The door has a locking mechanism comprising a keeper (24) fixed to the door (21), which is hinged to the drum, a catch (25) and a tumbler (26) fastened mechanically to the drum (23) so they have a degree of rotary freedom, and release mechanism (29, 291). The door is held closed by the catch engaging with the keeper, and the catch and tumbler cooperating so that the tumbler locks the catch in the keeper by virtue of its return spring. The catch is released from the keeper when the tumbler is rotated by the release mechanism, which is in the form of an electromagnet (29) with its tip (291) moving into the drum when fed with a current at the end of the washing/drying cycle.

Description

La présente invention concerne un dispositif de fermeture et d'ouverture du tambour d'une machine à laver ou à sécher le linge à chargement par le dessus. Elle s'applique aussi bien aux machines à laver ou à sécher qu'aux machines qui lavent et qui sèchent à la fois.The present invention relates to a closure device and opening the drum of a washing or drying machine top loading. It applies equally to washing machines or dry only with machines that wash and dry at the same time.

Un inconvénient d'une machine à laver ou à sécher le linge à chargement par le dessus, notamment par rapport à une machine à chargement frontal, est qu'il est nécessaire d'ouvrir au moins deux portes. L'utilisateur doit en effet ouvrir au moins la porte de la carcasse de la machine et le portillon du tambour. Cette action supplémentaire qu'est l'ouverture du tambour n'est pas aussi anodine qu'il y paraít. D'abord, elle complique la tâche de l'utilisateur qui accède généralement au tambour d'une machine en étant par ailleurs chargé de linge. L'économie d'une ouverture supplémentaire, qui de plus est en règle générale non aisée, est donc bénéfique pour l'utilisateur. Ensuite, comme il vient d'être mentionné, l'ouverture du tambour est souvent assez compliquée, et même éventuellement blessante, en particulier au niveau des doigt et notamment des ongles. Cette difficulté d'ouverture, mais aussi de fermeture, provient notamment du fait que le portillon du tambour est constitué de deux battants. L'ouverture ou la fermeture d'un portillon à deux battants, elle n'est pas naturelle et l'utilisateur doit apprendre à l'utiliser, plus précisément s'habituer à son maniement. La difficulté est encore accrue par le fait que les deux mains sont nécessaires à la manipulation. Par ailleurs, un inconvénient lié à l'existence de deux battants réside dans la possibilité de mettre ces deux battants en équilibre et donc de croire avoir bien fermé le portillon. Il y a ainsi un risque que la machine soit mise en marche alors que le portillon n'est en fait pas correctement fermé et qu'il s'ouvre en fonctionnement. Pour éviter une telle ouverture du portillon, alors que la machine est en marche, les systèmes connus ont des ressorts de rappel très forts, donc agressifs vis-à-vis d'un utilisateur. Ils ont par ailleurs des pièces de sécurité telles que des moyens d'arrêt ou des boutons qui augmentent le coût de réalisation d'un tambour.A disadvantage of a washing machine or dryer top loading, especially with respect to a front loading, is that it is necessary to open at least two doors. The user must in fact open at least the door of the carcass of the machine and the drum door. This additional action that is the opening of the drum is not as harmless as it seems. First she complicates the task of the user who generally accesses the drum of a machine being also loaded with laundry. The economy of a additional opening, which is generally not easy, is therefore beneficial for the user. Then, as just mentioned, opening the drum is often quite complicated, and even possibly hurtful, in particular on the fingers and in particular nails. This difficulty of opening, but also of closure, comes from in particular of the fact that the door of the drum consists of two leaves. The opening or closing of a double leaf gate, it is not natural and the user must learn to use it, more precisely get used to its handling. The difficulty is further increased by the fact that the two hands are required for handling. Furthermore, a drawback related to the existence of two leaves lies in the possibility of putting these two leaves in balance and therefore to believe that you have closed the gate properly. There is thus a risk that the machine will be started when the gate is not in does not close properly and opens in operation. To avoid such a gate opening, while the machine is running, the known systems have very strong return springs, therefore aggressive towards of a user. They also have security items such as stop means or buttons that increase the cost of making a drum.

