Description

La présente invention a pour objet une machine à laver le linge,The present invention relates to a washing machine laundry,

Une machine à laver comprend un chassis à l'intérieur duquel est montée une cuve contenant le tambour tournant.A washing machine includes a frame inside which is mounted a tank containing the rotating drum.

La cuve est suspendue à la partie supérieure du chassis à l'aide de ressorts hélicoïdaux, visant à amortir le déséquilibre se produisant lors de la rotation du tambour et du mouvement du linge à l'intérieur de celui-ci. Néanmoins, il est indispensable notamment en période d'essorage où le déséquilibre dû à une répartition irrégulière du linge est le plus important, d'améliorer l'amortissement par friction de patins solidaires de la partie inférieure de la cuve dans ses garnitures solidaires du chassis et par le montage d'éléments de lestage sur la cuve renforçant la stabilité de celle-ci.The tank is suspended from the upper part of the chassis using helical springs, designed to cushion the imbalance occurring when rotating the drum and the movement of the laundry inside it. However, it is essential especially during the spinning period when the imbalance due to irregular distribution of the laundry is most importantly, improve friction damping pads attached to the lower part of the tank in its fittings secured to the chassis and by mounting ballast elements on the tank enhancing the stability of this one.

D'autres solutions consistent à utiliser des systèmes de support et d'amortissement telles que décrites dans le Brevet Français 2.540.207 et le brevet Européen EP 326.502. Les éléments de lestage de 10 à 25 Kg suivant la capacité de charge, de la vitesse de rotation du tambour, de la qualité de la machine à laver, sont constitués généralement par des pièces en fonte ou en béton fixées sur la face extérieure de la cuve.Other solutions consist in using support and damping as described in the French patent 2,540,207 and European patent EP 326,502. Ballast elements from 10 to 25 kg depending on the capacity of load, drum rotation speed, quality of washing machine, generally consist of parts cast iron or concrete fixed to the outside of the tank.

Il en résulte la nécessité de manipuler ces éléments de lestage à de nombreuses reprises, lors de l'approvisionnement en usine, de leur stockage et de leur montage sur les machines. En outre, ils augmentent de façon sensible le poids des machines finies, ce qui rend plus difficile la manipulation de celles ci lors des livraisons, dépannages ou déménagements. Enfin, compte tenu du volume de ces éléments, il n'est pas toujours possible de les monter aux emplacements les mieux adaptés. This results in the need to manipulate these elements of ballasting many times during factory supply, their storage and their mounting on machines. In addition, they increase so sensitive the weight of finished machines, which makes it more difficult handling of these during deliveries, repairs or moves. Finally, given the volume of these elements, it is not always possible to mount them in the most suitable locations.

Selon le brevet EP 326502, la machine à laver a au moins un réservoir de lestage alimenté directement en eau du réseau. La cuve du lave-linge peut être alimentée ou directement du réseau ou bien du réservoir de lestage, le programmateur agissant sur un robinet connecté à l'amont à l'eau du réseau.According to patent EP 326502, the washing machine has at least one reservoir for ballast supplied directly with mains water. The washing machine tank can be supplied either directly from the network or from the ballast tank, the programmer acting on a tap connected upstream to the mains water.

Le brevet DE 1902325 décrit une machine à laver ayant un réservoir de lestage qui peut être connecté à l'amont à l'eau du réseau et à l'aval à la cuve.Patent DE 1902325 describes a washing machine having a reservoir for ballast which can be connected upstream to the mains water and downstream to the tank.

Le but de l'invention est de conserver les avantages du Brevet européen EP 326502 en en créant de nouveaux.The object of the invention is to retain the advantages of the European patent EP 326502 by creating new ones.

Dans cette nouvelle invention, le lestage à eau possède une valeur variable adaptée aux conditions d'utilisation, dans laquelle le lavage des tissus s'effectue dans de bien meilleures conditions économiques sur l'énergie et l'eau.In this new invention, the water ballast has a variable value adapted to the conditions of use, in which the washing of fabrics is carried out in good better economic conditions on energy and water.

Ceci, avec une programmation spécifique, conditionne une gestion technique des volumes d'eau avec des éléments de répartition pendant son fonctionnement, sur un ensemble tenant compte des volumes d'encombrement et ses formes d'exécutions nécessaires aux mouvements d'amplitudes spécifiques aux types de chassis qui la contiennent.This, with specific programming, conditions a technical management of water volumes with elements of distribution during operation, over a set taking into account the overall dimensions and its forms of executions necessary for amplitude movements specific to the types of chassis that contain it.

Les machines à laver le linge industrielles, destinées aux collectivités, présentent tous ces inconvénients amplifiés par des masses d'autant plus volumineuses et plus lourdes.Industrial washing machines, intended for communities, have all these amplified disadvantages by masses all the more voluminous and heavier.

