[0050] In the prior art, an air outlet is provided on the air duct assembly of the clothing processing equipment to discharge part of the air flow in the air duct cavity, so as to achieve a balance between the air intake and exhaust of the air duct assembly. The location of the air outlet affects the production cost and user experience of the clothing processing equipment.

[0051] To this end, the embodiment of the present application designs a clothing processing device in which the air flow outlet 4121 is opened at the filter device 4. Since the filter device 4 is generally arranged in the high-pressure area of ​​the air duct cavity, it is ensured that the air outlet opened on the filter device 4 that is connected to the inside and outside can exhaust air outward, and the air flow outlet 4121 structure is integrated into the filter device 4, which simplifies the structure of the air duct component and realizes the opening of the air flow outlet 4121 without changing the structure of the air duct component, thereby better utilizing the existing structure to realize the opening of the air flow outlet 4121 and reducing the design and processing costs.

[0052] The following describes a laundry processing apparatus according to an embodiment of the present application with reference to FIG. 1 to FIG. 10 .

[0053] The laundry processing apparatus according to an embodiment of the present application may include: a laundry processing drum assembly, an air duct assembly and a filter device 4 .

[0054] The clothing processing drum assembly has a clothing processing chamber 201, and is provided with a first air inlet 21 and a first air outlet 22 connected to the clothing processing chamber 201. The clothing processing equipment can use the air duct assembly to process the clothes placed in the clothing processing chamber 201, such as drying clothes.

[0055] The air duct assembly defines an air duct cavity and is provided with a second air inlet 31 communicating with the first air outlet 22 and a second air outlet 32 ​​communicating with the first air inlet 21. The second air inlet 31 and the second air outlet 32 ​​are in communication with the air duct cavity. In other words, air within the laundry processing chamber 201 flows out of the laundry processing chamber 201 through the first air outlet 22, then enters the air duct cavity through the second air inlet 31. After being processed within the air duct cavity, it flows out of the air duct cavity through the second air outlet 32, then enters the laundry processing chamber 201 through the first air inlet 21, participating in the laundry processing within the laundry processing chamber 201.

[0056] The clothing processing device also includes a filtering device, which realizes filtering processing of the airflow in the air duct cavity. The clothing processing device also has an air flow inlet 33 connecting the inside and outside of the air duct cavity. The air flow inlet 33 introduces cold and dry airflow from outside the air duct cavity into the air duct cavity. The cold and dry airflow here refers to the hot and humid airflow introduced into the air duct cavity from the clothing processing cavity 201.

[0057] In the air flow circulation inside the clothing processing device, the cold and dry airflow entering the air duct cavity from the air inlet 33 and part of the airflow returning to the air duct cavity from the clothing processing cavity 201 are discharged from the air duct cavity through the second air outlet 32 ​​and enter the clothing processing cavity 201 through the first air inlet 21. In order to achieve a balance between the inlet and outlet airflow of the clothing processing cavity 201 and the air duct cavity, the clothing processing device also has an airflow outlet 4121 connecting the inside and outside of the air duct cavity to discharge part of the airflow returning to the air duct cavity from the clothing processing cavity 201, that is, there are two paths for the air flow direction in the air duct cavity, one is the circulating air drying path, and the other is the cold and dry airflow in and out path.

[0058] Among them, the airflow outlet 4121 is provided on the filter device 4. Since the filter device 4 is generally provided in the high-pressure area of ​​the air duct cavity, it is ensured that the air outlet opening connecting the inside and the outside of the filter device 4 can exhaust air outward. Moreover, the airflow outlet 4121 is structurally integrated with the filter device 4. While retaining the original function of filtering the airflow, the filter device 4 also has the function of diverting the airflow, which is more functional. It simplifies the structure of the air duct assembly and realizes the provision of the airflow outlet 4121 without changing the structure of the air duct assembly. It better utilizes the existing structure to achieve the provision of the airflow outlet 4121, reducing design and processing costs.

[0059] The air flow inlet and air flow outlet are not limited to opening structures of a certain shape, and can also be gaps between components, as long as they meet the purpose of connecting the inside and outside of the air duct cavity, and are not limited here.

