Detailed Implementation

[0050] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0051] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] The garment handling tube assembly according to an embodiment of this application is described below with reference to Figures 1-13.

[0053] The garment handling tube assembly according to embodiments of this application may include: an outer tube 200, an inner tube 300, and a water-blocking component 100.

[0054] The pipe connector 201 is located on the outer peripheral wall of the outer cylinder 200. The pipe connector 201 defines a first airflow channel 2011 that communicates with the inner cavity 203 of the outer cylinder. When the clothes are dried in the clothes processing chamber, the humid air in the clothes processing chamber enters the air duct assembly 400 through the first airflow channel 2011 defined by the pipe connector 201, or the dry air in the air duct assembly 400 enters the clothes processing chamber through the first airflow channel 2011 defined by the pipe connector 201.

[0055] Since the first airflow channel 2011 defined by the pipe connector 201 is connected to the garment processing chamber, when the garment is dehydrated in the garment processing chamber, the water in the garment processing chamber will splash onto the outer cylinder 200 wall under the action of centrifugal force, and enter the air duct assembly 400 through the first airflow channel 2011, causing water to accumulate in the air duct assembly 400 and affecting the drying performance of the air duct assembly 400.

[0056] Therefore, this application embodiment designs a clothing processing tube assembly with a water-blocking member 100 in the first airflow channel 2011. Thus, the water-blocking member 100 can change the direction of water splashing, so that the water flow bounces back downward under the obstruction of the water-blocking member 100, and prevents the water flow from splashing into the air duct assembly 400.

[0057] Furthermore, to prevent the water-blocking component 100 from affecting the normal passage of airflow within the first airflow channel 2011, the water-blocking component 100 and the pipe connector 201, and / or the water-blocking component 100 itself, define an outlet to allow airflow to pass through the first airflow channel 2011. Thus, the water-blocking component 100 can change the splashing direction of the water flow in the dehydration mode of the clothing processing device without affecting the entry of humid air into the air duct assembly 400 through the first airflow channel 2011 defined by the pipe connector 201, or the entry of dry air in the air duct assembly 400 into the clothing processing chamber through the first airflow channel 2011 defined by the pipe connector 201. This causes the water flow entering the pipe connector 201 to bounce back downwards under the obstruction of the water-blocking component 100, preventing water from splashing into the air duct assembly 400 and affecting the drying performance of the air duct assembly 400.

[0058] According to the embodiments of this application, the garment processing drum assembly is provided with a water baffle 100 that can change the direction of water splashing without affecting the ventilation in the airflow channel, thereby preventing water accumulation in the air duct assembly 400 and ensuring the drying performance of the air duct assembly 400.

[0059] The outer cylinder 200 can extend horizontally or be inclined relative to the horizontal direction. The inner cylinder 300 is rotatably disposed in the inner cavity 203 of the outer cylinder. The inner cavity of the inner cylinder 300 is used to accommodate clothes. The clothes define a clothes processing chamber in the inner cavity of the inner cylinder 300. The clothes are washed, dehydrated or dried in the clothes processing chamber. Referring to Figure 3, the inner peripheral wall of the outer cylinder 200 and the channel wall 20111 of the first airflow channel 2011 have an intersection line S. After the water flows through the intersection line S, it no longer contacts the inner peripheral wall of the outer cylinder. The water continues to flow under the action of inertia and gravity. Since the flow direction of the water at the intersection line S is the same as the direction of the tangent L of the outer cylinder 200 at the intersection line S, most of the water will flow through the space below the tangent L and pass through the first airflow channel 2011. In the cross section perpendicular to the axial direction of the outer cylinder 200, the water baffle 100 is located on the side of the tangent L of the inner peripheral wall of the outer cylinder 200 at the highest point of the intersection line S that is away from the inner cavity 203 of the outer cylinder, so as to avoid a large amount of water directly impacting the water baffle 100, affecting the setting stability of the water baffle 100, and affecting the water baffle effect of the water baffle 100.

[0060] As shown in Figure 2, the first axial end 2012 of the pipe connector 201 is close to the outer cylinder 200, and the second axial end 2013 is far away from the outer cylinder 200. In some embodiments, the first axial end 2012 of the pipe connector 201 is the lower end of the pipe connector 201, and the second axial end 2013 of the pipe connector 201 is the lower end of the pipe connector 201. The water baffle 100 includes a first baffle 1. The first baffle 1 gradually deviates from the inner cavity 203 of the outer cylinder from the second end 2013 to the first end 2012. When the water flow impacts the first baffle 1, the first baffle 1 will give the water flow a reaction force in the direction of the inner cavity 203 of the outer cylinder. The reaction force drives the water flow to change direction, and the water flow will flow into the outer cylinder 200, thereby preventing the water flow from splashing into the air duct assembly 400 through the first airflow channel 2011.

