Description

La présente invention se rapporte au domaine technique général des plaques et tables de cuisson et plus particulièrement au domaine concernant les plaques de cuisson posables sur un support quelconque, ou sur une table de travail.The present invention relates to the general technical field of hotplates and hobs and more particularly to the field of hotplates posable on any support, or on a work table.

La présente invention concerne un appareil chauffant comportant une plaque de cuisson du type vitrocéramique par exemple, agencée sur un boîtier support de structure particulière de manière à collecter et évacuer des liquides ou fluides déversés sur ladite plaque.The present invention relates to a heating device comprising a cooking plate of the glass ceramic type for example, arranged on a support housing of particular structure so as to collect and evacuate liquids or fluids spilled on said plate.

Il est déjà connu dans l'art antérieur d'étancher une plaque de cuisson du type table vitrocéramique avec son support en utilisant une couche de mastic silicone remplissant l'espace libre entre l'extrémité de la plaque de cuisson et une paroi du support.It is already known in the prior art to seal a cooking plate of the glass ceramic table type with its support using a layer of silicone sealant filling the free space between the end of the cooking plate and a wall of the support.

Il est également connu d'utiliser un jonc en aluminium pour fixer et serrer une plaque de cuisson sur son support. L'étanchéité de l'ensemble est réalisée par l'agencement d'un joint élastomère à l'interface de la plaque de cuisson et du support.It is also known to use an aluminum rod to fix and tighten a baking sheet on its support. The whole is sealed by the arrangement of an elastomeric seal at the interface of the hob and the support.

Il s'avère cependant que d'avoir recours à l'utilisation d'une couche de mastic silicone ou d'un joint élastomère n'est pas satisfaisant. En effet, l'agencement d'un joint sur le support d'une plaque de cuisson nécessite, outre l'emploi du joint comme pièce indépendante et supplémentaire, une mise en place délicate dudit joint. Il est par ailleurs nécessaire de procéder à une mise en place complexe d'une couche de mastic silicone pour obtenir une étanchéité parfaite d'une part et un aspect soigné d'autre part. Ces opérations se font en partie manuellement et sont par conséquent coûteuses. L'utilisation d'un joint élastomère est également à l'origine d'une augmentation du coût d'un tel appareil chauffant.However, it turns out that using a layer of silicone sealant or an elastomeric seal is not satisfactory. Indeed, the arrangement of a seal on the support of a cooking plate requires, in addition to the use of the seal as an independent and additional part, a delicate positioning of said seal. It is also necessary to carry out a complex installation of a layer of silicone sealant to obtain a perfect seal on the one hand and a neat appearance on the other hand. These operations are done partly manually and are therefore expensive. The use of an elastomeric seal is also at the origin of an increase in the cost of such a heating appliance.

L'objet assigné à l'invention vise en conséquence à remédier aux différents inconvénients énumérés précédemment et à fournir un appareil chauffant qui ne présente pas de problème d'étanchéité, de manière à maintenir différents organes tels que les éléments chauffants à l'abri de l'humidité.The object assigned to the invention therefore aims to remedy the various drawbacks listed above and to provide a heating device which does not present a leakage problem, so as to keep different organs such as the heating elements away from humidity.

Un autre objet de l'invention vise à fournir un appareil chauffant que l'on peut fabriquer en grande série sans avoir recours à des opérations de finition manuelles d'une part ou à la mise en place de joints d'autre part.Another object of the invention is to provide a heating appliance which can be mass produced without having to resort to manual finishing operations on the one hand or the installation of seals on the other hand.

Un objet supplémentaire de la présente invention vise bien évidemment à réduire le prix de revient d'un appareil chauffant conforme à l'invention.An additional object of the present invention obviously aims to reduce the cost price of a heating device according to the invention.

