[0031] Please see Figures 1 to 5The present invention provides a hydraulic module 100 including a water pump 28, a pipe and a snap-fit ​​component 12. The water pump has one of a first connecting part 14 and a second connecting part 20. The first connecting part 14 has an insertion space 16 and a first slot 18 communicating with the insertion space 16. The pipe has the other of a first connecting part 14 and a second connecting part 20. The outer side of the second connecting part 20 has a second slot 22. The second connecting part 20 is inserted into the insertion space 16. The snap-fit ​​component 12 is detachably passed through the first slot 18 and the second slot 22 so that the water pump 28 and the pipe are fixedly connected through the first connecting part 14 and the second connecting part 20.

[0032] In the aforementioned hydraulic module 100, the snap-fit ​​component 12 is detachably inserted through the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22 so that the water pump 28 and the pipeline are fixedly connected through the first connecting part 14 and the second connecting part 20. Thus, the water pump 28 and the pipeline can be disassembled and assembled by detaching and assembling the snap-fit ​​component 12, which can reduce the operating space to a certain extent and reduce the difficulty of replacing parts after sales.

[0033] Specifically, in one embodiment, the hydraulic module 100 can be applied to a heating unit, which can be a heat pump type heating unit. Please refer to... Figure 1 In one embodiment, the hydraulic module 100 may include a heat exchanger 26, a water pump 28, and pipes. The pipes can connect the heat exchanger 26 and the water pump 28 so that water can flow between the heat exchanger 26 and the water pump 28. Thus, the refrigerant can exchange heat with the water through the heat exchanger 26, raising the water temperature to form high-temperature water. The high-temperature water can be sent into the indoor unit driven by the water pump 28. After exchanging heat with the heat exchanger of the indoor unit, it forms low-temperature water. The low-temperature water can be sent into the heat exchanger 26 driven by the water pump 28, and then exchange heat with the refrigerant to form high-temperature water. This cycle continues, thereby enabling the indoor unit to raise the indoor ambient temperature.

[0034] In related technologies, the pump and pipeline of a hydraulic module are typically connected by threads. Connecting the pump and pipeline requires using a wrench to rotate the connector on the pump or pipeline, establishing a threaded connection and securing the two components. Sufficient space needs to be provided for operating the wrench. However, when the hydraulic module is installed in a user's building, the operating space is often limited, making it difficult to operate the wrench for component replacement during after-sales service, leading to difficulties in after-sales support. Furthermore, the direction of wrench rotation is uncertain when disassembling and assembling the pump, requiring repeated attempts, complicating installation and resulting in lengthy after-sales service times.

[0035] In this embodiment of the invention, the snap-fit ​​component 12 is detachably inserted through the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22. When disassembling the water pump 28 and the pipe, the snap-fit ​​component 12 can be removed, thereby releasing the connection lock between the water pump 28 and the pipe, allowing the water pump 28 and the pipe to be separated. During installation, the second connecting part 20 can be inserted into the insertion space 16 of the first connecting part 14, aligning and communicating the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22. Then, the snap-fit ​​component 12 is snapped into the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22, fixing the first connecting part 14 and the second connecting part 20 together, thus fixing the water pump 28 and the pipe together. In summary, this reduces the operating space to a certain extent, making after-sales component replacement easier, and the entire process is essentially tool-free. The snap-fit ​​component 12 includes, but is not limited to, snap-fit ​​pins (…). Figure 4 ),card( Figure 5 )wait.

[0036] In the illustrated embodiment, the water pump 28 is provided with a first connecting portion 14, and the pipe is provided with a second connecting portion 20. In other embodiments, the water pump 28 may be provided with a second connecting portion 20, and the pipe may be provided with a first connecting portion 14.

[0037] In some implementations, please refer to Figures 1 to 3 The pipe includes a body 34 and a fitting. The body 34 is connected to the fitting, and the fitting has a first connecting part 14 and a second connecting part 20.

[0038] This improves the compatibility between the water pump 28 and the pipeline.

