Description

Technical Field

[0001] This application relates to the field of water treatment equipment, and more particularly to sterilization control methods, apparatus, water treatment equipment and storage media. Background Technology

[0002] The sterilization technology in related water treatment equipment mainly relies on sodium hypochlorite generators, which use the electrolysis of brine during the regeneration process to produce chlorine-containing disinfectants. However, due to the complex internal structure of water treatment equipment, sodium hypochlorite cannot fully contact all areas, resulting in incomplete sterilization. Furthermore, excessively increasing the sodium hypochlorite concentration in these technologies does not completely solve the sterilization problem and can also negatively impact water quality, thus failing to meet the actual water usage needs of users. Summary of the Invention

[0003] This application provides a sterilization control method, apparatus, water treatment equipment, and storage medium, aiming to optimize the sterilization execution process of water treatment equipment, improve the sterilization efficiency of water treatment equipment, and thus enhance the user experience. The technical solution is as follows: In a first aspect, embodiments of this application provide a sterilization control method applied to a water treatment device, the water treatment device including a sodium hypochlorite generator and an ozone generator, comprising: Obtain the status and operating parameters of the water treatment equipment; If the operating parameters meet the preset first operating conditions, the water treatment equipment is controlled to operate in slow wash mode, and the ozone generator is controlled to enter the operating state to sterilize the water treatment equipment, and the water treatment equipment is controlled to switch from slow wash mode to forward and reverse wash mode. If the operating parameters meet the preset second operating conditions, the sodium hypochlorite generator is controlled to operate to sterilize the water treatment equipment. After the water treatment equipment enters the slow wash mode for a preset time, the water treatment equipment is controlled to switch from the slow wash mode to the forward and reverse wash mode.

[0004] Secondly, embodiments of this application provide a sterilization control device, including: The data acquisition unit is used to acquire the status and operating parameters of the water treatment equipment; The first execution unit is used to control the water treatment equipment to operate in slow washing mode and control the ozone generator to enter the operating state to sterilize the water treatment equipment if the state operating parameters meet the preset first operating conditions, and to control the water treatment equipment to switch from slow washing mode to forward and reverse washing mode. The second execution unit is used to control the sodium hypochlorite generator to sterilize the water treatment equipment if the state operation parameters meet the preset second operation conditions, and to control the water treatment equipment to switch from the slow wash mode to the forward and reverse wash mode after the water treatment equipment enters the slow wash mode for a preset time.

[0005] Thirdly, embodiments of this application provide a water treatment device, which includes: a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the sterilization control method as described above.

[0006] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program, which, when executed, implements the sterilization control method as described above.

[0007] In the above technical solution, the equipment status can be accurately determined by acquiring the operating parameters. When the first operating condition is met, combining the slow wash mode with ozone sterilization effectively removes impurities and thoroughly sterilizes the equipment. Switching to the forward and reverse wash mode ensures comprehensive cleaning. When the second operating condition is met, controlling the sodium hypochlorite generator to sterilize followed by a slow wash and then forward and reverse washes further ensures the sterilization effect by utilizing the strong oxidizing properties of sodium hypochlorite. At the same time, the slow wash helps to remove residual chemicals, preventing any impact on subsequent water use. This improves the overall water treatment quality and efficiency, and enhances the user's water safety. Attached Figure Description

Detailed Implementation

[0010] To make the features and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0011] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0012] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0013] To improve the safety of drinking water equipment, this application provides a sterilization control method, in which a water treatment device is the executing entity. The following is a detailed description; it should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments. Please refer to... Figure 1 , Figure 1 This is a schematic diagram illustrating a sterilization control method provided in an embodiment of this application. The specific process of the sterilization control method can be as follows: like Figure 1As shown, the water treatment equipment includes an ozone generator, a brine tank, a sodium hypochlorite generator, an ejector, and a resin tank. The sodium hypochlorite generator is used to electrolyze brine to produce hypochlorite ions. It is activated when brine is supplied to initially sterilize bacteria in the resin tank. Its operating time can be set according to the brine absorption duration. The ozone generator is used to generate ozone for comprehensive sterilization of the resin tank. It can be activated independently or in conjunction with the sodium hypochlorite generator. Its operating time is set according to different sterilization modes. The resin tank contains resin for removing water... The resin tank contains hardness ions (such as calcium and magnesium), but bacteria can easily grow in the resin tank after long-term use. Therefore, the resin tank is the main target for sterilization in this solution. Through the action of sodium hypochlorite and ozone, the inside of the resin tank can be kept clean to maintain good water softening performance. The jet injector provides negative pressure to the ozone generator, allowing air to be drawn into the ionization chamber inside the ozone generator. The salt tank is used to store brine to provide the chloride ion source required for the sodium hypochlorite generator to produce hypochlorite ions. During the regeneration and salt absorption process, the brine flows from the salt tank into the sodium hypochlorite generator for electrolysis.

