Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of household electrical appliances, in particular to a micro-fiber filter and a washing machine. BACKGROUND

[0002] Micro-plastics and micro-fibers generally refer to fibers or particles with a size of less than 5mm, which are increasingly polluting the marine environment. Micro-plastics and micro-fibers have strong adsorption capacity of pollutants due to their small size and large specific surface area. Micro-plastics and micro-fibers are like the mounts of marine pollutants, and when micro-plastics and micro-fibers combine with marine pollutants, they are easily ingested by marine organisms during their wandering in the ocean, which directly endangers the marine ecosystem, and humans are at the top of the food chain, micro-plastics and micro-fibers can enter the human body through ecological circulation and pose a serious threat to human health.

[0003] According to the research of the Coastal Cities Ecological Impact Research Center of the University of Sydney, one of the main sources of micro-plastics and micro-fibers in the ocean is the wastewater discharged from washing machines. As the research points out, more than 1900 tiny fibers are washed away with each wash, and under the premise that washing machines are popular worldwide and the frequency of washing is generally high, how to avoid the discharge of micro-plastics has become a technical problem to be solved.

[0004] The existing micro-fiber filter module of the washing machine uses a single-stage filter module, and since the pore size of the filter screen can only be set to be the smallest, the size distribution of stains and micro-fibers is wide during the washing process, and the filter membrane will soon be blocked, thereby losing the function of filtering micro-fibers.

[0005] Therefore, the present application is proposed. SUMMARY

[0006] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art. The present application provides a micro-fiber filter capable of prolonging the service life.

[0007] The present application provides a washing machine having the above-mentioned micro-fiber filter.

[0008] To solve the above technical problems, the basic idea of the technical solution of the present application is as follows:

[0009] A micro-fiber filter, comprising,

[0010] a filter cylinder, having a water inlet and a water outlet at two ends respectively;

[0011] a filter screen, installed in the filter cylinder, arranged along the extension direction of the central axis of the filter cylinder;

[0012] a screw rod, one end of which is inserted into the filter cylinder along the axial direction of the filter cylinder;

[0013] Spiral blades are arranged on the outer periphery of the screw rod and have a gap with the filter screen;

[0014] Further comprising: a microfiber collecting device arranged at a position close to the water outlet of the filter cylinder;

[0015] The spiral direction of the spiral blade is the same as the flow direction of the water flow in the filter cylinder, which is used to scrape the microfibers on the filter screen into the microfiber collecting device.

[0016] In the above scheme, the rotation of the screw rod makes the spiral blade rotate and advance, scraping off the microfibers deposited on the filter screen, collecting the microfibers into the microfiber collecting device by the flow of the water flow, and prolonging the service life of the microfiber filter.

[0017] Further, the water inlet is arranged at the upper side wall of one end of the filter cylinder, and the water outlet is arranged at the lower side wall of the other end of the filter cylinder.

[0018] Further, the filter screen is in a cylindrical structure and is arranged circumferentially along the extension direction of the central axis of the filter cylinder, and the screw rod is inserted into the filter screen;

[0019] The gap between the spiral blade and the filter screen close to the upper side wall of the filter cylinder is greater than the gap between the spiral blade and the filter screen close to the lower side wall of the filter cylinder.

[0020] In the above scheme, by setting the gap between the spiral blade and the filter screen close to the upper side wall of the filter cylinder to be greater than the gap between the spiral blade and the filter screen close to the lower side wall of the filter cylinder, a larger space can be provided for the flow of the water flow; and with the rotation and advancement of the spiral blade, the microfiber deposition layer attached to the lower filter screen can be stirred and rolled into the upper area of the filter cylinder, which not only dilutes the concentration of the microfibers, delays the deposition of the microfibers on the lower filter screen, and makes the microfibers more evenly distributed; but also avoids that the gap between the spiral blade and the filter screen close to the upper side wall of the filter cylinder is too small, which causes a larger resistance, making the water flow at the water inlet of the filter cylinder turbulent, causing the microfibers to quickly deposit at the water inlet, and affecting the service life of the microfiber filter.

[0021] Further, the part of the filter screen close to the upper side wall of the filter cylinder is arranged open along the extension direction of the central axis of the filter cylinder;

[0022] The gap between the spiral blade and the upper side wall of the filter cylinder is greater than the gap between the spiral blade and the filter screen close to the lower side wall of the filter cylinder.

[0023] In the above scheme, the filter screen is arranged in a semi-cylindrical shape, and the part of the filter screen close to the upper side wall of the filter cylinder is arranged open along the extension direction of the central axis of the filter cylinder, which can provide a larger flow space for the upper region of the filter cylinder, and better dilute the concentration of microfibers, and delay the deposition of microfibers on the lower filter screen.

[0024] Further, the part of the filter screen close to the water inlet of the upper side wall of the filter cylinder is arranged open along the extension direction of the central axis of the filter cylinder.