Enfin, des sondages réalisés auprès d'un échantillon représentatif d'utilisateurs ont montré que cette ouverture du tambour avait un effet anxiogène sur ces utilisateurs, en particulier en raison des risques de blessures précités, mais aussi à cause du bruit ou plus précisément des forts claquements créés par les battants du portillon du tambours sur la cuve lors de l'ouverture, sous l'effet de ressorts à grande force de rappel.Finally, surveys carried out on a representative sample of users have shown that this opening of the drum has an effect anxiety on these users, especially due to the risks of injuries mentioned above, but also due to noise or more specifically loud clicks created by the flaps of the drum door on the tank during of the opening, under the effect of springs with large restoring force.

Le but de l'invention est notamment de supprimer tous ces inconvénients en supprimant par exemple l'étape d'ouverture de la porte du tambour, en prévoyant la possibilité d'une ouverture automatique de cette dernière de telle sorte qu'une fois que l'utilisateur a ouvert la porte de la carcasse d'une machine à laver et/ou à sécher le linge, la porte du tambour soit déjà ouverte et qu'il accède directement au tambour.The object of the invention is in particular to remove all of these disadvantages by removing for example the step of opening the door of the drum, providing for the possibility of automatic opening of this last so that once the user has opened the door to the carcass of a washing machine and / or dryer, the drum door is already open and has direct access to the drum.

A cet effet, l'invention a pour objet un dispositif de fermeture et d'ouverture du tambour d'une machine à laver et/ou à sécher le linge, caractérisé en ce qu'il comporte un battant pivotant par rapport au tambour par une charnière, une gâche solidaire mécaniquement du battant, un pêne et une gâchette solidaires mécaniquement du tambour avec un degré de liberté en rotation, et des moyens de déverrouillage, le battant étant maintenu en position fermée par l'engagement du pêne dans la gâche, le pêne et la gâchette coopérant de telle sorte que la gâchette bloque le pêne dans la gâche sous l'effet du ressort de rappel du pêne qui maintient ce dernier en appui contre la gâchette, et de telle sorte que la rotation de la gâchette provoquée par les moyens de déverrouillage libère le pêne de la gâche.To this end, the invention relates to a closure device and opening the drum of a washing and / or drying machine, characterized in that it has a pivoting leaf relative to the drum by a hinge, a keeper mechanically secured to the leaf, a bolt and a trigger mechanically secured to the drum with a degree of freedom in rotation, and unlocking means, the leaf being maintained in the closed position by engaging the latch in the strike, the bolt and trigger cooperating so that the trigger blocks the bolt in the keeper under the effect of the return spring of the bolt which maintains this last pressing against the trigger, and so that the rotation of the trigger caused by the unlocking means releases the bolt from the spoils.

L'invention a notamment pour principaux avantages qu'elle permet une ouverture automatique mais aussi une ouverture manuelle simple du tambour, qu'elle est indépendante du type de motorisation utilisé pour l'entraínement du tambour, qu'elle permet le blocage du tambour lors du chargement ou déchargement du linge, et qu'elle n'exige pas d'efforts particuliers pour la fermeture et/ou l'ouverture.The main advantages of the invention are that it allows automatic opening but also manual opening simple of the drum, that it is independent of the type of motorization used for driving the drum, it allows the blocking of the drum during loading or unloading the laundry, and it requires no effort particular for closing and / or opening.

D'autres caractéristiques et avantages de l'invention apparaítront à l'aide de la description qui suit, faite en regard de dessins annexés qui représentent :

  • la figure 1, de façon schématique, une machine à laver ou sécher le linge à l'état ouvert ;
  • la figure 2, une solution de fermeture selon l'art antérieur ;
  • la figure 3, des éléments d'un exemple de réalisation possible d'un dispositif selon l'invention ;
  • les figures 4a et 4b, un exemple de réalisation d'un dispositif selon l'invention dans le cas d'une ouverture automatique ;
  • les figures 5a et 5b, un exemple de réalisation d'un dispositif selon l'invention dans le cas d'une ouverture manuelle.
Other characteristics and advantages of the invention will become apparent with the aid of the description which follows, given with reference to the appended drawings which represent:
  • Figure 1, schematically, a washing machine or dryer laundry in the open state;
  • Figure 2, a closure solution according to the prior art;
  • Figure 3, elements of a possible embodiment of a device according to the invention;
  • Figures 4a and 4b, an embodiment of a device according to the invention in the case of an automatic opening;
  • Figures 5a and 5b, an embodiment of a device according to the invention in the case of manual opening.

