Description

La présente invention concerne de manière générale un système de centrage d'un appareil électroménager ou d'un récipient de cuisson sur une table à induction.The present invention generally relates to a centering system of a household appliance or cooking vessel on an induction table.

Plus particulièrement le système de centrage concerne les appareils électroménagers ou les récipients de cuisson qui sont alimentés ou chauffés sans fil en énergie par une table à induction pour réaliser de la chauffe ou une récupération d'énergie pour alimenter des fonctions annexes à la chauffe ou encore une combinaison des deux.More particularly, the centering system relates to household appliances or cooking vessels that are powered or heated wirelessly energy by an induction table to achieve heating or energy recovery to supply functions related to heating or even a combination of both.

Il est connu dans l'art antérieur des systèmes de marquages circulaires sur les plaques de cuisson des générateurs ou des tables à induction comme en particulier ceux divulgués dans les documents JP2000323270 ou WO2009147664 . Dans ces documents le marquage a pour but de repérer le ou les inducteurs et ainsi de bien positionner l'appareil électroménager ou le récipient de cuisson à l'intérieur du marquage afin d'assurer un maximum de transfert d'énergie entre les différents éléments.Circular markings on the cooking plates of generators or induction tables, such as those disclosed in the documents, are known in the prior art. JP2000323270 or WO2009147664 . In these documents the marking is intended to identify the inductor (s) and thus to properly position the appliance or the cooking vessel inside the marking to ensure maximum energy transfer between the various elements.

Toutefois, et dans le cas de la récupération d'énergie pour alimenter des fonctions annexes à la chauffe, pour que ces dispositifs fonctionnent correctement il est nécessaire que l'inducteur de l'appareil à alimenter soit idéalement positionné. Pour cela il doit se positionner en face de l'inducteur du générateur à induction. Le parfait alignement de ces inducteurs permet de tirer le maximum de puissance avec le meilleur rendement du transfert d'énergie sans contact. C'est une condition impérative pour assurer un transfert d'énergie suffisant tout en ayant un dimensionnement du générateur à induction et de l'appareil électroménager ou du récipient de cuisson le plus optimum possible.However, and in the case of energy recovery to supply functions related to heating, for these devices to work properly it is necessary that the inductor of the device to be powered is ideally positioned. For this it must be positioned in front of the inductor of the induction generator. The perfect alignment of these inductors allows to get the most power with the best efficiency of contactless energy transfer. It is an imperative condition to ensure a sufficient energy transfer while having a dimensioning of the induction generator and the household appliance or cooking vessel as optimum as possible.

Tolérer un décalage entre le générateur à induction et l'appareil électroménager ou le récipient de cuisson reviendrait à diminuer le rendement global de l'application et donc à sur dimensionner le générateur à induction ce qui impacterait le coût final.
En outre ces systèmes présentent également l'inconvénient que le centrage de l'appareil électroménager ou du récipient de cuisson s'effectue à l'appréciation de l'utilisateur et en général de manière peu précise sans que l'utilisateur soit informé du bon alignement de l'appareil électroménager ou du récipient de cuisson sur la table à induction.Tolerance of an offset between the induction generator and the appliance or cooking vessel would reduce the efficiency global application and therefore to sizing the induction generator which would impact the final cost.
In addition, these systems also have the disadvantage that the centering of the appliance or cooking vessel is made at the discretion of the user and generally not very accurate without the user being informed of the proper alignment appliance or cookware on the induction hob.

DE 20 2007 013494 U1 décrit un système électroménager comprenant un appareil électroménager ou un récipient de cuisson, une table à induction , et un système de centrage prévu pour fonctionner avec l'appareil électroménager ou le récipient de cuisson et la table à induction, la table à induction comprenant un inducteur générateur qui est prévu pour fournir de l'énergie et qui est positionné dans la table à induction, l'appareil électroménager ou le récipient de cuisson étant alimentés et/ou chauffés sans fil par l'énergie fournie par l'inducteur générateur, le système de centrage comprenant un dispositif optique positionné dans la table à induction; le dispositif optique étant prévu pour générer ou recevoir un ou plusieurs rayons optiques. DE 20 2007 013494 U1 discloses an appliance system comprising an appliance or a cooking vessel, an induction hob, and a centering system adapted to operate with the appliance or cooking vessel and the induction hob, the hob comprising an inductor a generator which is provided to supply energy and which is positioned in the induction hob, the appliance or cooking vessel being powered and / or heated wirelessly by the energy supplied by the generator inductor, the system centering device comprising an optical device positioned in the induction table; the optical device being provided for generating or receiving one or more optical rays.

