Description

Control method of washing equipment and washing equipment

Technical field

The invention belongs to the technical field of washing equipment, and specifically relates to a control method of washing equipment and washing equipment.

Background technique

Washing equipment used to clean clothes, such as a washing machine, during the washing process of clothes, due to the friction between the clothes and the clothes and the washing machine itself, lint will fall off the clothes and mix into the washing water. If the lint in the washing water cannot be removed, it is likely to adhere to the surface of the clothes after the washing is completed, affecting the cleaning effect of the clothes. For this reason, existing washing machines are equipped with a filter for filtering lint. During the washing process, the washing water is continuously passed through the filter to remove lint from the washing water.

However, filtered impurities such as lint shavings will continue to accumulate in the filter, which will cause the filter to become clogged and unable to achieve the filtering function in the long run. The filter is generally installed inside the washing machine. Users cannot directly observe the accumulation of filtered impurities and can only clean it regularly. However, if the user washes a large amount of lint off over a period of time, 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 do laundry, the filter will not be able to perform the filtering function, which will affect the cleaning effect of the clothes.

In recent years, the concept of microplastics has been proposed in the field of environmental protection and has gradually received increasing attention. Research has found that an important source of microplastics is wastewater discharged from household washing machines. This is because with the popularity of chemical fiber fabrics, the clothing fibers shed during the washing process are discharged with the drainage water of the washing machine and become microplastics mixed into the natural water environment. Microplastics directly enter the ecological cycle with drainage water, and will eventually accumulate in the human body through the natural biological chain, which may have an impact on human health. To this end, relevant standards have been established in some areas for the content of microplastics in washing machine drainage. Once the filter is unavailable and the washing machine is running for laundry, the lint that falls off the clothes may be directly discharged with the drainage water of the washing machine, resulting in a large amount of microplastics in the drainage of the washing machine, which cannot meet the emission standards.

In view of this, the present invention is proposed.

This avoids the situation where the filtration capacity of the filtration module is insufficient and cannot realize the filtration function during the laundry process, thereby affecting the laundry washing effect.

In the present invention, the washing equipment obtains its filtration capacity during the working process of the filtration module. When it is judged that the filtration capacity is insufficient, it can be controlled in time. The filter module stops working, or the total working time of the filter module is reduced, so as to avoid forcing the filter module to work even when the filter module's filtering capacity is exhausted, which may cause the failure of the washing equipment.

In the present invention, the washing equipment can determine whether the filtration capacity of the filtration module meets the needs of this operation before starting operation, and prompt when the filtration capacity is insufficient to run this washing program, thereby avoiding the need for the washing equipment to adjust the filtration capacity of the filtration module. If the washing process is insufficient, the filtration function cannot be realized, which will affect the cleaning effect of clothes.

In the present invention, the washing equipment can compare the minimum filtration capacity required by the washing program to complete the filtration working conditions with the filtration capacity of the filter module to determine whether the washing program can be run. Especially in the setting stage of the washing program, by judging whether the washing program can be run, it can be avoided that the filtration capacity of the filter module cannot meet the washing program set by the user.

In the present invention, the filter device can independently clean the filter impurities during the operation of the washing program, and can also discharge the accumulated filter impurities outward to prevent the accumulation of filter impurities from causing clogging of the filter device, thus ensuring that the filter device always has sufficient filtering capacity. In order to realize the filtration function, it ensures the filtration effect during the operation of this washing program.

In the present invention, the washing equipment obtains the number of uses of the filter module and predicts the current working status of the filter module based on the number of uses, such as whether the filtering effect is reduced, without directly detecting the working status of the filter module. When the number of uses of the filter module reaches the preset number and it is detected that the filter module has been taken out, the number of uses can be controlled to be cleared. This prevents the washing equipment from still judging that the current filtering effect of the filter module is not good after the user takes out the filter module for cleaning. , which may trigger false alarms.

Embodiment 1

As shown in FIGS. 1 and 2 , the washing equipment in this embodiment includes a water tank 100 and a filter module for filtering water in the water tank 100 . The washing equipment may be a washing machine, a washer-dryer, a care machine and other washing equipment with a clothes cleaning function.

When the washing equipment is washing clothes, the water in the water tank 100 is introduced into the filter module for circulation filtration, which can filter out impurities such as lint in the water and improve the cleaning effect of the clothes. When the washing equipment is drained, the water in the water tank 100 is introduced into the filter module, and is filtered by the filter module before being discharged outward. This can avoid filter impurities carrying microplastics being discharged directly.

In this embodiment, the filter module includes a filter device 600 connected to the water cylinder 100. The filter device 600 receives the water in the water cylinder 100 for filtering, and outputs the filtered water with filtered impurities removed. The filtered water It can be returned to the water tank 100 along the water channel structure inside the washing equipment, or discharged from the washing equipment along the drainage water channel structure.

Specifically, the washing equipment includes a circulating filter pipeline, the water inlet end and the water outlet end of which are respectively connected with the water tank 100. The filter device 600 is disposed on the circulation filtration pipeline, and a circulation pump 400 is also disposed on the circulation filtration pipeline. When the washing equipment is washing clothes, the circulation pump 400 is turned on to drive the water in the water tank 100 to flow along the circulation filter pipeline into the filter device 600 and return to the water tank 100 after being filtered.

In detail, the bottom of the water container 100 is connected to the water container drain pipe 260, the water container drain pipe 260 is connected to the inlet end of the circulation pump 400, the outlet end of the circulation pump 400 is connected to the circulation pipeline 220, and the circulation pipeline 220 is connected to the filter device 600. Water inlet 6101 connection. The filtered water outlet 6102 of the filtering device 600 is connected to the water tank 100 through the return pipe 230 . The water outlet end of the return pipe 230 is specifically connected to the water tank 100 On the window pad 110 at the mouth of the tube, water is returned to the water tank 100 through the window pad 110.

In a further solution of this embodiment, a switching device 270 is provided between the filtered water outlet 6102 of the filtering device 600 and the return water pipeline 230 , and the water inlet of the switching device 270 is connected to the filtered water outlet 6102 of the filtering device 600 . The switching device 270 has a first water outlet and a second water outlet, the first water outlet is connected to the return water pipeline 230, and the second water outlet is connected to the external drainage pipeline 250 for external drainage of the washing equipment. A switching mechanism is provided inside the switching device 270 for controlling the first water outlet and the second water outlet to selectively communicate with the water inlet.

Through the setting of the switching device 270, the washing equipment can realize two filtration functions: circulation filtration during the washing process and drainage filtration during the drainage process by arranging a filtering device 600 in the washing equipment. At the same time, circulation filtration and drainage filtration share the circulation pump 400 and part of the pipeline structure, which simplifies the waterway control structure inside the washing equipment. By controlling the conduction direction of the switching device 270, the function switching between circulation filtration and drainage filtration can be realized, and the control logic is simple.

In a further step of this embodiment, the filter device 600 has a self-cleaning function. The user does not need to remove the filter device 600 for manual cleaning. The filter device 600 can clean itself and discharge the filter impurities accumulated during the filtration process with the water flow. Specifically, the filtering device 600 is provided with a sewage outlet 6103 for discharging sewage to the outside. The filter module also includes a recovery device 500. The recovery device 500 is connected to the sewage outlet 6103 of the filtering device 600 and can receive the sewage discharged by the filtering device 600.

Through the setting of the recovery device 500, after the filter device 600 performs self-cleaning, the discharged sewage carrying filtered impurities can be discharged into the recovery device 500 instead of being directly discharged with the drainage of the washing equipment, thus avoiding the risk of microplastics in the filtered impurities being discharged. The problem of drainage water entering the ecological cycle.

Specifically, in this embodiment, the filtering device 600 includes:

The filter cavity 610 is provided with a water inlet 6101, a filtered water outlet 6102 and a sewage outlet 6103;

The filter mechanism 620 is rotatably arranged inside the filter cavity 610, and has a water outlet joint 621 that is rotatably and sealably connected to the filtered water outlet 6102;

The driving mechanism 660 is connected to the filtering mechanism 620 and is used to drive the filtering mechanism 620 to rotate in the filtering cavity 610 .

The filter mechanism 620 divides the interior of the filter cavity 610 into an outer cavity and an inner cavity, wherein the water inlet 6101 is connected to the outer cavity, and the filtered water outlet 6102 is connected to the inner cavity. The water in the water cylinder 100 enters the outer chamber through the water inlet 6101 under the action of the circulation pump 400, passes through the filter mechanism 620 and enters the inner chamber to achieve filtration. The filtered impurities carried in the water adhere to the outer wall of the filter mechanism 620 and are filtered out. The impurity-filtered water can flow out of the filtered water outlet 6102 through the water outlet connector 621 .

In detail, the filtering mechanism 620 includes a filter bracket and a filter mesh covering the filter bracket. One end of the filter bracket extends into the filtered water outlet 6102 to form a water outlet joint 621.

When it is necessary to clean the filter impurities inside the filter device 600, the driving mechanism 660 drives the filter mechanism 620 to rotate, which can stir the water flow in the filter cavity 610, so that the filter impurities attached to the outer wall of the filter mechanism 620 are removed under the dual effects of centrifugal force and agitation of the water flow. It is peeled off, blended into the water in the filter cavity 610, and then discharged with the water flow through the sewage outlet 6103 on the filter cavity 610. The sewage outlet 6103 is connected to a sewage pipeline 240, and the sewage is transported to the recovery device 500 through the sewage pipeline 240.

Cleaning particles 680 are also provided between the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620 for friction and collision with the water flow to clean the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620. During the filtration process, the cleaning particles 680 continuously rub against the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620 with the flowing water, causing the attached filter impurities to fall off, thereby preventing the deposition of filter impurities and preventing the filter mechanism 620 from being covered by filter impurities too quickly. Affect filtration efficiency. On the other hand, it also avoids the problem that the filter impurities attached after the filtration are too thick and adhere too firmly to the inner wall of the filter cavity 610 or the outer wall of the filter mechanism 620, making it difficult to remove the filter impurities when cleaning the filter device 600 later.

When the driving mechanism 660 drives the filter mechanism 620 to rotate in the filter cavity 610 to achieve self-cleaning, the cleaning particles 680 move in the filter cavity 610 under the action of the turbulent water flow, and rub against the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620. , thereby improving the stripping efficiency of filtered impurities, and the self-cleaning effect of the filter device 600 is better.

A baffle 690 is also provided in the filter cavity 610, and a water hole 691 is provided on the baffle 690. The cleaning particles 680 are arranged on one side of the baffle 690 (i.e., the left side in Figure 2), and the filtered water outlet 6102 and the sewage outlet 6103 on the filter cavity 610 are located on the other side of the baffle 690 (i.e., the right side in Figure 2). side).

Through the arrangement of the baffle 690, the cleaning particles 680 can be prevented from gathering toward the filtered water outlet 6102 during the filtration process. When the filter device 600 performs self-cleaning and discharges sewage, the filtered impurities carried by the sewage can pass through the baffle 690 through the water hole 691 and pass through the baffle 690. The sewage outlet 6103 is discharged, and the cleaning particles 680 are blocked by the baffle 690 and will not be discharged with the water flow from the sewage outlet 6103, thereby avoiding the loss of the cleaning particles 680. At the same time, it can also prevent the cleaning particles 680 from accumulating in the sewage outlet 6103, causing blockage of the sewage outlet 6103 and affecting the sewage discharge efficiency.

In this embodiment, a sewage control valve 241 is provided on the sewage pipeline 240 for controlling the opening and closing of the sewage pipeline 240 . When the washing equipment conducts water to the filter device 600 for filtering, the sewage control valve 241 is closed and the sewage pipeline 240 is cut off to ensure that the water entering the filter device 600 can flow out through the filtered water outlet 6102 after being filtered. When the sewage in the filtering device 600 needs to be discharged, the sewage control valve 241 is opened to connect the sewage pipeline 240 , and the sewage in the filtering device 600 can be discharged into the recovery device 500 .

Preferably, a return water control valve 231 is also provided outside the filtered water outlet 6102 of the filtering device 600 for controlling the connection between the filtered water outlet 6102 and the switching device 270 . When the filtering device 600 is filtering, the return water control valve 231 is in an open state. When the filtering device 600 is controlled to discharge sewage, the return water control valve 231 is closed so that the filtering device 600 cannot discharge water from the filtered water outlet 6102, thereby ensuring that the filtering device The sewage within 600 is fully discharged from the sewage outlet 6103.

In this embodiment, the control method of the washing equipment includes:

Get the current filtering capability of the filter module;

Further, after the washing equipment sends a prompt message, the current washing program is kept running and the water is directed to the filter module. In other words, the washing program currently running by the washing equipment is not affected by the judgment of the filtration capacity, and the washing equipment can still complete the operation of this washing program.

The prompt information in this embodiment is essentially used to remind the user that the filtering capacity of the filter module is insufficient and cannot meet the need for the washing equipment to operate again, but the washing program can run normally this time. Therefore, the prompt information may be similar to "the filtration capacity has decreased, please check the filtration module after completing the laundry."

In the above scheme, the first preset value is at least not less than the filtration capacity required by the washing equipment to complete this washing process. The washing equipment obtains the filtration capacity of the filtration module during its working process, and sends out a prompt message when the filtration capacity drops to a certain level, so that the user can be informed of the drop in filtration capacity of the filtration module in a timely manner, and can in time, such as in this washing program After completion, clean, maintain or replace the filter module. In this way, it is avoided that when the washing equipment runs the washing program again, the filtering capacity of the filter module is insufficient and the filtering function cannot be realized during the washing process, thereby affecting the washing effect.

In this embodiment, the filtration capacity of the filtration module specifically includes: the smoothness of the water outlet of the filtration device 600, and/or the remaining capacity of the recovery device 500. It should be noted that the smoothness of the water outlet may be the smoothness of the filtering device 600 filtering water and outputting filtered water, or the smoothness of the filtering device 600 discharging sewage to the outside.

Specifically, the smoothness of the filtered water output by the filtering device 600 can be reflected in the flow rate or water pressure at which the filtering device 600 filters the water and discharges the filtered water. As the filtering device 600 continues to filter, filtered impurities gradually accumulate inside the filtering device 600 and cover the outer wall of the filtering mechanism 620 . As the accumulation of filtered impurities increases, the area of the outer wall of the filtering mechanism 620 that can discharge water gradually decreases, and the flow rate and pressure of the discharged filtered water will gradually decrease accordingly. When the outer wall of the filtering mechanism 620 is completely covered, that is, when the filtering device 600 is completely blocked, the filtered water cannot be discharged outward, resulting in the filtration process being unable to continue.

The smoothness of the sewage discharged from the filtering device 600 is similar, which is reflected in the flow rate or water pressure of the sewage discharge. When there are too many filter impurities accumulated in the filtering device 600, due to the size restrictions of the sewage outlet 6103 and the sewage pipeline 240, the flow rate or water pressure of the discharged sewage will decrease to a certain extent. In severe cases, the sewage route will be blocked and the filtration will be affected. Self-cleaning function of device 600.

During the operation of the washing program, the washing equipment intermittently controls the filter device 600 to perform self-cleaning and discharge sewage to the recovery device 500, thereby preventing a large amount of filter impurities from accumulating in the filter device 600 and affecting the filtration efficiency. The amount of sewage received in the recovery device 500 gradually increases during the washing process, and the remaining capacity gradually decreases. If the recovery device 500 is filled with sewage, continuing to discharge sewage into it will cause the recovery device 500 to overflow, causing users to complain.

In a further solution of this embodiment, during the working process of the filtration module, the washing equipment determines the current filtration capacity of the filtration module by detecting the water level information in the recovery device 500 .

In a specific solution of this embodiment, the washing equipment detects the water level in the recovery device 500. If the water level is higher than the preset water level, it is determined that the current filtration capacity of the filter module is lower than the first preset value.

The water level in the recovery device 500 directly reflects the amount of sewage received in the recovery device 500. By detecting the water level in the recovery device 500, the remaining capacity in the recovery device 500 can be determined. When the water level in the recovery device 500 exceeds the preset water level, it means that the remaining capacity in the recovery device 500 is low and will reach a nearly full state after the current washing program is completed. The user is reminded to handle the received sewage in the recycling device 500 in a timely manner by issuing a prompt message to prevent the recycling device 500 from overflowing when the washing equipment is operated again. Water failure.

In detail, in order to ensure that this washing program can be completed without overflow, the remaining capacity of the recovery device 500 corresponding to the preset water level must be at least not less than the remaining capacity of the recovery device 500 required to complete this washing program.

Further, the recovery device 500 includes a housing 510 and a lint collection assembly 570 disposed inside the casing 510. The lint collection assembly 570 filters the sewage received by the recovery device 500 and collects filtered impurities in the water. The recovery device 500 can separate filter impurities from the sewage it receives, allowing users to directly process the collected filter impurities, avoiding the situation where filter impurities are mixed in water and cannot be effectively processed.

Specifically, the housing 510 is installed on the box 10 so as to be insertable/extractable, and a recovery chamber is formed inside. The upper side of the housing 510 is configured as an open structure. The wire scrap collection assembly 570 is installed at a certain height inside the housing 510 to divide the recovery chamber into a first chamber 531 and a second chamber 532 distributed up and down.

The lint collection assembly 570 may be a horizontally arranged frame and a filter screen laid on the frame. The water outlet end of the sewage pipeline 240 is connected to the first chamber 531. The sewage carrying filtered impurities enters the first chamber 531, is filtered by the filter of the lint collection assembly 570, and then enters the second chamber 532. The filtered impurities are collected in the first chamber 531. In the chamber 531 , that is, it is collected on the upper surface of the wire scrap collection component 570 .

Preferably, the lint collection assembly 570 is detachably installed inside the casing 510. When the user pulls the casing 510 out of the box 10, the lint collection assembly 570 can be removed from the casing 510 through the opening on the upper side of the casing 510. The inside of 510 is disassembled and taken out for cleaning. At this time, there is no need to completely remove the recovery device 500, making the operation more convenient.

Under normal circumstances, the sewage entering the recovery device 500 will soon be filtered by the lint collection assembly 570 and enter the lower second chamber 532, and the amount of sewage in the first chamber 531 will hardly contain water. The preset water level is higher than the installation height of the lint collection assembly 570. When it is detected that the water level in the recovery device 500 exceeds the preset water level, it is most likely that the lint collection assembly 570 is covered by filtered impurities and is blocked. As a result, sewage cannot enter the second chamber 532. At this time, a prompt message is issued to remind the user to clean the lint collection assembly 570 after the current washing process, so as to avoid overflowing of the recovery device 500 when the washing equipment is run again.

In another specific solution of this embodiment, the washing equipment detects the water level change rate in the recovery device 500. If the water level change rate is lower than the preset change rate, it is determined that the current filtration capacity of the filter module is lower than the first preset value. . It should be noted that detecting the water level change rate needs to be performed during the process of the filtering device 600 discharging sewage into the recovery device 500 .

After the filter device 600 performs self-cleaning, the cleaned filter impurities are discharged from the sewage outlet 6103 and enter the recovery device 500 along the sewage pipeline 240 . The faster the flow rate of sewage discharge, the greater the sewage flow rate, which is reflected in the change in water level height of the recovery device 500, that is, the higher the water level change rate.

The washing equipment detects the water level change rate in the recovery device 500 when the filter device 600 performs a sewage discharge operation. When the water level change rate is lower than the preset change rate, it means that the current flow rate of sewage discharged by the filtering device 600 is reduced, the flow rate is slowed down, and there may be a certain degree of blockage. At this time, the washing equipment sends a prompt message to the user that the filtering capacity is insufficient, thereby reminding the user to perform maintenance on the filtering device 600 after the end of this washing process.

Or, when the water level change rate detected by the washing equipment is the water level change rate in the second chamber 532 of the recovery device 500, the sewage continues to enter the recovery device 500 while the filter device 600 performs the sewage discharge operation. If the change rate of the water level in the second chamber 532 is lower than the preset change rate, it means that the lint collection assembly 570 is blocked, causing sewage to be unable to enter the second chamber 532 .

In this case, the remaining capacity in the first chamber 531 can enable the washing equipment to complete the current washing program, but overflow may occur when the washing program is run again. By issuing a prompt message to remind the user to promptly clean the lint collection assembly 570 after the current washing process, it is possible to avoid overflowing of the recovery device 500 when the washing equipment is run again.

In this embodiment, in order to detect the water level information in the recovery device 500, a water level detection device 580 is provided inside the recovery device 500.

A specific structure of the water level detection device 580 in this embodiment is shown in FIG. 3 , including a step structure 582 and multiple sets of water level probes 581 arranged on the step structure 582 . Specifically, the step structure 582 includes a plurality of step surfaces of different heights, each step surface is provided with a set of water level probes 581 , and each set of water level probes 581 includes two electrodes arranged at intervals.

As the water level in the recovery device 500 rises, each time it passes a step surface of the step structure 582, the lower end of the water level probe 581 on the corresponding step surface comes into contact with the water, causing the two electrode sheets to be connected. According to the on-off status of each set of water level probes 581, the current water level in the recovery device 500 can be determined.

Using the water level detection device 580 with the above structure, the water level in the recovery device 500 continues to rise, so that each group of water level probes 581 is turned on one by one to obtain the time when each group of water level probes 581 is turned on, and then According to different water level probe 581 is turned on The water level change rate is calculated from the difference between them. Alternatively, after any group of water level probes 581 is turned on, and after a set time has elapsed, the adjacent higher group of water level probes 581 has not been turned on, then it is determined that the current water level change rate is lower than the predetermined rate. Let the rate of change.

Another specific structure of the water level detection device 580 is shown in Figure 4. It is an electrode type water level detection device 583, which includes two electrode sheets that are arranged oppositely and extend vertically for a certain length. As the water level in the recovery device 500 changes, the length of the two electrode sheets immersed below the liquid surface changes, that is, the area of the opposite surfaces of the two electrode sheets covered by the liquid changes. This change causes the capacitance value between the two electrode sheets to change, and the water level in the recovery device 500 can be calculated based on the detected capacitance value.

Using the water level detection device 580 with the above structure, on the one hand, the specific water level height in the recovery device 500 can be obtained in real time, and the water level change rate can be calculated based on the detected real-time changes in water level height, making the water level detection in the recovery device 500 more accurate.

Figure 5 shows another specific structure of the filter module in this embodiment, which shows a top structural view of the recovery device 500. The lint collection assembly 570 is a filter structure that surrounds a collection cavity. The sewage discharged from the filter device 600 directly enters the inside of the collection cavity enclosed by the lint collection assembly 570. After being filtered by the lint collection assembly 570, it enters the inside of the housing 510 and is located on the lint. The space outside the chip collection assembly 570 is used to filter impurities and collect them in the collection cavity. The water level detection device 580 is disposed inside the side wall of the housing 510 to detect the water level information in the recovery device 500 .

Specifically, the water level detection device 580 can detect the water level in the space outside the wire scrap collection assembly 570 in the recovery device 500, determine the remaining capacity in the recovery device 500 based on the detected water level, and then determine whether the filtration capacity of the filter module is lower than the first level. default value.

The water level detection device 580 can also detect the water level change rate in the recovery device 500. When the detected water level change rate is lower than the preset change rate, it means that the lint collection assembly 570 is blocked to a certain extent, causing the received sewage to be unable to be filtered. The sewage flows to the outside of the lint collection assembly 570 , or the filtering device 600 is blocked to a certain extent, causing the sewage to be unable to be smoothly discharged into the recovery device 500 . Both of the above situations reflect the decline in the filtering capacity of the filter module.

In a further solution of this embodiment, the control method includes: the washing equipment starts to conduct water to the filtration module for filtration, and after a preset detection time, the current filtration capacity of the filtration module is obtained.

If the filtration capacity of the filtration module is greater than or equal to the first preset value, the washing program is maintained and water is directed to the filtration module.

In the above scheme, it is generally not the case that the filtration capacity of the filtration module drops significantly just after the washing equipment starts running. Therefore, in this embodiment, during a washing process, after a certain period of time has elapsed since the filter module filtered, the current filtering capacity of the filter module is obtained, thereby avoiding invalid detection in the early stages of filtering.

As shown in Figure 6, the control method of the washing equipment in this embodiment specifically includes the following steps:

S11. The washing program starts running;

S12. Execute the filtering function and guide water to the filtering device 600 for filtering;

S13. When the preset detection time is reached, detect the water level information in the recovery device 500;

S14. Evaluate the current filtration capacity based on the water level information in the recovery device 500;

S15. Determine whether the filtering capability is less than the first preset value. If so, execute step S16; otherwise, execute step S17;

S16. A prompt message is issued and the washing program continues to run.

S17. The washing program continues to run.

In the above-mentioned steps S16 and S17, continuing to run the washing program means continuing to run subsequent operations of the washing program according to the set program, and maintaining the filtering function of guiding water to the filtering device 600.

In a further solution of this embodiment, if the current filtering capacity is greater than or equal to the first preset value and the washing equipment does not send out a prompt message, then after the preset detection time has elapsed, the current filtering capacity of the filtering module is obtained again to determine whether to send out a prompt message. Prompt information.

Specifically, in the above control method, step S16 also includes: continuing to run the washing program until the end of the washing program. After step S17, step S18 is also included: determine whether the washing equipment is completed. If so, end the current control process; otherwise, return to step S13.

In the above solution, the washing equipment continuously detects the filtration capacity of the filter module during the operation of the washing program. Before the washing equipment is completed, once the filtration capacity is lower than the first and set conditions, a prompt message will be sent to remind the user, ensuring When the washing equipment is run again, the filtration function can operate normally.

In this embodiment, the washing equipment can obtain the smoothness of the water outlet of the filtering device 600 or the remaining capacity of the recovery device 500 during the operation of the washing program, and then determine whether the status of the filtering device 600 and the recovery device 500 is satisfactory for the next operation of the washing equipment. The filtration function is smoothly performed during the washing process. When the status of the filter device 600 and the recovery device 500 does not meet the next filtering function, the user can be reminded to clean, maintain or replace the filter device 600 or the recovery device 500 in time to ensure that the washing equipment does not run the washing program again. There will be a problem of filtering function failing.

