[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] Reference below Figure 1-Figure 5 A filter assembly 100 according to an embodiment of the first aspect of the present invention is described.

[0033] The filter assembly 100 according to the first aspect of the present invention is used in a dishwasher. For example, the dishwasher may be a sink dishwasher, a cleaning machine, or a common dishwasher.

[0034] like Figure 1-Figure 4 As shown, it includes: a filter support 30, a cylindrical filter component 20, a planar filter component 10, a cup holder 50 and a cup holder 40.

[0035] Specifically, the cylindrical filter component 20 is arranged in the filter bracket 30, and a filter cavity 21 with an upper end opening is defined in the cylindrical filter component 20. The planar filter component 10 is arranged on the upper side of the filter bracket 30. A mounting hole 11 opposite to the opening of the filter cavity 21 is formed on the planar filter component 10. The cup holder 50 is connected to the filter bracket 30 through the mounting hole 11. The upper end of the cup holder 40 is detachably connected to the cup holder 50, and the lower end of the cup holder 40 extends into the filter cavity 21.

[0036] Among them, a filter screen is provided on the plane filter component 10, the filter screen cover of the cylindrical filter component 20 is arranged on the rotating body 22, the filter bracket 30 is connected to the dishwasher, the cup fixing part 50 is annular, and a plurality of through holes 55 located above the plane filter component are provided on the cup fixing part 50, and a plurality of filter holes are provided on the cup 40, and the aperture of the filter holes on the cup 40 is larger than the aperture of the filter screen of the cylindrical filter component 20.

[0037] During the operation of the dishwasher, during the stage of rinsing tableware, the water flow will circulate and flush the tableware. A part of the water flow carrying the residue on the tableware flows to the planar filter component 10, and the other part enters the lifting cup 40 from the opening of the filter chamber 21, wherein the filter mesh on the planar filter component 10 filters the water flow, and the large residue and the water flow accumulated on the planar filter component 10 pass through the through hole 55 and enter the lifting cup 40 in the filter chamber 21. The lifting cup 40 filters the larger residue in the water flow, and the water flow filtered by the lifting cup 40 enters the filter chamber 21, and then the filter mesh of the cylindrical filter component 20 continues to filter the water flow to filter out the remaining smaller residue, and the dishwasher continues to flush the tableware with the filtered water flow.

[0038] Among them, by setting up the filter component 100, the residue in the water flow can be filtered, and the residue in the water circulating to flush the tableware is less, which can realize the cleaning function of the dishwasher and improve the cleaning effect of the dishwasher.

[0039] It is understandable that when food residues remain on the filter component 100 for a long time, bacteria are likely to grow on the filter component 100. After using the dishwasher, the user will often clean the filter component 100. When there are a lot of food residues in the filter component 100, the user will also clean the filter component 100.

[0040] In this embodiment, by providing a lifting cup 40 that is detachably connected to the lifting cup fixing member 50, the lifting cup 40 can filter and accommodate larger residues. When the user cleans the filter assembly 100, the lifting cup 40 is disconnected from the lifting cup fixing member 50, and then the lifting cup 40 is removed from the filter chamber 21, the residue in the lifting cup 40 is poured out, and the lifting cup 40 is cleaned, thereby facilitating the cleaning of the lifting cup 40.

[0041] When the dishwasher is in operation, the impact of water flow on the lifting cup 40 will cause the lifting cup 40 to shake, so when the lifting cup 40 is placed in the filter chamber 21, it is necessary to fix the lifting cup 40. When the user takes the lifting cup 40 out of the dishwasher, the operating space of the dishwasher is small, and when the lifting cup 40 is connected to the filter bracket 30 or the cylindrical filter component 20, the connection will be blocked by other components, for example, the plane filter component 10 or the wall surface inside the dishwasher, making it difficult for the user to remove the lifting cup 40.

[0042] In this embodiment, by providing a cup fixing member 50, the cup fixing member 50 can extend out of the filter bracket 30, so that the cup 40 is fixed by the cup fixing member 50. When the cup 40 needs to be removed from the cup fixing member 50, the user is less obstructed during the operation, so that the user can more easily remove and take out the cup 40, further improving the user experience.

[0043] During the product design process, the size of the cup-lifting fixture 50 , the shape of the cup-lifting fixture 50 , or the connection method between the cup-lifting fixture 50 and the filter support 30 may be adjusted to meet more product design requirements.

