Description

[0002] As living standards continue to improve, people's requirements for water quality are also increasing. Therefore, household electrical appliances such as water purifiers and water heaters are generally equipped with built-in filters to ensure that the water quality meets the high standards of users.

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

[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying 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 filter element cleaning control method provided in the embodiment of the present application can be applied to electrical equipment. Figure 1As shown, the electrical equipment includes a filter element 102 and a filter element cleaning device 104. The filter element 102 is used to receive raw water and filter the raw water to output filtered clean water for users to use. The filter element cleaning device 104 is used to clean the filter element 102. The filter element cleaning device 104 can be a device that uses an ultrasonic generator for cleaning (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 disposed inside the filter element 102 to improve the cleaning effect.

[0050] In actual implementation, the electrical equipment also includes a controller 106, which is electrically connected to the filter element cleaning device 104. The controller 106 is used to obtain filter element cleaning instructions; obtain water volume parameters of the filter element 102 of the electrical equipment, and determine the internal water volume of the filter element 102 according to the water volume parameters; issue a filter element cleaning signal based on the internal water volume 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 electrical equipment.

[0051] It can be understood that the electrical equipment further includes a water inlet assembly connected to the water inlet end of the filter element 102. The water inlet assembly is electrically connected to the controller 106. Under the control of the controller 106, the water inlet assembly adjusts the water flow rate 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 electrical equipment also includes a water outlet pipeline, which is connected to the water outlet end of the filter element 102. A water purification solenoid valve electrically connected to the controller 106 is provided in the water outlet pipeline. After the water purification solenoid valve is turned on, 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 of the water purification solenoid valve can reflect the water flow parameters in the water outlet pipeline, the controller 106 can obtain the feedback value of the water purification solenoid valve and determine the water flow parameters in the water outlet pipeline accordingly to monitor the water flow state in the water outlet pipeline. Monitoring the water flow state in the water outlet pipeline is conducive to the realization of functions such as filter element control and water quality monitoring.

[0054] A pressure switch electrically connected to the controller 106 is also provided in the water outlet pipeline. The pressure switch can detect the water pressure change in the water outlet pipeline and output the water pressure parameters in the water outlet pipeline to the controller 106, so that the controller 106 can monitor the water pressure parameters in the water outlet pipeline. When the water pressure in the water outlet pipeline is abnormal (such as 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 volume parameter of the filter element includes the water pressure parameter and the water flow parameter in the water outlet pipeline; the controller 106 is further used to determine the internal water volume of the filter element 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 volume of the filter element according to the water pressure parameter and the water flow parameter in the water outlet pipeline does not need to be limited, and those skilled in the art can make settings with reference to the commonly used techniques in the art.

[0056] Since the water outlet pipeline of the electrical equipment is usually equipped with a pressure switch and a water purification solenoid valve, in this embodiment, the feedback parameters of these two components are used to determine the internal water volume of the filter element 102. This method does not require the introduction of new detection components or structural improvements to the equipment, thereby avoiding cost increases.

[0057] In other embodiments, the electrical device may further include a water volume detection component electrically connected to the controller 106, and the water volume detection component may be a flow meter or a weight sensor or other components disposed inside the filter element 102. The water volume detection component is used to detect water volume parameters of the filter element 102 (such as water flow parameters and weight parameters inside the filter element 102), and transmit them to the controller 106, so that the controller 106 determines the internal water volume of the filter element 102 according to the water volume parameters. This method directly monitors the internal parameters of the filter element 102, making the detection result of the internal water volume more reliable.

[0058] In an exemplary embodiment, Figure 2 As shown, a filter element cleaning control method is provided, and the method is applied to Figure 1 The controller 106 in FIG. 1 is taken as an example to illustrate the method, which includes the following steps 202 to 206. Among them:

[0059] Step 202, obtaining filter element cleaning instructions.

