Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment, and particularly relates to a grinding assembly, a kitchen waste processor and a control method thereof. Background Art

[0002] Kitchen waste refers to food residues such as leftovers, vegetable stalks, and fruit peels left after each family finishes a meal. Ordinary families usually put these kitchen wastes into garbage bags and throw them into the community trash cans together with domestic garbage.

[0003] However, with the implementation of garbage classification, urban kitchen waste has become a major headache problem for people. The use of kitchen waste processors has solved some problems for people, so it is welcomed by the market.

[0004] The working principle of traditional processors is to break food residues by hitting and impacting them through an internal grinding mechanism. However, existing processors still cannot completely process food residues with flexible long fibers and high toughness (such as corn leaves, fruit peels, and vegetable leaves).

[0061] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "contacted", "communicated" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] As Figures 1-7 shown, the present invention provides a grinding assembly, which can be used in a kitchen waste processor, can effectively cut off difficult-to-clean garbage such as flexible long fibers, avoid problems such as aggregation or entanglement of garbage such as flexible long fibers, and effectively prevent the garbage from clogging the kitchen waste processor.

[0063] The grinding assembly includes a grinding ring 10 and a tool disc 20.

[0064] The cutter head 20 forms a disk surface, and the grinding ring 10 is disposed around the disk surface. The inner peripheral wall of the grinding ring 10 and the disk surface enclose a grinding cavity; the cutter head 20 can be controlled to rotate clockwise and counterclockwise relative to the grinding ring 10; a first cutting structure is formed on the periphery of the cutter head 20, and the first cutting structure includes a plurality of cutting teeth 21. A gap is formed between every two adjacent cutting teeth 21; the cutting teeth 21 have a connected root 211, a top 212 and opposite side portions 213. The root 211 is connected to the cutter head 20. In the radial direction of the cutter head 20, the root 211 is close to the center O of the cutter head, and the top 212 is far from the center O of the cutter head. In the rotation direction of the cutter head 20, the side portion 213 is inclined towards the clockwise direction or the counterclockwise direction.

[0065] As Figure 7 shown, the intersection of the root 211 and the side portion 213 is the first point a, the intersection of the top 212 and the side portion 213 is the second point b, the connection line between the first point a and the second point b is the first connection line L1, and the connection line between the first point a and the center O of the cutter head is the second connection line L2. Among them, the included angle between the first connection line L1 and the second connection line L2 is greater than 0° and less than 90°.

[0066] For example, the two opposite side portions 213 of the cutting teeth 21 can both be inclined towards the counterclockwise direction.

[0067] Preferably, at least one side portion 213 of the cutting teeth 21 is formed as an arc-shaped cutting edge. For example, the arc surface of the arc-shaped cutting edge can protrude towards the clockwise direction.

[0068] The inner peripheral wall of the grinding ring 10 is provided with a second cutting structure protruding towards the grinding cavity, and the second cutting structure can also be referred to as a cutting knife 11. The grinding ring 10 can extend axially into a cylindrical structure, and the cutting knife 11 can extend from the bottom of the grinding ring 10 towards its radial inner side. In one example, the cutting knife 11 includes a plurality of trapezoidal sawtooth knives and / or fan-shaped sawtooth knives, and the plurality of trapezoidal sawtooth knives or the plurality of fan-shaped sawtooth knives are arranged along the circumferential direction of the grinding ring. A gap is provided between every two adjacent trapezoidal sawtooth knives, or a gap is provided between every two adjacent fan-shaped sawtooth knives.

[0069] The cutter head 20 can rotate relative to the grinding ring 10. The cutter head 20 can be disposed inside the grinding ring 10 and installed on the drive motor shaft of the food waste processor. The drive motor drives the cutter head 20 to rotate relative to the grinding ring 10. A plurality of cutting teeth 21 are provided on the periphery of the cutter head 20. The cutting teeth 21 are located above the cutting knife 11. In the circumferential direction of the cutter head 20, the inclined edges of the plurality of cutting teeth 21 face the same direction. For example, the plurality of cutting teeth 21 all face the counterclockwise or clockwise direction. Among them, in the state where the cutter head 20 rotates relative to the grinding ring 10, the cutting teeth 21 cooperate with the cutting knife 11 to cut and / or grind an object (such as food waste).

