Description

Technical Field

[0001] This application relates to the field of clothing processing equipment technology, and more specifically, to a cylindrical assembly and a clothing processing device. Background Technology

[0002] There are now many clothing handling devices on the market with different functions and appearances, such as washing machines and dryers. As a commonly used clothing handling device, washing machines come in a wide variety of types. According to the installation method, they include floor-standing washing machines, wall-mounted washing machines, and countertop washing machines; according to the working principle, they include top-loading washing machines and front-loading washing machines.

[0003] In the relevant technical field, when a washing machine is spinning, the water that is spun out easily forms a water ring under the action of centrifugal force. In washing machines with drying functions, there are drying air outlets on the drum. The water rings formed during spinning can easily hit the side wall of the air outlet, creating a turbulent effect and affecting the airflow. Furthermore, excessive water accumulation can easily cause odors over a long period of time, affecting normal use by the user. Utility Model Content

[0004] This application provides a tubular assembly and a clothing handling device that can prevent water from flowing towards the air outlet and ensure the air outlet effect.

[0005] In a first aspect, embodiments of this application provide a cylindrical assembly, which includes an outer cylinder, an inner cylinder, and a water-blocking structure; the outer cylinder is provided with an air outlet; the inner cylinder is rotatably disposed inside the outer cylinder; the water-blocking structure is connected to the outer cylinder, the water-blocking structure is disposed near the air outlet, and is used to direct the water flowing toward the air outlet to outside the opening area of ​​the air outlet.

[0006] In some embodiments, the water-blocking structure extends from the inner wall of the outer cylinder to the opening area of ​​the air outlet.

[0007] In some embodiments, the water-blocking structure covers at least a portion of the opening area of ​​the air outlet facing the inner cylinder.

[0008] In some embodiments, the inner cylinder rotates about its central axis relative to the outer cylinder, and the direction of rotation of the inner cylinder is the same as the direction of extension of the water-blocking structure from the inner wall of the outer cylinder to the air outlet opening area.

[0009] In some embodiments, the water-blocking structure is located upstream of the air outlet along the rotation direction of the inner cylinder.

[0010] In some embodiments, the width of the water-blocking structure along the axial direction of the outer cylinder is not less than the width of the outer periphery of the air outlet.

[0011] In some embodiments, the water-blocking structure and the outer cylinder are an integral structure.

[0012] In some embodiments, the water-blocking structure is provided with a flow-guiding surface, which is connected to the inner wall of the outer cylinder and faces the inner cylinder.

[0013] In some embodiments, the guide surface is a plane that slopes from the inner wall of the outer cylinder toward the inner cylinder.

[0014] In some embodiments, the plane containing the guide surface is located between a plane passing through the end of the guide surface and tangent to the outer wall of the inner cylinder and a plane passing through the end of the guide surface and the lowest point of the air outlet.

[0015] In some embodiments, the guide surface is an arc-shaped surface that curves toward the air outlet.

[0016] In some embodiments, the tangent plane at the end of the guide surface is located between a plane passing through the end of the guide surface and tangent to the outer wall of the inner cylinder and a plane passing through the end of the guide surface and the lowest point of the air outlet.

[0017] In some embodiments, the guide surface is smoothly connected to the inner wall of the outer cylinder.

[0018] In some embodiments, the cylinder assembly further includes a plurality of mounting holes, which are disposed at the connection between the water-blocking structure and / or the water-blocking structure and the inner wall of the outer cylinder, and at least some of the mounting holes are provided with defoaming components.

[0019] Secondly, embodiments of this application provide a garment processing device, which includes a housing and a cylindrical assembly as described in any one of the above claims, wherein the housing has a receiving cavity; and the cylindrical assembly is disposed within the receiving cavity.

[0020] In some embodiments, a drying assembly is also included, which is disposed within the receiving cavity and includes a drying tunnel and an air inlet communicating with the drying tunnel. An air outlet channel is provided on the outer cylinder, with one end of the air outlet channel communicating with the air outlet and the other end communicating with the air inlet of the drying tunnel.

[0021] Based on the cylindrical assembly of this application, the water-blocking structure is connected to the outer cylinder. The water-blocking structure is located near the air outlet and is used to change the direction of the water flow towards the air outlet, so that the water flow towards the air outlet is directed outside the opening area of ​​the air outlet. This covers the main path of the water flow towards the air outlet, and does not affect the hot air entering the outer cylinder from the air outlet. It provides a reliable path for the diffusion of hot air along the air outlet, without any airflow obstruction.

