DETAILED DESCRIPTION

[0026] In order to make the objectives, technical solutions and advantages of the present application more clear, 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 can include a heater, which can heat the water in the pipeline machine to facilitate the user to obtain hot water. However, since there is no feedback on the amount of water in the flow path of the pipeline machine, the heater continues to heat even in the case of water shortage in the flow path, which can cause the heater to burn out and thus damage 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 is used to perform deep filtration and purification treatment on the tap water to make the water quality of the water source meet the standard of safe drinking or meet 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 purified pure water in 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 to heat or cool the purified pure water in real time to facilitate the user to accurately obtain drinking water and meet the different drinking water temperature requirements of the user.

[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 the utilization efficiency of water, 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 the pipeline layout to be messy, increasing the installation difficulty. Moreover, when a fault occurs, the pressure reducing valve and the flow divider need to be detected and repaired separately, and replacing the pressure reducing valve and / or the flow divider in the limited space will greatly increase the operation complexity 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 the excessive and unstable water pressure of the tap water in the water supply pipeline and keep it 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 will 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 no need to maintain the water temperature of the water tank, reduce the energy consumption, at the same time, avoid the problem that the bacteria is easy to breed in the traditional water tank pipeline machine, and then improve the water quality of the water tankless pipeline machine 2. Wherein, the water tankless pipeline machine 2 can include a shell 21 and a water 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 it can 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 water in the water purifier 3 flows from the pure water outlet 32 to the water inlet 211 and then flows into the water system 22, and then flows out from the water outlet 212 for use by the user.

[0035] Please refer to Figure 2 and Figure 4The waterway system 22 is arranged in the shell 21 to protect the components in the waterway system 22. The waterway system 22 can include a first water inlet electromagnetic valve 2211, a negative pressure valve 2217 and a water pump 2214 arranged in sequence along the flow direction of the water flow. It can be understood that the first water inlet electromagnetic valve 2211 is used to control the entry of 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 water pump 2214 is responsible for providing the power of the water flow, and the water pump 2214 drives the impeller to rotate by the motor to generate centrifugal force of the liquid, thereby achieving the transportation of the water flow. In this process, the voltage is the driving source of the motor; that is, when the voltage is large, the speed of the motor driving the impeller to rotate is fast, so that the speed of the water flow flowing through the water pump 2214 is accelerated, so that the flow of the water flow flowing through the water pump 2214 is more, thereby achieving the adjustment of the flow of the water flow. The negative pressure valve 2217 is connected between the first water inlet electromagnetic valve 2211 and the water pump 2214. That is, when the water flow in the waterway system 22 is cut off or the water pump 2214 stops working, the negative pressure valve 2217 can prevent negative pressure (i.e. pressure lower than atmospheric pressure) in the pipeline. Negative pressure can cause pipe rupture, water hammer phenomenon (pressure impact due to sudden stop or change of direction of water flow) or other damage. The negative pressure valve 2217 can maintain positive pressure in the pipeline or at least prevent the generation of negative pressure, thereby protecting the water pump 2214, valves, pipelines and other components in the system from damage. The negative pressure valve 2217 has various ways to prevent the generation of negative pressure, such as air supplement method, pre-pressurization method, etc. Furthermore, the negative pressure valve 2217 in the embodiment of the application is a mechanical negative pressure valve 2217, that is, when the tankless line machine 2 is working normally, the first water inlet electromagnetic valve 2211 is opened, and the purified water filtered by the purified water machine 3 flows from the purified water outlet 32 to the water inlet 211 and then flows into the first water inlet electromagnetic valve 2211. At this time, the water pump 2214 works, and negative pressure is generated at both ends of the negative pressure valve 2217, so that the negative pressure valve 2217 is opened to control the water flow from the negative pressure valve 2217. The specific structure and principle of the negative pressure valve 2217 have been disclosed in the related art, and will not be repeated here.

[0036] Please refer to Figure 4 The tankless line machine 2 further includes an electric control device 24 arranged in the shell 21, and the electric control device 24 is electrically connected with the first water inlet electromagnetic valve 2211 and the water pump 2214.

