Abstract: Household washer-dryers include a laundry drum having an incoming air inlet and a waste air outlet, a blower in an air conduit, a heating device upstream of the air inlet, temperature and moisture sensors, a memory for measured values and process sequence variants and an electronic program control unit. A method for controlling drying processes in such devices includes measuring a waste air temperature at the air outlet at a starting point of a drying process. At least part of the heating device is periodically turned on and off during at least one time segment at a beginning of the drying process.

Abstract: A washing machine includes a perforated washing drum with a contact rpm at which items of laundry in the washing drum come to rest against a surface of the washing drum due to centrifugal force. The washing drum is intermittently driven in alternating rotary directions (reversing mode) during washing and/or rinsing, for accelerating the washing drum in one of the rotary directions to a first rpm being markedly below the contact rpm and accelerating the washing drum in the other of the rotary directions to a second rpm being markedly above the contact rpm.
