Stirring knife assembly and food processor

Abstract

The utility model discloses a stirring knife assembly and a food processor. The stirring cutter assembly comprises a cutter shaft, a first blade and a second blade, wherein the first blade and the second blade are assembled on the cutter shaft. The first blades and the second blades are staggered in the circumferential direction of the cutter shaft and are spaced in the axial direction of the cutter shaft; the first blade and the second blade are both inclined upwards relative to the horizontal plane from the cutter shaft. Due to the fact that the first blades and the second blades are staggered in the circumferential direction and spaced in the axial direction of the cutter shaft, and the first blades and the second blades are inclined upwards relative to the horizontal plane from the cutter shaft, height difference exists between the cutter point and the cutter root part, the projection height of the first blades and the second blades in the axial direction of the cutter shaft is large, and therefore the cutter shaft is more stable. The covering height of the stirring knife assembly in the stirring process is large, and food material chopping is facilitated.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of small household appliances, in particular to a stirring blade assembly and a food processor. BACKGROUND

[0002] The food processor comprises a food material container, a stirring blade assembly and a driving device. The food material container comprises a food material containing cavity surrounded by a container bottom wall and a container side wall. The container bottom wall is located in a horizontal direction. The stirring blade assembly comprises a blade shaft rotationally assembled with the container bottom wall and a blade assembled on the blade shaft. The blade is a planar chopping blade. The driving device drives the stirring blade assembly to drive the blade to rotate in the food material containing cavity.

[0003] In the above food processor, since the blade is a planar chopping blade, the trajectory of the blade rotating is a circle parallel to the horizontal plane, so that the height covered by the stirring blade assembly in the axial direction of the blade shaft during the beating process is small, which is not conducive to chopping food materials. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to disclose a stirring blade assembly and a food processor. The stirring blade assembly covers a large height during the beating process, which can better chop food materials.

[0005] In a first aspect, the present application discloses a stirring blade assembly. The stirring blade assembly comprises a blade shaft and a first blade and a second blade assembled on the blade shaft. The first blade and the second blade are staggered in the circumferential direction of the blade shaft and are spaced apart in the axial direction of the blade shaft; the first blade and the second blade are both inclined upward relative to the horizontal plane from the blade shaft.

[0006] As described above, since the first blade and the second blade are staggered in the circumferential direction of the blade shaft and are spaced apart in the axial direction, and the first blade and the second blade are both inclined upward relative to the horizontal plane from the blade shaft, there is a height difference between the blade tip and the blade root, so that the projection height of the first blade and the second blade in the axial direction of the blade shaft is large, therefore, the height covered by the stirring blade assembly during the beating process is large, which is conducive to chopping food materials.

[0007] In some embodiments, the projection of the first blade and the projection of the second blade are symmetrical relative to the center of the blade shaft in the radial plane of the blade shaft.

[0008] As described above, since the projection of the first blade and the projection of the second blade are symmetrical relative to the center of the blade shaft in the radial plane of the blade shaft, it is conducive to force balance of the stirring blade assembly during rotation, and thus the food materials can be better chopped and chopped uniformly.

[0009] In some embodiments, the first blade and the second blade are inclined upward in an arc shape, a broken line shape or a straight line shape.

[0010] As arranged above, since the first blade and the second blade are inclined upward in an arc shape, a straight line shape or a broken line shape, it is easier to form a height difference between the blade tip and the blade root, and the food material in the height difference range can be chopped, thereby facilitating the chopping of the food material.

[0011] In some embodiments, in the case where the first blade and the second blade are in an arc shape, the first blade and the second blade are twisted along the length direction, respectively.

[0012] As arranged above, since the first blade and the second blade are twisted along the length direction, respectively, during the rotation of the first blade and the second blade, the food material moves along the surface twisted by the first blade and the second blade, and is turned over, and finally, the food material is mixed and chopped uniformly.

