Description

Technical Field

[0001] This invention belongs to the field of home appliances, specifically relating to a filter-type detergent dispensing component and washing equipment. Background Technology

[0002] Microfibers are fiber particles less than 5 mm in length. In 2011, Browne et al. first proposed that household washing of synthetic fiber clothing is a significant source of microfibers, and their experiments showed that a single wash of a garment can release more than 1,900 fibers, raising awareness of the sources of microfiber release from household washing. In 2017, the IUCN (International Union for Conservation of Nature) published a research report on primary microfibers released into the global ocean. The report showed that washing synthetic fabrics can release 35% of primary microfibers into the ocean.

[0003] In 2013, the number of household washing machines worldwide reached 840 million. With the increase in population, the global consumption of synthetic fiber textiles is gradually increasing, and the number of washing machines and the frequency of washing will also gradually increase. It is urgent to study how to collect the synthetic microfibers released during the washing process.

[0004] Chinese Patent Application No. CN201780096297.8 discloses a washing machine having a drum, a water collection tank below the drum, and a water circulation system. The water circulation system includes a removable drawer for introducing detergent or additives. The water circulation system is fluidly connected to a detection device for detecting microfibers or contaminants in the water, a circulation pump, and pipes for circulating the water. Its operation method includes the following steps: circulating a certain amount of water in the circulation system and delivering it to the detection device for analysis; and analyzing the water in the detection device. Depending on the result of the analysis, a filtration process utilizing a filtration device is activated to filter out microfibers from the water. The filtered microfibers can be collected and then easily removed from the washing machine.

[0005] Although the filtration device in the above solution can be used to filter microfibers and circulate washing water, the filtration device cannot self-clean and remove the debris accumulated in the filtration device.

[0006] In view of the above-mentioned technical deficiencies, this invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a filter-type detergent dispensing component that can both filter microfibers to circulate washing water and clean the filter module.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] A filter-type detergent dispensing assembly includes a drawer and a housing for receiving the drawer, the drawer comprising,

[0010] Detergent compartment, used to hold detergent;

[0011] A filter module, installed on the drawer, is used to filter out debris;

[0012] The self-cleaning module is connected to the filter module and is used to clean the filter module.

[0013] By adopting the above solution, the detergent dispensing component can not only contain detergent and add detergent to the device to be added; it can also filter and circulate the washing water, integrating the detergent box and the filter module into one unit, reducing the space occupied by the filter module; it can also clean the filter module through a self-cleaning module to prevent the filter module from being blocked and affecting the filtration effect.

[0014] Furthermore, the filtering module includes,

[0015] The housing is disposed inside the drawer, and an internal cavity is formed therein;

[0016] The filter section is disposed within the housing;

[0017] The first water inlet is located on the casing;

[0018] The first water outlet is provided on the housing, and the water inlet is located on the different side of the filter section from the water outlet of the first water inlet.

[0019] The first valve body is installed on the first water outlet and is used to control the opening and closing of the water passage of the first water outlet.

[0020] Preferably, the first water inlet and the first water outlet are respectively disposed on two opposite shell walls of the shell.

[0021] By adopting the above scheme, the filtration unit can filter the washing water that enters the chamber through the first water inlet, and the first valve body can control the opening and closing of the water path of the first water outlet, and can select whether to filter the washing water as needed.

[0022] Furthermore, the self-cleaning module includes,

[0023] A second water inlet is provided on the housing for introducing tap water into the chamber from a different orientation than the water to be filtered through the filter section.

[0024] The second water outlet is provided on the housing, with the water inlet located on the different side of the filter section from the water outlet of the second water inlet, and connecting the chamber and the receiving section, for passing the discharged tap water into the receiving section;

[0025] The collection section, located downstream of the filter section, is used to collect the debris carried on the discharged tap water that has been removed from the filter module.

[0026] The second valve body is installed on the second water outlet and is used to control the opening and closing of the water passage in the second water outlet.

[0027] Preferably, the water inlet end of the second water inlet and the water inlet end of the first water inlet are located on the same side of the housing;

[0028] Preferably, the water inlet end of the second water outlet and the water outlet end of the first water inlet are located on the same side of the housing.

[0029] By adopting the above solution, the self-cleaning module can rinse the filter module in the opposite direction to the direction of the filtered debris. The tap water eventually enters the second outlet from the side where the filtered water enters the filter section and is discharged, thus cleaning the filter module. In addition, the collection section can collect the cleaned debris, so it is only necessary to clean the collection section periodically to remove the debris. The water inlet ends of the two water inlets are located at the same end of the shell, which simplifies the water inlet pipeline and facilitates water intake. The water inlet end of the second water outlet is located on the same side of the shell as the water outlet end of the first water inlet, which simplifies the water flow path.