[0070] During use, the cutter head 20 rotates at a high speed relative to the grinding ring 10. Multiple cutting teeth 21 on the periphery of the cutter head 20 cooperate with the cutting knife 11 up and down to shear and cut garbage such as flexible long fibers. After the garbage shearing and cutting process is completed, the cutter head 20 can be rotated in the opposite direction. Since the orientations of the multiple cutting teeth 21 on the periphery of the cutter head 20 are the same, when the cutter head 20 rotates in the opposite direction, the processed food residues can be smoothly discharged. For example, when the multiple cutting teeth 21 on the periphery of the cutter head 20 all face the clockwise direction, the clockwise rotation of the cutter head 20 causes the cutting teeth 21 to cooperate with the cutting knife 11 to process the garbage. After the process is completed, the cutter head 20 rotates counterclockwise so that the cutting teeth 21 smoothly discharge the processed garbage from the gap between the cutter head 20 and the grinding ring 10. Another example is that when the multiple cutting teeth 21 on the periphery of the cutter head 20 all face the counterclockwise direction, the counterclockwise rotation of the cutter head 20 causes the cutting teeth 21 to cooperate with the cutting knife 11 to process the garbage. After the process is completed, the cutter head 20 rotates clockwise so that the cutting teeth 21 smoothly discharge the processed garbage from the gap between the cutter head 20 and the grinding ring 10.

[0071] In some embodiments, as Figure 2 shown, the cutting teeth 21 on the periphery of the cutter head 20 are arc-shaped serrated knives. The multiple arc-shaped serrated knives face the same direction, for example, all face the counterclockwise direction. The multiple arc-shaped serrated knives can be formed by multiple arc-shaped notches or arc-shaped gaps opened on the periphery of the cutter head 20, and the circumferential sides of the notches or gaps are arc-shaped.

[0072] In other embodiments, as Figure 5 shown, the cutting teeth 21 on the periphery of the cutter head 20 are arc-shaped pointed bayonets. The multiple arc-shaped pointed bayonets with pointed edges face the same direction, for example, face the counterclockwise direction. In the case of the same quantity, compared with the arc-shaped serrated knives, the distance between two adjacent arc-shaped pointed bayonets in the shape of pointed knives from the inside to the outside is larger, which is convenient for discharging food residues.

[0073] In some embodiments, a breaker hammer 23 is provided on the cutter head 20. The first end of the breaker hammer 23, which serves as a connection end, is hinged to the cutter head 20. A third cutting structure may be provided at the bottom of the breaker hammer 23. The breaker hammer 23 can swing relative to the cutter head 20. In a state where the breaker hammer 23 swings relative to the cutter head 20, the third cutting structure at the bottom of the breaker hammer 23 can partially cover or completely cover the cutting teeth 21. The breaker hammer 23 and the cutting teeth 21 cooperate to cut and / or grind an object. The first end of the breaker hammer 23 is the end close to the center of the cutter head 20, and the second end of the breaker hammer 23 is the end far from the center of the cutter head 20, and is also the free end. The breaker hammer 23 can swing relative to the cutter head 20 with the first end as the axis. During the swinging process, the second end of the breaker hammer 23 sweeps (skims) over the cutting teeth 21 on the periphery of the cutter head 20 and cooperates with them to further grind and tear food waste such as long fibers, improving the food waste treatment efficiency. Two breaker hammers 23 may be provided, and the two breaker hammers 23 are symmetrically arranged relative to the center of the cutter head 20.

[0074] Limit bumps are provided on the cutter head 20 to limit the swinging stroke of the breaker hammer 23. The limit bumps include a first limit bump 24 and a second limit bump 25. In the circumferential direction of the cutter head 20, the first limit bump 24 and the second limit bump 25 are respectively located on both sides of the breaker hammer 23 to limit the forward and backward swinging stroke of the breaker hammer 23.

