Abstract

1. An apparatus comprising receptacles for products which during operation of the apparatus and in a stationary state of the receptacles are discharged by means of a circular liquid vortex produced in said receptacles, characterised in that each of said receptacles (9, 10) in the operative position includes a sidewall which is formed by a so-called circular wall having a deep portion with a barrier (22, 23) for retaining a product to be discharged and selected from among powdery, paste-like or liquid products, and by an upper portion which has an outwardly opening region (18, 19) starting at least at the barrier (22, 23), said region being used both as charging opening for the product and inlet for a tangential injection of the liquid discharging the product toward the circular wall and as overflow-discharge opening for the "product and liquid" mixture which overflows said barrier (22, 23) under the action of the circular vortex of said liquid.

Description

La présente invention concerne un appareil tel qu'une machine à laver le linge ou la vaisselle, un appareil à distribution de produit en solution, etc.., muni de boîtes à produits.The present invention relates to an apparatus such as a washing machine for washing clothes or dishes, an apparatus for dispensing product in solution, etc., provided with boxes for products.

Dans une machine à laver, par exemple, des produits lessiviels en poudre ou en liquide sont habituellement utilisés et les boîtes ou bacs connus qui les contiennent, sont conçus de manières différentes. Quand il s'agit d'un produit en poudre, la boîte ou le bac d'entreposage connu comprend fréquemment soit une paroi latérale ouverte de haut en bas soit un ou plusieurs trous formés au niveau de son fond, destinés à l'évacuation du produit. Dans une telle boîte ou bac, le produit en poudre déposé dans un endroit éloigné de cette paroi ouverte ou ces trous, en absence de l'eau, reste en tas et ne s'en va pas ou ne se déverse pas dans la cuve de la machine. Lors d'une introduction de l'eau dans cette boîte ou bac, le produit pulvérulent est entraîné par l'eau à travers cette paroi ouverte ou ces trous, dans la cuve de la machine.In a washing machine, for example, detergents in powder or liquid form are usually used and the known boxes or tubs which contain them are designed in different ways. In the case of a powdered product, the known storage container or box frequently comprises either a side wall open from top to bottom or one or more holes formed at its bottom, intended for the evacuation of the product. In such a box or tray, the powdered product deposited in a place remote from this open wall or these holes, in the absence of water, remains in a heap and does not go away or spill into the tank. the machine. When water is introduced into this box or tank, the pulverulent product is entrained by the water through this open wall or these holes, in the tank of the machine.

Par contre pour un produit liquide, la boîte ou le bac d'entreposage comprend des parois fermées, et l'évacuation du produit se fait habituellement par un siphon qui s'amorce après une adjonction d'eau dans cette boîte ou bac.On the other hand, for a liquid product, the storage box or tank has closed walls, and the product is usually discharged by a siphon which starts after adding water to this box or tank.

Dans les appareils connus, la plupart de ces boîtes ou bacs d'entreposage conçus pour un produit pulvérulent ne sont pas aptes à recevoir un produit liquide ou inversement quand ces boîtes sont prévues pour un produit liquide, elles ne fonctionnent pas correctement pour un produit pulvérulent. Un changement d'état physique des produits lessiviels utilisés exige un changement de type de boîte ou l'utilisation d'un dispositif d'adaptation.In known devices, most of these boxes or storage tanks designed for a pulverulent product are not capable of receiving a liquid product or conversely when these boxes are intended for a liquid product, they do not function properly for a pulverulent product . A change in the physical state of the detergents used requires a change in the type of box or the use of an adaptation device.

Ces solutions onéreuses grèvent le prix de revient de l'appareil fabriqué.These expensive solutions add to the cost price of the device manufactured.

Certains appareils connus comprennent des boîtes à produits pouvant recevoir soit un produit liquide soit un produit pulvérulent. Cependant leur structure ou forme ne permet pas habituellement soit une évacuation rapide ou totale du produit ou du liquide véhiculant qui chasse le produit et/ou une fabrication économique soit un fonctionnement avec une absence de pièces mécaniques en mouvement.Certain known devices include boxes for products which can receive either a liquid product or a pulverulent product. However, their structure or shape does not usually allow either rapid or total evacuation of the product or of the conveying liquid which drives out the product and / or economical manufacture, or operation with an absence of moving mechanical parts.