[0044] The residue on the planar filter component 10 and the cylindrical filter component 20 is relatively small, and the user can remove the residue from the filter by flushing with water. The user can turn on the dishwasher and use external water to flush the planar filter component 10 and the cylindrical filter component 20. A water pump and a nozzle can also be set in the dishwasher so that the water inside the dishwasher cleans the planar filter component 10 and the cylindrical filter component 20, thereby realizing self-cleaning of the dishwasher and improving the user experience.

[0045] Therefore, during the cleaning process of the filter assembly 100, the filter assembly 100 does not need to be completely removed from the dishwasher, which can prevent residues from falling from the connection between the filter assembly 100 and the dishwasher to the non-cleaning area, thereby preventing residues from falling to a position that cannot be removed and causing contamination to the dishwasher, thereby improving the reliability of the dishwasher during operation.

[0046] According to the filter assembly 100 of the first aspect of the present invention, by providing the lifting cup 40, food residues in the lifting cup 40 can be removed and poured out without completely removing the filter assembly 100, thereby preventing the residues from falling from the connection between the filter assembly 100 and the dishwasher to the non-cleaning area and causing contamination.

[0047] In some embodiments of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, the upper surface of the plane filter component 10 is an inclined surface that is inclined downward and faces the mounting hole 11. In this way, under the action of gravity, part of the water flow on the plane filter component 10 can pass through the through hole 55 and enter the filter cavity 21 together with the large-sized food residues, thereby reducing the residue of large-sized food residues on the plane filter component 10 and further improving the user experience.

[0048] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, a clamping hole 51 is formed on the cup lifting fixture 50 , and a first clamping hook 42 is provided on the cup lifting 40 , and the first clamping hook 42 is matched with the clamping hole 51 .

[0049] That is to say, the cup lifting 40 and the cup lifting fixing piece 50 are snap-connected. When the cup lifting 40 is placed in the filter chamber 21, the first hook 42 is placed in the clamping hole 51 and the first hook 42 cooperates with the clamping hole 51 to fix the cup lifting 40 by the cup lifting fixing piece 50. When the cup lifting 40 needs to be taken out to pour out the residue, the first hook 42 is removed from the clamping hole 51 to release the fixation of the cup lifting 40 by the cup lifting fixing piece 50. Therefore, the operation of placing and removing the cup lifting 40 is relatively simple, which can further enhance the user experience.

[0050] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the cup lifting 40 is provided with a lifting ear 41 , a first hook 42 is provided on the lifting ear 41 , the cup lifting fixture 50 is cylindrical, an accommodating notch 52 is formed at the upper end of the cup lifting fixture 50 , and part of the lifting ear 41 is provided in the accommodating notch 52 .

[0051] When the lifting cup 40 is placed in the filter chamber 21, the operator can hold the lifting ear 41 to extend the lifting cup 40 into the filter chamber 21, and move the lifting ear 41 to place the first hook 42 into the clamping hole 51, thereby making the operation of placing the lifting cup 40 more convenient. After the lifting cup 40 is placed in the filter chamber 21, the edge of the receiving notch 52 can provide support and limit for the lifting ear 41, thereby improving the stability of the lifting cup 40 in the filter chamber 21.

[0052] During the process of removing the lifting cup 40 from the filter chamber 21, the operator can press the lifting ear 41 to disengage the first hook 42 from the locking hole 51, and then hold the lifting ear 41 to remove the lifting cup 40 from the filter chamber 21. In this way, the difficulty of releasing the clamping connection between the lifting cup 40 and the lifting cup fixing part 50 can be reduced, and the lifting ear 41 can provide a fulcrum, making it easier for the operator to remove the lifting cup 40, thereby further improving the user experience.

[0053] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the filter bracket 30 includes: a bracket body 31 and a connecting frame 32. The upper end of the bracket body 31 is provided with an annular first support portion 311. The connecting frame 32 is annular and is arranged on the radial inner side of the first support portion 311. The cup fixing member 50 is snap-connected to the connecting frame 32.

[0054] The cup lifting 40 and the connecting frame 32 are arranged at intervals. When the user cleans the food residue, the cup lifting 40 can be disconnected from the cup lifting fixture 50 to take out the cup lifting 40 separately. In the process of taking out and putting in the cup lifting 40, the connecting frame 32 will not interfere with the cup lifting 40.

