Description

La présente invention se rapporte à un foyer à gaz pour table de cuisson formé de trois pièces mécaniques totalement dissociables dans lequel la grille-support des récipients culinaires est utilisée pour la stabilité de la flamme. The present invention relates to a hearth gas cooktop made of three pieces totally dissociable mechanical in which the support grid for cooking vessels is used for flame stability.

Un brûleur de cuisinière ou de table de cuisson à gaz se compose de façon traditionnelle d'un corps de brûleur monobloc, d'un chapeau plat ou bombé posé sur l'extrémité supérieure de ce corps et d'une grille-support qui porte les récipients culinaires. La surface latérale de la pièce formant le chapeau est traversée d'une multitude d'orifices de sortie du gaz disposés en couronne pour donner naissance à des flammes élémentaires qui, réunies entre elles, constituent la flamme du brûleur. A stove or table burner gas cooking traditionally consists of a monobloc burner body, flat or domed cap placed on the upper end of this body and a support grid which carries the cooking vessels. The lateral surface of the part forming the cap is through a multitude of gas outlet ports arranged in a crown to give birth to elementary flames which, joined together, constitute the burner flame.

Cette grille constitue une unité fonctionnelle séparée. This grid constitutes a unit separate functional.

En effet, si elle entoure à distance le corps du brûleur de par sa forme et sa fonction de soutien des récipients au-dessus du brûleur, elle ne présente aucun lien mécanique avec celui-ci. Au contraire, une indépendance totale semble être voulue entre le corps du brûleur et la grille-support. Indeed, if it remotely surrounds the body of the burner by its shape and its support function containers above the burner, it does not have no mechanical link with it. On the contrary, a total independence seems to be desired between the body of the burner and the support grid.

Par ailleurs, le brûleur doit être protégé des produits culinaires pouvant se déverser des récipients et des projections de toute sorte. Furthermore, the burner must be protected culinary products that may spill containers and projections of all kinds.

Pour ce faire, un support supplémentaire de protection, par exemple conformé en assiette, entoure la base du brûleur. To do this, additional support of protection, for example plate-shaped, surrounds the base of the burner.

Lorsque ce support n'existe pas, une conformation spéciale en remontée du fond de table de cuisson au niveau de la naissance du corps du brûleur évite aux matières se déversant des récipients culinaires de noyer le brûleur. When this support does not exist, a special conformation in raising the table bottom cooking at the birth of the burner body prevents materials spilling from containers culinary to drown the burner.

Ces pièces annexes ou la conformation du fond de table de cuisson utilisées en combinaison avec une grille encombrante et difficile à enlever n'apportent pas toutes les facilités d'usage de la ménagère, notamment en ce qui concerne la cuisson et le nettoyage. These additional parts or the shape of the bottom hob used in combination with a bulky grid and difficult to remove do not bring   not all the ease of use of the housewife, especially as regards relates to cooking and cleaning.

Le document EP-0 123 007 décrit un foyer à gaz où une plaque formant la grille est stabilisée et fixée sur la table de cuisson. Document EP-0 123 007 describes a gas fireplace where a plate forming the grid is stabilized and fixed on the hob.

Le document DE-1 127 061 décrit un foyer à gaz où l'embase et la grille support forment un ensemble solidaire comportant sept pièces. Document DE-1 127 061 describes a gas fireplace where the base and the support grid forms an integral assembly comprising seven parts.

Le document FR-2 369 504 décrit un foyer à gaz où le conduit coudé est vissé directement dans l'embase. Document FR-2 369 504 describes a gas fireplace where the flue angled is screwed directly into the base.

La fabrication et le montage de ces brûleurs s'avèrent délicats et onéreux en raison des formes complexes et des difficultés de montage à travers la paroi. The manufacture and assembly of these burners is delicate and expensive due to the complex shapes and the difficulty of mounting through the wall.

Par ailleurs, pour éviter l'extension de la flamme due à la pression du gaz, la couronne de flammes doit être resserrée, c'est-à-dire ramenée vers les orifices de sortie par autant de forces concentriques que nécessaire. Furthermore, to avoid the extension of the flame due to the pressure gas, the crown of flames must be tightened, i.e. brought back towards the exit orifices by as many concentric forces as necessary.