[0060] In one embodiment, the filter cleaning instruction may be an instruction issued by the user. Exemplarily, the electrical device also includes an interactive module electrically connected to the controller, and the user can issue a filter cleaning instruction through the interactive module. In some embodiments, the interactive module may include components such as buttons and a touch screen. In other embodiments, the interactive module may also include a wireless communication module to enable the controller to communicate with the user's terminal device (such as a smart phone, wearable device, etc.) and receive the filter cleaning instruction issued by the user through the terminal device, thereby improving the convenience of using the electrical device.

[0061] In another embodiment, the filter element cleaning instruction may also be an instruction generated inside the controller. Figure 3 As shown, the filter element cleaning control method may further include step 301 and step 302.

[0062] Step 301, obtaining the cleaning interval duration of the filter element.

[0063] The cleaning interval is the time from the last time the filter cleaning device completed cleaning to the current time.

[0064] Step 302: When the cleaning interval of the filter element reaches a preset time threshold, a filter element cleaning instruction is generated.

[0065] During the use of the filter element, the controller will continuously monitor the cleaning interval of the filter element, that is, the time from the time the filter element cleaning device completed the previous cleaning to the current time. When the cleaning interval reaches the preset time threshold, it is determined that the filter element has accumulated enough impurities or dirt and needs to be cleaned, thereby generating a filter element cleaning instruction.

[0066] There is no unique way to set the preset time threshold. It can be a default value based on universal standards; it can also be personalized by users or professionals based on specific conditions (such as local water quality conditions and filter element performance); it can also be dynamically adjusted by the controller based on user usage habits or real-time monitored water quality parameters and other information.

[0067] As a result, the filter element cleaning is automated and intelligent without user intervention. Insufficient cleaning of the filter element due to human negligence can be avoided, so that the filter element can be cleaned in time when it needs to be cleaned, ensuring the water quality provided to the user.

[0068] Step 204, obtaining water volume parameters of the filter element of the electrical equipment, and determining the internal water volume of the filter element according to the water volume parameters.

[0069] There is no unique way for the controller to obtain the water volume parameters of the filter element of the electrical equipment. Exemplarily, the water volume parameters of the filter element include the water pressure parameters and water flow parameters in the water outlet pipeline. The controller obtains the water pressure parameters and water flow parameters in the water outlet pipeline through the pressure switch and the water purification solenoid valve in the water outlet pipeline. Then, the internal water volume of the filter element is calculated based on the water pressure parameters and water flow parameters in the water outlet pipeline.

[0070] In some embodiments, after obtaining the filter element cleaning instruction, the controller obtains the water output parameters of the filter element at the current moment, and determines the internal water volume of the filter element according to the water output parameters of the filter element at the current moment. This method responds quickly and has high control efficiency.

[0071] In other embodiments, after obtaining the filter element cleaning instruction, the controller will obtain the water outlet parameters of multiple filter elements (such as the water pressure parameters and water flow parameters in the water outlet pipeline at multiple times), and determine the internal water volume of the filter element based on the water outlet parameters of the multiple filter elements. This method can effectively avoid the situation where the internal water volume is misjudged due to inaccurate detection of water outlet parameters at a single time, and more accurately judge the internal water volume of the filter element.

[0072] Step 206 , issuing a filter element cleaning signal based on the internal water volume of the filter element.

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

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

[0075] The operating state of the filter element cleaning device may include an on-operating state of an ultrasonic generator in the filter element cleaning device.

[0076] The filter cleaning signal can trigger the ultrasonic generator in the filter cleaning device to start running. During the operation of the ultrasonic generator, the water inside the filter plays a dual role: on the one hand, it acts as a cleaning fluid to effectively remove dirt on the surface of the filter element and ensure the cleaning effect of the filter element; on the other hand, it also takes away heat to prevent the heat generated by the ultrasonic generator from causing the filter element to overheat and protect the filter element from damage.

