Abstract: A washing machine includes a water storage tank, a vibration sensor provided to the water storage tank, a washing tub rotatably disposed in the water storage tank and configured to accommodate laundry therein, a motor configured to rotate the washing tub, and a controller. The controller is configured to: measure an unbalance (UB) value based on rotating the washing tub during a dewatering stroke; control the motor to stop rotating the washing tub based on the UB value exceeding an allowable UB value included in a preset UB table; measure a dewatering time of the laundry and a vibration value during the dewatering stroke using the vibration sensor; and change the allowable UB value included in the preset UB table based on the dewatering time and the vibration value.

Abstract: The laundry processing device according to the present invention comprises: a first washing unit for doing laundry; and a second washing unit having a washing space independent from the first washing unit and provided with a tub of a smaller capacity than the first washing unit, wherein the first washing unit comprises: a first display unit; a first laundry amount detecting unit for measuring the amount of laundry in the first washing unit; and a first control unit for displaying, on the first display unit, a guide message recommending use of the second washing unit if the amount of laundry measured by the first laundry amount detecting unit is less than a first set value. When the amount of laundry is relatively small, the user is induced to use the second washing unit, thereby reducing power consumption.

Abstract: Disclosed are a washing machine and a control method thereof, capable of preventing occurrence of an accident related to a child or a pet being inside a washing tub. A washing machine according to an aspect of the present disclosure includes a concentration sensing part configured to a sense a concentration of a specific component in air measured inside or outside the washing tub, a controller configured to switch the door and the washing tub to a safe mode based on the concentration of the specific component sensed by the concentration sensing part, and a release signal detector configured to detect a release signal for switching the door and the washing tub, which have been switched to the safe mode by the controller, back to a normal mode.
