The following describes the filter element cleaning method, filter element cleaning device and water purification equipment of the water purification equipment proposed by the utility model with reference to the accompanying drawings.

It should be noted that the filter element cleaning method proposed by the utility model needs to realize the cleaning of the filter element 1 on a certain structural basis. Specifically, the structure required by the filter element cleaning method is the water purification equipment and its components described above. The filter element assembly, wherein the system can control the operating parameters of the circuit such as AC frequency, voltage, current, and energization time, so that the electric field and magnetic field generated by the first electrode 21 and the second electrode 22 can be switched between low-voltage electric field and high-frequency magnetic field quality inspection, In this way, different pollutants are cleaned in a targeted manner.

As shown in Fig. 5, according to the filter element cleaning method of the water purification equipment embodiment of the first aspect of the present invention, wherein, the filter element 1 of the water purification equipment is provided with a first electrode 21 and a second electrode 22 to be suitable for the filter element 1 An electric field and a magnetic field are formed inside, and the filter element cleaning methods include:

Step 100, according to the filtered water information filtered by the filter element 1, the pollutant information in the filtered water is obtained, and the pollutant information includes the pollutant type;

Step 200, control the first electrode 21 and the second electrode 22 to switch between a low-voltage electric field and a high-frequency magnetic field according to the type of pollutant.

According to the filter element cleaning method of the embodiment of the present invention, by judging the types of pollutants contained in the filtered water filtered by the filter element 1, the first electrode 21 and the second electrode 22 are controlled in a targeted manner to form a low-voltage electric field or a high-frequency electric field in the filter element 1. The magnetic field enables targeted cleaning of different contaminant species. For example, the system performs low-voltage electric field sterilization treatment for microorganisms, or high-frequency magnetic field scale suppression treatment for scale, so that not only the decontamination effect and decontamination efficiency can be improved, thereby further ensuring the normal operation of the filter element 1 and prolonging the service life of the filter element 1. service life, the filtered water can also be sterilized by the electric field and magnetic field, which further improves the purification effect of the filter element 1 and ensures the safety of water for users.

According to some embodiments of the present utility model, in the step of controlling the first electrode 21 and the second electrode 2 to switch between the low-voltage electric field and the high-frequency magnetic field according to the type of pollutants, it specifically includes:

Determining that the type of pollutant is a microorganism, controlling the first electrode 21 and the second electrode 22 to form a low-voltage electric field in the filter element 1 for sterilization;

It is determined that the type of pollutant is scale, and the first electrode 21 and the second electrode 22 are controlled to form a high-frequency magnetic field in the filter element 1 to suppress the generation of scale.

In this embodiment, the filter element cleaning method mainly uses low-voltage electric field sterilization technology and high-frequency magnetic field scale suppression technology in the specific working process.

It can be understood that the low-voltage electric field can be used to purify the water quality of microorganisms (such as bacteria and algae). Among them, changing the normal electric field strength of biological survival can change or affect the physiological metabolism of bacteria (such as gene expression programs or enzyme activities, etc.), so that the survival of bacteria is abnormal, and the above process leads to one of the reasons for the death of bacteria. Moreover, the external electric field destroys the ion channels on the cell membrane and changes the internal control current that regulates cell functions, thereby affecting the life of bacteria. In addition, the bacteria-containing liquid passes through a strong electric field to cause a changing current to pass through the liquid, and the cells on the conductive path are killed by the impact of high-speed moving electrons, thereby achieving the purpose of sterilization.

Furthermore, the existence of the electric field will also affect the formation of scale in water, so as to achieve the purpose of scale inhibition. Among them, the high-frequency magnetic field has the advantage of better anti-scaling and descaling effects, and the formation of the magnetic field can be realized by electrifying the electrodes. Therefore, applying different circuits to the first electrode 21 and the second electrode 22 can realize the low-voltage electric field or high-voltage electric field in the filter element 1. The switching of the high-frequency magnetic field can achieve the purpose of sterilization or scale inhibition in a targeted manner.

According to the filter element cleaning method of the embodiment of the present invention, the first electrode 21 and the second electrode 22 can be in a normally open state during the working process of the filter element 1, that is, during the working process of the filter element 1, the first electrode 21 and the second electrode 22 The two electrodes 22 are always in the energized state. At this time, the user can control the formation of the low-voltage electric field or the high-frequency magnetic field by controlling the working parameters of the circuit.

