ABSTRACT:
A microwave oven having a cavity for receiving a food item to be cooked, primarily meat items, a magnetron for delivering microwave power to the cavity, and a forced hot air system, including a fan and an electrical resistance heating element which are both disposed in a compartment separated from the cavity by a dividing panel. The oven has a first thermistor for monitoring air temperature drawn from the oven cavity after a predetermined time, between eight and fifteen minutes, dependent upon the nature of the food item to be cooked. When the predetermined time is reached, a microprocessor determines the remaining cooking time to complete cooking by referring to an internal program that relates to the particular food item to be cooked. A second thermistor monitors temperature near the heating element and, through the microprocessor, controls the heating element. The microprocessor thus determines a decreasing maximum air temperature curve over the remaining cooking time which is to be executed from the predetermined time to the end of cooking by referring to an internal program for sensed temperature control, again relating to the particular food item to be cooked.
