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 and a control method thereof. Background Art

[0002] As people's living standards improve, consumers pay more and more attention to the health of drinking water. Now the cooked water pipeline machine on the market is becoming more and more popular among consumers. As an upgraded version of the pipeline machine, the cooked water pipeline machine can not only meet the needs of ordinary pipeline machines, but also meet the needs of heating purified water to boiling state and then cooling it to the set temperature through the heat exchanger to achieve rapid cooling. Instead of directly heating the purified water to the set temperature like ordinary pipeline machines, compared with other types of pipeline machines, the cooked water pipeline machine is more in line with the needs of Chinese people to drink boiled water.

[0003] The working principle of the existing boiled water pipeline machine is to heat the high-temperature water heated to boiling by the heating device with the low-temperature water that has not been heated in the heat exchanger, so that the high-temperature chamber after boiling is cooled to the set temperature for water discharge. However, after the boiled water pipeline machine completes the water collection, water is stored in the internal pipeline of the boiled water pipeline machine. If the water is not discharged continuously, after a period of time, the water stored in the internal pipeline of the boiled water pipeline machine will gradually cool down to room temperature. When the user needs boiled water with a relatively high temperature later, the cold water stored in the pipeline behind the heating device will be discharged first. The first cup of water obtained by the user is often all or most of it is cold water, which greatly reduces the user experience. Summary of the invention

[0052] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0053] The cooked water pipeline machine provided in the embodiment of the present application mainly includes 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 connected to the water tank module 1 and is used to heat the water flowing into the water tank module 1; the heat exchanger 3 includes a first heat exchange channel and a second heat exchange channel that can exchange heat with each other, and the outlet of the first heating device 2 can be connected to the inlet of the first heat exchange channel; the inlet of the second heating device 4 is connected to the outlet of the first heat exchange channel, and the outlet of the second heating device 4 is connected to the inlet of the second heat exchange channel; the water outlet assembly 5 is connected to the outlet of the second heat exchange channel.

[0054] The cooked water pipeline machine provided in the embodiment of the present application realizes efficient and stable output of cooked water (boiled water) that meets 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 channel and the second heat exchange channel), the second heating device 4 and the water outlet component 5.

[0055] One of the functions of the water tank module 1 is to store water supply and provide an initial water source, which can ensure the stability of the water source of the cooked water pipeline machine system and adapt to a variety of water inlet conditions. The first heating device 2 can preheat the incoming cold water and flexibly adjust the water temperature to ensure that the water temperature entering the first heat exchange channel is suitable for the subsequent heat exchange requirements. When the first heating device 2 is not running or running at low power, it helps to quickly heat to a suitable temperature to match the subsequent process. The structure of the heat exchanger 3 includes a first heat exchange channel and a second heat exchange channel. The first heat exchange channel is connected to the first heating device 2, and the preliminarily heated water is transported to the second heating device 4 and used for heat exchange with the second heat exchange channel. The second heat exchange channel quickly cools the boiling water through heat exchange with the second heat exchange channel. The dual channel design optimizes the heat exchange efficiency, while ensuring the cooling rate, avoiding energy waste. The second heating device 4 further heats the water passing through the first heat exchange channel to a boiling state, ensuring an efficient boiling function, so that the output cooked water meets the drinking requirements. The water outlet component 5 is used to output water to the user end, and it can be connected to the second heat exchange flow channel outlet of the heat exchanger 3 to ensure that the user obtains cooked water after cooling, thereby improving the user experience.

[0056] The above-mentioned cooked water pipeline machine can be used to produce cooked water. The specific working logic of producing cooked water is: in a stable working process, the water flow path of the cooked water is: water tank module 1 → first heating device 2 → first heat exchange channel → second heating device 4 → second heat exchange channel → water outlet assembly 5, wherein the first heating device 2 does not work or works at low power, so that the water temperature entering the first heat exchange channel is relatively low, and the second heating device 4 heats the water passing through it to boiling. After the boiling high-temperature water enters the second heat exchange channel, it exchanges heat with the low-temperature water in the first heat exchange channel to complete the cooling and then produces cooked water from the water outlet assembly 5, i.e. boiled water. In this working process, the first heating device 2 can flexibly control the water temperature entering the first heat exchange channel. On the one hand, it is conducive to cooperating with the second heating device 4 to quickly boil the water in the second heating device 4, and on the other hand, it can make the first heat exchange channel and the second heat exchange channel exchange heat to obtain the required cooked water temperature.