[0039] Specifically, the accessories can have corresponding types or sizes according to the dimensions or types of the body and the connection, so that the body 34 can be connected to the water pump in a suitable manner, and the connection between the water pump 28 and the pipeline can be more stable.

[0040] In one implementation, please refer to Figure 2 The main body 34 can be a connecting pipe, and the water pump 28 includes a connector with a first connecting part 14. The diameter of the connecting pipe is small, while the diameter of the insertion space 16 of the first connecting part 14 is large. The accessories include a first accessory 32, which can be connected to one end of the connecting pipe. The first accessory 32 has a second connecting part 20 and a through hole. The diameter of the through hole is slightly larger than the diameter of the connecting pipe, and one end of the connecting pipe can be inserted into the through hole. The outer diameter of the first accessory 32 is slightly smaller than the diameter of the insertion space 16. One end of the connecting pipe is connected to the first accessory 32 to form a pipe. The first accessory 32 can be inserted into the insertion space 16 of the first connecting part 14, so that the first slot 18 of the first connecting part 14 is aligned and connected with the second slot 22 of the second connecting part 20. Then, the snap-fit ​​member 12 is inserted into the first slot 18 and the second slot 22, thereby fixing the connection between the first connecting part 14 and the second connecting part 20.

[0041] In some embodiments, the body 34 is connected to the fittings by welding.

[0042] Therefore, the connection method between the main body and accessories can reduce gaps and make it more secure.

[0043] Specifically, the body and accessories can be made of metal, and the body and accessories are welded together, so that different types or sizes of accessories can be used to connect the body 34 to the water pump in a way that is compatible with it. Figure 2 This reduces gaps in the connection and improves the tightness of the connection.

[0044] In some implementations, please refer to Figure 2 and Figure 3 The second connecting part 20 is provided with at least one limiting groove 42, which is separated from the second slot 22. The hydraulic module 100 includes at least one sealing ring 44, each sealing ring 44 is embedded in a corresponding limiting groove 42, and the sealing ring 44 seals the connection between the first connecting part 14 and the second connecting part 20.

[0045] This improves the sealing performance of the connection between the water pump 28 and the pipeline.

[0046] Specifically, each sealing ring 44 is embedded in a corresponding limiting groove 42, so that the sealing ring 44 can be limited by the limiting groove 42, and the position of the sealing ring 44 will not change or is not easy to change, which reduces the occurrence of sealing failure or reduced sealing performance due to the displacement of the sealing ring 44 to a certain extent.

[0047] The number of sealing rings 44 and limiting grooves 42 can be determined according to specific requirements (such as pressure requirements). Figure 2 In the middle, the water pump 28 is sealed to the pipeline through two sealing rings 44, and the two sealing rings 44 are respectively embedded in the two limiting grooves 42.

[0048] exist Figure 2 In the illustrated embodiment, the water pump 28 includes a first connector 46 and a second connector 48, a first connecting portion 14 is disposed at the first connector 46 and the second connector 48, and the pipeline includes a first pipeline 50 and a second pipeline 52. A second connecting portion 20 is disposed at one end of the first pipeline 50 and one end of the second pipeline 52. The second connecting portion 20 of the first pipeline 50 is sealed to the first connecting portion 14 of the first connector 46 by two sealing rings 44. The second connecting portion 20 of the second pipeline 52 is sealed to the first connecting portion 14 of the second connector 48 by two sealing rings 44.

[0049] Optionally, in Figure 2In this configuration, the first connector 46 is the outflow connector of the water pump 28, and the second connector 48 is the inflow connector of the water pump 28. Optionally, in one embodiment, the first connector 46 is the inflow connector of the water pump 28, and the second connector 48 is the outflow connector of the water pump 28. The hydraulic module 100 may include a housing 68, and the other end of the first pipe 50 may pass through the housing 68.

[0050] In one example, the sealing ring 44 can be a rubber ring or a silicone ring.

[0051] In some implementations, please refer to Figure 2 and Figure 3 The sealing ring 44 is interference-fitted between the first connecting part 14 and the second connecting part 20.

