Description Description
Titre de l'invention : Elément lumineux autoalimenté pour éclairer à l’intérieur d’un four micro-ondes Title of the invention: Self-powered luminous element for illuminating the interior of a microwave oven
[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 appareils de cuisson électriques auquel ap partiennent les fours micro-ondes, un élément lumineux pour éclairer à l’intérieur du four micro-ondes. The invention relates, in the field of electric cooking appliances to which microwave ovens belong, to a luminous element for illuminating the interior of the microwave oven.
ART ANTERIEUR PRIOR ART
[0003] Tel que représenté [Fig.l], un four micro-ondes (MW) comprend usuellement un corps (10) et une porte (11) et l’espace intérieur est de forme sensiblement parallé lépipède rectangle. [0003] As shown [Fig.l], a microwave oven (MW) usually comprises a body (10) and a door (11) and the interior space is of substantially parallel rectangular lepiped shape.
[0004] Pour procéder à la cuisson des aliments solides ou liquides des ondes électroma gnétiques d’une fréquence de l’ordre de quelques gigahertz, typiquement 2450 MHz, sont émises à l’intérieur de cet espace intérieur. [0004] To cook solid or liquid foods, electromagnetic waves with a frequency of the order of a few gigahertz, typically 2450 MHz, are emitted inside this interior space.
[0005] Ces ondes permettent de chauffer et cuire rapidement des aliments, par l'agitation des molécules d'eau qu'ils contiennent, sous l'effet de ce rayonnement électromagnétique. [0005] These waves make it possible to heat and cook food quickly, by agitating the water molecules they contain, under the effect of this electromagnetic radiation.
[0006] Pour protéger l’extérieur de ces ondes électromagnétiques, il faut que cet espace se comporte en une cage de Faraday pour la longueur d’onde émise par le four. To protect the exterior from these electromagnetic waves, this space must behave like a Faraday cage for the wavelength emitted by the oven.
[0007] Pour cette raison le fond du four est en métal ainsi que la porte d’accès (11) qui comporte une fenêtre (12) pour voir l’intérieur du four. [0007] For this reason the bottom of the oven is made of metal as well as the access door (11) which has a window (12) to see the inside of the oven.
[0008] Cette fenêtre (12) comporte une sorte de grille (13) métallique avec des trous dont la dimension est très inférieure à la longueur d’onde du four micro-onde, pour faire obstacle aux ondes dites centimétriques, typiquement 12 cm, du four micro-ondes. This window (12) comprises a kind of metal grid (13) with holes whose size is much lower than the wavelength of the microwave oven, to block the so-called centimetric waves, typically 12 cm, of the microwave oven.
[0009] De ce fait la vision de l’intérieur du four est doublement pénalisée. D’une part la lumière extérieure est en partie bloquée par la grille métallique perforée qui ne laisse passer qu’une partie de la lumière par les trous. D’autre part, la vision de l’intérieur du four micro-ondes est également perturbée par la présence de la grille (13). [0009] As a result, vision of the interior of the oven is doubly penalized. On the one hand, the outside light is partly blocked by the perforated metal grille which only lets part of the light through the holes. On the other hand, the vision of the interior of the microwave oven is also disturbed by the presence of the grid (13).
[0010] Il est possible d’éclairer l’intérieur du four en plaçant un élément lumineux derrière une grille faisant office de cage de Faraday mais ce n’est pas toujours le cas des modèles de fours micro-ondes usuellement commercialisés. [0010] It is possible to illuminate the interior of the oven by placing a luminous element behind a grid acting as a Faraday cage, but this is not always the case with the microwave oven models usually marketed.
[0011] Le brevet W02004113795 décrit un élément lumineux autoalimenté pour four micro ondes mais manifestement l’élément lumineux décrit comporte des éléments mé talliques normalement incompatibles d’un four micro-ondes. De plus ce brevet privilégie d’intégrer dans l’élément lumineux des aimants ferromagnétiques. Sachant que les matériaux ferromagnétiques contiennent des éléments métalliques tels que du fer (usuellement), du nickel et du cobalt ceci qui ne fait qu’accroître la masse des éléments métalliques pourtant proscrits. [0011] Patent WO2004113795 describes a self-powered luminous element for a microwave oven, but clearly the luminous element described comprises metallic elements that are normally incompatible with a microwave oven. In addition, this patent favors integrating ferromagnetic magnets into the luminous element. Knowing that ferromagnetic materials contain metallic elements such as iron (usually), nickel and cobalt, which only increases the mass of metallic elements, however prohibited.