[0060] In some embodiments, the filter device 4 is detachably arranged in the air duct assembly, and the air duct assembly is provided with an opening connected to the outside world for the removal and installation of the filter device 4. The outside world here refers to the space outside the air duct assembly. The air flow outlet 4121 provided on the filter device 4 can use the original opening for the disassembly and assembly of the filter device 4 to exhaust to the outside world, without the need to design an additional opening on the air duct assembly to connect the air flow outlet 4121 with the outside world, further reducing the production design cost.

[0061] According to the clothes processing device of the embodiment of the present application, the clothes processing device reduces production costs and improves user experience by arranging the air flow outlet 4121 on the filter device 4.

[0062] As shown in Figures 5, 6 and 9, the clothing processing device also includes: a casing 1, wherein the casing 1 defines a space for accommodating the internal structure of the clothing processing device, and the clothing processing drum assembly and the air duct assembly are both arranged in the casing 1, that is, in the space defined by the casing 1.

[0063] Among them, the casing 1 has an exhaust port 122, which connects the air flow outlet 4121 and the outside world. The outside world here refers to the external space of the casing 1. Through the setting of the exhaust port 122, the air flow is directly discharged into the external environment of the clothing processing device, avoiding the influence of the air flow on the internal structure of the casing 1 and improving the service life of the clothing processing device.

[0064] In some embodiments, the air duct assembly is provided with an opening connected to the outside world, where the outside world refers to the space outside the air duct assembly. The opening is also connected to the air outlet 4121 and the exhaust port 122 opened on the casing 1. The air outlet 4121 provided on the filter device 4 can exhaust air to the external environment of the clothing processing device through the opening and the exhaust port 122.

[0065] In combination with the embodiments shown in Figures 5 to 9, the casing 1 includes: a shell body, the shell body has a first opening 111, the first opening 111 is connected to the air duct cavity, the filter device 4 can be pushed and pulled in the air duct cavity from the first opening 111, that is, the filter device 4 is detachably arranged in the air duct assembly, and the air duct assembly is provided with an opening connected to the outside of the casing 1 for disassembly and installation of the filter device 4. The casing 1 is also provided with a first opening 111 for disassembly and installation of the filter device 4. The air flow outlet 4121 provided on the filter device 4 can use the above-mentioned opening for disassembly and assembly of the filter device 4 to exhaust to the space outside the casing 1, without the need to design additional openings on the casing 1 and the air duct assembly to connect the air duct cavity and the outside of the casing 1, thereby reducing the production design cost.

[0066] Furthermore, in combination with the embodiments shown in Figures 5 to 9, the casing 1 also includes a first decorative cover 12, which is used to open and close the first opening 111. The first decorative cover 12 is separately arranged from the casing body. The first decorative cover 12 can cover the internal structure opened at the first opening 111 at the first opening 111, ensuring that the appearance of the clothing processing device is complete and beautiful.

[0067] In some embodiments, the first decorative cover 12 is detachably connected to the shell body to open the first opening 111, thereby enabling the disassembly and assembly of the filter device 4. In other embodiments, the first decorative cover 12 is rotatably connected to the shell body to open or cover the first opening 111 by flipping the first decorative cover 12, thereby enabling the disassembly and assembly of the filter device 4.

[0068] In some further embodiments, the first decorative cover 12 is connected to the filter device 4 and moves together with the filter device 4. The filter device 4 can be pushed and pulled in the air duct cavity from the first opening 111. The whole formed by the connection between the filter device 4 and the first decorative cover 12 can move synchronously. Thus, the user can drive the filter device 4 by pushing and pulling the first decorative cover 12, and in the process of pushing and pulling the first decorative cover 12, the opening and covering of the first opening 111 and the disassembly and assembly of the filter device 4 can be realized synchronously, which is more convenient for user operation.

[0069] Further, as shown in Figures 7 and 8, the exhaust port 122 is provided on the first decorative cover 12, that is, the air flow outlet 4121 can be opened on the wall of the filter device 4 arranged opposite to or connected to the first decorative cover 12. Since the first decorative cover 12 shields the air flow outlet 4121 on the outside during use, the air flow discharged from the air flow outlet 4121 will be blocked by the first decorative cover 12. Therefore, the exhaust port 122 is provided on the first decorative cover 12, which can ensure that the air flow can be discharged to the outside of the casing 1. The air flow discharged from the filter cavity 401 from the air flow outlet 4121 passes through the exhaust port 122 opened on the first decorative cover 12 at the first decorative cover 12, and is then discharged to the outside of the casing 1.

