Description

La présente invention est relative à un appareil de cuisson comportant une plaque supérieure essentiellement plane et au moins un foyer de cuisson.The present invention relates to a cooking appliance comprising an essentially flat upper plate and at least one cooking hearth.

Dans le domaine des équipements destinés à un usage domestique, les évolutions des appareils utilisés dans la cuisine, imposées par des contraintes esthétiques et/ou techniques, ont été constantes et importantes au cours des dernières années.In the field of equipment intended for domestic use, the changes in appliances used in the kitchen, imposed by constraints aesthetic and / or technical, have been constant and important during last years.

En particulier, la conception des appareils de cuisson a subi de nombreuses modifications.In particular, the design of cooking appliances has undergone many modifications.

Ainsi, il est connu depuis fort longtemps des cuisinières en tôle émaillée utilisant comme foyers de cuisson des brûleurs à gaz naturel ou GPL. Les avantages procurés par de telles cuisinières, liés directement à la nature des foyers de cuisson précités, sont bien appréhendés : souplesse d'utilisation, faible inertie thermique, visibilité immédiate des réglages de la puissance de chauffe. Les inconvénients de ces cuisinières le sont également comme, par exemple, la présence d'une grille métallique en forme de cadre dont le nettoyage fréquent est nécessaire.Thus, it has been known for a long time for enameled sheet cookers using natural gas or LPG burners as cooking stoves. The advantages provided by such cookers, directly linked to the nature of the aforementioned cooking zones, are well understood: flexibility of use, low thermal inertia, immediate visibility of the power settings heated. The disadvantages of these stoves are also as, for example, the presence of a metal grid in the form of a frame, the frequent cleaning is necessary.

Qui plus est, l'esthétique de ces cuisinières parait de plus en plus démodée, même avec l'utilisation récente d'une plaque en verre moulé sur laquelle sont posés les brûleurs à gaz.What's more, the aesthetics of these cookers seem more and more old-fashioned, even with the recent use of a molded glass plate on which the gas burners are installed.

Il est connu également depuis longtemps des tables de cuisson communément appelées « plaques électriques » utilisant comme foyers de cuisson des résistances électriques disposées sous des plaques circulaires métalliques. Ces tables de cuisson présentent l'avantage essentiel de ne plus avoir de grilles métalliques puisque les ustensiles de cuisson sont posés directement sur les plaques chauffantes précitées.Cooktops have also been known for a long time commonly called "electric plates" using as fireplaces cooking of electric resistances arranged under circular plates metallic. These cooktops have the essential advantage of no longer have metal grates since the cooking utensils are placed directly on the aforementioned hot plates.

Concomitamment à l'apparition du concept de cuisine intégrée, un changement important a été apporté dans les tables de cuisson. Ce changement a consisté à utiliser comme plaques de cuisson des plaques en matériau vitrocéramique.Concomitantly with the appearance of the concept of integrated kitchen, a a significant change has been made to the cooktops. This change consisted in using baking trays as glass ceramic material.

Ces plaques, désormais largement répandues, bénéficient, entre autre, de deux avantages notables, à savoir la facilité de nettoyage (du fait que la surface d'une plaque vitrocéramique est essentiellement plane) et un aspect extérieur résolument nouveau conférant une allure plus moderne.These plates, now widely used, benefit, among other things, two notable advantages, namely the ease of cleaning (the fact that the surface of a ceramic hob is essentially flat) and an aspect resolutely new exterior giving a more modern look.

En outre, ces plaques de cuisson en matériau vitrocéramique ont été associées à de nouveaux foyers de cuisson tels que les lampes halogènes et les foyers à induction.In addition, these ceramic glass hobs have been associated with new cooking stoves such as halogen lamps and induction fireplaces.

Parallèlement aux modifications précitées, apportées aux appareils de cuisson, la conception des ustensiles de cuisson a également subi de nombreuses modifications.In addition to the aforementioned modifications to the cooking, the design of the cookware has also undergone many modifications.

En particulier, les récipients de cuisson du type poêle ou casserole, bien qu'ayant conservé leur fonction première, à savoir réchauffer et/ou cuire les aliments qu'ils contiennent, ont vu leur aspect extérieur et leur structure évoluer considérablement.In particular, cooking vessels of the pan or saucepan type, although that having retained their primary function, namely reheating and / or cooking foods they contain, have seen their external appearance and structure evolve considerably.

Une partie de ces modifications a été imposée uniquement par des contraintes d'ordre esthétique (couleur, motif décoratif).Some of these changes were imposed only by aesthetic constraints (color, decorative pattern).

