[0046] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the accompanying drawings.

[0047] The following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] ​​In the description of the present application, it is understood that the terms "first", "second" and the like are only for the purpose of description and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. The association relationship of the associated objects is described, which means that there can be three relationships, for example, A and / or B can represent the three cases of A alone, A and B together, and B alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the specification of the present application is only for the purpose of describing specific embodiments and is not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0050] The embodiments of the present application provide a pure drinking system, which is a comprehensive system integrating water purification and convenient drinking water functions. The pure drinking system can be applied to places such as homes, offices, schools, hospitals, etc., which are not specifically limited by the embodiments of the present application.

[0051] Please refer to Figure 1 , the pure drinking system includes 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 of impurities in tap water. The precision filtering uses higher filtering technology to remove small molecular substances, 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 refrigeration of the purified pure water, so as to facilitate users to accurately obtain drinking water and meet different drinking water temperature requirements of users.

[0052] Please continue to refer to Figure 1In some embodiments, the direct drinking system can further comprise a faucet 4, which can be directly connected with the water purifier 3, so that the faucet 4 can directly flow out the purified pure water from the water purifier 3. Further, considering that the water pressure in the water supply pipeline for providing tap water to the water purifier 3 can change due to various factors (such as water supply peak, pipeline maintenance, etc.), a pressure reducing valve is usually configured before the raw water inlet 31 of the water purifier 3, which not only stabilizes the water pressure in the water supply pipeline and reduces the water pressure entering the water purifier 3 in advance, but also avoids physical damage to the water purifier 3 due to excessive water pressure. In order to simultaneously distribute the purified pure water to the tankless pipeline machine 2 and the faucet 4 and improve water utilization efficiency, a flow divider is usually configured at the rear end of the pure water outlet 32 of the water purifier 3. The water inlet end of the tankless pipeline machine 2 and the water inlet of the faucet 4 are both in communication with the flow divider. When the user needs to take temperature-adjusted direct drinking water, such as 5℃-15℃ ice water in hot summer, 40℃-50℃ warm water for washing milk powder, or 90℃-99℃ hot water for making tea, the user can open the tankless pipeline machine 2 for use. When the user needs to take domestic water for washing tableware or washing fruits and vegetables or washing clothes, the user can open the faucet 4 for use.

[0053] Please continue to refer to Figure 1 However, the independent pressure reducing valve and flow divider are respectively installed in the water purification system, which occupies more space and causes pipeline layout to be messy, increasing installation difficulty. Moreover, when a fault occurs, the pressure reducing valve and the flow divider need to be detected and repaired separately, and replacement of the pressure reducing valve and / or the flow divider in the limited space will greatly increase the complexity of operation and maintenance cost. Therefore, in view of the existing problems, the water purification system can further comprise a flow divider 1, wherein the faucet 4, the tankless pipeline machine 2, the water purifier 3 and the tap water supply pipeline are all in communication with the flow divider 1, so that the water supply pipeline can introduce tap water to the flow divider 1 and adjust and maintain the excessively high and unstable water pressure of the tap water in the water supply pipeline within a preset pressure value range, finally generating stabilized water and delivering it to the water purifier 3. The water purifier 3 will generate pure water after deep filtration and purification treatment of the stabilized water, and the purified pure water from the water purifier 3 can flow into the flow divider 1, and then be introduced to the tankless pipeline machine 2 and the faucet 4 through the flow divider 1. The pure water flowing to the faucet 4 will be used as domestic water, and the pure water flowing to the tankless pipeline machine 2 will be used as direct drinking water.

[0054] The tankless pipeline machine 2 will be described in detail below.

[0055] The water tankless pipeline machine 2 has the advantages that, as the water tankless design, on the one hand, the water tankless pipeline machine 2 does not occupy too much space, so that the water tankless pipeline machine 2 is small in size; on the other hand, as the water tankless pipeline machine 2 does not need to store water, the water tankless pipeline machine 2 does not need to maintain the water temperature of the water tank, so that the energy consumption is reduced, and the problem that bacteria are easily bred in the traditional pipeline machine with a water tank is avoided, and thus the water quality of the water tankless pipeline machine 2 is improved.

[0056] In combination Figures 1 to 3 The water tankless pipeline machine 2 can include a shell 21, a waterway system 22, an electric control device 24, and a quick heating device 25.

