[0042] Embodiment 1

[0043] like Figures 1 to 7 As shown, Figure 1 It is a schematic diagram of the three-dimensional structure of the inner cylinder assembly described in the first embodiment of the present invention.

[0044] Definition of axial symmetry: If a figure is folded along a straight line and it can overlap with another figure, the two figures are said to be axially symmetrical.

[0045] Definition of central symmetry: If a figure can overlap with another figure after being rotated 180 degrees around a certain point, then the two figures are said to form central symmetry.

[0046] like Figure 1 As shown, an embodiment of the present invention provides an inner drum assembly, which is used in a washing machine. Figures 1 to 3 , Figure 5As shown, the inner cylinder assembly includes an inner cylinder 200 and a lifting rib 100, and the lifting rib 100 is clamped and fixed on the inner cylinder 200, thereby simplifying the installation process of the lifting rib 100 and reducing the production cost of the inner cylinder assembly.

[0047] The inner drum assembly is applied to a washing machine, and the lifting ribs 100 are mounted on the inner drum 200, which is simple to operate and takes little time, and can effectively improve the assembly efficiency of the inner drum assembly, thereby also improving the assembly efficiency of the washing machine.

[0048] It can be, for example Figure 1 As shown, the lifting rib 100 is arranged to be fixed on the side wall of the inner cylinder 200; or it can be that the lifting rib 100 is arranged to be fixed on the bottom wall of the inner cylinder 200; or it can be that the lifting rib 100 is arranged to be fixed on the side wall of the inner cylinder 200 and the bottom wall of the inner cylinder 200 respectively; all of the above can achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of the present application.

[0049] In an exemplary embodiment, one of the lifting rib 100 and the inner cylinder 200 has a combined structure, and the other has a matching structure. It can be that the lifting rib 100 has a combined structure and the inner cylinder 200 has a matching structure; or it can be that the lifting rib 100 has a matching structure and the inner cylinder 200 has a combined structure; all of the above can achieve the purpose of this application, and their purpose does not deviate from the design concept of the present invention, and will not be repeated here, and all should belong to the protection scope of this application.

[0050] The following is a detailed description of the "lifting rib 100 has a combined structure, and the inner tube 200 has a matching structure" as an example. The technical solution of "the lifting rib 100 has a matching structure, and the inner tube 200 has a combined structure" can be obtained by a person skilled in the art through a simple structural transformation, and this application will not repeat it here.

[0051] Among them, Figures 2 to 6 As shown, the combined structure is configured to include a positioning portion and a limiting portion, the matching structure is configured to include a positioning matching portion and a limiting matching portion, the positioning portion is configured to be clamped on the positioning matching portion, and the limiting portion is configured to cooperate with the limiting matching portion, so as to prevent the positioning portion and the positioning matching portion from being disengaged from each other, thereby avoiding the problem that the lifting rib 100 is disengaged from the inner cylinder 200 and the lifting rib 100 falls off the inner cylinder 200.

[0052] In an exemplary embodiment, if Figure 2 , Figure 4 and Figure 6 As shown, the matching structure is set as a matching hole. Among them, the matching hole (see Figure 4) is configured to include a positioning section (labeled as 270) and a passing section (labeled as 280), the positioning matching portion is the positioning section in this application, and the limiting matching portion is the passing section in this application. When the lifting rib 100 is installed on the inner cylinder 200, the positioning portion is extended into the passing section, and then the lifting rib 100 is pushed from the passing section to the positioning section, so that the positioning portion passes through the passing section and extends into the positioning section and is clamped on the positioning section. At this time, the limiting portion extends into the passing section and presses against the hole wall of the passing section that is opposite to the positioning section. The limiting portion cannot move back to the positioning section, so the positioning portion cannot escape from the positioning section and then reverse back to the passing section, so the lifting rib 100 can remain stably clamped on the inner cylinder 200.

[0053] In an exemplary embodiment, if Figure 2 , Figure 5 and Figure 6 As shown, the positioning portion can be configured as a hook, which extends from the passing section into the positioning section and is clamped on the outer end surface of the positioning section in a hooking manner. The width of the passing section may be greater than the width of the positioning section, and the hook head of the hook is set to the left or right. The width of the hook head is smaller than the passing section and larger than the positioning section. The width of the connecting neck of the hook is slightly smaller than the width of the positioning section. The hook head of the hook passes through the passing section. When the connecting neck of the hook moves from the passing section to the positioning section, the hook head of the hook is clamped on the positioning section and is restricted by the hook head. The hook will not fall out of the positioning section.

