Description
Technical Field
[0001] The present application relates to the technical field of small household appliances, and in particular to a cutter head assembly and a food processor. Background Art
[0002] A food processor includes a blade assembly. The blade assembly comprises a disc body and a blade assembly. The disc body includes a disc cavity defined by a bottom wall and side walls. The blade assembly is rotatably assembled with the disc bottom wall. During operation of the food processor, the blade assembly is driven to stir food within the disc cavity. However, it has been discovered that the blade assembly may not fully stir food at the bottom edge of the disc cavity, resulting in uneven mixing. Utility Model Content
[0003] The purpose of this application is to disclose a cutter disc assembly and a food processor. The cutter disc assembly can mix food evenly.
[0004] In a first aspect, the present application discloses a cutter disc assembly. The cutter disc assembly includes a disc body and a cutter assembly. The cutter assembly includes a cutter shaft. The disc body includes a bottom wall and side walls, the bottom wall being rotatably assembled with the cutter shaft. The side walls and the bottom wall define a disc cavity, which includes a bottom surface and side surfaces. The side surfaces include an arc-shaped surface connected to the bottom surface and formed by rotating an arc around the rotation centerline of the cutter shaft. The center of the arc is offset from the rotation centerline of the cutter shaft.
[0005] As described above, since the center of the circle corresponding to the arc deviates from the rotation centerline of the blade shaft, compared with the case where the center of the circle corresponding to the arc is located on the rotation centerline, the side of the disc cavity is more inclined toward the outside of the blade shaft. Thus, on the one hand, the center of the circle of the side of the disc cavity deviates from the rotation centerline, and when whipping, the food accumulated on the side of the disc cavity generates certain small vortices on the side. These small vortices are different from the large vortices generated around the rotation centerline. The small vortices circulate in the up and down directions, which helps to mix the food more evenly. On the other hand, in the process of the blade whipping to form turbulence, the water flow is better and the exchange is faster, and more water enters the bottom edge area of the disc cavity. Ultimately, the food in the bottom edge area of the disc cavity can be fully stirred, and the food is mixed more evenly. In the case where a heating element is provided on the side wall of the disc body, because the food at the bottom edge of the disc cavity can also be fully stirred, the food in the bottom edge area of the disc cavity is not ignored and can be effectively heated, so the overall heating efficiency is high.
[0006] In some embodiments, the arc is a brachistochrone curve.
[0007] As described above, since the arc is the brachistochrone curve, combining the brachistochrone curve with the center of the arc offset from the blade axis's rotational center allows food to fall more quickly along the sides of the disc cavity, resulting in greater impact energy from the blades on the food and better mixing of the food and water, resulting in a more even mixing of the food. If a heating element is provided on the sidewalls of the disc, the characteristics of the brachistochrone curve allow the blades to drive the food-water mixture within the disc cavity against the sides with greater impact force, preventing food from sticking to the sides and, in turn, preventing the sides from being burned.
[0008] In some embodiments, the knife assembly includes multiple blades assembled on the knife shaft, and on the radial plane of the knife shaft, the center of the circle is located in the circle formed by the rotation of the blades; in the axial direction of the knife shaft, the multiple blades include the highest knife tip and the lowest knife tip, and the center of the circle is located between the highest knife tip and the lowest knife tip.
[0009] With the above arrangement, the center of the circle lies within the circle formed by the rotation of the blades on the radial plane of the blade shaft; and the center of the circle lies between the highest and lowest blade tips on the axial direction of the blade shaft. This arrangement further ensures that the aforementioned small eddies are distinct from the large eddies generated around the centerline of rotation, improves water flow and exchange, and allows more water to enter the bottom edge of the dish cavity, ultimately resulting in more even mixing of food. In the presence of a heating element, this prevents food from sticking to the sides of the dish cavity, further helping to prevent the sides from being burned.
