[0046] The pure drinking system is mainly applied to the kitchen of the family, the tea room of the office and the like, and provides safe, healthy and convenient drinking water and domestic water for people.

[0047] The pure drinking system on the current market generally uses a water purifier as a water source, which is used for pipeline machine. However, for the instant pipeline machine, the water flow provided by the water purifier is not stable enough, and the risk of insufficient water leading to empty burning often occurs. Therefore, the pipeline machine is usually equipped with a large water tank as a buffer and water storage device, and then the water in the water tank is pumped to the heating system for instant heating by a water pump. However, this large water tank not only becomes the main obstacle to further reduce the size of the whole machine, but also easily breeds bacteria due to long-term water storage, affecting water quality safety.

[0048] The embodiment of the present application provides a pure drinking system, which comprises a water tank-free pipeline machine 2, a water purifier 3, a faucet 4 and a flow divider 1, the water purifier 3 has a raw water inlet 31 and a pure water outlet 32; the water tank-free pipeline machine 2 has a water inlet 211; the faucet 4 has a pure water inlet 41, wherein the pure water inlet 41 is directly communicated with the pure water outlet 32.

[0049] Please refer to Figure 2 andFigure 3 The shunt 1 comprises a raw water cavity 1147, a purified water cavity 1148 and a backflow cavity 1146. The shunt 1 is provided with a raw water inlet 1141, a purified water inlet 1143, a raw water outlet 1142 and a first water supply port 1144, wherein the raw water inlet 1141 is used to connect a water supply pipeline to introduce tap water into the raw water cavity 1147, the raw water outlet 1142 is used to communicate with the raw water inlet to deliver water in the raw water cavity 1147 to the water purifier 3, the purified water inlet 1143 is used to communicate with the purified water outlet 32 to introduce purified water purified by the water purifier 3, and the first water supply port 1144 is used to communicate with the water inlet 211 to deliver the purified water to the water tankless pipeline machine 2. The raw water inlet 1141 communicates with the raw water cavity 1147, the raw water outlet 1142 communicates with the backflow cavity 1146, the purified water inlet 1143 and the first water supply port 1144 both communicate with the purified water cavity 1148, and the backflow cavity 1146 communicates with the raw water cavity 1147 and the purified water cavity 1148. In this way, when the water purifier 3 delivers a large flow of water, the water in the purified water cavity 1148 can flow back to the raw water cavity 1147 through the backflow cavity 1146, and then flow to the water purifier 3 again through the raw water outlet 1142, thereby reducing the pressure of the shunt 1 and the water tankless pipeline machine 2 and improving the stability of the water purification system.

[0050] Please refer to Figure 3 The shunt 1 comprises a valve shell 11, which comprises a valve body upper shell 116 and a valve body lower shell 117 connected to each other. The valve body upper shell 116 and the valve body lower shell 117 can be assembled by connection forms including but not limited to bolt connection, clamping connection, etc. The valve body upper shell 116 and the valve body lower shell 117 jointly form the raw water cavity 1147, the backflow cavity 1146 and the purified water cavity 1148. The purified water cavity 1148 can communicate with the raw water cavity 1147 through the backflow cavity 1146. The raw water cavity 1147 and the purified water cavity 1148 are preferably located on the top side of the backflow cavity 1146. The valve body upper shell 116 is an integrally formed member, and / or the valve body lower shell 117 is an integrally formed member. Therefore, the valve shell 11 assembled by the valve body upper shell 116 and the valve body lower shell 117 is more stable and has higher structural strength. In this way, when high-pressure fluid is borne, the pressure can be evenly distributed in each part of the valve shell 11.

[0051] The shunt 1 further comprises a shunt assembly 17 arranged in the purified water cavity 1148 and separating the purified water cavity 1148 into a purified water lower cavity 11481 and a purified water upper cavity 11482. The purified water lower cavity 11481 communicates with the purified water outlet, the purified water upper cavity 11482 communicates with the purified water lower cavity 11481 and the water inlet 211, and the backflow cavity 1146 communicates with the purified water lower cavity 11481 and the raw water cavity 1147. The shunt assembly 17 can open or close the backflow cavity 1146 according to the pressure difference between the purified water lower cavity 11481 and the purified water upper cavity 11482.

