Latching system for an appliance

A latching system for an appliance comprising at least a first oven, a first door for the first oven, a second oven and a second door for the second oven, the latching system comprising:

• a master latch assembly for locking the first door when the first door is fully closed, the master latch assembly comprising a handle member and a latch pawl, wherein
• a first end of the latch pawl including a first notch and a second notch, the second notch being disposed adjacent to the first notch, the first notch and the second notch both being of a shape allowing door engagement and open in the same direction, wherein if the first door is not fully closed, the handle member is prevented from being moved to the fully locked position by engagement of the first notch with the first door thereby preventing engagement of the second notch with the first door and thereby preventing locking of the first door, and
• a second end of the latch pawl being pivotably coupled to the handle member;
• a slave latch assembly for locking the second door when the second door is fully closed, the slave latch assembly comprising a link member and a latch pawl, wherein
• a first end of the latch pawl of the slave latch assembly including a first notch and a second notch, the second notch being disposed adjacent to the first notch, the first notch and the second notch both being of a shape allowing door engagement and open in the same direction, wherein if the second door is not fully closed, the handle member is prevented from being moved to the fully locked position by engagement of the first notch with the second door thereby preventing engagement of the second notch with the second door and thereby preventing locking of the second door, and
• a second end of the latch pawl of the slave latch assembly being pivotably coupled to the link member;
• a cable operatively coupling the master latch assembly and the slave latch assembly so that a movement of the master latch assembly between an unlocking position where the first door is unlocked and a locking position where the first door is locked generates a corresponding movement of the slave latch assembly between an unlocking position where the second door is unlocked and a locking position where the second door is locked;
• a position switch associated with one of the master latch assembly and the slave latch assembly and configured to detect when the one of the master latch assembly and the slave latch assembly is in its locking position;
• and
• a controller coupled to the position switch and configured to enable an operational mode of at least one of the first oven and the second oven when the position switch detects the one of the master latch assembly and the slave latch assembly is in its locking position in conjunction with a request for the operational mode.
