Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a food waste disposer. Background Art

[0002] The food waste disposer is a common auxiliary equipment in modern kitchens. It is installed at the bottom of the sink and has a grinding structure inside. Food waste is directly flushed from the sink into the food waste disposer for crushing and grinding before being discharged into the sewer. For example, the patent application No. 201922191884.4 discloses a multi-stage chopping and grinding device for a food waste disposer, which includes a grinding ring and a knife disc assembly arranged in a lower crushing chamber, and a grinding chamber with an upper opening formed therein, the knife disc assembly is connected to the motor shaft and rotatably arranged in the grinding ring, and there is a grinding gap between the grinding ring and the knife disc assembly, the knife disc assembly includes a knife disc and a grinding disc, and the knife disc is provided with a grinding column, a stirring column and a grinding knife, the inner side of the upper part of the grinding ring is provided with an annularly distributed grinding ring convex teeth, the lower part of the grinding ring is provided with an annularly distributed grinding ring cutting teeth, and the outer circle of the grinding disc is provided with an annularly distributed grinding convex teeth and grinding flat teeth, and the grinding ring cutting teeth respectively cooperate with the grinding column, the grinding knife, the grinding convex teeth and the grinding flat teeth to stagger the food. Through the above arrangement, the food waste can be gradually ground and cut, the food waste is fully chopped from coarse grinding to fine grinding, and the ground food waste particles are smaller.

[0003] However, in reality, food waste contains both harder residues such as bones and softer long-fiber residues such as vegetables and fruit peels. Harder residues such as bones can be well processed after the above-mentioned grinding and cutting, but the softer long-fiber residues are difficult to be ground and processed because they are relatively soft and slender. As a result, the soft long-fiber residues will accumulate in the machine for a long time and cause blockage and jamming inside the machine. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and propose a food waste disposer to solve the problem of poor treatment effect on long fibers.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A food waste disposer comprises a shell, a grinding ring fixedly connected to the shell, and a grinding disc rotatably disposed in the shell, wherein a planar grinding structure is provided between the edge of the grinding disc and the bottom of the grinding ring, and wherein the bottom of the grinding disc is fixedly connected to a cutting plate, the edge of the cutting plate having a horizontally disposed cutting portion, the cutting portion being located below the edge of the grinding disc, and the edge of the cutting plate also having a plate-shaped water-repelling portion disposed downward.

[0007] When in use, the shell is fixedly connected to the bottom of the sink drain. When the sink is drained, the food waste is flushed into the shell of the food waste disposer and falls into the area formed by the upper side of the grinding disc and the inner side of the grinding ring. The grinding disc rotates at a high speed, so that the food waste is thrown to the inner wall of the grinding ring under the action of centrifugal force to be crushed and ground into a certain granular shape. Afterwards, the food waste particles enter between the edge of the grinding disc and the bottom surface of the grinding ring and are further ground and crushed in the horizontal direction by the flat grinding structure arranged between the two. The ground and crushed food waste particles continue to fall downward, and long fibers will continue to be squeezed out from the gap between the edge of the grinding disc and the bottom of the grinding ring.

[0008] Since the bottom of the grinding disc is fixedly connected with a cutting plate, the edge of the cutting plate has a cutting portion located below the edge of the grinding disc. When the cutting plate rotates at high speed together with the grinding disc, the cutting portion at the edge of the cutting plate will fully pull and cut the long fibers squeezed out from the gap between the edge of the grinding disc and the bottom of the grinding circle, so that the long fibers are continuously processed into thin and short limit pieces and are easier to discharge, thereby preventing the long fibers from gathering in the shell and causing blockage. In addition, the edge of the cutting plate also has a plate-shaped water-repelling portion arranged downward. When the cutting plate rotates, the water-repelling portion will move the water, and the water will form a rapid flow after being moved, so as to play a role in boosting pressure and preventing blockage when entering the sewer. Moreover, the cutting portion and the water-repelling portion are both arranged on the cutting plate, realizing the dual purpose of the cutting plate.

