Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garbage disposal equipment, in particular to a garbage disposal device. BACKGROUND

[0002] The existing kitchen garbage mostly includes residual leaves, leftover food, fruit peels, fish bones, residues, used tea leaves, etc., and the current processing method is to directly put them into a garbage bag and then put them into a garbage can. This method is not only unhygienic, but also causes various hazards brought by food garbage, such as peculiar smell, rat damage, and large-scale reproduction of cockroaches. At present, a kitchen garbage disposal device is used to crush the garbage generated in the kitchen, which is mainly installed at the drain of a kitchen vegetable washing basin to process the food and living garbage generated after cooking and dining, and facilitates the crushing and discharge of the kitchen garbage into the sewer pipe. In the existing garbage disposal device, in order to miniaturize the garbage disposal device, the use of a pump body is cancelled through structural design, for example, a method for improving the efficiency of residue removal and discharge of a dishwasher is disclosed in CN108283475A: 1) water and waste residue enter the third channel of the drain chamber, which is arranged at a position adjacent to the side wall of the drain chamber cavity, and the flow direction of the water in the channel is longitudinal downward; 2) a plurality of rotatable paddles are arranged in the drain chamber, the outer side of the paddle extends downward of the third channel, and the rotation track of the outer side extends horizontally across the lower part of the third channel; the paddle rotates to push the water and waste residue towards the side wall of the cavity of the drain chamber, and at the same time generates suction on the water in the third channel to increase the speed of the water and waste residue passing through the residue removal mechanism; 3) the outlet of the drain chamber is directed towards the rotation center of the paddle; when the outer side of the paddle approaches the outlet, the water and waste residue are pushed into the outlet and discharged from the drain. The paddle pushes the water and waste residue to increase the speed of the waste residue entering the outlet; at the same time, the paddle and the cavity form a pumping function to generate suction on the fluid in the residue removal mechanism. However, the existing garbage disposal device still has the problem of incomplete cutting, especially when encountering some fibrous substances with high toughness, it is difficult to cut, resulting in the fibrous substances winding around the fixed grinding disc and between the fixed grinding disc and the movable grinding disc, thereby causing the accumulation of waste residue and causing blockage. SUMMARY

[0003] The present application discloses a garbage disposal device, which aims to improve the problem of incomplete cutting in the existing garbage disposal device, and the accumulation of fibrous substances at the fixed disc and the blade, which causes the internal cleaning problem of the garbage disposal device.

[0004] The present application adopts the following scheme:

[0005] This application provides a waste disposer, including a mounting base and a fixed grinding disc and a movable grinding disc disposed within the mounting base. The mounting base forms a collection disc and a waste outlet. The collection disc is disposed below the fixed grinding disc and the movable grinding disc to collect waste passing through the fixed grinding disc and the movable grinding disc and discharge it from the waste outlet. The fixed grinding disc is circumferentially disposed around the outer edge of the movable grinding disc and includes a plurality of circumferentially distributed fixed plates. A waste discharge channel is formed between adjacent fixed plates, and the waste discharge channel extends through one end facing the collection disc. The movable grinding disc includes a central disc body and a blade body disposed below the central disc body. The edge of the blade body is provided with cutting teeth, which are located in the area below the fixed plates. A first waste discharge gap is formed between the upper surface of the cutting teeth and the bottom of the fixed plates. A second waste discharge gap is formed between the central disc body and the inner wall of the fixed plates.

[0006] Furthermore, a grinding cavity is formed between the cutting teeth, the intermediate disc, and the fixing plate.

[0007] Further, the cutting tooth includes a cutting surface and a smooth surface. The cutting surface faces the rotation direction of the blade body, and the angle between the cutting surface and the radial direction of the blade body is smaller than the angle between the smooth surface and the radial direction of the blade body. A first cutting tooth and a second cutting tooth are formed on the cutting surface. The first cutting tooth is located at the middle position of the cutting surface and has a first cutting angle facing away from the cutting surface. The second cutting tooth is located at the end of the cutting surface away from the blade body. The second cutting tooth includes a first cutting surface and a second cutting surface. The first cutting surface is parallel to the cutting surface, and the second cutting surface connects the end of the cutting tooth and the first cutting surface. The second cutting surface is inclined towards the blade body.

[0008] Furthermore, the second cutting tooth is provided with a second cutting angle, a third cutting angle and a fourth cutting angle, the second cutting angle and the third cutting angle are connected to the first cutting surface, and the third cutting angle and the fourth cutting angle are connected to the second cutting surface.