[0057] 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, and shock resistance, and can maintain stable performance in various harsh environments, so that the normal work of the water tankless pipeline machine 2 can be ensured.

[0058] The shell 21 is formed with a mounting cavity 215, and the mounting cavity 215 can be divided into an electric control mounting area 213, a waterway mounting area 2141, and a quick heating mounting area 2142 arranged in sequence; the electric control device 24 is installed in the electric control mounting area 213, the waterway system 22 is installed in the waterway mounting area 2141, and the quick heating device 25 is installed in the quick heating mounting area 2142 and connected to the electric control device 24 through wires. The waterway system 22 is used to supply water to the quick heating device 25. The electric control device 24 is used to control the working conditions of the waterway system 22 and the quick heating device 25. Through preset programs and algorithms, the electric control device 24 can accurately adjust the water flow speed, water temperature, and other parameters to meet the different needs of users.

[0059] It can be understood that the quick 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, so that, optionally, the electric control device 24 and the quick heating device 25 are arranged in the length direction of the water tankless pipeline machine 2, so that the electromagnetic interference can be reduced to ensure the stability and reliability of the electric signal of the electric control device 24. In the length direction of the water tankless pipeline machine 2, the electric control device 24, the waterway system 22, and the quick 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 quick heating device 25, so that the thermal energy interaction interference is reduced.

[0060] The shell 21 has a water inlet 211 and a water outlet 212, wherein the shell 21 can include a first shell and a second shell, and the first shell and the second shell can be detachably connected by clamping, screw connection, or the like. The first shell and the second shell enclose the above-mentioned mounting cavity 215.

[0061] It should be noted that the water inlet 211 and the water outlet 212 can be in the form of a pipeline formed integrally on the shell 21, and can also be in the form of a separate component, such as a hose or a connector, etc. The first shell and / or the second shell are formed with 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.

[0062] Optionally, as Figure 4 The water system 22 includes, in sequence in the flow direction of the water flow, a first water inlet electromagnetic valve 2211, a negative pressure valve 2217, a water volume sensor 2215, a flow meter 2216, and a pump assembly 2212. The first water inlet electromagnetic valve 2211 is connected to the water inlet 211. Since there is no water tank design, the water system 22 needs to be provided with the first water inlet electromagnetic valve 2211 and the pump assembly 2212 to cooperate. 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 the power of the water flow.

[0063] The pump assembly 2212 can include a flow control pump and a water pump. When the pump assembly 2212 includes a water pump, the water system 22 further includes a negative pressure valve 2217 connected to the first water inlet electromagnetic valve 2211 and the water pump to prevent negative pressure (i.e. pressure lower than atmospheric pressure) in the pipeline, thereby protecting the water pump and other components in the water system 22 from damage.

[0064] The flow meter 2216 is used to measure the flow of the water flow to provide accurate water usage data for the user, helping the user to understand the water usage rules of the tankless pipeline machine 2. The water volume sensor 2215 can monitor the water volume in the water system 22 in real time, and stop or reduce the power of the instant heating device 25 in time when the water volume is insufficient, to prevent dry burning 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.

[0065] In combination with the above, the electric control device 24 is arranged in the shell 21 to control the related components of the water system 22 and the instant heating device 25 as a whole. In the related art, a plurality of fasteners such as screws are usually required to lock the electric control device on the shell, which is complicated to operate and has a high cost.

[0066] To solve the above problems, in combination Figures 4 to 6In the embodiment of the present application, the housing 21 is internally structured with a limiting groove 218 and is provided with a first connecting portion 219 spaced from the limiting groove 218. The electric control device 24 specifically comprises an electric control box 241 and a main control board 242 arranged in the electric control box 241. The electric control box 241 serves as a mounting base of the main control board 242 and is used for accommodating and protecting the main control board 242. The main control board 242 is electrically connected with the waterway system 22 and the instant heating device 25. The limiting groove 218 is arranged in the electric control mounting area 213. One end of the electric control box 241 is inserted into the limiting groove 218 and is limited by the inner wall of the limiting groove 218. The other end of the electric control box 241 is provided with a second connecting portion 2413. The second connecting portion 2413 is detachably connected with the first connecting portion 219.