[0009] In the above-mentioned food waste disposer, the cutting portion includes a plurality of lower cutting teeth arranged horizontally, each lower cutting tooth is sawtooth-shaped and continuously distributed along the circumferential direction.

[0010] The cutting part is configured to include a plurality of lower cutting teeth arranged horizontally, each lower cutting tooth is sawtooth-shaped and continuously distributed along the circumference, so that each lower cutting tooth will cut the fiber during the rotation of the cutting plate, further improving the processing effect on the fiber.

[0011] In the above-mentioned food waste disposer, the number of the cutting parts is two and they are symmetrically distributed on the edge of the cutting plate, the number of the water-repelling parts is two, and the cutting parts and the water-repelling parts are arranged at intervals along the circumferential direction.

[0012] Through the above arrangement, the fiber cutting effect and the pressurization and anti-blocking effect can be further improved.

[0013] In the above-mentioned food waste disposer, the bottom of the cutting plate is also protruded with a triangular sheet-shaped action portion.

[0014] When the cutting plate rotates, the action part will pull the fibers cut by the cutting part, thereby further improving the processing effect on the fibers.

[0015] In the above-mentioned food waste disposer, the upper inner wall of the grinding ring is provided with a plurality of protrusions along the circumferential direction, the lower inner wall of the grinding ring is provided with first grinding teeth continuously distributed along the circumferential direction, the grinding disk comprises an upper disk body and a lower disk body which are fixed to each other, the upper disk body is located on the inner side of the lower part of the grinding ring, an extrusion piece is fixedly connected to the upper side of the upper disk body, the extrusion piece has an extrusion portion which is arranged toward the inner wall of the grinding ring, the lower disk body is located below the grinding ring and a planar grinding structure is arranged between the two, and the edge of the upper disk body has a material passing notch.

[0016] After the food waste is thrown to the inner wall of the grinding circle under the action of centrifugal force, the extrusion part of the extrusion piece will cooperate with the spurs and the first grinding teeth to grind and crush the food waste. The cooperation between the extrusion part and the spurs will process the food waste into larger particles. Since the first grinding teeth are continuously distributed along the circumference, the cooperation between the extrusion part and the first grinding teeth will quickly process the food waste in the form of larger particles into smaller particles. In addition, the edge of the upper disk body has a feed notch. If the food waste particles want to enter the space between the lower disk body and the bottom of the grinding circle for plane grinding, they must be processed by the extrusion part and the first grinding teeth to be smaller than the feed notch. This is equivalent to letting the feed notch block all larger particles so that they can only be continuously processed into small particles by the extrusion part and the first grinding teeth, ensuring the uniform size of the food waste particles before plane grinding.

[0017] In the above-mentioned food waste disposer, the feed notch has upper cutting teeth arranged horizontally.

[0018] Upper cutting teeth are horizontally arranged along the inner edge of the feeding gap. When the food waste particles crushed by the extrusion member and the first grinding teeth pass through the feeding gap, they will also be cut by the movement of the upper cutting teeth relative to the first grinding teeth. This can make the food waste particles smaller and easier to be ground by the planar grinding structure.

[0019] In the above-mentioned food waste disposer, a plurality of second grinding teeth are horizontally arranged along the edge of the lower disk body, and the planar grinding structure includes the bottom surface of the grinding ring and the upper side surfaces of each second grinding tooth. The bottom surface of the grinding ring is provided with a plurality of third grinding teeth protruding downward.

[0020] Conventional plane grinding structures are planes between teeth. In the present food waste disposer, a plurality of third grinding teeth protruding downward are added to the bottom of the grinding ring, so that the third grinding teeth also participate in the plane grinding, and the third grinding teeth can further grind and crush the food waste particles, so that the food waste particles can be processed into smaller particles during plane grinding.

