Description

Technical Field

[0001] The present invention belongs to the technical field of laundry equipment, and specifically relates to a lint filtering device installed externally, a washing system, and a control method.

Background Art

[0002] Laundry equipment for washing clothes, such as a washing machine, has friction between clothes and between clothes and the washing machine body during the washing of clothes, so lint is generated and shed from the clothes and mixed into the washing water. If these lint are directly discharged together with the drainage of the washing machine, there is a potential risk that the sewer will be blocked after a long time. Therefore, a filter for filtering lint is installed inside a conventional washing machine, and lint can be removed from the drainage water flow before drainage.

[0003] However, filtered foreign matters such as lint after filtration continuously accumulate in the filter. In some conventional washing machines, the user needs to regularly remove the filter for cleaning and reinstall the filter in the washing machine after cleaning. When the filter is installed inside the washing machine, the operations of removing and reinstalling the filter are relatively cumbersome. In addition, the filter occupies a certain space inside the washing machine and affects the overall dimensions of the washing machine. Furthermore, if the washing machine in the user's home does not have a filtering function, the user has no choice but to purchase a new washing machine.

[0004] Meanwhile, in recent years, the concept of microplastics has been proposed in the field of environmental protection and is gaining increasing importance. Research has revealed that one of the major sources of microplastics is wastewater discharged from household washing machines. This is because, with the widespread use of synthetic fiber fabrics, clothing fibers shed during washing are discharged with the washing machine's wastewater, becoming microplastics that contaminate the natural water environment. Microplastics enter the ecological cycle directly with the wastewater, and through the natural biological chain, they can eventually accumulate in the human body and potentially affect human health. For this reason, some regions have established relevant standards regarding the amount of microplastics in washing machine wastewater. Conventional washing machines may not have filtration accuracy that meets the filtration requirements for microplastics. In this case as well, users will need to purchase a new washing machine to solve the problem of direct discharge of wash water.

[0005] Therefore, a filtration device that can be directly applied to conventional washing equipment is needed, which would allow users to achieve filtration of the drain water flow without replacing their household washing equipment. However, at the same time, even if a user installs an additional filtration device on top of their conventional washing equipment, if the washing program is run with the device not properly installed, an effective filtration function cannot be achieved.

[0006] In view of the above, the present invention is proposed. [Overview of the project] [Problems that the invention aims to solve]

[0007] The technical problem that this invention aims to solve is to overcome the shortcomings of the prior art and provide an externally installed lint filter, a washing system, and a control method.

[0022] A second object of the present invention is to provide a control method and a washing system for a washing system capable of realizing interlocking control between a washing facility and a lint filtering device installed outside, thereby preventing the problem that the lint filtering device is not properly installed and effective filtering cannot be achieved even when the washing facility is in operation. Specifically, the following technical ideas are adopted.

[0023] A control method for a washing system, wherein the aforementioned washing system includes a washing facility and a lint filtering device installed outside the aforementioned washing facility.

[0024] Furthermore, it is determined whether the water intake of the lint filtering device is properly connected to the water outlet end of the drainage pipeline, and the washing facility controls whether to permit the operation of the washing program based on the determination result.

[0025] Furthermore, the washing facility receives an operation command for the washing program and determines whether the water intake of the lint filtering device is properly connected to the water outlet end of the drainage pipeline.

[0026] If it is determined that the water intake of the lint filtering device is properly connected to the water outlet end of the drainage pipeline, the washing facility starts the operation of the washing program, and / or if it is determined that the water intake of the lint filtering device is not properly connected to the water outlet end of the drainage pipeline, the washing facility prohibits the operation of the washing program.

[0027] Furthermore, after receiving an operation command for the washing program, the washing facility sends a detection request to the lint filtering device.

[0028] The aforementioned lint filtering device receives the aforementioned detection request and feeds back a detection signal to the washing facility.

[0029] The washing facility determines whether the water intake of the lint filtering device is properly connected to the water outlet end of the drainage pipeline based on the received detection signal.

[0030] Furthermore, if the washing machine determines during the operation of a washing program that the intake of the lint filter is not properly connected to the outlet of the drain pipe, it will interrupt the operation of the current washing program.

[0031] Furthermore, if the washing machine determines that the intake of the lint filter is properly connected to the outlet of the drain pipe, it will maintain the current washing program and continue operation.

[0032] Furthermore, during the operation of the washing program, the washing equipment determines, based on detection signals transmitted from the lint filter, whether the intake of the lint filter is properly connected to the outlet of the drain pipe.

[0033] Furthermore, a detection element is installed on the aforementioned lint filtration device, and a detection element is installed at the outlet end of the aforementioned drainage pipe. If the distance between the detection element and the detection element is less than a predetermined distance, the detection element is triggered.

[0034] The aforementioned lint filter and / or washing equipment acquires that the aforementioned detection element is in a triggered state, and the aforementioned washing equipment permits the operation of the washing program.

[0035] Furthermore, the aforementioned detection element includes a magnetically sensitive element, the aforementioned detected element includes a magnetic component, and the aforementioned magnetically sensitive element can be triggered by an approaching magnetic component.

[0036] The aforementioned lint filter and / or washing equipment detects that the aforementioned magnetically sensitive element is in a triggered state, and the aforementioned washing equipment permits the operation of the washing program.

[0037] A washing system comprising washing equipment and a lint filtration device. The aforementioned washing system is subject to the aforementioned washing system control method.

[0038] A third objective of the present invention is to provide a washing system control method and a washing system that can achieve coordinated control between the washing equipment and an externally installed lint filtration device, thereby acquiring the connection status of the lint filtration device at a specific operating stage and preventing problems such as water leakage and inability to perform filtration due to improper connection of the lint filtration device. Specifically, the following technical concept is adopted.

[0039] A method for controlling a washing system, wherein the washing system comprises a washing machine and a lint filter installed outside the washing machine, the washing machine comprises a drainage pipe for draining water to the outside, and the lint filter comprises a water intake.

[0040] The aforementioned control method is The washing machine runs the washing program, This includes determining whether a preset operating stage has been reached and whether the intake of the lint filter is properly connected to the outlet of the drainage pipe.

[0041] Furthermore, the aforementioned pre-set operating stages include the draining stage of the washing program.

[0042] If, upon reaching the aforementioned drainage stage, it is determined that the intake of the lint filter is not properly connected to the outlet of the drainage pipe, drainage to the outside is interrupted, and / or, upon reaching the aforementioned drainage stage, it is determined that the intake of the lint filter is properly connected to the outlet of the drainage pipe, drainage to the outside is maintained.

[0043] Furthermore, when the aforementioned drainage stage is reached, the washing equipment acquires information on the operating status of the lint filter and determines, based on the aforementioned operating status information, whether the intake of the lint filter is properly connected to the outlet of the drainage pipe.

[0044] Furthermore, the operating status information of the lint filter device mentioned above includes water intake information for the lint filter device. When the washing equipment determines, based on the aforementioned water intake information, that the wastewater flow in the drain pipe has entered the lint filter device, it determines that the water intake of the lint filter device is properly connected to the outlet end of the drain pipe.

[0045] Furthermore, the aforementioned water intake information includes information on the water flow rate through the lint filter. In the aforementioned drainage stage, if the washing equipment acquires the aforementioned water flow rate information and confirms that there is a water flow passing through the lint filter, it determines that the intake port of the lint filter is properly connected to the outlet end of the drainage pipe.

[0046] Furthermore, the aforementioned water intake information includes the water level information inside the lint filter. During the drainage stage, if the washing equipment acquires the aforementioned water level information and confirms that there is water inside the lint filter, it determines that the water intake of the lint filter is properly connected to the outlet of the drainage pipe.

[0047] Furthermore, when the aforementioned washing equipment runs the washing program and reaches the draining stage, it begins the operation of draining the water to the outside.

[0048] If the washing equipment receives water intake information indicating that the wastewater flow has entered the lint filter within a predetermined time, it will maintain a state where it continues to drain water to the outside.

