Description

Technical Field

[0001] This application relates to the field of garment processing technology, and in particular to a lifting rib and garment processing equipment. Background Technology

[0002] In related technologies, clothing handling equipment such as washing machines or dryers are equipped with lifting ribs in the drum. The lifting ribs are used to lift the clothes in the drum during the drum's rotation so that the clothes fall off later, thereby tumbling and tumbling the clothes.

[0003] To enhance the structural strength and durability of the lifting ribs, related technologies typically employ a multi-layered design. However, this multi-layered structure presents manufacturing challenges, as achieving a complete seal between layers is often difficult. This allows water to easily seep into the cavities between layers during garment processing. Lacking a dedicated drainage path, the seeped water accumulates over time, easily breeding bacteria and producing odors, thus negatively impacting the internal hygiene of the garment processing equipment. Utility Model Content

[0004] This application provides a lifting rib that can effectively drain water that has seeped into it, thus avoiding hygiene problems caused by water accumulation.

The first water passage hole connects at least a portion of the space between the mounting bracket and the outer casing, and water in the space flows out through the first water passage hole in a direction away from the outer casing.

[0006] In some embodiments, the lifting rib protrudes from the cylinder wall of the roller, and the extension direction of the first water passage is at least partially opposite to the protrusion direction of the lifting rib.

[0007] In some embodiments, the housing does not have an opening or through hole penetrating the housing.

[0008] In some embodiments, the mounting bracket has a first opening and a water passage cavity communicating with the first water passage hole; and A sandwich space is formed between the outer shell and the mounting bracket, and water in the sandwich space can flow into the water passage cavity through the first water passage hole.

[0009] In some embodiments, the area of ​​the drum wall covered by the lifting ribs has drainage holes penetrating the drum wall. The water passage cavity is connected to the drain hole.

[0010] In some embodiments, the mounting bracket is provided with a connector that is fixedly connected to the wall of the roller, and the lifting rib further includes: The base is detachably connected to the first opening, and the base is provided with a clearance opening to avoid the connector.

[0011] In some of these embodiments, it also includes: The base has a drainage cavity, and the cavity wall of the drainage cavity has a second water passage hole that communicates with the water passage cavity.

[0012] In some embodiments, the base includes: The base plate has the second water passage hole; A surrounding panel is provided around the periphery of the base plate and is located on the side of the base plate away from the mounting bracket, so as to define the drainage cavity together with the base plate. The surrounding panel has a communication opening that connects the drainage cavity and the clothing processing cavity.

[0013] In some embodiments, the mounting bracket includes a connecting column, the base plate has threaded holes, and the lifting rib further includes: The first threaded component passes through the connecting post and is threaded into the threaded hole.

[0014] In some embodiments, the base plate further has connecting holes spaced apart from the threaded holes, and the lifting ribs further include: The second threaded component is inserted through the connecting hole and threaded to the cylinder wall.

[0015] In some embodiments, the surface of the enclosure facing the mounting bracket has a stepped structure, and the edge of the mounting bracket enclosing the first opening abuts against the stepped surface of the stepped structure.

[0016] In some embodiments, the mounting bracket includes: Two first sidewalls are arranged opposite each other along the circumference of the roller; Two second sidewalls are arranged opposite each other along the axial direction of the roller, one second sidewall being connected to one end of the two first sidewalls along the axial direction, and the other second sidewall being connected to the other end of the two first sidewalls along the axial direction; and The top wall is connected to the top of the two first side walls and the two second side walls away from the first opening, and together with the two first side walls and the two second side walls, defines the water passage cavity; The outer casing is disposed on the side of the two first sidewalls, the two second sidewalls, and the top wall opposite to the first opening, and the first water passage is disposed on at least one of the first sidewalls, the second sidewalls, and the top wall.

[0017] In some embodiments, the distance between the two first sidewalls along the circumference of the roller decreases in a direction opposite to the first opening; and / or, Along the direction away from the first opening, the distance between the two second sidewalls along the axial direction of the roller is set to decrease.

[0020] During garment processing, wash water inevitably seeps into the internal cavities of the lifting ribs through tiny gaps.

These bacteria and odors not only contaminate subsequently washed clean garments, causing secondary pollution.

[0021] This embodiment of the application provides a dedicated drainage channel for water that seeps into the space between the outer casing and the mounting bracket by setting a first water passage hole on the mounting bracket connected to the outer casing. Water can be discharged promptly and smoothly through the first water passage hole as the roller rotates or under gravity, avoiding long-term accumulation, thereby effectively solving the problem of bacteria growth and odor generation due to water accumulation affecting the hygiene of the garment processing equipment.

