Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with good juicing effect. Background Technology

[0002] Existing food processing machines, such as juicers and slow juicers, typically include a main unit with a built-in motor and a juicing component located above the main unit. The juicing component includes a juicing body located above the main unit and a hopper located above the juicing body. The juicing body includes a juicing screen forming the juicing chamber and a juice collection tray located outside the juicing screen. When using a slow juicer, the user puts fruits and vegetables into the hopper. As the motor drives the squeezing component in the juicing chamber to rotate, the food is squeezed to extract juice in the juicing chamber. The squeezed pulp is discharged out through the pulp outlet. However, because the squeezed fruit and vegetable fibers are long and coarse, direct discharge can easily cause blockage if the discharge port is small. To improve the smoothness of discharge, Chinese utility model patent CN202121806425.3 discloses a crushing and squeezing component for a large-diameter juicer. It has squeezing ribs formed on the inner wall of the lower part of the filter screen. When the fruit pulp moves downward with the screw, the screw and the squeezing ribs cooperate to grind and squeeze the fruit pulp to cut it. Another patent CN201821697569.8 discloses an improved juicer, which has cup cutting ribs and cup grinding ribs interlaced on the circumferential wall of the juicing cup. Because the upper part of the cup cutting ribs is far from the inner wall of the juicing cup, the fruit is cut under the pushing action of the screw head. When the chunks of fruit are cut into smaller chunks, the fruit slides down. Because the distance between the cup grinding ribs and the screw head is shorter, the fruit can be ground and squeezed. Although both of the above methods can grind fruit pulp, in actual use, especially when extracting high-fiber foods such as celery, the grinding effect of the grinding ribs is poor. The fruit and vegetable fibers become entangled and easily block the pulp outlet, causing the pulp to be unable to be discharged smoothly, which in turn interrupts the food processing and seriously affects the consumer's user experience. Utility Model Content

[0003] The purpose of this invention is to provide a food processing machine with good juicing effect, which solves the problem that the grinding ribs in existing food processing machines cannot meet the grinding requirements of high-fiber fruits and vegetables, resulting in the fruit and vegetable fibers becoming entangled and unable to be discharged smoothly.

[0004] To achieve the above objectives, this utility model provides a food processing machine with good juicing effect, including a main unit;

[0005] A juicing mesh, mounted on the main unit, includes a juicing section and an upper limit ring located below the juicing section;

[0006] A juice collection tray is installed on the main unit and is inserted into the juice extraction mesh to form a juice extraction chamber.

[0007] The juice collection tray is provided with an inwardly protruding lower limiting ring at the bottom. The bottom wall of the upper limiting ring abuts against the top wall of the lower limiting ring. A second grinding rib is formed on the inner side wall of the lower limiting ring, and the bottom of the screw cooperates with the second grinding rib.

[0008] This application achieves this by having the screw directly engage with the lower limiting ring in the grinding area below the juicing mesh, eliminating intermediate parts and unnecessary assembly gaps. The space between the lower limiting ring and the screw is highly compact, increasing the friction on the material. A second grinding rib is added to the grinding area within the axial height range of the lower limiting ring to further enhance the squeezing action between the screw and the lower limiting ring, thereby further increasing the friction on the material. This allows high-fiber ingredients, such as celery, to be coarsely ground in the grinding area above the bottom of the juicing mesh, and then further ground by the squeezing action of the second grinding rib and the screw, extending the grinding path. It can effectively cut food fibers and improve juicing effect. At the same time, when the material passes through two adjacent second grinding ribs, there is a lower limit ring sidewall of a concave section in the middle. When the material runs between the second grinding ribs and the concave section, a pressure difference is generated. High-fiber ingredients that are not easy to juice through grinding are fully juiced by pressure difference. In addition, the pressure difference also helps to scrape off the material and avoid the problem of residue sticking to the wall, thus preventing the problem of high fiber being difficult to discharge after juicing and causing clogging. Furthermore, the second grinding ribs set on the inner sidewall of the juice collection plate can also improve the strength of the juice collection plate, ensuring that the juice collection plate can withstand greater extrusion pressure and helping to extend the service life of the juice collection plate.

