Technical Field
[0001] This utility model relates to the field of hydraulic module technology, and in particular to an integrated hydraulic module for central hot water supply using an air source heat pump. Background Technology
[0002] The air-source heat pump water module is a key component of an air-source heat pump system. It operates based on the principle of air-source heat pumps, heating or cooling the circulating water through refrigerant circulation and heat exchange with water in the condenser. It mainly consists of a heat exchanger, water pump, expansion tank, and control components. It can provide large-area heating and cooling in commercial settings and supply constant-temperature water in industrial applications, making its applications very wide-ranging. In residential settings, it can be used for both heating and hot water supply.
[0003] An air-source heat pump hydraulic module typically consists of a heat exchanger, a water pump, an expansion tank, and control components, utilizing a reverse Carnot cycle. First, heat is absorbed from the air to vaporize the refrigerant, which is then compressed into a high-temperature, high-pressure gaseous state by the compressor. Next, heat is exchanged with water in the condenser, heating the water and liquefying the refrigerant. Then, the pressure is reduced through the expansion valve, and heat is absorbed again in the evaporator, thus completing the cycle. The water pump drives the water to circulate within the system.
[0004] In existing technologies, some air source heat pump hydraulic modules still use traditional flange pipe connections, which cannot guarantee that there will be no leakage during pipe connections. This not only increases the safety hazard of leakage during installation and maintenance, but also causes the water flow in the equipment to be unstable due to continuous leakage. Therefore, an integrated hydraulic module for central hot water in air source heat pumps is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an integrated hydraulic module for central hot water supply using an air source heat pump, which aims to improve the problem of leakage during pipe connection in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An integrated hydraulic module for central hot water supply using an air-source heat pump includes a housing. Two input pipes are fixedly connected to the outside of the housing. A concave tube is fixedly connected to the end of each input pipe away from the housing. A spring is fixedly connected to the inner wall of the concave tube. A retaining ball is fixedly connected to the end of the spring away from the concave tube. A limiting plate is movably connected to the end of the retaining ball away from the spring. A top column is fixedly connected to the outside of the top column. A retaining pad is fixedly connected to the outside of the concave tube. A retaining ring is fixedly connected to the outside of the retaining ring. A rotating tube is slidably connected to the outside of the retaining ring. A fixing assembly for fixing subsequent components is movably connected to the inner wall of the rotating tube. A shock-absorbing assembly for damping subsequent components is fixedly connected to the inner wall of the housing.
[0008] As a further description of the above technical solution:
[0009] The fixing assembly includes two protruding tubes, and springs are fixedly connected to the inner walls of the two protruding tubes. A retaining ball is fixedly connected to the end of the springs away from the protruding tubes. An output tube is fixedly connected to the outside of the protruding tubes, and the end of the protruding tubes away from the output tubes is movably connected to the inner wall of the rotating tube.
[0010] As a further description of the above technical solution:
[0011] The shock absorption assembly includes multiple support frames, each with a rubber column fixedly connected to its inner wall. A fixing pin is fixedly connected to the inner wall of each rubber column, and a gasket is fixedly connected to the outside of each fixing pin. The multiple support frames are externally fixedly connected to the inner wall of the housing.
[0012] As a further description of the above technical solution:
[0013] The fixing pin is externally fixedly connected to a fixing frame, the fixing frame is externally fixedly connected to a water pump, and the inner wall of the box is fixedly connected to a water tank.
[0014] As a further description of the above technical solution:
[0015] The limiting disc is externally slidably connected to the inner wall of the concave tube, and the top column is externally slidably connected to the inner wall of the concave tube.
[0016] As a further description of the above technical solution:
[0017] The outer side of the second retaining ball is slidably connected to the inner wall of the convex tube, and the outer side of the second retaining ball is in contact with the outer side of the top column;
[0018] As a further description of the above technical solution:
[0019] The top post is slidably connected to the inner wall of the convex tube, and the outer side of the pad is in contact with the inner wall of the concave tube.
[0020] As a further description of the above technical solution:
[0021] The outer side of the convex tube is in contact with the inner wall of the concave tube, and the end of the pad away from the concave tube is in contact with the outer side of the convex tube.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, a rotating tube connects a concave tube and a convex tube. The top column pushes the second locking ball to move, while the limiting plate pushes the first locking ball towards the first spring. At this time, the locking pad will be locked between the concave tube and the convex tube, forming a gap. The top column has a groove, so water can pass through the inside of the top column, making the concave tube and the convex tube connected. Because the first and second locking balls are squeezed by the first and second springs, when the rotating tube is unscrewed, the first and second springs will push the first and second locking balls to continue to be locked inside the concave tube and the convex tube, preventing water flow and blocking the water flow channel. This prevents accidental water leakage, reduces safety hazards, and improves work efficiency.