[0049] Furthermore, if the washing equipment initiates an external drainage operation and, after a predetermined time has elapsed, does not continuously acquire water intake information indicating that the drainage water flow has entered the lint filter, the external drainage operation will be interrupted.

[0050] Furthermore, when the washing machine runs the washing program and reaches a preset operating stage, it sends a detection request to the lint filter.

[0051] The aforementioned lint filtration device receives the aforementioned detection request and transmits the current operating status information to the washing equipment.

[0052] Based on the received operating status information, the washing equipment determines whether the intake of the lint filter is properly connected to the outlet of the drain pipe.

[0053] A washing system comprising washing equipment and a lint filtration device. The aforementioned washing system is subject to the aforementioned washing system control method. [Effects of the Invention]

[0054] By adopting the above technical concept, the present invention has the following beneficial effects compared to the prior art.

[0055] In this invention, the lint filter can be externally connected to the laundry equipment, and the filtration function is achieved without fundamentally altering the original structure of the laundry equipment. By installing a detection module, it is possible to detect whether the water intake port for water intake is properly connected to the external connection pipeline. This avoids the problem of water leakage failures occurring when the water intake port is not properly connected, and at the same time prevents the problem of the lint filter not being able to perform its effective filtration function because the water to be filtered does not enter the lint filter. Furthermore, since the lint filter is externally connected on the drain pipeline of the laundry equipment, and the wastewater from the laundry equipment is discharged after being filtered, it avoids the problem of filtered foreign matter such as lint in the wastewater flow clogging the sewer, and also prevents adverse effects caused by microplastics accompanying the wastewater from the laundry equipment directly entering the ecological cycle with the wastewater flow.

[0056] In this invention, the washing machine can be linked to a lint filter, thereby controlling whether to allow the operation of the washing program based on whether the lint filter is connected to the drain pipe. This avoids the problem of water leakage failure occurring at the intake of the lint filter, and also prevents the problem of the washing machine's wastewater not entering the lint filter, thus preventing the filtration function from being effectively realized. Specifically, the washing machine can acquire the connection status between the lint filter and the drain pipe before activating the washing program. This ensures that the washing program is activated only when the intake of the lint filter is properly connected to the outlet of the drain pipe, thereby guaranteeing that the lint filter can effectively perform its filtration function. Furthermore, the connection status between the lint filter and the drain pipe can also be acquired during operation. If a connection abnormality occurs, the washing program is interrupted, preventing problems such as water leakage or inability to filter that may occur if the washing program continues to run.

[0057] In this invention, the washing equipment can be linked with a lint filter, and the connection status between the lint filter and the drain pipe is acquired at a specific operating stage. This ensures that the intake of the lint filter is properly connected to the outlet of the drain pipe, helping to prevent problems such as water leakage and inability to filter that may occur if the connection is not made properly. Specifically, the lint filter is designed to provide a filtration effect on the wastewater flow of the washing equipment. The washing equipment acquires the connection status between the lint filter and the drain pipe at the drainage stage, and if it determines that the connection is not made properly, it interrupts drainage. This effectively prevents the problem of wastewater leaking from the intake of the lint filter and entering the lint filter, thus preventing filtration. Furthermore, the washing equipment determines whether the wastewater flow is entering the lint filter by acquiring the water flow rate or water level inside the lint filter, and also determines whether the intake of the lint filter is properly connected to the outlet of the drain pipe. This allows for the timely and accurate determination of the connection status between the lint filter and the drainage pipe without requiring a complex detection structure.

[0062] In describing this invention, unless otherwise explicitly defined or limited, the terms "attach," "connect," and "connect" should be understood in a broad sense. For example, a connection may be fixed, detachable, or integral. Furthermore, a connection may be mechanical or electrical.

[0063] As shown in Figures 1 to 4, this embodiment provides an externally installed lint filter 20 and a washing system having the aforementioned lint filter 20.

[0064] Specifically, the lint filter 20 of this embodiment includes a filtration module 600, and the lint filter 20 has a water intake 22 that communicates with the filtration module 600. The water intake 22 is connected to an external connection pipeline, and water to be filtered is sent to the lint filter 20 via the external connection pipeline, where the filtration module 600 receives the water and performs filtration. The lint filter 20 further includes a detection module, which can be used to detect whether the water intake 22 is properly connected to the external connection pipeline.

[0065] In the above configuration, the lint filter 20 can be connected to a pipeline where water flow filtration is required, and the water flow to be filtered can be filtered through the lint filter 20. By installing a detection module, it is possible to confirm that the intake port 22 of the lint filter 20 is properly connected to the external connection pipeline, thus avoiding problems such as water leakage at the intake port 22 or the inability to perform filtration due to the water flow not entering the lint filter 20 if the two are not properly connected.

[0066] The washing system described in this embodiment specifically includes the lint filtration device 20 described above, and further includes washing equipment 10. It should be noted that the aforementioned washing equipment 10 may be a home appliance capable of performing clothing washing functions, such as a washing machine, a washer-dryer, or a garment care machine.

[0067] Specifically, the washing equipment 10 is equipped with a drainage pipe 250 for draining water to the outside, and the outlet end 251 of the drainage pipe 250 is connected to the intake port 22 of the lint filter 20. In other words, when the lint filter 20 of this embodiment is applied to the above washing system, the drainage pipe 250 of the washing equipment 10 is an external connection pipe connected to the intake port 22.

[0068] In the above configuration, the lint filter 20 is installed outside the washing equipment 10 and directly connected to the drainage pipe 250 of the washing equipment 10. It does not occupy the internal space of the washing equipment 10 and does not fundamentally change the structure of the washing equipment 10, while still providing a filtration function for the drainage water flow of the washing equipment 10.

[0069] In detail, in this embodiment, the washing equipment 10 is equipped with a water receiving tank 100, and the washing equipment 10 has a water intake pipe 290 for drawing water into the water receiving tank 100. The water intake end of the drainage pipe 250 is connected to the water receiving tank 100, and a drainage pump 400 is installed on the drainage pipe 250. When the washing equipment 10 requires drainage, the drainage pump 400 is activated to discharge the water in the water receiving tank 100 along the drainage pipe 250.

[0070] The lint filter 20 further has an outlet 23 that communicates with the filtration module 600. The water flow discharged along the drainage pipe 250 enters the lint filter 20 from the intake 22, is sent to the filtration module 600 along the internal flow path of the lint filter 20 for filtration, and the filtered water is finally discharged from the outlet 23. A discharge pipe 24 is connected to the outlet 23, and the discharge pipe 24 can be directly connected to the floor drain in the user's home, allowing filtered water free of lint and other filtered foreign matter to flow directly into the floor drain.

[0071] In the above configuration, the lint filter 20 is installed outside the washing machine 10 and directly connected to the drainage pipe 250 of the washing machine 10. It does not occupy the internal space of the washing machine 10 and does not fundamentally change the structure of the washing machine 10, while still providing a filtration function for the drainage water flow of the washing machine 10. After the drainage water flow of the washing machine 10 is filtered through the lint filter 20, it flows into the floor drain, avoiding the problem of the floor drain becoming clogged with lint in the drainage water flow.

[0072] Furthermore, the lint filtration device 20 of this embodiment further includes a communication module, which can directly transmit the detection results from the detection module via the aforementioned communication module.

[0073] Specifically, the lint filter 20 is connected to the washing machine 100 via the aforementioned communication module, and can directly transmit the detection results from the detection module to the washing machine 10. This allows the washing machine 10 to know whether the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drainage pipe 250 of the washing machine 10. In this way, the washing machine 10 can be controlled to allow the operation of the washing program only when the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drainage pipe 250, thus avoiding problems such as water leakage and inability to perform filtration that may occur if the connection is not made properly.

[0074] In a further embodiment of this model, the aforementioned detection module is installed at the intake port 22, or in an area close to the intake port 22 on the lint filter 20. The aforementioned detection module can be triggered if the distance between the external connection pipeline, i.e., the outlet port 251 of the drainage pipeline 250 in this model, and the intake port 22 is less than a preset distance. At this time, it can be confirmed that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drainage pipeline 250, and the wastewater flow in the drainage pipeline 250 enters from the intake port 22 and flows through the filtration module 600 to achieve filtration.

