Description

Technical Field

[0001] The utility model relates to the field of food processing machines, in particular to a food processing machine with optimized crushing effect. Background Art

[0002] In order to improve the crushing effect of the crushing blade on the ingredients, common food processing machines such as soymilk machines and wall breaking machines are generally equipped with spoiler ribs on the inner wall of the cup. The spoiler ribs can increase the turbulence of the fluid in the cup, which is beneficial to increase the contact probability between the ingredients and the crushing blade, thereby improving the crushing fineness and improving the taste of drinks such as slurry.

[0003] Existing improvements on spoiler ribs are often only improvements in their shape. For example, in the solution disclosed in patent CN115844237A, the spoiler surface is set as a curved surface that is concave toward the spoiler rib and / or the inner wall of the cup body to provide a guiding effect on the food, so as to guide the food fluid to the middle of the cup body, thereby promoting the contact between the food and the crushing blade, thereby improving the effect of food cutting. On the one hand, this solution does not take into account the relationship between the spoiler rib and the blade, resulting in a weak guiding effect of the spoiler surface on the food, which is not conducive to greatly increasing the probability of contact between the food and the blade. On the other hand, considering that the food is still affected by the fluid in the cup body after leaving the spoiler surface, only a small part of the food guided by the spoiler surface can flow toward the expected center of the cup body, making it difficult to fully crush the food, resulting in uneven particle size of the food crushed, and the crushing effect of the food still needs to be improved.

[0006] The food processing machine with optimized crushing effect of the utility model also has the following additional technical features:

The first arc, the second arc and the rotating circle enclose the target area, and the part of the frontal surface between the starting end and the vertex end is located in the target area.

[0008] The portion of the frontal surface between the starting end and the vertex end is an arc surface, and the arc surface, the first arc line and the second arc line are all concavely arranged toward the rotation direction of the blade. The radius of the circle where the arc surface is located is R, the radius of the circle where the first arc line is located is R1, and the radius of the circle where the second arc line is located is R2, wherein R2≤R≤R1.

[0009] Two tangent lines drawn from the starting end to the rotating circle formed along the outer end of the blade when the blade rotates form a first straight tangent line and a second straight tangent line respectively. The first straight tangent line, the second straight tangent line and the rotating circle enclose the target area, and the part of the frontal surface between the starting end and the vertex end is located in the target area.

[0010] The first straight tangent line and the second straight tangent line are symmetrically arranged about the line from the starting end to the center of the rotating circle, and the portion of the frontal surface between the starting end and the vertex end is a plane, and an angle formed between the plane and the line from the starting end to the center of the rotating circle is not greater than half of an angle formed by the first straight tangent line and the second straight tangent line.

[0011] The portion of the frontal surface between the starting end and the vertex end is arranged to coincide with a tangent of the two tangents or an extension of the tangent and the inner wall of the grinding cup forming a smaller angle.

[0015] The processing tool set comprises more than two blades of different lengths, and the rotating circle is formed along the outer end of the blade when the blade with the smallest length rotates.

[0016] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0017] 1. The food processing machine with optimized crushing effect of the utility model is designed to solve the problem in the prior art that the improvement of the spoiler ribs is not associated with the crushing knife, resulting in uneven crushing fineness and low crushing efficiency. The present application optimizes the arrangement of the oncoming surface of the spoiler ribs, associates the setting of the oncoming surface with the blade parameters, and limits the position of the oncoming surface between the starting end and the vertex end. When the material is in the target area formed by the two tangents and the rotating circle, the material can be blocked by the oncoming surface and then guided to the working area of ​​the blade, which increases the contact opportunity between the material and the blade, promotes the full crushing of the material, and improves the crushing fineness and crushing efficiency.

[0018] Among them, the part of the oncoming surface between the starting end and the vertex end plays a major role in guiding the material. When the oncoming surface also includes other parts, the other parts can also guide the material.