[0030] Furthermore, the self-cleaning module also includes a scraping part disposed inside the housing, which moves under force to scrape away at least the debris on the filter part.

[0031] By adopting the above solution, the scraping part scrapes the filter part, which can prevent the debris stuck in the filter part from being easily washed away, thereby improving the cleaning effect of the filter part.

[0032] Furthermore, the filter section is a hollow columnar structure with through holes on its outer wall, and the scraping section is disposed in the inner cavity formed by the filter section and contacts the inner wall of the filter section;

[0033] Preferably, the filter section has an opening at one end facing the first water inlet section for allowing water to be filtered to pass into the inner cavity through the opening;

[0034] Preferably, the scraping part is provided in multiple parts;

[0035] Preferably, the scraping part has a mesh-like structure, with both ends movably abutting against the inner wall of the filtering part.

[0036] By adopting the above scheme, the hollow columnar structure with through holes on the outer wall can increase the area of ​​the filter section, and the water to be washed can be completely passed into the inner cavity of the filter section from one end for filtration, thereby ensuring the filtration effect; since most of the impurities accumulate in the inner cavity after filtration, setting multiple scraping parts in the inner cavity can improve the scraping efficiency.

[0037] Furthermore, a gap is left between the peripheral wall of at least one side of the filter section and / or the end of the filter section away from the first water inlet section and the inner wall of the housing, and the water outlet end of the second water outlet section is disposed in the gap;

[0038] Preferably, the water outlet of the second water outlet is located on the side near the water inlet of the filter section.

[0039] By adopting the above scheme, tap water can pass through the filter from multiple points outside the filter to backwash the filter and ensure the cleaning effect. The outlet of the second water outlet is set on the side near the water inlet of the filter, which increases the flow path of the tap water and thus increases the contact area with the filter, thereby improving the cleaning effect.

[0040] Furthermore, the filter section includes,

[0041] The filter body is used to filter out impurities;

[0042] The limiting unit, having a perforated structure, is disposed on the filter body to prevent the filter body from deforming under force.

[0043] Preferably, the filter body is made of an ultrafiltration membrane and / or a nanofiltration membrane and / or graphene material;

[0044] Preferably, the limiting unit includes,

[0045] The first fixing frame is disposed on the side of the filter body facing the first water inlet, and can fix the inner wall of the housing and the filter part.

[0046] The second fixing frame is disposed on the side of the filter body away from the first fixing frame, and the scraping part is fixedly connected to the second fixing frame.

[0047] By adopting the above solution, the limiting unit can prevent the filter body from deforming under water pressure, which would cause the filter pores to enlarge and become unable to filter fine microfibers, thus reducing the filtration effect. At the same time, it can still perform the filtration function without hindering the filtration of impurities. Ultrafiltration membranes, nanofiltration membranes, graphene materials and other materials all have microporous structures, which can filter microfibers and other tiny impurities, achieving the effect of filtering and collecting microfibers. In addition, the fixing frame structure of the limiting unit not only limits the deformation of the filter body, but also fixes and connects the shell and the filter part, and installs the scraping part.

[0048] Furthermore, a pressure detection device is also provided inside the housing, located near the filter section, for detecting water pressure.

[0049] By adopting the above scheme, the pressure detection device can detect the water pressure near the filter section. When the detected water pressure is higher than the set value, it can be considered that too much debris has accumulated in the filter section or the pore structure on the filter section is blocked, and it needs to be cleaned.

[0050] Another object of the present invention is to provide a washing device equipped with the above-mentioned filter-type detergent dispensing component.

[0051] Furthermore, including,

[0052] outer cylinder;

[0053] A drainage assembly, connected to the outer drum, is used to drain water from the outer drum to the outside of the machine body or to introduce it into the filter-type detergent dispensing assembly;

[0054] The liquid inlet pipe connects the housing and the outer cylinder, and is used to introduce liquid from the detergent dispensing component into the outer cylinder;

[0055] The judgment module is at least used to determine whether the filter module is clogged based on the detected water pressure.

[0056] The control module is used at least to control the state of the drainage component and the working state of the filter module and the self-cleaning module based on the washing program and the clogging status of the filter module as determined by the judgment module.

