[0005] The second technical problem to be solved by the utility model is to provide a kitchen waste disposer with the above-mentioned grinding structure.

[0006] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a grinding structure for a kitchen waste disposer, comprising:

[0007] A grinding cover, wherein a grinding chamber is provided inside the grinding chamber, a feed inlet is provided at the upper part of the grinding chamber, and a discharge outlet is provided at the lower part of the grinding chamber;

[0010] Features:

[0011] The outer circumferential surface of the first grinding disc and the inner circumferential surface of the grinding ring are spaced apart from each other to form a vertically extending annular cavity, and at least the upper portion of the annular cavity is a tapered section in which the flow area on the cross section gradually decreases from top to bottom. A first component is provided on the wall surface of the tapered section, and the first component is arranged to push the garbage in the annular cavity downward under the rotational force of the first grinding disc.

[0013] In order to form the above-mentioned tapered section, the outer circumference of the first grinding disc and the inner circumference of the grinding ring corresponding to the tapered section may be an inverted conical surface and a vertical surface, respectively.

[0016] In this way, by arranging the first convex strip on the conical surface of the first grinding disc, when the first grinding disc rotates, the kitchen waste can be driven to rotate. At the same time, the first convex strip can generate downward pressure to squeeze the kitchen waste downward and speed up the grinding speed.

[0017] Furthermore, it also includes:

[0018] The annular convex strip is arranged on the inverted cone surface of the grinding ring along the circumferential direction, and there are at least two annular convex strips, which are arranged at intervals along the up-down direction.

[0019] Under the action of the rotational force of the first grinding disk, some kitchen waste may splash upward along the cone surface. The above-mentioned annular convex strips can prevent the splashing from occurring and provide radial cutting and tearing forces during the grinding of the kitchen waste, thereby helping to improve the grinding speed and effect.

[0026] More preferably, the second protruding teeth arranged at intervals in the circumferential direction form a group, there are at least two groups, and are arranged at intervals on both sides of the first protruding teeth in the up-down direction.

[0027] Furthermore, the size of the equal-diameter section of the annular cavity in the up-down direction is greater than the size of the tapered section in the up-down direction.

[0028] To further improve the grinding effect, preferably, the inner circumferential surface of the grinding ring further comprises an end surface folded back and extending outward from the lower edge of the second vertical surface, and a third vertical surface extending downward from the outer edge of the end surface;

[0029] The grinding structure also includes:

[0031] In this way, the cooperation between the second grinding disc, the end surface and the third vertical surface can further grind the garbage passing through the equal diameter section.

[0032] Furthermore, the outer portion of the second grinding disc is provided with a plurality of vertically penetrating material holes at intervals along the circumferential direction, so that the ground garbage can be discharged from the material holes in a timely manner.

[0033] Furthermore, the upper surface of the second grinding disc also has a central portion located inside the outer portion, attached to the bottom surface of the first grinding disc, and the central portion is located above the outer portion and the two are connected by an annular step surface.

[0034] The design of the annular step surface can increase the volume above the outer portion of the second grinding disc, so that the food waste from the equal-diameter section can be filled in the space above the outer portion of the second grinding disc, thereby improving the grinding effect of the food waste. And it can prevent the food waste from flowing to the inner portion of the second grinding disc.

[0035] In the above schemes, preferably, a blade is further included, which is arranged at the upper end of the annular cavity and can rotate circumferentially relative to the grinding ring under the action of the driving mechanism. The blade can continuously move the kitchen waste during rotation to prevent the kitchen waste from getting stuck, and can also cut part of the kitchen waste.

[0036] Furthermore, there are at least two blades which are arranged at intervals along the circumferential direction.

[0037] Furthermore, the blades are arranged to be inclined downward from inside to outside.

[0038] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a kitchen waste disposer, characterized by having the grinding structure as described above.

The tapered surface 31 is spaced opposite to the inverted tapered surface 21 of the grinding ring 2 to form a tapered section 20a of the annular chamber 20. The flow area on the cross section of the tapered section 20a gradually decreases from top to bottom. In addition, a first component is provided on the tapered surface 31 of the first grinding disc 3, and the first component is arranged to push the garbage in the annular chamber 20 downward under the action of the rotational force of the first grinding disc 3. Specifically, the first component includes a plurality of first convex strips 32, which are arranged on the conical surface 31 of the first grinding disc 3 at intervals along the circumferential direction and extend in a posture of fitting the conical surface 31, and each second convex strip is inclined relative to the horizontal plane, and the inclination directions of two adjacent first convex strips 32 in the circumferential direction are opposite; and the first convex strips 32 arranged at intervals in the circumferential direction form a group, and there are at least two groups arranged at intervals along the vertical direction.

[0054] This embodiment utilizes the dead weight of the kitchen waste and designs three grinding layers to grind and crush the kitchen waste: the V-shaped grinding layer formed by the first tapered section initially reduces the particle size of the kitchen waste; the vertical channel layer formed by the second equal-diameter section further crushes the kitchen waste ground by the cutting and stirring direction; the third radial grinding layer uses the combination of the second grinding disc and the grinding ring to imitate the grinding effect of a stone mill. The combination of the three grinding layers can efficiently and quickly process the kitchen waste, and effectively improve the grinding fineness, prevent the user's drainage pipe from being blocked, and enhance the user experience.
