DETAILED DESCRIPTION

[0048] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0050] Reference below Figure 1-Figure 13 A laundry treatment tub assembly according to an embodiment of the present utility model is described.

[0051] The laundry treatment tub assembly according to the embodiment of the present invention may include an outer tub 200 , an inner tub 300 and a water stopper 100 .

[0052] Among them, the pipe joint 201 is arranged on the outer peripheral wall of the outer tube 200, and the pipe joint 201 defines a first air flow channel 2011 connected to the inner cavity 203 of the outer tube. When the clothes are dried in the clothing processing chamber, the humid air in the clothing processing chamber enters the air duct assembly 400 through the first air flow channel 2011 defined by the pipe joint 201, or the dry air in the air duct assembly 400 enters the clothing processing chamber through the first air flow channel 2011 defined by the pipe joint 201.

[0053] Since the first air flow channel 2011 defined by the pipe joint 201 is connected to the clothing processing chamber, when the clothing is dehydrated in the clothing processing chamber, the water flow in the clothing processing chamber will splash onto the wall of the outer drum 200 under the action of centrifugal force, and enter the air duct assembly 400 through the first air flow channel 2011, causing water accumulation in the air duct assembly 400, affecting the drying performance of the air duct assembly 400.

[0054] To this end, an embodiment of the utility model designs a clothing processing drum assembly having a water retaining member 100 in the first air flow channel 2011, thereby being able to change the splashing direction of the water flow through the water retaining member 100, so that the water flow rebounds downward under the obstruction of the water retaining member 100, thereby preventing the water flow from splashing into the air duct assembly 400.

[0055] Furthermore, in order to prevent the setting of the water retaining member 100 from affecting the normal passage of air in the first air flow channel 2011, a flow port is defined between the water retaining member 100 and the pipe joint 201 and / or in the water retaining member 100 itself to allow air to pass through the first air flow channel 2011. Thus, the water retaining member 100 can change the splashing direction of water in the dehydration mode of the clothing processing device without affecting the passage of humid air of the clothing processing device through the first air flow channel 2011 defined by the pipe joint 201 into the air duct assembly 400 in the drying mode, or the passage of dry air in the air duct assembly 400 into the clothing processing chamber through the first air flow channel 2011 defined by the pipe joint 201, so that the water entering the pipe joint 201 rebounds downward under the obstruction of the water retaining member 100, thereby preventing the water from splashing into the air duct assembly 400 and affecting the drying performance of the air duct assembly 400.

[0056] According to the laundry processing drum assembly of the embodiment of the utility model, the laundry processing drum assembly is provided with a water retaining member 100 which can change the splashing direction of water flow without affecting the ventilation in the air flow channel, thereby avoiding water accumulation in the air duct assembly 400 and ensuring the drying performance of the air duct assembly 400.

[0057] The axial direction of the outer drum 200 can extend in the horizontal direction or be inclined relative to the horizontal direction, and the inner drum 300 can be rotatably arranged in the inner cavity 203 of the outer drum. The inner cavity of the inner drum 300 is used to accommodate clothes. The clothes define a clothes processing cavity in the inner cavity of the inner drum 300, and the clothes are washed, dehydrated or dried in the clothes processing cavity. Figure 3 The inner wall of the outer cylinder 200 and the channel wall 20111 of the first air flow channel 2011 have an intersection line S. After passing the intersection line S, the water flow no longer contacts the inner wall of the outer cylinder, and the water flow continues to flow under the action of inertia and gravity. Since the flow direction of the water flow 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 flow will flow through the first air flow channel 2011 through the space below the tangent L. In the cross section perpendicular to the axial direction of the outer cylinder 200, the water retaining member 100 is located on the side of the tangent L of the inner wall of the outer cylinder 200 at the highest point of the intersection line S, away from the inner cavity 203 of the outer cylinder, so as to avoid a large amount of water flow directly impacting the water retaining member 100, affecting the setting stability of the water retaining member 100 and affecting the water retaining effect of the water retaining member 100.

[0058] like Figure 2As shown, the first axial end 2012 of the pipe joint 201 is close to the outer tube 200 and the second axial end 2013 is away from the outer tube 200. In some embodiments, the first axial end 2012 of the pipe joint 201 is the lower end of the pipe joint 201, and the second axial end 2013 of the pipe joint 201 is the lower end of the pipe joint 201; the water retaining member 100 includes a first baffle plate 1, and the first baffle plate 1 gradually deviates from the inner cavity 203 of the outer tube from the second end 2013 to the first end 2012. From the inner cavity 203 of the outer tube from the second end 2013 to the first end 2012, the water flow impacts the first baffle plate 1, and the first baffle plate 1 will give the water flow a reaction force toward the inner cavity 203 of the outer tube. The reaction force drives the water flow to turn, and the water flow will flow into the outer tube 200, thereby avoiding the water flow from splashing into the air duct assembly 400 through the first air flow channel 2011.