[0057] Preferably, the drainage assembly includes,

[0058] The first drain pipe is connected to the outer cylinder and is used to drain the water in the outer cylinder outward.

[0059] The three-way valve has its inlet end connected to the first drain pipe.

[0060] The second drain pipe is connected to one of the outlet ends of the three-way valve and is used to drain the water in the first drain pipe from the machine body.

[0061] The circulating water pipe has its inlet end connected to the other outlet end of the three-way valve, and its outlet end is detachably connected to the first inlet part. It is used to pass the water in the first drain pipe into the detergent dispensing component for filtration and circulation.

[0062] The control module can control the opening and closing state of the three-way valve.

[0063] By adopting the above scheme, the water discharged from the outer drum can be filtered through the detergent dispensing component before being introduced into the outer drum, depending on the actual situation. This achieves the purpose of circulating the washing water and preventing microfibers from ultimately entering the soil and causing environmental harm. Alternatively, the water can be discharged directly, which can make full use of the water inlet function of the detergent box and reduce the space occupied by the filtration module.

[0064] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0065] 1. The detergent dispensing component can not only hold detergent and add detergent to the device to be added; it can also filter and circulate the washing water, integrating the detergent box and the filter module into one unit, reducing the space occupied by the filter module; it can also clean the filter module through a self-cleaning module to prevent the filter module from being blocked and affecting the filtration effect.

[0066] 2. The filtration module and self-cleaning module each have valve bodies, which can control the filtration function and self-cleaning function respectively; the direction of the filtered water through the filtration section is opposite to the direction of the tap water through the filtration section, which facilitates the rinsing of the debris attached to the filtration section and its removal by the tap water; the collection section can collect the cleaned debris, so it is only necessary to clean the collection section periodically to remove the debris; the water inlet ends of the two water inlets are located at the same end of the housing, which simplifies the water inlet pipeline and facilitates water intake; the water inlet end of the second water outlet is located on the same side of the housing as the water outlet end of the first water inlet, which simplifies the water flow path.

[0067] 3. The scraping section can scrape away debris that is difficult to wash away and stuck in the filter section, thereby improving the cleaning effect of the filter section.

[0068] 4. The hollow columnar structure with through holes on the outer wall can increase the area of ​​the filter section, and the water to be washed can be completely passed into the inner cavity of the filter section from one end for filtration, thus ensuring the filtration effect; since most of the impurities accumulate in the inner cavity after filtration, multiple scraping parts are set in the inner cavity to improve scraping efficiency.

[0069] 5. There is a gap between the end of the filter section through which the non-filtered water passes and the housing, which allows tap water to backwash the filter section and ensure a clean effect; the limiting unit can prevent the filter body from deforming under water pressure, which would cause the filter pores to become larger and unable to filter fine microfibers, thus reducing the filtration effect, while also playing a filtration role and not hindering the filtration of impurities; materials such as ultrafiltration membranes, nanofiltration membranes, and graphene materials all have microporous structures, which can filter microfibers and other tiny impurities, achieving the effect of filtering and collecting microfibers.

[0070] 6. The pressure detection device can detect the water pressure near the filter section. When the detected water pressure is higher than the set value, it can be assumed that there is too much debris in the filter section or that the pore structure on the filter section is blocked, and cleaning is required. The control module can select and control the opening and closing status of the three-way valve and the water flow status of the two inlet and two outlet sections according to the relevant program and detection data, thereby controlling the water discharged from the outer cylinder to be filtered before being introduced into the outer cylinder and to clean the filter module, or to choose to discharge it directly.

[0086] like Figures 1 to 6As shown, the present invention provides a filter-type detergent dispensing assembly, including a drawer 1 and a box 11 for accommodating the drawer 1. The drawer 1 includes a detergent chamber 2 for accommodating detergent; a filter module 3 disposed on the drawer 1 for filtering impurities; and a self-cleaning module 4 connected to the filter module 3 for cleaning the filter module 3.

[0087] like Figure 1 and Figure 6 As shown, the detergent chamber 2 is located at one end of drawer 1 near the drawer handle, and the filter module 3 and self-cleaning module 4 are located at the other end of drawer 1. The housing 1 is equipped with a tap water inlet pipe and a valve for controlling the flow of tap water into drawer 1. Drawer 1 has an inlet connecting the tap water inlet pipe and the detergent chamber 2, for supplying water to the detergent chamber 2 and mixing the water with the detergent in the chamber before discharging it from the outlet on drawer 1.

