Description

Technical Field

[0001] The present application relates to the technical field of food processing machines, and in particular, to a food processing machine. Background Art

[0002] The food processor beats and crushes the fruits, vegetables and other food materials in the accommodating chamber by setting a motor and setting a crushing blade group connected to the motor in the accommodating chamber. In order to fully beat the food materials, the existing food processors generally assemble together multiple layers of blades with inconsistent tip directions or blade lengths, and stagger the blades of each layer of blades to achieve all-round food beating when the crushing blade group rotates. For example, in the existing patents CN205285938U and CN205234243U, the blades corresponding to the upper blade, the lower blade and the middle blade in the crushing blade group are all staggered relative to the blade shaft, that is, the vertical projections of each blade along the axis of the blade shaft are all at different positions of the blade shaft.

[0003] The staggered arrangement of the above-mentioned blades relative to the blade axis results in a poor ability of the crushing blade group to drive the liquid to flow and rotate. Alternatively, when it is necessary to whip slightly larger pieces of food such as ice cubes, the cutting contact area between the crushing blade group and the same piece of food is smaller at the same time, which can also result in a lower crushing efficiency for large pieces of food, and the food processor is prone to problems such as blade jamming or overheating.

[0004] Therefore, there is an urgent need for a new food processor, whose crushing blade group can drive the liquid and food in the accommodating chamber to rotate with higher efficiency and greater force when driven by a motor to rotate, so as to provide better whipping and crushing effects.

[0036] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings.

[0037] See also Figure 1 , Figure 1 This is a first cross-sectional schematic diagram of a food processing machine 1 shown in one embodiment of the present application; see Figure 2 , Figure 2FIG. 2 is a second cross-sectional schematic diagram of a food processing machine 1 according to an embodiment of the present application. Figure 1 to Figure 2 As shown, the present application provides a food processing machine 1, comprising a machine body 10, a motor 30 and a cutter assembly 20. The machine body 10 has a processing chamber 11, the cutter assembly 20 is arranged in the processing chamber 11 and is located at the bottom of the processing chamber 11; the motor 30 is arranged in the machine body 10, and the cutter assembly 20 is connected to the output shaft of the motor 30 through a cutter shaft 25.

[0038] Specifically, the cutter assembly 20 includes a cutter shaft 25, a primary blade 21, a secondary blade 22, and a tertiary blade 23. The tertiary blade 23 is disposed between the primary blade 21 and the secondary blade 22. One end of the cutter shaft 25 is fixedly connected to the tertiary blade 23, the secondary blade 22, and the primary blade 21 by riveting. Optionally, the cutter shaft 25 of the cutter assembly 20 can be connected to a 390 motor to increase the rotational power of the cutter assembly 20, which is beneficial for crushing harder food such as ice cubes.

[0039] See also Figure 3 , Figure 3 This is a schematic diagram of the overall structure of the tool assembly 20 shown in one embodiment of the present application; see Figure 4 , Figure 4 This is an exploded schematic diagram of a tool assembly 20 shown in one embodiment of the present application. Figures 1 to 4 As shown, the tool assembly 20 includes a primary blade 21, a secondary blade 22, a tertiary blade 23 and a blade shaft 25. The primary blade 21, the secondary blade 22 and the tertiary blade 23 all have a blade shaft riveting hole at the center of the blade root position for riveting to the blade shaft 25. During the assembly process of the tool assembly 20, the secondary blade 22, the tertiary blade 23 and the primary blade 21 are riveted to the blade shaft 25 in sequence through the blade shaft riveting holes they have.

[0040] The primary blade 21 is arranged at the bottom of the processing chamber 11, the secondary blade 22 is arranged between the primary blade 21 and the bottom surface 13 of the processing chamber, and the tertiary blade 23 is arranged between the primary blade 21 and the secondary blade 22. The primary blade 21, the secondary blade 22 and the tertiary blade 23 each have a plurality of blades and a blade root, and the blades of each blade are evenly arranged around the blade root in all directions and are integrally formed with the blade root. The blade root has two opposite surfaces facing the top opening 12 and the bottom surface 13 of the processing chamber respectively, and the two opposite surfaces of the blade root are perpendicular to the axis of the blade shaft 25.

