Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and specifically relates to a micro lint collection device and a washing equipment. Background Art

[0002] Micro lint is the clothing fiber debris shed during the clothing washing process due to the friction between clothes and between clothes and the washing machine. Larger micro lint has a size of several millimeters in length. After being discharged into the water, it will enter the soil, causing soil compaction and affecting the growth of crops. Smaller micro lint has a size of only a few micrometers. Coupled with the widespread popularity of chemical fiber clothes at present, the micro lint generated during their washing process is also called microplastics, which can enter the human blood through the food chain.

[0003] Currently, researchers have found the above-mentioned micro lint in embryonic blood. Although the direct health impact of micro lint on humans is not yet clear, it has attracted the attention of the international community and intensive research is underway. Out of long-term consideration for human health, in some regions, hierarchical management of micro lint emissions has been implemented. In order to cut off micro lint emissions from the source, only washing equipment such as washing machines can be improved to filter and collect during the discharge of washing water.

[0004] Most of the existing devices used in washing equipment to filter micro lint achieve the filtering purpose through a filter screen. This filtering method through a filter screen, especially when filtering micro lint, is very likely to cause the filter screen to become blocked, thereby affecting the drainage efficiency of the washing equipment. At the same time, since it is not allowed to discharge micro lint into the environment through the sewer, it is often necessary for users to manually collect it after filtration and then perform post-treatment. The filter screen is easily blocked, so users often need to manually clean the filtered lint, resulting in a poor user experience.

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

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a micro lint collection device and a washing equipment, in which the core filtering structure is not easily blocked, ensuring the filtering efficiency and the drainage efficiency of the washing equipment.

[0007] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is:

[0008] A micro lint collection device includes:

[0009] A spiral filtering water channel, which extends downward in a spiral shape. The distance between the outer peripheral wall of the spiral filtering water channel and its central axis gradually decreases as the height decreases. Filtering holes for filtering micro lint are provided on the outer peripheral wall and / or the bottom wall of the spiral filtering water channel;

[0010] A chip discharge port, which is arranged at the extended end of the spiral filtering water channel;

[0011] A wire chip collection bin, which is arranged below the chip discharge port and receives the wire chips discharged from the chip discharge port.

[0012] Furthermore, the spiral filtering water channel has:

[0013] A first spiral fin, which is formed by bending a vertically arranged integral sheet material into a spiral structure with gradually decreasing height and gradually decreasing radial dimension, and is used to form the outer peripheral wall and the inner peripheral wall of the spiral filtering water channel;

[0014] A second spiral fin, which is connected to the first spiral fin and is used to form the bottom wall of the spiral filtering water channel;

[0015] A flow channel for water flow to pass through is formed between two adjacent turns of the spiral structure; in any two adjacent turns of the spiral structure, the lower side of the first spiral fin at the outer circle is connected to the second spiral fin, and the middle part of the first spiral fin at the inner circle is connected to the second spiral fin;

[0016] The filtering holes are arranged on the second spiral fin; and / or, the filtering holes are arranged on the first spiral fin and are located below the position where the middle part of the first spiral fin is connected to the second spiral fin.

[0017] Furthermore, the chip discharge port has a tubular structure extending downward from the bottom wall of the spiral filtering water channel; the top of the wire chip collection bin has a docking port matching the tubular structure, and the lower end of the tubular structure is inserted into the docking port.

[0018] Furthermore, the micro wire chip collection device further includes a machine shell, and both the spiral filtering water channel and the wire chip collection bin are arranged inside the machine shell;

[0019] The wire chip collection bin has water outlet holes that can intercept micro wire chips, and a drain port is arranged at the bottom of the machine shell;

[0020] Preferably, the water outlet holes are arranged on the circumferential side wall and / or the bottom wall of the wire chip collection bin; the top wall of the wire chip collection bin gradually rises from the outer periphery to the center, and the docking port is formed at the highest point, and no water outlet holes are arranged on the top wall.

[0021] Furthermore, a positioning boss is arranged on the bottom wall of the machine shell, and a positioning recess is arranged at the bottom of the wire chip collection bin, and the positioning recess is in limit fit with the positioning boss.

