Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] In related technologies, common coupling tanks make it inconvenient for the heating system to vent air during the initial installation phase, which is detrimental to normal use later. In particular, the system heats up slowly in the initial stage of use, sometimes resulting in insufficient heating, making it difficult to quickly diagnose the cause of system failure.

[0040] As shown in Figure 1, in order to solve the above-mentioned technical problems, this application provides a coupling tank assembly 100. The coupling tank assembly 100 has a primary side inlet 111, a primary side outlet 122, a secondary side outlet 112, and a secondary side inlet 121. The primary side inlet 111 and the secondary side outlet 112 are connected, and the secondary side outlet 112 and the primary side inlet 111 are connected. The coupling tank assembly 100 can switch between at least a first connection mode and a second connection mode. In the first connection mode, the secondary side inlet 121 is only connected to the primary side outlet 122. In the second connection mode, the secondary side inlet 121 is connected to both the secondary side outlet 112 and the primary side outlet 122.

[0041] In these embodiments, the coupling tank assembly 100 includes a primary side inlet 111, a primary side outlet 122, a secondary side outlet 112, and a secondary side inlet 121.

[0042] The primary inlet 111 and the secondary outlet 112 are connected, and the secondary outlet 112 is also connected to the primary inlet 111. This can be understood as maintaining a continuous connection between the primary inlet 111 and the secondary outlet 112, and vice versa. The connection mode can be switched subsequently to control whether the secondary outlet 112 is connected to the secondary inlet 111.

[0043] First connectivity mode:

[0044] In this mode, the secondary side inlet 121 is connected only to the primary side outlet 122. This allows the high-temperature water flow from the primary side to flow directly to the secondary side, achieving so-called "hydraulic decoupling." This setup helps to quickly raise the system temperature and promotes the effective removal of gases from the system, resolving potential issues of insufficient heating and incomplete venting during initial use.

[0045] Second connectivity mode:

[0046] In this mode, the secondary side inlet 121 is connected not only to the primary side outlet 122, but also to the secondary side outlet 112, forming a local mixing loop. This configuration achieves "hydraulic coupling," allowing some of the secondary side return water to mix with the high-temperature water from the primary side, thereby helping to stabilize and control the water supply temperature.

[0047] It should be noted that for those skilled in the art, how to switch the control water circuit using valve components is a conventional and exemplary setup. In this embodiment, a bypass port can be provided at the secondary side outlet 112 to connect the secondary side inlet 121 and the primary side outlet 122, and a switching valve or flow regulating valve can be provided at the bypass port to achieve switching or flow regulation, thereby realizing the mode switching of the coupling tank assembly 100. Of course, the secondary side inlet 121 can also be connected to the secondary side outlet 112 through a switching valve or flow regulating valve, or the secondary side inlet 121 and the primary side outlet 122 can be directly connected, etc.

[0048] Therefore, by switching between these two modes, the coupling tank assembly 100 can dynamically adjust the water flow path within the system, optimizing system operating efficiency. Specifically, especially in the first connection mode, the elimination of the mixing step allows for faster heat transfer to the user side, quickly raising the system temperature. Furthermore, the water flow characteristics in this first connection mode help to more effectively remove air from the system, reducing the impact of air resistance on system performance.

[0049] Furthermore, by comparing temperature and pressure changes under different modes, it is easier to identify problems in the system (such as blockages or pump failures), thereby improving maintenance efficiency.

[0050] In some embodiments, the coupling tank assembly 100 includes a tank body 110 and an adjusting member 120. The tank body 110 has a cavity and an adapter 113. The cavity is connected to a primary side inlet 111, a secondary side outlet 112, and the adapter 113, respectively. The adjusting member 120 is connected to the tank body 110 and can adjust the opening of the adapter 113.

[0051] In these embodiments, the design of the coupling tank assembly 100 incorporates a more refined adjustment mechanism to enhance the system's flexibility and adaptability. The coupling tank assembly 100 is configured as follows:

[0052] Tank 110 is the core part of coupling tank assembly 100 and has an internal cavity. This cavity is connected to the primary side inlet 111, the secondary side outlet 112 and the adapter 113, respectively, so that water flow can be distributed and mixed between these interfaces.

[0053] The presence of adapter 113 allows for flexible path selection of water flow in different modes. By controlling the opening of adapter 113, precise adjustment of different water flow paths can be achieved, thereby optimizing system performance.