[0061] Referring to Figure 3, the axial angle α between the first baffle 1 and the pipe connector 201 is greater than 20° and less than 45°. On the one hand, this avoids the water flow from splashing upwards and into the air duct assembly 400 if the axial angle α between the first baffle 1 and the pipe connector 201 is too small. On the other hand, it avoids the first baffle 1's projected area on the plane perpendicular to the airflow direction being too large, which would affect the normal passage of airflow in the first airflow channel 2011 and ensure the airflow rate.

[0062] As shown in Figures 4 and 10-13, the channel wall 20111 of the first airflow channel 2011, corresponding to the side of the first baffle 1 facing the inner cavity 203 of the outer cylinder, faces away from the direction of water flow, making it less likely to come into contact with water and cause splashing. No additional water-blocking structure is needed between the side of the first baffle 1 facing the inner cavity 203 of the outer cylinder and the corresponding channel wall 20111 of the first airflow channel 2011; therefore, this space can be used for airflow. Specifically, the flow outlet includes a first flow outlet 101, which is defined between the side of the first baffle 1 facing the inner cavity 203 of the outer cylinder and the channel wall 20111 of the first airflow channel 2011 to ensure normal airflow within the first airflow channel 2011.

[0063] Referring to Figures 10 and 11, in some embodiments, the cross-section of the first airflow channel 2011 is formed as a circle. With a diameter line parallel to the axial direction of the outer cylinder 200 as the central axis, the channel wall 20111 of the first airflow channel 2011, corresponding to the semicircle on one side away from the inner cavity 203 of the outer cylinder, mainly receives the splashed water flow. The channel wall 20111 of the first airflow channel 2011, corresponding to the semicircle on the other side, faces away from the direction of the water flow and is not easy to come into contact with the water flow and cause splashing. By limiting the projection of the first baffle 1 on the plane perpendicular to the axial direction of the pipe joint 201 to at least cover the center of the first airflow channel 2011, it can be ensured that the protection range of the first baffle 1 covers the channel wall 20111 of the first airflow channel 2011, corresponding to the semicircle on one side away from the inner cavity 203 of the outer cylinder. This ensures that the water flow is first turned by the first baffle 1 before contacting the channel wall 20111 of the first airflow channel 2011, thus preventing the water flow from splashing into the inner cavity of the air duct assembly 400.

[0064] In some embodiments, the first baffle 1 is integrally formed with the pipe connector 201 to ensure that the first baffle 1 can be stably disposed in the garment handling tube assembly.

[0065] The first baffle 1 and the outer cylinder 200 can also be formed separately, and then connected and fixed by welding, bonding, screw connection or other methods.

[0066] Specifically, in conjunction with the embodiments shown in Figures 1-13, the first baffle 1 is provided with a first connecting part 11, and the outer cylinder 200 is provided with a second connecting part 202. The first connecting part 11 and the second connecting part 202 are connected to fix the first baffle 1 in the first airflow channel 2011.

[0067] In some embodiments, the first baffle 1 and the outer cylinder 200 are fixedly connected by fasteners. Specifically, referring to Figures 1-13, the first connecting part 11 includes a first connecting hole, the second connecting part 202 includes a connecting rib 2021 and the connecting rib 2021 is provided with a second connecting hole, and the first baffle 1 is fixed in the first airflow channel 2011 by fasteners and the fasteners pass through the first connecting hole and the second connecting hole.

[0068] The connecting rib 2021 is formed in the shape of a strip to ensure its own stability, thereby ensuring the stability of the first baffle 1. In addition, the projected area of ​​the connecting rib 2021 on the plane perpendicular to the airflow direction is small, so as to avoid the setting of the connecting rib 2021 from affecting the normal flow of airflow.

[0069] Referring to Figures 1-4, the water-blocking component 100 also includes a second baffle 2, which is located on the side of the first baffle 1 away from the inner cavity 203 of the outer cylinder.

[0070] As some water flows from below the first baffle 1 and splashes onto the channel wall 20111 of the first airflow channel 2011 facing the direction of the water flow, the channel wall 20111 of the first airflow channel 2011 will give a reaction force to the water splashed on it, causing the water to spread outwards, with some splashing upwards. This part of the water is easy to splash into the inner cavity of the air duct assembly 400.