[0010] In some embodiments, the distance that the center of the circle deviates from the rotation center line is M, and along the axial direction of the knife shaft, the distance between the center of the circle and the bottom surface of the disc cavity is H, 0<M / H≤1 / 2; the radius of the cavity opening of the disc cavity is N, 1 / 3≤M / N≤1 / 2.
[0011] As set above, 0<M / H≤1 / 2 and 1 / 3≤M / N≤1 / 2, the turbulence effect generated by the blade can be better, and the food can be mixed more evenly in the end.
[0012] In some embodiments, the blade shaft is assembled to the bottom wall of the disk body through a bearing seat, so that the bearing seat and the bottom wall of the disk body form an intersection, the arc is connected to the intersection, and the central angle corresponding to the arc is β, 0 degrees < β ≤ 90 degrees; or, the edge of the bottom wall of the disk body is located outside the intersection, the arc is connected to the edge of the bottom surface of the disk body cavity, and the central angle corresponding to the arc is β, 30 degrees ≤ β ≤ 90 degrees.
[0013] As set above, 0 degrees ≤ β ≤ 90 degrees, or 30 degrees ≤ β ≤ 90 degrees. This condition combined with the center of the circle corresponding to the aforementioned arc deviating from the rotation center line of the knife axis can achieve a good turbulence effect and more uniform mixing of food.
[0014] In some embodiments, the disk side wall includes a side wall top relative to the disk bottom wall, and the cutter disc assembly includes a heating element, which is located at the side wall top and arranged around the circumference of the disk side wall.
[0015] In the above arrangement, because the heating element is located at the top of the side wall and is arranged circumferentially around the side wall of the dish body, the heating element is far away from the bottom wall of the dish body. The heat generated by the heating element is transferred to the bottom wall of the dish body through the side wall of the dish body. The bottom surface of the dish body cavity is the inner surface of the dish body bottom wall. In this way, the bottom wall of the dish body is heated evenly, and the bottom surface of the dish body cavity is less likely to be burned. In addition, the turbulence generated by the rotation of the blade can drive the food within the dish body cavity, which also makes the side and bottom surfaces of the dish body cavity less likely to be burned.
[0016] In some embodiments, the knife assembly includes multiple blades assembled with the knife shaft, and along the axial direction of the knife shaft, the multiple blades include a lowest knife tip, the distance between the top of the heating element and the bottom surface of the disk cavity is L2, and the distance between the lowest knife tip and the bottom surface of the disk cavity is L1, 0.25≤L1 / L2≤0.75.
[0017] As set above, since 0.25≤L1 / L2≤0.75, the heating area on the side surface of the disc cavity of the side wall of the disc body corresponding to the heating element is heated by the heating element, and this area is close to the turbulence area of the blade, and the turbulence of the blade (at least the turbulence generated by the blade with the lowest blade tip) acts more effectively on the heating area. The stirring effect of the blade is good, which makes the fluidity of the food better. On the one hand, the food is mixed more evenly. On the other hand, the food can be separated from the side surface of the disc cavity to prevent the side surface of the disc cavity from being stained by food and being burned. Correspondingly, it can prevent the bottom surface of the disc cavity from being stained by food and being burned.
[0018] In some embodiments, the side surface of the disc cavity includes a bottom edge connected to the bottom surface of the disc cavity and a top edge relative to the bottom edge; the angle between the tangent plane passing through the top edge and the bottom edge and the bottom surface of the disc cavity is α, 90 degrees ≤ α ≤ 170 degrees.
[0019] As set up above, when the angle is 90 degrees ≤ α ≤ 170 degrees, the turbulence generated by the blades makes the stirring effect good and the fluidity of the food good. On the one hand, the food can be mixed evenly. On the other hand, when the side wall of the dish body is provided with a heating element, the side surface and the bottom surface of the dish body cavity are prevented from being stained with food and being burned.