[0054] The regulating component 120 is connected to the tank body 110, and its main function is to adjust the opening of the adapter 113. By adjusting the opening of the adapter 113, the water flow distribution can be changed according to actual needs, thereby realizing the switching between the first connection mode and the second connection mode, or finding the most suitable operating state between the two modes.

[0055] In other words, when the opening degree of the control interface 113 controlled by the regulating element 120 is 0, the coupling tank assembly 100 is in the first connected state. When the opening degree of the control interface 113 controlled by the regulating element 120 is greater than 0, the coupling tank assembly 100 is in the second connected state.

[0056] For example, in this embodiment, the regulating element 120 is a flow regulating valve. Of course, in other embodiments, the regulating element 120 may also be a switching valve, a plug-in valve, a solenoid valve, etc.

[0057] Therefore, the adjusting component 120 can adjust the opening degree of the adapter 113 according to the actual operating conditions, so that the coupling tank assembly 100 can better adapt to different operating conditions. Furthermore, through precise control of the opening degree of the adapter 113, not only can functions such as rapid heating and effective exhaust be achieved, but also the system can be ensured to operate efficiently and stably under different load conditions.

[0058] In some embodiments, the regulating element 120 is configured as a three-way regulating valve having a pair of outlets and an inlet; wherein one outlet is connected to the primary side outlet 122, the other outlet is connected to the adapter 113, and the inlet is connected to the secondary side inlet 121.

[0059] In these embodiments, the coupling tank assembly 100 employs a three-way regulating valve as the regulating element 120, further refining the control of the water flow path and enhancing the system's flexibility and adaptability. The inlet of the three-way regulating valve is connected to the secondary side inlet 121, allowing water from the secondary side to enter the regulating valve.

[0060] Of the pair of outlets, one outlet is connected to the primary side outlet 122, and the other outlet is connected to the adapter 113. In this way, it is possible to flexibly control whether the water flowing in from the secondary side inlet 121 is directed to the primary side outlet 122 or redistributed through the adapter 113.

[0061] For ease of understanding, the first and second connection modes are defined using a definition adapted to a three-way control valve:

[0062] In the first connection mode, by adjusting the three-way regulating valve, the secondary side inlet 121 is connected only to the primary side outlet 122. This means that the water flow on the secondary side flows directly to the primary side outlet 122, eliminating the mixing process, achieving rapid heating, and helping to remove air from the system.

[0063] In the second connection mode, the three-way regulating valve is configured to connect the secondary side inlet 121 to both the secondary side outlet 112 (via adapter 113) and the primary side outlet 122. This creates a partial mixing loop, achieving hydraulic coupling. Part of the secondary side return water mixes with the high-temperature primary side water, thus helping to stabilize the supply water temperature.

[0064] For example, the three-way regulating valve can be an electric three-way regulating valve, a pneumatic three-way regulating valve, a manual three-way regulating valve, a ball three-way regulating valve, or a butterfly three-way regulating valve, etc.

[0065] In some embodiments, this application also provides a mixing device for a heating system. The mixing device includes a coupling tank assembly 100 and a pumping component 200. The coupling tank assembly 100 is configured as any of the coupling tank assemblies 100 described in the above embodiments. The pumping component 200 has a suction port and a drain port. The pumping component 200 is used to pump heating water. The suction port and the secondary side outlet 112 are connected.

[0066] These embodiments disclose an improved mixing device for a heating system, which not only includes the previously described coupling tank assembly 100 with multiple mode switching functions, but also integrates an extraction / extraction component 200. This aims to further optimize the performance of the heating system, particularly by providing a more efficient solution for mixing and removing air from the system.

[0067] The coupling tank assembly 100, based on the above embodiments, includes a primary side inlet 111, a primary side outlet 122, a secondary side outlet 112, and a secondary side inlet 121, and can switch between a first connection mode and a second connection mode. This allows for flexible adjustment of the water flow path according to actual needs, achieving functions such as rapid heating and effective venting, while simplifying the fault diagnosis process.

[0068] The extraction / discharge unit 200 is equipped with a suction port and a discharge port for pumping heating water. Specifically, the suction port is connected to the secondary side outlet 112. The main function of the extraction / discharge unit 200 is to assist the system in mixing water and removing air. By extracting water from the system and redistributing it, it helps to mix water of different temperatures more evenly, improving the overall thermal efficiency of the system; at the same time, it also helps to remove air from the system, reducing the impact of air resistance on system operation.

