Abstract

PURPOSE:To enhance the energy efficiency by making a reflex plate installed below a lamp heater in a form combining two parabolic mirrors. CONSTITUTION:A cooking apparatus according to the invention includes halogen lamps 2 arranged parallelly in a casing with its uppersurface opened, a reflex plate 3 arranged below this halogen lamp 2, a heat insulation vessel 4 arranged so as to bear this reflex plate 3 from below, and a plate 5 of heat resistant glass fitted so as to cover the uppersurface opening of the mentioned casing. The reflex plate 3 is made in the form with two parabolic mirrors combined. This enables all infrared rays emitted from the lamp heater to be irradiated toward the plate. This enhances the energy efficiency.