[0057] Through the flexible regulation of the first heating device 2, the water temperature entering the first heat exchange flow channel is ensured to be appropriate, which not only saves energy, but also shortens the boiling time of the second heating device 4, which helps to optimize the water outlet speed. The double-flow design of the heat exchanger 3 effectively reduces the outlet water temperature, adapts to different cooked water requirements (such as different drinking temperatures), and makes the cooked water temperature after heat exchange more accurate, meeting the user's drinking needs for boiled water.

[0058] In the above cooked water pipeline machine, after completing one water connection, water is stored in the internal pipeline of the cooked water pipeline machine. If the water is not discharged continuously, after a period of time, the water stored in the internal pipeline of the cooked water pipeline machine will gradually cool down to room temperature. When the user needs cooked water with a relatively high temperature later, 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, which greatly reduces the user experience. The product structure of the above cooked water pipeline machine can greatly improve this problem by changing the working logic. Specifically, when the cooked water pipeline machine is used again after not discharging water for a long time, in the initial stage, the first heating device 2 is controlled to work to obtain a relatively high water temperature. After the water flows into the first heat exchange channel, the low-temperature water previously retained in the second heat exchange channel is heated, so that the temperature of the low-temperature water in the second heat exchange channel is increased, which can greatly reduce the content of cold water in the first cup of water obtained by the user and improve the user experience. After the water previously retained in the second heat exchange channel is drained or is about to be drained, 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 water with a relatively low temperature, which enters the first heat exchange channel to cool down the boiling high-temperature water that enters the second heat exchange channel from the second heating device 4, and perform normal working logic.

[0059] The embodiment of the present application reduces the cold water content in the first cup of water through preheating in the initial stage, ensuring that the temperature of the cooked water obtained by the user is more stable. The working state of the first heating device 2 can be flexibly adjusted, which can provide high-temperature water in the preheating stage to heat the low-temperature water in the initial stage, and provide low-temperature water in the normal stage to efficiently cool the boiling water.

[0060] In some embodiments, the flow channel area of ​​the first heat exchange flow channel near its inlet and the flow channel area of ​​the second heat exchange flow channel near its outlet can exchange heat. The water stored in the flow channel area of ​​the second heat exchange flow channel near its outlet will be discharged through the drainage component first compared to the water in other areas of the second heat exchange flow channel. The above arrangement can make the high-temperature water discharged from the first heating device 2 preferentially heat the low-temperature water to be discharged from the second heat exchange flow channel.

[0061] Specifically, the high-temperature water discharged from the first heating device 2 will enter the first heat exchange channel and first exchange heat with the low-temperature water to be discharged from the second heat exchange channel. In this way, the high-temperature water discharged from the first heating device 2 will first contact the low-temperature water near the outlet, so that the low-temperature water will quickly heat up and increase its temperature. This process effectively increases the water temperature of the user when the water is discharged for the first time, reduces the discharge of cold water, ensures that the cooked water temperature obtained by the user is more in line with expectations, and improves the user experience.

[0062] In some embodiments, the cooked water pipeline machine includes a first control valve 6, the inlet of the first control valve 6 is connected to the outlet of the first heating device 2, the first outlet of the first control valve 6 is connected to the water outlet assembly 5, and the second outlet of the first control valve 6 is connected to 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 cooked water pipeline machine, especially providing higher accuracy and efficiency in terms of water temperature regulation and water flow sequence.

[0063] 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 flows. When the user starts the boiled water pipeline machine, the water first passes through the first heating device 2 and then enters the first control valve 6. The first control valve 6 guides the water flow through its first outlet to the water outlet component 5 for direct water discharge, or guides the water flow through the second outlet to the first heat exchange channel for continued heat exchange according to the requirements of the current working state.