Alternatively, the first electrode 21 and the second electrode 22 are intermittently turned on during the working process of the filter element 1, that is, during the working process of the filter element 1, when the pollutants in the filter element 1 reach a certain set condition, The system energizes the first electrode 21 and the second electrode 22 to form a low-voltage electric field or a high-frequency magnetic field. Wherein, the above-mentioned "certain set condition" can be conditions such as that the pollutant content reaches the set content standard, the pollutant type is the set type, or a combination of the above two conditions, and the present invention does not make special limitations here.

In the following, the first electrode 21 and the second electrode 22 are intermittently turned on during the working process of the filter element 1 as an example for illustration: after determining the specific types of pollutants contained in the filtered water of the filter element 1, the first The electrodes 21 and the second electrodes 22 are energized, and by adjusting the working parameters of the first electrodes 21 and the second electrodes 22, the first electrodes 21 and the second electrodes 22 are switched between low voltage electric field and high frequency magnetic field. Wherein, the working parameters of the first electrode 21 and the second electrode 22 include parameters such as voltage, current, alternating current frequency, and electrification duration.

It should be noted that when the type of pollutant is determined to be microorganisms, since the system needs to use a low-voltage electric field for sterilization at this time, in order to ensure the generation of a low-voltage electric field in the filter element 1, the main operating parameters adjusted by the system are the first electrode 21 and the first electrode 21. The voltage value of the second electrode 22 is large. At this time, this method does not limit the type of electricity that is passed into the first electrode 21 and the second electrode 22, that is, the first electrode 21 and the second electrode 22 can be passed into alternating current or Direct current, as long as the system controls the voltage values of the first electrode 21 and the second electrode 22 within the set voltage range.

When it is determined that the type of pollutant is scale, the system needs to use a high-frequency magnetic field to suppress the generation of scale. Therefore, in order to ensure the generation of a high-frequency magnetic field in the filter element 1, the main operating parameters adjusted by the system are the first electrode 21 and The frequency of the alternating current supplied to the second electrode 22 means that the first electrode 21 and the second electrode 22 need to be supplied with an alternating current of a specific frequency, so as to generate a high frequency magnetic field in the filter element 1 .

It should also be noted that, in actual application, the pollutants contained in the filtered water are often not a single component, but complex pollutants composed of many different types of pollutants. For example, the filtered water contains In the case of microorganisms and scale, since the system needs to use low-voltage electric field and high-frequency magnetic field to achieve the purpose of sterilization and scale inhibition respectively, the first electrode 21 and the second electrode 22 need to be fed with alternating current, and then the system passes through The voltage is adjusted to switch to a low voltage electric field, and the AC frequency is adjusted to switch to a high frequency magnetic field.

According to some embodiments of the present invention, in addition to the information on the type of pollutant, the information on the pollutant also includes information on the content of the pollutant corresponding to the type of pollutant. The system can determine the continuous power-on time of the first electrode 21 and the second electrode 22 according to the pollutant content of the pollutant type in the filtered water, and control the first electrode 21 and the second electrode 22 within the above-mentioned continuous power-on time. Power on to maintain the low-voltage electric field for continuous sterilization within the above-mentioned continuous power-on time, or maintain the high-frequency magnetic field to continuously inhibit scale within the above-mentioned continuous power-on time.

In this way, the sterilization time or scale inhibition time of the first electrode 21 and the second electrode 22 is determined by the content of pollutants, so that the cleaning process of the filter element 1 can be monitored and controlled more accurately, and the waste of electric energy can be avoided, thereby saving energy and reducing costs.

In one embodiment of the present invention, the type of pollutant is determined to be microorganisms, and the step of controlling the first electrode 21 and the second electrode 22 to form a low-voltage electric field in the filter element 1 for sterilization specifically includes:

Determine the type of pollutant as microorganisms, adjust the voltage of the first electrode 21 and the second electrode 22 to the set voltage range to form a low-voltage electric field, and control the first electrode 21 and the second electrode according to the pollutant content information of microorganisms in the filtered water 22. Maintain the low-voltage electric field for a first set period of time.

In this embodiment, the set voltage range usually adopts a voltage range lower than 36V. For example, if the type of pollutant is determined to be microorganisms, adjust the voltage of the first electrode 21 and the second electrode 22 to below 36V and maintain the first set duration .

It can be understood that when the proportion of microorganisms in the filtered water is larger, the specific value of the first set time length is also greater; when the proportion of microorganisms in the filtered water is smaller, the specific value of the first set time length is also greater. smaller.

In another embodiment of the present utility model, the step of determining the type of pollutant as scale, and controlling the first electrode 21 and the second electrode 22 to form a high-frequency magnetic field in the filter element 1 to suppress the generation of scale specifically includes:

It is determined that the type of pollutant is scale, and the first electrode 21 and the second electrode 22 are controlled to pass through the alternating current within the set frequency range to form a high-frequency magnetic field; and according to the pollutant content information of the scale in the filtered water, control the first The electrodes 21 and the second electrodes 22 maintain the high-frequency magnetic field for a second set time period.

