Patent number: 8490439Abstract: In a laundry washer, relatively short bursts of operation of a recirculation pump are coordinated with corresponding brief intervals of tub rotation during the initial fill periods. The aim is to thoroughly wet the clothes early in each wash/rinse phase to thus improve the wash/rinse effectiveness, while also avoiding excessive suds formation. Following the initial fill periods and during regular wash/rinse agitations, the recirculation system may also be employed to “recharge” the laundry load with detergent that has settled in the bottom of the tub. In a further aspect of the invention, some or all of the conventional intermediate spin extractions are omitted. In this manner, more water is carried over in the clothes from one wash/rinse cycle to the next. An intermediate spin of reduced speed (RPM) and duration as compared to typical normal intermediate spins may be employed between the wash phase and first rinse.Type: GrantFiled: April 18, 2012Date of Patent: July 23, 2013Assignee: Electrolux Home Products, Inc.Inventors: Chris H.

Patent number: 7874186Abstract: A washing machine has an abnormal vibration sensing apparatus. The abnormal vibration sensing apparatus includes a limiter having at least one opened side and connected to one of a vibrating body and a fixing body, a sensing rod having one end that is received in the limiter and separated from an inner wall of the limiter, and the other end that is connected to another of the vibrating body and the fixing body, and a contact sensing unit sensing whether the limiter and the sensing rod are in contact with each other so as to sense abnormal vibration of the vibrating body. According to this construction, it is possible to easily detect abnormal vibration in a plurality of directions without increasing the number of installing abnormal vibration sensing apparatuses.Type: GrantFiled: August 14, 2006Date of Patent: January 25, 2011Assignee: LG Electronics Inc.Inventors: Sang-Hoon Lee, Tea-Hee Lee

Patent number: 7827833Abstract: A drum type washing machine including a tub installed in a cabinet is disclosed. The drum type washing machine includes a drum performing washing, a motor rotating the drum, bearing housings having bearings to support a rotation shaft, a suspension connected to the bearing housings and the cabinet to mitigate vibration generated during rotation of the drum, a bracket installed to the bearing housings to form the rear side of the tub, and a gasket installed between the bracket and the tub to seal the tub and to prevent vibration from being transmitted from the bracket to the tub. Volumes of the tub and the drum can be easily increased without increasing the volume of the cabinet. Even when the volume of the washing machine is changed, only one of the tub and the bearing housings, which is not applicable to the drum type washing machine having the changed washing capacity, is selectively replaced. Thus parts can commonly used in various drum type washing machine having different volume.Type: GrantFiled: August 26, 2008Date of Patent: November 9, 2010Assignee: LG Electronics Inc.Inventors: Jae Won Chang, Hee Tae Lim, Si Moon Jeon, Kyeong Hwan Kim, Hyun Seok Seo

Patent number: 7810361Abstract: A washing apparatus includes an outer casing being disposed to contain liquid for washing, a cylindrical basket-like washing tub, a rotating mechanism, a sensor, a controller, and a plurality of slits. The cylindrical basket-like washing tub is disposed in the outer casing and disposed to contain clothing. The plurality of protruding portions are disposed on an inner surface of the cylindrical basket-like washing tub. The plurality of protruding portions protrude in a radial direction and extend along an axial direction. The rotating mechanism is disposed to rotate the cylindrical basket-like washing tub. The sensor is disposed to detect the level of the liquid in the outer casing. The controller is disposed to start rotating the cylindrical basket-like washing tub when the cylindrical basket-like washing tub is confirmed to be full of the liquid. The plurality of slits penetrate through the cylindrical basket-like washing tub.Type: GrantFiled: December 7, 2009Date of Patent: October 12, 2010Assignee: Happy Co., Ltd.Inventor: Hideo Hashimoto