[0021] Compared with the prior art, the food waste disposer has the following advantages:

[0022] 1. By fixing a cutting plate at the bottom of the grinding disc, the edge of the cutting plate has a cutting portion located below the edge of the grinding disc. When the cutting plate rotates at high speed along with the grinding disc, the cutting portion at the edge of the cutting plate will fully pull and cut the long fibers squeezed out from the gap between the edge of the grinding disc and the bottom surface of the grinding ring, so that the long fibers are continuously processed into short and thin limits and are easier to discharge, thus avoiding the long fibers from gathering in the housing and causing blockage;

[0023] 2. The edge of the cutting board is provided with a plate-shaped water-displacing part which is arranged downward. When the cutting board rotates, the water-displacing part will move the water, and the water will flow rapidly after being moved, so as to increase the pressure and prevent blockage when entering the sewer.

DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] like Figure 1-Figure 4 As shown, the food waste disposer comprises a housing 1, a grinding ring 2 fixedly connected to the housing 1, and a grinding disc 3 rotatably arranged in the housing 1, wherein a plane grinding structure is formed between the edge of the grinding disc 3 and the bottom surface of the grinding ring 2. Specifically, a thorn 2a1 is arranged on the inner wall of the upper part of the grinding ring 2 along the circumferential direction, and a first grinding tooth 2b1 is continuously distributed on the inner wall of the lower part of the grinding ring 2 along the circumferential direction. The grinding disc 3 comprises an upper plate body 3a and a lower plate body 3b fixed to each other, the upper plate body 3a is located on the inner side of the lower part of the grinding ring 2, an extrusion member 5 is fixed on the upper side of the upper plate body 3a, and the extrusion member 5 has an extrusion portion 5a arranged toward the inner wall of the grinding ring 2, and the lower plate body 3b is located below the grinding ring 2 and the plane grinding structure is arranged between the two. A plurality of second grinding teeth 3b1 are arranged horizontally along the edge of the lower plate body 3b, and the plane grinding structure comprises the bottom surface of the grinding ring 2 and the upper side surface of each second grinding tooth 3b1, and a plurality of third grinding teeth 2b2 protruding downward are arranged on the bottom surface of the grinding ring 2. In this embodiment, for the convenience of manufacturing, the grinding ring 2 includes an upper ring body 2a and a lower ring body 2b that are abutted against each other, the protrusion 2a1 is provided on the upper ring body 2a and the first grinding tooth 2b1 is provided on the lower ring body 2b, the outer diameter of the upper disk body 3a is slightly smaller than the inner diameter of the lower ring body 2b, the edge of the upper disk body 3a has a material passing notch 3a1, and the material passing notch 3a1 has an upper cutting tooth 3a2 arranged horizontally.

[0034] Furthermore, if Figure 1 , Figure 5 , Fig. 6A and Figure 6B As shown, a cutting plate 4 is fixedly connected to the bottom of the lower disk body 3b of the grinding disk 3, and the edge of the cutting plate 4 has a cutting portion 4a which is arranged horizontally and is in an arc shape, and the cutting portion 4a is located below the second grinding tooth 3b1. Among them, the cutting portion 4a is in an arc shape, and the cutting portion 4a includes a plurality of lower cutting teeth 4a1 which are arranged horizontally, and each lower cutting tooth 4a1 is serrated and continuously distributed along the circumferential direction. In this embodiment, the edge of the cutting plate 4 also has a water-repelling portion 4b which is arranged downward and is in the shape of a plate, and the number of the cutting portions 4a is two and is symmetrically distributed on the edge of the cutting plate 4, and the number of the water-repelling portions 4b is two, and the cutting portion 4a and the water-repelling portion 4b are arranged at intervals along the circumferential direction. The bottom of the cutting plate 4 also protrudes with an action portion 4c in the shape of a triangular sheet.

