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.

A washing machine appliance, including one or more methods of operation, is provided herein. A method of operation may include rotating articles within a tub at a tumble speed for a first period and rotating articles within the tub at a pre-plaster speed for a second period following the first period. The pre-plaster speed may be greater than the tumble speed. The method may also include measuring movement of the tub during the second period. The method may further include determining whether a set condition is met based on the measured movement, and rotating articles within the tub at a plaster speed in response to determining the set condition is met based on the measured movement.

Disclosed is a method for controlling a spin-drying cycle of a laundry treatment machine. The method includes performing a plurality of spin-drying operations by rotating a drum above an adjusted rotational speed range configured to adjust disposition of balls within a ball balancer so as to correspond to a changed amount of eccentricity, and adjusting the disposition of the balls within the ball balancer by rotating the drum within the adjusted rotational speed range, between the respective spin-drying operations.

The laundry treating appliance can comprise a wash basket defining a washing chamber, having a clothes mover in the treating chamber to agitate the clothes during a cycle of operation for cleaning. The method can comprise supplying a wash liquid to the treating chamber and rotating the clothes mover within the treating chamber with an electric motor operating at a high duty cycle wash phase and a low duty cycle wash phase.

Provided are a washing method and washing machine. In the washing method, an eco-rinsing process where a drum rotates in a state where at least a portion of laundry is pressed against the inner wall of the drum and wash water is sprayed into the drum is performed. A spinning process where the spraying of the wash water is stopped and the wash water is removed from the laundry by accelerating the drum is performed. Here, at least a portion of the laundry remains pressed against the wall of the drum in the eco-rinsing process and the spinning process.

A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A motor assembly selectively rotates the wash basket, a drain pump assembly selectively drains wash fluid from the wash tub, and a camera assembly is used to monitor an out-of-balance value to minimize out-of-balance issues. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain one or more images of the wash chamber, analyze the one or more images using a machine learning image recognition process to determine the out-of-balance value of the load of clothes in the wash basket, and perform a cloth redistribution process based at least in part on determining that the out-of-balance value is greater than a predetermined out-of-balance threshold.

Washing machine appliances and suspension assemblies for suspending tubs in washing machine appliances are provided. A suspension assembly includes a frame, a mount seated on the frame, and a rod coupled to the mount. The rod is rotatable about a pivot point. The suspension assembly further includes a sensor assembly operable to monitor rotation of the rod. The sensor assembly includes a sensor and a reference surface. One of the sensor or the reference surface is coupled to the rod and rotatable with the rod relative to the other of the sensor or the reference surface. The sensor is operable to measure reference distances from the reference surface.

A control unit comprises a calculation unit, a determination unit, and a motor rotation control unit. The calculation unit calculates the rate of change in water level, which indicates the amount of change in water level per a predetermined period of time, on the basis of the result of sensing by a water level sensor in connection with a water supply stroke. The determination unit determines whether laundry having a waterproof property is contained in a drum or not on the basis of the rate of change in water level during the water supply stroke calculated by the calculation unit. When it is determined that laundry having a waterproof property is contained in the drum, the motor rotation control unit controls the operation of a driving motor such that the drum is rotated at a predetermined number of rotations or less during the dewatering stroke.

A laundry machine comprising a dynamically suspended assembly including a drum for holding laundry, rotationally mounted with the dynamically suspended assembly, a supporting structure for the dynamically suspended assembly, and at least one suspension assembly coupled between the dynamically suspended assembly and the supporting structure for supporting the dynamically suspended assembly, with a load sensor between the suspension assembly and the supporting structure or between the suspension assembly and the dynamically suspended assembly.
