Abstract:
A device for driving a plurality of motors, including an inverter connected to a DC terminal; a multi-phase motor connected to the inverter; and a single-phase motor serially connected to the multi-phase motor, wherein a number of frequency of current input to the multi-phase motor when driving the single-phase motor and the multi-phase motor at the same speed is smaller than the number of frequency of current input to the multi-phase motor when driving the single-phase motor and the multi-phase motor at different speeds. Accordingly, a plurality of motors can be simultaneously driven at different speeds, by using a single inverter.
Abstract:
The present invention relates to a method for controlling a laundry treating apparatus (100) including a first course (S30) for rotating washing water and laundry which are loaded in a drum (130), in a state where a drainage pump (150) is off and a first spinning course for eliminating water elements from the laundry loaded in the drum (130) after the first course (S30), accelerating the drum (130), wherein the first spinning course comprises a preparing course for rotating the drum (130), in a state where the drainage pump (150) is off and a drainage course (S31) for draining the washing water inside the drum (130), in a state where the drainage pump (150) is on.
Abstract:
Washing machine control method including an outer tub and an inner tub containing clothes rotatably disposed therein. The method includes detecting an amount of dry clothes, supplying water between the outer and inner tub such that the clothes are not wetted, discharging water from the outer tub to a circulation channel and introducing water into the inner tub through the circulation channel to wet the clothes, discharging unabsorbed water collected in the outer tub to the circulation channel such that a water level in the outer tub becomes zero while detecting a flow rate of water, and determining an amount of circulation water discharged to the circulation channel based on the flow rate detected until a water level in the outer tub becomes zero and determining properties of the clothes based on the amount of circulation water and a predetermined anticipated amount of circulation water corresponding to the amount of dry clothes detected.
Abstract:
A control method for a laundry treatment apparatus, where the laundry treatment apparatus includes a first reservoir for holding water and defining a first opening for introduction of laundry, a second reservoir placed inside the first reservoir, the second reservoir being rotatable about a rotation axis perpendicular to a bottom surface of the first reservoir and defining a second opening that is positioned under the first opening, a through-hole that is defined in the second reservoir, a spray unit for spraying water to an inside of the second reservoir, and a drain unit for draining water inside the first reservoir, includes rotating the second reservoir to thereby apply force on laundry received in the second reservoir, spraying water to the inside of the second reservoir via the spray unit, and discharging the sprayed water in the second reservoir to an outside of the first reservoir via the drain unit.
Abstract:
The present invention relates to a control method of washing machine including an external tub to receive washing water, an internal tub rotatably disposed in the external tub to receive foams, and a motor to rotate the internal tub. The control method of the washing machine includes a water supply step of supplying washing water to the external tub and a change step of sequentially increasing or reducing target speed of the motor.
Abstract:
A washing machine and a control method thereof including supplying wash water into a space defined between an outer tub and an inner tub without wetting the laundry placed in the inner tub, operating the circulation pump to supply water from the outer tub to the inner tub, measuring a current value supplied to a circulation pump, stopping the operation of the circulation pump based on the measured current value, and calculating the amount of wash water supplied by the circulation pump based on the number of rotations of the circulation pump integrated until that time.
Abstract:
The present invention relates to an operation method of a washing machine for controlling the rotation of a pulsator to enhance cleaning performance, there is provided a method of operating a washing machine having a pulsator rotatably provided in a tub, and the method may include a first cleaning mode having a first process of rotating the pulsator in one direction at a first angle and then rotating it in the other direction at a second angle around the rotation shaft; and a second process of rotating the pulsator in the one direction at a third angle and then rotating it in the other direction at a fourth angle around the rotation shaft, wherein the first angle is greater than the third angle, and the second angle is greater than the fourth angle, and the second angle is greater than the third angle.