[0037] Please refer to Figure 2 and Figure 4The waterway system 22 further comprises a water quantity sensor 2215 electrically connected with the electric control device 24. The water quantity sensor 2215 can be arranged between the water inlet 211 and the first water inlet electromagnetic valve 2211, so that the water quantity sensor 2215 is in communication with the water inlet 211; or the water quantity sensor 2215 is arranged between the first water inlet electromagnetic valve 2211 and the water pump 2214, or the water quantity sensor 2215 is arranged between the water pump 2214 and the water outlet nozzle 212, so that the water quantity sensor 2215 is in communication with the water outlet nozzle 212. The present application does not make specific limitations on this. The water quantity sensor 2215 comprises two polar plates. When there is sufficient water in the waterway system 22 flowing through the water quantity sensor 2215, the water flow will flow through the two polar plates at this time, so that the water quantity sensor 2215 generates an electric signal and sends a changed signal to the electric control device 24. Since the electric signal generated by the water flow flowing through the two polar plates is inconsistent with the electric signal generated by the water flow flowing through the two polar plates when there is less air or water, the electric control device 24 can determine the water quantity in the waterway system 22 according to the received electric signal. It can be understood that when the instant heating device 25 is arranged in the water tankless pipeline machine 2, the instant heating device 25 is electrically connected with the electric control device 24, and the water quantity sensor 2215 can protect 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 in the waterway system 22, the electric heating element in the instant heating device 25 is exposed to the air and continuously heated, so that the instant heating device 25 is in dry burning, which leads to overheating of the instant heating device 25. Thus, the instant heating device 25 is easily burned out, and high-temperature steam is easily generated in the heating process of the instant heating device 25. If the water tankless pipeline machine 2 is used when the water quantity in the waterway system 22 is insufficient, high-temperature steam is easily 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 water tankless pipeline machine 2. 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 to prevent dry burning and protect the instant heating device 25, thereby ensuring the safety of the water tankless pipeline machine 2 and protecting the water tankless pipeline machine 2. Furthermore, 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, thereby reducing the electricity cost of the user.

[0038] The water amount sensor 2215 is arranged in the waterway system 22 to feed back the water amount information of the waterway system 22. That is, when the tankless pipeline machine 2 is working, the water amount sensor 2215 works in real time to detect the water amount information of the waterway system 22 and feed back the detected water amount information to the tankless pipeline machine 2. The tankless pipeline machine 2 can determine whether the waterway system 22 is short of water according to the received water amount information and the set water shortage determination logic. When the waterway system 22 is short of water, the tankless pipeline machine 2 is controlled to stop working, so as to protect the tankless pipeline machine 2.

[0039] Please refer to Figures 4-5 In some embodiments, the tankless pipeline machine 2 further comprises a heating device 25 arranged between the water outlet nozzle 212 and the water pump 2214 or arranged between the water outlet nozzle 212 and the water amount sensor 2215, and the heating device 25 heats the water flow passing through the heating device 25. It can be understood that the heating device 25 usually uses an electric heating element to quickly heat the water flow. That is, when the user needs hot water, the heating device 25 works, and at this time, the water flow passing through the electric heating element in the heating device 25 is quickly heated to a set stable temperature, so as to realize the tankless pipeline machine to discharge hot water. In addition, the heating device 25 is used to heat the water flow in the embodiments of the present application, which can improve the energy efficiency of the tankless pipeline machine 2. That is, 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 by using the heating technology of the heating device 25. In this way, on the one hand, the heat loss can be reduced, and on the other hand, the user does not need to wait for a long time for the hot water to be heated, so as to save the user's water receiving time.

[0040] Furthermore, the type of the heating device 25 is not limited in the embodiments of the present application. For example, the heating device 25 can be one of a quartz tube heating type, a thick film heating type and an electromagnetic heating type. 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. 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 a heating body to form a uniform heating film. This heating method has the characteristics of high heating efficiency, fast thermal response speed and long service life. The electromagnetic heating type uses electromagnetic induction principle to generate eddy current in the heating body by electromagnetic field, so as to heat the water flow. This heating method has the advantages of uniform heating, no open flame and safety and reliability.

[0041] It should be noted that when the user needs to get normal temperature water, the instant heating device 25 is in a non-working state, so even if the water flow flows through the instant heating device 25, the electric heating element in the instant heating device 25 will not heat the water flow, so that the water outlet nozzle 212 of the water tankless pipeline machine 2 flows out normal temperature water. Of course, in other embodiments, a normal temperature water path can be additionally provided in the water path system 22, which is not limited in the application.