[0022] When the water flows with the water ring to the water-blocking structure area, the water-blocking structure exerts a lateral thrust on the water flow, breaking the integrity of the water ring. The water ring is divided at the water-blocking ribs into a non-outlet area water ring and a localized water flow in the outlet area, preventing the entire water ring from accumulating towards the outlet. After blocking the water flow, the water-blocking component guides the water flow, changing the direction of the localized water flow in the outlet area from upward along the inner wall of the outer cylinder (towards the outlet) to inward (towards the outer wall of the inner cylinder). The water flow is then completely unable to contact the side wall of the outlet, preventing backflow and water ingress at the source, thus ensuring the airflow effect of the outlet. Simultaneously, it prevents water accumulation and persistent odor within the outlet 110 during long-term use, ensuring a superior user experience. Attached Figure Description

[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] There are now many clothing handling devices on the market with different functions and appearances, such as washing machines and dryers. As a commonly used clothing handling device, washing machines come in a wide variety of types. According to the installation method, they include floor-standing washing machines, wall-mounted washing machines, and countertop washing machines; according to the working principle, they include top-loading washing machines and front-loading washing machines.

[0028] like Figure 1 As shown, this application proposes a garment processing device, including a housing and a cylindrical assembly 10. The housing has a receiving cavity, and the cylindrical assembly 10 is disposed within the receiving cavity. The housing can be a one-piece molded structure or a separate structure. In order to better support the various components inside the housing, the housing material can be a material with high structural strength, such as engineering plastics and steel.

[0029] The housing includes a base and a casing. The base is connected to the bottom of the casing. The casing has a clothing inlet, which is connected to the cylinder assembly 10. Users can put clothes into the cylinder assembly 10 through the clothing inlet. The opening shape of the clothing inlet can be circular, near-circular, or other shapes to facilitate the insertion and removal of clothes.

[0030] It should be noted that in actual use, the direction the user faces towards the clothing handling device is the front-to-back direction, the directions to the sides of the user are the left-to-right direction, and the direction at the user's height is the up-to-down direction. In this embodiment, the front panel is inclined relative to the vertical plane, and the bottom of the front panel is closer to the front of the washing machine than the top of the front panel. That is, the front panel is tilted upwards towards the user, thus better facing the user during use and facilitating the user to load and unload clothes from the clothing loading port.

[0031] The garment processing device with drying function also includes a drying component, which is set in the receiving cavity and includes a drying tunnel and an air inlet connected to the drying tunnel. An air outlet channel is provided on the outer cylinder 100, one end of which is connected to the air outlet 110 and the other end is connected to the air inlet of the drying tunnel.

[0032] The drying unit delivers continuous and stable hot air into the drum assembly 10, accelerating the evaporation of moisture from the clothes and recovering the humid airflow. After the drying unit starts, the fan generates airflow, which first passes through the heat exchange module in the drying tunnel and is heated to a preset temperature. Under the pressure of the fan, the heated air enters the air outlet channel of the outer drum 100 through the air inlet of the drying tunnel. Because the air outlet channel is sealed to the air outlet 110 of the outer drum 100, the hot air is directly transported from the air outlet 110 into the interior of the outer drum 100 along the air outlet channel, acting on the surface of the clothes to achieve moisture evaporation.

[0033] When hot air comes into contact with clothing, it absorbs moisture to form a humid airflow. Under the action of the air pressure difference inside the cylinder assembly 10 (formed by the continuous exhaust of the fan), the humid airflow flows along the inner wall of the outer cylinder 100 and re-converges at the air outlet 110, then flows back to the drying tunnel through the air outlet channel.

[0034] In tabletop washing machines, which prioritize small size and lightweight clothing processing, the core structural feature is a small diameter drum assembly 10, employing a nested design with a fixed outer drum 100 and a rotating inner drum 200. The outer drum 100, as a fixed supporting component, has an air outlet 110 on its wall for drying, serving as the key channel for hot air to enter the drum and dry the clothes. The inner wall of the air outlet 110 connects with the inner wall of the outer drum 100, forming a fixed airflow structure. The inner drum 200 dehydrates the clothes through high-speed rotation, using centrifugal force to expel water from the clothes, creating a dynamic water flow within the drum.

