[0002] With the continuous improvement of living standards, people's demand for water quality is also increasing. Therefore, household electrical appliances such as water purifiers and water heaters are generally equipped with filter cores to ensure that the water quality meets the high standard requirements of users.

[0003] In order to maintain the purification efficiency of the filter core, regular cleaning of the filter core is essential. Traditionally, filter core cleaning mainly uses water flushing, that is, using water flow to flush the surface of the filter core to remove accumulated dirt and impurities. This method will cause a certain waste of water resources, and in the case of insufficient water pressure, the cleaning effect will be significantly reduced. Currently, ultrasonic cleaning technology is widely used in the cleaning process of the filter core. Compared with the traditional water flushing method, ultrasonic cleaning can more efficiently remove dirt on the filter core and significantly improve the cleaning effect.

[0048] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0049] The cleaning control method of the filter element provided by the embodiments of the present application can be applied to electrical equipment. In an embodiment, as shown in Figure 1As shown, the electric appliance includes a filter element 102 and a filter element cleaning device 104. The filter element 102 is used to access raw water and filter the raw water to output filtered clean water for users to take. The filter element cleaning device 104 is used to clean the filter element 102, and the filter element cleaning device 104 can be a device that uses an ultrasonic generator to clean (i.e., an ultrasonic filter element cleaning device) to efficiently remove dirt from the filter element 102. Exemplarily, the filter element cleaning device 104 can be arranged inside the filter element 102 to improve the cleaning effect.

[0050] In actual implementation, the electric appliance further includes a controller 106, which is electrically connected with the filter element cleaning device 104. The controller 106 is used to obtain a filter element cleaning instruction, obtain a water amount parameter of the filter element 102 of the electric appliance, and determine an internal water amount of the filter element 102 according to the water amount parameter. A filter element cleaning signal is issued based on the internal water amount of the filter element 102. The filter element cleaning signal is used to control the operating state of the filter element cleaning device 104 of the electric appliance.

[0051] It can be understood that the electric appliance further includes a water inlet assembly communicating with a water inlet end of the filter element 102. The water inlet assembly is electrically connected with the controller 106. Under the control of the controller 106, the water inlet assembly adjusts the water flow of the raw water flowing into the filter element 102. When the controller 106 controls the water inlet assembly to be turned off, no raw water enters the filter element 102.

[0052] The electric appliance further includes a water outlet pipeline, which communicates with a water outlet end of the filter element 102. The water outlet pipeline is provided with a clean water electromagnetic valve electrically connected with the controller 106. After the clean water electromagnetic valve is opened, the water filtered by the filter element 102 is output to the outside through the water outlet pipeline for users to take.

[0053] Since the opening degree of the clean water electromagnetic valve can reflect the water flow parameter in the water outlet pipeline, the controller 106 can obtain the feedback value of the clean water electromagnetic valve and determine the water flow parameter in the water outlet pipeline accordingly, so as to monitor the water flow state in the water outlet pipeline. Monitoring the water flow state in the water outlet pipeline is beneficial to the realization of filter element control and water quality monitoring functions.

[0054] The water outlet pipeline is further provided with a pressure switch electrically connected with the controller 106. The pressure switch can detect the water pressure change in the water outlet pipeline and output the water pressure parameter in the water outlet pipeline to the controller 106, so that the controller 106 can monitor the water pressure parameter in the water outlet pipeline. When the water pressure in the water outlet pipeline is abnormal (e.g., too high or too low), the controller 106 can take corresponding measures in time. For example, a fault warning can be issued to remind the user to check the filter element or the water outlet pipeline.

[0055] In one embodiment, the water amount parameter of the filter cartridge includes a water pressure parameter and a water flow parameter in the water outlet pipeline; the controller 106 is further configured to determine the internal water amount of the filter cartridge 102 according to the water pressure parameter and the water flow parameter in the water outlet pipeline. The manner in which the controller 106 determines the internal water amount of the filter cartridge according to the water pressure parameter and the water flow parameter in the water outlet pipeline is not limited, and can be set by referring to the common techniques in the art.

[0056] Since the water outlet pipeline of the electrical equipment is usually equipped with a pressure switch and a clean water electromagnetic valve, in the present embodiment, the feedback parameters of the two components are used to determine the internal water amount of the filter cartridge 102. This method does not need to introduce new detection components, nor does it need to make structural improvements to the equipment, thereby avoiding the increase in cost.