[0012] BREVE DESCRIPTION DE L'INVENTION [0012] BRIEF DESCRIPTION OF THE INVENTION
[0013] L’invention propose au moins un élément lumineux autoalimenté pour éclairer à l’intérieur du four micro-ondes. The invention provides at least one self-powered luminous element to illuminate the interior of the microwave oven.
[0014] Pour cela l’élément lumineux selon l’invention utilise directement les micro-ondes émises normalement et principalement pour les aliments. For this, the luminous element according to the invention directly uses the microwaves emitted normally and mainly for food.
[0015] Cet élément lumineux émet de la lumière du seul fait de l’irradiation d’ondes électro magnétiques centimétriques. De ce fait il émet de la lumière en étant autoalimenté par les ondes électromagnétiques du four micro-ondes sans avoir à être alimenté ou connecté électriquement d’une autre façon. [0015] This luminous element emits light solely due to the irradiation of centimetric electromagnetic waves. As a result, it emits light by being self-powered by the electromagnetic waves of the microwave oven without having to be powered or electrically connected in any other way.
[0016] Pour cela l’élément lumineux utilise la technologie des tubes fluorescents miniatures. [0016] For this, the luminous element uses the technology of miniature fluorescent tubes.
[0017] Par contre les parties métalliques étant déconseillées dans un four micro-ondes, l’élément lumineux comporte le minimum de partie métallique, si possible aucune, en tout cas moins d’un gramme, c’est-à-dire moins qu’un tube fluorescent miniature classique. [0017] On the other hand, the metal parts being inadvisable in a microwave oven, the luminous element comprises the minimum of metal part, if possible none, in any case less than one gram, that is to say less than a classic miniature fluorescent tube.
[0018] Selon un mode de réalisation privilégié, le tube lumineux comporte des éléments mé talliques consistant à chaque extrémité en un filament métallique et deux brins mé talliques, soit au total deux filaments métalliques et quatre brins métalliques re présentant une masse inférieure à 1 gramme. [0018] According to a preferred embodiment, the luminous tube comprises metallic elements consisting at each end of a metallic filament and two metallic strands, i.e. a total of two metallic filaments and four metallic strands having a mass of less than 1 gram. .
[0019] De façon avantageuse, l’élément lumineux comporte une enveloppe hermétique en verre et ces éléments métalliques sont à l’intérieur de l’enveloppe en verre de l’élément lumineux et non accessibles de l’extérieur. Advantageously, the luminous element comprises a hermetic glass envelope and these metal elements are inside the glass envelope of the luminous element and not accessible from the outside.
[0020] Selon un mode de réalisation privilégiée, la forme de l’élément lumineux est un tube d’une section d’un diamètre entre 5 mm et 3 centimètres, par exemple d’un diamètre standard des tubes fluorescents miniatures. According to a preferred embodiment, the shape of the luminous element is a tube with a section with a diameter between 5 mm and 3 centimeters, for example of a standard diameter of miniature fluorescent tubes.
[0021] Notamment si l’élément lumineux selon l’invention est commercialisé sous forme d’accessoire, il est avantageux qu’il dispose de ventouses à ses extrémités. [0021] In particular if the luminous element according to the invention is marketed in the form of an accessory, it is advantageous for it to have suction cups at its ends.
[0022] Bien entendu il est également possible de commercialiser des ustensiles pour fours micro-ondes qui comportent au moins un élément lumineux selon l’invention. [0022] Of course, it is also possible to market utensils for microwave ovens which comprise at least one luminous element according to the invention.
[0023] Bien entendu il est encore également possible de commercialiser des fours micro ondes qui comportent au moins un élément lumineux selon l’invention. Of course, it is still also possible to market microwave ovens which include at least one luminous element according to the invention.
