Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pure drinking equipment, especially relates to a pure drinking system. BACKGROUND

[0002] The pure drinking system is mainly applied to the kitchen of a family, the tea room of an office and the like, and provides safe, healthy and convenient drinking water and domestic water for people.

[0003] The current pure drinking system mainly supplies the pipeline machine with the purified water generated by the water purifier. The current pure drinking system is mainly designed to supply the pipeline machine with the water purified by the water purifier, but the function of the pipeline machine is often limited to providing hot water or cold water. When a user wants to obtain normal-temperature water, such a system often cannot directly meet the demand of the user. Since the pipeline machine usually does not have the function of adjusting the water temperature to the normal temperature, the user may encounter inconvenience in drinking the normal-temperature water. Therefore, for the user who pursues more diversified drinking water demand, the current pure drinking system has certain limitation in flexibility. SUMMARY

[0004] The embodiment of the present application provides a pure drinking system which can meet different demands of users.

[0005] The embodiment of the present application provides a pure drinking system, which comprises a water purifier, a pipeline machine without a water tank and a flow divider. The water purifier has a raw water inlet and a purified water outlet. The pipeline machine without the water tank comprises a shell, a hot water circuit and a normal-temperature water circuit. The shell has a water inlet and a water outlet nozzle. The hot water circuit is arranged in the shell and located between the water inlet and the water outlet nozzle. The hot water circuit comprises a first water inlet electromagnetic valve and a pump assembly arranged in sequence along the flow direction of water flow. The normal-temperature water circuit is provided with a second water inlet electromagnetic valve. The water inlet end of the normal-temperature water circuit is communicated with the water inlet, and the water outlet end is communicated with the hot water circuit and located downstream of the pump assembly. The flow divider is provided with an inlet cavity communicated with a water source and the raw water inlet, an outlet cavity communicated with the purified water outlet and the water inlet, and a reflux cavity communicated with the outlet cavity and the inlet cavity.

[0006] In some embodiments, the pump assembly comprises a water pump or a flow control pump. When the pump assembly comprises the water pump, the hot water circuit further comprises:

[0007] A negative pressure valve is communicated with and located between the first water inlet electromagnetic valve and the water pump.

[0008] In some embodiments, the hot water circuit further comprises:

[0009] A water amount sensor is arranged between the water inlet and the first water inlet electromagnetic valve, or arranged between the first water inlet electromagnetic valve and the pump assembly, or arranged between the pump assembly and the connection between the outlet end of the normal temperature water path and the hot water path.

[0010] In some embodiments, the hot water path further comprises:

[0011] A flow meter is arranged in the hot water path and located downstream of the connection between the outlet end of the normal temperature water path and the hot water path.

[0012] In some embodiments, the tankless pipeline machine further comprises:

[0013] A instant heating device is connected to the hot water path and located downstream of the connection between the outlet end of the normal temperature water path and the hot water path.

[0014] In some embodiments, the tankless pipeline machine further comprises:

[0015] A sterilization device is arranged between the instant heating device and the water outlet nozzle, or arranged between the instant heating device and the connection between the outlet end of the normal temperature water path and the hot water path.

[0016] In some embodiments, the hot water path further comprises:

[0017] A check valve is arranged at the water outlet nozzle to prevent water dripping from the water outlet nozzle.

[0018] In some embodiments, the tankless pipeline machine further comprises:

[0019] An irradiation lamp is arranged on the housing and directed towards a water containing area of the tankless pipeline machine, so that light emitted by the irradiation lamp irradiates the water containing area which is located below the water outlet nozzle.

[0020] In some embodiments, the tankless pipeline machine further comprises:

[0021] A display device is arranged on the housing to display working information of the tankless pipeline machine.

[0022] In some embodiments, the tankless pipeline machine further comprises:

[0023] A faucet has a pure water inlet which is connected to the pure water outlet.

[0024] In some embodiments, the tankless pipeline machine further comprises:

[0025] A faucet has a pure water inlet.

[0026] The water outlet chamber includes a lower water outlet chamber that connects the water inlet chamber and the pure water outlet, and an upper water outlet chamber that connects the lower water outlet chamber and the water inlet, wherein the reflux chamber connects the lower water outlet chamber and the water inlet chamber.

