Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, specifically to a high-efficiency meat grinder accessory and kitchen appliance. Background Technology

[0002] Currently, in order to produce fine, palatable meat particles without affecting meat output, and to prevent the meat from becoming mushy or from being too hot to affect its quality, many meat grinder manufacturers use double blades and double mesh, which means using two grinding blades and two meat discharge plates.

[0003] Chinese patent application No. 201820785008.7 discloses a double-sided meat grinder, including a mounting hole and a blade disc. The mounting hole is located at the center of the blade disc, and the blade disc is provided with at least two blades. The blades are distributed at 360-degree equal intervals, and each blade has a cutting edge, including a first cutting edge and a second cutting edge. There is a gap between the first cutting edge and the second cutting edge. The first cutting edge and the second cutting edge are vertically distributed and not on the same plane. The double-sided meat grinder is integrally formed, and the first cutting edge and the second cutting edge face the same direction. However, this patent also has the following drawbacks: the two sets of blades cut in the same direction, and the meat can only pass through in one direction, which easily leads to accumulation between the blade disc and the mesh plate, causing jamming and blockage. The efficiency is significantly reduced during commercial mass processing.

[0004] The patent also discloses a meat grinder, including a meat grinder sleeve, a pusher, a blade shaft, a single-sided meat grinder blade, a coarse-mesh mesh, and a fine-mesh mesh. The meat grinder also includes a double-sided meat grinder blade, which includes a mounting hole and a blade disc. The mounting hole is located at the center of the blade disc, and the blade disc is provided with at least two blades. The blades are distributed at 360-degree equal intervals and have cutting edges. The cutting edges include a first cutting edge and a second cutting edge, with a gap between the first cutting edge and the second cutting edge. The first cutting edge and the second cutting edge are vertically distributed and not on the same plane. The double-sided meat grinder blade is integrally formed. The double-sided meat grinder blade, the fine-mesh mesh, the single-sided meat grinder blade, and the coarse-mesh mesh are sleeved on the blade shaft, and the blade shaft is fixedly installed on the pusher. The pusher is connected to a drive mechanism to drive the double-sided meat grinder blade and the single-sided meat grinder blade to rotate. However, the patent also has the following drawbacks: the material pushed by the pusher is directly cut by the double-sided meat grinder, but for some harder and more difficult materials, it will increase the wear and jamming risk of the double-sided meat grinder, and will also cause the coarse mesh to be blocked or damaged, which will also easily affect the normal operation of the meat grinder. Summary of the Invention

[0005] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this application is to provide a high-efficiency meat grinder accessory and kitchen appliance.

The orientation of the first cutting edge is the same as the rotation direction of the double-sided meat grinder, and the orientation of the second cutting edge is the same as and opposite to the rotation direction of the double-sided meat grinder.

[0007] Furthermore, the cutting blade twists in a spiral shape from right to left along the rotation direction of the double-sided meat grinder.

[0008] Furthermore, the meat grinder disc includes a disc body, a second fixing hole opened at the center of the disc body, and a number of triangular-shaped blade holes arranged in a ring around the second fixing hole. The left and right sides of the inner edge of the blade holes are beveled to form a third blade.

[0009] Furthermore, each of the inner hole plate, middle hole plate, and outer hole plate has a mounting hole at its center, and several cutting holes are evenly distributed around the mounting hole. The cross-sectional area of ​​the cutting holes in the inner hole plate, middle hole plate, and outer hole plate decreases from right to left.

[0010] Furthermore, the cutting holes of the inner perforated plate are trapezoidal in shape, and a number of cutting holes are arranged in a ring array around the mounting holes of the inner perforated plate; the cutting holes of the middle perforated plate and the outer perforated plate are both circular, and the ratio of the diameter of the cutting holes of the middle perforated plate to the outer perforated plate is 1.2-2.0:1.

[0011] Furthermore, the high-efficiency meat grinder accessory also includes an extension tube fixed to the left end of the meat grinder cylinder and a meat grinder cover detachably installed on the left end of the extension tube. The meat grinder cover has a through hole in the middle and an annular sidewall extending to the right along the edge of the through hole. The outer sidewall of the annular sidewall protrudes outward with at least two locking blocks. The inner sidewall of the left end of the extension tube has an L-shaped slot corresponding to the position of each locking block. Each locking block rotates and locks into the corresponding L-shaped slot.

