Description

L'invention concerne une machine à laver le linge comportant un pot à produits de lavage en poudre ou liquide, aménagé au-dessus d'une cuve et comprenant une arrivée d'eau latérale horizontale pour l'alimentation en eau du pot à produit, un conduit permettant, par débordement le passage des produits dilués du pot dans l'espace interne de la cuve et enfin un siphon assurant une vidange totale de l'eau résiduelle contenue dans le pot après une opération de lavage. Une telle machine est connue de la demande de brevet européen n° 0 099 798.The invention relates to a washing machine comprising a jar of powder or liquid washing products, arranged above a tank and comprising a horizontal lateral water inlet for the supply of water to the product jar, a conduit allowing, by overflow the passage of the diluted products from the pot into the internal space of the tank and finally a siphon ensuring a total emptying of the residual water contained in the pot after a washing operation. Such a machine is known from European patent application No. 0 099 798.

La demande de brevet européen n° 0 099 798 a pour objet une machine à laver qui possède un pot à produit en poudre ou liquide. Dans l'utilisation des pots à produits de lessive en poudre ou liquide se pose, le problème de l'encrassement des pots par les lessives liquides visqueuses, lessives qui s'agglomérent avec le produit en poudre, lors d'une double utilisation. Se pose aussi, pour les mêmes raisons, le problème de l'obturation par encrassement des conduits de vidange desdits pots.The subject of European patent application No. 0999798 is a washing machine which has a jar of powder or liquid product. In the use of jars for powdered or liquid detergents arises, the problem of fouling the jars with viscous liquid detergents, detergents which agglomerate with the powdered product, during a double use. There is also, for the same reasons, the problem of plugging by fouling the emptying conduits of said pots.

Le pot à produit décrit dans la demande de brevet citée est muni d'une extrémité d'injection d'eau, montée à proximité du fond et associé à un conduit tubulaire d'alimentation en eau. Le conduit tubulaire coopère avec un siphon d'une part, par une dérivation qui alimente en eau le siphon et d'autre part par l'extrémité d'injection qui provoque une dépression à l'entrée dudit siphon pour en éviter l'obturation.The product container described in the cited patent application is provided with a water injection end, mounted near the bottom and associated with a tubular water supply duct. The tubular conduit cooperates with a siphon on the one hand, by a bypass which supplies water to the siphon and on the other hand by the injection end which causes a depression at the inlet of said siphon to avoid plugging.

Le dispositif décrit présente l'inconvénient d'être complexe, de posséder un réseau de tubes pouvant entrainer une obturation accidentelle, par exemple par effet de dépression que peut engendrer le siphon lors de la vidange de l'eau résiduelle contenue dans le pot en fin d'une opération de lavage.The device described has the drawback of being complex, of having a network of tubes which can cause an accidental closure, for example by the effect of depres that can generate the siphon when emptying the residual water contained in the pot at the end of a washing operation.

L'invention a pour objet une machine à laver le linge possédant un pot à produit de lavage en poudre ou liquide conçu pour éviter l'encrassement et l'engorgement de ses moyens de vidange par les différentes lessives. Elle est caractérisée en ce que le pot comporte une double paroi l'une intérieure l'autre extérieure, l'espace compris entre la double paroi étant en communication d'une part, avec l'arrivée d'eau par l'intermédiaire d'une bouche d'arrivée d'eau aménagée sur la paroi extérieure et d'autre part, avec le volume contenant du pot par l'intermédiaire d'au moins un trou aménagé sur la paroi intérieure, l'eau provenant de l'arrivée d'eau et alimentant le bac n'est plus conduite par un réseau de tubes susceptibles de se boucher; l'eau est canalisée par la double paroi. L'obturation des trous n'est plus possible car le peu de produit qui passe dans les trous se dilue dans l'eau contenue dans la double paroi.The subject of the invention is a washing machine with a jar of powder or liquid washing product designed to avoid clogging and clogging of its means of emptying by the various detergents. It is characterized in that the pot has a double wall, one inside the other and the outside, the space between the double wall being in communication on the one hand, with the arrival of water by means of a water inlet mouth fitted on the outer wall and on the other hand, with the volume containing the pot via at least one hole fitted on the inner wall, the water coming from the inlet water supplying the tank is no longer conducted by a network of tubes liable to clog; the water is channeled through the double wall. Sealing the holes is no longer possible because the little product that passes through the holes dilutes in the water contained in the double wall.

