Description
L'invention concerne un procédé et un dispositif d'élimination des dépôts de bourre dans le circuit de production d'air chaud des machines à laver et à sécher le linge.The invention relates to a method and a device for removing fluff deposits in the hot air production circuit of washing and drying machines.
Les machines à laver et à sécher le linge, ainsi que les sèche-linges, proposés actuellement sur le marché, sont généralement équipés d'un filtre à bourre, destiné à retenir une proportion très importante des fragments de fibres textiles libérés par le linge au cours des opérations de séchage ; ceci dans le but de retarder le développement de dépôt de bourre dans le circuit d'air de séchage, afin d'éviter, par exemple, que ceux-ci ne finissent par réduire les sections de passage et le rendement aérodynamique de la soufflante, ainsi que l'efficacité des sondes par "capitonnage" de leur bulbe.Washing and drying machines, as well as dryers, currently available on the market, are generally equipped with a fluff filter, intended to retain a very large proportion of the fragments of textile fibers released by the linen during during drying operations; this in order to delay the development of lint deposit in the drying air circuit, in order to avoid, for example, that these will ultimately reduce the flow sections and the aerodynamic efficiency of the blower, as well that the effectiveness of the probes by "padding" of their bulb.
Toutefois, ces filtres se colmatent très rapidement, ce qui crée une perte de charge très importante sur le circuit d'air, qui nécessite que ce filtre soit nettoyé après chaque utilisation de la machine, en recourant à une brosse spéciale, combinée au filtre, ou à un jet d'air à contre-courant.However, these filters clog up very quickly, which creates a very significant pressure drop on the air circuit, which requires that this filter be cleaned after each use of the machine, using a special brush, combined with the filter, or a jet of air against the current.
Ces solutions compliquent la machine et exigent une opération manuelle volontaire après chaque utilisation qui, en cas d'omission, risque de compromettre le résultat de l'opération de séchage suivante, voire le fonctionnement de la machine elle-même.These solutions complicate the machine and require a voluntary manual operation after each use which, if omitted, risks compromising the result of the next drying operation, or even the operation of the machine itself.
Il existe des machines non équipées de filtre sur lesquelles, au fur et à mesure des cycles de lavage, des particules de bourre se déposent sur les éléments du circuit de séchage, en particulier sur le ventilateur, les éléments chauffants et les dispositifs de régulation de température ; ce qui entraîne des baisses de performance progressives et provoque des risques d'incendie.There are machines without filters on which, during the washing cycles, fluff particles are deposited on the elements of the drying circuit, in particular on the fan, the heating elements and the regulation devices of temperature ; which results in gradual performance reductions and risks of fire.
On connaît déjà une machine à sécher et à laver le linge, munie d'un filtre à bourre n'exigeant aucun nettoiement ni évacuation de la bourre collectée (demande de brevet d'invention français n° 2.646.444). Les mailles du filtre laissent passer de petites particules de bourre de linge et sa forme saillante, vers l'intérieur du tambour, favorise, durant le séchage, un contact suivi et volontaire avec le linge en mouvement dans ce tambour, ce qui provoque un nettoiement de la surface du filtre et une fragmentation volontaire et répétée de la bourre retenue par celui-ci.There is already known a machine for drying and washing clothes, provided with a fluff filter requiring no cleaning or evacuation of the collected flock (French patent application No. 2,646,444). The mesh of the filter lets pass small particles of linen fluff and its protruding shape, towards the inside of the drum, promotes, during drying, a continuous and voluntary contact with the linen moving in this drum, which causes a cleaning. of the surface of the filter and a voluntary and repeated fragmentation of the fluff retained by it.
On connaît aussi une machine à sécher et à laver le linge, munie d'un filtre à bourre n'exigeant aucun nettoiement, ni évacuation de la bourre collectée en recourant à deux niveaux d'eau (brevet US-A-3.111.018). La bourre retenue dans le circuit d'air chaud est simplement baignée sans être soumise à une action dynamique susceptible de provoquer le décollement et l'évacuation des particules les plus accrochées.There is also known a machine for drying and washing clothes, provided with a fluff filter requiring no cleaning, nor evacuation of the collected fluff by using two levels of water (US-A-3,111,018 patent) . The wad retained in the hot air circuit is simply bathed without being subjected to a dynamic action capable of causing the detachment and the evacuation of the most attached particles.
