[0034] 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.

[0035] Reference below Figure 1-Figure 5 A filter assembly 100 according to an embodiment of the first aspect of the present invention is described.

[0036] The filter assembly 100 according to the first embodiment of the utility model is used in a dishwasher. For example, the dishwasher can be used in a sink dishwasher, a cleaning machine or a common dishwasher.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the filter assembly 100 includes: a water cup (not shown in the drawings), a filter support 30 and a cylindrical filter component 20.

[0038] Specifically, the filter bracket 30 is installed in the water cup, and an axial hole 33 is provided at the lower end of the filter bracket 30. The cylindrical filter component 20 is rotatably arranged in the filter bracket 30. A filter cavity 21 with an upper end opening is defined in the cylindrical filter component 20. 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 is located outside the filter cavity 21. The lower end of the rotating shaft 23 is fitted in the axial hole 33.

[0039] It is understandable to those skilled in the art that the filter cover of the cylindrical filter component 20 is arranged on the rotating body 22, the filter bracket 30 is connected to the dishwasher, and the rotating shaft 23 cooperates with the shaft hole 33 to realize the rotatable connection between the rotating body 22 and the filter bracket 30.

[0040] During the operation of the dishwasher, when rinsing tableware, the water flow will circulate and rinse the tableware. The residue on the tableware enters the filter chamber 21 from the opening of the filter chamber 21 together with the water flow, and then the filter screen of the cylindrical filter component 20 filters the water flow. The filtered water flow enters the water cup, and the dishwasher flushing pump draws water from the water cup to continue to rinse the tableware.

[0041] 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.

[0042] The rotating shaft 23 is connected to the lower end of the rotating body 22 and is located on the outside of the filter chamber 21. Therefore, the rotating shaft 23 will not occupy the space in the filter chamber 21, so that the volume of the filter chamber 21 can be larger, thereby making the filtering area in the filter chamber 21 larger, and improving the filtering efficiency of the filter assembly 100. When a lifting cup 40 is provided in the filter chamber 21, the size of the lifting cup 40 provided in the filter chamber 21 can be larger, and the lifting cup 40 can accommodate more residues. During use, the number of times the user cleans the lifting cup 40 can be reduced, thereby further improving the user experience.

[0043] At the same time, the rotating shaft 23 is connected to the lower end of the rotating body 22, so that the center of gravity of the cylindrical filter component 20 can be moved downward. When the water flow impacts, the cylindrical filter component 20 will be more stable. The axial hole 33 is arranged at the lower end of the filter bracket 30, and the ball bearing 70 arranged in the axial hole 33 is also located at the lower end of the filter bracket 30. Therefore, the center of gravity of the filter assembly 100 can be moved downward, thereby improving the stability of the filter assembly 100 during operation.

[0044] 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.

[0045] When the user cleans the filter screen of the cylindrical filter component 20, the user first removes the large-sized residues in the filter chamber 21. The user can directly remove the residues in the filter chamber 21, or the user can set a lifting cup 40 in the filter chamber 21 to filter the large-sized residues through the lifting cup 40. When cleaning, the user can take out the lifting cup 40 and pour out the large-sized residues, which can improve the cleaning efficiency and reduce the difficulty of operation.

[0046] The user can use water to flush the smaller-sized residues remaining on the filter to separate the residues from the filter. During the flushing process 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. In this way, 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 residues on the filter during the rotation process, thereby making it easier for the residues to separate from the filter.

[0047] Among them, the user can open the dishwasher and use external water flow to rinse the cylindrical filter component 20. A water pump and a nozzle can also be set in the dishwasher to make the water flow inside the dishwasher clean the cylindrical filter component 20, thereby realizing the self-cleaning of the dishwasher and improving the user experience.

[0048] According to the filter assembly 100 of the first aspect of the utility model, on the one hand, the rotating shaft 23 does not occupy the space of the filter chamber 21, so that the filtering area in the filter chamber 21 can be larger, thereby improving the filtering efficiency of the filter assembly 100. On the other hand, the center of gravity of the filter assembly 100 is moved downward, which can improve the stability of the filter assembly 100 during operation.

[0049] In some embodiments of the present invention, Figure 2-Figure 4 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.

[0050] 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.

[0051] Water can flow out from the lower end of the cylindrical filter component 20 through the water hole 25, 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.

[0052] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the connecting plate portion 24 is opposite to the shaft hole 33 in the vertical direction, and the connecting plate portion 24 blocks at least part of the shaft hole 33 in the vertical 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 70 is arranged in the shaft hole 33, and the connecting plate portion 24 provides shielding for the shaft hole 33 in the vertical 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 70 in the shaft hole 33, and improving the reliability of the filter assembly 100.

[0053] In some embodiments of the present invention, Figure 2 As shown, the connecting plate portion 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 made more stable, and during the operation of the filter assembly 100, the reliability of the cylindrical filter component 20 on the filter bracket 30 can be improved, and the noise generated when the cylindrical filter component 20 rotates can be reduced, further improving the user experience.