[0014] In real-world scenarios, the sterilization mode to be entered by the water treatment equipment is determined based on multiple operating parameters within the equipment (such as remaining softened water volume, downtime, time since the last electrolysis start-up, and water volume in the resin tank). These sterilization modes can include powerful sterilization and conventional sterilization modes. This allows for dynamic adjustment of the working status of the sodium hypochlorite generator and ozone generator to provide more efficient sterilization effects to adapt to different usage needs and environmental conditions.

[0015] Specifically, when the water treatment equipment starts the sterilization program, it enters different sterilization modes based on the status operating parameters of the water treatment equipment (such as the remaining softened water volume, downtime, time since the last electrolysis start, and the water volume in the resin tank). The specific execution process of the sterilization program and the working time of each component can be set according to the actual use scenario, and no specific limitation is made here.

[0016] When the sodium hypochlorite generator is in operation, it absorbs the regenerated brine from the water treatment equipment. Then, under the action of an electric field, the chloride ions generated by the sodium hypochlorite generator migrate towards the anode, lose electrons to generate chlorine gas, and the hydrogen ions migrate towards the cathode, gain electrons to generate hydrogen gas. The hydrogen gas escapes and disrupts the ionization balance of the water near the cathode, generating hydroxide ions to form an alkaline environment. The chlorine gas reacts with the hydroxide ions to generate hypochlorite ions. Hypochlorite ions, with their strong oxidizing properties, perform preliminary sterilization on some bacteria and contaminants in the resin tank.

[0017] At the same time, the ejector activates to generate negative pressure, drawing air into the ozone generator. Inside the ozone generator, under the influence of a high-voltage electric field, the ionization chamber ionizes oxygen molecules in the air to form oxygen atoms. These oxygen atoms then combine with surrounding oxygen molecules to generate ozone molecules.

[0018] For example, in the powerful sterilization mode, if the remaining softened water volume of the water treatment equipment is detected to be greater than 60% of the preset cycle water production, and the downtime of the water treatment equipment is greater than 15 days, the control valve head of the water treatment equipment will rotate to execute the brine regeneration step. At the same time, the sodium hypochlorite generator will be turned on to control the sodium hypochlorite generator to enter the salt absorption step. At this time, the working time of the sodium hypochlorite generator is the same as the salt absorption time. The sodium hypochlorite solution generated by the sodium hypochlorite generator to absorb salt is used to perform preliminary sterilization on the water treatment equipment. After the sodium hypochlorite generator finishes running, the ozone generator and its control valve will be turned on immediately to allow the ozone generator to run for a preset time so that the ozone can perform deep sterilization on the resin tank. After sterilization is completed, the ozone generator and its control valve will be turned off, and the slow wash, backwash, and forward wash will continue to be completed before the wastewater is discharged through the wastewater discharge pipe.

[0019] For example, when the remaining softened water volume is less than 60% of the preset cycle water production, and the water treatment equipment has been shut down for more than 7 days but less than 15 days without monitoring flow or electrical signals, the water treatment equipment valve head rotates to execute the brine regeneration step. When entering the brine suction step, the sodium hypochlorite generator is turned on to generate sodium hypochlorite solution to sterilize the resin tank. After completing the slow wash, backwash, and forward wash process, the wastewater is discharged through the wastewater discharge pipe.

[0020] based on Figure 1 The scene diagram shown below will be combined with... Figures 2-8 This application provides a detailed description of a sterilization control method provided in its embodiments.

[0021] Based on the above, this application proposes a sterilization control method. Please refer to... Figure 2 , Figure 2 This is a schematic flowchart of a sterilization control method provided in an embodiment of this application. Figure 2 As shown, the method in this application embodiment may include the following steps S101-S103.

[0022] S101, Obtain the status and operating parameters of the water treatment equipment.

[0023] In this embodiment, the operating parameters may include at least the remaining softened water volume of the water treatment equipment, the downtime, the time since the last electrolysis start-up, and the water volume in the resin tank. The remaining softened water volume is the amount of water in the water treatment equipment that has been softened but not yet used. The downtime is the time the water treatment equipment has been shut down since the last operation ended. The time since the last electrolysis start-up refers to the interval between the end of the last electrolysis process and the current time. The water volume in the resin tank reflects the current state of the resin and the processing capacity of the equipment.

[0024] Specifically, the water treatment equipment uses built-in sensors and metering devices to monitor and record its operational data in real time, including but not limited to the remaining softened water volume, downtime, time since the last electrolysis start-up, and the water volume in the resin tank. This data is transmitted to the control unit or cloud server via a built-in communication module. Subsequently, the control unit or cloud server integrates and analyzes this data to generate status operating parameters.

[0025] S102, if the operating parameters meet the preset first operating conditions, control the water treatment equipment to operate in slow wash mode, and control the ozone generator to enter the operating state to sterilize the water treatment equipment, and control the water treatment equipment to switch from slow wash mode to forward and reverse wash mode.