Compte tenu des difficultés d'encombrement des machines équipées de lests en fonte ou en béton, il n'est pas possible de loger dans un chassis intérieur de machine, un réservoir destiné à récupérer les eaux de rinçage suffisamment claires pour leur réutilisation en eau de lavage additionnée de produits de lessive qui sera, elle, rejetée en eau usée en fin de lavage pour exemple.Taking into account the difficulties of the dimensions of the machines fitted with cast iron or concrete weights, it is not possible to fit in an interior machine frame, a tank for collecting rinsing water clear enough for reuse in washing with detergent which will be discharged into waste water at the end of washing for example.

La solution idéale pour le support de cette technologie innovante est contenue dans le brevet EP 326.502 qui permet, avec la présente invention une réalisation touchant le domaine de la maítrise de l'énergie et de l'environnement.The ideal solution for supporting this technology innovative is contained in patent EP 326,502 which allows, with the present invention an embodiment affecting the field of energy and environmental management.

Il ne résulte pas de limitation quelconque à l'application de la présente invention, la machine à laver représente le type idéal d'appareil, qualifié, de gros consommateur d'eau et d'énergie.It does not result from any limitation to the application of the present invention, the washing machine represents the ideal type of device, qualified, heavy consumer of water and energy.

Les réserves naturelles d'eau et d'énergie n'étant pas inépuisables, la présente invention permet une gestion plus prudente de l'environnement, anti gaspillage, dont les retombées ne sont pas négligeables. De plus, tout ceci constitue des améliorations de conditions de travail, économies de matière, économies d'énergie, économie d'eau tant sur le domaine industriel que sur le plan de l'utilisateur.The natural reserves of water and energy not being inexhaustible, the present invention allows more management environmentally friendly, anti waste, the consequences of which are not negligible. In addition, all of these constitute improvements in working conditions, material savings, savings energy, water saving both in the industrial and in terms of the user.

Sur d'autres plans, comme par exemple les Agences de Bassins où le domaine des eaux doit se traiter en volumes de pompage de la nappe phréatique ainsi que des volumes de traitements des eaux usées, on trouve là matière à économies et améliorations.On other plans, such as the Basin Agencies where the water domain must be treated in pumping volumes groundwater and treatment volumes wastewater, there is room for savings and improvements.

L'invention contient un procédé de fonctionnement et des composants spécifiques à des fins de fiabilité et d'économies dont les opérations sont synchronisées par un programmateur .The invention contains an operating method and specific components for reliability and savings whose operations are synchronized by a programmer.

A cet effet, le type de machine qu'elle concerne comprend une cuve qui, montée à l'intérieur d'un chassis avec interposition d'éléments amortisseurs est équipée d'éléments de lestage avec circulation d'eau, tel que défini dans le brevet EP 326.502. Selon l'invention, le ou les réservoirs de lestage comportent une sécurité électrique de remplissage intégral, tel un pressostat ou flotteur, liée aux divers fonctionnements de remplissage avec alimentation en eau du réseau. L'alimentation s'effectue en toute sécurité lors des opérations d'essorage. Les réservoirs pleins font office de lestage maximum. Une programmation est spécifique à ces opérations ainsi que le fonctionnement d'électro-vannes spécifiques pour alimenter la cuve par gravité à partir de ce ou ces réservoirs pour les différents besoins en eau de lavage, rinçage pour vidanger cette cuve avec une pompe spécifique pouvant aussi vidanger le ou les lests lorsqu'on la souhaite pour rejeter les eaux usées, pour stocker des eaux sélectionnées, telle que la dernière eau de rinçage dans son volume initial, c'est à dire dans le ou les lests laissés vides ou partiellement vides à cet effet par la programmation, pour réutiliser cette dernière eau sur le cycle suivant, en lavage additionnée de produits de lessive à cet effet, pour enfin rejeter celle-ci en eau usée.For this purpose, the type of machine it concerns includes a tank which, mounted inside a chassis with interposition of damping elements is equipped with elements ballasting with water circulation, as defined in the Patent EP 326,502. According to the invention, the or the ballast tanks have a safety electric full filling, such as a pressure switch or float, linked to the various filling operations with mains water supply. The feeding takes place in all safety during spin operations. Full tanks act as maximum ballast. A programming is specific to these operations as well as the operation specific solenoid valves to feed the tank by gravity from this or these tanks for the different needs in washing water, rinsing to empty this tank with a specific pump that can also drain the ballast (s) when desired to discharge wastewater, to store selected waters, such as the last water in rinsing in its initial volume, i.e. in the ballasts left empty or partially empty for this purpose by the programming, to reuse this last water on the next cycle, washing with detergent added for this purpose, to finally reject it in waste water.

