Titre de l'invention : Ustensile de cuisine alimenté par plaque de cuisson à induction Title of Invention: Induction Cooktop Powered Kitchen Utensil
[0001 ] DOMAINE DE L'INVENTION AUQUEL SE RAPPORTE L'INVENTION[0001] FIELD OF THE INVENTION TO WHICH THE INVENTION RELATES
[0002] L’invention concerne dans le domaine des ustensiles de cuisine ou des récipients pour plaque de cuisson à induction, leur alimentation électrique. The invention relates in the field of kitchen utensils or containers for induction hob, their power supply.
ART ANTERIEUR PRIOR ART
[0003] Dans le cas d’un appareil de cuisson comportant une plaque ou plusieurs plaques à induction, la création de chaleur se fait par le champ magnétique qui échauffe les éléments magnétiques tel que de l’inox magnétique présent dans l’ustensile de cuisine ou le récipient. In the case of a cooking appliance comprising a plate or several induction plates, the creation of heat is done by the magnetic field which heats the magnetic elements such as magnetic stainless steel present in the kitchen utensil or the container.
[0004] Tel que représenté [Fig.1], le fond (F) de l’ustensile de cuisine ou du récipient en l’occurrence une poêle, comporte plusieurs couches. La première couche (Fl) est une couche d’inox magnétique qui va créer la chaleur, la deuxième couche (F2) est une couche d’aluminium qui va diffuser la chaleur créée, la troisième couche (F3) va être en contact avec l’aliment et sera en inox non magnétique. As shown [Fig.1], the bottom (F) of the kitchen utensil or container, in this case a pan, has several layers. The first layer (Fl) is a layer of magnetic stainless steel which will create the heat, the second layer (F2) is a layer of aluminum which will diffuse the heat created, the third layer (F3) will be in contact with the food and will be made of non-magnetic stainless steel.
[0005] La bobine d’induction (BI) va générer un champ électromagnétique qui va échauffer par courant de Foucault les éléments magnétiques en l’occurrence la couche (Fl). The induction coil (BI) will generate an electromagnetic field which will heat the magnetic elements by eddy current, in this case the layer (Fl).
[0006] Les ustensiles de cuisine ou récipients pour plaque de cuisson sont usuellement dépourvus d’électronique ou d’accessoire électriques. [0006] Kitchen utensils or containers for a hob are usually devoid of electronics or electrical accessories.
[0007] Si c’était le cas il serait possible pour des puissances faibles de quelques watt de les alimenter par une pile et pour des puissances supérieures de les alimenter sur le secteur en courant alternatif 50 Hz 220 volts ou autre en fonction des pays. [0007] If this were the case, it would be possible for low powers of a few watts to supply them with a battery and for higher powers to supply them from the mains in alternating current 50 Hz 220 volts or other depending on the country.
[0008] La solution des piles présente l’inconvénient de sa dimension et de la nécessité de remplacer les piles, ainsi donc également de la nécessité d’un boitier et d’un couvercle. [0008] The battery solution has the disadvantage of its size and the need to replace the batteries, and therefore also the need for a box and a cover.
[0009] La solution d’alimentation par secteur présente l’inconvénient de la présence du cordon secteur sur la table de cuisson. [0009] The mains power solution has the disadvantage of the presence of the mains cord on the hob.
[0010] Il est également possible comme illustré [Fig.2] d’intégrer une bobine d’induction dans le fond de l’ustensile de cuisine. [0010] It is also possible as illustrated [Fig.2] to integrate an induction coil in the bottom of the kitchen utensil.
[0011] Une telle solution est décrite dans le brevet WO2013007953. [0011] Such a solution is described in patent WO2013007953.
[0012] Une telle intégration de la bobine de réception dans le fond de l’ustensile de cuisine ou du récipient conduit à ce qu’elle soit très exposée d’un point de vue mécanique et thermique, notamment avec de fortes contraintes de dilations différentielles lors des variations brusques de température inévitables en cours d’utilisation. Such integration of the receiving coil in the bottom of the kitchen utensil or container leads to it being very exposed from a mechanical and thermal point of view, in particular with high differential expansion stresses during sudden temperature changes that are inevitable during use.
