The program control switch comprises a small electric motor, fed with alternating current for the high-speed drive of a program-selection cam-disc unit, and a bridge rectifier which is in series between the electric motor and the change-over relay which is a direct-current change-over relay.

Description

La présente invention concerne les dispositifs permettant de couper au moyen d'un relais contacteur l'alimentation puissance d'une machine à laver pendant la phase de sélection automatique d'un programme, réalisée a l'aide d'un moteur d'avance rapide.The present invention relates to devices making it possible to cut by means of a contactor relay the power supply to a washing machine during the automatic selection phase of a program, carried out using a fast forward motor. .

Les machines à laver automatiques permettent de réaliser différents programmes de lavage que ce soit suivant la qualité du lingepour les machines à laver le linge ou suivant l'état d'encrassement des objets ménagers pour les machines à laver la vaisselle. Dans les machines pour lesquelles la sélection du programme est réalisée au moyen d'un clavier à touches, un petit moteur électrique auxiliaire fait tourner rapidement le bloc de cames programme suivant un angle plus ou moins important pendant que la machine est sous tension.Automatic washing machines allow you to carry out different washing programs, depending on the quality of the laundry for washing machines or on the state of soiling of household objects for dishwashers. In machines for which program selection is carried out using a keypad, a small auxiliary electric motor quickly turns the block of program cams at a greater or lesser angle while the machine is on.

Il en résulte alors des commutations brèves et intempestives des diverses charges électriques telles que électrovannes,
ou moteur de pompe et moteur d'essorage/lavage. Ces commutations pressentent les inconvénients d'émettre des parasites radioélectriques, d'user prématurément les contacts et dans certains cas de commander une fonction non souhaitée telle que par exemple l'introduction irréversible d'agents de lavage.This then results in brief and untimely switching of the various electrical charges such as solenoid valves,
or pump motor and spin / wash motor. These switches sense the drawbacks of emitting radio interference, of prematurely wearing out the contacts and in certain cases of controlling an undesired function such as for example the irreversible introduction of washing agents.

Pour résoudre ces problèmes, il est nécessaire de couper l'alimentation électrique sur les circuits dits de puissance pendant la rotation rapide du bloc cames. Cette coupure doit s'opérer automatiquement et, comme la rotation rapide du bloc cames est assurée'pas un petit moteur électrique spécifique, il est courant de monter en parallèle aux bornes de ce moteur un relais de commutation. Ce relais doit donc être prévu pour la même tension d'alimentation que celle du moteur. Cette tension étant de 220 Volts alternatif dans le domaine de l'électroménager, le relais a nécessairement un bobinage réalisé en fil très fin ce qui le rend onéreux.To solve these problems, it is necessary to cut off the power supply to the so-called power circuits during the rapid rotation of the cam block. This cut-off must take place automatically and, as the rapid rotation of the cam block is ensured, not a small specific electric motor, it is common to mount a switching relay in parallel at the terminals of this motor. This relay must therefore be provided for the same supply voltage as that of the motor. This voltage being 220 Volts AC in the field of household appliances, the relay necessarily has a winding made of very fine wire which makes it expensive.

Le dispositif, objet de l'invention, permet d'éviter cet inconvénient. Dans celui-ci en effet, le relais utilisé est un relais courant continu, alimenté par un pont redresseur monté en série avec le moteur d'avance rapide.The device which is the subject of the invention makes it possible to avoid this drawback. In this one, in fact, the relay used is a direct current relay, supplied by a rectifier bridge mounted in series with the rapid advance motor.

L'utilisation directe d'un relais en basse tension alternative, monté en série avec le moteur d'avance rapide, conduirait également à un relais plus onéreux et plus encombrant qu'un relais basse tension courant continu, malgré l'obligation d'ajouter un pont redresseur par exemple du type à quatre diodes d'usage courant.The direct use of a relay in low AC voltage, mounted in series with the fast forward motor, would also lead to a more expensive and more bulky relay than a low voltage DC relay, despite the obligation to add a rectifier bridge for example of the type with four diodes in common use.

Le dessin annexé illustre, à titre d'exemple, un mode de réalisation du dispositif, conforme à la présente invention.The appended drawing illustrates, by way of example, an embodiment of the device, in accordance with the present invention.

