Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a non-stick pot and a cooking utensil. Background Art

[0002] Existing cooking utensils such as electric rice cookers usually have a pot inside, and rice and other ingredients are cooked inside the pot. During the cooking process, the ingredients may stick to the inner wall of the pot, making the pot difficult to clean and causing food waste. The common method to solve the sticking phenomenon is to set a non-stick coating on the inner wall of the pot, but the non-stick coating is easy to fall off due to scratches during use, affecting the anti-stick effect and contaminating the ingredients. For this reason, the pot is also provided with a concave-convex structure, and the non-stick coating is arranged in the concave part to prevent tools such as shovels from scratching the non-stick coating.

[0003] Therefore, a non-stick pot and a cooking utensil are needed to at least partially solve the above problems. Utility Model Content

[0004] The content of the utility model introduces a series of simplified concepts, which will be further described in detail in the detailed implementation section. The content of the utility model does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

[0005] In order to at least partially solve the above problems, the utility model provides a non-stick pot, the non-stick pot comprises a pot base, the inner surface of the pot base is formed with concave and convex non-stick textures, the non-stick textures are arranged in a continuous grid, the non-stick textures include a plurality of texture units, and the texture units include:

[0006] at least two graphic elements, the at least two graphic elements are arranged at intervals and have two or more shapes and / or arrangements; and

[0007] continuous mesh elements, wherein the mesh elements are formed between adjacent graphic elements,

[0008] The graphic elements and the textured elements are convex and / or concave patterns arranged on the inner surface, the pot base has a maximum latitudinal diameter, and the area where the non-stick patterns are arranged is located below the position of the maximum latitudinal diameter of the pot base.

[0009] According to this solution, a pot without a non-stick coating is provided; the non-stick cavity formed by the concave pattern of the non-stick pattern can accumulate condensed water. After the food is cooked, the pot starts to cool down from the outside to the inside, so that the water vapor in the pot is condensed into small water droplets on the inner surface of the pot and gathered in the non-stick cavity. These small amounts of condensed water are in the form of continuous veins, which reduces the adhesion between the food and the inner surface of the pot, thereby achieving a non-stick effect.

[0010] After the ingredients are cooked, generally speaking, the surface of the pot below the waist, especially the bottom of the pot, is most likely to stick to the pot. In this solution, the non-stick pattern is arranged below the position of the maximum latitudinal diameter of the pot base. This area makes it easier for condensed water to gather in the concave pattern along the inner wall of the pot, thereby specifically focusing on solving the problem of the entire pot of ingredients sticking to the pot, while reducing the process difficulty and corresponding cost of manufacturing the non-stick pattern on the pot.

[0011] Furthermore, the shape and / or arrangement of the graphic elements of this solution are continuous and diverse. The condensed water formed by the steam on the inner surface of the pot can spread along the continuous texture to reduce the sticking phenomenon of the bottom of the whole pot of rice, and the non-stick effect is better. The non-stick performance of the pot without non-stick coating is further improved. In addition, the continuous grid-like arrangement of non-stick patterns makes the structure of the inner surface of the pot more visible, which enhances the visual experience of the product.

[0017] According to this solution, the area occupied by the non-stick pattern on the inner pot is more appropriate and not too small, so the problem of food sticking to the pot can be solved in a targeted manner, and the food sticking to the bottom of the pot where the sticking phenomenon is more obvious can be effectively avoided.

[0018] Optionally, the interior of the non-stick pot is provided with a pattern for providing instructions to the user, and the area where the non-stick lines are provided is located below the bottom of the pattern.

[0024] Optionally, at least two adjacent graphic elements have the same shape and more than two arrangements.

[0033] Optionally, the texture elements are used to form concave patterns of the non-stick pattern, and the graphic elements are used to form convex patterns of the non-stick pattern.

[0075] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0076] The utility model provides a cooking utensil, which comprises a pot body and a cover body. The pot body has a cylindrical pot inner storage portion. The pot inner can be fixedly arranged at the pot inner storage portion, or can be freely placed in the pot inner storage portion or taken out from the pot inner storage portion to facilitate the cleaning of the pot inner. The pot inner is usually made of metal material and has a circular opening on the upper surface for holding materials to be heated, such as rice, soup, etc. The pot body includes a heating device for heating the pot inner, such as a heating plate, to heat the pot inner.

