When the coating 2 is arranged on the outer surface of the body 1, the body 1 is uniformly heated by the first concave-convex structure, and the body 1 is favorable for uniformly conducting heat to food.

Referring to fig. 1, according to some embodiments of the present invention, the coating 2 is a cold spray coating. The cold spraying layer prepared by the cold spraying technology has good bonding performance with the body 1, and has high density, low porosity and high thermal conductivity. This design improves the structural strength of the container 100 and the heating effect on the food, and at the same time, when the body 1 is an iron member, the dense coating 2 covering the surface of the body 1 can reduce the risk of rusting of the body 1.

Each first protrusion 211 extends in the circumferential direction of the body 1, and a first groove 212 is defined between adjacent first protrusions 211. When the coating 2 is provided on the inner surface of the body 1, when the container 100 is used for boiling water or heating food with more soup, the thickness of the first protrusion 211 is larger, the temperature is relatively lower, the thickness of the first groove 212 is smaller, the temperature is relatively higher, and the adjacent first protrusion 211 and first groove 212 can locally make the heated object heated unevenly, thereby promoting the local liquid flow.

When the coating 2 is arranged on the inner surface of the body 1 and the coating 2 is a heat-conducting coating, the design can avoid the problem that the heat-conducting effect of the first coating 21 is reduced due to the fact that the first protrusion 211 is too thick, the good bonding strength of the coating 2 and the body 1 is ensured, and meanwhile the risk of fracture of the first coating 21 can be reduced.

Referring to fig. 2 and 3, according to some alternative embodiments of the present invention, the minimum thickness h2 of the first coating layer 21 at the first groove 212 is not less than 80 um. If the minimum thickness h2 of the first coating layer 21 at the first groove 212 is too small, and the coating layer 2 is disposed on the inner surface of the body 1, the heat conductive effect of the first coating layer 21 is reduced when the coating layer 2 is a heat conductive coating layer, and a good heat conductive effect of the first coating layer 21 is ensured by defining the minimum thickness h2 of the first coating layer 21 at the first groove 212 within a proper range. On the other hand, when the body 1 is an iron member, such a design can reduce the risk of rusting of the body 1 caused by water passing through the pores of the first coating layer 21.

The design can avoid the first protrusion 211 and the first groove 212 from forming a step structure with a large fall, reduce the risk of cracking of the first coating 21, and improve the structural strength of the first coating 21.

Referring to fig. 2 and 3, according to some alternative embodiments of the present invention, the maximum thickness of the first coating layer 21 is the same at the plurality of first protrusions 211, which can improve the uniform heating effect of the container 100 on the food.

Referring to fig. 4, according to some optional embodiments of the present invention, the maximum thickness of the first coating layer 21 at the first protrusion 211 is sequentially increased in a direction radially inward from the body 1 (i.e., a direction from the edge of the body 1 to the center of the body 1, referring to a direction D in fig. 2). Since the central area closer to the bottom of the container 100 is heated to a greater degree, the maximum thickness of the first coating layer 21 at the first protrusions 211 in the radial inward direction of the body 1 is sequentially increased, and the heat transfer efficiency of the central area of the bottom of the container 100 can be improved. Further, when the coating layer 2 is formed on the inner surface of the body 1, and the coating layer 2 is a heat conductive coating layer, it is arranged that the maximum thickness of the first coating layer 21 at the first protrusions 211 increases in order from the radially inward direction of the body 1, and the generation of bubbles at the central region of the bottom of the container 100 can be promoted. The coating 2 is formed on the outer surface of the body 1, and when the coating 2 is a magnetic conductive coating, the maximum thicknesses of the first coating 21 at the first protrusions 211 in the radial inward direction of the body 1 are sequentially increased, so that the electromagnetic heating efficiency of the container 100 can be improved, and the uniformity of heat conduction of the container 100 is promoted. On the other hand, when spraying the first heat conductive coating layer 21, the spray gun may spray a plurality of coating layers 2 in a circular ring shape on the bottom surface of the container 100 by rotating the container 100 around the central axis of the container 100, the plurality of coating layers 2 in a circular ring shape constituting the first coating layer 21. Since the diameter of the circumference is gradually reduced in the direction radially inward from the body 1, it is difficult to spray the inner ring coating 2 as the coating 2 having a small thickness. By providing the first protrusions 211 whose maximum thickness is sequentially increased in the radially inward direction of the body 1, the difficulty of the process of forming the plurality of first protrusions 211 by spraying is reduced.

Referring to fig. 2, further, the first coating layer 21 is formed with a central protrusion at the center of the bottom of the body 1, the maximum thickness of the first coating layer 21 at the central protrusion is greater than the maximum thickness of the first coating layer 21 at the first protrusion, the thickness of the coating layer 2 at the central area of the bottom of the body 1 can be increased, and the thickness of the coating layer 2 is increased in a radially inward step shape, so that a strong heat convection phenomenon can be formed at a thinner and thicker portion of the coating layer 2, the boiling effect of food in the container 100 is enhanced, and the cooking effect of food in the container 100 is more uniform.

Referring to fig. 3, according to some alternative embodiments of the present invention, the spacing between adjacent first protrusions 211 decreases in sequence in a direction radially inward from the body 1. The coating 2 is formed on the inner surface of the body 1, and when the coating 2 is a heat conducting coating, the heat receiving capacity of the central area of the bottom of the container 100 is high, and the distances among the first protrusions 211 are sequentially reduced, so that the heat transfer area of the center of the container 100 can be increased, and the heat transfer efficiency of the center can be improved. The coating 2 is formed on the outer surface of the body 1, when the coating 2 is a magnetic conductive coating, because the magnetic field at the central part of the container 100 is strong, the heat generated by electromagnetic induction is more, and the distance between the adjacent first bulges 211 arranged at the central part is reduced in sequence, so that the dissipation of heat can be accelerated, the over-high temperature at the central area of the container 100 is prevented, and the uniformity of the overall temperature of the container 100 is improved.

Referring to fig. 2 and 3, according to some alternative embodiments of the present invention, the width of the first protrusion 211 on the same cross section (the width refers to the dimension of the first protrusion 211 in the radial direction of the body 1) decreases in sequence in the direction from the radial inside of the body 1, wherein the cross section is a plane parallel to the bottom of the body 1. The coating 2 is formed on the inner surface of the body 1, and when the coating 2 is a heat conductive coating, since the heat received at the central region of the bottom of the container 100 is high, the widths of the first protrusions 211 are sequentially reduced, so that the heat transfer efficiency at the center of the container 100 can be improved. The coating 2 is formed on the outer surface of the body 1, when the coating 2 is a magnetic conductive coating, because the magnetic field at the central part of the container 100 is strong, the heat generated by electromagnetic induction is more, the width of the first protrusion 211 is reduced in sequence, so that the dissipation of heat can be accelerated, the over-high temperature at the central area of the container 100 is prevented, and the uniformity of the overall temperature of the container 100 is improved.
