Abstract

An apparatus for laundry treatment includes: a cabinet defining an entrance at one side, a drum defining a space for receiving laundry therein, a duct connected to the drum, a fan configured to move air in the drum into the duct, a heat exchange part including a heat absorption part configured to remove moisture from the air moved into the duct and a heating part configured to heat the air having passed through the heat absorption part, a compressor configured to increase a temperature of the air by compressing a refrigerant having passed through the heat absorption part, a water collecting part configured to receive the moisture removed by the heat exchange part, and a soundproof panel provided at a bottom of a base part that is located at a bottom of the cabinet.

First claim

What is claimed is:

1. An apparatus for laundry treatment, comprising:
a cabinet defining an entrance at one side and a base part at a bottom;
a drum defining a space for receiving laundry therein;
a duct connected to the drum;
a fan provided in a first area of the base part and configured to move air in the drum into the duct;
a heat exchange part including a heat absorption part configured to remove moisture from the air moved into the duct and a heating part configured to heat the air having passed through the heat absorption part;
a compressor provided in the first area of the base part and configured to increase a temperature of the air passing through the heat exchange part by compressing a refrigerant having passed through the heat absorption part;
a water collecting part configured to receive the moisture removed by the heat exchange part; and
a soundproof panel configured to reduce noise and provided at the first area of a bottom of the base part that is located at the bottom of the cabinet,
wherein the water collecting part comprises a drain pump provided in the first area and configured to remove the moisture from the heat exchange part,
wherein a portion of the base part corresponding to the drain pump is projected in a bottom direction,
wherein the soundproof panel comprises an opening defined in an area corresponding to the portion of the base part projected in the bottom direction, and
wherein the portion of the base part corresponding to the drain pump passes through the opening.

2. The apparatus of claim 1 , wherein the base part comprises a second area having a bottom side exposed without overlapping with the soundproof panel.

3. The apparatus of claim 1 , wherein the entrance is located at a front side of the cabinet, and wherein the first area is located at a rear side of the base part.

4. The apparatus of claim 1 , wherein the soundproof panel includes a metallic material and comprises a bead projected from a first side of the soundproof panel to a second side of the soundproof panel, the second side being opposite from the first side.

5. The apparatus of claim 4 , wherein the bead extends to form a closed curve.

6. The apparatus of claim 5 , wherein the bead extends while maintaining a uniform distance from an outline of the soundproof panel.

7. The apparatus of claim 1 , further comprising a sound absorption material attached to a top side of the soundproof panel confronting the base part.

8. The apparatus of claim 7 , wherein the sound absorption material comprises polyethylene terephthalate (PET) and includes a fibrous tissue.

9. The apparatus of claim 7 , wherein the sound absorption material has a thickness between 4 mm and 10 mm.

10. The apparatus of claim 7 , wherein a thickness of the sound absorption material is thinner than a space between the base part and the soundproof panel.

11. The apparatus of claim 1 , wherein the soundproof panel has a thickness between 0.4 mm and 1.0 mm.

12. The apparatus of claim 1 , wherein the soundproof panel comprises a metallic material, and wherein the base part comprises injection-molded plastic.

13. The apparatus of claim 1 , further comprising:
a plurality of support legs projected from the bottom of the base part,
wherein the base part not configured to contact with a floor.

14. The apparatus of claim 13 , wherein the soundproof panel is thinner than a height of the plurality of support legs.

15. The apparatus of claim 1 , wherein the fan is included in the heat exchange part.

16. The apparatus of claim 1 , wherein the heat exchange part is provided within the duct.

17. The apparatus of claim 1 , wherein the fan is disposed at an opposite side of the entrance.

18. The apparatus of claim 1 , wherein the compressor is disposed at an opposite side of the entrance.

19. The apparatus of claim 1 , wherein the soundproof panel is configured to reduce the noise from at least one of the compressor or the fan.

20. The apparatus of claim 1 , wherein the soundproof panel is configured to correspond to a shape of the first area.
