[0048] In the prior art, clothing processing devices introduce cold and dry airflow to improve clothing processing performance. In order to achieve airflow balance in the air duct assembly, it is necessary to open air flow ports to discharge part of the gas in the air duct cavity, which causes hair debris to be entrained and discharged, affecting the user experience.

[0049] To this end, the utility model designs a filter component 4 with an outlet for communicating with the outside of the clothing processing device and a filter element is arranged at the outlet for filtering hair debris. Thus, while the functional integration of the filter component 4 is realized, the airflow discharged to the outside from the outlet can be the airflow filtered by the filter element, thus avoiding the discharge of hair debris to the outside from the outlet and affecting the user experience.

[0050] Reference below Figure 1-Figure 8 A filter assembly 4 according to an embodiment of the present invention is described.

[0051] The filter assembly 4 is mainly used for filtering airflow in the clothing processing device. According to the embodiment of the utility model, the filter assembly 4 includes: a housing 41 and a first filter element 43 .

[0052] The outer shell 41 defines a filter chamber 401, and the filter chamber 401 forms a part of the internal gas channel of the clothing processing device. There are two paths for the flow direction of the air flow inside the clothing processing device, one is a circulating air drying path, and the other is a cold dry air flow in and out path. The filter chamber 401 has an inlet 4111, a first outlet 4121, and a second outlet 4131. The inlet 4111 and the second outlet 4131 are used to communicate with the clothing processing chamber 201 of the clothing processing device, and the first outlet 4121 is used to communicate with the outside of the clothing processing device, that is, part of the airflow entering the filter chamber 401 from the clothing processing chamber 201 of the clothing processing device is diverted at the filter component 4, of which part flows out of the filter chamber 401 through the second outlet 4131 and returns to the clothing processing chamber 201, thereby realizing the recycling of part of the airflow, and the rest flows out of the filter chamber 401 through the first outlet 4121 and is discharged to the outside of the clothing processing device, so as to achieve the balance of the airflow flow inside the clothing processing device.

[0053] The first filter element 43 is disposed at the first outlet 4121. The first filter element 43 can filter the airflow discharged from the first outlet 4121 to the outside of the clothing processing device at the first outlet 4121, and the hair debris and the like entrained in the airflow are fully filtered by the first filter element 43, and the hair debris content in the airflow discharged from the first outlet 4121 is greatly reduced, thereby avoiding the hair debris discharged from the outlet to the outside to affect the user experience.

[0054] Furthermore, by arranging the first outlet 4121 and the first filter element 43 in the filter assembly 4 , the filter assembly 4 is integrated with both the filtering function and the airflow diversion function, thereby realizing the functional integration of the filter assembly 4 .

[0055] According to the filter assembly 4 of the embodiment of the utility model, the filter assembly 4 has stronger functionality, and the airflow discharged to the outside of the external clothes processing device is filtered, thereby improving the user experience.

[0056] Reference Figure 1-Figure 5The housing 41 has a first side wall 412 and the first side wall 412 is located at one end of the housing 41 along a first direction. Figure 1 , Figure 3 and Figure 5 As shown in AB, the first side wall 412 is provided with a first outlet 4121 , that is, the first outlet 4121 is provided on the first side wall 412 .

[0057] The first filter element 43 can be moved along the second direction to open or cover the first outlet 4121. Figure 1 , Figure 3 and Figure 5 as shown in the CD.

[0058] In some embodiments, the first direction intersects with the second direction and both are perpendicular to the height direction of the filter assembly 4 to ensure that the projection of the first filter element 43 covers the first outlet 4121 .

[0059] In some embodiments, the first direction corresponds to the length direction of the outer shell 41 of the filter component 4, the second direction corresponds to the width direction of the outer shell 41 of the filter component 4, and the first direction is perpendicular to the second direction. The first side wall 412 extends along the width direction and the height direction of the outer shell 41 of the filter component 4. The first filter element 43 moves along the second direction parallel to the width direction of the outer shell 41 of the filter component 4 and can move from the outside to the inside to a position parallel to the first side wall 412, thereby covering the first outlet 4121 provided on the first side wall 412.

[0060] Furthermore, during the movement of the first filter element 43 , the upper and lower walls of the housing 41 and the first side wall 412 can limit and guide the movement of the first filter element 43 , thereby ensuring the stability of the movement of the first filter element 43 .

