The other end of the second drying air duct 42 extends toward the loading and unloading port 22 of the drying drum 2. The first plug interface 411 is provided on the first drying air duct 41.

[0064] For example, Figure 1 and Figure 2 As shown, the first drying air duct 41 and the second drying air duct 42 are located on the same side of the drying drum 2. When the drying drum 2 is horizontally arranged, the first drying air duct 41 and the second drying air duct 42 are both located above the drying drum 2. In addition, the extension direction of the first drying air duct 41 intersects with the extension direction of the second drying air duct 42. Further, the extension direction of the first drying air duct 41 is perpendicular to the axial direction of the drying drum 2, and the extension direction of the second drying air duct 42 is parallel to the axial direction of the drying drum 2, that is, the first drying air duct 41 and the second drying air duct 42 are vertically arranged, and the angle between the two is 90°. In this way, the drying air duct occupies less space and the layout is more optimized.

[0065] Preferably, if Figure 1 and Figure 3 As shown, the filter device 3 of the present application includes a housing 33 and a filter assembly installed on the housing 33 , and the filter assembly can move relative to the housing 33 along the length direction of the housing 33 .

[0066] The housing 33 is fixedly installed between the drying air duct and the housing 1, specifically, the housing 33 is fixedly installed between the first drying air duct 41 and the housing 1, and the two ends of the housing 33 are respectively connected with the first plug interface 411 on the first drying air duct 41 and the second plug interface 11 on the housing 1, and a part of the filter assembly extends into the drying air duct through the first plug interface 411, specifically into the first drying air duct 41, and the filter assembly extends to the second plug interface 11. When the filter device needs to be cleaned, it is only necessary to pull out the filter assembly without disassembling the housing 33 of the filter device. The extension direction of the housing 33 and the filter assembly is preferably parallel to the axial direction of the drying drum 2 of the drying device.

[0067] It should be noted that the housing 33 is not mandatory, and those skilled in the art may also cancel the housing 33 according to actual conditions in actual applications.

[0068] Preferably, if Figures 2 to 4As shown, the filter assembly of the present invention includes a first bracket 31 , a second bracket 32 ​​installed on the first bracket 31 , and a filter screen (not shown in the figure) installed on the second bracket 32 ​​.

[0069] Among them, the first bracket 31 is installed on the shell 33 and can move relative to the shell 33 along the length direction of the shell 33. The first bracket 31 and the second bracket 32 ​​are distributed along the length direction of the shell 33. The extension directions of the first bracket 31 and the second bracket 32 ​​are parallel to the axial direction of the drying drum 2 of the washer-dryer. The first bracket 31 extends to the second plug interface 11, and the second bracket 32 ​​and the filter screen pass through the first plug interface 411 and extend into the drying air duct. Specifically, the second bracket 32 ​​and the filter screen pass through the first plug interface 411 and extend into the first drying air duct 41.

[0070] It should be noted that, in actual application, those skilled in the art can make the second bracket 32 ​​extend completely into the first drying air duct 41, or only make the second bracket 32 ​​with the filter installed extend into the first drying air duct 41, etc. Such flexible adjustment and change do not deviate from the principle and scope of the utility model and should be limited within the protection scope of the utility model. Of course, the utility model preferably makes only a part of the second bracket 32 ​​extend into the first drying air duct 41.

[0071] In addition, it should be noted that, in actual application, those skilled in the art can extend the entire filter screen into the first drying air duct 41, or only extend a portion of the filter screen into the first drying air duct 41, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention. Of course, the present invention preferably extends the entire filter screen into the first drying air duct 41.

[0072] In a first preferred embodiment, the second bracket 32 ​​of the present invention is detachably connected to the first bracket 31 .

[0073] When the filter needs to be cleaned, first pull the first bracket 31 out of the box body 1. When the outer end of the second bracket 32 ​​moves to the outside of the box body 1 with the first bracket 31, disassemble the first bracket 31 and the second bracket 32, and then continue to pull the second bracket 32 ​​until the filter is pulled out. In this way, when disassembling the filter device 3, the required lateral space is smaller, disassembly is more convenient, and it is easy to arrange the washer-dryer.

[0074] In the second preferred case, if Figures 4 to 6 As shown, the second bracket 32 ​​of the present invention can move relative to the first bracket 31 along the length direction of the first bracket 31 .

[0075] When the filter needs to be cleaned, first pull the first bracket 31 out of the box body 1. When the outer end of the second bracket 32 ​​moves to the outside of the box body 1 with the first bracket 31, keep the first bracket 31 stationary and pull the second bracket 32 ​​to move along the first bracket 31 until the filter is pulled out. In this way, when disassembling the filter device 3, the required lateral space is smaller, disassembly is more convenient, and it is easy to arrange the washer-dryer.

[0076] Preferably, if Figures 4 to 6 As shown, the first bracket 31 is provided with a first sliding structure 311 and a second sliding structure 312, the first sliding structure 311 and the second sliding structure 312 are spaced apart along the width direction of the first bracket 31, the second bracket 32 ​​is located between the first sliding structure 311 and the second sliding structure 312, and the second bracket 32 ​​is provided with a third sliding structure 321 and a fourth sliding structure 322 which respectively cooperate with the first sliding structure 311 and the second sliding structure 312.