[0024] Dans ce cas, il est privilégié si l’espace intérieur du four micro-ondes est de forme sensiblement parallélépipédique qu’au moins un élément lumineux soit placé paral lèlement et à proximité d’au moins une arête intérieure supérieure du parallélépipède rectangle. [0024] In this case, it is preferable if the interior space of the microwave oven is of substantially parallelepipedic shape that at least one luminous element is placed parallel to and close to at least one upper inner edge of the rectangular parallelepiped .
[0025] En termes d’utilisation, l’élément lumineux éclaire à l’intérieur du four micro-ondes pendant le chauffage ou la cuisson d’aliment. In terms of use, the luminous element illuminates the interior of the microwave oven during heating or cooking of food.
[0026] En fait, l’élément lumineux n’éclaire que lorsque que le four micro-ondes émet des micro-ondes c’est-à-dire de façon synchrone avec l’émission d’ondes du four micro ondes. [0026] In fact, the luminous element only illuminates when the microwave oven emits microwaves, that is to say synchronously with the emission of waves from the microwave oven.
[0027] Dans ce cas, on peut G utiliser pour visualiser le temps de fonctionnement effectif du four micro-ondes. In this case, G can be used to view the effective operating time of the microwave oven.

DESCRIPTION DETAILLEE DE L'INVENTION DETAILED DESCRIPTION OF THE INVENTION
[0034] De façon inédite, l’invention propose au moins un élément lumineux (L) au toalimenté pour éclairer à l’intérieur du four micro-ondes (MW). [0034] In a novel way, the invention proposes at least one luminous element (L) to be powered to illuminate the interior of the microwave oven (MW).
[0035] Pour cela l’élément lumineux (L) selon l’invention utilise directement les micro ondes émises normalement et principalement pour les aliments (A). For this, the luminous element (L) according to the invention directly uses the microwaves emitted normally and mainly for food (A).
[0036] Cet élément lumineux (L) émet de la lumière du seul fait de l’irradiation d’ondes électromagnétiques centimétriques. De ce fait il émet de la lumière en étant au toalimenté par les ondes électromagnétiques du four micro-ondes (MW) sans avoir à être alimenté ou connecté électriquement d’une autre façon. This luminous element (L) emits light solely due to the irradiation of centimetric electromagnetic waves. As a result, it emits light by being powered by the electromagnetic waves of the microwave oven (MW) without having to be powered or electrically connected in any other way.
[0037] Pour cela l’élément lumineux (L) utilise la technologie des tubes fluorescents mi niatures. For this, the luminous element (L) uses the technology of miniature fluorescent tubes.
[0038] Il est en effet possible effectivement d’utiliser des tubes fluorescents miniatures standards. [0038] It is in fact possible to use standard miniature fluorescent tubes.
[0039] Par contre les parties métalliques étant déconseillées dans un four micro-ondes, l’élément lumineux (L) comporte le minimum de partie métallique, si possible aucune, en tout cas moins d’un gramme, c’est-à-dire moins qu’un tube fluorescent miniature classique. [0039] On the other hand, the metal parts being inadvisable in a microwave oven, the luminous element (L) comprises the minimum of metal part, if possible none, in any case less than one gram, that is to say say less than a conventional miniature fluorescent tube.
[0040] En particulier il n’y a pas de raison de conserver les contacts métalliques aux ex- trémités. [0040] In particular, there is no reason to keep the metal contacts at the ex- tremities.
[0041] Selon un mode de réalisation privilégié, illustré [Fig.5] le tube lumineux (L) comporte des éléments métalliques (EM) consistant à chaque extrémité en un filament métallique (F) et deux brins métalliques (B), soit au total deux filaments métalliques (F) et quatre brins métalliques (B) représentant une masse inférieure à 1 gramme. According to a preferred embodiment, illustrated [Fig.5] the luminous tube (L) comprises metallic elements (EM) consisting at each end of a metallic filament (F) and two metallic strands (B), either at total two metal filaments (F) and four metal strands (B) representing a mass of less than 1 gram.
