Description

Technical Field

[0001] This invention belongs to the field of clothing cleaning, specifically, it relates to a lint filter device, an inner drum, and a clothing processing device. Background Technology

[0002] With social development and technological progress, and the continuous improvement of people's living standards, laundry processing equipment is rapidly becoming popular in various households, bringing convenience to users' laundry. For top-loading impeller laundry processing equipment, large capacity and high dehydration rate are its main development trends.

[0003] To improve washing performance, existing pulsator-type garment washing machines typically incorporate a lint filter on the inner tub. This lint filter includes a return water cover and a filter assembly mounted on it. The return water cover itself forms an upward-extending flow channel, or it works in conjunction with the inner tub to form an upward-extending flow channel. The flow channel connects to the water inlet of the filter assembly. Under centrifugal force, the water in the inner tub flows to the vicinity of the inner wall of the inner tub, and then flows upward along the flow channel into the filter assembly, thereby filtering out lint from the water.

[0004] Currently, the filter assembly has a snap-fit ​​structure at the top and an insert plate at the opposite end. Correspondingly, the return water cover has a slot for the snap-fit ​​structure to engage and a slot for the insert plate to be inserted. In use, the filter assembly is first tilted from top to bottom towards the return water cover, and the insert plate at the bottom of the filter assembly is inserted into the corresponding slot. Then, the top of the filter assembly is rotated around its bottom towards the return water cover, and the snap-fit ​​structure engages in the corresponding slot. Although this allows the filter assembly to be installed on the return water cover, the slot needs to provide freedom of rotation for the filter assembly. This results in a vertical degree of freedom between the insert plate and the slot after the filter assembly is installed. During operation, the filter assembly and the return water cover wobble relative to each other, producing abnormal noise. Furthermore, after prolonged use, the gap between the filter assembly and the return water cover gradually increases, affecting the stability of the filter assembly installation and posing a risk of the filter assembly falling off.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a lint filter device, inner barrel and clothing processing equipment for clothing processing equipment. By setting a support structure with a replacement slot, the filter component can be installed by sliding and rotating relative to the support structure during the installation process. The support structure can provide the filter component with relative rotational freedom while providing stable limiting in the direction perpendicular to the side wall of the support structure, thereby solving the problem of unstable fixing of the existing filter component.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a lint filtering device for clothing processing equipment, comprising: a return water cover plate having a flow channel; a filter assembly, at least partially disposed in the flow channel of the return water cover plate for filtering lint; and a support structure with a protruding surface provided on the flow channel wall, the support structure having a first wall for limiting the position of the filter assembly.

[0008] Furthermore, the support structure is located upstream of the filter assembly;

[0009] Preferably, the flow channel extends vertically, and the top wall of the support structure abuts against the filter assembly.

[0010] Furthermore, multiple support structures are spaced apart within the flow channel, and the first wall of each support structure is connected to the filter assembly.

[0011] Preferably, multiple support structures are arranged at intervals perpendicular to the direction of flow channel extension.

[0012] Furthermore, an installation port is provided on the return water cover, through which the filter assembly is installed into the return water cover; the support structure is spaced a distance from the periphery of the installation port, and the filter assembly is provided with an abutment structure protruding towards the support structure, which abuts against the support structure.

[0013] Preferably, the installation port is opened on the surface of the return water cover plate, the flow channel extends from the bottom end of the return water cover plate to the installation port, and the support structure is located below the installation port;

[0014] Another preferred embodiment includes a plate-shaped protrusion, the extended end of which abuts against the support structure, and the sidewall of the protrusion is connected to the inner sidewall of the return water cover.

[0015] In a further preferred embodiment, the two sides of the protrusion are respectively provided with bent portions that bend and extend away from the return water cover.

[0016] Furthermore, the first wall of the support structure extends perpendicularly to the direction of flow channel extension or extends obliquely in the direction of flow channel extension along the protruding direction.

[0017] Furthermore, the support structure is plate-shaped, and the plate surface of the support structure is parallel to the extension direction of the flow channel;

[0018] Preferably, the second wall at the bottom of the support structure extends upward at an angle along the convex direction.

