As shown in fig. 1-7, the present application provides a pot, which includes a ceramic pot body 1, a magnetic conductive film 2, and a non-stick glaze layer 3. The ceramic pot body 1 is formed by firing any existing ceramic material, the ceramic pot body 1 can be fired into any appropriate shape and size according to the requirement, and the inner surface of the ceramic pot body 1 can be coated with a glaze layer 10; the magnetic conduction film 2 is arranged on the inner surface of the ceramic pot body 1, so that the pot can be heated through an induction cooker; the non-stick glaze layer 3 is attached to one side of the magnetic conduction film 2, which is far away from the ceramic pot body 1, so as to protect the magnetic conduction film 2 and prevent the food material from directly contacting the magnetic conduction film 2, thereby preventing the magnetic conduction film 2 from being corroded; the non-stick glaze layer 3 is arranged into a concave-convex structure, the thickness of the convex part 32 of the concave-convex structure is thick, the heat transfer is slow, the surface temperature is low, and the convex part 32 is in contact with food materials to play a supporting role, so that the food materials can be prevented from being stuck to the bottom of a pan to cause pan pasting; concave part 30 thickness of concave-convex structure is thinner, makes the heat can transmit to in the pot rapidly, plays the heating effect to eating the material through concave part 30 to improve the rate of heating of pan. In addition, because the thickness of the concave part 30 is thinner, the heat generated by the magnetic conduction film can be quickly absorbed by the soup in the pot, thereby effectively preventing the magnetic conduction film from being damaged due to overhigh temperature and effectively prolonging the service life of the magnetic conduction film.

Wherein, the non-stick glaze layer 3 is low-temperature glaze. On one hand, the low-temperature glaze has a certain self-cleaning non-stick effect, so that the cookware has higher non-stick performance, and the phenomenon that food materials are stuck to the bottom of the cookware to cause the cookware to be burnt is prevented; on the other hand, the sintering temperature of the low-temperature glaze is lower, generally 800-1200 ℃, so that the phenomenon that the magnetic conduction film 2 is melted or bubbles are caused due to overhigh temperature during sintering, the failure of the magnetic conduction film 2 or the reduction of the electromagnetic induction efficiency is caused, and the qualification rate of products is influenced.

Further, the thickness of the non-stick glaze layer 3 is in the range of 10 μm to 300 μm, for example, the thickness of the non-stick glaze layer 3 may be 10 μm, 30 μm, 50 μm, 65 μm, 80 μm, 90 μm, 100 μm, 110 μm, 140 μm, 160 μm, 190 μm, 200 μm, 230 μm, 260 μm, 280 μm or 300 μm, and the like, and the non-stick glaze layer 3 can be formed into a uniform and continuous film layer and can be prevented from cracking. When the thickness of the non-stick glaze layer 3 is less than 10 μm, the thickness of the non-stick glaze layer 3 is too thin, so that the thickness of the non-stick glaze layer 3 is uneven and the film layer is discontinuous, that is, the non-stick glaze layer 3 is difficult to completely cover the magnetic conductive film 2, so that the magnetic conductive film 2 is still corroded; when the thickness of the non-stick glaze layer 3 is larger than 300 μm, the thickness of the non-stick glaze layer 3 is too thick, which causes a large internal stress in the non-stick glaze layer 3, thereby causing cracking.

Specifically, one side of the non-stick glaze layer 3 facing the magnetic conductive film 2 is a flat surface, so that the magnetic conductive film 2 has a uniform thickness; the side of the non-stick glaze layer 3 departing from the magnetic conduction film 2 is a concave-convex surface so as to form a convex part 32 for supporting food materials and a concave part 30 for heating the food materials.

Furthermore, the thickness difference between the protrusions 32 and the recesses 30 is 235 μm to 290 μm, for example, the thickness difference between the protrusions 32 and the recesses 30 may be 235 μm, 240 μm, 245 μm, 250 μm, 255 μm, 260 μm, 265 μm, 270 μm, 275 μm, 280 μm, 285 μm or 290 μm, etc., so that the non-stick glaze layer 3 has high strength and the service life of the non-stick glaze layer 3 is prolonged while preventing the food from sticking to the bottom of the pan to form a pan. When the thickness difference between the convex part 32 and the concave part 30 is less than 235 microns, the surface of the non-stick glaze layer 3 is too gentle, and the food material is easily supported at the convex part 32 and the concave part 30 at the same time, so that the food material is still easily adhered to the bottom of a pan to generate a pan; when the thickness difference between the convex part 32 and the concave part 30 is larger than 290 μm, the thickness difference between the convex part 32 and the concave part 30 is too large, which results in too low strength of the convex part 32, and the non-stick glaze layer 3 is easily broken or dropped due to abrasion, etc., thereby causing failure of the non-stick glaze layer 3.

Further, the thickness of the recess 30 is 10 μm to 15 μm, for example, the thickness of the recess 30 may be 10 μm, 11 μm, 12 μm, 13 μm, 14 μm or 15 μm, etc. to ensure that the non-stick glaze layer 3 forms a continuous film layer and to ensure the heating speed of the pot. When the thickness of the concave part 30 is less than 10 μm, the non-stick glaze layer 3 is easy to form an exposed part at the concave part 30, thereby losing the protection function; when the thickness of the recesses 30 is greater than 15 μm, the thickness of the nonstick glaze layer 3 in the recesses 30 is too large, resulting in a decrease in the heat transfer rate.

