Description

Technical Field

[0001] This application relates to the field of washing equipment, and more particularly to a wastewater filtration device for a washing machine. Background Technology

[0002] Polyester is a fiber-forming polymer made from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions. It is produced through spinning and post-treatment, and its greatest advantages are excellent wrinkle resistance and shape retention. Generally, fabrics require pre-treatment before and after dyeing, including washing, usually using a washing machine.

[0003] Chinese Patent CN219032630U discloses a wastewater filtration device for a washing machine. The wastewater circulation device includes a drain pipe, a wastewater filtration structure, and a return pipe. One end of the drain pipe is connected to the drain outlet of the washing machine, and the other end is connected to the wastewater filtration structure. One end of the return pipe is connected to the wastewater filtration structure, and the other end is connected to the inlet of the washing machine. The wastewater filtration structure includes a wastewater filter box and a filter screen detachably installed inside the wastewater filter box. The filter screen has multiple filter holes evenly distributed throughout it. The application has the following effects: the washing liquid in the washing machine enters the wastewater filtration structure through the drain port and drain pipe. After impurities are filtered in the wastewater filtration structure, it returns to the washing machine through the return pipe. The wastewater filtration structure filters impurities in the washing liquid, reduces the impurity content of the washing liquid, improves the washing effect of the washing machine on the fabric, and also improves the utilization rate of the washing liquid to a certain extent.

[0004] Regarding the aforementioned technologies, when wastewater passes through the filter screen, impurities in the wastewater accumulate on the surface of the filter screen, which may clog the filter holes and affect the filtration efficiency. Utility Model Content

[0005] In order to minimize the clogging of the filter plate by impurities and improve the wastewater filtration efficiency, this application provides a wastewater filtration device for a washing machine.

[0006] The wastewater filtration device for a washing machine provided in this application adopts the following technical solution:

[0007] A wastewater filtration device for a washing machine includes a recycling bin and a filter plate. The filter plate is connected inside the recycling bin, and a water outlet pipe is connected to the bottom of the recycling bin. A scraper is connected to the top of the filter plate, and the length direction of the scraper is consistent with the radial direction of the filter plate. The bottom of the scraper contacts the top of the filter plate, and the scraper is rotatably connected to the top of the filter plate. A rotating assembly is connected to the recycling bin, and the rotating assembly is used to drive the scraper to rotate.

[0008] By adopting the above technical solution, wastewater enters the recycling tank through the filter plate. The filter plate filters the wastewater, thereby reducing impurities in the wastewater. When the wastewater passes through the filter plate, the rotating component drives the scraper to rotate, which pushes away the impurities adhering to the top of the filter plate, thus avoiding the situation where impurities clog the filter plate as much as possible and improving the wastewater filtration efficiency.

[0009] Optionally, a rotating rod is rotatably connected inside the recycling bin. The length direction of the rotating rod is consistent with the vertical direction. The top of the rotating rod passes through the bottom of the filter plate. The rotating assembly is used to drive the rotating rod to rotate. A mounting cover is slidably fitted on the top of the rotating rod. The central axis of the mounting cover is collinear with the central axis of the rotating rod. The mounting cover is slidably connected to the rotating rod in the vertical direction. A locking assembly is connected to the rotating rod. The locking assembly is used to lock the mounting cover onto the rotating rod. The scraper is connected to the periphery of the mounting cover.

[0010] By adopting the above technical solution, the first motor drives the rotating rod to rotate, causing the mounting cover and scraper to rotate with the rotating rod. This causes the scraper to push the impurities on the top of the filter plate, thereby reducing the situation where impurities clog the filter plate. In addition, the mounting cover is detachably connected to the rotating rod through the locking component, which facilitates cleaning and replacement of the scraper.

[0011] Optionally, a mounting groove is provided on the periphery of the top end of the rotating rod. The length direction of the mounting groove is consistent with the radial direction of the rotating rod. The locking assembly includes a first spring and a locking block. The length direction of the first spring is consistent with the length direction of the mounting groove. One end of the first spring is connected to the inner wall of the mounting groove along its length direction, and the other end of the first spring is connected to the locking block. The locking block is slidably connected to the mounting groove along its length direction. The inner wall of the mounting cover is provided with a locking groove for the locking block to be embedded in. In use, the locking block is embedded in the locking groove.

