[0061] Background

[0062] In fabric treatment equipment, such as washing machines, dryers, etc., the filtering and cleaning function of water flow is an important link to ensure the normal operation of the equipment and improve the fabric treatment effect. The traditional fabric treatment equipment usually sets a simple filtering device at the water inlet to intercept impurities in the water to prevent clogging of the nozzle or pipeline.

[0063] However, this single filtering method has some problems: on the one hand, the filtering device is easy to be clogged by impurities and needs to be cleaned or replaced frequently; on the other hand, once the filtering device fails, impurities may enter the interior of the equipment, affecting the service life of the equipment

[0064] Based on this, as Figures 1-10 shown, the first aspect of the embodiment of the present application provides a tee structure, comprising:

[0065] The tee front cover 20a is formed with a drain port 203 at one end in the axial direction and a front cover connecting structure 205 at the other end.

[0066] The three-way rear cover 20b is formed with a rear cover connecting structure 206 at one end in the axial direction and with a water inlet 202 at the other end;

[0067] The three-way front cover 20a is sealed and fitted together with the rear cover connecting structure 206 of the three-way rear cover 20b through the front cover connecting structure 205, and defines a three-way cavity 201 that communicates with the water inlet 202 and the drain 203;

[0068] The three-way front cover 20a and / or the three-way rear cover 20b is further formed with a backwash water inlet 204 that communicates with the three-way cavity 201, and the three-way cavity 201 is provided with a filter screen 60 that separates the three-way cavity 201 and is between the water inlet 202 and the backwash water inlet 204. The filter screen 60 includes opposite first and second screen surfaces, the first screen surface is arranged opposite the water inlet 202, and the second screen surface is arranged opposite the backwash water inlet 204;

[0069] The water flow entering the three-way cavity 201 through the water inlet 202 can be filtered when passing through the first screen surface of the filter screen 60, and the water flow entering the three-way cavity 201 through the backwash water inlet 204 can perform backwashing cleaning on the intercepted substances intercepted on the first screen surface when passing through the second screen surface of the filter screen 60.

[0070] The three-way structure in the embodiments of the present application integrates the water inlet, the drain, and the backwash water inlet in one structure through the design of the three-way cavity, so that the water flow can be reasonably distributed in the three-way cavity. At the same time, the arrangement of the filter screen not only improves the cleaning effect of the water flow, but also further improves the utilization efficiency of the water flow through the backwashing function, avoiding water flow waste.

[0071] Further, in some possible embodiments, the backwash water inlet 204 has a smaller diameter than the water inlet 202.

[0072] In this embodiment, because the diameter of the backwash inlet is smaller than that of the inlet, when water flows into the three-way chamber from the backwash inlet, the water velocity increases according to fluid mechanics principles, resulting in higher pressure. This high-pressure water flow can more effectively impact the impurities intercepted on the filter screen, loosening them and allowing them to be backwashed out, thereby improving the cleaning effect of the filter screen. This design ensures the high efficiency of the backwashing process, achieving good cleaning results even with a small water flow rate. Furthermore, the smaller diameter of the backwash inlet compared to the inlet allows for a more stable water flow distribution during normal operation of the three-way structure, where water enters from the inlet. Most of the water flows smoothly through the filter screen into the drain outlet without unnecessary diversion due to the excessively large diameter of the backwash inlet, thus ensuring the water flow efficiency and stability during normal operation. Additionally, since the backwash inlet is primarily used for backwashing the filter screen, the smaller diameter prevents large particles from entering the backwash inlet, avoiding clogging and further improving the reliability and service life of the three-way structure.

[0073] Furthermore, in some possible implementations, the water inlet direction of the backwash inlet 204 is tilted toward the second mesh surface of the filter screen 60.

[0074] In this embodiment, the backwash inlet is angled towards the second mesh surface of the filter screen, allowing the water flow to impact the filter screen surface at a more direct angle, thus more effectively removing impurities trapped on the first mesh surface. Compared to vertical or parallel water flow directions, this design allows for more concentrated rinsing of the filter screen, reducing impurity residue and improving backwashing efficiency. Furthermore, the angled inlet direction creates a certain swirling or turbulent effect after the water enters the three-way chamber, increasing the impact and shear forces of the water flow. This water flow characteristic helps to more thoroughly loosen and remove impurities from the filter screen while reducing the amount of water required for backwashing. Additionally, the angled water flow direction allows the backwash water to better cover the entire second mesh surface of the filter screen, avoiding insufficient rinsing in certain areas due to an undesirable water flow direction. This helps prevent impurities from accumulating on the filter screen, extending its service life. Simultaneously, the angled water flow direction allows the backwash water to utilize water energy more efficiently, reducing energy loss when entering the three-way chamber. This design not only improves backwashing efficiency but also reduces equipment operating costs.

