Abstract

A laundry treating apparatus may include a cabinet, a drum rotatably installed in the cabinet, a heat exchanger disposed in the cabinet and receiving air from the drum, and a cleaning device disposed in the cabinet and moved by an external force in a first direction to remove lint accumulated on the heat exchanger. The lint may be simply removed from the heat exchanger and air may smoothly flow through the heat exchanger, thus improving performance of the laundry treating apparatus.

First claim

What is claimed is:

1. A clothes treating apparatus, comprising:
a cabinet;
a drum rotatably installed in the cabinet;
a heat exchanger provided in the cabinet and configured to cool air received from the drum;
an opening provided in a side surface of the cabinet that faces the heat exchanger; and
a cleaning device configured to be inserted into or withdrawn through the opening so as to be detachably coupled to the cabinet and driven by an external force to remove debris accumulated on the heat exchanger, the cleaning device including:
a supporting device configured to cover the opening and having a through hole provided in a surface thereof that faces the heat exchanger;
a handle exposed to an outside of the cabinet to receive an external force manually applied thereto;
a cleaning end that makes contact with the heat exchanger and removes debris accumulated on the heat exchanger while moving in a predetermined direction; and
a connection rod that passes through the through hole to connect the handle to the cleaning end and moves with the handle in response to the external force manually applied to the handle so as to move the cleaning end in the predetermined direction.

2. The apparatus of claim 1 , wherein the connection rod is positioned within the cabinet and is configured to rotate in response to the external force manually applied to the handle.

3. The apparatus of claim 2 , wherein the heat exchanger includes a plurality of sequentially aligned radiation fins that form an air passage, and wherein the cleaning end is configured to contact and move along leading edges of the plurality of radiation fins in response to the external force manually applied to the handle so as to remove the debris accumulated on the heat exchanger.

4. The apparatus of claim 1 , wherein the handle, the connection rod, and the cleaning end are moved from an initial position in response to the external force manually applied to the handle thereof, and are restored to the initial position by an elastic force upon removal of the external force.

5. The apparatus of claim 1 , wherein the cleaning end includes a brush coupled to a brush supporter.

6. The apparatus of claim 1 , further comprising a hinge that rotatably couples the connection rod to the supporting device, wherein the connection rod is configured to rotate about the hinge in response to the external force manually applied to the handle, and the cleaning end moves in the predetermined direction opposite a direction of the external force as the cleaning end moves along leading edges of the radiation fins.

7. The apparatus of claim 1 , further comprising at least one roller rotatably fixed to the supporting device, wherein the connection rod is configured to move in a first direction corresponding to the external force in response to application of the external force to the handle and is composed of an elastic material, wherein the roller is configured to switch a moving direction of the connection rod, and the cleaning end is configured to move in the predetermined direction perpendicular to the first direction, in response to the external force, as the cleaning end moves along leading edges of the radiation fins.

8. The apparatus of claim 1 , further comprising a heat pump circulating refrigerant therethrough, the heat pump including an evaporator and a condenser to heat air supplied into the drum, wherein the heat exchanger is the evaporator.

9. The apparatus of claim 8 , further comprising a heater provided in a duct that guides air from the heat exchanger to the drum, wherein the heater is positioned downstream of the heat exchanger to further heat air heated by the heat exchanger for supply to the drum.

10. The apparatus of claim 1 , wherein the cleaning device is inserted into an air passage in which the heat exchanger is received, upstream of the heat exchanger.

11. A laundry treating apparatus, comprising:
a cabinet;
a drum rotatably installed in the cabinet;
a heat pump circulating refrigerant therethrough, the heat pump including a condenser to heat air to be supplied to the drum, and an evaporator to cool air transferred from the drum;
an opening provided in a side surface of the cabinet that faces the evaporator;
a heater to heat air transferred from the heat pump to the drum; and
a cleaning device installed in an air passage, upstream of the evaporator, the cleaning device configured to be inserted into or withdrawn through the opening so as to be detachably coupled to the cabinet, and driven by an external force to remove debris accumulated on the evaporator, wherein the cleaning device includes:
a supporting device configured to cover the opening and having a through hole provided in a surface thereof that faces the evaporator;
a manipulation portion exposed to an outside of the cabinet to receive an external force manually applied thereto;
a lint moving device that makes contact with the evaporator and is configured to remove debris accumulated on the evaporator while moving in a predetermined direction; and
a connection rod that passes through the through hole to connect the manipulation portion to the lint moving device and is configured to move with the manipulation portion in response to the external force manually applied to the manipulation portion so as to move the lint moving device in the predetermined direction.

12. The apparatus of claim 11 , wherein the supporting device partially defines the air passage.

13. The apparatus of claim 11 , wherein the evaporator is received in the air passage, and the supporting device is coupled to a pipe so as to form the air passage together with the pipe.

14. The apparatus of claim 11 , wherein the connection rod is coupled to the supporting device by a hinge or a roller that moves the connection rod to move the lint removing device in a direction that is different than that of the external force manually applied to the manipulation portion.

15. The apparatus of claim 14 , wherein the supporting device includes:
a first plate configured to cover the hole;
a second plate extended in a direction that is perpendicular to the first plate;
wherein the through hole is formed in the first plate, the connection rod is inserted through the through hole to connect the lint removing device to the manipulation portion and the hinge or roller couples the connection rod to the second plate; and
a seal provided in the through hole, between the periphery of the through hole and the connection rod.

16. The apparatus of claim 11 , wherein the manipulation portion exposed to the outside of the cabinet is a handle.
