Description

La présente invention concerne une machine à laver et/ou sécher le linge à tambour fermé par un portillon.The present invention relates to a washing machine and / or dryer laundry drum closed by a door.

Des machines à laver ou des machines à sécher le linge connues comprennent habituellement une porte et un système de sécurité comportant un microcontact monté dans un rebord de l'ouverture de ces machines et un doigt d'enclenchement fixé sur cette porte de manière à actionner ce microcontact lorsque celle-ci est en position de fermeture et permettre ainsi une mise en marche de ces machines par un commutateur marche-arrêt.Known washing machines or clothes drying machines usually include a door and a security system comprising a microswitch mounted in a flange of the opening of these machines and a latching finger fixed on this door so as to actuate it. microswitch when the latter is in the closed position and thus allow these machines to be started by an on-off switch.

Quand cette porte est ouverte le doigt d'enclenchement est retiré et le microcontact du système de sécurité est ouvert ce qui rend impossible une mise en marche de ces machines par le commutateur marche-arrêt.When this door is open, the latching finger is removed and the microswitch of the security system is open, which makes it impossible to start these machines with the on-off switch.

Dans les cuves de ces machines connues, leur tambour est fermé par un portillon pivotant ou coulissant qui est bloqué dans sa position de fermeture par un système de verrouillage. Dans certaines de ces machines connues, le portillon de leur tambour à linge a une double fonction, celle de fermeture et d'ouverture du trou d'accès dans ce tambour, et celle d'interdiction de rotation de ce tambour par accrochage de ses battant(s) et/ou système de verrouillage aux rebords du trou d'entrée de la cuve de ces machines durant l'ouverture de ce portillon. Cependant dans la plupart de ces machines connues, le contrôle de la fermeture du portillon du tambour à linge est souvent simplement visuel, et le système de sécurité de la machine a pour principal rôle d'arrêter la rotation du tambour à linge dès l'ouverture de la porte de ces machines, mais n'empêche pas une mise en marche de ces machines par le commutateur marche-arrêt lorsque le portillon de leur tambour à linge reste ouvert. Autrement dit dès la fermeture de la porte de ces machines connues quelle que soit son origine volontaire, accidentelle ou par inattention, une mise en marche de ces machines peut être effectuée même si le portillon de leur tambour est ouvert, ce qui provoque dans ce dernier cas soit une rupture de ce portillon ou des dégats dans celui-ci soit des dommages électriques et/ou mécaniques dans le système d'entraînement de ce tambour. Par ailleurs un grand nombre de ces machines connues ont des tambours à linge munis de portillons présentant des structures compliquées et onéreuses.In the tanks of these known machines, their drum is closed by a pivoting or sliding door which is locked in its closed position by a locking system. In some of these known machines, the gate of their laundry drum has a double function, that of closing and opening the access hole in this drum, and that of prohibiting rotation of this drum by hooking its wings (s) and / or locking system at the edges of the inlet hole of the tank of these machines during the opening of this door. However in most of these known machines, the control of the closing of the door of the laundry drum is often simply visual, and the safety system of the machine has the main role of stopping the rotation of the laundry drum upon opening. the door of these machines, but does not prevent these machines from being started by the on-off switch when the door of their drum laundry remains open. In other words, as soon as the door of these known machines is closed, whatever its voluntary, accidental or inadvertent origin, these machines can be started even if the door of their drum is open, which in turn causes the latter either a rupture of this gate or damage to it or electrical and / or mechanical damage in the drive system of this drum. Furthermore, a large number of these known machines have laundry drums provided with gates having complicated and expensive structures.

La présente invention ayant pour but d'éviter ces inconvénients, permet de réaliser une machine à laver et/ou sécher le linge à tambour économique, efficace en sécurité de fonctionnement dans laquelle le tambour à linge est pourvu d'un portillon et d'un système de verrouillage présentant une structure solide, simple, comportant peu d'éléments faciles à fabriquer à monter et à fonctionner.The aim of the present invention is to avoid these drawbacks and makes it possible to produce an economical washing machine and / or dryer for laundry with a drum, effective in operating safety in which the laundry drum is provided with a door and a locking system with a solid, simple structure, comprising few elements which are easy to manufacture, to assemble and operate.

