ©e de gaz 8.As can be seen more easily in Figures 4 and 6, the burner body has a second gas inlet 13 distinct from the aforementioned first arrival 8, and arranged, here on the side of the body 6. The gas inlet 13 is connectable to a gas supply via means of controls (not shown) which are specific to it and are separate from the power control means of the first gas supply 8.

L'arrivĆ©e de gaz 13 est en communication avec un injecteur de gaz 14 qui est dirigĆ© vers le haut : Ć  la figure 6, l'axe de l'injecteur 14 est sensiblement vertical et sensiblement coaxial aux tĆŖtes de brĆ»leur intĆ©rieur 1 et extĆ©rieur 3.The gas inlet 13 is in communication with a gas injector 14 which is directed upwards: at the Figure 6, the axis of the injector 14 is substantially vertical and substantially coaxial with the burner heads inside 1 and outside 3.

Comme on le voit mieux Ć  la figure 4, le corps de brĆ»leur 5 supporte des accessoires nĆ©cessaires au fonctionnement sĆ©curisĆ© du brĆ»leur, et notamment au moins un thermocouple Th et au moins un organe d'allumage Ć©lectrique Aā„“.As best seen in Figure 4, the body of burner 5 supports accessories necessary for safe operation of the burner, and in particular at least a thermocouple Th and at least one ignition member electric Aā„“.

La tĆŖte de brĆ»leur extĆ©rieur 3 repose, Ć  travers une dĆ©coupe 30 pratiquĆ©e dans la plaque de dessus P, sur le corps de brĆ»leur 6 par l'intermĆ©diaire de moyens de support. A cet effet, on peut prĆ©voir, comme on le voit mieux aux figures 4 et 6, que le corps de brĆ»leur 6 prĆ©sente une collerette de support 16 globalement circulaire situĆ©e centralement et coaxialement Ć  l'injecteur vertical 14. Cette collerette 16 forme avec le fond central du corps de brĆ»leur 6 une sorte de cuve, ayant l'injecteur 14 en son centre et les moyens de support de la tĆŖte de brĆ»leur extĆ©rieur disposĆ©s latĆ©ralement. Dans l'exemple illustrĆ©, les moyens de support sont solidaires du dessous de la tĆŖte de brĆ»leur extĆ©rieur 3 et sont constituĆ©s sous forme d'une jupe 17 saillant vers le bas en formant extĆ©rieurement un Ć©paulement pĆ©riphĆ©rique 18 prenant appui sur le haut de la collerette 16 prĆ©citĆ©e. Cette jupe 17 est rĆ©alisĆ©e soit de faƧon continue avec des lumiĆØres, soit de faƧon discontinue (cas illustrĆ© Ć  la figure 6) afin de constituer des passages 20 pour l'air primaire comme cela apparaĆ­tra plus loin.The external burner head 3 rests, through a cutout 30 made in the top plate P, on the burner body 6 by means of support. To this end, we can plan, as we can see better in FIGS. 4 and 6, than the burner body 6 has a support flange 16 overall circular located centrally and coaxially to the vertical injector 14. This flange 16 forms with the central bottom of the burner body 6 a kind of tank, having the injector 14 in its center and the means of outside burner head support arranged laterally. In the example illustrated, the means of support are secured to the underside of the burner head outside 3 and are formed in the form of a skirt 17 protruding downwards outwardly forming a peripheral shoulder 18 bearing on the top of the flange 16 above. This skirt 17 is made either of continuously with lights, either so discontinuous (case illustrated in Figure 6) in order to build 20 primary air passages like this will appear later.

On notera en outre que le bord infĆ©rieur de la jupe 17 est conformĆ© pour coopĆ©rer avec des saillies 19 prĆ©vues dans le fond de la cuve, de faƧon Ć  bloquer en rotation la tĆŖte de brĆ»leur extĆ©rieur 3 sur le corps de brĆ»leur 6 et Ć  servir simultanĆ©ment Ć  les positionner mutuellement angulairement de faƧon correcte.Note also that the lower edge of the skirt 17 is shaped to cooperate with projections 19 provided in the bottom of the tank, so as to block in rotation of the external burner head 3 on the body of burner 6 and serve simultaneously to position them mutually angularly correctly.

