Patent number: 11142860Abstract: There is proposed a washing machine and a control thereof capable of maximizing a mechanical force regardless of the amount and weight of laundry. By using a washing profile in which the cycle and size of a washing RPM are variable, a washing mechanical force can be maximized regardless of the amount of laundry or a change in the weight of the laundry due to moisture absorption of the laundry. In addition, the head drop behavior of the laundry can be diversified through the washing profile in which the cycle and size of the washing RPM are variable, and in this way, by allowing water (washing water) to be effectively infiltrated into the laundry, the washing performance can be improved. In addition, by continuously showing various washing operations (rubbing, tapping, centrifugal rotation, or the like), an effect of enhancing the visibility of washing can be obtained.Type: GrantFiled: July 3, 2017Date of Patent: October 12, 2021Assignee: Samsung Electronics Co., Ltd.Inventors: Jung Chul Choi, Jun Hyun Park, Wan Hee Lee
