[0059] The pot and its production process according to the embodiments of the utility model are described below with reference to the drawings.

[0060] Referring to Figure 1 The utility model aims at providing a kind of pot embodiment.The pot mainly includes pot body 100, and the food to be cooked is used to be contained in the inside of pot body 100.According to the depth and shape of pot body 100, the pot can also be called pot dish, round pot, square pot, rhombic pot and the like.

[0061] In the embodiment, the pot body 100 can be single-layer, double-layer or multi-layer, and the material of the pot body 100 can include iron material, aluminum material and material meeting food requirements.

[0062] In some specific embodiments of the utility model, the pot can include handle connected to the pot body 100, and pot cover covering the pot body 100, the handle can be handle, or lifting handle, and can also have handle and lifting handle simultaneously.

[0063] On the inner surface or outer surface of the pot, concave-convex heat exchange surface 110 can be provided to increase the heat exchange area of the pot and improve the heat transfer efficiency and cooking quality.

[0064] In the embodiment, the inner surface of the pot body 100 is provided with the concave-convex heat exchange surface 110, and the concave-convex heat exchange surface 110 is located on the bottom wall of the pot body 100 to heat the food placed on the bottom wall of the pot body 100 sufficiently and facilitate heating from bottom to top.

[0065] In some specific embodiments of the utility model, the concave-convex heat exchange surface 110 can be distributed on the side wall of the pot body 100 to heat the food from the side, so as to realize balanced heating.

[0066] In the embodiment, the concave-convex heat exchange surface 110 comprises a plurality of heat exchange zones, the plurality of heat exchange zones comprise adjacent first heat exchange zones 120 and second heat exchange zones 130, the first heat exchange zones 120 can highlight reflection, and when the first heat exchange zones 120 highlight reflection, the second heat exchange zones 130 can relatively low-light reflection to the first heat exchange zones 120, so that the second heat exchange zones 130 can form the shadow of the first heat exchange zones 120 when highlighting.

[0067] In conclusion, the utility model discloses the first heat exchange zone 120 and second heat exchange zone 130 exist the difference of reflection by setting, and, the second heat exchange zone 130 can form the shadow of the first heat exchange zone 120 when highlighting, approximate to place solid article on the plane, thus, visually, the first heat exchange zone 120 and second heat exchange zone 130 cooperate to form the concave or convex solid structure, so that the visual estimation of the concave depth or convex height is greater than the actual value, provides more stereoscopic and unique visual feeling, promotes consumer purchase and use.

[0068] Thus, the embodiment can increase the heat exchange area, improve the heating efficiency, and improve the visual effect of the pot, make the texture of the pot more stereoscopic, provide unique visual feeling, and promote consumer purchase and use.

[0069] In some specific embodiments of the utility model, the first heat exchange zone 120 can comprise a plurality of first convex ribs 140 arranged side by side, the first convex ribs 140 can reflect light to make the first heat exchange zone 120 highlight reflection, the second heat exchange zone 130 comprises a plurality of second convex ribs 150 arranged side by side, and the second convex ribs 150 form an angle with the first convex ribs 140, so that the second heat exchange zone 130 can relatively low-light reflection to the first heat exchange zone 120.

[0070] It is easy to understand that, by setting the first convex rib 140 and the second convex rib 150, the first convex rib 140 and the second convex rib 150 can increase the heat exchange area, improve the heat exchange efficiency, improve the cooking quality, and the first convex rib 140 and the second convex rib 150 are not easy to wear, prolong the service life of the pot.

[0071] The utility model can also utilize the difference in visual perception of the human eye in the horizontal and vertical directions to form the visual perception of high-light reflection and low-light reflection, so that consumers can more easily obtain stereoscopic visual perception.

[0072] Meanwhile, the plurality of first convex ribs 140 arranged side by side and the plurality of second convex ribs 150 arranged side by side form a matrix-arranged geometric line pattern, which has significant advantages in stereoscopic sense, dynamic effect, innovation, watchability, fault tolerance, functionality and the like.

[0073] Meanwhile, the matrix-arranged geometric line pattern is visually more attractive, brings novel stereoscopic 3D effect and light and shadow dynamic change, and can exhibit unique visual levels under different angles.