La figure 1 illustre, de façon schématique une machine 1, par exemple à laver, à l'état ouvert. Plus précisément, la porte 2 de la carcasse est ouverte, ainsi que le portillon du tambour 5 dont un battant 3 est représenté. Ce dernier est, en position ouverte, appuyé et maintenu sur le bord 4 de la cuve par des ressorts de rappel pour permettre à l'utilisateur de charger ou de décharger le tambour sans nécessité de maintenir le portillon ouvert. Les battants du portillon passent de la position fermée à cette position ouverte, d'abord sous l'effet d'un déverrouillage effectué par l'utilisateur, puis des ressorts de rappel. Il s'ensuit un claquement, de fort bruit, des battants sur les bords de la cuve et éventuellement de la carcasse. Ce bruit est anxiogène pour les utilisateurs. Cette gêne s'ajoute à celle occasionnée par l'ouverture supplémentaire du portillon du tambour.FIG. 1 schematically illustrates a machine 1, by example to be washed, in the open state. More specifically, door 2 of the carcass is open, as well as the door of the drum 5, a leaf 3 of which is represented. The latter is, in the open position, supported and maintained on the edge 4 of the tank by return springs to allow the user to load or unload the drum without the need to maintain the gate open. The flaps of the gate pass from the closed position to this open position, first under the effect of an unlocking carried out by user, then return springs. There is a loud click noise, leaves on the edges of the tank and possibly the carcass. This noise is worrying for users. This discomfort is added to that caused by the additional opening of the drum door.

La figure 2 illustre une solution connue pour la fermeture du tambour d'une machine à laver ou à sécher le linge, solution similaire à tous les types de machines que l'on trouve sur le marché. La fermeture comporte deux battants. Ces battants 11, 12 pivotent sur eux-mêmes à l'aide de charnières 13, 14 reliées à la virole 15. Le verrouillage des deux battants est assuré par exemple par un loquet 16 fixé à l'un des battants, ce loquet venant s'accrocher à l'autre battant. Le maintien de l'accrochage entre les deux battants provient de la force exercée, vers l'ouverture, par des ressorts de rappel 17, 18 sur ces battants. Comme il a été indiqué précédemment, pour des raisons de sécurités de fermeture, ces ressorts possèdent une grande force de rappel. Lors du décrochage du loquet 16 par un utilisateur, les deux battants effectuent un mouvement violent vers leur position d'ouverture sous l'effet des ressorts de rappel 17, 18.Figure 2 illustrates a known solution for closing the drum of a washing machine or dryer, solution similar to all the types of machines found on the market. The closure includes two doors. These leaves 11, 12 pivot on themselves using hinges 13, 14 connected to the ferrule 15. The locking of the two leaves is ensured for example by a latch 16 fixed to one of the leaves, this latch coming to cling to the other wing. Maintaining the bond between two leaves from the force exerted, towards the opening, by springs recall 17, 18 on these leaves. As noted earlier, for reasons of closing security, these springs have a great restoring force. When a latch 16 is lifted by a user, the two wings make a violent movement towards their position opening under the effect of return springs 17, 18.

