Description

L'invention concerne un dispositif de fermeture automatique de la porte du tambour d'un lave-linge ou d'un sèche-linge, après que le couvercle de la trémie de chargement ait été rabattu.The invention relates to a device for automatically closing the door of the drum of a washing machine or dryer, after the cover of the loading hopper has been folded down.

On connaît déjà différents moyens permettant d'obturer l'ouverture du tambour d'une machine à laver, le plus couramment utilisé étant constitué d'une trappe coulissante, de forme semi-circulaire, de même rayon que celui du tambour, coulissant dans des rails situés à la périphérie dudit tambour, de chaque côté de celui-ci ; l'obturation de l'ouverture étant obtenue par coulissement de la trappe, puis fixation de celle-ci par rapport au tambour, par l'intermédiaire d'une pièce de fermeture à bascule, rappelée en position de fermeture par un ressort.Various means are already known for closing the opening of the drum of a washing machine, the most commonly used being constituted by a sliding hatch, of semi-circular shape, of the same radius as that of the drum, sliding in rails located on the periphery of said drum, on each side thereof; the obturation of the opening being obtained by sliding the hatch, then fixing the latter relative to the drum, by means of a rocking closure part, returned to the closed position by a spring.

Un tel dispositif exige, pour assurer la fermeture du tambour, que la trappe d'obturation soit, tout d'abord, coulissée à la main, dans le sens de la fermeture, puis verrouillée par action manuelle sur la pièce de fermeture, alors que la trappe est maintenue en position adéquate.To ensure the closing of the drum, such a device requires that the shutter flap is firstly slid by hand, in the closing direction, and then locked by manual action on the closing part, while the hatch is kept in the correct position.

On comprend qu'un tel moyen offre la meilleure garantie contre une ouverture intempestive, sous l'action de la force d'inertie centrifuge, en particulier lors de la phase essorage, mais que, par contre, il présente une certaine susceptibilité à l'ouverture au cours des phases de lavage, par inertie sur la trappe, sous l'effet des inversions répétées du sens de rotation du tambour et du frottement du linge contre la face interne de ladite trappe. Un tel moyen ne permet pas, non plus, de s'affranchir de toute possibilité d'entraînement en rotation du tambour, alors que la trappe est restée ouverte, ou a été incomplètement fermée.It is understood that such a means offers the best guarantee against untimely opening, under the action of the centrifugal inertial force, in particular during the spinning phase, but that, on the other hand, it has a certain susceptibility to opening during the washing phases, by inertia on the hatch, under the effect of repeated inversions of the direction of rotation of the drum and the friction of the laundry against the internal face of said hatch. Such a means does not allow, either, to get rid of any possibility of driving the drum in rotation, while the hatch has remained open, or has been incompletely closed.

Dans un cas comme dans l'autre, le linge s'échappe du tambour et se répand entre celui-ci et la cuve, ne tardant pas, ainsi, à provoquer un bourrage, entraînant le blocage du tambour et la mise en avarie de la machine, avec tous les inconvénients que l'on imagine au niveau du système électrique d'entraînement dudit tambour et de la remise en état ultérieure de celui-ci.In either case, the laundry escapes from the drum and spreads between it and the tank, thus not long in causing a jam, resulting in the blocking of the drum and the damage to the machine, with all the drawbacks that one imagines at the level of the electrical system for driving said drum and for the subsequent reconditioning thereof.

La présente invention a pour but de remédier à ces inconvénients. Cette invention, telle qu'elle est caractérisée dans les revendications, résout le problème consistant à créer un dispositif de fermeture de la porte du tambour d'un lave-linge ou d'un sèche-linge, après fermeture du couvercle, avec lequel, d'une part, la porte du tambour et le couvercle de la cuve puissent être rabattus simultanément, avec verrouillage automatique de la porte, dès la mise en rotation du tambour, dans un sens, ou dans l'autre, et, d'autre part, toute ouverture intempestive de ladite porte puisse être annulée quasi-instantanément.The object of the present invention is to remedy these drawbacks. This invention, as characterized in the claims, solves the problem of creating a device for closing the door of the drum of a washing machine or a dryer, after closing the cover, with which, on the one hand, the drum door and the tank cover can be folded down simultaneously, with automatic door locking, as soon as the drum rotates, in one direction or the other, and, on the other apart, any untimely opening of said door can be canceled almost instantaneously.