[0075] Furthermore, the lint filtration device 20 of this embodiment is equipped with an outer casing 21, the filtration module 600 is installed inside the outer casing 21, and a water intake port 22 communicating with the filtration module 600 is provided on the outer casing 21. The aforementioned detection module is equipped with a detection element installed on the outer casing 21, and a detected element corresponding to the aforementioned detection element is installed at the water outlet end 251 of the drainage pipe 250. When the detected element approaches the aforementioned detection element, the aforementioned detection element can be triggered to generate a trigger signal.

[0076] In this embodiment, the detection element is a magnetically sensitive element installed on the outer casing 21 in an area close to the water intake 22. A magnetic component 810 is installed at the outlet end 251 of the drainage pipe 250, and when the water intake 22 is properly connected to the outlet end 251 of the drainage pipe 250, the outlet end 251 comes into contact with the outer casing 21. This causes the magnetic component 810 to approach the magnetically sensitive element, triggering the magnetically sensitive element and generating a trigger signal.

[0077] It should be understood that the aforementioned magnetic sensing element may be installed directly at the intake location, for example, on the inner wall of the intake. Even when the outlet end of the drainage pipe is connected to the intake with a magnetic component, the magnetic component can approach the aforementioned magnetic sensing element, triggering the magnetic sensing element and generating a trigger signal.

[0078] In detail, the magnetically sensitive element in this embodiment is a reed switch 820, and a signal output line 823 is connected to the magnetically sensitive element to the communication module of the lint filter 20 for sending the aforementioned trigger signal. The first electrode 821 and the second electrode 822 inside the reed switch 820 do not normally make contact; that is, the reed switch 820 is in a non-triggered state.

[0079] When the outlet end 251 of the drainage pipe 250 is properly connected to the intake port 22 of the lint filter 20, the magnetic component 810 approaches the reed switch 820, and the magnetic force generated by the magnetic component 810 deforms the first electrode 821 and the second electrode 822, causing them to come into contact. At this time, the reed switch 820 is in a conductive trigger state, generates a trigger signal, and transmits it to the communication module via the signal output line 823.

[0080] On the other hand, once the connection between the outlet end 251 and the intake 22 of the drain pipe 250 is disconnected, the magnetic component 810 separates from the reed switch 820, and the first electrode 821 and the second electrode 822 return to a non-contact state. At this time, the lint filter 20 and the washing equipment 10 can obtain a signal indicating that the reed switch 820 is in a non-triggered state, thereby confirming that a connection abnormality has occurred between the lint filter 20 and the drain pipe 250.

[0081] In another specific embodiment of this design, the aforementioned drainage pipe is inserted and connected to the intake of a lint filter. The aforementioned detection element is a touch switch installed on the intake, and the aforementioned detected element is a trigger unit installed at the outlet end of the drainage pipe.

[0082] In one detailed embodiment, the outlet end of the drainage pipe is inserted into the intake to establish a connection, the aforementioned touch switch is installed on the inner wall of the intake, and the aforementioned trigger is a projection structure installed on the outer wall of the outlet end, or the end face of the outlet end. When the outlet end of the drainage pipe is properly inserted into the intake, the aforementioned touch switch is triggered, generating a trigger signal.

[0083] In a more detailed variant, the outlet end of the drainage pipe is fitted and connected to the aforementioned intake to achieve the connection. The aforementioned touch switch is installed on the outer wall of the intake, and the aforementioned trigger is a projection structure installed on the inner wall of the aforementioned outlet end, or the end face of the aforementioned outlet end. When the outlet end of the drainage pipe is fitted and connected to the aforementioned intake and properly installed, the aforementioned touch switch can be triggered to generate a trigger signal.

[0084] It should be explained that in this embodiment, the lint filter 20 may self-determine the connection status between the water intake 22 and the outlet 251 of the drain pipe 250 based on whether the detection module has been triggered, and transmit this information to the washing machine 10. Alternatively, the lint filter 20 may directly transmit information to the washing machine 10 indicating whether the detection module has been triggered, and the washing machine 10 may determine, based on the received information, whether the water intake 22 of the lint filter 20 is properly connected to the outlet 251 of the drain pipe 250. Or, the lint filter 20 and the washing machine 10 may each be connected to a cloud server, the lint filter 20 may transmit information to the cloud server indicating whether the detection module has been triggered, the cloud server may determine whether the water intake 22 of the lint filter 20 is properly connected to the outlet 251 of the drain pipe 250, and transmit the corresponding information or control command to the washing machine 10.

[0085] In a further embodiment of this example, the aforementioned filtration module 600 can filter out filtration impurities larger than 50 μm in size. The aforementioned filtration impurities may include microplastics. In particular, the filtration impurities may include plastic fibers that are longer than 50 μm and have a diameter of 10 to 1000 μm. Preferably, the aforementioned plastic fibers have a length of 400 to 600 μm, with the most common length in the distribution being 500 μm ± 50 μm. The diameter of these plastic fibers is preferably 10 to 50 μm, with the most common having a diameter of 17 μm ± 2 μm.

[0086] By controlling the filtration accuracy of the filtration module 600 within the above range, microplastics in the wastewater from the washing equipment 10 can be filtered out as thoroughly as possible, ultimately ensuring that the microplastic content in the water discharged from the outlet 23 meets the direct release standards. In this way, the washing equipment 10 can discharge wastewater directly to the outside, eliminating concerns about microplastics being discharged with the wastewater flow and entering the ecological cycle.

[0087] In this embodiment, the lint filter 20 provided can be externally connected to the drain pipe 250 of the washing machine 10, does not occupy the internal space of the washing machine 10, and realizes a drainage filtration function without changing the internal structure of the washing machine 10, solving the problems of clogging of the floor drain and the ease with which microplastics enter the ecological cycle, which occur when the washing machine 10 directly drains water without a filtration function. The lint filter 20 has a detection module, and using the aforementioned detection module, the washing machine 10 can acquire the connection status between the lint filter 20 and the drain pipe 250. In this way, the washing machine 10 can control its own operating state based on the aforementioned connection status acquired, and the washing machine 10 can operate the washing program only when the lint filter 20 is correctly installed, i.e., when the water intake 22 is properly connected to the water outlet 251 of the drain pipe 250, and ensures that the lint filter 20 can achieve an effective filtration function. [Examples]

[0088] This embodiment provides a method for controlling a washing system.

[0089] As shown in Figure 1, the laundry system according to this embodiment comprises a laundry machine 10 and a lint filter 20 installed outside the laundry machine 10. The laundry machine 10 is equipped with a drain pipe 250 for draining water to the outside, and when the outlet end 251 of the drain pipe 250 is connected to the intake port 22 of the lint filter 20, the laundry machine 10 allows the operation of the laundry program. It should be noted that the aforementioned laundry machine 10 may be a home appliance capable of performing clothing washing functions, such as a washing machine, a washer-dryer, or a garment care machine.

[0090] In this embodiment, the lint filter 20 is for realizing the drainage filtration function of the washing equipment 10, and the washing equipment 10 allows the operation of the washing program only when the outlet end 251 of the drainage pipe 250 is connected to the intake port 22 of the lint filter 20, ensuring that the drainage water flow from the washing equipment 10 can enter the lint filter 20 and be filtered.

[0091] Furthermore, in the laundry system of this embodiment, the laundry equipment 10 and the lint filter 20 are connected by communication, enabling coordinated control of both. This allows the laundry equipment 10 to be controlled to allow the operation of the laundry program only when the lint filter 20 is effectively connected to the drain pipe 250.

[0092] The aforementioned "effectively connected" means that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drainage pipe 250, that all of the wastewater flow in the drainage pipe 250 can enter the lint filter 20 from the intake port 22, and that no water leakage occurs at the connection point.