Embodiment 2

As shown in Figures 1 and 7, the difference between this embodiment and the above-mentioned Embodiment 1 is that the washing equipment determines the current filtration capacity of the filtration module by detecting the flow rate of sewage discharged from the filtration device 600 to the recovery device 500.

Specifically, when the detected sewage flow rate is lower than the preset flow rate, it is judged that the current filtering capacity of the filter module is lower than the first preset value, and the washing equipment issues a prompt message.

The decline in sewage flow is mainly caused by the following two reasons.

The first reason is that when the interior of the filtering device 600 is clogged due to the accumulation of a large amount of filtering impurities, or when a part of the sewage pipe 240 is clogged due to the accumulation of filtering impurities, the discharge of sewage from the filtering device 600 into the recovery device 500 will be blocked, thereby causing the sewage to be discharged. Traffic drops.

When the washing equipment detects that the sewage flow rate drops below the preset flow rate, a prompt message is issued to remind the user to perform a timely check after the current washing is completed to avoid the next time the washing program is run, the sewage discharge route is blocked and the filtering device 600 cannot be implemented sewage discharge function.

The second reason is that the lint collection component 570 in the recovery device 500 is covered with filter impurities and is blocked, making it impossible to filter the received sewage. The sewage cannot enter the second chamber 532 through the lint collection assembly 570 and will gradually fill the first chamber 531 . When the recovery chamber inside the recovery device 500 is relatively sealed, when the first chamber 531 is filled or nearly full with sewage, the resistance encountered by subsequent sewage when entering the recovery device 500 becomes greater. If the filtering device 600 does not use additional driving force in the process of discharging sewage to the recovery device 500, but only relies on the gravity of the sewage itself to complete the sewage discharging operation, it will be difficult for the sewage to enter the recovery device 500, resulting in a decrease in the sewage flow rate.

When the washing equipment detects that the sewage flow rate drops below the preset flow rate, a prompt message is issued to remind the user to clean the recovery device 500 in time after the current washing is completed, so as to avoid the failure of the recovery device 500 due to being full the next time the washing program is run. Realize the sewage discharge function of the filtering device 600.

In order to check the sewage flow, the washing equipment of this embodiment is provided with a flow meter 243 on the sewage pipeline 240. The flow meter 243 is specifically arranged upstream of the sewage control valve 241, and can detect the sewage flow in the sewage pipeline 240, and then Determine the current filtering capability of the filter module.

Specifically, the control method of the washing equipment in this embodiment is shown in Figure 8, including the following steps:

S21. The washing program starts running;

S22. Execute the filtering function and guide water to the filtering device 600 for filtering;

S23. When the preset detection time is reached, detect the sewage flow in the sewage pipeline 240;

S24. Evaluate the current filtering capacity based on the sewage flow in the sewage pipeline 240;

S25. Determine whether the filtering capability is less than the first preset value. If so, execute step S26; otherwise, execute step S27;

S26. A prompt message is issued and the washing program continues to run.

S27. The washing program continues to run.

Among them, in step S26 and step S27, continuing to run the washing program means continuing to run subsequent operations of the washing program according to the set program, and maintaining the filtering function of guiding water to the filtering device 600.

In this embodiment, the washing equipment determines the filtration capacity of the filter module by detecting the sewage discharge flow rate, mainly to determine whether the sewage discharge of the filter device 600 itself is smooth and whether the lint collection assembly 570 in the recovery device 500 is clogged, thereby reminding the user in time Carry out cleaning and maintenance to ensure the working effect of the washing equipment for the next operation.

Embodiment 3

As shown in Figures 1 and 9, the difference between this embodiment and the above-mentioned Embodiment 1 is that the internal structure of the recovery device 500 is different.

Specifically, a first lint collection assembly 571 and at least one second lint collection assembly 572 are provided inside the recovery device 500 . The first lint collection component 571 and the second lint collection component 572 are independent of each other and can respectively receive and filter the sewage entering the recovery device 500 and collect filtered impurities in the sewage.

In this embodiment, the structures of the first lint collection assembly 571 and the second lint collection assembly 572 are basically the same, including a filter structure forming a collection cavity inside, and the sewage entering the recovery device 500 is directly passed into the collection cavity. After being filtered by the filter structure, it enters the main chamber 533 of the recovery device 500, and the filtered impurities in the sewage are collected in the collection chamber.

The water outlet end of the sewage pipeline 240 is directly connected to the collection chamber of the first lint collection assembly 571 , and a sewage branch 244 is connected between the water inlet end of the sewage pipeline 240 and the sewage control valve 241 . The waste discharge branch 244 is directly connected to the collection chamber of the second lint collection assembly 572, and a branch control valve 246 is provided thereon. When the branch control valve 246 is opened, the sewage branch 244 is opened, and the sewage discharged from the filter device 600 can bypass The first lint collection assembly 571 directly enters the collection cavity of the second lint collection assembly 572 along the sewage branch 244 .

The branch control valve 246 is a normally closed valve. When the filter device 600 filters and discharges filtered water, the drain control valve 241 and the branch control valve 246 are both closed, and the water in the filter device 600 will not flow through the drain port 6103 outflow. When the filter device 600 performs a sewage discharge operation, only the sewage control valve 241 is opened, and the discharged sewage flows along the sewage pipeline 240 to the first lint collection assembly 571 .

However, when the first lint collection assembly 571 is blocked and gradually filled with sewage, since it is difficult for sewage to enter the collection cavity of the first lint collection assembly 571, the branch control valve 246 can be opened to connect the sewage branch 244. , the discharged sewage can enter the recovery device 500 along the sewage branch 244.

In this embodiment, the washing equipment can also obtain the filtration capacity of the filtration module, and send out a prompt message when the filtration capacity is lower than the first preset value. Specifically, the filtration capability of the filtration module in this embodiment specifically refers to the filtration capability of the recovery device 500 for the received sewage.

When the washing equipment is running the washing program, the flow direction of the sewage discharged by the filter device 600 is obtained. If there is sewage flowing along the sewage branch 244 to the second lint collection component 572, it is judged that the current filtration capacity of the filter module is lower than the first predetermined sewage. Set value.

The first lint collection assembly 571 is the main collection assembly in the recovery device 500, and the second lint collection assembly 572 is an auxiliary collection assembly that is activated only when the first lint collection assembly 571 is blocked by filtered impurities. Therefore, when the washing equipment determines that the sewage flows to the second lint collection component 572, it means that the filtering capacity of the first lint collection component 571 has been exhausted, and the user needs to be reminded to clean it after the current washing process.

Specifically, the control method of the washing equipment in this embodiment is shown in Figure 10, including the following steps:

S31. The washing program starts running;

S32. Execute the filtering function and guide water to the filtering device 600 for filtering;

S33. Determine whether the second lint collection component 572 is enabled. If so, send a prompt message and then execute step S34. Otherwise, directly execute step S34;

S34. The washing program continues to run.

In a further solution of this embodiment, in order to control the opening of the branch control valve 246, a pressure detection element 245 is provided between the water inlet branch control valves 246 of the sewage branch 244, which can detect the water in the sewage branch 244. pressure.

When the sewage can smoothly enter the first lint collection assembly 571, there is almost no water in the sewage branch 244. Once the first lint collection component 571 is clogged, the sewage cannot enter the first lint collection component 571 and flows into the sewage branch 244. The branch control valve 246 is closed, which will cause the water pressure in the sewage branch 244 to increase rapidly. rise.

When the pressure detection element 245 detects that the water pressure rises, the washing equipment control branch control valve 246 opens, and the sewage can be discharged into the collection cavity inside the second lint collection assembly 572 .

Correspondingly, in step S33 of the control method of this embodiment, when the pressure detection element 245 detects a rise in water pressure, the branch control valve 246 can be opened, and at the same time, it is determined that the second lint collection component 572 has been activated, and a prompt message is issued. The user cleans the first lint collection component 571 after the current washing program.

In this embodiment, the recovery device 500 is provided with a first lint collection component 571 and a second lint collection component 572 respectively. When the first lint collection component 571 is clogged, the second lint collection component 572 can be activated to continue. Receive the sewage discharged by the filtering device 600 to avoid the situation that the filtering device 600 cannot realize the sewage discharge function. The washing equipment detects the water pressure of the sewage branch 244 by setting the pressure detection element 245. On the one hand, it can control whether to activate the second lint collection assembly 572. On the other hand, it can provide feedback to the control of the washing equipment when the second lint collection assembly 572 is enabled. system to achieve the purpose of sending reminder information in a timely manner.

Embodiment 4

This embodiment is a further limitation of the above-mentioned embodiments one to three. The washing equipment continues to run the washing program after sending the prompt message, and continues to use the filter module to implement the filtering function. After a certain period of time, the current filtering capacity of the filter module is obtained again.

If the filtration capacity is lower than the second preset value, the water supply to the filtration module is stopped, and the washing program continues until the end. Wherein, the second preset value is lower than the first preset value.

Specifically, in this embodiment, the second preset value is close to the complete exhaustion of the filtering capacity of the filter module. Since the setting of the first preset value is at least not lower than the filtration capacity required by the washing equipment to complete this washing process, under normal circumstances, if the filtration capacity of the filter module is not lower than the first preset value, the washing equipment can at least Complete this washing program while continuing to perform the filtering function. However, there may be some special circumstances that cause the filtration capacity of the filtration module to decline faster than expected, which may cause a malfunction if the filtration function continues to run while the washing program continues to run.

In the above solution of this embodiment, the washing equipment still obtains the filtering capacity of the filtering module after sending the prompt message. When it is judged that the current filtering capacity is not enough to complete the washing program, the execution of the filtering function is stopped, but the washing program remains Operating status. In this way, the laundry equipment can complete the laundry process without user intervention, making it more intelligent.

Furthermore, in this embodiment, if the filtering capacity obtained again is greater than or equal to the second preset value, the washing equipment continues to run the washing program and conducts water to the filtering device to perform the filtering function, and obtains the filtering device again after a certain period of time. Filtering capability, determine whether to stop the execution of the filtering function.

The above process is repeated until the obtained filtration capacity is lower than the second preset value or the washing program ends.

In this embodiment, after the washing equipment obtains that the filtration capacity of the filtration module is lower than the first preset value, it still intermittently obtains and compares the filtration capacity of the filtration module during subsequent washing program operations. When it is determined that the filtration capacity of the filtration module is When the filtration capacity is nearly exhausted but the washing program has not been completed, the filtration function can be automatically stopped but the washing program continues to run until the end. No user operation is required during the operation of the washing equipment, and there will be no operational failure caused by exhaustion of the filtration capacity of the filtration module.

Embodiment 5

As shown in Figures 1 and 11, the difference between this embodiment and the above-mentioned Embodiment 1 is that the current filtering capacity of the filter module includes the remaining number of uses of the filter module. When the remaining number of uses drops to the preset times, the washing equipment sends an alarm signal.

Specifically, the recovery device 500 in this embodiment is integrated with the detergent dispensing device, and may be disposed inside the water tank of the detergent dispensing device. After the recovery device 500 filters the received sewage, the filtered water enters the inside of the water tank. The sink is connected to the water tank 100 of the washing equipment, and the filtered water can be passed into the water tank 100 .

An insertable/extractable dispenser box is provided inside the sink. The dispenser box forms a detergent adding chamber and a recycling installation chamber that are isolated from each other. The detergent adding chamber and the recycling installation chamber are independently connected to the sink. The recovery device 500 is installed in the recovery installation cavity.

The user can pull out the dispenser box, add detergent into the detergent adding chamber, and then re-insert the dispenser box into the sink. The washing equipment can automatically put the detergent in the detergent adding chamber into the water tank when running the washing program. 100 in. When it is necessary to clean the recycling device 500 , the dispenser box is pulled out, and the lint collection assembly 570 in the recycling device 500 is removed for cleaning.

In this embodiment, according to the ability of the recovery device 500 to collect filtered impurities, it can be estimated that the recovery device 500 can run the washing program at the highest value from the initial state (that is, a state in which no filtered impurities are collected) until it is completely blocked by the filtered impurities. frequency.

Each time the washing equipment runs a washing program, in this embodiment, it is recorded that the number of times the recovery device 500 has been used increases by one. The washing equipment presets the total number of times S that the recovery device 500 can be used from the initial state. The total number of times S that can be used is not higher than the highest number of times that the above-mentioned washing equipment can run the washing program, that is, the number of times S1 of the recovery device has been used. Before reaching the total number of uses S, the recovery device 500 will not be completely blocked by filtered impurities.

The remaining usable times of the filter module in this embodiment specifically refers to the remaining usable times of the recovery device 500 , that is, the difference between the total number of times S that can be used and the number of times S1 has been used.

Generally, every time the user performs a pulling operation of the dispenser box, it means that the user has added detergent to the dispenser box, and the washing equipment will run a washing program. Therefore, in a further solution of this embodiment, the washing equipment accumulates the number of times the dispenser box is pulled out as the number of times S1 of the recovery device 500 has been used, and the remaining number of times of use S2=S-S1 of the recovery device 500 is calculated, that is, The number of remaining uses of the filter module. When the calculated number S2 drops to the preset number S0, the washing equipment will send out an alarm signal to prompt the user to clean the recovery device 500.

Through the above solution, the washing equipment can automatically remind the user to clean the recovery device 500 in time to avoid the washing equipment from running the washing process when the recovery device 500 is blocked, causing the sewage in the filtering device 600 to be unable to be discharged, affecting the filtration effect during the laundry process.

In detail, in this embodiment, the value of the preset number S0 is set to 0. When the user pulls out the dispenser box at a certain time, when the accumulated number S1 of the washing equipment reaches S, that is, when S2 drops to 0, the washing equipment will issue an alarm. Signal. The user can clean the recovery device 500 and then reinsert the dispenser box into the sink of the detergent dispenser.

Further, in this embodiment, when the washing equipment detects that the dispenser box is re-inserted, the currently accumulated number S1 is cleared to zero, and when it is detected again that the dispenser box is withdrawn, the accumulated number S1 is recorded as 1.

For example, the preset total number of times S of the washing equipment can be used is 20. Every time the user pulls the dispenser box, the number S2 calculated by the washing equipment is reduced by one. When the user pulls out the dispenser box for the 20th time, the washing equipment calculates S2=0 and sends an alarm signal. After the user cleans the recycling device 500 and inserts the dispenser box again, the current accumulated number S1 is cleared. When the washing equipment detects that the dispenser box is pulled out again, the current accumulated number S1 is recorded as 1. Of course, the preset value S of the total number of times that can be used can also be other values, such as any value in the range of 10 to 30.

It should be noted that in this embodiment, after the washing equipment sends an alarm signal and detects that the dispenser box is re-inserted, it directly performs the operation of clearing the current accumulated times S1 without detecting whether the recovery device 500 has been cleaned. That is to say, after the washing equipment sends out an alarm signal by default and the user cleans the recovery device 500, the dispenser box will be re-inserted into the sink.

However, since the washing equipment in this embodiment does not accumulate the actual number of times the washing program is run, but the number of times the dispenser box is pulled, there may be a situation where the user pulls the dispenser box multiple times but only runs the washing program once. . Alternatively, if the amount of lint shed from the clothes washed by the user is small, it is also possible that the cumulative number of pulls S1 of the dispenser box by the user reaches S, that is, the washing program has been run cumulatively S times, but the recovery device 500 still has a certain capacity. , can continue to receive sewage and collect filter impurities in the sewage.

In the above two situations, when the washing equipment sends an alarm signal, the user can choose not to clean the recovery device 500, but directly reinsert the dispenser box into the sink of the detergent delivery device to continue running the next washing program. But at this time, the washing equipment clears the current accumulated number of times S1, and the alarm will be triggered again only when the number of times the dispenser box is pulled is accumulated to S0 again.

However, since a certain amount of filtered impurities have been collected in the recovery device 500, before the total number of times the washing equipment runs the washing program reaches S0, the recovery device 500 may be blocked by the filtered impurities and cannot further receive the sewage discharged by the filter device 600. . But at this time, because the accumulated number S1 has not reached S0, the washing equipment will not alarm.

In order to avoid the above problem, in a further solution of this embodiment, the washing equipment can receive the user's instruction to adjust the total number of times that can be used, and adjust the value of the total number of times that can be used from the preset S to S'.

Specifically, after the washing equipment sends an alarm signal, if the user determines that the current recovery device 500 does not need to be cleaned, the dispenser box can be directly inserted into the sink of the detergent delivery device after completing the detergent putting operation. The user can then manually operate the washing equipment to set the value of the total number of times it can be used based on the current collection volume of filtered impurities in the recovery device 500. For example, the preset value of the total number of times it can be used is S=20, and the user can manually set the value of the total number of times it can be used. The value is adjusted to S'=5. In this case, the washing equipment re-accumulates the number of times the dispenser box is pulled out. When the dispenser box is pulled out for the fifth time, the alarm condition of S2=S’-S1=0 is triggered, and the washing equipment sends out an alarm signal.

In the above solution, the washing equipment provides an editable function of the total number of times the recovery device 500 can be used. If the user does not clean the recovery device 500 after the washing equipment alarms, the user can manually adjust the value of the total number of times the recovery device 500 can be used, reducing the number of times the washing equipment can be used. The number of times the washing program is run before the alarm is accumulated to ensure that the recovery device 500 will not be blocked during the washing process.

In a further solution of this embodiment, after the washing equipment receives the user's adjustment instruction and adjusts the value of the total number of times it can be used, if the cumulative number of times the dispenser box is pulled reaches the adjusted S', the alarm condition of S2 = 0 is triggered. , the washing equipment sends an alarm signal, and then the value of the total number of uses can be automatically restored to the default value S, such as 20 times in this embodiment.

The operation of the user independently setting the total number of times of use generally occurs when the washing equipment alarms but the user does not clean the recovery device 500. When the washing equipment sends an alarm signal again, because the user did not perform cleaning operations during the previous alarm, the recovery device 500 500 There is a high probability that it has reached, or at least is close to, the state of being blocked by filter impurities. Therefore, when this alarm occurs, the user is likely to manually clean the recovery device 500 .

When the recovery device 500 is used again after cleaning, since no filtered impurities are collected, the total number of washing procedures is accumulated again, that is, before the cumulative number of uses of the recovery device 500 reaches the preset total number of times S, The recovery device 500 will basically not suffer from clogging failure. In this embodiment, the value of the total number of times of use is automatically controlled to be restored to the preset value S, which saves the user the trouble of manual settings and prevents the washing equipment from being washed when the recycling device 500 can continue to be used multiple times. Problem with calling the police.

In the preferred solution of this embodiment, after the washing equipment detects that the dispenser box is pulled out and sends an alarm signal based on the adjusted total usable times value S', before receiving the instruction to start the washing program, if no If the adjustment command for the total number of times can be used, the value of the total number of times can be restored to the default value S, otherwise the value of the total number of times can be determined according to the adjustment command received.

After the washing equipment issues an alarm based on the adjusted value S' of the total number of times it can be used, there may also be special circumstances such as the value S' previously set by the user being inappropriate, resulting in the current recovery device 500 still being able to send the alarm to the user without cleaning. continue to use. In the above solution, when the above situation occurs, the user can continue to manually set the value of the total number of times that can be used. If the user starts the washing program without manually setting the value of the total number of times it can be used, it means that the user has cleaned the recovery device 500, and the washing equipment automatically controls the value of the total number of times it can be used to return to the default value S. .

In this embodiment, the washing equipment presets the total number of times the recovery device 500 can be used, and the number of times the recovery device 500 is pulled out along with the dispenser box of the detergent dispensing device is accumulated as the number of times the recovery device 500 has been used. When the number of uses reaches the preset number of uses, the washing equipment will send out an alarm signal to remind the user to clean the recovery device 500 to ensure that when the washing equipment runs the washing program, the recovery device 500 has sufficient capacity to receive the discharge from the filter device 600 of sewage and collect filtered impurities.

Embodiment 6

As shown in Figures 1 and 2, this embodiment provides another control method for the washing equipment described in Embodiment 1, including:

Get the current filtering capability of the filter module;

It is judged that the current filtration capacity of the filtration module is lower than the filtration threshold, and the control stops transferring water to the filtration module.

Specifically, in this embodiment, when the current filtering capability of the filtering module is lower than the filtering threshold, it means that the filtering capability of the filtering module is close to exhaustion.

As the filtering module continues to work to achieve the filtering function, its filtering capacity will generally gradually decrease. In the above scheme, the washing equipment judges the filtration capacity of the filtration module during the operation of the washing program. When the filtration capacity drops to a certain level, the filtration module is controlled to stop working to avoid continuing after the filtration capacity of the filtration module is exhausted. The work caused the washing equipment to malfunction.

In this embodiment, the filtration capacity of the filtration module specifically includes: the smoothness of the water outlet of the filtration device 600, and/or the remaining capacity of the recovery device 500. Exhaustion of the filtration capacity specifically corresponds to poor water flow from the filter device 600, that is, the filter device 600 is clogged, and/or the recovery device 500 is filled with sewage.

It should be noted that the smoothness of the water outlet may be the smoothness of the filtering device 600 filtering water and outputting filtered water, or the smoothness of the filtering device 600 discharging sewage to the outside.

When the filter device 600 is clogged, the circulation pump 400 continues to work to transport the water in the water tank 100 to the filter device 600, and the filter device 600 cannot drain water to the outside. If the circulation pump 400 continues to work when the filter device 600 is clogged, there is a risk that the circulation pump 400 may be damaged, or the water pressure in the circulation pipeline 220 may be easily damaged due to excessive water pressure.

When the washing equipment is running the washing program, it will intermittently control the filter device 600 to perform self-cleaning and discharge sewage to the recovery device 500, thereby preventing a large amount of filter impurities from accumulating in the filter device 600 and affecting the filtration efficiency. The amount of sewage received in the recovery device 500 gradually increases during the washing process, and the remaining capacity gradually decreases. If the recovery device 500 is filled with sewage, continuing to discharge sewage into it will cause the recovery device 500 to overflow, causing users to complain.

In this embodiment, when it is determined that the current filtering capacity of the filtering module is lower than the filtering threshold, that is, when the filtering capacity is close to exhaustion, the filtering module is controlled to stop working in a timely manner, thereby avoiding the occurrence of the above problems.

Specifically, stopping the water supply to the filter module includes: when the switching device 270 guides the filtered water outlet 6102 of the filter device 600 and the return water pipeline 230, the circulation pump 400 continues to run, and during the process of circulating filtering through the filter device 600, if it is determined If the filter device 600 is clogged, the circulation pump 400 is controlled to stop running.

Alternatively, stopping water transfer to the filter module also includes: if during the process of the filtering device 600 discharging sewage to the recovery device 500, it is determined that the recovery device 500 is filled with sewage, closing the sewage control valve 241; and if the current circulation pump 400 is in a running state , flush the filter device 600 and then discharge the sewage. When it is determined that the recovery device 500 is filled with sewage, the circulation pump 400 also needs to be controlled to stop running.

In a further solution of this embodiment, after the water supply to the filter module is stopped, the washing program remains running. That is to say, when the filtration capacity of the filter module is judged to be too low, only the filter module is controlled to stop working, and the washing program continues to run until the end.

In this way, various problems that may arise from continued filtration are avoided, and the laundry process can be completed without the user's operation, resulting in a higher degree of automation. Especially when the user is not waiting by the washing equipment, the washing program will not be stopped because the filtration capacity of the filter module is exhausted, thus avoiding user complaints caused by the inability to complete the washing program.

Further, stopping water transfer to the filter module also includes: if it is determined that the filtration capacity of the filter module is lower than the filtration threshold when the circulation pump 400 is in a closed state, for example, during the sewage discharge process of the filter device 600, during the subsequent operation of the washing program , the circulation pump 400 is no longer turned on for circulation filtration, but the circulation pump 400 is only turned on during the drainage stage for drainage filtration.

In the washing equipment of this embodiment, the drainage water flow can only be discharged after passing through the filtering device 600, so it is inevitable to perform drainage filtration during the drainage stage.

In order to ensure that the filter module can also implement the drainage filtering function, the filter threshold is set in this embodiment to meet the following requirements: when the current filtering capacity of the filtering module is lower than the filtering threshold, the filtering capacity is close to exhaustion but not completely exhausted. For example, at this time, the filtering device 600 is blocked to a certain extent, and the flow rate of discharged filtered water is slow, but the filtered water can still be discharged through the filtered water outlet 6102 . Alternatively, the recovery device 500 has a smaller remaining capacity, but can still receive a small amount of sewage without overflowing.

In this case, the washing equipment no longer performs cyclic filtration to avoid further clogging the filter device 600 or discharging sewage into the recovery device 500 multiple times during the cyclic filtration process, causing the recovery device 500 to be filled. When the operation reaches the drainage stage, the circulation pump 400 is turned on to perform the drainage process. Filter, the drainage water flow can pass through the filter device 600 without being unable to be discharged, and when sewage needs to be discharged, the recovery device 500 will not overflow.

In a further solution of this embodiment, if the washing equipment obtains the current filtration capacity of the filtration module and determines that the filtration capacity is greater than or equal to the filtration threshold, it will continue to run the washing program and maintain the operating state of conducting water to the filtration module.

Specifically, the control method of the washing equipment in this embodiment is shown in Figure 12, including the following steps:

S41. Run the washing program;

S42. Execute the filtration function and conduct water to the filtration module for filtration;

S43. Determine whether the filtering capacity of the filtering module is exhausted;

S44. If the filtering capability is exhausted, stop executing the filtering function, otherwise continue to execute the filtering function;

S45. The washing program continues to run.

As a preferred solution of this embodiment, when it is determined that the current filtering capability of the filtering module is greater than or equal to the filtering threshold, after the preset detection time has elapsed, the current filtering capability of the filtering module is obtained again, and based on the comparison between the filtering capability and the filtering threshold The result determines whether to stop delivering water to the filter module.

