Description

La présente invention concerne un procédé de lavage et de nettoyage, du linge en machine à laver, dans lequel un agent de détergence liquide est introduit progressivement dans le milieu de lavage à partir d'un dispositif rechargeable placé dans le tambour de la machine avec le linge à laver : l'invention concerne aussi le dispositif pour la mise en oeuvre de ce procédé.The present invention relates to a method of washing and cleaning laundry in a washing machine, in which a liquid detergent is gradually introduced into the washing medium from a rechargeable device placed in the drum of the machine with the washing machine: the invention also relates to the device for implementing this process.

Des compositions détergentes liquides pour le lavage du linge se trouvent sur le marché. Elles ont diverses propriétés avantageuses par rapport aux nombreuses compositions détergentes granulaires, mais leur utilisation ne s'est pas répandue autant qu'on aurait pu le penser compte- tenu de leurs qualités, du fait d'une certaine inadaptation à l'emploi dans la plupart des machines à laver le linge actuellement sur le marché.Liquid detergent compositions for washing clothes are on the market. They have various advantageous properties compared to the numerous granular detergent compositions, but their use has not spread as far as one might have thought given their qualities, due to a certain unsuitability for use in the most of the washing machines currently on the market.

En effet, que ces machines soient à ouverture frontale et tambour rotatif horizontal, ou à chargement par le haut, les distributeurs pour la dose d'agent détergent utilisée à chaque cycle de lavage, sont, en général, mal adaptés au recueil d'agents liquides et à leur dispersion ultérieure dans le bain de lavage; la plupart des machines actuellement utilisées par les ménagères ont en effet été conçues alors qu'il n'y avait sur le marché que des lessives en poudre ou en granules.Indeed, whether these machines are front opening and horizontal rotary drum, or top loading, the dispensers for the dose of detergent agent used in each washing cycle are, in general, ill-suited to the collection of agents liquids and their subsequent dispersion in the washing bath; most of the machines currently used by housewives were in fact designed when there were only powder or granular detergents on the market.

La demanderesse a constaté que, fréquem- ment, une partie de la composition détergente liquide mise dans le distributeur de la machine, avant de la mettre en route, était inutilisable pour le lavage.The Applicant has found that, frequently, part of the liquid detergent composition put in the machine's dispenser, before starting it up, is unusable for washing.

En effet, le produit de lavage est totalement entraîné avec les premiers ml d'eau introduits dans la machine, et ceux-ci, dans la plupart des cas, vont aller directement remplir les circuits de vidange de la machine dans lesquels l'opération de lavage précédente n'avait laissé que très peu d'eau.Indeed, the detergent is completely entrained with the first ml of water introduced into the machine, and these, in most cases, will go directly to fill the drain circuits of the machine in which the operation of previous wash had left very little water.

Lorsque le produit de lavage a pénétré dans ce circuit, il ne migrera pratiquement plus vers le bain de lavage imprégnant le linge, que ce soit au cours du remplissage de la machine, ou au cours du lavage proprement dit, et il sera éliminé avec la première vidange. Les pertes, c'est-à-dire le produit de lavage inutilisé, peuvent être importantes particulièrement dans certains types de machines à laver où une proportion non négligeable de la composition liquide mise dans le distributeur prévu pour un produit de lavage solide, ne seront pas utilisés. Le niveau de perte dépend notamment du volume du circuit de vidange avant la pompe, de la vitesse d'arrivée de l'eau, de la position du point d'entrée de l'eau. On conçoit qu'une méthode de lavage en machine utilisant un détergent liquide soit, dans un certain nombre de cas, plus coûteuse qu'elle ne devrait, et il n'est pas surprenant que la ménagère, dans l'ignorance des pertes subies, préfère s'abstenir d'utiliser un détergent liquide, malgré ses propriétés avantageuses.When the detergent has entered this circuit, it will practically no longer migrate towards the washing bath impregnating the laundry, whether during the filling of the machine, or during the actual washing, and it will be eliminated with the first drain. The losses, that is to say the unused detergent, can be significant, particularly in certain types of washing machines where a significant proportion of the liquid composition put in the dispenser intended for a solid detergent, will not be not used. The level of loss depends in particular on the volume of the drainage circuit before the pump, the speed of arrival of the water, the position of the water entry point. It is understandable that a machine washing method using a liquid detergent is, in a certain number of cases, more expensive than it should, and it is not surprising that the housewife, in ignorance of the losses suffered, prefers to refrain from using a liquid detergent, despite its advantageous properties.