[0088] The detergent dispensing component of the present invention can not only contain detergent and add detergent to the device to which detergent is to be added; it can also integrate the detergent box and the filter module 3 into one unit, so as to filter and circulate the washing water through the box component, thereby reducing the space occupied by the filter module 3; it can also clean the filter module 3 through the self-cleaning module 4, so as to prevent the filter module 3 from being blocked and affecting the filtration effect.

[0089] like Figure 2 As shown, the filter module 3 includes: a housing 31 disposed inside the drawer 1, forming a chamber inside; a filter section 32 disposed inside the housing 31 for filtering water to be filtered that enters the chamber; a first water inlet section 33 disposed on the housing 31 for introducing water to be filtered into the chamber; a first water outlet section 34 disposed on the housing 31, with its inlet end located on a different side from the outlet end of the first water inlet section 33, for discharging the filtered water; and a first valve body 35 disposed on the first water outlet section 34 for controlling the opening and closing of the water passage of the first water outlet section 34.

[0090] In one embodiment, the first water inlet 33 includes a first water inlet connector penetrating the housing 31. Preferably, the first water inlet connector penetrates the box wall on one side of the drawer 1 and is used to connect to the device on which the detergent dispensing component is to be installed, allowing the water to be filtered to be introduced into the housing 31 through the first water inlet connector. The first water outlet 34 is an outlet penetrating the housing 31, which communicates with the drawer 1, allowing the filtered water to be discharged into the drawer 1 and discharged through the outlet on the drawer 1. The outlet on the drawer 1 for discharging detergent and the outlet for discharging filtered water may be the same outlet or different outlets; or the first water outlet 34 may be a pipe with both ends penetrating the housing 31 and the drawer 1 respectively, allowing the filtered water to be discharged directly from the drawer 1 through the pipe.

[0091] The filter section 32 is mounted on the inner wall of the housing 31. The first water inlet 33 is located on one side of the filter section 32, and the first water outlet 34 is located on the opposite side of the filter section 32 from the first water inlet 33. As a preferred embodiment, such as... Figure 2 As shown, the first water inlet 33 and the first water outlet 34 are respectively disposed on two opposite shell walls of the housing 31. Preferably, the filter section 32 is detachably connected to the inner wall of the housing 31.

[0092] The filter section 32 of the present invention can filter the washing water that enters the chamber through the first water inlet section 33, and the first valve body 35 can control the opening and closing of the water passage of the first water outlet section 34, and can select whether to filter the washing water as needed.

[0093] like Figure 2 and Figure 3 As shown, the self-cleaning module 4 includes: a second water inlet 43, disposed on the housing 31, for introducing tap water into the chamber from a direction different from the water to be filtered through the filter section 32; a second water outlet 44, disposed on the housing 31, with its inlet end located on a different side of the filter section 32 from the outlet end of the second water inlet 43, and communicating with the outlet end of the first water inlet 33, for discharging tap water from the side of the filter section 32 where the water to be filtered is introduced and into the receiving section 41; the receiving section 41, located downstream of the filter section 32, for collecting debris carried on the discharged tap water and removed from the filter module 3; and a second valve body 45, disposed on the second water outlet 44, for controlling the opening and closing of the water passage of the second water outlet 44.

[0094] like Figure 2 As shown, the storage section 41 includes a storage unit for filtering tap water discharged from the second water outlet section 44; a storage cavity, disposed inside the drawer 1, is formed by a partition disposed inside the drawer 1 and the inner wall of the drawer 1, for accommodating the storage unit; preferably, the storage unit is detachably disposed inside the storage cavity.

[0095] The storage unit can be a mesh storage bag or storage box with micropores. The water outlet of the second water outlet 44 is connected to the storage cavity and located inside the storage cavity, or connected to the water inlet of the storage cavity. Tap water from the storage part 41 flows out from the outlet on the drawer 1. The outlet on the drawer 1 for draining the tap water from the storage part 41 is the same outlet as the outlet for draining detergent and / or filtered water, or they are different outlets; or the tap water from the storage part 41 flows out from a pipe penetrating the drawer 1.

[0096] The water outlet of the storage section 41 and / or the water outlet of the first water outlet 34 are connected to the water inlet of the detergent chamber 2, and the storage section 41 and / or the first water outlet 34 drain water to the outside of the drawer 1 through the detergent chamber 2; or, the water outlet of the storage section 41, the water outlet of the first water outlet 34, and the water inlet of the detergent chamber 2 are each independent.