[0019] 2. As a preferred embodiment, two tangent lines drawn from the starting end to the rotating circle formed along the outer end of the blade when the blade rotates form a first arc and a second arc respectively, and the first arc, the second arc and the rotating circle enclose the target area, and the portion of the oncoming surface between the starting end and the vertex end is located within the target area. In this embodiment, the first arc and the second arc are both portions on a tangent circle tangent to the rotating circle. The position of the portion of the oncoming surface between the starting end and the vertex end is determined based on the first arc and the second arc, which can improve the position determination accuracy. When the oncoming surface is in this range, the number of times the material contacts the blade after diversion can be greatly increased, thereby optimizing the crushing fineness and crushing efficiency.

[0020] As a preferred embodiment of the present embodiment, the portion of the frontal surface between the starting end and the vertex end is an arc surface, and the arc surface, the first arc line and the second arc line are all set concavely toward the rotation direction of the blade, the radius of the circle where the arc surface is located is R, the radius of the circle where the first arc line is located is R1, and the radius of the circle where the second arc line is located is R2, wherein R2≤R≤R1. The use of a concave arc surface can increase the contact area between the material and the arc surface. Secondly, the arc surface is in the same bending direction as the first arc line and the second arc line. The position of the arc surface can be easily determined according to the range defined by R1 and R2, which reduces the difficulty of setting and facilitates the processing of the spoiler ribs.

[0021] 3. As a preferred embodiment, two tangent lines drawn from the starting end to the rotating circle formed along the outer end of the blade when the blade rotates form a first straight tangent line and a second straight tangent line respectively, and the first straight tangent line, the second straight tangent line and the rotating circle enclose the target area, and the portion of the oncoming surface between the starting end and the vertex end is located within the target area. In this embodiment, the target area enclosed by the first straight tangent line, the second straight tangent line and the rotating circle is relatively large, which is conducive to determining the position of the portion of the oncoming surface between the starting end and the vertex end, and ensuring the reliability of the oncoming surface in guiding the material.

[0022] As a preferred embodiment of the present embodiment, the first straight tangent line and the second straight tangent line are symmetrically arranged about the line connecting the starting end to the center of the rotating circle, the portion of the oncoming surface between the starting end and the vertex end is a plane, and the angle formed between the plane and the line connecting the starting end to the center of the rotating circle is not greater than half of the angle formed by the first straight tangent line and the second straight tangent line. The oncoming surface design of the plane has a simple structure and is easy to process. The position of the oncoming surface is determined according to the angle between the first straight tangent line and the second straight tangent line, which is easy to determine and easy to reduce errors.

[0023] 4. As a preferred embodiment, the portion of the oncoming surface between the starting end and the apex end is arranged to coincide with a tangent formed by a tangent or an extension of the two tangents and the inner wall of the crushing cup at a smaller angle. Since the material will be affected by the rotating fluid after leaving the oncoming surface, when the portion of the oncoming surface between the starting end and the apex end is arranged to coincide with a tangent formed by a tangent or an extension of the two tangents and the inner wall of the crushing cup at a smaller angle, the material guided by the oncoming surface can still be mostly aligned with the working area of ​​the tool after being pushed by the fluid, which can more offset the position deviation caused by the influence of the fluid thrust, so that more material is guided to the working area of ​​the tool, thereby improving the cutting efficiency; and at this position, the direction of the material tends to be perpendicular to the blade, and the cutting effect is better.

[0024] 5. As a preferred embodiment, the starting point is located at the root of the oncoming surface and is connected to the inner wall of the crushing cup. In this embodiment, the entire oncoming surface guides the material, and the oncoming surface is smooth and continuous as a whole, which can increase the contact area with the material, and is conducive to the continuous movement of the material to the working area of ​​the blade after being continuously guided, and orderly and efficient cutting can be performed, which can improve the crushing efficiency.

