OPERATING AND CONTROLLING METHOD FOR WASHING MACHINE

摘要

PURPOSE: An operation and control method of a washing machine is provided to independently drive two drums in a washing step in order to induce the rotation of the washing target by a relative rotation speed difference between the drums, thereby improving washing performance by rotating the washing target inside the drum and generating a three dimensional flow, and reducing the washing time. CONSTITUTION: An operation method of a washing machine includes a washing step(S100) performing a washing process by supplying the washing water and the detergent, a rinse step(S200) performing the rinse process by supplying a rinse water, and a dehydration step(S300) performing a dehydration process by draining the rinse water. The washing step rotates the washing target by a mutually independent relative motion of a main drum and a sub drum, and includes three dimensional laundry process(S110) which flows in a columnar direction and an axial direction. The washing step performs the washing process by supplying the washing water and the detergent. The washing step is able to include a general laundry process(S120) which flows the washing target in the columnar direction by a rotation of the main drum and the sub drum. The washing step is able to reciprocally perform the three dimensional laundry process and the general laundry process.