[0026] In this embodiment, the first operating conditions can be set according to actual usage requirements. The remaining soft water volume and downtime of the water treatment equipment are used as the first operating conditions for the following description.

[0027] Specifically, the remaining soft water volume and downtime of the water treatment equipment are extracted from the status operation parameters. If the remaining soft water volume is detected to be greater than the preset periodic soft water volume and the downtime of the water treatment equipment is detected to be greater than the preset first downtime, the water treatment equipment is controlled to enter the first strong sterilization mode.

[0028] In the first powerful sterilization mode, the water treatment equipment is switched to a slow rinse mode. In this mode, the equipment cleans its interior with a lower flow rate and a specific cleaning procedure. Simultaneously, the ozone generator is activated and begins producing ozone gas to sterilize the equipment. After the slow rinse and sterilization process is complete, the equipment switches from slow rinse mode to a reverse rinse mode after a preset time. In this reverse rinse mode, the alternating forward and reverse water flow effectively removes any remaining impurities and particulate matter, completing the entire cleaning and sterilization process and ensuring efficient operation and continuous water quality optimization.

[0029] Under the first operating conditions, if the remaining soft water volume is detected to be greater than the preset cycle soft water volume, then when the shutdown duration is greater than the preset first shutdown duration and greater than the second shutdown duration, the water treatment equipment is controlled to enter the first normal sterilization mode.

[0030] In the first conventional sterilization mode, the water treatment equipment is controlled to enter a slow rinse mode to clean its internal components at a low flow rate and according to a preset cleaning program. Simultaneously, the ozone generator is controlled to run for a preset time and then stop. The water treatment equipment then continues to run in slow rinse mode for a preset time before entering a forward and reverse rinse mode. Once the forward and reverse rinse mode is completed, the wastewater in the effluent equipment is discharged. In this process, the ozone generator's operating time must be less than the time required when the remaining soft water volume is greater than the preset cycle soft water volume and the shutdown time is greater than the preset first shutdown time.

[0031] S103, if the operating parameters meet the preset second operating conditions, control the sodium hypochlorite generator to operate to sterilize the water treatment equipment, control the water treatment equipment to enter the slow wash mode for a preset time, and then control the water treatment equipment to switch from the slow wash mode to the forward and reverse wash mode.

[0032] In this embodiment, the second operating conditions can be set according to actual usage requirements. The remaining soft water volume and downtime of the water treatment equipment are used as the second operating conditions for the following description.

[0033] Specifically, if the remaining soft water volume is less than the preset cycle soft water volume and the shutdown duration is longer than the first shutdown duration, the water treatment equipment will be controlled to enter the second powerful sterilization mode.

[0034] In the second powerful sterilization mode, the water treatment equipment activates the sodium chlorate generator to produce sodium hypochlorite solution. If the brine capacity in the water treatment equipment is insufficient during this process, a brine regeneration step is executed to provide sufficient brine to the sodium chlorate generator. After the sodium chlorate generator has finished operating, the ozone generator is controlled to run for a preset time to further sterilize the water treatment equipment. After the ozone generator completes sterilization, it is turned off, and the water treatment equipment enters a slow rinse mode. After the water treatment equipment has run in slow rinse mode for a preset time, it switches to a forward and reverse rinse mode. After the forward and reverse rinse modes are completed, the water treatment equipment stops operating, thus completing the entire sterilization and cleaning process to ensure the efficient and safe operation of the water treatment equipment.

[0035] Under the first operating conditions, if the remaining soft water volume is less than the preset periodic soft water volume and the shutdown duration is less than the first shutdown duration and the second shutdown duration, the water treatment equipment is controlled to enter the second conventional sterilization mode.

[0036] In the second conventional sterilization mode, the water treatment equipment first starts the sodium hypochlorite generator, which absorbs brine to produce a sodium hypochlorite solution for sterilizing the resin tank. After confirming the sodium hypochlorite generator has finished operating, the water treatment equipment switches to a slow rinse mode. In slow rinse mode, the equipment runs continuously for a preset time to ensure thorough cleaning. After the slow rinse mode ends, the equipment switches to a forward and reverse rinse mode, using alternating forward and reverse water flow to further remove any remaining impurities. Finally, after the forward and reverse rinse modes are completed, the wastewater is discharged and the water treatment equipment stops operating, completing the entire sterilization and cleaning process.

[0037] As shown above, by acquiring the operating parameters, the equipment status can be accurately determined. When the first operating condition is met, combining the slow wash mode with ozone sterilization effectively removes impurities and thoroughly sterilizes the equipment. Switching to the forward and reverse wash mode ensures comprehensive cleaning. When the second operating condition is met, controlling the sodium hypochlorite generator to sterilize followed by a slow wash and then forward and reverse washes further ensures the sterilization effect by utilizing the strong oxidizing properties of sodium hypochlorite. This improves the overall water treatment quality and efficiency, and enhances the user's water safety.