[0075] In some embodiments, as Figure 3 and Figure 5 shown, the grinding ring 10 is cylindrical. A plurality of first bumps 12 extending inward are provided on the inner wall of the grinding ring 10. The plurality of first bumps 12 are located above the cutting knife 11 and are arranged along the circumference of the grinding ring 10. A notch 231 that is recessed inward is provided at the second end of the breaker hammer 23, which serves as the free end. The notch 231 faces the inner peripheral wall of the grinding ring and corresponds to the first bump 12. The free end is far from the center of the disc. In a state where the breaker hammer 23 swings relative to the cutter head 20, the notch 231 passes by the first bump 12 and cooperates with the first bump 12 to cut an object. During the swinging process of the breaker hammer 23, the first bump 12 can be embedded in the knife notch 231 to cut and crush food waste such as long fibers. In other words, in a state where the breaker hammer 23 swings relative to the cutter head 20, the notch 231 skims over the first bump 12 and forms a cutting and / or grinding effect through clearance fit with the first bump 12. In addition, during the rotation of the cutter head 20, the breaker hammer 23 swings, so that the notch 231 on the breaker hammer 23 can pass by the first bumps 12 at different positions, thereby cutting and crushing food waste such as long fibers at different positions, making the food waste treatment more thorough.

[0076] In some embodiments, the first bump 12 includes an opposite first upper inclined surface and a first lower inclined surface. The first upper inclined surface and the first lower inclined surface are respectively inclined towards each other to form a triangle or trapezoid with a wide root and a pointed head. The shape of the notch 231 is adapted to the shape of the first bump 12, including an opposite second upper inclined surface 232 and a second lower inclined surface 233. The second upper inclined surface and the second lower inclined surface are respectively inclined towards each other to form a triangle or trapezoid. In a state where the breaker 23 swings relative to the cutter head 10, the notch 231 sweeps across the first bump 12, causing the first upper inclined surface to cooperate with the second upper inclined surface to cut an object, and the first lower inclined surface to cooperate with the second lower inclined surface to cut an object. By forming a multi-cutting and grinding structure through the cooperation of the upper and lower inclined surfaces of the notch with the upper and lower inclined surfaces of the first bump 12 respectively, the garbage disposal is more thorough. At the same time, the setting of the inclined surface can effectively prevent the entanglement of garbage such as long fibers and improve the processing efficiency.

[0077] Further, at the moment when the notch 231 sweeps across the first bump 12, the first gap formed between the first upper inclined surface and the second upper inclined surface gradually increases in the inclined direction of the second upper inclined surface; and / or, the second gap formed between the first lower inclined surface and the second lower inclined surface gradually increases in the inclined direction of the second lower inclined surface.

[0078] In some embodiments, the inner peripheral wall of the grinding ring 10 is further provided with one or more second bumps 13 protruding towards the grinding cavity. The plurality of second bumps 13 are located above the first bumps 12, and the plurality of first bumps 12 are arranged along the circumferential direction of the grinding ring 10. In a state where the breaker 23 swings relative to the cutter head 20, the upper surface of the breaker 23 passes over the second bumps 13 and is in clearance fit with the second bumps 13 to cut and / or grind an object. By forming an upper cutting and grinding structure through the cooperation of the second bumps 13 with the upper surface of the breaker 23, and at the same time, forming a lower cutting and grinding structure through the cooperation of the first bumps 12 with the notch 231 of the breaker 23, the grinding assembly has an upper and lower multi-stage cutting and grinding structure, and processes garbage such as long fibers in all directions at multiple upper and lower positions.

[0079] Further, the second bump 13 includes an opposite third upper inclined surface 132 and a third lower inclined surface 131. The third upper inclined surface 132 and the third lower inclined surface 131 are respectively inclined towards each other to form a triangle or trapezoid with a wide root and a pointed head. The upper surface of the breaker 23 has a fourth upper inclined surface 234, and the fourth upper inclined surface 234 is inclined downward. In a state where the breaker 23 swings relative to the cutter head 20, the fourth upper inclined surface 234 is in clearance fit with the third lower inclined surface 131 to cut and / or grind an object. By the cooperation of the lower inclined surface of the second bump 13 with the fourth upper inclined surface 234 of the upper surface of the breaker 23, not only an additional level of cutting and grinding structure is added, but also the setting of the inclined surface can effectively prevent the entanglement of garbage such as long fibers and improve the processing efficiency.

