Abstract

The invention discloses a nonmetallic heating device which comprises a nonmetallic pot and a heating base, wherein the heating base comprises a heating plate; the nonmetallic pot is a bottom-cut pot;at least one glass function coating is formed on the surface of the heating plate by coating first glass powder paint; the glass function coating and the nonmetallic pot are molded into an integral structure by virtue of second glass powder paint, so that the nonmetallic pot is fixedly connected with the heating base; and foods in the nonmetallic pot are separated from the heating plate by virtueof the glass function coatings. With the adoption of the nonmetallic heating device disclosed by the invention, the heating device body is made from all non-metals, and the nonmetallic heating devicecan achieve the advantages of being low in cost, long in service life, safe, capable of realizing mass production, easy to clean and the like.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a non-metal heating device for cooking. Background technique [0002] Kettles are a necessity of life. From gas-fired kettles to smart plastic electric kettles, to stainless steel electric kettles, to half-glass kettles, and all-glass kettles, products are constantly being updated. The physical properties of glass are stable, safe, and clean. It will not chemically react with heated food, and there will be no hidden worries of heavy metals. The transparent body of glass can penetrate far-infrared rays to improve water quality and optimize water sources. [0003] The current all-glass kettle generally has several technologies: transparent nano-film, carbon film and thick film. The former two types have fast power attenuation and have been abandoned by various manufacturers. The latter has good power stability, but has high process requirements and strict requirements...