Un but de la présente invention est de répondre aux inconvénients de l'art antérieur mentionnés ci-dessus et en particulier tout d'abord de proposer un système qui puisse informer l'utilisateur du bon alignement d'un appareil électroménager ou un récipient de cuisson avec la table à induction dans le but de transférer un maximum d'énergie en vue de la chauffe de l'appareil électroménager ou du récipient de cuisson ou de la récupération d'énergie.An object of the present invention is to meet the disadvantages of the prior art mentioned above and in particular first of all to propose a system that can inform the user of the proper alignment of a household appliance or a cooking vessel. with the induction hob for the purpose of transferring as much energy as possible for heating the appliance or cooking vessel or for energy recovery.

Pour cela l'invention concerne un système électroménager comprenant un appareil électroménager ou un récipient de cuisson, une table de cuisson, et un système de centrage prévu pour fonctionner avec l'appareil électroménager (ou le récipient de cuisson et la table à induction, la table à induction comprenant un inducteur générateur qui est prévu pour fournir de l'énergie et qui est positionné dans la table à induction, l'appareil électroménager ou le récipient de cuisson étant alimentés et/ou chauffés sans fil par l'énergie fournie par l'inducteur générateur, le système de centrage comprenant un premier dispositif optique positionné dans l'appareil électroménager ou le récipient de cuisson et un second dispositif optique positionné dans la table à induction; le premier dispositif optique étant prévu pour générer ou recevoir un ou plusieurs rayons optiques et le second dispositif optique étant prévu pour générer ou recevoir un ou plusieurs rayons optiques; le système de centrage étant prévu pour détecter l'alignement du premier dispositif optique par rapport au second dispositif optique à partir de un ou plusieurs rayons optiques émis par le premier dispositif optique et reçus par le second dispositif optique ou de un ou plusieurs rayons optiques émis par le second dispositif optique et reçus par le premier dispositif optique.For this purpose, the invention relates to an appliance system comprising an appliance or a cooking vessel, a hob, and a centering system adapted to operate with the appliance (or the cooking vessel and the induction hob, the induction table comprising a generator inductor which is provided to supply energy and which is positioned in the induction table, the appliance or cooking vessel being supplied and / or heated wirelessly by the energy supplied by the generator inductor, the centering system comprising a first optical device positioned in the appliance or the cooking vessel and a second optical device positioned in the induction table, the first optical device being adapted to generate or receive one or more radii optical and the second optical device being provided for generating or receiving one or more rayo optics, the centering system being arranged to detect the alignment of the first optical device with respect to the second optical device from one or more optical rays emitted by the first optical device and received by the second optical device or one or more optical rays emitted by the second optical device and received by the first optical device.

Selon un mode de réalisation, l'appareil électroménager ou le récipient de cuisson comprend un inducteur récepteur destiné à récupérer de l'énergie et le premier dispositif optique est positionné au milieu de l'inducteur récepteur et le second dispositif optique est positionné au milieu de l'inducteur générateur.According to one embodiment, the appliance or cooking vessel comprises a receiver inductor for recovering energy and the first optical device is positioned in the middle of the receiver inductor and the second optical device is positioned in the middle of the receiver inductor. the generator inductor.

Le fait de placer les dispositifs optiques au milieu des inducteurs permet de n'utiliser que deux dispositifs optiques et lorsque ceux-ci sont alignés l'appareil électroménager ou le récipient de cuisson peut tourner autour de l'axe formé par les deux dispositifs optiques alignés sans que les inducteurs se décalent l'un par rapport à l'autre.Placing the optical devices in the middle of the inductors makes it possible to use only two optical devices and when these are aligned the appliance or the cooking vessel can rotate about the axis formed by the two aligned optical devices without the inductors are shifted relative to each other.