[0022] Furthermore, the casing includes an upper cover, a body, and a lower base; the body is a cylindrical structure with openings at both upper and lower ends, and the spiral filter water channel is arranged inside; the upper cover is used to close the upper opening of the body, and the lower base is used to close the lower opening of the body; the drain port is arranged on the lower base, and the lint collection bin is installed in a limiting and matching manner with the lower base.

[0023] Furthermore, a water inlet pipe is connected to the starting end of the spiral filter water channel, and the outlet direction of the water inlet pipe is parallel or nearly parallel to the extending direction of the spiral filter water channel at the starting end;

[0024] Preferably, the main section of the water inlet pipe extends downward from top to bottom to the height where the starting end of the spiral filter water channel is located, and an elbow is arranged at the lower end of the main section, which bends in a direction parallel or nearly parallel to the extending direction of the spiral filter water channel to form the outlet of the water inlet pipe.

[0025] Furthermore, the top side of the spiral filter water channel is open; the micro-lint collection device is provided with a flexible cleaning water pipe, and the cleaning water pipe extends vertically downward, and the lower end is located inside the spiral filter water channel;

[0026] During the process of the cleaning water pipe admitting water, the lower end of the cleaning water pipe swings under the reaction force of the water jet, whipping the spiral filter water channel;

[0027] Preferably, a fixed counterweight is arranged at the lower end of the cleaning water pipe.

[0028] Furthermore, the micro-lint collection device further includes a casing, and both the spiral filter water channel and the lint collection bin are arranged inside the casing; a rigid fixed pipe with a certain length is hermetically sleeved on the cleaning water pipe, and the fixed pipe penetrates through the top wall of the casing.

[0029] A washing device, and a drain pipe of the washing device is communicated with the spiral filter water channel of the above-mentioned micro-lint collection device.

[0030] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art.

[0031] In the present invention, the above-mentioned micro-lint collection device can be applied to a washing device to filter the discharged washing water. Among them, the washing water to be filtered flows spirally downward along the spiral filter water channel under the action of gravity and drainage power. During the flowing process, the water gradually seeps out from the filter holes, while the lint will continue to flow downward with the water flow and can finally be collected in the lint collection bin. Since the lint tends to extend along a direction close to the water flow direction, it is not easy to accumulate at the filter holes, and thus the filter holes are not easily blocked by the lint, and the filtering performance is more reliable.

[0032] In the present invention, a spiral filtering water channel is formed by the first spiral sheet and the second spiral sheet, and the radial dimension of the spiral filtering water channel gradually shrinks from top to bottom. The washing water filtered and discharged at the upper part will not fall back into the lower spiral filtering water channel again, ensuring that the amount of water finally discharged from the chip discharge port is as small as possible. The top wall of the wire chip collection bin is provided with a docking port that matches and docks with the tubular structure below the chip discharge port, and no water outlet holes are provided on the top wall to ensure that the washing water filtered and discharged from the upper spiral filtering water channel will not enter the wire chip collection bin.

[0033] In the present invention, the outlet direction of the water inlet pipe is parallel or nearly parallel to the extending direction of the spiral filtering water channel. On the one hand, it avoids the direct impact of the water flow on the filtering holes, thereby preventing the high impact force from directly blocking the filtering holes with the wire chips in the water. On the other hand, it can also provide the driving force for the water flow to advance along the spiral filtering water channel.

[0034] In the present invention, the spiral filtering water channel can be flushed by introducing water through the cleaning water pipe to achieve self-cleaning of the spiral filtering water channel. The cleaning water pipe is a flexible hose, and the lower end is suspended without fixation. When flushing the spiral filtering water channel by introducing water through the cleaning water pipe, the cleaning water sprays out from the lower end outlet of the cleaning water pipe. Furthermore, the lower end of the cleaning water pipe will be subjected to the reaction force of the water jet and swing irregularly. During the swinging process, it will whip the peripheral wall of the spiral filtering water channel, causing the spiral filtering water channel to vibrate. Cooperating with the cleaning water flow provided by the cleaning water pipe, it is easier to loosen the wire chips stuck in the filtering holes and let them leak out from the filtering holes. The setting of the counterweight can, on the one hand, gather the energy of the cleaning water pipe swinging and whipping the spiral filtering water channel, making it easier to cause the spiral filtering water channel to vibrate. On the other hand, it can limit the amplitude of the irregular swing of the lower end of the cleaning water pipe and prevent the lower end of the cleaning water pipe from being stuck by the spiral filtering water channel.

