Abstract:
A drum type washing machine comprising:a drum rotatable about a horizontal or inclined center of rotation with laundry placed therein for washing the laundry and dewatering therefrom, a drive motor for rotating the drum, a plurality of liquid holding chambers arranged circumferentially of the drum at equal intervals for holding a liquid therein by a centrifugal force produced by the rotation of the drum, means for detecting an eccentric load due to uneven presence of the laundry within the drum, and control means for determining the position and magnitude of the eccentric load detected and adjusting the amounts of liquid in the liquid holding chambers in accordance with the position and magnitude of the eccentric load, the amounts of liquid in the liquid holding chambers being adjustable by braking the drum in rotation, the drum-type washing machine being characterized in that the machine has moment of inertia measuring means for detecting the rotation of the drum, the control means being operable to calculate the moment of inertia acting on the drum based on the rotation of the drum detected by the moment of inertia measuring means and to adjust the magnitude of braking force to be applied to the drum in accordance with the calculated moment of inertia so as to decelerate the drum at a constant rate in adjusting the amounts of liquid in the liquid holding chambers.