[0071] Therefore, by setting the second baffle 2, water splash can be further blocked outside the air duct assembly 400, ensuring the energy efficiency of the air duct assembly 400.

[0072] As shown in Figure 2, the second end 2013 to the first end 2012 of the second baffle 2 extend towards the first baffle 1. Thus, the reaction force of the second baffle 2 on the water flow is directed downwards and toward the side opposite to the first baffle 1, which can further block the water flow from splashing outside the air duct assembly 400 and ensure the energy efficiency of the air duct assembly 400.

[0073] Referring to Figure 3, the angle β between the second baffle 2 and the plane perpendicular to the axial direction of the pipe connector 201 is greater than 5° and less than 45°. When the angle between the second baffle 2 and the plane perpendicular to the axial direction of the pipe connector 201 is too small, the projected area of ​​the second baffle 2 on the plane perpendicular to the airflow direction is larger, which affects the airflow passage. When the angle between the second baffle 2 and the plane perpendicular to the axial direction of the pipe connector 201 is too large, the second baffle 2 needs to be set long enough to cover the splash path of the water flow, resulting in high production costs.

[0074] Furthermore, there is a dead airflow area above the second baffle 2, and the lint on the second baffle 2 cannot move towards the air duct assembly 400 under the drive of airflow. The second baffle 2 needs to have a certain angle with the surface perpendicular to the axial direction of the pipe joint 201 so that the lint on the second baffle 2 can slide off the second baffle 2 under the action of gravity, and avoid the accumulation of lint above the second baffle 2, which will affect the user experience.

[0075] As shown in Figures 4 and 10-13, the flow outlet also includes a second flow outlet 102. The second flow outlet 102 is defined between the second baffle 2 and the first baffle 1. That is, the airflow can flow to the air duct assembly 400 or to the clothing processing chamber through the first flow outlet 101 defined between the first baffle 1 and the channel wall 20111 of the first airflow channel 2011 and the second flow outlet 102 defined between the second baffle 2 and the first baffle 1. The water-blocking component 100 reserves two flow outlets for airflow to ensure normal airflow.

[0076] Referring to Figures 7, 10, and 11, the projections of the second baffle 2 and the first baffle 1 on the plane perpendicular to the axial direction of the pipe joint 201 do not coincide, so that some airflow can flow more smoothly through the gap between the first baffle 1 and the second baffle 2, reducing the impact of the water-blocking component 100 on airflow.

[0077] Referring to Figures 1-4 and 9, the projections of the second baffle 2 and the first baffle 1 on the plane parallel to the axial direction of the pipe joint 201 do not coincide. In other words, the first baffle 1 and the second baffle 2 are not located on the same horizontal plane to avoid the first baffle 1 and the second baffle 2 blocking the same plane at the same time, causing excessive flow resistance at that point and causing the first airflow channel 2011 to be blocked.

[0078] By making the first baffle 1 and the second baffle 2 not located on the same horizontal plane, the flow resistance can be reduced, the area available for airflow can be increased, and the normal flow of airflow can be ensured.

[0079] According to some embodiments of this application, the second baffle 2 is integrally formed with the pipe joint 201 to achieve the fixation of the second baffle 2 within the pipe joint 201.

[0080] Alternatively, according to other embodiments of this application, in conjunction with the embodiments shown in Figures 1-13, the second baffle 2 is connected to the first baffle 1 to be fixed in the first airflow channel 2011 by the first baffle 1. Since the first baffle 1 is fixedly installed in the pipe joint 201, the second baffle 2, which is fixedly connected to the first baffle 1, can also be fixedly installed in the pipe joint 201, which simplifies the production difficulty of the outer cylinder 200 and reduces the production cost.

[0081] Specifically, as shown in Figures 6-8, the second baffle 2 and the first baffle 1 can be connected by a connecting plate 3. The water-blocking component 100 also includes a connecting plate 3, which is connected to the outer periphery of the second baffle 2, and the two ends of the connecting plate 3 are respectively connected to the two ends of the first baffle 1. The connecting plate 3, the first baffle 1, and the second baffle 2 are integrally formed. Thus, the entire water-blocking component 100 can be fixedly installed in the pipe joint 201 to achieve the fixation of the entire water-blocking component 100.

[0082] Furthermore, the connecting plate 3 can improve the strength of the first baffle 1 and the second baffle 2, ensure the stability of the first baffle 1 and the second baffle 2, and prevent the first baffle 1 and the second baffle 2 from being damaged under external force.