[0040] It should be noted that these drawings and textual descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. Detailed implementation manners

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0042] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0043] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] As Figure 1 and Figure 2 shown, the embodiments of the present invention provide a micro-lint collection device and a washing device applying the micro-lint collection device. Among them, the washing device may be a washing machine, a washing and drying integrated machine, a nursing machine, or other washing devices with a function of washing clothes.

[0045] In an embodiment of the present invention, the micro wire debris collection device can filter the washing water discharged by the washing device and then discharge it, filtering and collecting the micro wire debris that is not allowed to be directly discharged from the washing water. Specifically, the micro wire debris collection device at least has a filtering unit and a collection unit. The washing water discharged by the washing device first enters the filtering unit, and the wire debris in the water is separated in the filtering unit, and finally the wire debris is sent into the collection unit for collection.

[0046] However, with the use of the micro wire debris collection device, wire debris may remain and gradually accumulate in the filtering unit. When it is serious, it will cause blockage of the filtering unit and the filtering effect cannot be achieved continuously. At this time, the user needs to clean it manually. And if the filtering unit is prone to blockage, it will lead to a very frequent cleaning frequency for the user, and the user experience is not good.

[0047] Embodiment 1

[0048] As Figure 1 and Figure 2 shown, this embodiment provides a micro wire debris collection device and a washing device applying the micro wire debris collection device, which are used to solve the problem that the filtering unit of the micro wire debris collection device is easily blocked by wire debris.

[0049] Specifically, in this embodiment, the micro wire debris collection device includes a spiral filtering water channel 300 as the filtering unit and a wire debris collection bin 400 as the collection unit. Among them, the spiral filtering water channel 300 extends spirally downward, and the distance between its outer peripheral wall 311 and the central axis gradually decreases as the height decreases. Filtering holes 301 for filtering micro wire debris are provided on the outer peripheral wall 311 and the bottom wall 321 of the spiral filtering water channel 300, and a chip discharge port 330 is provided at the extending end of the spiral filtering water channel 300. The wire debris collection bin 400 is arranged below the chip discharge port 330 to receive the wire debris discharged from the chip discharge port 330.

[0050] As a specific implementation manner, the micro wire debris collection device further includes a housing 200, and the spiral filtering water channel 300 and the wire debris collection bin 400 are both arranged inside the housing 200. A drain port 501 is provided at the bottom of the housing 200, and a discharge pipe 500 extending downward is provided at the drain port 501.

[0051] The micro wire debris collection device described in this embodiment can be built into the washing device or externally connected and applied to the washing device. The drain pipe for the washing device to drain water is communicated with the spiral filtering water channel 300 to introduce the discharged washing water into the spiral filtering water channel 300.

[0052] The washing water entering the spiral filtering water channel 300 flows spirally downward along the spiral filtering water channel 300 under the action of gravity and drainage power. During the flowing process, the water can gradually seep out through the filtering holes 301 and fall into the casing 200. The water meeting the discharge standard in the casing 200 flows towards the drain port 501, and then can be discharged along the discharge pipe 500. The lint in the water cannot pass through the filtering holes 301 and will remain in the spiral filtering water channel 300 and continue to flow downward, and finally be discharged from the chip discharge port 330, so that it can be collected into the lint collection bin 400.

[0053] Through experiments and observations, it is found that during the process of the lint flowing forward with the water flow, the lint tends to extend along the direction close to the water flow. Specifically, referring to Figure 2 , the arrow in the figure indicates the water flow direction in the flow channel, and the water level line L in the flow channel is not higher than the highest position of the distribution area of the filtering holes 301 on the first spiral blade 310. The lint X in the water flows with the water flow in a transverse posture close to the direction of the arrow. The main flow direction of the washing water is forward along the flow channel, and there is basically no water flow directly flowing downward. Therefore, the filtering holes 301 are mainly for the freely flowing water droplets to drip down, and it is very difficult for the lint X to gather or pass through the filtering holes 301. Even if there are individual lint X sticking close to the filtering holes 301 and being sucked, due to the power brought by the forward flowing water flow exceeding the suction force of the filtering holes 301 on the lint X, the lint X will still be carried forward by the water flow.