Une première technique consiste à utiliser un brûleur dont le trajet initial des flammes est dirigé vers le haut puis à rabattre la couronne de flammes vers le bas par un couvercle supérieur dont le rebord périphérique oblige les flammes à s'incurver vers le bas avant de se développer radialement. A first technique consists in using a burner whose path initial of the flames is directed upwards then to fold down the crown of flames down by an upper cover with a peripheral rim forces the flames to curve down before developing radially.

Le trajet naturel des flammes ainsi contrarié évite la dislocation par éclatement de la couronne de flammes. The natural path of the flames thus thwarted avoids dislocation by bursting of the crown of flames.

Une autre technique utilisée consiste à créer une flamme dite pilote. Il s'agit d'une flamme secondaire de petite puissance disposée également en couronne et prenant naissance en-dessous de la flamme principale. Another technique used is to create a so-called flame pilot. It is a secondary flame of small power arranged also in crown and arising below the flame main.

La présence de cette flamme secondaire qui se confond avec la flamme principale permet, grâce à divers effets, dont les effets thermiques et aérauliques, de garder la flamme entière et serrée près des orifices de sortie. The presence of this secondary flame which merges with the main flame allows, thanks to various effects, including thermal effects and keep the whole flame tight and close to the orifices of exit.

Cette flamme pilote peut exister grâce à un intervalle supplémentaire de sortie du gaz situé dans la tête du brûleur immédiatement sous la couronne de la flamme principale dans la paroi latérale adjacente. This pilot flame can exist thanks to an interval additional gas outlet located in the burner head immediately under the main flame crown in the adjacent side wall.

Dans la variante de base du foyer à trois pièces principales, à savoir une embase, un corps de brûleur et une grille-support concentrique venant se poser sur l'embase, l'intervalle de flamme pilote est celui ménagé entre la sous-face du chapeau du brûleur et l'extrémité frontale supérieure de la saillie centrale cylindrique de l'embase. Cet intervalle est obtenu et maintenu par des entretoises conformées dans la sous-face du chapeau par lesquelles le brûleur s'appuie sur la face frontale supérieure de l'embase. la hauteur de ces entretoises détermine la largeur de la fente correspondante. In the basic variant of the three main room fireplace, know a base, a body of   burner and a concentric support grid coming to rest on the base, the pilot flame interval is that between the underside of the cap of the burner and the upper front end of the cylindrical central projection of the base. This interval is obtained and maintained by spacers shaped in the underside of the cap by which the burner is supported on the upper front face of the base. the height of these spacers determines the width of the corresponding slot.

L'embase doit rester fixe car elle assure, d'une part le contact mécanique avec le plan-support et l'appui-maintien du coude d'alimentation par une pièce de fermeture et d'autre part l'étanchéité. The base must remain fixed because it ensures, on the one hand the contact mechanical with support and support elbow support by a closing piece and on the other hand the sealing.

La saillie centrale cylindrique de l'embase nécessairement fixe peut diminuer de hauteur et procurer ainsi une plus grande facilité de nettoyage en utilisant le rebord de la partie centrale de la grille pour la création de l'intervalle donnant naissance à la flamme pilote. The cylindrical central projection of the necessarily fixed base can decrease in height and thus provide greater ease of cleaning using the rim of the central part of the grid for the creation of the interval giving birth to the pilot flame.

La présente invention a pour but de supprimer globalement les inconvénients ci-dessus et permettre la réalisation en série de brûleurs à trois pièces avec flamme pilote, notamment ceux dans lesquels l'embase est de forme la plus plate possible par utilisation de la grille-support en association avec la tête du brûleur pour constituer la fente de sortie de la flamme pilote. The object of the present invention is to generally eliminate the disadvantages above and allow the serial production of burners to three pieces with pilot flame, especially those in which the base is as flat as possible by using the support grid in association with the burner head to constitute the outlet slot of the pilot flame.

Pour ce faire, deux des pièces, à savoir la grille-support et la tête du brûleur sont emmanchées coaxialement l'une sur l'autre et la grille présente un rebord supérieur en prolongation de sa partie centrale, rebord dont la face frontale supérieure est utilisée comme paroi inférieure de la fente de création de la flamme pilote. To do this, two of the parts, namely the support grid and the head of the burner are fitted coaxially one on top of the other and the grate has an upper rim in extension of its central part, rim whose upper front face is used as the lower wall of the pilot flame creation slot.

