Description

L'invention concerne un dispositif de commande d'au moins deux voyants lumineux d'indication d'état montés sur un appareil électrodomestique équipé d'un thermostat réglable à ouverture rapide par passage de point mort comprenant un support isolant recevant un bras du thermostat, une lame formant contact fixe, une lame mobile pourvue d'une languette souple sur laquelle appuie une cheville isolante commandée par une vis rotative permettant d'obtenir une température de consigne et une autre lame mobile fixée à la lame mobile et dont l'extrémité libre porte un contact susceptible de prendre appui sur la lame formant contact fixe, ainsi qu'une entretoise isolante solidaire du bilame et commandant les lames mobiles, la lame formant contact fixe, et les lames mobiles étant fixées au support isolant, reliées respectivement à des bornes électriques connectées à une prise d'alimentation électrique, et alimentant les deux voyants lumineux.The invention relates to a device for controlling at least two indicator lights for status indication mounted on a household appliance fitted with an adjustable thermostat with quick opening by shifting from neutral, comprising an insulating support receiving an arm of the thermostat, a blade forming a fixed contact, a movable blade provided with a flexible tongue on which an insulating pin presses, controlled by a rotary screw making it possible to obtain a set temperature, and another movable blade fixed to the movable blade and the free end of which carries a contact capable of bearing on the blade forming a fixed contact, as well as an insulating spacer integral with the bimetallic strip and controlling the movable blades, the blade forming a fixed contact, and the movable blades being fixed to the insulating support, connected respectively to terminals connected to an electrical supply outlet, and supplying the two indicator lights.

Dans les appareils électrodomestiques tels que, par exemple, les fers à repasser, l'usage de voyants lumineux d'indication d'état de la température de la semelle est très fréquent. Les dispositifs de commande de ces voyants lumineux d'indication d'état sont généralement complexes, encombrants et coûteux.In household electrical appliances such as, for example, irons, the use of indicator lights to indicate the status of the soleplate temperature is very frequent. The control devices for these status indication lights are generally complex, bulky and expensive.

D'autre part, ces dispositifs de commande font appel à des dispositifs électroniques de traitement des informations issues d'un thermostat à ouverture rapide et commandant le déclenchement des voyants lumineux. Les dispositifs électroniques sont sensibles aux variations de température et à l'humidité. De plus, l'insertion de tels dispositifs électroniques augmentent considérablement le prix de revient d'un appareil électrodomestique.On the other hand, these control devices use electronic devices for processing information from a quick-opening thermostat and controlling the triggering of the indicator lights. Electronic devices are sensitive to variations in temperature and humidity. In addition, the insertion of such electronic devices considerably increases the cost price of a household electrical appliance.

Le but de l'invention est de remédier aux inconvénients précités en mettant en oeuvre un dispositif de commande des voyants lumineux qui soit mécanique, simple et économique.The object of the invention is to remedy the aforementioned drawbacks by implementing a device for controlling the indicator lights which is mechanical, simple and economical.

Selon l'invention, le dispositif de commande d'au moins deux voyants lumineux d'indication d'état montés sur un appareil électrodomestique comporte une lame conductrice élastique comportant une extrémité libre et une extrémité fixée au support isolant, reliée électriquement par cette extrémité à la borne et en prise avec la languette souple par un moyen d'appui, et un élément conducteur fixé sur l'entretoise isolante, relié par une liaison électrique à un des deux voyants lumineux et susceptible de venir au contact de l'extrémité libre lorsque la température de chauffe est supérieure à la température de consigne.According to the invention, the device for controlling at least two indicator lights for indicating the state mounted on a household appliance comprises an elastic conductive strip comprising a free end and one end fixed to the insulating support, electrically connected by this end to the terminal and in engagement with the flexible tongue by a support means, and a conductive element fixed on the insulating spacer, connected by an electrical connection to one of the two indicator lights and capable of coming into contact with the free end when the heating temperature is higher than the set temperature.

