Description

La présente invention se rapporte à un dispositif d'entraínement du plateau tournant d'un four à micro-ondes comprenant un moyen fournissant un couple de rotation au plateau tournant, au moins trois roues sur lesquelles le plateau tournant est posé et un support de roues amovible comprenant les axes de rotation desdites roues, lesdits axes étant orientés radialement par rapport au plateau.The present invention relates to a training device turntable of a microwave oven including a means providing a rotational torque to the turntable, at least three wheels on which the turntable is placed and a support of removable wheels comprising the axes of rotation of said wheels, said axes being oriented radially relative to the plate.

Les fours à micro-ondes connus sont généralement munis d'un plateau tournant destiné à recevoir un récipient ou assimilé contenant la nourriture à chauffer. Il existe principalement deux modes d'entraínement de ce plateau qui repose en général sur des roues liées à un support de roues.Known microwave ovens are generally equipped with a turntable for receiving a container or the like containing the food to heat. There are mainly two modes drive this plateau which is usually based on wheels linked to a wheel support.

Dans le premier mode le couple fourni par un moteur est transmis directement au plateau- Le plateau entraíne alors dans son mouvement les roues sur lesquelles il repose et roule. Les roues, elles-mêmes, reposent et roulent sur le fond de la cavité du four à micro-ondes.In the first mode the torque supplied by a motor is transmitted directly to the plateau- The plateau then drives in its movement the wheels on which he rests and rolls. The wheels, themselves, rest and roll on the bottom of the cavity of the microwave oven.

Dans le second mode le couple fourni par un moteur est transmis au support de roues qui, par l'intermédiaire des roues, repose et roule sur le fond de la cavité du four à micro-ondes. La encore, deux types de conceptions sont rencontrées. Soit le plateau repose directement sur le support de roues et a un mouvement identique à celui dudit support. Soit le plateau, comme dans le premier mode, repose sur les roues qui en roulant sur ledit plateau l'entraínent en rotation à une vitesse deux fois plus élevée que celle du support de roues.In the second mode the torque supplied by a motor is transmitted to the support of wheels which, by means of the wheels, rests and rolls on the bottom of the cavity of the microwave oven. The still, two types of designs are encountered. Let the plateau rest directly on the wheel support and has a movement identical to that of said support. Let the plateau, as in the first mode, rests on the wheels which rolling on said plate drive it into rotation at a speed twice that of the medium of wheels.

Ces deux modes de réalisation présentent une contrainte commune: des corps étrangers peuvent venir se loger entre les roues et le fond de la cavité du four à micro-ondes, entraínant des à-coups dans le mouvement de rotation et/ou des patinages des roues. These two embodiments have a constraint common: foreign bodies can come and stay between the wheels and the bottom of the cavity of the microwave oven, causing jolts in the rotational movement and / or wheel slippage.

Une contrainte supplémentaire liée au second mode est celle de devoir positionner le support de roues dans un sens particulier, c'est-à-dire sur la bonne face, et de le positionner de façon à pouvoir l'accoupler correctement au moyen fournissant un couple de rotation au plateau tournant, par la mise en regard de deux méplats ou formes particulières d'entraínement.An additional constraint related to the second mode is that of have to position the wheel support in a particular direction, that is to say on the right side, and to position it so as to able to couple it correctly to the means providing a couple of rotation on the turntable, by facing two flats or special forms of training.

Le but de l'invention est de proposer un support de roues qui se positionne naturellement quels que soient le sens et la position angulaire dans lesquels il est posé sur le fond de la cavité du four à micro-ondes. L'invention se propose d'utiliser un entraínement tel que le premier mode décrit ci-dessus, à savoir que le couple fourni par un moteur est transmis directement au plateau, celui-ci entraínant alors dans son mouvement les roues sur lesquelles il repose et roule.The object of the invention is to propose a wheel support which naturally positions whatever the meaning and position angle in which it is placed on the bottom of the cavity of the oven at microwave. The invention proposes to use a drive such as the first mode described above, namely that the torque provided by a engine is transmitted directly to the plate, which then drives in his movement the wheels on which he rests and rolls.

Le dispositif d'entraínement du plateau tournant d'un four à micro-ondes selon l'invention, en plus d'un moyen fournissant un couple de rotation au plateau tournant, d'au moins trois roues sur lesquelles le plateau tournant est posé et d'un support de roues amovible comprenant les axes de rotation desdites roues, lesdits axes étant orientés radialement par rapport au plateau, comprend des embases montées sur le support de roues amovible, lesdites embases reposant sur le fond de la cavité du four à micro-ondes et assurant l'immobilité du support de roues amovible par rapport à ladite cavité.The device for driving the turntable from a furnace to microwaves according to the invention, in addition to a means providing a rotation torque at turntable, of at least three wheels on which the turntable is placed and a wheel support removable member comprising the axes of rotation of said wheels, said axes being oriented radially with respect to the plate, includes bases mounted on the removable wheel support, said bases resting on the bottom of the cavity of the microwave oven and ensuring the immobility of the removable wheel support relative to said cavity.