Specifically, when it is determined that the filtration capacity is lower than the filtration threshold, while the washing program continues to run, the filtration capacity of the filter module is no longer obtained until the washing program completes the operation, and this control process ends.

If it is determined that the filtering capability is greater than or equal to the filtering threshold, the filtering capability will be obtained again after the preset detection time to determine whether it is exhausted. The above process is repeated until the filtration capacity drops below the filtration threshold, the control filtration module stops working, or the washing program completes the operation.

In the above scheme, if the filter module is in working state during the operation of the washing program, the filtering capacity of the filtering module is obtained every time the preset detection time passes, and it is judged whether the filtering capacity is lower than the filtering threshold, and when the filtering capacity drops to the filtering threshold, When the value is below the threshold, the filtering module is immediately controlled to stop working. The acquisition and judgment of the filtration capacity is not performed only once. In this way, when the filtration capacity of the filtration module is exhausted in any process of the washing program, the filtration can be stopped as soon as possible, ensuring the smooth operation of the washing program.

As another preferred solution of this embodiment, the washing equipment continuously obtains the filtration capacity of the filtration module during the operation of the filtration module. If it is determined that the current filtration capacity of the filtration module is lower than the filtration threshold, it will stop transferring water to the filtration module, otherwise it will remain The operating status of water transfer to the filter module.

In the above solution, the washing equipment monitors the filtration capacity of the filtration module in real time. Once the filtration capacity is exhausted, filtration will be stopped, ensuring that the washing process can be completed smoothly.

In a further solution of this embodiment, during the operation of the filtration module, the washing equipment determines the current filtration capacity of the filtration module by detecting the water level information in the recovery device 500 .

As a specific solution of this embodiment, the washing equipment detects the water level in the recovery device 500. If the water level reaches the overflow level, it is determined that the current filtration capacity of the filtration module is lower than the filtration threshold.

The water level in the recovery device 500 directly reflects the amount of sewage received in the recovery device 500. By detecting the water level in the recovery device 500, the remaining capacity in the recovery device 500 can be determined. When the water level in the recovery device 500 reaches the overflow level, it means that the recovery device 500 is almost full. At this time, if sewage is discharged into the recovery device 500, the recovery device 500 will soon overflow.

During the operation of the washing program of the washing equipment, if it is detected that the water level in the recovery device 500 reaches the overflow level, it will be judged that the filtering capacity of the filter module is basically exhausted, that is, the sewage in the filter device 600 will be controlled to stop being discharged into the recovery device 500 . Preferably, water will not be directed to the filter device 600 for filtration during subsequent washing procedures to avoid clogging caused by the filter device 600 being unable to perform self-cleaning and sewage discharge.

The specific structure of the recovery device 500 in this embodiment is the same as that in the first embodiment, including a housing 510 and a lint collection assembly 570 disposed inside the housing 510 .

Under normal circumstances, the sewage entering the recovery device 500 will soon be filtered by the lint collection assembly 570 and enter the lower second chamber 532, and the amount of sewage in the first chamber 531 will hardly contain water. The overflow water level is higher than the installation height of the lint collection assembly 570. When it is detected that the water level in the recovery device 500 reaches the overflow level, it is most likely that the lint collection assembly 570 is covered by filtered impurities and is blocked, resulting in sewage. There is no way to enter the second chamber 532.

At this time, if sewage is discharged into the recovery device 500, it will also cause the recovery device 500 to overflow. Therefore, when the water in the recovery device 500 is detected, When the water level reaches the overflow level, it is judged that the filtering capacity is basically exhausted, and the sewage in the filtering device 600 is controlled to stop being discharged into the recovery device 500 . Preferably, during the subsequent operation of the washing program, water is no longer directed to the filtering device 600 for filtration.

As another specific solution of this embodiment, the washing equipment detects the water level change rate in the recovery device during the process of the filtering device 600 discharging sewage into the recovery device 500. If the water level change rate is lower than the preset change rate, it is judged The current filtering capability of the filtering module is lower than the filtering threshold.

After the filter device 600 performs self-cleaning, the cleaned filter impurities are discharged from the sewage outlet 6103 and enter the recovery device 500 along the sewage pipeline 240 . The faster the flow rate of sewage discharge, the greater the sewage flow rate, which is reflected in the change in water level height of the recovery device 500, that is, the higher the water level change rate. If the filtering device 600 is clogged due to the accumulation of filtered impurities, the flow rate of sewage discharge will be reduced, and the water level change rate will be reduced.

When the detected water level change rate is lower than the preset change rate, for example, when it drops to close to zero, it is determined that the current filtering capacity of the filtering module is lower than the filtering threshold, that is, the filtering capacity is basically exhausted. That is to say, when the filtering device 600 performs the sewage discharge operation and discharges sewage into the recovery device 500, the discharged sewage flow is very small, or almost no sewage is discharged, indicating that the current filtering device 600 is almost completely blocked, and it is difficult to further discharge the sewage, and thus It is impossible to achieve effective filtering function. In this case, the washing equipment will no longer conduct water to the filtering device 600 for filtration during subsequent operations of the washing program.

Or, when the water level change rate detected by the washing equipment is the water level change rate in the second chamber 532 of the recovery device 500, during the process of the filter device 600 performing the sewage discharge operation, the sewage continues to enter the recovery device 500 and is collected by the lint. After filtering, the component 570 enters the second chamber 532, causing the water level in the second chamber 532 to continue to increase at a certain water level change rate. However, if the lint collection assembly 570 is clogged, causing sewage to be unable to enter the second chamber 532, the detected water level change rate will significantly decrease, or even decrease to close to zero.

When it is detected that the water level change rate in the second chamber 532 is lower than the preset change rate, it means that the sewage entering the recovery device 500 almost no longer enters the second chamber 532 and the lint collection assembly 570 has been covered by filtered impurities. clogged. At this time, if sewage is discharged into the recovery device 500, the first chamber 531 of the recovery device 500 will soon overflow, which is equivalent to the filtration capacity of the filtration module being basically exhausted. In this case, the sewage in the filtering device 600 is controlled to stop being discharged into the recovery device 500. Preferably, during the subsequent operation of the washing program, water is no longer directed to the filtering device 600 for filtration.

A specific structure of the water level detection device 580 in this embodiment is shown in FIG. 3 , including a step structure 582 and multiple sets of water level probes 581 arranged on the step structure 582 . According to the on-off status of each set of water level probes 581, the current water level in the recovery device 500 can be determined. For example, the overflow water level is set to the height of the step surface corresponding to the highest set of water level probes 581. When a signal that the highest set of water level probes 581 is turned on is received, it is judged that the filtration capacity of the filter module is basically basic. exhausted.

Using the water level detection device 580 with the above structure, the water level in the recovery device 500 continues to rise, so that each group of water level probes 581 is turned on one by one to obtain the time when each group of water level probes 581 is turned on, and then The water level change rate is calculated based on the time difference between different water level probes 581 being turned on.

Or, after any set of water level probes 581 is turned on, and after a set time has elapsed, the adjacent and higher set of water level probes 581 has not been turned on, then it is determined that the current water level change rate is too low. The filtering capacity of the filter module is basically exhausted. For example, when a set of water level probes 581 is turned on and after a set time, a set of water level probes 581 on the adjacent higher step surface is still disconnected, it is judged that the filtration capacity of the filter module is basically exhausted. All.

Another specific structure of the water level detection device 580 is shown in Figure 4, which is an electrode type water level detection device 583. As the water level in the recovery device 500 changes, the capacitance value between the two electrode sheets can change. According to The detected capacitance value can be used to calculate the water level in the recovery device 500 .

Using the water level detection device 580 with the above structure, on the one hand, the specific water level in the recovery device 500 can be obtained in real time, and it can be determined whether the current water level reaches the overflow level. On the other hand, the water level change rate can also be calculated based on the detected real-time changes in water level height, and whether the filtration capacity of the filtration module is basically exhausted is judged based on whether the water level change rate is close to zero. In this way, the water level detection in the recovery device 500 is more accurate.

Another specific structure of the filter module in this embodiment is shown in FIG. 5 , which shows a top structural view of the recovery device 500 . The lint collection assembly 570 is a filter structure that surrounds a collection cavity. The sewage discharged from the filter device 600 directly enters the inside of the collection cavity enclosed by the lint collection assembly 570. After being filtered by the lint collection assembly 570, it enters the inside of the housing 510 and is located on the lint. The space outside the chip collection assembly 570 is used to filter impurities and collect them in the collection cavity. The water level detection device 580 is disposed inside the side wall of the housing 510 to detect the water level information in the recovery device 500 .

Specifically, the water level detection device 580 can detect the water level in the space outside the wire scrap collection assembly 570 in the recovery device 500. According to the detection, The measured water level height determines the remaining capacity in the recovery device 500, and then determines whether the filtration capacity of the filtration module is lower than the filtration threshold.

The water level detection device 580 can also detect the water level change rate in the recovery device 500. When the detected water level change rate is lower than the preset change rate, it means that the lint collection assembly 570 is blocked, causing the received sewage to be unable to be filtered and flow to the line. The outside of the chip collection assembly 570 or the filter device 600 is clogged, causing the sewage to be unable to be smoothly discharged into the recovery device 500. Both of the above situations reflect the decline in the filtering capacity of the filter module.

In this embodiment, the washing equipment acquires the filtration capacity of the filtration module while the washing program is running and the filtration module is working for filtration. When the filtration capacity of the filtration module drops below the filtration threshold, the filtration module can be controlled to stop working in time. However, Continue the wash program without filtering. It not only avoids various problems that may be caused by the filter module working when the filtration capacity is exhausted, but also ensures that the washing program can be completed without user intervention, improving the automation of the washing equipment.

Embodiment 7

As shown in Figures 1 and 7, the difference between this embodiment and the above-described sixth embodiment is that during the operation of the filter module, the washing equipment determines the current filtering capacity of the filter module by detecting the flow information of the sewage discharged from the filter device 600.

Specifically, the flow information is the flow rate of sewage discharged from the filtering device 600 . The washing equipment detects the sewage flow when the filtering device 600 discharges sewage into the recovery device 500. When the detected sewage flow is lower than the preset flow, it is determined that the current filtering capacity of the filter module is lower than the filtering threshold.

Furthermore, in this embodiment, the value of the preset flow rate is very small. When the detected sewage flow rate is lower than the preset flow rate, the sewage flow rate is close to zero, that is, the filtering capacity is basically exhausted.

In this embodiment, the decrease in sewage flow rate is mainly caused by the following two reasons.

When the washing equipment detects that the sewage flow rate drops below the preset flow rate, it means that the filtering device 600 is seriously blocked and cannot discharge sewage, that is, the filtration capacity of the filtration module is basically exhausted. During the subsequent operation of the washing program, water is no longer directed to the filtering device 600 for filtration.

The second reason is that the lint collection component 570 in the recovery device 500 is covered with filter impurities and is blocked, making it impossible to filter the received sewage. The sewage cannot enter the second chamber 532 through the lint collection assembly 570 and will gradually fill the first chamber 531 . When the recovery chamber inside the recovery device 500 has a relatively sealed structure, when the first chamber 531 is filled or nearly full with sewage, the resistance encountered by subsequent sewage when entering the recovery device 500 becomes greater. If the filtering device 600 does not use additional driving force in the process of discharging sewage to the recovery device 500, but only relies on the gravity of the sewage itself to complete the sewage discharging operation, it will be difficult for the sewage to enter the recovery device 500, resulting in a decrease in the sewage flow rate.

When the washing equipment detects that the sewage flow rate drops below the preset flow rate, it means that the sewage currently discharged by the filtering device 600 is difficult to re-enter the recovery device 500, that is, the filtering capacity is basically exhausted. At this time, the sewage in the filtering device 600 is controlled to stop being discharged into the recovery device 500. During the subsequent operation of the washing program, it is preferred that water is no longer directed to the filtering device 600 for filtration.

In order to detect the sewage flow, the washing equipment of this embodiment is provided with a flow meter 243 on the sewage pipeline 240. The flow meter 243 is specifically arranged upstream of the sewage control valve 241 and can detect the sewage flow in the sewage pipeline 240, and then Determine the current filtering capability of the filter module.

In this embodiment, the washing equipment determines the filtration capability of the filtration module by detecting the flow rate of sewage discharge. On the one hand, the sewage flow rate reflects whether the sewage discharge of the filtering device 600 itself is smooth; on the other hand, it also reflects whether the lint collection assembly 570 in the recovery device 500 is clogged. When the filtering device 600 itself is clogged, and the lint collection component 570 in the recycling device 500 is clogged, the filtering device 600 cannot discharge sewage to the recycling device 500, that is, the filtering device 600 cannot clean the accumulated filter impurities in time, and thus Filtering functionality can no longer be implemented. During the running of the washing program, once the above situation is detected, it will be controlled to no longer filter in the subsequent process of this washing program, ensuring that the washing program can be completed smoothly without damaging the filter module.

Embodiment 8

As shown in Figures 1 and 11, the difference between this embodiment and the above-mentioned Embodiment 6 is that the current filtering capability of the filtering module includes the remaining runnable time of the filtering module, and the filtering threshold is a time duration threshold.

Specifically, the washing equipment presets the total operating time of the filter module, and accumulates the operating time of the filter module during the operation of the washing program. Calculate the difference between the total runnable time and the run time to obtain the remaining runnable time of the filter module. When the remaining runnable time is less than the time threshold, the water transfer to the filter module is stopped.

In the above solution, the filter module of the washing equipment, especially the filter device 600 therein, will gradually be filled with filtered impurities as the total duration of filtering increases. Although the filter device 600 can perform self-cleaning during the washing process, there may be some filter impurities attached to it. It is very strong and difficult to clean. According to the volume of the filtering device 600 and the area that can be filtered, the total operating time of the filtering device 600 can be estimated. When the filtering device 600 reaches the total operating time, the filtering effect will be significantly reduced, and the filtering function may even be unable to be realized. .

In this embodiment, during the washing process of the washing equipment, the running time of the filter module, or the filtering device 600, is accumulated to calculate its remaining runnable time. The value of the duration threshold can be very short, such as half a minute to two minutes. When the calculated remaining runnable duration is less than the duration threshold, the filtering effect of the filtering device 600 drops significantly, and the control stops transferring water to the filter module.

In this embodiment, the running time of the filtering device 600 can be accumulated based on the duration that the circulation pump 400 is in the running state and the return water control valve 231 is in the open state.

In this embodiment, by comparing the time duration threshold with the remaining operating time of the filter module, the filter module is controlled to stop working in time during the washing process to prevent the filter module from still being directed to the filter module when it is no longer able to achieve the filtering function. Various problems that water can cause. Compared with the aforementioned first and second embodiments, there is no need to monitor the status of the filtering device 600 or the recovery device 500 in real time, which is easier to implement.

Embodiment 9

As shown in Figures 1 and 11, the difference between this embodiment and the above-mentioned Embodiment 8 is that the current filtering capability of the filtering module includes the remaining runnable times of the filtering module, and the filtering threshold is the times threshold.

Specifically, the washing equipment presets the total number of times the filter module can be run, and accumulates the number of times the filter module has been run during the running of the washing program. Calculate the difference between the total number of operable times and the number of operations that have been performed to obtain the remaining operable times of the filter module. When the remaining operable times are less than the frequency threshold, the water transfer to the filter module is stopped.

In this embodiment, the number of times refers to the number of times the filtering device 600 discharges sewage into the recovery device 500, that is, the number of times the sewage discharge operation is performed. According to the volume of the recovery device 500 and the total amount of sewage that can be discharged into the recovery device 500 by the filtering device 600 for one blowdown operation, the number of blowdown operations required for the recovery device 500 to be filled can be calculated as the operable total of the filter module. frequency.

During the operation of the washing program, after the filtering device 600 continues to filter for a period of time, it performs a sewage discharge operation to discharge the accumulated filtered impurities with the sewage. The washing equipment accumulates the number of times the filtering device 600 performs the sewage discharge operation to obtain the number of times it has been run, and subtracts the number of times it can be run to obtain the remaining number of times it can be run. The number threshold can be, for example, 1 or 2. When the calculated remaining operable times are less than the number threshold, it means that the recovery device 500 is close to being filled with sewage. If the sewage discharge operation continues, there is a risk of the recovery device 500 overflowing.

Since the sewage discharge operation can no longer be performed and the filtered impurities accumulated in the filter device 600 are discharged into the recovery device 500, the filtering effect of the filter device 600 will rapidly decrease and the ideal filtering function cannot be achieved. Therefore, when the calculated remaining number of runs is less than the number threshold, the filter module will no longer work during subsequent washing program operations, that is, it will no longer conduct water to the filter device 600 for filtration.

In this embodiment, by setting a frequency threshold and comparing it with the remaining operating times of the filter module, the filter module is controlled to stop working in time during the washing process to prevent the filter module from still being directed to the filter module when it is no longer able to achieve the filtering function. Various problems that water can cause. Similar to the above-mentioned third embodiment, there is also no need to monitor the status of the filtering device 600 or the recovery device 500 in real time. At the same time, the accumulation of the number of times the blowdown operation is performed can be obtained by counting the number of times the blowdown control valve 241 is opened, which is easy to implement.

Embodiment 10

This embodiment is a further limitation of the above-mentioned Embodiment 6. A control valve 251 is connected to the circulation pipeline 220 between the water outlet end of the circulation pump 400 and the water inlet 6101 of the filter device 600. The control valve 251 communicates with the discharge pipeline 250. Direct connection.

In this embodiment, under normal circumstances, the control valve 251 is in a closed state, and there is no direct connection between the circulation pipeline 220 and the discharge pipeline 250. After the water tank 100 is driven by the circulation pump 400, it enters the filtering device 600 for filtration. Then it is discharged through the external discharge pipe 250. However, when the filter device 600 is completely clogged, the control valve 251 can be opened, and the water in the water tank 100 can be directly passed through the control valve 251 along the circulation pipeline 220 into the external discharge pipeline 250, and then discharged from the washing equipment.

In this embodiment, through the setting of the control valve 251, even if the filtration capacity of the filtration module is completely exhausted, that is, the filtration device 600 is completely blocked and cannot discharge the filtered water, the washing equipment can still realize the drainage function, ensuring that the washing process can be completed smoothly.

Embodiment 11

As shown in Figure 1, the difference between this embodiment and the above-mentioned Embodiment 6 is that when it is determined that the current filtration capacity of the filtration module is lower than the filtration threshold, the frequency and/or duration of water transfer to the filtration module is reduced. This is equivalent to reducing the total running time of the filter module in this washing program.

In this embodiment, the filtering threshold is set to meet the following requirements: when the filtering capacity of the filtering module drops to the filtering threshold, the filtering device 600 can still continue to filter, and the recovery device 500 can still receive a certain amount of sewage, but cannot continue to filter until This washing program is completed.

In this embodiment, reducing the frequency and/or duration of water conduction to the filter module specifically includes: reducing the number of steps in the washing process/rinsing process. During the phase, the length of time the filtering module continues to work.

Specifically, when the filtration capacity of the filtration module is greater than the filtration threshold, in the washing phase with a total running time of T1, the total time for the filtration module to perform cyclic filtration is n1×T1 (0<n1<1). If it is determined that the current filtration capacity of the filtration module is lower than the filtration threshold, the total duration of cyclic filtration of the filtration module in the washing phase is adjusted to n2×T1, where 0<n2<n1.

For example, the running washing program includes a 20-minute washing phase, and the total time for the filtration module to perform cyclic filtration in the washing phase is 15 minutes. When it is judged that the current filtration capacity of the filtration module is lower than the filtration threshold, the total time for cyclic filtration in the washing phase is The duration is adjusted to 5 minutes.

The rinsing stage is similar to the washing stage. The total running time of the rinsing stage is T2, and the original total time of the filter module for circulating filtration is n3×T2 (0＜n3＜1). If it is judged that the current filtering capacity of the filter module is lower than the filter threshold, the total duration of the filter module's cyclic filtering during the rinse stage is adjusted to n4×T2, where 0<n4<n3.

In this embodiment, when the washing equipment determines that the filtration capacity of the filtration module has dropped below the filtration threshold, the total time for the filtration module to perform cyclic filtration is reduced, thereby preventing the filtration capacity of the filtration module from being completely exhausted before the washing program is completed. The washing equipment can successfully complete the washing program.

Embodiment 12

As shown in Figure 1, the difference between this embodiment and the eleventh embodiment is that when it is determined that the current filtering capacity of the filter module is lower than the filter threshold, the frequency of water transfer to the filter module is reduced, wherein the frequency of water transfer to the filter module is reduced. Frequency means that no circulating filtration is performed during the washing stage, and only circulating filtration is performed during the rinsing stage.

During the washing stage, the washing equipment rotates the water tank 100 to drive the clothes to tumble and cause friction with other clothes or the inner wall of the water tank 100. The clothes are fully rubbed to wash away stains on the clothes. The washing force is relatively large, thereby generating an amount of lint falling off the clothes. Bigger too. In the rinsing stage, the main purpose is to remove the detergent attached to the clothes. The washing intensity is relatively small, and most of the lint has been removed in the washing stage, so the amount of lint that needs to be filtered out is small.

When the washing equipment determines that the current filtration capacity of the filtration module is lower than the filtration threshold during the washing phase, it stops continuing to perform cyclic filtration, and restarts the circulation pump 400 during the washing and drainage phase to filter the drainage in the washing phase. Then in the rinsing stage, the circulation pump 400 is turned on to perform circulation filtration to ensure that the lint in the water is fully filtered out in the rinsing stage.

Since a large amount of lint is generally produced during the washing stage, circulation filtration is not performed during the washing stage, and drainage filtration is only performed once during drainage. This can avoid clogging of the filter device 600 caused by continuous circulation of washing water, or the need to receive a large amount of sewage in the recovery device 500. Overflow occurs. However, the lint content in the water during the rinsing stage is less, and the current filtration capacity of the filter module can complete the cyclic filtration during the rinsing stage without clogging.

In this embodiment, when the washing equipment determines that the filtration capacity of the filtration module has dropped below the filtration threshold, cyclic filtration will no longer be performed in the washing phase, and cyclic filtration will be performed in the rinsing phase. This can avoid the filter module consuming a large amount of filtration capacity in the washing phase. This prevents its filtration capacity from being completely exhausted before the washing program is completed, so that the washing equipment can successfully complete the washing program.

Embodiment 13

As shown in Figure 1, the difference between this embodiment and the above-mentioned Embodiment 11 is that the filter module will perform the residual water discharge operation multiple times during the washing program. The reduction of the frequency of water transfer to the filter module means to reduce the frequency of water transfer to the filter module. The number of execution times for draining residual water. The operation of discharging residual water refers to the filtering device 600 discharging sewage to the recovery device 500 when the circulation pump 400 is running.

In this embodiment, no additional power mechanism is provided in the process of discharging sewage from the filtering device 600 to the recovery device 500. If the sewage is discharged only by gravity, there may be residual sewage in the filtering device 600. For this reason, after the filtering device 600 continues filtering for a period of time, the sewage control valve 241 will be opened while the circulation pump 400 is running, and the driving force provided by the circulation pump 400 will be used to discharge sewage into the recovery device 500 to improve the efficiency of filtering impurities. degree.

Specifically, when the washing equipment is running a washing program, every time the filtering device 600 continues filtering for a period of time, the circulation pump 400 is turned off and the discharge control valve 241 is opened, and the filtered impurities accumulated in the filtering device 600 are discharged into the recovery device 500 along with the water flow. After the sewage discharge is completed, the sewage control valve 241 can be closed and the circulation pump 400 can be turned on again to allow the filtering device 600 to continue filtering. After several consecutive sewage discharges, the washing equipment controls the sewage control valve 241 to open while the circulation pump 400 is running, and performs a residual water discharge operation to more fully discharge the filtered impurities accumulated in the filter device 600.

It can be understood that in one residual water discharge operation, the amount of sewage discharged is generally greater than the amount of sewage discharged when the sewage control valve 241 is opened alone and the sewage is discharged into the recovery device 500 by gravity alone.

In this embodiment, when it is determined that the current filtration capacity of the filtration module is lower than the filtration threshold, the number of execution times of the residual water discharge operation is reduced, that is, In order to reduce the total amount of sewage discharged into the recovery device 500 during subsequent washing procedures. Especially when the recovery device 500 is clogged to a certain extent, or the remaining capacity in the recovery device 500 is small, it can be ensured that the washing equipment completes the washing process without the recovery device 500 overflowing.

In the preferred solution of this embodiment, during one washing program operation, the residual water discharge operation is set to be performed a total of N times, where N is a positive integer greater than or equal to 2. When it is judged that the current filtration capacity of the filtration module is lower than the filtration threshold, the washing equipment skips several intermediate residual water discharge operations in subsequent washing program runs and does not perform them, and only performs the last residual water discharge operation.

Further, when the washing equipment determines that the current filtration capacity of the filter module is lower than the filtration threshold, the washing equipment will no longer perform the residual water draining operation in subsequent washing program operations until the washing program reaches the drainage process of the last rinsing stage. The washing equipment only performs a residual water discharge operation of the filter module before the last rinse and drainage starts or during the drainage process, thereby controlling the total amount of sewage discharged into the recovery device 500 in this washing program and avoiding overflow failure of the recovery device 500 .

For example, during a washing program, the residual water draining operation is set to be performed a total of five times. When the washing program determines that the current filtration capacity of the filter module is lower than the filtration threshold during the running of the washing program, the residual water discharge operation will no longer be performed during subsequent operations until the last rinse and drainage operation is performed, and the final residual water discharge operation will be performed. .

In this embodiment, when the filtration capacity of the filtration module is lower than the filtration threshold, especially when the recovery device 500 is clogged to a certain extent, or the recovery device 500 has received a large amount of sewage and has less remaining capacity, the washing equipment passes the By skipping several intermediate residual water discharge operations and only performing the last residual water discharge operation in the washing program, the total amount of sewage discharged by the filter device 600 into the recovery device 500 is reduced. This ensures that the filtration module can successfully complete the washing program before the filtration capacity is completely exhausted.