Les objets assignés à l'invention sont atteints à l'aide d'un appareil chauffant dans lequel sont agencés une plaque de cuisson, des éléments chauffants, un boîtier support, caractérisé en ce qu'il comporte un moyen de collecte de liquides au voisinage de l'interface entre le boîtier support et la plaque de cuisson.The objects assigned to the invention are achieved using a heating device in which are arranged a hob, heating elements, a support housing, characterized in that it comprises a means for collecting liquids in the vicinity of the interface between the support box and the hob.

Dans la description qui va suivre, il sera fait référence notamment à un appareil chauffant posable, comportant une plaque vitrocéramique. Il est évident que l'invention ne se limite pas à cet exemple particulier de réalisation. En effet, tout dispositif comportant une plaque de cuisson peut être concerné par l'objet de la présente invention.In the description which follows, reference will be made in particular to a posable heating appliance comprising a glass-ceramic plate. It is obvious that the invention is not limited to this particular example of embodiment. Indeed, any device comprising a cooking plate can be concerned with the object of the present invention.

La figure 1 montre une vue de dessus globale d'un appareil chauffant 15 conforme à l'invention. L'appareil chauffant 15 comporte une plaque de cuisson 1, un jonc 3, un boîtier support 2 ainsi que des éléments chauffants (non représentés aux figures) agencés dans le boîtier support 2.Figure 1 shows an overall top view of a heater 15 according to the invention. The heating appliance 15 comprises a cooking plate 1, a rod 3, a support housing 2 as well as heating elements (not shown in the figures) arranged in the support housing 2.

La plaque de cuisson 1 est préférentiellement une plaque vitrocéramique destinée à transmettre l'énergie thermique fournie par les éléments chauffants vers un récipient ou une poële posés sur ladite plaque de cuisson 1.The cooking plate 1 is preferably a glass-ceramic plate intended to transmit the thermal energy supplied by the heating elements to a container or a pan placed on said cooking plate 1.

Avantageusement, la plaque de cuisson 1 vitrocéramique est constituée sur sa surface inférieure, en regard des éléments chauffants et reposant sur le boîtier support 2, d'une surface comportant un bosselage pour favoriser le passage de liquides au niveau de l'interface entre ladite plaque de cuisson 1 et le boîtier support 2.Advantageously, the vitroceramic cooking plate 1 is constituted on its lower surface, facing the heating elements and resting on the support housing 2, of a surface comprising a boss to promote the passage of liquids at the interface between said plate 1 and the support box 2.

Selon une variante de réalisation de l'appareil chauffant 15 conforme à l'invention, la plaque de cuisson 1 est constituée d'un matériau du type métallique tel que du fer, de l'acier ou un alliage adapté à la fabrication de tables chauffantes.According to an alternative embodiment of the heating device 15 according to the invention, the cooking plate 1 is made of a material of the metallic type such as iron, steel or an alloy suitable for the production of heating tables.

La plaque de cuisson 1 constitue ainsi une plaque support sur laquelle est agencé un foyer chauffant du type foyer en fonte. La plaque de cuisson 1 peut également être réalisée en un matériau métallique émaillé ou inoxydable.The cooking plate 1 thus constitutes a support plate on which a heating hearth of the cast iron hearth type is arranged. The cooking plate 1 can also be made of an enameled or stainless metallic material.

Le boîtier support 2 est destiné à contenir les éléments chauffants d'une part et à supporter la plaque de cuisson 1 d'autre part.The support box 2 is intended to contain the heating elements on the one hand and to support the cooking plate 1 on the other hand.

Le boîtier support 2 est réalisé par moulage d'un matériau plastique du type polyester ou polyamide, indépendamment du matériau constitutif de la plaque de cuisson 1, et présente une forme de préférence carrée ou rectangulaire obtenue par moulage.The support housing 2 is produced by molding a plastic material of the polyester or polyamide type, independently of the material constituting the hob 1, and has a preferably square or rectangular shape obtained by molding.

Le boîtier support 2 présente un volume libre interne servant à contenir les éléments chauffants ainsi qu'une forme périphérique profilée particulière.The support box 2 has an internal free volume serving to contain the heating elements as well as a particular profiled peripheral shape.

