DETAILED DESCRIPTION

[0026] In order to make the objects, technical solutions and advantages of the present application clearer, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0027] In the related art, the pipeline machine usually has a water tank for storing a proper amount of pure water. However, the pipeline machine with the water tank is prone to have a large size, which is not conducive to the miniaturization design of the pipeline machine. In addition, bacteria are likely to breed in the water tank for a long time, which leads to the general water quality of the pipeline machine.

[0028] To solve the above problems, the embodiments of the present application provide a pure drinking system, which is a comprehensive system integrating water purification and convenient drinking water functions. The pure drinking system can be applied to places such as homes, offices, schools, and hospitals, which are not specifically limited by the embodiments of the present application.

[0029] Please refer to Figure 1 , the pure drinking system includes a water purifier 3 and a water tank-free pipeline machine 2. The water purifier 3 has a raw water inlet 31 for connecting tap water, and the water purifier 3 is used for deep filtration and purification treatment of tap water, so that the water quality of the water source meets the standard of safe drinking or meets the specific use requirements. The working principle of the water purifier 3 usually includes pre-filtering, precision filtering, and post-treatment, etc. The pre-filtering mainly uses a filter screen to filter out large particles of impurities in tap water. The precision filtering uses more advanced filtering technology to remove small molecules, harmful substances, etc. in tap water. The post-treatment may include activated carbon adsorption, etc. to improve the taste of water. The water purifier 3 also has a pure water outlet 32, and the water tank-free pipeline machine 2 is in communication with the pure water outlet 32, so that the pure water purified by the water purifier 3 can flow from the pure water outlet 32 to the water tank-free pipeline machine 2, and the water tank-free pipeline machine 2 is used for instant heating or refrigeration of the purified pure water, so as to facilitate users to accurately obtain drinking water and meet different drinking water temperature requirements of users.

[0030] Please continue to refer to Figure 1In some embodiments, the direct drinking system can further comprise a faucet 4, which can be directly connected with the water purifier 3, so that the faucet 4 can directly flow out the purified pure water from the water purifier 3. Further, considering that the water pressure in the water supply pipeline for providing tap water to the water purifier 3 can change due to various factors (such as water supply peak, pipeline maintenance, etc.), a pressure reducing valve is usually configured before the raw water inlet 31 of the water purifier 3, which not only stabilizes the water pressure in the water supply pipeline and reduces the water pressure entering the water purifier 3 in advance, but also avoids physical damage to the water purifier 3 due to excessive water pressure. In order to simultaneously distribute the purified pure water to the tankless pipeline machine 2 and the faucet 4 and improve water utilization efficiency, a flow divider is usually configured at the rear end of the pure water outlet 32 of the water purifier 3. The water inlet end of the tankless pipeline machine 2 and the water inlet of the faucet 4 are both in communication with the flow divider. When the user needs to take temperature-adjusted direct drinking water, such as 5℃-15℃ ice water in hot summer, 40℃-50℃ warm water for washing milk powder, or 90℃-99℃ hot water for making tea, the user can open the tankless pipeline machine 2 for use. When the user needs to take domestic water for washing tableware or washing vegetables and fruits or washing clothes, the user can open the faucet 4 for use.

[0031] Please continue to refer to Figure 1 However, the independent pressure reducing valve and flow divider are respectively installed in the water purification system, which occupies more space and causes pipeline layout to be messy, increasing installation difficulty. Moreover, when a fault occurs, the pressure reducing valve and the flow divider need to be detected and repaired separately, and replacement of the pressure reducing valve and / or the flow divider in the limited space will greatly increase the complexity of operation and maintenance cost. Therefore, in view of the existing problems, the water purification system can further comprise a flow divider 1, wherein the faucet 4, the tankless pipeline machine 2, the water purifier 3 and the tap water supply pipeline are all in communication with the flow divider 1, so that the water supply pipeline can introduce tap water to the flow divider 1 and adjust and maintain the excessively high and unstable water pressure of the tap water in the water supply pipeline within a preset pressure value range, finally generating stabilized water and delivering it to the water purifier 3. The water purifier 3 will generate pure water after deep filtration and purification treatment of the stabilized water, and the purified pure water from the water purifier 3 can flow into the flow divider 1, and then be introduced to the tankless pipeline machine 2 and the faucet 4 through the flow divider 1. The pure water flowing to the faucet 4 will be used as domestic water, and the pure water flowing to the tankless pipeline machine 2 will be used as direct drinking water.

