<p><P>PROBLEM TO BE SOLVED: To provide a heating cooker capable of being cleaned in safety though a capacitance proximity switch is used. <P>SOLUTION: A burner 2 is mounted on a top plate 1 made of an insulating material having heat resistance. A detection electrode 11 is mounted on the under face of the top plate 1, and a mal-operation prevention electrode 12 is mounted around the detection electrode 11. A detection circuit 13 generates a detection output when a finger D approaches the detection electrode 11. A detection circuit 14 generates a detection output when an object approaches the mal-operation prevention electrode 12. A determination circuit 15 invalidates the detection output of the detection circuit 13 when the detection circuit 14 generates the detection output within a prescribed determination period before and after a time when the detection circuit 13 generates the detection output. Further the determination circuit 15 commands ignition and extinction of a burner 2 according to the detection output of the detection circuit 13, when the detection circuit 14 does not generate the detection output within the determination period. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