Plus précisément, l'invention a pour objet un foyer à gaz pour table de cuisson ou cuisinière à gaz selon la revendication 1. More specifically, the invention relates to a gas fireplace for The hob or gas stove according to claim 1.

L'invention confère des avantages particulièrement intéressants liés à la constitution du foyer en trois pièces dont le corps du brûleur et la grille sont dissociables de l'embase. Ainsi, le nettoyage du plan de cuisson s'en trouve encore facilité. The invention provides particularly advantageous advantages linked to the constitution of the home   in three parts including the burner body and the grate are separable from the base. So cleaning the cooking plan is further facilitated.

Le nettoyage du foyer ne peut être plus simple : il suffit de dissocier les pièces composantes pour libérer un espace suffisant autour de l'embase pour nettoyer commodément globalement toute la partie visible autour du brûleur. The cleaning of the fireplace cannot be more simple: just dissociate the component parts to free up sufficient space around the base to conveniently clean the entire area visible around the burner.

Par ailleurs, la grille et la tête du brûleur se dissociant facilement et entièrement de l'embase peuvent être individualisées et nettoyées ou lavées séparément, par exemple dans un appareil électroménager lave-vaisselle comme tout ustensile culinaire. In addition, the grate and the burner head easily and completely dissociated from the base can be individualized and cleaned or washed separately, for example in a household appliance dishwasher like any other cooking utensil.

Finalement, le montage de ce brûleur s'effectue comme un jeu de construction en raison de l'association par simple engagement coaxial d'une pièce sur l'autre. Finally, the mounting of this burner is like a building set because of association by simple coaxial engagement of a part on the other.

Selon la variante à embase plate, ces mêmes avantages sont amplifiés. According to the flat base variant, these same benefits are magnified.

De plus, la réalisation des pièces mécaniques, notamment l'embase et la grille, s'en trouve facilitée. In addition, the production of parts mechanical, in particular the base and the grid, finds it easier.

Finalement, le montage du foyer sur le plan de cuisson et son démontage s'effectuent plus rapidement et avec la même facilité. Finally, the assembly of the fireplace on the plan cooking and disassembly is more quickly and with the same ease.

Le foyer à gaz pour cuisinières ou tables de cuisson, par exemple domestique, selon l'invention se compose d'une embase et de deux autres pièces totalement, rapidement et facilement dissociables, à savoir une grille-support et le chapeau du brûleur. The gas fireplace for cookers or tables cooking, for example domestic cooking, according to the invention consists of a base and two other parts totally, quickly and easily dissociable, know a support grid and the burner cap.

Selon une des caractéristiques de la deuxième invention, la partie centrale de la grille support du foyer est utilisée comme un des moyens, avec la sous-face de la tête du brûleur, pour créer la flamme dite pilote, c'est-à-dire la flamme annexe inférieure permettant d'accrocher la flamme principale. According to one of the characteristics of the second invention, the central part of the support grid of the fireplace is used as one of the means, with the underside of the burner head, to create the so-called flame pilot, i.e. the lower annex flame allowing to hang the main flame.

Les pièces constituantes du foyer selon l'invention se montent sur un plan 1 de cuisson totalement plat d'une table de cuisson ou d'une cuisinière. Ce plan présente un passage 2 pour un raccord d'alimentation coudé 3 apportant le mélange gazeux combustible au brûleur. Ce coude 3 émerge de la face supérieure par un tronçon droit 4. The components of the fireplace according to the invention is mounted on a cooking surface 1 completely flat from a hob or cooker. This plan shows a passage 2 for a elbow supply connection 3 providing the mixture combustible gas at the burner. This elbow 3 emerges from the upper face by a straight section 4.

Se développe coaxialement autour de ce tronçon une embase 5 en couronne circulaire servant de base-support à un chapeau 6 plat ou bombé faisant partie d'une tête 7 constituant l'ensemble appelé classiquement brûleur. Coaxially develops around this section a base 5 in a circular crown serving as support base to a flat or domed cap 6 making   part of a head 7 constituting the assembly called conventionally burner.

L'embase présente un épaulement périphérique double 8 prolongé vers le haut, pour le premier mode d'exécution, par un tronçon cylindrique creux et coaxial 9 terminé par une face frontale annulaire plane 10. The base has a peripheral shoulder double 8 extended upwards, for the first mode of execution, by a hollow cylindrical section and coaxial 9 terminated by a flat annular front face 10.