[0083] Referring to the embodiments shown in Figures 10-13, the shape of the connecting plate 3 is adapted to the shape of the channel wall 20111 of the first airflow channel 2011. That is, the connecting plate 3 is set along the channel wall 20111 of the first airflow channel 2011. On the one hand, it can avoid the airflow from passing through the opening and prevent the setting of the connecting plate 3 from affecting the normal flow of airflow. On the other hand, through the cooperation between the connecting plate 3 and the channel wall 20111 of the first airflow channel 2011, the shape of the water-blocking component 100 can be limited to ensure the stability of the water-blocking component 100.

[0084] Among them, the connecting plate 3 and the channel wall 20111 of the first airflow channel 2011 have a limiting groove 31, and the other has a limiting protrusion that cooperates with the limiting groove 31. Through the cooperation of the limiting protrusion and the limiting groove, on the one hand, the water-blocking component 100 can be guided during the installation process to ensure that the water-blocking component 100 is stably and accurately set in the preset position. On the other hand, after the water-blocking component 100 is installed in place, the limiting protrusion can cooperate with the groove wall of the limiting groove to limit the water-blocking component 100 in the axial direction of the pipe joint 201, ensuring the stability of the water-blocking component 100.

[0085] Since some water adheres to the channel wall 20111 of the first airflow channel 2011 and moves upward under the drive of the airflow, in order to prevent the water from moving upward into the air duct assembly 400 and affecting the energy efficiency of the air duct assembly 400, the water baffle 100 also has the function of blocking condensate water, causing the condensate water to be blocked and drip downward.

[0086] Specifically, as shown in Figures 10-13, the water-blocking component 100 further includes at least one baffle 4. The baffle 4 is disposed on the side of the second baffle 2 facing the first baffle 1 and one side of the baffle 4 is connected to the connecting plate 3 to block the upward flow of condensate on both sides of the second baffle 2 near the channel wall 20111 of the first airflow channel 2011. The second end 2013 to the first end 2012 of the baffle 4 extends in the direction close to the first baffle 1 to avoid water and lint accumulating above the baffle 4 and improve the user experience.

[0087] Referring to Figures 5 and 12, one axial end of the outer cylinder 200 is a closed end and the other axial end is an open end. The pipe joint 201 is located near the closed end to make the drying of clothes more uniform and to facilitate the arrangement of the internal structure of the clothes processing device.

[0088] The garment handling apparatus according to a second aspect of this application includes the garment handling tube assembly described above.

[0089] As shown in Figures 1 and 5, the garment handling device further includes: an air duct assembly 400, which defines an air duct cavity 401, the air duct cavity 401 having an air inlet 402 and an air outlet 403; the air inlet 402 is connected to the first airflow channel 2011, and the air outlet 403 is connected to the inner cavity 203 of the outer cylinder.

[0090] Referring to Figures 1 and 5, the garment processing device also includes a connecting pipe 500, which is connected between the air duct assembly 400 and the pipe connector 201 and defines a second airflow channel, which connects the air inlet 402 and the first airflow channel 2011.

[0091] The connecting pipe 500 can be set vertically to avoid airflow loss. Furthermore, due to the water baffle 100, water is not easily allowed to enter the connecting pipe 500, thus preventing water accumulation in the connecting pipe 500 from affecting the energy efficiency of the drying process.

[0092] Inside the garment processing device, the airflow in the air duct cavity 401 is driven by a fan to enter the garment processing cavity and participate in the drying and lint removal of the garments. After being fully processed with the garments, the airflow is discharged through the first airflow channel 2011 defined by the pipe joint 201 of the outer cylinder 200. The airflow discharged from the garment processing cavity returns to the air duct cavity 401 through the second airflow channel defined by the connecting pipe 500 and the air inlet 402. After entering the air duct cavity 401, the airflow is first filtered, then processed by the evaporator and condenser, and then flows out of the air duct cavity 401 through the air outlet 403.

[0093] A specific embodiment of the garment processing device is described below with reference to the accompanying drawings.

[0094] As shown in Figures 1-13, the garment processing device includes: a garment processing drum assembly, an air duct assembly 400, and a connecting pipe 500.