Une autre partie de ces modifications est à relier au fait que les foyers de cuisson ont également évolué tant par leurs dimensions (dimensions définissant la partie active de chauffe) que par leur nature (foyers à lampes halogènes, foyers à induction).Another part of these modifications has to do with the fact that homes have also evolved both by their dimensions (dimensions defining the active heating part) only by their nature (lamp hearths halogen, induction fireplaces).

Par exemple, il a été développé des casseroles ou poêles en matériau ferromagnétique afin qu'elles puissent être adaptées aux foyers à induction.For example, pots or pans have been developed from material ferromagnetic so that they can be adapted to induction fireplaces.

Cependant, il existe à ce jour un besoin pour améliorer l'adéquation entre d'une part les parties des appareils de cuisson autres que les foyers de cuisson eux-mêmes (élément chauffant radiant ou halogène, brûleur à gaz, inducteur) et, d'autre part les récipients de cuisson.However, to date there is a need to improve the adequacy between on the one hand parts of cooking appliances other than fireplaces cooking themselves (radiant or halogen heating element, gas burner, inductor) and, on the other hand, the cooking vessels.

En effet, à l'usage, une adéquation imparfaite peut amener divers inconvénients. Indeed, in use, an imperfect adequacy can lead to various disadvantages.

Dans le cas particulier de tables de cuisson, l'utilisation de récipients spécifiques, par exemple de grandes dimensions et/ou ayant un état de surface particulier, peut s'avérer délicate sur des plaques de cuisson en vitrocéramique.In the particular case of cooktops, the use of cookware specific, for example of large dimensions and / or having a surface finish can be tricky on hotplates in vitroceramic.

Ainsi, il peut s'avérer difficile de centrer avec précision les récipients, notamment de grandes dimensions, au droit des foyers de cuisson sous-jacents à la plaque de telle sorte que leur fond n'est pas nécessairement chauffé de manière homogène sur toute leur surface.This can make it difficult to center containers precisely, particularly large, in line with the underlying cooking zones to the plate so that their bottom is not necessarily homogeneously heated over their entire surface.

De même, du fait que les récipients ne sont pas nécessairement limités dans leur déplacement relatif par rapport à la plaque, c'est-à-dire qu'ils ne sont pas cantonnés dans une zone précise de celle-ci, ils peuvent créer des rayures superficielles, le cas échéant préjudiciables à la résistance mécanique de la plaque. D'un point de vue sécurité, cela peut parfois s'avérer dangereux dans la mesure où des personnes non averties, par exemple des enfants, manipulant ces mêmes récipients chauds peuvent, sans effort excessif, les faire glisser sur la plaque et en final, les faire tomber de la table de cuisson concernée.Likewise, since the containers are not necessarily limited in their relative displacement with respect to the plate, that is to say that they are not not confined to a specific area thereof, they may create scratches superficial, if any detrimental to the mechanical strength of the plate. From a security point of view, this can sometimes be dangerous in the extent to which unsophisticated persons, for example children, manipulating these same hot containers can, without excessive effort, slide them onto the plate and finally, drop them from the hob concerned.

Le but de l'invention est alors de pallier aux inconvénients précités et de proposer notamment un appareil de cuisson à usage domestique qui permette de positionner avec suffisamment de précision tous récipients de cuisson existants tout en limitant leur déplacement par une personne non avertie.The object of the invention is then to overcome the aforementioned drawbacks and to offer in particular a cooking appliance for domestic use which allows to position all cooking vessels with sufficient precision existing while limiting their movement by an uninformed person.

Un autre but de l'invention est de proposer un appareil de cuisson à usage domestique qui permette de s'affranchir de l'utilisation d'un récipient de cuisson.Another object of the invention is to provide a cooking appliance for domestic use which eliminates the use of a container cooking.

Ces buts sont atteints selon l'invention par un appareil de cuisson comportant au moins une plaque supérieure essentiellement plane et au moins un foyer de cuisson caractérisé par le fait que ladite plaque comporte au moins une concavité sous laquelle est placé ledit foyer de cuisson.These objects are achieved according to the invention by a cooking appliance having at least one substantially planar top plate and at least a cooking hearth characterized in that said plate comprises at least a concavity under which said cooking hearth is placed.

On précise que, dans le cadre de l'invention, il faut comprendre par l'expression « foyer de cuisson», tous moyens de chauffage tels qu'un élément radiant ou un brûleur à gaz et/ou tous moyens concourant au chauffage tels qu'un inducteur concourant à un chauffage par induction.It is specified that, within the framework of the invention, it is necessary to understand by the expression “cooking hearth”, any means of heating such as a radiant element or a gas burner and / or any other means contributing to heating such as an inductor contributing to an induction heating.