[0020] In some embodiments, the knife assembly includes a plurality of blades assembled with the knife shaft, and at least part of the plurality of blades is located in the disc body cavity; along the radial direction of the knife shaft, the distance between the lowest tip of the plurality of blades and the side surface of the disc body cavity is P1; the width of the projection of the side surface of the disc body cavity on the radial plane of the knife shaft is P2, 0.1≤P1 / P2≤0.6.
[0021] As set up above, since 0.1≤P1 / P2≤0.6, the distance between the side of the disc cavity and the blade will not be too far, so that the turbulence of the blade (at least the turbulence generated by the blade with the lowest blade tip) can more effectively act on the area between the side of the disc cavity and the blade with the lowest blade tip, which has a good stirring effect on the food and makes the food fluidity good. Thus, on the one hand, the food is mixed more evenly, and on the other hand, when a heating element is provided on the side wall of the disc body, the food is prevented from sticking to the side of the disc cavity and getting burnt. In the case where a heating element is provided, the heating element is arranged circumferentially around the side wall of the disc body, first heating the side wall of the disc body, and the heat is transferred to the bottom wall of the disc body through the side wall of the disc body. The bottom wall of the disc body is evenly heated, and combined with the turbulence generated by the blade, the fluidity of the food is good, and the bottom surface of the disc cavity will not stick to the food and get burnt. In summary, the above setting can avoid the problem of food with poor fluidity accumulating at the bottom of the disc and getting burnt, thereby improving the user experience.
[0022] In some embodiments, the knife assembly includes a plurality of blades assembled with the knife shaft, and among the blade tips of the plurality of blades, along the axial direction of the knife shaft, the lowest blade tip is located inside the disc cavity, and the highest blade tip is located outside the disc cavity; the knife disc assembly includes a heating element, and the heating element is arranged around the circumference of the disc side wall, and the heating element contacts the disc side wall to form a contact surface; along the axial direction of the knife shaft, the lowest blade tip is located between the top edge and the bottom edge of the contact surface.
[0023] As set up as above, since the highest blade tip is located outside the disc cavity and the lowest blade tip is located inside the disc cavity and between the top edge and the bottom edge of the contact surface, the heating area on the side of the disc cavity corresponding to the heating element is more within the turbulent flow area of the blade (especially the turbulent flow area of the blade with the lowest blade tip). As a result, the turbulent flow generated by the stirring of the blade has a good stirring effect on the food, making the food more fluid. On the one hand, it makes the food mixed more evenly, and on the other hand, it can better prevent the side of the disc cavity from being stained with food and being burned.
[0024] In a second aspect, the present application discloses a food processor, comprising a drive device and any one of the aforementioned blade disc assemblies, wherein the drive device drives the blade assembly.
[0025] As configured above, the food processor at least has the beneficial effects of the blade assembly, which will not be described in detail. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.