Selon l'invention, une machine à laver et/ou sécher le linge à tambour fermé par un portillon bloqué en position de fermeture par un système de verrouillage, est caractérisée en ce que dans le tambour à linge, le portillon assure, selon ses positions, deux fonctions, celle de fermeture de l'ouverture de ce tambour lorsqu'il est en position de fermeture, et celle d'interdiction de rotation du tambour d'avant en arrière lorsqu'il est en position d'ouverture, et le système de verrouillage de ce portillon assure, selon ses positions, trois fonctions, celle de blocage en fermeture du portillon lorsqu'il est en position de fermeture, celle d'interdiction de rotation du tambour à linge d'arrière en avant et celle d'interdiction de mise en marche du sèche-linge lorsqu'il est en position d'ouverture.According to the invention, a machine for washing and / or drying linen with a drum closed by a gate blocked in the closed position by a locking system, is characterized in that in the laundry drum, the gate ensures, according to its positions , two functions, that of closing the opening of this drum when it is in the closed position, and that of preventing rotation of the drum back and forth when it is in the open position, and the system according to its positions, the locking mechanism of this gate provides three functions, that of locking the gate when it is closed when it is in the closed position, that of preventing the tumble drum from rotating from back to front and that of prohibiting the dryer when it is in the open position.

L'invention est applicable à une machine à tambour telle qu'un lave-linge, un lavant séchant et un sèche-linge.The invention is applicable to a drum machine such as a washing machine, a washer-dryer and a dryer.

Dans un but de simplification de la description un sèche-linge réalisé selon l'invention est seul décrit ci-après.In order to simplify the description, only a dryer produced according to the invention is described below.

Un sèche-linge 1 schématiquement et partiellement illustré dans la figure 1, comprend une carrosserie 2 munie dans un dessus 3 d'une ouverture 4 fermée par une porte 5 de l'appareil. Le sèche-linge 1 comprend dans son enceinte un tambour à linge 6 tournant autour d'un axe horizontal et muni, dans sa paroi latérale cylindrique, d'une ouverture 9 fermée par un portillon à un seul battant 7 qui, par recouvrement s'appuie en sa position de fermeture sur la bordure de cette ouverture 9 et épouse la surface cylindrique du tambour 6. Le portillon 7 est monté par son bord arrière sur le bord arrière de cette ouverture 9 du tambour 6, pivotant autour d'un axe horizontal 8, muni de ressorts 10 et 11 qui le rappellent constamment dans sa position ouverte. Le portillon 7 est bloqué dans sa position de fermeture (figures 3 et 4) par un système de verrouillage 15.A dryer 1 schematically and partially illustrated in Figure 1, comprises a body 2 provided in a top 3 with an opening 4 closed by a door 5 of the device. The dryer 1 comprises in its enclosure a laundry drum 6 rotating around a horizontal axis and provided, in its cylindrical side wall, with an opening 9 closed by a single-leaf door 7 which, by covering is presses in its closed position on the edge of this opening 9 and follows the cylindrical surface of the drum 6. The gate 7 is mounted by its rear edge on the rear edge of this opening 9 of the drum 6, pivoting about a horizontal axis 8, provided with springs 10 and 11 which constantly remind it in its open position. The gate 7 is locked in its closed position (FIGS. 3 and 4) by a locking system 15.

