Abstract
A method for determining an amount of laundry in an at least approximately horizontally supported drum for laundry being driven by a universal drive motor at a washing and drying rpm is performed on the basis of observations of parameters of an operation in a laundry handling machine. A drive moment at the drum drive motor is determined during a drum startup phase, for operating the drum at a controlled handling rpm at which the laundry is not held against a wall of the drum by centrifugal force.

In a method for determining an amount of laundry in a laundry handling machine, wherein the laundry is disposed in an at least approximately horizontally supported drum, and the drum is driven by a universal drive motor, and the amount of laundry is determined on the basis of observations of parameters of an operation in the laundry handling machine, the improvement which comprises:
- ascertaining a drive moment at the drum drive motor during a drum startup phase during which the drum is accelerated to a controlled treatment rpm at which the laundry is not held against a wall of the drum by centrifugal force;
- and
- determining the amount of laundry in the drum from the drive moment ascertained in the ascertaining step.
