Abstract:
1. A laundry machine configured to implement a plurality of washing courses each having at least one drum driving motion that rotates a drum to generate a corresponding mechanical force for washing laundry received in the drum, the plurality of washing courses comprising: a standard course implementing a first drum driving motion to rotate the drum and generate a first predetermined mechanical force for washing laundry; at least one weak course implementing a second drum driving motion to rotate the drum and generate a second predetermined mechanical force that is less than the first predetermined mechanical force of the standard course; and at least one strong course implementing a third drum driving motion to rotate the drum and generate a third predetermined mechanical force that is greater than the first predetermined mechanical force of the standard course, wherein the third drum driving motion comprises a step motion, the step motion including: rotating the drum in only one direction so that the laundry in the drum is lifted to a height greater than half a height of the drum; stopping the rotation of the drum before the laundry passes through a highest point of the drum to drop the laundry within the drum; and repeating the rotating the drum and the stopping the rotation of the drum.
