[0001] The present application relates to the field of water treatment equipment, and in particular to a sterilization control method, device, water treatment equipment and storage medium. Background Art

[0002] The sterilization technology of related water treatment equipment mainly relies on sodium hypochlorite generators, which use the electrolysis of salt water during the regeneration process to produce chlorine-containing disinfectants. However, due to the complex internal structure of the water treatment equipment, it is difficult for sodium hypochlorite to fully contact all areas, resulting in incomplete sterilization. In addition, excessively increasing the concentration of sodium hypochlorite in related technologies cannot completely solve the sterilization problem, and will also have a certain impact on water quality, thus failing to meet the actual water needs of users. Summary of the invention

[0003] This application provides a sterilization control method, device, water treatment equipment and storage medium, which aims to optimize the sterilization execution process of the water treatment equipment, improve the sterilization efficiency of the water treatment equipment and thus enhance the user experience. The technical solution is as follows:

[0004] In a first aspect, an embodiment of the present application provides a sterilization control method, which is applied to a water treatment device, wherein the water treatment device includes a sodium hypochlorite generator and an ozone generator, including:

[0006] If the state operation parameter meets the preset first operation condition, the water treatment equipment is controlled to operate in the slow wash mode, and the ozone generator is controlled to enter the operation state to sterilize the water treatment equipment, and the water treatment equipment is controlled to switch from the slow wash mode to the forward and reverse wash mode;

[0007] If the status 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 is controlled to enter the slow wash mode and operate for a preset period of time, the water treatment equipment is controlled to switch from the slow wash mode to the forward and backwash mode.

[0008] In a second aspect, an embodiment of the present application provides a sterilization control device, comprising:

[0010] A first execution unit is used to control the water treatment equipment to operate in a slow wash mode if the state operation parameter meets a preset first operation condition, and control the ozone generator to enter an operation state to sterilize the water treatment equipment, and control the water treatment equipment to switch from the slow wash mode to the forward and reverse wash mode;

[0011] The second execution unit is used to control the operation of the sodium hypochlorite generator to sterilize the water treatment equipment if the state operation parameter meets the preset second operation condition, and control the water treatment equipment to enter the slow wash mode and run for a preset time, and then control the water treatment equipment to switch from the slow wash mode to the forward and backwash mode.

[0012] In a third aspect, an embodiment of the present application provides a water treatment device, which includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the computer program is executed by the processor, any of the above sterilization control methods is implemented.

[0026] In order to make the features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0027] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0028] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying 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 the features.

[0029] In order to improve the safety of drinking water equipment, the present application provides a sterilization control method, and the execution subject of the sterilization control method is a water treatment device. The following is a detailed description. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Figure 1 , Figure 1 Schematic diagram of a sterilization control method provided in an embodiment of the present application. The specific process of the sterilization control method can be as follows:

[0030] like Figure 1 As shown, the water treatment equipment includes an ozone generator, a salt box, a sodium hypochlorite generator, an ejector and a resin tank, wherein the sodium hypochlorite generator is used to electrolyze salt water to produce hypochlorite, and is started when salt water is supplied to perform preliminary sterilization on bacteria in the resin tank, and its working time can be set according to the salt absorption time, etc.; the ozone generator is used to generate ozone to sterilize the resin tank comprehensively, and can be started alone or in a mode coordinated with the sodium hypochlorite generator, and the working time is set according to different sterilization modes; the resin tank is filled with resin for removing water The hardness ions (such as calcium and magnesium) in the resin tank are easily bred with bacteria after long-term use. Therefore, the resin tank is the main object of sterilization in this scheme. Through the action of sodium hypochlorite and ozone, the inside of the resin tank can be kept clean to maintain good softening water performance; the ejector provides negative pressure for the ozone generator, so that air can be sucked into the ionization chamber inside the ozone generator; the salt box is used to store brine to provide the sodium hypochlorite generator with the source of chloride ions required to produce hypochlorite. During the regeneration salt absorption process, the brine flows from the salt box into the sodium hypochlorite generator for electrolysis reaction.

[0031] In actual scenarios, the sterilization mode that the water treatment equipment is to enter is determined based on multiple operating parameters of the internal status of the water treatment equipment (such as the remaining softened water volume, downtime, time since the last electrolysis start, and the amount of water in the resin tank). The sterilization mode may include a strong sterilization mode and a conventional sterilization mode, and then dynamically adjust the working status of the sodium hypochlorite generator and the ozone generator to provide a more efficient sterilization effect to adapt to different usage requirements and environmental conditions.

