Description

A filter module and washing equipment

technical field

The utility model belongs to the technical field of washing equipment, in particular to a filter module and washing equipment.

Background technique

The washing equipment used to wash clothes, such as a washing machine, in the process of washing the clothes, due to the friction between the clothes and the clothes and the washing machine itself, will cause the clothes to produce lint falling off and mixed 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 washing, affecting the washing effect of the clothes. For this reason, a filter for filtering lint is installed on the existing washing machine, and the washing water is continuously passed through the filter during the washing process, so that the lint is removed from the washing water.

However, filter impurities such as filtered lint will continue to accumulate in the filter. If it is not cleaned for a long time, it may cause bacterial growth inside the filter and pollute the clothes. In order to save the user from the trouble of manually disassembling the filter for cleaning, a filter with a self-cleaning function is proposed in the prior art, which can automatically clean the filter impurities accumulated therein and discharge it with the water flow.

However, in recent years, the concept of microplastics has been proposed in the field of environmental protection and has gradually received increasing attention. The study found that an important source of microplastics is wastewater discharged from household washing machines. This is because with the popularization 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 enter the ecological cycle directly with the drainage water, and will eventually accumulate in the human body through the natural biological chain, which may affect human health. For this reason, relevant standards have been established for the content of microplastics in washing machine drainage in some regions. The above-mentioned filter with self-cleaning function will directly discharge the cleaned out filter impurities with the water flow, and the filter impurities often contain a large amount of microplastics, which will cause the content of microplastics in the washing machine drainage water to be too high, which cannot meet the requirements. The issue of emission standards.

Therefore, there is an urgent need for a solution that can process the filter impurities discharged from the filter device. For example, for the drainage after the filter device is self-cleaning, the filter impurities in the water flow are intercepted to prevent the filter impurities from entering the drainage water flow of the washing machine. However, the structure used to intercept and filter impurities often needs to be removed by the user for cleaning, and then reinstalled in the washing machine after cleaning. If the user does not install the structure in place, or forgets to install the structure, the filter impurities may not be successfully intercepted, and the microplastic content in the washing machine drainage water may exceed the standard.

In view of this, the utility model is proposed.

Embodiment one

As shown in FIG. 1 to FIG. 6 , this embodiment provides a filter module and a washing device having the filter module. When the filter module is applied to the washing device, it is used to realize the function of filtering water. The washing equipment may be a washing machine, an all-in-one washing and drying machine, a nursing machine, etc., which have the function of washing clothes.

Specifically, the washing device includes a water storage tank 100 , and the filter module communicates with the water storage tank 100 for filtering the water in the water storage tank 100 .

In this embodiment, the filter module specifically includes a filter device 600 and a sewage receiving device 500 . Wherein, the filter device 600 has a self-cleaning function, and a sewage outlet 6103 is arranged on it, and the sewage generated after self-cleaning can be discharged through the sewage outlet 6103, and the sewage carries the filter impurities accumulated in the filtering process. The sewage receiving device 500 is arranged downstream of the sewage outlet 6103 of the filtering device 600 and can receive sewage discharged from the filtering device 600 .

In the above solution, the filter device 600 of the filter module is used to receive the water in the water tank 100 of the washing equipment for filtering, and the filter device 600 has a certain self-cleaning ability, and can discharge the filter impurities accumulated in the filter process into the sewage receiving device 500 In the collection assembly 570, avoid a large amount of filter impurities from accumulating and affecting the filtration efficiency. Utilizing the sewage receiving device 500 to receive the sewage discharged from the filtering device 600, instead of converging the sewage into the drainage water flow of the washing equipment and discharging it directly, avoids the problem that the microplastic contained in the filtered impurities directly enters the ecological cycle with the washing equipment drainage.

Specifically, in this embodiment, a collection assembly 570 is provided inside the sewage receiving device 500 . The collection assembly 570 has a collection chamber 571 for collecting filtered impurities in the sewage. The collection chamber 571 communicates with the sewage outlet 6103 of the filter device 600 . The sewage discharged from the filter device 600 directly enters the collection cavity 571 , and the collection component 570 can filter the sewage, thereby collecting filter impurities such as lint in the sewage in the collection cavity 571 .

