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: A method for controlling a spin-drying operation of a washing apparatus includes a laundry dispersing step of dispersing the laundry inside a drum by accelerating the drum, a spin-drying step including detecting the eccentricity of the drum, and performing spin-drying by rotating the drum to a spin-drying RPM. The laundry dispersing step is re-executed when the eccentricity exceeds a reference eccentricity, and in the spin-drying step, a rotation time during which the drum rotates at the spin-drying RPM is adjusted according to a spin-drying degree. The spin-drying degree is measured after a point in time at which the eccentricity exceeds the reference eccentricity.

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: A washing machine includes a washing tub configured to accommodate laundry therein, a motor configured to rotate the washing tub, and a controller. The controller is configured to: determine a laundry amount and a laundry-tangled degree by using a plurality of types of data that are measured while rotating the washing tub at a specific rotational speed; set an allowable unbalance (UB) value corresponding to the laundry amount and the laundry-tangled degree; determine a UB value based on rotating the washing tub during a dewatering stroke; and control the motor to stop rotating the washing tub based on the UB value exceeding the allowable UB value.

Abstract: A method of controlling a drum type washing machine is disclosed. The method includes sensing laundry weight to perform a washing cycle (a laundry weight sensing step), immediately executing a first spin-drying pattern without additional laundry weight sensing when a laundry weight value sensed at the laundry weight sensing step is equal to or less than A in a spin-drying cycle, and executing a second spin-drying pattern after sensing the laundry weight when the laundry weight value sensed at the laundry weight sensing step is greater than A in the spin-drying cycle. In a case in which the laundry weight is low, spin-drying is immediately performed without performing laundry weight sensing, whereby it is possible to reduce time necessary to sense the laundry weight.
