The first bracket 41 and the second bracket 42 are distributed along the insertion direction, and are distributed along the length direction of the shell 43 as shown in the figure. The first end of the first bracket 41 extends to the second plug interface 11, and the second end of the first bracket 41 is detachably fixedly connected to the first end of the second bracket 42. The second bracket 42 and the filter pass through the second plug interface 11 and the first plug interface 311 in turn and extend into the first drying air duct 31 and are located upstream of the evaporator.

[0094] The filter is used to filter the air flow in the first drying air duct 31 and intercept impurities such as lint carried by the air flow. By providing plug interfaces on the box body 1 and the first drying air duct 31, when the filter device 4 needs to be cleaned, the filter component can be pulled out from the first drying air duct 31 and the box body 1. In addition, by setting the first bracket 41 and the second bracket 42 to be detachably connected, after the first bracket 41 is pulled out, the first bracket 41 and the second bracket 42 are disassembled, and then the second bracket 42 is pulled out, which can reduce the required disassembly space and facilitate user disassembly. It is also convenient to clean the filter on the second bracket 42. In addition, by making the two ends of the shell 43 connected to the first plug interface 311 and the second plug interface 11 respectively, when installing the filter component, it is convenient to smoothly insert the filter component into the first drying air duct 31, and the user experience is better.

[0095] For example, Figure 1 and Figure 2 As shown, the first plug interface 311 is arranged on the side wall of the front panel of the first drying duct 31 facing the box body 1, and the second plug interface 11 is arranged on the front panel of the box body 1. The extension direction of the filter component of the filter device 4 is parallel to the axis of the drum module 2. In this way, the user can pull out the filter component from the front side of the washer-dryer, which is more convenient.

[0096] Preferably, if Figures 10 to 12 As shown, the filtering device 4 of the utility model also includes a locking pin 44, which is installed on the first bracket 41. The locking pin 44 is provided with a first locking structure 441, and the second bracket 42 is provided with a second locking structure 4221. When the locking pin 44 is in the locked position, the first locking structure 441 cooperates with the second locking structure 4221 to lock the second bracket 42 with the first bracket 41. When the locking pin 44 is in the unlocked position, the first locking structure 441 is separated from the second locking structure 4221 so as to disassemble and separate the second bracket 42 from the first bracket 41.

[0097] Exemplarily, a vertically extending accommodating cavity (not shown in the figure) is provided on the first bracket 41, and the top of the accommodating cavity is open. The locking pin 44 is installed in the accommodating cavity and can move up and down in the vertical direction to switch between the locked position and the unlocked position. The first locking structure 441 includes two locking hooks, and the two locking hooks are spaced apart in the vertical direction. The second locking structure 4221 includes two locking holes arranged at the end of the second bracket 42, and the locking holes are adapted to the locking hooks. A reset spring (not shown in the figure) is installed between the bottom of the locking pin 44 and the accommodating cavity. Under the action of the reset spring, the two locking hooks are respectively inserted into the corresponding locking holes to lock the first bracket 41 and the second bracket 42. When the two brackets need to be disassembled, the locking pin 44 is pressed downward to separate the locking hook from the locking hole, so that the first bracket 41 and the second bracket 42 can be disassembled.

[0098] It should be noted that the first locking structure 441 and the second locking structure 4221 are not limited to the structure of the lock hook and the lock hole described above. For example, they can also be set as two opposite lock hooks, etc. Such adjustments and changes to the specific structural forms of the first locking structure 441 and the second locking structure 4221 do not deviate from the principle and scope of the present utility model, and should be limited within the protection scope of the present utility model.

[0099] Preferably, if Fig.10 and Fig.11 As shown, the second bracket 42 includes a first filter frame 421 and a second filter frame 422. The first end of the first filter frame 421 and / or the second filter frame 422 is detachably fixedly connected to the second end of the first bracket 41, and the second end of the first filter frame 421 is pivotally connected to the second end of the second filter frame 422. The filter includes a first filter installed on the first filter frame 421 and a second filter installed on the second filter frame 422. The mesh number of the first filter is greater than the mesh number of the second filter, and the first filter is located downstream of the second filter.

[0100] Among them, the first filter frame 421 and the second filter frame 422 are arranged side by side along the flow direction of the airflow, the first filter frame 421 is located downstream of the second filter frame 422, the second filter and the first filter are arranged in sequence along the flow direction of the airflow, the airflow first flows through the second filter for coarse filtration, and then flows through the first filter for fine filtration, the filtering effect is better, in addition, by pivotally connecting the first filter frame 421 with the second filter frame 422, it is convenient to clean the first filter and the second filter.

[0101] For example, Fig.11 and Fig.12As shown, the second locking structure 4221 is arranged at the first end of the second filter frame 422, and the end face of the first bracket 41 close to the second bracket 42 has a socket (not shown in the figure), the first end of the second filter frame 422 passes through the socket and extends into the first bracket 41, the second end of the first filter frame 421 does not pass through the socket, and the second end of the first filter frame 421 is located on the outside of the first bracket 41, that is, the length of the first filter frame 421 is less than the length of the second filter frame 422.

[0102] It should be noted that, in actual applications, those skilled in the art may also make the first end of the first filter frame 421 detachably fixedly connected to the first bracket 41, or make the first ends of the first filter frame 421 and the second filter frame 422 detachably fixedly connected to the second end of the first bracket 41.

[0103] In addition, it should be noted that, in actual applications, those skilled in the art may also cancel the setting of the outer shell 43, or may also cancel the setting of the first bracket 41. In this case, the second bracket 42 and the filter can be inserted into the drying air duct from the back or top surface of the box body 1. Alternatively, the first bracket 41 and the second bracket 42 may be completely canceled. In this case, the filter can be directly fixed in the drying air duct, etc. These sub-preferred implementations are also within the protection scope of the present utility model.

[0104] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0105] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
