Description
Technical Field
[0001] This utility model belongs to the field of washing machine technology, and specifically relates to a side wall filter fixture for washing machines. Background Technology
[0002] As an essential household appliance, the filtration and collection of impurities such as lint and fibers generated during the washing process has always been a key focus of the industry. In the existing technology, the filtration devices of washing machines are mainly divided into two types: bottom filtration and side wall filtration. Among them, the side wall filtration device is widely used in pulsator washing machines because of its advantages such as convenient installation location for users and no space occupied at the bottom of the drum.
[0003] According to Chinese Patent Publication No. CN217973744U, a filtration device for a pulsator washing machine includes a filter cover plate for installation on the side wall of the inner tub of the pulsator washing machine and a filter assembly for installation on the filter cover plate. The bottom of the filter cover plate is provided with a water passage channel. The filter assembly includes a filter screen cover installed on the filter cover plate, a filter base plate installed on the filter screen cover, a filter screen between the filter screen cover and the filter base plate, and the filter screen is installed on the back of the filter screen cover. A water inlet channel is enclosed between the filter screen cover and the filter base plate. A filter baffle is provided at the bottom of the filter base plate, and a gap for water flow is left between the filter baffle and the filter screen cover. The gap is connected to the water passage channel and the water inlet channel respectively.
[0004] However, the aforementioned devices, when combined with existing washing machine side-wall filters, all have problems. During the washing process, the inner tub rotates, causing water flow and clothes to continuously impact the side-wall filter mechanism. Clothing fibers and lint are intercepted through the filter screen to prevent them from entering the drain pump system. However, with increased use, lint gradually accumulates on the filter screen surface, forming a dense filter cake, which increases filtration resistance, reduces water flow rate, and affects washing efficiency. More importantly, existing technologies generally lack an effective self-cleaning mechanism. Users need to manually disassemble the filter screen periodically for cleaning. During cleaning, they need to come into contact with the adhered wet lint, and some filter cakes that have accumulated for a long time will embed into the mesh, forming stubborn fibers, causing the filter cake to stick to the filter screen, thus increasing the time required to clean the filter screen. Utility Model Content
[0005] In response to the problem in related technologies that lint gradually accumulates on the filter screen surface to form a dense filter cake, affecting washing efficiency and cleaning time, this utility model proposes a side wall filter fixture for washing machines to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a side wall filter fixture for a washing machine, including a mounting frame, a rotating filter mechanism inside the mounting frame, a water flow drive mechanism inside the rotating filter mechanism, a one-way rotation mechanism at the rotating end of the water flow drive mechanism, and a rotating cleaning mechanism at the filter end of the rotating filter mechanism.
[0008] The water flow impacts the water flow driving mechanism to rotate, so that the driving end of the water flow driving mechanism drives the filter end of the rotary filter mechanism to rotate, and the rotary filter mechanism synchronously drives the cleaning end of the rotary cleaning mechanism to rotate synchronously along the surface of the filter end.
[0009] Furthermore, the rotary filtering mechanism includes a protective net that is snapped onto the surface of the mounting frame. A support net is fixedly connected inside the mounting frame. Two rotating rods are rotatably connected inside the mounting frame, and circulating filter screens are engaged on the surfaces of the two rotating rods. The circulating filter screens slide along the surface of the support net.
[0010] Furthermore, the water flow driving mechanism includes a driving rod, which is rotatably connected inside the mounting frame. Several driving plates are fixedly connected to the surface of the driving rod. A gear one is fixedly connected to one end of the driving rod, and a gear two meshes with the surface of the gear one. The gear two is fixedly connected to one end of the rotating rod.
[0011] Furthermore, the rotating cleaning mechanism includes a cleaning rod, which is rotatably connected inside the mounting frame. Several scrapers are fixedly connected to the surface of the cleaning rod. A collection frame is slidably connected inside the mounting frame. Several scraping grooves are opened on one side of the collection frame, and several scrapers are slidably connected in the scraping grooves.
[0012] Furthermore, one end of the cleaning rod is fixedly connected to a gear three, and a connecting gear meshes with the surface of the gear three. The connecting gear is rotatably connected inside the mounting bracket, and the connecting gear meshes with gear two.
[0013] Furthermore, one side of the scraper contacts the surface of the circulating filter screen, and a collection column is rotatably connected inside the collection frame, with several winding columns fixedly connected to the surface of the collection column.
[0014] Furthermore, the one-way rotation mechanism includes a ratchet, one end of which is fixedly connected to a surface of a gear, and the ratchet surface is engaged with ratchet teeth, which are rotatably connected inside the mounting bracket. One end of the ratchet teeth is fixedly connected to a spring, and one end of the spring is fixedly connected inside the mounting bracket.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model uses water flow to drive a water flow mechanism to rotate, which in turn drives the filter end of the rotating filter mechanism to rotate. The rotating filter mechanism synchronously drives the cleaning end of the rotating cleaning mechanism to rotate along the surface of the filter end, thereby scraping away clothing fibers and lint from the filter end surface in real time. This design significantly reduces filtration resistance and increases water flow rate through the efficient conversion of water flow energy and the coordinated action of the mechanical structure. It effectively avoids the problem of reduced washing efficiency caused by the formation of a dense filter cake due to the accumulation of lint in traditional filters. At the same time, the real-time scraping mechanism can extend the lint cleaning cycle. For stubborn fibers embedded in the mesh, the relative movement of the rotating filter mechanism and the rotating cleaning mechanism creates shearing force, which can effectively peel off the adhered filter cake.