[0013] BREVE DESCRIPTION DE L'INVENTION [0013] BRIEF DESCRIPTION OF THE INVENTION
[0014] L’ustensile de cuisine ou récipient pour plaque de cuisson à induction selon l’invention comporte au moins une bobine à induction. [0014] The kitchen utensil or container for an induction hob according to the invention comprises at least one induction coil.
[0015] Selon l’invention, la bobine de réception n’est pas intégrée comme classiquement dans le fond de l’ustensile de l’ustensile de cuisine ou du récipient. According to the invention, the receiving coil is not integrated as conventionally in the bottom of the utensil of the kitchen utensil or of the container.
[0016] Pour cela la paroi (P) de l’ustensile de cuisine ou du récipient (U) n’est pas en matériau magnétique et il ne faut pas qu’une couche magnétique couvre l’intégralité de la surface du fond. [0016] For this, the wall (P) of the kitchen utensil or container (U) is not made of magnetic material and a magnetic layer must not cover the entire surface of the bottom.
[0017] Cette bobine à induction de réception capte l’énergie d’une plaque de cuisson (PC) à induction sur laquelle est posée l’ustensile de cuisine ou récipient pour plaque de cuisson à induction, en étant positionnée de façon avantageuse au niveau de la paroi, à l’intérieur ou à proximité de cette paroi. This reception induction coil captures the energy of an induction hob (PC) on which the kitchen utensil or container for an induction hob is placed, being advantageously positioned at the level of the wall, inside or near this wall.
[0018] Selon un mode de réalisation, au moins une bobine à induction de réception a des spires réparties angulairement sur un secteur d’angle. According to one embodiment, at least one receiving induction coil has turns distributed angularly over a corner sector.
[0019] Selon un mode de réalisation, au moins une bobine d’induction de réception est intégrée dans la paroi de l’ustensile de cuisine ou récipient mais elle peut être également intégrée dans un cerclage de l’ustensile de cuisine ou du récipient. According to one embodiment, at least one reception induction coil is integrated into the wall of the kitchen utensil or container, but it can also be integrated into a strapping of the kitchen utensil or container.
[0020] Dans ce dernier cas, il peut être avantageux qu’au moins une bobine d’induction de réception soit réalisée sur circuit imprimé souple. [0020] In the latter case, it may be advantageous for at least one receiving induction coil to be produced on a flexible printed circuit.
[0021] En termes d’exploitation, la bobine d’induction de réception permet d’alimenter un circuit électronique basse tension. [0021] In terms of operation, the reception induction coil makes it possible to supply a low-voltage electronic circuit.
[0022] De façon privilégiée, le circuit électronique basse tension est intégré dans le moyen de préhension de l’ustensile de cuisine ou du récipient. [0022] Preferably, the low-voltage electronic circuit is integrated into the gripping means of the kitchen utensil or container.
[0023] Pour les modèles les plus sophistiqués, il devient possible d’établir une communication bidirectionnelle entre l’électronique de la plaque de cuisson et l’électronique de l’ustensile de cuisine ou du récipient. [0023] For the most sophisticated models, it becomes possible to establish two-way communication between the electronics of the hob and the electronics of the kitchen utensil or container.

[0027] [Fig.3] shows a pan for an induction hob according to the invention comprising a low-power receiving induction coil integrated near its wall.
DESCRIPTION DETAILLEE DE L’INVENTION DETAILED DESCRIPTION OF THE INVENTION
[0028] E'ustensile de cuisine ou récipient (U) pour plaque de cuisson à induction selon l'invention, comporte au moins une bobine à induction. [0028] Kitchen utensil or container (U) for induction hob according to the invention comprises at least one induction coil.
[0029] Cette bobine à induction est conçue pour être une bobine à induction de réception pour capter l'énergie d'une plaque de cuisson à induction émise par une bobine d'induction de celle-ci. This induction coil is designed to be a receiving induction coil to capture the energy of an induction hob emitted by an induction coil thereof.
[0030] Selon l’invention, la bobine de réception est intégrée non pas comme classiquement dans le fond de l’ustensile de cuisine mais au niveau de la paroi, à l’intérieur ou à proximité de cette paroi. According to the invention, the receiving coil is integrated not as conventionally in the bottom of the kitchen utensil but at the level of the wall, inside or close to this wall.
