[0001] This invention belongs to the field of garment processing technology, and particularly relates to an outer tube assembly and garment processing equipment. Background Technology

[0002] In water-cooled drying garment processing equipment, the drying system typically includes a condenser duct and a heating duct. The drying airflow exchanges heat with the condensate in the condenser duct, transforming from a humid and hot state to a dry and cold state. It then enters the heating duct via a fan to be reheated, and finally enters the outer drum to exchange heat with the clothes to achieve drying. However, the existing condenser duct structure design has significant shortcomings: the width of the guide ribs in the condenser duct is uniform, failing to adapt to the airflow and condensate flow rates in different condensation zones; this results in insufficient heat exchange in the upper section of the condenser duct, and condensate is easily carried into the heating duct by the airflow; while the lower section of the condenser duct has high airflow resistance, reducing drying efficiency and energy efficiency.

[0024] In existing garment processing equipment that uses water-cooled drying, there are significant deficiencies in the design of the condenser duct structure: the width of the guide ribs inside the condenser duct is uniform, which cannot adapt to the airflow and condensate flow rate in different condensation zones; this results in insufficient heat exchange in the upper section of the condenser duct and condensate being easily carried into the heating duct by the airflow; while the airflow resistance in the lower section of the condenser duct is high, reducing drying efficiency and energy efficiency. This invention creatively provides an outer cylinder assembly for a garment processing device; the outer cylinder assembly includes an outer cylinder and a condensing air duct, the outer cylinder wall has a drying air outlet, the condensing air duct is located on the rear side of the outer cylinder and includes an air duct inlet communicating with the drying air outlet; the condensing air duct extends vertically, and the interior of the condensing air duct has an upper condensing zone and a lower condensing zone arranged vertically opposite each other; a plurality of first guide ribs are arranged sequentially at intervals along the extension direction of the condensing air duct; the width of the first guide rib located in the upper condensing zone is greater than the width of the first guide rib located in the lower condensing zone; The wide ribs in the upper condensation zone enhance the guiding and turbulence effects, promote the adhesion and spreading of condensate, prolong the heat exchange time between the drying airflow and the condensate, and improve the dehumidification effect; the narrow ribs in the lower condensation zone avoid unnecessary flow resistance, ensure the stability of the drying airflow, and guide the condensate to drain smoothly, effectively preventing it from being carried into the subsequent air duct by the airflow.

[0025] <Outer tube assembly> like Figures 1 to 2b As shown, this embodiment provides an outer drum assembly for garment processing equipment, particularly for drum-type washer-dryers; the outer drum assembly includes: The outer cylinder 2 has a drying air outlet formed on its cylinder wall; specifically, the axial direction of the outer cylinder 2 is horizontal; the cylinder wall of the outer cylinder 2 includes a cylinder peripheral wall 21 and a cylinder rear wall 22, the front end of the cylinder peripheral wall 21 has a cylinder opening, and the cylinder opening is provided with a drying air inlet; the rear end of the cylinder rear wall 22 is provided with a cylinder rear wall 22, and the cylinder rear wall 22 has a drying air outlet formed on it. A condensing air duct 11 is located at the rear of the outer cylinder 2 and includes an air inlet, an air outlet, and a water inlet. The air inlet is used to supply drying airflow into the condensing air duct 11, the air outlet is used to discharge the drying airflow from the condensing air duct 11, and the water inlet 114 is used to supply condensate into the condensing air duct 11. The air inlet and the drying air outlet are connected. The condensing air duct 11 extends vertically, and along its extension direction, it has multiple... Each of the condensing zones is provided with at least one first guide rib 12; the width of the first guide rib 12 is different for different condensing zones, and / or the distance between the end of the first guide rib and the inner wall of the condensing air duct 11 is different for different condensing zones; condensate enters the condensing air duct 11 through the water inlet 114, and the drying airflow enters the condensing air duct 11 through the air duct inlet and is discharged through the air duct outlet; the drying airflow and condensate exchange heat in the condensing air duct 11 to dehumidify the drying airflow; The drying airflow inside the outer cylinder 2 can enter the condensing air duct 11 through the drying air outlet and the air duct inlet, and exchange heat with the condensed water flowing through the condensing air duct 11; the width direction of the first guide rib 12 is parallel to the cross-sectional width direction of the condensing air duct 11, and the inner wall of the condensing air duct 11 is the inner wall of the condensing air duct 11 that is opposite to the extension direction of the first guide rib 12. Figure 2a In the diagram, 121 represents the width direction of the first guide rib, 122 represents the length direction of the first guide rib, the width direction of the first guide rib 12 is perpendicular to the length direction of the first guide rib, and the width direction of the first guide rib 12 is parallel to the cross-sectional width direction of the condensing air duct 11 and also parallel to the axial direction of the outer cylinder 2. By setting a first guide rib 12 inside the condensing air duct 11, and designing the width of the first guide rib 12 to be different according to the different condensing zones of the condensing air duct 11, the effective heat exchange area of ​​the upper condensing zone is increased, and the contact and heat exchange time between the drying airflow and the condensate is extended, thereby achieving precise and efficient dehumidification and enhancing the condensation effect; the wide ribs in the upper condensing zone enhance the guiding and turbulence effects, promoting the adhesion and spreading of condensate; the narrow ribs in the lower condensing zone avoid unnecessary flow resistance, ensure the stability of the drying airflow, and guide the condensate to drain smoothly.