[0054] Therefore, in this embodiment, the spiral filtering water channel 300 extending spirally downward is adopted to filter the washing water carrying lint, and it is not easy to have the problem of lint blocking the filtering holes 301, making the filtering performance of the micro lint collection device more reliable and eliminating the need for users to frequently perform manual cleaning.

[0055] In this embodiment, a plurality of filtering holes 301 are provided on both the outer peripheral wall 311 and the bottom wall 321 of the spiral filtering water channel 300.

[0056] In another embodiment, the filtering holes can be provided only on the outer peripheral wall or the bottom wall of the spiral filtering water channel, and the purpose of filtering the washing water can also be achieved.

[0057] However, it can be understood that setting the filtering holes only on the outer peripheral wall or the bottom wall, compared with the scheme of setting the filtering holes on both the outer peripheral wall and the bottom wall, the seepage rate of the washing water from the spiral filtering water channel is relatively low. Therefore, in order to ensure the separation effect of the washing water and the lint, it is necessary to appropriately extend the length of the spiral filtering water channel.

[0058] In a further solution of this embodiment, the spiral filtering water channel 300 is composed of a connected first spiral sheet 310 and a second spiral sheet 320. Among them, the first spiral sheet 310 forms the outer peripheral wall 311 and the inner peripheral wall 312 of each turn of the spiral filtering water channel 300, the second spiral sheet 320 forms the bottom wall 321 of the spiral filtering water channel 300, and the top side of the spiral filtering water channel 300 is open.

[0059] Specifically, the first spiral sheet 310 is a spiral structure formed by bending a vertically arranged integral sheet material with a gradually decreasing height and a gradually decreasing radial dimension. The flow channel for water flow to pass through in the spiral filtering water channel 300 is formed between two adjacent turns of the spiral structure. In any two adjacent turns of the spiral structure, the lower side of the first spiral sheet 310 at the outer circle is connected to the second spiral sheet 320, and the middle part of the first spiral sheet 310 at the inner circle is connected to the second spiral sheet 320.

[0060] That is to say, except for the areas of the outermost and innermost circles forming the spiral structure, the remaining areas of the first spiral sheet 310 are connected to the second spiral sheet 320 on both side surfaces. Among them, the surface of the first spiral sheet 310 facing the outer periphery is connected to the second spiral sheet 320 in the middle, and the surface facing the center is connected to the second spiral sheet 320 at the lower side.

[0061] With the above structure, the outer peripheral wall 311 and the inner peripheral wall 312 of the spiral filtering water channel 300 can be formed simultaneously by using the integral first spiral sheet 310. Among them, the upper region of the first spiral sheet 310 can be used as the inner peripheral wall 312 of one layer of the spiral filtering water channel 300, and its lower region can be used as the outer peripheral wall 311 of the next layer of the spiral filtering water channel 300.

[0062] Furthermore, the second spiral sheet 320 is provided with a plurality of filtering holes 301, so that the washing water can seep out through the bottom wall 321 of the spiral filtering water channel 300.

[0063] At the same time, a plurality of filtering holes 301 are also provided on the first spiral sheet 310, but the filtering holes 301 are only distributed in the lower region on the first spiral sheet 310. Specifically, when the surface of the first spiral sheet 310 facing the outer periphery is connected to the second spiral sheet 320, the filtering holes 301 on the first spiral sheet 310 are distributed below the position where it is connected to the second spiral sheet 320.

[0064] In this way, it is ensured that the filtering holes 301 are only distributed on the bottom wall 321 and the outer peripheral wall 311 of the spiral filtering water channel 300, and there are no filtering holes 301 on the inner peripheral wall 312. After the washing water seeps out through the filtering holes 301, it can drip downward and gather at the bottom of the machine housing 200, and then be discharged through the drain port 501 and the discharge pipe 500, without flowing inward, thereby avoiding the filtered water from flowing into the unfiltered water in the inner circle of the spiral filtering water channel 300.

