  • a washing machine is an apparatus which washes laundry by rotating a cylindrical drum in which the laundry and wash water are contained. Washing machines are divided into a drum washing machine which washes laundry by tumbling the laundry through rotation of a drum and a pulsator washing machine which washes laundry by water current generated by rotation of a pulsator.
  • a washing machine includes a tub to contain wash water, a drum rotatably installed within the tub and provided with spin-drying holes formed on the circumferential surface thereof for spin-drying, and a drive device to drive the drum.
