  • Patent number: 9605367
    Abstract: A method of controlling a washing machine includes detecting a water level in a drum when a barrel cleaning is executed; supplying or draining water according to the detected water level such that a water level reaches a reference water level; soaking an interior of the drum in water; draining water after the interior of the drum is soaked in water; and detecting clothes contained in the drum by rotating the drum.

  • Patent number: 9528212
    Abstract: A washing machine and a control method thereof, capable of reducing noise by performing a zero-current control during the braking of a motor, and checking whether a vibration sensor is installed on a tub in a weight detection state in the beginning of a spin-drying. The zero-current control is performed by driving a current regulator with a command current set to “0 A”, so that the current flowing at the motor decreases and thus noise is reduced. In a washing machine having a vibration sensor fixedly attached to a tub, a fixation state of the vibration sensor with respect to the tub is checked in advance by use of measurement data of the vibration sensor at a weight detection stage in the beginning of the spin drying so that the frame touch caused by an erroneous detection of vibration or a failure of vibration detection may be prevented.

  • Patent number: 8721800
    Abstract: A method of controlling a washing machine, capable of detecting clothes contained in the washing machine by rotating a drum. The method includes supplying a predetermined amount of water when a barrel cleaning is executed, soaking an interior of a drum in water, draining water after the interior of the drum has been soaked in the water, and detecting clothes contained in the drum by rotating the drum. Whether to perform a barrel cleaning is determined according to the existence of the clothes in the drum, so that vibration and noise are prevented from being generated in the washing machine, and accident due to the movement of the washing machine is prevented.

  • Patent number: 8156592
    Abstract: Disclosed herein is a washing machine including a balancer, which increases the speed of a rotation tub stepwise in a period in which an excessive vibration of a water tub occurs to pass the excessive vibration period without the vibration, and a method of controlling the same. The method of controlling the washing machine includes increasing the speed of the rotation tub stepwise in the period in which the excessive vibration of the water tub occurs; measuring current of a motor to detect an amount of unbalance while the speed of the rotation tub is increased stepwise; and controlling the speed of the rotation tub based on the detected amount of unbalance.
