[0035] 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.

[0036] Reference below Figure 1-Figure 6 A filter assembly 100 according to an embodiment of the first aspect of the present invention is described.

[0037] like Figure 1-Figure 4 As shown, the filter assembly 100 according to the embodiment of the utility model is used for a dishwasher, and includes: a filter support 30, a cylindrical filter component 20, a connecting frame 70, a flat filter component 10 and a cup support 50.

[0038] The filter screen of the planar filter component 10 is generally formed into a planar structure, which can cover a larger area and can be used to capture larger food residues and particles.

[0039] The cylindrical filter assembly 100 is a hollow cylinder, i.e., a tubular shape, and the accommodating cavity 21 formed inside can be used to carry food residues and cleaning water, and is mainly used to intercept smaller food residues in the water flow, and can perform secondary filtration on the cleaning water.

[0040] The filter bracket 30 can provide installation space and support for the cylindrical filter component 20. The filter bracket 30 is connected to the water cup of the dishwasher so that the filter assembly 100 is stably integrated inside the dishwasher.

[0041] The connecting frame 70 is used to connect the filter bracket 30, the cup holder 50 and the flat filter component 10 as a whole, so that the filter assembly 100 can be assembled as an integral part. In this way, when the filter assembly 100 is installed in the dishwasher or taken out of the dishwasher, it can be put in or taken out as a whole, thereby improving the convenience of installation and disassembly of the dishwasher and the filter assembly 100, thereby improving the convenience of maintenance of the dishwasher and improving the user experience.

[0042] The cup holder 50 is used to provide an installation space and a fixing function for the cup holder 40 , so as to prevent the cup holder 40 from shaking due to the impact of water flow during the operation of the dishwasher.

[0043] Specifically, the cylindrical filter component 20 is disposed in the filter bracket 30, and the inner side of the cylindrical filter component 20 defines a receiving chamber 21 with a top opening. In this way, food residues or particles are facilitated to enter the cylindrical filter component 20, thereby filtering the food residues or particles.

[0044] The connecting frame 70 is connected to the filter bracket 30, and is arranged at the opening position of the accommodating chamber 21 and extends in a ring shape along the opening of the accommodating chamber 21. In this way, the connecting frame 70 can be prevented from being blocked at the opening position of the accommodating chamber 21, so that food residues and washing water can smoothly enter the accommodating chamber 21 for secondary filtration, thereby ensuring the filtering effect of the cylindrical filter component 20.

[0045] The planar filter component 10 is supported on the connecting frame 70, that is, the cylindrical filter component 20, the connecting frame 70 and the filter bracket 30 are all arranged at the lower part of the planar filter component 10. Therefore, when the dishwasher is working, the cleaning water and food residues will first pass through the planar filter assembly 100, and then enter the cylindrical filter assembly 100 through the planar filter assembly 100 for secondary filtration.

[0046] The plane filter component 10 has a connecting hole 11 that passes through the plane filter component 10, and the connecting hole 11 is opposite to and connected to the top opening of the accommodating chamber 21. In other words, food residues and washing water enter the accommodating chamber 21 in the cylindrical filter assembly 100 through the connecting hole 11 for secondary filtration.

[0047] The cup holder 50 is arranged on the upper side of the planar filter component 10 , and the lower end of the cup holder 50 is connected to the connecting frame 70 through the connecting hole 11 , and the planar filter component 10 is fixed between the connecting frame 70 and the cup holder 50 .

[0048] It can be understood that the connecting frame 70 and the cup lifting bracket 50 cooperate to connect the planar filter component 10 and the filter bracket 30 as a whole, and the cylindrical filter component 20 is arranged inside the filter bracket 30. Therefore, the design of the connecting frame 70 and the cup lifting bracket 50 can assemble the filter assembly 100 into an integral part, which is convenient for the user to lift the entire filter assembly 100 for cleaning or inspection when cleaning or maintaining the dishwasher, thereby improving the convenience of maintenance of the dishwasher and enhancing the user experience.

[0049] When assembling the entire filter assembly 100, the cylindrical filter assembly 100 can be first installed in the filter bracket 30, and then the filter bracket 30 and the connecting frame 70 are connected. Then, the planar filter component 10 is arranged on the upper surface of the connecting frame 70, and the lower part of the cup holder 50 is fixed to the connecting frame 70 through the connecting hole 11.

[0050] According to the filter assembly 100 of the present invention, by providing the connecting frame 70 and the cup holder 50, the filter assembly 100 can be assembled into an integral part. In this way, when the filter assembly 100 is installed in the dishwasher or taken out of the dishwasher, it can be put in or taken out as a whole, thereby improving the convenience of installation and disassembly of the dishwasher and the filter assembly 100. As a result, the convenience of maintenance of the dishwasher can be improved, and the user experience can be improved.