Ainsi, la présente invention, qui permet de supprimer ces pertes inévitables, est particulièrement utile.Thus, the present invention, which eliminates these unavoidable losses, is particularly useful.

Elle concerne un procédé perfectionné de lavage et nettoyage du linge dans une machine à laver d'un type courant dans lequel on utilise un agent de détergence à l'état liquide, dont la viscosité est telle qu'il peut s'écouler librement, même à température ambiante. Selon ce procédé perfectionné, ledit agent est libéré progressivement dans le bain de lavage à partir d'un dispositif placé dans le tambour de la machine avec le linge à laver, au lieu d'être introduit à partir du distributeur prévu par le constructeur de la machine à laver pour recevoir le produit de lavage.It relates to an improved process for washing and cleaning linen in a washing machine. washing of a common type in which a detergent is used in the liquid state, the viscosity of which is such that it can flow freely, even at room temperature. According to this improved process, said agent is gradually released into the washing bath from a device placed in the drum of the machine with the laundry to be washed, instead of being introduced from the distributor provided by the manufacturer of the washing machine to receive the washing product.

Le procédé consiste à verser dans un dispositif convenable une quantité prédéterminée - en fonction notamment de la quantité du linge à laver, du degré des salissures, de la capacité de la machine - d'un agent de détergence liquide, à placer ensuite le dispositif dans le tambour de la machine avec le linge à laver, puis à mettre en route et laisser se dérouler le cycle de lavage habituel de la machine, le dispositif contenant le produit de lavage étant placé de préférence vers le haut de la cuve, dans le tambour. Ainsi, comme dans la plupart des machines à laver actuelles le tambour n'entre en rotation que lorsque le remplissage de la cuve est terminé, le dispositif ne commencera à se vider qu'en présence d'une quantité suffisante d'eau pour éviter le contact prolongé du linge sec ou juste humide avec le détergent concentré. Mais, il est aussi possible de placer le dispositif au fond du tambour, notamment dans le cas où celui-ci entre en rotation dès le début de l'admission de l'eau, ou même au milieu du linge. La ménagère choisira sans difficulté la position la mieux adaptée aux circonstances particulières de son lavage.The method consists in pouring into a suitable device a predetermined quantity - depending in particular on the quantity of the laundry to be washed, the degree of soiling, the capacity of the machine - of a liquid detergent, then placing the device in the drum of the machine with the laundry to be washed, then to start and let run the usual washing cycle of the machine, the device containing the washing product being preferably placed at the top of the tank, in the drum . Thus, as in most current washing machines the drum does not rotate until the filling of the tub is completed, the device will not begin to empty until there is a sufficient amount of water to avoid the prolonged contact of dry or just damp laundry with concentrated detergent. However, it is also possible to place the device at the bottom of the drum, in particular in the case where the latter enters in rotation from the start of the admission of water, or even in the middle of the laundry. The housewife will easily choose the position best suited to the particular circumstances of her washing.

A la fin de l'essorage, le dispositif est sortie de la machine à laver avec le linge propre et mis de côté pour une utilisation ultérieure.At the end of the spin, the device came out of the washing machine with the clean cloth and set aside for later use.

