Description

La prèsente invention concerne lave-linge pourvu d'une phase de trempage.The present invention relates to washing machines provided with a soaking phase.

Dans un lave-linge pour augmenter des performances de lavage, deux solutions connues ont été proposées, l'une consiste à augmenter dans une phase de lavage d'un cycle de fonctionnement, la température du liquide de lavage et l'autre à ajouter à une phase normale de lavage, une phase de prélavage à durée fixe où s'effectue un lavage court avec un brassage normal du linge dans un liquide muni de lessive et à une température de l'ordre de 30°C à 40°C, et une vidange du liquide en fin de cette phase de prélavage. On constate qu'une augmentation de la température du liquide de lavage favorise une action physico-chimique des produits lessiviels sur des salissures et rend plus efficace le lavage mais se révèle au delà d'un certain niveau, incompatible avec un certain nombre de textiles qui ne supportent pas une température trop forte.In a washing machine to increase washing performance, two known solutions have been proposed, one consisting in increasing the washing liquid temperature during an operating cycle, the temperature of the washing liquid and the other to be added to a normal washing phase, a pre-washing phase of fixed duration in which a short washing is carried out with normal stirring of the laundry in a liquid provided with detergent and at a temperature of the order of 30 ° C to 40 ° C, and draining the liquid at the end of this prewash phase. It is found that an increase in the temperature of the washing liquid promotes a physicochemical action of the detergents on dirt and makes washing more effective but is revealed beyond a certain level, incompatible with a certain number of textiles which do not tolerate too high a temperature.

Une adjonction d'une phase de prélavage à une phase normale de lavage dans un lave-linge donne un bon résultat de lavage. Cependant cette addition augmente fortement une consommation en eau, en énergie de chauffage et en lessive. La quantité de lessive utilisée pour les deux phases de prélavage et lavage peut alors dépasser 1,5 fois une dose habituelle de lessive pour une phase normale de lavage.Adding a prewash phase to a normal washing phase in a washing machine gives a good washing result. However, this addition greatly increases consumption of water, heating energy and detergent. The quantity of detergent used for the two prewash and washing phases can then exceed 1.5 times a usual dose of detergent for a normal washing phase.

La présente invention ayant pour but d'éviter ces inconvénients, permet de réaliser un lave-linge performant et économique en lavage, aussi bien pour un linge fragile sensible à la température, que pour un linge résistant à celle-ci.The aim of the present invention is to avoid these drawbacks and makes it possible to produce a high-performance washing machine which is economical in washing, both for fragile linen sensitive to temperature and for linen resistant to it.

Selon l'invention, un lave-linge pourvu dans ses cycles de fonctionnement, d'une phase de trempage, caractérisé en ce qu'il comprend dans son fonctionnement une phase de trempage du linge à durée réglable, suivie sans interruption dans le temps, par une phase de lavage du linge.According to the invention, a washing machine provided in its operating cycles with a soaking phase, characterized in that it includes in its operation a soaking phase of the laundry with adjustable duration, followed without interruption in time, through a washing phase.

Pour mieux faire comprendre l'invention on en décrit ci-après un certain nombre d'exemples de réalisation, illustrés dans un dessin ci-annexé qui représente des courbes de fonctionnement d'un lave-linge mettant en oeuvre l'invention.To better understand the invention, a number of embodiments are described below, illustrated in an appended drawing which represents operating curves of a washing machine implementing the invention.

Un lave-linge qui met en oeuvre l'invention comprend une cuve, un tambour à linge, un moteur d'entraînement, des éléments de chauffage du liquide de trempage de lavage ou de rinçage, des dispositifs d'alimentation en eau et en produits lessiviels et des systèmes de mesure de niveaux d'eau, et des organes de commande, qui sont ceux de types connus, et ne sont pas représentés et décrits en détail dans la suite.A washing machine which implements the invention comprises a tank, a washing drum, a drive motor, elements for heating the washing or rinsing soaking liquid, devices for supplying water and products. detergents and systems for measuring water levels, and control members, which are those of known types, and are not shown and described in detail below.

