Description

Technical Field

[0001] This application relates to the field of dynamic balancing technology for top-opening garment processing equipment, and more particularly to a lifting rib and a top-opening garment processing equipment. Background Technology

[0002] Top-loading garment processing equipment, also known as top-loading drum processing equipment, differs from common front-loading drum processing equipment. The cover of the top-loading garment processing equipment is located on the top of the machine body, and the inner drum has a garment inlet and a door connected to the inlet. Due to the weight of the inner drum door cover itself, the inner drum tends to become eccentric when rotating. Summary of the Invention

[0003] This application provides a lifting rib and a top-opening garment processing device. The lifting rib stores washing water when the top-opening garment processing device is washing a load, so as to counteract the eccentricity of the inner drum caused by the door cover, ensure the dynamic balance of the inner drum, and gradually discharge the internal washing water during the dehydration process.

[0004] The lifting rib is used in a top-opening garment processing device, which includes an inner cylinder with a garment inlet on its periphery and a door hinged to the inlet to close it. The lifting rib includes a shell with a liquid storage chamber, and a liquid inlet structure and a liquid outlet structure installed on the shell. The shell is installed on the inner wall of the inner cylinder. The liquid inlet structure is configured to allow water to enter the liquid storage chamber, and the liquid outlet structure is configured to discharge the liquid in the liquid storage chamber after the inner cylinder reaches a certain rotation speed.

[0005] Based on the lifting ribs in the embodiments of this application, during the washing load process, the washing water in the top-opening garment processing equipment enters the liquid storage chamber through the liquid inlet structure to increase the weight of the lifting ribs. This allows the lifting ribs containing washing water inside to offset at least part of the eccentricity of the inner drum caused by the door cover, resulting in better dynamic balance of the inner drum. In the initial stage of dehydration, the better dynamic balance of the inner drum improves the dehydration success rate and the rate of achieving the maximum speed of the top-opening garment processing equipment.

[0006] In some embodiments of this application, the housing has a top end near the axis of the inner cylinder and a bottom end away from the axis of the inner cylinder, the liquid inlet structure is installed at the top end, and the liquid outlet structure is installed at the bottom end.

[0007] Based on the above embodiments, the liquid inlet structure is installed at the top of the shell near the inner cylinder axis, making it easier for washing water in the top-opening garment processing equipment to enter the storage chamber through the liquid inlet structure. According to the centrifugal force formula F=mω2r, where F represents centrifugal force, m represents the mass of the object, ω represents the angular velocity, and r represents the distance between the object and the axis of rotation, under the premise that m and ω are fixed, the farther the drain structure is from the inner cylinder axis, the greater the centrifugal force on the drain structure. When the drain structure is installed at the bottom of the shell away from the inner cylinder axis, the drain structure is farthest from the inner cylinder axis, and the centrifugal force it receives is the greatest, making the drain structure easier to open.

[0008] In some embodiments of this application, the drainage structure is configured as an elastic membrane with slits, which deforms to open the slits after the inner cylinder reaches a certain rotational speed; or,

[0009] The drainage structure is configured as a single-way pressure valve, which is activated after the inner cylinder reaches a certain rotational speed.

[0010] Based on the above embodiments, during the rotation of the inner cylinder and the lifting ribs, the washing water in the storage chamber is subjected to centrifugal force. When the external force exerted by the washing water on the elastic membrane exceeds the force required for the elastic membrane to deform, the elastic membrane deforms, and the slit on the elastic membrane opens. Under the action of centrifugal force, the washing water in the storage chamber is discharged from the storage chamber through the slit. Similarly, when the drainage structure is configured as a single-way pressure valve, during the rotation of the inner cylinder and the lifting ribs, the washing water in the storage chamber is subjected to centrifugal force. When the external force exerted by the washing water on the single-way pressure valve exceeds the force required for the single-way pressure valve to open, the single-way pressure valve opens, and the washing water in the storage chamber is discharged from the storage chamber under the action of centrifugal force.

[0011] In some embodiments of this application, the liquid inlet structure includes a guide column and a liquid inlet hole. The guide column is installed on the inner wall of the liquid storage cavity and extends toward the bottom end. The liquid inlet hole extends toward the bottom end and passes through the top end and the guide column in sequence.