La figure 2 montre selon une vue en coupe un cadre externe 2c du boîtier support 2, délimitant les bords de l'appareil chauffant 15. Le cadre externe 2c comporte également un tableau de commande 8 de l'appareil chauffant 15.FIG. 2 shows, in a sectional view, an external frame 2c of the support housing 2, delimiting the edges of the heating device 15. The external frame 2c also includes a control panel 8 of the heating device 15.

Le boîtier support 2 présente également une fente 2b dont la fonction est de positionner et fixer le jonc 3. La fente 2b est ainsi délimitée par une surface d'appui 2a verticale et par une barre de positionnement 7 verticale, sur toute la périphérie du boîtier support 2.The support box 2 also has a slot 2b whose function is to position and fix the rod 3. The slot 2b is thus delimited by a vertical support surface 2a and by a vertical positioning bar 7, over the entire periphery of the box support 2.

En outre, le boîtier support 2 présente une zone d'appui 6 périphérique et sensiblement horizontale sur laquelle repose la plaque de cuisson 1. La zone d'appui 6 débouche, vers l'intérieur du boîtier support 2, sur une gorge 4 périphérique dans laquelle sont ménagés des trous d'écoulement 5. Ces derniers débouchent sur l'extérieur du boîtier support 2 et sont répartis le long de la gorge 4. Cette dernière s'étend au moins partiellement au voisinage de la périphérie de la zone d'appui 6 pour la plaque de cuisson 1.In addition, the support box 2 has a peripheral and substantially horizontal support zone 6 on which the cooking plate 1 rests. The support zone 6 opens, towards the inside of the support box 2, onto a groove 4 peripheral in which are provided drain holes 5. These open onto the outside of the support housing 2 and are distributed along the groove 4. The latter extends at least partially in the vicinity of the periphery of the zone d support 6 for cooking plate 1.

La gorge 4 est donc délimitée d'une part, par la zone d'appui 6, et d'autre part par une paroi de gorge interne 4b dont la hauteur est légèrement inférieure au plan d'extension de la zone d'appui 6. La paroi de gorge interne 4b définit également le volume libre interne du boîtier support 2, inaccessible à des liquides déversés sur la plaque de cuisson 1.The groove 4 is therefore delimited on the one hand, by the support zone 6, and on the other hand by an internal groove wall 4b whose height is slightly less than the extension plane of the support zone 6. The internal groove wall 4b also defines the internal free volume of the support housing 2, inaccessible to liquids spilled on the cooking plate 1.

Le volume libre ainsi défini permet d'y loger des foyers chauffants électriques ou à gaz.The free volume thus defined makes it possible to house electric or gas heated fireplaces.

Ainsi l'appareil chauffant 15 conforme à l'invention comporte un moyen de collecte de liquides au voisinage de l'interface entre le boîtier support 2 et la plaque de cuisson 1. Le moyen de collecte est donc constitué de la gorge 4 ménagée dans le boîtier support 2.Thus the heating device 15 according to the invention comprises a means for collecting liquids in the vicinity of the interface between the support box 2 and the cooking plate 1. The collecting means therefore consists of the groove 4 formed in the support box 2.

L'appareil chauffant 15 comporte en outre des moyens d'évacuation des liquides collectés, réalisés par au moins un trou d'écoulement 5 communiquant avec le moyen de collecte.The heating appliance 15 also comprises means for evacuating the collected liquids, produced by at least one flow hole 5 communicating with the collecting means.

Le jonc 3 de préférence en aluminium, et se divisant en quatre parties identiques pour faciliter son montage, est constitué d'une lame 3d recouvrant et s'appuyant sur une portion périphérique de la plaque de cuisson 1, ainsi que sur une portion périphérique du boîtier support 2. Le jonc 3 est par ailleurs constitué de deux lèvres 3b parallèles, agencées perpendiculairement par rapport au plan d'extension de la lame 3d et s'étendant le long du jonc 3.The rod 3 preferably made of aluminum, and dividing into four identical parts to facilitate its assembly, consists of a 3d blade covering and resting on a peripheral portion of the cooking plate 1, as well as on a peripheral portion of the support housing 2. The rod 3 also consists of two parallel lips 3b, arranged perpendicularly to the plane of extension of the blade 3d and extending along the rod 3.

