Description
Technical Field
[0001] This utility model relates to the field of cooking utensils technology, and in particular to an easy-to-clean cooking container. Background Technology
[0002] In existing technologies, the design of cooking containers has a significant impact on the cooking effect and ease of cleaning. Traditional cooking containers often feature smooth inner walls or surface treatments with micron-level textures and grooves to improve the evenness of heating and the durability of the container. However, this design has revealed some problems in practical applications, particularly regarding container cleaning.
[0003] While micron-level textures and grooves can enhance the surface properties of containers to some extent, such as improving non-stick properties, their tiny size allows food to easily seep into these minute gaps during cooking. Once food residue remains in these hard-to-reach spaces, it is often difficult to remove completely using conventional cleaning methods. This not only increases the difficulty of cleaning but can also become a breeding ground for bacteria, posing a potential threat to food safety. Utility Model Content
[0004] To overcome at least one of the defects described in the prior art, this utility model provides an easy-to-clean cooking container. It solves the problem of food residue, achieving both good cooking performance and significantly improved ease of cleaning.
[0005] The technical solution adopted by this utility model to solve its problem is:
[0006] An easy-to-clean cooking container includes a container body having a receiving groove for holding food. The inner wall of the receiving groove is provided with a plurality of concave patterns, which are sequentially connected to form a textured surface. The textured surface covers at least to the bottom surface of the receiving groove. The depth H of the concave patterns is 0.2 mm to 0.5 mm, and the spacing X between every two patterns ranges from 0.5 mm to 1 mm.
[0007] By employing the above-mentioned solution, a textured surface is created by incorporating centimeter-sized concave patterns on the inner wall. The depth and spacing of these patterns are meticulously calculated to ensure that food does not easily remain inside the texture, while simultaneously achieving excellent non-stick properties through micropores and hardening treatment. This design not only effectively improves the ease of cleaning the cooking container but also maintains excellent cooking results and durability.
[0008] Furthermore, the graphic is one of the following: triangle, sector, pentagon, hexagon, octagon, circle, ellipse, teardrop, rectangle, and rhombus, and the type of graphic within the textured surface is at least one.
[0009] By adopting the above solutions, not only are cooking containers enhanced with aesthetics and personalization options, but more importantly, significant improvements are brought about in terms of cleanliness, cooking performance, and durability. The diverse graphic designs also contribute to improved durability. During long-term use, friction and impact between food and cooking utensils and the container's inner wall are inevitable. By employing graphic designs with various shapes, these forces can be dispersed, reducing wear in individual areas and thus extending the lifespan of the cooking container.
[0010] Furthermore, the patterns within the textured surface are all hexagonal, and the spacing L between two pairs of sides in the pattern is 1mm-3mm.
[0011] By adopting the above solution, the hexagonal design can better distribute heat, ensuring that the food is heated evenly during cooking, avoiding local overheating or insufficient heating, thereby improving the cooking effect and the taste of the food. At the same time, the limited size can prevent food from getting stuck and make it easier to clean the slurry.
[0012] Furthermore, the bottom surface of the pattern is provided with multiple micropores.
[0013] By adopting the above scheme, the purpose of micropores is to increase the friction on the bottom surface of the pattern and achieve good non-stick properties.
[0014] Furthermore, the container body includes a container opening, a container neck, and a container body from top to bottom, the textured surface is located on the inner side of the container body, and the area of the textured surface is not less than half of the inner area of the container body.
[0015] By adopting the above method, because the textured surface occupies a large area of the container's inner side, the food can be more evenly heated during cooking, thus avoiding localized overheating or underheating. This helps improve the cooking results and the taste of the food.
[0016] Furthermore, the inner diameter of the container neck is smaller than the inner diameter of the container opening, and the outer diameter of the container opening is larger than the outer diameter of the container body.
[0017] By adopting the above design, the container becomes more stable when pouring food or liquids, reducing the likelihood of spillage due to shaking. Simultaneously, the smaller container neck allows for more controllable pouring flow, enabling users to precisely control the amount poured. During cooking or heating, food or liquids may overflow due to expansion or boiling. The container neck design reduces the possibility of such overflows, ensuring that food and liquids remain inside the container, thus maintaining a clean and safe cooking environment.
[0018] Furthermore, the container body is a single-layer iron plate, which is a cold-rolled iron plate or a galvanized iron plate.
[0019] By employing the above methods, both cold-rolled iron sheets and galvanized iron sheets possess excellent thermal conductivity, enabling them to quickly and evenly transfer heat from the heat source to the food. This helps ensure that the food is heated evenly during cooking, improving cooking results and the taste of the food.
[0020] Furthermore, the container body is a composite plate, and the composite plate includes, along its thickness direction, a first stainless steel layer, a metal layer, and a second stainless steel layer in sequence.