[0057] In other embodiments, the electrical equipment can further include a water amount detection component electrically connected to the controller 106, which can be a flow meter or a weight sensor arranged inside the filter cartridge 102. The water amount detection component is configured to detect a water amount parameter (such as a water flow parameter or a weight parameter inside the filter cartridge 102) of the filter cartridge 102 and transmit it to the controller 106, so that the controller 106 determines the internal water amount of the filter cartridge 102 according to the water amount parameter. This way, since the internal parameter of the filter cartridge 102 is directly monitored, the detection result of the internal water amount is more reliable.

[0058] In one exemplary embodiment, as shown in Figure 2 , a cleaning control method of a filter cartridge is provided, which is applied to the controller 106 in Figure 1 for example, and includes the following steps 202 to 206. Among them:

[0059] Step 202, obtaining a filter cartridge cleaning instruction.

[0060] In one embodiment, the filter cartridge cleaning instruction can be an instruction issued by the user. Exemplarily, the electrical equipment further includes an interactive module electrically connected to the controller, and the user can issue the filter cartridge cleaning instruction through the interactive module. In some embodiments, the interactive module can include a key, a touch screen, etc. In other embodiments, the interactive module can further include a wireless communication module, so that the controller can be communicatively connected with a terminal device (such as a smart phone, a wearable device, etc.) of the user, and receive the filter cartridge cleaning instruction issued by the user through the terminal device, thereby improving the use convenience of the electrical equipment.

[0061] In another embodiment, the filter cartridge cleaning instruction can also be an instruction generated inside the controller. Exemplarily, as shown in Figure 3 , the cleaning control method of the filter cartridge can further include steps 301 and 302.

[0062] At step 301, the cleaning interval duration of the filter element is obtained.

[0063] The cleaning interval duration is the duration from the time when the filter element cleaning device completes the last cleaning to the current time.

[0064] At step 302, the filter element cleaning instruction is generated when the cleaning interval duration of the filter element reaches the preset duration threshold.

[0065] During the use of the filter element, the controller continuously monitors the cleaning interval duration of the filter element, i.e., the duration from the time when the filter element cleaning device completes the last cleaning to the current time. When the cleaning interval duration reaches the preset duration threshold, it is determined that the filter element has accumulated enough impurities or dirt and needs to be cleaned, thereby generating the filter element cleaning instruction.

[0066] The preset duration threshold can be set in various ways. It can be a default value based on a general standard. It can also be set individually by the user or a professional according to specific conditions such as local water quality and filter element performance. It can also be dynamically adjusted by the controller based on the user's usage habits or real-time monitoring of water quality parameters and other information.

[0067] In this way, the user does not need to intervene, and the automation and intelligence of the filter element cleaning are achieved. Moreover, the problem of insufficient filter element cleaning due to human negligence can be avoided, and the filter element can be cleaned in time when it needs to be cleaned, thereby ensuring the water quality provided to the user.

[0068] At step 204, the water quantity parameter of the filter element of the electric device is obtained, and the internal water quantity of the filter element is determined based on the water quantity parameter.

[0069] The controller can obtain the water quantity parameter of the filter element of the electric device in various ways. For example, the water quantity parameter of the filter element includes the water pressure parameter and the water flow parameter in the water outlet pipeline, and the controller obtains the water pressure parameter and the water flow parameter in the water outlet pipeline through the pressure switch and the water purification electromagnetic valve in the water outlet pipeline. Then, the internal water quantity of the filter element is calculated based on the water pressure parameter and the water flow parameter in the water outlet pipeline.

[0070] In some embodiments, after obtaining the filter element cleaning instruction, the controller obtains the water outlet parameter of the filter element at the current time, and determines the internal water quantity of the filter element based on the water outlet parameter of the filter element at the current time. This way is fast in response and high in control efficiency.

[0071] In some embodiments, the controller, after obtaining the filter cleaning instruction, obtains the water outlet parameters of the plurality of filters (such as the water pressure parameters and the water flow parameters in the water outlet pipeline at multiple time points), and determines the internal water amount of the filter based on the water outlet parameters of the plurality of filters. In this way, the internal water amount of the filter can be determined more accurately, and the situation that the internal water amount is determined incorrectly due to inaccurate detection of the water outlet parameter at a single time point can be effectively avoided.

