Description

La présente invention concerne un système de porte de cuve.The present invention relates to a tank door system.

Elle concerne également un procédé de fermeture et d'ouverture d'une telle porte de cuve, notamment pour machine à laver à tambour rotatif.It also relates to a method of closing and opening such a tank door, in particular for rotary drum washing machine.

La présente invention concerne de manière générale le domaine des machines à tambour rotatif, et en particulier une machine à laver le linge comprenant une cuve de lavage dans laquelle est logé le tambour destiné à contenir le linge. Cette cuve de lavage doit être fermée de façon étanche lors de l'utilisation du lave-linge.The present invention generally relates to the field of rotary drum machines, and in particular a washing machine comprising a washing tub in which is housed the drum for containing the laundry. This wash tub must be tightly closed when using the washing machine.

Afin de réaliser cette étanchéité de la cuve dans la carrosserie de la machine, il existe deux types de fermeture de cuve.In order to achieve this sealing of the tank in the body of the machine, there are two types of tank closure.

Un premier type de fermeture de cuve consiste à fermer de manière étanche la cuve du lave-linge à l'aide d'une porte d'accès montée sur la carrosserie de la machine. Il est alors nécessaire de prévoir une pièce d'étanchéité, par exemple en caoutchouc, permettant de relier de manière étanche la cuve mobile et la porte d'accès de la carrosserie de la machine.A first type of tank closure is to seal the tank of the washing machine with an access door mounted on the body of the machine. It is then necessary to provide a sealing piece, for example of rubber, for sealingly connecting the movable tank and the access door of the bodywork of the machine.

Ce type de solution présente cependant les inconvénients liés à la présence de cette pièce en caoutchouc, encombrante, génératrice de bruit, et gênant les mouvements de la cuve et du tambour suspendus, notamment lors des phases d'essorage du cycle de lavage.This type of solution, however, has the disadvantages associated with the presence of this rubber part, bulky, noise generator, and hindering the movements of the tank and the drum suspended, especially during the spin phases of the wash cycle.

Une deuxième solution consiste à fermer la cuve de manière étanche à l'aide d'une porte fixée sur la cuve. Il est alors nécessaire pour accéder à l'intérieur du tambour d'ouvrir en premier lieu la porte d'accès de la carrosserie, puis la porte de la cuve et enfin les portillons du tambour rotatif. Cet enchaînement pour l'ouverture du lave-linge comporte ainsi trois manipulations.A second solution is to close the tank tightly with a door attached to the tank. It is then necessary to access the interior of the drum first to open the access door of the body, then the door of the tank and finally the doors of the rotating drum. This sequence for opening the washing machine thus comprises three manipulations.

Bien entendu, un enchaînement inverse est nécessaire pour fermer la machine avant de lancer un cycle de lavage.Of course, reverse chaining is necessary to close the machine before starting a wash cycle.

Ces manipulations sont très contraignantes pour l'utilisateur.These manipulations are very restrictive for the user.

On connaît par exemple, tel que décrit dans le document EP 1 298 242, un lave-linge dont les portillons du tambour sont ouverts automatiquement lors de l'ouverture de la porte de cuve, de telle sorte qu'à l'ouverture du lave-linge, seules l'ouverture de la porte d'accès de la carrosserie et de la porte de cuve sont nécessaires. Cependant, pour la fermeture de la machine, trois manipulations telles que décrites précédemment sont requises.For example, as described in EP 1 298 242, a washing machine is known whose drum gates are opened automatically when the tank door is opened, so that at the opening of the lava -linge, only the opening of the access door of the bodywork and the tank door are necessary. However, for closing the machine, three manipulations as described above are required.

La présente invention a pour but de résoudre les inconvénients précités et de proposer un système de porte de cuve facilitant de manière générale l'accès à l'intérieur du tambour pour l'utilisateur.The present invention aims to solve the aforementioned drawbacks and to provide a tank door system generally facilitating access to the interior of the drum for the user.

La présente invention concerne un système de porte de cuve comprenant un vantail adapté à obturer une ouverture dans une paroi de la cuve.The present invention relates to a tank door system comprising a leaf adapted to close an opening in a wall of the tank.

Ce système de porte de cuve comprend des moyens d'actionnement du vantail entre une position ouverte et une position fermée, des premiers moyens de guidage en coulissement d'un premier bord dudit vantail suivant une trajectoire sensiblement tangente à la paroi de la cuve, et des seconds moyens de guidage d'un second bord dudit vantail, opposé audit premier bord, suivant une trajectoire s'étendant à proximité de la paroi de la cuve.This tank door system comprises means for actuating the leaf between an open position and a closed position, first guide means sliding a first edge of said leaf along a path substantially tangent to the wall of the tank, and second means for guiding a second edge of said leaf, opposite said first edge, along a path extending near the wall of the tank.

Ce système de porte de cuve permet d'escamoter le vantail de la cuve contre la paroi de celle-ci.This tank door system allows to retract the leaf of the tank against the wall thereof.

L'accès au tambour à l'intérieur de la cuve est ainsi facilité, et en particulier n'est pas gêné par le vantail en position ouverte.Access to the drum inside the tank is thus facilitated, and in particular is not hindered by the leaf in the open position.

Selon une caractéristique préférée de l'invention, les moyens d'actionnement sont motorisés.According to a preferred characteristic of the invention, the actuating means are motorized.

