Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, specifically to a lifting rib structure for the inner drum of a washing machine. Background Technology

[0002] Washing machines are an indispensable appliance in modern homes. The lifting ribs are key components on the inner drum of the washing machine. When the inner drum rotates, the lifting ribs lift the clothes to a certain height and then drop them, achieving washing through tumbling, kneading and other methods.

[0003] Currently, the lifting ribs on the inner drum of washing machines are multiple independent plastic parts, which are installed and fixed to the inner wall of the inner drum of the washing machine one by one by means of clips or screws.

[0004] The above-mentioned method of installing each component individually has the following drawbacks: First, during production and assembly, operators need to align each lifting rib with the mounting position on the inner drum of the washing machine and snap or tighten the screws, which reduces production and assembly efficiency. Second, during daily cleaning and maintenance, users need to disassemble each component individually, clean it, and then reinstall it, which reduces maintenance efficiency.

[0005] Therefore, how to achieve batch assembly and disassembly of lifting ribs in order to improve production assembly efficiency and maintenance efficiency is a technical problem that needs to be solved. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, this invention proposes a lifting rib structure for the inner drum of a washing machine. This invention enables the lifting ribs to be disassembled and assembled in batches, thereby improving both production and assembly efficiency as well as maintenance efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A lifting rib structure for a washing machine inner drum includes multiple lifting ribs disposed on the inner wall of the washing machine inner drum. It also includes an open ring connected to all the lifting ribs. The open ring has a first end and a second end. The first end has a first limiting rod, and the second end has a second limiting rod. Both the first and second limiting rods are parallel to the axial direction of the washing machine inner drum. A first retaining seat and a second retaining seat are disposed on the inner wall of the washing machine inner drum. The first limiting rod abuts against the side of the first retaining seat facing the second retaining seat, and the second limiting rod abuts against the side of the second retaining seat facing the first retaining seat.

[0008] Furthermore, the bottom of the first limiting rod is provided with a tube, which extends in the direction of the second limiting rod. The bottom of the second limiting rod is provided with a rod, which extends in the direction of the first limiting rod. The rod slides in conjunction with the inner cavity of the tube.

[0009] Furthermore, the insert is provided with an elastic element inside, which is used to push the insert rod to slide outward from the insert.

[0010] Furthermore, the opening ring, the first limiting rod, the second limiting rod, the insert, and the insert rod are an integral structure.

[0011] Furthermore, the first limiting rod is provided with two first stop parts, and the first card holder is clamped between the two first stop parts; the second limiting rod is provided with two second stop parts, and the second card holder is clamped between the two second stop parts.

[0012] Furthermore, the lifting rib includes two lifting plates, which are connected on one side near the center of the inner drum of the washing machine, and abut against the inner wall of the inner drum on the other side away from the center of the inner drum. The upper ends of the two lifting plates are connected by a top plate.

[0013] Furthermore, the upper end of the lifting plate is provided with a locking hole, which engages with the open ring, and the top plate is connected to the open ring by fasteners.

[0014] The beneficial effects of this utility model are: 1. By using an open ring to connect all the lifting ribs into a single module, when installing multiple lifting ribs into the washing machine drum, simply insert the entire module into the drum and use the first limiting rod and the first locking seat, and the second limiting rod and the second locking seat to engage, to complete the installation. When removing multiple lifting ribs from the drum, release the engagement of the first limiting rod and the first locking seat, and the second limiting rod and the second locking seat, then remove the entire module from the drum. This allows for batch assembly and disassembly of the lifting ribs, improving both production and maintenance efficiency.

[0015] 2. The insertion and mating structure of the insert rod and insert tube allows the open ring, the first limiting rod, the second limiting rod, the insert tube, and the insert rod to form a closed structure, which enhances the integrity of the open ring and reduces the risk of tearing clothing.

[0016] 3. The added elastic element provides clamping force to the structure, which not only ensures that the first and second limit rods are always in close contact with the first and second card seats, but also absorbs and buffers the vibration energy during operation, further improving the anti-loosening and noise reduction effects.

[0017] 4. The open ring and related components adopt an integrated structure, which reduces the number of parts, reduces assembly errors, and improves structural strength and consistency.

[0018] 5. The two first stop parts and the two second stop parts can axially limit the opening ring and the lifting rib, which helps to further improve the stability and reliability of the lifting rib installed in the inner drum of the washing machine.

[0019] 6. By detachably assembling the lifting rib and the open ring, the lifting rib can be easily replaced and maintained.

[0020] 7. The lifting rib and the open ring are connected by a dual method of snap-fit ​​holes and fasteners, which can improve the firmness and accuracy of the assembly of the lifting rib and the open ring. Attached Figure Description

[0023] To better understand this utility model, it will be further described below with reference to the accompanying drawings. It is worth noting that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings. They are used for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1: A lifting rib structure for a washing machine inner drum, see [reference needed] Figure 5 and Figure 6 It includes multiple lifting ribs 100 and an open ring 200. The multiple lifting ribs 100 are mounted on the open ring 200 to form a pre-assembled integral module. The open ring 200 is preferably made of a resilient engineering plastic and has an opening, see [reference needed]. Figure 1 The open ring 200 has a first end 201 and a second end 202.

