Description

La présente invention concerne un programmateur de machine à laver, le linge ou la vaisselle.The present invention relates to a washing machine, laundry or tableware programmer.

Dans un programmateur classique, un ensemble, ou bloc, de cames-programmes, destinées à actionner des lames porte-contact, peut être entraîné en rotation, par l'intermédiare d'une cinématique particulière, par une came dite d'inversion. Les programmes de lavage sont ainsi déterminés par les profils des cames programmes, leur rotation et leur arrêt. La came d'inversion est en permanence entraînée en continu par un moteur synchrone pendant le déroulement des programmes de lavage.In a conventional programmer, a set, or block, of program cams, intended to actuate contact carrier blades, can be driven in rotation, by means of a particular kinematics, by a so-called reversing cam. The washing programs are thus determined by the profiles of the program cams, their rotation and their stopping. The reversing cam is continuously driven continuously by a synchronous motor during the course of the washing programs.

Un cliquet d'entraînement est monté sur la came d'inversion pour entraîner le bloc-cames en rotation pas à pas, la rotation de la came d'inversion d'un tour pouvant entraîner le bloc-cames d'un pas. Le cliquet d'entraînement est monté pivotant entre une position d'entraînement du bloc-cames et une position escamotée, ou de temporisation, dans laquelle il n'entraîne pas le bloc-cames. Le bloc-cames comporte une came dite de temporisation, avec un profil généralement à trois niveaux, qui, par l'intermédiare de la cinématique évoquée ci-dessus, permet de faire pivoter le cliquet d'entraînement en position escamotée pour l'empêcher d'entraîner le bloc-cames pendant un nombre de tours déterminés de la came d'inversion.A drive pawl is mounted on the reversing cam to cause the cam block to rotate step by step, rotation of the reversing cam one turn may cause the cam block to move one step. The drive pawl is pivotally mounted between a position for driving the cam block and a retracted position, or for delaying, in which it does not drive the cam block. The cam block includes a so-called timing cam, with a generally three-level profile, which, by means of the kinematics mentioned above, makes it possible to pivot the drive pawl in the retracted position to prevent it from '' drive the cam block for a specified number of turns of the reversing cam.

Cette cinématique comporte un levier suiveur monté pivotant, sur un axe fixe, pour suivre le profil de la came de temporisation, et duquel sont solidaires en pivotement deux leviers de temporisation. Chacun de ces leviers de temporisation est percé d'une lumière à travers laquelle passe un ergot déplaçable et duquel est solidaire une rampe d'escamotage du cliquet d'entraînement. A chacun des leviers de temporisation sont associés un des niveaux du profil de la came de temporisation et une roue mémoire dont le profil comporte une partie en saillie, définissant une temporisation, et agencée pour coopérer avec son levier associé. Une roue à picot, solidaire en rotation de la came d'inversion, est agencée pour entraîner en rotation pas à pas dans un sens les roues mémoires, par ailleurs rappelées en sens inverse par des moyens élastiques.This kinematics comprises a follower lever pivotally mounted, on a fixed axis, to follow the profile of the timing cam, and which are pivotally connected two timing levers. Each of these timing levers is pierced with a light through which passes a movable lug and which is integral with a ramp for retracting the drive pawl. Each of the timing levers is associated with one of the levels of the profile of the timing cam and a memory wheel, the profile of which has a projecting part, defining a time delay, and arranged to cooperate with its associated lever. A spike wheel, integral in rotation with the reversing cam, is arranged to drive in rotation step by step in one direction the memory wheels, also recalled in the opposite direction by elastic means.

Quand le levier suiveur coopère avec le niveau haut du profil de la came de temporisation, le cliquet d'entraînement n'est pas escamoté et le bloc-cames est entraîné pas à pas.When the follower lever cooperates with the high level of the profile of the timing cam, the drive pawl is not retracted and the cam block is driven step by step.

