Abstract: A washing machine and a method for controlling a washing machine are provided. The washing machine includes a frame configured to form an exterior, a tub installed in the frame, a drum accommodated in the tub, a washing motor configured to rotate the drum, a drain motor configured to drain water from the tub, a vibration sensor provided in the frame, memory storing one or more computer programs, and a controller coupled to the memory, the vibration sensor, the drain motor, and the washing motor, wherein the one or more computer programs include computer-executable instructions that, when executed by the controller cause the washing machine to drive the drain motor in a stopped state of the washing motor at a start of a spin-drying process, determine a resonant frequency of the frame based on a vibration value measured by the vibration sensor, and control a revolutions per minute (RPM) of the washing motor to avoid the resonant frequency during the spin-drying process.

Abstract: A washing machine may include a tub; a drum configured to be rotatable inside the tub; a weight balancer coupled to the tub; a vibration sensor provided in the tub; and a controller, wherein the controller is configured to compare an unbalance value of laundry in the drum with a reference value based on a driving current applied to a motor configured to rotate the drum, obtain an angular speed of at least one rotation axis of the tub based on an output value of the vibration sensor in response to the unbalance value of the laundry being less than the reference value, and determine whether the weight balancer is damaged based on the angular speed of the at least one rotation axis of the tub.

Abstract: A washing machine is provided. The washing machine includes a cabinet having an inlet through which laundry is inserted, a plurality of legs disposed under the cabinet and configured to support the cabinet, a tub provided inside the cabinet, a drum rotatable in the tub, and a drum motor configured to provide power to rotate the drum, a vibration sensor configured to detect vibrations occurring in the cabinet along at least two axes, memory storing one or more computer programs, and one or more processors communicatively coupled to the memory and the vibration sensor, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the washing machine to determine a leg that is not seated on an installation surface based on a phase difference between a first signal and a second signal output from the vibration sensor.

Abstract: A washing machine includes: a cabinet on a front side thereof with an inlet through which laundry is input; a tub inside the cabinet and having an opening corresponding to the inlet; a drum rotatably inside the tub; a motor configured to provide power for rotating the drum; a first vibration sensor configured to detect vibration generated from the tub; a second vibration sensor configured to detect vibration generated from the cabinet; and at least one processor. The at least one processor is configured to perform a spin-drying process according to a spin-drying profile defined by a rotational speed of the drum, and to control rotation of the drum based on a first vibration value corresponding to an output of the first vibration sensor and a second vibration value corresponding to an output of the second vibration sensor during a spin-drying process.

Abstract: A washing machine is provided. The washing machine includes a tub, a drum rotatably arranged within the tub, a drum motor for rotating the drum, a vibration sensor for sensing the vibration of the tub, and a control unit which maintains the rotation speed of the drum motor on the basis that the sensing value of the vibration sensor reaches a certain predetermined value during a dehydration operation, and which continuously maintains or increases the rotation speed of the drum motor based on the variation value of the sensing value of the vibration sensor.