[0032] The tankless pipeline machine 2 will be described in detail below.

[0033] Please refer to Figures 2-4, the water tankless pipeline machine 2 based on the embodiment of the present application, since it is designed without water tank, on the one hand, it does not occupy too much space, to realize the miniaturization of the water tankless pipeline machine 2, on the other hand, since the water tankless pipeline machine 2 does not need to store water, thus there is no need to maintain the water temperature of the water tank, reducing the energy consumption, at the same time, avoiding the problem that bacteria are easy to breed in the traditional water tank pipeline machine, thereby improving the water quality of the water tankless pipeline machine 2. Wherein, the water tankless pipeline machine 2 can include a shell 21 and a waterway system 22.

[0034] Specifically, the shell 21 is usually made of high-quality plastic materials such as high-density polyethylene, which has the characteristics of high strength, wear resistance, acid and alkali corrosion resistance, waterproof, shockproof and other characteristics, and can maintain stable performance in various harsh environments, so as to ensure the normal work of the water tankless pipeline machine 2. The shell 21 has a water inlet 211 and a water outlet 212, wherein the water inlet 211 is in communication with the pure water outlet 32 in the water purifier 3, so that the purified pure water in the water purifier 3 flows from the pure water outlet 32 to the water inlet 211 and then flows into the waterway system 22, and then flows out from the water outlet 212 for user use.

[0035] Please refer to Figure 2 and Figure 4 , the waterway system 22 is arranged in the shell 21, so that the shell 21 plays a role in protecting the parts in the waterway system 22. The waterway system 22 can include a first water inlet electromagnetic valve 2211 and a flow control pump 2213 arranged in sequence along the flow direction of the water flow, wherein the first water inlet electromagnetic valve 2211 is in communication with the water inlet 211, and the flow control pump 2213 is in communication with the water outlet 212. It can be understood that the first water inlet electromagnetic valve 2211 is used to control the entry of the purified water of the water dispenser, and the first water inlet electromagnetic valve 2211 is closed or opened by the attraction and release of the electromagnet; the flow control pump 2213 is used to ensure the stable flow of the water flow in the waterway system 22 and is responsible for providing the power of the water flow, and adjusts the size of the water flow according to the actual demand; that is, when the water tankless pipeline machine 2 is working normally, the first water inlet electromagnetic valve 2211 is opened, and the flow control pump 2213 starts to work, the purified water in the water purifier 3 can flow from the water inlet 211, pass through the first water inlet electromagnetic valve 2211 and the flow control pump 2213, and then flow out from the water outlet 212 for user use, wherein the flow control pump 2213 can adjust the size of the water flow according to the user's demand, to avoid too much water flow from the water tankless pipeline machine 2; when the water tankless pipeline machine 2 stops working, the first water inlet electromagnetic valve 2211 is closed, and the flow control pump 2213 stops working, to avoid the water flow continuing to flow out from the water outlet 212, thereby reducing the waste of water.

[0036] Please continue to refer to Figure 2 and Figure 4In some embodiments, the tankless pipeline machine 2 further comprises a quick heating device 25, which is arranged between the water outlet nozzle 212 and the flow control pump 2213 to heat the water flow passing through the quick heating device 25. It can be understood that the quick heating device 25 is generally used to quickly heat the water flow by using an electric heating element; that is, when the user needs hot water, the quick heating device 25 works, at this time, the water flow is quickly heated to a set stable temperature after flowing through the electric heating element in the quick heating device 25, so as to realize the hot water outlet of the tankless pipeline machine. In addition, the embodiment of the present application uses the quick heating device 25 to heat the water flow, which can improve the energy efficiency of the tankless pipeline machine 2; that is, the quick heating device 25 uses the quick heating technology, when the user needs hot water, the tankless pipeline machine 2 can discharge hot water at a set temperature according to the user's demand, so that on the one hand, the heat loss can be reduced, and on the other hand, the user does not need to wait for the heating time of the hot water, thereby saving the user's water receiving time.