Embodiment 14

As shown in Figures 1 and 11, this embodiment provides another control method for the washing equipment described in the first embodiment, including: determining that the installation of the filter module meets the set conditions, and the washing equipment runs a washing program.

Correspondingly, the washing equipment also includes a detection device for detecting whether the installation of the filter module meets the set conditions. The control system of the washing equipment can receive the detection results of the detection device and control the washing equipment to run the washing program when the installation of the filter module meets the set conditions.

Specifically, the filter device 600 in this embodiment is detachably installed in the washing equipment. After the filtering device 600 has been working for a certain period of time, a certain amount of filtering impurities will accumulate inside the filtering device 600 , which will affect subsequent filtration efficiency. In severe cases, the filtering function may not be realized due to clogging of the filtering device 600 .

At this time, the user can remove the filter device 600 for cleaning, and after the cleaning is completed, reinstall the filter device 600 back to the corresponding position on the washing equipment. If the filter device 600 cannot be cleaned, or the filter device 600 is damaged, the user can also purchase a new filter device 600 and install it on the washing equipment to ensure the operation of the filter function.

Furthermore, in this embodiment, determining that the installation of the filter module satisfies the set conditions means determining that the installation of the filter device 600 satisfies the set conditions.

In one solution of this embodiment, judging that the installation of the filter device 600 meets the set conditions specifically means: judging that the filter device 600 is installed in place in the washing equipment. When the filter device 600 is installed in place, the washing equipment can run a washing program.

Specifically, as shown in Figure 14, the control method includes the following steps:

S51. The washing equipment receives the start command and determines whether the filter device 600 is installed in place;

S52. If the filter device 600 is installed in place, the washing equipment starts running the washing process; if the filtering device 600 is not installed in place, the washing equipment does not run the washing process.

In detail, in step S52, if the filter device 600 is not installed in place, the washing equipment is locked and an alarm signal is issued.

Through the above solution, the washing equipment can independently detect whether the filter device 600 is installed in place before starting to run the washing program, and when the filter device 600 is not installed in place, the washing equipment is locked and the washing program will not be run. In this way, it is avoided that the washing equipment performs laundry when the filter device 600 is not installed in place, causing the filtering function to be unable to be realized, and prevents the failure of the filtering function from affecting the cleaning effect of the clothes, or causing microplastics in the drainage of the washing equipment. The problem of excessive content.

On the other hand, if the filter device 600 is not installed in place, it may also cause water leakage in the water channel structure in the washing equipment at the connection point with the filter device 600 . Detecting the installation status of the filter device 600 before the washing equipment starts filtering can avoid the problem of water leakage when the washing equipment performs filtering when the filter device 600 is not installed in place.

At the same time, when it is detected that the filter device 600 is not installed in place, the washing equipment will also send out an alarm signal to promptly remind the user to check the filter device 600. After the user reinstalls the filter device 600, the washing equipment can operate normally.

In the above solution of this embodiment, the detection device for determining whether the filter device 600 is installed in place can be implemented by an induction detection device. Specifically, the induction detection device includes a detection element and a detected element. The detection element is arranged at the installation position of the filter device 600 in the washing equipment, and the detected element is arranged on the filter device 600 . When the detected element approaches or contacts the detection element, the detection element is triggered to generate a feedback signal, and the washing equipment determines that the filter device 600 has been installed in place.

In detail, the detection element may be a trigger switch, and the detected element may be a trigger part provided on the filtering device 600 . When the filter device 600 is installed in place, the trigger part contacts the trigger switch, and the washing equipment determines that the filter device 600 is installed in place.

Alternatively, the detection element is a magnetic sensitive element, and the detected element is a magnetic piece that can generate a magnetic field. When the filter device 600 is installed in place, the magnetic piece is close to the magnetic sensitive element to a certain extent, thereby triggering the magnetic sensitive element to move toward the washing equipment. The control system sends a feedback signal, and the washing equipment determines that the filter device 600 has been installed in place.

In another solution of this embodiment, determining whether the installation of the filter device 600 meets the set conditions specifically means: determining whether the model of the filter device 600 matches the washing equipment. When the model of the filter device 600 matches the washing equipment, the washing equipment can run the washing program.

Specifically, as shown in Figure 15, the control method includes the following steps:

S61. The washing equipment receives the startup command and determines whether the model of the filtering device 600 matches the washing equipment;

S62. If the models match, the washing equipment starts running the washing program; if the models do not match, the washing equipment does not run the washing process.

In detail, in step S62, if the model of the filter device 600 does not match the washing equipment, the washing equipment is locked and an alarm signal is issued.

Through the above solution, the washing equipment can independently detect whether the model of the filter device 600 matches the washing equipment before starting to run the washing program, and if it cannot match, the washing equipment will be locked and the washing program will not be run. When the user replaces the new filter device 600, on the one hand, it avoids the problem that the user installs a filter device 600 with an incompatible model on the washing equipment, resulting in the filtering function being unable to be realized or the filtering effect being poor. On the other hand, the filter device 600 counterfeited by other merchants cannot be used due to model mismatch. This can ensure that the user is using the genuine filter device 600 sold by the manufacturer, effectively preventing the occurrence of counterfeit filter devices 600 by unscrupulous merchants. At the same time, it also prevents users from using counterfeit and inferior filter devices 600, which affects the filtering effect during the laundry process.

Similar to the previous solution, when the model of the detection filter device 600 cannot match the washing equipment, the washing equipment will also send out an alarm signal to remind the user to check so that the correct filter device 600 can be replaced in time to avoid affecting the normal operation of the washing equipment. run.

In the above solution of this embodiment, in order to determine whether the model of the filter device 600 matches the washing equipment, an identification tag can be set on the filter device 600. At the same time, the washing equipment can set an identification device at the installation position of the filter device 600 as a detection filter device 600. Install a detection device that meets the setting conditions. The identification device can read the identification tag on the filter device 600 and determine whether the model of the filter device 600 matches the washing equipment.

For example, a QR code or barcode is pasted or printed on the outer wall of the filtering device 600, and a scanner is installed at the corresponding position on the washing equipment. The QR code or barcode is scanned by the scanner, and the identity ID of the filtering device 600 is obtained through analysis and determination. Whether the model of the filter device 600 matches the washing equipment.

Alternatively, the filtering device 600 is provided with an electronic tag, such as an RFID tag or an NFC tag, and an identification device that can read the electronic tag is installed at a corresponding position on the washing equipment. The identification device reads the electronic tag and obtains the filtering device stored therein. 600's identity ID to determine whether the model of the filter device 600 matches the washing equipment.

In this embodiment, the above two solutions can also be combined and applied to the washing equipment. That is to say, after receiving the start command, the washing equipment detects whether the filter device 600 is installed in place and whether the model of the filter device 600 matches the washing equipment. Only when the filter device 600 is installed in place and the model matches, the washing equipment further starts to run the set washing program; otherwise, the washing equipment is locked and an alarm signal is issued.

In this embodiment, a program start key is provided on the washing equipment for the user to operate and start the washing program. The washing equipment receiving the start instruction specifically means that the washing equipment receives a signal that the program start key is triggered. When using the washing equipment for laundry, the user sets the washing program to be run. After the setting is completed, the program start button can be triggered. At this time, the washing equipment detects whether the filter device 600 is installed in place and/or whether the model of the filter device 600 matches the washing equipment. When the set conditions are met, the washing program set by the user can be run.

In this embodiment, the washing equipment first detects the installation of the filter device 600 before starting to run the washing program. If the filter device 600 is not installed in place, or the model of the installed filter device 600 does not match the washing equipment, then Lock the washing equipment and send an alarm signal to remind the user. In this way, only when the user correctly installs the filter device 600, the washing equipment can run the washing process normally, ensuring the cleaning effect of the clothes and ensuring that the microplastics generated by the laundry are not directly discharged.

Embodiment 15

As shown in Figures 1 and 11, the difference between this embodiment and the fourteenth embodiment mentioned above is that: judging that the installation of the filter module meets the set conditions means judging that the installation of the recovery device 500 meets the set conditions.

Specifically, the recovery device 500 is detachably installed on the washing equipment. When the sewage in the recovery device 500 reaches a certain amount, the user can remove the recovery device 500 and process the sewage therein. After treating the sewage, the user can reinstall the empty recovery device 500 back into the washing equipment, thereby continuing to receive the sewage discharged by the filtering device 600 when the washing equipment is operated again.

In one solution of this embodiment, determining that the installation of the recovery device 500 meets the set conditions specifically means: determining that the recovery device 500 is installed in place in the washing equipment. When the recovery device 500 is installed in place, the washing equipment can run a washing program.

Specifically, as shown in Figure 16, the control method includes the following steps:

S71. The washing equipment receives the start command and determines whether the recovery device 500 is installed in place;

S72. If the recovery device 500 is installed in place, the washing equipment starts running the washing process; if the recovery device 500 is not installed in place, the washing equipment does not run the washing process.

In detail, in step S72, if the recovery device 500 is not installed in place, the washing equipment is locked and an alarm signal is issued.

Through the above solution, the washing equipment can independently detect whether the recovery device 500 is installed in place before starting to run the washing program, and when the recovery device 500 is not installed in place, the washing equipment is locked and the washing program will not be run. In this way, it is avoided that the washing equipment is operated when the recovery device 500 is not installed in place. During the process of the filtering device 600 discharging sewage, the washing equipment may leak due to water leakage at the outlet end of the sewage pipeline 240, or the sewage may not enter. In the recovery device 500, microplastics in the sewage may be mixed into the drainage water of the washing equipment and discharged.

At the same time, when it is detected that the recovery device 500 is not installed in place, the washing equipment will also send out an alarm signal to promptly remind the user to check the installation of the recovery device 500. After the user reinstalls the recovery device 500, the washing equipment can operate normally.

Specifically, the recovery device 500 in this embodiment is installed on the box 10 of the washing equipment so as to be insertable/extractable. The box 10 is provided with a receiving tank for accommodating the recovery device 500 .

The detection device used to detect whether the installation of the recovery device 500 meets the set conditions is a position detection device provided inside the accommodation tank. The position detection device can detect the relative position of the recovery device 500 in the accommodation tank. If the position detection device is triggered by the recovery device 500, it is determined that the recovery device 500 is installed in place.

In detail, the position detection device is a mechanical switch. When the recovery device 500 is installed in place, the recovery device 500 contacts the mechanical switch and triggers the mechanical switch to send a feedback signal to the control system of the washing equipment, and the washing equipment determines the recovery. Device 500 is installed.

Alternatively, the position detection device is a magnetic sensitive element, and the recovery device 500 is provided with a magnetic component that can generate a magnetic field. When the recovery device 500 is installed in place, the magnetic component on the recovery device 500 is close to the magnetic sensitive component to a certain extent, so that The magnetic sensitive element is triggered to send a feedback signal to the control system of the washing equipment, and the washing equipment determines that the recovery device 500 has been installed in place.

In another solution of this embodiment, determining that the installation of the recovery device 500 meets the set conditions specifically refers to determining whether the model of the recovery device 500 matches the washing equipment. When the model of the recovery device 500 matches the washing equipment, the washing equipment can run the washing program.

Specifically, as shown in Figure 17, the control method includes the following steps:

S81. The washing equipment receives the start command and determines whether the model of the recovery device 500 matches the washing equipment;

S82. If the models match, the washing equipment starts running the washing program; if the models do not match, the washing equipment does not run the washing process.

In detail, in step S82, if the model of the recovery device 500 does not match the washing equipment, the washing equipment is locked and an alarm signal is issued.

The recovery device 500 may be damaged during use, in which case the recovery device 500 needs to be replaced with a new one. When the user replaces the filter device 600 with a new one, if the model of the recovery device 500 does not match, the recovery device 500 and the water outlet end of the sewage pipe 240 may not be connected in a sealed manner, which may cause water leakage in the washing equipment.

The washing equipment automatically detects whether the model of the recovery device 500 matches the washing equipment before starting to run the washing program, and if it cannot match, the washing equipment is locked and the washing program will not be run. When the user replaces the new filter device 600, on the one hand, it avoids the user from installing a recovery device 500 of an unmatched model on the washing equipment, which may lead to malfunction of the sewage receiving function and cause water leakage. On the other hand, the recycling device 500 counterfeited by other merchants cannot be used due to model mismatch. This can ensure that the user is using the genuine recycling device 500 sold by the manufacturer, effectively preventing unscrupulous merchants from counterfeiting the recycling device 500 . At the same time, it also prevents users from using counterfeit and inferior recycling devices 500, which may cause water leakage in washing equipment. Or there is a problem that part of the sewage discharged from the filtering device 600 is directly discharged.

Similar to the previous solution, when the model of the detection recovery device 500 cannot match the washing equipment, the washing equipment will also send out an alarm signal to remind the user to check so that it can be replaced with the correct recovery device 500 in time to avoid affecting the normal operation of the washing equipment. run.

Specifically, in order to detect whether the model of the recovery device 500 matches, an identification portion is provided on the recovery device 500 , and the washing equipment is provided at the installation position of the recovery device 500 , for example, on the inner wall of the accommodation tank for accommodating the recovery device 500 . The identification unit serves as a detection device that detects whether the installation of the recovery device 500 satisfies the set conditions. The identification part recognizes the identification part of the recovery device 500 to determine whether the model of the recovery device 500 matches the washing equipment.

In detail, the identification part is a QR code or barcode pasted or printed on the outer wall of the recycling device 500, and the identification part is a code scanner installed at a corresponding position on the inner wall of the storage tank. Scan the QR code or barcode, analyze and obtain the identity ID of the recycling device 500, and determine whether the model of the recycling device 500 matches the washing equipment.

Alternatively, the identification part is an electronic tag provided on the recycling device 500, such as an RFID tag or an NFC tag, etc., and the identification part is an electronic tag installed at a corresponding position on the inner wall of the storage tank and capable of reading the electronic tag. The reader reads the electronic tag, obtains the identity ID of the recycling device 500 stored therein, and determines whether the model of the recycling device 500 matches the washing equipment.

In this embodiment, the above two solutions can also be combined and applied to the washing equipment. That is to say, after receiving the start command, the washing equipment detects whether the recovery device 500 is installed in place and whether the model of the recovery device 500 matches the washing equipment. Only when the recovery device 500 is installed in place and the model matches, the washing equipment further starts to run the set washing program; otherwise, the washing equipment is locked and an alarm signal is issued.

In this embodiment, the washing equipment first detects the installation of the recovery device 500 before starting to run the washing program. If the recovery device 500 is not installed in place, or the model of the installed recovery device 500 does not match the washing equipment, then Lock the washing equipment and send an alarm signal to remind the user. In this way, only when the user correctly installs the recovery device 500, the washing equipment can run the washing program normally, ensuring that the washing equipment can smoothly realize the sewage receiving function of the filtering device 600.

Embodiment 16

As shown in Figures 1 and 11, this embodiment is a further limitation of the fifteenth embodiment. The recovery device 500 includes a housing 510 and a wire scrap collection assembly 570 disposed inside the housing 510. The component 570 filters the sewage received by the recovery device 500 and collects filtered impurities in the water.

The specific structure of the recovery device 500 including the lint collection assembly 570 has been described in detail in Embodiment 1, and will not be described again here.

The control method of the washing equipment in this embodiment includes: determining that the recovery device 500 is installed in place, and the washing equipment runs a washing program.

In one solution of this embodiment, the installation of the recovery device 500 is similar to the above-mentioned Embodiment 15, which means that the housing 510 of the recovery device 500 is installed in the washing equipment.

In another solution of this embodiment, the installation of the recycling device 500 in place specifically means that the wire scrap collection assembly 570 is installed in the housing 510 of the recycling device 500 . Specifically, a sensing element is provided on the inner wall of the casing 510 as a detection device. When the lint collection assembly 570 is close to or contacts the sensing element, it is determined that the lint collection assembly 570 is installed in place inside the casing 510 .

In detail, the sensing element may be a contact switch. When the lint collection assembly 570 is installed inside the housing 510, it comes into contact with the contact switch, thereby triggering the contact switch to send a feedback signal to the control system of the washing equipment. The device determines that the lint collection assembly 570 has been installed in place.

Alternatively, the sensing element may be a magnetic sensitive element, such as a reed switch, and the wire scrap collecting assembly 570 is provided with a magnetic component that can generate a magnetic field. When the lint collection assembly 570 is installed inside the housing 510, the magnetic sensor senses the magnetic component and sends a feedback signal to the control system of the washing equipment, and the washing equipment determines that the lint collection assembly 570 has been installed in place.

In the above solution, when the washing equipment receives the start command, it is determined whether the lint collection assembly 570 is installed in place according to the detection of the lint collection assembly 570 by the sensing element. When the lint collection assembly 570 is installed in place, the washing equipment will run the set washing program. Otherwise, the washing equipment will be locked and will not run the washing program. At the same time, an alarm signal will be sent to remind the user to check the installation status of the lint collection assembly 570 .

In this embodiment, the washing equipment can detect whether the lint collection assembly 570 is installed in place inside the housing 510 of the recovery device 500 before starting the washing program. If the lint collection assembly 570 is not installed in place, the system will lock the lint collection assembly 570 . Washing equipment sends an alarm signal to remind the user. Especially when the user forgets to reinstall the lint collection assembly 570 and starts the washing program after cleaning the recycling device 500 , it can avoid the washing equipment without installing the lint collection assembly 570 , and further prevent the occurrence of lint collection assembly 570 in the recycling device 500 . The problem of collecting sewage mixed with filtered impurities makes it difficult for users to perform subsequent processing.

Embodiment 17

As shown in Figure 1 and Figure 11, this embodiment is a further limitation of the sixteenth or seventeenth embodiment above. The washing equipment detects the installation status of the filter device 600 and the installation status of the recovery device 500 respectively. When the filter device 600 When the installation of the recovery device 500 meets the set conditions and the installation of the recovery device 500 also meets the set conditions, the washing equipment runs the washing program.

In one solution of this embodiment, after receiving the start command, the washing equipment detects whether the filter device 600 is installed in place and whether the recovery device 500 is installed in place. Only when the filter device 600 and the recovery device 500 are respectively installed in place, the washing equipment further starts to run the set washing program; otherwise, the washing equipment is locked and an alarm signal is issued.

In another solution of this embodiment, after receiving the startup command, the washing equipment separately detects whether the model of the filter device 600 and the model of the recovery device 500 match the washing equipment. Only when the model of the filter device 600 and the recovery device 500 match the washing equipment, the washing equipment further starts to run the set washing program; otherwise, the washing equipment is locked and an alarm signal is issued.

It should be noted that in this embodiment, it is also possible to detect whether the filter device 600 is installed in place and whether the model of the recovery device 500 matches the washing equipment, and then control whether the washing equipment runs a washing program. Alternatively, it can also be detected whether the model of the filtering device 600 matches the washing equipment, and whether the recovery device 500 is installed in place, and then whether the washing equipment runs a washing program can be controlled.

In the optimal solution of this embodiment, when the washing equipment receives the start command, it is detected whether the filter device 600 is installed in place, whether the model of the filter device 600 matches the washing equipment, and whether the recovery device 500 is installed in place. And whether the model of the recovery device 500 matches the washing equipment is tested respectively. Only when the above four conditions are met, the washing equipment will run the washing program, otherwise, the washing equipment will be locked and an alarm signal will be sent.

In this embodiment, the washing equipment detects the installation status of the filter device 600 and the recovery device 500 respectively. If there is a problem with the installation of either of the two, the washing equipment will not run the washing program, ensuring that the This ensures that the washing equipment can operate its filtration and sewage collection functions normally.

Embodiment 18

As shown in Figures 1 and 2, this embodiment provides another control method for the washing equipment described in the first embodiment.

Specifically, the washing equipment has an additional program for conducting water filtration to the filtration module in the washing program. The additional program performed by the washing equipment includes the following operations:

The circulation pump 400 works to guide water to the filtering device 600 for filtering;

And perform the sewage discharge operation of the filtering device 600 to discharge sewage into the recovery device 500 according to the set time sequence.

In this embodiment, the control method of the washing equipment includes:

If the filtration capacity is lower than the preset value, it will prompt that the washing program cannot be run;

If the filtration capacity is greater than or equal to the preset value, the washing equipment starts to run the washing process.

Specifically, the prompt that the washing program cannot be run includes: issuing a prompt message that the washing program cannot be run, and/or the washing equipment does not run the washing program.

In this embodiment, a program start key is provided on the washing equipment for the user to operate and start the washing program. After the user turns on the laundry equipment, he sets the washing program he wants to run. After the setting is completed, he can trigger the program start button to start the set washing program. The washing equipment receives the signal that the program start key is triggered, that is, receives the instruction to start the washing program.

At this time, the washing equipment judges the filtration capacity of the filtration module. If the filtration capacity is sufficient, it can start to run the washing program set by the user, and perform additional programs during the running of the washing program, that is, the filter module is used to realize the filtration function. Ensure the cleaning effect of clothes. If the filtration capacity of the filtration module is not enough to complete the additional program requirements in this washing program, the washing equipment will not run the washing program, which prevents the washing equipment from running the washing program when the filtration capacity of the filtration module is insufficient and the filtering function cannot be realized. The problem.

Specifically, after the user triggers the program start key, if it is determined that the filtration capacity of the filter module is insufficient, the washing equipment will not respond to the instruction to start the washing program, but will remain in a standby state. After the user sees that the washing program has not started, he or she determines that it may be due to insufficient filtration capacity of the filter module. Then the user can check whether the filter module is abnormal and clean, maintain or replace the filter module. After the user completes cleaning, maintenance or replacement of the filter module, the washing process can be restarted.

Furthermore, when the washing equipment determines that the filtration capacity of the filter module is insufficient, in addition to not starting the washing program, it also sends a prompt message to the user. message, such as "Insufficient filtration capacity to run the washing program, please check the filtration module." After receiving the prompt message, the user cleans, maintains or replaces the filter module, and then starts the washing process again. By sending prompt information to the user, the user can check the filter module in a more targeted manner, which avoids the user not knowing why the washing program cannot run and spending a lot of time troubleshooting the cause of the fault.

In a further solution of this embodiment, obtaining the filtration capacity of the filtration module includes: obtaining the current filtration capacity of the filtration module recorded before the end of the washing program before the washing equipment was run.

Specifically, the washing equipment performs an additional program during the running of the washing program, and conducts water to the filter module for filtration. Before the end of the washing program, the current filtration capacity of the filter module is obtained and recorded, which is used to determine whether the washing program can be run based on the recorded filtration capacity when the washing program is started again.

In this embodiment, the filtration capacity of the filtration module specifically includes: the smoothness of the water outlet of the filtration device 600, and/or the remaining capacity of the recovery device 500. In particular, the smoothness of the water outlet of the filtering device 600 can only be detected when the filter module is in working condition.

The washing equipment in this embodiment obtains the current filtration capacity of the filtration module before the end of each washing program and records it. After the washing program is completed, if the instruction to start the washing program is received again, the previously recorded filtration capacity will be directly retrieved to determine whether the washing program can be run. That is to say, after the washing equipment receives the instruction to start the washing program, the filter module does not need to enter the working state, and the washing equipment can judge whether its filtration capacity meets the operation requirements.

Through the above method, when the filtration capacity of the filtration module is obtained before the washing equipment starts the washing program, there is no need to control the filtration module to continue working for a period of time, especially when the filtration capacity of the filtration module has been exhausted during the previous operation. In order to obtain the filtering capability of the filtering module, there is a problem of forcing the filtering module to run when the filtering capability is exhausted.

In this embodiment, the current filtration capacity of the filter module obtained before the end of each washing program includes: the smoothness of the water outlet of the filter device 600 before the end of the washing program, and/or the remaining capacity of the recovery device 500 before the end of the washing program. That is, the filtration capacity of the filtration module is measured by the smoothness of the water outlet of the filtration device 600 and the remaining capacity of the recovery device 500 . It should be noted that the smoothness of the water outlet may be the smoothness of the filtering device 600 filtering water and outputting filtered water, or the smoothness of the filtering device 600 discharging sewage to the outside.

In this embodiment, the setting of the preset value for comparison with the filtering capacity may be the size of the filtering capacity corresponding to when the filtering capacity is close to exhaustion or has been exhausted. That is, when it is determined that the filtering capacity is lower than the preset value, it means that the obtained filtering capacity is that the filtering capacity of the filtering module is close to exhaustion or has been exhausted.

Correspondingly, for the situation where the filtration capacity is greater than the preset value, that is, the "filtration capacity is sufficient" in the above description of this embodiment, it can only mean that the filtration capacity of the filtration module is sufficient to support the startup of the washing program and start executing additional programs, that is, filtration The module starts working for filtration, which does not necessarily mean that the filtration capacity of the filtration module is sufficient. The washing equipment will perform additional procedures during this washing program until the end of the washing program.

The washing equipment obtains the smoothness of the water outlet of the filter device 600 and/or the remaining capacity of the recovery device 500 before the end of each washing program and records it as the filtration capacity of the filter module. When the washing program is started again, if the recorded filtration capacity is retrieved and the filtering capacity is displayed, If the capacity is close to or has been exhausted, the washing program will not be run to avoid the problem of being unable to enter the filtering device 600 when the washing program is started, or the filtering device 600 discharging sewage to the recovery device 500 causing the recovery device 500 to overflow.

In the specific solution of this embodiment, as shown in Figure 18, the control method of the washing equipment includes the following steps:

S91. The washing equipment receives the instruction to start the washing program;

S92. Obtain the current filtration capacity of the filtration module recorded before the end of the previous washing program;

S93. Determine whether the filtering capacity is exhausted;

S94. If yes, the washing program cannot be run. If not, start the washing program.