[0077] The controller controls the start-up and operation state of the filter element cleaning device according to the internal water volume of the filter element, thereby ensuring that the water volume in the filter element is sufficient to control the heat generated by the filter element cleaning device, thereby effectively protecting the filter element.

[0078] The operating status of the filter element cleaning device may also include the power status of the ultrasonic generator in the filter element cleaning device.

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

[0080] The operating state of the filter element cleaning device may also include the operating time of the ultrasonic generator in the filter element cleaning device, so as to avoid excessive heating of the filter element due to too long cleaning time, thereby achieving the purpose of protecting the filter element.

[0081] The above-mentioned filter element cleaning control method includes obtaining a filter element cleaning instruction; obtaining a water volume parameter of a filter element of an electrical device, and determining the internal water volume of the filter element according to the water volume parameter; issuing a filter element cleaning signal based on the internal water volume of the filter element; the filter element cleaning signal is used to control the operating state of a filter element cleaning device of the electrical device; and the filter element cleaning device is used to clean the filter element. Thus, the operating state of the filter element cleaning device can be adjusted according to the actual water volume in the filter element, so that the heat generated by the filter element cleaning device can be effectively controlled and will not cause the temperature of the filter element to be too high. Thus, the filter element cleaning effect is achieved, and it helps to protect the filter element, thereby improving the reliability of the use of the electrical equipment.

[0082] In one embodiment, step 206 may include: when the amount of water inside 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, when the amount of water inside the filter element is greater than or equal to the preset cleaning water volume threshold, the ultrasonic generator in the filter element cleaning device is controlled to start running, which can not only ensure the cleaning effect of the filter element, but also ensure that there is enough water in the filter element to control the heat generated by the filter element cleaning device, thereby effectively protecting the filter element. Among them, the preset cleaning water volume threshold needs to be set according to the specific situation, and this is not limited in this embodiment.

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

[0085] When the internal water volume of the filter element is less than the preset clean water volume threshold, a water adding instruction is issued;

[0086] When the internal water volume of the filter element is greater than or equal to the preset cleaning water volume threshold, a filter element cleaning signal is issued.

[0087] The water adding instruction is used to control the water inlet component of the electrical equipment to increase the raw water flow. The water inlet component 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 water volume inside the filter element is insufficient (i.e., less than the preset cleaning water volume threshold), if the filter element cleaning device is turned on, the water inside the filter element cannot effectively control the heat, and the filter element may be damaged due to excessively high filter temperature. Moreover, insufficient water volume cannot achieve the expected cleaning effect, wasting resources.

[0089] In this embodiment, when the amount of water inside the filter element is less than the preset clean water threshold, the controller will issue a water adding instruction to trigger the water inlet component to increase the raw water flow rate to increase the amount of water inside the filter element until it is detected that the amount of water inside the filter element reaches or exceeds the preset clean water threshold. When the controller detects that the amount of water inside the filter element is large enough (i.e., greater than or equal to the preset clean water threshold), it will issue a filter element cleaning signal to trigger the ultrasonic generator in the filter element cleaning device to start running.

[0090] Therefore, when the water volume inside the filter element is insufficient, the controller can automatically adjust the flow rate of the water inlet assembly. Through the automated water adding process, the intelligence of the filter element cleaning function is improved, thereby improving the convenience of using the electrical equipment. It can also avoid the risk of poor cleaning effect or filter element damage caused by insufficient water, thereby improving the reliability of the electrical equipment.

[0091] In some embodiments, step 206 may include: determining the cleaning power of the filter element cleaning device according to the internal water volume of the filter element; and issuing a filter element cleaning signal based on the cleaning power.

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

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

[0094] It can be understood that in actual implementation, the controller can also determine the achievable heat control capacity and cleaning capacity based on the internal water volume of the filter element, and comprehensively determine the cleaning power of the filter element cleaning device based on this, thereby taking into account the temperature rise and cleaning effect of the filter element.

