Abstract
(EN)
Disclosed is a washing machine which can reduce uneven washing and fabric damage and which can improve washing performance. A pulsator comprises: a base portion; a movable blade portion, which protrudes from a configuration surface of the base portion; a movable mechanism portion capable of changing the protruding height of the movable blade portion according to the direction of rotation of the pulsator; a driving motor; and a control portion. The movable mechanism portion comprises: a rotary portion capable of rotating relative to the base portion; and a movable cam causing, following the rotation of the rotary portion, the movable blade portion to move towards a protruding position. The base portion comprises a first blocking rib, and when the movable blade portion moves to the protruding position, the rotary portion comes into contact with the first blocking rib. The control portion performs rotation start rising control on the driving motor, so that the rising interval until a target rotation speed is obtained comprises a first interval and a second interval subsequent to the first interval, and a uniform speed is set in the first interval, the rotary portion comes into contact with the first blocking rib in the first interval, and the rotary portion and the base portion rotate as a whole.

L'invention concerne une machine à laver qui peut réduire un lavage irrégulier et un endommagement de l'étoffe et qui peut améliorer les performances de lavage. Un pulsateur comprend : une portion de base; une portion d'aube mobile qui fait saillie à partir d'une surface de configuration de la portion de base; une portion de mécanisme mobile capable de modifier la hauteur saillante de la portion d'aube mobile en fonction de la direction de rotation du pulsateur; un moteur d'entraînement; et une portion de commande. La portion de mécanisme mobile comprend : une portion rotative capable de tourner par rapport à la portion de base; et une came mobile qui, suite à la rotation de la portion rotative, amène la portion d'aube mobile à se déplacer vers une position saillante. La portion de base comprend une première nervure de blocage, et lorsque la portion d'aube mobile se déplace vers la position saillante, la portion rotative entre en contact avec la première nervure de blocage. La portion de commande effectue une commande de montée de début de rotation sur le moteur d'entraînement, de sorte que l'intervalle de montée jusqu'à ce qu'une vitesse de rotation cible soit atteinte comprend un premier intervalle et un deuxième intervalle consécutif au premier intervalle, et une vitesse uniforme est réglée dans le premier intervalle. La portion rotative vient en contact avec la première nervure de blocage dans le premier intervalle et la portion rotative et la portion de base tournent d'un seul tenant.
