    Abstract: A washing apparatus relies on oscillation motion that are controlled by a computer and a singular or a plural number of vibrators to cause a spring-supported sealed container containing the washing object and its surrounding liquid to oscillate in resonance motion. The purpose of fast and efficient cleaning is achieved through relative movements, frictions and air bubbles among the washing objects, container wall and liquid together at the result of this resonant motion. A plural number of motion sensors provide input signals to the computer to calculate and monitor the system resonant frequency variation and drifting of the washing apparatus and to control the vibrators' drive frequency in real-time to maintain this resonant motion for washing apparatus throughout the washing cycle under different washed object types and load conditions.

  • 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: 20110314616
    Abstract: A method of operating a washing machine to detect unbalanced loads has been developed. The method includes operating a motor to rotate a tub holding a load at a first rotational rate that is below a threshold rotational rate, identifying a mass of the load, operating the motor to rotate the tub at a second rotational rate that is above the threshold rotational rate, identifying a power applied to the motor to continue rotation of the tub at the second rotational rate, obtaining an out of balance mass value from a memory with reference to the power applied to the motor, second rotational rate, and identified mass, identifying a maximum rate for the tub with reference to the out of balance mass value, and operating the motor to rotate the tub at a rate that is less than or equal to the maximum rate.