[0054] Of course, the positioning portion can also be an annular slot, the slot extends from the through section into the positioning section, the mouth walls on both sides of the positioning section protrude inward relative to the mouth walls on both sides of the through section, and the slot is stuck on the mouth walls on both sides of the positioning section, which can also achieve the purpose of this application. Its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all belong to the protection scope of this application. For example, the slot can also be set as a C-shaped slot.

[0055] In an exemplary embodiment, if Figure 2 , Figure 5 and Figure 6 As shown, the limiting portion is arranged as a stop boss, and a side of the stop boss facing the positioning section has a guiding inclined surface, which is more conducive to the stop boss entering the passing section.

[0056] In an exemplary embodiment, if Figure 5 As shown, the matching hole is set as a countersunk hole, the positioning section and the through section together form an L-shaped structure, the positioning portion is clamped on the bottom wall of the countersunk hole at the positioning section, and the side of the stop boss facing away from the positioning section is pressed against the hole wall of the countersunk hole at the through section facing away from the positioning section, thereby keeping the lifting rib 100 stably clamped on the inner cylinder 200. The side of the stop boss facing the positioning section is set as a guide slope (such as Figure 6As shown in the figure, by setting the guiding inclined surface, it is more conducive to realize that the stop boss slides into the passing section. It can be that the mouth wall of the passing section is concave toward the lifting rib relative to the mouth wall of the positioning section, and the connection position of the mouth wall of the passing section and the mouth wall of the positioning section is connected by a smooth transition curved surface 290, so that the hook head of the hook can slide more smoothly along the smooth transition curved surface 290 to the mouth wall of the positioning section in the passing section, and finally the hook head of the hook is more tightly stuck on the mouth wall of the positioning section, and the gap between the lifting rib and the inner tube is smaller. For example, the stop boss is in the shape of a right triangle.

[0057] In an exemplary embodiment, the combined structure is configured to include a first combined structure and a second combined structure, the first combined structure and the second combined structure are configured to be centrally symmetrical with each other, and the first combined structure and the second combined structure are configured to selectively cooperate with the matching hole, so that no matter whether the lifting rib 100 is installed in the forward direction or the reverse direction (i.e., held forward or reversed), it can be installed on the inner drum 200, that is, the lifting rib 100 does not need to distinguish between the forward and reverse directions when installed, which saves the time for adjusting the lifting rib 100, and can also improve the assembly efficiency of the inner drum assembly, thereby achieving the purpose of improving the assembly efficiency of the washing machine.

[0058] Among them, the matching hole can be set as one (not shown in this scheme), the first combined structure includes a first positioning portion and a first limiting portion, and the second combined structure includes a fourth positioning portion and a fourth limiting portion (not shown in this scheme, can be combined with Figure 2 , Figure 3 and Figure 5 for better understanding).

[0059] Of course, the matching holes may also include a plurality of holes, such as in an exemplary embodiment. Figure 2 As shown, the first combined structure 150 is configured to include a first sub-positioning portion 101 and a third sub-positioning portion 103. The first combined structure 150 is configured to also include a first sub-limiting portion 110 and a third sub-limiting portion 130. Wherein, in the front-to-back direction (i.e., the length direction of the lifting rib 100), from front to back, the first sub-positioning portion 101 is located in front of the first sub-limiting portion 110, the first sub-limiting portion 110 is located in front of the third sub-positioning portion 103, and the third sub-positioning portion 103 is located in front of the third sub-limiting portion 130. In the front-to-back direction, the first sub-positioning portion 101 and the first sub-limiting portion 110 are located in the same column, and the third sub-positioning portion 103 and the third sub-limiting portion 130 are located in the same column. In the left-right direction, the first sub-positioning portion 101 and the first sub-limiting portion 110 are located on the left side of the third sub-positioning portion 103 and the third sub-limiting portion 130.

[0060] like Figure 2As shown, the second combined structure 160 is configured to include a second sub-positioning portion 102 and a fourth sub-positioning portion 104. The second combined structure 160 is configured to also include a second sub-limiting portion 120 and a fourth sub-limiting portion 140. Wherein, in the front-to-back direction (i.e., the length direction of the lifting rib 100), from front to back, the second sub-limiting portion 120, the second sub-positioning portion 102, the fourth sub-limiting portion 140 and the fourth sub-positioning portion 104 are sequentially arranged at intervals. In the front-to-back direction, the second sub-limiting portion 120 and the second sub-positioning portion 102 are located in the same column, and the fourth sub-limiting portion 140 and the fourth sub-positioning portion 104 are located in the same column. In the left-right direction, the second sub-limiting portion 120 and the second sub-positioning portion 102 are located on the left side of the fourth sub-limiting portion 140 and the fourth sub-positioning portion 104.