[0052] The shunt assembly 17 is provided with an overflow hole, the valve housing 11 has a backflow guide portion 1171, the inside of the backflow guide portion 1171 is provided with a guide flow channel 1172 communicating with a backflow cavity 1146, the shunt assembly 17 is installed at a water outlet cavity 1148 of the valve housing 11, and the shunt assembly 17 can abut against the backflow guide portion 1171. The overflow hole is used to guide the purified water flowing from the purified water inlet 1143 to pass through the shunt assembly 17 and enter the water outlet cavity 1148. According to the pressure difference formed by the purified water inlet 1143 and the first water supply port 1144, the shunt assembly 17 can be relatively displaced towards the first water supply port 1144 side, so that the shunt assembly 17 is separated from the backflow guide portion 1171, and then the excessive purified water can flow from the guide flow channel 1172 into the backflow cavity 1146, forming the above-mentioned excess water.

[0053] The existing pipeline machine needs to be provided with a water tank, and the volume is relatively large. Therefore, the application provides a water tank-free pipeline machine 2 which is small in volume and compact in structure. Next, the water tank-free pipeline machine 2 will be described in detail.

[0054] The water tank-free pipeline machine 2 includes a housing 21, a waterway system 22, an instant heating device 25, and a water outlet pipeline 29.

[0055] The housing 21 has a water inlet 211 and a water outlet 212. The housing 21 can include a first shell and a second shell which can be detachably connected by clamping, screw connection or the like. The first shell and the second shell enclose an installation cavity 215. The waterway system 22, the instant heating device 25 and the water outlet pipeline 29 are all installed in the installation cavity 215. The waterway system 22 is used to supply water to the instant heating device 25. The water tank-free pipeline machine 2 further includes an electric control device 24 which is used to control the working conditions of the waterway system 22 and the instant heating device 25. Through preset programs and algorithms, the electric control device 24 can accurately adjust the water flow rate, water temperature and other parameters to meet different needs of users.

[0056] It should be noted that the water inlet 211 and the water outlet 212 can be in the form of a pipeline integrally formed on the housing 21, or in the form of separate components such as a hose or a connector. The first shell and / or the second shell is formed with a clearance, and the water inlet 211 and / or the water outlet 212 component can at least partially extend into the installation cavity 215 through the clearance and be connected to other components in the installation cavity 215.

[0057] 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 installation cavity 215 includes a strong current installation area 214 and a weak current installation area, and the strong current installation area 214 is arranged apart from the weak current installation area in the length direction of the tankless pipeline machine 2, wherein the electric control device 24 is installed in the strong current installation area 214, and the instant heating device 25 is installed in the weak current installation area. It can be understood that the instant heating device 25 needs to be powered by strong current, and the strong current has the characteristics of high voltage and large current; the electric control device 24 needs to be powered by weak current, and the weak current has the characteristics of low voltage and small current, so the electric control device 24 and the instant heating device 25 are arranged apart 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 power-on signal of the electric control device 24.

[0058] Further, the strong current installation area 214 includes a waterway installation area 2141 and an instant heating installation area 2142 arranged in sequence in the length direction, and the electric control installation area 213 and the instant heating installation area 2142 are respectively located on both sides of the waterway installation area 2141, so as to avoid unnecessary heat transfer superposition between the electric control device 24 and the instant heating device 25. It can be understood that the instant heating device 25 needs to be powered by strong current, and the strong current has the characteristics of high voltage and large current; the electric control device 24 needs to be powered by weak current, and the weak current has the characteristics of low voltage and small current, so the electric control device 24 and the instant heating device 25 are arranged apart 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 power-on signal of the electric control device 24.