[0097] Furthermore, such as Figure 2 and Figure 3 As shown, the water inlet end of the second water inlet 43 and the water inlet end of the first water inlet 33 are located on the same side of the housing 31. Preferably, the water inlet end of the second water inlet 43 and the water inlet end of the first water inlet 33 are disposed on the shell wall of the housing 31 on the side away from the detergent chamber 2.

[0098] like Figure 2 and Figure 3 As shown, the second water inlet 43 includes a second water inlet connector 431 that penetrates one side of the shell wall of the housing 31; and a water inlet channel 432 that is connected to the outlet end of the second water inlet connector 431. The outlet end of the water inlet channel 432 extends to the filter section 32, avoiding the water to be washed, and enters one side of the filter section 32. Preferably, the second water inlet connector 431 penetrates one side of the drawer 1 and is used to connect to the device on which the washing box assembly is to be installed.

[0099] As one implementation method, such as Figure 2 and Figure 3As shown, the second water inlet connector 431 is disposed near the first water inlet portion 33. The water inlet channel 432 extends from its connection with the second water inlet connector 431 toward one side of the first water inlet portion 33 to a side wall near the housing 31 on the side where the second water inlet connector 431 is located, and then extends along this side wall to the side of the filter portion 32 where the water to be filtered enters. The first water inlet connector on the first water inlet portion 33 penetrates the water inlet channel 432 radially along the same side as the first water inlet portion 33. There is a gap between the outlet end of the first water inlet connector and the filter portion 32. This gap, together with the inner wall of the housing 31 and the outer wall of the water inlet channel 432 facing the first water inlet portion 33, forms a water inlet chamber for the water to be filtered. The water inlet chamber for the water to be filtered is connected to one side of the filter portion 32, so that the water to be filtered completely passes through the filter portion 32 from one side. The water inlet channel 432 bypasses the side of the filter section 32 through which the water to be filtered passes, and tap water is introduced into the filter section 32 from the side of the housing 31 near the detergent chamber 2. The water inlet chamber to be filtered is connected to the water inlet end of the second water outlet section 44.

[0100] As a preferred embodiment of the above solution, the inlet end of the second water outlet 44 and the outlet end of the first water inlet 33 are located on the same side wall of the housing 31, away from the outlet end of the first water inlet 33, and the inlet end of the second water inlet 43 is located between the outlet end of the first water inlet 33 and the inlet end of the second water outlet 44.

[0101] like Figure 2 and Figure 3 As shown, the water inlet end of the filter section 32 is connected to the inner wall of the housing 31 and the outer wall of the water inlet channel 432. The outer wall of the water inlet channel 432 is connected to the side of the water inlet end of the filter section 32 facing the water inlet end of the first water inlet section 33.

[0102] like Figure 2 and Figure 3 As shown, a mesh mounting plate 311 is provided on the side wall of the housing 31 where the outlet end of the second water inlet 43 is located. A gap exists between the mesh mounting plate 311 and the interior of the housing 31 on that side, and the outlet end of the second water inlet 43 communicates with this gap. The edge of the inlet end of the filter section 32 is connected to both the mesh mounting plate 311 and the inner wall of the housing 31.

[0103] The second water outlet 44 includes a second water outlet 441, which is disposed on the shell wall of the housing 31 on the same side as the first water inlet 33 and communicates with the first water inlet 33. The second valve body 45 is disposed on the second water outlet 441. A water outlet channel 442 is disposed against the outer wall of the housing 31 on the side opposite to the water outlet end of the second water inlet 43, extends to the receiving part 41, and connects the second water outlet 441 and the receiving part 41. The second water outlet 441 communicates with the water inlet chamber 36 to be filtered, which forms a drainage chamber for the tap water after cleaning the filter module 3.

[0104] The water inlet channel 432 and the water outlet channel 442 are formed by pipes installed on the shell 31, or by a sandwich of double shell walls partially provided on the shell 31.

[0105] As one implementation method, such as Figure 2 and Figure 3 As shown, the storage part 41 is disposed between the housing 31 and the detergent chamber 2.

[0106] The self-cleaning module 4 of the present invention can rinse the filter module 3 in the opposite direction to the direction of the filtered debris, thereby cleaning the filter module 3. In addition, the storage part 41 can collect the cleaned debris, so it is only necessary to clean the storage part 41 periodically to remove the debris. The water inlet ends of the two water inlets are located on the same side of the housing 31, which simplifies the water inlet pipeline and facilitates water intake.