[0037] First, see Figures 4 to 6 , embodiments of the present application disclose two cutterhead assemblies 10 . Figure 4and Figure 5 The first disclosed cutterhead assembly and Figure 6 Compared with the second disclosed cutter disc assembly, the only difference is that the structure of the heating element 2 is different. The cutter disc assembly 10 disclosed in this application includes a disc body 1, a heating element 2 and a cutter assembly 5. In some embodiments, the cutter disc assembly 10 may also not include the heating element 2. The cutter assembly 5 includes a bearing seat 51, a cutter shaft 52 and a blade 53. In this application, the blade 53 includes a first blade 531 and a second blade 532. The first blade 531 and the second blade 532 each have two blades, so that the cutter assembly 5 is a four-blade blade. The number of blades 53 is not limited to this, and in some cases it can also be two blades, three blades, etc. The composition of the disc body 1 is not limited. In the embodiment of the present application, the disc body 1 includes an inner disc body 141 and a heat-conducting disc 142. The heat-conducting disc 142 covers the inner disc body 141, so that the disc body 1 is a double-layer structure. The inner disc body 141 is made of, for example, a food-grade stainless steel disc. The heat-conducting disc 142 can be an aluminum disc that can conduct heat. In some embodiments, the disk body 1 may also be a single-layer structure. Regardless of the structure of the disk body 1, the disk body 1 includes a disk body bottom wall 11 and a disk body side wall 12. The disk body bottom wall 11 is rotatably assembled with the blade shaft 52. An embodiment of the rotational assembly is described as follows: the bearing seat 51 can be welded to the disk body bottom wall 11, and the blade shaft 52 is assembled with the bearing seat 51 through bearings and other components, thereby achieving rotational assembly of the blade shaft 52 and the disk body bottom wall 11. The disk body side wall 12 and the disk body bottom wall 11 form a disk body cavity 13. The disk body cavity 13 includes a disk body cavity bottom surface 131 and a disk body cavity side surface 132. In the above embodiment, the side surface of the inner disk body 141 is the disk body cavity side surface 132, and the bottom surface of the inner disk body 141 is the disk body cavity bottom surface 131. The disk body cavity side surface 132 includes an arc-shaped surface connected to the disk body cavity bottom surface 131 and formed by rotating the arc 1320 around the rotation center line of the blade shaft. The disc cavity side 132 is as follows Figure 5 and Figure 6 In addition to the shape shown, it can also be Figure 9 The center of the arc deviates from the rotation center line of the knife axis. Figure 5 The deviation distance is shown as M.
[0038] As set up above, since the center of the circle corresponding to the arc 1320 deviates from the rotation center line of the blade shaft 52, compared with the case where the center of the circle of the arc 1320 is located on the rotation center line, it is equivalent to that the side surface 132 of the disc cavity is more inclined toward the outside of the blade shaft 52. In this way, on the one hand, the center of the circle of the disc cavity side surface 132 deviates from the rotation center line, and when beating, the food accumulated on the side surface 132 of the disc cavity generates certain small eddies on the side. Such small eddies are different from the large eddies generated around the rotation center line. The small eddies circulate in the up and down directions, which helps to mix the food more evenly. On the other hand, in the process of the blade beating to form turbulence, the water flowability is better, the exchange is faster, and more water enters the bottom edge area of the disc cavity 13 (such as Figure 5 The area indicated by the dotted arrow B in the middle), finally, the food at the bottom edge of the dish cavity can also be fully stirred, and the food is mixed more evenly. In the case where the side wall of the dish is provided with a heating element, because the food at the bottom edge of the dish cavity can also be fully stirred, the food at the bottom edge of the dish cavity is not ignored and can be effectively heated, so that the overall heating efficiency is high. Based on the same principle, the corner between the bearing seat 51 of the knife assembly 5 and the bottom wall 11 of the dish body (such as Figure 5 The food in the area indicated by the dotted arrow b can also be fully stirred to avoid dead corners and make the food more evenly mixed.
[0039] See also Figure 4 The blade assembly 10 of the present application further includes a thermostat 6, a temperature measuring element (such as NTC) 7 and a sealing ring 8. The sealing ring 8 is used to seal the food receiving space formed by the blade body 1 and the mixing cup 20.
[0040] See also Figure 5 In some embodiments, the arc is the brachistochrone curve. Figure 5 As shown, the arc 1320 satisfies the equations: x=R(γ-sinγ)+Mcosγ and y=R(1-cosγ)+Msinγ, wherein x is the horizontal coordinate of a point on the arc 1320, y is the vertical coordinate of a point on the arc 1320; R is the radius of the arc 1320; M is the distance that the center of the circle deviates from the rotation center line along the radial direction of the tool axis; γ is the point on the arc ( Figure 5 The angle between the line connecting the highest point of the arc 1320 and the lowest point of the arc 1320 and the horizontal line passing through the center of the arc is 0≤γ≤π / 2. In the above embodiment, the radius of the opening of the disc cavity 13 is N, and M+R>N.
