Abstract:
(EN) Provided is a method for controlling a clothes treatment apparatus comprising: a tub for receiving water; a drum which is rotatably disposed in the tub and receives clothes; a chamber which is in communication with the tub and in which a pressure corresponding to a water level of the tub is formed; an elastic part disposed inside the chamber and elastically deformed according to a change in the pressure of the chamber; an output unit for generating an electrical signal corresponding to the amount of deformation of the elastic part, the output unit including a plurality of gauge resistors disposed on one surface of the elastic part; and a control unit for receiving the electrical signal and comparing the same with a reference electrical signal indicating the state where the tub has a water level of zero, so as to sense the level of water received in the tub. The method comprises: discharging water from the tub; detecting an electrical signal from the output unit; comparing the detected electrical signal with a reference electrical signal; and correcting the reference electrical signal when the difference between the reference electrical signal and the detected electrical signal is out of a predetermined first setting range.
(FR) L'invention concerne un procédé de commande d'un appareil de traitement de vêtements comprenant : une cuve pour recevoir de l'eau; un tambour qui est disposé en rotation dans la cuve et reçoit des vêtements; une chambre qui est en communication avec la cuve, et dans laquelle une pression correspondant à un niveau d'eau de la cuve est formée; une partie élastique disposée à l'intérieur de la chambre et déformée élastiquement selon un changement de pression de la chambre; une unité de sortie pour générer un signal électrique correspondant à l'amplitude de déformation de la partie élastique, l'unité de sortie comprenant une pluralité de résistances de jauge disposées sur une surface de la partie élastique; et une unité de commande pour recevoir le signal électrique et le comparer à un signal électrique de référence indiquant l'état dans lequel la cuve a un niveau d'eau de zéro, de façon à détecter le niveau d'eau reçue dans la cuve. Le procédé comprend les étapes suivantes : évacuer l'eau de la cuve; détecter un signal électrique provenant de l'unité de sortie; comparer le signal électrique détecté à un signal électrique de référence; et corriger le signal électrique de référence lorsque la différence entre le signal électrique de référence et le signal électrique détecté est hors d'une première plage de réglage prédéterminée.
