Description

Filtering module

Technical Field

The utility model belongs to the technical field of the washing equipment, specifically speaking relates to a filter module.

Background

Washing apparatuses for washing laundry, such as washing machines, cause lint to fall off and be mixed into washing water during washing of the laundry due to friction between the laundry and the laundry, and between the laundry and the washing machine itself. If the lint in the washing water cannot be removed, the lint is likely to adhere to the surface of the laundry after the washing is completed, which may affect the washing effect of the laundry. For this reason, a conventional washing machine is provided with a filter for filtering lint, and the lint is removed from the washing water by continuously passing the washing water through the filter during washing.

However, the filtered impurities such as the filtered thread scraps are accumulated in the filter, and the filter is clogged for a long time, thereby failing to realize the filtering function. The filter is generally installed inside the washing machine, so that a user cannot directly observe the accumulation of filtered impurities in the filter, and only can clean the filter regularly. However, if the user has a large amount of thread and scraps of the laundry within a period of time or forgets to clean the filter for a long time, the filter may be clogged. At this time, if the user uses the washing machine to wash the laundry, since the filter cannot perform a filtering function, the washing effect of the laundry may be affected.

In recent years, the concept of micro plastic has been proposed in the field of environmental protection and gradually receives increasing attention. Research has found that an important source of micro-plastics is waste water from domestic washing machines. The reason is that with the popularization of chemical fiber fabrics, the clothes fiber dropped off in the washing process is discharged along with the drainage water flow of the washing machine, and then the micro plastic mixed in the natural water environment is formed. The micro-plastics directly enter into ecological cycle along with the drainage water flow, and are finally accumulated in the human body through a natural biological chain, which may affect the human health. For this reason, in some areas relevant standards have been established for the content of micro-plastics in the washing machine effluent. Once the filter cannot be used, the washing machine runs to wash clothes, and thread scraps falling off from the clothes can be directly discharged along with the drainage water flow of the washing machine, so that the problem that a large amount of micro-plastics exist in the drainage water of the washing machine and the drainage standard cannot be met is caused.

In view of this, the present invention is especially provided.

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example one

As shown in fig. 1 and 2, the present embodiment provides a filtering module that can be applied to a washing apparatus to implement a filtering function for water. The washing equipment can be washing equipment with a clothes washing function, such as a washing machine, a washing and drying integrated machine, a nursing machine and the like.

Specifically, the washing device includes a water container 100, and the filtering module of the present embodiment is used for filtering water in the water container 100.

In this embodiment, the filtering module specifically includes a filtering device 600 and a recycling device 500. Wherein, the filtering device 600 is provided with a sewage outlet 6103 for discharging the sewage carrying the filtering impurities. The recycling device 500 is communicated with a sewage outlet 6103 of the filtering device 600 for receiving the sewage discharged from the filtering device 600.

In the above scheme, the filtering device 600 of the filtering module is used for receiving the water in the water containing barrel 100 of the washing equipment for filtering, and the filtering device 600 has certain self-cleaning capability, so that the filtering impurities accumulated in the filtering process can be discharged into the recovery device 500, and the filtering efficiency is prevented from being influenced by the accumulation of a large amount of filtering impurities.

The filter module is integrally installed inside the washing equipment, so that a user cannot directly observe the state of the filter module when using the washing equipment, particularly the accumulation condition of filtered impurities in the filter module. Once the filtering impurities are too much, the filtering device 600 may not discharge the sewage to the recycling device 500, and the filtering module may not achieve the filtering function.

For this reason, the filtering module of this embodiment is further provided with a blockage detection device for detecting whether the process of discharging the sewage from the filtering device 600 to the recovery device 500 is blocked. The filtering module may determine whether the process of discharging the sewage from the filtering device 600 to the recycling device 500 is blocked according to the detection result of the blockage detection device.

Through setting up block up detection device, whether filtration module can independently detect sewage discharge process and block up, will block up detection device and washing equipment's control system and be connected, washing equipment just can in time respond when sewage discharge is obstructed. Therefore, the situation that the filtering module is blocked and cannot realize the filtering function due to the fact that the user cannot directly observe the state of the filtering module is avoided.

In a specific aspect of this embodiment, the blockage detection device includes a flow detection device for detecting a flow of the sewage discharged from the filtering device 600. The clogging detecting means determines whether or not clogging occurs in the process of discharging the sewage from the filtering means 600 to the recovering means 500 based on the flow rate of the sewage discharged from the filtering means 600.

Further, the filtering module further includes a sewage draining pipeline 240, a sewage draining outlet 6103 of the filtering apparatus 600 is connected to the water inlet end of the sewage draining pipeline 240, and the water outlet end of the sewage draining pipeline 240 is communicated with the recycling apparatus 500. The flow rate detecting means is a flow meter 243 provided on the sewage line 240.

Specifically, the control method for detecting whether the blockage occurs comprises the following steps:

detecting the flow rate of the discharged sewage in the process of discharging the sewage to the recovery apparatus 500 by the filtering apparatus 600;

if it is detected that the flow rate of the sewage discharged from the filtering apparatus 600 is lower than the preset flow rate, it is determined that the process of discharging the sewage from the filtering apparatus 600 to the recycling apparatus 500 is blocked.

When the filtering module is in a normal working state, the filtering device 600 discharges sewage into the recovery device 500, and the flow rate of the discharged sewage can be maintained at a certain level. However, when the following occurs, the flow rate of the discharged sewage is decreased.

In the first case, when the inside of the filtering apparatus 600 is blocked due to accumulation of a large amount of filtering impurities, or when the filtering impurities are accumulated and blocked in a part of the sewage discharging pipeline 240, the sewage is blocked from being discharged into the recycling apparatus 500 through the filtering apparatus 600, and thus the flow rate of the sewage is reduced. When the washing device detects that the flow rate of the sewage is reduced to be lower than the preset flow rate, it indicates that the filtering device 600 or the sewage discharge pipeline 240 is blocked, and the sewage cannot be discharged.

