Description

Technical Field

[0001] This utility model relates to the technical field of food preparation cup components, specifically to a food preparation cup component and a food processor. Background Technology

[0002] Food processors such as blenders, juicers, and soy milk makers typically include a blending cup assembly. This assembly comprises a blending cup and a blending / grinding blade located within it. The blade blends and pulverizes the ingredients within the blending chamber to achieve food processing. However, the blending / grinding blades in these technologies suffer from low pulverization efficiency, generate numerous air bubbles during the pulverization process, and produce significant noise. Utility Model Content

[0003] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In related technologies, the cross-sectional profile of the cooking chamber in a blender cup is typically circular. To improve mixing and pulverizing effects, baffles are usually incorporated into the inner wall of the cooking chamber. However, the size of these baffles is limited by the distance between the distal end of the blending blade and the inner wall of the cooking chamber, thus hindering the achievement of optimal turbulence. Furthermore, since the distance between the distal end of the blending blade and the inner wall of the cooking chamber is constant, the improvement in mixing and pulverizing effects is limited even with baffles.

[0005] Based on the inventor's above-mentioned findings and understanding, the inventor discovered through research that by setting the outer contour of the cross-section of the cooking cavity to a polygon, the distance between different positions of the inner wall of the cooking cavity and the center of the cooking cavity is not equal. For example, the distance between the corners of the cooking cavity and the center of the cooking cavity is larger. As a result, when the food-water mixture rotates centrifugally along the inner wall of the cooking cavity, it will be partially blocked by the cup wall, resulting in a large change in speed and flow direction, thus achieving effective turbulence of the food-water mixture.

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, embodiments of this utility model propose a cooking cup assembly with good turbulence effect and high pulverization efficiency.

[0008] The food processor assembly of this utility model includes a food processor cup and a blending / grinding blade. The food processor cup has a food processing cavity, the cross-sectional outline of which is generally a regular polygon. The sides of the regular polygon are straight segments or arc segments protruding outward from the center of the food processing cavity, and adjacent sides are directly connected or connected through transition segments. A baffle is provided at the corner of the food processing cavity. The blending / grinding blade includes a mounting part and a blade. The blade includes a first blade, the proximal end of which is connected to the mounting part, and the distal end of which extends in a direction away from the mounting part. The first blade includes an upwardly inclined blade and a downwardly inclined blade. The upwardly inclined blade is inclined upward relative to the mounting part, and the downwardly inclined blade is inclined downward relative to the mounting part. In a plane orthogonal to the rotation axis of the blade, the distance between the distal end of the downwardly inclined blade and the baffle is E, and the distance between the distal end of the upwardly inclined blade and the baffle is F, where 13.3mm≤E≤32.1mm, and / or 13.3mm≤F≤32.1mm.

[0009] The cooking cup assembly of this utility model has a generally regular polygonal cross-sectional profile for the cooking cavity, resulting in varying distances between different positions on the inner wall of the cooking cavity and its center. Furthermore, by setting baffles at the corners of the cooking cavity, when food undergoes centrifugal motion along the inner wall of the cooking cavity under the agitation of the mixing blades, it will be blocked by the baffles when flowing from the center of the side wall of the cooking cavity to the corner, and also blocked by the cup wall when flowing from the corner of the cooking cavity to the center of the side wall. This results in significant changes in speed and flow direction, effectively turbulenting the food and enabling higher pulverization efficiency under the agitation of the mixing blades.

[0010] Furthermore, by using an upper-tilted blade and a lower-tilted blade that are respectively inclined upwards and downwards relative to the mounting portion, and with 13.3mm≤E≤32.1mm and 13.3mm≤F≤32.1mm, the food can be three-dimensionally stirred. This not only avoids the weak stirring force of the first blade on the food near the baffle rib, thus preventing poor food flow and scorching, but also provides the food with a larger stirring space between the baffle rib and the first blade. The food particles are more uniform and have a better taste when stirred by the first blade.

[0011] In some embodiments, 0.85 ≤ F / E ≤ 1.23.

