Heating/cooking equipment

摘要

There is provided a heating/cooking equipment capable of accurately determining boiling over. The heating/cooking equipment includes: a top plate (104) connected to a reference potential; a heating unit (105) configured to heat an object to be heated placed on the top plate; an electrode (106) arranged under the top plate; a capacitance detecting unit (107) configured to detect the electrostatic capacitance of the electrode; a boiling over detecting unit (108) configured to detect whether or not a material to be cooked in the object to be heated has boiled over on the top plate, based on a value of the electrostatic capacitance detected by the capacitance detecting unit; and a control unit (109) configured to control the heating operation of the heating unit based on a boiling over detection result from the boiling over detecting unit. The capacitance detecting unit (107) detects a change in the electrostatic capacitance of the electrode by exploiting capacitive coupling between the electrode and the reference potential which is enhanced by increase in a boiled over amount of the material to be cooked with moisture contained in the material to be cooked functioning as a dielectric when the material to be cooked boils over on the top plate.