The collection assembly 570 of this embodiment is detachably installed inside the sewage receiving device 500 . When the filter impurities accumulated in the collection cavity 571 reach a certain amount, the user can remove the collection assembly 570 from the sewage receiving device 500 for cleaning, and then reinstall the cleaned collection assembly 570 back into the sewage receiving device 500, waiting for the follow-up use.

However, the collection assembly 570 is detachable inside the sewage receiving device 500 , and it is very likely that the collection assembly 570 is not properly installed, or even the user forgets to install the collection assembly 570 . At this time, if the washing equipment operates and uses the filter module to realize the filter function, it will cause the problem that the filter impurities cannot be collected in the collection chamber 571 .

In order to ensure that the collection assembly 570 can effectively collect filtered impurities, the filter module of this embodiment is also provided with a position detection device for detecting whether the collection assembly 570 is installed in place in the sewage receiving device 500 . Through the position detection device, the installation situation of the collection assembly 570 can be fed back, and then the washing equipment can remind the user in time when the collection assembly 570 is not installed in place, so as to avoid the operation of the washing equipment when the collection assembly 570 is not installed in place. In this way, it is prevented that the filter device 600 discharges the sewage when the collecting assembly 570 is not installed in place, resulting in the problem that the filtered impurities in the sewage cannot be effectively collected.

In a further solution of this embodiment, the sewage receiving device 500 includes an accommodating housing 510 , and the collecting assembly 570 is installed inside the accommodating housing 510 . The position detection device includes a detection element disposed on the housing 510 and a detected element disposed on the collection assembly 570 . When the detected element is within the effective detection range of the detection element, the detection element can be triggered, thereby realizing the detection of whether the collection assembly 570 is installed in place.

It can be understood that the setting positions of the detecting element and the detected element can be reversed, that is, the detecting element is arranged on the collection assembly, and the detected element is arranged on the containing housing, and the alignment can also be realized. Detection of whether the collection components are installed in place.

Further, in this embodiment, the detection element is a reed switch 820 disposed on the housing case 510 , and the detected element is a magnetic member 810 disposed on the collection assembly 570 . The position detection device also includes a detection circuit on which the reed switch 820 is arranged. When the collecting assembly 570 is installed in the sewage receiving device 500 , the magnetic part 810 is located within the effective detection range of the reed switch 820 , and then the reed switch 820 conducts the detection circuit under the action of the magnetic part 810 .

In detail, the reed switch 820 has a first electrode 821 and a second electrode 822 inside, and is connected in series to the detection circuit through a signal output wire 823 . The first electrode 821 and the second electrode 822 are not in contact under normal conditions, so that the detection circuit is in an off state. When the collection assembly 570 is installed in place, the magnetic member 810 is located close to the reed switch 820, and the reed switch 820 is subjected to the magnetic action of the magnetic member 810, so that the first electrode 821 and the second electrode 822 are in contact, thereby conducting the detection circuit. According to the on-off state of the detection circuit, the washing equipment can judge whether the collecting assembly 570 is installed in place.

FIG. 2 and FIG. 3 are top structural views of the sewage receiving device 500 in this embodiment, and FIG. 4 is a cross-sectional view of the sewage receiving device 500 in FIG. 3 along the dotted line.

As shown in FIG. 4 , in a preferred solution of this embodiment, the reed switch 820 is arranged on the outside of the housing 510 , and is arranged in close contact with the outer wall of the housing 510 . On the one hand, it facilitates the lead-out of the signal output wire 823 on the reed switch 820 , and on the other hand, it also reduces the risk of damage caused by contacting the reed switch 820 with the sewage discharged into the sewage receiving device 500 .

The collection assembly 570 includes a collection chamber wall 572 surrounding the collection chamber 571 , and the magnetic member 810 is embedded in the collection chamber wall 572 . The collection chamber wall 572 is embedded with a magnetic piece 810 that cooperates with the reed switch 820, which avoids the problem that the magnetic piece 810 may fall off when the collection assembly 570 is repeatedly disassembled, thereby ensuring effective detection of the installation of the collection assembly 570.

Further, the filter module of this embodiment also includes a sewage pipeline 240, one end of the sewage pipeline 240 (ie, its water inlet end) is connected to the sewage outlet 6103 of the filter device 600, and the other end (ie, its water outlet end) passes through the accommodating The sidewall of the housing 510 communicates with the collection cavity 571 of the collection assembly 570 .