La cuve est alimentée par gravité à l'aide d'électro-vannes placées sur le ou les réservoirs de lestage de manière à faire écouler des volumes d'eau tarés et souhaités pour les différents besoins du cycle de la machine. L'invention concerne également les électro-vannes qui sont élaborées de manière à pouvoir traiter de l'encombrement sur l'ensemble suspendu lest-cuve surtout au moment de l'essorage où les mouvements d'amplitude de l'ensemble sont importants, ce qui limite les risques de chocs ou d'accrochage par les parties en relief.The tank is fed by gravity using of solenoid valves placed on the ballast tank (s) so as to drain tared volumes of water and desired for the different needs of the cycle of machine. The invention also relates to the solenoid valves which are designed to deal with the size of the ballast-tank suspension assembly, especially at moment of spin when the amplitude movements of all are important, which limits the risks of impact or snagging by raised parts.

La machine à laver connue du Brevet EP 326.502 ( Fig.1) est équipée de réservoirs de lestage 5, chaque réservoir alimente la cuve 9 depuis sa partie supérieure, par poussée de l'eau du réseau, directement ou indirectement à travers une boite à produits 7. La cuve 9 et le réservoir 5 sont cloisonnés par un couvercle 16 en vue éclatée ( fig.1bis).The washing machine known from Patent EP 326.502 (Fig. 1) is equipped with ballast tanks 5, each tank feeds the tank 9 from its upper part, by pushing water from the network, directly or indirectly through a product box 7. The tank 9 and the tank 5 are partitioned by a cover 16 in exploded view (fig. 1bis).

Avantageusement, la présente invention est caractérisée en ce que le ou les réservoirs de lestage 5 sont équipés d'une sécurité 18 ( fig.2) commandant l'amenée d'eau dans le réservoir 5 à partir du robinet réseau 1, d'un tuyau souple 2, d'une électro-vanne 3, et d'un tuyau 4, branché sur le réservoir 5, qui par la sécurité 18 assure du remplissage intégral.Advantageously, the present invention is characterized in that the ballast tank (s) 5 are equipped with a safety 18 (fig. 2) controlling the supply of water to the tank 5 from network tap 1, flexible hose 2, a solenoid valve 3, and a pipe 4, connected to the tank 5, which by safety 18 ensures filling integral.

Cette solution est très intéressante car elle permet à l'aide d'électro-vanne 25 et 28 ( fig. 2bis ) et ( fig.11 à 15 ) d'alimenter la cuve 9 par gravité, soit pour le besoin en eau de lavage par l'électrovanne 25, soit pour l'eau de rinçage par l'électrovanne 28 avec interposition d'un tuyau 31.This solution is very interesting because it allows using solenoid valve 25 and 28 (fig. 2bis) and (fig.11 to 15) to feed the tank 9 by gravity, either for the need in washing water by solenoid valve 25, or for rinsing water by solenoid valve 28 with interposition of a pipe 31.

Bien avantageusement, ces électro-vannes ne subissent aucune contrainte de pression du réseau et d'autre part, comparativement à la (fig.10), qui est une électro-vanne double courante, la forme et l'orientation de -tous les branchements tuyau 31 et cosses 47 permettent un encastrement dans des cavités comme sur le réservoir 5 (fig. 12 ) à titre d'exemple.Advantageously, these solenoid valves do not undergo any network pressure constraint and secondly, compared to (fig.10), which is a solenoid valve double current, the shape and orientation of all hose 31 and lug 47 connections allow installation in cavities as on tank 5 (fig. 12) as an example.

L'électro-vanne 25 (fig.11) est une forme d'exécution réalisant un seul point d'écoulement sur le réservoir 5 dont l'étanchéité est assurée à l'aide d'un joint 48 et sa fixation par encliquetage sur le réservoir assure son maintien par deux branches élastiques à l'extrémité (fig.12). Une autre forme d'exécution ( Fig.13 ) permet de collecter par le tuyau 31, l'eau de l'électro-vanne 25 ( Fig. 11) et de l'acheminer vers la cuve 9 par le tuyau 31 bis. Une dernière forme d'exécution sans limitation de quantité d'électro-vannes réside, dans le principe de collecter différents volumes 24 et 32 à différentes hauteurs 26 et 29 du réservoir 5 avec des durits ou tuyaux rassemblés au point de fixation des électro-vannes tel qu'illustrées Fig. 15 Fig. 14. Toutes ces formes d'exécution sont d'autant plus avantageuses que les parties en relief sur le réservoir 5, moins importantes que celles de type courant ( Fig. 10 ), diminueront les risques d'accrochage ou de chocs avec les composants ou le chassis de la machine, en période d'essorage où les mouvements d'amplitude de l'ensemble lest et cuve suspendu sont importants.The solenoid valve 25 (fig. 11) is an embodiment providing a single pour point on the reservoir 5 of which sealing is ensured using a seal 48 and its snap-fastening on the tank ensures held by two elastic arms at the end (fig. 12). Another form of execution (Fig. 13) allows to collect through the pipe 31, the water from the solenoid valve 25 (Fig. 11) and to route it to the tank 9 via the pipe 31 bis. A last form of execution without quantity limitation of solenoid valves resides in the principle of collecting different volumes 24 and 32 at different heights 26 and 29 from tank 5 with hoses or pipes assembled at the point of fixing the solenoid valves as illustrated in Fig. 15 Fig. 14. All these forms of execution are all the more advantageous than the raised portions on the reservoir 5, less important than those of the common type (Fig. 10), will reduce the risk of snagging or impact with components or the machine chassis, in period spin where the amplitude movements of the ballast assembly and suspended tank are important.

