Description

Technical Field

[0001] This utility model relates to the field of household water use, and in particular to a sterile pure water tank structure and a household central pure water system. Background Technology

[0002] Domestic water refers to the water needed for daily life, including household water use such as drinking, washing, and watering plants. Whether domestic water is hygienic, safe, and of acceptable quality is directly related to everyone's health. As people's quality of life improves, the requirements for the quality of domestic water are becoming increasingly stringent. Typically, terminal filtration and purification components are installed at the water outlet of a household to improve the purity of drinking water; or a central water purification and softening system is used throughout the house to improve the overall quality of water used for washing, laundry, underfloor heating, etc.

[0003] However, existing methods of improving water quality by adding localized filtration components are limited in their daily water supply, often requiring residents to fetch water from designated points, causing inconvenience. Furthermore, their purification capabilities are limited, only providing drinking water purification and failing to address the purification needs of other water used for washing. While whole-house central water purification and softening systems offer insufficient filtration precision, leaving impurities in the water, and central softening can increase sodium ion levels, they are not ideal for domestic use despite improving water quality. Therefore, those skilled in the art have provided a sterile pure water tank structure and a household central pure water system to address the problems mentioned in the background. This system technically allows every water point in the family to receive drinking water of the same quality as localized filtration, while removing impurities that central purification systems cannot handle and resolving the issue of increased sodium ions in central softening.

[0014] As a further technical solution of this utility model: the water inlet of the pure water purifier is raw water, which can be tap water pipe connected to it; or it can be well water or other water sources, which are connected to the water inlet of the pure water purifier through a pipe.

[0015] As a further technical solution of this utility model: the tailwater tank is provided with a tailwater pipe connected to the tailwater discharge end of the pure water purifier; the tailwater tank is provided with a raw water pipe connected to the raw water source; and the tailwater outlet of the tailwater tank has a pipeline leading to the tailwater pump, the outlet end of the tailwater pump is provided with a tailwater pipe, and the tailwater pipe is provided with at least one set of tailwater nodes along its pipeline direction.

[0016] The return water inlet 6 is connected to the return water pipe 20, which provides a return water pipeline for the whole house pure water pipe 19. The water stored in the whole house pure water pipe 19 is returned to the sterile pure water tank 1 for sterilization through the return water pipe 20 and then circulated back into the whole house pure water pipe 19.

[0017] The pure water overflow outlet 5 is connected to the drain pipe. The pure water overflow outlet 5 is higher than the pure water inlet 2. The pure water inlet 2 is higher than the purified water inlet 3. The purified water inlet 3 is higher than the pure water outlet 4. The pure water outlet 4 is connected to the whole house pure water water point.

[0018] Furthermore, it includes a raw water pipe 16, which is connected to the central pure water machine 15 and the tailwater tank 9 respectively, wherein:

[0019] The equipment's raw water pipe 16 delivers daily water, such as tap water or well water, to the central pure water machine 15. Utilizing its internal pre-membrane purification filter and reverse osmosis membrane, the tap water undergoes reverse osmosis purification to obtain purified water, pure water, and wastewater. Pure water is delivered to the sterile pure water tank 1 via the pure water pipe 17 connected to the pure water inlet 2. One path of purified water enters the sterile pure water tank 1 via the pure water pipe 18 connected to the pure water inlet 3, while the other path enters the whole-house water purification pipe 22. Wastewater... Water enters the tailwater tank 9 through the tailwater pipe 23. The sterile pure water tank 1 is connected to the pure water pump 21 through the pure water outlet 4, and the pure water is delivered to each pure water point in the whole house through the whole house pure water pipe 19. The end of the pure water pipe is connected to the return water pipe 20. The pure water flows back to the sterile pure water tank 1 through the return water port 6. After being sterilized by the ultraviolet germicidal lamp 7 in the sterile pure water tank 1 and the antibacterial silver ion material of the tank body, it can then enter the whole house pure water pipe 19 for circulation through the pure water outlet 4.

[0020] The equipment's raw water pipe 16 delivers daily water, such as tap water or well water, to the raw water inlet 12 via the raw water pipe (24) of the water tank and then to the tailwater tank 9. The tailwater tank 9 is connected to the tailwater pump 26 via the tailwater outlet 13 and the tailwater is delivered to the tailwater water point of the whole house via the whole house tailwater pipe 25.

[0021] The tailwater tank 9 is equipped with a tailwater inlet 10, a tailwater overflow outlet 11, a raw water inlet 12, a tailwater outlet 13, and a tailwater tank level control valve 14.

