Description

Technical Field

[0001] This application relates to the technical field of kitchen waste treatment, and particularly to a kitchen waste processor. Background Art

[0002] A kitchen waste processor is used to crush and grind kitchen waste, grind kitchen waste including leftovers, rice, vegetable leaves, fruit peels, fish bones, vegetable stalks, eggshells, tea dregs, bones, shells, etc. into fine particles, and then discharge them into the drainage pipe. A kitchen waste processor usually includes an anti-corrosion grinding cavity, a grinding disc and grinding hammers, etc. The grinding disc and grinding hammers are driven by a motor to rotate, and the kitchen waste is crushed in the grinding cavity and then discharged.

[0003] The processing capabilities of existing kitchen waste processors vary. If the kitchen waste particles to be processed are relatively large, it may exceed the bearing capacity of the drainage pipe, thereby blocking the drainage pipe. In the prior art, in order to reduce the size of the crushed kitchen waste

[0004] usually a multi-stage grinding method is used, which has a complex structure and high cost. Moreover, due to installation errors or machining dimensions, etc., it is still difficult to ensure that the fineness of the ground particles can fully meet the requirements, and the particle sizes are uneven, posing a high risk of blocking the pipeline. Once the pipeline is blocked, the maintenance will be very troublesome and will affect normal life. Summary of the Invention

[0005] In view of the deficiencies in the above technologies, this application provides a kitchen waste processor that can better prevent the crushed kitchen waste from blocking the pipeline.

[0006] To solve the above technical problems, the technical solution adopted in this application is: A kitchen waste processor, comprising:

[0007] A housing, in which an installation ring body is provided;

[0008] A grinding assembly, the grinding assembly includes a grinding disc driven by a motor to crush kitchen waste, and the grinding disc is provided with a return hole for large-particle kitchen waste to pass through;

[0009] A filter disc, the filter disc is connected to the installation ring body, and is provided with a plurality of filter holes for small-particle kitchen waste to pass through; the kitchen waste crushed by the grinding assembly passes through the filter disc for filtration; and

[0010] A stirring member, the stirring member is driven by the motor to rotate, and is used to stir the kitchen waste on the filter disc to flow back to the grinding assembly through the return hole.

[0011] Further, the reflux hole is in the shape of a tapered hole with a smaller upper part and a larger lower part, which is convenient for guiding the kitchen waste located below the grinding disc to pass through the reflux hole from bottom to top.

[0012] Further, the kitchen waste processor further includes a one-way guide sleeve disposed in the reflux hole, and the one-way guide sleeve enables large-particle kitchen waste below the grinding disc to pass through the grinding disc unidirectionally from bottom to top.

[0013] Further, the one-way guide sleeve is in the shape of a tapered ring, and it includes an upper opening, a lower opening larger than the upper opening, and a deformation groove penetrating the upper opening and the lower opening. The one-way guide sleeve is made of an elastic material.

[0014] Further, the grinding disc is provided with a concave hole communicating with the reflux hole, and the upper end of the one-way guide sleeve extends into the concave hole.

[0015] Further, the stirring member is located between the grinding assembly and the filter disc, and it includes blades for stirring water flow.

[0016] Further, the blades are arranged to drive the water flow downward when rotating forward and drive the water flow upward when rotating in reverse.

[0017] Further, a plurality of first diversion holes are provided in the mounting ring body above the grinding assembly, and the large-particle kitchen waste cannot pass through the first diversion holes.

[0018] Further, the kitchen waste processor further includes a mounting bottom plate connected between the mounting ring body and the inner wall of the housing, and a plurality of second diversion holes are provided in the mounting bottom plate.

[0019] Further, the housing is provided with a connection port connected to a drainage pipe, and a water valve is provided on the connection port.

[0020] Compared with the prior art, the beneficial effects of this application are as follows:

[0021] 1. The kitchen waste processor of this application is provided with a grinding assembly, a filter disc and a stirring member in the housing. The filter disc only allows small-particle kitchen waste to pass through. Therefore, the large-particle kitchen waste that is not completely ground by the grinding assembly will be blocked by the filter disc, and under the agitation of the stirring member, it will return to the grinding assembly through the grinding disc for re-grinding, thereby effectively improving the fineness of the ground kitchen waste and reducing the risk of the kitchen waste blocking the drainage pipe. At the same time, the kitchen waste processor of this application has a simple structure and low cost;

[0022] 2. The food waste processor of the present application is provided with a one-way guide sleeve in the grinding disc. Large-particle food waste can only pass through the one-way guide sleeve unidirectionally from bottom to top, and cannot pass through from top to bottom, which can prevent large-particle food waste from moving back and forth on the grinding disc and improve the grinding efficiency.

