Abstract:
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.
Abstract:
Disclosed are a laundry treatment machine and a method for controlling the same. In operation of a pump for circulating and draining water, since the load of water to be drained is sensed and whether an error occurs due to foreign substances is determined based on a current and a rotation speed of a motor included in the pump, unnecessary operation of the pump may not be performed, damage of the pump due to overload may be prevented, noise due to pump operation in overloaded state may be solved, and the efficiency of pump control may be improved.
Abstract:
A control method of a laundry treatment apparatus is disclosed. A control method of a laundry treatment apparatus comprising a tub(3) configured to provide a space for storing water, a drum (5) provided in the tub (3) for storing laundry, a stator (551) configured to generate a rotating field when current is supplied to the stator (551), a rotor (553) configured to be rotated by the rotating field generated by the stator (551), and a rotary shaft (555) extending through the tub (3) for connecting the rotor (553) to the drum (5), the control method includes: a laundry weight measurement step (S12) for rotating the drum (5) at a predetermined first number of rotations (S31) to measure a weight of the laundry stored (S16) in the drum (5); an unbalance measurement step (S14) for rotating the drum (5) at a predetermined second number of rotations (S31) to determine a magnitude of a dynamic unbalance of the drum (5);an acceleration step (S21) for accelerating the drum (5) to a target number of rotations (S31), which is greater than the first number of rotations (S31) and the second number of rotations (S31), when the magnitude of the dynamic unbalance measured at the unbalance measurement step (S14, S17) is less than a predetermined reference value (S15); a first interruption step (S51) for interrupting a rotation of the drum (5) when a variation per unit time of current supplied to the stator (551) during execution of the acceleration step (S21) is equal to or greater than a predetermined reference variation; a laundry weight remeasurement step (S24) for rotating the drum (5) at the first number of rotations (S31) to determine the weight of the laundry stored (S16) in the drum (5) and a second interruption step (S51) for interrupting the rotation of the drum (5) when a deviation between a laundry weight measured at the laundry weight remeasurement step (S12) and the laundry weight measured at the laundry weight measurement step (S12) is equal to or greater than a predetermined reference deviation (S25).