[0095] The garment processing drum assembly includes an outer drum 200, an inner drum 300, and a water-blocking component 100. The outer drum 200 extends axially in the horizontal direction or is inclined relative to the horizontal direction. The inner drum 300 is rotatably disposed in the inner cavity 203 of the outer drum. The inner cavity of the inner drum 300 is used to accommodate garments. The garments define a garment processing chamber in the inner cavity of the inner drum 300. The garments are washed, dehydrated, or dried in the garment processing chamber. A pipe connector 201 is located on the upper part of the outer peripheral wall of the outer drum 200. The pipe connector 201 defines a first airflow channel 2011 that communicates with the inner cavity 203 of the outer drum. The first airflow channel 2011 defined by the pipe connector 201 communicates with the garment processing chamber. One end of the pipe connector 201 defines an airflow outlet for the garment processing chamber.

[0096] An air duct assembly 400 is disposed above the garment processing drum assembly. The air duct assembly 400 defines an air duct cavity 401, which has an air inlet 402 and an air outlet 403. The air inlet 402 communicates with the first airflow channel 2011, and the air outlet 403 communicates with the inner cavity 203 of the outer drum. The airflow outlet of the garment processing cavity and the air inlet 402 of the air duct cavity 401 are axially opposite to each other on the pipe joint 201. A vertically extending connecting pipe 500 is provided between the airflow outlet of the garment processing cavity and the air inlet 402 of the air duct cavity 401.

[0097] When the clothes are being dried in the clothes processing chamber, the airflow in the air duct chamber 401 of the clothes processing device is driven by the fan to enter the clothes processing chamber and participate in the drying and lint removal of the clothes. After being fully processed with the clothes, the airflow is discharged through the first airflow channel 2011 defined by the pipe joint 201 of the outer cylinder 200. The airflow discharged from the clothes processing chamber returns to the air duct chamber 401 through the second airflow channel defined by the connecting pipe 500 and the air inlet 402. After the airflow enters the air duct chamber 401, it is first filtered, then processed by the evaporator and condenser, and then flows out of the air duct chamber 401 through the air outlet 403.

[0098] The garment processing drum assembly also includes a water baffle 100, which is disposed in the first airflow channel 2011 and is located above the tangent L at the highest point of the intersection line S on the inner peripheral wall of the outer drum 200. When the garment is dehydrated in the garment processing chamber, the water baffle 100 changes the direction of water splashing, so that the water flow bounces back downward under the obstruction of the water baffle 100, thus preventing water from splashing into the air duct assembly 400.

[0099] The cross-section of the first airflow channel 2011 is circular. With the diameter line parallel to the axis of the outer cylinder 200 as the central axis, the channel wall 20111 of the first airflow channel 2011 on one side of the inner cavity 203 away from the outer cylinder mainly receives the splashed water flow, while the channel wall 20111 of the first airflow channel 2011 on the other side of the semicircle faces away from the direction of the water flow and is not easy to come into contact with the water flow to cause splashing.

[0100] The water baffle 100 includes a first baffle 1, a second baffle 2, a connecting plate 3, and a baffle 4. The projection of the first baffle 1 on the plane perpendicular to the axial direction of the pipe joint 201 at least covers the center of the first airflow channel 2011. This ensures that the protection range of the first baffle 1 covers the channel wall 20111 of the first airflow channel 2011 corresponding to the semicircle of the inner cavity 203 away from the outer cylinder. This ensures that the water flow is first turned by the first baffle 1 before contacting the channel wall 20111 of the first airflow channel 2011, thus preventing water from splashing into the inner cavity of the air duct assembly 400.

[0101] The first baffle 1 extends from the second end 2013 to the first end 2012 in a direction away from the inner cavity 203 of the outer cylinder. The angle α between the first baffle 1 and the pipe joint 201 in the axial direction is about 30°. When the water flow impacts the first baffle 1, the first baffle 1 will give the water flow a reaction force in the direction of the inner cavity 203 of the outer cylinder. The reaction force drives the water flow to change direction and the water flow will flow into the outer cylinder 200, thereby preventing the water flow from splashing into the air duct assembly 400 through the first airflow channel 2011.

[0102] The second baffle 2 is located on the side of the inner cavity 203 of the first baffle 1 away from the outer cylinder, and the second end 2013 to the first end 2012 of the second baffle 2 extends towards the first baffle 1. The angle β between the second baffle 2 and the plane perpendicular to the axial direction of the pipe joint 201 is about 25°, so as to ensure that the lint can slide off from above the second baffle 2 under the action of gravity.