[0024] This utility model provides a sterile pure water tank structure and a household central pure water system, which has the following advantages compared with the prior art:

[0025] 1. This design is based on the different purification functions of the pure water purifier in the central pure water system. It generates pure water and clean water in two states and delivers them to the sterile pure water tank for later use. The domestic water undergoes a second sterilization process under the sterile pure water tank containing silver ion antibacterial material and ultraviolet germicidal lamp, forming pure domestic water. This solves the problem of domestic water purification from the source and provides whole-house pure water supply for domestic water use. It not only provides more comprehensive purification of domestic water, but also realizes the whole-house water purification needs of domestic water use, making daily water use more convenient.

[0026] 2. In this design, when supplying water to the home, the daily demand for purified water is relatively large and usually spreads throughout the entire room. Therefore, when the purified water in the room has not been used for a long time, the combination of a return water pump, a return water pipe, and a sterile purified water tank can be used to return and pump the purified water that has not been used for a long time in the indoor pipes. The water is then pumped back into the sterile purified water tank through the return pipe for a second sterilization and purification process, so as to provide clean water in real time.

[0027] 3. The purified residual wastewater of this design can be collected into the tailwater tank and used for daily household needs such as watering flowers and plants, mopping floors, and raising fish, thereby improving the utilization of domestic water and saving water resources.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-7 This utility model provides a sterile pure water tank structure and a technical solution for a household central pure water system.

[0038] On the one hand, this utility model provides a sterile pure water tank structure; please refer to [link / reference]. Figures 1-3 This includes a sterile pure water tank 1. Inside the sterile pure water tank 1, there are, in sequence, a pure water inlet 2, a clean water inlet 3, a pure water outlet 4, a pure water overflow outlet 5, a return water outlet 6, an ultraviolet sterilization lamp 7, and a clean water tank level control valve 8. Specifically:

[0039] The pure water inlet 2 is equipped with a purified water tank level control valve 8. When the water level is lower than that of the pure water inlet 2, pure water is added. When the water level is lower than that of the purified water inlet 3, the purified water inlet 3 is opened through the purified water tank level control valve 8 to add purified water, preventing insufficient water in the sterile pure water tank 1 from affecting the user's water supply. Furthermore, depending on the technical characteristics of different purified water tank level control valves 8, the pure water inlet 2 and the purified water inlet 3 can share one purified water tank level control valve 8, or each inlet can use its own separate purified water tank level control valve 8, ensuring the sterile pure water tank 1 can be used to its fullest potential. It can be filled with pure water. The pure water inlet 2 is located at the top of the water tank, and the purified water inlet 3 can be located at about one-third or one-quarter of the height from the bottom of the sterile pure water tank 1, below the waist. This allows for emergency water replenishment when the pure water in the sterile pure water tank 1 is insufficient. At the same time, the purified water is shut off when the water level exceeds the purified water inlet 3. Using a more intelligent water level control component, the vertical position of the pure water inlet 2 and the purified water inlet 3 does not need to be considered. Its design principle is to minimize the proportion of purified water in the sterile pure water tank 1 while meeting the emergency water replenishment requirements.

[0040] Furthermore, the entire body of the sterile pure water tank 1 that comes into contact with pure water is made of antibacterial materials containing silver ions. This process further sterilizes the purified water by allowing silver ions to penetrate the cells of bacteria and viruses and bind to their proteases, thereby deactivating and killing them and improving the purity of the domestic water supply.

[0041] In addition, the sterile pure water tank 1 is equipped with a built-in ultraviolet germicidal lamp 7, which irradiates and sterilizes the entire water body inside the tank. Because the lifespan of the ultraviolet germicidal lamp 7 is much shorter than the lifespan of the sterile pure water tank 1, the ultraviolet germicidal lamp 7 is designed to be easily disassembled and replaced to ensure that the water quality is clean and sterile, providing users with safe and healthy water.

[0042] Furthermore, the sterile pure water tank 1 has a pure water overflow port 5. This port is used to prevent water from overflowing the tank in a disorderly manner when the water level control valve 8 of the pure water inlet 2 and the pure water inlet 3 fails. The overflow port can be connected to the drain to guide the overflowing water away, reducing the risk of water overflow. If a fully enclosed tank is used, this pure water overflow port 5 is not required. If a non-enclosed tank is used with the pure water overflow port 5, the position of the pure water overflow port 5 can be higher than the pure water inlet 2 so that the pure water will not be lost for no reason.

