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 mounted 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 insertion of the filter assembly into the filter guide, the filter insertion detecting device comprising an electrode sensor configured to move in response to insertion of the filter assembly into the filter guide and generate a contact signal based on movement that occurs in response to insertion of the filter assembly into the filter guide,
wherein the electrode sensor comprises:
a printed circuit board terminal mounted at the filter guide and connected to a printed circuit board; and
a connection terminal mounted at the filter cover and configured to connect to the printed circuit board terminal based on insertion of the filter assembly into the filter guide and disconnect from the printed circuit board terminal based on removal of the filter assembly from the filter guide.

2. The apparatus of claim 1 , wherein the printed circuit board terminal comprises first and second terminals connected to a circuit of the printed circuit board.

3. The apparatus of claim 2 , wherein, based on insertion of the filter assembly into the filter guide, the connection terminal is configured to contact the first and second terminals to electrically connect the circuit of the printed circuit board.

4. The apparatus of claim 3 ,
wherein, based on rotation of the filter cover caused by insertion of the filter assembly into the filter guide, the connection terminal is configured to contact the first and second terminals to electrically connect the circuit of the printed circuit board.