[0013] In some embodiments, in the case where the first blade and the second blade are in an arc shape or a broken line shape, the minimum inclination angle of the first blade and the second blade relative to the horizontal plane is a, and 5 degrees≤a≤30 degrees.

[0014] As arranged above, since the minimum inclination angle of the first blade and the second blade relative to the horizontal plane is a, and 5 degrees≤a≤30 degrees, on the one hand, it ensures that the first blade and the second blade have sufficient height in the axial direction of the blade shaft, and can chop the food material in a larger height range, and on the other hand, during use, the space between the first blade and the second blade and the inner wall of the food material container is relatively small, which is conducive to the chopping of the food material by the first blade and the second blade, such as to finally make the food material chopped uniformly.

[0015] In some embodiments, the first blade and the second blade are both in a plate shape, and are bent into at least two segments to form the broken line shape; the included angle formed by adjacent segments is b, and 120 degrees≤b≤160 degrees.

[0016] As arranged above, since the first blade and the second blade are in a broken line shape, and 120 degrees≤b≤160 degrees, the first blade and the second blade can also cover a larger height in the axial direction of the blade shaft, and finally, it is more conducive to the chopping of the food material.

[0017] In some embodiments, in the axial direction of the blade shaft, the projection height of the first blade and the projection height of the second blade partially overlap.

[0018] As set forth above, due to the partially overlapped projection height of the first blade and the second blade, it can be understood that the food material can be whipped twice at the same position, combined with the rotation of the stirring blade assembly, the food material at other positions is also brought to the overlapping part, so that the food material is fully whipped and chopped more uniformly.

[0019] In some embodiments, the first blade and the second blade each comprise a blade root connected with the blade shaft. The stirring blade assembly comprises an upper blade, the blade root of the upper blade is higher than the blade roots of the first blade and the second blade, and the upper blade is spaced apart from the first blade and the second blade in the axial direction of the blade shaft and staggered in the circumferential direction of the blade shaft.

[0020] As set forth above, due to the stirring blade assembly comprising the upper blade (such as the third blade) spaced apart from the first blade and the second blade in the axial direction of the blade shaft and staggered in the circumferential direction, the height covered by the rotation of the stirring blade assembly is larger, and the food material can be chopped more uniformly.

[0021] In some embodiments, the upper blade is inclined upward or downward relative to the horizontal plane in an arc shape, a broken line shape or a straight line shape; or, the upper blade is parallel to the horizontal plane.

[0022] As set forth above, the upper blade is inclined upward or downward relative to the horizontal plane in an arc shape, a broken line shape or a straight line shape, which is more conducive to increasing the height of the stirring blade assembly in the axial direction of the blade shaft, and more conducive to chopping the food material uniformly.

[0023] In some embodiments, the upper blade comprises a third blade and a fourth blade; in the radial plane of the blade shaft, the projection of the third blade and the projection of the fourth blade are symmetrical relative to the center of the blade shaft.

[0024] As set forth above, due to the upper blade comprising the third blade and the fourth blade, and the aforementioned stirring blade assembly comprising the first blade and the second blade, four blades are arranged in the axial direction of the blade shaft, the height of the cutting is larger, and more food material can be chopped and chopped uniformly. In addition, the projection of the third blade and the projection of the fourth blade are symmetrical relative to the center of the blade shaft, which is conducive to the force balance of the stirring blade assembly during rotation, and thus the food material can be chopped better.

[0025] In some embodiments, the blade root of the first blade is lower than the blade root of the second blade; the upper blade comprises a third blade; in the axial direction of the blade shaft, the projection height of the second blade and the projection height of the third blade are partially overlapped.

[0026] As set forth above, due to the partially overlapped projection height of the second blade and the third blade, it can be understood that the food material can be whipped twice at the same position, in combination with the rotation of the stirring blade assembly, the food material at other positions is also brought to the overlapped portion, thus, the food material is fully whipped and chopped more uniformly.

