摘要： 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.

摘要： Disclosed herein is a washing machine capable of identifying whether laundry of an inner tub includes waterproof clothing. The washing machine includes a cabinet provided with an opening at an upper portion thereof, an outer tub provided in the cabinet, an inner tub provided in the outer tub, a motor configured to rotate the inner tub, a camera configured to capture an image of an inside of the inner tub, and a controller configured to control the motor to increase a rotational speed of the inner tub to a first rotational speed during spinning. The controller is configured to control the motor to set the rotational speed of the inner tub to a second rotational speed, which is less than the first rotational speed, based on the image of the inside of the inner tub captured by the camera during the spinning.
