Description

La présente invention concerne les fours à micro-ondes et plus particulièrement les dispositifs de sécurité utilisés dans les fours à micro-ondes. Généralement, un four à micro-ondes comporte une cavité de cuisson équipée d'une porte mobile articulée sur la face avant dudit four et destinée à venir fermer complètement l'orifice de la cavité en se rabattant sur la face avant. Ladite porte mobile est maintenue fermée au moins par un crochet qui pénètre dans une ouverture située sur ladite face avant et qui comporte un nez d'actionnement d'un élément de verrouillage ainsi qu'un cran situé derrière le nez et dans lequel l'élément de verrouillage s'engage. Ledit élément de verrouillage ainsi positionné autorise la fermeture ultérieure d'un interrupteur de mise en fonctionnement dudit four sous l'action d'une touche de fonctionnement située sur un tableau de bord agencé sur la face avant du four.The present invention relates to microwave ovens and more particularly to the safety devices used in microwave ovens. Generally, a microwave oven has a cooking cavity equipped with a movable door hinged on the front face of said oven and intended to completely close the orifice of the cavity by folding down on the front face. Said movable door is kept closed at least by a hook which enters an opening located on said front face and which comprises an actuating nose of a locking element as well as a notch located behind the nose and in which the element lock engages. Said locking element thus positioned authorizes the subsequent closing of a switch for operating said oven under the action of an operating button located on a dashboard arranged on the front face of the oven.

Les ouvertures par lesquelles pénètre le crochet étant suffisamment visibles lorsque la porte du four à micro-ondes est ouverte, il est possible, pour un enfant, d'introduire dans cette ouverture un élément plat, par exemple, le manche d'une cuillère, en vue d'actionner l'élément de verrouillage.The openings through which the hook enters being sufficiently visible when the door of the microwave oven is open, it is possible for a child to introduce into this opening a flat element, for example, the handle of a spoon, to activate the locking element.

Dans cette position, le four n'attend plus que la pression d'une touche de fonctionnement pour être mis en marche. Ce système de sécurité n'est donc pas suffisamment fiable et peut être dangereux pour des enfants.In this position, the oven only waits for the press of an operating button to start. This security system is therefore not sufficiently reliable and can be dangerous for children.

Le but de l'invention est de rémédier à cet inconvénient en mettant en oeuvre un dispositif permettant d'éviter tout fonctionnement lorsque la porte du four à micro-ondes est ouverte.The object of the invention is to remedy this drawback by implementing a device making it possible to avoid any operation when the door of the microwave oven is open.

Selon l'invention le dispositif est caractérisé en ce que l'élément de verrouillage est constitué d'une roue qui est positionnée sur une platine fixée transversalement à la face avant interne du four à micro-ondes et gui est fixée à ladite platine par un arbre parallèle à ladite face avant et autour duquel la roue peut effectuer un mouvement de rotation, ladite roue comportant une première face comprenant deux plots de butée, un premier plot de butée situé sur le chemin du nez et un second plot de butée angulairement décalé et destiné après rotation de ladite roue par action du nez sur le premier plot, à venir s'engager dans le cran du crochet ainsi qu'un verrou de sécurité comprenant un doigt de blocage qui est destiné à venir en butée sur un bossage d'arrêt solidaire de la platine et disposé en regard de la seconde face de la roue, et qui est monté mobile à cet effet à l'encontre d'un moyen élastique sur ladite seconde face de la roue, ledit doigt de blocage étant commandé par un ergot de sécurité qui fait saillie à travers une lumière transversalement à la première face de la roue, et qui est agencé entre les deux plots de butée de manière à occuper deux positions, soit une position de mise en attente de démarrage pour laquelle il est actionné par le nez du crochet et en laquelle il escamote le doigt de blocage permettant ainsi une rotation déterminée de la roue de manière à autoriser la fermeture ultérieure de l'interrupteur de fonctionnement, soit une position active pour laquelle, en l'absence d'une action du nez, il vient buter sur le bossage d'arrêt et entrave la rotation de ladite roue interdisant ainsi l'autorisation de fermeture de l'interrupteur.According to the invention the device is characterized in that the locking element consists of a wheel which is positioned on a plate fixed transversely to the internal front face of the microwave oven and which is fixed to said plate by a shaft parallel to said front face and around which the wheel can rotate, said wheel comprising a first face comprising two stop studs, a first stop stud located in the path of the nose and a second angularly offset stop stud and intended after rotation of said wheel by action of the nose on the first stud, to come to engage in the notch of the hook as well as a safety lock comprising a locking finger which is intended to come into abutment on a stop boss integral with the plate and arranged opposite the second face of the wheel, and which is mounted movable for this purpose against an elastic means on said second face of the wheel, said finger locking being controlled by a safety lug which protrudes through a light transverse to the first face of the wheel, and which is arranged between the two abutment pads so as to occupy two positions, namely a position in standby for start-up for which it is actuated by the nose of the hook and in which it retracts the locking finger thus allowing a determined rotation of the wheel so as to allow the subsequent closing of the operating switch, ie an active position for which, in l absence of an action of the nose, it comes up against the boss stopping and hindering the rotation of said wheel thus preventing authorization to close the switch.