[0061] The positioning part is configured to include the first sub-positioning part 101, the second sub-positioning part 102, the third sub-positioning part 103 and the fourth sub-positioning part 104 mentioned above. The limiting part is configured to include the first sub-limiting part 110, the second sub-limiting part 120, the third sub-limiting part 130 and the fourth sub-limiting part 140 mentioned above.

[0062] In the front-to-back direction, the first sub-positioning portion 101, the first sub-limiting portion 110, the second sub-limiting portion 120 and the second sub-positioning portion 102 are located in the same row, and the third sub-positioning portion 103, the third sub-limiting portion 130, the fourth sub-limiting portion 140 and the fourth sub-positioning portion 104 are located in the same row. The hook formed by the first sub-positioning portion 101 and the hook formed by the second sub-positioning portion 102 are both arranged to face right, and the guiding slope of the first sub-limiting portion 110 and the guiding slope of the second sub-limiting portion 120 are arranged opposite to each other in the front-to-back direction; the hook formed by the third sub-positioning portion 103 and the hook formed by the fourth sub-positioning portion 104 are both arranged to face left, and the guiding slope of the third sub-limiting portion 130 and the guiding slope of the fourth sub-limiting portion 140 are arranged opposite to each other in the front-to-back direction. Among them, the first sub-positioning portion 101 and the fourth sub-positioning portion 104 are centrally symmetrically arranged, and the second sub-positioning portion 102 and the third sub-positioning portion 103 are centrally symmetrically arranged; the first sub-limiting portion 110 and the fourth sub-limiting portion 140 are centrally symmetrically arranged, and the second sub-limiting portion 120 and the third sub-limiting portion 130 are centrally symmetrically arranged.

[0063] In an exemplary embodiment, if Figure 3As shown, the matching holes are arranged to include a first matching hole 210 and a third matching hole 230. The first matching hole 210 is arranged to correspond to the first sub-positioning portion 101 and the first sub-limiting portion 110, and the third matching hole 230 is arranged to correspond to the third sub-positioning portion 103 and the third sub-limiting portion 130. The front side of the first matching hole 210 is provided with a positioning section, and the rear side is provided with a passing section. The front side of the third matching hole 230 is provided with a positioning section, and the rear side is provided with a passing section. Moreover, the first matching hole 210 and the third matching hole 230 are arranged symmetrically. The first combined structure 150 and the second combined structure 160 are selected to match the first matching hole 210 and the third matching hole 230. That is, when the first combination structure 150 cooperates with the first matching hole 210 and the third matching hole 230, the second combination structure 160 does not cooperate with the first matching hole 210 and the third matching hole 230; when the second combination structure 160 cooperates with the first matching hole 210 and the third matching hole 230, the first combination structure 160 does not cooperate with the first matching hole 210 and the third matching hole 230.

[0064] It can be, for example Figure 5 As shown, when the lifting rib 100 is properly installed on the inner cylinder 200, the first sub-positioning portion 101 and the first sub-limiting portion 110 cooperate with the positioning section of the first matching hole 210 and the passing section of the first matching hole 210, and the third sub-positioning portion 103 and the third sub-limiting portion 130 cooperate with the positioning section of the third matching hole 230 and the passing section of the third matching hole 230.

[0065] Alternatively, when the lifting rib 100 is reversely installed on the inner cylinder 200 (not shown in the figure), the fourth sub-positioning portion 104 and the fourth sub-limiting portion 140 cooperate with the positioning section of the first matching hole 210 and the passing section of the first matching hole 210, and the second sub-positioning portion 102 and the second sub-limiting portion 120 cooperate with the positioning section of the third matching hole 230 and the passing section of the third matching hole 230.

[0066] In an exemplary embodiment, if Figure 2 and Figure 5 As shown, the first assembly structure 150 is located in front of the second assembly structure 160 . In the left-right direction, the second sub-positioning portion 102 and the third sub-positioning portion 103 are in the same row, and the second sub-positioning portion 102 is located on the left side of the third sub-positioning portion 103 .

[0067] In one example, if Figure 2 , Figure 3 and Figure 5As shown, the inner cylinder 200 is further provided with a second matching hole 220 and a fourth matching hole 240, wherein the second matching hole 220 is provided corresponding to the second sub-positioning portion 102, and the fourth matching hole 240 is provided corresponding to the fourth sub-positioning portion 104. The second matching hole 220 includes a positioning section located at the front side and a passing section located at the rear side, and the fourth matching hole 240 also includes a positioning section located at the front side and a passing section located at the rear side.