[0038] Because water treatment equipment may be left unused for extended periods in real-world applications, the internal environment of the equipment can become relatively poor during these times. Therefore, the equipment needs to automatically clean and sterilize itself based on the specific circumstances. Please refer to [link / reference needed]. Figure 3 , Figure 3 This is a schematic flowchart of a sterilization control method provided in an embodiment of this application. Figure 3 As shown, the method in this application embodiment may include the following steps S201-S206.

[0039] S201, extract the remaining soft water volume and downtime of the water treatment equipment from the status operation parameters.

[0040] Specifically, the system obtains the operating status parameters of the water treatment equipment by accessing local storage units or cloud servers, and extracts data items related to the remaining soft water volume from these parameters. This data can be directly represented as a numerical value of the remaining soft water volume, or it can be obtained indirectly through a series of calculations (such as calculations based on the total influent volume, the volume of water already treated, and other relevant data). Similarly, the system obtains the downtime data of the water treatment equipment from the operating status parameters. The downtime can be calculated based on the difference between the time the water treatment equipment stopped operating and the time of the last stop, or it can be accumulated and recorded from the moment the equipment stopped operating using a dedicated timing device.

[0041] For example, the remaining soft water volume extracted from the status operation parameters is 500 liters, and the downtime is 5 days.

[0042] S202, if the remaining soft water volume is greater than the preset cycle soft water volume, the water treatment equipment will be controlled to enter the slow wash mode and the ozone generator will be controlled to enter the running state when the shutdown time is longer than the preset first shutdown time.

[0043] Specifically, the extracted remaining soft water volume data is compared with the preset periodic soft water volume data. The preset periodic soft water volume is a standard value pre-set based on factors such as the design specifications, processing capacity, and normal operating cycle of the water treatment equipment. It is used to measure whether the current remaining soft water volume of the equipment is at a normal level or requires special treatment, and no specific limitation is made here.

[0044] If the comparison result shows that the remaining soft water volume is greater than the preset cycle soft water volume and the shutdown time is greater than the preset first shutdown time, a command is sent to the control unit of the water treatment equipment to put it into slow wash mode. In slow wash mode, parameters such as water flow rate and rinsing method inside the equipment are adjusted according to the preset slow wash program, such as reducing water flow rate and extending rinsing time, to achieve better cleaning effect.

[0045] At the same time, a start signal is sent to the ozone generator to trigger it to start working, preparing to use the strong oxidizing properties of ozone to sterilize the resin tank of the water treatment equipment.

[0046] S203, if the working time of the ozone generator is equal to the first working time, then control the ozone generator to stop operating.

[0047] Specifically, a timer corresponding to the ozone generator is activated to continuously monitor its operating time. When the ozone generator's operating time reaches a preset first operating time (which is an optimal operating time determined based on factors such as the ozone generator's performance, the effective dosage required for sterilization, and the internal space of the equipment, and is not specifically limited here), a stop-operation command is sent to the ozone generator to stop producing ozone and end the current sterilization process, thus preventing potential damage to the equipment or waste of resources due to excessive ozone production.

[0048] For example, the ozone generator starts working, and the timer starts running. When the ozone generator has run for 60 minutes (reaching the first working duration), the ozone generator is controlled to stop running.

[0049] S204: After the water treatment equipment has been running in slow wash mode for the second working time, control the water treatment equipment to enter forward and reverse wash mode. After the forward and reverse wash mode is completed, control the water treatment equipment to stop running.

[0050] Specifically, after the ozone generator is turned off, the control system enters a slow wash mode and starts a timer associated with this mode to calculate its running time. When the accumulated running time of the slow wash mode reaches a preset second working duration, a command is sent to the control unit of the water treatment equipment to switch from slow wash mode to a reverse wash mode. In the reverse wash mode, the water treatment equipment changes the water flow direction, first performing a reverse rinse to flush deep-seated dirt and residues to the outlet, and then performing a forward rinse to thoroughly remove impurities. The second working duration is a suitable length determined based on research into the cleaning effect on dirt and impurities inside the equipment and the requirements for seamless transitions between subsequent reverse wash modes; it is not specifically limited here. S205, if the remaining soft water volume is greater than the cycle soft water volume, the water treatment equipment will be controlled to enter the slow wash mode when the downtime is less than the first downtime but greater than the second downtime, and the ozone generator will be controlled to stop running after the third working time, where the second downtime is less than the first downtime.

[0051] Specifically, following the same execution steps as in S202 above, the extracted remaining soft water volume is compared again with the preset cycle soft water volume. If it is confirmed that the remaining soft water volume is greater than the cycle soft water volume and the shutdown time is less than the first shutdown time but greater than the second shutdown time, the first normal sterilization mode is entered, that is, a control command is sent to the water treatment equipment to enter the slow wash mode. At the same time, a start command is sent to the ozone generator to start it running and start the running timer that matches the ozone generator.