[0070] 5 , 6 and 9 , the housing 1 includes a front panel 11, and a first opening 111 is provided on the front panel 11. The first decorative cover 12 and the exhaust port 122 provided on the first decorative cover 12 are also provided on the front panel 11, that is, the front surface of the clothing processing device. When the clothing processing device is embedded in a cabinet or arranged at the rear close to the wall, the high-temperature and humid airflow can be discharged through the front opening of the cabinet or the end away from the wall. In the application environment of the clothing processing device, the front side is usually an open space, which is convenient for taking and putting clothes. Therefore, the hot and humid airflow will not be discharged toward the wall or into the cabinet, causing corrosion of the cabinet or wall or even mold growth. The discharged high-temperature and humid airflow will not wet the cavity or cabinet, thereby improving the user experience.

[0071] In some embodiments, referring to Figure 1, the air inlet 33 is opened on the rear side of the casing 1, and the exhaust port 122 and the air inlet 33 are arranged in front of each other, which can prevent the high-temperature and humid airflow from re-entering the air duct cavity through the air inlet 33, and ensure that the airflow introduced by the clothing processing equipment is cold and dry airflow outside the casing 1.

[0072] In combination with the embodiments shown in Figures 5, 6, 9 and 10, the air flow outlet 4121 is arranged at the front end of the filter device 4 and is arranged opposite to the exhaust port 122. At this time, the air flow discharged from the air flow outlet 4121 can be directly discharged from the clothing processing equipment through the exhaust port 122 arranged on the front side of the casing 1, thereby simplifying the structure of the clothing processing equipment.

[0073] Alternatively, the air outlet 4121 may be located at a front position on the top wall, bottom wall, or side wall of the filter device 4, and the air flow may be discharged directly or indirectly from the clothing processing device through the exhaust port 122 provided on the housing 1. The specific location of the air outlet 4121 on the filter device 4 may be designed differently depending on the location of the filter device 4 within the interior space of the housing 1, and is not limited here.

[0074] In combination with the embodiments shown in Figures 5 and 9, the air flow outlet 4121 is arranged on the wall connecting the filter device 4 and the first decorative cover 12. As a result, the air flow discharged from the air duct cavity by the air flow outlet 4121 can be directly discharged through the exhaust port 122 provided on the first decorative cover 12, reducing the distance of the air flow, avoiding the generation of condensation water, and improving the user experience.

[0075] 7 , the first decorative cover 12 defines a cavity 121 with an open opening, suitable for reaching into the cavity 121 from the open opening for gripping. The user can apply force to the filter device 4 through the cavity 121 to facilitate pulling out the filter device 4, thereby improving the user experience.

[0076] As shown in Figure 7, the exhaust port 122 is provided on the cavity wall of the concave cavity 121, and the first decorative cover 12 has a shielding portion 123. The shielding portion 123 is located on the side of the exhaust port 122 away from the filtering device 4 to shield the exhaust port 122. On the one hand, the shielding portion 123 can guide the discharged airflow to prevent the high-temperature and humid airflow from blowing directly to the user, thereby improving the user experience. On the other hand, the shielding portion 123 can shield the exhaust port 122, thereby improving the integrity of the appearance and the aesthetics of the appearance of the clothing processing device. On the other hand, the shielding portion 123 can prevent dust in the environment outside the casing 1 from entering the air duct cavity through the exhaust port 122, thereby improving the service life of the internal structure of the clothing processing device.

[0077] As shown in Figures 7 and 8, the exhaust port 122 includes multiple exhaust ports 122, which are arranged at intervals on the first decorative cover 12 to reduce the size of each exhaust port 122 while ensuring the exhaust flow rate, so as to reduce the probability of dust in the environment outside the casing 1 entering the interior of the casing 1 through the exhaust port 122, thereby improving the service life of the clothing processing equipment.