[0009] Preferably, the inner wall of the upper limit ring is formed with a first grinding rib, which is located axially above the second grinding rib.

[0010] By providing grinding ribs on the inner walls of the upper and lower limit rings, a segmented design of the grinding ribs is achieved. During food processing, a first grinding area is formed between the screw and the first grinding rib, and a second grinding area is formed between the screw and the second grinding rib. On the one hand, this allows high-fiber foods such as celery to undergo a first grinding in the first grinding area and then a second grinding in the second grinding area, effectively cutting the food fibers and improving the juicing effect. At the same time, it allows finely ground pulp to be discharged smoothly, helping to improve pulp discharge efficiency and avoiding the situation where coarse fibers after juicing are difficult to discharge or even cause blockage. On the other hand, it allows some of the food ground at the bottom of the juicing mesh to be transferred to the juice collection tray for further grinding, thereby effectively reducing the squeezing and clamping force between the screw and the juicing mesh. This makes it easier and faster for users to disassemble the screw and other components, improving the user experience.

[0011] Preferably, the first grinding rib and the second grinding rib are offset in the circumferential direction.

[0012] By vertically offsetting the first and second grinding ribs, the fruit residue after being ground by the first grinding ribs can be ground by the second grinding ribs corresponding to each first grinding rib as the screw continues to move forward and downward. This effectively increases the relative distribution density of the first and second grinding ribs, thereby increasing the degree of grinding and extrusion of the food, effectively cutting the food fibers, and helping to further improve grinding efficiency.

[0013] Preferably, the juicing section comprises multiple slots located on the side wall of the juicing mesh, with each slot spaced apart, and the first grinding rib being offset from the slot.

[0014] By misaligning the first grinding rib with the slot, the first grinding rib can be located in front of the screw rotation direction of the corresponding slot. This allows the fruit pulp squeezed by the screw and the juicing section to be ground by the corresponding first grinding rib in each slot as the screw continues to move forward and downward, which helps to further improve grinding efficiency.

[0015] Preferably, a first grinding rib is formed on the inner wall of the upper limit ring, a first grinding area is formed between the screw and the first grinding rib, and a second grinding area is formed between the screw and the second grinding rib, which is connected to the first grinding area.

[0016] By setting up two interconnected grinding zones, high-fiber ingredients such as celery can be ground in the first grinding zone and then further ground in the second grinding zone. This effectively cuts the food fibers, improves the juicing effect, and allows finely ground pulp to be discharged smoothly, which helps improve the pulp discharge efficiency and avoids the situation where coarse fibers after juicing are difficult to discharge or even cause blockage. On the other hand, some of the ingredients ground at the bottom of the first grinding zone can be transferred to the second grinding zone for further grinding, thereby effectively reducing the squeezing and clamping force between the screw and the juicing screen.

[0017] Preferably, the inner wall of the upper limit ring is formed with a first grinding rib, and the distance between the first grinding rib and the central axis of the juicing chamber is less than the distance between the second grinding rib and the central axis of the juicing chamber.

[0018] By setting the distance between the first grinding rib and the central axis of the juicing chamber to be less than the distance between the second grinding rib and the central axis of the juicing chamber, when the fruit pulp is ground at the first grinding rib and then enters the second grinding rib for further grinding, the increased distance between the second grinding rib and the neutral line of the juicing chamber (i.e., the increased distance between the second grinding rib and the outer wall of the screw) significantly reduces the extrusion pressure at the second grinding rib, allowing the fruit pulp to be smoothly discharged through the discharge port and further improving the discharge efficiency.

[0019] Preferably, the side wall of the juice collection tray is concave to form the lower limiting ring; or, the bottom wall of the juice collection tray is convex to form the lower limiting ring.

[0020] Preferably, the inner wall of the upper limit ring is formed with a first grinding rib, the top surface of the upper limit ring is an inclined surface extending downward, and the first grinding rib includes an inclined section provided on the inclined surface and a vertical section provided on the inner side wall of the upper limit ring.

