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.

[0030] 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.

[0031] like Figure 1-9 As shown, a filter according to an embodiment of the present invention includes a main frame 1, a cylindrical filter section 2, a plurality of first ball bearings 3, a plurality of second ball bearings 4, and a lifting cup 5.

[0032] The main frame 1 includes an upper frame 11 and a lower frame 12, which are detachably connected. Preferably, the upper frame 11 and the lower frame 12 are snap-fitted together to improve assembly and disassembly efficiency.

[0033] The cylindrical filter screen 2 has mesh openings on its side wall. The two ends of the cylindrical filter section 2 are rotatably connected to the upper frame 11 and the lower frame 12 respectively. The cylindrical filter section 2 is used to retain small residues inside the cylindrical filter section 2 to prevent small residues from being sucked into the washing pump and thus avoid affecting the washing effect.

[0034] The first ball bearing 3 is disposed between the upper axial end of the cylindrical filter section 2 and the upper frame 11, and the second ball bearing 4 is disposed between the lower axial end of the cylindrical filter section 2 and the lower frame 12. The first ball bearing 3 and the second ball bearing 4 are configured to reduce the friction between the cylindrical filter section 2 and the upper frame 11 and the lower frame 12, thereby improving the flexibility of rotation and avoiding rotation jamming due to wear.

[0035] The lifting cup 5 is coaxially mounted inside the cylindrical filter section 2. When the lifting cup 5 is installed in place, its upper part engages with the upper frame 11, and its lower end abuts against the lower frame 12. The lifting cup 5 has multiple perforated holes 51, the size of which is larger than the size of the mesh of the cylindrical filter section 2. The lifting cup 5 performs the first coarse filtration of the residue, retaining large pieces of residue in the lifting cup 5 to prevent clogging of the mesh of the cylindrical filter section 2. The cylindrical filter section 2 then performs the second filtration to prevent small residues from being sucked into the washing pump, thereby improving the washing effect.

[0036] Because the cylindrical filter section 2 can rotate flexibly, the residue does not accumulate in one place, thus improving the smooth flow of washing water.

[0037] When it is necessary to clean the mesh of the cylindrical filter section 2, remove the cup 5, 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.

[0038] like Figure 2 , 3 As shown in Figures 5 and 8, in a preferred embodiment of this utility model, a first annular portion 111 is provided on the inner edge of the upper frame 11, as shown in Figures 5 and 8. Figure 2 , 4 As shown in Figures 5 and 7, a second annular portion 121 is provided on the inner edge of the bottom of the lower frame 12. The two ends of the cylindrical filter portion 2 can be rotatably inserted into the first annular portion 111 and the second annular portion 121 respectively, so as to realize the rotatable installation of the cylindrical filter portion 2.

[0039] The first ball bearing 3 is located between the first annular portion 111 and the upper axial end of the cylindrical filter portion 2, and the second ball bearing 4 is located between the second annular portion 121 and the lower axial end of the cylindrical filter portion 2.

[0040] like Figure 3 , 6 As shown, in a preferred embodiment of the present invention, a plurality of first grooves 21 matching the first balls 3 are spaced apart at one axial end of the cylindrical filter section 2. The first balls 3 are rotatably disposed in the first grooves 21 and abut against the first annular portion 111. When the cylindrical filter section 2 rotates, the first balls 3 rotate within the first grooves 21 and revolve around the first annular portion 111.

[0041] like Figure 3 , 8 As shown, in a preferred embodiment of the present invention, the lower end of the first annular portion 111 is provided with a first annular groove 1111 with the opening facing downward. The upper end of the cylindrical filter portion 2 is inserted into the first annular groove 1111. The first ball 3 abuts against the top wall of the first annular groove 1111, thereby limiting the first ball 3 and preventing the first ball 3 from rolling out of the first groove 21.

[0042] Alternatively, the upper end of the cylindrical filter section 2 is provided with an upward-opening first annular groove, the first annular groove is rotatably inserted into the lower end of the first annular section 111, and the first groove 21 is located on the bottom wall inside the first annular groove.

[0043] like Figure 3 As shown, in a preferred embodiment of the present invention, a second annular groove 1112 is provided on the top wall of the first annular groove 1111. The cross-section of the second annular groove 1112 is an arc shape adapted to the first ball 3. The first ball 3 abuts against the inner wall of the second annular groove 1112. When the cylindrical filter part 2 rotates, the first ball 3 revolves along the second annular groove 1112. The second annular groove 1112 and the first groove 21 together limit the first ball 3 to prevent the first ball 3 from falling off when rotating.

[0044] like Figure 4 , 7 As shown, in a preferred embodiment of this utility model, the second annular portion 121 is provided with a second groove 1211 that matches the second ball 4 at intervals. The second ball 4 is rotatably disposed in the second groove 1211, and the other axial end of the cylindrical filter portion 2 abuts against the second ball 4. When the cylindrical filter portion 2 rotates, the lower end of the cylindrical filter portion 2 drives the second ball 4 to rotate within the second groove 1211, thereby reducing the rotational friction of the cylindrical filter portion 2.

[0045] like Figure 9 As shown, in a preferred embodiment of this utility model, the lower end of the cylindrical filter section 2 is provided with a downward-facing third annular groove 22, and the top wall of the third annular groove 22 abuts against the second ball bearing 4. The third annular groove 22 and the second groove 1211 together limit the second ball bearing 4 to prevent the second ball bearing 4 from falling off when rotating.

[0046] like Figure 6 As 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 arc-shaped ribs 23, the first arc-shaped ribs 23 and the first ball 3 are arranged alternately, and the first arc-shaped ribs 23 are configured to limit the first ball 3 and prevent the first ball 3 from rolling out of the first groove 21.

[0047] The upper end of the second annular portion 121 has a plurality of second arc-shaped ribs 1212, which are arranged alternately with the second ball 4. The second arc-shaped ribs 1212 are configured to limit the second ball 4 and prevent the second ball 4 from rolling out of the second groove 1211.

[0048] like Figure 7 , 8 As shown, according to one embodiment of the present invention, the lower end of the side wall of the upper frame 11 is provided with a plurality of first buckles 112, and the upper end of the lower frame 12 is provided with a first locking hole 122 corresponding to the first buckles 112. The first buckles 112 engage with the first locking holes 122, thereby facilitating the assembly and disassembly of the upper frame 11 and the lower frame 12 and improving assembly and maintenance efficiency. 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 buckles 112 engage with or disassemble from the first locking holes 122, so as to facilitate engagement or disassembly.

[0049] Of course, the first locking hole 122 is not limited to being located on the lower frame 12. For example, multiple first locking holes 122 are provided at the lower end of the side wall of the upper frame 11, and a first buckle 112 is provided at the upper end of the lower frame 12 corresponding to the first locking holes 122. Those skilled in the art can select the position of the first locking hole 12 according to actual needs.