Selon une caractéristique importante de l'invention dans le tambour à linge 6 du sèche-linge 1, le portillon 7 assure, selon ses positions, deux fonctions, celle de fermeture de l'ouverture 9 de ce tambour à linge 6, lorsqu'il est en position de fermeture (figures 3 et 4) et celle d'interdiction de rotation du tambour 6 d'avant en arrière lorsqu'il est en position d'ouverture, et le système de verrouillage 15 assure selon ses positions, trois fonctions, celle de blocage en fermeture du portillon 7 lorsqu'il est en position de fermeture (figures 3 et 4), celle d'interdiction de rotation du tambour 6 d'arrière en avant et celle d'interdiction de mise en marche du sèche-linge 1 lorsqu'il est en position d'ouverture.According to an important characteristic of the invention in the laundry drum 6 of the dryer 1, the door 7 provides, according to its positions, two functions, that of closing the opening 9 of this laundry drum 6, when is in the closed position (FIGS. 3 and 4) and that for preventing the drum 6 from rotating back and forth when it is in the open position, and the locking system 15 provides three functions, depending on its positions, that of blocking the gate 7 when it is in the closed position (FIGS. 3 and 4), that of prohibiting rotation of the drum 6 from back to front and that of prohibiting starting the dryer 1 when in the open position.

Selon une autre caractéristique, le portillon 7 comprend dans sa partie frontale une dépression ou creux 12 munie d'au moins un ergot de retenue saillant destiné à coopérer avec le système de verrouillage 15 pour bloquer le portillon 7 lorsque ce dernier est en position de fermeture.According to another characteristic, the gate 7 comprises in its front part a depression or hollow 12 provided with at least one projecting retaining lug intended to cooperate with the locking system 15 to block the gate 7 when the latter is in the closed position .

Dans l'exemple illustré à la figure 2, le portillon 7 comprend dans sa dépression frontale 12, deux ergots latéraux de retenue saillants vers l'avant 13,14.In the example illustrated in FIG. 2, the door 7 comprises in its front depression 12, two lateral retaining lugs projecting forward 13,14.

Selon une autre caractéristique, dans le sèche-linge 1, le système de verrouillage du portillon 7 du tambour à linge 6 est constitué par un levier-poignée 15 dont l'extrémité du côté du levier est montée sur le bord frontal de l'ouverture 9 de ce tambour 6, pivotante autour d'un axe horizontal 16 et munie de ressorts 17, 18 qui rappellent constamment le levier-poignée dans sa position de déverrouillage et dont l'extrémité du côté de la poignée est libre et munie d'un volet 19 servant de poignée, articulable suivant un angle prédéterminée réduit autour d'un axe horizontal 20, et constamment rappelé, par des ressorts non représentés, contre des butées 21,22 formées dans ce levier-poignée 15.According to another characteristic, in the dryer 1, the locking system of the door 7 of the laundry drum 6 is constituted by a lever-handle 15, the end of the side of the lever is mounted on the front edge of the opening 9 of this drum 6, pivoting about a horizontal axis 16 and provided with springs 17, 18 which constantly remind the lever-handle in its unlocked position and whose end on the side of the handle is free and provided with a flap 19 serving as a handle, articulated at a predetermined angle reduced around a horizontal axis 20, and constantly recalled, by springs not shown, against stops 21, 22 formed in this lever-handle 15.

Le sèche-linge 1 comprend un système de sécurité de fonctionnement comportant d'une part un microcontact de sécurité de mise en marche 26, monté en série dans le circuit électrique du sèche-linge 1 et fixé dans le dessus 3, en alignement avec un trou d'accès 24 formé dans un rebord de l'ouverture 4 et d'autre part un doigt d'enclenchement 25 fixé dans un bord de la porte 5 du sèche-linge 1 de manière soit à pénétrer dans ce trou d'accès 24 lors d'une fermeture de la porte 5, pour actionner le microcontact de sécurité 26, le mettre en position d'enfoncement et établir en conséquence une jonction dans ce circuit électrique du sèche-linge 1 et permettre ainsi une mise en marche du sèche-linge par un commutateur marche-arrêt non représenté soit à se dégager de ce trou d'accès 24 lors d'une ouverture de la porte 5, pour libérer le microcontact de sécurité 26, le mettre dans sa position de repos, créer une interruption dans le circuit électrique du sèche-linge 1, et empêcher ainsi toute mise en marche du sèche-linge 1 par le commutateur marche-arrêt.The dryer 1 includes a safety system operation comprising on the one hand a start-up safety microswitch 26, mounted in series in the electrical circuit of the dryer 1 and fixed in the top 3, in alignment with an access hole 24 formed in a flange of the opening 4 and on the other hand a locking finger 25 fixed in an edge of the door 5 of the dryer 1 so as either to enter this access hole 24 when the door 5 is closed, to activate the safety microswitch 26, put it in the insertion position and consequently establish a junction in this electrical circuit of the dryer 1 and thus allow the dryer to be started by an on-off switch not shown, either at disengage from this access hole 24 when the door 5 opens, to release the safety microswitch 26, put it in its rest position, create an interruption in the electrical circuit of the dryer 1, and prevent thus any activation of the dryer 1 by the market switch e-stop.