[0035] Because the diameter of the cylinder assembly 10 is small, when the inner cylinder 200 rotates during dehydration, the water ejected is constrained by centrifugal force and cannot spread widely inside the cylinder. Instead, it accumulates along the cylinder wall, eventually forming a complete and relatively high annular water flow, or "water ring." Due to the limited space in the cylinder assembly 10, this water ring creates a pressure environment similar to a centrifugal water pump inside the cylinder. As the inner cylinder 200 rotates, the water ring continuously gains kinetic energy and has a strong tendency to surge towards higher positions inside the cylinder, especially towards the inner wall of the air outlet 110, causing turbulence and affecting the air outlet effect. Furthermore, excessive water accumulation can easily cause odors over time, affecting normal user operation.

[0036] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3 This application proposes a cylindrical assembly 10, which in this embodiment includes an outer cylinder 100, an inner cylinder 200, and a water-blocking structure 300.

[0037] The outer cylinder 100 is provided with an air outlet 110 for connecting with the air outlet channel of the drying component to achieve the drying function. The inner cylinder 200 is rotatably disposed inside the outer cylinder 100. The technical solution of this application provides a water-blocking structure 300, which is connected to the outer cylinder 100 and is located near the air outlet 110. The water-blocking structure 300 is used to guide the water flow towards the air outlet 110 to the outside of the opening area of ​​the air outlet 110. This covers the main path of the water flow towards the air outlet 110 without affecting the hot air entering the outer cylinder 100 from the air outlet 110. It provides a reliable path for the hot air to diffuse radially along the air outlet 110. The diffusion direction of the hot air is set at an angle to the guiding direction of the water-blocking structure 300, so as not to obstruct the airflow.

[0038] To achieve the airflow guiding effect, the water-blocking structure 300 first needs to define the opening area of ​​the air outlet 110 and the area outside the opening area of ​​the air outlet 110 guided by the water-blocking structure 300. The opening area of ​​the air outlet 110 refers to the space extending from the edge of the opening of the air outlet 110 inwards. Water in this area can easily enter the air outlet 110 directly due to inertia or splash into the side wall edge of the opening. The lowest point of the air outlet 110 is the position where water is most likely to enter. The lowest point of the air outlet 110 is the lowest point of the line where the side wall of the air outlet 110 intersects with the inner wall of the outer cylinder 100.

[0039] When water flows towards the opening area of ​​the air outlet 110 under the action of centrifugal force, the water-blocking structure 300 will guide the water flow trajectory from the opening area pointing towards the air outlet 110 to outside the opening area of ​​the air outlet 110 along the surface of the water-blocking structure 300. Regardless of whether the air outlet 110 is located at the upper or lower part of the cylinder assembly 10, this guiding action can direct the water flow towards the air outlet 110 to outside the opening area of ​​the air outlet 110, thereby achieving physical isolation between the water flow and the opening of the air outlet 110.

[0040] like Figures 2 to 4 As shown, in some embodiments, the water-blocking structure 300 extends from the inner wall of the outer drum 100 towards the opening area of ​​the air outlet 110. The water-blocking structure 300 can cover at least a portion of the opening area of ​​the air outlet 110 facing the inner drum 200, directly blocking water from entering the air duct. Simultaneously, the water-blocking structure 300 retains another uncovered opening area for the air outlet 110, serving as the main channel for hot air circulation. This area is located downstream of the main water flow path, meaning that most of the water flow is intercepted upstream, resulting in almost no risk of water intrusion. Hot air can efficiently enter the outer drum 100 through this opening area, forming a functional zone. This design avoids the obstruction of hot air circulation caused by the water-blocking structure 300 completely covering the opening area of ​​the air outlet 110, and also solves the problem of water-blocking failure caused by the water-blocking structure 300 not covering or only covering a narrow area. It is suitable for the small space and multi-functional structural requirements of desktop washing machines and can also be adapted to various other types of clothing handling devices.

[0041] In some other embodiments, the water-blocking structure 300 may not cover the opening area of ​​the air outlet 110 facing the inner cylinder 200. Relying on the water flow direction guided by the structure of the water-blocking structure 300 itself, the water flow rushing towards the air outlet 110 can also be guided to the outside of the opening area of ​​the air outlet 110. This application does not limit this.