[0024] 2. In this utility model, vibration will occur during the operation of the water pump. As a power component, the water pump will inevitably generate vibration during operation. At this time, the rubber column fixed in the support frame will prevent the vibration generated by the support frame from resonating with the housing due to its characteristics. The rubber column uses its own elasticity to absorb and convert the received vibration energy, preventing the vibration from being transmitted to the housing and causing resonance, thus achieving the effect of shock absorption. At the same time, a gasket is connected above the rubber column, which protects the rubber column and prevents unnecessary wear. The gasket can reduce the friction between the rubber column and other components when the rubber column is subjected to vibration and compression, preventing excessive wear on the surface of the rubber column, thereby ensuring that the shock absorption component can play a stable shock absorption role for a long time and extending the service life of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 2 This utility model provides an embodiment of an integrated hydraulic module for central hot water supply using an air-source heat pump. The module includes a housing 1, which serves as the outer shell of the entire module, protecting the internal components and providing a stable installation environment to prevent interference from external factors. Two input pipes 2 are fixedly connected to the outside of the housing 1. These input pipes 2 facilitate the smooth entry of external water sources and other media into the hydraulic module, serving as a crucial channel for media input and laying the foundation for subsequent water circulation operations. A concave pipe 3 is fixedly connected to the end of each input pipe 2 furthest from the housing 1. The concave pipe 3 acts as a connecting component; its unique shape and structure allow for better cooperation with other components to achieve connection and water flow control functions, preparing for subsequent assembly and water flow operation.
[0033] A spring 4 is fixedly connected to the inner wall of the concave tube 3. Spring 4 has good elasticity and, during the connection and disconnection of the hydraulic module, can control the position of the connected retaining ball 5 through its own expansion and contraction, thereby controlling the water flow channel and playing a crucial auxiliary role. The end of spring 4 furthest from concave tube 3 is fixedly connected to retaining ball 5. Retaining ball 5 moves within concave tube 3 under the action of spring 4, and can be locked in a specific position. It works with other components to block or open the water flow, making it an indispensable part of the water flow control mechanism. The end of retaining ball 5 furthest from spring 4 is movably connected to a limiting plate 6. Limiting plate 6 restricts the movement range of retaining ball 5, ensuring that it moves within a reasonable range, guaranteeing the normal operation of the entire connection and water flow control mechanism, and preventing abnormal situations such as excessive displacement of retaining ball 5. The end of the limiting plate 6 away from the ball 5 is fixedly connected to the top post 7. The top post 7 moves with the movement of the limiting plate 6. Its unique structure, such as the groove, plays a key role in the entire water flow process, allowing water to pass through its interior to achieve communication between the concave tube 3 and other components.
[0034] Reference Figure 2 The top column 7 is externally fixedly connected with a retaining pad 8. After the top column 7 is moved into place, the retaining pad 8 is engaged between the recessed tube 3 and other connected components, creating a suitable gap. This helps to achieve relative fixation between components and ensures that water flows through in the predetermined manner, preventing leaks. The top column 7 is externally slidably connected to the inner wall of the recessed tube 3. This sliding connection ensures that the top column 7 can move smoothly within the recessed tube 3, thereby cooperating with other components to complete corresponding operations and ensuring the smooth connection and water flow control functions of the entire hydraulic module. The recessed tube 3 is externally fixedly connected with a retaining ring 12. The retaining ring 12 provides a stable sliding connection base for the rotating tube 13, allowing the rotating tube 13 to rotate around it. During rotation, it can accurately drive the relevant components to cooperate, playing a stabilizing role in the entire connection structure. The external sliding connection of the retaining ring 12 is a rotating tube 13. The rotating tube 13 controls the connection and disconnection of the concave tube 3 and the convex tube 9 by rotating. It is the key operating component for switching the connection of components in the entire hydraulic module. The on / off state of the internal water flow channel can be changed by manually rotating it.
