Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and more specifically, relates to a control method for a washing equipment and the washing equipment. Background Art

[0002] Washing equipment for cleaning clothes, such as a washing machine, during the process of washing clothes, due to the friction between clothes and between clothes and the washing machine itself, lint will fall off from the clothes and mix into the washing water. If the lint in the washing water cannot be removed, it is very likely to adhere to the surface of the clothes after the laundry is completed, affecting the washing effect of the clothes. For this reason, a filter for filtering lint is installed on existing washing machines, and the washing water continuously passes through the filter during the laundry process to remove the lint from the washing water.

[0003] However, the filtered lint will continuously accumulate in the filter. When the lint collection reaches a certain amount, it will affect the realization of the filtering function. And the filter is generally installed inside the washing machine, and users cannot directly observe the lint collection situation therein, and can only clean it regularly. But if the amount of lint falling off from the clothes washed by the user within a period of time is large, or the user forgets to clean the filter for a long time, the filter may become clogged. At this time, if the user uses the washing machine to wash clothes, since the filter cannot perform the filtering function, it will affect the washing effect of the clothes.

[0004] In recent years, the concept of microplastics has been proposed in the environmental protection field and has gradually received increasing attention. Research has found that an important source of microplastics is the wastewater discharged from household washing machines. This is because with the popularization of chemical fiber fabrics, the clothing fibers shed during the laundry process are discharged with the drainage water flow of the washing machine and become microplastics mixed into the natural water environment. Microplastics directly enter the ecological cycle with the drainage water flow and will eventually accumulate in the human body through the natural biological chain, which may have an impact on human health. For this reason, relevant standards have been formulated for the content of microplastics in the drainage of washing machines in some regions. And once the washing machine runs for laundry when the filter cannot be used, the lint shed from the clothes may be directly discharged with the drainage water flow of the washing machine, thereby causing a large amount of microplastics in the drainage of the washing machine and not meeting the emission standards.

[0005] In the prior art, there is no solution that can detect the lint collection situation in the filter. Moreover, since the water flow entering the filter carries lint, that is, a complex water body of solid-liquid mixture, if a conventional fault detection device is directly applied, the risk of inaccurate detection is very high. And generally, as long as a fault detection device is triggered, it will issue an alarm. If the detection accuracy is low, it is very easy to trigger false alarms and affect the user experience.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a control method and washing device for a washing device, which improves the accuracy of the alarm for excessive lint collection in a lint collection device through multi-point detection.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A control method for a washing device, the washing device comprising a lint collecting device and a detection device, the lint collecting device being used to filter and collect lint in water; the detection device being triggered when the filtering capacity of the lint collecting device is reduced;

[0010] After the washing program of the washing device is finished, in response to the number of times the detection device is triggered during this operation, it controls whether to issue an alarm message for cleaning the lint collecting device.

[0011] Further, triggering the detection device when the filtering capacity of the lint collecting device is reduced includes:

[0012] The liquid level in the wire scrap collection device rises, triggering the detection end of the detection device to contact and conduct with water;

[0013] Alternatively, the pressure in the lint collecting device increases, triggering the detection device to operate due to the increase in pressure.

[0014] Furthermore, the washing equipment records the number of times the detection device is triggered within a preset stage during this operation, and if the number is greater than or equal to the preset number, an alarm message for cleaning the lint collecting device is issued.

[0015] Furthermore, during the running of the washing program, a lint discharge operation of draining water to the lint collection device is performed at least once; and the preset stage is staggered with the execution of the lint discharge operation.

[0016] Furthermore, when the detection device is triggered a number of times greater than or equal to a preset number of times within a preset stage, the washing device issues the alarm message during a standby stage before starting a washing program next time.

[0017] Furthermore, the washing device also obtains the number of times the washing program has been run; when the number of times the washing program has been run is greater than or equal to a first threshold, the washing device controls whether to issue an alarm signal in response to the number of times the detection device is triggered during this operation.

[0018] Furthermore, after the washing device issues the alarm message, the number of operations is controlled to be reset to zero.

[0019] Further, if the number of times of operation reaches the second threshold, the washing device sends an alarm message for cleaning the lint collection device during the standby stage before starting the washing program next time, and controls the number of times of operation to be cleared; the second threshold is greater than the first threshold.

[0020] Further, after the washing device sends the alarm message, it judges whether the lint collection device has been cleaned;

[0021] If it is judged that the lint collection device has not been cleaned, in response to the program start instruction received for the first time after the alarm message is sent, the washing program is started; after the operation of this washing program ends, it will no longer respond to the program start instruction received again.

