Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0063] In the field of washing machine technology, clothes generate lint during the washing process. To prevent lint from clogging the washing machine's internal pipes, a filter screen is usually installed in the water circuit. The filter screen can effectively filter lint in the water circuit, but it is difficult to clean. If the lint in the filter screen accumulates to a certain extent and is not cleaned in time, it will affect the fluid flow in the pipes.

[0064] Based on this, the following embodiments are proposed.

[0065] Example 1:

[0066] like Figure 1 , 2 As shown, this embodiment provides a self-cleaning structure, including:

[0067] The housing 1 has a cleaning chamber 2, an inlet 3 communicating with the cleaning chamber 2, and a first outlet 4.

[0068] Filter screen 5 is located in the cleaning chamber 2 and between the water inlet 3 and the first water outlet 4, and is used to filter the water that enters the cleaning chamber 2 through the water inlet 3.

[0069] Cleaning component 67 is disposed in cleaning chamber 2 and is movable under the impact of fluid;

[0070] The cleaning component 67 can come into contact with the surface of the filter screen 5 during operation to clean the surface of the filter screen 5.

[0071] In this embodiment, the fluid enters the cleaning chamber 2 through the inlet 3. During the entry process, the fluid generates an impact force on the cleaning component 67. Under the action of the fluid impact force, the cleaning component 67 rotates or swings rapidly. While the cleaning component 67 rotates or swings rapidly, it continuously scrapes the side wall of the filter screen 5, which can remove the lint intercepted on the side wall of the filter screen 5 by scraping and brushing, thereby realizing the self-cleaning function.

[0072] More specifically, this self-cleaning structure can be used in a washing machine. Washing water enters the cleaning chamber 2 through the inlet 3. The washing water is filtered through the filter screen 5 to remove lint. This device can recycle the washing water, saving water resources. When the cleaning component 67 rotates under the force of the washing water, the cleaning component 67 rotates or swings rapidly while continuously scraping the side wall of the filter screen 5. The lint intercepted on the side wall of the filter screen 5 can be removed by scraping. When the washing machine drains, water can be passed through the filter screen 5 in a direction different from the direction of the filtered fluid, so that the scraped lint can be discharged through the washing water.

[0073] This self-cleaning structure is simple, requires no power supply, and is low in cost.

[0074] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown in 6 and 7,

[0075] The filter screen 5 is a cylindrical mesh structure set in the cleaning chamber 2. The filter screen 5 has an outer mesh surface on its outer periphery and an inner mesh surface on its inner periphery. The inner mesh surface is arranged to form a cavity that connects to the first water outlet 4.

[0076] The cleaning component 67 includes a rotating body 6 and a scraping condition 7. The rotating body 6 is rotatably connected to the cleaning chamber 2 and rotates under the action of fluid force. The scraping condition 7 is connected to the rotating body 6 and at least a portion of the scraping condition 7 is disposed in contact with the surface of the filter screen 5.

[0077] When the rotating body 6 is rotated by the impact of the fluid, it can drive the scraper 7 to rotate around the outer mesh surface of the filter screen 5 in order to clean the outer mesh surface of the filter screen 5.

[0078] In this embodiment, the fluid enters the cleaning chamber 2 through the inlet 3. During the entry process, the fluid generates an impact force on the rotating body 6. The rotating body 6 rotates rapidly under the action of the fluid impact force. The rotating body 6 drives the scraping condition 7 to rotate. The scraping condition 7 rotates rapidly and continuously scrapes the outer mesh surface of the filter screen 5. The lint intercepted on the side wall of the filter screen 5 can be removed by scraping and brushing, thereby realizing the self-cleaning function.

[0079] More specifically, this self-cleaning structure can be used in a washing machine. Washing water enters the cleaning chamber 2 through the inlet 3. The washing water is filtered through the filter screen 5 to remove lint. This device can recycle washing water and save water resources. When the rotating body 6 rotates under the force of the washing water, it will drive the scraper 7 to rotate. The filter screen 5 is in a fixed state, so the rotation of the scraper 7 will cause friction with the outer surface of the hollow cylindrical filter screen 5. The scraper 7 scrapes the lint on the side of the hollow cylindrical filter screen 5 and removes the lint attached to the side of the hollow cylindrical filter screen 5. When the washing machine drains, water can be passed through the filter screen 5 in a direction different from the direction of the filtered fluid to discharge the scraped lint through the washing water.

