Title
(EN) FRONT-LOADING WASHING MACHINE AND CONTROL METHOD THEREFOR
(FR) MACHINE À LAVER À CHARGEMENT FRONTAL ET PROCÉDÉ DE COMMANDE ASSOCIÉ
(ZH) 一种滚筒洗衣机及其控制方法
Abstract
(EN)
A front-loading washing machine and control method therefor. The front-loading washing machine comprises an inner drum (17). During washing clothes, the inner drum (17) contains washing water. The inner drum (17) is provided, along the circumferential direction of the inner wall thereof, with a plurality of annular water collection grooves (48, 49), and along the axial direction thereof, an axial water collection groove (50) penetrating through and communicating the annular water collection grooves (48, 49) with each other. A water drainage device (45) is provided in the annular water collection grooves (48, 49). Because the inner wall of the inner drum (17) of the front-loading washing machine has the annular water collection grooves (48, 49), N peak and trough structures are formed on the wall surface of the inner drum (17) to implement the gathering of centrifugally drained water in the annular water collection grooves (48, 49). Because the inner wall of the inner drum (17) has an axial groove structure, the axial water collection groove (50) implements communicating the annular water collection grooves (48, 49) with each other, such that water in the annular water collection grooves (48, 49) are more quickly and easily gathered and then drained by the water drainage device (45), thereby implementing efficient water drainage and water drainage during dewatering.

L'invention concerne une machine à laver à chargement frontal et un procédé de commande associé. La machine à laver à chargement frontal comprend un tambour interne (17). Pendant le lavage des vêtements, le tambour interne (17) contient de l'eau de lavage. Le tambour interne (17) est pourvu, sur la périphérie de sa paroi interne, d'une pluralité de rainures de collecte d'eau annulaires (48, 49), et dans son sens axial, d'une rainure de collecte d'eau axiale (50) pénétrant à travers et faisant communiquer les rainures de collecte d'eau annulaires (48, 49) les unes avec les autres. Un dispositif de drainage d'eau (45) est prévu dans les rainures de collecte d'eau annulaires (48, 49). Du fait que la paroi interne du tambour interne (17) de la machine à laver à chargement frontal comprend les rainures de collecte d'eau annulaires (48, 49), N structures de pic et de creux sont formées sur la surface de paroi du tambour interne (17) pour permettre la collecte d'eau drainée par centrifugation dans les rainures de collecte d'eau annulaires (48, 49). Du fait que la paroi interne du tambour interne (17) comprend une structure de rainure axiale, la rainure de collecte d'eau axiale (50) permet la communication des rainures de collecte d'eau annulaires (48, 49) les unes avec les autres, de telle sorte que l'eau dans les rainures de collecte d'eau annulaires (48, 49) est collectée plus rapidement et facilement et ensuite drainée par le dispositif de drainage d'eau (45), ce qui permet de mettre en œuvre un drainage d'eau efficace et un drainage d'eau pendant l'évacuation de l'eau.