[0042] Fes deux brins métalliques (B) dans ce mode de réalisation consistent en deux conducteurs métalliques sensiblement parallèles d’environ 1 cm reliés par un filament et ce à chaque extrémité. Fes two metal strands (B) in this embodiment consist of two substantially parallel metal conductors of about 1 cm connected by a filament at each end.
[0043] Fes brins métalliques (B) captent le champ magnétique ce qui permet d’exciter le filament (F) sans générer d’arc électrique entre eux à l’extérieur du fait qu’ils sont reliés à l’intérieur par le filament (F). [0043] Fes metal strands (B) pick up the magnetic field which makes it possible to excite the filament (F) without generating an electric arc between them on the outside because they are connected inside by the filament (F).
[0044] De façon avantageuse, l’élément lumineux comporte une enveloppe hermétique en verre et que ces éléments métalliques (EM) sont à l’intérieur de l’enveloppe en verre de l’élément lumineux et non accessibles de l’extérieur. Advantageously, the luminous element comprises a hermetic glass envelope and these metal elements (EM) are inside the glass envelope of the luminous element and not accessible from the outside.
[0045] Selon un mode de réalisation privilégiée, la forme de l’élément lumineux est un tube d’un diamètre entre 5 mm et 3 centimètres, par exemple d’un diamètre standard des tubes fluorescents miniatures. According to a preferred embodiment, the shape of the luminous element is a tube with a diameter between 5 mm and 3 centimeters, for example of a standard diameter of miniature fluorescent tubes.
[0046] Ces diamètres standard sont de 7 mm pour les tubes appelés T2, 16 mm pour les tubes appelés T5 et 26 mm pour les tubes appelés T8. These standard diameters are 7 mm for the tubes called T2, 16 mm for the tubes called T5 and 26 mm for the tubes called T8.
[0047] Il existe également des longueurs standardisées. En particulier en version T5, il existe deux longueurs 142 mm et 217 mm bien adaptées à la dimension d’un four micro ondes. [0047] There are also standardized lengths. In particular in the T5 version, there are two lengths 142 mm and 217 mm well suited to the size of a microwave oven.
[0048] Il existe également des versions de tubes fluorescents miniatures circulaires T5 de section de diamètre 16 mm. There are also versions of T5 circular miniature fluorescent tubes with a diameter section of 16 mm.
[0049] Bien entendu l’élément lumineux (F) n’a pas de contraintes dimensionnelles fortes, mais pour des raisons de synergies industrielles, il reste avantageux de rester dans les dimensions des tubes fluorescents miniatures classiques. Of course, the luminous element (F) has no strong dimensional constraints, but for reasons of industrial synergies, it remains advantageous to remain within the dimensions of conventional miniature fluorescent tubes.
[0050] Si l’élément lumineux (F) selon l’invention est commercialisé sous forme d’accessoire, il est avantageux qu’il dispose de ventouses à ses extrémités. If the luminous element (F) according to the invention is marketed as an accessory, it is advantageous for it to have suction cups at its ends.
[0051] Bien entendu il est également possible de commercialiser des ustensiles pour fours micro-ondes qui comportent au moins un élément lumineux selon l’invention. Of course, it is also possible to market utensils for microwave ovens which include at least one luminous element according to the invention.
[0052] Dans ce cas la forme de l’élément lumineux (E) est adaptée et comme illustré [Fig.4] il peut prendre par exemple la forme d’un cercle partiel de section d’un tube fluorescent miniature standard T5 de section de diamètre 16 mm. In this case the shape of the luminous element (E) is adapted and as illustrated [Fig.4] it can take for example the shape of a partial circle of section of a standard T5 miniature fluorescent tube of section 16mm in diameter.
[0053] Il peut s’agir par exemple de récipients comme des bols, des assiettes, des saladiers ou d’autre ustensiles tels que des cloches qui intègrent de tels éléments lumineux. [0053] These may be, for example, containers such as bowls, plates, salad bowls or other utensils such as cloches which incorporate such luminous elements.
