Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, 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.

[0022] The cleaning control method and water treatment equipment provided in this application will be described in detail below through several specific embodiments.

[0023] Example 1 This embodiment provides a cleaning control method, which is applied to, for example... Figure 1 The water treatment equipment shown can be a water purifier or a water dispenser.

[0024] like Figure 1As shown, the water treatment equipment includes an inlet pipe 10, a filter assembly 20, a water tank 30, and a controller for executing the cleaning control method. The inlet of the filter assembly 20 is connected to the raw water inlet of the water treatment equipment via the inlet pipe 10. The clean water outlet of the filter assembly 20 is connected to the first inlet of the water tank 30. An outlet pipe 40 is provided between the outlet of the water tank 30 and the faucet outlet of the water treatment equipment. A cleaning pipe 50 is connected between the inlet of the filter assembly 20 and the outlet of the water tank 30. The other end of the cleaning pipe 50 is connected to the inlet of the filter assembly 20 via the inlet pipe, and one end of the cleaning pipe 50 is connected to the outlet of the water tank 30 via the outlet pipe.

[0025] In some embodiments, a pre-filter 103 may be provided upstream of the inlet pipe 10, with one end of the pre-filter being the inlet of the water treatment equipment, i.e., the raw water inlet, for connecting to the raw water source. When water production is required, the raw water provided by the raw water source is first filtered by the pre-filter 103, and then enters the filter assembly 20 through the inlet pipe 10 for further filtration. The wastewater is then discharged through the wastewater outlet of the filter assembly 20, and the resulting purified water flows into the water tank 30 through the purified water outlet of the filter assembly 20.

[0026] The filter element 20 can be an RO filter cartridge. The water tank 30 can be a normal temperature water tank 30 for storing filtered room temperature water, that is, storing clean water that is relatively close to room temperature.

[0027] Fluid control elements, such as solenoid valves and / or water pumps, can be installed on the inlet pipe 10, outlet pipe 40, and cleaning pipe 50 to control the opening and closing of the pipes and the pumping of water. Fluid control elements can also be installed on the wastewater outlet and the clean water outlet of the filter assembly 20, such as a wastewater valve at the wastewater outlet and a solenoid valve at the clean water outlet, to control the inlet and outlet of the filter assembly.

[0028] Based on the aforementioned water treatment equipment, the cleaning control method includes: Based on the operating time of the water treatment equipment, control the water output from the water tank and clean at least one of the water tank's outlet pipes and filter components.

[0029] The runtime starts from the time the water treatment equipment is powered on, and is the time during which the equipment continues to work after being powered on.

[0030] Specifically, the water tank outlet is controlled to clean the filter assembly 20 and / or outlet pipe 40 based on the operating time of the water treatment equipment, including: When the water treatment equipment is detected to have reached the first operating time, water is controlled to flow from water tank 30 to clean the filter component 20. When the water treatment equipment is detected to have reached the second operating time, the water tank 30 is controlled to discharge water, and the water outlet pipe 40 is cleaned.

[0031] The above cleaning process is cyclical. For example, the first running time is 5 hours and the second running time is 24 hours. Every 5 hours, the water tank 30 is controlled to discharge water to clean the filter component 20, and every 24 hours, the water tank 30 is controlled to discharge water to clean the water outlet pipe 40.

[0032] This allows for regular cleaning of the water system during the water treatment equipment's operating cycle, improving the growth of bacteria and scale, maintaining a clean water system, and ensuring the quality of the water output from the water treatment equipment.

[0033] Furthermore, the filter assembly and the outlet pipe are connected in parallel with the water tank. During cleaning, the filter assembly can be cleaned independently with the clean water in the water tank, and the outlet pipe of the water tank can also be cleaned independently. The cleaning processes of the filter assembly and the outlet pipe will not interfere with each other, ensuring the consistency of the cleaning of the filter assembly and the outlet pipe, thereby improving the cleaning effect.

[0034] Furthermore, the water outlet pipe directly flushes the faucet outlet, ensuring effective flushing of the water outlet pipe and the faucet outlet, and avoiding the impact of residual water in the pipe on the quality of the water.

[0035] It should be noted that the first and second running times can be the same or different. When the first and second running times are the same, the water tank outlet is controlled, and the filter components and outlet pipes are cleaned simultaneously.

[0036] Preferably, before controlling the water flow from the water tank, the process also includes disinfecting the purified water in the water tank.