[0012] Furthermore, at least one limiting block is axially fixed to the outer sidewalls of the inner hole plate, middle hole plate, and outer hole plate. A first limiting groove is axially opened on the inner sidewall of the left end of the meat grinder cylinder, and the limiting block of the inner hole plate is embedded in the first limiting groove. A second limiting groove is axially opened on the inner sidewall of the extension cylinder, and the limiting blocks of the middle hole plate and outer hole plate are embedded in the second limiting groove. A limiting part is provided on the outer sidewall of the blade shaft. A positioning part that cooperates with the limiting part is provided in the first fixing hole of the double-sided meat grinder and the second fixing hole of the meat grinder disc.

[0013] Furthermore, the bottom of the tray has a feeding port and an annular connecting part extending downward along the edge of the feeding port. A first connecting cylinder is sleeved on the top outer wall of the feeding cylinder, and a second connecting cylinder is sleeved on the bottom of the annular connecting part. The first connecting cylinder and the second connecting cylinder are detachably connected. A lever is laterally hinged at the connection between the first connecting cylinder and the second connecting cylinder. One end of the lever extends out of the first connecting cylinder and the second connecting cylinder, and the other end of the lever extends into the feeding channel.

[0014] Furthermore, the high-efficiency meat grinder accessory also includes a pressing rod, which comprises a handle, a retaining ring, and a pressing part fixed from top to bottom. The outer diameter of the handle is smaller than the outer diameter of the pressing part, and the outer diameter of the retaining ring is larger than the outer diameter of the pressing part.

[0015] Another objective of this application is achieved through the following technical solution: a kitchen appliance, which includes the high-efficiency meat grinder accessory described above.

[0016] The beneficial effects of this application are as follows: The high-efficiency meat grinder accessory of this application adopts a double-sided meat grinder blade. The double-sided meat grinder blade is provided with a first blade and a second blade on the left and right sides of the cutting blade, respectively. The first blade faces the same direction as the rotation direction of the double-sided meat grinder blade, and the second blade faces the same direction but opposite to the rotation direction of the double-sided meat grinder blade. Under unidirectional rotation, complementary shearing forces can be formed, which can cut the meat tendons and fascia more thoroughly, making the minced meat less likely to become pasty and resulting in a more delicate texture. At the same time, the reverse cutting forces can cancel each other out, resulting in a more balanced overall force, more stable operation, and lower noise. It also reduces the risk of blade chipping and curling, and significantly improves durability. It can also effectively guide the flow of meat materials, avoid the accumulation and jamming caused by unidirectional pushing, and greatly improve the efficiency of continuous processing.

[0017] The high-efficiency meat grinder accessory of this application reduces the load on the double-sided meat grinder by adding an inner hole plate in front of the double-sided meat grinder, thereby improving cutting efficiency and uniformity.

[0018] The kitchen appliance of this application, by adopting the above-mentioned high-efficiency meat grinding accessories, can improve the meat grinding efficiency, and the ground meat is not pasty and has a delicate texture. Attached Figure Description

Detailed Implementation

[0037] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-17 Further explanation of this application is provided, but the content mentioned in the embodiments is not intended to limit this application.

[0038] See Figure 1-9 and Figure 17A high-efficiency meat grinder accessory includes a horizontally arranged grinding cylinder 1, a feeding cylinder 2 vertically fixed to the top of the grinding cylinder 1, and a tray 3 fixed to the top of the feeding cylinder 2. The grinding cylinder 1 forms a processing chamber 10, and the feeding cylinder 2 has a feeding channel 20 leading to the processing chamber 10. A meat grinder assembly 4 is installed in the processing chamber 10. The meat grinder assembly 4 includes a blade shaft 40, a spiral propeller 41 coaxially fixed to the right end of the blade shaft 40, and, from right to left, an inner perforated plate 42, a double-sided meat grinder blade 43, a middle perforated plate 44, a meat grinder disc 45, and an outer perforated plate 46 sequentially mounted on the blade shaft 40. The inner perforated plate 42 and the middle perforated plate 44... Both the outer perforated plate 46 and the screw propeller 41 are fixed inside the processing chamber 10. The screw propeller 41 drives the double-sided meat grinder 43 and the meat grinder disc 45 to rotate via a connecting drive mechanism. The double-sided meat grinder 43 includes a blade holder 431, a first fixing hole 432 axially opened at the center of the blade holder 431, and at least two cutting blades 433 arranged in a ring array fixed to the outer side wall of the blade holder 431. The left and right sides of the cutting blades 433 are respectively provided with a first cutting edge 434 and a second cutting edge 435. The orientation of the first cutting edge 434 is the same as the rotation direction of the double-sided meat grinder 43, and the orientation of the second cutting edge 435 is the same as and opposite to the rotation direction of the double-sided meat grinder 43. Specifically, the meat grinder cylinder 1 and the feeding cylinder 2 are integrally formed.

