Description
L'invention concerne un procédé de lavage et de séchage du linge et son dispositif d'application.The invention relates to a method for washing and drying linen and its application device.
Il existe déjà des machines lavantes-séchantes, avec les-quelles les opérations de lavage s'effectuent selon le procédé classique d'introduction d'eau, additionnée ou non de produits lessiviels, dans une cuve, à l'intérieur de laquelle un tambour, dont la périphérie comporte de multiples perforations, est entraîné en rotation, et les opérations de séchage s'effectuent par introduction d'air chaud à l'intérieur de la cuve, avec échappement de celui-ci par un conduit diamétralement opposé, par rapport au tambour, à celui d'admission ; cet air pouvant être recyclé, après assèchement et réchauffage éventuels ; le tambour étant entraîné en rotation pendant ce temps.Washing-drying machines already exist, with which washing operations are carried out according to the conventional method of introducing water, with or without the addition of detergents, into a tank, inside which a drum , the periphery of which comprises multiple perforations, is driven in rotation, and the drying operations are carried out by introducing hot air inside the tank, with the latter escaping via a diametrically opposite duct, with respect to to the drum, to the intake drum; this air can be recycled, after drying and possible reheating; the drum being rotated during this time.
On comprend que, par ce moyen et selon ce procédé, le séchage soit long et exige une dépense d'énergie importante, compte-tenu principalement du fait que, la section des perforations du tambour étant bien inférieure aux passages extérieurs entre la cuve et le tambour, l'air a surtout tendance a passer autour de celui-ci.It is understood that, by this means and according to this method, the drying is long and requires a significant energy expenditure, taking into account mainly the fact that, the section of the perforations of the drum being much smaller than the external passages between the tank and the drum, air mostly tends to pass around it.
On connaît déjà une machine lavante-séchante, comportant un dispositif visant à favoriser l'introduction de l'air à l'intérieur du tambour, au voisinage de son axe de rotation, afin que celui-ci puisse traverser le linge de l'intérieur vers l'extérieur du tambour. Il s'agit d'une machine à chargement par l'avant, dont la cuve comporte, au voisinage ou dans la trappe de chargement, une buse, alimentée par un conduit disposé dans la face avant de la machine. Ceci améliore considérablement l'échange air-linge et, par conséquent, les performances, sous réserve que la face concernée du tambour soit munie de perforations adéquates et que le jet d'air soit correctement dirigé.A washer-dryer machine is already known, comprising a device for promoting the introduction of air inside the drum, in the vicinity of its axis of rotation, so that it can pass through the laundry from the inside. outward from the drum. It is a front-loading machine, the tank of which comprises, in the vicinity or in the loading hatch, a nozzle, supplied by a duct arranged in the front face of the machine. This considerably improves the air-linen exchange and, consequently, performance, provided that the relevant face of the drum is provided with adequate perforations and that the air jet is correctly directed.
Cependant, comme on vient de le voir, un tel dispositif ne s'applique qu'aux machines lavantes-séchantes à chargement par l'avant, et ne concerne que la phase de séchage.However, as we have just seen, such a device only applies to front-loading washing-drying machines, and only concerns the drying phase.
Le procédé et le dispositif selon l'invention visent à remédier aux inconvénients cités ci-dessus. Cette invention, telle qu'elle se caractérise, résout donc le problème consistant à définir un procédé et à réaliser un dispositif avec lesquels le liquide de lavage et l'air de séchage soient introduits en totalité, ou en très grande partie, au niveau de l'axe de rotation du tambour et ressortent par les perforations existantes à la périphérie du tambour, après avoir été directement en contact avec le linge ; ceci sans que l'architecture traditionnelle de la machine soit fondamentalement remise en question.The method and the device according to the invention aim to remedy the drawbacks mentioned above. This invention, as it is characterized, therefore solves the problem of defining a method and producing a device with which the washing liquid and the drying air are introduced in whole, or in large part, at the level of the axis of rotation of the drum and emerge through the perforations existing at the periphery of the drum, after having been in direct contact with the laundry; this without the traditional architecture of the machine being fundamentally questioned.