[0072] At step 206, a filter cleaning signal is sent based on the internal water amount of the filter.

[0073] The filter cleaning signal is used to control the operating state of the filter cleaning device.

[0074] The controller determines the filter cleaning signal according to the internal water amount of the filter, so as to control the filter cleaning device based on the filter cleaning signal.

[0075] The operating state of the filter cleaning device can include the on operating state of the ultrasonic generator in the filter cleaning device.

[0076] The filter cleaning signal can trigger the ultrasonic generator in the filter cleaning device to start operating. During the operation of the ultrasonic generator, the water in the filter plays a dual role: on the one hand, it acts as a cleaning liquid to effectively remove dirt on the surface of the filter, ensuring the cleaning effect of the filter; on the other hand, it also plays a role in carrying away heat, preventing the heat generated by the ultrasonic generator from causing the temperature of the filter to be too high, thereby protecting the filter from damage.

[0077] The controller controls the on operating state of the filter cleaning device according to the internal water amount of the filter, so as to ensure that the water amount in the filter can control the heat generated by the filter cleaning device, thereby effectively protecting the filter.

[0078] The operating state of the filter cleaning device can also include the power state of the ultrasonic generator in the filter cleaning device.

[0079] The controller controls the power state of the on operating state of the filter cleaning device according to the internal water amount of the filter. Thus, the heat generated during the operation of the filter cleaning device can be effectively controlled by the water amount in the filter, so that the temperature of the filter does not rise excessively, thereby effectively protecting the filter.

[0080] The operating state of the filter cleaning device can also include the operation duration of the ultrasonic generator in the filter cleaning device. Thus, the filter can not be excessively heated due to too long cleaning time, thereby achieving the purpose of protecting the filter.

[0081] The cleaning control method of the filter element includes obtaining a filter element cleaning instruction; obtaining a water amount parameter of the filter element of the electrical equipment, and determining an internal water amount of the filter element according to the water amount parameter; issuing a filter element cleaning signal based on the internal water amount of the filter element; the filter element cleaning signal is used to control an operation state of a filter element cleaning device of the electrical equipment; and the filter element cleaning device is used to clean the filter element. In this way, the operation state of the filter element cleaning device can be regulated according to the actual water amount in the filter element, so that the heat generated by the filter element cleaning device can be effectively controlled, and the temperature of the filter element cannot be excessively high. Therefore, the cleaning effect of the filter element is achieved, the filter element is protected, and the use reliability of the electrical equipment is improved.

[0082] In one embodiment, step 206 can include: in a case where the internal water amount of the filter element is greater than or equal to a preset cleaning water amount threshold, issuing a filter element cleaning signal.

[0083] In this embodiment, in a case where the internal water amount of the filter element is greater than or equal to the preset cleaning water amount threshold, the ultrasonic generator in the filter element cleaning device is controlled to start operation, so that the cleaning effect of the filter element can be ensured, and the heat generated by the filter element cleaning device can be controlled by the sufficient water amount in the filter element, and the filter element is effectively protected. The preset cleaning water amount threshold needs to be set according to specific conditions, and this embodiment does not limit this.

[0084] In one embodiment, step 206 can further include:

[0085] in a case where the internal water amount of the filter element is less than the preset cleaning water amount threshold, issuing a water adding instruction;

[0086] in a case where the internal water amount of the filter element is greater than or equal to the preset cleaning water amount threshold, issuing a filter element cleaning signal.

[0087] The water adding instruction is used to control the water inlet assembly of the electrical equipment to increase the raw water flow. The water inlet assembly is connected to the water inlet end of the filter element, and is used to control the water flow of the raw water flowing into the filter element.

[0088] When the internal water amount of the filter element is insufficient (i.e., less than the preset cleaning water amount threshold), if the filter element cleaning device is controlled to start operation, the water in the filter element cannot effectively control the heat, and the filter element can be damaged due to the excessively high temperature of the filter element. Moreover, the insufficient water amount cannot achieve the expected cleaning effect, and resources are wasted.