[0012] In this embodiment, the cooking cup assembly is configured such that the cutting radii of the upper and lower inclined blades form a gradient, enabling multi-dimensional cutting of the ingredients. This increases the likelihood of turbulence during ingredient movement, resulting in higher pulverization efficiency, more uniform particle size of the ingredients under the agitation of the first blade, and a better texture.

[0013] In some embodiments, the blade further includes a second blade and a third blade, the proximal ends of the second blade and the third blade being connected to the mounting portion, and the distal ends of the second blade and the third blade extending in a direction away from the mounting portion. In a plane orthogonal to the rotation axis of the blade, the distance between the distal end of the second blade and the baffle is G, and the distance between the distal end of the third blade and the baffle is H, wherein 21mm≤G≤50.6mm, and / or 24.5mm≤H≤55.6mm.

[0014] The food processor assembly in this embodiment features a design that avoids insufficient agitation of ingredients near the turbulence ribs by the mixing blades, thus preventing poor ingredient flow. It also provides greater agitation space between the turbulence ribs and the mixing blades, resulting in more uniform particle size and better texture. Furthermore, the gradient of the cutting radius of the mixing blades enables multi-dimensional cutting of the ingredients, increasing the likelihood of turbulence during ingredient movement and improving pulverization efficiency.

[0015] In some embodiments, the blade further includes a second blade and a third blade, the proximal ends of the second blade and the third blade being connected to the mounting portion. In a plane orthogonal to the rotation axis of the blade, the distance between the distal end of the second blade and the baffle is G, and the distance between the distal end of the third blade and the baffle is H, where 1.05≤G / E≤1.85, and / or 1.28≤H / E≤1.97.

[0016] The food processor assembly in this embodiment features a design that avoids insufficient agitation of ingredients near the turbulence ribs by the mixing blades, thus preventing poor ingredient flow. It also provides greater agitation space between the turbulence ribs and the mixing blades, resulting in more uniform particle size and better texture. Furthermore, the gradient of the cutting radius of the mixing blades enables multi-dimensional cutting of the ingredients, increasing the likelihood of turbulence during ingredient movement and improving pulverization efficiency.

[0017] In some embodiments, in a plane orthogonal to the rotation axis of the blade, the distance between the distal end of the downwardly inclined blade and the center of the sidewall of the cooking cavity is P1, and the distance between the distal end of the upwardly inclined blade and the center of the sidewall is P2, wherein 10.3mm≤P1≤28.1mm and 10.3mm≤P2≤28.1mm.

[0018] In this embodiment, the blending cup assembly, by setting P1≤28.1mm and P2≤28.1mm, avoids the distance between the distal ends of the upward and downward tilting blades and the center of the blending cup sidewall being too small. This prevents food from being squeezed between the downward tilting blade and the cup wall, thus reducing the likelihood of food burning at the bottom. By setting P1≥10.3mm and P2≥10.3mm, it prevents food at corners from being unable to be stirred and thus burning at the bottom. At the same time, the above settings also provide more space for food to be stirred, resulting in more uniform particle size and better texture under the stirring of the upward and downward tilting blades.

[0019] In some embodiments, in a plane orthogonal to the rotation axis of the blade, the distance between the distal end of the downward-inclined blade and the center of the sidewall of the cooking cavity is P1, and the distance between the distal end of the upward-inclined blade and the center of the sidewall of the cooking cavity is P2, wherein 0.85≤P1 / P2≤1.23.

[0020] The cooking cup assembly of this embodiment enables the cutting radii of the upper and lower inclined blades to form a gradient, achieving multi-dimensional cutting of ingredients. This increases the likelihood of turbulence during ingredient movement, resulting in higher pulverization efficiency, more uniform particle size of ingredients under the agitation of the first blade, and better taste.

[0021] In some embodiments, the distance between the distal end of the downward-tilted blade and the bottom wall of the cooking cavity is Q1, and the distance between the distal end of the upward-tilted blade and the bottom wall of the cooking cavity is Q2, wherein 3.5mm≤Q1≤8.6mm, 16.3mm≤Q2≤29.3mm.

