Abstract

An intelligent cooking system includes cooking implements such as saucepans, stockpots, etc., having a temperature sensor for sensing either the temperature of the cooking implement or any contents located therein. A plurality of heating surfaces each have a surface for supporting and transferring heat to the cooking implements. A temperature control knob for setting a desired cooking temperature and a timer control knob are also provided. A controller is operably connected to the temperature control knob, the timer control knob, the heating surface, and the temperature sensor via infrared for controlling the temperature of the heating surface based on temperature signals received from the sensor and the desired cooking temperature. Each of the cooking implements and each of the heating surfaces are distinguished by the controller so as to track the movement of any of the cooking implements between one or more of the heating surfaces. As a cooking implement is transferred from one heating surface to another, the desired temperature associated with the heating surface is transferred along with the cooking implement to control the new heating surface. When a desired cooking time interval is set, the remaining portion of the desired cooking time interval can be transferred along with the desired cooking temperature.

Claims

1. An intelligent food cooking system comprising:

at least one cooking implement having a temperature sensor;

a plurality of heating surfaces for supporting and transferring heat to the cooking implement;

a proximity sensor associated with each heating surface;

a device for setting a desired cooking temperature; and

controller means operably connected to the temperature sensor, each temperature setting device, each proximity sensor, and each heating surface for controlling the temperature of each heating surface based on temperature signals received from the sensor and the desired cooking temperature and on the presence or absence of the at least one cooking implement on one or more of the heating surfaces as sensed by the proximity sensors.

2. An intelligent food cooking system according to claim 1 wherein the at least one cooking implement comprises a plurality of cooking implements, each cooking implement having a separate temperature sensor.

3. An intelligent food cooking system according to claim 1 wherein the controller includes means for distinguishing between each of the cooking implements and means for distinguishing between each of the proximity sensors such that the movement of any of the plurality of cooking implements between one or more of the heating surfaces can be tracked by the controller.

4. An intelligent food cooking system according to claim 3 and further comprising a preset cooking program associated with at least one of the cooking implements stationed on one of the heating surfaces, the preset cooking program being operably connected to the controller, so that the preset program follows the movement of the at least one cooking element to another of the heating surfaces.

5. An intelligent food cooking system according to claim 4 wherein the preset cooking program includes a timer setting for activating or deactivating the associated heating surface after a desired time period.

6. An intelligent food cooking system according to claim 5 wherein the preset program includes two different temperature settings for the desired time period.

7. An intelligent food cooking system according to claim 1 and further comprising a preset cooking program associated with at least one of the cooking implements stationed on one of the heating surfaces, the preset cooking program being operably connected to the controller, such that the preset program follows the movement of the at least one cooking element to another of the heating surfaces.

8. An intelligent food cooking system according to claim 4 and further comprising a remote control for entering the preset program.

9. An intelligent food cooking system according to claim 1 wherein the device for setting a desired cooking temperature comprises a remote control.

10. An intelligent food cooking system according to claim 1 wherein each of the plurality of heating surfaces comprises a glass-ceramic insert.

11. An intelligent food cooking system according to claim 10 wherein the glass-ceramic insert includes a plurality of radially extending grooves formed in the top surface thereof.

12. An intelligent food cooking system according to claim 1 wherein the controller includes a receiver and the temperature sensor includes a transmitter for sending signals indicative of current temperature to the receiver.

13. A method for controlled cooking of food comprising:

providing a plurality of heating surfaces;

placing at least one cooking implement on one of the plurality of heating surfaces;

setting a desired cooking temperature for any contents in the cooking implement;

measuring the temperature of at least one of the cooking implement and the contents;

controlling the temperature of the one heating surface to maintain the desired temperature;

moving the cooking implement from the one heating surface to a second heating surface of the plurality of heating surfaces;

tracking the movement of the implement from the one heating surface to the second heating surface; and

controlling the temperature of the second heating surface to maintain the desired temperature.

14. A method according to claim 13 wherein the step of providing at least one cooking implement includes providing a plurality of cooking implements;

and further comprising the steps of distinguishing between each of the cooking implements and distinguishing between each of the heating surfaces to track the movement of any of the plurality of cooking implements between one or more of the heating surfaces.

15. A method according to claim 13 and further comprising the step of setting a desired cooking time interval and wherein the step of transferring includes transferring at least a remaining portion of the desired cooking time interval.

16. A method according to claim 13 wherein the step of providing the plurality of heating surfaces includes providing a glass ceramic insert for each of the heating surfaces.

17. A method according to claim 16 wherein each glass-ceramic insert includes a plurality of radially extending grooves formed in the top surface thereof.

18. A method for controlled cooking of food comprising:

providing a plurality of heating surfaces;

placing a plurality of cooking implements on the plurality of heating surfaces;

setting one or more desired cooking temperatures for any contents in each of the cooking implements;

measuring one of the temperature of each of the cooking implements and the temperature of the contents in each of the cooking implements;

controlling the temperature of the heating surfaces to maintain the desired temperatures;

distinguishing between each of the cooking implements; and

distinguishing between each of the heating surfaces to track movement of any of the plurality of cooking implements between one or more of the heating surfaces.