Selon une caractéristique avantageuse de l'invention, le foyer de cuisson est un élément chauffant. Cet élément chauffant peut être radiant ou halogène.According to an advantageous characteristic of the invention, the cooking hearth is a heating element. This heating element can be radiant or halogen.

Le terme « radiant » est à comprendre comme étant constitué d'une résistance électrique.The term "radiant" should be understood as consisting of a electrical resistance.

Celle-ci peut être sous la forme d'un fil métallique conducteur. Elle peut être également sous la forme d'une couche conductrice de résistivité adéquate telle que celle décrite dans le Certificat d'Utilité FR/U 2 744 116. Le choix d'une telle forme peut être avantageux lorsqu'il est préférable que l'appareil de cuisson selon l'invention conserve un encombrement comparable à celui d'un appareil de cuisson de même type selon l'état de l'art, c'est-à-dire un appareil de cuisson ne comprenant pas de concavité conforme à l'invention.This can be in the form of a conductive metal wire. She can also be in the form of a conductive layer of adequate resistivity such as that described in the Certificate of Utility FR / U 2 744 116. The choice of such a shape can be advantageous when it is preferable that the cooking according to the invention retains a space comparable to that of a cooking appliance of the same type according to the state of the art, i.e. an appliance cooking not comprising a concavity according to the invention.

Cela peut être notamment le cas dans les configurations où la concavité présente une profondeur non négligeable.This can be particularly the case in configurations where the concavity has a significant depth.

De préférence, l'élément chauffant selon l'invention est calibré à une température maximale de l'ordre de 450°C. Cela permet d'effectuer la cuisson directe de tous types d'aliments dans la concavité conforme à l'invention sans risque de surchauffe excessive.Preferably, the heating element according to the invention is calibrated at a maximum temperature of the order of 450 ° C. This allows cooking direct of all types of food in the concavity according to the invention without risk of excessive overheating.

Il est également possible de coupler l'élément chauffant à deux limiteurs de température dont le déclenchement est réalisé à une température maximale de 400°C et 580°C, ces températures étant entendues comme étant celles établies à la surface de concavité.It is also possible to couple the heating element with two limiters temperature triggered at maximum temperature 400 ° C and 580 ° C, these temperatures being understood as those established at the concavity surface.

L'utilisateur peut, dans cette configuration, au choix soit réaliser la cuisson directe des aliments, soit la réaliser par l'intermédiaire d'ustensiles de cuisson classiques.The user can, in this configuration, either choose to carry out the direct cooking of food, either by using cooking utensils classic cooking.

Pour réguler la puissance de chauffe de l'élément chauffant, il est préférable de le faire par un thermostat fonctionnant à partir de la mesure de la température entre la plaque et le foyer de cuisson considéré. On évite ainsi l'emploi d'un doseur d'énergie qui impose un pourcentage de temps entre l'état de marche et l'arrêt.To regulate the heating power of the heating element, it is better to do it by a thermostat operating from the measurement of the temperature between the hob and the cooking hearth considered. We thus avoid the use of an energy metering device which imposes a percentage of time between running and stopping state.

Comme agencement préféré, l'élément chauffant présente avantageusement une forme annulaire et est placé en partie périphérique sous la concavité.As a preferred arrangement, the heating element has advantageously an annular shape and is placed partially peripheral under concavity.

Selon une caractéristique avantageuse de l'invention, la plaque peut être en matériau vitrocéramique. According to an advantageous characteristic of the invention, the plate can be glass-ceramic material.

Selon une autre caractéristique avantageuse de l'invention, la concavité elle-même est en matériau vitrocéramique.According to another advantageous characteristic of the invention, the concavity itself is made of glass ceramic material.

Il peut alors s'agir d'une plaque de cuisson vitrocéramique dont l'aspect est en harmonie avec le mobilier de cuisine telle que celle décrite dans la demande de brevet internationale WO 98/01676.It can then be a ceramic hob whose appearance is in harmony with kitchen furniture such as that described in the international patent application WO 98/01676.

De manière avantageuse, la plaque conforme à l'invention peut comporter en outre au moins une ouverture dans laquelle est inséré un brûleur à gaz de type atmosphérique et/ou au moins une zone de chauffe plane sous laquelle est placé un autre foyer de cuisson, tel qu'un élément chauffant ou un foyer à induction.Advantageously, the plate according to the invention can additionally have at least one opening into which a burner is inserted gas type atmospheric and / or at least one flat heating zone under which is placed another cooking zone, such as a heating element or a induction fireplace.

Selon cette configuration, l'appareil de cuisson selon l'invention est mixte car il comprend au moins deux sources de chaleur différentes par transfert direct et indirect de celle-ci.According to this configuration, the cooking appliance according to the invention is mixed because it includes at least two different heat sources per direct and indirect transfer thereof.