Dans sa position de déverrouillage (figure 1) le levier-poignée 15 s'appuie contre le rebord de l'ouverture 4 du dessus 3 du sèche-linge 1, cache par son volet ou poignée 19, le trou 24 d'accès au microcontact de sécurité 26 et empêche par conséquent le doigt d'enclenchement 25 de pénétrer dans ce trou d'accès 24 pour actionner ce microcontact 26, établir une jonction dans le circuit électrique du sèche-linge et permettre une mise en marche de l'appareil par le commutateur marche-arrêt.In its unlocking position (Figure 1) the lever-handle 15 is pressed against the edge of the top opening 4 of the dryer 1, hidden by its flap or handle 19, the hole 24 for access to the microswitch 26 and therefore prevents the locking finger 25 from entering this access hole 24 to activate this microswitch 26, establish a junction in the electrical circuit of the dryer and allow the appliance to be started by the on-off switch.

Dans l'exemple illustré (figure 1) le sèche-linge 1 comprend dans la zone du rebord de l'ouverture 4 du dessus 3 recouvrant le trou 24 d'accès au microcontact 26, un évidement ou creux 23 destiné à loger, par emboîtement de préférence à fleur de surface, le levier-poignée 15 qui constitue le système de verrouillage du portillon 7 du tambour à linge 6.In the example illustrated (FIG. 1) the dryer 1 comprises in the region of the rim of the opening 4 from above 3 covering the hole 24 for access to the microswitch 26, a recess or recess 23 intended to accommodate, by interlocking preferably flush with the surface, the lever-handle 15 which constitutes the locking system for the door 7 of the laundry drum 6.

Lors d'une fermeture du tambour à linge 6, le portillon 7, est d'abord pivoté autour de son axe 8 vers le bas et appliqué contre la bordure de l'ouverture 9 de ce tambour puis le levier-poignée 15 constituant le système de verrouillage est également pivoté autour de son axe 16 vers le bas jusqu'à ce qu'il pénètre dans la dépression frontale 12 du portillon 7 exerce une pression élastique sur ce dernier, et que son volet 19 s'enclenche sous les ergots de retenue 13,14 de ce portillon 7 pour le bloquer dans sa position de fermeture. La porte 5 peut alors être fermée et le doigt d'enclenchement 25 peut pénétrer dans le trou 24, actionner ce microcontact 26, établir une jonction dans le circuit électrique du sèche-linge et permettre une mise en marche de l'appareil par le commutateur marche-arrêt.When the laundry drum 6 is closed, the door 7 is first pivoted about its axis 8 downwards and applied against the edge of the opening 9 of this drum then the lever-handle 15 constituting the locking system is also pivoted about its axis 16 downwards until it enters the front depression 12 of the door 7 exerts an elastic pressure on the latter, and that its flap 19 snaps under the retaining pins 13,14 of this door 7 to lock it in its closed position. The door 5 can then be closed and the latching finger 25 can penetrate the hole 24, actuate this microswitch 26, establish a junction in the electrical circuit of the dryer and allow the appliance to be started by the switch On Off.

