A washing machine includes a machine housing, a water accommodation tub disposed in the machine housing; a washing tub assembly disposed in the water accommodation tub and including a washing tub; and a balance ring mounted to an upper end of the washing tub and having a lower end fitted in the washing tub.

The present invention relates to a coupling system for fitting and attaching of a removable internal basket for a washing machine. The washing machine comprises a removable washing compartment configured to be mounted in the washing machine. The washing machine includes at least one convex protrusion or at least one concave groove across a portion of an inner side surface, and the removable washing compartment includes the other of at least one convex protrusion or at least one concave groove across a portion of an outer side surface. The balancing device includes a smooth surface portion across a portion of the inner side wall and the removable washing compartment includes a complimentary smooth surface portion across a portion of an outer side surface. When the removable washing compartment is mounted in the washing machine, the smooth surface portion on the inner side wall aligns with the smooth surface portion on the outer surface of the removable washing compartment and the at least one convex protrusion nests with the at least one concave groove such that the surface of the convex protrusion contacts the surface of the concave groove.

The present disclosure provides a support for household appliance and a household appliance. The support for household appliance comprises a hydraulic plate; a sheath, which is fixedly connected with the hydraulic plate; a regulating element, which is arranged in the sheath and is axially movable relative to the sheath; an accommodation chamber, which is formed by the hydraulic plate, the sheath and the regulating element; a hydraulic medium, which is arranged in the accommodation chamber and is compressed/expands depending on pressure changes to drive the regulating element to axially move in the sheath for leveling; a communicating device, which enables at least two supports for household appliance to communicate with each other to allow the hydraulic medium to flow between the supports for household appliance; a one-way valve structure is arranged in the communicating device for conducting the hydraulic medium to flow in one direction.

A washing machine is provided. The washing machine includes a dewatering tub having an impeller provided at a bottom thereof; three or more baffles arranged at equal intervals in a circumferential direction with respect to an inner circumferential surface of the dewatering tub, which are opened in the vicinity of the bottom and in which a water circulation opening is formed at the upper end; a water receiving ring unit fixed to an upper end of the dewatering tub and formed by stacking a plurality of annular water guiding grooves, which are connected to the upper end of the respective baffles via communication members; and a nozzle unit capable of individually injecting adjusting water into each of the water guiding grooves.

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.

A laundry treatment machine may include: a tub; a drum that is rotatably disposed in the tub; an actuator that provides power for rotating the drum; and a balancer device that is disposed at an end where the inlet hole of the drum is formed, and adjusts the center of gravity of the drum that is rotating. The balancer device may include: a main balancer that reduces vibration of the drum by moving in the opposite direction to eccentricity that is generated when the drum is rotated; a first sub-balancer of which an arrangement gap from the main balancer is adjusted in accordance with the degree of eccentricity of the drum; and a second sub-balancer of which an arrangement gap from the main balancer is adjusted in the opposite direction of the first sub-balancer with respect to the main balancer.

A washing machine appliance and methods of operation are provided. The washing machine appliance generally includes an apron and a sub-washer unit suspended within the apron by a plurality of dampers. A measurement device is mounted on the sub-washer unit to measure the movement of the sub-washer unit. The movement of each damper is calculated based on the relative position of the damper and the measurement device. By monitoring the movement of each damper, the amount of energy dissipated by each damper during operation may be calculated and the operation of the washing machine appliance may be adjusted when the amount of energy dissipated and/or power level exceeds a predetermined energy threshold.

Provided is a control method of a washing machine. The control method of the washing machine including: an unbalanced position detection for detecting an unbalanced position; a balancer selection for determining a baffle plate which requires for water injection; a first water injection for injecting adjusted water to the baffle plate farthest away from the unbalanced position by a water supply valve when water needs to be injected to at least two baffle plates; an unbalance amount detection for detecting a transition of the unbalance amount of the washing tub; and a water injection switching for switching the water injection from the water supply valve to a water supply valve when the unbalance amount detected by the unbalance amount detection has turned to an increase.

A washing machine appliance and a method of preventing and mitigating out-of-balance conditions during a spin cycle are provided. In one example aspect, liquid is flowed into the tub and articles within a basket rotatably mounted in a tub of the washing machine appliance are agitated for a first time period. The movement of the tub during the first time period is measured and a trend line is calculated based on the movement of the tub over the first time period. A time remaining is calculated based at least in part on the trend line. If the time remaining is less than a time remaining threshold, and if the determined time remaining is less than the time remaining threshold, the articles within the basket are agitated by an extended agitation time period in which the washing machine appliance attempts to more evenly distribute the articles prior to a spin cycle.

The present invention relates to a clothing treatment device comprising: a cabinet including a door through which laundry is put in and taken out; a tub provided inside the cabinet so as to store wash water; a drum rotatably provided inside the tub so as to accommodate the laundry; a balancer provided so as to be integrally rotatable with the drum, and supplying water to the inside thereof so as to maintain a dynamic balance of the drum; and a water supply part for supplying water to the balancer, wherein the balancer includes a draining part provided so as to drain water inside the balancer by a siphoning phenomenon when water of a certain water level or more is supplied to the inside of the balancer.
