Document Type and Number:
WIPO Patent Application WO/2023/173978
Kind Code:
A1
Abstract:
A washing machine and a control method therefor. The washing machine comprises: a water containing tub (100); a circulating filter pipeline, a water inlet end and a water outlet end of the circulating filter pipeline being separately communicated with the water containing tub (100); a filter device (600), provided on the circulating filter pipeline and having a water inlet (6101), a filtered water outlet (6102) and a waste discharge port (6103); and a waste discharge pipeline (240), communicated with the waste discharge port (6103) of the filter device (600). The washing machine further comprises a control valve assembly (900), comprising: a first valve body (910), provided between the water containing tub (100) and the water inlet (6101) of the filter device (600), and internally provided with a first valve plug (911) for controlling the connection/disconnection between the water containing tub (100) and the water inlet (6101); a second valve body (920), provided on the waste discharge pipeline (240), and internally provided with a second valve plug (921) for controlling the connection/disconnection of the waste discharge pipeline (240); and a driving member, in alternating transmission connection to the first valve plug (911) and the second valve plug (921), so as to drive one of the first valve plug (911) and the second valve plug (921) to move. In the control valve assembly, one driving member can alternatingly drive one of the first valve plug (911) and the second valve plug (921) to move, thus achieving separate control of the connection/disconnection of two independent water paths, the structure is simple, and the costs are reduced.