[0064] When the system needs to directly discharge water, the first control valve 6 guides the water flow to the water outlet component 5 for the user to use. 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 guides the water flowing out of the first heating device 2 to the entrance of the first heat exchange channel to exchange heat with the water entering the second heat exchange channel. In this process, the water adjusts its temperature through heat exchange, and finally enters the water outlet component 5 through the second heat exchange channel for users to obtain boiled water.

[0065] This flexible water flow control method can ensure that the system can achieve efficient heat management and water temperature regulation under different working requirements. By using the first control valve 6, the cooked 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 cooked water pipeline machine.

[0066] In some embodiments, the cooked water pipeline machine has a normal temperature water mode, a boiling water mode and a cooked water mode; when the cooked water pipeline machine is in the normal temperature water mode or the boiling water mode, the inlet of the first control valve 6 is connected to the first outlet of the first control valve 6; when the cooked water pipeline machine is in the cooked water mode, the inlet of the first control valve 6 is connected to the second outlet of the first control valve 6.

[0067] Different working modes adjust the water flow path by switching the first control valve 6, so as to meet the user's needs for water of different temperatures. When the cooked water pipeline machine is in the normal temperature water mode, the inlet of the first control valve 6 is connected to the first outlet of the first control valve 6. At this time, after the water flows out of the first heating device 2, it directly enters the water outlet component 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 water inlet temperature. This mode is suitable for scenarios where users need normal temperature water. When the cooked water pipeline machine is in the boiling water mode, the inlet of the first control valve 6 is still connected to the first outlet of the first control valve 6. In this mode, the first heating device 2 works, and after heating the water flowing through to a boiling state, it directly enters the water outlet component 5 through the first control valve 6, thereby providing boiling water to the user. This mode is suitable for scenarios where users directly need boiling water. When the cooked water pipeline machine is in the cooked water mode, the inlet of the first control valve 6 is connected to the second outlet of the first control valve 6. At this time, after the water flows out from the first heating device 2, it is guided to the first heat exchange channel through the first control valve 6 to exchange heat with the water in the second heat exchange channel. The high-temperature water in the second heat exchange channel enters the water outlet component 5 after rapid cooling, providing cooked water with suitable temperature. This mode is particularly suitable for scenarios where users need cooked water.

[0068] Through the flexible switching of the first control valve 6 and the adjustment of the working state of the first heating device 2, the cooked water pipeline machine can provide three types of drinking water solutions: room temperature water, boiled water and cooked water according to the needs of users, which greatly improves the applicability of the product and user experience. At the same time, the reasonable water channel design also ensures the efficient switching of the water flow path, avoiding energy waste and unnecessary heat loss.

[0069] In some embodiments, the cooked water pipeline machine includes a first water circuit plate 7, the first outlet of the first control valve 6 is connected to the water outlet assembly 5 through the first water circuit plate 7, and the second heat exchange channel is connected to the water outlet assembly 5 through the first water circuit plate 7. The design of the first water circuit 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 connected to the water outlet assembly 5 through the first water circuit plate 7, and the first outlet of the first control valve 6 guides the water flowing through into the first water circuit plate 7, which is further guided to the water outlet assembly 5 by the first water circuit plate 7 to realize the direct output of water. In the cooked water mode, the outlet of the second heat exchange channel is connected to the water outlet assembly 5 through the first water circuit plate 7, and the water is finally guided to the water outlet assembly 5 by the first water circuit plate 7 to output cooked water after being processed by the first heating device 2, the first heat exchange channel and the second heat exchange channel. The use of the first waterway plate 7 can effectively reduce the complexity of directly connecting pipelines, improve the compactness of the waterway layout, and ensure that the water flow path is clear in different working modes.