Grâce à ce dispositif selon l'invention, on utilise un système simple à mettre en oeuvre et on augmente considérablement la sécurité d'un four à micro-ondes en empêchant tout utilisateur de déclencher le fonctionnement de l'appareil lorsque la porte dudit four est ouverte. D'autre part, le dispositif monté parallèle aux ouvertures par lesquelles pénètre le crochet de verrouillage, permet de libérer un espace important derrière le tableau de bord du four à micro-ondes et de limiter ainsi l'encombrement.Thanks to this device according to the invention, a simple system to be used is used and the safety of a microwave oven is considerably increased by preventing any user from triggering the operation of the appliance when the door of said oven is opened. On the other hand, the device mounted parallel to the openings through which the locking hook enters, makes it possible to free up a large space behind the dashboard of the microwave oven and thus to limit the bulk.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins annexés dans lesquels :

  • la Figure 1 représente en perspective le dispositif de mise en position de démarrage selon l'invention et agencé dans un four à micro-ondes représenté partiellement et équipée d'une porte mobile en position entrouverte ;

Selon la Figure 1, seulement une partie des éléments constituant un four à micro-ondes est représentée. Le four à micro-ondes comporte, une cavité de cuisson non représentée dont les parois latérales portent la référence 1. Une face avant 2 du four à micro-ondes forme une ouverture donnant accès à la cavité de cuisson. Une porte mobile 3 articulée sur la face avant 2 est destinée à venir fermer complètement la cavité de cuisson. Ladite porte mobile 3 comprend un système de fermeture, par exemple, au moins un crochet 4 fixé, par exemple, par fixation amovible sur la porte et permettant d'obtenir une fermeture complète de la porte ; ce crochet 4 comporte, par exemple, un nez d'actionnement 5 et un cran 6. Le cran 6 a, par exemple, une forme de U inversé, la partie courbe du U étant légèrement modifiée de manière à créer une légère pente s'élevant en direction du nez et facilitant le coulissement de l'élément de verrouillage 7 du four à micro-ondes. Le nez d'actionnement a, par exemple, une épaisseur e comme la totalité du crochet 4, une largeur 1 et un rétrécissement 8 suffisamment large pour éviter toute flexibilité dudit nez lors du contact du nez sur l'élément de verrouillage 8 du four à micro-ondes.According to Figure 1, only part of the elements constituting a microwave oven is shown. The microwave oven comprises a cooking cavity, not shown, the side walls of which bear the reference 1. A front face 2 of the microwave oven forms an opening giving access to the cooking cavity. A movable door 3 articulated on the front face 2 is intended to completely close the cooking cavity. Said movable door 3 comprises a closure system, for example, at least one hook 4 fixed, for example, by removable fixing on the door and making it possible to obtain complete closure of the door; this hook 4 comprises, for example, an actuating nose 5 and a notch 6. The notch 6 has, for example, an inverted U shape, the curved part of the U being slightly modified so as to create a slight slope s' elevating towards the nose and facilitating the sliding of the locking element 7 of the microwave oven. The actuating nose has, for example, a thickness e like the entire hook 4, a width 1 and a narrowing 8 sufficiently wide to avoid any flexibility of said nose during contact of the nose on the locking element 8 of the microwave.