[0065] The spiral filtration water channel 300 has a structure with a gradually shrinking radial dimension from top to bottom, such that the downward projections of various parts of its bottom wall 321 do not fall onto the structure of the spiral filtration water channel 300 itself. Thus, the water filtered out from the upper part of the spiral filtration water channel 300 will not flow into the unfiltered water in the lower part either.

[0066] With the above structure, during the process of the washing water flowing downward in the spiral filtration water channel 300, the closer to the lower end of the spiral filtration water channel 300, the less the water volume in the flow channel and the more the relative lint amount, which can ensure that the lint discharged from the chip discharge port 330 has as little water content as possible.

[0067] It can be understood that in this embodiment, the longer the extension length of the spiral filtration water channel 300, the more conducive to the full separation of lint and water. Therefore, in order to extend the length of the spiral filtration water channel 300 without overly increasing the overall volume of the micro-lint collection device, the height of each turn of the spiral filtration water channel 300 can be set to be smaller, that is, its inclination angle relative to the horizontal direction is smaller. At this time, the driving force for the washing water to flow along the spiral filtration water channel 300 mainly depends on the drainage power of the washing equipment.

[0068] As a specific implementation manner of this embodiment, the first spiral sheet 310 and the second spiral sheet 320 can be made of metal sheet material. After pre-drilling the metal sheet material and processing it into the shapes and structures corresponding to the first spiral sheet 310 and the second spiral sheet 320, the two are then fixed together by welding or other processes to form the spiral filtration water channel 300.

[0069] As another specific implementation manner of this embodiment, the first spiral sheet 310 and the second spiral sheet 320 can be respectively processed by an injection molding process and then connected together. Alternatively, the first spiral sheet 310 and the second spiral sheet 320 can also be integrally injection molded, thereby directly manufacturing the spiral filtration water channel 300 in one step. The filtration holes 301 can be processed after the injection molding is completed.

[0070] In a further aspect of this embodiment, the chip discharge port 330 has a tubular structure extending downward from the bottom wall 321 of the spiral filtration water channel 300. The top of the lint collection bin 400 has a docking port 410 matching the tubular structure, and the lower end of the tubular structure is inserted into the docking port 410.

[0071] As a specific structure, the chip discharge port 330 is a circular water pipe extending downward.

[0072] In the above solution, the docking port 410 at the top of the lint collection bin 400 is inserted and mated with the chip discharge port 330 of the tubular structure. Only the lint discharged through the chip discharge port 330 and a small amount of washing water that may exist can enter the lint collection bin 400, while the washing water filtered out by the spiral filter water channel 300 does not enter the lint collection bin 400.

[0073] Further, the lint collection bin 400 has a water outlet hole that can intercept micro lint. After the lint and a small amount of washing water enter the lint collection bin 400 together, the lint collection bin 400 can continue to filter the water in the lint, and discharge the washing water that can be directly discharged into the machine housing 200 through the water outlet hole, and then discharged through the drain port 501 and the discharge pipe 500. Only the lint in the washing water is collected inside the lint collection bin 400, and there is no water storage.

[0074] Specifically, the water outlet hole is provided on the peripheral side wall and / or the bottom wall of the lint collection bin 400, and there is no water outlet hole on the top wall of the lint collection bin 400. In this way, the top wall of the lint collection bin 400 can isolate water and prevent the filtered washing water from entering the lint collection bin 400.

[0075] It should be noted that the aperture of the water outlet hole should not be larger than the aperture of the filter hole 301 in the spiral filter water channel 300, so as to ensure that the lint entering the lint collection bin 400, especially the micro lint that is not allowed to be directly discharged, can be completely collected in the lint collection bin 400, and there will be no situation where the micro lint filtered out by the spiral filter water channel 300 is discharged again in the lint collection bin 400.

[0076] As a specific structure, the lint collection bin 400 has a cylindrical structure, and the cylindrical structure is provided with a mesh hole as the water outlet hole. The lower end of the cylindrical structure is closed by the bottom wall of the lint collection bin 400, and the upper end is connected with a frustum-shaped top wall 401. The frustum-shaped top wall 401 gradually rises from the outer periphery to the center and forms a docking port 410 at the highest point.

