In one specific embodiment of the present invention, the low-melting point metal may be a metal having a melting point not higher than 3000 ° C, and may be at least one selected from, for example, aluminum, calcium, zinc, and molybdenum. According to the findings of the inventor, the metal of this type is hot melted during hot spraying to partially oxidize, and thus the formed metal oxide is similar to the properties of the metal oxide in the ceramic pot body, and also the molten droplet of the formed metal or alloy (molten) drop) has a very good wet diffusion performance on the surface of the ceramic pot body, forming a micro metallurgical zone. Therefore, the formed self-adhesive transition metal layer and the ceramic pot body have excellent bonding strength.

According to another embodiment of the present invention, the low melting point metal may be any one selected from aluminum, calcium, zinc, and molybdenum, and the low melting point metal content may occupy 70 wt% or more of the self-adhesive transition metal layer.

Accordingly, when the self-adhesive transition metal layer in the scope of the present application is used, it can be ensured that it has excellent bonding strength between the ceramic pot body and the metal material layer.

In an embodiment of the present invention, referring to FIG. 2, the ceramic pot appliance may further include an enamel layer 300. According to a specific embodiment of the present invention, the enamel layer 300 may be disposed on at least a portion of the outer surface of the ceramic pot body 100, and the self-adhesive transition metal layer 200 may be at least a portion of the outer surface of the enamel layer 300. Can be placed on. In another specific embodiment of the present invention, the enamel layer 300 may be disposed on a part of the outer surface or the entire outer surface of the ceramic pot body 100, and the self-adhesive transition metal layer 200 may be a part of the outer surface of the enamel layer 300. Or it can be placed on the entire outer surface. In this regard, a person skilled in the art can select according to actual demand.

Can be. According to the inventor's discovery, first, a layer of glaze is applied to the outer surface of the ceramic pot body, and when sintered at a high temperature, the enamel softens at a high temperature to form an enamel layer on the outer face of the ceramic pot body. In addition, the high temperature softening point of the enamel is significantly lower than that of the ceramic pot body, so it can be ensured that it has excellent bonding strength between the ceramic pot body and the self-adhesive excessive metal layer. Specifically, first, a layer of glaze is applied to the outer surface of the ceramic pot body, and when sintered at a high temperature, the enamel softens at a high temperature to form an enamel layer on the outer surface of the ceramic pot body. Next, the ceramic pot on which the enamel layer is formed is preheated to 100 ° C to 300 ° C, and at the same time, the enamel layer is sanded so that the roughness of the enamel layer reaches Ry60 to 100㎛, and the low-melting metal is used through the next hot spray process. A self-adhesive transient metal layer is formed on the surface of the enamel layer by spraying.

According to another embodiment of the present invention, the self-adhesive transient metal layer 200 does not contain a magnetically permeable material, and referring to FIG. 3, the ceramic pot appliance may further include a heat conductive metal layer 400.

According to a specific embodiment of the present invention, the heat-conducting metal layer 400 may be disposed on at least a part of the outer surface of the self-adhesive transient metal layer 200, for example, as shown in FIG. 3, the heat-conducting metal layer 300 The silver self-adhesive transient metal layer 200 may be disposed on the entire outer surface. According to the findings of the inventor, the heat conductive metal layer is disposed on the outer surface of the self-adhesive transient metal layer, and the heat conducting metal layer lowers the temperature difference between the upper and lower temperature of the pot mechanism through being able to quickly transfer the amount of heat of the pot mechanism to the ceramic pot body, The ceramic pot body is uniformly heated, and further, the thermal stress generated in the thermal cycle process of the ceramic pot body can be reduced to prevent the metal material from falling off. Specifically, the thermal conductive metal layer may include at least one of silver, aluminum, copper, and zinc. According to the findings of the inventor, the heat-conducting metal layer of the type metal can significantly improve the heat conduction efficiency of the ceramic cooker than other types, thus lowering the temperature difference between the top and bottom of the cooker and improving the cooking effect of the cooker. have.