Grâce au dispositif de commande selon l'invention, on élimine les dispositifs électroniques et on obtient ainsi une limitation du nombre de composants électriques à l'intérieur de l'appareil électrodomestique qui diminue le coût dudit appareil. D'autre part, la simplicité dudit dispositif augmente l'espace libre à l'intérieur de l'appareil électrodomestique améliorant les possibilités d'agencement des nombreux éléments contenus à l'intérieur de l'appareil électrodomestique.Thanks to the control device according to the invention, the electronic devices are eliminated and a limitation is therefore obtained on the number of electrical components inside the household appliance which reduces the cost of said appliance. On the other hand, the simplicity of said device increases the free space inside the household appliance improving the possibilities of arrangement of the numerous elements contained inside the household appliance.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre d'un mode de réalisation pris à titre d'exemple non limitatif illustré au dessin annexé représentant de manière schématique un appareil électrodomestique et le dispositif de commande des voyants lumineux selon l'invention associé à un thermostat représenté à une échelle différente.The characteristics and advantages of the invention will become apparent from the following description of an embodiment taken by way of nonlimiting example illustrated in attached drawing schematically showing a household appliance and the control device of the indicator lights according to the invention associated with a thermostat shown on a different scale.

Selon la figure, un thermostat de type réglable 1 muni d'un dispositif à ouverture rapide 2 de type connu équipe un appareil électrodomestique, par exemple un fer à repasser F dont une partie correspondant seulement à la semelle chauffante est représentée. Un circuit d'alimentation d'une résistance électrique R chauffant la semelle du fer à repasser comprend des lignes électriques 3 et 4 reliées à une prise 5 destinée à être branchée sur un réseau de distribution électrique. Ledit circuit d'alimentation fonctionne avec le dispositif à ouverture rapide 2 qui est déplacé grâce à la flexion d'un bilame 6 apte à transmettre un déplacement à deux lames mobiles 7 et 8 par l'intermédiaire d'une cheville isolante 9 interposée entre une extrémité du bilame 6 et les extrémités de chacune des lames mobiles 7 et 8. La lame mobile 7 est fixée par l'une de ses extrémités au contact d'une borne électrique 19 et dont l'autre extrémité est fixée à la lame mobile 8 dont l'extrémité libre porte un contact susceptible de prendre appui sur une lame 16 formant contact fixe. La lame mobile 7 est pourvue d'une languette souple 20 réalisée, par exemple, par découpe sur ladite lame 7 et sur laquelle appuie une cheville isolante 22 commandée par une vis rotative 10 permettant d'obtenir une température de consigne.According to the figure, an adjustable type thermostat 1 provided with a quick-opening device 2 of known type equips a household appliance, for example an iron F, a part of which corresponding only to the heating soleplate is shown. A circuit for supplying an electrical resistance R heating the soleplate of the iron comprises electrical lines 3 and 4 connected to a socket 5 intended to be connected to an electrical distribution network. Said supply circuit operates with the quick-opening device 2 which is displaced by the bending of a bimetallic strip 6 capable of transmitting a displacement to two mobile blades 7 and 8 by means of an insulating pin 9 interposed between a end of the bimetallic strip 6 and the ends of each of the mobile blades 7 and 8. The mobile blade 7 is fixed by one of its ends in contact with an electrical terminal 19 and the other end of which is fixed to the mobile blade 8 the free end of which carries a contact capable of bearing on a blade 16 forming a fixed contact. The movable blade 7 is provided with a flexible tongue 20 produced, for example, by cutting on said blade 7 and on which an insulating peg 22 presses, controlled by a rotary screw 10 making it possible to obtain a set temperature.

Le thermostat 1 comprend également un support isolant constitué de trois éléments 13, 14 et 15 recevant un bras de thermostat 11 fixé par une vis 12 et la lame 16 formant contact fixe. Le support isolant par ses éléments 13, 14 et 15 maintient des bornes électriques 18 et 19 reliées respectivement aux lignes électriques 3 et 4.The thermostat 1 also includes an insulating support consisting of three elements 13, 14 and 15 receiving a thermostat arm 11 fixed by a screw 12 and the blade 16 forming a fixed contact. The insulating support by its elements 13, 14 and 15 maintains electrical terminals 18 and 19 connected respectively to the electrical lines 3 and 4.