[0022] A washing device executes the control method of the washing device described above.

[0023] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0024] In the present invention, the washing device responds to the number of times the detection device is triggered, and then controls whether to send an alarm message to remind the user to clean the lint collection device, rather than alarming immediately when the detection device is triggered, effectively avoiding the problem of false alarms easily occurring in single detection and improving the user experience.

[0025] In the present invention, the washing device adopts a combination of two detection indexes, namely the number of times the washing program has been run and whether the detection device is triggered multiple times, to control whether to send an alarm message, further reducing the risk of false alarms caused by the low detection accuracy of the detection device itself.

[0026] In the present invention, after the washing device sends the alarm message, it can still run the washing program once more, avoiding the problem that the user still needs to clean the lint collection device first before washing when eager to use the washing device, and improving the user experience.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0038] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] An embodiment of the present invention provides a control method for a washing device and a washing device that executes the control method. The washing device may be a washing machine, a washer-dryer, a care machine, or other washing devices with a clothing cleaning function.

[0040] Specifically, as Figures 1 to 3 shown, the washing device of this embodiment includes a lint collection device 500, which can filter the water flow carrying lint through the lint collection device 500, separate the lint from the water, and collect it. The filtered lint contains microplastics. The lint is collected inside the lint collection device 500, and the water without lint after filtration can be directly discharged from the washing device, without causing the problem of direct discharge of microplastics.

[0041] More specifically, the washing device of this embodiment is provided with a filtration system including a lint filtration device 600 and a lint collection device 500. Among them, the lint filtration device 600 is communicated with the water storage cylinder 100, and the water in the water storage cylinder 100 can be transported to the lint filtration device 600 for filtration under the driving action of the water pump 400. The lint filtration device 600 also has a self-cleaning function, and the lint collected in the lint filtration device 600 during the filtration process can be discharged with the water flow. The lint collection device 500 is communicated with the lint filtration device 600, and the lint water discharged after the self-cleaning of the lint filtration device 600 is discharged into the lint collection device 500, and the lint collection device 500 can filter the lint water and collect the lint containing microplastics from the lint water.

[0042] It should be noted that in the embodiment of the present invention, the "lint water" refers to the water flow discharged from the lint filtration device 600 and carrying a large amount of lint.

[0043] As a specific solution, the lint filtration device 600 has a water inlet 6101, a filtered water outlet 6102, and a lint discharge outlet 6103. Among them, the water inlet 6101 is communicated with the water storage cylinder 100 and is used to receive the water to be filtered. The filtered water is discharged from the filtered water outlet 6102, and the lint discharge outlet 6103 is used to discharge the lint water carrying lint after self-cleaning. The lint discharge outlet 6103 is communicated with the water inlet 511 of the lint collection device 500 through a lint discharge waterway 240, and the discharged lint water can enter the lint collection device 500 along the lint discharge waterway 240.

[0044] In a more specific embodiment, the lint filtering device 600 includes a filtering housing and a rotatable filtering cylinder disposed inside the filtering housing. The water to be filtered enters the filtering housing through the water inlet 6101. Lint and the like are blocked by the filtering cylinder and adhere to the outer wall of the filtering cylinder. The filtered water enters the interior of the filtering cylinder and is finally discharged through the filtered water outlet 6102. The lint filtering device 600 rotates the filtering cylinder to shake off the lint adhering to the outer wall of the filtering cylinder, thereby realizing self-cleaning of the lint filtering device 600.

[0045] Furthermore, the lint collecting device 500 is disposed at a position lower than the height of the lint discharge outlet 6103 of the lint filtering device 600. In this way, after the lint water in the lint filtering device 600 is discharged from the lint discharge outlet 6103, it can be discharged into the lint collecting device 500 under the action of gravity without the need for additional driving force. There is no need to separately provide a driving device for the lint discharge operation of discharging the lint water of the lint filtering device 600 inside the washing device, and the function of automatically discharging the lint water of the lint filtering device 600 can be realized.

[0046] Preferably, the lint discharge outlet 6103 is disposed at the bottom of the lint filtering device 600, which is beneficial to fully discharge the lint and water in the lint filtering device 600 and prevent the problem of residual accumulated water in the lint filtering device 600.

