[0031] As Figures 1 - 4 shown, the present invention provides a grinding assembly, which can be used in a kitchen waste processor, can effectively cut hard-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 the kitchen waste processor from being blocked by garbage.

[0032] The grinding assembly includes a grinding ring 10 and a cutter head 20.

[0033] The grinding ring 10 can be fixed inside the housing of the kitchen waste processor. The grinding ring 10 is provided with more than one strip-shaped protrusion 11 extending along its inner wall surface. The grinding ring 10 can be a tubular structure with upper and lower openings as a whole, and the strip-shaped protrusion 11 can be formed by extending along the inner wall surface of the grinding ring 10. A plurality of strip-shaped protrusions 11 can be provided and arranged circumferentially along the inner wall surface of the grinding ring 10.

[0034] The cutter head 20 is disposed within the grinding ring 10 and is capable of rotating relative to the grinding ring 10. The cutter head 20 can be mounted on the motor shaft of the food waste processor, and the cutter head 20 is driven by the motor to rotate relative to the grinding ring 10. On the upper surface of the cutter head 20, there is provided one or more protrusions 21 extending in the axial direction of the cutter head. The protrusion 21 includes a first edge 211, the first edge 211 faces the inner wall of the grinding ring 10, and there is a gap between the first edge 211 and the strip-shaped protrusion 11. The protrusion 21 can be adjacent to the edge position of the cutter head 20, and its first edge 211 faces the inner wall of the grinding ring 10. Wherein, in the state where the cutter head 20 rotates relative to the grinding ring 10, the first edge 211 passes through the strip-shaped protrusion 11 and cooperates with the strip-shaped protrusion 11 to cut an object, that is, it is beneficial to cut the object through the gap between the first edge 211 on the protrusion 21 and the strip-shaped protrusion 11. Since the strip-shaped protrusion 11 can increase the grinding contact area and grinding time when cooperating with the first edge 211, the strip-shaped protrusion 11 can grind food residues for a long time. When the food residues enter the gap between the strip-shaped protrusion 11 and the first edge 211, they rotate along with the first edge and are ground on the strip-shaped protrusion until they break, which increases the hitting efficiency of the inner wall of the grinding ring, making the food residues hitting the wall surface easier to break.

[0035] On the inner wall of the grinding ring 10, a plurality of second water filtering holes 13 can also be provided to discharge the processed food residues.

[0036] In some embodiments, the above-mentioned strip-shaped protrusion 11 is arc-shaped and extends obliquely along the inner wall surface of the grinding ring 10 relative to the center line of the grinding ring 10. The arc-shaped strip-shaped protrusion 11 and its oblique extension along the inner wall surface of the grinding ring 10 further increase the grinding contact area and grinding time when cooperating with the first edge 211 on the protrusion 21.

[0037] Furthermore, the extending directions of the plurality of strip-shaped protrusions 11 can be the same, that is, they are all inclined in the clockwise direction or the counterclockwise direction.

[0038] In some embodiments, the protrusion 21 further includes a plurality of second edges 212, and the orientations of the second edges 212 are different from those of the first edge 211. During the rotation of the cutter head 20, the first edge 211 on the protrusion 21 cooperates with the strip-shaped protrusion 11 to cut and grind food, and at the same time, the plurality of second edges 212 of the protrusion 21 itself cut and break large food wastes, such as bone residues.

[0039] There can also be a plurality of protrusions 21, for example, two, and the two protrusions 21 are symmetrically arranged relative to the center of the cutter head 20.

[0040] In some embodiments, the bump 21 is in the shape of an isosceles triangle. The apex side of the isosceles triangle bump 21 forms a first edge 211, and the two base angle sides form a second edge 212. Among them, the perpendicular bisector of the isosceles triangle bump passes through the center of the cutter head 10. However, this is not limited thereto, and the bump 21 can also be other shapes including multiple edges.

[0041] In some embodiments, the grinding ring 10 is provided with a plurality of cutting teeth 12 extending along its radial inner side. The plurality of cutting teeth 12 are arranged along the circumferential direction of the grinding ring 10, and there are gaps between the plurality of cutting teeth. The shape of the cutting teeth 12 can be trapezoidal, fan-shaped, etc. The first edge 211 of the bump 21 protrudes beyond the peripheral edge of the cutter head 20 and is located above the cutting teeth 12; in a state where the cutter head 20 rotates relative to the grinding ring 10, the first edge 211 cooperates with the cutting teeth 12 to cut an object.

[0042] During the rotation of the cutter head 20, the first edge 211 of the bump 21 cooperates with the strip-shaped protrusion 11 to cut and grind food residues. The food residues enter the gap between the grinding ring 10 and the peripheral edge of the cutter head 20, and are further ground and cut thoroughly by the cooperation of the bottom surface of the first edge 211 and the cutting teeth 12.

[0043] In some embodiments, a breaker hammer 22 is further provided on the cutter head 20. The first end (the end close to the center of the cutter head 20) of the breaker hammer 22 is hinged to the cutter head 20. A notch 221 is provided on the upper surface of the second end (the end far from the center of the cutter head 20) of the breaker hammer 22. The notch 211 is located below the strip-shaped protrusion 11. The breaker hammer 22 can swing relative to the cutter head 20. In a state where the breaker hammer 22 swings relative to the cutter head 20, the notch 211 cooperates with the bottom of the strip-shaped protrusion 11 to cut an object.