[0041] As described above, since the arc is the brachistochrone curve, combining this brachistochrone curve with the center of the arc corresponding to the arc offset from the blade axis's rotational center allows food to fall more quickly along the sides of the disc cavity, resulting in greater impact energy from the blades on the food and better mixing of the food and water, resulting in a more even food mix. If the blade disc sidewall 12 is provided with a heating element 2, based on the characteristics of the brachistochrone curve, the blades drive the food-water mixture within the disc cavity 13 to flush the disc cavity side 132 with greater impact force, preventing food from sticking to the disc cavity side 132 and, in turn, preventing the disc cavity side 132 from being burned.
[0042] See also Figure 5 The knife assembly 5 includes a plurality of blades (a first blade 531 and a second blade 532) assembled on the knife shaft 52. On the radial plane of the knife shaft 52, the center O is located in the circle formed by the rotation of the blades; in the axial direction of the knife shaft 52, the plurality of blades include the highest blade tip 5321 and the lowest blade tip 5311, and the center is located between the highest blade tip 5321 and the lowest blade tip 5311.
[0043] As described above, in the radial plane of the blade shaft 52, the center O is located within the circle formed by the rotation of the blades. In the axial direction of the blade shaft 52, the center O is located between the highest blade tip 5321 and the lowest blade tip 5311. This allows the aforementioned small eddies to be different from the large eddies generated around the centerline of rotation, resulting in better water flow and faster water exchange. Furthermore, more water enters the bottom edge of the dish cavity 13, ultimately resulting in more even mixing of the food. In the presence of a heating element, this prevents food from sticking to the sides of the dish cavity, thereby preventing the sides from being burned.
[0044] In some embodiments, the center of the circle O is offset from the rotation centerline by a distance M. Along the axial direction of the blade shaft 52, the distance between the center of the circle and the bottom surface 131 of the disc cavity is H, where 0 < M / H ≤ 1 / 2. The radius of the disc cavity opening is N, where 1 / 3 ≤ M / N ≤ 1 / 2. More specifically, 0 < M ≤ 50 mm. 0 < H ≤ 110 mm.
[0045] As set above, 0<M / H≤1 / 2 and 1 / 3≤M / N≤1 / 2, the turbulence effect generated by the blade can be better, and the food can be mixed more evenly in the end.
[0046] See also Figure 5 and Figure 6The blade assembly 5 includes a bearing seat 51, and the blade shaft 52 is assembled to the bottom wall 11 of the disc body through the bearing seat 51, so that the bearing seat 51 and the bottom wall 11 of the disc body form an intersection 110, the edge of the bottom wall 11 of the disc body is located outside the intersection 110, and the arc 1320 is connected to the edge of the bottom surface 131 of the disc body cavity. The central angle of the arc 1320 is β, 30 degrees ≤ β ≤ 90 degrees, for example, 30 degrees, 35 degrees, 40 degrees, 43 degrees, 47 degrees, 50 degrees, 53 degrees, 55 degrees, 58 degrees, 60 degrees, 63 degrees, 65 degrees, 68 degrees, 70 degrees, 73 degrees, 75 degrees, 78 degrees, 80 degrees, 83 degrees, 85 degrees, 88 degrees or 90 degrees. In other embodiments, that is, the area of the bottom wall 11 of the disc body cavity completely overlaps the area of the projection of the bearing seat 51. In this case, the arc 1320 is connected to the intersection 110, and the central angle corresponding to the arc 1320 is β, 0 degrees < β ≤ 90 degrees, for example, 5 degrees, 10 degrees, 13 degrees, 20 degrees, 23 degrees, 25 degrees, 28 degrees, 30 degrees, 35 degrees, 40 degrees, 43 degrees, 47 degrees, 50 degrees, 53 degrees, 55 degrees, 58 degrees, 60 degrees, 63 degrees, 65 degrees, 68 degrees, 70 degrees, 73 degrees, 75 degrees, 78 degrees, 80 degrees, 83 degrees, 85 degrees, 88 degrees or 90 degrees.
