Abstract

A clothes treating apparatus having a drying function includes: a cabinet; a drum provided within the cabinet; a heat-exchanger heat-exchanged with air exhausted from the drum; a lint filter disposed on an upstream side of the heat-exchanger with respect to flow of air exhausted from the drum to collect lint in the air; a spray tube spraying water to the lint filter to separate lint collected in the lint filter from the lint filter; and a lint collecting part at least partially provided below the lint filter or below the heat-exchanger to collect falling lint. Lint in condensate water may be collected, and thus, generation of a bad influence when condensate water is re-used may be suppressed. Also, contact between lint in drying air and the heat-exchanger may be restrained.

First claim

What is claimed is:

1. A clothes treating apparatus, comprising:
a cabinet;
a drum provided within the cabinet;
a heat-exchanger configured to exchange heat with air exhausted from the drum;
a lint filter disposed on an upstream side of the heat-exchanger with respect to a flow direction of the air exhausted from the drum and configured to collect lint in the air, wherein the lint filter includes a frame having at least one opening, and a mesh part provided in the opening and configured to allow passage of air while restraining passage of the lint;
a spray tube configured to spray water on at least one of the lint filter or the heat exchanger such that the lint collected in the lint filter is separated from the lint filter or the lint collected in the heat exchanger is separated from the heat exchanger; and
a lint collecting part provided below the lint filter and at least partially below the heat-exchanger to collect the separated lint,
wherein the lint filter is disposed to be inclined with respect to a vertical direction of the cabinet,
wherein a space between an upper portion of the mesh part and the heat-exchanger is smaller than a space between a lower portion of the mesh part and the heat-exchanger, and
wherein the spray tube includes a diffuser disposed at an upper portion of the heat-exchanger, and the diffuser includes:
a first spray part configured to spray a first portion of the water on the lint filter; and
a second spray part formed at an upstream side of an outlet of the diffuser along a flow of water of the spray tube to spray a second portion of the water on a top portion of the heat-exchanger.

2. The clothes treating apparatus of claim 1 , wherein the lint collecting part comprises a bottom part, and a side wall part extending upward from edges of the bottom part, wherein the water and the separated lint are configured to drop on the bottom part such that the bottom part allows passage of the water and restrains passage of the lint.

3. The clothes treating apparatus of claim 2 , wherein the cabinet includes a lint collecting part opening configured to allow the lint collecting part to be extracted from the cabinet.

4. The clothes treating apparatus of claim 1 , wherein the lint filter has a heat-exchanger coupling part coupled to the heat-exchanger.

5. The clothes treating apparatus of claim 1 , wherein the first spray part is provided on an upstream side of the lint filter with respect to the flow direction of the air.

6. The clothes treating apparatus of claim 5 , wherein the second spray part is provided on a downstream side of the lint filter with respect to the flow direction of the air.

7. The clothes treating apparatus of claim 6 , further comprising a diffuser disposed on a downstream side of the lint filter with respect to the flow direction of the air.

8. The clothes treating apparatus of claim 7 , wherein the outlet of the diffuser includes the first spray part and the second spray part is positioned on an upstream side of the outlet of the diffuser along a flow direction of the water in the spray tube.

9. The clothes treating apparatus of claim 8 , further comprising:
a heat pump disposed within the cabinet and including a compressor configured to compress a refrigerant, a condenser configured to condense a refrigerant, an expander configured to expand a refrigerant, and an evaporator configured to evaporate a refrigerant,
wherein the heat-exchanger includes the evaporator of the heat pump.

10. The clothes treating apparatus of claim 9 , wherein
the heat-exchanger further includes the condenser of the heat pump provided on a downstream side of the evaporator along the flow direction of the air, and
the clothes treating apparatus further comprises a condenser lint filter provided on an upstream side of the condenser along the flow direction of the air.

11. The clothes treating apparatus of claim 9 , further comprising:
a water supply part configured to supply water to the spray tube,
wherein the water supply part is configured to supply condensate water generated in the evaporator to the spray tube.

12. The clothes treating apparatus of claim 11 , wherein the water supply part includes:
a pump configured to pump the condensate water; and
a pump connection part having one side connected to the spray tube and an opposite side connected to the pump.

13. The clothes treating apparatus of claim 12 , wherein the water supply part further includes:
a water supply source connection part connected to the pump connection part and also connected to a water supply source.

14. The clothes treating apparatus of claim 1 , wherein the spray tube is provided at an upper portion of the heat-exchanger.