[0075] Furthermore, in some possible embodiments, a pressure boosting plate 20121 is also provided inside the three-way cavity 201, and the pressure boosting plate 20121 is located between the backwash water inlet 204 and the filter screen 60.

[0076] The pressure plate 20121 is provided with several through holes 20122, which are used to pressurize the cleaning water flowing through the second screen of the filter screen 60 when the backwash water inlet 204 is filled.

[0077] The through-hole design on the pressure plate in this embodiment can divert and accelerate the water flow during backwashing, thereby increasing the impact force and pressure of the water flow. This pressurization effect allows the water flow to more effectively impact the filter screen, loosening and removing impurities trapped on the filter screen, improving backwashing efficiency. Furthermore, the through-hole design can evenly distribute the water flow onto the second mesh surface of the filter screen, ensuring that the entire filter screen surface is covered by the water flow. This uniform water flow distribution helps avoid the problem of insufficient local rinsing, further improving the thoroughness of backwashing. In addition, through the pressurization effect of the pressure plate, the backwashing process can achieve a more efficient cleaning effect with a lower water volume. This not only saves water resources but also reduces the operating cost of the equipment. Simultaneously, the pressure plate reduces the accumulation of impurities on the filter screen, thereby reducing the risk of filter screen clogging. At the same time, the uniform water flow impact also helps reduce local wear on the filter screen, extending its service life.

[0078] Furthermore, in some possible embodiments, the tee back cover 20b is provided with a backwash port 204, and the interior of the tee back cover 20b is provided with a pressure plate 20121 between the backwash port 204 and the filter screen 60.

[0079] In this embodiment, the pressure booster plate is located inside the T-junction back cover, near the backwash inlet, which more effectively pressurizes the backwash water flow. The through holes 20122 on the pressure booster plate can evenly distribute and accelerate the water flow, thereby creating a stronger impact force on the second screen of the filter screen and further improving backwashing efficiency. By setting the pressure booster plate inside the T-junction back cover, the water flow can obtain a certain pressurization effect before entering the T-junction cavity, thereby reducing the local resistance of the water flow when entering the filter screen. This design is similar to setting a flow straightener in the flow channel, which can optimize the flow field, reduce the formation of backflow zone, and reduce local resistance. Integrating the pressure booster plate inside the T-junction back cover reduces the installation space requirements of additional components, making the entire T-junction structure more compact. This design not only saves space but also improves the overall integrity and reliability of the system. The through hole design of the pressure booster plate can evenly distribute the water flow to the second screen of the filter screen, avoiding insufficient local rinsing caused by uneven water flow distribution. This uniform water flow distribution helps to more thoroughly remove impurities from the filter screen. Furthermore, integrating the pressure booster plate inside the tee's rear cover eliminates the need for additional pressure boosting devices or complex piping designs, reducing system complexity and manufacturing costs. This design simplifies installation and maintenance while improving system reliability.

[0080] Furthermore, in some possible implementations, the front cover connecting structure 205 includes a first slot formed on the axial end side of the tee front cover 20a, and the rear cover connecting structure 206 includes a first hook formed on the axial end side of the tee rear cover 20b. The first slot and the first hook engage together to fix the tee front cover 20a and the tee rear cover 20b together.

[0081] The front cover 20a and the rear cover 20b of the tee are also provided with sealing rings 207 at the mating positions. The sealing rings 207 are used to seal the connection position between the front cover 20a and the rear cover 20b of the tee.

[0082] In this embodiment, the front and rear covers of the tee can be quickly and reliably connected via a first slot and a first hook. This mechanical connection method is simple and easy to operate, requiring no additional fasteners, thus reducing assembly difficulty and cost. The snap-fit ​​structure provides sufficient mechanical strength to ensure that the tee structure will not loosen due to water flow impact or external force during use, thereby improving the stability and reliability of the entire tee structure. A sealing ring 207 is provided at the connection position of the front and rear covers of the tee, which effectively prevents water leakage from the connection point. The design of the sealing ring not only ensures the sealing of the tee cavity 201, but also avoids water waste and equipment failure caused by leakage. The sealing ring is usually made of elastic material, which can adapt to certain assembly errors and changes in working pressure, thereby maintaining good sealing performance under different working conditions. The matching method of the slot and hook, as well as the setting of the sealing ring, makes the assembly process of the front and rear covers of the tee simpler. This design reduces assembly steps and required tools, improving production efficiency. If the seal needs to be replaced or maintenance is required, this snap-fit ​​structure allows for quick disassembly and reassembly, reducing maintenance costs and time.

