Description

TECHNICAL FIELD

[0001] The present application relates to the field of laundry treating apparatus, and in particular to a filter assembly and a laundry treating apparatus having the same. BACKGROUND

[0002] In the prior art, a filter assembly is usually arranged in the drainage passage of the laundry treating apparatus to filter the impurities, lint and undissolved detergent generated in the laundry washing process so as to avoid clogging the drainage passage or directly discharging into the environment to cause pollution. However, such filter assembly usually only simply uses a filter screen to filter the discharged sewage, which cannot have a beneficial effect on the water saving requirement in the laundry washing process. Moreover, in the process of filtering the washing water, the filter screen of the filter assembly will reduce the flow rate of the water flow, especially the filter screen with lint and impurities will further aggravate the negative effect, resulting in that the flow rate of the water flow is slowed down when passing through the filter, and the filtering efficiency and capacity are reduced, and the sewage and the lint and impurities therein which are not fully filtered will be directly discharged into the external environment, which still causes pollution to the environment.

[0003] In the related art, the filter assembly of the washing machine is provided with a filter cavity, and the cross-sectional area of the passage communicating with the filter cavity does not change, without considering how to utilize the change of the cross-sectional area to improve the filtering effect of the filter cavity. Moreover, in some schemes, the filter assembly is simply arranged in the detergent box to filter the impurities in the water flow in which the detergent is dissolved. In such schemes, the impurities may block the filter holes of the filter assembly, further resulting in that the flow rate of the filtered water flow is small, which cannot be used for spraying or flushing the laundry and the washing tub. SUMMARY

[0004] The present application aims to at least solve one of the problems existing in the prior art. To this end, one object of the present application is to provide a filter assembly, which is provided with an outer shell and an inner shell, the outer shell and the inner shell defining a first chamber and a second chamber, and a filter member is arranged on the inner shell. After a period of filtering, impurities are deposited on the filter member, the filtering speed is reduced, but at this time, the water pressure in the first chamber is also increased, so that the cleaning water in the first chamber maintains the filtering efficiency.

[0005] The present application also provides a laundry treating apparatus having the above filter assembly.

[0006] The filter assembly according to the present application comprises an outer shell, a closed containing cavity is formed in the outer shell, a filter assembly inlet and a filter assembly outlet are arranged on the outer shell; an inner shell is arranged in the containing cavity and divides the containing cavity into a first chamber and a second chamber, wherein the first chamber communicates with the filter inlet, and the second chamber communicates with the filter outlet.

[0007] According to the filter assembly for a garment processing device of the present invention, by providing an outer shell and an inner shell, the outer shell and the inner shell define a first chamber and a second chamber. After a period of filtration, impurities accumulate on the filter element, reducing the filtration rate. However, at this time, the water pressure in the first chamber also increases, maintaining the filtration efficiency of the washing water in the first chamber. According to one embodiment of the present invention, a connecting hole is provided on the outer periphery of the inner shell, and a filter element is provided on the connecting hole.

[0008] According to one embodiment of the present invention, a manifold cavity communicating with the second chamber and the filter outlet is further formed inside the housing.

[0009] According to one embodiment of the present invention, a connecting post is provided at the end of the inner shell facing away from the filter inlet, and a first drain channel is formed in the connecting post, the first drain channel connecting the second chamber to the manifold.

[0010] According to one embodiment of the present invention, the first drainage channel has a cross-sectional area smaller than that of the second chamber.

[0011] According to one embodiment of the present invention,

[0012] The outer periphery of the connecting column is provided with a sealing cover that extends radially outward. The outer periphery of the sealing cover abuts against the inner wall of the receiving cavity. The side of the sealing cover away from the inner shell and the inner sidewall of the receiving cavity define the confluence cavity.

[0013] According to one embodiment of the present invention, the manifold is optionally connected to the first chamber.

[0014] According to one embodiment of the present invention, the sealing cover is provided with a second drainage channel connecting the manifold and the first chamber, and a one-way valve is provided in the second drainage channel. The one-way valve is adapted to open the second drainage channel after the pressure in the first chamber reaches a preset pressure.

[0015] The garment processing device according to the present invention is briefly described below.

[0016] The garment processing device according to the present invention is provided with a filter assembly as described in any of the above embodiments, and a water inlet pipe, wherein a water inlet channel is formed within the water inlet pipe, and the water inlet channel connects the washing chamber of the garment processing device to the filter inlet. Because the garment processing device according to the present invention is provided with a filter assembly as described in any of the above embodiments, the garment processing device has a good filtration effect on the washing water, the water path is not easily clogged, and the garment processing device has a strong cleaning ability for clothes.

[0017] According to one embodiment of the present invention, the water inlet channel includes an extension section and a first narrowing section, wherein the cross-sectional area of ​​the first narrowing section is smaller than the cross-sectional area of ​​the extension section.

[0018] According to one embodiment of the present invention, the cross-sectional area of ​​the first reduced diameter section is S1, the cross-sectional area of ​​the extended section is S2, and S1 / S2 satisfies: 0.2≤S1 / S2<1.

[0019] According to one embodiment of the present invention, the garment processing device further includes: a water outlet pipe, wherein a water outlet channel is provided in the water outlet pipe, one end of the water outlet channel is connected to the second chamber, and the other end of the water outlet channel is connected to the washing chamber.

[0020] According to one embodiment of the present invention, the water outlet pipeline includes: a first section of the water outlet channel and a second reduced diameter section, wherein the cross-sectional area of ​​the first section of the water outlet channel is S3 and the cross-sectional area of ​​the second reduced diameter section is S4, and S3 and S4 satisfy: S3 > S4.

[0021] In summary, this application addresses the technical problems of existing filter components, especially those contaminated with lint and impurities, which reduce the flow rate of filtered water and result in low filtration efficiency and capacity. By employing a closed outer and inner shell, with the inner shell dividing the space within the outer shell into a first and second chamber, and connecting the filter component inlet to the first chamber and the filter component outlet to the second chamber, the filtered washing water flows from the first chamber into the second chamber. When the water flow is slowed down by the lint and impurities in the filter element, the water flowing into the outer chamber continuously increases the water pressure within the outer chamber, thereby increasing the flow rate of washing water through the filter component and improving filtration efficiency and capacity. Simultaneously, this application incorporates two reduced-diameter sections in the inlet and outlet pipes to enhance the water pressure of the washing water in the circulating filtration path. The combined effect of the filter component's cavity structure and the reduced-diameter section structure ensures that the filtered washing water has sufficient pressure to return to the washing chamber in a jet form, improving the washing effect and cleaning the drum of the garment processing equipment.

[0059] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0060] The following is for reference. Figures 1-15 A filter component 1 according to an embodiment of the present invention is described.

[0061] like Figures 2-4 and Figure 12 As shown, the filter assembly 1 according to the present invention includes a housing 11, a filter element 12, and a water inlet pipe 13. A first chamber 101 and a second chamber 102 are formed inside the housing 11. The first chamber 101 and the second chamber 102 can be used to contain unfiltered washing water and filtered washing water, respectively. The filter element 12 is disposed inside the housing 11 and separates the first chamber 101 and the second chamber 102. The filter element 12 can be a filter screen or other structure used to filter impurities in the water. The filter element 12 separates the first chamber 101 and the second chamber 102. After the washing water is filtered by the filter element 12, the impurities in the washing water can be filtered out, so that the impurities are retained on the filter element 12.

[0062] A water inlet channel is formed in the water inlet pipe 13. The water inlet channel can guide the washing water in the washing chamber of the clothes processing device 3 into the housing 11 of the filter assembly 1. One end of the water inlet channel can be connected to the water pump outlet of the clothes processing device 3, and the other end of the water inlet channel can be connected to the first chamber 101 to connect the washing chamber of the clothes processing device 3 with the first chamber 101.