Dans une boîte à produits travaillant avec ses pièces mécaniques en mouvement, il y a un risque de blocage ou de mauvais fonctionnement de celles-ci, qui entraîne par conséquent un mauvais résultat de fonctionnement de cette boîte.In a product box working with its moving mechanical parts, there is a risk of blocking or improper functioning thereof, which consequently results in a poor operating result of this box.

La présente invention ayant pour but d'éviter ces inconvénients, permet de réaliser un appareil économique dans lequel une boîte universelle à produits peut fonctionner indifféremment avec un produit pulvérulent liquide ou pâteux.The aim of the present invention is to avoid these drawbacks, which makes it possible to produce an economical device in which a universal product container can function equally well with a liquid or pasty pulverulent product.

Selon l'invention, un appareil muni de boîtes à produits dont la distribution au cours du fonctionnement de cet appareil, se fait par évacuation par trop plein d'un mélange formé de ces produits et d'un liquide tel que de l'eau injecté dans ces boîtes, comprend comme boîtes à produits, au moins une boîte universelle statique fonctionnant à tourbillon circulaire d'eau d'entraînement et à déversement par trop plein.According to the invention, an apparatus provided with boxes of products, the distribution of which during the operation of this apparatus, is done by evacuation by overflow of a mixture formed of these products and of a liquid such as injected water. in these boxes, includes as product boxes, at least one universal static box operating with a circular vortex of drive water and with overflow.

Pour mieux faire comprendre l'invention on décrit ci-après un exemple de réalisation illustré par des dessins ci-annexés dont

  • - la figure 1 représente une vue partielle et schématique d'une machine à laver le linge à chargement par le dessus, réalisée selon l'invention, montrant la porte de la machine, dans une position de fermeture, et
  • - la figure 2 représente une vue partielle et schématique de la machine de la figure 1, en coupe suivant un plan II-II.
In order to better understand the invention, an exemplary embodiment is illustrated below, illustrated by the attached drawings,
  • FIG. 1 represents a partial and schematic view of a top-loading washing machine, produced according to the invention, showing the door of the machine, in a closed position, and
  • - Figure 2 shows a partial and schematic view of the machine of Figure 1, in section along a plane II-II.

Une machine à laver le linge 1, selon un exemple de réalisation de l'invention illustré dans les figures 1 et 2, comprend une carrosserie 2, une cuve 3 et un tambour à linge 4. La machine 1 à chargement par le dessus, est formée par une porte 5 pivotant autour d'un axe horizontal 6.A washing machine 1, according to an exemplary embodiment of the invention illustrated in Figures 1 and 2, comprises a bodywork 2, a tank 3 and a laundry drum 4. The top-loading machine 1 is formed by a door 5 pivoting about a horizontal axis 6.

