Title: Heating cooking apparatus
Inventor: SAITO TAKESHI
IPC: F24C7/04
Filed: 1990-03-20
Abstract: PURPOSE:To prevent temperature rise of an electric chamber and flow of water and to prevent deterioration in performance and service life of components in the chamber by forming an air layer of a heat shielding plate inclined so that the chamber side is high and the opposite side is low and a heater securing plate above a heater provided at the top of a cooking chamber. CONSTITUTION:A heat shielding plate 8 is mounted while being inclined so that the electric chamber 7 side is high and the opposite side is low thus forming an air layer 9 between the plate 9 and a heater securing plate 3 above a heater 6. If the heater 6 generates heat, the temperature of a cooking chamber 5 is raised to be able to cook, radiated heat is transferred through a heat shielding material 4 and the plate 3 and absorbed to the layer 9. If water is introduced from a discharge port 2, water is fed to the opposite side to the chamber 7 due to inclination of the plate 8. If a heat generating resistor 6a is so wound on a mica 6b as to be rough at the side of the chamber 7 and dense at opposite side to the chamber 7, the quantity of generated heat of the heater 6 at the side of the chamber 7 is reduced proportionally to the number of turns of the resistor 6a to prevent temperature rise of the chamber 7.