Ainsi, l'ouverture et la fermeture de la porte de cuve peuvent être automatisées de telle sorte que l'utilisateur de la machine n'a aucune manipulation à réaliser au niveau de cette porte de cuve.Thus, the opening and closing of the tank door can be automated so that the user of the machine has no manipulation to perform at this tank door.

Selon une caractéristique préférée de l'invention, le premier bord du vantail comporte des moyens de verrouillage de ce vantail sur un côté de l'ouverture, ces moyens de verrouillage étant adaptés à être placés alternativement dans une position en prise et une position libérée lorsque le bord du vantail est déplacé suivant un mouvement de va et vient à proximité du côté de l'ouverture.According to a preferred feature of the invention, the first edge of the leaf comprises locking means of this leaf on one side of the opening, these locking means being adapted to be placed alternately in an engaged position and a released position when the edge of the leaf is moved in a movement back and forth near the side of the opening.

Ainsi, le verrouillage et le déverrouillage du vantail au niveau de la cuve peuvent être obtenus par simple déplacement en coulissement du vantail.Thus, the locking and unlocking of the leaf at the tank can be obtained by simply sliding movement of the leaf.

On va décrire tout d'abord en référence à la figure 1 et à la figure 2 une machine à laver le linge conforme à l'invention.We will first describe with reference to Figure 1 and Figure 2 a washing machine according to the invention.

Cette machine à laver 10 est du type à chargement par le dessus. De manière générale, cette machine est adaptée à laver le linge et éventuellement à le sécher.This washing machine 10 is of the top loading type. In general, this machine is suitable for washing the laundry and possibly drying it.

Cette machine à laver 10 comporte une carrosserie 11 comprenant une ouverture 11a d'accès à l'intérieur de la carrosserie. Dans les machines à chargement par le dessus, cette ouverture d'accès 11a est réalisée dans une portion supérieure de la carrosserie, et dans cet exemple, dans un plan supérieur de la carrosserie 11.This washing machine 10 comprises a body 11 comprising an access opening 11a inside the bodywork. In top loading machines, this access opening 11a is made in an upper portion of the body, and in this example, in an upper plane of the bodywork 11.

Une porte d'accès 12 est adaptée à obturer cette ouverture 11a de la carrosserie 11 de la machine, notamment lors du fonctionnement de celle-ci.An access door 12 is adapted to close this opening 11a of the body 11 of the machine, in particular during operation thereof.

En particulier, de manière connue, cette porte d'accès 12 est associée à des moyens de verrouillage dont le fonctionnement est lié au fonctionnement de la machine. Ainsi, en début d'un cycle de lavage, les moyens de verrouillage sont actionnés pour empêcher l'ouverture de la porte d'accès 12. De manière similaire, en fin de cycle de lavage, les moyens de verrouillage sont déverrouillés pour permettre l'ouverture par l'utilisateur de la machine.In particular, in known manner, this access door 12 is associated with locking means whose operation is related to the operation of the machine. Thus, at the beginning of a washing cycle, the locking means are actuated to prevent the opening of the access door 12. Similarly, at the end of the washing cycle, the locking means are unlocked to allow the lock to be unlocked. opening by the user of the machine.

Dans cet exemple de réalisation, et de manière nullement limitative, la porte d'accès 12 est montée pivotante autour d'un axe de rotation 12a solidaire de la carrosserie 11 de la machine.In this embodiment, and in no way limiting, the access door 12 is pivotally mounted about an axis of rotation 12a integral with the body 11 of the machine.

La carrosserie de la machine est adaptée à loger une cuve de lavage 13 qui est adaptée notamment à contenir les différents bains de lavage et de rinçage.The body of the machine is adapted to house a washing tank 13 which is adapted in particular to contain the different washing and rinsing baths.

A l'intérieur de la cuve de lavage est monté de manière connue un tambour 14, mobile en rotation autour d'un axe X lors des différents cycles de lavage, de rinçage et d'essorage de la machine.Inside the washing tub is mounted in known manner a drum 14, rotatable about an axis X during the various cycles of washing, rinsing and spinning of the machine.

Le tambour 14 est ici monté en rotation autour d'un axe horizontal X.The drum 14 is here mounted in rotation about a horizontal axis X.

On notera que la figure 2 est schématique et que de nombreux organes nécessaires au fonctionnement de la machine (et par exemple moteur, pompes, filtres, ...) ont été omis et n'ont pas besoin d'être décrits en détail ici.Note that Figure 2 is schematic and that many organs necessary for the operation of the machine (and for example engine, pumps, filters, ...) have been omitted and do not need to be described in detail here.

Afin de permettre l'introduction et le retrait du linge à l'intérieur du tambour rotatif 14, celui-ci comporte de manière connue une porte d'accès 14a, par exemple formée de deux vantaux 14a montés en pivotement sur la virole du tambour 14.In order to allow the introduction and removal of the laundry inside the rotary drum 14, it comprises in known manner an access door 14a, for example formed of two leaves 14a pivotally mounted on the shell of the drum 14 .

De manière similaire, la cuve de lavage 13 comporte également une porte de cuve 15 dont la structure et le fonctionnement seront décrits en détail ultérieurement.Similarly, the washing tank 13 also comprises a tank door 15 whose structure and operation will be described in detail later.

Cette porte de cuve permet d'obturer une ouverture 13a réalisée dans la cuve et disposée sensiblement au droit de l'ouverture d'accès 11a de la carrosserie 11 de la machine 10.This tank door makes it possible to close an opening 13a made in the tank and disposed substantially in line with the access opening 11a of the bodywork 11 of the machine 10.