[0023] 3. In the present application, when the rotation direction of the motor is different, the stirring member can drive the water flow to move in different directions. When driving the water flow to move downward, it can drive small-particle food waste to pass through the filter disc faster; when driving the water flow to move upward, it can drive large-particle food waste to pass through the one-way guide sleeve faster, thereby improving the working efficiency.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products, or devices.

[0034] Referring to "embodiments" in this context means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The occurrence of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] As Figure 1 shown, corresponding to an anti-clogging kitchen waste processor according to a preferred embodiment of the present application, it includes a main body 1 and a sink connection assembly 2 connected to the upper end of the main body 1. The sink connection assembly 2 is used to connect to the sink drain outlet, so that the kitchen waste in the sink can be flushed into the main body 1 along with the water flow.

[0036] The main body 1 includes an outer shell 10 and an inner shell 11. The inner shell 11 can be an independent part installed inside the outer shell 10 or integrally formed with the outer shell 10. The inner shell 11 includes an annular mounting ring body 110 and a mounting bottom plate 111 connected to the bottom of the mounting ring body 110. The upper end of the mounting ring body 110 is connected to the inner wall of the upper end of the outer shell 10, and the outer periphery of the mounting bottom plate 111 is connected to the inner wall of the outer shell 10, so that the inner shell 11 isolates the inside of the outer shell 10 into a crushing chamber 12 and a reflux chamber 13, where the crushing chamber 12 is located inside the inner shell 11, and the reflux chamber 13 is located between the outside of the inner shell 11 and the outer shell 10.

[0037] The main body 1 further includes a grinding assembly 3, a filter disk 4, and a stirring member 5 all installed in the crushing chamber 12.

[0038] The housing 10 is usually assembled from a plurality of shells to facilitate installation of the grinding assembly 3 and other components in the housing 10. The grinding assembly 3 is driven by a motor, which is installed near the lower end of the housing 10, and the rotating shaft 30 of the motor extends upward through the filter plate 4 and is connected to the grinding assembly 3 and the agitator 5, and can drive the grinding assembly 3 and the agitator 5 to work.

[0039] The housing 10 is provided with a connection port 100 for connecting to a drainage pipe, and the connection port 100 is communicated with the interior of the housing 10, and the crushed small particles of food waste will be discharged into the drainage pipe through the connection port 100. The connection port 100 is provided with a water valve 101, and the water valve 101 is used to open or close the connection port 100. The water valve 101 can be a manually opened and closed faucet or an electric valve, preferably an electric valve, which is electrically connected to the control system of the food waste disposer and is controlled by the control system.

[0040] The grinding assembly 3 includes a grinding ring 31 fixed on the inner wall of the mounting ring body 110 and a grinding disc 32 disposed in the grinding ring 31. The grinding disc 32 is connected to the rotating shaft 30 of the motor and is driven to rotate by the motor. Figure 2 As shown, the grinding ring 31 includes a ring body 310 and a convex ring 311 disposed on the upper end of the ring body 310 and convex outward, and the convex ring 311 is connected to the mounting ring body 110, so that there is a gap 312 between the ring body 310 and the mounting ring body 110. A plurality of through holes 3100 are disposed on the peripheral wall of the ring body 310, and a grinding hammer 33 and a tearing device and other components are disposed on the grinding disc 32. The tearing device is used to tear the kitchen waste and stir the water flow to make the kitchen waste thrown to the inner peripheral wall of the grinding ring 31. The kitchen waste on the inner peripheral wall will be embedded in the through hole 3100 and cut off under the cooperation of the grinding hammer 32 and the grinding ring 31, and then the cut kitchen waste located in the through hole 3100 will be separated from the grinding ring 31 through the gap 312.

[0041] A protruding static toothed disc 313 is provided at the lower end of the ring body 310, and a movable toothed disc 320 is provided at the lower end of the grinding disc 32. The movable toothed disc 320 is located below the static toothed disc 313 and can rotate with the rotation of the grinding disc 32. Cutting teeth are provided on the outer periphery of the movable toothed disc 320 and the static toothed disc 313 and are located below the gap 312. During the relative rotation process, the kitchen waste leaking from the static toothed disc 313 will be continuously ground into smaller particles of kitchen waste.