[0077] For example, Figures 4 to 6 As shown, the width direction of the first bracket 31 is the vertical direction, the first sliding structure 311 and the second sliding structure 312 are spaced apart in the vertical direction, the first sliding structure 311 is located above the second sliding structure 312, the first sliding structure 311 and the third sliding structure 321 are slidably matched, and the second sliding structure 312 and the fourth sliding structure 322 are slidably matched. When the second bracket 32 ​​moves relative to the first bracket 31, the third sliding structure 321 slides along the first sliding structure 311, and the fourth sliding structure 322 slides along the second sliding structure 312.

[0078] It should be noted that the utility model does not limit the specific structural forms of the above-mentioned four sliding structures. For example, it can be set as a structure in which a sliding groove cooperates with a sliding rib, or a structure in which a sliding groove cooperates with a slider, or a structure in which a sliding hole cooperates with a sliding column, and so on.

[0079] Preferably, if Figures 4 to 6 As shown, the first sliding structure 311 is a first sliding groove, and the third sliding structure 321 is a first sliding bar, and the first sliding bar is adapted to the first sliding groove.

[0080] Exemplarily, the first slide groove is located at the top of the first bracket 31 and extends along the length direction of the first bracket 31, the first slide bar is located at the top of the second bracket 32 ​​and extends along the length direction of the second bracket 32, and the first slide bar is located in the first slide groove and can slide along the first slide groove.

[0081] It should be noted that, in practical applications, those skilled in the art may also set the first sliding structure 311 as a first sliding bar, and correspondingly, set the third sliding structure 321 as a first sliding groove.

[0082] Preferably, if Figures 4 to 6 As shown, the second sliding structure 312 is a second sliding bar, the fourth sliding structure 322 is a second sliding groove, and the second sliding bar is matched with the second sliding groove.

[0083] Exemplarily, the second sliding bar is located at the bottom of the first bracket 31 and extends along the length direction of the first bracket 31, the second sliding groove is located at the bottom of the second bracket 32 ​​and extends along the length direction of the second bracket 32, and the second sliding bar is located in the second sliding groove and can slide along the second sliding groove.

[0084] It should be noted that, in practical applications, those skilled in the art may also set the second sliding structure 312 as a second sliding groove, and correspondingly, set the fourth sliding structure 322 as a second sliding bar.

[0085] Preferably, if Figure 6 As shown, a first tapered guide portion 3211 is provided at the end of the first sliding bar.

[0086] For example, Figure 6 As shown, the first sliding bar is arranged on the second bracket 32 ​​, and first tapered guide portions 3211 are arranged at both ends of the first sliding bar, so that the first sliding bar can smoothly enter the first sliding groove on the first bracket 31 .

[0087] Preferably, if Figure 5 As shown, a second tapered guide portion 3121 is provided at the end of the second sliding bar.

[0088] For example, Figure 5 As shown, the second sliding bar is arranged on the first bracket 31 , and a second tapered guide portion 3121 is arranged at one end of the second sliding bar away from the second bracket 32 ​​, so that the second sliding bar can smoothly enter the second sliding groove on the second bracket 32 ​​.

[0089] Preferably, if Figures 4 to 6 As shown, the first bracket 31 is provided with a first positioning structure 313, and the second bracket 32 ​​is provided with a second positioning structure 323. The first positioning structure 313 and the second positioning structure 323 are plugged in and out to prevent the second bracket 32 ​​from sliding relative to the first bracket 31, so as to position the second bracket 32 ​​to a set installation position.

[0090] Exemplarily, the first positioning structure 313 is a positioning opening formed on the first bracket 31, and the second positioning structure 323 is a positioning plate arranged on the second bracket 32. After the filter is cleaned, the second bracket 32 ​​is slid to the set installation position. At this time, the positioning plate on the second bracket 32 ​​can be inserted into the positioning opening on the first bracket 31, so that the second bracket 32 ​​can neither move forward nor backward. In this way, after the second bracket 32 ​​is inserted into the first drying air duct 41, it can ensure that the filter is in the set installation position, thereby ensuring the filtering effect of the filtering device.

[0091] It should be noted that the first positioning structure 313 and the second positioning structure 323 are not limited to the structural form of the positioning port and the positioning plate introduced above. For example, they can also be set as a structure in which a positioning groove cooperates with a positioning plate, or a structure in which a positioning port cooperates with a positioning column, etc.

[0092] Preferably, if Figures 4 to 6 As shown, the first bracket 31 is provided with a first limiting structure 314, and the second bracket 32 ​​is provided with a second limiting structure 324. The first limiting structure 314 and the second limiting structure 324 are abutted against each other to prevent the second bracket 32 ​​from moving relative to the first bracket 31 toward the outer end of the first bracket 31 (from Figure 4 and Figure 5 The left end of the first bracket 31 (as viewed from above) slides to prevent the second bracket 32 ​​from sliding out of the first bracket 31, and the outer end of the first bracket 31 is the end of the first bracket 31 away from the filter screen.

[0093] The first limiting structure 314 cooperates with the second limiting structure 324 to only prevent the second bracket 32 ​​from sliding toward the outer end of the first bracket 31 , but does not prevent the second bracket 32 ​​from sliding toward the inner end of the first bracket 31 .

[0094] It should be noted that the utility model does not limit the specific structural form of the first limiting structure 314 and the second limiting structure 324. For example, it can be set as a structure in which two limiting plates cooperate with each other, or set as a structure in which two limiting blocks cooperate with each other, or set as a structure in which a limiting plate and a limiting block cooperate with each other, and so on.

[0095] Preferably, if Figures 4 to 6 As shown, the first limiting structure 314 is a limiting groove formed on the first bracket 31, the limiting groove penetrates the first bracket 31 along the thickness direction of the first bracket 31, and the limiting groove extends along the length direction of the first bracket 31.
