<P>PROBLEM TO BE SOLVED: To provide a heating cooker configured such that a heater can be easily mounted and dismounted from a heating chamber or exchanged, thereby, the heating chamber is easily cleaned, and that when the heater is detected not to be properly mounted inside the heating chamber, abnormal conditions are sensed to notify a user, which enhances safeness and reliability of the cooker. <P>SOLUTION: The heating cooker includes: heaters 20a, 20b, which are detachably mounted inside a heating chamber 10 and are formed of electrically closed conductors; a resonance circuit unit comprising coils 30a, 30b disposed outside the heating chamber 10 and a resonance capacitor connected to the coils; an inverter circuit supplying a high-frequency current having a drive frequency to the resonance circuit unit; a magnetic material disposed to interlink with the heaters; a drive voltage detecting unit for detecting a drive voltage applied to both ends of the resonance circuit unit; a drive current detecting unit for detecting a drive current flowing in the resonance circuit unit; and a load condition determining unit for determining a load condition of the heaters on the basis of the detected drive voltage and the drive current. <P>COPYRIGHT: (C)2012,JPO&INPIT |
