SISTEMA DI COMANDO PER ESSICCATORI PER BIANCHERIA ED ESSICCATORI DI BIANCHERIA PROVVISTI DI DETTO SISTEMA DI COMANDO

摘要

A clothes drier control circuit includes an electric heater regulated to maintain a constant predetermined temperature difference between the outlet and the ambient air. A digital reference value is stored representing the constant heat output level when a constant rate of evaporation is reached. The eventual reduction of the heat output to a given fraction of the reference value is detected so as to indicate that the clothes have reached a predetermined desired degree of dryness.
