[0037] This application provides a lint collection device and a washing machine to solve the problem that lint on the load of existing washing machines will block the air duct during the drying process, affecting the drying efficiency of the washing machine and causing energy waste. The following will be described in conjunction with the accompanying drawings.

[0038] The lint collection device 1 provided in this application embodiment is suitable for washing machines. Please refer to [link / reference]. Figures 1 to 2 The washing machine includes a drum 4, a door seal 3, and an air duct. The air duct includes an air inlet section 2 located at the front end of the drum 4 and passing through the door seal 3. The air inlet section 2 forms an air inlet channel 21. The lint collection device 1 includes a box 11 and a filter assembly 12. The box 11 has opposing air inlets 111 and air outlets 113, and a guide channel 112 connecting the air inlets 111 and the air outlets 113. One end of the box 11 with the air inlet 111 is inserted into the air inlet channel 21, and the air outlet 113 faces the drum 4. One end of the filter assembly 12 is attached to the air inlet 111, and the other end extends into the guide channel 112. The filter assembly 12 is used to filter the airflow flowing through the guide channel 112.

[0039] The lint collection device 1 provided in this embodiment has a housing 11 inserted into the air inlet section 2 of the air duct, and air is discharged into the cylinder 4 through the air outlet 113 of the housing 11. A filter assembly 12 is provided inside the housing 11 to filter the flowing air, thereby filtering out impurities such as lint from the air and preventing lint from accumulating in other parts of the air duct and clogging it. This filter assembly 12 is directly connected to the housing 11, has a simple structure, and is easy to disassemble, clean, and maintain.

[0040] Optionally, the door seal 3 is provided with a dispensing port; please refer to [reference needed]. Figure 4 The box body 11 is provided with a handle position 114 at one end near the air outlet 113. The handle position 114 is away from the cylinder body 4 and located inside the inlet. The handle position 114 is used to bear force so that the box body 11 is separated from the air inlet section 2.

[0041] By providing a pry handle 114, the washing machine can easily disassemble the housing 11 for cleaning, as well as the filter assembly 12. This prevents the washing machine from operating with the filter assembly 12 full of lint, ensuring the drying efficiency and cleanliness of the washing machine. The pry handle 114 is located below the door seal 3, near the drum opening 4. Users can remove the housing 11 by forcefully prying the pry handle 114 and pulling downwards. Conversely, after cleaning, the housing 11 can be easily installed by inserting the side with the air inlet 111 into the air inlet channel 21. Disassembly and assembly are simple and convenient.

[0042] The shape of the gripper 114 is not further limited here. In some examples, it can be multiple protrusions spaced apart on the box body 11. In other examples, it can be a bump with a recessed groove underneath to facilitate user gripping.

[0043] Optionally, the air inlet section 2 includes an inner wall that forms the air inlet channel 21, and the inner wall has a recessed groove; the outer side of the box body 11 is provided with a corresponding snap-fit ​​part 115, which snaps into the groove. That is, the box body 11 and the air inlet section 2 can be fixed by snapping the snap-fit ​​part 115 into the groove, and the user can determine that the box body 11 has been installed in place by the "click" sound when the snap-fit ​​part 115 snaps into the groove.

[0044] In some examples, the snap-fit ​​portion 115 can be a buckle. Further, the buckle includes a connecting limiting surface and a guide surface, the limiting surface facing the air outlet 113 and the guide surface facing the air inlet 111. The limiting surface extends horizontally, and the guide surface gradually moves away from the housing 11 at the end closest to the limiting surface. The guide surface is used to guide the housing 11 when it slides in the air inlet channel 21 to prevent interference with the upward sliding of the housing 11. At the same time, when the buckle slides to be opposite the slot, the limiting surface abuts against the slot wall.

[0045] Optionally, the buckle is flexible.

[0046] Optionally, the box body 11 includes a direct flow section and an oblique flow section. The direct flow section is provided with an air inlet 111. The direct flow section is inserted into the air inlet section 2 and extends along the direction of gravity. One end of the oblique flow section is connected to the direct flow section, and the other end is inclined toward the cylinder body 4 and is provided with an air outlet 113.

[0047] By setting a direct flow section, the air resistance within the guide channel 112 is reduced, allowing the gas to pass through the direct flow section with minimal resistance. The oblique flow section guides the gas so that it can be blown towards the cylinder 4 through the outlet 113. It is understood that the direct flow section can be longer than the oblique flow section.

[0048] Optionally, please refer to Figure 3The filter assembly 12 includes a bracket 121 and a filter screen 122. One end of the bracket 121 has a lip 1211, and the other end extends into the DC section. The lip 1211 overlaps with the air inlet 111. The bracket 121 has a mounting hole 1213, which is inclined from one side of the DC section to the other side along the direction of gravity. The filter screen 122 is installed in the mounting hole 1213.