[0095] In some embodiments, step 206 may include: determining the cleaning power and operating duration of the filter element cleaning device according to the internal water volume of the filter element; and issuing a filter element cleaning signal based on the cleaning power and operating duration.

[0096] In this embodiment, after determining the internal water volume of the filter element, the controller will determine the heat control capacity that can be achieved according to the internal water volume of the filter element, and determine the cleaning power and operation time of the filter element cleaning device accordingly. In this way, the dirt can be removed effectively, and the filter element will not be overheated due to too long cleaning time, so as to achieve the purpose of protecting the filter element.

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

[0098] Step 402: When a stop cleaning instruction is received, a stop cleaning signal is issued according to the stop cleaning instruction.

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

[0100] The stop cleaning instruction may be an instruction issued by a user, such as a stop cleaning instruction issued by a user through an interactive module. For example, the stop cleaning instruction issued by a user may directly instruct to stop the current cleaning operation, and when the controller receives the stop cleaning instruction, it immediately sends a stop cleaning signal to trigger the filter element cleaning device to stop working.

[0101] The stop cleaning instruction issued by the user may also include a reservation end duration parameter. When the controller receives the stop cleaning instruction including the reservation end duration parameter, it calculates the specific time to stop cleaning based on the reservation end duration parameter. Once the time is reached, the controller will immediately send a stop cleaning signal to trigger the filter element cleaning device to stop all cleaning-related operations. The reservation end duration parameter can be flexibly set by the user, and its shortest value can be 0, which means that the cleaning operation stops immediately. This provides users with a more personalized stop cleaning control method and improves the convenience of using electrical equipment.

[0102] The stop cleaning instruction can also be an instruction generated inside the controller. In some embodiments, the controller generates a stop cleaning instruction when the filter element cleaning signal is sent and the target cleaning time is reached.

[0103] In actual implementation, when the controller sends out a filter cleaning signal to trigger the filter cleaning device to start running, it will also record the start time, and based on the start time, continuously record the duration of the current cleaning of the filter cleaning device, that is, the duration of the current cleaning. Once the cleaning duration reaches or exceeds the target cleaning duration, the controller will automatically generate a stop cleaning instruction and then send out a stop cleaning signal.

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

[0105] Among them, the target cleaning time can be set in a variety of ways. In some embodiments, the target cleaning time 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 method of presetting the default value as the target cleaning time does not require the user to set it manually, and the filter element cleaning function has a high degree of intelligence. In some embodiments, the user can also set the target cleaning time through the interactive module according to local water quality conditions, actual needs, and usage preferences. Exemplarily, the user can specify the target cleaning time in the issued filter element cleaning instruction. This method 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 time. Exemplarily, the controller can generate the target cleaning time based on information such as the filter element performance and the cleaning interval duration. By accurately controlling the cleaning time, the filter element can be effectively protected and its service life can be extended.

[0106] In some embodiments, the controller may also issue a stop cleaning instruction when detecting that the water volume inside the filter element is lower than a preset cleaning water volume threshold, thereby ensuring the cleaning effectiveness of the cleaning process and the safety of the filter element.

[0107] Step 404, obtaining the continuous operation time of the filter element cleaning device.

[0108] Step 406: When the continuous operation time is less than the target cleaning time, a prompt indicating that the cleaning time is insufficient is issued.

[0109] It is understandable that in actual applications, the cleaning process may be interrupted prematurely due to user intervention or other external factors. Therefore, after controlling the filter element cleaning device to stop, the controller will determine whether the continuous operation time of this cleaning has reached the target cleaning time. If the continuous operation time does not reach the target cleaning time, a prompt indicating that the cleaning time is insufficient will be issued.

[0110] The reminder that the cleaning time is insufficient can be presented to the user in a variety of ways, such as intuitively displayed on the display screen in the interactive module, through the flashing or color change of the indicator light, through the sound module to play a reminder sound, or send a notification message to the user's terminal device.