[0068] It can be, for example Figure 5 As shown, when the lifting rib 100 is properly installed on the inner cylinder 200, the second sub-positioning portion 102 passes through the passing section of the second matching hole 220 and is stuck in the positioning section of the second matching hole 220. The second sub-limiting portion 120 is located in front of the second sub-positioning portion 102 and is located on the outside of the second matching hole 220 and cannot abut on the passing section of the second matching hole 220; the fourth sub-positioning portion 104 passes through the passing section of the fourth matching hole 240 and is stuck in the positioning section of the fourth matching hole 240. The fourth sub-limiting portion 140 is located in front of the fourth sub-positioning portion 104 and is located on the outside of the fourth matching hole 240 and cannot abut on the passing section of the fourth matching hole 240.

[0069] Alternatively, when the lifting rib 100 is reversely installed on the inner tube 200 (not shown in the figure), the third sub-positioning portion 103 passes through the passing section of the second matching hole 220 and is stuck in the positioning section of the second matching hole 220, and the third sub-limiting portion 130 is located in front of the third sub-positioning portion 103 and is located on the outside of the second matching hole 220 and cannot abut on the passing section of the second matching hole 220; the first sub-positioning portion 101 passes through the passing section of the fourth matching hole 240 and is stuck in the positioning section of the fourth matching hole 240, and the first sub-limiting portion 110 is located in front of the first sub-positioning portion 101 and is located on the outside of the fourth matching hole 240 and cannot abut on the passing section of the fourth matching hole 240.

[0070] The second matching hole 220 can be set as a long strip avoidance hole, and the fourth matching hole 240 can be set as a long strip avoidance hole, and the avoidance hole can be a waist-shaped hole or a rectangular hole, etc. (not shown in the figure); the second matching hole 220 can also be set as a long strip avoidance hole, and the fourth matching hole 240 can also be set to include a positioning section located on the front side and a passing section located on the rear side, and the avoidance hole can be a waist-shaped hole or a rectangular hole, etc. (not shown in the figure); the second matching hole 220 can also be set to include a positioning section located on the front side and a passing section located on the rear side, and the fourth matching hole 240 can also be set as a long strip avoidance hole, and the avoidance hole can be a waist-shaped hole or a rectangular hole, etc. (not shown in the figure); all of the above can achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all belong to the protection scope of the present application.

[0071] In one example, if Figure 2 and Figure 5 As shown, a fifth sub-positioning portion 105 may also be provided on the lifting rib 100. In the front-to-back direction: the fifth sub-positioning portion 105 and the third sub-positioning portion 103, the third sub-limiting portion 130, the fourth sub-limiting portion 140 and the fourth sub-positioning portion 104 are all arranged in the same column; in the left-right direction: the fifth sub-positioning portion 105 and the first sub-positioning portion 101 are arranged in the same row, and the fifth sub-positioning portion 105 is located on the right side of the first sub-positioning portion 101, that is: the fifth sub-positioning portion 105, the third sub-positioning portion 103, the third sub-limiting portion 130, the fourth sub-limiting portion 140 and the fourth sub-positioning portion 104 are arranged in sequence from front to back. Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the inner cylinder 200 is further provided with a fifth matching hole 250, and the fifth matching hole 250 is arranged to correspond to the fifth sub-positioning portion 105. The fifth matching hole 250 is also arranged to include a positioning section located at the front side and a passing section located at the rear side.

[0072] In one example, if Figure 2 and Figure 5 As shown, the lifting rib 100 is also provided with a sixth sub-positioning portion 106. In the front-to-back direction: the sixth sub-positioning portion 106 and the second sub-positioning portion 102, the second sub-limiting portion 120, the first sub-limiting portion 110 and the first sub-positioning portion 101 are arranged in the same column; in the left-right direction: the sixth sub-positioning portion 106 and the fourth sub-positioning portion 104 are arranged in the same row, and the sixth sub-positioning portion 106 is located on the left side of the fourth sub-positioning portion 104; that is: the sixth sub-positioning portion 106, the second sub-positioning portion 102, the second sub-limiting portion 120, the first sub-limiting portion 110 and the first sub-positioning portion 101 are arranged in sequence from back to front. Figure 2 , Figure 3 and Figure 5 As shown, the inner cylinder 200 is further provided with a sixth matching hole 260, which is arranged to correspond to the sixth sub-positioning portion 106. The sixth matching hole 260 is also arranged to include a positioning section located at the front side and a passing section located at the rear side.

