Description

La présente invention concerne un sèche-linge à ouverture par le dessus.The present invention relates to a top opening dryer.

En général dans des sèche-linge, des améliorations ont été habituellement recherchées pour diminuer la durée du séchage, et la consommation en énergie, et réduire au minimum le degré de froissage des pièces de linge séché. Une courte durée du séchage et une faible consommation en énergie dépendent notamment d'une bonne exposition des pièces du linge à un courant d'air de séchage.In general in dryers, improvements have usually been sought to decrease the drying time, and energy consumption, and to minimize the degree of crumpling of the items of dried laundry. A short drying time and low energy consumption depend in particular on good exposure of the laundry items to a current of drying air.

Des solutions visant à créer un brassage du linge dans un tambour horizontal au cours d'un séchage sont connues. Les unes prévoient à la surface intérieure de la virole du tambour horizontal à linge des nervures transversales espacées, parallèles à l'axe de rotation de ce tambour. Les autres font appel à une formation sur la surface intérieure de la virole de ce tambour horizontal de nervures transversales espacées, obliques vis-à-vis de l'axe de rotation de ce tambour. Les nervures transversales parallèles à l'axe du tambour permettent lors d'une rotatlon de ce dernier d'entraîner des pièces du linge qui se trouvent dans une partie basse dans ce tambour, vers une partie haute, de les laisser tomber et de recommencer les mêmes opérations jusqu'à l'arrêt du séchage.Solutions aimed at creating a mixing of the laundry in a horizontal drum during drying are known. Some provide spaced transverse ribs, parallel to the axis of rotation of this drum, on the inner surface of the shell of the horizontal laundry drum. The others use a formation on the inner surface of the shell of this horizontal drum of spaced transverse ribs, oblique with respect to the axis of rotation of this drum. The transverse ribs parallel to the axis of the drum make it possible, during a rotatlon of the latter, to pull pieces of the laundry which are in a low part in this drum, towards a high part, to drop them and to start again the same operations until drying stops.

Le linge évolue ainsi dans le tambour suivant des plans sensiblement verticaux. Ces nervures transversales ne communiquent pratiquement pas au linge un mouvement suivant l'axe du tambour et le brassage du linge dans le tambour s'avère ainsi peu satisfaisant.The linen thus evolves in the drum along substantially vertical planes. These transverse ribs practically do not communicate to the laundry a movement along the axis of the drum and the mixing of the laundry in the drum thus proves unsatisfactory.

Par contre, des nervures transversales obliques vis-à-vis de l'axe du tambour constituent pour le linge, lors d'une rotation de ce tambour, des rampes de glissement qui le ramènent de l'une des extrémités vers l'autre extrémité de ce tambour et créent plutôt un tassement des pièces du linge à une des extrémités de ce tambour qu'un brassage uniforme de ce linge.On the other hand, oblique transverse ribs with respect to the axis of the drum constitute for the laundry, during a rotation of this drum, sliding ramps which bring it back from one end to the other end of this drum and create rather a compaction of the laundry items at one end of this drum than a uniform mixing of this laundry.

Ces solutions connues ne permettent pas ainsi d'atteindre l'objectif visé, celui d'une bonne exposition des pièces du linge à un courant d'air de séchage.These known solutions do not therefore achieve the objective, that of good exposure of the laundry items to a current of drying air.

Une autre solution connue vise à pallier le mauvais effet d'un tassement du linge à une des extrémités du tambour, rappelé dans un paragraphe précédent, en utilisant cette extrémité du tambour comme extrémité de l'arrivée de l'air de séchage afin de forcer cet air de séchage d'aller à l'encontre de cet amas de linge, et en donnant en outre au flasque de l'extrémité opposée de ce tambour, une forme sensiblement d'un tronc de cône en vue de converger au niveau de cette extrémité, l'air de séchage vers la zone axiale de ce tambour où se trouvent des pièces de linge qui s'apprêtent à être refoulées par les nervures transversales obliques.Another known solution aims to overcome the bad effect of packing the laundry at one end of the drum, mentioned in a previous paragraph, by using this end of the drum as the end of the drying air inlet in order to force this drying air to go against this pile of linen, and in addition giving the flange of the opposite end of this drum, a shape substantially of a truncated cone in order to converge at this end, the drying air towards the axial zone of this drum where there are pieces of laundry which are about to be forced back by the oblique transverse ribs.

Le mouvement continu de refoulement des pièces du linge vers une des extrémités du tambour accentue cependant le tassement du linge et empêche un large contact entre l'air de séchage et les pièces du linge.The continuous delivery movement of the laundry items to one end of the drum, however, increases the compaction of the laundry and prevents large contact between the drying air and the laundry items.

