Description

La présente invention concerne un dispositif d'affichage, pour programmateur comportant un ensemble de cames-programmes, agencées pour être entraînées automatiquement en rotation et mettre en oeuvre plusieurs programmes établis successivement, et un élément sélecteur monté solidaire en rotation d'un axe de manoeuvre dont le positionnement angulaire permet de choisir l'un desdits programmes, comprenant :

  • - un organe de commande agencé pour commander un contact mobile en déplacement dans l'une ou l'autre de deux positions,
  • - l'organe étant agencé pour, sous l'action de l'élément sélecteur, coopérer avec des moyens de démarrage de l'ensemble de cames, être déplacé le long de l'axe de manoeuvre dans un sens, et déplacer ainsi le contact mobile d'une première position à la deuxième,
  • - l'organe comportant des moyens d'inversion du déplacement du contact mobile, de la deuxième position à la première, agencés pour, sous l'action de moyens de rappel, permettre le déplacement dans l'autre sens de l'organe, le long de l'axe de manoeuvre.
The present invention relates to a display device, for a programmer comprising a set of program cams, arranged to be automatically driven in rotation and to implement several programs established successively, and a selector element mounted integral in rotation with a maneuvering axis. whose angular positioning makes it possible to choose one of said programs, comprising:
  • a control member arranged to control a movable contact moving in one or the other of two positions,
  • - The member being arranged to, under the action of the selector element, cooperate with means for starting the set of cams, be moved along the operating axis in one direction, and thus move the contact movable from one position to the second,
  • the member comprising means for reversing the movement of the movable contact, from the second position to the first, arranged to, under the action of return means, allow the movement in the other direction of the member, the along the maneuvering axis.

On utilise un tel dispositif notamment sur les programmateurs de machines à laver.Such a device is used in particular on programmers of washing machines.

Le déplacement du contact mobile en position de démarrage vise à établir le contact d'alimentation d'un micromoteur électrique qui par l'intermédiaire d'un réducteur mécanique va entraîner en rotation continue l'ensemble de cames, ou le bloc-cames du programmateur, pour l'amener rapidement dans la position de départ d'un des programmes choisi initialement par l'affichage normal.The displacement of the movable contact in the starting position aims at establishing the supply contact of an electric micromotor which by means of a mechanical reduction gear will drive in continuous rotation the set of cams, or the cam block of the programmer. , to quickly bring it to the starting position of one of the programs initially chosen by the normal display.

Une fois cette position rejointe, le dispositif commande l'inversion brusque du contact afin de rétablir le circuit de fonctionnement normal du programmateur en rotation pas à pas. Afin d'obtenir une inversion rapide du contact garantissant un fonctionnement sûr du dispositif d'affichage, il est nécessaire que le mouvement axial de l'organe de commande, déterminé à la fin du parcours de rattrapage, s'effectue de manière nette et quasi instantanée.Once this position is reached, the device controls sudden reversal of the contact in order to restore the normal operating circuit of the programmer in step-by-step rotation. In order to obtain a rapid reversal of the contact guaranteeing safe operation of the display device, it is necessary that the axial movement of the control member, determined at the end of the take-up course, be carried out clearly and almost instant.

On connait déjà des dispositifs du type définis ci-dessus, notamment par le document FR-A-2 561 421. Dans le dispositif de ce document, l'organe de commande est un levier de commande pourvu d'un bec d'extrémité pouvant chuter dans une encoche ménagée sur une piste circulaire d'une came de démarrage du bloc-cames. Pour que l'inversion du contact soit rapide, il est prévu de donner au bec et à une lumière associée sur l'élément sélecteur une forme particulière, qui interdit l'engagement du bec dans l'encoche avant que la position angulaire du bloc cames n'ait rejoint et par conséquent coïncide exactement avec la position affichée de démarrage du programme sélectionné.Devices of the type defined above are already known, in particular from document FR-A-2 561 421. In the device of this document, the control member is a control lever provided with an end spout which can be fall into a notch formed on a circular track of a cam for starting the cam block. So that the reversal of the contact is rapid, it is planned to give the spout and an associated light on the selector element a particular shape, which prohibits the engagement of the spout in the notch before the angular position of the cam block has not joined and therefore exactly coincides with the displayed starting position of the selected program.