In a further solution of this embodiment, the washing equipment obtains the water level information in the recovery device 500 before the end of the washing process, and determines the current filtration capacity of the filtration module based on the water level information.

As a specific solution of this embodiment, the washing equipment detects the water level in the recovery device 500 before the washing process ends, and determines the current filtration capacity of the filtration module based on the water level.

The water level in the recovery device 500 directly reflects the amount of sewage received in the recovery device 500. By detecting the water level in the recovery device 500, the remaining capacity in the recovery device 500 can be determined.

In detail, when the detected water level reaches the preset water level, it is determined that the filtering capacity of the filter module is close to or has been exhausted. The preset water level is specifically the overflow water level in the recovery device 500. When the water level in the recovery device 500 reaches the overflow level, it means that the recovery device 500 has reached a nearly full state. If water is discharged into the recovery device 500 again, Entering sewage will soon cause the recovery device 500 to overflow. In this case, when the washing equipment receives the instruction to start the washing program again, the previously recorded filtration capacity is close to or has been exhausted, and the washing program will not be started.

The recovery device 500 includes a housing 510 and a lint collection assembly 570 disposed inside the housing 510 . Under normal circumstances, the sewage entering the recovery device 500 will soon be filtered by the lint collection assembly 570 and enter the lower second chamber 532, and the amount of sewage in the first chamber 531 will hardly contain water. The overflow water level is higher than the installation height of the lint collection assembly 570. When it is detected that the water level in the recovery device 500 exceeds the overflow level, it is most likely that the lint collection assembly 570 is covered by filtered impurities and is blocked, resulting in sewage. There is no way to enter the second chamber 532. At this time, if sewage is discharged into the recovery device 500, it will also cause the recovery device 500 to overflow. Therefore, after receiving the instruction to start the washing program, the filtering capacity recorded last time is close to or exhausted, and the washing program will not run. .

As another specific solution of this embodiment, before the end of the washing process, the washing equipment detects the water level change rate in the recovery device 500 when the filter device 600 discharges sewage into the recovery device 500 for the last time. According to the water level change rate Determine the current filtering capabilities of the filter module.

When the detected water level change rate drops to close to zero, it is determined that the filtration capacity of the filtration module is close to or has been exhausted. At this time, when the filtering device 600 performs the sewage discharge operation, the discharged sewage flow is very small and almost no sewage is discharged. This indicates that the filtering device 600 is almost completely blocked and it is difficult to discharge the sewage, thereby making it impossible to continue filtering. In this case, when the washing equipment receives the instruction to start the washing program again, it will obtain that the previously recorded filtration capacity is close to or has been exhausted, and the washing program will not be started.

When it is detected that the water level change rate in the second chamber 532 drops to close to zero, it means that the sewage entering the recovery device 500 can no longer enter the second chamber 532, and the lint collection assembly 570 has been covered by filtered impurities, causing clogged. At this time, if sewage is discharged into the recovery device 500, the first chamber 531 of the recovery device 500 will soon overflow. Therefore, the filtering capacity of the filter module is close to or exhausted at this time. After the washing equipment receives the instruction to start the washing program again, the previously recorded filtration capacity is close to or has been exhausted, and the washing program will not run.

A specific structure of the water level detection device 580 in this embodiment is shown in FIG. 3 , including a step structure 582 and multiple sets of water level probes 581 arranged on the step structure 582 . According to the on-off status of each set of water level probes 581, the current water level in the recovery device 500 can be determined. For example, the overflow water level is set to the height of the step surface corresponding to the highest set of water level probes 581. When the highest set of water level probes 581 are turned on, it is judged that the filtration capacity of the filter module is close to or has been exhausted. .

Using the water level detection device 580 with the above structure, the water level in the recovery device 500 can also continue to rise, so that each group of water level detection devices can When the needles 581 are turned on one by one, the time when each water level probe 581 is turned on is obtained, and then the water level change rate is calculated based on the time difference between the different water level probes 581 being turned on.

Or, after any group of water level probes 581 is turned on, and after a set time has passed, its adjacent higher water level probe 581 has not been turned on, then it is judged that the current water level change rate is too low, and the filter The module's filtering capacity is close to or has been exhausted. For example, when a group of water level probes 581 is turned on and after a set time has elapsed, a group of water level probes 581 on the adjacent higher step surface are still disconnected, then it is judged that the filtration capacity of the filter module is close to or Already exhausted.

Using the water level detection device 580 with the above structure, the specific water level in the recovery device 500 can be obtained in real time, and it can be determined whether the current water level reaches the overflow level. The water level change rate can also be calculated based on the detected real-time changes in water level height, and whether the filtration capacity of the filtration module is close to or exhausted is judged based on whether the water level change rate is close to zero. In this way, the water level detection in the recovery device 500 is more accurate.

Specifically, the water level detection device 580 can detect the water level in the space outside the wire scrap collection assembly 570 in the recovery device 500, determine the remaining capacity in the recovery device 500 based on the detected water level, and then determine whether the filtration capacity of the filter module is lower than a preset value. value.

The water level detection device 580 can also detect the water level change rate in the recovery device 500. When the detected water level change rate drops to close to zero, it means that the lint collection assembly 570 is blocked, causing the received sewage to be unable to be filtered and flow to the lint. The outside of the collection assembly 570 or the filtering device 600 is clogged, causing the sewage to be unable to be smoothly discharged into the recovery device 500 . Both of the above situations reflect the decline in the filtering capacity of the filter module.

In this embodiment, the washing equipment can retrieve the previously recorded filtration capacity of the filter module before starting the washing program. When the filtration capacity is insufficient, especially when the filtration capacity is close to or has been exhausted, the washing program is controlled not to run, and the washing program is controlled accordingly. Remind users. This avoids the problem of forcibly running the washing program when the filtration capacity of the filtration module is insufficient, resulting in the failure to realize the filtration function and affecting the cleaning effect of the clothes. It also prevents the water overflowing phenomenon of the recovery device 500.

Embodiment 19

As shown in Figures 1 and 7, the difference between this embodiment and the above-mentioned Embodiment 18 is that the washing equipment obtains the flow information of the sewage discharged by the filtering device 600 before the washing program ends, and determines the current filtration rate of the filter module based on the flow information. ability.

Specifically, the flow information is the flow rate of sewage discharged from the filtering device 600 . Before the washing process of the washing equipment ends, the filtering device 600 detects the sewage flow rate during the last process of discharging sewage into the recovery device 500. When the detected sewage flow rate is lower than the preset flow rate, it is determined that the filtering capacity is lower than the preset value.

Further, in this embodiment, when the sewage flow rate is detected to be close to zero, it is determined that the filtering capacity is close to or has been exhausted.

When the washing equipment detects that the sewage flow rate drops to close to zero, it means that the filtering device 600 is seriously blocked and cannot discharge sewage. At this time, it is recorded that the filtration capacity of the filtration module is close to or has been exhausted. When the washing equipment receives the instruction to start the washing program again, the filtering capacity recorded last time is close to or exhausted, and the washing program will not be started.

When the washing equipment detects that the sewage flow rate drops to close to zero, it means that the sewage currently discharged by the filtering device 600 is difficult to re-enter the recovery device 500. At this time, it is recorded that the filtering capacity of the filtering module is close to or has been exhausted. When the washing equipment receives the instruction to start the washing program again, The filtration capacity recorded last time is close to or exhausted, and the washing program will not start.

In this embodiment, the washing equipment determines the filtration capacity of the filter module by detecting the sewage discharge flow rate, mainly to determine whether the sewage discharge of the filter device 600 itself is smooth and whether the lint collection assembly 570 in the recovery device 500 is clogged. When the filtering device 600 itself is clogged, and the lint collection assembly 570 in the recycling device 500 is clogged, the filtering device 600 cannot discharge sewage into the recycling device 500 , which is equivalent to exhausting the filtering capacity of the filtering module. Under the above circumstances, the washing equipment will not start the washing program, thereby avoiding the problem of being unable to realize the filtering function during the laundry cleaning process.

Embodiment 20

The difference between this embodiment and the above-mentioned Embodiment 18 or 19 is that the preset value is equal to the minimum filtration capacity required to complete this washing process, that is, when the filtration capacity is lower than the minimum filtration capacity required to complete this washing process, At the lowest filtration capacity, it prompts that the washing program cannot be run.

Further, before the washing equipment receives the instruction to start the washing program, it also includes:

Receive the setting instructions of the washing program and determine the washing program to be run;

According to the washing program to be run, determine the corresponding minimum filtration capacity.

Specifically, after the user turns on the washing equipment, he sets the washing program he wants to run. The washing equipment can determine the washing program to be run according to the user's instructions for setting the washing program. The washing equipment pre-stores the corresponding relationship between different washing programs and the minimum filtration capacity required to complete the washing program. According to the determined washing program to be run, the corresponding minimum filtration capacity is retrieved from the corresponding relationship.

When the user triggers the program start button and the control system of the washing equipment receives the instruction to start the washing program, it can compare the previously recorded filtration capacity with the minimum filtration capacity. If it is lower than the minimum filtration capacity, it means that the current filtration capacity is not enough to complete this washing program, and it will prompt that the washing program cannot be run. If it is greater than or equal to the minimum filtration capacity, it means that the filtration module can complete this washing process, and then the washing program starts.

For different washing programs, the clothes being washed may be different, and the values of the washing parameters may be different. For example, clothes made of cotton and linen are more likely to shed lint during the washing process, and the washing intensity is relatively high, so the minimum filtration capacity required is relatively high. For clothes made of chemical fiber, less lint is shed during the washing process, or for clothes made of wool, the washing intensity is relatively weak due to poor wear resistance, and the corresponding minimum required filtration capacity may be relatively low. .

In this embodiment, the washing equipment determines the corresponding minimum filtration capacity according to the washing program to be run, and compares it with the previously recorded filtration capacity of the filter module to determine whether the washing program can be run. When the filtration capacity of the filtration module is low, if the washing program to be run does not require excessive filtration capacity, it may be able to complete the operation. At this time, the washing program can be started directly instead of requiring the user to clean the filter module. Operation is more intelligent.

Embodiment 21

Specifically, the washing equipment performs the filtration working condition of conducting water to the filter module during the running of the washing program. The washing equipment performs the filtration working condition including: the circulation pump 400 works to guide water to the filtering device 600 for filtering, and performs the process according to the set program. The filtering device 600 discharges sewage into the recovery device 500 in a sewage discharge operation.

The control method of the washing equipment described in this embodiment includes:

The washing equipment determines the minimum filtration capacity required for the washing process to complete the filtration conditions;

Obtain the filtration capacity of the filtration module and compare it with the minimum required filtration capacity to determine whether the washing program can be run.

Specifically, during the setup phase of the washing program, the washing equipment compares the filtration capacity of the filtration module with the minimum filtration capacity required by the washing program. If the minimum filtration capacity is less than or equal to the filtration capacity of the filter module, it is judged that the washing program can be run, otherwise it is judged that the washing program cannot be run.

Further, depending on whether the washing program can be run, whether the washing program can be selected is further controlled. That is to say, for the washing program that can be run, it can be selected in the setting stage of the washing program, otherwise it cannot be selected.

In this embodiment, when the user operates the washing equipment to set the washing program, the washing equipment can compare the filtration capacity of the filter module and the minimum filtration capacity required by the washing program to determine whether the washing program can be run, and then control whether the washing program can be operated by the user. selected. In this way, it can be avoided that the minimum filtration capacity required by the user's selected washing program exceeds the filtration capacity of the filter module, and prevents the user from The filtering module's filtering capacity is exhausted.

Specifically, the filtration capacity of the filtration module described in this embodiment includes: the smoothness of the water outlet of the filtration device 600, and/or the remaining capacity of the recovery device 500. The smoothness of the water outlet may be the smoothness of the filtering device 600 filtering water and outputting the filtered water, or the smoothness of the filtering device 600 discharging sewage to the outside. The filter device 600 needs to reach a certain degree of smooth water outlet before the washing program is started, so as to ensure that it will not be blocked during the entire operation of the washing program.

When the washing equipment performs filtration conditions during the washing process, it will perform sewage discharge operations multiple times according to the set program, causing the filtration device 600 to discharge sewage to the recovery device 500, so that the amount of sewage received in the recovery device 500 will increase during the washing process. gradually increases, and then the remaining capacity gradually decreases. If the recovery device 500 is filled with sewage, continuing to discharge sewage into it will cause the recovery device 500 to overflow, causing users to complain. Therefore, only when the remaining capacity of the recovery device 500 is no less than the total discharge volume of sewage during the entire washing process, it is possible to ensure that the washing process is successfully completed without the recovery device 500 overflowing.

In a further solution of this embodiment, the washing equipment has multiple washing programs, and the minimum filtration capacity required for each washing program to complete the filtration condition is pre-stored.

Different washing programs generally require different minimum filtration capacities. For example, washing programs suitable for cotton and linen materials are generally more intensive, and cotton and linen clothes are more likely to shed lint, resulting in a larger amount of lint produced during the washing process, which is relatively more likely to cause damage to the filter device. The clogging of 600 may also require the filtering device 600 to perform self-cleaning and sewage discharge more frequently, and thus the total amount of sewage discharged into the recovery device 500 during the washing process will be larger. Therefore, its required minimum filtration capacity is relatively high.

The washing program is suitable for chemical fiber materials, because clothes made of chemical fiber materials are relatively less likely to shed lint, or the washing program is suitable for wool materials, because wool clothing has poor abrasion resistance and relatively weak washing intensity. In turn, the above two The amount of lint generated during this washing process is relatively small, which causes the filtering device 600 to take longer to clog, and the total amount of sewage discharged into the recovery device 500 is relatively small. Therefore, the minimum filtration capacity required for the above washing procedures is relatively low.

By comparing the minimum filtration capacity required by the washing program with the filtration capacity of the filter module during the setting stage of the washing program, it is judged whether the washing program can be run, and then controls whether the washing program can be selected, ensuring that the final running washing program meets the requirements. The minimum filtration capacity does not exceed the filtration capacity of the filtration module, and the filter device 600 will not be blocked in the middle of the washing program, or the recovery device 500 will overflow during the washing program.

Further, the washing equipment compares the filtration capacity of the filtration module with the minimum filtration capacity required by each of the multiple washing programs to control whether the washing program can be selected. If the minimum filtration capacity is greater than the filtration capacity of the filter module, it is determined that the corresponding washing program cannot be run, and then the washing program is controlled not to be selected. And if the minimum filtration capacity is less than or equal to the filtration capacity of the filter module, it is determined that the corresponding washing program can be run, and the washing program is controlled to be selected.

Specifically, controlling whether the washing program can be selected includes: the washing equipment does not respond to the selection instruction of the unoperable washing program; and the washing equipment receives the selection instruction of one of the executable washing programs and determines the selected washing program as Wash program to be run.

In detail, the washing equipment will not be locked by the selected washing program, so that the user cannot select this part of the washing program. For example, when the washing equipment includes multiple program selection keys corresponding to different washing programs, if the user triggers the program selection key corresponding to the inoperable washing program, the washing equipment will not respond. Or, when the washing equipment sets the program selection knob for the user to select a program, if the program selection knob currently points to an inoperable washing program, the washing equipment does not respond when the user triggers the start command of the washing program.

In a preferred solution of this embodiment, when the user triggers a selection instruction for a washing program that is not operable, the washing equipment also sends a prompt message to remind the user that the selected washing program is not operable. The prompt information may be similar to "The washing program requires a large filtration capacity, and the current filtration capacity of the filter module cannot satisfy it. Please select another washing program."

In another preferred solution of this embodiment, the washing equipment locks inoperable washing programs and does not display them, and only displays executable washing programs for the user to choose from. For example, the washing equipment is equipped with multiple program display signs that correspond to different washing programs. For washing programs that can be run, the corresponding program display signs are in a fully illuminated state, while for washing programs that cannot be run, the corresponding program display signs are in a fully illuminated state. The display mark is half-lit or off. The user can know which washing programs can be run according to the display status of each program display mark, and then select from them.

In the above solution, the washing equipment directly compares the minimum filtration capacity required for each washing program with the filtration capacity of the filtration module, and controls the inoperable washing program not to be selected by the user, making it convenient for the user to directly select from the executable washing programs. Make your selection.

In a further solution of this embodiment, obtaining the filtration capability of the filter module by the washing equipment includes: obtaining the previous washing process run by the washing equipment. The current filtering capability of the filtering module recorded before the end of the sequence.

Specifically, the current filtering capacity of the filter module recorded before the end of the previous washing program of the washing equipment includes: the smoothness of the water outlet of the filter device 600 before the end of the previous washing program, and/or the recovery device 500 before the end of the previous washing program. remaining capacity.

In detail, during the process of running the washing program, the washing equipment conducts water to the filtration module for filtration. Before the end of the washing program, the current filtration capacity of the filter module is obtained and recorded for use in the setting phase of the next washing program. Based on the recorded filtration capacity, it is judged whether each washing program can be run.

In this embodiment, the filtration capacity of the filtration module includes the smoothness of the water outlet of the filtration device 600 and/or the remaining capacity of the recovery device 500 . In particular, the smoothness of the water outlet of the filtering device 600 can only be detected when the filter module is in working condition.

The washing equipment obtains the current filtration capacity of the filtration module before the end of each washing program and records it. After the washing program is completed, the next time the washing program is set, the filtering capacity recorded last time is directly retrieved to judge whether each washing program can be run. That is to say, during the setting stage of the washing program, the filter module does not need to enter the working state, and the washing equipment can judge whether its filtration capacity meets the operating requirements of each washing program.

Through the above method, the filtration capacity of the filtration module can be obtained before the washing equipment starts the washing program. There is no need to control the filtration module to continue working for a period of time. It is more in line with the operation logic to judge the filtration capacity during the setting stage of the washing program. .

As shown in Figure 19, the control method of the washing equipment in this embodiment specifically includes the following steps:

S101. The washing equipment is turned on and enters the setting stage of the washing program;

S102. Obtain the current filtration capacity of the filtration module recorded before the end of the previous washing program;

S103. Compare with the minimum filtration capacity required by each washing program;

S104. If the minimum filtration capacity is greater than the filtration capacity of the filter module, the corresponding washing program is locked; if the minimum filtration capacity is less than or equal to the filtration capacity of the filter module, the corresponding washing program can be selected.

In this embodiment, the washing equipment pre-stores the minimum filtration capacity required for each washing program to complete the filtration conditions. During the setting stage of the washing program, the minimum filtration capacity required for each washing program is compared with the filtration capacity of the filtration module. , determine whether each washing program can be run under the current status of the filtration module. At the same time, the washing program is screened so that only the washing program with the lowest filtration capacity not higher than the filtration capacity of the filtration module can be selected by the user, which avoids the user selecting a washing program that requires a higher filtration capacity, resulting in the inability to complete filtration when the washing program is running. working conditions.

Embodiment 22

The difference between this embodiment and the above-mentioned Embodiment 21 is that: in the setting stage of the washing program, the washing equipment first receives the user's selection instruction for the washing program, and then determines whether it can operate based on the minimum filtration capacity required for the selected washing program. .

Specifically, the control method of the washing equipment in this embodiment includes: the washing equipment receives a selection instruction for one of the washing procedures, compares the minimum filtration capacity required by the selected washing procedure with the filtration capacity of the filtration module, and determines the Whether the washing program can be run.

Further, when the minimum filtration capacity required by the selected washing program is less than or equal to the filtration capacity of the filter module, the selected washing program is determined as the washing program to be run. After receiving the instruction to start the washing program, the washing equipment runs the selected washing program.

In the above solution, the washing equipment does not need to compare the minimum filtration capacity required for each washing program with the filtration capacity of the filtration module one by one, and judge whether it can be run respectively. Instead, it directly judges the washing program selected by the user. If the filtration capacity of the filtration module can just meet the washing program selected by the user, the washing equipment can apply the washing program in subsequent runs. Compared with the above-mentioned Embodiment 1, the step of comparison one by one is omitted, thereby reducing the amount of calculations required by the washing equipment for comparison and judgment.

In a further solution of this embodiment, if the minimum filtration capacity required for the washing program selected by the user is greater than the filtration capacity of the filter module, it is judged that the currently selected washing program is not operable and the user needs to make a new selection.

Specifically, the washing equipment compares the minimum filtration capacity required by other washing procedures with the filtration capacity of the filtration module, and selects the washing procedures whose minimum filtration capacity is less than or equal to the filtration capacity of the filtration module from other washing procedures, and performs recommend. The user reselects from the recommended washing programs, and the washing equipment receives the user's selection instruction for one of the recommended washing programs and determines the corresponding washing program as the washing program to be run.

In the above solution, when it is judged that the washing program selected by the user cannot be run, the washing equipment will also recommend wash programs that can be run to the user for the user to choose from, avoiding the trouble of the user making multiple selections but still not being able to select a washing program that can be run. .

As shown in Figure 20, the control method of the washing equipment in this embodiment specifically includes the following steps:

S111. The washing equipment is turned on and enters the setting stage of the washing program;

S112. Receive the selection instruction of the washing program;

S113. Obtain the current filtration capacity of the filtration module recorded before the end of the previous washing program;

S114. Determine whether the filtration capacity of the filtration module is less than the minimum filtration capacity required by the selected washing program;

S115. If yes, recommend a washing program whose minimum required filtration capacity is less than or equal to the filtration capacity of the filter module; if not, determine the selected washing program as the washing program to be run.

In this embodiment, the washing equipment waits for the user to select a washing program first, and then directly compares the filtration capacity of the filter module with the minimum filtration capacity required for the washing program selected by the user to determine whether the washing program can be run. Only when the user selects a washing program whose required minimum filtration capacity exceeds the filtration capacity of the filtration module, the washing equipment will compare the minimum filtration capacities required by other washing programs with the filtration capacity of the filtration module. This can reduce the amount of calculations required by the washing equipment for comparison and judgment to a certain extent, and improve the data processing efficiency of the washing equipment in the washing program setting stage.

Embodiment 23

As shown in Figures 1 and 2, this embodiment is a further limitation of the above-mentioned Embodiment 21 or 22. The washing equipment determines the filtration capacity of the filtration module by obtaining the water level information in the recovery device 500.

Specifically, before the previous washing program ends, the washing equipment obtains the water level information in the recovery device 500 and determines the current filtering capacity of the filter module based on the water level information. In the current washing program setting stage, the washing equipment retrieves the filtration capacity of the filter module recorded previously and compares it with the minimum filtration capacity required by the washing program.

As a specific solution of this embodiment, the washing equipment detects the water level in the recovery device 500 before the washing process ends, and determines the current filtration capacity of the filtration module based on the water level. Specifically, the higher the detected water level, the lower the corresponding filtering capacity.

In the above scheme, the minimum filtration capacity required by the washing program to complete the filtration condition refers to the total amount of sewage that needs to be discharged into the recovery device 500 during the operation of the washing program, and the filtration capacity of the filtration module refers to the remaining capacity in the recovery device 500 . The water level in the recovery device 500 directly reflects the amount of sewage received in the recovery device 500. By detecting the water level in the recovery device 500, the remaining capacity in the recovery device 500 can be determined.

In detail, the total amount of sewage that needs to be discharged into the recovery device 500 during different washing programs is different. If the total amount of sewage that needs to be discharged by the washing program is greater than the remaining capacity of the recovery device 500, it will cause the recovery device to fail during the operation of the washing program. 500 overflows, or sewage cannot enter the recovery device 500. In this case, the minimum filtration capacity required for the washing program is greater than the filtration capacity of the filtration module.

On the contrary, if the total amount of sewage discharged by the washing process is less than or equal to the remaining capacity of the recovery device 500, then all the sewage discharged by the filtering device 600 can be received by the recovery device 500 during the operation of the washing process.

The washing equipment compares the minimum filtration capacity required by the washing program and the filtration capacity of the filter module, that is, compares the total amount of sewage discharged by the washing program and the remaining capacity of the recovery device 500. If the remaining capacity of the recovery device 500 is greater, then judge The washing program can be run, otherwise it is judged that the washing program cannot be run and cannot be selected by the user.

As another specific solution of this embodiment, before the end of the washing process, the washing equipment detects the water level change rate in the recovery device 500 when the filter device 600 discharges sewage into the recovery device 500 for the last time. According to the water level change rate Determine the current filtering capabilities of the filter module. Specifically, the smaller the detected water level change rate is, the lower the corresponding filtering capacity is.

After the filter device 600 performs self-cleaning, the cleaned filter impurities are discharged from the sewage outlet 6103 and enter the recovery device 500 along the sewage pipeline 240 . The faster the flow rate of sewage discharge, the greater the sewage flow rate, which is reflected in the change in water level height of the recovery device 500, that is, the higher the water level change rate. If local blockage occurs in the filtering device 600 due to the accumulation of filtered impurities, the flow rate of sewage discharge will be reduced, and the water level change rate will be reduced.

The washing equipment calculates the filtration capacity of the filtration module based on the detected water level change rate in the recovery device 500 and records it. During the next wash program setting phase, the filtration capacity recorded during the previous run can be retrieved and compared with the minimum filtration capacity required for the wash program. If the recorded filtering capacity is greater, it is judged that the washing program can be run, otherwise it is judged that the washing program cannot be run and cannot be selected by the user.

In this embodiment, in order to detect the water level information in the recovery device 500, a water level detection device 580 is provided inside the recovery device 500. The specific structure of the water level detection device 580 can be shown in FIG. 3 , including a step structure 582 and multiple sets of water level probes 581 arranged on the step structure 582 . Alternatively, the specific structure of the water level detection device 580 may be an electrode type water level detection device 583 as shown in FIG. 4 .

The working modes of the specific structures of the above two water level detection devices 580 have been described in detail in the first embodiment, and will not be described again in this embodiment.

In this embodiment, the filter module may also have a specific structure as shown in FIG. 5 , which shows a top structural view of the recovery device 500 . The lint collection assembly 570 is a filter structure surrounding a collection cavity. The water level detection device 580 can detect the water level in the space outside the lint collection assembly 570 in the recovery device 500, and determine the remaining capacity in the recovery device 500 based on the detected water level. , and then judge the filtering capability of the filter module.