[0052] This improves the sealing performance between the first connecting part 14 and the second connecting part 20.

[0053] Specifically, the sealing ring 44 is sandwiched between the outer wall of the second connecting portion 20 and the inner wall of the first connecting portion 14, causing the sealing ring 44 to undergo a certain degree of elastic deformation under the compression of the first connecting portion 14 and the second connecting portion 20. On the one hand, the elastically deformed sealing ring 44 can provide a larger contact area with the first connecting portion 14 and the second connecting portion 20. On the other hand, the elastically deformed sealing ring 44 can form a tighter contact with the first connecting portion 14 and the second connecting portion 20, thereby improving the sealing performance between the first connecting portion 14 and the second connecting portion 20, and improving the pressure-bearing performance between the first connecting portion 14 and the second connecting portion 20. Furthermore, the elastically deformed sealing ring 44 can fill the limiting groove 42 more tightly, thereby further reducing the occurrence of displacement of the sealing ring 44.

[0054] In some implementations, please refer to Figure 2 and Figure 3 The sealing ring 44 is an O-ring 44.

[0055] Therefore, O-ring 44 can provide better sealing performance.

[0056] Specifically, the O-ring 44 has an O-shaped or circular cross-section. When the O-ring 44 is compressed by the first connecting part 14 and the second connecting part 20, it can extend and deform along the inner wall of the first connecting part 14 and the outer wall of the second connecting part 20, thereby increasing the contact area and bonding force between the O-ring 44 and the first connecting part 14 and the second connecting part 20, thus improving the sealing performance.

[0057] In some implementations, please refer to Figure 4 and Figure 5The snap-fit ​​component 12 includes two snap-fit ​​arms 54 and a connecting arm 56. The two snap-fit ​​arms 54 are respectively connected to the two opposite ends of the connecting arm 56. The snap-fit ​​arms 54 pass through the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22. Each snap-fit ​​arm 54 is provided with a clamping part 58, which is embedded in the second snap-fit ​​groove 22. The two clamping parts 58 clamp the second connecting part 20.

[0058] This improves the stability of the connection between the snap-fit ​​connector 12 and the water pump 28 and the pipeline.

[0059] Specifically, the clamping part 58 is embedded in the second slot 22, and the two clamping parts 58 clamp the second connecting part 20, so that after the second connecting part 20 is inserted into the insertion space 16 of the first connecting part 14, the clamping parts 58 clamp and fix the second connecting part 20 at the second slot 22, making the second connecting part 20 less likely to wobble. At the same time, since the clamping arm 54 passes through the first slot 18 and the clamping part 58 is embedded in the second slot 22, the second connecting part 20 cannot be pulled out from the insertion space 16, which can improve the stability of the connection between the clamping member 12 and the water pump 28 and the pipeline.

[0060] exist Figure 4 In the embodiment shown, the snap-fit ​​12 is in the form of a snap pin, and the connecting arm 56 can function as an operating part, making it convenient for the user to operate the snap-fit ​​12 for assembly and disassembly.

[0061] exist Figure 5 In the embodiment shown, the snap-fit ​​connector 12 is in the form of a card. The snap-fit ​​connector 12 also includes a handle 59, which is connected to the side of the connecting arm 56 away from the clamping part 58. The handle 59 allows the user to easily operate the snap-fit ​​connector 12 for assembly and disassembly.

[0062] In some embodiments, the shape of the clamping part 58 is adapted to the shape of the periphery of the second connecting part 20 where the second slot 22 is provided.

[0063] Therefore, the clamping part 58 can better clamp the second connecting part 20.

[0064] Specifically, in one implementation, please refer to... Figure 1 , Figure 2 and Figure 4 The second connecting part 20 has a cylindrical periphery of the second slot 22, and the clamping part 58 is an arc shape that matches the cylindrical shape. This allows the clamping part 58 to fit better with the second connecting part 20. The clamping part 58 has a large contact area with the second connecting part 20, which reduces or avoids the shaking of the second connecting part 20 and makes the clamping of the second connecting part 20 more stable.