[0025] 6. As a preferred embodiment, the starting point is located between the vertex of the oncoming surface and the root of the oncoming surface, and the distance from the starting point to the vertex in the radial direction of the crushing cup is not less than half of the distance from the vertex to the root in the radial direction of the crushing cup. In this embodiment, the oncoming surface includes two parts. Since the part of the oncoming surface between the starting point and the vertex is more effective in guiding the material, the size of this part of the oncoming surface is kept in a suitable proportion, which can ensure that more material is guided to the working area of ​​the tool, so that the material is fully crushed and the uneven crushing of the material is avoided.

[0026] As a preferred embodiment of the present embodiment, the portion of the oncoming surface between the starting end and the root is a plane or an arc surface, and forms a discontinuous plane or a discontinuous arc surface with the portion of the oncoming surface between the starting end and the vertex end. This embodiment expands the shape of the oncoming surface, and both parts of the oncoming surface can guide the material. By reasonably setting the angle of the oncoming surface between the starting end and the root, it is helpful to assist in the guidance. For example, after the material contacts this part of the oncoming surface, it can rebound at a small angle and continue to contact the other part of the oncoming surface. The first part of the oncoming surface plays a role of transition guidance, which is conducive to guiding the material close to the cup wall, so that the material is fully guided to the working area of ​​the blade to achieve full crushing.

[0027] 7. As a preferred embodiment, the processing knife set includes more than two blades of different lengths, and the rotating circle is formed along the outer end of the blade when the blade with the smallest length rotates. When a plurality of blades of different lengths are used, it is convenient to cut materials in different radial directions, which can achieve full crushing and improve crushing efficiency; the blade with the smallest length is arranged closer to the center of the crushing cup, and the blade with a larger length at the periphery is convenient for pre-cutting large-volume materials. By making the pre-cut materials contact more with the small blades, it is beneficial to improve the crushing fineness, so that the final material has a delicate and smooth taste.

[0044] like Figures 1 to 5 As shown, the present application provides a food processor for optimizing the crushing effect, including a crushing cup 10, a processing knife group arranged on the crushing cup 10 and a motor for driving the processing knife group to work, the inner wall surface of the crushing cup 10 is provided with an inwardly protruding spoiler rib 11, the spoiler rib 11 includes a front face 12, the front face 12 is provided with a starting end 121, the front face 12 is close to the center of the crushing cup 10 as a vertex end 122, the processing knife group includes a blade 14, two tangents are drawn from the starting end 121 to the rotating circle 15 formed along the outer end of the blade 14 when the blade 14 rotates, the two tangents and the rotating circle 15 enclose a target area, the part of the front face 12 between the starting end 121 and the vertex end 122 is located in the target area to guide the material to the working area of ​​the blade 14.

[0045] The utility model discloses a food processing machine with optimized crushing effect. In order to solve the problem in the prior art that the improvement of the spoiler rib 11 lacks association with the crushing knife, resulting in uneven crushing fineness and low crushing efficiency, the present application optimizes the arrangement of the oncoming surface 12 of the spoiler rib 11, and associates the setting of the oncoming surface 12 with the parameters of the blade 14. By limiting the position of the part of the oncoming surface 12 between the starting end 121 and the vertex end 122, when the material is in the target area enclosed by the two tangents and the rotating circle 15, the material can be blocked by the oncoming surface 12 and then guided to the working area of ​​the blade 14, thereby increasing the contact opportunity between the material and the blade 14, promoting full crushing of the material, and improving the crushing fineness and crushing efficiency.