In the second case, the lint collecting assembly 570 is disposed in the recycling device 500 of this embodiment, so as to divide the recycling device 500 into a first chamber 531 and a second chamber 532 which are distributed vertically. The water outlet end of the sewage discharging pipeline 240 is communicated with the first chamber 531, sewage carrying filtered impurities enters the first chamber 531, the sewage enters the second chamber 532 after being filtered by the filter screen of the thread scrap collecting assembly 570, and the filtered impurities are collected in the first chamber 531, namely, on the upper side surface of the thread scrap collecting assembly 570. Recovery unit 500 can separate out filtering impurity from the sewage that it received through line bits collection component 570, and convenience of customers directly handles filtering impurity of collection, has avoided filtering impurity to mix in aqueous, can't carry out the condition of effective processing to it.

However, when the lint collecting unit 570 of the recycling apparatus 500 is clogged by the filtered foreign substances, the filtering of the received sewage cannot be performed. The waste water cannot enter the second chamber 532 through the lint collecting assembly 570 and gradually fills the first chamber 531. When the first chamber 531 is full or nearly full of sewage, the resistance experienced by subsequent sewage entering the recovery device 500 becomes greater. If the process of discharging the sewage from the filter apparatus 600 to the recovery apparatus 500 does not use an additional driving force, but only relies on the gravity of the sewage itself to perform the sewage discharging operation, it is difficult for the sewage to enter the recovery apparatus 500, resulting in a decrease in the flow rate of the sewage.

When the flow rate of the sewage detected by the washing device drops below the preset flow rate, it indicates that the lint collecting assembly 570 is blocked, and the first chamber 531 is close to being filled, and the filter device 600 cannot further discharge the sewage into the recycling device 500.

In the above scheme, the flow rate of the sewage discharged from the filtering device 600 directly reflects the sewage discharge capacity of the filtering device 600 to the recovery device 500, and the detection is an intuitive detection on whether the sewage discharge process is blocked, the detection structure and logic are simple, and the judgment on the blocking condition is accurate.

In a further aspect of this embodiment, the recycling device 500 includes a housing 510, and the lint collecting assembly 570 is installed at a certain height inside the housing 510 for filtering the received sewage and collecting the filtered impurities. The lint collecting assembly 570 may be a horizontally disposed frame and a screen laid on the frame.

When the filter module of this embodiment is installed in the washing apparatus, the housing 510 is insertably/withdrawably installed in the cabinet 10 of the washing apparatus, the upper side of the housing 510 has an opening, and the lint collecting assembly 570 is detachably installed inside the housing 510. When the recycling device 500, especially the lint collecting assembly 570 therein, needs to be cleaned, and the user pulls the housing 510 out of the box 10, the lint collecting assembly 570 can be detached from the inside of the housing 510 through the opening at the upper side of the housing 510 and taken out for cleaning, and at this time, the recycling device 500 does not need to be completely detached, so that the operation is more convenient.

In this embodiment, the specific structure of the filtering apparatus 600 includes:

a filtering cavity 610, on which a water inlet 6101, a filtered water outlet 6102 and a sewage outlet 6103 are arranged;

a filtering mechanism 620 rotatably disposed inside the filtering chamber 610 and having a water outlet 621 rotatably and hermetically connected to the filtered water outlet 6102;

and a driving mechanism 660 connected to the filtering mechanism 620 for driving the filtering mechanism 620 to rotate in the filtering chamber 610.

Filter mechanism 620 divides the interior of filter cavity 610 into an outer cavity and an inner cavity, wherein water inlet 6101 is communicated with the outer cavity, and filtered water outlet 6102 is communicated with the inner cavity. The water to be filtered enters the outer cavity from the water inlet 6101, passes through the filtering mechanism 620 and enters the content cavity to realize filtering, the filtering impurities carried in the water are attached to the outer wall of the filtering mechanism 620, and the water to be filtered and filtered the impurities can flow out from the filtered water outlet 6102 through the water outlet 621.

In detail, the filter mechanism 620 includes a filter net support, and a filter net covered on the filter net support. One end of the filter screen bracket extends into the filtered water outlet 6102 to form a water outlet joint 621, and the aperture size on the filter screen satisfies: the size of the filtering impurities such as thread scraps which can be removed by filtering is more than 17 μm + -2 μm in diameter and more than 500 μm + -50 μm in length.

When the filtering impurities in the filtering device 600 need to be cleaned, the driving mechanism 660 drives the filtering mechanism 620 to rotate, so that the water flow in the filtering cavity 610 can be stirred, and the filtering impurities attached to the outer wall of the filtering mechanism 620 are peeled off under the dual actions of centrifugal force and the stirring water flow and are dissolved into the water in the filtering cavity 610. The sewage mixed with the filtering impurities is discharged with the water flow through the sewage outlet 6103 on the filtering cavity 610, and the sewage is conveyed to the recycling device 500 through the sewage pipeline 240.

Cleaning particles 680 are also arranged between the inner wall of the filtering cavity 610 and the outer wall of the filtering mechanism 620 and used for cleaning the inner wall of the filtering cavity 610 and the outer wall of the filtering mechanism 620 along with the friction and collision of water flow. In the filtering process, the cleaning particles 680 continuously rub the inner wall of the filtering cavity 610 and the outer wall of the filtering mechanism 620 along with flowing water flow, so that the attached filtering impurities fall off, the deposition of the filtering impurities is prevented, and the filtering mechanism 620 is prevented from being covered by the filtering impurities too fast to influence the filtering efficiency. On the other hand, also avoided filtering adnexed filtration impurity thickness after accomplishing great, it is too firm to laminate at filtration cavity 610 inner wall or filtering mechanism 620 outer wall, when leading to clean filter equipment 600 in later stage, the problem that filtration impurity is difficult to detach.