Cette porte de cuve 15 peut ainsi être mobile entre une position fermée dans laquelle elle obture l'ouverture 13a, de manière étanche, et une position ouverte dans laquelle le vantail 15 de porte de cuve est disposé entre la paroi de la cuve 13 et la carrosserie 11 de la machine 10.This tank door 15 can thus be movable between a closed position in which it closes the opening 13a in a sealed manner and an open position in which the door leaf 15 is disposed between the wall of the tank 13 and the body 11 of the machine 10.

Cette position ouverte de vantail 15 est notamment illustrée à la figure 2.This open leaf position 15 is particularly illustrated in FIG. 2.

On a illustré de manière isolée sur la figure 1 la cuve 13 conforme à l'invention équipée d'un système de porte de cuve.The tank 13 according to the invention equipped with a tank door system is illustrated in isolation in FIG.

La cuve 13 dans cet exemple a une paroi cylindrique, virole 16, de telle sorte que le vantail 15 de la porte est également constitué d'une portion de cylindre adaptée à obturer une ouverture 13a de la virole 16The tank 13 in this example has a cylindrical wall, ferrule 16, so that the leaf 15 of the door also consists of a cylinder portion adapted to close an opening 13a of the ferrule 16

Sur la figure 1, le vantail de la porte de cuve est illustré en position semi-ouverte, l'ouverture 13a de la cuve étant partiellement obturée.In Figure 1, the leaf of the tank door is illustrated in half-open position, the opening 13a of the tank being partially closed.

Ce vantail 15 est déplacé en coulissement grâce à des moyens d'actionnement.This leaf 15 is slidably displaced by means of actuation.

Les moyens d'actionnement 17 du vantail qui vont être décrits ultérieurement sont disposés principalement dans la partie basse de la cuve, et comme illustré à la figure 2, entre la cuve 13, la paroi de la carrosserie 11 et le fond de cette carrosserie.The actuating means 17 of the leaf which will be described later are arranged mainly in the lower part of the tank, and as shown in Figure 2, between the tank 13, the wall of the body 11 and the bottom of this body.

Comme bien illustré sur la figure 1, le système de porte de cuve comporte également des premiers moyens de guidage 18 disposés de part et d'autre de l'ouverture 13a de la cuve 13. Ces premiers moyens de guidage 18 sont adaptés à guider en coulissement un premier bord 15a du vantail 15.As is well illustrated in FIG. 1, the tank door system also comprises first guide means 18 arranged on either side of the opening 13a of the tank 13. These first guide means 18 are adapted to guide in sliding a first edge 15a of the leaf 15.

Comme bien illustré sur les figures 3 à 7, les premiers moyens de guidage 18 sont constitués d'un rail positionné en bordure de l'ouverture 13a.As well illustrated in Figures 3 to 7, the first guide means 18 consist of a rail positioned at the edge of the opening 13a.

Dans cet exemple où la cuve 13 est de forme cylindrique, les rails de guidage 18 sont adjacents au bord semi-circulaire 13b de l'ouverture 13a. Ces rails 18 ont eux-mêmes un profil longitudinal qui s'étend suivant une trajectoire tangente à la paroi 16 de la cuve 13. Dans cet exemple de réalisation, les rails de guidage s'étendent suivant une trajectoire sensiblement en arc de cercle, parallèle à la virole 16 de la cuve 13.In this example where the tank 13 is of cylindrical shape, the guide rails 18 are adjacent to the semicircular edge 13b of the opening 13a. These rails 18 themselves have a longitudinal profile which extends along a path tangent to the wall 16 of the vessel 13. In this embodiment, the guide rails extend in a substantially circular arc parallel path. to the shell 16 of the tank 13.

Pour permettre le guidage du vantail 15, ce dernier peut comporter au niveau du bord avant 15a, à chaque coin du vantail 15, des tétons (non représentés) adaptés à coulisser à l'intérieur du rail 18.To enable the guiding of the leaf 15, the latter may comprise at the front edge 15a, at each corner of the leaf 15, pins (not shown) adapted to slide inside the rail 18.

Plus précisément, dans ce mode de réalisation, et comme illustré les figures 3 à 7, le rail de guidage 18 comporte une portion principale, s'étendant en vis à vis de l'ouverture 13a de la cuve 13, déterminant une trajectoire en arc de cercle ayant un rayon de courbure sensiblement identique à celui de la cuve 13. Cette portion principale du rail de guidage 18 est prolongée au niveau d'une extrémité 18' par une portion de rail de guidage de rayon de courbure inversé permettant, lorsque le vantail 15 est en position extrême d'ouverture telle qu'illustrée à la figure 3, d'écarter quelque peu le bord 15a du vantail 15 de la paroi de la cuve 13.More specifically, in this embodiment, and as illustrated in FIGS. 3 to 7, the guide rail 18 comprises a main portion, extending opposite the opening 13a of the tank 13, determining an arcuate trajectory. of a circle having a radius of curvature substantially identical to that of the tank 13. This main portion of the guide rail 18 is extended at one end 18 'by a guide rail portion of inverted radius of curvature allowing, when the leaf 15 is in extreme open position as shown in Figure 3, to move somewhat aside the edge 15a of the leaf 15 of the wall of the tank 13.

