Door-lock with a hook detection slider with additional security

Abstract:

A door-lock for household appliances, comprising a casing (12) having an opening (14) for the insertion of a hook (15) carried by a door of a household appliance, a cam (16) rotatable between a retaining position and a release position, a locking slider (20) cooperating with said cam (16) and movable between an unlocking position and a locking position, wherein in the locking position the locking slider (20) locks the cam (16) in the retaining position, an electro-magnetic device comprising a housing (70) and a locking pin (28) for locking the locking slider (20) in the locking position, a door sensing slider (32) movable between an open door position and a closed door position, and a hook sensing slider (74) movable between an extracted position and a retracted position, wherein the hook sensing slider (74) has a projection (82) that prevents the movement of the door sensing slider (32) from the open door position towards the closed door position when the hook sensing slider (74) is in the extracted position, wherein the hook sensing slider (74) has a safety portion (86) that, in an abnormal condition in which the integrity of the cam support (11) is compromised, comes into contact with a side (94) of the housing (70) and prevents movement of the hook sensing slider (74) from the extracted position towards the retracted position.
