Description

A magnetic ceramic pot structure Technical Field

[0001] The utility model relates to a cooking utensil, in particular to a magnetic conductive ceramic pot structure. Background Art

[0002] Ceramic materials lack the magnetic conductivity of metals, limiting their use in induction cooktops. Currently, the primary process for producing magnetic ceramic cookware involves baking a magnetic film directly onto the bottom of the ceramic, or applying a film to the ceramic body, followed by a glazing process and finally firing.

[0003] Patent applications with publication numbers CN105310460A and CN105310510A respectively disclose a method for manufacturing a ceramic pot, both of which are characterized in that a magnetic conductive electric heating film is pasted on the inner bottom surface of the ceramic pot and covered with a glaze layer. This approach has two disadvantages: first, the magnetic conductive electric heating film is pasted on the inner bottom surface of the ceramic pot, and the magnetic induction efficiency and thermal conductivity efficiency are both low; second, the magnetic conductive electric heating film is located between the ceramic blank and the glaze, affecting the adaptability of the ceramic blank and glaze, and easily causing the glaze surface to crack, thereby resulting in uneven mechanical strength of the ceramic pot bottom and pot body. Once impacted, the ceramic pot bottom will crack before the pot body.

[0004] Application No. ZL200310103236.X discloses a ceramic pot for an induction cooker, which is characterized in that a layer of magnetic conductive electric heating film is applied on the outer bottom surface of the ceramic pot. The disadvantage of this approach is that the external magnetic conductive electric heating film is not protected, is easily scratched, and has a short service life. Summary of the Invention

[0005] The problem to be solved by the utility model is to provide a magnetic conductive ceramic pot structure, which can increase the mechanical strength of the ceramic pot body and improve the magnetic conductive efficiency.

[0006] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0007] A magnetic ceramic pot structure includes a ceramic pot body and a pot cover, wherein the pot cover is covered in the upper end opening of the ceramic pot body. The characteristic is that the ceramic pot body includes an outer protective layer, a ceramic green body layer, a magnetic conductive layer, an inner protective layer and a functional glaze layer from the outside to the inside; the magnetic conductive layer at least covers the bottom of the ceramic pot body.

[0008] By providing an outer protective layer on the outer surface of the ceramic green body, the outer surface of the ceramic green body can be effectively protected. The magnetic conductive layer at least covers the entire bottom of the ceramic pot body, that is, the bottom of the ceramic pot body and a certain area above the bottom of the ceramic pot body are covered with the magnetic conductive layer. This makes the ceramic pot magnetically conductive, improves magnetic conductivity efficiency, and better meets the heating requirements of an induction cooker.

[0009] By applying an inner protective layer to the inner surface of the magnetic layer, the mechanical strength of the ceramic pot is increased, the risk of cracking the bottom of the pot when impacted is reduced, and the durability of the ceramic pot is improved. The inner protective layer also effectively protects the magnetic layer, reducing scratches on the magnetic layer and extending the life of the ceramic pot. Applying a functional glaze layer to the inner surface of the inner protective layer can reduce food adhesion during cooking, preventing food from sticking to the ceramic pot, improving the pot's ease of cleaning and durability, and protecting the inner protective layer, thereby enhancing product quality and service life.

[0010] In a preferred embodiment, both the outer and inner protective layers are glaze layers. The glaze layers are primarily composed of oxides and silicates, such as SiO2. These glaze layers are used as surface coatings for ceramic products, increasing their hardness, wear resistance, and aesthetics. High-temperature sintering is required to form a hard surface coating that creates a smooth surface.

[0011] In a preferred embodiment, the functional glaze layer is made of SiO2, which can be prepared by a sol-gel method and has a non-stick property.

[0012] In a preferred embodiment, the magnetic conductive layer extends from bottom to top and covers at least one quarter of the side wall of the ceramic pot body.

[0013] In a further preferred embodiment, the thickness of the magnetic conductive layer is in the range of 0.05 mm to 1.00 mm. The thickness of the magnetic conductive layer is determined by the rated power. The power is directly proportional to the thickness, and the thickness range is approximately between 0.05 mm and 1.00 mm.

[0014] In a further preferred embodiment, the magnetic conductive layer is provided on the ceramic green sheet by heat melting, attaching or printing. By providing the magnetic conductive layer on the ceramic green sheet through various processing methods, the flexibility of the manufacturing process can be improved and the production cost can be reduced.

[0015] In a preferred embodiment, the magnetic conductive layer includes a surface layer and a bottom layer, wherein the surface layer is coated on the upper surface of the bottom layer. The bottom layer serves as the base layer of the magnetic conductive layer and can provide good support and bearing capacity for the surface layer.

[0016] In a further preferred embodiment, the surface layer is made of a mixture of titanium and silver, and the bottom layer is made of a mixture of silver, cobalt, aluminum, and nickel. The titanium and silver surface layer and the silver, cobalt, aluminum, and nickel bottom layer both have high magnetic permeability and electrical conductivity, effectively distributing and conducting magnetic energy, improving magnetic conductivity, and enhancing the magnetic coupling efficiency between the electromagnetic coil and the ceramic pot body.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This magnetic ceramic pot structure has a magnetic conductive layer on the bottom of the ceramic pot body and a certain area from the bottom to the side wall, so that the ceramic pot has magnetic conductivity, improves the magnetic conductivity efficiency, and can better meet the heating requirements of the induction cooker.