According to another specific embodiment of the present invention, the thickness of the thermally conductive metal layer is not particularly limited, and a person having ordinary knowledge in the art may select according to actual demand. In one specific example of the present invention, the thickness of the thermal conductive metal layer may be 0.04 to 0.4 mm, and preferably 0.2 mm. According to the findings of the inventor, if the thickness of the heat-conducting metal layer is less than 0.04 mm, the heat-conducting effect is not good, and heat cannot be transferred immediately, and if the thickness of the heat-conducting metal layer is greater than 0.4 mm, the heat-conducting metal layer has poor bonding strength. It is easily eliminated. Therefore, when the heat conductive metal layer in the thickness range of the present application is used, not only can the thermal conductivity performance of the cooker be significantly improved, but also the fall of the heat conductive metal layer can be prevented.

According to another embodiment of the present invention, the self-adhesive transient metal layer 200 does not contain a magnetically permeable material, and referring to FIG. 4, the ceramic pot appliance may further include a magnetically permeable layer 500.

The magnetically permeable layer is heated under electromagnetic action, and the amount of heat is quickly transferred to the ceramic pot body through the heat-conducting metal layer, so that the ceramic pot body is uniformly heated, and furthermore, it is produced during the thermal cycle of the ceramic pot body. It reduces thermal stress to prevent metal material from falling off. Specifically, the magnetic permeable layer may include at least one of nickel, iron, and cobalt, and is preferably a nickel-iron alloy magnetic permeable layer. According to the inventor's discovery, the metal magnetic permeable layer of this type can significantly improve the magnetic permeable performance of the cooker than other types.

In one specific example of the present invention, the thickness of the magnetic permeable layer may be 0.1 to 0.5 mm, and preferably 0.3 mm. According to the inventor's discovery, if the thickness of the magnetic permeable layer is less than 0.1 mm, the magnetic permeable power is small, so that the demand for the function cannot be satisfied. If the thickness of the magnetic permeable layer is greater than 0.5 mm, its resistance data is It is large, the heating energy efficiency is small, and at the same time, the bonding strength is poor. Therefore, when the magnetic permeable layer in the thickness range of the present application is used, it is possible to increase the magnetic permeation performance of the pot mechanism and to ensure that the pot mechanism has high quality.

According to another embodiment of the present invention, the self-adhesive transient metal layer 200 does not contain a magnetically permeable material, and referring to FIG. 5, the ceramic pot appliance may further include a protective layer 600.

However, if a protective layer is further disposed on the outer surface of the metal material, the protective layer can effectively prevent the metal material from rusting and dirt entering the pores, thus improving corrosion resistance, surface hardness, and service life of the cooker. have. Specifically, the protective layer may be at least one of a silicone resin layer, a high temperature anti-rust coating layer and a ceramic coating layer. According to the findings of the inventor, the use of the above-mentioned type of protective layer can significantly improve the service life of the ceramic cooker than other types.

In another specific embodiment of the present invention, the thickness of the protective layer is not particularly limited, and a person having ordinary skill in the art can select according to actual demand. In one specific example of the present invention, the thickness of the protective layer may be 0.05 to 0.2 mm, preferably 0.1 mm. According to the findings of the inventor, if the thickness of the protective layer is less than 0.05 mm, the rust-preventing ability of the protective layer is poor, and if the thickness is larger than 0.2 mm, the bonding force falls and falls off easily. Accordingly, when the protective layer in the thickness range of the present application is used, it is possible to increase the service life of the ceramic cooker and improve the quality of the cooker.

Accordingly, an enamel layer, a self-adhesive transient metal layer that does not contain a magnetic permeable material, a heat conductive metal layer, a magnetic permeable layer and a protective layer are sequentially disposed on the surface of the ceramic pot body. The self-adhesive transition metal layer is very dense and has a low porosity, and the self-adhesive metal has a low melting point, so that it is hot melted during hot spraying to partially oxidize to turn into a metal oxide, and when it collides with a ceramic substrate at high speed The metal oxide in the ceramic material and the micro-metallurgical reaction occur to form a solid bonding layer, thus ensuring that it has good bonding strength between the ceramic pot body and the metal material layer of the obtained pot mechanism. In addition, the disposed magnetic permeable layer can enable the pot mechanism to have a good electromagnetic heating function, so that the pot mechanism can not only implement the electromagnetic heating function, but also the self-adhesive transient metal layer and the heat conductive metal layer disposed between the magnetic permeable layer. The amount of heat generated can be quickly transferred to the body of the ceramic pot, thereby lowering the temperature difference between the top and bottom of the pot, and allowing the ceramic pot body to receive uniform heat. In addition, the protective layer disposed on the magnetic permeable layer can effectively prevent the rust of the metal material from entering the pores, thereby improving the corrosion resistance, surface hardness, and service life of the cooking utensils. It can satisfy people's demand for high-quality pot appliances.

