In this way, the drying air duct occupies less space and the layout is more optimized.

[0054] 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 .

[0055] 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 port 411 on the first drying air duct 41 and the second plug port 11 on the housing 1, and the extension direction of the housing 33 and the filter assembly is parallel to the axial direction of the drying drum 2 of the drying device, and a part of the filter assembly extends into the drying air duct through the first plug port 411, specifically into the first drying air duct 41, and the filter assembly extends to the second plug port 11, and 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.

[0056] 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.

[0057] Preferably, if Figures 2 to 4 As 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 ​​.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Preferably, the second bracket 32 ​​of the present invention is detachably connected to the first bracket 31 .

[0062] 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.

[0063] Preferably, if Figures 4 to 7 As shown, the filter device 3 of the utility model also includes a locking pin 34, a first locking structure 341 is provided on the locking pin 34, and a second locking structure 321 is provided on the first bracket 31 and / or the second bracket 32. When the locking pin 34 is in the locking position, the first locking structure 341 cooperates with the second locking structure 321 to lock the second bracket 32 ​​to the first bracket 31. When the locking pin 34 is in the unlocking position, the first locking structure 341 is separated from the second locking structure 321 so that the second bracket 32 ​​can be removed from the first bracket 31.

[0064] The utility model locks the first bracket 31 and the second bracket 32 ​​through the locking pin 34. When the two brackets need to be disassembled, the locking pin 34 can be unlocked.

[0065] It should be noted that the utility model does not limit the specific structural form of the first locking structure 341 and the second locking structure 321. For example, the first locking structure 341 and the second locking structure 321 can be set as a structure in which two lock hooks cooperate with each other, or as a structure in which a lock hook and a lock mouth cooperate with each other, or as a structure in which a lock column and a lock hole cooperate with each other, and so on.

[0066] In addition, it should be noted that a person skilled in the art may set the locking pin 34 as an independent component, and both the first bracket 31 and the second bracket 32 ​​are provided with a second locking structure, such as a locking hole. After the locking hole on the first bracket 31 is aligned with the locking hole on the second bracket 32, the locking pin 34 is inserted into the two locking holes to lock the first bracket 31 and the second bracket 32, and the portion inserted into the locking hole is the first locking structure; alternatively, the locking pin 34 may be installed on the first bracket 31, and the second locking structure may be set on the second bracket 32; alternatively, the locking pin 34 may be installed on the second bracket 32, and the second locking structure may be set on the first bracket 31, and so on.

[0070] Preferably, if Figures 4 to 7 As shown, the first locking structure 341 is a first locking hook, and the second locking structure 321 is a second locking hook matched with the first locking hook.

[0071] For example, Figures 4 to 7As shown, the first accommodating cavity 311 is arranged on the top surface of the first bracket 31, and the first accommodating cavity 311 is arranged in the vertical direction. The top end of the locking pin 34 extends out from the top of the first accommodating cavity 311, that is, the top end of the locking pin 34 is slightly higher than the top surface of the first bracket 31, which is convenient for pressing the locking pin 34 downward. The first locking hook arranged on the locking pin 34 is arranged upward, and the second locking hook arranged on the second bracket 32 ​​is arranged downward. The first locking hook is located below the second locking hook. When the first locking hook and the second locking hook are hooked with each other, the first bracket 31 and the second bracket 32 ​​are locked. When the two brackets need to be disassembled, the locking pin 34 is pressed downward to separate the first locking hook from the second locking hook.

The first limiting structure 313 cooperates with the second limiting structure 342 to prevent the locking pin 34 from rotating relative to the first accommodating cavity 311 .

[0078] The two limiting structures are used to limit the rotation of the locking pin 34 , thereby ensuring that the first locking structure 341 and the second locking structure 321 are reliably matched.

[0079] It should be noted that the utility model does not limit the specific structural form of the first limiting structure 313 and the second limiting structure 342. For example, it can be set as a structure in which a limiting groove cooperates with a limiting rib, or a structure in which a limiting groove cooperates with a limiting block, or a structure in which a limiting hole cooperates with a limiting plate, and so on.

[0080] Preferably, if Figures 5 to 7 As shown, the first limiting structure 313 is a strip-shaped limiting groove, and the second limiting structure 342 is a strip-shaped limiting rib matched with the strip-shaped limiting groove, and the strip-shaped limiting rib is located in the strip-shaped limiting groove.

[0081] For example, Figures 5 to 7 As shown, the strip-shaped limiting groove extends in the vertical direction, the strip-shaped limiting rib extends in the axial direction of the locking pin 34 , and the strip-shaped limiting rib is inserted into the strip-shaped limiting groove to prevent the locking pin 34 from rotating relative to the first accommodating cavity 311 .

[0082] It should be noted that, in practical applications, those skilled in the art may also set the first limiting structure 313 as a strip-shaped limiting rib, and correspondingly set the second limiting structure 342 as a strip-shaped limiting groove.
