Description

La présente invention se rapporte a une table de cuisson comportant un plan de cuisson, un cadre et un carter assemblés de façon étanche et comportant un dispositif pour assurer l'étanchéité de la table de cuisson avec un support. La présente invention se rapporte aussi à un procédé d'assemblage étanche de la table de cuisson.The present invention relates to a hob comprising a hob, a frame and a housing assembled in such a way waterproof and comprising a device for sealing the table cooking with a support. The present invention also relates to a waterproof assembly process of the hob.

Dans une cuisine domestique, lorsqu'on assemble une table de cuisson avec un support, par exemple un plan de travail, il est nécessaire de prévoir une étanchéité afin d'éviter que des particules solides ou des liquides ne puissent s'intercaler entre ces deux éléments. Généralement, une bande de joint par exemple silicone est fournie avec la table de cuisson. Ainsi l'installateur assure l'étanchéité en pressant ce joint entre la table de cuisson et le plan de travail.In a domestic kitchen, when you assemble a table cooking with a support, for example a worktop, it is necessary to provide a seal to prevent solid particles or liquids cannot be inserted between these two elements. Usually, a seal strip, for example silicone, is supplied with the hob. Thus the installer ensures the tightness by pressing this joint between the table cooking and worktop.

Par ailleurs, la table de cuisson selon le DE-A-3227058 comporte généralement plusieurs éléments tels que par exemple un plan de cuisson, un cadre et un carter. Il est nécessaire de prévoir une étanchéité comparable à celle décrite précédemment. Cette étanchéité est généralement obtenue par collage.Furthermore, the hob according to DE-A-3227058 generally comprises several elements such as for example a hob, a frame and a housing. he it is necessary to provide a seal comparable to that described previously. This tightness is generally obtained by gluing.

Ces deux niveaux étanchéité étant réalisés par des dispositifs distincts, le montage s'avère délicat et le coût global de l'étanchéité est par le fait élevé.These two sealing levels being produced by devices separate, mounting is delicate and the overall cost of sealing is the high fact.

Afin de remédier à ces différents inconvénients, la présente invention a pour objet de simplifier le montage des différents éléments cités précédemment entre eux et de réduire le coût lié à étanchéité.In order to remedy these various drawbacks, the present object of the invention is to simplify the mounting of the various elements mentioned previously between them and reduce the cost related to sealing.

Pour atteindre ce but, la table de cuisson comporte les caractéristiques de la revendication 1.To achieve this goal, the hob has the features of claim 1.

  • la figure 7 représente une adaptation du joint où il recouvre la tête d'une vis.
    • The invention will be better understood and other characteristics will appear with the aid of the description below and of the accompanying drawings in which: all the figures show in section an example of an assembly process according to the invention with a few examples of variants. and where more particularly:
  • Figure 1 shows the general principle;

  • Figure 7 shows an adaptation of the seal where it covers the head of a screw.

    • Pour plus de simplicité, on utilisera, par la suite, les mêmes repères topologiques pour désigner les mêmes objets dans des figures différentes.For simplicity, we will use, thereafter, the same topological marks to designate the same objects in figures different.