Quand le levier suiveur vient en contact avec l'un des deux autres niveaux du profil de la came de temporisation, le levier de temporisation associé est pivoté, sa lumière déplace l'ergot et la rampe d'escamotage, ce qui arrête l'entraînement du bloc-cames par le cliquet d'entraînement. Le levier de temporisation considéré coopère alors avec le profil, bas, de la roue mémoire associée pour assurer une fonction anti-retour et permettre ainsi l'entraînement pas à pas de la roue mémoire, jusqu'à ce que le levier de temporisation monte sur la partie en saillie de son profil. Alors, le levier de temporisation pivote en sens inverse, la roue mémoire est rappelée en position initiale, la rampe d'escamotage et l'ergot sont libérés par la lumière du levier, et l'entraînement du bloc-cames par le cliquet reprend.When the follower lever comes into contact with one of the two other levels of the timing cam profile, the associated timing lever is pivoted, its light moves the lug and the retracting ramp, which stops the drive of the cam block by the drive pawl. The timing lever considered then cooperates with the low profile of the associated memory wheel to provide a non-return function and thus allow the memory wheel to be driven step by step, until the timing lever rises on the projecting part of its profile. Then, the delay lever pivots in the opposite direction, the memory wheel is recalled to the initial position, the retracting ramp and the lug are released by the light on the lever, and the camshaft drive is resumed.

Ainsi, avec une came de temporisation à trois niveaux, chacun des deux niveaux bas sélectionne une temporisation, non nulle, dont la durée est déterminée par la longueur du profil bas de la roue mémoire correspondante.Thus, with a three-level timing cam, each of the two low levels selects a non-zero delay, the duration of which is determined by the length of the low profile of the corresponding memory wheel.

Les leviers de mémorisation et les roues mémoires associées sont agencés pour que l'un seulement de ces leviers puisse coopérer avec sa roue mémoire associée, à la fois.The memory levers and the associated memory wheels are arranged so that only one of these levers can cooperate with its associated memory wheel at a time.

Dans ces conditions, on conçoit que, ne disposant que d'un nombre très limité de durées de temporisation, on soit contraint parfois, sauf par conséquent à augmenter le nombre de ces durées et alourdir considérablement la cinématique avec des roues mémoires supplémentaires, ce qui n'est pas souhaitable, à prendre des temporisations d'une durée supérieure à celle strictement utile ou nécessaire. Il en résulte une perte de temps.Under these conditions, we can see that, having only a very limited number of delay times, we are sometimes, except as a consequence of increasing the number of these durations and considerably increasing the kinematics with additional memory wheels, which is not desirable, to take timers of a duration greater than that strictly useful or necessary. This results in a waste of time.

La présente invention vise à pallier cet inconvénient.The present invention aims to overcome this drawback.

A cet effet, la présente invention concerne un programmateur de machine à laver comprenant un bloc de cames-programmes, une came d'inversion entraînée en continu, un cliquet monté pivotant entre une position d'entraînement du bloc de cames en rotation d'un pas et une position escamotée de temporisation, le dit bloc de cames comportant une came de temporisation pourvue d'un profil de sélection de l'une d'une série de temporisations, et des moyens agencés pour déterminer les durées de temporisations et faire pivoter le cliquet d'entraînement du bloc de cames, ces moyens comprenant un levier agencé pour suivre le profil de la came de temporisation, une roue mémoire, une roue à picot solidaire en rotation de la came d'inversion et agencée pour entraîner en rotation la roue mémoire, et un levier de temporisation agencé pour coopérer avec la roue mémoire et le cliquet d'entraînement du bloc de cames, programmateur caractérisé par le fait qu'il comporte une portion de disque en forme de secteur, de largeur angulaire déterminée, montée rotative sur l'axe de la roue mémoire et de rayon égal au rayon externe de la roue, et un cliquet, animé d'un mouvement de bascule et agencé pour entraîner la roue mémoire, la course utile du cliquet étant limitée par la position angulaire de la portion de disque, la portion de disque étant agencée pour, sous l'action du levier suiveur, faire varier la distance angulaire sur laquelle la roue mémoire est entraînée par la roue à picot lors de chaque tour de la came d'inversion.To this end, the present invention relates to a washing machine programmer comprising a block of program cams, a continuously driven reversing cam, a pawl mounted pivotally between a position for driving the cam block in rotation by a pitch and a retracted timing position, said cam block comprising a timing cam provided with a profile for selecting one of a series of timings, and means arranged to determine the timing durations and rotate the cam block drive ratchet, these means comprising a lever arranged to follow the profile of the timing cam, a memory wheel, a spike wheel integral in rotation with the reversing cam and arranged to drive the wheel in rotation memory, and a timing lever arranged to cooperate with the memory wheel and the drive ratchet of the cam block, programmer characterized in that it comprises a portion of sector-shaped disc, of determined angular width, rotatably mounted on the axis of the memory wheel and of radius equal to the external radius of the wheel, and a pawl, rocked and arranged to drive the memory wheel , the useful stroke of the pawl being limited by the angular position of the disc portion, the disc portion being arranged to, under the action of the follower lever, vary the angular distance over which the memory wheel is driven by the wheel to pin during each revolution of the reversing cam.

