Abstract

The invention provides a manufacturing method of an electrothermal film layer, the electrothermal film layer, an electric heating disc and a cooking utensil. A mixture including indium tin oxid is used to form the electrothermal film layer on a surface of an insulation substrate at a high temperature of 450-600 degree via a vapor plating method, and then the electrothermal film layer and the insulation substrate are processed by an annealing film-forming process so that the electrothermal film layer is attached to the insulation substrate. The manufacturing method of the electrothermal film layer is simple and operation is convenient. The made electrothermal film layer can convert radiant heat energy into far infrared heat energy. Rapid increasing of the temperature is realized, the temperature lost during moisture eliminating can be reduced, an absorption speed of heating energy is increased, and heat energy losses are reduced so that radiation heat conduction efficiency is effectively improved and a purpose of energy saving is reached. The method, the layer, the heating disc and the cooking utensil satisfy a country requirement to product energy saving.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, relates to a method for manufacturing an electric heating film layer, an electric heating film layer, an electric heating plate and a cooking utensil. Background technique [0002] At present, domestic and foreign electric heating appliances (such as induction cookers, rice cookers and other cooking utensils) basically adopt traditional electric wire heating technology and electromagnetic heating technology. Energy saving and environmental protection requirements have caused a lot of energy waste. [0003] Therefore, how to improve the electric-to-thermal conversion energy efficiency ratio of electric heating appliances to improve the utilization rate of energy so as to better meet the national energy conservation and environmental protection requirements is a technical problem urgently needed to be solved by those skilled in the art. Contents of the invention [0004...