Cette solution connue se révèle de ce fait, inefficace aussi à réaliser une bonne exposition du linge à un courant d'air de séchage.This known solution therefore proves to be ineffective also in achieving good exposure of the laundry to a current of drying air.

Dans des sèche-linge connus une diminution du degré de froissage des pièces de linge séché est habituellement résolue par un arrêt du séchage, dans une phase finale de séchage, dès l'apparition dans le courant d'air sortant du tambour à linge, d'une température prédéterminée correspondante à une température d'air de fin de séchage.In known tumble dryers, a reduction in the degree of crumpling of the pieces of dried laundry is usually resolved by stopping the drying, in a final drying phase, as soon as the air stream exiting the laundry drum appears, d a predetermined temperature corresponding to an air temperature at the end of drying.

En effet, un séchage prolongé à une température d'air supérieure à la température d'air de fin de séchage augmente le degré de froissage du linge séché. Ce procédé de diminution du degré de froissage du linge séché donne des résultats satisfaisants quand le linge soumis au séchage comporte un seul type de linge. Ces résultats deviennent irréguliers quand le linge soumis au séchage résulte d'un mélange de plusieurs types de linge.Indeed, prolonged drying at an air temperature higher than the air temperature at the end of drying increases the degree of crumpling of the dried laundry. This method of reducing the degree of crumpling of the dried linen gives satisfactory results when the linen subjected to drying comprises only one type of laundry. These results become irregular when the laundry subjected to drying results from a mixture of several types of laundry.

La présente invention visant à éviter ces inconvénients, permet de réaliser un sèche-linge économique, efficace, effectuant un bon brassage du linge et donnant un linge séché avec un degré minimal de froissage.The present invention, aimed at avoiding these drawbacks, makes it possible to produce an economic, efficient dryer, effecting a good stirring of the linen and giving a dried linen with a minimum degree of crumpling.

Selon l'invention, un sèche-linge à ouverture par le dessus et à tambour horizontal à linge est caractérisé en ce que le tambour à linge comprend deux flasques qui remplissent, au cours d'un séchage d'un linge, simultanément plusieurs fonctions, à savoir celle de apliers ou supports pour la rotation de la virole de ce tambour, celle de passages pour l'air de séchage, celle de moyens de guldage et de correction du mouvement du linge dans ce tambour, celle de moyens de défroissage du linge, celle d'enveloppes de protection des dispositifs de chauffage et de ventilation.According to the invention, a dryer with top opening and horizontal laundry drum is characterized in that the laundry drum comprises two flanges which simultaneously, during drying of a laundry, perform several functions, namely that of apliers or supports for the rotation of the shell of this drum, that of passages for drying air, that of means for guiding and correcting the movement of the linen in this drum, that of means for smoothing the linen , that of protective covers for heating and ventilation devices.

Pour mieux faire comprendre l'invention on en décrit ci-après un exemple de réalisation schématiquement et partiellement illustré dans un dessin ci-annexé.To make the invention easier to understand, an exemplary embodiment of it is schematically and partially illustrated below in a drawing attached hereto.

Selon cet exemple, un sèche-linge 1 est un sèche-linge à ouverture par le dessus. Le sèche-linge 1 comprend une carrosserie 2, ayant dans le dessus, une ouverture 3 fermée par une porte 4, et un tambour à linge 5 ayant un axe horizontal et muni dans sa paroi latérale cylindrique, d'un portillon d'accès 10. Dans sa position haute, le portillon d'accès 10 est en alignement avec l'ouverture 3 et la porte 4, ce qui facilite le chargement et/ou le déchargement en linge du tambour 5.According to this example, a dryer 1 is a dryer with top opening. The dryer 1 comprises a body 2, having in the top, an opening 3 closed by a door 4, and a laundry drum 5 having a horizontal axis and provided in its cylindrical side wall, with an access door 10 In its high position, the access door 10 is in alignment with the opening 3 and the door 4, which facilitates the loading and / or unloading of the drum 5 in linen.

Selon l'invention, dans un sèche-linge le tambour à linge comprend deux flasques qui remplissent au cours d'un séchage d'un linge, simultanément plusieurs fonctions, à savoir celle de paliers ou supports pour la rotation de la virole de ce tambour, celle de passages pour l'air de séchage, celle de moyens de guldage et de correction du mouvement du linge dans le tambour, celle de moyens de défroissage du linge, celle d'enveloppes de protection des dispositifs de chauffage et de ventilation.According to the invention, in a tumble dryer the laundry drum comprises two flanges which during drying of a laundry simultaneously fulfill several functions, namely that of bearings or supports for the rotation of the shell of this drum , that of passages for drying air, that of means for guiding and correcting the movement of the linen in the drum, that of means for smoothing the linen, that protective covers for heating and ventilation devices.

