PROBLEM TO BE SOLVED: To provide a door lock control device in a heating cooker capable of allowing the heating cooker to be handled in safety by preventing a door lock from being released by mistake when the door is in a locked state and an inside temperature of the heating cooker is higher than a prescribed value in self-cleaning and the like. SOLUTION: This door lock control device allows electric power to be distributed to a lock detection-thermo circuit portion 6 in an ordinary door lock released state, or even in a door lock state under low inside temperature in a closed state of a thermal switch 8 of the lock detection-thermo circuit portion 6, and a power source line 2 supplies electric power to a driving motor 5 to perform door locking or unlocking operation. In a case of the self-cleaning, the thermal switch 8 is in an opened state as the inside temperature is high, though the door is in the locked state, and a detection switch 7 is located at a door lock side 7a, thus the power source line 2 is cut off. As the power is not distributed to the driving motor 5 even when a driving component is failed, the door lock is not released. COPYRIGHT: (C)2008,JPO&INPIT
