- the space available for the gas injector and the air / gas mixer is relatively small, by compared to a conventional stove.
- the burner has a cap 3 and a head 4.
- the base 40 of the head 4 is not entirely flat. Her central part which has an orifice 41 for the gas supply is slightly raised by relative to the base of the slots 43 and then goes in declining towards the skirt 42.
- Reference 5 designates the gas injector, this gas is brought to the burner through orifice 41.
- This particular shape of the base 40 allows mix the air / gas in the space defined between the hat and base.
- this type of mixer is very sensitive to the positioning accuracy of the injector relative to axis 6 of the burner. For example, if the angle ⁇ that forms the injector with axis 6 of the burner is of the order of 1 °, this will produce a visible asymmetry of the flames which is due to local variations in air / gas ratio in the mixture.
- the cap 3 comprises a dome 35 which is hollowed out in the boss 33 provided on the inner face 31 of the cap 3.
- This dome has a concavity turned towards the base 40 of the burner head.
- this dome 35 defines a portion of spherical surface whose center is located at injector 5 and whose radius corresponds to the distance between the dome and the injector.

Abstract
Description
L'invention concerne un brûleur à gaz pour appareils de cuisson. Un tel brûleur ménage des orifices de sortie pour un mélange air/gaz, au niveau desquels des flammes peuvent se former.The invention relates to a gas burner for cooking. Such a burner provides outlet openings for an air / gas mixture, at which flames can form.
De façon générale, les brûleurs sont conçus pour pouvoir fonctionner quel que soit le gaz d'alimentation : gaz de ville, gaz naturel ou gaz de pétrole liquéfié.Generally, burners are designed to be able to operate regardless of the supply gas: city, natural gas or liquefied petroleum gas.
Il convient en particulier que les flammes qui se forment sur les orifices de sortie du mélange gaz/air restent stables, même en cas de variation des caractéristiques du mélange air/gaz.In particular, the flames that form on the gas / air mixture outlet ports remain stable, even if the characteristics of the air / gas mixture.
Plusieurs solutions ont déjà été proposées pour réaliser des brûleurs multigaz.Several solutions have already been proposed to achieve multigas burners.
On peut tout d'abord citer les brûleurs dits "à stabilisation par flamme pilote". Ces brûleurs comportent un chapeau dont le rebord est percé de trous et qui repose sur un support.We can first of all cite the so-called "burners" pilot flame stabilization ". These burners have a hat whose rim is pierced with holes and which rests on a support.
Les flammes principales qui se forment au niveau de ces trous sont stabilisées par une petite flamme, générée à la base et éventuellement au-dessus des flammes principales. Cette flamme pilote permet de réchauffer le mélange air/gaz de la flamme principale et rallume en permanence la flamme principale.The main flames that form at these holes are stabilized by a small flame, generated at the base and possibly above the flames main. This pilot flame is used to heat the air / gas mixture of the main flame and relight in permanently the main flame.
Cette solution a maintenant tendance a être abandonnée, car le brûleur est d'un coût de fabrication élevé. Par ailleurs, ce brûleur ne peut pas fonctionner à des puissances de gaz faibles. En effet, dans ce cas la flamme pilote a tendance à s'éteindre et les flammes principales deviennent alors sensibles aux courants d'air. Enfin, à une puissance élevée de la flamme pilote, le brûleur produit du CO. This solution now tends to be abandoned, because the burner has a high manufacturing cost. Through elsewhere, this burner cannot operate at low gas powers. Indeed, in this case the pilot flame tends to go out and the flames then become sensitive to currents air. Finally, at a high power of the pilot flame, the burner produces CO.
D'autres brûleurs, dits "autostabilisés", assurent la
stabilisation des flammes grâce à une forme particulière
de la section de sortie du mélange air/gaz.
Un tel brûleur est montré dans le brevet FR 2 161 354.Other burners, called "self-stabilized", ensure the
flame stabilization thanks to a special shape
of the air / gas mixture outlet section.
Such a burner is shown in
Un exemple de brûleur de ce type comporte un chapeau présentant un rebord périphérique, par lequel le chapeau repose sur un support. Des fentes sont ménagées dans ce rebord pour la sortie du mélange air/gaz.An example of such a burner has a cap having a peripheral rim, through which the cap rests on a support. Slots are provided in this rim for the outlet of the air / gas mixture.