Une telle configuration permet à l'utilisateur de cuire et/ou réchauffer les aliments à souhait, notamment en tenant compte de certains critères, tels que la nature des aliments, éventuellement le type de récipient(s) mis à sa disposition.Such a configuration allows the user to cook and / or reheat the foods as desired, especially taking into account certain criteria, such as the nature of the food, possibly the type of container (s) placed at its disposition.

Selon cette même configuration, la plaque est constituée d'au moins deux modules juxtaposés, l'un des deux modules comportant au moins une concavité, l'autre comportant au moins une ouverture et/ou au moins une zone de chauffe plane. Cette configuration modulaire de la plaque est très avantageuse, plus particulièrement dans le cas où l'appareil de cuisson constitue une table de cuisson intégrée au mobilier de cuisine.According to this same configuration, the plate consists of at least two juxtaposed modules, one of the two modules comprising at least one concavity, the other comprising at least one opening and / or at least one zone flat heating. This modular configuration of the plate is very advantageous, more particularly in the case where the cooking appliance constitutes a hob integrated into the kitchen furniture.

En effet, dès la conception de la cuisine dite « intégrée », l'utilisateur final peut faire des choix à plusieurs niveaux.In fact, from the design of the so-called “integrated” kitchen, the user final can make choices on several levels.

Outre le choix du mobilier désiré et de son agencement, il peut désormais choisir la nature des foyers de cuisson qui composent la table de cuisson et la manière dont ils sont agencés dans cette dernière.In addition to the choice of furniture desired and its arrangement, it can now choose the nature of the cooking zones that make up the hob cooking and the way they are arranged in it.

De préférence, les modules précités sont assemblés entre eux par un dispositif mécanique évitant les infiltrations de toutes les particules liquides et/ou solides susceptibles d'être présentes sur chacun des modules.Preferably, the aforementioned modules are assembled together by a mechanical device preventing infiltration of all liquid particles and / or solids likely to be present on each of the modules.

Ce dispositif est avantageusement un joint de préférence résistant à haute température et étanche, du type joint en silicone. This device is advantageously a seal preferably resistant to high temperature and waterproof, silicone seal type.

Pour ce qui est de la liaison de la concavité à la plaque, deux alternatives peuvent être envisagées : la concavité peut être amovible ou intégrée à la plaque.As regards the connection of the concavity to the plate, two alternatives can be considered: the concavity can be removable or integrated into the plate.

La première alternative peut être choisie, par exemple lorsque les aliments destinés à être cuits et/ou réchauffés dans la concavité selon l'invention sont plutôt de type liquide.The first alternative can be chosen, for example when the food intended to be cooked and / or reheated in the concavity according to the invention are rather of the liquid type.

L'homme de l'art veillera, selon cette alternative, à assurer, une fois la concavité ôtée de la plaque, notamment une étanchéité, ainsi qu'une isolation électrique satisfaisantes en termes de sécurité, plus particulièrement dans le respect des normes relatives aux appareils électrodomestiques en vigueur.Those skilled in the art will take care, according to this alternative, to ensure, once the concavity removed from the plate, in particular a seal, as well as insulation satisfactory in terms of safety, especially in the compliance with the standards relating to household electrical appliances in force.

De préférence, la concavité conforme à l'invention comporte un fond plat, avantageusement parallèle au plan de la plaque. Il est ainsi plus commode de placer un récipient de cuisson dans la concavité lorsqu'il est préférable de le faire.Preferably, the concavity according to the invention comprises a bottom flat, advantageously parallel to the plane of the plate. It is thus more convenient place a cooking container in the concavity when it is best to make.

Ce fond plat peut être avantageusement circulaire. Un tel fond a l'avantage de ne présenter aucune arête vive nuisible à la facilité de nettoyage de la concavité.This flat bottom can advantageously be circular. Such a background has the advantage of having no sharp edges detrimental to the ease of cleaning concavity.

De préférence, ce fond plat circulaire a un diamètre compris entre 100 mm et 400 mm. Une telle gamme permet l'utilisation possible de tous les standards de récipients de cuisson existants.Preferably, this circular flat bottom has a diameter of between 100 mm and 400 mm. Such a range allows the possible use of all existing cooking vessel standards.

Selon une caractéristique additionnelle, le fond plat peut présenter une transmission dans les longueurs d'onde du domaine du visible TL et/ou de l'infrarouge TIR différenciée(s) par rapport à celle que présente le reste de la plaque, de préférence inférieure d'au moins 10 %.According to an additional characteristic, the flat bottom can have a transmission in the wavelengths of the visible T T and / or infrared T IR domain differentiated from that of the rest of the plate, from preferably at least 10% lower.

