EOUR A MICRO-ONDES A PLATEAU
BRASSEUR D'ONDES
La présente invention concerne un four à micro-ondes à plateau brasseur d'ondes.MICROWAVE TRAY EOUR
WAVE BREAKER
The present invention relates to a microwave oven with a wave brewer tray.
Dans un four à micro-ondes, les micro-ondes généralement produites par un magnétron sont amenées par un guide d'ondes dans une enceinte de traitement où est entreposé un produit soumis à une cuisson, un réchauffage ou une déeongèlation. Dans leur état stationnaire dans cette enceinte, les micro-ondes opèrent leur traitement. Si un produit soumis à un traitement dans cette enceinte est maintenu immobile, on constate que certaines parties de ce produit sont réchauffées et d'autres parties de celui-ci restent relativement froides, autrement dit le réchauffage ou la cuisson de ce produit n'est pas uniforme. In a microwave oven, the microwaves generally produced by a magnetron are brought by a waveguide into a processing enclosure where a product subjected to cooking, reheating or defrosting is stored. In their stationary state in this enclosure, the microwaves operate their processing. If a product subjected to a treatment in this enclosure is kept stationary, it is found that certain parts of this product are reheated and other parts of it remain relatively cold, in other words the reheating or cooking of this product is not uniform.
Selon une solution connue, pour pallier cet inconvénient, le produit est rendu mobile dans cette enceinte afin de varier ltexposition de ses parties aux micro-ondes. On le dispose par exemple sur un plateau tournant transparent aux micro-ondes. Le résultat de réchauffage ou de cuisson de ce produit se révèle amélioré, mais reste non uniforme. En effet, on trouve dans la masse de ce produit au lieu d'une alternance de zones ponctuelles chaudes et froides ou tièdes, une imbrication de zones circulaires chaudes et froides ou tièdes. According to a known solution, to overcome this drawback, the product is made mobile in this enclosure in order to vary the exposure of its parts to microwaves. It is for example placed on a turntable transparent to microwaves. The reheating or cooking result of this product appears to be improved, but remains non-uniform. Indeed, we find in the mass of this product instead of an alternation of hot and cold or lukewarm point areas, an interweaving of hot and cold or lukewarm circular areas.
Une autre solution connue prévoit, à la sortie du guide d'ondes, un brasseur d'ondes qui réfléchit de façon aléatoire les micro-ondes dans l'enceinte du four où est disposé un produit.Another known solution provides, at the outlet of the waveguide, a wave stirrer which randomly reflects the microwaves in the oven enclosure where a product is placed.
Le résultat du traitement n'est pas entièrement satisfaisant, car le réchauffage ou la cuisson de ce produit se révèle encore hétérogène dans la masse de ce dernier.The result of the treatment is not entirely satisfactory, since the reheating or cooking of this product still proves to be heterogeneous in the mass of the latter.
La présente invention permet de réaliser un four à micro-ondes économique qui donne un bon résultat de réchauffage ou de cuisson d'un produit disposé dans son enceinte de traitement par un excellent brassage des micro-ondes et par un balayage soigneux de la masse de ce produit par ces micro-ondes. The present invention makes it possible to produce an economical microwave oven which gives a good result of reheating or cooking a product placed in its treatment enclosure by excellent stirring of the microwaves and by careful scanning of the mass of this product by these microwaves.
Selon l'invention, un four à micro-ondes ayant dans son enceinte de traitement un plateau destiné à supporter des produits soumis à un réchauffage ou une cuisson est caractérisé en ce que le plateau qui supporte les produits, refléchit d'une manière aléatoire les micro-ondes tombant sur sa surface. According to the invention, a microwave oven having in its treatment enclosure a tray intended to support products subjected to reheating or cooking is characterized in that the tray which supports the products, randomly reflects the microwave falling on its surface.
Pour mieux faire comprendre l'invention, on en décrit ci-après un exemple de réalisation illustré schématiquement et partiellement par un dessin ci-annexe. To better understand the invention, an embodiment is described below illustrated schematically and partially by an attached drawing.
Un four à micro-ondes 1 illustré comprend une enveloppe 2 dans laquelle sont formés un compartiment 3 pour loger des organes de production de micro-ondes et de commande de four 1 de types connus non représentés et un compartiment 4 servant de caisse de résonance et d'enceinte de traitement du four 1. Les micro-ondes produites dans le compartiment 3 sont amenées par un guide d'ondes 5 dans l'enceinte 4 où est monté un plateau 6 destiné à supporter un produit 7 soumis à un réchauffage ou une cuisson. A microwave oven 1 illustrated comprises a casing 2 in which a compartment 3 is formed to house microwave production and oven control members 1 of known types not shown and a compartment 4 serving as a sounding board and of the oven's treatment enclosure 1. The microwaves produced in the compartment 3 are brought by a waveguide 5 into the enclosure 4 where a tray 6 is mounted for supporting a product 7 subjected to reheating or a cooking.
Selon l'invention, le four à micro-ondes 1 comprend dans son enceinte 4 un plateau 6 réfléchissant aléatoirement les micro-ondes 8 tombant sur sa surface. According to the invention, the microwave oven 1 comprises in its enclosure 4 a plate 6 randomly reflecting the microwaves 8 falling on its surface.