Ces fentes sont étroites et leurs parois ont un profil trapézoïdal. Ainsi, à la partie de chaque fente présentant une forte épaisseur correspond une faible vitesse de sortie du mélange qui permet une retenue des flammes, tandis qu'à la partie de la fente présentant une faible épaisseur correspond un débit de mélange important.These slots are narrow and their walls have a profile trapezoidal. So at the part of each slot having a high thickness corresponds to a low exit speed of the mixture which allows retention of flames, while at the part of the slot presenting a thin corresponds to a mixing flow important.
Cette solution a connu un vif succès mais elle a été peu à peu abandonnée car elle n'est pas adaptée aux techniques nouvelles utilisant l'injection d'aluminium.This solution was a great success but it was little gradually abandoned because it is not suitable for new techniques using aluminum injection.
En effet, c'est le chapeau qui comporte les orifices de sortie du mélange air/gaz et il doit, par ailleurs, être réalisé en un matériau résistant à des températures élevées, ce qui n'est pas le cas de l'aluminium.Indeed, it is the hat which comprises the orifices of outlet of the air / gas mixture and it must also be made of a material resistant to temperatures which is not the case for aluminum.
Un autre exemple de brûleur de ce type est réalisé en deux parties, un chapeau en fonte ou acier émaillé qui est posé sur une tête, réalisée en aluminium injecté.Another example of a burner of this type is produced in two parts, a cast iron or enamelled steel hat which is placed on a head, made of injected aluminum.
La tête comporte une embase qui supporte une jupe périphérique. C'est dans cette jupe que sont formés les orifices de sortie du mélange air/gaz. The head has a base that supports a skirt peripheral. It is in this skirt that the air / gas mixture outlet ports.
Ces orifices sont constitués par des fentes plus ou moins profondes, disposées en alternance. Le chapeau repose directement sur la jupe de la tête de brûleur.These holes are formed by more or less slots deep, arranged alternately. The hat rests directly on the burner head skirt.
Les petites fentes laminent le mélange air/gaz et produisent des flammes qui sont plus courtes que les flammes principales issues des fentes les plus profondes. Ces flammes principales sont ainsi stabilisées.Small slits laminate the air / gas mixture and produce flames that are shorter than main flames from the deepest slits. These main flames are thus stabilized.
On a pu constater qu'avec ce type de brûleur, le gaz ne s'enflammait pas directement au contact de la tête de brûleur. Puisque ces brûleurs sont sensibles au soufflage des flammes, la proportion d'air dans le mélange air/gaz doit être limitée. Du fait de cette aération plus faible en air primaire, ces brûleurs nécessitent une bonne aération secondaire.We could see that with this type of burner, the gas does not did not ignite directly on contact with the head burner. Since these burners are sensitive to blowing flames, the proportion of air in the air / gas mixture must be limited. Due to this lower ventilation in primary air, these burners require good secondary ventilation.
Pour cela, les fentes principales doivent être très espacées et le diamètre de la tête de brûleur est donc relativement important. Par ailleurs, il est nécessaire de prévoir une hauteur sous grille relativement importante, toujours pour favoriser l'aération secondaire.For this, the main slots must be very spaced and the diameter of the burner head is therefore relatively large. By the way, it is necessary to provide a height under the grid relatively important, always to promote ventilation secondary.
La présente invention a pour but de pallier les inconvénients des brûleurs connus en proposant un brûleur à gaz adapté aux différents gaz de combustion, dont le coût de fabrication est réduit et qui est compatible avec une production en grande série et peut être utilisé avec une hauteur sous grille réduite et dans une large gamme de puissance de gaz.The object of the present invention is to overcome the disadvantages of known burners by proposing a burner gas suitable for different combustion gases, including manufacturing cost is reduced and that is compatible with mass production and can be used with reduced grid height and in a wide range of gas power.