[0107] The self-cleaning module 4 also includes a scraping part 42, which is disposed inside the housing 31 and moves under force to scrape away at least the debris on the filter part 32.

[0108] Furthermore, the scraping part 42 is disposed on the filter part 32, and the scraping part 42 is partially fixed on the filter part 32. After being subjected to force and moving, at least a part of the scraping part 42 contacts the filter part 32 to scrape the debris on the filter part 32.

[0109] In one embodiment, the scraping part 42 is provided on the side of the filter part 32 where the water to be filtered is introduced.

[0110] The scraping part 42 of the present invention scrapes the filter part 32, which can prevent the debris stuck in the filter part 32 from being easily washed away, thereby improving the cleaning effect of the filter part 32.

[0111] like Figure 2 and Figure 3 As shown, the filter section 32 is a hollow columnar structure with through holes on its outer wall. The scraping part 42 is disposed in the inner cavity formed by the filter section 32 and contacts the inner wall of the filter section 32. The filter section 32 is located near the water inlet end of the first water inlet section 33.

[0112] The scraping part 42 is disposed on the inner wall of the end of the filter part 32 away from the end into which the water to be filtered enters, and is fixedly connected to the filter part 32.

[0113] In one embodiment, the scraping part 42 has a mesh-like structure. The middle part of the scraping part 42 is fixedly connected to the middle part of the inner wall of one end of the filter part 32, and is disposed in close contact with the inner wall of the filter part 32. The two ends of the scraping part 42 respectively abut against the inner walls of the filter part 32 on the two sides near the fixed connection with the scraping part 42. The scraping part 42 has a deformation capacity, and after being deformed by force, the two ends move relative to the filter part 32 to scrape away debris.

[0114] The scraping part 42 can be fixedly connected to the filtering part 32 by screws or other connecting parts 5.

[0115] Alternatively, the shape of the scraping part 42 matches the shape of the inner peripheral wall of the filter part 32, and the outer periphery of the scraping part 42 moves into contact with the inner peripheral wall of the filter part 32.

[0116] Furthermore, such as Figure 4 As shown, multiple scraping portions 42 are provided, evenly distributed along the central axis of the filter section 32. The connecting member 5 is a connecting rod, one end of which is fixedly connected to the end of the filter section 32 away from the end into which the water to be filtered enters. The scraping portions 42 near the connecting rod and connected to the end of the filter section 32 are disposed against the end wall of the filter section 32. Each scraping portion 42 passes through the connecting rod and is fixedly connected to the connecting rod. This design increases the contact area between the scraping portions 42 and the filter section 32, facilitating the scraping of impurities on the filter section 32 and improving the cleaning efficiency of the filter section 32.

[0117] In one embodiment, the filter section 32 has an opening at one end facing the first water inlet 33, for allowing water to be filtered to enter the inner cavity through the opening. In this embodiment, the side of the filter section 32 where the water to be filtered enters can also be infinitely close to the side where the first water inlet 33 is located. Figure 5 As shown.

[0118] The filter section 32 of the present invention, which has a hollow columnar structure with through holes on its outer wall, can increase the contact area with impurities. The water to be washed can be completely introduced into the inner cavity of the filter section 32 from one side for filtration, thereby ensuring the filtration effect. Since most of the impurities accumulate in the inner cavity after filtration, multiple scraping sections 42 are set in the inner cavity to improve scraping efficiency.

[0119] A gap is left between the peripheral wall of at least one side of the filter section 32 and / or the end of the filter section 32 away from the first water inlet 33 and the inner wall of the housing 31. The water outlet end of the second water outlet 44 is disposed in the gap for passing tap water into the inner cavity to rinse and clean the filter section 32.

[0120] As one implementation method, such as Figures 2 to 5 As shown, gaps are left between the peripheral wall of the filter section 32 and the end of the filter section 32 away from the first water inlet 33 and the inner wall of the housing 31, forming an annular cavity. The water outlet end of the second water outlet 44 is located on the side of the filter section 32 near the water to be filtered. Tap water passes through the annular cavity from the peripheral wall of the filter section 32 and the end wall away from the first water inlet 33 into the inner cavity, rinsing and cleaning various parts of the filter section 32.

[0121] Furthermore, such as Figure 3 As shown, the filter section 32 includes a filter body 321 for filtering impurities; and a limiting unit 322, having a perforated structure, disposed on the filter body 321 to prevent deformation of the filter body 321 under force and limit the change of filter holes on the filter body 321. The limiting unit 322 is disposed in close contact with the filter body 321.