In this embodiment, the washing equipment estimates the filtration capacity of the filtration module based on the water level information in the recovery device 500, and compares it with the minimum filtration capacity required by different washing procedures to determine whether the washing procedure can be run, thereby realizing the control of the washing procedure. Whether it can be controlled by user selection avoids the situation where the filtration capacity of the filtration module cannot support the washing process to complete the filtration working conditions.

Embodiment 24

As shown in Figures 1 and 7, this embodiment is a further limitation of the above-mentioned Embodiment 21 or 22. The washing equipment determines the filtration capacity of the filtration module by obtaining flow information of sewage discharged from the filtration device 600.

Specifically, before the previous washing program ends, the washing equipment obtains the flow information of the sewage discharged by the filtering device 600, and determines the current filtering capacity of the filter module based on the flow information. In the current washing program setting stage, the washing equipment retrieves the filtration capacity of the filter module recorded previously and compares it with the minimum filtration capacity required by the washing program.

In this embodiment, the flow information is the flow rate of sewage discharged by the filtering device 600. Before the washing process of the washing equipment ends, the filtering device 600 detects the sewage flow during the last process of discharging sewage into the recovery device 500, and calculates the filtration capacity of the filtration module based on the sewage flow. The smaller the detected sewage flow is, the lower the corresponding filtration capacity is.

There are generally two factors that affect the sewage flow.

1. As the amount of accumulated filtered impurities gradually increases, local blockage occurs inside the filtering device 600, or when filtered impurities accumulate locally in the sewage pipeline 240 and a certain degree of blockage occurs, the sewage will be discharged from the filtering device 600 into the recovery device. 500 is blocked, which in turn leads to a decrease in sewage flow.

Second, as the recovery device 500 receives the sewage and filters the sewage through the lint collection assembly 570, the filtered impurities gradually cover the surface of the lint collection assembly 570. When the lint collection component 570 is clogged by filtering impurities and cannot filter the received sewage, the sewage will gradually fill the first chamber 531 because it cannot pass through the lint collection component 570 and enter the second chamber 532 . For the case where the recovery chamber inside the recovery device 500 has a relatively sealed structure, when the first chamber 531 is filled or nearly full with sewage, the resistance encountered by subsequent sewage when entering the recovery device 500 becomes greater. If the filtering device 600 does not use additional driving force in the process of discharging sewage to the recovery device 500, but only relies on the gravity of the sewage itself to complete the sewage discharging operation, it will be difficult for the sewage to enter the recovery device 500, resulting in a decrease in the sewage flow rate.

The washing equipment calculates the filtration capacity of the filtration module based on the detected sewage flow and records it. During the next wash program setting phase, the filtration capacity recorded during the previous run can be retrieved and compared with the minimum filtration capacity required for the wash program. If the recorded filtering capacity is greater, it is judged that the washing program can be run, otherwise it is judged that the washing program cannot be run and cannot be selected by the user.

In order to detect the sewage flow, the washing equipment of this embodiment is provided with a flow meter 243 on the sewage pipeline 240. The flow meter 243 is specifically arranged upstream of the sewage control valve 241 and can detect the sewage flow in the sewage pipeline 240. , and then determine the current filtering capability of the filter module.

In this embodiment, the washing equipment estimates the filtration capacity of the filter module by detecting the sewage discharge flow rate, mainly to determine whether the sewage discharge of the filter device 600 itself is smooth and the degree of blockage of the lint collection assembly 570 in the recovery device 500, and convert it into An indicator that can be directly compared to the minimum filtration capacity required for a washing program. The washing equipment determines whether the washing program can be run based on the comparison results, and then controls whether each washing program can be selected by the user to ensure that the final running washing program meets the filtration capacity of the filtration module.

Embodiment 25

The difference between this embodiment and the above embodiment is that the washing equipment estimates the minimum filtration capacity required for the washing program during the setting stage of the washing program.

Specifically, the washing equipment determines the minimum filtration capacity required for the washing program based on the clothing material to which the washing program is applicable and/or the washing parameter values of the washing program.

Since the minimum filtration capacity required by a washing program is related to the total amount of lint shed on the clothes during the washing process, the washing equipment can determine the minimum filtration capacity required based on the material of the clothes that the washing program is applicable to, such as the minimum required by the cotton and linen washing program. The filtration capacity is relatively high, and the minimum filtration capacity required for wool washing procedures or chemical fiber washing procedures is relatively low.

Different washing programs also have different washing parameters, such as washing speed, washing time, rinse times, etc. The higher the washing speed and the stronger the washing force, the easier it is to cause lint to fall off the clothes. The longer the washing time and the more times of rinsing, the longer the total execution time of the filtration operation will be, and the greater the required minimum filtration capacity will be.

Compared with the previous embodiment, this embodiment no longer pre-stores the minimum filtration capacity required for each washing program, but can independently determine the level of the minimum filtration capacity based on the clothing material and washing parameter values applicable to each washing program. Washing equipment with a large number of washing programs avoids the trouble of pre-stored large amounts of data.

On the other hand, for programs that pre-store the minimum filtration capacity required for each washing program, generally different minimum filtration capacities can only be pre-stored according to the type of washing program, such as cotton and linen washing programs, wool washing programs, chemical fiber washing programs, etc. Different minimum filtration capacities. However, when setting the washing program, the user may also set different washing parameter values. The washing equipment cannot preset the changes in the values of various washing parameters, which results in the pre-stored minimum filtration capacity being different from the actual requirements of the washing program set by the user. The minimum filtration capabilities are not exactly the same. In this embodiment, the washing equipment can determine the minimum filtration capacity required for the washing program based on the clothing material applicable to the washing program and the values of the washing parameters of the washing program, which is more accurate.

Embodiment 26

As shown in Figures 1 and 11, this embodiment is a further limitation of any one of the above embodiments. The washing equipment performs an additional procedure of conducting water filtration to the filtration module during the washing procedure, wherein each time a washing is completed When the program is run, the additional program is executed once.

In this embodiment, the filtering capacity of the filter module is defined as: the number of times the filter module can continue to execute additional programs in the current state until the filter device 600 and/or the recovery device 500 is clogged.

The initial filtration capacity of the filtration module is at least 10 to 30 times, preferably 15 to 25 times. For example, the initial filtration capacity of the filtration module is at least 20 times. That is to say, when no filter impurities are attached in the filter device 600 and no filter impurities and sewage are collected in the recovery device 500, the filter module can at least continuously operate. The additional program can be fully executed in the 20 wash programs without clogging failure.

In the above description of this embodiment, the "completely executing the additional program" refers to performing cycle filtration according to the set time in the washing stage and rinsing stage respectively, and performing drainage filtration in the drainage stage.

Each time the filtration module completes an additional program in the washing program, the washing equipment records the current filtration capacity of the filtration module and subtracts one time from the original filtration capacity. If in this washing program, the filtration module performs cyclic filtration for less than the set time, the loss of filtration capacity in this washing program can be determined based on the ratio of the actual filtration time to the set time, and then the filtration capacity can be calculated. The current filtering capabilities of the module.

In a preferred solution of this embodiment, the value of the filtering threshold is set to 1 or 2. When the current filtration capacity of the filtration module is lower than the filtration threshold, the control stops transferring water to the filtration module, and cyclic filtration will no longer be performed in the follow-up process of this washing program.

In the above scheme, when the washing equipment calculates that the filtration capacity of the filtration module is close to 0 but has not yet reached 0, it controls to stop transferring water to the filtration module to avoid deviations between the calculation of the filtration capacity and the current actual status of the filtration module, resulting in future It can promptly control the problem of stopping water transfer to the filter module before the filter module becomes clogged or otherwise malfunctions.

In another preferred solution of this embodiment, the initial filtering capability of the filtering module is recorded as X, and the value of the filtering threshold is set to X/5 to X/3. For example, if the initial filtering capability of the filtering module is 20 times, the value of the filtering threshold can be set to 4 to 6 times. When the current filtration capacity of the filtration module is lower than the filtration threshold, the frequency and/or duration of water transfer to the filtration module is controlled to be reduced.

In the above scheme, the value of the filtering threshold is relatively high. Even if there is a deviation between the calculation of the filtering capacity by the washing equipment and the current actual status of the filtering module, it will basically not happen that the filtering module has failed when the calculated filtering capacity is lower than the filtering threshold. There is a blockage or other failure that affects the filtration effect. At this time, by reducing the frequency and/or duration of water transfer to the filter module and continuing to run the washing program, part of the filtering effect can be retained and the clothes cleaning effect can be improved.

The specific manner of reducing the frequency and/or duration of water delivery to the filter module has been described in detail in the above embodiments, and will not be described again in this embodiment.

In a further solution of this embodiment, the washing water and washing equipment drainage are filtered through the filtering device 600 to filter out impurities with a size greater than 50 μm, and the filtered impurities may include microplastics. In particular, the filtered impurities may include plastic fibers with a length greater than 50 μm and a diameter of 10 to 1000 μm. Preferably, the plastic fiber has a length of 400 to 600 μm, with the most common length in the distribution being The degree is 500μm±50μm. The diameter of these plastic fibers is preferably 10 to 50 μm, most commonly having a diameter of 17 μm ± 2 μm.

In order to filter and remove microplastics of the above-mentioned sizes, the filter screen in the filtering device 600 is selected from 20 mesh to 500 mesh. In order to ensure that the recycling device 500 can collect the microplastics carried in the sewage as fully as possible, there will be no problem that the microplastics filtered out by the filtering device 600 can pass through the lint collection assembly 570 in the recycling device 500. The size of the pores on the filter in the collection assembly 570 is at least not larger than the pore size of the filter in the filter device 600, that is, the mesh number of the filter in the lint collection assembly 570 is not less than the mesh number of the filter in the filter device 600, from 20 mesh to 500 mesh.

In this embodiment, by conducting a large number of tests on different types of clothes and different washing procedures in advance, it is found that the mesh number of the filter screen in the lint collection assembly 570 and the mesh number of the filter screen in the filter device 600 are set within the above range. , the plastic fibers of the above sizes can be filtered out from the washing water and the drainage of the washing equipment, and finally the microplastic particles accounting for more than 80% of the total content in the water can be collected in the recycling device 500, so that the final drainage water of the washing equipment contains microplastics. The content has dropped significantly and can meet the direct emission standards.

In this embodiment, since the filtering device 600 has a self-cleaning function, the filtering capacity loss of the filtering module is mainly reflected in the recovery device 500 . For example, as the total amount of filtered impurities collected in the recovery device 500 increases, the lint collection component 570 is gradually covered by the filtered impurities. The filtered impurities block the mesh on the filter, causing the lint collection component 570 to be unable to filter sewage.

In this embodiment, by conducting a large number of tests on different types of clothes and different washing procedures in advance, the structure of the lint collection component 570 is adjusted to change the maximum amount of filtered impurities it can collect, so that the filter module can be used when the user does not use the recovery device 500 On the premise of cleaning, the additional program can be completely executed in at least 10 to 30 consecutive washing programs, ensuring the user's user experience.

Embodiment 27

As shown in FIGS. 21 to 26 , the washing equipment in this embodiment includes a water tank 100 and a filtering device 600 for filtering water in the water tank 100 . The washing equipment may be a washing machine, a washer-dryer, a care machine and other washing equipment with a clothes cleaning function.

When the washing equipment is washing clothes, the water in the water tank 100 is introduced into the filtering device 600 for circulation filtration, which can filter out impurities such as lint in the water and improve the cleaning effect of the clothes. When the washing equipment is drained, the water in the water tank 100 is introduced into the filtering device 600, and is filtered by the filtering device 600 before being discharged outward. This can avoid filtered impurities carrying microplastics being discharged directly.

In detail, the filtering device 600 is provided with a water inlet 6101 for water inlet and a filtered water outlet 6102 for filtered water. The bottom of the water container 100 is connected to the water container drain pipe 260. The water container drain pipe 260 is connected to the inlet end of the circulation pump 400. The outlet end of the circulation pump 400 is connected to the circulation pipeline 220. The circulation pipeline 220 is in turn connected to the water inlet 6101 of the filtering device 600. connect. The filtered water outlet 6102 of the filtering device 600 is connected to the water tank 100 through the return pipe 230 . The water outlet end of the return pipe 230 is specifically connected to the window gasket 110 at the mouth of the water tank 100, and water is returned to the water tank 100 through the window gasket 110.

In a further solution of this embodiment, a control valve assembly 700 having a first valve body is provided between the filtered water outlet 6102 of the filtering device 600 and the return water pipeline 230, and the filtered water outlet 6102 is connected to the first valve body. The first valve body is respectively connected to the return water pipeline 230 and the external discharge pipeline 250 for draining water to the outside of the washing equipment. A switching mechanism 712 is provided inside the first valve body, which can control the return water pipeline 230 and the external discharge pipeline 250 to selectively connect to the filtered water. Exit 6102 is on.

Specifically, referring to FIG. 22 , when the washing equipment performs circulation filtration, the switching mechanism 712 blocks the opening on the upper part of the first valve body, so that the filtered water from the filter device 600 enters the return pipe 230 and returns to the water tank 100 . Referring to FIG. 6 , when the washing equipment drains water, the switching mechanism 712 blocks the opening on the side of the first valve body, so that the filtered water from the filter device 600 enters the external discharge pipe 250 and is discharged.

By setting the control valve assembly 700 and a filtering device 600 in the washing equipment, it is possible to realize two filtering functions: circulation filtration during the washing process and drainage filtration during the drainage process. At the same time, circulation filtration and drainage filtration share the circulation pump 400 and part of the pipeline structure, which simplifies the waterway control structure inside the washing equipment. By controlling the action of the switching mechanism 712, the function switching between circulation filtration and drainage filtration can be realized, and the control logic is simple.

In this embodiment, the filter device 600 can autonomously clean the filter impurities accumulated during the filtration process, and discharge the cleaned filter impurities outward through the drain outlet 6103 provided on the filter device 600 , thus avoiding the user's trouble of manually cleaning the filter device 600 . The washing equipment adopts the following control method to ensure that the filtering device 600 will not be blocked by filtered impurities during a complete washing program operation and cannot achieve the process. Filter function problem.

Specifically, the control method includes: during the operation of the washing program, controlling the filtering device 600 to perform a self-cleaning operation to clean filter impurities and/or a sewage discharge operation to discharge sewage carrying filtered impurities, so that the filtering capacity of the filtering device 600 Not less than the filtering threshold.

In this embodiment, the filtering capacity of the filtering device 600 specifically refers to the smoothness with which the filtering device 600 filters out water. When the current filtering capacity of the filtering module is lower than the filtering threshold, it means that it is difficult for the filtering device 600 to filter out water, that is, filtering The device 600 is clogged to a certain extent, which affects the filtration efficiency.

Alternatively, the filtering capacity of the filtering device 600 may also refer to the length of time that the filtering device 600 can continue filtering before being blocked by filtered impurities. When the filtration capacity of the filtration device 600 is lower than the filtration threshold, that is, if the filtration device 600 continues to perform filtration, it will soon become clogged, making it impossible to filter water.

In the above solution, the filter device 600 can clean the attached filter impurities through a self-cleaning operation during the washing process, and/or discharge the accumulated filter impurities with the water flow through a sewage discharge operation, thereby avoiding clogging of the filter impurities in the middle of the washing process. The filtering device 600 cannot continue to perform the filtering function. During the operation of the washing program, the washing equipment controls the filtering device 600 to perform a self-cleaning operation and/or a sewage discharge operation to ensure that the filtering device 600 always has sufficient filtering capacity to continue to implement the filtering function, so that this washing program can ensure the filtering effect. The operation was successfully completed.

In a further solution of this embodiment, the filtering device 600 includes:

The filtering mechanism 620 is rotatably arranged inside the filtering cavity 610 to filter the water entering the filtering cavity 610;

The filter mechanism 620 divides the interior of the filter cavity 610 into an outer cavity and an inner cavity, wherein the water inlet 6101 is connected to the outer cavity, and the filtered water outlet 6102 is connected to the inner cavity. The water in the water cylinder 100 enters the outer chamber through the water inlet 6101 under the action of the circulation pump 400, passes through the filter mechanism 620 and enters the inner chamber to achieve filtration. The filter impurities carried in the water are collected on the inner wall of the filter cavity 610 and the filter mechanism. 620, and most of them are attached to the outer wall of the filtering mechanism 620.

One end of the filtering mechanism 620 has a water outlet joint 621 that is rotatably and sealably connected to the filtered water outlet 6102. The filtered water can flow out from the filtered water outlet 6102 through the water outlet connector 621. In detail, the filtering mechanism 620 includes a filter bracket and a filter mesh covering the filter bracket. One end of the filter bracket extends into the filtered water outlet 6102 to form a water outlet joint 621.

Using the filter device 600 with the above structure, the self-cleaning operation includes: opening the driving mechanism 660 and driving the filter mechanism 620 to rotate and clean the attached filter impurities. The driving mechanism 660 may be a driving motor. When driving the filtering mechanism 620 to rotate, the driving motor rotates at the same speed as the filtering mechanism 620. The rotating speed is preferably 400 to 800 rpm.

In the above scheme, the filtering device 600 is controlled to perform a self-cleaning operation. The filtering mechanism 620 rotates at a high speed under the drive of the driving mechanism 660, which can stir the water flow in the filtering cavity 610, causing the filtered impurities attached to the outer wall of the filtering mechanism 620 to be removed by centrifugal force. It is peeled off under the dual action of water flow and agitation, and blended into the water in the filter cavity 610. In this way, the purpose of fully cleaning the attached filter impurities can be achieved, and the problem that some filter impurities are too firmly attached to the outer wall of the filter mechanism 620 and cannot be discharged can be avoided.

The sewage outlet 6103 of the filtering device 600 is connected to a sewage pipeline 240. The sewage operation includes: controlling the sewage outlet 6103 to communicate with the sewage pipeline 240, and discharging the sewage in the filter cavity 610 through the sewage outlet 6103. By performing a self-cleaning operation, the filter device 600 can avoid the problem of filter impurities adhering to the outer wall of the filter mechanism 620 and affecting the filtering efficiency. However, if there are too many filter impurities accumulated, even if the filter impurities are not attached to the outer wall of the filter mechanism 620, they will occupy most of the space in the filter cavity 610 and affect the filtration efficiency. By performing the sewage discharge operation to discharge filter impurities, the accumulation of filter impurities can be prevented and the filtration effect can be further ensured.

In the preferred solution of this embodiment, the sewage discharge operation further includes: during the process of discharging sewage, turning on the driving mechanism 660 to drive the filtering mechanism 620 to rotate. During the sewage discharge process, controlling the rotation of the filter mechanism 620 can fully stir the sewage in the filter cavity 610, preventing filter impurities such as lint in the sewage from depositing at the bottom of the filter cavity 610 and being unable to be driven out by the water flow, thereby effectively improving the efficiency of the sewage. The efficiency of filtering impurities.

More preferably, during the sewage discharge operation, the circulation pump 400 is controlled to be in a running state, and the water in the water tank 100 is pressed into the filter device 600 to drive the sewage in the filter device 600 to be discharged more fully.

Furthermore, cleaning particles 680 are provided between the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620 of the filter device 600 in this embodiment, for cleaning the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620 by friction and collision with the water flow. During the filtration process, the cleaning particles 680 continuously rub against the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620 with the flowing water, causing the attached filter impurities to fall off, thereby preventing the deposition of filter impurities. On the one hand, it prevents the filtering mechanism 620 from being covered by filtered impurities too quickly and affecting the filtering efficiency. On the other hand, it also avoids the problem that the filter impurities attached after the filtration are too thick and adhere too firmly to the inner wall of the filter cavity 610 or the outer wall of the filter mechanism 620, making it difficult to remove the filter impurities when cleaning the filter device 600 later.

When the driving mechanism 660 drives the filter mechanism 620 to rotate in the filter cavity 610 to clean the filtered impurities, the cleaning particles 680 move in the filter cavity 610 with the action of the turbulent water flow, and interact with the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620 Friction occurs, thereby improving the peeling efficiency of filtered impurities, and the self-cleaning effect of the filter device 600 is better.

In a further solution of this embodiment, in order to control the connection between the sewage outlet 6103 and the sewage pipeline 240, the control valve assembly 700 also includes a second valve body, and the second valve body is connected to the first valve body. Forming an overall structure, but not interconnected internally. The sewage outlet 6103 of the filtering device 600 and the sewage pipeline 240 are respectively connected with the second valve body. A blocking mechanism 722 is provided inside the second valve body for controlling the opening/closing of the second valve body and the sewage pipeline. 240 connected openings.

Referring to Figures 22 and 26, when the filtering device 600 performs filtration, the blocking mechanism 722 moves to the lower space of the second valve body to prevent communication between the sewage outlet 6103 and the sewage pipeline 240. When the filter device 600 performs a sewage discharge operation, referring to Figure 24, the blocking mechanism 722 moves upward to connect the sewage outlet 6103 and the sewage pipeline 240. The sewage in the filter cavity 610 can enter the sewage pipeline 240 through the sewage outlet 6103 to achieve filtration. Discharge of impurities.

In a further solution of this embodiment, during the filtering process of the filtering device 600, the washing equipment detects the filtered water flow rate of the filtering device 600, and controls whether the filtering device 600 performs a self-cleaning operation and/or a sewage discharge operation based on the detected filtered water flow rate.

Specifically, as shown in Figures 21 and 27, if the detected filtered water flow rate is less than a preset value, the filtering device 600 is controlled to perform a self-cleaning operation and/or a sewage discharge operation.

In the above solution, when the driving force provided by the circulation pump 400 remains stable, the greater the flow rate of the filtered water, the smoother the filtering device 600 can filter the water. As the accumulated filter impurities inside the filter device 600 increase, the flow rate of the filtered water will decrease to a certain extent. When it is detected that the flow rate of the filtered water is lower than the preset value, it indicates that the current degree of clogging is serious and affects the filtration efficiency. At this time, the filtering device 600 needs to be controlled to clean and discharge the filtered impurities.

In a preferred solution of this embodiment, the preset value includes a first preset value and a second preset value, wherein the first preset value is greater than the second preset value. When the filtered water flow rate is less than the first preset value but greater than the second preset value, the filtering device 600 is controlled to perform a self-cleaning operation. When the filtered water flow rate is less than the second preset value, the filtering device 600 is controlled to perform a self-cleaning operation and a sewage discharge operation in sequence.

In this embodiment, in order to detect the flow rate of the filtered water, a flow rate detection device 232 is provided on the return water pipeline 230 . The flow rate detection device 232 detects the flow rate of water in the return pipe 230. When the flow rate of the water flow is lower than a preset value, the drive mechanism 660 is controlled to open, causing the filter mechanism 620 to rotate to peel off the attached filter impurities. At the same time that the driving mechanism 660 is turned on, or after a certain period of time after the driving mechanism 660 is turned on, the blocking mechanism 722 in the control valve assembly 700 operates to connect the sewage outlet 6103 with the sewage pipeline 240, allowing the filtered impurities to be discharged from the filter device 600 with the water flow. .

Specifically, when the washing equipment performs circulation filtration, that is, when the control valve assembly 700 guides the filtered water outlet 6102 and the return water pipeline 230 through filtered impurities 600, and the circulation pump 400 is in the on state, the washing equipment obtains the flow rate detected by the flow rate detection device 232. The filtered water flow rate is compared with the preset value. When the filtered water flow rate is lower than the preset value, the impurity filter 600 is controlled to perform a self-cleaning operation and/or a sewage discharge operation.

In another solution of this embodiment, the flow rate detection device can also be arranged on the outer discharge pipeline to detect the flow rate of the filtered water during the drainage filtration process, thereby controlling whether the filter device performs a self-cleaning operation and/or a sewage discharge operation. However, it is understandable that during the operation of a complete washing program, the total time for the washing equipment to perform circulation filtration is generally greater than the total time for drainage filtration. Therefore, it is easier to detect the clogging of the filter device in time by detecting the flow rate of the filtered water during the circulating filtration process, and then control the filter device to clean and discharge filter impurities in a more timely manner.

Alternatively, in this embodiment, the length of the pipeline between the filtered water outlet of the filter device and the control valve assembly can be appropriately extended, and a flow rate detection device can be provided on the pipeline to detect the flow rate of the filtered water. In this way, whether during the circulation filtration process or the drainage filtration process, the filtered water flow rate can be obtained, and the filter device can be controlled to clean and discharge filter impurities in a more timely manner.

In a further solution of this embodiment, when the filter device 600 performs a self-cleaning operation and/or a sewage discharge operation, the washing equipment obtains the filtered water flow rate detected before the self-cleaning operation and/or the sewage discharge operation, and controls the drive according to the filtered water flow rate. The mechanism 660 drives the filter mechanism 620 to rotate at a rotating speed.

Specifically, the rotation speed of the driving mechanism 660 has a similar inverse relationship with the flow rate of the filtered water. That is, the slower the flow rate of the filtered water is, the greater the rotation speed of the driving mechanism 660 is. Generally speaking, the slower the filtered water flow rate is, the greater the degree of blockage of the filtering device 600 by filtered impurities is. Seriously, for example, the accumulation of filter impurities is greater, or the thickness attached to the outer wall of the filter mechanism 620 is greater. In order to fully clean and discharge the filtered impurities, the driving mechanism 660 is required to drive the filtering mechanism 620 to rotate at a higher speed, thereby providing greater centrifugal force to peel off the filtered impurities.

In detail, in this embodiment, the washing equipment obtains the current water flow rate in the return water pipeline 230 every certain time interval during the cycle filtration process, and compares it with the preset value. If the flow rate is less than the preset value, the cyclic filtration process is suspended, and the filtration device 600 is controlled to perform a self-cleaning operation and/or a sewage discharge operation. At the same time, the washing equipment determines the required rotation speed of the filter mechanism 620 based on the water flow rate obtained this time, and controls the driving mechanism 660 to drive the filter mechanism 620 to rotate at the rotation speed.