[0089] In this embodiment, when the internal water amount of the filter core is less than the preset cleaning water amount threshold, the controller issues a water adding instruction to trigger the water inlet assembly to increase the raw water flow to increase the water amount inside the filter core until the internal water amount of the filter core reaches or exceeds the preset cleaning water amount threshold. When the controller monitors that the internal water amount of the filter core is large enough (i.e., greater than or equal to the preset cleaning water amount threshold), a filter core cleaning signal is issued to trigger the ultrasonic generator in the filter core cleaning device to start operating.

[0090] Therefore, when the internal water amount of the filter core is insufficient, the controller can automatically adjust the flow of the water inlet assembly, and through the automatic water adding process, the intelligent degree of the filter core cleaning function is improved, and thus the use convenience of the electrical equipment is improved. Moreover, the risk of poor cleaning effect or damage to the filter core due to insufficient water amount can be avoided, and thus the use reliability of the electrical equipment is improved.

[0091] In some embodiments, step 206 can include determining the cleaning power of the filter core cleaning device according to the internal water amount of the filter core; and issuing the filter core cleaning signal based on the cleaning power.

[0092] In this embodiment, the cleaning power of the filter core cleaning device includes the operating power value or operating power range of the ultrasonic generator. After determining the internal water amount of the filter core, the controller determines the heat control capability that can be achieved according to the internal water amount of the filter core, and determines the cleaning power of the filter core cleaning device accordingly.

[0093] The filter core cleaning signal issued based on the cleaning power can trigger the ultrasonic generator in the filter core cleaning device to operate at a suitable operating power value or operating power range. Therefore, the heat generated during the operation of the filter core cleaning device can be effectively controlled by the water amount inside the filter core, so that the temperature of the filter core does not rise excessively, thereby effectively protecting the filter core.

[0094] It can be understood that in actual implementation, the controller can also determine the heat control capability and cleaning capability that can be achieved according to the internal water amount of the filter core, and comprehensively determine the cleaning power of the filter core cleaning device accordingly, so as to take into account the temperature rise and cleaning effect of the filter core.

[0095] In some embodiments, step 206 can include determining the cleaning power and operating duration of the filter core cleaning device according to the internal water amount of the filter core; and issuing the filter core cleaning signal based on the cleaning power and operating duration.

[0096] In this embodiment, after determining the internal water amount of the filter core, the controller determines the heat control capability that can be achieved according to the internal water amount of the filter core, and determines the cleaning power and operating duration of the filter core cleaning device accordingly. Therefore, the dirt can be effectively removed, and the filter core is not excessively heated due to long cleaning time, thereby achieving the purpose of protecting the filter core.

[0097] In one embodiment, as shown in FIG. 20, after step 206, the filter cleaning control method further includes steps 402, 404 and 406. Figure 4

[0098] In step 402, in the case of receiving a stop cleaning instruction, a stop cleaning signal is sent according to the stop cleaning instruction.

[0099] The stop cleaning signal is used to control the filter cleaning device to stop working.

[0100] The stop cleaning instruction can be an instruction issued by the user, such as a stop cleaning instruction issued by the user through the interaction module. Illustratively, the stop cleaning instruction issued by the user can directly instruct to stop the current cleaning operation, and when the controller receives the stop cleaning instruction, a stop cleaning signal is immediately sent to trigger the filter cleaning device to stop working.

[0101] The stop cleaning instruction issued by the user can also include a reservation end duration parameter. When the controller receives the stop cleaning instruction including the reservation end duration parameter, the specific time to stop cleaning is calculated according to the reservation end duration parameter, and once the time is reached, the controller will immediately send a stop cleaning signal to trigger the filter cleaning device to stop all cleaning-related operations. The reservation end duration parameter can be flexibly set by the user, and the shortest can be 0, i.e. to stop the cleaning operation immediately. Thus, a more personalized stop cleaning control method is provided for the user, improving the use convenience of the electrical equipment.

[0102] The stop cleaning instruction can also be an instruction generated internally by the controller. In some embodiments, the controller generates a stop cleaning instruction when the filter cleaning signal is sent to reach the target cleaning duration.

[0103] In actual implementation, when the filter cleaning signal sent by the controller triggers the filter cleaning device to start running, the start time is also recorded, and the continuous running duration of the filter cleaning device for this cleaning, i.e. the cleaning continuous duration, is recorded based on the start time. Once the cleaning continuous duration reaches or exceeds the target cleaning duration, the controller will automatically generate a stop cleaning instruction, and then send a stop cleaning signal.