In this embodiment, setting the frequency range generally refers to controlling the magnetic field range to an alternating current frequency range above 6000 Hz, for example, to determine that the type of pollutant is microorganisms, and to pass alternating current to the first electrode 21 and the second electrode 22 so that The frequency of the magnetic field is above 6000 Hz and maintained for a second set time.

It can be understood that when the proportion of scale in the filtered water is larger, the specific value of the second set time length is also larger; when the proportion of scale in the filtered water is smaller, the specific value of the second set time length is also larger. smaller.

In yet another embodiment of the present utility model, in the step of controlling the electric field and magnetic field formed by the first electrode 21 and the second electrode 22 to switch between a low-voltage electric field and a high-frequency magnetic field according to the type of pollutants, it specifically includes:

After determining that the types of pollutants are microorganisms and scale, based on the pollutant content information of the microorganisms and scale in the filtered water, the first electrode 21 and the second electrode 22 are first controlled to generate a low-voltage electric field and maintain a third set duration for sterilization. Then control the first electrode 21 and the second electrode 22 to generate a high-frequency magnetic field and maintain it for a fourth set period of time to suppress the generation of scale.

In this embodiment, when the pollutants in the filtered water contain both microorganisms and scale, since the microorganisms are easily eliminated by the low-voltage electric field, and the scale can only be suppressed under the action of the high-frequency magnetic field, the system needs to give priority to the use of low-voltage The electric field sterilizes microorganisms, and then extends the duration of the high-frequency magnetic field for continuous and uninterrupted scale inhibition. In this way, the filter element 1 can be cleaned more efficiently by prioritizing the treatment of microorganisms and then the scale inhibition treatment, ensuring the cleaning and purification effect of the system on the filter element 1 and filtered water.

In a specific embodiment, when it is determined that the types of pollutants are microorganisms and scale, after the system feeds alternating current into the first electrode 21 and the second electrode 22, first adjust the voltage of the first electrode 21 and the second electrode 22 to 36V Below and maintain the third set time length, so that the low-voltage electric field is sterilized within the third set time length, then adjust the AC frequency so that the magnetic field frequency is above 6000HZ, and maintain the fourth set time length, so that the high-frequency magnetic field 4. Suppress scale generation within a set period of time.

The above-described embodiment realizes irregular intelligent cleaning by monitoring the specific content of pollutants in the filter element 1. The filter element cleaning method proposed by the utility model can also preset a specific cleaning frequency, and perform regular cleaning on the filter element 1 according to the cleaning frequency. Cleaning, specific examples will be introduced below. It should be noted that the following embodiment of regularly cleaning the filter element 1 can be combined with the above embodiment of judging the type of pollutants to switch the low-voltage electric field or high-frequency magnetic field, that is, the controller can judge the pollution. After specifying the type, the filter element 1 is regularly cleaned by using a specific electric field and magnetic field type and according to a specific cleaning frequency.

In one embodiment, the controller can clean the filter element 1 every certain amount of filtered water. Specifically, the step of controlling the cleaning agent to flow through and clean the filter element 1 includes: determining that the amount of water filtered by the filter element 1 reaches a preset filtered water amount , to pass electricity into the first electrode 21 and the second electrode 22 .

The execution steps proposed in this embodiment are generally applicable to the scenario where the type of pollutant is scale, because the formation of scale is closely related to factors such as the TDS of filtered water and the total amount of filtered water. At this time, the type of electric field and magnetic field formed in the filter element 1 is a high-frequency magnetic field.

Wherein, the aforementioned preset filtered water volume may be obtained in the following manner: acquiring the incoming water TDS of the filtered water, and determining the preset filtered water volume according to the incoming water TDS. For example, the controller obtains the incoming TDS of filtered water based on the sensor module, and then substitutes this TDS value into the water consumption corresponding to different TDS ranges (the relationship between the TDS range and water consumption can be obtained from experiments or experience), so as to determine the preset filtration value. The specific size of the water volume.

Of course, the utility model does not specifically limit the specific size of the preset filtered water volume, and the preset filtered water volume can also be obtained according to the default setting of the system or the user's own setting.

In another embodiment, the controller can clean the filter element 1 every certain filtering time. Specifically, the step of controlling the cleaning agent to flow through and cleaning the filter element 1 includes: determining that the working time of the filter element 1 reaches the preset filtering time, Electricity is supplied to the first electrode 21 and the second electrode 22 .