[0022] At the same time, timely drainage also avoids corrosion, aging or performance degradation that may occur when internal structural components are immersed in water for a long time, thereby extending the service life of the lifting ribs and even the entire roller assembly and improving the long-term reliability of the product.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] This application provides a garment processing device, which refers to equipment used for processing garments. Common garment processing equipment includes washing machines, dryers, and washer-dryer combos. Its main function is to automatically and efficiently complete the processes of washing, rinsing, and dehydrating garments.

[0028] In this embodiment, we use a washing machine as an example for describing the clothing handling device, especially a front-loading washing machine. For clothes handling devices that are dryers or washer-dryer combos, please refer to the relevant settings.

[0029] The garment processing equipment includes a cabinet and a drum assembly housed within the cabinet. The cabinet serves as the outer frame of the garment processing equipment, providing a relatively sealed cavity to house the drum assembly, which is one of the core components for realizing the functions of washing and drying clothes. The cabinet provides a protective shell for the drum assembly and supports it, ensuring its stability during operation.

[0030] like Figure 1 As shown, the drum assembly includes an outer drum and a roller 20 rotatably disposed within the outer drum. The outer drum provides rotational support for the roller 20 (e.g., by connecting the roller 20's shaft via a bearing), and does not directly contact the clothing, nor participate in the tumbling or shaking of the clothing. The roller 20 has a clothing processing chamber 20a, which provides a dedicated area for placing and processing clothing.

[0031] Since the rotation of the drum 20 alone is insufficient to tumble the clothes, if the inner wall of the drum 20 is smooth, the clothes will easily rotate synchronously with the drum 20, and cannot form an effective tumbling and tumbling action, resulting in insufficient treatment of some parts of the clothes (such as stains remaining during washing, uneven heating during drying).

[0032] like Figure 1 and Figure 2As shown in this embodiment, the garment processing equipment also includes lifting ribs 10. The lifting ribs 10 are disposed within the garment processing chamber 20a and detachably connected to the drum wall of the drum 20. When the drum 20 rotates, the lifting ribs 10 move along with the inner wall of the drum 20. Their protruding structures can hook or lift the garments, forcibly lifting them upwards. When the garments are lifted to a certain height, they will detach from the lifting ribs 10 due to gravity and fall freely, colliding and rubbing against the inner wall of the drum 20 or other garments. Through this cycle of lifting and falling, the garments can be fully tumbled and shaken within the drum 20, ensuring that stains are evenly removed during washing and that heating is more comprehensive during drying, ultimately improving the working efficiency and processing effect of the garment processing equipment.

[0033] The lifting rib 10 has an overall elongated structure and extends along its length. The length direction of the lifting rib 10 is approximately in the same direction as the axial direction of the drum 20. That is, the lifting rib 10 is installed on the inner side of the drum 20 along the central axis of the drum 20. The two ends of the lifting rib 10 are respectively facing the two axial sides of the drum 20, and the whole is parallel to the axial direction of the drum 20.

[0034] During garment processing, wash water inevitably seeps into the internal cavities of the lifting ribs through tiny gaps. In related technologies, this water has poor flow and, if left untreated, easily becomes a breeding ground for bacteria and mold in warm, humid environments, leading to unpleasant odors. These bacteria and odors not only contaminate subsequently washed clean garments, causing secondary pollution.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, to solve the above problems, the lifting rib 10 includes a mounting bracket 11 and a housing 12. The housing 12 covers the mounting bracket 11. By providing a first water passage hole on the mounting bracket 11 connected to the housing 12, the first water passage hole connects at least part of the space between the mounting bracket 11 and the housing 12, thus providing a dedicated drainage channel for water that seeps into the space between the housing 12 and the mounting bracket 11. The water in the space flows out through the first water passage hole in a direction away from the housing 12.

[0036] Water can be drained smoothly and promptly through the first drainage hole as the roller 20 rotates or by gravity, preventing long-term accumulation and effectively solving the problem of bacteria growth and odors caused by water accumulation, which affects the hygiene of the garment processing equipment. At the same time, timely drainage also prevents corrosion, aging, or performance degradation that may occur when internal structural components are immersed in water for extended periods, thereby extending the service life of the lifting rib 10 and even the entire roller 20 assembly, and improving the long-term reliability of the product.

[0037] In some embodiments, the lifting rib 10 protrudes from the cylinder wall of the roller 20, and the protrusion direction is generally pointing towards the center of the roller 20. The extension direction of the first water passage is at least partially opposite to the protrusion direction of the lifting rib 10. That is, the axial direction of the first water passage is towards the cylinder wall of the roller 20. The extension direction of the first water passage can guide the flow direction of water in the space between the housing 12 and the mounting bracket 11.