Une telle caractéristique est avantageuse d'un point de vue esthétique dans la mesure où l'on peut conférer un aspect à la concavité en contraste avec celui du reste de la plaque, communément brun transparent.Such a characteristic is advantageous from an aesthetic point of view insofar as one can give an aspect to the concavity in contrast with that of the rest of the plate, commonly transparent brown.

Selon une autre caractéristique de l'invention, le bord périphérique supérieur est surélevé par rapport au plan de la plaque.According to another characteristic of the invention, the peripheral edge upper is raised relative to the plane of the plate.

Selon une caractéristique supplémentaire de l'invention, la profondeur p de la concavité est comprise entre 20 mm et 80 mm. Avec une telle caractéristique, l'appareil de cuisson conserve un encombrement correct et la concavité présente un volume utile de cuisson suffisant vis-à-vis de la quantité d'aliment(s) à cuire et/ou à réchauffer.According to an additional characteristic of the invention, the depth p concavity is between 20 mm and 80 mm. With such characteristic, the cooking appliance retains the correct dimensions and the concavity has a sufficient useful cooking volume with respect to the quantity of food (s) to be cooked and / or reheated.

Selon une variante préférée, la concavité conforme à ce qui précède est recouverte d'une cloche. De préférence, celle-ci autorise la vision. Elle peut comporter une paroi en verre ou en vitrocéramique. Ainsi recouverte, la concavité permet à l'utilisateur d'obtenir une cuisson dite «à la vapeur » des aliments contenus dans le récipient placé à l'intérieur de la concavité ou contenus directement dans la concavité.According to a preferred variant, the concavity in accordance with the above is covered with a bell. Preferably, this allows vision. She can have a glass or glass-ceramic wall. Thus covered, the concavity allows the user to obtain so-called “steaming” of the food contained in the container placed inside the concavity or contained directly in the concavity.

Avantageusement, la cloche comporte une tôle en matériau ferromagnétique et au moins un inducteur est placé sous la concavité, de préférence dans sa partie périphérique.Advantageously, the bell comprises a sheet of material ferromagnetic and at least one inductor is placed under the concavity, of preferably in its peripheral part.

Une fois l'élément chauffant et l'inducteur mis en état de marche, le mode de cuisson des aliments s'apparente à celui d'un « four ». En effet, les aliments sont cuits directement et/ou réchauffés par le fond de la concavité mais ils le sont également par le dessus par l'intermédiaire de la cloche devenue chauffante grâce à l'inducteur.Once the heating element and the inductor are in working order, the cooking mode of food is similar to that of an "oven". Indeed, the food is cooked directly and / or heated by the bottom of the concavity but they are also from above via the bell become heated thanks to the inductor.

En outre, un tel mode de cuisson est parfaitement adapté aux nouvelles habitudes culinaires en matière de cuisson. En effet, il permet une cuisson rapide et efficace d'éléments préparés du type de ceux qui sont congelés.In addition, such a cooking method is perfectly suited to new cooking habits. Indeed, it allows cooking fast and efficient of prepared items like those that are frozen.

Lorsque la concavité ne sert pas de zone chauffante, elle peut être avantageusement recouverte d'une planche, du type planche en bois. Celle-ci est de préférence de forme complémentaire sur au moins une partie de la profondeur de la concavité.When the concavity is not used as a heating zone, it can be advantageously covered with a board, of the wooden board type. This is preferably of complementary shape on at least part of the depth of concavity.

L'utilisateur de l'appareil de cuisson dispose alors d'un plan de travail sur lequel les aliments peuvent directement être préparés.The user of the cooking appliance then has a work plan on which food can be directly prepared.

Un tel plan de travail « intégré » permet un gain de place dans la cuisine puisque l'utilisateur n'a pas besoin de ménager à l'intérieur de celle-ci un endroit spécifiquement destiné à la préparation des aliments.Such an "integrated" work plan saves space in the kitchen since the user does not need to spare inside it place specifically intended for the preparation of food.

L'appareil de cuisson qui vient d'être décrit est parfaitement adapté pour constituer une table de cuisson ou une partie d'une cuisinière.The cooking appliance which has just been described is perfectly suited for constitute a hob or part of a stove.