Pour ce faire, le bec, outre qu'il comporte un flanc incliné lui imposant, lors de l'action manuelle d'affichage, une réaction axiale de dégagement hors de l'encoche, présente également une section transversale de forme arrondie particulière lui communiquant un léger mouvement radial de réaction élastique sous l'effet de la rotation manuelle de l'élément sélecteur.To do this, the spout, in addition to having an inclined flank imposing on it, during the manual display action, an axial reaction of release from the notch, also has a cross section of particular rounded shape communicating to it a slight radial elastic reaction movement under the effect of the manual rotation of the selector element.

Ce mouvement radial est obtenu grâce à un certain degré de liberté prévu dans l'articulation du levier de commande sur l'élément sélecteur, ainsi qu'à la présence d'un ressort de rappel qui tend à ramener ce levier et son bec dans la position initiale.This radial movement is obtained thanks to a certain degree of freedom provided in the articulation of the control lever on the selector element, as well as to the presence of a return spring which tends to bring this lever and its spout back into the initial position.

Ainsi, le dispositif du document FR-A-2 561 421 se caractérise par une came de démarrage spéciale, un organe de commande monté sur ressort et un usinage particulier de la came de sélection. Ce dispositif est donc onéreux et peu fiable, du fait de sa complexité.Thus, the device of document FR-A-2 561 421 is characterized by a special starting cam, a control member mounted on a spring and a particular machining of the selection cam. This device is therefore expensive and unreliable, due to its complexity.

Bien que l'invention de la présente demande ait été réalisée dans un but de perfectionner un dispositif d'affichage pour programmateur pourvu de moyens de démarrage d'un moteur d'avance rapide et de moyens d'inversion brusque pour la mise en route d'un moteur pas à pas de déroulement de programme, la demanderesse entend déjà revendiquer un dispositif perfectionné qui soit fonctionnel et simple, c'est-à-dire sans ressort ni came de démarrage.Although the invention of the present application has been carried out with the aim of perfecting a display device for a programmer provided with means for starting a fast-forward motor and means for sudden reversal for starting up a 'A program progress stepping motor, the applicant already intends to claim an improved device which is functional and simple, that is to say without spring or starting cam.

Ainsi, la présente invention concerne un dispositif du type mentionné ci-dessus, caractérisé par le fait que les moyens de démarrage sont ménagés dans la paroi interne parallèle à l'axe de manoeuvre de l'ensemble de cames, et l'organe de commande comporte au moins un bras rigide relié élastiquement à un moyeu monté libre en translation sur l'axe de manoeuvre et incliné par rapport à cet axe entre l'élément sélecteur et le moyeu.Thus, the present invention relates to a device of the type mentioned above, characterized in that the starting means are provided in the internal wall parallel to the operating axis of the cam assembly, and the control member comprises at least one rigid arm connected elastically to a hub mounted free in translation on the operating axis and inclined relative to this axis between the selector element and the hub.

Dans la forme de réalisation préférée du dispositif de l'invention, l'organe de commande comporte plusieurs paires d'un bras rigide et d'un bras souple, s'étendant à travers des lumières ménagées dans l'élément sélecteur, les extrémités libres des bras rigides sont pourvues de rampes de palpage agencées pour coopérer avec des encoches de démarrage ménagées dans la paroi interne axiale de l'ensemble de cames, et les bras rigides et souples sont reliés par paire au moyeu par une zone souple et élastique de faible épaisseur.In the preferred embodiment of the device of the invention, the control member comprises several pairs of a rigid arm and a flexible arm, extending through openings made in the selector element, the free ends rigid arms are provided with probing ramps arranged to cooperate with starting notches formed in the axial internal wall of the cam assembly, and the rigid and flexible arms are connected in pairs to the hub by a flexible and elastic zone of low thickness.

