Patent number: 8181297Abstract: A washing machine that performs a washing operation using eat high-temperature steam and a washing method of the same are disclosed. The washing method includes (a) driving a washing heater (40) mounted in a tub (56) to increase the interior temperature of the tub (56), and (b) driving a steam heater (74) mounted in a steam generation unit (70), such that high-temperature steam is generated and the high-temperature steam is supplied into the tub (56), to increase the interior temperature of the tub (56). A washing operation including the (a) step and the (b) step, which are combined either in the order of the (a) step->the (b) step->the (a) step or in the order of the (b) step->the (a) step->the (b) step, is carried out such that the interior temperature of the tub (56) is increased to a target temperature level.Type: GrantFiled: March 24, 2006Date of Patent: May 22, 2012Assignee: LG Electronics Inc.Inventor: Youn Dong Lee

Patent number: 8156590Abstract: A controlling method of a laundry machine is disclosed. The controlling method includes supplying wash water into a tub up to a predetermined water level, and controlling On/Off of a steam heater and a tub heater until a temperature inside the tub or a drum reaches a predetermined temperature at the predetermined water level. By using both the tub heater and steam heater in conjunction with a controlling of a water supply valve in order to acquire the predetermined water level and predetermined tub temperature, the controlling method is advantageous to improve energy efficiency of the laundry machine.Type: GrantFiled: May 30, 2008Date of Patent: April 17, 2012Assignee: LG Electronics Inc.Inventors: Seog Kyu Park, Youn Dong Lee
