Method for controlling spin-drying operation of washing apparatus
11098431 · 2021-08-24 · ·

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.

A laundry apparatus includes a tub, a drum, a control unit, a motor, and a dynamic balancing assembly. The drum is positioned within a fluid containment envelope of the tub and rotatable relative to the tub about a primary rotation axis. The motor is coupled to the tub and operatively coupled to the drum to cause rotation of the drum. The dynamic balancing assembly includes an orbital balancing passage arranged concentrically around the motor, a first counterweight device, and a second counterweight device. The first and second counterweight devices are positioned within the orbital balancing passage and are responsive to the control unit to move the first and second counterweight devices along the orbital balancing passage to adjust an angular position of the first and second counterweight devices. A cross-sectional plane passes through the dynamic balancing assembly, the motor, and the fluid containment envelope of the tub.

The present invention relates to a laundry treating apparatus. The laundry treating apparatus according to an embodiment of the present invention includes a control unit which controls the tub to rotate at a first speed in a case of a blanket dehydration mode, to rotate at a second speed lower than the first speed so that the plurality of balls are dispersed when amount of eccentricity in the first speed rotation is equal to or greater than a first reference value, and to rotate at a third speed higher than the first speed when the amount of eccentricity in the first speed rotation is less than the first reference value. Accordingly, in a blanket dehydration mode, it is possible to stably perform dehydration by preventing the plurality of balls from operating unbalanced.
