Abstract

A top-loading washing machine has a security device for the flap doors on the revolving wash drum, to prevent breakdown if the machine is started when the doors have been left open. The device comprises known elements, e.g. the flap doors, having springs which act upon the doors to keep them open, and hooks mounted on the lower door, and new elements, e.g. hooks mounted on the upper door (not used for closure, but to engage with the lower edge of the elastic tubing which forms the connection between the outer opening and the tub).

Description

La présente invention concerne un dispositif de sécurité pour la porte d'un tambour rotatif, utilisable plus particulierement mais non exclusivement dans une. machine à laver le linge à chargement par la partie supérieure. The present invention relates to a safety device for the door of a rotary drum, usable more particularly but not exclusively in one. top loading washing machine.

Dans les machines à laver de ce type, la surface Za tépale du tambour comprend une porte constituée de deux volets permettant l'introduction du linge à l'intérieur du tambour et l'extraction de ce linge. Ces volets tendent à etre placés en position d'ouverture par l'intermédiaire d'un jeu de ressorts adaptés aux articulations de ces volets. Pour fermer la porte constituée de ces volets (une fois le linge placé dans le tambour ou extrait de ce dernier), on exerce une pression sur le volet inférieur puis une pression sur le volet supérieur de la porte jusqu'd ce qu'une paire de crochets solidaires du volet inférieur viennent s'engager dans des trous rainurés ou Lumières allongées correspondants du volet supérieur.Quand on relache la pression exercée sur les volets, les ressorts précités entrent en action et tendent à ouvrir les deux volets, ce qui assure le maintien de la position d'accrochage. In washing machines of this type, the tepal surface Za of the drum comprises a door made up of two flaps allowing the insertion of the linen inside the drum and the extraction of this linen. These components tend to be placed in the open position by means of a set of springs adapted to the articulations of these components. To close the door made up of these shutters (once the laundry has been placed in the drum or removed from it), pressure is applied to the lower shutter then pressure is applied to the upper shutter of the door until a pair hooks secured to the lower flap engage in grooved holes or corresponding elongated lights of the upper flap. When the pressure exerted on the flaps is released, the aforementioned springs come into action and tend to open the two flaps, which ensures the maintenance of the hanging position.

Ce dispositif de fermeture présente l'inconvénient important que si, par omission , la porte du tambour est laissée ouverte et la machine est mise en marche, cet incident fortuit peut occasionner une panne très importante. This closing device has the significant drawback that if, by omission, the door of the drum is left open and the machine is started, this accidental incident can cause a very significant breakdown.

La présente invention a pour but de résoudre ce problème en procurant un dispositif de sécurité qui assure immédiatement le blocage mécanique du tambour si, par suite d'une né gligence de l'utilisateur, ce dernier met la machine en marche alors que la porte du tambour n'est pas correctement fermée, et ce quelque soit le sens de rotation du tambour à ce moment. The present invention aims to solve this problem by providing a safety device which immediately ensures the mechanical blocking of the drum if, as a result of negligence on the part of the user, the latter starts the machine while the door of the drum is not properly closed, regardless of the direction of rotation of the drum at this time.

Le dispositif de sécurité suivant l'invention est particulierement simple du fait qu'interviennent uniquement d'une part les crochets solidaires du volet inférieur de la porte et qui sont utilisés également pour la fermeture de ceZZe-ci, et un crochet incorporé au volet supérieur de la porte n'intervenant pas pour la fermeture de celle-ci, et d'autre part des bords saillants jouant le roule d'ancrages pour les crochets précités et qui sont constitués par le rebord inférieur du tube élastique ou soufflet reliant l'ouverture. supérieure de la cuve contenant le tambour rotatif à l'embouchure de la plaque supérieure de la machine par où est chargé et extrait le linge.  The safety device according to the invention is particularly simple in that only the hooks integral with the lower flap of the door and which are also used for closing thisZZe, and a hook incorporated in the upper flap, intervene only. of the door not intervening for the closing of the latter, and on the other hand of the projecting edges playing the roll of anchors for the aforementioned hooks and which are constituted by the lower edge of the elastic tube or bellows connecting the opening . upper part of the tank containing the rotary drum at the mouth of the upper plate of the machine through which the laundry is loaded and extracted.