[0067] The inner wall of the limiting groove 218 can limit the movement of the electric control box 241 through clamping or pressing, for example, the limiting groove 218 can limit the movement of the electric control box 241 along the thickness direction of the housing 21, or the limiting groove 218 can limit the movement of the electric control box 241 along the width direction of the housing 21. During assembly, the electric control box 241 can be first inserted into the limiting groove 218 for pre-positioning, and then the first connecting portion 219 and the second connecting portion 2413 are connected. The first connecting portion 219 and the second connecting portion 2413 can be connected by snap connection or screw connection, which is not limited herein.

[0068] Optionally, in the mode that the first connecting portion 219 and the second connecting portion 2413 are connected by screws, the screw hole of the first connecting portion 219 can pass through the plate of the housing 21, so that the screw can be screwed from the outside of the housing 21 to the inside of the housing 21, which is convenient to operate.

[0069] Therefore, in the embodiment of the present application, the housing 21 limits one end of the electric control device 24 through the limiting groove 218, and the other end of the electric control device 24 is connected with the first connecting portion 219 and the second connecting portion 2413. Thus, the electric control device 24 can be pre-positioned by the limiting groove 218 during assembly, which makes the assembly operation more smooth. In addition, the installation and fixation of the electric control device 24 can be completed only by connecting the first connecting portion 219 and the second connecting portion 2413, which makes the disassembly and assembly of the electric control device 24 more convenient, and the operation is simple and the disassembly and assembly efficiency is higher. In addition, since the electric control device 24 and the housing 21 are fixed by the first connecting portion 219 and the second connecting portion 2413, the number of fasteners is reduced, and the cost is reduced.

[0070] As Figure 5 and Figure 6As shown, in some embodiments, the mounting cavity 215 includes an intersecting side wall and a surrounding wall connected to the peripheral side of the side wall. Optionally, the side wall is perpendicular to the thickness direction of the shell 21. For example, the shell 21 includes a first shell 21 and a second shell 21 spaced apart along the thickness direction of the shell 21, and the first shell 21 and the second shell 21 enclose the mounting cavity 215, and the electric control box 241 can be mounted on one of the first shell 21 and the second shell 21. For example, the electric control box 241 is mounted on the second shell 21, and the side wall is the wall surface of the second shell 21 facing the first shell 21. The surrounding wall is arranged around the side wall and extends along the thickness direction of the shell 21. The surrounding wall is provided with a limiting portion 2181, and the limiting portion 2181 and the side wall jointly define a limiting groove 218, so as to limit the electric control box 241 on the side wall, increase the contact area of the electric control box 241 and the side wall, improve the stability of the electric control box 241, and make the connection of the electric control box 241 and the shell 21 more compact, and improve the space utilization.

[0071] In some embodiments, the surrounding wall includes a first wall surface 2151, a second wall surface 2152 and a third wall surface 2153 connected to each other, and the first wall surface 2151, the second wall surface 2152 and the third wall surface 2153 are connected to different sides of the side wall, respectively. For example, the first wall surface 2151 is located at the top of the side wall, the second wall surface 2152 is located at the back of the side wall, and the third wall surface 2153 is located at the bottom of the side wall. The electric control mounting area 213 is arranged at the rear half of the shell 21, and the limiting groove 218 of the present embodiment is arranged close to the first wall surface 2151, the second wall surface 2152 and the third wall surface 2153. The intersection of the first wall surface 2151 and the second wall surface 2152 and the intersection of the second wall surface 2152 and the third wall surface 2153 are both corners, and the limiting portion 2181 is arranged at least one of the intersection of the first wall surface 2151 and the second wall surface 2152 and the intersection of the second wall surface 2152 and the third wall surface 2153. When the limiting portion 2181 is only one, it can be arranged at the intersection of the first wall surface 2151 and the second wall surface 2152 or the intersection of the second wall surface 2152 and the third wall surface 2153, and when the limiting portion 2181 is multiple, it can be arranged at the intersection of the first wall surface 2151 and the second wall surface 2152 and the intersection of the second wall surface 2152 and the third wall surface 2153.