[0022] The cooking cup assembly of this embodiment has two advantages. First, it prevents food from getting stuck due to an insufficient gap between the downward-sloping blade and the bottom wall of the cooking chamber, thereby reducing the likelihood that the motor will fail to start due to excessive resistance caused by food getting stuck. Second, it effectively prevents the food at the bottom from being unable to be stirred and lifted due to excessive distance between the downward-sloping blade and the bottom wall of the cooking chamber, which could lead to food burning at the bottom.

[0023] In some embodiments, the ratio of the length of the baffle rib to the depth of the cooking cavity is A, wherein 0.35≤A≤0.8.

[0024] In this embodiment, the food processor cup assembly, by setting A≥0.35, allows the baffle ribs to turbulently move food across a wider area, effectively improving food grinding efficiency. By setting A≤0.8, excessive obstruction of food by the baffle ribs can be avoided, preventing food from splashing and reducing the likelihood of food adhering to the lid and causing waste, while also lowering the cost of the food processor cup.

[0025] In some embodiments, the lower end of the baffle rib is flush with the bottom wall of the cooking cavity; or the lower end of the baffle rib is higher than the bottom wall of the cooking cavity, and the minimum distance between the lower end of the baffle rib and the bottom wall of the cooking cavity is L1, wherein 5mm≤L1≤15.5.

[0026] In this embodiment, the food processor assembly features baffles extending from their lower ends to the bottom wall of the food processing chamber. This design allows food items at the bottom of the chamber to be more easily obstructed by the baffles when passing corners during centrifugal motion, thus altering their flow velocity and direction and improving the overall turbulence effect. Alternatively, by setting L1 ≥ 5mm, denser food items at the bottom of the chamber are effectively prevented from becoming stuck at corners due to the baffles. By setting L1 ≤ 15.5mm, the baffles ensure a good turbulence effect on food items at the bottom of the chamber, thereby improving the food grinding efficiency.

[0027] In some embodiments, the ratio of the sum of the cross-sectional areas of the plurality of the baffles to the minimum cross-sectional area of ​​the cooking cavity is U, wherein 0.0029≤U≤0.0044.

[0028] The food processor assembly in this embodiment, by setting 0.0029≤U≤0.0044, can, on the one hand, achieve turbulence of food in more areas to effectively improve the food crushing efficiency, and on the other hand, avoid excessive obstruction of food by the turbulence ribs, which would cause food to splash and reduce the chance of food adhering to the lid and causing waste. It also reduces the cost of the food processor.

[0029] In some embodiments, the size of the baffle rib protruding toward the center of the cooking cavity is L2, wherein 2.5mm≤L2≤8.5mm.

[0030] The food processor assembly in this embodiment, through the above-described design, allows for better turbulence by the baffle ribs and part of the cup wall when food undergoes centrifugal motion, resulting in higher pulverization efficiency. Furthermore, it reduces the likelihood of food remaining near the baffle ribs, further ensuring optimal pulverization. The resulting particles are more uniform and have a better texture when pulverized by the mixing blades.

[0031] In some embodiments, the cross-sectional profile of the corner is an arc shape with a radius of curvature of R. In a plane orthogonal to the rotation axis of the blade, the maximum distance between the rotation axis of the blade and the cavity wall at the corner is L3, and the distance between the rotation axis and the center of the side wall of the cooking cavity is L4, wherein 0.35≤L2 / L3≤0.8, 0.017≤R / L2≤0.033, and 0.3≤(L3-L4) / L2≤0.75.

[0032] The food processor assembly in this embodiment, through the above-described design, allows for better turbulence by the baffle ribs and part of the cup wall when food undergoes centrifugal motion, resulting in higher pulverization efficiency. Furthermore, it reduces the likelihood of food remaining near the baffle ribs, further ensuring optimal pulverization. The resulting particles are more uniform and have a better texture when pulverized by the mixing blades.

[0033] In some embodiments, the blade further includes a second blade and a third blade, the proximal ends of the second blade and the third blade being in contact with the mounting portion, and the distal ends of the second blade and the third blade extending in a direction away from the mounting portion. The mounting portion includes a first mounting portion and a second mounting portion, the second mounting portion being stacked on top of the first mounting portion along the rotational axis of the blade, the first blade being in contact with the first mounting portion, and the second blade and the third blade being in contact with the second mounting portion. The upwardly inclined blade, the downwardly inclined blade, the second blade, and the third blade are alternately arranged circumferentially along the mounting portion.