[0061] Further, refer to Figure 1-Figure 5 The shell 41 also has a second side wall 413, and the second side wall 413 is located at one end of the shell 41 along the second direction. The second side wall 413 extends along the length direction and the height direction of the shell 41 of the filter component 4. The second side wall 413 is provided with an installation port 4132 connected to the filter cavity 401 at a position close to the first side wall 412, and the first filter element 43 is suitable for being inserted into the filter cavity 401 from the installation port 4132.

[0062] On the one hand, the installation port 4132 can connect the inside and outside of the filter chamber 401, so that the first filter element 43 can move from the outside of the filter chamber 401 to the inside of the filter chamber 401 through the installation port 4132, so that the first filter element 43 is arranged parallel to and overlaps with the first side wall 412 to cover the first outlet 4121 arranged on the first side wall 412. On the other hand, the extension direction of the installation port 4132 is the same as the movement direction of the first filter element 43. During the process of the first filter element 43 moving along the second direction into the filter chamber 401, the installation port 4132 can guide the movement of the first filter element 43 to ensure that the first filter element 43 always moves along the second direction, ensure the stability of the movement of the first filter element 43, and ensure that the first filter element 43 is set at a position close to the first outlet 4121.

[0063] Reference Figure 3-Figure 5 A limiting member 45 is provided in the filter cavity 401, and the limiting member 45 can further guide the movement of the first filter element 43 to ensure that the first filter element 43 moves along the second direction.

[0064] The limiting member 45 defines a limiting cavity 4501 extending along the second direction and arranged opposite to the installation opening 4132. The limiting cavity 4501 is slidably matched with the first filter element 43. After the first filter element 43 enters the filter cavity 401 through the installation opening 4132, it first enters the limiting cavity 4501 defined by the limiting member 45, and then moves into the filter cavity 401 after further limiting and guiding by the limiting cavity 4501, thereby avoiding the first filter element 43 from being offset and tilted in the filter cavity 401, affecting the matching effect between the first filter element 43 and the first outlet 4121, and affecting the filtering effect of the first filter element 43.

[0065] like Figure 1-Figure 5 As shown, one end of the first filter element 43 has a force-applying portion 431, which provides a position for the user to apply force when pulling the first filter element 43, thereby simplifying the difficulty of disassembling and assembling the first filter element 43 and improving the user's experience.

[0066] Among them, when the first filter element 43 is installed in place on the outer shell 41, the force-applying portion 431 closes the installation opening 4132 and is flush with the outer surface of the second side wall 413, so as to avoid the setting of the first filter element 43 affecting the flatness of the exterior of the filter assembly 4, ensure that the overall appearance of the filter assembly 4 is flat and smooth, and facilitate the pulling and moving of the filter assembly 4 as a whole inside the clothing processing device.

[0067] Reference 3- Figure 5In the second direction, the limit member 45 is located between the first outlet 4121 and the installation port 4132. A stop member 46 is provided on the side of the first outlet 4121 away from the limit member 45 for stopping the first filter element 43. During the installation of the first filter element 43, the stop member 46 can stop the first filter element 43 when the first filter element 43 moves to the limit position, thereby ensuring the accuracy of the installation position of the first filter element 43 and avoiding the first filter element 43 being stuck in place and causing difficulty in disassembly of the first filter element 43. During the operation of the clothing processing device, the stop member 46 can limit the first filter element 43 on one side of the second direction of the first filter element 43, thereby ensuring the stability of the setting of the first filter element 43 and avoiding the first filter element 43 colliding with other structures inside the filter assembly 4 under the drive of airflow to cause noise.

[0068] Combination Figure 3-Figure 5 In the illustrated embodiment, the bottom wall of the filter cavity 401 is provided with a limiting protrusion 47 arranged opposite to the first side wall 412, the limiting protrusion 47 extends along the second direction and defines a slide groove 470 between the limiting protrusion 47 and the first side wall 412, the first filter element 43 slidably cooperates with the slide groove 470, and the slide groove 470 defined between the limiting protrusion 47 and the first side wall 412 can guide the movement of the first filter element 43 during the installation of the first filter element 43, thereby avoiding positional deviation of the first filter element 43 during movement, resulting in the first filter element 43 being stuck and making it difficult to disassemble and assemble the first filter element 43, and avoiding collision of the first filter element 43 with other structures during movement, resulting in damage to the filter screen and other structures provided on the first filter assembly 4.

[0069] During the operation of the clothing processing device, the first side wall 412 and the limiting protrusion 47 can limit the first filter element 43 on both sides of the first direction of the first filter element 43 respectively, ensuring the stability of the setting of the first filter element 43 and preventing the first filter element 43 from colliding with other structures inside the filter assembly 4 under the drive of airflow to cause noise.

