Technical Field

[0001] The utility model belongs to the technical field of garbage disposal, and in particular relates to a grinding system for a kitchen waste disposer and a kitchen waste disposer. Background Art

[0002] At present, there are many types of grinding system designs for food waste disposers on the market, but their structures are generally similar. They are all based on grinding discs and grinding rings with grinding hammers, and have been improved and optimized in different directions to improve the grinding effect and speed of food waste.

[0003] For example, the Chinese utility model patent "A grinding system for a kitchen waste disposer" with patent number 202320967186.2 and authorization announcement number CN219690666U includes a grinding cover with a grinding ring and a grinding disc installed in the grinding cover. The grinding disc rotates relative to the grinding ring under the drive of a driving mechanism. A grinding disc is fixed to the bottom of the grinding disc. A first curved portion with an opening facing upward is formed on the outer periphery of the grinding disc. The first curved portion extends outward from the outer edge of the grinding disc. The lower part of the grinding ring extends into the first curved portion with a gap left. A first blanking hole is opened on the first curved portion, thereby increasing the grinding area and effectively improving the grinding effect.

[0004] However, the grinding effect and efficiency of the existing grinding system for food waste disposers need to be further improved. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a grinding system for a kitchen waste disposer in view of the current status of the prior art, so as to improve the grinding efficiency.

[0006] The second technical problem to be solved by the present invention is to provide a grinding system for a kitchen waste disposer to improve the grinding fineness.

[0007] The third technical problem to be solved by the present utility model is to provide a kitchen waste disposer having the above-mentioned grinding system.

[0008] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a grinding system for a kitchen waste disposer, comprising:

[0009] A grinding cover having a grinding chamber therein;

[0010] A grinding ring, disposed in the grinding chamber and having a circumferentially extending side ring wall;

[0011] A grinding disc, which is horizontally placed in the grinding chamber and on the inner periphery of the grinding ring;

[0012] A driving mechanism, the output end of which acts on the grinding disc to drive the grinding disc to rotate circumferentially relative to the grinding ring;

[0013] Features:

[0014] At least the portion of the side ring wall of the grinding ring located above the grinding disk surface is inclined outward from top to bottom to form an inclined wall, and the inner wall surface of the inclined wall encloses a chamber with a small upper end and a large lower end. The outer wall surface of the inclined wall is spaced opposite to the inner side surface of the grinding chamber to form an annular chamber with a large upper end and a small lower end, and a through hole penetrating the wall thickness is opened on the inclined wall to allow the garbage ground in the chamber to pass through the through hole and enter the annular chamber.

[0015] In this way, the design of the inclined wall in the utility model can effectively prevent the mixture of garbage and water from splashing in the vertical upward direction under the action of centrifugal force, and control the mixture of garbage and water to be ground in the chamber surrounded by the inclined wall, thereby improving the grinding fineness and reducing the garbage residue in the upper part of the grinding chamber. At the same time, the ground garbage can enter the annular chamber through the through hole under the centrifugal force and the squeezing force of the remaining unground garbage. The annular chamber with a large upper end and a small lower end has a large capacity, ensuring that the ground garbage can continuously enter through the through hole and then be output through the bottom opening of the annular chamber, thereby ensuring improved grinding efficiency.

[0016] Preferably, the through hole is in the shape of a long strip extending up and down, and there are multiple through holes arranged on the inclined wall at intervals along the circumferential direction.

[0017] Preferably, at least part of the upper edges of the through holes are provided with protrusions extending inward. When the garbage collides with the protrusions, the protrusions can produce cutting and tearing forces on the garbage, so that the particle size of the garbage gradually becomes smaller. At the same time, the protrusions cooperate with the inclined walls to further prevent the mixture of garbage and water from splashing in a vertical upward direction under the action of centrifugal force.

[0018] Furthermore, the protrusion is perpendicular to the inclined wall.

[0019] Furthermore, the protrusions are staggered in the up-down direction.

[0020] Furthermore, at least part of the lower ends of the through holes are opened at the lower edge of the side ring wall of the grinding ring, so that part of the ground garbage can flow downward through the lower end openings of the through holes.

[0021] In the above solution, preferably, the grinding disc includes:

[0022] A disc-shaped body connected to the output end of the driving mechanism;

[0023] A grinding hammer is arranged on the top surface of the disc-shaped body, and a side surface of the grinding hammer is partially opposite to the inner wall surface of the inclined wall.

