Description
La présente invention a pour objet un appareil de cuisson à induction, et concerne plus précisément la plaque de cuisson équipant un tel appareil.The present invention relates to a cooking appliance with induction, and more specifically relates to the hob fitted to such a apparatus.
A l'heure actuelle, toutes les tables de cuisson à foyers radiants, halogènes et à induction, sont équipées d'une plaque en vitrocéramique, placée au-dessus des foyers, et destinée à supporter les récipients à chauffer. Le principal avantage de la vitrocéramique est qu'elle possède des caractéristiques thermiques très intéressantes, et notamment un coefficient de dilatation quasiment nul, ce qui rend son utilisation indispensable dans le cas des foyers halogènes et radiants, pour lesquels la plaque peut atteindre des températures de l'ordre de 700°C. De tels appareils de cuisson sont par exemple connus d'après les documents DE-U-8 914 894 et DE-A-3 440 868. Du fait que les appareils qui y sont décrits ont des éléments chauffants radiants, leurs surfaces de cuisson ne peuvent être en verre (borosilicate ou sodocalcique), qui est nettement moins cher que la vitrocéramique. En outre, du fait que les plaques chauffantes connues d'après ledit document DE-U-8 914 894 sont portées à une température relativement élevée, leur bord doit être relativement éloigné (environ 40 mm au moins) du support environnant, si ce dernier est réalisé en matière plastique. De plus, dans ce dernier cas, si l'on pose un récipient de cuisson de grandes dimensions sur la plaque chauffante, il communique par conduction de la chaleur au support entourant la plaque, ce qui oblige soit à augmenter les dimensions de la plaque chauffante (donc à en augmenter le prix de revient), soit à renoncer à l'utilisation de matière plastique pour le support.At present, all hobs with radiant fireplaces, halogen and induction, are equipped with a ceramic hob, placed above the fireplaces, and intended to support the containers heat. The main advantage of glass ceramic is that it has very interesting thermal characteristics, including a coefficient almost no expansion, which makes its use essential in the halogen and radiant hearths, for which the plate can reach temperatures of the order of 700 ° C. Such cooking appliances are by example known from documents DE-U-8 914 894 and DE-A-3 440 868. Because the devices described there have heating elements radiant, their cooking surfaces cannot be made of glass (borosilicate or soda-lime), which is significantly cheaper than glass ceramic. In in addition, the fact that the hot plates known from said document DE-U-8 914 894 are brought to a relatively high temperature, their edge must be relatively distant (at least 40 mm) from the support surrounding, if the latter is made of plastic. In addition, in this last case, if a large cooking container is placed on the hot plate, it communicates by conduction of heat to the support surrounding the plate, which requires either to increase the dimensions of the hot plate (therefore to increase the cost price), or to renounce when using plastic for the support.
Par contre, l'avantage précédent n'est pas exploité dans le chauffage par foyer à induction. En effet, le chauffage se produisant directement au niveau du récipient placé au-dessus de l'inducteur, l'élévation en température du plan de cuisson, due à la conduction thermique du récipient vers le plan, ne dépasse pas, dans le pire des cas, 300 à 350°C selon la régulation de température utilisée.On the other hand, the preceding advantage is not exploited in the heating by induction fireplace. Indeed, the heating occurring directly at the level of the container placed above the inductor, the rise in temperature of the hob, due to conduction thermal from the container to the plane, does not exceed, in the worst case, 300 to 350 ° C depending on the temperature regulation used.
Or, la vitrocéramique est un matériau qui coûte cher, ce qui grève quasiment inutilement, compte tenu de la remarque précédente, le prix des appareils ménagers. However, glass ceramic is an expensive material, which strikes almost unnecessarily, given the previous remark, the price of household appliances.
Le but principal de la présente invention est de trouver une solution de remplacement permettant de réduire notablement les coûts d'un appareil de cuisson à induction.The main purpose of the present invention is to find a replacement solution that significantly reduces the costs of a induction cooking appliance.
Pour ce faire, la présente invention a pour objet un appareil de cuisson à induction comportant une plaque de cuisson sensiblement plane et au moins un foyer inducteur placé sous ladite plaque, ladite plaque étant constituée par l'assemblage d'une première partie comportant un trou de taille voisine du diamètre du foyer inducteur et supérieure au diamètre du foyer inducteur , et d'une deuxième partie en verre, destinée à supporter un récipient à chauffer, ladite deuxième partie obturant totalement le trou de la première partie, caractérisé en ce que la première partie est obtenue par moulage d'un matériau thermorésistant, et en ce que la deuxième partie possède une surface supérieure surélevée par rapport à la surface supérieure de la première partie.To do this, the subject of the present invention is an induction cooking appliance comprising a plate of substantially flat cooking and at least one inducing hearth placed under said plate, said plate being constituted by the assembly of a first part with a hole of size close to the diameter of the hearth inductor and greater than the diameter of the inductor hearth, and second glass part, intended to support a container for heating, said second part completely closing the hole of the first part, characterized in that the first part is obtained by molding of a heat-resistant material, and in that the second part has an upper surface raised relative to the upper surface of the first part.