La face avant 2 du four à micro-ondes comprend, outre une première ouverture 9 permettant au crochet 4 de la porte mobile 3 de pénétrer pour venir s'engager dans l'élément de verrouillage 7, d'autres ouvertures dont une seule 10 est représentée sur la Figure 1, lesdites ouvertures permettant, par exemple, par des pattes de fixation 11, 12 et 13, le positionnement d'une platine 14 supportant, en outre, l'élément de verrouillage et un interrupteur 15 de mise en fonctionnement du four à micro-ondes, ladite platine 14 est fixée transversalement à la face avant 2 du four à micro-ondes entre une des parois latérales 1 de la cavité de cuisson du four à micro-ondes et des emplacements 16, 17, 18 et 19 prévus pour l'encastrement d'un tableau de bord non représenté et contenant, par exemple, des composants déterminant des instructions de temps, de puissance, de cuisson rapide avec réglage de minuterie et de mise en marche de l'appareil.The front face 2 of the microwave oven comprises, in addition to a first opening 9 allowing the hook 4 of the movable door 3 to penetrate to come to engage in the locking element 7, other openings of which only one 10 is shown in Figure 1, said openings allowing, for example, by fixing lugs 11, 12 and 13, the positioning of a plate 14 supporting, in addition, the locking element and a switch 15 for operating the microwave oven, said plate 14 is fixed transversely to the front face 2 of the microwave oven between one of the side walls 1 of the cooking cavity of the microwave oven and locations 16, 17, 18 and 19 provided for mounting a dashboard not shown and containing, for example, components determining instructions for time, power, rapid cooking with timer setting and switching on the appliance.

L'élément de verrouillage 7 fixé sur la platine 14 est constitué, par exemple, d'une roue 20. La roue 20 est montée rotative sur ladite platine 14 autour d'un arbre 21 positionné parallèlement à la face avant 2 du four à micro-ondes et solidaire de la platine 14. Ladite roue 20 comporte, en outre, deux faces A et B placées en vis à vis dont une seule A est visible sur la Figure 1. La première face A comprend, par exemple, deux plots de butée 22 et 23, un premier plot de butée 22 situé sur le chemin du nez 5 du crochet 4 de la porte mobile 3 et un second plot 23, situé près du bord 22' de la première face A et décalé angulairement par rapport au premier plot 22 pour éviter toute butée du nez 5 sur le deuxième plot 23 lors de la fermeture de la porte mobile 3, ainsi qu'une lumière 23' agencée angulairement entre et sous les deux plots de butée 22 et 23 et permettant à un ergot de sécurité 24 positionné transversalement à la première face A de la roue 20 et constituant, en outre, un élément d'un doigt de blocage 25 (représenté sur les Figures 3a à 3c) et monté mobile sur la seconde face B de la roue 20 et en regard de la platine 14. Le doigt de blocage 25 est un élément d'un verrou de sécurité comprenant, en outre, un bossage d'arrêt 26 solidaire de la platine 14 et disposé en regard de la seconde face B de la roue 20. Le doigt de blocage 25 est monté mobile à l'encontre d'un moyen élastique constitué, par exemple, d'un système à ressort 27 (représenté sur les Figures 3a à 3c), fixé sur la seconde face B de la roue 20 et qui tend à amener l'extrémité libre 28 du doigt de blocage 25 à la périphérie de la roue 20 à proximité du bossage 26 de manière que, lorsqu'aucune action n'est exercée sur l'ergot de sécurité 24, la rotation de la roue 20 soit limitée à la distance existant entre l'extrémité libre 28 du doigt de blocage 25 et le bossage 26. Lesdits plots 22 et 23 sont, par exemple, ovoïdes. La première face A de la roue 20 comporte, également, un arbre 29 positionné sur la périphérie de la roue 20 et situé au sommet d'un triangle passant par les plots de butée 22 et 23. Un basculeur 30 est monté libre autour de cet arbre 29 de façon pendulaire. L'extrémité libre 31 de ce basculeur 30 a, par exemple, une forme arrondie.The locking element 7 fixed on the plate 14 consists, for example, of a wheel 20. The wheel 20 is rotatably mounted on said plate 14 around a shaft 21 positioned parallel to the front face 2 of the micro oven -waves and integral with the plate 14. Said wheel 20 further comprises two faces A and B placed opposite, of which only one A is visible in FIG. 1. The first face A comprises, for example, two studs of stop 22 and 23, a first stop stud 22 located on the path of the nose 5 of the hook 4 of the movable door 3 and a second stud 23, located near the edge 22 'of the first face A and offset angularly relative to the first pad 22 to avoid any abutment of the nose 5 on the second pad 23 when the movable door 3 is closed, as well as a light 23 'arranged angularly between and under the two stop pads 22 and 23 and allowing a lug to safety 24 positioned transversely to the first face A of the wheel 20 and constituting, in addition, an element of a locking finger 25 (shown in Figures 3a to 3c) and mounted movably on the second face B of the wheel 20 and facing the plate 14. The locking finger 25 is a element of a security lock further comprising a stop boss 26 integral with the plate 14 and disposed opposite the second face B of the wheel 20. The locking pin 25 is mounted movably against '' an elastic means consisting, for example, of a spring system 27 (shown in Figures 3a to 3c), fixed on the second face B of the wheel 20 and which tends to bring the free end 28 of the locking finger 25 at the periphery of the wheel 20 near the boss 26 so that, when no action is exerted on the safety lug 24, the rotation of the wheel 20 is limited to the distance existing between the free end 28 of the locking finger 25 and the boss 26. Said studs 22 and 23 are, for example, ovoid. The first face A of the wheel 20 also includes a shaft 29 positioned on the periphery of the wheel 20 and situated at the top of a triangle passing through the abutment pads 22 and 23. A rocker 30 is mounted free around this tree 29 of pendulum. The free end 31 of this rocker 30 has, for example, a rounded shape.