[0038] As the drum 20 rotates, the water inside the lifting ribs 10 naturally flows to the lowest point under the influence of gravity. The first water passage hole faces the opening direction of the drum 20 wall, providing the water flow with the most direct and gravity-compliant outlet. The water does not need to turn or flow backwards; it can be thrown out or flow out along the shortest path, thus improving the efficiency and thoroughness of drainage.

[0039] In some embodiments, at least a portion of the inner side of the first water passage 11a is provided with a pipe structure extending toward the water passage cavity 11c (e.g., Figure 7 The extension direction of the pipe structure is opposite to the protrusion direction of the lifting rib 10, and the first water passage hole 11a penetrates the corresponding pipe structure. The pipe structure and the mounting bracket 11 are integrally formed or fixedly connected to form a flow channel similar to a "short pipe", thus avoiding the first water passage hole 11a being set only on the thin-walled structure.

[0040] This design not only significantly enhances the structural strength and rigidity of the first water passage 11a, enabling it to withstand the water flow impact and mechanical stress generated when the drum rotates at high speed, preventing deformation or damage to the first water passage 11a due to long-term use, but also the extended design of the pipe structure forms an effective flow guiding path, ensuring that the water accumulated in the interlayer space 10a can flow smoothly and quickly into the water passage cavity 11c, reducing water flow resistance and improving drainage efficiency.

[0041] Furthermore, in related technologies, the lifting rib 10 is usually made of plastic injection molding. When the garment processing equipment is working, the lifting rib 10 needs to be in contact with washing water containing detergent (mostly weakly alkaline or weakly acidic) for a long time. Some also need to withstand high-temperature washing programs (such as sterilization washing above 60°C). Under the long-term effects of acid, alkali and high temperature, the plastic lifting rib 10 is prone to aging, embrittlement, and even surface cracking and swelling, which leads to a decrease in the structural stability of the lifting rib 10. On the other hand, during repeated contact with clothing, the lifting rib 10 needs to be frequently subjected to friction and snagging of clothing (such as metal zippers and buttons on clothing coming into contact with the surface of the lifting rib 10). The surface hardness and wear resistance of plastic are relatively weak, and after long-term use, the surface is prone to scratches and wear.

[0042] In this embodiment, the mounting bracket 11 is a plastic part with an overall arched structure. Its shape is similar to an arc-shaped arch that protrudes towards the central axis of the roller 20. The top of the arch faces the central axis of the roller 20 (i.e., the side away from the cylinder wall of the roller 20), and the two sides of the arc extend towards the cylinder wall of the roller 20 and are fixedly connected to the cylinder wall. That is, the mounting bracket 11 is at least partially used for fixed connection with the cylinder wall of the roller 20. It can be fixedly connected by screws, buckles, etc., to provide a stable installation foundation for the entire lifting rib 10 and ensure that the lifting rib 10 does not shift when it rotates synchronously with the roller 20.

[0043] like Figure 2 , Figure 3 and Figure 4 As shown, the mounting bracket 11 has a first opening 11b and a water passage cavity 11c. The first opening 11b is located on the side of the water passage cavity 11c away from the central axis of the roller 20. That is, the bottom of the arched mounting bracket 11 forms a through first opening 11b, which is connected to the clothing processing cavity 20a. The cavity shape of the water passage cavity 11c is consistent with the outer contour of the arched body and is an arc-shaped protrusion.

[0044] The outer shell 12 adopts an arc-shaped cover structure that matches the shape of the mounting bracket 11. It is made of corrosion-resistant metal material (such as stainless steel). The outer shell 12 covers the side of the mounting bracket 11 away from the first opening 11b, that is, the side facing the central axis of the drum 20, forming a certain degree of protection for the mounting bracket 11. The outer shell 12 also has a certain degree of corrosion resistance, which can effectively resist the corrosive effect of washing liquid and water vapor inside the drum 20 on the lifting ribs 10. At the same time, the metal material has better structural strength and surface wear resistance, preventing the outer shell 12 from being scratched or worn due to long-term use, thus extending the service life of the outer shell 12.

[0045] Furthermore, the aforementioned interlayer space 10a is formed between the outer shell 12 and the mounting bracket 11. Since the outer shell 12 and the mounting bracket 11 are independently manufactured components, a small gap needs to be reserved during assembly to accommodate the installation. As a result, the contact surfaces of the outer shell and the mounting bracket 11 cannot achieve a 100% fit. At the same time, the lifting rib 10 needs to rotate synchronously with the drum 20. The vibration generated by long-term rotation will cause the assembly gap between the outer shell 12 and the mounting bracket 11 to gradually widen. The originally small gap will become a channel for water to seep in. Especially during washing, the water is squeezed towards the drum wall by centrifugal force, making it easier to seep into the interlayer space 10a through these gaps.