[0080] Optionally, in one implementation of this embodiment, such as Figure 1 , 6 As shown in Figure 7,

[0081] The scraping condition 7 includes a connecting part 701 and a scraping strip part 702 that are connected to each other. The connecting part 701 is connected to the rotating body 6 in a transmission manner, and the scraping strip part 702 is attached to the outer mesh surface of the filter screen 5.

[0082] In this embodiment, fluid enters the cleaning chamber 2 through the inlet 3. During the entry process, the fluid generates an impact force on the rotating body 6. The rotating body 6 rotates rapidly under the action of the fluid impact force. The rotating body 6 drives the connecting part 701 to rotate. The rotation of the connecting part 701 drives the scraper part 702 to rotate. The scraper part 702 rotates rapidly and continuously scrapes the outer mesh surface of the filter screen 5. The lint intercepted on the side wall of the filter screen 5 can be removed by scraping and brushing, thereby realizing the self-cleaning function.

[0083] Optionally, in one implementation of this embodiment, such as Figure 1 , 6 As shown in Figure 7,

[0084] The rotating body 6 and the scraping condition 7 have the same axis of rotation, and the axis of rotation of the rotating body 6 and the scraping condition 7 is collinear with the central axis of the filter screen 5 of the cylindrical mesh structure.

[0085] The central axes of the rotating body 6, the scraping condition 7, and the filter screen 5 are collinear. This design allows the rotating body 6 to directly drive the scraping condition 7 to rotate during rotation. The driving method is simple and effective, achieving efficient scraping of the filter screen 5.

[0086] Optionally, in one implementation of this embodiment, such as Figure 1 , 6 As shown in Figure 7,

[0087] The connecting part 701 includes a first connecting plate 7010 and a connecting post 7011. The first connecting plate 7010 has a first plate surface close to the rotating body 6 and a second plate surface away from the rotating body. One end of the connecting post 7011 is connected to the center of the first plate surface. The connecting post 7011 passes through the shaft hole of the rotating body 6.

[0088] The scraper section 702 includes a plurality of scrapers, one end of which is connected to the second plate surface of the first connecting plate 7010, and the other end extends toward the filter screen 5.

[0089] The scraper extending toward one side of the filter screen 5 is at least partially in contact with the outer mesh surface of the filter screen 5.

[0090] In this embodiment, the connecting column 7011 and the rotating body 6 are coaxially assembled and have a certain interference fit. The fluid enters the cleaning chamber 2 through the inlet 3. During the entry process, the fluid generates an impact force on the rotating body 6. The rotating body 6 rotates rapidly under the action of the fluid impact force. The rotating body 6 drives the first connecting plate 7010 to rotate. The scraper part 702 rotates with the first connecting plate 7010. The scraper part 702 rotates rapidly and continuously scrapes the side wall of the filter screen 5. It can remove the lint intercepted on the side wall of the filter screen 5 by scraping and brushing, thereby realizing the self-cleaning function.

[0091] Optionally, in one implementation of this embodiment, such as Figure 1 , 6 As shown in Figure 7,

[0092] The rotating body 6 includes an impeller rotatably disposed within the cleaning chamber 2, the impeller having multiple blades;

[0093] Wherein, in the extending direction of the water inlet 3, the blade corresponds at least partially to the water inlet 3.

[0094] At least a portion of the blade in the vertical direction corresponds to the inlet 3 in the horizontal direction.

[0095] In this embodiment, the fluid is designed to enter the cleaning chamber 2 through the inlet 3. During the entry process, the fluid directly impacts the impeller, causing it to rotate rapidly. The impeller drives the first connecting plate 7010 to rotate, and the scraper 702 rotates with the first connecting plate 7010. The scraper 702 rotates rapidly while continuously scraping the side wall of the filter screen 5, which can remove the lint intercepted on the side wall of the filter screen 5 by scraping, thereby achieving the self-cleaning function.

[0096] Optionally, in one implementation of this embodiment, such as Figure 1 , 6 As shown in Figure 7,

[0097] The self-cleaning structure also includes:

[0098] The filter frame 8 includes a base 801 and a connecting frame 802. One end of the base 801 is connected to the filter screen 5 and the connecting frame 802, and the other end of the base 801 is connected to the inner wall of the housing 1 near the first outlet 4.

