Abstract:
1. A washing machine, comprising: a laundry tub in which laundry is put; a water supply unit that supplies water to the laundry tub; an agitating unit that agitates the laundry in the laundry tub; an ion eluting portion for eluting metal ions and adding the eluted metal ions to water; a sensing portion for sensing imbalance at the time of rotation of the laundry tub; and a control unit configured to operate such that, on recognizing that the sensing portion has sensed imbalance during spin-drying rotation, if before the spin-drying rotation the ion eluting portion was controlled so as not to supply metal ions to the laundry tub, the control unit performs a first balance correction rinsing in which the control unit controls the water supply unit and the ion eluting portion to supply water containing no metal ions to the laundry tub and controls the agitating unit to perform agitation, and if before the spin-drying rotation the ion eluting portion was controlled so as to supply metal ions to the laundry tub, the control unit performs a second balance correction rinsing in which the control unit controls the water supply unit and the ion eluting portion to supply water containing metal ions to the laundry tub and controls the agitating unit to perform agitation.