[0055] The bracket body 31 and the connecting frame 32 are separately arranged. During the assembly process, the cylindrical filter arrangement is first placed in the bracket body 31, and then the connecting frame 32 is connected to the first support part 311, and then the cup lifting fixture 50 is connected to the connecting frame 32. Thus, the connecting frame 32 can provide a mounting position for the lower end of the cup lifting fixture 50, and the cylindrical filter component 20 is assembled first during the assembly process. On the premise that the size of the cylindrical filter component 20 is compatible with the bracket body 31 and the connecting frame 32, the size of the cylindrical filter component 20 can be made larger, thereby increasing the volume of the filter chamber 21 and improving the filtering efficiency of the filter assembly 100.

[0056] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, a downwardly extending snap-in flange 321 is formed on the radial inner side of the connecting frame 32 , and a second snap-in hook 56 is provided at the lower end of the cup-lifting fixing member 50 . The second snap-in hook 56 is matched with the lower edge of the snap-in flange 321 .

[0057] In this way, the snap connection between the cup lifting fixture 50 and the connecting frame 32 can be achieved, wherein the snap connection flange 321 can increase the contact area between the connection and the cup lifting fixture 50. After the cup lifting fixture 50 is installed, the snap connection flange 321 can limit the cup lifting fixture 50, so that the cup lifting fixture 50 is more stable on the filter bracket 30. At the same time, the snap connection flange 321 can also increase the limiting area of ​​the cup lifting 40, so that the cup lifting 40 is more stable.

[0058] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the lower end of the filter bracket 30 is provided with an axial hole 33 , and the cylindrical filter component 20 includes a rotating body 22 and a rotating shaft 23 , the upper end of the rotating shaft 23 is fixedly connected to the lower end of the rotating body 22 , and the lower end of the rotating shaft 23 fits in the axial hole 33 .

[0059] That is, the cylindrical filter component 20 is rotatably connected to the filter bracket 30. During the flushing of the cylindrical filter component 20, the rotating body 22 can rotate relative to the filter bracket 30 under the impact of the water flow, so that the user can more easily clean various parts of the cylindrical filter component 20, and the rotating body 22 can generate a centrifugal force on the residue on the filter screen during the rotation process, so that the residue is more easily separated from the filter screen.

[0060] Among them, the rotating shaft 23 is arranged at the lower end of the rotating body 22, and the axial hole 33 is arranged at the lower end of the filter bracket 30. In this way, on the one hand, the rotating shaft 23 will not occupy the space above the filter chamber 21, and the size of the lifting cup 40 located in the filter chamber 21 can be made larger. During use, the lifting cup 40 can accommodate more residues, thereby reducing the number of times the user cleans the lifting cup 40, further improving the user's experience; on the other hand, the rotation center of gravity of the cylindrical filter component 20 will move downward, and during the impact of water flow, the stability of the filter assembly 100 can be improved.

[0061] In some embodiments of the present invention, Figure 4 As shown, the lower end of the filter bracket 30 is provided with an annular second support portion 312, the second support portion 312 is provided with a support beam 313, the support beam 313 extends radially along the second support portion 312, the support beam 313 is provided with an axial hole 33, a ball bearing 34 is provided in the axial hole 33, and the rotating shaft 23 is connected to the ball bearing 34.

[0062] Thus, the arrangement of the shaft hole 33 on the filter bracket 30 can be realized, and the rotatable connection between the rotating shaft 23 and the filter bracket 30 can be realized. Among them, the space occupied by the support beam 313 is small, so that the space between the support beam 313 and the annular second support portion 312 is large, and the efficiency of water flowing out of the space between the support beam 313 and the second support portion 312 is high, thereby improving the filtering efficiency of the filter assembly 100. The annular second support portion 312 and the support beam 313 arranged on the second support portion 312 have a relatively simple structure, and the design difficulty is relatively low during the product design process. During the production process, the production difficulty can be reduced, and the materials required for production can be saved, thereby reducing the production cost.