[0012] Based on the above embodiments, after the washing water enters the storage chamber through the inlet, because the guide column is installed on the inner wall of the storage chamber and extends towards the bottom, even when the inner cylinder drives the lifting rib to rotate to a position where the bottom is on top and the top is below, the portion of the liquid level in the storage chamber that is lower than the guide column and farther from the top will not leak out of the storage chamber from the inlet. Furthermore, due to centrifugal force, the washing water in the storage chamber is "squeezed" to the side near the inner cylinder wall, making it less likely to leak out from the inlet.

[0013] In some embodiments of this application, the diameter of the inlet hole gradually decreases from the top end to the bottom end.

[0014] Based on the above embodiments, the gradually narrowing inlet diameter forms a funnel shape. This funnel-shaped inlet guides the water flow as it enters the storage chamber, increasing the flow velocity due to the narrowing of the inlet diameter. According to Bernoulli's principle, fluid pressure decreases as flow velocity increases, which helps water flow into the storage chamber more quickly. Furthermore, the continuously narrowing inlet, forming an inlet of a certain length, with smooth walls, reduces fluid friction and resistance, further guiding the water flow.

[0015] In some embodiments of this application, the lifting rib further includes a filter element, which is installed on the outer wall of the housing and covers the liquid inlet structure.

[0016] Based on the above embodiments, the filter element can prevent tiny impurities in the washing water from entering the liquid storage chamber, such as lint.

[0017] In some embodiments of this application, the housing includes a main body and a bottom shell, the main body and the bottom shell surround the liquid storage cavity, the bottom shell is installed on the inner wall of the inner cylinder, the liquid inlet structure is installed on the main body, and the liquid outlet structure is installed on the bottom shell.

[0018] Based on the above embodiments, the main body and the bottom shell are processed separately. After the processing of both is completed, the main body and the bottom shell are connected, and the connecting part and the bottom shell can enclose the liquid storage cavity.

[0019] In some embodiments of this application, there are multiple liquid inlet structures, and the multiple liquid inlet structures are spaced apart along the axial direction of the inner cylinder.

[0020] Based on the above embodiments, multiple water inlet structures can accelerate the speed at which washing water enters the storage chamber from the inner drum. At the same time, the multiple water inlet structures are spaced apart along the axial direction of the inner drum, so that the washing water entering the storage chamber can be evenly distributed in the storage chamber, thereby ensuring the balance of the inner drum along the axial direction.

[0021] In some embodiments of this application, there are multiple drainage structures, which are installed on the edge of the bottom shell and distributed at intervals along the circumference of the bottom shell.

[0022] Based on the above embodiments, multiple drainage structures can discharge the washing water in the storage chamber more quickly. The multiple drainage structures are installed at the edge of the bottom shell, so that the washing water in the storage chamber can be discharged in a dispersed manner, reducing the impact intensity of the washing water discharged from the storage chamber on the outer drum of the top-opening garment processing equipment. The drainage structures are distributed circumferentially along the bottom shell, so that the washing water in the storage chamber is discharged as evenly as possible. That is, the washing water that has not been discharged from the storage chamber is still evenly distributed in the storage chamber, ensuring the balance of the inner drum while draining the washing water in the storage chamber.

[0023] In some embodiments of this application, the lifting rib further includes a reinforcing rib, which is located within the liquid storage cavity and installed on the inner wall of the main body.

[0024] Based on the above embodiments, the structure of the lifting rib is enhanced by reinforcing ribs. In addition, when the inner cylinder drives the lifting rib to rotate, the washing water in the liquid storage cavity is forced to move within the liquid storage cavity. The reinforcing ribs distributed in various parts of the liquid storage cavity can disperse the external force applied to the lifting rib when the washing water moves within the liquid storage cavity.

[0025] Secondly, embodiments of this application provide a top-opening garment processing device, including an inner cylinder and lifting ribs as described above. The inner cylinder is configured to rotate about an axis extending in a horizontal or inclined direction. The inner cylinder has a garment inlet on its periphery, and a door cover that can close the garment inlet is hinged at the garment inlet. The lifting ribs are installed on the inner wall of the inner cylinder.