[0024] Preferably, the side surface of the grinding hammer is partially stepped to match the inner wall surface of the inclined wall. The stepped side surface of the grinding hammer can improve the grinding effect.

[0025] Preferably, the grinding hammer is arranged on the disc-shaped body in a manner that it can rotate around a rotating shaft extending up and down, and a protrusion is arranged on the side of the grinding hammer at a position avoiding the step shape. Under the impact of garbage, the grinding hammer can rotate around the rotating shaft, reducing the risk of jamming, and the rotating grinding hammer can increase its kinetic energy to generate a greater impact force on the garbage, thereby improving the grinding effect and speed.

[0026] Preferably, the lower portion of the side ring wall of the grinding ring is a first vertical wall extending vertically downward from the lower edge of the inclined wall, and the inner wall surface of the first vertical wall is opposite to the side edge of the disc-shaped body.

[0027] In the above schemes, preferably, the upper part of the side ring wall of the grinding ring is a second vertical wall extending vertically upward from the upper edge of the inclined wall, and a flange folded outward from the upper edge of the second vertical wall, and the flange is directly or indirectly supported on the supporting surface in the grinding chamber.

[0028] In the above schemes, preferably, a cutting disc is further included, which is arranged below the grinding disc and can rotate with the grinding disc, and the peripheral edge of the cutting disc is a toothed body, and is located below the grinding ring and outside the grinding disc. The cutting disc can cut the ground garbage.

[0029] Preferably, it further comprises a fixed grinding disc located in the grinding cover and fixed relative to the grinding cover, the fixed grinding disc having a bottom wall and a side wall extending upward from the periphery of the bottom wall, the bottom wall being located below the cutting disc, the side wall being located between the side ring wall and the inner side surface of the grinding chamber, and the side wall and the lower part of the side ring wall being spaced opposite to each other to form an annular gap, the annular gap being located below the annular chamber and the two being connected;

[0030] At the same time, the bottom wall and / or side wall of the fixed grinding disc is provided with a material passing hole penetrating the wall thickness so as to allow the ground garbage to pass through.

[0031] Furthermore, the bottom wall of the fixed grinding disc comprises a central portion and a peripheral portion located outside the central portion, the central portion is located above the peripheral portion and the two are connected by a step;

[0032] At least the peripheral portion is provided with the above-mentioned material passing hole.

[0033] The above steps can serve to block garbage.

[0034] Furthermore, part of the teeth on the cutting disk is located at the periphery of the side ring wall.

[0035] In this way, the garbage in the annular cavity can enter the annular gap and be cut and ground under the action of the cutting disc and the fixed grinding disc, thereby improving the grinding effect.

[0036] 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 system as described above.

[0037] Compared with the prior art, the utility model has the following advantages: the design of the inclined wall in the utility model can effectively prevent the mixture of garbage and water from splashing in the vertical upward direction under the action of centrifugal force, and control the mixture of garbage and water to be ground in the chamber surrounded by the inclined wall, thereby improving the grinding fineness and reducing the garbage residue in the upper part of the grinding chamber. At the same time, the ground garbage can enter the annular chamber through the through hole under the centrifugal force and the squeezing force of the remaining unground garbage. The annular chamber with a large upper end and a small lower end has a large capacity, ensuring that the ground garbage can continuously enter through the through hole and then be output through the bottom opening of the annular chamber, thereby ensuring improved grinding efficiency.

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] like Figures 1 to 6 As shown, a grinding system for a food waste disposer and a preferred embodiment of the food waste disposer of the present invention are shown, and the grinding system includes a grinding cover 1, a grinding ring 2, a grinding disc 3, a driving mechanism 4, a cutting disc 5 and a fixed grinding disc 6.

[0046] The grinding cover 1 is hollow inside to form a grinding chamber 10. The grinding chamber 10 has a feed inlet 10a at the top and a discharge outlet 10b at the bottom.