Selon une caractéristique importante de l'invention la porte 5 est munie dans sa surface intérieure 7 au moins d'une boîte universelle statique à produits 9 fonctionnant à tourbillon circulaire d'eau d'entraînement et à déversement par trop plein. Dans l'exemple illustré, la porte 5 comprend un ensemble amovible 8 de deux boîtes universelles jumelées statiques 9 et 10, pour produits lessiviels pulvérulents, liquides ou pâteux en saillie dans l'ouverture 11 de la cuve 3 lors d'une mise de cet ensemble 8 dans sa position de fonctionnement, par une fermeture de la porte 5. Ces boîtes 9 et 10 complètement séparées par leur paroi ne sont pas communicantes. Suivant cette position de fonctionnement de l'ensemble 8, les boîtes universelles 9 et 10 comprennent respectivement des parois latérales circulaires ou cylindriques 12, 13, des parois d'extrémité 14, 15, 16, 17 et des entrées 18, 19 prolongées latéralement par des becs en forme d'entonnoirs 20, 21. Les entrées 18, 19 sont formées dans les parois latérales circulaires ou cylindriques 12, 13 sur une partie seulement de leur largeur ou hauteur, et plus près des parois d'extrémité 14, 16 qui représentent les parois supérieures des boîtes 9 et 10 quand l'ensemble 8 se trouve dans sa position de fonctionnement. Il en résulte que dans cette position de fonctionnement des boîtes 9 et 10 (figure 1), les parois d'extrémités 15, 17 qui représentent les parois inférieures, se trouvent à un niveau inférieur à celui des seuils 22, 23 des entrées 18, 19. Cette dénivélation ou la hauteur des seuils 22, 23 définit la dose maximale de produit notamment liquide pouvant être retenue par les boîtes 9 et 10. Si sa quantité est trop importante, le produit liquide s'évacue par débordement de ces seuils 22, 23 selon un déversement par trop plein.According to an important characteristic of the invention, the door 5 is provided in its inner surface 7 with at least one universal static product container 9 operating with a circular vortex of drive water and with overflow. In the example illustrated, the door 5 comprises a removable assembly 8 of two static twin universal boxes 9 and 10, for powdery, liquid or pasty detergents projecting into the opening 11 of the tank 3 during placing of this together 8 in its operating position, by closing the door 5. These boxes 9 and 10 completely separated by their wall are not communicating. According to this operating position of the assembly 8, the universal boxes 9 and 10 respectively comprise circular or cylindrical side walls 12, 13, end walls 14, 15, 16, 17 and inlets 18, 19 extended laterally by funnel-shaped spouts 20, 21. The inlets 18, 19 are formed in the circular or cylindrical side walls 12, 13 over only part of their width or height, and closer to the end walls 14, 16 which represent the upper walls of the boxes 9 and 10 when the assembly 8 is in its operating position. As a result, in this operating position of the boxes 9 and 10 (FIG. 1), the end walls 15, 17 which represent the lower walls, are at a level lower than that of the thresholds 22, 23 of the inputs 18, 19. This difference in level or the height of the thresholds 22, 23 defines the maximum dose of product, in particular liquid, which can be retained by the boxes 9 and 10. If its quantity is too large, the liquid product is evacuated by overflowing of these thresholds 22, 23 in an overflow spill.

Quand l'ensemble 8 est mis dans sa position de recharge par soulèvement de porte 5 dans sa position verticale non représentée, les entrées 18 et 19 des boîtes 9 et 10 sont orientées vers le haut, et les becs en forme d'entonnoirs 20, 21 facilitent le remplissage de ces boîtes en produits lessiviels pulvérulents, liquides ou pâteux. Lors d'une remise de cet ensemble 8 dans sa position de fonctionnement (figure 1) les doses de produits lessiviels se trouvant dans les boîtes 9 et 10 sont retenues par les seuils 22, 23 des entrées 18, 19.When the assembly 8 is put in its recharging position by lifting the door 5 in its vertical position not shown, the inlets 18 and 19 of the boxes 9 and 10 are oriented upwards, and the spouts in the form of funnels 20, 21 facilitate the filling of these boxes in powdered, liquid or pasty detergents. When this assembly 8 is returned to its operating position (FIG. 1), the doses of detergents found in the boxes 9 and 10 are retained by the thresholds 22, 23 of the inputs 18, 19.

Les boîtes universelles 9 et 10 comprennent respectivement dans leurs parois d'extrémité 15, 17 qui représentent leurs parois inférieures dans leur position de fonctionnement (figure 1), des trous 30 et 31 d'évacuation d'eau. Etant donné que les produits liquides utilisés ont un degré de viscosité supérieur à celui de l'eau utilisée dans les machines à laver, les diamètres des trous 30 et 31 sont déterminés de manière que ces trous laissent passer de l'eau mais empêchent le passage des produits liquides. La dimension de ces trous 30, 31 est également déterminée de manière qu'un produit pulvérulent déposé dans ces boîtes ne puisse s'échapper par ces trous.The universal boxes 9 and 10 respectively comprise in their end walls 15, 17 which represent their lower walls in their operating position (FIG. 1), holes 30 and 31 for discharging water. Since the liquid products used have a higher degree of viscosity than that of the water used in washing machines, the diameters of the holes 30 and 31 are determined so that these holes allow water to pass but prevent passage liquid products. The dimension of these holes 30, 31 is also determined so that a pulverulent product deposited in these boxes cannot escape through these holes.