Ce dispositif, qui est un autre objet de l'invention, comporte au moins un orifice de remplissage, de dimensions suffisantes pour que l'introduction de l'agent de lavage soit facile quelle qu'en soit la viscosité et la forme de l'embouchure du récipient qui contenait l'agent. Cet orifice est muni de moyens de fermeture adaptés qui peuvent être mobiles, solidaires ou non du corps du dispositif, tels les bouchons, capsules et autres, ou à demeure, telles les-cheminées fixées autour du col de l'orifice et rentrant dans le dispositif dont la longueur et le diamètre à l'extrémité interne sont tels qu'un liquide ayant pénétré dans le dispositif n'en ressort pratiquement pas. On conçoit que, dans ce dernier cas, l'orifice de remplissage puisse se confondre avec l'un des évents pour liquide, dont doit être muni le dispositif. Le nombre et la forme de ces évents pour liquide ne sont pas critiques; on peut avoir un seul évent, deux à dix ou une multitude de très petits évents, jusqu'à 100 environ; on préfère les dispositifs munis de deux à quatre évents par où le liquide sera libéré progressivement. Le diamètre des évents est généralement compris entre 2 mm et 10 mm pour les dispositifs en comportant de 2 à 8.This device, which is another object of the invention, comprises at least one filling orifice, of sufficient dimensions so that the introduction of the washing agent is easy whatever the viscosity and the shape of the mouth of the container which contained the agent. This orifice is provided with suitable closing means which may be movable, integral or not with the body of the device, such as plugs, capsules and the like, or permanently, such as chimneys fixed around the neck of the orifice and entering the device whose length and diameter at the internal end are such that a liquid having penetrated into the device practically does not come out of it. It is understood that, in the latter case, the filling orifice can be confused with one of the liquid vents, with which the device must be provided. The number and shape of these liquid vents is not critical; you can have a single vent, two to ten or a multitude of very small vents, up to about 100; devices with two to four vents are preferred, through which the liquid will be gradually released. The diameter of the vents is generally between 2 mm and 10 mm for devices comprising from 2 to 8.

Il est évident que tous les évents pour le liquide n'étant pas en général munis de systèmes de fermeture, doivent être situés au-dessus du niveau maximum de remplissage du dispositif; leurs positions respectives peuvent être quelconques, par contre. L'homme du métier sera à même de déterminer, par des essais de routine, le nombre de ces évents, en fonction de leur forme, de leur position et de la viscosité de l'agent de lavage liquide utilisé, de telle sorte que la toté- lité dudit agent soit déversée dans le bain de lavage en 1 à 10 minutes environ, de préférence en 3 minutes environ. Il faut évidemment tenir compte du fait que, pour un même dispositif rempli avec un agent de lavage donné, la durée de vidange sera fonction du diamètre du tambour de la machine dans lequel il sera utilisé, de sa cadence de rotation, et même du taux de remplissage en linge du tambour.It is obvious that all the vents for the liquid not being generally provided with closing systems, must be located above the maximum level of filling of the device; their respective positions can be any, however. The skilled person will be able to to determine, by routine tests, the number of these vents, according to their shape, their position and the viscosity of the liquid washing agent used, so that all of said agent is poured into the washing bath in approximately 1 to 10 minutes, preferably in approximately 3 minutes. It must obviously be taken into account that, for the same device filled with a given washing agent, the emptying time will depend on the diameter of the drum of the machine in which it will be used, its rate of rotation, and even the rate filling the drum with laundry.

Le dispositif peut être réalisé en matières diverses, qui doivent être incassables et résister jusqu'à une température de 100°C environ. De nombreux polymères synthétiques conviendront et par exemple le polyéthylène basse densité, le polypropylène ou d'autres élastomères.The device can be made of various materials, which must be unbreakable and resist up to a temperature of approximately 100 ° C. Many synthetic polymers will be suitable, for example low density polyethylene, polypropylene or other elastomers.

Selon une forme préférée de réalisation de l'invention, les parois du dispositif seront faites d'une matière transparente, ou comporteront une fenêtre transparente pour que la ménagère puisse voir le niveau atteint par le liquide dans le dispositif au cours de l'opération de remplissage, pour éviter tout débordement intempestif.According to a preferred embodiment of the invention, the walls of the device will be made of a transparent material, or will include a transparent window so that the housewife can see the level reached by the liquid in the device during the operation of filling, to avoid any untimely overflow.

