Titre de l'invention : Robot de cuisson autoalimenté Title of the invention: Self-powered cooking robot
[0001 ] DOMAINE DE L'INVENTION AUQUEL SE RAPPORTE L'INVENTION[0001] FIELD OF THE INVENTION TO WHICH THE INVENTION RELATES
[0002] L’invention concerne le domaine des robots de cuisson au sein de la famille des robots de cuisine. The invention relates to the field of cooking robots within the family of kitchen robots.
ART ANTERIEUR PRIOR ART
[0003] Dans le domaine des appareils électroménagers, il existe des robots de cuisine de plusieurs sortes suivant qu’ils intègrent ou non la fonction de cuisson. In the field of household appliances, there are kitchen robots of several kinds depending on whether or not they integrate the cooking function.
[0004] Les modèles qui intègrent la fonction de cuisson sont en général plus sophistiqués et plus encombrants. [0004] The models which incorporate the cooking function are generally more sophisticated and bulkier.
[0005] Ces modèles viennent souvent en complément dans une cuisine bien équipée avec four et table de cuisson déjà utilisés au quotidien. [0005] These models often complement a well-equipped kitchen with an oven and a hob that are already in daily use.
[0006] De ce fait, le robot de cuisson apparait particulièrement encombrant quand il n’est pas utilisé. [0006] As a result, the cooking robot appears particularly cumbersome when it is not in use.
[0007] Le brevet EP3685718 propose un concept général d’exploitation de l’énergie générée par une bobine d’induction d’une part pour la cuisson et d’autre part pour entraîner les dispositifs de type mélange. [0007] Patent EP3685718 proposes a general concept for exploiting the energy generated by an induction coil on the one hand for cooking and on the other hand for driving mixing-type devices.
[0008] Cependant ce brevet ne détaille pas le fonctionnement de la partie cuisson, mais uniquement l’accouplement magnétique pour transmettre un couple sans passer par une fonction transformateur électrique. [0008] However, this patent does not detail the operation of the cooking part, but only the magnetic coupling to transmit torque without going through an electrical transformer function.
[0009] BREVE DESCRIPTION DE L'INVENTION [0009] BRIEF DESCRIPTION OF THE INVENTION
[0010] Le robot de cuisson comportant un bol mélangeur (BM) selon l’invention ne comporte pas d’élément chauffant pour chauffer le bol mélangeur, la fonction cuisson étant réalisée par une plaque de cuisson indépendante à induction positionnée sous le bol (BM). The cooking robot comprising a mixing bowl (BM) according to the invention does not comprise a heating element for heating the mixing bowl, the cooking function being performed by an independent induction hob positioned under the bowl (BM ).
[0011] Pour cela le bol a un fond plat, ce fond plat comporte une couche magnétique et le fond plat est surélevé par rapport au niveau inférieur du robot correspondant au niveau de la surface de la plaque de cuisson. For this the bowl has a flat bottom, this flat bottom has a magnetic layer and the flat bottom is raised relative to the lower level of the robot corresponding to the level of the surface of the hob.
[0012] Il comporte à sa base un matériau magnétique doux pour canaliser le flux magnétique sans réchauffement lié aux courants de Foucault. It comprises at its base a soft magnetic material to channel the magnetic flux without heating related to eddy currents.
[0013] Pour cela, le matériau magnétique du robot de cuisson est réparti entre un partie centrale et une partie périphérique en regard de la bobine d’induction. [0013] For this, the magnetic material of the cooking robot is distributed between a central part and a peripheral part facing the induction coil.
[0014] De façon préférentielle, pour éviter la transmission de chaleur, le matériau magnétique doux est espacé du fond par un entrefer. [0014] Preferably, to avoid the transmission of heat, the soft magnetic material is spaced from the bottom by an air gap.