[0021] By adopting the above scheme, the first stainless steel layer and the second stainless steel layer serve as the inner and outer surface layers of the composite plate, which can effectively resist oxidation, corrosion and stains. The metal layer located between the two stainless steel layers has excellent thermal conductivity and mechanical strength, which not only enhances the overall structural strength of the composite plate, but also improves the corrosion resistance of the container, because the metal layer can prevent the stainless steel layer from being damaged by direct exposure to harsh environments.
[0022] Furthermore, the arrangement of multiple patterns in the textured surface can be a circular array, a radial array, or a transverse array.
[0023] By adopting the above scheme, the ring array pattern is evenly distributed in a circular shape with the center as the center. This arrangement ensures a more even distribution of heat inside the container, reducing hot and cold spots during cooking and making the food heat more evenly. The radial array pattern is arranged radially outward from the center. This design helps heat spread evenly from the center to the surroundings, also achieving a uniform heating effect. The horizontal array pattern is evenly arranged horizontally inside the container. This arrangement ensures that the food is heated evenly in the horizontal direction during frying and stir-frying.
[0024] Furthermore, the graphic has protruding bumps, the height of which is consistent with the depth of the recess in the graphic.
[0025] By adopting the above solution, the raised dot design can further prevent food such as rice grains from getting stuck in the recesses of the graphic, thus improving the non-stick effect.
[0026] In summary, the easy-to-clean cooking container provided by this utility model has the following technical effects:
[0027] 1. By creating a textured surface through recessed patterns of specific depth and spacing on the inner wall, this design effectively reduces the likelihood of food seeping into the tiny gaps in the container's inner wall during cooking. Food is also more easily removed from the container's inner wall during cooking and cleaning, thus significantly reducing the risk of food residue.
[0028] 2. The recesses and gaps in the pattern are not at the micrometer level, allowing conventional cleaning tools to more easily reach and remove residues inside the texture. This greatly simplifies the cleaning process and improves cleaning efficiency;
[0029] 3. The concave design helps distribute heat evenly along the inner wall of the container. During cooking, heat can be transferred more evenly to the food, ensuring even heating and improving cooking results. Attached Figure Description

[0038] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.
[0039] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.
[0040] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0042] See Embodiment 1 of this utility model. Figures 1-5 As shown, an easy-to-clean cooking container is disclosed, including a container body formed by stretching a single layer of iron plate or multiple layers of plate. The container body has a receiving groove 11 for holding food. The inner wall of the receiving groove 11 is provided with a plurality of concave patterns 21. The patterns 21 are connected in sequence to form a textured surface 2. The patterns 21 can be formed by etching or embossing, which is not specifically limited in this embodiment. The textured surface 2 covers at least to the bottom surface of the receiving groove 11. The depth H of the concave patterns 21 is 0.2mm to 0.5mm, and the spacing X between every two patterns 21 ranges from 0.5mm to 1mm. By setting concave patterns 21 with centimeter-sized dimensions on the inner wall, the textured surface 2 is formed. The depth and spacing of these patterns 21 are carefully calculated to ensure that food is not easily retained inside the texture, while achieving good non-stick properties through micropores and hardening treatment. This design not only effectively improves the ease of cleaning the cooking container, but also maintains excellent cooking performance and durability.
[0043] It should be noted that the single-layer iron plate is preferably a cold-rolled iron plate or a galvanized iron plate. Both cold-rolled and galvanized iron plates have good thermal conductivity, enabling them to quickly and evenly transfer heat from the heat source to the food. This helps ensure that the food is heated evenly during cooking, improving the cooking effect and the taste of the food. The composite plate includes, along its thickness direction, a first stainless steel layer, a metal layer, and a second stainless steel layer. Preferably, the metal layer is made of copper or aluminum, which have good thermal conductivity. The first and second stainless steel layers, as the inner and outer surface layers of the composite plate, can effectively resist oxidation, corrosion, and stains. The metal layer located between the two stainless steel layers has excellent thermal conductivity and mechanical strength, which not only enhances the overall structural strength of the composite plate but also improves the corrosion resistance of the container, because the metal layer can prevent the stainless steel layer from being damaged by direct exposure to harsh environments.
[0044] In some embodiments, optionally, the pattern 21 is one of a triangle, sector, pentagon, hexagon, octagon, circle, ellipse, teardrop, rectangle, or rhombus, and the pattern 21 within the textured surface 2 is of at least one type. This not only adds aesthetic appeal and personalization to the cooking container but, more importantly, significantly improves cleanliness, cooking performance, and durability. The diverse pattern 21 design also helps improve the durability of the cooking container. During long-term use, friction and collision between food and cooking tools and the inner wall of the container are inevitable. By employing a variety of pattern 21 shapes, these forces can be dispersed, reducing wear in individual areas and thus extending the lifespan of the cooking container. In this embodiment 1, see... Figure 4 As shown, the patterns 21 within the textured surface 2 are all hexagons, and the distribution is uniformly filled. The spacing L between two pairs of sides in the pattern 21 is 1mm-3mm. The hexagonal design can better distribute heat, ensuring that the food is heated evenly during cooking, avoiding local overheating or insufficient heating, thereby improving the cooking effect and the taste of the food. At the same time, the limited size can prevent food from getting stuck and facilitate the cleaning of the slurry.