[0093] Specifically, as shown in Figures 1 to 4, the control method of this embodiment is applied to the washing system provided in Embodiment 1 above. The aforementioned control method is To determine whether the intake port 22 of the lint filter 20 is properly connected to the outlet end 251 of the drainage pipe 250, This includes controlling whether the washing equipment 10 allows the operation of the washing program based on the determination result.

[0094] In the above configuration, if the washing machine 10 determines that the water intake 22 of the lint filter 20 is properly connected to the outlet 251 of the drain pipe 250, it permits the operation of the washing program; otherwise, it does not permit the operation of the washing program. In this way, the washing machine 10 avoids problems such as water leakage or inability to perform drain filtration when the washing machine 10 drains water to the outside, which would occur if the washing machine 10 were to operate the washing program while there is an abnormality in the connection between the lint filter 20 and the drain pipe 250.

[0095] As shown in Figure 5, in a further embodiment of this model, the aforementioned control method specifically involves: The washing equipment 10 receives a command to operate the washing program and determines whether the water intake of the lint filter is properly connected to the water outlet of the drain pipe. When the washing equipment 10 determines that the water intake 22 of the lint filter 20 is properly connected to the water outlet 251 of the drain pipe 250, it starts operating the washing program. The washing equipment 10 includes prohibiting the operation of the washing program if it determines that the intake port 22 of the lint filter 20 is not properly connected to the outlet port 251 of the drain pipe 250.

[0096] Furthermore, after receiving the operation command for the washing program, the washing machine sends a detection request to the lint filter 20. The lint filter 20 receives the aforementioned detection request and feeds back a detection signal to the washing machine 10. Based on the received detection signal, the washing machine 10 determines whether the water intake 22 of the lint filter 20 is properly connected to the outlet 251 of the drain pipe 250.

[0097] In the above configuration, when the washing equipment 10 receives an operation command, it determines the connection status between the lint filter 20 and the drain pipe 250. If it confirms that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drain pipe 250, it activates the washing program to ensure that the lint filter 20 can be used to achieve an effective drain filtration function during the operation of the washing program. On the other hand, if it determines that the intake port 22 of the lint filter 20 is not connected to the outlet port 251 of the drain pipe 250, it prohibits the operation of the washing program.

[0098] Preferably, the washing equipment 10 issues an alarm signal if it determines that the water intake 22 of the lint filter 20 is not properly connected to the water outlet 251 of the drain pipe 250, prompting the user to check the connection status between the lint filter 20 and the drain pipe 250.

[0099] After the user reconnects the lint filter 20 and the drain pipe 250, the user can operate the washing machine 10 again to issue a command to start the washing program. The washing machine 10 then sends a detection request to the lint filter 20, and the lint filter 20 controls whether to start the washing program based on the detection signal it receives as feedback.

[0100] In this embodiment, a detection element is installed on the lint filter 20, and the aforementioned detection element can detect whether the intake port 22 of the lint filter is properly connected to the outlet end 251 of the drainage pipe 250.

[0101] Specifically, a detection element is installed at the outlet end 251 of the drainage pipe 250, and the detection element is triggered when the distance between the detection element and the detection element is less than a predetermined distance.

[0102] If the lint filter 20 detects that the aforementioned detection element is in a triggered state, it can directly send a signal to the washing machine 10 indicating that the intake port 22 is properly connected to the outlet port 251 of the drainage pipe 250, and the washing machine 10 can start operating the washing program. Alternatively, the lint filter 20 can directly send a detection signal indicating that the aforementioned detection element is in a triggered state, and after receiving the detection signal, that is, after the washing machine 10 detects that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drainage pipe 250, it can start operating the washing program.

[0103] Furthermore, referring to Figures 3 and 4, the detection element in this embodiment includes a magnetically sensitive element, the detected element includes a magnetic component 810, and the magnetically sensitive element can be triggered by an approaching magnetic component 810. When the lint filter 20 detects that the magnetically sensitive element is in a triggered state, or when the washing equipment 10 communicates with the lint filter 20 and detects that the magnetically sensitive element is in a triggered state, the washing program can be started.

[0104] In detail, the magnetic sensing element in this embodiment is a reed switch 820, and a signal output line 823 is connected to the magnetic sensing element to transmit information on whether the reed switch 820 is in a triggered state. The first electrode 821 and the second electrode 822 inside the reed switch 820 do not normally make contact, in which case the reed switch 820 is in a non-triggered state.

[0105] The lint filter 20 is equipped with an outer casing 21, the water intake 22 is provided on the outer casing 21, and the filtration module 600 is installed inside the outer casing 21. The reed switch 820 is mounted on the outer casing 21 in an area close to the water intake 22. As a result, when the water intake 22 is properly connected to the outlet end 251 of the drainage pipe 250, the outlet end 251 comes into contact with the outer casing 21, the magnetic component 810 approaches the reed switch 820, and the magnetic force generated by the magnetic component deforms the first electrode 821 and the second electrode 822, causing them to make contact and conduct electricity. At this time, the reed switch 820 is in a triggered state.

[0106] On the other hand, once the connection between the outlet 251 of the drain pipe 250 and the intake 22 is disconnected, the magnetic component 810 separates from the reed switch 820, and the first electrode 821 and the second electrode 822 return to a non-contact state. At this time, the reed switch 820 is in a non-triggered state, and the washing equipment 10 can determine that the intake 22 of the lint filter 20 is not properly connected to the outlet 251 of the drain pipe 250.

[0107] In a specific embodiment of this product, after the washing machine 10 receives an operation command, the lint filter 20 acquires that the reed switch 820 is in a trigger state that generates a trigger signal. The washing machine 10 then determines that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drain pipe 250, thereby enabling the washing program to be activated. On the other hand, if the lint filter 20 acquires that the reed switch 820 is in a non-trigger state, the washing machine 10 determines that the intake port 22 of the lint filter 20 is not properly connected to the outlet port 251 of the drain pipe 250. In this case, the washing machine 10 prohibits the operation of the washing program.

[0108] It should be explained that in this embodiment, the detection signal that the lint filter 20 feeds back may be whether the reed switch 820 has generated a trigger signal, or it may be a signal that the lint filter 20 has determined on its own based on the conduction / disconnection state of the reed switch 820, indicating whether it is properly connected.

[0109] In this embodiment, the washing equipment 10 and the lint filter 20 can be controlled in conjunction, and the washing equipment 10 can activate the washing program only when it has confirmed that the water intake 22 of the lint filter 20 is properly connected to the water outlet 251 of the drain pipe 250, ensuring that the lint filter 20 can perform an effective filtration function during the operation of the washing program. [Examples]

[0110] As shown in Figures 1 to 4, the difference between this embodiment and Embodiment 2 is that the washing equipment 10 determines whether the water intake 22 of the lint filter 20 is properly connected to the water outlet 251 of the drain pipe 250 while the washing program is running, and controls whether to allow the continuation of the aforementioned washing program.

[0111] Specifically, as shown in Figure 6, if the washing machine 10 detects a signal indicating that the water intake 22 of the lint filter 20 is not properly connected to the water outlet 251 of the drain pipe 250 while the washing machine 10 is running a washing program, it will interrupt the operation of the current washing program.

[0112] On the other hand, if the washing equipment 10 determines that the water intake 22 of the lint filter 20 is properly connected to the water outlet 251 of the drain pipe 250, it maintains the current washing program and continues operation.

[0113] In detail, in this embodiment, the washing machine 10 starts the washing program with the water intake 22 of the lint filter 20 properly connected to the water outlet 251 of the drain pipe 250. Under normal conditions, the reed switch 820 maintains a trigger state in which the first electrode 821 and the second electrode 822 are in contact and conducting during the operation of the washing program. On the other hand, once the water outlet 251 of the drain pipe 250 is removed from the water intake 22 of the lint filter 20, the first electrode 821 and the second electrode 822 are no longer affected by magnetic force and separate. At this time, the lint filter 20 acquires that the reed switch 820 has changed to a non-trigger state and immediately sends a signal to the washing machine 10. The aforementioned signal may be a detection signal indicating that the reed switch 820 has changed to a non-triggered state, or it may be a detection signal that the lint filter 20 has determined, based on the state change of the reed switch 820, to indicate that the intake port 22 of the lint filter 20 is not properly connected to the outlet end 251 of the drainage pipe 250.

