[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.
[0027] In the related art, a pipeline machine usually has a water tank, a heating body and a water outlet nozzle. The heating body is arranged in the water tank, and the water tank is in communication with the water outlet nozzle. When a user takes hot water, the heating body can heat the water in the water tank and then flow to the water outlet nozzle. However, the sealing property of the water outlet nozzle will be reduced due to frequent use, and water leakage will occur.
[0028] 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 and hospitals, and the present application does not make specific limitations on this.
[0029] Please refer to Figure 1 , the pure 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, 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 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.
[0030] Please continue to refer to Figure 1 In some embodiments, the pure 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 that provides 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, avoiding 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 dividing 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 dividing valve. When the user needs to take temperature-adjusted drinking water, such as 5℃-15℃ ice water in hot summer, or 40℃-50℃ warm water for washing milk powder, or 90℃-99℃ hot water for tea, 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.
[0031] Please continue to refer to 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 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 connected to the flow divider 1, so that the tap water supply pipeline can introduce tap water to the flow divider 1, regulate and maintain the excessively high and unstable water pressure of the tap water in the tap water supply pipeline within a preset pressure value range, and finally generate stabilized water and deliver 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 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.
[0032] The tankless pipeline machine 2 will be described in detail below.
[0033] Please refer to Figures 2-4 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 does not need to maintain the water temperature of the water tank, thereby reducing energy consumption and avoiding the problem of easy breeding of bacteria in the traditional tank pipeline machine, thereby improving the water quality of the tankless pipeline machine 2. The 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, 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. 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 pure water purified by 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 use by the user.
[0035] Please refer to Figures 4-5, the 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 and a pump assembly 2212 arranged in sequence along the flow direction of the water flow, the first water inlet electromagnetic valve 2211 being communicated with the water inlet 211. 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 pump assembly 2212 is responsible for providing the power of the water flow, the water pump 2214 drives the impeller to rotate by the motor to make the liquid generate centrifugal force, thereby realizing the delivery 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 realizing the adjustment of the flow of the water flow.
[0036] Please refer to Figure 2 Further, the waterway system 22 further includes a check valve 2218 arranged at the water outlet nozzle 212 to prevent the water outlet nozzle 212 from dripping. It can be understood that the waterway system 22 further includes 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 in the tankless pipeline machine 2, since the instant heating device 25 heats rapidly, it is difficult for the instant heating device 25 to heat the water in the waterway system 22 to 100 degrees Celsius, therefore, the check valve 2218 designed at the water outlet nozzle 212 in the embodiment of the 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 the water, the water outlet pipeline 29 can arrange water vapor, and since the water outlet pipeline 29 is communicated with 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.
[0037] Furthermore, the check valve 2218 can be equivalent to a one-way valve to prevent the 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.
[0038] Please refer to Figures 4-5In 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 water pump 2214, or arranged between the water outlet nozzle 212 and the water quantity sensor 2215, and the quick heating device 25 heats the water flow flowing therethrough. 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, in this way, on the one hand, the heat loss can be reduced, 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.
[0039] 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 and safety and reliability.
[0040] 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 flows 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.
[0041] Please continue to 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 and the pump assembly 2212. 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.
[0042] 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, the shell 21 is provided with a strong electric installation area 214 and a weak electric installation area, which are arranged in the length direction of the tankless pipeline machine 2, and the electric control device 24 is arranged in the weak electric installation area and the instant heating device 25 is arranged 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, in the length direction of the tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are arranged separately, so that the electromagnetic interference can be reduced to ensure the stability and reliability of the electric signal of the electric control device 24.
[0043] 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 arranged in the electric control installation area 213.
[0044] 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 and the pump assembly 2212 are arranged in the waterway installation area 2141, and the instant heating device 25 is arranged 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 heat energy interaction interference is reduced.
[0045] It should be noted that the check valve 2218 in the embodiments of the present application can be opened by electric control or mechanically; that is, the opening of the check valve 2218 is controlled by the electric control device 24, or a pressure difference is formed between the instant heating device 25 and the water outlet nozzle 212 to make the check valve 2218 open, which is not limited in the embodiments of the present application.
[0046] Please refer to Figure 4In 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 electric control installation area 213, in this way, the heat energy interaction interference is reduced.
[0047] Please continue to 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.
[0048] Please refer to Figures 4-5In 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 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. 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 under the condition of insufficient water 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 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 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.
[0049] Please refer to Figure 2 and Figure 6In some embodiments, the pump assembly 2212 is a water pump 2214, and the waterway system 22 further comprises a negative pressure valve 2217 disposed between the water inlet electromagnetic valve and the water pump 2214. It can be understood that the negative pressure valve 2217 is in communication with and 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 the pipeline to 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 achieve the purpose of preventing 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 the related art, 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 provided (see the accompanying drawings). Figure 6
[0050] Please refer to Figure 5 In some embodiments, the waterway system 22 further comprises a flow meter 2216 electrically connected with 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. It should be noted that Figure 4 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 waterway system 22 is shown in FIG. 6B. Figure 5 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 waterway system 22 is shown in FIG. 6B.
[0051] Please refer to Figures 7-8 In some embodiments, the water tankless pipeline machine 2 further comprises a sterilization device 23. The sterilization device 23 is arranged between the instant heating device 25 and the water outlet nozzle 212, or the sterilization device 23 is arranged upstream of the instant heating device 25. The present application does not make specific limitations on this. 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, etc. 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.
[0052] Please refer to Figure 3 and Figure 8In some embodiments, the tankless pipeline machine 2 further comprises an illuminating lamp 28, which is arranged on the housing 21 and faces the water storage area of the tankless pipeline machine 2, so that the light emitted by the illuminating lamp 28 illuminates the water storage area below the water outlet nozzle 212.