[0027] Based on the water purification system of this application embodiment, the water purifier supplies water to the tankless water dispenser through a distributor. The distributor is equipped with a return chamber, so that when the water purifier delivers a large flow of water, the water in the outlet chamber can flow back to the inlet chamber through the return chamber and then flow back to the water purifier, reducing the pressure burden on the distributor and the tankless water dispenser, thereby enhancing the stability of the entire water purification system. The tankless water dispenser is equipped with a hot water circuit and a normal temperature water circuit. The hot water circuit is equipped with a first inlet solenoid valve and a pump assembly. Due to the pump assembly, the water flow rate of the hot water circuit is relatively small, but sufficient to meet the immediate daily hot water needs. The normal temperature water circuit cleverly bypasses the pump assembly and directly controls the flow through a second inlet solenoid valve, allowing for a relatively larger water flow rate, fully meeting the needs of high-volume water usage scenarios and satisfying different user requirements.

The terms used in the specification of the present description are only for the purpose of describing the specific embodiments, and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0048] Please refer to Figure 1 The application embodiment proposes a kind of pure drinking system, including water purifier 3, water tankless pipeline machine 2, faucet 4 and flow divider 1, water purifier 3 has raw water inlet 31 and pure water outlet 32;Water tankless pipeline machine 2 has water inlet 211;Faucet 4 has pure water inlet 41.

[0049] Please refer to Figures 2 to 5The tankless pipeline machine 2 comprises a housing 21, a water system 22, a heating device 25, and a water outlet pipe 29. The housing 21 has a water inlet 211 and a water outlet 212. The housing 21 can comprise a first housing and a second housing, which can be detachably connected by clamping, screwing, or the like. The first housing and the second housing enclose a mounting cavity 215. The water system 22, the heating device 25, and the water outlet pipe 29 are all mounted in the mounting cavity 215. The water system 22 supplies water to the heating device 25. The tankless pipeline machine 2 further comprises an electric control device 24, which controls the working conditions of the water system 22 and the heating device 25. Through preset programs and algorithms, the electric control device 24 can accurately adjust the water flow rate, water temperature, and the like to meet different needs of users.

[0050] It should be noted that the water inlet 211 and the water outlet 212 can be in the form of a pipe integrally formed on the housing 21, or in the form of a separate component, such as a hose or a connector. The first housing and / or the second housing has a relief opening, and the water inlet 211 and / or the water outlet 212 component can at least partially extend into the mounting cavity 215 through the relief opening and be connected to other components in the mounting cavity 215.

[0051] In order to optimize the heat management of the tankless pipeline machine 2 and avoid unnecessary heat transfer and superposition between the electric control device 24 and the heating device 25, please refer to Figure 3 and Figure 4 In some embodiments, the mounting cavity 215 comprises a strong electric mounting area 214 and a weak electric mounting area, which are arranged in the length direction of the tankless pipeline machine 2. The electric control device 24 is mounted in the strong electric mounting area 214, and the heating device 25 is mounted in the weak electric mounting area. The strong electric mounting area 214 is also an electric control mounting area 213 for mounting the electric control device 24. It can be understood that the heating device 25 needs strong electric power supply, and the strong electric power has high voltage and large current characteristics. The electric control device 24 needs weak electric power supply, and the weak electric power has low voltage and small current characteristics. Therefore, the electric control device 24 and the heating device 25 are arranged in the length direction of the tankless pipeline machine 2. In this way, the electromagnetic interference can be reduced to ensure the stability and reliability of the electric signal on the electric control device 24.

[0052] Further, please refer to Figure 3 and Figure 4, 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 that unnecessary heat transfer superposition between the electric control device 24 and the instant heating device 25 can be avoided. 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. Therefore, the electric control device 24 and the instant heating device 25 are arranged separately in the length direction of the water tankless pipeline machine 2, so that electromagnetic interference can be reduced to ensure the stability and reliability of the power signal of the electric control device 24.

