Abstract

During its drying cycle the drum (2) of the machine (1)rotates at a speed which is lower than the spin speed but higher than the normal drying speed, so that the washing is distributed round the outside of the drum and does not impede the flow of drying air fed into its centre. The speed of the drum during the drying cycle can be between 65 and 70 rpm, or between 35 and 100 rpm, and the drying programme can include several different speed stages, with the drum rotated in the opposite direction in each new stage.

Description

La présente invention a pour objet un procédé de séchage amélioré du linge et une machine le mettant en oeuvre.The subject of the present invention is an improved method of drying linen and a machine using it.

Dans la plupart des machines lavantes-séchantes ou séchantes actuelles, l'air chaud est injecté au centre du tambour et doit sortir par la périphérie de ce tambour. Cependant, assez souvent, le linge s'agglomère en un tas qui obture le centre du tambour pendant la phase de séchage, empêchant ainsi l'entrée normale de l'air chaud dans le tambour, ainsi que l'évacuation correcte de l'air chaud ayant pu pénétrer dans le centre du tambour, et qui passe par un "court-circuit", c'est à dire sort aussitôt du tambour en traversant le minimum de linge.In most current washer-dryer or drying machines, hot air is injected into the center of the drum and must exit through the periphery of this drum. However, quite often, the laundry aggregates into a pile which closes the center of the drum during the drying phase, thus preventing the normal entry of hot air into the drum, as well as the correct evacuation of air. hot having been able to penetrate into the center of the drum, and which goes through a "short circuit", that is to say immediately leaves the drum by crossing the minimum of linen.

La présente invention a pour objet un procédé permettant d'améliorer le séchage du linge d'une machine lavante-séchante ou séchante, en diminuant, à efficacité égale, le temps de séchage, et ce, le plus simplement possible. La présente invention a également pour objet une machine mettant en oeuvre le procédé de l'invention.The subject of the present invention is a method making it possible to improve the drying of the linen of a washer-dryer or drying machine, by reducing, at equal efficiency, the drying time, and this, as simply as possible. The present invention also relates to a machine implementing the method of the invention.

Le procédé de l'invention consiste, en phase de séchage du linge, à faire tourner le tambour à une vitesse "de séchage amélioré" légèrement inférieure à la vitesse de centrifugation de son contenu. De façon avantageuse, cette vitesse est comprise entre 65 et 70 tours/mm environ.The method of the invention consists, in the drying phase of the laundry, of rotating the drum at an "improved drying" speed slightly lower than the speed of centrifugation of its contents. Advantageously, this speed is between 65 and 70 revolutions / mm approximately.

Selon un aspect avantageux du procédé de l'invention, la phase de séchage comporte plusieurs étapes, pendant chacune desquelles la vitesse de rotation du tambour est différente d'une étape à la suivante, avantageusement en alternant des étapes à vitesse supérieure, à vitesse égale et à vitesse inférieure à la vitesse de "séchage amélioré". Dans une même étape de séchage, la vitesse peut varier, par exemple, d'une vitesse minimale d'environ 35 à 50 t/mm à une vitesse maximale d'environ 70 à 100 t/mm.According to an advantageous aspect of the process of the invention, the drying phase comprises several stages, during each of which the speed of rotation of the drum is different from one stage to the next, advantageously by alternating stages at higher speed, at equal speed and at a speed lower than the speed of "improved drying". In the same drying step, the speed can vary, for example, from a minimum speed of approximately 35 to 50 t / mm to a maximum speed of approximately 70 to 100 t / mm.

