Document Type and Number:
WIPO Patent Application WO/2018/095309
Kind Code:
A1
Abstract:
A cleaning-free water-saving washing machine and a control method therefor. The cleaning-free water-saving washing machine comprises an outer drum (100), an inner drum (200) rotatably disposed in the outer drum (100), and an inner drum shaft (702) connected to the inner drum (200) and used for driving the inner drum (200) to rotate. In the washing/rinsing process, the inner drum (200) serves as a water containing drum. A water discharging hole (204) is formed in the bottom of the inner drum (200). A water sealing device is disposed on the outer side of the bottom of the inner drum (200) and comprises a water sealing assembly and a pull ring assembly (500) that are separately sleeved outside the inner drum shaft (702). The water sealing assembly is mounted at the bottom of the inner drum (200) and can rotate along with the inner drum (200). The pull ring assembly (500) and the water sealing assembly can be connected in a relatively rotating manner, and the pull ring assembly (500) can pull the water sealing assembly to move along the axial direction of the inner drum (200) to open/close the water discharging hole. One end of the water sealing assembly is sealedly connected to the inner drum (100), and the other end of the water sealing assembly is sealedly connected/disconnected to the outer drum (100) under the pull of the pull ring assembly (500). The cleaning-free water-saving washing machine also comprises a water level detection device, a detection end of which communicates with the inside of the water sealing assembly. The cleaning-free water-saving washing machine implements water level detection in the water intake process.
