Abstract

A method and system are provided or determining a fuel or gas type input into a fuel system or a voltage input into an electrical system of a cooking appliance. For instance, the cooking appliance may be a cooktop appliance or an oven appliance. Particularly, a calibration cycle may be performed in which the heating rate of an object or air at or within the cooking appliance is determined. Based on the determined heating rate, the input may be classified. That is, based on the heating rate, the gas type or input voltage into the cooking appliance may be determined. Further, based on the classified input, the settings of the cooking appliance may be selected for optimal cooking performance.

First claim

What is claimed is:

1. A method for calibrating a cooking appliance, the method comprising:
providing an input to a heating element of the cooking appliance to generate heat at or within the cooking appliance;
receiving a plurality of signals indicative of a temperature of an object or air at or within the cooking appliance;
determining a heating rate of the object or air at or within the cooking appliance for a predetermined operating range based at least in part on the plurality of signals;
classifying the input into one classification of a plurality of classifications based at least in part on the heating rate determined; and
selecting one or more settings of the cooking appliance based at least in part on the classification of the input.

2. The method of claim 1 , wherein classifying the input into one classification of the plurality of classifications based at least in part on the heating rate determined comprises determining whether the heating rate exceeds a threshold.

3. The method of claim 2 , further comprising:
determining a heating system type of the cooking appliance, wherein the heating system type is one of an electrical system and a fuel system; and
setting the threshold based at least in part on the heating system type determined.

4. The method of claim 3 , wherein the plurality of signals indicative of the temperature of the object or air at or within the cooking appliance are received from a sensor, and wherein during setting the threshold, the threshold is set based at least in part on a location of the sensor.

5. The method of claim 1 , wherein classifying the input into one classification of the plurality of classifications based at least in part on the heating rate determined comprises comparing the heating rate to one or more thresholds.

6. The method of claim 1 , wherein the heating rate is indicative of a change in the temperature of the object or air at or within the cooking appliance over time for the predetermined operating range.

7. The method of claim 1 , wherein the input is a gas input and the plurality of classifications are representative of gas types.

8. The method of claim 1 , wherein the input is a voltage input and the plurality of classifications are representative of line voltage values.

9. The method of claim 1 , further comprising:
calculating an average heating rate of the heating rate for the predetermined operating range, and wherein during classifying, the input is classified into one classification of the plurality of classifications based at least in part on the average heating rate for the predetermined operating range.

10. The method of claim 1 , further comprising:
calculating a derivate of the heating rate, and wherein during classifying, the input is classified into one classification of the plurality of classifications based at least in part on the derivative of the heating rate.

11. The method of claim 1 , further comprising:
calculating an integral of the heating rate, and wherein during classifying, the input is classified into one classification of the plurality of classifications based at least in part on the integral of the heating rate.

12. The method of claim 1 , wherein classifying the input is classified into one classification of the plurality of classifications comprises comparing a slope of the heating rate for the predetermined operating range to one or more thresholds.

13. The method of claim 1 , wherein the input is a gas input, and wherein classifying the input into one classification of the plurality of classifications based at least in part on the heating rate determined comprises determining whether the heating rate exceeds an error threshold, and wherein when the heating rate exceeds the error threshold, the method further comprises:
communicating an alert that the heating rate exceeds the error threshold.
