Abstract

In a control means for a tumble dryer, wherein the temperature of air preheated by the drum is sensed up­ stream the heating means (6) and the temperature of the air discharged from the tumble dryer is sensed, the heating means (6) is de-energized when a first, presettable difference of these temperatures is reached, and the drum motor (4) and fan motor (5) is de-energized when a second, presettable difference of these temperatures is reached, the means for sensing the temperature differences is a mechanical measur­ ing and actuating means (2) operating on a change-over switch (1) the bistable switch (1) is coupled with a switching means (3) for sequentialiy switching the heating means (6) and the drum motor (4) and fan motor (5). The control means is mechanically simple and robust and constructed so as to be extensively free of servicing.