Les moyens d'actionnement 17 sont dans ce mode de réalisation adaptés à agir sur un second bord 15b du vantail 15, opposé au premier bord 15a décrit précédemment.The actuating means 17 are in this embodiment adapted to act on a second edge 15b of the leaf 15, opposite the first edge 15a described above.

Ces moyens d'actionnement 17 comprennent tout d'abord un écrou 19 monté sur une vis 20 entraînée en rotation par un moteur 21.These actuating means 17 comprise first of all a nut 19 mounted on a screw 20 driven in rotation by a motor 21.

Ce moteur 21 peut être un moteur électrique classique.This motor 21 may be a conventional electric motor.

L'écrou 19 est immobilisé en rotation sur la vis 20 de telle sorte que la rotation de la vis provoque le coulissement de l'écrou 19 le long de cette vis 20.The nut 19 is immobilized in rotation on the screw 20 so that the rotation of the screw causes the nut 19 to slide along this screw 20.

Un levier 22 est monté en pivotement sur l'écrou 19. Une première extrémité 22a du levier 22 est fixée au second bord 15b du vantail 15. Une seconde extrémité 22b du levier 22 est montée en translation dans un rail de guidage 23 qui s'étend à proximité de la paroi 16 de la cuve 13.A lever 22 is pivotally mounted on the nut 19. A first end 22a of the lever 22 is fixed to the second edge 15b of the leaf 15. A second end 22b of the lever 22 is mounted in translation in a guide rail 23 which extends near the wall 16 of the tank 13.

En pratique, une plaque de support 24 est fixée sur la paroi 16, du côté extérieur de la cuve 13. Cette paroi 24 comporte des moyens classiques de fixation et de support du moteur 21.In practice, a support plate 24 is fixed on the wall 16, on the outside of the tank 13. This wall 24 comprises conventional means for fixing and supporting the motor 21.

La vis 20 est montée en rotation à une de ces extrémités sur un axe rotatif 21a du moteur.The screw 20 is rotatably mounted at one of these ends on a rotary shaft 21a of the engine.

A l'autre extrémité, la vis 20 est fixée également à l'extérieur de la cuve sur la paroi 16 par un palier 25 autorisant le mouvement de rotation de la vis 20.At the other end, the screw 20 is also fixed outside the tank on the wall 16 by a bearing 25 allowing the rotational movement of the screw 20.

Grâce au levier 22 et au rail de guidage 23, le second bord 15b du vantail 15 est guidé par ces moyens de guidage suivant une trajectoire qui s'étend à proximité de la paroi 16 de la cuve 13 lors du déplacement du vantail 15.Thanks to the lever 22 and the guide rail 23, the second edge 15b of the leaf 15 is guided by these guide means along a path that extends close to the wall 16 of the tank 13 during the movement of the leaf 15.

Plus particulièrement, le rail de guidage 23 dans lequel coulisse l'extrémité 22b du levier 22, est constitué d'une succession de portions de trajectoires différentes, s'étendant toutes principalement à proximité de la paroi 16 de la cuve 13.More particularly, the guide rail 23, in which the end 22b of the lever 22 slides, consists of a succession of portions of different trajectories, all of which extend mainly close to the wall 16 of the tank 13.

Ainsi, le rail de guidage 23 comporte une portion principale 23a s'étendant sur la majeure partie de la course du second bord 15b du vantail 15.Thus, the guide rail 23 has a main portion 23a extending over most of the stroke of the second edge 15b of the leaf 15.

Cette première portion principale 23a s'étend sensiblement parallèlement à la direction longitudinale de la vis 20.This first main portion 23a extends substantially parallel to the longitudinal direction of the screw 20.

A une première extrémité du rail de guidage 23, une seconde portion 23b s'étend perpendiculairement à la portion principale 23a. Cette seconde portion 23b du rail de guidage 23 correspond à une portion dans laquelle est guidée l'extrémité 22b du levier 22 lorsque le vantail 15 est en position ouverte telle qu'illustrée à la figure 3.At a first end of the guide rail 23, a second portion 23b extends perpendicularly to the main portion 23a. This second portion 23b of the guide rail 23 corresponds to a portion in which is guided the end 22b of the lever 22 when the leaf 15 is in the open position as illustrated in Figure 3.

Cette seconde portion 23b s'étend perpendiculairement à l'axe longitudinal de la vis 20, à l'opposé de celle-ci et à proximité de l'extrémité de cette vis 20 montée sur l'axe rotatif 21a du moteur 21.This second portion 23b extends perpendicularly to the longitudinal axis of the screw 20, opposite it and close to the end of this screw 20 mounted on the rotary shaft 21a of the motor 21.

Comme bien illustré sur la figure 3, grâce à cette disposition particulière de l'extrémité du rail de guidage 23, en bout de course d'ouverture du vantail 15, le levier 22 pivote autour de l'écrou mobile 19 de telle sorte que l'extrémité 22a du levier 22, à laquelle est fixé le second bord 15b du vantail 15, s'étend au-delà de l'extrémité de la vis 20, et dans ce mode de réalisation en dessous de celle-ci.As is well illustrated in FIG. 3, thanks to this particular arrangement of the end of the guide rail 23, at the opening end of the leaf 15, the lever 22 pivots around the movable nut 19 so that the 22a end of the lever 22, to which is fixed the second edge 15b of the leaf 15, extends beyond the end of the screw 20, and in this embodiment below it.