[0052] When the ozone generator reaches the preset third working time, a stop command is sent to the ozone generator to stop its operation and end the ozone sterilization process. The third working time is a relatively short effective sterilization time determined based on the current downtime range and the equipment sterilization requirements, and is not specifically limited here.

[0053] S206, after the water treatment equipment runs in slow wash mode for the fourth preset time, it enters forward and reverse wash mode. After the forward and reverse wash mode is completed, the water treatment equipment stops running.

[0054] Specifically, after the ozone generator stops operating, a timer associated with the slow wash mode is started to calculate the running time of the water treatment equipment in the current slow wash mode. When the accumulated running time in the slow wash mode reaches the fourth preset duration, the water treatment equipment is controlled to switch from the slow wash mode to the forward and reverse wash mode. The fourth preset duration is a time length determined based on a comprehensive consideration of the equipment cleaning effect and the preparation for the subsequent forward and reverse wash modes, and is not specifically limited here.

[0055] After the forward and reverse washing modes have been completed, a stop operation command is sent to the water treatment equipment to end the entire operation process of the water treatment equipment. At this time, the water treatment equipment is in standby mode.

[0056] For example, the water treatment equipment has a remaining soft water volume of 120 cubic meters, but the downtime is 20 days. In this case, 120 cubic meters is greater than 100 cubic meters (remaining soft water volume is greater than the cycle soft water volume), and 20 days is less than 30 days (downtime is less than the first downtime) but greater than 15 days (downtime is greater than the second downtime). Therefore, the water treatment equipment is controlled to enter a slow wash mode, and the ozone generator is started and runs for 30 minutes (the third working time) before stopping. After the ozone generator stops, the water treatment equipment runs in slow wash mode for 35 minutes (the fourth preset time), then enters a forward and reverse wash mode, and stops after both forward and reverse washes are completed.

[0057] Please refer to the following: Figure 4 , Figure 4 This is a schematic diagram illustrating a sterilization control method provided in an embodiment of this application. For example... Figure 4 As shown: When the remaining soft water volume is greater than the preset cycle soft water volume, it is determined whether the shutdown duration is greater than the first shutdown duration. If the shutdown duration is greater than the first shutdown duration, the first powerful sterilization mode will be executed, i.e., the execution process of S202-S204 above will be executed; if the shutdown duration is not greater than the first shutdown duration, it is further determined whether the shutdown duration is greater than the second shutdown duration. If the shutdown duration is greater than the second shutdown duration, the first normal sterilization mode will be executed, i.e., the execution process of S205-S206 above will be executed.

[0058] As shown above, by selecting whether to enter the slow wash mode and controlling the ozone generator's operating time based on the remaining soft water volume and the duration of downtime, it is possible to effectively prevent bacterial growth inside the equipment, ensuring water cleanliness and safety. Furthermore, it avoids resource waste and equipment damage caused by excessive operation of the ozone generator and other equipment. Simultaneously, the reasonable switching between slow wash and forward / reverse wash modes ensures thorough cleaning of the equipment's interior, maintaining optimal operating conditions and extending its lifespan.

[0059] To further improve the cleaning efficiency of water treatment equipment, please refer to [link / reference needed]. Figure 5 , Figure 5 This is a schematic flowchart of a sterilization control method provided in an embodiment of this application. Figure 5 As shown, the method in this application embodiment may include the following steps S301-S309.

[0060] S301, extract the remaining soft water volume and downtime of the water treatment equipment from the status operation parameters.

[0061] For details on the specific execution process of S301, please refer to S201 above, which will not be repeated here.

[0062] S302, if the remaining soft water volume is less than the preset cycle soft water volume, the sodium hypochlorite generator will be controlled to enter the running state when the shutdown duration is longer than the first shutdown duration.

[0063] Specifically, if the remaining soft water volume is less than the preset cycle soft water volume, the shutdown duration is then compared with the first shutdown duration. If the shutdown duration is longer than the first shutdown duration, the water treatment equipment is controlled to enter the second powerful sterilization mode. At this time, the sodium hypochlorite generator is controlled to enter the running state, ready to carry out sterilization operations.

[0064] S303 uses a sodium hypochlorite generator to produce a sodium hypochlorite solution for sterilizing water treatment equipment.

[0065] Specifically, in the sodium hypochlorite generator, when the absorbed brine is applied by an electric field, chloride ions in the brine migrate towards the anode, where they lose electrons and are oxidized to produce chlorine gas. Simultaneously, hydrogen ions from water dissociation gain electrons at the cathode and are reduced to hydrogen gas, which escapes from the cathode. The continuous gain of electrons by hydrogen ions near the cathode to produce hydrogen gas disrupts the ionization balance of water, leading to the generation of more hydroxide ions and creating an alkaline environment. The generated chlorine gas reacts with hydroxide ions to form hypochlorite ions, which then combine with sodium ions to form a sodium hypochlorite solution.