[0037] Furthermore, the type of the quick heating device 25 is not specifically limited in the embodiment of the present application. Exemplarily, the quick heating device 25 can be one of a quartz tube heating type, a thick film heating type and an electromagnetic heating type. Among them, the quartz tube heating type uses a quartz tube as a heating body, an electric heating wire is wound on the outer wall of the quartz tube, and the water flow in the quartz tube is heated by electric current, and this heating method has the advantages of fast heating speed, high temperature resistance and corrosion resistance. The thick film heating type uses thick film heating technology to directly print an electric heating element on the heating body to form a uniform heating film, and this heating method has the characteristics of high heating efficiency, fast thermal response speed and long service life. The electromagnetic heating type uses the principle of electromagnetic induction to generate eddy current in the heating body by electromagnetic field, thereby heating the water flow, and this heating method has the advantages of uniform heating, no open flame, safety and reliability.

[0038] It should be noted that when the user needs to receive normal temperature water, the quick heating device 25 is in an inactive state, so that even if the water flow passes through the quick heating device 25, the electric heating element in the quick heating device 25 will not heat the water flow, so that the water outlet nozzle 212 of the tankless pipeline machine 2 flows out normal temperature water. Of course, in other embodiments, a normal temperature water path can be additionally arranged in the water path system 22, which is not specifically limited in the present application.

[0039] Please refer to Figures 4-5In some embodiments, the tankless pipeline machine 2 further comprises an electric control device 24, which is arranged in the shell 21 and electrically connected with the first water inlet electromagnetic valve 2211, the flow control pump 2213 and the instant heating device 25 to control the opening and closing of the first water inlet electromagnetic valve 2211, the flow control pump 2213 and the instant heating device 25. It can be understood that when the user uses the tankless pipeline machine 2 and needs to take hot water, the electric control device 24 can control the first water inlet electromagnetic valve 2211 to open, and the flow control pump 2213 and the instant heating device 25 to work, so that the water outlet nozzle 212 of the tankless pipeline machine discharges the water temperature and water volume required by the user.

[0040] Please continue to refer to Figures 4-5 Further, in order to optimize the heat management of the tankless pipeline machine 2 and avoid unnecessary heat transfer superposition between the electric control device 24 and the instant heating device 25, in some embodiments, a strong electric installation area 214 and a weak electric installation area 213 are arranged in the shell 21, and the strong electric installation area 214 and the weak electric installation area 213 are arranged in the length direction of the tankless pipeline machine 2, wherein the electric control device 24 is installed in the weak electric installation area 213, and the instant heating device 25 is installed in the strong electric installation area 214. It can be understood that the instant heating device 25 needs strong electric power supply, and the strong electric power has the characteristics of high voltage and large current; the electric control device 24 needs weak electric power supply, and the weak electric power has the characteristics of low voltage and small current, therefore, in the length direction of the tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are arranged in a spaced manner, so that the electromagnetic interference can be reduced to ensure the stability and reliability of the electric signal of the electric control device 24.

[0041] It should be noted that the above-mentioned strong electric installation area 214 can be understood as an electric control installation area.

[0042] Further, the strong electric installation area 214 can be divided into an instant heating installation area 2142 and a waterway installation area 2141, wherein the first water inlet electromagnetic valve 2211, the flow control pump 2213 and the water volume sensor 2215 are installed in the waterway installation area 2141, and the instant heating device 25 is installed in the instant heating installation area 2142, and in the length direction of the tankless pipeline machine 2, the waterway installation area 2141 is located between the weak electric installation area 213 and the instant heating installation area 2142; that is, in the length direction of the tankless pipeline machine 2, the electric control device 24, the waterway system 22 and the instant heating device 25 are arranged side by side, and a thermal isolation barrier is formed by the waterway system 22 to separate the electric control device 24 and the instant heating device 25, so that the thermal energy interaction interference is reduced.

[0043] Please continue to refer to Figures 4-5In some embodiments, the tankless pipeline machine 2 further comprises a power line 26, the power line 26 can supply power to the devices of the water system 22 and the electric control device 24, and part of the power line 26 is arranged in the water installation area 2141 to separate the power line 26 from the instant heating device 25; that is, in the length direction of the tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are arranged separately, and at the same time, since the instant heating device 25 and the electric control device 24 will generate heat during operation, the power line 26 close to the instant heating device 25 or the electric control device 24 will affect the power line 26, therefore, the embodiment of the application arranges the power line 26 in the water installation area 2141, and the water installation area 2141 is located between the instant heating installation area 2142 and the weak current installation area 213, in this way, the heat energy interaction interference is reduced.