Selon l'invention, le lave-linge comprend dans ses cycles de fonctionnement, une phase de trempage à durée réglable, suivie sans interruption dans le temps par une phase de lavage, autrement dit, la phase de trempage n'étant pas séparée de la phase de lavage par un arrêt à durée indéterminée du lave-linge. Les organes de commande du lave-linge font passer automatiquement et directement la phase de trempage à la phase de lavage. Durant la phase de trempage et la phase de lavage, la température du liquide de trempage et du liquide de lavage est maintenue à une valeur relativement modique entre 30°C et 45°C.According to the invention, the washing machine comprises in its operating cycles, a soaking phase of adjustable duration, followed without interruption over time by a washing phase, in other words, the soaking phase is not separated from the washing phase by an indefinite stop of the washing machine. The washing machine controls automatically and directly switch from the soaking phase to the washing phase. During the soaking phase and the washing phase, the temperature of the soaking liquid and of the washing liquid is maintained at a relatively low value between 30 ° C. and 45 ° C.

Dans l'exemple illustré, cette température est de 40°C et représentée en trait plein par une courbe II, la température ambiante étant Ta.In the example illustrated, this temperature is 40 ° C. and represented in solid lines by a curve II, the ambient temperature being Ta.

Une dose d'un produit lessiviel prédéterminée pour un cycle de fonctionnement de ce lave-linge est introduite dans le liquide de trempage durant la phase de trempage. Aucune vidange de liquide n'est effectuée entre la phase de trempage et la phase de lavage, et durant ces deux phases. Le liquide introduit dans le lave-linge dans la phase de trempage constitue ainsi un liquide commun de trempage et de lavage du linge. La phase de trempage comprend un brassage court et suffisant du linge, effectué dans un début de cette phase, pour parfaire un mouillage total de ce linge avec le liquide de trempage pourvu de produit lessiviel, et un repos pour le restant de cette phase où le linge à l'état immobile est trempé dans ce liquide. Dans la phase de lavage qui suit la phase de trempage, le linge est soumis à un brassage continu à des cadences habituelles, du début à la fin de cette phase. Le brassage du linge est représenté par des ondulations, dans une courbe III du dessin ci-annexé. Ainsi dans la phase de trempage t₀ t₂, le brassage du linge occupe une partie du temps t₀-t₁ et un repos imposé à ce linge s'étend entre t₁ et t₂, et dans la phase de lavage t₂-t, le brassage du linge occupe tout le long de cette phase t₂-t.A dose of a predetermined detergent for an operating cycle of this washing machine is introduced into the soaking liquid during the soaking phase. No liquid is drained between the soaking phase and the washing phase, and during these two phases. The liquid introduced into the washing machine in the soaking phase thus constitutes a common liquid for soaking and washing the laundry. The soaking phase includes a short and sufficient stirring of the laundry, carried out at the beginning of this phase, to perfect a total wetting of this linen with the soaking liquid provided with detergent, and a rest for the remainder of this phase where the linen in the stationary state is soaked in this liquid. In the washing phase which follows the soaking phase, the laundry is subjected to continuous stirring at usual rates, from the start to the end of this phase. The mixing of the linen is represented by undulations, in a curve III of the attached drawing. Thus in the soaking phase t₀ t₂, the brewing of the laundry occupies part of the time t₀-t₁ and a rest imposed on this laundry extends between t₁ and t₂, and in the washing phase t₂-t, the brewing of the laundry occupies throughout this phase t₂-t.

Selon une autre caractéristique, dans la phase de trempage t₀-t₂ et une première partie t₂-t₃ de la phase de lavage t₂-t, un liquide commun de trempage et de lavage est admis dans le lave-linge jusqu'à un niveau intermédiaire N₁ (courbe I) et dans la deuxième partie t₃-t de la phase de lavage t₂-t, le liquide commun de trempage, de lavage est élevé jusqu'à un niveau maximal prédéterminé N₂.According to another characteristic, in the soaking phase t₀-t₂ and a first part t₂-t₃ of the washing phase t₂-t, a common soaking and washing liquid is admitted into the washing machine up to an intermediate level N₁ (curve I) and in the second part t₃-t of the washing phase t₂-t, the common soaking and washing liquid is raised to a predetermined maximum level N₂.

