Abstract

L'invention concerne un lave-linge (1), le lave-linge (1) comprenant : une unité de reconnaissance d'images (7), qui reconnaît des images d'un réservoir de lavage (1b) et de zones à proximité de ce dernier ; une unité de détection d'objet mobile (8), qui détecte le réservoir de lavage (1b) et des objets mobiles à proximité de ce dernier en fonction de plusieurs images possédant des temps de reconnaissance différents qui sont reconnues au moyen de l'unité de reconnaissance d'images (7) ; et une unité de commande (1g), qui modifie la commande de fonctionnement en fonction de la présence ou de l'absence d'un objet mobile détecté au moyen de l'unité de détection d'objet mobile (8) ou de la quantité de mouvement de l'objet mobile. Le lave-linge (1) permet une commande plus précise, un temps de fonctionnement plus court et une détection d'anomalie plus précise au moyen de la reconnaissance correcte de l'état du linge.