Further, the thickness of the protrusions 32 is 250 μm to 300 μm, for example, the thickness of the protrusions 32 may be 250 μm, 255 μm, 260 μm, 265 μm, 270 μm, 275 μm, 280 μm, 285 μm, 290 μm, 295 μm or 300 μm, etc. to prevent the food material from sticking to the bottom of the pan to form a pan, and to prevent the non-stick glaze layer 3 from cracking. When the thickness of the convex portion 32 is less than 250 μm, it is difficult to satisfy the requirement of the thickness difference between the convex portion 32 and the concave portion 30, so that the bottom blur is still easily generated; when the thickness of the protrusions 32 is larger than 300 μm, the thickness of the protrusions 32 is too large, so that the non-stick glaze layer 3 is easily cracked.

Specifically, the composition of the magnetic conductive film 2 includes a magnetic conductive material and an auxiliary material, the magnetic conductive material may be one or a mixture of at least two of iron, cobalt, and nickel, the auxiliary material may be, for example, copper or aluminum, and the auxiliary material may improve the film forming performance of the magnetic conductive material and have high thermal conductivity. The magnetic conduction membrane 2 that this application embodiment provided directly sets up in the internal surface of the ceramic pot body 1, need not to change the original structure of the ceramic pot body 1, can simplify processing technology, reduces the manufacturing cost of pan.

Further, the thickness of the magnetic conductive film 2 is 10 μm to 100 μm, for example, the thickness of the magnetic conductive film 2 may be 10 μm, 20 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, or 100 μm, etc., which not only enables the magnetic conductive film 2 to form a uniform and dense film layer, ensures that the magnetic conductive film 2 has a high electromagnetic induction efficiency, but also prevents the magnetic conductive film 2 from cracking. When the thickness of the magnetic conduction film 2 is less than 10 μm, the film layer of the magnetic conduction film 2 is discontinuous due to the excessively thin thickness of the magnetic conduction film 2, so that the electromagnetic induction efficiency of the magnetic conduction film 2 is difficult to meet the requirement, and the heating power is reduced; when the thickness of the magnetic conductive film 2 is greater than 100 μm, the thickness of the magnetic conductive film 2 is too large, which causes the internal stress of the magnetic conductive film 2 to be too large and cracks to be generated.

In one embodiment, referring to fig. 2, the magnetic conductive film 2 is disposed on the bottom surface of the ceramic pot body 1 and radially extends to abut against the sidewall of the ceramic pot body 1, so as to form a larger heating area, and enable the ceramic pot to achieve higher heating power.

In another embodiment, referring to fig. 3, the magnetic conductive film 2 is disposed on the bottom surface of the ceramic pot body 1, and a gap is left between the magnetic conductive film 2 and the sidewall of the ceramic pot body 1, so that the magnetic conductive film 2 is disposed on the flat region of the bottom surface of the ceramic pot body 1 to prevent the magnetic conductive film 2 from generating deformation such as wrinkles, and to increase the reliability of the attachment of the magnetic conductive film 2 to the ceramic pot body 1, thereby preventing the magnetic conductive film 2 from falling off. Wherein, the non-stick glaze layer 3 should completely guide the surface and edge of the magnetic film 2, thus effectively prevent the magnetic film 2 from directly exposing and generating corrosion.

In another embodiment, referring to fig. 4, a transition fillet is arranged between the bottom surface and the side wall of the ceramic pot body 1, the magnetic conductive film 2 is arranged at the transition fillet, since the heating power is proportional to the projection area of the magnetic conductive film 2, the magnetic conductive film 2 is arranged at the transition fillet, the actual area of the magnetic conductive film 2 is increased without changing the projection area of the magnetic conductive film 2, so that the largest possible heating area can be formed without changing the heating power, the food material is heated more uniformly, and since the transition fillet has a certain inclination angle, the interaction force between the food material and the non-glaze layer 3 can be reduced, thereby effectively preventing the food material from sticking to generate a burnt pan.

Specifically, the magnetic conductive film 2 provided in the embodiment of the present application may be disposed in a circular structure, or may be disposed in an annular structure. When the magnetic conductive film 2 is disposed in a ring structure, the magnetic conductive film 2 may be disposed in a continuous ring region 20 (see fig. 5), or the magnetic conductive film 2 may be disposed in a plurality of (including two or more) concentric ring regions 20, and a ring gap 22 may be disposed between the plurality of concentric ring regions (see fig. 6).

Further, a plurality of hole sites 24 may be disposed on the magnetic conductive film 2 provided in the embodiment of the present application, the hole sites 24 penetrate through the magnetic conductive film 2 along the thickness direction of the magnetic conductive film 2, and each hole site 24 plays a role of exhausting air, so as to prevent bubbles from being generated between the magnetic conductive film 2 and the non-stick glaze layer 3, thereby increasing the reliability of the mutual connection between the two.

In the embodiment of the present application, reference may be made to the following method for disposing the magnetically conductive film 2 and the non-stick glaze layer 3 in the ceramic pot body:

firstly, mixing a magnetic conductive material and an auxiliary material to prepare metal slurry; then, uniformly coating or spraying the metal slurry on the surface of preset plastic paper, and drying to form a magnetic conduction film 2; then, forming a non-stick glaze layer 3 with a concave-convex structure on the surface of the magnetic conduction film 2 through a mould, and drying again; and finally, adhering the magnetic conduction film 2 containing the non-stick glaze layer 3 to the inner surface of the ceramic pot body 1, and sintering at low temperature to form the pot provided by the embodiment of the application.