[0037] This ensures that the purified water pumped from the water tank is sterile, thereby achieving sterile cleaning of the filter components and water outlet pipes and improving the cleaning effect of the water treatment equipment.

[0038] In this embodiment, disinfecting the purified water in the water tank includes disinfecting the purified water in the water tank according to the operating time of the water treatment equipment. This facilitates the disinfection of the purified water in the water tank before cleaning the filter components and the outlet pipe, ensuring that the water used to clean the filter components and the outlet pipe is disinfected and sterile.

[0039] Disinfection of the purified water in the tank is performed based on the operating time of the water treatment equipment, including: When the water treatment equipment is detected to have reached its third operating time, the purified water in the water tank is disinfected.

[0040] The above disinfection process is a cyclical process. For example, the third run lasts 25 minutes, and the water treatment equipment disinfects the purified water in the tank every 25 minutes. This timed sterilization of the tank ensures that the purified water in tank 30 remains sterile. This also allows for sterile rinsing of the outlet pipe 40 and / or filter assembly 20 at any time.

[0041] In other embodiments, the purified water in the water tank is disinfected, including: When the water treatment equipment is detected to have reached the first or second operating time, the purified water in the water tank 30 is first disinfected. After the predetermined sterilization time is reached, the water tank 30 is then controlled to discharge water to clean the filter assembly 20 or the water outlet pipe 40.

[0042] The methods for disinfecting the purified water in the water tank are existing technologies, such as ultraviolet (UV) lamp sterilization, UV lamp + titanium dioxide catalytic mesh sterilization, and silver ion sterilization. Taking UV lamp sterilization as an example, a UV sterilization component is installed in the water tank 30 to sterilize the water in the tank by timed activation or as needed.

[0043] In this embodiment, the cleaning control method further includes: Based on the status parameters of the water treatment equipment, the water output from the water tank 30 is controlled to clean the filter assembly 20.

[0044] The above status parameters describe the water treatment equipment's influent and water production conditions during operation, including influent TDS, production time, and production volume. Influent TDS refers to the TDS (Total Dissolved Solids) of the raw water flowing in through influent pipe 10, indicating the pollution level of the raw water; production time refers to the time it takes for the filter components to produce purified water; and production volume refers to the amount of purified water produced by the filter components.

[0045] Because raw water entering the water purifier introduces impurities and microorganisms from the raw water into the water treatment system, it contaminates the filter components and affects the overall cleanliness of the system. The equipment's inlet and outlet water volumes are dynamically adjusted based on user usage. By collecting parameters corresponding to these volumes, the contamination level of the filter components can be detected and predicted in a timely manner, prompting prompt cleaning of the filter components. This ensures both the filtration effect and the cleanliness of the filtered water, while also reducing bacterial growth on the filter components.

[0046] Based on the status parameters of the water treatment equipment, the water output from the water tank 30 is controlled to clean the filter assembly 20, specifically as follows: Based on at least one of the following: influent TDS, water production time, or water production volume of the water treatment equipment, the water output from the water tank 30 is controlled to clean the filter assembly 20.

[0047] For example, a preset TDS can be set, such as 300 mg / L; a preset water production time can be set, such as 5 minutes; and a preset water production volume can be set, such as 1.2L.

[0048] The TDS of the influent to the water treatment equipment is detected. When the influent TDS is greater than or equal to the preset TDS, the water tank is controlled to discharge water after the water production is completed, and the filter component 20 is cleaned.

[0049] When the TDS of the influent is less than the preset TDS, and the cumulative water production time reaches the preset water production time, the water tank is controlled to discharge water to clean the filter component 20. Alternatively, when the influent TDS is less than the preset TDS and the cumulative water production reaches the preset water production, the water tank is controlled to discharge water to clean the filter component 20.

[0050] When the TDS of the influent is less than the preset TDS, the filter component 20 will be cleaned every time the cumulative water production time reaches the preset water production time or the cumulative water production volume reaches the preset water production volume.

[0051] In other implementations, status parameters such as idle time, power-on status, cleaning trigger time, and operating mode of the water treatment equipment can be collected. Based on these status parameters, the operating status of the water treatment equipment can be determined, and the cleaning process of the water treatment equipment can be judged and controlled according to different operating statuses.

[0052] For example, based on the idle time of the water treatment equipment, the water output from the tank is controlled to clean the filter assembly 20. The idle time is the continuous period during which no water is produced, such as 24 hours. When the idle time is detected to have reached 24 hours, the water output from the tank is controlled to clean the filter assembly 20. This prevents the water treatment equipment from being idle for too long, which could lead to the growth of bacteria in the water stored in the filter assembly.