[0026] Based on the above embodiments, due to the aforementioned lifting ribs, during the washing load process, the washing water enters the storage chamber through the liquid inlet structure of the top-opening garment processing equipment to increase the weight of the lifting ribs. This allows the lifting ribs containing washing water inside to offset at least part of the eccentricity of the inner drum caused by the door cover, resulting in better dynamic balance of the inner drum. During the initial stage of dehydration, the better dynamic balance of the inner drum improves the dehydration success rate and the rate of achieving the maximum rotation speed of the top-opening garment processing equipment.

[0027] In some embodiments of this application, the lifting ribs are arranged opposite to the axis of the door cover about the inner cylinder.

[0028] Based on the above embodiments, since the inner drum of the top-opening garment processing equipment must be hinged to the door cover, the door cover causes the inner drum to be eccentric during rotation. Therefore, the lifting ribs are set opposite to the axis of the door cover about the inner drum so that the lifting ribs can balance the eccentricity of the inner drum caused by the door cover to the greatest extent.

Detailed Implementation

[0035] 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.

[0036] Top-loading washing machines, also known as top-loading drum washing machines, have a diagonal eccentricity at the door due to the weight of the inner drum itself, compared to conventional drum washing machines. Assuming the top-loading washing machine only has one lifting rib on the opposite side of the door, when the drum is empty, the actual eccentricity of the inner drum is approximately equal to the weight of the door minus the weight of the lifting rib. In actual washing processes, top-loading washing machines have long suffered from excessive eccentricity at the door, severely impacting noise levels and spin-drying success rates during the washing and spin-drying stages.

[0037] In previous developments, the inventors attempted to improve the inner cylinder's eccentricity by increasing the volume and density of the lifting ribs to enhance their counterweight. However, large lifting ribs encroach on the inner cylinder space, causing the load to be pushed towards the door cover, which actually worsens the eccentricity under full load. Furthermore, large lifting ribs significantly increase material costs. During high-speed operation, the substantial weight of the lifting ribs, along with the door cover, causes reverse stretching of the inner cylinder, resulting in deformation.

[0038] In the first aspect, the embodiments of this application provide a lifting rib 10, which can store washing water during the washing load process of the top-opening garment processing equipment to increase the weight of the lifting rib 10, so that the lifting rib 10 can counteract the eccentricity of the inner drum 20 caused by the door cover 21 as much as possible, thereby ensuring the dynamic balance of the inner drum 20 during rotation, reducing noise during the washing and dehydration stages and improving the dehydration success rate of the top-opening garment processing equipment.

[0039] The top-loading garment processing device in this application embodiment can be a top-loading drum washing machine, a top-loading drum washer-dryer combo, etc. In this application embodiment, a top-loading drum washing machine is used as an example to describe the top-loading garment processing device.

[0040] Please refer to Figures 1 to 3 As shown, the lifting rib 10 is applied to a top-opening garment processing device. The top-opening garment processing device includes an inner cylinder 20. The inner cylinder 20 has a garment inlet on its periphery, and a door cover 21 that can close the garment inlet is hinged at the garment inlet. The lifting rib 10 includes a housing 11 with a liquid storage chamber 116, and a liquid inlet structure 12 and a liquid outlet structure 13 installed on the housing 11. The housing 11 is installed on the inner wall of the inner cylinder 20. The liquid inlet structure 12 is configured to allow water to enter the liquid storage chamber 116, and the liquid outlet structure 13 is configured to discharge the liquid in the liquid storage chamber 116 after the inner cylinder 20 reaches a certain rotation speed.

[0041] The inner drum 20 of the top-opening garment processing equipment differs from that of conventional drum-type garment processing equipment, which has one end closed and the other end open as a loading port. To allow for loading and unloading from the top of the inner drum 20, the inner drum 20 is closed at both ends, with a loading port on its peripheral wall. This loading port is used by the user to load or unload the garment into the machine assembly. A hinged cover 21 is attached to the inner drum 20 to close the loading port. When the top-opening garment processing equipment is operating, the cover 21 closes the loading port to confine the load within the inner drum 20. In this embodiment, the load can be various items that can be washed, cared for, or dried by the top-opening garment processing equipment.