D'autres détails et caractéristiques avantageuses de l'invention ressortiront ci-après de la description d'un exemple de réalisation illustratif mais non limitatif, faite en référence aux figures qui représentent :

  • figure 1 : une table de cuisson conforme à l'invention intégrée au mobilier de cuisine ;
  • figure 2a : une vue en coupe selon l'axe A-A d'une partie de la table de cuisson selon la figure 1 ;
  • figure 2b et 2c : une vue en coupe selon l'axe A-A de cette même partie respectivement recouverte d'une cloche et d'une planche en bois.
Other details and advantageous characteristics of the invention will emerge below from the description of an illustrative but non-limiting embodiment, made with reference to the figures which represent:
  • Figure 1 : a hob according to the invention integrated into kitchen furniture;
  • Figure 2a : a sectional view along the axis AA of a part of the hob according to Figure 1;
  • Figure 2b and 2c : a sectional view along the axis AA of the same part respectively covered with a bell and a wooden board.

Sur la figure 1 est représentée une table de cuisson 1 intégrée à un mobilier de cuisine 2. Cette table de cuisson 1 comprend une plaque de cuisson en matériau vitrocéramique 3, essentiellement plane et lisse, reposant sur un bâti métallique 4 sur lequel sont fixés quatre foyers de cuisson 5, éléments représentés en partie sur la figure 2.In Figure 1 is shown a hob 1 integrated into a kitchen furniture 2. This hob 1 includes a hob firing in vitroceramic material 3, essentially flat and smooth, resting on a metal frame 4 on which four cooking zones 5 are fixed, elements partially represented in FIG. 2.

La plaque de cuisson vitrocéramique 3 est constituée de deux modules juxtaposés 6, 7 assemblés entre eux par un joint en silicone 8, résistant à haute température et étanche.The ceramic glass hob 3 consists of two modules juxtaposed 6, 7 assembled together by a silicone seal 8, resistant to high temperature and waterproof.

Le premier module 6 comporte une concavité 9 intégrée, à côté de laquelle se trouve une zone plane et circulaire 10 de chauffe délimitée, de manière connue en soi, par une ligne d'émail blanche 11. Il comporte également dans sa partie marginale des touches sensitives 12, c'est-à-dire actionnées par l'approche d'un doigt. Les touches sensitives 12 constituent les moyens de commande respectifs des quatre foyers de cuisson 5 fixés sous la plaque 3. Le deuxième module 7, quant à lui, comporte également une zone circulaire et plane 13 de chauffe ainsi qu'une ouverture 14 dans laquelle est inséré un brûleur à gaz 15 constituant l'un des quatre foyers de cuisson 5. Autour de l'ouverture 14 sont répartis trois bossages 141, 142, 143 destinés à supporter un récipient de cuisson dont le contenu est à chauffer par le brûleur 15. Ces bossages sont obtenus conformément à la technique décrite dans la demande de brevet WO 97/00407.The first module 6 has an integrated concavity 9, next to which is a flat and circular heating zone 10 delimited, of in a manner known per se, by a line of white enamel 11. It comprises also in its marginal part of the sensitive keys 12, that is to say operated by the approach of a finger. The sensor keys 12 constitute the respective control means of the four cooking zones 5 fixed under the plate 3. The second module 7, meanwhile, also has a zone circular and flat 13 for heating and an opening 14 in which is inserted a gas burner 15 constituting one of the four cooking zones 5. Around the opening 14 are distributed three bosses 141, 142, 143 intended to support a cooking container whose contents are to be heated by the burner 15. These bosses are obtained in accordance with the technique described in patent application WO 97/00407.

Les autres foyers de cuisson 5 sont constitués d'une part de deux éléments chauffants, non représentés, comportant chacun une lampe halogène placés respectivement sous les deux zones planes et circulaires de chauffe 10, 13 et d'un élément chauffant 5, représenté à la figure 2, constitué par une résistance électrique 16 sous la forme d'un ensemble de fils métalliques conducteurs 17.The other cooking zones 5 consist of two parts heating elements, not shown, each comprising a halogen lamp placed respectively under the two flat and circular heating zones 10, 13 and a heating element 5, represented in FIG. 2, constituted by a electrical resistance 16 in the form of a set of metal wires conductors 17.

La figure 2 est une vue en coupe selon l'axe A-A de la concavité 9 intégrée au premier module 6 précité. Cette concavité 9 comporte un fond plat 18, parallèle au plan de la plaque 3 et de diamètre circulaire et de l'ordre de 300 mm. La profondeur p de la concavité 9 est environ égale à 50 mm. Son bord périphérique supérieur est surélevé par rapport au plan de la plaque 3.Figure 2 is a sectional view along the axis A-A of the concavity 9 integrated into the aforementioned first module 6. This concavity 9 has a flat bottom 18, parallel to the plane of the plate 3 and of circular diameter and of the order of 300 mm. The depth p of the concavity 9 is approximately equal to 50 mm. His upper peripheral edge is raised relative to the plane of the plate 3.