Ainsi, l'invention concerne un brûleur à gaz pour appareils de cuisson, comportant une tête et un chapeau destiné à être posé sur la tête, la tête comportant une embase percée d'un orifice pour l'alimentation en mélange air/gaz et supportant une jupe périphérique dans laquelle sont ménagées des fentes sensiblement perpendiculaires au plan de l'embase, caractérisé en ce qu'il comprend une pluralité de plots sur la face supérieure de ladite jupe, chacun d'eux étant sensiblement à égale distance entre deux fentes adjacentes et situé au moins en partie dans la moitié intérieure de la face supérieure de ladite jupe, lesdits plots ménageant ainsi un espace entre le chapeau et la tête dans lequel une partie du mélange air/gaz est laminée.Thus, the invention relates to a gas burner for cooking appliances, comprising a head and a cap intended to be placed on the head, the head comprising a base pierced with a hole for the supply of mixture air / gas and supporting a peripheral skirt in which slots are provided which are substantially perpendicular to the plan of the base, characterized in that it comprises a plurality of studs on the upper face of said skirt, each of them being substantially equidistant between two adjacent slots and located at least partly in the inner half of the upper side of said skirt, said studs thus providing a space between the hat and head in which part of the mixture air / gas is laminated.
De préférence, la largeur desdits plots est inférieure à la moitié de l'épaisseur entre deux fentes adjacentes.Preferably, the width of said studs is less than half the thickness between two adjacent slots.
Egalement de préférence, la profondeur des plots est inférieure à la moitié de la profondeur des fentes ou encore de l'épaisseur de la jupe périphérique.Also preferably, the depth of the studs is less than half the depth of the slots or still of the thickness of the peripheral skirt.
Dans un mode préféré de réalisation, chaque plot comporte un côté situé dans le plan du bord intérieur de la jupe.In a preferred embodiment, each pad has one side located in the plane of the inner edge of the skirt.
De façon avantageuse, le chapeau du brûleur est légèrement débordant et comporte sur la périphérie de sa face intérieure un rebord formant bec, orienté vers la tête.Advantageously, the burner cap is slightly overflowing and has on the periphery of its inner face a lip forming a beak, oriented towards the head.
Avantageusement, le chapeau comporte également un bossage qui est sensiblement centré sur sa face intérieure.Advantageously, the hat also includes a boss which is substantially centered on its inner face.
L'invention concerne également un brûleur à gaz pour une table de cuisson.The invention also relates to a gas burner for a Cooktop.
Dans ce cas, l'orifice ménagé dans l'embase de la tête de brûleur permet l'alimentation en gaz provenant d'un injecteur et l'embase présente une forme appropriée pour réaliser un mélangeur air/gaz avec le chapeau du brûleur. In this case, the orifice made in the base of the head of burner allows the supply of gas from a injector and the base has a suitable shape for make an air / gas mixer with the burner cap.
Selon l'invention, le chapeau comporte en creux dans sa face intérieure un dôme dont la concavité est tournée vers la tête de brûleur.According to the invention, the hat has hollow in its inside face a dome whose concavity is turned towards the burner head.
De façon préférée, ce dôme forme une portion de surface sphérique dont le centre est situé sur l'injecteur et dont le rayon correspond à la distance entre le dôme et l'injecteur.Preferably, this dome forms a portion of surface spherical whose center is located on the injector and whose radius corresponds to the distance between the dome and the injector.
De préférence, la tête et le chapeau ont une forme sensiblement circulaire ou encore ovale.Preferably, the head and the hat have a shape substantially circular or even oval.
La tête de brûleur est avantageusement réalisée par injection d'aluminium, tandis que le chapeau est obtenu par moulage ou formage de fonte ou d'acier.The burner head is advantageously produced by aluminum injection, while the cap is obtained by casting or forming cast iron or steel.

Le fonctionnement du brûleur selon l'invention va maintenant être expliqué en référence aux figures 4 à 6.The operation of the burner according to the invention will now be explained with reference to Figures 4 to 6.