[0069] Therefore, the addition of the extractor 200 allows the system to more effectively mix water from different sources (such as primary side high-temperature water and secondary side return water), ensuring the stability and consistency of the supply water temperature and improving the heating effect. Clearly, the operation of the extractor 200 can more thoroughly remove air from the system, avoiding localized overheating or poor heat dissipation caused by air bubbles, thus helping to maintain the system's efficient operation.

[0070] Furthermore, in these embodiments, since the coupling tank assembly 100 has the aforementioned technical effects, the mixing device including the coupling tank assembly 100 should have the same technical effects, which will not be elaborated here.

[0071] In some embodiments, the mixing device further includes an integrated upper lever 300, which has an exhaust port, an upper lever inlet 310, and an upper lever outlet 320. The upper lever inlet 310, the upper lever outlet 320, and the exhaust port are connected, and the top of the exhaust port and the upper lever inlet 310 are connected.

[0072] In these embodiments, the mixing device is further equipped with an integrated upper lever 300, which aims to further enhance the system's venting function and ensure stable and efficient system operation.

[0073] The integrated upper bar 300 is located above the coupling tank assembly 100, and the exhaust port is located at the top of the integrated upper bar 300 and is connected to the upper bar inlet 310. This is to facilitate the exhaust of air from the system and avoid the reduction in thermal efficiency or other problems caused by air accumulation.

[0074] The upper inlet 310 is used to receive water flow from the system. It is connected to the vent, allowing water to flow through while also allowing air to rise and be discharged from the vent.

[0075] The upper bar outlet 320 is responsible for redirecting the treated water (such as venting) back into the system for continued recycling. The three (venting port, upper bar inlet 310, and upper bar outlet 320) are connected, forming an effective water flow channel and facilitating air removal.

[0076] Therefore, the integrated upper vent 300 design allows air in the system to be more easily concentrated in one place and discharged through the exhaust port. This helps solve common problems in traditional heating systems, such as poor heat dissipation or localized overheating caused by air accumulation. By effectively removing air from the system, not only can heat exchange efficiency be improved, but system instability caused by air resistance can also be reduced, ensuring the long-term stable operation of the heating system.

[0077] It should be noted that the exhaust port is usually equipped with a valve plug, exhaust valve or on / off valve to control the opening and closing of the exhaust port.

[0078] In some embodiments, the integrated upper lever 300 also has an upper lever cavity, with an upper lever inlet 310 and an upper lever outlet 320 respectively connected to the upper lever cavity. The top of the upper lever cavity is defined to form a gas storage section, which can store gas, and the exhaust port is connected to the gas storage section.

[0079] In these embodiments, the integrated upper lever 300 is refined to include a dedicated gas storage section for storing the gas separated from the water flow and discharging it through an exhaust port. This design optimizes the system's automatic venting function, improving overall efficiency and stability.

[0080] The upper bar inlet 310 and upper bar outlet 320 are respectively connected to the upper bar cavity, allowing water to flow smoothly in and out.

[0081] A gas storage section is defined at the top of the upper cavity, specifically designed to collect the gas separated from the water flow. This gas storage section helps ensure that the gas is effectively concentrated in a specific area, preventing it from re-mixing into the water flow, thereby improving the efficiency of air removal.

[0082] The exhaust port is directly connected to the gas storage section, allowing the gas accumulated in the gas storage section to be safely discharged out of the system through the exhaust port.

[0083] When water flows into the upper cylinder cavity through the inlet 310, the air entrained in it naturally rises to the top of the upper cylinder cavity, i.e., the air storage section, due to factors such as slower flow velocity and changed flow direction. The air accumulated in the air storage section can then be discharged from the system through the vent, preventing problems caused by air stagnation in the heating system, such as air resistance or reduced heat exchange efficiency. The treated water then continues to flow out through the outlet 320 of the upper cylinder, returning to the system circulation.

[0084] In some embodiments, the upper bar inlet 310 and the upper bar outlet 320 are respectively connected to the bottom of the upper bar cavity.

[0085] In these embodiments, the upper lever inlet 310 and upper lever outlet 320 are respectively connected to the bottom of the upper lever cavity, which helps to optimize the water flow path and more effectively separate air in the water flow, ensuring stable system operation. The upper lever inlet and outlet 320 are both located at the bottom of the upper lever cavity, allowing the incoming water to enter the cavity directly from the bottom, reducing disturbance to the gas already accumulated in the top gas storage section, and helping the gas to remain more stably within the gas storage section.