[0063] like Figure 4 As shown, the washing water enters the first chamber 101 through the extension section 131. The portion located on the left side of the inner shell 112 and the portion around the inner shell 112 constitute the first chamber 101, wherein the liquid on the left side of the inner shell 112 can bypass the structure located at the left end of the inner shell 112.

[0064] After washing, the washing water enters the first chamber 101 through the water inlet channel and is filtered after flowing through the filter element 12.

[0065] like Figure 2 As shown, the water inlet channel includes an extension section 131 and a first narrowed section 132. The cross-sectional area of ​​the first narrowed section 132 is smaller than that of the extension section 131. The first narrowed section 132 can be located at either end of the extension section 131 or between the two ends of the extension section 131. In other words, the first narrowed section 132 can be located at any position within the water inlet channel.

[0066] In one specific embodiment of the present invention, the first reduced diameter section 132 is located at the end of the water inlet channel connected to the water pump outlet.

[0067] The cross-sectional area of ​​the first narrowing section 132 is reduced. With the flow rate at the inlet end remaining unchanged, the water flow velocity increases and the water pressure rises after passing through the first narrowing section 132, thereby increasing the water pressure in the first chamber 101. After the water pressure in the first chamber 101 increases, the flow velocity of the water through the filter element 12 is increased, thereby improving the filtration efficiency of the filter assembly 1.

[0068] The washing water needs to be filtered in the filter assembly 1 of the clothing processing equipment 3. The presence of the filter element 12 affects the flow rate of the water. When the water flows through the filter element 12, the flow rate is slow and the filtration efficiency is low.

[0069] In related technologies, the filter assembly of a washing machine is provided with a filter chamber. However, the cross-sectional area of ​​the flow area in the channel communicating with the filter chamber does not change, and no consideration is given to how to utilize the change in the cross-sectional area of ​​the flow area to improve the filtration effect of the filter chamber. Furthermore, some solutions simply place the filter assembly in the detergent dispenser to filter impurities in the water containing dissolved detergent. In such solutions, impurities may clog the filter holes of the filter assembly, resulting in a small flow rate of filtered water that cannot be used for spraying or rinsing clothes and the washing tub. According to the filter assembly 1 for the clothing processing device 3 of the present invention, by providing a water inlet channel, a first narrowing section 132 and an extension section 131 are provided in the water inlet channel. The cross-sectional area of ​​the first narrowing section 132 is smaller than that of the extension section 131, so that the pressure of the washing water increases and the flow rate increases after passing through the first narrowing section 132, thereby improving the filtration effect of the filter assembly 1 on the water flow.

[0070] like Figure 4 As shown, according to an embodiment of the present invention, at least a portion of the first chamber 101 is disposed on the outer periphery of the second chamber 102. Disposing the first chamber 101 on the outer periphery of the second chamber 102 facilitates the arrangement of the water inlet channel and increases the water inlet area of ​​the first chamber 101, thereby increasing the water inlet volume of the filter assembly 1. The second chamber 102 is disposed within the first chamber 101, allowing for better backflow of the filtered washing water. During the filtration process, the washing water flows from the peripheral outer chamber 101 towards the inner second chamber 102. The inlet water pressure in the first chamber 101 is high, and the water flow velocity at the outlet connected to the second chamber 102 is fast with low resistance. This arrangement improves the filtration efficiency of the filter assembly 1.

[0071] According to one embodiment of the present invention, the cross-sectional area of ​​the first narrowed section 132 is S1, and the cross-sectional area of ​​the extended section 131 is S2, wherein S1 / S2 satisfies 0.2≤S1 / S2<1. By setting the ratio of the cross-sectional areas of the first narrowed section 132 to the extended section 131 within the above range, the water flow velocity and water pressure in the downstream section of the first narrowed section 132 in the water inlet channel can be effectively increased, thereby improving the filtration efficiency of the filter assembly 1.

[0072] According to one embodiment of the present invention, the ratio of the cross-sectional area of ​​the first reduced diameter section 132 to the cross-sectional area of ​​the extended section 131 is set to S1 / S2 = 0.5.

[0073] like Figure 4 As shown, according to an embodiment of the present invention, a water outlet pipe is formed on the housing 11, and a water outlet channel 14 is provided in the water outlet pipe. The water outlet channel 14 can lead the filtered washing water out of the housing 11. One end of the water outlet channel 14 is connected to the second chamber 102, and the other end of the water outlet channel 14 is connected to the inner tub of the clothing processing device 3, so that the filtered water returns to the inner tub of the clothing processing device 3 and further washes the clothes.

[0074] The water outlet channel 14 includes a first section 141 and a second narrowed section 1421. The cross-sectional area of ​​the first section 141 is S3, and the cross-sectional area of ​​the second narrowed section 1421 is S4. S3 and S4 satisfy: S3 > S4. By setting the cross-sectional area of ​​the second narrowed section 1421 to be smaller than the cross-sectional area of ​​the first section 141, the water pressure after passing through the water outlet channel 14 can be increased.

[0075] Since the water outlet channel 14 needs to discharge the filtered water into the inner tub of the clothing processing equipment 3, the water pressure of the washing water after passing through the first diameter reduction section 132 and the second diameter reduction section 1421 is increased, so that the washing water can be guided into the washing tub in the form of spray to spray and clean the clothes and / or the inner wall of the washing tub.

[0076] For example, in this application, pressurized washing water is sprayed onto the garment processing equipment via a spraying method, which can more thoroughly soak the clothes and improve the cleaning effect of the garment processing equipment 3. It can also spray various parts of the inner tub as the inner tub rotates during the washing process to clean impurities or dirt remaining in the tub. In some embodiments, the sprayed water stream can also spray away foam generated during washing and / or rinsing to achieve a defoaming effect.

[0077] To meet the requirements of the spray range, it is necessary to ensure that the water flow has a certain pressure. By setting the first diameter reduction section 132, the closed outer cavity 101 and the second diameter reduction section 1421, the water pressure of the washing water is increased, which meets the spray requirements for washing and thus improves the cleaning effect of the clothing treatment equipment 3 on the clothes.

[0078] like Figure 4 As shown, according to an embodiment of the present invention, the housing 11 includes an outer shell 111 and an inner shell 112. A receiving cavity 1101 suitable for accommodating the inner shell 112 is formed in the outer shell 111. The receiving cavity 1101 is a naturally formed cavity in the outer shell 111 and is not the aforementioned first cavity 101. The receiving cavity 1101 can be divided. A part of the receiving cavity 1101 can be the aforementioned first cavity 101. One end of the outer shell 111 is provided with a filter assembly inlet 1003 that communicates with the other end of the water inlet pipe 13. The filter assembly inlet 1003 is connected to the receiving cavity 1101. The position of the filter assembly inlet 1003 in the receiving cavity 1101 is located on the inner sidewall of the first cavity 101.

[0079] The inner shell 112 is disposed within the receiving cavity 1101. The outer side wall of the inner shell 112 is spaced apart from the inner side wall of the outer shell 111 to form a first chamber 101. The inner shell 112 is housed within the receiving cavity 1101 formed by the outer shell 111. After the water flows into the filter assembly 1, it first disperses towards the first chamber 101 located on the outer periphery of the inner shell 112 to reduce the pressure entering the first chamber 101. A second chamber 102 is formed inside the inner shell 112. A connecting hole 1121 is provided on the outer periphery of the inner shell 112. A filter element 12 is provided on the connecting hole 1121. The connecting hole 1121 provided on the outer periphery of the inner shell 112 can increase the communication area between the first chamber 101 and the second chamber 102. The filter element 12 is provided on the connecting hole 1121 to filter the water flowing through the connecting hole 1121.