Selon un mode de réalisation, l'inducteur récepteur et l'inducteur générateur sont alignés lorsque le premier dispositif optique reçoit un ou plusieurs rayons optiques émis par le second dispositif optique ou lorsque le second dispositif optique reçoit un ou plusieurs rayons optiques émis par le premier dispositif optique. Les rayons optiques doivent être reçus de façon directe afin que les rayons parasites ne soient pas pris en compte par les différents dispositifs optiques.According to one embodiment, the receiver inductor and the generator inductor are aligned when the first optical device receives one or more optical rays emitted by the second optical device or when the second optical device receives one or more optical rays emitted by the first optical device. optical device. Optical rays must be received directly so that the spurious rays are not taken into account by the different optical devices.

et les données d'état ou de commande peuvent être échangées de manière bidirectionnelle entre l'appareil électroménager ou le récipient de cuisson et la table à induction par l'intermédiaire du premier dispositif optique et du second dispositif optique uniquement lorsque le premier dispositif optique et le second dispositif optique sont alignés. L'appareil électroménager ou le récipient de cuisson et la table à induction peuvent ainsi communiquer l'un avec l'autre par l'intermédiaire des rayons optiques et cela seulement lorsque les dispositifs optiques sont alignés ce qui permet d'évacuer la possibilité d'avoir des informations parasites qui pourraient provenir d'autres sources.According to one embodiment, the one or more optical rays emitted by the first optical device or by the second optical device comprise:
  • status data of the appliance or cookware or induction hob so as to know the state of the appliance or cookware or induction hob or

The appliance or the cooking vessel and the induction table can thus communicate with each other via the optical rays and this only when the optical devices are aligned which allows to evacuate the possibility of have spurious information that could come from other sources.

En d'autres termes la solution proposée permet par l'intermédiaire d'un seul et même moyen d'assurer une communication bidirectionnelle entre l'appareil électroménager et la table à induction ainsi qu'un indicateur de centrage de l'appareil électroménager par rapport à la table à induction.In other words, the proposed solution makes it possible, via one and the same means, to provide bidirectional communication between the appliance and the induction hob and a centering indicator of the appliance in relation to the appliance. at the induction table.

Selon un mode de réalisation, l'appareil électroménager ou le récipient de cuisson ou la table à induction comprend un afficheur permettant de visualiser l'alignement du premier dispositif optique avec le second dispositif optique. L'intérêt d'un tel afficheur est d'avoir un dispositif permettant de rendre l'information de centrage visible à un utilisateur.According to one embodiment, the appliance or cooking vessel or induction table comprises a display for viewing the alignment of the first optical device with the second optical device. The advantage of such a display is to have a device for rendering the centering information visible to a user.

Selon un mode de réalisation, l'afficheur comprend une ou plusieurs diodes électroluminescentes qui sont dans un premier état d'allumage si le premier dispositif optique est aligné avec le second dispositif optique et qui sont dans un second état d'allumage si le premier dispositif optique n'est pas aligné avec le second dispositif optique. L'utilité d'avoir une telle indication du centrage est de pouvoir connaitre rapidement le statut de l'alignement des dispositifs optiques entre eux.According to one embodiment, the display comprises one or more light-emitting diodes which are in a first ignition state if the first optical device is aligned with the second optical device and which are in a second ignition state if the first device optic is not aligned with the second optical device.

Selon un mode de réalisation, l'appareil électroménager ou le récipient de cuisson ou la table à induction comprend un dispositif d'affichage de la position du rayon incident sur la dalle photosensible par rapport à la position du premier dispositif optique ou du second dispositif optique. De cette manière, on peut visualiser les positions relatives des deux systèmes optiques l'un par rapport à l'autre en temps réel et à partir de cette visualisation on peut corriger l'alignement des deux dispositifs optiques afin de les aligner.According to one embodiment, the appliance or cooking vessel or induction table comprises a device for displaying the position of the ray incident on the photosensitive slab relative to the position of the first optical device or the second optical device . In this way, it is possible to visualize the relative positions of the two optical systems with respect to one another in real time and from this visualization the alignment of the two optical devices can be corrected in order to align them.

Selon un mode de réalisation, le premier dispositif optique est un émetteur et/ou récepteur infrarouge relié à un microcontrôleur et le second dispositif optique est un émetteur et/ou récepteur infrarouge relié à un microcontrôleur. Les émetteurs et/ou récepteurs infrarouges fonctionnent dans des longueurs d'ondes dans lesquelles il y a peu d'interférences.According to one embodiment, the first optical device is a transmitter and / or infrared receiver connected to a microcontroller and the second optical device is a transmitter and / or infrared receiver connected to a microcontroller. Infrared transmitters and / or receivers operate in wavelengths in which there is little interference.