[0041] Specifically, the primary blade 21 has a plurality of primary blades 211, the secondary blade 22 has a plurality of secondary blades 221, and the tertiary blade 23 has a plurality of tertiary blades 231. The primary blades 211 and the secondary blades 221 are aligned one by one along the axis direction of the blade shaft 25, and their projections overlap. The primary blades 211 or the secondary blades 221 and the tertiary blades 231 are arranged in a staggered manner around the axis of the blade shaft 25, that is, the primary blades 211 or the secondary blades 221 and the tertiary blades 231 are arranged in a staggered manner along the axis direction of the blade shaft 25, and their projections are arranged in a staggered manner on the blade shaft 25.

[0042] Based on the above scheme, the multiple primary blades 211 of the primary blade 21 and the multiple secondary blades 221 of the secondary blade 22 are aligned one by one along the axial direction of the blade shaft 25 and the projections overlap, so that the blades of each layer are arranged consistently and aligned along the axis of the blade shaft 25, which can effectively improve the ability of the tool assembly 20 to drive the liquid in the processing chamber 11 to rotate and flow; the present application uses the tertiary blades 231 of the tertiary blade 23 to be arranged in an alternating manner with the primary blades 211 or the secondary blades 221 around the axis of the blade shaft 25, so that the liquid food can be more fully whipped and crushed.

[0043] Specifically, each primary blade 211 has a primary blade 213 on one side, each secondary blade 223 has a secondary blade 223 on one side, and each tertiary blade 231 has a tertiary blade 233 on one side. The primary blade 213, the secondary blade 223, and the tertiary blade 233 have the same cutting direction after the tool assembly 20 is assembled. For example, the tool assembly 20 rotates in the first direction ( Figure 3 When the blade 210 rotates clockwise (as shown in the figure), each of the primary blade 213, the secondary blade 223 and the tertiary blade 233 can cut the food head-on at the same time. Accordingly, the primary blade 213 and the secondary blade 223 are arranged in the same and aligned direction along the axis of the blade shaft 25.

[0044] Based on the above scheme, the primary blade 213 and the secondary blade 223 are arranged and aligned along the axis direction of the blade shaft 25, and the setting of the same cutting direction when the cutter assembly 20 rotates can broaden the cutting range of the cutter assembly 20 for the same large piece of food, that is, at the same time, the cutter assembly 20 can achieve multiple cuts at different positions for the same large piece of food, effectively improving the number of cuts and cutting efficiency. The present application can effectively improve the ability of the cutter assembly 20 to crush and cut large pieces of food, and improve the processing efficiency and processing quality of the food processor 1.

[0045] In one embodiment, the cutter assembly 20 further includes a fourth blade 24, which is disposed between the third blade 23 and the first blade 21, or between the third blade 23 and the second blade 22. Figure 3 , Figure 4As shown, the fourth blade 24 is arranged between the first blade 21 and the third blade 23. The fourth blade 24 has a fourth blade root 242 and a plurality of fourth blades 241 evenly arranged around the center of the fourth blade root 242. The fourth blades 241 and the fourth blade root 242 are integrally formed.

[0046] Specifically, the blade extension surface of each of the four-stage blades 241 is located in the same plane as the blade root extension surface of the four-stage blade root 242, that is, the blade extension surface of the four-stage blade 241 is parallel to or overlaps with the blade root extension surface of the four-stage blade root 242. Further, along the axis direction of the blade shaft 25, the four-stage blade 241 is aligned one by one with the primary blade 211 and the secondary blade 221, and their projections overlap.