[0031] Selon un mode de réalisation illustré [Fig.3], la bobine à induction de réception (BR) est une bobine plate rectangulaire de l'ordre de 16 spires d'un fil de Litz d'environ 1 millimètre de diamètre intégrée ou à proximité de la paroi (P). According to an illustrated embodiment [Fig.3], the reception induction coil (BR) is a rectangular flat coil of the order of 16 turns of a Litz wire of about 1 millimeter in diameter integrated or close to the wall (P).
[0032] Pour que cette bobine à induction de réception (BR) puisse capter de l’énergie émise par la bobine d’induction (BI) de la plaque de cuisson il faut d’une part que la paroi (P) ne soit pas en matériau magnétique, par exemple en aluminium ou en inox non magnétique et d’autre part que la couche magnétique (Fl) ne couvre pas l’intégralité de la surface du fond (F). [0032] In order for this reception induction coil (BR) to be able to capture the energy emitted by the induction coil (BI) of the hob, it is necessary on the one hand that the wall (P) is not made of magnetic material, for example aluminum or non-magnetic stainless steel, and secondly that the magnetic layer (F1) does not cover the entire bottom surface (F).
[0033] A cette fin, la couche de matériau magnétique (Fl) n’est présente qu’à l’emplacement des six rectangles représentés en pointillés sur la [Fig.2]. To this end, the layer of magnetic material (Fl) is only present at the location of the six rectangles shown in dotted lines in [Fig.2].
[0034] Il faut en effet suffisamment de présence de matériau magnétique (Fl) pour chauffer le fond (D) de l'ustensile de cuisine ou du récipient (U) et pour qu’il soit détecté par la détection de présence d’un ustensile de cuisine de la plaque de cuisson (PC) [0034] In fact, sufficient presence of magnetic material (F1) is required to heat the bottom (D) of the kitchen utensil or of the container (U) and for it to be detected by detecting the presence of a cooker utensil (pc)
[0035] Dans cette configuration, l’énergie captée par la bobine d’induction de réception (BR) ne va pas être uniforme en fonction de l’orientation angulaire sur 360°. In this configuration, the energy picked up by the reception induction coil (BR) will not be uniform depending on the angular orientation over 360°.
[0036] Il est alors préférable que l’ustensile de cuisine ou récipient (U) comporte une pluralité de bobines à induction de réception (BR). It is then preferable for the kitchen utensil or container (U) to comprise a plurality of receiving induction coils (BR).
[0037] Ces bobines à induction de réception (BR) sont réparties angulairement sur 360°. These reception induction coils (BR) are angularly distributed over 360°.
[0038] En alternative comme représenté [Fig.3], il est possible d’utiliser au moins une bobine dont des spires réparties angulairement sur un secteur d’angle. Alternatively, as shown [Fig.3], it is possible to use at least one coil whose turns are distributed angularly over a corner sector.
[0039] Ce ou ces bobines d’induction de réception peuvent être physiquement intégrées dans l’épaisseur de la paroi (P) mais il est également possible de les intégrer dans un cerclage de l’ustensile de cuisine ou récipient (U). This or these reception induction coils can be physically integrated into the thickness of the wall (P) but it is also possible to integrate them into a strapping of the kitchen utensil or container (U).
[0040] Il reste possible de réaliser cette bobine ou ces bobines d’induction en réception (BR) sous forme de circuit imprimé souple tel que des supports en polyamide ou kapton. [0040] It remains possible to produce this reception coil or these induction coils (BR) in the form of a flexible printed circuit such as polyamide or kapton supports.
[0041] L’énergie captée est de quelques watts. The energy captured is a few watts.
[0042] Le courant recueilli aux bornes de la bobine d’induction (BR) est un courant alternatif à la fréquence de la bobine d’induction (BI), typiquement aux alentours de 25 kHz. The current collected at the terminals of the induction coil (BR) is an alternating current at the frequency of the induction coil (BI), typically around 25 kHz.
[0043] L’ensemble des deux bobines (BI, BR) se comportent comme un transformateur et la tension reçue peut être de l’ordre de quelques volts. [0044] Le courant alternatif ainsi obtenu peut être directement exploité à titre d’exemple pour visualiser la puissance de la plaque de cuisson à destination de l’utilisateur. Cela peut prendre la forme d’une intensité d’une ampoule, du déplacement d’une aiguille, de la rotation d’un élément. The set of two coils (BI, BR) behave like a transformer and the voltage received can be of the order of a few volts. The alternating current thus obtained can be directly exploited by way of example to visualize the power of the hob for the user. This can take the form of the intensity of a bulb, the movement of a needle, the rotation of an element.