Dans un programmateur de machine à laver, dont l'énergie mécanique est fournie par deux petits moteurs synchrones à savoir, un moteur 1 ayant pour rle de faire avancer le bloccames en pas à pas et un moteur 4 permettant une avance rapide et continue du même bloc cames, les cames agissent de façon connue sur des contacts à lames C1, C2 etc... selon le programme de lavage de la machine à piloter.In a washing machine programmer, whose mechanical energy is supplied by two small synchronous motors, namely, a motor 1 having the role of advancing the blocks in step and a motor 4 allowing a rapid and continuous advance of the same cam block, the cams act in a known manner on blade contacts C1, C2 etc ... according to the washing program of the machine to be controlled.

Ces divers contacts ont pour rôle de distribuer l'alimentation électrique, par exemple sous 220 V. alternatif entre les lignes
L1 et L2, aux organes de la machine tels que, une ou plusieurs électrovannes 2, des résistances de chauffage 3 et des moteurs 10 de pompe et/ou d'entrainement de moyens de lavage.These various contacts have the role of distributing the electrical supply, for example under 220 V. alternating between the lines
L1 and L2, to the components of the machine such as, one or more solenoid valves 2, heating resistors 3 and motors 10 for pump and / or washing means drive.

Le choix d'un programme de lavage, qui correspond à une position angulaire déterminée du bloc cames, prise comme origine du cycle, est obtenu par la fermeture manuelle de l'un des interrupteurs bistables 7, 8 ou 9, dont la continuité électrique est respectivement assurée, vers le moteur d'avance rapide 4, au travers des contacts de cames C7, C8 ou C Chacun de ces contacts s'ouvre lorsque le bloc cames a atteint la bonne position angulaire, correspondant au programme choisi.The choice of a washing program, which corresponds to a determined angular position of the cam block, taken as the origin of the cycle, is obtained by manual closing of one of the bistable switches 7, 8 or 9, whose electrical continuity is respectively provided, to the fast forward motor 4, through the cam contacts C7, C8 or C Each of these contacts opens when the cam block has reached the correct angular position, corresponding to the chosen program.

Les autres organes de la machine 1, 2, 3 et 10 peuvent être également électriquement isolés par le contacteur 61 du relais 6.The other components of the machine 1, 2, 3 and 10 can also be electrically isolated by the contactor 61 of the relay 6.

Le contacteur 61 est prévu pour 16 Ampères 250 Volts et le relais 61 est un relais courant continu équipé d'une bobine 24 Volts de 300 milliwatts. L'alimentation de ce relais est assurée par un pont redresseur 5, à quatre diodes, monté en série avec le moteur d'avance rapide 4. Ce moteur d'avance rapide est un petit moteur synchrone bobiné en 195 Volts, d'une puissance de l'ordre de 3 watts.The contactor 61 is provided for 16 amps 250 volts and the relay 61 is a direct current relay equipped with a 24 volt coil of 300 milliwatts. The supply of this relay is ensured by a rectifier bridge 5, with four diodes, connected in series with the fast advance motor 4. This fast advance motor is a small synchronous motor wound in 195 Volts, of a power of the order of 3 watts.

Le fonctionnement du dispositif est le suivant.The operation of the device is as follows.

Le contact général 11 étant fermé, la fermeture de l'un des interrupteurs C7, C8 ou Cg met sous tension le moteur d'avance rapide et le pont redresseur 5. Il en résulte que, simultanémen le relais 6 est alimenté ce qui, par son interrupteur 61, met hors circuit les organes dits de puissance de la machine.The general contact 11 being closed, the closing of one of the switches C7, C8 or Cg energizes the fast forward motor and the rectifier bridge 5. It follows that, simultaneously, the relay 6 is supplied which, by its switch 61 switches off the so-called power components of the machine.

L'ouverture du contact du bloc cames, par exemple C7 pour le contact 7, correspondant au programme sélectionné provoque l'arrêt du moteur d'avance rapide , la mise hors tension du relais 6 et la fermeture de son interrupteur 61. Ceci à pour conséquence d'alimenter à son tour le petit moteur synchrone 1 d'avance pas à pas et de permettre la mise sous tension au cour. The opening of the contact of the cam block, for example C7 for contact 7, corresponding to the selected program causes the fast advance motor to stop, the relay 6 to be switched off and its switch 61 to close. consequence in turn of feeding the small synchronous motor 1 in advance step by step and allowing the power to be turned on.

du cycle des autres organes de la machine, reliés de façon connue aux divers contacts du bloc-cames.of the cycle of the other parts of the machine, connected in a known manner to the various contacts of the cam block.

Le dispositif objet de l'invention se prête particulièrement bien à la réalisation de programmateurs à sélection automatique du programme de lavage. The device which is the subject of the invention lends itself particularly well to the production of programmers with automatic selection of the washing program.