Dans l'exemple illustré, le tambour horizontal à linge 5 du sèche-linge à ouverture par le dessus 1 comprend d'une part une virole cylindrique mobile 8 montée tournante librement suivant un axe horizontal 6 et pourvue sur sa surface intérieure d'au moins une nervure transversale 12 parallèle à cet axe horizontal 6, et d'autre part deux flasques fixes 14 et 15 qui supportent en rotation les deux extrémités de cette virole mobile 8.In the example illustrated, the horizontal laundry drum 5 of the top-opening dryer 1 comprises on the one hand a movable cylindrical shell 8 mounted to rotate freely along a horizontal axis 6 and provided on its internal surface with at least a transverse rib 12 parallel to this horizontal axis 6, and on the other hand two fixed flanges 14 and 15 which support in rotation the two ends of this movable ferrule 8.

L'un 14 de ces flasques fixes est relativement plat et l'autre 15 est bombé, en saillie axialement dans cette virole 8. Les flasques fixes 14 et 15 comprennent respectivement des portées cylindriques 17 et 18 en saillie sur leurs surfaces intérieures et qui servent de paliers ou de supports d'anneaux de glissement pour la rotation de la virole mobile 8. Les flasques fixes plat 14 et bombé 15 sont pourvus dans leurs surfaces, de perforations ou trous 20,21 servant de passages pour l'entrée et la sortie de l'air de séchage.One 14 of these fixed flanges is relatively flat and the other 15 is curved, projecting axially in this ferrule 8. The fixed flanges 14 and 15 respectively comprise cylindrical bearing surfaces 17 and 18 projecting on their internal surfaces and which serve bearings or sliding ring supports for the rotation of the movable shell 8. The fixed flat flanges 14 and convex 15 are provided in their surfaces with perforations or holes 20,21 serving as passages for entry and exit drying air.

Le flasque fixe bombé 15 est muni sur sa surface intérieure d'un filtre coaxial à bourre de linge 23 et d'une grille coaxiale de protection 24 lesquels contribuent à renforcer la forme bombée de ce flasque. Le flasque fixe plat 14, le flasque fixe bombé 15 et la virole cylindrique mobile 8 qui définissent un volume intérieur du tambour 5, asymétrique vis-à-vis d'un plan médian transversal 26, constituent dans leur combinaison lors d'une rotation de la virole mobile 8, des surfaces actives complémentaires qui communiquent au linge un mouvement complexe réallsant un bras sage soigneux et uniforme du linge. Quand la virole mobile 8 tourne, la ou les nervures transversales 12 entraîne(nt) les pièces du linge de bas en haut, suivant des plans sensiblement verticaux jusqu'à une certaine hauteur dans ce tambour où ces pièces de linge par leurs poids glissent et retombent vers le bas. Cependant, certaines pièces ou parties de ces pièces de linge en mouvement qui évoluent dans la proximité des flasques fixes 14,15 sont diversement freinées dans leur ascension ou leur chute par leur contact avec ces flasques immobiles et repoussées axialement plus ou moins par ces flasques selon que la forme de ces derniers est bombée ou plate.The curved fixed flange 15 is provided on its inner surface with a coaxial filter with a flock of linen 23 and a coaxial protective grid 24 which contribute to reinforcing the curved shape of this flange. The flat fixed flange 14, the domed fixed flange 15 and the movable cylindrical shell 8 which define an internal volume of the drum 5, asymmetrical with respect to a transverse median plane 26, constitute in their combination during a rotation of the movable ferrule 8, complementary active surfaces which communicate to the linen a complex movement realling a careful and uniform wise arm of the linen. When the movable ferrule 8 rotates, the transverse rib or ribs 12 drive (s) the laundry items from bottom to top, in substantially vertical planes up to a certain height in this drum where these laundry items by their weight slide and fall back down. However, some parts or parts of these moving laundry items which evolve in the proximity of the fixed flanges 14,15 are variously braked in their ascent or fall by their contact with these immobile flanges and axially repelled more or less by these flanges depending on whether the shape of the latter is curved or flat.

Il en résulte une action variée et multiple de guidage et de correction exercée par ces flasques sur le mouvement d'ascension sensiblement verticale et de chute du linge entraîné par la ou les nervures transversales 12 de la virole mobile 8 en rotation.This results in a varied and multiple guide and correction action exerted by these flanges on the substantially vertical ascent and fall movement of the laundry driven by the transverse rib (s) 12 of the rotating ferrule 8 in rotation.