[0114] When the washing machine 10 receives the above detection signal, it determines that the water intake 22 of the lint filter 20 is not properly connected to the outlet 251 of the drain pipe 250, and immediately interrupts the washing program to avoid problems such as water leakage and inability to filter that may occur if the washing program continues to run.

[0115] Preferably, the washing machine 10 issues an alarm signal after determining that the intake port 22 of the lint filter 20 is not properly connected to the outlet end 251 of the drain pipe 250, prompting the user to check the connection status of the lint filter 20. After the user reconnects the lint filter 20 to the drain pipe 250, the lint filter 20 acquires that the reed switch 820 has returned to the trigger state and transmits a corresponding detection signal to the washing machine 10. After receiving the detection signal, the washing machine 10 determines that the intake port 22 of the lint filter 20 is now properly connected to the outlet end 251 of the drain pipe 250, and can automatically activate and continue the operation of the interrupted washing program.

[0116] More preferably, since the lint filter 20 is for filtering the wastewater flow of the washing equipment 10, if the washing equipment 10 determines that the intake port 22 of the lint filter 20 is not properly connected to the outlet end 251 of the drain pipe 250 while the washing equipment 10 is in operation, the washing program will be immediately interrupted, i.e., the draining operation will be stopped, if it is the draining stage. If it is not currently the draining stage, an alarm signal will be issued, but the operation will not be interrupted.

[0117] If, after the user receives an alarm signal from the washing machine 10, they immediately complete the reconnection of the lint filter 20 to the drain pipe 250 and send a corresponding detection signal to the washing machine 10 indicating that the lint filter 20 is properly connected, the washing machine 10 can complete its operation without interrupting the washing program.

[0118] On the other hand, if the washing machine 10 has issued an alarm signal and has not received the corresponding detection signal from the lint filter 20 indicating that it is properly connected before the washing program reaches the next draining stage, the washing machine 10 will suspend operation before starting the draining stage and wait for the user to reconnect the lint filter 20 and the drain pipe 250. After the user completes the reconnection operation, the washing machine 10 will receive the corresponding detection signal from the lint filter 20 indicating that it is properly connected and will be able to continue the washing program and start draining.

[0119] In this embodiment, when the washing machine 10 is running a washing program, the lint filter 20 can maintain an effective connection with the drain pipe 25, that is, when the washing machine 10 is running a washing program, the intake port 22 of the lint filter 20 maintains an appropriate connection with the outlet end 251 of the drain pipe 250, and this can be controlled by employing the following two forms.

[0120] In one specific embodiment of this product, the lint filtration device 20 transmits a detection signal to the washing equipment 10 in real time while the washing program is running.

[0121] If the washing machine 10 determines, based on the received detection signal, that the water intake 22 of the lint filter 20 is properly connected to the water outlet 251 of the drain pipe 250, it will maintain the current washing program and continue operation. On the other hand, if the washing machine 10 determines, based on the received detection signal, that the water intake 22 of the lint filter 20 is not properly connected to the water outlet 251 of the drain pipe 250, it will control the machine to interrupt the operation of the washing program.

[0122] In another specific embodiment of this design, the lint filter 20 does not send a detection signal to the washing machine 10 if it has detected that the intake port 22 of the lint filter 20 maintains a proper connection with the outlet port 251 of the drain pipe 250, i.e., that the reed switch 820 remains in the triggered state. Only when a connection abnormality occurs and the lint filter 20 has detected that the reed switch 820 has changed to a non-triggered state does it send a corresponding detection signal to the washing machine 10 indicating that the connection is not properly maintained.

[0123] If the washing machine 10 does not receive the corresponding detection signal indicating that it is not properly connected, the lint filter 20 determines that the intake 22 is properly connected to the outlet 251 of the drain pipe 250, and therefore continues operation while maintaining the current washing program. Once the washing machine receives the aforementioned detection signal, it determines that the intake 22 of the lint filter 20 is not properly connected to the outlet 251 of the drain pipe 250, and controls the machine to interrupt the operation of the washing program.

[0124] In this embodiment, the washing equipment 10 can acquire the connection status between the lint filter 20 and the drain pipe 250 during operation. If a connection abnormality occurs, such as the drain pipe 250 becoming loose and detaching from the lint filter 20, the washing program can be immediately interrupted, effectively preventing problems such as water leakage and inability to filter that may occur if the washing program continues to run.

[0125] In this embodiment, it should be understood that the control method applied during the operation of the washing program can also be applied in combination with the control method provided in Embodiment 2. That is, after the washing machine 10 receives an operation command, it controls whether to start the operation of the washing program based on the signal fed back by the lint filter 20, and after the operation of the washing program has started, it controls whether to interrupt the washing program based on the signal transmitted by the lint filter 20. In this way, it is possible to ensure that the lint filter 20 performs an effective filtering function both before and during the operation of the washing program. [Examples]

[0126] As shown in Figures 1 and 4, the difference between this embodiment and Embodiment 1 is that the aforementioned detection module determines whether the water intake 22 is properly connected to the external connection pipeline, i.e., the drain pipeline 250 of the washing equipment 10, by detecting the water intake information of the filtration module 600.

[0127] Specifically, if water is entering the filtration module 600 when the washing equipment 10 drains to the outside, it indicates that the drain pipe 250 can effectively send the drain water flow from the intake 22 of the lint filter 20, and thus it can be confirmed that the intake 22 and the outlet 251 of the drain pipe 250 are properly connected at this point. Conversely, if no water is entering the filtration module 600, it indicates that the drain water flow has been discharged along the drain pipe 250 and has not entered the lint filter 20, meaning that at this point, there is a high probability that the intake 22 and the outlet 251 of the drain pipe 250 are abnormally connected or not properly connected.

[0128] Similar to Embodiment 1 described above, the lint filter 20 may self-determine whether the water intake 22 is properly connected to the outlet 251 of the drainage pipe 250 based on the water intake information detected by the detection module, or it may transmit the detected water intake information to the washing equipment 10 or a cloud server, and the washing equipment 10 or the cloud server may determine, based on the aforementioned water intake information, whether the water intake 22 of the lint filter 20 is properly connected to the outlet 251 of the drainage pipe 250.

[0129] In one specific embodiment of this product, the water intake information detected by the aforementioned detection module is the water flow rate information flowing through the filtration module 600. Specifically, the aforementioned detection module is equipped with a flow meter capable of detecting the water flow rate flowing through the filtration module 600. When the aforementioned flow meter detects a water flow passing through the filtration module 600, that is, when the detected water flow rate is not zero, it is determined at this point that the water intake 22 is properly connected to the outlet end 251 of the drainage pipe 250 of the washing equipment 10.

[0130] In detail, the aforementioned flow meter may be installed at the water intake 22 location, or it may be installed in the flow path connecting the water intake 22 and the filtration module 600, thereby detecting the flow rate of water flowing through the filtration module 600.

[0131] In another specific embodiment of this model, the water intake information detected by the aforementioned detection module is the water level information within the filtration module 600. Specifically, the aforementioned detection module is equipped with a sensor for detecting the water level information within the filtration module 600. When the aforementioned sensor detects that there is water inside the filtration module 600, that is, when the detected water level is not zero, the lint filtration device 20 can determine that the water intake 22 is properly connected to the outlet end 251 of the drainage pipe 250 of the washing equipment 10.

[0132] In detail, the filtration module 600 is equipped with a filtration cavity 610 for receiving water to be filtered, and the aforementioned sensor is installed inside the filtration cavity 610, thereby enabling detection of the water level within the filtration cavity 610. Since the wastewater flow can only be discharged after it has entered the filtration module 600 and been filtered, the flow rate of water entering the filtration module 600 is generally greater than the flow rate of water discharged from the filtration module 600 after filtration. Therefore, after the wastewater from the washing equipment 10 enters the filtration module 600, a certain amount remains within the filtration module 600. This makes it possible to accurately determine whether water is entering the filtration module 600 by detecting whether there is water inside the filtration module 600.

