Claims19
A method for controlling an electric cooking oven including a first heating element positioned in an upper area of an oven cavity and a second heating element positioned in a lower area of the oven cavity, the method comprising the steps of:
- energizing the first and second heating elements during a first preheating phase in which an oven temperature substantially rises from a first temperature to reach a predetermined set point temperature;
- releasing an overall nominal average power from the first and second heating elements combined;
- maintaining during the first, preheating phase, a ratio of a nominal average power, defined as a maximum deliverable power of the first heating element times a duty cycle of the first heating element, released by the first heating element to a nominal average power, defined as a maximum deliverable Dower of the second heating element times a duty cycle of the second heating element, released by the second heating element between 1.1 and 1.3 and the overall nominal average power between 1670 and 1900 W.
A method for controlling an electric cooking oven including a first heating element positioned in an upper area of an oven cavity and a second heating element positioned in a lower area of the oven cavity, the method comprising the steps of:
- measuring a total electrical power absorbed by the oven utilizing an oven temperature acquisition system;
- automatically detecting a presence or absence of food inside the oven based on the total electrical power absorbed, wherein when the presence of food is detected, a first, preheating phase is implemented including the step of:
- energizing the first and second heating elements during a first preheating phase in which an oven temperature substantially rises from a first temperature to reach a predetermined set point temperature;
- releasing an overall nominal average power from the first and second heating elements combined;
- maintaining during the first, preheating phase, a ratio of a nominal average power, defined as a maximum deliverable power of the first heating element times a duty cycle of the first heating element, released by the first heating element to a nominal average power, defined as a maximum deliverable power of the second heating element times a duty cycle of the second heating element, released by the second heating element between 1.1 and 1.3 and the overall nominal average power between 1670 and 1900 W,
- wherein when the absence of food is detected, a second, preheating phase is implemented including the step of:
- operating the first and second heating elements such that the predetermined set point temperature is reached in a shortest amount of time possible given a maximum power deliverable by the first and second heating elements.