[0034] In this embodiment of the food preparation cup assembly, the ingredients are sequentially pulverized by the four types of blades, resulting in high pulverization efficiency. Furthermore, the second mounting part is stacked on top of the first mounting part, allowing the mixing and pulverizing blades to be designed as two independent components, reducing design difficulty and cost, and ensuring higher relative positional accuracy between the first and third blades.

[0035] In some embodiments, each of the upper inclined blade, the lower inclined blade, the second blade, and the third blade is arranged in pairs, and the two blades in each pair are arranged symmetrically with respect to the center of the mounting portion.

[0036] In this embodiment, the food processor assembly uses two upward-tilting blades, two downward-tilting blades, two second blades, and two third blades to pulverize the ingredients, resulting in higher pulverization efficiency.

[0037] In some embodiments, the cross-sectional profile of the cooking cavity is generally square, pentagonal, or hexagonal.

[0038] The cooking cup assembly in this embodiment avoids too many corners, which would make the cross-section of the cooking cavity nearly circular, resulting in better turbulence of the ingredients. On the other hand, it also reduces the manufacturing difficulty and cost of the cooking cup.

[0039] In some embodiments, the first blade has a first side and a second side, at least one of the first side and the second side is a cutting edge side, and the blade width between the first side and the second side first increases and then decreases in the direction away from the mounting portion.

[0040] In this embodiment, the cooking cup assembly is designed so that the width of the first blade increases first and then decreases along the direction away from the mounting part. This ensures that the change in the width of the first blade does not exhibit a single-trend correlation with the change in the rotation speed of the ingredients in the cooking chamber. This effectively interferes with the movement of the ingredients, allowing the first blade to exert a greater force on them. As a result, the ingredients are pulverized efficiently, with good pulverization effect, less foam, and lower noise.

[0041] In some embodiments, the first blade is provided with a pressure relief hole extending along the thickness direction of the first blade, and the width of the pressure relief hole first increases and then decreases in the direction away from the mounting portion.

[0042] In this embodiment of the blending cup assembly, during the rotation of the first blade, water can flow through the pressure relief hole to balance the pressure on both sides of the first blade, effectively reducing the probability of cavitation. The pressure relief hole can also cut and break down cavitation, preventing cavitation from accumulating and generating excessive noise. In addition, the width of the pressure relief hole matches the width of the first blade, thus the pressure relief hole can adaptively balance the pressure difference in any area along the length of the first blade, effectively reducing the noise generated when blending and pulverizing food.

[0043] The food processor of this utility model includes a food processor cup assembly as described in any of the above embodiments.

[0044] The food processor of this utility model embodiment, by adopting the food processing cup assembly of the above embodiment, has high food pulverization efficiency and good pulverization effect. Attached Figure Description

[0059] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0060] The cooking cup assembly 100 of this utility model is described below with reference to the accompanying drawings.

[0061] It is understood that the mixing and pulverizing blade 200 of this utility model embodiment is generally also referred to as a mixing blade or a pulverizing blade. In the description of this utility model embodiment, "ingredients" should be interpreted broadly, for example, it is generally also referred to as an ingredient mixture, a mixture of ingredients and water, a mixture, a fluid, a slurry, a liquid, etc. The mixing and pulverizing blade 200 of this utility model embodiment can be used in the food processor assembly 100, which can be, for example, a blender, a juicer, a soy milk maker, etc., and can be used to prepare soy milk, rice paste, corn juice, nut milk, mung bean soup, etc., but is not limited thereto.