Le dispositif de fermeture automatique de la porte du tambour d'un lave-linge ou d'un sèche-linge, après que le couvercle ait été rabattu, selon l'invention, se caractérise, principalement, en ce qu'il est constitué, principalement, d'une porte semi-cylindrique, à empreinte de verrouillage et de manoeuvre, articulée par rapport à l'une des extrémités de l'ouverture du tambour, d'un crochet de verrouillage à bascule, à poignée de manoeuvre, articulé par rapport à l'autre extrémité de l'ouverture du tambour, et d'une rampe de fermeture, fixée sur le dessous du couvercle de la trémie de chargement.The device for automatically closing the door of the drum of a washing machine or a dryer, after the cover has been folded down, according to the invention, is characterized, mainly, in that it is made up, mainly, of a semi-cylindrical door, with locking and operating fingerprint, articulated relative to one end of the opening of the drum, of a rocking locking hook, with operating handle, articulated by compared to the other end of the drum opening, and a closing ramp, fixed on the underside of the cover of the loading hopper.

La poignée de manoeuvre du crochet de verrouillage est montée libre en rotation par rapport à un axe, situé sur le devant du bec dudit crochet de verrouillage.The operating handle of the locking hook is mounted to rotate freely with respect to an axis, located on the front of the spout of said locking hook.

Selon un mode de réalisation préférentiel du dispositif selon l'invention, la poignée de manoeuvre du crochet de verrouillage est excentrée par rapport à son axe de rotation.According to a preferred embodiment of the device according to the invention, the operating handle of the locking hook is eccentric relative to its axis of rotation.

La position, la courbure et le relief de la rampe de fermeture de la porte du tambour, fixée sur le dessous du couvercle de la trémie de chargement, sont déterminés pour obtenir, après pivotement du crochet de verrouillage dans le sens de fermeture et entraînement en rotation du tambour dans le sens horaire, la mise en contact de la poignée de manoeuvre du crochet de verrouillage, en appui contre la rampe de fermeture, puis le roulement de ladite poignée de manoeuvre sur ladite rampe de fermeture, jusqu'à engagement complet du bec du crochet de verrouillage dans l'empreinte de verrouillage et de manoeuvre de la porte du tambour.The position, the curvature and the relief of the drum door closing ramp, fixed on the underside of the loading hopper cover, are determined to obtain, after pivoting of the locking hook in the closing direction and driving in rotation of the drum clockwise, bringing the operating handle of the locking hook into contact, pressing against the closing ramp, then rolling said operating handle on said closing ramp, until complete engagement of the beak of the locking hook in the locking and operating impression of the drum door.

Préférentiellement, la base du crochet de verrouillage comporte, au niveau de son axe d'articulation, un linguet de basculement, dirigé vers l'ouverture du tambour, dont la longueur et l'inclinaison sont déterminées pour que, lorsque l'extrémité libre de la porte du tambour vient, lors de son basculement sur l'avant, en contact avec l'extrémité dudit linguet de basculement du crochet de verrouillage, elle provoque, ainsi, le pivotement de celui-ci vers l'empreinte de verrouillage et de manoeuvre de la porte du tambour.Preferably, the base of the locking hook comprises, at its articulation axis, a tilting latch, directed towards the opening of the drum, the length and inclination of which are determined so that, when the free end of the door of the drum comes, during its tilting on the front, in contact with the end of said tilting latch of the locking hook, it thus causes the pivoting of the latter towards the locking and maneuvering imprint from the drum door.

Selon un mode de réalisation simplifié de l'invention, le crochet de verrouillage ne comporte pas de linguet de basculement dudit crochet ; celui-ci est pivoté automatiquement sous l'effet de la rotation du tambour, dans le sens anti-horaire impératif, et par contact avec la trémie.According to a simplified embodiment of the invention, the locking hook does not include a latch for tilting said hook; it is automatically rotated under the effect of the rotation of the drum, in the anti-clockwise imperative direction, and by contact with the hopper.

