Abstract
An automatic heating apparatus comprising a sensor such as a humidity sensor or a gas sensor which senses water vapor, alcohol, CO.sub.2 gas or the like emitted from a foodstuff being heated for automatically completing cooking. A microcomputer, which is a controller, monitors variations in the quantity of emitted water vapor, CO.sub.2 gas, alcohol or the like with respect to time and, on the basis of the result of this monitoring, decides automatically whether the foodstuff is covered or not with a plastic sheet or is enclosed or not in a lidded container. According to the result of this decision, the heating data including the heating duration and heating output are modified so as to attain optimum heating regardless of the presence or absence of the cover or regardless of the volume of the lidded container.