[0063] In some embodiments of the present invention, Figure 2As shown, the rotating body 22 includes a connecting plate portion 24, the connecting plate portion 24 is located at the lower end of the rotating body 22, the lifting cup 40 is located above the connecting plate portion 24, and the lower end of the lifting cup 40 extends to a position adjacent to the connecting plate portion 24. Among them, the upper end of the rotating shaft 23 is connected to the lower surface of the connecting plate portion 24. It can be understood that the rotating shaft 23 and the shaft hole 33 are both located at the lower side of the filter assembly 100. The lower side of the lifting cup 40 extends to a position adjacent to the connecting plate portion 24, which can make the size of the lifting cup 40 larger in the vertical direction, thereby making the residue holding capacity of the lifting cup 40 larger. During the use of the user, the frequency of the user cleaning the lifting cup 40 can be further reduced, thereby further improving the user experience.

[0064] Among them, preferably, in the up and down directions, the ratio of the distance between the lower side end edge of the lifting cup 40 and the upper side end edge 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 edge of the lifting cup 40 and the upper side end edge 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 holding capacity of the lifting cup 40 can meet the user's usage needs, and there is enough space under the bottom wall of the filter chamber 21 to arrange the rotating shaft 23 and the shaft hole 33. During the product design process, the ratio of the distance between the lower side end edge of the lifting cup 40 and the upper side end edge of the cylindrical filter component 20 to the height of the cylindrical filter component 20 can be adjusted to meet more product design needs.

[0065] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the rotating body 22 includes a connecting plate portion 24, which is located at the lower end of the rotating body 22. A plurality of water holes 25 are provided on the circumferential side of the connecting plate portion 24. For example, the water holes 25 may be two, three or four. The upper end of the rotating shaft 23 is connected to the lower side surface of the connecting plate portion 24.

[0066] The connecting plate portion 24 can increase the connection area between the rotating shaft 23 and the rotating body 22 , making it easier to ensure that the connection strength between the rotating shaft 23 and the rotating body 22 meets the use requirements during product design.

[0067] Water can flow out from the lower end of the cylindrical filter component 20 through the water hole 25, and the water hole 25 can filter the water, thereby ensuring the filtering efficiency of the cylindrical filter component 20. During the product design process, the size of the connecting plate portion 24, the size of the water hole 25 or the number of the water holes 25 can be adjusted to meet more product design needs.

[0068] In some embodiments of the present invention, Figure 4 and Figure 5As shown, the connecting plate portion 24 is opposite to the shaft hole up and down to block at least part of the shaft hole 33 in the up and down direction. It is understandable that the cylindrical filter component 20 cannot completely filter the food residue in the water flow, and when the cylindrical filter component 20 is cleaned, the water flow will wash away the residue of the filter screen, wherein a ball bearing 34 is arranged in the shaft hole 33, and the connecting plate portion 24 provides shielding for the shaft hole in the up and down direction, which can reduce the probability of water flow and residue entering the shaft hole 33, thereby reducing the probability of residue blocking the shaft hole 33 and the ball bearing 34 in the shaft hole 33, and improving the reliability of the filter assembly 100.

[0069] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, an annular support rib 221 and a plurality of connecting ribs 222 are provided at the bottom of the rotating body 22. For example, the connecting ribs 222 may be two, three or four. The connecting plate portion 24 is provided on the radial inner side of the support rib 221. The outer end of the connecting rib 222 is connected to the radial inner side of the support rib 221, and the inner end of the connecting rib 222 is connected to the connecting plate portion 24.

[0070] Therefore, the two connected connecting ribs 222 and the connecting plate portion 24 can cooperate to define the water hole 25, and the size of the water hole 25 is relatively large. It can be understood that the rotating body 22 and the filter screen are both made of materials with low density. During the operation of the filter assembly 100, the cylindrical filter component 20 also exerts a small force on the rotating shaft 23. By connecting the connecting plate portion 24 with multiple connecting ribs 222, the connection strength between the connecting ribs 222 and the connecting plate portion 24 can meet the requirements of use.

[0071] During the product design process, parameters such as the size and shape of the connecting ribs 222 or the size of the supporting ribs 221 may be adjusted to meet more product design requirements.

[0072] In some embodiments of the present invention, Figure 2 and Figure 5 As shown, at least part of the connecting rib 222 extends upwardly and obliquely, and the connecting plate portion 24 is arranged above the supporting rib 221. In this way, in the vertical direction, the rotating shaft 23 can extend upward into the rotating body 22, thereby reducing the size of the cylindrical filter component 20 in the vertical direction, thereby facilitating the arrangement of the cylindrical filter component 20, reducing the difficulty of product design in the process of product design, and reducing the difficulty of production in the process of production. At the same time, a downwardly inclined inclined surface can be formed on the supporting rib 221, and when the residue falls on the supporting rib 221, the residue will slide downward, thereby reducing the probability of the residue accumulating on the supporting rib 221.

