Abstract

A cooking appliance includes a cabinet defining an oven cavity, a door attached to the cabinet for selectively exposing and sealing the oven cavity, a cooking element mounted to the cabinet for heating the oven cavity, a control system for controlling the cooking appliance and a display. The display is adapted to show a first series of images corresponding to a first operating stage and a second series of images corresponding to a second operating stage, wherein the first series of images is distinct from the second series of images such that a user may readily identify a current operating stage of the cooking appliance, even from a distance, based on the series of images being displayed.

Claims

1. A method of monitoring a cooking appliance having a oven cavity, at least one heating element, a controller and a display for cooking food during a cooking operation having multiple operating stages, said method comprising:

initiating a first operating stage of said cooking appliance;

presenting on said display a first series of images indicating operation of the cooking appliance in the first operating stage;

initiating a second operating stage of said cooking appliance;

presenting on said display a second series of images indicating operation of the cooking appliance in the second operating stage, wherein said first series of images is distinct from said second series of images such that a user can distinguish between the first and second operating stages of the cooking appliance, even from a distance, based on a particular series of images being displayed.

2. The method of claim 1, wherein said first operating stage of the cooking appliance is a preheat stage.

3. The method of claim 2, further comprising:

presenting said first series of images as a series of images of multiple lines, with each image having a progressively higher intensity of lines to portray the preheating of the oven cavity.

4. The method of claim 2, further comprising:

repeatedly displaying said first series of images during said preheat stage of the cooking appliance, wherein said first series of images is repeatedly displayed progressively faster as the preheat stage progresses.

5. The method of claim 1, wherein said second operating stage of the cooking appliance is a cooking stage.

6. The method of claim 5, further comprising:

presenting said second series of images as a series of images of flames, wherein the series of images appears as flickering flames when shown in sequence.

7. The method of claim 5, further comprising:

repeatedly displaying said second series of images during said cooking stage of the cooking appliance.

8. The method of claim 1, further comprising:

presenting on said display a third series of images for indicating a third operating stage of the cooking appliance.

9. The method of claim 8, wherein said third stage is a warming stage.

10. The method of claim 9, further comprising:

repeatedly displaying said third series of images during said warming stage of the cooking appliance.

11. The method of claim 1, wherein each of the first and second series of images are displayed as a continuous animation.

12. A cooking appliance comprising:

a cabinet defining an oven cavity;

a door attached to the cabinet for selectively exposing and sealing the oven cavity;

a heating element supported by the cabinet for heating the oven cavity;

a control system establishing a cooking operation having multiple operating stages for the cooking appliance; and

a display presenting a first series of images corresponding to a first operating stage and a second series of images corresponding to a second operating stage, wherein said first series of images is distinct from said second series of images such that a user can distinguish between the first and second operating stages of the cooking appliance, even from a distance, based on a particular series of images being displayed.

13. The cooking appliance according to claim 12, wherein said first operating stage of the cooking appliance is a preheat stage.

14. The cooking appliance according to claim 13, wherein said first series of images is a series of images of multiple lines, with each image having progressively higher intensity to portray the preheating of the oven cavity.

15. The cooking appliance according to claim 13, wherein said first series of images is displayed repeatedly during said preheat stage of the cooking appliance, and wherein said first series of images is repeatedly displayed progressively faster as the preheat stage progresses.

16. The cooking appliance according to claim 12, wherein said second operating stage of the cooking appliance is a cooking stage.

17. The cooking appliance according to claim 16, wherein said second series of images is a series of images of flames, wherein the series of images appears as flickering flames when shown in sequence.

18. The cooking appliance according to claim 16, wherein said second series of images is displayed repeatedly during said cooking stage of the cooking appliance.

19. The cooking appliance according to claim 12, wherein said display further displays a third series of images for indicating a third operating stage of the cooking appliance.

20. The cooking appliance according to claim 19, wherein said third operating stage is a warming stage.

21. The cooking appliance according to claim 20, wherein said third series of images is displayed repeatedly during said warming stage of the cooking appliance.

22. The cooking appliance according to claim 12, wherein each of the first and second series of images are displayed as a continuous animation.