[0062] The cooking cup assembly 100 of this utility model embodiment includes a cooking cup and a blending and pulverizing blade 200. The cooking cup has a cooking cavity 44. The cross-sectional outline of the cooking cavity 44 is generally a regular polygon. The sides of the regular polygon are straight segments or arc segments 42 that bulge outward from the center away from the center of the cooking cavity 44. Adjacent sides are directly connected or connected through transition segments. A baffle 45 is provided at the corner of the cooking cavity 44. The mixing and pulverizing blade 200 includes a mounting part 1 and blades. The blades include a first blade 2, the proximal end of which is connected to the mounting part 1, and the distal end of the first blade 2 extending away from the mounting part 1. The first blade 2 includes an upwardly inclined blade 21 and a downwardly inclined blade 22. The upwardly inclined blade 21 is inclined upward relative to the mounting part 1, and the downwardly inclined blade 22 is inclined downward relative to the mounting part 1. In a plane orthogonal to the rotation axis of the blades, the distance between the distal end of the downwardly inclined blade 22 and the baffle 45 is E, and the distance between the distal end of the upwardly inclined blade 21 and the baffle 45 is F, where 13.3mm≤E≤32.1mm, and / or 13.3mm≤F≤32.1mm.

[0063] It should be noted that the cooking cup includes a cup body 4 and a heating plate 5. The bottom of the cup body 4 has an inwardly extending annular flange 41, and the heating plate 5 is located at the bottom of the cooking cavity 44 and supported on the annular flange 41. E and F can both be 13.3mm, 26mm, or 32.1mm. "Generally regular polygon" means that it can be a strictly standard regular polygon, or it can be a non-standard regular polygon. For example, the edges of the cross-section of the cooking cavity 44 can be curved, with rounded transitions between adjacent edges.

[0064] The cooking cup assembly 100 of this utility model has a generally regular polygonal outline in the cross-section of the cooking cavity 44, which makes the distance between different positions of the inner wall of the cooking cavity 44 and the center of the cooking cavity 44 unequal. Furthermore, by setting baffles 45 at the corners of the cooking cavity 44, when the food is centrifugally moved along the inner wall of the cooking cavity 44 under the agitation of the mixing blade 200, it will be blocked by the baffles 45 when flowing from the center of the side wall of the cooking cavity 44 to the corner, and it will also be blocked by the cup wall when flowing from the corner of the cooking cavity 44 to the center of the side wall. This results in a large change in speed and flow direction, effectively turbulent the food, and making the food more efficient to be pulverized under the agitation of the mixing blade 200.

[0065] Furthermore, by using the first blade 2, which includes an upwardly inclined blade 21 and a downwardly inclined blade 22 that are respectively inclined upwards and downwards relative to the mounting part 1, and with 13.3mm≤E≤32.1mm and 13.3mm≤F≤32.1mm, the food can be three-dimensionally stirred. This not only avoids the first blade 2 having insufficient stirring force on the food near the baffle 45, thus preventing poor food flow and scorching, but also provides the food with a larger stirring space between the baffle 45 and the first blade 2. The food particles are more uniform and have a better taste when stirred by the first blade 2.

[0066] In some embodiments, 0.85 ≤ F / E ≤ 1.23. This allows the cutting radii of the upper inclined blade 21 and the lower inclined blade 22 to form a gradient, achieving multi-dimensional cutting of the food. The probability of turbulence during food movement is higher, the crushing efficiency is higher, the particle uniformity of the food under the agitation of the first blade 2 is higher, and the taste is better.

[0067] For example, F / E can be 0.85, 1, or 1.23.

[0068] In some embodiments, such as Figure 3 As shown, the blade also includes a second blade 8 and a third blade 9. The proximal ends of the second blade 8 and the third blade 9 are connected to the mounting portion 1. The distal ends of the second blade 8 and the third blade 9 extend in a direction away from the mounting portion 1. In a plane orthogonal to the rotation axis of the blade, the distance between the distal end of the second blade 8 and the baffle 45 is G, and the distance between the distal end of the third blade 9 and the baffle 45 is H, where 21mm≤G≤50.6mm, 24.5mm≤H≤55.6mm, and / or, 1.05≤G / E≤1.85, 1.28≤H / E≤1.97.

[0069] This design avoids insufficient agitation force from the mixing blades 200 on the food near the turbulence ribs 45, thus preventing poor food flow. It also provides greater agitation space between the turbulence ribs 45 and the mixing blades 200, resulting in more uniform particle size and better texture. Furthermore, it creates a gradient in the cutting radius of the mixing blades 200, enabling multi-dimensional cutting of the food. This increases the likelihood of turbulence during food movement and improves pulverization efficiency.