Immédiatement sous le fond plat 18 de la concavité 9 est placée une résistance électrique 16 sous la forme d'un ensemble de fils métalliques conducteurs cylindriques 17 agencés de telle sorte qu'une fois alimenté en courant il chauffe de manière homogène toute la surface circulaire dudit fond 18.Immediately under the flat bottom 18 of the concavity 9 is placed a electrical resistance 16 in the form of a set of metal wires cylindrical conductors 17 arranged so that once supplied with current it heats homogeneously the entire circular surface of said bottom 18.

Cet ensemble de fils métalliques 17 est fixé à un support en matériau céramique 19, lui-même étant monté dans le bâti métallique 4 de la table de cuisson 1.This set of metal wires 17 is fixed to a support made of material ceramic 19, itself being mounted in the metal frame 4 of the table cooking 1.

A la périphérie inférieure de la concavité est monté de manière serrée avec le support céramique 19 un inducteur 20.Tightly mounted on the lower periphery of the concavity with the ceramic support 19 an inductor 20.

Sur la figure 2b on voit que la concavité est recouverte d'une cloche 21 qui comporte une paroi extérieure 22 en vitrocéramique et à l'intérieur une tôle en matériau ferromagnétique 23 autorisant la vision par l'intermédiaire de son ouverture 24. La tôle en matériau ferromagnétique 23 constitue l'autre partie du moyen de chauffage par induction complétée par l'inducteur 20.In Figure 2b we see that the concavity is covered with a bell 21 which has an outer wall 22 of ceramic glass and inside a sheet made of ferromagnetic material 23 allowing vision through its opening 24. The sheet of ferromagnetic material 23 constitutes the other part induction heating means supplemented by inductor 20.

Lors de sa conception, l'homme de l'art veillera à ce que sa structure soit telle qu'une fois l'inducteur 20 en état de marche, les courants qui la traversent, dits « d'échauffement », soient suffisants pour assurer une puissance de chauffe minimale à l'intérieur de l'enceinte délimitée justement par la cloche 21 et la concavité 9.When designing, the skilled person will ensure that its structure either such that once the inductor 20 in working order, the currents which cross, called "warm-up", are sufficient to ensure a minimum heating power inside the precisely delimited enclosure by bell 21 and concavity 9.

En particulier, il veillera pour des facilités de fabrication industrielle et de montage à l'intérieur de la cloche 21 à réaliser cette tôle 23 en une seule pièce.In particular, he will watch over industrial manufacturing facilities and mounting inside the bell 21 to make this sheet 23 in a single room.

Le mode de cuisson de cet ensemble est « libre » et dépend de la mise en état de marche simultané ou non de la résistance électrique 16 et de l'inducteur 20.The cooking mode of this set is "free" and depends on the setting whether or not the electrical resistance 16 and inductor 20.

La figure 2c, enfin, montre que lorsque aucun de ces éléments 16, 20 est en état de marche, la concavité peut être recouverte d'une planche en bois 25 de forme complémentaire sur une hauteur h de 30 mm. Figure 2c, finally, shows that when none of these elements 16, 20 is in working order, the concavity can be covered with a wooden board 25 of complementary shape over a height h of 30 mm.

Pour valider la fonction de cuisson directe obtenue selon l'invention, on a réalisé différents essais de cuisson de plusieurs types d'aliments placés directement dans la concavité 9, à l'aide exclusivement de la résistance électrique 1 6.To validate the direct cooking function obtained according to the invention, we carried out different cooking tests of several types of food placed directly in concavity 9, using exclusively the resistance electric 1 6.

Le tableau 1 ci-dessous indique, pour chaque type d'aliments, la gamme des températures établies pour réaliser la cuisson en °C ainsi que le temps nécessaire en min.Table 1 below indicates, for each type of food, the range temperatures set for cooking in ° C as well as the time required in min.