[0078] 1 , the filter device 4 defines a filter cavity 401, and at least a portion of the filter cavity 401 is located in the air duct cavity to receive the airflow in the air duct cavity, so that at least a portion of the airflow in the air duct cavity can pass through the filter cavity 401. During the filtering process, the hair and impurities carried in the airflow are blocked and filtered by the filter cavity 401, and the impurity content in the airflow downstream of the filter cavity 401 is greatly reduced, thereby increasing the service life of the internal structure of the air duct assembly of the clothing processing equipment and realizing the hair removal treatment of the clothing.

[0079] In some embodiments, the air flow outlet 4121 is provided in the filter device 4 and can connect the filter chamber 401 with the outside world. The outside world here refers to the space outside the air duct assembly. That is to say, the air flow outlet 4121 connects the filter chamber 401 connected to the air duct chamber with the outside world, thereby realizing the connection between the air duct chamber and the outside world, so that part of the air flow returning to the air duct chamber from the clothing processing chamber 201 can be directly discharged to the outside world.

[0080] In other embodiments, the air flow outlet 4121 is not connected to the filter chamber 401. At this time, the air flow entering the air duct chamber from the second air inlet 31 is diverted upstream or downstream of the filter chamber 401. When the air flow is diverted by part of the structure of the filter device 4 upstream of the filter chamber 401, part of the air flow enters the filter chamber 401 through the inlet of the filter chamber 401, and flows to the downstream of the filter device 4 after being filtered by the filter chamber 401. The remaining part of the air flow is discharged from the air duct chamber through the air flow outlet 4121 opened on the filter device 4. When the air flow is diverted by part of the structure of the filter device 4 downstream of the filter device 4, part of the air flow discharged from the outlet of the filter chamber 401 is discharged from the air duct chamber through the air flow outlet 4121 opened on the filter device 4, and the remaining part of the air flow continues to flow downstream of the air duct chamber.

[0081] In some embodiments, the filter device 4 itself defines an exhaust channel. In other embodiments, the filter device 4 defines an exhaust channel between the filter device 4 and the inner wall of the air duct cavity. The exhaust channel is independent of the filter cavity 401 and communicates with the airflow outlet 4121. In some embodiments, the inlet of the filter cavity 401 and the inlet of the exhaust channel are respectively communicated with the second air inlet 31, or the inlet of the exhaust channel is communicated with the downstream of the filter cavity 401 in the air duct cavity.

[0082] The filter chamber 401 has a third air inlet 4111 and a third air outlet 4131. The third air inlet 4111 is connected to the second air inlet 31 and the filter chamber 401, and the third air outlet 4131 is connected to the air duct chamber and the filter chamber 401. That is to say, the airflow entering the air duct chamber from the second air inlet 31 will enter the filter chamber 401 through the third air inlet 4111, and after being filtered in the filter chamber 401, it will be discharged from the filter chamber 401 through the third air outlet 4131 and enter the downstream of the filter device 4 in the air duct chamber. After further processing at the downstream of the filter device 4, it will flow out of the air duct chamber through the second air outlet 32. The structure downstream of the filter device 4 in the air duct chamber does not need to come into contact with the airflow with hair debris, thereby improving its service life. The airflow then enters the clothing processing chamber 201 through the first air inlet 21, and participates in the clothing processing in the clothing processing chamber 201. The airflow can take away some hair debris in the process of passing through the clothing, thereby realizing hair removal processing of the clothing.

[0083] 4 , the filter device 4 includes: an outer shell 41 and a first filter 42. The outer shell 41 defines a filter chamber 401. A third air inlet 4111 and a third air outlet 4131 are provided on the outer shell 41. The first filter 42 is provided in the filter chamber 401. In the flow direction of the gas in the air duct chamber from the second air inlet to the second air outlet, the third air inlet 4111 is located upstream of the first filter 42, and the third air outlet 4131 is located downstream of the first filter 42. Thus, the airflow is filtered by the first filter 42 and then flows out of the filter chamber 401 through the third air outlet 4131 for the next treatment, thereby improving the service life of the downstream structure of the filter device 4.

[0084] In some embodiments, the air flow outlet 4121 is connected to the filter cavity 401, and the air flow outlet 4121 is located downstream of the first filter 42. At this time, the air flow is filtered by the first filter 42 and then discharged to the outside of the casing 1 or the outside of the air duct cavity through the air flow outlet 4121, avoiding the discharge of hair debris through the exhaust port 122, the blockage of the exhaust port 122 or the flying of hair debris outside the casing 1, thereby improving the user experience.

