Title (EN) CONTROL DEVICE FOR WASHING MACHINE
(FR) DISPOSITIF DE COMMANDE POUR MACHINE A LAVER LE LINGE
Abstract:
(EN) A control device for the washing machine, which device judges the kinds and levels of dirtiness of laundry for maintaining clean conditions after washing and controls washing with high precision in real time with accelerated judgement. A light transmission sensing unit (19) for detecting the light transmission level of washing fluid is provided in the washing tub, and further provided is a microcomputer (16) which detects the light transmission level found by said transmission detecting unit (19) and a length of time required for the transmission level to reach a saturation, handles the light transmission level and length of time for saturation as information on the level and kind of dirtiness, and determines a length of time for washing according to a control table in which a length of time for washing has been determined from a light transmission level and a length of time for saturation.
(FR) Dispositif de commande pour machine à laver le linge. Il évalue la nature et le degré de saleté du linge pour maintenir la propreté après le lavage. Il commande en outre les opérations de lavage avec une extrême précision, en temps réel et avec une capacité d'évaluation accélérée. Un élément de détection de la transmission de lumière (19) du fluide de lavage est installé dans la cuve. Un micro-ordinateur (16) détecte le niveau de transmission de lumière relevé par ledit élément (19), ainsi que le laps de temps nécessaire pour que ce niveau atteigne le point de saturation. Il traite ensuite ces deux informations comme informations relatives au degré et à la nature de la saleté et calcule la durée du temps de lavage en fonction d'un tableau de commande dans lequel le temps de lavage a été calculé à partir des deux informations sus-mentionnées.