[0070] The first water circuit plate 7 centrally manages the water flow path from the first control valve 6 and the second heat exchange flow channel, significantly optimizes the layout of the water circuit, and reduces the intersection and interference of internal pipes. Through modular design, the first water circuit plate 7 is easy to produce and maintain, while improving the reliability of the water system. The material of the first water circuit plate 7 can be selected from high temperature resistant, corrosion resistant engineering plastics or other suitable materials to further ensure stability in long-term use. Through the ingenious design and application of the first water circuit plate 7, the water flow path of the cooked water pipeline machine in different modes can be efficiently managed, providing users with stable output of normal temperature water, boiling water and cooked water, while also providing strong support for the integration and compactness of the product in design.

[0071] In some embodiments, the water tank module 1 includes a water tank body 101 and a water tank cover assembly 102, the water tank body 101 has an opening at the top, the water tank cover assembly 102 includes a water tank cover 1021 and a driving pump 1022, the water tank cover 1021 is used to cover the top opening of the water tank body 101, the driving pump 1022 is fixed on the water tank cover 1021, and the driving pump 1022 is used to drive the water in the water tank body 101 into the first heating device 2.

[0072] 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. An opening is formed on the top of the water tank body 101 to facilitate the installation and removal of the water tank cover assembly 102 to ensure the supply and storage of water. The design of the opening is also convenient for cleaning and maintenance in the water tank body 101.

[0073] 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 evaporation or pollution of the water source. The design of the water tank cover 1021 usually takes into account sealing and convenience. The water tank body 101 and the water tank cover 1021 can be provided with a structural design that facilitates the detachable connection between the two, such as a buckle.

[0074] The driving pump 1022 is fixed on the water tank cover 1021 and directly connected to the water tank body 101. The function of the driving pump 1022 is to stably pump the water in the water tank body 101 into the first heating device 2 to ensure the stable operation of the cooked water pipeline machine. The driving pump 1022 is a device that provides power for the flow of water in the cooked water pipeline machine. It can extract water from the water tank body 101 and transport it to the first heating device 2 in a short time to ensure the stability and flow rate of the water flow. As one of the core components of the water tank module 1, the driving pump 1022 ensures the smoothness of the water flow. In the cooked water pipeline machine, the speed and efficiency of pumping water to the first heating device 2 directly affect the heating time of the water and the output speed of the cooked water. The power and adjustment function of the driving pump 1022 can usually be optimized according to demand, which can not only ensure the rapid supply of water, but also avoid unnecessary energy waste.

[0075] The design of the water tank module 1 realizes efficient management of the water source, which not only ensures that the water in the water tank enters the heating system smoothly, but also can adjust the water flow by driving the pump 1022 to avoid affecting the heating effect due to too fast or too slow water flow. During the heating process, the driving 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 user with the required cooked water.

[0076] In some embodiments, the water tank cover assembly 102 also includes a water outlet pipe 1023, a water channel structure is formed inside the water tank cover 1021, the water outlet pipe 1023 is fixed on the water tank cover 1021, the water outlet pipe 1023 is connected to the inlet of the water channel structure and extends into the water tank body 101, the outlet of the water channel structure is connected to the inlet of the first heating device 2, and the driving 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.

[0077] The water outlet pipe 1023 is fixed on the water tank cover 1021, and its function is to transport the water in the water tank body 101 to the subsequent water channel structure and ensure that the water flows smoothly into the first heating device 2. The design of the water outlet pipe 1023 usually takes into account the stability of the water flow to prevent the water flow from being stagnant or leaking. The water outlet pipe 1023 usually extends into the interior of the water tank body 101 so as to contact the water source and transfer the water flow through the water channel structure. A water channel structure is provided inside the water tank cover 1021, which is used to guide the path of the water flow, extract water from the water tank body 101 and guide it to the first heating device 2. The water channel structure is usually composed of a series of pipes or channels integrated in the water tank cover 1021 to ensure the smooth delivery of the water flow. The driving pump 1022 is fixed on the water tank cover 1021. The function of the driving pump 1022 is to extract water from the water tank body 101 and transport it to the first heating device 2 through the water outlet pipe 1023 and the water channel structure. The design of the driving pump 1022 ensures the smooth flow of water and provides sufficient water flow to ensure that the first heating device 2 can obtain sufficient water source.