When the driving mechanism 660 drives the filtering mechanism 620 to rotate in the filtering cavity 610 to realize self-cleaning, the cleaning particles 680 move in the filtering cavity 610 along with the action of the surging water flow and rub the inner wall of the filtering cavity 610 and the outer wall of the filtering mechanism 620, so that the stripping efficiency of the filtered impurities is improved, and the self-cleaning effect of the filtering device 600 is better.

A baffle 690 is further arranged in the filtering cavity 610, and a water through hole 691 is arranged on the baffle 690. The cleaning particles 680 are disposed on one side of the baffle 690 (i.e., the left side in fig. 2), and the filtered water outlet 6102 on the filtering chamber 610 is located on the other side of the baffle 690 (i.e., the right side in fig. 2) along with the drain outlet 6103.

Through the setting of baffle 690, can prevent to wash granule 680 to crossing the aggregation of water outlet 6102 at the filtering process, when filter equipment 600 carries out self-cleaning and discharges sewage, sewage carries and filters impurity and can pass baffle 690 through water hole 691 and be discharged by drain 6103, and wash granule 680 is blockked by baffle 690, can not be discharged along with the rivers by drain 6103, has avoided the loss of washing granule 680. Meanwhile, the cleaning particles 680 can be prevented from being accumulated in the sewage outlet 6103 to cause the blockage of the sewage outlet 6103 and influence the sewage discharge efficiency.

In this embodiment, a blowdown control valve 241 is disposed on the blowdown pipeline 240 and used for controlling on/off of the blowdown pipeline 240. When the filter device 600 filters the entering water, the drain control valve 241 is closed to cut off the drain line 240, so as to ensure that the water entering the filter device 600 can flow out through the filtered water outlet 6102 after filtering. When the sewage in the filtering apparatus 600 needs to be discharged, the sewage control valve 241 is opened to conduct the sewage line 240, and the sewage in the filtering apparatus 600 can be discharged into the recycling apparatus 500.

The flowmeter 243 is arranged between the water inlet end of the sewage draining pipeline 240 and the sewage draining control valve 241, and the flowmeter 243 detects the flow of the drained sewage only when the sewage draining control valve 241 is in an open state, so that whether the sewage draining process is blocked or not is judged.

Preferably, a return water control valve 231 is further provided outside the filtered water outlet 6102 of the filtering apparatus 600 for controlling whether the filtered water outlet 6102 can discharge water to the outside. When the filtering apparatus 600 filters the entering water, the backwater control valve 231 is in an open state, and when the filtering apparatus 600 is controlled to discharge the sewage, the backwater control valve 231 is closed, so that the filtering apparatus 600 cannot discharge the sewage from the filtered water outlet 6102, thereby ensuring that the sewage in the filtering apparatus 600 is sufficiently discharged from the sewage outlet 6103.

The specific structure of the filter module mounted on the washing device in this embodiment is further described with reference to fig. 1 and fig. 2, wherein the filter device 600 of the filter module is communicated with the water container 100 of the washing device, receives the water in the water container 100 for filtering, and the outputted water without the filtered impurities can be returned to the water container 100 along the water path structure inside the washing device, or discharged out of the washing device along the water drainage path structure.

Specifically, the washing device comprises a circulating filter pipeline, and the water inlet end and the water outlet end of the circulating filter pipeline are respectively communicated with the water containing barrel 100. The filtering device 600 is disposed on the circulation filtering pipeline, and the circulation filtering pipeline is further provided with a circulation pump 400. During the washing of the laundry by the washing apparatus, the circulation pump 400 is turned on to drive the water in the water drum 100 to flow into the filtering device 600 along the circulation filtering pipeline and return to the water drum 100 after filtering.

In detail, the bottom of the water container 100 is connected to a water container drain pipe 260, the water container drain pipe 260 is connected to an inlet end of the circulation pump 400, an outlet end of the circulation pump 400 is connected to the circulation pipeline 220, and the circulation pipeline 220 is further connected to a water inlet 6101 of the filter device 600. The filtered water outlet 6102 of the filtering device 600 is communicated with the water cartridge 100 through the return line 230. The water outlet end of the water return pipe 230 is specifically connected to the window pad 110 at the opening of the water containing cylinder 100, and water is returned to the water containing cylinder 100 through the window pad 110.

In a further aspect of this embodiment, a switching device 270 is disposed between the filtered water outlet 6102 of the filtering device 600 and the water return pipe 230, and a water inlet of the switching device 270 is communicated with 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 communicated with the water return pipeline 230, and the second water outlet is communicated with the external discharge pipeline 250 for discharging water to the outside of the washing device. The switching device 270 is provided with a switching mechanism therein for controlling the connection between the first water outlet and the water inlet and the connection between the second water outlet and the water inlet.

Through the setting of switching device 270, washing equipment both can realize the loop filter among the laundry process through same filter 600, can also realize two kinds of filtering capability of drainage filtration among the drainage process. Meanwhile, the circulating pump 400 and part of the pipeline structure are shared by the circulating filtration and the drainage filtration, so that the water path control structure in the washing equipment is simplified. By controlling the conducting direction of the switching device 270, the function switching between the circulation filtering and the drainage filtering can be realized, and the control logic is simple.

In this embodiment, in the process of the washing program being executed by the washing device, an additional program for guiding water to the filtering module for filtering is executed. Specifically, in the washing or rinsing stage, the switching device 270 connects the filtered water outlet 6102 of the filtering device 600 with the water return pipeline 230, and the circulating pump 400 is turned on for circulating filtration. In the draining stage, the switching device 270 connects the filtered water outlet 6102 of the filtering device 600 with the external drainage pipeline 250, and the circulating pump 400 is turned on for draining and filtering. After the filtering apparatus 600 continuously filters for a period of time, the sewage discharge operation of discharging the sewage to the recovering apparatus 500 is performed, thereby preventing excessive filtering impurities from being accumulated in the filtering apparatus 600.