Compte tenu de l'alimentation de la cuve 9 par gravité à partir du lest 5, et en particulier à l'ouverture de l'électro-vanne 28 qui commande l'écoulement du volume rinçage du lest 5 à la cuve 9 et plus particulièrement au dernier rinçage 540 au pas 531 ( Fig. 3), l'eau, après le bain de rinçage dans la cuve 9, est vidangée mais stockée dans son contenant initial, le réservoir 5 ( volume 542 fig. 3 ) laissé vide à cet effet. Cela a pour conséquence avantageuse, de recycler une eau claire provenant du tout dernier rinçage pour des besoins en lavage, rinçage des cycles suivants de la machine, surtout un lavage additionné de produits lessiviels.Given the supply to the tank 9 by gravity at from ballast 5, and in particular at the opening of the solenoid valve 28 which controls the flow of the volume rinsing the ballast 5 in the tank 9 and more particularly in the last rinse 540 in step 531 (Fig. 3), water, after rinsing bath in tank 9, is drained but stored in its initial container, the reservoir 5 (volume 542 fig. 3) left blank for this purpose. This has as consequences advantageous, to recycle clear water from the very last rinse for washing, rinsing needs subsequent machine cycles, especially an added wash detergents.

A cet effet spécifique de la fonction pompe 13 ( Fig. 7 ) de type courant, amélioré pour la présente invention ( Fig. 8 ), un système bi passage 41 actionné par une bobine électro-magnétique 42, permet à l'arrêt de celle-ci de rejeter les eaux usées de la cuve 9 par la pompe 13 et le tuyau de vidange 15, et, ou, de canaliser l'eau de rinçage à restocker pour recyclage ( avec la fonction de 42 ) dans le lest 5 par le tuyau 21 ( Fig. 2 et 2 bis ). Une réalisation de cette pompe plus compacte est illustrée (Fig. 9 ). Cette pompe permet de vidanger la cuve 9 par l'intermédiaire de la durit 11 dont le récepteur est 12, 41 est le bi-passage actionné par la bobine 42 qui aiguille l'eau soit sur 15 qui est le tuyau de vidange des eaux usées en rejet, soit sur 21 qui est le tuyau canalisant les eaux à recycler dans le réservoir 5 avec un filtre 19 .For this specific purpose of the pump function 13 (Fig. 7) of common type, improved for the present invention (FIG. 8), a dual passage system 41 actuated by a coil electro-magnetic 42, allows it to stop discharge the waste water from tank 9 by pump 13 and the drain hose 15, and, or, channel the rinse water to restock for recycling (with the function of 42) in the ballast 5 by pipe 21 (Fig. 2 and 2a). A realization of this more compact pump is illustrated (Fig. 9). This pump allows to drain the tank 9 via the hose 11 whose receiver is 12, 41 is the bi-passage activated by the coil 42 which directs the water to be on 15 which is the pipe for draining wastewater in discharge, that is to say 21 which is the pipe channeling the water to be recycled in the tank 5 with a filter 19.

Une tubulure en saillie 46, réceptionne l'eau du ou des lests 5 et de la cuve 9 si on désire alléger la machine. Manutentions, déplacements, déménagements, etc... Afin de vidanger en position 500 du programmateur ( à l'arrêt ) une touche 107 ( Fig. 4 ) est prévue pour cette opération ouvrant la vanne électrique 44 mettant en communication le ou les réservoirs 5 et la cuve 9 avec la pompe 13, ceci avec la touche MARCHE de la machine 201 ( Fig. 4 ) porte fermée 101.A protruding tube 46, receives the water from the ballasts 5 and of tank 9 if it is desired to lighten the machine. Handling, moving, moving, etc. In order to drain in position 500 of the programmer (when stopped) key 107 (Fig. 4) is provided for this operation opening the electric valve 44 connecting the or the tanks 5 and the tank 9 with the pump 13, this with the START key of the machine 201 (Fig. 4) with the door closed 101.

Les remplissages se refont automatiquement dès la remise en service de la machine de cette présente invention.The refills are refilled automatically upon resumption machine service of this present invention.