[0078] The water path structure and the water outlet pipe 1023 disposed inside the water tank cover 1021 make the water flow path more centralized and integrated, reduce the use of external pipes, and improve 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, avoid the problem of poor water flow or water retention in the water tank body 101, thereby improving the heating efficiency.

[0079] In some embodiments, the water tank cover assembly 102 further includes a second control valve 1024 , which is fixed to the water tank cover 1021 , and the second control valve 1024 is configured to control the external water source to replenish the water tank body 101 .

[0080] The second control valve 1024 is fixed on the water tank cover 1021, and its function is to control the replenishment of the external water source to ensure the automatic adjustment of the water level inside the water tank body 101. Through the control of the second control valve 1024, the user can easily manage the water volume of the water tank body 101 to ensure that there is enough water in the water tank for the subsequent water discharge process. 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 of the water level in the water tank, adjust the flow rate of the water source entering, and avoid the water tank body 101 from failing to work properly or the water level is too low due to lack of water. In this way, the equipment can maintain a stable water supply and avoid frequent manual water addition.

[0081] When the water level in the water tank body 101 is lower than the set level, the second control valve 1024 opens automatically or is opened manually by the user, allowing an external water source to enter the water tank body 101. After the water level in the water tank body 101 returns to the set level, the second control valve 1024 closes and stops replenishing the water source. This control process can be achieved through a water level sensor or time control to ensure that the amount of water in the water tank is within a suitable range. Through the design of the second control valve 1024, the water level of the water tank body 101 can be automatically adjusted, avoiding the situation where the water level in the water tank is too low, 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 equipment space, simplify the pipeline structure, and make the entire water tank module 1 more compact.

[0082] When the device is working, the second control valve 1024 ensures that there is sufficient water in the water tank 101. When the water level in the water tank is lower than the set value, the second control valve 1024 opens to allow external water to flow into the water tank 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 and provide a stable water source for the heating device, thereby ensuring the normal operation of the cooked water pipeline machine and a good user experience.

[0083] In order 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 water source according to the change of water level. When the water level in the water tank body 101 is lower than the preset minimum water level, the float switch 1026 will trigger the second control valve 1024, allowing 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 cooked water pipeline machine and preventing the occurrence of dry burning.

[0084] There is heat exchange between the first heat exchange channel and the second heat exchange channel in the heat exchanger 3, for example: the high-temperature water in the second heat exchange channel exchanges heat with the low-temperature water in the first heat exchange channel, so that the water temperature in the second heat exchange channel decreases and the water temperature in the first heat exchange channel increases. At the same time, there can be multiple ways of heat exchange between the two, for example: the outer walls between the first heat exchange channel and the second heat exchange channel are in contact with each other to achieve contact heat exchange; or, the water in the first heat exchange channel flows on the outer wall of the second heat exchange channel; or, the water in the second heat exchange channel flows on the outer wall of the first heat exchange channel, etc. Preferably, the second heat exchange channel is located inside the second heat exchange channel. During the heat exchange process, the heat exchange efficiency between the first heat exchange channel and the second heat exchange channel can be increased, so that the hot water in the second heat exchange channel is cooled to the required temperature, thereby improving the cooked water effect.

[0085] In some embodiments, the water tank module 1 further includes an ultraviolet sterilization device 103 disposed 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 rays, thereby ensuring the safety of the user's drinking water. The ultraviolet sterilization device 103 is usually installed on the upper part or side of the water tank body 101 to ensure that the water can be fully exposed to ultraviolet rays to achieve the best disinfection effect.

[0086] In the related art, the internal structure of the traditional pipeline machine is usually loosely arranged and has low integration, which leads to a lot of space waste, which is not only not conducive to the installation and maintenance of the product, but also increases the assembly time. In order to address this problem, the embodiment of the present application improves the integration of the product through modular design and optimization of the waterway structure, so that the cooked water pipeline machine has a more compact structure, which is easy to install and maintain, and improves the overall integration.