[0035] The inner wall of the rotating tube 13 is movably connected to a fixing assembly for securing subsequent components. With the cooperation of the rotating tube 13, the fixing assembly can accurately connect and fix with components such as the concave tube 3, ensuring the robustness of the entire hydraulic module connection and preventing loosening of components during water flow, thus ensuring stable water flow between components. The fixing assembly includes two convex tubes 9. As an important part of the fixing assembly, the two convex tubes 9 are structurally compatible with the concave tube 3 and, through the cooperation of internal components, achieve connection with the concave tube 3 and control of water flow. They are key components in the connection structure, playing a crucial role in connecting the upper and lower parts. The inner walls of both convex tubes 9 are fixedly connected to springs 10. Springs 10 are also elastic; during the connection or disconnection of the convex tube 9 and the concave tube 3, they expand and contract with the movement of the retaining ball 11, thus supporting and resetting the retaining ball 11, ensuring the reliability and operability of the entire connection structure. The end of spring 2 10 away from the convex tube 9 is fixedly connected to ball 2 11. Ball 2 11 moves inside the convex tube 9 under the action of spring 2 10 and interacts with components such as top column 7 to jointly control the opening and closing of the water flow channel between concave tube 3 and convex tube 9. It is a key link in realizing water flow control.
[0036] Reference Figures 3 to 4 The external of the convex pipe 9 is fixedly connected to an output pipe 14. The output pipe 14 is the outlet channel for the medium processed by the hydraulic module, which can smoothly transport the processed hot water and other media to the external location where they are needed, such as to the water terminal, thus realizing the output function of the entire hydraulic module. The end of the convex pipe 9 away from the output pipe 14 is movably connected to the inner wall of the rotating pipe 13. This connection method allows the convex pipe 9 to accurately cooperate with the concave pipe 3 under the rotation of the rotating pipe 13, completing the connection and disconnection action, and realizing the switching of the water flow channel. The inner wall of the housing 1 is fixedly connected to a vibration damping component to reduce the vibration of subsequent components. The vibration damping component can effectively reduce the impact of the vibration generated by the pump 20 and other operating components on the housing 1 and the entire hydraulic module, ensuring that the module is more stable during operation and reducing noise and component wear caused by vibration. The vibration damping component includes multiple support frames 15, which serve as the basic support structure of the vibration damping component. They are fixed to the inner wall of the housing 1, can support components such as rubber columns 16, and connect these components to the housing 1, playing the role of transmitting and dispersing vibration.
[0037] Rubber columns 16 are fixedly connected to the inner walls of multiple support frames 15. During the operation of the water pump 20, vibrations occur. The rubber columns 16, fixed within the support frames 15, prevent resonance between the vibrations generated by the support frames 15 and the housing 1 due to their elasticity, thus achieving a vibration damping effect. They are the core components for achieving this damping function, absorbing and buffering vibration energy through their elastic deformation. Fixing pins 17 are fixedly connected to the inner walls of the rubber columns 16, further securing and supporting them to ensure that the rubber columns 16 do not shift or experience other abnormalities when subjected to vibration and impact, thus guaranteeing the stable operation of their vibration damping function.
[0038] The fixing pin 17 is externally fixed with a washer 18, which protects the rubber column 16 and prevents unnecessary wear. It reduces friction damage to the surface of the rubber column 16 when it comes into contact with other components or is subjected to vibration and pressure, extending its service life and indirectly ensuring the long-term effectiveness of the shock absorption assembly. Multiple support frames 15 are externally fixed to the inner wall of the housing 1. This fixing method allows the entire shock absorption assembly to be securely installed inside the housing 1, thereby better performing its shock absorption function and ensuring that all components inside the housing 1 operate in a relatively stable environment.
[0039] Reference Figures 3 to 4 The fixing pin 17 is externally fixedly connected to a fixing frame 19, which further supports and fixes the fixing pin 17 and other components, making the entire shock-absorbing structure more stable and ensuring that components such as the rubber column 16 can accurately perform their shock-absorbing function. It plays a role in strengthening and stabilizing the entire shock-absorbing assembly structure. The fixing frame 19 is externally fixedly connected to a water pump 20, which is a key power component in the entire hydraulic module used to drive water circulation and other operations. The vibration generated during its operation is buffered and eliminated by the shock-absorbing assembly, ensuring the stability of the entire module's operation. The inner wall of the housing 1 is fixedly connected to a water tank 21, which is used to store hot water and other media. It plays a buffering and transfer role in the heating process of the air source heat pump and the water flow regulation process of the hydraulic module, ensuring a stable supply of hot water to meet subsequent usage needs. It is an important storage link in the entire hot water supply system.