[0080] Preferably, a fourth upper inclined surface 234 formed on the upper surface of the breaker 23 and a second upper inclined surface formed by the breaker notch 231 are inclined towards each other to form a sharp edge.

[0081] A plurality of second bumps 13 and a plurality of first bumps 12 are arranged alternately, that is, in the circumferential direction of the grinding ring 10, the second bumps 13 and the plurality of first bumps 12 are arranged alternately. In this way, while the cutter head 20 rotates, the breaker 23 swings to form a multi-stage grinding structure at multiple circumferential positions, so as to fully process food waste in all directions.

[0082] In some embodiments, a plurality of convex ribs are respectively arranged on both sides in the swinging direction of the breaker 23, and the convex ribs extend from the top to the bottom of the breaker 23. For example, a plurality of convex ribs can be arranged at a position near the first end of the breaker 23, and the edges of the plurality of convex ribs are sharp, which can further crush food waste during the process of the breaker 23 hitting the food waste.

[0083] In some embodiments, vertical knives and discharge holes corresponding to the vertical knives are further arranged on the cutter head 20. Preferably, the free end of the vertical knife extends towards the inner circumferential wall of the grinding ring.

[0084] The vertical knife includes more than one first vertical knife 26 and more than one second vertical knife 27. The discharge holes include more than one first discharge hole corresponding to the first vertical knife 26 and more than one second discharge hole corresponding to the second vertical knife 27. The first vertical knife 26 protrudes from the lower surface of the cutter head 20, and the first discharge hole is located above the first vertical knife. The second vertical knife 27 protrudes from the upper surface of the cutter head 20, and the second discharge hole is located below the second vertical knife. That is, there are vertical knives above and below the cutter head 20, so as to puncture food waste above and below the cutter head 20 respectively. In some embodiments, two breakers 23 are provided, and the two breakers 23 are symmetrically arranged relative to the center of the cutter head 20; two groups of vertical knives are provided, each group includes more than one first vertical knife and more than one second vertical knife, and the two groups of vertical knives are symmetrically arranged relative to the center of the cutter head. In the circumferential direction of the cutter head 20, the vertical knives and the breakers 23 are arranged alternately, so as to form a multi-stage cutting and grinding structure in the circumferential direction on the cutter head 20.

[0085] The present invention also provides a kitchen waste processor, including: the grinding assembly described in any of the above embodiments. Specifically, the kitchen waste processor further includes: a housing and a motor disposed in the housing. The grinding assembly is disposed in the housing, and the grinding ring 10 is fixed to the housing; the driving shaft of the motor is connected to the cutter head 20 for driving the cutter head 20 to rotate relative to the grinding ring 10.

[0086] Long fiber waste enters the interior of the grinding chamber of the processor. The cutter disc 20 rotates at a high speed following the driving motor and throws the long fibers onto the inner wall of the grinding ring 10. The food thrown onto the inner wall of the grinding ring 10 can be further punctured by the first convex block 12 and the second convex block 13 on the inner wall of the grinding ring 10. At the same time, when the breaker hammer 23 is blocked by food waste such as long fibers and generates a swing or under the action of the rotational force of the cutter disc 20, it collides with the limit block on the cutter disc 20, generating a huge speed difference with the cutter disc 20, thereby impacting the fiber waste. Moreover, due to the cooperation between the first convex block 12 and the second convex block 13 on the inner wall of the grinding ring and the notch 231 and the upper surface 234 at the front end (the second end) of the grinding hammer 23 respectively, the long fiber waste is quickly sheared. At the same time, the long fibers in the gap between the grinding ring 10 and the cutter disc 20 are punctured and cut by the cutting teeth 21 around the cutter disc 20 due to the high-speed rotation of the cutter disc 20. At the same time, during the downward discharge process of the shredded long fibers through the gaps of the cutting teeth 21 of the cutter disc 20, they cooperate with the cutting knife 11 below the grinding ring 10 to cut the long fiber waste.

[0087] The present invention also provides a control method for a kitchen waste processor, which is applied to the kitchen waste processor as described above. The control method for the kitchen waste processor includes: step S11 and step S12.

