[0037] Example

[0038] <Overall Layout>

[0039] like Figure 1a and Figure 1bAs shown, the drum lifting rib module provided in this embodiment includes a shell and a base, and the shell and the base are connected by a detachable structure, wherein the shell as a whole is an S-shaped structure, including a top, a left side and a right side; the top extends along the S-shaped structure and is connected to the left side and the right side; the left side and the right side are respectively provided on the left and right sides of the top, and the left side and the right side are formed with concave and convex surfaces; an inner cavity is formed inside the shell, and a flow hole connected to the inner cavity is formed on the concave surface. When washing clothes, washing water can pass through the flow hole, reducing the pressure of the lifting rib module to lift the clothes; after the shell is connected to the base, the base can be accommodated in the inner cavity of the shell, so that only the shell can be seen from the outside, and the base does not affect the washing effect and appearance of the shell.

[0040] Preferably, the convex surface has an arc-shaped groove, which protrudes toward the top of the shell. On the one hand, it increases the friction between the shell and the clothes, and on the other hand, it has a certain guiding effect on the washing water, guiding the washing water to both sides of the convex surface, causing the washing water to produce a certain mechanical movement, increasing the impact force of the washing water on the clothes, and thus improving the washing effect of the washing water. In addition, the clothes can be stuck in the arc-shaped groove along at least a part of the convex surface, increasing the lifting height of the clothes by the lifting rib module.

[0041] Preferably, the left and right sides are tilted toward the top as a whole, so that the shell forms a structure that is narrow at the top and wide at the bottom. On the one hand, the shell forms an inner cavity that can accommodate the base. On the other hand, the shell has a certain strength, forming a structure that can lift clothes and ensure the amount of clothes lifted. In addition, it can reduce the space occupied by the lifting rib module.

[0042] Preferably, the shell has a first fixing hole, and correspondingly, the base has a first fixing column, and the first fixing hole and the first fixing column cooperate to fix the shell to the base; specifically, the first fixing hole is vertically oriented and is a stepped hole, including two, and the first fixing column is vertically arranged on the top of the base, also including two; the screw passes through the first fixing hole and is threadedly connected to the first fixing column to achieve a detachable connection between the shell and the base; when the shell is connected to the base, there is a certain amount of empty space at the top of the first fixing hole, and a rubber plug is used to fill the empty space to isolate the screw, thereby preventing the top of the screw from damaging the clothes when washing clothes.

[0043] <Housing>

[0044] like Figure 2a As shown, in the shell structure provided by this embodiment, the concave surface includes a first concave surface and a second concave surface, and the convex surface includes a first convex surface and a second convex surface; the left side is composed of the first concave surface and the first convex surface; the right side is composed of the second concave surface and the second convex surface; the first concave surface and the second convex surface are arranged opposite to each other on both sides of the top; the first convex surface and the second concave surface are arranged opposite to each other on both sides of the top; the first convex surface and the second concave surface are arranged diagonally, and the first concave surface and the first convex surface are arranged diagonally.

[0045] Preferably, the first concave surface and the second concave surface both have multiple rows of flow holes, and the multiple rows of flow holes are arranged along the first concave surface or the second concave surface. When washing clothes, the washing water can flow along the first concave surface and the second concave surface through the flow holes and flow into the inner cavity of the shell, and then through the flow holes of the drum and flow to the outside of the drum.

[0046] Preferably, the shell as a whole is centrally symmetrical, that is, the first convex surface and the second convex surface have the same structure, and the first concave surface and the second concave surface have the same structure. When washing clothes, the drum rotates forward and reverse, and the lifting rib module has the same lifting effect on the clothes and the same stirring effect on the washing water. Therefore, under the action between the lifting rib module and the clothes, the washing water and the clothes, and the lifting rib module and the washing water, the drum has a higher washing effect.

[0047] <Base>

[0048] like Figure 2b As shown, the base provided in this embodiment is a bent-molded structure as a whole, and a first fixing column is provided on the main surface of the base, which cooperates with the first fixing hole and is used for connecting the shell and the base; a mounting groove is provided in the middle of the main surface, the top of the mounting groove is open, and the bottom and four sides are closed, and a filter can be installed to collect lint generated when washing clothes and lint generated when drying clothes; the main surface is bent downward to form four side walls; when the base is installed on the drum, the bottoms of the four side walls are in contact with the inner wall of the drum, which serves to limit the base.

[0049] Preferably, when the filter is set in the installation groove, the shell acts as a limiter for the filter, and the flow holes on the shell are in the same direction as the mesh holes of the filter, so that the washing water flows stably and vertically to the filter, avoiding weakening the filtering effect of the filter.

[0050] Preferably, buckles extending toward the middle of the base are provided at the bottom of the left and right side walls of the base, which cooperate with the slots on the roller to position the bottom shell and facilitate disassembly; specifically, two buckles are provided at the bottom of the left side wall of the base, and two buckles are provided at the bottom of the right side wall of the base.

[0051] Preferably, a second fixing column is provided in the vertical direction on the side wall of the base for fixing the base; specifically, a second fixing column is provided at the intersection of the left side wall and the front side wall of the base, and a second fixing column is provided at the intersection of the right side wall and the rear side wall of the base.

[0052] Preferably, the base and the drum are detachably connected by a buckle and a second fixing column.

[0053] It should be noted that, in order to adapt to the washing needs of different types of clothes, the base designed in the present invention can be detachably connected to shells of different structures, and thus the lifting rib module of the combination of the base and the shell has different washing functions.

[0054] Washing Machine

[0055] like Figure 3 As shown, the washing machine provided in this embodiment has a drum and a lifting rib module described in any one of the above items is arranged along the depth direction of the drum, and the drum has a second fixing hole and a card slot; the second fixing hole is along the radial direction, and is connected to the second fixing column by a threaded connection, thereby fixing the base to the drum; the card slot is arranged along the depth direction of the drum, and when installing the base, the buckle at the bottom of the base is pushed into the card slot along the depth direction of the drum, thereby positioning the base on the drum.

[0056] Preferably, the drum has a water flow hole. After the washing water enters the interior of the shell through the flow hole, it flows out to the outside of the drum through the water flow hole. The hair or lint in the washing water is intercepted and collected in the filter. At this time, the shell is removed from the base and the hair and lint on the filter are cleaned.

[0057] The housing of the lifting rib module is disassembled and assembled by the following methods:

[0058] Remove the rubber plug, unscrew the screws, and remove the shell from the base. Remove the filter from the mounting slot and clean off the hair and lint collected on the filter.

[0059] Place the filter in the mounting groove of the base, place the shell on the base so that the first fixing hole corresponds to the first fixing column, screw the screw into the first fixing column, and insert the rubber plug into the empty space at the top of the first fixing hole.

[0060] The base of the lifting rib module is disassembled and assembled by the following methods:

[0061] Unscrew the screws and remove the base from the drum; move the buckle out of the slot along the depth of the drum, and the base will be separated from the drum.

[0062] The buckle is locked in the slot along the depth direction of the drum, so that the second fixing hole corresponds to the second fixing column, and the screw is screwed into the second fixing column.

[0063] While the exemplary embodiments of the present disclosure have been specifically illustrated and described above, it should be understood that the present disclosure is not limited to the detailed structures, configurations, or implementations described herein; rather, the present disclosure is intended to encompass various modifications and equivalent configurations within the spirit and scope of the appended claims.