[0027] In a second aspect, the present application discloses a food processor. The food processor comprises a food material container, a driving device and any one of the aforementioned stirring blade assemblies. In the case that the stirring blade assembly only comprises the first blade and the second blade, the driving device drives the first blade and the second blade of the stirring blade assembly to rotate in the food material container. In the case that the stirring blade assembly comprises the first blade, the second blade and the upper blade, the driving device drives the first blade, the second blade and the upper blade of the stirring blade assembly to rotate in the food material container.

[0028] As set forth above, the food processor has at least the beneficial effects of the stirring blade assembly, which will not be repeated here. BRIEF DESCRIPTION OF DRAWINGS

[0046] The technical solutions in the embodiments (or, the “embodiments”) of the present application will be described clearly and completely with reference to the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0047] If the embodiments of the present application involve directional indications or positional relationships (for example, up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such directional indications or positional relationships are only used to explain the relative positional relationships, movement conditions, etc. between the components in a certain posture (as shown in the drawings); if the certain posture changes, the directional indications or positional relationships also change accordingly. In addition, the terms “first”, “second”, etc. in the embodiments of the present application are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0048] Referring to Figures 9 to 16 and in combination with Figure 1 and Figure 2The application discloses a stirring blade assembly 2. The stirring blade assembly 2 comprises a blade shaft 21 and a first blade 221 and a second blade 222 assembled on the blade shaft 21. In the embodiment shown in the application, the number of blades is four in total, which are a lower blade 22 and an upper blade 23. The lower blade 22 comprises the first blade 221 and the second blade 222. The upper blade 23 comprises a third blade 231 and a fourth blade 232. In other embodiments, the stirring blade assembly 2 can also not comprise the upper blade 23. The first blade 221 and the second blade 222 are circumferentially staggered on the blade shaft 21 and are spaced in the axial direction of the blade shaft 21. The first blade 221 and the second blade 222 are both inclined upward relative to the horizontal plane from the blade shaft 21.

[0049] As arranged above, due to the fact that the first blade 221 and the second blade 222 are circumferentially staggered on the blade shaft 21 and are spaced in the axial direction of the blade shaft 21, and the first blade 221 and the second blade 222 are both inclined upward relative to the horizontal plane from the blade shaft 21, there is a height difference between the blade tip and the blade root 211, so that the projection height of the first blade 221 and the second blade 222 in the axial direction of the blade shaft 21 is large, and therefore, the stirring blade assembly 2 covers a large height during stirring, which is beneficial to chopping food materials.

[0050] Referring to Figure 8 In the radial plane of the blade shaft 21, the projection of the first blade 221 and the projection of the second blade 222 are symmetric to the center of the blade shaft 21.

[0051] As arranged above, due to the fact that in the radial plane of the blade shaft 21, the projection of the first blade 221 and the projection of the second blade 222 are symmetric to the center of the blade shaft 21, it is beneficial to balance the force of the stirring blade assembly 2 during rotation, and therefore, the food materials can be better chopped.

[0052] Referring to Figures 9 to 13 The first blade 221 and the second blade 222 are both inclined upward relative to the horizontal plane from the blade shaft 21 and are curved in an arc shape. Figures 14 to 16 The first blade 221 and the second blade 222 are both inclined upward relative to the horizontal plane from the blade shaft 21 and are bent into two sections to realize the fold line type. Figures 14 to 16It can be understood that the blade in a flat plate shape is bent into two sections. The two sections are marked as a first bent section 2211 and a second bent section 2212. The first blade 221 and the second blade 222 can also be non-flat plate-shaped blades bent into two sections. The number of bent sections is not limited to two sections as shown in the figure, and can be three sections, four sections, and the like. In some embodiments, the second blade 222 can also not be upwardly inclined to be arc-shaped, linear, or bent into multiple sections relative to the horizontal plane, only the first blade 221 is inclined upward relative to the horizontal plane. In some embodiments, the first blade 221 and the second blade 222 can also be linearly inclined upward.