[0051] According to some embodiments of the present invention, Figure 3 As shown, the connecting frame 70 is sleeved on the radial outer side of the lower end of the cup lifting bracket 50, and the connecting frame 70 is connected with the cup lifting bracket 50 by snapping. Among them, "the connecting frame 70 is sleeved on the radial outer side of the lower end of the cup lifting bracket 50" means that the connecting frame 70 is not simply directly connected to the lower end of the cup lifting bracket 50, but is sleeved. Such a design can increase the contact area between the two components and improve the stability of the connection. At the same time, it can also reduce the overall size of the connecting frame 70 and the cup lifting bracket 50 after being connected, thereby improving the integration of the filter assembly 100.

[0052] "The connecting frame 70 is snap-connected to the cup lifting bracket 50". It can be understood that the connecting frame 70 and the cup lifting bracket 50 are detachably connected, which is beneficial to the assembly and disassembly between the connecting frame 70 and the cup lifting bracket 40, and further facilitates the assembly and cleaning of the filter assembly 100. At the same time, when one of the connecting frame 70 or the cup lifting bracket 50 is damaged, only the damaged part can be replaced, thereby reducing the overall maintenance cost.

[0053] Furthermore, the snap-fit ​​connection is a simple and reliable assembly method, and there are many forms of snap-fit ​​connection, such as the snap-fitting of a protrusion and a groove, the mutual cooperation of a mortise and tenon structure, etc.

[0054] According to some embodiments of the present invention, Figure 4 As shown, a plurality of first convexities 71 protruding radially inward are formed on the inner wall of the connecting frame 70, and the plurality of first convexities 71 are arranged at intervals along the circumference of the connecting frame 70. The lower end of the cup lifting bracket 50 has a plurality of first hooks 51 extending downward, and the hooks of the first hooks 51 abut against the lower surface of the first convexities 71. It can be understood that the connection between the connecting frame 70 and the cup lifting bracket 50 is completed by clamping the first hooks 51 on the first convexities 71, wherein the structures of the convexities and the hooks are relatively simple, and the manufacture and operation are relatively convenient, thereby reducing the manufacturing difficulty of the connecting frame 70 and the cup lifting bracket 50, and reducing the difficulty of clamping the connecting frame 70 and the cup lifting bracket 50, thereby reducing the production cost of the entire filter assembly 100, and improving the convenience of assembling and disassembling the filter assembly 100.

[0055] For example, the number of the first latching protrusions 71 and the first latching hooks 51 may be two, three or more, and the number and positions of the first latching protrusions 71 and the first latching hooks 51 correspond one to one.

[0056] According to some embodiments of the present invention, Figure 4 As shown, a support groove 13 is formed on the plane filter component 10, which is concave toward one side of the water cup. The support groove 13 is annular, and the connecting hole 11 is formed on the bottom wall of the support groove 13. The cup lifting bracket 50 has a support ring 52, and the support ring 52 is arranged in the support groove 13. It can be understood that the plane filter component 10 is clamped between the support ring 52 of the cup lifting bracket 50 and the upper surface of the connecting frame 70, so that the contact area between the plane filter component 10 and the cup lifting bracket 50 and the connecting frame 70 can be increased, thereby increasing the assembly stability of the plane filter component 10, the cup lifting bracket 50 and the connecting frame 70, and thus increasing the assembly stability of the entire filter assembly 100. Therefore, when the filter assembly 100 needs to be cleaned, the entire filter assembly 100 can be easily lifted out without falling and spilling the internal residue into the dishwasher, thereby improving the user experience.

[0057] According to some embodiments of the present invention, Figure 4 As shown, a sealing protrusion 12 protruding downward is formed on the peripheral edge of the bottom wall of the support groove 13, and a sealing groove 73 is formed on the connecting frame 70. The sealing protrusion 12 is matched in the sealing groove 73 to seal the gap between the cup holder 50 and the connecting frame 70. In this way, the risk of leakage of washing water and food residues from the connection between the two components can be reduced, and the risk of secondary contamination of tableware can be reduced. At the same time, the structure of the groove and the protrusion is relatively simple, thereby reducing the difficulty of manufacturing the planar filter component 10 and the connecting frame 70, and then reducing the difficulty of manufacturing the entire filter assembly 100 and reducing the production cost.

[0058] Furthermore, for example Figure 4 As shown, the sealing groove 73 is formed as an upwardly open groove, and the sealing protrusion 12 cooperates in the sealing groove 73 to form a double-bend barrier.

[0059] According to some embodiments of the present invention, Figure 4 As shown, the sealing protrusion 12 is formed by bending downwards the peripheral edge of the bottom wall of the supporting groove 13. Among them, bending is a relatively direct and cost-effective processing method, which does not require complex molds or additional assembly steps, thereby helping to reduce the production cost of the planar filter component 10; at the same time, it can be understood that the sealing protrusion 12 and the planar filter component 10 are integrally formed, so that the gap between the sealing protrusion 12 and the planar filter component 10 can be further reduced, thereby further reducing the probability of residue leakage.