Dans une forme préférentielle de l'invention, le pot peut être composé d'au moins deux récipients démontables, l'un supérieur formant la paroi intérieure, l'autre inférieur formant la paroi extérieure, tous deux sensiblement parallélépipédiques et s'emboîtant l'un dans l'autre verticalement, pour former d'une part, une double cloison verticale et un double fond et d'autre part, un siphon pour la vidange du récipient inférieur. L'emboitement des récipients supérieur et inférieur permet un nettoyage facile du siphon, nettoyage relativement rare car l'eau résiduelle circulant dans l'espace compris dans la double paroi ne contient en concentration que très peu de lessive.In a preferred form of the invention, the pot can be composed of at least two removable containers, one upper forming the inner wall, the other lower forming the outer wall, both substantially parallelepipedal and interlocking the one in the other vertically, to form on the one hand, a double vertical partition and a double bottom and on the other hand, a siphon for emptying the lower container. The nesting of the upper and lower receptacles allows easy cleaning of the siphon, a relatively rare cleaning because the residual water circulating in the space included in the double wall contains in concentration very little detergent.

Avantageusement, le siphon peut être formé d'une part,d'un tube vertical solidaire du fond du récipient inférieur, moulé avec lui et le traversant pour communiquer avec l'espace interne de la cuve et d'autre part, d'un manchon sensiblement cylindrique vertical, fermé en sa partie supérieure, moulé dans le fond du récipient supérieur et chapeautant concentriquement ledit tube. Ainsi lors du démontage du pot à produit de lessive le siphon se décompose en deux tubes très facilement accessibles pour leur nettoyage éventuel.Advantageously, the siphon can be formed on the one hand, of a vertical tube integral with the bottom of the lower container, molded with it and passing through it to communicate with the internal space of the tank and on the other hand, of a sleeve sen vertically cylindrical, closed in its upper part, molded in the bottom of the upper container and concentrically covering said tube. So when disassembling the detergent container the siphon breaks down into two very easily accessible tubes for possible cleaning.

Dans une forme particulière de l'invention, le(s) trou(s) en forme de crevé, aménagé(s) sur la paroi intérieure, est(sont) un(des) ajutage(s) donnant aux jets une orientation parallèle au plan de la paroi ou, lorsque la paroi est courbe, au plan tangent à la surface de la paroi. Les trous peuvent avoir une toute autre forme comme par exemple la forme d'une saillie à la périphérie de laquelle seraient aménagés des trous, en douche, envoyant l'eau parallélement à la surface sur laquelle la saillie a été aménagée.In a particular form of the invention, the hole (s) in the form of a puncture, arranged on the inner wall, is (are) a nozzle (s) giving the jets an orientation parallel to the plane of the wall or, when the wall is curved, in the plane tangent to the surface of the wall. The holes may have a completely different shape, for example the shape of a projection at the periphery of which holes are arranged, in the shower, sending water parallel to the surface on which the projection has been arranged.

Dans une autre forme préférentielle de l'invention, les trous formant ajutages peuvent être placés de façon à réaliser une série de jets orientés circulairement. Les jets d'eau issus des trous provoquent, dans le pot, un mouvement d'eau tournant pour le mélange de l'eau et du produit de lavage. D'une autre façon, les trous formant ajutages sont aménagés sur la paroi intérieure formant le fond du récipient supérieur, le mouvement de l'eau est alors appelé "mouvement en vélodrome". En plus d'un mouvement tournant les trous ainsi placés provoquent un mouvement ascensionnel de l'eau contenue dans le pot, mouvement qui soulève, lorsqu'ils existent, les agglomérats de lessive en poudre pour les porter vers le conduit de débordement.In another preferred form of the invention, the holes forming nozzles can be placed so as to produce a series of jets oriented circularly. The water jets from the holes cause a rotating movement of water in the pot to mix the water and the detergent. In another way, the holes forming nozzles are arranged on the inner wall forming the bottom of the upper container, the movement of the water is then called "velodrome movement". In addition to a rotating movement, the holes thus placed cause an upward movement of the water contained in the jar, a movement which raises, when they exist, the agglomerates of powdered detergent to carry them towards the overflow conduit.