[0059] The waterway system 22 includes a first water inlet electromagnetic valve 2211 and a pump assembly 2212, the first water inlet electromagnetic valve 2211 is in communication with the water inlet 211, and the first water inlet electromagnetic valve 2211 and the pump assembly 2212 are arranged side by side in the length direction in the waterway installation area 2141; the water inlet end of the instant heating device 25 is in communication with the water outlet end of the pump assembly 2212; the water inlet end of the water outlet pipeline 29 is in communication with the water outlet end of the instant heating device 25, and the instant heating device 25 and the water outlet pipeline 29 are arranged side by side in the thickness direction of the shell 21 in the instant heating installation area 2142.

[0060] Based on the tankless pipeline machine 2 of the embodiments of the present application, since it is designed without a water tank, it does not occupy too much space, the overall volume of the pipeline machine is more compact, and it can be installed in a smaller area, and the installation is more flexible; and 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, which reduces energy consumption, and also avoids the problems of easy dirt accumulation, serious odor, bacterial breeding and the like in the traditional water tank, ensures the purity of the outlet water, and improves the quality of drinking water.

[0061] Since the water tank is not provided, the waterway system 22 needs to be provided with a first water inlet electromagnetic valve 2211 and a pump assembly 2212. The first water inlet electromagnetic valve 2211 is responsible for controlling the on-off of water flow, and the pump assembly 2212 is responsible for providing power for water flow. It can be understood that the first water inlet electromagnetic valve 2211 and the pump assembly 2212 have a large volume. The first water inlet electromagnetic valve 2211 and the pump assembly 2212 are arranged side by side in the length direction of the shell 21. The instant heating device 25 and the water outlet pipeline 29 have a small volume. The instant heating device 25 and the water outlet pipeline 29 are arranged side by side in the thickness direction of the shell 21. The first water inlet electromagnetic valve 2211 and the pump assembly 2212 are arranged in the waterway mounting area 2141, and the instant heating device 25 and the water outlet pipeline 29 are arranged in the instant heating mounting area 2142. The installation layout provided by the present application can separate the waterway system 22 and the instant heating device 25, avoid the heat generated by the operation of the instant heating device 25 from affecting the equipment operation of the waterway system 22, make the structure inside the whole shell 21 compact, save space, and be conducive to the miniaturization and light weight of the equipment. For example, if the water outlet pipeline 29 and the instant heating device 25 are arranged side by side in the length direction of the shell 21, the length of the shell 21 is likely to be longer. The installation layout can also facilitate the equipment maintenance or maintenance of the waterway system 22.

[0062] It should be noted that the first shell and the second shell are fixedly connected in the horizontal direction. After the first shell is disassembled, the equipment of the waterway system 22 and the instant heating device 25 are arranged side by side in the second shell. In this way, the internal equipment can be seen at a glance, which is convenient for maintenance or replacement.

[0063] In some embodiments, the pump assembly 2212 can include a flow control pump 2213 and a water pump 2214. When the pump assembly 2212 includes the water pump 2214, the waterway system 22 further includes a negative pressure valve 2217. The negative pressure valve 2217 is arranged in the waterway mounting area 2141 and communicates between the first water inlet electromagnetic valve 2211 and the water pump 2214. 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 or at least prevent negative pressure from being generated in the pipeline, thereby protecting the water pump 2214 and other components in the waterway system 22 from being damaged. There are various ways for the negative pressure valve 2217 to prevent negative pressure from being generated, such as air supplement method, pre-pressurization method, etc. The specific structure and principle of the negative pressure valve 2217 have been disclosed in related technologies, and will not be described herein.

[0064] Of course, when the pump assembly 2212 is a flow control pump 2213, the negative pressure valve 2217 can not be provided. The flow control pump 2213 is a pump capable of maintaining constant pressure when the flow changes. The flow control pump 2213 can stabilize the fluid state in the delivery pipeline by precisely controlling the flow and pressure of the water flow. In some cases, when the water flow in the delivery pipeline is cut off, the flow control pump 2213 can adjust its output flow to keep the fluid pressure in the pipeline within a stable range, thereby avoiding the occurrence of negative pressure.