Ainsi, la course du vantail 15 est supérieure à la longueur de la vis 20.Thus, the travel of leaf 15 is greater than the length of screw 20.

La portion principale 23a du rail de guidage 23 comporte également une autre extrémité 23c, 23d, dans laquelle est guidée l'extrémité 22b du levier 22 lorsque le vantail est en position d'approche de fermeture telle qu'illustrée à la figure 5 et en position fermée telle qu'illustrée à la figure 5.The main portion 23a of the guide rail 23 also has another end 23c, 23d, in which is guided the end 22b of the lever 22 when the leaf is in the closed approach position as shown in Figure 5 and in FIG. closed position as shown in Figure 5.

Le rail de guidage comporte ainsi une troisième portion 23c, de courte dimension, s'étendant également perpendiculaire à la portion principale 23a du rail de guidage, et en direction de la vis 20. Cette troisième portion 23c du rail de guidage permet par l'intermédiaire du levier 22 de rapprocher le vantail 15 de l'ouverture 13a.The guide rail thus comprises a third portion 23c, of short dimension, also extending perpendicular to the main portion 23a of the guide rail, and in the direction of the screw 20. This third portion 23c of the guide rail allows by the intermediate lever 22 to bring the leaf 15 of the opening 13a.

Cette troisième portion 23c du rail de guidage 23 est ensuite prolongée par une portion rectiligne 23d parallèle à la direction longitudinale de la vis.This third portion 23c of the guide rail 23 is then extended by a rectilinear portion 23d parallel to the longitudinal direction of the screw.

Comme bien illustré sur les figures 5 et 6, cette quatrième portion 23d du rail de guidage permet, à proximité de la position de fermeture du vantail 15, de déplacer celui-ci, toujours sous l'action de la vis 20 entraînant l'écrou 19, dans un mouvement de va et vient en translation.As is well illustrated in FIGS. 5 and 6, this fourth portion 23d of the guide rail makes it possible, near the closing position of the leaf 15, to move it, again under the action of the screw 20 driving the nut. 19, in a movement back and forth in translation.

Comme cela sera décrit ultérieurement, des moyens de verrouillage, disposés au niveau du premier bord 15a du vantail 15 sont adaptés à être placés alternativement dans une position en prise et dans une position libérée lorsque le bord 15a du vantail 15 est déplacé suivant un mouvement de va et vient à proximité du côté 13c de l'ouverture 13.As will be described later, locking means, disposed at the first edge 15a of the leaf 15 are adapted to be placed alternately in an engaged position and in a released position when the edge 15a of the leaf 15 is moved in a movement of comes and goes near the 13c side of the opening 13.

Ainsi comme illustré sur les figures 5 et 6, lors de la fermeture du vantail 15, l'extrémité 22b du levier 22 est guidée jusqu'à l'extrémité terminale du rail de guidage 23, au niveau de la quatrième portion rectiligne 23d. Dans la position fermée telle qu'illustrée à la figure 6, les moyens d'actionnement sont adaptés à déplacer en sens inverse le second bord 15b du vantail 15 de telle sorte qu'en position fermée, l'extrémité 22b du levier est située en amont de l'extrémité terminale du rail de guidage 23, et dans cet exemple de réalisation, sensiblement au niveau de la jonction de la troisième portion 23c et de la quatrième portion 23d du rail de guidage.Thus, as illustrated in FIGS. 5 and 6, during closing of leaf 15, end 22b of lever 22 is guided to the end end of guide rail 23, at the level of fourth rectilinear portion 23d. In the closed position as illustrated in FIG. 6, the actuating means are adapted to move the second edge 15b of the leaf 15 in opposite directions so that, in the closed position, the end 22b of the lever is located in upstream of the end end of the guide rail 23, and in this embodiment, substantially at the junction of the third portion 23c and the fourth portion 23d of the guide rail.

On va décrire à présent en référence aux figures 7A et suivantes les moyens de verrouillage du premier bord 15a du vantail 15 sur la virole 16, au niveau du bord d'ouverture 13c.We will now describe with reference to Figures 7A and following the locking means of the first edge 15a of the leaf 15 on the shell 16, at the opening edge 13c.

Ce système de verrouillage permet de verrouiller et déverrouiller la fermeture du vantail 15 par un simple mouvement en va et vient du vantail 15.This locking system makes it possible to lock and unlock the closure of the leaf 15 by a simple movement back and forth of the leaf 15.

Il met en oeuvre une came-coeur utilisée classiquement dans des stylos billes à mine rétractable ou encore des boites à gants....It uses a cam-heart conventionally used in retractable ballpoint pens or glove boxes.

Un tel système de came est disposé sur les deux côtés du premier bord 15a du vantail de manière à permettre le verrouillage et le déverrouillage du vantail au deux coins de l'ouverture 13a de la cuve13.Such a cam system is disposed on both sides of the first edge 15a of the leaf so as to allow the locking and unlocking of the leaf at the two corners of the opening 13a of the tank13.

On va décrire ci-après le fonctionnement d'une came-coeur équipant l'un des côtés du vantail 15, étant entendu que l'autre côté est identique.We will describe below the operation of a cam-heart equipping one side of the leaf 15, it being understood that the other side is identical.