Le procédé de lavage et de séchage de linge selon l'invention consiste à :
- faire circuler l'eau de lavage ou de rinçage et l'air de séchage radialement dans le tambour,
- introduire le produit assouplissant lors du dernier rinçage, se caractérise principalement en ce qu'il
- effectue ce dernier rinçage à chaud,
- essore le linge,ainsi imbibé d'une solution de produit assouplissant chaud,
- réalise le séchage pendant un temps déterminé en fonction du degré de séchage que l'on désire obtenir (linge rangeable ou repassable),
- effectue le débourrage du circuit extérieur de séchage juste avant la fin de l'opération de séchage.
- circulate the washing or rinsing water and the drying air radially in the drum,
- introduce the softener during the last rinse, is mainly characterized in that it
- performs this last hot rinse,
- spin the laundry, soaked in a solution of hot fabric softener,
- performs the drying for a determined time depending on the degree of drying that one wishes to obtain (tidy or ironable laundry),
- clears the external drying circuit just before the end of the drying operation.
Selon une définition particulière et préférentielle du procédé, l'eau de lavage ou de rinçage et l'air de séchage circulent de l'axe du tambour vers la périphérie de celui-ci.According to a particular and preferential definition of the process, the washing or rinsing water and the drying air circulate from the axis of the drum towards the periphery thereof.
Selon une autre définition particulière du procédé, l'eau de lavage ou de rinçage circule de l'axe du tambour vers la périphérie de celui-ci, alors que l'air de séchage circule dans le sens inverse.According to another particular definition of the process, the washing or rinsing water circulates from the axis of the drum towards the periphery thereof, while the drying air circulates in the opposite direction.
Le dispositif d'application du procédé selon l'invention dans lequel la circulation de l'eau de lavage ou de rinçage et de l'air de séchage s'effectuent à travers l'arbre du tambour ; et les produits lessiviels et assouplissants sont introduits dans la veine d'eau, en amont du tambour ; et le liquide de lavage ou de rinçage est chauffé par circulation en circuit fermé, à travers une batterie d'éléments chauffants ; se caractérise principalement en ce que la durée du séchage est déterminée, par le programmateur de la machine, en fonction de l'hygrométrie de l'air s'échappant du tambour et de la température qui est fonction de la nature des fibres, et en ce que le débourrage du circuit de séchage s'effectue par l'intermédiaire d'un injecteur d'eau, monté dans la conduite d'air, en amont de la soufflante et au voisinage de l'axe de rotation de la turbine de celle-ci.The device for applying the method according to the invention in which the circulation of the washing or rinsing water and the drying air takes place through the shaft of the drum; and the detergents and softeners are introduced into the water stream, upstream of the drum; and the washing or rinsing liquid is heated by circulation in a closed circuit, through a battery of heating elements; is mainly characterized in that the duration of the drying is determined, by the programmer of the machine, as a function of the humidity of the air escaping from the drum and of the temperature which is a function of the nature of the fibers, and in that the cleaning of the drying circuit is carried out by means of a water injector, mounted in the air line, upstream of the blower and in the vicinity of the axis of rotation of the turbine from that -this.
L'eau de lavage ou de rinçage est introduite dans l'arbre creux du tambour par l'intermédiaire d'une buse, reliée à la crépine d'aspiration située dans le puisard de la cuve, par l'intermédiaire d'un conduit desservant une pompe, des éléments chauffants, une sonde thermométrique et un gicleur de dosage et d'introduction de produits lessiviels.The washing or rinsing water is introduced into the hollow shaft of the drum via a nozzle, connected to the suction strainer located in the sump of the tank, via a conduit serving a pump, heating elements, a temperature probe and a nozzle for dosing and introducing detergents.
L'arbre creux du tambour est mis en communication extérieurement avec la cuve, par l'intermédiaire d'un pot, entourant la buse d'introduction d'eau, et d'une conduite desservant une sonde hygrométrique, un injecteur d'eau, une soufflante, un condenseur, des éléments chauffants et une sonde thermométrique.The hollow shaft of the drum is placed in external communication with the tank, by means of a pot, surrounding the water introduction nozzle, and of a pipe. serving a hygrometric probe, a water injector, a blower, a condenser, heating elements and a thermometric probe.
L'arbre du tambour peut être prolongé, jusqu'à la paroi opposée dudit tambour, par un tube comportant de multiples perforations.The shaft of the drum can be extended to the opposite wall of said drum by a tube having multiple perforations.