[0053] Please refer back to Figure 1 , the waterway system 22 includes a hot waterway 221 and a normal temperature waterway 222, the hot waterway 221 is used to provide hot water, and the normal temperature waterway 222 is used to provide normal temperature water. The hot waterway 221 includes a first water inlet electromagnetic valve 2211 and a pump assembly 2212, and the first water inlet electromagnetic valve 2211 is in communication with the water inlet 211. The water inlet of the normal temperature waterway 222 is in communication with the water inlet 211, the water outlet is in communication with the hot waterway 221 and is located downstream of the pump assembly 2212, and the normal temperature waterway 222 is provided with a second water inlet electromagnetic valve 2221. Specifically, since the hot waterway 221 is provided with a water pump 2214, the water flow of the hot waterway 221 is relatively small, but it is sufficient to meet the instant demand of daily hot water. The normal temperature waterway 222 skillfully bypasses the pump assembly 2212 and directly controls the opening and closing of the waterway through the second water inlet electromagnetic valve 2221, so that the water flow can be relatively increased, and the use scene of large water flow can be fully met. In addition, even when the instant heating device 25 does not start heating hot water, normal temperature water will still continuously flow through the instant heating device 25, not only maintaining the dynamic circulation of the waterway of the instant heating device 25, but also significantly reducing the risk of bacterial breeding, and ensuring the health and safety of water use.

[0054] Please refer back to Figure 3 and Figure 4 , in order to facilitate the installation of the hot waterway 221 in the shell 21, 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. Further, the normal temperature waterway 222 can also be installed in the waterway installation area 2141, and the second water inlet electromagnetic valve 2221 can be arranged side by side with the first water inlet electromagnetic valve 2211 in the length direction in the waterway installation area 2141, or can be arranged side by side in the height direction in the waterway installation area 2141, which is not limited in the present application.

[0055] The water tankless pipeline machine 2 based on the embodiments of the present application does not occupy too much space because it is designed without a water tank, and the overall volume of the pipeline machine is smaller, which can be installed in a smaller area and is more flexible to install. Moreover, because the water 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 avoids the problems of dirt accumulation, serious odor and bacterial growth in the traditional water tank, thereby ensuring the purity of the water and improving the quality of the drinking water.

[0056] Because it is designed without a water tank, the hot water waterway 221 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 the water flow, and the pump assembly 2212 is responsible for providing power for the 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, and the water outlet pipeline 29 has 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, and 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 and the water outlet pipeline 29 are arranged in the instant heating installation area 2142. The installation layout provided by the present application can first separate the waterway system 22 and the instant heating device 25, so as to avoid the influence of the heat generated by the operation of the instant heating device 25 on the equipment operation of the waterway system 22. Second, the structure inside the entire shell 21 is compact, which saves space and is beneficial 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 will be longer. Third, the equipment maintenance or repair of the waterway system 22 can be considered.

[0057] It should be noted that the first shell and the second shell are fixedly connected in the horizontal direction, and 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. When installed and used, the second shell is hung on the wall surface, so that the water tankless pipeline machine 2 does not need to be taken down as a whole, and the maintenance or repair of the parts in the installation cavity 215 can be directly performed after the first shell is disassembled. Further, based on the installation environment, the back of the water tankless pipeline machine 2 is attached to the wall surface, the second shell can be in the form of a cover shell with an open front side, and the first shell forms a cover structure and covers the opening.

[0058] Please refer to Figures 7 to 9In 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 disposed in the waterway installation area 2141. The negative pressure valve 2217 is connected 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 occurring in the pipeline. Negative pressure can cause the pipeline to rupture, water hammer (pressure impact caused by 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 occurrence of negative pressure, thereby protecting the water pump 2214 and other components in the waterway system 22 from damage. The negative pressure valve 2217 can prevent the occurrence of negative pressure in various ways, such as air supplementing method, pre-pressurization method, etc. The specific structure and principle of the negative pressure valve 2217 are well known in the related art, and will not be described here.

[0059] 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 that can maintain 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 maintain the fluid pressure in the pipeline within a stable range, thereby avoiding the occurrence of negative pressure.

[0060] Referring to Figures 7 to 9 In some embodiments, the hot water waterway 221 further includes a flow meter 2216 installed in the waterway installation area 2141. The flow meter 2216 can be disposed 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 to provide accurate water usage data to the user. By statistically analyzing the data collected by the flow meter 2216, the user can understand the water usage pattern of the tankless pipeline machine 2.