[0077] With the above structure, if the washing water dripping from the upper spiral filter water channel 300 falls on the frustum-shaped top wall 401 at the top of the lint collection bin 400, it can flow downward along the frustum-shaped top wall 401, and thus fall to the bottom of the machine housing 200, and there will be no problem of the washing water accumulating at the top of the lint collection bin 400.

[0078] In a further solution, the lint collection bin 400 is detachably arranged in the machine housing 200, and the user can regularly take out the lint collection bin 400 for cleaning or replacement to clean the lint accumulated in the lint collection bin 400. Specifically, the machine housing 200 has a detachable lower bottom 230, which is convenient for the user to clean or replace the lint collection bin 400.

[0079] Further, a positioning boss 231 is arranged inside the lower base 230, and the bottom of the lint collection bin 400 has a positioning recess 420. The positioning recess 420 is in limiting cooperation with the positioning boss 231 for positioning the lint collection bin 400 inside the casing 200, facilitating the reset of the lint collection bin 400 after the user cleans or replaces the lint collection bin 400. The drain port 501 for discharging the filtered washing water is also arranged on the lower base 230.

[0080] As a specific structure, the casing 200 includes an upper cover 220, a body 210, and a lower base 230. Among them, the body 210 is a cylindrical structure with openings at both upper and lower ends, and a spiral filter water channel 300 is arranged inside. The upper cover 220 closes the upper opening of the body 210, and the lower base 230 closes the lower opening of the body 210.

[0081] The setting of the upper cover 220 facilitates the installation and fixation of the spiral filter water channel 300 inside the body 210 during the production process of the micro lint collection device. A later detachable connection method such as threaded connection or snap connection can be adopted between the upper cover 220 and the body 210. Or, after the spiral filter water channel 300 is installed, the upper cover 220 and the body 210 can be connected into one body by welding process.

[0082] A connection structure convenient for disassembly and assembly such as threaded connection or snap connection can be adopted between the lower base 230 and the body 210. When the lint collection bin 400 is full of lint, the user can open the lower base 230 to take out the current lint collection bin 400.

[0083] In a specific embodiment, the lint collection bin 400 can be reused. After the user takes out the lint collection bin 400, cleans the lint collected inside it, and then can place the cleaned lint collection bin 400 back on the lower base 230 so that the positioning recess 420 is just placed at the positioning boss 231 to achieve rough positioning. Then, the user can fasten the lower base 230 to the lower end of the body 210.

[0084] In this way, when the user installs the lint collection bin 400, there is no need to precisely align the docking port 410 at the top with the chip discharge port 330 at the lower end of the spiral filter water channel 300, and the installation can be more convenient, realizing anti-fool operation.

[0085] In another specific embodiment, the lint collection bin 400 is a disposable consumable. After the user takes out the lint collection bin 400, it can be directly discarded, and then a new lint collection bin 400 is placed on the lower base 230, and then the lower base 230 is fastened to the lower end of the body 210. In this way, the user does not need to contact the filtered lint and can complete the replacement more hygienically and quickly.

[0086] In a further aspect of this embodiment, a water inlet pipe 110 is connected to the starting end of the spiral filtering water channel 300, and the outlet direction of the water inlet pipe 110 is parallel or nearly parallel to the extending direction of the spiral filtering water channel 300 at the starting end.

[0087] As a specific implementation, the main body section 112 of the water inlet pipe 110 extends from top to bottom to the height where the starting end of the spiral filtering water channel 300 is located. An elbow 111 is provided at the lower end of the main body section 112. The elbow 111 bends from the lower end of the main body section 112 to be parallel or nearly parallel to the extending direction of the spiral filtering water channel 300, and the end forms the outlet of the water inlet pipe 110.

[0088] In a specific structure, the main body section 112 of the water inlet pipe 110 extends from top to bottom through the upper cover 220 and extends into the flow channel of the uppermost circle from the top-side opening of the spiral filtering water channel 300. The elbow 111 at the lower end of the main body section 112 is placed in the uppermost circle of the spiral filtering water channel 300.

