Moreover, the present application provides examples of various specific processes and materials. However, one of ordinary skill in the art will readily recognize that other processes and / or materials can be used.

[0039] The filter assembly 100 according to the first aspect of the present application is described in detail below with reference to FIGS. 1-5.

[0040] The filter assembly 100 according to the first aspect of the present application is used in a dishwasher, for example, the dishwasher can be used in a sink dishwasher, a cleaning machine or a general dishwasher.

[0041] As shown in FIGS. 1, 2, 3 and 5, the filter assembly 100 comprises a water cup (not shown in the drawings), a filter support 30 and a cylindrical filter part 20.

[0042] Specifically, the filter support 30 is installed in the water cup, the lower end of the filter support 30 is provided with a shaft hole 33, the cylindrical filter part 20 is rotatably arranged in the filter support 30, the cylindrical filter part 20 defines a filter cavity 21 with an open upper end, the cylindrical filter part 20 comprises a rotating body 22 and a rotating shaft 23, the upper end of the rotating shaft 23 is fixedly connected with the lower end of the rotating body 22 and located outside the filter cavity 21, and the lower end of the rotating shaft 23 is matched with the shaft hole 33.

[0043] It can be understood by those skilled in the art that the filter screen cover of the cylindrical filter part 20 is arranged on the rotating body 22, the filter support 30 is connected to the dishwasher, and the rotating shaft 23 matched with the shaft hole 33 can realize the rotatable connection of the rotating body 22 and the filter support 30.

[0044] During the operation of the dishwasher, in the stage of washing the tableware, the water flow will circulate and wash the tableware, the residues on the tableware will enter the filter cavity 21 together with the water flow through the opening of the filter cavity 21, and then the filter screen of the cylindrical filter part 20 filters the water flow, the filtered water flow enters the water cup, and the dishwasher washing pump continues to wash the tableware by drawing the water in the water cup.

[0045] Among them, by setting the filter assembly 100, the residues in the water flow can be filtered, the residues in the water circulating and washing the tableware are less, the cleaning function of the dishwasher can be realized, and the cleaning effect of the dishwasher is improved.

[0046] The rotating shaft 23 is connected to the lower end of the rotating body 22 and located outside the filter cavity 21, so that the rotating shaft 23 does not occupy the space in the filter cavity 21, the volume of the filter cavity 21 can be larger, so that the filtering area in the filter cavity 21 is larger, the filtering efficiency of the filter assembly 100 is improved, and when the lifting cup 40 is arranged in the filter cavity 21, the size of the lifting cup 40 arranged in the filter cavity 21 can be larger, the lifting cup 40 can accommodate more residues, and the user can reduce the frequency of cleaning the lifting cup 40 during use, thereby further improving the user experience.

[0047] Meanwhile, the rotating shaft 23 connected to the lower end of the rotating body 22 can make the center of gravity of the cylindrical filter part 20 lower, the cylindrical filter part 20 will be more stable when impacted by the water flow, the shaft hole 33 is arranged at the lower end of the filter support 30, and the ball bearing 70 arranged in the shaft hole 33 is also located at the lower end of the filter support 30, so that the center of gravity of the filter assembly 100 can be lowered, thereby improving the stability of the filter assembly 100 during operation.

[0048] It can be understood that when the food residues are on the filter assembly 100 for a long time, bacteria are easy to breed on the filter assembly 100, and the user often cleans the filter assembly 100 after use of the dishwasher, and the user also cleans the filter assembly 100 when the food residues in the filter assembly 100 are more.

[0049] When the user cleans the filter screen of the cylindrical filter part 20, the user first takes out the large-size residues in the filter cavity 21, wherein the user can directly take out the residues in the filter cavity 21, or the user can set a lifting cup 40 in the filter cavity 21 to filter the large-size residues, and when cleaning, the lifting cup 40 is taken out and the large-size residues are poured out, which can improve the cleaning efficiency and reduce the operation difficulty.

[0050] The smaller-size residues remaining on the filter screen can be washed away from the filter screen by the water flow, and in the process of washing the cylindrical filter part 20, the rotating body 22 can rotate relative to the filter support 30 under the impact of the water flow, so that the user can more easily clean each part of the cylindrical filter part 20, and the rotating body 22 can generate a centrifugal force on the residues on the filter screen during rotation, so that the residues are more easily separated from the filter screen.

[0051] The user can open the dishwasher to wash the cylindrical filter part 20 with an external water flow, or a water pump and a nozzle can be arranged in the dishwasher to clean the cylindrical filter part 20 with the water flow in the dishwasher, so as to realize self-cleaning of the dishwasher and improve the user experience.

