摘要： A washing method according to the present invention comprises: a first rotation step for rotating an inner tub; a rotating direction detecting step for detecting the rotating direction of the inner tub; and a second rotation step for starting to rotate the inner tub in the opposite direction to the rotating direction of the inner tub when the rotation of the inner tub stops in the first rotation step. When the inner tub stops over a predetermined time and then restarts, the inner tub starts to rotate in the opposite direction to the rotating direction when the inner tub stops, thereby reducing the eccentricity of the inside of the inner tub, inhibiting collisions between the inner tub and an outer tub, reducing noise during collisions, and improving the rotation performance of the inner tub.

摘要： The present invention relates to a washing machine, and more specifically to a drum washing machine allowing a tub to be easily cleaned, and a method for cleaning the tub of the drum washing machine. To that end, the present invention, with respect to a method for controlling a washing machine comprising rinsing and spin-drying cycles, provides a method for controlling the washing machine comprising: a first water supplying step for supplying washing water to the interior of a tub while a drum is rotating at a water-supplying RPM; and first wash step, executed following the completion of the first water supply step, for accelerating the rotation of the drum from the water-supplying RPM to first-wash RPM so that a circulartory flow is created in which the washing water falls from the top of both ends of the tub while circulating along the inner circumferential surface of the tub due to the rotational power of the drum.

摘要： 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.