[0080] like Figure 4 As shown, the inner shell 112 has a connecting column 1122 at the end facing away from the filter assembly inlet 1003. A first drain channel 1123 is provided within the connecting column 1122, connecting the second chamber 102 to the manifold 103. The diameter of the first drain channel 1123 is smaller than the diameter of the second chamber 102, resulting in a smaller cross-sectional area. This increases the pressure of the washing water flowing from the second chamber 102 through the first drain channel 1123, thereby increasing the flow rate of the filtered washing water. The filtered washing water then has greater pressure when sprayed into the garment processing equipment 3, further expanding the spray range.

[0081] like Figure 4 and Figure 13As shown, according to one embodiment of the present invention, a sealing cover 1124 extending radially outward is provided on the outer periphery of the connecting post 1122. The outer periphery of the sealing cover 1124 abuts against the inner wall of the receiving cavity 1101. The side of the sealing cover 1124 away from the inner shell 112 defines the aforementioned confluence cavity 103 with the inner wall of the receiving cavity 1101. The side of the sealing cover 1124 facing the inner shell 112 defines a first chamber 101 between the inner sidewall of the receiving cavity 1101 and the outer sidewall of the inner shell 112. The sealing cover 1124 divides the space in the receiving cavity 1101 located on the outer periphery of the inner shell 112 into the confluence cavity 103 and the first chamber 101.

[0082] According to one embodiment of the present invention, a second drain channel 1125 is provided on the sealing cover 1124, connecting the manifold 103 and the first chamber 101. A one-way valve is provided in the second drain channel 1125. The one-way valve is adapted to open when the pressure in the first chamber 101 reaches a preset pressure, thereby opening the second drain channel 1125 and directly connecting the manifold 103 and the first chamber 101. When the pressure in the first chamber 101 is too high, the one-way valve opens, allowing the washing water in the first chamber 101 to flow to the manifold 103, thereby reducing the pressure in the first chamber 101 and ensuring the safety of the filter assembly 1.

[0083] According to one embodiment of the present invention, the filter assembly 1 further includes a sensor adapted to detect the opening and closing of the one-way valve. The sensor may be configured as a reed switch structure. The sensor can detect the opening of the one-way valve. After the one-way valve is opened, the sensor can transmit the opening signal of the one-way valve to the control center of the garment processing device 3. The control center controls the flow rate of the water pump. In some specific embodiments, after the one-way valve is opened, the water pump is controlled to reduce its power to reduce the flow rate of the water and relieve the pressure of the washing water in the first chamber 101.

[0084] like Figure 7 and Figure 12 As shown, according to another embodiment of the present invention, the filter assembly 1 includes a housing 11, a filter element 12, and a scraper 15. A first chamber 101 and a second chamber 102 are formed in the housing 11. Washing water from inside the garment processing device 3 can first enter the first chamber 101. The filter element 12 is disposed in the housing 11 and separates the first chamber 101 and the second chamber 102. The washing water entering the first chamber 101 can pass through the filter element 12 and then enter the second chamber 102. The filter element 12 is used to filter out impurities in the washing water, and the impurities will remain on the filter element 12.

[0085] In this application, the scraper 15 is disposed in the first chamber 101 or the second chamber 102, or in both the first chamber 101 and the second chamber 102. At least a portion of the scraper 15 abuts against the surface of the filter element 12 and is movable relative to the filter element 12. During the movement of the scraper 15, the portion of the scraper 15 that abuts against the surface of the filter element 12 can scrape off impurities from the surface of the filter element 12, thereby cleaning the filter element 12.

[0086] It should be noted that as the washing water in the first chamber 101 flows into the second chamber 102 of the filter element 12, and some of the washing water flows back to the first chamber 101 under the action of gravity, impurities will also remain on the side of the filter element 12 facing the second chamber 102. The impurities located in the second chamber 102 can be impurities formed by the filtration deposition of the filter element 12. The scraper 15 is set in the second chamber 102 and moves relative to the filter element 12 to scrape off the impurities on the side of the filter element 12 facing the second chamber 102, thereby ensuring the filtration effect of the filter element 12.

[0087] In some embodiments of the present invention, the scraper 15 may also be disposed on both sides of the filter element 12, and the scraper 15 may be moved relative to the filter element 12 to scrape off the impurities remaining on both sides of the filter element 12.

[0088] In related technologies, garment processing equipment is equipped with filter components. However, after working for a long time, a large amount of impurities will remain on the surface of the filter components. It is necessary to remove the filter components and clean the impurities on the surface of the filter components. The cleaning process can only rely on the user to manually remove the impurities, lint and other debris remaining on the filter screen. The operation is complicated and cumbersome, and the cleaning efficiency is low.

[0089] According to the filter assembly 1 of the present invention, a scraper 15 is provided in the filter assembly 1. The scraper 15 is movable relative to the filter element 12 to scrape off the impurities accumulated on the surface of the filter element 12. The scraper 15 improves the convenience for the user to remove impurities from the surface of the filter element 12.

[0090] The user can manually control the scraper 15, and by manually moving the scraper 15, the user can selectively scrape off the amount of impurities on the surface of the filter element 12 according to their own needs. According to one embodiment of the present invention, the housing 11 includes an outer shell 111 and an inner shell 112. A receiving cavity 1101 is formed in the outer shell 111, and a first chamber 101 is formed in the inner shell 112. The inner shell 112 is disposed in the receiving cavity 1101 and spaced apart from the inner sidewall of the outer shell 111 to form a second chamber 102. A connecting hole 1121 is provided on the outer periphery of the inner shell 112, and the aforementioned filter element 12 is disposed on the connecting hole 1121.

[0091] In this application, the inner shell 112 is disposed inside the outer shell 111, so that the first chamber 101 surrounds the second chamber 102. The filter element 12 is located on the inner shell 112, so that the filter element 12 has a larger filtration area, thereby improving the filtration efficiency of the filter assembly 1. The first chamber 101 is disposed on the outer periphery of the second chamber 102. When arranging the first chamber 101, the first chamber 101 can have a larger filter assembly inlet 1003, which increases the water intake of the filter assembly 1. The second chamber 102 is disposed inside the first chamber 101, so that the filtered washing water can be better returned. During the filtration process, the washing water flows from the outer periphery of the first chamber 101 to the inner periphery of the second chamber 102. The water pressure at the inlet of the first chamber 101 is high, and the washing water flow rate at the outlet is fast with low resistance. This arrangement can improve the filtration efficiency of the filter assembly 1.

[0092] like Figure 12 and Figure 13 As shown, according to one embodiment of the present invention, the outer shell 111 is provided with the scraping member 15, and the inner shell 112 is rotatable relative to the outer shell 111. During the rotation of the inner shell 112 relative to the outer shell 111, the scraping member 15 moves relative to the filter element 12, thereby scraping away impurities from the surface of the filter element 12. In this embodiment, by providing that the inner shell 112 can rotate relative to the outer shell 111, the surface of the filter assembly 1 can be cleaned without disassembling it.

[0093] For example, when the filter assembly 1 is not disassembled, the user can rotate the inner shell 112 so that the outer surface of the inner shell 112 rotates relative to the outer shell 111. The filter element 12 provided on the outer shell 111 remains on the inner surface of the outer shell 111. During the rotation of the inner shell 112 relative to the outer shell 111, impurities on the surface of the filter element 12 will be concentrated on one side of the filter element 12, thereby avoiding the impact of impurities on the filtration performance of the filter element 12.