[0111] In this embodiment, by promptly issuing a reminder that the cleaning time is insufficient, the user can fully understand the completion status of the cleaning, which helps to improve the reliability of the electrical equipment.

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

[0113] Get the cleaning interval of the filter element;

[0114] Determine the target cleaning time based on the cleaning interval length.

[0115] The cleaning interval duration is the time from the moment the filter element cleaning device completes the previous cleaning to the current moment. The cleaning interval duration represents the length of time the filter element remains uncleaned between two consecutive cleanings, and can reflect the degree of accumulated contamination of the filter element. The current moment can be the moment when the filter element cleaning instruction is received, or the moment when the controller sends a filter element cleaning signal, that is, the moment when the cleaning operation officially starts.

[0116] There is no unique way to determine the target cleaning duration based on the cleaning interval duration. In some embodiments, determining the target cleaning duration based on the cleaning interval duration may include:

[0117] When the cleaning interval duration is greater than the filter element working duration threshold, the target cleaning duration is determined to be the first duration; when the cleaning interval duration is less than or equal to the filter element working duration threshold, the target cleaning duration is determined to be the second duration.

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

[0119] When the cleaning interval exceeds the filter element working time threshold, it can be considered that the filter element has not been cleaned for a long time and has accumulated a lot of pollutants. Therefore, a relatively long target cleaning time, i.e. the first time, will be determined to ensure that the pollutants on the filter element can be fully removed and its filtering performance can be restored.

[0120] If the cleaning interval is less than or equal to the filter element working time threshold, and the filter element has been cleaned for a short time, it is considered that its pollution level is relatively low. Therefore, a relatively short target cleaning time, i.e., the second time, is determined to avoid waste of resources and filter element loss caused by excessive cleaning.

[0121] In this embodiment, the target cleaning time is determined in combination with the actual cleaning interval of the filter element, which can more accurately match the actual cleaning requirements of the filter element, thereby helping to improve the cleaning efficiency and effectively extend the service life of the filter element.

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

[0123] The cleaning duration is matched according to the cleaning interval duration and the preset correspondence.

[0124] The preset corresponding relationship may be based on experimental data, experience summary or algorithm optimization, and may reflect the cleaning duration required for the filter element under different cleaning intervals. The preset corresponding relationship may be a relational expression or a grade classification table.

[0125] When the target cleaning duration needs to be determined, the controller first obtains the current cleaning interval duration, and then matches the corresponding cleaning duration according to the preset corresponding relationship, and uses it as the target cleaning duration. Since the corresponding relationship can better reflect the actual cleaning requirements of the filter element under different cleaning interval durations, the target cleaning duration obtained based on this matching can better match the actual cleaning requirements of the filter element, thereby improving the efficiency and accuracy of cleaning control.

[0126] Furthermore, when the controller controls the filter element cleaning device to stop working, if it detects that the continuous operation time is less than the target cleaning time, it will also record the time difference between the target cleaning time and the continuous operation time. In some embodiments, determining the target cleaning time according to the cleaning interval time may include:

[0127] The target cleaning time is determined based on the cleaning interval time and the time difference.

[0128] When determining the target cleaning duration according to the cleaning interval duration and the duration difference, the sum of the cleaning interval duration and the duration difference can be taken as a whole, and the method in the above embodiment is adopted to compare the sum with the filter element working duration threshold to 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 corresponding relationship.

[0129] Since the time difference reflects the extent to which the previous cleaning operation did not complete the scheduled task, that is, the extent to which the cleaning of the filter element did not achieve the target cleaning effect, a closed-loop detection of the filter element cleaning status is achieved. When the target cleaning time is subsequently determined, the target cleaning time is comprehensively determined based on the current cleaning interval time and the previously recorded time difference, which can ensure that this cleaning can make up for the previous cleaning deficiencies and improve the cleaning quality.

