[0002] Dishwashers are devices that automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Modern dishwashers have a food scraper at the bottom of the inner drum to break up food scraps and drain them with the water, preventing food scraps from clogging the drain.

[0003] However, when the food residue crusher is crushing food residue, if some large residues appear and come into direct contact with the blades of the food residue crusher, the blades may not be able to cut the residues, causing the blades to jam. This not only causes other residues to enter the drainage channel and block the drainage channel, but also damages the motor that drives the blades, as the motor may be stuck in a jammed state for a long time.

The mounting opening of each mounting rib is located at the same end of itself in the circumferential direction of the crushing blade, and the positioning buckle can enter the positioning hole through the mounting opening.

[0017] In one embodiment, the baffle member has a central portion that protrudes from its circumferential edge in the direction from the pulverizing inlet to the pulverizing outlet, and the surface of the baffle member on one side of the filter chamber is an arc surface.

[0018] In one embodiment, the slag discharge module includes a water cup and a filter element. The filter element is detachably disposed inside the water cup. One end of the filter element is provided with the crushing inlet. The baffle is disposed at the opposite end of the filter element. The interior of the filter element and the water cup form the crushing space. The crushing blade is rotatably disposed on the water cup, and the crushing outlet is disposed on the water cup.

[0044] See Figure 1 , Figure 1A schematic diagram of the structure of a residue crushing device according to an embodiment of the present application is shown. The residue crushing device provided in an embodiment of the present application includes a slag discharge module 10, a crushing blade 30 and a baffle 40. The slag discharge module 10 forms a crushing space 11, and the slag discharge module 10 also includes a crushing inlet 12 and a crushing outlet, which are both connected to the crushing space 11. The crushing inlet 12 and the crushing outlet are located at opposite ends of the crushing space 11.

[0045] The crushing blade 30 is rotatably disposed in the crushing space 11. The crushing blade 30 is located between the crushing inlet 12 and the crushing outlet, so that after the wastewater containing residue is input from the crushing inlet 12, the crushing blade 30 can be turned on to rotate, so that the oversized residue is broken down into small particles by the crushing blade 30 when it passes through the crushing blade 30. The small particles will continue to move with the water flow to the crushing outlet.

[0046] In actual use, the shredder outlet is usually connected to the sewer system, and wastewater carrying small particles is discharged into the sewer through the shredder outlet. Since the larger residue has been cut into smaller pieces by the shredder blade 30, only smaller particles of residue are discharged into the sewer, thus effectively preventing residue from clogging the sewer.

[0047] A baffle 40 is disposed within the grinding space 11, dividing the grinding space 11 into a grinding chamber 13 and a filtering chamber 14. The grinding blade 30 is located within the filtering chamber 14. The grinding outlet is connected to the grinding chamber 13, and the grinding inlet 12 is connected to the filtering chamber 14. The baffle 40 has filtering holes 41, the diameter of which is smaller than that of the grinding inlet 12, and all filtering holes 41 connect the grinding chamber 13 and the filtering chamber 14.

[0048] In the aforementioned residue crushing device, when excessively large residues enter the filter chamber 14 through the crushing inlet 12, the baffle 40 filters the residues through its filter holes 41. Only residues that can pass through the filter holes 41 enter the crushing chamber 13 and are then crushed by the crushing blades 30. Larger residues remain in the filter chamber 14 and are collected for subsequent centralized processing. Compared to traditional residue crushing devices, the baffle 40 filters the residues by size, preventing excessively large residues from entering the crushing chamber 13. This prevents residues from jamming the rotation of the crushing blades 30, ensuring effective crushing and preventing damage to the motors and other drive structures that power the crushing blades 30.