L'écart entre les deux lèvres 3b, de même que la hauteur des lèvres 3b sont choisis en fonction des dimensions de la fente 2b de manière à ce que le boîtier support 2 exerce une légère pression sur lesdites lèvres 3b lorsque le jonc 3 est mis en place. Le jonc 3 sert ainsi à fixer la plaque de cuisson 1 sur le boîtier support 2. Le jonc 3 présente avantageusement un chanfrein 3a sur sa surface supérieure de manière à ne pas exposer d'angle saillant sur la surface extrême et supérieure de l'appareil chauffant 15.The distance between the two lips 3b, as well as the height lips 3b are chosen as a function of the dimensions of the slot 2b so that the support housing 2 exerts a slight pressure on said lips 3b when the rod 3 is put in place. The rod 3 thus serves to fix the cooking plate 1 to the support housing 2. The rod 3 advantageously has a chamfer 3a on its upper surface so as not to expose a projecting angle on the end and upper surface of the appliance. heating 15.

La figure 2 montre également des perçages 2d ménagés au travers du fond de la fente 2b. Les perçages 2d permettent ainsi à fixer le jonc 3 sur le boîtier support 2 par l'intermédiaire de vis 10 dont le diamètre est judicieusement choisi pour permettre de visser lesdites vis 10 entre les lèvres 3b en les déformant légèrement de manière à former un ensemble solidaire et rigide mécaniquement. Tout autre moyen de fixation du jonc 3 sur le boîtier support 2 peut également convenir, comme par exemple le collage ou le clipsage.Figure 2 also shows holes 2d formed through the bottom of the slot 2b. The holes 2d thus make it possible to fix the rod 3 on the support housing 2 by means of screws 10, the diameter of which is judiciously chosen to allow said screws 10 to be screwed between the lips 3b by slightly deforming them so as to form an integral assembly. and mechanically rigid. Any other means of fixing the rod 3 on the support housing 2 may also be suitable, such as for example bonding or clipping.

Selon une variante de réalisation conforme à l'invention, les vis 10 de fixation sont supprimées pour fournir un appareil chauffant 15 disposant d'une plaque de cuisson 1 amovible.According to an alternative embodiment according to the invention, the fixing screws 10 are omitted to provide a heating device 15 having a removable cooking plate 1.

Selon une autre variante de réalisation d'un appareil chauffant 15 conforme à l'invention, la structure du boîtier support 2 peut être simplifiée de manière à supprimer les joncs 3 sur toute la périphérie dudit appareil chauffant 15. Ce dernier comporte ainsi une plaque de cuisson 1 amovible, uniquement posée sur le boîtier support 2.According to another alternative embodiment of a heating device 15 according to the invention, the structure of the support housing 2 can be simplified so as to eliminate the rods 3 over the entire periphery of said heating device 15. The latter thus comprises a plate cooking 1 removable, only placed on the support box 2.

La figure 3 montre par une vue en perspective une partie du boîtier support 2 dont la zone d'appui 6 présente au moins une rigole 6a pour l'écoulement de liquides vers la gorge 4.FIG. 3 shows a perspective view of a part of the support housing 2, the support area 6 of which has at least one channel 6a for the flow of liquids towards the groove 4.

En outre, la barre de positionnement 7 périphérique présente des nervures 7a contre lesquelles est disposée la plaque de cuisson 1 de manière à ménager un espace d'écoulement 7b entre la plaque de cuisson 1 et la barre de positionnement 7.In addition, the peripheral positioning bar 7 has ribs 7a against which the cooking plate 1 is arranged so as to provide a space 7b between the hob 1 and the positioning bar 7.