Ainsi, grâce au programmateur de l'invention, il est facile de prévoir autant de durées de temporisation qu'on le désire.Thus, thanks to the programmer of the invention, it is easy to predict as many delay times as desired.

Avantageusement, le cliquet d'entraînement de la roue mémoire est entraîné dans son mouvement de bascule par un levier monté pivotant sous l'action de l'entraînement en rotation de la roue à picot.Advantageously, the drive pawl of the memory wheel is driven in its rocking movement by a lever pivotally mounted under the action of the rotation drive of the spike wheel.

Avantageusement encore, la portion de disque comporte une échancrure recevant un ergot solidaire du levier suiveur, la position angulaire du levier suiveur déterminant la position angulaire de la portion de disque et le levier de temporisation est monté pivotant et peut coopérer avec une denture à rochet de la roue mémoire, pour assurer une fonction d'anti-retour, et avec le cliquet d'entraînement pour le maintenir en position escamotée de temporisation.Advantageously also, the disc portion comprises a notch receiving a lug secured to the follower lever, the angular position of the follower lever determining the angular position of the disc portion and the timing lever is pivotally mounted and can cooperate with a ratchet toothing of the memory wheel, to ensure a non-return function, and with the drive pawl to keep it in the retracted time delay position.

L'invention sera mieux comprise à l'aide de la description suivante de la forme de réalisation préférée du programmateur de l'invention, en référence aux dessins annexés, sur lesquels :

  • la figure 1 est une vue en perspective éclatée de la cinématique de temporisation du programmateur de l'invention, et
  • la figure 2 est une vue axiale d'une partie de la came d'inversion.
The invention will be better understood using the following description of the preferred embodiment of the programmer of the invention, with reference to the appended drawings, in which:
  • FIG. 1 is an exploded perspective view of the timing kinematics of the programmer of the invention, and
  • Figure 2 is an axial view of part of the reversing cam.

Le programmateur, pour machine à laver, le linge ou la vaisselle, comprend un module arrière et un bloc de cames 41. Le module arrière supporte un moteur d'entraînement, ici un moteur synchrone, et comprend une boîte de contacts destinés à assurer le raccordement électrique avec les autres organes de la machine à laver, ainsi qu'un dispositif de temporisation et d'entraînement du bloc de cames. Le bloc de cames, accolé au module arrière, comprend un certain nombre de cames accolées les unes aux autres et solidaires en rotation les unes des autres, à l'exception de la première came, la came d'inversion 1, qui est entraînée directement à vitesse constante par le moteur et tourne en continu et en permanence pendant le déroulement du programme. La came d'inversion peut entraîner en rotation pas à pas le bloc de cames à l'aide d'un cliquet 37 pouvant entraîner en rotation d'un pas le bloc de cames à chaque tour de la came d'inversion. L'action du cliquet peut être neutralisée pendant un certain temps, la came d'inversion pouvant faire un certain nombre de tours avant d'entraîner à nouveau le bloc de cames, grâce à une chaîne cinématique de temporisation. La chaîne de temporisation comprend le cliquet 37, et des moyens agencés pour déterminer les durées de temporisation et faire pivoter le cliquet 37 en position d'entraînement du bloc de cames, comportant une roue 3, une bascule 5, un cliquet 12, disposé pour coopérer avec une roue mémoire 16, un levier suiveur 21 constituant le levier de sélection de temporisation, une came de temporisation 23, intégrée au bloc de cames, et un levier de temporisation 29.The programmer, for washing machine, laundry or dishes, comprises a rear module and a cam block 41. The rear module supports a drive motor, here a synchronous motor, and includes a contact box intended to ensure the electrical connection with the other parts of the washing machine, as well as a timing and drive device for the cam block. The cam block, attached to the rear module, includes a certain number of cams joined to one another and integral in rotation with one another, with the exception of the first cam, the reversing cam 1, which is driven directly at constant speed by the motor and rotates continuously and continuously during the course of the program. The reversing cam can cause the cam block to rotate step by step using a pawl 37 which can cause the cam block to rotate one step at each revolution of the reversing cam. The action of the pawl can be neutralized for a certain time, the reversing cam being able to make a certain number of turns before driving the block of cams again, thanks to a kinematic timing chain. The timing chain comprises the pawl 37, and means arranged to determine the timing times and rotate the pawl 37 in the driving position of the cam block, comprising a wheel 3, a rocker 5, a pawl 12, arranged for cooperate with a memory wheel 16, a follower lever 21 constituting the timing selection lever, a timing cam 23, integrated in the cam block, and a timing lever 29.