[0047] Even further, a on-off valve 241 is also disposed on the lint discharge water path 240. When the lint filtering device 600 receives the water in the water holding cylinder 100 for filtering, the on-off valve 241 is closed to cut off the lint discharge water path 240, ensuring that the water entering the lint filtering device 600 can be discharged through the filtered water outlet 6102 after being filtered, rather than being directly discharged from the lint discharge outlet 6103 under the action of gravity and flowing into the lint collecting device 500 along the lint discharge water path 240. Only when the lint filtering device 600 needs to discharge the collected lint therein, the on-off valve 241 is opened to conduct the lint discharge water path 240, so that the lint in the lint filtering device 600 is discharged along with the water flow and flows into the lint collecting device 500 along the lint discharge water path 240.

[0048] In this embodiment, the filtered water outlet 6102 of the lint filtering device 600 is respectively communicated with the return water path 230 and the drain pipe path 250 through a switching valve 270. Among them, the water outlet end of the return water path 230 is communicated with the water holding cylinder 100 for re-introducing the filtered water back into the water holding cylinder 100. The drain pipe path 250 extends outside the housing 10 of the washing device for discharging the filtered water out of the washing device.

[0049] Specifically, the switching valve 270 has one inlet and two outlets. The inlet is connected to the filtered water outlet 6102 of the lint filtering device 600 through a communication pipeline 280. One of the outlets is connected to a return water pipeline 230, and the other outlet is connected to a drainage pipeline 250.

[0050] During the operation of the washing device, the switching valve 270 can be used to control either the return water pipeline 230 or the drainage pipeline 250 to be conducted with the filtered water outlet 6102 of the lint filtering device 600. Specifically, during the main washing stage and the rinsing stage, the on-off valve 241 is closed, and the switching valve 270 conducts the filtered water outlet 6102 of the lint filtering device 600 and the return water pipeline 230. The water pump 400 operates continuously or intermittently, pumps water from the water storage barrel 100 for filtration, and then sends it back to the water storage barrel 100 for cyclic filtration washing / rinsing. When external drainage is required, the on-off valve 241 remains closed as well. The switching valve 270 conducts the filtered water outlet 6102 and the drainage pipeline 250. The water pump 400 operates continuously to pump out the water in the water storage barrel 100. After being filtered by the lint filtering device 600, the water is discharged from the washing device.

[0051] The switching valve 270 also has a fully closed state. At this time, neither of the two outlets of the switching valve 270 is conducted with the inlet of the switching valve 270, thereby completely blocking the water outlet from the filtered water outlet 6102 of the lint filtering device 600. When the lint collected inside the lint filtering device 600 needs to be discharged, the washing device controls the switching valve 270 to be in the fully closed state and opens the on-off valve 241, thereby conducting the lint discharge water path 240. The lint water inside the lint filtering device 600 can then drain into the lint collection device 500 along the lint discharge water path 240 under the action of gravity.

[0052] As a specific implementation manner, when the washing device performs a lint discharge operation of discharging lint water from the lint filtering device 600 to the lint collection device 500, the water pump 400 remains in the closed state. At this time, only the accumulated water and lint inside the lint filtering device 600 are discharged into the lint collection device 500.

[0053] As another specific implementation manner, when the washing device performs a lint discharge operation, it also controls the water pump 400 to operate continuously or intermittently for a period of time, pumps a part of the water from the water storage barrel 100 into the lint filtering device 600, and flushes the lint collected inside the lint filtering device 600, so that the lint can be discharged into the lint collection device 500 more fully along with the water flow.

[0054] In a preferred solution of this embodiment, the switching valve and the on-off valve are integrally arranged as an integrated valve. The integrated valve has a first valve chamber belonging to the switching valve and a second valve chamber belonging to the on-off valve, and the first valve chamber and the second valve chamber are independent of each other. The integrated valve is also provided with two motors, and the on-off states of the switching valve and the on-off valve are controlled by the two motors one by one. The arrangement of the integrated valve helps to save the installation space and makes the internal structure of the washing equipment more compact.

[0055] In the detailed solution of this embodiment, the lint filtering device 600 is arranged in the top area inside the cabinet 10, and the lint collecting device 500 and the water pump 400 are both arranged in the bottom area inside the cabinet 10. The bottom of the water storage cylinder 100 is connected to the pump hose 260, and is connected to the water inlet end of the water pump 400 through the pump hose 260. The water outlet end of the water pump 400 is connected to the upwardly extending intermediate pipeline 220, and the upper end of the intermediate pipeline 220 is connected to the water inlet 6101 of the lint filtering device 600. The return water pipeline 230 extends from an outlet of the switching valve 270 to the water storage cylinder 100, and returns water into the cylinder from the top area of the water storage cylinder 100.