[0019] Furthermore, the filter assembly and / or return water cover are provided with a limiting structure, and the return water cover and / or filter assembly are provided with a limiting groove corresponding to the limiting structure, and the limiting groove is open.

[0020] Preferably, the cross-section of the limiting structure gradually decreases along the extension direction, and the limiting structure is configured to match the shape of the limiting groove.

[0021] Furthermore, the return water cover is provided with an assembly groove for accommodating the filter assembly, and a limiting structure protrudes from the bottom of the assembly groove, which is formed by the filter assembly being recessed inward.

[0022] Preferably, the limiting structure is located on the outer periphery of the bottom of the assembly groove and is connected to the groove wall.

[0023] An inner tub of a garment processing device is equipped with a lint filter device as described above.

[0024] Preferably, the return water cover plate and the inner tank body cooperate to form a flow channel, and at least part of the support structure is connected to the return water cover plate.

[0025] A garment processing device, employing a lint filter device as described above, or employing an inner drum body as described above.

[0026] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: By setting a support structure, the filter assembly can slide along the support wall while rotating relative to it during installation, thereby forming a flexible eccentric rotation installation method. This avoids interference between the return water cover and the filter assembly, improving installation flexibility while eliminating the need for the support structure to reserve a degree of freedom perpendicular to the opposite side wall of the support structure. This ensures a stable connection between the filter assembly and the return water cover, preventing relative shaking and noise, and improving the stability and service life of the lint filter.

[0027] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

[0041] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] like Figures 1 to 10 As shown in the embodiment of the present invention, a lint filtering device for a garment processing equipment is introduced, including a return water cover plate 2, which forms a flow channel 201; a filter assembly 3, which is at least partially disposed in the flow channel 201 of the return water cover plate 2 for filtering lint; and a support structure 210 with a protruding surface is provided on the wall of the flow channel 201, the support structure 210 having a first wall 211 for limiting the position of the filter assembly 3.

[0046] With the above configuration, by setting the support structure 210, the filter assembly 3 can slide along the support wall while rotating relative to the first wall 211 during installation, thereby forming a flexible eccentric rotation installation method. This avoids interference between the return water cover 2 and the filter assembly 3, improving installation flexibility. It also eliminates the need to reserve a degree of freedom perpendicular to the opposite side wall of the support structure 210, ensuring a stable connection between the filter assembly 3 and the return water cover 2, preventing relative shaking and noise, and improving the stability and service life of the lint filter.

[0047] In one embodiment of the present invention, the filter assembly 3 extends into the flow channel 201 along a direction perpendicular to the extension direction of the flow channel 201, and the orientation of the first wall 211 of the support structure 210 is perpendicular to the extension direction of the flow channel 201.

[0048] In an embodiment of the present invention, one end of the filter assembly 3 is engaged with the corresponding slot 230 on the return water cover plate 2 via a snap-fit ​​structure 350, and the other end abuts against the first wall 211 of the support structure 210, so as to stably fix the filter assembly 3 on the return water cover plate 2.

[0049] In an embodiment of the present invention, the support structure 210 is located upstream of the filter assembly 3, such that the support direction of the support structure 210 for the filter assembly 3 is parallel to the extension direction of the flow channel 201. By placing the support structure 210 upstream of the filter assembly 3, it can provide a stable support force for the filter assembly 3 before the water flow impacts the filter assembly 3. When water just flows into the flow channel 201, the support structure 210 can withstand part of the impact force of the water flow, preventing the water hammer effect from causing the filter assembly 3 and the return water cover plate 2 to shake relative to each other, thereby improving the service life of the filter assembly 3.

[0050] In an embodiment of the present invention, the flow channel 201 extends vertically, and the top wall of the support structure 210 abuts against the filter assembly 3; so that the filter assembly 3 abuts against the support structure 210 by its own weight, thereby further improving the stability of the assembly of the filter assembly 3 and the support structure 210.

[0051] In one embodiment of the present invention, the support structure 210 extends continuously along the circumference of the flow channel 201; preferably, the support structure 210 is formed by connecting the ends.