[0052] According to the filter assembly 100 of the first aspect of the present application, on the one hand, the rotating shaft 23 does not occupy the space of the filter cavity 21, so that the filtering area in the filter cavity 21 is larger, and the filtering efficiency of the filter assembly 100 is improved, and on the other hand, the gravity center of the filter assembly 100 is lowered, so that the stability of the filter assembly 100 during operation is improved.

[0053] In some embodiments of the present application, as shown in FIGS. 2-4, the rotating body 22 includes a connecting plate part 24, the connecting plate part 24 is located at the lower end of the rotating body 22, the peripheral side of the connecting plate part 24 is provided with a plurality of water passing holes 25, for example, the water passing holes 25 can be two, three or four, and the upper end of the rotating shaft 23 is connected to the lower side surface of the connecting plate part 24.

[0054] The connecting plate part 24 can increase the connection area of the rotating shaft 23 and the rotating body 22, and it is easier to make the connection strength of the rotating shaft 23 and the rotating body 22 meet the use needs in product design.

[0055] The water flow can flow out from the lower end of the cylindrical filter component 20 through the water flow hole 25, thereby ensuring the filtering efficiency of the cylindrical filter component 20. During the product design process, the size of the connecting plate part 24, the size of the water flow hole 25, or the number of the water flow hole 25 can be adjusted to meet more product design needs.

[0056] In some embodiments of the present application, as shown in FIGS. 2 and 3, the connecting plate part 24 is opposite to the shaft hole 33 in the up-down direction, and the connecting plate part 24 blocks at least part of the shaft hole 33 in the up-down direction. It can be understood that the cylindrical filter component 20 cannot completely filter food residues in the water flow, and when the cylindrical filter component 20 is cleaned, the water flow will flush away the residues of the filter screen. The shaft hole 33 is provided with a ball bearing 70, and the connecting plate part 24 provides shielding for the shaft hole 33 in the up-down direction, which can reduce the probability of water flow and residues entering the shaft hole 33, thereby reducing the probability of residues blocking the shaft hole 33 and the ball bearing 70 in the shaft hole 33, and improving the reliability of the filtering assembly 100.

[0057] In some embodiments of the present application, as shown in FIG. 2, the connecting plate part 24 is located in the middle of the cylindrical filter component 20, the cylindrical filter component 20 is a cylinder, and the axis of the rotating shaft 23 coincides with the rotation axis of the cylindrical filter component 20. In this way, the rotation of the cylindrical filter component 20 can be more stable, the reliability of the cylindrical filter component 20 on the filtering support 30 during the operation of the filtering assembly 100 can be improved, and the noise generated during the rotation of the cylindrical filter component 20 can be reduced, further improving the user experience.

[0058] In some embodiments of the present application, as shown in FIGS. 3 and 4, the bottom of the rotating body 22 is provided with an annular support rib 221 and a plurality of connecting ribs 222, for example, the connecting rib 222 can be two, three or four, the connecting plate part 24 is located on the radially inner side of the support rib 221, one end of the connecting rib 222 is connected with the support rib 221, and the other end of the connecting rib 222 is connected with the connecting plate part 24.

[0059] In this way, the two connecting ribs 222 and the connecting plate part 24 cooperated can define the water flow hole 25, and the size of the water flow hole 25 is larger. It can be understood that the rotating body 22 and the filter screen are both low-density materials, and the force of the cylindrical filter component 20 on the rotating shaft 23 is also small during the operation of the filtering assembly 100. By connecting the plurality of connecting ribs 222 with the connecting plate part 24, the connection strength of the connecting rib 222 and the connecting plate part 24 can meet the use needs.

[0060] During the product design process, the size, shape or size of the support rib 221 of the connecting rib 222 and other parameters can be adjusted to meet more product design needs.

[0061] In some embodiments of the present application, as shown in FIGS. 2-4, the connecting rib 222 comprises an inclined section 2221 and a horizontal section 2222, the inclined section 2221 is connected between the horizontal section 2222 and the support rib 221, the inclined section 2221 extends upwardly in a direction radially inward of the support rib 221, and the horizontal section 2222 is connected between the inclined section 2221 and the upper side surface of the connecting plate portion 24, and the horizontal section 2222 extends in a horizontal direction.

[0062] By arranging the inclined section 2221, at least part of the connecting rib 222 can extend upwardly, and by arranging the horizontal section 2222, the connection between the connecting rib 222 and the connecting plate portion 24 can be facilitated. In addition, it can be understood that the inclined section 2221 and the horizontal section 2222 form an included angle, so that the strength of the connecting rib 222 can be improved, thereby further improving the reliability of the filter assembly 100 during operation. During product design, the size of the inclined section 2221, the size of the horizontal section 2222, or the inclination angle of the inclined section 2221 can be adjusted to meet more product design needs.

