Abstract (en)
[origin: ES8701360A1] A radiant heater for cooking appliances with a glass ceramic plate has both bright light-radiating heating elements such as high temperature halogen lamps emitting substantial radiation in the visible range, and also darker glowing radiating elements operable at lower temperatures and radiating emitted light primarily in the infrared region. The bright visible light radiating element and the darker infrared glowing elements are connected in series with one another, whereby the series resistance of the dark or infrared radiator limits initial current loading, and after the radiant elements reach operating temperatures, the infrared radiant element assumes a reduced portion of the total resistance. The visible light and glowing infrared series-connected elements can be interleaved or the visible element can define a boundary for a cooking element. The bright visible and darker glowing elements can be defined by a plurality of elements connectable in parallel and series combinations by a seven-mode switching control, and can be embodied in a variety of configurations in which the visible light and infrared glowing elements are operable or are selectably operable.