[0021] By making the top surface of the upper limit ring a downward-sloping surface, the pulp can move more smoothly downwards towards the upper limit ring during juicing, effectively preventing the pulp from getting stuck and accumulating if the top surface of the upper limit ring is horizontal. This ensures smooth food processing. Simultaneously, the first grinding rib includes an inclined section on the inclined surface and a vertical section on the inner wall of the upper limit ring, allowing the pulp to begin grinding on the inclined section. This initial cutting facilitates smoother downward movement, while further grinding via the vertical section further improves grinding efficiency.

[0022] Preferably, the distance between the first grinding rib and the central axis of the juicing chamber is L1, and the distance between the second grinding rib and the central axis of the juicing chamber is L2, wherein L1 and L2 satisfy: 0.2mm≤L2-L1≤0.6mm.

[0023] By setting L1 and L2 to satisfy: 0.2mm≤L2-L1≤0.6mm, we can avoid the situation where L2 is relatively smaller than L1, resulting in a smaller distance between the second grinding rib and the screw, causing the fruit residue to be subjected to greater extrusion pressure at the second grinding rib, which would prevent the fruit residue from being discharged smoothly. At the same time, we can also avoid the situation where L2 is relatively larger than L1, resulting in a larger distance between the second grinding rib and the screw, which would prevent the fruit residue from being effectively cut, and thus cause the fruit residue to be discharged unsmoothly or even blocked.

[0024] Preferably, the inner wall of the upper limit ring is formed with a first grinding rib, and the height H1 of the first grinding rib and the height H2 of the second grinding rib satisfy: 0.63≤H1 / H2≤0.93.

[0025] By setting the relationship between H1 and H2 to 0.63≤H1 / H2≤0.93, that is, the height of the first grinding rib is at least half the height of the second grinding rib, it is ensured that the height range of the first grinding rib can fully grind materials with larger particle sizes. At the same time, it also ensures that the lower limit ring can fully bear the grinding task within the height range of the second grinding rib. The grinding task is reasonably decomposed vertically and vertically, the grinding path is extended, and the material can be effectively finely ground and fully extracted. This not only greatly improves the juice yield, but also makes the particle size smaller after the material is finely ground between the second grinding rib and the screw, and it is not easy to clog the slag, thus avoiding radial disturbance of the screw.

[0036] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0037] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0038] like Figures 1 to 7 As shown, this utility model discloses a food processing machine with good juicing effect, including: a main unit 1; a juicing mesh 2, disposed on the main unit, including a juicing part and an upper limit ring 42 disposed below the juicing part; a juice collection tray 6, installed on the main unit, and inserted and cooperated with the juicing mesh to form a juicing chamber; wherein, the bottom of the juice collection tray is also provided with an inwardly protruding lower limit ring 62, the bottom end of the juicing mesh abuts against the top wall of the lower limit ring, a second grinding rib is formed on the inner side wall of the lower limit ring, and the bottom of the screw 5 cooperates with the second grinding rib 61.

[0039] It should be noted that "bottom of juice collection tray 6" refers to the part below the bottom of juice extraction mesh 2, with the bottom surface of juice extraction mesh 2 as the boundary.

[0040] Understandably, in the grinding area below the juicing mesh 2, the screw 5 directly engages with the lower limit ring. There are no other intermediate parts between the lower limit ring and the screw 5, and no extra assembly gaps. The space between the lower limit ring 62 and the screw 5 is highly compact to increase the friction on the material. In the grinding area within the axial height range of the lower limit ring, a second grinding rib 61 is added to further enhance the squeezing effect between the screw and the lower limit ring, thereby increasing the friction on the material. This allows high-fiber ingredients such as celery to be coarsely ground in the grinding area above the bottom surface of the juicing mesh before being further ground in the second grinding area. The ribs and screw extrusion further grind the material, extending the grinding path and effectively cutting the food fibers to improve the juicing effect. At the same time, when the material passes through two adjacent second grinding ribs 61, there is a lower limit ring sidewall of a recessed section in the middle. When the material runs between the second grinding ribs and the recessed section, a pressure difference is generated, which also helps to scrape the material off and avoid the problem of residue sticking to the wall, thus preventing the problem of fiber blockage after juicing. In addition, the second grinding ribs on the inner sidewall of the juice collection plate can also improve the strength of the juice collection plate, ensuring that the juice collection plate 6 can withstand greater extrusion pressure and helping to extend the service life of the juice collection plate.