[0042] The filter plate 4 is located below the grinding assembly 3 and is used to filter the kitchen waste according to its size. In the present application, the kitchen waste that can pass through the filter plate 4 is called small-particle kitchen waste, which has little or no risk of clogging the drainage pipe, while the kitchen waste that cannot pass through the filter plate 4 is called large-particle kitchen waste, which has a greater risk of clogging the drainage pipe. The filter plate 4 is connected to the inside of the mounting ring body 110, and its peripheral wall is matched with the inner surface of the mounting ring body 110, such asFigure 3 As shown, a plurality of filter holes 40 are formed in the filter disc 4. The size of the filter holes 40 is adapted to the size of the small particle kitchen waste, and it can also be slightly larger than the small particle kitchen waste to facilitate the passage of the small particle kitchen waste. The kitchen waste pulverized by the grinding assembly 3 can only enter the drainage pipe downward after passing through the filter disc 4. Therefore, only the small particle kitchen waste can enter the drainage pipe, and the large particle kitchen waste will remain on the filter disc 4, greatly reducing the risk of blocking the drainage pipe.

[0043] Continue to refer to Figure 1 , the stirring member 5 is installed on the rotating shaft 30 of the motor and is located between the grinding assembly 3 and the filter disc 4. Its function is to return the large particle kitchen waste that cannot pass through the filter disc 4 to the upper end of the grinding assembly 3 for grinding again. The stirring member 5 includes a connecting sleeve 50 connected to the rotating shaft 30 and a plurality of blades 51 provided on the connecting sleeve 50. After the rotating shaft 30 rotates, it will drive the blades 51 to rotate, thereby stirring the water flow to move the large particle kitchen waste above the grinding disc 32.

[0044] As Figure 2 shown, a return hole 321 is provided on the grinding disc 32. The return hole 321 communicates the upper and lower parts of the grinding disc 32, so that the large particle kitchen waste can pass through the return hole 321 from bottom to top and enter above the grinding disc 32. In one embodiment, the return hole 321 is a circular hole, and its size is adapted to the size of the large particle kitchen waste, enabling the large particle kitchen waste to pass through; in another embodiment, as Figure 4 shown, the return hole 321 is in the shape of a tapered hole with a smaller upper part and a larger lower part. Its upper end opening can enable the large particle kitchen waste to pass through. Due to its tapered hole shape, after the water flow is stirred, the large particle kitchen waste below will more conveniently pass through the return hole 321; preferably, the size of the upper end opening of the return hole 321 is 1.1 - 1.5 times the diameter of the filter hole 40.

[0045] Furthermore, in order to prevent the large particle kitchen waste above the grinding disc 32 from directly entering below the grinding disc 32 through the return hole 321 and improve the efficiency of re-grinding, a one-way guide sleeve 322 is also provided in the return hole 321. As Figure 5 and Figure 6As shown, the one-way guide sleeve 322 is in the shape of a cone ring as a whole, and is provided with an upper opening 3220 whose size is smaller than or equal to that of small-particle kitchen waste and a lower opening 3221 of a larger size, and the size of the lower opening 3221 is at least larger than that of large-particle kitchen waste. The one-way guide sleeve 322 is also provided with a deformation groove 3223 running through its upper and lower ends. The one-way guide sleeve 322 is made of an elastic material such as a thin steel sheet, a rubber sheet, etc., and can be elastically deformed when subjected to pressure, so that the size of the upper opening 3220 becomes larger or smaller. When the stirred water flows through the one-way guide sleeve 322 from bottom to top, the water flow inside it will drive the one-way guide sleeve 322 to open, thereby expanding the upper opening, so that large particles of food waste can pass through the one-way guide sleeve 322 from bottom to top; conversely, when the water flows through the one-way guide sleeve 322 from top to bottom, the water flow will squeeze the outer wall of the one-way guide sleeve 322, so that the size of the upper opening 3220 becomes smaller, so that the food waste above cannot move from the one-way guide sleeve 322 to the bottom, and can only enter the bottom of the grinding component 3 after grinding, ensuring that the large particles of food waste can be ground again, thereby improving the grinding effect.

[0046] Preferably, the size of the one-way guide sleeve 322 is slightly smaller than that of the return hole 321 to facilitate the size change thereof.

[0047] like Figure 5 As shown, a limiting boss 3210 protruding inward is provided below the reflux hole 321 to limit the position of the one-way guide sleeve 322. A concave hole 323 communicating with the reflux hole 321 is provided at the upper end of the grinding disc 32. The upper end of the one-way guide sleeve 322 extends into the concave hole 323, which can facilitate the water flow from top to bottom to squeeze the outer wall of the one-way guide sleeve 322, thereby reducing the size of the upper opening 3220.