[0049] In some embodiments of this application, see [reference] Figure 2 and Figure 3The baffle 40, located on one side of the filter chamber 14, is also provided with a turbulence-inducing section 42. This turbulence-inducing section 42 agitates the water flow passing through the baffle 40, creating irregular turbulence as the water passes through it. In actual use, because the shape of the residue is irregular, some residues may be large enough to enter the filter holes 41, but due to incorrect angles, they may not be able to enter. The irregular turbulence created by the turbulence-inducing section 42 allows the residues to attempt to enter the filter holes 41 at different angles, thus allowing more residues to enter the pulverizing chamber 13 and preventing residues from accumulating at the baffle 40 and clogging the filter holes 41.

[0050] In some embodiments, the surface of the baffle member 40 on one side of the filter chamber 14 is recessed towards the pulverizing chamber 13 to form a turbulence-disrupting portion 42. That is, the baffle member 40 has irregular recesses on its surface, which disturb the water flow passing through the baffle member 40. In other embodiments, the turbulence-disrupting portion 42 may also protrude from the surface of the baffle member 40 on one side of the filter chamber 14, thereby disturbing the water flow passing through the baffle member 40 through the protruding turbulence-disrupting portion 42.

[0051] It is understandable that the flow disturbance part 42 can be selected in any shape according to actual usage requirements, as long as it can disturb the water flow, and there is no limitation here.

[0052] In some specific embodiments, the filter holes 41 include multiple holes, and all the filter holes 41 are arranged at intervals, so that when the residue is subjected to the action of water flow, it can enter the crushing chamber 13 through different filter holes 41 and be crushed by the crushing blade 30, thereby increasing the probability of the residue entering the crushing chamber 13 and further preventing the residue from accumulating at the baffle 40 and clogging the filter holes 41.

[0053] Furthermore, the flow-dispersing section 42 includes two parts, both located at the edge of the baffle member 40. The filter holes 41 include multiple parts, comprising two sets, with each set located on opposite sides of the line connecting the two flow-dispersing sections 42. Specifically, the pulverizing space 11 has a cylindrical structure, the baffle member 40 has a circular structure, the two flow-dispersing sections 42 are located at both ends of the baffle member 40's diameter, and the diameter serves as a dividing line. Two sets of filter holes 41 are located on either side of this dividing line, with each set including multiple filter holes 41.

[0054] Thus, after the water flow is disturbed by the turbulence section 42 located on the edge of the baffle 40, the water flow carrying the residue will move towards the center of the baffle 40, thereby entering the multiple filter holes 41 located in the center of the turbulence section 42, and finally entering the pulverizing chamber 13 to be pulverized.

[0055] In some embodiments of this application, the edge of the baffle 40 is provided with a plurality of positioning buckles 43, all of which are spaced around the circumference of the baffle 40. Each positioning buckle 43 can be engaged with the slag discharge module 10. The engagement method facilitates the installation of the baffle 40 into the crushing space 11.

[0056] Specifically, see Figure 5 The slag discharge module 10 has multiple positioning holes 15, all of which are arranged around the circumference of the crushing blade 30. Each positioning buckle 43 corresponds to one of the positioning holes 15, and each positioning buckle 43 can be inserted into the positioning hole 15. In actual use, the baffle 40 can be made of a plastic part with a certain degree of elasticity. Through the deformation of the plastic part, each positioning buckle 43 can be aligned with each positioning hole 15. After the plastic part returns to its original shape, each positioning buckle 43 of the baffle 40 can be inserted into the positioning hole 15.

[0057] Specifically Figure 1 In one embodiment, the baffle 40 can also be installed by rotation. Specifically, the slag discharge module 10 is provided with multiple mounting ribs 16. All mounting ribs 16 are located on the inner wall of the crushing space 11 and are arranged around the circumference of the crushing blade 30. Each mounting rib 16 has a positioning hole 15 on the side facing the crushing blade 30. Along the circumferential direction of the crushing blade 30, the positioning hole 15 extends to the end face of one end of the mounting rib 16 and forms a mounting opening 17. The mounting opening 17 of each mounting rib 16 is located at the same end of itself in the circumferential direction of the crushing blade 30. The positioning buckle 43 can enter the positioning hole 15 through the mounting opening 17.

