Description

Technical Field

[0001] The utility model relates to the technical field of food waste treatment, and in particular to a grinding structure for a food waste disposer and a food waste disposer. Background Art

[0002] A food waste disposer usually refers to a grinding device that is installed under the kitchen sink and connected to the drain pipe to grind and crush food waste. The main grinding structure includes a grinding ring and a grinding disc arranged in the grinding ring. The grinding principle is as follows: the rotation of the grinding disc crushes and grinds the food waste, and the rotation of the grinding disc causes the food waste to generate centrifugal force, which causes the food waste to rub against the grinding ring to achieve the effect of re-grinding. After that, the food waste is ground into particles and discharged from the gap between the grinding disc and the grinding ring.

[0003] For example, the Chinese utility model patent with patent number CN202120257302.2 (publication number CN214460896U) discloses a grinding structure for a food waste disposer, which includes a shell, wherein the shell includes a grinding chamber with a feed opening at the top, wherein a grinding disc, a grinding ring fixedly arranged on the inner wall of the shell and a filter disc are arranged in the grinding chamber, wherein the grinding disc is arranged in the grinding ring, and a grinding gap is arranged between the grinding disc and the grinding ring, and the filter disc is located below the grinding disc, and a discharge opening is arranged on the side of the shell, wherein at least one grinding knife block is arranged on the top surface of the grinding disc, and at least one grinding sheet is arranged on the bottom surface of the grinding disc, and when the grinding disc rotates, the grinding knife block cooperates with the grinding ring to perform primary grinding of food waste, and the grinding sheet cooperates with the filter disc to perform secondary grinding of food waste.

[0004] However, most of the existing grinding structures are as shown in the above-mentioned patent, in which the grinding ring is a vertical structure, that is, the inner wall surface of the grinding ring is a vertical surface, and the wall surface of the grinding ring corresponding to the grinding blade block is also a vertical surface. In this way, the grinding area formed between the grinding ring and the grinding blade block is small, and the grinding efficiency needs to be further improved; in addition, during the rotation of the grinding disc, garbage is easily splashed upward and splashed out from the feed port, and a splash-proof cover is also required at the feed port, which is more troublesome. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a grinding structure for a kitchen waste disposer which can reduce garbage splashing upwards in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a kitchen waste disposer using the above-mentioned grinding structure in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the first technical problem mentioned above is: a grinding structure for a food waste disposer, comprising a grinding disc and a grinding ring surrounding the outer circumference of the grinding disc, wherein there is a gap between the outer circumference of the grinding disc and the inner wall surface of the grinding ring, and relative rotation can be generated between the grinding disc and the grinding ring, and is characterized in that the grinding ring, at least near its top, presents a conical structure with a gradually expanding diameter from top to bottom.

[0008] In order to improve the grinding efficiency, at least two shearing cuts are arranged on the peripheral wall of the grinding ring along its circumference, each of the shearing cuts passes through the bottom of the grinding ring, and the shearing cuts play a role in shearing garbage.

[0009] In order to further improve the grinding efficiency, a grinding hammer is provided on the top wall surface of the grinding disc near its peripheral edge, and the shearing opening and the grinding hammer cooperate to achieve high shearing and grinding efficiency for the garbage.

[0010] In order to further improve the grinding efficiency, the grinding ring includes an upper part and a lower part which are sequentially arranged and connected from top to bottom, the upper part is a conical structure with a gradually expanding diameter from top to bottom, and the lower part is a flat structure extending vertically. Compared with the existing grinding rings with vertical structures, the grinding ring of the present application has a larger contact area with the garbage and a higher grinding efficiency for the same height.

[0011] In order to further improve the grinding efficiency, the wall surface of the grinding hammer facing the grinding ring includes an inclined surface and a vertical surface which are sequentially arranged and connected from top to bottom. The inclined surface is inclined from top to bottom toward the grinding ring, and the inclined surface corresponds to the upper part of the grinding ring. The vertical surface extends vertically and corresponds to the lower part of the grinding ring. Compared with the method in which the wall surface of the grinding hammer is all vertical, the grinding hammer of the same height has a large contact area with the garbage and a high grinding efficiency.

[0012] In order to adapt to garbage of different sizes, at least two of the cutting openings have different sizes.

[0013] Preferably, at least one of the shearing openings is in a structure that is small at the top and large at the bottom, which has a higher shear strength on the garbage.

[0014] In the above scheme, at least one of the cuts is in a triangular structure that is small at the top and large at the bottom, and the other cuts are in the shape of strips extending from top to bottom. The shape of the cuts is simple and easy to open.

[0015] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a kitchen waste disposer, comprising a shell and the above-mentioned grinding structure, the shell having a grinding chamber inside, the grinding structure being arranged in the grinding chamber, the shell being provided with a feed inlet connected to the grinding chamber and located above the grinding structure, the shell also being provided with a discharge port connected to the grinding chamber and located below the grinding structure.

[0016] In order to facilitate the flow of garbage to the discharge port, the discharge port is arranged on the side wall of the shell corresponding to the grinding chamber, and the bottom wall of the grinding chamber, at least the part close to the peripheral edge, is inclined from top to bottom toward the side wall of the shell, so that the garbage can slide downward along the inclined surface to the discharge port under the action of its own gravity, thereby preventing garbage from accumulating in the grinding chamber.

[0017] Compared with the prior art, the utility model has the following advantages: the utility model designs the grinding ring, at least the position adjacent to its top, to be a conical structure with a gradually expanding diameter from top to bottom, that is, the top of the grinding ring is a closed structure, so that when the garbage splashes upwards, it will be blocked by the conical structure and then fall back onto the grinding ring, which can prevent the garbage from splashing out from the feed outlet, and confine the garbage to the space enclosed by the grinding ring and the conical structure for cutting, thereby ensuring cutting efficiency.

A gap 21 is provided between the outer circumference of the grinding disc 2 and the inner wall surface of the grinding ring 3. The grinding disc 2 and the grinding ring 3 can generate relative rotation. The axis of the grinding disc 2 is parallel to or coincides with the axis of the grinding ring 3. In this embodiment, the housing 1 is further provided with a driving mechanism 4 located below the grinding chamber 11. The output shaft 41 of the driving mechanism 4 extends into the grinding chamber 11 and is connected to the grinding disc 2, so that the grinding disc 2 rotates around its axis and the grinding ring 3 is fixed.

[0025] At least two shearing cuts 31 are arranged on the peripheral wall of the grinding ring 3 along its circumference, and each shearing cut 31 passes through the bottom of the grinding ring 3. A grinding hammer 5 is also arranged on the top wall of the grinding disc 2 near its peripheral edge. The shearing cut 31 and the grinding hammer 5 cooperate to achieve high shearing and grinding efficiency for garbage.

[0026] At least two of the shearing openings 31 have different sizes to accommodate garbage of different sizes. At least one of the shearing openings 31 has a structure that is smaller at the top and larger at the bottom, which has a higher shear strength for the garbage.

[0027] In this embodiment, at least one of the cutting cuts 31 is in a triangular structure that is small at the top and large at the bottom, and the other cutting cuts 31 are in the shape of strips extending from top to bottom. The shapes of the cutting cuts 31 are simple and easy to open.