[0042] In some embodiments, the inner cylinder 200 rotates relative to the outer cylinder 100 about its central axis. The rotation direction of the inner cylinder 200 is the same as the extension direction of the water-blocking structure 300 from the inner wall of the outer cylinder 100 to the opening area of ​​the air outlet 110. This ensures that during the rotation of the inner cylinder 200, the guiding direction of the guide surface 310 does not conflict with the water flow direction, preventing excessive turbulence of the water flow. When the water flow is upstream, it is first guided by the water-blocking structure 300 and then slightly passes the air outlet 110 downstream. This ensures that the lowest point of the air outlet 110 is not located upstream of the water flow, allowing the water-blocking structure 300 to guide the water flow towards the air outlet 110 outside the opening area of ​​the air outlet 110. If the rotation direction of the inner cylinder 200 is opposite to the extension direction of the water-blocking structure 300 from the inner wall of the outer cylinder 100 to the opening area of ​​the air outlet 110, the end of the guide surface 310 will be downstream of the water flow relative to the air outlet 110. The water flow will instead surge into the air outlet 110 along the side of the guide structure 300 away from the guide surface 310. Moreover, the collision between the water flow and the guide surface 310 and the side wall of the air outlet 110 will cause the water flow to surge.

[0043] In some embodiments, along the rotation direction of the inner cylinder 200, the water-blocking structure 300 is located upstream of the air outlet 110. Further, the water-blocking structure 300 may be located between the highest point of the inner wall of the outer cylinder 100 and the intersection of the air outlet 110 and the inner wall of the outer cylinder 100. In the rotation direction of the inner cylinder 200, the water flow follows the rotation trajectory of the inner cylinder 200, sequentially having upstream and downstream directions. Upstream, the water flow is guided by the water-blocking structure 300 before flowing downstream past the air outlet 110. When the water flow reaches the area of ​​the water-blocking structure 300 along with the water ring, the water-blocking structure 300 exerts a lateral thrust on the water flow upstream of the air outlet 110, breaking the integrity of the water ring. The water ring is divided at the water-blocking rib into a water ring in the non-air outlet 110 area and a local water flow in the air outlet 110 area, preventing the entire water ring from accumulating towards the air outlet 110. After blocking the water flow, the water-blocking component guides the water flow to a different direction. The water-blocking structure 300 changes the direction of local water flow in the air outlet 110 area from the tangential direction along the inner wall of the outer cylinder 100 (towards the side wall of the air outlet 110) to the inward direction of the outer cylinder 100 (towards the outer wall of the inner cylinder 200), making the water flow direction lower than the lowest point of the air outlet 110. The redirected water flow can no longer contact the side wall of the air outlet 110, preventing backflow and water ingress at the source, thus ensuring the air quality of the air outlet 110. At the same time, it avoids water accumulation in the air outlet 110 during long-term use, which can cause continuous odor and ensure the user experience.

[0044] In some embodiments, along the axial direction of the outer cylinder 100, the width of the water-blocking structure 300 is not less than the width of the outer periphery of the air outlet 110. With this configuration, the water-blocking structure 300 can completely cover the opening range of the air outlet 110 in the axial direction, and water flow will be directly intercepted upon contact with the water-blocking structure 300, achieving effective shielding.

[0045] Furthermore, since the air outlet 110 is located on the side wall of the outer cylinder 100, it will weaken the structural strength of the outer cylinder 100 to a certain extent. For example, along the axial direction of the outer cylinder 100, the water-blocking structure 300 is set at the intersection of the air outlet 110 and the outer cylinder 100, and its width is not less than the width of the outer periphery of the air outlet 110. This is equivalent to adding a structure similar to a reinforcing rib to the edge of the air outlet 110. The water-blocking structure 300 is attached and fixed to the wall of the outer cylinder 100, which disperses the stress concentration at the edge of the air outlet 110 and prevents the outer cylinder 100 from cracking at the edge of the air outlet 110 due to long-term vibration.

[0046] The water-blocking structure 300 can be an integral structure formed with the outer cylinder 100 through casting, welding, or other methods. This reduces assembly processes, lowers manufacturing costs, and eliminates vulnerable parts and cleaning-required piping, significantly reducing maintenance costs. Alternatively, the water-blocking structure 300 can be detachably connected to the outer cylinder 100 via snap-fit ​​or screw-fit connections for easy cleaning and replacement. Furthermore, the material of the water-blocking structure 300 can be the same as or different from that of the outer cylinder 100, such as stainless steel, engineering plastics, or enamel, which offer high hardness and effectively block water flow. This application does not impose any restrictions on this.