[0058] In actual use, the width between the two mounting ribs 16 is greater than the gap of the positioning buckles 43. First, place each positioning buckle 43 between the two mounting ribs 16. Then, rotate the baffle 40 so that each positioning buckle 43 can enter the mounting opening 17 of each mounting rib 16. Continue to rotate the baffle 40 so that the positioning buckles 43 can enter the positioning holes 15. Finally, the installation of the baffle 40 is completed. Optionally, there are four positioning buckles 43 and four mounting ribs 16.

[0059] In some embodiments of this application, the baffle member 40 has a central portion that protrudes from its circumferential edge in the direction from the crushing inlet 12 to the crushing outlet, and the surface of the baffle member 40 on one side of the filter chamber 14 is arc-shaped. Specifically, the baffle member 40 includes a baffle body 44 and a plurality of positioning buckles 43 disposed circumferentially on the baffle body 44. The positioning buckles 43 are inclined relative to the baffle body 44, so that when the positioning buckles 43 are disposed on the mounting rib 16, the baffle body 44 has a certain height difference relative to the mounting rib 16, thereby causing the baffle body 44 to protrude relative to the positioning buckles 43. Furthermore, the surface of the baffle body 44 is arc-shaped, thereby forming a spherical structure on one side of the baffle body 44.

[0060] The baffle body 44 is provided with filter holes 41. The protruding design of the baffle body 44 ensures that residue first contacts the filter holes 41. Smaller residues directly enter the crushing chamber 13 through the filter holes 41, while larger residues are caught by the baffle 40. Strip-shaped residues, under the action of the curved surface of the baffle body 44, flow along the baffle body 44 into the gap between the two positioning buckles 43, and finally enter the crushing chamber 13 through the gap, where they are crushed by the crushing blade 30. In this way, the curved surface of the baffle 40 guides some strip-shaped residues, allowing them to enter the crushing chamber 13 for crushing, preventing them from accumulating at the baffle 40 and clogging the filter holes 41.

[0061] In some embodiments of this application, see [reference] Figure 1 and Figure 5 The slag discharge module 10 includes a water cup component 20 and a filter component 21. The filter component 21 is detachably disposed inside the water cup component 20. One end of the filter component 21 is provided with a crushing inlet 12, and a baffle component 40 is disposed at the opposite end of the filter component 21. The interior of the filter component 21 and the water cup component 20 form a crushing space 11. The crushing blade 30 is rotatably disposed on the water cup component 20, and the crushing outlet is disposed on the water cup component 20.

[0062] Thus, after the baffle 40 divides the pulverizing space 11 into a filter chamber 14 and a pulverizing chamber 13, the entire space in the filter chamber 14 will be located on the filter element 21, causing larger particles filtered by the baffle 40 to remain inside the filter element 21. Afterwards, the user can remove the filter element 21 from the water cup 20 to clean the remaining particles in the filter chamber 14 separately, preventing excessive particles from affecting drainage.

[0063] In some embodiments, the circumferential sidewall of the filter element 21 and the water cup 20 enclose a filtration space 22. The water cup 20 also includes a return water inlet communicating with the filtration space 22. A first filter screen 23 is provided on the circumferential sidewall of the filter element 21, and the filtration space 22 and the pulverizing space 11 are connected via the first filter screen 23. Specifically, the bottom of the water cup has a step, which abuts against the bottom of the filter element 21, so that the bottom of the water cup and the bottom of the filter element 21 are connected to form the pulverizing space 11. The inner wall of the water cup and the outer wall of the filter element 21 enclose the filtration space 22.

