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: The present disclosure provides a control method capable of, by using a current value of a nozzle, determining whether a nozzle is separated from a vacuum cleaner and whether the nozzle is reconnected to the vacuum cleaner after separation. To this end, a vacuum cleaner may comprise a nozzle connectable to a suction unit for suctioning dusts. The nozzle may comprise a rotary cleaning unit for applying pressure to a cleaning target surface so as to separate a foreign substance therefrom, and a nozzle motor for driving the rotary cleaning unit. In order to drive the nozzle, a voltage having been controlled by a pulse width modulation (PWM) method is applied, and a measurement unit included in the vacuum cleaner may measure a current value of the nozzle, the current value depending on the applied voltage.

Abstract: The present disclosure provides a control method for automatically detecting what kind of nozzle is a nozzle mounted on a cleaner by using different starting current profiles. The cleaner may include a suction unit for suctioning dust, and various nozzles which are detachable from the suction unit. The nozzle may include a rotation cleaning unit which is accommodated in the nozzle to clean a surface to be cleaned, and a nozzle driving unit for driving the rotation cleaning unit. The nozzle may exhibit different starting current profiles depending on the number of rotations or reduction ratio of the nozzle driving unit, or whether an auxiliary control unit is included.

Abstract: A motor driving device controls a three-phase motor and a single-phase motor to operate in parallel. The motor driving device includes a dc terminal in which an upper and a lower DC-link capacitor are located. The motor driving device also includes a neutral terminal disposed between the upper and lower DC-link capacitors. The motor driving device includes an inverter that includes three pairs of upper switching elements and lower switching elements. Two pairs of upper switching elements and lower switching elements among three pairs are connected to an a-phase terminal and a b-phase terminal of the three-phase motor, respectively. The other pair of upper switching elements and lower switching elements among three pairs is connected to a first terminal of the single-phase motor. The neutral terminal is connected to a second terminal of the single-phase motor. A c-phase terminal of the three-phase motor is connected to the single-phase motor.

Abstract: A drum washing machine implements a control method, allowing a tub of the drum washing machine to be easily cleaned. The method includes supplying washing water during a first water supplying step to the interior of the tub while a drum rotatably supported in the tub rotates at a water-supplying RPM. A first wash step is executed following completion of the first water supplying step, and includes accelerating rotation of the drum from the water-supplying RPM to a first-wash RPM to that create a circulatory flow in which the washing water falls from the top of opposite ends of the tub while circulating along the inner circumferential surface of the tub due to the rotational power of the drum. A wash draining step is started during the first wash step, and includes turning on the drain pump and controlling the amount of the washing water in the tub.