[0044] Please refer to Figure 4 Further, the shell 21 further has a groove 216, the power line 26 and the water inlet 211 connected with the first water inlet electromagnetic valve 2211 are located in the same groove 216; that is, the power line 26 and the first water inlet electromagnetic valve 2211 are located in the same groove 216, in this way, when producing the shell 21 of the tankless pipeline machine 2, it is not necessary to open another groove 216 on other places of the shell 21, in this way, the production efficiency of the tankless pipeline machine 2 can be improved.

[0045] Please refer to Figure 2 and Figure 5In some embodiments, the waterway system 22 further comprises a water quantity sensor 2215, which can be arranged between the water inlet 211 and the first water inlet electromagnetic valve 2211, or arranged between the first water inlet electromagnetic valve 2211 and the flow control pump 2213, or arranged between the flow control pump 2213 and the water outlet nozzle 212, and the present application does not make specific limitation on this. The water quantity sensor 2215 comprises two polar plates, when there is sufficient water quantity in the waterway system 22 flowing through the water quantity sensor 2215, at this time the water flow will flow through the two polar plates, so that the water quantity sensor 2215 generates an electrical signal and sends a changed signal to the electronic control device 24. Since the electrical signal generated by the water flow flowing through the two polar plates is inconsistent with the electrical signal generated by the air or less water flow flowing through the two polar plates, the electronic control device 24 can determine the water quantity in the waterway system 22 according to the electrical signal received. It can be understood that when the instant heating device 25 is arranged in the tankless pipeline machine 2, the instant heating device 25 is electrically connected with the electronic control device 24, and the water quantity sensor 2215 can play a role in protecting the instant heating device 25; that is, when the user needs to use hot water, the instant heating device 25 works, but due to insufficient water quantity in the waterway system 22, the electric heating element in the instant heating device 25 is exposed to the air and continues to heat, so that the instant heating device 25 is in dry burning, which leads to overheating of the instant heating device 25, so that the instant heating device 25 is easily burned out, and the instant heating device 25 is easy to produce high-temperature steam in the heating process, if the tankless pipeline machine 2 is used in the case of insufficient water quantity in the waterway system 22, high-temperature steam is easy to be sprayed at the water outlet nozzle 212, which can cause harm to the user; therefore, the water quantity sensor 2215 arranged in the present application can monitor the water quantity information in the waterway system 22 in real time, and feed back the monitored water quantity information in the waterway system 22 to the control device of the tankless pipeline machine 2, and the control device determines the water quantity in the waterway system 22 according to the set water shortage logic, when the water quantity in the water quantity system is lower than the preset threshold value, it indicates that the water quantity in the waterway system 22 is insufficient, the control device controls the instant heating device 25 to stop working or reduces the power of the instant heating device 25, so as to prevent the occurrence of dry burning phenomenon, so as to protect the instant heating device 25 and ensure the safety of the tankless pipeline machine 2. In addition, the water quantity sensor 2215 can realize the effect of energy saving and power saving by intelligently controlling the power of the instant heating device 25, and reduce the electricity cost of the user.

[0046] Please continue to refer to Figure 2 and Figure 5In some embodiments, the waterway system 22 further comprises a flow meter 2216, which can be arranged between the water inlet 211 and the first water inlet electromagnetic valve 2211, or arranged between the first water inlet electromagnetic valve 2211 and the flow control pump 2213, or arranged between the flow control pump 2213 and the water outlet nozzle 212, which is not limited in the embodiments of the present application. The flow meter 2216 is used to detect the flow of water flowing through the waterway system 22, that is, when the user inputs a quantitative water taking value to the water tankless pipeline machine 2, the first water inlet electromagnetic valve 2211 is opened, the flow control pump 2213 is working, and the flow meter 2216 starts to detect the flow of water flowing through the waterway system 22 and sends it to the control device of the water tankless pipeline machine 2. When the flow meter 2216 detects that the flow of water flowing through the waterway system 22 reaches the water taking value required by the user, the control device controls the first water inlet electromagnetic valve 2211 to be closed, and the flow control pump 2213 and the flow meter 2216 stop working. Thus, the embodiments of the present application can improve the detection of the flow of water flowing through the waterway system 22 and the accuracy of controlling the amount of water discharged by the water tankless pipeline machine 2 by arranging the flow meter 2216.