[0065] It is understood that in other embodiments, the periphery of the second slot 22 provided by the second connecting part 20 may be in other shapes, such as square column, polygonal column, etc., and is not limited to cylindrical.

[0066] In some implementations, please refer to Figure 1 and Figure 2 The water pump 28 has a first connector 46 and a second connector 48. One of the first connecting part 14 and the second connecting part 20 is provided at the first connector 46 and the second connector 48. The pipeline includes a first pipeline 50 and a second pipeline 52. The other of the first connecting part 14 and the second connecting part 20 is provided at one end of the first pipeline 50 and one end of the second pipeline 52.

[0067] Therefore, the water pump 28 and the pipeline can be fixedly connected by the engagement of the snap-fit ​​12 with the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22.

[0068] Specifically, in the illustrated embodiment, the first connecting part 14 is provided at the first connector 46 and the second connector 48, and the second connecting part 20 is provided at one end of the first pipe 50 and one end of the second pipe 52. It can be understood that in other embodiments, the second connecting part 20 is provided at the first connector 46 and the second connector 48, and the first connecting part 14 is provided at one end of the first pipe 50 and one end of the second pipe 52.

[0069] Pump 28 can provide power to the fluid (such as water) in the pipe, causing the fluid to flow faster. Figure 2 In this configuration, the first connector 46 is the outlet connector of the water pump 28, and the second connector 48 is the inlet connector of the water pump 28. The first pipe 50 is the outlet pipe of the water pump 28, which can be connected to the indoor unit. The second pipe 52 is the inlet pipe of the water pump 28. One end of the second pipe 52 is connected to the second connector 48 of the water pump 28, and the other end can be connected to the heat exchanger 26. The water flowing out of the heat exchanger 26 can enter the water pump 28 through the second pipe 52.

[0070] The first connector 46 and the second connector 48 are provided with a first connecting part 14, and the first connecting part 14 is provided with an insertion space 16. The second connecting part 20 of the first pipe 50 is inserted into the insertion space 16 of the first connector 46. A snap-fit ​​piece 12 passes through the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22 to fix the first connector 46 to the first pipe 50. The second connecting part 20 of the second pipe 52 is inserted into the insertion space 16 of the second connector 48. Another snap-fit ​​piece 12 passes through the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22 to fix the second connector 48 to the second pipe 52, thereby snapping the water pump 28 with the two pipes. During maintenance, this facilitates the disassembly and assembly of the water pump 28 and the pipes, reducing after-sales service time.

[0071] In some implementations, please refer to Figure 1 and Figure 3The hydraulic module 100 includes a heat exchanger 26, which has a third connector 60 and a fourth connector 62. One of the first connecting part 14 and the second connecting part 20 is disposed at the third connector 60 and the fourth connector 62. The pipeline includes a third pipeline 64. The other of the first connecting part 14 and the second connecting part 20 is disposed at one end of the third pipeline 64 and the other end of the second pipeline 62. The first connecting part 14 or the second connecting part 20 on the other end of the second pipeline 64 is fixedly connected to the second connecting part 20 or the first connecting part 14 of the fourth connector 62 through a snap-fit ​​member 12 passing through a first snap-fit ​​groove 18 and a second snap-fit ​​groove 22. The first connecting part 14 or the second connecting part 20 on one end of the third pipeline 64 is fixedly connected to the second connecting part 20 or the first connecting part 14 of the third connector 60 through a snap-fit ​​member 12 passing through a first snap-fit ​​groove 18 and a second snap-fit ​​groove 22.

[0072] Therefore, the heat exchanger 26 and the pipe can be fixedly connected by the engagement of the snap fastener 12 with the first snap slot 18 and the second snap slot 22.