[0065] In some embodiments, the waterway system 22 further comprises a water volume sensor 2215 installed in the waterway installation area 2141, which can be arranged between the water inlet 211 and the first water inlet electromagnetic valve 2211, or between the first water inlet electromagnetic valve 2211 and the water pump 2214, or between the water pump 2214 and the instant heating device 25. The instant heating device 25 is configured to reduce power or stop working when the value detected by the water volume sensor 2215 is lower than a preset value. The water volume sensor 2215 can monitor the water volume in the waterway system 22 in real time, stop or reduce the power of the instant heating device 25 in time when the water volume is insufficient, prevent the occurrence of dry burning phenomenon, and protect the safety of the equipment. By intelligently controlling the power of the instant heating device 25, the water volume sensor 2215 can achieve the effect of energy saving and power saving, and reduce the electricity cost of the user.

[0066] In some embodiments, the waterway system 22 further comprises a flow meter 2216 installed in the waterway installation area 2141, wherein the flow meter 2216 can be arranged between the water inlet 211 and the first water inlet electromagnetic valve 2211, or between the first water inlet electromagnetic valve 2211 and the water pump 2214, or between the water pump 2214 and the instant heating device 25. The flow meter 2216 is used to measure the flow of water flow, and provide accurate water consumption data for the user. By statistically analyzing the data collected by the flow meter 2216, the user can understand the water consumption law of the tankless pipeline machine 2.

[0067] In some embodiments, the first water inlet electromagnetic valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216 and the water pump 2214 are sequentially communicated in the flow direction of the water flow; the first water inlet electromagnetic valve 2211 and the negative pressure valve 2217 are arranged at intervals in the height direction of the shell 21, the water volume sensor 2215, the flow meter 2216 and the water pump 2214 are arranged at intervals in the height direction of the shell 21 and are located between the whole formed by the first water inlet electromagnetic valve 2211 and the negative pressure valve 2217 and the whole formed by the instant heating device 25 and the water outlet pipeline 29, and the water pump 2214 is located below the water volume sensor 2215 and the flow meter 2216. The components such as the first water inlet electromagnetic valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216 and the water pump 2214 are divided into zones according to functions, so that the role of each part is more clear. When a fault occurs, the problem can be quickly located, and maintenance and repair are facilitated.

[0068] Please refer to Figure 3 and Figure 4 In some embodiments, the shell 21 includes a housing 216 and a mounting bracket 217, wherein the housing 216 includes the first shell and the second shell described above and has a mounting cavity 215; the mounting bracket 217 is fixedly connected with the housing 216 and is fixed in the mounting cavity 215, and the first water inlet electromagnetic valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216 and the water pump 2214 are all mounted on the mounting bracket 217. In this way, the various parts can be first mounted on the mounting bracket 217, and then the mounting bracket 217 is mounted in the mounting cavity 215, so that the assembly process is more simple and fast, and the installation difficulty and cost are reduced. When a part fails or needs to be maintained, the mounting bracket 217 can be taken out as a whole, so that the waterway system 22 can be taken out to observe the position of the fault, facilitating replacement and maintenance of parts.

[0069] In some embodiments, the tankless pipeline machine 2 further includes a sterilization device 23 arranged on the water outlet pipeline 29 and sterilizing the water of the water outlet pipeline 29. 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 chemical residues, thereby reducing pollution to the environment. The sterilization device 23 can effectively kill bacteria, viruses and other microorganisms in the water outlet pipeline 29, ensuring the safety and hygiene of the water quality and effectively reducing health problems caused by water quality problems.