[0046] The interlayer space 10a can temporarily store water that splashes or seeps into the gap between the roller 20 and the roller. In this embodiment, the wall of the water passage cavity 11c has a first water passage hole 11a that communicates with the water passage cavity 11c. Understandably, the first water passage hole 11a is provided on the mounting bracket 11 and communicates with the interlayer space 10a. Water in the interlayer space 10a can flow into the water passage cavity 11c through the first water passage hole 11a, and then enter the clothing processing cavity 20a through the first opening 11b or be discharged directly with the drainage system of the roller 20, effectively preventing water from accumulating in the interlayer space 10a for a long time.

[0047] like Figure 2 , Figure 3 and Figure 4 As shown, multiple first water passage holes 11a are provided, and the multiple first water passage holes 11a are arranged at intervals on the cavity wall surface of different water passage cavities 11c along the arched outline of the mounting bracket 11. Since the water in the interlayer space 10a may be in a dynamic distribution state due to the rotation of the lifting rib 10 with the roller 20 (such as when the roller 20 rotates to different angles, the water will converge to different areas of the interlayer space 10a under the action of gravity), the multiple first water passage holes 11a can cover more areas of the interlayer space 10a, so that no matter where the water converges, it can quickly flow into the water passage cavity 11c through the nearest first water passage hole 11a, avoiding the problem of untimely drainage caused by the water being far away from the opening position due to a single opening.

[0048] Water in the interlayer space 10a can be smoothly guided into the water passage cavity 11c and discharged through the first water passage hole 11a, which can promptly empty the water in the interlayer space 10a. On the one hand, this can prevent the water from accumulating and breeding bacteria and mold, and at the same time prevent the water from absorbing the fibers shed from the clothes and detergent residue left over from washing, thereby keeping the interior of the interlayer space 10a clean, eliminating odors, and preventing dirty water from contaminating the clothes during subsequent use. On the other hand, it can prevent the outer shell 12 from being in contact with water for a long time, especially in washing environments where the water flow contains detergent and is weakly alkaline or weakly acidic. This can effectively slow down or even prevent the outer shell 12 from being corroded, thereby preventing the outer shell 12 from rusting. This not only ensures the structural stability of the lifting rib 10 and extends its service life, but also prevents rust residue from falling off and adhering to the clothes, avoiding damage or secondary pollution to the clothes.

[0049] The outer shell 12 can also prevent water in the clothes processing chamber 20a from entering the interlayer space 10a through the outer shell 12, reducing the water flow in the clothes processing chamber 20a (such as splashing water during washing, water spun out during spin-drying, and water squeezed out by the clothes) from seeping into the interlayer space 10a through the outer shell 12 itself, reducing the water pressure in the interlayer space 10a, and allowing the subsequent drainage design through the first water passage hole 11a and water passage chamber 11c to more efficiently drain the accumulated water, avoiding the problem of untimely drainage caused by a large amount of water rushing in.

[0050] It should be noted that in this embodiment, the outer shell 12 does not have any openings or through holes. Providing openings or through holes would disrupt the material continuity of the outer shell 12, leading to stress concentration around the openings or through holes. The design without through openings maintains the overall structural integrity of the outer shell 12, ensuring that stress is evenly distributed on the surface of the outer shell 12. This reduces the risk of cracking or deformation of the outer shell 12 due to stress concentration, and ensures that it maintains a stable shape even when subjected to the long-term impact of the rotating roller 20.

[0051] In some embodiments, the area of ​​the cylinder wall of the roller 20 covered by the lifting rib 10 has a plurality of drainage holes penetrating the cylinder wall. That is, in the radial direction of the roller 20 passing through the center line of the lifting rib 10 itself, a plurality of drainage holes are located within the projection of the lifting rib 10. The drainage holes can be used to drain the squeezed water from the clothes during the dehydration process of the clothes processing equipment.

[0052] During the washing process, the drain holes covered by the lifting ribs 10 will not directly contact the clothes, reducing the risk of the clothes being caught or damaged by the drain holes during the washing process and improving the washing quality.

[0053] The water in the interlayer space 10a can be discharged to the outside of the clothes processing chamber 20a through the first water passage hole 11a, the water passage cavity 11c, the first opening 11b and the drain hole in sequence. That is, the water in the interlayer space 10a can directly enter the drain hole of the drum wall through the first opening 11b, reducing contact with the clothes in the clothes processing chamber 20a and reducing the possibility of water in the interlayer space 10a contaminating the clothes. It can be applied to high-temperature sterilization washing, delicate fabric washing and other scenarios with high requirements for cleanliness and clothing protection.