Selon la Figure 2, lorsque la porte du four est fermée, le deuxième plot 23 ainsi que l'ergot de sécurité 24 de la roue 20 sont placés à l'intérieur du cran 6 du crochet 4. La roue 20 possédant sur sa première face A l'arbre 29 sur lequel est monté mobile le basculeur 27, ledit basculeur 27 passe de la position représentée à la Figure 1 à la position représentée à la Figure 2. En effet, lors de la rotation de la roue 20, l'arbre 26, sur lequel est monté de façon pendulaire le basculeur 27, effectue un mouvement de rotation limité par un épaulement 32 du crochet 4 (représenté par des pointillés). L'épaulement 32 est destiné à venir en butée contre la face avant 2 du four lorsque la porte mobile 3 vient fermer complètement la cavité, une distance d entre ledit épaulement 32 et la face interne du cran 6 adjacente au nez 5 étant ainsi définie de manière rigoureuse par le constructeur pour obtenir la fermeture complète sans jeu de la porte 3.According to Figure 2, when the oven door is closed, the second stud 23 and the safety lug 24 of the wheel 20 are placed inside the notch 6 of the hook 4. The wheel 20 having on its first face At the shaft 29 on which the rocker 27 is movably mounted, said rocker 27 passes from the position shown in Figure 1 to the position shown in Figure 2. Indeed, during the rotation of the wheel 20, the shaft 26, on which the rocker 27 is pendulumly mounted, performs a rotational movement limited by a shoulder 32 of the hook 4 (represented by dotted lines). The shoulder 32 is intended to abut against the front face 2 of the oven when the movable door 3 comes to completely close the cavity, a distance d between said shoulder 32 and the internal face of the notch 6 adjacent to the nose 5 being thus defined by rigorously by the manufacturer to obtain complete closure of the door 3 without play.

Ce basculeur 30, par effet de gravité, a son extrémité 31 qui vient se positionner au niveau de l'interrupteur 15. Cet interrupteur 15 possédant un bouton poussoir 33 de déclenchement, il suffit d'un mouvement de pivotement du basculeur 30 pour activer l'interrupteur 15 de mise en fonctionnement du four à micro-ondes. Ce mouvement de pivotement du basculeur 30 est provoqué, par exemple, par un volet 34 monté mobile en rotation autour d'un axe d'articulation 35. La rotation de ce volet, suivant une flèche F4, est occasionnée, par exemple, par une touche de fonctionnement 36 qui est la touche de mise en marche du four à micro-ondes située sur le tableau de bord et représentée partiellement.This rocker 30, by gravity effect, has its end 31 which is positioned at the level of the switch 15. This switch 15 having a push button 33 for triggering, it suffices with a pivoting movement of the rocker 30 to activate the 'switch 15 for operating the microwave oven. This pivoting movement of the rocker 30 is caused, for example, by a flap 34 mounted movable in rotation about a hinge pin 35. The rotation of this flap, along an arrow F4 , is caused, for example, by a operating button 36 which is the start button for the microwave oven located on the dashboard and shown partially.