Pour que l'invention soit bien comprise, un diagramme de son programmateur ( Fig.3 ), un schéma de principe ( Fig. 4 ), des figures schématiques de fonctionnement de 18 à 37 ainsi que des portions du schéma électrique 4 ( Fig. 18 à 37 bis ou ter ) suivent pour sa description, des détails plus précis à son fonctionnement électrique programmé dans son principe.In order for the invention to be properly understood, a diagram of its programmer (Fig. 3), a block diagram (Fig. 4), schematic operating figures from 18 to 37 as well only portions of wiring diagram 4 (Fig. 18 to 37 bis or ter) follow for its description, more details precise to its electrical operation programmed in its principle.

D'une manière plus élaborée, le réservoir de lestage 5 ( Fig. 16 ) est compartimenté. L'eau arrive par son point de branchement 50 sur le lest 5 compartiment 51. Un clapet anti-retour 49 taré à une pression inférieure au réseau permet de faire passer l'eau du réseau dans le compartiment 52. Cependant l'eau restockée destinée au recyclage arrivant par 21 dans le compartiment 52, ne pourra pas atteindre le compartiment 51 qui comprendra toujours l'eau du réseau en direct. La Figure 17 traite des volumes d'eau dans la cuve 9, N.L. étant niveau lavage et met en évidence l'eau restante dans le lest 5 et la partie haute vide du lest 5. En médaillon sont représentées les électro-vannes des ( Fig. 12 et 13 ) relatifs à ces opérations d'alimentation cuve 9.In a more elaborate manner, the ballast tank 5 (Fig. 16) is compartmentalized. Water arrives by its point of connection 50 on the ballast 5 compartment 51. A valve check valve 49 calibrated at a pressure lower than the network allows the mains water to pass through the compartment 52. However, the restocked water intended for recycling arriving by 21 in compartment 52, cannot reach the compartment 51 which will always include mains water in direct. Figure 17 deals with the volumes of water in the tank 9, N.L. being washing level and highlights the water remaining in ballast 5 and the empty upper part of ballast 5. In the medallion are represented the solenoid valves of (Fig. 12 and 13) relating to these tank supply operations 9.

Le diagramme ( fig.3 ) du programmateur nécessaire à la présente invention constitue le cycle complet des opérations effectuées dans l'ordre chronologique entre les deux positions 500 qui constituent le point zéro ou arrêt du programmateur, à savoir l'arrêt de l'entrainement de son bloc cames par le moteur programmateur 150 alimenté en courant électrique 100 et 200 de la fig.4.The diagram (fig. 3) of the programmer necessary for the present invention constitutes the complete cycle of operations performed in chronological order between the two positions 500 which constitute the zero point or stop of the scheduler, i.e. stopping sound training cam block by the programmer motor 150 supplied with electric current 100 and 200 of fig. 4.

La sécurité de porte est référencée par 101 la touche marche-arrêt est référencée par 201. Le diagramme de la fig.3 est divisée en trois zones principales : 537 est la zone lavage qui compose le début de cycle à savoir, le brassage du linge dans de l'eau en général chauffée avec addition de produits lessiviels. La deuxième zone 538 constitue le premier rinçage, 539 le deuxième, 540 étant le dernier rinçage avec récupération de l'eau suffisamment claire à des fins de réutilisation pour le cycle suivant. Ces trois zones sont composées de pas ou avances du programmateur numérotées de 501 à 536.The door security is referenced by 101 the on-off key is referenced by 201. The diagram in fig. 3 is divided into three areas main: 537 is the washing area that makes up the start of cycle namely, the brewing of laundry in water while generally heated with addition of detergents. The second zone 538 constitutes the first rinse, 539 the second, 540 being the last rinse with recovery of water clear enough for reuse to the next cycle. These three zones are composed of steps or programmer advances numbered 501-536.

541 est le volume contenu dans la partie haute du lest 5 entre son point d'écoulement qui est l'électro-vanne 25, et la sécurité lest 18.541 is the volume contained in the upper part of the ballast 5 between its pour point which is the solenoid valve 25, and security ballast 18.

542 est le volume contenu dans la partie haute du lest 5 entre son point d'écoulement qui est l'électro-vanne 28, et la sécurité lest 18.542 is the volume contained in the upper part of the ballast 5 between its pour point which is the solenoid valve 28, and security ballast 18.

En exemple, le volume 542 se remplit ou est plein en 501 (case noircie )For example, volume 542 fills or is full in 501 (blackened box)

En 502 au volume 542, il manque la proportion de 541 pour être complet ( case blanche ). Le fait est que nous avons fourni à la cuve 9 le volume d'eau 546 qui s'est évacuée à l'ouverture de l'électro-vanne 25 et par la durit 31 pour se transformer dans la cuve 9 en volume 546 au niveau 23 de celle-ci.In 502 at volume 542, the proportion of 541 is missing for be complete (white box). The point is that we have supplied to tank 9 the volume of water 546 which was discharged at the opening of the solenoid valve 25 and through the hose 31 to transform in tank 9 into volume 546 at level 23 of this one.