[0054] Because there is a certain assembly gap between the mounting bracket 11, the outer shell 12 and the drum wall of the roller 20, a small amount of residual water in the gap can be discharged directly through the drain hole, avoiding long-term contact between water and the fixed structure, such as metal fasteners (such as screws connecting the lifting rib 10 and the drum wall), which can significantly reduce the risk of corrosion and extend the overall service life of the lifting rib 10 and the drum wall of the roller 20.

[0055] like Figure 4 and Figure 6As shown, in some embodiments, the drum 20 is provided with a plurality of drainage holes, some of which are located in areas not covered by the lifting ribs 10, and others are located in areas covered by the lifting ribs 10. A water passage gap 11d is provided between the mounting bracket 11 and the drum wall. The water passage gap 11d connects the first opening 11b and the garment processing chamber 20a. That is, water in the interlayer space 10a can sequentially pass through the first water passage hole 11a, the water passage chamber 11c, the first opening 11b, the water passage gap 11d, the garment processing chamber 20a, and the drainage holes to be discharged outside the garment processing chamber 20a, and then discharged along with other water in the chamber (such as washing wastewater and spin-drying water) through the drainage holes in the uncovered area.

[0056] If water can only be discharged from the drainage holes covered by the lifting rib 10, when the instantaneous water volume is huge, the limited number of these drainage holes may lead to poor drainage, causing water to accumulate near the lifting rib 10, affecting drainage efficiency, and even generating additional noise and vibration.

[0057] In areas not covered by the lifting ribs 10, more drainage holes can be installed, effectively avoiding drainage blockage, increasing the drainage volume per unit time, and thus improving drainage efficiency.

[0058] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the lifting rib 10 also includes a base 13, which is a plastic part with a rounded outer edge. The base 13 is detachably connected to the first opening 11b, and its size and shape are adapted to the size and shape of the first opening 11b. The thickness of the base 13 along the radial direction of the roller 20 is less than the thickness of the mounting bracket 11 along the radial direction of the roller 20, so that the mounting bracket 11 can cover the base 13. The mounting bracket 11 and the base 13 can form a water passage cavity 11c.

[0059] The base 13 is fixedly connected to the cylinder wall of the roller 20. Since the base 13 and the mounting bracket 11 are detachably connected, when the first water passage hole 11a inside the lifting rib 10 is blocked or damaged, it is not necessary to remove the entire lifting rib 10. Instead, the outer shell 12 and the mounting bracket 11 can be partially removed to clean the first water passage hole 11a.

[0060] To achieve the pre-positioning of the mounting bracket 11 on the base 13, a snap-fit ​​structure 14 is provided on the side of the mounting bracket 11 facing the base 13, and the base 13 has a slot 13c that can be engaged by the snap-fit ​​structure 14. Specifically, multiple snap-fit ​​structures 14 are provided and arranged at intervals along the length of the mounting bracket 11 to ensure a uniform and stable connection between the mounting bracket 11 and the base 13. This snap-fit ​​design not only enables rapid positioning during assembly and improves assembly efficiency, but also provides additional fixing force after the mounting bracket 11 and the base 13 are connected, enhancing the reliability of the connection between the two.

[0061] In practical applications, the snap-fit ​​structure 14 can take the form of elastic claws, which facilitates easy insertion into the slot 13c of the base 13 during assembly. After the snap-fit ​​structure 14 is fully inserted into the slot 13c, the elastic claws return to their original shape and form a reliable snap-fit ​​engagement with the slot 13c.

[0062] Furthermore, the spaced arrangement of multiple snap-fit ​​structures 14 ensures more even stress distribution between the mounting bracket 11 and the base 13, preventing deformation or damage caused by localized stress concentration and extending the service life of the lifting rib 10. This snap-fit ​​connection method also facilitates subsequent disassembly and maintenance. When cleaning or replacing internal components is required, simply apply appropriate external force to disengage the snap-fit ​​structure 14 from the latch 13c, easily separating the mounting bracket 11 from the base 13, greatly improving maintenance convenience.

[0063] To enhance the strength of the mounting bracket, a reinforcing rib 15 is provided on the side of the mounting bracket 11 facing the base 13. Multiple reinforcing ribs 15 are provided, extending along the width direction of the mounting bracket 11, and are arranged at intervals. The design of these reinforcing ribs 15 not only significantly enhances the overall structural strength and rigidity of the mounting bracket 11, but also effectively improves its resistance to deformation and load-bearing capacity.

[0064] The reinforcing ribs 15 extend along the width of the mounting bracket 11, enabling them to effectively resist the centrifugal force generated during the rotation of the drum and the bending stress caused by the impact of clothing, thus preventing the mounting bracket 11 from warping or deforming during long-term use.

