Proximity sensing assembly for an oven appliance

An oven appliance defining a vertical direction, a lateral direction, and a transverse direction, the oven appliance comprising:

• a cabinet defining a cooking chamber;
• a cooktop positioned at a top of the cabinet and comprising one or more heating elements;
• a proximity sensing assembly defining an upper detection zone and a lower detection zone;
• and
• a controller in operative communication with the proximity sensing assembly, the controller being configured to:
• obtain an upper proximity reading in the upper detection zone using the proximity sensing assembly;
• obtain a lower proximity reading in the lower detection zone using the proximity sensing assembly;
• and
• implement a responsive action based on a combination of the upper proximity reading and the lower proximity reading.