[0056] In a further solution of this embodiment, the lint collecting device 500 includes a housing 510 and a collecting assembly 560 arranged inside the housing 510. The water inlet 511 is arranged on the housing 510, and the water outlet 512 is also arranged on the housing 510. The collecting assembly 560 divides the inside of the housing 510 into an outer cavity and an inner cavity. The water inlet 511 is directly communicated with the inner cavity, and the lint water discharged from the lint filtering device 60 enters the inner cavity directly through the water inlet 511. The collecting assembly 560 has a filtering structure, such as a filter screen, which can intercept the lint in the lint water, so as to collect the lint in the inner cavity. The water without lint can enter the outer cavity through the filtering structure on the collecting assembly 560 and be discharged from the lint collecting device 500 through the water outlet 512.

[0057] In a specific solution, the water outlet 512 of the lint collecting device 500 is communicated with the water pump 400. After the lint is filtered out in the lint collecting device 500, the lint water can sequentially pass through the intermediate pipeline 220, the lint filtering device 600, the connecting pipeline 280, the switching valve 270, and the drainage pipeline 250 by the driving force of the water pump 400, and finally be discharged from the washing equipment.

[0058] In this embodiment, the collection component 560 is detachably installed inside the housing 510 of the lint collection device 500. When a large amount of lint is collected inside the collection component 560, especially when its interior is almost filled with lint, the filtering efficiency of the collection component 560 for lint water will be affected, and even cause the water flow to be unable to pass through the filtering structure on the collection component 560 and drain out. At this time, the user can remove the collection component 560 for cleaning, or directly replace it with a new collection component 560 to ensure that the lint collection device 500 can be used normally when the washing device runs next time.

[0059] However, the lint collection device 500 is installed inside the cabinet 10 of the washing device, and the user cannot directly observe the lint collection situation therein and can only clean it regularly. However, during the use of the washing device, it is inevitable that the user forgets to clean the lint collection device 500, which will affect the use effect of the washing device.

[0060] For this reason, the washing device of this embodiment is further provided with a detection device 800, which can be triggered when the filtering ability of the lint collection device 500 decreases. The control system of the washing device can obtain the state of whether the detection device 800 is triggered, and then send an alarm message according to whether the detection device 800 is triggered to prompt the user to clean the lint collection device 500.

[0061] In this embodiment, the filtering ability of the lint collection device 500 specifically refers to the remaining capacity of the lint collection device 500. When the remaining capacity of the lint collection device 500 is sufficient, the lint water entering the lint collection device 500 can quickly pass through the collection component 560, so that after filtering out the lint therein, it enters the outer cavity and finally drains out of the lint collection device 500. When a relatively large amount of lint has been collected inside the lint collection device 500 and it is close to the state of being filled with lint, it causes the remaining capacity of the lint collection device 500 to decrease and the filtering ability to decrease. At this time, most of the filtering structure on the collection component 560 is covered with lint, resulting in the water flow being unable to pass through, and then the efficiency of the lint water passing through the collection component 560 is greatly reduced, and the user needs to clean the lint collection device 500.

[0062] As a specific implementation manner of this embodiment, the detection device 800 is triggered by the change in the liquid level height inside the lint collection device 500, so as to reflect the decrease in the filtering ability of the lint collection device 500. Specifically, when the liquid level height inside the lint collection device 500 rises, the detection end of the detection device 800 can be triggered to be in contact with water and conduct.

[0063] More specifically, the water inlet 511 of the lint collection device 500 is arranged at a position close to the top, and the detection end of the detection device 800 is arranged at the water inlet 511 of the lint collection device 500. When the liquid level height in the lint collection device 500 is higher than the lowest position of the water inlet 511, the detection end comes into contact with water and conducts electricity, and the control system of the washing device then receives the signal that the detection device 800 is triggered.

[0064] Specifically, the housing 510 of the lint collection device 500 is approximately cylindrical, and the water inlet 511 is arranged on one of the end walls of the housing 510 and close to the top area. The water inlet 511 is formed by the end wall of the housing 510 extending horizontally to form a cylindrical structure for connecting the lint discharge water path 240. The detection device 800 includes two steel needles 810 arranged at intervals. The lower ends of the steel needles 810 serve as the detection ends of the detection device 800 and extend into the cylindrical structure of the water inlet 511. When there is lint water passing through or staying at the water inlet 511, the two steel needles 810 come into contact with the water at the water inlet 511 simultaneously and conduct electricity, so that the control system of the washing device receives the signal that the detection device 800 is triggered.