The detection element reed switch 820 is disposed on the side wall of the housing 510 through which the sewage pipeline 240 passes, that is, the left side wall of the housing 510 in FIG. 4 . The magnetic part 810 of the detected element is located on the side where the collection assembly 570 communicates with the sewage pipeline 240 , that is, the magnetic part 810 is embedded in the left side wall of the collection chamber wall 572 in FIG. 4 .

In the above solution, since the collection assembly 570 is connected to the sewage pipeline 240 to receive sewage and collect filtered impurities, the reed switch 820 and the magnetic piece 810 are respectively arranged at positions close to the water outlet of the sewage pipeline 240, which can be more efficient. Accurately detect whether the current installation position of the collecting assembly 570 can realize an effective connection with the water outlet of the sewage pipeline 240 . In this way, when it is detected that the collection assembly 570 is installed in place in the sewage receiving device 500, it can be ensured that the water outlet end of the sewage pipeline 240 has been effectively connected to the collection assembly 570, thereby effectively collecting the filter impurities in the sewage and preventing the filter impurities from being filtered out. The microplastics are not intercepted and discharged with the washing equipment drainage.

In detail, as shown in FIG. 4 , when the collection assembly 570 is installed in place in the housing 510 , the magnetic member 810 is close to the reed switch 820 on the outside of the housing 510 , so that the first electrode 821 and the second electrode 821 of the reed switch 820 The two electrodes 822 are in contact with each other under the magnetic action of the magnetic member 810 , thereby conducting the detection circuit.

As shown in FIG. 5, when the collection assembly 570 is not properly installed in the housing 510, since there is a certain distance between the magnetic part 810 and the reed switch 820, the magnetic effect on the reed switch 820 is extremely weak. The first electrode 821 and the second electrode 822 are kept separated, so that the detection circuit is in an off state. Similarly, as shown in FIG. 6, when the collecting assembly 570 is not installed in the housing 510, the reed switch 820 is not subjected to the magnetic field at all, and the first electrode 821 and the second electrode 822 remain separated, so that the detection circuit is in an off state. open state.

In the detailed scheme of this embodiment, a number of water permeable holes are opened on the wall of the collection chamber 572, and the collection assembly 570 also includes a filter screen, which covers the water permeable holes, and is used to filter the received sewage, so that The filtered impurities are collected in the collection chamber 571 . The sewage discharged from the filter device 600 enters the collection chamber 571 along the sewage pipeline 240, and the filtered impurities are intercepted by the filter screen and collected in the collection chamber 571. housing 510.

In this embodiment, the containing case 510 is push-pullly arranged on the box body 10 of the washing machine, and the user pulls out the containing case 510 to remove the internal collection assembly 570 to clean the filtered impurities collected therein. Filtering the sewage through the collecting component 570 can separate the filtered impurities from the water, avoiding the problem that the filtered impurities are mixed in the water, which is difficult for the user to handle.

In a preferred solution of this embodiment, a water outlet (not shown in the figure) may be provided on the containing housing 510 for discharging filtered water. The water outlet can be communicated with the water storage cylinder 100 of the washing equipment, and the filtered water free of filtered impurities is passed into the water storage cylinder 100 for reuse. Alternatively, the water outlet can also lead to the outside of the washing equipment, and the filtered water free of filtered impurities is discharged out of the washing equipment.

By arranging a water outlet capable of self-drainage on the housing 510, the retention of sewage discharged from the filter device 600 in the housing 510 is avoided, and the internal volume of the housing 510 can be reduced without washing equipment The problem of water overflow in the sewage receiving device 500 during operation. At the same time, when the user pulls out the housing 510 for cleaning, he only needs to remove the collection assembly 570 to clean the filter impurities inside, without removing the housing 510 from the box body 10, so as to manually pour out the accumulated sewage ,More convenient.

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

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

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

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

The filtering mechanism 620 divides the inside of the filtering cavity 610 into an outer cavity and an inner cavity, wherein the water inlet 6101 communicates with the outer cavity, and the filtered water outlet 6102 communicates with the inner cavity. The water to be filtered enters the outer cavity through the water inlet 6101, passes through the filter mechanism 620 and enters the inner cavity to achieve filtration, and the filtered impurities carried in the water adhere to the outer wall of the filter mechanism 620, and the water that removes the filtered impurities can pass through the water outlet connector 621 Outflow from filtered water outlet 6102.