[0073] Specifically, in the illustrated embodiment, the second connecting portion 20 is disposed on the third connector 60 and the fourth connector 62, and the first connecting portion 14 is disposed on one end of the third pipe 64 and the other end of the second pipe 52. The first connecting portion 14 on the other end of the second pipe 64 and the second connecting portion 20 of the fourth connector 62 are fixedly connected by a snap-fit ​​member 12 passing through a first snap-fit ​​groove 18 and a second snap-fit ​​groove 22. The first connecting portion 14 on one end of the third pipe 64 and the second connecting portion 20 of the third connector 60 are fixedly connected by a snap-fit ​​member 12 passing through a first snap-fit ​​groove 18 and a second snap-fit ​​groove 22. It can be understood that in other embodiments, the first connecting portion 14 is disposed on the third connector 60 and the fourth connector 62, and the second connecting portion 20 is disposed on one end of the third pipe 64 and the other end of the second pipe 52.

[0074] In one implementation, please refer to Figure 3 The accessory includes a second accessory 36, which has a first connecting part 14 and a third connecting part 38. The first connecting part 14 has an insertion space 16, and the third connecting part 38 has an assembly space 40. One end of the connecting pipe is inserted into the assembly space 40, so that the body 34 and the second accessory 36 are connected to form a second pipe 52. The second connecting part 20 can be inserted into the insertion space 16 of the second accessory 36, so that the first slot 18 of the first connecting part 14 and the second slot 22 of the second connecting part 20 are aligned and connected. Then, the snap-fit ​​member 12 is inserted into the first slot 18 and the second slot 22, thereby fixing the first connecting part 14 and the second connecting part 20 together.

[0075] Heat exchanger 26 can exchange heat between the fluid (such as water) flowing into the pipe and the refrigerant, thereby heating or cooling the fluid within the pipe. Figure 3In this configuration, the third connector 60 is the inlet connector of the heat exchanger 26, and the fourth connector 62 is the outlet connector of the heat exchanger 26. The third pipe 64 is the inlet pipe of the heat exchanger 26, with one end connected to the indoor unit and the other end connected to the third connector 60. The second pipe 52 is the outlet pipe of the heat exchanger 26, with one end connected to the fourth connector 62 of the heat exchanger 26 and the other end connected to the water pump 28. The fluid flowing out of the heat exchanger 26 can enter the water pump 28 through the second pipe 52.

[0076] The second pipe 62 connects the fourth connector 62 (outlet connector) of the heat exchanger 26 to the second connector 48 (inlet connector) of the water pump 28.

[0077] Both the third pipe 64 and the second pipe 66 have insertion spaces 16 at one end and the second connector 60 at the other end. The second connecting part 20 of the third connector 60 is inserted into the insertion space 16 of the third pipe 64. A snap-fit ​​piece 12 passes through the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22 to fix the third connector 60 to the third pipe 64. The second connecting part 20 of the fourth connector 62 is inserted into the insertion space 16 of the second pipe 52. Another snap-fit ​​piece 12 passes through the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22 to fix the fourth connector 62 to the second pipe 52. This allows the heat exchanger 26 to be snapped into the two pipes, facilitating the disassembly and assembly of the heat exchanger 26 and the pipes during maintenance and reducing after-sales service time.

[0078] The hydraulic module 100 may include a housing 68, and the other end of the third pipe 64 may pass through the housing 68.

[0079] In some implementations, please refer to Figure 6 The hydraulic module 100 includes a water tank 70, which has a hot water connector 72, and a second pipe 52 connecting the water pump 28 and the hot water connector 72.

[0080] Therefore, when the water pump 28 is connected to the water tank 70, the water pump 28 can be quickly disassembled and assembled.

[0081] Specifically, in one embodiment, the number of hot water connectors 72 is single, and hot water can flow in and out of the hot water connectors 72 of the water tank 70. The hydraulic module 100 may include three water pumps 28, namely, an upper water pump 28, a middle water pump 28, and a lower water pump 28 from top to bottom. The lower water pump 28 is connected to a fifth connector 74 through a first pipe 50. The fifth connector 74 can be connected to an outdoor unit, which can generate hot water using a heat pump system. The outdoor unit delivers the hot water from the fifth connector 74, the first pipe 50, the lower water pump 28, and the second pipe 52 to the hot water connector 72 and into the water tank 70 for storage.