[0070] For example, the distance G between the distal end of the second blade 8 and the baffle 45 can be 21 mm, 35 mm, or 50.6 mm, and the distance H between the distal end of the third blade 9 and the baffle 45 can be 24.5 mm, 41 mm, or 55.6 mm. G / E can be 1.05, 1.4, or 1.85, and H / E can be 1.28, 1.5, or 1.97.

[0071] In some embodiments, such as Figure 3 As shown, in a plane orthogonal to the rotation axis of the blade, the distance between the distal end of the downward inclined blade 22 and the center of the side wall of the cooking cavity 44 is P1, and the distance between the distal end of the upward inclined blade 21 and the center of the side wall is P2, where 10.3mm≤P1≤28.1mm and 10.3mm≤P2≤28.1mm.

[0072] By setting P1≤28.1mm and P2≤28.1mm, the distance between the distal ends of the upward and downward tilting blades 21 and the center of the side wall of the blending cup is prevented from being too small. This avoids the food being squeezed between the downward tilting blade 22 and the cup wall, preventing it from flowing freely and reducing the chance of the food burning at the bottom. By setting P1≥10.3mm and P2≥10.3mm, food at corners is prevented from being unable to be stirred and thus burning at the bottom. At the same time, the above settings also provide more space for the food to be stirred, resulting in more uniform particle size and better texture when the food is stirred by the upward and downward tilting blades 21 and 22.

[0073] For example, the distance P1 between the distal end of the inclined blade and the center of the sidewall of the cooking cavity 44 can be 10.3 mm, 19 mm or 28.1 mm, and the distance P2 between the distal end of the upper inclined blade 21 and the center of the sidewall can be 10.3 mm, 19 mm or 28.1 mm.

[0074] In some embodiments, in a plane orthogonal to the rotation axis of the blade, the distance between the distal end of the downwardly inclined blade 22 and the center of the sidewall of the cooking cavity 44 is P1, and the distance between the distal end of the upwardly inclined blade 21 and the center of the sidewall of the cooking cavity 44 is P2, wherein 0.85≤P1 / P2≤1.23.

[0075] This allows the cutting radii of the upper inclined blade 21 and the lower inclined blade 22 to form a gradient, enabling multi-dimensional cutting of the food. The food is more likely to experience turbulence during movement, resulting in higher pulverization efficiency. The food particles under the agitation of the first blade 2 have higher uniformity and better taste.

[0076] In some embodiments, such as Figure 2 As shown, the distance between the distal end of the downward inclined blade 22 and the bottom wall of the cooking cavity 44 is Q1, and the distance between the distal end of the upward inclined blade 21 and the bottom wall of the cooking cavity 44 is Q2, wherein 3.5mm≤Q1≤8.6mm and 16.3mm≤Q2≤29.3mm.

[0077] This avoids food getting stuck due to an insufficient gap between the downward-sloping blade 22 and the bottom wall of the cooking cavity 44, thus reducing the likelihood of the motor failing to start due to excessive resistance caused by food getting stuck. On the other hand, it effectively prevents the distance between the downward-sloping blade 22 and the bottom wall of the cooking cavity 44 from being too large, which would prevent the food at the bottom from being stirred and lifted, leading to burning at the bottom.

[0078] For example, the distance Q1 between the distal end of the downward-tilted blade 22 and the bottom wall of the cooking cavity 44 can be 3.5mm, 6mm or 8.6mm, and the distance Q2 between the distal end of the upward-tilted blade 21 and the bottom wall of the cooking cavity 44 can be 16.3mm, 23mm or 29.3mm.

[0079] In some embodiments, the ratio of the length of the baffle 45 to the depth of the cooking cavity 44 is A, where 0.35 ≤ A ≤ 0.8. By setting A ≥ 0.35, the baffle 45 can turbulentize more areas of the food, effectively improving the food grinding efficiency. By setting A ≤ 0.8, excessive obstruction of the food by the baffle 45 can be avoided, preventing food from splashing and reducing the chance of food adhering to the lid and causing waste, while also reducing the cost of the cooking cup.

[0080] For example, the ratio A of the length of the baffle 45 to the depth of the cooking cavity 44 can be 0.35, 0.6 or 0.8.