[0065] In some embodiments, the mounting bracket 11 is provided with a connector that is fixedly connected to the cylinder wall. The connector can be a fixing screw or a snap-fit ​​post. The base 13 is provided with a clearance opening to avoid the connector, that is, the connector can directly pass through the mounting bracket 11 through the clearance opening and directly connect to the cylinder wall of the roller 20, so that the assembly of the base 13 does not affect the stability of the mounting bracket 11. There is no need to indirectly transmit the fixing force through the base 13, avoiding connection failure caused by deformation or aging of the base 13, and ensuring the connection strength between the mounting bracket 11 and the cylinder wall of the roller 20.

[0066] Furthermore, since the mounting bracket 11 can be directly connected to the cylinder wall of the roller 20, the same mounting bracket 11 can be switched between configurations without or with the base 13 without structural modification. This reduces mold development costs, eliminates the need to design different mounting brackets 11 for the two scenarios, and provides flexibility for production and after-sales service, allowing for the selection of whether or not to add the base 13 according to requirements.

[0067] like Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the base 13 has a drain cavity 13b, which is located on the side of the base 13 away from the water passage cavity 11c. The wall of the drain cavity 13b has a second water passage hole 13a that communicates with the water passage cavity 11c. The drain cavity 13b can form a transition buffer space between the water passage cavity 11c and the inner wall of the roller 20. When the roller 20 rotates at high speed (such as in a dehydration process), the water flow discharged from the water passage cavity 11c is fast and has a large impact force. The drain cavity 13b can appropriately weaken the impact of the water flow from the water passage cavity 11c on the wall of the roller 20.

[0068] The water in the interlayer space 10a can enter the drainage chamber 13b through the first water passage hole 11a, the water passage cavity 11c, the first opening 11b and the second water passage hole 13a in sequence, which allows the water flow to be guided with a shorter path and less resistance, thus accelerating the drainage of the interlayer space 10a.

[0069] To enhance the structural strength and stability of the base 13, the walls of the drainage cavity 13b are provided with crisscrossing reinforcing ribs 16. These reinforcing ribs 16 adopt a grid-like layout design, including longitudinal reinforcing ribs extending along the length of the base 13 and transverse reinforcing ribs extending along the width, which intersect to form a stable grid support structure. This layout of reinforcing ribs 16 not only significantly improves the overall rigidity of the base 13, enabling it to withstand the water pressure impact and mechanical stress generated by the high-speed rotation of the drum, but also effectively prevents the base 13 from deforming or warping during long-term use.

[0070] like Figure 5 , Figure 6 and Figure 8 As shown, further, multiple second water passage holes 13a can be provided, and multiple second water passage holes 13a can be arranged at intervals on the base 13. When the roller 20 rotates at high speed, the water flow discharged from the water passage cavity 11c through the first opening 11b is fast and has a large flow rate. A single second water passage hole 13a is prone to drainage delay due to water flow congestion. Multiple second water passage holes 13a can divide the water flow into multiple small flow streams, which enter the drainage cavity 13b at the same time, greatly reducing the water flow pressure of a single second water passage hole 13a.

[0071] Understandably, if the drain hole is configured to be located only in the area of ​​the roller 20 covered by the lifting rib 10, the water in the interlayer space 10a can be discharged to the outside of the garment processing chamber 20a through the first water passage hole 11a, the water passage cavity 11c, the first opening 11b, the second water passage hole 13a, the drain cavity 13b, and the drain hole in sequence. This shortens the drainage path and reduces the problem of water accumulating in the garment processing chamber 20a and adhering to the garment fibers or remaining in the dead corners of the roller 20 wall. Furthermore, the covering of the drain hole by the lifting rib 10 can also protect the drain hole from direct impact from the garment (such as the garment hitting the edge of the drain hole when rotating at high speed), reducing the risk of deformation and damage to the drain hole.

[0072] like Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the base 13 includes a base plate 131 and a surrounding plate 132. The base plate 131 and the surrounding plate 132 can be integrally injection molded to reduce potential leakage points. The base plate 131 is the main structure of the base 13 and is provided with the aforementioned second water passage hole 13a. The surrounding plate 132 is the side wall structure of the base 13. The surrounding plate 132 surrounds the periphery of the base plate 131 and can be in a vertical or slightly inclined state. The surrounding plate 132 is located on the side of the base plate 131 away from the mounting bracket 11 and together with the base plate 131 defines the drainage cavity 13b.