[0089] By providing the elbow 111, when the washing water enters the spiral filtering water channel 300, the water outlet direction is basically the same as the extending direction of the spiral filtering water channel 300 at this position, which can avoid the water flow directly impacting the filtering holes 301 on the spiral filtering water channel 300, thereby preventing the lint in the water from directly blocking the filtering holes 301 due to excessive impact force. On the other hand, when the washing water flows out from the outlet of the water inlet pipe 110, it has a certain flow rate, and the water outlet direction is basically the same as the direction in which the washing water continues to flow along the spiral filtering water channel 300, which can also provide the driving force for the water flow to advance along the spiral filtering water channel 300.

[0090] When the micro lint collection device described in this embodiment is applied to a washing device, as a specific implementation, the micro lint collection device is built into the washing device. At this time, the water inlet pipe 110 can directly use the drain pipe of the washing device, or the drain pipe of the washing device can be connected to the water inlet pipe 110.

[0091] As another specific implementation, the micro lint collection device is externally connected to the washing device. Specifically, the drain pipe of the washing device extends out of the box body of the washing device, and the drain pipe is connected to the water inlet pipe 110, so as to introduce the washing water discharged from the washing device into the spiral filtering water channel 300.

[0092] In this embodiment, the micro-lint collection device is provided with a spiral filter water channel 300 that extends downward in a spiral and gradually shrinks in radial dimension. This is used to filter the wash water discharged from the washing equipment. Filter holes 301 are provided on the outer peripheral wall 311 and bottom wall 321 of the spiral filter water channel 300. As the wash water flows downward along the spiral filter water channel 300, the water gradually seeps out of the filter holes 301 and gathers at the bottom of the housing 200 for discharge. Lint in the water mainly extends horizontally with the flow of water and is less likely to gather and pass through the filter holes 301. This prevents the filter holes 301 on the spiral filter water channel 300 from being clogged by lint, providing more stable filtering performance.

[0093] Embodiment 2

[0094] like Figure 1 and Figure 2 As shown, this embodiment is a further limitation of the above-mentioned embodiment 1. The micro-lint collecting device is provided with a cleaning water pipe 120, and clean water can be injected into the spiral filter water channel 300 through the cleaning water pipe 120 to flush and clean the spiral filter water channel 300.

[0095] Specifically, in this embodiment, the cleaning water pipe 120 is a flexible hose that extends vertically from top to bottom, with its lower end extending into the interior of the spiral filter water channel 300. More specifically, the cleaning water pipe 120 is installed through the upper cover 220 of the housing 200 and is relatively fixed at the position where it passes through the upper cover 220. The lower end of the cleaning water pipe 120 is suspended in the interior of the spiral filter water channel 300 and is not fixed.

[0096] In one embodiment, the cleaning water pipe 120 is directly connected to tap water via a solenoid valve. When the solenoid valve is opened, since the cleaning water pipe 120 is a flexible hose with no fixed lower end, when tap water is ejected from the outlet of the cleaning water pipe 120, the lower end of the cleaning water pipe 120 is subjected to the reaction force of the water jet, causing it to swing irregularly.

[0097] During the oscillation process, the cleaning water pipe 120 whips the sidewalls of the spiral filter channel 300, namely the first spiral plate 310, causing the spiral filter channel 300 to vibrate. This allows any lint stuck in the filter holes 301 to be easily loosened by the vibration of the spiral filter channel 300. The cleaning water flow from the cleaning water pipe 120 into the spiral filter channel 300 allows the lint trapped in the filter holes 301 to flow out of the filter holes 301, preventing blockage. Furthermore, the irregular oscillation of the lower end of the cleaning water pipe 120 also increases the flushing area of the tap water in the spiral filter channel 300, thereby more thoroughly cleaning the inner walls of the spiral filter channel 300 and flushing away any lint adhering to the bottom wall 321.

[0098] It can be understood that the lint that can pass through the filter holes 301 has a diameter smaller than the aperture of the filter holes 301. The lint of this size is the lint permitted by regulations to be discharged and will not cause the washing water discharge to fail to meet the standards.

[0099] In a preferred solution, a fixed counterweight 122 is provided at the lower end of the cleaning water pipe 120. As a specific structure, the counterweight 122 is a counterweight ring fixedly sleeved on the lower end of the cleaning water pipe 120.

[0100] In this way, when tap water is introduced into the cleaning water pipe 120, the energy of its lower end swinging and whipping the first spiral blade 310 is greater, and then it is easier to vibrate the spiral filter channel 300, so that the lint entering the filter holes 301 leaks down and the blockage of the filter holes 301 is removed.