[0025] In the above scheme, the part of the filter screen close to the water inlet of the upper side wall of the filter cylinder is arranged open along the extension direction of the central axis of the filter cylinder, which avoids the microfibers adhering to the water inlet of the filter screen in the upper region, and causes the deposition of microfibers.

[0026] Further, the drive motor is arranged outside the filter cylinder and connected to the other end of the screw rod to drive the rotation of the screw rod.

[0027] Further, the filter screen is made of wear-resistant material; preferably, the filter screen is made of stainless steel material.

[0028] Further, the microfiber collecting device further comprises a filter bag arranged detachably in the microfiber collecting device.

[0029] Further, the microfiber collecting device further comprises a filter bag arranged detachably in the microfiber collecting device.

[0030] A washing machine has the microfiber filter as described above.

[0031] Further, the washing machine comprises,

[0032] Further, the washing machine comprises,

[0033] After adopting the above technical scheme, the present application has the following beneficial effects compared with the prior art:

[0034] The microfiber filter provided by the present application can rotate and push the spiral blade by the rotation of the screw rod, scrape off the microfibers deposited on the filter screen, collect the microfibers into the microfiber collecting device by the flow of water, and prolong the service life of the microfiber filter.

[0035] The microfiber filter provided by this invention provides a larger flow space for incoming water by setting the gap between the spiral blades and the filter screen near the upper side wall of the filter cylinder to be larger than the gap between the spiral blades and the filter screen near the lower side wall of the filter cylinder. Furthermore, as the spiral blades rotate, they agitate the microfiber deposits attached to the lower filter screen, causing them to tumble to the upper region of the filter cylinder. This not only dilutes the concentration of microfibers and slows down their deposition on the lower filter screen, resulting in a more uniform distribution of microfibers, but also avoids the situation where the gap between the spiral blades and the filter screen near the upper side wall of the filter cylinder is too small, leading to greater resistance and turbulent water flow at the inlet of the filter cylinder, causing microfibers to quickly deposit at the inlet and affecting the service life of the microfiber filter.

[0036] The microfiber filter provided by the present invention has the portion of the filter screen near the upper side wall of the filter cylinder open along the extension direction of the central axis of the filter cylinder, which can provide a larger flow space in the upper region of the filter cylinder, better dilute the concentration of microfibers, and delay the deposition of microfibers on the lower filter screen.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0049] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0050] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise explicitly specified and limited.

[0051] As Figures 1 to 6As shown, the present application provides a micro-fiber filter, comprising, a filter cylinder 121, having a water inlet 123 and a water outlet 124 at two ends respectively; a filter screen 122, installed in the filter cylinder, arranged along the extension direction of the central axis of the filter cylinder; a screw rod 125, one end of which is inserted into the filter cylinder 121 along the axial direction of the filter cylinder 121; a helical blade 126, arranged on the outer periphery of the screw rod 125, leaving a gap 130 between the helical blade and the filter screen 122; further comprising: a micro-fiber collecting device 127, arranged at the position of the filter cylinder 121 close to the water outlet 124; the helical blade 126 rotates in the same direction as the flow direction of the water flow in the filter cylinder 121, for scraping the micro-fiber on the filter screen 122 into the micro-fiber collecting device 127.

[0052] In the above scheme, the rotation of the screw rod 125 makes the helical blade 126 rotate and advance, scraping off the micro-fiber deposited on the filter screen 122, collecting the micro-fiber into the micro-fiber collecting device 127 by means of the flow of the water flow, prolonging the service life of the micro-fiber filter 12.

[0053] In some embodiments, as shown in Figure 2 and Figure 3 The water inlet 123 is arranged at the upper side wall 128 of one end of the filter cylinder, and the water outlet 124 is arranged at the lower side wall 129 of the other end of the filter cylinder 121.

[0054] By arranging the water inlet 123 and the water outlet 124 at the two ends of the filter cylinder 121 respectively, the flow path of the water flow can be prolonged. The screw rod 125 can rotate clockwise, so that the helical blade 126 rotates in the same direction as the flow direction of the water flow in the filter cylinder 121, to scrape the micro-fiber on the filter screen 122 into the micro-fiber collecting device 127. The present application can improve the collection efficiency of micro-fiber by means of the flow of the water flow.

[0055] In some embodiments, the filter screen 122 is in a cylindrical structure, arranged circumferentially along the extension direction of the central axis of the filter cylinder 121, and the screw rod 125 is inserted into the filter screen 122; the gap 130 between the helical blade and the filter screen 122 close to the upper side wall 128 of the filter cylinder 121 is greater than the gap 130 between the helical blade and the filter screen 122 close to the lower side wall 129 of the filter cylinder 121.

[0056] As shown in Figure 3 The water inlet is in communication with the inside of the filter screen, and after the water flow flows into the filter screen 122 from the water inlet 123 for filtration, it flows out from the water outlet 124 in the direction indicated by the arrow.