[0047] The water-blocking structure 300 is used to guide the water flow towards the air outlet 110 to outside the opening area of ​​the air outlet 110. The water-blocking structure 300 does not simply block the water flow, but guides the water flow through space from the path that may enter the air outlet 110, that is, the opening area of ​​the air outlet 110, to outside the opening area of ​​the air outlet 110.

[0048] In some embodiments, the water-blocking structure 300 is plate-shaped and has a guide surface 310. The guide surface 310 is connected to the inner wall of the outer cylinder 100 and faces the inner cylinder 200, which can guide the water flow towards the air outlet 110 and prevent the water flow from hitting the side wall of the air outlet 110 or flowing into the air outlet 110.

[0049] In some embodiments, the guide surface 310 is planar and slopes from the inner wall of the outer cylinder 100 toward the inner cylinder 200. When the air outlet 110 is located at the upper part of the outer cylinder 100, one end of the guide surface 310 connected to the inner wall of the outer cylinder 100 is positioned above, that is, upstream of the air outlet 110, while the other end of the guide surface 310, which slopes from the inner wall of the outer cylinder 100 toward the inner cylinder 200, is positioned below and extends downstream of the air outlet 110. The slope of the guide surface 310 reduces the obstruction of the opening area of ​​the air outlet 110, avoids affecting the flow efficiency of the drying hot air, and ensures the air outlet effect.

[0050] During dehydration in the inner cylinder 200, the water flow surges upward along the inner wall of the outer cylinder 100 under the action of centrifugal force, forming a wall-attached upward water flow. Due to the "centrifugal pump effect" of the small-diameter inner cylinder 200, the water flow has the kinetic energy to continuously approach the air outlet 110. At this time, the angle of the guide surface 310 towards the inner cylinder 200 forms a guiding angle. After the water flow contacts the inclined guide surface 310, it is guided by the guide surface 310, and the direction of movement changes from upward along the wall of the outer cylinder 100 to downward along the guide surface 310, realizing the transfer from rushing towards the opening area of ​​the air outlet 110 to leaving the opening area of ​​the air outlet 110. The design of the guide surface 310, which slopes from the inner wall of the outer cylinder 100 toward the inner cylinder 200, allows the water to fall directly between the outer wall of the inner cylinder 200 and the inner wall of the outer cylinder 100 when it reaches the end of the guide surface 310. It can be guided along the outer wall of the inner cylinder 200 to a low water level area, and finally flow to the bottom of the inner cylinder 200 and be discharged. Alternatively, it can flow down along the inner wall of the outer cylinder 100, avoiding the accumulation of water in the middle to form a local high water level and eliminating the risk of secondary surge.

[0051] The plate-like structure of the inclined guide surface 310 does not require changes to the overall molding process of the outer drum 100. For desktop washing machines of different sizes and other types of clothing processing equipment, only the length and inclination angle of the guide surface 310 need to be adjusted, without the need to redevelop the mold, thus reducing investment costs.

[0052] In the planar structural design of the guide surface 310, the plane containing the guide surface 310 is the guiding direction of the water flow after it leaves the guide surface 310. The plane containing the guide surface 310 is located between the plane passing through the end of the guide surface 310 and tangent to the outer wall of the inner cylinder 200, and the plane passing through the end of the guide surface 310 and the lowest point of the air outlet 110. The end of the guide surface 310 is the end that extends away from the inner wall of the outer cylinder 100 and towards the opening area of ​​the air outlet 110. This design ensures that the trajectory of the water flow after leaving the guide surface 310 is below the lowest point of the air outlet 110, and also prevents the water flow from impacting the outer wall of the inner cylinder 200 and splashing or flowing back into the air outlet 110. Even when the inner cylinder is dewatering at high speed (200), the water flow will move upward due to the increase in kinetic energy, but it will not touch the lowest point of the air outlet 110, ensuring that the water flow rushing towards the air outlet 110 can be directed outside the opening area of ​​the air outlet 110.