[0041] Secondly, by providing an inwardly protruding lower limiting ring 62 at the bottom of the juice collecting tray 6, and with the bottom end of the juicing mesh 4 abutting against the top wall of the lower limiting ring 62, the juice collecting tray 6 achieves axial positioning of the juicing mesh 4 with the help of the lower limiting ring 62, ensuring the stability of the cooperation between the juice collecting tray 6 and the juicing mesh 4. Furthermore, while positioning the juicing mesh 4, the lower limiting ring 62 also facilitates the formation of the second grinding rib 61, bringing the second grinding rib 61 closer to the juicing mesh 4. This allows for a smoother transition of fruit pulp between the juicing mesh and the second grinding rib 61, further improving grinding efficiency and preventing high-fiber ingredients from getting stuck or even blocked between them.

[0042] As a preferred embodiment of this application, the food processor with good juicing effect also includes a juicing assembly 2 that cooperates with the main unit 1. The juicing assembly 2 includes a juicing body and a hopper 3 located above the juicing body. The juicing body includes a juice collection plate 6 and a juicing mesh 4 inserted above the juice collection plate 6 to form a juicing chamber. The juicing chamber wall is provided with grinding ribs. The grinding ribs include a first grinding rib 41 located on the inner side wall of the bottom of the juicing mesh 4 and a second grinding rib 61 located on the inner side wall of the juice collection plate 6. The juicing mesh includes an upper limit ring 42 located below the juicing part. The inner wall of the upper limit ring 42 is formed with a first grinding rib 41. The first grinding rib 41 is located axially above the second grinding rib 61.

[0043] By providing grinding ribs on the inner walls of the upper limit ring 42 and the lower limit ring 62, a segmented design of the grinding ribs is achieved. During food processing, a first grinding area is formed between the screw 5 and the first grinding rib 41, and a second grinding area is formed between the screw 5 and the second grinding rib 61. This allows high-fiber foods such as celery to be ground in the first grinding area and then further ground in the second grinding area, effectively cutting the food fibers and improving the juicing effect. Simultaneously, it allows finely ground pulp to be smoothly discharged, improving pulp discharge efficiency and preventing coarse fibers from remaining after juicing. This design addresses two issues: firstly, it prevents material from being difficult to drain or even causing blockages; secondly, the segmented grinding ribs prevent material from concentrating on the juicing mesh, which would exert significant pressure on it. Furthermore, the mesh has slots, which greatly reduces its resistance to deformation. If all the grinding ribs were placed on the mesh, it would deform due to excessive pressure. Additionally, the design allows some of the material being ground at the bottom of the mesh to be transferred to the collection tray 6 for further grinding, effectively reducing the clamping force between the screw 5 and the mesh 4. This makes disassembling the screw 5 and other components easier and faster, improving the user experience. Moreover, the inclusion of a second grinding rib 61 on the inner wall of the collection tray 6 increases its strength, ensuring it can withstand greater pressure and extending its lifespan.

[0044] like Figure 6 As shown, the first grinding rib 41 is disposed on the upper limit ring 42. By configuring the juicing net 4 to include a juicing part and an upper limit ring 42 located below the juicing part and protruding inward, and with the first grinding rib 41 disposed on the upper limit ring 42, the juicing part cooperates with the screw 5 to juice the food. At the same time, the upper limit ring 42 can abut against the juice collection plate 6 to achieve axial and radial positioning of the juicing net 4 and the juice collection plate 6, ensuring the stability of the cooperation between the juice collection plate 6 and the juicing net 4. Furthermore, while positioning with the juice collection plate 6, the upper limit ring 42 can also form the first grinding rib 41, making the first grinding rib 41 closer to the juice collection plate 6. This allows the pulp to transition more smoothly between the first grinding rib 41 and the second grinding rib 61, which helps to further improve grinding efficiency and avoids the pulp getting stuck or even blocked between the two.

