Patent number: 8782837Abstract: Disclosed herein are a washing machine and a control method of the same. The control method includes detecting a position of a coupler coupled to a rotor of a drive motor in a first mode in which power from the drive motor is transmitted to a washing shaft and a spin-drying shaft and coupled to a rotation prevention unit of a water tub in a second mode in which the power from the drive motor is transmitted to the washing shaft, determining based on the position of the coupler whether the coupling of the coupler is abnormal, shaking the coupler at a present position or moving the coupler to a position before mode switching and shaking the coupler such that the coupler is moved to a position where the mode switching is to be performed.Type: GrantFiled: July 13, 2010Date of Patent: July 22, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Sung Mo Lee, Jae Young Choi, Jung Won Choi

Publication number: 20140182066Abstract: Provided is a washing machine. The washing machine includes an outer tub holding wash water, an inner tub rotatably provided in the outer tub and receiving laundry, a pulsator rotatably provided in the inner tub, a power transmission shaft rotating the pulsator, a buoyancy clutch that that moves up and down by buoyancy created by the wash water and transfers, when the buoyancy clutch is in a lower position, rotational force from the power transmission shaft to the inner tub to allow the pulsator and the inner tub to rotate integrally with each other, a circulation passage that is provided on an outer portion of the outer tub to allow the wash water drained out of the outer tub to be returned into the outer tub, a pump provided on the circulation passage and a drain guide unit that directs the wash water under the buoyancy clutch to a drain hole of the outer tub so that the buoyancy clutch moves downward.Type: ApplicationFiled: December 26, 2011Publication date: July 3, 2014Inventors: Jae Won Chang, Kyu Bum Lee, Young Jong Kim, Ae Kyung Chae

Publication number: 20140165661Abstract: A clutch positioning assembly for a washing machine appliance is provided. The assembly uses a cam that can be rotated so as to position the clutch between different positions that provide for engaging or disengaging a motor from a wash basket. A leaf spring, configured as a yoke in one exemplary embodiment, provides a force to urge the clutch into a position that e.g., disengages the wash basket from the motor during e.g., wash modes while also allowing the clutch to be moved into a position that engages the wash basket with the motor during spin modes. The clutch positioning assembly can be provided as a modular unit that is connected with the appliance during manufacturing.Type: ApplicationFiled: December 19, 2012Publication date: June 19, 2014Applicant: GENERAL ELECTRIC COMPANYInventors: Edward Simeon Chupka, Stephen Bernard Froelicher

Publication number: 20130333424Abstract: A small size pulsator-type automatic washing machine comprises a housing, a control panel seat mounted on the top of the housing, a pedestal mounted at the bottom of the housing, an outer tub and an inner tub mounted inside the housing. A direct driving motor and a bearing block are mounted at the bottom of the outer tub. The motor is mounted on the outer tub by fixing elements, and a motor shaft is coupled with a pulsator shaft inside the bearing block. A fastener strap fixes the motor and the bearing block together onto the outer tub of the washing machine, thus reducing occupied space of the washing machine while improving a variety of installation mechanism of conventional washing machine. An insulation unit is disposed in the joint between the motor shaft and the tub shaft, such that the two parts cannot be in direct contact.Type: ApplicationFiled: August 3, 2011Publication date: December 19, 2013Inventors: Peishi Lv, Sheng Xu, Jie Liu, Xiaojie Pi, Yuling Chen