[0015] En complément de la fonction cuisson, il est avantageux que le robot de cuisson soit alimenté pour la partie hors cuisson par une deuxième bobine d’induction de la plaque de cuisson via une troisième bobine d’induction intégrée au robot de cuisson. [0016] Par sécurité, cette troisième bobine d’induction comporte un écran magnétique pour canaliser le flux magnétique de la deuxième bobine d’induction vers la troisième bobine d’induction intégrée au robot de cuisson et éviter qu’elle irradie l’intérieur du robot comportant son électronique ainsi que l’extérieur vis-à-vis de l’utilisateur. [0015] In addition to the cooking function, it is advantageous for the cooking robot to be powered for the non-cooking part by a second induction coil of the cooking plate via a third induction coil integrated into the cooking robot. [0016] For safety, this third induction coil includes a magnetic screen to channel the magnetic flux from the second induction coil to the third induction coil integrated into the cooking robot and to prevent it from irradiating the interior of the robot comprising its electronics as well as the exterior vis-à-vis the user.
[0017] Ainsi le robot de cuisson est entièrement autoalimenté électriquement par les deux bobines d’induction de la plaque de cuisson à induction [0017] Thus the cooking robot is fully self-powered electrically by the two induction coils of the induction hob
[0018] Dans un dernier mode de réalisation, la motorisation du robot de cuisson n’est pas placée en partie supérieure mais en partie inférieure. Pour cela, à la base du robot de cuisson, l’axe du malaxeur est entraîné par une courroie dans une épaisseur de quelques centimètres, elle-même entraînée par un moteur électrique. In a final embodiment, the motorization of the cooking robot is not placed in the upper part but in the lower part. For this, at the base of the cooking robot, the axis of the mixer is driven by a belt in a thickness of a few centimeters, itself driven by an electric motor.
[0019] A noter que le robot de cuisson comportant un bol mélangeur selon l’invention ne comporte pas d’élément chauffant pour chauffer le bol mélangeur, notamment pas d’élément chauffant électrique tel qu’une résistance chauffante ou un dispositif de cuisson à induction intégré au robot de cuisson. [0019] Note that the cooking robot comprising a mixing bowl according to the invention does not comprise a heating element for heating the mixing bowl, in particular no electric heating element such as a heating resistor or a cooking device with induction built into the cooking robot.

[0024] [Fig.4] shows a cooking robot according to the invention whose cooking function is performed by an independent induction cooking plate positioned under a raised mixing bowl and whose mixing axis is driven by a belt itself even driven by an electric motor.
DESCRIPTION DETAILLEE DE L’INVENTION DETAILED DESCRIPTION OF THE INVENTION
[0025] Le robot de cuisson (R) comportant un bol mélangeur (BM) selon l’invention ne comporte pas d’élément chauffant pour chauffer le bol mélangeur (BM), la fonction cuisson étant réalisée par une plaque de cuisson (PC) indépendante à induction positionnée sous le bol (BM). [0025] The cooking robot (R) comprising a mixing bowl (BM) according to the invention does not does not include a heating element to heat the mixing bowl (BM), the cooking function being performed by an independent induction cooking plate (PC) positioned under the bowl (BM).
[0026] Pour cela le bol (BM) a un fond (F) plat, ce fond (F) plat comporte une couche magnétique (Fl) et le fond plat (F) est surélevé par rapport au niveau inférieur du robot correspondant au niveau de la surface de la plaque de cuisson (PC). For this the bowl (BM) has a flat bottom (F), this flat bottom (F) comprises a magnetic layer (Fl) and the flat bottom (F) is raised relative to the lower level of the robot corresponding to the level surface of the cooking plate (PC).
[0027] Il comporte à sa base un matériau magnétique (M) doux pour canaliser le flux magnétique sans réchauffement lié aux courants de Foucault. It comprises at its base a soft magnetic material (M) to channel the magnetic flux without heating linked to eddy currents.
[0028] Pour cela, le matériau magnétique du robot de cuisson est réparti entre un partie centrale et une partie périphérique en regard de la bobine d’induction (BI). For this, the magnetic material of the cooking robot is distributed between a central part and a peripheral part facing the induction coil (BI).
[0029] De façon préférentielle, pour éviter la transmission de chaleur, le matériau magnétique doux est espacé du fond (F) par un entrefer. Preferably, to avoid heat transmission, the soft magnetic material is spaced from the bottom (F) by an air gap.
[0030] Le robot de cuisson (R) comporte une fonction cuisson par une plaque de cuisson (PC) indépendante à induction, positionnée sous un bol (BM). [0030] The cooking robot (R) comprises a cooking function by means of an independent induction hob (PC), positioned under a bowl (BM).
