Abstract

A door locking means for a washing and/or drying machine for laundry, adapted to keep the door locked during the washing or drying cycle selected and to unlock the door after the end of the cycle or if the door is prematurely opened during the washing or drying cycle. The means comprises a bimetallic element (5) associated both with a pin (12) interacting with the lock (13) of the door, and with an electric contact (8) connected before the general switch (4) of the machine and adapted to be closed on a conventional-type optical or acoustic warning means (11) adapted to signal the locked or unlocked state of the door. The bimetallic element (5) is furthermore provided with an electric contact (1) adapted to be closed on the electric components of the machine and to be activated by the element simultaneously with the other electric contact (8). In this way the warning means (11) is switched on and off when the contact (7) of the bimetallic element (5) is closed and open, respectively, in the particular locked or unlocked state of the door, thereby preventing any incorrect activation of the door.