[0094] When there are few impurities on filter assembly 1, rotating the inner shell 112 relative to the outer shell 111 removes impurities from its surface, improving the filtration capacity of the filter element 12. This allows impurities to be scraped off the surface of the filter element 12 without the user disassembling the filter assembly 1, preventing clogging and increasing the flow rate of water passing through it. Disassembling the filter assembly 1 after a period of use completely removes impurities, extending the maintenance cycle of the filter assembly 1.

[0095] like Figure 12As shown, according to an embodiment of the present invention, the scraper 15 includes a base plate 151 and scraper blades 152. The base plate 151 is disposed on the inner sidewall of the housing 111 and extends in the length direction of the housing 111. The scraper blades 152 are configured as a plurality and arranged at intervals on the base plate 151. The plurality of scraper blades 152 can be arranged at intervals in an axial direction perpendicular to the inner housing 112.

[0096] The inner shell 112 can be constructed as a cylinder, rotating around its axis. The outer shell 111 can also be constructed as a cylinder. A base plate 151 extends from one end of the outer shell 111 towards the other, with its extension direction parallel to the axis of the outer shell 111. Multiple scrapers 152 are spaced apart along the extension direction of the base plate 151, ensuring even distribution for scraping impurities from the filter element 12. During the scraping process, the filter element 12 does not generate excessive resistance to the rotation of the inner shell 112, facilitating its rotation.

[0097] According to one embodiment of the present invention, the scraping members 15 are configured as a plurality and are arranged at intervals in the circumferential direction on the inner sidewall of the housing 111. Arranging the scraping members 15 at intervals in the circumferential direction on the housing 111 can further improve the cleaning efficiency of the scraping members 15 on the filter element 12. During the process of rotating the inner housing 112 one revolution, each scraping member 15 moves relative to the filter screen.

[0098] In one embodiment of the present invention, two adjacent scraping members 15 are configured as a first scraping member and a second scraping member. The first scraping member is provided with a plurality of first scraping blades arranged at intervals in the length direction of the outer shell 111, and the second scraping member is provided with a plurality of second scraping blades arranged at intervals in the length direction of the outer shell 11. A notch is formed between any two first scraping blades, and the second scraping blades and the notch are directly opposite each other in the rotation direction of the inner shell 112.

[0099] When the first scraper scrapes the surface of the filter element 12, the gaps formed between two first scrapers cannot scrape the surface of the filter element 12 because the first scrapers are spaced apart. The second scraper adjacent to the first scraper is provided with several second scrapers. Each second scraper and the opposite gap are directly opposite each other in the rotation direction of the inner shell 112. After the filter element 12 is scraped by the first scraper, the part of the filter element 12 that is directly opposite the gap can be further scraped by the second scrapers in the second scraper, thereby making up for the drawback that the gap cannot clean the corresponding area on the filter element 12.

[0100] Furthermore, the second scraper and the notch are positioned circumferentially opposite each other, so that the circumferential flow of washing water into the first chamber 101 is unobstructed. Any two adjacent scrapers 15 can divide the first chamber 101 into multiple sub-chambers, and the notch connects the sub-chambers to each other to ensure smooth flow of washing water in the first chamber 101.

[0101] By setting up a first scraper and a second scraper, the surface of the filter element 12 can be thoroughly cleaned using the first scraper and the second scraper to remove impurities from every part of the surface of the filter element 12.

[0102] According to one embodiment of the present invention, the number of scraping elements 15 is not limited to two; there may be three or four scraping elements 15, and the plurality of scraping elements 15 are arranged at intervals in the circumferential direction of the housing 111.

[0103] According to one embodiment of the present invention, the first scraper, the second scraper, and the notch are the same size in the length direction of the housing 111. Setting the first scraper, the second scraper, and the notch to be the same size allows the first scraper and the second scraper to cover the entire area of ​​the surface of the filter element 12 with a minimum volume, which helps to reduce the size of the filter assembly 1 and reduce the influence of the scraper 152 on the flow of washing water in the first chamber 101.

[0104] In other embodiments of the present invention, the dimension of the second scraper in the length direction of the housing 111 may be larger than the dimension of the notch in the length direction of the housing 111, so as to increase the scraping area of ​​the second scraper and avoid creating cleaning dead corners on the filter element 12.

[0105] like Figure 13 As shown, according to an embodiment of the present invention, the inner shell 112 is detachably disposed within the outer shell 111. The inner shell 112 is provided with a cleaning member 16 that cooperates with the inner sidewall at one end opposite to the removal direction. The cleaning member 16 is adapted to move with the inner shell 112 when the inner shell 112 is removed from the outer shell 111, so that the cleaning member 16 collects and removes the impurities remaining on the inner surface of the outer shell 111 during the process of moving relative to the inner surface of the outer shell 111. The impurities are cleaned as the inner shell 112 is disassembled, which can further improve the cleaning effect of the filter assembly 1 on the inside of the receiving cavity 1101, and at the same time make the cleaning of the filter assembly 1 more convenient.

[0106] According to one embodiment of the present invention, the cleaning element 16 can be constructed as a flexible element, for example, the cleaning element 16 can be constructed as a cleaning foam, and the inner shell 112 can further clean the inner surface of the outer shell 111 by reciprocating movement.

[0107] like Figure 13As shown, according to an embodiment of the present invention, the cleaning component 16 can be constructed as a rigid component. The cleaning component 16 includes an extension 161 and a scraping ring 162. The extension 161 is disposed at one end of the inner shell 112 and extends towards the filter assembly inlet 1003 of the outer shell 111 at one end of the inner shell 112. The free end of the extension 161 is a closed structure to prevent the washing water entering the second chamber 102 from directly entering the second chamber 102 through the extension 161. The scraping ring 162 is disposed on the outer periphery of the extension 161. The outer periphery of the scraping ring 162 cooperates with the inner sidewall of the outer shell 111. The outer edge of the scraping ring 162 can abut against the inner sidewall of the outer shell 111. When the inner shell 112 is pulled away from the outer shell 111, the inner shell 112 drives the scraping ring 162 to move, so that the end face of the scraping ring 162 in the pulling direction scrapes the inner surface of the outer shell 111 to clean the inner surface of the outer shell 111.

[0108] According to one embodiment of the present invention, the scraping ring 162 can also be used to position the inner shell 112. The outer side wall of the scraping ring 162 abuts against the inner side wall of the outer shell 111, so that the inner shell 112 maintains a stable relative position with the outer shell 111. The inner shell 112, the outer shell 111 and the scraping ring 162 are arranged around the same axis.

[0109] like Figure 6 and Figure 7 As shown, according to an embodiment of the present invention, a movable groove 1126 is provided on the inner shell 112, and the scraper 15 includes a guide portion 153 and a scraper blade 152. The guide portion 153 cooperates with the movable groove 1126 and is adapted to move in the extension direction of the movable groove 1126. The movable groove 1126 is used to limit the movement direction of the guide portion 153. The movable groove 1126 can extend from one end of the inner shell 112 to the other end. The movable groove 1126 can be arranged parallel to the axis of the inner shell 112. Of course, the movable groove 1126 can be set to have a certain inclination angle with the axis of the inner shell 112.

[0110] The scraper 152 can move with the movement of the guide 153, and at least a portion of the outer periphery of the scraper 152 engages with the inner peripheral wall of the inner shell 112 to scrape off impurities on the inner peripheral wall.

[0111] like Figure 7 As shown, in one embodiment of the present invention, the scraper 152 is constructed as an arc-shaped scraper 152, the outer periphery of which matches the inner surface of the inner shell 112, so that when the scraper 15 is moved, all positions on the inner surface of the inner shell 112 can be scraped clean without leaving any dead corners.

[0112] According to one embodiment of the present invention, the scraper 152 may be configured as two, each scraper 152 being configured as a fan-shaped scraper, and the two fan-shaped scrapers forming a ring to clean the circumferential parts of the inner surface of the inner shell 112.