In the working process of the filtering module, the flow meter 243 can detect the flow rate of the sewage discharged by the filtering device 600 in the sewage discharge pipeline 240, so as to determine whether the process of discharging the sewage from the filtering device 600 to the recovery device 500 is blocked, which is convenient for a user to determine the current state of the filtering module under the condition that the user cannot directly observe the blockage. Whether filter equipment 600 can normally carry out blowdown operation also can be confirmed to the washing equipment to in time make the response, avoid filter equipment 600 to continue to continuously operate under the unable circumstances of blowdown, can also remind the user in time to clear up recovery unit 500, avoid influencing the next operation of washing equipment.

Example two

As shown in fig. 1 and 3, the present embodiment is different from the first embodiment in that: the blockage detection means includes a water level detection means 580 for detecting water level information in the recovery means 500. The clogging detecting means judges whether or not the process of discharging the sewage from the filtering means 600 to the recovery means 500 is clogged based on the water level information in the recovery means 500.

Specifically, the recovery apparatus 500 of the present embodiment has a recovery chamber inside the housing 510, and the lint collecting assembly 570 is disposed inside the recovery chamber and encloses a collecting chamber that receives the contaminated water. The water outlet end of the sewage discharge pipeline 240 is communicated with the collection cavity, sewage carrying filtering impurities enters the collection cavity, flows into the recovery cavity outside the collection cavity after being filtered by the thread scrap collection assembly 570, and the filtering impurities are collected in the collection cavity.

A water level detecting means 580 is provided in the recovery chamber to detect water level information outside the collection chamber in the recovery chamber. Fig. 3 is a top view of the recycling device 500 of the present embodiment, and the water level detecting device 580 is specifically disposed inside the sidewall of the housing 510.

As a specific solution of this embodiment, the water level detecting device 580 detects a water level height in the recycling device 500, and if the water level height is greater than a preset water level, it is determined that the process of discharging the sewage from the filtering device 600 to the recycling device 500 is blocked.

The preset water level may be set to be close to the overflow water level of the recovery apparatus 500, that is, when it is detected that the height of the water level in the recovery apparatus 500 is greater than the preset water level, the recovery apparatus 500 is close to the full state. At this time, the filtering apparatus 600 continues to perform the sewage discharging operation, and the sewage is difficult to enter the recycling apparatus 500, which corresponds to the process of discharging the sewage being blocked. Even if the discharged sewage enters the recovery device 500, the recovery device 500 may overflow quickly.

Whether the water level height in the recovery device 500 reaches the preset water level or not is detected, and then whether the sewage discharge process of the filtering device 600 is blocked or not is judged, on one hand, the blockage problem can be timely fed back, and on the other hand, the recovery device 500 can be effectively prevented from overflowing.

As another specific solution of this embodiment, the water level detecting device 580 detects a water level change rate in the recycling device 500, and if the water level change rate is smaller than a preset change rate, it is determined that the process of discharging the sewage from the filtering device 600 to the recycling device 500 is blocked.

In the process that the filtering apparatus 600 normally discharges the sewage to the recovering apparatus 500, the sewage entering the collecting chamber of the lint collecting assembly 570 quickly flows to the outside of the collecting chamber through filtering, so that the height of the water level outside the collecting chamber gradually increases. However, once the lint collecting element 570 is clogged by the filtered impurities, the received sewage cannot be filtered and flows to the outside of the lint collecting element 570, so that the rising of the water level outside the collecting chamber is slowed down or even stopped, and the detected water level change rate is significantly decreased. If the filter device 600 or the sewage pipe 240 is clogged, the flow of sewage entering the recycling device 500 is significantly reduced, and the detected water level change rate is also reduced accordingly.

Whether the change rate of the water level in the recovery device 500 is smaller than the preset change rate or not is detected, whether the sewage discharge process of the filtering device 600 is blocked or not is judged, and the response to the blocking condition is timely and effective.

A specific structure of the water level detecting device 580 in this embodiment is shown in fig. 4, and includes several sets of water level probes 581 disposed at different height positions inside the recycling device, and the water level probes 581 contact with water to generate a feedback signal. The water level detecting device 580 further includes a step structure 582 having a plurality of step surfaces with different heights, and a set of water level probes 581 is disposed on each step surface.

Further, each group of water level probes 581 respectively comprises two electrodes arranged at intervals, and the two electrodes generate a feedback signal when being conducted by water.

When the water level detection device 580 detects the water level, as the height of the water level in the recovery device 500 rises, when the water level in the corresponding step structure 582 exceeds one step surface, the lower ends of the two electrodes are in contact with water at every time in the group of water level probes 581 on the corresponding step surface, so that the two electrode plates are conducted to generate a feedback signal. The current water level height in the recovery device 500 can be judged according to the respective on-off states of the plurality of sets of water level probes 581. The preset water level may be set to a step height corresponding to one of the group of water level probes 581, and when a signal indicating that the electrodes of the group of water level probes 581 are turned on is received, it is determined that the water level height is greater than the preset water level.

By adopting the water level detection device 580 with the above structure, the water level in the recovery device 500 can be continuously raised, so that the conducting time of the two electrodes in each group of water level probes 581 is obtained in the process that the two electrodes in each group of water level probes 581 are conducted one by one, and the water level change rate is calculated according to the conducting time difference of the two electrodes in different water level probes 581.

Or, after the two electrodes of any one set of water level probes 581 are conducted and a set time elapses, the two electrodes of the adjacent set of water level probes 581 are not conducted, and then it is determined that the current water level change rate is smaller than the preset change rate. For example, when two electrodes of a set of water level probes 581 are turned on and then turned off after a predetermined time, the current water level change rate is determined to be smaller than the predetermined change rate.