[0032] Specifically, when the water treatment equipment starts the sterilization program, it enters different sterilization modes according to 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 amount of water 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 usage scenario, and no specific limitations are made here.

[0033] When the sodium hypochlorite generator is in operation, it absorbs the regenerated brine from the water treatment equipment. Then, under the action of the electric field, the chloride ions produced by the sodium hypochlorite generator migrate to the anode and lose electrons to generate chlorine gas, and the hydrogen ions migrate to the cathode to gain electrons to generate hydrogen gas. The hydrogen gas escapes and destroys the ionization balance of the water near the cathode to generate hydroxide to form an alkaline environment. Chlorine gas reacts with hydroxide to generate hypochlorite. Hypochlorite uses its strong oxidizing property to initially sterilize some bacteria and pollutants in the resin tank.

[0034] At the same time, the ejector starts to generate negative pressure, sucking air into the ozone generator. Under the action of the high voltage electric field, the ionization chamber inside the ozone generator ionizes the oxygen molecules in the air to form oxygen atoms, which combine with the surrounding oxygen molecules to form ozone molecules.

[0035] Exemplarily, when in the strong sterilization mode, if it is detected that the remaining softened water volume of the water treatment equipment is greater than the preset 60% cycle water output, and the shutdown time of the water treatment equipment is greater than 15 days, the water treatment equipment control valve head rotates to perform the brine regeneration step, and at the same time, the sodium hypochlorite generator is turned on to control the sodium hypochlorite generator to enter the salt absorption step. At this time, the working time of the sodium chlorate generator is the same as the salt absorption time. The sodium chlorate solution generated by the sodium hypochlorite generator absorbing salt is used to perform preliminary sterilization on the water treatment equipment. After the sodium hypochlorite generator ends, the ozone generator and its control valve are immediately opened to allow the ozone generator to run for a preset time so that the ozone can deeply sterilize the resin tank. After the sterilization is completed, the ozone generator and its control valve are closed, and the wastewater is discharged through the wastewater discharge pipe after the slow wash, backwash, and forward wash are completed.

[0036] Exemplarily, when the remaining softened water volume is less than 60% of the preset cycle water production, and the shutdown time of the water treatment equipment has been greater than 7 days and less than 15 days without monitoring the flow signal or electrical signal, the valve head of the water treatment equipment rotates to perform the brine regeneration step. When entering the salt absorption step, the sodium hypochlorite generator is simultaneously turned on to generate sodium hypochlorite solution to sterilize the resin tank, and then the slow wash, backwash, and forward wash execution processes are completed to discharge the wastewater through the wastewater discharge pipe.

[0037] based on Figure 1 The scene diagram shown below will be combined with Figure 2-Figure 8 , a sterilization control method provided in an embodiment of the present application is introduced in detail.

[0038] Based on the above situation, the present application embodiment proposes a sterilization control method. Figure 2 , Figure 2 Schematic diagram of a sterilization control method provided in the embodiment of the present application. Figure 2 As shown, the method of the embodiment of the present application may include the following steps S101-S103.

[0039] S101, obtaining status operation parameters of water treatment equipment.

[0040] In an embodiment of the present application, the status operation parameters may at least include the remaining softened water volume of the water treatment equipment, the downtime duration, the time since the last electrolysis was started, and the water volume in the resin tank, wherein the remaining softened water volume is the water volume that has been softened but not yet used in the water treatment equipment; the downtime duration is the time from the last operation end to the current time when the water treatment equipment stops running; the time since the last electrolysis was started refers to the interval from the last electrolysis process end to the current time when the water treatment equipment starts; the water volume in the resin tank reflects the current state of the resin and the processing capacity of the equipment.

[0041] Specifically, the operating data of the water treatment equipment, including but not limited to the remaining softened water volume, downtime, time since the last electrolysis start, and water volume in the resin tank, are monitored and recorded in real time through the built-in sensors and metering devices of the water treatment equipment. These data are transmitted to the control unit or cloud server through the built-in communication module. Subsequently, the control unit or cloud server integrates and analyzes these data to generate status operating parameters.

[0042] S102, if the state operation parameters meet the preset first operation condition, the water treatment equipment is controlled to operate in the slow wash mode, and the ozone generator is controlled to enter the operation state to sterilize the water treatment equipment, and the water treatment equipment is controlled to switch from the slow wash mode to the forward and backwash mode.

[0043] In the embodiment of the present application, the first operating condition can be set according to actual usage requirements. The following is explained using the remaining soft water volume and shutdown time of the water treatment equipment as the first operating condition.

