Abstract

A method of closed loop cooking on an appliance includes monitoring, by a controller, a temperature measurement from a sensor indicative of a cooking temperature during a cooking operation. Comparing, by the controller, the temperature measurement to a set temperature of the cooking operation. Determining, by the controller, a heating event defined by the temperature measurement. Adjusting, by the controller, a cycle period time for a heating element. The cycle period time is associated with the heating event.

First claim

What is claimed is:

1 . A method of closed loop cooking on an appliance, comprising:
monitoring, by a controller, a temperature measurement from a sensor indicative of a cooking temperature during a cooking operation; comparing, by the controller, the temperature measurement to a set temperature of the cooking operation; determining, by the controller, a heating event defined by the temperature measurement; and adjusting, by the controller, a cycle period time for a heating element, the cycle period time associated with the heating event.

2 . The method of claim 1 , wherein the cycle period time is selected from a lookup table stored in a memory of the controller.

3 . The method of claim 1 , further comprising identifying, by the controller, a cooking event associated with the heating event.

4 . The method of claim 3 , wherein the cooking event comprises one or both of adding a food item to a cooking utensil, and flipping the food item in the cooking utensil.

5 . The method of claim 1 , wherein the heating event comprises a temperature decrease.

6 . The method of claim 1 , wherein the sensor comprises a temperature sensor positioned one or more of within a cooking utensil, within a heating assembly of the appliance, and proximate the cooking utensil.

7 . The method of claim 1 , further comprising calculating, by the controller, recovery period parameters after the heating event for the temperature measurement to attain the set temperature, the recovery period parameters comprising one or more of a rate of recovery, a current power level of the appliance, a controller gain, the temperature measurement, a temperature error when the recovery period starts, a quantity of food, a type of food, and a material of a cooking utensil, the rate of recovery, calculated using the difference in the temperature measurement over time.

8 . The method of claim 7 , wherein the cycle period time is selected based upon the temperature error and rate of recovery.

9 . The method of claim 7 , wherein the cycle period time is selected based upon a temperature measurement after the heating event.

10 . The method of claim 1 , wherein the appliance is one of a cooktop appliance, a range appliance, or an oven appliance.

11 . The method of claim 1 , wherein the temperature measurement from the sensor is indicative of a temperature of a cooking utensil heated by the heating element.

12 . A method of cycle period adjustment on an appliance, comprising:
monitoring, by a controller, a temperature measurement from a sensor indicative of a cooking temperature during a cooking operation; comparing, by the controller, the temperature measurement to a set temperature of the cooking operation; determining, by the controller, a heating event defined by the temperature measurement; identifying, by the controller, a cooking event associated with the heating event; calculating, by the controller, recovery period parameters after the heating event for the temperature measurement to attain the set temperature, the recovery period parameters comprising one or more of a rate of recovery, a current power level of the appliance, controller gains, the temperature measurement, a temperature error when the recovery period starts, a quantity of food, a type of food, and a material of a cooking utensil, the rate of recovery, calculated using the difference in the temperature measurement over time; and adjusting, by the controller, a cycle period time for a heating element, the cycle period time associated with the calculated recovery period parameters.

13 . The method of claim 12 , wherein the cycle period time is selected from a lookup table stored in a memory of the controller.

14 . The method of claim 12 , wherein the cooking event comprises one or both of adding a food item to a cooking utensil, and flipping the food item in the cooking utensil.

15 . The method of claim 12 , wherein the heating event comprises a temperature decrease.

16 . The method of claim 12 , wherein the sensor comprises a temperature sensor positioned one or more of within a cooking utensil, within a heating assembly of the appliance, and proximate the cooking utensil.

17 . The method of claim 16 , wherein the cycle period time is selected based upon the temperature error and rate of recovery.

18 . The method of claim 12 , wherein the cycle period time is selected based upon a temperature measurement after the heating event.

19 . The method of claim 12 , wherein the temperature measurement from the sensor is indicative of a temperature of a cooking utensil heated by the heating element.

20 . The method of claim 12 , wherein the appliance is one of a cooktop appliance, a range appliance, or an oven appliance.