[0101] In a specific implementation manner of this embodiment, the cleaning water pipe 120 extends downward into the spiral filter channel 300 to a greater depth. On the one hand, the radial dimension of the spiral filter channel 300 at the height where the lower end of the cleaning water pipe 120 is located is relatively small, ensuring that the random swing of the lower end of the cleaning water pipe 120 can contact the first spiral blade 310, and then vibrating the spiral filter channel 300, so that the lint in the filter holes 301 is loosened under the vibration. On the other hand, it can also avoid the situation where the cleaning water pipe 120 is accidentally swung and stuck by the spiral filter channel 300 and cannot get out of trouble, and thus cannot continue to whip the spiral filter channel 300.

[0102] When the counterweight 122 is provided at the lower end of the cleaning water pipe 120, the counterweight 122 can also limit the amplitude of the random swing of the lower end of the cleaning water pipe 120, and then gather energy to whip the spiral filter channel 300, without swinging too much and being stuck by the spiral filter channel 300.

[0103] In a further solution of this embodiment, a fixed pipe 121 with a certain length is hermetically sleeved on the cleaning water pipe 120. The fixed pipe 121 is made of a rigid pipe, is relatively fixed to the cleaning water pipe 120, and there is a certain distance between the lower end of the fixed pipe 121 and the lower end of the cleaning water pipe 120. The fixed pipe 121 passes through the middle of the upper cover 220, so as to realize the relative fixation of the cleaning water pipe 120 and the upper cover 220.

[0104] In a specific structure, the middle of the fixed pipe 121 is relatively fixed to the upper cover 220. That is, the upper end of the fixed pipe 121 is higher than the upper surface of the upper cover 220, and the lower end is lower than the lower surface of the upper cover 220.

[0105] By providing the fixed pipe 121, it is easier to install and fix the cleaning water pipe 120 and the upper cover 220. At the same time, it makes the cleaning water pipe 120 deformed only when it is at a certain height lower than the upper cover 220, further limiting the swing amplitude of the lower end of the cleaning water pipe 120.

[0106] As a specific implementation manner of this embodiment, during the drainage process of the washing device, clean water can be intermittently injected along the cleaning water pipe 120, for example, controlling the electromagnetic valve connected to the cleaning water pipe 120 to be intermittently opened. In this way, cleaning water flow can be intermittently provided to the spiral filtering water channel 300, and the spiral filtering water channel 300 can be vibrated by whipping the first spiral blade 310 to prevent the filtering holes 301 from being blocked by lint, ensuring the filtering efficiency.

[0107] As another specific implementation manner of this embodiment, clean water can also be injected through the cleaning water pipe 120 when the drainage process of the washing device is approaching the end, that is, opening the electromagnetic valve connected to the cleaning water pipe 120 at the end stage of the drainage of the washing device. After the electromagnetic valve is opened, it remains open for a period of time, so as to wash down the lint adhering to the bottom wall 321 of the spiral filtering water channel 300 during the drainage process of the washing device this time, and discharge it into the lint collection bin 400 through the chip discharge port 330. At the same time, the lint stuck in the filtering holes 301 leaks down under the action of vibration, ensuring the filtering effect during the next filtration.

[0108] In this embodiment, the micro lint collection device is provided with a cleaning water pipe 120, which can provide cleaning water flow to the spiral filtering water channel 300 to wash the lint adhering to the bottom wall 321 and prevent the filtering holes 301 from being covered by lint. The cleaning water pipe 120 adopts a flexible hose. During the water injection process, the lower end of the cleaning water pipe 120 generates random swinging under the reaction force of the water jet, and cooperates with the counterweight 122 fixed at the lower end of the cleaning water pipe 120 to accumulate energy and whip the peripheral side wall of the spiral filtering water channel 300, driving the spiral filtering water channel 300 to vibrate, making it easier for the lint stuck in the filtering holes 301 to loosen and leak from the filtering holes 301. In this way, the micro lint collection device can realize the self-cleaning of the spiral filtering water channel 300, avoiding the problem that the filtering holes 301 are blocked by lint and affecting the filtering effect.