[0047] Please refer to Figures 4-5 In another embodiment, the waterway system 22 can simultaneously comprise a water amount sensor 2215 and a flow meter 2216, wherein the water amount sensor 2215 and the flow meter 2216 are arranged between the water inlet 211 and the water outlet nozzle 212, and the water amount sensor 2215 and the flow meter 2216 have the above-mentioned functions, which will not be described herein again. It should be noted that Figure 4 is an arrangement of the water amount sensor 2215, the flow meter 2216, the first water inlet electromagnetic valve 2211 and the flow control pump 2213 in the waterway system 22; Figure 5 is another arrangement of the water amount sensor 2215, the flow meter 2216, the first water inlet electromagnetic valve 2211 and the flow control pump 2213 in the waterway system 22.

[0048] Please refer to Figures 6-7 In some embodiments, the water tankless pipeline machine 2 further comprises a sterilization device 23, which is arranged between the instant heating device 25 and the water outlet nozzle 212, or arranged upstream of the instant heating device 25, which is not limited in the embodiments of the present application. It can be understood that the sterilization device 23 can effectively kill bacteria, viruses and other microorganisms in the water flow to ensure the safety and hygiene of the water quality, thereby improving the water quality of the water tankless pipeline machine 2. The sterilization device 23 can be in the form of an ultraviolet sterilizer or an ozone sterilizer, and such sterilization device 23 can effectively sterilize without producing chemical residues, thereby reducing pollution to the environment; in addition, these devices are usually designed to be compact, easy to install and maintain.

[0049] Please continue to see Figures 6-7 In some embodiments, the waterway system 22 further comprises a check valve 2218 arranged at the water outlet nozzle 212 to prevent water dripping from the water outlet nozzle 212. It can be understood that the waterway system 22 further comprises a water outlet pipeline 29 for connecting the instant heating device 25 and the water outlet nozzle 212. When the instant heating device 25 is used to heat the water in the waterway system 22, the water in the waterway system 22 is difficult to be heated to 100 degrees Celsius due to the rapid heating of the instant heating device 25. Therefore, the check valve 2218 arranged at the water outlet nozzle 212 in the embodiments of the present application can play a pressure bearing role to increase the boiling point of the water in the water outlet pipeline 29, so that the water boils, and water vapor can be arranged in the water outlet pipeline 29. Since the water outlet pipeline 29 is connected to the water outlet nozzle 212, the water outlet nozzle 212 can discharge water vapor, so that the water outlet nozzle 212 can flow out a stable water column.

[0050] Furthermore, the check valve 2218 can correspond to a one-way valve to prevent water flow from flowing backward in the water outlet pipeline 29, and to protect other components in the waterway system 22, such as the flow control pump 2213 and the instant heating device 25, from being impacted and damaged by reverse water flow.

[0051] It should be noted that the electric control device 24 is also electrically connected to the water quantity sensor 2215, the flow meter 2216, the check valve 2218, and the sterilization device 23. In this way, the electric control device 24 can accurately adjust the water flow speed, water temperature and other parameters through preset programs and algorithms, thereby meeting different needs of users.

[0052] Please see Figure 3 In some embodiments, the tankless pipeline machine 2 further comprises an irradiation lamp 28 arranged on the shell 21 and facing a water containing area of the tankless pipeline machine 2, so that light emitted by the irradiation lamp 28 irradiates the water containing area below the water outlet nozzle 212. It can be understood that the irradiation lamp 28 can provide auxiliary lighting for the water outlet nozzle 212, that is, provide lighting for the water containing area below the water outlet nozzle 212, so as to facilitate users to observe the water containing area in a dimly lit environment, so that users can accurately operate the tankless pipeline machine 2 based on the water outlet condition, without the need for additional lighting devices, reducing the risk of misoperation and safety hazards caused by blurred vision, improving the convenience of using the tankless pipeline machine 2, and providing additional protection for the safety of users taking water.

[0053] Furthermore, in order to ensure that the irradiation lamp 28 can effectively irradiate the water containing area below the water outlet nozzle 212, the irradiation lamp 28 is mounted on the shell 21 and at least partially protrudes from the shell 21, so as to ensure that the irradiation side of the irradiation lamp 28 and the water outlet side of the water outlet nozzle 212 are consistent, so that the irradiation lamp 28 provides sufficient irradiation range.

[0054] Please continue to see Figure 3 In some embodiments, the tankless pipeline machine 2 further comprises a display device 27 arranged on the housing 21 to display the working information of the tankless pipeline machine 2.