[0039] The high-efficiency meat grinder accessory of this application adopts a double-sided meat grinder blade 43. The double-sided meat grinder blade 43 has a first blade 434 and a second blade 435 on the left and right sides of the cutting blade 433, respectively. The first blade 434 faces the same direction as the rotation direction of the double-sided meat grinder blade 43, while the second blade 435 faces the same direction but opposite to the rotation direction of the double-sided meat grinder blade 43. Under unidirectional rotation, complementary shearing forces can be formed, which can cut the meat tendons and fascia more thoroughly, making the minced meat less likely to become pasty and resulting in a more delicate texture. At the same time, the reverse cutting forces can cancel each other out, resulting in a more balanced overall force, more stable operation, and lower noise. It also reduces the risk of blade chipping and curling, significantly improving durability. It can also effectively guide the flow of meat, avoiding the accumulation and jamming caused by unidirectional pushing, and greatly improving continuous processing efficiency.

[0040] The high-efficiency meat grinder accessory of this application reduces the load on the double-sided meat grinder 43 and improves cutting efficiency and uniformity by adding an inner hole plate 42 before the double-sided meat grinder 43.

[0041] In this embodiment, as Figure 8As shown, the cutting blade 433 twists in a spiral shape from right to left along the rotation direction of the double-sided meat grinder 43. The spiral twist enables progressive cutting, effectively reducing cutting resistance, lessening equipment load, and reducing energy consumption; the spiral structure has a guiding effect, guiding the meat material to be transported in an orderly manner, greatly reducing accumulation and jamming problems; the blade is subjected to force evenly and dispersedly, resulting in lower operating vibration and noise, while avoiding excessive instantaneous pressure on the blade edge, reducing wear, and extending service life; the progressive shearing method also improves the cutting effect of meat tendons, making the minced meat more uniform.

[0042] In this embodiment, as Figure 9 As shown, the meat grinder disc 45 includes a disc body 451, a second fixing hole 452 opened at the center of the disc body 451, and a plurality of triangular-shaped cutting holes 453 arranged in a ring around the second fixing hole 452. The left and right sides of the inner edge of the cutting holes 453 are chamfered to form a third cutting edge 454. The meat grinder disc 45 uses a ring array of cutting holes 453, which eliminates cutting dead angles in the entire circumference. During rotation, centrifugal force and cutting force are evenly distributed, significantly reducing the vibration and noise of the whole machine. At the same time, the triangular cutting edge has a larger cutting coverage area at the same speed, making feeding smoother and reducing the probability of material jamming.

[0043] In this embodiment, as Figure 7 As shown, the inner perforated plate 42, the middle perforated plate 44, and the outer perforated plate 46 all have mounting holes 421 at their centers. Several cutting holes 422 are evenly distributed around the mounting holes 421. The cross-sectional area of ​​the cutting holes 422 in the inner perforated plate 42, the middle perforated plate 44, and the outer perforated plate 46 decreases sequentially from right to left. The inner perforated plate 42 can pre-cut large pieces of meat, then the double-sided meat grinder 43 further cuts the meat into smaller pieces, which are then fed into the middle perforated plate 44 and compressed to a set size. The meat grinder disc 45 then further cuts the compressed meat into smaller pieces, which are then fed into the outer perforated plate 46, further compressed to a set size, and discharged through the cutting holes 422 of the outer perforated plate 46.

[0044] In this embodiment, as Figure 7 As shown, the cutting holes 422 of the inner perforated plate 42 are trapezoidal in shape, and a plurality of cutting holes 422 are arranged in a ring around the mounting holes 421 of the inner perforated plate 42. The inner perforated plate 42 serves a pre-cutting function, which can reduce the load on the double-sided meat grinder 43 and improve cutting efficiency and uniformity. In other embodiments, the cutting holes 422 of the inner perforated plate 42 may also be circular, with a diameter greater than or equal to that of the cutting holes 422 of the middle perforated plate 44.

[0045] The cutting holes 422 of both the central perforated plate 44 and the outer perforated plate 46 are circular, and the diameter ratio of the cutting holes 422 of the central perforated plate 44 to the outer perforated plate 46 is 1.2-2.0:1. The central perforated plate 44 can compress the meat into a set size, and then the meat enters the outer perforated plate 46 through the meat grinder disc 45, where it is further compressed and reduced to the set size. Optionally, the diameter ratio of the cutting holes 422 of the central perforated plate 44 to the outer perforated plate 46 can be 4:3, 5:3, or 6:3.

