PROBLEM TO BE SOLVED: To prevent damaging deliciousness by excessive heating.SOLUTION: A heat-insulating device includes: first heating control means (microcomputer) for controlling heating means so as to let a detection value of temperature detection means keep an adjustment temperature Tk of a lower limit; second heating control means (microcomputer) for controlling the heating means so as to let a detection value of the temperature detection means rise to a heating target temperature Tt of an upper limit; time-measuring means for measuring a time when a temperature is below a reference temperature Tc higher than the adjustment temperature Tk and lower than the heating target temperature Tt; and heat insulation control means (microcomputer) for adjusting to the adjustment temperature Tk and raising a temperature to the heating target temperature Tt when a measured time with the time-measuring means becomes a temperature rise starting time th. |