La présente invention sera mieux comprise à la lecture de la description détaillée d'un mode de réalisation, pris à titre d'exemple non limitatif et illustré par le dessin annexé, sur lequel :

  • les figures 1 et 2 sont respectivement une vue schématisée de côté et une vue schématisée de dessus d'une machine lavante-séchante de l'art antérieur en phase de séchage de linge, et
  • les figures 3 et 4 sont respectivement une vue schématisée de côté et une vue schématisée de dessus d'une machine lavante-séchante conforme à l'invention, en phase de séchage de linge.
The present invention will be better understood on reading the detailed description of an embodiment, taken by way of nonlimiting example and illustrated by the appended drawing, in which:
  • FIGS. 1 and 2 are respectively a schematic side view and a schematic top view of a washer-dryer machine of the prior art in the laundry drying phase, and
  • Figures 3 and 4 are respectively a schematic side view and a schematic top view of a washer-dryer machine according to the invention, in the laundry drying phase.

La présente invention se rapporte aussi bien aux machines lavantes-séchantes qu'aux machines seulement séchantes, ces machines pouvant être à chargement frontal ou à chargement par le dessus. Pour simplifier, dans la suite de la description, on les qualifiera uniquement de machines.The present invention relates to washing-drying machines as well as to only drying machines, these machines possibly being front-loading or top-loading. To simplify, in the following description, they will only be called machines.

La machine 1, représentée en figures 1 et 2, comporte, entre autres, un tambour 2 tournant autour de son axe 3 dans une cuve 4. Le circuit de brassage d'air chaud de la machine 1 comporte une turbine 5 dont la conduite d'aspiration d'air 6 est reliée à la partie supérieure de la cuve 4, et dont la conduite d'injection d'air 7 est reliée à la cuve, coaxialement à l'axe 3. Pour simplifier le dessin, les autres parties du circuit de brassage d'air chaud (éléments chauffants et condenseur) n'ont pas été représentés.The machine 1, represented in FIGS. 1 and 2, comprises, inter alia, a drum 2 rotating around its axis 3 in a tank 4. The hot air mixing circuit of the machine 1 comprises a turbine 5 whose pipe d air intake 6 is connected to the upper part of the tank 4, and whose air injection pipe 7 is connected to the tank, coaxially with the axis 3. To simplify the drawing, the other parts of the hot air circulation circuit (heating elements and condenser) have not been shown.

Dans une machine de l'art antérieur (figures 1 et 2), le tambour tourne, en régime de séchage, à la même vitesse qu'en régime de lavage ou de rinçage (dans le cas d'une machine lavante), ce qui permet de simplifier la commande du moteur d'entraînement du tambour. Ceci a pour effet, lorsque la quantité de linge à sécher est telle que ce linge remplit au moins la moitié du tambour (à l'arrêt du celui-ci), de rassembler le linge 8 en une masse relativement compacte qui obstrue au moins partiellement la conduite d'injection d'air chaud 7. Il en résulte que l'air chaud arrivant par la conduite 7 dans le tambour suit un trajet de "court-circuit" entre la conduite 7 et la conduite 6, c'est à dire qu'il longe la paroi latérale du tambour 2 proche de la conduite 7 en traversant à peine le linge 8 qui est trop tassé pour offrir un passage à cet air chaud.In a machine of the prior art (FIGS. 1 and 2), the drum rotates, in drying mode, at the same speed as in washing or rinsing mode (in the case of a washing machine), which simplifies the control of the drum drive motor. This has the effect, when the quantity of laundry to be dried is such that this laundry fills at least half of the drum (when the latter is stopped), to gather the laundry 8 into a relatively compact mass which at least partially clogs the hot air injection pipe 7. As a result, the hot air arriving through the pipe 7 in the drum follows a "short-circuit" path between the pipe 7 and the pipe 6, that is to say that it runs along the side wall of the drum 2 close to the pipe 7, barely crossing the linen 8 which is too compacted to provide passage for this hot air.