[0087] As shown in the figure, the internal structure of the cooked water pipeline machine of the present application is located at the bottom of the water tank module 1, and the water tank cover 1021 is installed on the top of the water tank body 101. The water tank body 101 and the water tank cover 1021 can not only effectively store water, but also serve as a supporting basis for other key structures. According to the previous description, the water outlet pipe 1023, the drive pump 1022, the second control valve 1024, the liquid level sensor 1025 and the float switch 1026 in the water tank cover assembly 102 are all fixed on the water tank cover 1021, and the water channel structure is provided inside the water tank cover 1021. This design greatly improves the integration of the water tank cover assembly 102, thereby effectively reducing the waste of space and improving the functional integration of the entire system.

[0088] In some embodiments, the structure arranged in the middle area in the vertical direction includes a first heating device 2, a heat exchanger 3, a drive pump 1022, a second control valve 1024, and a second heating device 4.

In order to realize the transition connection between the first heating device 2 and the first control valve 6, the inlet of the first control valve 6 is connected to the first heating device 2 through the second water channel plate 8. Specifically, the first control valve 6 is a one-inlet and two-outlet solenoid valve, a second water inlet end 601 is formed at the inlet of the first control valve 6, a second water outlet end 602 is formed at the first outlet, a third water outlet end 603 is formed at the second outlet, and the first water outlet end 202 and the second water inlet end 601 are connected through the second waterway plate 8.

[0089] A third water inlet end 701, a fourth water inlet end 702, a fourth water outlet end 703 and a fifth water outlet end 704 are formed on the first water circuit plate 7, wherein the third water inlet end 701 is connected to the fourth water outlet end 703, the fourth water inlet end 702 is connected to the fifth water outlet end 704, the fourth water outlet end 703 and the fifth water outlet end 704 are both connected to the water outlet component 5, and the third water inlet end 701 on the first water circuit plate 7 is connected to the second water outlet end 602 of the first control valve 6.

[0090] The two ends of the first heat exchange channel of the heat exchanger 3 respectively form a fifth water inlet end 301 and a sixth water outlet end 302, and the two ends of the second heat exchange channel respectively form a sixth water inlet end 303 and a seventh water outlet end 304; the fifth water inlet end 301 of the first heat exchange channel is connected to the third water outlet end 603 of the first control valve 6, and the seventh water outlet end 304 of the second heat exchange channel is connected to the fourth water inlet end 702 of the first water circuit plate 7.

[0091] The lower end of the second heating device 4 on the left side of the middle area is the seventh water inlet end 401, which is used to connect with the sixth water outlet end 302 of the first heat exchange flow channel, and the upper end of the second heating device 4 is the eighth water outlet end 402. In order to achieve 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 connected 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 connected by a waterway, the eighth water outlet end 402 of the second heating device 4 is connected with the eighth water inlet end 901 of the third waterway plate 9, and the ninth water outlet end 902 of the third waterway plate 9 is connected with the sixth water inlet end 303 of the second heat exchange flow channel.

[0092] The structure arranged in the upper area in the vertical direction includes the first control valve 6, the first waterway plate 7, the second waterway plate 8 and the third waterway plate 9. The rightmost side of the upper area is the first control valve 6 and the second waterway plate 8 connected to each other, the leftmost side of the upper area is the third waterway plate 9, and the middle part of the upper area is the first waterway plate 7.

Flexible waterway switching and functional expansion are achieved through the first waterway plate 7, the second waterway plate 8 and the third waterway plate 9, which facilitates the modular layout design of each structure. The clear structural partition and reasonable port layout facilitate installation, disassembly and maintenance. This regional layout and modular design significantly improves the performance and user experience of the cooked water pipeline machine, while meeting the requirements of modern household appliances for efficient use of space and easy maintenance. It can not only effectively utilize the internal space of the product, but also increase the product function without increasing the product volume.

[0095] During product production, the water tank module 1, the first heating device 2, the second heating device 4, the first waterway plate 7, the second waterway plate 8, the third waterway plate 9, the first control valve 6, the heat exchanger 3 and other structures are assembled as a whole and then installed as a whole into the rear shell 12, which is convenient for the production of the whole machine and increases production efficiency. Reasonable use of the internal space can reduce the size of the appearance parts, reduce material costs, and greatly improve the product processing efficiency and user experience.

[0096] The embodiment of the present application also provides a control method for a cooked water pipeline machine, which is applied to the cooked water pipeline machine provided in the above embodiment of the present application. The control method for the cooked water pipeline machine includes the following steps 100 to 200.

[0097] Step 100: Determine the current working mode of the cooked water pipeline machine, and the specific working modes include but are not limited to normal temperature water mode, boiling water mode and cooked water mode. Specifically, the current working mode of the cooked water pipeline machine can be determined according to the user's usage requirements or preset instructions. The normal temperature water mode directly provides room temperature water stored in the water tank module 1 without heating; the boiling water mode provides water that has been heated to a boiling state at a high temperature; the cooked water mode provides cooked water at a suitable temperature, and achieves precise water temperature control through heating and heat exchange.

[0098] Step 200: If the cooked water pipeline machine is in the cooked water mode, the first heating device 2 is controlled to be connected to the outlet of the first heat exchange channel, and the second heating device 4 is controlled to heat the water passing through it to a boiling state. In this step, the first control valve 6 is adjusted to ensure that the outlet of the first heating device 2 is connected to the inlet of the first heat exchange channel, and the water is initially temperature-controlled through the first heat exchange channel to provide basic conditions for subsequent temperature adjustment. The second heating device 4 is controlled to operate at high power to heat the water passing through it to a boiling state. The high-temperature water passes through the second heat exchange channel and exchanges heat with the water in the first heat exchange channel, so that the outlet water temperature reaches the appropriate cooked water standard.

[0099] In this step, the temperature change of water flow in different areas 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 channel reaches the preset cooked water standard. According to the detection results, the power output of the first heating device 2 can be dynamically adjusted to further optimize the energy efficiency and water quality to meet the diverse drinking water needs of users. It is also possible to reasonably utilize the energy in the heat exchange process, reduce the energy consumption of the heating process, and improve the efficiency of the whole machine.

[0100] As a specific optional control method, when the cooked water pipeline machine is in the cooked water mode, step 200 in the control method specifically includes steps 210 to 230.

[0101] Step 210: Acquire the initial temperature T of the water in the second heat exchange channel. The initial temperature T of the water stored in the second heat exchange channel is detected by a temperature sensor, and the temperature value is compared with a preset threshold in subsequent steps as a basis for subsequent control.

[0102] Step 220: If the initial temperature T is lower than the first preset temperature T1, in the first stage, the first heating device 2 is controlled to heat the water passing through it to the second preset temperature T2. In the second stage, the first heating device 2 is controlled to heat the water passing through it to the third preset temperature T3, T3≤T1≤T2.

[0103] 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 low, which may cause the temperature of the first cup of water to be low. Therefore, the heating operation needs to be performed in stages. In the first stage, the first heating device 2 is controlled to work and heat the water passing through it to the second preset temperature T2, where T2>T1. By flowing the heated water into the first heat exchange channel, heat is directly exchanged with the low-temperature water stored in the second heat exchange channel to increase the temperature of the water stored in the second heat exchange channel. In the second stage, when the water temperature in the second heat exchange channel gradually rises and the cold water is drained, the working state of the first heating device 2 is adjusted to heat the water passing through it to the third preset temperature T3, where T3≤T1. The operation at this stage ensures that the water temperature entering the heat exchanger 3 is adapted to the subsequent heat exchange requirements, creating conditions for the cooked water process. The running time of the first stage is the preset time, and then it 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 outlet speed of the water outlet component are determined by the product parameters of the cooked 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 it may fluctuate slightly up or down. Technical personnel in this field can make specific selections and settings as needed.

[0104] Step 230: If the initial temperature T is not lower than the first preset temperature T1, the first heating device 2 is controlled 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 water temperature stored in the second heat exchange flow channel is close enough to the required temperature of cooked water. At this time, the first heating device 2 can be directly controlled to heat the water passing through it directly to the third preset temperature T3, avoiding unnecessary staged heating operations and improving water output efficiency.

[0105] This control logic can solve the problem of low outlet temperature of the first cup of water. Through staged heat regulation, it can prioritize increasing the temperature of the water stored in the second heat exchange channel to prevent cold water from flowing out directly and affecting the user experience. It can also avoid overheating while ensuring the outlet temperature of the first cup of water, reduce energy consumption, and shorten the waiting time for water output.

[0106] In some embodiments, the cooked water pipeline machine includes a first control valve 6, the inlet of the first control valve 6 is connected to the outlet of the first heating device 2, the first outlet of the first control valve 6 is connected to the water outlet component 5, and the second outlet of the first control valve 6 is connected to the inlet of the first heat exchange flow channel; the control method also includes: if the cooked water pipeline machine is in normal temperature water mode or boiling water mode, controlling the inlet of the first control valve 6 to be connected to the first outlet of the first control valve 6; if the cooked water pipeline machine is in cooked water mode, controlling the inlet of the first control valve 6 to be connected to the second outlet of the first control valve 6.

[0107] In the normal temperature water mode or the boiling water mode, the user needs normal temperature water or boiling water without heat exchange. The first control valve 6 is controlled to switch to a state where the inlet and the first outlet are connected. After the water flows through the first heating device 2, it directly flows to the water outlet component 5 through the first outlet of the first control valve 6 to complete the water supply, meet the user's needs for normal temperature water or boiling water, simplify the water path, and increase the water outlet speed.

[0108] In the cooked water mode, the user needs cooked water that has been temperature-controlled by heat exchange, and the first control valve 6 is controlled to switch to a state where the inlet and the second outlet are connected. After the water flows through the first heating device 2, it enters the first heat exchange channel through the second outlet of the first control valve 6. After heat exchange with the high-temperature water in the second heat exchange channel in the first heat exchange channel, the water flow is temperature-controlled to the cooked water temperature required by the user, and finally enters the water outlet component 5 through the outlet of the heat exchanger 3 to complete the water supply.

[0109] This control method accurately controls the water flow path through the two connected states of the first control valve 6 to adapt to the diverse needs of normal temperature water, boiling water and cooked water modes. In normal temperature water mode or boiling water mode, the water path is simplified and the waiting time is reduced. In cooked water mode, the water temperature is intelligently adjusted through heat exchange to avoid the outlet water temperature being too high or too low. The dynamic adjustment of the water flow path can reduce energy waste, reduce heat loss, avoid unnecessary heat exchange processes in boiling water mode or cooked water mode, and improve overall efficiency.

[0110] In some embodiments, the control method further includes: if the cooked water pipeline machine is in normal temperature water mode, controlling the first heating device 2 not to heat the water flowing through it. In normal temperature water mode, the user demand is unheated water, and normal temperature water in the water tank module 1 is directly provided, while reducing energy consumption. Water enters the first heating device 2 from the water tank body 101 through the driving pump 1022, flows out directly through the interior without heating, and enters the water outlet component 5 through the first outlet of the first control valve 6 to complete the water supply. Stopping the heating function of the first heating device 2 avoids unnecessary energy consumption, and flows directly to the water outlet component 5, shortening the water supply time. In normal temperature water mode, the first heating device 2 stops working, which also helps to extend the service life of the equipment.

[0111] In some embodiments, the control method further includes: if the cooked water pipeline machine is in boiling water mode, controlling the first heating device 2 to heat the water flowing through it to a boiling state. In boiling water mode, the user's demand is to directly output boiling water to ensure that the water temperature meets the drinking standard. Water is transported from the water tank module 1 to the first heating device 2 through the driving pump 1022. The first heating device 2 heats the water flow to a boiling state. After the heating is completed, the water flows through the first outlet of the first control valve 6 to the water outlet component 5, and is finally supplied to the user. It can quickly provide 100°C boiling water, which is suitable for brewing tea, coffee and other scenes, and reduces waiting time.

[0112] Some embodiments in this specification are described in a progressive or parallel manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referenced to each other.