[0103] Part of the water flow passes under the first baffle 1 and splashes onto the channel wall 20111 of the first airflow channel 2011 on the side facing the direction of the water flow. The channel wall 20111 of the first airflow channel 2011 will give the water flow splashed on it a reaction force, causing the water flow to spread outward, with some splashing upward. The second baffle 2 can further block the water flow splash outside the air duct assembly 400, ensuring the energy efficiency of the air duct assembly 400.

[0104] The projections of the second baffle 2 and the first baffle 1 onto the plane perpendicular to the axial direction of the pipe joint 201 do not coincide. This allows some airflow to pass more smoothly through the gap between the first baffle 1 and the second baffle 2, reducing the impact of the water-blocking component 100 on airflow. The projections of the second baffle 2 and the first baffle 1 onto the plane parallel to the axial direction of the pipe joint 201 also do not coincide. In other words, the first baffle 1 and the second baffle 2 are not located on the same horizontal plane to avoid the first baffle 1 and the second baffle 2 simultaneously blocking the same plane, causing excessive flow resistance and blockage of the first airflow channel 2011.

[0105] The baffle 4 is located on the side of the second baffle 2 facing the first baffle 1 and one side of the baffle 4 is connected to the connecting plate 3. It blocks the upward flow of condensed water on both sides of the second baffle 2 near the channel wall 20111 of the first airflow channel 2011. The second end 2013 to the first end 2012 of the baffle 4 extends in the direction close to the first baffle 1 to avoid water and lint accumulating on the baffle 4 and improve the user experience.

[0106] The connecting plate 3 is connected to the outer periphery of the second baffle 2, and both ends of the connecting plate 3 are connected to the two ends of the first baffle 1 respectively. The shape of the connecting plate 3 is adapted to the shape of the channel wall 20111 of the first airflow channel 2011. That is, the connecting plate 3 is set along the channel wall 20111 of the first airflow channel 2011. One of the connecting plate 3 and the channel wall 20111 of the first airflow channel 2011 has a limiting groove 31, and the other has a limiting protrusion that cooperates with the limiting groove 31. Through the cooperation of the limiting protrusion and the limiting groove, on the one hand, the water-blocking component 100 can be guided during the installation of the water-blocking component 100 to ensure that the water-blocking component 100 is stably and accurately set in the preset position. On the other hand, after the water-blocking component 100 is installed in place, the limiting protrusion can cooperate with the groove wall of the limiting groove to limit the water-blocking component 100 in the axial direction of the pipe joint 201 to ensure the stability of the water-blocking component 100.

[0107] The connecting plate 3, the first baffle 1, the second baffle 2 and the baffle 4 are integrally formed, and the entire water-blocking component 100 can be fixedly installed in the pipe joint 201 to achieve the fixation of the entire water-blocking component 100.

[0108] The first baffle 1 is provided with a first connecting part 11, and the outer cylinder 200 is provided with a second connecting part 202. The first connecting part 11 and the second connecting part 202 are connected to fix the first baffle 1 in the first airflow channel 2011.

[0109] In some embodiments, the first baffle 1 and the outer cylinder 200 are fixedly connected by fasteners. Specifically, referring to Figures 1-13, the first connecting part 11 includes a first connecting hole, the second connecting part 202 includes a connecting rib 2021 and the connecting rib 2021 is provided with a second connecting hole, and the first baffle 1 is fixed in the first airflow channel 2011 by fasteners and the fasteners pass through the first connecting hole and the second connecting hole.

[0110] The connecting rib 2021 is formed in the shape of a strip to ensure its own stability, thereby ensuring the stability of the first baffle 1. In addition, the projected area of ​​the connecting rib 2021 on the plane perpendicular to the airflow direction is small, so as to avoid the setting of the connecting rib 2021 from affecting the normal flow of airflow.

[0111] Furthermore, to prevent the water-blocking component 100 from affecting the normal flow of air in the first airflow channel 2011, the water-blocking component 100 and the pipe connector 201 and / or the water-blocking component 100 itself define an outlet. The side of the first baffle 1 facing the inner cavity 203 of the outer cylinder defines a first outlet 101 between the first baffle 1 and the channel wall 20111 of the first airflow channel 2011. The second baffle 2 and the first baffle 1 define a second outlet 102. The airflow can flow to the air duct assembly 400 or to the clothing processing chamber through the first outlet 101 defined between the first baffle 1 and the channel wall 20111 of the first airflow channel 2011 and the second outlet 102 defined between the second baffle 2 and the first baffle 1. The water-blocking component 100 reserves two outlets for airflow, ensuring normal airflow during the drying process of the clothing processing device.