[0042] The lifting ribs 10 are used to help lift and tumble the load during the washing process. During the rotation of the inner drum, the lifting ribs 10 can lift the clothes to a certain height and then let the clothes fall down to help the friction between the clothes. At the same time, the lifting ribs 10 can change the flow direction and intensity of the washing water, so that the water and detergent can penetrate into the clothes more effectively.

[0043] In this embodiment, the material, shape, and size of the lifting ribs 10 are not limited. The size of the lifting ribs 10 can be set according to the size of the inner tub 20. The function of the lifting ribs 10 can be selected according to user needs or the designer's focus. For example, they can be elastic ribs that continuously agitate the water flow to generate oscillating water waves, washboard-type lifting ribs that simulate the action of a mallet, or S-shaped lifting ribs 10 that improve the uniformity of washing. In this embodiment, the lifting ribs 10 can be made of either stainless steel or polymer plastic. Stainless steel lifting ribs 10 have good corrosion resistance and durability. Polymer plastic lifting ribs 10, due to their high frictional resistance, are more suitable for lifting and tumbling clothes, and can provide better cleaning results.

[0044] The liquid storage cavity 116 is used to store washing water. In this application embodiment, the size and shape of the liquid storage cavity 116 are not limited, as long as the liquid storage cavity 116 can store washing water. In some embodiments of this application, the centroid of the liquid storage cavity 116 coincides with the center of gravity of the lifting rib 10. In this way, after the liquid storage cavity 116 is filled with washing water, the center of gravity of the washing water in the liquid storage cavity 116 coincides with the center of gravity of the lifting rib 10, so as to ensure the balance of the inner cylinder 20 during the rotation process.

[0045] In this embodiment, the specific rotation speed is not specifically limited. It can be understood that, according to the working principle of the dehydration of the clothing processing equipment, the drain structure 13 can be configured to start draining the liquid in the storage chamber 116 after the inner drum 20 reaches the dehydration speed; or the drain structure 13 can be configured to start draining the liquid in the storage chamber 116 after the inner drum 20 is in the dehydration stage (the rotation speed of the inner drum 20 is greater than or equal to the dehydration speed).

[0046] Based on the lifting rib 10 of this application embodiment, during the washing load process of the top-opening garment processing equipment, washing water enters the liquid storage chamber 116 through the liquid inlet structure 12 to increase the weight of the lifting rib 10. This allows the lifting rib 10, containing washing water, to counteract at least part of the eccentricity of the inner drum 20 caused by the door cover 21, resulting in better dynamic balance of the inner drum 20. This leads to less noise during the washing stage, reduces the probability of eccentricity during washing, and lowers the eccentricity rate of the inner drum 20 during the eccentricity detection stage before spin-drying. This allows the inner drum 20 to reach the spin-drying stage more smoothly. During the initial spin-drying stage, due to the better dynamic balance of the inner drum 20, the probability of the inner drum 20 hitting the drum during rotation is lower, allowing it to accelerate to the spin-drying speed more smoothly and improving the spin-drying success rate of the top-opening garment processing equipment. Furthermore, during the high-speed rotation of the inner drum, the washing water in the lifting rib 10 is continuously thrown out of the liquid storage chamber 116, reducing the stretching of the inner drum and lowering its deformation rate.

[0047] In addition, the lifting rib 10 implemented in this application uses less material, which can reduce the manufacturing cost of the lifting rib 10 and reduce the weight of the lifting rib 10. When the inner cylinder 20 rotates at high speed, the lighter lifting rib 10 can further reduce the stretching of the lifting rib 10 on the inner cylinder 20, that is, reduce the deformation of the inner cylinder 20.

[0048] When the lifting rib 10 is made of polymer plastic, since the density of water is greater than that of polymer plastic, the volume of the lifting rib 10 can be smaller. Even when the inner cylinder 20 is fully loaded, the load can be more evenly distributed within the inner cylinder 20, thus improving the dynamic balance problem when the inner cylinder 20 is fully loaded.