Dans une autre forme préférentielle de réalisation les parois intérieures et extérieures du pot constitue un double fond. Les parois latérales des deux récipients qui s'emboîtent viennent alors en contact l'une de l'autre, laissant seulement un espace formant un double fond ainsi qu'un espace permettant latéralement une communication entre le double fond et la bouche d'entrée d'eau.In another preferred embodiment, the interior and exterior walls of the pot constitute a double bottom. The side walls of the two receptacles which fit together then come into contact with one another, leaving only a space forming a double bottom as well as a space allowing laterally a communication between the double bottom and the inlet mouth d 'water.

La figure 1 représente une machine 1 à laver le linge à chargement par le dessus, avec sa porte de carrosserie 2 ouverte. Au-dessous de la porte 2 est aménagée une porte 3 de cuve. Parallèlement au plan du cadre de la porte 3 est aménagé un bac 4 fixe à produits de lessive et en particulier un pot 5 de produit de lavage en poudre ou liquide.Figure 1 shows a top-loading washing machine 1, with its body door 2 open. Below door 2 is a door 3 of the tank. Parallel to the plane of the frame of the door 3 is arranged a fixed tub 4 for detergents and in particular a jar 5 of washing powder or liquid.

La figure 2 est une vue en perspective du pot 5. Dans cet exemple de réalisation conforme à l'invention le pot est composé de deux récipients sensiblement parallélépipédiques, un récipient supérieur 6 monté par emboîtement vertical dans un récipient inférieur 7. L'emboîtement des récipients 6 et 7 permet ; par le fait que le récipient supérieur 6 a un volume extérieur inférieur au volume intérieur du récipient 7, de réaliser une double paroi formant d'une part, une double cloison 8 verticale, totale ou partielle et d'autre part, un double fond 9 total ou partiel. Une arrivée 10 d'eau chargée d'injecter l'eau dans le pot 5 est placée devant une bouche 11 qui communique avec l'espace compris entre les deux parois, cet espace est lui-même en communication avec des trous 12 en forme d'ajutage. Une partie du pot enlevée permet de montrer outre le double fond 9, un siphon 13 dont la fonction est de vidanger le récipient inférieur 7 et de ce fait le pot 5, en siphonant l'eau contenue dans le fond du récipient 7 entre les deux parois. Le siphon est réalisé d'une part, par un moulage lors du moulage du récipient inférieur 7 d'un tube 14 vertical qui traverse le fond du récipient pour communiquer avec l'espace interne de la cuve et d'autre part, par moulage avec le récipient supérieur 6 d'un manchon 15 vertical sensiblement cylindrique et fermé en bout, dans sa partie haute 16. Le manchon 15 s'emboîte concentriquement lors du montage du récipient supérieur 6 dans le récipient inférieur 7, en laissant un intervalle entre la partie haute 16 fermée et l'extrémité haute du tube 14.Figure 2 is a perspective view of the pot 5. In this embodiment according to the invention the pot is composed of two substantially parallelepiped containers, an upper container 6 mounted by vertical fitting in a lower container 7. The fitting of containers 6 and 7 allows; by the fact that the upper container 6 has an external volume less than the internal volume of the container 7, to produce a double wall forming on the one hand, a double vertical partition 8, total or partial and on the other hand, a double bottom 9 total or partial. A water inlet 10 responsible for injecting water into the pot 5 is placed in front of a mouth 11 which communicates with the space between the two walls, this space is itself in communication with holes 12 in the form of a 'nozzle. A part of the pot removed makes it possible to show, in addition to the double bottom 9, a siphon 13 whose function is to empty the lower container 7 and therefore the pot 5, by siphoning the water contained in the bottom of the container 7 between the two walls. The siphon is produced on the one hand, by a molding during the molding of the lower container 7 of a vertical tube 14 which crosses the bottom of the container to communicate with the internal space of the tank and on the other hand, by molding with the upper container 6 of a substantially cylindrical vertical sleeve 15 closed at the end, in its upper part 16. The sleeve 15 fits concentrically during assembly of the upper container 6 in the lower container 7, leaving a gap between the part high 16 closed and the high end of the tube 14.

Le contenu du pot formé d'un produit de lessive dilué est déversé dans l'espace interne de la cuve par débordement lorsque le mélange arrive au niveau d'une canalisation 17 de vidange.The content of the pot formed by a diluted detergent is poured into the internal space of the tank by overflowing when the mixture arrives at a drain line 17.