Comme bien illustré sur la figure 8B, le système de verrouillage de la porte de cuve 15 comporte un crochet mâle 30 solidaire du premier bord 15a du vantail 15 et adapté à coopérer avec un crochet femelle 31 fixé sur la virole 16 de la cuve, à proximité du bord d'ouverture 13c.As well illustrated in FIG. 8B, the locking system of the tank door 15 comprises a male hook 30 secured to the first edge 15a of the leaf 15 and adapted to cooperate with a female hook 31 fixed on the shell 16 of the tank, to near the opening edge 13c.

La came coeur comporte une navette 32 solidaire d'un bras rigide 33 pourvu d'un doigt 34. Ce doigt 34 est adapté à coopérer avec le profil particulier de la came-coeur 35 et d'une rampe 36. La navette 32 comporte une rampe 32a, sur laquelle peut coulisser le crochet mâle 30, et un logement 32b adapté à coopérer avec une saillie 30a du crochet pour bloquer le mouvement du crochet mâle 30 sur la rampe 32a de la navette 32.The core cam comprises a shuttle 32 secured to a rigid arm 33 provided with a finger 34. This finger 34 is adapted to cooperate with the particular profile of the cam-core 35 and a ramp 36. The shuttle 32 comprises a ramp 32a, on which can slide the male hook 30, and a housing 32b adapted to cooperate with a projection 30a of the hook to block the movement of the male hook 30 on the ramp 32a of the shuttle 32.

La navette 32 est montée en coulissement sur la virole 16. Une partie d'arrêt 37 permet de limiter le mouvement de la navette 32 dans un sens de translation.The shuttle 32 is slidably mounted on the shell 16. A stop portion 37 limits the movement of the shuttle 32 in a translation direction.

Un ressort 38 est disposé entre un plot de guidage 39, solidaire de la virole 16, et un logement 40 dans lequel peut coulisser une extrémité du bras 33.A spring 38 is disposed between a guide stud 39, integral with the ferrule 16, and a housing 40 in which one end of the arm 33 can slide.

Le plot de guidage 39 coopère avec une gorge rectiligne 41 ménagée dans la navette 32 pour le guidage en translation de la navette 32 sur la virole 16.The guide stud 39 cooperates with a rectilinear groove 41 formed in the shuttle 32 for translational guidance of the shuttle 32 on the ferrule 16.

Le ressort 38 peut être comprimé par le bras 33 lorsque la navette 32 est déplacée en direction de la partie d'arrêt 37. Cette position correspond à une position instable de la navette 32, du fait de la force de rappel exercée par le ressort 38.The spring 38 can be compressed by the arm 33 when the shuttle 32 is moved towards the stop portion 37. This position corresponds to an unstable position of the shuttle 32, due to the restoring force exerted by the spring 38 .

On va décrire à présent le procédé de fermeture et de verrouillage d'une porte de cuve de machine à laver telle que décrite précédemment.We will now describe the method of closing and locking a washing machine tank door as described above.

En pratique, la fermeture de cette porte 15 de cuve est mise en oeuvre après détection d'un début de cycle de lavage.In practice, the closing of this tank door 15 is carried out after detection of a start of a washing cycle.

Les machines à laver sont généralement équipées d'un système de détection de début et de fin d'un cycle de lavage, permettant de verrouiller la porte d'accès 12 de la carrosserie 11 de la machine pendant tout le cycle de lavage.The washing machines are generally equipped with a detection system at the beginning and the end of a washing cycle, making it possible to lock the access door 12 of the bodywork 11 of the machine during the entire washing cycle.

La détection du début d'un cycle de lavage est ainsi effectivement mise en oeuvre lorsque l'utilisateur actionne un bouton de démarrage d'un programme de lavage (et/ou éventuellement de séchage) et commande alors le verrouillage de la porte d'accès.The detection of the beginning of a washing cycle is thus effectively implemented when the user actuates a start button of a washing program (and / or possibly drying) and then controls the locking of the access door. .

lci, ce signal de détection commande également automatiquement la mise en route du moteur 21 de manière à déplacer le vantail 15 jusqu'à une position fermée, à partir de la position ouverte illustrée à la figure 3.Here, this detection signal also automatically controls the starting of the motor 21 so as to move the leaf 15 to a closed position, from the open position illustrated in FIG.

Comme décrit précédemment, le vantail 15 est déplacé suivant une trajectoire sensiblement tangente à la paroi de la cuve grâce au guidage du premier bord 15a dans les rails de guidage 18 et au guidage du second bord 15b du vantail 15 par l'intermédiaire du levier 22 et du rail de guidage 23. La position du vantail 15 pendant la fermeture est illustrée à la figure 4.As described above, the leaf 15 is moved along a path substantially tangent to the wall of the tank by guiding the first edge 15a in the guide rails 18 and guiding the second edge 15b of the leaf 15 via the lever 22 and the guide rail 23. The position of the leaf 15 during closing is illustrated in FIG. 4.

A l'approche de la position fermée telle qu'illustrée à la figure 5, le vantail 15 se trouve dans une position haute par rapport à la virole 16 de la cuve 13. Cette position haute est également illustrée à la figure 7B.Approaching the closed position as shown in Figure 5, the leaf 15 is in a high position relative to the ferrule 16 of the tank 13. This high position is also illustrated in Figure 7B.

Du fait de la poussée du vantail 15 contre la navette 32, cette dernière est déplacée sur le vantail 16 jusqu'à une position illustrée aux figures 9A et 9B, dans laquelle la navette 32 vient en butée sur la partie d'arrêt 37 solidaire de la virole 16.Due to the thrust of the leaf 15 against the shuttle 32, the latter is moved on the leaf 16 to a position shown in FIGS. 9A and 9B, in which the shuttle 32 abuts the stop portion 37 integral with the ferrule 16.