[0130] In order to better understand the above embodiment, the following is a detailed explanation in conjunction with an optional embodiment. Figure 5 , the filter element cleaning control methods include:

[0131] Receive the filter cleaning instruction issued by the user, turn on the pressure switch and water purification solenoid valve in the water outlet pipeline, and receive the feedback values ​​returned by the pressure switch and water purification solenoid valve (i.e., the water pressure parameters and water flow parameters in the water outlet pipeline).

[0132] According to the feedback values ​​returned by the pressure switch and the water purification solenoid valve, it is judged whether the internal water volume A of the filter element reaches the preset cleaning water volume threshold a. 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 solenoid valve is greater than the preset flow threshold q, it is judged that the internal water volume A of the current filter element is greater than the preset cleaning water volume threshold a, and the ultrasonic filter element cleaning device can be turned on.

[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 solenoid valve is not greater than the preset flow threshold q, it is judged that the current water volume A inside the filter element is less than the preset cleaning water volume threshold a, and the ultrasonic filter element cleaning device cannot be turned on. It can only be turned on after the conditions are met.

[0134] After detecting that the ultrasonic filter element cleaning device can be turned on, the target cleaning time of the ultrasonic filter element cleaning device (i.e., the working time of the adapted ultrasonic generator) is determined. Specifically, the cleaning interval time T of the filter element is first obtained, and the cleaning interval time T of the filter element is compared with the working time threshold t of the filter element. If the cleaning interval time T of the filter element is greater than the working time threshold t of the filter element, the working time Tc of the adapted ultrasonic generator is equal to the first time time1, otherwise the working time Tc of the adapted ultrasonic generator is equal to the second time time2.

[0135] After the working time Tc of the ultrasonic generator is determined, a filter element cleaning signal is immediately issued to trigger the ultrasonic filter element cleaning device to start working.

[0136] After receiving the stop cleaning instruction, a stop cleaning signal is sent to control the ultrasonic filter element cleaning device to stop working to end the cleaning operation. At the same time, the controller will also reset the cleaning interval time T of the filter element to zero to prepare for the next filter element cleaning operation.

[0137] The above filter element cleaning control method detects the current internal water volume of the filter element by combining the pressure switch and the water purification solenoid valve action. If it is detected that the internal water volume of the filter element meets the conditions for starting the ultrasonic filter element purification device, the ultrasonic filter element purification device is turned on. After the cleaning work is completed, the filter element cleaning interval time is automatically reset to zero; if the water volume requirement is not met, the ultrasonic filter element purification device is stopped to protect the filter element. At the same time, the cleaning interval time is combined to adapt different target cleaning times to ensure that the filter element is effectively cleaned and the filter element cleaning effect is improved.

[0138] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0139] Based on the same inventive concept, the embodiment of the present application also provides a filter element cleaning control device for implementing the filter element cleaning control method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of one or more filter element cleaning control devices provided below can refer to the limitations of the filter element cleaning control method above, and will not be repeated here.

[0140] In an exemplary embodiment, Figure 6 As shown, a filter element cleaning control device is provided, comprising: an instruction determination module 602, a water volume determination module 604 and a cleaning control module 606, wherein:

[0144] In one embodiment, the cleaning control module 606 is also used to issue a stop cleaning signal according to the stop cleaning instruction when a stop cleaning instruction is received; the stop cleaning signal is used to control the filter element cleaning device to stop working; obtain the continuous operation time of the filter element cleaning device; when the continuous operation time is less than the target cleaning time, issue a prompt that the cleaning time is insufficient.

[0145] In one embodiment, the cleaning control module 606 is further configured to generate a stop cleaning instruction when the filter element cleaning signal is sent and the target cleaning time is reached.