[0053] For example, based on the power-on status of the water treatment equipment, water can be dispensed from the tank to clean the filter assembly 20. The power-on status refers to the state after the equipment has been powered off and then re-energized. When the re-energization is detected, water is dispensed from the tank to clean the filter assembly 20. This reduces the impact of impurities accumulating on the filter assembly 20 during power outages on the filtration effect, thereby improving the safety of water used in the water treatment equipment.

[0054] For example, based on the cleaning trigger time of the water treatment equipment, the water tank is controlled to discharge water to clean the filter component 20. The cleaning trigger time refers to a preset cleaning time, such as 2:00 AM. When the current time is detected as the cleaning trigger time of the water treatment equipment, the water tank 30 is controlled to discharge water to clean the water outlet pipe 40.

[0055] For example, based on the water treatment equipment's operating mode, the system controls water flow from the tank to clean the filter assembly 20. Operating modes include a working mode and a vacation mode. The working mode refers to the normal operating mode after the water treatment equipment is powered on, where the equipment produces and purifies water according to user usage. The vacation mode is an intelligent mode designed for users who are away for extended periods. When the vacation mode is detected, the system controls water flow from the tank to clean the filter assembly 20. This reduces the risk of bacterial contamination of the filter assembly due to prolonged disuse.

[0056] The idle time, power-on status, cleaning trigger time, and operating mode of the aforementioned water treatment equipment control the water output from the water tank. While cleaning the filter component 20, it can also selectively flush the water outlet pipeline to ensure the cleanliness of the entire pipeline.

[0057] In this embodiment, before controlling the water outlet of the water tank to clean the filter assembly, the following steps are also included: Control the water inlet pipe to flush the filter components.

[0058] For example, when the detected inlet water TDS is greater than or equal to the preset TDS, the inlet water pipeline is first controlled to flush the filter assembly, and then the water outlet from the water tank is controlled to flush the filter assembly a second time. This improves the flushing effect.

[0059] Alternatively, when the TDS of the influent is detected to be lower than the preset TDS, and the cumulative water production time or cumulative water production volume reaches the preset water production volume, the influent pipe is first controlled to flush the filter assembly, and then the water outlet from the water tank is controlled to perform a secondary flush on the filter assembly. Since the influent TDS is lower than the preset TDS, it indicates that the pollution level of the raw water is low. Therefore, after controlling the influent pipe to flush the filter assembly, the secondary flushing step of the water outlet from the water tank can be omitted, reducing purified water consumption.

[0060] Alternatively, when the device is detected to be powered on again or in holiday mode, the water inlet pipe is first controlled to flush the filter components, and then the water outlet from the water tank is controlled to flush the filter components a second time.

[0061] In power outage or holiday mode, the water tank can be emptied to prevent bacteria from growing due to prolonged stagnation. In this case, the filter components are first flushed through the inlet pipe to ensure their cleanliness; then, water is produced, and the purified water is used to flush the filter components a second time to prevent impurities from accumulating on them and affecting subsequent water production.

[0062] In holiday mode, the cleaning step of rinsing the filter components with water from the water tank can be omitted. The filter components can be rinsed simply by controlling the water inlet pipe, eliminating the need to add water to the water tank.

[0063] In holiday mode, storing purified water in the water tank will again cause the water in the tank to stand for a long time and breed bacteria. Therefore, after rinsing the filter components with the purified water, the water tank is emptied again.

[0064] In other embodiments, during the holiday mode, the water tank may not be emptied; instead, the water in the tank is kept clean by periodically disinfecting the purified water within. This allows the purified water in the tank to be used to periodically flush the inlet and outlet pipes, maintaining the cleanliness of the water system during the holiday mode.

[0065] Alternatively, when the current time is detected as the cleaning trigger time, the water inlet pipe is first controlled to flush the filter components, and then the water outlet of the water tank is controlled to flush the filter components a second time.

[0066] Based on the cleaning trigger time, the water output from the water tank can be further controlled to flush the outlet pipe, and the flushing flow rate and flushing duration can be controlled. For example, when the cleaning trigger time is during the day, the water tank 30 is controlled to output water at a faster flow rate to quickly clean the outlet pipe of the water tank 30 for 1 minute; when the cleaning trigger time is at night, the water tank 30 is controlled to output water at a slower flow rate to slowly clean the outlet pipe of the water tank 30 for 5 minutes. This reduces the impact of nighttime flushing noise on users.