[0031] Comme illustré [Fig.l], le fond du bol (BM) du robot de cuisson est directement posé sur un emplacement de la plaque de cuisson à induction. [0031] As illustrated [Fig.l], the bottom of the bowl (BM) of the cooking robot is placed directly on a location of the induction hob.
[0032] A noter que dans ce cas illustré [Fig.l], la motorisation de l’axe mélangeur, l’affichage (D) et la commande (C) sont localisés dans la partie supérieure du robot de cuisson (R). Cette partie supérieure peut basculer en appuyant sur le bouton de déverrouillage (V). [0032] Note that in this illustrated case [Fig.l], the motorization of the mixer axis, the display (D) and the control (C) are located in the upper part of the cooking robot (R). This upper part can be tilted by pressing the release button (V).
[0033] Le bol (B) est amovible et vient s’encastrer dans l’embase (E) de façon à bloquer son positionnement en hauteur ainsi qu’en rotation pour équilibrer la force de rotation de l’axe mélangeur. The bowl (B) is removable and fits into the base (E) so as to block its positioning in height as well as in rotation to balance the rotational force of the mixer shaft.
[0034] Dans un mode de réalisation simple, l’embase (E) qui doit résister à la température de la plaque de cuisson (PC) peut être réalisée dans un matériau plastique haute température. In a simple embodiment, the base (E) which must withstand the temperature of the cooking plate (PC) can be made of a high temperature plastic material.
[0035] Ce matériau peut être un matériau plastique ou du silicone compatible de niveau de température de l’ordre de 200°C à 250 °C, matériaux déjà utilisés dans les ustensiles de cuisines actuels, notamment sous forme de joints haute température. This material can be a plastic material or silicone compatible with a temperature level of the order of 200° C. to 250° C., materials already used in current kitchen utensils, in particular in the form of high temperature seals.
[0036] Cette embase (E) peut également être réalisée en métal comme de l’aluminium ou une combinaison des deux, matériau plastique et métal. This base (E) can also be made of metal such as aluminum or a combination of the two, plastic material and metal.
[0037] Le bol (BM) est conçu pour être chauffé par une bobine d’induction (BI) d’une plaque de cuisson (PC) et de ce fait le fond (F) du bol (BM) du robot de cuisson comporte une couche magnétique (Fl). The bowl (BM) is designed to be heated by an induction coil (BI) of a cooking plate (PC) and therefore the bottom (F) of the bowl (BM) of the cooking robot comprises a magnetic layer (Fl).
[0038] Tel que représenté [Fig.l], le fond (F) du bol (BM) 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. [0039] De façon classique; la paroi (P) est métallique exemple en inox non magnétique et le bol (BM) dispose d’un moyen de préhension tel que des oreilles en partie supérieure. As shown [Fig.l], the bottom (F) of the bowl (BM) 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. [0039] Conventionally; the wall (P) is metallic, for example non-magnetic stainless steel, and the bowl (BM) has a gripping means such as lugs in the upper part.
[0040] Selon le mode de réalisation illustré [Fig.1], le fond plat (F) est surélevé par rapport au niveau inférieur du robot correspondant au niveau de la surface de la plaque de cuisson (PC) de façon à limiter le rayonnement en chaleur du fond (F) du bol (BM),According to the illustrated embodiment [Fig.1], the flat bottom (F) is raised relative to the lower level of the robot corresponding to the level of the surface of the cooking plate (PC) so as to limit the radiation in heat from the bottom (F) of the bowl (BM),
[0041] Pour cela le robot de cuisson (R) comporte de préférence à sa base du matériau magnétique (M) capable de canaliser le flux magnétique de la bobine d’induction (BI) vers le fond (F) du bol mélangeur (BM). For this, the cooking robot (R) preferably comprises at its base magnetic material (M) capable of channeling the magnetic flux from the induction coil (BI) towards the bottom (F) of the mixing bowl (BM ).
[0042] Pour cela, le matériau magnétique (M) du robot de cuisson (R) est réparti entre une partie centrale (MC) et une partie périphérique (MP) en regard de la bobine d’induction (BI). For this, the magnetic material (M) of the cooking robot (R) is distributed between a central part (MC) and a peripheral part (MP) facing the induction coil (BI).