[0044] Specifically, the remaining soft water volume and shutdown time of the water treatment equipment are extracted from the state operation parameters. If it is detected that the remaining soft water volume is greater than the preset cycle soft water volume and the shutdown time of the water treatment equipment is greater than the preset first shutdown time, the water treatment equipment is controlled to enter the first strong sterilization mode.

[0045] In the first strong sterilization mode, the water treatment equipment is controlled to enter the slow wash mode. In this mode, the water treatment equipment will clean the inside of the water treatment equipment at a lower flow rate and a specific cleaning procedure. At the same time, the ozone generator is also activated and starts to work to generate ozone gas to sterilize the water treatment equipment. After the slow wash mode and the sterilization process are completed, the water treatment equipment is further controlled to switch from the slow wash mode to the forward and backwash mode after running for a preset time. In the forward and backwash mode, the water treatment equipment can effectively remove impurities and particulate matter that may remain inside the equipment through alternating forward and reverse water flow, and finally complete the entire cleaning and sterilization process of the water treatment equipment, ensuring the efficient operation of the water treatment equipment and the continuous optimization of water quality.

[0046] Based on the first operating condition, if it is detected that the remaining soft water amount is greater than the preset cycle soft water amount, the water treatment equipment is controlled to enter the first conventional sterilization mode when the shutdown time is greater than the preset first shutdown time and greater than the second shutdown time.

[0047] In the first conventional sterilization mode, the water treatment equipment is controlled to enter the slow wash mode to control the water treatment equipment to clean the inside of the water treatment equipment at a lower flow rate and a preset cleaning program. At the same time, the ozone generator is controlled to run and stop after working for a preset time. At this time, the water treatment equipment continues to be controlled to run in the slow wash mode for a preset time and then enter the forward and reverse wash mode, and after detecting that the forward and reverse wash mode has been completed, the wastewater in the water outlet equipment is discharged. In this process, the working time of the ozone generator must be less than the working time of the ozone generator 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.

[0048] S103, if the state operation parameter meets the preset second operation condition, the sodium hypochlorite generator is controlled to operate to sterilize the water treatment equipment, and after the water treatment equipment is controlled to enter the slow wash mode and operate for a preset time, the water treatment equipment is controlled to switch from the slow wash mode to the forward and backwash mode.

[0049] In the embodiment of the present application, the second operating condition can be set according to actual usage requirements. The following is an explanation of the second operating condition using the remaining soft water volume and shutdown time of the water treatment equipment.

[0050] Specifically, if the remaining soft water volume is less than the preset cycle soft water volume and the shutdown time is longer than the first time, the water treatment equipment is controlled to enter the second strong sterilization mode.

[0051] In the second strong sterilization mode, the water treatment equipment is controlled to turn on the sodium chlorate generator to generate sodium hypochlorite solution. During this process, if the brine capacity in the water treatment equipment is insufficient, the brine regeneration step is performed to provide the sodium chlorate generator with sufficient brine. After detecting that the sodium chlorate generator has finished running, the ozone generator will be controlled to run for a preset time to further deeply sterilize the water treatment equipment. After the ozone generator is sterilized, it is turned off, and the water treatment equipment is controlled to enter the slow wash mode. After the water treatment equipment has been in the slow wash mode for a preset time, the water treatment equipment is further controlled to switch to the forward and reverse wash mode. After the forward and reverse wash mode is completed, the water treatment equipment is controlled to stop running, thereby completing the entire sterilization and cleaning process to ensure the efficient and safe operation of the water treatment equipment.

[0052] Based on the first operating condition, when it is detected that the remaining soft water volume is less than the preset cycle soft water volume and the shutdown time is less than the first time and the second time, the water treatment equipment is controlled to enter the second conventional sterilization mode.

[0053] In the second conventional sterilization mode, the water treatment equipment will first start the sodium hypochlorite generator, put it into operation and absorb salt water to generate sodium hypochlorite solution to sterilize the resin tank of the water treatment equipment. After confirming that the sodium hypochlorite generator has finished running, the water treatment equipment is controlled to enter the slow wash mode. The water treatment equipment will continue to run for a preset time in the slow wash mode to ensure thorough cleaning of the inside of the equipment. After the slow wash mode ends, the water treatment equipment is controlled to switch to the forward and reverse wash mode, and the impurities that may remain inside the equipment are further removed by alternating forward and reverse water flow. Finally, after the forward and reverse wash mode is completed, the wastewater is discharged and the water treatment equipment is controlled to stop running to complete the entire sterilization and cleaning process.