Du fait du déplacement de la navette 32, le bras 23 et le doigt 34 sont entraînés en coulissement de la position illustrée à la figure 7A jusqu'à la position illustrée à la figure 9A. En pratique, le doigt 34 est contraint à coulisser sur la portion 35α de la came 35 puis sur la rampe 36.Due to the displacement of the shuttle 32, the arm 23 and the finger 34 are slidably driven from the position shown in FIG. 7A to the position shown in FIG. 9A. In practice, the finger 34 is forced to slide on the portion 35 α of the cam 35 and then on the ramp 36.

Lorsque la navette 32 vient en butée, le doigt 34 est positionné sur l'extrémité de la rampe 36. La détection de la fin de course de la navette 32 est réalisée grâce à une électronique de commande détectant l'élévation du couple au niveau du moteur 21 ou par l'activation d'un switch placé en fin de course sur la partie d'arrêt 37, permettant de détecter la position de la navette 32 en butée contre cette partie d'arrêt 37.When the shuttle 32 comes into abutment, the finger 34 is positioned on the end of the ramp 36. The detection of the end of travel of the shuttle 32 is performed by means of a control electronics detecting the rise in the torque at the 21 or by the activation of a switch placed at the end of the stroke on the stop portion 37, for detecting the position of the shuttle 32 abuts against this stop portion 37.

Cette position n'est que transitoire du fait de la présence du ressort 38 disposé entre le plot de guidage 39 et le bras 33. Sous l'action de rappel du ressort 38, le doigt 34 coulisse en sens inverse sur la rampe 36. Du fait de la raideur du bras 33, le doigt 34 vient en butée dans un logement 35β de la came 35 telle qu'illustrée à la figure 8A.This position is only transient because of the presence of the spring 38 disposed between the guide pin 39 and the arm 33. Under the spring return action 38, the finger 34 slides in the opposite direction on the ramp 36. Due to the stiffness of the arm 33, the finger 34 comes into abutment in a recess 35 of the β cam 35 as illustrated in Figure 8A.

Simultanément, la détection de la fin de course du vantail 15 commande l'inversion du sens de rotation du moteur 21 de telle sorte que le vantail 15 passe de la position en approche de fermeture illustrée à la figure 5 jusqu'à la position fermée illustrée à la figure 6.Simultaneously, the detection of the end of travel of the leaf controls the reversal of the direction of rotation of the motor 21 so that the leaf passes from the closed approach position illustrated in FIG. 5 to the illustrated closed position. in Figure 6.

Lors de ce mouvement, le levier 22 est guidé par son extrémité 22b dans la quatrième portion 23d du rail de guidage 23.During this movement, the lever 22 is guided by its end 22b in the fourth portion 23d of the guide rail 23.

L'espace libéré par la navette 32 permet au crochet 30 de venir en prise avec le crochet femelle 31 sous la pression en outre de lames ressorts non représentées. Cette position correspond à la position fermée et verrouillée de la porte de cuve.The space released by the shuttle 32 allows the hook 30 to engage with the female hook 31 under the pressure further leaf springs not shown. This position corresponds to the closed and locked position of the tank door.

On notera en particulier la présence de joints d'étanchéité 42 tels qu'illustrés à la figure 6 permettant de garantir l'étanchéité par un contact entre le vantail 15 et la virole 16 de la cuve 13.It will be noted in particular the presence of seals 42 as illustrated in Figure 6 to ensure sealing by contact between the leaf 15 and the shell 16 of the tank 13.

La porte 15 est ainsi plaquée contre la cuve. Dès lors que le crochet mâle 30 vient en prise avec le crochet femelle 31 solidaire de la virole, le vantail 15 ne peut plus coulisser. L'action du moteur 21 sur la vis 20, transmise à l'écrou 19 a pour effet d'exercer une force de traction sur le second bord 15b du vantail 15. L'élévation du couple moteur plaque ainsi la porte 15 contre la cuve.The door 15 is thus pressed against the tank. As soon as the male hook 30 comes into engagement with the female hook 31 secured to the shell, the leaf 15 can not slide anymore. The action of the motor 21 on the screw 20, transmitted to the nut 19 has the effect of exerting a traction force on the second edge 15b of the leaf 15. The elevation of the engine torque thus plates the door 15 against the tank .

Le cycle de lavage peut alors commencer.The wash cycle can then begin.

On va décrire à présent un procédé d'ouverture d'une porte de cuve conforme à l'invention.We will now describe a method of opening a tank door according to the invention.

Cette ouverture est mise en oeuvre après détection d'une fin de cycle de lavage. Ce type de détection est mis en oeuvre classiquement dans une machine pour autoriser l'ouverture de la porte d'accès 12 de la carrosserie 11 à la fin d'un cycle de lavage.This opening is carried out after detection of an end of washing cycle. This type of detection is conventionally implemented in a machine to authorize the opening of the access door 12 of the bodywork 11 at the end of a washing cycle.

L'ouverture de la porte de cuve est de préférence mise en oeuvre avant même le déverrouillage de la porte d'accès 12, de telle sorte que cette porte de cuve sera ouverte lorsque l'utilisateur aura accès à la machine. On garantit ainsi l'invisibilité de cette porte de cuve pour l'utilisateur.The opening of the tank door is preferably implemented even before the unlocking of the access door 12, so that the tank door will be open when the user will have access to the machine. This guarantees the invisibility of this tank door for the user.