[0054] In some embodiments of the present invention, Figure 3 and Figure 4 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 supporting rib 221. One end of the connecting rib 222 is connected to the supporting rib 221, and the other end of the connecting rib 222 is connected to the connecting plate portion 24.

[0055] 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.

[0056] 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.

[0057] In some embodiments of the present invention, Figure 2-Figure 4 As 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.

[0058] 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.

[0059] In some embodiments of the present invention, Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the filter assembly 100 further includes a lifting cup 40 , which is removably disposed in the filter cavity 21 , and 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 .

[0060] It is understandable to those skilled in the art that the lifting cup 40 has a plurality of filtering holes, and the aperture of the filtering holes on the lifting cup 40 is larger than the aperture of the filter screen of the cylindrical filtering component 20 .

[0061] When the dishwasher is in operation, the residue on the tableware enters the lifting cup 40 together with the water flow from the opening of the filter chamber 21. The lifting cup 40 filters the larger residue in the water flow. The water flow filtered by the lifting cup 40 enters the filter chamber 21, and then the filter screen of the cylindrical filter component 20 continues to filter the water flow to filter out the remaining smaller residue. The dishwasher continues to rinse the tableware with the filtered water flow.

[0062] In this embodiment, by providing a lifting cup 40 that can be removed from the filter chamber 21, the lifting cup 40 can filter larger residues and accommodate larger residues. When the user cleans the filter assembly 100, 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.

[0063] The residue on the cylindrical filter component 20 is small in size, and the user can use water to flush the residue to separate it from the filter. During the flushing process 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. In this way, 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 during the rotation process, thereby making it easier for the residue to separate from the filter.

[0064] Among them, the user can open the dishwasher and use external water flow to rinse the cylindrical filter component 20. A water pump and a nozzle can also be set in the dishwasher to make the water flow inside the dishwasher clean the cylindrical filter component 20, thereby realizing the self-cleaning of the dishwasher and improving the user experience.

[0065] 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 part that cannot be removed and causing contamination to the dishwasher, thereby improving the reliability of the dishwasher during operation.

[0066] It can be understood that the rotating shaft 23 and the axial 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, which can make the size of the lifting cup 40 in the up and down directions larger, thereby making the residue holding capacity of the lifting cup 40 larger. During the user's use, the frequency of the user cleaning the lifting cup 40 can be further reduced, thereby further improving the user's experience.

[0067] 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.

[0068] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the bottom wall of the lifting cup 40 is formed with a filtering protrusion 42 protruding upwards, and the filtering protrusion 42 is formed by a portion of the bottom wall protruding upwards.

[0069] 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.

[0070] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the cross-sectional area of ​​the filtering protrusion 42 gradually decreases in the direction from bottom to top.

[0071] It can be understood that the filter protrusion 42 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 42 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 42 can also guide the residue, so that the residue can be automatically separated along the surface of the filter protrusion 42 to the periphery of the filter protrusion 42, thereby further ensuring that the residue will not accumulate on the filter protrusion 42, thereby improving the filtering effect of the cup lifting 40.

[0072] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, a ring-shaped support portion 311 is provided on one side of the filter bracket 30 close to the bottom of the water cup, a support beam 312 is provided on the support portion 311, the support beam 312 extends radially inward along the support portion 311, an axis hole 33 is provided on the support beam 312, and the rotating shaft 23 is installed in the axis hole 33.

[0073] In this way, the arrangement of the axial hole 33 on the filter bracket 30 can be realized, and the support beam 312 occupies a smaller space, so that the space between the support beam 312 and the annular support portion 311 is larger, and the efficiency of water flowing out from the space between the support beam 312 and the support portion 311 is higher, thereby improving the filtering efficiency of the filter assembly 100. The annular support portion 311 and the support beam 312 arranged on the support portion 311 have a relatively simple structure. During the product design process, the design difficulty is relatively low. During the production process, the production difficulty can be reduced, and the materials required for production can be saved, thereby reducing the production cost.

[0074] In some embodiments of the present invention, Figure 2-Figure 4 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. The connecting plate portion 24, the supporting beam 312 of the filter bracket 30 and the plurality of connecting ribs 222 cooperate to define a receiving space located at the lower side of the filter cavity 21, and the rotating shaft 23 and the shaft hole 33 are both located in the receiving space. In this way, the size of the cylindrical filter component 20 can be reduced in the up-down direction, thereby facilitating the arrangement of the cylindrical filter component 20, reducing the difficulty of product design during product design, and reducing the difficulty of production during production. At the same time, the cover is arranged on the supporting rib 221 to form a downwardly inclined inclined surface. 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.