L'invention sera bien comprise à la lecture de la description qui suit d'un exemple de réalisation illustrée par le dessin annexé dans lequel :

  • La figure 1 représente une coupe du dispositif correspondant à la première position de la pièce de commande;
  • la figure 2 est une coupe, identique à la figure 1, correspondant à la seconde position de la pièce de commande;
  • la figure 3 est une vue en plan de la pièce de commande disposée dans le diamètre interne du bloc cames;
  • la figure 4 représente le fonctionnement d'un bras au cours de la rotation du sélecteur.
The invention will be clearly understood on reading the following description of an exemplary embodiment illustrated by the appended drawing in which:
  • Figure 1 shows a section of the device corresponding to the first position of the control part;
  • Figure 2 is a section, identical to Figure 1, corresponding to the second position of the control part;
  • Figure 3 is a plan view of the control part disposed in the internal diameter of the cam block;
  • Figure 4 shows the operation of an arm during the rotation of the selector.

Un programmateur de machine à laver se caractérise essentiellement par un bloc cames programmes 9, entraîné en pas à pas, de façon connue par un ensemble motoréducteur et un cliquet, non représentés sur les figures. Par ailleurs, un second moteur dont le pignon engrène, par l'intermédiaire d'un dispositif type roue libre, avec une couronne dentée du bloc-cames est alimenté au travers d'un contact mobile double 7. C'est ce contact qui commande soit l'un soit l'autre de ces moteurs au moment de la sélection manuelle d'un programme obtenue par la rotation de l'axe 1, dépassant de la face avant 10 du programmateur. Cet axe est solidaire de l'élément sélecteur 2 qui sert également au centrage du bloc cames 9. L'organe de commande 3 est centré librement par son moyeu 35 sur l'axe 1.A washing machine programmer is essentially characterized by a program cam block 9, driven step by step, in a known manner by a geared motor unit and a pawl, not shown in the figures. Furthermore, a second motor, the pinion of which meshes, by means of a freewheel type device, with a toothed ring of the cam block is supplied through a double movable contact 7. It is this contact which controls either one or the other of these motors at the time of the manual selection of a program obtained by the rotation of the axis 1, protruding from the front face 10 of the programmer. This axis is integral with the selector element 2 which also serves for centering the cam block 9. The control member 3 is freely centered by its hub 35 on the axis 1.

Cet organe possède plusieurs bras en étoile, par exemple trois, qui passant au travers de lumières prévues dans l'élément sélecteur 2 peuvent se loger dans des encoches correspondantes ménagées sur la partie interne parallèle à l'axe 1, du bloc cames 9. La liaison de chaque bras avec le moyeu 35 est assurée par une zone 36 de faible épaisseur. Cette liaison permet une souplesse, ou élasticité, axiale des bras par rapport au moyeu mais pas de souplesse radiale. Le moyeu 35 est, par construction, déporté hors du plan défini par les extrémités des bras en position dans les encoches du bloc cames, et les bras s'étendent donc entre l'élément sélecteur 2 et le moyeu 35.This member has several star arms, for example three, which passing through lights provided in the selector element 2 can be housed in corresponding notches formed on the parallel internal part. to axis 1, of the cam block 9. The connection of each arm with the hub 35 is ensured by an area 36 of small thickness. This connection allows axial flexibility, or elasticity, of the arms relative to the hub but no radial flexibility. The hub 35 is, by construction, offset outside the plane defined by the ends of the arms in position in the notches of the cam block, and the arms therefore extend between the selector element 2 and the hub 35.

Le sens de ce déport est prévu de manière à ce que lorsqu'on applique un effort sur les bras, le moyeu 35 glisse sur l'axe 1 dans le sens de la flèche P1 représentée figure 2.The direction of this offset is provided so that when a force is applied to the arms, the hub 35 slides on the axis 1 in the direction of the arrow P 1 shown in FIG. 2.