[0049] In some embodiments of this application, the housing 11 has a top end 114 near the axis of the inner cylinder 20 and a bottom end 115 away from the axis of the inner cylinder 20, the liquid inlet structure 12 is installed at the top end 114, and the liquid outlet structure 13 is installed at the bottom end 115.

[0050] The liquid inlet structure 12 is installed at the top 114 of the main body near the axis of the inner drum 20, making it easier for the washing water in the top-opening garment processing equipment to enter the storage chamber 116 through the liquid inlet structure 12. According to the centrifugal force formula F=mω2r, where F represents centrifugal force, m (in this application, the total weight of the lifting rib 10 and the washing water in the storage chamber 116) represents the mass of the object, ω represents the angular velocity (in this application, the angular velocity of the inner drum 20 rotating around its own axis), and r represents the distance between the object and the axis of rotation (in this embodiment, the axis of the inner drum 20). Under the premise that m and ω are fixed, the farther the drain structure 13 is from the axis of the inner cylinder 20, the greater the centrifugal force on the drain structure 13. Similarly, the closer the washing water in the storage cavity 116 is to the drain structure 13, the greater the centrifugal force it experiences. Therefore, the external force applied to the drain structure 13 is greater. At this time, the drain structure 13 is farthest from the axis of the inner cylinder 20, the centrifugal force on the washing water in the storage cavity 116 is the greatest, and the external force that the washing water in the storage cavity 116 can apply to the drain structure 13 is the greatest, making the drain structure 13 easier to open.

[0051] Please refer to Figure 2 As shown, in some embodiments of this application, the drain structure 13 is configured as an elastic membrane with slits. After the inner cylinder 20 reaches a certain rotational speed, the elastic membrane can deform to open the slits. During the rotation of the inner cylinder 20 and the lifting rib 10, the washing water in the storage chamber 116 is subjected to centrifugal force. When the external force exerted by the washing water on the elastic membrane exceeds the external force required for the elastic membrane to deform, the elastic membrane deforms, and the slits on the elastic membrane open. Under the action of centrifugal force, the washing water in the storage chamber 116 is discharged from the storage chamber 116 through the slits. It is understood that the slits in the embodiments of this application can be configured in any shape, such as a cross shape, a straight slit, a star-shaped slit, etc.

[0052] In some other embodiments of this application, the drain structure 13 is configured as a single-way pressure valve (not shown in the figure). The single-way pressure valve is activated after the inner cylinder 20 reaches a certain rotational speed. The working principle of the single-way pressure valve is that when fluid flows in from the inlet end of the single-way pressure valve and its pressure is greater than the pressure set by the closing mechanism, the valve will automatically open to allow fluid to pass through. When the pressure at the inlet end is lower than the pressure at the outlet end or drops below the pressure set by the closing mechanism, the valve will quickly close to prevent the fluid from flowing backward. Therefore, after the drain structure 13 is configured as a single-way pressure valve, during the process of the inner cylinder 20 driving the lifting rib 10 to rotate, the washing water in the storage chamber 116 is subjected to centrifugal force. When the external force of the washing water applied to the single-way pressure valve is greater than the external force required for the single-way pressure valve to be activated, the single-way pressure valve is activated, and the washing water in the storage chamber 116 is discharged from the storage chamber 116 under the action of centrifugal force.

[0053] Considering the rotational speed of the inner drum 20 in each stage of the top-loading garment processing equipment, it can be understood that the rotational speed of the inner drum 20 during the washing stage is lower than that during the spin-drying stage. Therefore, the centrifugal force generated by the washing water in the storage chamber 116 during the spin-drying stage is greater than that generated during the washing stage. Thus, by appropriately setting the opening pressure of the single-way pressure valve, it can be ensured that washing water is stored in the storage chamber 116 during the washing stage and gradually decreases during the spin-drying stage. The single-way pressure valve in this embodiment can be a spring-loaded single-way pressure valve, a disc-type single-way pressure valve, or a swing-type single-way pressure valve, etc.