[0053] If the plane where the guide surface 310 is located is lower than the plane at the end of the guide surface 310 and tangent to the outer wall of the inner cylinder 200, the end of the guide surface 310 will be too close to the outer wall of the inner cylinder 200. After the water flows away from the guide surface 310, it will adhere to the outer wall of the inner cylinder 200 due to inertia. Under the influence of the rotation of the inner cylinder 200, it will move upward again, forming a splashing motion against the wall. It may bypass the water-blocking structure 300 and enter the air outlet 110.

[0054] If the plane containing the guide surface 310 is higher than the plane between the end of the guide surface 310 and the lowest point of the air outlet 110, since the water-blocking structure 300 is located upstream of the air outlet 110, the lowest point of the air outlet 110 is the location where water is most likely to intrude. This arrangement will cause the end of the guide surface 310 to exceed the lowest point of the air outlet 110 and face the inner wall of the air outlet 110. Water flowing away from the guide surface 310 can easily directly impact the inner wall of the air outlet 110 and enter the air outlet channel.

[0055] Therefore, the plane containing the guide surface 310 is located between the plane passing through the end of the guide surface 310 and tangent to the outer wall of the inner cylinder 200 and the plane passing through the end of the guide surface 310 and the lowest point of the air outlet 110.

[0056] Furthermore, such as Figure 2 and Figure 3 As shown, the plane of the guide surface 310 is tangent to the outer wall of the inner cylinder 200. The point where the plane of the guide surface 310 is tangent to the outer wall of the inner cylinder 200 is lower than the lowest point of the air outlet 110, so that the tangent point is set below the lowest point of the air outlet 110, making the water flow tangential to the wall of the inner cylinder 200. After being turned, the water flow flows along the outer wall of the inner cylinder 200, and is further dispersed by the rotational force of the inner cylinder 200. The water flow can not come into contact with the side wall of the air outlet 110 at all, eliminating surging and splashing from the source, thereby ensuring the air quality of the air outlet 110.

[0057] The compact internal space caused by the small-diameter cylindrical assembly 10 maintains a gap between the guide surface 310 and the outer wall of the inner cylinder 200. This avoids physical interference while providing a reasonable channel for water flow. If the gap is too large, the water flow may bypass the guide surface 310; if it is too small, vibration may cause contact. When the inner cylinder 200 rotates at high speed, it will generate strong vibrations. If the end of the guide surface 310 is too close to the outer wall of the inner cylinder 200, it may cause interference between the two, affecting the normal operation of the entire machine.

[0058] In another embodiment, in addition to the design of the guide surface 310 being inclined from the inner wall of the outer cylinder 100 toward the inner cylinder 200, the guide surface 310 can also be an arc-shaped surface curving toward the air outlet 110. The radius of curvature of the arc-shaped surface can be adapted to the curvature of the inner wall of the outer cylinder 100, achieving a smooth tangential connection between the arc-shaped surface and the inner wall of the outer cylinder 100. When the inner cylinder 200 is dehydrated, the water flows upward along the inner wall of the outer cylinder 100 and will flow toward the air outlet 110. The arc-shaped surface is curved toward the air outlet 110 as a whole, with the convex surface facing the air outlet 110 but not extending into the air outlet channel, and the concave surface facing the direction of the water flow, buffering the impact of the water flow and preventing the water flow from entering the opening area of ​​the air outlet 110.

[0059] The curved surface bends towards the air outlet 110, away from the rotation trajectory of the inner cylinder 200, and the outer wall of the inner cylinder 200 maintains a certain distance from the curved surface. The tangent plane at the end of the guide surface 310 is located between the plane passing through the end of the guide surface 310 and tangent to the outer wall of the inner cylinder 200, and the plane passing through the end of the guide surface 310 and the lowest point of the air outlet 110. Here, the tangent plane refers to a plane at a certain point on the curved surface that is tangent to all tangents of the curved surface at that point. In this case, the tangent plane at the concave end of the guide surface 310 is a plane extending along the bending direction of the end of the curved surface, that is, the guiding direction after the water flow leaves the guide surface 310. This arrangement ensures that the trajectory of the water flow after leaving the guide surface 310 is below the lowest point of the air outlet 110, and also prevents the water flow from impacting the outer wall of the inner cylinder 200 and splashing or flowing back into the air outlet 110.