[0067] Alternatively, a preset ultra-clean mode can be used. When the water treatment equipment is detected to be in ultra-clean mode, each time the filter components are cleaned, the inlet water pipe is first controlled to flush the filter components, and then the water tank outlet is controlled to flush the filter components a second time.

[0068] Example 2 Based on Embodiment 1 above, this embodiment further improves the cleaning control method. This cleaning control method is applied to the water treatment equipment described in Embodiment 1, and the controller is used to execute the improved cleaning control method. The structure of the water treatment equipment will not be described in detail here; the implementation structure of the water treatment equipment is described in Embodiment 1.

[0069] Unlike Embodiment 1, when controlling the water output from the water tank and cleaning the filter assembly, the following steps are also included: The filter assembly's purified water outlet is connected to the first water inlet of the water tank, and the filter assembly's inlet is connected to the water outlet of the water tank, so that the filter assembly is circulated and cleaned by the water outlet of the water tank.

[0070] Specifically, refer to Figure 2 The purified water in the water tank is pumped into the filter assembly to rinse the filter assembly, and then flows back into the water tank, thus repeatedly rinsing the filter assembly.

[0071] In this way, the filter component 20 is circulated and diluted by the water outlet of the water tank, which improves the cleaning effect and reduces the waste of purified water.

[0072] Furthermore, during the circulating dilution and rinsing process, the UV sterilization component in the water tank 30 is simultaneously activated. In this way, while using purified water to circulate and dilute the filter component 20, the water returning to the water tank can also be repeatedly sterilized, thereby improving the cleaning effect.

[0073] Example 3 Based on the above embodiment 2, this embodiment further improves the water treatment equipment and cleaning control method. The cleaning control method is applied to the improved water treatment equipment, and the controller is used to execute the improved cleaning control method.

[0074] like Figure 3 As shown, the improved water treatment equipment includes an inlet pipe 10, a filter assembly 20, a water tank 30, and a control system. The inlet of the filter assembly 20 is connected to the raw water inlet of the water treatment equipment via the inlet pipe 10. The purified water outlet of the filter assembly 20 is connected to the first inlet of the water tank 30. An outlet pipe 40 is provided between the outlet of the water tank 30 and the faucet outlet of the water treatment equipment. A cleaning pipe 50 is connected between the inlet of the filter assembly 20 and the outlet of the water tank 30. The other end of the cleaning pipe 50 is connected to the inlet of the filter assembly 20 via the inlet pipe, and one end of the cleaning pipe 50 is connected to the outlet of the water tank 30 via the outlet pipe.

[0075] The faucet outlet is equipped with a switching valve 101. The inlet of the switching valve 101 is connected to the outlet pipe 40. The first outlet of the switching valve 101 is connected to the second inlet of the water tank 30. The second outlet of the switching valve 101 is used for faucet water output.

[0076] The cleaning control method in this embodiment differs from the cleaning control method described in Embodiment 2 in that, when controlling the water outlet from the water tank to clean the water outlet pipe, it further includes: The control switching valve is connected to the second inlet of the water tank, and the water outlet of the water tank is used to circulate and clean the outlet pipe.

[0077] Specifically, refer to Figure 3 The clean water in the water tank is pumped into the outlet pipe to flush the outlet pipe, and then switched back to the water tank by the switching valve. This cycle is repeated to achieve repeated flushing of the outlet pipe.

[0078] In this way, the water outlet pipe 30 is flushed by the water from the water tank, which improves the cleaning effect and reduces the waste of clean water.

[0079] Furthermore, the switching valve is located at the faucet outlet, allowing the cleaning of the water pipes to reach directly to the faucet outlet, achieving full cleaning of the pipes from the water tank to the faucet outlet, and avoiding the problem of residual water in the water pipes connected to the faucet, which can breed scale and bacteria.

[0080] In this embodiment, the first and second water inlets of the water tank 30 are different inlets. When the water tank 30 is controlled to discharge water, the filter assembly 20 and the water outlet pipe 40 can be cleaned simultaneously to improve cleaning efficiency; or, the filter assembly 20 and the water outlet pipe 40 can be cleaned separately at different times to provide a better cleaning effect.

[0081] In some other embodiments, the first and second water inlets of the water tank 30 can be the same. In this case, controlling the water tank 30 to discharge water can first clean and recirculate the filter assembly 20, and after sterilization by the UV assembly in the water tank 30, control the water tank 30 to discharge water again to clean and recirculate the water outlet pipe 40.