[0122] As one implementation, the filter body 321 is made of materials such as ultrafiltration membrane and / or nanofiltration membrane and / or graphene, or the filter body 321 is a filter screen and / or filter plate structure with micropores, which can be used to filter tiny impurities such as microfibers.

[0123] The limiting unit 322 is disposed on one side of the filter body 321 or covers the outer periphery of the filter body 321 to limit the deformation of the filter body 321 and prevent the filter pores on the filter body 321 from becoming larger.

[0124] The limiting unit 322 of the present invention can prevent the filter body 321 from being deformed under water pressure, which would cause the filter holes to become larger and unable to filter fine microfibers, thus reducing the filtration effect.

[0125] like Figure 3 As shown, the limiting unit 322 includes: a first fixing frame 3221, disposed at one end of the filter body 321 facing the first water inlet 33, which can fixably connect the inner wall of the housing 31 and the filter part 32; a second fixing frame 3222, disposed at one end of the filter body 321 away from the first fixing frame 3221, and the scraping part 42 is fixedly connected to the second fixing frame 3222; and a third fixing frame 3223, disposed on the peripheral wall of the filter part 32.

[0126] like Figure 3As shown, the first fixing frame 3221 is a perforated plate-like structure that covers or encloses the end of the filter body 321 facing the first water inlet 33. A gap is left between the outer peripheral wall of the filter body 321, the inner wall of the housing 31, and the mesh mounting plate 311. The outer peripheral end of the first fixing frame 3221 extends outwards to the inner wall of the housing 31 and the mesh mounting plate 311, and is fixedly connected to them. The extension of the first fixing frame 3221 does not have perforations. The outer wall of the outlet end of the second water inlet 43 is sealed to the side of the extension facing the inlet end of the first water inlet 33. The outlet end of the second water inlet 43 is located outside the peripheral wall of the filter body 32.

[0127] Alternatively, if the filter body 321 has an opening at one end where the water to be filtered is introduced, the first fixing bracket 3221 can also be provided on the outer periphery of the opening to form the extension without perforation.

[0128] The second fixing frame 3222 is a perforated plate structure that covers or wraps around the end of the filter body 321 opposite to the first fixing frame 3221. The connector 5 passes through both sides of the second fixing frame 3222 and the filter body 321 and is fixedly connected to the filter part 32.

[0129] The third fixing frame 3223 is a helical spring structure, which is sleeved on the inner and outer peripheral walls of the filter body 321.

[0130] In addition to limiting the deformation of the filter body, the limiting unit 322 of the present invention can also fix the connection between the housing 31 and the filter part 32, and install the scraping part 42.

[0131] like Figure 2 and Figure 5 As shown, a pressure detection device 6 is also provided inside the housing 31, located near the filter section 32, for detecting water pressure. The pressure detection device 6 is located on the filter section 32 and / or on the inner wall of the housing 31 and / or on the second water inlet section 43.

[0132] The pressure detection device 6 of the present invention can detect the water pressure near the filter section 32. When the water pressure is detected to be higher than the set value, it can be considered that too much debris has accumulated in the filter section 32 and needs to be cleaned.

[0133] Working principle: such as Figure 2As shown, when filtration is required, the first valve body 35 is in the open state and the second valve body 45 is in the closed state. Water to be filtered is introduced into the housing 31 through the first inlet 33. The water passes through the water inlet chamber 36 between the filter section 32 and the first inlet 33, reaching one side of the filter section 32. After being filtered by the filter body 321 and the first fixing frame 3221 on that side, the water enters the inner cavity of the filter section 32. After being filtered through the peripheral wall of the filter section 32 or the side wall opposite to the water inlet of the filter section 32, the water flows out and enters the annular cavity formed between the filter section 32 and the housing 31, finally exiting the housing 31 from the first outlet 34. Under the action of the water flow, the scraping part 42 adheres to the inner wall of the filter section 32, fixing the filter body 321 and preventing deformation during filtration, thus aiding in the filtration process.

[0134] like Figure 3 As shown, when the pressure detection device 6 detects that the pressure is greater than the set value, it is considered that a large amount of debris is attached to the filter section 32 or that it has been blocked, and the filter module 3 needs to be cleaned. At this time, the first valve body 35 is closed and the second valve body 45 is opened, and tap water is introduced into the annular cavity from the second water inlet 43. The water flows through the annular cavity from the outer periphery of the filter section 32 and the outside of the end away from the water inlet chamber 36 to be filtered into the inner cavity of the filter section 32. Under the action of water pressure, the scraping part 42 is deformed by force, and both ends move along the direction of water flow to scrape the debris on the inner wall of the filter section 32. The tap water carrying the debris is finally discharged from the second water outlet 44 connected to the water inlet chamber to be filtered, and the filter section 32 is backwashed. The rinsed tap water is discharged to the collection part 41, filtered by the collection part 41, and finally discharged from the drawer 1.