[0066] The generated sodium hypochlorite solution is transported through pipelines to the resin tank and other areas of the water treatment equipment that require sterilization. The strong oxidizing properties of sodium hypochlorite are used to oxidize and kill the bacteria, thereby achieving the sterilization effect on the water treatment equipment.

[0067] S304 If the sodium chlorate generator is detected to have finished running, the ozone generator will be shut down after running for the fifth preset time, and the water treatment equipment will be controlled to enter the slow wash mode.

[0068] Specifically, the operation status monitoring program for the sodium hypochlorite generator is initiated. This program monitors parameters such as current, voltage, and temperature, as well as the progress of internal chemical reactions (indirect indicators such as brine consumption rate and chlorine production), to determine whether the sodium hypochlorite generator has completed its operation. Once the sodium hypochlorite generator is detected to have completed its operation, the ozone generator is controlled to operate for the fifth preset time. Simultaneously, a command is sent to the valve control module of the water treatment equipment to adjust the valve status, putting the water treatment equipment into a slow-wash mode in preparation for subsequent cleaning operations.

[0069] S305: After the water treatment equipment has been running in slow wash mode for six preset durations, control the water treatment equipment to enter forward and reverse wash mode. After the forward and reverse wash mode is completed, control the water treatment equipment to stop running.

[0070] Specifically, the water treatment equipment is controlled to enter slow wash mode, and a timer associated with the slow wash mode is started to record the running time of the slow wash mode. During the slow wash process, the water inside the water treatment equipment circulates in components such as the resin tank at a low speed and in a specific direction. The water flow carries away some residual disinfectant and other impurities, but does not cause excessive impact on the equipment.

[0071] When the slow wash time recorded by the timer reaches the sixth preset duration, a command is sent to the valve control module of the water treatment equipment to switch the valve status, so that the equipment can switch from slow wash mode to forward and reverse wash mode.

[0072] In both forward and reverse washing modes, the equipment first performs a reverse flush, where the water flow direction is opposite to that during normal operation, flushing impurities deep inside the resin tank and other components towards the outlet. Then, a forward flush is performed to thoroughly remove the impurities flushed out during the reverse flush, along with other residual impurities from the equipment.

[0073] Further monitoring of parameters such as water quality, pressure, and flow rate of the wastewater is used to determine whether the forward and reverse washing modes have been completed. When these parameters meet preset standards (such as clear wastewater, stable pressure, and normal flow rate), a stop operation command is sent to the control unit of the water treatment equipment, causing the equipment to stop working and completing the sterilization process.

[0074] S306 If the remaining soft water volume is less than the preset cycle soft water volume, the sodium hypochlorite generator will be controlled to enter the operating state when the shutdown duration is less than the first shutdown duration and the second shutdown duration.

[0075] Specifically, if the remaining soft water volume is less than the preset cycle soft water volume and the shutdown duration is less than the first shutdown duration and the second shutdown duration, the water treatment equipment will be controlled to enter the second normal sterilization mode. At this time, the sodium hypochlorite generator will be controlled to enter the running state to prepare for sterilization operation. The first shutdown duration and the second shutdown duration can be set according to the actual scenario and are not specifically limited here.

[0076] S307 uses a sodium hypochlorite generator to produce a sodium hypochlorite solution for sterilizing water treatment equipment.

[0077] For details on the specific execution process of S307, please refer to S303 above, which will not be repeated here.

[0078] S308: If the sodium chlorate generator is detected to have finished running, the water treatment equipment will be controlled to enter the slow wash mode.

[0079] Specifically, a monitoring program for the sodium hypochlorite generator is initiated. This program monitors parameters such as current, voltage, and temperature, as well as the progress of internal chemical reactions (indirect indicators such as brine consumption rate and chlorine production), to determine whether the sodium hypochlorite generator has completed its operation. Once the generator is detected to have finished operating, a command is sent to the valve control module of the water treatment equipment to put the equipment into slow-wash mode, preparing it for subsequent cleaning operations.

[0080] S309: After the water treatment equipment has been running in slow wash mode for seven preset times, control the water treatment equipment to enter forward and reverse wash mode. After the forward and reverse wash mode is completed, control the water treatment equipment to stop running.

[0081] Specifically, after running in slow wash mode for the seventh preset time, the water treatment equipment switches to reverse and forward wash mode to remove residual impurities from the equipment. Once the backwash mode is detected as completed, a stop command is sent to the water treatment equipment to stop it and end the current treatment process.

[0082] For example, the seventh preset duration is 30 minutes. After the water treatment equipment is detected to be running in slow wash mode for 30 minutes, the water treatment equipment is controlled to enter reverse and forward flushing and work for 15 minutes before the wastewater is discharged and the water treatment equipment is controlled to stop running.

[0083] Please refer to the following: Figure 6 , Figure 6 This is a schematic diagram illustrating a sterilization control method provided in an embodiment of this application. For example... Figure 6 As shown: When the remaining soft water volume is less than the preset cycle soft water volume, it is determined whether the shutdown duration is greater than the first shutdown duration. If the shutdown duration is less than the first shutdown duration, the execution process of S302-S305 above is executed. If it is less than the first shutdown duration, the execution process of S306-S309 above is executed. This will not be elaborated further here.