[0042] Please continue to refer to Figures 4-5 In some embodiments, the water path 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, so that the flow meter 2216 is in communication with the water inlet 211; or the flow meter 2216 is arranged between the first water inlet electromagnetic valve 2211 and the water pump 2214, or the flow meter 2216 is arranged between the water pump 2214 and the water outlet nozzle 212, so that the flow meter 2216 is in communication with the water outlet nozzle 212, which is not limited in the embodiments of the application. Among them, the flow meter 2216 is used to detect the flow of the water flow flowing through the water path 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 water pump 2214 is working, and the flow meter 2216 starts to detect the flow of the water flow flowing through the water path 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 the water flow flowing through the water path 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 water pump 2214 and the flow meter 2216 stop working. In this way, the embodiments of the application can improve the detection of the flow of the water flow flowing through the water path 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.

[0043] It should be noted that, Figure 4 is one arrangement of the water amount sensor 2215, the flow meter 2216, the first water inlet electromagnetic valve 2211, the negative pressure valve 2217 and the water pump 2214 in the water path system 22; Figure 5 is another arrangement of the water amount sensor 2215, the flow meter 2216, the first water inlet electromagnetic valve 2211, the negative pressure valve 2217 and the water pump 2214 in the water path system 22.

[0044] Please refer to Figures 6-7In some embodiments, the 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. It can be understood that the sterilization device 23 can effectively kill bacteria, viruses and other microorganisms in the water flow, so as to ensure the safety and hygiene of the water quality, thereby improving the water quality of the 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 chemical residues, thereby reducing pollution to the environment. In addition, these devices are usually designed compactly, easy to install and maintain.

[0045] Please refer to Figure 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 tankless pipeline machine 2 uses the instant heating device 25 to heat the water in the waterway system 22, it is difficult for the instant heating device 25 to heat the water in the waterway system 22 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 improve the boiling point of the water in the water outlet pipeline 29, so that the water boils. In the process of boiling, water vapor can be arranged in the water outlet pipeline 29, and since the water outlet pipeline 29 is connected to the water outlet nozzle 212, the water outlet nozzle 212 can discharge the water vapor, so that the water outlet nozzle 212 can flow out a stable water column.

[0046] Furthermore, the check valve 2218 can be equivalent 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 water pump 2214, the instant heating device 25, etc., from being impacted and damaged by the reverse water flow.

[0047] Please refer to Figures 4-5 In some embodiments, when a 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 water pump 2214 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. Of course, the electric control device 24 is also electrically connected with the flow meter 2216, the instant heating device 25 and the sterilization device 23, so that 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.

[0048] 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 are arranged in the shell 21, and the strong electric installation area 214 is arranged separately from the weak electric installation area in the length direction of the tankless pipeline machine 2, wherein the electric control device 24 is installed in the weak electric installation area, 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 to be powered by strong electricity, and the strong electricity has the characteristics of high voltage and large current; the electric control device 24 needs to be powered by weak electricity, and the weak electricity has the characteristics of low voltage and small current, therefore, the electric control device 24 and the instant heating device 25 are arranged separately in the length direction of the tankless pipeline machine 2, so that the electromagnetic interference can be reduced to ensure the stability and reliability of the electric signal of the electric control device 24.

[0049] It should be noted that the above-mentioned weak electric installation area can be understood as the electric control installation area 213; that is, the electric control device 24 is installed in the electric control installation area 213.

[0050] 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 water pump 2214, the water quantity sensor 2215, and the flow meter 2216 are all installed in the waterway installation area 2141, 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 electric control 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.

[0051] Please refer to Figure 4 In some embodiments, the tankless pipeline machine 2 further comprises a power line 26, which can power the devices of the waterway system 22 and the electric control device 24, and part of the power line 26 is arranged in the waterway 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 since the instant heating device 25 and the electric control device 24 will both 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, in the embodiments of the present application, the power line 26 is arranged in the waterway installation area 2141, and the waterway installation area 2141 is located between the instant heating installation area 2142 and the electric control installation area 213, so that the thermal energy interaction interference is reduced.