[0047] Specifically, one side of the four-stage blade 241 has a four-stage blade 243, and one end of the four-stage blade 243 away from the four-stage blade root 242 is a four-stage blade tip 244. The four-stage blade 243, the first blade 213, the second blade 223 and the third blade 233 have the same cutting direction after assembly. For example, the tool assembly 20 rotates in the first direction ( Figure 3 When the blade 213 rotates clockwise (as shown in the figure), each of the primary blade 213, the secondary blade 223, the tertiary blade 233, and the quaternary blade 243 can cut the food head-on at the same time. Accordingly, the quaternary blade 243, the primary blade 213, and the secondary blade 223 are arranged and aligned along the axis direction of the blade shaft 25.

[0048] Based on the above scheme, the present application increases the number of times the cutter assembly 20 cuts the food material by rotating the six blades of the three-layer blade (or the eight blades of the four-layer blade), and improves the crushing effect of the cutter assembly 20 on the food material. The first-level blade 211, the fourth-level blade 241 and the second-level blade 221 are arranged in a consistent and aligned manner along the axis of the cutter shaft 25, and the third-level blade 231 and the first-level blade 211 are arranged in an interlaced manner around the cutter shaft 25, which can more efficiently and effectively drive the liquid to rotate with it, forming a better liquid tumbling state, which is conducive to improving the whipping and crushing effect of the cutter assembly 20 on the liquid and food material. The present application reasonably arranges the blade and blade positions by stacking multiple blades and assembling the cutter assembly 20, fully and efficiently utilizes the bottom space of the processing chamber 11, increases the contact range with food material and liquid, widens the effective crushing area of ​​the cutter assembly 20, and improves the crushing and stirring ability of the cutter assembly 20.

[0049] See also Figure 5 , Figure 5 FIG. 2 is a cross-sectional schematic diagram of a primary blade 21 according to an embodiment of the present application. Figure 5As shown, the primary blade 21 has multiple primary blades 211 and a primary blade root 212. Each primary blade 211 is bent toward the top opening 12 of the processing chamber 11 relative to the primary blade root 212. The primary blades 211 are evenly arranged around the primary blade root 212 and are integrally formed with the primary blade root 212.

[0050] Specifically, one primary blade 21 has two primary blades 211, which are arranged on opposite sides of the primary blade root 212 and are integrally formed with the primary blade root 212. At least one side of the primary blade 211 has a primary blade edge 213, and the end of the primary blade edge 213 away from the primary blade root 212 is a primary blade tip 214. The bending angle α1 of the primary blade 211 relative to the primary blade root 212 is in the range of 100°-150°. Based on the above scheme, the present application sets the primary blade 211 to bend toward the top opening 12 of the processing chamber 11 relative to the primary blade root 212, so that the food thrown up during processing or the food moving with the shaking of the food processor (such as ice cubes) can be crushed by the upturned blade tip and blade, so as to further enhance the crushing ability of the primary blade 21 and reduce the impact force on the tool assembly 20 when the food falls from a high place.

[0051] In one embodiment, each primary blade 211 is provided with cutting edges on both sides of the blade tip (i.e., the primary blade tip 214) to increase the effective cutting range of the primary blade 21 on food falling from a high place in the processing chamber 11, thereby improving the food processor 1's crushing efficiency and crushing quality.

[0052] Based on the above scheme, the present application can directly beat and crush the food (such as ice cubes) in the processing chamber 11 that is driven by the tool assembly 20 to rotate, shake or throw toward the top opening and then fall, by using the primary blade 213 and the primary blade tip 214 that are tilted toward the top opening 12, while reducing the impact force of the falling food on the tool assembly 20, thereby improving the working stability and reliability of the food processor 1.

[0053] See also Figure 6 , Figure 6 FIG. 2 is a cross-sectional schematic diagram of a secondary blade 22 according to an embodiment of the present application. Figure 6 As shown, the secondary blade 22 has multiple secondary blades 221 and a secondary blade root 222. Each secondary blade 221 is bent toward the bottom surface 13 of the processing cavity relative to the secondary blade root 222. Each secondary blade 221 is evenly arranged around the secondary blade root 222 and is integrally formed with the secondary blade root 222.

