Description

Technical Field

[0001] The present invention belongs to the technical field of food processors, and particularly relates to an energy-saving and efficient food processor. Background Art

[0002] In the field of food processors, traditional food processors usually only have ribs on the inner side of the cup body. When the cutter group rotates and stirs, these ribs can only play a role in radial turbulence. This makes the stirring effect poor during the process of stirring food materials, especially in the lower region of the cup assembly where the food materials are most concentrated. To achieve an ideal crushing effect, a relatively long stirring time is often required, resulting in high energy consumption. Summary of the Invention

[0003] (I) Object of the Invention

[0004] In order to overcome the above deficiencies, the object of the present invention is to provide an energy-saving and efficient food processor to solve the technical problems of poor stirring effect and high energy consumption of existing food processors.

[0005] (II) Technical Solution

[0006] To achieve the above object, the technical solution provided by the present application is as follows:

[0007] An energy-saving and efficient food processor, comprising: a housing, a driving device disposed in the housing, a cup holder disposed above the housing and connected to the housing, a cutter disc disposed in the cup holder and connected to the cup holder, a turbulence surface formed on the upper end surface of the cutter disc with continuous high and low undulations and inclined towards the center to form a vortex structure, a cutter body rotatably disposed at the center of the cutter disc, a cutter shaft including a lower end passing through the cup holder and the cutter disc and drivingly connected to the driving device, and a plurality of cutter groups layered on the upper end of the cutter shaft. The cutter group located above includes a plurality of first-type cutter blades bent upward and extending, and the cutter group located below includes a plurality of second-type cutter blades bent downward and extending, and a plurality of third-type cutter blades bent downward and extending and then bent horizontally again at the end and extending along the horizontal direction. The food processor further includes: a cup body covering the cup holder and detachably connected to the cup holder, and a plurality of turbulence ribs circumferentially spaced on the inner side wall of the cup body and extending along the height direction of the cup body;

[0008] By setting the above-mentioned structure, when the cutter group starts to rotate, the food processor of the present application drives the food fluid to rotate radially. At the same time, the raised part on the cutter disc disturbs the fluid, prompting the fluid to generate axial movement, just like "lifting" the food from the bottom of the container, pulling the food at the bottom upward, and performing axial turbulent flow on the food. In addition, with the help of the vortex structure at the bottom, a fluid vortex can be formed during the whipping process. Under this action, the food will move closer to the middle (the position of the cutter group), thereby increasing the contact probability between the food and the cutter group, making the whipping effect more delicate. Since the food can repeatedly contact the cutter group, the crushing efficiency is greatly improved, shortening the whipping time and reducing the energy consumption. In addition, the present application adopts a design in which the layered cutter group cooperates with the vortex-shaped turbulent flow surface of the cutter disc. The first type of blade on the upper layer is bent upward, which can further roll up and cut the food at the bottom, effectively preventing the food from accumulating at the lower part of the cup body. The second type of blade on the lower layer is bent downward, which can exert pressure on the food at the bottom, and the third type of blade throws the food towards the cup wall through the "Z-shaped" horizontal extension section (the second extension section). When the food is thrown to the cup wall, it will fall back under the longitudinal guidance of the turbulent flow ribs on the cup body, and then reflow to the center of the cutter disc under the action of the cutter disc vortex and be cut by the cutter group, forming a circulating crushing path. Due to the layered and differentiated design of various types of blades, the vertical and horizontal cutting directions are fully covered, further optimizing the whipping effect.

[0009] In some embodiments, the turbulent flow surface includes a plurality of turbulator units arranged at circumferential intervals and transition units connecting adjacent two turbulator units. Among them, each turbulator unit gradually bends and protrudes from the center of the turbulent flow surface towards the edge to form a slope structure, and the slope on one side of the slope structure is greater than the slope on the other side;

[0010] The steep slope side (with a larger slope) forms a "step-lifting" effect during the rotation of the cutter disc, and the food can move quickly upward along the steep slope, breaking through the traditional radial flow restriction; while the gentle slope side (with a smaller slope) guides the food to circulate downward through a gentle falling path, forming a reciprocating movement in the vertical direction. The curved connection of the transition unit avoids the flow dead zone between adjacent turbulator units, ensuring that the food maintains continuous axial movement during the lifting and falling processes.

[0011] In some embodiments, the cutter group located below further includes: a plurality of first type blades.

[0012] By adding the first type of blade to the lower cutter group, the upwardly bent blade and the downwardly bent second and third type blades form a complement, enhancing the vertical stirring force in the bottom area of the cup body, reducing food residue, and further improving the processing efficiency.

[0013] In some embodiments, the third type of blade includes, in sequential distribution: a first bent portion bent downward, a first extension section connected to the first bent portion and extending downward, a second bent portion connected to the first extension section and bent in the horizontal direction, and a second extension section extending in the horizontal direction;

[0014] The three-stage bending design also enables the third type of blade to have both vertical cutting and horizontal shearing functions at the same time. The first extension section cuts into the food ingredients at an inclined angle to reduce the initial impact force. The second extension section extends horizontally to extend the cutting path. The dual effects improve the crushing efficiency. In addition, the second extension also increases the disturbance effect on the lower-layer food ingredients. At the same time, the multi-stage bending disperses stress and reduces the risk of blade fracture.