[0054] Please refer to Figure 3 As shown, in some embodiments of this application, the liquid inlet structure 12 includes a guide column 121 and a liquid inlet hole 122. The guide column 121 is installed on the inner wall of the liquid storage cavity 116 and extends toward the bottom end 115. The liquid inlet hole 122 extends toward the bottom end 115 and passes through the top end 114 and the guide column 121 in sequence.

[0055] The guide column 121 is used to guide the washing water into the storage chamber 116 during the water inlet stage of the top-opening garment processing equipment and when the lifting rib 10 is immersed in water during rotation. It is understood that the guide column 121 has a certain length to guide the water flow, making it easier for the washing water to enter the storage chamber 116 through the inlet hole 122. In this embodiment, the guide column 121 can be integrally formed with the housing 11.

[0056] After the washing water enters the storage chamber 116 through the inlet 122, the guide column 121 is installed on the inner wall of the storage chamber 116 and extends towards the bottom 115. Even when the inner cylinder 20 rotates the lifting rib 10 to a position where the bottom 115 is on top and the top 114 is below, the portion of the liquid level in the storage chamber 116 that is lower than the end of the guide column 121 away from the top 114 will not leak out of the storage chamber 116 from the inlet 122. In addition, due to centrifugal force, the washing water in the storage chamber is "squeezed" to the side near the inner cylinder wall, making it less likely to leak out from the inlet.

[0057] The liquid inlet 122 is used to connect the liquid storage chamber 116 and the outside of the shell 11. In this embodiment, the liquid inlet 122 can be configured in any shape; for example, it can be configured as a constant-diameter channel or a variable-diameter pipe. In some embodiments of this application, the diameter of the liquid inlet 122 gradually decreases from the top end 114 to the bottom end 115.

[0058] The gradually narrowing inlet diameter forms a funnel shape. This funnel-shaped inlet guides the water flow into the storage chamber, increasing the flow velocity as the inlet diameter narrows. According to Bernoulli's principle, fluid pressure decreases as flow velocity increases, which helps water flow into the storage chamber more quickly. Even when the inner cylinder rotates with the lifting ribs at the bottom and top, water molecules at the narrow opening of the inlet are attracted by surrounding molecules, causing them to accumulate and form a raised water surface. This raised surface makes it difficult for water to flow out of the narrow opening.

[0059] It is understood that there are multiple flow guide columns 121 and liquid inlet holes 122 in the embodiments of this application, and the liquid inlet holes 122 and flow guide columns 121 correspond one-to-one.

[0060] In some embodiments of this application, the lifting rib 10 further includes a filter (not shown in the figure), which is installed on the outer wall of the housing 11 and covers the liquid inlet structure 12. Since the load is clothing such as sweaters, some of the lint and other debris on the sweaters will inevitably fall into the washing water during the washing process. The filter can prevent debris in the washing water from entering the liquid inlet hole 122 and the liquid storage chamber 116, and prevent impurities in the washing water from clogging the liquid inlet hole 122 and the drainage structure, thereby improving the reliability of the lifting rib 10.

[0061] In this embodiment, there can be multiple filter elements, each corresponding to one of the liquid inlet holes 122. The filter elements are disposed within the liquid inlet holes 122 to prevent damage to the filter elements caused by the load during the rotation of the inner cylinder 20. In this embodiment, there can also be a single filter element. The housing 11 has a receiving groove corresponding to the filter element, which connects multiple liquid inlet holes 122. The filter element is fixed in the receiving groove and extends along the length of the receiving groove to cover the openings formed at the top 114 of all liquid inlet holes 122. At the same time, the filter element being disposed within the receiving groove can prevent damage to the filter element caused by the load during the rotation of the inner cylinder 20.

[0062] The filter element is used to filter impurities in the washing water entering the liquid storage chamber 116. In this embodiment, the filter element can be configured as a sponge pad, non-woven fabric, etc. In addition, when the inner cylinder 20 drives the lifting rib 10 to rotate to the state where the bottom end 115 is on top and the top end 114 is below, if the liquid level of the washing water in the liquid storage chamber 116 is higher than the end of the guide column 121 away from the top end 114, a small amount of washing water in the liquid storage chamber 116 will flow out of the liquid storage chamber 116 through the liquid inlet hole 122 to rinse the filter element, and wash the impurities on the side of the filter element away from the liquid storage chamber 116 into the washing water in the inner cylinder 20, and finally discharge it with the washing water from the top-opening garment processing equipment.