[0054] Specifically, a secondary blade 22 has two secondary blades 221, and the two secondary blades 221 are respectively arranged on opposite sides of the secondary blade root 222, and are integrally formed with the secondary blade root 222. At least one side of the secondary blade 221 has a secondary blade edge 223 (only one side of the secondary blade 221 is shown with a secondary blade edge 223 in the drawings of the present application), and the end of the secondary blade edge 223 away from the secondary blade root 222 is a secondary blade tip 224, and the bending angle α2 of the secondary blade 221 relative to the secondary blade root 222 is 150°-170°. Based on the above scheme, the present application stirs the food falling on the bottom of the processing chamber 11 by setting the secondary blade 221 to bend toward the bottom surface 13 of the processing chamber relative to the secondary blade root 222, and brings the food out of the bottom to continue to roll with the liquid, thereby further improving the crushing and cutting effect of the tool assembly 20.

[0055] Based on the above scheme, by bending the secondary blade 221 relative to the secondary blade root 222 toward the bottom surface 13 of the processing chamber, the tool assembly 20 can further stir the food that falls to the bottom of the processing chamber 11 through the secondary blade 223; at the same time, the oblique blade surface of the secondary blade 223 is arranged toward the top opening 12, which can further assist the secondary blade 221 to lift up the food that falls to the bottom of the processing chamber 11 and continue to roll it, so that the food can be further cut by the various blades of the rotating tool assembly 20.

[0056] See also Figure 7 , Figure 7 FIG. 2 is a cross-sectional schematic diagram of a three-stage blade 23 according to an embodiment of the present application. Figure 7 As shown, the tertiary blade 23 has a plurality of tertiary blades 231 and a tertiary blade root 232, and each tertiary blade 231 is bent relative to the tertiary blade root 232 toward the bottom surface 13 or the top opening 12 of the processing cavity, that is, at least one tertiary blade 231 is bent relative to the tertiary blade root 232 toward the top opening 12 of the processing cavity 11, and at least one tertiary blade 231 is bent relative to the tertiary blade root 232 toward the bottom surface 13 of the processing cavity; each tertiary blade 231 is evenly arranged around the tertiary blade root 232, and is integrally formed with the tertiary blade root 232.

[0057] Specifically, the tertiary blade 23 has two tertiary blades 231 arranged opposite to each other, that is, the tertiary blade 23 has: one tertiary blade 231 bent toward the bottom surface 13 of the processing chamber relative to the tertiary blade root 232, and one tertiary blade 231 bent toward the top opening 12 of the processing chamber 11 relative to the tertiary blade root 232. The value range of the bending angle α3 of each tertiary blade 231 and the tertiary blade root 232 at the connection is 150°-170°, that is, the bending angle α3 of the tertiary blade 231 relative to the tertiary blade root 232 (bending toward the top opening 12 or bending toward the bottom surface) is 150°-170°. Based on the above scheme, the two tertiary blades 231 of the tertiary blade 23 are bent toward the top opening 12 and the bottom surface 13 of the processing chamber respectively, which can form a larger whipping space and is more conducive to turbulence; the tertiary blades 231 bent toward the bottom surface 13 of the processing chamber can also lift the bottom food and roll it upwards. The present application can improve the whipping and crushing efficiency and whipping and crushing quality of the tool assembly 20 for liquid food.