Selon la Figure 3a, lors de la fermeture de la porte mobile 3 sur lequel est fixée le crochet 4, le nez 5 dudit crochet 4 effectue un mouvement de rotation autour de l'axe d'articulation de la porte suivant une flèche F1. Le nez 5 s'engage dans l'ouverture 9 de la face avant 2 du four à micro-ondes et vient heurter le premier plot 22 de la roue 20. Avant le contact du nez 5 sur le premier plot 22, le doigt de blocage 25, montré détaché de la roue 20 pour une meilleure compréhension, est situé à proximité du bossage 26 pour venir en butée contre ce dernier si aucune action n'est exercée sur l'ergot de sécurité 24. La fermeture de la porte se poursuivant, comme montrée sur la Figure 3a, la force F1 exercée sur le premier plot 22 entraîne la roue 20 en rotation.According to FIG. 3a, when the movable door 3 is closed on which the hook 4 is fixed, the nose 5 of said hook 4 performs a rotational movement around the hinge axis of the door according to an arrow F1 . The nose 5 engages in the opening 9 of the front face 2 of the microwave oven and strikes the first stud 22 of the wheel 20. Before the nose 5 contacts the first stud 22, the locking finger 25, shown detached from the wheel 20 for a better understanding, is located near the boss 26 to abut against the latter if no action is exerted on the safety lug 24. The closing of the door continuing, as shown on Figure 3a, the force F1 exerted on the first pad 22 drives the wheel 20 in rotation.

D'autre part, selon la Figure 3b, le nez 5 du crochet exerce par sa partie inférieure, sur l'ergot de sécurité 24, une action dans la direction de la flèche F2. Le doigt de blocage 25 est monté mobile sur un axe 37 de la seconde face B de la roue 20, à l'encontre du ressort 27 comprenant deux extrémités 38 et 39, l'une 38 est liée au doigt de blocage 25, l'autre 39 est liée à la roue 20, cette liaison étant figurativement représentée sur les vues éclatées 3a, 3b, 3c.On the other hand, according to Figure 3b, the nose 5 of the hook exerts through its lower part, on the safety lug 24, an action in the direction of the arrow F2 . The locking finger 25 is mounted movably on an axis 37 of the second face B of the wheel 20, against the spring 27 comprising two ends 38 and 39, one 38 is linked to the locking finger 25, the another 39 is linked to the wheel 20, this connection being represented figuratively in the exploded views 3a, 3b, 3c.

Le basculement de l'ergot de sécurité 24 et la rotation de la roue 20 permettent au doigt de blocage 25 de pivoter et de s'escamoter, évitant ainsi le bossage 26 qui limitait le déplacement angulaire de la roue 20 lorsqu'aucune action n'est exercée sur l'ergot de sécurité 24.The tilting of the safety lug 24 and the rotation of the wheel 20 allow the locking finger 25 to pivot and retract, thus avoiding the boss 26 which limited the angular displacement of the wheel 20 when no action is exerted on the safety lug 24.

La position finale de la roue 20 après fermeture complète de la porte mobile 3 du four à micro-ondes est représentée à la Figure 2.The final position of the wheel 20 after complete closure of the movable door 3 of the microwave oven is shown in FIG. 2.

Selon la Figure 3c, le doigt 25 présente un trou 40, parallèle à l'ergot de sécurité 24 et qui permet l'enfilement sur l'arbre 37 de la seconde face B de la roue 20. La roue 20 a son arbre de fixation 21 monté rotatif dans un trou 42 réalisé dans la platine 14. Une rondelle de maintien (non représentée) fixée sur le bout de l'arbre 21 après son engagement dans le trou 42 sur l'autre face (non représentée) de la platine 14 permet le maintien axial de la roue 20 sur la platine 14 en laissant une libre rotation de ladite roue 20 autour de l'arbre 21.According to Figure 3c, the finger 25 has a hole 40, parallel to the safety pin 24 and which allows the threading on the shaft 37 of the second face B of the wheel 20. The wheel 20 has its fixing shaft 21 rotatably mounted in a hole 42 made in the plate 14. A retaining washer (not shown) fixed on the end of the shaft 21 after its engagement in the hole 42 on the other face (not shown) of the plate 14 allows the axial maintenance of the wheel 20 on the plate 14 leaving a free rotation of said wheel 20 around the shaft 21.

