Motorized oven lock for sealing oven door

An oven lock mechanism for use with an oven having a door and a frame surrounding a cooking chamber having an opening selectively closed by engagement of the door with the frame, the lock mechanism comprising:

• a mounting plate mounted to the frame;
• a latch mounted to the mounting plate for movement about a pivot axis and rotatable about the pivot axis between an unlatched and latched position, the latch including a follower surface offset from the pivot axis;
• an actuator pin movably supported by the mounting plate, the actuator pin having an outer end extending beyond the mounting plate for engaging the oven door upon closure and a cam end engaging the follower surface for rotating the latch into the latched position wherein the door is adapted to be captured by the latch;
• a blocker selectably movable into a blocking position when the latch is in a latched position for interfering with the rotation of the latch such that the latch is locked into the latched position for locking the oven door in a closed position and
• an electromechanical actuator mounted to the base plate, the actuator moving the blocker and wherein movement of the blocker into the blocking position induces additional movement of the latch to pull the oven door closer to the frame.

An oven lock mechanism for use with a self-cleaning oven having a door for selectively closing an opening of a cooking compartment surrounded by a frame and a compressible seal, the oven lock mechanism comprising:

• a mounting plate coupled to the frame near the oven compartment opening;
• a latch pivotably mounted to the mounting plate about a pivot axis and rotatable between an unlatched and latched position, the latch including a follower surface offset from the pivot axis;
• a blockable member mounted for movement relative to the mounting plate the blockable member being coupled to the latch so that when movement of the blockable member is blocked, movement of the latch from the latched to the unlatched position is inhibited;
• an actuator pin movably supported by the mounting plate, the actuator pin having an outer end extending beyond the mounting plate for engaging the oven door upon closure and a cam end engaging the follower surface for rotating the latch into the latched position wherein the door is adapted to be captured by the latch;
• and
• a blocker mounted for movement relative to the mounting plate to selectively block and unblock the blockable member;
• and
• a motor coupled to the mounting plate, the motor when actuated moving the blocker and wherein movement of the blocker induces additional movement of the latch from the latched position to a position wherein the oven door engages and compresses the seal.

An oven lock mechanism for use with an oven having a door and a frame surrounding a cooking chamber having an opening selectively closed by engagement of the door with the frame, the lock mechanism comprising:

• a mounting plate mounted to the frame;
• a latch mounted to the mounting plate for movement about a pivot axis extending through the latch and pivotable about the pivot axis between an unlatched and latched position, the latch including a follower surface offset from the pivot axis;
• an actuator pin supported for movement upon closure of the oven door, the actuator pin having a cam end engaging the follower surface of the latch upon closure of the oven door for urging the latch to pivot into the latched position wherein the door is adapted to be captured by the latch;
• a blocker selectably movable into a blocking position when the latch is in a latched position for interfering with the rotation of the latch such that the latch is locked into the latched position for locking the oven door in a closed position;
• and
• an electromechanical actuator mounted to the base plate, the actuator moving the blocker and wherein movement of the blocker into the blocking position induces additional movement of the latch to pull the oven door closer to the frame.