[0058] In one embodiment, the vertical distance between each tertiary blade tip 234 and the axis of the blade shaft 25 is greater than the vertical distance between the primary blade tip 214, the secondary blade tip 224, or the quaternary blade tip 244 and the axis of the blade shaft 25. Figure 7 As shown, optionally, the length L3 of the tertiary blade 231 is 75mm-95mm, that is, the vertical span distance L3 between the two tertiary blade tips 234 of the tertiary blade 231 is 75mm-95mm. Further, the vertical distance D1 between the tertiary blade tip 234 and the inner wall of the processing chamber 11 is 5mm-15mm. The length L3 of the tertiary blade 231 and the vertical distance D1 between the tertiary blade tip 234 and the inner wall of the processing chamber 11 are determined according to the minimum inner diameter of the processing chamber 11 at the installation area of ​​the tertiary blade 23, and / or the length of the primary blade 21 or the secondary blade 22 or the quaternary blade 24, and / or the actual set speed of the tool assembly 20 when the food processor 1 is running, so as to avoid the tertiary blade 23 from touching the inner wall of the processing chamber 11 during rotation, and to ensure the crushing effect of the tertiary blade 23 on the food in the processing chamber 11, and no strict restrictions are made here.

[0059] Based on the above scheme, the tertiary blade 231 can provide a larger cutting range and is conducive to turbulence by setting the length of the tertiary blade 233 to be greater than the length of the primary blade 213, the length of the quaternary blade 243 or the length of the secondary blade 223, so as to further achieve sufficient crushing of the food and further sufficient stirring of the liquid food by the tool assembly 20.

[0060] In one embodiment, the vertical distance between the tertiary blade tip 234 and the top opening 12 of the processing chamber 11 is 80 mm-120 mm, and the primary blade tip 214 is closer to the top opening 12 in the axial direction of the blade shaft 25 than the tertiary blade tip 234. The vertical distance between the tertiary blade tip 234 and the top opening 12 of the processing chamber 11 is in a range such that the volume of the processing chamber 11 can meet the food accommodating requirements and the lifting height requirements when the food processor 1 crushes food, and can be fully and efficiently utilized, and is not strictly limited to the above numerical range.

[0061] In one embodiment, the tertiary blade tip 234 of the tertiary blade 231 bent toward the bottom surface 13 of the processing chamber is closer to the bottom surface 13 of the processing chamber than the secondary blade tip 224 along the axial direction of the blade shaft 25. Optionally, the vertical distance between the tertiary blade tip 234 of the tertiary blade 231 bent toward the bottom surface 13 of the processing chamber and the bottom surface 13 of the processing chamber is in the range of 5mm-10mm. The vertical distance is in the range of 5mm-10mm, so that the tertiary blade 23 does not touch the bottom surface 13 of the processing chamber when rotating, and can fully stir the food in the processing chamber 11, and is not strictly limited to the above numerical range.

[0062] In one embodiment, the tertiary blade 233 of the tertiary blade 231 extends in an arc shape, and from the tertiary blade root 232 to the tertiary blade tip 234, the arc extension direction of the tertiary blade 233 is opposite to the cutting direction of the primary blade 213. Based on the above scheme, the tertiary blade 231 can achieve the maximum extension of the length of the tertiary blade 233 within a limited accommodation space (i.e., within a limited inner diameter of the processing cavity and a limited height space) to increase the cutting length and cutting range; the setting of the arc blade can provide cutting forces in more directions when the tertiary blade 23 rotates. Therefore, the tertiary blade 23 provided by the present application can increase the cutting range.

[0063] In summary, the food processor 1 provided in the present application can effectively improve processing efficiency and processing quality, enhance processing stability and reliability, and is simple to assemble and saves costs.

Figures 8 to 10As shown, the tool assembly 20 includes two layers of blades, namely, a first-level blade 21 and a fifth-level blade 26. The fifth-level blade 26 is arranged between the first-level blade 21 and the bottom surface 13 of the processing cavity. During the tool assembly process, the first-level blade 21 and the fifth-level blade 26 are riveted to the top of the tool shaft 25 through the tool shaft riveting hole in the center of the tool root.