[0104] The stop cleaning signal sent by the controller can trigger the filter cleaning device to stop cleaning, ensuring the controllability and accuracy of the cleaning process. At the same time, it can avoid damage to the filter or waste of energy due to too long cleaning time.

[0105] ​The target cleaning duration can be set in multiple ways. In some embodiments, the target cleaning duration can be a default value preset by the system. For example, a fixed value set according to the performance of the filter element is used as the default value. This way of using a preset default value as the target cleaning duration does not require manual setting by the user, and the intelligence level of the filter element cleaning function is high. In some embodiments, the user can also set the target cleaning duration through the interaction module according to the local water quality, actual needs, and use preferences, etc. For example, the user can specify the target cleaning duration in the filter element cleaning instruction issued. This way can meet the specific needs of the user and improve the cleaning effect and user satisfaction. In some embodiments, the controller can dynamically calculate and generate the target cleaning duration. For example, the controller can generate the target cleaning duration according to the filter element performance and the cleaning interval duration, etc. By accurately controlling the cleaning duration, the filter element can be effectively protected, and its service life can be prolonged.

[0106] In some embodiments, the controller can also issue a stop cleaning instruction when it is detected that the internal water amount of the filter element is lower than the preset cleaning water amount threshold. Thus, the cleaning effectiveness of the cleaning process and the safety of the filter element can be ensured.

[0107] At step 404, the continuous running duration of the filter element cleaning device is obtained.

[0108] At step 406, if the continuous running duration is less than the target cleaning duration, a cleaning duration insufficient prompt is issued.

[0109] It can be understood that in actual application, the cleaning process can be interrupted in advance due to user intervention or other external factors. Therefore, after the filter element cleaning device is controlled to stop, the controller judges whether the continuous running duration of the current cleaning reaches the target cleaning duration. If the continuous running duration does not reach the target cleaning duration, a cleaning duration insufficient prompt is issued.

[0110] The cleaning duration insufficient prompt can be presented to the user in multiple ways, such as being directly displayed on the display screen in the interaction module, being prompted by flashing or color change of the indicator light, being played by the sound module, or being sent to the terminal device of the user.

[0111] In this embodiment, the cleaning duration insufficient prompt is issued in a timely manner, so that the user can fully understand the completion of the current cleaning, which helps to improve the reliability of the electrical equipment.

[0112] In one embodiment, the filter element cleaning control method further includes:

[0113] obtaining a cleaning interval duration of the filter element;

[0114] determining the target cleaning duration according to the cleaning interval duration.

[0115] The cleaning interval length is a length of time from a previous cleaning time point to a current time point at which the filter core cleaning device completes cleaning. The cleaning interval length represents a length of time that the filter core remains in a non-cleaning state between two consecutive cleanings, and can reflect a cumulative contamination degree of the filter core. The current time point can be a time point at which the filter core cleaning instruction is received, or a time point at which the controller sends the filter core cleaning signal, that is, a time point at which the cleaning operation officially starts.

[0116] The manner of determining the target cleaning length according to the cleaning interval length is not unique. In some embodiments, determining the target cleaning length according to the cleaning interval length can include:

[0117] In a case where the cleaning interval length is greater than the filter core working length threshold, the target cleaning length is determined as a first length; in a case where the cleaning interval length is less than or equal to the filter core working length threshold, the target cleaning length is determined as a second length.

[0118] The first length is greater than the second length. The filter core working length threshold can be set according to specific circumstances.

[0119] When the cleaning interval length exceeds the filter core working length threshold, it can be considered that the filter core has not been cleaned for a long time and has accumulated a large amount of pollutants. Therefore, a relatively long target cleaning length, that is, the first length, is determined to ensure that the pollutants on the filter core can be sufficiently removed and the filtering performance of the filter core can be restored.

[0120] If the cleaning interval length is less than or equal to the filter core working length threshold, the interval time from the last cleaning of the filter core is short, and it is considered that the contamination degree of the filter core is relatively low. Therefore, a relatively short target cleaning length, that is, the second length, is determined to avoid resource waste and filter core loss caused by excessive cleaning.

[0121] In this embodiment, the target cleaning length is determined in combination with the actual cleaning interval length of the filter core, which can more accurately match the actual cleaning needs of the filter core. Therefore, the cleaning efficiency can be improved, and the service life of the filter core can be effectively prolonged.