Comme cela se voit mieux aux figures 4 et 5, la partie de la tĆŖte de brĆ»leur extĆ©rieur 3 qui entoure la rĆ©gion centrale munie de la jupe saillante 17 surplombe la plaque de dessus P en Ć©tant maintenue Ć  distance au-dessus de celle-ci, de sorte que la plaque de dessus P et la face infĆ©rieure de la tĆŖte de brĆ»leur 3 dĆ©finissent entre elles un espace annulaire 21, de forme irrĆ©guliĆØre eu Ć©gard Ć  la conformation gĆ©nĆ©rale du brĆ»leur. Les passages 20 prĆ©citĆ©s communiquent avec cet espace 21.As is best seen in Figures 4 and 5, the part of the external burner head 3 which surrounds the central region provided with the projecting skirt 17 overhangs the top plate P while being kept at a distance above of it, so the top plate P and the face bottom of burner head 3 define them an annular space 21, of irregular shape having regard to the general conformation of the burner. The aforementioned passages 20 communicate with this space 21.

La tĆŖte de brĆ»leur extĆ©rieur 3 comporte une chambre annulaire 22 situĆ©e au voisinage de la pĆ©riphĆ©rie externe de cette tĆŖte. La chambre 22 est formĆ©e par un canal dĆ©fini par un fond 23 et deux parois latĆ©rales concentriques 24, 25 et par un couvercle ou chapeau annulaire 26 coiffant ledit canal. Dans au moins une des parois 24, 25 sont pratiquĆ©es des encoches formant des passages de flammes. Dans l'exemple illustrĆ©, les deux parois 24, 25 sont munies d'encoches respectives 4, 5, de sorte que la tĆŖte de brĆ»leur extĆ©rieur comporte une double couronne de flammes.The external burner head 3 has a annular chamber 22 located near the periphery external of this head. Chamber 22 is formed by a channel defined by a bottom 23 and two side walls concentric 24, 25 and by a cover or cap annular 26 covering said channel. In at least one of walls 24, 25 are formed notches forming flames. In the example shown, the two walls 24, 25 are provided with respective notches 4, 5, so that the outer burner head has a double crown of flames.

L'ensemble de cet agencement est Ć©galement bien visible aux figures 2 et 3.The whole arrangement is also good visible in Figures 2 and 3.

Comme visible aux figures 2 et 6, le fond 23 prƩsente une ouverture 27 en regard du puits sensiblement vertical 11 prƩcitƩ.As shown in Figures 2 and 6, the bottom 23 has an opening 27 facing the well substantially vertical 11 above.

Comme visible aux figures 1, 2 et 6 notamment, le chapeau annulaire 26 est guidĆ©, lors de sa mise en place, et retenu en position par des doigts de positionnement 28 solidaires de la tĆŖte de brĆ»leur extĆ©rieur 3.As shown in Figures 1, 2 and 6 in particular, the annular cap 26 is guided during its installation, and held in position by positioning fingers 28 integral with the external burner head 3.

Comme visible aux figures 3 et 5, la tĆŖte de brĆ»leur extĆ©rieur 3 est agencĆ©e de sorte qu'entre une rĆ©gion centrale dont il sera question plus loin et la chambre annulaire 22, elle comporte des lumiĆØres 29 qui ajourent cette zone annulaire intermĆ©diaire, dans le but de permettre une circulation d'air comme cela apparaĆ­tra plus loin.As shown in Figures 3 and 5, the head of external burner 3 is arranged so that between a central region which will be discussed below and the annular chamber 22, it has lights 29 which open this intermediate annular zone, for the purpose to allow air circulation as it will appear further.

