Abstract
The utility model relates to a ceramic vessel which is characterized by consisting of a ceramic vessel body and an electromagnetic heating layer which is arranged at the bottom of the ceramic vessel body. The electromagnetic heating layer is composed of silver, melting point adjusting material and surface tension adjusting material, wherein, the content of the silver is 75 percent to 98 percent; the content of the melting point adjusting material is 0.5 percent to 1.5 percent; the content of the surface tension adjusting material is 1.5 percent to 23.5 percent. Compared with the prior art, the ceramic vessel has the advantages of thin electromagnetic heating layer, high heat supply efficiency and uniform heat supply.
Description
Technical field:
The utility model relates to a kind of container, particularly ceramic vessel.
Background technology:
Existing electromagnetic heating layer of porcelain container has two kinds: a kind of is stainless steel, and this electromagnetic heating layer heat is poor from the heat-transfer effect that stainless steel is delivered on the ceramic vessel, and stainless steel comes off from ceramic vessel behind cold shrinkage and thermal expansion easily in the use; Another kind is to adopt the ceramic material sintering with electromagnetic heating performance to form in the ceramic vessel bottom, this kind electromagnetic heating layer, disclosed as Chinese patent application 200610052119.9, by iron, silver and fusing point are regulated material (as bismuth oxide), surface tension adjustment material (as boric acid) constitutes, wherein iron is main matter, consumption accounts for more than 70%, during making, above-mentioned substance is made into slurry, be applied to the ceramic vessel bottom then, form through oversintering again, this kind electromagnetic heating layer is owing to be main matter with iron, during high temperature sintering, be difficult to guarantee that iron is not oxidized, and the iron after the oxidation is not possess the electromagnetic heating performance, oxidized in order to reduce in the sintering process iron as far as possible, the measure of taking generally is to make electromagnetic heating layer have certain thickness, as the disclosed 0.3-0.8mm of above-mentioned patent, even so, the iron of part inevitably can be oxidized, and, being subjected to the restriction of electromagnetic heating layer thickness, slurry generally is the bottom that spreads upon ceramic vessel by the mode of smearing, like this, the electromagnetic heating layer thickness will be inhomogeneous, and each position heating of electromagnetic heating layer is just inhomogeneous, makes the ceramic vessel bottom be heated inhomogeneous, and, remain in the electromagnetic heating layer because part iron is the form with oxide, these materials have reduced the heat-transfer effect of electromagnetic heating layer, have influenced the heat supply usefulness of electromagnetic heating layer.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of electromagnetic heating layer ceramic vessel thin, that heat supply usefulness is high.
Ceramic vessel of the present utility model is to realize like this, constitute by ceramic vessel body, the electromagnetic heating layer that is arranged on ceramic vessel body bottom, electromagnetic heating layer is made of silver, fusing point adjusting material, surface tension adjustment material, wherein Yin content is 75%-98%, the content that fusing point is regulated material is 0.5%-1.5%, and the content of surface tension adjustment material is 1.5%-23.5%.Owing to adopted the main component of silver as electromagnetic heating layer, and, silver is the good metal of a kind of chemical stability, even under the high temperature of sintering process, also be very stable, like this, electromagnetic heating layer can be done very thinly, silver and the close contact of ceramic vessel bottom surface, help the rapid transmission of heat energy, and, because electromagnetic heating layer can be done very thinly, like this, electromagnetic heating layer is before sintering, can be by mode such as printing with its paving in the ceramic vessel bottom, electromagnetic heating layer will be very even like this, makes each position of electromagnetic heating layer generate heat even.The effect of surface tension adjustment material is to make electromagnetic heating layer can be adjacent to bottom surface at ceramic vessel securely.
It is the mixture of bismuth oxide or lead oxide or bismuth oxide and lead oxide that fusing point is regulated material.The surface tension adjustment material is a boric acid.
The utility model compared with the prior art, have electromagnetic heating layer thin, heat supply usefulness height, heat supply advantage of uniform.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, ceramic vessel of the present utility model is to realize like this, constitute by ceramic vessel body 2, the electromagnetic heating layer 1 that is arranged on ceramic vessel body 2 bottoms, electromagnetic heating layer 1 is made of silver, fusing point adjusting material, surface tension adjustment material, wherein Yin content is 75%-98%, the content that fusing point is regulated material is 0.5%-1.5%, and the content of surface tension adjustment material is 1.5%-23.5%.It is the mixture of bismuth oxide or lead oxide or bismuth oxide and lead oxide that fusing point is regulated material.The surface tension adjustment material is a boric acid.Ceramic vessel body 2 is purple satay kettle or purple husky cooker or other ceramic teapot or cooker.The thickness of electromagnetic heating layer 1 is 0.06-0.20mm.
Claims (2)
1, a kind of ceramic vessel is characterized in that being made of ceramic vessel body, the electromagnetic heating layer that is arranged on ceramic vessel body bottom.
2, ceramic vessel according to claim 1, the thickness that it is characterized in that electromagnetic heating layer is 0.06-0.2mm.
