A laundry washing machine comprising: a cabinet, a washing tub housed inside the cabinet, a drum rotatably housed inside the tub, and an electric liquid supplying device mounted in or on the drum and configured for dispensing a liquid in an inner region of the drum. The invention is also related to a method for operating such a laundry washing machine.

An inner drum cover is provided at a drum opening of an inner drum of a washing machine, the inner drum cover is used to open or close the drum opening, so that the inner drum forms a closed container after the drum opening is closed by the inner drum cover. The inner drum can perform washing after the inner drum cover is correspondingly fastened to the drum opening, so that clothes only come into contact with washing water in the sealed inner drum in a washing process. In this way, a case in which the clothes are contaminated because washing water between the inner drum and an outer drum flows into the inner drum is avoided, washing cleanliness of the washing machine is greatly improved, and incomplete washing of the clothes caused by contamination of the washing water between the inner drum and the outer drum is avoided.

A laundry washing machine having a cabinet, a washing tub housed inside the cabinet, a drum rotatably housed inside the cabinet, an electric additive treating device mounted in/on the drum and configured for treating a washing and/or rinsing additive loaded within the drum in such a way to generate within the drum a solution of washing and/or rinsing additive water. A method for operating such a laundry washing machine is also provided.

A laundry lifting device for a washing machine includes a body with an accommodating chamber, a water inlet arranged in the body and communicated with the accommodating chamber, and a centrifugal drainage assembly arranged in the accommodating chamber. The centrifugal drainage assembly includes a sealing plunger capable of doing reciprocating motion and an elastic piece for elastically resetting the sealing plunger, the body is provided with a plunger base for installing the sealing plunger, and the elastic piece is kept limited in the plunger base in the reciprocating motion process of the sealing plunger. The elastic piece is installed in the plunger base in the sealing mode, and the elastic piece is kept limited in the plunger base in the reciprocating motion of the sealing plunger. So thread scraps are prevented from being hung on the elastic piece.

A laundry treating apparatus includes: a drum, a first lifter disposed on an inner circumferential surface of the drum, and a second lifter that is disposed on the inner circumferential surface of the drum at a position rearward of the first lifter. Each of the first lifter and the second lifter includes at least one insertion protrusion. The drum defines: a first group of one or more mounting slots in a first area of the drum; and a second group of one or more mounting slots in a second area of the drum. The second area is disposed rearward relative to the first area and overlaps with at least a portion of the first area of the drum, and the at least one insertion protrusion is configured to selectively insert into the one or more mounting slots in the first group or the second group.
