[0029] Water purifiers have become an essential device in modern families. However, traditional water purifiers face many challenges during long-term use. Components such as pipes and solenoid valves inside the water purifier are prone to bacterial growth and scale formation after long-term use, which not only affects water quality safety but may also reduce the filtration efficiency of the device. Most water purifiers on the market currently lack an effective self-cleaning function. Users need to manually disassemble each component for cleaning, which is not only cumbersome and time-consuming but also requires professional knowledge, making it difficult for ordinary users to clean thoroughly. In addition, frequent manual intervention may introduce new pollution, which is counterproductive.
[0030] Referring to Figure 1 , this application provides an integrated system for water filtration and cleaning of a water purifier, including a water inlet pipe 100, a drain pipe 200, a filtration device 300, a pure water tank 400, a delivery pump 110, a water inlet solenoid valve 120, and a reversing valve 500.
[0031] The filtration device 300 is connected to the water inlet pipe 100 through a delivery pipe 600. The concentrated water outlet of the filtration device 300 is connected to the drain pipe 200 through a concentrated water pipe 332. A concentrated water solenoid valve 210 is provided on the drain pipe 200. The pure water tank 400 is connected to the pure water outlet of the filtration device 300 through a pure water pipe 331. The delivery pump 110 is arranged on the water inlet pipe 100. The water inlet solenoid valve 120 is arranged on the water inlet pipe 100. The reversing valve 500 has a water inlet and at least two water outlets. The water inlet is connected to the water inlet pipe 100. One of the water outlets is connected to the delivery pipe 600, and the other water outlet is connected to the drain pipe 200 through a connecting pipe 510.
[0032] When filtering water, the delivery pump 110 pumps tap water into the water inlet pipe 100. The reversing valve 500 connects the water inlet pipe 100 and the delivery pipe 600. The tap water enters the filtration device 300 after passing through the reversing valve 500 and the delivery pipe 600. The filtered pure water enters the pure water tank 400, and the filtered concentrated water is discharged from the drain pipe 200 after passing through the concentrated water pipe 331 and the concentrated water solenoid valve 210.
[0033] When cleaning the pipeline, the reversing valve 500 connects the water inlet pipe 100 and the connecting pipe 510. The delivery pump 110 pumps the cleaning liquid into the water inlet pipe 100. The cleaning liquid is discharged from the drain pipe 200 after passing through the reversing valve 500, the connecting pipe 510, and the concentrated water solenoid valve 210, thereby cleaning the dirt inside the water inlet pipe 100, the drain pipe 200, the connecting pipe 510, the water inlet solenoid valve 120, the delivery pump 110, the reversing valve 500, and the concentrated water solenoid valve 210. This system integrates water filtration and cleaning. When filtering water for a long time, the cleaning function can be activated to self-clean the corresponding components inside the water purifier without the need to manually disassemble each component for cleaning.
[0034] In some embodiments, the integrated water purification and cleaning system of the water purifier further includes a water addition tank 700. A water outlet pipe 710 and a water return pipe 720 are provided on the water addition tank 700. Ball valves are provided on both the water outlet pipe 710 and the water return pipe 720. The water outlet pipe 710 is communicated with the water inlet pipe 100, and the water return pipe 720 is communicated with the drain pipe 200.
[0035] During use, the pipe orifices of the water inlet pipe 100 and the drain pipe 200 are blocked. The water addition tank 700 serves as a water source. When filtering water, the delivery pump 110 pumps the water in the water addition tank 700 into the water inlet pipe 100. The reversing valve 500 connects the water inlet pipe 100 and the delivery pipe 600. The tap water enters the filtering device 300 after passing through the reversing valve 500 and the delivery pipe 600. The filtered pure water enters the pure water tank 400. The filtered concentrated water enters the water addition tank 700 after passing through the concentrated water pipe 332, the concentrated water solenoid valve 210, the drain pipe 200 and the water return pipe 720.
[0036] When cleaning the pipeline, the cleaning liquid, such as citric acid solution, is replaced in the water addition tank 700. The reversing valve 500 connects the water inlet pipe 100 and the connecting pipe 510. The delivery pump 110 pumps the cleaning liquid in the water addition tank 700 into the water inlet pipe 100. The cleaning liquid enters the water addition tank 700 after passing through the reversing valve 500, the connecting pipe 510, the concentrated water solenoid valve 210, the drain pipe 200 and the water return pipe 720, thereby cleaning the dirt in the connecting pipe 510, the concentrated water solenoid valve 210, the drain pipe 200, the water return pipe 720, the delivery pump 110, the reversing valve 500 and the water inlet pipe 100.
[0037] In some embodiments, a check valve 333 is installed on the concentrated water pipe 332. The check valve 333 is located between the concentrated water solenoid valve 210 and the filtering device 300. The check valve 333 prevents the cleaning liquid from flowing back into the filtering device 300 from the concentrated water pipe 332 during the cleaning process.
[0038] In some embodiments, the reversing valve 500 is a one-inlet two-outlet solenoid valve. It is convenient to realize automatic control.
[0039] In some embodiments, a source water TDS probe 800 is installed on the water inlet pipe 100. The source water TDS probe 800 is located between the delivery pump 110 and the reversing valve 500. The cleanliness of the source water is detected by the source water TDS probe 800.
[0040] In some embodiments, the delivery pump 110 is a self-priming booster pump. The self-priming booster pump can automatically discharge the air in the pump body and the suction pipe, and there is no need for additional manual priming after startup, which is convenient to operate and has good applicability in this application.
[0041] In some embodiments, the filtering device 300 includes a primary filter element 310, a secondary filter element 320, and a tertiary filter element 330 connected in sequence. Activated carbon is provided inside the primary filter element 310, carbon rods are provided inside the secondary filter element 320, and reverse osmosis filter membranes are provided inside the tertiary filter element 330.
[0042] Furthermore, PP cotton is provided inside both the primary filter element 310 and the secondary filter element 320.
[0043] Specifically, in the primary filter element 310, the PP cotton is located above the activated carbon. After tap water enters the primary filter element 310, it first passes through the filtration of the PP cotton and then through the filtration of the activated carbon. In the secondary filter element 320, the PP cotton is located below the carbon rods. After the water flowing out of the primary filter element 310 enters the secondary filter element 320, it first passes through the filtration of the carbon rods and then through the filtration of the PP cotton.