[0065] The primary blade 21 has a plurality of primary blades 211 and a primary blade root 212. Each primary blade 211 is evenly arranged around the primary blade root 212 and is integrally formed with the primary blade root 212. Each primary blade 211 is bent relative to the primary blade root 212 toward the top opening 12 of the processing chamber 11, and the bending angle α1 is 100°-150°. In one embodiment, the primary blade 21 has four primary blades 211, and at least one side of each primary blade 211 has a primary blade edge 213, and the end of the primary blade edge 213 away from the primary blade root 212 is a primary blade tip 214.

[0066] The five-level blade 26 has a plurality of secondary blades 221, a plurality of tertiary blades 231 and a fifth blade root 260. Each of the secondary blades 221 is bent relative to the fifth blade root 260 toward the bottom surface 13 of the processing cavity, at least one tertiary blade 231 is bent relative to the fifth blade root 260 toward the top opening 12 of the processing cavity 11, and at least one tertiary blade 231 is bent relative to the fifth blade root 260 toward the bottom surface 13 of the processing cavity, and the bending angle α3 is in the range of 150°-170°.

[0067] Based on the above solution, the two third-level blades 231 of the third-level blade 23 are bent toward the top opening 12 of the processing chamber 11 and the bottom surface 13 of the processing chamber, respectively, to form a larger whipping space, which is more conducive to turbulence; the third-level blade 231 bent toward the bottom surface 13 of the processing chamber can bring the bottom food up and roll it upward to achieve further cutting and crushing. This application can improve the whipping and crushing efficiency and whipping and crushing quality of the cutter assembly 20 for liquid food.

[0068] In one embodiment, the five-level blade 26 has two secondary blades 221 and two tertiary blades 231 (the five-level blade 26 can be regarded as a combination of the secondary blade 22 and the tertiary blade 23 in the above embodiment, and its secondary blade root 222 and the tertiary blade root 232 are the same blade root, and it has the advantages of the secondary blade 22 and the tertiary blade 23), the two tertiary blades 231 are respectively arranged on the opposite sides of the five-level blade root 260, one secondary blade 221 is located between the two tertiary blades 231, and the two secondary blades 221 are respectively arranged on the opposite sides of the five-level blade root 260, and each secondary blade 221, each tertiary blade 231 and the five-level blade root 260 are integrally formed. Each of the three-level blades 231 has a three-level blade edge 233, and one end of the three-level blade edge 233 away from the five-level blade root 260 is a three-level blade tip 234. The vertical span distance L2 between the three-level blade tips 234 of two three-level blades 231 (the vertical direction is parallel to the top surface of the five-level blade root 260) is in the range of 75-95 mm. Optionally, the three-level blade edge 233 is an arc blade, and the extension direction of the arc blade is opposite to the cutting direction of the two-level blade edge 223; the vertical span distance between the two three-level blade tips 234 is greater than the vertical span distance between the two secondary blade tips 224.

[0069] Based on the above scheme, the tertiary blade 231 can provide a larger cutting range by setting the length of the tertiary blade 233 to be greater than the length of the primary blade 213 or the length of the secondary blade 223, and the setting of the tertiary blade 233 as an arc blade, so as to further achieve the sufficient crushing of the food and sufficient stirring of the liquid food by the tool assembly 20.

[0070] In one embodiment, the primary blade 211 of the primary blade 21 and the secondary blade 221 of the fifth blade 26 are aligned one by one along the axis of the blade shaft 25 and their projections overlap; the primary blade 213 of the primary blade 21 and the secondary blade 223 and the tertiary blade 233 of the fifth blade 26 have the same cutting direction. Based on the above scheme, the present application can effectively improve the ability of the tool assembly 20 to drive the liquid in the processing chamber 11 to rotate and flow, and can make the liquid food more fully whipped and crushed.

[0071] Based on the above solution, the present application adopts a solution of stacking two layers of blades to form an eight-leaf knife, making the assembly of the knife assembly 20 more convenient and efficient, and effectively reducing costs. The double-layer eight-leaf knife provided in the present application can also more efficiently and fully whip liquids and crush ingredients, so as to further improve the working efficiency and work quality of the food processor 1.