[0072] It is worth noting that the limiting portion 2181 arranged at the intersection of the first wall surface 2151 and the second wall surface 2152 can be understood as being arranged at the position where the first wall surface 2151 and the second wall surface 2152 are connected, or being arranged at the end of the first wall surface 2151 close to the second wall surface 2152, or being arranged at the end of the second wall surface 2152 close to the first wall surface 2151. Similarly, the limiting portion 2181 arranged at the intersection of the second wall surface 2152 and the third wall surface 2153 can be understood in the same way.

[0073] By matching the limiting portion 2181 with the intersection of the first wall surface 2151 and the second wall surface 2152 and the intersection of the second wall surface 2152 and the third wall surface 2153, the end of the electric control box 241 can be limited in a targeted manner, and the electric control box 241 can be limited by the surrounding wall, thereby improving the stability of the electric control box 241.

[0074] For example, the number of limiting portions 2181 is at least two, wherein the at least two limiting portions 2181 are respectively arranged on the first wall surface 2151 and the third wall surface 2153 and oppositely arranged. In this way, the two opposite sides of the end of the electric control box 241 can be limited symmetrically, the contact area of the limiting portion 2181 and the electric control box 241 is increased, and the stability of the electric control box 241 is further improved.

[0075] In some embodiments, the limiting portion 2181 and the side wall are arranged in the thickness direction of the shell 21, and define a limiting groove 218. One end of the electric control device 24 is inserted between the limiting portion 2181 and the side wall, and abuts against at least one of the limiting portion 2181 and the side wall. For example, the limiting portion 2181 and the side wall abut against two opposite side surfaces of the electric control box 241 in the thickness direction of the shell 21, so as to clamp the electric control box 241.

[0076] Optionally, the limiting portion 2181 includes a limiting column, and the bottom surface of the limiting column is arranged in the thickness direction of the shell 21. The bottom surface of the limiting column abuts against one side surface of the electric control box 241. Of course, in other embodiments, the limiting portion 2181 can also be a limiting plate, and the limiting plate and the side wall are arranged in the thickness direction of the shell 21 to form the limiting groove 218. The present application does not limit this.

[0077] Further, the number of limiting portions 2181 is at least two, and the at least two limiting portions 2181 are arranged in the circumferential direction of the side wall. The limiting groove 218 is located between the at least two limiting portions 2181, the contact area of the limiting portion 2181 and the electric control box 241 is increased, and the stability of the electric control box 241 is improved.

[0078] In some embodiments, the one end of the electric control device 24 located in the limiting groove 218 abuts against the side surface of the at least two limiting portions 2181 and is clamped by the two limiting portions 2181. Specifically, the two limiting portions 2181 are respectively located at the intersection of the first wall surface 2151 and the second wall surface 2152 and the intersection of the second wall surface 2152 and the third wall surface 2153. The end of the electric control box 241 is located between the two limiting portions 2181, and the two limiting portions 2181 abut against the upper and lower sides of the end of the electric control box 241, thereby forming clamping limiting.

[0079] Optionally, the limiting part 2181 comprises a limiting column, a bottom surface of the limiting column is spaced apart from the side wall, and a side surface of the limiting column abuts against the electric control box 241. It can be understood that the bottom surface of the limiting column being spaced apart from the side wall can reduce the length of the limiting column and save materials.

[0080] As shown in Figure 4 , the electric control device 24 is provided with at least two chamfered parts at one end in the limiting groove 218, and the at least two chamfered parts are matched with the at least two limiting parts 2181 respectively. By arranging the chamfered parts, on one hand, the electric control device 24 can be prevented from being stuck when being put into the shell 21, and on the other hand, when the side surface of the limiting part 2181 abuts against the chamfered part, the contact area between the two can be increased, and the stability of the electric control box 241 can be improved.

[0081] In some embodiments, the second connecting part 2413 is located at one end of the electric control device 24 away from the limiting groove 218. The space is sufficient for connection, and by fixing the one end of the electric control device 24 away from the limiting groove 218, the installation of the electric control device 24 can be further fastened in cooperation with the limiting groove 218, and the stability of the electric control device 24 can be improved.

[0082] Optionally, the shell 21 further comprises a plurality of limiting ribs 2154, the plurality of limiting ribs 2154 are arranged around the electric control device 24, and the side surface of the electric control device 24 abuts against the side edges of the plurality of limiting ribs 2154. The limiting ribs 2154 can be connected to the surrounding wall. In this way, the electric control device 24 is limited by the limiting ribs 2154, and the stability of the electric control device 24 in the shell 21 is further improved, and the electric control device 24 is prevented from being displaced.