[0009] Furthermore, the fourth chamfer is located at the end of the cutting tooth, and the fourth chamfer is flush with the outer side of the fixing block or located inside the outer side of the fixing block.

[0010] Furthermore, a third cutting tooth is formed outward at the gap between adjacent cutting teeth, the third cutting tooth including a third cutting surface, wherein the fourth cutting surface is parallel to the cutting surface.

[0011] Furthermore, a first and a second paddle are formed below the blade body, arranged in a straight line. The first and the second paddles are adapted to push the waste residue on the collection plate to the waste residue outlet for discharge when the blade body rotates, and the first and the second paddles generate a suction force between the collection plate and the moving grinding plate when rotating.

[0012] Furthermore, the collection tray has a guide channel formed at the waste outlet, and the guide channel extends from the waste outlet in the opposite direction of the movement of the first and second paddles to form a guide slope inclined towards the waste outlet.

[0013] Furthermore, the upper surface of the intermediate disk is provided with a first grinding hammer and a second grinding hammer arranged in a straight line, and the first grinding hammer and the second grinding hammer are provided with a plurality of grinding teeth on the plane facing the rotation direction of the intermediate disk.

[0014] Furthermore, the intermediate disc is also provided with several water passage holes and cutting blocks, and has flow guide grooves and breaking protrusions at its edge, with the flow guide grooves and breaking protrusions arranged at intervals.

[0015] Beneficial effects:

[0016] In this invention, a slag discharge channel extending through one end of the collection tray is provided to prevent fibrous impurities from becoming entangled on the fixing plate, allowing them to fall more easily from the discharge channel and be cut by the cutting teeth. Simultaneously, the first and second slag discharge gaps allow waste residue and wastewater to fall onto the collection tray. Here, kitchen waste can fall from the first and second slag discharge gaps, as well as the discharge channel, between the moving and fixed grinding discs, where the relative rotation between the two discs grinds and crushes the waste. By positioning the cutting teeth below the fixing plate, kitchen waste falling from the first, second, and discharge gaps can be cut by the cutting teeth. Furthermore, the rotation of the first and second slag discharge gaps also allows for pulling and grinding of the kitchen waste, thereby improving crushing efficiency. Further, the design of the cutting teeth structure effectively improves cutting efficiency and prevents fibrous materials from becoming entangled between the cutting teeth and the fixing plate, thus preventing blockage.

[0036] Example

[0037] Combination Figures 1 to 4 As shown, this embodiment provides a waste disposer, including a mounting base 2 and a fixed grinding disc 5 and a movable grinding disc 3 disposed within the mounting base 2. The mounting base 2 forms a collection disc 22 and a waste outlet 24. The collection disc 22 is disposed below the fixed grinding disc 5 and the movable grinding disc 3 to collect waste passing through the fixed grinding disc 5 and the movable grinding disc 3 and discharge it from the waste outlet 24. The fixed grinding disc 5 is circumferentially disposed around the outer edge of the movable grinding disc 3 and includes a plurality of circumferentially distributed fixed plates 51, with adjacent fixed plates 51 forming a... There is a slag discharge channel 52, which extends through one end toward the collection plate 22; the moving grinding disc 3 includes an intermediate disc body 31 and a blade body 4 disposed below the intermediate disc body 31, the edge of the blade body 4 is provided with cutting teeth 42, the cutting teeth 42 are located in the area below the fixed plate 51, and there is a first slag discharge gap 61 between the upper plane of the cutting teeth 42 and the bottom of the fixed plate 51; a second slag discharge gap 62 is formed between the intermediate disc body 31 and the inner wall of the fixed plate 51.

[0038] Combination Figure 1 and Figure 2 As shown, in this embodiment of the invention, the garbage disposal unit includes a housing 1, a drive motor 12, a mounting base 2, a moving grinding disc 3, and a fixed grinding disc 5, etc., and all components are detachable. The drive motor 12 is adapted to drive the moving grinding disc 3 to rotate relative to the fixed grinding disc 5. A waste residue outlet 24 is formed on the mounting base 2, which is adapted to discharge the waste residue and wastewater processed by the moving grinding disc 3 and the fixed grinding disc 5. A food waste inlet 11 is formed on the housing 1 above the mounting base 2, and the food waste inlet 11 connects to the space enclosed by the moving grinding disc 3 and the fixed grinding disc 5.