Ces embases, montées sur le support de roues amovible, sont montées libres en rotation autour des axes desdites roues, le centre de gravité desdites embases étant positionné de telle sorte que la partie desdites embases laissant apparaítre les roues se trouve toujours sur le dessus, quelle que soit l'orientation du support de roues amovible.These bases, mounted on the removable wheel support, are mounted free in rotation about the axes of said wheels, the center of gravity of said bases being positioned so that the part of said bases revealing the wheels is located always on the top, regardless of the orientation of the support of removable wheels.

Ainsi, quel que soit le sens dans lequel le support de roues amovible est inséré dans la cavité du four à micro-ondes, il reposera toujours sur les embases et présentera les roues prêtes à recevoir le plateau tournant. L'invention élimine donc les dysfonctionnements liés à la présence de corps étrangers entre les roues et la virole.So, whatever the direction in which the wheel support removable is inserted into the cavity of the microwave oven, it will rest always on the bases and will present the wheels ready to receive the turntable. The invention thus eliminates the malfunctions related the presence of foreign bodies between the wheels and the shell.

En outre, une conséquence intéressante de l'invention est qu'elle élimine les dysfonctionnements liés à un mauvais positionnement du support de roues.In addition, an interesting consequence of the invention is that it eliminates malfunctions related to a bad positioning of the wheel support.

Une autre conséquence intéressante de ce dispositif est qu'il facilite le nettoyage de la cavité du four à micro-ondes puisque son retrait et sa mise en place sont faciles.Another interesting consequence of this device is that it facilitates the cleaning of the cavity of the microwave oven since its removal and setting it up are easy.

Dans un mode de réalisation préféré de l'invention, les embases viennent se positionner dans un embouti circulaire réalisé dans le fond de la cavité du four à micro-ondes.
   Idéalement, le diamètre de l'embouti circulaire réalisé dans le fond de la cavité du four à micro-ondes est identique à celui de la bande de roulement circulaire spécifique présente sur les plateaux tournants standard et sur laquelle viennent rouler les roues 5.In a preferred embodiment of the invention, the bases are positioned in a circular stamp formed in the bottom of the cavity of the microwave oven.
Ideally, the diameter of the circular stamping made in the bottom of the cavity of the microwave oven is identical to that of the specific circular tread present on the standard rotating plates and on which roll the wheels 5.

Ainsi le mouvement de rotation du plateau tournant est optimisé.Thus the rotational movement of the turntable is optimized.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, donnée à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels :

Other features and advantages of the invention will emerge from the following description, given by way of non-limiting example, with reference to the accompanying drawings in which:
  • Figure 1 is a perspective view of a microwave oven according to the invention;

  • Figure 4 is a detailed view of a wheel of the device and the base associated therewith.

A la figure 1 on a représenté une vue en perspective d'un four à micro-ondes selon l'invention. Bien entendu, de nombreux composants tels que les moyens de chauffage ou de ventilation du four ou encore son éclairage ne sont pas représentés ni décrits ici car ils ne différent pas des dispositifs bien connus de l'homme de l'art et présents sur les fours actuels.In Figure 1 there is shown a perspective view of an oven with microwave according to the invention. Of course, many components such as the heating or ventilation means of the oven or its lighting are not represented or described here because they do not different from devices well known to those skilled in the art and present on current ovens.