[0047] The grinding ring 2 is arranged in the grinding chamber 10 and has a circumferentially extending side ring wall 20. The side ring wall 20 has a circular inclined wall 21 located in the middle and inclined outward from top to bottom, a first vertical wall 24 extending vertically downward from the lower edge of the inclined wall 21, a second vertical wall 25 extending vertically upward from the upper edge of the inclined wall 21, and a flange 26 extending horizontally outward from the upper edge of the second vertical wall 25. The flange 26 is supported on the supporting surface in the grinding chamber 10 through an annular buffer 27, and the position of the flange 26 relative to the grinding chamber is fixed. The inner wall surface of the inclined wall 21 encloses a chamber 22 with a small upper end and a large lower end, and the outer wall surface of the inclined wall 21 is spaced opposite to the inner side surface of the grinding chamber 10 to form an annular chamber 23 with a large upper end and a small lower end, and through holes 210 penetrating the wall thickness are arranged on the inclined wall 21 at intervals along the circumference, so that the garbage ground in the chamber 22 can pass through the through holes 210 and enter the annular chamber 23. In this embodiment, each through hole 210 is in the shape of a strip extending vertically, and the upper edge of some through holes 210 is provided with a protrusion 211 extending inward and perpendicular to the inclined wall 21, and each protrusion 211 is staggered in the vertical direction. The lower end of some through holes opens to the lower edge of the side ring wall 20 of the grinding ring 2 to allow the ground garbage to pass through.

[0048] The grinding disc 3 includes a circular disc-shaped body 31 and a grinding hammer 32. The disc-shaped body 31 is horizontally placed in the grinding chamber 10 and the inner periphery of the grinding ring 2. The side of the disc-shaped body 31 is spaced apart from and opposite to the first vertical wall 24 of the grinding ring 2. The disc-shaped body 31 is connected to the output end of the driving mechanism 4 (a motor), and can rotate around its own central axis relative to the grinding ring 2 under the drive of the driving mechanism 4. The grinding hammer 32 is arranged on the top surface of the disc-shaped body 31 in a manner that it can rotate around a rotating shaft 321 extending up and down, and the side part 320 of the grinding hammer 32 is opposite to the inner wall surface of the inclined wall 21 and is in a stepped shape that matches the inner wall surface of the inclined wall 21. For details, please refer to Figure 4 , 5 A protrusion 322 is provided on the side of the grinding hammer 32 away from the step-shaped position. When the garbage hits the protrusion 322, the grinding hammer 32 can rotate around the rotating shaft 321, thereby increasing the kinetic energy of the grinding hammer.

[0049] The fixed grinding disc 6 is located in the grinding cover 1 and fixed relative to the grinding cover 1. The fixed grinding disc 6 has a bottom wall 61 and a side wall 62 extending upward from the periphery of the bottom wall 61. The bottom wall 61 is located below the grinding disc 3 and has a central part 611 and a peripheral part 612 located outside the central part 611. The central part 611 is located above the peripheral part 612 and the two are connected by a step 613. The side wall 62 is located between the first vertical wall 24 of the side ring wall 20 and the inner side of the grinding chamber 10, and the side wall 62 and the first vertical wall 24 are spaced opposite to each other to form an annular gap 620. The annular gap 620 is located below the annular chamber 23 and the two are connected. At the same time, the bottom wall 61 and the side wall 62 of the fixed grinding disc 6 are both circumferentially spaced with a feed hole 60 that penetrates the wall thickness for the ground garbage to pass through. In this embodiment, the feed hole 60 is strip-shaped and radially extends from the central part 611 of the bottom wall 61 to the edge of the peripheral part 611, and then extends upward to the side wall 62. For details, please see Figure 4 , 6 .

[0050] like Figures 4 to 6 As shown, the cutting disc 5 is arranged below the grinding disc 3 and above the bottom wall 61 of the fixed grinding disc 6, and can rotate with the grinding disc 3. The periphery of the cutting disc 5 is a toothed body 51, which is located below the grinding ring 2 and outside the first vertical wall 24.

[0051] When in use, the kitchen waste falls into the grinding chamber 10 through the feed port 10a, and is initially ground under the action of the grinding disc 3 and the grinding ring 2. The waste after the initial grinding is divided into two parts. One part passes through the gap between the side of the disc-shaped body 31 and the first vertical wall 24 and falls into the toothed body 51 of the cutting disc 5 for cutting, and then is ground again under the action of the cutting disc 5 and the fixed grinding disc 6, and finally is discharged from the discharge port 10b through the feed hole 60 on the fixed grinding disc 6. The other part of the waste after the initial grinding passes through the through hole 210 and enters the annular chamber 23, and then falls into the annular gap 620, and is cut by the cutting disc 5, and is ground again under the action of the cutting disc 5 and the fixed grinding disc 6, and finally is discharged from the discharge port 10b through the feed hole 60 on the fixed grinding disc 6. In the whole process, the waste can be ground and cut at multiple levels, thereby improving the waste treatment effect.