Selon un mode de réalisation, l'appareil électroménager ou le récipient de cuisson ou la table à induction comprend une interface utilisateur adaptée à recevoir en entrée des données de commande destinées à être transmises par le premier dispositif optique ou par le second dispositif optique, de manière à commander au moins une fonction de l'appareil électroménager ou du récipient de cuisson à partir de la table à induction ou à commander au moins une fonction de la table à induction à partir de l'appareil électroménager ou du récipient de cuisson.According to one embodiment, the appliance or cooking vessel or induction table comprises a user interface adapted to receive input control data to be transmitted by the first optical device or by the second optical device, in order to control at least one function of the appliance or cooking vessel from the induction hob or to control at least one function of the hob from the appliance or cooking vessel.

On comprendra mieux les buts, aspects et avantages de la présente invention, d'après la description donnée ci-après d'un mode particulier de réalisation de l'invention présenté à titre d'exemple non limitatif, en se référant aux dessins annexés dans lesquels :

  • la figure 1 est une vue générale en coupe du système électroménager dans une première position ;
  • la figure 2 est une vue générale en coupe du système électroménager dans une seconde position ;
  • la figure 3 est une vue de dessus d'une variante du système électroménager dans la position de la figure 1 ;
  • la figure 4 est une vue détaillée de dessus de la variante du système électroménager de la figure 3 dans la position de la figure 2.
La figure 1 représente une vue en coupe d'un système électroménager qui comprend un système de centrage, une table à induction 2 et un appareil électroménager 1 ou un récipient de cuisson.
Par appareil électroménager 1 on entend tous les appareils pouvant comporter des fonctions de chauffe mais également des fonctions annexes à la chauffe. Comme fonctions annexes à la chauffe on peut notamment avoir une alimentation électrique en vue de hacher, de mélanger ou en vue d'alimenter des dispositifs d'éclairage, de communications ou de visualisations.
Par fonction de chauffe d'un appareil électroménager 1 on entend qu'une partie de l'appareil électroménager 1 peut s'élever en température soit par l'intermédiaire de résistances électriques chauffantes soit par des courants induits dans une partie métallique de l'appareil électroménager 1.The aims, aspects and advantages of the present invention will be better understood from the description given below of a particular embodiment of the invention presented by way of non-limiting example, with reference to the accompanying drawings in which :
  • the figure 1 is a general sectional view of the home appliance system in a first position;
  • the figure 2 is a general sectional view of the home appliance system in a second position;
  • the figure 3 is a top view of a variant of the home appliance system in the position of the figure 1 ;
  • the figure 4 is a detailed view from above of the household appliance variant of the figure 3 in the position of the figure 2 .
The figure 1 is a sectional view of an appliance system which includes a centering system, an induction table 2 and a household appliance 1 or a cooking vessel.
By appliance 1 is meant all appliances that may include heating functions but also functions related to heating. As auxiliary functions to the heater can include a power supply for chopping, mixing or for supplying lighting devices, communications or visualizations.
By heating function of a household appliance 1 is meant that part of the household appliance 1 may rise in temperature either by means of electric heating resistors or currents induced in a metal part of the appliance 1.

Le récipient de cuisson est un récipient adapté à être posé sur une table à induction 2 et chauffé par celle-ci au niveau du fond. Le récipient de cuisson peut également comprendre des fonctions annexes à la chauffe. On retrouve de manière non limitative les fonctions annexes mentionnées ci-dessus.The cooking vessel is a container adapted to be placed on an induction table 2 and heated by it at the bottom. The cooking vessel may also include functions related to the heating. We find in a nonlimiting way the additional functions mentioned above.

La table à induction 2 comprend un ou plusieurs inducteurs 3 générateurs prévus pour fournir de l'énergie. Les un ou plusieurs inducteurs 3 générateurs sont positionnés dans la table à induction 2.The induction table 2 comprises one or more inductors 3 generators intended to provide energy. The one or more inductors 3 generators are positioned in the induction table 2.

