Detailed Embodiments

[0070] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0071] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "contacted", "communicated" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0072] The first aspect of the present invention provides a grinding assembly; as Figures 1 - 5 shown, the grinding assembly includes: a grinding ring assembly 10 and a cutter head assembly 20.

[0073] The cutter head assembly 20 includes M cutter heads arranged in sequence along the radial direction, where M≥1. In the radial direction of the cutter head, the first cutter head to the Mth cutter head can be distributed in sequence from the radial inner side to the radial outer side of the cutter head.

[0074] The grinding ring assembly 10 includes N grinding rings arranged in sequence along the radial direction; the first grinding ring is sleeved on the outer periphery of the first cutter head, the Nth grinding ring is sleeved on the outer periphery of the Mth cutter head, and the N grinding rings and the M cutter heads are arranged alternately in sequence along the radial direction to form a multi-stage grinding structure; M = N, and the cutter head assembly 20 can be controlled to rotate one or more cutter heads relative to the grinding ring assembly 10.

[0075] In some embodiments, a gap is formed between each adjacent cutter head and grinding ring. This gap can be the gap formed between the two in the radial direction, and / or the gap formed between the two in the axial direction. This gap can perform a cutting and / or grinding function on food residues.

[0076] For example, the first grinding ring is sleeved around the first cutter head, the second grinding ring is sleeved around the second cutter head, and the Mth grinding ring is sleeved around the Nth cutter head.

[0077] The grinding ring assembly 10 can be a fixed part, and the cutter head assembly can be a movable part. In one example, one of the cutter heads in the cutter head assembly can rotate relative to the grinding ring assembly 10. In another example, multiple cutter heads in the cutter head assembly can rotate relative to the grinding ring assembly 10. Further, multiple cutter heads (M cutter heads) can rotate relative to the grinding ring assembly 10 as a whole. For example, when the first cutter head is controlled to rotate, the second cutter head, the third cutter head, and the Mth cutter head rotate together, so that a relative rotation is generated between the first cutter head and the first grinding ring, and a first-stage grinding structure is formed by using the gap between the two. A relative rotation is generated between the second cutter head and the second grinding ring, and a second-stage grinding structure is formed by using the gap between the two.

[0078] Both the grinding ring assembly and the cutter head assembly adopt a split structure. Multiple grinding ring assemblies and cutter head assemblies form a transverse (radial) multi-stage grinding structure. By deriving from a single-stage grinding structure in the prior art to a multi-stage grinding structure, the number of grinding times of the cutter head and the grinding ring is increased in a variable direction, and the grinding effect is better. The processing capacity of residual food waste is effectively increased, the problem that flexible long fibers are difficult to process during the operation of the kitchen waste processor is solved, and the flexible long fibers are effectively cut.

[0079] In some embodiments, among the N grinding rings and M cutter heads, the adjacent ith grinding ring and the ith cutter head are arranged up and down, N≥i≥1, M≥i≥1. Alternatively, among the N grinding rings and M cutter heads, at least the Nth grinding ring and the Mth cutter head are arranged up and down.

[0080] The cutter head assembly 20 further includes at least one second connecting member 23 connected between the Eth cutter head and the (E + 1)th cutter head. The second connecting member 23 is arranged up and down with the Eth grinding ring, and the second connecting member 23 overlaps with part of the Eth grinding ring; when the cutter head rotates relative to the grinding ring assembly, the second connecting member and the Eth grinding ring cooperate to form a cutting and / or grinding effect, M - 1≥E≥1, N≥E - 1≥1.

[0081] For example, one or more second connecting members 23 are connected between the first cutter head 21 (which can also be called the inner disk 21) and the second cutter head (which can also be called the outer disk 22). Two second connecting members 23 can be connected, and the two second connecting members 23 are symmetrically arranged with respect to the center of the cutter head. The second connecting member 23 is arranged up and down with the first grinding ring 11 (which can also be called the inner ring 11), and the second connecting member 23 overlaps with part of the first grinding ring 11 up and down. Up and down is the axial direction of the cutter head, that is, along the direction of the central axis of the cutter head. When the first cutter head and the second cutter head rotate relative to the grinding ring assembly, the up and down gap between the second connecting member 23 and the first grinding ring forms a cutting and / or grinding effect.