[0077] It can be understood that the cooking utensil according to the present invention can be an electric rice cooker, an electric pressure cooker or other cooking utensil, and the cooking utensil can have various functions such as cooking porridge in addition to the function of cooking rice.

[0078] The cover has a shape that is substantially the same as that of the pot body. The cover can be opened and closed on the pot body. Specifically, the cover is pivotally connected to the pot body via a pivot shaft and can freely pivot between a closed position and an open position relative to the pot body around a pivot axis where the pivot shaft is located, so as to facilitate closing and opening the pot body. When the cover is closed on the pot body, it covers the inner pot and forms a cooking space between the inner pot and the inner pot. The cover is usually also provided with a pot mouth sealing ring, which can be made of, for example, a rubber material, and is arranged between the cover and the inner pot to seal the cooking space when the cover is in the closed state.

[0079] In order to solve the problem of sticking to the pan, Figures 1 to 6 As shown, the utility model provides a non-stick pot 1. The pot 1 has no non-stick coating, but achieves non-stick performance through the structure of the inner wall of the pot 1. The non-stick pot 1 includes a pot base 10. The inner surface of the pot base 10 is formed with concave and convex non-stick patterns 20, such as Figure 2 As shown, the non-stick pattern 20 is arranged in a continuous grid. The non-stick pattern 20 is composed of a plurality of graphic elements 22 and a continuous mesh pattern 24. The inner surface of the pot base 10 is the innermost surface of the pot 1. Further, there is no other coating on the inner side of the pot base 10, thereby providing a zero-coating pot 1.

[0080] The non-stick pattern 20 is formed on a stainless steel substrate. One example is that the pot substrate 10 is constructed as a single-layer structure and is made of stainless steel. In this solution, the pot substrate 10 is a stainless steel substrate. Another example is that the pot substrate 10 is constructed as a two-layer or more structure and at least the innermost layer of the pot substrate 10 is made of stainless steel. In this solution, the pot substrate 10 has a stainless steel base layer located in the innermost layer. The non-stick pattern 20 can be formed by etching on a stainless steel substrate, and then the stainless steel substrate with the non-stick pattern 20 is formed into a pot 1; it can also be formed by etching on the formed pot substrate 10. In addition to etching, other processes such as mechanical embossing and photolithography can also be used, which are not limited in this article. The stainless steel material is food grade, and the product is safer and healthier to use.

[0081] Specifically, Figure 2 As shown, the non-stick pattern 20 includes a plurality of texture units 21, and the portion between adjacent texture units 21 is used to form a reticulation 24. It should be noted that the "texture unit" herein has the following meanings: the texture unit 21 is the smallest repeating unit selected from the non-stick pattern 20, and all texture units 21 in the non-stick pattern 20 are identical in shape, size, arrangement and other elements, and have the characteristics of repeatability, continuous arrangement, and infinite spread. Furthermore, the texture unit 21 is repeatable in production and manufacturing. The reticulation extends continuously inside the texture unit 21 and around the outside of the texture unit 21. The reticulation extending continuously inside the texture unit 21 serves as a constituent element of the texture unit 21, namely, the reticulation element 23, and separates the texture unit 21 into a plurality of graphic elements 22. The graphic element 22 is a single graphic with a closed outline.

[0082] Figure 3 A texture unit 21 is schematically shown, as shown in FIG. Figure 3 As shown, the texture unit 21 includes at least two graphic elements 22 and continuous mesh elements 23, at least two graphic elements 22 are arranged at intervals, and the mesh elements 23 are formed between adjacent graphic elements 22. Further, the mesh elements 23 are adjacent to the graphic elements 22, or connected, or have the same border; adjacent graphic elements 22 are separated by the mesh elements 23. One of the graphic elements 22 and the mesh elements 23 is used to form the concave pattern 26 of the non-stick pattern 20, and the other of the graphic elements 22 and the mesh elements 23 is used to form the convex pattern 25 of the non-stick pattern 20. And the concave pattern 26 is distributed in a continuous grid shape.