Dans la colonne flêchée 545, sont numérotés les composants nécessaires au déroulement des opérations de cette machine à laver :

  • 150 est le micro-moteur du programmateur
  • 3 est l'électro-vanne d'alimentation en eau de réseau du lest ou réservoir 5 conditionné par la sécurité 18.

  • 28 est l'électro-vanne d'alimentation en eau de la cuve 9 par gravité depuis le lest ou réservoir 5 vers la cuve 9, déversant le volume 542 du lest 5 pour former le volume 547 dans la cuve 9 au niveau 27.
  • 22 est le chauffage conditionné par le thermostat 206 (fig.4) et le pressostat 242, lui-même conditionné par la cuve 9 vide ( point bas 204-241 et cuve 9 pleine niveau 23 (point haut 204-240 ).
  • 154 est le moteur d'entrainement du tambour 10 en petite vitesse lavage avec inverseur 156 et ou en grande vitesse pour l'essorage ( Fig.4 )
  • 13, est la pompe de vidange de la cuve 9 qui fonctionnent en même temps que 42, bobine électro-magnétique du bi-passage 41 permet le stockage de la dernière eau de rinçage ( claire ) en retour par le tuyau 21, dans son volume initial dans le lest 5, conditionné à cet effet.
    • In the arrowed column 545, the components necessary for the operation of this washing machine are numbered:
  • 150 is the programmer's micro-motor
  • 3 is the solenoid valve for supplying the ballast mains water or reservoir 5 conditioned by security 18.
  • 25 is the solenoid valve for supplying water by gravity from the ballast or tank 5 to the tank 9, discharging the volume 541 from the ballast 5 to form the volume 546 at level 23 of the tank 9.
  • 28 is the solenoid valve for supplying water to the tank 9 by gravity from the ballast or tank 5 towards the tank 9, discharging the volume 542 of the ballast 5 to form the volume 547 in the tank 9 at level 27.
  • 22 is the heating conditioned by the thermostat 206 (fig. 4) and the pressure switch 242, itself conditioned by the empty tank 9 (low point 204-241 and full level tank 9 23 (high point 204-240).
  • 154 is the drum drive motor 10 in low washing speed with inverter 156 and or in high speed for spinning (Fig. 4)
  • 13, is the emptying pump of the tank 9 which operate at the same time as 42, electromagnetic coil of the bi-passage 41 allows the storage of the last rinse water (clear) in return by the pipe 21, in its volume initial in ballast 5, conditioned for this purpose.

    • La colonne 543 flêchée mentionne les contacts d'alimentation actionnés par le bloc cames du programmateur afin d'alimenter les organes électriques de la colonne 545 flêchée en regard, par l'intermédiaire des contacts de la colonne 544 flêchée aux moments des cases noircies du diagramme.The arrowed column 543 mentions the power contacts actuated by the cam block of the programmer so to supply the electrical components of column 545 arrowed opposite, through the contacts of the column 544 arrowed at the times of the blackened boxes of the diagram.

    Le schéma de principe électrique ( Fig. 4 ) comporte 2 éléments qui n'apparaissent pas sur la ( Fig. 3 ). La sécurité lest 18 qui conditionne l'arrivée d'eau du réseau 3 ( lest vide ) conditionne l'essorage par l'intermédiaire du pressostat 242 ( cuve 9 vide ) le pressostat conditionne le chauffage ( cuve 9 au niveau 23 ). Les 2 organes ( 18 et 242) doivent leurs fonctions à l'état des contenants vides ou pleins suivant les opérations du diagramme ( Fig. 3 ) à effectuer.The electrical block diagram (Fig. 4) has 2 elements that do not appear in (Fig. 3). The ballast security 18 which conditions the water supply to the network 3 (empty ballast) conditions the spin using the pressure switch 242 (tank 9 empty) the pressure switch conditions the heating (tank 9 at level 23). The 2 organs (18 and 242) owe their function to the state of empty containers or full according to the operations of the diagram (Fig. 3) to carry out.

    L'eau arrive à partir du robinet du réseau de distribution 1 ( Fig. 18 ), relié par un tuyau souple 2 à l'électro-vanne 3 en fonction ( Fig. 18 bis ) qui alimente le réservoir 5 par un tuyau 4 jusqu'au remplissage intégral grace à la sécurité 18 qui coupe l'alimentation de l'électro-vanne 3 une fois les réservoirs pleins ( Fig. 19 et 19 bis ).Water comes from the tap of the distribution network 1 (Fig. 18), connected by a flexible hose 2 to the solenoid valve 3 in function (Fig. 18 bis) which supplies the reservoir 5 by a hose 4 until full filling thanks to safety 18 which cuts the power to the solenoid valve 3 once full tanks (Fig. 19 and 19 bis).