Another specific structure of the water level detecting device 580 is shown in fig. 5, which is an electrode type water level detecting device 583, and includes two electrode plates extending in a vertical direction for a certain length, and the two electrode plates are oppositely disposed at a certain interval. The capacitance value between the two electrode plates is changed along with the area of the electrode plates immersed below the water surface.

With the change of the water level in the recovery device 500, the area of the two electrode plates immersed below the liquid level changes, that is, the area of the opposite surfaces of the two electrode plates covered by the liquid changes. The two electrode plates form a capacitor, and the change is equivalent to the change of the dielectric medium between the two electrodes from air to water, so that the capacitance value between the two electrode plates is changed. The height of the water level in the recovery device 500 can be calculated according to the detected capacitance.

By adopting the water level detection device 580 with the above structure, on one hand, the specific water level height in the recovery device 500 can be obtained in real time, and whether the current water level height reaches the preset water level or not is judged. On the other hand, the water level change rate can be calculated according to the detected real-time change of the water level height, and whether the water level change rate is lower than the preset change rate or not is further judged. Thus, the water level in the recovery device 500 is detected more accurately.

In this embodiment, the filtering module is provided with the water level detecting device 580 as a blockage detecting device, and whether the sewage disposal process of the filtering device 600 is blocked is judged by detecting the water level information in the recycling device 500, so that the structure is simple, and the feedback of the blockage problem is timely and effective.

EXAMPLE III

As shown in fig. 1 and fig. 6, the present embodiment is different from the second embodiment in that: the specific structure of the recycling apparatus 500 is different.

Specifically, in the present embodiment, the structure of the recycling device 500 is similar to that of the embodiment, and the lint collecting assembly 570 at a certain height inside the re-housing 510 is arranged to divide the inside of the recycling device 500 into the first chamber 531 and the second chamber 532 which are distributed up and down. The water outlet end of the sewage discharging pipeline 240 is communicated with the first chamber 531, sewage carrying filtered impurities enters the first chamber 531, the sewage enters the second chamber 532 after being filtered by the filter screen of the thread scrap collecting assembly 570, and the filtered impurities are collected in the first chamber 531, namely, on the upper side surface of the thread scrap collecting assembly 570. Recovery unit 500 can separate out filtering impurity from the sewage that it received through line bits collection component 570, and convenience of customers directly handles filtering impurity of collection, has avoided filtering impurity to mix in aqueous, can't carry out the condition of effective processing to it.

In a specific embodiment of this embodiment, the water level detecting device 580 determines whether the process of discharging the sewage from the filtering device 600 to the recycling device 500 is blocked by detecting whether the height of the water level in the recycling device 500 is greater than a preset water level.

Specifically, the preset water level in the present embodiment is higher than the installation height of the lint collection assembly 570. When it is detected that the water level in the recycling apparatus 500 reaches the preset water level, there is a possibility that the recycling apparatus 500 is nearly filled with sewage, which may cause the filtering apparatus 600 to continue to discharge sewage, and the sewage cannot enter the recycling apparatus 500 to be blocked. Another possibility is that the lint collecting assembly 570 is blocked due to the filtered impurities, and the sewage entering the first chamber 531 cannot be filtered and then enters the lower second chamber 532, and remains in the first chamber 531, so that the water level gradually reaches the predetermined water level.

Therefore, in the above solution of this embodiment, the same determination logic as that of the embodiment may be still used, that is, if it is detected that the water level in the recovery device 500 is higher than the preset water level, it is determined that the process of discharging the sewage from the filtering device 600 to the recovery device 500 is blocked.

In another embodiment of this embodiment, the water level detecting device 580 determines whether the process of discharging the sewage from the filtering device 600 to the recycling device 500 is blocked by detecting whether the water level change rate in the recycling device 500 is smaller than a preset change rate.

Specifically, the water level detection device 580 detects a rate of change of the water level in the second chamber 532. When the filtering device 600 or the sewage pipeline 240 is blocked by the filtered impurities, the flow of sewage entering the recycling device 500 is reduced, and then the flow of water entering the second chamber 532 after being filtered by the debris collecting assembly 570 is also reduced correspondingly, which is reflected by a reduction in the rate of change of the water level in the second chamber 532. When the lint collecting assembly 570 is clogged due to the filtered impurities, the rate of change of the water level in the second chamber 532 is decreased since the polluted water introduced into the first chamber 531 is not filtered and then introduced into the second chamber 532.

Therefore, in the above-mentioned solution of the present embodiment, the same determination logic as that of the embodiment may be adopted, that is, if it is detected that the change rate of the water level in the recovery device 500 is smaller than the preset change rate, it is determined that the process of discharging the sewage from the filtering device 600 to the recovery device 500 is blocked.

This embodiment and the above-mentioned second embodiment adopt recovery unit 500 of isostructure not, still can be through the mode of detecting water level information, realize the judgement whether the blowdown process of filter equipment 600 takes place to block up.

Example four

As shown in fig. 1, the present embodiment provides a control method for a washing apparatus having a filter module in the above embodiments, including:

the washing equipment runs a washing program and executes an additional program for guiding water to the filtering module for filtering;

judging whether the pollution discharging process of the filtering apparatus 600 is blocked;

if the pollution discharge process is blocked, the additional program is stopped to be executed, and the washing program keeps the running state.

In the above-mentioned scheme, when it is judged that the clogging of the filtering apparatus 600 occurs, only the execution of the additional process is stopped, and the washing process is continued until the end. Therefore, various problems possibly caused by continuous filtering are avoided, the washing process can be finished under the condition that a user does not operate, and the automation degree is higher. Especially, when the user does not wait at the washing apparatus, the operation of the washing process is not stopped because the filter device 600 cannot discharge the sewage, thereby preventing the user complaint caused by the failure of the washing process.