Les caractéristiques et différents avantages procurés par l'invention seront mieux compris au vu de la description suivante, faite en référence aux figures annexées :
- La figure 1 illustre une vue partielle en élévation du plan de cuisson équipant un appareil de chauffage à induction selon l'invention ;
- Les figures 2a à 2f illustrent différentes variantes de configurations géométriques pour un plan de cuisson équipant un appareil selon l'invention, en vue de dessus.
- FIG. 1 illustrates a partial elevation view of the hob equipping an induction heating device according to the invention;
- FIGS. 2a to 2f illustrate different variants of geometric configurations for a hob fitted to an appliance according to the invention, seen from above.
Sur la figure 1, on a représenté schématiquement, en vue
partielle en élévation, un récipient 1 à chauffer placé sur la plaque 2 d'un
appareil de cuisson à induction comportant un foyer inducteur 3.In Figure 1, there is shown schematically, in view
partial elevation, a container 1 to be heated placed on the
Le foyer inducteur 3 est composé classiquement par une ou
plusieurs bobines placés concentriquement. Les bobines sont de forme
généralement circulaires et le diamètre du foyer inducteur doit de préférence
correspondre au diamètre du plus grand récipient à chauffer, ce dernier
étant posé sur la plaque de cuisson 2, en regard du foyer inducteur.The inducing
Conformément à l'invention, la plaque de cuisson comporte deux parties de matériaux différents :According to the invention, the hob has two parts of different materials:
Une première partie 21 comporte un trou 22 dont la taille est
supérieure au diamètre du foyer inducteur, de manière à laisser ce foyer
totalement apparaítre lorsque la première partie est mise en place.A
Selon l'invention, cette première partie est moulée, par injection ou par compression, en un matériau thermorésistant. According to the invention, this first part is molded, by injection or by compression, in a heat-resistant material.
Dans une première variante de réalisation possible, le matériau utilisé pour le moulage est un thermoplastique, de préférence chargé par des particules minérales (fibres de verre, silice), afin d'éviter les imperfections de moulage.In a first possible variant, the material used for molding is a thermoplastic, preferably loaded by mineral particles (glass fibers, silica), in order to avoid molding imperfections.
Dans une variante préférée de l'invention, on utilise un matériau thermodurcissable, qui présente une très grande stabilité mécanique et thermique par rapport à un matériau thermoplastique.In a preferred variant of the invention, a material is used thermosetting, which has very high mechanical stability and thermal compared to a thermoplastic material.
Par ailleurs, la plaque de cuisson selon l'invention comporte
également une deuxième partie 20 en verre, destinée à porter le récipient à
chauffer. Cette deuxième partie est dimensionnée en surface de manière à
recouvrir totalement le trou 22 de la première partie 21.Furthermore, the hob according to the invention comprises
also a
L'épaisseur de la deuxième partie est déterminée de manière à optimiser l'échauffement du récipient 1 par induction, le foyer inducteur étant sur toute sa surface en contact avec la partie inférieure de cette deuxième partie.The thickness of the second part is determined so as to optimize the heating of the container 1 by induction, the inducing focus being over its entire surface in contact with the lower part of this second part.
Le verre utilisé peut être une vitrocéramique classique. Dans ce cas, on a réduit la quantité de matériau nécessaire par rapport aux tables en vitrocéramique connues, et donc, le coût total de l'appareil.The glass used can be a conventional glass ceramic. In this case, we reduced the amount of material needed compared to the tables in glass ceramic known, and therefore, the total cost of the device.
On peut également utiliser un verre borosilicaté, lequel présente une bonne stabilité en température, et est moins coûteux.You can also use a borosilicate glass, which has good temperature stability, and is less expensive.
Dans une troisième variante préférée, on utilise un verre
sodocalcique, type de verre généralement employé pour réaliser les vitres.
Par ailleurs, le verre sodocalcique peut être avantageusement trempé afin
d'améliorer sa résistance aux chocs mécaniques. Pour conserver une bonne
tenue mécanique du verre lié à sa trempe, on peut prévoir avantageusement
d'utiliser un dispositif de régulation de température évitant, par réglage de la
puissance du foyer inducteur, que la partie 20 n'atteigne des températures
supérieures à un certain seuil, typiquement de 320°C.In a third preferred variant, a glass is used
soda-lime, type of glass generally used to make windows.