[0082] Furthermore, during the circulating dilution and rinsing process, the UV sterilization component in the water tank 30 is simultaneously activated. In this way, while using purified water to circulate and dilute the water outlet pipe 20, the water returning to the water tank can also be re-disinfected, thereby improving the cleaning effect.

[0083] Furthermore, a flow-through sterilization module is installed on the water outlet pipe. When controlling the water output from the water tank and cleaning the water outlet pipes, the following are also included: Control the flow-through sterilization module to start.

[0084] Specifically, during the process of circulating and rinsing the purified water in the water tank through the outlet pipe, the purified water flowing through the flow sterilization module is disinfected, and the outlet pipe is disinfected a second time.

[0085] In this way, by adding a flow-through sterilization step, impurities and bacteria flushed out of the water outlet pipe can be sterilized a second time, reducing the risk of these impurities and bacteria flowing back into the water tank and causing secondary pollution.

[0086] Example 4 Based on the above embodiment 3, this embodiment further improves the water treatment equipment and cleaning control method, and the cleaning control method is applied to the improved water treatment equipment.

[0087] like Figure 4 As shown, the improved water treatment equipment also includes: a reversing valve 102 and a high-temperature pipeline 60. The reversing valve 102 is connected to the pipeline between the switching valve 101 and the second inlet of the water tank 30. The inlet of the reversing valve 102 is connected to the first outlet of the switching valve 101, and the first outlet of the reversing valve 102 is connected to the second inlet of the water tank 30. The second outlet of the reversing valve 102 is connected to the outlet pipeline 40 through the high-temperature pipeline 60.

[0088] The cleaning control method in this embodiment differs from the cleaning control method described in Embodiment 3 in that it further includes: controlling the switching valve and the reversing valve to be connected, the reversing valve and the high-temperature pipeline to be connected, controlling the water outlet of the high-temperature pipeline, and circulating and rinsing the high-temperature pipeline and the high-temperature sterilization circuit formed by the water outlet pipeline.

[0089] Reference Figure 5 The high-temperature pipeline includes a heat storage component to store high-temperature hot water, which can be between 60℃ and 100℃. The heat storage component can be a heat tank 70. During cleaning, the water outlet from the heat storage component is controlled to flow through the water supply pipeline 80, performing high-temperature flushing and sterilization on the pipeline between the heat storage component and the switching valve, as well as the switching valve itself. The flushed water then flows back to the heat storage component through the reversing valve, creating a continuous cycle that repeatedly flushes the pipeline between the heat storage component and the switching valve, improving the cleaning effect.

[0090] Specifically, the system controls the switching valve and the reversing valve to be connected, and the reversing valve to be connected to the high-temperature pipeline, controlling the water output from the high-temperature pipeline, and circulating and flushing the high-temperature pipeline and the water outlet pipeline to form a high-temperature sterilization circuit, including: If the water treatment equipment is detected to have reached its fourth operating period, control the water output of the heat storage component and perform high-temperature flushing on the pipeline between the heat storage component and the switching valve, as well as the switching valve itself.

[0091] The above-mentioned high-temperature flushing process is cyclical. For example, the fourth run lasts for 12 hours, and every 12 hours, the water outlet of the heat storage component is controlled to perform a high-temperature flush on the pipeline between the heat storage component and the switching valve, as well as the switching valve.

[0092] In this way, during the operation cycle of the water treatment equipment, the faucet outlet can be sterilely rinsed and rinsed at high temperature, ensuring the quality of the water from the faucet, keeping the faucet outlet clean, and preventing bacteria from growing at the faucet outlet.

[0093] Furthermore, an instant heating module is installed on the water outlet pipe between the heat storage component and the switching valve. This way, when the water in the heat storage component needs heating, the system controls the water outlet of the heat storage component to heat the water, which is then stored in the heat storage component. When the heat storage component needs replenishment, the system controls the water tank outlet to heat the water to a high temperature before adding it to the heat storage component.

[0094] By setting up an instant heating module, it is convenient to add high-temperature water to the heat storage component or to reheat the water in the heat storage component.

[0095] In other embodiments, a heating unit may be provided within the heat storage component to heat and maintain the water in the heat storage component at a temperature capable of sterilization.

[0096] To facilitate understanding of pipeline control, the water treatment equipment in Example 5 will be described clearly and completely below.

[0097] like Figure 6 As shown, the water treatment equipment includes: an inlet pipe 10, a filter assembly 20, a water tank 30, a heat tank 70, a switching valve 101, and a reversing valve 102.