[0083] The tankless pipeline machine 2 further comprises a power line 216, which can supply power to the devices of the waterway system 22 and the electric control device 24. In the related art, the circuit wiring of some pipeline machines is relatively messy, which is inconvenient for maintenance and has safety hazards.

[0084] In combination Figure 7 , the outer wall of the electric control box 241 is provided with a wiring groove 246, and the electric control box 241 is further provided with a wire inlet 244 communicating the wiring groove 246 with the internal space of the electric control box 241. Part of the power line 216 is arranged in the wiring groove 246, and one end of the power line 216 penetrates through the wire inlet 244 and is electrically connected with the main control board 242.

[0085] Therefore, the embodiment of the present application can avoid the risk of strong current and weak current parallel use between the power line 216 and the control line of the main control board 242, improve safety, and can also store the power line 216 in the wire slot 246, improve the orderliness of the wire in the shell 21, make the wire in the shell 21 more tidy, and facilitate maintenance.

[0086] In an embodiment, part of the power line 216 is arranged in the waterway installation area 2141 to separate the power line 216 from the instant heating device 25; that is, in the length direction of the water tank pipeline machine 2, the electric control device 24 and the instant heating device 25 are arranged apart, and since the instant heating device 25 and the electric control device 24 will generate heat during operation, the power line 216 close to the instant heating device 25 or the electric control device 24 will affect the power line 216. Therefore, the embodiment of the present application arranges the power line 216 in the waterway installation area 2141, and the waterway installation area 2141 is located between the instant heating installation area 2142 and the electric control installation area 213, so as to reduce the heat energy interaction interference.

[0087] In the embodiment, the wire inlet 244 is located on the side of the electric control box 241 away from the waterway installation area 2141, the power line 216 penetrates from the waterway installation area 2141 to the electric control installation area 213, and enters the internal space of the electric control box 241 from the wire inlet 244, so as to avoid the interference between the power line 216 and the connecting wire of the waterway system 22, and reduce the complexity of the wire.

[0088] It can be understood that the electric control box 241 is also provided with a wire outlet 245 communicating with the internal space thereof, and the wire connected with the main control board 242 penetrates out of the wire outlet 245 and is connected with the waterway system 22 and the instant heating device 25. The wire outlet 245 is located on the side of the electric control box 241 close to the waterway installation area 2141, so that the wire outlet 245 is close to the waterway system 22, facilitating the connection of the wire, which is conducive to reducing the length of the wire, reducing the cost, avoiding the excessive length of the wire, and reducing the complexity of the wire. In addition, the wire outlet 245 and the wire inlet 244 are located on different sides of the electric control box 241, which can further separate the wire from the power line 216, avoid interference, and improve safety.

[0089] As Figure 7As shown, in some embodiments, the electric control box 241 comprises a box body 2411 and an upper cover 2412. The box body 2411 is mounted in the shell 21, the main control board 242 is arranged in the box body 2411, and the upper cover 2412 is connected with the box body 2411. The upper cover 2412 and the box body 2411 can be connected by buckling, screws or the like, which is not limited here. The wiring groove 246 is arranged on the side of the upper cover 2412 away from the box body 2411. Among them, the upper cover 2412 is provided with a wire inlet 244 or the upper cover 2412 and the box body 2411 jointly define the wire inlet 244, and the box body 2411 is provided with a wire outlet 245 or the upper cover 2412 and the box body 2411 jointly define the wire outlet 245.

[0090] In an embodiment, the wiring groove 246 is arranged along the length direction of the shell 21, and one end of the wiring groove 246 communicates with the wire inlet 244, so that the power cord 216 arranged therein is regular, and the neatness of the wire in the shell 21 is improved.

[0091] In an embodiment, the slot of the wiring groove 246 faces one side wall of the shell 21, such as the left side wall or the right side wall, and the electric control box 241 further comprises a wire blocking plate 247 arranged at the slot of the wiring groove 246 and spaced apart from the bottom wall of the wiring groove 246 to limit the movement of the power cord 216 from the slot out of the wiring groove 246, avoid the power cord 216 from falling off, and improve the stability of the power cord 216.

