<p>PROBLEM TO BE SOLVED: To achieve a heating cooker having a function practically enough to control a boiling-overflow.SOLUTION: There is provided a heating cooker including a highly practical function for detecting boiling-overflow. In the heating cooker, when a cooking material 101 boils over a top plate 104 connected to a reference potential 103, the moisture contained in the cooking material 101 functions as a dielectric, a boiling-over detecting means 108 uses a strengthened connection by a capacitive coupling between an electrode 106 and the reference potential 103 because of an increase of a boiling-overflow volume, and detects a capacitance by using a capacitance detecting means 107, and the boiling-over detecting means 108 grasps a change of the capacitance, thereby detecting the boiling-over.</p> |
