Abstract: A method of estimating water mass extraction in a laundry treating appliance having a drum at least partially defining a treating chamber for receiving a laundry load for treatment according to a cycle of operation, and a motor operably coupled with the drum to rotate the drum, where geometry changes in a laundry load affect inertia estimations. The method includes rotating the drum during a water extraction cycle to at least two distinct speeds, each for a dwell time, by way of at least one acceleration ramp and determining, during the rotation, by a controller communicably coupled with the motor, at least one of a torque of the motor, an acceleration of the drum, a speed of the drum, or an angular position of the drum. A parameter estimator estimates inertia values of a laundry load in the drum, based on at least one of the torque, acceleration, speed, or angular position of the drum at a beginning and an end of each dwell time. A water mass extraction is determined based on the estimated inertia values. The cycle of operation is adjusted based on the determined water mass extraction.

Abstract: A laundry treating appliance includes a drum at least partially defining a treating chamber for receiving a laundry load for treatment according to a cycle of operation, a motor operably coupled with the drum to rotate the drum, a controller coupled to the motor for controlling the motor and for determining at least one input sensed from the motor, and a processor operably coupled with the controller and having a parameter estimator to estimate parameter values of a laundry load based upon the at least one input. The processor is configured to send an excitation signal to the controller that randomly fluctuates an acceleration command to affect acceleration of the motor while the parameter values of the laundry load are estimated. The cycle of operation can then be adjusted based on the estimated parameter values of the laundry load.

Abstract: 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.

Abstract: A laundry washing machine and method implement dynamic damping force optimization during a wash cycle to optimize a force-generating operation such as a spin operation performed during the wash cycle. The dynamic damping force optimization may utilize inputs from a suspension force sensor in combination with an accelerometer to dynamically determine a damping capability for a suspension of a laundry washing machine such that damping in the suspension system may be maintained within the damping capability of the suspension system to balance operation performance against the generation of undesirable forces and vibrations.

Abstract: A dual-stroke safety switch of a washing machine has a control switch mounted in a base, and a control rod movably connected to the base. The control switch comprises a first control switch and a second switch. The control rod has two motion strokes respectively for controlling the switch-off of the first control switch and the second switch, and the motion stroke for the switch-off of the first control switch is less than the motion stroke for the switch-off of the second control switch. The different strokes of the control rod substantially reflect different degrees of eccentricity of a water tub. The switch-off of the first control switch indicates that small eccentricity of the water tub takes place, and the switch-off of the second control switch indicates that there is serious eccentricity.

Abstract: A method of estimating a water extraction profile in a laundry treating appliance includes accelerating rotation of the drum during a water extraction cycle, determining, during the accelerating rotation, a torque of the motor, an acceleration of the drum, a speed of the drum, and/or an angular position of the drum, and estimating with a parameter estimator, at multiple times during the accelerating rotation, inertia of a laundry load, based on the torque, acceleration, speed, and/or angular position of the drum to establish multiple inertia values. A water extraction profile is then estimated based on the inertia values.

Abstract: A suspender disengagement detection apparatus for a washing machine, comprising pressure sensors and a controller. The pressure sensors are electrically connected to the controller. The controller is electrically connected to a drive motor of the washing machine. In a working process of the washing machine, the pressure sensors are mounted on the joint of at least one suspender and the housing of the washing machine, and/or the joint of the suspender and the suspender base of the outer tub of the washing machine to detect a pressure, and a detection result is fed back to the controller; and the controller determines, whether a suspender is disengaged according to feedback information, and further controls the change in a working state of the drive motor of the washing machine.