[0026] Furthermore, the condensation zone includes an upper condensation zone and a lower condensation zone arranged opposite each other; the width of the first guide rib 12 located in the upper condensation zone is greater than the width of the first guide rib 12 located in the lower condensation zone; The upper condensing zone and the lower condensing zone are separated by the horizontal plane where the axis of the outer cylinder is located; the area above the interface in the condensing air duct 11 is the upper condensing zone, and the area below the interface in the condensing air duct 11 is the lower condensing zone.

[0027] Preferably, when the upper condensing zone and / or the lower condensing zone are provided with multiple first guide ribs 12, the multiple first guide ribs 12 are arranged sequentially at intervals along the extension direction of the condensing air duct 11.

[0028] The following describes the setting method and size of the first guide rib 12. Two adjacent first guide ribs 12 have different extension directions. The width of the cross-section of the condensing air duct 11 is a, and the width of the first guide rib 12 located in the upper condensing zone is b. a and b satisfy: 5mm≤b≤0.5*a. In this way, the condensate in the upper condensing zone can effectively adhere to and flow along the first guide rib 12, while avoiding the obstruction of the drying airflow due to the excessive width of the first guide rib 12, thereby achieving the technical effect of improving condensation efficiency and stability.

[0029] The width of the first guide rib 12 located in the lower condensation zone is c, where c satisfies: 2.5mm≤c≤5mm. This allows the condensate in the lower condensation zone to flow effectively. The first guide rib 12 receives and disperses the condensate blown away by the drying airflow, preventing the flow path of the drying airflow from being affected by the excessive width of the first guide rib 12, thereby improving the condensation effect and stability of the equipment.

[0030] The following describes the structure of the water-blocking rib at the upper air inlet 111 of the air duct. The air inlet of the air duct includes the upper air inlet 111 and the lower air inlet 112, which are arranged opposite each other. The outer cylinder assembly also includes a first water-blocking rib 13, which is disposed inside the condensation air duct 11 and surrounds the outside of the air inlet 111 on the air duct. The first water-blocking rib 13 is a semi-enclosed structure with an open opening on one side, facing upwards. The first water-blocking rib 13 can prevent condensate from entering the fan 31, heating duct 32, or air inlet 111 on the duct, thereby improving the stability of equipment operation.

[0031] The dimensions of the water-blocking ribs at the air inlet 111 of the air duct are explained below. The width of the first water-blocking rib 13 is d, which satisfies: 2.5mm≤d≤4mm. This ensures the orderly flow of condensate and the smooth passage of the drying airflow, effectively preventing the drying airflow from carrying the condensate out to the heating air duct 32 after entering the condensate air duct 11, thereby further improving the stability and safety of the equipment operation. The width of the first water-blocking rib 13 is the width of the first water-blocking rib 13 in the axial direction of the outer cylinder 2.

