Abstract

A laundry dryer includes a dry drum in which laundry is loaded, a noise reduction member mounted on an outer circumference of the dry drum to absorb vibration/noise, a lift attached on an inner circumference of the dry drum to lift the laundry, a coupling member coupling the noise reduction member and/or the lift to the dry drum, and a belt disposed around the dry drum.

Claims

1. A laundry dryer comprising:

a dry drum in which laundry is loaded;

at least one noise reduction member mounted on an outer circumference of the dry drum to absorb vibration/noise;

a lift attached on an inner circumference of the dry drum to lift the laundry;

a coupling member coupling the noise reduction member and/or the lift to the dry drum; and

a belt disposed around the dry drum,

wherein the dry drum is provided with a concave portion to prevent a head portion of the coupling member from interfering with the belt, and the noise reduction member is formed of a material selected from the group consisting of stainless steel plated with zinc or tin rubber and plastic.

2. The laundry dryer according to claim 1, further comprising an adhesive layer disposed between the noise reduction member and the dry drum.

3. The laundry dryer according to claim 1, wherein the noise reduction member is attached on the dry drum by adhesive.

4. The laundry dryer according to claim 1, wherein the noise reduction member is attached on the dry drum by a double-sided tape.

5. The laundry dryer according to claim 1, wherein the coupling member is one of a screw and a pin.

6. The laundry dryer according to claim 1, wherein the noise reduction member is formed of strength member having a curvature identical to that of the outer circumference of the drum.

11. The laundry dryer according to claim 1, further comprising an insert pad interposed between the noise reduction member and the dry drum to further absorb vibration/noise.

7. A laundry dryer comprising:

a dry drum in which laundry is loaded;

at least one noise reduction member mounted on an outer circumference of the dry drum to absorb vibration/noise;

a lift attached on an inner circumference of the dry drum to lift the laundry;

a coupling member coupling the noise reduction member and/or the lift to the dry drum; and

a belt disposed around the dry drum,

wherein the noise reduction member is provided with a coupling end portion of different width than a main portion of the noise reduction member.

8. The laundry dryer according to claim 7, wherein the coupling end portion is provided with a coupling hole in which the coupling member is inserted.

9. The laundry dryer according to claim 7, wherein a width of the coupling end portion is less than that of the main portion of the noise reduction member.

10. The laundry dryer according to claim 7, wherein a border between the coupling end portion and the main portion of the noise reduction member is rounded.

12. A laundry dryer comprising:

a dry drum;

a lift attached on an inner circumference of the dry drum to move the laundry;

a strip-shaped noise reduction member disposed around an outer circumference of the dry drum to absorb vibration, the noise reduction member being provided at both end portions with a coupling element; and

a coupling members for coupling the end portions of the noise reduction member to physically separated portions of the outer circumference of the dry drum.

13. The laundry dryer according to claim 12, wherein a width of the coupling end is at least identical to or less that that of the end of the noise reduction member.

14. The laundry dryer according to claim 12, wherein a border between the coupling end portion and the main portion of the noise reduction member is rounded.

15. The laundry dryer according to claim 12, wherein the coupling element is a coupling hole in which the coupling member is inserted.

16. The laundry dryer according to claim 12, further comprising an insert pad interposed between the noise reduction member and the dry drum to further absorb vibration/noise.

17. The laundry dryer according to claim 16, further comprising an adhesive layer between the insert pad and the noise reduction member.

18. The laundry dryer according to claim 16, wherein the insert pad is attached to the noise reduction member by adhesive or a both-sided tape.

19. The laundry dryer according to claim 12, wherein the noise reduction member is disposed on a portion of the outer circumference of the dry drum.

20. The laundry dryer according to claim 12, wherein the noise reduction member is formed of two sections attached on each half of the outer circumference to be offset with respect to each other.

21. The laundry dryer according to claim 12, wherein the noise reduction member and the lift is are integrally coupled to each other by the coupling member.

22. The laundry dryer according to claim 12, wherein at least one coupling member couples only the noise reduction member and the dry drum.

23. The laundry dryer according to claim 12, wherein the noise reduction member has a meander line shape.

24. A laundry dryer comprising:

A dry drum in which laundry is loaded;

at least one noise reduction member mounted on an outer circumference of the dry drum to absorb vibration/noise;

a lift attached on an inner circumference of the dry drum to lift the laundry;

a coupling member coupling the noise reduction member and/or the lift to the dry drum, and

a belt disposed around the dry drum, wherein the noise reduction member is provided at a top with a plurality of embossments.

25. A laundry dryer comprising:

a dry drum in which laundry is loaded;

at least one noise reduction member mounted on an outer circumference of the dry drum to absorb vibration/noise;

a lift attached on an inner circumference of the dry drum to lift the laundry;

a coupling member coupling the noise reduction member and/or the lift to the dry drum, and

a belt disposed around the dry drum, wherein the coupling end includes one or more first projections extending from a first end of the noise reduction member and having a width that is increased as it goes away from a body portion, and a second projection is formed on a second end of the noise reduction member, the second projection being interlocked with an insertion portion defined by the first projections.

26. A laundry dryer comprising:

a dry drum in which laundry is loaded;

a lift mounted in an inner circumference of the drum in a direction of an axis, the lift being provided with a coupling guide projection;

a noise reduction member mounted on an outer circumference of the dry drum, the noise reduction member having an end portion with at least one coupling hole in which a coupling member is inserted; and

wherein the noise reduction member is provided with a hook hole in which the bent end of the coupling guide projection is inserted.

27. The laundry dryer according to claim 26, wherein the hook hole has a length identical to or greater than that of the bent end of the coupling guide projection.