[0045] Specifically, a first grinding rib is formed on the inner wall of the upper limit ring, a first grinding area is formed between the screw and the first grinding rib, and a second grinding area is formed between the screw and the second grinding rib, which is connected to the first grinding area.

[0046] Understandably, by setting up two interconnected grinding zones, high-fiber ingredients such as celery can be ground in the first grinding zone and then further ground in the second grinding zone. This effectively cuts the fiber, improves the juicing effect, and allows finely ground pulp to be discharged smoothly, thus improving the pulp discharge efficiency and preventing the coarse fibers after juicing from causing difficulty in discharge or even blockage. On the other hand, it allows some of the ingredients ground at the bottom of the first grinding zone to be transferred to the second grinding zone for further grinding, thereby effectively reducing the squeezing and clamping force between the screw and the juicing mesh.

[0047] Furthermore, such as Figure 4 , Figure 5 , Figure 6 As shown, the top surface of the upper limit ring 42 is an inclined surface extending downwards, and the first grinding rib 41 includes an inclined section 411 disposed on the inclined surface and a vertical section 412 disposed on the inner sidewall of the upper limit ring 42.

[0048] By making the top surface of the upper limit ring 42 an inclined surface extending downwards, the pulp can move more smoothly downwards when it moves towards the upper limit ring 42 in the juicing section, effectively avoiding the situation where the top surface of the upper limit ring 42 is a horizontal surface, causing the pulp to get stuck at the top surface of the upper limit ring 42 and unable to move downwards, resulting in pulp accumulation and inability to be discharged, thus ensuring smooth food processing. At the same time, the first grinding rib 41 includes an inclined section 411 provided on the inclined surface and a vertical section 412 provided on the inner side wall of the upper limit ring 42, so that the pulp can begin to be ground at the inclined section 411, allowing it to be initially cut and move downwards more smoothly, and further ground by the vertical section 412, which helps to further improve grinding efficiency.

[0049] It should be noted that this application does not specifically limit the relative positional relationship between the first grinding rib 41 and the juicing part. As a preferred embodiment of this application, the juicing part consists of multiple slots 43 provided on the side wall of the juicing net 4, with each slot 43 spaced apart, and the first grinding rib 41 and the slots 43 are staggered.

[0050] By misaligning the first grinding rib 41 with the slot 43, the first grinding rib 41 can be located in front of the screw 5 in the rotation direction of the corresponding slot 43. This allows the fruit pulp squeezed by the screw 5 and the juicing section to be ground by the first grinding rib 41 corresponding to each slot 43 as the screw 5 continues to move forward and downward, which helps to further improve grinding efficiency.

[0051] It should be noted that this application does not specifically limit the forming method of the lower limit ring 62, which can be any of the following embodiments:

[0052] Example 1: As Figure 7 As shown, in this embodiment, the sidewall of the juice collection tray 6 is recessed to form a lower limiting ring 62.

[0053] Example 2: In this example, the bottom wall of the juice collection plate 6 protrudes to form a lower limiting ring 62.

[0054] It should be noted that this application does not specifically limit the relative positional relationship between the first grinding rib 41 and the second grinding rib 61. As a preferred embodiment of this application, such as... Figure 2 As shown, the first grinding rib 41 and the second grinding rib 61 are vertically staggered and at different axial heights. The first grinding rib 41 is above the second grinding rib 61. The first grinding rib 41 and the second grinding rib 61 are staggered in the circumferential direction. A second grinding rib 61 is provided between two first grinding ribs 41 in the circumferential direction, and vice versa.

[0055] By vertically offsetting the first grinding rib 41 and the second grinding rib 61, the fruit residue after being ground by the first grinding rib 41 can be ground by the second grinding rib 61 corresponding to each first grinding rib 41 as the screw 5 continues to move forward and downward. This effectively increases the relative distribution density of the first grinding rib 41 and the second grinding rib 61, thereby increasing the degree of grinding and extrusion of the food, effectively cutting the food fibers, and helping to further improve grinding efficiency.