According to another embodiment of the present invention, the self-adhesive transition metal layer 200 includes a magnetically permeable material, and the magnetically permeable material includes at least one of nickel, iron, and cobalt.

However, if a protective layer is further disposed on the outer surface of the metal material, the protective layer can effectively prevent the metal material from rusting and dirt entering the pores, thereby improving corrosion resistance, surface hardness, and service life of the cooker. Can be. Specifically, the protective layer may be at least one of a silicone resin layer, a high temperature anti-rust coating layer and a ceramic coating layer. According to the findings of the inventor, the use of the above-mentioned type of protective layer can significantly improve the service life of the ceramic cooker than other types.

According to a specific embodiment of the present invention, the thickness of the protective layer is not particularly limited, and a person having ordinary knowledge in the art may select according to actual demand. In one specific example of the present invention, the thickness of the protective layer may be 0.05 to 0.2 mm, preferably 0.1 mm. According to the findings of the inventor, if the thickness of the protective layer is less than 0.05 mm, the rust-preventing ability of the protective layer is poor, and if the thickness is larger than 0.2 mm, the bonding force falls and falls off easily. Therefore, the use of the protective layer in the thickness range of the present application can increase the service life of the ceramic pot and at the same time improve the quality of the pot.

Accordingly, a self-adhesive transient metal layer and a protective layer having a magnetically permeable material are sequentially disposed on the surface of the ceramic pot body. The self-adhesive transition metal layer is very dense, has a low porosity, and the self-adhesive metal contains a low melting point metal and a magnetic permeable material, so that it is hot melted during hot spraying to partially oxidize to turn into a metal oxide, ceramic When colliding with the substrate at a high speed, a metal oxide in the ceramic material and a micro metallurgical reaction occur to form a solid bonding layer, thus ensuring that it has good bonding strength between the ceramic pot body and the metal material layer of the obtained cooker. . In addition, since the formed self-adhesive transient metal layer can be provided with a self-permeable performance so that the pot mechanism of the above structure has a good electromagnetic heating function, the pot mechanism can not only implement the electromagnetic heating function, but also the ceramic of the pot mechanism. The bonding strength of the pot body and the metal layer is excellent, and it can satisfy people's demand for a healthy and eco-friendly high-quality pot apparatus.

In another aspect of the present invention, the present invention provides a method for manufacturing the above-described ceramic pot appliance. In an embodiment of the present invention, referring to FIG. 7, the method includes the following steps.

S100: Provide a ceramic pot body.

At this stage, the ceramic pot body may be any ceramic pot body present in the prior art.

S200: Self-adhesive excess metal is hot sprayed onto at least a portion of the outer surface of the ceramic pot body.

In this step, a self-adhesive transition metal layer is hot-sprayed on at least a portion of the outer surface of the ceramic pot body to form a self-adhesive transition metal layer on at least a portion of the outer surface of the ceramic pot body. According to the discovery of the inventor, in the hot spraying process, a metal is hot melted, and a part of it is oxidized to turn into a metal oxide, and when colliding with a ceramic substrate at high speed, a metal oxide in a ceramic material, for example, aluminum oxide, and micro metallurgical reaction occur To form a solid bonding layer, that is, to form a self-adhesive transient metal layer on the surface of the ceramic pot body. At the same time, the self-adhesive transient metal layer is very dense and has a low porosity, which can significantly improve the bonding strength between the metal material layer and the ceramic pot body (the bonding strength reaches 20 MPa), thereby allowing the pot mechanism to heat cycle In the process, the thermal stress is effectively relieved to prevent dropping out, and the cooker does not crack even after 50 to 260 ° C to 20 ° C high and low temperature shocks, so people demand for a healthy and eco-friendly high-quality cooker Can satisfy.

According to an embodiment of the present invention, a self-adhesive excessive metal layer can be formed by hot spraying on a part of the outer surface or the entire surface of the ceramic pot body, and a person having ordinary knowledge in this field can meet the actual demand. You can choose accordingly. For example, a self-adhesive transient metal layer may be formed by hot spraying the entire outer surface of the ceramic pot body. Accordingly, a self-adhesive transient metal layer is formed on the entire outer surface of the ceramic pot body, and the self-adhesive transient metal layer has excellent bonding strength with the ceramic pot body, so that the pot mechanism effectively relieves thermal stress during the thermal cycling process. There is no dropout, and thus the quality of the obtained cooker is improved.