[0054] As can be seen from the above, by obtaining the status operating parameters, the equipment status can be accurately judged. When the first operating condition is met, the slow wash mode combined with ozone sterilization can effectively remove impurities and sterilize thoroughly, and then switch to the forward and reverse wash mode to ensure that the equipment is fully cleaned. When the second operating condition is met, the sodium hypochlorite generator is controlled to perform slow wash and then forward and reverse wash after sterilization, and the strong oxidizing property of sodium hypochlorite is used to further ensure the sterilization effect, thereby improving the overall water treatment quality and efficiency and improving the user's water safety.

[0055] Since water treatment equipment may not be used for a long time in actual use scenarios, the internal environment of the water treatment equipment is relatively poor when the water treatment equipment fails to start for a long time. Therefore, the water treatment equipment needs to be automatically cleaned and sterilized according to the actual scenario. Figure 3 , Figure 3 Schematic diagram of a sterilization control method provided in the embodiment of the present application. Figure 3 As shown, the method of the embodiment of the present application may include the following steps S201-S206.

[0056] S201, extracting the remaining soft water volume and downtime duration of the water treatment equipment from the state operation parameters.

[0057] Specifically, the state operation parameters of the water treatment equipment are obtained by accessing the local storage unit or the cloud service end, and the data items related to the remaining soft water volume are extracted from the state operation parameters. This data can directly represent the specific value of the remaining soft water volume in digital form, or it can be an indirect result obtained through a series of calculations (such as calculated based on the total amount of water inflow, the amount of water treated, and other related data). In the same way, the data of the downtime of the water treatment equipment is obtained from the state operation parameters. The record of the downtime can be calculated based on the difference between the time point when the water treatment equipment stops running and the time point when it stopped running last, or it can be accumulated and recorded from the moment the equipment stops running through a special timing device.

[0058] Exemplarily, the remaining soft water volume extracted from the state operating parameters is 500 liters, and the shutdown time is 5 days.

[0059] S202, if the remaining soft water volume is greater than the preset cycle soft water volume, the water treatment equipment is controlled to enter the slow wash mode when the shutdown time is greater than the preset first shutdown time, and the ozone generator is controlled to enter the operating state.

[0060] Specifically, the extracted remaining soft water volume data is compared with the preset cycle soft water volume data, wherein the preset cycle soft water volume is a standard value pre-set according to factors such as the design specifications, processing capacity and normal operating cycle of the water treatment equipment, and is used to measure whether the current remaining soft water volume of the equipment is at a normal level or requires special treatment, and is not specifically limited here.

[0061] If the comparison result shows that the remaining soft water volume is greater than the preset cycle soft water volume and the downtime is greater than the preset first downtime, a command is sent to the control unit of the water treatment equipment to make it enter the slow wash mode. In the slow wash mode, the water flow rate, flushing method and other parameters inside the equipment are adjusted according to the pre-set slow wash program, such as reducing the water flow rate, extending the flushing time, etc., to achieve a better cleaning effect.

[0062] At the same time, a start signal is sent to the ozone generator, triggering it to start working, preparing to use the strong oxidizing properties of ozone to sterilize the resin tank of the water treatment equipment.

[0063] S203: If the working time of the ozone generator is equal to the first working time, the ozone generator is controlled to stop running.

[0064] Specifically, the timer corresponding to the ozone generator is enabled to continuously monitor the running time of the ozone generator. When it is monitored that the working time of the ozone generator reaches the preset first working time, wherein the first working time is an optimal running time determined comprehensively based on factors such as the performance of the ozone generator, the effective dose required for sterilization, and the size of the internal space of the equipment, and is not specifically limited here, a stop operation instruction is sent to the ozone generator to stop the ozone generator from generating ozone and end the current sterilization process to prevent excessive ozone generation from causing potential damage to the equipment or waste of resources.

[0065] Exemplarily, the ozone generator starts to work, and the timer starts to run. When the ozone generator runs for 60 minutes (reaching the first working time), the ozone generator is controlled to stop running.

[0066] S204, after the water treatment device runs in the slow wash mode for a second working time, the water treatment device is controlled to enter the forward and reverse wash mode, and after the forward and reverse wash mode is completed, the water treatment device is controlled to stop running.