[0073] In some embodiments of the present invention, Figure 2 and Figure 5As shown, the connecting rib 222 includes: an inclined section 2221 and a horizontal section 2222, the inclined section 2221 is connected between the horizontal section 2222 and the supporting rib 221, and in the radial inward direction of the supporting rib 221, the inclined section 2221 extends upward at an angle, 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.

[0074] By providing the inclined section 2221, at least part of the connecting rib 222 can be extended upwardly inclined, and by providing the horizontal section 2222, the connection between the connecting rib 222 and the connecting plate portion 24 can be easily achieved. In addition, it can be understood that the inclined section 2221 and the horizontal section 2222 form an 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. In the process of product design, parameters such as 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.

[0075] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the bottom wall of the cup 40 is formed with an upwardly protruding filtering protrusion 43, which is formed by a portion of the bottom wall protruding upward. In the direction from bottom to top, the cross-sectional area of ​​the filtering protrusion 43 gradually decreases.

[0076] When the residue falls into the lifting cup 40, the residue can be dispersed to the surrounding side of the protrusion due to the protrusion structure formed on the bottom wall. At the same time, the protrusion also has a filtering effect. Therefore, the lifting cup 40 with a protrusion structure can prevent food residue from accumulating on the bottom wall of the lifting cup 40 and causing the residue to be discharged unsmoothly.

[0077] It can be understood that the filter protrusion 43 is formed into a cone that is narrow at the top and wide at the bottom. In this way, when the residue slides from the top to the bottom, the top of the filter protrusion 43 can reduce the contact area with the residue, thereby preventing the residue from accumulating on the filter protrusion. At the same time, the surface of the filter protrusion 43 can also guide the residue, so that the residue can be automatically separated along the surface of the filter protrusion 43 to the periphery of the filter protrusion 43, thereby further ensuring that the residue will not accumulate on the filter protrusion 43, thereby improving the filtering effect of the cup 40.

[0078] In some embodiments of the present invention, Figure 1As shown, the cup-lifting fixture 50 is provided with a first indicator 54, and the plane filter component 10 is provided with a second indicator 12. The first indicator 54 cooperates with the second indicator 12 to indicate the assembly position of the cup-lifting fixture 50. The first indicator 54 and the cup-lifting fixture 50 may be separate parts, and the first indicator 54 is clamped on the cup-lifting fixture 50. The first indicator 54 and the cup-lifting fixture 50 may also be an integrated part. During the assembly process, when the relative position of the first indicator 54 and the second indicator 12 reaches the set position, the cup-lifting fixture 50 is assembled in place. For example, the first indicator 54 and the second indicator 12 may be indicator arrows. When the first indicator 54 is opposite to the second indicator 12, the cup-lifting fixture 50 is assembled in place.

[0079] In some embodiments of the present invention, Figure 2 As shown, the filter assembly 100 further includes: a sterilizing element 60 , which is disposed on the filter support 30 and is located on a side of the cylindrical filter component 20 that is away from the opening of the filter cavity 21 .

[0080] During the process of the dishwasher rinsing the dishes in a cycle, water flows in from one side of the opening of the filter chamber 21 and then flows out from the other side of the filter chamber 21. In this way, the outflowing water can contact the sterilizing element 60, and the sterilizing element 60 can sterilize the outflowing water, thereby improving the cleaning effect of the dishes. It can be understood that the opening of the filter chamber 21 is usually arranged in a direction, that is, the sterilizing element 60 is arranged at the lower end of the filter bracket 30. After the dishwasher is used, water is likely to remain at the lower end of the filter bracket 30, and the residual water is likely to breed bacteria. By setting the sterilizing element 60, the number of bacteria breeding below the filter bracket 30 can be reduced.

[0081] Among them, preferably, the sterilization component 60 is a silver ion component, which can realize the sterilization function of the sterilization component 60; the sterilization component 60 is arranged on the lower side of the filter bracket 30, so that the sterilization effect of the sterilization component 60 on the space below the filter bracket 30 can be improved.