[0081] In some embodiments, such as Figure 12 As shown, the lower end of the baffle 45 is flush with the bottom wall of the cooking cavity 44. Alternatively, the lower end of the baffle 45 is higher than the bottom wall of the cooking cavity 44. The minimum distance between the lower end of the baffle 45 and the bottom wall of the cooking cavity 44 is L1, where 5mm≤L1≤15.5.

[0082] By extending the lower end of the baffle 45 to the bottom wall of the cooking chamber 44, the ingredients at the bottom of the cooking chamber 44, undergoing centrifugal motion, are easily blocked by the baffle 45 when passing through corners, thus changing their flow velocity and direction, resulting in a better turbulence effect. Alternatively, by setting L1 ≥ 5mm, denser ingredients at the bottom of the cooking chamber 44 are effectively prevented from being stuck at corners due to the obstruction of the baffle 45. By setting L1 ≤ 15.5mm, the baffle 45 ensures a good turbulence effect on the ingredients at the bottom of the cooking chamber 44, thereby improving the food grinding efficiency.

[0083] For example, four baffles 45 are provided at the four corners, and the lower end of the baffles 45 abuts against the heating plate 5. Alternatively, the lower end of the baffles 45 is spaced apart from the bottom end of the cooking cavity 44, and the minimum distance L1 between the lower end of the baffles 45 and the bottom end of the cooking cavity 44 can be 5mm, 10mm or 15.5mm.

[0084] In some embodiments, the ratio of the sum of the cross-sectional areas of the plurality of baffles 45 to the minimum cross-sectional area of ​​the cooking cavity 44 is U, where 0.0029≤U≤0.0044. By setting 0.0029≤U≤0.0044, on the one hand, it is possible to achieve baffles on more areas of the food to effectively improve the food crushing efficiency; on the other hand, it can prevent the baffles 45 from obstructing the food too much, which would cause the food to splash and reduce the chance of it sticking to the lid and causing waste, while also reducing the cost of the cooking cup.

[0085] For example, the ratio U of the sum of the cross-sectional areas of the multiple baffles 45 to the minimum cross-sectional area of ​​the cooking cavity 44 can be 0.0029, 0.0035 or 0.0044.

[0086] In some embodiments, such as Figure 3 As shown, the size of the protrusion of the baffle 45 toward the center of the cooking cavity 44 is L2. The profile of the cross-section of the corner is an arc shape with a radius of curvature of R. In the plane orthogonal to the rotation axis of the blade, the maximum distance between the rotation axis of the blade and the cavity wall at the corner is L3, and the distance between the rotation axis and the center of the side wall of the cooking cavity 44 is L4. Wherein, 2.5mm≤L2≤8.5mm, and / or, 0.35≤L2 / L3≤0.8, 0.017≤R / L2≤0.033, 0.3≤(L3-L4) / L2≤0.75.

[0087] With the above settings, on the one hand, when the ingredients undergo centrifugal motion, they can be better blocked by the turbulence ribs 45 and part of the cup wall of the main body, giving the ingredients a better turbulence effect and thus achieving higher pulverization efficiency. On the other hand, it reduces the probability of ingredients getting stuck near the turbulence ribs 45, further ensuring the pulverization effect of the ingredients. The particles of the ingredients are more uniform and have a better texture when pulverized by the mixing blade 200.

[0088] For example, the dimension L2 of the baffle 45 protruding toward the center of the cooking cavity 44 can be 2.5mm, 5.5mm or 8.5mm, L2 / L3 can be 0.35, 0.6 or 0.8, R / L2 can be 0.017, 0.023 or 0.033, and (L3-L4) / L2 can be 0.3, 0.5 or 0.75.

