Abstract
Description
Technical Field
[0001] The invention relates to a kitchen appliance, in particular to a kitchen waste disposer. Background Art
[0002] With the promotion of garbage classification, more and more kitchen waste disposers are installed on kitchen sinks. Some kitchen waste disposers now usually use the centrifugal force generated by the high-speed rotation of the cutter disc and the combined effect of flowing water to collide the kitchen waste with the upper blade of the cutter disc to crush the garbage, and discharge it from the discharge hole on the side wall of the cutter disc cavity. The crushed kitchen waste is discharged into the sewer pipe under the push of flowing water. Since the discharge port is in the direction of the centrifugal force, the current crushing method still has a large number of strip-shaped fibers after crushing. Since most of the domestic residential sewer pipes were not designed with kitchen waste disposers in mind, the presence of a large number of long fiber garbage can easily cause sewer pipe blockage, causing unpleasant disputes between neighbors.
[0003] In addition, the existing food waste disposers will rotate to avoid the movable blade when it encounters hard bone material, which causes the two movable blades to be asymmetric, causing the overall center of gravity of the blade to shift, resulting in greater vibration and noise during operation. Summary of the invention
[0004] The purpose of the present invention is to provide a kitchen waste disposer, which changes the existing lateral discharge mode to a downward discharge mode, and reduces the size of the cutter disc to a cutter seat that is only used to connect the movable cutter head, and arranges a synchronous gear between the two cutter heads. The two cutter heads ensure that the two knives are always in a symmetrical state during operation through the synchronous gear, and have good balance during operation, so that the noise during crushing can be controlled. It has the characteristics of low noise, small vibration, fine crushed particles, and not easy to clog the sewer pipe.
[0005] To achieve the above purpose, the following technical solutions are adopted:
[0006] A kitchen waste disposer comprises: a feed inlet, a silo and a driving motor, the feed inlet is connected to an upper port of the silo, the silo is sleeved on a motor shaft of the driving motor, and is characterized in that: a material discharge baffle is arranged in the silo, the material discharge baffle divides the silo into an upper silo and a lower silo, a material discharge interface is provided on a side wall of the lower silo, an upper knife seat and a lower knife disc are respectively sleeved above and below the motor shaft located above and below the material discharge baffle, and blades are provided on the outer edge of the lower knife disc; movable cutter heads are pivotally connected on both sides of the upper knife seat, a plurality of material discharge holes penetrating the material discharge baffle up and down are provided on the material discharge baffle, a grinding gear ring is provided on the inner wall of the upper silo, and when the movable cutter head is opened, the outer edge of the movable cutter head cooperates with the inner wall of the grinding gear ring; when the movable cutter head rotates to a state of being close to the upper cutter seat, a space is left between the outer edge of the movable cutter head and the inner wall of the grinding gear ring; a material guide ring is also provided on the inner wall of the silo located above the grinding gear ring, and a plurality of material guide plates are provided on the inner wall of the material guide ring.
[0007] The angle between the shearing surface of the side of the movable cutter head and the surface of the blanking baffle is less than or equal to 90 degrees; and the bottom of the movable cutter head is in close contact with the upper surface of the blanking baffle.
[0008] The pivot position of the movable cutter head is provided with an upward conical protrusion.
[0009] A convex block is arranged in the middle of the top surface of the movable cutter head.
[0010] An inclined portion is arranged at the outer end of the shearing surface on the side of the movable cutter head.
[0011] A synchronous gear is sleeved on the motor shaft between the unloading partition plate and the upper knife seat, and teeth are arranged on the outer edge of the pivotal part of the movable knife head, and the teeth are meshed with the synchronous gear.
[0012] The bottom of the upper knife seat is provided with a receiving groove to wrap the synchronous gear inside.
[0013] The upper knife seat is in the shape of an elongated strip, and the movable knife head is in the shape of an arc. The movable knife head is pivotally connected at both ends of the length direction of the elongated upper knife seat. When the two movable knife heads are rotated to be close to the upper knife seat, the outer edges of the upper knife seat and the movable knife head are approximately circular. At this time, the distance between the outer edge of the movable knife head and the inner wall of the grinding gear ring is greater than one third of the radius of the unloading partition.
[0014] A shearing groove is also arranged on the upper surface of the blanking partition, and the shearing groove is not parallel to the radial direction of the motor shaft.