    Le principe général de l'invention est décrit en s'appuyant sur la figure 1. Sur cette figure , au repère 1 est représenté un plan de cuisson par exemple en verre ou en vitrocéramique. Ce plan de cuisson 1 a par exemple la forme d'une plaque limitée par deux plans 2 et 3 parallèles. Le plan 2 forme la surface supérieure de la plaque et le plan 3 la surface inférieure. Cette plaque, généralement carrée ou rectangulaire est aussi limitée par quatre surfaces planes 4 perpendiculaires aux deux plans 2 et 3 et formant les cotés du plan de cuisson. Le plan de cuisson 1 est représenté en coupe partielle. Le plan de coupe est perpendiculaire aux surfaces 2, 3 et a un coté 4. Un cadre 5 encercle le plan de cuisson 1 en suivant les côtés 4. Le cadre 5 comporte une partie massive 6 limitée principalement par deux surfaces sensiblement planes, l'une 7 suit parallèlement les côtés 4 et en est proche, l'autre 8 est sensiblement dans le prolongement du plan 3. La partie massive 6 est également limitée par une surface 9 qui peut être quelconque et qui a par exemple une fonction esthétique. Sur la figure 1 elle est représentée par un arc de cercle délimité par les surfaces 7 et 8. Le cadre 5 comporte aussi deux rebords qui prolongent la partie massive 6 par exemple tangentiellement à la surface 9. Le premier rebord 10 vient en appui sur le plan 2 du plan de cuisson 1, le deuxième rebord 11 descend plus bas que le plan 3 du plan de cuisson 1. En coupe, les rebords 10 et 11 ont la forme de doigts. La table de cuisson comporte également un carter 12. Ce carter ferme le dessous de la table cuisson, il contient entre autre des éléments de chauffage par exemple radiant ou à induction. Le carter 12 peut être réalisé en plusieurs pièces mécaniques. En figure 1, seule est représentée la partie du carter en contact avec le plan de cuisson 1 et le cadre 5. Cette partie du carter 12 est par exemple un profilé dont la section représentée figure 1 a la forme d'une équerre comportant deux branches. Une première branche 13 est sensiblement parallèle au plan 3 du plan de cuisson 1 et à la surface 8 du cadre 5. Une deuxième branche 14 est perpendiculaire à la première branche et descend sous le plan 3 du plan de cuisson 1.The general principle of the invention is described by relying on the figure 1. In this figure, in reference 1 is represented a cooking plan by example in glass or glass ceramic. This hob 1 has for example the shape of a plate limited by two planes 2 and 3 parallel. Plan 2 forms the upper surface of the plate and plane 3 the lower surface. This plate, generally square or rectangular is also limited by four plane surfaces 4 perpendicular to the two planes 2 and 3 and forming the sides of the hob. Cooking surface 1 is shown in section partial. The cutting plane is perpendicular to surfaces 2, 3 and has a side 4. A frame 5 surrounds the hob 1 along the sides 4. The frame 5 has a massive part 6 limited mainly by two surfaces substantially flat, one 7 follows the sides 4 in parallel and is close thereto, the other 8 is substantially in the extension of the plane 3. The part massive 6 is also limited by a surface 9 which can be arbitrary and which for example has an aesthetic function. In figure 1 it is represented by an arc of a circle delimited by surfaces 7 and 8. The frame 5 also has two flanges which extend the massive part 6 for example tangentially to the surface 9. The first flange 10 bears on the plane 2 of cooking surface 1, the second edge 11 descends lower than the plane 3 of the cooking surface 1. In section, the edges 10 and 11 have the form of fingers. The hob also has a housing 12. This housing closes the underside of the cooktop, it contains, among other elements of radiant or induction heating, for example. The casing 12 can be produced in several mechanical parts. In Figure 1, only the part is represented of the housing in contact with the cooking surface 1 and the frame 5. This part of the casing 12 is for example a profile whose cross section shown in FIG. 1 has the shape of a square with two branches. A first branch 13 is substantially parallel to the plane 3 of the cooking surface 1 and to the surface 8 of the frame 5. A second branch 14 is perpendicular to the first branch and descends under plane 3 of cooking surface 1.

    Conformément à l'invention, deux niveaux d'étanchéité sont réalisés par un seul joint 15. Ce joint 15 est réalisé en matière souple par exemple à base de silicone afin de pallier les effets d'éventuels défauts de forme ou de positions des pièces avec lesquelles il est en contact.According to the invention, two levels of tightness are made by a single seal 15. This seal 15 is made of flexible material by example based on silicone in order to mitigate the effects of possible defects in shape or positions of the parts with which it is in contact.

    Un premier niveau concerne l'étanchéité de l'intérieur de la table de cuisson par rapport à l'extérieur. Plus précisément, il s'agit d'éviter que des particules solides ou liquides ne puissent pénétrer à l'intérieur de la table de cuisson. Ce premier niveau est obtenu au moyen d'une première zone 16 du joint 15. Cette zone est par exemple plane et est positionnée entre la première branche 13 de l'équerre du carter 12 et les deux surfaces 3 et 8, le plan 3 appartenant au plan de cuisson 1 et la surface 8 appartenant au cadre 5. Le joint est ensuite pressé pour assurer une barrière suffisante aux particules solides ou liquides en utilisant tout moyen mécanique adéquat indémontable comme par exemple le collage ou l'agrafage ou démontable comme par exemple à l'aide d'une ou plusieurs vis, d'un ou plusieurs clips.A first level concerns the tightness of the inside of the table cooking compared to the outside. More specifically, it is to avoid that solid or liquid particles cannot penetrate inside the Cooktop. This first level is obtained by means of a first zone 16 of the seal 15. This zone is for example flat and is positioned between the first branch 13 of the housing square 12 and the two surfaces 3 and 8, the plane 3 belonging to the cooking surface 1 and the surface 8 belonging to frame 5. The seal is then pressed to ensure a sufficient barrier to solid or liquid particles using any means adequate mechanical cannot be dismantled, for example gluing or stapling or removable, for example using one or more screw, one or more clips.