La figure 3 illustre, par une vue d'ensemble, des éléments d'un exemple de réalisation possible d'un dispositif d'ouverture et de fermeture d'un tambour, d'une machine à laver et/ou sécher le linge, selon l'invention. Ce dispositif comporte un battant 21 que l'on manie par une poignée 30. Le battant 21, représenté en ouverture, pivote par rapport au tambour 23 par une charnière de fixation 22. Une gâche 24 est solidaire mécaniquement du battant 21, en regard d'un pêne 25 solidaire mécaniquement du tambour 23. Une gâchette 26 et une came de déverrouillage 31 sont par ailleurs solidaires mécaniquement du tambour. Plus particulièrement, le pêne 25, la gâchette 26 et la came 31 sont par exemple solidaires mécaniquement d'une pièce mécanique 27 fixée sur le tambour. La gâchette 26 et la came de déverrouillage 31 sont par exemple disposées d'un côté et de l'autre du pêne 25. Tous ces éléments 25, 26, 31 ont un degré de liberté en rotation par rapport au tambour 23 et coopèrent entre eux. Le battant 21 est maintenu en position fermée par l'engagement du pêne 25 dans la gâche 24. Le pêne et la gâchette 26 coopèrent de telle sorte que la gâchette bloque le pêne dans la gâche sous l'effet du ressort de rappel du pêne qui maintient ce dernier en appui contre la gâchette, et de telle sorte que la rotation de la gâchette 26 provoquée par des moyens de déverrouillage, tels que la came 31 ou tout autre moyen, libère le pêne de la gâche. Les figures suivantes illustrent plus précisément des exemples de mises en oeuvre possibles de l'invention.FIG. 3 illustrates, by an overall view, elements of a example of possible embodiment of an opening and closing device a drum, a washing machine and / or drying the laundry, according to the invention. This device comprises a leaf 21 which is handled by a handle 30. The leaf 21, shown in opening, pivots relative to drum 23 by a fixing hinge 22. A keeper 24 is mechanically secured to the leaf 21, opposite a bolt 25 mechanically secured to the drum 23. A trigger 26 and an unlocking cam 31 are also mechanically secured to the drum. More particularly, the bolt 25, the trigger 26 and cam 31 are for example mechanically integral with a mechanical part 27 fixed on the drum. The trigger 26 and the cam unlocking 31 are for example arranged on one side and the other of the bolt 25. All these elements 25, 26, 31 have a degree of freedom in rotation relative to the drum 23 and cooperate with each other. The leaf 21 is maintained in the closed position by engaging the bolt 25 in the keeper 24. The bolt and the trigger 26 cooperate so that the trigger blocks the bolt in the striker under the effect of the bolt return spring which maintains the latter pressing against the trigger, and so that the rotation of the trigger 26 caused by unlocking means, such as the cam 31 or any other means, releases the latch from the keeper. The figures below more specifically illustrate examples of implementation of the invention.

Les figures 4a et 4b illustrent le fonctionnement d'un dispositif selon l'invention dans le cas d'une ouverture automatique. Le dispositif comporte, comme moyens de déverrouillage, un électro-aimant 29 commandé par des moyens électriques non représentés. Ces moyens comportent par exemple un interface pour transformer en signal de puissance, capable d'activer l'électro-aimant, un signal de commande de faible puissance produit par exemple par des circuits numériques, par exemple présents dans le programmateur de la machine. Le signal de commande ouvre et ferme par exemple un interrupteur électronique, du type thyristor ou transistor, pour alimenter ou non en courant l'électro-aimant. En fin de cycle de fonctionnement de cette dernière, l'électro-aimant 29 est alimenté. Le programmateur envoie par exemple à cet effet un signal à l'électro-aimant 29 via l'interface de puissance. Le programmateur envoie par ailleurs par exemple de façon classique un ordre pour faire tourner le tambour 23 à vitesse lente. L'électro-aimant 29 est par exemple fixé à la cuve 28 de la machine, en partie haute, de préférence du côté extérieur de la cuve pour des raisons notamment de sécurité électrique. Il comporte une tige 291 qui se déplace quand la bobine 292 de l'électro-aimant est alimentée en courant. Au repos, en l'absence de courant, la tige est rétractée, plus précisément elle reste en grande partie à l'intérieur de la bobine 292. Si l'électro-aimant est disposé à l'extérieur de la cuve, la tige traverse la cuve 18. Un joint d'étanchéité entre la cuve et la tige peut par exemple être prévu. Cependant, étant donné que l'électro-aimant est en partie haute, ce joint peut ne pas être indispensable. Lorsque l'électro-aimant 29 est alimenté en courant, sa tige 291 se déplace vers l'intérieur de la cuve 28.Figures 4a and 4b illustrate the operation of a device according to the invention in the case of an automatic opening. The device comprises, as unlocking means, an electromagnet 29 controlled by electrical means not shown. These means include for example an interface to transform into a signal power, capable of activating the electromagnet, a control signal low power produced for example by digital circuits, by example present in the programmer of the machine. The signal from command opens and closes for example an electronic switch, of the type thyristor or transistor, to supply or not with current the electromagnet. In end of the latter's operating cycle, the electromagnet 29 is powered. For example, the programmer sends a signal to the electromagnet 29 via the power interface. The programmer sends otherwise for example in a conventional manner an order to rotate the drum 23 at slow speed. The electromagnet 29 is for example fixed to the tank 28 of the machine, in the upper part, preferably on the outside of the tank for reasons including electrical safety. It has a rod 291 which moves when the coil 292 of the electromagnet is supplied with current. At rest, in the absence of current, the rod is retracted, more precisely it remains largely inside the coil 292. If the electromagnet is placed outside the tank, the rod crosses the tank 18. A seal between the tank and the rod can by example be expected. However, since the electromagnet is in upper part, this joint may not be essential. When the electromagnet 29 is supplied with current, its rod 291 moves towards the inside of tank 28.