[0099] The connecting frame 802 includes a connecting rod 8021 and a second connecting plate 8022. One end of the connecting rod 8021 is connected to the base 801, and the other end of the connecting rod 8021 is connected to the second connecting plate 8022. The second connecting plate 8022 is connected to the inner wall of the housing 1 near the water inlet 3. The end of the connecting column 7011 away from the first connecting plate is rotatably connected to the second connecting plate 8022.

[0100] The filter frame 8 provides fixed support for the filter screen 5, keeping the filter screen 5 in a fixed state within the cleaning chamber 2. Therefore, when the scraper bar 702 rotates, it will rub against the side of the hollow cylindrical filter screen 5. The scraper bar 702 scrapes the lint off the side of the hollow cylindrical filter screen 5, removing the lint adhering to the side of the hollow cylindrical filter screen 5. When the washing machine drains, water can be passed through the filter screen 5 in a direction different from the direction of the filtered fluid, so that the scraped lint can be discharged through the washing water.

[0101] The connecting rod 8021 fixes the second connecting plate 8022 to the upper side of the filter screen 5. The second connecting plate 8022 is connected to the inner wall of the housing 1 near the water inlet 3. The other end of the base 801 is connected to the inner wall of the housing 1 near the first water outlet 4, so that the filter screen frame 8 can be firmly fixed in the cleaning chamber 2. Thus, the filter screen frame 8 can firmly fix the filter screen 5 and the scraper 7. The scraper 7 can rotate more stably in the cleaning chamber 2 to clean the filter screen 5.

[0102] Optionally, in one implementation of this embodiment, such as Figure 2 As shown,

[0103] The housing 1 includes a first housing 101 and a housing cover 102 connected to each other. The first housing 101 has a first cleaning chamber 201 away from the housing cover 102 and a second cleaning chamber 202 close to the housing cover 102. A water inlet 3 is formed on the first housing 101 and a first water outlet 4 is formed on the housing cover 102.

[0104] The filter screen 5 and the connecting bracket 802 are both located in the first cleaning chamber 201, and the seat 801 is located in the second cleaning chamber 202.

[0105] In this embodiment, the first housing 101 and the housing cover 102 are detachably connected, which can be a threaded connection. The first housing 101 and the housing cover 102 form an easily detachable housing 1, making the self-cleaning structure easy to assemble. Fluid enters the cleaning chamber 2 through the inlet 3. During the entry process, the fluid generates an impact force on the impeller. The impeller rotates rapidly under the action of the fluid impact force. The impeller drives the connecting part 701 to rotate. The rotation of the connecting part 701 drives the scraper part 702 to rotate. The scraper part 702 rotates rapidly and continuously scrapes the side wall of the filter screen 5. It can remove the lint intercepted on the side wall of the filter screen 5 by scraping, thereby realizing the self-cleaning function. The filtered fluid continues to flow to the next stage along the first outlet 4.

[0106] Optionally, in one implementation of this embodiment, such as Figure 3 As shown,

[0107] The diameter of the inlet 3 gradually decreases from the side furthest from the cleaning chamber 2 to the side closest to the cleaning chamber 2.

[0108] In this embodiment, preferably, in the assembled state, the water inlet 3 is located on the upper side of the rotating body 6. When the self-cleaning structure is used in a washing machine, the washing water impacts the rotating body 6 under the action of gravity, which can further increase the rotation speed of the rotating body 6 and improve the cleaning efficiency of the scraper 702 on the side wall of the filter screen 5.

[0109] The design of the inlet 3, with its gradually decreasing diameter along the fluid inflow direction, causes the water pressure to increase continuously as the fluid enters the inlet 3. This increases the torque of the rotating body 6, i.e., the impeller, making the impeller rotate more powerfully and further improving cleaning efficiency.

[0110] Optionally, in one implementation of this embodiment, such as Figures 1-3 As shown,

[0111] The self-cleaning structure further includes a second housing 103 connected and communicating with the housing 1, and a second water outlet 9 is formed on the second housing 103. The second water outlet 9 is used to discharge water that has entered the cleaning chamber 2 when the first water outlet 4 is closed, and at least a portion of the water that has entered the cleaning chamber 2 can be discharged through the second water outlet 9 after being filtered by the filter screen 5.