La lame 16 formant contact fixe comporte une extrémité 25 plaquée contre une extrémité 26 de la borne 18, les extrémités 25 et 26 étant positionnées entre les éléments 14 et 15 du support isolant. L'autre extrémité 27 de la borne 18 est reliée par une liaison électrique 28 à une première patte 29 d'un voyant 30 et à une extrémité 31 de la résistance R, l'autre extrémité 32 de la résistance R étant reliée à la ligne électrique 3 de la prise 5. La deuxième patte 33 du voyant 30 est reliée à une borne 34 d'une résistance 35, l'autre borne 36 de la résistance 35 étant connectée à la ligne électrique 3. Une borne 37 d'une autre résistance 38 est reliée également à la ligne électrique 3. L'autre borne 39 de la résistance 38 est connectée à une patte 40 d'un autre voyant 41, l'autre patte 42 du voyant 41 étant reliée à une borne 43. Ladite borne 43 est fixée par un élément conducteur 44, par exemple un rivet, sur un bossage 45 de la cheville isolante 9. Le bossage 45 est en liaison avec la partie centrale de la cheville isolante 9 dont chacune des extrémités est reliée respectivement au bilame 6 et aux lames mobiles 7 et 8. Le rivet 44 présente, par exemple, une extrémité tronconique 46 en regard de laquelle est positionnée, à une distance déterminée, une extrémité 47 d'une lame conductrice élastique 48. L'autre extrémité 49 de ladite lame 48 est plaquée contre la borne 19, de manière que la borne 19, l'extrémité de la lame mobile 7 et l'extrémité de la lame 48 soient positionnées entre les éléments 14 et 13 du support isolant. La lame conductrice élastique 48 est, par exemple, une lame métallique comportant un trou 50 au travers duquel passe la cheville isolante 22. Ladite lame métallique 48 repose sur la languette souple 20 par un moyen d'appui 51. Ledit moyen d'appui est, par exemple, un ergot 51 réalisé par une découpe dans ladite lame 48. La lame conductrice 48 a, par exemple, un coefficient de raideur inférieur à la languette souple 20.
On comprendra mieux le fonctionnement du dispositif de commande des voyants lumineux grâce à l'explication qui va suivre.
On positionne la vis rotative 10 du thermostat 2 pour obtenir une température de consigne désirée. Dans notre exemple d'application sur un fer à repasser, cette température de consigne correspond au repassage d'un type de vêtement particulier. Lors du branchement de la prise 5 sur le réseau de distribution électrique, la semelle du fer à repasser chauffe, le voyant lumineux 30, par exemple d'une couleur verte, s'allume puisque le contact entre l'extrémité de la lame 16 formant contact fixe et l'extrémité libre de la lame mobile 8 est fermé. Puis, lors de la montée en température désirée, l'extrémité libre du bilame 6 se courbe vers le haut et tend à soulever l'extrémité des lames mobiles 7 et 8. Lorsqu'il y a dépassement du point mort : la lame mobile 8 quitte brutalement la lame formant contact fixe 16 pour venir buter contre un point fixe 23 de la lame mobile 7 et le voyant lumineux 30, par exemple désigné comme un voyant de chauffe, s'éteint ; la languette souple 20 de la lame mobile 7 pousse sur l'ergot 51 de la lame métallique 48 et écarte ladite lame 48 de l'extrémité 46 du rivet 44. Lorsque l'utilisateur désire une température inférieure à la température demandée précédemment, l'utilisateur tourne en sens inverse la vis rotative 10 du thermostat 2 de sorte que le contact entre l'extrémité de la lame 16 et l'extrémité libre de la lame mobile 8 vienne à s'ouvrir. La cheville isolante 22 appuie donc sur la languette souple 20 et l'enfonce, l'ergot 51 se trouve ainsi relâché. De ce fait, l'extrémité 47 de la lame métallique 48 vient au contact de l'extrémité 46 du rivet 44. Ce contact déclenche l'allumage du voyant lumineux 41, par exemple de couleur rouge, qui indique l'état trop chaud de la semelle du fer à repasser. Ce voyant ne s'éteint que lorsque la semelle du fer à repasser s'est refroidie, c'est-à-dire lorsque l'extrémité libre du bilame 6 a descendu légèrement et occupe une position correspondant à la nouvelle température désirée.The blade 16 forming a fixed contact has one end 25 pressed against one end 26 of the terminal 18, the ends 25 and 26 being positioned between the elements 14 and 15 of the insulating support. The other end 27 of