[0065] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the principles of this application and are not intended to limit the scope of protection of this application. In the various drawings of this application, features with the same structure or similar function are represented by the same reference numerals.

[0066] like Figure 1 As shown, the air duct system for a garment handling apparatus according to an embodiment of this application includes an air duct structure 1 and a pipe 2, wherein the pipe 2 is used to fluidly connect the garment handling chamber of the garment handling apparatus to the air duct structure 1. The air duct structure 1 may be provided with a first connecting portion 11, and the pipe 2 may be provided with a second connecting portion 21, and the first connecting portion 11 and the second connecting portion 21 may advantageously be configured to fit together to achieve the connection between the air duct structure 1 and the pipe 2. Thus, the connection between the air duct structure 1 and the pipe 2 can be easily achieved without the need for additional connectors.

[0067] Here, the garment handling apparatus according to an embodiment of this application, including the aforementioned air duct system, can be particularly a drum-type garment handling apparatus, whose garment handling chamber can be an outer tub used to define the washing space. For example... Figure 1 and Figure 2 As shown, the air duct structure 1 of the air duct system is at least partially located above the outer barrel 20. It should be understood that... Figure 1 and Figure 2Only a portion of the outer casing is shown, specifically including the mounting base located at the corresponding air outlet of the outer casing. Due to the limitations of standard casing dimensions, the space above the outer casing 20 is typically limited, which poses difficulties for the fluid connection between the duct structure 1 and the outer casing 20. The duct system according to embodiments of this application overcomes this difficulty by achieving a compact connection arrangement structure above the outer casing 20 through the shaped fit of the first connecting portion 11 and the second connecting portion 21, thereby advantageously adapting to the limited installation space above the outer casing 20. It should be understood that this application is not limited to this; the duct system according to embodiments of this application can also be used to address other confined installation spaces, not just the confined space above the outer casing 20.

[0068] Additionally or alternatively, the garment handling apparatus according to embodiments of this application can be a washer-dryer combo, particularly a washer-dryer combo with a heat pump module. Washer-dryers with heat pump modules are also commonly referred to as heat pump washer-dryers. With the increasing popularity of heat pump washer-dryers, standard-sized heat pump washer-dryers are gradually becoming a new trend in the laundry industry. Typically, the heat pump system of such a washer-dryer combo can be located within or integrated with the duct system, and the duct structure of the duct system is at least partially located above the outer tub, with the two connected by pipes, particularly corrugated pipes. Due to the addition of the heat pump system, limited installation space becomes a major challenge. Common corrugated pipe installation methods include radial outer clamp installation, which uses high-tension clamps to secure the corrugated pipe and prevent it from falling off; however, the limited installation space of heat pump washer-dryers makes it inconvenient to install high-tension clamps. Therefore, the duct system of this application embodiment can achieve a stable connection between the pipe, especially the corrugated pipe and the duct structure without the need for additional clamps or other separate fasteners, making it particularly suitable for use in heat pump washer-dryer combos.

[0069] In some embodiments, the duct 2 may be in the form of a corrugated pipe. Additionally or alternatively, in some embodiments, the duct structure 1 may be provided by the fan housing of the garment handling device. The connection between the duct 2 and the outer tub 20 may be achieved via a separate fastener 201 (such as...). Figure 2 As shown in the figure.

[0070] In some alternative embodiments, such as Figure 2As shown, the second connecting portion 21 can mate with the first connecting portion 11 from the radially inner side. This facilitates coupling the second connecting portion 21 to the first connecting portion 11, particularly when the operating space of the duct structure 1 is larger than the operating space of the pipe 2. In the case of a heat pump washer-dryer combo according to an embodiment of this application, the duct structure 1 is located above the pipe 2 and has a larger operating space than the operating space of the pipe 2 (i.e., the internal passage of the pipe 2). Additionally, due to the limited space between the outer tub and the duct structure, other parts of the duct structure 1 may obstruct the view of the first connecting portion 11 downwards, making it inconvenient to install individual fasteners. Therefore, connecting the second connecting portion 21 of the pipe 2 from the radially inner side of the first connecting portion 11 of the duct structure 1 advantageously facilitates the corresponding connection operation.

[0071] In some alternative embodiments, the second connecting portion 21 may be at least partially elastic. Thus, it can be coupled to the first connecting portion 11 by causing elastic deformation of the second connecting portion 21.

