Title:
WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/174502
Kind Code:
A1
Abstract:
A washing machine, comprising a box (1), a washing tub (2) rotatably disposed in the box (1). The washing tub (2) is configured as a barrel structure for containing water during washing; a water guiding passage (4) for guiding washing water from top to bottom for drainage is provided on the peripheral wall of the washing tub (2); the upper end of the water guiding passage (4) is a water inlet end and the water guiding passage (4) is provided with a water inlet (41) communicated with the interior of the washing tub (2); the upper part of the washing tub (2) is further provided with a water collecting and guiding structure (3) that guides the washing water rising due to a centrifugal force to the water inlet (41) and to enter the water guiding passage (4) so as to be drained out of the washing tub (2). The water collecting and guiding structure (3) comprises a water blocking unit (31) that prevents the washing water from continuing rising along the inner peripheral wall of the washing tub (2); the lower surface of the water blocking unit (31) facing the bottom of the washing tub (2) is a water blocking end surface (310) that prevents the water from climbing; the water blocking end surface (310) defines a water guiding path that guides the washing water to enter the water guiding passage (4) in a circumferential direction. The washing machine can quickly guide the washing water into the water guiding passage (4) by using the water collecting and guiding structure (3) disposed at the upper part of the washing tub (2), thereby increasing the drainage speed and improving the dewatering efficiency.