Dans l'exemple illustré, un dispositif électrique chauffant 28 est monté dans l'espace entre la carrosserie 2 et le tambour à linge 5, à proximité du flasque fixe plat 14 et déployé régulièrement le long de la surface de ce dernier pour a la fois chauffer l'air de séchage, indiqué par des flèches 30,31, avant son entrée dans le tambour à linge 5, et porter la surface de ce flasque fixe 14 à une température uniforme préétablie qui produit un effet de repassage ou défroissage aux pièces de linge en frottement contre cette surface. Le flasque fixe plat 14 forme avec la paroi 37 de la carrosserie 2 adjacente et le dispositif chauffant 28, une gaine d'entrée et de chauffage 38 de l'air de séchage. Le flasque fixe plat 14 constitue ainsi à la fois un moyen efficace de défroissage du linge et une enveloppe de protection de ce dispositif électrique chauffant 28. Un réflecteur 29 est monté entre la carrosserie 2 et le dispositif chauffant 28 pour réduire au minimum les pertes thermiques par conduction à travers la carrosserie 2.In the example illustrated, an electric heating device 28 is mounted in the space between the body 2 and the laundry drum 5, near the flat fixed flange 14 and deployed regularly along the surface of the latter for both heating the drying air, indicated by arrows 30, 31, before entering the laundry drum 5, and bringing the surface of this fixed flange 14 to a preset uniform temperature which produces an ironing or smoothing effect on the pieces of laundry rubbing against this surface. The fixed fixed flange 14 forms, with the wall 37 of the adjacent body 2 and the heating device 28, an inlet and heating sheath 38 for the drying air. The fixed flat flange 14 thus constitutes both an effective means of smoothing the linen and a protective envelope for this electric heating device 28. A reflector 29 is mounted between the body 2 and the heating device 28 to minimize heat losses by conduction through the body 2.

Un dispositif de ventilation 32 est monté dans l'espace entre la carrosserie 2 et le tambour 5, à proximité du flasque fixe bombé 15, coaxialement avec ce flasque pour créer par aspiration, un courant d'air de séchage 34,35 à travers le tambour à linge 5. Le flasque fixe bombé 15 forme avec un contre-flasque 39 et le dispositif de ventilation 32, une gaine de sortie d'air de séchage 40 et une enveloppe de protection de ce dispositif de ventilation 32.A ventilation device 32 is mounted in the space between the body 2 and the drum 5, near the domed fixed flange 15, coaxially with this flange to create by suction, a current of drying air 34.35 through the laundry drum 5. The domed fixed flange 15 forms with a counterflange 39 and the ventilation device 32, a drying air outlet duct 40 and a protective casing for this ventilation device 32.

Dans l'exemple illustré la virole mobile 8 et le dispositif de ventilation 32 sont respectivement entraînés à travers des courroies de transmission 41 et 36 par un moteur électrique 33.In the example illustrated, the movable ferrule 8 and the ventilation device 32 are respectively driven through transmission belts 41 and 36 by an electric motor 33.

Dans un sèche-linge connu du type à ouverture par le dessus, le tambour horizontal à linge tournant autour d'un axe horizontal est généralement un récipient cylindrique dont la virole et les flasques d'extrémité sont normalement assemblés et fixés par soudage ou sertissage. Cette structure habituelle du tambour à linge est simple et facile à réaliser.In a known dryer of the top opening type, the horizontal laundry drum rotating around a horizontal axis is generally a cylindrical container whose ferrule and end flanges are normally assembled and fixed by welding or crimping. This usual structure of the laundry drum is simple and easy to make.

Cependant dans un tel tambour, le mouvement du linge est celui entraîné par une ou plusieurs nervures transversales espacées formées sur la surface intérieure de ce tambour et les flasques qui tournent avec la virole du tambour ne produisent pratiquement ni action sur le mouvement de ce linge dans le tambour ni effet particulier sur le degré de froissage de ce linge.However in such a drum, the movement of the laundry is that driven by one or more spaced transverse ribs formed on the inner surface of this drum and the flanges which rotate with the shell of the drum have practically no effect on the movement of this laundry in the drum nor any particular effect on the degree of wrinkling of this linen.

Grâce à une structure particulière et nouvelle du tambour à linge, apportée par l'invention, le sèche-linge 1 à ouverture par le dessus décrit dans les paragraphes précédents réalise, par contre, d'excellentes performances en comparaison avec celles des sèche-linge connus du même type. Ces bonnes performances se traduisent dans le sèche-linge 1 par une forte réduction du temps de séchage et de la consommation en énergie, nécessaires à l'obtention d'un degré choisi de séchage du linge et par un résultat surprenant de défroissage du linge séché.Thanks to a particular and new structure of the laundry drum, provided by the invention, the dryer 1 with opening from above described in the preceding paragraphs achieves, on the other hand, excellent performances in comparison with those of the dryers known of the same type. These good performances are reflected in the dryer 1 by a great reduction in the drying time and in the energy consumption, necessary to obtain a selected degree of drying of the linen and by a surprising result of smoothing the dried linen. .