[0032] Furthermore, a first guide surface is formed on the side of the first water-blocking rib 13 near the air inlet 111 of the air duct. The first guide surface is inclined relative to the vertical direction to guide the condensate water to the area below the air inlet 111 of the air duct. Thus, during the drying process of the garment processing equipment, the condensate in the condensation duct 11 may splash or accumulate due to airflow or gravity, especially in the area near the air inlet 111 of the duct. By setting an inclined first guide surface, the condensate can be actively guided to the area below the air inlet 111 of the duct, preventing the condensate from directly entering the air inlet 111 of the duct.

[0033] In some embodiments, the air inlet 111 on the air duct is circular; there are three designs depending on the structure and position of the first water-blocking rib 13. Option 1: The first water-blocking rib 13 is extendable and retractable in the axial and circumferential directions at the air inlet 111 of the air duct. This allows adjustment of the axial and circumferential extension length of the first water-blocking rib 13 at the air inlet 111 according to the flow rate and humidity of the drying airflow within the condensing air duct 11. Specifically, the first water-blocking rib 13 is made of a flexible material and has a first inner cavity. Fluid can be filled into the first inner cavity. After the fluid is filled, the first water-blocking rib 13 undergoes axial and circumferential deformation at the air inlet 111 of the air duct, thus changing its extension length. This can be adjusted... The flow rate of the fluid filling the first inner cavity can be adjusted by regulating the axial and circumferential extension length of the first water-blocking rib 13 at the air inlet 111 on the air duct; the first inner cavity has a first inner cavity inlet, and a first pump body is provided outside the condensing air duct 11. The outlet of the first pump body is connected to the first inner cavity inlet, and the first pump body can deliver fluid into the first inner cavity; the first inner cavity also has a first inner cavity outlet, and a first water outlet pipe is connected to the outside of the first inner cavity outlet. The first water outlet pipe is connected to a first water outlet solenoid valve; by controlling the opening of the first water outlet solenoid valve, the fluid in the first inner cavity can be discharged through the first inner cavity outlet; Thus, Option 1 can achieve the following technical effects: ① The core effect of this solution is to transform the first water-blocking rib 13 from a fixed structure into an intelligent adjustable structure. When the humidity of the drying airflow is high and there is a lot of condensate, the extension length of the first water-blocking rib 13 can be increased to form a larger protective area and more effectively prevent water from splashing into the air duct. When the airflow velocity is high and the wind pressure is high, the first water-blocking rib 13 can be appropriately contracted to reduce its resistance to the airflow, ensure the ventilation efficiency of the drying system, and avoid increased energy consumption. This solves the technical problem in the existing technology that fixed water-blocking ribs cannot simultaneously meet the contradiction between "high-efficiency water blocking" and "low wind resistance" under different working conditions. ② The drying load (amount of clothes) and the selected program (drying intensity) of the clothing processing equipment will cause dynamic changes in the flow field and humidity environment in the condenser duct 11. This solution enables the outer cylinder assembly to adapt to various working conditions through real-time adjustment, and always maintain a near-optimal working state, thereby improving the working efficiency, energy efficiency level and operational reliability of the entire equipment.

[0034] Option 2: The first water-blocking rib 13 is rotatably mounted at the air inlet 111 of the air duct, and the rotation axis of the first water-blocking rib 13 is collinear with the axis of the air inlet 111 of the air duct; the position of the opening of the first water-blocking rib 13 can be adjusted according to the flow rate and humidity of the drying airflow in the condensing air duct 11; specifically, the first water-blocking rib 13 and the inner wall of the condensing air duct 11 are slidably fitted, the first water-blocking rib 13 is provided with a first magnetic component, and the outer wall of the condensing air duct 11 is provided with a rotatable second magnetic component, the first magnetic component and the second magnetic component are connected by magnetic force; the rotation axis of the second magnetic component is collinear with the rotation axis of the first water-blocking rib 13, and the second magnetic component is driven by a drive motor; when the drive motor rotates, the second magnetic component drives the first magnetic component and the first water-blocking rib 13 to rotate; Thus, Option 2 can achieve the following technical effects: ① This solution changes the orientation of the opening by rotating the water-blocking ribs, so that the system can intelligently adjust the opening to the position where the flow needs to be guided according to the actual distribution and flow pattern of condensate on the inner wall of the air duct, thereby achieving more precise and effective guidance and discharge of condensate.