the terminal 18 is connected by an electrical connection 28 to a first tab 29 of an indicator 30 and to one end 31 of the resistor R, the other end 32 of the resistor R being connected to the line electrical 3 of the socket 5. The second tab 33 of the indicator light 30 is connected to a terminal 34 of a resistor 35, the other terminal 36 of the resistor 35 being connected to the electrical line 3. A terminal 37 of another resistor 38 is also connected to the power line 3. The other terminal 39 of the resistor 38 is connected to a lug 40 of another indicator light 41, the other lug 42 of the indicator light 41 being connected to a terminal 43. Said terminal 43 is fixed by a conductive element 44, for example a rivet, to a boss 45 of the insulating plug 9. The boss 45 is in connection with the central part of the insulating plug 9, each of the ends of which is connected respectively to the bimetallic strip 6 and with movable blades 7 and 8. The rivet 44 presents te, for example, a frustoconical end 46 opposite which is positioned, at a determined distance, one end 47 of an elastic conductive strip 48. The other end 49 of said strip 48 is pressed against the terminal 19, so that the terminal 19, the end of the movable blade 7 and the end of the blade 48 are positioned between the elements 14 and 13 of the insulating support. The elastic conductive strip 48 is, for example, a metal strip having a hole 50 through which passes the insulating plug 22. Said metal strip 48 rests on the flexible tongue 20 by a support means 51. Said support means is , for example, a lug 51 produced by a cut in said blade 48. The conductive blade 48 has, for example, a coefficient of stiffness less than the flexible tongue 20.
The operation of the indicator light control device will be better understood by the following explanation.
The rotary screw 10 of thermostat 2 is positioned to obtain a desired set temperature. In our example of application on an iron, this set temperature corresponds to the ironing of a particular type of garment. When the plug 5 is connected to the electrical distribution network, the soleplate of the iron heats up, the indicator light 30, for example of a green color, lights up since the contact between the end of the blade 16 forming fixed contact and the free end of the movable blade 8 is closed. Then, during the desired rise in temperature, the free end of the bimetallic strip 6 bends upwards and tends to raise the end of the movable blades 7 and 8. When the neutral point is exceeded: the movable blade 8 suddenly leaves the blade forming a fixed contact 16 to abut against a fixed point 23 of the movable blade 7 and the indicator light 30, for example designated as a heating indicator, goes out; the flexible tongue 20 of the movable blade 7 pushes on the lug 51 of the metal blade 48 and separates said blade 48 from the end 46 of the rivet 44. When the user desires a temperature lower than the temperature previously requested, the user rotates the rotary screw 10 of the thermostat 2 in the opposite direction so that the contact between the end of the blade 16 and the free end of the movable blade 8 comes to open. The insulating plug 22 therefore presses on the flexible tongue 20 and pushes it in, the lug 51 is thus released. Therefore, the end 47 of the metal blade 48 comes into contact with the end 46 of the rivet 44. This contact triggers the lighting of the indicator light 41, for example of red color, which indicates the too hot state of the soleplate of the iron. This indicator does not go out until the soleplate of the iron has cooled, that is to say when the free end of the bimetallic strip 6 has dropped slightly and occupies a position corresponding to the new desired temperature.

Le dispositif de commande de voyants lumineux selon l'invention s'applique sur un fer à repasser, mais peut être utilisé sur tout type d'appareils tels que fours, gaufriers, friteuses dans lesquelles l'indication d'une température trop élevée doit être connue de l'utilisateur.The indicator light control device according to the invention is applied to an iron, but can be used on any type of appliance such as ovens, waffle irons, fryers in which the indication of a temperature which is too high must be known to the user.