[0065] In this way, when a large amount of lint is collected in the lint collection device 500, resulting in a decrease in its filtering ability and a decrease in the remaining capacity, the water entering the lint collection device 500 cannot be quickly filtered and discharged, which will cause the liquid level in the lint collection device 500 to exceed the height where the water inlet 511 is located, causing the two steel needles 810 to contact the lint water and conduct electricity, triggering the detection device 800.

[0066] As another specific implementation manner, the pressure change in the lint collection device is used to trigger the detection device, thereby reflecting the decrease in the filtering ability of the lint collection device. Specifically, when the pressure in the lint collection device increases, the detection device can be triggered to act, and the control system of the washing device then receives the signal that the detection device is triggered.

[0067] For example, the detection device can detect the water pressure in the inner bottom area of the lint collection device. When a large amount of lint is collected in the lint collection device, resulting in a decrease in its filtering ability, the lint water entering the lint collection device will stay inside the lint collection device, and then the water pressure at the bottom of the lint collection device will remain at a relatively high level for a long time. In this case, the water pressure magnitude sensed by the detection device continuously remains at an abnormal level higher than the normal range, and the control system of the washing device receives the abnormal water pressure signal transmitted by the detection device and records it as the detection device being triggered once. Among them, the normal range refers to the pressure magnitude that can be detected when there is basically no accumulated water in the lint collection device.

[0068] In a detailed solution, the detection device is a pressure sensor, and the pressure sensor is installed inside the wire debris collection device, near the bottom area of the wire debris collection device.

[0069] In another detailed solution, the detection device includes an air duct, an air chamber, and a detection element. Among them, the air chamber is connected to the bottom area of the wire debris collection device through the air duct, and the detection element can detect the air pressure in the air chamber, and the air pressure reflects the water pressure at the bottom of the wire debris collection device.

[0070] However, it can be understood that the factors that can trigger the detection device 800 are relatively complex. In addition to the situation where the filtering ability of the wire debris collection device 500 decreases, there are also other situations that may trigger the detection device 800 and cause false alarms. For example, if the wire debris water flow discharged into the wire debris collection device 500 at one time is relatively large, it will also cause the water storage volume in the wire debris collection device 500 to rise rapidly, and it takes a certain amount of time to completely filter and discharge the wire debris water. At this time, the detection device 800 will also be triggered.

[0071] In response to the above problems, the washing equipment of this embodiment reminds the user to clean the wire debris collection device 500 by executing the following control method.

[0072] After the washing equipment finishes running the washing program, in response to the number of times the detection device 800 is triggered during this operation, it controls whether to send an alarm message to clean the wire debris collection device 500.

[0073] Furthermore, the washing equipment obtains the number of times the detection device 800 is triggered during this operation within a preset stage. If it is greater than or equal to the preset number of times, it sends an alarm message to clean the wire debris collection device 500.

[0074] Preferably, during the operation of the control system of the washing equipment, or at least when running to the preset stage, it obtains the state of the detection device 800 in real time. If the detection device 800 is in a triggered state and the duration exceeds the set duration threshold, that is, if the control system continuously receives the signal that the detection device 800 is triggered within the preset stage and the duration exceeds the set duration threshold, it records that the detection device 800 is triggered once within the preset stage. In this way, especially for the solution where the steel needle 810 is set at the water inlet 511 as the detection device 800, it can avoid the problem that the residual wire debris water in the wire debris discharge water path 240 just passes through the water inlet 511 within the above preset stage, thereby triggering the detection device 800 and causing misjudgment.

[0075] During the operation of the washing device, the control method of this embodiment counts the status of whether the detection device 800 is triggered in a preset stage. Only when the detection device 800 is triggered multiple times, the washing device will send out an alarm message, effectively avoiding the problem of low accuracy of the detection device 800 and high false alarm probability caused by single detection and alarm, and providing a better user experience.

[0076] In a further solution, after the washing program of this operation of the washing device ends, it is judged whether the number of times the detection device 800 is triggered within the preset stage is greater than a preset number. When the washing device judges that the number is greater than or equal to the preset number, instead of immediately sending out an alarm message, the alarm message is sent in the standby stage before the washing device starts the next washing program.