[0052] In embodiments of the present invention, multiple support structures 210 are spaced apart within the flow channel 201, and the first wall 211 of each support structure 210 is connected to the filter assembly 3. Preferably, multiple support structures 210 are arranged at intervals perpendicular to the extension direction of the flow channel 201. This provides multi-point support for the filter assembly 3, effectively dispersing the impact force and vibration energy of the water flow, and preventing damage to the stress-concentrated part of the filter assembly 3 due to excessive local stress. At the same time, the circumferential distribution of the support structures 210 can divide the flow channel 201 into multiple independent filtration zones, preventing the accumulation of lint in local areas and ensuring smooth water flow within the flow channel 201.

[0053] In an embodiment of the present invention, the return water cover plate 2 has an integrated flow channel 201 inside, and one end of the support structure 210 is connected to one side wall of the return water cover plate 2; preferably, the other end of the support structure 210 is connected to the other side wall of the return water cover plate 2 to form a support grid, which improves the stability of the support for the filter device and allows the support structure 210 to perform initial filtration of water, thereby improving the filtration effect.

[0054] In an embodiment of the present invention, the return water cover 2 and the inner tub 1 of the clothing processing equipment cooperate to form a flow channel 201, and at least part of the support structure 210 is connected to the return water cover 2.

[0055] In one embodiment of the present invention, part of the support structure 210 is connected to the return water cover plate 2, and another part of the support structure 210 is connected to the inner barrel body 1 of the inner barrel; preferably, the support structure 210 on the inner barrel body 1 is a support press formed by stamping the inner barrel body 1.

[0056] In another preferred embodiment of the present invention, the support structures 210 are all disposed on the return water cover plate 2.

[0057] In an embodiment of the present invention, the extended end face of the support structure 210 is connected to the inner barrel body.

[0058] In the embodiments of the present invention, the extended end of the support structure 210 is spaced apart from the inner barrel body by a certain distance; so that the support structure 210 can stably support the filter assembly 3, while avoiding the situation where the extension length of the support structure 210 in actual production is greater than the original design length due to factors such as process errors, which would prevent the return water cover 2 from being unable to be installed due to mutual interference between the support structure 210 and the inner barrel body 1, thereby reducing the scrap rate.

[0059] In an embodiment of the present invention, an installation port 220 is provided on the return water cover plate 2, and the filter assembly 3 is installed into the return water cover plate 2 through the installation port 220; the support structure 210 is provided at a distance from the peripheral side of the installation port 220, and the filter assembly 3 is provided with an abutment structure 310 protruding towards the support structure 210, and the abutment structure 310 abuts against the support structure 210.

[0060] With the above settings, the installation port 220 on the return water cover 2 ensures that the filter assembly 3 can be smoothly inserted and fixed, while preventing water leakage. At the same time, by setting a distance between the support structure 210 and the installation port 220, the filter assembly 3 needs to extend into the flow channel 201 to contact the support structure 210, and the wall of the flow channel 201 can limit the contact structure 310, improving the stability of the return water cover 2 in limiting the filter assembly 3, thereby further reducing the abnormal noise emitted by the lint filter and extending its service life.

[0061] In an embodiment of the present invention, the mounting port 220 is formed on the surface of the return water cover plate 2, the flow channel 201 extends from the bottom end of the return water cover plate 2 to the mounting port 220, and the support structure 210 is located below the mounting port 220.

[0062] In an embodiment of the present invention, the abutting structure 310 includes a plate-shaped protrusion 311, the extended end of which abuts against the support structure 210, and the sidewall of the protrusion 311 is connected to the inner sidewall of the return water cover plate 2. By providing the protrusion 311, the plate-shaped protrusion 311 can not only improve the stability of the installation through the support structure 210 and the inner sidewall of the return water cover plate 2, but also has little impact on the flow area of ​​the flow channel 201, so that the water in the flow channel 201 can flow smoothly into the filter assembly 3.

[0063] In an embodiment of the present invention, the protruding portion 311 is provided with bent portions 312 on both sides, which bend and extend away from the return water cover plate 2; in order to improve the structural strength of the protruding portion 311 and prevent the protruding portion 311 from deforming after long-term use.

[0064] In an embodiment of the present invention, the inner sidewall of the return water cover plate 2 is spaced apart from the inner barrel 1 to form a flow channel 201. The left and right sides and the top edge of the return water cover plate 2 are respectively connected to connecting walls 241 that bend and extend towards the inner barrel 1, and are connected to the inner barrel 1 through the connecting walls 241. The bottom edge of the return water cover plate 2 is spaced apart from the inner barrel 1.