[0133] In the above configuration, the aforementioned sensor may be any sensor capable of realizing a water level detection function, such as a water level sensor or an infrared sensor.

[0134] In this embodiment, the lint filter 20 uses a detection module to detect whether water is entering the filter module 600, thereby determining the connection status between the intake port 22 of the lint filter and the outlet end 251 of the drain pipe 250. The above detection and determination logic can only be implemented when the washing equipment 10 needs to drain water, and since the lint filter 20 is specifically for implementing the drainage filtration function of the washing equipment 10, it does not affect other operating stages of the washing equipment 10 other than drainage. In this way, the washing equipment 10 acquires the connection status between the lint filter 20 and the drain pipe 250 only during the drainage stage, thereby avoiding the problem that if the washing equipment 10 does not drain water, operation will be interrupted due to an abnormal connection between the lint filter 20 and the drain pipe 250, affecting the efficiency of the washing operation. [Examples]

[0135] This embodiment provides a method for controlling a washing system.

[0136] As shown in Figure 1, the laundry system according to this embodiment comprises a laundry machine 10 and a lint filter 20 installed outside the laundry machine 10. The laundry machine 10 is equipped with a drainage pipe 250 for draining water to the outside, and the outlet end 251 of the drainage pipe 250 is connected to the intake port 22 of the lint filter 20. It should be noted that the aforementioned laundry machine 10 may be a home appliance capable of performing clothing washing functions, such as a washing machine, a washer-dryer, or a garment care machine.

[0137] Specifically, as shown in Figures 1 and 4, the lint filter device 20 of this embodiment is equipped with a filtration module 600, and the water intake 22 of the lint filter device 20 is in communication with the filtration module 600. The wastewater flow from the washing equipment 10 is sent to the lint filter device 20 via the drainage pipe 250, and the filtration module 600 receives the water to be filtered and performs filtration.

[0138] Furthermore, in this embodiment, the washing equipment 10 and the lint filter 20 are connected via communication, enabling coordinated control of both. This allows the washing equipment 10 to acquire the connection status between the lint filter 20 and the drain pipe 250. In this way, the washing equipment 10 can control its operation based on the above connection status, ensuring that the lint filter 20 can perform its filtration function effectively.

[0139] Specifically, as shown in Figures 1 and 4, the control method of this embodiment is applied to the washing system provided in Embodiment 4 described above. The aforementioned control method is The washing machine 10 operates the washing program, The system includes determining whether the intake port 22 of the lint filter 20 is properly connected to the outlet end 251 of the drainage pipe 250 once a preset operating stage is reached.

[0140] In the above configuration, the washing equipment 10 does not need to maintain real-time communication with the washing equipment 10 because the lint filter 20 does not need to maintain real-time communication with the washing equipment 10 in order to determine whether the intake port 22 of the lint filter 20 is properly connected to the outlet end 251 of the drain pipe 250 at a specific operating stage in the washing program.

[0141] Furthermore, the washing equipment 10 in this embodiment can control whether to continue operation in the current operating stage based on whether the lint filter 20 is effectively connected to the drain pipe 250, thereby ensuring that the lint filter 20 can effectively perform its filtering function.

[0142] The aforementioned "effectively connected" means that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drainage pipe 250, that all of the wastewater flow in the drainage pipe 250 can enter the lint filter 20 from the intake port 22, and that no water leakage occurs at the connection point.

[0143] In a further embodiment of this example, the aforementioned preset operating stages include the drainage stage of the washing program. As shown in Figure 7, in the control method of this example, the washing equipment 10 operates the washing program until it reaches the aforementioned drainage stage, and if it determines that the intake port 22 of the lint filter 20 is not properly connected to the outlet port 251 of the drainage pipe 250, it interrupts drainage to the outside. On the other hand, if the washing equipment 10 determines that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drainage pipe 250, it maintains a state of continuing drainage to the outside.

[0144] In this embodiment, the lint filter 20 is connected to the drainage pipe 250 of the washing equipment 10. The drainage pipe 250 is designed to provide a filtration effect on the wastewater flow. During the drainage phase of the washing program, the washing equipment 10 determines the connection status between the intake port 22 of the lint filter 20 and the outlet port 251 of the drainage pipe 250. If it determines that there is an abnormality in the connection, it interrupts drainage. This effectively prevents the problem where, if the intake port 22 is not properly connected to the outlet port 251 of the drainage pipe 250, the wastewater flow leaks out from the intake port 22 of the lint filter 20 and enters the lint filter 20, preventing filtration.

[0145] Furthermore, when the washing equipment 10 of this embodiment runs the washing program and reaches the drainage stage, it acquires operating status information of the lint filter 20 and determines whether the intake port 22 of the lint filter 20 is properly connected to the outlet end 251 of the drainage pipe 250 based on the aforementioned operating status information.

[0146] Specifically, when the washing machine 10 operates the washing program and reaches a preset operating stage, namely the aforementioned drainage stage, it sends a detection request to the lint filter 20. Upon receiving the aforementioned detection request, the lint filter 20 sends current operating status information to the washing machine 10.

[0147] The above method makes it possible to determine whether the water intake 22 of the lint filter 20 is properly connected to the water outlet 251 of the drain pipe 250 during a specific operating stage of the washing equipment 10, that is, the drainage stage of the washing equipment 10 in this embodiment.

[0148] In a further embodiment of this design, the operating status information of the lint filter 20 includes the water intake information of the lint filter 20, which is also the water intake information of the filter module 600 detected by the detection module. The washing equipment 10 can directly receive the aforementioned water intake information and determine whether the water intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drain pipe 250.

[0149] Specifically, if the washing equipment 10 determines, based on the aforementioned water intake information, that the wastewater flow in the drainage pipe 250 is entering the lint filter 20, it determines that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drainage pipe 250 and controls the system to maintain a state of continuous drainage to the outside. Conversely, if the washing equipment 10 detects, based on the aforementioned water intake information, that the wastewater flow in the drainage pipe 250 is not entering the lint filter 20, it determines that the intake port 22 of the lint filter 20 is not properly connected to the outlet port 251 of the drainage pipe 250 and controls the system to interrupt drainage.

[0150] In this embodiment, when the washing machine 10 runs the washing program and reaches the drainage stage, it drains water to the outside and simultaneously acquires water intake information from the filtration module 600 detected by the aforementioned detection module. After acquiring the aforementioned water intake information, the washing machine 10 further determines whether the water intake port 22 of the lint filter 20 is properly connected to the outlet end 251 of the drainage pipe 250, and controls whether to interrupt drainage based on the determination result.

[0151] In a specific embodiment of this product, the aforementioned water intake information includes water flow rate information flowing through the lint filter 20 in order to determine whether the wastewater flow is entering the lint filter 20 based on the aforementioned water intake information. During the drainage stage of the washing program, if the washing equipment 10 acquires the aforementioned water flow rate information and determines that there is a water flow passing through the lint filter 20, it determines that the water intake 22 of the lint filter 20 is properly connected to the outlet 251 of the drain pipe 250.

[0152] In detail, a flow meter is installed inside the lint filter 20 to detect the flow rate of water flowing through the lint filter 20. The aforementioned flow meter may be installed at the water intake 22 location, or it may be installed in the flow path connecting the water intake 22 and the filtration module 600.

[0153] When the washing machine 10 runs the washing program and reaches the drainage stage, it drains the water to the outside and simultaneously acquires the detection result from the flow meter. As long as the flow meter detects a water flow passing through it, that is, as long as the detected water flow rate is not zero, it can be determined that the drained water flow is entering the lint filter 20, and it can be determined that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drain pipe 250. At this point, the washing machine 10 can maintain a state where it continues to drain water to the outside.

[0154] Conversely, if the washing equipment 10 obtains the flow meter's detection result and the detected water flow rate is zero, it indicates that the wastewater flow is not entering the lint filter 20, and it is determined that the intake port 22 of the lint filter 20 is not properly connected to the outlet port 251 of the drain pipe 250. In such a case, the washing equipment 10 interrupts drainage to the outside and avoids problems such as water leakage or inability to filter by continuing drainage.

