control of operations performed in domestic laundry dryers D06F58/32) - D06F: LAUNDERING, DRYING, IRONING, PRESSING OR FOLDING TEXTILE ARTICLES ## Abstract A method and apparatus for operating a laundry treating appliance having a tub and a rotatably wash basket, the method comprising draining at least a portion of a wash liquid, accelerating the wash basket, enabling the wash basket to decelerate and supplying a rinse liquid during at least a portion of the deceleration of the wash basket. ## Claims ### Claim 1 A method of operating a laundry treating appliance having a tub defining an interior, with a wash basket rotatably mounted within the interior and at least partially defining a treating chamber for receiving laundry for treatment in accordance with a cycle of operation, the tub having a wash liquid, the method comprising: a) draining at least a portion of the wash liquid from the tub; b) accelerating the wash basket to a first wash basket rotation speed; c) enabling the wash basket to decelerate from the first wash basket rotation speed to a wash basket rotation speed less than the first wash basket rotation speed; d) supplying a rinse liquid to the tub during at least a portion of the deceleration of the wash basket from the first wash basket rotation speed; and e) repeating steps a) through d), wherein the repeated b) accelerating the wash basket includes accelerating the wash basket to successively higher wash basket rotation speeds. ### Claim 2 (depends on 1) The method of claim 1 wherein the wash liquid comprises at least one surfactant. ### Claim 3 (depends on 1) The method of claim 1, further comprising accelerating the wash basket to a second wash basket rotation speed, higher than the first wash basket rotation speed, subsequent to the accelerating of the wash basket to the first wash basket rotation speed, and supplying a rinse liquid to the tub during at least a portion of a deceleration of the wash basket from the second wash basket rotation speed. ### Claim 4 (depends on 3) The method of claim 3, further comprising accelerating the wash basket to a third wash basket rotation speed, higher than the second wash basket rotation speed, subsequent to the accelerating of the wash basket to the second wash basket rotation speed, and supplying a rinse liquid to the tub during at least a portion of a deceleration of the wash basket from the third wash basket rotation speed. ### Claim 5 (depends on 1) The method of claim 1 wherein supplying a rinse liquid to the tub comprises at least one of supplying rinse liquid to a space between the tub and the wash basket, an exterior surface of the wash basket, an interior surface of the wash basket, the treating chamber, an internal surface of the tub, and combinations thereof. ### Claim 6 (depends on 1) The method of claim 1, further comprising accelerating the wash basket to an extraction speed to extract liquid from the laundry. ### Claim 7 (depends on 1) The method of claim 1 wherein enabling the wash basket to decelerate comprises at least one of passive deceleration during coasting and active deceleration during braking. ### Claim 8 A laundry treating appliance comprising: a tub defining an interior with a wash basket rotatably mounted within the interior and at least partially defining a treating chamber for receiving laundry for treatment with a wash liquid in accordance with a cycle of operation; a motor operably coupled with the wash basket to rotate the wash basket within the tub; a liquid supply system configured to supply rinse liquid to the tub; a drain pump configured to drain wash liquid from the tub; and a controller configured to: a) drain at least a portion of the wash liquid from the tub; b) accelerate the wash basket to a first wash basket rotation speed; c) enable the wash basket to decelerate from the first wash basket rotation speed to a wash basket rotation speed less than the first wash basket rotation speed; and d) supply a rinse liquid to the tub during at least a portion of the deceleration of the wash basket from the first wash basket rotation speed; and e) repeating steps a) through d), wherein the repeated b) accelerating the wash basket includes accelerating the wash basket to successively higher wash basket rotation speeds. ### Claim 9 (depends on 8) The laundry treating appliance of claim 8 wherein the wash liquid comprises at least one surfactant. ### Claim 10 (depends on 8) The laundry treating appliance of claim 8 wherein the controller is further configured to accelerate the wash basket to a second wash basket rotation speed, higher than the first wash basket rotation speed, subsequent to the accelerating of the wash basket to the first wash basket rotation speed, and supply a rinse liquid to the tub during at least a portion of a deceleration of the wash basket from the second wash basket rotation speed. ### Claim 11 (depends on 10) The laundry treating appliance of claim 10 wherein the controller is further configured to accelerate the wash basket to a third wash basket rotation speed, higher than the second wash basket rotation speed, subsequent to the accelerating of the wash basket to the second wash basket rotation speed, and supply a rinse liquid to the tub during at least a portion of a deceleration of the wash basket from the third wash basket rotation speed. ### Claim 12 (depends on 8) The laundry treating appliance of claim 8 wherein the controller is further configured to at least one of deactivate the motor to passively decelerate the wash basket and actively decelerate the wash basket by braking. ### Claim 13 (depends on 8) The laundry treating appliance of claim 8 wherein the liquid supply system is configured to supply rinse liquid to at least one of a space between the tub and the wash basket, an exterior surface of the wash basket, an interior surface of the wash basket, the treating chamber, an internal surface of the tub, and combinations thereof during the supplying of a rinse liquid to the tub.
