DETAILED DESCRIPTION

[0028] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0029] In the related art, the pipeline machine can include a control module and an electric wire, and the control module is usually weak current and the electric wire is usually strong current. In actual application, the installation of the electric wire is dependent on the wiring between the control module, which easily causes the electric wire and the control module to be close to each other, thereby causing heat coupling between the electric wire and the control module, resulting in damage to the internal parts of the control module.

[0030] In order to solve the above problems, the present application provides a pure drinking system, which is a comprehensive system integrating water purification treatment and convenient drinking water functions. The pure drinking system can be applied to places such as homes, offices, schools, hospitals, etc., which are not specifically limited by the present application.

[0031] Please refer to Figure 1, the net drinking system comprises a water purifier 3 and a water tankless 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 filter screen to filter out large particles in tap water. The precision filtering uses more advanced filtering technology to remove small molecules, harmful substances and other substances in tap water. The post-treatment may include activated carbon adsorption to improve the taste of water. The water purifier 3 also has a pure water outlet 32, and the water tankless 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 tankless pipeline machine 2, and the water tankless pipeline machine 2 is used for instant heating or cooling of the purified pure water, so that the user can accurately obtain drinking water and meet the user's different drinking water temperature requirements.

[0032] Please continue to read Figure 1 In some embodiments, the net drinking system can also include a faucet 4, which can be directly connected to 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 providing tap water to the water purifier 3 may change due to various factors (such as water supply peak period, 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, to avoid physical damage to the water purifier 3 due to high water pressure. In order to distribute the purified pure water to the water tankless pipeline machine 2 and the faucet 4 at the same time, improve the utilization efficiency of water, the pure water outlet 32 of the water purifier 3 is usually configured with a flow valve, and the water inlet end of the water tankless pipeline machine 2 and the water inlet of the faucet 4 are in communication with the flow valve. When the user needs to take temperature-adjusted drinking water, such as drinking 5℃-15℃ ice water in hot summer, or taking 40℃-50℃ warm water to wash milk powder, or taking 90℃-99℃ hot water to make tea, etc., the user can open the water tankless pipeline machine 2 to take. When the user needs to take domestic water to wash tableware or wash vegetables and fruits or wash clothes, the user can open the faucet 4 to take.

[0033] Please continue to read Figure 1However, the independent pressure reducing valve and the independent 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 the replacement of 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 include the flow divider 1, wherein the faucet 4, the tankless pipeline machine 2, the water purifier 3 and the tap water supply pipeline are all connected to the flow divider 1, so that the tap water supply pipeline can introduce tap water to the flow divider 1, and the excessively high and unstable water pressure of the tap water in the tap water supply pipeline is adjusted and kept within a preset pressure value range, and finally generates stabilized water and is transported to the water purifier 3, which generates pure water after deep filtration and purification treatment of the stabilized water, and the pure water purified by 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 drunk as direct drinking water.

[0034] The tankless pipeline machine 2 will be described in detail below.

[0035] Based on the tankless pipeline machine 2 of the embodiment of the present application, since it is designed without a water tank, on the one hand, it does not occupy too much space to realize the miniaturization of the tankless pipeline machine 2, and on the other hand, since the tankless pipeline machine 2 does not need to store water, it is not necessary to maintain the water temperature of the water tank, thereby reducing the energy consumption and avoiding the problem that bacteria are easily bred in the traditional pipeline machine with a water tank, and thus improving the water quality of the tankless pipeline machine 2.

[0036] Please refer to Figures 2-4 The tankless pipeline machine 2 can include a shell 21, which 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, waterproofness, shock resistance and the like, and can maintain stable performance in various harsh environments, so as to ensure the normal work of the tankless pipeline machine 2.