In detail, the filter mechanism 620 includes a filter screen support, and a filter screen covering the filter screen support. One end of the filter screen 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 drive 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 under the double action of centrifugal force and turbulent water flow. Peel off and melt into the water in the filter cavity 610. The sewage mixed with filtered impurities is discharged from the sewage outlet 6103 on the filter cavity 610 along with the water flow, and the sewage is transported to the sewage receiving device 500 through the sewage pipeline 240 .

Further preferably, cleaning particles 680 are provided between the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620 for cleaning the inner wall of the filter cavity 610 and the outer wall of the filter mechanism 620 with friction and collision with 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, so that the attached filter impurities fall off, thereby preventing the deposition of filter impurities and preventing the filter mechanism 620 from being covered by filter impurities too quickly. affect the filtration efficiency. On the other hand, it also avoids the problem that the filter impurities attached after the filtration are thicker, and the inner wall of the filter chamber 610 or the outer wall of the filter mechanism 620 is too firm, resulting in the problem that the filter impurities are difficult to remove when the filter device 600 is cleaned later.

And when the driving mechanism 660 drives the filter mechanism 620 to rotate in the filter cavity 610 to realize self-cleaning, the cleaning particles 680 move in the filter cavity 610 with 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 , so as to improve the stripping efficiency of filtering impurities, and the self-cleaning effect of the filtering 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 plate 690 (ie, the left side in FIG. side).

Through the setting of the baffle 690, the cleaning particles 680 can be prevented from accumulating towards the filtered water outlet 6102 during the filtration process. When the filter device 600 performs self-cleaning and discharges the sewage, the sewage carrying the filtered impurities can pass through the water hole 691 and pass through the baffle 690. The sewage outlet 6103 is discharged, while the cleaning particles 680 are blocked by the baffle 690 and will not be discharged with the water flow through 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 at the sewage outlet 6103, causing blockage of the sewage outlet 6103 and affecting the sewage discharge efficiency.

In a further solution of this embodiment, a blowdown control valve 241 is provided on the blowdown pipeline 240 for controlling the on-off of the blowdown pipeline 240 . When the filter device 600 is filtering the received water, the blowdown control valve 241 is in a closed state, and the blowdown pipeline 240 is cut off. Ensure that the water entering the filtering 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 sewage receiving device 500 .

Preferably, the filtered water outlet 6102 of the filtering device 600 is connected to the return water pipeline 230 for delivering the filtered water of the filtering device 600 . A return water control valve 231 is provided on the return water pipeline 230 for on-off of the return water pipeline 230 . When the filter device 600 is filtering, the return water control valve 231 is in an open state, and when the filter device 600 is controlled to discharge sewage, the return water control valve 231 is closed so that the filter device 600 cannot discharge water from the filtered water outlet 6102, thereby ensuring that the filter device The sewage in 600 is fully discharged by sewage outlet 6103.

In this embodiment, the filtering device 600 can filter out the filtering impurities with a size greater than 50 μm, and the filtering impurities can include microplastics. In particular, plastic fibers with a length greater than 50 μm and a diameter of 10-1000 μm may be included in the filtered impurities. Preferably, said plastic fibers have a length of 400-600 μm, the most common length in the distribution being 500 μm±50 μm. These plastic fibers preferably have a diameter of 10-50 μm, most commonly having a diameter of 17 μm±2 μm.

The filter device 600 cleans the filtered impurities, and discharges the sewage carrying the above-mentioned filtered impurities into the sewage receiving device 500 , and the final collection purpose of the filtered impurities is realized through the collection component 570 inside the sewage receiving device 500 . In order to ensure that the above-sized microplastics or plastic fibers carried in the sewage can be fully collected by the collection assembly 570, when the collection assembly 570 filters the sewage, the size of the filtered impurities that can be filtered and collected should at least not be smaller than that of the filter device 600. The size of the filtered impurities. For example, the filter device 600 can filter out the filter impurities with a size larger than 50 μm, so when the collection component 570 filters the received sewage, it must at least ensure that the filter impurities with a size larger than 50 μm cannot pass through, and preferably the filter impurities with a size slightly smaller than 50 μm cannot pass through. , can ensure that the microplastics in the sewage are collected in the collection cavity 571 of the collection assembly 570 as much as possible.