[0085] In other embodiments, the air flow outlet 4121 is located upstream of the first filter 42 to utilize the exhaust air flow to discharge some of the debris.

[0086] In some further embodiments, the air flow outlet 4121 is not connected to the filter chamber 401. At this time, the air flow entering the air duct chamber from the second air inlet 31 is diverted upstream or downstream of the filter chamber 401. When the air flow is diverted by part of the structure of the filter device 4 upstream of the filter chamber 401, part of the air flow enters the filter chamber 401 through the inlet of the filter chamber 401, is filtered by the filter chamber 401, and then flows to the downstream of the filter device 4. The remaining air flow is discharged from the air duct chamber through the air flow outlet 4121 opened on the filter device 4. When the air flow is diverted by part of the structure of the filter device 4 downstream of the filter device 4, part of the air flow discharged from the outlet of the filter chamber 401 is discharged from the air duct chamber through the air flow outlet 4121 opened on the filter device 4, and the remaining air flow continues to flow downstream of the air duct chamber.

[0087] In some embodiments, the filter device 4 itself defines an exhaust channel. In other embodiments, the filter device 4 defines an exhaust channel between the filter device 4 and the inner wall of the air duct cavity. The exhaust channel is independent of the filter cavity 401 and communicates with the airflow outlet 4121. In some embodiments, the inlet of the filter cavity 401 and the inlet of the exhaust channel are respectively communicated with the second air inlet 31, or the inlet of the exhaust channel is communicated with the downstream of the filter cavity 401 in the air duct cavity.

[0088] In some embodiments, the outer shell 41 includes a bottom shell 416 having an upper opening and an upper cover 417 that closes the upper opening of the bottom shell 416. The upper cover 417 is detachably provided on the bottom shell 416, and the user can install the first filter 42 and other structures in the filter chamber 401 through the upper opening of the bottom shell 416.

[0089] As shown in Figure 4, the first filter screen 42 forms an arc structure and separates the filter cavity 401 into a first chamber 4011 and a second chamber 4012, so as to take advantage of the larger area of ​​the arc structure to enable the airflow to fully contact the first filter screen 42, and the first chamber 4011 can provide space for the storage of hair debris to prevent hair debris from accumulating in the pipeline.

[0090] Among them, the first chamber 4011 is upstream of the first filter 42 in the filter chamber 401, and the second chamber 4012 is downstream of the first filter 42 in the filter chamber 401. In some embodiments, the air flow outlet 4121 is connected to the filter chamber 401, and the air flow outlet 4121 is arranged in the second chamber 4012. At this time, the air flow is filtered by the first filter 42 and then discharged to the outside of the casing 1 through the air flow outlet 4121, avoiding the discharge of hair debris through the exhaust port 122, the blockage of the exhaust port 122 or the flying of hair debris outside the casing 1, thereby improving the user experience.

[0091] In some other embodiments, the air outlet 4121 is disposed in the first chamber 4011 to discharge part of the lint by utilizing the exhaust air flow.

[0092] On the basis of the first filter 42, in order to further ensure the blocking and filtering effect of the filter device 4 on hair debris, and to prevent hair debris from entering the air duct cavity downstream of the filter device 4 under the influence of the air flow, the filter device 4 also includes: a second filter screen, and the second filter screen is arranged between the first filter screen 42 and the third air outlet 4131, or at the third air outlet 4131, to further filter the hair debris in the air flow.

[0093] In some embodiments, the filter device 4 may further include a third filter screen, which is disposed at the air flow outlet 4121 to reduce debris in the exhaust air flow.

[0094] According to some embodiments of the present application, the clothing processing device also includes a heat exchange component, which is arranged in the air duct cavity. The hot and humid air flow returning from the clothing processing cavity 201 to the air duct cavity is cooled and dehumidified by the heat exchange component and then returns to the clothing processing cavity 201, thereby ensuring the temperature and humidity of the air flow entering the clothing processing cavity 201.

[0095] Furthermore, the heat exchange assembly includes an evaporator and a condenser, which are disposed within the air duct cavity. In the direction of air flow from the second air inlet to the second air outlet within the air duct cavity, the airflow inlet 33 is located upstream of the condenser. As a result, all airflow entering the laundry processing chamber 201 undergoes dehumidification treatment by the condenser within the heat exchange assembly, ensuring the humidity of the airflow entering the laundry processing chamber 201.

