HEATING COOKER

PROBLEM TO BE SOLVED: To provide a device capable of determining the weight of a heating object based on the change in weight by loading the heating object on an opening/closing door for putting/taking out the heating object into/from a heating chamber. SOLUTION: The opening/closing door 11 performs smooth opening and closing operations through an arm member 15 which slides on a roller 14 provided on a hinge member 13. One end of the arm member 15 is hooked on a pin 16 provided on the inside of the opening/closing door 11, and the other end is connected to a main body bottom by a tension spring 17. A means 18 for detecting a weight change is provided on the back side of a wall face of the heating chamber 10 opposing the opening/closing door 11, with its one end supported and fixed on the wall face of the heating chamber 10. A gap is provided between the other end and the wall face of the heating chamber 10. Weight is applied to an abutting part 15a of the arm member 15 upon opening of the opening/closing door 11, and the weight of the heating object is determined based on the amount of change of the weight. Based on the determined weight value, a heating means included in the heating cooker is controlled, and the heating object can be ideally heated. COPYRIGHT: (C)2007,JPO&INPIT