[0053] As described above, due to the first blade 221 and the second blade 222 being upwardly inclined to be arc-shaped, linear, or bent, it is easier to form a height difference between the blade tip and the blade root 211, and the food material in the height difference range can also be chopped, which is beneficial to chopping the food material.

[0054] Referring to Figures 9 to 13 In the case where the first blade 221 and the second blade 222 are arc-shaped, the first blade 221 and the second blade 222 are twisted along the length direction, respectively. Figure 9 The twisting direction is indicated by an arrow R.

[0055] As described above, due to the first blade 221 and the second blade 222 being twisted along the length direction, respectively, during the rotation of the first blade 221 and the second blade 222, the food material will move along the surface of the first blade 221 and the second blade 222 twisted, and be turned over, and finally the food material is mixed and chopped uniformly.

[0056] Referring to Figure 9 , Figure 10 and Figure 15 In the case where the first blade 221 and the second blade 222 are upwardly inclined to be arc-shaped relative to the horizontal plane, the minimum inclination angle of the first blade 221 and the second blade 222 relative to the horizontal plane is a, and 5 degrees ≤ a ≤ 30 degrees. For example, 5 degrees, 7 degrees, 9 degrees, 10 degrees, 12 degrees, 13 degrees, 15 degrees, 17 degrees, 19 degrees, 20 degrees, 23 degrees, 25 degrees, 28 degrees, or 30 degrees. Referring to Figure 15 In the case where the first blade 221 and the second blade 222 are upwardly inclined to be linear relative to the horizontal plane, there is also 5 degrees ≤ a ≤ 30 degrees.

[0057] As set forth above, since 5 degrees≤a≤30 degrees, on the one hand, the first blade and the second blade have sufficient height in the axial direction of the blade shaft, and can shred food materials in a large height range, on the other hand, the space between the first blade and the second blade and the inner wall of the food container is relatively small during use, which is conducive to the first blade and the second blade shredding food materials, such as, ultimately making the food materials shredded uniformly.

[0058] Referring to Figure 15 , the first blade 221 and the second blade 222 are both plate-shaped, and are bent into at least two segments to form the zigzag shape; the included angle between adjacent segments is b, and 120 degrees≤b≤160 degrees, such as 120 degrees, 125 degrees, 128 degrees, 130 degrees, 133 degrees, 135 degrees, 138 degrees, 140 degrees, 143 degrees, 145 degrees, 149 degrees, 150 degrees, 151 degrees, 153 degrees, 155 degrees, 158 degrees or 160 degrees.

[0059] As set forth above, since the first blade 221 and the second blade 222 are zigzag-shaped, and 120 degrees≤b≤160 degrees, the first blade 221 and the second blade 222 can also cover a large height in the axial direction of the blade shaft 21, ultimately, more conducive to shredding food materials.

[0060] Referring to Figure 10 , Figure 12 and Figure 15 , in the axial direction of the blade shaft 21, the projection height of the first blade 221 and the projection height of the second blade 222 partially overlap. The overlapping height is M in the figure.

[0061] As set forth above, since the projection height of the first blade 221 and the projection height of the second blade 222 partially overlap, it can be understood that the food materials can be whipped twice at the same position, combined with the rotation of the stirring blade assembly 2, other food materials are also brought to the overlapping part, so that the food materials are fully whipped and shredded more uniformly.

[0062] Referring to Figures 8 to 16 and combining Figure 1 and Figure 2 , the first blade 221 and the second blade 222 both include a blade root portion 211 connected with the blade shaft 21. The stirring blade assembly 2 includes an upper blade 23, the blade root portion 211 of the upper blade 23 is higher than the blade root portion 211 of the first blade 221 and the blade root portion 211 of the second blade 222, and the upper blade 23 is spaced apart from the first blade 221 and the second blade 222 in the axial direction of the blade shaft 21 and is staggered in the circumferential direction of the blade shaft 21. Figures 8 to 16The upper blade 23 includes a third blade 231 and a fourth blade 232, as shown in FIG. 3. However, the number of the upper blade 23 is not limited to two, and can be one, three, or the like.