[0059] Reference Figure 3 The axial angle α between the first baffle plate 1 and the pipe joint 201 is greater than 20° and less than 45°. On the one hand, it is prevented that the axial angle α between the first baffle plate 1 and the pipe joint 201 is too small, causing part of the water to splash upward and splash into the air duct assembly 400. On the other hand, it is prevented that the axial angle α between the first baffle plate 1 and the pipe joint 201 is too large, causing the projection area of ​​the first baffle plate 1 on the plane perpendicular to the airflow direction to be too large, affecting the normal passage of the airflow in the first airflow channel 2011, and ensuring the flow rate of the airflow.

[0060] like Figure 4 and Figure 10-13 As shown, the channel wall 20111 of the first airflow channel 2011 corresponding to the side of the first baffle plate 1 facing the inner cavity 203 of the outer cylinder faces away from the direction of the water flow, and is not easy to contact with the water flow to cause splashing. There is no need to add a water-blocking structure between the side of the first baffle plate 1 facing the inner cavity 203 of the outer cylinder and the channel wall 20111 of the corresponding first airflow channel 2011, so this part of the space can be used for airflow circulation. Specifically, the flow port includes a first flow port 101, and the first flow port 101 is defined between the side of the first baffle plate 1 facing the inner cavity 203 of the outer cylinder and the channel wall 20111 of the first airflow channel 2011 to ensure the normal passage of airflow in the first airflow channel 2011.

[0061] Reference Fig.10 and Fig.11In some embodiments, the cross-section of the first airflow channel 2011 is formed into a circle, wherein a diameter line parallel to the axial direction of the outer cylinder 200 is taken as the central axis, and a channel wall 20111 of the first airflow channel 2011 corresponding to a semicircle on one side of the inner cavity 203 away from the outer cylinder mainly receives the splashed water flow, and a channel wall 20111 of the first airflow channel 2011 corresponding to a semicircle on the other side faces away from the direction of the water flow, and is not easy to contact with the water flow to cause splashing. By limiting the projection of the first baffle 1 on a 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 a semicircle on one side of the inner cavity 203 away from the outer cylinder, thereby ensuring that the water flow first passes through the first baffle 1 to turn before contacting the channel wall 20111 of the first airflow channel 2011, thereby preventing the water flow from splashing into the inner cavity of the air duct assembly 400.

[0062] In some embodiments, the first baffle 1 and the pipe joint 201 are integrally formed to ensure that the first baffle 1 can be stably disposed in the laundry processing drum assembly.

[0063] The first baffle 1 and the outer cylinder 200 can also be formed separately, and then connected and fixed by welding, bonding, screw connection, etc.

[0064] Specifically, combined Figure 1-Figure 13 In the illustrated embodiment, a first connecting portion 11 is provided on the first baffle 1 , and a second connecting portion 202 is provided on the outer tube 200 . The first connecting portion 11 is connected to the second connecting portion 202 to fix the first baffle 1 in the first air flow channel 2011 .

[0065] In some embodiments, the first baffle 1 and the outer cylinder 200 are fixedly connected by fasteners. Figure 1-Figure 13 The first connection part 11 includes a first connection hole, the second connection part 202 includes a connection rib 2021 and the connection rib 2021 is provided with a second connection hole, the first baffle 1 is fixed in the first air flow channel 2011 by a fastener and the fastener passes through the first connection hole and the second connection hole.

[0066] The connecting rib 2021 is formed into a strip shape to ensure its own stability, thereby ensuring the stability of the first baffle 1. In addition, the projection area of ​​the connecting rib 2021 on a plane perpendicular to the airflow direction is small, thereby avoiding the setting of the connecting rib 2021 affecting the normal circulation of the airflow.

[0067] Reference Figure 1-Figure 4 The water retaining member 100 further includes a second retaining plate 2, which is disposed on a side of the first retaining plate 1 away from the inner cavity 203 of the outer cylinder.

