Title: Heating cooker
Inventor: OTA NOBUAKI
IPC: F24C7/02
Filed: 2000-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a heating cooker, capable of uniformly heating an article to be cooked, even when surface temperature distribution of the article varies. SOLUTION: A sensor unit 12 has a plurality of detection fields Ei for detecting temperature Ti for each detection field Ei. Surface temperature of an article to be cooked is herein detected on the basis of averaging the detection temperatures Ti. Since the amount of variations of temperature on the surface temperature reaching finishing temperature is restricted to be within an allowable range, where the finishing temperature is used as a reference, the article is heated uniformly. Further, a choice is made of detection temperature associated with the article, based upon the comparison of the detection temperature Ti with a judgement value, and the selected detection temperatures Ti are averaged. Since factors, other than the article, are prevented from being mixed into a detection result of the surface temperature, a finishing state fitted to the finishing temperature is obtained.