[0061] Referring to Figures 7 to 9In some embodiments, the hot water channel 221 further comprises a water amount sensor 2215 installed in the water channel 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 amount sensor 2215 is lower than a preset value. The water amount sensor 2215 can monitor the water amount in the water channel system 22 in real time, stop or reduce the power of the instant heating device 25 in time when the water amount 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 amount sensor 2215 can achieve the effect of energy saving and power saving, and reduce the electricity cost of the user.

[0062] Referring to Figures 7 to 9 In some embodiments, in the flow direction of the water flow, the first water inlet electromagnetic valve 2211, the negative pressure valve 2217, the water amount sensor 2215, the flow meter 2216, and the water pump 2214 are sequentially communicated; wherein 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 amount sensor 2215, the flow meter 2216, and the water pump 2214 are arranged at intervals in the height direction of the shell 21 and 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 amount 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 amount sensor 2215, the flow meter 2216, and the water pump 2214 are partitioned according to functions, so that the role of each part is more explicit. When a fault occurs, the problem can be quickly located, and maintenance and repair are facilitated.

[0063] Referring to Figure 3 and Figure 4In some embodiments, the shell 21 comprises an outer shell 216 and a mounting frame 217, wherein the outer shell 216 comprises the first shell and the second shell described above and has the mounting cavity 215; the mounting frame 217 is fixedly connected with the outer shell 216 and is fixed in the mounting cavity 215; 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 frame 217. In this way, the various components can be mounted on the mounting frame 217 first, and then the mounting frame 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 component fails or needs to be maintained, the mounting frame 217 can be taken out as a whole, so that the water system 22 can be taken out to observe the position of the fault, facilitating the replacement and maintenance of the components.

[0064] Referring to Figure 6 In some embodiments, the tankless pipeline machine 2 further comprises a sterilization device 23 arranged on the water outlet pipeline 29 and sterilizing the water in the water outlet pipeline 29. The sterilization device 23 can be in the form of an ultraviolet sterilizer or an ozone sterilizer, etc. Such a sterilization device 23 can effectively sterilize without generating 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.

[0065] Referring to Figures 2 to 4 and Figure 6 In some embodiments, the water outlet nozzle 212 is arranged at the bottom of the shell 21; the water inlet end of the instant heating device 25 is located below the instant heating device 25, and the water outlet end is located 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. The water inlet end and the water outlet end of the instant heating device 25 are located below and above, respectively, which can improve the utilization rate of space. In detail, since the water outlet nozzle 212 is located 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 located below and above, respectively, thereby adapting to the arrangement of the water outlet pipeline 29.

[0066] The arrangement of the waterway system 22 described above is also suitable for the waterway layout in 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 volume sensor 2215, the flow meter 2216 and the water pump 2214 are also arranged at intervals in the height direction. After the water from the water source enters the waterway system 22 through the water inlet 211, it first passes through the first water inlet electromagnetic valve 2211 and the negative pressure valve 2217, at which time the water flows upward, then passes through the water volume sensor 2215, the flow meter 2216 and the water pump 2214, at which time the water flows downward, then enters the instant heating device 25, flows upward again, then flows downward through the water outlet pipeline 29, and finally flows out from the water outlet nozzle 212.

[0067] In the present application, by reasonable layout of parts, the space in the shell 21 can be fully utilized, so that the whole device is more compact, the water flow can be smoothly and efficiently heated, and the internal parts of the device can be easily maintained and repaired, thereby improving the practicability of the water tankless pipeline machine 2.

[0068] In the present application, the first water inlet electromagnetic valve 2211, the flow control pump 2213, the water volume 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 water 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 water 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.

[0069] Please refer to Figure 6 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 and the instant heating device 25, from being impacted and damaged by the reverse water flow. When the instant heating device 25 is used to heat the water in the waterway system 22 in the water tankless pipeline machine 2, 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 designed at the water outlet nozzle 212 in the present application can function as a pressure bearing to increase the boiling point of the water in the water outlet pipeline 29, so that the water boils, and water vapor can be arranged in the water outlet pipeline 29 during the boiling process. 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.

[0070] Please refer to Figure 2 and Figure 6 In some embodiments, the tankless pipeline machine 2 further comprises an illuminating lamp 28 arranged on the shell 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 water hygiene.

[0071] Please refer to Figure 4 In some embodiments, the tankless pipeline machine 2 further comprises a display device 27 arranged on the shell 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 water temperature, working state (heating, water outlet, standby, etc.), and possible fault prompt, 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.

