APPARATUS AND METHOD FOR CONTROLLING COOLING TIME OF MICROWAVE OVEN

摘要

An apparatus and method for controlling cooling time of a microwave oven tha t is capable of controlling an initial cooling time, which is given to secure stable operational characteristics of a sensor, when sensor-based automatic cooking is performe d, thereby reducing total cooking time. The cooling time control method includes determining whether sensor-based automatic cooking is performed, when the sensor-based automatic cooking is performed, operating a cooling fan to perform cooling operation such that a sensor is cooled, sensing an output value of the sensor, when the cooling operation is performed, to calculate a change of the sensor output value, and comparing the calculated change of th e sensor output value with a predetermined reference value, and, when the change of the sens or output value exceeds the predetermined reference value, controlling cooling time based on the change of the sensor output value.