La came d'inversion est constituée d'un manchon 1 multifonctionnel. Il comporte une denture circulaire 101, dans un plan radial, pour son entraînement par le moteur synchrone, par l'intermédiaire d'une denture périphérique externe 102 d'un petit pignon 103. Le cliquet d'entraînement 37 est monté sur le pignon 103, pivotant autour d'un axe 46 excentré sur le pignon 103, entre une position d'entraînement possible du bloc de cames 41, dans laquelle il est rappelé par une lame-ressort 42, et une position escamotée de temporisation. Le manchon d'inversion comporte, dans un autre plan radial, une couronne circulaire pleine 104 pourvue d'une fenêtre 2. Le cliquet d'entraînement 37 est de forme sensiblement parallélépipédique. Il est percé d'un trou dans lequel est logé l'axe 46 monté perpendiculairement et fixé sur le pignon 103 et est animé ainsi d'un mouvement circulaire permanent. Le cliquet 37 comporte deux embouts accolés chacun d'épaisseur sensiblement moitié de l'épaisseur totale du cliquet, un embout arrondi 38 et un embout pointu et effilé 39, l'embout 38 ayant une largeur sensiblement double de celle de l'embout 39. Le ressort 42 exerce son effort, illustré schématiquement sur la figure 1 par un ressort de traction, sur la zone du cliquet comportant les embouts 38 et 39 afin de maintenir l'embout 38 en appui contre la couronne pleine 104 de la came d'inversion 1. La combinaison de la force de rappel exercée par le ressort 42 et du mouvement circulaire de l'axe 46, entraîne le cliquet 37 dans un mouvement excentrique, ici dans le sens des aiguilles d'une montre.The reversing cam consists of a multifunctional sleeve 1. It has a circular toothing 101, in a radial plane, for its drive by the synchronous motor, via an external peripheral toothing 102 of a small pinion 103. The drive pawl 37 is mounted on the pinion 103 , pivoting about an eccentric pin 46 on the pinion 103, between a possible driving position of the cam block 41, in which it is returned by a leaf spring 42, and a retracted position for timing. The reversing sleeve comprises, in another radial plane, a solid circular ring 104 provided with a window 2. The drive pawl 37 is of substantially parallelepiped shape. It is pierced with a hole in which is housed the axis 46 mounted perpendicularly and fixed on the pinion 103 and is thus animated with a circular movement permanent. The pawl 37 comprises two joined end pieces, each of thickness substantially half the total thickness of the pawl, a rounded end piece 38 and a pointed and tapered end piece 39, the end piece 38 having a width substantially double that of the end piece 39. The spring 42 exerts its force, illustrated diagrammatically in FIG. 1 by a tension spring, on the zone of the pawl comprising the end pieces 38 and 39 in order to keep the end piece 38 in abutment against the full crown 104 of the reversing cam 1. The combination of the restoring force exerted by the spring 42 and the circular movement of the axis 46, causes the pawl 37 in an eccentric movement, here in the clockwise direction.