[0025] See Figure 1 , Figure 2 and Figure 3 A first limiting rod 203 extending downward (i.e., parallel to the axial direction of the inner drum 300 of the washing machine) is provided at the first end 201. A second limiting rod 204 extending downward is also provided at the second end 202.

[0026] See Figure 7 and Figure 8 On the inner wall of the stainless steel washing machine inner drum 300, a first card holder 301 and a second card holder 302 are cast, welded or stamped.

[0027] The working principle of this embodiment 1 is as follows: When installing the lifting ribs 100 into the inner drum 300 of the washing machine: First, the first end 201 and the second end 202 are pressed together in a direction that brings them closer together. The open ring 200 undergoes elastic deformation, and the first limiting rod 203 and the second limiting rod 204 move closer together. The integral module formed by the multiple lifting ribs 100 and the open ring 200 retracts radially inward. Then, the integral module is inserted into the inner drum 300 of the washing machine, and the first limiting rod 203 and the second limiting rod 204 are moved between the first retaining seat 301 and the second retaining seat 302. Finally, the first end 201 and the second end 202 are released, and the open ring 200 returns to its original position under its own elastic force. The distance between the first limiting rod 203 and the second limiting rod 204 returns to its original position, so that the first limiting rod 203 enters and abuts against the side wall of the first retaining seat 301 facing the second retaining seat 302, and the second limiting rod 204 enters and abuts against the side wall of the second retaining seat 302 facing the first retaining seat 301. See also Figure 9 and Figure 10 When the installation is complete, the lifting rib 100 abuts against the inner wall of the washing machine inner drum 300.

[0028] The limiting rod and the card seat adopt a mutual abutting method (that is, the first limiting rod 203 abuts against the side of the first card seat 301 facing the second card seat 302, and the second limiting rod 204 abuts against the side of the second card seat 302 facing the first card seat 301), forming a mutually locking force-closed structure, which firmly installs the whole module in the inner drum 300 of the washing machine, effectively preventing the open ring 200 from radially loosening or falling off due to vibration during the operation of the washing machine, and ensuring the long-term reliability of the structure.

[0029] When removing the lifting ribs 100 from the inner drum 300 of the washing machine: First, press the first end 201 and the second end 202 in a direction that brings them closer together, so that the first limiting rod 203 moves away from the first retaining seat 301 and the second limiting rod 204 moves away from the second retaining seat 302; then, while keeping the first end 201 and the second end 202 pressed, move the first limiting rod 203 and the second limiting rod 204 out of the space 302 between the first retaining seat 301 and the second retaining seat, and remove the integral module formed by the multiple lifting ribs 100 and the opening ring 200 from the inner drum 300 of the washing machine; the removal operation is then complete.

[0030] As can be seen from the above process, this embodiment 1 has the following advantages: By using an open ring 200 to connect all the lifting ribs 100 into a single module, when installing multiple lifting ribs 100 into the washing machine inner drum 300, simply insert the entire module into the inner drum 300, and install it by engaging the first limiting rod 203 with the first retaining seat 301 and the second limiting rod 204 with the second retaining seat 302. When removing multiple lifting ribs 100 from the inner drum 300, simply release the engagement of the first limiting rod 203 with the first retaining seat 301 and the second limiting rod 204 with the second retaining seat 302, and then remove the entire module from the inner drum 300. This allows for batch assembly and disassembly of the lifting ribs 100, improving both production and maintenance efficiency.

[0031] For example, during production and assembly, multiple lifting ribs 100 can be installed into the washing machine inner drum 300 together, eliminating the need to install each lifting rib 100 individually, thus improving production and assembly efficiency. Similarly, during routine cleaning and maintenance, multiple lifting ribs 100 can be removed from the washing machine inner drum 300 together, or multiple lifting components 100 can be installed into the washing machine inner drum 300 together, eliminating the need for individual removal and installation, thus improving maintenance efficiency.

[0032] Example 2: Based on Embodiment 1, improvements were made to the first limiting rod 203 and the second limiting rod 204.

[0033] As attached Figure 3 As shown, a plug 205 is fixedly installed at the bottom of the first limiting rod 203, and the opening of the plug 205 extends toward the direction of the second limiting rod 204. A plug 206 is fixedly installed at the bottom of the second limiting rod 204, and the plug 206 extends toward the direction of the first limiting rod 203. The plug 206 is inserted into the inner cavity of the plug 205.

[0034] As the first end 201 and the second end 202 are pressed together in a direction that brings them closer together, the insertion rod 206 slides deeper into the insertion cylinder 205.

[0035] When the first end 201 and the second end 202 are released, the two ends of the opening ring 200 open under the action of their own elastic force, which increases the distance between the first limiting rod 203 and the second limiting rod 204 at both ends of the opening ring 200, causing the insertion rod 206 to slide to the outside of the insertion cylinder 205.

