  • Patent number: 8181297
    Abstract: 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.

  • Patent number: 8156590
    Abstract: 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.

  • Patent number: 8015644
    Abstract: A method for controlling a washing machine is disclosed. The method for controlling a washing machine having a steam generator includes a step of automatically discharging water of the steam generator outside of the steam generator during the operation of the washing machine. Therefore, according to the present invention, foreign substances may be efficiently prevented from precipitating in the steam generator.