[0043] As a further embodiment, the sterile pure water tank 1 is equipped with a return water inlet 6 connected to the whole-house pure water pipeline. A pure water pump 21 is located outside the pure water outlet 4. The inlet of the pure water pump 21 is connected to the pure water outlet 4 of the sterile pure water tank 1, supplying pure water into the whole-house pure water pipeline 19 to various water points. A return water pipe 20 branches off from the end of the whole-house pure water pipeline 19 and connects to the return water inlet 6 on the sterile pure water tank 1. The pure water flows back through the return water pipe 20 from the end of the whole-house pure water pipeline 19 into the return water inlet 6 and then into the sterile pure water tank 1. The ultraviolet germicidal lamp 7 and its silver ion antibacterial material housing sterilize the water again. The purified water is then sent back to the whole-house purified water pipe 19 through the purified water outlet 4 and the purified water pump 21, keeping the water in a flowing and sterile state. The connection between the return pipe 20 and the return outlet 6 can be equipped with a control valve. The return time and return speed can be controlled by opening or closing the control valve. Opening the return outlet 6 and the return pipe 20 will further ensure the real-time cleanliness of the indoor purified water. The return outlet can be designed to be lower than the full water level of the purified water tank, which can eliminate the water flow noise of the return water entering the water tank.

[0044] It should be noted that due to the large demand for indoor purified water, including daily washing, showering, and kitchen water use, there are many purified water pipes and a large amount of purified water retention. By installing a return pipe on the purified water pipe, the purified water that has not been used for a long time can be returned to provide users with purified water in real time. Users can also choose whether to need to return water. If no return water is needed, the return water inlet 6 can be closed and no return water pipe is designed, which will not affect the normal use of the whole house pure water system.

[0045] On the other hand, this utility model provides a household central purified water system; please refer to [link / reference]. Figures 3-7 , Figure 3 This is a complete household central purified water system. Daily household water, such as tap water or well water, is delivered to the central purified water machine 15 via the raw water pipe 16. Utilizing its internal pre-membrane purification filter and reverse osmosis membrane, the tap water undergoes reverse osmosis purification to obtain purified water, pure water, and wastewater. The pure water is delivered to the sterile purified water tank 1 via the pure water pipe 17 connected to the pure water inlet 2. One path of the purified water enters the sterile purified water tank 1 via the purified water pipe 18 connected to the purified water inlet 3, serving as a supplementary water source when pure water is insufficient. The other path of the purified water enters... The whole-house water purification pipe 22 leads to the drinking water outlet where people prefer to drink water that retains minerals, or to the water outlet with high water consumption, such as when washing a car. The sterile pure water tank 1 is connected to the pure water pump 21 through the pure water outlet 4 and delivers pure water to all pure water points in the whole house through the whole-house pure water pipe 19. The pure water pipe branches off to the return water pipe 20 at the end. The pure water enters the sterile pure water tank 1 through the return water outlet 6. After being sterilized by the ultraviolet germicidal lamp 7 in the sterile pure water tank 1 and the antibacterial silver ion material of the tank body, it can then enter the whole-house pure water pipe 19 through the pure water outlet 4 for circulation.

[0046] The wastewater enters the wastewater tank 9 through the wastewater inlet 10 via the wastewater pipe 23. It is then connected to the wastewater pump 26 through the wastewater outlet 13 and leads to the whole house wastewater pipe 25, which is used for irrigation, toilet flushing, and other water-use points where water quality requirements are not high. The raw water pipe 16 of the equipment is also connected to the raw water inlet 12 and enters the wastewater tank 9 as a supplementary water source when the wastewater is insufficient.

[0047] In addition to the above, if there is insufficient installation space, or depending on installation conditions or user requirements, the tailwater system can be removed without affecting the pure water supply of the whole-house pure water system, forming... Figure 4 The system is functioning normally.

[0048] Furthermore, if the whole-house purified water pipes are short, or if water usage is frequent and the system always maintains a fresh water supply, or depending on installation conditions or user requirements, the return water system can be removed without affecting the purified water supply of the whole-house purified water system, thus forming... Figure 5 The system is functioning normally.

[0049] Meanwhile, if the central pure water machine 15 in this system has a high water production capacity, or the water consumption at the downstream water points is not large, or depending on the installation conditions or user requirements, the purified water can be removed and supplemented to the sterile pure water tank 1 without affecting the pure water supply of the whole house pure water system, thus forming... Figure 6 The system is functioning normally.

[0050] Furthermore, if the user has no need for drinking mineral water, or no need for purified water access points, or depending on the installation conditions or user requirements, the whole-house water purification pipe 22 can be removed without affecting the purified water supply of the whole-house pure water system, thus forming... Figure 7 The system is functioning normally.

[0051] The above systems can be integrated into the complete machine as finished products, or they can be assembled into systems at the installation site as components.

[0052] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