[0046] In this embodiment, as Figure 4 As shown, the high-efficiency meat grinder accessory also includes an extension tube 11 fixed to the left end of the meat grinder cylinder 1 and a meat grinder cover 12 detachably installed on the left end of the extension tube 11. The meat grinder cover 12 has a through hole 121 in its center and an annular sidewall portion 122 extending to the right along the edge of the through hole 121. At least two locking blocks 123 protrude outward from the outer sidewall of the annular sidewall portion 122. An L-shaped groove 111 is provided on the inner sidewall of the left end of the extension tube 11 corresponding to the position of each locking block 123. Each locking block 123 can be rotated into the corresponding L-shaped groove 111. The meat grinder accessory of this application, by detachably installing the meat grinder cover 12 on the left end of the extension tube 11 and using a rotational locking method, offers faster assembly and disassembly time, simpler structure, and easier use compared to existing threaded connections.

[0047] In this embodiment, as Figure 4 and Figure 7 As shown, at least one limiting block 423 is axially fixed to the outer sidewalls of the inner perforated plate 42, the middle perforated plate 44, and the outer perforated plate 46. A first limiting groove 101 is axially formed on the inner sidewall of the left end of the meat grinder 1, and the limiting block 423 of the inner perforated plate 42 is embedded in the first limiting groove 101. A second limiting groove 112 is axially formed on the inner sidewall of the extension cylinder 11, and the limiting blocks 423 of the middle perforated plate 44 and the outer perforated plate 46 are embedded in the second limiting groove 112. The limiting block 423 of the inner perforated plate 42 cooperates with the first limiting groove 101 on the meat grinder 1 to limit the rotation of the inner perforated plate 42; the limiting blocks 423 of the middle perforated plate 44 and the outer perforated plate 46 cooperate with the second limiting groove 112 on the extension cylinder 11 to restrict the rotation of the middle perforated plate 44 and the outer perforated plate 46.

[0048] like Figure 6 and Figure 8-9As shown, a limiting part 401 is provided on the outer wall of the blade shaft 40. Positioning parts 436 that cooperate with the limiting part 401 are provided in the first fixing hole 432 of the double-sided meat grinder 43 and the second fixing hole 452 of the meat grinder disc 45. The cross-section of the limiting part 401 is racetrack-shaped, and the corresponding first fixing hole 432 and second fixing hole 452 are also racetrack-shaped. This allows the double-sided meat grinder 43 and the meat grinder disc 45 to be fitted and fixed onto the blade shaft 40, so that the double-sided meat grinder 43 and the meat grinder disc 45 rotate together with the blade shaft 40. The blade shaft 40 can rotate within the mounting holes 421 of the inner hole plate 42, the middle hole plate 44, and the outer hole plate 46, while the inner hole plate 42, the middle hole plate 44, and the outer hole plate 46 do not rotate with the blade shaft. In other embodiments, the cross-sectional shape of the limiting part 401 can also be polygonal, elliptical, etc.

[0049] like Figure 6 As shown, the left end of the spiral propeller 41 has an axially formed threaded groove 411. The right end of the cutter shaft 40 is fixed with a stop 402 and a threaded portion 403 from left to right. The threaded portion 403 is screwed into the threaded groove 411, and the right side of the stop 402 abuts against the outside of the threaded groove 411. This structure facilitates the installation of the cutter shaft 40. In other embodiments, the cutter shaft 40 can also be integrally formed with the spiral propeller 41, or installed and fixed by means of insertion, interference fit, etc. In this embodiment, the outer diameter of the spiral propeller 41 gradually increases from right to left, and the thread pitch of the spiral propeller 41 gradually decreases from right to left. A connector 412 is fixed to the right end of the spiral propeller 41. The connector 412 is a regular polygon, such as a square. A baffle 413 is sleeved on the outer wall between the middle and right end of the spiral propeller 41 to prevent meat from entering the right end connection of the spiral propeller 41.

[0050] like Figure 4 and Figure 10 As shown, the outer side wall of the left end of the meat grinder 1 has an external thread 102, and the inner side wall of the right end of the extension cylinder 11 has an internal thread 113. The meat grinder 1 and the extension cylinder 11 are connected by the internal thread 113 and the external thread 102. This structure facilitates the assembly and disassembly of the meat grinder 1 and the extension cylinder 11. The extension cylinder 11 is detachably installed at the left end of the meat grinder 1 via a thread, and most of the meat grinding assembly 4 is located inside the extension cylinder 11. The meat grinding assembly 4 can be removed for cleaning by removing the extension cylinder 11. In other embodiments, the extension cylinder 11 and the meat grinder 1 can also be integrally formed.

