Abstract
A control apparatus for a laundry washing and/or drying machine which is adapted to identify the type of fabrics to be laundered or dried and to automatically select the most suitable program cycle for the laundering or drying of the laundry. The apparatus includes a digital counter (10) and a discharge element (2) connected in parallel to sensors (5, 6) for measuring the electrostatic charge of the laundry produced during rotation of the drum. The discharge element produces a sudden discharge of the electrostatic charge accumulated in the course of different periods of time, the lengths of which depend on the type of fabrics to be laundered or dried. The apparatus also includes a digital comparator (12) which compares the number of clock signals counted by the digital counter (10) between discharge operations of the discharge element (2) to predetermined voltage levels, for controlling, by way of respective logic AND gates (13, 14), the execution of the most suitable program cycle for the laundering or drying of any fabric thus identified.