[0068] Since part of the water flow passes through the first baffle plate 1 from under the first baffle plate 1 and splashes onto the channel wall 20111 of the first air flow channel 2011 on the side facing the direction of the water flow, the channel wall 20111 of the first air flow channel 2011 will give a reaction force to the water flow splashing thereon, causing the water flow to scatter outward, part of which splashes upward, and this part of the water flow is easily splashed into the inner cavity of the air duct assembly 400.

[0069] Therefore, by providing the second baffle 2 , water splashing can be further blocked outside the air duct assembly 400 , thereby ensuring the energy efficiency of the air duct assembly 400 .

[0070] Among them, Figure 2 As shown, the second end 2013 of the second baffle 2 extends to the first end 2012 in the direction close to the first baffle 1, whereby the direction of the reaction force given to the water flow by the second baffle 2 is away from downward and toward the side away from the first baffle 1, which can further block the splashing of water flow outside the air duct assembly 400, thereby ensuring the energy efficiency of the air duct assembly 400.

[0071] Reference Figure 3 The angle β between the second baffle plate 2 and the surface perpendicular to the axial direction of the pipe joint 201 is greater than 5° and less than 45°. When the angle between the second baffle plate 2 and the surface perpendicular to the axial direction of the pipe joint 201 is too small, the projection area of ​​the second baffle plate 2 on the plane perpendicular to the airflow direction is larger, which affects the airflow permeability. When the angle between the second baffle plate 2 and the surface perpendicular to the axial direction of the pipe joint 201 is too large, the second baffle plate 2 needs to be set long enough to cover the sputtering path of the water flow, and the production cost is high.

[0072] In addition, there is an airflow dead corner above the second baffle plate 2, and the hair debris on the second baffle plate 2 cannot move toward the air duct assembly 400 under the drive of the airflow. There needs to be a certain angle between the second baffle plate 2 and the surface perpendicular to the axial direction of the pipe joint 201, so that the hair debris on the second baffle plate 2 can slide off the second baffle plate 2 under the action of gravity, avoiding the accumulation of hair debris above the second baffle plate 2 and affecting the user experience.

[0073] like Figure 4 and Figure 10-13 As shown, the flow port also includes a second flow port 102, and a second flow port 102 is defined between the second baffle 2 and the first baffle 1. That is to say, the airflow can flow to the air duct assembly 400 or to the clothing processing chamber through the first flow port 101 defined between the first baffle 1 and the channel wall 20111 of the first airflow channel 2011 and the second flow port 102 defined between the second baffle 2 and the first baffle 1, and the water retaining member 100 reserves two flow ports for the airflow circulation, thereby ensuring the normal flow of the airflow.

[0074] Reference Figure 7 , Fig.10 and Fig.11 The projections of the second baffle plate 2 and the first baffle plate 1 on the plane perpendicular to the axial direction of the pipe joint 201 do not overlap, so that part of the airflow can flow more smoothly through the gap between the first baffle plate 1 and the second baffle plate 2, reducing the impact of the setting of the water retaining member 100 on the airflow circulation.

[0075] Reference Figure 1-Figure 4 and Fig. 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 overlap, that is, the first baffle 1 and the second baffle 2 are not located on the same horizontal plane, so as to avoid the first baffle 1 and the second baffle 2 being blocked at the same plane at the same time, causing excessive flow resistance at that place and causing blockage of the first air flow channel 2011.

[0076] By making the first baffle 1 and the second baffle 2 not be located on the same horizontal plane, the flow resistance can be reduced, the area available for airflow to pass through can be increased, and the normal flow of air can be ensured.

[0077] According to some embodiments of the present invention, the second baffle plate 2 and the pipe joint 201 are integrally formed to achieve fixation of the second baffle plate 2 in the pipe joint 201 .

[0078] Or, according to other embodiments of the present invention, in combination with Figure 1-Figure 13 In the embodiment shown, the second baffle 2 is connected to the first baffle 1 so as to be fixed in the first air flow channel 2011 through the first baffle 1. Since the first baffle 1 is fixedly disposed in the pipe joint 201, the second baffle 2 fixedly connected to the first baffle 1 can also be fixedly disposed in the pipe joint 201, which simplifies the production difficulty of the outer tube 200 and reduces the production cost.

[0079] Specifically, Figure 6-Figure 8 As shown, the second baffle plate 2 and the first baffle plate 1 can be connected by a connecting plate 3. The water retaining member 100 also includes a connecting plate 3, which is connected to the outer periphery of the second baffle plate 2, and the two ends of the connecting plate 3 are respectively connected to the two ends of the first baffle plate 1. The connecting plate 3, the first baffle plate 1 and the second baffle plate 2 are integrally formed. Thus, the entire water retaining member 100 can be fixed together in the pipe joint 201 to achieve the fixation of the entire water retaining member 100.