Dans les deux cas, si le nettoiement du filtre et le colmatage de celui-ci sont évités, il n'en demeure pas moins que les dépôts de bourre, en certains points du circuit de production d'air chaud, subsistent toujours, étant donné le recyclage induit de l'air humide évacué.In both cases, if cleaning of the filter and clogging of the filter are avoided, the fact remains that the fluff deposits, at certain points in the hot air production circuit, still remain, given recycling induces exhausted humid air.
La présente invention a pour but de remédier à ces inconvénients. Cette invention, telle qu'elle est caractérisée dans les revendications, résout le problème consistant à définir un procédé et à créer un dispositif permettant, sur une machine à laver et à sécher le linge, d'utiliser certaines étapes du cycle de lavage pour décoller les dépôts de bourre, les fractionner et les évacuer, afin que le circuit de production d'air chaud en soit débarrassé lors de l'opération de séchage qui suit, ceci sans qu'aucune intervention manuelle soit nécessaire, par incorporation de la ou des opérations d'élimination de bourre dans le programme gérant le fonctionnement de la machine.The object of the present invention is to remedy these drawbacks. This invention, as characterized in the claims, solves the problem of defining a method and to create a device making it possible, on a washing machine and to dry the linen, to use certain stages of the washing cycle to take off the deposits of fluff, to fractionate and evacuate them, so that the hot air production circuit is removed during the following drying operation, without any manual intervention being necessary, by incorporating the flock removal operation (s) into the program managing the operation of the machine.
Dans le dispositif d'application du procédé la mise en concordance des niveaux de liquide dans la cuve de lavage et de séchage et dans le circuit de production d'air chaud est obtenue par l'intermédiaire d'une conduite reliant le point le plus bas de la cuve à celui du circuit de production d'air chaud.In the device for applying the process, the levels of liquid in the washing and drying tank and in the hot air production circuit are brought into line by means of a line connecting the lowest point. from the tank to that of the hot air production circuit.
L'élimination de la bourre s'effectue par l'intermédiaire d'une tuyauterie de vidange reliée au point le plus bas de la conduite de mise en communication de la cuve avec le circuit de production d'air chaud.The fluff is removed by means of a drainage pipe connected to the lowest point of the pipe for placing the tank in communication with the hot air production circuit.
Selon un mode de réalisation particulier de l'invention, la conduite de mise en communication de la cuve de lavage et de séchage avec le circuit de production d'air chaud peut être obturée à volonté par une vanne pilotée située entre le point de raccordement de la tuyauterie de vidange et le circuit de production d'air chaud ; la fermeture de la vanne étant, dans ce cas, asservie à un détecteur du niveau dans le dit circuit de production d'air chaud, sous contrôle du programmateur de la machine.According to a particular embodiment of the invention, the pipe for placing the washing and drying tank in communication with the hot air production circuit can be closed at will by a piloted valve located between the connection point of the drain piping and the hot air production circuit; the closure of the valve being, in this case, controlled by a level detector in the said hot air production circuit, under the control of the programmer of the machine.
Les avantages obtenus, grâce à cette invention consistent essentiellement en ceci que la bourre produite lors de l'opération de séchage précédente est systématiquement éliminée lors des opérations de lavage suivantes, sans que cela tasse appel à l'initiative de l'utilisateur, et sans que cela exige l'adjonction de dispositifs coûteux.The advantages obtained, thanks to this invention essentially consist in the fact that the fluff produced during the previous drying operation is systematically eliminated during the following washing operations, without this calling for the initiative of the user, and without that this requires the addition of expensive devices.
D'autres caractéristiques et avantages apparaîtront dans la description qui va suivre d'un dispositif d'élimination de bourre, réalisé selon l'invention pour les besoins d'une machine à laver et à sécher le linge, à introduction d'air et d'eau par l'arbre d'entraînement du tambour, telle que décrite dans la demande de brevet français n° 9013819 donné à titre d'exemple non limitatif au regard des dessins annexés sur lesquels :
- la figure 1 représente une vue de l'arrière, en coupe, du circuit de production d'air chaud équipé du dispositif d'élimination de bourre,
- la figure 2 représente une vue de côté schématique, en coupe, de la machine équipée du dispositif d'élimination de bourre.