[0074] Specifically, the rotating pot can also switch the reflection effect of the first heat exchange area 120 and the second heat exchange area 130, that is, switch from the state that the first heat exchange area 120 is high-brightness light-emitting and the second heat exchange area 130 is low-brightness light-emitting to the state that the first heat exchange area 120 is low-brightness light-emitting and the second heat exchange area 130 is high-brightness light-emitting.

[0075] With reference to Figure 2 In some specific embodiments of the present application, the first heat exchange area 120 and the second heat exchange area 130 can be parallel strips, the first convex rib 140 of the first heat exchange area 120 and the second convex rib 150 of the second heat exchange area 130 have an included angle, the included angle can be an acute angle, a right angle and an obtuse angle, and an array is arranged to generate a stereoscopic shape of a stepped structure.

[0076] With reference to Figure 3 In some specific embodiments of the present application, one of the first heat exchange area 120 and the second heat exchange area 130 can be annular, and the other of the first heat exchange area 120 and the second heat exchange area 130 is located on the inner side of the annular to form a stereoscopic shape of a boss structure.

[0077] With reference to Figure 4 In some specific embodiments of the present application, one of the first heat exchange area 120 and the second heat exchange area 130 can be triangular, the second heat exchange area 130 and the third heat exchange area 160 are arranged adjacent to each other, and the edge profile of the side of the second heat exchange area 130 and the third heat exchange area 160 close to the first heat exchange area 120 corresponds to two edges of the first heat exchange area 120 to form a stereoscopic shape of a triangular pyramid structure.

[0078] With reference to Figure 1In some specific embodiments of the utility model, can make multiple heat exchange area include with first heat exchange area 120 and second heat exchange area 130 adjacent third heat exchange area 160, first heat exchange area 120 has with second heat exchange area 130 adjacent left bevel boundary 170, with third heat exchange area 160 adjacent right bevel boundary 180, form vertical boundary 190 between second heat exchange area 130 and third heat exchange area 160, left bevel boundary 170, right bevel boundary 180 and vertical boundary 190 meet in a point, the external contour of at least one of first heat exchange area 120, second heat exchange area 130 and third heat exchange area 160 is parallelogram.

[0079] It is easy to understand that the embodiment forms left bevel boundary 170, right bevel boundary 180 and vertical boundary 190, and thus, first heat exchange area 120, second heat exchange area 130 and third heat exchange area 160 form a perspective corner of a cube, which is more easy to perceive the stereoscopic effect.

[0080] The perspective is a concept in mechanical drawing, which usually includes front view, top view, left view, right view and bottom view. The front view, top view, left view, right view and bottom view are all projections of a product in a certain direction, which can only obtain the planar structure of the product and cannot confirm the structural dimensions perpendicular to the view direction. For example, the rectangular pattern of the front view can only obtain the height and one of the length and width of the product, and cannot confirm the other one, so the product cannot be confirmed as a cube or a flat plate.

[0081] The perspective is a projection from the oblique direction of the product, which can usually display the top surface and two side surfaces of the product, and thus can also determine whether the product is a flat plate or a solid body according to the proportional relationship of the edges.

[0082] Therefore, when first heat exchange area 120, second heat exchange area 130 and third heat exchange area 160 form a perspective corner of a cube, the human vision will identify the pattern on the pot body 100 as a three-dimensional shape, produce visual impact, produce better visual effect, and achieve the design purpose.

[0083] It should be noted that left bevel boundary 170, right bevel boundary 180 and vertical boundary 190 can be composed of solid ribs or formed by the gap between first convex rib 140 and second convex rib 150, which can clearly distinguish the boundaries of the heat exchange area.

[0084] In this example, left bevel boundary 170, right bevel boundary 180 and vertical boundary 190 are identified by dashed lines to make them clear, but it does not mean that left bevel boundary 170, right bevel boundary 180 and vertical boundary 190 are solid.

[0085] In some specific embodiments of the present application, the left bevel boundary 170, the right bevel boundary 180 and the vertical boundary 190 can be straight lines to reduce manufacturing difficulty.

