Abstract
Official abstract text for this publication.
The cooking device includes a top plate on which a container is to be placed, heating devices provided below the top plate, electrodes provided in a lower face of the top plate and including a boiling-over detection parts placed near an outer periphery of a portion of the top plate positioned above the heating devices, contact parts for supplying an AC current to the boiling-over detection parts, and contact parts for connecting the contact parts and one-side ends of the boiling-over detection parts to each other, respectively, an electrode-use capacitance detection device for detecting changes in capacitance of the boiling-over detection parts, and a control device for controlling the heating devices based on changes in capacitance detected by the electrode-use capacitance detection device. The contact parts are provided at positions farther from the heating devices and on a more front side of the cooking device than the boiling-over detection parts, and the connection parts run through on the outer peripheral side of the boiling-over detection parts.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cooking device for heating a container comprising: a ceramic top plate on which the container is to be placed; a heating device provided below the top plate and serving for heating the container; a conductor electrode provided in a lower face of the top plate, the conductor electrode including: an arc-shaped belt-like boiling-over detection part placed near and extending continuously along an outer periphery of a portion of the top plate, said p…
