Induction cooking device
View Patent ↗An induction cooking device includes a light-pervious top plate on which a container with liquid contained therein is to be placed. A heating coil resides below the top plate to heat the container. An electrode is located at a portion of a lower surface of the top plate outward of a periphery of the heating coil. A capacitance detection device detects changes in capacitance of the electrode caused by liquid boiled over from the container. The top plate includes a light emitting part by which visible light, applied from a light source placed below the top plate, is transmitted to fulfill light emission. The light emitting part is located at a portion of the top plate between the periphery of the heating coil and the electrode, as viewed from above the top plate.
1. An induction cooking device comprising:
a light-pervious top plate on that is arranged to support a container;
a heating coil below the top plate to heat the container;
an electrode at a portion of a lower surface of the top plate and outward of a periphery of the heating coil; and
a capacitance detection device that detects changes in capacitance of the electrode caused by liquid boiled over from the container,
wherein the top plate includes a light emitting part by which visible light applied from a light source below the top plate is transmitted to fulfill light emission, the light emitting part located at a portion of the top plate between the periphery of the heating coil and the electrode, as viewed from above the top plate.
2. The induction cooking device according to claim 1 , wherein the light emitting part has an annular shape having a center nearly identical to a center of the heating coil, as viewed from above the top plate.
3. The induction cooking device according to claim 1 , wherein the light emitting part has an arc shape having a center nearly identical to a center of the heating coil, as viewed from above the top plate.
4. The induction cooking device according to claim 1 , wherein the light emitting part has an arc shape having a center nearly identical to a center of the heating coil, and located at a portion of the top plate on a front side of the induction cooking device with respect to the heating coil.
5. The induction cooking device according to claim 1 , wherein the light source is variable in its light-application area or light color, based on a heating output of the heating coil, and the light emitting part is located at a portion of the top plate on a front side of the induction cooking device, with respect to the heating coil.
6. The induction cooking device according to claim 1 , wherein the electrode has a plural-band-like shape along the outer periphery of the heating coil.
7. The induction cooking device according to claim 6 , wherein the plurality of electrodes have a nearly identical circumference as viewed from above.