[0063] Please refer to Figure 3As shown, in some embodiments of this application, the housing 11 includes a main body 111 and a bottom shell 112. The main body 111 is connected to the bottom shell 112 and surrounds a liquid storage cavity 116. The bottom shell 112 is installed on the inner wall of the inner cylinder 20. The liquid inlet structure 12 is installed on the main body 111, and the liquid outlet structure 13 is installed on the bottom shell 112. It can be understood that, combined with the above-mentioned housing 11 having a top end 114 near the axis of the inner cylinder 20 and a bottom end 115 away from the axis of the inner cylinder 20, the liquid inlet structure 12 is installed on the top end 114, the liquid outlet structure 13 is installed on the bottom end 115, the main body 111 has a top end 114, and the bottom shell 112 has a bottom end 115.

[0064] In this way, both the main body 111 and the bottom shell 112 can be machined separately. After both are machined, the main body 111 and the bottom shell 112 are connected, and the connecting part and the bottom shell 112 can then enclose the liquid storage cavity 116. This process is less difficult than directly machining the liquid storage cavity 116 on the lifting rib 10. Understandably, at this time, a sealed connection is required between the main body 111 and the bottom shell 112. The sealed connection can be achieved by placing a sealing gasket between the two and connecting them with screws or other means.

[0065] Please refer to Figure 1 As shown, in some embodiments of this application, there are multiple liquid inlet structures 12, and the multiple liquid inlet structures 12 are spaced apart along the axial direction of the inner cylinder 20.

[0066] Multiple water inlet structures can accelerate the speed at which washing water in the inner drum 20 enters the liquid storage chamber 116. At the same time, multiple water inlet structures are spaced apart along the axial direction of the inner drum 20, so that the washing water entering the liquid storage chamber 116 can be evenly distributed in the liquid storage chamber 116, thereby ensuring the balance of the inner drum 20 along the axial direction.

[0067] Please refer to Figure 2 As shown, in some embodiments of this application, there are multiple drainage structures 13, which are installed on the edge of the bottom shell 112 and are distributed at intervals along the circumference of the bottom shell 112.

[0068] Multiple drainage structures 13 can drain the washing water in the storage chamber 116 more quickly. Multiple drainage structures 13 are installed at the edge of the bottom shell 112 so that the washing water in the storage chamber 116 can be discharged in a dispersed manner, reducing the impact intensity of the washing water discharged from the storage chamber 116 on the outer drum of the top-opening garment processing equipment.

[0069] The drainage structure is distributed circumferentially along the bottom shell 112, so that the washing water in the liquid storage chamber 116 is discharged as evenly as possible. That is, the washing water that is not discharged in the liquid storage chamber 116 is still evenly distributed in the liquid storage chamber 116, and the balance of the inner cylinder 20 is maintained while the washing water in the liquid storage chamber 116 is discharged.

[0070] Please refer to Figure 3 As shown, in some embodiments of this application, the lifting rib 10 further includes a reinforcing rib 113. The reinforcing rib 113 is located within the liquid storage cavity 116 and is installed on the inner wall of the main body 111 and / or the inner wall of the bottom shell 112. The reinforcing rib 113 strengthens the structure of the lifting rib 10. In addition, when the inner cylinder 20 drives the lifting rib 10 to rotate, the washing water in the liquid storage cavity 116 is forced to move within the liquid storage cavity 116. The reinforcing ribs 113 distributed throughout the liquid storage cavity 116 can disperse the external force applied to the lifting rib 113 when the washing water moves within the liquid storage cavity 116. It can be understood that in some embodiments of this application, the reinforcing rib 113 can divide the liquid storage cavity 116 into multiple liquid storage sub-cavities to further reduce the movement of washing water within the liquid storage cavity 116.

[0071] In this application, the shape of the reinforcing rib 113 is not limited. In some embodiments of this application, the reinforcing rib 113 and the main body 111 are made of the same material and are integrally formed.

