Abstract
An oven for cooking a food product that is exactly controlled for various cooking parameters, including cooking time, temperature, cooking elements used and cooking element duty cycle. Top and bottom cooking elements are provided in the oven. Temperature sensors are placed between each cooking element and the food product. The oven temperature is sensed when the food product is placed in the oven. The type of food product placed in the oven is indicated by the baker a control panel. Previously stored data indicates the cooking parameters to provide the best possible food product. The microprocessor controls the cooking elements to cook the food product according to the cooking parameters. As the correct cooking temperature is approached, the duty cycle of the cooking elements is lowered to ensure that the proper temperature is not exceeded. Once the correct cooking temperature is reached, the cooking elements operate at a predetermined duty cycle for the remaining cooking time. An indication is provided that the food product is done and the food product is removed from the oven. Openings are provided in the oven to permit heat to escape and to permit the food product to be removed from the front or back of the oven.
