[0002] Currently, the drying module in washer-dryer combos is integrated inside the washing machine. This module includes an air inlet and an air outlet. The air inlet receives low-temperature, high-humidity air, while the air outlet discharges high-temperature, low-humidity air for drying. The pipes connecting to the air inlet and outlet use flexible hoses and hose connectors. The hose connectors are typically spiral-type. However, because the washing machine's design maximizes the washing chamber space, the installation space for other internal components is limited. The spiral-type hose connectors are inconvenient for disassembly and assembly, presenting a drawback. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-4 As shown in the figure, this embodiment discloses a duct connection structure for the drying module of a washer-dryer combo, including a drying module 1. The drying module 1 has a first interface 11 and a second interface 12. The first interface 11 is the air outlet of the drying module, and the second interface 12 is the air inlet of the drying module. A ring body 2 is installed on each of the second interfaces 12. A ring body 2 can also be installed on the first interface 11. Since a filter screen is also installed at the second interface 12, the duct connected to the second interface 12 requires more frequent disassembly and cleaning. Therefore, the following description only focuses on the case where a ring body 2 is installed on the second interface 12.

[0022] like Figure 2 As shown, the ring body 2 is a circular ring structure. One end of the ring body 2 is inserted into the second interface 12. A pipe 7 is installed on the outer wall of the ring body 2. The pipe 7 is a flexible hose. The ring body 2 is inserted into the pipe 7. The outer wall of the pipe 7 is tightly wrapped between the ring body 2 and the pipe 7 by a metal clip to fix the ring body 2 and the pipe 7 to each other.

[0023] like Figure 4 As shown, the ring body 2 includes two ring portions 21 and 22. Ring portions 21 and 22 are alternately arranged and connected along the circumference of the ring body 2 to form a ring shape. Both ring portions 21 and 22 are arc-shaped. Ring portion 22 is made of a soft material; preferably, it is made of rubber or silicone. The arc-shaped length of ring portion 21 has grooves 211 at both ends, and the arc-shaped length of ring portion 22 has corresponding protrusions 221. The protrusions 221 are inserted into the grooves 211. A pin 23 is installed on ring portion 21, and the pin 23 is inserted into ring portion 21 with an interference fit, passing through the protrusions 221.

[0024] By setting ring part 21 and ring part 22, the compression of ring body 2 allows ring parts 21 to move closer to each other, thereby changing the inner diameter.

[0025] like Figure 2 As shown, a rod 3 is mounted on a ring 2. A pin 6 is inserted into the ring 2 along its axial direction. A second pin 6 is mounted on the rod 3 and passes radially through the ring 2. The pin 6 is interference-fitted with the ring 2. The rod 3 is a metal rod, and the rod 3 is clearance-fitted with the ring 2. The rod 3 includes an extension rod 31, on which a second ring 4 is mounted. The second ring 4 is inserted into the second interface 12 and is elliptical in shape. The second ring 4 is coaxially arranged with the ring 2 and spaced apart axially. Multiple second rings 4 are provided; preferably, two second rings 4 are used.

[0026] like Figure 3As shown, rod 3 connects to the two long shaft ends of ring 4. Specifically, extension rod 31 is threaded through the long shaft ends of ring 4. A connecting rod 5 is connected between the two long shaft ends of ring 4. The connecting rod 5 is an arc-shaped rod with flexibility and is made of plastic. Ring 4 has insertion holes 41. Both ends of the connecting rod 5 are inserted into the insertion holes 41. Extension rod 31 passes through the connecting rod 5 to limit its position.

[0027] When the first ring 21 is squeezed, the second ring 22 is compressed. The first ring 21 drives the second ring 4 through the rod 3, causing the second ring 4 to deform and shorten the length of its major axis.

[0028] like Figure 2 As shown, the inner wall of the second interface 12 is provided with a protrusion 121. The protrusion 121 protrudes radially inward along the inner wall of the second interface 12 to form a ring structure. Multiple protrusions 121 are spaced apart along the axial direction of the second interface 12. The number of protrusions 121 is not less than the number of rings 4.

[0029] The protrusion 121 includes a wall surface 1211 located on the side away from the annular body 2. The end face of the annular body 4 on the side close to the annular body 2 abuts against the wall surface 1211. The length of the major axis of the annular body 4 is greater than the inner diameter of the protrusion 121. The two ends of the major axis of the annular body 4 are squeezed so that the length of the major axis of the annular body 4 is less than the inner diameter of the protrusion 121, thereby allowing the annular body 4 to pass through the protrusion 121.

[0030] The ring body 2 is equipped with a sealing gasket 8. The outer peripheral wall of the sealing gasket 8 is in contact with the inner peripheral wall of the second interface 12. The two axial ends of the sealing gasket 8 abut against the ring body 2 and the protrusion 121, respectively.

[0031] During installation, squeeze the two ring bodies 2 on both sides so that the length of the major axis of the second ring body 4 is less than the inner diameter of the protrusion 121, allowing the second ring body 4 to pass through the protrusion 121. At the same time, when the first ring body 2 is inserted into the second interface 12, the sealing gasket 8 is compressed axially. When the first ring body 2 is released, the sealing gasket 8 rebounds, so that the end face of the second ring body 4 near the first ring body 2 abuts against the wall surface 1211 to complete the fixation.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