A la figure 2 on a représenté une vue en perspective d'un four à micro-ondes selon l'invention. Cette vue permet de bien visualiser les différents composants qui interviendront dans la description qui va suivre. On a donc représenté le fond 3 de la cavité du four à micro-ondes 1 où est disposé un plateau tournant 2.
   Le dispositif d'entraínement comprend un moyen 7 fournissant un couple de rotation au plateau tournant qui dans sa partie intérieure ne diffère pas des dispositifs connus et dans sa partie supérieure vient en prise avec des ergots situés sous le plateau tournant 2 afin d'assurer son entraínement, de façon elle aussi connue.
   Il comprend aussi un support de roues amovible 4 comprenant les axes de rotation 4' des roues 5 sur lesquelles le plateau tournant 2 est posé. Lesdits axes de rotation 4' sont orientés radialement par rapport au plateau tournant 2.
   Le dispositif d'entraínement comprend enfin des embases 6 montées sur le support de roues amovible 4, lesdites embases 6 reposant sur le fond 3 de la cavité du four à micro-ondes et assurant l'immobilité du support de roues amovible 4 par rapport à ladite cavité.
   Ces embases 6, montées sur le support de roues amovible 4, sont montées libres en rotation autour des axes 4' desdites roues 5, le centre de gravité desdites embases 6 étant positionné de telle sorte que la partie desdites embases 6 laissant apparaítre les roues 5 se trouve toujours sur le dessus, quelle que soit l'orientation du support de roues amovible 4.In Figure 2 there is shown a perspective view of a microwave oven according to the invention. This view makes it possible to clearly visualize the various components that will intervene in the description that follows. The bottom 3 of the cavity of the microwave oven 1 is thus shown, in which a rotating plate 2 is arranged.
The drive device comprises a means 7 providing a rotational torque to the turntable which in its inner part does not differ from known devices and in its upper part engages with lugs located under the turntable 2 to ensure its training, so it also known.
It also comprises a removable wheel support 4 comprising the rotation axes 4 'of the wheels 5 on which the turntable 2 is placed. Said rotation axes 4 'are oriented radially with respect to the turntable 2.
The drive device finally comprises bases 6 mounted on the removable wheel support 4, said bases 6 resting on the bottom 3 of the cavity of the microwave oven and ensuring the immobility of the removable wheel support 4 with respect to said cavity.
These bases 6, mounted on the removable wheel support 4, are mounted free to rotate about the axes 4 'of said wheels 5, the center of gravity of said bases 6 being positioned so that the portion of said bases 6 letting appear the wheels 5 is always on the top, regardless of the orientation of the removable wheel support 4.

A la figure 3 on a représenté une vue en coupe du dispositif d'entraínement du plateau tournant 2 selon l'invention. Cette vue reprend les éléments présentés dans la vue en perspective de la figure 1. On remarque que selon une caractéristique préférée de l'invention, les embases 6 viennent se loger dans un embouti circulaire réalisé dans le fond 3 de la cavité du four à micro-ondes 1. Cet embouti n'est pas indispensable mais facilite le positionnement du support de roues amovible 4. En effet, les embases 6 venant se centrer naturellement dans cet embouti, le positionnement du support de roues amovible 4 est assuré.In Figure 3 there is shown a sectional view of the device driving the turntable 2 according to the invention. This view the elements presented in the perspective view of the Figure 1. It is noted that according to a preferred characteristic of the invention, the bases 6 are housed in a stamped circular formed in the bottom 3 of the cavity of the microwave oven 1. This stamping is not essential but facilitates the positioning of the removable wheel support 4. Indeed, the bases 6 centering naturally on this stamping, the positioning of the removable wheel support 4 is provided.

Enfin, à la figure 4 on a représenté une vue de détail d'une roue 5 du dispositif et de l'embase 6 qui lui est associée. On distingue de plus une partie du support de roues amovible 4 et un axe 4' de roue 5 autour duquel est monté libre en rotation une embase 6.Finally, in Figure 4 there is shown a detail view of a wheel 5 of the device and the base 6 which is associated with it. We further distinguishes a part of the removable wheel support 4 and a axis 4 'of wheel 5 around which is mounted free in rotation a base 6.

Selon une caractéristique préférée de l'invention, le support de roues amovible 4 est métallique et en forme de cercle sur lequel sont rapportés, par soudure par exemple, les axes 4'. Mais toute autre forme pourrait être envisagée telle qu'une étoile comportant autant de branches que de roues 5.According to a preferred characteristic of the invention, the support of removable wheels 4 is metal and circle-shaped on which are reported by welding, for example, the axes 4 '. But any other shape could be envisaged such as a star with as many branches only wheels 5.

En ce qui concerne les roues 5, elles doivent être au nombre de trois au minimum pour assurer un appui plan pour les plateau tournant 2. Il est envisageable d'en prévoir plus, mais cela présente au moins deux inconvénients : un coût plus élevé et des risques d'hyperstatisme. Idéalement, les roues 5 sont réalisées en Téflon afin de réduire les frottements et il est, de plus, possible de prévoir sur le plateau tournant 2 une bande de roulement (non représentée) qui se trouve sur la zone de contact entre les roues 5 et le plateau tournant 2. Les roues 5 sont montées sur une gorge de l'axe 4' dont le diamètre est plus faible que celui du reste de l'axe 4'. Elles sont ainsi immobilisée axialement, mais peuvent tourner librement.As regards the wheels 5, they must be in number at least three to ensure a plane support for the plateau 2. It is possible to envisage more, but this presents at least two disadvantages: higher cost and risks of indeterminacy. Ideally, the wheels 5 are made of Teflon so to reduce friction and it is, moreover, possible to predict on the turntable 2 a tread (not shown) which is found on the contact area between the wheels 5 and the plateau 2. The wheels 5 are mounted on a groove of the axis 4 'whose diameter is smaller than the rest of the axis 4 '. They are thus immobilized axially, but can rotate freely.