[0122] In some embodiments, determining the target cleaning length according to the cleaning interval length can include:

[0123] The cleaning duration length corresponding to the cleaning interval length is matched according to a preset corresponding relationship.

[0124] The preset corresponding relationship can be obtained based on experimental data, experience summary or algorithm optimization, and can reflect a cleaning duration length required by the filter core under different cleaning interval lengths. The preset corresponding relationship can be a relational expression, or a grade classification table, etc.

[0125] When it is necessary to determine the target cleaning duration, the controller first acquires the current cleaning interval duration, and then matches a corresponding cleaning duration according to the preset correspondence relationship, and takes it as the target cleaning duration. Since the correspondence relationship can better reflect the actual cleaning demand of the filter core under different cleaning interval durations, the target cleaning duration matched based thereon can better match the actual cleaning demand of the filter core, thereby improving the efficiency and accuracy of the cleaning control.

[0126] Further, when the controller controls the filter core cleaning device to stop working, in the case that the continuous running duration is less than the target cleaning duration, the controller further records a duration difference value between the target cleaning duration and the continuous running duration. In some embodiments, determining the target cleaning duration according to the cleaning interval duration can include:

[0127] Determining the target cleaning duration according to the cleaning interval duration and the duration difference value.

[0128] In the determination of the target cleaning duration according to the cleaning interval duration and the duration difference value, the sum of the cleaning interval duration and the duration difference value can be taken as a whole, and the method in the above embodiments can be adopted to compare the sum with the filter core working duration threshold, and determine the first duration and the second duration as the target cleaning duration. The corresponding cleaning duration can also be matched according to the sum and the preset correspondence relationship.

[0129] Since the duration difference value reflects the degree to which the previous cleaning operation does not complete the predetermined task, i.e., the degree to which the cleaning of the filter core does not achieve the target cleaning effect, the closed-loop detection of the filter core cleaning state is realized. In the subsequent determination of the target cleaning duration, the target cleaning duration is comprehensively determined according to the current cleaning interval duration and the previously recorded duration difference value, which can ensure that the current cleaning can make up for the insufficient cleaning of the previous cleaning, thereby improving the cleaning quality.

[0130] In order to better understand the above embodiments, the following will be explained in detail in combination with an optional embodiment. In one embodiment, please refer to Figure 5 The cleaning control method of the filter core includes:

[0131] Receiving the filter core cleaning instruction issued by the user, opening the pressure switch and the water purification electromagnetic valve in the water outlet pipeline, and receiving the feedback values (i.e., the water pressure parameter and the water flow parameter in the water outlet pipeline) returned by the pressure switch and the water purification electromagnetic valve.

[0132] Determining whether the internal water amount A of the filter core reaches the preset cleaning water amount threshold a according to the feedback values returned by the pressure switch and the water purification electromagnetic valve. Specifically, if the feedback value B of the pressure switch is greater than the preset pressure threshold b and the feedback value Q of the water purification electromagnetic valve is greater than the preset flow valve threshold q, it is determined that the internal water amount A of the current filter core is greater than the preset cleaning water amount threshold a, and the ultrasonic filter core cleaning device can be started.

[0133] If the feedback value B of the pressure switch is not greater than the preset pressure threshold b and the feedback value Q of the water purification electromagnetic valve is not greater than the preset flow threshold q, it is determined that the current water amount A in the filter core is less than the preset cleaning water amount threshold a, the ultrasonic filter core cleaning device cannot be started, and the ultrasonic filter core cleaning device can be started only after the conditions are met.

[0134] After it is detected that the ultrasonic filter core cleaning device can be started, the target cleaning duration of the ultrasonic filter core cleaning device (that is, the working duration of the ultrasonic generator) is determined. Specifically, the cleaning interval duration T of the filter core is first obtained, and the cleaning interval duration T of the filter core is compared with the working duration threshold t of the filter core. If the cleaning interval duration T of the filter core is greater than the working duration threshold t of the filter core, the working duration Tc of the ultrasonic generator is adapted to be the first duration time1, otherwise, the working duration Tc of the ultrasonic generator is adapted to be the second duration time2.

[0135] After the working duration Tc of the ultrasonic generator is determined, a filter core cleaning signal is immediately sent to trigger the ultrasonic filter core cleaning device to start working.