[0017] 2. This utility model utilizes the combined force of gravity and water flow impact when the amount of lint accumulates to a certain level, causing the winding column to undergo elastic deformation and rotate the collecting column. The gaps between the winding columns create a mechanical interlock, tightly winding the lint into a ball. When cleaning the lint, the protective net is opened, and the collecting frame is slid out. The ball of lint is then manually pulled to rotate the collecting column in the opposite direction. Under the combined action of centrifugal force and the elastic restoring force of the winding column, the ball of lint automatically peels off. This design improves the efficiency of lint cleaning and achieves centralized collection of lint, preventing lint from scattering and contaminating the inner drum of the washing machine during the cleaning process.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0030] Please see Figures 1-6 As shown, this utility model is a side wall filter fixture for a washing machine, including a mounting frame 1, a rotating filter mechanism 2 is provided inside the mounting frame 1, a water flow drive mechanism 3 is provided inside the rotating filter mechanism 2, a one-way rotation mechanism 4 is provided at the rotating end of the water flow drive mechanism 3, and a rotating cleaning mechanism 5 is provided at the filter end of the rotating filter mechanism 2.
[0031] The water flow impacts the water flow drive mechanism 3 to rotate, so that the drive end of the water flow drive mechanism 3 drives the filter end of the rotary filter mechanism 2 to rotate, and the rotary filter mechanism 2 synchronously drives the cleaning end of the rotary cleaning mechanism 5 to rotate synchronously along the surface of the filter end.
[0032] Water is filtered by flowing through the filter end of the rotary filter mechanism 2. At the same time, the water flow impacts the water flow drive mechanism 3 to rotate, so that the drive end of the water flow drive mechanism 3 drives the filter end of the rotary filter mechanism 2 to rotate. The rotary filter mechanism 2 synchronously drives the cleaning end of the rotary cleaning mechanism 5 to rotate synchronously along the surface of the filter end, scraping off the clothing fibers and lint filtered on the surface of the filter end in real time. The unidirectional rotation mechanism 4 ensures that the water flow drive mechanism 3 rotates in one direction and prevents the water flow drive mechanism 3 from reversing.
[0033] The water flow impacts the water flow drive mechanism 3, causing it to rotate. This drives the filter end of the rotary filter mechanism 2 to rotate, and the rotary filter mechanism 2 simultaneously drives the cleaning end of the rotary cleaning mechanism 5 to rotate along the surface of the filter end, scraping away the clothing fibers and lint filtered from the filter end surface in real time. This design significantly reduces filtration resistance and increases water flow rate through the efficient conversion of water flow energy and the coordinated action of the mechanical structure. It effectively avoids the problem of reduced washing efficiency caused by the formation of a dense filter cake due to the accumulation of lint in traditional filters. At the same time, the real-time scraping mechanism can extend the lint cleaning cycle. For stubborn fibers embedded in the mesh, the relative movement of the rotary filter mechanism 2 and the rotary cleaning mechanism 5 creates shearing force, which can effectively peel off the adhered filter cake.
[0034] In one embodiment, the rotary filter mechanism 2 includes a protective net 201, which is snapped onto the surface of the mounting frame 1. A support net 202 is fixedly connected inside the mounting frame 1. Two rotating rods 203 are rotatably connected inside the mounting frame 1. A circulating filter 204 is engaged on the surface of each of the two rotating rods 203. The circulating filter 204 slides along the surface of the support net 202.
[0035] The mounting bracket 1 is fixedly installed on the inner wall of the washing machine drum. The protective net 201 protects the internal parts of the mounting bracket 1 to prevent large impurities from entering the mounting bracket 1. The rotating rod 203 rotates, causing the circulating filter 204 to rotate along the surface of the support net 202, so that the circulating filter 204 is in dynamic filtration. Both the circulating filter 204 and the support net 202 can filter water.
[0036] In one embodiment, the water flow driving mechanism 3 includes a driving rod 301, which is rotatably connected inside the mounting frame 1. Several driving plates 302 are fixedly connected to the surface of the driving rod 301. A gear 303 is fixedly connected to one end of the driving rod 301. A gear 304 meshes with the surface of the gear 303. The gear 304 is fixedly connected to one end of the rotating rod 203.
[0037] When water flows through the interior of the mounting frame 1, the water flow impacts several drive plates 302, causing the drive plates 302 to drive the drive rod 301 to rotate, causing the drive rod 301 to drive the gear 1 303 to rotate, causing the gear 1 303 to drive the gear 2 304 to rotate, thereby causing the gear 2 304 to drive the rotating rod 203 to rotate, and causing the rotating rod 203 to drive the circulating filter screen 204 to rotate along the surface of the support screen 202.
