Heating cooker using ceramic heating element and manufacturing method therefor
The present invention relates to a heating cooker using a ceramic heating element and a manufacturing method thereof, the method comprising: a cooker body preparation step; a heating element material preparation step of preparing any one or more selected from among mill scale, steelmaking slag and magnetite (Fe3O4); an inorganic binder preparation step of preparing, as an inorganic binder, a colloidal silica sol having a colloidal silica content of 8 to 30 wt %; a mixing step of mixing 20 to 40 parts by weight of the colloidal silica sol as the inorganic binder with 100 parts by weight of the heating element material, thereby making a heating material paste; an application step of applying the heating element paste to the bottom of the cooker body; and a drying and curing step of drying and curing the heating element paste, thereby forming a solid heating element.