[0060] In another structural form, the water-blocking surface is set in a stepped shape. By cutting the water ring in stages and guiding the flow in a stepped manner, the kinetic energy of the water flow is weakened from the source. The stepped shape of the water-blocking surface can actively cut the water ring and guide the water flow to turn towards the outer wall of the inner cylinder 200, so that the water flow height is stably lower than the lower edge of the air outlet 110. Even in high-speed dehydration scenarios, it can effectively block water and solve the problem of water flow failure.

[0061] Alternatively, multiple protrusions or ribs can be provided on the water-blocking surface to cut and separate the water flow when it surges towards the guide surface 310. This actively intervenes in the water flow pattern, overcoming the limitations of passive interception. The latter controls the trajectory of the incoming water flow through energy dissipation and directional guidance, and responds to complex working conditions through flexible water flow dispersion and guidance, adapting to various application scenarios.

[0062] In some embodiments, the guide surface 310 is smoothly connected to the inner wall of the outer cylinder 100, forming a smooth guide path, reducing friction and collision between the water flow and the guide surface 310, preventing the water flow from escaping the guidance of the guide surface 310 and forming a splashing water flow. After the water flow changes direction, the guide surface 310 ensures the stability of the water flow trajectory through wall-adhering constraint. The tilt angle of the guide surface 310, in conjunction with gravity, causes the water flow to form a wall-adhering flow on the guide surface 310. The guide surface 310 reduces the water flow resistance, causing the water flow to continuously slow down during surface flow, thus preventing it from forming an upward surging tendency again.

[0063] Please refer to Figures 3 to 5In some embodiments, the cylinder assembly 10 further includes a plurality of mounting holes 320, which are spaced apart from each other and disposed on the water-blocking structure 300, or at the connection between the water-blocking structure 300 and the inner wall of the outer cylinder 100. For example, the number of mounting holes 320 can be 3 to 6. At least some of the mounting holes 320 are provided with defoaming components; for example, the number of defoaming components can be 1 to 6, and can be further adjusted according to the area of ​​the water-blocking structure 300. The plurality of mounting holes 320 are spaced apart from each other to ensure that sufficient water-blocking area is maintained between adjacent mounting holes 320, avoiding weakening the water-blocking effect due to too many openings.

[0064] It is understood that multiple mounting holes 320 can also be opened at the connection between the water-blocking structure 300 and the inner wall of the outer cylinder 100 to eliminate foaming caused by structural changes at the connection. This application does not impose specific restrictions on the number, size and shape of the mounting holes 320 and the defoaming components set in the mounting holes 320.

[0065] The defoaming component is made of a flexible porous material, such as a defoaming sponge. Its shape matches the mounting hole 320. The diameter of the defoaming sponge can be slightly larger than the pore diameter. It is fixed in the hole by interference fit without additional connectors. The surface of the defoaming sponge is hydrophilic to enhance its ability to absorb foam. The height of the defoaming component is consistent with the thickness of the water-blocking structure 300 and does not protrude from the surface of the water-blocking structure 300 to avoid interference with the rotation of the inner cylinder 200 or affecting the water flow guidance.

[0066] The mounting holes 320 are spaced apart, and the defoaming components within each hole 320 possess a certain strength. For example, the density of the defoaming sponge increases after compression, allowing it to withstand the impact of water flow. The openings will not cause insufficient interception area of ​​the water-blocking structure 300. The defoaming sponge only serves as an auxiliary defoaming function and does not affect the core water-blocking effect. Foam flowing with the water flow will cover the surface of the water-blocking structure 300. Foam flowing towards the mounting holes 320 area will be absorbed by the porous structure of the defoaming components, allowing them to quickly accommodate the foam and preventing foam accumulation on the surface of the water-blocking structure 300.

[0067] When foam enters the pores of the defoaming sponge, the friction and compression of the pore walls cause the foam film to rupture. The hydrophilic surface of the defoaming sponge absorbs the moisture from the foam, further weakening the stability of the foam film and causing the foam to rapidly decompose into liquid water. The decomposed liquid water flows along the pores of the defoaming sponge to the inside of the mounting hole 320, and then flows into the main water flow through the guide surface 310 of the water-blocking structure 300, without accumulating in the mounting hole 320 or reforming into foam. The decomposed foam, now liquid water, is more easily intercepted by the water-blocking structure 300. This process not only eliminates the interference of foam on the water-blocking function but also prevents foam from entering the air outlet 110, ensuring that the air outlet channel of the drying component is dry and clean.
