Oven appliance and a method for operating an oven appliance

1. A method for operating an oven appliance, the oven appliance including a cooking chamber for receipt of food items for cooking, the method comprising the steps of:

establishing a cook mode of the oven appliance;

measuring a temperature T initial ,

initiating a preheat cycle of the oven appliance;

counting a time t pre ;

determining whether time t pre has reached a threshold time t thr and, if so, then measuring a temperature T thr ;

determining whether the cooking chamber of the oven appliance is heavily loaded and, if so,

then notifying a user of the oven appliance.

2. The method of claim 1 , wherein the step of determining whether the cooking chamber is heavily loaded comprises calculating the difference between the temperatures T thr and T initial .

3. The method of claim 1 , wherein the cooking chamber is heavily loaded if the difference between the temperatures T thr and T initial is less than a value T base .

4. The method of claim 1 , further comprising the step of continuing the preheat cycle if the cooking chamber is not heavily loaded at the step of determining whether the cooking chamber is heavily loaded.

5. The method of claim 1 , wherein the step of notifying the user comprises displaying a notification.

6. The method of claim 1 , wherein the step of notifying the user comprises emitting an audible notification.

7. The method of claim 1 , further comprising the step of returning to the step of counting time t pre if time t pre has not reached time t thr at the step of determining whether time t pre has reached time t thr .

8. An oven appliance, comprising:

a cabinet, the cabinet defining a cooking chamber configured for receipt of food items for cooking;

a heating element configured to heat the cooking chamber;

a fan; and

a controller in operative communication with the heating element and the fan, the controller configured for

establishing a cook mode of the oven appliance;

measuring a temperature T initial ,

initiating a preheat cycle of the oven appliance;

counting a time t pre ;

determining whether time t pre has reached a threshold time t thr and, if so, then measuring a temperature T thr ;

determining whether the cooking chamber of the oven appliance is heavily loaded and, if so, then

notifying a user of the oven appliance.

9. The oven appliance of claim 8 , wherein determining whether the cooking chamber is heavily loaded comprises calculating the difference between the temperatures T thr and T initial .

10. The oven appliance of claim 8 , wherein the cooking chamber is heavily loaded if the difference between the temperatures T in , and T initial is less than a value T base .

11. The oven appliance of claim 8 , wherein the controller is further configured for continuing the preheat cycle if the controller determines the cooking chamber is not heavily loaded.

12. The oven appliance of claim 8 , wherein the controller is configured to display a notification to notify the user.

13. The oven appliance of claim 8 , wherein the controller is configured to emit an audible notification to notify the user.

14. An oven appliance, comprising:

a cabinet, the cabinet defining a cooking chamber configured for receipt of food items for cooking;

a heating element configured to heat the cooking chamber;

a fan; and

a controller in operative communication with the heating element and the fan, the controller configured for

establishing a cook mode of the oven appliance;

measuring a temperature T initial ;

initiating a preheat cycle of the oven appliance;

counting a time t pre ;

measuring a temperature T pre ;

determining whether the cooking chamber of the oven appliance is heavily loaded and, if so, then

notifying a user of the oven appliance.

15. The oven appliance of claim 14 , wherein the controller is further configured for continuing the preheat cycle if the controller determines the cooking chamber is not heavily loaded.

16. The oven appliance of claim 14 , wherein the controller is configured to display a notification to notify the user.

17. The oven appliance of claim 14 , wherein the controller is configured to emit an audible notification to notify the user.

18. The oven appliance of claim 14 , wherein the controller is further configured for, while counting the time t pre

determining whether the difference between temperature T pre and temperature T initial is at least a value T base and, if so, then recording a time t thr .

19. The oven appliance of claim 18 , wherein determining whether the cooking chamber is heavily loaded comprises comparing time t thr to a time t base .

20. The oven appliance of claim 18 , wherein the cooking chamber is heavily loaded if the time t thr is greater than a time t base .