[0035] The following describes the structure of the water baffle at the drying air outlet. The drying air outlet includes an upper drying air outlet 221 and a lower drying air outlet 222 arranged opposite to each other. The upper drying air outlet 221 is correspondingly arranged and connected to the upper air inlet 111 of the air duct. The lower drying air outlet 222 is correspondingly arranged and connected to the lower air inlet 112 of the air duct. The outer cylinder assembly also includes a second water-blocking rib 241 and a third water-blocking rib 242. The second water-blocking rib 241 and the third water-blocking rib 242 are both arranged inside the outer cylinder 2. The second water-blocking rib 241 surrounds the outside of the upper air outlet 221 of the dryer, and the third water-blocking rib 242 surrounds the outside of the lower air outlet 222 of the dryer. The second water-blocking rib 241 and the third water-blocking rib 242 are both semi-enclosed structures with an opening on one side. The opening of the second water-blocking rib 241 faces upward, and the opening of the third water-blocking rib 242 faces downward. The inner surface of the rear wall 22 of the cylinder serves as a condensation surface, through which drying airflow and condensate flow. The condensation surface is provided with a second guide rib 23 to guide the condensate flow through the condensation surface, increasing the contact area and contact time between the condensate and the drying airflow, thereby improving the condensation efficiency. A portion of the drying airflow inside the outer cylinder 2 enters the condensation duct 11 through the lower drying outlet 222 and the lower air inlet 112 of the duct, and exchanges heat with the condensate flowing through the condensation duct 11. Another portion of the drying airflow inside the outer cylinder 2 first flows through the condensation surface, and then enters the condensation duct 11 through the upper drying outlet 221 and the upper air inlet 111 of the duct. It exchanges heat with the condensate flowing through the condensation surface. The drying airflow in the condensation duct 11 is discharged through the duct outlet 113. The second baffle 241 prevents condensate flowing over the condensing surface from entering the condensing duct 11 through the upper air outlet 221 of the dryer, and the third baffle 242 prevents condensate flowing over the condensing surface from entering the condensing duct 11 through the lower air outlet 222 of the dryer; thereby preventing condensate from entering the downstream fan 31 and heating duct 32 through the air outlet 113 of the duct, thus improving the stability and safety of equipment operation.

[0036] The dimensions of the water-blocking ribs at the drying air outlet are explained below. The width of the second water-blocking rib 241 is e, and the width of the third water-blocking rib 242 is f. e and f satisfy: 2.5mm≤e≤4mm, 2.5mm≤f≤4mm. The width of the second water-blocking rib 241 is the width of the second water-blocking rib 241 in the axial direction of the outer cylinder 2, and the width of the third water-blocking rib 242 is the width of the third water-blocking rib 242 in the axial direction of the outer cylinder 2.