[0096] Referring to Figure 1, the air duct assembly is arranged above the clothing processing drum assembly and the air duct cavity includes a first installation area and a second installation area 3012 arranged in the horizontal direction. The filter device 4 is arranged in the first installation area and the heat exchange assembly is arranged in the second installation area 3012. Thus, the airflow in the air duct assembly can flow smoothly in the horizontal direction, and the airflow passing through the second installation area 3012 is evenly distributed, which is beneficial to improving the processing efficiency of the heat exchange assembly in cooling and dehumidifying the airflow. The internal structure of the air duct assembly is more reasonably arranged, which is beneficial to reducing the volume of the air duct assembly and realizing the miniaturization and lightweight of the clothing processing equipment.

[0097] According to some embodiments of the present application, as shown in Figure 1, the clothing processing device also includes: a fan, which is arranged between the second air outlet 32 ​​and the first air inlet 21, and is used to drive the air flow entering the air duct cavity to flow toward the first air inlet 21, providing power for the air flow movement inside the clothing processing device, ensuring that the air flow inlet 33 is a low-pressure environment and the air flow outlet 4121 is a high-pressure environment.

[0098] A specific embodiment of the clothes treating apparatus will be described below with reference to the accompanying drawings.

[0099] 1 to 10 , the laundry processing device according to an embodiment of the present application includes: a housing 1 , a laundry processing drum assembly, an air duct assembly, a filter device 4 , a heat exchange assembly, and a fan.

[0100] The housing 1 defines a space for accommodating the internal structure of the laundry processing device. The laundry processing drum assembly and the air duct assembly are both disposed within the housing 1, i.e., within the space defined by the housing 1. The laundry processing drum assembly has a laundry processing chamber 201, and is provided with a first air inlet 21 and a first air outlet 22 that communicate with the laundry processing chamber 201. The laundry processing device utilizes the air duct assembly and the like to process, for example, clothes drying, the laundry placed in the laundry processing chamber 201.

[0101] The air duct assembly is disposed above the laundry processing drum assembly. It defines an air duct cavity and includes a second air inlet 31 communicating with the first air outlet 22 and a second air outlet 32 ​​communicating with the first air inlet 21. The second air inlet 31 and the second air outlet 32 ​​are both connected to the air duct cavity. In other words, air within the laundry processing chamber 201 flows out of the laundry processing chamber 201 through the first air outlet 22, then enters the air duct cavity through the second air inlet 31. After being processed within the air duct cavity, air flows out of the air duct cavity through the second air outlet 32, then enters the laundry processing chamber 201 through the first air inlet 21, participating in the laundry processing within the laundry processing chamber 201.

[0102] The air duct cavity also has an air inlet 33 that communicates with the exterior of the cavity. The heat exchange assembly includes an evaporator and a condenser, both of which are located within the air duct cavity. In the direction of air flow from the second air inlet to the second air outlet within the air duct cavity, the air inlet 33 is located upstream of the condenser. As a result, all air entering the laundry processing chamber 201 undergoes dehumidification treatment by the condenser within the heat exchange assembly, ensuring the humidity of the air entering the laundry processing chamber 201.

[0103] In the air flow circulation inside the clothing processing device, the cold and dry airflow entering the air duct cavity from the air flow inlet 33 and part of the circulating airflow returning to the air duct cavity from the clothing processing cavity 201 are discharged from the air duct cavity through the second air outlet 32 ​​and enter the clothing processing cavity 201 through the first air inlet 21.

[0104] The air duct cavity includes a first mounting area and a second mounting area 3012 arranged horizontally. A filter device 4 and a heat exchange assembly are installed in the air duct cavity, with the filter device 4 located in the first mounting area and the heat exchange assembly located in the second mounting area 3012. The filter device 4 filters the airflow within the air duct cavity, while the heat exchange assembly cools and dehumidifies the airflow within the air duct cavity. The air duct assembly also has a third opening 34 located in the first mounting area. The filter device 4 can be pushed and pulled into the first mounting area through the third opening 34.