According to another embodiment of the present invention, the self-adhesive transition metal may be a low melting point metal. According to the findings of the inventor, when a low melting point metal is used, in the hot spraying process, the low melting point metal is hot-melted to partially oxidize to turn into a metal oxide. For example, a micro-metallurgical reaction occurs with aluminum oxide and the like to form a solid bonding layer, thus ensuring that it has excellent bonding strength between the ceramic pot body and the formed self-adhesive transient metal layer.

According to another embodiment of the present invention, the specific type of the low-melting point metal is not particularly limited, and a person having ordinary skill in the art can select according to actual demand. In one specific embodiment of the present invention, the low-melting point metal may be a metal having a melting point not higher than 3000 ° C, and may be at least one selected from, for example, aluminum, calcium, zinc, and molybdenum. According to the findings of the inventor, the metal of this type is hot melted during hot spraying to partially oxidize, and thus the formed metal oxide is similar to the properties of the metal oxide in the ceramic pot body, and also the molten droplet of the formed metal or alloy is ceramic It has a very good wet diffusion performance on the surface of the pot body, forming a micro metallurgical zone. Therefore, the formed self-adhesive transition metal layer and the ceramic pot body have excellent bonding strength.

According to another embodiment of the present invention, the low melting point metal may be any one selected from aluminum, calcium, zinc, and molybdenum, and the low melting point metal content may occupy 70 wt% or more of the self-adhesive transition metal layer. According to the findings of the inventor, metals satisfying the above content range may be hot-melted and oxidized in a hot spraying process to be oxidized to generate metal oxides and micro-metallurgical reactions in the ceramic pot body to be combined. Therefore, it can be ensured that the formed self-adhesive excessive metal layer and the ceramic pot body have excellent bonding strength.

According to another embodiment of the present invention, the low melting point metal may be at least two selected from aluminum, calcium, zinc, and molybdenum, and the low melting point metal content may occupy 80 wt% or more of the self-adhesive transient metal layer. According to the findings of the inventor, metals satisfying the above content ranges are hot-melted and oxidized in a hot spraying process, so that metal oxides in the ceramic pot body and micro metallurgical reactions can be combined. Therefore, it can be ensured that the formed self-adhesive excessive metal layer and the ceramic pot body have excellent bonding strength.

According to another embodiment of the present invention, the thickness of the self-adhesive transient metal layer is not particularly limited, and a person having ordinary knowledge in the art can select according to actual demand. According to a specific embodiment of the present invention, the thickness of the self-adhesive transition metal layer may be 0.04 to 0.1 mm, and preferably 0.06 mm. According to the findings of the inventor, if the thickness of the self-adhesive transient metal layer is less than 0.04 mm, the bonding strength of the metal material layer and the ceramic material falls, and if the thickness of the self-adhesive transient metal layer is greater than 0.1 mm, the metal material layer Easily eliminated. Accordingly, when the self-adhesive transition metal layer in the scope of the present application is used, it can be ensured that it has excellent bonding strength between the ceramic pot body and the metal material layer.

Accordingly, a method of manufacturing a ceramic pot appliance according to an embodiment of the present invention can be obtained by manufacturing a ceramic pot appliance having excellent bonding strength between the above-described ceramic pot body and a metal material layer (bond strength reaches 20 MPa). Therefore, the cooker appliance effectively relieves thermal stress in the thermal cycling process so that no dropout occurs, and the obtained cooker appliance does not crack even after 50 to 260 ° C to 20 ° C high and low temperature shocks. And it can satisfy people's demand for eco-friendly high-quality cooker.

In an embodiment of the present invention, referring to FIG. 8, the method of manufacturing the above-described ceramic pot appliance further includes the following steps.

S300: Before hot spraying the self-adhesive transition metal on at least a portion of the outer surface of the ceramic pot body, glaze is applied to at least a portion of the outer surface of the ceramic pot body in advance.

