Title:
LAUNDRY TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/041387
Kind Code:
A1
Abstract:
Embodiments of the present application provide a laundry treatment device, comprising an inner drum, a driving apparatus, and a drain valve assembly. The inner drum can contain water and is provided with a drain hole; the drain valve assembly comprises a valve element, a transmission rod mechanism, an elastic positioning member, and an elastic reset member; the valve element is provided with a sealing position and a drain position; a first end of the transmission rod mechanism drives the valve element to move; during the rotation process of the inner drum, the driving apparatus can selectively toggle a second end of the transmission rod mechanism so as to drive the transmission rod mechanism to rotate around a center line of rotation; the elastic positioning member can maintain the valve element at the sealing position or the drain position; and the elastic reset member can drive at least the second end of the transmission rod mechanism to reset. According to the laundry treatment device in the embodiments of the present application, regardless of the rotational speed of the inner drum, the switching of the valve element between the sealing position and the drain position can be implemented by rotating the transmission rod mechanism, thereby facilitating drainage, and achieving high reliability.