Selon une variante de réalisation de l'appareil chauffant 15 conforme à l'invention et représenté à la figure 4, la plaque de cuisson 1 est une plaque métallique emboutie de manière à présenter symétriquement sur au moins une partie de sa périphérie une calotte la reposant sur la zone d'appui 6. Le maintien de ladite plaque de cuisson 1 est également réalisé par le jonc 3.According to an alternative embodiment of the heating device 15 according to the invention and shown in Figure 4, the cooking plate 1 is a stamped metal plate so as to present symmetrically on at least part of its periphery a cap resting it on the support zone 6. The maintenance of said cooking plate 1 is also achieved by the rod 3.

Selon une autre variante de réalisation de l'appareil chauffant conforme à l'invention et représenté à la figure 5, la plaque de cuisson 1 n'est pas, ou très peu, emboutie, et elle ne repose pas directement sur la zone d'appui 6. La plaque de cuisson 1 se trouve maintenue entre le jonc 3 et des entretoises 12. Ces dernières sont des pièces de forme sensiblement en T qui viennent se loger dans la gorge 4 en n'obstruant pas, toutefois, la totalité de ladite gorge 4. Les entretoises 12 sont préférentiellement réalisées en un matériau réfractaire ou isolant thermiquement du type résine phénolique thermodurcissable. Le nombre de ces entretoises est variable suivant la taille des plaques de cuisson 1.According to another alternative embodiment of the heating device according to the invention and shown in FIG. 5, the cooking plate 1 is not, or very little, pressed, and it does not rest directly on the zone of support 6. The cooking plate 1 is held between the rod 3 and spacers 12. The latter are substantially T-shaped parts which are received in the groove 4 while not obstructing all of said groove 4. The spacers 12 are preferably made of a refractory or thermally insulating material of the phenolic thermosetting resin type. The number of these spacers varies according to the size of the cooking plates 1.

L'appareil chauffant 15 conforme à l'invention s'adapte parfaitement à l'utilisation de foyers chauffants en fonte où les éléments chauffants se trouvent noyés dans lesdits foyers.The heating device 15 according to the invention is perfectly suited to the use of cast iron heating fireplaces where the heating elements are embedded in said fireplaces.

La plaque de cuisson 1 présente dans ce cas de figure un découpage pour y loger les foyers chauffants. Ce mode de réalisation convient évidemment pour une plaque de cuisson 1 métallique ou vitrocéramique.In this case, the cooking plate 1 has a cutout for accommodating the heated fireplaces. This embodiment is obviously suitable for a metal or ceramic hob 1.

Les foyers chauffants électriques en fonte conviennent particulièrement bien à l'utilisation d'une plaque de cuisson 1 métallique.Electric cast iron electric fireplaces are particularly suitable for the use of a metal cooking plate 1.

Selon une variante de réalisation de l'appareil chauffant 15 conforme à l'invention, les foyers chauffants à gaz peuvent être utilisés en association avec une plaque de cuisson 1 métallique ou vitrocéramique.According to an alternative embodiment of the heating device 15 according to the invention, the gas heating hearths can be used in combination with a metal or ceramic hob 1.

D'une manière avantageuse, l'appareil chauffant 15 conforme à l'invention présente une plaque de cuisson 1 vitrocéramique, dont le coefficient de dilatation est quasiment nul en dessous d'une température de l'ordre de 600° et dont le matériau constitutif est perméable aux rayonnements infrarouges, associée à des éléments chauffants radiants.Advantageously, the heating device 15 according to the invention has a ceramic glass hob 1, the coefficient of expansion of which is almost zero below a temperature of the order of 600 ° and the constituent material of which is permeable to infrared radiation, associated with radiant heating elements.

Dans un mode de réalisation supplémentaire de l'invention, on peut envisager de réaliser un appareil chauffant 15 de forme générale circulaire.In a further embodiment of the invention, it is possible to envisage producing a heating device 15 of generally circular shape.