[0037] In some embodiments, the upper air outlet 221 and the lower air outlet 222 of the dryer are circular; there are two designs based on the different structures and positions of the second water-blocking rib 241 and the third water-blocking rib 242. Option 1: Both the second water-blocking rib 241 and the third water-blocking rib 242 are semi-circular. The radius of the second water-blocking rib 241 is larger than the radius of the upper air outlet 221 of the dryer, and the radius of the third water-blocking rib 242 is larger than the radius of the lower air outlet 222 of the dryer. Preferably, the second water-blocking rib 241 and the upper air outlet 221 of the dryer are coaxially arranged, and the third water-blocking rib 242 and the lower air outlet 222 of the dryer are coaxially arranged. The second baffle 241 is extendable and retractable in the axial and circumferential directions at the upper air outlet 221 of the drying chamber, and its extension and retraction length in the axial and circumferential directions can be adjusted according to the flow rate and humidity of the drying airflow inside the outer cylinder 2; the third baffle 242 is extendable and retractable in the axial and circumferential directions at the lower air outlet 222 of the drying chamber, and its extension and retraction length in the axial and circumferential directions can be adjusted according to the flow rate and humidity of the drying airflow inside the outer cylinder 2. Specifically, the second water-blocking rib 241 is made of flexible material, and a second inner cavity is formed inside the second water-blocking rib 241. Fluid can be filled into the second inner cavity. After the fluid is filled into the second inner cavity, the second water-blocking rib 241 undergoes axial and circumferential deformation at the air outlet 221 of the drying machine, thereby changing the length of the expansion and contraction. By adjusting the flow rate of the fluid filled into the second inner cavity, the axial and circumferential length of the second water-blocking rib 241 at the air outlet 221 of the drying machine can be adjusted. A second inner cavity inlet is formed in the second inner cavity. A second pump body is provided outside the outer cylinder 2. The outlet of the second pump body is connected to the second inner cavity inlet, and the second pump body can deliver fluid into the second inner cavity. A second inner cavity outlet is also formed in the second inner cavity. A second water outlet pipe is connected to the second inner cavity outlet, and the second water outlet pipe is connected to a second water outlet solenoid valve. By controlling the opening of the second water outlet solenoid valve, the fluid in the second inner cavity can be discharged through the second inner cavity outlet. The third water-blocking rib 242 is made of flexible material and has a third inner cavity. Fluid can be filled into the third inner cavity. After the fluid is filled, the third water-blocking rib 242 undergoes axial and circumferential deformation at the air outlet 222 during drying, thus changing its length. By adjusting the flow rate of the fluid in the third inner cavity, the axial and circumferential length of the air outlet 222 during drying can be adjusted. The third inner cavity has a third inner cavity inlet, and a third pump body is provided outside the outer cylinder 2. The outlet of the third pump body is connected to the inlet of the third inner cavity, allowing the pump body to deliver fluid into the third inner cavity. The third inner cavity also has a third inner cavity outlet, which is connected to a third water outlet pipe, which is connected to a third water outlet solenoid valve. By controlling the opening of the third water outlet solenoid valve, the fluid in the third inner cavity can be discharged through the third inner cavity outlet. Thus, Option 1 can achieve the following technical effects: ① By making the second water-blocking rib 241 and the third water-blocking rib 242 retractable, the system can dynamically adjust the protection range of the second water-blocking rib 241 and the third water-blocking rib 242 according to the real-time monitored airflow velocity (reflecting wind pressure and drying intensity) and humidity (reflecting the dryness and humidity of clothes and condensation load) inside the drum; the water-blocking range is increased in the high humidity and splash-prone stage, and the wind resistance is reduced in the high-speed airflow stage, thereby achieving precise management of moisture in the drying airflow at the source, ensuring that efficient and reliable drying and waterproofing effects are maintained under various clothing loads and drying programs; ② The adjustment is made directly at the air outlet of the outer cylinder 2, which manages the drying airflow before it enters the condenser duct 11 from the "source". This effectively prevents the moisture inside the cylinder from being directly carried out by the high-speed airflow, which not only protects the air duct, but also reduces the heat exchange load of the subsequent condenser duct 11. Through adaptive adjustment, the best balance point is always found between "water blocking effect" and "ventilation efficiency", thereby optimizing the energy efficiency of the equipment while ensuring the drying effect.

[0038] Option 2: Multiple second water-blocking ribs 241 are provided, and the multiple second water-blocking ribs 241 are staggered in both the radial and circumferential directions at the upper air outlet 221 of the dryer; multiple third water-blocking ribs 242 are provided, and the multiple third water-blocking ribs 242 are staggered in both the radial and circumferential directions at the lower air outlet 222 of the dryer. Thus, Option 2 can achieve the following technical effects: ① This solution adopts a "multi-passive protection" strategy in the critical area inside the outer cylinder 2. By setting multiple second water-blocking ribs 241 that are radially and circumferentially staggered around the upper air outlet 221 and the lower air outlet 222 of the dryer, a three-dimensional, labyrinthine protection structure is formed. This can effectively cope with the complex and ever-changing splashing environment inside the outer cylinder 2. Even if water flows through the first barrier, it will be intercepted and guided by the subsequent staggered water-blocking ribs, which significantly reduces the possibility of water flowing directly into the drying air outlet, thus ensuring the dryness and safety of the system from the source. ② The water flow inside the outer cylinder 2 has the characteristics of gravity, centrifugal force and airflow entrainment, with disordered direction and strong impact force; a single second water-blocking rib 241 may have a blind spot, but multiple staggered second water-blocking ribs 241 form a protective net without blind spots. No matter which direction the water splashes from, there will always be one or more barriers that can block and guide the flow. It is especially suitable for dealing with the complex turbulence generated when the drum rotates and the direct water splash generated when clothes fall.

