Kind Code:
A1
Abstract:
A drainage valve assembly (3) and a laundry treatment device. The drainage valve assembly (3) comprises a valve core (31), a transmission rod mechanism (32), and an elastic reset member. The transmission rod mechanism (32) has a rotation center line (L), and comprises a transmission rod (321) and a first shift rod (322) that are connected to each other. A first end of the transmission rod (321) directly or indirectly drives the valve core (31) to move. The first shift rod (322) is connected to a second end of the transmission rod (321). The elastic reset member is used for driving the transmission rod (321) to be reset to an initial position. Regarding the laundry treatment device, regardless of a rotational speed of an inner tub (11), as long as the transmission rod mechanism (32) can be rotated, the valve core (31) can be switched between a sealing position and a drainage position, and high drainage reliability is achieved.