[0113] According to one embodiment of the present invention, two scraper blades 152 can rotate relative to each other to selectively tension on the inner surface of the inner shell 112. Since each scraper blade 152 has a fan-shaped structure, when the inner shell 112 needs to be cleaned, the two scraper blades 152 rotate toward each other to tension on the inner surface of the inner shell 112, maintaining the abutment between the scraper blades 152 and the inner surface of the inner shell 112.

[0114] According to one embodiment of the present invention, the guide portion 153 is configured as two, each guide portion 153 being connected to a corresponding scraper 152. The two guide portions 153 are hinged to each other so that the two scrapers 152 are rotatable relative to each other. An elastic element is also provided between the two guide portions 153 to maintain the two scrapers 152 in a tendency to move toward each other. When the user needs to clean the inside of the inner shell 112, by pressing the two guide portions 153, the two guide portions 153 are brought closer to each other, so that the two scrapers 152 inside the inner shell 112 are moved away from each other and tensioned inside the inner shell 112.

[0115] like Figures 9-13 As shown, according to an embodiment of the present invention, the filter assembly 1 includes a housing 111, an inner housing 112, and a filter element 12. A receiving cavity 1101 is formed inside the housing 111, and a first chamber 101 is formed inside the inner housing 112. The inner housing 112 is disposed inside the receiving cavity 1101 and spaced apart from the inner sidewall of the housing 111 to form a second chamber 102. A connecting hole 1121 is provided on the outer periphery of the inner housing 112 to connect the first chamber 101 and the second chamber 102. The filter element 12 covers the connecting hole 1121 to filter impurities passing through the connecting hole 1121.

[0116] The filter assembly 1 also includes a scraper 15, a first end cap 17, and a second end cap 18. The scraper 15 is disposed in the receiving cavity 1101 to scrape off impurities on the outer surface of the inner shell 112 during the rotation of the inner shell 112 relative to the outer shell 111. The first end cap 17 is disposed at one end of the outer shell 111 and is adapted to close the receiving cavity 1101. The second end cap 18 is connected to the inner shell 112 and can rotate relative to the first end cap 17. During the rotation, the second end cap 18 drives the inner shell 112 to rotate relative to the outer shell 111 so that the scraper 15 scrapes off impurities on the surface of the filter element 12 located on the inner shell 112.

[0117] According to the filter assembly 1 of the present invention, by providing a first end cap 17 to close one end of the outer shell 111, and a second end cap 18 that can rotate relative to the first end cap 17, the user can rotate the second end cap 18 without disassembling the filter assembly 1 to drive the inner shell 112 to rotate, so that the filter element 12 on the outer surface of the inner shell 112 moves relative to the scraper 15, thereby scraping off the impurities on the surface of the filter element 12.

[0118] Clothing processing equipment is equipped with a filter assembly. However, after prolonged use, a large amount of impurities accumulate on the filter surface, requiring removal and cleaning. This cleaning process relies solely on manual removal of residual impurities and lint from the filter screen, which is complex, cumbersome, and inefficient. The filter assembly 1 of this application, by providing a first end cap 17 and a second end cap 18 rotatable relative to the first end cap 17, connects the second end cap 18 to the inner shell 112. This allows for cleaning of the filter element 12 within the filter assembly 1 without disassembling the filter assembly 1, simply by rotating the second end cap 18. This improves the convenience and reduces the difficulty of cleaning the filter element 12, enhancing the user experience.

[0119] like Figure 9 As shown, according to an embodiment of the present invention, a first locking part 171 is provided on the first end cap 17, and a second locking part 181 is provided on the second end cap 18. The first locking part 171 and the second locking part 181 can be selectively locked. The filter assembly 1 can be installed on the housing of the garment processing device 3 or placed separately in the dispensing box. The first end cap 17 can be fixedly connected to the housing 111 of the garment processing device 3 or the dispensing box, and the first end cap 17 is detachably provided on the housing 111 of the garment processing device 3 or the dispensing box. The second end cap 18 protrudes from the housing of the garment processing device 3 or the housing of the dispensing box. The second end cap 18 is constructed as the external surface of the filter assembly 1. When operating the filter assembly 1, the user needs to transmit torque to the first end cap 17 through the second end cap 18.

[0120] A first locking part 171 and a second locking part 181 are respectively provided on the first end cap 17 and the second end cap, and the first locking part 171 and the second locking part 181 can be selectively locked. When the user needs to clean the surface of the filter element 12, the first end cap 17 and the second end cap 18 are not locked. When the user rotates the second end cap 18, the inner shell 112 rotates relative to the outer shell 111, so that the scraper 15 provided on the outer shell 111 can scrape off the impurities on the surface of the filter element 12. When the user needs to disassemble the filter assembly 1, the first locking part 171 and the second locking part 181 are locked so that the first end cap 17 and the second end cap 18 cannot rotate relative to each other. By driving the second end cap 18, the first end cap 17 is disengaged from the housing of the clothing processing device 3 or from the dispensing box, so as to complete the disassembly of the filter assembly 1.

[0121] By providing a first locking part 171 on the first end cover 17 and a second locking part 181 on the second end cover 18, the first locking part 171 and the second locking part 181 can achieve mutual locking between the first end cover 17 and the second end cover 18. This allows the second end cover 18 to drive the inner shell 112 to rotate, and also allows the first end cover 17 to disengage from the clothing processing device 3 housing 11 and the dispensing box when the second end cover 18 is driven, making the use of the filter assembly 1 more convenient.

[0122] like Figures 9-10 As shown, according to one embodiment of the present invention, the first locking portion 171 is configured as a first locking tooth, which is disposed on the side of the first end cover 17 facing the second end cover 18, and the second locking portion 181 is configured as a second locking tooth, which is disposed on the side of the second end cover 18 facing the first end cover 17. The first end cover 17 and the second end cover 18 can be selectively moved toward or away from each other to engage or disengage the first locking tooth and the second locking tooth.

[0123] There can be multiple first locking teeth, which are spaced apart circumferentially on the first end cover 17. Similarly, there can also be multiple second locking teeth, which are spaced apart circumferentially on the second end cover 18. When the first end cover 17 moves toward the first end cover 17, each first locking tooth can engage with two adjacent second locking teeth to achieve meshing between the multiple first locking teeth and the multiple second locking teeth. During the rotation of the second end cover 18 relative to the first end cover 17, the first locking teeth and the second locking teeth abut against each other to transmit torque, so that the first end cover 17 and the second end cover 18 move synchronously. When the second end cover 18 moves away from the first end cover 17, the second locking teeth disengage from the first locking teeth, and the first end cover 17 and the second end cover 18 can rotate relative to each other. The rotation of the second end cover 18 drives the inner shell 112 to rotate, so that the scraper 15 scrapes away impurities from the outer surface of the inner shell 112.

[0124] According to one embodiment of the present invention, a connecting post 1122 is provided at one end of the inner shell 112. The connecting post 1122 passes through the first end cover 17 and connects to the second end cover 18. A through hole suitable for the connecting post 1122 to pass through is provided on the first end cover 17. After the connecting post 1122 passes through the first end cover 17, it cooperates with the second end cover 18 to connect the second end cover 18 to the inner shell 112, so that the second end cover 18 and the inner shell 112 can rotate synchronously.

[0125] A first snap-fit ​​member 1122a is provided at the free end of the connecting post 1122, and a second snap-fit ​​member 182 is provided on the second end cover 18. The first snap-fit ​​member 1122a and the second snap-fit ​​member 182 are snap-fitted together, and the second end cover 18 is connected to the connecting post 1122 by snap-fitting. On the one hand, it facilitates the cooperation between the second end cover 18 and the connecting post 1122. On the other hand, after the second end cover 18 is snapped with the connecting post 1122, the second end cover 18 can move relative to the free end of the snap-fit ​​post in the cooperation direction of the first snap-fit ​​member 1122a and the second snap-fit ​​member 182, so that the second locking part 181 on the second end cover 18 can selectively engage with the first locking part 171 on the first end cover 17.