[0080] Furthermore, the arrangement of the connecting plate 3 can improve the strength of the first baffle plate 1 and the second baffle plate 2, ensure the stability of the arrangement of the first baffle plate 1 and the second baffle plate 2, and prevent the first baffle plate 1 and the second baffle plate 2 from being damaged by external forces.

[0081] Combination Figure 10-13In the embodiment shown, 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 arranged along the channel wall 20111 of the first airflow channel 2011. On the one hand, it can avoid the airflow passing through the opening, thereby preventing the setting of the connecting plate 3 from affecting the normal circulation of the 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 retaining member 100 can be limited to ensure the stability of the setting of the water retaining member 100.

[0082] Among them, there is a limiting groove 31 in the channel wall 20111 of the connecting plate 3 and the first air flow channel 2011, and the other is provided with a limiting protrusion cooperating with the limiting groove 31. Through the cooperation between the limiting protrusion and the limiting groove, on the one hand, the water retaining member 100 can be guided during the installation of the water retaining member 100 to ensure that the water retaining member 100 is stably and accurately set at the preset position. On the other hand, after the water retaining member 100 is installed in place, the limiting protrusion can cooperate with the groove wall of the limiting groove to limit the water retaining member 100 in the axial direction of the pipe joint 201 to ensure the stability of the setting of the water retaining member 100.

[0083] Since there is some water attached to the channel wall 20111 of the first air flow channel 2011 and moves upward under the drive of the air flow, in order to prevent the water flow from moving upward into the air duct assembly 400 and affecting the energy efficiency of the air duct assembly 400, the water retaining member 100 also has the function of blocking condensed water, causing the condensed water to be blocked from dripping downward.

[0084] Specifically, Figure 10-13 As shown, the water retaining member 100 also includes at least one retaining rib 4, which is arranged on the side of the second baffle plate 2 facing the first baffle plate 1 and one side of the retaining rib 4 is connected to the connecting plate 3 to block the condensed water from flowing upward on both sides of the channel wall 20111 of the second baffle plate 2 close to the first air flow channel 2011, and the second end 2013 of the retaining rib 4 extends to the first end 2012 in the direction close to the first baffle plate 1 to avoid water flow and hair debris from accumulating above the retaining rib 4, thereby improving the user experience.

[0085] Reference Figure 5 and Fig.12 One axial end of the outer drum 200 is a closed end and the other axial end is an open end. The pipe joint 201 is arranged close to the closed end to make the clothes drying more uniform and facilitate the arrangement of the internal structure of the clothes processing device.

[0086] A clothes processing device according to an embodiment of the second aspect of the utility model comprises a clothes processing drum assembly of the above embodiment.

[0087] like Figure 1 and Figure 5As shown, the clothing processing device also includes: an air duct component 400, the air duct component 400 defines an air duct cavity 401, and the air duct cavity 401 has an air inlet 402 and an air outlet 403; the air inlet 402 is connected to the first air flow channel 2011, and the air outlet 403 is connected to the inner cavity 203 of the outer drum.

[0088] Reference Figure 1 and Figure 5 The clothing processing device further includes a connecting pipe 500 , which is connected between the air duct assembly 400 and the pipe joint 201 and defines a second air flow channel, which connects the air inlet 402 and the first air flow channel 2011 .

[0089] The connecting pipe 500 can be arranged in a vertical direction to avoid airflow loss, and due to the arrangement of the water retaining member 100, water is not easy to enter the connecting pipe 500, thereby avoiding water accumulation in the connecting pipe 500 to affect the energy efficiency of the drying process.

[0090] In the clothing processing device, the airflow in the air duct cavity 401 is driven by the fan to enter the clothing processing cavity, participate in the drying and hair removal of the clothing, and after being fully processed with the clothing, the airflow is discharged through the first airflow channel 2011 defined by the pipe joint 201 of the outer cylinder 200, and the airflow discharged from the clothing 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 the airflow enters the air duct cavity 401, it is first filtered, then processed by the evaporator and the condenser, and then flows out of the air duct cavity 401 through the air outlet 403.

[0091] A specific embodiment of the clothes treating device is described below with reference to the accompanying drawings.