[0065] In an embodiment of the present invention, the bottom edge of the return water cover plate 2 is connected to a guide wall 242 that bends and extends away from the inner barrel 1. The guide wall 242 and the bottom of the inner barrel cooperate to form a guide port. Under the action of centrifugal force, the water at the bottom of the inner barrel flows to the outer periphery of the bottom of the inner barrel and enters the flow channel 201 through the guide port, and flows upward along the flow channel 201 into the filter assembly 3.

[0066] In an embodiment of the present invention, the return water cover plate 2 is provided with a receiving groove 243 with the groove facing the installation port 220 for accommodating the filter assembly 3. The groove wall of the receiving groove 243 is connected to the periphery of the installation port 220, and the bottom of the receiving groove 243 is provided with an opening communicating with the flow channel 201. Preferably, the support structure 210 is located below the bottom opening of the receiving groove 243. After the filter assembly 3 is installed in the receiving groove 243 through the installation port 220, the bottom of the filter assembly 3 extends into the flow channel 201 through the groove of the receiving groove 243 and abuts against the support structure 210.

[0067] In an embodiment of the present invention, the filter assembly 3 includes a housing 301 with a filter grid and a back plate 302. The filter grid of the housing 301 faces the outside of the filter assembly 3 through the mounting port 220, and the back plate 302 is in contact with the bottom of the receiving groove 243. Preferably, the bottom of the housing 301 and the bottom of the back plate 302 cooperate to form a water inlet. Water in the flow channel 201 enters the interior of the filter assembly 3 through the water inlet, flows to the outside of the filter assembly 3 through the filter grid, and flows back to the inner tank. The lint in the water is filtered by the filter grid and remains inside the filter assembly 3.

[0068] In an embodiment of the present invention, the bottom edge of the cover 301 abuts against the bottom edge of the mounting port 220, the inner side of the bottom edge of the cover 301 is connected to the abutment structure 310, and the abutment structure 310 is fitted to the inner side wall of the return water cover 2 located below the mounting port 220.

[0069] In one embodiment of the present invention, the first wall 211 of the support structure 210 is perpendicular to the extension direction of the flow channel 201, so that the first wall 211 of the support structure 210 can form a rigid support in the vertical direction.

[0070] In another embodiment of the present invention, the support structure 210 extends obliquely towards the filter assembly 3 along the protruding direction; by setting the first wall 211 at an angle, a wedge-shaped support can be formed, and the filter assembly 3 can generate a self-locking effect during installation, further enhancing the fixing effect. When the filter assembly 3 shifts under the impact of water flow or the shaking of the inner barrel, the filter assembly 3 can automatically correct its deviation under the guidance of the first wall 211, improving the stability of the filter assembly 3 installation.

[0071] In another embodiment of the present invention, the connecting end portion of the first wall 211 that connects to the return water cover plate 2 is perpendicular to the extension direction of the flow channel 201, and the portion near the extension end extends obliquely towards the filter assembly 3 along the protruding direction; so that the first wall 211 has the technical effects of the above two embodiments at the same time, and when the oblique portion guides the filter assembly 3 to reset, the connecting end portion can provide a stable support force parallel to the extension direction of the flow channel 201 to the filter assembly 3, thereby forming a more stable support effect.

[0072] In an embodiment of the present invention, the support structure 210 is plate-shaped, and the plate surface of the support structure 210 is parallel to the extension direction of the flow channel 201. The plate-shaped support structure 210 is parallel to the extension direction of the flow channel 201, which can provide uniform support force along the direction of the flow channel 201, effectively preventing the filter assembly 3 from displacement or shaking under high-speed water flow. The plate surface design of the support structure 210 reduces water flow resistance, allowing water to flow more smoothly through the flow channel 201, improving the lint filtration effect, and reducing the accumulation and blockage of lint in the flow channel 201.

[0073] In an embodiment of the present invention, the second wall 212 at the bottom of the support structure 210 extends upward in a protruding direction to form a wedge-shaped support structure 210. The inclined second wall 212 can guide the water flow to form a smoother path and reduce water flow resistance.

