  • Publication number: 20240093534
    Abstract: A door-locking module for a door of a household appliance includes a housing; a printed circuit board (PCB), received within the housing and further includes at least one first actuator switch adapted to open and close a predetermined first circuit of the PCB. A locking pin is configured to move between a locked position, affecting the door into a locked state, and an unlocked position, affecting the door into an unlocked state. An actuator is operably coupled to the locking pin so as to controllably move the locking pin between the unlocked position and the locked position. A locking ring is operably coupled between the actuator and the at least one first actuator switch and includes a trigger member adapted to operably engage with the signal actuator, and at least one cam guide adapted to cooperate with a corresponding cam follower of the locking pin.

  • Patent number: 11846063
    Abstract: A lock switch module for an appliance door-lock is provided. The lock switch module may include a PCB (printed circuit board) with an insulating support, multiple conductive tracks applied to the insulating support, an electrical connector, multiple terminals connected to respective conductive tracks, and a door-lock switch that is electrically connected between two of the conductive tracks. A locking pin can move between retracted and extracted positions and cooperate with the door-lock switch to correspondingly change the door-lock switch's state. A low voltage electric motor has a rotating output shaft and is connected electrically to at least two conductive tracks of the PCB. A transmission mechanism is operatively positioned between the output shaft of the electric motor and the locking pin to drive, following the actuation of the electric motor, the movement of the locking pin between the retracted and extracted positions.
