Clothes drying apparatus
A clothes drying apparatus in which lifters arranged on an inner peripheral surface of a rotating drum, while extending axially along the rotating drum, have an improved structure to achieve an enhancement in drying performance. The clothes drying apparatus includes a rotating drum to contain clothes to be dried, and a plurality of lifters arranged on the inner peripheral surface of the rotating drum. Each lifter has at least one first step surface, and a second step surface. The first and second step surfaces are arranged at different levels to form a stepped structure, so that they cause the clothes to be easily dropped after being raised by the lifter. A pair of first step surfaces are arranged at opposite end portions of the lifter, respectively, and the second step surface is arranged between the first step surfaces at a level lower than that of the first step surfaces.
1. A clothes drying apparatus, comprising:
a rotating drum with an approximately constant external diameter, to contain clothes to be dried; and
a plurality of lifters arranged on an inner peripheral surface of the rotating drum,
wherein an external surface of each lifter has at least one first step surface and a second step surface, the first and second step surfaces being arranged at different radial and circumferential levels to form an axially, radially, and circumferentially stepped structure causing the clothes to be easily released from the lifter after being raised by the lifter.
2. The clothes drying apparatus according to claim 1 , wherein the at least one first step surface comprises a pair of first step surfaces respectively arranged at opposite end portions of the lifter, and the second step surface is arranged between the first step surfaces at a level lower than that of the first step surfaces.
3. The clothes drying apparatus according to claim 1 , wherein the at least one first step surface comprises a pair of first step surfaces respectively arranged at opposite end portions of the lifter, and the second step surface is arranged between the first step surfaces at a level higher than that of the first step surfaces.