[0044] Under the action of the centrifugal force of the rotation of the cutter head 20 and the impact force of food waste, the breaker hammer 22 swings with the first end as the axis to impact and break the food waste, and can also throw the food waste onto the inner wall of the grinding ring 10, where it can be cut and crushed by the strip-shaped protrusion 11; on the other hand, the swinging of the breaker hammer 22 makes the front notch 221 cooperate with the bottom of the strip-shaped protrusion 11 to further grind the food waste.

[0045] In some embodiments, the second end of the breaker hammer 22 protrudes beyond the peripheral edge of the cutter head 20 and is located above the cutting teeth 12 of the grinding ring 10; in a state where the cutter head 20 rotates relative to the grinding ring 10, the lower surface of the second end of the breaker hammer 22 cooperates with the cutting teeth to cut an object.

[0046] The breaker hammer 22 can not only impact and crush the food waste, but also cut and grind the food waste through the cooperation of the notch 211 on the upper surface of the second end of the breaker hammer 22 and the strip-shaped protrusion 11, and further cut and grind the food waste through the cooperation of the lower surface extending from the second end of the breaker hammer 22 and the cutting teeth 12, so that the breaker hammer 22 has crushing and multi-stage cutting and grinding effects.

[0047] Furthermore, a plurality of stepped ridges 222 are provided near the first end of the breaker hammer 22. The plurality of stepped ridges 222 are sharp structures, and when the breaker hammer 22 swings, the breaker hammer 22 impacts and crushes the food more fully.

[0048] In some embodiments, a plurality of first filter holes 22 are provided on the cutter disc 20, and the first filter holes 22 are located in the swinging area of ​​the breaker 22; a limiting convex portion is also provided on the cutter disc 20, and the limiting convex portion includes a first limiting convex portion 23 and a second limiting convex portion 24, and the first limiting convex portion 23 and the second limiting convex portion 24 are staggered in the radial direction of the cutter disc 20 to avoid the first filter hole, and the first limiting convex portion 23 and the second limiting convex portion 24 are respectively used to limit the swinging stroke of the breaker. The first filter hole 22 is located in the swinging area of ​​the breaker 22, so that the breaker 22 sweeps over the food residue entering the first filter hole 22 during the swinging process to be ground, and the ground food residue can be discharged through the first filter hole 22, and the first limiting convex portion 23 and the second limiting convex portion 24 are staggered in the radial direction of the cutter disc 20, which can provide an avoidance space for the first filter hole 22, and then more first filter holes 22 can be set in the swinging area of ​​the breaker 22, and the contact grinding area between the breaker 22 and the first filter hole 22 is increased.

[0049] In some embodiments, two crushing hammers 22 are provided, symmetrically arranged relative to the center of the cutter disc; two protrusions 21 are provided, symmetrically arranged relative to the center of the cutter disc 20, wherein the protrusions 21 and crushing hammers 22 are arranged alternately in the circumferential direction of the cutter disc 20. The alternately arranged crushing hammers 22 and protrusions 21 can form a multi-position grinding structure on the cutter disc 20, so that the food is ground more fully.

[0050] In some embodiments, a plurality of vertical knives 26 are further provided on the cutter disc 20 , and the plurality of vertical knives protrude from the lower surface of the cutter disc 20 , and / or a plurality of vertical knife protrusions 26 protrude from the upper surface of the cutter disc 20 .

[0051] The present invention also provides a food waste disposer, comprising: a grinding assembly as described in any of the above embodiments. Specifically, the food waste disposer further comprises: a housing and a motor disposed in the housing. The grinding assembly is disposed in the housing, and the grinding ring 10 is fixed to the housing; the driving shaft of the motor is connected to the cutter disc 20, and is used to drive the cutter disc 20 to rotate relative to the grinding ring 10.

[0052] Food waste enters the interior of the grinding chamber of the processor. The cutter head 20 rotates at high speed following the driving motor. The large pieces of food are impacted and broken by multiple second edges 212 of the bump 21 itself. The crushed food waste is thrown to the inner wall of the grinding ring 10. On the one hand, the food waste is further cut by the strip-shaped protrusions 11 on the inner wall of the grinding ring 10. On the other hand, the first edge 211 of the bump 21 sweeps across the strip-shaped protrusions 11 to further cut and tear the food residue, etc. The processed food residue enters the gap between the periphery of the cutter head 20 and the inner wall of the grinding ring 10, and further grinding is carried out through the cooperation of the bottom surface of the extended first edge 211 of the bump 21 and the cutting teeth 11 on the grinding ring 10. At the same time, the crushing hammer 22 swings due to the centrifugal force when the cutter head 20 rotates at high speed and the impact force of the food. During the swinging process, it also impacts with the limiting protrusion, forming a rotational contrast with the cutter head 20. During the swinging process of the crushing hammer 22, the food waste is impacted and broken. And during the swinging process, the bottom surface of the crushing hammer 22 cooperates with the first filter hole 25 to carry out grinding treatment on the food residue, and the notch 221 on the upper surface of the second end of the crushing hammer 22 cooperates with the bottom of the strip-shaped protrusions 11 to grind the crushed food waste, and the lower surface of the second end of the crushing hammer 22 also cooperates with the cutting teeth 11 on the grinding ring 10 for further grinding, so that the crushing hammer 22 has the effect of impacting and crushing the food waste and multiple grinding of the food waste.