[0070] As 3- Figure 6 As shown, the limiting protrusion 47 and the first filter element 43 are respectively provided with a limiting protrusion 432 and a limiting groove on one side facing each other. When the first filter element 43 is installed in place on the outer shell 41, the limiting protrusion 432 cooperates with the limiting groove, and the limiting protrusion 47 and the limiting groove can limit the first filter element 43 in the second direction, thereby ensuring the stability of the setting of the first filter element 43 and preventing the first filter element 43 from colliding with other structures inside the filter assembly 4 under the drive of airflow to cause noise.

[0071] Moreover, the limiting force exerted by the limiting protrusion 47 and the limiting groove on the first filter element 43 is relatively small. When the user pulls the first filter element 43 out of the second direction filter chamber 401, a relatively small force can be used to separate the first filter element 43 from the limiting protrusion 47 and the limiting groove, thereby facilitating disassembly and assembly by the user.

[0072] Reference Figure 3-Figure 5 The filter assembly 4 also includes a second filter element 44, which is arranged at the second outlet 4131. The second filter element 44 can filter the hair debris of the airflow flowing back from the filter chamber 401 to the clothing processing chamber 201 at the second outlet 4131, thereby realizing the hair debris removal processing of the clothing processing device and improving the user experience.

[0073] Therefore, the filter assembly 4 integrates the functions of filtering the airflow discharged outside the clothing processing device, filtering the airflow circulating inside the clothing processing device, and diverting the airflow, and has stronger functionality.

[0074] Reference Figure 1-Figure 5 The second outlet 4131 is arranged on the second side wall 413, and the second side wall 413 extends along the length direction and the height direction of the shell 41 of the filter assembly 4. The second filter element 44 can be moved along the first direction to open or cover the second outlet 4131. The second filter element 44 can be moved from the outside to the inside along the first direction parallel to the second side wall 413 to a position parallel to the second side wall 413, and then cover the second outlet 4131 arranged on the second side wall 413. During the movement of the second filter element 44, the upper and lower walls of the shell 41 can limit and guide the movement of the second filter element 44, thereby ensuring the stability of the movement of the second filter element 44.

[0075] In some embodiments, the first filter element 43 and the second filter element 44 can move along a third direction parallel to the height direction of the outer shell 41 of the filter assembly 4, and can also cover the first outlet 4121 or the second outlet 4131. During this process, the side wall of the outer shell 41 can also limit and guide the movement of the first filter element 43 or the second filter element 44 to ensure the stability of the moving process.

[0076] Reference Figure 3 and Figure 5The filter assembly 4 also includes a third filter element 42, and the third filter element 42 is arranged in the filter cavity 401. In the gas flow direction in the filter cavity 401, the third filter element 42 is located downstream of the inlet 4111 and upstream of the first outlet 4121 and the second outlet 4131. That is to say, the third filter element 42 can first filter the airflow upstream of the first filter element 43 arranged at the first outlet 4121 and the second filter element 44 at the second outlet 4131, thereby greatly reducing the hair content reaching the first filter element 43 or the second filter element 44, reducing the cleaning frequency of the first filter element 43 and the second filter element 44, and improving the user experience.

[0077] Furthermore, the airflow discharged outside the clothing treatment device through the first outlet 4121 undergoes secondary filtration through the first filter element 43 and the third filter element 42, and the hair content is greatly reduced. The circulating airflow undergoes secondary treatment through the second filter element 44 and the third filter element 42, and the hair is fully processed, thereby ensuring the effectiveness of the hair removal function of the clothing treatment device.

[0078] The air duct assembly according to the embodiment of the utility model comprises a plurality of filter assemblies 4 according to the above-mentioned embodiment. Figure 1 The air duct assembly also includes: an air duct shell, the air duct shell defines an air duct cavity, the air duct cavity has a first air inlet 31 and a first air outlet 32, the filter assembly 4 is at least partially arranged in the air duct cavity, the inlet 4111 is connected to the first air inlet 31, the first outlet 4121 is connected to the outside of the air duct cavity, the second outlet 4131 is connected to the air duct cavity, the first air inlet 31 and the first air outlet 32 ​​are connected to the clothing processing cavity 201 of the clothing processing device.