In this embodiment, the washing equipment can control the rotation of the filter mechanism 620 of the filter device 600 during the operation of the washing program to clean the attached filter impurities. It can also control the connection between the sewage outlet 6103 and the sewage pipeline 240 to allow the filtered impurities to flow with the water flow. discharge. The washing equipment controls when the filter device 600 performs a self-cleaning operation and/or a sewage discharge operation by detecting the flow rate of the filtered water, so that the filter device 600 can clean out accumulated filter impurities in the middle of the washing program without affecting the operation of this washing program. filter effect.

Embodiment 28

As shown in Figures 21 to 26, the difference between this embodiment and the above-mentioned Embodiment 27 is that the driving mechanism 660 uses a fixed rotation speed to drive the filter mechanism 620 to rotate to clean the filtered impurities.

Specifically, each time the filter device 600 is controlled to perform a self-cleaning operation, the driving mechanism 660 rotates at the same rotation speed, and then drives the filter mechanism 620 to rotate at the same rotation speed, using centrifugal force to detach the attached filter impurities.

In this embodiment, the fixed rotation speed is preferably 400 to 800 rpm.

In a further solution of this embodiment, when the filtering device 600 is controlled to perform a sewage discharge operation, the driving mechanism 660 is also turned on to drive the filtering mechanism 620 to rotate. In each sewage discharge operation, the driving mechanism 660 drives the filter mechanism 620 to rotate at the same rotation speed.

Preferably, when the filter device 600 performs the self-cleaning operation and the sewage discharge operation, the driving mechanism 660 drives the filtering mechanism 620 to rotate at the same rotation speed.

In this embodiment, the output speed of the driving mechanism 660 is always the same, and a fixed-speed motor can be used as the driving mechanism 660, which is beneficial to reducing production costs. At the same time, since the driving mechanism 660 does not need to change the rotation speed, the control step of determining the rotation speed can be omitted, making the control logic of the washing equipment simpler. On the other hand, the driving mechanism 660 adopts a fixed rotation speed, and the washing equipment only needs to issue start/stop control instructions to it, without controlling its rotation speed, and the control is easier to achieve.

Embodiment 29

As shown in Figures 21 to 26, the difference between this embodiment and the twenty-seventh and twenty-eighth embodiments mentioned above is that the preset filter device 600 of the washing equipment starts to execute the program node of the self-cleaning operation and/or the sewage discharge operation. During program running, if the program node is reached, the filtering device 600 is controlled to perform a self-cleaning operation and/or a sewage discharge operation.

In this embodiment, the washing equipment no longer controls the execution of the self-cleaning operation and the sewage discharge operation according to the real-time working status of the filtering device 600, but presets a fixed program node. Each time the program node is reached, the filtering device is controlled accordingly. 600 performs self-cleaning operations and/or blowdown operations.

In a specific solution of this embodiment, the program node refers to a specific running process in the washing program. When the washing program reaches a specific operation process, the filtering device 600 is controlled to perform a self-cleaning operation and/or a sewage discharge operation. Alternatively, multiple different running processes in the washing program are all set as the program nodes. During the running of the washing program, each time one of the running processes set as the program node is reached, the filtering device 600 is controlled to perform a self-cleaning operation and /or blowdown operations.

For example, the program nodes include wash drainage and rinse drainage. Then during the running of the washing program, when the washing phase is completed and washing and drainage are about to be performed, the filtering device 600 is controlled to perform a self-cleaning operation and/or a sewage discharge operation, and then washing and drainage is performed. The washing program continues to run. When each rinsing stage is completed and rinsing and draining are about to begin, the filtering device 600 is controlled to perform a self-cleaning operation and/or a sewage draining operation.

Preferably, the program node includes a first program node for controlling the execution of the self-cleaning operation, and a second program node for controlling the execution of the sewage operation. Wherein, the first program node includes wash drainage and every rinse drain, and the second program node includes wash drain and the last rinse drain.

The washing equipment runs a washing program, and before starting washing and drainage, the filtering device 600 is controlled to perform a self-cleaning operation and a sewage discharge operation in sequence. Before each subsequent intermediate rinsing and drainage, the filtering device 600 is controlled to only perform a self-cleaning operation and not to perform a sewage discharge operation. Before the last rinse and drainage, the filtering device 600 is controlled to perform a self-cleaning operation and a sewage discharge operation in sequence.

In the above scheme, the washing equipment performs circulating filtration in both the washing stage and the rinsing stage. Due to the intensity of cleaning of clothes during the washing phase The larger the size, the more lint will fall off the clothes, and more filter impurities will accumulate in the filter device 600 . Therefore, perform a sewage discharge operation before washing and draining to avoid affecting the filtration effect during subsequent rinsing. When performing cyclic filtration during the rinsing stage, the filtered impurities accumulated in the filter device are relatively small, and only the sewage discharge operation needs to be performed before the last rinsing and drainage.

In another specific solution of this embodiment, the program node refers to the time during which the filtering device 600 continuously performs filtering, and the cumulative number of times the filtering device performs self-cleaning operations. During the operation of the washing program, when the filtering device 600 continuously performs filtration (which may be cycle filtration or drainage filtration) for a certain period of time, the filtering device 600 is controlled to perform a self-cleaning operation and/or a sewage discharge operation.

As a specific implementation manner, each time the filtering device 600 continuously performs filtering for a first preset time period, the filtering device 600 is controlled to perform a self-cleaning operation.

Preferably, the washing equipment controls the filtering device to perform the sewage discharge operation according to the number of times the filtering device performs the self-cleaning operation. That is, when the filtering device 600 performs the self-cleaning operation for N times, after the current self-cleaning operation ends, the filtering device 600 is controlled to perform a sewage discharge operation, and then the number of times the filtering device 600 performs the self-cleaning operation is counted again from zero. The number of times N is preferably set to 2 to 5 times.

As another specific implementation, after a sewage discharge operation is completed, when the filtering device 600 continues filtering for a second preset time period, the filtering device 600 is controlled to perform a self-cleaning operation. Then, each time the filtering device 600 continuously performs filtering for a third preset time period (less than the second preset time period), the filtering device 600 is controlled to perform a self-cleaning operation. After the current blowdown operation ends, when the cumulative number of times the filtering device 600 performs the self-cleaning operation reaches N times, the filtering device 600 is controlled to perform a blowdown operation after the current self-cleaning operation ends.

In the above solution, the time for the filtering device 600 to continuously perform filtering can be determined based on the conduction state of the control valve assembly 700 and the working state of the circulation pump 400 . Specifically, when the control valve assembly 700 cuts off the communication between the sewage outlet 6103 and the sewage pipeline 240, the duration that the circulation pump 400 is in the on state is the time during which the filter device 600 continues to filter.

In a further solution of this embodiment, when the filter device 600 performs a self-cleaning operation and/or a sewage discharge operation, the method of controlling the rotation speed of the driving mechanism 660 is the same as in the first embodiment. That is, the filtered water flow rate of the filtering device 600 detected by the flow rate detection device 232 before the self-cleaning operation and/or the sewage discharge operation is performed is obtained, and the rotational speed of the driving mechanism 660 driving the filtering mechanism 620 is controlled based on the filtered water flow rate.

In another further solution of this embodiment, the method of controlling the rotation speed of the driving mechanism 660 is the same as that in the second embodiment. That is, the driving mechanism 660 uses a fixed rotation speed to drive the filter mechanism 620 to rotate to clean the filtered impurities. It can be understood that since there is no need to obtain the filtered water flow rate of the filtering device 600 in the above solution, the specific structure of the washing equipment can be as shown in Figures 28 and 29, that is, the return water pipeline 230 is no longer provided for flow rate detection. detection device.

In this embodiment, the washing equipment controls the filter device 600 to perform the self-cleaning operation and/or the sewage discharge operation through preset program nodes. There is no need to obtain the actual working status of the filter device 600, eliminating the need to determine whether the self-cleaning operation and/or need to be performed. Or the judgment steps of sewage discharge operation, the control logic is simpler.

Embodiment 30

As shown in Figures 28 and 29, the difference between this embodiment and the above-mentioned Embodiment 29 is that the washing equipment is preset with at least two different rotation speeds for controlling the drive mechanism 660 to drive the filter mechanism 620, and according to the current The program node controls the rotation speed used by the driving mechanism 660 to drive the filtering mechanism 620.

In the specific solution of this embodiment, for the closest self-cleaning operation before the sewage discharge operation, the driving mechanism 660 is controlled to drive the filtering mechanism 620 to rotate at the first rotation speed. For the closest self-cleaning operation after the blowdown operation, the driving mechanism 660 is controlled to rotate at a second rotational speed, and the second rotational speed is lower than the first rotational speed.

As a specific implementation of this embodiment, the process of running the washing program of the washing equipment includes the following steps:

S121. The filtering device 600 performs filtering to reach the preset program node;

S122. Control the filtering device 600 to perform a self-cleaning operation;

S123. The self-cleaning operation ends, the filtering device 600 continues filtering and returns to step S121;

S124. The above steps S121 to S123 are repeated multiple times to reach the preset program node again;

S125. Control the filtering device 600 to perform a self-cleaning operation, in which the driving mechanism 660 drives the filtering mechanism 620 to rotate at the first rotation speed;

S126. Control the filtering device 600 to perform a sewage discharge operation and discharge sewage carrying filtered impurities;

S127. The filtering device continues to filter and reaches the preset program node;

S128. Control the filtering device 600 to perform a self-cleaning operation, in which the driving mechanism 660 drives the filtering mechanism 620 to rotate at the second rotation speed;

S129. The self-cleaning operation ends, the filtering device 600 continues filtering and returns to step S121;

S1210 and steps S121 to S129 are repeatedly executed until the washing program ends.

In the above scheme, for the control process of the filter device 600 that performs multiple self-cleaning operations and then performs a sewage discharge operation, in the self-cleaning operation performed before the sewage discharge operation, the filter mechanism 620 has a relatively larger force by controlling the driving mechanism 660. Rotating speed. In this way, a greater centrifugal force can be generated to peel off the filter impurities attached to the outer wall of the filter mechanism 620 as much as possible, and then in the subsequent sewage discharge operation, the accumulated filtration in the filter device 600 can be more fully discharged. Impurities. After the sewage discharge operation, when the self-cleaning operation is performed again, since the accumulation of filter impurities is relatively small, the driving mechanism 660 is controlled to drive the filter mechanism 620 to rotate at a relatively low speed, so that most of the filter impurities can be cleaned.

In this embodiment, by controlling the driving mechanism 660 to use different rotational speeds to drive the filtering mechanism 620 to rotate in the two self-cleaning operations before and after the sewage discharge operation, it can not only ensure the cleaning efficiency of filtered impurities, but also avoid the need for the driving mechanism 660 to operate every time. , both it and the filter mechanism 620 are in a high-speed rotating state, and may be easily damaged after long-term use.

Embodiment 31

As shown in Figures 21 to 29, this embodiment is a further limitation of any one of the twenty-seventh to thirtieth embodiments. The filtering device 600 filters the washing water and washing equipment drainage, and can filter out particles larger than 50 μm filter impurities, which may include microplastics.

Furthermore, the filtered impurities may include plastic fibers with a length greater than 50 μm and a diameter of 10-1000 μm. Preferably, the plastic fiber has a length of 400 to 600 μm, and the most common length in the distribution is 500 μm ± 50 μm. The diameter of these plastic fibers is preferably 10 to 50 μm, most commonly having a diameter of 17 μm ± 2 μm.

In order to filter and remove microplastics or plastic fibers of the above-mentioned sizes, the filter screen in the filtering device 600 is selected from 20 mesh to 500 mesh. Through a large number of tests on different types of clothes and different washing procedures, when the mesh number of the filter in the filter device 600 is set to the above range, more than 80% of the total content in the water can be filtered out from the washing water and washing equipment drainage. Microplastic particles can significantly reduce the content of microplastics in the drainage water of the final washing equipment and can meet the standards for direct discharge.

In a further solution of this embodiment, for the washing equipment equipped with the recovery device 500, in order to ensure that the recovery device 500 can collect the microplastics carried in the received sewage as fully as possible, there will be no microplastics filtered out by the filtering device 600. The problem that plastic can pass through the lint collection assembly 570 in the recycling device 500 is that the size of the pores on the filter in the lint collection assembly 570 is at least not larger than the pore size of the filter in the filtering device 600 . That is, the mesh number of the filter screen in the lint collection assembly 570 should be no less than 20 meshes to 500 meshes than the mesh number of the filter screen in the filtering device 600 .

Using the above solution, microplastic particles accounting for more than 80% of the total content in the water can finally be collected in the recovery device 500, ensuring that the content of microplastics in the drainage of the washing equipment is very low and can meet the emission standards so that it can be discharged directly.

Embodiment 32

This embodiment provides a method for controlling a washing equipment. The washing equipment may be a washing machine, an integrated washing and drying machine, a nursing machine, and other washing equipment with a clothes cleaning function.

The washing equipment is provided with a filter module, and the washing equipment has an additional program for conducting water filtration to the filter module during the washing program. By performing the additional program, the lint content in the water can be reduced and the cleaning effect of the clothes can be improved.

Furthermore, filter impurities such as lint that are filtered out during the execution of the additional procedure will be collected in the filter module. The filter module is removably installed on the washing equipment. Users can regularly take out the filter module for manual cleaning to remove filter impurities collected therein, thereby preventing the filter module from being blocked by filter impurities and ensuring the filtering effect of the filter module.

As shown in Figure 30, in this embodiment, the control method of the washing equipment specifically includes:

Get the number of times the filter module is used;

Detection filter module is taken out;

Control the number of uses of the filter module to be cleared.

Specifically, the filter module can be installed on the washing equipment in a push-pull manner. The user can pull out the filter module for cleaning. After the cleaning is completed, the filter module can be pushed back into the washing equipment. In the description of this embodiment, the "removal" mentioned in "the filter module is taken out" can either refer to the filter module being completely removed from the washing equipment, that is, the filter module is separated from the washing equipment, or it can also refer to the filter module being removed. Extracted but not separated from the washing equipment.

In this embodiment, the counting rule for the number of uses of the filter module is: the washing equipment completes a washing program. If it is determined that an additional program has been executed in the washing program, the number of uses of the filter module is increased by one. That is to say, every time the washing program completes a washing program operation that performs an additional program, it is recorded as a use of the filter module. If no additional program is executed in this washing program, the number of times the filter module is used remains unchanged.

Therefore, the number of times a filter module is used reflects the total amount of filtered impurities collected therein. The washing equipment obtains the number of times the filter module is used, and can estimate the accumulation of filter impurities in the filter module. When the number of uses reaches the preset number, the corresponding filter module is generally blocked to a certain extent, and the user needs to manually clean it to ensure the filtering effect of the additional program when running the subsequent washing program.

In the solution of this embodiment, the washing equipment is provided with a detection device for detecting whether the filter module is taken out. When the cumulative number of uses of the filter module of the washing equipment reaches the preset number, if the detection device detects that the filter module has been taken out, it will automatically control the number of uses of the filter module to be cleared. In this embodiment, the preset number of times can be set according to the actual capacity of the filtering module, for example, it can be set to 10 to 30 times, preferably 20 times.

Through the above method, when the number of continuous uses of the filter module reaches the preset number, if the detection device determines that the filter module has been taken out, it means that the user has taken out the filter module and cleaned it. In this case, the washing equipment can automatically control the number of uses of the filter module to zero, that is, when the washing program is run again, the number of uses of the filter module will be re-accumulated from zero, which exactly corresponds to the actual state of no filtered impurities collected in the filter module. . In this way, it is avoided that the washing equipment cannot directly detect the accumulation of filter impurities in the filter module. After the user takes out the filter module and cleans it, it still determines that the filter impurities in the filter module are excessively accumulated, which may trigger a false alarm.

In a further solution of this embodiment, a trigger part is provided on the filter module, and the trigger part triggers the detection device when the filter module is taken out. When the number of uses of the filter module reaches the preset number, if the washing equipment receives a signal that the detection device is triggered, it will determine that the filter module has been taken out, that is, the number of uses of the filter module will be cleared to zero.

In this embodiment, when the number of uses of the filter module reaches the preset number, if the detection device detects that the filter module has not been taken out, the current number of uses of the filter module is maintained.

Specifically, in a preferred solution of this embodiment, when the number of uses of the filter module reaches a preset number of times, if the detection device detects that the filter module has not been taken out, that is, the signal that the detection device is triggered has not been received, then no Respond to the start command of the washing program, or do not execute additional programs during the washing program.

In the above solution, if the detection device detects that the filter module has not been taken out, it means that the user has not cleaned the filter module. At this time, since the cumulative number of uses of the filter module has reached the preset number, there is a high probability that a large amount of dust has accumulated in the filter module. Filter out impurities and it may not be possible to perform additional programs in the wash program. In this case, when the user issues the startup execution of the washing program to the washing equipment, the washing equipment does not run the washing program, or does not execute additional programs during the running of the washing program, ensuring that the filter module will not continue to be used. In this way, it is possible to avoid possible operational failures caused by the washing equipment still conducting water to the filter module when the filter module is blocked by filter impurities.

In another preferred solution of this embodiment, when the number of uses of the filter module reaches the preset number, if the detection device detects that the filter module has not been taken out, after the washing program is run again, the washing equipment continues to accumulate the number of uses of the filter module. And based on whether the detection device detects that the filter module is taken out, it controls whether to clear the number of uses of the filter module.

The above solution is suitable for situations where the preset number of times is small. When the cumulative number of uses of the filter module reaches the preset number, a certain amount of filter impurities accumulate in the filter module, but the filtering function of executing additional programs can still be implemented. In this case, if the user does not take out the filter module for cleaning, the washing equipment can still run the washing program and continue to accumulate the number of uses of the filter module. However, after each washing process is completed, the detection results of the detection device will be obtained. If it is detected that the filter module is taken out at a certain time, the number of uses of the filter module will be cleared to zero.

In a further preferred solution of this embodiment, after each washing device completes a washing program, the current number of uses of the filter module is compared with the preset number of times. If it is determined that the number of uses of the filter module is greater than or equal to the preset number of times, the washing equipment will issue a prompt message to remind the user to manually clean the filter module.

The way in which the washing equipment issues prompt information includes: the washing equipment emits an alarm sound such as a buzzer, or the washing equipment emits a reminder voice in the form of a voice broadcast that the filter module needs to be manually cleaned.

It is difficult for users to accurately remember the cumulative number of uses of the filter module, and the filter module is installed inside the washing equipment, and users cannot directly observe the accumulation of filtered impurities in it. When the washing equipment of this embodiment obtains the number of uses of the filter module and determines that it reaches or exceeds the preset number of times, it actively sends out a prompt message that the filter module needs to be cleaned manually, which can prevent the user from forgetting to clean the filter module and causing the washing equipment to fail. The problem is that it cannot be used properly or the washing effect is not good.

In a further solution of this embodiment, after the number of uses of the control filter module is cleared, it also includes:

The washing equipment receives the user's instruction for setting the number of times of continued use and determines the number of times that the filter module can be used;

Get the number of times the filter module is used;

It is judged that the number of times of use of the filter module reaches the stated number of times of continued use, and the washing equipment issues a prompt message;

If the detection filter module is taken out, the number of uses of the control filter module is cleared.

When the accumulated number of uses of the filter module of the washing equipment reaches the preset number, the user takes out the filter module to view it, and the washing equipment controls the number of uses of the filter module to be cleared. However, if the clothes that the user has washed recently have less lint, the current status of the filter module may still be sufficient, and the washing equipment can use the filter module to continue to perform additional functions of filtering. In this case, for the sake of operational convenience, the user may directly install the filter module back into the washing equipment without cleaning it.

However, the washing equipment has cleared the number of uses of the filter module. Under normal circumstances, the washing equipment will only issue a prompt message to clean the filter module when the number of uses of the filter module reaches the preset number again. However, a certain amount of filter impurities have accumulated in the filter module. Before the number of uses reaches the preset number of times again, the filter module may no longer be usable. If the user cannot clearly remember the actual number of uses of the filter module, the problem that the additional program cannot continue to be executed due to the blockage of the filter module during the operation of the washing equipment may occur.

In order to avoid the above problems, the washing equipment of this embodiment provides a function for the user to manually set the number of times that the filter module can be used continuously. After the washing equipment clears the number of uses of the filter module, if the user checks the filter module to determine that it can continue to be used, he can manually set a number of times that can be used so that the washing equipment can re-accumulate the number of uses of the filter module to the stated limit. When the number of uses continues, the user is reminded to clean up.

Through the above method, users do not need to manually clean the filter module every time the washing equipment clears the number of uses of the filter module. Instead, users can manually set a number of continued uses when the filter module is not being cleaned, so that the washing The device will issue a reminder again when the cumulative number of uses of the filter module reaches the stated number of continued uses, making it more convenient to use.

In a first specific solution of this embodiment, a continuous use number setting key is set on the control panel of the washing equipment, and the number of times setting instructions include the number of times the continued use number setting key is triggered. After the detection device detects that the filter module has been reset, it determines the number of times the filter module can continue to be used based on the number of times the continued use setting key is received.

After the user checks the filter module and determines that no cleaning is required, the user reinstalls the filter module on the washing equipment, and then presses the continued use setting button to set the number of continued uses. For example, after the user resets the filter module and continuously presses the continued use setting button 5 times, the washing equipment determines that the number of continued uses of the filter module is 5. When the washing equipment re-accumulates the number of uses of the filter module to 5 times, a prompt message will be issued.

Preferably, the control panel is also provided with a confirmation key. After the washing equipment receives a signal that the continued use setting key is triggered multiple times in a row, if it receives a signal that the confirmation key is triggered, it determines the user's settings. At the end of the process, count the number of continued uses and calculate the total number of times the setting key is triggered as the number of times that can be continued used.

Or, after the washing equipment receives a signal that the continuation count setting button is triggered multiple times in succession, if it does not receive a signal that the continuation count setting button is triggered again within a set time, for example, 10 seconds, it determines the user's settings. At the end of the process, count the number of continued uses and calculate the total number of times the setting key is triggered as the number of times that can be continued used.

In the second specific solution of this embodiment, a usage number selection knob is provided on the control panel of the washing equipment. The number of times setting instructions include the stop rotation position of the number of times of use selection knob. After the detection device detects that the filter module has been reset, if it receives a signal that the number of uses selection knob is triggered, it determines the number of times the filter module can continue to be used based on its final stop rotation position.

Preferably, the number of uses selection knob can be pressed. After the user resets the filter module, he first presses the number of uses selection knob, and the washing equipment determines that the user has set the number of continued uses, and then further determines the number of continued uses based on the stop rotation position of the number of uses selection knob. When the current stop position of the number selection knob corresponds to the number of times that the user wishes to set, the user only presses the number selection knob without further rotation.

In the third specific solution of this embodiment, the washing equipment receives the voice command issued by the user and analyzes it to determine the number of times the filter module can be continued to be used.

In detail, after the user resets the filtering module, he or she can dictate a voice command such as "Continue to use the filtering module 5 times." The washing equipment performs keyword extraction on the voice command, extracts "filter module", "continue" and "5 times", and determines that the voice command is used for setting The number of times the filter module can be used continuously is set to 5 times.

In the preferred solution of this embodiment, when the washing equipment re-accumulates the number of uses of the filter module to the number of times of continued use set by the user, if the detection device detects that the filter module has been taken out, it controls the number of times of use of the filter module to be cleared. And if the detection device detects that the filter module has not been taken out, the control cannot execute the washing process. Since the filter module has been used many times without cleaning at this time, there is a high probability that it no longer has the ability to be used. Therefore, the washing equipment no longer runs the washing program and waits for the user to clean the filter module.

Further, after the number of times of use of the filter module reaches the number of times of continued use set by the user, and the number of times of use of the filter module has been controlled to be cleared, the washing equipment automatically resets the number of times of use of the filter module. That is, during the subsequent operation of the washing equipment, when the obtained number of uses of the filter module reaches the preset number, a prompt message will be sent, and it will be detected whether the filter module has been taken out, and whether to clear the number of uses of the filter module.

In a further solution of this embodiment, when it is determined that the number of uses of the filter module is less than the preset number, if the detection device detects that the filter module has been taken out, the current number of uses of the filter module is maintained.

When the number of uses of the filter module does not reach the preset number, since the washing equipment does not alarm, the user takes out the filter module voluntarily to check the current status of the filter module. At this time, the filter module can most likely continue to be used. In most cases, users will not clean it manually, but will reset the filter module and install it back into the washing equipment. Therefore, the washing equipment will not automatically clear the number of uses in this case, ensuring that the user can be accurately reminded to clean the filter module during subsequent operations.

Further, when it is determined that the number of uses of the filter module is less than the preset number, if the washing equipment receives a user's instruction to clear the number of uses, it controls the number of uses of the filter module to be cleared.

In the above solution, the washing equipment provides the user with the function of manually controlling the number of uses to zero. When the number of uses of the filter module does not reach the preset number, if the user removes the filter module and finds that more filter impurities have accumulated, he can also Choose to clean the filter module directly and then manually control the usage count to zero. Especially when the user views the filter module, if the current number of uses is close to the preset number, for example, 2 to 3 times less than the preset number, the user can also directly clean the filter module and manually clear it after the cleaning is completed. There is no need to reinstall the filter module. When the cumulative number of uses reaches the preset number, take out the filter module again to complete cleaning.

Solutions to realize user manual control of clearing the usage count may include the following.

Option 1: A clear key is set on the control panel of the washing equipment, and the clearing instruction for the number of uses is triggered by the clear key. When the number of uses of the filter module is less than the preset number, if the washing equipment receives a signal that the clear key is triggered, it controls the number of uses of the filter module to be cleared.