Furthermore, soda-lime glass can advantageously be tempered so as to
to improve its resistance to mechanical shock. To keep good
mechanical strength of the glass linked to its tempering, advantageously can be provided
to use a temperature control device avoiding, by adjusting the
power of the inducing hearth, that
Les verres sodocalciques et borosilicatés sont préférables à la vitrocéramique car ils conservent leurs caractéristiques diélectriques en température.Soda-lime and borosilicate glasses are preferable to glass-ceramic because they retain their dielectric characteristics in temperature.
L'assemblage des deux parties 20, 21 doit permettre une bonne
étanchéité et tenir compte des coefficients de dilatation différents des deux
matériaux utilisés : The assembly of the two
Dans l'exemple représenté sur la figure 1, la première partie 21
comporte un épaulement périphérique 23 sur le pourtour du trou 22, sur
lequel vient reposer la deuxième partie 20. Les deux parties sont par
exemple assemblées par collage siliconé, pour assurer une étanchéité
maximale.In the example shown in Figure 1, the
Dans une autre variante possible, l'assemblage peut être effectué par l'intermédiaire d'un joint d'étanchéité.In another possible variant, assembly can be carried out through a seal.
Compte tenu de la différence dans les coefficients de dilatation thermique des matériaux utilisés (le coefficient de dilatation du matériau thermodurcissable pouvant être deux fois plus grand que celui du verre), la surface supérieure de la deuxième partie est surélevée par rapport à la surface supérieure de la première partie, par exemple de l'ordre de 1 millimètre.Taking into account the difference in the expansion coefficients thermal of the materials used (the coefficient of expansion of the material thermosetting can be twice as large as that of glass), the upper surface of the second part is raised relative to the upper surface of the first part, for example of the order of 1 millimeter.
Ainsi, même en cas d'importante dilatation, le fond du récipient n'est jamais en contact avec le matériau thermorésistant de la première partie.Thus, even in the event of significant expansion, the bottom of the container is never in contact with the heat-resistant material of the first part.
Les avantages procurés par l'invention sont nombreux:The advantages provided by the invention are numerous:
Tout d'abord, le coût global d'un appareil de cuisson équipé alune
plaque conforme à l'invention est significativement réduit par rapport au
même appareil équipé d'une plaque vitrocéramique (le foyer inducteur peut
être recouvert d'une plaque 20 en verre, bien moins chère que la
vitrocéramique, et le support 21 peut être en matière thermoplastique ou
thermodurcissable). De plus, la température de la plaque étant plus faible
que dans le cas d'éléments radiants, ses dimensions peuvent être réduites.
La distance entre les bords du foyer inducteur 3 et le support 21 peut être
très faible (environ 4 mm).First, the overall cost of a cooking appliance fitted with alune
plate according to the invention is significantly reduced compared to
same appliance fitted with a ceramic hob (the induction cooker can
be covered with a
Du fait que la plaque 20 dépasse d'environ 1 mm le niveau du
support 21, il n'y a pas entre eux d'échange thermique par conduction (par O
l'intermédiaire des récipients à chauffer), ce qui permet de réaliser le
support 21 en matériau thermodurcissable ou thermoplastique.Because the
Par ailleurs, la première partie étant moulée, des fonctions supplémentaires telles que le clavier de commande ou la sortie d'air de refroidissement peuvent y être intégrées directement, avec des recherches esthétiques nouvelles, en particulier en matiére de volume. Furthermore, the first part being molded, functions additional devices such as the control keypad or the air outlet of cooling can be integrated directly, with searches new aesthetics, in particular in terms of volume.
Différentes configurations géométriques sont possibles, comme le montrent les figures 2a à 2f. (formes circulaires, elliptiques (figure 2a) ou carrées (figure 2b) pour des appareils équipés de quatre foyers inducteurs classiques, ou de deux foyers inducteurs pour plats à poissons (figures 2c à 2f)).Different geometric configurations are possible, such as show Figures 2a to 2f. (circular, elliptical shapes (Figure 2a) or square (figure 2b) for devices fitted with four induction cookers conventional, or two induction cookers for fish dishes (Figures 2c to 2 F)).
Enfin, les différents matériaux précédemment décrits permettent d'élargir la palette des couleurs, actuellement limitée, dans le cas de la vitrocéramique, à deux couleurs (brun et blanc).Finally, the different materials previously described allow to widen the palette of colors, currently limited, in the case of vitroceramic, two colors (brown and white).