Durant le fonctionnement du sèche-linge 1, le linge tombe sur le portillon 7 et exerce sur celui-ci une force schématiquement représentée par une flèche F (figure 4) qui tend à l'ouvrir. Le portillon 7 transmet à son tour une force schématiquement représentée par une flèche F′ au système de verrouillage constitué par le levier-poignée 15, au niveau de leur zone de contact A qui est voisine de l'axe de pivotement 16 de ce levier-poignée 15. Plus cette force F est grande plus la poussée exercée par la force F′ sur le levier-poignée 15 et par conséquent sur son volet 19 contre les ergots de retenue 13 et 14 est importante et plus le verrouillage du portillon 7 par ce levier-poignée 15 est solide.During the operation of the dryer 1, the laundry falls on the door 7 and exerts on it a force schematically represented by an arrow F (Figure 4) which tends to open it. The gate 7 in turn transmits a force schematically represented by an arrow F ′ to the locking system constituted by the lever-handle 15, at their contact zone A which is close to the pivot axis 16 of this lever- handle 15. The greater this force F, the greater the thrust exerted by the force F ′ on the lever-handle 15 and consequently on its flap 19 against the retaining lugs 13 and 14 is greater and the more the locking of the gate 7 by this lever-handle 15 is solid.

Lors d'une ouverture du tambour à linge 6, le volet 19 du levier-poignée 15 dans son rôle d'une poignée qui, après un pivotement autour de son axe 20 vers l'avant, se dégage des ergots de retenue 13,14 du portillon 7 et quitte sa première fonction de blocage en fermeture du portillon 7, est automatiquement rappelé par des ressorts 17,18 dans sa position de déverrouillage (figure 1) où le levier-poignée 15 est librement logé dans l'évidement 23.When opening the laundry drum 6, the flap 19 of the handle lever 15 in its role as a handle which, after pivoting about its axis 20 forwards, emerges from the retaining pins 13,14 of the gate 7 and leaves its first locking function when closing the gate 7, is automatically returned by springs 17, 18 to its unlocking position (FIG. 1) where the lever-handle 15 is freely housed in the recess 23.

Dans cette position de déverrouillage, le levier-poignée 15 remplit d'une part sa deuxième fonction d'interdiction de rotation du tambour à linge 6 d'arrière en avant par son coincement contre le rebord frontal de l'ouverture 4 du dessus 3 et d'autre part sa troisième fonction d'interdiction de mise en marche du sèche-linge 9 par le commutateur marche-arrêt de l'appareil, en cachant par son volet 19 le trou 24 d'accès au microcontact 26 et empêchant ainsi le doigt d'enclenchement 25 de pénétrer dans le trou 24 et d'actionner ce microcontact 26 pour supprimer une interruption créée par ce dernier dans le circuit électrique du sèche-linge 1 et établir une jonction électrique dans ce circuit.In this unlocking position, the lever-handle 15 fulfills on the one hand its second function of prohibiting rotation of the laundry drum 6 from back to front by its wedging against the front edge of the opening 4 from above 3 and on the other hand its third function of prohibiting the operation of the dryer 9 by the on-off switch of the apparatus, by hiding by its flap 19 the hole 24 for access to the microswitch 26 and thus preventing the locking finger 25 from entering the hole 24 and actuating this microswitch 26 to remove an interruption created by the latter in the electrical circuit of the dryer 1 and establish an electrical junction in this circuit.

Pendant ce temps, le portillon 7 qui, débloqué par le retrait du levier-poignée 15, quitte sa première fonction de fermeture de l'ouverture 9 du tambour à linge 6, est automatiquement rappelé par ses ressorts 10 et 11 dans sa position d'ouverture où par son application contre le rebord arrière de l'ouverture 4 du dessus 3 du sèche-linge 1, et remplit sa deuxième fonction d'interdiction de rotation du tambour à linge 6 d'avant en arrière.Meanwhile, the gate 7 which, unlocked by the withdrawal of the lever-handle 15, leaves its first function of closing the opening 9 of the laundry drum 6, is automatically recalled by its springs 10 and 11 in its position opening where by its application against the rear edge of the opening 4 of the top 3 of the dryer 1, and fulfills its second function of prohibiting rotation of the washing drum 6 from front to back.