[0092] like Figure 1-Figure 13 As shown, the clothes treating device includes: a clothes treating drum assembly, an air duct assembly 400 and a connecting pipe 500 .

[0093] Among them, the clothing processing drum assembly includes an outer drum 200, an inner drum 300 and a water stopper 100. The axial direction of the outer drum 200 extends in the horizontal direction or is inclined relative to the horizontal direction. The inner drum 300 can be rotatably arranged in the inner cavity 203 of the outer drum. The inner cavity of the inner drum 300 is used to accommodate clothing. The clothing defines a clothing processing cavity in the inner cavity of the inner drum 300. The clothing is washed, dehydrated or dried in the clothing processing cavity. A pipe joint 201 is provided at the upper position of the outer peripheral wall of the outer drum 200. The pipe joint 201 defines a first air flow channel 2011 connected to the inner cavity 203 of the outer drum. The first air flow channel 2011 defined by the pipe joint 201 is connected to the clothing processing cavity. One end of the pipe joint 201 defines an air flow outlet of the clothing processing cavity.

[0094] The air duct assembly 400 is arranged above the clothes processing drum assembly, and the air duct assembly 400 defines an air duct cavity 401, and the air duct cavity 401 has an air inlet 402 and an air outlet 403, the air inlet 402 is communicated with the first air flow channel 2011, and the air outlet 403 is communicated with the inner cavity 203 of the outer drum. The air flow outlet of the clothes processing cavity and the air inlet 402 of the air duct cavity 401 are arranged opposite to each other in the axial direction of the pipe joint 201, and a connecting pipe 500 extending vertically is arranged between the air flow outlet of the clothes processing cavity and the air inlet 402 of the air duct cavity 401.

[0095] When the clothes are being dried in the clothes processing chamber, in the clothes processing device, the airflow in the air duct chamber 401 is driven by the fan to enter the clothes processing chamber, and participates in the drying and hair 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, and 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 the condenser, and then flows out of the air duct chamber 401 through the air outlet 403.

[0096] The clothing processing drum assembly also includes a water retaining member 100, which is disposed in the first air flow channel 2011 and is located above the tangent L of the inner wall of the outer drum 200 at the highest point of the intersection S. When the clothing is dehydrated in the clothing processing chamber, the water retaining member 100 changes the splashing direction of the water flow, so that the water flow rebounds to the lower side under the obstruction of the water retaining member 100, thereby preventing the water flow from splashing into the air duct assembly 400.

[0097] The cross-section of the first airflow channel 2011 is formed into a circle, wherein a diameter line parallel to the axial direction of the outer cylinder 200 is taken as the central axis, and a channel wall 20111 of the first airflow channel 2011 corresponding to a semicircle on one side away from the inner cavity 203 of the outer cylinder mainly receives the splashed water flow, while a channel wall 20111 of the first airflow channel 2011 corresponding to a semicircle on the other side faces away from the direction of the water flow and is not easy to contact with the water flow and cause splashing.

[0098] The water retaining member 100 comprises a first baffle plate 1, a second baffle plate 2, a connecting plate 3 and a retaining rib 4. The projection of the first baffle plate 1 on a surface perpendicular to the axial direction of the pipe joint 201 at least covers the center of the first air flow channel 2011, thereby ensuring that the protection range of the first baffle plate 1 covers the channel wall 20111 of the first air flow channel 2011 corresponding to the semicircle on one side of the inner cavity 203 away from the outer cylinder, thereby ensuring that the water flow is first turned through the first baffle plate 1 before contacting the channel wall 20111 of the first air flow channel 2011, thereby avoiding water flow splashing into the inner cavity of the air duct assembly 400.

[0099] The second end 2013 of the first baffle 1 extends to the first end 2012 in a direction away from the inner cavity 203 of the outer cylinder, and the axial angle α between the first baffle 1 and the pipe joint 201 is approximately 30°. When water flows impacting 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 turn, and the water flow will flow into the outer cylinder 200, thereby avoiding the water flow from splashing into the inside of the air duct assembly 400 through the first air flow channel 2011.

[0100] The second baffle plate 2 is arranged on a side of the first baffle plate 1 away from the inner cavity 203 of the outer cylinder, and the second end 2013 of the second baffle plate 2 extends to the first end 2012 in a direction close to the first baffle plate 1, and the angle β between the second baffle plate 2 and the surface perpendicular to the axial direction of the pipe joint 201 is approximately 25°, so as to ensure that hair scraps can slide off from above the second baffle plate 2 under the action of gravity.