[0063] As shown in the above arrangement, the stirring blade assembly 2 further includes the upper blade 23 (e.g., the third blade 231) spaced apart from the first blade 221 and the second blade 222 in the axial direction of the blade shaft 21 and circumferentially offset from the first blade 221 and the second blade 222. Thus, the stirring blade assembly 2 has a greater height of coverage, and can more effectively and uniformly shred the food materials.

[0064] Referring to Figure 12 and Figure 13 , the upper blade 23 is upwardly inclined to be arc-shaped relative to the horizontal plane, referring to Figure 10 and Figure 11 , the upper blade 23 is downwardly inclined to be arc-shaped relative to the horizontal plane. As a variation of the above embodiment, in combination with the inspiration obtained from the shapes of the first blade 221 and the second blade 222 in Figures 14 to 16 , the upper blade 23 can also be upwardly inclined to be linear relative to the horizontal plane, or downwardly inclined to be linear, the upper blade 23 can be upwardly inclined to be broken-line relative to the horizontal plane, or the upper blade 23 can be downwardly inclined to be broken-line relative to the horizontal plane. Referring to Figure 9 and in combination with Figure 1 , the upper blade 23 is parallel to the horizontal plane.

[0065] As shown in the above arrangement, the upper blade 23 is upwardly or downwardly inclined to be arc-shaped, broken-line, or linear relative to the horizontal plane, which is more conducive to increasing the height of the stirring blade assembly in the axial direction of the blade shaft 21, and more conducive to shredding the food materials and shredding them uniformly.

[0066] Referring to Figure 8 and in combination with Figures 10 to 16 , the upper blade 23 includes a third blade 231 and a fourth blade 232; in the radial plane of the blade shaft 21, the projection of the third blade 231 and the projection of the fourth blade 232 are symmetrically relative to the center of the blade shaft 21.

[0067] As shown in the above arrangement, the upper blade 23 includes a third blade 231 and a fourth blade 232, and the aforementioned stirring blade assembly includes a first blade 221 and a second blade 222. Four blades are arranged spaced apart in the axial direction of the blade shaft 21, which has a greater height of cutting and can shred more food materials and shred them uniformly. In addition, the projection of the third blade 231 and the projection of the fourth blade 232 are symmetrically relative to the center of the blade shaft 21, which is conducive to force balance of the stirring blade assembly 2 during rotation, and thus, can better shred the food materials.

[0068] In some embodiments, the first blade 221 is lower than the second blade 222 in the axial direction of the shaft 21. The upper blade 23 comprises a third blade 231. The projection height of the second blade 222 and the projection height of the third blade 231 partially overlap in the axial direction of the shaft 21. Figure 11 and Figure 13 The height of the overlapping part is m. It can be understood by the skilled in the art that the projection height of the fourth blade 232 and the projection height of the third blade 231 can or can not overlap in the radial plane of the shaft 21.

[0069] As described above, since the projection height of the second blade 222 and the projection height of the third blade 231 partially overlap, it can be understood that the food material can be whipped twice at the same position. In combination with the rotation of the stirring blade assembly 2, the food material at other positions is also brought to the overlapping part. Thus, the food material is sufficiently whipped and chopped more uniformly.

[0070] Referring to Figure 1 and Figure 2 In a second aspect, the present application discloses a food processor. The food processor comprises a food material container 1, a driving device 3 and any one of the stirring blade assemblies 2 described above. In the case where the stirring blade assembly 2 only comprises the lower blade 22 (the first blade 221 and the second blade 222), the driving device 3 drives the first blade 221 and the second blade 222 of the stirring blade assembly 2 to rotate in the food material container 1. In the case where the stirring blade assembly 2 comprises the lower blade 22 and the upper blade 23, the driving device 3 drives the first blade 221, the second blade 222 and the upper blade 23 of the stirring blade assembly 2 to rotate in the food material container 1. Figure 1 The food processor illustrated is a meat grinder. It can be understood by the skilled in the art that the food processor is not limited to a meat grinder, but can also be a vegetable grinder and the like.