[0039] Combination Figure 3 and Figure 5As shown, in this embodiment, the mounting base 2 includes an internally formed receiving cavity, which is suitable for mounting the moving grinding disc 3 and the fixed grinding disc 5. The mounting base 2 also includes a collecting disc 22, and a collecting cavity 21 suitable for accommodating waste residue is formed between the collecting disc 22 and the moving grinding disc 3. Positioning blocks 25 suitable for cooperating with the fixed grinding disc 5 are provided on the inner side of the mounting base 2. The positioning blocks 25 can be directly engaged in the slag discharge channel 52 of the fixed grinding disc 5, thereby fixing the fixed grinding disc 5 within the mounting base 2. Multiple positioning blocks 25 can prevent the fixed grinding disc 5 from rotating. Since the slag discharge channel 52 is designed to extend through one end towards the collecting disc 22, the fixed grinding disc 5 can be directly placed into the mounting base 2, and installation is completed by matching the positions of the positioning blocks 25 and the slag discharge channel 52. To further secure the fixed grinding disc 5, it can also be locked from the side using bolts 14 or screws. The thickness of the positioning block 25 is less than the thickness of the fixing piece 51, so that the slag discharge channel 52 with the positioning block 25 engaged can also perform the function of slag discharge. The collection tray 22 forms a guide groove 23 at the waste slag outlet 24. The guide groove 23 extends from the waste slag outlet 24 in the opposite direction of the movement of the first paddle 43 and the second paddle 44 to form a guide slope inclined towards the waste slag outlet 24. Through the design of the guide groove 23, the waste slag can be guided to the starting point of the guide slope during the rotation of the paddle, and flow out of the waste slag outlet 24 through the guide groove 23. Furthermore, the guide groove 23 forms a blocking slope 231 on one side of the waste slag outlet 24. The blocking slope 231 can impact the blocking slope 231 when the waste slag and wastewater are guided to the waste slag outlet 24 by the paddle, so that the waste slag and wastewater form a movement direction perpendicular to the blocking slope 231, thereby quickly flowing out of the waste slag outlet 24.

[0040] Combination Figure 3 and Figure 6 As shown, the fixed grinding disc 5 can be configured as an annular body, suitable for insertion into the mounting base 2. The fixed grinding disc 5 includes fixed plates 51 arranged around its circumference, and a through slag discharge channel 52 is formed between adjacent fixed plates 51. The distance between the fixed plates 51 can be the same, or different sizes can be set, that is, the width of the slag discharge channel 52 can be set to different sizes. In a preferred embodiment, the slag discharge channel 52 of different sizes can form a more fine and diverse grinding effect on the kitchen waste, further improving the crushing ability of kitchen waste. An inwardly protruding crushing body 53 is provided on the inner side of the fixed grinding disc 5. The crushing body 53 can crush the rotating kitchen waste at the edge of the fixed grinding disc 5, improving the kitchen waste processing efficiency.

[0041] Combination Figures 7 to 12As shown, the moving grinding disc 3 includes an intermediate disc body 31 and a blade body 4 disposed below the intermediate disc body 31. The intermediate disc body 31 and the blade body 4 are fixed by two connecting blocks 13, which are locked together by bolts 14 to secure the intermediate disc body 31 and the blade body 4. The bolts 14 are also locked onto the rotating shaft of the drive motor 12, so that the moving grinding disc 3 can rotate under the drive of the drive motor 12. A first grinding hammer 32 and a second grinding hammer 33 are arranged in a straight line on the upper plane of the intermediate disc 31. The first grinding hammer 32 and the second grinding hammer 33 are provided with a plurality of grinding teeth 321 on the plane facing the rotation direction of the intermediate disc 31. The first grinding hammer 32 and the second grinding hammer 33 can rotate with the intermediate disc 31, thereby pounding the kitchen waste falling on the intermediate disc 31. The first grinding hammer 32 and the second grinding hammer 33 include a grinding plane 322, which is a plane facing its movement direction, and the grinding plane 322 is provided with a plurality of grinding teeth. The grinding teeth 321 can be set as a four-sided pyramid, so that the kitchen waste in front of them can be quickly crushed during high-speed rotation. Furthermore, an arc-shaped block is provided at the end of the grinding hammer near the fixed plate 51, and the arc-shaped block includes a first arc-shaped block 323 and a second arc-shaped block 324. An arc-shaped channel 325 is formed between the first arc-shaped block 323 and the second arc-shaped block 324. Several impact strips 326 with increasing width are provided on the arc-shaped channel 325. The multiple impact strips 326 form a stepped shape, so that the kitchen waste will not accumulate at the arc-shaped block, and will move towards the fixed plate 51 under the guidance of the arc-shaped block and the arc-shaped channel 325 to enter the grinding chamber 63 for cutting and grinding. In addition, the stepped impact strips 326 and the arc-shaped channel 325 can make the waste be impacted multiple times by the impact strips 326 when passing through the arc-shaped channel 325. The stepped impact strips 326 can impact the kitchen waste step by step, thereby quickly and initially breaking it down. The arc-shaped channel 325 described here is lower than the plane of the first arc-shaped block 323 and the second arc-shaped block 324. When the grinding hammer rotates, a negative pressure can be formed at the arc-shaped channel 325, thereby attracting food waste into the arc-shaped channel 325. This helps the food waste move quickly within the mounting base 2 and be quickly diverted to the area around the fixing plate 51. In a preferred embodiment, the grinding plane 322 can also be set as an inclined plane, which helps guide the food waste to the area around the fixing plate 51 during the grinding and crushing process.