[0072] In some embodiments, the display device 27 and the illuminating lamp 28 are both installed in the instant heating installation area 2142, so that the display device 27 and the illuminating lamp 28 can be arranged close to each other. Since the display device 27 and the illuminating lamp 28 are arranged 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 for supplying power to the illuminating lamp 28 and directly controlling the opening and closing of the illuminating lamp 28, which helps to simplify the wiring complexity in the tankless pipeline machine 2.

[0073] In some embodiments, the water purification system further comprises a faucet 4, wherein the faucet 4 can be directly connected to the water purifier 3 to directly supply the purified water of the water purifier 3 to the user. The faucet 4 can also be connected to the water outlet cavity 1148 of the shunt 1, thereby providing the purified water of the water purifier 3 to the user. In this way, the water purifier 3 can only provide one pure water outlet 32, and the shunt 1 capable of being connected to the tankless pipeline machine 2 and the faucet 4 will be introduced next.

[0074] It can be understood that the amount of water purified by the water purifier 3 is relatively large, and the amount of water used by the tankless pipeline machine 2 is relatively small due to the heating efficiency of the instant heating device 25. When the water pressure in the water outlet cavity 1148 is relatively large, the water can be returned to the water inlet cavity 1147 through the return cavity 1146, thereby improving the service life of the shunt 1 and the tankless pipeline machine 2.

[0075] Referring to Figures 10 to 12 , the shunt 1 comprises a water inlet cavity 1147, a water outlet 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 water inlet cavity 1147, the raw water outlet 1142 is used to communicate with the raw water inlet 31 to deliver water in the water inlet 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 water inlet 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 water outlet cavity 1148, and the backflow cavity 1146 communicates with the water inlet cavity 1147 and the water outlet cavity 1148. In this way, when the water purifier 3 delivers a large flow of water, the water in the water outlet cavity 1148 can flow back to the water inlet 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 clean drinking system.

[0076] Referring to Figures 10 to 12 , the shunt 1 comprises a valve shell 11, the valve shell 11 comprises a valve body upper shell 116 and a valve body lower shell 117 connected to each other, and the valve body upper shell 116 and the valve body lower shell 117 can be assembled in a connection form including but not limited to bolt connection, clamping connection and the like. The valve body upper shell 116 and the valve body lower shell 117 jointly configure the water inlet cavity 1147, the backflow cavity 1146 and the water outlet cavity 1148, the water outlet cavity 1148 can communicate with the water inlet cavity 1147 through the backflow cavity 1146, the water inlet cavity 1147 and the water outlet cavity 1148 are preferably located at the top side of the backflow cavity 1146, and the valve body upper shell 116 is an integrally formed component, and / or the valve body lower shell 117 is an integrally formed component, so that 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. Preferably, the raw water outlet 1142, the purified water inlet 1143 and the second water supply port 1145 are all arranged on the valve body lower shell 117, and the raw water inlet 1141 and the first water supply port 1144 are arranged on the valve body upper shell 116.

[0077] Referring to Figures 10 to 12The shunt 1 further comprises a shunt assembly 17 arranged in the water outlet cavity 1148 and separating the water outlet cavity 1148 into a lower water outlet cavity 11481 and an upper water outlet cavity 11482, wherein the lower water outlet cavity 11481 is communicated with the pure water outlet 32 and the pure water inlet 41, the upper water outlet cavity 11482 is communicated with the lower water outlet cavity 11481 and the water inlet 211, and the reflux cavity 1146 is communicated with the lower water outlet cavity 11481 and the water inlet cavity 1147. The shunt assembly 17 can open or close the reflux cavity 1146 according to the pressure difference between the lower water outlet cavity 11481 and the upper water outlet cavity 11482.

[0078] The shunt assembly 17 is provided with a flow hole, the valve housing 11 has a reflux guide portion 1171, the reflux guide portion 1171 is internally provided with a guide flow channel 1172 communicated with the reflux cavity 1146, the shunt assembly 17 is installed in the water outlet cavity 1148 of the valve housing 11 and can abut against the reflux guide portion 1171, and the flow hole is used to guide the pure water flowing from the pure 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 pure water inlet 1143, the first water supply port 1144 and the second water supply port 1145, the shunt assembly 17 can relatively displace towards the first water supply port 1144 side, so that the shunt assembly 17 is separated from the reflux guide portion 1171, and then the excessive pure water can flow from the guide flow channel 1172 into the reflux cavity 1146 to form the above-mentioned excessive water.

