preparation example Construction

[0095] Correspondingly, the present invention also provides a method for preparing a non-metal heating plate for cooking, including:

[0096] 1. Select expansion coefficient -6 K -1 The ceramic substrate, its surface is polished;

[0097] It should be noted that the technical details of the ceramic substrate are the same as those described above, and will not be repeated here.

[0098] 2. Select expansion coefficient -6 K -1 A glass sheet whose thermal expansion coefficient differs from that of the ceramic substrate by -6 K -1 ;

[0099] It should be noted that the technical details of the glass sheet are the same as those described above, and will not be repeated here.

[0100] 3. The ceramic substrate and the glass sheet are bonded together and sintered to form an integrated structure to obtain a ceramic substrate covered with a glass sheet.

[0101] It should be noted that, after the ceramic substrate and the glass sheet are bonded together, they are preferably put int...

Embodiment approach

[0128] The grounding method of the present invention has multiple implementations, including:

[0129] Such as Figure 5 with Figure 7 As shown, as the first embodiment of the grounding method of the present invention, the conductor is directly the conductive glass sheet 11 or the conductive ceramic substrate 12, and the grounding member 162 is against the conductive glass sheet 11 or the conductive ceramic substrate 12. catch.

[0130] Conductive glass sheets can be realized in this way. You can choose conductive glass sheets, or you can sinter glass paste containing gold, silver, platinum, palladium, ruthenium, nickel, copper and other metals through high temperature sintering to obtain conductive glass sheets. pieces of glass.

[0131] Specifically, the conductive ceramic substrate can be realized in this way. During the preparation process of the ceramic substrate, conductive materials are added to finally produce a ceramic substrate with certain conductivity.

[0132...

Embodiment 1

[0146] 1. Choose a 2.0mm thick silicon carbide ceramic substrate (the thermal expansion coefficient is about 4.5×10 -6 K -1 ) and 0.1mm thick silica-alumina glass sheet (thermal expansion coefficient is about 3.7×10 -6 K -1 ), bond the ceramic substrate and the glass sheet, and sinter at 950° C. for 10 minutes to obtain a composite substrate. Then screen-print SiO on the backside of the SiC ceramic substrate 2 -Al 2 o 3 -B 2 o 3 The insulating dielectric slurry is sintered at 850° C. for 10 minutes to form a film to form an insulating glaze layer to obtain a composite ceramic substrate.

[0147] 2. The performance test results of the above composite ceramic substrate are as follows:

[0148]

[0149] The composite ceramic substrate has excellent comprehensive performance and is suitable for use as a heating disk substrate of a glass jug.

Abstract

The invention discloses a nonmetal heating plate for cooking, and the heating plate sequentially comprises a glass sheet, a ceramic substrate, an insulating glaze layer and a heating body; the front surface of the ceramic substrate and the glass sheet are attached and form an integrated structure through sintering, the insulating glaze layer is arranged on the back surface of the ceramic substrate, and the heating body is arranged on the insulating glaze layer. Correspondingly, the invention further discloses a preparation method of the non-metal heating plate for cooking and a heating deviceadopting the non-metal heating plate for cooking. The non-metal heating plate is designed, the non-metal kettle body with the cut bottom is connected with the non-metal heating plate to form the integrated all-glass kettle body, and the problems of low cost, long service life, safety, mass production, easiness in cleaning and the like can 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 plate for cooking and a preparation method thereof, and a heating device using the non-metal heating plate 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 manufactu...