[0077] In a specific case, if the washing device shuts down after running the current washing program, then after the next startup, the washing device will send out an alarm message to remind the user to clean the lint collection device 500, and then start the washing program.

[0078] In another specific case, after the washing device runs the current washing program and does not shut down, the user still needs to use the washing device to run the next washing program again. At this time, the user will operate the washing device to set the washing program, or if continuing to run the same washing program, may directly trigger the program start instruction to control the start of the washing program. In this case, after the washing device finishes running the previous washing program and judges that an alarm message needs to be sent, if a program setting instruction or a program start instruction is received, an alarm message to clean the lint collection device 500 will be sent first to remind the user.

[0079] As a specific implementation manner, the washing device has a display board, and an alarm message is sent through the display board to remind the user to clean the lint collection device 500. For example, the display board can display the alarm message in the form of text or icons, and can also cooperate with the flashing of an indicator light and the beeping of a buzzer for reminder.

[0080] In the solution of this embodiment, when the washing device sends out an alarm reminder, the actual state of the lint collection device 500 is close to being filled with lint, but not completely blocked by lint, that is, the lint water entering the lint collection device 500 can still be filtered and discharged at a slower speed, rather than the lint collection device 500 being completely unable to drain water anymore. The washing device waits until a new washing program needs to be run to remind the user to clean the lint collection device 500, rather than immediately reminding after the end of this washing, leaving time for the residual water in the lint collection device 500 to drain, and avoiding the user from disassembling the collection component 560 in the lint collection device 500 when there is a large amount of residual water in it.

[0081] In a further solution of this embodiment, during the washing process of the washing device, at least one lint discharge operation is performed by the lint filter device 600 to drain water to the lint collection device 500. Since the steel needle 810 of the detection device 800 is inserted into the water inlet 511, it can be understood that when lint water enters from the water inlet 511, the detection device 800 will also be triggered, but this does not necessarily mean that the filtering capacity of the lint collection device 500 is low.

[0082] To this end, the washing device staggers the execution of the preset stage and the lint discharge operation to avoid counting the triggering of the detection device 800 by the water flow in the lint discharge operation into the number of times the detection device 800 is triggered, thereby causing a false alarm.

[0083] As a specific embodiment, the washing procedure at least includes a main wash stage, a main wash drainage and dehydration stage, a rinse stage, a rinse drainage and dehydration stage, and a final dehydration stage. Among them, after the washing equipment has completed water intake in the main wash stage and the rinse stage, the water pump 400 is driven to guide water to the wire dust filter device 600 for circulating filtration washing / rinsing, and the on-off valve 241 remains closed during this process. In the main wash drainage and dehydration stage and the rinse drainage and dehydration stage, when the washing equipment performs a drainage operation, the water pump 400 is driven to guide water to the wire dust filter device 600, and the washing water is filtered and then discharged. After the drainage operation is completed, the wire dust discharge operation can be performed, that is, the on-off valve 241 is opened, and the wire dust collected in the wire dust filter device 600 is discharged into the wire dust collection device 500 along with the water flow.

[0084] The preset stages include a standby stage before the washing program is started, a main wash stage of the washing program, and a rinsing stage of the washing program. At the same time, the preset number of times is set to two or three times, preferably three times. That is, in the preferred embodiment, if the control system of the washing device receives a signal that the detection device 800 is triggered in the above-mentioned standby stage, main wash stage, and rinsing stage, it will issue an alarm message in the standby stage before the next washing program is started.

[0085] In the standby stage, the washing machine has not yet added water to the water drum 100. Under normal circumstances, there will be no process of discharging lint water into the lint collecting device 500. The signal that the detection device 800 is triggered is received at this stage, most likely because the lint water discharged during the previous washing program has not been completely discharged. In the main wash stage and the rinsing stage, since the on-off valve 241 remains closed, the lint filtering device 600 will not discharge lint water into the lint collecting device 500. Therefore, if the signal that the detection device 800 is triggered is received during the washing stage or the rinsing stage, it means that the lint water discharged before the above stage has not been completely discharged.

[0086] In the standby stage, the main washing stage, and the rinsing stage of the washing device in this embodiment, it is respectively recorded whether the control system receives the signal that the detection device 800 is triggered. If it is finally recorded that the detection device 800 is triggered three times, it indicates that the current efficiency of the lint collection device 500 in discharging lint water is very low, and the remaining capacity, that is, the filtering capacity is insufficient. At this time, the washing device will send an alarm message before starting the next washing program to remind the user.