[0089] In some embodiments, the blade further includes a second blade 8 and a third blade 9. The proximal ends of the second blade 8 and the third blade 9 are connected to the mounting portion 1, and the distal ends of the second blade 8 and the third blade 9 extend in a direction away from the mounting portion 1. The mounting portion 1 includes a first mounting portion 11 and a second mounting portion 12. The second mounting portion 12 is stacked on top of the first mounting portion 11 along the rotation axis of the blade. The first blade 2 is connected to the first mounting portion 11, and the second blade 8 and the third blade 9 are connected to the second mounting portion 12. The upper inclined blade 21, the lower inclined blade 22, the second blade 8, and the third blade 9 are alternately arranged circumferentially along the mounting portion 1. In this case, the food is pulverized by the above four types of blades in sequence, thereby achieving higher pulverization efficiency. Furthermore, the second mounting portion 12 is stacked on top of the first mounting portion 11, allowing the stirring and pulverizing blade 200 to be designed as two independent components, which reduces design difficulty and cost, and also improves the relative positional accuracy of the first blade 2 to the third blade 9.

[0090] Optionally, each of the upward-tilting blade 21, downward-tilting blade 22, second blade 8, and third blade 9 is arranged in pairs, with the two blades in each pair arranged symmetrically with respect to the center of the mounting part 1. In this case, the two upward-tilting blades 21, the two downward-tilting blades 22, the two second blades 8, and the two third blades 9 work together to pulverize the food, resulting in higher pulverization efficiency.

[0091] For example, such as Figures 4-10 As shown, there are pairs of second blades 8, third blades 9, upper inclined blades 21, and lower inclined blades 22, with two second blades 8, two third blades 9, two upper inclined blades 21, and two lower inclined blades 22 arranged alternately along the circumference of the mounting portion 1. Both the first mounting portion 11 and the second mounting portion 12 are provided with polygonal holes, allowing them to be detachably fitted into the cutter shaft 3 through these holes. This completes the stacking of the second mounting portion 12 on the first mounting portion 11 and ensures the relative fixation of the first mounting portion 11 and the second mounting portion 12 in the circumferential direction.

[0092] In some embodiments, the cross-sectional outline of the cooking cavity 44 is generally square, pentagonal, or hexagonal. This arrangement avoids too many corners, making the cross-section of the cooking cavity 44 closer to a circle, resulting in better turbulence of ingredients in the cooking cup. It also reduces the manufacturing difficulty and cost of the cooking cup.

[0093] For example, such as Figure 3 and Figure 11 As shown, the cross-sectional outline of the cooking cavity 44 is roughly square, and at this time, the cooking cavity 44 forms four corners that facilitate airflow.

[0094] In some embodiments, the first blade 2 has a first side 23 and a second side 24, at least one of the first side 23 and the second side 24 being a cutting edge side. The blade width between the first side 23 and the second side 24 first increases and then decreases in the direction away from the mounting portion 1. By setting the width of the first blade 2 to first increase and then decrease in the direction away from the mounting portion 1, the change in the width of the first blade 2 does not show a single-trend correlation with the change in the rotational speed of the food in the cooking cavity 44, so as to effectively interfere with the movement of the food, allowing the first blade 2 to exert a greater force on the food, thereby resulting in high food crushing efficiency, good crushing effect, less foam, and low noise.

[0095] It should be noted that, as Figure 8 As shown, the blade width between the first side 23 and the second side 24 refers to the arc length W between the first intersection point of the first side 23 and the first intersection point of the circle with the center of the mounting part 1 and the second intersection point of the circle with the second side 24.

[0096] In some embodiments, the first blade 2 is provided with a pressure relief hole 25 extending along the thickness direction of the first blade 2, and the width of the pressure relief hole 25 first increases and then decreases in the direction away from the mounting portion 1.

[0097] During the rotation of the first blade 2, water can flow through the pressure relief hole 25 to balance the pressure on both sides of the first blade 2, effectively reducing the probability of cavitation. The pressure relief hole 25 can also cut and break down cavitation, preventing cavitation from accumulating and generating excessive noise. In addition, the width of the pressure relief hole 25 matches the width of the first blade 2, thus the pressure relief hole 25 can adaptively balance the pressure difference in any area along the length of the first blade 2, effectively reducing the noise generated when grinding and pulverizing food.

[0098] For example, such as Figure 4 As shown, each first blade 2 is provided with a pressure relief hole 25. On a plane orthogonal to the rotation axis of the blade, the projected outer contour of the pressure relief hole 25 has the same shape as the projected outer contour of the first blade 2.
