Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To execute highly accurate automatic cooking by calibrating a weight measuring means based on a weight measured by a weight measuring means when an article detecting means decides that no article is present thereby measuring the weight accurately. SOLUTION: A fixed electrode plate 16 and a movable electrode plate 17 are disposed oppositely to form a capacitor and a transmission circuit 18 having a transmission frequency dependent on the capacity variation of the capacitor is provided. When an article to be heated is mounted on a turntable 14, the movable electrode plate 17 descends while resisting against urging force of a resilient body. Consequently, the separation distance between the fixed electrode plate 16 and the movable electrode plate 17 is varied to cause variation in the capacity of the capacitor and thereby weight sensor 12 can measure the weight of the article along with the turntable 14. Weight of the article can be measured accurately based on the difference of the measured weight and the weight of the turntable 14, and the like, when the article is not mounted previously measured and stored in a nonvolatile memory.