[0072] Secondly, please refer to Figure 4 As shown, this application embodiment provides a top-opening garment processing device. The top-opening garment processing device includes an inner cylinder 20 and the above-mentioned lifting ribs 10. The inner cylinder 20 is configured to rotate about an axis extending in a horizontal or inclined direction. The inner cylinder 20 has a garment inlet on its periphery, and a door cover 21 that can close the garment inlet is hinged at the garment inlet. The lifting ribs 10 are installed on the inner wall of the inner cylinder 20.

[0073] Based on the above embodiments, due to the aforementioned lifting ribs 10, during the washing load process of the top-opening garment processing equipment, the washing water enters the liquid storage chamber 116 through the liquid inlet structure 12 to increase the weight of the lifting ribs 10. This allows the lifting ribs 10, which contain washing water, to counteract at least part of the eccentricity of the inner drum 20 caused by the door cover 21, resulting in better dynamic balance of the inner drum 20. Consequently, the inner drum 20 generates less noise during the washing and spin-drying stages. During the initial spin-drying stage, due to the better dynamic balance of the inner drum 20, the probability of the inner drum 20 hitting the drum during rotation is reduced, allowing it to accelerate to the spin-drying speed more smoothly and improving the spin-drying success rate of the top-opening garment processing equipment.

[0074] In addition, the lifting rib 10 implemented in this application uses less material, which can reduce the manufacturing cost of the lifting rib 10. When the lifting rib 10 is made of polymer plastic, since the density of water is greater than that of polymer plastic, the volume of the lifting rib 10 can be smaller. Even when the inner cylinder 20 is fully loaded, the load can be more evenly distributed in the inner cylinder 20, which improves the dynamic balance problem when the inner cylinder 20 is fully loaded.

[0075] In some embodiments of this application, the lifting rib 10 and the door cover 21 are arranged opposite to each other about the axis of the inner drum 20. Since the inner drum 20 of the top-opening garment handling device must be hinged to the door cover 21, the door cover 21 causes the inner drum 20 to become eccentric during rotation. Therefore, by arranging the lifting rib 10 and the door cover 21 opposite to each other about the axis of the inner drum 20, the centrifugal force generated by the lifting rib 10 when the inner drum 20 rotates is aligned with and opposite in direction to the centrifugal force generated by the door cover 21 when the inner drum 20 rotates. This allows the lifting rib 10 to balance the eccentricity of the inner drum 20 caused by the door cover 21 to the greatest extent possible. To ensure that the lifting rib 10 can accurately balance the centrifugal force generated by the door cover 21, in some embodiments of this application, the center of the lifting rib 10 and the center of the door cover 21 are symmetrical about the axis of the inner drum 20.

[0076] At this time, there is one lifting rib 10. The sum of the weight of the lifting rib 10 itself and the weight of the washing water in the liquid storage cavity 116 when it is completely filled with washing water is equal to the weight of the door cover 21. This is so that the liquid storage cavity 116 can completely balance the eccentricity of the inner cylinder 20 caused by the door cover 21 after it is filled with washing water. Even if the liquid storage cavity 116 is not completely filled with washing water, the lifting rib 10 can still balance the partial eccentricity of the inner cylinder 20 caused by the door cover 21.

[0077] It is understandable that, in order to balance the washing capacity of the top-loading garment processing equipment and the eccentricity of the inner drum 20 caused by the door cover 21, the number of lifting ribs 10 can be multiple. Multiple lifting ribs 10 can improve the washing capacity of the top-loading garment processing equipment. Multiple lifting ribs 10 can be arranged as a whole, opposite to the axis of the inner drum 20 with respect to the door cover 21. That is, multiple lifting ribs 10 work together to balance the eccentricity of the inner drum 20 caused by the door cover 21. In this case, the resultant force of the centrifugal force generated by the multiple lifting ribs 10 when the inner drum 20 rotates should be on the same straight line and in the opposite direction to the centrifugal force generated by the door cover 21 when the inner drum 20 rotates. To ensure that the lifting ribs 10 can accurately balance the centrifugal force generated by the door cover 21, in some embodiments of this application, the center of the multiple lifting ribs 10 as a whole and the center of the door cover 21 are symmetrical about the axis of the inner drum 20.