    Au pas 502, à l'arrêt de l'électro-vanne 3, l'eau contenue dans le lest 5 alimente la cuve 9 ( Fig. 20 ) à l'ouverture de l'électro-vanne 25 et par gravité avec le collecteur 31 (Fig. 20 bis, pas 502 de la Fig. 3 ).In step 502, when the solenoid valve 3 stops, the water contained in the ballast 5 feeds the tank 9 (Fig. 20) at the opening of the solenoid valve 25 and by gravity with the manifold 31 (Fig. 20 bis, step 502 in Fig. 3).

    L'eau contenue dans la cuve 9 au niveau 23, volume 546, correspond au volume 541 du réservoir 5 et qui vient de s'écouler ( Fig. 21 ). Cette eau dans la cuve actionne par sa pression le pressotat 242 pour établir le chauffage 22 (Fig. 21 bis ) aux pas indiqués sur le diagramme ( Fig. 3 ) et ( Fig. 22 ).The water contained in the tank 9 at level 23, volume 546, corresponds to the volume 541 of the reservoir 5 and which comes from flow (Fig. 21). This water in the tank operates by its pressure pressotate 242 to establish heating 22 (Fig. 21 bis) at the steps indicated on the diagram (Fig. 3) and (Fig. 22).

    Le chauffage 22 établi et le moteur 154 en petite vitesse à inversions 156 ( Fig. 4 ) et 22 bis ) constituent le principal d'une phase de lavage jusqu'au pas 514 ( Fig. 3 ).The heater 22 established and the engine 154 at low speed at inversions 156 (Fig. 4) and 22 bis) constitute the main from a washing phase to step 514 (Fig. 3).

    Avantageusement, pendant toute la durée du chauffage, le complément d'eau de lest 5 ne sera pas effectué par l'électro-vanne 3 pour éviter une dépense inutile d'énergie. L'eau restante contenue dans le réservoir 5 aura capté la chaleur du bain de lavage par rayonnement et par le contact de la paroi mitoyenne lest 5 et cuve 9 ( Fig. 23 "). Auparavant les lests en fonte ou en béton réceptionnaient cette chaleur qui ne pouvait être restituée. Cela permet avec la compensation, du niveau d'eau du lest 5 avec l'électro-vanne 3 du réseau ( Fig. 24 ) d'obtenir une eau tempérée au pas 517 ( Fig. 3 ) de manière à refroidir par la paroi mitoyenne des lests 5 et de la cuve 9 l'eau usée de lavage dans la cuve, progressivement, avant son rejet ( Fig. 25 et 25 bis ) au pas 519.Advantageously, during the entire heating period, the additional ballast water 5 will not be carried out by the solenoid valve 3 to avoid an unnecessary expenditure of energy. The remaining water contained in the tank 5 will have captured the heat of the washing bath by radiation and by contact of the party wall ballast 5 and tank 9 (Fig. 23 "). Previously weights in cast iron or concrete received this heat which could not be restored. This allows with compensation, ballast water level 5 with the solenoid valve 3 of the network (Fig. 24) to obtain water tempered in step 517 (Fig. 3) so as to cool by the dividing wall of ballast 5 and of tank 9 waste water from washing in the tank, gradually, before disposal (Fig. 25 and 25 bis) at step 519.

    Au pas 520, l'essorage s'effectue en toute sécurité d'amortissement avec le lest 5 plein ( Fig. 26 ).At step 520, the spin is carried out safely damping with full ballast 5 (Fig. 26).

    L'ouverture de l'électro-vanne 28 au pas 521 libère l'eau contenue au dessus d'elle ( Fig. 27 ). Cette eau tiède, permet d'établir le premier bain de rinçage dans la cuve 9 niveau 27, volume 547 son origine étant 542 ( Fig. 28 ) et évite le choc thermique qui, dans bien des cas détériore les textiles. La vidange aux pas 524 et 525 s'effectue de la même manière qu'en fin de lavage aux pas 519 et 520 du diagramme ( Fig. 3 ), de même que pendant cette vidange de la cuve 9 par la pompe 13 des eaux usées, l'électro-vanne 3 compense le niveau lest 5 ( Fig. 29 ) au cours du pas 519 pour préparer le lestage 5 et le maintenir pendant l'essorage au pas 520 qui ne s'effectue qu'à travers le point bas du pressostat 242 ( cuve 9 vide ) et le point haut sécurité 18 lest plein ( fig. 30 ).The opening of the solenoid valve 28 at step 521 releases the water contained above it (Fig. 27). This warm water, allows to establish the first rinsing bath in the tank 9 level 27, volume 547 its origin being 542 (Fig. 28) and avoids thermal shock which in many cases deteriorates textiles. The emptying in steps 524 and 525 is carried out from the same way as at the end of washing in steps 519 and 520 of diagram (Fig. 3), as well as during this emptying of the tank 9 by the waste water pump 13, the solenoid valve 3 compensates for ballast level 5 (Fig. 29) in step 519 to prepare the ballast 5 and maintain it for spinning in step 520 which only takes place through the low point of pressure switch 242 (tank 9 empty) and high point safety 18 full ballast (fig. 30).