[0015] In some embodiments, one side of each type of blade is a cutting edge and the other side is a blade back. The bending positions on the side of the blade back of the first, second, and third type of blades bulge outward to form a strengthened flow disturbance portion;

[0016] The protruding strengthened flow disturbance portion enhances the bending resistance strength of the blade root through geometric strengthening to avoid deformation under high loads. At the same time, this structure can further increase the flow disturbance effect, enhance the fluidity of the food ingredients during the stirring and cutting process, and improve the crushing effect.

[0017] In some embodiments, one side of each type of blade is a cutting edge and the other side is a blade back. The cutting edges of the first, second, and third type of blades form an inclined surface structure;

[0018] Setting the cutting edge into an outwardly convex inclined surface structure lengthens the cutting edge length, expands the crushing area, which is particularly beneficial for the tearing and decomposition of fibrous food ingredients. In addition, it can make the cutting trajectory expand in a spiral manner, promote the rotation of the food ingredients during the stirring process, and improve the crushing efficiency.

[0019] In some embodiments, the cutting edge inclined surface of the first type of blade is arranged downward, and the cutting edge inclined surfaces of the second type of blade and the third type of blade are arranged upward;

[0020] The differential design of the inclined surface directions of the upper and lower blades forms a two-way hydrodynamic effect, enabling the food ingredients to achieve three-dimensional tumbling in the cavity, and the crushing uniformity is increased by more than 40%.

[0021] In some embodiments, the contours of the first, second, and third type of blades gradually narrow from near the knife axis to away from the knife axis to form a sharp corner structure;

[0022] The sharp corner structure reduces the moment of inertia at the end of the blade through a progressive narrowing design, reducing energy consumption; at the same time, it enhances the cutting linear velocity at the end of the blade. The sharp corner design increases the linear velocity at the end of the blade by 15%-20%, forming a local high-pressure impact area, quickly breaking hard food ingredients such as nuts and ice cubes. At the same time, the turbulence generated by the sharp corner wake can prevent thick food ingredients from sticking to the knife surface. Description of the Drawings

[0040] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0041] The energy-saving and efficient food processor provided by the present invention has a core structure including components such as a machine housing 11, a driving device 14, a cup seat 8, a knife disc 10, a knife body and a cup body 13. A driving device 14 is installed inside the machine housing 11 to drive the rotation of the knife body as a power source. The cup seat 8 is fixedly connected above the machine housing 11, and a stable connection between the cup seat 8 and the machine housing 11 is achieved through a snap or bolt structure. A knife disc 10 is installed inside the cup seat 8, and the upper end surface of the knife disc 10 is designed as a vortex-shaped flow disturbance surface, which is formed by alternating arrangement of a plurality of arc-shaped protrusions and depressions and inclined towards the center direction. A rotatable knife body is provided at the center position of the knife disc 10. The knife body is connected to the driving device 14 through a knife shaft 4 passing through the cup seat 8 and the knife disc 10. The lower end of the knife shaft 4 is rotatably arranged on the knife disc 10 through a ball bearing 9, and the upper end is provided with two sets of knife groups arranged in layers to cut food materials in different areas respectively.

[0042] Specifically, the upper-layer knife group consists of a plurality of first-type blades 1 bent upward. When the knife body rotates, these blades can roll up the food materials at the bottom of the cup body 13 upward and crush them preliminarily to avoid the accumulation of food materials in the bottom area. The lower-layer knife group includes two types of blades: the second-type blades 2 are bent downward to apply pressure to the bottom food materials to enhance the cutting effect; the third-type blades 3 adopt a "Z-shaped" three-segment bending design, first extending downward and then horizontally bending, and their horizontal extension sections can throw the food materials towards the inner wall of the cup body 13. All the blades adopt a single-sided blade edge 5 design, with one side of the blade edge 5 being a sharp inclined surface and the other side being a smooth knife back 6 to ensure efficient cutting and minimum resistance.

[0043] Specifically, the cup body 13 covers the cup base 8 and is detachably connected through a snap or thread structure, facilitating cleaning. A plurality of longitudinal turbulence ribs 12 extending in the height direction are provided on the inner wall of the cup body 13. These turbulence ribs 12 can not only radially disturb the food ingredients thrown towards the inner wall of the cup body 13 by the third type of blade 3, but also play a role in guiding the flow, enabling the food ingredients to circulate up and down in the vertical direction and avoiding layering phenomena.

[0044] Furthermore, the vortex-shaped turbulence surface of the cutter head 10 is composed of turbulence units 101 and transition units 102 arranged at intervals in the circumferential direction. Each turbulence unit 101 gradually bends and protrudes from the center to the edge, forming an asymmetric slope structure - one side has a steep slope and the other side is gentle. The steep slope side generates a "step-up" effect when the cutter head 10 rotates, and the food ingredients move rapidly upward along the steep slope under the action of centrifugal force, breaking through the traditional radial flow limitation; the gentle slope side guides the food ingredients to fall downward through the gentle curved surface, forming a reciprocating cycle in the vertical direction. The curved surface connection of the transition unit 102 ensures the continuous flow of the food ingredients between adjacent turbulence units 101 and avoids dead zones.

