Abstract

A dryer is disclosed. The dryer comprises: a body having a first opening disposed at one side thereof; a first drum rotatably disposed in the body and including a first drying chamber connected to the first opening; a first hot-air unit for supplying hot air to the inside of the first drum; a first door coupled to the body to open or close the first opening; a second drum disposed at the first door; and a second hot-air unit for supplying hot air to the inside of the second drum.

First claim

The invention claimed is:

1. A dryer comprising:
a body including a first opening in one side thereof;
a first drum rotatably disposed in the body and including a first drying chamber connected to the first opening;
a first hot-air supplier configured to supply hot air into the first drum;
a first door coupled to the body to open or close the first opening;
a second drum disposed on the first door;
a second hot-air supplier configured to supply hot air into the second drum; and
a second drum case coupled to the first door, the second drum being rotatably disposed in the second drum case,
wherein the second drum case includes an inlet port through which hot air is introduced from the second hot-air supplier and an exhaust port through which the introduced hot air is discharged,
the second drum includes a plurality of vents facing the inlet port and the exhaust port, and
the second hot-air supplier is disposed above the second drum case when the first door is in a closed state.

2. The dryer as claimed in claim 1 , wherein the first door includes a second opening passing through the first door and a second door configured to open or close the second opening, and
the second drum includes a second drying chamber connected to the second opening.

3. The dryer as claimed in claim 1 , wherein the second hot-air supplier is disposed adjacent to the inlet port in a state where the first door is closed.

4. The dryer as claimed in claim 2 , wherein the second drum is formed in a shape of a cylinder that is open toward the second opening, and
the plurality of vents are formed in an outer circumferential surface of the second drum.

5. The dryer as claimed in claim 4 , wherein the second drum case is formed as a shape of a cylinder, and
the inlet port and the exhaust port are formed in an outer circumferential surface of the second drum case.

6. The dryer as claimed in claim 5 , wherein the second drum case further includes an auxiliary inlet port that is open toward the first drying chamber.

7. The dryer as claimed in claim 6 , wherein the second drum further includes a plurality of auxiliary vents facing the auxiliary inlet port.

8. The dryer as claimed in claim 7 , wherein the inlet port, the auxiliary inlet port, and the exhaust port of the second drum case are formed in a grill structure, and
the plurality of vents and the plurality of auxiliary vents of the second drum are formed in a grill structure.

9. The dryer as claimed in claim 1 , wherein a driver is disposed at the first door, and a power transmission member is coupled to an opening portion of the second drum, the power transmission member transmitting a driving force of the driver to the second drum.

10. The dryer as claimed in claim 9 , wherein the power transmission member includes a third opening and a gear portion disposed along an outer circumference of the third opening, and
the driver includes a motor coupled to the first door and a drive gear coupled to the motor for rotation and engaged with the gear portion.

11. The dryer as claimed in claim 1 , further comprising an exhaust duct configured to discharge air in the first drum and the second drum to the outside of the body,
wherein an air suction port of the exhaust duct is disposed close to the exhaust port.

12. A dryer comprising a door configured to open or close an opening formed in one side of a body, a drying chamber rotatably disposed inside the body, and a hot-air supplier configured to supply hot air into the drying chamber, wherein
an auxiliary drying chamber is disposed inside the door, and
an auxiliary hot-air supplier is disposed adjacent to the auxiliary drying chamber to supply hot air into the auxiliary drying chamber,
the door comprises an inlet port through which hot air is introduced from the auxiliary hot-air supplier and an exhaust port through which the introduced hot air is discharged, the inlet port and the outlet port disposed between the auxiliary hot-air supplier and the auxiliary drying chamber,
the auxiliary drying chamber comprises a plurality of vents facing the inlet port and the exhaust port, and
the auxiliary hot-air supplier is disposed above the auxiliary drying chamber when the door is in a closed state.

13. The dryer as claimed in claim 12 , wherein the auxiliary drying chamber includes:
a fixed drum including a vent formed in a grill shape; and
a rotating drum rotatably disposed inside the fixed drum and including a vent formed in a grill shape in communication with the vent of the fixed drum.