Les figures 4a et 4b présentent des vues de profil d'éléments tels que représentés par la figure 3. Le pêne 25 tourne autour d'un axe mécanique 251 et la gâchette 26 tourne autour d'un axe mécanique 261. Ces axes mécaniques sont fixés sur le tambour, par exemple sur la pièce mécanique 27 précitée. Ils sont parallèles entre eux et sensiblement orthogonaux à la direction de déplacement de la tige 291. La rotation de la gâchette 26 provoque par ailleurs la rotation du pêne 25, grâce à des profils bien déterminés de ces pièces 25, 26 tels qu'illustrés par les exemples de réalisation présentés par les figures 4a et 4b.Figures 4a and 4b show side views of elements such as shown in Figure 3. The bolt 25 rotates around an axis mechanical 251 and the trigger 26 rotates about a mechanical axis 261. These mechanical axes are fixed on the drum, for example on the workpiece mechanical 27 above. They are parallel to each other and substantially orthogonal to the direction of movement of the rod 291. The rotation of the trigger 26 also causes the bolt 25 to rotate, thanks to profiles well determined from these parts 25, 26 as illustrated by the examples of embodiment shown in Figures 4a and 4b.

La figure 4a montre la tige 291 au début de son déplacement, après l'ordre d'activation de l'électro-aimant 29. Le tambour est encore fermé, c'est-à-dire que sont battant 21 est encore en position fermée. Dans cette position, le pêne 25 est engagé dans la gâche 24, ce qui maintient le battant fermé. Le pêne 25 coopère par ailleurs par deux faces 41, 42 avec la gâchette 26, les deux faces 41, 42 du pêne étant en contact avec l'une ou l'autre de deux faces 43, 44 de la gâchette 26, selon la position en rotation de cette dernière. Sur la figure 4a, lorsque le pêne est maintenu dans la gâche 24, une première face 41 du pêne est en appui sur une première face 43 de la gâchette. Le pêne 25 comporte un ressort de rappel non représenté, qui tend à maintenir la face 41 du pêne au contact de la face 43 de la gâchette 26. L'ensemble constitué du pêne et de la gâchette est donc dans une position relative stable sous l'effet du ressort de rappel du pêne qui force l'appui de ce dernier contre la gâchette. La gâchette bloque en fait le pêne dans la gâche 24. FIG. 4a shows the rod 291 at the start of its movement, after the activation order of the electromagnet 29. The drum is still closed, that is to say that the leaf 21 is still in the closed position. In this position, the bolt 25 is engaged in the strike 24, which keeps the shutter closed. The bolt 25 also cooperates on two faces 41, 42 with the trigger 26, the two faces 41, 42 of the bolt being in contact with one or the other of two faces 43, 44 of the trigger 26, according to the rotational position of the latter. In Figure 4a, when the bolt is held in the keeper 24, a first face 41 of the bolt is supported on a first face 43 of the trigger. The bolt 25 includes a return spring not shown, which tends to keep the face 41 of the bolt in contact with the face 43 of the trigger 26. The assembly consisting of the bolt and the trigger is therefore in a stable relative position under the effect of the bolt return spring which forces the latter to press against the trigger. The trigger actually blocks the latch in strike 24.