[0083] At least two graphic elements 22 have more than two shapes and / or arrangements. In one aspect: one example is that the shapes of at least two graphic elements 22 are all different; another example is that when there are at least three graphic elements 22, the shapes of at least three graphic elements 22 are partially different. In these two examples, the arrangements of the graphic elements 22 may be all the same, partially different, or all different. In another aspect: one example is that the arrangements of at least two graphic elements 22 are all different; another example is that when there are at least three graphic elements 22, the arrangements of at least three graphic elements 22 are partially different. In these two examples, the shapes of the graphic elements 22 may be all the same, partially different, or all different.

[0084] In this embodiment, the non-stick pattern 20 can provide a good non-stick effect for food materials whose molecules contain hydrogen bonds, such as starch (rice), protein (eggs) and other types of food materials during high-temperature cooking. The grooves 26 of the non-stick pattern 20 form an anti-stick cavity, which can reduce the contact area between the food materials and the inner surface of the pot 1, thereby reducing the adhesion between the food materials and the inner surface of the pot 1. Compared with the smooth inner surface, the geometric structure of the inner wall of the pot 1 can play a non-stick role, so that the pot 1 has non-stick properties to avoid sticking. This embodiment achieves non-stick properties through the geometric structure of the inner wall of the pot 1, which can avoid the provision of a non-stick coating, thereby avoiding the contamination of food materials due to the shedding of the non-stick coating, thereby improving the reliability of the product and the user's cooking experience.

[0085] Furthermore, the anti-sticking cavity formed by the grooves 26 can also accumulate condensed water. After the food is cooked, the pot 1 starts to cool down from the outside to the inside, so that the water vapor in the pot 1 is condensed into tiny water droplets on the inner surface of the pot and gathered in the anti-sticking cavity. These small amounts of condensed water are in the form of continuous veins, which reduces the adhesion between the food and the inner surface of the pot 1. The non-stick performance of the pot 1 without a non-stick coating is further improved.

[0086] Furthermore, the shape and / or arrangement of the graphic elements 22 of the present solution are continuous and diverse. The condensed water formed by the steam on the inner surface of the pot can spread along the continuous texture to reduce the sticking phenomenon of the bottom of the whole pot of food, and the non-stick effect is better. The non-stick performance of the pot 1 without a non-stick coating is further improved. In addition, the continuous grid-like arrangement of non-stick patterns makes the structure of the inner surface of the pot 1 more visible, which enhances the visual experience of the product.

[0087] like Figure 1 As shown, the pan base 10 has a maximum latitudinal diameter d1, and the area R where the non-stick pattern 20 is located is located below the position A where the maximum latitudinal diameter of the pan base 10 is located. It should be noted that the maximum latitudinal diameter is the diameter extending in a direction parallel to the horizontal plane. Figure 1As shown, the area R where the non-stick pattern 20 is provided is schematically shown by hatching. After cooking of food such as rice, in general, the surface of the pot below the waist of the pot 1, especially the bottom of the pot, is most likely to stick to the pot. In this solution, the non-stick pattern 20 is provided below the position of the maximum latitudinal diameter of the pot base 10. This area is more likely to allow condensed water to gather in the concave pattern 26 along the inner wall of the pot 1, and the problem of the whole pot of food sticking to the pot is targeted and focused on, while reducing the process difficulty and corresponding cost of manufacturing the non-stick pattern on the pot.

[0088] Specifically, the pot base 10 includes a bottom wall 11, a transition section 12 and a side wall 13, wherein the maximum latitudinal diameter is formed on the side wall 13, and at least the transition section 12 is an arc-shaped structure. Figure 1 As shown, the bottom wall 11, the transition section 12 and the side wall 13 are all arc-shaped structures, and the boundaries between the three are not obvious. The transition section 12 includes the position with the steepest slope. Figure 1 The position of the transition section 12 is schematically indicated, and the position A where the maximum latitudinal diameter of the pot base 10 is located corresponds to the maximum latitudinal diameter of the spherical kettle. For an ordinary pot, the side wall 13 and the bottom wall 11 are straight wall structures, sometimes with arc-shaped parts; the transition section 12 is an arc-shaped structure. The position A where the maximum latitudinal diameter of the pot base 10 is located corresponds to the bottom end of the side wall 13 of an ordinary pot. It should be noted that the "arc-shaped structure" here means an arc-shaped structure in a vertical section.