[0084] As shown above, by selecting whether to enter the slow wash mode and controlling the ozone generator's operating time based on the remaining soft water volume and the duration of downtime, it is possible to effectively prevent bacterial growth inside the equipment, ensuring water cleanliness and safety. Furthermore, it avoids resource waste and equipment damage caused by excessive operation of the ozone generator and other equipment. Simultaneously, the reasonable switching between slow wash and forward / reverse wash modes ensures thorough cleaning of the equipment's interior, maintaining optimal operating conditions and extending its lifespan.

[0085] Traditional water softener sterilization methods may not be thorough, for example, relying on a single sterilization method or failing to ensure the sterilizing agent fully contacts all parts of the resin tank. Please see [link / reference]. Figure 7 , Figure 7 This is a schematic flowchart of a sterilization control method provided in an embodiment of this application. Figure 7 As shown, the method in this application embodiment may include the following steps S401-S402.

[0086] S401, extract a preset amount of dissolved salt from the salt tank, and mix the dissolved salt with a preset amount of water in the water treatment equipment to generate brine.

[0087] Specifically, information about the dissolved salt in the salt tank is obtained, such as the salt quantity and distribution. Then, according to the preset quantity requirement, the corresponding extraction device is activated. This extraction device can be a suction pump with metering function or a mechanical salt extraction device, capable of accurately removing the specified quantity of dissolved salt from the salt tank. During the extraction process, factors such as salt flowability and clumping are considered. If clumping occurs, it needs to be broken up or dispersed first to ensure that the preset quantity of dissolved salt can be successfully extracted.

[0088] At the same time, by adjusting the pipeline control valve to obtain a preset capacity of water, the extracted dissolved salt and the obtained water are introduced into a special fusion container or area to allow the dissolved salt to be fully mixed and dissolved in the water to form a uniform salt solution.

[0089] S402 is based on a sodium hypochlorite generator absorbing brine to generate a sodium hypochlorite solution, and using the sodium hypochlorite solution to sterilize the resin tank.

[0090] Specifically, while brine is being generated, the sodium hypochlorite generator is being controlled to operate and the brine is being delivered to it. The sodium hypochlorite generator contains a specific electrolysis device and a reaction chamber. After the brine enters the reaction chamber, a chemical reaction begins under the action of the electrolysis device.

[0091] During electrolysis, anions migrate towards the anode, and cations migrate towards the cathode. Near the anode, chloride ions lose electrons and are oxidized to produce chlorine gas; near the cathode, hydrogen ions gain electrons and are reduced to produce hydrogen gas. The generation of hydrogen gas at the cathode disrupts the ionization equilibrium of water, producing more hydroxide ions (OH-). - An alkaline environment is formed, and chlorine gas generates hypochlorite ions in the alkaline environment. The hypochlorite ions combine with sodium ions to form sodium hypochlorite solution.

[0092] The generated sodium hypochlorite solution is introduced into the resin tank through a pipeline. The resin tank is filled with resin used for water softening. Over long-term use, this resin is prone to bacterial and microbial growth, affecting the softening effect and water quality safety. After entering the resin tank, the sodium hypochlorite solution utilizes its strong oxidizing properties to kill and disinfect bacteria and microorganisms on the resin surface and inside the tank.

[0093] As shown above, by executing the extraction of dissolved salts, the preparation of brine, the generation of sodium hypochlorite solution, and the sterilization of the resin tank, precise control can be achieved according to preset programs and parameters. This helps to improve the intelligence level of the water softener, reduce manual intervention, ensure the consistency and effectiveness of each sterilization process, and improve the overall operating efficiency and stability of the equipment.

[0094] Traditional water treatment equipment cannot control the sterilization process based on users' actual water usage habits and equipment usage conditions, thus affecting sterilization efficiency. Please see... Figure 8 , Figure 8 This is a schematic flowchart of a sterilization control method provided in an embodiment of this application. Figure 8 As shown, the method in this application embodiment may include the following steps S501-S503.

[0095] S501, obtain the status and operating parameters of the water treatment equipment.

[0096] For the specific execution process of S501, please refer to S101 above, which will not be repeated here.

[0097] S502, obtain user water usage data for water treatment equipment, including water usage duration and water usage stoppage duration.

[0098] In this embodiment, the water treatment equipment communicates with devices such as flow sensors and smart meters installed in the water inlet pipe of the water treatment equipment or at the user's water terminal. These devices can monitor and record the water flow in real time. They may also work in conjunction with a built-in timer to accurately record the duration of water use and the duration of water cessation.

[0099] Specifically, when a user starts using water, the flow sensor detects the water flow signal and transmits it to the water timer of the water treatment equipment. The water timer then starts recording the water usage time, continuously accumulating the time from the moment the water begins to flow until the water stops. The accumulated time at this point is the duration of the water usage.