Chaque bras incliné par rapport à l'axe 1 est constitué par une paire de deux éléments, un élément rigide 34, 33, 32, pourvu d'une rampe de palpage 38 et un élément souple d'inversion, sous la forme d'un bras radial 31.Each arm inclined with respect to the axis 1 is constituted by a pair of two elements, a rigid element 34, 33, 32, provided with a feeler ramp 38 and a flexible inversion element, in the form of a radial arm 31.

Chaque rampe 38 d'un élément rigide coopère avec une rampe de démarrage 91 du bloc cames et chaque élément souple coopère avec une encoche d'inversion à chute brusque 92.Each ramp 38 of a rigid element cooperates with a starting ramp 91 of the cam block and each flexible element cooperates with a sudden fall reversal notch 92.

Le fonctionnement d'un bras, tel que représenté figure 4, est le suivant. Lorsque l'élément sélecteur est entrainé dans le sens de la flèche F2, il vient en appui sur l'élément rigide qui glisse sur la rampe 91 tandis que l'élément souple 31 plie radialement et sort de l'encoche 92.The operation of an arm, as shown in Figure 4, is as follows. When the selector element is driven in the direction of arrow F 2 , it bears on the rigid element which slides on the ramp 91 while the flexible element 31 bends radially and leaves the notch 92.

Ce mouvement a pour effet de faire glisser le moyeu 35 le long de l'axe 1 dans le sens de la flèche Fl, ce qui fait pivoter un premier levier 5, agissant sur un second levier multiplicateur 6 qui actionne le contact 7 de sa première position à la seconde. Ce contact faisant démarrer le moteur d'avance rapide, le bloc cames 9 rattrape les bras de la pièce de commande. Pendant ce mouvement, chaque élément souple radial d'inversion 31 qui a repris sa position rectiligne, glisse sur la paroi interne 93 de l'ensemble de cames avant de retomber de façon brusque dans chaque encoche 92. Ceci permet d'annuler le rôle des rampes 38 et 91 et d'actionner rapidement le contact 7 de sa deuxième position à la première, après que le moyeu 35, sous l'action de l'élasticité de zones de liaison 36 ait glissé dans l'autre sens, opposé à celui de la flèche F1, le long de l'axe 1.This movement has the effect of sliding the hub 35 along the axis 1 in the direction of the arrow F l , which rotates a first lever 5, acting on a second multiplier lever 6 which actuates the contact 7 of its first position to second. With this contact starting the fast forward motor, the cam block 9 catches up with the arms of the control part. During this movement, each flexible radial inversion element 31 which has returned to its rectilinear position, slides on the internal wall 93 of the set of cams before suddenly falling back into each notch 92. This makes it possible to cancel the role of the ramps 38 and 91 and quickly actuate the contact 7 from its second position to the first, after the hub 35, under the action of the elasticity of connection zones 36 has slid in the other direction, opposite to that of arrow F 1 , along axis 1.

Les trois bras sont avantageusement, mais non obligatoirement disposés à 120°. Pour éviter d'avoir trois positions à 120° permettant la chute des bras, chacun des éléments rigides 32, 33, 34 a une largeur différente, associée à une largeur correspondante des encoches prévues dans le bloc cames 9, et les éléments souples 31 des trois paires d'éléments sont espacés angulairement, de leurs éléments rigides 32, 33, 34 associés, de largeurs différentes, afin de n'obtenir qu'une possibilité de fonctionnement sur 360°.The three arms are advantageously, but not necessarily arranged at 120 °. To avoid having three positions at 120 ° allowing the arms to fall, each of the rigid elements 32, 33, 34 has a different width, associated with a corresponding width of the notches provided in the cam block 9, and the flexible elements 31 of the three pairs of elements are angularly spaced, from their associated rigid elements 32, 33, 34, of different widths, so as to obtain only a possibility of operation over 360 °.

Ce dispositif permet de réaliser des programmateurs de machines à laver automatiques ayant un affichage à présélection manuelle pour le choix des programmes, qui soit fiable et peu onéreux.This device enables programmers of automatic washing machines having a display with manual preselection for the choice of programs, which is reliable and inexpensive.
