Abstract: A washing machine includes a drum for receiving laundry which washing machine not only prevents the laundry from becoming entangled in a complicated manner when the drum is rotated, but also beat-washes the laundry sufficiently. The washing machine includes a partition plate that is fixed to the inner circumferential surface of the drum and that divides the internal space of the drum into two washing compartments. The drum receives two washes in the respective washing compartments, and is rotated while reversing its rotation direction repeatedly. The partition plate and drum are rotated counterclockwise to an angle within a predetermined range and clockwise to an angle within a predetermined range. This allows the washing machine to repeat an operation of causing one of the two washes to slip down from a high position to be beat-washed and the other wash to be immersed in cleaning fluid for stain decomposition.