[0088] In step S11, the motor rotation torque of the driving motor in the rotating state is detected.

[0089] When the driving motor is started, the driving motor rotates at an initial speed and in a first rotation direction, such as counterclockwise. During the rotation of the driving motor, the motor rotation torque is monitored in real time. Different amounts of food input into the waste processor result in different motor rotation torques. When the amount of food is large, the motor rotation torque is large; when the amount of food is small, the motor rotation torque is relatively small.

[0090] In step S12, based on the monitored motor rotation torque, the rotation speed and / or rotation direction of the driving motor are controlled.

[0091] At different rotation speeds, the impact force of the swinging of the breaker hammer is different. The amount of kitchen waste input by the user can be judged by detecting the rotation torque, and the rotation speed can be adjusted, thereby increasing or decreasing the impact force of the pendulum on the food residue. When the amount of food is large, the motor rotation torque is large, and the rotation speed of the driving motor needs to be increased. When the amount of food is small, the motor rotation torque is small, and the rotation speed of the driving motor can be reduced. By monitoring the impact force of the pendulum in real time and changing the rotation speed in real time, the balance between the breaking efficiency and the wear of the cutter disc parts can be achieved, protecting the cutter disc and the operation of the motor, reducing the failure rate.

[0092] It is also possible to judge the current cutting and grinding situation of kitchen waste by detecting the rotational torque, so as to adjust the rotational speed of the cutter head. When starting to cut at the same rotational speed of the cutter head, there is more food and greater torque. When ending the cutting, there is less food and smaller torque. When the cutter head rotates clockwise, the side part of the serrated knife cuts and discharges food residues. When the cutter head rotates counterclockwise, the side part of the serrated knife jams the fibrous food residues into the gaps of the pointed bayonets, and cooperates with the pendulum to cut off the fibers and shear the long fibers.

[0093] In some embodiments, the method further includes: step S13 and step S14;

[0094] In step S13, in response to the power-on instruction, control the drive motor to rotate in the first rotation direction for a first preset time; the drive motor rotates in the first rotation direction such as the counterclockwise direction when powered on, and rotates in the first rotation direction for, for example, 60 to 120 seconds;

[0095] In step S14, in response to the instruction indicating the end of the first preset time of the motor rotation, control the drive motor to rotate in the second rotation direction, where the second rotation direction is opposite to the first rotation direction.

[0096] After the drive motor rotates in the first rotation direction for, for example, 60 to 120 seconds and ends, the drive motor rotates in the second rotation direction, for example, rotates clockwise for a second preset time. The second preset time can be 60 to 120 seconds, and then rotates counterclockwise again. Under the control of a predetermined instruction, the motor realizes forward and reverse rotation, exerts the cutting and grinding effect, and more effectively crushes food residues. The forward and reverse rotation of the motor and the control of the speed are beneficial to protecting the motor and reducing the wear of the grinding components, and extending the service life of the key core components of the processor.

[0097] During the relative rotation of the cutter head 20 with respect to the grinding ring 10, the kitchen waste moves due to the high-speed centrifugal force of the cutter head 20. The food waste impacts the first blade 21 and / or the second blade 21 on the cutter head 20, causing the first blade 21 and / or the second blade 22 to rotate relative to the cutter head 20. Since the first blades 21 are staggered up and down, during the relative rotation of the first blade 21 and / or the second blade 22 with respect to the cutter head 20, the first cutting edge on the first blade 21 and the second cutting edge on the second blade 22 are staggered and overlapped to shear and cut the food waste such as flexible fibers. At the same time, the food waste is impacted by the reciprocating swing of the crushing hammer 25. And while the convex block 26 guides the crushing hammer 25, it is beneficial for the second cutting edge 261 at the top to perform a cutting action on the food waste. Furthermore, the food is punctured and cut by the vertical knife. Therefore, after the food is subjected to multiple treatments such as impact, shear, and puncture, the food residues are further ground and pulverized by the cooperation of the cutting teeth 201 on the cutter head 20 and the cutting piece 11, and are fully processed and then discharged after the food waste is fully processed.
