[0057] Example 1

[0058] like Figures 1 to 5 As shown, in this embodiment, a drying system is introduced. The drying system includes an air duct 1 and a filter assembly 6 arranged in the air duct 1.

[0059] like Figures 2 to 3As shown, in this embodiment, the filter assembly 6 covers the entire cross-section of the air duct 1, so that the circulating airflow in the air duct 1 completely flows through the filter 601, ensuring the filtering effect on the interior of the air duct 1.

[0060] Specifically, a spray water channel 603 is provided at the upper end of the filter assembly 6 , and both ends of the spray water channel 603 in the length direction respectively pass through matching notches provided on the wall of the air duct 1 , so that the filter assembly 6 is firmly set in the air duct 1 .

[0061] Preferably, in some specific embodiments, the filter assembly 6 is diamond-shaped as a whole, so that the spray water channel 603 in the filter assembly 6 has a certain inclination angle, which can guide the water flow, make the water flow faster, and improve the efficiency of cleaning the filter.

[0062] like Figure 3 As shown, in this embodiment, the filter assembly 6 includes a filter bracket 602 and a filter 601 arranged on the filter bracket 602. The filter 601 is detachably installed in the air duct. The filter bracket 602 is arranged around the filter 601. A spray water path 603 is arranged in the filter bracket 602 located above the filter 601. The spray water path 603 extends along the length direction of the filter assembly 601.

[0063] Specifically, the filter bracket 602 includes a bracket body and a spray water channel cover 606. The bracket body is used to support the filter 601. A groove is provided on the top of the filter bracket 602. The spray water channel cover 606 is buckled in the notch of the water channel groove to form a spray water channel 603 between the bracket body and the water channel cover.

[0064] Preferably, the spray water channel cover 606 and the filter support 602 are connected by cladding to ensure the sealing of the spray water channel 603 and improve the cleaning efficiency of the filter 601.

[0065] like Figure 4 As shown, in this embodiment, a water retaining rib 6034 is provided inside the spray water channel 603, and the water retaining rib 6034 is arranged at different rib positions to form an inlet water channel 6031 and an outlet water channel 6032 that are connected and arranged in parallel. The inlet water channel 6031 and the outlet water channel 6032 both extend along the length direction of the filter assembly 6.

[0066] Preferably, the length of the outlet waterway 6032 extending along the length direction of the filter assembly 6 is greater than or equal to the length of the filter 601, so that the water flows fully through the filter 601, thereby improving the cleaning efficiency of the filter 601.

[0067] Further preferably, the different rib positions of the water retaining ribs 6034 inside the spray water channel 603 also form a drainage water channel 6033 to prevent the spray water channel 603 from being damaged by excessive water flow and water pressure; the inlet water channel 6031 and the drainage water channel 6033 are interconnected through the outlet water channel 6032 and are arranged in parallel; the drainage water channel 6033 extends along the length direction of the filter screen assembly 6, and the inlet water channel 6031 and the drainage water channel 6033 are on the same side of the outlet water channel 6032.

[0068] Furthermore, in this embodiment, the spray water channel 603 also includes a first connecting port 6035 and a second connecting port 6036. The water inlet water channel 6031 is connected to the water outlet water channel 6032 through the first connecting port 6035, and the water discharge water channel 6033 is connected to the water outlet water channel 6032 through the second connecting port 6036; the first connecting port 6035 and the second connecting port 6036 respectively correspond to the middle part of the water outlet water channel 6032 and divide the water outlet water channel 6032 into three sections.

[0069] like Figures 3 to 5 As shown, in this embodiment, a water inlet 604 is provided in the water inlet channel 6031. The water inlet 604 is arranged at the bottom of the spray water channel 603, bends and extends downward, and is connected to the water inlet end to provide water flow for cleaning the filter.

[0070] Preferably, a drain port 605 is provided at one end of the water inlet waterway 6031 away from the water inlet 604. The drain port 605 is arranged at the bottom of the drain waterway 6033 and is connected to the drain channel for draining excess water. The water flows into the drain channel through the drain port 605 and is discharged through the drain channel.

[0071] like Figure 3 As shown, in this embodiment, a first spray port 607 is provided on a side of the outlet waterway 6031 in the spray waterway 603 close to the filter 601 , and the first spray port 607 is provided at a position corresponding to the outlet waterway 6031 and the filter 601 .

[0072] Specifically, there are multiple first spray ports 607, which are arranged directly above the filter 601, corresponding to the side of the filter 601 close to the upstream direction of the air flow direction; the opening area of ​​the water inlet side of the first spray port 607 is larger than the opening area of ​​the water outlet side, which can increase the spraying force of the water flow on the filter 601, and avoid insufficient water pressure of the water flow resulting in poor flushing effect on the filter 601, affecting the user experience.

