Abstract:
A method of controlling a motor-driven washing machine. The method includes increasing a speed of a motor from zero to a first predetermined speed W1. Reducing the motor speed from W1 to a second predetermined speed W2 and measuring the deceleration period. Increasing the motor speed from W2 to a third predetermined speed W3 and braking the motor according to a slow brake logic if a first interruption of the motor is ordered during the step of increasing the motor speed from W2 to W3. Increasing the motor speed from W3 to a fourth predetermined speed W4 and selecting one of plurality of rapid-brake logics on the basis of the measured deceleration period and braking the motor according to the selected rapid-brake logic if a second interruption of the motor is ordered during the step of increasing the motor speed from W3 to W4.

Disclosed is a control method of a laundry machine. The control method of a laundry machine included with a balancer for performing a balancing step at least three times in a spinning cycle, the control method comprising a step configured to balance the drum at least one time before and while a rotation speed of the drum passes a transient region, a step configured to determine an irregular vibration region of the laundry machine and a balancing step implemented at least one time before a rotation speed of a drum enters the irregular vibration region, while the rotation speed is passing the irregular vibration region and after the rotation speed passes the irregular vibration region.
Abstract:
The patent application discloses a control method of a laundry machine provided with a balancer. The method includes a balancing step of at least one time for rotating a drum (30) at a constant speed for a predetermined time by decelerating the drum (30) if the drum (30) is accelerated at a predetermined RPM or more. The balancing step is performed after a rotation speed of the drum (30) passes through a transient region of the laundry machine (100).
Abstract:
A washing machine is provided. The washing machine controls a dehydration rotation speed by detecting a phase difference between a ball balancer and the laundry. Further, the washing machine controls a dehydration rotation speed at a dehydration segment based on a dehydration rotation speed of a driving device. Thereby, the washing machine minimizes energy using in a dehydration process by accelerating the dehydration rotation speed at a point at which a phase difference between the ball balancer and the laundry is a maximum. Further, by accelerating the dehydration rotation speed at a point at which the phase difference is a maximum, a vibration of the washing machine is remarkably reduced.
Abstract:
A controlling method of a washing machine is disclosed. A controlling method of a washing machine includes spinning to rotate a drum at a first speed to dehydrate the laundry, water draining to drain water from the drum, water supplying to supply water to a tub, while rotating the drum at a second speed for the laundry to be closely in contact with an inner circumferential surface of the drum, and penetration rinsing while rotating the drum at the second speed or at a third speed to rinse the laundry. According to the controlling method, a time taken to perform a rinsing cycle may be reduced. Furthermore, rinsing efficiency may be improved together with the reduced time of the rinsing cycle.
Abstract:
A method for washing laundry and a washing machine, in which balancing of the laundry load is effectively carried out. The method for washing includes supplying wash water mixed with a detergent, spinning or rinsing the laundry by rotating the washing machine drum in which the laundry is located, thereby causing the laundry to be repeatedly lifted within and then fall towards the bottom of the drum. The method further involves balancing the laundry by repeatedly accelerating and decelerating the drum. The wash water is then drained.
Abstract:
A washing machine is disclosed. The washing machine has a function of rotating a drum (130) at a low speed when a user pulls out laundry, enabling the user to easily search through the laundry. The washing machine includes a cabinet (100) defining an exterior appearance of the washing machine, a tub (120) mounted in the cabinet (100) and configured to receive wash water therein, a drum (130) rotatably mounted in the tub (120) and configured to receive laundry therein, an independent drive input unit (200) to send a drum rotating signal, so as to allow a user to operate the drum (130) independently of a washing process, and a control unit to control rotation of the drum (130) in response to a signal received from the independent drive input unit (200).
Abstract:
A control method of a laundry machine is disclosed. The control method of a laundry machine includes a vibration sensing step configured to sense vibration of a drum (320), transient region passing identifying step configured to identify transient region passing of the drum (320) in case the vibration of the drum (320) sensed in the vibration sensing step is a preset vibration value or more and a drum rotation speed controlling step configured to control the rotation speed of the drum (320) based on whether the rotation speed of the drum (320) passes a transient region.
Abstract:
A control method of a laundry machine is disclosed. The control method of laundry machine having a drum, a front balancer provided with a front portion of the drum and a rear balancer provided with a rear portion of the drum includes accelerating the drum and rotating the drum at a constant speed of a predetermined rotation speed for a predetermined time period, the predetermined rotation speed allowing that perpendicular displacement at the front portion of the drum is different from that at the rear portion of the drum.
Abstract:
A control method of a laundry machine is disclosed. The control method of a laundry machine comprising a balancer includes an unbalance sensing step, wherein the unbalance sensing step recognizes an unbalancemaximum value and an unbalanceminimum value of an unbalance wave and the unbalance sensing step determines an average value of the two unbalance maximumvalue and unbalanceminimum value to be of the unbalance generated in a drum provided in the laundry machine.