[0040] The limiting disc 6 is externally slidably connected to the inner wall of the concave tube 3. This slidable connection ensures that the limiting disc 6 can slide smoothly within the concave tube 3 as related components move, thereby driving components such as the top column 7 to accurately complete the corresponding operations, ensuring the normal realization of functions such as water flow control and component connection. The top column 7 is externally slidably connected to the inner wall of the convex tube 9, allowing the top column 7 to move smoothly within the convex tube 9, thus better cooperating with components such as the second locking ball 11 to achieve effective control of the water flow channel between the concave tube 3 and the convex tube 9, ensuring the normal operation of the water flow conduction and blocking functions of the entire hydraulic module. The second locking ball 11 is externally slidably connected to the inner wall of the convex tube 9. The second locking ball 11 can move reasonably within the convex tube 9 according to the extension and contraction of the second spring 10 and the pushing of the top column 7, thereby cooperating with other components to control the opening and closing of the water flow channel, which is an important detail in realizing water flow control. The outer surface of the second locking ball 11 is in contact with the outer surface of the top column 7. This contact relationship allows the top column 7 to directly push the second locking ball 11 when it moves, thereby triggering a series of component linkages, changing the state of the water flow channel, and realizing the conduction or blockage of water flow between the concave pipe 3 and the convex pipe 9.
[0041] Reference Figure 2 The top post 7 is externally slidably connected to the inner wall of the convex tube 9, ensuring the flexibility of the top post 7's movement within the convex tube 9. This allows it to accurately cooperate with components such as the retaining ball 11 to complete the corresponding water flow control actions, ensuring the accurate operation of the water flow control mechanism of the entire hydraulic module. The outer surface of the retaining pad 8 contacts the inner wall of the concave tube 3. This contact between the retaining pad 8 and the inner wall of the concave tube 3 creates a certain sealing and fixing effect, making the connection between the concave tube 3 and the convex tube 9 more stable and ensuring that the water flow passes through the predetermined path, avoiding leakage and other adverse conditions. The outer surface of the convex tube 9 contacts the inner wall of the concave tube 3. This contact method is the basis for the connection between the concave tube 3 and the convex tube 9. Through their tight contact and the cooperation of the internal components, the construction and control of the water flow channel are completed. This is the key contact form of the entire hydraulic module connection structure. The end of the gasket 8 away from the concave tube 3 is in contact with the outside of the convex tube 9. This contact relationship further strengthens the sealing and stability of the connection between the concave tube 3 and the convex tube 9, ensuring that there will be no loosening or leakage when water flows through, and ensuring the reliable operation of the entire hydraulic module.
[0042] Working principle: The concave tube 3 and convex tube 9 are connected by rotating the rotating tube 13. The top post 7 pushes the second locking ball 11 to move, while the limiting plate 6 pushes the first locking ball 5 towards the first spring 4. At this time, the locking pad 8 will be locked between the concave tube 3 and the convex tube 9 to form a gap. The top post 7 has a groove, so water can pass through the inside of the top post 7, making the concave tube 3 and the convex tube 9 connected. Because the first locking ball 5 and the second locking ball 11 are squeezed against the first spring 4 and the second spring 10, when the rotating tube 13 is unscrewed, the first spring 4 and the second spring 10 will push the first locking ball 5 and the second locking ball 11 to continue to be locked inside the concave tube 3 and the convex tube 9, so that the water flow cannot pass through and the water flow channel is blocked to prevent accidental water leakage.
[0043] Vibration occurs during the operation of the water pump 20. As a power component, the water pump 20 inevitably vibrates during operation. Due to its characteristics, the rubber column 16 fixed in the support frame 15 prevents the vibration generated by the support frame 15 from resonating with the housing 1. The rubber column 16 absorbs and converts the received vibration energy using its own elasticity, preventing the vibration from being transmitted to the housing 1 and causing resonance, thus achieving a shock absorption effect. At the same time, a gasket 18 is connected above the rubber column 16. The gasket 18 protects the rubber column 16 and prevents unnecessary wear. When the rubber column 16 is subjected to vibration and compression, the gasket 18 can reduce friction with other components, prevent excessive wear on the surface of the rubber column 16, extend the service life of the rubber column 16, and thus ensure that the shock absorption component plays a stable role in shock absorption for a long time, so that the entire hydraulic module can work continuously in a relatively stable operating environment.