[0112] In this embodiment, the self-cleaning structure is a three-way structure, which includes three ports: inlet 3, first outlet 4, and second outlet 9. Washing water enters the cleaning chamber 2 through inlet 3 and is filtered by filter screen 5. The filter screen 5 can effectively filter lint in the washing water. Water flows out through the first outlet 4. The water in this flow path can be used for the washing machine spray circulation. The washing water in the other flow path is normally discharged through the second outlet 9. The arrangement of the second housing 103 and the second outlet 9 facilitates the discharge of scraped lint along the second housing 103 and the second outlet 9 under the action of fluid.

[0113] When the washing machine is draining, the filter screen 5 also filters the washing water, and the impeller can also rotate under the impact of the washing water. When a sensor is installed on the impeller to detect the rotation frequency of the impeller, it can be determined whether the filter screen 5 is severely clogged. If the impeller rotation frequency is low, it means that the filter screen is severely clogged. If the impeller rotation frequency is high, it means that the filter screen 5 is not severely clogged. Therefore, it can be determined whether the filter screen 5 needs to be further cleaned based on the impeller rotation frequency when the washing machine is draining.

[0114] Example 2

[0115] like Figure 4 As shown in this embodiment, a circulating spray assembly is provided, including:

[0116] The self-cleaning structure in Example 1;

[0117] Sprinkler piping;

[0118] The first water outlet 4 of the self-cleaning structure can be connected to the washing drum 14 of the clothing processing equipment through the spray pipe to form a circulating spray flow path.

[0119] The sprinkler piping includes:

[0120] Water supply pipe 10 is connected to water inlet 3;

[0121] The spray pipe 11 and the spray head are connected. One end of the spray pipe 11 is connected to the first water outlet 4, and the other end of the spray pipe 11 is connected to the spray head.

[0122] Drain pipe 16 is connected to the second outlet 9.

[0123] In this embodiment, a circulating spray assembly is formed by a self-cleaning structure and other components. The circulating spray assembly is used in a washing machine. Washing water enters the cleaning chamber 2 through the inlet 3 and is divided within the cleaning chamber 2. A portion of the washing water is filtered through the filter screen 5. The filter screen 5 can effectively filter lint from the washing water. The water flows out through the first outlet 4. The water in this flow path can be used for the washing machine spray cycle. That is, this flow path is operated by the pump body 12, so that the filtered washing water is transported to the spray head along the spray pipe 11. The spray head sprays the spray water into the washing drum 14 of the washing machine for the treatment of clothes, thereby improving the washing ratio of clothes, realizing the recycling of washing water, and saving water resources.

[0124] In Example 1, the self-cleaning structure is used in the circulating spray assembly, which can also prevent the lint spray pipe 11 from clogging through self-cleaning.

[0125] In Example 1, the self-cleaning structure is used in the circulating spray assembly. When the washing machine needs to use the circulating spray function, the rotating body 6, i.e., the impeller, rotates. In addition to cleaning the filter screen 5, it also acts as a second water pump. Through the rapid rotation of the impeller, the blades cause the washing water to rotate rapidly. The washing water is subjected to centrifugal force, and the rotating water flies out from the impeller, thereby realizing the rapid discharge of washing water from the second outlet 9. The self-cleaning structure is part of the washing machine's drainage path, and its structure is compact, simple, and low in cost.

[0126] More specifically, the circulating spray assembly is installed downstream of the drain outlet of the washing machine drum 14. The water supply pipe 10 is a flexible rubber connector, connected to both the drain outlet and the inlet 3 of the washing drum 14. Under normal circumstances, when the washing machine is washing clothes, water enters the washing drum 14 through the inlet box. When the circulating spray function is needed, the first water pump 12 pressurizes the water, causing the washing water, which has passed through the self-cleaning structure, to enter the spray pipe 11 from the first outlet 4. The spray head then sprays the water into the washing drum 14 for processing the clothes. When the washing machine does not need the circulating spray function, the first water pump 12 is turned off, and the washing water is discharged directly from the second outlet 9 through the drain pipe 16.

[0127] Optionally, in one implementation of this embodiment, such as Figure 5 As shown,

[0128] A first water pump 12 is installed on the spray pipe 11, and a second water pump 13 is installed on the water supply pipe 10 upstream of the water inlet 3. The first water pump 12 and the second water pump 13 are configured as follows:

[0129] When the first water pump 12 is controlled to be turned off and the second water pump 13 is controlled to be turned on, the water that enters the cleaning chamber 2 through the water supply pipe 10 can be discharged through the second water outlet 9.

