Definitions

  • said electronic comparator means 5 is connected through its output 8 with the microcontroller means 1, whereas two different levels of signal can occur at said output 8 of the comparator means 5, such as for instance a zero level and a pre-set level in accordance with the comparison of the time applied to the input 6 with the time applied to the input 7 of said comparator means.
  • said microcontroller means causes said drain pump 3 to be switched off after a pre-determined period of time, which is considered to be adequate to allow the largest possible amount of the water contained in the tub to be pumped outside.
  • the signal occurring at the output 8 of said comparator means emphasizes another pre-determined level causing the microcontroller means 1 to generate the electrical signal 12 that is arranged to keep the drain pump 3 in its de-energized condition, ie.
  • said electronic counter means 4 and said electronic comparator means 5 can be directly included in the structure of said microcontroller means 1.
  • the control arrangement for the spin-extraction phase of the washing process of a clothes washing machine does in this way enable the duration of the final spin-extraction phase to be each time adapted automatically to both the actual characteristics of the different types of clothes and the actual amount of clothes in the washload, and therefore to the actual water adsorbing capacity of the same washload, while ensuring effective water extraction from the clothes and optimizing the way in which the whole washing process is ultimately performed.

Claims (4)

  1. Dispositif de commande pour la phase d'essorage dans les machines à laver le linge, en particulier les machines à laver le linge ou les machines combinées à laver et à sécher le linge, comprenant une cuve de lavage logeant un tambour rotatif de réception du linge, capable d'être entraîné en rotation par des moyens d'entraînement à moteur connus en soi, un moyen de microcontrôleur électronique pour régler et commander l'avancement de chaque cycle de lavage sélectionné par l'utilisateur, au moins un mano-contact ou moyen semblable de commande de niveau pour détecter un niveau de remplissage prédéterminé de lessive à l'intérieur de ladite cuve de lavage, et une pompe de vidange raccordée à ladite cuve pour évacuer la lessive extraite du linge et la recueillir dans ladite cuve pendant la phase finale d'essorage, caractérisé par des moyens de comptage (4) et des moyens de comparaison (5) raccordés de façon fonctionnelle avec ledit moyen de microcontrôleur électronique (1), avec ledit mano-contact (2) et ladite pompe de vidange (3), lesdits moyens de comptage (4) étant disposés pour compter le temps s'écoulant depuis le moment auquel ladite pompe de vidange (3) est désactivée par ledit moyen de microcontrôleur (1), jusqu'au moment auquel ledit niveau de remplissage prédéterminé de la lessive dans la cuve est atteint, commandé par ledit mano-contact (2), et lesdits moyens de comparaison (5) étant disposés pour comparer le temps compté par lesdits moyens de comptage (4) avec un temps de référence prédéterminé (Trif) correspondant à l'état dans lequel le linge dans le tambour ne contient plus une quantité appréciable d'eau résiduelle après un essorage approprié, et lesdits moyens de comparaison étant de plus disposés pour amener ladite pompe de vidange (3) à être soit mise à nouveau en fonctionnement ou à être maintenue dans son état désactivé, tout en coupant l'alimentation vers lesdits moyens d'entraînement à moteur et en amenant l'achèvement de la phase d'essorage, sous la commande dudit moyen de microcontrôleur électronique (1), lorsque ledit temps compté par lesdits moyens de comptage (4) est respectivement plus court que, ou est égal à ou plus long que ledit temps de référence prédéterminé (Trif).
  2. Dispositif de commande selon la revendication 1, caractérisé en ce que lesdits moyens de comptage comprennent un compteur électronique (4) raccordé auxdits moyens de comparaison (5) et audit mano-contact (2), ainsi qu'à la pompe de vidange (3), par l'intermédiaire dudit moyen de microcontrôleur (1), ledit compteur électronique (4) étant capable de recevoir dudit moyen de microcontrôleur (1) un signal de validation (10) et un signal de non-validation (9) pour respectivement commencer et arrêter ladite fonction de comptage du temps, lorsque ledit moyen de microcontrôleur (1) amene la mise hors tension de la pompe de vidange (3) et, respectivement, lorsque ledit mano-contact (2) détecte que la lessive dans la cuve a atteint le niveau de remplissage prédéterminé.
  3. Dispositif de commande selon la revendication 2, caractérisé en ce que lesdits moyens de comparaison comprennent un comparateur électronique (5) pourvu d'une première et d'une deuxième entrées (6, 7) qui sont respectivement raccordées audit compteur électronique à comptage de temps (4) et audit moyen de microcontrôleur (1) fournissant ladite information de temps de référence (Trif), et pourvu de même d'une sortie (8) raccordée audit moyen de microcontrôleur (1) et disposé pour fournir deux différents niveaux de signal, soit pour activer ladite pompe de vidange (3), soit pour la maintenir dans son état désactivé respectivement, selon le résultat de la comparaison du temps compté par ledit compteur électronique (4) avec ledit temps de référence prédéterminé (Trif), respectivement appliqué à ladite première et ladite deuxième entrée (6, 7).
  4. Dispositif de commande selon la revendication 3, caractérisé en ce que ledit compteur électronique (4) et ledit comparateur électronique (5) sont capables d'être intégrés dans ledit moyen de microcontrôleur (1).
