The invention consists of a washing or washing/drying machine comprising a frame, an assembly constrained to said frame by constraint means that allow said assembly to oscillate relative to said frame, energy recovery means configured to transform kinetic energy in electrical energy, wherein said energy recovery means comprise a current generator configured to transform the oscillations of said assembly into an electrical current.

A fabric treating appliance for treating an article according to a cycle of operation includes a chassis defining an interior with a tub provided within the interior, the tub at least partially defining a liquid chamber. A drum is provided within the liquid chamber to at least partially define a treating chamber. The drum has a peripheral wall terminating in a front edge and a rear edge, with the front edge defining a front opening. An exoskeleton is provided within the liquid chamber coupling the drum to the chassis.

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.

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.

Provided is a control method for a laundry treating apparatus comprising: a drum in which laundry is stored; at least three balancers fixed to the drum and provided to be spaced from each other at the same angle with respect to the rotational center of the drum; front spaces provided in each balancer and positioned at the front of the drum; and rear spaces provided in each balancer and positioned at the rear of the drum, wherein the control method for the laundry treating apparatus comprises: a rear control step of supplying a liquid to at least one of the rear spaces so as to increase the weight of a quadrant (first target quadrant) positioned in the direction opposite to a quadrant, of a circumferential surface of the drum, to which a force causing unbalance is directed; and a front control step of supplying a liquid to at least one of the front spaces so as to increase the weight of a quadrant (second target quadrant) positioned in the direction opposite to the quadrant, of the circumferential surface of the drum, to which the force causing unbalance is directed.

A fabric treating appliance for treating an article according to a cycle of operation includes a chassis defining an interior with a tub disposed in the interior, the tub defining a liquid chamber. A drum is provided within the liquid chamber to define a treating chamber. An exoskeleton is disposed within the liquid chamber and houses the drum. A front frame mounts to the drum and forms at least a portion of the exoskeleton.

A washing apparatus and control method where the washing apparatus comprises a door configured to open and close the entrance; a tub inside a main body; a diaphragm configured to connect the entrance with the opening; and a drum rotatably provided inside the tub. The washing apparatus includes a door washing nozzle to inject water for a first time in a first section and then to inject the water for a second time in a second section when a washing mode of the diaphragm is entered. The washing mode of the diaphragm including the first section in which the drum in a stopped state is accelerated to arrive at a first target rotation speed less than a second target rotation speed and the second section in which the drum at the first target rotation speed is accelerated to arrive at the second target rotation speed.

The present invention refers to a balancing apparatus 100 for preventing vibrations and loud running in a drum 1 of a washing machine while operating. The balancing apparatus 100 according to the present invention preferably comprises of at least two half rings 2 and a plurality of propellers 3. The plurality of propellers are attached to the drum 1.The two half rings 2 are configured to cover the drum 1. The propellers 3 and the half rings 2 are magnetically polarized while electric current is passing through the propellers 3 and half rings 2. The drum 1 is balanced by forming similar polarity in poles of the half rings 2 and the poles of the propellers 3 facing each other.

A method for controlling a spin-drying operation of a washing apparatus includes a laundry dispersing step of dispersing the laundry inside a drum by accelerating the drum, a spin-drying step including detecting the eccentricity of the drum, and performing spin-drying by rotating the drum to a spin-drying RPM. The laundry dispersing step is re-executed when the eccentricity exceeds a reference eccentricity, and in the spin-drying step, a rotation time during which the drum rotates at the spin-drying RPM is adjusted according to a spin-drying degree. The spin-drying degree is measured after a point in time at which the eccentricity exceeds the reference eccentricity.

A laundry treating appliance having a tub, rotatable drum, at least one transmitter coil, at least one ring shaped housing on the drum perimeter and having an annular channel therein and at least one balancing unit disposed in the channel. The balancing unit has a receiver coil configured to receive wireless power from the transmitter coil and an actuator powered by the receiver coil, a sensing element to detect a position of the balancing unit in the housing, a balancing control unit configured to control the positioning of the balancing unit by driving the transmitter coil to send power to the receiver coil to operate the actuator on a friction force element to change the friction between the housing and the balancing unit.