[0037] Please refer to Figures 3-4The water tank-free pipeline machine 2 comprises an electric control device 24, an instant heating device 25, and a power line 26, wherein the power line 26 is electrically connected with the electric control device 24 and the instant heating device 25 to supply power to the electric control device 24 and the instant heating device 25; the electric control device 24 is electrically connected with the instant heating device 25 to control the working of the instant heating device 25; the instant heating device 25 is usually used to rapidly heat the water flow by using an electric heating element; that is, when the user needs hot water, the instant heating device 25 works, at this time, the water flow is rapidly heated to a set stable temperature after flowing through the electric heating element in the instant heating device 25, so as to realize the hot water output of the water tank-free pipeline machine. In addition, the water flow is heated by the instant heating device 25 in the embodiment, which can improve the energy efficiency of the water tank-free pipeline machine 2; that is, when the user needs hot water, the water tank-free 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.

[0038] Furthermore, the type of the instant heating device 25 is not limited in the embodiment. For example, the instant 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, 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 a 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 the electromagnetic field to heat the water flow, and this heating method has the advantages of uniform heating, no open flame, and safety and reliability.

[0039] It should be noted that when the user needs to receive normal temperature water, the instant heating device 25 is in a non-working state, so that 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 tank-free pipeline machine 2 flows out normal temperature water.

[0040] Please continue to refer to Figures 3-4Further, in order to optimize the heat management of the water tankless pipeline machine 2, avoid unnecessary heat transfer superposition between the electric control device 24 and the instant heating device 25, a strong electricity installation area 214 and a weak electricity installation area 213 are arranged in the shell 21, the electric control device 24 is arranged in the weak electricity installation area 213, the instant heating device 25 is arranged in the strong electricity installation area 214, and part of the power line 26 is arranged in the strong electricity installation area 214. It can be understood that 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; 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 power line 26 needs to be electrically connected with an external power supply to supply power to the devices in the water tankless pipeline machine 2, therefore, by arranging the power line 26 in the strong electricity installation area 214 and the electric control device 24 in the weak electricity installation area 213, heat coupling between the power line 26 and the electric control device 24 can be avoided, thereby avoiding damage to the internal devices of the electric control device 24, so that the electric control device 24 and the power line 26 are protected.

[0041] It should be noted that the weak electricity installation area 213 described above can be understood as an electric control installation area.

[0042] Please continue to refer to Figures 3-4 In some embodiments, the strong electricity installation area 214 includes an instant heating installation area 2142 and a water channel installation area 2141, and the water channel installation area 2141 is located between the instant heating installation area 2142 and the weak electricity installation area 213; that is, in the length direction of the water tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are arranged side by side, and the water channel installation area 2141 forms a thermal isolation barrier to separate the electric control device 24 and the instant heating device 25, so as to reduce thermal energy interaction interference.

[0043] Please continue to refer to Figures 3-4 In some embodiments, part of the power line 26 is arranged in the water channel installation area 2141 to separate the power line 26 from the instant heating device 25; that is, in the length direction of the water tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are arranged side by side, and 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 power line 26 is arranged in the water channel installation area 2141, and the water channel installation area 2141 is located between the instant heating installation area 2142 and the weak electricity installation area 213, so as to reduce thermal energy interaction interference.

[0044] Please refer to Figure 5 and Figure 6In some embodiments, the water tankless pipeline machine 2 further comprises a water circuit system 22, which is arranged in the water circuit installation area 2141 and is electrically connected with the power line 26 and the electric control device 24, so that the power line 26 supplies power to the water circuit system 22, and the electric control device 24 is used to control the operation of some devices in the water circuit system 22; the water circuit system 22 is also in communication with the instant heating device 25, so that the instant heating device 25 can heat the water in the water circuit system 22 to achieve the discharge of hot water by the water tankless pipeline machine 2.

[0045] Please continue to refer to Figure 5 and Figure 6 In some embodiments, 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 of the water purifier 3, so that the purified pure water from the pure water outlet 32 of the water purifier 3 flows into the water circuit system 22 after flowing into the water inlet 211, and then flows out from the water outlet 212 for use by the user.