[0074] In embodiments of the present invention, the filter assembly 3 and / or the return water cover 2 are provided with a limiting structure 250, and the return water cover 2 and / or the filter assembly 3 are provided with a limiting groove 370 corresponding to the limiting structure 250, and the limiting groove 370 is open.

[0075] By setting the limiting structure 250 and the corresponding limiting groove 370, the assembly method between the filter assembly 3 and the return water cover 2 is increased, further improving the stability of their assembly. At the same time, the limiting groove 370 is open, so that when the filter assembly 3 is rotated and aligned, the top shell of the limiting groove 370 and the extended end face of the limiting structure 250 are fitted onto the limiting structure 250 in a way that avoids mutual contact, making the installation of the filter assembly 3 smoother.

[0076] In embodiments of the present invention, the cross-section of the limiting structure 250 gradually decreases along the extending direction, and the limiting structure 250 and the limiting groove 370 are shaped to fit together; so that after the filter assembly 3 is installed on the return water cover plate 2, the shape-fitting insertion of the limiting structure 250 and the limiting groove 370 improves the stability of the connection between the two.

[0077] In an embodiment of the present invention, the return water cover plate 2 is provided with an assembly groove for accommodating the filter assembly 3, the limiting structure 250 protrudes from the bottom of the assembly groove, and the limiting groove 370 is formed by the filter assembly 3 recessed inward; preferably, the protruding length of the limiting structure 250 is less than or equal to the groove depth of the assembly groove; so that the assembly groove covers the limiting structure 250, which facilitates the installation of the filter assembly 3, while improving the structural strength of the limiting structure 250, and preventing the limiting structure 250 from being damaged by external hard objects.

[0078] In an embodiment of the present invention, the left and right sides of the cover 301 are provided with edges that bend and extend toward the back plate 302, and the two sides extend to the left and right sides of the back plate 302 respectively, and the end faces of the extended ends of the two sides are provided with recessed limiting grooves 370.

[0079] In an embodiment of the present invention, the limiting structure 250 is located on the outer periphery of the bottom of the assembly groove and is connected to the groove wall of the assembly groove to further enhance the structural strength of the limiting structure 250.

[0080] In an embodiment of the present invention, a one-way valve 320 is provided inside the filter assembly 3. The one-way valve 303 includes a valve body 320 and a fixing part 330 connected to the valve body 320. The fixing part includes a first part 331 and a second part 332. The first part 331 and the second part 332 are different from each other and / or are asymmetrically distributed relative to the valve body 320. The filter assembly 3 is provided with an assembly structure 340 that matches the fixing part 330.

[0081] By setting the first part 331 and the second part 332 to have differences in shape, size or protrusion length, and by setting a corresponding matching assembly structure 340 on the filter assembly 3, it can be ensured that the first part 331 and the second part 332 are stably installed on the assembly structure 340 only when the one-way valve 303 is installed in the correct manner. This ensures that the valve body 320 cannot be incorrectly installed by rotation or mirror symmetry during assembly, significantly reducing the assembly error rate of the valve body 320 and reducing human error.

[0082] In an embodiment of the present invention, one end of the valve body 320 is a free end 322 that opens under the action of forward-flowing water, and the other end is a fixed end 321; the fixed part 330 is connected to the end face of the fixed end 321, and the first part 331 and the second part 332 respectively protrude from the peripheral sidewall of the fixed end. The fixed end 321 serves as a connection anchor point to ensure a stable connection between the valve body 320 and the filter assembly 3.

[0083] In one embodiment of the present invention, the first part 331 and the second part 332 are asymmetrically distributed on the peripheral sidewall of the fixed end 321 of the valve body 320; this ensures that the valve body 320 can only be installed on the assembly structure 340 in the correct installation manner, thereby ensuring that the valve body 320 cannot be incorrectly installed by rotation or mirror symmetry during assembly.

[0084] In another preferred embodiment of the present invention, the first part 331 and the second part 332 are symmetrically distributed on the periphery of the valve body 320, and the fixing parts 330 are different from each other.