[0047] As set above, 0 degrees ≤ β ≤ 90 degrees, or 30 degrees ≤ β ≤ 90 degrees. This condition, combined with the center of the circle corresponding to the aforementioned arc 1320 deviating from the rotation center line of the knife shaft 52, can achieve a good turbulence effect and more uniform mixing of food.
[0048] See also Figure 5 and Figure 6 The disc side wall 12 includes a side wall top 121 relative to the disc bottom wall 11. The cutter disc assembly includes a heating element 2, which is located at the side wall top 121 and is arranged around the circumference of the disc side wall 12.
[0049] As described above, since the heating element 2 is located at the top end 121 of the side wall and is arranged circumferentially around the side wall 12 of the dish body, the heating element 2 is relatively far from the bottom wall 11 of the dish body. The heat generated by the heating element 2 is transferred to the bottom wall 11 of the dish body through the side wall 12 of the dish body. The bottom surface 131 of the dish body cavity is the inner surface of the bottom wall 11 of the dish body. In this way, the bottom wall 11 of the dish body is heated evenly, and the bottom surface 131 of the dish body cavity is less likely to be burned. In addition, the turbulence generated by the rotation of the blade 53 can drive the food within the dish body cavity 13, which also makes the side surface 132 of the dish body cavity and the bottom surface 131 of the dish body cavity less likely to be burned.
[0050] See also Figure 5 and Figure 6, along the axial direction of the blade shaft 52, the multiple blades 53 include the lowest blade tip 5311, and the distance between the top of the heating element 2 and the bottom surface 131 of the disc cavity is L2. The distance between the lowest blade tip 5311 and the bottom surface 131 of the disc cavity is L1, 0.25≤L1 / L2≤0.75. For example, 0.25, 0.28, 0.3, 0.33, 0.35, 0.38, 0.4, 0.43, 0.45, 0.48, 0.5, 0.52, 0.55, 0.58, 0.6, 0.62, 0.65, 0.68, 0.7, 0.72, 0.73 or 0.75. It should be noted here that, Figure 5 and 6 In the figure, along the axial direction of the blade shaft 52, the lowest blade tip 5311 is located between the top and bottom edges of the contact surface formed by the heating element 2 and the side wall 12 of the disk body. However, when 0.25≤L1 / L2≤0.75, the lowest blade tip 5311 may also be lower than the bottom edge of the contact surface or other situations.
[0051] As set above, since 0.25≤L1 / L2≤0.75, the heating area corresponding to the disc cavity side surface 132 of the disc side wall 12 and the heating element 2 is heated by the heating element 2, and this area is close to the turbulence area of the blade, and the turbulence of the blade (at least the turbulence generated by the blade with the lowest blade tip) acts more effectively on the heating area. The blade has a good stirring effect, which makes the food more fluid. On the one hand, the food is mixed more evenly. On the other hand, the food can be separated from the disc cavity side surface 132 to prevent the disc cavity side surface 132 from being stained by food and being burned. Correspondingly, the disc cavity bottom surface 131 can be prevented from being stained by food and being burned.
[0052] See also Figure 5 and Figure 6 The disc cavity side surface 132 includes a bottom edge connected to the disc cavity bottom surface 131 and a top edge opposite to the bottom edge; the included angle α between the tangent plane S passing through the top edge and the bottom edge and the disc cavity bottom surface 131 is 90 degrees ≤ α ≤ 170 degrees, for example, 90 degrees, 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, 150 degrees, 155 degrees, 160 degrees, 165 degrees or 170 degrees. See Figure 7 , Figure 7 This is a chart based on the following table.