Le système de centrage comprend un premier dispositif optique 4. Ce premier dispositif optique 4 est composé d'un capteur optique relié à un microcontrôleur 12. Ce capteur optique est soit un émetteur infrarouge, soit un récepteur infrarouge soit un émetteur-récepteur combiné. Ainsi il peut générer ou recevoir un ou plusieurs rayons optiques dans les longueurs d'ondes infrarouges. Ce capteur optique est positionné dans l'appareil électroménager 1 ou dans le récipient de cuisson. Il est positionné perpendiculairement au fond de l'appareil électroménager 1 ou au fond du récipient de cuisson de manière à ce que les un ou plusieurs rayons optiques 10 émis soient émis perpendiculairement au fond de l'appareil électroménager 1 ou au fond du récipient de cuisson.The centering system comprises a first optical device 4. This first optical device 4 is composed of an optical sensor connected to a microcontroller 12. This optical sensor is either an infrared transmitter, an infrared receiver or a combined transceiver. Thus it can generate or receive one or more optical rays in the infrared wavelengths. This optical sensor is positioned in the appliance 1 or in the cooking vessel. It is positioned perpendicular to the bottom of the appliance 1 or the bottom of the cooking vessel so that the one or more optical rays 10 emitted are emitted perpendicularly to the bottom of the appliance 1 or the bottom of the cooking vessel .

L'appareil électroménager 1 ou le récipient de cuisson, outre qu'il peut être chauffé, comprend un inducteur 6 récepteur destiné à récupérer de l'énergie afin d'alimenter des fonctions annexes à la chauffe. Le premier dispositif optique 4 est positionné au milieu de l'inducteur 6 récepteur. On entend par « positionné au milieu » que le premier dispositif optique 4 est positionné au centre du cercle quand, par exemple, l'inducteur 6 récepteur a la forme d'un cercle. D'une manière générale, si l'inducteur 6 récepteur est d'une forme quelconque ou comprend plusieurs inducteurs 6 récepteurs, on placera le premier dispositif optique 4 sur un axe de révolution du champ magnétique total formé par les un ou plusieurs inducteurs 6 récepteurs.The appliance 1 or the cooking vessel, in addition to being heated, comprises a receiver inductor 6 for recovering energy in order to supply functions related to heating. The first optical device 4 is positioned in the middle of the inductor 6 receiver. By "positioned in the middle" is meant that the first optical device 4 is positioned in the center of the circle when, for example, the receiver inductor 6 has the shape of a circle. In general, if the receiver inductor 6 is of any shape or comprises a plurality of receiver inductors 6, the first optical device 4 will be placed on an axis of revolution of the total magnetic field formed by the one or more inductor 6 receivers. .

Le système de centrage comprend également un second dispositif optique 5. Ce second dispositif optique 5 est composé d'un capteur optique relié à un microcontrôleur 13. Ce capteur optique est soit un émetteur infrarouge, soit un récepteur infrarouge soit un émetteur-récepteur combiné. Ainsi il peut générer ou recevoir un ou plusieurs rayons optiques dans les longueurs d'ondes infrarouges. Ce second dispositif optique 5 est positionné dans la table à induction 2. Ce second dispositif optique 5 est plus particulièrement positionné au milieu de l'inducteur 3 générateur et perpendiculairement au plan de la table à induction 2 de manière à ce que les un ou plusieurs rayons optiques 11 émis soient perpendiculaires au plan de la table à induction 2.The centering system also comprises a second optical device 5. This second optical device 5 is composed of an optical sensor connected to a microcontroller 13. This optical sensor is either an infrared transmitter, an infrared receiver or a combined transceiver. Thus it can generate or receive one or more optical rays in the infrared wavelengths. This second optical device 5 is positioned in the induction table 2. This second optical device 5 is more particularly positioned in the middle of the generator inductor 3 and perpendicular to the plane of the induction table 2 so that the one or more optical rays 11 emitted are perpendicular to the plane of the induction table 2.

La définition de « milieu » est ici la même que celle énoncée plus haut.The definition of "milieu" is here the same as that stated above.

D'une manière générale l'invention ne se limite pas aux longueurs d'ondes de l'infrarouge et d'autres longueurs d'ondes sont possibles dès lors que le premier ou le second dispositif optique (4, 5) est adapté à détecter ces longueurs d'ondes.In general, the invention is not limited to wavelengths of the infrared and other wavelengths are possible when the first or the second optical device (4, 5) is adapted to detect these wavelengths.

