ABSTRACT:
In a cooking heater having an automatically opening/closing door, when a lock determination unit detects that transmission of a torque of a driving unit is stopped by detecting an abrupt deceleration, which suggests that an obstacle to the movement of an opening/closing door that is opening/closing is detected, an operation instructing unit operates the opening/closing door in an opposite direction. Further, in the closing operation of the opening/closing door, when an opening/closing door position calculating unit detects the position ahead of a completely closed position at which the opening/closing door is completely closed by the action of an intermediate switch during the closing operation of the opening/closing door, the operating instruction unit lowers the closing speed of the opening/closing door of the operation instruction unit to prevent such a situation that a user's finger or hand is caught in the opening/closing door.