[0079] That is to say, the air flow in the clothing processing chamber 201 flows out of the clothing processing chamber 201, enters the air duct chamber through the first air inlet 31, and then enters the filter chamber 401 through the inlet 4111 of the filter assembly 4. The air flow is divided after being filtered by the third filter element 42 in the filter chamber 401, and part of the air flow is filtered by the second filter element 44 at the second outlet 4131 and then returns to the air duct chamber through the second outlet 4131. After being processed in the air duct chamber, it flows out of the air duct chamber through the first air outlet 32 ​​and then enters the clothing processing chamber 201 to participate in the clothing processing in the clothing processing chamber 201. The remaining air flow is filtered by the first filter element 43 at the first outlet 4121 and then discharged from the air duct chamber through the first outlet 4121, and then discharged to the external space of the clothing processing device.

[0080] Further, if Figure 1As shown, the air duct cavity also has an air inlet 33, and the air inlet 33 connects the inside and outside of the air duct cavity, that is, there are two paths for the air flow direction in the air duct cavity, one is a circulating air drying path, and the other is a cold dry air inlet and outlet path. The above-mentioned air inlet 33 and the first outlet 4121 are not limited to an opening structure of a certain shape, and can also be a gap between components, as long as the purpose of connecting the inside and outside of the air duct cavity is met, and no limitation is made here.

[0081] That is to say, part of the airflow is filtered by the second filter element 44 at the second outlet 4131 and then returns to the air duct cavity through the second outlet 4131 again, and converges with the cold and dry airflow that enters the air duct cavity through the air inlet 33 in the air duct cavity. After being processed in the air duct cavity, they flow out of the air duct cavity through the first air outlet 32 ​​and then enter the clothing processing cavity 201 to participate in the clothing processing in the clothing processing cavity 201.

[0082] According to some embodiments of the utility model, the air duct component also includes a heat exchange component, which is arranged in the air duct cavity. Therefore, the hot and humid airflow returning from the clothing processing cavity 201 to the air duct cavity is subjected to cooling and dehumidification treatment by the heat exchange component and then returns to the clothing processing cavity 201, thereby ensuring the temperature and humidity of the airflow entering the clothing processing cavity 201.

[0083] Furthermore, the heat exchange component includes an evaporator and a condenser, and the evaporator and the condenser are arranged in the air duct cavity. In the flow direction of the gas in the air duct cavity from the first air inlet 31 to the first air outlet 32, the evaporator and the condenser are located downstream of the second outlet 4131, that is, the filter component 4 is located upstream of the evaporator and the condenser, so that the airflow can be filtered by the filter component 4 before passing through the evaporator or condenser, avoiding the accumulation of hair debris at the evaporator or condenser, which affects the heat exchange effect.

[0084] Furthermore, the air flow inlet 33 is located upstream of the condenser, so that all air flows entering the clothing processing chamber 201 are dehumidified by the condenser in the heat exchange assembly, thereby ensuring the humidity of the air flows entering the clothing processing chamber 201 .

[0085] The clothes treating apparatus according to the embodiment of the present invention comprises the air duct assembly according to the above embodiment.

[0086] Reference Figure 1 and Figure 2 The clothing processing device also includes a clothing processing drum assembly, which has a clothing processing chamber 201, a second air inlet 21 and a second air outlet 22 connected to the clothing processing chamber 201, wherein the first air outlet 32 ​​is connected to the second air inlet 21, the first air inlet 31 is connected to the second air outlet 22, and the inlet 4111 and the second outlet 4131 are both connected to the clothing processing chamber 201 through the air duct cavity.

[0087] That is to say, the airflow in the clothing processing chamber 201 flows out of the clothing processing chamber 201 through the second air outlet 22, enters the air duct chamber through the first air inlet 31, and then enters the filter chamber 401 through the inlet 4111 of the filter assembly 4. The airflow is filtered by the third filter element 42 in the filter chamber 401 and then diverted. Part of the airflow is filtered by the second filter element 44 at the second outlet 4131 and then returns to the air duct chamber through the second outlet 4131. After being processed in the air duct chamber, it flows out of the air duct chamber through the first air outlet 32, and then enters the clothing processing chamber 201 through the second air inlet 21 to participate in the clothing processing in the clothing processing chamber 201.

[0088] Reference Figure 1 The air duct assembly is arranged above the clothing processing drum assembly, the air duct cavity includes a first installation area and a second installation area 3012 arranged in a horizontal direction, the filter assembly 4 is arranged in the first installation area and the evaporator and the condenser are arranged in the second installation area 3012.

