WASHING MACHINE AND METHOD OF CONTROLLING THE SAME

摘要

A laundry washing machine and a control method are provided to increase the efficiency of the washing by performing the swelling process for the estimated time. A laundry washing machine comprises a contamination sensor(22) and a controller. The contamination sensor senses a pollution level of the water in which the laundry is dipped. The contamination sensor is the sensor detecting the turbidity of the water. The controller determines that the swelling state of the laundry is the saturation, if the change rate of the pollution level of the water is under the pre-set value. The controller makes the swelling process complete, if the swelling state of the laundry is the saturation. The controller displays the detergent amount and the washing process time based on the pollution level of the water determined when the swelling state of the laundry is the saturation.