[0063] In some embodiments of the present application, as shown in FIGS. 1, 2, 3 and 5, the filter assembly 100 further comprises a lifting cup 40, the lifting cup 40 is arranged in the filter cavity 21 in a removable manner, the lifting cup 40 is located above the connecting plate portion 24, and the bottom wall of the lifting cup 40 is adjacent to the connecting plate portion 24.

[0064] As can be understood by those skilled in the art, the lifting cup 40 has a plurality of filter holes, and the pore size of the filter holes on the lifting cup 40 is larger than the pore size of the filter screen of the cylindrical filter portion 20.

[0065] During operation of the dishwasher, the residues on the tableware enter the lifting cup 40 from the opening of the filter cavity 21 together with the water flow, the lifting cup 40 filters the residues with a relatively large size, the water flow filtered by the lifting cup 40 enters the filter cavity 21, and then the filter screen of the cylindrical filter portion 20 continues to filter the water flow to filter out the remaining residues with a relatively small size, and the dishwasher continues to flush the tableware with the filtered water flow.

[0066] In the present embodiment, by arranging the lifting cup 40 which can be removed from the filter cavity 21, the lifting cup 40 can filter the residues with a relatively large size and accommodate the residues with a relatively large size, when the user cleans the filter assembly 100, the lifting cup 40 is removed from the filter cavity 21, the residues in the lifting cup 40 are poured out, and the lifting cup 40 is cleaned, thereby facilitating the cleaning of the lifting cup 40.

[0067] The residue on the cylindrical filter component 20 is small in size, and the user can make the residue separate from the filter screen through water flow flushing. During the flushing of the cylindrical filter component 20, the rotating body 22 can rotate relative to the filter support 30 under the impact of the water flow, so that the user can more easily clean each part of the cylindrical filter component 20, and the rotating body 22 can generate a centrifugal force on the residue on the filter screen during rotation, so that the residue is more easily separated from the filter screen.

[0068] The user can open the dishwasher to flush the cylindrical filter component 20 with external water flow, and a water pump and a spray head can be arranged in the dishwasher to clean the cylindrical filter component 20 with water flow in the dishwasher, thereby realizing self-cleaning of the dishwasher and improving the user experience.

[0069] Therefore, during the cleaning of the filter assembly 100, the filter assembly 100 does not need to be completely taken out of the dishwasher, which can avoid residue from falling from the connection between the filter assembly 100 and the dishwasher to a non-cleaning area, thereby avoiding pollution of the dishwasher caused by residue falling to a part that cannot be taken out, and improving the reliability of the dishwasher during operation.

[0070] It can be understood that the rotating shaft 23 and the shaft hole 33 are both located on the lower side of the filter assembly 100, the lifting cup 40 is located above the connecting plate portion 24, and the bottom wall of the lifting cup 40 is adjacent to the connecting plate portion 24, so that the lifting cup 40 has a larger size in the up-down direction, thereby the residue volume of the lifting cup 40 is larger, and the frequency of cleaning the lifting cup 40 by the user can be further reduced during use, thereby further improving the user experience.

[0071] Preferably, in the up-down direction, the ratio of the distance between the lower side end of the lifting cup 40 and the upper side end of the cylindrical filter component 20 to the height of the cylindrical filter component 20 is 2 / 3-4 / 5, for example, the ratio of the distance between the lower side end of the lifting cup 40 and the upper side end of the cylindrical filter component 20 to the height of the cylindrical filter component 20 can be 2 / 3, 3 / 4 or 4 / 5, thereby the residue volume of the lifting cup 40 can meet the user's use needs, and there is enough space below the bottom wall of the filter cavity 21 to arrange the rotating shaft 23 and the shaft hole 33, and during product design, the ratio of the distance between the lower side end of the lifting cup 40 and the upper side end of the cylindrical filter component 20 to the height of the cylindrical filter component 20 can be adjusted, thereby meeting more product design needs.

[0072] In some embodiments of the present application, as shown in FIGS. 3 and 5, the bottom wall of the lifting cup 40 is formed with a filter protrusion 42 protruding upward, and the filter protrusion 42 is formed by a portion of the bottom wall protruding upward.

[0073] When the residues fall into the cup 40, the residues can be dispersed to the side of the protrusions due to the protrusion structure formed on the bottom wall, and meanwhile, the protrusion part has a filtering effect, so that the cup 40 with the protrusion structure can prevent the residues from being accumulated on the bottom wall of the cup 40 to cause the residue discharge disorder.