[0085] With the above arrangement, the first part 331 and the second part 332 are symmetrically distributed on the side wall of the valve body 320, forming a uniform stress point, which can disperse stress concentration and enhance the stability of the connection between the one-way valve 303 and the filter assembly 3. In addition, by making the first part 331 and the second part 332 different from each other, incorrect assembly is physically prevented. Operators can quickly distinguish the installation direction of the one-way valve 303 by visual inspection or touch, shortening the assembly time and reducing the rework rate.

[0086] In an embodiment of the present invention, the first part 331 and the second part 332 are arranged on both sides of the fixed end 321 along the positive direction of water flow; the first part 331 and the second part 332 on both sides of the valve body 320 form symmetrical support, disperse stress concentration, and enhance the vibration resistance of the valve body 320.

[0087] In embodiments of the present invention, the connection methods between the first part 331 and the second part 332 and the assembly structure 340 are different from each other; preferably, the first part 331 and the second part 332 are connected to the assembly structure 340 by welding, snap-fitting, plugging or screwing.

[0088] In embodiments of the present invention, the first part 331 and the second part 332 are respectively connected to the corresponding assembly structure 340 in the same way, and the shapes and / or external dimensions of the first part 331 and the second part 332 are different from each other.

[0089] The above settings reduce the need to switch between different connection methods during assembly, lower operational complexity, and allow operators to quickly assemble the first part 331 and the second part 332 using a unified connection action, significantly shortening assembly time and improving production line efficiency. Furthermore, by making the difference in shape and / or external dimensions between the first part 331 and the second part 332 physically prevents incorrect assembly, operators can quickly distinguish the first part 331 and the second part 332 by sight or touch, further reducing the possibility of misassembly and improving assembly accuracy.

[0090] In the embodiments of the present invention, the first part 331 and the second part 332 have the same shape but different external dimensions; the size difference between the first part 331 and the second part 332 physically prevents incorrect assembly, and further simplifies the processing technology of the first part 331 and the second part 332, reducing production costs.

[0091] In an embodiment of the present invention, the fixing part 330 is provided inside the assembly structure 340 in a shape fit. The first part 331 and the second part 332 extend from the connection with the valve body 320, and the protrusion length and / or cross-sectional shape or size perpendicular to the protrusion direction of the first part 331 and the second part 332 are different from each other; the mis-proof function is achieved by the shape fit.

[0092] In an embodiment of the present invention, the fixing part 330 is a sheet-like structure with uniform thickness. The end face of the fixing end 321 of the valve body 320 is connected to one side surface of the fixing part 330. The protruding lengths of the first part 331 and the second part 332 are not equal. The end faces of the protruding ends of the first part 331 and the second part 332 are connected to the corresponding side chamber walls of the internal chamber of the assembly structure 340. By setting the first part 331 and the second part 332 with different protruding lengths and making the shape of the assembly structure 340 fit, when the one-way valve 303 is rotated 180° and misinstalled, the longer one of the first part 331 and the second part 332 cannot be properly installed in the assembly structure 340, thereby reminding the operator of the installation error.

[0093] In the embodiments of the present invention, the protruding length of the first part 331 is less than the protruding length of the second part 332; the first part 331 and the second part 332 are respectively disposed on two opposite sides of the valve body 320, forming an arrangement along the positive direction of the water guide channel, so as to avoid the one-way valve 303 being rotated 180° and misinstalled; in addition, the larger second part 332 provides the main support force. When the valve body 320 is flipped in the positive direction of the water guide channel by the action of water flow, the second part 332 can provide a stable support force to prevent the fixed end 321 of the valve body 320 from being relatively displaced from the filter assembly 3.

[0094] In embodiments of the present invention, the protruding length of the second part 332 is greater than or equal to 1.5 times the protruding length of the first part 331, and less than or equal to 3 times the protruding length of the first part 331; the proportional limitation ensures that the height difference of the fixing part 330 is significant, while avoiding excessive difference that may lead to assembly difficulties or structural instability.

[0095] In an embodiment of the present invention, the protruding length of the second part 332 is greater than or equal to twice the protruding length of the first part 331, and less than or equal to 2.5 times the protruding length of the first part 331.

[0096] In one embodiment of the present invention, the assembly structure 340 is an assembly groove 341 provided on the filter assembly 3, and the fixing part 330 is welded or bonded to the assembly groove 341 in a shape-fitting manner.