[0043] Ce matériau magnétique (M) peut être soit intégré au fond (F) du bol (BM) soit intégré à l’embase (E) de façon fixe. Cette dernière solution est plus intéressante pour intégrer des pieds au fond au fond (F) du bol (BM) dans un matériau non magnétique. This magnetic material (M) can either be integrated into the bottom (F) of the bowl (BM) or integrated into the base (E) in a fixed manner. This last solution is more advantageous for integrating feet at the bottom at the bottom (F) of the bowl (BM) in a non-magnetic material.
[0044] Le robot de cuisson (R) comporte un matériau magnétique doux. Ce matériau magnétique doux canalisera le flux magnétique sans réchauffement lié aux courants de Foucault. The cooking robot (R) comprises a soft magnetic material. This soft magnetic material will channel magnetic flux without eddy current heating.
[0045] De façon préférentielle, pour éviter la transmission de chaleur, le matériau magnétique doux est espacé du fond (F) par un entrefer. Preferably, to avoid heat transmission, the soft magnetic material is spaced from the bottom (F) by an air gap.
[0046] Ces matériaux magnétiques doux sont ceux utilisés dans les transformateurs. These soft magnetic materials are those used in transformers.
[0047] De façon avantageuse, le matériau magnétique doux comporte de la ferrite. Il peut s’agir de ferrite moulée qui peut être fragile ou de ferrite intégrée dans un matériau plastique tel que du plasto-ferrite. Advantageously, the soft magnetic material comprises ferrite. It can be molded ferrite which can be fragile or ferrite integrated in a plastic material such as plasto-ferrite.
[0048] En complément de la fonction cuisson, il est avantageux comme illustré [Fig.2] et [Fig.3] que le robot de cuisson (R) soit alimenté pour la partie hors cuisson par une deuxième bobine d’induction (BI2) de la plaque de cuisson (PC) via une troisième bobine d’induction (B3) intégrée au robot de cuisson. [0048] In addition to the cooking function, it is advantageous as illustrated [Fig.2] and [Fig.3] that the cooking robot (R) is powered for the non-cooking part by a second induction coil (BI2 ) of the cooking plate (PC) via a third induction coil (B3) integrated into the cooking robot.
[0049] Il est possible d’intégrer une bobine d’induction sous le fond (F) du bol (BM) en regard de la bobine d’induction (Bl) pour alimenter également la partie hors cuisson mais dans ce cas l’énergie à prélever serait en concurrence avec l’énergie nécessaire à la cuisson et potentiellement nulle quand la cuisson est à l’arrêt. It is possible to integrate an induction coil under the bottom (F) of the bowl (BM) facing the induction coil (Bl) to also supply the non-cooking part but in this case the energy to be taken would compete with the energy needed for cooking and potentially zero when cooking is stopped.
[0050] Il est privilégié une solution où l’énergie est prélevée sur une deuxième bobine d’induction de fait ayant un réglage de puissance indépendant de la première bobine d’induction (Bl). [0050] A solution is preferred where the energy is taken from a second induction coil in fact having a power setting independent of the first induction coil (B1).
[0051] Pour cela, il est privilégié une troisième bobine d’induction (BI3) ayant une position fermée illustrée [Fig.2] et en position ouverte ajustable illustrée [Fig.3]. For this, a third induction coil (BI3) having a closed position illustrated [Fig.2] and an adjustable open position illustrated [Fig.3] is preferred.
[0052] La position ajustable permet de placer la troisième bobine d’induction (BI3) en regard de la deuxième bobine d’induction (BI3). Usuellement dans le cas d’une plaque d’induction de 60 cm par 60 cm, les centres des 4 bobines d’induction sont espacés de 30 cm. [0052] The adjustable position makes it possible to place the third induction coil (BI3) facing the second induction coil (BI3). Usually in the case of a plate of induction of 60 cm by 60 cm, the centers of the 4 induction coils are spaced 30 cm.
