Abstract: A washing machine includes a drum accommodating laundry, a motor configured to rotate the drum, a speed sensor configured to detect a rotational speed of the drum, and a processor. The processor configured to: determine a mass of the laundry corresponding to each of a first acceleration section and a second acceleration section based on the rotational speed detected by the speed sensor, and control the motor such that an absolute value of the rotational speed at a start time of the first acceleration section is substantially the same as an absolute value of a rotational speed at a start time of the second acceleration section. A rotational direction of the drum corresponding to the rotational speed at the start time of the first acceleration section is opposite to a rotational direction of the drum corresponding to the rotational speed at the start time of the second acceleration section.

Abstract: A clothes care device is provided. The clothes care device includes a collection box, a suction pipe, a washing cover, and a spray nozzle disposed inside the suction pipe and provided in such a way that an end of the spray nozzle faces a washing port, and the washing cover mounted to the washing port and provided to be pressed against clothes. By operating a washing water supply in a state in which the washing cover is pressed against the clothes by an operation of a suction device, the spray nozzle sprays washing water and the suction device suctions and collects the washing water.

Abstract: Disclosed herein is a washing machine capable of appropriately identifying the presence or absence of waterproof clothing. The washing machine includes a cabinet, an outer tub elastically supported on the inside of the cabinet, an inner tub rotatably provided inside of the water tub, a motor configured to rotate the inner tub, a vibration sensor provided in the outer tub, a rotation sensor provided in the motor; and a at least one processor electrically connected to the vibration sensor, the rotation sensor and the motor and configured to control a rotation speed of the motor based on a vibration of the outer tub detected by the vibration sensor and a rotation of the motor detected by the rotation sensor.