[0100] After a user stops using water, a water usage timer records the duration of the stoppage. The timer starts counting from the moment water usage stops and continues until the next water usage session begins or a preset statistical period ends. If the user resumes using water within the statistical period, the timer pauses, and the duration of the stoppage is recorded. At the end of the statistical period (e.g., one day, one week), the accumulated stoppage time data is compiled and stored for subsequent analysis.

[0101] S503 determines the operating time of the ozone generator and sodium chlorate generator based on water usage data.

[0102] Specifically, the obtained data on water usage duration and water usage cessation duration are substituted into the correlation model for calculation. This correlation model can calculate the appropriate working duration of the ozone generator and sodium chlorate generator under the current conditions according to the input data and the preset algorithm and logic rules. The correlation model may include linear regression model, decision tree model and neural network model, without specific limitations here.

[0103] Based on the calculation results, the final operating time of the ozone generator and sodium chlorate generator is determined. The calculation results are then appropriately adjusted and optimized, taking into account the current state of the water treatment equipment, remaining resources (such as the amount of salt in the brine tank and the energy consumption of the ozone generator), and other external factors (such as ambient temperature and initial water quality). For example, if the salt level in the brine tank is low, the operating time of the sodium chlorate generator may be shortened to avoid excessive salt consumption; if the ambient temperature is high and bacterial growth is accelerated, the operating time of the ozone generator may be extended to ensure sterilization effectiveness. The final determined operating time will be sent as a control command to the corresponding generator, causing it to operate according to the set duration, achieving precise sterilization treatment of the water treatment equipment.

[0104] As shown above, acquiring user data on water usage duration and shutdown times for water treatment equipment provides crucial information for subsequent precise control. Determining the operating hours of the ozone generator and sodium chlorate generator based on this data solves the problem of insufficient targeting in traditional water treatment equipment's sterilization control. It avoids resource waste and equipment damage caused by over-sterilization, while ensuring sufficient sterilization is provided when necessary, based on users' actual water usage habits and equipment conditions. This helps improve sterilization efficiency, ensures consistently good water quality, extends equipment lifespan, reduces operating costs, and enhances the user experience.

[0108] In some embodiments, the first execution unit 602 further includes a third determination unit and a second control unit.

[0109] The third determination unit is used to control the water treatment equipment to enter the slow wash mode when the remaining soft water volume is greater than the cycle soft water volume, and when the shutdown time is less than the first shutdown time but greater than the second shutdown time. It also controls the ozone generator to stop running after the third working time, where the second shutdown time is less than the first shutdown time. The second control unit is used to control the water treatment equipment to run in slow wash mode for a fourth preset time and then enter forward and reverse wash mode. After the forward and reverse wash mode is completed, the water treatment equipment is controlled to stop running.

[0110] In some embodiments, the first execution unit 602 further includes a fourth determination unit, a third control unit, a fifth determination unit, and a fourth control unit.

[0111] The fourth determination unit is used to control the sodium hypochlorite generator to enter the running state if the remaining soft water volume is less than the preset cycle soft water volume and the shutdown time is longer than the first shutdown time. The third control unit is used to generate sodium hypochlorite solution based on the sodium hypochlorite generator to sterilize the water treatment equipment; The fifth determination unit is used to control the ozone generator to run for a fifth preset time and then shut it off if the sodium chlorate generator is detected to have finished running, and to control the water treatment equipment to enter the slow wash mode.

[0114] In some embodiments, the second execution unit 603 further includes a brine generation unit and a solution generation unit.

[0115] The brine generation unit is used to extract a preset amount of dissolved salt from the salt tank and mix the dissolved salt with a preset amount of water in the water treatment equipment to generate brine. The solution generation unit is used to absorb brine from the sodium hypochlorite generator to generate a sodium hypochlorite solution, and to sterilize the resin tank based on the sodium hypochlorite solution. The running time of the sodium hypochlorite generator is the same as the brine absorption time.

[0116] In some embodiments, the second execution unit 603 further includes a water usage data acquisition unit and a working time generation unit.

[0117] The water usage data acquisition unit is used to acquire water usage data of users for water treatment equipment.

[0118] In this embodiment, the equipment status can be accurately determined by acquiring the operating parameters. When the first operating condition is met, combining the slow wash mode with ozone sterilization effectively removes impurities and thoroughly sterilizes the equipment. Switching to the forward and reverse wash mode ensures comprehensive cleaning. When the second operating condition is met, controlling the sodium hypochlorite generator to sterilize followed by a slow wash and then forward and reverse washes further ensures the sterilization effect by utilizing the strong oxidizing properties of sodium hypochlorite. At the same time, the slow wash helps to remove residual chemicals, preventing any impact on subsequent water use. This improves the overall water treatment quality and efficiency, and enhances the user's water safety.