[0089] like Figure 2 As shown, the clothing treatment device also includes a housing 1, and the clothing treatment drum assembly and the air duct assembly are arranged in the housing 1. The housing 1 has an exhaust port 122, and the exhaust port 122 is connected to the first outlet 4121 and the external space of the housing 1, so that the airflow can be discharged from the filter cavity 401 through the first outlet 4121, discharged from the air duct cavity through the opening on the air duct shell, and discharged from the housing 1 through the exhaust port 122. In some embodiments, the filter assembly 4 is detachably arranged in the air duct assembly, and the air duct assembly is provided with an opening that is connected to the outside world for the removal and installation of the filter assembly 4. The outside world here refers to the space outside the air duct assembly. The first outlet 4121 provided on the filter assembly 4 can exhaust to the outside world by using the original opening for the removal and installation of the filter assembly 4, without the need to design an opening on the air duct assembly to connect the first outlet 4121 with the outside world, which further reduces the production design cost.

[0090] In addition, an opening is provided on the casing 1 to connect the opening on the air duct assembly for disassembling and assembling the filter assembly 4 with the outside of the casing 1. The first outlet 4121 can use the opening to exhaust air to the outside of the casing 1. There is no need to provide an additional opening on the casing 1 to connect the first outlet 4121 with the outside world, thereby further reducing the production design cost.

[0091] Combine the following Figure 1-Figure 8 A specific embodiment of a clothes treating apparatus is described.

[0092] The clothes processing device according to the embodiment of the utility model comprises: a housing 1, a clothes processing drum assembly and an air duct assembly.

[0093] The clothes processing drum assembly and the air duct assembly are arranged in the housing 1 , the clothes processing drum assembly defines a clothes processing chamber 201 , and has a second air inlet 21 and a second air outlet 22 communicated with the clothes processing chamber 201 .

[0094] The air duct assembly includes an air duct shell, a filter assembly 4 and a heat exchange assembly. The heat exchange assembly includes an evaporator and a condenser. The air duct shell defines an air duct cavity, and the air duct shell is provided with an air flow inlet 33, a first air inlet 31 and a first air outlet 32. The air flow inlet 33 connects the inside and outside of the air duct cavity, that is, there are two paths for the air flow direction in the air duct cavity, one is a circulating air drying path, and the other is a cold dry air flow inlet and outlet path.

[0095] Among them, the first air outlet 32 ​​is connected with the second air inlet 21, the first air inlet 31 is connected with the second air outlet 22, the air duct cavity includes a first installation area and a second installation area 3012 arranged in a horizontal direction, the filter assembly 4 is arranged in the first installation area and the evaporator and condenser are arranged in the second installation area 3012.

[0096] In the flow direction of the gas in the air duct cavity from the first air inlet 31 to the first air outlet 32, the filter assembly 4 is located upstream of the evaporator and the condenser, so that the airflow can be filtered by the filter assembly 4 before passing through the evaporator or the condenser, thereby avoiding the accumulation of hair debris at the evaporator or the condenser, which affects the heat exchange effect, and the airflow inlet 33 is located upstream of the condenser. Therefore, all the airflow entering the clothing processing chamber 201 is dehumidified by the condenser in the heat exchange assembly, thereby ensuring the humidity of the airflow entering the clothing processing chamber 201.

[0097] The filter assembly 4 includes an outer shell 41, a first filter element 43, a second filter element 44 and a third filter element 42. The outer shell 41 defines a filter chamber 401. The outer shell 41 includes a first side wall 412 and a second side wall 413. An inlet 4111 is provided on the outer shell 41. A first outlet 4121 is provided on the first side wall 412. The first outlet 4121 is connected to the space outside the casing 1. A second outlet 4131 and an installation port 4132 are provided on the second side wall 413.

[0098] The first filter element 43 is movable along the second direction to open or cover the first outlet 4121 . The installation opening 4132 is provided at a position of the second side wall 413 close to the first side wall 412 . The first filter element 43 is suitable for being inserted into the filter cavity 401 through the installation opening 4132 .

[0099] The filter chamber 401 is provided with a limit member 45, which defines a limit chamber 4501 extending along the second direction and arranged opposite to the installation port 4132. The limit chamber 4501 is slidably matched with the first filter element 43. After the first filter element 43 enters the filter chamber 401 through the installation port 4132, it first enters the limit chamber 4501 defined by the limit member 45, and then moves into the filter chamber 401 after further limiting and guiding by the limit chamber 4501, thereby avoiding the first filter element 43 from being offset and tilted in the filter chamber 401, affecting the matching effect between the first filter element 43 and the first outlet 4121, and affecting the filtering effect of the first filter element 43.