[0045] Le courant alternatif ainsi obtenu peut être également exploité pour alimenter un circuit électronique basse tension. Dans ce cas le courant alternatif doit être redressé par un pont de diodes, stocké dans une forte capacité pour absorber pour la plupart des modèles la modulation cyclique utilisée par la plaque de cuisson pour moduler la puissance de la bobine d’induction en fonction du réglage effectué par l’utilisateur. The alternating current thus obtained can also be used to supply a low voltage electronic circuit. In this case the alternating current must be rectified by a diode bridge, stored in a high capacity to absorb for most models the cyclic modulation used by the hob to modulate the power of the induction coil according to the setting performed by the user.
[0046] La puissance électrique ainsi transmise est sous la forme d’une tension continue aux bornes d’une capacité permet d’alimenter alors un régulateur de tension, voire une simple diode zener pour produire la tension stabilisée nécessaire au circuit électronique. The electrical power thus transmitted is in the form of a DC voltage at the terminals of a capacitor then makes it possible to supply a voltage regulator, or even a simple zener diode to produce the stabilized voltage necessary for the electronic circuit.
[0047] Le circuit électronique peut par exemple afficher la température du fond de la poêle (U) mesurée par une thermistance, c’est-à-dire par une résistance à coefficient de température positif ou négatif ou par un thermocouple. The electronic circuit can for example display the temperature of the bottom of the pan (U) measured by a thermistor, that is to say by a resistor with a positive or negative temperature coefficient or by a thermocouple.
[0048] Il permettra également d’afficher la vitesse d’échauffement difficilement appréciable dans le cas d’une plaque de cuisson à induction contrairement par exemple à une gazinière où l’utilisateur visualise directement le réglage de la puissance du gaz. [0048] It will also make it possible to display the heating rate, which is difficult to assess in the case of an induction hob, unlike for example a gas cooker where the user directly visualizes the adjustment of the gas power.
[0049] De préférence l’électronique sera déportée dans le moyen de préhension de l’ustensile de cuisine ou du récipient (U) qui reste généralement à basse température, en l’occurrence comme illustré [Fig.3] dans le manche de la poêle (U) avec sa commande (C) et son afficheur (D). Preferably the electronics will be remote in the gripping means of the kitchen utensil or the container (U) which generally remains at low temperature, in this case as illustrated [Fig.3] in the handle of the stove (U) with its control (C) and its display (D).
[0050] De façon avantageuse, le moyen de préhension sera amovible et connecté au reste de l’appareil de cuisson par un connecteur comportant a minima les deux bornes de la bobine d’induction de réception (BR), et par exemple en cas de mesure de la température aux deux bornes de la thermistance. Advantageously, the gripping means will be removable and connected to the rest of the cooking appliance by a connector comprising at least the two terminals of the reception induction coil (BR), and for example in the event of measurement of the temperature at the two terminals of the thermistor.
[0051] Ainsi l’électronique sera moins exposée et n’aura pas à résister aux conditions de lavage d’un lave- vaisselle contrairement au reste de l’ustensile de cuisine ou récipient (U) qui lui peut passer au lave-vaisselle. [0051] Thus the electronics will be less exposed and will not have to withstand the washing conditions of a dishwasher unlike the rest of the kitchen utensil or container (U) which can be washed in the dishwasher.
Application industrielle Industrial application
[0052] En termes d’application industrielle, l’invention s’applique à l’alimentation électrique des ustensiles de cuisine ou des récipients pour plaque de cuisson à induction. In terms of industrial application, the invention applies to the power supply of kitchen utensils or containers for induction hobs.
[0053] La présente invention n'est nullement limitée aux modes de réalisation décrits et représentés mais l'homme du métier saura y apporter toute variante conforme à son esprit pour une gamme de produits dans différents domaines. The present invention is in no way limited to the embodiments described and represented, but a person skilled in the art will know how to make any variant in accordance with his spirit for a range of products in different fields.