Un mélange air/gaz, produit par un mélangeur non illustré
sur les figures, arrive dans l'espace ménagé entre la
tête et le chapeau du brûleur, par l'orifice 21 ménagé
dans l'embase 20. Le flux correspondant est illustré par
la flèche F.An air / gas mixture, produced by a mixer not shown
in the figures, arrives in the space formed between the
burner head and cap, through
Ce flux de mélange gaz/air se dirige alors vers les
orifices de sortie constitués par les fentes 23 et
l'espace ménagé entre les plots 25.This gas / air mixture flow then goes to the
outlet orifices constituted by the
La partie la plus importante du mélange gaz/air,
illustrée par la flèche F1 sort par les fentes 23. C'est
au niveau de ces fentes que les flammes principales vont
se former.The most important part of the gas / air mixture,
illustrated by the arrow F1 exits through the
Une fraction du mélange gaz/air, illustrée par la flèche
F2, s'écoule dans l'espace ménagé entre les plots et
entre la face supérieure 24 de la jupe et la face
intérieure 11 du chapeau.A fraction of the gas / air mixture, illustrated by the arrow
F2, flows into the space between the studs and
between the

La partie du mélange air/gaz qui passe entre les plots 25
est laminée par le passage ménagé entre la face
supérieure de la jupe et la face intérieure du chapeau.The part of the air / gas mixture which passes between the
A ce niveau, une flamme de pilotage va se développer. Vu de l'extérieur, le brûleur selon l'invention présente donc une fente ininterrompue sous le chapeau au niveau de laquelle se développe la flamme de pilotage qui va ainsi stabiliser les flammes principales par le haut.At this level, a pilot flame will develop. Viewed from the outside, the burner according to the invention has so an uninterrupted slit under the hat at which develops the pilot flame which goes thus stabilize the main flames from above.
Il a été mis en évidence que le positionnement des plots
25 était important. En particulier, le brûleur ne
fonctionne pas de façon appropriée lorsque les plots sont
situés sur le bord latéral 28 des fentes 23.It was highlighted that the positioning of the
Il a été également montré que le fonctionnement du
brûleur était sensiblement amélioré lorsque les plots
étaient positionnés vers le bord intérieur 26 de la jupe
périphérique 22. En particulier, le brûleur ne fonctionne
pas de manière satisfaisante lorsque les plots sont
situés sur le bord extérieur 29 de la jupe périphérique.It has also been shown that the functioning of the
burner was significantly improved when the studs
were positioned towards the
Comme déjà illustré sur la figure 1, le chapeau 1
comporte sur sa face intérieure 11, un rebord 12 formant
bec et orienté vers la tête.As already illustrated in Figure 1, the cap 1
has on its inner face 11, a
Le chapeau déborde légèrement de la tête, si bien que le
rebord 12 est situé à distance de la sortie des flammes
principales et pilote. The hat protrudes slightly from the head, so that the
Ce rebord permet de créer une turbulence dans la flamme pilote. Celle-ci définit une zone de recirculation de la flamme pilote avec le haut des flammes principales, ce qui contribue à les stabiliser.This rim creates turbulence in the flame pilot. This defines a recirculation zone for the pilot flame with the top of the main flames, this which helps stabilize them.
Ainsi, ce rebord 12 permet à la flamme pilote disposée
au-dessus des flammes principales d'être aussi efficace
qu'une flamme pilote disposée à la base des flammes
principales.Thus, this
La figure 4 illustre la forme des flammes principales, lorsque le débit de mélange air/gaz est relativement fort.Figure 4 illustrates the shape of the main flames, when the air / gas mixture flow is relatively strong.
La figure 6 illustre la forme des flammes principales, lorsque le débit de mélange air/gaz est réduit. Dans ce cas, la flamme principale vient naturellement se nicher sous le chapeau 1 du brûleur. Du fait de la continuité de la fente ménagée sous le chapeau du brûleur pour la flamme de pilotage, celle-ci assure le réallumage de la partie des flammes principales qui viendraient à s'éteindre, par exemple du fait d'un courant d'air.Figure 6 illustrates the shape of the main flames, when the air / gas mixture flow is reduced. In this case, the main flame naturally comes to nest under the burner cap 1. Due to the continuity of the slot under the burner cap for pilot flame, this ensures the reignition of the part of the main flames that would come to go out, for example due to a draft.
