Publication number: 20090157231Abstract: The present invention relates to a washing machine and a method of controlling the same. The washing machine includes a home network switch unit for selectively inputting a home network mode or a standby power mode, a standby power unit for supplying or shutting off a main power according to an operating state, and a microcomputer for controlling the standby power unit according to a mode set by the home network switch unit. Thus, the home network mode or the standby power mode is selected, if appropriate, through manipulation of a switch. Accordingly, the washing machine can be driven even when it is connected to a home network. When the standby power mode is selected, applied main power is shut off. Accordingly, there is an advantage in that a washing machine with minimized power consumption can be provided.Type: ApplicationFiled: October 12, 2006Publication date: June 18, 2009Inventors: Gi Hyeong Do, Sang Il Hwang

Patent number: 6775923Abstract: A laundry drier control method is provided, by which drying time is dynamically controlled according to an amount and type of a drying object, using a calculated medium temperature to determine a medium temperature time. The method includes steps of initiating a drying procedure by actuating drivers, including a heater driver to increase an internal temperature of a laundry drier; determining a medium temperature time by measuring a time lapse from the drying procedure initiating step to a point where the internal temperature reaches a medium temperature between a drying initiation temperature and a maximum drying temperature; setting a drying time based on the determined medium temperature time; and performing the drying procedure for the set drying time. The drying time is set by multiplying the determined medium temperature time by a predetermined factor. The drying initiation temperature is the internal temperature at the time of initiating the drying procedure.Type: GrantFiled: November 21, 2003Date of Patent: August 17, 2004Assignee: LG Electronics Inc.Inventor: Gi Hyeong Do

Patent number: 5768731Abstract: A drying method for a drum-type washing machine includes the steps of: draining water from a load of laundry by maintaining a predetermined drying speed for a predetermined time in an initial drying step performed during a drying stroke of the drum-type washing machine; and sensing whether an eccentricity exists after expiration of a predetermined time and, if the eccentricity is not sensed, accelerating the drying speed to accomplish drying of the laundry. The drying method prevents a drum of the washing machine from generating a flushing noise in the case where an imbalance occurs during drying, and also prevents the laundry from becoming crumpled from sticking to the drum at the end of the drying procedure.Type: GrantFiled: July 16, 1996Date of Patent: June 23, 1998Assignee: LG Electronics Inc.Inventor: Gi Hyeong Do
