A washing machine includes a water tub arranged in a case and a damper installed between the case and the water tub for damping vibrations of the water tub. The damper includes a plunger having one end supported on the case; a rod having one end supported on the water tub and the other end movably inserted to the plunger; a housing arranged to wrap around some of the plunger and the rod and including a friction member arranged between the housing and the plunger to contact an outer circumferential surface of the plunger; and a switching device configured to be in a first state in which the rod is coupled to the housing and able to move within the plunger along with the housing and a second state in which the rod is decoupled from the housing and able to move solely within the plunger.

Provided is a balance assembly applied in a household appliance. The balance assembly includes: a balancing body having a chamber defined therein; a balancer movably located in the chamber; a first wireless charging assembly; and an energy storage device located outside the balancer and connected to the first wireless charging assembly. The first wireless charging assembly is configured to receive a charging energy wirelessly transmitted by the household appliance. The energy storage device, the first wireless charging assembly, and the balancing body are mounted within a cavity of the household appliance. The chamber has a first conductive structure provided on an inner wall thereof, and the first conductive structure is electrically connected to the energy storage device. The balancer includes a second conductive structure movably connected to the first conductive structure.

A laundry treating appliance is configured to treat laundry according to a cycle of operation. The laundry treating appliance comprises a chassis that defines an interior and has a front and rear with an access opening located in the front. A tub statically mounted to the chassis and defines a liquid chamber located within the interior and has at least one suspension opening. An exoskeleton is located within the liquid chamber and has a front support, a rear support, and stringers extending longitudinally to form a skeletal frame defining a frame interior. A rotatable drum is located within the frame interior. A suspension system is located within the interior and has at least one suspension component extending into the liquid chamber through the suspension opening and is operably coupled to the exoskeleton. A liquid dam retards liquid flow from the liquid chamber to the interior through the suspension opening.

A noise leakage preventing device for a clothes treating apparatus is provided. The device may include a base located at a lower portion of a cabinet and forming a bottom surface of the clothes treating apparatus, and a noise blocking rim attached along a periphery of a lower surface of the base and located between the base and the ground. The noise blocking rim may prevent noise generated from the clothes treating apparatus from being transferred or emitted out the base.

A laundry treating apparatus is provided. The laundry treating apparatus includes a cabinet, a drum accommodated in the cabinet, and a dynamic absorber provided to absorb oscillation of the cabinet. The dynamic absorber includes a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. Each of the first and second moving masses includes a single mass made of a metal material or a mass in which a plurality of thin metal plates are coupled to overlap each other, and the first moving mass has a mass greater than that of the second moving mass.