[0045] Specifically, in this embodiment 1, refer to Figure 2 As shown, the container body includes, from top to bottom, a container opening 12, a container neck 13, and a container body 14. The textured surface 2 is located inside the container body 14, and the area of the textured surface 2 is not less than half of the area of the inner side of the container body 14. In some embodiments, the area of the textured surface 2 is half of the area of the inner side of the container body 14. In some embodiments, see [reference needed]. Figure 6-7As shown, the textured surface 2 covers the entire inner side of the container body 14. Because the textured surface 2 occupies a large area of the inner side of the container body 14, the food can be heated more evenly during cooking, thus avoiding localized overheating or underheating. This helps improve the cooking effect and the taste of the food.
[0046] For a better option, see [link / reference]. Figure 2 As shown, the inner diameter of the container neck 13 is smaller than the inner diameter of the container opening 12, and the outer diameter of the container opening 12 is larger than the outer diameter of the container body 14. This design makes the container more stable when pouring food or liquids, and less prone to splashing due to shaking. At the same time, the smaller container neck 13 also makes the pouring flow more controllable, allowing users to precisely control the amount poured. During cooking or heating, food or liquids may overflow due to expansion or boiling. The design of the container neck 13 reduces the possibility of such overflow, ensuring that food and liquids remain inside the container, thereby maintaining a clean and safe cooking environment.
[0047] In some embodiments, to improve the non-stick properties of the container body, a plurality of micropores are provided on the bottom surface of the pattern 21. The micropores are very small and usually invisible to the naked eye. Their purpose is to increase the friction of the bottom surface of the pattern 21 and achieve good non-stick properties.
[0048] In some embodiments, see Figure 4 As shown, to improve the non-stick performance of the container body, protruding bumps 3 can be provided within the pattern 21. The height of the bumps 3 is consistent with the depth of the recess in the pattern 21. The bumps 3 are preferably circular. Taking the hexagonal recess in the pattern 21 of this embodiment as an example, the bump 3 is located in the center of the hexagon. The width of the hexagon is 5mm, the depth is 0.5mm, and the diameter D of the bump 3 is 1mm. The design of the bumps 3 can further prevent food such as rice grains from getting stuck in the recess of the pattern 21, improving the non-stick effect. (See reference...) Figure 5 As shown, the food ingredient is rice grains 4. The rice grains 4 cannot enter the recess of the graphic 21, and the protrusion 3 will also abut against the rice grains 4, thus achieving the anti-stick effect.
[0049] It should be noted that, in other embodiments, the arrangement of the multiple patterns 21 in the textured surface 2 can be, but is not limited to, a circular array, a radial array, or a transverse array. In a circular array, the patterns 21 are evenly distributed in a ring shape with the center as the center. This arrangement ensures a more uniform heat distribution inside the container, reducing hot and cold spots during cooking and resulting in more consistent heating of the food. In a radial array, the patterns 21 are arranged radially outward from the center. This design helps heat diffuse evenly from the center outwards, also achieving uniform heating. In a transverse array, the patterns 21 are evenly arranged horizontally inside the container. This arrangement ensures that the food is heated evenly in the horizontal direction during frying or stir-frying.
[0050] Optionally, in some embodiments, a protective film can be sprayed onto the textured surface 2. The protective film is preferably a silica film, which can provide good anti-friction properties and effectively reduce the wear of the textured surface 2.
[0051] In summary, the easy-to-clean cooking container provided by this utility model has the following technical effects:
[0052] 1. By creating concave patterns 21 of specific depth and spacing on the inner wall, a textured surface 2 is formed. This design effectively reduces the possibility of food seeping into the tiny gaps in the container's inner wall during cooking. Food is more easily removed from the container's inner wall during cooking and cleaning, thus significantly reducing the risk of food residue.
[0053] 2. The recesses and gaps in pattern 21 are all non-micron-level, allowing conventional cleaning tools to more easily reach and remove residues inside the texture. This greatly simplifies the cleaning process and improves cleaning efficiency;
[0054] 3. The concave graphic design helps to distribute heat evenly on the inner wall of the container. During cooking, heat can be transferred to the food more evenly, thus ensuring that the food is heated evenly and improving the cooking effect.
[0055] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