Un autre mode de réalisation peut consister à juxtaposer plusieurs foyers chauffants dans le même appareil chauffant 15 en adaptant le boîtier support 2.Another embodiment may consist in juxtaposing several heating zones in the same heating appliance 15 by adapting the support box 2.

Selon une variante additionnelle de l'appareil chauffant 15 conforme à l'invention on peut envisager d'appliquer l'objet de la présente invention à des tables de cuisson comportant des plaques de cuisson 1 encastrables, en prévoyant un réservoir facilement accessible pour l'utilisateur et en communication avec les moyens de collecte et d'évacuation.According to an additional variant of the heating device 15 according to the invention, it is possible to envisage applying the object of the present invention to cooktops comprising built-in cooking plates 1, by providing a tank easily accessible for user and in communication with the collection and disposal means.

Le réservoir aura pour fonction de recueillir et stocker les liquides déversés sur la plaque de cuisson 1 et drainés ou conduits vers ledit réservoir par l'intermédiaire de la gorge 4.The function of the reservoir will be to collect and store the liquids poured onto the cooking plate 1 and drained or led to said reservoir via the groove 4.

La gorge 4 peut également être rapportée au boîtier support 2 selon une variante de réalisation de l'appareil chauffant 15.The groove 4 can also be attached to the support box 2 according to an alternative embodiment of the heating device 15.

Selon un mode préférentiel de fonctionnement d'un appareil chauffant 15 conforme à l'invention, le système de collecte et d'écoulement est conçu pour évacuer les liquides déversés malencontreusement sur la plaque de cuisson 1 et s'infiltrant dans le boîtier support 2 au niveau des interfaces entre la plaque de cuisson 1 et le jonc 3 d'une part et entre la plaque de cuisson 1 et le boîtier support 2 d'autre part.According to a preferred mode of operation of a heating device 15 according to the invention, the collection and flow system is designed to evacuate the liquids inadvertently spilled on the cooking plate 1 and infiltrating into the support housing 2 at level of the interfaces between the cooking plate 1 and the rod 3 on the one hand and between the cooking plate 1 and the support housing 2 on the other hand.

Il s'avère, en effet, que l'étanchéité n'est pas parfaite, et plus spécialement au niveau des interfaces entre les différentes pièces constituantes du jonc 3. La gorge 4 permet ainsi d'évacuer les liquides infiltrés vers l'extérieur du boîtier support 2.It turns out, in fact, that the seal is not perfect, and more particularly at the interfaces between the various constituent parts of the rod 3. The groove 4 thus makes it possible to evacuate the infiltrated liquids towards the outside of the support box 2.

Un avantage de la présente invention réside dans la suppression d'un joint ou d'une autre pièce d'étanchéité. L'assemblage d'un appareil chauffant 15 conforme à l'invention se trouve ainsi facilité tout en n'affectant nullement son bon fonctionnement ou la sécurité d'utilisation.An advantage of the present invention lies in the elimination of a seal or other sealing part. The assembly of a heating device 15 according to the invention is thus facilitated while in no way affecting its proper functioning or safety of use.

Un autre avantage est lié à la réduction du coût de fabrication de tels appareils chauffants 15 non étanches.Another advantage is linked to the reduction in the manufacturing cost of such non-waterproof heating devices.

Un avantage supplémentaire réside dans la fabrication d'un boîtier support 2 particulier qui permet de contrôler l'infiltration des liquides déversés sur la plaque de cuisson 1.An additional advantage lies in the manufacture of a particular support box 2 which makes it possible to control the infiltration of the liquids spilled on the cooking plate 1.

Un avantage additionnel est atteint en fournissant un appareil chauffant 15 conforme à l'invention qui peut être facilement démonté et remonté sans nuire à l'étanchéité du volume interne du boîtier support 2.An additional advantage is achieved by providing a heating device 15 according to the invention which can be easily disassembled and reassembled without affecting the tightness of the internal volume of the support housing 2.
