Abstract
The invention concerns an automatic oven door locking assembly for locking an oven door. The locking assembly includes a mounting plate, a switch and a latch plate. The latch plate has a hook engageable with an anchor in the oven door, and is moveable between positions where the hook disengages or engages the anchor. The assembly also includes a cam that is rotatably driven by a drive shaft and operatively connected to the latch plate so that when the cam rotates the latch plate moves from one position to another. The cam has an eccentric extension that engages and disengages the switch when the cam rotates. The assembly further includes biasing means to urge the movement of the latch plate from one position to another so that a portion of the latch plate disengages or engages the switch.
Claims18
An automatic oven door locking assembly for locking an oven door, said locking assembly comprising:
- a mounting plate to mount the locking assembly within the oven;
- a switch with an on position and an off position mounted to the mounting plate to respectively send an on signal and an off signal to an oven processor;
- a latch plate operatively mounted to the mounting plate, the latch plate having a hook engageable with an anchor point within the oven to lock the oven door;
- the latch plate being moveable between a first position where the hook disengages the anchor point and a second position where the hook engages the anchor point, the latch plate being also movable between said first position and a third position where a portion of the latch plate engages the switch and turns the switch to said on position;
- a cam mounted to a drive shaft and rotatably driven thereby, the cam being operatively connected to the latch plate so that when the cam rotates the latch plate moves between said first and second position, the cam having at least one eccentric extension that alternately engages and disengages the switch when the cam rotates, thereby alternately turning the switch to the on and off position,
- biasing means operatively connected to the latch plate to urge the movement of the latch plate from the first position to said third position when the oven door is open, the latch plate being brought back to the first position upon closing the oven door.
