Abstract
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.
Claims16
A laundry treating apparatus comprising:
- a casing;
- a tub disposed in the casing and configured to receive laundry;
- a ball balancer disposed in at least one side of the tub, the ball balancer comprising a plurality of balls and a guide part that is configured to guide movement of the plurality of balls;
- a door attached to the casing and configured to be opened and closed;
- a motor configured to rotate the tub;
- and
- a control unit configured to:
- control the tub to rotate at a first speed in a blanket dehydration mode, wherein the plurality of balls are configured to, based on the tub rotating at the first speed, gather and rotate along the guide part,
- control the tub to rotate at a second speed lower than the first speed based on an amount of eccentricity of the laundry in the tub becoming greater than or equal to a first reference value while the tub rotates at the first speed, wherein the plurality of balls are configured to, based on the tub rotating at the second speed, separate from one another and rotate along the guide part, and
- control the tub to rotate at a third speed higher than the first speed based on the amount of eccentricity of the laundry in the tub becoming less than or equal to a second reference value while the tub rotates at the second speed, wherein the plurality of balls are configured to, based on the tub rotating at the third speed, separate from one another and rotate along the guide part.

- control the tub to rotate at a second speed lower than the first speed based on an amount of eccentricity becoming greater than or equal to a first reference value while the tub rotates at the first speed, wherein the plurality of balls are configured to, based on the tub rotating at the second speed, be spaced apart from one another and rotate along the guide part, and
- control the tub to rotate at a third speed higher than the first speed based on the amount of eccentricity becoming less than the first reference value while the tub rotates at the first speed, wherein the plurality of balls are configured to, based on the tub rotating at the third speed, be spaced apart from one another and rotate along the guide part.