Lorsque de l'huile a été utilisée pour cuire l'aliment considéré, cela est précisé entre parenthèses. Exemples Types d'aliments Gamme de température de cuisson (°C) Temps nécessaire à la cuisson (min) 1 Escalope de porc (Huile) 350-400 6 min pour 150 g de viande 2 Escalope de porc 350-400 6 min pour 150 g de viande 3 Gigot d'agneau (Huile) 350-400 8 min pour 200 g de viande 4 Steak haché (Huile) 350-400 6 min pour 150 g de viande 5 Steak haché 350-400 6 min pour 150 g de viande 6 Chipolatas (Huile) 210-250 20 min pour 6 saucisses 7 Chipolatas 210-250 20 min pour 6 saucisses 8 Tomate (Huile) 250-280 12 à 18 min pour 8 rondelles 9 Tomate 250-280 12 à 18 min pour 8 rondelles 10 Oignons (Huile) 250-280 18 min pour 4 rondelles 11 Oignons 250-280 18 min pour 4 rondelles 12 Crêpes 200 3 à 4 min par crêpe When oil has been used to cook the food, this is indicated in brackets. Examples Food types Cooking temperature range (° C) Cooking time (min) 1 Pork cutlet (Oil) 350-400 6 min for 150 g of meat 2 Pork cutlet 350-400 6 min for 150 g of meat 3 Leg of lamb (Oil) 350-400 8 min for 200 g of meat 4 Ground beef (Oil) 350-400 6 min for 150 g of meat 5 Chopped steak 350-400 6 min for 150 g of meat 6 Chipolatas (Oil) 210-250 20 min for 6 sausages 7 Chipolatas 210-250 20 min for 6 sausages 8 Tomato (Oil) 250-280 12 to 18 min for 8 washers 9 Tomato 250-280 12 to 18 min for 8 washers 10 Onions (Oil) 250-280 18 min for 4 washers 11 Onions 250-280 18 min for 4 washers 12 Pancakes 200 3 to 4 min per pancake

On a ensuite procédé au nettoyage de la concavité après trois cuissons d'un même type d'aliment, exception faite des chipolatas où le nettoyage a été réalisé après chaque cuisson de 6 saucisses.We then proceeded to clean the concavity after three firings of the same type of food, except chipolatas where cleaning has been made after each cooking of 6 sausages.

Les produits utilisés sont, tout d'abord, un produit couramment utilisé pour nettoyer la vaisselle et le produit commercialisé sous la dénomination commerciale « Kiraviv » utilisé usuellement pour le nettoyage des plaques vitrocéramiques.The products used are, first of all, a commonly used product for cleaning dishes and the product sold under the name commercial "Kiraviv" commonly used for cleaning plates vitroceramics.

On a, parallèlement au nettoyage, relevé l'indice de gravité de chaque type d'aliment. Cet indice est représentatif de la difficulté mise pour nettoyer l'aliment considéré et donc son aptitude à tâcher.In addition to cleaning, we noted the severity index of each type of food. This index is representative of the difficulty put to clean the food considered and therefore its ability to try.

On précise ici que, plus l'opération de nettoyage a été difficile, plus l'indice de gravité est élevé.It is stated here that the more difficult the cleaning operation, the more the severity index is high.

On précise également que les indices de gravité ont été relevés après la cuisson de 20 kg de chaque type d'aliment.It is also specified that the severity indices were noted after the cooking 20 kg of each type of food.

Le tableau 2 ci-dessous regroupe, pour les mêmes types d'aliments que ceux du tableau 1, les nettoyages subis ainsi que l'indice de gravité. Exemples Produit(s) utilisé(s) pour le nettoyage Indice de gravité 1 Kiraviv puis vaisselle 0,03 2 Kiraviv puis vaisselle 0,03 3 Kiraviv puis vaisselle 0,03 4 Kiraviv puis vaisselle 0,03 5 Kiraviv puis vaisselle 0,03 6 Kiraviv puis vaisselle 0 7 Kiraviv puis vaisselle 0 8 Vaisselle 0 9 Vaisselle 0 10 Vaisselle 0 11 Vaisselle 0 12 Vaisselle 0 Table 2 below groups together, for the same types of food as those in Table 1, the cleanings undergone as well as the severity index. Examples Product (s) used for cleaning Severity rating 1 Kiraviv then dishes 0.03 2 Kiraviv then dishes 0.03 3 Kiraviv then dishes 0.03 4 Kiraviv then dishes 0.03 5 Kiraviv then dishes 0.03 6 Kiraviv then dishes 0 7 Kiraviv then dishes 0 8 Washing up 0 9 Washing up 0 10 Washing up 0 11 Washing up 0 12 Washing up 0

A la lecture de ces tableaux, il ressort clairement que la cuisson directe d'aliments sur une plaque de cuisson vitrocéramique proposée par l'invention ainsi que le nettoyage s'y rapportant ne posent pas de problème.Reading these tables, it becomes clear that direct cooking food on a ceramic hob proposed by the invention as well as the related cleaning is not a problem.

Bien évidemment, il va de soi que diverses modifications peuvent être apportées sans pour autant sortir du cadre de l'invention.Obviously, it goes without saying that various modifications can be made without departing from the scope of the invention.

Ainsi, l'inducteur 20 peut être remplacé par un élément chauffant et permettre ainsi une cuisson plutôt de type « vapeur ».Thus, the inductor 20 can be replaced by a heating element and thus allowing cooking rather of the “steam” type.