[0105] The casing 1 includes a front panel 11, which has a first opening 111 connected to the third opening 34, wherein the casing 1 also includes a first decorative cover 12, which is connected to the front end of the filter device 4, and the filter device 4 and the first decorative cover 12 are connected to form a whole that can move synchronously, so that the filter device 4 and the first decorative cover 12 are connected to form a whole that can be pushed and pulled in the first installation area from the relatively arranged first opening 111 and the third opening 34, and the first decorative cover 12 can be used to open and close the first opening 111, so that the integrity of the front panel 11 is better and the appearance of the clothing processing device is more beautiful.

[0106] The filter device 4 defines a filter chamber 401, and the filter chamber 401 has a third air inlet 4111 and a third air outlet 4131. The third air inlet 4111 is connected to the second air inlet 31 and the filter chamber 401, and the third air outlet 4131 connects the air duct chamber and the filter chamber 401. That is to say, part of the airflow entering the air duct chamber from the second air inlet 31 will enter the filter chamber 401 through the third air inlet 4111, and after being filtered in the filter chamber 401, it will be discharged from the filter chamber 401 through the third air outlet 4131 and enter the downstream of the filter device 4 in the air duct chamber. After further processing at the downstream of the filter device 4, it will flow out of the air duct chamber through the second air outlet 32. The structure downstream of the filter device 4 in the air duct chamber does not need to come into contact with the airflow containing hair debris, thereby improving its service life. The airflow then enters the clothing processing chamber 201 through the first air inlet 21, and participates in the clothing processing in the clothing processing chamber 201. The airflow can take away some hair debris in the process of passing through the clothing, thereby realizing hair removal processing of the clothing.

[0107] Filter device 4 is provided with an airflow outlet 4121, which connects the inside and outside of the air duct cavity. Since filter device 4 is located in the high-pressure area of ​​the air duct cavity, airflow outlet 4121 provided on filter device 4 can exhaust air to the outside of the air duct cavity. Furthermore, filter device 4 is located upstream of the heat exchange component. This means that airflow outlet 4121 discharges air upstream of the heat exchange component, eliminating the need for heat exchange component processing. This avoids energy waste in the clothing processing equipment and improves heat exchange efficiency at the heat exchange component.

[0108] Since the air duct assembly is originally provided with a third opening 34 for disassembling and installing the filter device 4 and communicating with the outside of the air duct cavity and the outside of the casing 1, and the casing 1 is also originally provided with a first opening 111 for disassembling and installing the filter device 4 and communicating with the outside of the casing 1, the air flow outlet 4121 is provided on the filter device 4, and can utilize the original first opening 111 and the third opening 34 to communicate with the outside of the casing 1, thereby reducing the design cost.

[0109] The fan is arranged between the second air outlet 32 ​​and the first air inlet 21, and is used to drive the air flow entering the air duct cavity to flow toward the first air inlet 21, providing power for the air flow movement inside the clothing processing equipment, ensuring that the air flow inlet 33 is a low-pressure environment and the air flow outlet 4121 is a high-pressure environment.

[0110] A first opening 111 is provided on the front panel 11 of the housing 1. A first decorative cover 12 is provided at the first opening 111. An exhaust vent 122 is provided on the first decorative cover 12. The exhaust vent 122 connects the air outlet 4121 with the exterior of the housing 1. The exhaust vent 122 is provided on the front side of the clothing processing device. In the application environment of clothing processing devices, the front side is typically an open space. Therefore, the discharged high-temperature and humid air will not wet the cavity or cabinet, thereby improving the user experience.

[0111] The air inlet 33 is opened on the rear side of the casing 1, and the exhaust port 122 and the air inlet 33 are arranged in front of each other, which can prevent the high-temperature and humid air flow from re-entering the air duct cavity through the air inlet 33, ensuring the effect of the clothing processing equipment introducing the cold and dry air flow outside the casing 1.

[0112] The first decorative cover 12 defines a cavity 121 with an open mouth, so that the user can reach into the cavity 121 from the open mouth for gripping. The user can apply force to the filter device 4 through the cavity 121 to facilitate pulling out the filter device 4, thereby improving the user experience.

