ABSTRACT:
A laundry machine with a reduced suds spin cycle includes a laundry basket to hold laundry which contains a liquid, typically a water/detergent solution. A tub surrounds the laundry basket. A circular drainage void is formed between the laundry basket and the tub. A motor, responsive to a control circuit, rotationally drives the laundry basket. The control circuit modulates the motor such that the laundry basket achieves a first rotational speed sufficient to force substantially all of the laundry against the wall of the laundry basket. Then, a second rotational speed, greater than the first rotational speed, forces the water/detergent solution from the laundry into the circular drainage void. An intermediate rotational speed, substantially equivalent to the first rotational speed, is then used while water/detergent solution is removed from the circular drainage void, inhibiting suds formation. A third rotational speed, greater than the second rotational speed, is then used to force additional water/detergent solution from the laundry into the circular drainage void. The intermediate rotational speed and water/detergent removal operation may then be repeated. Thereafter, an increased rotational speed may be used. Operating in this fashion, the laundry machine continuously removes water/detergent solution to inhibit suds formation. Thus, the detrimental effects of excessive suds is avoided.