[0130] When the first water pump 12 is turned on and the second water pump 13 is turned on, the water that enters the cleaning chamber 2 through the water supply pipe 10 can be sprayed out from the spray head through the spray pipe 11.

[0131] In this embodiment, the self-cleaning structure is installed at the rear end of the second water pump 13. When the second water pump 13 is started, the water in the washing drum 14 can be discharged. The discharged water forms a greater force, which makes the impeller in the self-cleaning structure rotate quickly. The scraper 702 will also rotate faster to scrape the side of the filter screen 5, thereby achieving self-cleaning of the filter screen 5. At the same time, the lint that is scraped off will also be discharged with the fluid through the second outlet 9 and the drain pipe 16 under the impact force of the second water pump's drainage.

[0132] Example 3

[0133] like Figure 4 , 5 As shown, this embodiment provides a garment processing device, including:

[0134] The washing drum 14 has an installation port at the upper end and a drain port at the lower end on its peripheral wall; a spray head is installed at the installation port.

[0135] Water supply pipe 10 connects to drain outlet and water inlet 3, and spray pipe 11 connects to first water outlet 4 and spray head;

[0136] The washing drum 14, water supply pipe 10, cleaning chamber, spray pipe 11 and spray head are connected in sequence to form a circulating spray flow path; the circulating spray flow path is used for circulating flowing water and spray washing.

[0137] Garment processing equipment also includes:

[0138] The main wash water inlet pipe 15 is used to inject washing water into the washing drum 14.

[0139] In this embodiment, during normal washing of clothes, the fluid enters the washing drum 14 through the main wash inlet pipe 15, and then exits through the water supply pipe 10, the second outlet 9, and the drain pipe 16. When the circulating spray function is required, the first water pump 12 pressurizes the water, causing the washing water that has passed through the self-cleaning structure to enter the spray pipe 11 from the first outlet 4. The spray head then sprays the water into the washing drum 14 for processing the clothes. The advantages of the self-cleaning structure in Embodiment 1 and the circulating spray assembly in Embodiment 2 are also present in this embodiment, and will not be repeated here.

[0140] In summary, the ingenious design of the self-cleaning structure lies in:

[0141] First, the self-cleaning structure is used in washing machines. Washing water enters the cleaning chamber through the inlet. The washing water is filtered through the filter screen to remove lint. As the fluid enters the self-cleaning structure, it impacts the cleaning components. Under the impact of the fluid, the cleaning components rotate rapidly and continuously scrape the side wall of the filter screen. This removes the lint trapped on the side wall of the filter screen by scraping, thus achieving the self-cleaning function. This self-cleaning structure is simple, requires no power supply, and is low in cost.

[0142] Secondly, the water inlet is designed to be located on the upper side of the rotating body. When the self-cleaning structure is used in a washing machine, the washing water impacts the rotating body under the action of gravity, which can further increase the rotation speed of the rotating body and improve the cleaning efficiency of the scraper on the side wall of the filter screen.

[0143] The design of the inlet, with its gradually decreasing diameter along the fluid flow direction, causes the water pressure to increase continuously as the fluid enters the inlet. This increases the torque of the rotating body, i.e., the impeller, making the impeller rotate more powerfully and further improving cleaning efficiency.

[0144] Third, the self-cleaning structure is used in the circulating spray assembly. Self-cleaning can also prevent the lint spray pipe from clogging. The spray head sprays water into the washing drum of the washing machine for the clothes to be processed, thereby improving the washing ratio of clothes, realizing the recycling of washing water and saving water resources.

[0145] The self-cleaning structure is used in the circulating spray assembly. When the washing machine needs to use the circulating spray function, in addition to cleaning the filter screen, it also acts as a second water pump. Through the rapid rotation of the impeller, the blades cause the washing water to rotate rapidly. The washing water is subjected to centrifugal force, and the rotating water flies out from the impeller, thereby realizing the rapid discharge of washing water from the second outlet. As part of the washing machine's drainage path, the self-cleaning structure is compact, simple, and low in cost.

[0146] Fourth, the self-cleaning structure is installed at the rear end of the second water pump. When the second water pump is running, it can discharge water from the washing drum. The discharged water forms a greater force, which makes the impeller in the self-cleaning structure rotate quickly. The scraper section will also rotate faster to scrape the side of the filter screen, thus achieving self-cleaning of the filter screen.

"And / or" describes the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can represent: A alone, A and B simultaneously, and B alone.
