Abstract

For the automatic determination of the load of laundry introduced into the machine and hence for selecting the washing programme, the washing machine includes a means of measuring the driving torque of the drum at constant acceleration (t3, t4) of the drum. This enables the moment of inertia of the washing load about the rotation axis of the drum to be measured. <IMAGE>