[0048] In the present application, during normal grinding operation, the rotation direction of the rotating shaft 30 is defined as forward rotation, and the direction opposite to the rotation direction is defined as reverse rotation. Further, the paddle 51 is configured such that: during forward rotation, the paddle 51 drives the water flow to move from top to bottom, and during reverse rotation, the paddle 51 drives the water flow to move from bottom to top.

[0049] The advantage of such a setting is that the water flow in the grinding chamber 12 can be made more directional. During the normal grinding process, the disturbance of the water flow is complex, but the paddle blade 51 rotating in the forward direction can give the water flow a downward flow force, so that it can squeeze the one-way guide sleeve 322 to reduce the upper opening 3220, preventing the kitchen waste above from directly passing through the one-way guide sleeve 322, and at the same time, small particles of kitchen waste can pass through the filter plate 4 more quickly and be discharged from the connecting port 100; and when large particles of kitchen waste need to be ground again, the motor rotates in the reverse direction, and the water flow pushes the upper opening 3220 of the one-way guide sleeve 322 upward, so that large particles of kitchen waste can pass directly through the one-way guide sleeve 322, thereby improving work efficiency.

[0050] It can be understood that when it is necessary to return large particulate kitchen waste to the grinding assembly 3, sufficient water is required in the crushing chamber 12 to drive the large particulate kitchen waste to move above the grinding assembly 3. Generally, the liquid level in the crushing chamber 12 should be higher than the grinding assembly 3. When it is necessary to increase the liquid level, only need to close the water valve 101 and add water into the crushing chamber 12. A liquid level sensor is arranged in the housing 10, which can detect whether the liquid level meets the requirements. When it does not meet the requirements, the control system can remind the user by means of sound and light, etc. It can be understood that the control of the liquid level height can be carried out by the cooperation of the faucet above the sink and the water valve 101. When both the faucet and the water valve 101 are electrically controlled, the control system can automatically control the opening and closing of the faucet and the water valve 101, so as to automatically adjust the liquid level; of course, an additional water inlet can also be arranged on the main body 1 and the water inlet can be controlled by an electric valve, so as to automatically adjust the liquid level by controlling the opening and closing of the electric valve and the water valve 101.

[0051] To make the fluidity of the water better, as Figure 2 shown, a number of first diversion holes 112 are opened at a position on the mounting ring body 110 above the grinding ring 31. The size of the first diversion holes 112 is the same as that of the filtering holes 40, and only small particulate kitchen waste can pass through. As Figure 7 shown, a number of second diversion holes 113 are opened on the mounting bottom plate 111. Due to the filtering of the first diversion holes 112 and the filtering holes 40, the kitchen waste that can pass through the second diversion holes 113 are all small particulate kitchen waste. Therefore, the size of the second diversion holes 113 is not limited. Such a structural setting makes the water flow upward through the grinding disc 32 when the paddle 51 rotates reversely, and then returns to the bottom after passing through the first diversion holes 112 and the second diversion holes 113 in sequence, with better directivity.

[0052] When the kitchen waste processor of the present application is working, forward rotation and reverse rotation can be alternated to make the grinding of kitchen waste more sufficient and complete, and reduce the risk of blocking the drainage pipeline.

[0053] The kitchen waste processor of the present application has at least the following advantages:

[0054] 1. The kitchen waste processor of the present application is provided with a grinding assembly, a filtering disc and a stirring member in the housing. The filtering disc only allows small particulate kitchen waste to pass through. Therefore, the large particulate kitchen waste that is not completely ground by the grinding assembly will be blocked by the filtering disc and, under the stirring of the stirring member, return to the grinding assembly through the grinding disc for re-grinding, thereby effectively improving the fineness of the ground kitchen waste and reducing the risk of the kitchen waste blocking the drainage pipeline. At the same time, the kitchen waste processor of the present application has a simple structure and low cost;

[0055] 2. The food waste processor of the present application is provided with a one-way guide sleeve in the grinding disc. Large particle food waste can only pass through the one-way guide sleeve unidirectionally from bottom to top, and cannot pass through from top to bottom, which can prevent large particle food waste from moving back and forth on the grinding disc and improve the grinding efficiency.

[0056] 3. The stirring member of the present application can drive the water flow to move in different directions when the rotation direction of the motor is different. When driving the water flow to move downward, it can drive small particle food waste to pass through the filter disc faster; when driving the water flow to move upward, it can drive large particle food waste to pass through the one-way guide sleeve faster, thereby improving the working efficiency.

[0057] The above is only the implementation mode of the present application, and does not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent flow made by using the specification and drawings of the present application.