[0079] When the faucet 4 is used for water alone, the pure water flows from the pure water inlet 1143 into the valve housing 11 and directly flows out from the second water supply port 1145, at this time, the shunt assembly 17 abuts and fits on the reflux guide portion 1171 to seal the guide flow channel 1172, so that the pure water cannot reflux to the guide flow channel 1172.

[0080] When the tankless pipeline machine 2 uses water alone, the purified water flows into the valve housing 11 from the purified water inlet 1143, and then enters the water outlet cavity 1148 through the water hole, and finally flows out from the first water outlet 1144 to the tankless pipeline machine 2. At this time, the pressure on the side of the shunt assembly 17 close to the first water outlet 1144 is less than the pressure on the side of the shunt assembly 17 away from the first water outlet 1144, that is, the water pressure formed by the purified water inlet 1143 and the second water outlet 1145 is greater than the water pressure on the side of the first water outlet 1144. The shunt assembly 17 can produce relative displacement towards the side of the first water outlet 1144, so that the shunt assembly 17 is separated from the backflow guide part 1171, and the excess purified water flows back to the guide flow channel 1172. When the tankless pipeline machine 2 is closed, the shunt assembly 17 will be reset towards the side of the backflow guide part 1171, and then the shunt assembly 17 abuts against the backflow guide part 1171 again to reseal the guide flow channel 1172. Therefore, the shunt 1 can flexibly cope with the water distribution requirements when the tankless pipeline machine 2 uses water alone, so that the purified water can meet the water demand of the tankless pipeline machine 2 while reasonably handling the excess water, so as to avoid waste of water resources and the risk of damage to the tankless pipeline machine 2 due to excessive water pressure.

[0081] When the tankless pipeline machine 2 and the faucet 4 use water at the same time, part of the purified water flows out from the second water outlet 1145 to the faucet 4 after flowing into the valve housing 11 from the purified water inlet 1143, and the other part enters the water outlet cavity 1148 through the water hole and flows out from the first water outlet 1144 to the tankless pipeline machine 2. Because the water pressure on the side of the second water outlet 1145 is reduced, the pressure on the side of the shunt assembly 17 close to the first water outlet 1144 is not much different from the pressure on the side of the shunt assembly 17 away from the first water outlet 1144. At this time, the shunt assembly 17 abuts against the backflow guide part 1171, so that the excess purified water will not flow back to the guide flow channel 1172. In this way, the tankless pipeline machine 2 and the faucet 4 can both use water normally, and the stable operation of the entire purified drinking system is ensured.

[0082] Thus, because the excess purified water can flow back when the tankless pipeline machine 2 is turned on, the purified water machine 3 can avoid frequent adjustment of its working state due to sudden changes in water consumption of the tankless pipeline machine 2 (such as water pressure changes caused by frequent opening and closing of the tankless pipeline machine 2). For example, without the backflow mechanism, when the tankless pipeline machine 2 is suddenly turned off, the instantaneous change in water pressure can cause an impact on the internal structure and working pressure of the purified water machine 3, and with the backflow mechanism, the water pressure change can be buffered to some extent, reducing the pressure on the purified water machine 3 to frequently start and stop. In the case of simultaneous water use, the relative stable water flow distribution state is maintained through the action of the shunt assembly 17. Without the shunt assembly 17, when the faucet 4 and the tankless pipeline machine 2 are working simultaneously, a sudden change in water consumption of one party (such as sudden closing of the faucet 4) can cause a large fluctuation in the internal water pressure of the purified water machine 3, resulting in frequent adjustment of the working state of the purified water machine 3. The shunt assembly 17 can maintain a relatively stable water pressure and water flow distribution, reducing the situation of frequent start and stop of the purified water machine 3 caused by changes in external water use.

[0083] The shunt assembly 17 can include a shunt diaphragm with a water passage hole and a fixing assembly for fixing the shunt diaphragm in the valve housing 11, wherein the shunt diaphragm can be of flexible material or provided with an expansion space, so that the shunt diaphragm can deform under the change of water pressure, thereby automatically opening or closing the backflow cavity 1146.