La roue 3, solidaire en rotation de la came d'inversion 1, tourne en continu et en permanence, ici dans le sens contraire à celui des aiguilles d'une montre, avec son axe logé dans un trou du boîtier du programmateur. La roue 3 porte un picot, ou ergot, 4 cylindrique en saillie hors de l'une des faces de la roue, sensiblement à mi-rayon.The wheel 3, integral in rotation with the reversing cam 1, rotates continuously and permanently, here counterclockwise, with its axis housed in a hole in the programmer housing. The wheel 3 carries a cylindrical pin, or lug, 4 projecting from one of the faces of the wheel, substantially at mid-radius.

La bascule 5 comprend, de part et d'autre d'un axe 6, tourillonnant dans un trou du boîtier du programmateur, deux bras 7 et 8, ici sensiblement égaux et approximativement dans le prolongement l'un de l'autre. Le bras 7 vient en appui contre l'ergot 4 sous l'action d'un resort de traction 9 fixé au bras 8, sensiblement à la moitié de sa longueur, et au boîtier. La combinaison de l'action de l'ergot 4 et du rappel élastique du ressort 9 entraîne la bascule, ou levier, 5 dans un mouvement de bascule autour de son axe 6. Le bras 8, à son extrémité opposée à l'axe 6, porte, perpendiculairement à son plan, un ergot 10. Un cliquet 12 est monté pivotant sur l'ergot 10, par l'une de ses extrémités en forme de manchon 13, son autre extrémité comportant un bec 14 destiné à coopérer avec la denture à rochet 25 d'une roue mémoire 16. Un ressort de traction 15, fixé au levier 12 et au boîtier du programmateur, le rappelle vers la roue 16 pour maintenir le bec 14 contre la denture 25 de la roue mémoire 16.The rocker 5 comprises, on either side of an axis 6, journalling in a hole in the programmer housing, two arms 7 and 8, here substantially equal and approximately in the extension of one another. The arm 7 comes to bear against the lug 4 under the action of a traction resort 9 fixed to the arm 8, substantially half of its length, and to the housing. The combination of the action of the lug 4 and the elastic return of the spring 9 causes the rocker, or lever, 5 in a rocking movement around its axis 6. The arm 8, at its end opposite the axis 6 , carries, perpendicular to its plane, a lug 10. A pawl 12 is pivotally mounted on the lug 10, by one of its ends in the form of a sleeve 13, its other end comprising a spout 14 intended to cooperate with the teeth ratchet 25 of a memory wheel 16. A tension spring 15, fixed to the lever 12 and to the housing of the programmer, calls it back to wheel 16 to hold spout 14 against the toothing 25 of memory wheel 16.

La roue mémoire 16 est mobile en rotation autour de son axe 17 logé dans un trou du boîtier du programmateur, et le bec 14 du cliquet 12 peut ainsi la faire tourner en rotation pas à pas, ici dans le sens des aiguilles d'une montre, contre l'action d'un ressort de rappel 27, la roue 16 étant après chaque pas verrouillée en position par une butée anti-retour 31 du levier de temporisation 29 abordé plus loin.The memory wheel 16 is movable in rotation about its axis 17 housed in a hole in the programmer housing, and the spout 14 of the pawl 12 can thus make it rotate in rotation step by step, here in the clockwise direction , against the action of a return spring 27, the wheel 16 being after each step locked in position by a non-return stop 31 of the timing lever 29 discussed below.

Une portion de disque 18 en forme de secteur, de largeur angulaire déterminée, ayant ici un angle d'ouverture de l'ordre de 30°, et de même rayon externe que celui de la roue mémoire 16, est montée libre en rotation coaxialement avec la roue 16 et accolée à l'une des faces de celle-ci. Une échancrure 19 est ménagée sur la côté de cette portion de disque pour coopérer avec un ergot 20 solidaire du levier de sélection des temporisations 21.A portion of disc 18 in the form of a sector, of determined angular width, having here an opening angle of the order of 30 °, and of the same external radius as that of the memory wheel 16, is mounted free in rotation coaxially with the wheel 16 and attached to one of the faces thereof. A notch 19 is provided on the side of this portion of disc to cooperate with a lug 20 secured to the lever for selecting the timers 21.

