Description

A magnetic ceramic baking tray structure Technical Field

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

[0002] At present, the existing baking trays mainly adopt indirect heating by electric heating. Since the heat dissipation surface of the traditional electric heat source is relatively small, the heat energy generated by the electric energy cannot be quickly transferred to the heated object during the electric heat conversion process, causing the heat to be too concentrated on the electric heating element. The electric heating element itself quickly becomes hot, and a large part of the electric heat is converted into light energy and dissipated, resulting in low electric heat conversion efficiency and low heating efficiency. Some also use far-infrared heating, but a special far-infrared heating device must be set up to heat the baking tray, which has a complicated structure.

[0003] Furthermore, in order to heat the baking pan directly and quickly, someone designed an electric baking pan. For example, the utility model patent with authorization announcement number CN2426259 and authorization announcement date April 4, 2001, discloses an electric baking pan. The baking pan body is made of ceramic or glass material. A conductive heating film layer is coated on the heating surface set at the bottom of the baking pan body. Conductive adhesive wires are adhered to the two sides of the conductive heating film layer for connection to an external power supply. After the conductive heating film layer is energized and heated, the electric baking pan can be directly and quickly heated. The far infrared rays emitted by the baking pan body can make the frying and grilling process clean and hygienic. However, coating the conductive heating film layer on the heating surface set at the bottom of the baking pan body makes the conductive heating film layer external. The external conductive heating film layer is not protected and is easily scratched, has a short service life, and greatly reduces the thermal conductivity efficiency. Summary of the Invention

[0004] The problem to be solved by the utility model is to provide a magnetic conductive ceramic baking pan structure, which can be directly applied to an induction cooker to extend the service life.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0006] A magnetic ceramic baking tray structure includes a ceramic baking tray body, a heating surface is provided at the center of the bottom of the ceramic baking tray body, and two oppositely arranged lifting ears are provided at the edge of the ceramic baking tray body. The structure is characterized in that: the ceramic baking tray body includes, from bottom to top, a lower protective layer, a ceramic blank layer, a magnetic conductive layer, an upper protective layer and a functional glaze layer; the magnetic conductive layer at least covers the heating surface.

[0007] By providing a lower protective layer on the lower surface of the ceramic green sheet, the lower surface of the ceramic green sheet can be effectively protected. The magnetic conductive layer covers at least the entire heating surface of the bottom of the ceramic baking pan body, giving the ceramic baking pan body magnetic conductivity and improving magnetic conductivity efficiency. This allows the ceramic baking pan to be used directly on an induction cooker, eliminating the need for electrical heating of the baking pan itself during grilling.

[0008] By placing an upper protective layer on the upper surface of the magnetic layer, the magnetic layer can be effectively protected, reducing scratches on the magnetic layer and extending the service life of the ceramic bakeware. Applying a functional glaze layer on the upper surface of the upper protective layer can reduce food adhesion during grilling, preventing food from sticking to the ceramic bakeware body, improving the cleanability and durability of the ceramic bakeware body, and protecting the upper protective layer, thereby enhancing product quality and service life.

[0009] In a preferred embodiment, both the lower and upper 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.

[0010] 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.

[0011] In a preferred embodiment, the thickness of the magnetic conductive layer is in the range of 0.05mm-1.00mm. The thickness of the magnetic conductive layer is determined by the rated power. The power is directly proportional to the thickness. The thickness range is approximately between 0.05mm-1.00mm.

[0012] 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.

[0013] 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.

[0014] 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 baking tray.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The utility model can effectively protect the magnetic conductive layer, reduce the phenomenon of scratching of the magnetic conductive layer, extend the service life of the ceramic baking tray, and directly apply the baking tray to the induction cooker, so there is no need to electrically heat the baking tray itself during grilling.

The ceramic baking tray body 1 includes, from bottom to top, a lower protective layer 13, a ceramic blank layer 14, a magnetic conductive layer 15, an upper protective layer 16 and a functional glaze layer 17; the magnetic conductive layer 15 at least covers the heating surface 11.

[0023] By providing a lower protective layer 13 on the lower surface of the ceramic green sheet layer 14, the lower surface of the ceramic green sheet layer 14 can be effectively protected. The magnetic conductive layer 15 at least covers the entire heating surface 11 at the bottom of the ceramic baking pan body 1, making the ceramic baking pan body 1 magnetically conductive and improving the magnetic conductivity. This allows the ceramic baking pan to be used directly on an induction cooker, eliminating the need for electrical heating of the baking pan itself during grilling.

[0024] Providing an upper protective layer 16 on the upper surface of magnetically conductive layer 15 effectively protects magnetically conductive layer 15, reduces scratching, and extends the lifespan of the ceramic bakeware. Applying a functional glaze layer 17 on the upper surface of upper protective layer 16 reduces food adhesion during grilling, preventing it from sticking to ceramic bakeware body 1. This improves the cleanability and durability of ceramic bakeware body 1, protects upper protective layer 16, and enhances product quality and service life.

[0028] The magnetic conductive layer 15 is disposed on the ceramic green body layer 14 by hot melting.

The surface layer 151 is coated on the upper surface of the bottom layer 152. The bottom layer 152 serves as the base layer of the magnetic conductive layer 15 and can provide good support and bearing capacity for the surface layer 151.

[0030] The surface layer 151 is made of a mixture of titanium and silver, while the bottom layer 152 is made of a mixture of silver, cobalt, aluminum, and nickel. Both the titanium and silver surface layer 151 and the silver, cobalt, aluminum, and nickel bottom layer 152 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 baking tray.