[0072] In some alternative embodiments, the first connecting portion 11 and the second connecting portion 21 may be interference-fitted at least in the radial direction of the pipe 2. Thus, a sealed connection between the first connecting portion 11 and the second connecting portion 21 can be achieved solely through the interference fit. Here, the sealed connection may include at least one of an airtight connection and a liquid-tight connection. Here, the term "radial direction" may specifically refer to the radial direction at the second connecting portion 21 of the pipe 2 in some embodiments; that is, in other embodiments, the central axis of the pipe 2 may be curved.

[0073] In some alternative embodiments, in order to achieve shape fit, such as Figure 2 and Figure 3As shown, the first connecting portion 11 may have a first groove 111, and the second connecting portion 21 may have a second groove 211, and the first groove 111 and the second groove 211 are configured to open in opposite directions so that they can engage with each other. In particular and preferably, the first groove 111 and the second groove 211 may both have a generally U-shaped cross-sectional shape. However, this application is not limited to this, and the first groove 111 and the second groove 211 may also have other cross-sectional shapes that allow them to engage with each other. Specifically, in some embodiments of the garment handling apparatus according to this application, particularly in embodiments where the duct structure 1 is located above the pipe 2, such as in the washer-dryer embodiment with a heat pump module mentioned above, the duct structure 1 and the pipe 2 are arranged such that the first groove 111 of the first connecting portion 11 opens upward and the second groove 211 of the second connecting portion 21 opens downward. It should be understood that, in the context, the term "upward" can mean vertically upward or upward at an angle relative to the vertical direction. The term "downward" is similarly used. Furthermore, in some other embodiments, the duct structure 1 and the pipe 2 may also be oriented in directions other than the vertical direction.

[0074] In some alternative embodiments, to form the first groove 111 and the second groove 211, the first connecting portion 11 and the second connecting portion 21 may respectively have a bent first wall 112 and a bent second wall 212. For example... Figure 2 , Figure 3 , Figures 5 to 7 As shown, the first wall 112 is bent relative to the other portions of the first connecting portion 11 adjacent to the first wall 112, particularly in an upward-opening U-shape, thereby forming the first groove 111 with the other portions of the first connecting portion 11. Correspondingly, the second wall 212 is bent relative to the other portions of the second connecting portion 21 adjacent to the second wall 212, particularly in an downward-opening inverted U-shape, thereby forming the second groove 211 with the other portions of the second connecting portion 21. In this way, the first groove 111 and the second groove 211 can be easily formed.

[0075] Furthermore, in some alternative embodiments, the end of the first wall 112 may extend into the second groove 211, and the end of the second wall 212 may extend into the first groove 111. This advantageously achieves a simple fit between the two.

[0076] Preferably, in some optional embodiments, the first wall 112 is bent radially inward relative to the other portion of the first connecting portion 11 adjacent to the first wall 112, and the second wall 212 is bent radially outward relative to the other portion of the second connecting portion 21 adjacent to the second wall 212, thereby facilitating the second connecting portion 21 to engage with the first connecting portion 11 from the radially inward side of the first connecting portion 11.

[0077] Preferably, in some optional embodiments, the end of the first wall 112 extends into the inner bottom surface of the second groove 211, and the end of the second wall 212 extends into the inner bottom surface of the first groove 111. In this way, the connection stability between the first connecting portion 11 and the second connecting portion 21 can be improved to a greater extent.

[0078] In particular, in some alternative embodiments, especially as Figure 6 and Figure 7 As shown, the end of the second wall 212 is positioned opposite to the other portions 213 of the second connecting portion 21 adjacent to the second wall 212 to define a channel allowing the end of the first wall 112 to pass through and enter the second groove 211. In this way, the opposing portions 213 and the ends of the second wall 212, i.e., the structure of the second connecting portion 21 itself, can provide a vertical positional constraint on the first wall 112. Specifically, as... Figure 6 and Figure 7 As shown, the other portion 213 of the second connection 21 extends further in the radial direction from the central axis of the pipe 2 than the end of the second wall 212.

