  • Patent number: 8168004
    Abstract: A washing machine that is capable of providing a stable washing mode even when a washing-related device is abnormal during a washing operation is disclosed. When a steam generation unit, which generates high-temperature steam into a drum, is abnormal, the operation of the steam generation unit is interrupted, and an operation for driving a washing heater mounted in a tub is performed, or an operation for driving a drying unit, which supplies high-temperature dry hot air into the drum, is performed. A steam substituting algorithm is provided when the steam generation unit is abnormal during the operation using the high-temperature steam. Consequently, the interruption of the washing operation due to the abnormal steam injection function is prevented, and therefore, the reliability of the product is improved while the inconvenience of use is minimized.

  • Publication number: 20100132127
    Abstract: A washing machine and a control method thereof that are capable of improving washing and rinsing efficiencies of large-volume laundry (for example, bedclothes). When large-volume laundry is washed and rinsed, a drum is accelerated to a predetermined velocity such that the laundry clings to the drum, and therefore, wash liquid (or water) comes into uniform contact with the entire surface of the laundry while the laundry widely spreads, is stopped such that the laundry is separated from the drum, and is rotated in alternating directions to change the position of the laundry such that a surface of the laundry contacting the wash liquid (or the water) is turned, and therefore, even contaminants inside the laundry are removed.

  • Patent number: 7721462
    Abstract: A semi-drying method of a washing machine, and a ventilating structure and a control apparatus for the same. In the semi-drying method, the dehydration and disentanglement of cloth are repeated plural times, and a washing tub is rotated at a designated dehydration speed for a time longer than that of the conventional dehydrating operation so as to minimize the jamming of the cloth into water pores of the washing tub, thereby increasing the dehydration degree of the cloth compared to the conventional dehydrating operation, removing offensive odors from the cloth, preventing damage to the cloth, allowing a user to select the duration of a semi-drying operation and to see the state of the semi-drying operation, and ventilating the washing tub during the semi-drying operation to improve the dehydration degree of the cloth.
