Lint removing apparatus and clothes dryer having the same
A clothes dryer including a cabinet, a drum rotatably supported in the cabinet, a supply port configured to guide air into the drum, an exhaust port configured to guide the air in the drum to an outside of the drum, and a lint removing apparatus configured to remove lint from the air passing through the exhaust port. Where the lint removing apparatus includes a lint filter configured to capture lint, a rotation member rotatably installed to scrape and collect the lint captured in the lint filer, a driving device configured to generate power, a first coupler connected to the driving device to receive the power from the driving device, and a second coupler coupled to the first coupler to transmit the power to the rotation member.
1. A clothes dryer comprising:
a cabinet;
a drum rotatably supported in the cabinet;
a supply port configured to guide air into the drum;
an exhaust port configured to guide the air in the drum to an outside of the drum; and
a lint removing apparatus configured to remove lint from the air passing through the exhaust port,
wherein the lint removing apparatus includes:
a lint filter configured to capture lint,
a screw conveyor rotatably installed to scrape and collect the lint captured in the lint filter,
a driving device including a motor, and configured to generate power,
a first coupler connected to the driving device to receive the power from the driving device,
a second coupler coupled to the first coupler to transmit the power to the screw conveyor,
a holder in contact with the second coupler, and configured to move the second coupler so that the first coupler and the second coupler are coupled to or separated from each other, and
an elastic member configured to elastically press the holder so that the first coupler and the second coupler are in a disengaged state to an engaged state.
2. The clothes dryer of claim 1 , wherein:
the lint removal apparatus further includes a first rotation shaft to which the first coupler is coupled and a second rotation shaft to which the second coupler is coupled, and
the elastic member is disposed between the holder and the screw conveyor, and configured to elastically press the holder.
3. The clothes dryer of claim 1 , wherein the lint removing apparatus further includes a frame member configured to surround the screw conveyor, and
wherein the holder is rotatably coupled to the frame member.
4. The clothes dryer of claim 1 , wherein the elastic member is disposed between a frame member and the second coupler so that the elastic member presses the second coupler and the holder in the disengaged state to the engaged state.
5. The clothes dryer of claim 1 , wherein the motor is rotatable in both directions.
