Abstract

In one aspect, a cooktop heating system that include a first cooktop heating element, a second cooktop heating element, and an interface device. The system also includes a controller for selectively associating the interface device with any one or both of the first cooktop heating element and the second cooktop heating element. In another aspect, the system includes at least one cooktop heating element, a potentiometer, and controller arrangement operatively connected between the potentiometer and the at least one cooktop heating element to determine heating of the at least one cooktop heating element responsive to the input provided by the potentiometer and control power provision to the at least one cooktop heating element responsive to the determination.

Claims

a fourth cooktop heating element;

a user interface device for receiving a heating element setting from a user; and

a controller for selectively associating the user interface device with any one or more of the first cooktop heating element, the second cooktop heating element, the third cooktop heating element, and the fourth cooktop heating element.

2. A system as set forth in claim 1, wherein a selective association of the interface device with any one or more of the first cooktop heating element, the second cooktop heating element, the third cooktop heating element, and the fourth cooktop heating element is based on an input from a user.

3. A system as set forth in claim 1, further including means for sensing the presence of a cooking receptacle at the first cooktop heating element, wherein a power output to the first cooktop heating element is provided only when a cooking receptacle is present at the first cooktop heating element.

4. A system as set forth in claim 1, further including means for controlling an auxiliary device.

5. A system as set forth in claim 1, wherein the controller includes a processor.

6. A system as set forth in claim 5, wherein the controller is programmed to obtain a heating element power setting from the user interface device and select a heating element power level that corresponds to the heating element power setting from one of a first heating profile and a second heating profile.

7. A system as set forth in claim 6, wherein a duty cycle of power output to one or both of the first cooktop heating element and the second cooktop heating element corresponds to the heating element power level.

8. A system as set forth in claim 6, further including a temperature sensor for measuring a temperature of one or both of the first cooktop heating element and the second cooktop heating element, wherein a power output to one or both of the first cooktop heating element and the second cooktop heating element is controlled according to a temperature measurement of the temperature sensor.

9. A system as set forth in claim 1, further including an additional user interface device, wherein the controller can selectively associate the additional user interface device with any one or more of the first cooktop heating element, the second cooktop heating element, the third cooktop heating element, and the fourth cooktop heating element.

10. A system as set forth in claim 1, wherein the user interface device includes a potentiometer.

11. A system as set forth in claim 10, further including an additional user interface device including an additional potentiometer, wherein the controller can selectively associate the additional user interface device with any one or more of the first cooktop heating element, the second cooktop heating element, the third cooktop heating element, and the fourth cooktop heating element.

12. A system as set forth in claim 1, wherein the controller can selectively associate the user interface device with any two or more of the first cooktop heating element, the second cooktop heating element, the third cooktop heating element, and the fourth cooktop heating element.

13. A system as set forth in claim 1, wherein the controller can selectively associate the user interface device with any three or more of the first cooktop heating element, the second cooktop heating element, the third cooktop heating element, and the fourth cooktop heating element.

14. A system as set forth in claim 1, further including:

a fifth cooktop heating element; and

a sixth cooktop heating element, wherein the controller can selectively associate the user interface device with any one or more of the first cooktop heating element, the second cooktop heating element, the third cooktop heating element, the fourth cooktop heating element, the fifth cooktop heating element, and the sixth cooktop heating element.

15. A system as set forth in claim 14, further including an additional user interface device, wherein the controller can selectively associate the additional user interface device with any one or more of the first cooktop heating element, the second cooktop heating element, the third cooktop heating element, the fourth cooktop heating element the fifth cooktop heating element, and the sixth cooktop heating element.

16. A system as set forth in claim 14, wherein the controller can selectively associate the user interface device with any two or more of the first cooktop heating element, the second cooktop heating element, the third cooktop heating element, the fourth cooktop heating element, the fifth cooktop heating element, and the sixth cooktop heating element.

17.