[0060] According to some embodiments of the present invention, Figure 3 As shown, the connecting frame 70 is connected to the inner wall of one end of the filter support 30 close to the opening, and the connecting frame 70 is connected to the filter support 30 by snapping. It can be understood that the connecting frame 70 is arranged on the radial inner side of the filter support 30, so that the space occupied by the connecting frame 70 can be reduced, the integration of the filter assembly 100 can be improved, and the overall installation space of the filter assembly 100 can be reduced. In addition, the connecting frame 70 is connected to the filter support 30 by snapping, wherein the snap connection structure is simple and easy to install and disassemble, thereby improving the installation speed and maintenance convenience of the connecting frame 70 and the filter support 30, and further improving the cleaning convenience and completeness of the filter assembly 100.

[0061] According to some embodiments of the present invention, Figure 4-Figure 6 As shown, the outer peripheral wall of the connecting frame 70 is formed with a second clamping protrusion 72 extending radially outward along the connecting frame 70, and the filter support 30 is formed with a clamping hole 31 extending in the radial direction of the accommodating cavity 21, and the second clamping protrusion 72 extends into the clamping hole 31. Among them, the structure of the clamping protrusion and the clamping hole 31 is relatively simple and easy to manufacture. Therefore, by connecting the connecting frame 70 and the filter support 30 using the structure of the second clamping protrusion 72 and the clamping hole 31, the manufacturing cost of the connecting frame 70 and the filter support 30 can be reduced, thereby reducing the production cost of the filter assembly 100.

[0062] According to some embodiments of the utility model, the connection frame 70 cooperates with the filter bracket 30 to define a limit groove that opens downward, and the limit groove is formed in an annular shape, and the upper end of the cylindrical filter component 20 can be rotatably engaged in the limit groove. It can be understood that the cylindrical filter component 20 is rotatable relative to the filter bracket 30, so that the problem of food residues accumulating at the same position on the cylindrical filter component 20 can be effectively solved, which is conducive to improving the filtering efficiency; at the same time, the limit groove can guide the rotation trajectory of the cylindrical filter component 20, thereby ensuring the stability of the cylindrical filter component 20 during the rotation process.

[0063] For example, refer to Figure 6 The lower end of the cylindrical filter component 20 is rotatably connected to the filter bracket 30, and the upper end of the cylindrical filter component 20 is rotatably engaged in the limiting groove, which is defined by the first clamping protrusion 71 on the radial inner side of the connecting frame 70 and the filter bracket 30. Specifically, the connecting frame 70 includes an annular connecting body, a first clamping protrusion 71 inside the connecting body, and a second clamping protrusion 72 on the outer peripheral surface of the connecting body. Among them, the first clamping protrusion 71 extends downward along the axial direction of the connecting body, the bottom of the first clamping protrusion 71 exceeds the bottom wall of the connecting body, and the outer peripheral surface of the first clamping protrusion 71 cooperates with the inner peripheral surface of the filter bracket 30 to define the limiting groove.

[0064] According to some embodiments of the present invention, Figure 2 As shown, the filter assembly 100 further includes: a lifting cup 40, wherein the lifting cup 40 can also filter food residues, thereby further improving the filtering times of the filter assembly 100, thereby further improving the filtering effect of the filter assembly 100.

[0065] Specifically, the cup 40 is arranged on the radial inner side of the cup support 50 and is detachably connected to the cup support 50, and the lower end of the cup 40 passes through the connecting hole 11 and extends into the accommodating cavity 21 of the cylindrical filter component 20. It can be understood that the cup 40 is detachably connected to the cylindrical filter assembly 100 and the cup support 50, so that the user can complete the routine maintenance of the filter assembly 100 without complex disassembly of the equipment, which is conducive to the convenience of cleaning and maintenance of the dishwasher by the user, and thus can improve the user experience.

[0066] The dishwasher according to the embodiment of the second aspect of the utility model comprises the filter assembly 100 according to the embodiment of the first aspect of the utility model.

[0067] Specifically, the dishwasher may be a sink dishwasher, a cleaning machine, and a general dishwasher.

[0068] Optional, such as Figure 3 As shown, the filter assembly 100 further includes: a sterilization 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 accommodating chamber 21 .

[0069] During the process of the dishwasher rinsing the dishes in a cycle, water flows in from one side of the opening of the accommodating chamber 21 and then flows out from the other side of the accommodating 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 accommodating 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 arranging the sterilizing element 60, the number of bacteria breeding below the filter bracket 30 can be reduced.

[0070] 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.
