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.

Washing machine and method for controlling the same

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.

Laundry treatment device and control method thereof

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.

Laundry processing device and method for controlling same

The laundry treatment machine includes an inverter to convert direct current (DC) voltage into alternating current (AC) voltage and to output the AC voltage to a motor. The laundry treatment machine includes an inverter controller to control the inverter to supply current corresponding to a direction opposite to back electromotive force generated from the motor to the motor so as to align the motor during a starting operation of the motor. It is feasible to rapidly align a rotor of the motor during the starting operation of the motor.