In the above process, specifically, before hot spraying the self-adhesive transition metal on at least a portion of the outer surface of the ceramic pot body, a glaze is applied to at least a portion of the outer surface of the ceramic pot body in advance, followed by sintering at a high temperature, thereby at least An enamel layer is formed on some outer surfaces, and after the enamel layer is sanded, a self-adhesive transition metal layer is formed by hot spraying a self-adhesive transition metal on at least a portion of the enamel layer again. According to a specific embodiment of the present invention, the enamel layer may be formed on a portion of the outer surface or the entire outer surface of the ceramic pot body, and the self-adhesive transition metal layer may be formed on a portion of the outer surface or the entire outer surface of the enamel layer. On the other hand, a person having ordinary knowledge in the art can select according to actual demand. Preferably, the enamel layer is formed on the entire outer surface of the ceramic pot body, and the self-adhesive excessive metal layer is also applied to the entire outer surface of the enamel layer. Can be formed. According to the inventor's discovery, first, a layer of glaze is applied to the outer surface of the ceramic pot body, and when sintered at a high temperature, the enamel softens at a high temperature to form an enamel layer on the outer face of the ceramic pot body. In addition, the high temperature softening point of the enamel is significantly lower than that of the ceramic pot body, so it can be ensured that it has excellent bonding strength between the ceramic pot body and the self-adhesive excessive metal layer. Specifically, first, a layer of glaze is applied to the outer surface of the ceramic pot body, and when sintered at a high temperature, the enamel softens at a high temperature to form an enamel layer on the outer surface of the ceramic pot body. Next, the ceramic pot on which the enamel layer is formed is preheated to 100 ° C to 300 ° C, and at the same time, the enamel layer is sanded so that the roughness of the enamel layer reaches Ry60 to 100㎛, and the low-melting metal is used through the next hot spray process. A self-adhesive transient metal layer is formed on the surface of the enamel layer by spraying.

In another embodiment of the present invention, the self-adhesive transition metal layer does not contain a magnetically permeable material, and referring to FIG. 9, the method of manufacturing the ceramic pot appliance may further include the following steps.

S400: Hot conductive metal is hot sprayed on at least a portion of the self-adhesive transition metal layer.

In this step, the thermally conductive metal is hot sprayed on at least a portion of the outer surface of the self-adhesive transient metal layer so that a thermally conductive metal layer is formed on at least a portion of the outer surface of the self-adhesive transient metal layer. For example, a thermally conductive metal layer may be formed on the entire outer surface of the self-adhesive transient metal layer. According to the findings of the inventor, the heat conductive metal layer is disposed on the outer surface of the self-adhesive transient metal layer, and the heat conducting metal layer lowers the temperature difference between the upper and lower temperature of the pot mechanism through being able to quickly transfer the amount of heat of the pot mechanism to the ceramic pot body, The ceramic pot body is uniformly heated, and further, the thermal stress generated in the thermal cycle process of the ceramic pot body can be reduced to prevent the metal material from falling off. Specifically, the thermal conductive metal layer may include at least one of silver, aluminum, copper, and zinc. According to the findings of the inventor, the heat-conductive metal layer formed of the above-mentioned type of metal can significantly improve the heat conduction efficiency of the ceramic cooker than other types, thus lowering the temperature difference between the top and bottom of the cooker and reducing the cooking effect of the cooker. Can improve.

According to another specific embodiment of the present invention, the thickness of the thermally conductive metal layer is not particularly limited, and a person having ordinary knowledge in the art may select according to actual demand. According to one specific example of the present invention, the thickness of the thermally conductive metal layer may be 0.04 to 0.4 mm, and preferably 0.2 mm. According to the findings of the inventor, if the thickness of the heat-conducting metal layer is less than 0.04 mm, the heat-conducting effect is not good, heat cannot be transferred immediately, and if the thickness of the heat-conducting metal layer is greater than 0.4 mm, the bonding strength of the heat-conducting metal layer is poor. It is easily eliminated. Therefore, when the heat conductive metal layer in the thickness range of the present application is used, not only can the thermal conductivity performance of the cooker be significantly improved, but also the fall of the heat conductive metal layer can be prevented.

According to another embodiment of the present invention, the self-adhesive transient metal layer does not contain a magnetically permeable material, and as shown in FIG. 10, the method of manufacturing the ceramic pot apparatus may further include the following steps.

S500: The magnetically permeable metal is hot sprayed on at least a portion of the outer surface of the thermal conductive metal layer.

