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.

A dynamic balancing assembly for a laundry apparatus includes a control unit, one or more counterweight devices, and one or more clocksprings. The one or more counterweight devices are configured to be orbited about a primary rotation axis of the laundry apparatus to counteract a load imbalance in a drum of the laundry apparatus. The one or more clocksprings communicatively couple each of the one or more counterweight devices to the control unit.

Apparatus and methods of reducing a likelihood of contact between a rotating laundry-container, such as a basket or drum, located within a tub of a laundry treating appliance where the method includes rotating the drum during a measurement period, determining a torque, speed, acceleration, and position of the drum, using a parameter estimator to estimate the position of a mass relative to an imbalance of laundry and accelerating the rotation of the drum when the mass is determined to be angularly spaced from the relative position of the imbalance of laundry.

A dynamic balancer device for mounting to and balancing a rotatable drum in a laundry treating appliance comprises an enclosed non-metal annular housing having a radial circumferential wall, an annular metal race within the non-metal annular housing disposed against the radial circumferential wall, and a mass disposed in the annular race and movable therein.

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 includes a treating chamber provided for receiving laundry for treatment, a controller having a memory in which is stored a set of executable instructions including a set of cycles of operations. The laundry treating appliance also includes a user interface operably coupled with the controller and having a touchscreen configured to provide an input and output function for the controller.

The present invention relates to a laundry treating apparatus. The laundry treating apparatus according to an embodiment of the present invention includes a control unit which controls the tub to rotate at a first speed in a case of a blanket dehydration mode, to rotate at a second speed lower than the first speed so that the plurality of balls are dispersed when amount of eccentricity in the first speed rotation is equal to or greater than a first reference value, and to rotate at a third speed higher than the first speed when the amount of eccentricity in the first speed rotation is less than the first reference value. Accordingly, in a blanket dehydration mode, it is possible to stably perform dehydration by preventing the plurality of balls from operating unbalanced.

A washing machine includes: a tub; a transmission coil provided in the tub and transmitting power wirelessly; an ammeter measuring an input current value of the transmission coil; a cylindrical drum disposed inside the tub and configured to rotate; a balancer for reducing unbalance during rotation of the drum; and a controller controlling the ammeter and the balancer. The balancer includes: a reception coil provided in the drum and configured to generate power from magnetic field formed by the transmission coil; drive modules driven by power of the reception coil and provided in the drum; and at least one balancing weight that moves along a circumference of the drum by a driving force of each drive module, and changes a center of gravity of the drum. The controller determines a position of the balancing weights based on the input current value when the drum rotates.

An apparatus for treating laundry includes a tub, a drum, a motor configured to rotate the drum, a rotation shaft coupled to the motor, a first body including a first body hub located at a rotational center of the drum and fixed to the drum and a first body arm extended from the first body hub toward an edge of the drum, a second body including a second body hub located in the tub and fixed to the rotation shaft and a second body arm extended from the second body hub toward the first body arm, a connecting part connecting the first body to the second body and defining a space between the first body and the second body, and a reinforcement rib extended from the connecting part along the first body arm to connect the connecting part to the first body arm or the second body arm.

A dynamic balancer device for mounting to and balancing a rotatable drum in a laundry treating appliance comprises an enclosed non-metal annular housing having a radial circumferential wall, an annular metal race within the non-metal annular housing disposed against the radial circumferential wall, and a mass disposed in the annular race and movable therein.