[0038] In one embodiment, the rotating cleaning mechanism 5 includes a cleaning rod 501, which is rotatably connected inside the mounting frame 1. Several scrapers 502 are fixedly connected to the surface of the cleaning rod 501. A collection frame 503 is slidably connected inside the mounting frame 1. Several scraping grooves 504 are opened on one side of the collection frame 503. Several scrapers 502 are slidably connected in the scraping grooves 504. A gear 3 505 is fixedly connected to one end of the cleaning rod 501. A connecting gear 506 meshes with the surface of the gear 3 505. The connecting gear 506 is rotatably connected inside the mounting frame 1 and meshes with gear 2 304. One side of the scraper 502 contacts the surface of the circulating filter screen 204. A collection column 507 is rotatably connected inside the collection frame 503. Several winding columns 508 are fixedly connected to the surface of the collection column 507.
[0039] When gear two 304 rotates, gear two 304 drives gear three 505 to rotate via connecting gear 506. Gear three 505 drives cleaning rod 501 to rotate, causing cleaning rod 501 to drive several scrapers 502 to rotate along the surface of circulating filter screen 204, scraping away clothing fibers and lint filtered on the surface of circulating filter screen 204. The clothing fibers and lint reach one side of collection frame 503 through several scraping grooves 504 on one side of collection frame 503. When the scrapers 502 pass through the scraping grooves 504, the scraping grooves 504 scrape off the clothing fibers and lint on the surface of the scrapers 502, allowing the clothing fibers and lint to enter the collection frame 503. When clothing fibers and lint accumulate to a certain extent, they come into contact with several winding posts 508 on the surface of the collecting post 507, simultaneously squeezing the winding posts 508. This causes the winding posts 508 to rotate the collecting post 507, wrapping the clothing fibers and lint between the winding posts 508 and fixing them in place. When cleaning is required, the protective net 201 is opened, and the collecting frame 503 is slid out. Then, the clothing fibers and lint on the surface of the winding posts 508 are pulled, causing the collecting post 507 to rotate and peeling the clothing fibers and lint off the surface of the winding posts 508, completing the cleaning process. Finally, the collecting frame 503 and the protective net 201 are reset.
[0040] Meanwhile, the elastic winding post 508 is made of silicone, which can adapt to lint of different diameters and does not damage clothing fibers during the winding process.
[0041] In one embodiment, the unidirectional rotation mechanism 4 includes a ratchet 401, one end of which is fixedly connected to the surface of gear 303. A ratchet tooth 402 is engaged on the surface of the ratchet 401. The ratchet tooth 402 is rotatably connected inside the mounting frame 1. A spring 403 is fixedly connected to one end of the ratchet tooth 402. The spring 403 is fixedly connected to one end of the mounting frame 1.
[0042] When gear 303 rotates, it drives ratchet 401 to rotate, causing ratchet 401 to drive ratchet 402 to compress spring 403; when gear 303 rotates in the opposite direction, spring 403 drives ratchet 402 to engage with the surface of ratchet 401, preventing ratchet 401 from rotating, so that gear 303 can only rotate in one direction.
[0043] Through the above technical solution, 1. Water is filtered by flowing through the circulating filter screen 204 and the support screen 202. At this time, the water flow impacts several drive plates 302, causing the drive plates 302 to drive the drive rod 301 to rotate. The drive rod 301 drives the gear one 303 to rotate, which in turn drives the gear two 304 to rotate. This causes the gear two 304 to drive the rotating rod 203 to rotate, which in turn causes the circulating filter screen 204 to rotate along the surface of the support screen 202. The gear two 304 drives the gear three 504 through the connecting gear 506. 5. Rotation causes gear 3 505 to drive cleaning rod 501 to rotate, which in turn causes cleaning rod 501 to drive several scrapers 502 to rotate along the surface of circulating filter screen 204, scraping away clothing fibers and lint filtered on the surface of circulating filter screen 204. The clothing fibers and lint pass through several scrapers 502 to one side of collection frame 503, and then through several scraping grooves 504 on one side of collection frame 503. When scrapers 502 pass through scraping grooves 504, the scraping grooves 504 scrape away the clothing fibers and lint on the surface of scrapers 502, allowing the clothing fibers and lint to enter the collection frame 503.
[0044] 2. When clothing fibers and lint accumulate to a certain extent, they come into contact with several winding columns 508 on the surface of the collecting column 507, simultaneously squeezing the winding columns 508. This causes the winding columns 508 to rotate the collecting column 507, wrapping the clothing fibers and lint between them and fixing them in place. When cleaning is needed, the protective net 201 is opened, and the collecting frame 503 is slid out. Then, the clothing fibers and lint on the surface of the winding columns 508 are pulled, causing the collecting column 507 to rotate and peeling the clothing fibers and lint off the surface of the winding columns 508, completing the cleaning process. The collecting frame 503 and the protective net 201 are then reset. This facilitates centralized processing of the cleaned clothing fibers and lint, improving cleaning efficiency.
