[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0034] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0035] like Figure 1-10 As shown, a filter according to an embodiment of the present invention includes a main frame 1, a cylindrical filter section 2, and a lifting cup 3.

[0036] The main frame 1 includes an upper frame 11 and a lower frame 12, which are snapped together.

[0037] The two ends of the cylindrical filter section 2 are rotatably connected to the upper frame 11 and the lower frame 12 respectively. The side wall of the cylindrical filter section 2 is provided with multiple mesh holes. The cup 3 is set inside the cylindrical filter section 2 and is detachably connected to the main frame 1. The cup 3 has multiple hollow holes 31. The size of the hollow holes 31 is larger than the size of the mesh holes. The cup 3 performs the first coarse filtration of the residue to leave large pieces of residue in the cup 3 to prevent clogging of the mesh holes of the cylindrical filter section 2. The cylindrical filter section 2 performs the second filtration to prevent small residues from being sucked into the washing pump and to avoid affecting the washing effect.

[0038] When too much residue accumulates in the cup 3, the cup 3 can be removed and the residue poured out for easy cleaning. Since the cylindrical filter section 2 is rotatable, when the side of the cylindrical filter section 2 opposite to the water inlet is full of residue and water absorption is not smooth, the cylindrical filter section 2 can be rotated to prevent the residue from accumulating in one place and improve the smooth flow of washing water.

[0039] When it is necessary to clean the mesh of the cylindrical filter section 2, remove the cup 3, separate the upper frame 11 from the lower frame 12, and then remove the cylindrical filter section 2. There is no need to remove the entire filter from the dishwasher, which makes it easy to clean the cylindrical filter section 2.

[0040] like Figure 1 , 2 As shown in Figures 5, 6, and 8, in a preferred embodiment of this utility model, a first annular portion 111 is provided inside the upper frame 11. The lower end of the first annular portion 111 has a downward-opening first annular groove 1111. The upper end of the cylindrical filter portion 2 is rotatably inserted into the first annular groove 1111. The cross-section of the first annular groove 1111 is larger than the cross-section of the upper end of the cylindrical filter portion 2, allowing the upper end of the cylindrical filter portion 2 to rotate freely within the first annular groove 1111.

[0041] Alternatively, the upper end of the cylindrical filter section 2 is provided with an upward-opening first annular groove, and the lower end of the first annular part 111 is an annular protrusion. The cylindrical filter section 2 can be rotatably inserted into the annular protrusion at the lower end of the first annular part 111 through the first annular groove.

[0042] The outer edge of the first annular portion 111 is fixedly connected to the lower part of the inner wall of the upper frame 11. Preferably, the first annular portion 111 and the upper frame 11 are integrally formed to improve the overall structural strength.

[0043] like Figure 7As shown, in a preferred embodiment of the present invention, the upper end of the cylindrical filter section 2 is provided with a plurality of first protrusions 22 at intervals. The first protrusions 22 are in frictional contact with the top wall of the first annular groove 1111, thereby reducing the friction surface between the upper end of the cylindrical filter section 2 and the top wall of the first annular groove 1111, and thus reducing the friction force; and / or the inner wall of the upper end of the cylindrical filter section 2 is provided with a plurality of first ribs 23 at intervals. The first ribs 23 are in frictional contact with the side wall of the first annular groove 1111, thereby reducing the friction surface between the inner side wall of the upper end of the cylindrical filter section 2 and the side wall of the first annular groove 1111, and thus reducing the friction force.

[0044] like Figure 2 , 4 As shown in Figures 5 and 6, in a preferred embodiment of this utility model, a second annular portion 121 is provided inside the lower frame 12. The upper end of the second annular portion 121 is provided with an annular rib 1211, and the lower end of the cylindrical filter portion 2 is provided with a second annular groove 21. The second annular groove 21 and the annular rib 1211 are rotatably inserted into each other. The second annular portion 121 and the first annular portion 111 together limit the axial movement of the cylindrical filter portion 2 to prevent the axial movement of the cylindrical filter portion 2 from causing filtration failure.

[0045] Of course, the connection method between the cylindrical filter section 2 and the second annular section 121 is not limited to the above embodiment. For example, the lower end of the cylindrical filter section 2 is provided with an annular rib, and the upper end of the second annular section 121 is provided with a second annular groove. The second annular groove and the annular rib can be rotatably inserted into each other.

[0046] like Figure 6 , 10 As shown, in a preferred embodiment of the present invention, a plurality of second protrusions 1215 are provided at intervals on the upper end of the annular rib 1211. The second protrusions 1215 are in frictional contact with the top wall of the second annular groove 21, thereby reducing the friction between the top wall of the second annular groove 21 and the annular rib 1211, and thus facilitating the rotation of the cylindrical filter section 2.

[0047] Of course, the methods for reducing friction are not limited to the above-described embodiments. For example, the inner wall of the second annular groove 21 is provided with a plurality of second ribs, and the second ribs are in frictional contact with the side wall of the annular rib 1211. The second protrusion 1215 and the second rib are both used to reduce the friction between the inner wall of the second annular groove 21 and the annular rib 1211 and to reduce wear, thereby facilitating the rotation of the cylindrical filter section 2 and extending the service life of the cylindrical filter section 2.

[0048] The outer edge of the second annular portion 121 is fixedly connected to the lower end of the inner wall of the lower frame 12. Preferably, the second annular portion 121 and the lower frame 12 are integrally formed to improve the structural strength of the lower frame 12.

