Patent ID: 8420957

Claim:
A method for weighing laundry inside a washing machine, comprising: a first step of a distribution of laundry in a basket of a washing machine by rotation said basket at a first angular rotation speed ω 1 , a second step of rotating said basket at a second angular rotation speed ω 2 that is higher than said first angular rotation speed ω 1 so that the mass of laundry is distributed in a stable and substantially balanced manner against an internal surface of the basket thereby to provide a flywheel of laundry with a constant moment of inertia; and a third step of measurement of an energy absorbed by a motor drive for moving the basket of the washing machine during an angular acceleration of the loaded basket at a third angular rotation speed ω 3 and a fourth angular rotation speed ω 4 each having a value between said first and second angular rotation speeds ω 1 , ω 2 .