[0053] α 90 95 100 105 110 115 120 125 130 Number of rice 11 8 8 6 2 0 3 5 5 α 135 140 145 150 155 160 165 170 Number of rice 8 7 6 8 9 12 15 14
[0054] exist Figure 7 In the figure, when the angle α is around 105 degrees to 130 degrees, the number of particles sticking to the rice is within 5, and when the angle α exceeds 130 degrees, the number of particles sticking to the rice exceeds 5.
[0055] As described above, when the angle is 90 degrees ≤ α ≤ 170 degrees, the turbulence generated by the blades achieves a good stirring effect and improves the fluidity of the food. On the one hand, it can make the food evenly mixed, and on the other hand, it can prevent the side surface 132 and the bottom surface 131 of the dish cavity from being contaminated and burned. Figure 7 Although the beneficial effects of the heating element 2 are shown, when the heating element 2 is not provided, the blade assembly does not have the beneficial effects associated with the heating element 2, but can still mix the food evenly. In addition, compared with the case where 90 degrees ≤ α ≤ 170 degrees and the diameter of the bottom wall 11 of the disc body is larger than the diameter of the bearing seat 51, the case where 90 degrees ≤ α ≤ 170 degrees and the diameter of the bottom wall 11 of the disc body is larger than the diameter of the bearing seat 51 is changed. By changing the position of the side wall arc to make the arc shorter, it is equivalent to the bottom wall 11 of the disc body being closer to the lowest blade along the axial direction of the blade shaft 52. As a result, the blade can effectively cover the bottom edge area of the disc body cavity 13, reducing dead corners that are not heated or cannot be stirred.
[0056] See also Figure 5 and Figure 6 , the knife assembly 5 includes a plurality of blades 53 assembled with the knife shaft 52. At least part of the plurality of blades 53 is located in the disc body cavity 13, including the following situations: 1) As shown in the figure, the blade includes a highest blade tip 5321 and a lowest blade tip 5311. The highest blade tip 5321 is located outside the disc body cavity 13, and the lowest blade tip 5311 is located inside the disc body cavity 13; 2) The highest blade tip 5321 and the lowest blade tip 5311 are both located inside the disc body cavity 13. In either case, along the radial direction of the knife shaft 52, the distance between the lowest blade tip 5311 of the plurality of blades and the side surface 132 of the disc body cavity is P1; the width of the projection of the side surface 132 of the disc body cavity on the radial plane of the knife shaft 52 is P2, and 0.1≤P1 / P2≤0.6. For example, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, or 0.6. Figure 8 Combined with the following table, Figure 8 The chart is generated based on the following table:
[0057] P1 / P2 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 Number of rice 6 4 2 0 0 3 5 7 P1 / P2 0.5 0.55 0.6 0.65 0.7 Number of rice 11 13 13 18 25
[0058] from Figure 8As can be seen from the above table, when 0.1≤P1 / P2≤0.25, the number of rice sticking shows a downward trend. When the ratio of P1 / P2 is greater than 0.3, the number of rice sticking shows an upward trend. Furthermore, when the ratio is 0.15≤P1 / P2≤0.4, the number of rice sticking is less than or equal to 5, the anti-sticking effect is optimal, and the anti-sticking effect of level 2 is achieved. When the ratio of P1 / P2 is 0.45, the number of rice sticking is 7; at 0.5, the number of rice sticking is 11, when the ratio is 0.55, the number of rice sticking is 13, when the ratio is 0.6, the number of rice sticking is 13, when the ratio is 0.65, the number of rice sticking is 18, and when the ratio is 0.7, the number of rice sticking is 25. In summary, 0.1≤P1 / P2≤0.6.