La figure 4b montre la même tige 291 en fin de course ou presque. Dans ce cas, la gâchette 26, qui tourne avec le tambour 23 selon un sens F, vient en butée sur la tige 291 de l'électro-aimant. Grâce à la force induite par la rotation du tambour, la gâchette pivote autour de son axe de rotation 261 jusqu'à libérer le pêne 25 de la gâche 24, le pêne étant éloigné de la gâche sous l'action de son ressort de rappel. En se libérant de la gâche, le pêne permet l'ouverture du battant 21 sous l'effet de son ressort de rappel, non représenté et placé au niveau de la charnière 22. Le ressort de rappel du battant n'a pas besoin pour cette ouverture de présenter une très grande force contrairement au cas d'un portillon classique à deux battants qui nécessitent des ressorts ayant de très grandes forces de rappel, pour notamment empêcher leur ouverture durant la rotation du tambour. Le ressort de rappel du battant 21 ne sert ici qu'à entraíner son ouverture lorsque ses moyens de blocage, notamment le pêne et la gâche, le libèrent.FIG. 4b shows the same rod 291 at the end of the stroke or almost. In this case, the trigger 26, which rotates with the drum 23 according to a direction F, abuts on the rod 291 of the electromagnet. Thanks to the force induced by the rotation of the drum, the trigger pivots around its axis of rotation 261 until releasing the bolt 25 from the strike 24, the bolt being distant of the keeper under the action of its return spring. By freeing oneself from the keeper, the bolt allows the leaf 21 to open under the effect of its spring reminder, not shown and placed at the hinge 22. The spring of reminder of the leaf does not need for this opening to present a very great strength unlike in the case of a traditional gate with two leaves which require springs with very large restoring forces, to especially prevent their opening during rotation of the drum. The leaf return spring 21 is only used here to open it when its blocking means, in particular the bolt and the strike, release it.

Lorsque la gâchette pivote et sous l'action de son ressort de rappel, le pêne 25 pivote par exemple lui aussi autour de son axe de rotation 251. Par son mouvement de rotation, le pêne vient bloquer la gâchette en position ouverte, une deuxième face 42 du pêne venant s'appuyer sur une deuxième face 44 de la gâchette. La gâchette et le pêne sont encore ici dans une position stable par l'effet du ressort de rappel du pêne qui maintient ce dernier en appui contre la gâchette. Ce blocage de la gâchette 26 permet notamment de bloquer le tambour en rotation vers l'avant lors du chargement ou déchargement du linge. Pour assurer ce blocage, la gâchette 26 est par exemple en butée sur la cuve 28. A cet effet la gâchette bute sur un ergot qui fait saillie vers l'intérieur de la cuve, ou, comme cela est représenté sur les figures 4a et 4b, la gâchette bute à l'intérieur d'un renfoncement extérieur 281 de la cuve, la tige de l'électro-aimant passant notamment par ce renfoncement 281. La butée de la gâchette dans un creux a notamment l'avantage de permettre un blocage en rotation dans les deux sens, une fois notamment que la tige 291 de l'électro-aimant a regagné sa position de repos à l'intérieur de la bobine 292. Un système quelconque de capteur de position, non représenté, permet par exemple de couper l'alimentation du moteur d'entraínement du tambour une fois que le portillon est ouvert et que le tambour est en position haute, c'est-à-dire que l'ouverture du tambour est en regard de l'ouverture de la machine. When the trigger pivots and under the action of its spring reminder, the bolt 25 pivots for example also around its axis of rotation 251. By its rotational movement, the bolt locks the trigger in open position, a second face 42 of the bolt coming to rest on a second face 44 of the trigger. The trigger and the bolt are still here in a stable position by the effect of the bolt return spring which keeps it pressed against the trigger. This trigger blockage 26 allows in particular to block the drum rotating forwards during the loading or unloading of linen. To ensure this blocking, the trigger 26 is for example in abutment on the tank 28. For this purpose the trigger abuts on a lug which projects towards the inside of the tank, or, as is shown in Figures 4a and 4b, the trigger abuts inside a external recess 281 of the tank, the rod of the electromagnet passing in particular by this recess 281. The stop of the trigger in a hollow has the particular advantage of allowing a rotation lock in both sense, once in particular once the rod 291 of the electromagnet has returned to its rest position inside the coil 292. Any system of position sensor, not shown, allows for example to cut the power to the drum drive motor once the gate is open and the drum is in the high position, i.e. the opening of the drum is opposite the opening of the machine.