[0098] One end of the inlet pipe 10 is the inlet of the water treatment equipment, where a pre-filter 103 is installed to perform preliminary filtration of the raw water source. The other end of the inlet pipe 10 is connected to the inlet of the filter assembly 20. The purified water outlet of the filter assembly 20 is connected to the first inlet of the water tank 30. An outlet pipe 40 is provided between the outlet of the water tank 30 and the inlet of the switching valve 101, and a cleaning pipe 50 is provided between the outlet of the water tank 30 and the inlet pipe 10. One end of the cleaning pipe 50 is connected to the inlet of the filter assembly 20 through the inlet pipe 10, and the other end is connected to the outlet of the water tank 30 through the outlet pipe 40. The first outlet of the switching valve 101 is connected to the inlet of the reversing valve 102, and the second outlet of the switching valve 101 is used for water supply. The first outlet of the reversing valve 102 is connected to the second inlet of the water tank 30, and the second outlet of the reversing valve 102 is connected to the inlet of the hot water tank 70. The outlet of the hot water tank 70 is connected to the outlet pipe 40 through the water supply pipe 80.

[0099] A first solenoid valve 104 and a first pump body 105 are sequentially installed on the water inlet pipe 10. The first solenoid valve 104 is located between the pre-filter element 103 and the cleaning pipe 50, and the first pump body 105 is located between the cleaning pipe 50 and the water inlet of the filter assembly 20. The first pump body 105 is a booster pump.

[0100] A second solenoid valve 106 may be installed on the cleaning pipeline 50. A third solenoid valve 107 may be installed on the pipeline between the clean water outlet of the filter assembly 20 and the first water inlet of the water tank 30, and a wastewater valve 108 may be installed on the wastewater outlet of the filter assembly 20. A second pump body 109 and a post-filter element 110 are sequentially installed on the water outlet pipeline 40 of the water tank 30. The second pump body 109 is a gear pump.

[0101] A third pump body 111 may be installed on the water supply pipeline 80. The third pump body is an impeller pump.

[0102] Each of the water outlet pipe 40, the cleaning pipe 50, and the water supply pipe 80 is equipped with at least one check valve to prevent backflow. Specifically, the inlet of the first check valve 112 on the water outlet pipe 40 is connected to the outlet of the water tank 30, the inlet of the second check valve 113 on the cleaning pipe 50 is connected to the outlet of the water tank 30, and the inlet of the third check valve 114 on the water supply pipe 80 is connected to the outlet of the hot water tank 70.

[0103] The water inlet pipe is controlled to clean the filter assembly. Specifically, the first solenoid valve 104 is turned on, the wastewater valve 108 is turned on, the first pump body 105 is run, the first pump body 105 draws raw water from the water treatment equipment inlet, and after preliminary filtration by the pre-filter 103, it is pressurized and pumped into the filter assembly to flush the filter assembly until the raw water flushing of the filter assembly is completed.

[0104] The water tank outlet is controlled to clean the filter assembly. Specifically, the second solenoid valve 106 and the third solenoid valve 107 are turned on, the first pump body 105 is started, the first pump body 105 draws clean water from the water tank 30, pressurizes it and pumps it into the filter assembly to rinse the filter assembly, and then returns it to the water tank 30 through the third solenoid valve 107. This cycle is repeated until the sterile rinsing of the filter assembly is completed.

[0105] The water outlet of the water tank is controlled to clean the outlet pipeline. Specifically, the switching valve and the reversing valve are connected, and the reversing valve is connected to the water tank. The second pump body is running. The second pump body 109 draws clean water from the water tank 30 and pumps it into the outlet pipeline. The clean water rinses the outlet pipeline, the post-filter 110, and the switching valve 101 before returning to the water tank. This cycle is repeated until the sterile rinsing of the outlet pipeline, the post-filter 110, and the switching valve 101 is completed.

[0106] The high-temperature sterilization circuit formed by the high-temperature pipeline and the outlet water pipeline is circulated and flushed. Specifically, the switching valve and the reversing valve are connected, the reversing valve and the high-temperature pipeline are connected, the third pump body is running, the third pump body 111 draws high-temperature water from the hot tank 70 and pumps it into the water supply pipeline 80. The high-temperature water flows back to the hot tank 70 after passing through the outlet water pipeline between the water supply pipeline 80 and the switching valve 101, the switching valve 101, and the reversing valve 102. This cycle is repeated until the high-temperature flushing of the pipeline between the hot tank and the switching valve and the switching valve is completed.