Dans un mode de réalisation préféré, le dispositif porte des repères, indiquant le volume de liquide introduit lorsque le repère est atteint; un même dispositif sera alors utilisable pour des machines à laver de capacités différentes, ou permettra d'adapter la quantité d'agent de lavage à l'opération à effectuer.In a preferred embodiment, the device carries marks, indicating the volume of liquid introduced when the mark is reached; the same device can then be used for washing machines of different capacities, or will make it possible to adapt the quantity of washing agent to the operation to be carried out.

Le dispositif, par ailleurs, a une surface extérieure non rugueuse et ne présente pas d'angles vifs, pour éliminer tout risque d'usure prématurée du linge par frottements : ses parois sont relativement rigides, cependant, pour que la manipulation du dispositif rempli ne soit pas rendue difficile par leur déformation résultant de la .. pression exercée par les doigts qui le saisissent.The device, moreover, has a non-rough exterior surface and does not have sharp angles, to eliminate any risk of wear. premature washing by friction: its walls are relatively rigid, however, so that the handling of the filled device is not made difficult by their deformation resulting from the .. pressure exerted by the fingers which grip it.

Dans une forme de réalisation préférée, le dispositif comportera une base suffisamment large pour qu'il soit parfaitement stable et qu'un geste maladroit, notamment au cours de son remplissage avec l'agent de lavage, n'entraîne pas son renversement.In a preferred embodiment, the device will have a sufficiently wide base so that it is perfectly stable and that an awkward gesture, in particular during its filling with the washing agent, does not cause its overturning.

Des moyens de fixation du dispositif au tambour de la machine tels que ventouses ou crochets sont prévus dans une variante du dispositif de l'invention. Ils permettent de limiter le bruit dû au roulement du dispositif dans le tambour pendant le cycle de lavage et son frottement sur le linge pendant l'essorage, le dispositif est, de toutes façons, plaqué contre les parois du tambour avec le linge.Means for fixing the device to the machine drum such as suction cups or hooks are provided in a variant of the device of the invention. They limit the noise due to the rolling of the device in the drum during the washing cycle and its friction on the laundry during spinning, the device is, in any case, pressed against the walls of the drum with the laundry.

Dans le procédé de lavage et de nettoyage du linge selon l'invention, on remplit le dispositif décrit plus haut avec un agent de détergence liquide de viscosité généralement comprise entre O,1 et 0,4 Pas. Celui-ci comprend les composants habituels, c'est-à-dire au moins un tensio-actif avec un véhicule liquide, ainsi qu'éventuellement des adjuvants de détergence ("builders"), des régulateurs de mousse, des enzymes et leurs stabilisants, des agents de blanchiment, des agents de mise en suspension de salissures et des agents de conditionnement des textiles.In the method of washing and cleaning the linen according to the invention, the device described above is filled with a liquid detergent of viscosity generally between 0.1 and 0.4 Pas. This includes the usual components, that is to say at least one surfactant with a liquid vehicle, as well as optionally detergency builders, foam regulators, enzymes and their stabilizers. , bleaching agents, soil suspending agents and textile conditioning agents.

Les compositions de détergence liquides, utilisées dans le procédé de lavage de l'invention peuvent, en outre, contenir des aviveurs optiques, des parfums, des colorants, des opacifiants, des antioxydants, des agents bactéricides des charges et autres.Liquid detergent compositions, used in the washing process of the invention may, in addition, contain optical brighteners, perfumes, dyes, opacifiers, antioxidants, bactericidal fillers and the like.