Les figures 5a et 5b, par des vues de profil, décrivent une ouverture manuelle d'un dispositif selon l'invention. Cette ouverture manuelle peut par exemple s'ajouter à la possibilité d'ouverture automatique décrite précédemment. Elle peut aussi être mise en oeuvre en l'absence d'ouverture automatique prévue par ailleurs. Le mode d'ouverture tel qu'illustré par ces figures fait intervenir notamment la poignée 30 et la came 31 qui coopèrent entre elles comme moyens de déverrouillage, la came coopère par ailleurs avec la gâchette 26. En ce qui les concerne, le pêne 25 et la gâchette 26 coopèrent entre eux de la même façon que dans le cas de l'ouverture automatique illustrée par les figures 4a et 4b. Par ailleurs, la fermeture du battant 21 est toujours assurée par l'engagement et le maintien du pêne 25 dans la gâche 24. La came de déverrouillage 31 peut tourner autour d'un axe mécanique 311 parallèle aux axes 251, 261 du pêne et de la gâchette, comme ces dernier l'axe 311 de la came est par exemple solidaire du tambour 23 par la pièce mécanique 27 précitée. La poignée 30 peut de son côté tourner autour d'un axe mécanique 311 parallèle aux axes précédents et solidaire mécaniquement du battant 21.Figures 5a and 5b, in side views, describe a manual opening of a device according to the invention. This manual opening can for example be added to the automatic opening possibility described previously. It can also be implemented in the absence of opening automatic provided elsewhere. The opening mode as illustrated by these figures notably involves the handle 30 and the cam 31 which cooperate between them as unlocking means, the cam also cooperates with trigger 26. As far as they are concerned, the bolt 25 and the trigger 26 cooperate with each other in the same way as in the case of opening automatic illustrated in Figures 4a and 4b. Furthermore, the closure of the beating 21 is always ensured by the engagement and maintenance of the bolt 25 in the strike 24. The unlocking cam 31 can rotate around a mechanical axis 311 parallel to axes 251, 261 of the bolt and of the trigger, like the latter the axis 311 of the cam is for example integral with the drum 23 by the aforementioned mechanical part 27. The handle 30 can side turn around a mechanical axis 311 parallel to the previous axes and mechanically secured to the leaf 21.

La figure 5a montre le battant 21 en position de fermeture. En agissant sur la poignée 30, par exemple en faisant tourner son extrémité 302 vers le haut, un utilisateur provoque l'ouverture du battant 21. Par le mouvement de rotation ainsi produit, la poignée 30, par exemple par une de ses extrémités 303, agit sur la came de déverrouillage 31. En particulier, la poignée s'appuie sur la came puis lui impose un mouvement de rotation ou un pivotement. Par ce mouvement de rotation, en prenant appui sur une face 44 de la gâchette 26, la came 31 fait tourner ou pivoter cette dernière de sorte qu'elle libère le pêne 25, qui sous l'effet de son ressort de rappel de désengage alors de la gâche 24, provoquant ainsi l'ouverture du battant 21 sous l'effet de son ressort de rappel, et tel que l'illustre notamment la figure 5b. Il est à noter que dans le cas où seule une ouverture manuelle est prévue, il peut ne pas être nécessaire de prévoir un ressort de rappel pour le battant 21, l'ouverture de ce dernier étant assurée en tirant sur la poignée 30. La figure 5b montre par ailleurs que la gâchette vient par exemple en butée contre la cuve 28 pour permettre le blocage en rotation comme décrit précédemment, la gâchette restant en position ouverte par l'appui d'une face 42 du pêne sur une de ses faces 44, cet appui étant maintenu par l'action du ressort de rappel du pêne.Figure 5a shows the leaf 21 in the closed position. In acting on the handle 30, for example by rotating its end 302 upwards, a user causes the leaf 21 to open. rotational movement thus produced, the handle 30, for example by one of its ends 303 acts on the unlocking cam 31. In particular, the handle rests on the cam then imposes a rotational movement on it or a pivot. By this rotational movement, taking support on one side 44 of trigger 26, cam 31 rotates or pivots the latter by so that it releases the bolt 25, which under the effect of its return spring then disengages the keeper 24, thus causing the leaf 21 to open under the effect of its return spring, and as illustrated in particular in the figure 5b. It should be noted that in the case where only a manual opening is provided, it may not be necessary to provide a return spring for the leaf 21, the latter being opened by pulling on the handle 30. FIG. 5b also shows that the trigger comes, for example, into abutment against the tank 28 to allow locking in rotation as described previously, the trigger remaining in the open position by pressing one side 42 of the bolt on one of its faces 44, this support being maintained by the action of the bolt return spring.

