Abstract: PURPOSE: A detecting method of the washing amount for a drum washing machine is provided to improve the reliability by detecting the washing amount differently and repeatedly. CONSTITUTION: A microcomputer checks a time to reach an inner tub at a specific speed. The washing amount is discriminated by comparing the checked time with a predetermined time.