[0054] Bien entendu il est également possible de commercialiser des fours micro-ondes (MW) qui comportent au moins un élément lumineux (F) selon l’invention. [0055] Dans ce cas, il disposera de support par exemple sous forme de fourches flexibles en matériau plastique ce qui permet le démontage pour nettoyer ou changer le ou les éléments lumineux (L). Of course it is also possible to market microwave ovens (MW) which comprise at least one luminous element (F) according to the invention. [0055] In this case, it will have support, for example in the form of flexible forks made of plastic material, which allows dismantling to clean or change the luminous element(s) (L).
[0056] Dans ce cas, il est privilégié si l’espace intérieur du four micro-ondes est de forme sensiblement parallélépipédique qu’au moins un élément lumineux soit placé paral lèlement et à proximité d’au moins une arête intérieure supérieure du parallélépipède rectangle. [0056] In this case, it is preferable if the interior space of the microwave oven is of substantially parallelepipedic shape that at least one luminous element is placed parallel to and close to at least one upper inner edge of the rectangular parallelepiped .
[0057] Ainsi il est possible de disposer de 1 à 3 éléments lumineux (L). Thus it is possible to have 1 to 3 light elements (L).
[0058] Ceci est illustré à la [Fig.2] vu de l’intérieur et en [Fig.3] vu de l’extérieur. [0058] This is illustrated in [Fig.2] seen from the inside and in [Fig.3] seen from the outside.
[0059] Ceci présente l’intérêt de prendre peu de risque d’interférence entre le plat notamment quand il est posé sur un plateau tournant et les éléments lumineux ainsi placés. This has the advantage of taking little risk of interference between the dish, in particular when it is placed on a turntable, and the light elements thus placed.
[0060] Ceci présente également l’intérêt d’éclairer l’aliment (A) du haut vers le bas sur sa face supérieure. This also has the advantage of illuminating the food (A) from top to bottom on its upper face.
[0061] Enfin cela présente enfin l’intérêt que bien que les tubes soient présents dans l’espace intérieur de four micro-ondes (MW) de ne pas aveugler l’utilisateur, la vision directe des tubes étant masquée par les parois de la porte (11) quand par exemple l’utilisateur est dans l’axe de la vue de la [Fig.l]. Finally, this finally has the advantage that although the tubes are present in the interior space of the microwave oven (MW) not to blind the user, the direct vision of the tubes being masked by the walls of the door (11) when for example the user is in line with the view of [Fig.l].
[0062] En termes d’utilisation, l’élément lumineux (L) éclaire à l’intérieur du four micro ondes (MW) pendant le chauffage ou la cuisson d’aliments (A). In terms of use, the luminous element (L) illuminates the interior of the microwave oven (MW) during the heating or cooking of food (A).
[0063] Ceci présente l’intérêt de pouvoir surveiller l’évolution des aliments (A) liquides ou solides pendant le fonctionnement du four micro-ondes (MW). This has the advantage of being able to monitor the evolution of liquid or solid food (A) during the operation of the microwave oven (MW).
[0064] En fait, l’élément lumineux (L) n’éclaire que lorsque que le four micro-ondes (MW) émet des micro-ondes c’est-à-dire de façon synchrone avec l’émission d’ondes du four micro-ondes (MW). In fact, the luminous element (L) only illuminates when the microwave oven (MW) emits microwaves, that is to say synchronously with the emission of waves from the microwave oven (MW).
[0065] C’est-à-dire, que lorsque le four micro-ondes (MW) est en position décongélation ou sur des valeurs inférieures de puissance de fonctionnement, l’émission de micro-ondes sera intermittente et par voie de conséquence l’allumage de l’élément lumineux (L) également. [0065] That is to say, when the microwave oven (MW) is in the defrosting position or at lower operating power values, the emission of microwaves will be intermittent and consequently the lighting of the luminous element (L) also.
[0066] On peut considérer ce fonctionnement intermittent comme un inconvénient. [0066] This intermittent operation can be considered as a disadvantage.
[0067] On peut au contraire le considérer comme un avantage pour visualiser le temps de fonctionnement effectif du four micro-ondes (MW). On the contrary, it can be considered as an advantage for visualizing the effective operating time of the microwave oven (MW).