[0082] In some embodiments, the grinding ring assembly further includes at least one first connecting member 13 connected between the F-th grinding ring and the (F + 1)-th grinding ring. The first connecting member 13 and the (F + 1)-th cutter head are arranged vertically, and the first connecting member 13 overlaps with a part of the (F + 1)-th cutter head. When the cutter head rotates relative to the grinding ring assembly, the (F + 1)-th cutter head and the first connecting member cooperate to form a cutting and / or grinding effect, where N - 1 ≥ F ≥ 1 and M - 1 ≥ F ≥ 1.

[0083] For example, the first grinding ring 11 (which can also be referred to as the inner ring 11) and the second grinding ring 12 (which can also be referred to as the outer ring 12) are connected by a first connecting member 13. The first connecting member 13 partially overlaps with a part of the second outer disc (which can also be referred to as the outer disc 22). When the cutter head rotates relative to the grinding ring assembly, the first connecting member 13 and the second outer disc cooperate to form a cutting and / or grinding effect.

[0084] In some embodiments, a plurality of cutting teeth are provided on the periphery of the N-th cutter head, and there are gaps between the plurality of cutting teeth. A plurality of cutting blades extending radially inward are formed on the inner peripheral wall of the M-th grinding ring, and the cutting blades and the cutting teeth are arranged vertically; when the cutter head rotates relative to the grinding ring assembly, the cutting teeth and the cutting blades cooperate to form a cutting and / or grinding effect.

[0085] For example, the cutter head assembly includes two cutter heads and two grinding rings. Among them, the first cutter head can be referred to as the inner disc 21, the second cutter head can be referred to as the outer disc 22, the first outer ring can be referred to as the inner ring 11, and the second outer ring can be referred to as the outer ring 12. A plurality of cutting teeth 27 are provided on the periphery of the outer disc, and there are gaps between the plurality of cutting teeth 27. A plurality of cutting blades 14 extending radially inward are formed on the inner peripheral wall of the outer ring 12, and the cutting blades 14 and the cutting teeth 27 are arranged vertically; when the cutter head rotates relative to the grinding ring assembly, the cutting teeth 27 and the cutting blades 14 cooperate to form a cutting and / or grinding effect.

[0086] In some embodiments, a breaker hammer is provided on the first cutter head. The connecting end of the breaker hammer is hinged to the cutter head, and the breaker hammer can swing relative to the cutter head about the hinge point. The first cutter head is also referred to as the inner disk 21. A breaker hammer 24 is provided on the inner disk 21. The connecting end of the breaker hammer 24 is hinged to the inner disk 21, and the breaker hammer 24 can swing relative to the inner disk 21. The first end of the breaker hammer 24 close to the center of the inner disk 21 is the connecting end, and the end far from the center is the second end, which is also the free end. When the inner disk 21 rotates, the breaker hammer 24 can swing relative to the inner disk 21 by centrifugal force, or the breaker hammer 24 can be rotated relative to the inner disk 21 by food impact. The rotation of the breaker hammer 24 relative to the inner disk 21 can impact and break the food. Since the second end of the breaker hammer 24 extends to the outer disk 22, the breaker hammer 24 cooperates with the outer disk 22 and the inner ring 11 to form a cutting and grinding structure, thereby forming a multi-stage cutting and grinding structure in the radial direction of the cutter head 20, and the food residue is processed more thoroughly.

[0087] In some embodiments, a notch is provided at the free end of the breaker hammer, where the free end is opposite to the connecting end; one or more protrusions are provided on the inner peripheral wall of the Nth grinding ring; in a state where the breaker hammer swings relative to the first cutter head, the notch sweeps across the protrusion to form a cutting and / or grinding effect.