[0067] Specifically, after the ozone generator is turned off, the treatment equipment is controlled to enter the slow wash mode, and a timer associated with the slow wash mode is started to start calculating the running time of the slow wash mode. When the running time of the slow wash mode reaches the preset second working time, an instruction is sent to the control unit of the water treatment equipment to switch from the slow wash mode to the forward and backwash mode. In the forward and backwash mode, the water treatment equipment changes the direction of the water flow, first reverse flushes to flush the dirt and residual substances deep inside the equipment to the outlet end, and then forward flushes to completely discharge the impurities from the water treatment equipment. Among them, the second working time is an appropriate time length determined based on factors such as research on the cleaning effect of dirt and impurities inside the equipment and the connection requirements for subsequent forward and backwash modes. It is not specifically limited here.

[0068] S205, if the remaining soft water volume is greater than the cycle soft water volume, the water treatment equipment is controlled to enter the slow wash mode when the shutdown time is less than the first shutdown time and greater than the second shutdown time, and the ozone generator is controlled to stop running after running for the third working time, and the second time is less than the first time.

[0069] Specifically, the same as the execution steps in S202 above, the extracted remaining soft water amount is compared with the preset cycle soft water amount again, and when it is confirmed that the remaining soft water amount is greater than the cycle soft water amount and the shutdown time is less than the first shutdown time and greater than the second shutdown time, the first conventional sterilization mode is entered, that is, a control instruction is sent to the water treatment equipment to enter the slow wash mode. At the same time, a start instruction is sent to the ozone generator to start it, and the operation timer matching the ozone generator is started.

[0070] When the running time of the ozone generator reaches the pre-set 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 time range and the equipment sterilization requirements, and is not specifically limited here.

[0071] S206, controlling the water treatment device to run in the slow wash mode for a fourth preset time and then enter the forward and reverse wash mode, and controlling the water treatment device to stop running after the forward and reverse wash mode is completed.

[0072] Specifically, after the ozone generator stops running, the timer associated with the slow wash mode is started to start calculating the running time of the water treatment device in the current slow wash mode. When the running time of the slow wash mode reaches a preset fourth preset time, the water treatment device is controlled to switch from the slow wash mode to the forward and reverse wash mode, wherein the fourth preset time is a time length determined based on a comprehensive consideration of the cleaning effect of the equipment and the subsequent forward and reverse wash mode preparation, and is not specifically limited here.

[0073] After the forward and backwash modes are detected to be executed, a stop operation instruction is sent to the water treatment equipment to end the operation process of the entire water treatment equipment. At this time, the water treatment equipment is in a standby state.

[0074] Exemplarily, the remaining soft water volume of the water treatment equipment is 120 cubic meters, but the shutdown time is 20 days. At this time, 120 cubic meters is greater than 100 cubic meters (the remaining soft water volume is greater than the periodic soft water volume), and 20 days is less than 30 days (the shutdown time is less than the first shutdown time) and greater than 15 days (greater than the second shutdown time). Then the water treatment equipment is controlled to enter the slow wash mode, and the ozone generator is started to run for 30 minutes (the third working time) and then stop running. After the ozone generator stops, the water treatment equipment runs in the slow wash mode for 35 minutes (the fourth preset time), and then enters the forward and reverse wash mode, and stops running after the forward and reverse wash is completed.

[0075] Please also read Figure 4 , Figure 4 Schematic diagram of a sterilization control method provided in an embodiment of the present application. Figure 4 As shown: when the remaining soft water volume is greater than the preset cycle soft water volume, it is determined whether the downtime is greater than the first time length. If the downtime is greater than the first time length, the first strong sterilization mode will be executed, that is, the execution process of S202-S204 will be executed; if the downtime is not greater than the first time length, it is further determined whether the downtime is greater than the second time length. If the downtime is greater than the second time length, the first conventional sterilization mode will be executed, that is, the execution process of S205-S206 will be executed.

[0076] From the above, we can know that by choosing whether to enter the slow wash mode and controlling the running time of the ozone generator according to the remaining soft water volume and downtime, it can effectively prevent the growth of bacteria inside the equipment and ensure the cleanliness and safety of water quality; on the other hand, it can avoid the waste of resources and equipment loss caused by excessive operation of equipment such as ozone generators. At the same time, through the reasonable switching of slow wash and forward and reverse wash modes, it can ensure that the inside of the equipment is fully cleaned, maintain the good operating state of the equipment, and extend the service life of the equipment.

[0077] To further improve the cleaning efficiency of water treatment equipment. Figure 5 , Figure 5 Schematic diagram of a sterilization control method provided in the embodiment of the present application. Figure 5 As shown, the method of the embodiment of the present application may include the following steps S301-S309.

[0078] S301, extracting the remaining soft water volume and downtime duration of the water treatment equipment from the state operation parameters.