[0075] In some embodiments of the present invention, Figure 3 As shown, a support boss 3121 is formed on the support beam 312, and an axial hole 33 is formed on the support boss 3121. A ball bearing 70 is also arranged in the axial hole 33. The outer ring of the ball bearing 70 is installed in the axial hole 33, and the rotating shaft 23 is connected to the inner ring of the ball bearing 70. Thus, the rotating shaft 23 and the filter bracket 30 can be rotatably connected. The support boss 3121 can improve the structural strength of the connection between the rotating shaft 23 and the axial hole 33, 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 is conducive to realizing a lightweight design of the filter assembly 100.

[0076] In some embodiments of the present invention, Figure 3As shown, a drainage groove 331 is formed on the side wall of the shaft hole 33 and penetrates the side wall of the shaft hole 33 in the thickness direction. By providing the drainage groove 331, the water flow and residues entering the shaft hole 33 can be discharged from the drainage groove 331, thereby further reducing the probability of residues blocking the shaft hole 33 and the ball bearing 70, and further improving the reliability of the filter assembly 100 during operation.

[0077] Preferably, there are four drainage grooves 331 , and the four drainage grooves 331 are evenly distributed in the circumferential direction of the axial hole 33 , so that each drainage groove 331 can drain water and discharge residues, thereby further improving the reliability of the filter assembly 100 during operation.

[0078] In some embodiments of the present invention, Figure 1 , Figure 3 and Figure 5 As shown, the filter assembly 100 further includes: a plane filter component 10, the plane filter component 10 is connected to the upper end of the filter bracket 30, and a mounting hole 11 is formed on the plane filter component 10, which is opposite to the cylindrical filter component 20. During the operation of the dishwasher, the plane filter component 10 can also filter the water flow. When the water flow carrying the residue flows to the plane filter component 10, most of the water flow can directly pass through the filter screen on the plane filter component 10, and the other water flow carrying the larger residue can flow into the filter chamber 21, and then pass through the cup 40 and the cylindrical filter component 20 together with the water flow directly flowing into the filter chamber 21.

[0079] By providing the planar filter component 10 , the filter area of ​​the filter assembly 100 can be increased, thereby further improving the filter efficiency of the filter assembly 100 .

[0080] In some embodiments of the present invention, Figure 1 and Figure 5 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 54 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.

[0081] In some embodiments of the present invention, Figure 1 , Figure 3 and Figure 5 As shown, the filter assembly 100 also includes a cup-lifting fixture 50, wherein the cup-lifting fixture 50 is connected to the filter bracket 30 through the mounting hole 11, and a plurality of through holes 54 located above the planar filter element are provided on the cup-lifting fixture 50, the upper end of the cup-lifting fixture 50 is detachably connected to the cup-lifting fixture 50, and the lower end of the cup-lifting fixture 40 extends into the filter chamber 21.

[0082] During operation of the dishwasher, the filter screen on the planar filter component 10 filters the water flow, and large residues and the water flow accumulated on the planar filter component 10 pass through the through hole 54 and enter the cup 40 in the filter chamber 21 .

[0083] 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.

[0084] 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.

[0085] 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.

[0086] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, a latch hole 51 is formed on the cup lifting fixture 50 , and a first latch hook 411 is provided on the cup lifting 40 , and the first latch hook 411 is matched with the latch hole 51 .

[0087] 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 411 is placed in the clamping hole 51 and the first hook 411 cooperates with the clamping hole 51 to fix the cup lifting 40 to the cup lifting fixing piece 50. When the cup lifting 40 needs to be taken out, the first hook 411 is removed from the clamping hole 51 to release the fixation of the cup lifting 40 to 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.

[0088] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the cup lifting 40 is provided with a lifting ear 41 , a first hook 411 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 .

[0089] 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 411 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.

[0090] 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 411 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.

[0091] In some embodiments of the present invention, Figure 3 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.

[0092] That is to say, 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 portion 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.

[0093] In some embodiments of the present invention, Figure 2 and Figure 3 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 55 is provided at the lower end of the cup-lifting fixing member 50 . The second snap-in hook 55 is matched with the lower edge of the snap-in flange 321 .

[0094] 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.

[0095] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the cup-lifting fixture 50 is provided with a first indicator 53, and the plane filter component 10 is provided with a second indicator 12. The first indicator 53 cooperates with the second indicator 12 to indicate the assembly position of the cup-lifting fixture 50. The first indicator 53 and the cup-lifting fixture 50 may be separate parts, and the first indicator 53 is clamped on the cup-lifting fixture 50. The first indicator 53 and the cup-lifting fixture 50 may also be an integrated part. During the assembly process, when the relative position of the first indicator 53 and the second indicator 12 reaches the set position, the cup-lifting fixture 50 is assembled in place. For example, the first indicator 53 and the second indicator 12 may be indicator arrows. When the first indicator 53 is opposite to the second indicator 12, the cup-lifting fixture 50 is assembled in place.

[0096] In some embodiments of the present invention, Figure 2 and Figure 3 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 .

[0097] 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.

[0098] 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.