On a pu ainsi constater que le brûleur selon l'invention permettait un fonctionnement approprié dans une large gamme de valeur de débit du mélange air/gaz. En particulier, le fonctionnement du brûleur est possible dans un rapport entre le débit minimum et le débit nominal du mélange air/gaz qui est de l'ordre de 1/10.It has thus been found that the burner according to the invention allowed proper operation over a wide air / gas mixture flow value range. In particular, the operation of the burner is possible in a relationship between minimum flow and flow nominal air / gas mixture which is of the order of 1/10.
Comme déjà illustré sur la figure 1, le chapeau 1 du
brûleur comporte également un bossage 13 sur sa face
intérieure 11.As already illustrated in FIG. 1, the cap 1 of the
burner also has a
Ce bossage diminue la vitesse de la partie du mélange air/gaz qui passe dans l'espace ménagé entre les plots et entre la face supérieure de la jupe et la face intérieure du chapeau, qui est illustrée par les flèches F2 sur les figures 4 et 5.This boss decreases the speed of the part of the mixture air / gas which passes through the space provided between the studs and between the upper side of the skirt and the inner side of the hat, which is illustrated by the arrows F2 on the Figures 4 and 5.
Ce bossage permet d'améliorer sensiblement la stabilité des flammes, avec des gaz ayant une tendance au soufflage.This boss significantly improves stability flames, with gases tending to blowing.
De façon générale, on constate que le passage ou fente ménagé entre la face supérieure de la jupe et le chapeau apporte une meilleure stabilisation des flammes principales. Ceci est notamment dû au fait que la flamme pilote est, en pratique, reliée aux flammes principales, ce qui permet d'utiliser le brûleur dans une grande gamme de débit de mélange air/gaz.In general, we see that the passage or slot formed between the upper face of the skirt and the hat provides better flame stabilization main. This is notably due to the fact that the flame pilot is, in practice, connected to the main flames, which allows the burner to be used in a wide range air / gas mixture flow rate.
Ce brûleur peut donc être plus aéré en air primaire que les brûleurs qui ne comportent pas une telle fente pour la flamme pilote.This burner can therefore be more ventilated in primary air than burners that do not have such a slot for the pilot flame.
Par ailleurs, le brûleur selon l'invention peut fonctionner avec une hauteur sous grille, c'est-à-dire avec une hauteur entre le plan de cuisson et le fond d'un récipient, qui est limitée.Furthermore, the burner according to the invention can operate with a height under the grid, i.e. with a height between the hob and the bottom of a container, which is limited.
Ce brûleur peut par exemple fonctionner avec une hauteur sous grille comprise entre 25 et 30 mm, alors que les brûleurs traditionnels nécessitent une hauteur sous grille comprise entre 35 et 45 mm.This burner can for example operate with a height under grid between 25 and 30 mm, while the traditional burners require a height under grid between 35 and 45 mm.
Cette hauteur sous grille réduite est notamment possible car le brûleur selon l'invention nécessite moins d'aération secondaire, l'aération primaire pouvant être relativement importante.This reduced height under the grid is notably possible because the burner according to the invention requires less secondary ventilation, primary ventilation can be relatively large.
Cependant, pour favoriser l'aération secondaire, il est
préférable que les fentes 23 de la tête de brûleur soient
relativement espacées les unes des autres. However, to promote secondary ventilation, it is
preferable that the
On constate de plus que la présence d'une flamme pilote au-dessus des flammes principales, et non à leur base, améliore l'hygiène de combustion dans des conditions limites de fonctionnement du brûleur.We also note that the presence of a pilot flame above the main flames, not at their base, improves combustion hygiene under conditions burner operating limits.
On se réfère maintenant à la figure 7 qui illustre un brûleur selon l'invention, conçu pour une table de cuisson.We now refer to Figure 7 which illustrates a burner according to the invention, designed for a table cooking.
Dans ce cas, l'espace disponible pour l'injecteur de gaz et le mélangeur air/gaz est relativement réduit, par rapport à une cuisinière classique.In this case, the space available for the gas injector and the air / gas mixer is relatively small, by compared to a conventional stove.
C'est pourquoi, le brûleur est alors conçu pour que le mélange air/gaz soit réalisé dans le brûleur lui-même.This is why the burner is then designed so that the air / gas mixture is produced in the burner itself.