Enfin, la rĆ©gion centrale 31 de la tĆŖte de brĆ»leur extĆ©rieur 3 prĆ©sente un Ć©videment sensiblement vertical 32, coaxial Ć  l'axe de l'injecteur 14.Finally, the central region 31 of the burner head outer 3 has a substantially vertical recess 32, coaxial with the axis of the injector 14.

La tĆŖte de brĆ»leur central 1 prend appui pĆ©riphĆ©riquement sur un Ć©paulement annulaire 33 pratiquĆ© dans la tĆŖte de brĆ»leur extĆ©rieur 3. Sa rĆ©gion centrale, saillant vers le bas, est engagĆ©e dans l'Ć©videment 32 prĆ©citĆ© de la tĆŖte de brĆ»leur extĆ©rieur et prĆ©sente un puits central 34 coaxial Ć  l'axe de l'injecteur 14. Le puits 34 a une section dĆ©croissante vers le haut et forme un convergent.The central burner head 1 is supported peripherally on an annular shoulder 33 practiced in the external burner head 3. Its central region, projecting downwards, is engaged in the recess 32 above of the external burner head and has a central well 34 coaxial with the axis of the injector 14. The well 34 has a decreasing upward section and forms a convergent.

La paroi pĆ©riphĆ©rique 35 de la tĆŖte de brĆ»leur central 1 est percĆ©e d'Ć©chancrures 2 formant des passages de flammes. Un chapeau ou couvercle 36 repose sur la paroi 35. The peripheral wall 35 of the burner head central 1 is pierced with notches 2 forming passages of flames. A cap or cover 36 rests on the wall 35.

Les faces en regard du couvercle 36 et de la rĆ©gion centrale de la tĆŖte de brĆ»leur central 1 qui entoure l'orifice du puits 34 s'Ć©cartent sensiblement l'une de l'autre radialement vers l'extĆ©rieur, formant un divergent annulaire radial 37. L'ensemble du convergent tubulaire 34 et du divergent annulaire radial 37 constitue un Venturi.The facing faces of the cover 36 and the central region of the central burner head 1 which surrounds the orifice of the well 34 deviate substantially from each other radially outward, forming a radial annular divergent 37. The entire convergent tubular 34 and radial annular divergent 37 constitutes a Venturi.

A la figure 7 est reprĆ©sentĆ©e une variante de rĆ©alisation de l'agencement illustrĆ© Ć  la figure 6 et dans laquelle le puits central 34 et l'injecteur 14, coaxiaux, ne sont plus verticaux, mais inclinĆ©s d'un angle de 15 Ć  20Ā° par rapport Ć  la verticale. Cet agencement est prĆ©fĆ©rĆ© au montage d'axe vertical de la figure 6, en raison de l'allongement procurĆ© pour le puits 34 : bien que faible, cet allongement suffit Ć  amĆ©liorer le rendement du brĆ»leur central 1.In Figure 7 is shown a variant of realization of the arrangement illustrated in FIG. 6 and in which the central well 34 and the injector 14, coaxial, are no longer vertical, but tilted at an angle of 15 to 20 Ā° from the vertical. This arrangement is preferred in the vertical axis assembly of Figure 6, due to the elongation provided for well 34: although low, this extension is sufficient to improve the efficiency of the burner central 1.