[0042] Combination Figure 7 and Figure 8As shown, the side of the blade body 4 extends downward to form a bent surface 41, and at the end of the bent surface 41, there are outwardly perpendicular cutting teeth 42. The cutting teeth 42 are parallel to or slightly inclined to the plane of the main body of the blade body 4. Here, the cutting teeth 42, the intermediate disc 31, and the fixing plate 51 form a grinding chamber 63. Kitchen waste flowing in from the slag discharge channel 52 and the second slag discharge channel 52 can flow into the cutting teeth 42 through the grinding chamber 63 and be cut and broken by the cutting teeth 42. Here, since the fixing plate 51 is vertically downward, fibrous waste is less likely to get tangled in the slag discharge channel 52 of the fixing plate 51.

[0043] Continue to combine Figure 7 and Figure 8As shown, the cutting tooth 42 here includes a cutting surface 421 and a smooth surface 422. The cutting surface 421 is oriented toward the rotation direction of the blade body 4, and the angle between the cutting surface 421 and the radial direction of the blade body 4 is smaller than the angle between the smooth surface 422 and the radial direction of the blade body 4. This makes the distance of the cutting surface 421 from the blade body 4 smaller than the distance of the smooth surface 422 from the blade body 4. That is, the cutting tooth 42 is inclined toward its direction of movement, which can improve the cutting force. The cutting surface 421 has a first cutting tooth 4211 and a second cutting tooth 4212 formed upwards. The first cutting tooth 4211 is located at the middle position of the cutting surface 421 and is provided with a first cutting angle facing away from the cutting surface 421. The second cutting tooth 4212 is provided at the end of the cutting surface 421 away from the blade body 4. The second cutting tooth 4212 includes a first cutting surface 4213 and a second cutting surface 4214. The first cutting surface 4213 is parallel to the cutting surface 421. The second cutting surface 4214 connects the end of the cutting tooth 42 and the first cutting surface 4213, and the second cutting surface 4214 is inclined towards the blade body 4. Both the first cutting tooth 4211 and the second cutting tooth 4212 can achieve the cutting and crushing effect during rotation. Since both the first cutting tooth 4211 and the second cutting tooth 4212 are set along the cutting surface 421, when the fibrous kitchen waste is first cut by the first cutting tooth 4211, it will be thrown to the second cutting tooth 4212 for secondary cutting under the action of inertia, so that the cutting is more delicate. In addition, the second cutting surface 4214 is inclined inward, thus forming a similar effect to a guide surface at the sharp corner of the cutting tooth 42. After the fibrous material is cut by the second cutting tooth 4212, it will slide down along the second cutting surface 4214, and will not cause the limiting material to entangle and accumulate at the end due to the end being too sharp. Furthermore, a second cutting angle 4215, a third cutting angle 4216, and a fourth cutting angle 4217 are provided on the second cutting tooth 4212. The second cutting angle 4215 and the third cutting angle 4216 connect to the first cutting surface 4213, and the third cutting angle 4216 and the fourth cutting angle 4217 connect to the second cutting surface 4214. Here, the second cutting angle 4215, the third cutting angle 4216, and the fourth cutting angle 4217 can all cut and crush kitchen waste, improving the crushing effect. The multi-cutting angle setting is more effective in crushing kitchen waste than a single cutting angle, resulting in higher crushing efficiency and a finer effect. Here, the fourth cutting angle 4217 is located at the end of the cutting tooth 42, and the fourth cutting angle 4217 is flush with the outer surface of the fixing block or located inside the outer surface of the fixing block.That is, the fourth cutting angle 4217 is located within the range of the fixing piece 51, and cutting is performed in the area below the fixing piece 51. Preferably, it can be set directly below the fixing piece 51. This setting can prevent the cutting teeth 42 from easily getting tangled with fibrous materials between them and the fixing piece 51 when the cutting teeth 42 exceed the range of the fixing piece 51. This setting can also ensure that the kitchen waste falling from the slag discharge channel 52 and the second slag discharge gap 62 can fall into the cutting range of the cutting surface 421. In a preferred embodiment, a third cutting tooth 4218 is formed outward at the gap between adjacent cutting teeth 42. The third cutting tooth 4218 includes a third cutting surface 4219, wherein the fourth cutting surface is parallel to the cutting surface 421. Here, the third cutting tooth 4218 can increase the cutting range of the cutting teeth 42, and the third cutting tooth 4218 cooperates with the first cutting tooth 4211 and the second cutting tooth 4212 to form a multi-level step-by-step cutting effect.