In order to filter and remove microplastics of the above size, the filter mesh of the filter mechanism 620 in the filter device 600 is selected from 20 mesh to 500 mesh. In order to ensure that the collection assembly 570 inside the sewage receiving device 500 can collect the microplastics carried in the sewage as fully as possible, and avoid the microplastics filtered out by the filtering device 600 from passing through the collection assembly 570 in the sewage receiving device 500 In the case of the filter screen, the size of the aperture on the filter screen of the collection assembly 570 is at least not greater than the aperture of the filter screen in the filter device 600, that is, the mesh number of the filter screen in the collection assembly 570 is not less than the mesh number 20 of the filter screen in the filter device 600 Mesh to 500 mesh.

Receive the start command of the washing program;

If it is judged that the collection assembly 570 has been installed in place, the washing program will start to run.

Further, if it is judged that the collecting assembly 570 is not installed in place, the washing equipment will be locked and an alarm signal will be sent.

It should be noted that the "collection assembly 570 is not installed in place" described in this embodiment includes at least the following two situations, that is, the collection assembly 570 has been installed inside the housing 510 but is not installed in place (as shown in Figure 5 ), and the collection assembly 570 is not installed inside the containing housing 510 (as shown in FIG. 6 ).

In this embodiment, the washing device does not start running directly after receiving the start instruction of the washing program, but first judges the installation condition of the collecting assembly 570 . Only when the collection assembly 570 has been installed in place, can the washing process be started to ensure that the sewage discharged from the filter device 600 during the washing process can accurately flow into the collection assembly 570 of the sewage receiving device 500, and the sewage can be discharged through the collection assembly 570. Collection of filtered impurities.

And if it is judged that the installation of the collection assembly 570 is not in place, or even when the collection assembly 570 is not installed, the washing equipment can be automatically locked and the washing program will not run, thus avoiding the problem of being unable to effectively collect and filter impurities. The washing equipment can also send an alarm signal when it is judged that the collection assembly 570 is not installed in place, thereby reminding the user to manually check the installation cavity of the collection assembly 570 in time to ensure that the washing equipment can start running as soon as possible.

The alarm signal described in this embodiment may be in various forms such as flashing of an alarm light, buzzer sound, or voice reminder, which is not specifically limited here.

In the specific solution of this embodiment, the filter module feeds back the installation condition of the collection assembly 570 to the washing equipment through the cooperation of the magnetic member 810 and the reed switch 820 . The reed switch 820 is connected to the detection circuit, and the washing device can judge whether the collection assembly 570 is installed properly by obtaining the on-off state of the detection circuit.

Specifically, the washing device acquires the on-off state of the detection circuit after receiving the start instruction of the washing program. If the detection circuit is in the on state, it is judged that the collection assembly 570 has been installed in place; if the detection circuit is in the off state, it is judged that the collection assembly 570 is not installed in place.

Further, the washing device in this embodiment is provided with a program start key, and the washing device receiving a washing program start instruction specifically refers to: the washing device receives a signal that the program start key is triggered.

In detail, as shown in FIG. 7, the method for controlling washing equipment described in this embodiment includes the following steps:

S1. Receive the signal that the program start key is triggered;

S2. Obtain the on-off state of the detection circuit, and determine whether the detection circuit is in a conduction state;

S3. If the detection circuit is in the conduction state, it is judged that the collection component has been installed in place, and the washing equipment starts to run the washing program, otherwise, it is judged that the collection component is not installed in place, and step S4 is executed;

S4. Lock the washing equipment and send out an alarm message.

In a further solution of this embodiment, after the washing device judges that the collection assembly 570 is not installed in place, if it detects that the housing case 510 is pulled out and pushed into the box body 10 again, then the on-off state of the detection circuit is obtained again, and the collection The installation status of component 570 is judged.

Specifically, as shown in Figure 8, after the above step S4, the following steps are also included:

S5. Detect that the containing housing is pulled out of the box, and stop sending out the alarm prompt message;

S6. Detect that the containing housing is pushed into the cabinet, unlock the washing device, and return to step S2.