[0073] Furthermore, multiple first spray ports 607 are arranged along the length direction of the filter assembly 6, and the arrangement density of the first spray ports 607 on the water outlet waterway 6032 on both sides of the first connecting port 6035 and the second connecting port 6036 is greater than or equal to the arrangement density of the first spray ports 607 on the water outlet waterway 6032 between the first connecting port 6035 and the second connecting port 6036. This can control the water pressure and flow rate of water flow for flushing the filter 601, and prevent the first spray ports 607 on the water outlet waterway 6032 on both sides of the first connecting port 6035 and the second connecting port 6036 from being flushed away due to excessive water pressure on both sides of the filter 601, thereby improving the user experience.

[0074] The water flows into the water inlet channel 6031 from the water inlet 604, passes through the first connecting port 6035, reaches the water outlet channel 6032, and fully sprays the filter screen 601 through the first spray port 607 of the water outlet channel 6032; when the water flow is excessive, the excess water flows into the drainage channel 6033 through the second connecting port 6036, and flows out through the drainage port 605 set on the drainage channel 6033, which can avoid damage to the water channel caused by excessive water pressure and increase the service life of the filter screen assembly 6.

[0075] like Figures 3 to 5 As shown, in this embodiment, a support rib 6021 is further provided on the filter bracket 602 for supporting the filter 601. One end of the support rib 6021 is connected to the bottom of the spray water channel 603, and the other end extends along the width direction of the filter assembly 6 to the bottom of the filter assembly 6.

[0076] Specifically, two support ribs 6021 are provided, which correspond to the connection between the bottom of the spray water channel 603 and the first connecting port 6035 and the second connecting port 6036 respectively. The support ribs 6021 divide the filter screen 601 into three groups, so that each group of filter screens 601 corresponds to a section of the water outlet water channel 6032 set above it, thereby enhancing the stability of the filter screen 601. At the same time, the water flow can more fully correspond to the filter screen 601, fully spray the filter screen 601, and improve the self-cleaning effect of the filter screen assembly 6.

[0077] In this embodiment, the spray water channel 603 also includes a second spray port 6061, which is arranged on the spray water channel cover 606 and faces the upstream side of the spray water channel 603 close to the air flow direction, and is used to flush the upper shell of the air duct and fully clean the residual hair in the air duct 1, so that the filter assembly 6 can work more efficiently.

[0078] Specifically, the second spray port 6061 is in the shape of a circular hole and is arranged above the first spray port 607 . There are multiple second spray ports 6061 arranged along the length direction of the filter assembly 6 .

[0079] Preferably, the second spray ports 6061 are arranged at the same intervals along the length direction of the filter screen assembly 6 .

[0080] The water flows into the water inlet channel 6031 from the water inlet, and then reaches the water outlet channel 6032 through the first connecting port 6035. The water flows out from the first spray port 607 first. When the water in the water outlet channel 607 accumulates to a certain height, it is sprayed on the filter 601 on the upstream side of the air flow direction in the air duct 1 through the second spray port 6061. This can clean the hair debris carried in the circulating air on the upstream side of the air flow direction in the air duct 1 of the filter 601 in the air duct 1, as well as the hair debris accumulated on the side of the upper shell of the air duct located inside the air duct 1, thereby avoiding the accumulation of hair debris on the inner wall of the air duct 1 and affecting the filtering effect, thereby improving the cleaning effect of the filter assembly 6.

[0081] like Figure 2 As shown, in this embodiment, a lower outlet 5 communicating with the air duct 1 is provided at the bottom of the air duct lower shell 101 , and the lower outlet 5 is provided below the air inlet 201 .

[0082] Specifically, the lower outlet 5 is provided at the bottom of the vertical air duct 2 for discharging clean sewage and excess water.

[0083] The first spray port 607 and the second spray port 6061 on the spray water channel 603 rinse the filter 601 and the upper shell of the air duct and clean the sewage, which flows to the bottom of the vertical air duct 2 and is discharged through the lower outlet 5; the water in the drainage water channel 6033 flows into the drainage channel through the drainage port 605, flows to the bottom of the vertical air duct 2 through the drainage channel, and is discharged through the lower outlet 5.

[0084] like Figures 1 to 2 As shown, in some specific embodiments, the air duct is composed of a lower duct shell 101 and an upper duct shell. Both the lower duct shell 101 and the upper duct shell are provided with grooves. The lower duct shell 101 and the groove openings on the upper duct shell are relatively engaged with each other to form the air duct.