[0082] The greywater pump 28 is connected to a sixth connector 76 via the first pipe 50. The sixth connector 76 can be connected to a zone system, which includes, but is not limited to, fan coil units. Hot water stored in the water tank 70 can be transported to the fan coil units via the hot water connector 72, the second pipe 52, the greywater pump 58, the first pipe 50, and the sixth connector 76. The fan coil units can dissipate the heat from the hot water into the room, raising the indoor temperature.

[0083] The water pump 28 is connected to a seventh connector 78 via the first pipe 50. The seventh connector 78 can be connected to a zone two system, which may include, but is not limited to, underfloor heating and / or radiators. Hot water stored in the water tank 70 can be transported to the underfloor heating and / or radiators via the hot water connector 72, the second pipe 52, the water pump 58, the first pipe 50, and the seventh connector 78. Underfloor heating can radiate heat from the hot water to the floor, and radiators can radiate heat from the hot water into the room, thereby raising the temperature of the floor and / or the room. When the water pump 28 is running, it can accelerate the flow of hot water, thereby improving heating efficiency.

[0084] The chilled water generated after heat exchange in Zone 1 and Zone 2 systems can be returned to the water tank 70 via pipes. The chilled water supplied to the outdoor unit can be output from the water tank 70 via pipes.

[0085] Optionally, the water tank 70 can be connected to the second pipe 52 via a valve such as a three-way valve to control the input and output of water. The water tank 70 includes, but is not limited to, a buffer tank. It is understood that in other embodiments, the number of hot water connectors 72 may be two or more.

[0086] The heating unit provided by this utility model includes the hydraulic module 100 of any of the above embodiments.

[0087] In the aforementioned heating unit, the snap-fit ​​connector 12 is detachably inserted through the first snap-fit ​​groove 18 and the second snap-fit ​​groove 22 so that the water pump 28 and the pipe are fixedly connected through the first connecting part 14 and the second connecting part 20. Thus, the water pump 28 and the pipe can be disassembled and assembled by detaching and assembling the snap-fit ​​connector 12, which can reduce the operating space to a certain extent and reduce the difficulty of replacing parts after sales.

[0088] Specifically, in one implementation, please refer to... Figure 6 The heating unit may include an outdoor unit, a domestic water tank, a gas boiler, a zone one system, and a zone two system. The hydraulic module 100 can be connected to the outdoor unit, the domestic water tank, the gas boiler, the zone one system, and the zone two system via pipes. The outdoor unit may include a heat pump system, which can use the heat pump system to heat cold water into hot water and then supply the hot water to the hydraulic module 100 via the fifth connector 74.

[0089] The gas boiler can use the heat generated during gas combustion to heat cold water to form hot water. The hot water output from the gas boiler can be input into the hydraulic module 100 via the fifth connector 74.

[0090] Optionally, the heating unit also includes a solar panel, which can be connected to the hydraulic module 100 via a fifth connector 74. The solar panel is used to convert solar energy into heat energy to heat water, and the resulting hot water can be transmitted to the hydraulic module 100 via the fifth connector 74.

[0091] Firstly, the hydraulic module 100 can deliver hot water to the coil inside the domestic water tank. The hot water then transfers heat through the coil to the domestic water in the tank, raising its temperature. The domestic water tank can be connected to faucets, showerheads, and other water outlet valves, allowing the heated domestic water to be supplied to users.

[0092] Secondly, the hydraulic module 100 can deliver hot water to a zone one system via a sixth connector 76. The zone one system may include heaters suspended from the indoor ceiling, including but not limited to fan coil units (FCUs). The fan coil units can dissipate the heat from the hot water into the room, raising the indoor temperature.

[0093] Thirdly, the hydraulic module 100 can deliver hot water to the zone two system via the seventh connector 78. The zone two system may include underfloor heating and / or radiators. Underfloor heating can radiate the heat of the hot water to the floor, and radiators can radiate the heat of the hot water into the room, thereby raising the temperature of the floor and the room.

[0094] It is understandable that heating units are not limited to the above-mentioned structures and components.
