摘要： PURPOSE:To treat a large proportion of smoke with a high efficiency for purifying sooty smoke by a method wherein a fan draws out smoke produced from food under heating and the smoke is made to undergo oxidation decomposition with the aid of an oxidation catalyst heated by the heat from heaters. CONSTITUTION:The top plate 2 of a cooking chamber 1 has air discharge holes 3 opened at the rear part by punching as vents opening into an air discharge passageway 5 formed in a space between the top plate 2 and an insulator 4. A porous material 6 of inorganic fiber in loose form, which carries an oxidation catalyst in a dispersed state, is fixed to the air discharge passageway 5. By the suction of a fan 11, the smoke produced from food 7 under heating is drawn into the air discharge holes 3, passed through the porous inorganic fiber material 6, and discharged through a discharge outlet 9. During this passage, the sooty or odoriferous component of the discharged air undergoes decomposition by virtue of the catalyst, which is heated by upper heaters 8, and is then eliminated. When the temperature of the porous inorganic fiber material 6 falls, for example, while lower heaters 10 are working, the porous inorganic fiber material 6 serves as a filter for the smoke so that a fairly large proportion of smoke is adsorbed for a time and burnt out when the temperature rises again.

摘要： PURPOSE:To eliminate the biasing in the electric charge of the film and to lower the cleaning temp. by consisting the film of the oxide of specific metals, CeO2, a solid acid compd., the oxide or carbonate of Li and Sr, and silicon binder and adjusting the pH of boiling extraction components to a weakly alkaline or neutral region. CONSTITUTION:The heat resistant film is formed of the oxides of one or >=2 kinds of the metals selected from Fe, Mn, Cu, Co, and Ni, the CeO2, the solid acid compd., the carbonate or oxide of one or >=2 kinds of the elements of the Li and Sr and the silicon binder and has the pH of the boiling extraction components in the weakly alkaline or neutral region. The cutting of the inter- carbon bonds of the oil in the oil contamination cleaning effect of this film is executed mainly by the solid acid effect and the oxidation by the oxidation effect of the metal oxide. The recombination of the carbon radicals generated by the solid acid is prevented by taking advantage of the basicity of the carbonate or oxide of the alkaline metals and alkaline earth metals. The pH of the boiling extraction components of the film is preferably in the neutral region or is alkaline in order to effectively develop the above-mentioned effects.

摘要： PURPOSE:To make it possible to recognize the increase/decrease in temperature of a heater by change in color, and thereby enhance the meaning of the existence as the heater by permitting the surface coated with oxide such as AL2O3 and the like to contain CeO2, and thereby manifesting thermochromism property. CONSTITUTION:A heater is formed with a coating surface layer 2 consisting of a main component composed of one kind or more than two kinds of oxide out of AL2O3, SiO2, TiO2, ZrO2 and La2O2 while CeO2 is contained in the surface 1 of the layer in order to be of thermochromism property. CeO2 is changed in color from light yellow to dark yellow at temperature equal to or more than 200 to 300 deg.C, and is returned to its original color so that it keeps repeatability. It is also excellent in heat resistance, chemical proof property and the like, it is thereby suitable as a thermochromism material forming the surface of the heater. Hence, when the aforesaid material is used for the heating body, color is changed depending on the increase/decrease in temperature, the meaning of the existence as the heater can thereby be enhanced.