[0046] like Figure 1 and Figure 2 As shown, the spoiler rib 11 protrudes from the inner wall of the pulverizing cup 10, and is preferably integrally formed with the pulverizing cup 10. The cross section of the spoiler rib 11 is approximately triangular, and the spoiler rib 11 mainly includes two opposite spoiler surfaces: a frontal surface 12 and a rear surface 13, as shown in FIG. Figure 2 As shown, the upstream surface 12 faces the direction of rotation of the cutter, and the downstream surface 13 faces the direction of rotation of the cutter. During the food processing, the spoiler ribs 11 have a spoiler effect on the fluid in the crushing cup 10. At the same time, when the material is thrown to the spoiler ribs 11 as the cutter rotates, the material collides with the upstream surface 12 and is guided by the upstream surface 12, thereby promoting the material to be pushed to the center area of ​​the crushing cup 10 again to contact the blade 14, so that the material is cut cyclically, and finally a beverage with a certain crushing particle size is produced. The present application mainly improves the setting position of at least part of the upstream surface 12, and can be applied to different forms of the upstream surface 12. The setting area is defined according to the relationship between the upstream surface 12 and the blade 14, so that the upstream surface 12 in the area can better play a guiding role on the material, so that more material is constantly in contact with the blade 14, thereby improving the crushing effect.

[0047] As a preferred embodiment of the present application, two tangent lines drawn from the rotating circle 15 formed along the outer end of the blade 14 when rotating from the starting end 121 to the blade 14 respectively form a first arc 16 and a second arc 17. The first arc 16, the second arc 17 and the rotating circle 15 enclose the target area, and the portion of the frontal surface 12 between the starting end 121 and the vertex end 122 is located within the target area.

[0048] like Figure 3 or Figure 4As shown, the first arc 16 and the second arc 17 are both parts of a tangent circle tangent to the rotating circle 15. The position of the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122 is determined based on the first arc 16 and the second arc 17, which can improve the accuracy of position determination. When the oncoming surface 12 is in this range, the number of contacts between the material and the blade 14 after diversion can be greatly increased, thereby optimizing the crushing fineness and crushing efficiency.

[0049] The portion of the frontal surface 12 between the starting end 121 and the vertex end 122 can be either an arc surface or a plane surface.

[0050] In one embodiment, the portion of the frontal surface 12 between the starting end 121 and the vertex end 122 is an arc surface, and the arc surface, the first arc line 16 and the second arc line 17 are all concavely arranged toward the rotation direction of the blade 14, the radius of the circle where the arc surface is located is R, the radius of the circle where the first arc line 16 is located is R1, and the radius of the circle where the second arc line 17 is located is R2, wherein R2≤R≤R1.

[0051] like Figure 3 or Figure 4 As shown, by limiting R according to R1 and R2, the curvature of the arc surface can be determined, so that the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122 is located within the target area enclosed by the first arc 16, the second arc 17 and the rotating circle 15, so that when the material is guided by this portion of the oncoming surface 12, it can move toward the working area of ​​the blade 14, which is beneficial to the sufficient fine crushing of the material.

[0052] Preferably, the arc surface of the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122 is arranged to overlap with the second arc 17 (the smaller arc of the two arcs), so that after the material leaves the oncoming surface 12, even if the material is pushed by the fluid, the range of the material flowing between the first arc 16 and the second arc 17 is the largest, which can ensure that more material contacts the blade 14, thereby greatly improving the crushing efficiency and crushing fineness. Specifically, after the material leaves the oncoming surface 12, the material flows in the tangential direction of the second arc 17, which can more offset the position deviation caused by the water flow, thereby helping to reduce the degree of deviation between the material and the working area of ​​the tool.

[0053] As a preferred embodiment of the present application, two tangents drawn from the starting end 121 to the rotating circle 15 formed along the outer end of the blade 14 when the blade 14 rotates form a first straight tangent 18 and a second straight tangent 19 respectively. The first straight tangent 18, the second straight tangent 19 and the rotating circle 15 enclose the target area, and the portion of the frontal surface 12 between the starting end 121 and the vertex end 122 is located within the target area.

[0054] like Figure 5 As shown, the target area enclosed by the first straight tangent line 18, the second straight tangent line 19 and the rotating circle 15 is relatively large, which is conducive to determining the position of the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122, thereby ensuring the reliability of the oncoming surface 12 in guiding the material.