[0113] The exhaust port 122 is provided on the cavity wall of the concave cavity 121, and the first decorative cover 12 has a shielding portion 123, which is located in front of the exhaust port 122 to shield the exhaust port 122. On the one hand, the shielding portion 123 can guide the exhausted airflow to prevent the high-temperature and humid airflow from blowing directly to the user, thereby improving the user experience. On the other hand, the shielding portion 123 can shield the exhaust port 122, thereby improving the integrity of the appearance and the aesthetics of the appearance of the clothing processing device. On the other hand, the shielding portion 123 can prevent dust in the environment outside the casing 1 from entering the air duct cavity through the exhaust port 122, thereby improving the service life of the internal structure of the clothing processing device.

[0114] The exhaust vents 122 include multiple exhaust vents 122, which are arranged at intervals on the first decorative cover 12 to reduce the size of each exhaust vent 122 while ensuring the exhaust flow rate, so as to reduce the probability of dust in the environment outside the casing 1 entering the interior of the casing 1 through the exhaust vents 122, thereby improving the service life of the clothing processing equipment.

[0115] The filter device 4 comprises a housing 41 and a first filter screen 42. The housing 41 defines a filter chamber 401. The housing 41 includes a bottom shell 416 with an upper opening and an upper cover 417 that seals the upper opening of the bottom shell 416. The upper cover 417 is detachably mounted on the bottom shell 416, allowing the user to install the first filter screen 42 and other components within the filter chamber 401 through the upper opening of the bottom shell 416. A third air inlet 4111 and a third air outlet 4131 are disposed on the housing 41. The first filter screen 42 forms an arc-shaped structure, dividing the filter chamber 401 into a first chamber 4011 and a second chamber 4012. In the airflow direction, the third air inlet 4111 is located upstream of the first filter screen 42, while the third air outlet 4131 is located downstream of the first filter screen 42. As a result, airflow is filtered by the first filter screen 42 before exiting the filter chamber 401 through the third air outlet 4131 for further processing, thereby extending the service life of the downstream components of the filter device 4.

[0116] In some embodiments, the air flow outlet 4121 is connected to the filter chamber 401, and the air flow outlet 4121 is located downstream of the first filter 42. At this time, the air flow is filtered by the first filter 42 and then discharged to the outside through the air flow outlet 4121, avoiding the discharge of hair debris through the exhaust port 122, the blockage of the exhaust port 122 or the flying of hair debris outside the casing 1, thereby improving the user experience.

[0117] In other embodiments, the air flow outlet 4121 is located upstream of the first filter 42 to utilize the exhaust air flow to discharge some of the debris.

[0118] In some further embodiments, the air flow outlet 4121 is not connected to the filter chamber 401. At this time, the air flow entering the air duct chamber from the second air inlet 31 is diverted upstream or downstream of the filter chamber 401. When the air flow is diverted by part of the structure of the filter device 4 upstream of the filter chamber 401, part of the air flow enters the filter chamber 401 through the inlet of the filter chamber 401, and flows to the downstream of the filter device 4 after being filtered by the filter chamber 401. The remaining part of the air flow is discharged from the air duct chamber through the air flow outlet 4121 opened on the filter device 4. When the air flow is diverted by part of the structure of the filter device 4 downstream of the filter device 4, part of the air flow discharged from the outlet of the filter chamber 401 is discharged from the air duct chamber through the air flow outlet 4121 opened on the filter device 4, and the remaining part of the air flow continues to flow downstream of the air duct chamber.

[0119] The wall surface where the filter device 4 is connected to the first decorative cover 12 is provided with a plurality of reinforcing ribs 414 . The plurality of reinforcing ribs 414 are staggered in the horizontal and vertical directions to improve the structural strength of the filter device 4 and prevent the filter device 4 from being damaged or deformed during disassembly and assembly.

[0120] The filter device 4 is provided with a water retaining rib, and the water retaining rib is located above the air flow outlet 4121. Thus, the condensed water formed on the wall above the air flow outlet 4121 is blocked by the water retaining rib and will not reach the air flow outlet 4121 and be driven by the air flow, thereby improving the user experience.

[0121] The front panel 11 also has a second opening, and the clothing processing device also includes: a detergent box, which is push-pullable in the casing 1 from the second opening and is used to put detergent into the clothing processing chamber 201. The front end of the detergent box has a second decorative cover 13 for opening and closing the second opening.