In a specific solution of this embodiment, the stopping of executing the additional program includes: in the subsequent washing process, the circulation pump 400 is not started for circulation filtration, and the circulation pump 400 is started for drainage filtration only in the drainage stage.

Since the filter device 600 is disposed on the drain line of the washing apparatus, the drain water flow inevitably passes through the filter device 600. In this embodiment, the clogging determination condition, such as the preset flow rate in the first embodiment, or the preset water level or the preset change rate in the second and third embodiments, is adjusted, so that the filtering function of the filtering apparatus 600 is not completely lost although the clogging occurs in the sewage draining process of the filtering apparatus 600 when the additional program is stopped.

At this time, the washing apparatus does not perform the circulation filtering any more, and only when the washing apparatus is operated to the drainage stage, the circulation pump 400 is turned on to perform the drainage filtering, and the drainage water flow may pass through the filtering apparatus 600 without being discharged.

In a further aspect of this embodiment, if it is determined that the blowdown process is not clogged, the washing process is continuously run and the running state of the additional process is maintained.

Specifically, the control method of the washing apparatus in this embodiment is shown in fig. 7, and includes the following steps:

s1, running a washing program;

s2, executing an additional program for guiding water to filter the filtering module;

s3, judging whether the pollution discharge process of the filtering device 600 is blocked or not;

s4, stopping executing the additional program if the pollution discharge process is blocked, otherwise, continuing to execute the additional program;

and S5, continuing the washing program.

In a further aspect of this embodiment, when it is determined that the sewage draining process of the filtering apparatus 600 is blocked, the washing device further sends a prompt to prompt the user to clean the recycling apparatus 500 after the current washing procedure is completed, or to maintain the filtering apparatus 600. So, avoided the user can't know filter equipment 600's blowdown process and taken place the problem of jam, when can guaranteeing that washing equipment moves the washing procedure once more, filter module can normally work, especially filter equipment 600 can discharge the filtering impurity of accumulation in the filtering process smoothly, guarantees the filter effect.

In this embodiment, when the washing device obtains the working state of the filtering module and determines that the pollution discharge process of the filtering device 600 is blocked, the additional program may be stopped from being executed, and the washing program may be kept running, so that the washing device completes the washing process without user intervention, and the degree of automation is higher. Meanwhile, the problem that a large amount of washing time is wasted if a user cannot operate the washing machine in time because the washing program is suspended once the filtering module breaks down is solved.

EXAMPLE five

As shown in fig. 1, the present embodiment provides a washing apparatus having the filter module in the above embodiment.

Specifically, the recycling device 500 and the detergent feeding device in this embodiment are integrated, and may be disposed inside a water tank of the detergent feeding device. The recovery device 500 filters the received sewage, and the filtered water enters the inside of the water tank. The water tank is communicated with a water containing cylinder 100 of the washing equipment, and filtered water can be introduced into the water containing cylinder 100.

The inside distributor box that sets up the insertible/take out of basin, the last detergent that forms mutual isolation of distributor box adds the chamber and retrieves the installation cavity, and the detergent adds the chamber and retrieves the installation cavity and communicates the basin independently respectively. A recovery device 500 is installed in the recovery installation cavity.

The user can draw out the dispenser box, add the detergent into the detergent adding cavity, and then reinsert the dispenser box into the sink, and the washing equipment can automatically put the detergent in the detergent adding cavity into the water containing barrel 100 when the washing program is operated. When the recycling apparatus 500 needs to be cleaned, the dispenser box is drawn out, so that the thread scrap collecting assembly 570 in the recycling apparatus 500 is taken down for cleaning.

In this embodiment, the filtering capability of the filtering module is defined as the remaining usable number of the filtering module. When the residual usable times are reduced to preset times, the washing equipment sends out an alarm signal.

In this embodiment, according to the capability of the recycling apparatus 500 to collect the filtered impurities, the maximum number of times that the washing machine can run the washing program from the initial state (i.e. the state without collecting the filtered impurities) to the completely blocked state of the recycling apparatus 500 can be estimated.

Each time the washing apparatus runs a washing program, the number of times of use of the recycling apparatus 500 is increased in this embodiment. The washing device presets the total usable times S of the recovery device 500 from the initial state, wherein the total usable times S is not higher than the maximum number of times that the washing device can run the washing program, namely, the recovery device 500 cannot be completely blocked by the filtered impurities before the used times S1 of the recovery device reaches the total usable times S.

The remaining usable number of the filter module in this embodiment specifically refers to the remaining usable number of the recycling apparatus 500, that is, the difference between the total usable number S and the used number S1.

Generally, each time a user performs a drawing operation of the dispenser box, the user is instructed to add detergent to the dispenser box, and the washing apparatus performs a washing process. Therefore, in a further aspect of the present embodiment, the washing apparatus accumulates the number of times the dispenser box is drawn as the used number S1 of the recycling device 500, and calculates the remaining usable number S2= S-S1 of the recycling device 500, which is the remaining usable number of the filter module. When the calculated frequency S2 is reduced to the preset frequency S0, the washing equipment sends out an alarm signal to prompt a user to clean the recovery device 500.

Through above scheme, washing equipment can remind the user in time to clear up recovery unit 500 automatically, avoids washing equipment to run the washing procedure under recovery unit 500 takes place to block up, leads to the unable discharge of sewage among the filter equipment 600, influences the filter effect of laundry in-process.

In detail, in this embodiment, the value of the preset number of times S0 is set to 0, and when the accumulated number of times S1 of the washing device reaches S after the user draws out the dispenser box for a certain time, that is, S2 drops to 0, the washing device sends an alarm signal. The user can clean the recycling device 500 and then reinsert the dispenser cartridge into the sink of the detergent dispensing device.