[0083] Furthermore, in some possible implementations, the tee cover 20b has a second groove 208 formed at one end of the inlet 202;

[0084] The tee structure also includes:

[0085] The filter cover 20c has a filter screen 60 and a second hook 209 that cooperates with the second slot 208.

[0086] The filter cap 20c is built into the back cover 20b of the tee and is fixed in the back cover 20b by the engagement of the second hook 209 and the second slot 208.

[0087] In this embodiment, the filter screen cover 20c is provided with a filter screen 60, which is engaged with the second slot 208 on the tee rear cover 20b via a second hook 209, thus fixing the filter screen cover inside the tee rear cover. This engagement method ensures that the filter screen remains stable under water flow impact and will not shift or fall off due to vibration or pressure changes. Furthermore, the engagement structure provides sufficient mechanical strength to ensure that the filter screen maintains good filtration performance during long-term use. The filter screen cover is fixed inside the tee rear cover via an engagement mechanism, making the installation and removal of the filter screen more convenient. Users can easily remove the filter screen cover for cleaning or replacement without complicated tools or operations. This removable design not only reduces maintenance costs but also improves equipment maintainability and reduces downtime caused by filter screen clogging or damage. The engagement between the filter screen cover and the tee rear cover creates a good seal, preventing water leakage from the connection. This sealing design not only improves the reliability of the tee structure but also reduces water waste caused by leakage. By integrating the filter screen onto the filter screen cap and securing it with a snap-fit ​​structure, this design further optimizes the internal layout of the three-way structure, reduces resistance when water flows through, and the stable installation of the filter screen and good sealing performance together improve the efficiency of the three-way structure in the filtration and backwashing process, ensuring the long-term stable operation of the equipment.

[0088] Furthermore, such as Figure 9 As shown, the second aspect of this application also provides a fabric processing device, which includes the three-way structure provided in the first aspect of this application.

[0089] In this embodiment, the filter screen in the three-way structure effectively intercepts impurities in the water, preventing them from entering the internal pipes and nozzles of the fabric processing equipment, thereby ensuring water cleanliness and improving washing performance. The design of the backwash inlet and filter screen gives the three-way structure a self-cleaning function. When water enters from the backwash inlet, it backwashes the filter screen, removing intercepted impurities, reducing the frequency of manual cleaning, and lowering maintenance costs. The three-way structure integrates the inlet, outlet, and backwash inlet into a single cavity, allowing for efficient water flow distribution and ensuring stable water flow during normal operation, while also maximizing water utilization during backwashing. The interception and backwashing functions of the filter screen reduce the possibility of impurities entering the equipment, lowering the risk of pipe blockage and extending the equipment's lifespan. The three-way structure design makes filter screen removal and cleaning more convenient; users can easily replace or clean the filter screen, reducing equipment maintenance time and costs. Because the three-way structure effectively prevents impurities from entering the equipment, it reduces equipment malfunctions caused by impurities, thereby lowering the frequency of maintenance. The three-way design, through its snap-fit ​​and sealing mechanism, ensures strong and secure connections between the front and rear covers, reducing malfunctions caused by loose connections or leaks. The backwashing function and pressure plate design minimize filter clogging, extending filter lifespan. The self-cleaning function of the three-way design reduces the frequency of filter cleaning, simplifying operation and improving user experience. The filter cap design allows users to select appropriate filter materials or pore sizes based on different water quality conditions, enhancing the equipment's adaptability.

[0090] In summary, applying the T-junction structure to fabric processing equipment significantly improves filtration and cleaning efficiency, optimizes water flow distribution, reduces maintenance costs, and enhances equipment reliability and lifespan. This integrated T-junction design not only improves the overall performance of the equipment but also provides users with a more convenient and efficient user experience.

[0091] Furthermore, in some possible embodiments, the fabric treatment equipment includes a fabric treatment cylinder 10 and a spray pipeline;

[0092] The spray pipeline includes an inlet pipe 30 and a drain pipe 40. The inlet pipe 30 is connected to the inlet 202, and the drain pipe 40 is connected to the drain 203. The end of the inlet pipe 30 away from the inlet 202 and the end of the drain pipe 40 away from the drain 203 are both connected to the fabric treatment cylinder 10. A spray pump 50 is provided on the spray pipeline. When the spray pump 50 is turned on, the washing water in the fabric treatment cylinder 10 can enter the three-way cavity 201 through the inlet pipe 30 and can be discharged back into the fabric treatment cylinder 10 through the drain pipe 40, so that the fabric treatment equipment can operate in a cycle of spray washing.

