Abstract
An oven lock mechanism has a latch that is moved between an unlatched and a latched position and a blocker that blocks the latch in the latched position when a cleaning cycle is initiated. The latch is mounted for movement relative to the blocker to facilitate disengaging the latch from the blocker.
Claims20
An oven door lock mechanism for use with an oven having a door and a frame configured so that the door is adjacent the frame when the door is closed, the lock mechanism comprising:
- a latch coupled to the frame for movement between an unlatched and latched position, the latch including a latching member extending beyond the frame for interacting with the door;
- an actuator;
- a blocker coupled to the actuator, the blocker and actuator cooperating to move the blocker between a non-blocking position wherein the latch is free to move between the latched and unlatched position and a blocking position wherein the blocker blocks movement of the latch from the latched position to the unlatched position;
- and
- a release mechanism in operable engagement with the latch to move the latch, when the blocker is in the blocking position, to a disengaged position wherein the latch is disengaged from the blocker to enable the latch to move to the unlatched position.
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 moveable 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 blocked into the latched position for locking the oven door in a closed position;
- an electromechanical actuator mounted to the mounting plate, the actuator urging the blocker into the blocking position when actuated;
- and
- a release mechanism in operable engagement with the latch to move the latch, when the blocker is in the blocking position, to a disengaged position wherein the latch is disengaged from the blocker to enable the latch to move to the unlatched position.
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;
- a blocker mounted for movement relative to the mounting plate to selectively block and unblock the blockable member;
- a motor coupled to the mounting plate, the motor when actuated moving the blocker;
- and
- a release mechanism in operable engagement with the latch to move the latch, when the blocker is in the blocking position, to a disengaged position wherein the blockable member is disengaged from the blocker to enable the latch to move to the unlatched position.
