<p>PROBLEM TO BE SOLVED: To provide a cooking device that does not show any accidental inconvenience of non-availability in operation when a desorption current of a flow rate control valve is decreased.SOLUTION: This invention relates to a cooking device in which if an opened state of a flow rate control valve 3 other than one flow rate control valve 27 is kept, one flow rate control valve 27 is closed and combustion detection means 51 does not detect a stopped combustion when the flow rate control valve 27 is closed, it is judged that one flow rate control valve 27 is in a troubled state, a current RI for confirming desorption current set to a lower value than an adsorption current KI is electrically conducted to one flow rate control valve 27 before electric conduction of adsorption current KI is shut off after the opened state is kept and in turn in the case that the combustion detection means 51 does not detect any stopped combustion, it is judged that one flow rate control valve 27 keeps excessively small desorption current and then the cooking device performs a processing for excessively small desorption current state.</p> |
