Door-locking device with safety system

A door-locking device for a household appliance, said household appliance comprising a door, said door-locking device comprising an actuator;

• a blocking member, driven by said actuator, said blocking member being capable of assuming a rest position and an engagement position, in which, when said door is closed, said blocking member engages with said door;
• a switch, capable of assuming a first state, in which the switch enables a power supply to said household appliance, and a second state, in which the switch disables the power supply to said household appliance;
• an activating assembly, coupled with said blocking member, the activating assembly comprising a rocker arm, rotatable on said blocking member about a pin, said rocker arm having a first end and a second end, and a pushing spring, arranged so that when said blocking member is in said rest position, said pushing spring is compressed and said blocking member is in said engagement position, said pushing spring exerts a force on said second end of said rocker arm;
• a detecting member for detecting the position of said door, the detecting member being movable relative to said blocking member, so as to assume, with respect to said blocking member, a first position, when said blocking member is in said engagement position, said detecting member is in said first position, and said door is closed, said activating assembly interferes with said switch, such that said switch assumes said first state;
• and when said blocking member is in said engagement position, said detecting member is in a second position, and said door is open, said activating assembly does not interfere with said switch, such that said switch assumes said second state;
• a containment enclosure;
• and a lever, wherein said blocking member has a constrained path, wherein said lever is pivoted at one end to said containment enclosure and has, at another end, a pawl constrained to move along said constrained path of said blocking member, said constrained path having a first portion, in which said pawl is arranged when said blocking member is in said rest position, thus holding said blocking member in said rest position and overcoming a force of said pushing spring, and a second portion, in which said pawl is arranged when said blocking member assumes the engagement position, and wherein said constrained path is located on a supporting base of said blocking member.