Further, in the present embodiment, after the washing apparatus detects that the dispenser box is reinserted, the currently accumulated number S1 is cleared, and when the dispenser box is detected to be drawn again, the accumulated number S1 is recorded as 1.

For example, the total number of times S2 the washing apparatus is preset to be usable is 20, and the number of times S2 the washing apparatus counts is reduced every time the user pulls the dispenser box. When the user withdraws the dispenser box 20 times, the washing apparatus calculates S2=0, and issues an alarm signal. The user clears the recovery device 500 and then inserts the dispenser box again, and the current accumulated number of times S1 is cleared. When the washing equipment detects that the dispenser box is drawn out again, the currently accumulated number of times S1 is recorded as 1. Of course, the preset value S of the total usable times may be other values, such as any value in the range of 10 to 30.

It should be noted that, in the embodiment, after the alarm signal is sent by the washing apparatus, when it is detected that the dispenser box is reinserted, the operation of clearing the currently accumulated number S1 is directly performed, and it is not detected whether the recovery device 500 is cleaned. That is, after the washing apparatus issues the alarm signal by default, the dispenser box is reinserted into the sink after the user cleans the recycling device 500.

However, since the washing apparatus in this embodiment does not count up the number of times the washing process is actually performed but counts up the number of times the dispenser box is drawn, there may be a case where the user draws the dispenser box a plurality of times but only performs one washing process. Or, if the amount of the thread and scraps dropped from the laundry washed by the user is small, there may be a case where the user accumulatively pulls the dispenser box S1 to S, that is, the washing process is accumulatively operated S times, but the recycling device 500 still has a certain capacity, and may continue to receive the sewage and collect the filtered impurities in the sewage.

In the above two cases, when the washing device sends out the alarm signal, the user can choose not to clean the recovery device 500, but to directly insert the dispenser box into the water tank of the detergent putting device again, and continue to run the next washing program. However, at this time, the washing apparatus clears the currently accumulated number of times S1, and only when the number of times the dispenser box is drawn is accumulated to S0 again, the alarm is triggered again.

However, since a certain amount of filtered impurities are collected in the recycling device 500, the recycling device 500 may be blocked by the filtered impurities and cannot further receive the sewage discharged from the filtering device 600 before the washing apparatus runs the washing program again for a total number of times S0. But at this time, the washing equipment does not give an alarm because the accumulated number of times S1 does not reach S0.

In order to avoid the above problem, in a further embodiment of the present invention, the washing device may receive an instruction for adjusting the total usable times from the user, and adjust the value of the total usable times from the preset S to S'.

Specifically, after the washing apparatus sends the alarm signal, if the user determines that the present recovery device 500 does not need to be cleaned, the dispenser box may be directly inserted into the water tank of the detergent dispensing device after the detergent dispensing operation is completed. Then, a user can manually operate the washing device to automatically set the value of the total usable times according to the current collection amount of the filtered impurities in the recovery device 500, and if the preset value of the total usable times is S =20, the user manually adjusts the value to S' =5. In this way, the washing apparatus accumulates the number of times the dispenser box is drawn again, and when the dispenser box is drawn 5 times, that is, an alarm condition of S2= S' -S1=0 is triggered, the washing apparatus sends out an alarm signal.

In the above scheme, the washing device provides an editable function of the value of the total usable times of the recovery device 500, and if the user does not clean the recovery device 500 after the washing device gives an alarm, the value of the total usable times can be manually adjusted, so that the times of running the washing program accumulated before the washing device gives an alarm are reduced, and the recovery device 500 is ensured not to have a blockage fault in the process of running the washing program.

In a further scheme of this embodiment, after the washing device receives an adjustment instruction of a user to adjust a value of the total usable times, if the number of times that the dispenser box is pulled reaches S' after adjustment, that is, an alarm condition of S2=0 is triggered, the washing device sends an alarm signal, and then the value of the total usable times is automatically restored to a preset value S, for example, 20 times in this embodiment.

The operation that the user independently set up the value of usable total number of times generally takes place in the washing equipment and reports to the police but the user does not clear up recovery unit 500 under the condition, after the washing equipment sends alarm signal again, because the user did not clear up the operation during the warning of the previous time, recovery unit 500 probably reaches, or is comparatively close to at least by the state of filtering impurity jam. Therefore, the user is likely to manually clean the recovery device 500 during the alarm.

When the cleaned recycling device 500 is used again, the total number of times of running the washing program is accumulated again because the filtered impurities are not collected therein, that is, before the accumulated number of times of use of the recycling device 500 reaches the preset total number of times S of use again, the recycling device 500 is not substantially blocked. In this embodiment, the value of the total number of times that can be used by the automatic control is restored to the preset value S, so that the trouble of manual setting by a user is avoided, and the problem that the washing device alarms when the recovery device 500 can be used for a plurality of times can be avoided.

In a preferred embodiment of this embodiment, after the washing device detects that the dispenser box is drawn out and sends an alarm signal according to the adjusted total usable number value S', before receiving an instruction to start the washing program, if an adjustment instruction for the total usable number is not received, the value of the total usable number is restored to the preset value S, otherwise, the value of the total usable number is determined according to the received adjustment instruction.

After the washing equipment gives an alarm according to the adjusted value S 'of the total usable times, special conditions that the value S' set by the user in the previous time is not appropriate and the like may exist, so that the current recovery device 500 can still be continuously used under the condition that the cleaning is not performed. In the above scheme, when the above situation occurs, the user may continue to manually set the value of the total available times. And if the user does not manually set the value of the total usable times, the washing program is started, which indicates that the user has cleaned the recovery device 500, and the washing equipment automatically controls the value of the total usable times to be restored to the preset value S.