La tête plate 7 présente sur sa face latérale une succession périphérique de fentes individualisées telles que 11 disposées en couronne correspondant chacune à la sortie d'une flamme plate en nappe. The flat head 7 has on its side face a peripheral succession of individualized slots such as 11 arranged in corresponding crown each at the exit of a flat sheet flame.

La tête se prolonge vers le bas par une saillie cylindrique inférieure 12 de plus petit diamètre dont la naissance délimite un épaulement 13 entouré d'une bordure plane 14 de sous-face de laquelle émergent des surépaisseurs jouant le rôle d'entretoises (non représentées) permettant de ménager avec un rebord périphérique en regard un intervalle libre 15 en-dessous de la couronne des fentes 11, intervalle nécessaire à la création de la ou des flamme(s) pilote(s) ou d'accrochage de la flamme principale. The head is extended downwards by a 12 smaller cylindrical lower projection diameter whose birth delimits a shoulder 13 surrounded by a flat border 14 on the underside of which emerge from the thicknesses playing the role of spacers (not shown) for cleaning with a ledge peripheral opposite a free interval 15 below of the crown of the slots 11, interval necessary for the creation of the flame (s) pilot (s) or hooking the main flame.

La tête 7 est simplement posée sur l'embase 5 et peut donc facilement se dissocier de celle-ci. The head 7 is simply placed on the base 5 and can therefore easily dissociate from it.

Ce brûleur se complète par une grille-support 16 à quatre branches telles que 17 comportant une partie centrale 18 en couronne dont le bord présente un profil complémentaire 19 à celui de l'épaulement de l'embase venant se placer par emmanchement et appui-calage sur l'épaulement double de l'embase. This burner is completed by a support grid 16 with four branches such as 17 comprising a central part 18 in a crown, the edge of which has a profile 19 complementary to that of the shoulder of the base coming to be placed by fitting and wedging support on the double shoulder of the base.

Selon la variante représentée, les branches comportent des pattes radiales incurvées telles que 20 raccordées en tangente à partir de la couronne centrale 18 procurant à l'ensemble un aspect de torsade ou de volute. Les parties supérieures 21 en L de ces branches, sont de forme technique classique pour le soutien des récipients culinaires. According to the variant shown, the branches have curved radial legs such as 20 tangent from the central crown 18 providing the whole with a twisted or volute. The upper parts 21 in L of these branches, are of classic technical form for the support for cooking vessels.

L'embase 5 est montée de façon amovible ou solidarisée au plan 1 de cuisson par l'intermédiaire de fixations telles que 22 la réunissant à travers le plan 1 à une prolongation latérale ou col 23 du coude 3 (figure 8). The base 5 is removably mounted or   secured to the cooking surface 1 via bindings such as 22 bringing it together across the plane 1 to a lateral extension or neck 23 of the elbow 3 (figure 8).

Plus précisément en se reportant aux figures accompagnantes, l'épaulement périphérique double de l'embase 5 sur lequel s'emmanche et s'appuie à calage le bord périphérique intérieur de la partie centrale 18 de la grille-support 16 présente un profil complémentaire à celui de ladite grille, c'est-à-dire pour l'exemple représenté, une rampe conique 24 suivie d'un épaulement droit 25. More specifically by referring to the figures accompanying, the double peripheral shoulder of the base 5 on which is fitted and rests in place the inner peripheral edge of the central part 18 of the support grid 16 has a complementary profile to that of said grid, that is to say for the example shown, a conical ramp 24 followed by a right shoulder 25.

Bien entendu, les profils complémentaires de ces bords peuvent affecter différentes formes, par exemple celle d'un épaulement droit avec ou sans butée permettant de réaliser un emmanchement cylindrique simple ou toute autre forme de profil assurant un emmanchement et un calage. Of course, the complementary profiles of these edges can have different shapes, for example example that of a straight shoulder with or without stop allowing a cylindrical fitting simple or any other form of profile ensuring fitting and wedging.