[0079] Specifically, the specific execution process of S301 please refer to the above S201, which will not be repeated here.

[0080] S302: If the remaining soft water volume is less than the preset period soft water volume, the sodium hypochlorite generator is controlled to enter the running state when the shutdown time is longer than the first time.

[0081] Specifically, if the remaining soft water volume is less than the preset cycle soft water volume, the downtime duration is then compared with the first duration. If the downtime duration is greater than the first duration, the water treatment equipment is controlled to enter the second strong sterilization mode. At this time, the sodium hypochlorite generator is controlled to enter the operating state and prepare for sterilization operations.

[0082] S303, generating a sodium hypochlorite solution based on a sodium hypochlorite generator to sterilize water treatment equipment.

[0083] Specifically, when the sodium hypochlorite generator receives the salt water generated by absorption and is acted upon by an electric field, the chloride ions in the salt water migrate to the anode, where they lose electrons on the anode surface and are oxidized to generate chlorine. At the same time, the hydrogen ions ionized from the water gain electrons at the cathode and are reduced to generate hydrogen, which escapes from the cathode. The hydrogen ions continuously gain electrons near the cathode to generate hydrogen, which destroys the ionization balance of the water, causing more hydroxide ions to be generated near the cathode, forming an alkaline environment. The generated chlorine reacts with the hydroxide ions to generate hypochlorite ions, which combine with the sodium ions to form a sodium hypochlorite solution.

[0084] The generated sodium hypochlorite solution is transported through pipelines to the resin tank and other areas of the water treatment equipment that need to be sterilized, so that the sodium hypochlorite can be oxidized and killed by its strong oxidizing property, thereby achieving the sterilization effect on the water treatment equipment.

[0085] S304, if it is detected that the sodium chlorate generator has finished running, the ozone generator is controlled to run for a fifth preset time and then shut down, and the water treatment equipment is controlled to enter a slow wash mode.

[0086] Specifically, the operating status monitoring program for the sodium hypochlorite generator is started, and the parameters such as the current, voltage, temperature, and the progress of the internal chemical reaction (such as the brine consumption rate, the amount of chlorine produced, and other indirect indicators) of the sodium hypochlorite generator are monitored to determine whether the sodium hypochlorite generator has completed operation. When it is detected that the sodium hypochlorite generator has completed operation, the operation of the ozone generator is controlled for the fifth preset time. At the same time, an instruction is sent to the valve control module of the water treatment equipment to adjust the valve state, so that the water treatment equipment enters the slow wash mode to prepare for subsequent cleaning operations.

[0087] S305, after the water treatment device runs in the slow wash mode for a sixth preset time, the water treatment device is controlled to enter the forward and reverse wash mode, and after the forward and reverse wash mode is completed, the water treatment device is controlled to stop running.

[0088] Specifically, the water treatment equipment is controlled to enter the slow wash mode and a timer associated with the slow wash mode is started to start recording the running time of the slow wash mode. During the slow wash process, the water flow in the water treatment equipment circulates in the resin tank and other components at a lower speed and in a specific flow direction. The water flow takes away some residual fungicides and other impurities, but does not cause excessive impact on the equipment.

[0089] When the slow wash time recorded by the timer reaches the sixth preset time, an instruction is sent to the valve control module of the water treatment equipment to switch the valve state so that the equipment enters the forward and reverse wash mode from the slow wash mode.

[0090] In forward and reverse flushing mode, the equipment first performs reverse flushing, and the water flow direction is opposite to that in normal operation, flushing impurities deep inside the resin tank to the outlet. Then forward flushing is performed to completely discharge the impurities flushed out by reverse flushing and other residual impurities in the equipment.

[0091] The water quality, pressure, flow rate and other parameters of the drainage are further monitored to determine whether the forward and reverse wash modes have been completed. When these parameters reach the preset standards (such as clear drainage, stable pressure, normal flow rate, etc.), a stop operation command is sent to the control unit of the water treatment equipment to stop the equipment and complete the sterilization process.

[0092] S306: If the remaining soft water volume is less than the preset cycle soft water volume, the sodium hypochlorite generator is controlled to enter the running state when the shutdown time is less than the first time and the second time.

[0093] Specifically, if the remaining soft water volume is less than the preset cycle soft water volume and the shutdown time is less than the first time and the second time, the water treatment equipment is controlled to enter the second conventional sterilization mode. At this time, the sodium hypochlorite generator is controlled to enter the operating state and prepare for the sterilization operation. The first time and the second time can be set according to the actual scenario and are not specifically limited here.

