As a result, the clothes can be effectively dried while being suppressed from being unevenly dried. Furthermore, since the clothes can be dried while being tense, the number of wrinkles of the clothes can also be reduced.
  • drum 1 since clockwise and counterclockwise half-turns of drum 1 are repeated within a short period of time to make it possible to frequently blow up the clothes, the clothes can be dried while being suppressed from being unevenly dried and tangled.