Dans le sèche-linge 1, la sécurité de fonctionnement est ainsi efficacement assurée. Lors d'une ouverture de la porte 5 du sèche-linge 1 le microcontact 26 crée une interruption dans le circuit électrique de l'appareil, ce qui rend impossible une mise en marche par inattention du sèche-linge 1 par le commutateur marche-arrêt et évite à l'utilisateur un accident corporel par son libre accès au tambour à linge. Si la porte 5 est refermée par inadvertance, l'utillisateur n'a plus accès au tambour à linge 6, et une mise en marche du sèche-linge 1 peut être effectuée sans provoquer d'accident corporel ou de dommages mécaniques au tambour à linge 6.In the dryer 1, operational safety is thus effectively ensured. When the door 5 of the dryer 1 is opened, the microswitch 26 creates an interruption in the electrical circuit of the appliance, which makes it impossible to start the dryer 1 by inattention by the on-off switch. and prevents the user from a bodily accident by his free access to the laundry drum. If door 5 is inadvertently closed, the user no longer has access to the laundry drum 6, and the dryer 1 can be started without causing a personal injury or mechanical damage to the laundry drum 6.

Lors d'une ouverture de la porte 5 du sèche-linge 1 suivie d'une ouverture du portillon 7 du tambour à linge 6, le microcontact 26 crée une interruption dans le circuit électrique de l'appareil et le levier-poignée 15 du système de verrouilage du portillon 7 cache par son volet 19 le trou 24 d'accès au microcontact 26, si la porte 5 du sèche-linge 1 est ramenée ou poussée par inadvertance vers sa position de fermeture, le doigt d'enclenchement 25 ne peut pas pénétrer dans le trou 24 caché par le volet 19 du levier-poignée 15 et actionner le microcontact 26 pour établir une jonction dans le circuit électrique du sèche-linge 1, et il est alors impossible de mettre en marche le sèche-linge 1 par le commutateur marche-arrêt autrement dit impossible de faire tourner le tambour à linge 6 ce qui évite tous dommages mécaniques causés à ce tambour à linge et des accidents corporels à l'utilisateur.When the door 5 of the dryer 1 is opened, followed by an opening of the door 7 of the laundry drum 6, the microswitch 26 creates an interruption in the electrical circuit of the appliance and the lever-handle 15 of the system. for locking the door 7 hides by its flap 19 the hole 24 for access to the microswitch 26, if the door 5 of the dryer 1 is inadvertently brought back or pushed towards its closed position, the locking finger 25 cannot enter the hidden hole 24 by the flap 19 of the lever-handle 15 and actuate the microswitch 26 to establish a junction in the electrical circuit of the dryer 1, and it is then impossible to start the dryer 1 by the on-off switch in other words impossible to rotate the laundry drum 6 which avoids all mechanical damage to this laundry drum and personal injury to the user.

Le portillon 7 du tambour à linge 6 et son système de verrouillage constitué par le levier-poignée 15 décrit ci-dessus qui ont ainsi une structure simple, comportant un nombre réduit d'éléments mécaniquement solides, faciles à fabriquer, à monter, économiques, contribuent non seulement à donner à la fabrication du sèche-linge 1 un prix économique mais également à assurer une grande sécurité dans le fonctionnement du sèche-linge 1.The door 7 of the laundry drum 6 and its locking system constituted by the lever-handle 15 described above which thus have a simple structure, comprising a reduced number of mechanically solid elements, easy to manufacture, to assemble, economical, contribute not only to giving the manufacture of the dryer 1 an economical price but also to ensuring high safety in the operation of the dryer 1.
