Abstract

A clothes dryer comprises a body, a first drying container installed in the body and configured to include a rotary drum configured to be rotatable, and a second drying container installed in the body but separated from the first drying container, and the second drying container includes an electrode plate configured to include a plurality of electrode regions, a controller configured to select an electrode region where an electric field is to be applied, among the plurality of electrode regions and an electric field is applied to the electrode region selected by the controller.

First claim

The invention claimed is:

1. A clothes dryer comprising:
a body;
a first drying container installed in the body and configured to include a rotary drum configured to be rotatable; and
a second drying container installed in the body but separated from the first drying container, the second drying container comprising
an electrode plate including a first electrode plate installed on one surface of the second drying container and a second electrode plate installed on another surface of the second drying container facing the first electrode plate, the electrode plate including a plurality of electrode regions;

a controller configured to select an electrode region where an electric field is to be applied, among the plurality of electrode regions; and
an electric field applier configured to apply an electric field to the electrode region selected by the controller.

2. The clothes dryer of claim 1 , wherein,
the second drying container further comprises a door configured to open and close an inlet formed in an upper surface of the second drying container, and
the first electrode plate is installed on a lower surface of the door, and the second electrode plate is installed on an upper surface of a lower portion of the second drying container.

3. The clothes dryer of claim 2 , wherein,
the first electrode plate is formed of cathodes and the second electrode plate is formed of anodes.

4. The clothes dryer of claim 1 , wherein,
the electrode plate comprises a first electrode region arranged in a center portion of the electrode plate and a second electrode region surrounding an outside of the first electrode region.

5. The clothes dryer of claim 1 , wherein,
the second drying container further comprises an impedance detector configured to detect an impedance of the plurality of electrode regions,
wherein the controller selects an electrode region where an electric field is to be applied, based on the impedance of the plurality of electrode regions.

6. The clothes dryer of claim 5 , wherein,
the electrode plate comprises a first electrode region arranged in a center portion of the electrode plate and a second electrode region surrounding an outside of the first electrode region,
wherein the controller allows the electric field applier to apply an electric field to the first electrode region when a capacitance of the first electrode region is less than a predetermined reference value, and the controller allows the electric field applier to apply an electric field to the first electrode region and the second electrode region when a capacitance of the second electrode region is less than the predetermined reference value.

7. The clothes dryer of claim 1 , further comprising:
a control panel configured to receive a command for applying an electric field to at least one electrode region among the plurality of electrode regions, from a user,
wherein the controller selects an electrode region where an electric field is to be applied, based on the electric field application command.

8. The clothes dryer of claim 1 , wherein,
the second drying container further comprises an electrode plate mover configured to move the electrode plate.

9. The clothes dryer of claim 8 , wherein,
the second drying container further comprises an impedance detector configured to detect an impedance of the electrode plate,
wherein the controller controls the electrode plate mover based on a value detected by the impedance detector.

10. The clothes dryer of claim 8 , further comprising:
a control panel configured to receive an electrode plate movement command, from a user,
wherein the controller allows the electrode plate mover to move the electrode plate based on the electrode plate movement command.

11. The clothes dryer of claim 1 , wherein,
the electrode plate comprises a plurality of holes.

12. The clothes dryer of claim 1 , wherein,
the electrode plate is installed on a side surface of the second drying container.

13. The clothes dryer of claim 1 , wherein,
the electrode plate comprises a plurality of electrode plates configured to divide an empty space of the second drying container into a plurality of regions.

14. The clothes dryer of claim 13 , wherein,
the plurality of electrode plates is formed in the form of a propeller with respect to an upper surface of the second drying container.