Pour la dissociation en vue du nettoyage ou d'une intervention technique, il suffit de soulever le chapeau du brûleur pour libérer le passage de la partie centrale de la grille. Celle-ci, simplement emmanchée sur la grille, s'enlève facilement par un simple mouvement vertical. La grille et le chapeau du brûleur, totalement libres, peuvent alors être introduits facilement dans un appareil électroménager lave-vaisselle. For dissociation for cleaning or of a technical intervention, just lift the burner cap to free the passage of the part central grid. This one, simply fitted on the grid, easily removed with a simple vertical movement. The burner grate and cap, completely free, can then be entered easily in a dishwasher appliance.

Plus particulièrement, selon la deuxième forme d'exécution, on conforme le haut de la partie centrale de la grille-support en rebord supérieur circulaire relevé à front supérieur plan destiné à former avec l'épaulement inférieur de sous-face de la tête du brûleur l'intervalle 15 constituant la fente qui donne naissance à la flamme pilote. More specifically, according to the second form of execution, we conform the top of the part central support grid on upper edge circular raised up front plan intended for form with the lower shoulder of the underside of the burner head gap 15 constituting the slot which gives birth to the pilot flame.

Selon une caractéristique du deuxième mode d'exécution de l'invention, l'embase 5 affecte une forme générale circulaire plate. Elle présente un épaulement périphérique extérieur conique 26 et un disque central 27 faiblement en saillie, délimitant entre son chant circulaire extérieur et le rebord périphérique extérieur conique 26 une plage annulaire d'appui 28. According to a characteristic of the second mode of the invention, the base 5 affects a general circular flat shape. It presents a   outer conical shoulder 26 and a central disc 27 slightly protruding, delimiting between its outer circular edge and the ledge conical outer device 26 an annular range support 28.

De la tête 7 du brûleur sortent les flammes selon une couronne. Cette tête présente sur sa face latérale une succession périphérique d'orifices circulaires ou les fentes individualisées 11 correspondant chacune à la sortie d'une flamme élémentaire selon la forme d'un dard ou plate selon une nappe, destinée chacune à constituer une couronne de flammes radiales ou une corolle. From the burner head 7 the flames come out according to a crown. This head present on its face lateral a peripheral succession of orifices circular or individualized slots 11 each corresponding to the exit of a flame elementary according to the shape of a dart or flat according to a tablecloth, each intended to constitute a crown of radial flames or a corolla.

La tête 7 se prolonge vers le bas par la saillie cylindrique inférieure 12 de plus petit diamètre dont la naissance délimite l'épaulement 13 entouré de la bordure plane 14 de sous-face, de laquelle émergent les surépaisseurs jouant le rôle d'entretoises (non représentées) permettant de ménager avec un rebord périphérique en regard un intervalle libre 15 nécessaire à la création de la ou des flammes pilotes ou d'accrochage de la flamme principale. The head 7 is extended downwards by the 12 smaller cylindrical lower projection diameter whose birth delimits the shoulder 13 surrounded by the flat edge 14 of the underside, of which emerge the extra thicknesses playing the role spacers (not shown) to spare with a peripheral edge opposite an interval free 15 necessary for the creation of the flame (s) pilot or hooking the main flame.

Le corps du brûleur repose en appui par la face frontale inférieure de la saillie cylindrique 12 du brûleur sur le disque central de l'embase 5 et peut donc facilement se dissocier de celle-ci. The burner body rests in support by the lower front face of the cylindrical projection 12 of the burner on the central disc of the base 5 and can so easily dissociate from it.

Le foyer se complète par la grille-support 16 qui comprend comme précédemment quatre branches 17 du même type comportant une partie centrale 18 en couronne dont le bord inférieur présente un profil complémentaire 19 à celui du double épaulement périphérique extérieur de l'embase 5 pour venir se placer par emmanchement et appui-calage sur le rebord périphérique extérieur et la plage annulaire de l'embase 5. The fireplace is completed by the support grid 16 which includes as before four branches 17 of the same type comprising a central part 18 in a crown the lower edge of which has a profile complementary to that of the double shoulder peripheral device of the base 5 to come place by fitting and wedging on the edge external device and the annular range of the base 5.

Conformément à ce mode d'exécution, la grille-support 16 comporte en plus, à l'extrémité supérieure de sa partie centrale 18, un rebord périphérique supérieur relevé, par exemple étroit, 29 droit et à face frontale supérieure plane 30. Ce rebord est disposé en alignement coaxial avec la face latérale inférieure cylindrique de la partie centrale intérieure. In accordance with this embodiment, the support grid 16 further comprises, at the end   upper part of its central part 18, a rim upper peripheral raised, for example narrow, 29 straight and with flat upper front face 30. This rim is arranged in coaxial alignment with the side face cylindrical lower part of the central part interior.