[0097] In another preferred embodiment of the present invention, the fixing part 330 is detachably installed in the assembly structure 340; so that when the valve body 320 fails due to long-term use or the connection between the valve body 320 and the fixing part 330 breaks, the lint filter can be restored to normal operation by replacing the one-way valve 303.

[0098] In an embodiment of the present invention, the assembly structure 340 includes an assembly groove 341 for providing space to accommodate the fixing part 330, and a valve body 320 extending outward from the groove opening of the assembly groove 341; a first assembly rib 342 and a second assembly rib 343 extending towards each other from opposite sides of the groove wall of the assembly groove 341, the corresponding portions of the first assembly rib 342 and the bottom of the assembly groove 341 being sandwiched on both sides of the first part 331, and the corresponding portions of the second assembly rib 343 and the bottom of the assembly groove 341 being sandwiched on both sides of the second part 332.

[0099] Through the above-mentioned configuration, the assembly groove 341 provides a precise installation position, ensuring a tight fit between the fixing part 330 and the filter assembly 3. The fixing part 330 can remain stable within the assembly groove 341 and is not prone to displacement or detachment. In addition, the first assembly rib 342 and the second assembly rib 343 respectively cooperate with the bottom of the assembly groove 341 to clamp the first part 331 and the second part 332 on both sides, enhancing the connection strength between the fixing part 330 and the assembly structure 340, and preventing the fixing part 330 from loosening or detaching due to water flow impact or vibration during use.

[0100] In embodiments of the present invention, the end faces of the extended ends of the first mounting rib 342 and the second mounting rib 343 are respectively in contact with the surface of the valve body 320; this increases the contact area between the mounting rib 342 and the fixing part 330, thereby improving the stability of the first mounting rib 342 and the second mounting rib 343 in limiting the first part 331 and the second part 332 respectively; at the same time, the extended ends of the first mounting rib 342 and the second mounting rib 343 limit the valve body 320 to prevent the valve body 320 from shifting; preferably, the sidewall of the first mounting rib 342 is in close contact with the first part 331, and the sidewall of the second mounting rib 343 is in close contact with the second part 332.

[0103] In an embodiment of the present invention, the fixed end 321 of the valve body 320 extends out of the assembly groove along the groove opening direction of the assembly groove 341, and the free end 322 of the valve body 320 extends obliquely from the fixed end in the positive direction of water; the extended end faces of each of the first assembly ribs 342 and the second assembly ribs 343 abut against the two side walls of the fixed end 321 respectively.

[0104] In an embodiment of the present invention, the width of the plate valve body 320 is equal to the width of the plate fixing part 330, so that the two sides of the valve body 320 and the fixing part 330 are flush.

[0105] In an embodiment of the present invention, the bottom of the assembly groove 341 is provided with a plurality of hollow holes; preferably, the projections of each first assembly rib 342 and second assembly rib 343 on the bottom of the assembly groove coincide with the hollow holes; so as to facilitate the installation of the fixing part 330.

[0106] In embodiments of the present invention, the fixing part 330 is integrally connected with the valve body 320.

[0107] In the embodiments of the present invention, each fixing part 330 is a polygonal sheet structure with equal thickness; preferably, each fixing part 330 is a quadrilateral sheet structure; more preferably, each fixing part 330 is a rectangular sheet structure.

[0108] In an embodiment of the present invention, a marking portion 380 is provided on the valve body 320 to indicate the orientation of the valve body 320; the marking portion 380 is provided on one side surface of the valve body 320; or, the marking portions 380 are provided on two opposite side surfaces of the valve body 320, and the two marking portions 380 are different from each other; so that the operator can confirm the correct installation direction of the one-way valve 303 through the marking portion, further reducing the assembly error rate of the valve body 320 and reducing human error.

[0109] In one embodiment of the present invention, the marking portion 380 is a pattern printed on the surface of the valve body 320.

[0110] In another preferred embodiment of the present invention, the marking portion 380 protrudes or is recessed on the surface of the valve body 320 to form an uneven texture on the surface of the valve body 320, so that the operator can confirm the correct installation direction of the one-way valve 303 by touch.