[0092] Further, the number of wire blocking plates 247 is multiple, and the multiple wire blocking plates 247 are arranged in the length direction of the shell 21 to be spaced apart, so as to be limited at multiple places in the extension direction of the power cord 216, and further improve the stability of the power cord 216. Alternatively, the number of wire blocking plates 247 is multiple, and the multiple wire blocking plates 247 are respectively connected on opposite sides of the wiring groove 246 and are arranged in a staggered manner, so that the power cord 216 is uniformly stressed and is not easy to fall out.

[0093] In the related art, the heating effect of the heating device of the pipe machine is single, which cannot completely meet the use demand of the user.

[0094] In combination Figures 7 to 9 In an embodiment of the present application, the main control board 242 comprises a power adjusting module 2421. The power adjusting module 2421 is connected with the instant heating device 25 through at least two groups of wires, so as to make the instant heating device 25 run at different powers based on the conduction of different groups of wires and the instant heating device 25.

[0095] For example, for one group of wires, the power adjustment module 2421 applies a voltage of 36V to the instant heating device 25 through the group of wires, and for another group of wires, the power adjustment module 2421 applies a voltage of 48V to the instant heating device 25 through the group of wires. After applying different voltages, the instant heating device 25 operates at different powers for the same instant heating device 25.

[0096] It can be understood that for the working condition of the tankless pipeline machine 2 requiring fast water output, the power adjustment module 2421 makes the instant heating device 25 operate at high power, and for the working condition without the requirement of fast water output, the power adjustment module 2421 makes the instant heating device 25 operate at low power. In this way, in the tankless pipeline machine 2 of the embodiment of the present application, the power adjustment module 2421 of the electric control device 24 connects the instant heating device 25 through two groups of different wires, so that the instant heating device 25 can operate at different powers, and can meet the diversified water output requirements of users. In addition, the instant heating device 25 selects the appropriate operating power according to different working conditions, and through targeted power adjustment, the operation of the instant heating device 25 is more reasonable, the waste of resources of the instant heating device 25 is reduced or avoided, energy saving and cost reduction are realized, and the user experience is improved.

[0097] In a specific embodiment, the tankless pipeline machine 2 includes at least two live wires 251 and one neutral wire 252, and the at least two live wires 251 and the one neutral wire 252 are connected to the power adjustment module 2421 and the instant heating device 25. Each live wire 251 and the neutral wire 252 are configured as a group of wires. That is, the plurality of live wires 251 share one neutral wire 252, which ensures that only one group of wires is connected at the same time, and ensures the normal operation of the instant heating device 25. Sharing the neutral wire 252 can also reduce the number of wires, not only reducing the cost, but also reducing the complexity of the pipeline in the shell 21, facilitating wiring assembly and operation and maintenance.

[0098] Optionally, in an embodiment, the electric control device 24 further comprises a master control module 2422, which is arranged on the master control board 242 and is electrically connected with the power adjusting module 2421. In this embodiment, the water tank-free pipeline machine 2 has at least two operation modes, and the master control module 2422 is configured to control the power adjusting module 2421 to connect the instant heating device 25 through different wires based on different operation modes. For example, the water tank-free pipeline machine 2 has a fast water outlet mode and a normal water outlet mode. In the fast water outlet mode, the master control module 2422 controls the power adjusting module 2421 to make the instant heating device 25 operate at high power. In the normal water outlet mode, the master control module 2422 controls the power adjusting module 2421 to make the instant heating device 25 operate at a general power lower than the high power. The switching of the operation modes can be actively switched by the user or intelligently switched by the master control module 2422 according to preset conditions. The control of the power adjusting module 2421 by the master control module 2422 is used to switch the operating power of the instant heating device 25, thereby improving the intelligent level of the water tank-free pipeline machine 2 and improving the use experience.

[0099] Alternatively, in an embodiment, the electric control device 24 further comprises a switch module, which is used to switch the on-off state of the at least two groups of wires and the power adjusting module 2421 and the instant heating device 25. The switching of the on-off state of the at least two groups of wires by the switch module can realize the power switching of the instant heating device 25, which is simple and reliable in structure. Further, the shell 21 further comprises an operation button arranged movably, the operation button is connected with the switch module, and the switch module is configured to switch the on-off state of the at least two groups of wires and the power adjusting module 2421 and the instant heating device 25 based on the movement of the operation button. That is, the user can directly control the power switching of the instant heating device 25 by operating the operation button, thereby improving the use experience of the user.

