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.