[0064] When a food waste disposal unit is used in a dishwasher, a water recycling system is often employed to conserve water. Therefore, wastewater generated during the first wash passes through the food waste disposal unit and enters the disposal chamber 11 through the disposal inlet 12. The return outlet is connected to the dishwasher's return pump. During return, the disposal outlet is disconnected from the external drain. This disconnection can be achieved by closing the disposal outlet or by shutting down the drain pump connected to the disposal outlet. During return, the return pump creates suction at the return outlet, which acts on the filter chamber 22 and the disposal chamber 11, causing water from the disposal chamber 11 to flow into the return outlet. During this process, the water flows through the first filter screen 23, trapping food waste in the filter element 21, allowing only water to pass through. The food waste is then discharged during the next drain cycle.

[0065] Specifically, in some embodiments, see [link to relevant documentation]. Figure 5 The filter element 21 includes a first filter section 24, a second filter section 25, and a planar filter section 26. The first filter section 24 is located inside the water cup, while the second filter section 25 and the planar filter section 26 are both located outside the water cup. The first filter section 24 is arranged around the circumference of the pulverizer 30 and forms a filter space 22 with the water cup 20. A first filter screen 23 is provided on the circumferential side wall of the first filter section 24. A pulverizing inlet 12 is provided at the end of the second filter section 25 away from the water cup. A second filter screen 27 is provided on the circumferential side wall of the second filter section 25, and the second filter screen 27 connects the outside of the second filter section 25 with the pulverizing space 11.

[0066] The planar filter section 26 is located between the first filter section 24 and the second filter section 25, and has a guide surface 28 arranged around the second filter section 25. The guide surface 28 is inclined, and when the residue crushing device is in use, the first filter section 24 is located at the lowest point of the guide surface 28 in the direction of gravity.

[0067] Thus, the water flow, after passing through the planar filter section 26, is guided to the second filter section 25 by the flow guide surface 28. A portion of the water flows directly through the second filter screen 27 into the pulverizing space 11, where the residue is filtered by the first filter screen 23 and remains on the surface of the planar filter section 26. The remaining water flows through the pulverizing inlet 12 into the pulverizing space 11, and then passes through the first filter screen 23, leaving residue inside the filter element 21. When cleaning the filter element 21, the user can clean both the residue on the surface of the planar filter section 26 and the residue inside the filter element 21.

[0068] In some embodiments of this application, see [reference] Figure 1 and Figure 4 The pulverizer 30 includes a blade shaft 31 and multiple blades 32 mounted on the blade shaft 31. A drive unit 50, which can be a motor, is also located at the bottom of the water cup. The output shaft of the drive unit 50 is connected to the blade shaft 31, allowing the drive unit 50 to drive the blade shaft 31 and the blades 32 to rotate. Furthermore, a sealing ring 33 is also provided at the bottom of the water cup, surrounding the drive shaft 51. The sealing ring 33 prevents water from flowing into the pulverizing chamber 13 and damaging the drive unit 50.

[0069] This application also provides a kitchen appliance, including a food waste pulverizing device as described in any of the above embodiments. This kitchen appliance can be directly used for pulverizing food waste, such as a food waste disposer installed under a sink, or a dishwasher. Specifically, when the kitchen appliance is a dishwasher, the dishwasher has a washing chamber for washing dishes, and the washing chamber is connected to the pulverizing inlet 12 so that water flow can carry the food waste into the food waste pulverizing device, where it is pulverized and discharged into the sewer.

[0070] The above-mentioned residue crushing device has at least the following advantages:

[0071] When excessively large residues enter the filter chamber 14 through the crushing inlet 12, the baffle 40 filters them through its filter holes 41. Only residues that can pass through the filter holes 41 enter the crushing chamber 13 and are then crushed by the crushing blades 30. Larger residues remain in the filter chamber 14 and are collected for subsequent centralized processing. Compared to traditional residue crushing devices, the baffle 40 filters the residues by size, preventing excessively large residues from entering the crushing chamber 13. This prevents residues from jamming the rotation of the crushing blades 30, ensuring effective crushing and preventing damage to the motors and other drive structures that power the crushing blades 30.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