[0094] S307, generating a sodium hypochlorite solution based on a sodium hypochlorite generator to sterilize the water treatment equipment.

[0095] Specifically, the specific execution process of S307 please refer to the above S303, which will not be repeated here.

[0096] S308: If it is detected that the sodium chlorate generator has finished operating, the water treatment equipment is controlled to enter a slow wash mode.

[0097] Specifically, the operating status monitoring program for the sodium hypochlorite generator is started to determine whether the sodium hypochlorite generator has completed operation by monitoring the generator's current, voltage, temperature and other parameters, as well as the progress of the internal chemical reaction (such as the brine consumption rate, chlorine production and other indirect indicators). When it is detected that the sodium hypochlorite generator has completed operation, a command is sent to the valve control module of the water treatment equipment to put the water treatment equipment into slow washing mode to prepare for subsequent cleaning work.

[0098] S309, after the water treatment device runs in the slow wash mode for a seventh preset time, the water treatment device is controlled to enter the forward and reverse wash mode, and after the forward and reverse wash mode is completed, the water treatment device is controlled to stop running.

[0099] Specifically, after the water treatment equipment runs in the slow wash mode for the seventh preset time, it switches to the forward and reverse wash mode for reverse and forward washing to remove residual impurities in the equipment. When it is detected that the backwash mode is completed, a stop operation instruction is sent to the water treatment equipment to stop the equipment and end the current treatment process.

[0100] Exemplarily, the seventh preset time length is 30 minutes. After detecting that the water treatment equipment has been running in the slow wash mode for 30 minutes, the water treatment equipment is controlled to enter reverse and forward flushing and work for 15 minutes, and then the waste water is discharged and the water treatment equipment is controlled to stop running.

[0101] Please also read Figure 6 , Figure 6 Schematic diagram of a sterilization control method provided in an embodiment of the present application. Figure 6 As shown: when the remaining soft water volume is less than the preset cycle soft water volume, it is determined whether the downtime duration is greater than the first duration. If the downtime duration is less than the first duration, if it is less than the first duration, the above-mentioned S302-S305 execution process is executed. If it is less than the first duration, and if it is less than the second duration, the above-mentioned S306-S309 execution process is executed, which will not be repeated here.

[0102] From the above, we can know that by choosing whether to enter the slow wash mode and controlling the running time of the ozone generator according to the remaining soft water volume and downtime, it can effectively prevent the growth of bacteria inside the equipment and ensure the cleanliness and safety of water quality; on the other hand, it can avoid the waste of resources and equipment loss caused by excessive operation of equipment such as ozone generators. At the same time, through the reasonable switching of slow wash and forward and reverse wash modes, it can ensure that the inside of the equipment is fully cleaned, maintain the good operating state of the equipment, and extend the service life of the equipment.

[0103] Because the traditional water softener sterilization method may not be thorough, such as relying on a single sterilization method or failing to allow the sterilizer to fully contact all parts of the resin tank. Figure 7 , Figure 7Schematic diagram of a sterilization control method provided in the embodiment of the present application. Figure 7 As shown, the method of the embodiment of the present application may include the following steps S401-S402.

[0104] S401, extracting a preset amount of dissolved salt from a salt tank, and fusing the dissolved salt with a preset volume of water in a water treatment device to generate salt water.

[0105] Specifically, relevant information about the dissolved salt in the salt box is obtained, such as the amount of salt, the distribution state of the salt, etc. Then, according to the preset quantity requirement, the corresponding extraction device is started, wherein the extraction device can be a suction pump with a metering function or a mechanical salt extraction device, which can accurately take out a specified amount of dissolved salt from the salt box. During the extraction process, factors such as the fluidity and agglomeration of the salt are considered. If there are agglomerates, they need to be broken or dispersed first to ensure that the preset amount of dissolved salt can be extracted smoothly.

[0106] At the same time, by adjusting the pipeline control valve to obtain a preset volume 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 brine solution.

[0107] S402, based on the sodium hypochlorite generator absorbing salt water to generate sodium hypochlorite solution, the resin tank is sterilized based on the sodium hypochlorite solution.

[0108] Specifically, while the salt water is being generated, the sodium hypochlorite generator is controlled to operate and the salt water is transported to the sodium hypochlorite generator. There are specific electrolysis devices and reaction chambers inside the sodium hypochlorite generator. After the salt water enters the reaction chamber, a chemical reaction begins to occur under the action of the electrolysis device.