Option two, the usage count clearing instruction is that two or more specific keys on the control panel are triggered according to the set rules. For example, the start/pause key and the start/stop cycle key are triggered at the same time, or the common program key, wool program key and chemical fiber program key are triggered in sequence. By triggering multiple specific buttons at the same time or sequentially to clear the usage count, it can effectively prevent users from accidentally touching the reset button, or children at home accidentally touching the washing equipment and causing the filter module to reset the usage count.

Option 3: The washing equipment receives and analyzes the voice command issued by the user, determines that the voice command is used to clear the number of uses of the filter module, and then controls the number of uses of the filter module to be cleared. For example, the user dictates the voice command "clear the number of uses of the filter module", and the washing equipment extracts keywords from the voice command, and extracts "filter module", "number of uses" and "clear", then controls the use of the filter module The times are cleared to zero. The voice control method does not require adding function buttons or other controls on the control panel, and is easy to use.

In another solution of this embodiment, the filter module includes a detachably installed lint collection component for collecting filter impurities. Specifically, the filter module further includes a housing, which is push-pullably installed on the washing equipment, and the lint collection assembly is detachably installed inside the housing.

The filter module is provided with a detection element for detecting whether the lint collection assembly is removed, and the detection element may be a contact switch. The wire scrap collection component is installed in the housing, contacts the contact switch to make it conductive, the wire scrap collection component is removed, separated from the contact switch, and the contact switch is disconnected. Whether the wire scrap collection component has been removed can be judged by the on-off status of the contact switch.

When the number of uses of the filter module is less than the preset number, if the detection device detects that the filter module is pulled out, it determines whether the lint collection assembly has been removed. When the washing equipment determines that the lint collection component has been removed, it controls the number of uses of the filter module to be cleared. And if the washing equipment determines that the lint collection component has not been removed, the current number of uses of the filter module is maintained.

In the above solution, when the filter module is taken out when the number of uses is less than the preset number, the washing equipment further determines whether the user has removed the lint collection assembly. Since the accumulated filter impurities are collected in the lint collection component, if it is detected that the lint collection component has been removed, there is a high probability that the user has removed the lint collection component and cleaned it. At this time, the washing equipment automatically determines the number of times the filter module has been used. Clear, After running the washing program again, the number of uses of the filter module will be accumulated again from zero.

However, if the detection filter module is pulled out but the lint collection component has not been removed, it means that the user has not cleaned the lint collection component and may have just pulled it out to check the accumulation of filter impurities. At this time, the washing equipment does not clear the number of uses of the filter module. After running the washing program again, it will continue to accumulate the number of uses of the filter module on the current basis.

As for the situation where the number of uses of the filter module reaches or exceeds the preset number of times, as long as the detection device detects the filter module, that is, after the housing is pulled out, the number of uses of the filter module will be cleared to zero.

In this embodiment, the washing equipment is set with a preset number of times for the number of uses of the filter module, and the number of times of use of the filter module is accumulated with each run of the washing program. When the cumulative number of uses reaches the preset number, a prompt message can be sent to remind the user to clean the filter module to prevent the user from forgetting to clean the filter module and affecting the implementation of the subsequent filtering function. At the same time, when the user takes out the filter module for cleaning, the detection device can detect that the filter module has been taken out, and then automatically control the number of uses of the filter module to be cleared. When the user reinstalls the cleaned filter module into the washing equipment, the washing equipment will re-accumulate the usage times of the filter module from scratch, so that the accumulated usage times of the washing equipment can match the actual usage status of the filter module, avoiding the need for users to clean the filter module. If you later forget to clear the accumulated number of uses, false alarms may be triggered during subsequent use.

Embodiment 33

As shown in Figure 31, this embodiment is a further limitation of the above-mentioned Embodiment 32. After it is determined that the number of times the filter module has been used has reached the preset number, and it is detected that the filter module has been taken out, if a confirmation clearing instruction from the user is received, Then the usage count of the control filter module is cleared.

Further, if the user's confirmation clearing instruction is not received after the detection filter module is taken out, the current number of uses of the filter module is maintained.

And if after judging that the number of uses of the filter module reaches the preset number, the user's confirmation clearing instruction is received, but it is always detected that the filter module has not been taken out, the current number of uses of the filter module is also maintained.

In the above solution, the washing equipment sets up a double judgment logic for clearing the number of uses of the filter module. Only when it is detected that the filter module is taken out and the user triggers the confirmation clearing command, the clearing of the number of uses of the filter module is controlled. If the filter module is taken out, or if either of the two conditions of the user triggering the clearing instruction is not met, the number of uses will not be cleared, but the current number of uses of the filter module will be maintained.

In this embodiment, the way for the user to confirm clearing may specifically include the following.

The first specific solution is to add a clear key on the control panel of the washing equipment, and the confirmation clear command means that the clear key is triggered.

The washing equipment sends a prompt message when it determines that the number of uses of the filter module reaches the preset number. After the user takes out the filter module and touches the reset button, the washing equipment controls the number of times of use of the filter module to be cleared. The user can also touch the reset button to confirm the reset before or after installing the filter module back into the washing equipment after taking out the filter module and completing manual cleaning.

In the second specific solution, the confirmation clearing instruction is that two or more specific buttons on the control panel are triggered according to the set rules. For example, the start/pause key and the start/stop cycle key are triggered at the same time, or the common program key, wool program key and chemical fiber program key are triggered in sequence.

When the washing equipment determines that the number of uses of the filter module reaches the preset number, the user receives a prompt message from the washing equipment and takes out the filter module. The user can then issue a confirmation clearing instruction by triggering multiple specific buttons at the same time or in sequence, and the washing equipment controls the number of uses of the filter module to be cleared.

In the third specific solution, the washing equipment receives the voice command issued by the user and analyzes it. If the analysis result is a confirmation of clearing, the number of uses of the filter module is cleared.

The washing equipment determines that the number of uses of the filter module has reached the preset number, and sends a prompt message to the user. The user can take out the filter module at this time. If the user checks the filtering module and determines that manual cleaning is required, he or she can dictate a voice command immediately or after completing the manual cleaning, such as "Reset the number of uses of the filtering module." The washing equipment performs keyword extraction on the voice command and obtains the keywords "filter module", "number of uses" and "clear". It determines that the voice command corresponds to the confirmation clearing command, and controls the clearing of the number of uses of the filter module.

In this embodiment, when the number of uses of the filter module reaches the preset number, the washing equipment will only control the number of times of use of the filter module to be cleared when it detects that the filter module has been taken out and receives a confirmation clearing instruction from the user. By setting up double judgment logic, it avoids the situation where the washing equipment mistakenly performs automatic clearing when the user takes out the filter module to view it without performing manual cleaning. At the same time, the washing equipment will not be cleared when only the confirmation clearing command is triggered, which prevents the user from accidentally touching the button or causing other misoperations. The washing equipment does not perform manual operation in the filter module. The problem of clearing the usage count when cleaning.

Embodiment 34

As shown in Figures 1 and 11, this embodiment provides a washing equipment, and the control method of the washing equipment described in the above-mentioned Embodiment 32 or 33 can be applied.

Specifically, the washing equipment includes:

Water container 100;

The circulation filter pipeline has its water inlet end and water outlet end connected to each other respectively, and a circulation pump 400 is arranged on it;

The filtering device 600 is provided on the circulating filtering pipeline and has a sewage outlet 6103 for discharging sewage outward;

The recovery device 500 and the sewage outlet 6103 of the filtering device 600 are used to receive the sewage discharged from the filtering device 600 and collect the filtered impurities carried in the sewage.

In this embodiment, the operation of the washing equipment to perform additional programs in the washing program specifically includes: the circulation pump 400 works to guide water to the filter device 600 for filtering, and the filter device 600 discharges sewage into the recovery device 500 according to the set program. operate.

The filter module described in the thirty-second and thirty-third embodiments can be any one of the filter device 600 and the recovery device 500 in this embodiment.

Specifically, at least one of the filtering device 600 and the recovery device 500 is configured to be removably installed on the washing equipment. The washing equipment accumulates the number of uses of the filter device 600/recycling device 500 as the washing program runs, and sends a prompt message when the number of uses reaches the preset number. The user can take out the filtering device 600/recycling device 500 for manual cleaning. When the washing equipment detects that the filtering device 600/recycling device 500 has been taken out, the accumulated number of uses will be cleared.

In the specific solution of this embodiment, the filter device 600 is installed inside the washing equipment, and generally the user cannot take it out. The recovery device 500 includes a housing 510 and a lint collection assembly 570 disposed inside the casing 510. The lint collection assembly 570 filters the sewage received by the recovery device 500 and collects filtered impurities in the water. The housing 510 is push-pullably installed on the box 10 of the washing equipment, so that the recovery device 500 can be extracted from the box 10 of the washing equipment.

In this embodiment, the filter module refers to the recovery device 500. The washing equipment accumulates the number of uses of the filter module (ie, the recovery device 500). When the preset number of times is reached and it is detected that the casing 510 of the recovery device 500 is extracted. , control the number of uses of the filter module to be cleared.

Specifically, in this embodiment, a recovery chamber is formed inside the recovery device 500, and the upper side of the housing 510 is provided with an open structure. The wire scrap collection assembly 570 is installed at a certain height inside the housing 510 to divide the recovery chamber into a first chamber 531 and a second chamber 532 distributed up and down.

The lint collection assembly 570 may be a horizontally arranged frame and a filter screen laid on the frame. The sewage outlet 6103 of the filter device 600 is connected to the first chamber 531. The sewage carrying filtered impurities enters the first chamber 531, is filtered by the filter of the lint collection assembly 570, and then enters the second chamber 532. The filtered impurities are collected in the first chamber 531. In the chamber 531 , that is, it is collected on the upper surface of the lint collection component 570 .

The lint collection assembly 570 is detachably installed inside the casing 510. When the user pulls the casing 510 out of the box 10, the lint collection assembly 570 can be removed from the casing 510 through the opening on the upper side of the casing 510. Remove and remove for manual cleaning.

The box 10 of the washing equipment is provided with an accommodation cavity for accommodating the recovery device 500, and a detection device is arranged in the accommodation cavity. When the user withdraws the recovery device 500 from the accommodation cavity, the detection device is triggered, and the washing equipment can determine that the recovery device 500 has been withdrawn.

Through the setting of the switching device 270, the washing equipment can realize two filtration functions: circulation filtration during the washing process and drainage filtration during the drainage process by arranging a filtering device 600 in the washing equipment. At the same time, circulation filtration and drainage filtration share the circulation pump 400 and part of the pipeline structure, which simplifies the waterway control structure inside the washing equipment. By controlling the conduction direction of the switching device 270, the function switching between circulation filtration and drainage filtration can be realized, and the control logic is simple. Moreover, the drainage water from the washing equipment also needs to pass through the filter device 600 before being discharged to ensure that This ensures that microplastics will not be carried in the drainage water flow, further avoiding the problem of microplastics entering the ecological cycle.

In this embodiment, the washing equipment is provided with a filtering device 600 for filtering the water in the water tank 100. The filtering device 600 has a self-cleaning function and does not require manual cleaning by the user.

When the accumulated number of uses of the recycling device 500 is less than the preset number, the user can also pull out the recycling device 500 to check the accumulation of filtered impurities on the lint collection assembly 570 . If a large amount of filtered impurities has accumulated, the user can also choose to clean the lint collection assembly 570 directly, and actively control the washing equipment to clear the number of uses of the recovery device 500 through buttons or voice, and the washing equipment runs the washing program again. After the end, the number of uses of the recycling device 500 will be accumulated again from zero.

Embodiment 35

As shown in FIG. 1 and FIG. 32 to FIG. 37 , the difference between this embodiment and the above-mentioned Embodiment 34 is that the recovery device 500 is integrated with the detergent dispensing device 300 of the washing equipment.

Specifically, the detergent dispensing device 300 is installed on the box 10 of the washing equipment and includes a fixed sink 310 . The recovery device 500 includes a lint collection assembly 570 disposed inside the sink 310 . The water tank 310 is provided with a discharge port 302, and the discharge port 302 is connected to the water tank 100 through a pipeline. After the sewage discharged from the filtering device 600 is filtered by the lint collection assembly 570, the water with the filtered impurities removed can be discharged into the sink 310, and enters the water tank 100 through the discharge port 302, for use in the subsequent washing process of the washing equipment, or along with the washing equipment. of drainage water is discharged.

In a further solution of this embodiment, an insertable/extractable dispenser box 340 is provided inside the water tank 310. The water tank 310 is extended along the insertion/extraction movement direction of the dispenser box 340, and the left end is open for the dispenser box 340 to extend outward. Right end closed setting. The dispenser box 340 is formed with a detergent adding cavity 341 and a recovery installation cavity 342 that are isolated from each other. The detergent addition cavity 341 and the recovery installation cavity 342 are independently connected to the sink 310 . The lint collection assembly 570 is installed in the recovery installation cavity 342 .

The user pulls out the dispenser box 340 and puts the detergent to be added into the detergent adding chamber 341 . During the water inflow process of the washing equipment, the incoming water flow can be mixed with the detergent in the detergent adding chamber 341 and enter the water tank 310, and then be put into the water tank 100 through the discharge port 302.

In the above solution, the front end of the dispenser box 340 is provided with a handle 345 for the user to grasp, and the lint collection assembly 570 can be inserted into/out of the sink 310 along with the dispenser box 340 . When it is necessary to clean the lint collection assembly 570, the user can pull out the distributor box 340, and then remove the lint collection assembly 570 from the recovery installation cavity 342 for cleaning, which is easy to operate.

The detergent adding cavity 341 and the recovery installation cavity 342 are respectively provided on both sides of the dispenser box 340 and extend along the direction in which the dispenser box 340 is pulled. The lint collection assembly 570 is installed in the end of the recycling installation cavity 342 close to the distributor box 340 inserted into the water tank 310 (ie, the right end in FIG. 35 ).

The upper side of the detergent adding cavity 341 and the recycling installation cavity 342 are open. The opening of the detergent adding cavity 341 is used for the user to add detergent therein, and the opening of the recycling installation cavity 342 is used for installing/disassembling lint collection. Component 570. Since the opening of the detergent adding chamber 341 extends from the right end to the left end of the dispenser box 340, the user does not need to completely withdraw the dispenser box 340 when adding detergent, but only needs to move the opening of the detergent adding chamber 341 close to the dispenser. The water tank 310 can be extracted from a part of the left end of the box 340.

In this embodiment, a detection device 350 is provided inside the water tank 310 for detecting whether the recovery device 500 , that is, the lint collection assembly 570 is extracted along with the dispenser box 340 . It can be seen that when the user pulls out the dispenser box 340 to add detergent, the dispenser box 340 does not need to be completely pulled out, and the lint collection assembly 570 is not pulled out to the outside of the sink 310 at this time.

If the lint collection assembly 570 needs to be removed for cleaning, the dispenser box 340 needs to be pulled out to a greater distance than when adding detergent, so that the lint collection assembly 570 can be pulled out to the outside of the sink 310 along with the dispenser box 340. .

Specifically, when the dispenser box 340 is drawn out to a set distance, a portion of the opening of the detergent adding chamber 341 near the left end of the dispenser box 340 has been drawn out of the water tank 310, and the operation of adding detergent can be realized. In this embodiment, the set distance may be allocated 1/2~2/3 of the total length of the device box 340.

When the distributor box 340 is pulled out to a distance greater than the set distance, the lint collection component 570 is pulled out to the outside of the water tank 310 along with the distributor box 340, and the user can check the status of the filtered impurities collected in the lint collection component 570. , and the lint collection assembly 570 can be taken out for manual cleaning.

The detection device 350 can detect the distance from which the dispenser box 340 is extracted from the water tank 310. When the distance is greater than the set distance, it is determined that the recovery device 500 has been extracted.

Therefore, in this embodiment, when the washing equipment determines that the number of uses of the recovery device 500 has reached the preset number, and if the detection device 350 detects that the distance between the dispenser box 340 and the water tank 310 is greater than the set distance, the filter module is controlled. Clear the number of uses, or control the number of uses of the filter module to clear after further receiving the user's confirmation clearing instruction.

In another solution of this embodiment, the detection device 350 is disposed near the open end of the water tank 310, and is triggered when the right end of the dispenser box 340 passes by the detection device 350. The washing equipment receives a signal that the detection device 350 is triggered, indicating that the right end of the dispenser box 340 has been pulled to a position close to the open end of the sink 310, and the lint collection assembly 570 has been pulled out of the sink 310 along with the dispenser box 340.

When the cumulative number of uses of the recycling device 500 in the washing equipment reaches the preset number, if a signal that the detection device 350 is triggered is received, the number of uses of the filter module is controlled to be cleared, or after further receiving a confirmation clearing instruction from the user Control the number of uses of the filter module to be cleared.

Furthermore, in this embodiment, the lint collection assembly 570 specifically includes a filter bracket 573 and a filter screen. The filter bracket 573 forms a relatively closed filter cavity for receiving sewage discharged from the filter device 600 . The filter bracket 573 is provided with a sewage inlet 574 and a plurality of water outlets 572. The filter screen at least covers the water outlets 572 for filtering the received sewage.

The sewage discharged from the filter device 600 enters the filter cavity formed by the filter bracket 573 through the sewage inlet 574, and can only flow out through the filter screen covering the water outlet 572, ensuring the filtering effect to the greatest extent, and there will be no sewage. After passing through the filter, it enters the water tank 310.

The water outlet 572 is provided on the upper surface of the filter bracket 573. The filtered water flows out from the water outlet 572 located on the upper surface of the filter bracket 573, and is collected in the recovery installation cavity 342, and finally overflows from the recovery installation cavity 342 into the sink. 310, thus flowing into the water tank 100.

In the preferred solution of this embodiment, water outlets 572 are provided on the upper and lower surfaces of the filter bracket 573. The incoming sewage can be filtered by the filter from both the upper and lower sides and flow out, which improves the filtration of sewage by the lint collection assembly 570. efficiency.

In this embodiment, a sewage inlet 301 connected to the sewage outlet 6103 of the filter device 600 is provided at the right end of the water tank 310 , and the sewage inlet 574 of the filter bracket 573 is provided at the right end of the distributor box 340 . When the lint collection assembly 570 is inserted into the sink 310 along with the distributor box 340, the sewage inlet 574 is sealed with the sewage inlet 301. The lint collection assembly 570 is extracted from the water tank 310 along with the distributor box 340, and the sewage inlet 574 is separated from the sewage inlet 301.

In a specific solution of this embodiment, when the lint collection assembly 570 is inserted into the sink 310 along with the distributor box 340, the sewage inlet 574 is inserted into the sewage inlet 301. A sealing structure is provided on the outer wall of the sewage inlet 574 and/or the inner wall of the sewage inlet 301 to achieve a sealed connection between the two. Then the sewage discharged by the filter device 600 can flow from the sewage inlet 301 to the sewage inlet 574 and enter the filter formed by the filter bracket 573 In the cavity, there will be no water leakage problem at the connection between the sewage inlet 574 and the sewage inlet 301. When the lint collection assembly 570 is extracted from the water tank 310 along with the distributor box 340, the sewage inlet 574 is extracted from the sewage inlet 301, and there is no longer communication between the two.

In another specific solution of this embodiment, the sewage inlet 301 extends toward the inside of the sink 310 to form a plug-in portion. When the lint collection assembly 570 is inserted into the sink 310 along with the distributor box 340, the sewage inlet 574 is sleeved on the plug-in portion. . A sealing structure is provided on the inner wall of the sewage inlet 574 and/or the outer wall of the plug-in part to achieve a sealed connection between the two. Then the sewage discharged from the filter device 600 can flow from the sewage inlet 301 to the sewage inlet 574 and enter the filter formed by the filter bracket 573. In the cavity, there will be no water leakage problem at the socket between the sewage inlet 574 and the plug-in part. When the lint collection assembly 570 is pulled out from the water tank 310 along with the distributor box 340, the plug-in part is pulled out from the sewage inlet 574, and there is no longer communication between the two.

In this embodiment, the recovery device 500 is integrated with the detergent delivery device 300, making full use of the space inside the sink 310. There is no need to reserve additional space for the installation of the recovery device 500 inside the washing equipment, so that the internal structure of the washing equipment More compact, it is conducive to the miniaturization design of washing equipment.

Embodiment 36

The difference between this embodiment and the above-mentioned Embodiment 34 is that there is no recovery device in the washing equipment, and the filtering device connected to the water tank is removably installed on the washing equipment. When the washing equipment is working, water is directed to the filter device through the circulating pump, and the filtered water can be Return to the water tub, or drain the washing machine. The filtered impurities filtered out during filtration are collected inside the filter device, and the user can remove the filter device from the washing equipment for manual cleaning.

In this embodiment, the operation of the washing equipment to perform an additional program in the washing program only includes: turning on the circulation pump according to the set program, and conducting water to the filtering device for filtration.

In this embodiment, the specific structure of the filtering device may be similar to the recovery device in Embodiment 34, including a housing that is push-pullably installed on the washing equipment box, and an internal lint collection assembly. The water in the water tank is introduced into the housing, filtered through the thread collection assembly, and the filtered impurities are collected on the upper side of the thread collection assembly.

In this embodiment, the washing equipment obtains the number of uses of the filter module, where the "filter module" refers to the filter device. When the number of uses of the filter module reaches the preset number, if it is detected that the filter device is extracted, the control is executed to clear the number of uses of the filter module.

The washing equipment of this embodiment is directly provided with a filtering device that can be taken out from the washing equipment. The filtering device no longer performs self-cleaning. Instead, the user takes the filtering device out of the washing equipment for manual cleaning. The washing equipment accumulates the number of times the filter device has been used, and when it determines that the preset number of times has been reached, a prompt message is issued to remind the user to clean the filter device. At the same time, when the user pulls out the filter device, the detection device can be triggered, and the washing equipment automatically controls the number of uses to be cleared, so that when the washing program is run again, the number of uses of the filter device can be re-accumulated.

It can be understood that, similar to Embodiment 34, the washing equipment can also be configured such that after the detection device detects that the filter device is extracted, and after receiving the user's confirmation clearing instruction, the washing equipment controls the number of uses to be cleared. If the confirmation clearing instruction is not received, the current number of uses is maintained. Through the user's secondary confirmation, it is avoided that the washing equipment mistakenly clears the number of uses when the user takes out the filter device to check but does not actually clean it manually.

Embodiment 37

As shown in Figure 1, Figure 11, and Figure 32 to Figure 37, this embodiment is a further limitation of any one of the above-mentioned Embodiments 32 to 36. The filtering capability of the filter module is defined as: The number of times it can be used in its current state until it is clogged by filter impurities. Among them, each time the washing equipment performs an additional washing program operation, it is recorded as a use of the filter module. When programming the washing equipment, determine the specific value of the preset times based on the initial filtration capacity of the filtration module.

The initial filtration capacity of the filtration module is at least 10 to 30 times, preferably 15 to 25 times. For example, the initial filtering capacity of the filter module is at least 20 times. That is to say, when there is no accumulation of filter impurities in the filter module, such as when the user has just completed manual cleaning of the filter module, the filter module can at least continuously run. The additional program can be fully executed in the 20 wash programs without clogging failure.

Taking the initial filtering capability of the filtering module as 20 times as an example, the corresponding preset number of times is set to 20. The washing equipment will accumulate the number of uses of the filter module after running the washing program. When a washing program is completed and the accumulated number of uses is exactly 20 times, the washing equipment will issue a prompt message. After receiving the prompt message, the user takes out the filter module and performs manual cleaning. At this time, the detection device 350 can detect that the filter module has been taken out, and the washing equipment controls the number of uses of the filter module to be cleared. That is to say, the number of uses of the filter module currently recorded by the washing equipment is cleared. After running the washing program again, if additional programs are executed, the accumulated number of uses of the filter module will be 1.

In a further solution of this embodiment, a filtering device 600 and a recovery device 500 are provided in the washing equipment. The filter module refers to the recovery device 500.

By filtering the washing water and washing equipment drainage through the filtering device 600, impurities with a size greater than 50 μm can be filtered out, and the filtered impurities may include microplastics. In particular, the filtered impurities may include plastic fibers with a length greater than 50 μm and a diameter of 10 to 1000 μm. Preferably, the plastic fiber has a length of 400 to 600 μm, and the most common length in the distribution is 500 μm ± 50 μm. Furthermore, the diameter of these plastic fibers is preferably 10 to 50 μm, with the most common having a diameter of 17 μm ± 2 μm.

In this embodiment, by conducting a large number of tests on different types of clothes and different washing procedures in advance, it is found that the mesh number of the filter screen in the lint collection assembly 570 and the mesh number of the filter screen in the filter device 600 are set within the above range. , the plastic fibers of the above sizes can be filtered out from the washing water and washing equipment drainage, and finally the microplastic particles accounting for more than 80% of the total content in the water can be collected in the recycling device 500, so that In the end, the content of microplastics in the drainage water of the washing equipment dropped significantly and was able to meet the direct discharge standards.

In this embodiment, as the number of uses increases, the total amount of filter impurities collected in the recovery device 500 gradually increases, and the lint collection component 570 is gradually covered by the filter impurities. The filter impurities block the mesh on the filter and cause lint. The collection component 570 cannot realize the filtering function of sewage, and eventually the filtering capacity of the filtering module is exhausted.

In this embodiment, a large number of tests are conducted on different types of clothes and different washing procedures in advance, and the structure of the lint collection component 570 is adjusted to change the maximum amount of filtered impurities it can collect, so that the recovery device 500 can operate without manual operation by the user. Under the premise of cleaning, additional programs can be completely executed during at least 10 to 30 consecutive washing programs, ensuring a user-friendly experience.

The above are only preferred embodiments of the present invention, and do not limit the present invention in any form. Although the present invention has been disclosed above in preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology of this patent Without departing from the scope of the technical solution of the present invention, personnel can make some changes or modify the above-mentioned technical contents into equivalent embodiments with equivalent changes. In essence, any simple modifications, equivalent changes and modifications made to the above embodiments still fall within the scope of the present invention.