[0051] like Figure 4 As shown, a plurality of handle portions 124 are fixed in a circular array on the outer side wall of the meat grinder cover 12. The handle portions 124 facilitate the assembly and disassembly of the meat grinder cover 12. Figure 10 As shown, a push rod 114 protrudes outward from the outer side wall of the extension tube 11. The push rod 114 facilitates the assembly and disassembly of the extension tube 113.

[0052] like Figure 4 As shown, a mounting cylinder 13 is fixed to the right end of the meat grinder 1, and the outer diameter of the mounting cylinder 13 is smaller than the outer diameter of the meat grinder 1. Specifically, the mounting cylinder 13 is integrally formed with the meat grinder 1, and its design facilitates connection with the connector of a kitchen appliance. A locking hole 131 is radially formed on the side wall of the mounting cylinder 13. The locking hole 131 facilitates locking with the connector of the kitchen appliance. A positioning notch 132 is formed on the side wall of the right end of the mounting cylinder 13. The positioning notch 132 facilitates docking with the connector of the kitchen appliance.

[0053] In this embodiment, as Figure 3 As shown, the bottom of the tray 3 is provided with a feeding port 30 and an annular connecting part 31 extends downward along the edge of the feeding port 30. The top outer wall of the feeding cylinder 2 is fitted with a first connecting cylinder 21, and the bottom of the annular connecting part 31 is fitted with a second connecting cylinder 32. The first connecting cylinder 21 and the second connecting cylinder 32 are detachably connected. A lever 22 is horizontally hinged at the connection between the first connecting cylinder 21 and the second connecting cylinder 32. One end of the lever 22 extends out of the first connecting cylinder 21 and the second connecting cylinder 32, and the other end of the lever 22 extends into the feeding channel 20. The meat grinder accessory of this application has a first connecting cylinder 21 sleeved on the top outer wall of the feeding cylinder 2 and a second connecting cylinder 32 sleeved on the bottom of the tray 3. A lever 22 is laterally hinged at the connection between the first connecting cylinder 21 and the second connecting cylinder 32. One end of the lever 22 extends out of the first connecting cylinder 21 and the second connecting cylinder 32, and the other end of the lever 22 extends into the feeding channel 20. The lever 22 is normally located in the middle of the feeding channel 20, forming a physical barrier to prevent the user's fingers from accidentally touching the internal rotating blades, thus meeting safety regulations. If the meat needs to be pushed during grinding, the user can manually push the lever 22 to temporarily release the obstruction and use the pressing rod 5 to assist in feeding. When the pressing rod 5 is not needed, the lever 22 can be manually pushed back to its original position.

[0054] like Figure 3 As shown, the outer side wall of the top of the feed cylinder 2 has an outwardly protruding annular enlarged portion 23, and the bottom of the annular enlarged portion 23 and the outer side wall of the feed cylinder 2 form an arc transition. This structure facilitates the installation of the tray 3. In other embodiments, the annular enlarged portion 23 may be omitted.

[0055] like Figure 3 As shown, the first connecting cylinder 21 has a first annular side groove 211 that mates with the outer wall of the annular enlarged portion 23, and the annular enlarged portion 23 is embedded in the first annular side groove 211. The above structure facilitates the assembly of the first connecting cylinder 21.

[0056] like Figure 2As shown, an annular sleeve 33 is fitted and fixed to the outer wall of the annular connecting part 31. A second annular groove 321 is formed inside the second connecting cylinder 32 to mate with the outer wall of the annular sleeve 33. The lower middle part of the annular sleeve 33 is inserted into the second annular groove 321. The above structure facilitates the assembly of the second connecting cylinder 32. In other embodiments, the annular sleeve 33 may not be fitted and fixed to the outer wall of the annular connecting part 31; instead, the lower middle part of the annular connecting part 31 may be inserted into the second annular groove 321.

[0057] like Figure 3 As shown, a first connecting seat 34 is fixed to the top outer edge of the first connecting cylinder 21, and a second connecting seat 34 is fixed to the bottom outer edge of the second connecting cylinder 32. The first connecting seat 34 and the second connecting seat 34 are fixed together by multiple screws. The above structure facilitates the fixing of the first connecting seat 34 and the second connecting seat 34.

[0058] like Figure 3 As shown, the top of the first connecting seat 34 has an upwardly protruding hinge post 241, and the lever 22 has a vertically opening hinge hole 221, which is sleeved on the hinge post 241. This structure facilitates the movement of the lever 22.