Enfin, les embases peuvent être de forme quelconque à condition de respecter le fait qu'elles soient montées libres en rotation autour des axes 4' des roues 5 et que leur centre de gravité soit positionné à l'opposé, par rapport à l'axe 4', de la partie des roues 5 qu'elles laissent apparaítre.
   Les embases 6 de l'exemple illustrant l'invention ont une forme s'inscrivant dans un parallélépipède. Finally, the bases may be of any shape provided that they are mounted free to rotate about the axes 4 'of the wheels 5 and that their center of gravity is positioned opposite to the axis 4 ', the part of the wheels 5 they let appear.
The bases 6 of the example illustrating the invention have a shape forming part of a parallelepiped.

Une des faces, dénommée supérieure dans les lignes qui suivent, de ce parallélépipède est laissée ouverte afin de laisser dépasser la roue 5 qui vient se loger à l'intérieur des embases 6.
   Deux parois internes, parallèles entre elles et à deux des faces latérales du parallélépipède et perpendiculaires à la face supérieure ouverte de ce dernier, entourent la roue. Elles sont munies chacune d'une encoche de largeur supérieure au diamètre de l'axe 4' dans laquelle est inséré ledit axe 4'. Ces parois permettent de positionner axialement l'embase 6 sur l'axe 4' par l'intermédiaire des roues 5.
   Les faces latérales parallèles aux deux parois internes sont, elles aussi, munies d'encoches. Ces encoches sont conçues de telle façon que l'axe 4' ne peut pas en ressortir une fois inséré et que le seul mouvement qui lui est alors laissé est la rotation autour de l'axe 4'.
   D'autre part, les angles entre les faces latérales, parallèles aux deux parois internes, et la face du dessous, opposée à la face ouverte, sont Lronqués. Cela permet à l'embase 6 de mieux s'adapter à la forme de l'embouti circulaire réalisé dans le fond 3 de la cavité du four à micro-ondes 1.
   Enfin, la quantité de matière présente au dessus de la zone de passage de l'axe 4' est limitée au minimum nécessaire afin de positionner le centre de gravité de l'embase 6 le plus bas possible, c'est-à-dire le plus loin possible de la face supérieure ouverte. Ainsi la position naturelle de l'embase sera toujours face ouverte vers le haut, c'est-à-dire en position de fonctionnement, sans que l'utilisateur n'ait à choisir une orientation particulière pour le support de roues amovible 4.One of the faces, denominated superior in the following lines, of this parallelepiped is left open in order to let the wheel 5 which is housed inside the bases 6 pass.
Two internal walls, parallel to each other and to two of the lateral faces of the parallelepiped and perpendicular to the open upper face of the latter, surround the wheel. They are each provided with a notch of width greater than the diameter of the axis 4 'in which is inserted said axis 4'. These walls make it possible to position the base 6 axially on the axis 4 'via the wheels 5.
The side faces parallel to the two inner walls are also provided with notches. These notches are designed so that the axis 4 'can not come out once inserted and that the only movement left to him is the rotation about the axis 4'.
On the other hand, the angles between the lateral faces, parallel to the two inner walls, and the bottom face, opposite to the open face, are Lronques. This allows the base 6 to better adapt to the shape of the circular stamping made in the bottom 3 of the cavity of the microwave oven 1.
Finally, the amount of material present above the zone of passage of the axis 4 'is limited to the minimum necessary to position the center of gravity of the base 6 as low as possible, that is to say the further away from the open top. Thus the natural position of the base will always face upwards, that is to say in the operating position, without the user having to choose a particular orientation for the removable wheel support 4.

L'invention répond au souci de réaliser un dispositif d'entraínement d'un plateau tournant de four à micro-ondes présentant avantages suivants : une réduction des problèmes d'à-coup et de patinage liés à la présence de corps étrangers entre les roues et la virole, une grande facilité de démontage et une facilité de mise en position grâce à sa réversibilité et à sa capacité d'auto-centrage.The invention responds to the desire to make a device drive of a microwave oven turntable presenting advantages: a reduction in problems of jerkiness and skating related to the presence of foreign bodies between the wheels and the ferrule, ease of disassembly and ease of position thanks to its reversibility and self-centering ability.