- FIG. 1 represents a rear view, in section, of the hot air production circuit equipped with the fluff elimination device,
- 2 shows a schematic side view, in section, of the machine equipped with the fluff removal device.
Les figures représentent une machine à laver et à sécher le linge, à introduction d'air et d'eau par l'arbre creux d'entraînement 110 du tambour 120 monté dans la cuve 100, comportant, sur l'arrière, une double cloison 200, contenant une soufflante 210 à volute 211 reliée par un conduit 220 à une chambre de chauffage 230 munie d'éléments chauffants 231, d'une sonde de température 232, alimentant, par l'intermédiaire d'un carter 240, l'arbre creux d'entraînement 110 du tambour 120 ; le conduit 220 reliant la volute 211 de la soufflante 210 à la chambre de chauffage 230 étant relié par une conduite 30 à la cuve 100, avec raccordement à la tuyauterie de vidange 40.The figures show a washing machine and dryer, introducing air and water through the
En examinant plus en détail les figures 1 et 2, on remarque qu'il suffit de remplir la cuve 100 jusqu'à une hauteur (H) déterminée en fonction de la hauteur manométrique (hm) de la soufflante 210 et de la dénivellation (D) de la paroi supérieure 221 du conduit 220 par rapport au fond de la cuve 100, pour obtenir, selon le principe des vases communicants, un niveau de liquide correspondant dans le circuit de chauffage situé dans la double cloison 200.By examining Figures 1 and 2 in more detail, it is noted that it suffices to fill the
Sous réserve que le niveau ait été établi pour avoir (H - D < hm), nous obtenons, dès que la soufflante 210 est mise en fonction, une chasse du liquide contenu dans le circuit de chauffage, de la volute de refoulement 211 vers la chambre de chauffage 230, accompagnée d'un effet de trombe, dès que de l'air arrive à passer le long de la paroi supérieure 221 Pour déboucher sous la chambre de chauffage 230, en projetant, à l'intérieur de celle-ci et vers l'entrée du carter 240, des paquets de liquide, qui viennent, par effet de choc, décoller et fractionner les dépôts de bourre antérieurs. Le syphon étant alors désamorcé, le déplacement du liquide s'inverse pour pénétrer, avec une certaine inertie, dans la volute de refoulement 211, d'où il est à nouveau chassé selon le même processus pour, finalement, générer un phénomène cyclique se traduisant par des actions répétées sur les dépôts de bourre les plus tenaces, entraînant leur élimination complète, sous réserve que la soufflante 210 soit maintenue en fonction pendant un temps suffisant.Provided that the level has been established to have (H - D <hm), we obtain, as soon as the
A noter que cette opération peut être effectuée, en temps masqué, pendant l'essorage, sous réserve que de l'eau du dernier bain de rinçage ait été retenue prisonnière dans le circuit de chauffage, par l'intermédiaire d'une vanne pilotée, dès que le niveau d'eau dans la cuve est descendu sous le niveau optimal (H), tel que défini ci-dessus. La soufflante étant alors mise en fonction, l'opération d'élimination de la bourre peut être terminée au même moment que l'opération d'essorage, le liquide de débourrage étant alors évacué en même temps que l'eau résultant de l'essorage du linge.Note that this operation can be carried out, in masked time, during spinning, provided that water from the last rinsing bath has been held captive in the heating circuit, by means of a piloted valve, as soon as the water level in the tank has dropped below the optimal level (H), as defined above. The blower then being put into operation, the fluff removal operation can be completed at the same time as the spinning operation, the fluffing liquid then being discharged at the same time as the water resulting from the spinning. linen.
On comprend alors que le procédé et le dispositif selon l'invention ne se limitent pas à cet exemple d'application à une machine à chargement frontal, et qu'ils peuvent être utilisés sur d'autres machines à laver et à sécher le linge, notamment à chargement par le dessus, sous réserve que la soufflante et la chambre de chauffage soient réunies par une conduite pour constituer un U, dont elles occuperaient, respectivement, l'extrémité de chaque branche.It will then be understood that the method and the device according to the invention are not limited to this example of application to a loading machine front, and that they can be used on other washing and drying machines, especially top-loading, provided that the blower and the heating chamber are joined by a pipe to form a U, of which they would occupy, respectively, the end of each branch.
