Abstract
Proposed is a clothing treatment apparatus (1). The apparatus (1) includes a moving hanger (100) configured to rotate about a hanger shaft (150) and a drive unit (MU) configured to rotate the hanger shaft (150). The drive unit (MU) includes an eccentric disk (260) having an eccentric portion (265) offset from a motor shaft (225) of a motor assembly (200). The drive unit (MU) further includes a plurality of link bars (LB) that connect the eccentric portion (265) and the hanger shaft (150) and are rotatable relative to each other. Link driving caused by the plurality of link bars (LB) prevents slippage during the driving process, thereby reducing loss of kinetic energy.
Claims30
A clothing treatment apparatus comprising:
- a casing having a treatment space formed therein;
- a moving hanger having a hanging portion disposed in the treatment space and configured to rotate about a hanger shaft;
- and
- a drive unit disposed in an operating space separate from the treatment space and configured to rotate the hanger shaft,
- wherein the drive unit comprises:
- a motor assembly configured to rotate a motor shaft;
- an eccentric disk configured to rotate about the motor shaft and having an eccentric portion offset from the motor shaft;
- and
- a plurality of link bars connecting the eccentric portion and the hanger shaft and connected rotatably to each other.
A clothing treatment apparatus comprising:
- a casing having a treatment space formed therein;
- a moving hanger having a hanging portion disposed in the treatment space and configured to rotate about a hanger shaft;
- and
- a drive unit disposed in an operating space separate from the treatment space and having a motor assembly that rotates the hanger shaft,
- wherein the drive unit comprises:
- a first driving point rotated by the motor assembly;
- a second driving point configured to revolve around the first driving point;
- a third driving point that maintains a predetermined linear distance from the second driving point and reciprocates along an arcuate path while maintaining a predetermined radius from the hanger shaft;
- and
- a fourth driving point formed on the hanger shaft and maintaining a predetermined linear distance from a motor shaft.
