Embodiment 1

[0074] 1. Make a high borosilicate glass pot with a cut bottom. The pot body includes a pot body and a concave part connected to the pot body. The concave part extends outward to form a flat part;

[0075] 2. Prepare the glass plate and print the heating film on the back of the glass plate;

[0076] 3. Preparation of glass powder coating

[0077] 1. Preparation of glass powder: the proportion of glass powder is SiO 2 30%, Al 2 o 3 10%, B 2 o 3 15%, MgO 5%, ZnO 25%, CaO 15%; the above components were melted uniformly at 1450°C, water quenched, dried, and crushed to obtain D 50 = 2.5 μm powder, that is, to obtain glass powder;

[0078] 2. Metal powder: pure silver powder, D 50 <2μm;

[0079] 3. Soldering paste preparation: 15% of organic components, 5% of glass powder, and 80% of metal powder, fully stir the above components, and disperse evenly through a three-roller machine to obtain a paste-like sealing material;

[0080] 4. Apply a uniform layer of glass powder c...

Embodiment 2

[0084] 1. Make a high borosilicate glass pot with a cut bottom. The pot body includes a pot body and a concave part connected to the pot body. The concave part extends outward to form a flat part;

[0085] 2. Prepare the glass plate and print the heating film on the back of the glass plate;

[0086] 3. Preparation of glass powder coating

[0087] 1. Preparation of glass powder: the proportion of glass powder is SiO 2 40%, Al 2 o 3 10%, B 2 o 3 10%, MgO 5%, ZnO 25%, CaO 10%; the above components were melted uniformly at 1450°C, water quenched, dried, and crushed to obtain D 50 = 2.5 μm powder, that is, to obtain glass powder;

[0088] 2. Metal powder: pure copper powder, D 50 <2μm;

[0089] 3. Soldering paste preparation: 10% of organic components, 5% of glass powder, and 85% of metal powder, fully stir the above components, pass through a three-roller machine to disperse evenly, and obtain a paste-like sealing material;

[0090] 4. Apply a uniform layer of glass pow...

Embodiment 3

[0094] 1. Making a bottom-cut glass-ceramic pot, the pot body includes a pot body and a concave portion connected to the pot body, and the concave portion extends outward to form a flat portion;

[0095]2. Prepare the glass plate and print the heating film on the back of the glass plate;

[0096] 3. Preparation of glass powder coating

[0097] 1. Preparation of glass powder: the proportion of glass powder is SiO 2 60%, Al 2 o 3 15%, B 2 o 3 10%, MgO 5%, Li 2 O 4%, K 2 O 2%, P 2 o 5 2%, TiO 2 1%, ZrO 2 1%; the above components were melted uniformly at 1550°C, water quenched, dried, and pulverized to obtain D 50 = 2.5 μm powder, that is, to obtain glass powder;

[0098] 2. Metal powder: silver powder 95%, palladium powder 5%; D 50 <2μm;

[0099] 3. Soldering paste preparation: 15% of organic components, 5% of glass powder, and 80% of metal powder, fully stir the above components, and disperse evenly through a three-roller machine to obtain a paste-like sealin...

Abstract

The invention discloses a non-metal heating device which comprises a kettle body and a base, wherein the kettle body is composed of a non-metal kettle body with a cut bottom and a non-metal plate, andthe non-metal kettle body with the cut bottom and the non-metal plate are formed into an integrated structure through glass powder coating; and a heating device is arranged at the bottom of the non-metal plate. By means of the heating device, the body of the heating device is made of all nonmetal, and the problems of low cost, long service life, safety, mass production, easy cleaning and the likecan be solved at the same time.

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...