[0089] The non-stick pattern 20 is provided on the bottom wall 11 and at least a part of the transition section 12. Such a setting is a better choice for the comprehensive balance between the difficulty of manufacturing the non-stick pattern 20 and the non-sticking of the food such as rice in the pot 11. Because the heating device will heat the bottom of the pot 11 with a high fire, the sticking phenomenon of the pot 11 at the bottom will be more obvious, so the non-stick pattern 20 is preferably completely covered on the bottom wall 11 of the pot base 10, so as to effectively avoid the sticking phenomenon of the food. A water level line 15 is provided inside the non-stick pot 1, and the area R where the non-stick pattern 20 is provided is located below the bottom of the water level line 15. The setting area of ​​the water level line 15 does not overlap with the area R where the non-stick pattern 20 is provided, and the non-stick pattern 20 will not interfere with the user's observation of the water level line 15. The water level line 15 is clearly distinguishable, so the user's use experience can be improved.

[0090] The height of the pot 1 is H; the distance from the area R where the non-stick pattern 20 is set to the pot edge is H1, the distance to the position A where the maximum latitudinal diameter is located is H2, and the distance to the bottom of the water level line 15 is H3. The height relationship thus exists is H>H1>H2>H3>0. The projection of the area R where the non-stick pattern 20 is set on the horizontal plane has a diameter d2, where d1>d2>1 / 2d1. The area occupied by the non-stick pattern 20 on the pot 1 is more suitable and not too small, which can effectively prevent the food from sticking to the bottom of the pot 1 where the sticking phenomenon is more obvious.

[0091] In one embodiment, the non-stick pot 1 is provided with a pattern 14 for providing instructions to the user, and the area R where the non-stick pattern 20 is provided is located below the bottom of the pattern 14. The pattern 14 includes the water level line 15 and / or the product logo 18 mentioned above. Figure 1 It is shown that the pattern 14 includes a water level line 15 and a product logo 18. The water level line 15 includes various water level lines according to different ingredients and different cooking conditions, such as a water level line 16 for cooking rice, which includes at least one water level scale for rice, and a water level line 16 for cooking porridge and rice porridge, which includes a water level scale indicating cooking porridge and a water level scale indicating cooking porridge. The product logo 18 may include information such as product material. The pattern 14 may be formed by laser engraving. In addition to laser engraving, other processes may also be used, such as etching, mechanical embossing, and photolithography, which are not limited herein.

[0092] The graphic element 22 may be a polygon, such as a triangle, a quadrilateral or a pentagon, etc.; the sides of the polygon are straight sides and / or curved sides. It should be noted that the illustrated embodiment schematically shows the planar structure of the non-stick pattern 20 and the texture unit 21. However, the inner surface of the pot 1 is not a plane, and the graphic element 22 needs to be adjusted to the shape of the inner surface of the pot 1, so that the sides of some graphic elements 22 are configured as straight sides, and the sides of some graphic elements 22 are configured as curved sides. Of course, if necessary and / or desired, in the case of partial adaptation to the shape of the inner surface of the pot 1, the sides of all graphic elements 22 are configured as straight sides and / or curved sides. The graphic element 22 is selected as a polygon, and the spacing between adjacent polygons at each position can be arranged smaller, so that a reticulation 24 with a smaller width can be provided, which is conducive to a smaller density design of the reticulation 24; and it is convenient to provide neatly arranged non-stick patterns 20, which is convenient for production and manufacturing.

