Abstract: A method for detecting the standstill of a drum in a tumble drier during the drying of damp laundry by means of process air which is heated by a heating device in an inflow channel in front of the drum and passes into an outflow channel after passage through the drum, wherein the conductivity of the laundry is measured in the drum and the change in the conductivity is evaluated with regard to the detection of the standstill of the drum. Here, the temperature of the process air is measured by means of a temperature sensor which is arranged in the outflow channel after the drum, and the change in the temperature of the process air is evaluated with regard to the detection of the standstill of the drum. The invention also relates to a tumble drier which is suitable for this purpose.