Enfin, on notera que la tĆŖte de brĆ»leur extĆ©rieur 3 est, comme cela est souvent le cas pour les brĆ»leurs Ć  gaz, bordĆ©e infĆ©rieurement par une jupe annulaire pĆ©riphĆ©rique 38 inclinĆ©e vers le bas. Cette jupe peut ĆŖtre partie intĆ©grante de la tĆŖte de brĆ»leur 3 comme visible notamment aux figures 5, 6 et 7, ou bien peut ĆŖtre une piĆØce annulaire 39 rapportĆ©e de faƧon amovible sur la tĆŖte de brĆ»leur 3 : cette piĆØce annulaire 39 peut ĆŖtre mise en place grĆ¢ce Ć  des Ć©paulements appropriĆ©s comme illustrĆ©, en reprĆ©sentation partielle en coupe, Ć  la figure 8. En outre, il devient alors aisĆ© de conformer et/ou de dĆ©corer cette piĆØce annulaire de faƧon diverse afin de satisfaire par exemple les exigences commerciales.Finally, note that the external burner head 3 is, as is often the case for burners with gas, bordered below by an annular skirt device 38 inclined downwards. This skirt can be integral part of burner head 3 as visible in particular in FIGS. 5, 6 and 7, or else may be a annular part 39 removably attached to the head burner 3: this annular part 39 can be put in place thanks to appropriate shoulders as illustrated, in partial sectional representation, in Figure 8. In in addition, it then becomes easy to conform and / or decorate this annular part in various ways in order to satisfy for example business requirements.

Les dispositions structurelles qui viennent d'ĆŖtre dĆ©crites conduisent Ć  un brĆ»leur Ć  gaz Ć  multiples couronnes de flammes dans lequel la totalitĆ© de l'air, primaire et secondaire, nĆ©cessaire Ć  son fonctionnement lui est fournie par le dessus de la plaque de dessus P, ce qui Ć©vite les inconvĆ©nients (possibilitĆ© de soufflage de flammes) inhĆ©rents Ć  une alimentation partielle ou totale de l'air primaire par le dessous de la plaque P.The structural arrangements which have just been described lead to a multiple gas burner crowns of flame in which all of the air, primary and secondary, necessary for its operation is provided to it by the top of the top plate P, this which avoids the disadvantages (possibility of blowing flames) inherent in a partial or total diet primary air from below the plate P.

Sur les figures en coupe 5, 6 et 7, on a schĆ©matisĆ© par les flĆØches pleines F le trajet suivi par l'air primaire qui, depuis l'espace annulaire 21, parvient Ć  l'entrĆ©e du conduit 10 (figure 5) et simultanĆ©ment, traversant les ouvertures 20, parvient au niveau de l'injecteur 14 (figures 6 et 7).In the sectional figures 5, 6 and 7, we have diagrammed by the solid arrows F the path followed by the primary air which, from the annular space 21, reaches at the inlet of the conduit 10 (FIG. 5) and simultaneously, passing through the openings 20, reaches the level of the injector 14 (Figures 6 and 7).

Quant Ć  l'air secondaire qui doit parvenir aux pieds des flammes, ses trajets sont schĆ©matisĆ©s par les flĆØches en tirets f. Il provient pour partie de l'extĆ©rieur du brĆ»leur (flĆØches f1) pour la couronne de flammes externes, et d'une fraction de l'air en provenance de l'espace annulaire 21 et remontant Ć  travers les lumiĆØres 29 (flĆØches f2) et d'air extĆ©rieur arrivant par le dessus (flĆØches f3) pour les deux couronnes de flammes intĆ©rieures en vis-Ć -vis.As for the secondary air which must reach the feet of the flames, its paths are shown diagrammatically by the arrows in dashes f. It partly comes from the outside of the burner (arrows f 1 ) for the ring of external flames, and from a fraction of the air coming from the annular space 21 and rising through the lights 29 (arrows f 2 ) and outside air coming in from above (arrows f 3 ) for the two facing inner flame rings.

On notera enfin que, pour simplifier la structure du brĆ»leur et rĆ©duire son coĆ»t, on prĆ©voit un seul thermocouple Th et/ou un seul organe d'allumage Ć©lectrique Aā„“ qui sont alors associĆ©s fonctionnement au seul brĆ»leur central.Finally, note that, to simplify the structure of the burner and reduce its cost, we only plan one Th thermocouple and / or a single electric ignition device Aā„“ which are then associated with the operation of the single burner central.