[0093] The filter screen 60 divides the three-way cavity 201 into a first cavity 2011 and a second cavity 2012 connected by the filter screen holes. The first cavity 2011 is connected to the water inlet pipe 30, and the second cavity is connected to the drain pipe 40 and the backwash water outlet 204. The washing water that enters the first cavity 2011 through the water inlet pipe 30 can be filtered by the filter screen 60 and flow into the second cavity 2012, and is discharged through the drain pipe 40 connected to the second cavity 2012.

[0094] The spray pipeline also includes a backwash water pipe 70. One end of the backwash water pipe 70 is connected to the backwash water inlet 204, and the other end is connected to the water inlet valve 80. When the water inlet valve 80 is opened, the spray pump 50 is closed, so that while the circulating spray washing stops, the cleaning water enters the second chamber 2012 through the backwash water pipe 70 and enters the first chamber 2011 through the filter screen 60 to perform backwash cleaning on the filter screen 60.

[0095] In this embodiment, by setting a three-way structure 20 in the fabric processing equipment and connecting the three-way structure 20 to different pipelines, the fabric processing equipment can both filter the washing water through the filter screen 60 during circulating spray washing and perform backwashing self-cleaning of the filter screen 60 when it becomes clogged, thus eliminating the need for manual cleaning of the lint on the filter screen 60.

[0096] Specifically, when the fabric treatment equipment needs to operate in a circulating spray washing mode, the spray pump 50 is turned on and the inlet valve 80 is closed. At this time, the washing water in the fabric treatment drum 10 enters the three-way structure 20 through the inlet pipe 30, and after being filtered by the filter screen 60 in the three-way structure 20, it is discharged back into the fabric treatment drum 10 through the drain pipe 40, thereby achieving the circulating spray washing effect of the fabric treatment equipment.

[0097] More specifically, when the filter screen 60 becomes clogged, the spray pump 50 is turned off to stop the circulating spray washing, and the water inlet valve 80 is opened at the same time. Since the drain pipe 40 is closed at this time, the cleaning water that enters the three-way structure 20 through the water inlet valve 80 will flow to one side of the water inlet pipe 30, thereby achieving backwashing and cleaning of the filter screen 60, thus achieving the self-cleaning effect of the filter screen 60.

[0098] Furthermore, in some possible embodiments, the fabric treatment device further includes:

[0099] Sensor 90 is used to acquire and output parameter values ​​that characterize the degree of clogging of filter 60;

[0100] The controller is used to control the opening and closing of the spray pump 50 and the inlet valve 80 according to parameter values.

[0101] In this embodiment, by obtaining the dirt and clogging value of the filter screen 60, the opening and closing of the spray pump 50 and the water inlet valve 80 can be automatically controlled, thereby realizing the automatic detection and automatic cleaning effect of the dirt and clogging degree of the filter screen 60.

[0102] Specifically, in some possible implementations, such as Figure 9 As shown, the sensor includes a water flow sensor installed on the inlet pipe 30 and / or the drain pipe 40. The controller is used to control the opening and closing of the spray pump 50 and the opening and closing of the inlet valve 80 based on the water flow parameter value obtained by the water flow sensor.

[0103] In this embodiment of the application, by obtaining the flow rate of circulating water during the circulating spray washing, it is possible to indirectly reflect whether the filter screen is clogged.

[0104] Specifically, when the water flow rate is low, it indicates that the filter screen is clogged and needs to be cleaned. When the water flow rate is high, it indicates that the filter screen is not clogged and does not need to be cleaned.

[0105] Preferably, when the water flow sensor is installed on the drain pipe 40, it can more accurately detect the dirt and clogging of the filter screen.

[0106] Furthermore, in some possible implementations, a drain assembly 300 is also connected to the water inlet pipe 30, wherein the drain assembly 300 is controlled to open when the spray pump 50 is closed and / or the water inlet valve 80 is opened.

[0107] In this embodiment of the application, when the filter screen 60 is backwashed, the cleaning water can be discharged through the drain assembly 300, thereby preventing the cleaning water from flowing back into the fabric treatment cylinder 10. The drain assembly includes a drain connector 301 and a drain valve 302. The opening and closing of the drain assembly 300 is achieved by controlling the opening and closing of the drain valve 302.