[0126] like Figures 9-10 As shown, according to an embodiment of the present invention, the first snap-fit ​​member 1122a is configured as a snap-fit ​​groove disposed on the outer periphery of the free end of the connecting post 1122. The snap-fit ​​groove has a first sidewall 1122a1 and a second sidewall 1122a2 spaced apart in the extending direction of the connecting post 1122. The second snap-fit ​​member 182 is configured as a claw disposed on the second end cap 18. At least a portion of the claw is disposed in the snap-fit ​​groove and can be selectively moved between the first sidewall 1122a1 and the second sidewall 1122a2.

[0127] The spacing direction between the first sidewall 1122a1 and the second sidewall 1122a2 is the direction of relative movement between the first end cap 17 and the second end cap 18. The claws provided on the second end cap 18 are at least partially received in the engagement groove. The first sidewall 1122a1 in the engagement groove is the sidewall close to the first end cap 17, and the second sidewall 1122a2 in the engagement groove is the sidewall close to the second end cap 18. The cooperation between the claws and the engagement groove can realize the circumferential transmission between the second end cap 18 and the connecting post. The engagement groove is also provided with a third sidewall 1122a3 and a fourth sidewall 1122a4 that are spaced apart in the circumferential direction. When at least part of the claws are provided in the engagement groove, driving the second end cap 18 can cause the claws on the second end cap 18 to abut against the third sidewall 1122a3 or the fourth sidewall 1122a4, and transmit torque through the contact between the claws and the third sidewall 1122a3 or the fourth sidewall 1122a4.

[0128] When the user needs to lock the first end cap 17 and the second end cap 18 together, the second end cap 18 moves toward the first end cap 17 in the extending direction of the connecting post 1122, and the pawl approaches the first side wall 1122a1 so that the second locking tooth on the second end cap 18 engages with the first locking tooth; when the user needs to disengage and rotate relative to the first end cap 17 and the second end cap 18 together, the second end cap 18 moves away from the first end cap 17 in the extending direction of the connecting post 1122, and the pawl approaches the second side wall 1122a2 so that the second locking tooth on the second end cap 18 disengages from the first locking tooth.

[0129] According to one embodiment of the present invention, the locking grooves and locking claws are each constructed as a plurality of corresponding slots and claws, which are spaced apart in the circumferential direction of the connecting post 1122. This improves the reliability of the fit between the connecting post 1122 and the second end cap 18.

[0130] According to one embodiment of the present invention, the free end of the connecting post 1122 is provided with an expansion joint 1122a5, which is located between two adjacent snap-fit ​​grooves. The expansion joint 1122a5 provides space for the deformation of the free end of the connecting post 1122. When the claw on the second end cap 18 is engaged with the snap-fit ​​groove, at least a portion of the claw will cross the connecting post 1122 and compress the connecting post 1122. In order to make the engagement between the second end cap 18 and the connecting post 1122 easier, an expansion joint 1122a5 is provided between two adjacent snap-fit ​​grooves. Each expansion joint 1122a5 divides the connecting post 1122 into at least two parts, and each part is provided with a snap-fit ​​groove. During the installation of the second end cap 18, each part deforms toward the expansion joint 1122a5 so that the claw can be more easily engaged in the snap-fit ​​groove, reducing the difficulty of the engagement between the second end cap 18 and the connecting post.

[0131] According to one embodiment of the present invention, the snap-fit ​​grooves are configured as two and symmetrically arranged on the outer peripheral wall of the connecting post 1122. The expansion joint 1122a5 is arranged on the symmetrical center line of the two snap-fit ​​grooves and extends through the diameter of the connecting post 1122 to divide the connecting post 1122 into two parts. During the snap-fit ​​process, the two parts can deform toward each other to reduce the difficulty of fitting the second end cap 18 with the connecting post 1122.

[0132] like Figure 13 As shown, according to one embodiment of the present invention, the scraping member 15 includes a base plate 151 and scraper blades 152. The base plate 151 is disposed on the inner sidewall of the housing 111 and extends in the length direction of the housing 111. There are multiple scraper blades 152 and they are arranged at intervals in the length direction of the base plate 151. Each scraper blade 152 extends toward the filter element 12. A base plate mating groove 1102 suitable for receiving the base plate 151 is provided on the housing 111. At least a portion of the base plate 151 is received in the base plate mating groove 1102 so that the scraping member 15 is detachably disposed on the housing 111.

[0133] The outer casing 111 can be constructed as a cylindrical structure. A bottom plate mating groove 1102 that runs through the thickness direction is provided on the side wall of the outer casing 111. The extension direction of the bottom plate mating groove 1102 is parallel to the axial direction of the outer casing 111. The bottom plate mating groove 1102 and the scraper 15 are constructed as two corresponding bottom plate mating grooves 1102, which are directly opposite each other.

[0134] likeFigure 1 , Figures 14-15 As shown, the dispensing box 2 according to an embodiment of the present invention will be briefly described below.

[0135] The dispensing box 2 according to the present invention includes a dispensing box body 21 and a filter assembly 1. A filter chamber 210 is formed within the dispensing box body 21. The filter chamber 210 is provided with a first mating part 2101 connected to an inlet pipe 13 and a second mating part 2102 connected to an outlet pipe. The filter assembly 1 is disposed within the filter chamber 210 and has a third mating part 1001 and a fourth mating part 1002. A filter assembly inlet 1003 is provided on the third mating part 1001. The third mating part 1001 engages with the first mating part 2101 to filter... The component inlet 1003 is connected to the water inlet pipe 13. The fourth mating part 1002 is provided with a filter component outlet 1004. The fourth mating part 1002 and the second mating part 2102 are mated to connect the filter component outlet 1004 to the water outlet pipe. The first mating part 2101 and the third mating part 1001 are snap-fitted together, or the second mating part 2102 and the fourth mating part 1002 are snap-fitted together. Alternatively, the first mating part 2101 and the third mating part 1001, and the second mating part 2102 and the fourth mating part 1002 can be snap-fitted together simultaneously.

[0136] Water can easily leak between the filter and the dispensing box. When the leaked water remains in the filter chamber, it can easily breed bacteria and produce odors.

[0137] In related technologies, the filter installed in the dosing box assembly is generally a mesh filter to filter the washing water flowing through it. This filtration effect is not good, the filter is easy to clog, and there is no fit between the filter and the filter chamber, so there is a risk that the filtered water may remain in the filter chamber.

[0138] According to the dispensing box 2 of the present invention, water flow will not enter the filter chamber 210. The water flow needs to enter the interior of the filter assembly 1 for filtration and does not pass through the filter chamber 210. The filter assembly 1 and the dispensing box body 21 are connected by the first mating part 2101 and the third mating part 1001, and the second mating part 2102 and the fourth mating part 1002. This improves the reliability of the fit between the filter assembly inlet 1003 and the water inlet pipe 13, and between the filter assembly outlet 1004 and the water outlet pipe. This effectively improves the sealing performance of the filter assembly 1 with the water inlet pipe 13 and the water outlet pipe, avoids water residue in the filter chamber 210, and reduces the environment for odor generation and bacterial growth in the dispensing box 2.

