Description

Technical Field

[0001] This isolated 0-year-old water membrane protection technology belongs to the invention related to RO reverse osmosis water purification equipment. This invention not only realizes the technical effect of drinkable water as soon as the machine is turned on and effectively protects the RO membrane, but also makes the water production system of the pure water machine and the 0-year-old water membrane protection system both related and complete and independent of each other: even if the 0-year-old water membrane protection system fails, it will not affect the normal water production and use of the original system of the pure water machine. On the contrary, the normal operation of the 0-year-old water membrane protection system will not be affected when the pure water machine is not equipped with a pressure tank or the pressure tank does not store enough water, thereby making the overall operation of the pure water machine more stable and reliable, greatly improving the durability, economy and practicality of the pure water machine. Background Art

[0002] After the water purifier has been shut down for some time, the first cup of water produced when it is turned on again cannot be drunk due to the high TDS value and bad taste. In addition, after the water purifier stops making water, the RO membrane is soaked in raw water for a long time, and the RO membrane is easily blocked, resulting in less water output or no water output. This increases our core replacement frequency and maintenance costs, and has become another problem and obstacle to the popularization of water purifiers in households.

[0003] However, the existing technology not only has the problems of interdependence between the pure water machine water production system and the 0-year-old water protection film system, unstable operation, and high operation and maintenance costs, but also cannot be applied to the more advanced design and manufacturing requirements of different models in the entire pure water machine industry, resulting in the 0-year-old water protection film technology cannot be well applied, so that the pure water machine that every household needs has not yet been truly popularized.

[0004] Therefore, a universal, stable, low-maintenance cost, good effect, and high universality 0-aging water film protection technology is urgently needed to be developed. Summary of the invention

[0005] In order to change the problem that the first cup of water after the existing pure water machine is unusable after startup, and the RO membrane is easily blocked after being immersed in raw water for a long time after shutdown, so that people can use cleaner and more affordable pure water and make pure water machines truly popular, after long-term experiments and practical verification, we finally successfully invented a universal, stable, lower-cost and better-effective isolated 0-stale water protective membrane technology ( Figure 1): The biggest feature of the present invention is that the 0 stagnant water protection film system is associated and isolated from the original system of the pure water machine. The control circuits of the water production system and the 0 stagnant water protection film system of the pure water machine are completely isolated through the isolation relay (2) and the isolation relay (3). Then, through the cooperation of the two groups of waterway isolation components, namely the isolation solenoid valve (4), the isolation check valve (5) and the isolation solenoid valve (7), the isolation check valve (8), the waterways of the water production system and the 0 stagnant water protection film system of the pure water machine are isolated, so that the water production system and the 0 stagnant water protection film system of the pure water machine are in a completely isolated but connected associated state: that is, the 0 stagnant water protection film system is in an isolated state from the water production system of the pure water machine during operation and does not need to rely on the cooperation of the water production system of the pure water machine; on the contrary, even if the 0 stagnant water protection film system ( Figure 1 red dotted line frame) fails, it will not affect the normal operation of the pure water system of the pure water machine. This is the difference and advantage of the present invention from other 0 stagnant water technologies.

[0006] Experiments have proved that the Figure 1 shown isolated 0 stagnant water protection film technology can be applied to the modification and production of all current pure water machines, and has many advantages such as stronger versatility, higher stability and greater application value.

[0007] The birth and application of the present invention can improve the phenomenon that the TDS value of the first glass of water is too high after the pure water machine is turned on, truly achieve all-time freshness, and the water production effect that the water can be drunk immediately after it comes out; at the same time, it also ensures the self-cleaning of the RO membrane (19), protects it from fouling and blockage, effectively extends the service life of the RO membrane, further reduces our water use cost, and thus accelerates the popularization process of water purifiers, and quickly realizes the beautiful wish that everyone can use healthy good water. Brief Description of the Drawings

[0008] Figure 1 is a schematic diagram of the isolated 0 stagnant water protection film technology system. The system components ( Figure 1 inside the red dotted line frame) include: 0 stagnant water control module (1), booster pump isolation relay (2), waste water solenoid valve isolation relay (3), isolation solenoid valve (4), isolation check valve (5), three-way joint (6), isolation solenoid valve (7), isolation check valve (8), three-way joint (9), isolation water storage bottle (10), one-way air inlet valve (11), air filter (12).

