Abstract

A clothes treating apparatus includes a filter insertion detecting device that detects whether a filter has been inserted in the clothes treating apparatus. The filter insertion detecting device, which is installed in a clothes drying machine or the like, may be moved in response to insertion of a filter assembly to generate a contact signal that indicates insertion of the filter assembly.

First claim

What is claimed is:

1. A clothes treating apparatus comprising:
a drum defining a cavity that receives clothes to be dried;
a cabinet that houses the drum and that defines an opening to enable loading of clothes into the drum and unloading of clothes from the drum;
a filter assembly configured to filter foreign materials included in air discharged from the drum;
a filter guide that defines a conduit that receives at least a portion of the filter assembly;
a filter cover rotatably installed at the filter guide and configured to open and close the conduit defined by the filter guide based on insertion of the filter assembly into the filter guide and removal of the filter assembly from the filter guide; and
a filter insertion detecting device configured to detect the insertion of the filter assembly into the filter guide based on rotation of the filter cover caused by the insertion of the filter assembly into the filter guide,
wherein the filter insertion detecting device is configured to generate a contact signal caused by a magnetic force applied to the filter insertion detecting device in response to the rotation of the filter cover.

2. The apparatus of claim 1 , wherein the filter insertion detecting device comprises:
a lead switch comprising first and second terminals spaced apart from each other in an overlapping manner, the lead switch being electrically connected when the first and second terminals contact each other, and
a magnet configured to apply a magnetic force that causes the first and second terminals of the lead switch to contact each other.

3. The apparatus of claim 2 , wherein the first and second terminals contact each other by the magnetic force of the magnet based on the rotation of the filter cover caused by the insertion of the filter assembly into the filter guide.

4. The apparatus of claim 3 , wherein a reed switch is mounted at the filter guide, and
wherein the magnet is mounted on the filter cover.

5. The apparatus of claim 2 , wherein the first and second terminals are disconnected from each other within a hermetic space.

6. The apparatus of claim 1 , wherein the filter cover includes hinge shafts protruding from both sides thereof, each of the hinge shafts being inserted into a corresponding hinge shaft hole provided on a side wall of the filter guide.

7. The apparatus of claim 6 , wherein the filter cover is configured to open and close the conduit defined by the filter guide as the hinge shaft is rotated in an inserted state in the hinge shaft hole.

8. The apparatus of claim 7 , further comprising:
a torsion spring disposed at the hinge shaft and provide an elastic restoring force to close the conduit.

9. The apparatus of claim 8 , wherein the filter cover is configured to be stopped by the filter guide and maintain a closed state of the conduit by the torsion spring when the filter assembly is removed from the filter guide.

10. A clothes treating apparatus comprising:
a drum defining a cavity that receives clothes to be dried;
a cabinet that houses the drum and that defines an opening to enable loading of clothes into the drum and unloading of clothes from the drum;
a filter assembly configured to filter foreign materials included in air discharged from the drum;
a filter guide that defines a conduit that receives at least a portion of the filter assembly;
a filter cover rotatably installed at the filter guide and configured to open and close the conduit defined by the filter guide based on insertion of the filter assembly into the filter guide and removal of the filter assembly from the filter guide; and
a filter insertion detecting device configured to detect the insertion of the filter assembly into the filter guide based on rotation of the filter cover caused by the insertion of the filter assembly into the filter guide,
wherein the filter insertion detecting device includes a switch configured to be pressed and generate a contact signal in response to the rotation of the filter cover caused by the insertion of the filter assembly into the filter guide.

11. The apparatus of claim 10 , wherein the switch comprises:
a button configured to electrically connect a circuit of a printed circuit board based on pressure applied to the button and electrically disconnect the circuit of the printed circuit board based on release of pressure applied to the button; and
a pressing member configured to press the button based on the rotation of the filter cover caused by the insertion of the filter assembly into the filter guide.

12. The apparatus of claim 11 , wherein the pressing member comprises:
a pressing portion configured to press the button based on an external force applied to the pressing portion due to the rotation of the filter cover caused by the insertion of the filter assembly into the filter guide; and
an elastic portion configured to release the button based on the external force being released due to removal of the filter assembly from the filter guide.

13. The apparatus of claim 11 , wherein the switch is mounted at the filter guide, and
wherein the filter cover is configured to press the pressing member based on the rotation of the filter cover caused by the insertion of the filter assembly into the filter guide.

14. The apparatus of claim 11 , further comprising a pressing plate provided at the filter cover and configured to press the pressing member when the filter cover is rotated as the filter assembly is inserted into the filter guide.

15. The apparatus of claim 10 , wherein the filter cover includes hinge shafts protruding from both sides thereof, each of the hinge shafts being inserted into a corresponding hinge shaft hole provided on a side wall of the filter guide, and
wherein the filter cover is configured to open and close the conduit defined by the filter guide as the hinge shaft is rotated in an inserted state in the hinge shaft hole.

16. The apparatus of claim 15 , further comprising a torsion spring disposed at the hinge shaft and configured to provide an elastic restoring force to close the conduit, and
wherein the filter cover is configured to be stopped by the filter guide and maintain a closed state of the conduit by the torsion spring when the filter assembly is removed from the filter guide.

17. A clothes treating apparatus comprising:
a drum defining a cavity that receives clothes to be dried;
a cabinet that houses the drum and that defines an opening to enable loading of clothes into the drum and unloading of clothes from the drum;
a filter assembly configured to filter foreign materials included in air discharged from the drum;
a filter guide that defines a conduit that receives at least a portion of the filter assembly;
a filter cover rotatably installed at the filter guide and configured to open and close the conduit defined by the filter guide based on insertion of the filter assembly into the filter guide and removal of the filter assembly from the filter guide; and
a filter insertion detecting device configured to detect the insertion of the filter assembly into the filter guide based on rotation of the filter cover caused by the insertion of the filter assembly into the filter guide,
wherein the filter cover includes hinge shafts protruding from both sides thereof, each of the hinge shafts being inserted into a corresponding hinge shaft hole provided on a side wall of the filter guide.

18. The apparatus of claim 17 , wherein the filter cover is configured to open and close the conduit defined by the filter guide as the hinge shaft is rotated in an