[0136] After receiving the stop cleaning instruction, a stop cleaning signal is sent to control the ultrasonic filter core cleaning device to stop working, so as to end the cleaning operation. At the same time, the controller also clears the cleaning interval duration T of the filter core, so as to prepare for the next filter core cleaning operation.

[0137] The above-mentioned filter core cleaning control method detects the internal water amount of the current filter core by combining the actions of the pressure switch and the water purification electromagnetic valve. If it is detected that the internal water amount of the filter core meets the conditions for starting the ultrasonic filter core cleaning device, the ultrasonic filter core cleaning device is started to work, and the filter core cleaning interval duration is automatically cleared after the cleaning operation is completed. If the water amount requirement is not met, the ultrasonic filter core cleaning device is stopped to work, so as to protect the filter core. At the same time, the different target cleaning durations are adapted according to the cleaning interval duration, so as to ensure that the filter core is effectively cleaned and the filter core cleaning effect is improved.

[0138] It should be understood that, although each step in the flowchart involved in each embodiment as described above is displayed in sequence according to the indication of the arrow, these steps are not necessarily executed in sequence according to the indication of the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences.

[0147] In one embodiment, the cleaning control module 606 is further configured to, in a case where the internal water amount of the filter core is greater than or equal to a preset cleaning water amount threshold, issue the filter core cleaning signal.

[0148] In an embodiment, the cleaning control module 606 is further configured to, in a case where the internal water amount of the filter element is less than the preset cleaning water amount threshold, send a water adding instruction, the water adding instruction being used to control the water inlet assembly of the use electric device to increase the raw water flow; the water inlet assembly being connected to the water inlet end of the filter element and being used to control the water flow of the raw water flowing into the filter element; and in a case where the internal water amount of the filter element is greater than or equal to the preset cleaning water amount threshold, send a filter element cleaning signal.

[0149] In an embodiment, the cleaning control module 606 is further configured to determine the cleaning power of the filter element cleaning device according to the internal water amount of the filter element; and send the filter element cleaning signal based on the cleaning power.

[0150] In an embodiment, the cleaning control module 606 is further configured to obtain a cleaning interval duration of the filter element, the cleaning interval duration being a duration from a previous cleaning time of the filter element cleaning device to a current time; and in a case where the cleaning interval duration of the filter element reaches a preset duration threshold, generate a filter element cleaning instruction.

[0151] The above-mentioned modules in the filter element cleaning control device can be realized by software, hardware and combinations thereof in whole or in part. The above-mentioned modules can be embedded in or independent of the processor in the computer device in hardware form, or can be stored in the memory in the computer device in software form, so as to be called and executed by the processor to perform the operations corresponding to the above-mentioned modules.

[0152] In an exemplary embodiment, a use electric device is provided. Please refer to Figure 1 The use electric device comprises a controller 106, a filter element 102 and a filter element cleaning device 104, the controller 106 being electrically connected to the filter element cleaning device 104; and the controller being used to realize the cleaning control of the filter element 102 based on the above-mentioned cleaning control method of the filter element according to the embodiments.

[0153] The filter element 102 is used to access raw water and filter the raw water to output filtered clean water for a user to take. The filter element cleaning device 104 is used to clean the filter element 102, and the filter element cleaning device 104 can be a device using an ultrasonic generator to clean (i.e. an ultrasonic filter element cleaning device) to efficiently remove dirt of the filter element 102. Exemplarily, the filter element cleaning device 104 can be arranged inside the filter element 102 to improve the cleaning effect.

[0154] The use electric device further comprises a water inlet assembly connected to the water inlet end of the filter element 102.

[0155] In an embodiment, the electric appliance further comprises a water outlet pipeline, which is in communication with the water outlet end of the filter element 102.

When the water pressure in the water outlet pipeline is abnormal (e.g., too high or too low), the controller 106 can take corresponding measures in time. For example, the controller 106 can issue a fault warning to remind the user to check the filter element or the water outlet pipeline.

[0158] In an embodiment, the water quantity parameter of the filter element comprises the water pressure parameter and the water flow parameter in the water outlet pipeline; and the controller 106 is further configured to determine the internal water quantity of the filter element 102 according to the water pressure parameter and the water flow parameter in the water outlet pipeline.