In this embodiment, the washing apparatus presets the total number of times the recycling device 500 can be used, and accumulates the number of times the recycling device 500 is pulled out along with the dispenser box of the detergent dispenser as the number of times the recycling device 500 has been used. When the used times reach the preset used times, the washing equipment sends an alarm signal to remind a user to clean the recovery device 500, and when the washing equipment runs a washing program, the recovery device 500 has enough capacity to receive the sewage discharged by the filtering device 600 and collect the filtering impurities in the sewage.

EXAMPLE six

As shown in fig. 1 to 3 and fig. 6, the present embodiment is further defined by any one of the above embodiments, in which the washing device executes an additional program for guiding water to the filtering module for filtering in the washing program, wherein the additional program is executed once every time the washing program is executed.

In this embodiment, the filtering capability of the filtering module includes: the filter module may also continue to execute additional programs for the number of times until the filter apparatus 600 and/or the recycling apparatus 500 is clogged in the current state.

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 filtering module is at least 20 times, that is, the filtering module can completely perform an additional process without clogging failure in at least 20 washing processes continuously operated in a case where there is no filtered foreign matter attached in the filtering apparatus 600 and the filtered foreign matter and the contaminated water are not collected in the recovery apparatus 500.

In the above description of the present embodiment, the "complete execution of the additional program" means that the circulation filtering is performed for a set time period in the washing stage and the rinsing stage, and the drain filtering is performed in the drain stage.

After the filter module completely executes the additional program in the washing program each time, the washing device records that the current filtering capacity of the filter module is subtracted from the original filtering capacity once. If the time length of the circulating filtration of the filtering module is shorter than the set time length in the washing program, the loss amount of the filtering capacity in the washing program can be determined according to the ratio of the actual time length of the circulating filtration to the set time length, and then the current filtering capacity of the filtering module is calculated.

In a preferred embodiment of this embodiment, a value of the filtering threshold is set to 1 or 2. When the current filtering capacity of the filtering module is lower than the filtering threshold value, the water is controlled to stop being guided to the filtering module, and the circular filtering is not carried out in the subsequent process of the washing program.

In the scheme, when the filtering capacity of the filtering module is close to 0 but does not reach 0, the washing equipment controls to stop water guiding to the filtering module, so that the problem that water guiding to the filtering module cannot be controlled to stop in time before the filtering module is blocked and other faults caused by deviation between the filtering capacity calculation and the current actual state of the filtering module is solved.

In another preferred scheme of this embodiment, the initial filtering capability of the filtering module is denoted as X, and a value of the filtering threshold is set to X/5 to X/3. For example, if the initial filtering capacity of the filtering module is 20 times, the value of the filtering threshold may be set to 4 to 6 times. When the current filtering capacity of the filtering module is lower than the filtering threshold value, the control reduces the frequency and/or the duration of water guiding to the filtering module.

In the above scheme, the value of the filtering threshold is relatively high, and even if the calculation of the filtering capacity by the washing equipment is deviated from the current actual state of the filtering module, the situation that the filtering module is blocked or has other faults affecting the filtering effect when the calculated filtering capacity is lower than the filtering threshold can not occur basically. At the moment, the washing program is continuously operated in a mode of reducing the frequency and/or the duration of water guide to the filtering module, so that a part of filtering effect can be kept, and the washing effect of the clothes is improved.

The specific manner for reducing the frequency and/or duration of water introduction to the filtering module is described in detail in the above embodiments, and is not described in detail in this embodiment.

In a further aspect of this embodiment, the filtering device 600 filters the washing water and the drain water of the washing equipment to filter out filtering impurities with a size greater than 50 μm, wherein the filtering impurities may include micro plastic. In particular, the filtering foreign matter may include plastic fiber having a length of more than 50 μm and a diameter of 10 to 1000 μm. Preferably, the plastic fibers have a length of 400 to 600 μm, the most common length in the distribution being 500 μm ± 50 μm. Furthermore, 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 the micro-plastic with the size, a filter screen in the filter device 600 is selected to be 20-500 meshes. In order to ensure that the recycling device 500 can collect the micro plastics carried in the sewage as sufficiently as possible, and the micro plastics filtered by the filtering device 600 can pass through the thread scrap collecting assembly 570 in the recycling device 500, the size of the aperture on the filter screen in the thread scrap collecting assembly 570 is at least not larger than the aperture of the filter screen in the filtering device 600, that is, the mesh number of the filter screen in the thread scrap collecting assembly 570 is not smaller than the mesh number of the filter screen in the filtering device 600 by 20-500 meshes.

In this embodiment, a large number of test tests are performed on different kinds of clothes and different washing procedures in advance, and it is found that the mesh number of the filter net in the thread scrap collecting assembly 570 and the mesh number of the filter net in the filter device 600 are set within the above range, so that plastic fibers with the above size can be filtered from the washing water and the drainage water of the washing equipment, and finally, micro plastic particles accounting for more than 80% of the total content of the water can be collected in the recovery device 500, so that the content of the micro plastic in the drainage water flow of the final washing equipment is greatly reduced, and the standard of direct drainage can be met.

In this embodiment, since the filtering apparatus 600 has a self-cleaning function, the filtering capacity loss of the filtering module is mainly reflected in the recycling apparatus 500. For example, in the recycling apparatus 500, as the total amount of the collected filtering impurities increases, the thread scrap collecting assembly 570 is gradually covered by the filtering impurities, and the filtering impurities block the meshes of the filter screen, so that the thread scrap collecting assembly 570 cannot perform the filtering function on the sewage.

In this embodiment, a large number of test tests are performed on different types of clothes and different washing programs in advance, and the structure of the lint collecting assembly 570 is adjusted to change the maximum amount of filtering impurities that can be collected, so that the filtering module can completely execute an additional program in 10-30 washing programs that continuously run at least on the premise that a user does not clean the recycling device 500, thereby ensuring the user experience.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical spirit of the present invention still fall within the scope of the present invention.