[0071] Referring to Figure 1 and in combination with Figure 2 , Figure 6 and Figure 7 The food material container 1 comprises a bottom cavity 11 for containing food material. The bottom cavity 11 comprises a shaft mounting portion 110 and a cavity wall 111 surrounding the shaft mounting portion 110. The cavity wall 111 is inclined with respect to the horizontal plane and is a rotation surface formed by rotating one turn around the rotation center line of the stirring blade assembly. The rotation center of the stirring blade assembly 2 can be understood as the shaft 21 of the stirring blade assembly 2. The bottom cavity 11 decreases in the vertical direction. Referring to Figure 1 and Figure 6 The decrease can be gradual. Referring to Figure 7The cavity wall 111 of the bottom cavity 11 comprises a first cavity wall formed by rotating a first straight line 1111 and a second cavity wall formed by rotating a second straight line 1112. The first straight line 1111 and the second straight line 1112 are bent relative to each other. The first cavity wall 111 encloses a first through-conducting circular truncated cone, and the second cavity wall encloses a second through-conducting circular truncated cone. The decreasing can be gradual in the first circular truncated cone part and gradual in the second circular truncated cone part, but as a whole, the first circular truncated cone to the second circular truncated cone is not gradually decreasing. In addition, the decreasing can not be gradual, and the function described later can be achieved. The shape of the rotating surface is not limited, and the bottom cavity 11 can be reduced to achieve the function described later.

[0072] The blade shaft 21 of the stirring blade assembly 2 is rotationally assembled with the center of the blade shaft mounting portion 110. Figure 5 It is shown that the center of the blade shaft mounting portion 110 is provided with a through hole 1102 for mounting a rotating shaft 1101; Figure 6 and Figure 7 It is shown that the rotating shaft 1101 is mounted in the through hole 1102. The blade shaft 21 is sleeved with the rotating shaft 1101 to realize the rotational assembly of the blade shaft 21 and the center of the blade shaft mounting portion 110. Of course, the rotational assembly is not limited to this, as long as the stirring blade assembly 2 can rotate.

[0073] As described above, since the cavity wall 111 is inclined relative to the horizontal plane and is a rotating surface, the bottom cavity 11 decreases along the vertical direction towards the blade shaft mounting portion 110. There is no corner 190 formed by the container bottom wall 191 and the container side wall 192 as shown in Figure 17 The food materials will not accumulate at the corner 190 to cause some food materials to be unable to be chopped, and finally, the food materials will not accumulate and will be gathered towards the blade shaft mounting portion 110 due to the gravity of the food materials themselves. At the same time, the food materials are moved by the high-speed rotation of the lower blade 22 of the stirring blade assembly 2 to generate centrifugal force, so that the food materials in the bottom cavity 11 generate stable circulation to ensure sufficient chopping, and the chopping of the food materials is more uniform.

[0074] Therefore, based on the function of the cavity wall 111 of the bottom cavity 11, in some embodiments, the food material container 1 used with the stirring blade assembly 2 of the present application can also not be the structure as shown in Figure 1 、 Figure 6 and Figure 7

