Abstract

An oven appliance may provide for a method of adaptive cooking. The method may include receiving an oven temperature signal to indicate an oven temperature and directing activation of a bottom heating element according to a first heating cycle based on the oven temperature signal. The method may further include receiving a bottom temperature signal to indicate a bottom temperature and directing activation of the bottom heating element according to a second heating cycle based on the bottom temperature signal, the second heating cycle being distinct from the first heating cycle.

5. The oven appliance of claim 1 , wherein the cooking operation further comprises determining the bottom temperature is below a minimum threshold, and

wherein the second heating cycle comprises activating the bottom heating element at a temperature-responsive condition based on a subsequent bottom temperature signal received from the bottom temperature sensor.

6. The oven appliance of claim 5 , wherein the second heating cycle comprises alternately directing the bottom heating element between an active state and an inactive state.

7. The oven appliance of claim 5 , wherein the second heating cycle comprises

holding the top heating element in an inactive state for an entire duration of the second heating cycle, and

directing the bottom heating element to an active state while the top heating element is in the inactive state.

8. The oven appliance of claim 1 , wherein the oven temperature signal is a first oven temperature signal, and wherein the cooking operation further comprises

receiving a second oven temperature signal from the oven temperature sensor subsequent to directing activation of the bottom heating element according to the second heating cycle, and

directing activation of the top heating element and the bottom heating element according to the first heating cycle based on the second oven temperature signal.

9. The oven appliance of claim 1 , wherein the bottom temperature signal is a first bottom temperature signal, and wherein the cooking operation further comprises

receiving a second bottom temperature signal from the bottom temperature sensor, and

directing activation of the bottom heating element according to the second heating cycle based on the second bottom temperature signal.

10. A method of operating an oven appliance comprising a plurality of chamber walls mounted within a cabinet and defining a cooking chamber, a cooking surface defined in the cooking chamber between a bottom wall and a top wall of the plurality of chamber walls, a top heating element mounted above the cooking surface to heat the cooking chamber, and a bottom heating element mounted below the cooking surface to heat the cooking surface, the method comprising:

receiving an oven temperature signal to indicate an oven temperature;
