The present invention includes a tub, a drum rotatably provided within the tube, and a lift provided within the drum, the lift including a base part detachably assembled to an inner surface of the drum and a cover part detachably assembled to the base part to enable a replacement of a washing ball, wherein an exposing hole is provided to a surface of the cover part to expose a portion of the washing ball and wherein a width of the cover part is decreased toward a front side of the cover part from a rear side of the cover part.

Claims

1. A drum type washer comprising:

a tub;

a drum rotatably provided within the tube; and

a lift provided within the drum, the lift comprising;

a base part detachably assembled to an inner surface of the drum; and

a cover part detachably assembled to the base part to enable a replacement of a washing ball, wherein an exposing hole is provided to a surface of the cover part to expose a portion of the washing ball and wherein a width of the cover part is decreased toward a front side of the cover part from a rear side of the cover part.

2. The drum type washer of claim 1, wherein the cover part has an upwardly convex shape to cover an upper side of the base part.

3. The drum type washer of claim 1, wherein a guide piece is provided to either an edge of the base part or a lower edge of the cover part and wherein a guide recess is provided to either the lower edge of the cover part or the edge of the base part to have the guide piece slid to be inserted therein.

4. The drum type washer of claim 3, wherein the base part and the cover part are locked to each other by a locking bolt.

5. The drum type washer of claim 1, wherein a hook is provided to either a lower surface of the base part or an inner circumference of the drum and wherein a recess to have the hook inserted therein is provided to the inner circumference of the drum or the lower surface of the base part.

6. The drum type washer of claim 1, wherein the base part is locked by a locking bolt to be fixed to an inner circumference of the drum.

7. The drum type washer of claim 1, wherein a rear end of the base part is upwardly projected and wherein the rear end of the base part is locked to a rear side of the drum by a locking bolt.

8. The drum type washer of claim 7, wherein a solidity-reinforcing rib is provided to the rear end of the base part.

9. The drum type washer of claim 1, further comprising a supporter detachably provided to a lower side of the cover part, the supporter having a support recess rotatably supporting a lower portion of the washing ball.

10. The drum type washer of claim 9, wherein a hook part is provided to both ends of the supporter, wherein a locking part is provided to the lower side of the cover part, and wherein the hook part is fitted into the locking part to be fixed thereto.

11. The drum type washer of claim 10, the locking part comprising:
