Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drinking water equipment, and in particular to a cooked water pipeline machine. BACKGROUND

[0002] With the improvement of people's living standards, consumers pay more and more attention to the health of drinking water. Now the cooked water pipeline machine is more and more popular in the market, and the cooked water pipeline machine as an upgraded version of the pipeline machine can not only realize the demand of the ordinary pipeline machine, but also can meet the demand of quickly cooling the water heated to boiling state by the heat exchanger to the set temperature. Unlike the ordinary pipeline machine, the cooked water pipeline machine directly heats the purified water to the set temperature. Compared with other types of pipeline machines, the cooked water pipeline machine is more in line with the demand of Chinese people drinking cold boiled water.

[0003] The working principle of the existing cooked water pipeline machine is that the heating device is heated to high-temperature water boiling, and the low-temperature water without heating exchanges heat in the heat exchanger, so that the high-temperature room after boiling is cooled to the set temperature for water outlet. However, after the cooked water pipeline machine completes the water connection, the internal pipeline of the cooked water pipeline machine stores water. If the water outlet is not continuous, after a period of time, the water stored in the internal pipeline of the cooked water pipeline machine will gradually cool to room temperature. When the user needs relatively high-temperature cooked water later, the cold water stored in the pipeline behind the heating device will be discharged first, and the first cup of water obtained by the user is mostly cold water, which greatly reduces the user experience.

[0044] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict.

[0045] The familiar water pipeline machine provided by the embodiments of the present application mainly comprises a water tank module 1, a first heating device 2, a heat exchanger 3, a second heating device 4 and a water outlet assembly 5. The first heating device 2 is in communication with the water tank module 1, and is used for heating the water flowing into the water tank module 1; the heat exchanger 3 comprises first and second heat exchange flow channels capable of exchanging heat with each other, the outlet of the first heating device 2 can be in communication with the inlet of the first heat exchange flow channel; the inlet of the second heating device 4 is in communication with the outlet of the first heat exchange flow channel, and the outlet of the second heating device 4 is in communication with the inlet of the second heat exchange flow channel; the water outlet assembly 5 is in communication with the outlet of the second heat exchange flow channel.

[0046] The boiled water pipeline machine provided by the embodiment of the application realizes efficient and stable output of boiled water (cold boiled water) meeting the set temperature through the organic combination of the water tank module 1, the first heating device 2, the heat exchanger 3 (including the first heat exchange flow channel and the second heat exchange flow channel), the second heating device 4 and the water outlet assembly 5.

[0047] The water tank module 1 is one of the functions of storing water, providing an initial water source, and can ensure the water source stability of the boiled water pipeline machine system, and is suitable for various water inlet conditions. The first heating device 2 can preheat the inflowing cold water, flexibly control the water temperature, ensure that the water temperature entering the first heat exchange flow channel is suitable for the subsequent heat exchange requirement, and through the non-operation or low-power operation of the first heating device 2, it is helpful to quickly heat to the appropriate temperature to cooperate with the subsequent process. The structure of the heat exchanger 3 includes the first heat exchange flow channel and the second heat exchange flow channel, the first heat exchange flow channel is connected with the first heating device 2, the preliminarily heated water is transported to the second heating device 4 and used for heat exchange with the second heat exchange flow channel, the second heat exchange flow channel rapidly cools the boiled water through heat exchange with the second heat exchange flow channel, the double-flow channel design optimizes the heat exchange efficiency, while ensuring the cooling rate, and avoids energy waste. The second heating device 4 further heats the water passing through the first heat exchange flow channel to a boiling state, ensures the efficient boiling function, and makes the output boiled water meet the drinking requirements. The water outlet assembly 5 is used for outputting water to the user end, which can be communicated with the outlet of the second heat exchange flow channel of the heat exchanger 3, ensures that the user obtains the cooled boiled water, and improves the user experience.

[0048] The boiled water pipeline machine described above can be used to output boiled water, and the specific working logic of the boiled water output is as follows: in the stable working process, the water flow path of the boiled water output is: water tank module 1→first heating device 2→first heat exchange flow channel→second heating device 4→second heat exchange flow channel→water outlet assembly 5, wherein the first heating device 2 does not work or works at low power, so that the water temperature in the first heat exchange flow channel is relatively low, the second heating device 4 heats the water passing through it to boiling, and the high-temperature boiled water enters the second heat exchange flow channel and exchanges heat with the low-temperature water in the first heat exchange flow channel to complete the cooling, and then the boiled water (cold boiled water) is output from the water outlet assembly 5. In this working process, the first heating device 2 can flexibly control the water temperature entering the first heat exchange flow channel, which is beneficial to cooperating with the second heating device 4 to quickly boil the water in the second heating device 4, and on the other hand, can make the first heat exchange flow channel and the second heat exchange flow channel exchange heat to obtain the required boiled water temperature.

[0049] Through flexible regulation of the first heating device 2, the water temperature entering the first heat exchange channel is ensured to be appropriate, energy is saved, the boiling time of the second heating device 4 is shortened, and the water outlet speed is optimized. The design of the double-channel heat exchanger 3 effectively reduces the water outlet temperature, adapts to different boiled water requirements (such as different drinking temperatures), makes the boiled water temperature after heat exchange more accurate, and meets the drinking requirements of users for cold boiled water.

[0050] In the above boiled water pipeline machine, after completing water connection once, water is stored in the internal pipeline of the boiled water pipeline machine. If water outlet is not continuously performed, after a period of time, the water stored in the internal pipeline of the boiled water pipeline machine will gradually be cooled to room temperature. When the user needs relatively high-temperature boiled water next time, the cold water stored in the second heat exchange channel behind the second heating device 4 will be discharged first and exist in the first cup of water obtained by the user, resulting in low water temperature and greatly reducing the user experience. By changing the working logic, the above boiled water pipeline machine product structure can greatly improve this problem. Specifically, when the boiled water pipeline machine is used again after a long time without water outlet, in the initial stage, the first heating device 2 is controlled to work to obtain relatively high water temperature. The water flow enters the first heat exchange channel to heat the low-temperature water previously stored in the second heat exchange channel, so that the temperature of the low-temperature water in the second heat exchange channel is increased, the content of cold water in the first cup of water obtained by the user is greatly reduced, and the user experience is improved. After the water previously stored in the second heat exchange channel is discharged or is about to be discharged, the heating function of the first heating device 2 can be turned off or the heating power of the first heating device 2 can be reduced to obtain relatively low-temperature water, which enters the first heat exchange channel to cool and reduce the high-temperature water entering the second heat exchange channel from the second heating device 4, and the normal working logic is performed.

[0051] The embodiment of the present application reduces the content of cold water in the first cup of water through preheating in the initial stage, ensures that the temperature of the boiled water obtained by the user is more stable, and the working state of the first heating device 2 can be flexibly regulated to provide high-temperature water to heat the low-temperature water in the initial stage in the preheating stage and to provide low-temperature water for efficient cooling of boiled water in the normal stage.

[0052] In some embodiments, the flow channel area close to the inlet of the first heat exchange channel and the flow channel area close to the outlet of the second heat exchange channel can exchange heat. The water stored in the flow channel area close to the outlet of the second heat exchange channel will be preferentially discharged through the water discharge assembly compared with the water in other areas of the second heat exchange channel. The above setting can make the high-temperature water discharged from the first heating device 2 preferentially heat and warm the low-temperature water about to be discharged in the second heat exchange channel.

[0053] Specifically, the high-temperature water discharged from the first heating device 2 will enter the first heat exchange flow channel and first exchange heat with the low-temperature water about to be discharged in the second heat exchange flow channel. In this way, the high-temperature water discharged from the first heating device 2 is preferentially in contact with the low-temperature water near the outlet, thereby rapidly warming up and increasing the temperature of these low-temperature water. This process effectively increases the water temperature when the user first uses the water, reduces the discharge of cold water, ensures that the user obtains a more expected hot water temperature, and improves the user experience.

[0054] In some embodiments, the hot water pipeline machine comprises a first control valve 6, the inlet of the first control valve 6 is in communication with the outlet of the first heating device 2, the first outlet of the first control valve 6 is in communication with the water outlet assembly 5, and the second outlet of the first control valve 6 is in communication with the inlet of the first heat exchange flow channel. The purpose of this design is to achieve flexible control of the water flow path, thereby optimizing the overall working performance of the hot water pipeline machine, especially providing higher precision and efficiency in terms of water temperature adjustment and water flow sequence.

[0055] The first control valve 6 is connected to the outlet of the first heating device 2 through its inlet, and can control where the water flowing out of the first heating device 2 goes. When the user starts the hot water pipeline machine, the water first passes through the first heating device 2 and then enters the first control valve 6, which directs the water flow to the water outlet assembly 5 for direct water outlet according to the needs of the current working state, or to the first heat exchange flow channel through the second outlet for further heat exchange.

[0056] When the system needs direct water outlet, the first control valve 6 directs the water flow to the water outlet assembly 5 for user access. In this case, the water only passes through the first heating device 2 and does not pass through the heat exchanger and the second heating device 4. When the system needs to adjust the water temperature through heat exchange, the first control valve 6 directs the water flowing out of the first heating device 2 to the inlet of the first heat exchange flow channel to exchange heat with the water entering the second heat exchange flow channel. In this process, the water adjusts its temperature through heat exchange and finally enters the water outlet assembly 5 through the second heat exchange flow channel to provide users with hot water such as cold boiled water.

[0057] This flexible water flow control method can ensure efficient heat management and water temperature adjustment under different working requirements. By using the first control valve 6, the hot water pipeline machine can quickly switch between multiple working modes, optimize the water flow path and heat exchange process, and ensure the efficient operation and rapid response capability of the hot water pipeline machine.

[0058] In some embodiments, the hot water pipeline machine has a normal temperature water mode, a boiling water mode, and a hot water mode; when the hot water pipeline machine is in the normal temperature water mode or the boiling water mode, the inlet of the first control valve 6 is in communication with the first outlet of the first control valve 6; when the hot water pipeline machine is in the hot water mode, the inlet of the first control valve 6 is in communication with the second outlet of the first control valve 6.

[0059] Different working modes are achieved by switching of the first control valve 6 to adjust the water flow path, thereby meeting the user's demand for water of different temperatures. When the hot water pipeline machine is in the normal temperature water mode, the inlet of the first control valve 6 is in communication with the first outlet of the first control valve 6, at this time, the water flows out of the first heating device 2 and directly enters the water outlet assembly 5 through the first control valve 6, and the first heating device 2 does not heat in this mode, and the water temperature remains at the inlet water temperature. This mode is suitable for scenarios where the user needs normal temperature water. When the hot water pipeline machine is in the boiling water mode, the inlet of the first control valve 6 is still in communication with the first outlet of the first control valve 6. In this mode, the first heating device 2 works to heat the water flowing therethrough to a boiling state, which then directly enters the water outlet assembly 5 through the first control valve 6, thereby providing boiling water for the user. This mode is suitable for scenarios where the user directly needs boiling water. When the hot water pipeline machine is in the hot water mode, the inlet of the first control valve 6 is in communication with the second outlet of the first control valve 6, at this time, the water flows out of the first heating device 2 and is guided to the first heat exchange channel through the first control valve 6, and exchanges heat with the water in the second heat exchange channel. The high-temperature water in the second heat exchange channel completes rapid cooling and enters the water outlet assembly 5, providing hot water of suitable temperature. This mode is particularly suitable for scenarios where the user needs hot water.

[0060] Through flexible switching of the first control valve 6 and adjustment of the working state of the first heating device 2, the hot water pipeline machine can provide normal temperature water, boiling water, and hot water three types of drinking water solutions according to the user's demand, greatly improving the applicability and user experience of the product. At the same time, reasonable waterway design also ensures efficient switching of the water flow path, avoiding energy waste and unnecessary heat loss.

[0061] In some embodiments, the boiled water pipeline machine comprises a first waterway plate 7, and the first outlet of the first control valve 6 is in communication with the water outlet assembly 5 through the first waterway plate 7, and the second heat exchange flow channel is in communication with the water outlet assembly 5 through the first waterway plate 7. The design of the first waterway plate 7 realizes efficient management of different water flow paths, thereby improving the integration and working efficiency of the whole machine. In the normal temperature water mode and the boiling water mode, the first outlet of the first control valve 6 is in communication with the water outlet assembly 5 through the first waterway plate 7, and the water flowing through the first outlet of the first control valve 6 is introduced into the first waterway plate 7 and further guided to the water outlet assembly 5 by the first waterway plate 7, realizing the straight-through output of water. In the boiled water mode, the outlet of the second heat exchange flow channel is in communication with the water outlet assembly 5 through the first waterway plate 7, and after the water is processed by the first heating device 2, the first heat exchange flow channel and the second heat exchange flow channel, the boiled water is finally guided to the water outlet assembly 5 by the first waterway plate 7. The use of the first waterway plate 7 can effectively reduce the complexity of the direct connection pipeline, improve the compactness of the waterway arrangement, and ensure the clarity of the water flow path in different working modes.

[0062] The first waterway plate 7 centrally manages the water flow paths from the first control valve 6 and the second heat exchange flow channel, significantly optimizing the arrangement of the waterway, reducing the intersection and interference of the internal pipeline. Through modular design, the first waterway plate 7 is convenient for production and maintenance, while improving the reliability of the waterway system. The material of the first waterway plate 7 can be selected from high-temperature-resistant and corrosion-resistant engineering plastics or other suitable materials, further ensuring the stability of long-term use. Through the ingenious design and application of the first waterway plate 7, the boiled water pipeline machine can efficiently manage the water flow path in different modes, providing stable normal temperature water, boiling water and boiled water output for users, while also providing strong support for the integration and compactness of the product in design.

[0063] In some embodiments, the water tank module 1 comprises a water tank body 101 and a water tank cover assembly 102, the top of the water tank body 101 is formed with an opening, the water tank cover assembly 102 comprises a water tank cover 1021 and a drive pump 1022, the water tank cover 1021 is used to cover the top opening of the water tank body 101, and the drive pump 1022 is fixed on the water tank cover 1021 and used to drive the water in the water tank body 101 into the first heating device 2.

[0064] The water tank body 101 is the main part of the water tank module 1, which is usually made of durable materials such as food-grade plastic or stainless steel, and is used to store water sources. The top of the water tank body 101 is formed with an opening to facilitate the installation and removal of the water tank cover assembly 102, ensuring the supply and storage of water. The design of the opening also facilitates cleaning and maintenance in the water tank body 101.

[0065] The water tank cover 1021 is used to cover the top opening of the water tank body 101, seal the water tank body 101, prevent dust and debris from entering the water tank, and avoid water evaporation or pollution. The design of the water tank cover 1021 usually takes into account the sealing and convenience. The water tank body 101 and the water tank cover 1021 can be provided with a structure design that facilitates detachable connection, such as a buckle.

[0066] The drive pump 1022 is fixed on the water tank cover 1021 and directly connected to the water tank body 101. The function of the drive pump 1022 is to stably pump the water in the water tank body 101 into the first heating device 2, ensuring the stable operation of the hot water pipeline machine. The drive pump 1022 is a device that provides power for water flow in the hot water pipeline machine, which can extract water from the water tank body 101 and deliver it to the first heating device 2 in a short time, ensuring the stability and flow rate of water flow. As one of the core components of the water tank module 1, the drive pump 1022 ensures the smoothness of water flow, and the speed and efficiency of pumping water flow to the first heating device 2 directly affect the heating time of water and the outflow speed of hot water in the hot water pipeline machine. The power and adjustment function of the drive pump 1022 can usually be optimized according to the needs, which can not only ensure the rapid supply of water, but also avoid unnecessary energy waste.

[0067] The design of the water tank module 1 realizes efficient management of the water source, which not only ensures the smooth entry of water in the water tank into the heating system, but also adjusts the water flow through the drive pump 1022 to avoid affecting the heating effect due to too fast or too slow water flow. During the heating process, the drive pump 1022 continuously supplies water, ensuring that the first heating device 2 and the second heating device 4 can obtain sufficient water for heating, thereby quickly providing the required hot water for users.

[0068] In some embodiments, the water tank cover assembly 102 further comprises a water outlet pipe 1023, the water tank cover 1021 is internally formed with a water channel structure, the water outlet pipe 1023 is fixed on the water tank cover 1021, the water outlet pipe 1023 is in communication with the inlet of the water channel structure and extends into the interior of the water tank body 101, the outlet of the water channel structure is in communication with the inlet of the first heating device 2, and the drive pump 1022 is used to drive the water in the water tank body 101 to enter the first heating device 2 through the water outlet pipe 1023 and the water channel structure.

[0069] The water outlet pipe 1023 is fixed on the water tank cover 1021, which functions to transport the water in the water tank body 101 to the subsequent water path structure and ensure smooth water flow into the first heating device 2. The design of the water outlet pipe 1023 generally considers the stability of water flow, preventing poor water flow or leakage. The water outlet pipe 1023 generally extends into the interior of the water tank body 101 to contact the water source and deliver water flow through the water path structure. The water tank cover 1021 is internally provided with a water path structure for guiding the path of water flow, extracting water from the water tank body 101 and guiding it to the first heating device 2. The water path structure is generally composed of a series of pipes or channels integrated in the water tank cover 1021, ensuring smooth delivery of water flow. The driving pump 1022 is fixed on the water tank cover 1021, which functions to extract water from the water tank body 101 and deliver it through the water outlet pipe 1023, through the water path structure, and finally to the first heating device 2. The design of the driving pump 1022 ensures smooth water flow while providing sufficient water flow to ensure that the first heating device 2 can obtain sufficient water source.

[0070] The water path structure and water outlet pipe 1023 provided inside the water tank cover 1021 make the water flow path more concentrated and integrated, reducing the use of external pipelines and improving the overall stability and space utilization of the equipment. The driving pump 1022 cooperates with the water outlet pipe 1023 and the water path structure to ensure efficient and stable supply of water flow, avoiding problems such as poor water flow or stagnation in the water tank body 101, thereby improving heating efficiency.

[0071] In some embodiments, the water tank cover assembly 102 further comprises a second control valve 1024 fixed on the water tank cover 1021, which is configured to control the replenishment of an external water source into the interior of the water tank body 101.

[0072] The second control valve 1024 is fixed on the water tank cover 1021, which functions to control the replenishment of an external water source and ensure automatic regulation of the water level in the water tank body 101. Through the control of the second control valve 1024, the user can conveniently manage the water quantity in the water tank body 101, ensuring that there is sufficient water source in the water tank for subsequent water outlet processes. The configuration of the second control valve 1024 allows the external water source to be automatically or manually replenished into the water tank body 101 as needed. For example, the second control valve 1024 can automatically open and close the valve according to the change in water level in the water tank, adjust the flow of water source entering, and avoid the water tank body 101 from being unable to work normally or the water level being too low due to lack of water. In this way, the equipment can maintain stable water supply and avoid frequent manual water addition.

[0073] When the water level in the water tank body 101 is lower than the set level, the second control valve 1024 is automatically opened or manually opened by the user, allowing the external water source to enter the water tank body 101. After the water level in the water tank body 101 is restored to the set level, the second control valve 1024 is closed to stop the replenishment of the water source. This control process can be achieved through water level sensors or time control, thereby ensuring that the amount of water in the water tank is within the appropriate range. Through the design of the second control valve 1024, the water level in the water tank body 101 can be automatically adjusted, avoiding the situation of low water level in the water tank, reducing the need for user intervention, and improving the convenience of use. Integrating the second control valve 1024 on the water tank cover assembly 102 can also make rational use of the equipment space, simplify the pipeline structure, and make the entire water tank module 1 more compact.

[0074] During the operation of the device, the second control valve 1024 ensures that the water source in the water tank body 101 is sufficient. When the water level in the water tank is lower than the set value, the second control valve 1024 is opened to allow the external water source to flow into the water tank body 101 until the water level is restored. Through the effective management of the second control valve 1024, the water tank module 1 can maintain a constant water level, providing a stable water source for the heating device, thereby ensuring the normal operation of the hot water pipeline machine and good user experience.

[0075] To cooperate with the work of the second control valve 1024, the water tank cover assembly 102 also includes a liquid level sensor 1025 and a float switch 1026 integrated on the water tank cover 1021. The liquid level sensor 1025 is used to monitor the water level in the water tank body 101 in real time, and the float switch 1026 can control the replenishment of the water source according to the change of the water level. When the water level in the water tank body 101 is lower than the preset minimum water level, the float switch 1026 triggers the second control valve 1024 to allow the external water source to replenish into the water tank body 101, ensuring that the water level in the water tank body 101 is at an appropriate level, thereby ensuring the normal operation of the hot water pipeline machine and preventing dry burning.

[0076] There is heat exchange between the first heat exchange flow channel and the second heat exchange flow channel in the heat exchanger 3, such as: the high-temperature water in the second heat exchange flow channel exchanges heat with the low-temperature water in the first heat exchange flow channel, so that the water temperature in the second heat exchange flow channel decreases and the water temperature in the first heat exchange flow channel increases. At the same time, the heat exchange mode of the two can be various, such as: the outer walls of the first heat exchange flow channel and the second heat exchange flow channel contact each other to realize contact heat exchange; or the water in the first heat exchange flow channel flows on the outer wall of the second heat exchange flow channel; or the water in the second heat exchange flow channel flows on the outer wall of the first heat exchange flow channel, etc. Preferably, the second heat exchange flow channel is located inside the second heat exchange flow channel, which can increase the heat exchange efficiency between the first heat exchange flow channel and the second heat exchange flow channel during the heat exchange process, so that the hot water in the second heat exchange flow channel is cooled to the required temperature, and the hot water output effect is improved.

[0077] In some embodiments, the water tank module 1 further comprises an ultraviolet sterilization device 103 arranged on the water tank body 101. The ultraviolet sterilization device 103 can effectively kill bacteria, viruses and other microorganisms in the water by irradiating the water in the water tank body 101 with ultraviolet light, ensuring the safety of the water for the user to drink. The installation position of the ultraviolet sterilization device 103 is usually at the upper or side part of the water tank body 101 to ensure that the water can be fully exposed to ultraviolet light to achieve the best sterilization effect.

[0078] In the related art, the internal structure of the conventional pipeline machine is usually arranged loosely with low integration, which leads to a large amount of space waste, which is not conducive to the installation and maintenance of the product and increases the assembly time. In order to solve this problem, the embodiments of the present application improve the integration of the product by modular design and optimization of the waterway structure, so that the hot water pipeline machine has a more compact structure, which is convenient for installation and maintenance, and improves the overall integration.

In order to realize the transition connection between the second heating device 4 and the second heat exchange flow channel, the eighth water outlet end 402 of the second heating device 4 is communicated with the sixth water inlet end 303 of the second heat exchange flow channel through the third waterway plate 9. Specifically, the third waterway plate 9 has an eighth water inlet end 901 and a ninth water outlet end 902 communicated through a waterway.

[0088] The application also provides a control method of the cooked water pipeline machine, which is applied to the cooked water pipeline machine provided in the foregoing embodiments of the application. The control method of the cooked water pipeline machine includes the following steps 100-200.

[0089] Step 100: Determine the working mode of the cooked water pipeline machine currently in, and the specific working mode includes but is not limited to the normal temperature water mode, the boiling water mode and the cooked water mode. Specifically, the working mode of the cooked water pipeline machine currently in can be determined according to the use demand of the user or the preset instruction. The normal temperature water mode is to directly provide the room temperature water stored in the water tank module 1 without heating; the boiling water mode is to provide the water heated to the boiling state by high temperature; and the cooked water mode is to provide the cooked water with a suitable temperature, and the precise water temperature control is realized by heating and heat exchange.

[0090] Step 200: If the cooked water pipeline machine is in the cooked water mode, the first heating device 2 is controlled to communicate with the outlet of the first heat exchange flow channel, and the second heating device 4 is controlled to heat the water passing therethrough to the boiling state. In this step, the first control valve 6 is adjusted to ensure that the outlet of the first heating device 2 communicates with the inlet of the first heat exchange flow channel, the water is preliminarily controlled in temperature by the first heat exchange flow channel, a basic condition is provided for subsequent temperature adjustment, the second heating device 4 is controlled to operate at high power, the water passing therethrough is heated to the boiling state, and the high-temperature water exchanges heat with the water in the first heat exchange flow channel through the second heat exchange flow channel, so that the outlet water temperature reaches the suitable cooked water standard.

[0091] In this step, the temperature change of the water flow in different regions of the heat exchanger 3 can be monitored in real time to ensure that the water temperature at the outlet of the second heat exchange flow channel reaches the preset cooked water standard. According to the detection result, the power output of the first heating device 2 can be dynamically adjusted to further optimize the energy efficiency and the water quality and meet the diversified drinking water demand of the user. The energy in the heat exchange process can also be reasonably utilized to reduce the energy consumption of the heating process and improve the efficiency of the whole machine.

[0092] As a specific optional control mode, when the cooked water pipeline machine is in the cooked water mode, step 200 in the control method specifically includes steps 210-230.

[0093] Step 210: Obtain the initial temperature T of the water in the second heat exchange channel. The initial temperature T of the stored water in the second heat exchange channel is detected by a temperature sensor, and the temperature value is compared with a preset threshold in the subsequent steps as the basis for subsequent control.

[0094] Step 220: If the initial temperature T is lower than the first preset temperature T1, in the first stage, control the first heating device 2 to heat the water passing through it to the second preset temperature T2, and in the second stage, control the first heating device 2 to heat the water passing through it to the third preset temperature T3, T3≤T1≤T2.

[0095] If the initial temperature T is lower than the first preset temperature T1, it means that the temperature of the water stored in the second heat exchange channel is relatively low, which may cause the temperature of the first cup of water to be low. Therefore, heating operation needs to be carried out in stages. In the first stage, the first heating device 2 is controlled to work, and the water passing through it is heated to the second preset temperature T2, where T2>T1. By flowing the heated water into the first heat exchange channel, heat exchange is directly performed on the low-temperature water stored in the second heat exchange channel, thereby increasing the temperature of the water stored in the second heat exchange channel. In the second stage, when the temperature of the water in the second heat exchange channel gradually rises and the cold water is emptied, the working state of the first heating device 2 is adjusted, and the water passing through it is heated to the third preset temperature T3, where T3≤T1. The operation in this stage ensures that the temperature of the water entering the heat exchanger 3 adapts to the subsequent heat exchange requirements, thereby creating conditions for the process of outputting hot water. The running time of the first stage is a preset time, and then enters the second stage. The preset time is set based on the time required to empty the original cold water in the second heat exchange channel. The volume of the second heat exchange channel and the water output speed of the water output assembly are determined by the product parameters of the hot water pipeline machine. The time required to empty the original cold water in the second heat exchange channel can be determined. The preset time can be the time used to empty the cold water or slightly fluctuate up and down. Those skilled in the art can make specific selection and setting according to needs.

[0096] Step 230: If the initial temperature T is not lower than the first preset temperature T1, control the first heating device 2 to heat the water passing through it to the third preset temperature T3. If the initial temperature T is not lower than the first preset temperature T1, it means that the temperature of the water stored in the second heat exchange channel is already close enough to the temperature required for hot water. At this time, the first heating device 2 can be directly controlled to heat the water passing through it to the third preset temperature T3, avoiding unnecessary staged heating operation and improving water output efficiency.

[0097] The control logic can solve the problem of low temperature of the first cup of water. By adjusting the heat in stages, the temperature of the water stored in the second heat exchange channel is preferentially increased, avoiding the direct flow of cold water affecting user experience. Moreover, under the premise of ensuring the temperature of the first cup of water, excessive heating can be avoided, energy consumption can be reduced, and the waiting time for water output can be shortened.

[0098] In some embodiments, the cooked water pipeline machine comprises a first control valve 6, an inlet of the first control valve 6 being in communication with an outlet of the first heating device 2, a first outlet of the first control valve 6 being in communication with the water outlet assembly 5, and a second outlet of the first control valve 6 being in communication with an inlet of the first heat exchange flow channel; the control method further comprises: if the cooked water pipeline machine is in the normal temperature water mode or the boiling water mode, controlling the inlet of the first control valve 6 to be in communication with the first outlet of the first control valve 6; and if the cooked water pipeline machine is in the cooked water mode, controlling the inlet of the first control valve 6 to be in communication with the second outlet of the first control valve 6.

[0099] In the normal temperature water mode or the boiling water mode, the user demand is normal temperature water or boiling water without heat exchange. The first control valve 6 is controlled to switch to the state of the inlet being in communication with the first outlet. After the water flows through the first heating device 2, the water directly flows to the water outlet assembly 5 through the first outlet of the first control valve 6, to complete water supply and meet the user demand for normal temperature water or boiling water, thereby simplifying the water path and improving the water outlet speed.

[0100] In the cooked water mode, the user demand is cooked water with heat exchange temperature adjustment. The first control valve 6 is controlled to switch to the state of the inlet being in communication with the second outlet. After the water flows through the first heating device 2, the water enters the first heat exchange flow channel through the second outlet of the first control valve 6, exchanges heat with the high-temperature water in the second heat exchange flow channel, is adjusted to the cooked water temperature required by the user, and finally enters the water outlet assembly 5 through the outlet of the heat exchanger 3 to complete water supply.

[0101] The control method precisely controls the water flow path through the two communication states of the first control valve 6, to adapt to the diversified demand of the normal temperature water mode, the boiling water mode and the cooked water mode. In the normal temperature water mode or the boiling water mode, the water path is simplified to reduce the waiting time. In the cooked water mode, the water temperature is intelligently adjusted through heat exchange to avoid excessively high or low water outlet temperature. Through dynamic adjustment of the water flow path, energy waste can be reduced, heat loss can be reduced, unnecessary heat exchange process in the boiling water mode or the cooked water mode can be avoided, and the overall efficiency can be improved.

[0102] In some embodiments, the control method further comprises: if the hot water pipeline machine is in the normal temperature water mode, controlling the first heating device 2 not to heat the water flow passing through the inside thereof. In the normal temperature water mode, the user demand is unheated water, and the normal temperature water in the water tank module 1 is directly provided, while the energy consumption is reduced. The water flows from the water tank body 101 into the first heating device 2 through the driving pump 1022, directly flows out without being heated, enters the water outlet assembly 5 through the first outlet of the first control valve 6, and completes the water supply. The heating function of the first heating device 2 is stopped to avoid unnecessary energy consumption, and the water directly flows to the water outlet assembly 5, which shortens the water supply time. In the normal temperature water mode, the first heating device 2 stops working, which also helps to prolong the service life of the equipment.

[0103] In some embodiments, the control method further comprises: if the hot water pipeline machine is in the normal temperature water mode, controlling the first heating device 2 not to heat the water flow passing through the inside thereof. In the normal temperature water mode, the user demand is unheated water, and the normal temperature water in the water tank module 1 is directly provided, while the energy consumption is reduced. The water flows from the water tank body 101 into the first heating device 2 through the driving pump 1022, directly flows out without being heated, enters the water outlet assembly 5 through the first outlet of the first control valve 6, and completes the water supply. The heating function of the first heating device 2 is stopped to avoid unnecessary energy consumption, and the water directly flows to the water outlet assembly 5, which shortens the water supply time. In the normal temperature water mode, the first heating device 2 stops working, which also helps to prolong the service life of the equipment.

[0104] In some embodiments, the control method further comprises: if the hot water pipeline machine is in the normal temperature water mode, controlling the first heating device 2 not to heat the water flow passing through the inside thereof. In the normal temperature water mode, the user demand is unheated water, and the normal temperature water in the water tank module 1 is directly provided, while the energy consumption is reduced.