La figure 3 représente un pot à produit de lessive en coupe longitudinale et possédant une double cloison 8 verticale et un double fond 9. Dans cette forme de réalisation conforme à l'invention, l'arrivée d'eau 10 injecte l'eau dans la bouche 11 pour envahir l'espace compris entre la double paroi. L'eau contenue dans cet espace jaillit dans le récipient supérieur 6 par les trous 12. Les trous 12 peuvent être, de manière à simplifier la fabrication, réalisés par moulage soit sur le fond du récipient 6 soit sur la cloison verticale dudit récipient, soit simultanément sur le fond et la cloison verticale pour former une série d'ajutages. Chacun des ajutages a la forme d'un crevé réalisé par moulage ou encore si le récipient est métallique, par coupure de la tôle et emboutissage afin de former une saillie et créer un trou dont la section rectangulaire ou en forme d'arc est une surface sensiblement perpendiculaire à la surface dans laquelle il a été réalisé. Ainsi les jets d'eau sortant de ces ajutages paralèllement à la surface de paroi permettent d'obtenir lors du mélange des produits avec l'eau, soit un régime turbulent lorsque les jets sont orientés en opposition, soit un régime tournant lorsque les jets sont orientés circulairement. Les flèches sur les différentes figures donnent l'orientation des jets d'eau entrant dans le volume contenant du pot. Sur la figure 3 est représenté en coupe, le siphon 13 composé du tube 14 solidaire du récipient inférieur 7 ainsi que le manchon 15 lui-même solidaire du récipient supérieur 6.3 shows a jar of detergent in longitudinal section and having a double vertical partition 8 and a double bottom 9. In this embodiment according to the invention, the water inlet 10 injects the water into the mouth 11 to invade the space between the double wall. The water contained in this space gushes into the upper container 6 through the holes 12. The holes 12 can be, in order to simplify the manufacture, made by molding either on the bottom of the container 6 or on the vertical partition of said container, or simultaneously on the bottom and the vertical partition to form a series of nozzles. Each of the nozzles has the shape of a puncture produced by molding or even if the container is metallic, by cutting the sheet metal and stamping in order to form a projection and create a hole of which the rectangular or arc-shaped section is a surface. substantially perpendicular to the surface in which it was made. Thus the water jets leaving these nozzles parallel to the wall surface make it possible to obtain, during the mixing of the products with water, a turbulent regime when the jets are oriented in opposition, ie a revolving regime when the jets are oriented circularly. The arrows on the various figures give the orientation of the water jets entering the volume containing the pot. In FIG. 3 is shown in section, the siphon 13 composed of the tube 14 secured to the lower container 7 as well as the sleeve 15 itself secured to the upper container 6.

La figure 4 montre le sens du déplacement de l'eau dans le cas d'une orientation circulaire des jets lors d'un mélange eau-produit de lavage.Figure 4 shows the direction of water movement in the case of a circular orientation of the jets during a water-detergent mixture.

La figure 5 représente un pot à double fond 9 en coupe longitudinale. Dans cette forme de réalisation conforme à l'invention, l'espace entre la double paroi est réduit principalement à un espace entre les deux fonds des deux récipients espace occupant dans le plan horizontal le tout ou une partie des deux parois horizontales. Les trous 12 sont alors placés seulement dans le fond du récipient supérieur. Dans une forme particulière représentée sur la figure 6, les trous sont placés et leur ajutages orientés de façon à provoquer dans le pot de section rectangulaire un mouvement dit "vélodrome" de l'eau injectée. Dans ce mode de réalisation, il se produit un mouvement tournant avec, en plus, une composante verticale dé- placant vers le haut le mélange eau-produit par nappes sensiblement planes et horizontales, de cette manière les agglomérats de produit de lessive en poudre sont soulevés par le mouvement de l'eau pour être ensuite déversés dans l'espace interne de la cuve par le conduit de débordement.Figure 5 shows a double bottomed pot 9 in longitudinal section. In this embodiment according to the invention, the space between the double wall is reduced mainly to a space between the two bottoms of the two receptacles space occupying in the horizontal plane all or part of the two horizontal walls. The holes 12 are then placed only in the bottom of the upper container. In a particular form shown in Figure 6, the holes are placed and their nozzles oriented so as to cause in the pot of rectangular section a movement called "velodrome" of the injected water. In this embodiment, there is a rotating movement with, in addition, a vertical component moving the water-product mixture upwards in substantially flat and horizontal layers, in this way the agglomerates of powdered detergent are raised by the movement of the water and then poured into the internal space of the tank through the overflow pipe.