Dans la figure 1, le premier dispositif optique 4 et le second dispositif optique 5 sont décalés ce qui implique que l'inducteur 3 générateur et l'inducteur 6 récepteur ne sont pas en vis-à-vis et que le rendement de l'énergie transmise de la table à induction 2 vers l'appareil électroménager 1 n'est pas optimal.In the figure 1 , the first optical device 4 and the second optical device 5 are shifted, which implies that the inductor 3 generator and the inductor 6 receiver are not vis-à-vis and that the efficiency of the energy transmitted from the table induction 2 to the appliance 1 is not optimal.

Afin d'en informer un utilisateur, l'appareil électroménager 1, ou le récipient de cuisson ou la table à induction 2, comprend un afficheur 7 permettant de visualiser l'alignement du premier dispositif optique 4 avec le second dispositif optique 5.In order to inform a user, the appliance 1, or the cooking vessel or the induction table 2, comprises a display 7 making it possible to display the alignment of the first optical device 4 with the second optical device 5.

L'afficheur 7 comprend une ou plusieurs diodes électroluminescentes qui sont dans un premier état d'allumage si le premier dispositif optique 4 est aligné avec le second dispositif optique 5 et qui sont dans un second état d'allumage si le premier dispositif optique 4 n'est pas aligné avec le second dispositif optique 5.The display 7 comprises one or more light-emitting diodes which are in a first state of ignition if the first optical device 4 is aligned with the second optical device 5 and which are in a second state of ignition if the first optical device 4 n is not aligned with the second optical device 5.

On peut également avoir un dispositif sonore (non représenté) pour informer un utilisateur de l'alignement des dispositifs optiques (4, 5).It is also possible to have a sound device (not shown) to inform a user of the alignment of the optical devices (4, 5).

Comme visible sur les figures 1 à 4, la table à induction 2 comprend un dispositif de visualisation 8 de la présence d'un appareil électroménager 1 ou d'un récipient de cuisson sur la table à induction 2. Ce dispositif de visualisation 8 est relié au second dispositif optique 5 et il permet de détecter si un appareil électroménager 1 ou un récipient de cuisson est présent sur la table à induction 2 et d'en informer un utilisateur. En effet si le second dispositif optique 5 ne détecte pas de rayons optiques alors le dispositif de visualisation 8 indique qu'un appareil électroménager 1 ou un récipient de cuisson n'est pas présent sur la table à induction 2.As visible on Figures 1 to 4 , the induction table 2 comprises a display device 8 for the presence of an appliance 1 or a cooking vessel on the induction table 2. This display device 8 is connected to the second optical device 5 and allows to detect whether an appliance 1 or a cooking vessel is present on the induction table 2 and to inform a user. Indeed if the second optical device 5 does not detect optical rays then the display device 8 indicates that a household appliance 1 or a cooking vessel is not present on the induction table 2.

La figure 2 représente le système électroménager dans le cas où le premier dispositif optique 4 est centré avec le second dispositif optique 5. De cette manière le premier dispositif optique 4 reçoit directement les un ou plusieurs rayons optiques 11 émis par le second dispositif optique 5 et le second dispositif optique 5 reçoit directement les un ou plusieurs rayons optiques 10 émis par le premier dispositif optique 4. De cette manière la table à induction 2 est informée qu'un appareil électroménager 1 ou un récipient de cuisson est positionné sur la table à induction 2 mais l'appareil électroménager 1 ou le récipient de cuisson est également informé qu'une table à induction 2 est positionnée sous l'appareil électroménager 1 ou le récipient de cuisson.The figure 2 represents the home appliance system in the case where the first optical device 4 is centered with the second optical device 5. In this way the first optical device 4 receives directly one or more optical rays 11 emitted by the second optical device 5 and the second device optical 5 directly receives the one or more optical rays 10 emitted by the first optical device 4. In this way the induction table 2 is informed that a household appliance 1 or a cooking vessel is positioned on the induction table 2 but the The appliance 1 or the cooking vessel is also informed that an induction table 2 is positioned under the appliance 1 or the cooking vessel.

Les un ou plusieurs rayons optiques (10, 11) émis par le premier dispositif optique 4 ou par le second dispositif optique 5 comprennent des données d'état de l'appareil électroménager 1 ou du récipient de cuisson ou de la table à induction 2 de manière à connaitre l'état de l'appareil électroménager 1 ou du récipient de cuisson ou de la table à induction 2.The one or more optical rays (10, 11) emitted by the first optical device 4 or by the second optical device 5 comprise state data of the domestic appliance 1 or the cooking vessel or the induction table 2 of in order to know the state of the appliance 1 or the cooking vessel or the induction table 2.