La machine à laver 1 comprend en outre d'une part un système d'injection d'eau 24 du type connu dont les buses 25, 26, 27 sont schématiquement représentées dans la figure 2, et d'autre part certains bacs de type connu 28, 29 pour des produits tels que assouplissant, eau de javel etc...The washing machine 1 further comprises on the one hand a water injection system 24 of the known type, the nozzles 25, 26, 27 of which are schematically represented in FIG. 2, and on the other hand certain tanks of known type 28, 29 for products such as fabric softener, bleach etc ...

Le système d'injection d'eau 24 commandé par un programmateur de type connu non représenté, est monté dans la machine à laver 1, en vis à vis des boîtes universelles 9 et 10 et des bacs 28, 29 à produits (figures 1 et 2). Ce système 24 permet d'envoyer par la buse 25 un jet d'eau 32 à travers l'entrée 19 dans la boîte universelle 10, presque tangentiellement à la paroi circulaire ou cylindrique 13 de celle-ci, par la buse 26, un jet d'eau 33 à travers l'entrée 18 dans la boîte universelle 9, presque tangentiellement à la paroi circulaire ou cylindrique 12 de celle-ci, par les deux buses 25, 26 de l'eau, résultant de la collision des jets d'eau 32 et 33, et recueillie par une gouttière 34, dans le bac 29, et par la buse 27, un jet d'eau 35, à travers un trou 36 de la paroi 37, dans le bac 28.The water injection system 24 controlled by a known type of programmer not shown, is mounted in the washing machine 1, opposite the universal boxes 9 and 10 and product bins 28, 29 (Figures 1 and 2). This system 24 makes it possible to send a jet of water 32 through the nozzle 25 through the inlet 19 into the universal box 10, almost tangentially to the circular or cylindrical wall 13 thereof, via the nozzle 26, a jet of water 33 through the inlet 18 in the universal box 9, almost tangentially to the circular or cylindrical wall 12 thereof, by the two nozzles 25, 26 of water, resulting from the collision of the jets of water 32 and 33, and collected by a gutter 34, in the tank 29, and by the nozzle 27, a jet of water 35, through a hole 36 in the wall 37, in the tank 28.

Les boîtes universelles 9 et 10 et les bacs 28, 29 étant remplis de leurs doses respectives de produits et mis en position de fonctionnement par la fermeture de la porte 5, à un moment déterminé du cycle de lavage où le produit dans la boîte universelle 9 par exemple doit être distribué dans la cuve 3 de la machine 1, la buse 26 envoie un jet d'eau 33 dans la boîte 9. Ce jet d'eau, qui est presque tangentiel à la paroi latérale circulaire ou cylindrique 12, engendre un mouvement circulaire d'eau et crée en conséquence un tourbillon circulaire qui soulève et entraîne au passage le produit pulvérulent, liquide ou pâteux se trouvant dans la boîte 9. Le mélange d'eau et de produits, guidé par le bec 20, se déverse dans la cuve 3 dès que son niveau dépasse le seuil 22 de l'entrée 18. Dans la boîte universelle 9, ce mélange étant fortement concentré en produits au début de l'injection d'eau, se dilue progressivement par l'arrivée de l'eau et par l'évacuation du mélange par trop plein, et devient, à la fin de l'opération, uniquement de l'eau. Le programmateur arrête le jet d'eau 33, et l'eau résiduelle restant dans la boîte universelle 9 s'évacue par le trou 30 et tombe dans la cuve 3.The universal boxes 9 and 10 and the tanks 28, 29 being filled with their respective doses of products and placed in the position of operation by closing the door 5, at a determined point in the washing cycle where the product in the universal box 9 for example must be distributed in the tank 3 of the machine 1, the nozzle 26 sends a jet of water 33 into the box 9. This water jet, which is almost tangential to the circular or cylindrical side wall 12, generates a circular movement of water and consequently creates a circular vortex which lifts and entrains the pulverulent, liquid or pasty product in passing being in the box 9. The mixture of water and products, guided by the spout 20, pours into the tank 3 as soon as its level exceeds the threshold 22 of the inlet 18. In the universal box 9, this mixture being highly concentrated in products at the start of the water injection, gradually dilutes by the arrival of the water and by the evacuation of the mixture by overflow, and becomes, at the end of the operation, only of the water. The programmer stops the water jet 33, and the residual water remaining in the universal box 9 is evacuated through the hole 30 and falls into the tank 3.

