Abstract
An electrothermal film layer manufacturing method, an electrothermal film layer, an electrically-heating plate, and a cooking utensil. An electrothermal film layer is formed, by means of a spraying method, a deposition method or an evaporation plating method, on a surface of an insulation substrate with a temperature of 450 to 600 degrees by using a mixture comprising tin dioxide, antimony and fluorine; and then the electrothermal film layer is manufactured by performing annealing and filming processing on the electrothermal film layer and the insulation substrate. The electrothermal film layer manufacturing method is simple and is convenient to operate, the manufactured electrothermal film layer can convert radiant heat energy into infrared heat energy to radiate, allows heat to be rapidly increased, can reduce temperature loss caused by moisture exhaust, increase the speed of heat energy absorption, and decrease heat energy loss, and accordingly the radiation heat conduction efficiency is effectively improved, the objective of energy conservation is achieved, and the demands of a nation on energy conservation products are better satisfied.
