Range door lock with nuisance latch

An oven door locking mechanism, comprising:

• a mounting bracket defining a guide hole;
• a latch mechanism pivotally mounted to said mounting bracket including a link arm defining a lock hole adapted to align substantially coaxially with said guide hole;
• and
• a lock mechanism including a first thermally responsive element with a lock member affixed thereto adapted to be received through said guide hole and said lock hole, in response to actuation of said thermally responsive element, and
• a second thermally responsive element adapted to prevent actuation of said latch mechanism.

An oven door locking mechanism comprising:

• a mounting bracket including first and second mounting surfaces, an upwardly depending flange defining a notch, and a mounting flange, said mounting bracket defining a guide hole;
• a latch mechanism pivotally mounted to said first mounting surface, said latch mechanism including a link arm having an edge and defining a lock hole adapted to align substantially coaxially with said guide hole when said edge is received within said notch;
• a lock mechanism separably attached to said mounting flange, said lock mechanism including a housing with a catch adapted to engage a cavity wall to be heated, a bimetallic leaf mounted to said housing, and a lock pin affixed to said bimetallic leaf adapted to deflect in response to heating said bimetallic leaf;
• a switch affixed to said mounting bracket adapted to monitor one of a latched and an unlatched state of said latch mechanism;
• and
• an insulation pad sandwiched between said switch and said mounting bracket.

An oven door locking mechanism, comprising:

• a mounting bracket including first and second mounting surfaces,
• an upwardly depending flange defining a first notch, a mounting flange and plural assembly flanges, said mounting bracket defining a guide hole;
• a latch mechanism pivotally mounted to said first mounting surface, said latch mechanism including a link arm having an edge adapted to engage said first notch, said link arm defining a lock hole adapted to align substantially coaxially with said guide hole when said edge is in engagement with said first notch;
• a lock mechanism separably attached to said mounting flange against said second mounting surface, said lock mechanism including a housing, a catch attached to said housing adapted to be assembled to a wall of a cavity to be heated, a first bimetallic leaf mounted to said housing and having a flange adapted to be received against said wall, and a lock pin affixed to said first bimetallic leaf adapted to be deflected in response to heating said first bimetallic leaf;
• a second bimetallic leaf adapted to deflect into engagement with a second notch defined in said latch mechanism to selectively prevent actuation of said latch mechanism;
• a switch affixed to said mounting bracket adapted to monitor one of a latched or unlatched state of said latch mechanism;
• and
• an insulation pad sandwiched between said switch and said mounting bracket.