[0036] The insertion and engagement structure of the aforementioned insertion rod 206 and insertion cylinder 205 allows the opening ring 200, the first limiting rod 203, the second limiting rod 204, the insertion cylinder 205, and the insertion rod 206 to form a closed structure, which enhances the integrity of the opening ring 200 and reduces the risk of tearing clothing.

[0037] Example 3: Based on Example 2, as shown in the appendix Figure 3 As shown, an elastic element 207 is also provided inside the insert 205, which is preferably a helical compression spring. One end of the spring abuts against the bottom of the inner cavity of the insert 205, and the other end abuts against the end of the inserted rod 206.

[0038] When the first end 201 and the second end 202 are pressed together in a direction that brings them closer to each other, the insertion rod 206 slides deeper into the insertion cylinder 205, and the elastic element 207 is compressed.

[0039] When the first end 201 and the second end 202 are released, the two ends of the opening ring 200 open under their own elastic force, causing the insertion rod 206 to slide outward toward the insertion cylinder 205. Furthermore, the restoring force of the elastic element 207 continuously pushes the insertion rod 206, also causing it to slide outward toward the insertion cylinder 205. Thus, indirectly, the first limiting rod 203 and the second limiting rod 204 always have a tendency to open outward and press against the first and second retaining seats 301 and 302. This not only eliminates the mating clearance and provides preload, but also effectively buffers vibration, achieving noise reduction and anti-loosening effects.

[0040] Example 4: This embodiment 4 is a preferred manufacturing solution of the above embodiments. The open ring 200, the first limiting rod 203, the second limiting rod 204, the insert 205, and the insert rod 206 are formed into a single structure by a one-time injection molding process. The one-piece molding structure reduces the cumulative error and connection strength problems caused by assembling multiple parts, and has the advantages of robust structure, high reliability, and low production cost.

[0041] Further details are attached. Figure 3 As shown, the first limiting rod 203 is provided with two first stop portions 209, and the first stop portions 209 and the first limiting rod 203 are also an integral structure. The second limiting rod 204 is provided with two second stop portions 210, and the second stop portions 210 and the second limiting rod 204 are also an integral structure.

[0042] See Figure 9 and Figure 10 When the first limiting rod 203 enters the first retaining seat 301, the first retaining seat 301 is located between the two first stop portions 209; when the second limiting rod 204 enters the second retaining seat 302, the second retaining seat 302 is located between the two second stop portions 210. The two first stop portions 209 and the two second stop portions 210 can axially limit the opening ring 200 and the lifting rib 100, which is beneficial to further improve the stability and reliability of the lifting rib 100 installed in the inner drum 300 of the washing machine.

[0043] Example 5: This embodiment 5 defines the specific structure of the lifting rib 100.

[0044] As attached Figure 4 Appendix Figure 5 and attached Figure 6 As shown, each lifting rib 100 includes two lifting plates 101. The two lifting plates 101 are connected to each other on the side near the center of the washing machine inner drum 300, forming a V-shaped or U-shaped cross-section; while on the side away from the center of the washing machine inner drum 300 (i.e., the side near the inner drum wall of the washing machine inner drum 300), the ends of the two lifting plates 101 abut against the inner wall of the washing machine inner drum 300. At the upper end of the two lifting plates 101, a top plate 102 is connected, so that the top of the lifting rib 100 forms a closed structure, which enhances its own rigidity.

[0045] As attached Figure 4 Appendix Figure 5 and attached Figure 6 As shown, to achieve a detachable connection between the lifting rib 100 and the open ring 200, a locking hole 1011 is provided at the upper end of the lifting plate 101. During installation, the open ring 200 can be inserted into the locking hole 1011 for initial positioning. Furthermore, in this embodiment 5, the top plate 102 is also connected to the open ring 200 via a fastener 400, thereby achieving reliable fixation. During disassembly, the fastener 400 is removed, and the open ring 200 is pulled out of the locking hole 1011, thus separating the open ring 200 and the lifting rib 100, facilitating replacement if the lifting rib 100 is damaged.

[0046] Example 6: This embodiment 6 is a specific embodiment of the fastener 400 in embodiment 5.

[0047] See Figure 1 A positioning screw hole 208 is provided on the open ring 200 at a position corresponding to the top plate 102.

[0048] See Figure 4 A through hole 1021 is provided on the top plate 102.

[0049] See Figure 5 and Figure 6 Fastener 400 uses positioning bolts. During assembly, the positioning bolts are screwed into the through hole 1021 of the top plate 102 and the positioning screw hole 208 of the open ring 200 from top to bottom, thereby firmly locking the lifting rib 100 onto the open ring 200. During disassembly, the positioning bolts are screwed upwards out of the positioning screw hole 208 and the through hole 1021, and then the open ring 200 is pulled out of the retaining hole 1011, thus separating the open ring 200 and the lifting rib 100.

[0050] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