[0100] In an embodiment, the water tank-free pipeline machine 2 further comprises a display device arranged on the shell 21 to display the working information of the water tank-free pipeline machine 2. It can be understood that the display device can be electrically connected with the electric control device 24, the display device can receive signals and data from the electric control device 24, and display the working information of the water tank-free pipeline machine 2, such as the water outlet temperature, the water outlet temperature, the WiFi connection and the like. Further, the working information comprises the heating power of the instant heating device 25, so that the user can intuitively master the current operating condition of the instant heating device 25. Alternatively, the working information comprises mode information corresponding to the heating power of the instant heating device 25, such as the fast water outlet mode, the normal water outlet mode and the like, which is not limited in the embodiments of the present application.

[0101] The master control board 242 generates heat during operation. In the related art, the electric control module of some pipeline machines is cooled through a cooling hole, and water droplets or dust can fall into the electric control module through the cooling hole, which affects the normal work of the electric control module and exists a safety hazard.

[0102] In combination Figure 7 , Figure 10 and Figure 11 , in the embodiment, the electric control box 241 is provided with a containing cavity 243, the main control board 242 is arranged in the containing cavity 243, the electric control box 241 is further provided with a heat dissipation channel 248, two ends of the heat dissipation channel 248 are provided with a first flow port 2481 and a second flow port 2482, the first flow port 2481 is communicated with the outside, and the second flow port 2482 is communicated with the containing cavity 243. In this way, the containing cavity 243 is communicated with the outside, and the heat can be dissipated by the heat dissipation channel 248.

[0103] The projection of the first flow port 2481 and the projection of the second flow port 2482 partially coincide or do not coincide along the wall thickness direction of the wall surface where the heat dissipation channel 248 is located. For example, the heat dissipation channel 248 is arranged on the side wall of the electric control box 241 perpendicular to the thickness direction of the shell 21, and the wall thickness direction of the wall surface where the heat dissipation channel 248 is located is the thickness direction of the shell 21. The projection of the first flow port 2481 and the projection of the second flow port 2482 partially coincide along the thickness direction of the shell 21, and at this time, the heat dissipation channel 248 is observed along the thickness direction of the shell 21, and the heat dissipation channel 248 is partially blocked, and the main control board 242 can only be observed through part of the heat dissipation channel 248. Or the projection of the first flow port 2481 and the projection of the second flow port 2482 do not coincide along the thickness direction of the shell 21, and at this time, the heat dissipation channel 248 is observed along the thickness direction of the shell 21, and the heat dissipation channel 248 is completely blocked, and the main control board 242 cannot be observed through the heat dissipation channel 248. Therefore, the channel wall of the heat dissipation channel 248 can block at least part of the water droplets or dust and other foreign matters falling towards the main control board 242.

[0104] In the embodiment, the electric control box 241 dissipates heat through the heat dissipation channel 248 communicated with the containing cavity 243 and the outside, and the projection of the first flow port 2481 and the projection of the second flow port 2482 partially coincide or do not coincide along the wall thickness direction of the wall surface where the heat dissipation channel 248 is located, so that the channel wall of the heat dissipation channel 248 can block at least part of the water droplets or dust and other foreign matters falling towards the heat dissipation channel 248, thereby ensuring the heat dissipation effect of the electric control device 24, reducing or avoiding the water droplets or foreign matters from the outside falling into the containing cavity 243 to affect the main control board 242, and improving the safety of the electric control device 24.

[0105] In an embodiment, the heat dissipation channel 248 is arranged to extend obliquely relative to the wall thickness direction of the wall surface where the heat dissipation channel 248 is located, so that the oblique channel wall can block the clothes and guide the airflow to ensure the heat dissipation effect.

[0106] Optionally, in one embodiment, the first flow channel 2481 and the second flow channel 2482 have the same shape. For example, both the first flow channel 2481 and the second flow channel 2482 are strip-shaped or elliptical. The identical shape of the first flow channel 2481 and the second flow channel 2482 can make the heat dissipation channel 248 more regular, the airflow smooth, and ensure the heat dissipation and shielding effects.

