A washing machine having a balancer housing capable of transmitting electric power from an external power source to a balancing module. The washing machine includes a rotary drum, and a balancer to counterbalance an unbalanced load generated in the rotary drum. The balancer includes a balancer housing mounted to the rotary drum, and a balancing module having a moving unit to move inside the balancer housing. The balancer housing includes an electrode provided at an inner surface of the balancer housing in a circumferential direction thereof in order to transmit electric power to the moving unit of the balancing module, an electric wire electrically connected to the electrode in order to apply electric power from an external power source to the electrode, and a connector provided at an outer surface of the balancer housing in order to electrically connect the electric wire and the electrode.

A balance ring for an appliance, such as e.g., a washing machine, is provided. The balance ring can reduce or eliminate features such as sink marks that might otherwise impede the movement of counterweights in the balance ring. The counterweights are used to stabilize a rotating element of the appliance.

A shock absorber spring is provided. The shock absorber spring is constructed as a single unit having an internal shaft which passes back through the coils of the spring. A first end of the internal shaft is secured to a stationary object (such as the top of a washing machine) while the second end of the internal shaft is surrounded by the spring and hangs down in a generally vertical orientation. The second end of the shock absorber spring is then secured or hung to the heavy, moving object and allows the heavy, moving object to move in a restricted, desired manner by dampening and absorbing the vibrations of the object. The shock absorber spring has an internal travel limiter which may make contact with an extended bump located at the bottom of the internal shaft wherein the internal travel limiter contacts the extended bump and prevents the shock absorber spring from over compressing.