[0135] like Figure 7 and Figure 8 As shown, a washing device of the present invention having the above-mentioned filter-type detergent dispensing component includes an outer drum 7; a drain component 8, connected to the outer drum 7, for discharging water in the outer drum 7 to the outside of the machine body or into the filter-type detergent dispensing component; a liquid inlet pipe 10, connected to the housing 11 and the outer drum 7, for dispensing liquid from the detergent dispensing component into the outer drum 7; a judgment module, at least for judging whether the filter module 3 is blocked based on the detected water pressure; and a control module, at least for controlling the state of the drain component 8 and the working state of the filter module 3 and the self-cleaning module 4 based on the washing program and the blockage status of the filter module 3 judged by the judgment module.

[0136] The drainage assembly 8 includes: a first drain pipe 81 connected to the outer cylinder 7 for draining water from the outer cylinder 7; a three-way valve 84 with its inlet end connected to the first drain pipe 81; a second drain pipe 82 connected to one outlet end of the three-way valve 84 for draining water from the first drain pipe 81 into the machine body; and a circulating water pipe 83 with its inlet end connected to the other outlet end of the three-way valve 84 and its outlet end detachably connected to the first water inlet 33 for circulating water from the first drain pipe 81 into the detergent dispensing assembly for filtration. The control module can control the opening and closing state of the three-way valve 84 and the working state of the filter module 3 and the self-cleaning module 4 according to the washing program and the clogging status of the filter module as determined by the judgment module.

[0137] The box body 11 is fixedly installed on the outer wall of the outer cylinder 7. The outlet end of the circulating water pipe 83 is located on the box body 11 and matches the position of the inlet end of the first water inlet 33. It can be detachably connected to the first water inlet connector of the first water inlet 33.

[0138] The washing device also includes a tap water inlet pipe connected to the housing 11, which can be detachably connected to the second inlet connector 431 of the second water inlet section 43. Alternatively, the tap water inlet pipe includes a first inlet pipe, which is detachably connected to the second inlet connector 431 of the second water inlet section 43; and a second inlet pipe, which is detachably connected to the inlet of the detergent chamber 2.

[0139] In one implementation scheme, the first drain pipe 81, the second drain pipe 82, the circulating water pipe 83, and the three-way valve 84 are located on the same side of the washing equipment, near the back of the washing equipment.

[0140] A drainage pump 85 is installed on the first drainage pipe 81.

[0141] Furthermore, a detection device is also installed on the first drain pipe 81 to detect the content of microfibers and / or impurities in the washing water in the first drain pipe 81.

[0142] Working principle: such as Figure 7 and Figure 8As shown, when the content of microfibers and / or impurities in the first drain pipe 81 detected by the judgment module is higher than the set value, or the washing equipment is executing a program for washing fabrics with high microfiber content, the judgment result is sent to the control module. The control module controls the three-way valve 84 to open the valve leading to the circulating water pipe 83. After the washing water is filtered by the washing box assembly, it is fed into the outer drum 7 through the liquid inlet pipe 10 for recycling. When the content of microfibers and / or impurities in the first drain pipe 81 detected by the judgment module is not higher than the set value, or the washing equipment is executing a program for washing fabrics with low microfiber content, the judgment result is sent to the control module. The control module then controls the three-way valve 84 to open the valve leading to the second drain pipe 82, directly discharging the washing water out of the machine. When the pressure detected by the pressure detection device 6 is greater than the set value, the judgment result is sent to the control module. The control module then controls the opening of the tap water inlet pipe to supply water into the second water inlet 43 to clean the filter module 3.

[0143] The washing equipment of the present invention can, according to actual conditions, select to control the water discharged from the outer drum 7 to be filtered through the detergent dispensing component before being introduced into the outer drum 7, so as to achieve the function of circulating the washing water and preventing microfibers from eventually entering the soil and causing harm to the environment; or select to discharge directly, which can make full use of the water inlet function of the detergent box and reduce the space occupied by the filter module 3 and the self-cleaning module 4.

[0144] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