[0057] By setting the gap 130 between the spiral blade and the filter screen 122 close to the upper side wall 128 of the filter cylinder 121 to be larger than the gap 130 between the spiral blade and the filter screen 122 close to the lower side wall 129 of the filter cylinder 121, a larger space can be provided for the flow of the water inlet flow; and with the rotation of the spiral blade, the microfiber deposition layer attached to the lower filter screen 122 can be stirred to roll into the upper area of the filter cylinder 121, not only diluting the concentration of microfibers and delaying the deposition of microfibers on the lower filter screen 122, but also making the distribution of microfibers more uniform; and avoiding the gap 130 between the spiral blade and the filter screen 122 close to the upper side wall 128 of the filter cylinder 121 being too small, which causes a larger resistance, making the water flow at the water inlet 123 of the filter cylinder 121 turbulent, causing microfibers to quickly deposit at the water inlet 123, affecting the service life of the microfiber filter 12.

[0058] It can be understood that a water drainage channel is provided between the filter screen 122 close to the lower side wall 129 of the filter cylinder 121 and the lower side wall 129 of the filter cylinder 121. The filtered water flows out of the water outlet through the water drainage channel.

[0059] In some embodiments, the portion of the filter screen 122 close to the upper side wall 128 of the filter cylinder 121 is open in the extension direction of the central axis of the filter cylinder 122.

[0060] The gap 130 between the spiral blade and the upper side wall 128 of the filter cylinder 121 is larger than the gap 130 between the spiral blade and the filter screen 122 close to the lower side wall 129 of the filter cylinder 121.

[0061] In the above scheme, as shown in Figure 2 and Figure 6 The filter screen is arranged in a semi-cylindrical shape, and the portion of the filter screen close to the upper side wall of the filter cylinder is open in the extension direction of the central axis of the filter cylinder, which can provide a larger flow space for the upper area of the filter cylinder, better dilute the concentration of microfibers, and delay the deposition of microfibers on the lower filter screen.

[0062] In some embodiments, the portion of the filter screen 122 close to the water inlet 123 of the upper side wall 128 of the filter cylinder 121 is open in the extension direction of the central axis of the filter cylinder 121.

[0063] In the above scheme, the portion of the filter screen close to the water inlet of the upper side wall of the filter cylinder is open in the extension direction of the central axis of the filter cylinder, which avoids the deposition of microfibers.

[0064] As shown in Figures 4 to 6 The filter cylinder 121 can be in the shape of a cuboid or a cylinder, or can be in other shapes such as a cup, a prism, a parallelepiped or any other box-like structure.

[0065] In some embodiments, a driving motor 131 is arranged outside the filter cylinder 121 and is connected to the other end of the screw rod 125 to drive the screw rod 125 to rotate.

[0066] In some embodiments, the microfiber filter 12 further comprises a sensor arranged in the filter cylinder 121 to detect the content of microfibers on the filter screen 122.

[0067] A controller is electrically connected to the sensor and the driving motor 131 to control the operation of the driving motor 131.

[0068] In the above scheme, when the sensor detects that there are more microfibers in the microfiber filter 12, the controller controls the driving motor 131 to start operating, at which time the screw rod 125 rotates in the clockwise direction, so that the direction of rotation of the helical blade 126 is the same as the flow direction of the water flow in the filter cylinder 121, so as to scrape the microfibers on the filter screen 122 into the microfiber collection device 127. When the sensor detects that there are fewer microfibers in the microfiber filter 12, the controller controls the driving motor 131 to stop operating. It can be understood that the driving motor 131 can rotate intermittently.

[0069] It can be understood that the sensor can be a pressure sensor, an optical sensor, a turbidity sensor, a color change indicating sensor, a sediment analysis sensor, a flux sensor, an infrared sensor or other sensors, or any combination thereof.

[0070] In some embodiments, the filter screen 122 is made of wear-resistant material; preferably, the filter screen 122 is made of stainless steel material.

[0071] It can be understood that the filter screen 122 can also be made of other wear-resistant materials such as manganese steel alloy and silicon carbide material.

[0072] In some embodiments, the microfiber filter 12 further comprises a filter bag 129,

[0073] The filter bag 129 is detachably arranged in the microfiber collection device 127.

[0074] The filter bag 129 can be circumferentially arranged on the inner side wall of the microfiber collection device 127. When the microfibers in the filter bag 129 accumulate more, the filter screen 122 can be replaced, which is convenient for the user to clean directly.

[0075] The present application provides a washing machine 1 with the microfiber filter 12 as described above.

[0076] Further, the washing machine 1 comprises,

[0077] A housing 10 is provided with a front panel, and a mounting opening 11 is formed on the front panel. The microfiber collecting device 127 is detachably arranged at a position corresponding to the microfiber filter 12 and the mounting opening 11.

[0078] Of course, a corresponding door cover can also be arranged at the mounting opening 11 on the front panel. The user can open the door cover to take out the microfiber filter 12 or the filter bag in the microfiber filtering device for cleaning.

[0079] The above description is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and any simple modification, equivalent change and modification of the above-mentioned embodiment, which does not depart from the technical solution of the present application, are still within the scope of the present application.