[0009] Figure 2 is a partial enlarged view of the Figure 1 red dotted line frame in the specification appendix.

[0010] Functions of each component of the system: 1) 0.02 water control module (1): a special device for automatically controlling the 0.02 water protection system by cleverly connecting the 0.02 water protection system with the electric control system of the pure water machine, and setting the two time parameter values ​​A and B according to the application scenario and model of the pure water machine; its working mode is: it does not act when there is a trigger signal, it is attracted after the signal disappears and lasts for A time, and then disconnected after a delay of B time; [Special note: the A time value here is set according to the use scenario of the pure water machine, because in some occasions or time periods (such as family cooking time or peak hours of commercial applications) water needs to be used frequently, and the pure water machine will naturally be frequently turned on and off, but our RO membrane does not need to be frequently injected with protective pure water in a short period of time. Therefore, this A time is set to monitor the interval time of each water use. Only when the set A time value is met, the 0-year-old water membrane protection system will be started, thereby reducing unnecessary startup frequency and avoiding waste (of course, the A time can also be set to a very short time or 0 value, and the 0-year-old water membrane protection system will be started immediately after each start and stop of the pure water machine. The biggest advantage of this mode is that it has an excellent protective effect on the RO membrane); its B time value is determined according to different models of pure water machines. The specific parameters are based on the actual time for the protection pure water to fill the RO membrane of the model (for example, the 0-year-old water membrane protection system can fill the RO membrane of a 400G pure water machine in 3 seconds, so the B time value of the 0-year-old water control module can be set to 3 seconds, and it will not change once set)]; 2) Booster pump isolation relay (2): completely isolates and automatically switches the two booster pump control terminals from the pure water machine original system and the 0-year water film system, so that the booster pump is controlled by either the pure water machine water system or the 0-year water film system; 3) Wastewater valve solenoid valve isolation relay (3): completely isolates and automatically switches the two wastewater valve solenoid valve control ends from the pure water machine original system and the 0-year water film protection system, so that the wastewater valve solenoid valve is controlled by either the pure water machine water system or the 0-year water film protection system; 4) Isolation solenoid valve (4): an automatic switch that controls the connection or disconnection of the water path between the pure water machine water system and the 0.5% water membrane protection system; 5) Isolation check valve (5): only allows water from the pure water machine water system to flow to the 0-year water film protection system. It is combined with the isolation solenoid valve (4) to form a one-way solenoid switch to achieve automatic control of isolation or one-way conduction between the pure water machine water system and the 0-year water film protection system; 6) Three-way connector (6): It is used to connect the water supply system of the pure water machine and isolate the water storage bottle (10) and the water supply side of the booster pump (18); 7) Isolation solenoid valve (7): an automatic actuator that controls the connection or disconnection between the isolation water storage bottle (10) and the water path on the water inlet side of the booster pump; 8) Isolation one-way valve (8): only allows the film-protected pure water in the isolation water storage bottle (10) to flow to the water inlet of the booster pump (18), and is combined with the isolation solenoid valve (7) to form a one-way solenoid switch to achieve automatic control of isolation or one-way conduction between the 0-year water film protection system and the pure water machine water system; 9) Tee connector (9): Installed on the water inlet side of the booster pump (18) to achieve selective water supply to the booster pump, either from the pure water machine water supply system (blue arrow icon) or from the 0.5% water protection membrane system (green arrow icon); 10) Isolation water storage bottle (10): It is a special water storage container for the 0-year water protection film system. When the 0-year water protection film system is in operation, it is completely isolated from the pure water machine water system. Regardless of whether the pure water machine water system has water storage or not, the 0-year water protection film system can operate normally; 11) One-way air inlet valve (11): When the isolation water storage bottle (10) is under negative pressure, the outside air flows into the isolation water storage bottle (10) through the one-way air inlet valve, so that the protective film pure water in the bottle can be smoothly pumped into the RO membrane (19) by the booster pump (18). When the isolation water storage bottle (10) is storing water, the one-way air inlet valve prevents the air in the bottle from flowing out, thereby playing the role of increasing and maintaining pressure; 12) Air filter (12): Since the isolated water storage bottle (10) stores pure water with protective film, no unclean air can flow in to contaminate the pure water with protective film. Therefore, this air filter device is used to filter the intake air before it flows into the isolated water storage bottle (10) through the one-way intake valve (11). DETAILED DESCRIPTION

[0011] Regardless of the specifications and size of the water purifier, the standard booster pump (18) must be a self-priming booster pump with no water pressure requirement.