[0049] like Figure 8As shown, in a preferred embodiment of this utility model, the lower end of the outer side wall of the upper frame 11 is provided with one of a plurality of first buckles 112 and first holes 122, and the upper end of the lower frame 12 is provided with the other of the first buckles 112 and first holes 122. The first buckles 112 and the first holes 122 are engaged, so as to realize the convenient disassembly and assembly of the upper frame 11 and the lower frame 12, and improve the assembly and maintenance efficiency.

[0050] The upper frame 11 and / or the lower frame 12 are made of elastic material, so that the upper frame 11 and / or the lower frame 12 can undergo a certain deformation when the first buckle 112 is engaged or disassembled from the first buckle hole 122, so as to facilitate engagement or disassembly.

[0051] like Figure 5 , 6 As shown in Figure 8, in a preferred embodiment of this utility model, the lower end of the outer side wall of the upper frame 11 is provided with at least one of a boss 113 and a notch 123, and the upper end of the lower frame 12 is provided with the other of a boss 113 and a notch 123. When the boss 113 is inserted into the notch 123, the first buckle 112 is aligned with the first buckle hole 122.

[0052] The boss 113 and the notch 123 work together to limit the upper frame 11 and the lower frame 12 in one axial direction. The first buckle 112 and the first locking hole 122 work together to limit the upper frame 11 and the lower frame 12 in another axial direction, thereby locking the connection between the upper frame 11 and the lower frame 12.

[0053] like Figure 1 , 2 As shown in Figures 5 and 7, in a preferred embodiment of this utility model, two handles 32 are symmetrically arranged at the upper end of the cup 3. The free end of the handle 32 extends outward and is provided with a circular part 322. The outer side of the circular part 322 is provided with a groove 3221. The upper end of the upper frame 11 is symmetrically provided with a relief groove 115. When the cup 3 is installed in place, the circular part 322 is located in the relief groove 115, reducing the space occupied by the circular part 322, so that the handle 32 and the upper frame 11 are integrated, improving the aesthetics.

[0054] like Figure 1 , 2As shown in Figures 5 and 7, in a preferred embodiment of this utility model, both the cup holder 3 and the handle 32 are made of elastic plastic. The handle 32 is provided with one of a second buckle 321 and a second locking hole 114, and the upper frame 11 is provided with the other of a second buckle 321 and a second locking hole 114. The second buckle 321 engages with the second locking hole 114. For example, when installing the cup holder 3, pressing the cup holder 3 downwards causes the two handles 32 to retract radially during the pressing process. When the second buckle 321 and the second locking hole 114 are aligned, the two handles 32 return to their radial position, allowing the second buckle 321 to be inserted into the second locking hole 114.

[0055] After the second buckle 321 engages with the second buckle hole 114, the cup 3 cannot move axially or radially, nor can it rotate, thus fixing the cup 3.

[0056] like Figure 2 , 5 As shown in Figure 7, in a preferred embodiment of the present invention, the inner edge of the second annular portion 121 is provided with a plurality of spaced-apart support columns 1212, the upper end of the support column 1212 is provided with a third annular portion 1213, and the lower end of the cup 3 is provided with a plurality of spaced-apart limiting ribs 33.

[0057] When the cup 3 is installed in place, the upper end of the cup 3 is engaged with the second buckle 321 and the second buckle hole 114, and the lower end of the cup 3 abuts against the third annular part 1213, so that the cup 3 cannot axially shake. Furthermore, the limiting rib 33 abuts against the inner edge surface of the third annular part 1213, thereby radially limiting the cup 3 and preventing the cup 3 from horizontally shaking.

[0058] When it is necessary to disassemble the cup 3, hold the two circular parts 322 together with your thumb and forefinger, causing the two handles 32 to retract towards the axis, thereby separating the second buckle 321 from the second locking hole 114. Then, pull the cup 3 upward to remove it. The groove 3221 is used to increase the force point for lifting and prevent the circular parts 322 from slipping off the fingers.

[0059] like Figure 2 , 5 As shown in Figures 7 and 9, the cylindrical filter section 2 includes a cylindrical filter screen, an annular top, an annular bottom, and multiple connecting posts. The lower end of the connecting post is fixedly connected to the annular bottom, and the upper end of the connecting post is fixedly connected to the annular top. The multiple connecting posts are arranged at intervals. One axial end of the cylindrical filter screen is fixedly connected to the annular top, and the other axial end of the cylindrical filter screen is fixedly connected to the annular bottom. The annular top is rotatably inserted into the first annular groove 1111, and the second annular groove 21 is located at the lower end of the annular bottom.

[0060] In a preferred embodiment of this utility model, both the upper frame 11 and the lower frame 12 are provided with multiple hollow holes, and the hollow holes of the lower frame 12 are larger than the hollow holes 31 of the cup 3.

[0061] like Figure 2 As shown, in a preferred embodiment of this utility model, the second annular portion 121 is provided with a plurality of downwardly extending first fastening positions 1214. The first fastening positions 1214 are configured to engage with the second fastening position of the water cup, thereby facilitating the installation and removal of the filter. For example, the first fastening position 1214 is a snap-fit ​​head, and the second fastening position is a slot. During the insertion of the filter into the water cup, the first fastening position 1214 retracts radially. When the filter is fully inserted into the water cup, the first fastening position 1214 elastically resets and engages with the slot, thereby achieving a detachable and fixed filter.

[0062] This invention also provides a dishwasher, including a water cup and the aforementioned filter, the filter being detachably installed inside the water cup. Because of the aforementioned filter, the dishwasher of this invention improves the flow of washing water and facilitates filter cleaning.

[0063] In this embodiment of the invention, the term "multiple" refers to two or more, unless otherwise explicitly defined. The terms "install," "connect," and "fix" should be interpreted broadly. For example, "connect" can mean a fixed connection, a detachable connection, or an integral connection.
