ができる０Effects of the Invention As is clear from the above embodiments, according to the present invention, the display means is provided at a position lower than the lower surface of the top plate made of a translucent insulating plate and higher on the upper surface of the heating coil. The area being heated can be directly displayed, and the heating output can be displayed in a manner similar to that of a gas cooker or electric heater. In addition, since the brightness of the display changes according to changes in heating output by the output control means, the heating output can be displayed in a manner similar to that of a gas cooker or electric heater, and the doneness of cooking can be appropriately displayed. be able to. Also,
Since the display range is changed according to the heating output by the output control means, the heating output can be displayed in a sense similar to that of a gas cooker or an electric heater, and the doneness of cooking can be appropriately displayed. In addition, a display means is provided at a position lower than the bottom surface of the top plate made of a translucent insulating plate and higher than the top surface of the heating coil, and a light emitting means is provided inside the main body, so that the area heated by the heating coil can be directly displayed. The heating output can be displayed in a manner similar to that of a gas cooker or electric heater.