On décrira ci-après, d titre d'exemple non Zimitatif, une forme d'exécution de La présente invention en référence au dessin annexé sur ZequeZ
- la figure 1 est une vue en coupe verticale et transver- sale schématique du tambour d'une machine a laver le Zinge,ce ce tambour étant représenté en position ouverte et immobile dans laquelle il se prete au chargement ou au déchargement du linge;
- la figure 2 est une vue en coupe verticale et transversale schématique illustrant la position tambour ouvert et blo- qué";;
Sur le dessin, on voit certains éléments connuss d'une machine a laver ZeZinge,à savoir une cuve 1 , un tambour rotatif 2 avec une porte constituée de deux volets, à savoir un volet inférieur 3 et un volet supérieur 4, un tube élastique ou soufflet 5, une plaque supérieure 6 du carter de la machine à laver.
An embodiment of the present invention will be described below, by way of non-limiting example, with reference to the attached drawing on ZequeZ.
- Figure 1 is a schematic vertical cross-sectional view of the drum of a Zinge washing machine, this drum being shown in the open and stationary position in which it is suitable for loading or unloading laundry;
- Figure 2 is a schematic vertical and cross sectional view illustrating the open and locked drum position ";;
In the drawing, we see certain known elements of a ZeZinge washing machine, namely a tank 1, a rotary drum 2 with a door consisting of two flaps, namely a lower flap 3 and an upper flap 4, an elastic tube or bellows 5, an upper plate 6 of the casing of the washing machine.

Les positions verticales qu'occupent les volets de porte 3 et 4 sur la figure 1 sont maintenues par des ressorts associés aux articulations de ces volets et dans cette position, ceux-ci donnent un accès total à l'intérieur du tambour 2. Le volet de porte inférieur 3 est soZidaire, à l'extérieur, de crochets 7 qui coopèrent avec des trous respectifs 8 percés dans le volet supérieur 4. Ce volet supérieur 4 porte également à l'extérieur des crochets 9 n'intervenant en rien dans la fermeture de la porte. The vertical positions occupied by the door flaps 3 and 4 in FIG. 1 are maintained by springs associated with the articulations of these flaps and in this position, these give total access to the interior of the drum 2. The flap of the lower door 3 is soZidary, on the outside, of hooks 7 which cooperate with respective holes 8 drilled in the upper flap 4. This upper flap 4 also carries on the outside of the hooks 9 which are not involved in the closure Door.

L'ouverture supérieure de la cuve 1 est rectangulaire et est adaptée au rebord inférieur 10 du tuyau ou soufflet 5 qui présente à l'intérieur un bord saillant lOe d'un coté et lob du côté opposé. The upper opening of the tank 1 is rectangular and is adapted to the lower rim 10 of the pipe or bellows 5 which has inside a projecting edge lOe on one side and lob on the opposite side.

D'après ce qui précèdes on voit que le dispositif de sécurité suivant l'invention est constitué d'une part d'éléments connus, à savoir les volets de porte 3 et 4 équipés des ressorts d'articulation correspondants, et les crochets 7 solidaires du volet inférieur 3, et d'autre part d'éléments nouveau=, à savoir les crochets 9 solidaires du volet supérieur 4 de la porte et le rebord inférieur 10 du tuyau ou soufflet 5 . Les crochets 7 ou 9viennent respectivement staggriper aux bords lOa et lOb du rebord inférieur 10 quand le tambour tourne, avec la porte ouverte, vers la gauche ou vers la droite. From the above it can be seen that the safety device according to the invention consists on the one hand of known elements, namely the door flaps 3 and 4 fitted with the corresponding articulation springs, and the hooks 7 secured of the lower flap 3, and on the other hand of new elements =, namely the hooks 9 integral with the upper flap 4 of the door and the lower flange 10 of the pipe or bellows 5. The hooks 7 or 9 are respectively staggriper at the edges 10a and 10b of the lower edge 10 when the drum turns, with the door open, to the left or to the right.

La position représentée sur la figure 2 correspond au blocage mécanique du tambour 2 Zorsque ce dernier tourne vers la gauche avec la porte ouverte. On peut observer que dans ce cas, les crochets 7 du volet inférieur 3 de la porte viennent s'aggriper sur le rebord saillant 10a. IZ est évident que L'arrêt brusque du tambour met en service un dispositif compZémentaire de n'importe quel type (non précisé) qui produit la coupure de l'alimentation électrique du moteur entratnant le tambour 2.  The position shown in Figure 2 corresponds to the mechanical locking of the drum 2 Zors the latter turns to the left with the door open. It can be observed that in this case, the hooks 7 of the lower flap 3 of the door come to grip on the projecting rim 10a. It is obvious that the sudden stop of the drum puts into service an additional device of any type (not specified) which produces the cut in the electrical supply of the motor driving the drum 2.
