Abstract
A door locking device for a door of a household appliance includes a door sensing contact having an engaged configuration and a disengaged configuration, a sensing pin configured to activate the disengaged configuration of the door sensing contact when the door is opened, a main power contact having an engaged configuration and a disengaged configuration, a cut-out trigger configured to activate the disengaged configuration of the main power contact when the door is open, a cut-out pin configured to disengage the main power contact and the door sensing contact when the door is forcibly opened, a locking pin moveable between a door-locked and a door-unlocked position.
Claims16
A door locking device for a door of a household appliance, comprising:
- a door sensing contact having an engaged configuration and a disengaged configuration;
- a sensing pin configured to activate the disengaged configuration of the door sensing contact when the door is opened;
- a main power contact having an engaged configuration and a disengaged configuration;
- a cut-out trigger configured to activate the disengaged configuration of the main power contact;
- a cut-out pin configured to disengage the main power contact and the door sensing contact when the door is forcibly opened;
- a locking pin moveable between a door-locked and a door-unlocked position;
- a coupling member, which is operably engageable with the cut-out trigger and the locking pin, such that when the locking pin is in the door-unlocked position, the cut-out trigger activates the disengaged configuration of the main power contact;
- and
- an electromagnetic driving mechanism adapted to actuate the coupling member between a first position and a second position, wherein in the first position the coupling member urges the locking pin into the door-locked position and urges the cut-out trigger away from the main power contact.
A door locking device for a door of a household appliance, comprising:
- a door sensing contact having an engaged configuration and a disengaged configuration;
- a sensing pin configured to activate the disengaged configuration of the door sensing contact when the door is opened;
- a main power contact having an engaged configuration and a disengaged configuration;
- a cut-out trigger configured to activate the disengaged configuration of the main power contact;
- a cut-out pin configured to disengage the main power contact and the door sensing contact when the door is opened, wherein the cut-out trigger further comprises a leg which is configured to arrest the sensing pin when the door is locked;
- a locking pin moveable between a door-locked and a door-unlocked position;
- a coupling member, which is operably engageable with the cut-out trigger and the locking pin, such that when the locking pin is in the door-unlocked position, the cut-out trigger activates the disengaged configuration of the main power contact;
- and
- an electromagnetic driving mechanism adapted to actuate the coupling member between a first position and a second position, wherein in the first position the coupling member urges the locking pin into the door-locked position and urges the cut-out trigger away from the main power contact.