[0039] In addition, the first guide rib 12 and the second guide rib 23 are both made of metal or high-temperature resistant plastic, and their cross-sectional shape can be rectangular, trapezoidal or sawtooth. The specific shape can be optimized according to the manufacturing process and heat exchange efficiency. The first guide rib 12 is fixed to the inner wall of the condensing air duct 11 by welding or bonding to ensure structural stability and not affect the flow of drying air. The second guide rib 23 is fixed to the condensing surface by welding or bonding to ensure structural stability.

[0040] In addition, the outer cylinder assembly also includes a fourth water baffle 14, which is disposed in the condensation air duct 11. At least a portion of the fourth water baffle 14 is located between the water inlet 114 and the air outlet of the air duct; the fourth water baffle 14 is closer to the water inlet 114 than the air outlet of the air duct. Thus, the fourth baffle 14 prevents condensate entering the condensing duct 11 from the inlet 114 from splashing towards the duct outlet. It also directly and effectively blocks condensate from flowing with the drying airflow to the duct outlet, preventing it from entering the downstream fan and heating duct. This avoids fan malfunctions caused by condensate intrusion, effectively reducing the fan failure rate and extending the motor's lifespan. Simultaneously, it ensures that the heating element's thermal efficiency is not lost due to condensate, allowing the heating element to heat the drying airflow to the preset temperature. Without increasing the volume of the condensing duct 11, the flow rate of the drying airflow can be increased, improving drying efficiency and shortening the drying time. In wrinkle removal and odor removal processes, the increased flow rate of the drying airflow allows the garments to unfold, improving the care effect.

[0041] Furthermore, the fourth water-blocking rib 14 includes a first water-blocking section 141 and a second water-blocking section 142 connected to the first water-blocking section 141; one end of the first water-blocking section 141 is arranged around the water inlet 114, and the other end extends downwards from the water inlet 114; the second water-blocking section 142 is below the first water-blocking section 141 and the second water-blocking section 142 has a continuously bent shape; the second water-blocking section 142 and the inner wall of the condensation air duct 11 form a water-passing space 15; The first guide rib 12 located in the upper condensation zone is set in the water passage space 15; The width of the fourth water-blocking rib 14 is the same as the width of the first guide rib 12, or the width of the fourth water-blocking rib 14 is slightly larger than the width of the first guide rib 12 (greater than about 1 mm). In this way, the following technical effects can be achieved: ① First water-blocking section 141: Because it is "located downstream of the inlet 114", it is the first to receive the condensate flow from the inlet 114; its vertically extending structure can efficiently "split" or "tear" a concentrated flow of water, thus initially dispersing it. Second water-blocking section 142: receives the water flow initially dispersed from the first water-blocking section 141, and further spreads and redistributes the water flow laterally through its extension structure; This two-stage mechanism of "first breaking down longitudinally, then spreading laterally" can distribute condensate more quickly and evenly across a wider air duct cross-section; it greatly increases the contact area and mixing uniformity between condensate and rising drying airflow, thereby significantly improving heat and mass exchange efficiency at the microscopic level. ② This greatly increases the complexity of the path by which water droplets are carried by the airflow and fly directly to the air outlet; As the airflow bypasses this complex barrier, the flow field undergoes more complex changes, generating more vortices. This helps to slow down the entrained water droplets and cause them to collide and coalesce with the barrier surface or other water droplets, eventually falling due to gravity. This multi-dimensional complex barrier structure provides a more reliable "water-locking" guarantee than the single-direction fourth water-blocking rib 14. It upgrades the simple barrier to a "labyrinth-like" sealing principle, significantly reducing the risk of "water drift" and improving the stability and reliability of the garment processing equipment during long-term operation.