Lors de l'ouverture de la porte de cuve 15, le moteur 21 et la vis 20 entraîne tout d'abord l'écrou 19, le levier 22 et le vantail 15 vers le haut.When opening the tank door 15, the motor 21 and the screw 20 first drives the nut 19, the lever 22 and the leaf 15 upwards.

Ainsi, le crochet 30 est extrait du crochet femelle 31 et est poussé sur la rampe 32a de la navette 32 telle qu'illustrée sur les figures 9A et 9B jusqu'au blocage de la saillie 30a du crochet mâle 30 dans le logement 32a de la navette 32. La poussée du vantail 15 est alors transmise à la navette 32 jusqu'à sa position en butée contre l'élément d'appui 37. Lors du déplacement de la navette 32, le bras 33 entraîne également en coulissement le doigt 34 sur une portion 35γ de la came 35 jusqu'à l'extrémité de cette came 35, telle qu'illustrée dans la position de la figure 9A.Thus, the hook 30 is extracted from the female hook 31 and is pushed onto the ramp 32a of the shuttle 32 as illustrated in FIGS. 9A and 9B until the protrusion 30a of the male hook 30 is locked in the housing 32a of the shuttle 32. The thrust of the leaf 15 is then transmitted to the shuttle 32 to its position in abutment against the support element 37. During the displacement of the shuttle 32, the arm 33 also slidably drives the finger 34 on a portion 35γ of the cam 35 to the end of this cam 35, as shown in the position of Figure 9A.

Du fait de la force de rappel exercée par le ressort 38, la navette 32 est ramenée dans sa position initiale telle qu'illustrée à la figure 7A, le premier bord 15a du vantail 1 étant maintenu en position haute par rapport à l'ouverture, au-dessus du crochet femelle 31, grâce à la navette 32 coopérant avec le crochet mâle 30.Due to the restoring force exerted by the spring 38, the shuttle 32 is brought back to its initial position as illustrated in FIG. 7A, the first edge 15a of the leaf 1 being held in the up position with respect to the opening, above the female hook 31, thanks to the shuttle 32 cooperating with the male hook 30.

Le doigt 34 coulisse alors sur une quatrième portion 35γ de la came 35 pour revenir à la position d'équilibre de la figure 7A.The finger 34 then slides on a fourth portion 35γ of the cam 35 to return to the equilibrium position of Figure 7A.

Simultanément, la détection de fin de course de la navette 32 provoque l'inversion du sens de rotation du moteur 21 et de la vis 20.Simultaneously, the end-of-travel detection of shuttle 32 causes the reversal of the direction of rotation of motor 21 and screw 20.

Le vantail 15 est alors entraîné de sa position haute telle qu'illustrée à la figure 5 jusqu'à sa position ouverte telle qu'illustrée à la figure 3.Leaf 15 is then driven from its upper position as illustrated in FIG. 5 to its open position as illustrated in FIG.

Grâce à l'invention, on obtient ainsi un système de fermeture et d'ouverture de porte de cuve coulissante permettant de manière automatique d'obtenir la fermeture et le verrouillage de la porte 15 en début de cycle de lavage, puis le déverrouillage et l'ouverture de la porte 15 de la cuve 13 à la fin d'un cycle de lavage.Thanks to the invention, a closing and opening system of a sliding tank door is thus obtained, which automatically enables closing and locking of the door 15 at the beginning of the washing cycle, then unlocking and unlocking. opening the door 15 of the tank 13 at the end of a washing cycle.

Ainsi, cette porte de cuve peut être fermée et ouverte sans requérir de manipulation de la part de l'utilisateur.Thus, this tank door can be closed and opened without requiring manipulation on the part of the user.

En outre, grâce aux moyens classiques de détection permettant de verrouiller la porte d'accès 12 de la carrosserie, l'ouverture et la fermeture de la porte de cuve peuvent être réalisées tant que la porte d'accès 12 de la carrosserie 11 est fermée, de telle sorte que l'utilisateur n'a pas accès à cette porte de cuve et que ses mouvements sont invisibles pour l'utilisateur.In addition, by conventional detection means for locking the access door 12 of the body, the opening and closing of the tank door can be performed as the access door 12 of the body 11 is closed , so that the user does not have access to this tank door and that his movements are invisible to the user.

Bien entendu, la présente invention n'est pas limitée aux exemples de réalisation décrits précédemment.Of course, the present invention is not limited to the embodiments described above.

En particulier, le système de verrouillage mettant en oeuvre une came coeur pourrait être remplacé par d'autres types de came permettant d'obtenir le verrouillage et le déverrouillage automatique de la porte 15 de la cuve.In particular, the locking system implementing a core cam could be replaced by other types of cam for obtaining the automatic locking and unlocking of the door 15 of the tank.

En outre, les deux systèmes de crochets 30, 31 disposés aux deux coins du vantail 15a peuvent être remplacés par un système de crochet unique associé à une came-coeur et disposé au milieu du premier bord 15a du vantail 15.In addition, the two hook systems 30, 31 arranged at the two corners of the leaf 15a can be replaced by a single hook system associated with a cam-heart and disposed in the middle of the first edge 15a of the leaf 15.
