A laundry treating apparatus includes a drum and a lifter disposed on an inner circumferential surface of the drum and configured to rotate with the drum. The lifter includes a lifter frame installed on the inner circumferential surface of the drum and a frame cover coupled to the lifter frame. The lifter frame includes a frame base coupled to the inner circumferential surface, a frame upper plate having a first water flow through-hole, and a frame sidewall that connects the frame upper plate to the frame base and that defines a second water flow through-hole. The frame cover includes a cover upper plate having a water flow discharge hole configured to discharge, into the drum, washing water having passed through at least one of the first water flow through-hole or the second water flow through-hole, and a cover sidewall that extends from the cover upper plate to the frame base.

Laundry treating apparatus

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.

A laundry treating apparatus includes: a drum configured to receive laundry and to rotate about a rotation axis that extends in a front-rear direction of the laundry treating apparatus; and a lifter disposed on an inner circumferential surface of the drum and configured to rotate about the rotation axis based on rotation of the drum. The lifter includes: a lifter upper plate portion spaced apart from the inner circumferential surface of the drum, a lifter sidewall portion that is made of metal and that extends from lifter upper plate portion toward the inner circumferential surface of the drum, and a side protrusion that protrudes from an outer surface of the lifter sidewall portion. The lifter sidewall portion has a lower end coupled to the inner circumferential surface of the drum and an upper end connected to the lifter upper plate portion.

A laundry treating apparatus includes: a drum defining a mounting slot and a lifter coupled to the mounting slot and disposed on an inner circumferential surface of the drum. A lifter frame includes: a frame base coupled to the inner circumferential surface; a frame upper plate; a frame sidewall that connects the frame upper plate to the frame base and that defines a lateral through-hole; and an insertion protrusion configured to be inserted into the mounting slot. The insertion protrusion includes a vertical portion that extends downward from a bottom surface of the frame base to the frame base and a catching portion that is curved from a lower end of the vertical portion toward an inside of the periphery of the frame base. A projection plane of the catching portion onto the frame base is positioned within a projection plane of the lateral through-hole onto the frame base.

A laundry treating apparatus includes: a drum and a lifter that is disposed on an inner circumferential surface of the drum and that is configured to rotate with the drum. The lifter includes a lifter frame coupled to the drum and a frame cover that covers the lifter frame. The lifter frame includes: a frame base coupled to the inner circumferential surface of the drum; a frame upper plate spaced apart from the frame base in a direction toward an inside of the drum; a frame sidewall that connects the frame upper plate to the frame base; and a spacer that protrudes from the frame upper plate toward an inner surface of the frame cover and that allows the inner surface of the frame cover to be spaced apart from the frame upper plate.
