Oven appliances and methods of automatic reverse sear cooking
An oven appliance may include a cabinet, a plurality of chamber walls, a heating element, and a controller. The plurality of chamber walls may be mounted within the cabinet. The plurality of chamber walls may define a cooking chamber. The heating element may be mounted within the cooking chamber. The controller may be in operable communication with the heating element. The controller may be configured to initiate a cooking operation that includes receiving a user selection signal indicating an automatic cooking cycle a food item receivable within the cooking chamber, directing the heating element according to a first slow-cook stage, detecting a first threshold condition of the food item within the cooking chamber during the first slow-cook stage, the first threshold condition corresponding to the user selection signal, and directing the heating element according to a second sear stage in response to detecting the first threshold condition.
1. An oven appliance comprising:
a cabinet;
a plurality of chamber walls mounted within the cabinet, the plurality of chamber walls defining a cooking chamber;
a heating element mounted within the cooking chamber; and
a controller in operable communication with the heating element, the controller being configured to initiate a cooking operation comprising
receiving a user selection signal indicating an automatic cooking cycle for a food item receivable within the cooking chamber,
directing the heating element according to a first slow-cook stage,
detecting a first threshold condition of the food item within the cooking chamber during the first slow-cook stage, the first threshold condition corresponding to the user selection signal,
directing the heating element according to a second sear stage in response to detecting the first threshold condition, and
detecting a second threshold condition during the second sear stage,
wherein the second threshold condition is a maximum time period of the second sear stage, and
wherein detecting the second threshold condition comprises measuring elapsed time of the second sear stage greater than or equal to the maximum time period.
2. The oven appliance of claim 1 , further comprising a temperature sensor in thermal communication with the food item, wherein detecting the first threshold condition comprises measuring a food temperature greater than or equal to a first temperature threshold at the food item.
3. The oven appliance of claim 1 , further comprising a camera assembly directed at the cooking chamber, wherein detecting the first threshold condition comprises
obtaining an image of the food item, and
analyzing the image to identify a visual indicator of the food item.
4. The oven appliance of claim 1 , wherein the heating element is a top heating element disposed above the food item, wherein the oven appliance further comprises a bottom heating element disposed below the food item, and wherein directing the heating element according to the second sear stage comprises holding the bottom heating element in an inactive state for a duration of the second sear stage.
5. The oven appliance of claim 1 , wherein the cooking operation further comprises halting activation of the heating element in response to detecting the second threshold condition.
6. The oven appliance of claim 1 , wherein the cooking operation further comprises transmitting an alert signal in response to detecting the second threshold condition.
7. The oven appliance of claim 1 , further comprising a temperature sensor in thermal communication with the food item, wherein detecting the first threshold condition comprises measuring a food temperature greater than or equal to a first temperature threshold at the food item.
8. The oven appliance of claim 1 , wherein the first threshold condition is a maximum time period of the first slow-cook stage, and wherein detecting the first threshold condition comprises measuring elapsed time of the first slow-cook stage greater than or equal to the maximum time period.