[0087] In a further solution of this embodiment, the washing device also obtains the number of times the washing program has been run. When the number of times of operation is greater than or equal to the first threshold, the washing device controls whether to send an alarm signal in response to the number of times the detection device 800 is triggered during this operation.

[0088] Specifically, as shown in Figure 4 and Figure 5 , the washing device accumulates the number of times the washing program has been run, that is, each time the washing program is completed, the number of times of operation increases by one. After the washing device is powered on, it obtains the number of times of operation recorded at the previous shutdown. If it is greater than or equal to the first threshold, it will respectively record whether the control system receives the signal that the detection device 800 is triggered in the subsequent standby stage, main washing stage, and rinsing stage, so as to control whether to send an alarm message. If the number of times of operation is less than the first threshold, the washing device operates the washing program normally and does not respond to the signal that the detection device 800 is triggered.

[0089] It can be understood that for the situation where the washing device does not shut down and runs two or more washing programs continuously, the washing device updates the number of times of operation when ending the previous washing program, and then if it receives a program setting instruction or a program start instruction, it determines whether to respond to the signal that the detection device 800 is triggered according to the updated number of times of operation.

[0090] Normally, it takes the washing device to run multiple washing programs for the lint collection device 500 to be filled with lint. Therefore, when the number of times the washing device runs the washing program is small, there will be no problem of insufficient filtering capacity of the lint collection device 500. The solution of this embodiment responds to the signal that the detection device 800 is triggered when the number of times the washing program has been run reaches the first threshold, further avoiding false alarms caused by inaccurate detection of the detection device 800.

[0091] Further, after the washing device sends out an alarm message for cleaning the lint collection device 500, it controls the cleared number of times of operation. After the user receives the alarm message sent by the washing device, the user will clean the lint collection device 500. After the cleaning is completed, the filtering capacity of the lint collection device 500 returns to the initial state. Therefore, after the washing device clears the number of times of operation of the washing program after sending out the alarm message and then accumulates the number of times of operation again, the problem that the washing device continuously alarms due to the detection error of the detection device 800 will not occur even if the user has cleaned the lint collection device 500.

[0092] In a further aspect of this embodiment, when the washing device determines that the number of times of operation of the washing program reaches the second threshold, it sends out an alarm message for cleaning the lint collection device 500 during the standby stage before starting the washing program next time, and controls the cleared number of times of operation. Wherein, the second threshold is greater than the first threshold.

[0093] It can be understood that in this embodiment, when the number of times of operation of the washing program reaches the second threshold, regardless of whether the control system of the washing device receives the signal that the detection device 800 is triggered in the above-mentioned preset stage, the washing device will send out an alarm message during the standby stage before starting the washing program next time.

[0094] Combined with Figure 4 As shown in the figure, as a specific implementation manner, after the washing device finishes the current operation, if the number of times the detection device 800 is triggered recorded is less than three, the number of times of operation is updated, and then it is determined whether the updated number of times of operation reaches the second threshold. If so, before starting the washing program next time, the washing device will send out an alarm message to remind the user to clean the lint collection device 500. If not, the washing device does not alarm, and records whether the control system receives the signal that the detection device 800 is triggered in each preset stage during the next operation.

[0095] Combined with Figure 5 As shown in the figure, as another specific implementation manner, the washing device obtains the number of times of operation of the washing program during the standby stage before starting the washing program. If the number of times of operation is greater than the second threshold, it sends out an alarm message for cleaning the lint collection device 500. If the number of times of operation does not reach the second threshold, the washing program can be started normally, and whether the washing device responds to the signal that the detection device 800 is triggered is controlled according to whether the number of times of operation reaches the first threshold.

[0096] In the above solution, the washing device combines two detection indicators, namely, the number of times the washing program has been run and whether the detection device has been triggered multiple times, to control whether to send an alarm message for cleaning the lint collection device 500. In particular, after the washing device has run the washing program multiple times, it can ignore the detection situation of the detection device 800 and directly send an alarm signal before the next start. Since a certain amount of lint is collected inside the lint collection device 500 each time the washing program runs, after the washing device has continuously run the washing program multiple times, it automatically controls to give an alarm reminder before the next run, which can avoid inaccurate detection by the detection device 800 and thus the problem that the alarm is not triggered when the lint collection device 500 needs to be cleaned.