La roue mémoire 16 comporte, sur sa face en regard de la portion de disque 18 et sur la zone périphérique de celle-ci, une butée 24 de forme sensiblement en tronc de pyramide, à base sensiblement carrée, dont la base est tournée vers l'axe 17 et le sommet situé radialement à la même distance que le sommet de la denture 25. La face 45 de la butée 24, parallèle à l'axe de la roue 16 et tournée vers la portion de disque 18 est inclinée pour former une rampe, la face 28 opposée s'étendant sensiblement dans un plan radial de la roue 16. Une butée 26 est montée rigidement sur le boîtier du programmateur à proximité de la périphérie de la roue 16, avec un doigt s'étendant pour coopérer, sous l'action du ressort 27, avec la face 28 de la butée 24.The memory wheel 16 comprises, on its face opposite the disc portion 18 and on the peripheral zone thereof, a stop 24 of substantially truncated pyramid shape, with a substantially square base, the base of which faces towards the axis 17 and the apex located radially at the same distance as the apex of the toothing 25. The face 45 of the stop 24, parallel to the axis of the wheel 16 and facing the disc portion 18 is inclined to form a ramp, the opposite face 28 extending substantially in a radial plane of the wheel 16. A stop 26 is rigidly mounted on the programmer housing near the periphery of the wheel 16, with a finger extending to cooperate, under the action of the spring 27, with the face 28 of the stop 24.

Le levier de sélection des temporisations 21, de forme générale plate, est monté pivotant, autour d'un axe 43, parallèle à l'axe de la roue 16, et situé à l'une de ses extrémités et logé dans un trou du boîtier du programmateur, sous l'action d'un ressort 22 fixé au levier et au boîtier. L'autre extrémité du levier 21 est recourbée en forme de bec 44 pour venir en appui, sous l'action du ressort 22, contre le profil de la came de temporisation 23 et suivre son profil.The timer selection lever 21, of generally flat shape, is pivotally mounted around an axis 43, parallel to the axis of the wheel 16, and located at one of its ends and housed in a hole in the programmer housing, under the action of a spring 22 fixed to the lever and to the housing. The other end of the lever 21 is bent in the shape of a spout 44 to come to bear, under the action of the spring 22, against the profile of the timing cam 23 and follow its profile.

Le levier de sélection des temporisations 21 comporte un ergot 20, s'étendant parallèlement à l'axe de la roue 16, et logé dans l'échancrure 19 de la portion de disque 18 pour faire varier la position angulaire de cette portion de disque 18 en fonction de la position angulaire du levier suiveur 21.The timing selection lever 21 includes a lug 20, extending parallel to the axis of the wheel 16, and housed in the notch 19 of the disc portion 18 to vary the angular position of this disc portion 18 as a function of the angular position of the follower lever 21.

Le levier de temporisation 29, en forme de fourchette plate tournée vers la roue mémoire 16, est monté pivotant autour d'un axe 30 parallèle à tous les autres axes de rotation et de pivotement évoqués ci-dessus et logé dans un trou du boîtier du programmateur.The timing lever 29, in the form of a flat fork facing the memory wheel 16, is pivotally mounted about an axis 30 parallel to all the other axes of rotation and pivoting mentioned above and housed in a hole in the housing of the programmer.

L'un des bras du levier 29 se termine en forme de dent 33 destinée à venir coopérer avec la face 45 de la butée 24 de la roue 16. Ce même bras comporte une butée 31 s'étendant perpendiculairement à sa face et de section sensiblement triangulaire pour coopérer avec la denture à rochet 25 de la roue mémoire 16, et servir ainsi d'anti-retour pour cette roue mémoire 16.One of the arms of the lever 29 ends in the form of a tooth 33 intended to come to cooperate with the face 45 of the stop 24 of the wheel 16. This same arm comprises a stop 31 extending perpendicular to its face and of substantially section triangular to cooperate with the ratchet teeth 25 of the memory wheel 16, and thus serve as a non-return for this memory wheel 16.

Un ressort de traction 32, fixé sur l'autre bras du levier 29 et sur le boîtier du programmateur, tend à fair pivoter le levier 29, ici dans le sens des aiguilles d'une montre, pour maintenir ainsi la butée 31 en contact avec la denture à rochet 25.A tension spring 32, fixed on the other arm of the lever 29 and on the programmer housing, tends to make the lever 29 pivot, here in a clockwise direction, to thus keep the stop 31 in contact with ratchet teeth 25.

