Abstract

A clothing treatment apparatus includes a frame, a hanger body provided to hang clothing or a hanger, and a vibration module generating vibration, and configured to move the hanger body with respect to the frame. The vibration module includes a first eccentric portion rotating about a predetermined first rotation axis, a second eccentric portion rotating about a predetermined second rotation axis that is spaced apart from and parallel to the first rotation axis, and a vibrating body fixed to a predetermined central axis that is fixed to the frame and disposed between the first rotation axis and the second rotation axis. The first eccentric portion and the second eccentric portion rotate in the same direction to rotate the vibrating body about the central axis.

First claim

The invention claimed is:

1. A clothing treatment apparatus comprising:
a frame;
a hanger body provided to hang clothing or a hanger; and
a vibration module generating vibration, and configured to move the hanger body with respect to the frame,
wherein the vibration module comprises:
a first eccentric portion rotating about a predetermined first rotation axis;
a second eccentric portion rotating about a predetermined second rotation axis that is spaced apart from and parallel to the first rotation axis; and
a vibrating body fixed to a predetermined central axis that is fixed to the frame and disposed between the first rotation axis and the second rotation axis, and

wherein the first eccentric portion and the second eccentric portion rotate in the same direction to rotate the vibrating body about the central axis.

2. The clothing treatment apparatus according to claim 1 , wherein a direction in which the first eccentric portion is located with respect to the first rotation axis is opposite to a direction in which the second eccentric portion is located with respect to the second rotation axis.

3. The clothing treatment apparatus according to claim 1 , wherein the vibration module further comprises a hanger driving unit that connects the hanger body and the vibration body,
wherein the hanger body comprises a hanger driven unit connected to the hanger driving unit and configured to vibrate in a predetermined vibration direction (+X, −X), and
wherein either the hanger driving unit or the hanger driven unit has a slit that extends in a direction (+Y, −Y) intersecting the vibration direction (+X, −X), and the other has a protruding portion that protrudes in parallel with the central axis and is inserted into the slit.

4. The clothing treatment apparatus according to claim 1 , wherein the first rotation axis and the second rotation axis are spaced apart from each other in opposite directions based on the central axis.

5. The clothing treatment apparatus according to claim 4 , wherein (i) a distance between the first rotation axis and the central axis and (ii) a distance between the second rotation axis and the central axis are provided to be same as each other.

6. The clothing treatment apparatus according to claim 5 , wherein (i) an angular speed of the first eccentric portion about the first rotation axis and (ii) an angular speed of the second eccentric portion about the second rotation axis are preset to be same as each other.

7. The clothing treatment apparatus according to claim 1 , wherein the first eccentric portion and the second eccentric portion are provided in the same shape, and
the weight of the first eccentric portion and the weight of the second eccentric portion are the same.

8. The clothing treatment apparatus according to claim 1 , further comprising:
a motor disposed at the vibrating body and disposed between the first rotation axis and the second rotation axis; and
a transmitting portion disposed at the vibrating body and transmitting the torque of the motor to the first eccentric portion and the second eccentric portion.

9. The clothing treatment apparatus according to claim 8 , wherein the transmission unit includes:
a center transmission unit which integrally rotates with a motor shaft of the motor;
a first transmission unit which includes a gear or a belt for transmitting a rotational force of the center transmission unit to the first eccentric portion; and
a second transmission unit which includes a gear or a belt for transmitting the rotational force of the center transmission unit to the second eccentric portion.

10. The clothing treatment apparatus according to claim 9 , wherein the first eccentric portion includes:
a first rotating portion which comes into contact with the first transmission unit and rotates about the first rotation axis; and
a first weight member which is fixed to the first rotating portion, wherein the second eccentric portion includes:
a second rotating portion which comes into contact with the second transmission unit and rotates about the second rotation axis; and
a second weight member which is fixed to the second rotating portion, and
wherein a direction in which the first weight member is located with respect to the first rotation axis at an arbitrary time point is opposite to a direction in which the second weight member is located with respect to the second rotation axis.

11. The clothing treatment apparatus according to claim 10 , wherein the first weight member and the second weight member are provided at a height overlapping each other.

12. The clothing treatment apparatus according to claim 1 , further comprising:
a supporting member fixed to the frame and rotatably supporting the vibration body with respect to the central axis; and
an elastic member having one end fixed to the vibration body and the other end fixed to the supporting member.

13. The clothing treatment apparatus according to claim 12 , wherein the elastic member comprises:
a first elastic member fixed between the upper side of the vibration body and the supporting member; and
a second elastic member fixed between the lower side of the vibration body and the supporting member.

14. The clothing treatment apparatus according to claim 13 , wherein the first elastic member and the second elastic member are provided with a torsion spring.

15. The clothing treatment apparatus according to claim 12 , wherein when the first elastic member rotates the vibration body in one of clockwise direction and counterclockwise direction, the second elastic member rotates the vibration body in a direction same of the first elastic member.

16. The clothing treatment apparatus according to claim 1 , wherein the vibration module further comprises a hanger driving unit that connects the hanger body and the vibration body in front (+Y) of the central axis.

17. The clothing treatment apparatus according to claim 16 , wherein, when the vibration body rotates about the central axis, the hanger driving unit rotates together with the vibration body.

18. A clothing treatment apparatus comprising:
a frame;
a hanger module including a hanger body which is disposed to be movable to the frame and is provided to hang clothing or a hanger; and
a vibration module which generates vibrations,
wherein the vibration module includes:
a vibrating body which is rotatably provided about a predetermined central axis fixed to the frame;
a first eccentric portion which is supported by the vibrating body and rotates about a predetermined first rotation axis spaced apart from the central axis;
a second eccentric portion which is supported by the vibrating body and rotates about a predetermined second rotation axis which is spaced apart from the central axis and is the same as or parallel to the first rotation axis; and
a hanger driving unit which is fixed to the vibrating body and is connected to the hanger body at a position spaced apart from the central axis,

wherein, when the first eccentric portion rotates the vibrating body in one of clockwise (D 11 ) and counterclockwise (D 12 ) direction (D 1 ) with respect to the central axis, the second eccentric portion rotates the vibrating body in the one direction (D 1 ) with respect to the central axis, and
wherein, when the first eccentric portion is positioned with respect to the first rotation axis in one direction (D 2 ) of a centrifugal direction (Dr 1 ) and a mesial direction (Dr 2 ) based on the central axis, the second eccentric portion is positioned with respect to the second rotation