[0059] As described above, since 0.1≤P1 / P2≤0.6, the distance between the disc cavity side surface 132 and the blade is not too far, so that the turbulence of the blade (at least the turbulence generated by the blade with the lowest blade tip 5311) can more effectively act on the area between the disc cavity side surface 132 and the blade with the lowest blade tip, which has a good stirring effect on the food and improves the fluidity of the food. Thus, on the one hand, the food is mixed more evenly, and on the other hand, when the heating element 2 is provided on the disc side wall 12, the food is prevented from sticking to the disc cavity side surface 132 and being burned. When the heating element 2 is provided, the heating element 2 is arranged circumferentially around the disc side wall 12, first heating the disc side wall 12, and the heat is transferred to the disc bottom wall 11 through the disc side wall 12. The disc bottom wall 11 is evenly heated, and combined with the turbulence generated by the blade, the food has good fluidity, and the disc cavity bottom surface 131 will not stick to the food and be burned. In summary, the above arrangement can avoid the problem of food accumulating at the bottom of the plate due to poor fluidity and becoming sticky, thereby improving the user experience.
[0060] In some embodiments, 3 mm ≤ P1 ≤ 25 mm, for example, 3 mm, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, 17 mm, 20 mm, 22 mm, 24 mm, or 25 mm; 5 mm ≤ P2 ≤ 60 mm, for example, 5 mm, 7 mm, 9 mm, 10 mm, 15 mm, 18 mm, 20 mm, 23 mm, 25 mm, 28 mm, 30 mm, 33 mm, 35 mm, 37 mm, 40 mm, 45 mm, 48 mm, 50 mm, 53 mm, 55 mm, 57 mm, or 60 mm. It will be appreciated by those skilled in the art that at least one of the conditions 3 mm ≤ P1 ≤ 25 mm and 5 mm ≤ P2 ≤ 60 mm is sufficient.
[0061] See also Figure 5 and Figure 6Among the blade tips of the multiple blades, along the axial direction of the blade shaft 52, the lowest blade tip 5311 is located inside the disc cavity 13, and the highest blade tip 5321 is located outside the disc cavity 13. The cutter disc assembly 10 includes a heating element 2, which is arranged around the circumference of the disc side wall 12. The heating element 2 contacts the disc side wall 12 to form a contact surface. Along the axial direction of the blade shaft 52, the lowest blade tip 5311 is located between the top and bottom edges of the contact surface. Figure 6 As shown, the top edge of the contact surface is F, and the bottom edge is f. The tip of the first blade 531 (that is, the lowest tip 5311) is located between the top edge F and the bottom edge f of the contact surface, and the tip of the second blade 532 (the highest tip 5321) is located outside the disc cavity 13.
[0062] As set up as above, since the highest blade tip 5321 is located outside the disc cavity 13, and the lowest blade tip 5311 is located inside the disc cavity 13, and is located between the top edge and the bottom edge of the contact surface, the heating area corresponding to the heating element 2 on the side surface 132 of the disc cavity is more within the turbulent flow area of the blade (especially the turbulent flow area of the blade with the lowest blade tip). As a result, the turbulent flow generated by the stirring of the blade has a good stirring effect on the food, making the food more fluid. On the one hand, it makes the food mixing more even, and on the other hand, it can better prevent the side surface 132 of the disc cavity from being stained with food and being burned.
[0063] Second, see Figure 1 、 Figure 2 and Figure 3 The present application discloses a food processor. The food processor includes a drive device and any one of the aforementioned blade disc assemblies 10, wherein the drive device drives the blade assembly. There is no limitation on how the drive is used, for example, it can be driven by a clutch or magnetically. The drive device can be controlled by a program pre-stored in a control panel. In the case where a heating element is provided on the side wall 12 of the disc body, the food processor further includes a control panel, which controls the heating of the heating element 2. Figures 1 to 3 In the embodiment, the food processor includes a blending cup assembly 100 and a main unit 200. The blending cup assembly 100 and the main unit 200 are separate structures. In addition to the blade assembly 10, the blending cup assembly 100 also includes a blending cup 20, a cup lid 30, a handle 40, and a cup holder 50. The main unit 200 includes the drive device. In other embodiments, the blending cup assembly 100 and the main unit 200 may also be an integrated structure.
