Abstract

A lifter for a laundry treating apparatus includes a first member mounted at an inner side of a drum; and a second member mounted on the first member and protruded toward an inside of the drum, wherein the first member includes a hook protruded and formed along a circumference of the first member, at least part of which is disposed to cover an inner circumferential surface of the drum when inserted into a fastening hole of the drum and then slid in one direction; and a shield protruded and formed at an inner side of the first member and configured to completely cover the fastening hole when the hook is, inserted into the fastening hole and then slid in one direction.

First claim

What is claimed is:

1 . A lifter for a laundry treating apparatus, the lifter comprising:
a lifter base to be coupled to an inner side of a drum extending along an axial direction; and a lifter top mounted on the lifter base, wherein the lifter base includes:
a plurality of hooks provided along an inner circumference of the lifter base, and at least part of each hook contacts an inner surface of the drum when inserted into a fastening hole of the drum and then slid in a first direction; and
a shield provided at an inner side of the lifter base and configured to completely cover the fastening hole when the at least one hook adjacent to the shield is inserted into the fastening hole and then slid in the first direction.

2 . The lifter of claim 1 , wherein the shield is formed at a first side of the lifter base corresponding to a rotational direction of the drum to prevent washing water from being discharged through the corresponding fastening hole.

3 . The lifter of claim 2 , wherein a plural of shields are spaced apart along the first side of the lifter base.

4 . The lifter of claim 2 , wherein a second side of the lifter base is configured to cover only part of the fastening hole when a hook is inserted into the fastening hole and then slid in the first direction to allow the introduction of washing water.

5 . The lifter of claim 1 , wherein the lifter base includes a washing water inlet overlapping with part of a hole formed on the drum to introduce washing water into the lifter.

6 . The lifter of claim 5 , wherein the washing water inlet includes a plurality of washing water inlet holes separated from one another along a direction in parallel to a rotational axis of the washer drum.

7 . A lifter for a laundry treating apparatus, the lifter comprising:
a lifter base to be coupled to an inner side of a drum extending in an axial direction; and a lifter top mounted on the lifter base, wherein the lifter top includes:
a body extending toward the center of the drum to accommodate washing water therein; and
a plurality of tabs located along a lower circumference of the body.

8 . The lifter of claim 7 , wherein a plurality of mounting holes are formed on the lifter base into which the plurality of tabs are inserted couple the lifter top to the lifter base.

9 . The lifter of claim 8 , wherein a tab of the lifter top is inserted into a mounting hole of the lifter base and the tab is bent to secure the lifter base to the lifter top.

10 . The lifter of claim 7 , wherein the lifter top includes a plurality of washing water discharge holes located at an upper portion of the body and formed along a first direction to discharge washing water having been received in the body from an outside of the drum.

11 . The lifter of claim 1 , wherein a screw insertion hole is formed at one side of the lifter base to fix the lifter base to an inner surface of the drum by screw fastening.

12 . The lifter of claim 1 , wherein the lifter base is formed of stainless steel, and the lifter top is formed of plastic.

13 . A lifter for a laundry treating apparatus, the lifter comprising:
a lifter base to be couples to an inner side of a drum extending in an axial direction; and a lifter top mounted on the lifter base, wherein the lifter base includes:
a plurality of hooks formed along a first lateral side and a second lateral side of the lifter base, the plurality of hooks configured to latch the lifter base to an inner surface of the drum when inserted into corresponding coupling holes, of the drum and slid in a first direction; and
a plurality of shields formed only at the first lateral side of the lifter base and configured to completely cover the fastening hole when the plurality of hooks are inserted into the plurality of coupling holes and then slid in the first direction.

14 . The lifter of claim 13 , wherein the first lateral side of the lifter base is a rear side with respect to a rotation direction of the drum.

15 . The lifter of claim 13 , wherein the lifter base includes a washing water inlet including a plurality of washing water inlet holes spaced apart along a bottom surface of the lifter base.

16 . The lifter of claim 13 , wherein the lifter top includes a plurality of tabs configured to be inserted into a plurality of mounting holes formed at the lifter base to secure the lifter top to the lifter base.

17 . The lifter of claim 13 , wherein the lifter top includes a plurality of washing water discharge holes facing the center of the drum to discharge washing water from within the lifter to the drum.