[0055] The portion of the frontal surface 12 between the starting end 121 and the vertex end 122 can be either an arc surface or a plane surface.

[0056] In one embodiment, the first straight tangent line 18 and the second straight tangent line 19 are symmetrically arranged about the line from the starting end 121 to the center of the rotating circle 15, and the portion of the frontal surface 12 between the starting end 121 and the vertex end 122 is a plane, and an angle formed between the plane and the line from the starting end 121 to the center of the rotating circle 15 is not greater than half of the angle formed by the first straight tangent line 18 and the second straight tangent line 19.

[0057] like Figure 5 As shown, if the first straight tangent 18 and the second straight tangent 19 form an angle of 2θ, then the angle formed by the plane where the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122 is located and the line connecting the starting end 121 to the center of the rotating circle 15 is ≤θ. The oncoming surface 12 is determined based on the angle θ, and the method is simple and has a small error.

[0058] Preferably, the plane where the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122 is located coincides with the second straight tangent 19, so that after the material leaves the oncoming surface 12, even if the material is pushed by the fluid, the range of the material flowing between the first straight tangent 18 and the second straight tangent 19 is the largest, which can ensure that more material contacts the blade 14, thereby greatly improving the crushing efficiency and crushing fineness. It should be noted that after the material leaves the oncoming surface 12, the material flows toward the tool working area along the extension direction of the planar oncoming surface 12. At this time, under the influence of the water flow, the deviation caused to the material increases the degree of deviation of the material from the tool working area. The flow rate of the material can be increased by increasing the rotation power of the tool to reduce the influence of the water flow thrust.

[0059] As a preferred embodiment of the present application, the portion of the frontal surface 12 between the starting end 121 and the vertex end 122 is arranged to coincide with a tangent of the two tangents or an extension of the tangent that forms a smaller angle with the inner wall of the grinding cup 10 .

[0060] Since the material will be affected by the rotating fluid after leaving the frontal surface 12, when the frontal surface 12 is between the starting end 121 and the vertex end 122, and the tangent of the two tangents or the extension of the tangent forms a tangent with a smaller angle with the inner wall of the grinding cup 10, the material guided by the frontal surface 12 can still be mostly aligned with the working area of ​​the tool after being pushed by the fluid, which can more offset the position deviation caused by the influence of the fluid thrust, so that more material is guided to the working area of ​​the tool, thereby improving the cutting efficiency; and in this position, the direction of the material tends to be perpendicular to the blade, and the cutting effect is better.

[0061] Specifically, in Figure 3 or Figure 4 In the example of , the arc surface of the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122 is arranged to coincide with the second arc line 17. Figure 5 In the example, the plane where the portion of the frontal surface 12 between the starting end 121 and the vertex end 122 is located coincides with the second straight tangent line 19 .

[0062] by Figure 3 For example, the angle formed by the second arc 17 (or the tangent of the second arc 17) and the inner wall of the pulverizing cup 10 is α1, and the angle formed by the first arc 16 (or the tangent of the first arc 16) and the inner wall of the pulverizing cup 10 is α2, α1<α2, and α1 is used as the limit value of the angle between the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122 and the inner wall of the pulverizing cup 10. If the angle between the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122 and the inner wall of the pulverizing cup 10 is smaller than the above limit value, although more materials can be directed to the working area of ​​the tool, the tool workload becomes larger at this time, which may exceed the tolerance range and cause safety hazards. In addition, if the angle between the portion of the frontal surface 12 between the starting end 121 and the vertex end 122 and the inner wall of the grinding cup 10 is further reduced compared to the above-mentioned limit value, the frontal surface 12 will cause excessive obstruction to the material, and the material will easily form a local vortex in the space between the frontal surface 12 and the inner wall of the grinding cup 10, which will be detrimental to the flow of the material toward the working area of ​​the tool.