Selon un mode de réalisation simplifié, l'arbre du tambour comporte, à sa sortie, vers l'intérieur du tambour, une pomme perforée.According to a simplified embodiment, the shaft of the drum comprises, at its outlet, towards the inside of the drum, a perforated apple.
Dans un cas comme dans l'autre, l'orifice d'entrée comporte une collerette entourant la buse d'introduction d'eau.In either case, the inlet has a flange surrounding the water introduction nozzle.
Les avantages obtenus, grâce à cette invention, consistent essentiellement en ceci qu'elle permet de rationaliser les quantités d'eau, de lessive, d'adoucisseur et d'énergie, avec optimisation de la température de chauffe et du temps nécessaire à l'obtention du degré de séchage désiré, selon que l'on souhaite disposer de linge rangeable ou repassable, tout en se prêtant à une auto-adaptation totale du processus à la charge de linge.The advantages obtained, thanks to this invention, consist essentially in that it makes it possible to rationalize the quantities of water, detergent, softener and energy, with optimization of the heating temperature and the time necessary for the obtaining the desired degree of drying, depending on whether one wishes to have clothes that can be stored or ironed, while allowing a total self-adaptation of the process to the load of laundry.
D'autres caractéristiques et avantages apparaîtront dans la description qui va suivre des deux modes de réalisation du dispositif selon l'invention et de leur mise en oeuvre selon la définition préférentielle du procédé faisant l'objet de la même invention, donnés à titre d'exemple non limitatif au regard des dessins annexés sur lesquels :
- la figure 1 représente une vue en coupe partielle du dispositif monté sur une machine lavante-séchante,
- la figure 2 représente une vue en coupe partielle d'un mode de réalisation simplifié de l'invention,
- la figure 3 représente le schéma de raccordement du dispositif aux circuits de fluide respectifs.
- FIG. 1 shows a partial section view of the device mounted on a washer-dryer machine,

- Figure 3 shows the connection diagram of the device to the respective fluid circuits.
Les figures représentent une machine à laver et à sécher le linge selon l'invention, dont l'un des côtés 11 du tambour 10, relié à la cuve 20 par l'intermédiaire d'un arbre creux 21 débouchant, vers l'extérieur, dans un pot 31 relié à la cuve par une conduite 30, desservant une sonde hygrométrique 32, un injecteur d'eau 33, une soufflante 34, un condenseur 35, un bloc d'éléments chauffants 36 et une sonde thermométrique 37, et, vers l'intérieur du tambour 10, par l'intermédiaire d'un tube 12, comportant de multiples perforations radiales 121, ou d'une pomme 13 à perforations 131, dont l'orifice d'entrée comporte une collerette 122 ou 132, entourant le bec d'une buse 41 d'introduction d'eau traversant le pot 31 ; la dite buse 41 étant reliée à la crépine d'aspiration 241, située dans le puisard 24 de la cuve 20, par un conduit 40 desservant une pompe 42, une batterie d'éléments chauffants 43, une sonde thermométrique 44 et un gicleur 45 d'introduction de produits lessiviels.The figures show a washing and drying machine according to the invention, one of the
En examinant maintenant plus en détail les figures 1 et 2, on remarque que l'eau de lavage et de rinçage et l'air de séchage sont introduits dans l'axe du tambour 10 et dirigés vers le centre de celui-ci par l'intermédiaire, respectivement, de la buse 41 ou du pot 31, ce qui permet d'appliquer le procédé selon l'invention, selon lequel l'eau de lavage ou de rinçage et l'air de séchage circulent radialement de l'axe du tambour 10 vers la périphérie de celui-ci, en traversant le linge. La collerette 122 ou 132 du tube 12, ou de la pomme perforée 13, s'oppose à tout écoulement parasite de liquide à l'intérieur du pot 31.Now examining Figures 1 and 2 in more detail, it can be seen that the washing and rinsing water and the drying air are introduced into the axis of the
Si l'on se reporte à la figure 3, on remarque que, sous réserve que les équipements 32 - 37, situés sur la conduite 30, et 42 - 45, situés sur le conduit 40, soient contrôlés par un programmateur, bien connu de l'homme de métier, il est possible d'appliquer automatiquement, au cours du processus de lavage et de séchage, le procédé selon l'invention dans son intégralité, c'est-à-dire faire circuler les fluides de lavage, de rinçage et de séchage à travers le tambour, en partant de l'axe pour aller vers la périphérie de celui-ci, d'introduire le produit assouplissant lors du dernier rinçage, d'effectuer ce dernier rinçage à une température parfaitement contrôlée, d'assurer l'essorage à une vitesse de rotation et pendant une durée déterminées et de réaliser le séchage pendant un temps et à une température déterminés en fonction de la nature des fibres textiles et du degré de séchage que l'on désire obtenir (linge rangeable ou repassable).Referring to FIG. 3, it is noted that, provided that the equipment 32 - 37, located on the