[0101] Part of the water flow passes through the first baffle plate 1 from under the first baffle plate 1 and splashes onto the channel wall 20111 of the first air flow channel 2011 on the side facing the direction of the water flow. The channel wall 20111 of the first air flow channel 2011 will give a reaction force to the water flow splashing thereon, so that the water flow scatters outward, and part of it splashes upward. The second baffle plate 2 can further block the splashing of water flow outside the air duct assembly 400, thereby ensuring the energy efficiency of the air duct assembly 400.

[0102] 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 overlap, so that part of the airflow can flow more smoothly through the gap between the first baffle 1 and the second baffle 2, reducing the influence of the setting of the water retaining member 100 on the airflow. 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 overlap, that is, the first baffle 1 and the second baffle 2 are not located on the same horizontal plane, so as to avoid the first baffle 1 and the second baffle 2 being blocked at the same plane at the same time, causing excessive flow resistance at that place, resulting in blockage of the first airflow channel 2011.

[0103] The blocking rib 4 is arranged on the side of the second baffle plate 2 facing the first baffle plate 1 and one side of the blocking rib 4 is connected to the connecting plate 3 to block the condensed water from flowing upward on both sides of the channel wall 20111 of the second baffle plate 2 close to the first air flow channel 2011. The second end 2013 of the blocking rib 4 extends to the first end 2012 in the direction close to the first baffle plate 1 to avoid water flow and hair debris from accumulating above the blocking rib 4, thereby improving the user experience.

[0104] The connecting plate 3 is connected to the outer periphery of the second baffle plate 2, and the two ends of the connecting plate 3 are respectively connected to the two ends of the first baffle plate 1. 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 arranged along the channel wall 20111 of the first airflow channel 2011, and the connecting plate 3 and the channel wall 20111 of the first airflow channel 2011 have a limiting groove 31, and the other is provided with a limiting protrusion that cooperates with the limiting groove 31. Through the cooperation between the limiting protrusion and the limiting groove, on the one hand, the water retaining member 100 can be guided during the installation of the water retaining member 100 to ensure that the water retaining member 100 is stably and accurately set at the preset position. On the other hand, after the water retaining member 100 is installed in place, the limiting protrusion can cooperate with the groove wall of the limiting groove to limit the water retaining member 100 in the axial direction of the pipe joint 201 to ensure the stability of the setting of the water retaining member 100.

[0105] The connecting plate 3 , the first baffle plate 1 , the second baffle plate 2 and the baffle rib 4 are integrally formed, and the entire water baffle 100 can be fixedly disposed in the pipe joint 201 together to achieve fixation of the entire water baffle 100 .

[0106] The first baffle plate 1 is provided with a first connecting portion 11 , and the outer tube 200 is provided with a second connecting portion 202 . The first connecting portion 11 is connected to the second connecting portion 202 so that the first baffle plate 1 is fixed in the first air flow channel 2011 .

[0107] In some embodiments, the first baffle 1 and the outer cylinder 200 are fixedly connected by fasteners. Figure 1-Figure 13 The first connection part 11 includes a first connection hole, the second connection part 202 includes a connection rib 2021 and the connection rib 2021 is provided with a second connection hole, the first baffle 1 is fixed in the first air flow channel 2011 by a fastener and the fastener passes through the first connection hole and the second connection hole.

[0108] The connecting rib 2021 is formed into a strip shape to ensure its own stability, thereby ensuring the stability of the first baffle 1. In addition, the projection area of ​​the connecting rib 2021 on a plane perpendicular to the airflow direction is small, thereby avoiding the setting of the connecting rib 2021 affecting the normal circulation of the airflow.

[0109] Furthermore, in order to prevent the setting of the water retaining member 100 from affecting the normal passage of air in the first airflow channel 2011, a flow port is defined between the water retaining member 100 and the pipe joint 201 and / or the water retaining member 100 itself, a first flow port 101 is defined between the side of the inner cavity 203 of the outer tube facing the first baffle 1 and the channel wall 20111 of the first airflow channel 2011, and a second flow port 102 is defined between the second baffle 2 and the first baffle 1. The airflow can flow to the air duct assembly 400 or to the clothing processing chamber through the first flow port 101 defined between the first baffle 1 and the channel wall 20111 of the first airflow channel 2011 and the second flow port 102 defined between the second baffle 2 and the first baffle 1 respectively. The water retaining member 100 reserves two flow ports for airflow circulation, thereby ensuring the normal flow of airflow in the clothing processing device during the drying process.