[0073] For example, the fifth sub-positioning portion 105 and the sixth sub-positioning portion 106 are centrally symmetrically arranged, and the fifth matching hole 250 and the sixth matching hole 260 are also centrally symmetrically arranged.

[0074] It can be, for example Figure 5 As shown, when the lifting rib 100 is properly installed on the inner tube 200, the fifth sub-positioning portion 105 passes through the passing section of the fifth matching hole 250 and is stuck in the positioning section of the fifth matching hole 250, and the sixth sub-positioning portion 106 passes through the passing section of the sixth matching hole 260 and is stuck in the positioning section of the sixth matching hole 260.

[0075] Alternatively, when the lifting rib 100 is reversely installed on the inner tube 200 (not shown in the figure), the fifth sub-positioning portion 105 passes through the passing section of the sixth matching hole 260 and is stuck in the positioning section of the sixth matching hole 260, and the sixth sub-positioning portion 106 passes through the passing section of the fifth matching hole 250 and is stuck in the positioning section of the fifth matching hole 250.

[0076] In one example, if Figure 3 As shown, the first matching hole 210, the second matching hole 220 and the sixth matching hole 260 have the same structure, and the third matching hole 230, the fourth matching hole 240 and the fifth matching hole 250 have the same structure. The first matching hole 210 and the fifth matching hole 250 are arranged axially symmetrically, the second matching hole 220 and the third matching hole 230 are arranged axially symmetrically, and the sixth matching hole 260 and the fourth matching hole 240 are arranged axially symmetrically. Corresponding: Figure 2 As shown, the first sub-positioning portion 101, the second sub-positioning portion 102 and the sixth sub-positioning portion 106 have the same structure, and the third sub-positioning portion 103, the fourth sub-positioning portion 104 and the fifth sub-positioning portion 105 have the same structure. The first sub-positioning portion 101 and the fifth sub-positioning portion 105 are arranged axially symmetrically, the second sub-positioning portion 102 and the third sub-positioning portion 103 are arranged axially symmetrically, and the sixth sub-positioning portion 106 and the fourth sub-positioning portion 104 are arranged axially symmetrically. This solution can better ensure that the lifting rib 100 is firmly fixed on the inner cylinder 200 through multi-point positioning, and the lifting rib 100 will not be warped at various positions.

[0077] In the present application: the positioning sections on the first mating hole 210, the second mating hole 220, the third mating hole 230, the fourth mating hole 240, the fifth mating hole 250 and the sixth mating hole 260 have the same structure and are all marked as positioning sections 270 in the accompanying drawings; the passing sections on the first mating hole 210, the second mating hole 220, the third mating hole 230, the fourth mating hole 240, the fifth mating hole 250 and the sixth mating hole 260 have the same structure and are all marked as passing sections 280 in the accompanying drawings.

[0080] The second sub-positioning portion 102 passes through the through section of the second matching hole 220 and is stuck in the positioning section of the second matching hole 220. The second sub-positioning portion 120 is located outside the second matching hole 220 because it is located in front of the second sub-positioning portion 102 and cannot abut against the through section of the second matching hole 220. The fourth sub-positioning portion 104 passes through the through section of the fourth matching hole 240 and is stuck in the positioning section of the fourth matching hole 240. The fourth sub-positioning portion 140 is located outside the fourth matching hole 240 because it is located in front of the fourth sub-positioning portion 104 and cannot abut against the through section of the fourth matching hole 240.

[0081] The fifth sub-positioning portion 105 passes through the passing section of the fifth matching hole 250 and is stuck in the positioning section of the fifth matching hole 250 . The sixth sub-positioning portion 106 passes through the passing section of the sixth matching hole 260 and is stuck in the positioning section of the sixth matching hole 260 .

[0084] The third sub-positioning portion 103 passes through the through section of the second matching hole 220 and is stuck in the positioning section of the second matching hole 220. The third sub-positioning portion 130 is located in front of the third sub-positioning portion 103 and is located outside the second matching hole 220 and cannot abut against the through section of the second matching hole 220. The first sub-positioning portion 101 passes through the through section of the fourth matching hole 240 and is stuck in the positioning section of the fourth matching hole 240. The first sub-positioning portion 110 is located in front of the first sub-positioning portion 101 and is located outside the fourth matching hole 240 and cannot abut against the through section of the fourth matching hole 240.

[0085] The fifth sub-positioning portion 105 passes through the passing section of the sixth matching hole 260 and is stuck in the positioning section of the sixth matching hole 260 . The sixth sub-positioning portion 106 passes through the passing section of the fifth matching hole 250 and is stuck in the positioning section of the fifth matching hole 250 .