[0049] The bracket 121 directly overlaps the air inlet 111 of the housing 11 via the lip 1211. This process is simple, has low manufacturing cost, and is structurally reliable, preventing the bracket 121 from detaching from the housing 11 due to airflow disturbance and ensuring the stability of the bracket 121. Meanwhile, the mounting hole 1213 is located within the DC section, featuring a simple structure without bending. Furthermore, the mounting hole 1213 is inclined from one side of the DC section to the other along the direction of gravity, allowing for a longer filter screen 122, maximizing the filtration area of ​​the filter screen 122 and improving the filtration effect.

[0050] Optionally, please refer to Figure 5 A limiting part 116 is provided at one end of the DC section near the diagonal flow section, and the other end of the bracket 121 is attached to the limiting part 116. By setting the limiting part 116, a support structure is provided for the other end of the bracket 121, further improving the stability of the bracket 121 in the flow guide channel 112.

[0051] In some examples, the limiting part 116 can be a limiting platform, and the other end of the bracket 121 is attached to the limiting platform.

[0052] Optionally, please refer to Figure 6 The mounting holes 1213 include a plurality of holes spaced apart along the length of the bracket 121. A reinforcing rib 1212 is provided between each pair of adjacent mounting holes 1213, and the reinforcing rib 1212 extends along the width direction of the bracket 121. By providing the reinforcing rib 1212, the structural strength of the bracket 121 is improved, and the bracket 121 is prevented from deforming due to excessively high airflow velocity.

[0053] Optionally, the washing machine also includes a sealing ring 13, which is sealed between the housing 11 and the air inlet section 2.

[0054] By setting the sealing ring 13, the sealing effect between the box body 11 and the air inlet section 2 is improved, preventing gas from leaking out from the gap between the box body 11 and the air inlet section 2, thus avoiding air leakage.

[0055] Furthermore, the sealing rings 13 may include multiple rings and be arranged sequentially along the height direction of the housing 11.

[0056] Optionally, a first positioning part is provided on the outer side of the bracket 121, and a second positioning part is provided inside the housing 11. The first positioning part and the second connecting part are engaged. By setting the first positioning part and the second connecting part, positioning reminders are provided for the installation of the bracket 121, thereby improving installation efficiency.

[0057] Optionally, the bracket 121 includes a lip 1211 and connecting plates connected to both sides of the lip 1211. The connecting plates extend along the height direction of the box 11. The bracket 121 also includes a connecting rib. The connecting end is connected between the two connecting plates and is opposite to the lip 1211. The connecting rib is provided with a slot. The inner wall of the box 11 is provided with a corresponding snap-fit ​​protrusion. After the bracket 121 is installed in place, the snap-fit ​​protrusion snaps into the slot.

[0058] This application embodiment also provides a washing machine, which includes a drum 4, a door seal 3, and an air duct. The air duct includes an air inlet section 2 located at the front end of the drum 4 and passing through the door seal 3. The air inlet section 2 forms an air inlet channel 21. The washing machine also includes a lint collection device 1 as described above. The washing machine can be a drum washing machine.

[0059] Optionally, the door seal 3 has a through-hole forming a insertion channel, the air inlet section 2 is inserted into one end of the insertion channel, and the box body 11 is sequentially inserted into the other end of the insertion channel and into the air inlet channel 21; the washing machine also includes a clamp 5, which surrounds the outer periphery of the door seal 3 to fix the door seal 3, the air inlet section 2 and the box body 11.

[0060] By setting clamp 5, the stability of the connection between air inlet section 2, door seal 3 and box 11 is improved, and air leakage is prevented at the connection between door seal 3 and air inlet section 2.

[0061] Optionally, a limiting plate is provided in the insertion channel of the door seal 3. The air inlet section 2 is inserted into the insertion channel and abuts against the limiting plate, indicating that the air inlet section 2 is installed in place. At the same time, the limiting plate improves the sealing performance of the connection between the air inlet section 2 and the door seal 3.

[0062] Optionally, a limiting protrusion is provided on the outer side of the box body 11. When the box body 11 is inserted into the door seal 3 and the air inlet section 2, the limiting protrusion abuts against the edge of the door seal 3 to prevent the box body 11 from moving further upward.

[0063] Optionally, a limiting block is provided on the side of the air inlet section 2 near the box 11. When the box 11 is inserted into the door seal 3 and the air inlet section 2 and is properly inserted, the top of the box 11 abuts against the limiting block to prevent the box 11 from moving further upward.