Les avantages obtenus, grâce à cette invention, consistent, essentiellement, en ceci que la fermeture de la porte du tambour, puis son verrouillage, s'effectuent, après fermeture du couvercle de la cuve, automatiquement, sous l'action de la rotation du tambour, et que le verrouillage de ladite porte de tambour est contrôlé à chaque rotation dudit tambour.The advantages obtained, thanks to this invention, consist essentially in that the closing of the drum door, then its locking, is effected, after closing of the tank cover, automatically, under the action of the rotation of the drum, and that the locking of said drum door is checked at each rotation of said drum.

D'autres caractéristiques et avantages apparaîtront dans la description qui va suivre de deux modes de réalisation du dispositif selon l'invention, donnés à titre d'exemple non limitatif, au regard des dessins annexés, sur lesquels :

  • la figure 1 représente une vue en coupe longitudinale partielle d'une machine en position d'ouverture,
  • la figure 2 représente une vue en coupe longitudinale partielle d'une machine en début de fermeture,
  • la figure 3 représente une vue en coupe longitudinale partielle d'une machine fermée, en cours de verrouillage de la porte du tambour,
  • la figure 4 représente une vue en coupe longitudinale partielle d'une machine, porte du tambour verrouillée,
  • la figure 5 représente une vue en coupe longitudinale partielle d'une machine, équipée d'un mode de réalisation simplifié de l'invention, en position d'ouverture.
Other characteristics and advantages will appear in the following description of two embodiments of the device according to the invention, given by way of nonlimiting example, with regard to the appended drawings, in which:
  • FIG. 1 shows a view in partial longitudinal section of a machine in the open position,
  • FIG. 2 represents a view in partial longitudinal section of a machine at the start of closure,
  • FIG. 3 represents a view in partial longitudinal section of a closed machine, during the locking of the drum door,
  • FIG. 4 represents a view in partial longitudinal section of a machine, door of the drum locked,
  • FIG. 5 represents a view in partial longitudinal section of a machine, equipped with a simplified embodiment of the invention, in the open position.

Les figures représentent un cadre de porte 1, à contre-cadre 2, par rapport auquel est articulée, autour d'un axe 8, une porte 30 de tambour 15, à empreinte de verrouillage et de manoeuvre 31, à ressort de rappel 6, et un crochet de verrouillage 40 à bec 41, à linguet 12, d'axe 9, à ressort de rappel 7 et à poignée de manoeuvre excentrique 5 montée sur un axe 10 ; l'ouverture du tambour 15 étant munie d'un joint d'étanchéité 11 ; la trémie de chargement 16 de la cuve se fermant par l'intermédiaire d'un couvercle 13 à rampe de fermeture 14.The figures represent a door frame 1, against the frame 2, with respect to which a door 30 is hinged about an axis 8 drum 15, with locking and operating imprint 31, with return spring 6, and a locking hook 40 with spout 41, with latch 12, of axis 9, with return spring 7 and with eccentric operating handle 5 mounted on an axis 10; the opening of the drum 15 being provided with a seal 11; the loading hopper 16 of the tank closing by means of a cover 13 with closing ramp 14.