[0074] In some embodiments of the present application, as shown in FIGS. 3 and 5, the cross-sectional area of the filtering protrusion 42 gradually decreases in the direction from bottom to top.

[0075] It can be understood that the filtering protrusion 42 is formed in a tapered shape with a narrow top and a wide bottom, so that when the residues slide from the top to the bottom, the top of the filtering protrusion 42 can reduce the contact area with the residues, thereby preventing the residues from being accumulated on the filtering protrusion, and meanwhile, the surface of the filtering protrusion 42 can also guide the residues to automatically separate along the surface of the filtering protrusion 42 to the periphery of the filtering protrusion 42, thereby further ensuring that the residues will not be accumulated on the filtering protrusion 42, so as to improve the filtering effect of the cup 40.

[0076] In some embodiments of the present application, as shown in FIGS. 2 and 3, the filtering support 30 is provided with an annular support part 311 on the side close to the bottom of the cup, and the support part 311 is provided with a support beam 312 extending inward along the radial direction of the support part 311, and the support beam 312 is provided with an axle hole 33, and the rotating shaft 23 is installed in the axle hole 33.

[0077] Therefore, the arrangement of the axle hole 33 on the filtering support 30 can be realized, and the space occupied by the support beam 312 is small, so that the space between the support beam 312 and the annular support part 311 is large, and the water flow out of the space between the support beam 312 and the support part 311 has a high efficiency, thereby improving the filtering efficiency of the filtering assembly 100, and the annular support part 311 and the support beam 312 arranged on the support part 311 have a simple structure, and the design difficulty is low in the product design process, and the production difficulty can be reduced in the production process, and the materials used in the production can be saved, and the production cost is reduced.

[0078] In some embodiments of the present application, as shown in FIGS. 2-4, at least part of the connecting ribs 222 extends upwardly and obliquely, and the connecting plate portion 24 is arranged above the support ribs 221. The connecting plate portion 24, the support beams 312 of the filter support 30 and the plurality of connecting ribs 222 cooperatively define a containing space on the lower side of the filter cavity 21, and the shaft 23 and the shaft hole 33 are both located in the containing space. In this way, the size of the cylindrical filter assembly 20 can be reduced in the up-down direction, which facilitates the arrangement of the cylindrical filter assembly 20, reduces the difficulty of product design during the product design process, and reduces the difficulty of production during the production process. Meanwhile, the cover arranged on the support ribs 221 can form a downwardly inclined inclined surface, and when the residue falls on the support ribs 221, the residue will slide downwardly, thereby reducing the probability of residue accumulation on the support ribs 221.

[0079] In some embodiments of the present application, as shown in FIG. 3, the support beams 312 are formed with support bosses 3121, the support bosses 3121 are formed with the shaft hole 33, and the shaft hole 33 is further provided with a ball bearing 70, the outer ring of the ball bearing 70 is mounted in the shaft hole 33, and the shaft 23 is connected with the inner ring of the ball bearing 70. In this way, the rotatable connection between the shaft 23 and the filter support 30 can be achieved. By arranging the support bosses 3121, the structural strength of the connection between the shaft 23 and the shaft hole 33 can be improved, thereby improving the reliability of the filter assembly 100 during operation. The ball bearing 70 has a long service life and a light weight, which can improve the service life of the filter assembly 100 and facilitate the lightweight design of the filter assembly 100.

[0080] In some embodiments of the present application, as shown in FIG. 3, the side wall of the shaft hole 33 is formed with a drainage groove 331 penetrating the side wall of the shaft hole 33 in the thickness direction. By arranging the drainage groove 331, the water flow and residue entering the shaft hole 33 can be discharged from the drainage groove 331, thereby further reducing the probability of residue blocking the shaft hole 33 and the ball bearing 70, and further improving the reliability of the filter assembly 100 during operation.

[0081] Preferably, the four drainage grooves 331 are uniformly distributed in the circumferential direction of the shaft hole 33. In this way, each drainage groove 331 can discharge water and residue, thereby further improving the reliability of the filter assembly 100 during operation.

[0082] In some embodiments of the present application, as shown in FIG. 1, FIG. 3 and FIG. 5, the filter assembly 100 further comprises a planar filter part 10 connected to the upper end of the filter support 30, and the planar filter part 10 is formed with a mounting hole 11 opposite to the cylindrical filter part 20. During the operation of the dishwasher, the planar filter part 10 can also filter the water flow. When the water flow carrying the residues flows onto the planar filter part 10, most of the water flow can directly pass through the filter screen on the planar filter part 10, and the water flow carrying the residues with larger size can flow into the filter cavity 21, and then pass through the cup 40 and the cylindrical filter part 20 in sequence with the water flow directly flowing into the filter cavity 21.