    Un deuxième niveau concerne l'étanchéité entre la table de cuisson et un support 17 sur lequel la table de cuisson est posée. Ce support 17 est par exemple le plan de travail d'une cuisine équipée. Le support 17 comporte par exemple une ouverture de dimensions voisines des dimensions séparant les surfaces planes 4 délimitant le plan de cuisson 1. Les dimensions de cette ouverture sont suffisantes pour laisser passer la deuxième branche 14 du carter 12. La première branche 13 du carter 12 vient quant à elle en appui sur la face supérieure 19 du plan de travail 17. Comme pour le premier niveau d'étanchéité, il s'agit d'éviter que des particules solides ou liquides ne puissent pénétrer entre la table de cuisson et le plan de travail 17. Pour assurer ce deuxième niveau, le joint 15 est prolongé entre la branche 13 de l'équerre du carter 12 et le rebord 11 du cadre 5. Ce prolongement porte le repère 18. Il déborde suffisamment la branche 13 et du rebord 11 pour pouvoir être pressé entre la table de cuisson et la face supérieure 19 du plan de travail 17 afin d'assurer une barrière suffisante aux particules solides ou liquides. Ce pressage est assuré par exemple par le simple poids de la table de cuisson ou par tout autre moyen décrit précédemment pour le premier niveau d'étanchéité.A second level concerns the seal between the table cooking and a support 17 on which the hob is placed. This support 17 is for example the worktop of an equipped kitchen. The support 17 comprises for example an opening of dimensions close to dimensions separating the flat surfaces 4 delimiting the cooking surface 1. The dimensions of this opening are sufficient to let the second branch 14 of the housing 12. The first branch 13 of the housing 12 comes to bear on the upper face 19 of the work surface 17. As with the first level of tightness, this is to prevent solid or liquid particles cannot enter between the hob and the work plan 17. To ensure this second level, the seal 15 is extended between branch 13 of the housing square 12 and the flange 11 of the box 5. This extension is marked 18. It extends beyond the branch 13 and rim 11 so that it can be pressed between the table cooking and the upper face 19 of the worktop 17 to ensure a sufficient barrier to solid or liquid particles. This pressing is ensured for example by the simple weight of the hob or by any other means described above for the first level of tightness.

    La figure 1 permet de visualiser un avantage lié à l'invention. En effet, l'assemblage de la table de cuisson peut être réalisé sans retournement. Un exemple d'ordre de montage est le suivant.

    • Pose du cadre 5, rebord 11 orienté vers le haut.
    • Mise en place du plan de cuisson dans le cadre 5, posé sur le rebord 10.
    • Mise en place du joint 15 recouvrant la surface 8 du cadre 5 et partiellement la surface 3 du plan de cuisson 1.
    • Mise en place du carter 12 recouvrant le joint 15.
    • Pressage du joint 15.
    Figure 1 shows a benefit related to the invention. Indeed, the assembly of the hob can be performed without turning. An example of an assembly order is as follows.
    • Installation of frame 5, edge 11 facing upwards.
    • Installation of the hob in frame 5, placed on the edge 10.
    • Installation of the seal 15 covering the surface 8 of the frame 5 and partially the surface 3 of the cooking surface 1.
    • Installation of the casing 12 covering the seal 15.
    • Pressing the seal 15.

    Un autre avantage lié à l'invention est obtenu lorsqu'on utilise des moyens de pressage du joint 15 tels que vis ou clips. Ces moyens permettent de s'affranchir du collage habituellement utilisé. Le collage a en effet l'inconvénient de perturber le cycle de fabrication de la table de cuisson à cause des temps de polymérisation ou séchage à respecter.Another advantage linked to the invention is obtained when using means for pressing the seal 15 such as screws or clips. These means allow to get rid of the collage usually used. The collage has effect the inconvenience of disrupting the manufacturing cycle of the hob because of the polymerization or drying times to be observed.

    Un autre avantage lié à l'invention est la possibilité de poser la table de cuisson directement sur le plan de travail et de presser le prolongement 18 du joint 15 avec le propre poids de la table de cuisson. Cela simplifie considérablement l'installation de la table de cuisson par exemple dans une cuisine domestique. On peut ainsi se passer de tous joints supplémentaires. Il reste néanmoins possible de fixer la table de cuisson sur le plan de travail au moyen d'un dispositif démontable tel que par exemple plusieurs vis.Another advantage linked to the invention is the possibility of laying the hob directly on the worktop and squeeze the extension 18 of seal 15 with the own weight of the hob. This considerably simplifies the installation of the hob by example in a domestic kitchen. We can do without all additional seals. However, it is still possible to fix the cooking on the work surface by means of a removable device such as for example several screws.

    La figure 2 représente une variante du procédé présenté figure 1 pour laquelle le rebord 10 du cadre 5 comporte à son extrémité une excroissance 30 se rapprochant du plan de cuisson 1. Cette excroissance a pour fonction de réaliser entre le cadre 5 et le plan de cuisson 1 une étanchéité supplémentaire amont au premier niveau d'étanchéité décrit en figure 1. Cette étanchéité supplémentaire fait principalement obstacle aux poussières.FIG. 2 represents a variant of the process presented in FIG. 1 for which the rim 10 of the frame 5 has at its end a protrusion 30 approaching the cooking surface 1. This protrusion has for the function of producing between the frame 5 and the hob 1 a additional sealing upstream at the first sealing level described in figure 1. This additional sealing mainly prevents dust.

