Publication number: 20150020548Abstract: A laundry treatment apparatus includes a casing; an outer tub; a supporting member coupling the outer tub to the casing; and at least one horizontal vibration buffering device connecting the supporting member with a side surface of the casing. The horizontal vibration buffering device includes a casing connecting part coupled to the casing; a supporting member connecting part coupled to the supporting member, and a damper. The supporting member connecting part has a displacement relative the casing connecting part as the outer tub vibrates. The damper provides an attenuation force corresponding to the displacement of the supporting member connecting part relative the casing connecting part.Type: ApplicationFiled: July 22, 2014Publication date: January 22, 2015Inventors: Insik YU, Youngjun KIM, Youngjong KIM

Publication number: 20150013077Abstract: A washing machine with a balancer to counterbalance unbalanced load produced during rotation of a drum and a control method thereof. The washing machine with a balancer to counterbalance unbalanced load produced during rotation of a drum perform a ball distributing cycle of seating masses in a groove in the balancer before rotation of the drum possibly producing unbalance as in the spin-drying cycle begins to efficiently maintain balance of the drum, and a laundry untangling cycle of evenly distributing the laundry in the drum. Accordingly, vibration and noise may be reduced during the spin-drying cycle. In addition, in retrying the spin-drying, the ball distributing cycle is restricted based on the rate of rotation of the motor at the moment at which unbalance is sensed. Thereby, delay in cycle time in retrying the spin-drying cycle may be prevented.Type: ApplicationFiled: May 20, 2014Publication date: January 15, 2015Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Dong Ha JUNG, Jeong Hoon Kang, Min Sung Kim