La réalisation d'un dernier rinçage à chaud, avec adjonction d'assouplissant, avant l'essorage, permet de rendre l'eau plus fluide au cours de celui-ci et d'obtenir, de ce fait, un essorage plus efficace dans le même temps et à la même vitesse. Cette opération pouvant être requise avant un séchage, afin d'en diminuer la durée, qui sera d'autant plus réduite que l'air chaud sera mêlé, plus intimement et dans sa total i té, au linge à sécher, qui est, pendant ce temps, soumis à des effets mécaniques dus à la rotation alternée du tambour.Carrying out a final hot rinse, with the addition of fabric softener, before spinning, makes the water more fluid during the latter and therefore achieves a more efficient spinning in the same time and at the same speed. This operation may be required before drying, in order to reduce the duration, which will be all the more reduced as the hot air is mixed, more intimately and in its totality, with the laundry to be dried, which is, during this time, subject to mechanical effects due to the alternating rotation of the drum.
Pendant la phase de séchage, de la bourre de textile peut se coller sur les aubes de la turbine de la soufflante. Aussi, un nettoyage de ces aubes peut être réalisé par une injection d'eau dans la veine d'aspiration, c'est-à-dire en amont de la soufflante, au voisinage de l'axe de rotation de la turbine de celle-ci.During the drying phase, textile flock can stick to the blades of the blower turbine. Also, these blades can be cleaned by injecting water into the suction stream, that is to say upstream of the fan, in the vicinity of the axis of rotation of the turbine of the latter. this.
Il faut souligner que, par l'utilisation du procédé et du dispositif selon l'invention, il est possible de réduire d'un quart la durée de séchage ainsi que la consommation d'électricité et d'eau, avec un meilleur contrôle du coefficient d'essorage. La gestion de l'ensemble des paramètres par un dispositif de contrôle et de programmation électronique permet d'optimiser les résultats en fonction de la charge de linge.It should be emphasized that, by using the method and the device according to the invention, it is possible to reduce the drying time as well as the consumption of electricity and water by a quarter, with better control of the coefficient spin. The management of all the parameters by an electronic control and programming device makes it possible to optimize the results according to the load of laundry.
Quant au dispositif d'application de la définition particulière du procédé, consistant à faire circuler l'air de séchage radialement, de la périphérie du tambour vers l'axe de celui-ci, alors que la circulation d'eau est maintenue dans le sens contraire, il se déduit aisément de celui décrit ci-dessus par simple inversion de l'ordre de montage des équipement 32 à 37 sur la conduite 30 reliant le pot 31 à la cuve 20, contrairement à celui indiqué sur la figure 3.As for the device for applying the particular definition of the process, consisting in circulating the drying air radially, from the periphery of the drum towards the axis thereof, while the circulation of water is maintained in the direction on the contrary, it is easily deduced from that described above by simple reversal of the order of assembly of the
Quel que soit le dispositif mis en oeuvre, celui-ci peut être aisément intégré à la cuve et à l'habillage de celle-ci, sans remettre en question l'encombrement de la machine.Whatever the device used, it can be easily integrated into the tank and the covering thereof, without questioning the size of the machine.
Le procédé et le dispositif selon l'invention sont destinés, principalement, à équiper des lavantes-séchantes ménagères, mais rien ne s'oppose à ce qu'ils soient utilisés sur des machines de professionnels, voire industrielles, sous réserve d'adaptations mineures.The method and the device according to the invention are intended, mainly, to equip household washer-dryers, but nothing prevents them from being used on professional or even industrial machines, subject to minor adaptations .