[0075] Referring to Figure 1 ​The first blade 221 and the second blade 222 each include a blade tip. A gap 1110 is formed between the first blade 221 and the cavity wall 111 and between the second blade 222 and the cavity wall 111, respectively. In the direction from the blade root 211 to the blade tip, the width of the gap 1110 is equal everywhere, that is, the width of the gap 1110 between the first blade 221 and the cavity wall 111 is equal everywhere, and the width of the gap 1110 between the second blade 222 and the cavity wall 111 is equal everywhere. As a variation of the above embodiment, in the direction from the blade root 211 to the blade tip, the width of the gap 1110 gradually increases, and the difference between the minimum width and the maximum width is A, 0mm < A ≤ 5mm, or gradually decreases, and the difference between the minimum width and the maximum width is A, 0mm < A ≤ 5mm, such as 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.3mm, 2.5mm, 2.8mm, 3mm, 3.3mm, 3.5mm, 3.8mm, 4mm, 4.3mm, 4.5mm, 4.8mm or 5mm. Figure 1 In some embodiments, the gap between the blade tip and the cavity wall 111 is the minimum width d1, and the gap between the blade root 211 and the cavity wall 111 is the maximum width D1, in which case A = D1-d1; in other embodiments, the gap between the blade tip and the cavity wall 111 is the maximum width D1, and the gap between the blade root 211 and the cavity wall 111 is the minimum width d1, in which case A = D1-d1. By the same reasoning, the maximum width and the minimum width of the gap between the second blade 222 and the cavity wall 111 also have the above two cases, but A = D2-d2.

[0076] As set out above, because the width of the gap is equal everywhere in the direction from the blade root 211 to the blade tip, or the difference between the maximum width and the minimum width is within the above range, compared with the way in which the width of the gap gradually increases in the direction from the blade root 211 to the blade tip, the food material is confined in a smaller space, and the first blade 221 or the second blade 222 is subjected to uniform force, making it easier to chop the food material. In the embodiment in which the width of the gap gradually increases, there can be no food material near the blade tip, and it is easier to cause the food material to concentrate near the blade root 211, making it difficult for the first blade 221 or the second blade 222 to chop the food material, for example, the stirring knife assembly 2 can not be able to rotate because there is too much food material.

[0077] Referring to Figure 2 and Figure 5 The food material container 1 includes a plurality of turbulence ribs 13. Figure 2 and Figure 5Four turbulence ribs 13 are shown. However, the number of turbulence ribs 13 is not limited to this, for example, the number of turbulence ribs 13 is 2-8. The turbulence ribs 13 are distributed at intervals in the circumferential direction of the food container 1, each of the turbulence ribs 13 extends along the depth direction of the upper cavity 12 on the side wall of the upper cavity 12, and also extends on the cavity wall 111 of the bottom cavity 11 towards the knife shaft 21.

[0078] Referring to Figure 7 , the turbulence ribs 13 are only provided on the side wall 121 of the upper cavity 12, the turbulence ribs are arranged at intervals in the circumferential direction of the upper cavity, and each of the turbulence ribs 13 extends along the depth direction of the upper cavity 12.

[0079] As described above, by providing the turbulence ribs 13, the turbulence effect of the turbulence ribs 13 combines the food material gathering along the cavity wall 111 towards the knife shaft mounting portion 110, and the food material is more evenly chopped. Of course, in the case where the turbulence ribs 13 also extend on the cavity wall 111 of the bottom cavity 11 towards the knife shaft 21, more food material is disturbed, and the food material is more evenly chopped.

[0080] Referring to Figures 2 to 4 , the food processor further comprises a plurality of support feet 4, each of the support feet 4 comprises a first support portion 41 and a second support portion 42. The second support portions 42 intersect, and the intersection point is located directly below the knife shaft 21. The intersection is not limited to the cross intersection as shown in the figure, it can be three, and all the support feet 4 enclose a support space. The food container 1 is located in the support space and in contact with the first support portion 41 and the second support portion 42.

[0081] As described above, by providing a plurality of support feet 4, and the food container 1 is located in the support space and in contact with the first support portion 41 and the second support portion 42, and in addition, the second support portions 42 intersect, so that the contact part of the support feet 4 and the food container 1 is more, and the support is stable.

[0082] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structure described in the above embodiments and shown in the accompanying drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
