Abstract
One or more cooking elements of a cooking appliance may be controlled during the preheat phase of an oven self-clean cycle to dynamically control a rate of temperature rise to reach a target temperature setpoint at a predetermined time in the oven self-clean cycle.
Claims20
A cooking appliance, comprising:
- a housing including an oven cavity;
- a temperature sensor configured to sense an air temperature within the oven cavity;
- one or more electric cooking elements configured to generate heat within the oven cavity;
- and
- a controller in communication with the temperature sensor and configured to control the one or more electric cooking elements to perform an oven self-clean cycle within the oven cavity, wherein the controller is configured to perform the oven self-clean cycle by regulating the one or more electric cooking elements to maintain the temperature within the oven cavity proximate a self-clean temperature setpoint, and wherein the controller is further configured to perform the oven self-clean cycle by, during a preheat phase of the oven self-clean cycle:
- regulating the one or more electric cooking elements to dynamically control a rate of temperature rise in the oven cavity to reach a first target temperature setpoint that is about 316° C. (about 600° F.) proximate a first predetermined time in the oven self-clean cycle;
- and
- thereafter regulating the one or more electric cooking elements to dynamically control the rate of temperature rise in the oven cavity to reach a second target temperature setpoint that is about 454° C. (about 850° F.) proximate a second predetermined time in the oven self-clean cycle;
- wherein the controller regulates the one or more electric cooking elements to provide a controlled rise time to the self-clean temperature setpoint that is substantially independent of any variance in output power of the one or more electric cooking elements.

A cooking appliance, comprising:
- a housing including a cooking cavity;
- a temperature sensor configured to sense a temperature within the oven cavity;
- one or more cooking elements configured to generate heat within the oven cavity;
- and
- a controller in communication with the temperature sensor and configured to control the one or more cooking elements to perform an oven self-clean cycle within the oven cavity, wherein the controller is configured to perform the oven self-clean cycle by regulating the one or more cooking elements to maintain the temperature within the oven cavity proximate a self-clean temperature setpoint, and wherein the controller is further configured to perform the oven self-clean cycle by, during a preheat phase of the oven self-clean cycle, regulating the one or more cooking elements to dynamically control a rate of temperature rise to reach a target temperature setpoint at a predetermined time in the oven self-clean cycle, wherein the target temperature setpoint is less than the self-clean temperature setpoint.

A method of controlling a cooking appliance, the method comprising:
- sensing a temperature within an oven cavity of a cooking appliance;
- with a controller in communication with the temperature sensor, performing an oven self-clean cycle within the oven cavity by regulating one or more cooking elements that generate heat within the oven cavity to maintain the temperature within the oven cavity proximate a self-clean temperature setpoint;
- and
- with the controller and during a preheat phase of the oven self-clean cycle, regulating the one or more cooking elements to dynamically control a rate of temperature rise to reach a target temperature setpoint at a predetermined time in the oven self-clean cycle, wherein the target temperature setpoint is less than the self-clean temperature setpoint.