[0056] As a preferred embodiment of this application, such as Figure 5 As shown, the distance between the first grinding rib 41 and the central axis of the juicing chamber is less than the distance between the second grinding rib 61 and the central axis of the juicing chamber.

[0057] By setting the distance between the first grinding rib 41 and the central axis of the juicing chamber to be less than the distance between the second grinding rib 61 and the central axis of the juicing chamber, when the fruit pulp is ground at the first grinding rib 41 and then enters the second grinding rib 61 for further grinding, the increased distance between the second grinding rib 61 and the neutral line of the juicing chamber (i.e., the increased distance between the second grinding rib 61 and the outer wall of the screw 5) significantly reduces the extrusion pressure at the second grinding rib 61, allowing the fruit pulp to be smoothly discharged through the discharge port and further improving the discharge efficiency.

[0058] It should be noted that this application does not specifically limit the distance relationship between the first grinding rib 41 and the second grinding rib 61 and the central axis of the juicing chamber. As a preferred embodiment of this application, the distance between the first grinding rib 41 and the central axis of the juicing chamber is L1, and the distance between the second grinding rib 61 and the central axis of the juicing chamber is L2, wherein L1 and L2 satisfy: 0.2mm≤L2-L1≤0.6mm.

[0059] By setting L1 and L2 to satisfy: 0.2mm≤L2-L1≤0.6mm, we avoid the situation where L2 is relatively smaller than L1, resulting in a smaller distance between the second grinding rib 61 and the screw 5, causing the fruit residue to be subjected to greater extrusion pressure at the second grinding rib 61, which in turn prevents the fruit residue from being discharged smoothly; at the same time, we avoid the situation where L2 is relatively larger than L1, resulting in a larger distance between the second grinding rib 61 and the screw 5, which in turn prevents the fruit residue from being effectively cut, which in turn leads to uneven or even blocked discharge of the fruit residue.

[0060] More preferably, the distance L3 between the side wall of the juicing mesh 4 and the side wall of the screw 5 is 1.46-1.66 mm, specifically, L3 = 1.5 mm or 1.6 mm; the distance L4 between the side wall of the juice collecting disc 6 and the side wall of the screw 5 is 1.9-2.1 mm, specifically, L4 = 2 mm; the distance A between the screw thread of the screw 5 and the side wall of the screw 5 is 0.8 mm; the protruding width B1 of the first grinding rib 41 is 0.5-0.7 mm, specifically... The protrusion width of the second grinding rib 61 is B2 = 0.75-0.95mm, specifically, B2 = 0.7mm or 0.8mm; the distance between the thread of the screw 5 and the first grinding rib 41 is C1 = 0-0.4mm, specifically, C1 = 0.2mm or 0.3mm; the distance between the thread of the screw 5 and the second grinding rib 61 is C2 = 0.15-0.55mm, specifically, C2 = 0.35mm or 0.4mm.

[0061] It should also be noted that this application does not specifically limit the relative height of the first grinding rib 41 and the second grinding rib 61. As a preferred embodiment of this application, such as... Figure 5 As shown, the height H1 of the first grinding rib 41 and the height H2 of the second grinding rib 61 satisfy: 0.63≤H1 / H2≤0.93.

[0062] By setting the relationship between H1 and H2 to 0.63 ≤ H1 / H2 ≤ 0.93, meaning the height of the first grinding rib is at least half the height of the second grinding rib, it is ensured that the height range of the first grinding rib 41 can fully grind materials with larger particle sizes. Simultaneously, it ensures that the lower limit ring can fully bear the grinding task within the height range of the second grinding rib 61. This reasonable vertical distribution of the grinding task extends the grinding path, ensuring effective fine grinding of the material and thorough juice extraction. This not only significantly improves the juice yield but also reduces the particle size of the material after fine grinding between the second grinding rib and the screw, making it less prone to clogging and preventing radial disturbance of the screw. Furthermore, to ensure the structural strength of the juicing mesh, the first grinding section H1 should not be too small; H1 / H2 should not be less than 0.63.

[0063] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