[0086] In some specific embodiments of the present application, the left bevel boundary 170, the right bevel boundary 180 and the vertical boundary 190 can be corrugated to meet diversified needs.

[0087] In some specific embodiments of the present application, the boundaries between the heat exchange zones are connected in an obtuse angle or acute angle mode to avoid right angles commonly seen in planar patterns and ensure the patterns have a three-dimensional effect.

[0088] In some specific embodiments of the present application, the included angle between the top surface and the side surface of the first protruding rib 140 and / or the second protruding rib 150 is 90±1°.

[0089] It is easy to understand that, in the present embodiment, the included angle between the top surface and the side surface of the protruding rib is 90°, which further reduces the reflection of the side surface of the first protruding rib 140 or the second protruding rib 150, so that the human visual focus is on the reflection effect of the protruding rib, thus making the visual perception along the extension direction of the protruding rib and the visual perception perpendicular to the extension direction of the protruding rib contrast very obviously, and the three-dimensional effect is more easily perceived.

[0090] In the present embodiment, the first protruding rib 140 and the second protruding rib 150 are both formed by the same process, and thus the first protruding rib 140 and the second protruding rib 150 have the same shape parameters.

[0091] In some specific embodiments of the present application, the width of the first protruding rib 140 and / or the second protruding rib 150 can be 0.25±0.05mm.

[0092] It is easy to understand that, in the present embodiment, the width of the protruding rib is set to 0.25±0.05mm, which avoids the line being too thick to lose the delicate level of detail and avoids the line being too thin to cause the pattern to be unclear, especially when observed at a distance, the line can be blurred, which weakens the overall visual effect.

[0093] In some specific embodiments of the present application, the height of the first protruding rib 140 and / or the second protruding rib 150 can be 0.1±0.02mm.

[0094] It is easy to understand that, in the present embodiment, the height of the protruding rib is set to 0.1±0.02mm, which avoids the protruding rib being too high to be broken and avoids the protruding rib being too low to reduce the three-dimensional effect.

[0095] In some specific embodiments of the utility model, the gap of the adjacent two first ribs 140 and / or the adjacent two second ribs 150 can be 0.11±0.02mm.

[0096] It is easy to understand that, by setting the gap of the ribs to 0.11±0.02mm, on the one hand, the pattern is not too compact, and the three-dimensional effect is lost, on the other hand, the pattern is too dense, which may cause the phenomenon of line interlacing blur, thereby the clarity is reduced.

[0097] Referring to Figure 5 The utility model also aims at providing a kind of embodiment of cookware production process, for producing the cookware of any one of the above, the inner surface of the pot body 100 is provided with concave-convex heat exchange surface 110, and production process mainly includes printing part, etching part, forming pot part, spraying part and assembly part.

[0102] Blank cleaning step S102 is to clean blank steel sheet.

[0103] Specifically, blank steel sheet is placed into cleaning line for cleaning, and at the same time, ferric chloride is added into cleaning line, the acidity of ferric chloride is 1.3-1.35, and the specific gravity of ferric chloride is 1.15-1.32 (SG).

[0104] Therefore, ferric chloride slightly corrodes the surface of blank, and the depth of slight corrosion is 0.01-0.015μm, which can increase the adhesion of ink on the surface of blank.

[0105] At the same time, cleaning line can also clean the oxide layer, oil stains, foreign matters and the like on the surface of blank.

[0106] When the cleaning is completed, the etching density of the surface of the blank should reach 300-400 mesh.

[0107] At the same time, at the end of the cleaning, the ferric trichloride on the surface of the blank should also be cleaned and removed, and the water stains on the surface of the blank should be dried by heating.

[0108] The ink preparation step S103 is to prepare the ink and adjust the ink to the required state.

[0109] Specifically, the ink is prepared in the following proportions: pigment 25-35%, synthetic resin (epoxy / polyester) 45-50%, additives (defoamer, leveling agent) 0.4%-0.8%, and UV monomer 38%-45%.

[0110] When preparing, volume ratio is preferred, and when containing solid components, it can also be converted to weight for preparation.