[0044] Continue to combine Figures 7 to 9 As shown, the edge of the blade body 4 is provided with a downwardly perpendicular bending surface 41, and cutting teeth 42 are provided on the bending surface 41 perpendicular to the bending surface 41, so that there is a certain height difference between the blade body 4 and the plane of the cutting teeth 42. This height difference allows the grinding cavity 63 to be formed between the bending surface 41, the cutting teeth 42 and the fixing plate 51. The kitchen waste can be continuously squeezed and ground in the grinding cavity 63, and then slowly fall into the gap of the adjacent cutting teeth 42 and be cut and broken by the cutting teeth 42. Below the blade body 4, a first paddle 43 and a second paddle 44 are arranged in a straight line. The first paddle 43 and the second paddle 44 are adapted to push the waste residue on the collection plate 22 to the waste residue outlet 24 for discharge when the blade body 4 rotates. When the first paddle 43 and the second paddle 44 rotate, a negative pressure is formed between the collection plate 22 and the moving grinding plate 3, thereby generating a suction force above the moving grinding plate 3 to accelerate the entry of kitchen waste into the grinding chamber 63 and into the collection chamber 21.

[0045] Combination Figure 10 and Figure 11As shown, in another embodiment, the intermediate disc 31 is further provided with a plurality of water passage holes 34 and cutting blocks 35, and has flow guide grooves 37 and crushing protrusions 36 at its edges, with the flow guide grooves 37 and crushing protrusions 36 arranged at intervals. The water passage holes 34 allow wastewater to fall, preventing it from falling entirely through the slag discharge channel 52 and the slag discharge gap, thus reducing noise generated during wastewater cutting and improving the efficiency of food waste treatment. The cutting blocks 35 assist in cutting, initially crushing the food waste above the intermediate disc 31 before it enters the grinding chamber 63. The specific positions of the water passage holes 34 and cutting blocks 35 are not limited and can be distributed dispersed above the intermediate disc 31. A flow guide groove 37 and a crushing protrusion 36 are provided on the edge of the intermediate disc 31. The flow guide groove 37 and the crushing protrusion 36 are arranged alternately on the circumference. The flow guide groove 37 facilitates the flow of wastewater or waste residue into the grinding chamber 63, while the crushing protrusion 36 can achieve a cutting effect. The kitchen waste that is thrown to the edge of the intermediate disc 31 under centrifugal force is crushed and then falls into the second slag discharge gap 62 after being crushed. The flow guide groove 37 protrudes from the bottom of the intermediate disc 31, forming a bottom crusher 371 between the intermediate disc 31 and the blade body 4. The bottom crusher 371 can crush the kitchen waste that enters the gap between the blade body 4 and the intermediate disc 31. Since a water passage hole 34 is provided on the intermediate disc 31, wastewater can fall from the water passage hole 34 and be discharged from the gap between the blade body 4 and the intermediate disc 31, while flushing out the waste residue between the blade body 4 and the intermediate disc 31.

[0046] In another embodiment, a sealing element 15 is provided between the fixed grinding disc 5 and the mounting base 2, and a sealing ring is provided on the sealing element 15 to prevent wastewater and waste residue from seeping out from the edge of the mounting base 2.

[0047] This invention improves cutting efficiency by optimizing the coordination between the intermediate disc 31, the blade body 4, and the fixed grinding disc 5. This also reduces the likelihood of fibrous debris entanglement causing blockages and deteriorating cutting results. Furthermore, the reduced fibrous debris minimizes the need for disassembling the outer casing, thus extending the equipment's lifespan.

[0048] It should be understood that the above are merely preferred embodiments of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.

[0049] The accompanying drawings used in the above description of the embodiments only illustrate certain embodiments of the present invention and should not be regarded as a limitation of the scope.