[0088] A notch 241 is provided at the second end of the breaker hammer 24. The notch 241 can be arc-shaped. The Nth grinding ring can be referred to as the outer ring 12. The outer ring 12 is cylindrical, and one or more protrusions 15 are provided on the inner wall of the outer ring 12. For example, a plurality of protrusions 15 arranged circumferentially along the inner wall of the outer ring 12 can be provided. In a state where the breaker hammer 24 swings relative to the inner disk 21, the notch 241 cooperates with the protrusion 15 to cut an object, thereby forming a cutting and grinding structure. In one example, the protrusion 15 has a spike structure and is staggered with the tooth-shaped structure on the periphery of the outer disk 22 of the cutter head 20 to ensure that it will not be stuck due to the spike structure during assembly and cannot be installed. The protrusion 15 can pierce the food waste hammered by the breaker hammer 24, and at the same time cooperate with the notch 241 provided at the second end of the breaker hammer 24 to form a cutting and grinding structure.

[0089] In some embodiments, a plurality of convex ribs are respectively provided on both sides in the swinging direction of the breaker hammer, and the convex ribs extend from the top to the bottom of the breaker hammer. A plurality of impact convex ribs 242 are also provided at a position of the breaker hammer 24 close to the connecting end. The plurality of impact convex ribs 242 form a sharp structure to impact and crush the food waste. A limiting convex portion is provided on the first cutter head to limit the swinging stroke of the breaker hammer.

[0090] Such as Figures 1 - 5As shown, the second aspect of the present invention provides a grinding assembly, which can be used in a kitchen waste processor, and can effectively cut off difficult-to-clean garbage such as flexible long fibers, avoid problems such as aggregation or entanglement of garbage such as flexible long fibers, and effectively prevent garbage from clogging the kitchen waste processor.

[0091] The grinding assembly may include a grinding ring 10 and a cutter disc 20, and may also be referred to as a grinding ring assembly 10 and a cutter disc assembly 20.

[0092] The grinding ring 10 can be fixed in the housing of the kitchen waste processor. The grinding ring 10 includes an inner ring 11 and an outer ring 12, and the inner ring 11 and the outer ring 12 are connected by more than one first connecting member 13. The outer ring 12 can be in a cylindrical shape, and the inner ring 11 is located at the bottom position inside the outer ring 12 and is connected by two first connecting members 13 that are centrosymmetric with respect to the center of the inner ring 11, for example, welded together. The first connecting member 13 can be in a fan shape.

[0093] The cutter disc 20 is capable of rotating relative to the grinding ring 10. The center of the cutter disc 20 can coincide with the center of the grinding ring 10. The cutter disc 20 can be installed on the rotating shaft in the kitchen waste processor, and the cutter disc 20 is driven to rotate by a driving motor. The cutter disc 20 can be arranged inside the outer ring 12 of the grinding ring 10 and above the inner ring 11. Specifically, the cutter disc 20 includes an inner disc 21 and an outer disc 22, and the inner disc 21 and the outer disc 22 are connected by more than one second connecting member 23. For example, the inner disc 21 and the outer disc 22 can be connected together by two second connecting members 23 that are centrosymmetric with respect to the center of the inner disc 21, so that the inner disc 21 and the outer disc 22 rotate together when the cutter disc 20 rotates. The second connecting member 23 is located above the inner ring 11, and a cutting portion 27 is provided on the periphery of the outer disc 22. The cutting portion 27 is located above the first connecting member 13. In other words, in the axial direction of the cutter disc 20, the second connecting member 23 overlaps or partially overlaps with the inner ring 11, and the cutting portion 27 overlaps or partially overlaps with the first connecting member 13. So that in the state where the cutter disc 20 rotates relative to the grinding ring 10, the second connecting member 23 and the inner ring 11 cooperate to cut an object, thereby forming a first-stage cooperative cutting on the radially outer side, and the cutting portion 27 of the outer disc 22 and the first connecting member 13 cooperate to cut an object, thereby forming a second-stage cooperative cutting on the radially inner side.

[0094] The grinding ring 10 of the present invention connects the inner ring 11 and the outer ring 12 through the first connecting member 13. The cutter head 20 connects the inner disc 21 and the outer disc 22 through the second connecting member 23. When the cutter head 20 rotates relative to the grinding ring 10, the first connecting member 13 can cooperate with the cutting portion 27 on the outer disc 22 to form a primary cutting and grinding structure. The second connecting member 23 cooperates with the inner disc 21 to form a secondary cutting. Moreover, the primary cutting and grinding structure and the secondary cutting and grinding structure are distributed at different positions in the radial direction of the cutter head 20. Compared with the prior art where the multi-stage cutting and grinding structure is arranged in the axial direction of the cutter head 20, while ensuring the multi-stage cutting effect, the longitudinal space occupied by the food waste processor is reduced, and the assembly is more convenient.