[0155] Furthermore, in this embodiment, when the washing machine 10 runs the washing program and reaches the drainage stage, it starts the drainage operation to the outside. After starting the drainage operation to the outside, if the washing machine 10 acquires water intake information indicating that the drained water flow has entered the lint filter 20 within a predetermined time, it maintains the state of continuing drainage to the outside. After starting the drainage operation to the outside and reaching a predetermined time, if the washing machine 10 does not continuously acquire water intake information indicating that the drained water flow has entered the lint filter 20, it interrupts the drainage operation to the outside.

[0156] In detail, when the washing machine 10 runs the washing program and reaches the draining stage, it starts the draining operation to the outside and simultaneously starts timing. If the washing machine 10 receives a signal indicating that the water flow rate detected by the flow meter is not zero before the preset time is reached, it continues to drain to the outside. On the other hand, if the received flow meter detection result is always zero when the timing reaches the preset time, it interrupts the draining operation to the outside.

[0157] In the above configuration, since the drainage pipe 250 has a fixed length, there is a fixed time interval between the time the washing equipment 10 activates the drainage pump 400 to start draining and the time the drainage water flow enters the lint filter 20 and passes through the aforementioned flow rate meter. If the flow meter still does not detect the passage of water flow even after a preset time has been reached since the start of drainage, it indicates that there is a problem with the connection between the lint filter 20 and the drainage pipe 250, and drainage must be stopped. By setting the aforementioned preset time, the washing equipment 10 avoids the misjudgment that the intake port 22 of the lint filter 20 is not properly connected to the outlet port 251 of the drainage pipe 250, because the flow meter detects zero water flow when the drainage water flow is not flowing to the flow meter's position.

[0158] In a preferred embodiment of this model, the washing machine 10 interrupts drainage and simultaneously issues an alarm to prompt the user to check the connection between the lint filter 20 and the drain pipe 250. After reconnecting the lint filter 10 and the drain pipe 250, the user can issue a control command to continue operating the washing program. The washing machine 10 continues draining to the outside and simultaneously uses a flow meter to detect whether there is a water flow passing through, thereby allowing it to re-determine whether the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drain pipe 250.

[0159] In this embodiment, when the washing program reaches the drainage stage, the washing equipment 10 works in conjunction with the lint filter 20 to determine whether the lint filter 20 is effectively connected to the drain pipe 250. This allows for immediate interruption of drainage if a connection problem occurs, effectively preventing problems such as water leakage and inability to achieve effective filtration that may occur if the connection is not properly established. The determination of the connection status between the lint filter 20 and the drain pipe 250 is achieved by detecting the water flow rate in the lint filter 20, which does not require a complex detection structure and allows for accurate determination results. [Examples]

[0160] As shown in Figures 1, 4, and 7, the difference between this embodiment and Embodiment 5 is that the aforementioned water intake information includes the water level information inside the aforementioned lint filter 20.

[0161] Specifically, during the drainage stage of the washing program, the washing equipment 10 acquires the aforementioned water level information and, if it determines that there is water inside the lint filter 20, it determines that the water intake 22 of the lint filter 20 is properly connected to the outlet 251 of the drainage pipe 250.

[0162] In this embodiment, the amount of wastewater entering the lint filter 20 flows along the internal flow path of the lint filter 20 into the filtration module 600, where it is filtered before being discharged. Since the water flow is filtered inside the filtration module 600, the flow rate of water entering the filtration module 600 is generally greater than the flow rate of filtered water discharged from the filtration module 600. Therefore, a certain amount of wastewater from the washing equipment 10 remains inside the filtration module 600 after entering it.

[0163] The water level information inside the lint filter 20 described above specifically refers to the water level information inside the filtration module 600. By detecting the water level inside the filtration module 600 and determining whether or not there is water inside the filtration module 600, it is possible to accurately determine whether or not water flow is entering the lint filter 20.

[0164] In detail, the filtration module 600 in this embodiment includes a filtration cavity 610 for receiving the water to be filtered. A sensor for detecting the water level is installed inside the filtration cavity 610, allowing real-time acquisition of water level information within the filtration module 600. It should be understood that the aforementioned sensor may be any sensor capable of realizing a water level detection function, such as a water level sensor or an infrared sensor.

[0165] When the washing machine 10 runs the washing program and reaches the draining stage, it starts the draining operation to the outside and simultaneously acquires the detection results of the aforementioned sensor. As long as the aforementioned sensor detects that there is water inside the filtration module 600, that is, if the detected water level is not zero, it can be determined that the drain water flow is entering the lint filter 20, and it can be determined that the intake port 22 of the lint filter 20 is properly connected to the outlet port 251 of the drain pipe 250. At this time, the washing machine 10 can maintain the state of continuing to drain to the outside.

[0166] Conversely, if the washing equipment 10 obtains the sensor's detection result and the detected water level is zero, it indicates that the wastewater flow is not entering the lint filter 20, and it is determined that the intake port 22 of the lint filter 20 is not properly connected to the outlet port 251 of the drain pipe 250. In such a case, the washing equipment 10 interrupts drainage to the outside and avoids problems such as water leakage or inability to filter by continuing drainage.

[0167] Similar to Embodiment 5 described above, in this embodiment, when the washing machine 10 runs the washing program and reaches the draining stage, it starts the draining operation to the outside and simultaneously starts timing. After starting draining to the outside, if the washing machine 10 receives a signal within a preset time indicating that the water level detected by the sensor is not zero, it maintains the state of continuing to drain to the outside. On the other hand, if the water level detected by the received sensor is always zero after starting the draining operation to the outside and reaching a preset time, the draining operation to the outside is interrupted.

[0168] In this embodiment, the washing equipment 10 can accurately determine the connection status between the lint filter 20 and the drain pipe 250 by acquiring the water level in the filtration module 600, thereby controlling whether or not it can maintain a state of continuous drainage. [Examples]

[0169] As shown in Figures 1 and 4, this embodiment further limits the above embodiment, and the aforementioned lint filtration device 20 further comprises a collection module 500. The filtration module 600 has a self-cleaning capability, and can self-clean the filtration foreign matter accumulated during filtration, discharge the cleaned filtration foreign matter with the water flow, and finally send it into the collection module 500 for collection.

[0170] Specifically, the filtration module 600 has a wastewater outlet 6103 for discharging wastewater containing filtered foreign matter. The collection module 500 communicates with the wastewater outlet 6103 for receiving the wastewater discharged from the filtration module 600.

[0171] In this embodiment, the filtration module 600 has a certain self-cleaning capability, allowing the accumulated filtration foreign matter during the filtration process to flow into the collection module 500, thus avoiding the impact of a large accumulation of filtration foreign matter on filtration efficiency. The lint filtration device 20 avoids the problem of microplastics in the filtration foreign matter entering the ecological cycle by receiving the wastewater discharged from the filtration module 600 using the collection module 500, rather than directly discharging it to the outside.

[0172] In a specific embodiment of this model, in order to achieve self-cleaning of the filtration module 600, the specific structure of the filtration module 600 is as follows: A filtration cavity 610 is provided with an inlet 6101, a filtered water outlet 6102, and a wastewater outlet 6103, A filtration mechanism 620 having a water outlet joint 621 that is rotatably installed inside the filtration cavity 610 and rotatably sealed to the filtration water outlet 6102, It comprises a drive mechanism 660 connected to a filtration mechanism 620 for rotationally driving the filtration mechanism 620 within the filtration cavity 610.