La conformation de surface latérale extérieure de la partie centrale 18 de la grille assure une arrivée optimale d'air secondaire aux flammes pilote et principale. Un rebord étroit 29 en nervure circulaire à section carrée ou rectangulaire se prolongeant vers le bas par un décrochement 31 en retrait vers l'intérieur suivi d'une rampe conique 32 à forte pente constitue un exemple de formes techniques adaptées. The external lateral surface conformation of the central part 18 of the grid provides optimal supply of secondary air to pilot flames and main. A narrow rim 29 in circular rib with square or rectangular section extending towards the bottom by a recess 31 recessed inward followed by a steep conical ramp 32 constitutes a example of suitable technical forms.

La face frontale supérieure 30 est usinée de manière à être parfaitement plane. Elle est disposée en regard de la bordure de sous-face 14 de la tête 7 du brûleur pour servir à la création et au maintien de l'intervalle 15 donnant naissance à la flamme pilote. The upper front face 30 is machined from so as to be perfectly flat. It is arranged in look of the underside border 14 of the head 7 of the burner to be used for the creation and maintenance of the interval 15 giving rise to the pilot flame.

Cet écartement reste constant malgré les disparités de fabrication car la grille en tant que pièce décolletée sur ses faces de portée présente une hauteur de partie centrale constante. Ainsi, grâce à ce mode d'exécution de l'invention, on peut garantir la stabilité de la flamme principale. This spacing remains constant despite the manufacturing disparities because the grid as turned part on its bearing faces has a constant central height. So thanks to this mode of carrying out the invention, one can guarantee the stability of the main flame.

L'embase 5 est montée de façon amovible ou solidarisée au plan-support 1 de cuisson par l'intermédiaire d'une pièce de fixation à montage rapide telle que 33, par exemple du type à baïonnette, réunissant, à travers le plan 1, une prolongation latérale ou col 34 du coude 3. The base 5 is removably mounted or secured to the cooking support surface 1 by via a mounting fixture fast such as 33, for example of the bayonet type, bringing together, through plan 1, an extension lateral or neck 34 of the elbow 3.

Deux joints, par exemple toriques, 35 et 36 assurent l'étanchéité de part et d'autre du plan-support 1. Two seals, for example O-rings, 35 and 36 seal on either side of the support plane 1.

Plus précisément, en se reportant aux figures accompagnantes, l'épaulement périphérique extérieur conique 26 de l'embase 5 sur lequel s'emmanche et s'appuie le bord périphérique intérieur de la partie centrale 18 de la grille présente un profil complémentaire à celui de la grille. More specifically, referring to the figures accompanying, the outer peripheral shoulder conical 26 of the base 5 onto which is fitted and   rests on the inner peripheral edge of the part central 18 of the grid has a profile complementary to that of the grid.

Bien entendu, les profils complémentaires de ces bords peuvent affecter différentes formes, par exemple celle d'un épaulement droit avec ou sans butée permettant de réaliser un emmanchement cylindrique simple ou toute autre forme de profil assurant un emmanchement avec ou sans calage. Of course, the complementary profiles of these edges can have different shapes, for example example that of a straight shoulder with or without stop allowing a cylindrical fitting simple or any other form of profile ensuring fitting with or without setting.

Pour la dissociation en vue du nettoyage ou d'une intervention technique, il suffit de soulever le chapeau du brûleur afin de libérer le passage de la partie centrale de la grille. Celle-ci, simplement emmanchée sur l'embase, s'enlève facilement par un simple mouvement vertical. La grille et le chapeau du brûleur, totalement libres, peuvent alors être introduits facilement dans un appareil électroménager lave-vaisselle. For dissociation for cleaning or of a technical intervention, just lift the burner cap to free the passage of the central part of the grid. This one, simply fitted on the base, easily removed by a simple vertical movement. The grid and the hat of burner, totally free, can then be easily inserted into a household appliance dishwasher.

Il est bien entendu que le rebord circulaire supérieur de la grille peut être remplacé par une pièce intermédiaire. It is understood that the circular rim grid top can be replaced with a piece intermediate.
