摘要： The present invention discloses a laundry lifting device for a washing machine, a centrifugal drainage mechanism and a washing machine. The laundry lifting device comprises: a lifting shell internally provided with a cavity with an opening; and a centrifugal drainage mechanism installed inside the lifting shell, wherein an initial state of the centrifugal drainage mechanism is a closed state, and the centrifugal drainage mechanism can be operated for drainage under a centrifugal force. The cavity of the lifting shell is separated by an independently enclosed installation cavity, and the centrifugal drainage mechanism is at least partially installed in the installation cavity. As to the laundry lifting device of the present invention, the centrifugal drainage mechanism is installed in the enclosed installation cavity independently separated out in the lifting shell, so water flow inside the inner drum does not enter into the installation cavity. The centrifugal drainage mechanism is in an environment free of thread debris. Thereby the possibility of adhering and winding thread debris on the centrifugal drainage mechanism is fundamentally avoided, and the reliability of the centrifugal drainage mechanism is effectively ensured during operation.

摘要： A water inlet structure for a drum washing machine and the drum washing machine are provided. The water inlet structure comprises a support frame (1), a water inlet pipe (10) and a buffer structure (4), wherein an water outlet of the water inlet pipe (10) is provided with a water passing chamber radially extending, the water passing chamber is installed on the on the support frame (1) by the buffer structure (4). By setting a buffer structure (4) between the support frame (1) and the water passing chamber, the support frame (1) is flexible connected with the water passing chamber by the buffer structure (4), so that the support frame (1) can move relative to the water passing chamber and the deformation force of the outer cylinder (8) is buffered. The deformation force of the outer cylinder (8) is prevented from being transmitted to the water passing chamber formed by the bearing seat (2) and the water outlet adaptor (3), so as to avoid the bearing seat and the oil seal from being deformed. The noise and water leakage of the drum washing machine are further solved.