Le brûleur comporte un chapeau 3 et une tête 4.The burner has a
L'embase 40 de la tête 4 n'est pas entièrement plane. Sa
partie centrale qui comporte un orifice 41 pour
l'alimentation en gaz est légèrement surélevée par
rapport à la base des fentes 43 et va ensuite en
déclinant en direction de la jupe 42.The
La référence 5 désigne l'injecteur de gaz, ce gaz est
amené au brûleur par l'orifice 41.
Cette forme particulière de l'embase 40 permet de
réaliser le mélange air/gaz dans l'espace défini entre le
chapeau et l'embase.This particular shape of the
On constate que ce type de mélangeur est très sensible à
la précision du positionnement de l'injecteur par rapport
à l'axe 6 du brûleur. Par exemple, si l'angle α que forme
l'injecteur avec l'axe 6 du brûleur est de l'ordre de 1°,
ceci va produire une dissymétrie visible des flammes
principales, qui est due aux variations locales du
rapport air/gaz dans le mélange.We see that this type of mixer is very sensitive to
the positioning accuracy of the injector relative
to
C'est pourquoi, dans le mode de réalisation du brûleur
illustré à la figure 7, le chapeau 3 comporte un dôme 35
qui est ménagé en creux dans le bossage 33 prévu sur la
face intérieure 31 du chapeau 3.Therefore, in the embodiment of the burner
illustrated in FIG. 7, the
Ce dôme présente une concavité tournée vers l'embase 40
de la tête du brûleur. De préférence, ce dôme 35 définit
une portion de surface sphérique dont le centre est situé
au niveau de l'injecteur 5 et dont le rayon correspond à
la distance entre le dôme et l'injecteur.This dome has a concavity turned towards the
La présence de ce dôme 35 permet d'assurer un
fonctionnement correct du brûleur, même si l'angle a est
d'environ 3° et si l'axe de l'injecteur est écarté
d'environ 2 mm par rapport à l'axe 6 du brûleur
(référence p).The presence of this
Ce dôme 35 permet donc d'améliorer la souplesse du
montage du brûleur selon l'invention.This
A titre d'exemple, vont maintenant être indiquées des dimensions fonctionnelles pour un brûleur selon l'invention ayant une puissance nominale de 3500 W.By way of example, will now be indicated functional dimensions for a burner according to the invention having a nominal power of 3500 W.
Ces dimensions sont indiquées dans le tableau ci-dessous, les cotes mentionnées dans le tableau sont indiquées sur les figures 3, 6 et 7 pour faciliter la compréhension. These dimensions are indicated in the table below, the dimensions mentioned in the table are indicated in Figures 3, 6 and 7 to facilitate understanding.
Bien que l'invention ait été décrite en liaison avec des modes de réalisation particuliers, elle n'est nullement limitée à ces modes de réalisation et elle comprend tous les équivalents techniques des moyens décrits, ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention.Although the invention has been described in connection with particular embodiments, it is by no means limited to these embodiments and it includes all the technical equivalents of the means described, as well as their combinations if these fall within the scope of the invention.
En particulier, dans les exemples décrits, un plot est systématiquement prévu entre deux fentes pour les flammes principales. Un brûleur selon l'invention peut comprendre un nombre plus limité de plots, dans la mesure où les plots prévus permettent effectivement de générer une flamme pilote, distincte de la flamme principale.In particular, in the examples described, a stud is systematically provided between two slots for the flames main. A burner according to the invention can comprise a more limited number of studs, insofar as the planned studs effectively generate a pilot flame, separate from the main flame.
Par ailleurs, le mode de réalisation du chapeau de brûleur illustré à la figure 7, comportant un dôme sur la face intérieure du chapeau, pourrait être utilisé avec une tête de brûleur quelconque, ne comportant pas nécessairement des plots entre les fentes pour les flammes principales.Furthermore, the embodiment of the hat of burner illustrated in Figure 7, with a dome on the inner side of hat, could be used with any burner head, not including necessarily studs between the slots for the main flames.
Enfin, les signes de référence insérés après les caractéristiques techniques figurant dans les revendications ont pour seul but de faciliter la compréhension de ces dernières et ne sauraient en limiter la portée.Finally, the reference signs inserted after the technical characteristics appearing in the claims are intended only to facilitate the understanding of these and cannot limit them the scope.