[0146] In one embodiment, the cleaning control module 606 is also used to obtain the cleaning interval duration of the filter element; the cleaning interval duration is the time from the moment when the filter element cleaning device completes the previous cleaning to the current moment; the target cleaning duration is determined based on the cleaning interval duration.

[0147] In one embodiment, the cleaning control module 606 is further configured to send a filter element cleaning signal when the amount of water inside the filter element is greater than or equal to a preset cleaning water amount threshold.

[0148] In one embodiment, the cleaning control module 606 is also used to issue a water-adding instruction when the internal water volume of the filter element is less than a preset cleaning water volume threshold, and the water-adding instruction is used to control the water inlet component of the electrical equipment to increase the raw water flow rate; the water inlet component is connected to the water inlet end of the filter element, and is used to control the water flow rate of raw water flowing into the filter element; when the internal water volume of the filter element is greater than or equal to the preset cleaning water volume threshold, a filter element cleaning signal is issued.

[0149] In one embodiment, the cleaning control module 606 is further used to determine the cleaning power of the filter element cleaning device according to the internal water volume of the filter element; and to issue a filter element cleaning signal based on the cleaning power.

[0150] In one embodiment, the cleaning control module 606 is also used to obtain the cleaning interval duration of the filter element, which is the time from the last time the filter element cleaning device completed cleaning to the current time; when the cleaning interval duration of the filter element reaches a preset time threshold, a filter element cleaning instruction is generated.

[0151] Each module in the above-mentioned filter element cleaning control device can be implemented in whole or in part by software, hardware, or a combination thereof. Each of the above-mentioned modules can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute the operations corresponding to each of the above modules.

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

[0153] The filter element 102 is used to receive raw water and filter the raw water to output filtered clean water for users to use. The filter element cleaning device 104 is used to clean the filter element 102. The filter element cleaning device 104 can be a device that uses an ultrasonic generator for cleaning (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 disposed inside the filter element 102 to improve the cleaning effect.

[0154] The electrical device further includes a water inlet assembly connected to the water inlet end of the filter element 102. The water inlet assembly is electrically connected to the controller 106. Under the control of the controller 106, the water inlet assembly adjusts the water flow rate 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.

[0155] In one embodiment, the electrical equipment further includes a water outlet pipeline, which is connected to the water outlet end of the filter element 102. A water purification solenoid valve electrically connected to the controller 106 is provided in the water outlet pipeline. After the water purification solenoid valve is turned on, the water filtered by the filter element 102 is output to the outside through the water outlet pipeline for users to take.

[0156] Since the opening of the water purification solenoid valve can reflect the water flow parameters in the water outlet pipeline, the controller 106 can obtain the feedback value of the water purification solenoid valve and determine the water flow parameters in the water outlet pipeline accordingly to monitor the water flow state in the water outlet pipeline. Monitoring the water flow state in the water outlet pipeline is conducive to the realization of functions such as filter element control and water quality monitoring.

[0157] A pressure switch electrically connected to the controller 106 is also provided in the water outlet pipeline. The pressure switch can detect the water pressure change in the water outlet pipeline and output the water pressure parameters in the water outlet pipeline to the controller 106, so that the controller 106 can monitor the water pressure parameters in the water outlet pipeline. When the water pressure in the water outlet pipeline is abnormal (such as 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.

[0158] In one embodiment, the water volume parameter of the filter element includes the water pressure parameter and the water flow parameter in the water outlet pipeline; the controller 106 is further used to determine the internal water volume of the filter element 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 volume of the filter element according to the water pressure parameter and the water flow parameter in the water outlet pipeline does not need to be limited, and those skilled in the art can make settings with reference to the commonly used techniques in the art.

[0159] Since the water outlet pipeline of the electrical equipment is usually equipped with a pressure switch and a water purification solenoid valve, in this embodiment, the feedback parameters of these two components are used to determine the internal water volume of the filter element 102. This method does not require the introduction of new detection components or structural improvements to the equipment, thereby avoiding cost increases.