[0093] Optionally, at least two graphic elements 22 have the same shape and more than two arrangements. Select graphic elements 22 of the same shape, and adjust the arrangement to form a texture unit 21; such an arrangement is conducive to ensuring that the texture unit 21 provides a uniform support effect and non-stick effect at each graphic element 22 and its adjacent mesh 24, thereby improving the non-stick performance of the pot 1 as a whole; and can simplify the structure of the texture unit 21, thereby simplifying the structure of the non-stick pattern 20, which is convenient for production and manufacturing. For example, all graphic elements 22 of the texture unit 21 are triangles, quadrilaterals or pentagons. Taking the illustrated embodiment as an example, the texture unit 21 includes three graphic elements 22 and a continuous mesh element 23; these three graphic elements 22 are quadrilaterals of the same shape, and the arrangement of the three graphic elements 22 is different, that is, there are three arrangements. Specifically, the three graphic elements 22 are all rhombuses, one graphic element 22 is arranged vertically; two graphic elements 22 are arranged obliquely, with different inclination directions and the same inclination angle.

[0094] Furthermore, the texture unit 21 can form a polygonal pattern. More specifically, the outer edge contour of the texture unit 21 is polygonal in shape. The continuous mesh elements separate the texture unit 21 into a plurality of graphic elements 22, so that the texture unit 21 as a whole is a pattern in shape; hence, it is called a polygonal pattern. Optionally, the texture unit 21 can form a polygonal pattern with an even number of sides. The polygonal pattern can be an irregular polygon or a regular polygon with an even number of sides, such as an irregular hexagon or a regular hexagon. The texture unit 21 can be an axisymmetric figure, Figure 3 The texture unit 21 shown has a center line extending along the first direction D1 and passing through the texture unit 21 in the second direction D2. This arrangement facilitates the neat arrangement of the texture units 21 to form a regular mesh 24 and a regular non-stick pattern 20, thereby facilitating production.

[0095] Optionally, the mesh elements 23 are used to form the concave patterns 26 of the non-stick pattern 20, and the graphic elements 22 are used to form the convex patterns 25 of the non-stick pattern 20. With such a configuration, in production and manufacturing, the mesh elements 23 are more likely to form the concave patterns 26 distributed in a continuous grid shape; and the mesh elements 23 can be easily configured to provide anti-sticking cavities with a more suitable size, which is conducive to the condensed water being in a continuous vein shape. In this way, the non-stick ability of the non-stick pattern 20 as a whole can be improved, and the non-stick performance of the pot 1 is more superior.

[0096] The concave pattern 26 can be recessed from the inner surface of the pot base 10, and the inner surface of the pot base 10 is surrounded by the concave pattern 26 to form the convex pattern 25. The concave pattern 26 and the convex pattern 25 can be directly formed based on the pot base 10, and the production process is simple and convenient for production and manufacturing. Alternatively, a mesh member with mesh holes can be attached to the inner surface of the pot base 10, wherein the hole wall of the mesh hole and the inner surface of the pot base 10 in the mesh hole constitute the concave pattern 26, and the mesh member protrudes from the inner surface of the pot base 10, so as to constitute the convex pattern 25. The alternative scheme is applicable to the embodiment in which the mesh element 23 constitutes the convex pattern 25.

[0097] The graphic element 22 has a sharp corner. The sharp corner is a bad corner. The local concave and convex sharp corners can split the thin starch layer formed by the food to destroy the adhesion of the food, which is conducive to the food being quickly separated from the inner surface of the pot 1 due to being split; and because the concave and convex at the sharp corners are more obvious, the adhesion between the food and the inner surface of the pot 1 can be more significantly reduced, effectively improving the non-stick performance of the pot 1. For example, during the cooking process, rice is deposited on the bottom of the pot 1 to produce a thin starch layer. When the user scoops the rice from the pot 1, all the sharp corners in the scooping area will have a tearing and splitting effect on the thin starch layer. Optionally, see Figure 2, the angle α of the sharp angle is 15°≤α≤90°; for example, α can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°,

[0098] Suitable angle values ​​include 85°, 90°, etc. Optionally, 15°≤α<90°.