[0109] During the electrolysis process, anions migrate to the anode and cations migrate to the cathode. Near the anode, chloride ions lose electrons and are oxidized to generate chlorine gas; near the cathode, hydrogen ions gain electrons and are reduced to generate hydrogen gas. Hydrogen ions generate hydrogen gas at the cathode, destroying the ionization balance of water, producing more hydroxide OH- to form an alkaline environment. Chlorine gas generates hypochlorite in an alkaline environment, and hypochlorite combines with sodium ions to form a sodium hypochlorite solution.

[0110] The generated sodium hypochlorite solution is introduced into the resin tank through a pipe. The resin tank is filled with resin used to soften water. These resins are prone to breed bacteria and microorganisms during long-term use, affecting the softening effect and water quality safety. After the sodium hypochlorite solution enters the resin tank, it uses its strong oxidizing property to kill and disinfect the bacteria and microorganisms on the resin surface and in the tank.

[0111] From the above, we can see that 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 the preset procedures and parameters. This helps to improve the intelligence 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.

[0112] Since traditional water treatment equipment sterilization control cannot control the sterilization process according to the user's actual water use habits and equipment usage, it affects the sterilization efficiency. Figure 8 , Figure 8 Schematic diagram of a sterilization control method provided in the embodiment of the present application. Figure 8 As shown, the method of the embodiment of the present application may include the following steps S501-S503.

[0113] S501, obtaining status operation parameters of water treatment equipment.

[0114] Specifically, for the specific execution process of S501, please refer to the above S101 and will not be repeated here.

[0115] S502, obtaining water usage data of the user for the water treatment equipment, where the water usage data includes water usage duration and water stop duration.

[0116] In the embodiment of the present application, the water treatment equipment is connected to the water treatment equipment through flow sensors, smart water meters and other devices installed in the water inlet pipeline of the water treatment equipment or the user's water terminal. These devices can monitor and record the flow of water in real time. At the same time, they may also work with the built-in timer of the equipment to accurately record the duration of water use and water stop.

[0117] Specifically, when the user starts to use water, the flow sensor detects the water flow signal and transmits the signal to the water use timer of the water treatment equipment. The water use timer starts to record the water use time, and continues to accumulate from the moment the water flow starts to flow until the water flow stops. The accumulated time at this time is the water use time of this time.

[0118] After the user stops using water, the water use timer records the time when water use stops. The water use timer starts counting from the moment water use stops, and continues until the next water use starts or the end of the preset statistical period. If the user starts using water again during the statistical period, the timing of the water use stop time is paused, and the interim data of the water use stop time is recorded. When the statistical period ends (such as one day, one week, etc.), the accumulated water use stop time data is sorted and stored for subsequent analysis.

[0119] S503, determining the working hours of the ozone generator and the sodium chlorate generator based on the water usage data.

[0120] Specifically, the acquired water use time and water stop time data are substituted into the association model for calculation. The association model can calculate the appropriate working time of the ozone generator and the sodium chlorate generator under the current circumstances according to the input data, according to the preset algorithm and logical rules. Among them, the association model can specifically include a linear regression model, a decision tree model and a neural network model, which are not specifically limited here.

[0121] According to the calculation results, the final working time of the ozone generator and the sodium chlorate generator is determined. At the same time, the current state of the water treatment equipment, the remaining resources (such as the amount of salt in the salt box, the energy consumption of the ozone generator, etc.) and other external factors (such as ambient temperature, initial water quality, etc.) are considered to make appropriate adjustments and optimizations to the calculation results. For example, if the amount of salt in the salt box is low, the working time of the sodium chlorate generator may be appropriately shortened to avoid excessive consumption of salt resources; if the ambient temperature is high and the bacterial reproduction rate is accelerated, the working time of the ozone generator may be appropriately extended to ensure the sterilization effect. The final working time will be sent to the corresponding generator as a control instruction, so that it can run according to the set time to achieve precise sterilization of the water treatment equipment.

[0122] From the above, we can see that by obtaining water use data such as the length of time users use water for water treatment equipment and the length of time they stop using water, a key basis is provided for subsequent precise control. The working hours of the ozone generator and the sodium chlorate generator are determined based on these water use data, which solves the problem of the lack of targeted sterilization control of traditional water treatment equipment. It can avoid the waste of resources and equipment loss caused by excessive sterilization based on the actual water use habits and equipment usage of users, while ensuring that sufficient sterilization treatment is provided when necessary. This helps to improve sterilization efficiency, ensure that the water quality is always in good condition, extend the service life of the equipment, reduce operating costs, and improve the user experience.