[0085] Specifically, a groove is provided on the lower shell body 101 of the air duct, and the groove is open on the side, including a first groove 1011 and a second groove 1012; the first groove 1011 is provided directly below the second groove 1012, and a lower drain port 5 is provided on the side of the first groove 1011 away from the second groove 1012 for draining sewage.

[0086] Furthermore, a baffle 1013 supporting the filter assembly 6 is provided between the first groove 1011 and the second groove 1012. The baffle 1013 is located in the middle of the lower shell 101 of the air duct and is used to support and place the filter assembly 6. The two ends of the baffle 1013 in the length direction are respectively connected to the lower shell 101 of the air duct, and one side of the baffle 1013 in the width direction is connected to the lower shell 101 of the air duct, and the other side extends toward the opening direction of the air duct groove and is not connected to the upper shell of the air duct; the width direction of the baffle 1013 is perpendicular to the wall of the lower shell 101 of the air duct connected to the width direction of the baffle 1013, so that the circulating airflow can completely pass through the filter 601 on the filter assembly 6 from the first groove 1011 to reach the second groove 1012.

[0087] Specifically, there are relatively arranged notches on the wall of the air duct 1 on both sides of the opening of the second groove 1012 for mating connection with the filter assembly 6 .

[0088] like Figure 2 As shown, in this embodiment, the air duct 1 is L-shaped and consists of a vertical air duct 2 and a horizontal air duct 3. The connecting bend between the horizontal air duct 3 and the vertical air duct 2 is located in the second groove 1012. The horizontal air duct 3 extends along the side opposite to the opening of the second groove 1012 and is perpendicular to the vertical air duct 2.

[0089] Preferably, the cross section of the air duct 1 at the bend of the horizontal air duct 3 and the vertical air duct 2 is an inverted triangle, which is used to guide the circulating airflow.

[0090] Specifically, an air outlet connected to the second groove 1012 is provided above the horizontal air duct 3 in the second groove 1012. The air outlet 301 is circular, and the axial direction of the air outlet 301 is perpendicular to the extension direction of the opening of the second groove 1012; the air inlet 201 is arranged inside the first groove 1011 and is located on the side wall opposite to the opening of the first groove 1011.

[0091] Preferably, the air inlet 201 is elliptical, and the opening size is half of the side wall area on the side opposite to the opening of the first groove 1011, thereby improving the circulation efficiency of the circulating air in the air duct 1.

[0092] Preferably, the groove of the lower shell 101 of the air duct also includes a drainage groove for draining excess water; a water retaining rib is provided inside the drainage groove, and the water retaining rib 6034 is relatively arranged on the walls on both sides of the drainage groove for controlling the water flow rate and guiding the water flow.

[0093] Specifically, the drain groove is provided on one side of the first groove 1011 and the second groove 1012 , the end of the drain groove close to the air outlet 301 is communicated with the second groove 1012 , and the end of the drain groove away from the air outlet 301 is communicated with the first groove 1011 .

[0094] The structure of the upper shell of the air duct cooperates with the structure of the lower shell 101 of the air duct, and is snap-fitted with the lower shell 101 of the air duct, so that the drainage trough forms a drainage channel, and the first groove 1011 and the second groove 1012 form a vertical air duct 2, which is connected to the horizontal air duct 3 in the second groove 1012.

[0095] The circulating airflow of the drying system enters the vertical air duct 2 from the air inlet 201, passes through the filter assembly 6, and then passes through the horizontal air duct 3, and flows out from the air outlet 301. The circulating airflow continuously repeats the above steps to perform the drying work.

[0096] In this embodiment, a clothes processing device is also disclosed, in which the above-mentioned drying system is installed.

[0097] Example 2

[0098] like Figures 1 to 5 As shown, in this embodiment, a drying system is introduced. The drying system includes an air duct 1 and a filter assembly 6 arranged in the air duct.

[0099] like Figures 2 to 3 As shown, in this embodiment, the filter assembly 6 is arranged in the vertical air duct 2, covering the entire cross-section of the air duct 1, including the cross-section of the air duct 1 at the connection bend between the horizontal air duct 3 and the vertical air duct 2.

[0100] Specifically, in this embodiment, the filter assembly 6 includes a filter bracket 602 and a filter 601 arranged on the filter bracket 602. The filter 601 is arranged on the side of the cross section of the air duct 1 away from the bend of the air duct 1 of the filter assembly 6, facing the upstream of the air flow, so that impurities such as hair debris carried in the circulating air flow can be attached to the filter 601, thereby filtering the circulating air flow; the filter bracket 602 is arranged around the filter 601, and spray water paths 603 are arranged in the filter bracket 602 above, below and on both sides of the filter 601.