In this step, the magnetically permeable metal is hot sprayed on at least a portion of the outer surface of the thermally conductive metal layer so that a magnetically permeable layer is formed on at least a portion of the outer surface of the thermally conductive metal layer. For example, a magnetic permeable layer may be formed on the entire outer surface of the thermally conductive metal layer. According to the inventor's discovery, by arranging the magnetically transmissive layer on the outer surface of the heat-conducting metal layer, it is possible to implement the electromagnetic heating function of the ceramic cooker. The magnetically permeable layer is heated under electromagnetic action, and the amount of heat is quickly transferred to the ceramic pot body through the heat-conducting metal layer, so that the ceramic pot body is uniformly heated, and furthermore, it is produced during the thermal cycle of the ceramic pot body. It reduces thermal stress to prevent metal material from falling off. Specifically, the magnetically permeable metal may include at least one of nickel, iron, and cobalt, and is preferably a nickel-iron alloy magnetically permeable layer. According to the findings of the inventor, the metal magnetic permeable layer formed of the magnetic permeable metal of the above type can significantly improve the magnetic permeation performance of the cooker than other types.

According to another specific embodiment of the present invention, the thickness of the magnetic permeable layer is not particularly limited, and a person having ordinary knowledge in the art can select according to actual demand. In one specific example of the present invention, the thickness of the magnetic permeable layer may be 0.1 to 0.5 mm, and preferably 0.3 mm. According to the inventor's discovery, if the thickness of the magnetic permeable layer is less than 0.1 mm, the magnetic permeable power is small, so that the demand for the function cannot be satisfied. If the thickness of the magnetic permeable layer is greater than 0.5 mm, its resistance data is It is large, the heating energy efficiency is small, and at the same time, the bonding strength is poor. Therefore, when the magnetic permeable layer in the thickness range of the present application is used, it is possible to increase the magnetic permeation performance of the pot mechanism and to ensure that the pot mechanism has high quality.

According to another embodiment of the present invention, the self-adhesive transition metal layer does not contain a magnetically permeable material, and referring to FIG. 11, the method of manufacturing the ceramic pot appliance may further include the following steps.

According to the inventor's discovery, the metal material disposed on the outer surface of the ceramic pot body has a constant porosity, and the metal material is easily rusted and dirt easily enters the pores during use. However, if a protective layer is further disposed on the outer surface of the metal material, the protective layer can effectively prevent the metal material from rusting and dirt entering the pores, thus improving corrosion resistance, surface hardness and service life of the pot mechanism. Can be. Specifically, the protective layer may be at least one of a silicone resin layer, a high temperature anti-rust coating layer and a ceramic coating layer. According to the findings of the inventor, the use of the above-mentioned type of protective layer can significantly improve the service life of the ceramic cooker than other types.

According to the findings of the inventor, if the thickness of the protective layer is less than 0.05 mm, the rust-preventing ability of the protective layer is poor, and if the thickness is larger than 0.2 mm, the bonding force falls and falls off easily. Accordingly, when the protective layer in the thickness range of the present application is used, it is possible to increase the service life of the ceramic cooker and improve the quality of the cooker.

Accordingly, an enamel layer, a self-adhesive transient metal layer, a heat conducting metal layer, a magnetic permeable layer, and a protective layer without a magnetic permeable material are sequentially disposed on the surface of the ceramic pot body. The self-adhesive transition metal layer is very dense and has a low porosity, and the self-adhesive metal has a low melting point, so that it is hot melted during hot spraying to partially oxidize to turn into a metal oxide, and when it collides with a ceramic substrate at high speed The metal oxide in the ceramic material and the micro metallurgy reaction occur to form a solid bonding layer, thus ensuring that it has good bonding strength between the ceramic pot body and the metal material layer of the obtained pot mechanism. In addition, the disposed magnetic permeable layer can enable the pot mechanism to have a good electromagnetic heating function, so that the pot mechanism can not only implement the electromagnetic heating function, but also the self-adhesive transient metal layer and the heat conductive metal layer disposed between the magnetic permeable layer. The amount of heat generated can be quickly transferred to the body of the ceramic pot, thereby lowering the temperature difference between the top and bottom of the pot, and allowing the ceramic pot body to receive uniform heat. In addition, the protective layer disposed on the magnetic permeable layer can effectively prevent the rust of the metal material from entering the pores, thereby improving the corrosion resistance, surface hardness, and service life of the cooking utensils. It can satisfy people's demand for high-quality pot appliances.

According to another embodiment of the present invention, the self-adhesive transition metal layer may include a magnetically permeable material, and the magnetically permeable material may include at least one of nickel, iron, and cobalt.
