PURPOSE:To enable measurement of the weight of a material to be heated by causing a door fitted to the front opening part of a heating chamber in an openable and closable to have a function of a pan on which foods are placed. CONSTITUTION:The door 3 provided at the front surface opening part 2 of the heating chamber 1 of an electronic range is opened, and the stopper 9 of a door arm 6 makes contact with a guide roller 7 at a position which becomes substantially horizontal to thereby prevent the door 3 from further opening. A weight detecting part 11 is constituted in such a manner that two leaf springs 14 and 15 are formed into a parallelogram mechanism applied with the well known Roberval mechanism principle, and distortion gages 16 and 17 which vary electric resistance values in proportion to the distortion of the leaf spring 14 are closely attached to said leaf spring 14. |