[0107] Furthermore, the width of the first flow channel opening 2481 is D, satisfying the relationship 2.5mm≤D≤3.5mm. It can be understood that if the width D is greater than 3.5mm, the wider opening width makes it easier for foreign objects to enter the receiving cavity 243; while if the width is less than 2.5mm, the narrow opening width will reduce the heat dissipation effect. Therefore, in order to ensure the heat dissipation effect and minimize the interference of foreign objects, this embodiment limits the width D of the first flow channel opening 2481 to satisfy 2.5mm≤D≤3.5mm, and D can be selected as 3mm, 3.1mm, etc.

[0108] The length of the first flow channel 2481 is L, which can optionally satisfy the relationship 30mm≤L≤50mm. It can be understood that if the length L is greater than 50mm, it is easier for foreign objects to enter the receiving cavity 243; while if the length L is less than 30mm, it is easy to reduce the heat dissipation effect. Therefore, in order to ensure the heat dissipation effect and minimize the interference of foreign objects, this embodiment limits the length L of the first flow channel 2481 to satisfy 30mm≤L≤50mm, and L can be selected as 35mm, 40mm, etc.

[0109] The distance H between the first flow channel 2481 and the second flow channel 2482 can optionally satisfy the relationship 2.5mm≤H≤3mm. Understandably, the distance between the first flow channel 2481 and the second flow channel 2482 is the wall thickness. If the distance H is greater than 3mm, the heat dissipation channel 248 is deeper and has a thicker wall, which is not conducive to heat dissipation and increases material costs. Conversely, if the distance H is less than 2.5mm, the heat dissipation channel 248 is shallower, making it easier for foreign objects to enter the receiving cavity 243, and the wall thickness is thinner, resulting in lower strength of the housing 2411. Therefore, to ensure the strength of the housing 2411 and control costs, and to minimize interference from foreign objects while ensuring heat dissipation, this embodiment limits the distance H between the first flow channel 2481 and the second flow channel 2482 to satisfy 2.5mm≤H≤3mm, where H can be 2.8mm, 3mm, etc.

[0110] like Figure 11 and Figure 12 As shown, in some embodiments, the electrical control box 241 is provided with multiple heat dissipation channels 248, which are arranged at intervals along the length of the housing 21 to improve the heat dissipation effect.

[0111] In a specific embodiment, the electric control box 241 comprises a box body and a plurality of grid bars 249. A containing cavity 243 is formed in the box body, and a heat dissipation opening is arranged in communication with the containing cavity 243. Optionally, the heat dissipation opening is arranged on the side wall of the electric control box 241 perpendicular to the length direction of the shell 21. The plurality of grid bars 249 are connected to the box body and are arranged at the heat dissipation opening in the length direction of the shell 21 at intervals, and a heat dissipation channel 248 is defined between any two adjacent grid bars 249.

[0112] The box body comprises a box body 2411 and an upper cover 2412. The upper cover 2412 is connected to the box body 2411 and cooperates with the box body 2411 to form the containing cavity 243. The heat dissipation opening is arranged on the upper cover 2412. The upper cover 2412 is connected to the plurality of grid bars 249. The upper cover 2412 and the plurality of grid bars 249 can be an integral component, which is convenient for production and has good structural integrity. Of course, the upper cover 2412 and the plurality of grid bars 249 can also be separately formed and then connected. This application does not limit this.

[0113] In some embodiments, the grid bar 249 comprises an upper channel wall and a lower channel wall arranged oppositely. Both the upper channel wall and the lower channel wall are arranged obliquely. In the length direction of the shell 21, the upper channel wall of a front grid bar 249 cooperates with the lower channel wall of a rear adjacent grid bar 249 to form a heat dissipation channel 248. In this way, a plurality of heat dissipation channels 248 are defined by the cooperation between the grid bars 249. The arrangement of the plurality of heat dissipation channels 248 is regular, which ensures the heat dissipation effect.

[0114] Further, the upper channel wall and the lower channel wall have the same degree of inclination, and the central axes of the plurality of heat dissipation channels 248 are arranged in parallel. That is, the plurality of heat dissipation channels 248 have the same degree of inclination and are arranged in parallel, so as to avoid airflow turbulence, ensure the heat dissipation effect, and facilitate production to make the structure more regular and beautiful.