[0012] By adopting the above technical solution, when installing the mounting cover, the locking block is pushed so that it is embedded in the mounting groove. The locking block compresses the first spring, causing the first spring to deform. The mounting cover is then placed on the top of the rotating rod, so that the locking block is close to the locking groove. When the locking block is close to the locking groove, the first spring returns to its shape and pushes the locking block to move along the length of the mounting groove, so that the locking block is embedded in the locking groove. This makes the mounting cover stably connected to the top of the rotating rod.

[0013] Optionally, the rotating rod is a telescopic rod, which includes a connecting rod and a sleeve rod. The sleeve rod is slidably fitted onto the connecting rod. The central axis of the connecting rod is collinear with the central axis of the sleeve rod and the central axis of the recycling bin. The bottom end of the connecting rod passes vertically through the bottom of the recycling bin, and the top end of the connecting rod passes vertically through the filter plate. The connecting rod is slidably connected to the recycling bin, the sleeve rod, and the filter plate in the vertical direction. The recycling bin is connected to a lifting component, which is used to drive the connecting rod to move in the vertical direction. The locking component is connected to the bottom end of the connecting rod, and the bottom of the locking block is provided with a guide surface. The guide surface is inclined and facilitates the locking block to move away from the locking groove.

[0014] By adopting the above technical solution, when disassembling the connecting barrel, the lifting component drives the connecting rod to move downward in the vertical direction. The guide surface contacts the inner wall of the mounting cover. Under the guidance of the guide surface, the locking block is squeezed into the mounting groove by the inner wall of the mounting cover, so that the connecting rod moves away from the mounting cover, thereby facilitating the disassembly of the mounting cover.

[0015] Optionally, the recycling bin is equipped with a connecting barrel, the central axis of which is collinear with the central axis of the recycling bin. The connecting barrel has openings at both ends in the vertical direction. The filter plate is connected to the bottom of the connecting barrel. The recycling bin has a connection port for the connecting barrel to pass through. The connecting barrel passes through and is slidably connected to the recycling bin in the horizontal direction. The connecting barrel is locked to the recycling bin by a locking device.

[0016] By adopting the above technical solution, impurities are prone to accumulate in the connecting bucket after long-term use. When there are impurities in the connecting bucket, the lifting component drives the connecting rod to move downward in the vertical direction, so that the connecting rod is away from the mounting cover and filter plate. The locking component unlocks the connecting bucket from the recycling bucket, and the connecting bucket moves horizontally so that the connecting bucket passes through the connecting port horizontally, so that the connecting bucket is away from the recycling bucket, thereby facilitating the cleaning and replacement of the connecting bucket.

[0017] Optionally, a positioning ring is connected to the bottom of the mounting cover, the central axis of the positioning ring is collinear with the central axis of the mounting cover, and a positioning groove is provided on the top of the filter plate for the positioning ring to be embedded.

[0018] By adopting the above technical solution, when installing the scraper, the positioning ring is embedded in the positioning groove, which makes the mounting cover stably connected to the top of the filter plate and facilitates the insertion of the connecting rod into the mounting cover.

[0019] Optionally, a circumferential protrusion is connected to the outer circumference of the positioning ring, and a groove is formed on the inner wall of the positioning groove. The circumferential direction of the groove is consistent with that of the positioning ring. The circumferential protrusion is embedded in the groove and is slidably connected to the groove along the circumferential direction of the positioning ring. The positioning block and the filter plate are engaged by the circumferential protrusion and the groove.

[0020] By adopting the above technical solution, the positioning block and the filter plate are engaged by the annular protrusion and the groove, so that the mounting cover is stably connected to the top of the filter plate, and the connecting rod is minimized from pushing the mounting cover to move when it is embedded in the mounting cover, making it easier for the mounting cover to be installed on the top of the connecting rod.

[0021] Optionally, a sealing layer is connected to the inner wall of the connection port, the sealing layer being in contact with the connection barrel, and the sealing layer being used to seal the gap between the connection barrel and the inner wall of the connection port.