Ladite roue 20 est limitée dans son déplacement angulaire, par le crochet 4 de la porte mobile 3 du four à micro-ondes. En outre, pour tirer le crochet 4 vers l'intérieur du four, et donc appliquer la porte contre la face avant, la roue 20 et donc le premier plot 22 sont soumis à un dispositif d'entraînement en rotation comprenant un tenon 43 monté sur la seconde face B de la roue 20 et placé dans l'alignement de l'arbre 29 de la première face A de la roue 20, ledit tenon 43 traversant une glissière 44 réalisée sur la platine 14.Said wheel 20 is limited in its angular displacement, by the hook 4 of the movable door 3 of the microwave oven. In addition, to pull the hook 4 towards the interior of the oven, and therefore apply the door against the front face, the wheel 20 and therefore the first stud 22 are subjected to a rotary drive device comprising a tenon 43 mounted on the second face B of the wheel 20 and placed in alignment with the shaft 29 of the first face A of the wheel 20, said lug 43 passing through a slide 44 produced on the plate 14.

Pour commander ledit déplacement du tenon 43, l'extrémité 45 du tenon 43 dépassant, après montage de la roue 20 de la platine 14, est fixée à une première extrémité 46 d'une genouillère 47 à point médian instable sous l'effet d'un ressort 48 et représentée en pointillés car située sur l'autre face de la platine 14, tandis qu'une deuxième extrémité 49 passe à travers un support 50 fixe et solidaire de la platine 14 et sert de butée au ressort 48 ainsi que de palier de coulissement pour la genouillère 47.To control said movement of the tenon 43, the end 45 of the tenon 43 protruding, after assembly of the wheel 20 of the plate 14, is fixed to a first end 46 of a toggle joint 47 with unstable midpoint under the effect of a spring 48 and shown in dotted lines because located on the other face of the plate 14, while a second end 49 passes through a support 50 fixed and integral with the plate 14 and serves as a stop for the spring 48 as well as a bearing slide for the knee lifter 47.

C'est ainsi que le tenon 43 de la roue 20 passe d'une première position illustrée en 51 représentant l'axe du tenon 43 lorsqu'aucune action n'est exercée sur les plots 22 et 23 ainsi que sur l'ergot de sécurité 24, à une deuxième position illustrée en 52 représentant l'axe du tenon 43 après une action sur les éléments précités. Une flèche 53 représentée dans la glissière 44 décrit le mouvement de rotation effectué par le tenon 43 de la roue 20 lorsque le doigt de blocage 25 de la roue 20 est escamoté, évitant ainsi la mise en butée contre le bossage 26 et autorisant la poursuite du mouvement de rotation de la roue 20.Thus, the stud 43 of the wheel 20 passes from a first position illustrated at 51 representing the axis of the stud 43 when no action is exerted on the studs 22 and 23 as well as on the safety lug. 24, in a second position illustrated at 52 representing the axis of the post 43 after an action on the aforementioned elements. An arrow 53 shown in the slide 44 describes the rotational movement effected by the lug 43 of the wheel 20 when the locking pin 25 of the wheel 20 is retracted, thus avoiding the abutment against the boss 26 and allowing the continuation of the rotational movement of the wheel 20.

D'autres touches de fonctionnement peuvent déclencher la rotation du basculeur 30 pour déclencher l'interrupteur 15 de mise en fonctionnement dudit four, par exemple, une touche de dispositif de minutage préprogrammé d'un four à micro-ondes du type décrit, par exemple, dans la demande de brevet N° 2 630 613 ou une touche électronique d'un four à micro-ondes, mais dans ces derniers cas, il est indispensable d'adapter et de positionner des mécanismes adéquates non représentés pour faire fonctionner le dispositif. Le dispositif selon l'invention s'applique sur les fours à micro-ondes mais peut s'appliquer sur d'autres appareils nécessitant des sécurités très fiables.Other operating keys can trigger the rotation of the rocker 30 to trigger the switch 15 for operating said oven, for example, a preprogrammed timing device of a microwave oven of the type described, for example, in patent application No. 2,630,613 or an electronic button of a microwave oven, but in these latter cases it is essential to adapt and position adequate mechanisms not shown to operate the device. The device according to the invention is applicable to microwave ovens but can be applied to other devices requiring very reliable security.