Ce mode de remplissage du lave-linge permet d'avoir un liquide de trempage et un liquide de lavage dans un début de la phase de lavage, fort en concentration en produit lessiviel qui exerce une puissante action sur des salissures et d'obtenir un excellent résultat de lavage sans que la température de ce liquide de trempage et de lavage soit portée à une valeur supérieure à 45°C.This washing machine filling mode makes it possible to have a soaking liquid and a washing liquid in the beginning of the washing phase, high in concentration of detergent which exerts a powerful action on dirt and to obtain an excellent washing result without the temperature of this soaking and washing liquid being raised to a value greater than 45 ° C.

Dans un tel lave-linge où la température de travail est inférieure ou égale à 45°C environ, un linge fragile sensible à la température et un linge solide résistant à celle-ci peuvent ètre indifféremment lavés, sans risque de dommage causé à ce linge.In such a washing machine where the working temperature is less than or equal to about 45 ° C, a fragile cloth sensitive to temperature and a solid cloth resistant to it can be indifferently washed, without risk of damage to this cloth. .

Des essais comparatifs de lavage d'un linge coton effectué avec un même produit lessiviel révèlent d'une façon inattendue qu'un résultat analogue de lavage est obtenu successivement dans un lave-linge mettant en oeuvre l'invention où la température du liquide de trempage et de lavage est à une valeur de 40°C environ, et dans un lave-linge connu où une phase de prélavage classique (rappelée dans des paragraphes précédents) est ajoutée à une phase de lavage, et dans la phase de lavage , la température du liquide de lavage est portée à une valeur de 60°C, et qu'en plus une consommation en lessive, en eau et en énergie de chauffage dans le lave-linge mettant en oeuvre l'invention est nettement inférieure à celle dans le lave-linge connu.Comparative tests of washing a cotton linen carried out with the same detergent unexpectedly reveal that a similar washing result is obtained successively in a washing machine implementing the invention where the temperature of the soaking and washing liquid is at a value of around 40 ° C., and in a known washing machine where a conventional prewash phase (recalled in previous paragraphs) is added to a washing phase, and in the washing phase, the temperature of the washing liquid is brought to a value of 60 ° C., and that in addition a consumption of detergent, water and heating energy in the washing machine implementing the invention is significantly lower than in the known washing machine.

Cet excellent résultat est probablement dû aux facteurs efficaces révèlés par l'invention à savoir une bonne concentration en produit lessiviel durant le trempage et une première partie de la phase de lavage obtenue par une dissolution de ce produit dans une quantité intermédiaire de liquide N₁ dans le lave-linge, une température modérée du liquide de trempage et de lavage, un mouvement réduit du linge durant le trempage.This excellent result is probably due to the effective factors revealed by the invention, namely a good concentration of detergent during soaking and a first part of the washing phase obtained by dissolving this product in an intermediate quantity of liquid N₁ in the washing machine, moderate temperature of the soaking and washing liquid, reduced movement of the laundry during soaking.

Dans une varlante (non représentée) de mise en oeuvre de l'invention, des durées de brassage du linge respectivement séparées par de plus longues périodes de repos du linge sont effectuées le long de la phase de trempage pour favoriser une bonne pénétration du liquide de trempage dans le linge et une uniformité de contact entre le liquide de trempage et la totalité de la surface de ce linge.In a variant (not shown) of implementation of the invention, times for stirring the laundry respectively separated by longer periods of rest of the laundry are carried out along the soaking phase to promote good penetration of the liquid of soaking in the laundry and uniformity of contact between the soaking liquid and the entire surface of this laundry.

Selon une autre variante de mise en oeuvre de l'invention, pour un lavage de linge résistant à la température, la température du liquide de trempage et du liquide de lavage est portée durant la phase de trempage (t₀-t₂) à une valeur entre 30°C et 45°C, et durant la phase de lavage (t₂-t) à une valeur entre 45°C et 90°C, l'action physico-chimique résiduelle du produit lessiviel utilisé dans le lave-linge, pouvant ainsi être pleinement développée. Un excellent résultat de lavage est alors obtenue.According to another alternative embodiment of the invention, for washing temperature-resistant laundry, the temperature of the soaking liquid and of the washing liquid is brought during the soaking phase (t₀-t₂) to a value between 30 ° C and 45 ° C, and during the washing phase (t₂-t) at a value between 45 ° C and 90 ° C, the residual physicochemical action of the detergent used in the washing machine, thus being able to be fully developed. An excellent washing result is then obtained.