[0073] The enclosure 132 has a connecting port 132a that connects the drain chamber 13b and the clothes handling chamber 20a. Multiple connecting ports 132a can be provided along the circumference of the enclosure 132. Understandably, in one configuration, if the drain hole is only provided in the area of ​​the drum 20 covered by the lifting rib 10, the water in the clothes handling chamber 20a can be discharged sequentially through the connecting port 132a, the drain chamber 13b and the drain hole. That is, the clothes handling chamber 20a will generate a large amount of high-speed spin-out water during the dehydration process, or the overall wastewater needs to be discharged after washing. It can quickly flow into the drain chamber 13b through the connecting port 132a of the enclosure 132 and then be discharged through the drain hole.

[0074] In another configuration, if the area of ​​the roller 20 not covered by the lifting rib 10 is also provided with drainage holes, the water in the interlayer space 10a flows to the drainage chamber 13b and has multiple paths. That is, in addition to flowing out directly through the drainage port covered by the lifting rib 10, it can also be discharged through the connecting port 132a and then through the drainage hole not covered by the lifting rib 10. Since the drainage hole is located in an open area, workers do not need to spend extra time to ensure the precise alignment of the lifting rib 10 with the drainage hole on the cylinder wall during production line or after-sales maintenance. They only need to fix the lifting rib 10 in the predetermined position, which improves the efficiency of production assembly and maintenance replacement.

[0075] like Figure 7 and Figure 8As shown, in some embodiments, the mounting bracket 11 includes a connecting post 114, which may be an integrally formed protrusion extending toward the base plate 131 on the mounting bracket 11. The base plate 131 is a hollow cylinder with a threaded hole 131a. The lifting rib 10 also includes a first threaded connector, which passes through the connecting post 114 and is threaded into the threaded hole 131a. That is, the central axis of the connecting post 114 is aligned with a predetermined threading direction, which guides the mounting bracket 11 to quickly find the correct assembly position with the base 13, preventing the mounting bracket 11 from shifting.

[0076] The threaded connection, through its self-locking characteristic, ensures that the mounting bracket 11 and the plastic self-connection do not loosen due to the vibration and centrifugal force of the rotating roller 20, which is the key to achieving a stable connection.

[0077] Furthermore, the base plate 131 also has connecting holes 131b spaced apart from the threaded holes 131a. The lifting rib 10 also includes a second threaded connector, which passes through the connecting hole 131b and is threaded to the cylinder wall of the roller 20. If the interior of the lifting rib 10 needs maintenance, the first threaded connector connecting the mounting bracket 11 and the base plate 131 can be unscrewed to partially disassemble the lifting rib 10 for cleaning or maintenance. Throughout the process, the base 13 remains firmly fixed to the roller 20 by the second threaded connector, without the need for repositioning and alignment.

[0078] If the entire lifting rib 10 needs to be replaced, the maintenance personnel only need to unscrew the second screw that fixes the base 13 to the cylinder wall to remove the entire lifting rib 10 and replace it with a new lifting rib 10, which is convenient to operate.

[0079] In other embodiments, the mounting bracket 11 can also be equipped with an independent connector that connects directly to the wall of the roller 20. The base 13 and its second screw connector serve as auxiliary positioning and support. In this dual-fixation mode, the mounting bracket 11 achieves primary positioning through its own connector, ensuring its core function and driving the stability of clothing tumbling. The base 13 provides auxiliary support through the second screw connector, sharing some of the vibration and load, making the entire structure more stable.

[0080] like Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments, the surface of the enclosure 132 facing the mounting bracket 11 has a stepped structure 1321. The stepped structure 1321 surrounds the enclosure 132 in the circumferential direction. The edge of the mounting bracket 11 that encloses the first opening 11b abuts against the stepped surface of the stepped structure 1321. During assembly, the edge of the first opening 11b of the mounting bracket 11 only needs to abut against the stepped surface to quickly determine the relative position with the base 13, without the need for repeated adjustments to the alignment, thus reducing the assembly difficulty.

[0081] The height difference formed by the stepped surface can also prevent the mounting bracket 11 from shifting. When the roller 20 rotates at high speed, the lifting rib 10 will be subjected to huge centrifugal force. This force will try to separate the mounting bracket 11 and the base 13. The stepped structure 1321 itself can also provide a certain anti-pull-out capability to prevent the two parts from separating under vibration.

[0082] This ensures that the first opening 11b of the mounting bracket 11 is aligned with the second water passage hole 13a and the drainage cavity 13b of the base, preventing water blockage or side leakage due to misalignment and ensuring smooth drainage path within the interlayer space 10a.

[0083] like Figure 6 As shown, in some embodiments, the mounting bracket 11 includes two first sidewalls 111, two second sidewalls 112, and a top wall 113. The two first sidewalls 111 are arranged opposite each other along the circumference of the roller 20, defining the lateral width of the water passage cavity 11c. The two second sidewalls 112 are arranged opposite each other along the axial direction of the roller 20, defining the axial length of the water passage cavity 11c.

