A front-loading clothes dryer, a horizontally pivotable door is secured in its closed position against accidentally opening by a latching closure. Moreover, the door is connected to a safety switch which cuts off or re-establishes power supply for the clothes dryer depending on whether the door is in the open or in the closed position. The object of the invention is to ensure that the switching function remains matched over the long term to the closure state of the door, as when the clothes dryer was manufactured. For that purpose, the functional elements for the latching closure and safety switch are arranged in direct proximity to each other but functionally separated into a component arranged on the door and a component arranged on the casing.

A method for detecting impermissible operating states in electronically controlled tumble dryers, in particular the state of motion of a laundry drum. In the method, the electrical conductivity of the laundry is determined by electrodes which touch the laundry, at least from time to time. The method is distinguished by the fact that, during the drying operation, the conductivity is periodically measured. The currently measured conductivity value is compared with at least one previously measured conductivity value and, if changes in conductivity that are determined from the compared values over a multi-period interval corresponds to a preset low range of fluctuation, an indication is given that the laundry drum is stationary.

A blower moves cooling air through the primary side of an air-to-air heat exchanger and process air the secondary side. The efficiency of the heat exchanger is increased in that the primary side is divided into at least two portions, through which the cooling air flows in series.