[0139] According to one embodiment of the present invention, a receiving cavity 1101 is provided inside the filter assembly 1, and the filter assembly inlet 1003 communicates with the receiving cavity 1101 and is located at the bottom of one end face of the filter assembly 1. During the filtration process, the first mating part 2101 is connected to the third mating part 1001 so that the filter assembly inlet 1003 communicates with the water inlet pipe 13, and the third mating part 1001 is connected to the fourth mating part 1002 so that the filter assembly outlet 1004 communicates with the water outlet pipe, thereby forming a water passage through the water inlet pipe 13, the receiving cavity 1101, and the water outlet pipe, and the water inlet pipe 13 is connected to a water pump. When filtration is stopped, the water pump stops working, and the water flow between the water inlet pipe 13, the receiving cavity 1101, and the water outlet pipe stops. The third mating part 1001 is located at the bottom of one end face of the filter assembly 1. Under the action of gravity, the washing water flows downward. The water flow in the cavity of the filter assembly 1 can flow back into the water inlet pipe 13 through the filter assembly inlet 1003 provided on the third mating part 1001, so as to avoid residual water remaining in the cavity 1101. This further avoids the presence of residual water in the cavity 1101 of the filter assembly 1, thereby further reducing the residual water in the filter assembly 1 and reducing the environment for odor generation and bacterial growth in the dispensing box 2.

[0140] According to one embodiment of the present invention, one of the first mating part 2101 and the third mating part 1001 is a limiting protrusion, and the other of the first mating part 2101 and the third mating part 1001 is a limiting groove 214 that mates with the limiting protrusion. When the filter assembly 1 is properly mated in the filter cavity 210, the limiting protrusion can be inserted into the limiting groove 214, and the peripheral wall of the limiting groove 214 restricts the movement of the limiting protrusion. In some embodiments, the filter assembly inlet 1003 is located at the free end of the limiting protrusion, and a channel is provided in the limiting protrusion to communicate with the receiving cavity 1101 inside the filter assembly 1. The inner wall of the limiting groove 214 wraps around the outer periphery of the limiting protrusion to seal the third mating part 1001 and the first mating part 2101, and at the same time, it can support and position one end of the filter assembly 1.

[0141] like Figure 14 As shown, according to an embodiment of the present invention, a support groove 215 is provided in the filter cavity 210 to abut against the outer peripheral wall of one end of the filter assembly 1. The limiting groove 214 is formed on the inner peripheral wall of the support groove 215. The support groove 215 is supported on the outer peripheral wall of one end of the filter assembly 1. The support groove 215 can be used to support the outer peripheral wall of one end of the filter assembly 1. The support groove 215 is constructed as a groove recessed in the filter cavity 210 in the extending direction of the filter assembly 1. After the filter assembly 1 is installed in place, at least a portion of the inner sidewall of the support groove 215 abuts against the outer peripheral wall of one end of the filter assembly 1 to support the filter assembly 1.

[0142] The third mating part 1001 is located on the lower side of one end face of the filter assembly 1. A limiting groove 214 is provided at the bottom of the inner wall of the support groove 215. The limiting groove 214 can be constructed as a groove structure that is recessed downward at the bottom of the inner wall of the support groove 215. When the filter assembly 1 is in place, the third mating part 1001 located at the bottom of one end of the filter assembly 1 can be embedded into the limiting groove 214 at the bottom of the support groove 215, thereby restricting the rotation of the filter assembly 1.

[0143] According to one embodiment of the present invention, the limiting groove 214 has a first segment 2141 and a second segment 2142 in the extending direction of the filter assembly 1. The first segment 2141 is constructed as an annular groove facing the peripheral wall of the limiting protrusion, and the second segment 2142 is constructed as an arcuate groove that at least partially mates with the limiting protrusion. The first segment 2141 and the second segment 2142 are connected sequentially in the extending direction of the filter assembly inlet 1003. The first segment 2141 is constructed as an annular groove, and the axis of the annular groove is the same as the extending direction of the filter assembly inlet 1003. The annular groove can cover and support the outer periphery of the third limiting part, thereby improving the sealing effect of the limiting groove 214 on the third mating part 1001. The second segment 2142 is constructed as an arcuate groove to facilitate the insertion of the third mating part 1001 into the limiting groove 214, thereby facilitating the installation of the filter assembly 1.

[0144] like Figure 15 As shown, according to one embodiment of the present invention, the fourth mating part 1002 is disposed at the bottom of the filter assembly 1 and extends in a direction away from the filter assembly 1. The fourth mating part 1002 can be constructed as a protruding structure disposed at the bottom of the filter assembly 1. A channel is formed inside the protruding structure. The channel connects the filter assembly outlet 1004 on the fourth mating part 1002 with the receiving cavity 1101. Disposing the fourth mating part 1002 on the bottom wall of the filter assembly 1 can also drain the residual water in the receiving cavity 1101 of the filter assembly 1.

[0145] A second mating part 2102 extending into the filter chamber 210 is provided on the bottom wall of the filter chamber 210. The second mating part 2102 engages with the fourth mating part 1002. A limiting notch 2102a is provided on the second mating part 2102. After the filter assembly 1 is installed in place, the fourth mating part 1002 engages in the limiting notch 2102a to connect the filter assembly outlet 1004 to the water outlet pipe. The limiting notch 2102a on the second mating part 2102 can be used to position the filter assembly 1 to ensure reliable connection between the filter assembly outlet 1004 and the water outlet channel 14.

[0146] According to one embodiment of the present invention, the dispensing box body 21 is provided with a filter loading port 212 communicating with the filter chamber 210. The filter loading port 212 is an open opening that communicates the filter chamber 210 with the external space, so that the filter assembly 1 can be detachably disposed in the filter chamber 210. A limiting notch 2102a is disposed on the side of the second mating part 2102 facing the filter loading port 212. When the filter assembly 1 is installed, the filter assembly 1 moves toward the filter loading port 212. After moving to a preset position, the fourth mating part 1002 located on the lower side of the filter assembly 1 cooperates with the limiting notch 2102a to limit the movement distance of the filter assembly 1 in the extension direction of the filter chamber 210.

[0147] According to one embodiment of the present invention, the fourth mating part 1002 is configured as a cylindrical limiting protrusion, and the limiting notch 2102a is configured as a semi-circular groove facing the filter loading port 212. The fourth mating part 1002 is embedded in the semi-circular groove, and the side wall of the fourth mating part 1002 away from the filter loading port 212 abuts against the inner side wall of the semi-circular groove to limit the filter assembly 1 from continuing to move in the direction away from the filter loading port 212.

[0148] According to one embodiment of the present invention, the filter assembly 1 is detachably disposed within the filter chamber 210 via the filter loading port 212, and the direction of detachment of the filter assembly 1 can be the extending direction of the filter chamber 210, i.e., the front-to-back direction of the loading box 2. This facilitates the user to remove and disassemble the filter assembly 1 from the front of the garment processing device 3.

[0149] According to one embodiment of the present invention, a guide groove 216 is provided on the bottom wall of the filter chamber 210. The extension direction of the guide groove 216 is the same as the extraction direction of the filter assembly 1. The guide groove 216 can further guide the installation of the filter assembly 1. After the filter assembly 1 is installed in place, the guide groove 216 can also support the side of the filter assembly 1 to achieve positioning of the filter assembly 1.

[0150] According to one embodiment of the present invention, a first guide rib 2161 and a second guide rib 2162 are provided on the bottom wall of the filter cavity 210. The first guide rib 2161 and the second guide rib 2162 are spaced apart to form a guide groove 216. During the installation of the filter assembly 1, the bottom of the filter assembly 1 is in contact with the surfaces of the first guide rib 2161 and the second guide rib 2162 that are directly opposite each other. The extending directions of the first guide rib 2161 and the second guide rib 2162 are consistent with the extending direction of the filter cavity 210, so as to ensure that the filter assembly 1 can be accurately fitted into place during the installation process and avoid misalignment of the filter assembly 1.