Une pièce mécanique 27, qui est par exemple celle sur laquelle sont fixés les axes de rotation des différents éléments de fermeture et d'ouverture précités, fixée sur le tambour 23 protège ces derniers vis-à-vis du linge présent dans le tambour. Il faut en effet éviter un accrochage du linge sur ces éléments. A cet effet, la pièce mécanique possède par exemple une forme arrondie pour entourer notamment le pêne, la gâchette et la came de déverrouillage.A mechanical part 27, which is for example the one on which are fixed the axes of rotation of the various closing elements and opening, fixed on the drum 23 protects the latter vis-à-vis laundry in the drum. It is indeed necessary to avoid catching the laundry on these items. For this purpose, the mechanical part has for example a rounded shape to surround in particular the bolt, the trigger and the cam unlocking.

Pour verrouiller le portillon en position de fermeture après avoir chargé le linge à l'intérieur du tambour, l'utilisateur n'a qu'à appuyer sur le battant 21 du portillon jusqu'à ce que la gâche 24 vienne faire pivoter le pêne 25, par appui sur une face 52 de ce dernier, de sorte qu'une de ses parties s'engage dans la gâche. Le pêne 25 est ensuite bloqué en rotation, et donc maintenu engagé dans la gâche 24, par l'action de la gâchette 26 qui pivote vers le pêne 25 grâce à un ressort de rappel non représenté. Par ce mouvement de rotation, la gâchette quitte par ailleurs par exemple sa position de butée contre la cuve 28 et libère ainsi la rotation du tambour 23.To lock the gate in the closed position after having loaded the laundry inside the drum, the user only has to press the beating 21 of the gate until the strike 24 comes to rotate the latch 25, by pressing on one face 52 of the latter, so that one of its parts engages in waste. The bolt 25 is then locked in rotation, and therefore kept engaged in strike 24, by the action of trigger 26 which pivots towards the bolt 25 thanks to a return spring not shown. By rotational movement, the trigger also leaves for example its abutment position against the tank 28 and thus frees the rotation of the drum 23.

La tige 291 de l'électro-aimant, qui déverrouille par exemple la gâchette 26 dans le cas d'une ouverture automatique, ou la poignée 30 en association avec la came 31, qui déverrouillent par exemple la gâchette 26 dans le cas d'une ouverture manuelle, peuvent être remplacés par d'autres moyens de déverrouillage.The rod 291 of the electromagnet, which unlocks for example the trigger 26 in the case of automatic opening, or the handle 30 in association with cam 31, which for example unlocks trigger 26 in the case of manual opening, can be replaced by other unlocking means.

L'invention a notamment l'avantage de permettre à la fois une ouverture automatique et manuelle, ou l'une seulement des deux, l'ouverture manuelle ainsi que la fermeture étant simples et ne demandant aucun effort particulier. Elle est par ailleurs indépendante du type de motorisation utilisé pour l'entraínement du tambour.The invention has the particular advantage of allowing both a automatic and manual opening, or only one of the two, opening manual as well as closing being simple and requiring no effort particular. It is also independent of the type of engine used for training the drum.