[0012] Power supply: Share the 24V power supply (15) of the water purifier, no need to purchase separately.

[0013] Signal source: The control end (14) of the pure water machine water inlet solenoid valve (13) is used as the trigger signal source of the 0-chen water control module (1), so that the 0-chen water control module (1) outputs different trigger signals according to the opening and closing of the water inlet solenoid valve (13), so that the 0-chen water control module (1) outputs the control voltage of the isolation relays (2) and (3) according to the established parameters, controls the start and stop of the booster pump isolation relay (2) and the waste water solenoid valve isolation relay (3), thereby realizing the switching of the start source of the booster pump (18) and the waste water solenoid valve (20), either starting due to the pure water machine making water, or starting due to the operation of the 0-chen water film protection system, otherwise it is completely stopped.

[0014] like Figure 1 As shown: 1) Connect all relevant components and pipelines of the isolated 0-stage water film protection system; 2) Connect the input terminal of the 0-stage water control module (1) to the local power supply (15) and the normally open terminal of the booster pump isolation relay (2); 3) The booster pump control terminal (16) of the pure water machine is connected to the normally closed terminal of the booster pump isolation relay (2), and the booster pump (18) is connected to the common terminal of the booster pump isolation relay (2); 4) Connect the output end of the 0 stale water control module (1) to the isolation solenoid valve (7), the control end of the booster pump isolation relay (2) and the control end and normally open end of the wastewater solenoid valve isolation relay (3); 5) Connect the control terminal (17) of the wastewater solenoid valve of the water purifier to the normally closed terminal of the wastewater solenoid valve isolation relay (3), and connect the wastewater solenoid valve (20) to the common terminal of the wastewater solenoid valve isolation relay (3); 6) Connect the water inlet solenoid valve control line (14) to the water inlet solenoid valve (13) and at the same time connect it to the signal input terminal of the 0-stage water control module (1) and the isolation solenoid valve (4).

[0015] When the water purifier starts to produce water, the water inlet solenoid valve (13) is started and a trigger signal (14) is input to the 0-year water control module (1). At this time, the 0-year water control module (1) does not operate and the water purifier system is in an independent water production operation state.

[0016] When the pure water machine stops producing water after the water is full, the water inlet solenoid valve (13) is closed. At this time, the trigger signal (14) disappears and the A time of the zero-aged water control module (1) is triggered to start counting down. When the time is up, the control signal of the isolation relay is output to control the booster pump isolation relay (2) and the waste water solenoid valve isolation relay (3) to start, and the booster pump (18) and the waste water solenoid valve (20) are switched to the zero-aged water membrane protection system control, and the pure water machine water state enters the zero-aged water membrane protection system operation state. At the same time, the isolation solenoid valve (4) is closed and the isolation solenoid valve (7) is opened. At this time, the booster pump (18) injects protective pure water into the RO membrane (19).

[0017] When the protective pure water is filled (that is, the B time set for filling the protective pure water is reached), the 0-stage water control module (1) controls the booster pump isolation relay (2) and the waste water solenoid valve isolation relay (3) to switch to the pure water machine standby state and close the isolation solenoid valve (7). At this time, no matter how long the pure water machine is shut down, the RO membrane (19) is always immersed in clean pure water and will not be blocked by dirt.

[0018] When the pressure of the water purifier is reduced due to water use, the high pressure switch (21) is activated, and when the water purifier starts to produce water again, the above 0% water protection membrane system operation process will be repeated, so that the water discharged from the water purifier is drinkable, while protecting the isolated 0% water protection membrane technology of the RO membrane.