[0046] Please refer to Figure 3 and Figure 5 The water circuit system 22 is arranged in the shell 21 to protect the parts in the water circuit system 22. The water circuit system 22 can include a first water inlet electromagnetic valve 2211 and a pump assembly 2212 arranged in sequence along the flow direction of the water flow, and the first water inlet electromagnetic valve 2211 is in communication with the water inlet 211. It can be understood that the first water inlet electromagnetic valve 2211 is used to control the entry of pure 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 pump assembly 2212 is responsible for providing power to the water flow, and the water pump 2214 drives the impeller to rotate by the motor to generate centrifugal force on the liquid, thereby achieving the transportation of the water flow, and in this process, the voltage is used as the motor driving source; that is, when the voltage is large, the motor drives the impeller to rotate at a faster speed, 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 larger, thereby achieving the adjustment of the flow of the water flow.

[0047] Further, the pump assembly 2212 is in communication with the instant heating device 25, the instant heating device 25 is in communication with the water outlet 212, and the electric control device 24 is electrically connected with the first water inlet electromagnetic valve 2211, the pump assembly 2212 and the instant heating device 25. When the user uses the water 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 212 of the water tankless pipeline machine 2 discharges the water temperature and water volume required by the user, thereby achieving the discharge of hot water by the water tankless pipeline machine 2.

[0048] Please refer to Figure 3In some embodiments, the shell 21 further has a recess 216, and the power cord 26 and the water inlet 211 connected to the first water inlet electromagnetic valve 2211 are located in the same recess 216; that is, the power cord 26 and the first water inlet electromagnetic valve 2211 are located in the same recess 216, so that when the shell 21 of the water tankless pipeline machine 2 is produced, another recess 216 does not need to be opened on other places of the shell 21, so that the production efficiency of the water tankless pipeline machine can be improved.

[0049] Please refer to Figures 7-8 In some embodiments, the pump assembly 2212 is a water pump 2214, and the waterway system 22 further comprises a negative pressure valve 2217 arranged between the first water inlet electromagnetic valve 2211 and the water pump 2214. It can be understood that the negative pressure valve 2217 is connected to the first water inlet electromagnetic valve 2211 and the water pump 2214 and is located 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) from being generated in the pipeline. Negative pressure can cause pipeline rupture, water hammer phenomenon (pressure impact generated 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 can prevent the generation of negative pressure in various ways, such as air supplement method, pre-pressurization method, etc. Furthermore, the negative pressure valve 2217 in the embodiments of the present application is a mechanical negative pressure valve 2217; that is, when the water tankless pipeline machine 2 is working normally, the first water inlet electromagnetic valve 2211 is opened, and the purified water filtered by the water purifier 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 related technologies, and will not be described here. Of course, in other embodiments, the pump assembly 2212 can be a flow control pump 2213, so that the negative pressure valve 2217 can not be arranged (see the accompanying drawings). The following will be described taking the pump assembly 2212 as the water pump 2214 as an example. Figure 6

[0050] Please refer to Figures 4-5 ​In some embodiments, the 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 embodiments of the present application do not make specific limitations thereon. 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, 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 flow, 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 quantity 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 under the condition of insufficient water quantity in the waterway system 22, 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 embodiments of 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 the occurrence of dry burning phenomenon, so as to protect the instant heating device 25 and ensure the safety of the water tankless pipeline machine 2, thereby achieving the protection of the water tankless pipeline machine 2. Furthermore, the water quantity sensor 2215 can achieve 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.

[0051] Please continue to refer to Figures 4-5In some embodiments, the waterway system 22 further comprises a flow meter 2216 electrically connected to the control device 24. The flow meter 2216 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. The present application does not make specific limitations on this. 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 water pump 2214 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 water pump 2214 and the flow meter 2216 stop working. In this way, 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.

[0052] Please refer to Figure 5 and Figure 8 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, 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 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.

[0053] 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.

[0054] Please continue to refer to Figure 5 and Figure 8In 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, and the present application does not make specific limitations on this.