Dans une variation de réalisation, le four à micro-ondes 1 comprend dans son enceinte 4 un plateau 6 à la fois tournant et réfléchissant aléatoirement les micro-ondes 8 tombant sur sa surface. Un réfléchissement aléatoire des micro-ondes permet de complèter ltétat stationnaire des micro-ondes dans l'enceinte 4 par un état aléatoire ou changeant des micro-ondes réfléchies et de réaliser ainsi un bon brassage des micro-ondes tandis qu'un mouvement tournant du plateau G constribue d'une part à varier les angles d'incidence et de réflexion des micro-ondes rencontrant ce plateau 6, favoriser ainsi le caractère aléatoire de leur réfléchissement et renforcer en conséquence le brassage des micro-ondes dans l'enceinte 4, et d'autre part à varier l'orientation des parties du produit exposées aux micro-ondes par conséquent à parfaire le balayage de toute la masse de ce produit par les micro-ondes. In a variant embodiment, the microwave oven 1 comprises in its enclosure 4 a plate 6 both rotating and randomly reflecting the microwaves 8 falling on its surface. A random reflection of the microwaves makes it possible to complete the stationary state of the microwaves in the enclosure 4 by a random or changing state of the reflected microwaves and thus to achieve a good mixing of the microwaves while a rotating movement of the plate G contributes on the one hand to varying the angles of incidence and reflection of the microwaves encountering this plate 6, thus promoting the random nature of their reflection and consequently strengthening the mixing of the microwaves in the enclosure 4, and on the other hand to vary the orientation of the parts of the product exposed to microwaves consequently to perfect the sweeping of the whole mass of this product by microwaves.
Le plateau 6 réfléchissant les micro-ondes est soit réalisé en un métal, un alliage métallique ou un matériau qui réfléchit les micro-ondes, soit formé d'un noyau métallique ou noyau en un matériau réfléchissant les micro-ondes et d'une enveloppe en un matériau transparent aux micro-ondes, soit constitué par un support en un matériau mécaniquement résistant, recouvert d'une couche ou enveloppe métallique ou en un matériau réfléchissant les micro-ondes. The plate 6 reflecting the microwaves is either made of a metal, a metal alloy or a material which reflects the microwaves, or formed of a metal core or core of a material reflecting the microwaves and of an envelope in a material transparent to microwaves, either constituted by a support in a mechanically resistant material, covered with a metallic layer or envelope or in a material reflecting microwaves.
Le plateau 6 réfléchissant les micro-ondes comprend dans sa surface réfléchissante exposée aux micro-ondes des aspérités 10 qui font varier diversement les angles d'incidence et de réflexion des micro-ondes 8 tombant sur cette surface. The plate 6 reflecting the microwaves comprises in its reflecting surface exposed to the microwaves roughnesses 10 which vary the angles of incidence and reflection of the microwaves 8 falling on this surface.
Dans le plateau 6 réfléchisant les micro-ondes 6, les aspérités 10 de sa surface exposée aux micro-ondes sont soit régulières et constituées par des nervures et des rainures uniformes qui sont en alternance régulière entre elles, et/ou par des saisies et des creux uniformes régulièrement espacées, soit irrégulières ou hétérogènes et constituées par des éminences et des dépressions inégales. In the plate 6 reflecting the microwaves 6, the asperities 10 of its surface exposed to the microwaves are either regular and consist of ribs and uniform grooves which are in regular alternation between them, and / or by grips and uniform hollows regularly spaced, either irregular or heterogeneous and formed by uneven eminences and depressions.
La caractéristique de surface du plateau réfléchissant les micro-ondes qui donne au plateau 6 la qualification de plateau brasseur d'ondes peut s'ajouter ou être combinée avec la caractéristique de surface accidentée du plateau et/ou celle de rotation de ce plateau pour renforcer le pouvoir de brassage des micro-ondes par ce plateau 6, parfaire le balayage par les micro-ondes de toute la masse du produit 7 soumis à un traitement dans l'enceinte 4 du four l et atteindre par conséquent une excellente uniformité de réchauffage ou de caisson de ce produit 7. The surface characteristic of the microwave reflective plate which gives the plate 6 the qualification of wave brewing plate can be added or be combined with the uneven surface characteristic of the plate and / or that of rotation of this plate to reinforce the microwave stirring power by this plate 6, perfect the microwave sweeping of the entire mass of the product 7 subjected to a treatment in the enclosure 4 of the oven l and consequently achieve excellent uniformity of reheating or box of this product 7.
Le four à micro-ondes l peut également comporter à la sortie de son guide d'ondes 5 un brasseur d'ondes d'un type connu non représenté. Ce brasseur d'ondes renforce encore l'action du plateau brasseur d'ondes 6 dans le réchauffage ou la cuisson du produit 7 dans l'enceinte 4 du four 1. The microwave oven 1 can also include, at the outlet of its waveguide 5, a wave stirrer of a known type, not shown. This wave brewer further enhances the action of the wave brewer plate 6 in the heating or cooking of the product 7 in the enclosure 4 of the oven 1.