[0095] Further, the above-mentioned outer disc 22 is located between the inner ring 11 and the outer ring 12, and the inner ring 11 is located between the outer disc 22 and the inner disc 21. There is a gap between the peripheral edge of the outer disc 22 and the outer ring 12, and there is a gap between the inner disc 21 and the inner ring 11 so that the objects to be cut and ground (such as food residues) can flow out from the gaps.

[0096] In some embodiments, the cutting portion 27 on the peripheral edge of the outer disc 22 includes a plurality of cutting teeth distributed along the peripheral edge of the outer disc; the outer ring 12 is provided with a plurality of cutting blades 14 extending towards its radial inner side. The cutting blades 14 can extend towards the radial inner side along the bottom edge of the outer ring 12 and are evenly distributed along the circumferential direction of the outer ring 12. In the state where the cutter head 20 rotates relative to the grinding ring 10, the cutting teeth cooperate with the first connecting member 13 and the cutting blades 14 to cut the object, that is, while the cutting teeth cooperate with the first connecting member 13 to cut and grind the object, they can also cooperate with the cutting blades 14 to cut and grind the object, improving the efficiency of grinding and crushing food.

[0097] Further, at least one side surface of the first connecting member 13 has a first cutting edge, and the included angle formed by the surface of the first cutting edge and the lower surface of the outer disc 22 is an acute angle; and / or, at least one side surface of the second connecting member 23 has a second cutting edge, and the included angle formed by the surface of the second cutting edge and the upper surface of the inner ring 11 is an acute angle. The cutting edge with an acute angle cuts the object more sharply, improving the cutting and grinding efficiency.

[0098] In some embodiments, a vertical knife 26 and a hole corresponding to the vertical knife 26 are provided on the second connecting member. When the cutter head 20 rotates, the second connecting member 23 cooperates with the inner disc 21 to form a secondary cutting and grinding structure, and the vertical knife 26 pierces the food. Among them, the hole corresponding to the vertical knife 26 on the second connecting member 23 and the inner disc 21 cooperate to form a cutting and grinding structure, that is, while piercing the food with the vertical knife 26, it can also cooperate with the inner disc 21 through the hole corresponding to the vertical knife 26 to cut and grind the food, further improving the processing ability of food residues with flexible long fibers and high toughness (such as corn leaves, fruit peels, vegetable leaves, etc.). The vertical knife 26 can be a triangular vertical knife, which is obliquely arranged upward from the surface of the inner disc 21.

[0099] In some embodiments, a breaker 24 is provided on the inner disk 21. The connecting end of the breaker 24 is hinged to the inner disk 21, and the second end of the breaker 24 extends to the outer disk 22. The breaker 24 can swing relative to the inner disk 21. One end of the breaker 24 close to the center of the inner disk 21 is the connecting end, and the end far from the center is the second end, which is also the free end. When the inner disk 21 rotates, the breaker 24 can swing relative to the inner disk 21 by centrifugal force, or the breaker 24 can be rotated relative to the inner disk 21 by food impact. The rotation of the breaker 24 relative to the inner disk 21 can impact and break the food. Since the second end of the breaker 24 extends to the outer disk 22, the breaker 24, the outer disk 22 and the inner ring 11 cooperate to form a third-stage cutting and grinding structure, and the positions of the breaker 24, the outer disk 22 and the inner ring 11 in the radial direction of the cutter disk 20 are different from those of the first-stage cutting and grinding structure and the second-stage cutting and grinding structure mentioned above, so that a multi-stage cutting and grinding structure is formed in the radial direction of the cutter disk 20, and the food residue is processed more thoroughly.

