Abstract
(EN)
In any type of washing machine, an amount of laundry introduced into the washing machine may be measured in a short time with high accuracy. A washing machine includes a rotational spin tub into which laundry is introduced; a driving unit including a motor for rotating the spin tub; and at least one processor configured to control the driving unit to rotate the spin tub at first rotational speed, control the driving unit to rotate the spin tub at second rotational speed, and indentify weight of the laundry based on acceleration at the time of changing of rotational speed of the spin tub from the first rotational speed to the second rotational speed and the second rotational speed.

Dans tout type de lave-linge, une quantité de linge introduite dans le lave-linge peut être mesurée en un court laps de temps avec une grande précision. Un lave-linge comprend une cuve rotative dans laquelle le linge est introduit; une unité d'entraînement comprenant un moteur pour faire tourner la cuve rotative; et au moins un processeur conçu pour commander l'unité d'entraînement afin d'entraîner en rotation la cuve rotative à une première vitesse de rotation, commander l'unité d'entraînement afin d'entraîner en rotation la cuve rotative à une seconde vitesse de rotation, et identifier le poids du linge sur la base d'une accélération au moment du changement de vitesse de rotation de la cuve rotative, de la première vitesse de rotation à la seconde vitesse de rotation, et sur la base de la seconde vitesse de rotation.