[0063] As a preferred embodiment of the present application, the starting end 121 is located at the root 123 of the frontal surface 12 and is connected to the inner wall of the grinding cup 10 .

[0064] like Figure 3 or Figure 5 As shown, the entire surface of the frontal surface 12 guides the material. The frontal surface 12 is smooth and continuous as a whole, which can increase the contact area with the material, and is conducive to the material being continuously guided and continuously moving to the working area of ​​the blade 14, so as to perform orderly and efficient cutting, thereby improving the crushing efficiency.

[0065] As a preferred embodiment of the present application, the starting end 121 is located between the vertex end 122 of the oncoming surface 12 and the root 123 of the oncoming surface 12, and the distance from the starting end 121 to the vertex end 122 in the radial direction of the crushing cup 10 is not less than half of the distance from the vertex end 122 to the root 123 in the radial direction of the crushing cup 10.

[0066] like Figure 4 As shown, the oncoming surface 12 includes two parts. Since the part of the oncoming surface 12 between the starting end 121 and the vertex end 122 is more effective in guiding the material, the size of this part of the oncoming surface 12 is kept in an appropriate proportion, which can ensure that more material is guided to the working area of ​​the tool, achieve sufficient crushing of the material, and avoid the situation where the material is crushed unevenly.

[0067] Furthermore, the portion of the oncoming surface 12 between the starting end 121 and the root 123 is a plane or an arc surface, and forms a discontinuous plane or a discontinuous arc surface with the portion of the oncoming surface 12 between the starting end 121 and the vertex end 122 .

[0068] This embodiment expands the shape of the oncoming surface 12, and the two parts of the oncoming surface 12 can guide the material. By reasonably setting the angle of the oncoming surface 12 between the starting end 121 and the root 123, it is helpful to assist in the guidance. For example, after the material contacts this part of the oncoming surface 12, it can rebound at a small angle and continue to contact the other part of the oncoming surface 12. The former part of the oncoming surface 12 plays a role of transition guidance, which is beneficial to guide the material close to the cup wall, so that the material is fully guided to the working area of ​​the blade 14 to achieve sufficient crushing.

[0069] In one embodiment, the processing knife set includes only one blade 14, and the rotating circle 15 is formed along the outer end of the blade 14 when the blade 14 rotates; in another embodiment, the processing knife set includes two or more blades 14 of different lengths, and the rotating circle 15 is formed along the outer end of one of the blades 14 when the blade 14 rotates. Figure 4 and Figure 6 As shown, when the processing tool set includes two blades 14 of different lengths, the rotating circle 15 can be formed along the outer end of the blade 14 when the smaller blade 14 rotates, and can also be formed along the outer end of the blade 14 when the larger blade 14 rotates.

[0070] As a preferred embodiment of the present application, the processing tool set includes more than two blades 14 of different lengths, and the rotating circle 15 is formed along the outer end of the blade 14 when the blade 14 with the smallest length rotates.

[0071] When using blades 14 of various lengths, it is convenient to cut materials in different radial directions, which can achieve sufficient crushing and improve crushing efficiency; the blade 14 with the smallest length is arranged closer to the center of the crushing cup 10, and the blade 14 with a larger length on the periphery is convenient for pre-cutting large-volume materials. By making the pre-cut materials contact more with the small blades 14, it is beneficial to improve the crushing fineness, so that the final material has a delicate and smooth taste.

[0072] like Figures 2 to 5 As shown, the processing knife group includes a two-leaf blade 14 with a shorter length and a four-leaf blade 14 with a longer length. The longer blade 14 is beneficial for cutting large-volume materials in the initial stage. Then, the materials can be more in contact with the small blade 14 in the center under the guidance of the frontal surface 12. Through multiple cutting, the effect of fine crushing can be achieved, and uniform and efficient crushing can be realized.

[0073] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present utility model. Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