[0100] In some embodiments, a notch 241 is provided at the second end of the breaker 24. The notch 241 can be arc-shaped. The outer ring 12 is cylindrical, and more than one convex block 15 is provided on the inner wall of the outer ring 12. For example, a plurality of convex blocks 15 arranged circumferentially along the inner wall of the outer ring 12 can be provided. When the breaker 24 swings relative to the inner disk 21, the notch 241 and the convex block 15 cooperate to cut the object, thus forming a fourth-stage cutting and grinding structure. In one example, the convex block 15 has a spike structure and is staggered with the tooth-shaped structure on the periphery of the outer disk 22 of the cutter disk 20 to ensure that it will not be stuck due to the spike structure during assembly. The convex block 15 can pierce the food waste hammered by the breaker 24, and at the same time cooperate with the notch 241 provided at the second end of the breaker 24 to form a cutting and grinding structure.

[0101] Further, a plurality of convex ribs are respectively provided on both sides in the swinging direction of the breaker. The convex ribs extend from the top to the bottom of the breaker. A plurality of impact convex ribs 242 are also provided at a position of the breaker 24 close to the connecting end. The plurality of impact convex ribs 242 form a sharp structure to impact and crush the food waste.

[0102] In some embodiments, a limiting convex portion 25 is provided on the inner disk 21 to limit the swinging stroke of the breaker 24. Two limiting convex portions 25 can be provided and are close to the center position of the inner disk 21 to ensure that the swinging stroke of the breaker 24 is large and the swinging stroke is limited.

[0103] Two of the second connecting members 23 can be provided and are symmetrically arranged with respect to the center of the inner disk 21; two breakers 24 are provided and are symmetrically arranged with respect to the center of the inner disk 21. Among them, in the circumferential direction of the inner disk 21, the second connecting member 23 and the breaker 24 are alternately arranged.

[0104] The present invention also provides a food waste processor, including: the grinding assembly as described in any of the above embodiments. Specifically, the food waste processor further includes: a housing, the grinding ring 10 is fixed inside the housing; the cutter head 20 is arranged inside the outer ring 12 of the grinding ring 10 and above the inner ring 11; a driving motor is arranged inside the housing, and the driving shaft of the driving motor is connected to the inner disc 21 of the cutter head 20 to drive the cutter head 21 to rotate relative to the grinding ring.

[0105] During installation, first place the inner disc 21 and the outer disc 22 on the tooling, take the fan-shaped connecting structure with the vertical cutter and fixedly weld it between the inner disc 21 and the outer disc 22 to fix the inner and outer discs. Then install the breaker hammer, align the breaker hammer installation hole with the reserved installation hole of the inner disc 21, and after they are properly fitted, take the screw post to fix it. After installing the cutter head, first install the grinding ring into the food waste processor, then install the cutter head on the transmission shaft, take the nut to fix it, and then install the remaining components normally.

[0106] When the cutter head 20 rotates at a high speed, due to the action of the fan-shaped connecting device (the second connecting piece 23), the inner disc 21 and the outer disc 22 can rotate simultaneously. An inner ring 11 is arranged between the inner disc 21 and the outer disc 22, and the inner ring 11 is connected and fixed to the outer ring 12 without moving. The inner and outer rings and the inner and outer discs form relative motion, and the food residues are continuously ground and cut between the inner and outer rings and the inner and outer discs. At the same time, during the free swing of the breaker hammer, it continuously sweeps across the inner ring 11 and the inner and outer discs, hitting and breaking the food residues, and finally the finer food residues are discharged from the grinding chamber.

[0107] The grinding ring 10 is a fixed part, and the cutter head 20 is a movable part. The cutter head 20 rotates relative to the grinding ring 10 at a high speed, and the breaker hammer 24 swings by centrifugal force to impact and crush the food. At the same time, the food that is knocked flying can be further crushed by the convex blocks 15 on the inner wall of the outer ring 12. At the same time, the high-speed rotating cutter head 20 drives the vertical cutter 26 to pierce the food waste, and the food waste can also be crushed and ground by the cooperation of the holes corresponding to the vertical cutter 26 on the inner disc 21 and the inner ring 11. At the same time, the second connecting piece 23 cooperates with the inner ring 11 to further cut and grind the food waste. Further, the food residues flow into the gap between the outer disc 22 and the outer ring 12, and are further cut and ground by the cooperation of the cutting teeth 27 on the periphery of the outer disc 22, the first connecting piece 13, and the cutting piece 14, and the food such as flexible fibers that is difficult to process is completely crushed.