[0035] The housing 1 is fixedly connected to the bottom of the sink drain when in use. When the sink is drained, the food waste is flushed into the housing 1 of the food waste disposer and falls into the area formed by the upper side of the grinding disc 3 and the inner side of the grinding ring 2. A motor is arranged inside the food waste disposer, and the grinding disc 3 is fixedly connected to the output shaft of the motor. The grinding disc 3 rotates at a high speed, so that the food waste is thrown to the inner wall of the grinding ring 2 under the action of centrifugal force. The extrusion part 5a of the extrusion member 5 will cooperate with the spur 2a1 and the first grinding tooth 2b1 to grind and crush the food waste. The cooperation of the extrusion part 5a and the spur 2a1 will process the food waste into larger particles. The first grinding teeth 2b1 are continuously distributed along the circumference, so the cooperation of the extrusion part 5a and the first grinding teeth 2b1 will quickly process the food waste in the form of larger particles into smaller particles. In addition, the edge of the upper plate 3a has a feeding notch 3a1. If the food waste particles want to enter the space between the upper plate 3a and the bottom of the grinding ring 2 for plane grinding, they must be processed by the extrusion part 5a and the first grinding teeth 2b1 to be smaller than the feeding notch 3a1. This is equivalent to allowing the feeding notch 3a1 to block all larger particles from the outside so that they can only be continuously processed by the extrusion part 5a and the first grinding teeth 2b1 to be small particles, ensuring that the size of the food waste particles before plane grinding is uniform. In addition, because the feeding notch 3a1 is also provided with an upper cutting tooth 3a2, when the food waste particles pass through the feeding notch 3a1, they will also be cut by the movement of the upper cutting tooth 3a2 relative to the first grinding tooth 2b1, so that the food waste particles can become smaller and easier to be ground by the plane grinding structure.

[0036] Afterwards, the food waste particles are ground and crushed in the horizontal direction by the plane grinding structure through the material passing notch 3a1. Specifically, the grinding ring 2 remains stationary. During the high-speed rotation of the lower plate 3b, the upper side of each second grinding tooth 3b1 and the bottom surface of the grinding ring 2 generate relative motion to form grinding. Moreover, because a plurality of third grinding teeth 2b2 protruding downward are added to the bottom surface of the grinding ring 2, the third grinding teeth 2b2 will also participate in the plane grinding. The third grinding teeth 2b2 can further grind and crush the food waste particles, so that the food waste particles can be processed into smaller pieces during the plane grinding.

[0037] The ground and crushed food waste particles continue to fall downward, and the long fibers will continue to be squeezed out from the gap between the edge of the grinding disc 3 and the bottom of the grinding ring 2. Since the bottom of the grinding disc 3 is fixedly connected with the cutting plate 4, and the edge of the cutting plate 4 has a cutting portion 4a located below the edge of the grinding disc 3, when the cutting plate 4 rotates at high speed together with the grinding disc 3, the cutting portion 4a at the edge of the cutting plate 4 will fully pull and cut the long fibers squeezed out from the gap between the edge of the grinding disc 3 and the bottom of the grinding ring 2, so that the long fibers are continuously processed into thin and short limited portions and are easier to discharge, so that the long fibers can be prevented from gathering in the housing 1 and causing blockage. Moreover, because the bottom of the cutting plate 4 is also protruding with a triangular sheet-shaped action portion 4c, during the rotation of the cutting plate 4, the action portion 4c will pull the fibers cut by the cutting portion 4a, further improving the processing effect of the fibers.

[0038] In addition, since the edge of the cutting board 4 is provided with a plate-shaped water-repelling portion 4b disposed downward, the water-repelling portion 4b will move the water during the rotation of the cutting board 4, and the water will flow rapidly after being moved, thereby playing a role in pressurizing and preventing blockage when entering the sewer. Moreover, the cutting portion 4a and the water-repelling portion 4b are both disposed on the cutting board 4, realizing that the cutting board 4 has two uses.

[0039] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