[0097] In this embodiment, through a large number of test experiments on different types of clothes and different washing programs in advance, the maximum capacity of the lint collection device 500 is determined, and then the specific values of the first threshold and the second threshold are set according to the maximum capacity. Among them, when the number of times the washing device completely runs the washing program is less than the first threshold, the amount of lint collected in the lint collection device 500 should basically not affect the filtering efficiency of the collection component 560 for lint water. And when the number of times the washing device completely runs the washing program is less than or equal to the second threshold, the amount of lint collected in the lint collection device 500 should not block the collection component 560.

[0098] As a specific implementation manner, the first threshold is set to 20, and the second threshold is set to 25. When the washing device operates the washing program normally, it can at least filter the discharged lint water through the lint collection device 500 in 26 to 30 consecutive runs of the washing program, without the problem that the lint collection device 500 is filled with lint and the lint water cannot be filtered and discharged.

[0099] In a further solution of this embodiment, the control method further includes: after the washing device sends an alarm message, it determines whether the lint collection device 500 has been cleaned.

[0100] When it is determined that the lint collection device 500 has been cleaned, the washing device can operate the washing program normally, and in subsequent operations, it re-accumulates the number of times the washing program has been run, and controls when to send an alarm message for cleaning the lint collection device 500 again according to the number of times the washing program has been run and the number of times the detection device 800 has been triggered during the operation.

[0101] If the washing device determines that the lint collection device 500 has not been cleaned, then it only starts the washing program in response to the first program start instruction received after the alarm message is sent. After the current washing program runs to completion, the washing device no longer responds to the program start instruction received again.

[0102] Further, when the washing device determines that the lint collection device 500 has not been cleaned, after the first washing program ends after the alarm information is sent, when the washing device is powered on again or receives a program start instruction again, it sends the alarm information for cleaning the lint collection device again.

[0103] In the above solution, through the setting of the structure of the detection device 800 and the value of the second threshold, after the washing device sends the alarm information, the washing device can still run a complete washing program, and during the operation, the lint collection device 500 receives the lint water discharged from the lint filtering device 600 for filtering and collects the lint therein, without the problem that the lint collection device 500 is filled with lint and cannot drain water.

[0104] Adopting the above solution, when the user receives the alarm information sent by the washing device, the user can choose to clean the lint collection device 500 immediately according to the actual situation, or first use the washing device to complete a laundry and then clean the lint collection device 500. In this way, when the user is eager to use the washing device, there will be no problem that the lint collection device 500 must be cleaned first before washing, and the user experience is better.

[0105] After the user completes this laundry, since a certain amount of lint has been newly collected inside the lint collection device 500, the washing device does not respond to the program start instruction, which can avoid the washing device from running the washing program again, and the lint collection device 500 may overflow due to the inability to filter and drain the lint water.

[0106] As a specific implementation manner of this embodiment, a "confirm replacement" key is provided on the display board of the washing device. After the user cleans the lint collection device 500, by triggering the "confirm replacement" key, the information that the lint collection device 500 has been cleaned is fed back to the washing device. Correspondingly, in the above solution, the control system of the washing device determines whether the lint collection device 500 has been cleaned according to whether it receives the signal that the "confirm replacement" key is triggered.

[0107] Specifically, after sending the alarm information, if it receives the signal that the "confirm replacement" key is triggered, when the washing device receives the program start instruction again, it can run the washing program normally, and control whether to send the alarm information according to the newly accumulated number of times the washing program has been run and whether it receives the signal that the detection device 800 is triggered during the operation at the preset stage.

[0108] If the washing device does not receive the signal that the "confirm replacement" key is triggered, that is, it receives the program start instruction, then it can run a washing program once according to the received program start instruction. However, after the end of this washing program, the washing device no longer responds to the program start instruction, that is, the "start" key on the display panel triggered by the user is invalid at this time. Further, if the washing device receives the signal that the "start" key is triggered at this time, it is not allowed to run the washing program, and an alarm message for cleaning the lint collection device 500 is displayed to the user through the display panel to remind the user to manually clean the lint collection device 500.

[0109] The washing device provided in this embodiment can use the lint collection device 500 to collect the lint generated during the washing process, preventing the lint from being directly discharged and causing the problem that the microplastics therein enter the ecological cycle. By setting the detection device 800, the situation of lint collection inside the lint collection device 500 can be obtained. The structure and detection principle of the detection device 800 are simple and easy to implement. Combining with the control logic of multi-point detection and combining with the number of running times of the washing program, the problem of insufficient detection accuracy of the detection device 800 itself is overcome, and the alarm message can be sent more accurately to remind the user to clean the lint collection device 500, improving the user experience.