Par contre, grâce au procédé de l'invention, (figures 3 et 4) selon lequel on fait tourner le tambour, en phase de séchage, à une vitesse de "séchage amélioré" inférieure à la vitesse de centrifugation de son contenu, fonction du diamètre du tambour, typiquement d'environ 65 à 70 t/mm, on répartit sensiblement uniformément le linge 8' en couronne autour d'un "tuyau" central 9 vide de linge, qui constitue le prolongement de la conduite 7. L'air chaud passe naturellement dans ce tuyau 9 et traverse le linge 8' dans tout son volume, puisque celui-ci, du fait qu'il est beaucoup moins tassé que dans le cas précédent (figures 1 et 2), offre relativement peu de résistance au passage de l'air chaud. En outre, du fait qu'il est moins tassé, le linge est moins froissé après séchage. Le "tuyau" 9 a un diamètre qui dépend de la vitesse de rotation du tambour, et qui est égal ou légèrement supérieur au diamètre de la conduite 7. Ainsi, par rapport à l'art antérieur, on améliore le séchage du linge et on diminue le temps de séchage à degré de séchage égal, et par conséquent on diminue aussi la consommation en énergie électrique. De plus, les pièces de linge se trouvant près du tuyau 9 sont beaucoup moins sujettes à la force centrifuge que celles qui sont les plus éloignées de ce tuyau, et peuvent se déplacer par rapport aux autres pièces de linge, en migrant de l'axe vers la périphérie du tambour, assurant ainsi un brassage de linge et améliorant l'homogénéité du séchage.On the other hand, thanks to the process of the invention (FIGS. 3 and 4) according to which the drum is rotated, in the drying phase, at a speed of "improved drying" lower than the speed of centrifugation of its content, depending on the diameter of the drum, typically about 65 to 70 t / mm, the linen 8 ′ is distributed in a uniform manner around a central "pipe" 9 empty of linen, which constitutes the extension of the pipe 7. The hot air naturally passes through this pipe 9 and passes through the linen 8 'in all its volume, since the latter, because it is much less packed than in the previous case (Figures 1 and 2), offers relatively little resistance to the passage of hot air. In addition, because it is less packed, the laundry is less wrinkled after drying. The "pipe" 9 has a diameter which depends on the speed of rotation of the drum, and which is equal to or slightly greater than the diameter of the pipe 7. Thus, compared with the prior art, the drying of the laundry is improved and decreases the drying time for an equal degree of drying, and therefore the consumption of electrical energy is also reduced. In addition, the pieces of laundry near the pipe 9 are much less subject to centrifugal force than those that are furthest from this pipe, and can move relative to other pieces of laundry, migrating from the axis towards the periphery of the drum, thus ensuring a mixing of laundry and improving the uniformity of drying.

Selon un aspect avantageux du procédé de l'invention, la vitesse de rotation du tambour en régime de séchage n'est pas maintenue constante. Elle peut varier par paliers ou progressivement autour de la vitesse de séchage amélioré, entre deux limites qui sont par exemple 35 t/mm et 100 t/mm environ, et peut alternativement augmenter et diminuer entre ces deux limites. On peut avantageusement prévoir de courtes pauses durant la phase de séchage, permettant au linge de retomber au fond du tambour à l'arrêt de celui-ci, et de se répartir différemment lorsque le tambour reprend sa rotation. Les différents paliers de vitesse ou les différentes vitesses de rotation du tambour peuvent correspondre à différentes étapes de séchage du linge : début, milieu et fin du séchage, et refroidissement du linge. A chaque arrêt, le tambour peut changer de sens de rotation, de manière à ne pas emmêler le linge, à favoriser l'homogénéité du séchage et à limiter le froissage de ce linge.According to an advantageous aspect of the process of the invention, the speed of rotation of the drum in the drying regime is not kept constant. It can vary in stages or gradually around the improved drying speed, between two limits which are for example 35 t / mm and about 100 t / mm, and can alternately increase and decrease between these two limits. Advantageously, short breaks can be provided during the drying phase, allowing the laundry to fall to the bottom of the drum when it stops, and to be distributed differently when the drum resumes its rotation. The different speed levels or the different rotation speeds of the drum can correspond to different stages of drying of the laundry: start, middle and end of drying, and cooling of the laundry. At each stop, the drum can change the direction of rotation, so as not to tangle the laundry, to promote uniformity of drying and to limit wrinkling of this laundry.
