摘要: A method for operating a washing machine appliance includes flowing a volume of liquid into a tub, agitating articles within the tub for a first period, the tub containing the volume of liquid, and measuring movement of the tub during agitation of the articles within the tub, the tub containing the volume of liquid. The movement is measured as one or more displacement amplitudes using an accelerometer and a gyroscope. The method further includes agitating articles within the tub for a second period when the final measured movement is greater than an out-of-balance movement threshold, the tub containing the volume of liquid. The method further includes draining liquid from the tub when the final measured movement is less than the out-of-balance movement threshold, and spinning a basket after draining liquid from the tub.

摘要: Disclosed herein are a washing machine with a balancer to counterbalance unbalanced load produced during rotation of a drum and a control method thereof. The washing machine having a balancer to counterbalance unbalanced load produced during rotation of the drum seats a mass in a groove in the balancer before rotation of the drum possibly producing unbalance as in the spin-drying cycle begins, thereby efficiently maintaining balance of the drum. Accordingly, vibration in the drum may be reduced and product liability incident due to touch of the frame may be prevented.

摘要: A method for operating a washing machine appliance includes flowing a volume of liquid into a tub, and agitating articles within the tub for a first period and using a first agitation profile, the tub containing the volume of liquid. The method further includes measuring movement of the tub during agitation of the articles within the tub, wherein the step of measuring movement occurs after agitating articles within the tub for the first period and for an intermediate measurement period and using an intermediate agitation profile, and wherein the intermediate agitation profile is different from the first agitation profile. The method further includes agitating articles within the tub for a second period when the final measured movement is greater than an out-of-balance movement threshold. The method further includes draining liquid from the tub when the final measured movement is less than the out-of-balance movement threshold.

摘要: A method for operating a washing machine appliance includes flowing a volume of liquid into the tub, and agitating articles within the tub for a first period, the tub containing the volume of liquid. The method further includes draining a first portion of the volume of liquid from the tub, the first portion less than the volume flowed into the tub, wherein a sum of the first portion and a second portion of the volume of liquid remaining in the tub equals the volume. The method further includes measuring movement of the tub during agitation of the articles within the tub after draining the first portion of the volume of liquid from the tub, wherein the step of measuring movement occurs after agitating articles within the tub for the first period and for an intermediate measurement period.

摘要: An apparatus and method for reducing displacement of a washing machine having a drum rotatable about an axis of rotation is disclosed. The washing machine comprises a chassis and a motor for rotation a drum. The drum is suspended from the chassis by a suspension. The suspension can comprise springs having six natural frequencies that can resonate at a rotational speed of the drum driven by the motor. The suspension system can be tuned such that resonant frequencies can be varied based upon rotational speed of the drum.

摘要: A laundry treatment machine includes a drum, a motor to rotate the drum, and a driving unit to drive the motor, wherein the driving unit includes an inverter to convert direct current (DC) voltage into alternating current (AC) voltage and to output the AC voltage to the motor and an inverter controller to control the inverter to supply an alignment current to the motor so as to align the motor during a starting operation of the motor and to supply a torque current for rotating the motor to the motor together with the alignment current after the motor is aligned. Such a laundry treatment apparatus prevents a reverse rotation phenomenon of the drum due to load.

摘要: A method of operating a laundry treating appliance includes accelerating rotation of the drum, determining a torque of the motor, an acceleration of the drum, a speed of the drum, and/or an angular position of the drum, repeatedly estimating the inertia of a laundry load using a parameter estimator based on the torque, acceleration, speed, and/or angular position of the drum, and monitoring a rate of change of the inertia from the repeated estimations of inertia. If the rate of change equals a threshold, the acceleration is adjusted.

摘要: A washing machine with a balancer to counterbalance unbalanced load produced during rotation of a drum and a control method thereof. The washing machine with a balancer to counterbalance unbalanced load produced during rotation of a drum perform a ball distributing cycle of seating masses in a groove in the balancer before rotation of the drum possibly producing unbalance as in the spin-drying cycle begins to efficiently maintain balance of the drum, and a laundry untangling cycle of evenly distributing the laundry in the drum. Accordingly, vibration and noise may be reduced during the spin-drying cycle. In addition, in retrying the spin-drying, the ball distributing cycle is restricted based on the rate of rotation of the motor at the moment at which unbalance is sensed. Thereby, delay in cycle time in retrying the spin-drying cycle may be prevented.