The execution steps proposed in this embodiment are generally applicable to scenarios where the type of pollutant is microorganisms, because the formation of microorganisms is closely related to factors such as time, and the type of electric field and magnetic field formed in the filter element 1 at this time is a low-voltage electric field. In addition, this embodiment does not specifically limit the specific size of the preset filtering duration, and the preset filtering duration can be acquired according to the default setting of the system or set by the user.

According to some embodiments of the present utility model, the "filtered water information" in the "filtered water information filtered according to the filter element 1" in step 100 may include the incoming water TDS, outgoing water TDS, incoming water flow, outgoing water flow and water temperature of the filtered water "Pollutant information" can include information such as the type and content of pollutants. Specifically, the controller can obtain the above pollutant information by analyzing and calculating the filtered water information.

According to an embodiment of the present invention, according to the filtered water information filtered by the filter element 1, the step of obtaining the pollutant information remaining in the filter element 1 specifically includes:

Obtain the first filtered water information of the filter element 1 in the initial use state, and obtain the second filtered water information of the filter element 1 in the current use state;

determining the pollutant type and/or the pollutant content corresponding to the pollutant type according to the comparison result of the first filtered water information and the second filtered water information;

Wherein, both the first filtered water information and the second filtered water information include the desalination rate and the effluent flow rate of the filtered water after passing through the filter element 1 . In addition, both the first filtered water information and the second filtered water information may also include information such as water temperature, which is not specifically limited here.

In this embodiment, the first filtered water information can indirectly represent the ideal working state of the filter element 1 without clogging (such as the first use of the filter element 1), and the second filtered water information can indirectly represent the current state of the filter element 1 after clogging occurs. Working state, therefore, the controller can determine the pollutant type and clogging degree of the filter element 1 under the current working state by comparing, analyzing and calculating the first filtered water information and the second filtered water information, and the filter element 1 The degree of clogging can indirectly reflect the content of pollutants.

It can be understood that, taking the water outlet flow as an example, the water outlet flow can reflect the degree of clogging of the filter element 1. Specifically, if the water inlet flow is the same, the water outlet flow value in the first filtered water information is different from the second filtered water information. The effluent flow values in are basically the same, which proves that the filter element 1 is not clogged in the current working state, that is, the pollutant content is low; if the influent flow is the same, the effluent flow value in the first filtered water information is greater than The effluent flow value in the second filtered water information proves that the filter element 1 is clogged in the current working state, that is, the pollutant content is relatively high. In particular, if the difference between the output water flow value in the second filtered water information and the output water flow value in the first filtered water information is greater, it proves that the filter element 1 is clogged more severely, that is, the pollutant content is higher.

The specific analysis of the process of judging the type of pollutants is similar to the above-mentioned principle of the process of judging the degree of clogging, and will not be repeated here.

According to an embodiment of the present invention, the filter element cleaning method of the water purification equipment also includes:

Obtain the third filtered water information of the filter element 1 before cleaning and the fourth filtered water information of the filter element 1 after cleaning;

According to the comparison result of the third filtered water information and the fourth filtered water information, it is judged whether a cleaning failure occurs in the water purification equipment, and if it is determined that a cleaning failure occurs, a failure reminder is issued;

Wherein, both the third filtered water information and the fourth filtered water information include the desalination rate and the effluent flow rate of the filtered water after flowing through the filter element 1 . In addition, the third filtered water information and the fourth filtered water information may both include information such as water temperature, which is not specifically limited here.

In this embodiment, the third filtered water information can indirectly represent the working state of the filter element 1 before cleaning, and the second filtered water information can indirectly represent the working state of the filter element 1 after cleaning. Therefore, the controller passes the first filtered water information and the second filtered water information are compared, analyzed and calculated to determine whether the current cleaning process of the filter element 1 is valid. The alarm device can issue a fault reminder to remind the user to perform maintenance and inspection on the water purification equipment in time. The alarm device can be installed inside the water purification equipment or on a remote console, and there is no special limitation here.

It can be understood that, taking the water outlet flow as an example, the water outlet flow can reflect the clogging degree of the filter element 1. Specifically, if the water inlet flow is the same, the water outlet flow value in the third filtered water information is smaller than the fourth filtered water flow. The output water flow value in the information proves that the current cleaning process of the filter element 1 is effective (that is, the water purification equipment does not have a cleaning failure); if the inflow flow is the same, the output water flow value in the first filtered water information and The output water flow values in the second filtered water information are basically the same, which proves that the current cleaning process of the filter element 1 is invalid (that is, the water purification equipment has a cleaning failure), and the alarm device will issue a failure reminder at this time.