[0015] The present invention reduces the existing knife disc to an upper knife seat in the shape of an elongated strip, increases the size of the movable knife head, and provides a material discharge hole on a material discharge baffle. When working, the movable knife head and the guide plate cooperate to generate a downward thrust for the kitchen waste, and then the outer edge of the movable knife head is ground with the grinding gear ring and the shear surface of the movable knife head is cut with the surface of the material discharge baffle, so that the kitchen waste is ground and cut into fine particles and enters the lower bin. The fine particles of kitchen waste in the lower bin are discharged into the sewer through the discharge interface under the action of the blades and water flow on the lower knife disc. Since the present invention discharges downward rather than radially, there are no strip fibers in the kitchen waste after grinding and shearing, thereby effectively solving the problem of the existing kitchen waste processor that is easy to clog the sewer.

[0026] The angle between the shearing surface 61 on the side of the movable cutter head 6 and the surface of the unloading baffle 5 is less than or equal to 90 degrees; and the bottom of the movable cutter head 6 is in close contact with the upper surface of the unloading baffle 5; the movable cutter head 6 is provided with an upward conical protrusion 62 at the pivot position; a protrusion 63 is provided in the middle of the top surface of the movable cutter head 6; an inclined portion 65 is provided at the outer end of the side of the shearing surface 61 of the movable cutter head 6; the upper cutter seat 24 is in the shape of an elongated strip, and the movable cutter head 6 is in the shape of an arc, and the movable cutter head 6 is pivotally connected to the two ends of the elongated upper cutter seat 24 in the length direction. When the two movable cutter heads 6 are rotated to a state of being in close contact with the upper cutter seat 24, the outer edges of the upper cutter seat 24 and the movable cutter head 6 are approximately circular; at this time, the distance between the outer edge of the movable cutter head 6 and the inner wall of the grinding gear ring 7 is greater than one third of the radius of the unloading baffle 5.
[0027] A synchronous gear 27 is also sleeved on the motor shaft 31 between the unloading baffle 5 and the upper knife seat 24, and a tooth pattern 64 is arranged on the outer edge of the pivotal part of the movable knife head 6, and the tooth pattern 64 is meshed with the synchronous gear 27; a receiving groove is provided at the bottom of the upper knife seat 24 to wrap the synchronous gear 27 inside.
[0028] When the present invention is working, kitchen waste enters the silo 2 from the feed inlet 1, and the motor drives the upper knife seat 24 and the movable knife head 6 to rotate at a high speed. The movable knife head 6 is opened, and the kitchen waste hits the grinding gear ring 7 outwardly under the centrifugal force, and is ground between the outer edge of the movable knife head 6 and the inner wall of the grinding gear ring 7. The conical protrusion 62 and the convex block 63 on the top surface of the movable knife head 6 repeatedly hit and stir the kitchen waste. At the same time, a guide ring 8 is arranged above the grinding gear ring 7, and a plurality of guide plates 81 are arranged on the inner wall of the guide ring 8. When the movable knife head 6 drives the kitchen waste to rotate, the guide plate 81 generates a downward thrust on the kitchen waste, and pushes the kitchen waste downward to the lower material partition plate 5. Through the impact, stirring and grinding, most of the kitchen waste is removed. The kitchen waste is crushed into finer particles and can enter the lower bin through the discharge hole 51 of the discharge baffle 5. When some slender fibers enter the discharge hole 51, they are cut off by the shear surface 61 of the movable blade head and the surface of the discharge baffle 5, thereby ensuring that the kitchen waste entering the lower bin is all fine particles, and there are basically no strip fibers that are easy to clog the sewer pipe. The kitchen waste entering the lower bin is discharged through the discharge interface 23 under the action of the blades 26 and the water flow; the present invention changes the existing radial discharge into an axial discharge method, presses down through the guide plate 81, and increases the cutting between the movable blade head 6 and the surface of the discharge baffle 5, so that the crushed kitchen waste particles are smaller and will not clog the sewer pipe.
[0029] In addition, the present invention improves the existing upper knife disc into an elongated upper knife seat 24, and the movable knife head is pivotally connected to the two ends of the upper knife seat 24. When encountering larger and harder kitchen waste obstacles, the avoidance space is larger and will not cause jamming. At the same time, the two movable knife heads 6 are meshed and connected by a synchronous gear 27, so that the opening angles of the two movable knife heads 6 when rotating are synchronized, and the contraction angles when encountering obstacles are also synchronized, ensuring that the center of gravity does not shift during high-speed rotation, and it is more stable during operation, with the characteristics of light vibration and light noise.
[0030] The present invention further provides a shearing groove 52 on the upper surface of the material discharge baffle 5, and the shearing groove 52 is not parallel to the radial direction; the shearing groove 52 can cut and clean the garbage on the shearing surface of the movable cutter head 6, thereby avoiding the accumulation of adhesions between the movable cutter head 6 and the surface of the material discharge baffle 5 to affect the shearing effect.
