Title:
FRONT-LOADING WASHING MACHINE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/135314
Kind Code:
A1
Abstract:
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.