[0111] like Figures 1 to 5 As shown, in this embodiment, a drying system is introduced. The drying system is applied to a clothes processing device to dry clothes in the clothes processing device.

[0112] The drying system is communicated with the drum module of the clothes processing device. Specifically, the drum module includes an inner drum for accommodating clothes to be washed and an outer drum coaxially sleeved outside the inner drum. The drying system is communicated with the outer drum of the drum module.

[0113] Specifically, the drying system includes an air duct 1, which is in an inverted L-shape and includes a horizontal air duct 3 and a vertical air duct 2. The horizontal air duct 3 is arranged on the right side above the drum module and extends horizontally from front to back. The vertical air duct 2 is arranged on the rear side of the drum module and extends downward from the rear end of the horizontal air duct 3. The air duct 1 can avoid the area directly above the drum module, so that the overall structure of the drying system is integrated and arranged in the space on both sides above the drum module, and the gap between the cabinet and the drum module can be fully utilized, making the overall layout of the clothes processing device more compact, thereby reducing the overall size of the clothes processing device.

[0114] Furthermore, the air duct 1 is provided with an air inlet 201 and an air outlet 301. The air inlet 201 is arranged on one side of the vertical air duct 2 close to the cylinder module and is connected to the air outlet end of the cylinder module; the air outlet 301 is arranged at the top of the horizontal air duct 3 and is connected to the air inlet end of the cylinder module.

[0115] like Figures 2 to 3 As shown, in this embodiment, the drying system further includes a filter assembly 6 , which includes a filter 601 disposed in the air duct 1 for filtering hair debris entering the air duct 1 .

[0116] Specifically, the filter 601 is a metal filter and is in-mold-molded with the filter bracket 602 to ensure integrity and prevent dirt from adhering to the assembly joints. Furthermore, the filter 601 is prevented from being deformed or detached due to excessive pressure of the spray water, which would affect the cleaning effect of the circulating airflow and thus improve the user experience.

[0117] like Figures 3 to 5 As shown, in this embodiment, the filter assembly 6 also includes a filter bracket 602, and the filter bracket 602 is located on one side of the filter 601 and is provided with a spray water path 603, and the spray water path 603 extends along the length direction of the filter assembly 6; a first spray port 607 and a second spray port 6061 are provided on one side of the spray water path 603, which are used to spray and flush the filter assembly 6 near the upstream side of the air flow in the air duct 1.

[0118] Specifically, the filter bracket 602 includes a bracket body and a spray water channel cover 606. The bracket body is used to support the filter 601. The spray water channel cover 606 and the filter bracket 602 are connected by cladding, and a spray water channel 603 is formed between the bracket body to ensure the sealing of the spray water channel and improve the efficiency of filter cleaning.

[0119] like Figure 4As shown, in this embodiment, a water retaining rib 6034 is provided inside the spray water channel 603, and the water retaining rib 6034 is arranged at different rib positions to form an inlet water channel 6031 and an outlet water channel 6032, which are connected and arranged in parallel. The inlet water channel 6031 and the outlet water channel 6032 both extend along the length direction of the filter mesh assembly 6; the length of the outlet water channel 6032 extending along the length direction of the filter mesh assembly 6 is greater than or equal to the length of the filter mesh 601, so that the water flow can fully pass through the filter mesh 601, thereby improving the cleaning efficiency of the filter mesh 601.

[0120] Specifically, the spray water channel 603 also includes a first connecting port 6035 and a second connecting port 6036. The water inlet water channel 6031 is connected to the water outlet water channel 6032 through the first connecting port 6035, and the water discharge water channel 6033 is connected to the water outlet water channel 6032 through the second connecting port 6036; the first connecting port 6035 and the second connecting port 6036 respectively correspond to the middle part of the water outlet water channel 6032 and divide the water outlet water channel 6032 into three sections.

[0121] like Figures 3 to 5 As shown, in this embodiment, a water inlet 604 is provided in the water inlet waterway 6031, and the water inlet 604 is arranged at the bottom of the spray waterway 603, bends downward and extends, and is connected to the water inlet end to provide water flow for cleaning the filter; a drain port 605 is provided at the end of the water inlet waterway 6031 away from the water inlet 604, and the drain port 605 is arranged at the bottom of the drain waterway 6033, and is connected to the drain channel for draining excess water; the water flows into the drain channel through the drain port 605, and flows to the bottom of the vertical air duct 2 through the drain channel for discharge.