[0045] Through the above structure, the vortex-shaped turbulence surface of the cutter head 10 and the layered cutter group cooperate to form a three-dimensional flow field in the food ingredient processing cavity. The upper blades roll up the food ingredients upward, the lower blades press downward and combine with horizontal shearing, and cooperate with the axial guidance of the turbulence surface, enabling the food ingredients to repeatedly contact the blades and be quickly crushed. Experiments show that this design improves the crushing efficiency of hard food ingredients (such as nuts) by 35% - 40%, while reducing the energy consumption by 15% - 20%. In addition, the modular design of the cup body 13 and the cutter group simplifies the cleaning process and improves the user experience.

[0046] Preferably, multiple first type blades 1 can also be provided in the lower cutter group and cooperate with the first type blades 1 in the upper cutter group to further stir the upper food ingredients.

[0047] Specifically, two first type blades 1 are formed in the upper cutter group, and four blades are formed in the lower cutter group. Two opposite blades are two first type blades 1, and one of the other two opposite blades is a second type blade 2 and the other is a third type blade 3.

[0048] Specifically, the third type of blade 3 includes: a first bent portion 301 bent downward, a first extended section 302 extending downward, a second bent portion 303 bent in the horizontal direction, and a second extended section 304 extending in the horizontal direction, which are connected to each other in the radial direction and distributed in sequence. One side of the first and second extended sections 304 is the blade edge 5 and the other side is the blade back 6.

[0049] Specifically, by the difference in the bending directions of the upper and lower layers of blade leaves, multi-dimensional cutting paths are formed, the contact area of the food materials is enlarged, and the crushing efficiency is improved. During the stirring and cutting process, the second extension section 304 of the third type of blade 3 in the lower layer can also push the food materials to spread towards the edge of the whipping cavity, improving the disturbance effect. The upward bending of the upper blade can drive the food materials to flow upward and then guide the food materials to fall back, forming a circulating whipping to avoid local accumulation. The combination of the first, second, and third types of blades 1, 2, and 3 can cover different crushing scenarios (such as the impact of hard food materials and the mixing of fluid food materials), achieving an improvement in versatility.

[0050] Preferably, the bending positions of the first, second, and third types of blades 1, 2, and 3 on one side of the blade back 6 bulge outwards to form a strengthened turbulence part 7. The protruding structure not only serves as a reinforcing rib to improve the bending strength of the blade (the load capacity is increased by more than 30%), but also serves as a turbulence plate to break the one-way movement of the food materials.

[0051] Preferably, the cutting edges 5 of the first, second, and third types of blades 1, 2, and 3 form an inclined plane structure, and the inclined cutting edges 5 form a wedge-shaped cutting angle, reducing the initial cutting resistance, lengthening the length of the cutting edges 5, expanding the crushing area, and being particularly beneficial to the tearing and decomposition of fibrous food materials (such as celery). In addition, the arc-shaped contour of the outwardly convex cutting edges 5 generates a centripetal force, pushing the food materials to gather towards the middle of the blade, improving the repeated crushing rate.

[0052] Preferably, in this application, the first type of blade 1 is downward, and the second and third types of blades 3 are upward. In this way, the upper blade cuts downward and the lower blade cuts upward, forming a counteracting crushing force, shortening the particle size of the food materials to the millimeter level. In addition, the difference in directions forces the food materials to move reciprocally in the vertical direction, and the crushing time is reduced by about 40% (compared with traditional one-way blades).

[0053] In this application, the included angle between the first extension section 302 and the horizontal line is optimized to be 15° - 75°, and the included angle of the third extension section is optimized to be 15° - 90°; the included angle between the second type of blade 2 and the horizontal line is optimized to be bent downward by 45° - 75°.

[0054] Preferably, in the present application, the height of the second extension section 304 is limited such that the interval between the highest point of the spoiler unit 101 is 3-30 mm. When the interval is 3-10 mm, the end of the knife blade closely cooperates with the steep side of the spoiler surface, increasing the crushing efficiency of hard food ingredients (such as nuts) by 20%-30%; when the interval is expanded to 10-20 mm, a moderate space is formed, reducing the entanglement of fibrous food ingredients and the accumulation of viscous food ingredients, and the residue amount is reduced by 15%-25%; when the interval is further increased to 20-30 mm, the centrifugal throwing force is enhanced, the turbulence effect is significant, while the air flow resistance is reduced, and the motor load fluctuation is reduced by 8%-12%. In addition, the gradient spacing design adapts to diverse processing scenarios: small spacing focuses on the rapid crushing of high-hardness food ingredients, medium spacing balances the versatility of fibrous and fluid food ingredients, and large spacing provides an extended cutting space for large food ingredients (such as frozen fruits), improving the overall efficiency.

[0055] It should be understood that the above specific embodiments of the present invention are only for illustrative explanation or interpretation of the principles of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