En examinant plus en détail et successivement les figures 1 à 4, on remarque que, lorsque la trémie 16 et le tambour 15 sont ouverts, la porte 30 et le couvercle 13 sont en appui contre le côté arrière de la trémie 16, sous l'effet du ressort de rappel 6 de la porte 30 du tambour 15, alors que le crochet de verrouillage 40 est rappelé, lui, contre le côté avant de la trémie de chargement 16, sous l'effet du ressort de rappel 7. Ainsi, lorsqu'on exerce une action, dans le sens de la fermeture, sur le couvercle 13 de la trémie 16, I'extrémité avant 32 de la porte 30 du tambour 15 vient prendre appui contre l'extrémité du linguet 12 de basculement du crochet de verrouillage 40 et entraîne le pivotement, vers la dite porte 30, dudit crochet de verrouillage 40, jusqu'à mise en contact de la poignée 5 articulée et excentrée du crochet contre la rampe de fermeture 14 du couvercle 13 de la trémie. Ainsi, une rotation du tambour 15, dans le sens horaire (A), provoque le roulement de ladite poignée 5 sur ladite rampe de fermeture 14, jusqu'à pénétration du bec 41 du crochet de verrouillage 40 dans l'empreinte de verrouillage et de manoeuvre 31 de la porte 30 de la trémie 16 ; la rotation de la poignée 5 articulée, au cours de sa rotation, entraîne, compte-tenu de son excentricité, une accentuation de l'engagement de ladite poignée 5 dans l'empreinte 31. On remarque que, lorsque le tambour est entraîné en rotation dans le sens anti-horaire (B), le pivotement complet du crochet de verrouillage 40 et l'engagement du bec 41 dans l'empreinte de verrouillage 31 de la porte 30 du tambour 15 sont obtenus par l'intermédiaire de la base 161 de la trémie 16. A chaque passage de la poignée 5 sous la rampe 14 du couvercle 13, la qualité du verrouillage est contrôlée par le redan 141 de ladite rampe.By examining in more detail and successively Figures 1 to 4, it is noted that, when the hopper 16 and the drum 15 are open, the door 30 and the cover 13 are in abutment against the rear side of the hopper 16, under the effect of the return spring 6 of the door 30 of the drum 15, while the locking hook 40 is biased against the front side of the loading hopper 16, under the effect of the return spring 7. Thus, when 'there is an action, in the closing direction, on the cover 13 of the hopper 16, the front end 32 of the door 30 of the drum 15 comes to bear against the end of the latch 12 for tilting the locking hook 40 and causes the pivoting, towards said door 30, of said locking hook 40, until contacting the articulated handle 5 and eccentric of the hook against the closing ramp 14 of the cover 13 of the hopper. Thus, a rotation of the drum 15, clockwise (A), causes the rolling of said handle 5 on said closing ramp 14, until penetration of the spout 41 of the locking hook 40 into the locking cavity and operation 31 of the door 30 of the hopper 16; the rotation of the articulated handle 5, during its rotation, causes, taking into account its eccentricity, an accentuation of the engagement of said handle 5 in the cavity 31. It is noted that, when the drum is driven in rotation in anti-clockwise (B), the complete pivoting of the locking hook 40 and the engagement of the spout 41 in the locking impression 31 of the door 30 of the drum 15 are obtained by means of the base 161 of the hopper 16. Each time the handle 5 passes under the ramp 14 of the cover 13, the quality of the locking is controlled by the step 141 of said ramp.

En examinant, maintenant, la figure 5, correspondant à un mode de réalisation simplifié de l'invention, on remarque que, compte-tenu de la suppression du linguet 12 du crochet de verrouillage 40, la mise en rotation du tambour 15 doit être impérativement ordonnée dans le sens anti-horaire (B), afin que la fermeture et le verrouillage s'effectuent par la base avant de la trémie 16, sens de rotation qui doit être respecté, aussi, en reprise de cycle, après un arrêt intempestif, provoqué par l'utilisateur ou une panne d'énergie cette rotation devant être intégrée à la commande du moteur d'entraînement de la porte 30 du tambour 15. Dans ce cas, le redan 141 du couvercle 13 n'assure que le contrôle permanent du verrouillage de la porte 30 du tambour 15.By examining, now, FIG. 5, corresponding to a simplified embodiment of the invention, it is noted that, taking into account the removal of the latch 12 from the locking hook 40, the rotation of the drum 15 must imperatively be ordered counterclockwise (B), so that closing and locking are effected by the front base of the hopper 16, direction of rotation which must be respected, also, when the cycle is resumed, after an untimely stop, caused by the user or a power failure, this rotation must be integrated into the control of the drive motor of the door 30 of the drum 15. In this case, the step 141 of the cover 13 ensures only the permanent control of the locking the door 30 of the drum 15.