[0079] Preferably, the distance between the end of the second wall 212 and the other portion 213 of the second connecting portion 21 adjacent to the second wall 212 (i.e., the width of the channel) is approximately equal to the thickness W of the first wall 112 (see...). Figure 5 Therefore, the first wall 112 passing through the channel can be confined to a corresponding vertical position, which also helps to improve the stability of the connection to some extent. Here, the term "approximately equal to" can include within the allowable range of manufacturing tolerances, and can also include equal to or slightly less than to achieve a certain degree of interference fit.

[0080] In some alternative embodiments, the first connecting portion 11 and the second connecting portion 21 may be provided with at least one sealing protrusion 214 and at least one sealing recess 113, the sealing protrusion 214 and the sealing recess 113 being shaped to fit each other for additional sealing. In the illustrated embodiment, the sealing protrusion 214 is disposed in the second connecting portion 21 and the sealing recess 113 is disposed in the first connecting portion 11, but they can also be arranged in reverse. The interlocking of the sealing protrusion and the sealing recess enables multi-dimensional sealing, further enhancing the sealing performance of the connection between the pipe 2 and the duct structure 1.

[0081] In some alternative embodiments, such as Figures 1-3As shown, the air duct system according to an embodiment of this application may further include a fixing part 3, which is adapted to further fix the second connecting part 21 to the first connecting part 11. The fixing part 3 can additionally enhance the connection reliability between the pipe 2 and the air duct structure 1, and prevent accidental separation between the two connecting parts. In some embodiments of the garment handling apparatus according to this application, particularly in embodiments where the air duct structure 1 is located above the pipe 2, such as the washer-dryer with a heat pump module mentioned above, the fixing part 3 of the air duct system presses the second connecting part 21 against the first connecting part 11 downwards (i.e., the axial direction of the fixing part 3 is oriented in the vertical direction).

[0082] Preferably, such as Figure 2 and Figure 3 As shown, the fixing part 3 can press against the second connecting part 21 and is fixedly connected to the air duct structure 1. Alternatively or additionally, the fixing part 3 may have a positioning part 33 for positioning it relative to the second connecting part 21. This facilitates the positioning of the fixing part 3 and its engagement with the second connecting part 21. Alternatively or additionally, the air duct structure 1 may include an upwardly opening air duct base 100, with the first connecting part 11 configured as an opening at the bottom of the air duct base 100, and the fixing part 3 adapted to be installed from inside the air duct base 100. This allows the fixing part 3 to be installed from inside the air duct base with a bottom opening, making the installation process visible downwards and providing sufficient operating space.

[0083] Furthermore, such as Figure 1 As shown, the fixing part 3 may include a ring frame 31 and a pair of lugs 32 arranged opposite to each other on both sides of the ring frame 31. The ring frame 31 is configured to cover the outer bottom surface of the second groove 211 of the second connecting part 21 (i.e., Figure 7 The top surface shown has a positioning protrusion 215, and the lug 32 is configured to be connected to the duct structure 1 via a fastener. Here, the fastener can refer to a screw. The shape of the ring frame 31 can be rectangular, circular, or other suitable.

[0084] Preferably, the lug 32 and the ring frame 31 are located at different heights along the axial direction of the fixing part 3, particularly the lug 32 protruding upwards relative to the ring frame 31. Accordingly, as Figure 4As shown, the duct base 100 of the duct structure 1 may include a surface 12 with an open structure, on which a protruding mounting boss 13 is provided to receive a lug 32. Further, the lug 32 may have a through hole, allowing a fixing connector to pass through the through hole and connect to the mounting boss 13, particularly via a threaded connection. In this case, the positioning portion 33 may be implemented as a positioning recess provided in the ring frame 31, particularly on its lower surface facing the second connecting portion 21, for receiving a positioning protrusion 215 on the second wall 212 of the second connecting portion 21. However, this is not a limitation; the positioning recess and the positioning protrusion may also be arranged in reverse order.

[0085] This application provides a pipe installation structure design that effectively addresses confined installation spaces. This design allows for quick and easy connection of pipes and ductwork structures within limited installation space, particularly enabling pipe installations that are difficult or impossible to achieve using traditional methods under space constraints. Furthermore, this design allows for pipe installation and disassembly in a single direction, simplifying operation, increasing installation cycle time and production efficiency on factory production lines, and reducing the difficulty of after-sales disassembly and reassembly. In addition, this design can achieve multi-dimensional sealing by adding additional features such as axial and / or radial bosses at the connection points, further improving sealing reliability.