[0086] Clearly, when water enters the upper cylinder cavity through the upper cylinder inlet 310, gravity causes the water to fill the bottom of the cavity, while lighter air rises to the air storage section at the top. The treated water then flows out through the upper cylinder outlet 320, continuing to participate in the system circulation. As water continues to flow in and out, any entrained gas naturally rises to the air storage section at the top, preventing gas from mixing back into the main water flow. The accumulated gas can then be discharged from the system through the exhaust port connected to the air storage section.

[0087] In some embodiments, the mixing device further includes a temperature detection element 400, which is disposed on the integrated upper bar 300 and is used to obtain the temperature of the heating water flowing through the upper bar inlet 310.

[0088] In these embodiments, the mixing device is further equipped with a temperature detection element 400, which is set on the integrated upper bar 300 to monitor the temperature of the heating water flowing through the upper bar inlet 310. This allows for real-time monitoring of water temperature changes in the system, which helps to more accurately control and regulate the operating status of the heating system.

[0089] The temperature sensor 400 is mounted on the integrated upper bar 300. Specifically, it is used to acquire the temperature of the heating water flowing through the upper bar inlet 310. In other words, by monitoring the water flow temperature in real time, the temperature sensor 400 provides key data to the control system. This data can be used to adjust the operating parameters of the heating system, such as adjusting the working mode of the coupling tank assembly 100 and optimizing the operation of the extraction and discharge components 200.

[0090] It should be noted that, especially for heat sources such as boilers or wall-mounted boilers, energy saving and consumption reduction can be achieved by switching modes.

[0091] For example, the temperature sensing element 400 may be a thermometer, a temperature gauge, or a temperature sensor, etc.

[0092] In some embodiments, an exhaust component 500 is provided at the exhaust port, which is used to control the gas emission from the exhaust port.

[0093] In these embodiments, the exhaust component 500 is installed at the exhaust port and is mainly used to control the amount and timing of gas discharged from the gas storage section of the integrated upper lever 300. The exhaust process can be started or stopped automatically or manually according to pressure changes or other preset conditions within the system.

[0094] For example, the venting component 500 includes, but is not limited to, automatic venting valves and manual venting valves. Automatic venting valves can automatically open or close according to the pressure in the system to release accumulated air; while manual venting valves require manual intervention to vent air.

[0095] It should be noted that the exhaust component 500 allows for precise control of the exhaust process, ensuring that exhaust only occurs when there is sufficient air buildup in the system and venting is necessary. This avoids unnecessary moisture loss and ensures optimal system operation.

[0096] For example, the exhaust valve can be an automatic exhaust valve, a manual exhaust valve, a combination exhaust valve, etc. Of course, it can also be a switch valve, etc.

[0097] In some embodiments, this application also provides a heating system, which includes a mixing device as described in any of the above embodiments, a wall-hung boiler heat source, and a hot water pipe network. The water supply port and primary side inlet 111 of the wall-hung boiler heat source are connected, and the return port and primary side outlet 122 of the wall-hung boiler heat source are connected. The pipe network inlet and drain port of the hot water pipe network are connected, and the pipe network return port and secondary side inlet 121 of the hot water pipe network are connected.

[0098] These embodiments disclose a complete heating system that not only includes the mixing device described in detail earlier, but also integrates a wall-mounted boiler as the heat source and a hot water pipe network. The aim is to improve the efficiency and stability of the entire system by optimizing the heat source supply and water flow distribution. The mixing device includes a coupling tank assembly 100, an exhaust assembly 200, an integrated upper lever 300 (with venting function and a temperature detection element 400), and an exhaust element 500 for controlling gas emissions. These components work together to achieve efficient water flow management and air removal, ensuring stable system operation.

[0099] The water supply port of the wall-hung boiler is connected to the primary side inlet 111 of the mixing device, providing high-temperature hot water as the heat source. The return port is connected to the primary side outlet 122, receiving the low-temperature return water after heat exchange and returning it to the wall-hung boiler for reheating. Of course, in other embodiments, the heat source can also be a boiler, etc.

[0100] The hot water pipe network inlet is connected to the drain outlet of the extraction unit 200, receiving treated hot water (such as for mixing and venting) for user use. The pipe network return outlet is connected to the secondary side inlet 121, sending used cold or low-temperature water back to the mixing device for reheating and recycling. The hot water pipe network is responsible for distributing heated water to various spaces requiring heating and recovering cooled water back into the system for continued circulation. The hot water pipe network includes, but is not limited to, pipes and radiators laid on the ground.

[0101] Furthermore, in these embodiments, since the mixing device has the aforementioned technical effects, the heating system including the mixing device should have the same technical effects, which will not be elaborated further here.

[0102] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0104] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