[0022] By adopting the above technical solution and adding a sealing layer, wastewater can be prevented from being discharged out of the recycling bin through the gap between the connection port and the connection bucket, thereby reducing wastewater waste.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Wastewater enters the recycling tank through the filter plate. The filter plate filters the wastewater, thereby reducing impurities in the wastewater. When the wastewater passes through the filter plate, the rotating component drives the scraper to rotate, which pushes the impurities adhering to the top of the filter plate, thus avoiding the impurities from clogging the filter plate and improving the wastewater filtration efficiency.

[0025] 2. The first motor drives the rotating rod to rotate, causing the mounting cover and scraper to rotate with the rotating rod. This causes the scraper to push the impurities on the top of the filter plate, thereby reducing the clogging of the filter plate by impurities. The mounting cover is detachably connected to the rotating rod through a locking assembly, which facilitates cleaning and replacement of the scraper.

[0026] 3. With prolonged use, impurities may accumulate inside the connecting bucket. When impurities are present, the lifting mechanism moves the connecting rod vertically downwards, moving it away from the mounting cover and filter plate. The locking mechanism then unlocks the connecting bucket from the recycling bucket. The connecting bucket is then moved horizontally through the connection port, moving it away from the recycling bucket. This facilitates cleaning and replacement of the connecting bucket.

[0035] Reference Figure 1 and Figure 3 The recycling bin 100 is connected to a rotating assembly 400, which drives the scraper 300 to rotate. When wastewater passes through the filter plate 200, the rotating assembly 400 drives the scraper 300 to rotate, and the scraper 300 pushes away impurities on the top of the filter plate 200, thereby minimizing the possibility of impurities clogging the filter plate 200 and improving the efficiency of wastewater passing through the filter plate 200.

The sealing plate 510 is an arc-shaped plate, and its length direction is consistent with the circumference of the connecting bin. The concave arc side of the sealing plate 510 contacts the outer wall of the recycling bin 100. A locking element is connected to the sealing plate 510 to lock the sealing plate 510 in the recycling bin. The locking element is a bolt that passes radially through the sealing plate 510 and is threaded into the recycling bin 100. A handle 511 is connected to the side of the sealing plate 510 away from the connecting bin 500.

[0039] When there are impurities in the connecting bucket 500, the sealing plate 510 is removed from the outer wall of the recycling bucket 100 by bolts and slidably connected to the connecting port 130 along the radial direction of the recycling bucket 100, so as to remove the connecting bucket 500 from the recycling bucket 100, thereby facilitating the cleaning and replacement of the filter plate 200.

One end of the scraper 300 along its length is connected to the outer circumferential wall of the mounting cover 630, and the other end of the scraper 300 contacts the inner wall of the recycling bin 100. The first motor 410 drives the sleeve rod 620 to rotate, causing the connecting rod 610 to rotate with the sleeve rod 620. The mounting cover 630 rotates with the connecting rod 610, thereby driving the scraper 300 to rotate. This causes the scraper 300 to push away impurities on the top of the filter plate 200, reducing the possibility of impurities clogging the filter plate 200.

[0043] Reference Figure 3 and Figure 5The bottom of the mounting cover 630 is connected to a positioning ring 631. The central axis of the positioning ring 631 is collinear with the central axis of the mounting cover 630.

[0047] When the connecting bucket 500 is disassembled, the first cylinder 160 drives the connecting rod 610 to move downward in the vertical direction, so that the locking block 720 is away from the locking groove 633, thereby facilitating the movement of the connecting bucket 500 and its removal from the recycling bucket 100.

[0048] The implementation principle of one embodiment of this application is as follows: the water pump 111 pumps the wastewater in the washing machine body into the recycling tank 100. The wastewater passes through the filter plate 200, thereby reducing impurities in the wastewater. The filtered wastewater is stored in the recycling tank 100 and introduced to the next processing process through the outlet pipe 120. When the wastewater passes through the filter plate 200, the first motor 410 drives the second gear 430 to rotate, the second gear 430 drives the first gear 420 to rotate, and the rotating rod 600 follows the first gear 420 to rotate.