[0099] The depth T of the recessed grooves 26 relative to the raised grooves 25 (see Figure 6 ) is 0.01mm≤T≤0.5mm; for example, the recess depth T can be 0.01mm, 0.02mm, 0.05mm, 0.08mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm,

[0100] 0.4mm, 0.45mm, 0.5mm and other suitable values. The depth of the groove 26 is related to the thickness of the inner pot 1. Generally, the greater the thickness of the inner pot 1, the deeper the depth of the groove 26. The spacing D between adjacent graphic elements 22 is 0.2mm≤D≤2mm; for example, the spacing D can be 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.0mm and other suitable values. It should be noted that the spacing D between adjacent graphic elements 22 does not specifically refer to the maximum spacing and the minimum spacing, but the spacing between the edges at various positions. For example, the edge of a graphic element 22 has positions P1 and P2, and the spacing between position P1 and the edge of another graphic element 22 is within the above-defined D range, and the spacing between position P2 and the edge of another graphic element 22 is also within the above-defined D range.

[0101] The texture unit 21 has a first direction D1 and a second direction D2 perpendicular to the first direction D1. The first sub-dimension L11 of the graphic element 22 in the first direction D1 is 1mm≤L11≤15mm; for example, the first sub-dimension L11 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm and other suitable values. The second sub-dimension L12 of the graphic element 22 in the second direction D2 is 0.5mm≤L12≤15mm; for example, the second sub-dimension L12 can be 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm,

[0102] Suitable values ​​include 11mm, 12mm, 13mm, 14mm, 15mm, etc.

[0103] like Figure 3As shown, the first main dimension L21 of all graphic elements 22 of the texture unit 21 in the first direction D1 is 2 mm ≤ L21 ≤ 20 mm; for example, the first main dimension L21 can be 2 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm,

[0104] The second main dimension L22 of all graphic elements 22 of the texture unit 21 in the second direction D2 is 2mm≤L22≤20mm; for example, the second main dimension L22 can be 2mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, etc.

[0105] A texture collection 30 can be selected from the non-stick texture 20, and the size of the texture collection 30 can be limited to assist in the processing and manufacturing of the non-stick texture 20 of the pot 1. Figure 4 As shown, for the illustrated embodiment, it can be obtained from Figure 2 A texture collection 30 constituting a star pattern is selected from the above. A first reference dimension L31 of the star pattern in the first direction D1 is 3 mm ≤ L31 ≤ 40 mm; for example, the first reference dimension L31 may be a suitable value such as 3 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, etc. A second reference dimension L32 of all graphic elements 22 of the texture unit 21 in the second direction D2 is 5 mm ≤ L32 ≤ 40 mm; for example, the second reference dimension L32 may be a suitable value such as 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, etc.

[0106] Figure 5 and Figure 6 The structure of the inner pot 1 in use is schematically shown, wherein rice grains are schematically shown. Taking rice grains 2 as an example, illustratively, the width of a single concave pattern 26 (i.e., the spacing between adjacent convex patterns 25) is smaller than the particle size of the rice grains 2, and the lateral dimension of a single convex pattern 25 is smaller than the particle size of the rice grains 2. For the illustrated embodiment, the mesh elements 23 constitute the concave patterns 26, and the graphic elements 22 constitute the convex patterns 25, thereby, the spacing D between adjacent graphic elements 22 can be selected to be smaller than the particle size of the rice grains 2, and the second sub-dimension L12 of the graphic elements 22 in the second direction D2 can be selected to be smaller than the particle size of the rice grains 2. The rice grains 2 can cross the single concave patterns 26 and the single convex patterns 25, thereby, the convex patterns 25 can provide support to the rice grains 2, and the concave patterns 26 can reduce the contact area between the rice grains 2 and the inner surface of the pot base 10, and accumulate condensed water, thereby reducing the adhesion between the food and the inner surface of the inner pot 1; thus, the problem of sticking to the pot is effectively solved.

[0107] In other alternatives, if necessary and / or desired, a portion of the graphic elements 22 may constitute the concave pattern 26, and another portion thereof may constitute the convex pattern 25; a portion of the mesh elements 23 may constitute the concave pattern 26, and another portion thereof may constitute the convex pattern 25, so as to form the concave pattern 26 distributed in a continuous grid. If necessary and / or desired, other elements, such as straight line elements, curved line elements, etc., may exist between the graphic elements 22 and the mesh elements 23, so as to form the concave pattern 26 distributed in a continuous grid.