Ces rayons optiques (10, 11) émis comprennent aussi des données de commande de l'appareil électroménager 1 ou du récipient de cuisson ou de la table à induction 2.These optical rays (10, 11) emitted also include control data of the household appliance 1 or the cooking vessel or the induction hob 2.

Ces données de commande permettent de commander le fonctionnement de l'appareil électroménager 1 ou du récipient de cuisson ou encore de la table à induction 2.This control data makes it possible to control the operation of the household appliance 1 or the cooking vessel or the induction table 2.

Les données d'état ou de commande peuvent être échangées de manière bidirectionnelle entre l'appareil électroménager 1 ou le récipient de cuisson et la table à induction 2.The status or control data can be bidirectionally exchanged between the appliance 1 or the cooking vessel and the induction hob 2.

Les figures 3 et 4 représentent une variante du système électroménager dans laquelle l'appareil électroménager 1 ou le récipient de cuisson ou la table à induction 2 comprend un dispositif de mesure du décentrage du premier dispositif optique 4 par rapport au second dispositif optique 5 ou du second dispositif optique 5 par rapport au premier dispositif optique 4. Le dispositif de mesure du décentrage comprend une dalle 9 photosensible aux rayons optiques. Elle est positionnée sur la table à induction 2 ou sur le fond de l'appareil électroménager 1 ou du récipient de cuisson et elle permet de repérer la position d'un rayon optique incident sur celle-ci.The Figures 3 and 4 represent a variant of the electrical appliance system in which the appliance 1 or the cooking vessel or the induction table 2 comprises a device for measuring the decentering of the first optical device 4 with respect to the second optical device 5 or the second optical device 5 by relative to the first optical device 4. The device for measuring the decentering comprises a slab 9 photosensitive to optical rays. It is positioned on the induction table 2 or on the bottom of the appliance 1 or the cooking vessel and it makes it possible to locate the position of an optical ray incident thereon.

Le dispositif de mesure du décentrage est relié à un dispositif d'affichage 16 de la position du rayon incident sur la dalle 9 photosensible qui permet de visualiser les positions relatives des deux dispositifs optiques (4, 5) l'un par rapport à l'autre en temps réel, le second dispositif optique 5 étant fixe par rapport à la table à induction 2 et le premier dispositif optique 4 étant mobile par rapport à la table à induction 2.The decentering measuring device is connected to a display device 16 of the position of the incident ray on the photosensitive plate 9 which makes it possible to visualize the relative positions of the two optical devices (4, 5) relative to one another. another in real time, the second optical device 5 being fixed relative to the induction table 2 and the first optical device 4 being movable relative to the induction table 2.

A partir de cette visualisation, un utilisateur peut corriger l'alignement des deux dispositifs optiques (4, 5) entre eux.From this visualization, a user can correct the alignment of the two optical devices (4, 5) with each other.

D'une manière générale, et comme visible aux figures 1 à 4, l'appareil électroménager 1 ou le récipient de cuisson ou encore la table à induction 2 comprend une interface 14 utilisateur. Cette interface 14 utilisateur est adaptée à recevoir en entrée des données de commande. Cette interface 14 utilisateur comprend des touches tactiles ou électromécaniques. Les informations rentrées sur l'interface 14 utilisateur peuvent commander directement les fonctions de l'élément du système électroménager sur lequel se trouve l'interface 14 utilisateur ou peuvent être transmises par le premier dispositif optique 4 ou par le second dispositif optique 5 à l'autre élément du système électroménager.In general, and as visible to Figures 1 to 4 , the appliance 1 or the cooking vessel or the induction table 2 comprises a user interface 14. This user interface 14 is adapted to receive input control data. This user interface 14 includes tactile or electromechanical keys. The information entered on the user interface 14 can directly control the functions of the element of the electrical household system on which the user interface 14 is located or can be transmitted by the first optical device 4 or by the second optical device 5 to the other element of the household electrical system.