Le bras du levier 29 auquel est fixé le ressort 32 se termine par une rampe 34 coopérant par appui avec un ergot 36 solidaire du cliquet d'entraînement 37. La rampe 34 d'extrémité est adjacente à la surface latérale 35 du bras considéré, s'étendant sensiblement perpendiculairement, et formant aussi rampe.The arm of the lever 29 to which the spring 32 is fixed ends in a ramp 34 cooperating by pressing with a lug 36 integral with the drive pawl 37. The ramp 34 end is adjacent to the lateral surface 35 of the arm in question, extending substantially perpendicularly, and also forming a ramp.

Le cliquet 37 comporte un appendice, s'étendant perpendiculairement à son plan de rotation, et dont l'extrémité porte l'ergot 36 s'étendant perpendiculairement à son plan et pouvant prendre appui contre la rampe 34 du levier de temporisation 29.The pawl 37 comprises an appendage, extending perpendicular to its plane of rotation, and the end of which carries the lug 36 extending perpendicular to its plane and which can bear against the ramp 34 of the timing lever 29.

Ayant décrit la structure de la chaîne de temporisation du programmateur, son fonctionnement peut maintenant être abordé.Having described the structure of the programmer's timing chain, its operation can now be discussed.

La roue 3, qu'on peut appeler roue motrice, solidaire en rotation de la came d'inversion 1, tourne en continu et en permanence. Son ergot, ou picot, 4 coopère par glissement avec le bras 7 du levier 5. Sous l'effet du ressort 9, le levier 5 est animé d'un mouvement de bascule autour de son axe 6. Dans ce mouvement, le bec 14 du cliquet 12, rappelé par le ressort 15 contre la denture à rochet 25 de la roue mémoire 16, peut l'entraîner en rotation sur une distance angulaire égale à la course maximale du levier 5.The wheel 3, which can be called the driving wheel, integral in rotation with the reversing cam 1, rotates continuously and continuously. Its lug, or pin, 4 cooperates by sliding with the arm 7 of the lever 5. Under the effect of the spring 9, the lever 5 is driven in a rocking movement around its axis 6. In this movement, the spout 14 of the pawl 12, returned by the spring 15 against the ratchet teeth 25 of the memory wheel 16, can cause it to rotate over an angular distance equal to the maximum stroke of the lever 5.

La position angulaire du levier de sélection 21 est fixée par le niveau de la came de temporisation 23 sur lequel prend appui le bec 44 du levier 21.The angular position of the selection lever 21 is fixed by the level of the timing cam 23 on which the spout 44 of the lever 21 is supported.

L'ergot 20 du levier 21, logé dans l'échancrure 19 de la portion de disque 18, positionne angulairement ce secteur 18 par rapport à la course du bec 14. Ainsi, en fonction de la position angulaire du levier de sélection 21, le secteur 18 occulte, au regard du bec 14, un certain nombre de dents de la roue mémoire 16, la course active du cliquet 12 correspondant au nombre de dents non occultées. La roue mémoire 16 tourne ainsi pas à pas à une vitesse déterminée par la position angulaire du levier de sélection 21 donc du niveau de temporisation considéré qui détermine la distance angulaire, variable, sur laquelle la roue mémoire 16 est entraînée à chaque tour de la roue motrice 3.The lug 20 of the lever 21, housed in the notch 19 of the disc portion 18, angularly positions this sector 18 relative to the stroke of the spout 14. Thus, depending on the angular position of the selection lever 21, the sector 18 conceals, with regard to the spout 14, a number of teeth of the memory wheel 16, the active stroke of the pawl 12 corresponding to the number of teeth not obscured. The memory wheel 16 thus rotates step by step at a speed determined by the angular position of the selection lever 21, therefore by the considered timing level which determines the distance angular, variable, on which the memory wheel 16 is driven at each revolution of the drive wheel 3.