[0053] Par sécurité, cette troisième bobine d’induction (B3) comporte un écran magnétique (S) pour canaliser le flux magnétique de la deuxième bobine d’induction (B 12) vers la troisième bobine d’induction intégrée au robot de cuisson et éviter qu’elle irradie l’intérieur du robot comportant son électronique ainsi que l’extérieur vis-à-vis de l’utilisateur. L’écran magnétique peut avantageusement être réalisé en ferrite. For safety, this third induction coil (B3) comprises a magnetic shield (S) to channel the magnetic flux from the second induction coil (B 12) to the third induction coil integrated into the cooking robot. and prevent it from irradiating the interior of the robot comprising its electronics as well as the exterior vis-à-vis the user. The magnetic screen can advantageously be made of ferrite.
[0054] Par ailleurs, il peut être avantageux d’ajouter une rondelle de métal magnétique au centre et à la base de la bobine d’induction pour leurrer le système de détection de présence d’un ustensile en métal magnétique par la plaque de cuisson (PC). [0054] Furthermore, it may be advantageous to add a magnetic metal washer in the center and at the base of the induction coil to deceive the system for detecting the presence of a magnetic metal utensil by the hob. (CP).
[0055] Le courant recueilli aux bornes de la troisième bobine d’induction (BI3) est un courant alternatif à la fréquence de la bobine d’induction (BI2), typiquement aux alentours de 25 kHz. The current collected at the terminals of the third induction coil (BI3) is an alternating current at the frequency of the induction coil (BI2), typically around 25 kHz.
[0056] L’ensemble des deux bobines (BI2, BI3) se comportent comme un transformateur et la tension reçue peut être de l’ordre de la tension d’alimentation de la bobine si le nombre de spires est analogue. Le courant ainsi alternatif ainsi obtenu peut être redressé par un pont de diodes puis 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. La puissance électrique ainsi transmise est sous la forme d’une tension continue aux bornes d’une forte capacité. The set of two coils (BI2, BI3) behave like a transformer and the voltage received can be of the order of the supply voltage of the coil if the number of turns is similar. The alternating current thus obtained can be rectified by a diode bridge and then 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. The electrical power thus transmitted is in the form of a DC voltage across the terminals of a high capacitance.
[0057] Ainsi le robot de cuisson (R) est entièrement autoalimenté électriquement par les deux bobines d’induction (BI1, BI2) de la plaque de cuisson (PC) à induction. Thus the cooking robot (R) is fully electrically self-powered by the two induction coils (BI1, BI2) of the induction cooking plate (PC).
[0058] Dans un dernier mode de réalisation illustré [Fig.4], la motorisation du robot de cuisson (R) n’est pas placée en partie supérieure mais en partie inférieure. Pour cela, à la base du robot de cuisson (R), l’axe du malaxeur (A) est entraîné par une courroie (B) dans une épaisseur de quelques centimètres, elle-même entraînée par un moteur électrique (M). In a last illustrated embodiment [Fig.4], the motorization of the cooking robot (R) is not placed in the upper part but in the lower part. For this, at the base of the cooking robot (R), the axis of the mixer (A) is driven by a belt (B) in a thickness of a few centimeters, itself driven by an electric motor (M).
[0059] Le bol (BM) étant généralement amovible, l’axe (A) l’est également et vient s’encastrer dans un élément récepteur en rotation. The bowl (BM) being generally removable, the shaft (A) is also removable and fits into a rotating receiving element.
[0060] Tel que représenté, la périphérie de l’élément en rotation est cranté et entrainé par une courroie crantée, elle-même entraînée par un moteur électrique (M) désaxé. La partie magnétique périphérique (MP) est percée en deux endroits pour laisser passer la courroie (B). As shown, the periphery of the rotating element is notched and driven by a toothed belt, itself driven by an off-axis electric motor (M). The peripheral magnetic part (MP) is drilled in two places to allow the belt (B) to pass.
[0061] La partie (MC) canalisant le flux central de la bobine d’induction (BI) peut être réalisé par l’axe A lui-même si il est en matériau magnétique ou par l’élément récepteur en rotation si il est en matériau magnétique. Application industrielle The part (MC) channeling the central flux of the induction coil (BI) can be produced by the axis A itself if it is made of magnetic material or by the rotating receiving element if it is made of magnetic material. Industrial application
[0062] En termes d’application industrielle, l’invention concerne les robots de cuisson au sein de la famille des robots de cuisine. In terms of industrial application, the invention relates to cooking robots within the family of kitchen robots.
[0063] 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.