[0084] One second sidewall 112 is connected to one axial end of the two first sidewalls 111, and the other second sidewall 112 is connected to the other axial end of the two first sidewalls 111. A top wall 113 is connected to the top of the two first sidewalls 111 and the two second sidewalls 112 away from the first opening 11b, and together with the two first sidewalls 111 and the two second sidewalls 112, defines the water passage cavity 11c. The top wall 113 is opposite to the first opening 11b, and together they define the height and volume of the water passage cavity 11c. The two first sidewalls 111, the two second sidewalls 112, and the top wall 113 support and constrain each other, forming a stable shell structure.

[0085] The outer shell 12 is located on the side of the two first side walls 111, the two second side walls 112, and the top wall 113 away from the first opening 11b. The first water passage hole 11a is located on at least one of the first side walls 111, the second side walls 112, and the top wall 113. The water passage hole can be flexibly selected to be opened on the first side wall 111, the second side wall 112, or the top wall 113 according to the water distribution in the interlayer space 10a. When water enters the water passage cavity 11c from the interlayer space 10a through the water passage hole, its flow path is guided and restricted by these walls, forming a relatively orderly flow space.

[0086] In some embodiments, the distance between the two first sidewalls 111 along the circumference of the roller 20 decreases in the direction opposite to the first opening 11b, forming a stable arched structure with a narrower top and a wider bottom. As mentioned earlier, the outer shell 12 can tightly wrap around the mounting bracket 11. For this "narrower top and wider bottom" structure, the outer shell 12 can also be designed into a corresponding shape during manufacturing. When the top wall 113 of the lifting rib 10 lifts the clothes, it is subjected to a huge radially inward impact force along the roller 20. This force is transmitted to the two first sidewalls 111. Since the first sidewalls 111 are inclined, this inward impact force is decomposed into two components: a pressure perpendicular to the sidewall and a downward component along the sidewall, which can improve the lifting rib 10's ability to resist the impact of the clothes and the vibration of the roller 20.

[0087] In some embodiments, the distance between the two second sidewalls 112 along the axial direction of the roller 20 decreases in the direction opposite to the first opening 11b. When the roller 20 rotates, the lifting ribs 10 are subjected not only to radial impact forces but also to axial shear forces and torques generated by the irregular axial movement of the clothing. The two inclined second sidewalls 112, which are narrower at the top and wider at the bottom, can also decompose the axial shear forces. Part of the force is borne by the inclined sidewalls as pressure, while the other part is converted into a downward component force along the sidewalls and transmitted to the robust roller 20.

[0088] Both the first sidewall 111 and the second sidewall 112 mentioned above can provide a natural flow slope for the water flow in the interlayer space 10a, and the water flow can flow into the water passage cavity 11c through the first water passage hole 11a along this flow slope.

[0089] In some embodiments, the surface of the first sidewall 111 facing the outer shell 12 and the surface of the second sidewall 112 facing the outer shell 12 are smoothly connected, and / or, the surface of the first sidewall 111 facing the outer shell 12 and the surface of the top wall 113 facing the outer shell 12 are smoothly connected, and / or, the surface of the second sidewall 112 facing the outer shell 12 and the surface of the top wall 113 facing the outer shell 12 are smoothly connected.

[0090] In this embodiment, any two adjacent pairs of the first sidewall 111, the second sidewall 112, and the top wall 113 are smoothly connected, i.e., the outer surface of the mounting bracket 11 features a continuous curved surface and rounded corners. At the three pairs of intersecting edges of the first sidewall 111, the second sidewall 112, and the top wall 113, instead of forming sharp edges, they are connected by smooth curved surfaces (such as arc surfaces). This allows stress to be smoothly and evenly distributed and transmitted along the curved surface, avoiding the formation of stress singularities in localized areas. This significantly reduces fatigue cracks caused by stress concentration, enabling the lifting rib 10 to maintain structural integrity under long-term, repeated loads, greatly improving the product's durability and reliability.

[0091] Furthermore, the smoothly transitioning curved surface provides a continuous fitting reference for the housing 12, allowing the housing 12 to be machined into a shape that perfectly matches the curved surface of the mounting bracket 11, meaning that any two adjacent walls of the housing 12 smoothly transition and connect. During assembly, the housing 12 can smoothly fit along the smooth curved surface without wrinkles, warping, or dead corners that cannot fit properly at the edges. This significantly reduces the risk of clothes being snagged or damaged during washing and drying, which is especially important for delicate fabrics such as silk, lace, and wool.
