Document Type and Number:
Japanese Patent JP2849546
Kind Code:
B2
Abstract:
During operation of a microwave oven, steps are taken to determine whether the oven is being operated in the absence of food therein and to shut down the oven if that state is found to exist. Initially, a high frequency detector disposed in the cooking chamber absorbs high frequency and produces heat in proportion to the absorbed high frequency. A temperature sensor senses the temperature of that produced heat and generates an output signal as a function thereof. After a predetermined time period, that output signal is compared to a reference value which represents a temperature expected to occur in the event that the oven is being operated in the absence of food. If it is determined from that comparison that no food is present in the oven, the oven is deactivated and an alarm is activated.
