  • the present invention relates to a washing machine having a dehydration function.
  • Washing machines installed in general households or laundromats are equipped with a washing and dehydration function and a washing, dehydration and drying function.
  • a washing machine having a dehydration function generates vibrations and noises due to a shifting of laundry in a rotating drum. Also, if the shifting of the laundry is relatively large, the eccentricity of the rotating drum at the time of rotation becomes large. A large torque is required for the rotation, so a dehydration operation cannot be started. In order to solve this problem, a user needs to stop the operation of the washing machine and manually eliminate the shifting of the laundry.
  • a solution has been provided as follows: a difference in the detected vibration amount is calculated by an acceleration sensor provided to the front portion and the rear portion of the rotating drum, thereby detecting an unbalanced state in which the laundry is biased toward the front portion of the rotating drum (see Patent Literature 2).

  • the direction of the axis of the washing tub extends in a substantially vertical direction
  • the partition portion has a bottom surface for storage that protrudes from an inner wall surface of the balancer and is capable of suppressing downward falling of the adjusted water