    Le rinçage 539, pas 526 à 530 s'effectue de la même manière que 538 du pas 521 à 525.Rinse 539, not 526 to 530 is carried out in the same way as 538 from step 521 to 525.

    Le dernier rinçage 540, au pas 531, l'eau du lest 5 alimente la cuve 9 ( Fig. 31 ) avec le volume d'eau 542 pour former le niveau 27 volume 547. dans le même temps. La bobine électro-magnétique 42 est alimentée pour prévoir le passage de la dernière eau de rinçage ( Fig. 32 ) la plus claire par le conduit 21 en préparation du stockage de cette eau, dans son volume initial 542 laissé vide à cet effet. La pompe 13 fonctionnant avec 42, permet de refouler cette eau par 21 dans le lest 5 ( Fig.33 ).The last rinse 540, at step 531, the ballast water 5 supplies the tank 9 (Fig. 31) with the volume of water 542 to form level 27 volume 547. at the same time. The coil electro-magnetic 42 is powered to predict the passage of the last clearest rinse water (Fig. 32) by the conduit 21 in preparation for the storage of this water, in its initial volume 542 left empty for this purpose. Pump 13 operating with 42, allows this water to be pumped back by 21 in ballast 5 (Fig. 33).

    Le tuyau de vidange 15 est obstrué dans le bi-passage 41 pendant cette opération de rinçage final du pas 531 à 535.The drain pipe 15 is obstructed in the dual passage 41 during this final rinsing operation from step 531 to 535.

    Toutefois, si des manipulations manuelles intempestives du programmateur sont intervenues au cours de ce dernier rinçage amenant un surplus d'eau à stocker, par rapport au déroulement normal des opérations, la sécurité 18 met en coupure d'alimentation la bobine 42 qui transformera l'opération de stockage ( puisque lest 5 plein ) en opération de vidange ( Fig. 34 bis ) ceci aussi afin que le tambour 10 dans la cuve 9 n'entraine pas une eau résiduelle provoquant un mauvais essorage.However, if untimely manual manipulation of the programmer intervened during the latter rinsing bringing an excess of water to be stored, compared to the normal operations, security 18 power cut coil 42 which will transform the storage operation (since ballast 5 full) in emptying operation (Fig. 34 bis) this also so that the drum 10 in tank 9 does not cause residual water causing a bad spin.

    A l'inverse, dans le cas d'une intervention manuelle intempestive vidangeant en rejet une partie ou toute l'eau de la cuve 9 destinée au stockage, la sécurité 18 ( lestage incomplet ) au point bas, alimentera l'électro-vanne réseau ( Fig. 34 ter ) lest 5 plein, pour un essorage correct ( Fig. 34 ). Le lestage 5 reste plein à la fin du cycle ( Fig. 35 ) cette eau récupérée prendra la température du local, où la machine est branchée, ce qui comportera une économie notoire sur l'énergie du fait que l'eau de lavage du cycle suivant aura atteint une température non négligeable par rapport à l'eau du réseau. De plus, cette eau de lavage au pas 502 ( Fig. 36 ) est l'eau économisée recyclée avec addition de produits lessiviels, et sera rejetée en eau usée à la fin de zone lavage 537 pas 519 ( Fig. 3 ) par la pompe 13, ce qui donne une suite ininterrompue d'économies au fil des cyles de la machine avec la présente invention.Conversely, in the case of untimely manual intervention draining part or all of the water in the tank 9 intended for storage, safety 18 (incomplete ballasting) at the low point, will supply the network solenoid valve (Fig. 34 ter) ballast 5 full, for correct spinning (Fig. 34). Ballast 5 remains full at the end of the cycle (Fig. 35) this recovered water will take the temperature of the room, where the machine is connected, which will involve a noticeable saving on the energy that the next cycle wash water will have reaches a non-negligible temperature compared to water of the network. In addition, this wash water at step 502 (Fig. 36) is the saved water recycled with the addition of detergents, and will be discharged into waste water at the end of wash zone 537 not 519 (Fig. 3) by pump 13, which gives an uninterrupted series of savings over the years of the machine with the present invention.

    Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante, en fournissant une machine à laver de conception simple dont les éléments de lestage intégrés sont gérés par une programmateur pour leur contenance variable en eau, à des fins d'économie d'énergie et d'eau. Les réservoirs de lestage peuvent être vidangés en commande électrique manuelle, machine à l'arrêt, programmateur à zéro 500 ( Fig. 3,37,37 bis )avant toute manipulation de la machine.As is apparent from the above, the invention provides a great improvement to the existing technique, providing a washing machine of simple design whose elements integrated ballast are managed by a programmer for their variable water capacity, for saving purposes of energy and water. Ballast tanks can be drained by manual electric control, machine stopped, programmer at zero 500 (Fig. 3,37,37 bis) before any handling of the machine.
