Abstract

A cooking appliance for cooking a foodstuff over a period of time including a shell having a heating cavity and a heating element to heat the heating cavity. A container is removably positionable within the heating cavity and includes a food cavity for receiving the foodstuff. A temperature probe is removably insertable into the foodstuff and a controller is mounted to the shell. The controller controls operation of the cooking appliance in a probe mode wherein the temperature probe is inserted into the foodstuff and transmits foodstuff temperatures to the controller for controlling the heating of the foodstuff, a program mode wherein the controller actuates the heating element to heat the container at a temperature for a selected amount of time and subsequently at a lower temperature and a manual mode wherein the controller actuates the heating element to heat the container at a selected temperature.

Claims

1. A cooking appliance for cooking a foodstuff over a period of time, the cooking appliance comprising:

a shell including an external wrap and a liner, an air gap being defined between the external wrap and the liner, the external wrap including an exposed surface and a controller depression;

a heating element secured to the liner; and

a control panel including a display face for mounting a controller to the shell, the control panel being mounted in the controller depression such that the display face is positioned one of flush with the exposed surface of the shell and inwardly toward the liner relative to the exposed surface of the shell, the control panel pivotably mounted to the shell and being sealed to generally prevent fluids from coming into contact with the controller, which is located within the control panel.

2. The cooking appliance of claim 1 wherein the controller depression is comprised of a shelf and a controller hole in the external wrap.

3. The cooking appliance of claim 2 wherein the control panel includes a display panel, a hinge panel and a hinge mounting the display panel to the hinge panel, the hinge panel including a first mounting hole therein and the display panel including a second mounting hole and a clearance hole therein, the first and second mounting holes having a smaller diameter than the clearance hole.

4. The cooking appliance of claim 3 wherein the hinge panel includes a first face and a second face and the display panel includes an internal face and the display face, a portion of the internal face and the first face in facing engagement with the shelf in an assembled configuration.

5. The cooking appliance of claim 4 wherein the hinge panel is pivoted about the hinge such that the second face is in facing engagement with the internal face in a mounting position, the clearance hole aligning with the first mounting hole in the mounting position.

6. The cooking appliance of claim 5 further comprising:

a first fastener extending through the clearance hole and the first mounting hole in the assembled configuration; and

a second fastener extending through the second mounting hole in the assembled configuration;

the first and second fasteners mounting the control panel to the shell.

7. The cooking appliance of claim 3 wherein the hinge is comprised of a living hinge.

8. The cooking appliance of claim 7 wherein the control panel is constructed of a polymeric material.

9. The cooking appliance of claim 1 wherein the control panel includes a display panel, a hinge panel, a hinge mounting the display panel to the hinge panel and a cover removably mounted to an internal face of the display panel, the controller mounted between the display panel and the cover.

10. The cooking appliance of claim 9 further comprising:

an electrical cord in communication with the controller, the cover including a cord hole, the electrical cord extending through the cord hole, a sealant sealing the cord hole with the electrical cord therein in an assembled configuration to generally prevent fluids from coming into contact with the controller mounted within the control panel.

11. A cooking appliance for cooking a foodstuff over a period of time, the cooking appliance comprising:

a shell including an external wrap and a liner, an air gap being defined between the external wrap and the liner, the external wrap including a controller depression;

a heating element secured to the liner;

a controller mounted to the shell, the controller actuating the heating element to heat the liner; and

a control panel including a living hinge, the control panel pivotably mounting the controller in the controller depression.

12. The cooking appliance of claim 11 wherein the control panel includes a hinge panel and a display panel, the living hinge securing the hinge panel to the display panel.

13. The cooking appliance of claim 12 wherein the controller depression includes a shelf and a controller hole, a peripheral portion of the display panel mounted proximate the shelf in an assembled configuration.

14. The cooking appliance of claim 12 wherein the hinge panel includes a first mounting hole therein and the display panel includes a clearance hole therein, the first mounting hole and the clearance hole being aligned in a mounting position.

15. The cooking appliance of claim 14 wherein the control panel is mounted to the shell by a first fastener that extends through the first mounting hole and the clearance hole, the display panel being pivotable relative to the hinge panel and shell.

16. The cooking appliance of claim 15 wherein the hinge panel includes a second mounting hole therein, a second fastener extending through the second mounting hole to mount the control panel to the shell in an assembled configuration.

17. The cooking appliance of claim 11 wherein the controller is comprised of a programmable controller.