Le fonctionnement de la boîte universelle 10 avec le jet d'eau 32 envoyé par la buse 25 est analogue à celui de la boîte universelle 9, décrit ci-dessus.The operation of the universal box 10 with the water jet 32 sent by the nozzle 25 is similar to that of the universal box 9, described above.

La puissance des jets d'eau quasi tangentiels 32, 33 et celle des tourbillons circulaire d'eau engendrés, permettent de créer facilement des mélanges aqueux avec un grand nombre de produits utilisés qui peuvent se présenter sous des états divers, pulvérulents liquides ou pâteux, et de les évacuer efficacement par déversement par trop plein dès que leurs niveaux dépassent les seuils 22, 23 des entrées 18, 19 de ces boîtes.The power of the almost tangential water jets 32, 33 and that of the circular vortices of water generated, make it possible to easily create aqueous mixtures with a large number of products used which can occur in various states, liquid or pasty powders, and to evacuate them effectively by overflow spillage as soon as their levels exceed the thresholds 22, 23 of the inlets 18, 19 of these boxes.

Les parois 12 et 13 sont des parois circulaires. Ce sont des parois dont leur section transversale forme un cercle ou un polygone régulier fermé. Autrement dit les parois non circulaires sont des parois formées par un assemblage d'éléments de formes et de longueurs hétérogènes. Ces parois comportent par exemple des zones courbes mélangées par des zones rectilignes ou planes ou des bossages ou des creux. Dans une boîte munie de parois non circulaires un jet d'eau admis tangentiellement à ces parois ne peut pas y créer un ou des tourbillons circulaires qui soulévent et évacuent par déversement par trop plein les produits mais des remous et des tourbillons incontrolés qui se dirigent parfois dans des sens opposés, se neutralisent et ne balayent pas certaines zones de la boîte à produits, de manière à laisser ces produits y séjourner sans les évacuer. L'efficacité de l'évacuation est par conséquent fortement diminuée.The walls 12 and 13 are circular walls. These are walls whose cross section forms a closed regular circle or polygon. In other words, the non-circular walls are walls formed by an assembly of elements of heterogeneous shapes and lengths. These walls comprise, for example, curved zones mixed by rectilinear or flat zones or bosses or hollows. In a box fitted with non-circular walls a jet of water admitted tangentially to these walls cannot create one or more circular vortices which lift and evacuate the products by overflow, but uncontrolled eddies and vortices which sometimes go in opposite directions, neutralize and do not sweep certain areas of the product box, so as to let these products stay there without evacuating them. The efficiency of the evacuation is therefore greatly reduced.

Selon l'invention, la machine à laver 1 peut comprendre un nombre de boîtes universelles à produits, inférieur ou supérieur à deux.According to the invention, the washing machine 1 can comprise a number of universal boxes for products, less than or more than two.

Grâce à leur structure simple, économique et leur fonctionnement efficace l'utilisation des boîtes universelles 9 ou 10 pour une distribution d'un produit pulvérulent, liquide ou pâteux dans un appareil, ne grève pas le prix de revient de ce dernier et ne compromet nullement son fonctionnement. Pour un appareil muni de ces boîtes universelles 9 ou 10, le choix des produits à y mettre, par l'utilisateur devient relativement plus libre car ce choix se fait indépendamment de l'état physique, pulvérulent, liquide ou pâteux de ces produits, ce qui constitue encore un autre grand avantage vis à vis d'un appareil équipé de boîtes ou de bacs d'entreposage distinctes de conception connue, pour produits pulvérulents et pour produits liquides.Thanks to their simple, economical structure and efficient operation, the use of universal boxes 9 or 10 for dispensing a pulverulent, liquid or pasty product into a device does not strike the cost price of the latter and does not in any way compromise its operation. For a device provided with these universal boxes 9 or 10, the choice of the products to be put therein, by the user becomes relatively freer because this choice is made independently of the physical, pulverulent, liquid or pasty state of these products, which constitutes yet another great advantage with respect to a device equipped with boxes or separate storage bins of known design, for powdered products and for liquid products.
