Abstract

An adjustable camera assembly mounted within a door of an oven appliance includes a vertical guide rail and a camera movably mounted to the guide rail. A drive mechanism, such as a lead screw driven by a stepper motor, is mechanically coupled to the camera for moving the camera along the guide rail. A controller is coupled to a user interface for obtaining a rack position where food is located. Based on the rack position, the controller determines a viewing position where the camera is placed to achieve a desired view of the food and operates the drive mechanism to position the camera in the viewing position.

First claim

What is claimed is:

1. A camera assembly for an oven appliance, the oven appliance comprising a cooking chamber and one or more racks positioned within the cooking chamber, the camera assembly comprising:
a guide rail;
a camera movably mounted to the guide rail;
a drive mechanism mechanically coupled to the camera for moving the camera along the guide rail; and
a controller in operative communication with the drive mechanism, the controller being configured for:
obtaining a rack position where food is located or will be located;
determining, based on the rack position, a viewing position where the camera is placed to achieve a desired view of the food; and
operating the drive mechanism to position the camera in the viewing position.

2. The camera assembly of claim 1 , wherein obtaining the rack position comprises:
receiving a food type of the food being cooked; and
determining the rack position based on the food type.

3. The camera assembly of claim 2 , wherein the controller is further configured for:
communicating the rack position to a user of the oven appliance.

4. The camera assembly of claim 1 , wherein the oven appliance further comprises:
a user interface for receiving user inputs and communicating rack positions to a user of the oven appliance.

5. The camera assembly of claim 4 , wherein obtaining the rack position comprises:
displaying a query regarding the rack position on the user interface; and
receiving a user input regarding the rack position in response to the query.

6. The camera assembly of claim 4 , wherein the user interface comprises input buttons for selecting the rack position.

7. The camera assembly of claim 4 , wherein the user interface comprises directional inputs for facilitating manual adjustment of the viewing position of the camera.

8. The camera assembly of claim 1 , wherein the controller is configured for moving the camera to a plurality of discrete viewing positions.

9. The camera assembly of claim 1 , wherein the plurality of discrete viewing positions comprises six viewing positions spaced apart along a vertical direction.

10. The camera assembly of claim 1 , wherein the viewing position of the camera is above the rack position along the vertical direction.

11. The camera assembly of claim 1 , wherein the camera is positioned at a fixed angle relative to a transverse direction.

12. The camera assembly of claim 1 , wherein the oven appliance comprises a door rotatably mounted to a cabinet for providing selective access to the cooking chamber, the door comprising:
an inner door panel; and
an outer door panel spaced apart from the inner door panel by an air gap, the camera assembly being positioned within the air gap.

13. The camera assembly of claim 1 , wherein the drive mechanism comprises:
a lead screw mechanically coupled to the camera and extending substantially parallel to the guide rail; and
a drive motor for rotating the lead screw to move the camera along the guide rail.

14. The camera assembly of claim 13 , further comprising:
a camera housing extending between a first end and a second end along the lateral direction, wherein the guide rail is slidably coupled to the first end and the lead screw is operably coupled to the second end.

15. A method of operating a camera assembly of an oven appliance, the camera assembly comprising a camera slidably mounted to a guide rail and a drive mechanism for selectively moving the camera along the guide rail, the method comprising:
obtaining a rack position where food is located or will be located;
determining, based on the rack position, a viewing position where the camera is placed to achieve a desired view of the food; and
operating the drive mechanism to position the camera in the viewing position.

16. The method of claim 15 , wherein obtaining the rack position comprises:
receiving a food type of the food being cooked; and
determining the rack position based on the food type.

17. The method of claim 16 , further comprising:
communicating the rack position to a user of the oven appliance.

18. The method of claim 15 , wherein obtaining the rack position comprises:
displaying a query regarding the rack position on a user interface; and
receiving a user input regarding the rack position in response to the query.

19. The method of claim 15 , further comprising:
receiving the rack position from input buttons positioned on a user interface.

20. The method of claim 15 , further comprising:
receiving manual adjustments of the viewing position from directional inputs on a user interface.