    A la différence de la figure 1, la figure 3 représente le plan 3 du plan de cuisson 1 sensiblement décalé de la surface 8 du cadre 5. Le décalage est rattrapé par le joint 15 qui possède une épaisseur différente sous la surface 8. Cette forme particulière de joint trouve son utilité lorsqu'on souhaite utiliser un cadre 5 unique avec des plans de cuisson 1 d'épaisseur différente ou lorsqu'on souhaite utiliser un plan de cuisson 1 unique avec plusieurs cadres 5 de dimensions différentes. Pour répondre à ce besoin, les dimensions du joint 15 peuvent être adaptées. La figure 3 représente un joint plus épais sous le cadre 5 que sous le plan de cuisson 1, on peut bien entendu réaliser l'inverse, à savoir un joint plus épais sous le plan de cuisson 1 que sous le cadre 5 lorsque les dimensions du cadre 5 et du plan de cuisson 1 le nécessitent. De façon plus générale, il est possible de réaliser un joint 15 ayant une forme adaptée aux formes de toutes les pièces avec lesquelles il est en contact comme par exemple le plan de cuisson 1, le cadre 5, le carter 12, et le plan de travail 17.Unlike Figure 1, Figure 3 shows the plane 3 of the cooking surface 1 substantially offset from the surface 8 of the frame 5. The offset is taken up by joint 15 which has a different thickness under the surface 8. This particular form of joint finds its usefulness when wish to use a single frame 5 with 1 thick hobs different or when you want to use a single hob 1 with several frames 5 of different dimensions. To meet this need, the dimensions of the seal 15 can be adapted. Figure 3 shows a thicker seal under the frame 5 than under the hob 1, we can heard realize the opposite, namely a thicker joint under the plane of cooking 1 only under frame 5 when the dimensions of frame 5 and the plan 1 require it. More generally, it is possible to make a seal 15 having a shape adapted to the shapes of all the parts with which it is in contact, such as hob 1, the frame 5, the housing 12, and the worktop 17.

    La figure 4 reprend les différents éléments de la figure 1 en y ajoutant une vis 40 assurant le pressage du joint 15. L'axe de cette vis est perpendiculaire à la zone 16 du joint 15.

    La figure 7 reprend les différents éléments de la figure 1 en y ajoutant une vis 40 assurant le pressage du joint 15. L'axe de cette vis est perpendiculaire à la zone 16 du joint 15. Le corps de la vis 40 traverse un trou lisse percé dans la branche 13 de l'équerre du carter 12. La vis 40 est vissée dans un trou taraudé 43 réalisé dans le cadre 5. la vis 40 comporte une tête 41, cette tête 41 se situe en dessous de la branche 13 et y forme une proéminence. Le prolongement 18 du joint 15 s'étend sous la tête 41 de la vis 40. L'extrémité 70 du prolongement 18 vient en contact avec la branche 13. Sous la tête 41, le prolongement 18 comporte une double paroi au milieu de laquelle se situe un vide 71.Figure 7 shows the different elements of Figure 1 in y adding a screw 40 ensuring the pressing of the seal 15. The axis of this screw is perpendicular to the area 16 of the seal 15. The body of the screw 40 passes through a smooth hole drilled in branch 13 of the housing bracket 12. The screw 40 is screwed into a threaded hole 43 made in frame 5. the screw 40 has a head 41, this head 41 is located below the branch 13 and forms there a prominence. The extension 18 of the seal 15 extends under the head 41 of the screw 40. The end 70 of the extension 18 comes into contact with the branch 13. Under the head 41, the extension 18 has a double wall in the middle of which is a void 71.

    Les figures 3, 5, 6 et 7 présentent plusieurs aménagements du joint 15 donnés à titre d'exemple. Ce joint 15 peut être réalisé par divers modes de réalisation comme par exemple le moulage ou l'extrusion. Ces modes de réalisation offrent de grandes libertés de formes possibles qu'on peut utiliser par exemple pour s'adapter aux dimensions et aux formes des pièces entre lesquelles le joint 15 se situe ou pour adapter localement l'élasticité du joint. Plus particulièrement, les figures 5 et 6 présentent des joints comportant des lèvres 50 et 60 et/ou des bourrelets 61. Ces aménagements (lèvres ou dômes) constitue des exemples de formes améliorant l'étanchéité de l'assemblage. Les lèvres 50 et 60 et les bourrelets 61 ont été représentés par paire, il est bien entendu que leurs nombres n'est donné qu'à titre d'exemple.Figures 3, 5, 6 and 7 show several arrangements of the seal 15 given by way of example.