Sous l'action du ressort 32, la butée 31 du levier de temporisation 29 coopère avec la denture à rochet 25 de la roue mémoire 16 pour assurer sa fonction anti-retour. Tant que cette butée 31 est en contact avec la denture 25, l'ergot 36 du cliquet 37 est en appui sur l'extrémité 34 du levier de temporisation 29. Lorsque la butée 24 arrive en contact avec le levier de temporisation 29, la rampe 45 de cette butée 24 prend appui sur la dent 33 du levier 29 et fait pivoter le levier 29 autour de son axe 30. La butée 31 est alors libérée de la denture 25, la dent 33 s'accroche contre la face arrière 28 de la butée 24, et l'extrémité 34 du levier 29, libère l'ergot 36 du cliquet 37. Sous l'action du ressort 42, l'extrémité arrondie 38 du cliquet 37 vient en appui contre le profil de la couronne pleine 104 de la came d'inversion 1 en rotation, avant de venir se loger dans sa lumière 2 au moment où celle-ci se présente.Under the action of the spring 32, the stop 31 of the timing lever 29 cooperates with the ratchet teeth 25 of the memory wheel 16 to ensure its non-return function. As long as this stop 31 is in contact with the toothing 25, the lug 36 of the pawl 37 is in contact with the end 34 of the timing lever 29. When the stop 24 comes into contact with the timing lever 29, the ramp 45 of this stop 24 bears on the tooth 33 of the lever 29 and makes the lever 29 pivot around its axis 30. The stop 31 is then released from the toothing 25, the tooth 33 hooks against the rear face 28 of the stop 24, and the end 34 of the lever 29, releases the lug 36 of the pawl 37. Under the action of the spring 42, the rounded end 38 of the pawl 37 comes to bear against the profile of the solid crown 104 of the reversing cam 1 in rotation, before coming to lodge in its lumen 2 at the moment when it presents itself.

Par son mouvement excentrique, dans cette position du cliquet, son extrémité pointue 39 vient coopérer avec une dent 40 du bloc de cames 41 et l'entraîne en rotation d'un pas, l'ergot 36 par appui coulissant contre la rampe 35 du levier 29 le faisant pivoter légèrement avant que la dent 33 ne se dégage de la butée 24 de la roue mémoire 16. Sous l'action du ressort 27, la roue mémoire 16 tourne autour de son axe 17, jusqu'à ce que la face 28 de la butée 24 vienne en appui contre la butée fixe 26. C'est la remise à zéro de la roue mémoire.By its eccentric movement, in this position of the pawl, its pointed end 39 cooperates with a tooth 40 of the cam block 41 and causes it to rotate one step, the lug 36 by sliding support against the ramp 35 of the lever 29 causing it to pivot slightly before the tooth 33 emerges from the stop 24 of the memory wheel 16. Under the action of the spring 27, the memory wheel 16 rotates about its axis 17, until the face 28 of the stop 24 comes to bear against the fixed stop 26. This is the reset of the memory wheel.

La came d'inversion 1 continuant son mouvement de rotation, l'extrémité 38 du cliquet 37 se dégage de l'encoche 2 et pivote en position escamotée de temporisation contre l'action du ressort 42, l'ergot 36 libère le levier de temporisation 29 qui, sous l'action du ressort 32, pivote autour de son axe 30. L'ergot 36 du cliquet 37 revient en butée contre la rampe d'extrémité 34 du levier de temporisation 29 et la butée 31 revient coopérer avec la denture 25 de la roue mémoire 16.The reversing cam 1 continuing its rotational movement, the end 38 of the pawl 37 emerges from the notch 2 and pivots in the retracted timing position against the action of the spring 42, the lug 36 releases the timing lever 29 which, under the action of the spring 32, pivots about its axis 30. The lug 36 of the pawl 37 abuts against the end ramp 34 of the lever time delay 29 and the stop 31 returns to cooperate with the teeth 25 of the memory wheel 16.

Un nouvel incrément de temporisation commence alors.A new timer increment then begins.

Grâce à la chaîne de temporisation décrite ci-dessus, le nombre des temporisations peut être important. Il ne dépend que du nombre de niveaux du profil de la came de temporisation 23.Thanks to the timing chain described above, the number of timers can be large. It only depends on the number of levels of the profile of the timing cam 23.

Le programmateur de l'invention est particulièrement bien adapté aux machines à laver modernes, permettant une optimisation des cycles de lavages donc une multiplication des temporisations.The programmer of the invention is particularly well suited to modern washing machines, allowing optimization of washing cycles and therefore a multiplication of time delays.