[0122] like Figures 4 to 5 As shown, in this embodiment, a first spray port 607 is provided on a side of the outlet water channel 6032 in the spray water channel 603 close to the filter 601 , and the first spray port 607 is provided at a position corresponding to the outlet water channel 6032 and the filter 601 .

[0123] Specifically, there are multiple first spray ports, which are arranged directly above the filter, corresponding to the side of the filter close to the upstream direction of the air flow direction; the opening area of ​​the water inlet side of the first spray port is larger than the opening area of ​​the water outlet side, which can increase the spraying force of the water flow on the filter, avoid insufficient water pressure of the water flow, resulting in poor flushing effect on the filter, and affecting the user experience.

[0124] Furthermore, multiple first spray ports 607 are arranged along the length direction of the filter assembly 6, and the arrangement density of the first spray ports 607 on the water outlet waterway 6032 on both sides of the first connecting port 6035 and the second connecting port 6036 is greater than or equal to the arrangement density of the first spray ports 607 on the water outlet waterway 6032 between the first connecting port 6035 and the second connecting port 6036. This can control the water pressure and flow rate of water flow for flushing the filter 601, and prevent the first spray ports 607 on the water outlet waterway 6032 on both sides of the first connecting port 6035 and the second connecting port 6036 from being flushed away due to excessive water pressure on both sides of the filter 601, thereby improving the user experience.

[0125] The water flows into the water inlet channel 6031 from the water inlet 604, passes through the first connecting port 6035, reaches the water outlet channel 6032, and fully sprays the filter screen 601 through the first spray port 607 of the water outlet channel 6032; when the water flow is excessive, the excess water flows into the drainage channel 6033 through the second connecting port 6036, and flows out through the drainage port 605 set on the drainage channel 6033, which can avoid damage to the water channel caused by excessive water pressure and increase the service life of the filter screen assembly 6.

[0126] like Figure 3 and 5 As shown, in this embodiment, a support rib 6021 is further provided on the filter bracket 602 for supporting the filter 601. One end of the support rib 6021 is connected to the bottom of the spray water channel 603, and the other end extends along the width direction of the filter assembly 6 to the bottom of the filter assembly 6.

[0127] Specifically, two support ribs 6021 are provided, which correspond to the connection between the bottom of the spray water channel 603 and the first connecting port 6035 and the second connecting port 6036 respectively. The support ribs 6021 divide the filter screen 601 into three groups, so that each group of filter screens 601 corresponds to a section of the water outlet water channel 6032 set above it, thereby enhancing the stability of the filter screen 601. At the same time, the water flow can more fully correspond to the filter screen 601, fully spray the filter screen 601, and improve the self-cleaning effect of the filter screen assembly 6.

[0128] In this embodiment, the spray water channel 603 also includes a second spray port 6061, which is arranged on the spray water channel cover 606 and faces the upstream side of the spray water channel 603 close to the air flow direction, and is used to flush the upper shell of the air duct and fully clean the residual hair in the air duct 1, so that the filter assembly 6 can work more efficiently.

[0129] Specifically, the second spray port 6061 is in the shape of a circular hole and is arranged above the first spray port 607 . There are multiple second spray ports 6061 arranged along the length direction of the filter assembly 6 with the same arrangement intervals.

[0130] Water flows into the water inlet channel from the water inlet, and then reaches the water outlet channel through the first connecting port. The water flows out from the first spray port first. When the water in the water outlet channel accumulates to a certain height, the water is sprayed on the filter screen near the upstream side of the air flow direction in the air duct through the second spray port. This can clean the lint carried in the circulating air on the upstream side of the air flow direction in the air duct of the filter screen in the air duct, as well as the lint accumulated on the side of the upper shell of the air duct inside the air duct, avoiding the influence of filtration effect caused by the accumulation of lint on the inner wall of the air duct, improving the self-cleaning efficiency of the filter screen, and making the filter screen in the drying system clean more thoroughly.

[0131] like Figure 2 As shown, in this embodiment, a lower outlet 5 communicating with the air duct 1 is provided at the bottom of the air duct lower shell 101 , and the lower outlet 5 is provided below the air inlet 201 .

[0132] Specifically, the lower outlet 5 is provided at the bottom of the vertical air duct 2 for discharging clean sewage and excess water.

[0133] The first spray port 607 and the second spray port 6061 on the spray water channel 603 rinse the filter 601 and the upper shell of the air duct and clean the sewage, which flows to the bottom of the vertical air duct 2 and is discharged through the lower outlet 5; the water in the drainage water channel 6033 flows into the drainage channel through the drainage port 605, flows to the bottom of the vertical air duct 2 through the drainage channel, and is discharged through the lower outlet 5.