[0070] In some embodiments, the water outlet nozzle 212 is arranged at the bottom of the shell 21; that is, the water inlet end of the instant heating device 25 is below the instant heating device 25, and the water outlet end is above the instant heating device 25. Specifically, the water outlet nozzle 212 is located at the bottom of the shell 21, which is convenient for users to take water, especially for low space or children. Moreover, the water inlet end and the water outlet end of the instant heating device 25 are arranged below and above, respectively, which can improve the utilization of space. In detail, since the water outlet nozzle 212 is arranged at the bottom of the shell 21, the water outlet of the water outlet pipeline 29 is provided with the sterilization device 23, and considering the parallel arrangement of the water outlet pipeline 29 and the instant heating device 25, the water inlet end of the water outlet pipeline 29 is arranged above, so that the water inlet end and the water outlet end of the instant heating device 25 are arranged below and above, respectively, thereby adapting to the arrangement of the water outlet pipeline 29.

[0071] The arrangement of the waterway system 22 described above is also adapted to the waterway of the instant heating installation area 2142. Specifically, the water inlet 211 is arranged at the bottom of the shell 21, the first water inlet electromagnetic valve 2211 and the negative pressure valve 2217 are arranged at intervals in the height direction, the water quantity sensor 2215, the flow meter 2216 and the water pump 2214 are also arranged at intervals in the height direction, and the water from the water source enters the waterway system 22 from the water inlet 211, first passes through the first water inlet electromagnetic valve 2211 and the negative pressure valve 2217, at this time the water flows upward, then passes through the water quantity sensor 2215, the flow meter 2216 and the water pump 2214, at this time the water flows downward, then enters the instant heating device 25, flows upward again, then passes through the water outlet pipeline 29 and flows downward, and finally flows out from the water outlet nozzle 212.

[0072] In the present application, through reasonable layout of parts, the space in the shell 21 can be fully utilized, the device as a whole is more compact, the water flow can be smoothly and efficiently heated, and the parts inside the device can be easily maintained and repaired, thereby improving the practicability of the tankless pipeline machine 2.

[0073] In the present application, the first water inlet electromagnetic valve 2211, the flow control pump 2213, the water quantity sensor 2215 and the flow meter 2216 are 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, thereby reducing the thermal energy interaction interference.

[0074] In some embodiments, the waterway system 22 further comprises a check valve 2218 arranged on the water outlet nozzle 212 and preventing the water flow from flowing backward in the pipeline, thereby protecting other components in the waterway system 22, such as the water pump 2214, the instant heater 25, etc., from being impacted and damaged by the reverse water flow. When the instant heater 25 is used to heat the water in the waterway system 22 in the tankless pipeline machine 2, it is difficult for the instant heater 25 to heat the water in the waterway system 22 to 100 degrees Celsius due to the rapid heating of the instant heater 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 the 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.

[0075] In some embodiments, the tankless pipeline machine 2 further comprises an illuminating lamp 28 arranged on the housing 21 and facing 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. The illuminating lamp 28 can illuminate the water storage area, so that the user can clearly see the water level, water quality, and whether there are impurities in the water storage container even in a relatively dark environment, thereby ensuring the accuracy and safety of water taking. In addition, the light of the illuminating lamp 28 helps the user to more intuitively check the cleaning degree of the water storage area and the water outlet nozzle 212, thereby reminding the user to clean and maintain in time and ensuring the water hygiene.

[0076] 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. The display device 27 can display the working state of the tankless pipeline machine 2 in real time and intuitively, such as the water temperature, the working state (heating, water outlet, standby, etc.), and possible fault prompts, etc., so that the user can better master the working condition of the device, thereby reasonably arranging the use time and frequency and avoiding unnecessary energy waste. For example, when the water temperature is relatively low, the required heating time is relatively long, and the user can arrange other work in advance, thereby avoiding the waste of time due to waiting for the water temperature to rise.

[0077] In some embodiments, the display device 27 and the illuminating lamp 28 are both installed in the instant heater installation area 2142, so that the display device 27 and the illuminating lamp 28 are close to each other. Since the display device 27 and the illuminating lamp 28 are close to each other, the display device 27 is electrically connected with the illuminating lamp 28 in the embodiments of the present application, and the display device 27 is further used to supply power to the illuminating lamp 28 and directly control the opening and closing of the illuminating lamp 28, which helps to simplify the wiring complexity in the tankless pipeline machine 2.