[0100] In the second direction, the limiting member 45 is located between the first outlet 4121 and the installation port 4132. A stopper 46 is provided on the side of the first outlet 4121 away from the limiting member 45 for stopping the first filter element 43. The bottom wall of the filter cavity 401 is provided with a limiting protrusion 47 arranged opposite to the first side wall 412. The limiting protrusion 47 extends along the second direction and defines a slide groove 470 between the limiting protrusion 47 and the first side wall 412. The first filter element 43 slides with the slide groove 470. The limiting protrusion 47 and The first filter element 43 is provided with a limiting protrusion 432 and a limiting groove on one side facing each other. When the first filter element 43 is installed in place on the outer shell 41, the limiting protrusion 432 cooperates with the limiting groove. The limiting protrusion 47 and the limiting groove have a small limiting force on the first filter element 43. When the user pulls the first filter element 43 out of the second direction filter cavity 401, a small force can be used to make the first filter element 43 break away from the limiting of the limiting protrusion 47 and the limiting groove, which is convenient for users to disassemble and assemble.

[0101] One end of the first filter element 43 has a force-applying portion 431, which provides a position for the user to apply force when pulling out the first filter element 43, thereby simplifying the difficulty of disassembling and assembling the first filter element 43 and improving the user's experience. When the first filter element 43 is installed in place on the housing 41, the force-applying portion 431 closes the installation opening 4132 and is flush with the outer surface of the second side wall 413, so as to avoid the setting of the first filter element 43 affecting the flatness of the outside of the filter assembly 4, ensure that the overall appearance of the filter assembly 4 is flat and smooth, and facilitate the pulling and moving of the filter assembly 4 as a whole inside the clothing processing device.

[0102] The second filter element 44 is movable along the first direction to open or cover the second outlet 4131. The inlet 4111 and the second outlet 4131 are both connected to the clothing treatment chamber 201 through the air duct cavity. The third filter element 42 is arranged in the filter cavity 401. In the gas flow direction in the filter cavity 401, the third filter element 42 is located downstream of the inlet 4111 and upstream of the first outlet 4121 and the second outlet 4131. The third filter element 42 can first filter the airflow upstream of the first filter element 43 arranged at the first outlet 4121 and the second filter element 44 arranged at the second outlet 4131, so as to reduce the cleaning frequency of the first filter element 43 and the second filter element 44 and improve the user experience.

[0103] The airflow in the clothing treatment chamber 201 flows out of the clothing treatment chamber 201 through the second air outlet 22, enters the air duct chamber through the first air inlet 31, and then enters the filter chamber 401 through the inlet 4111 of the filter assembly 4. The airflow is filtered and processed by the third filter element 42 in the filter chamber 401 and then split. Part of the airflow passes through the second filter element 44 at the second outlet 4131 and then returns to the air duct chamber through the second outlet 4131. In the air duct chamber, it converges with the cold and dry airflow that enters the air duct chamber through the airflow inlet 33. After being processed in the air duct chamber, it flows out of the air duct chamber through the first air outlet 32, and then enters the clothing treatment chamber 201 through the second air inlet 21 to participate in the clothing treatment in the clothing treatment chamber 201. The remaining airflow passes through the first filter element 43 at the first outlet 4121 and then is discharged from the air duct chamber through the first outlet 4121, and then is discharged to the external space of the clothing treatment device.

[0104] A second opening connected to the outside world is also provided on the air duct shell for disassembling and installing the filter assembly 4. A first opening for disassembling and installing the filter assembly 4 is correspondingly provided on the casing 1. The first opening and the second opening are arranged correspondingly, and the first outlet 4121 provided on the filter assembly 4 is arranged correspondingly to the first opening and the second opening. The first outlet 4121 can exhaust air to the outside of the casing 1 using the first opening and the second opening. There is no need to provide an additional opening on the casing 1 and the air duct shell to connect the first outlet 4121 with the outside world, thereby reducing the production design cost.

[0105] Furthermore, in some embodiments, the casing 1 includes a decorative cover, which is arranged at the first opening to cover the first opening, and an exhaust port 122 is provided on the decorative cover to connect the first outlet 4121 and the external space of the casing 1, so that the air flow can be discharged from the filter cavity 401 through the first outlet 4121, discharged from the air duct cavity through the second opening on the air duct shell, and discharged from the casing 1 through the exhaust port 122.
