  • Patent number: 10526741
    Abstract: Disclosed herein is a washing machine including a balancer module which is actively driven in a balancer housing to damp load unbalance of the washing machine, a power supplying unit provided at an outside of a tub to supply electric power to the balancer module, and a wire configured to pass through a hollow portion of a rotating shaft of a flange shaft to electrically connect the balancer module and the power supplying unit. The washing machine comprises a slip ring disposed between the rotating balancer module and the fixed power supplying unit to prevent the wire from being twisted. An internal wire disposed in a rotating tub is covered by a waterproofing tube so as to prevent moisture from permeating the internal wire. The hollow portion of the rotating shaft of the flange shaft is sealed by a stopper member and a packing member so as to prevent the moisture from permeating. An external wire disposed at an outside of the tub may be neatly arranged by a guide bracket.
