Abstract

An automatic oven having a controller and a sensor assembly for automatically determining a food type for a food item placed in a cooking chamber of the automatic oven, and cooks the automatically determined food item according to a cooking profile selected based on the determined food type, while optionally accommodating a user input on the determining of the food type, and the cooking profile, including an optional degree of doneness.

First claim

The invention claimed is:

1. A cooking appliance comprising:
a cabinet having an interior;
an insert having a port and positioned in the interior and at least partly forming a cooking chamber;
at least one radiant heating element located within the cooking chamber;
an infrared sensor having a sensing field including at least a portion of the cooking chamber;
a low emissive optical element located in the port between the radiant heating element and the infrared sensor; and
at least one flange defining an opening in the insert and located between the optical element and the radiant heating element to prevent direct transmission from the radiant heating element into the optical element.

2. The cooking appliance of claim 1 wherein the optical element comprises at least one of a plastic or glass element with a low emissive coating.

3. The cooking appliance of claim 2 wherein the at least one radiant heating element comprises a quartz heating lamp.

4. The cooking appliance of claim 1 wherein the infrared sensor is located between the cabinet and the insert.

5. The cooking appliance of claim 1 wherein the optical element is located within the port to prevent direct transmission from the radiant heating element onto the optical element.

6. The cooking appliance of claim 1 wherein the insert has a top side and the port is located in the top side.

7. The cooking appliance of claim 6 wherein the at least one radiant heating element comprises two heating elements located near the top side, with the port located between the two heating elements.

8. The cooking appliance of claim 7 wherein the insert further comprises a bottom side and the at least one radiant heating element further comprises at least more heating elements near the bottom side.

9. The cooking appliance of claim 2 wherein the emissivity of the glass element with the low emissive coating is less than 0.03.

10. A cooking appliance comprising:
a cabinet forming an interior and having a cabinet top wall;
an insert having an insert top wall and positioned in the interior forming a cooking chamber;
at least one radiant heating element located within the cooking chamber; and
a sensor assembly provided between the insert top wall and the cabinet top wall;

the sensor assembly comprising an infrared sensor having a sensing field including at least a portion of the cooking chamber;
wherein the insert top wall comprises a sensor port corresponding to the infrared sensor and comprising a low emissive optical element located between the radiant heating element and the infrared sensor.

11. The cooking appliance of claim 10 , wherein the sensor assembly further comprises a camera having a camera field including at least a portion of the cooking chamber.

12. The cooking appliance of claim 11 , wherein the insert top wall further comprises a camera port corresponding to the camera and comprising a low emissive optical element located between the radiant heating element and the camera.

13. The cooking appliance of claim 10 , wherein the at least one radiant heating element comprises two heating elements located near the top wall, with the sensor port located between the two heating elements.

14. The cooking appliance of claim 10 , wherein the insert further comprises a bottom side and the at least one radiant heating element further comprise at least more heating elements near the bottom side.

15. The cooking appliance of claim 10 , wherein the low emissive optical element comprises a low emissive glass having an emissivity of less than 0.03.

16. The cooking appliance of claim 10 , further comprising at least one bumper located within the cooking chamber in front of radiant heating element.

17. The cooking appliance of claim 1 , wherein the port is positioned in a top wall of the insert.

18. The cooking appliance of claim 1 , wherein the flange extends into the cooking chamber.
