WASHING MACHINE, METHOD AND PROGRAM FOR CONTROLLING THE ROTATION SPEED OF THE DRUM

摘要

A washing machine includes a drum (1) for being rotated with laundry (10) loaded therein, a drum container (3) for accommodating the drum (1), and supported from a housing (5) by a resilient supporting mechanism (4), a motor (2) for rotating the drum (1), a vibration sensor (6) for sensing a vibration of the drum container (3), a frequency component calculator (7) for calculating a frequency component value of a vibration sensed by the vibration sensor (6), and an rpm controller (8) for varying an rpm of the motor (2) in response to the frequency component value. The foregoing structure allows preventing the laundry (10) from sticking to the inner wall of drum (1), thereby improving washing power of the washing machine.