[0108] Furthermore, in some possible implementations, one end of the inlet pipe 30 away from the inlet 202 is connected to the bottom of the fabric treatment tube 10;

[0109] One end of the drain pipe 40 away from the drain outlet 203 is connected to the top of the fabric treatment cylinder 10 and is equipped with a spray head;

[0110] The spray pump 50 is a booster pump installed on the drain pipe 40, used to pump the washing water discharged from the bottom of the fabric treatment cylinder 10 back into the fabric treatment cylinder 10 from the top of the fabric treatment cylinder 10.

[0111] Sensor 90 is located between the three-way structure 20 and the spray pump 50 to obtain the water flow rate parameter value in the drain pipe 40.

[0112] In this embodiment, by setting the spray pump 50 as a booster pump connected to the drain pipe 40, compared with the existing method of achieving the circulating spray washing effect through the drain pump, setting the booster pump on the drain pipe 40 can increase the spray water pressure during circulating spray washing and improve the spray washing effect on the underwear in the fabric treatment drum 10.

[0113] Furthermore, the third aspect of this application also provides a method for treating filter clogging in a fabric treatment device, which is applied to the fabric treatment device provided in the second aspect of this application. The fabric treatment device has a circulating spray washing program. Under the circulating spray washing program, the spray pump is controlled to be turned on and the inlet valve is controlled to be closed. The washing water in the fabric treatment drum can enter the three-way cavity through the inlet pipe, and after being filtered by the filter screen in the three-way cavity, it is pumped back to the fabric treatment drum through the drain pipe.

[0114] Methods for dealing with clogged filters include:

[0115] Under the circulating spray washing program;

[0116] Obtain parameter values ​​to characterize the filter screen's clogging status, and control the opening and closing of the spray pump and the inlet valve based on these parameter values.

[0117] In this embodiment, by obtaining the dirt and clogging value of the filter screen 60, the opening and closing of the spray pump 50 and the water inlet valve 80 can be automatically controlled, thereby realizing the automatic detection and automatic cleaning effect of the dirt and clogging degree of the filter screen 60.

[0118] Furthermore, in some possible implementations, controlling the opening and closing of the spray pump and the inlet valve based on parameter values ​​includes:

[0119] If the parameter values ​​meet the requirements, control the opening and closing of the spray pump and the closing of the water inlet valve to continue the circulating spray washing program.

[0120] If the parameter values ​​do not meet the requirements, the spray pump is turned off and the inlet valve is turned on, so that while the circulating spray washing stops, cleaning water is injected into the three-way cavity through the backwash water pipe to backwash the filter screen.

[0121] When the filter screen becomes dirty and clogged, the circulating spray is stopped to perform a backwash cleaning of the filter screen. When the filter screen is not dirty and clogged, the circulating spray washing continues to operate, so as to improve the washing effect on the fabric of the tubular clothing.

[0122] Furthermore, in some possible implementations, the filter clogging treatment method also includes:

[0123] When the inlet valve is open and the spray pump is closed, the drainage assembly is activated.

[0124] In this embodiment of the application, when the filter screen 60 is backwashed, the cleaning water can be discharged through the drain assembly 300, thereby preventing the cleaning water from flowing back into the fabric treatment cylinder 10. The drain assembly includes a drain connector 301 and a drain valve 302. The opening and closing of the drain assembly 300 is achieved by controlling the opening and closing of the drain valve 302.

[0125] Furthermore, in some possible implementations, obtaining parameter values ​​used to characterize the filter clogging status includes:

[0126] Obtain the water flow rate value in the drain pipe, and control the opening and closing of the inlet valve and the spray pump based on the water flow rate value.

[0127] If the water flow rate is less than the preset water flow rate, the inlet valve will be opened and the spray pump will be shut down.

[0128] If the water flow rate is greater than or equal to the preset water flow rate, the inlet valve will be closed and the spray pump will be turned on.

[0129] In this embodiment of the application, by obtaining the flow rate of circulating water during the circulating spray washing, it is possible to indirectly reflect whether the filter screen is clogged.

[0130] Specifically, when the water flow rate is low, it indicates that the filter screen is clogged and needs to be cleaned. When the water flow rate is high, it indicates that the filter screen is not clogged and does not need to be cleaned.

[0131] Furthermore, in some possible implementations, the fabric treatment equipment also has a drainage procedure executed after the cyclic spray washing program has run, in which the drainage component is controlled to open and the spray pump is controlled to close, so as to discharge the washing water in the fabric treatment drum through the drainage component while stopping the cyclic spray washing.

[0132] Methods for dealing with clogged filters also include:

[0133] During the drainage process, the inlet valve is opened to inject cleaning water into the three-way chamber through the backwash water pipe to perform backwash cleaning of the filter screen.