[0042] The following describes the positional relationship between the first water-blocking section 141 and the water inlet 114. The condensing assembly includes a condensing shell 115 and a condensing cover 116 arranged opposite to each other. The condensing cover 116 is fastened to the condensing shell 115 and together with the condensing shell 115, they form a condensing air duct 11. The condensing shell 115 has an air duct inlet and an air duct outlet. Specifically, the condensing shell 115 and the condensing cover 116 are sealed together to prevent air and water leakage. The condensing shell 115 is provided with a portion of the first guide ribs 12, and the condensing cover 116 is provided with another portion of the first guide ribs 12. The fourth water-blocking rib 14 is provided on the condenser cover 116; in the left and right direction, the left wall of the condenser cover 116 forms a water inlet 114, the first water-blocking section 141 is located to the right of the water inlet 114, and a flow guide channel is formed between the first water-blocking section 141 and the left wall of the condenser cover 116, the flow guide channel is connected to the water passage space; the flow guide channel enables the water inlet 114 to flow from top to bottom and then enter the water passage space.

[0043] In this way, the following technical effects can be achieved: ① The guide channel constrains the condensate flowing in from the inlet 114 from a disordered state that may splash everywhere into a regular water flow or water film that is confined within the channel and flows "from top to bottom" close to the inner wall of the condensate cover 116; This "flow guiding" design solves the initial distribution problem of condensate when it enters the condensation duct 11, ensuring that the condensate is not instantly blown away or randomly dripped by the high-speed airflow, but is forcibly and orderly guided to the predetermined key area in the duct (i.e., the space between the first water-blocking section 141 and the inner wall of the condensation duct 11); it provides ideal preconditions for the subsequent "breaking" and "spreading" of the condensate by the first water-blocking section 141 and the second water-blocking section 142, thus optimizing the entire condensation process from the source; ② The water film or water flow that forms a downward flow along the wall through the guide channel is effectively pulled apart laterally when it encounters the second water-blocking section 142 below, thereby forming a more extensive and dynamic "water curtain" in the condensation air duct 11; this "water curtain" directly lies across the path of the drying airflow rising from below, greatly increasing the air-water contact area. At the same time, the kinetic energy of this guided water flow has been effectively consumed and utilized by the guide channel and subsequent water blocking section, greatly reducing the possibility of generating fine water droplets due to direct impact and splashing and being carried away by the airflow. The combination of "flow guide channel + fourth water-blocking rib 14" constitutes a complete and efficient water flow management system; it is not just a passive "water blocking", but an active "flow guide" and "water distribution" to ultimately form a "water curtain"; it converts the potential energy and kinetic energy of the water flow into a form that is conducive to condensation and prevents escape, achieving functional synergy and bringing significant progress.

[0044] Figure 4 To simulate the flow path of condensate through the condensate duct when the first guide rib and the fourth water-blocking rib are installed, from... Figure 4 As can be seen, the condensate enters the condenser duct through the inlet, and then enters the water passage through the guide channel. Under the action of the first guide rib, the condensate flows along the first guide rib, realizing full contact between the drying airflow and the condensate, thereby improving the heat exchange efficiency and dehumidification effect.

[0045] <Clothing Processing Equipment> like Figure 3 As shown, this embodiment also provides a clothing processing device, including a heating air duct 32, a fan 31, an inner cylinder, and an outer cylinder assembly as described in any of the above; the front side of the outer cylinder 2 is provided with a cylinder opening, and a drying air inlet is provided at the cylinder opening; the condensing air duct 11 is provided on the rear side of the outer cylinder 2; the inner cylinder is rotatably disposed inside the outer cylinder 2, and the inner cylinder is used to carry clothing; The drying air outlet, condensing air duct 11, fan 31, heating air duct 32, drying air inlet, inner cylinder, and outer cylinder 2 are sequentially connected to form a drying airflow circuit. When the fan 31 is running, the drying airflow can circulate in the drying airflow circuit. The drying airflow flows from bottom to top through the condensing air duct 11, and the condensate flows from top to bottom. The condensate and the drying airflow come into contact and exchange heat. The condensate enters the outer cylinder 2 through the lower air inlet 112 of the air duct and is discharged through the outer cylinder 2. When the drying airflow passes through the heating air duct 32, the temperature of the drying airflow increases under the action of the heating element inside the heating air duct 32. When the drying airflow passes through the outer cylinder 2, it exchanges heat with the clothes inside the inner cylinder, thereby drying the clothes.