Les tensio-actifs présents dans les compositions utilisées dans le procédé de l'invention peuvent être anioniques, non ioniques, ampholytes ou zwitterioniques; on peut aussi utiliser leurs mélanges. Des exemples de ces tensio-actifs sont cités'dans la demande de brevet EP-A-0028865; on peut y ajouter, en outre, un agent tensio-actif cationique comme dans cette demande de brevet, page 5, ligne 32 à page 7, ligne 21. La quantité de tensio-actif présente dans les compositions liquides est généralement comprise entre 5% et 70% en poids de l'ensemble, et elle est en général fonction de la présence ou non d'adjuvants de détergence; elle est inférieure en présence de ceux-ci. Parmi les adjuvants bien connus, on citera les sels alcalins des phosphates et polyphos- phates de l'acide nitrilotriacétique, de l'acide citrique ou encore les zéolites synthétiques.The surfactants present in the compositions used in the process of the invention can be anionic, nonionic, ampholyte or zwitterionic; one can also use their mixtures. Examples of these surfactants are cited in patent application EP-A-0028865; a cationic surfactant can also be added to it, as in this patent application, page 5, line 32 to page 7, line 21. The amount of surfactant present in the liquid compositions is generally between 5% and 70% by weight of the whole, and it is generally a function of the presence or absence of detergency builders; it is lower in the presence of these. Among the well-known adjuvants, mention will be made of the alkaline salts of phosphates and polyphosphates of nitrilotriacetic acid, of citric acid or also of synthetic zeolites.

Le véhicule liquide de la composition peut être de l'eau, un solvant organique tel que les mono et polyalcools aliphatiques ayant jusqu'à 6 atomes de carbone et leurs éthers ou leurs mélanges.The liquid vehicle of the composition can be water, an organic solvent such as aliphatic mono and polyalcohols having up to 6 carbon atoms and their ethers or their mixtures.

Parmi les composés facultatifs de la composition de lavage liquide, on peut citer les agents séquestrants, bien connus, tels que des po- lyacrylates, polymaléates et des copolymères d'acides insaturés et de méthyl vinyl éther, mais aussi les agents de suspension des salissures, tels que la polyvinyl pyrrolidone et la carboxy- méthylcellulose sodique, les hydrotropes tels que les sels d'acides alkyl aryl sulfonique et les régulateurs de mousse tels que les acides gras en C16 à C221 et les polysiloxanes. Tous ces composés peuvent être introduits dans des compositions de lavage liquides, utilisables dans le procédé selon l'invention, en quantités variables, bien connues du spécialiste.Among the optional compounds of the liquid washing composition, mention may be made of the sequestering agents, well known, such as polyacrylates, polymaleates and copolymers of unsaturated acids and of methyl vinyl ether, but also the agents for suspending soil , such as polyvinyl pyrrolidone and carboxy- sodium methylcellulose, hydrotropes such as salts of alkyl aryl sulfonic acids and foam regulators such as C 16 -C 221 fatty acids and polysiloxanes. All these compounds can be introduced into liquid washing compositions, which can be used in the process according to the invention, in variable amounts, well known to the specialist.

Des polydialkylsiloxanes peuvent également être introduits dans les compositions liquides de lavage pour leurs propriétés adoucissantes.Polydialkylsiloxanes can also be introduced into the liquid washing compositions for their softening properties.

La quantité d'agent de lavage liquide utilisée dans le procédé selon l'invention dépend évidemment de la composition de l'agent, de la nature et de l'état du linge à laver et de la capacité de la machine à laver. Les dispositifs selon l'invention pourront contenir de 100 à 400 ml environ de liquide et leur volume intérieur total sera d'environ 150 ml à environ 500 ml, mais on peut parfaitement concevoir des dispositifs plus petits pour des agents de lavage très efficaces, ou des dispositifs plus grands pour les machines à laver en usage dans les collectivités.The amount of liquid washing agent used in the process according to the invention obviously depends on the composition of the agent, on the nature and condition of the laundry to be washed and on the capacity of the washing machine. The devices according to the invention may contain from 100 to 400 ml of liquid approximately and their total internal volume will be from approximately 150 ml to approximately 500 ml, but it is perfectly possible to design smaller devices for very effective washing agents, or larger devices for washing machines in use in communities.