[0173] Of these, the inlet 6101 on the filtration cavity 610 communicates with the intake 22, and the water to be filtered that enters from the intake 22 enters the filtration cavity 610 through the inlet 6101. The filtration mechanism 620 divides the inside of the filtration cavity 610 into an outer cavity and an inner cavity, with the inlet 6101 communicating with the aforementioned outer cavity and the filtered water outlet 6102 communicating with the inner cavity. The water to be filtered enters the outer cavity from the inlet 6101, passes through the filtration mechanism 620, and enters the inner cavity to achieve filtration. Filtered foreign matter accompanying the water adheres to the outer wall of the filtration mechanism 620, and the water from which the filtered foreign matter has been removed can flow out from the filtered water outlet 6102 via the outlet joint 621. The filtered water outlet 6102 is connected to the water outlet 23 on the outer casing 21, thereby allowing filtered water to be discharged through the water outlet 23.

[0174] In detail, the filtration mechanism 620 comprises a filter mesh support and a filter mesh covering the aforementioned filter mesh support. One end of the aforementioned filter mesh support extends to the filtered water outlet 6102 to form a water outlet joint 621.

[0175] When it is necessary to clean the filtration debris inside the filtration module 600, the drive mechanism 600 rotates the filtration mechanism 620, agitating the water flow in the filtration cavity 610. This allows the filtration debris adhering to the outer wall of the filtration mechanism 620 to be detached by the combined action of centrifugal force and the vigorous vibration of the water flow, and then dissolved into the water in the filtration cavity 610. The wastewater containing the filtration debris is discharged along with the water flow from the wastewater outlet 6103 on the filtration cavity 610. The wastewater outlet 6103 is connected to the wastewater discharge pipe 240, which sends the wastewater into the collection module 500.

[0176] Furthermore, a wastewater discharge control valve 241 is installed on the wastewater discharge pipe 240 to control the opening and closing of the wastewater discharge pipe 240. When the washing equipment 10 drains to the lint filtration device 20 for filtration, the wastewater discharge control valve 241 closes, blocking the wastewater discharge pipe 240. In this way, the filtration module 600 does not drain wastewater to the outside from the wastewater outlet 6103, thereby ensuring that all water that enters the filtration cavity 610 from the water inlet 6101 is filtered by the filtration mechanism 620 and can then be discharged from the filtered water outlet 6102.

[0177] The wastewater discharge control valve 241 is opened and the wastewater discharge pipeline 240 is opened only when the filtration module 600 needs to discharge wastewater. At this time, the filtration module 600 can discharge wastewater from the wastewater outlet 6103 to the collection module 500 and remove any filtered foreign matter accumulated in the filtration cavity 610.

[0178] In a further embodiment of this design, the collection module 500 is removably mounted within the casing 21 of the lint filter 20, allowing the user to periodically clean the collection module 500, and in particular, to clean any filtration debris that has accumulated inside the collection module 500 after receiving wastewater.

[0179] Specifically, the collection module 500 comprises a case 510 and a lint collection assembly 570 installed inside the case 510. The case 510 has a collection chamber inside, and the lint collection assembly 570 is installed inside the collection chamber, surrounding it to form a collection space for receiving wastewater. The outlet end of the wastewater discharge pipe 240 communicates with the collection space, and wastewater containing filtered foreign matter enters the collection space, is filtered by the lint collection assembly 570, and then flows into the collection chamber outside the collection space, where the filtered foreign matter is collected.

[0180] In detail, the lint collection assembly 570 may form the aforementioned collection space by directly surrounding it with a filter mesh, or it may form the aforementioned collection space by covering a support with a filter mesh.

[0181] In the above configuration, the collection module 500 filters the wastewater received using the lint collection assembly 570, thereby separating the filtered foreign matter from the water. In this way, it is possible to facilitate the user to directly process the collected filtered foreign matter and avoid situations where the filtered foreign matter is mixed in with the water and cannot be effectively processed.

[0182] Furthermore, the case 510 is retractably mounted on the outer casing 21 and has an opening on its upper side. The lint collection assembly 570 is removably mounted inside the case 510. If the collection module 500, in particular the lint collection assembly 570 inside the collection module 500, needs to be cleaned, the user can remove the lint collection assembly 570 from inside the case 510 through the opening on the upper side of the case 510 when pulling the case 510 out of the outer casing 21, and clean it. At this time, it is not necessary to completely pull out the collection module 510, making handling even more convenient.

[0183] Preferably, a drain port (not shown) is installed on the case 510, so that the wastewater filtered by the lint collection assembly 570 can enter the collection chamber and be quickly discharged from the aforementioned drain port without remaining in the collection chamber, thus avoiding the problem of the collection module 500 overflowing if the amount of wastewater discharged by the filtration module 600 is excessive. Also, since there is no water inside the case 510, when the user manually cleans the collection module 500, they do not need to pull out the case 510 and turn it over to remove the water inside, thus simplifying the manual cleaning of the collection module 500.

[0184] More preferably, the aforementioned drain port is connected to the outside of the lint filter 20 via an additional pipeline, thereby allowing the wastewater that does not contain filtered foreign matter to be discharged after filtration. Alternatively, the aforementioned drain port can be connected to the flow path between the filtered water outlet 6102 and the outlet 23 via a pipeline, thereby allowing the filtered wastewater to be discharged from the outlet 23 together with the filtered water discharged from the filter module 600 and flow into the floor drain port along the discharge pipe 24.

[0185] In a preferred embodiment of this design, a filtration control valve 231 is further installed between the filtered water outlet 6102 and the water outlet 23, and the opening and closing of the filtration control valve 231 can control the opening and closing of the connection between the filtered water outlet 6102 and the water outlet 23.

[0186] When the filtration module 600 filters the wastewater from the washing equipment 10 that enters it, the filtration control valve 231 remains open, opening the connection between the filtered water outlet 6102 and the outlet 23. As a result, the filtered water is discharged from the filtration cavity 610 via the filtered water outlet 6102 and further discharged from the lint filtration device 20 via the outlet 23. On the other hand, when the filtration module 600 discharges the cleaning wastewater, the filtration control valve 231 is controlled to close, blocking the connection between the filtered water outlet 6102 and the outlet 23. In this way, the water in the filtration cavity 610 is not discharged from the filtered water outlet 6102, making it easier for the water flow in the filtration cavity 610 to flow into the collection module 500 with more filtered foreign matter.

[0187] In a further embodiment of this design, the filter mesh within the filtration module 600 is selected to have a mesh size of 20 to 500 in order to enable the filtration module 600 to filter and remove microplastics, particularly plastic fibers with a length exceeding 50 μm and a diameter of 10 to 1000 μm. Furthermore, to ensure that the collection module 500 can collect as much microplastic as possible from the wastewater, and that the microplastics filtered by the filtration module 600 do not pass through the lint collection assembly 570 within the collection module 500, the pore size on the filter mesh within the lint collection assembly 570 is at least less than or equal to the pore size of the filter mesh within the filtration module 600. That is, the mesh count of the filter mesh within the lint collection assembly 570 is 20 to 500 mesh or more, which is the same as the mesh count of the filter mesh within the filtration module 600.

[0188] In this embodiment, extensive testing and trials were conducted beforehand on different types of clothing and different washing programs. The results showed that by setting the mesh count of the filter screen in the lint collection assembly 570 and the mesh count of the filter screen in the filtration module 600 within the above range, when the lint filtration device 20 is externally connected to the drainage pipe 250 of the washing equipment 10, plastic fibers of the above dimensions can be filtered from the wastewater of the washing equipment 10. Ultimately, microplastic particles accounting for more than 80% of the total content in the water can be collected in the collection module 500. This significantly reduces the microplastic content in the wastewater flow of the washing equipment 10, thus meeting the standards for direct release.

[0189] In this embodiment, the filtration module 600 of the lint filter 20 has a self-cleaning function, which avoids the problem of the filtration module 600 becoming clogged and unable to perform filtration, and also eliminates the need for the user to manually clean the filtration module 600. By installing the collection module 500, the cleaning wastewater discharged from the filtration module 600 can be received, and filtered foreign matter in the wastewater can be separated from the water, preventing the wastewater from being directly discharged along with microplastics in the filtered foreign matter, and ensuring that the microplastic content in the final discharged water stream meets the standards for direct discharge.

The present invention has already been disclosed as described above by preferred embodiments, but this is not intended to limit the present invention.