[0151] According to one embodiment of the present invention, the first guide rib 2161 and the second guide rib 2162 gradually increase in height in the extraction direction of the filter assembly 1. It can be understood that the upper surfaces of the first guide rib 2161 and the second guide rib 2162 are inclined, and the inclination direction can be that each guide rib is higher in the front and lower in the back, so that the filter assembly 1 is inclined. The filter assembly inlet 1003 of the inclined filter assembly 1 is at the lowest position of the entire filter assembly 1, so that the residual water in the filter assembly 1 will flow towards the filter assembly inlet 1003 under the action of gravity, so as to guide the water inlet pipe 13 and avoid the generation of residual sewage in the filter assembly 1.

[0152] like Figure 14 As shown, according to an embodiment of the present invention, a partition plate 217 is provided inside the dispensing box body 21 to divide the interior of the dispensing box body 21 into a filter chamber 210 and a detergent dispensing chamber 211. A through hole 2171 is provided on the partition plate 217, which can connect the detergent dispensing chamber 211 and the filter chamber 210. A drain outlet 213 is provided on the dispensing box body 21.

[0153] In this embodiment, the filter chamber 210 and the detergent dispensing chamber 211 are integrated on the same box body, which improves the integration of the dispensing box 2. The drain outlet 213 provided on the dispensing box body 21 can introduce detergent into the inner tub of the clothing processing device 3. This embodiment is an improvement on the solution with only the detergent dispensing chamber 211 by adding the filter chamber 210. By setting the partition plate 217 to form the detergent dispensing chamber 211 and the filter chamber 210, the problem of sharing the drain outlet 213 can be solved by setting the connecting hole 1121 on the partition plate 217, saving the cost of redevelopment.

[0154] In addition, the drain outlet 213 is located on the bottom wall of the filter chamber 210, which can also guide water to the inner tub of the clothing treatment device 3 when there is residual water in the filter chamber 210, so as to avoid water residue.

[0155] According to one embodiment of the present invention, the dispensing box 2 includes a dispensing box body 21 and a filter assembly 1. A filter chamber 210 is provided inside the dispensing box. The filter chamber 210 is provided with a first mating part 2101 connected to the water inlet pipe 13 and a second mating part 2102 connected to the water outlet pipe. The filter assembly 1 is disposed in the filter chamber 210 and has a third mating part 1001 and a fourth mating part 1002. The third mating part 1001 is provided with a filter assembly inlet 1003 connected to the water inlet pipe 13, and the fourth mating part 1002 is provided with a filter assembly outlet 1004 connected to the water outlet pipe.

[0156] At least one of the third mating part 1001 and the fourth mating part 1002 is disposed at the bottom of the filter assembly 1 so that the residual water in the filter assembly 1 can easily flow out. At the same time, the filter assembly 1 is tilted, and the tilting direction of the filter assembly 1 is towards the third mating part 1001 or the fourth mating part 1002 located at the bottom of the filter assembly 1, so as to further guide the residual water in the filter assembly 1 to a lower place, thereby sufficiently reducing the residual water in the filter assembly 1.

[0157] According to the dispensing box 2 of the present invention, by setting one of the third mating part 1001 and the fourth mating part 1002 at the bottom of the filter assembly 1 and setting the filter assembly 1 at an angle, water is less likely to remain inside the filter assembly 1 and water can be discharged from the outside of the filter assembly 1 more easily.

[0158] According to one embodiment of the present invention, the height of the fourth mating part 1002 is lower than the height of the third mating part 1001. The fourth mating part 1002 is provided with a filter assembly outlet 1004. When the fourth mating part 1002 is located at the lowest point of the filter assembly 1, the water in the filter assembly 1 can be fully discharged, so that the water in the filter assembly 1 flows to the downstream water outlet pipe, so as to avoid residue in the filter assembly 1.

[0159] like Figure 15 As shown, according to an embodiment of the present invention, the third mating part 1001 may be located at the bottom of one end face of the filter assembly 1. When there is water inside the filter assembly 1, the water may also flow back into the water inlet pipe 13 through the filter assembly inlet 1003.

[0160] like Figure 14 and Figure 15 As shown, according to one embodiment of the present invention, a first guide rib 2161 and a second guide rib 2162 extending between a first mating portion 2101 and a second mating portion 2102 are provided on the bottom wall of the filter chamber 210. The first guide rib 2161 and the second guide rib 2162 are spaced apart to form a guide groove 216 suitable for accommodating the filter assembly 1. The first guide rib 2161 and the second guide rib 2162 are inclined. When the filter assembly 1 is installed in the filter chamber 210, the filter assembly 1 is supported in the guide groove 216. The bottom wall of the filter assembly 1 abuts against the upper ends of the first guide rib 2161 and the second guide rib 2162, respectively. The first guide rib 2161 and the second guide rib 2162 are inclined to maintain the inclination of the filter assembly 1, thereby allowing the washing water inside the filter assembly 1 to be quickly discharged and avoiding residue.

[0161] According to one embodiment of the present invention, the inclination angle between the upper end faces of the first guide rib 2161 and the second guide rib 2162 is α, where α satisfies: 1°≤α≤15°

[0162] like Figure 14 As shown, according to one embodiment of the present invention, the upper end face of the first guide rib 2161 is constructed as a first inclined surface 2161a, and the upper end face of the second guide rib 2162 is constructed as a second inclined surface 2162a. The first inclined surface 2161a and the second inclined surface 2162a are inclined toward the bottom wall of the filter assembly 1 in a direction toward each other. In an embodiment of the present invention, the outer shell 111 of the filter assembly 1 can be constructed as a cylindrical structure. By providing the first inclined surface 2161a and the second inclined surface 2162a, better contact can be made with the filter assembly 1, and the filter assembly 1 can be more stably supported on the first guide rib 2161 and the second guide rib 2162.

[0163] According to one embodiment of the present invention, a drain outlet 213 communicating with the filter assembly 1 is formed in the filter chamber 210, and a communication notch 2163 is provided on at least one of the first guide rib 2161 and the second guide rib 2162. In some embodiments, a detergent dispensing chamber 211 is also provided in the dispensing box 2. The detergent dispensing chamber 211 is used to dispense detergent, and the detergent needs to enter the inner tub of the clothing processing device 3 through the drain outlet 213. The drain outlet 213 is located between the first guide rib 2161 and the second guide rib 2162. By providing a communication notch 2163 on the first guide rib 2161 or the second guide rib 2162, it is ensured that most of the detergent in the detergent dispensing chamber 211 enters the drain outlet 213, and the first guide rib 2161 or the second guide rib 2162 is prevented from affecting the flow of detergent.

[0164] The connecting gaps 2163 are configured in multiple ways and are arranged at intervals in the extending direction of the first guide rib 2161 or the second guide rib 2162. By arranging the connecting gaps 2163 at intervals on the first guide rib 2161 or the second guide rib 2162, the obstruction of the first guide rib 2161 or the second guide rib 2162 to the flow of detergent can be further reduced, and the amount of detergent residue in the washing chamber can be reduced.

[0167] When the filter assembly 1 is installed in the filter chamber 210, the first end cap 17 is threadedly engaged with the filter loading port 212 to achieve the installation of the filter assembly 1. The second end cap 18 can rotate relative to the first end cap 17 and drive the inner shell 112 to rotate, so that the impurities on the surface of the filter element 12 are scraped off under the action of the scraper 15. Therefore, the loading box 2 is easy to install and the filter element 12 is easy to clean.

[0168] According to one embodiment of the present invention, a drain outlet 213 is provided on the dispensing box body 21, and a detergent dispensing chamber 211 spaced apart from the filter chamber 210 is also formed inside the dispensing box body 21.