Plusieurs cas de figures peuvent être rencontrés lors de l'utilisation de l'appareil électroménager 1 ou du récipient de cuisson avec la table à induction 2. Tout d'abord aucun appareil électroménager 1 ou récipient de cuisson n'est positionné sur la table à induction 2. Dans ce cas là, le capteur optique du second dispositif optique 5 ne détecte pas de rayons optiques. Le microcontrôleur 13 interprète l'information et le résultat est visualisable sur le dispositif de visualisation 8.Several situations can be encountered when using the appliance 1 or the cooking vessel with the induction cooker 2. Firstly, no appliance 1 or cooking vessel is positioned on the cooking table. In this case, the optical sensor of the second optical device 5 does not detect optical rays. The microcontroller 13 interprets the information and the result is viewable on the display device 8.

Une fois un appareil électroménager 1 ou un récipient de cuisson positionné sur la table à induction 2, les deux dispositifs optiques (4, 5) peuvent être soit alignés soit non alignés.Once a household appliance 1 or a cooking vessel positioned on the induction table 2, the two optical devices (4, 5) can be either aligned or non-aligned.

Si les deux dispositifs optiques (4, 5) ne sont pas alignés, le second dispositif optique 5 de la table à induction 2 va recevoir des rayons optiques issus principalement de la réflexion de ses propres rayons optiques émis sur le fond de l'appareil électroménager 1 ou du récipient de cuisson. Le second dispositif optique 5 est adapté à reconnaitre la puissance des rayons optiques reçus et à en déduire que en dessous d'un certain seuil de puissance des rayons optiques reçus, le premier dispositif optique 4 de l'appareil électroménager 1 ou du récipient de cuisson est décalé par rapport au second dispositif optique 5 de la table à induction 2.If the two optical devices (4, 5) are not aligned, the second optical device 5 of the induction table 2 will receive optical radiation mainly from the reflection of its own optical radiation emitted on the bottom of the appliance. 1 or cooking vessel. The second optical device 5 is adapted to recognize the power of the optical rays received and to deduce that below a certain power threshold of the optical rays received, the first optical device 4 of the household appliance 1 or the cooking vessel is offset from the second optical device 5 of the induction table 2.

La visualisation de ce décalage se fera via le dispositif 16 d'affichage mentionné ci-dessus ou encore via l'afficheur 7 ou encore via les deux à la fois.The display of this shift will be via the display device 16 mentioned above or again via the display 7 or via both at once.

Lorsque les deux dispositifs optiques (4, 5) sont l'un en face de l'autre, les un ou plusieurs rayons optiques 10 émis par le premier dispositif optique 4 sont directement reçus par le second dispositif optique 5. De cette manière le seuil de puissance nécessaire au second dispositif optique 5 pour détecter le bon alignement du premier dispositif optique 4 est atteint. L'afficheur 7 indique maintenant par un changement d'état des diodes que les deux dispositifs optiques (4, 5) sont alignés et le dispositif 16 d'affichage indique quant à lui le bon alignement, par exemple, par la superposition d'un point lumineux au centre d'un référentiel en forme de croix.When the two optical devices (4, 5) are opposite each other, the one or more optical rays 10 emitted by the first optical device 4 are directly received by the second optical device 5. In this way the threshold necessary power to the second optical device 5 to detect the proper alignment of the first optical device 4 is achieved. The display 7 now indicates by a change of state of the diodes that the two optical devices (4, 5) are aligned and the display device 16 indicates the proper alignment, for example, by the superposition of a luminous point in the center of a cross-shaped reference frame.

Une fois l'alignement effectué, un échange de données bidirectionnel peut se faire et la commande de la table à induction 2 est possible soit via l'appareil électroménager 1 ou le récipient de cuisson, soit directement via la table à induction 2 et dans un cas comme dans l'autre via l'interface 14 utilisateur qui permet de rentrer des données de commande.Once the alignment is completed, a two-way data exchange can be done and the control of the induction table 2 is possible either via the appliance 1 or the cooking vessel, or directly via the induction table 2 and in a case as in the other via the user interface 14 which allows to enter control data.

Par exemple dans ce cas de figure, un utilisateur peut commander la puissance de chauffe de la table à induction 2 par l'intermédiaire de l'appareil électroménager 1 ou du récipient de cuissonFor example in this case, a user can control the heating power of the induction table 2 through the appliance 1 or the cooking vessel

On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées au mode de réalisation de l'invention décrit dans la présente description sans sortir du cadre de l'invention défini par les revendications annexées.It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the embodiment of the invention described in the present description without departing from the scope of the invention defined by the appended claims.
