[0039] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0040] The present application provides a heat pump system, which can be a ground source heat pump, an air source heat pump, or an air-cooled heat pump, but is not limited thereto. For ease of explanation, the following heat pump systems are all traditional air source heat pumps.

[0041] The heat pump system of this embodiment includes an outdoor unit and a hydraulic module 100. The outdoor unit is used to exchange heat with the external environment, while the hydraulic module 100 is used to exchange heat between the refrigerant in the refrigerant pipe and the water in the water pipe, thereby heating or cooling the water, thereby outputting water at a set temperature and delivering it to a water storage device such as a water tank, or to a heat release device such as a floor heating pipe or radiator.

[0042] As mentioned in the background technology, multiple joints are generally welded on a pipeline, and then the multiple joints are connected to corresponding integrated water tanks, pressure gauges, safety valves, exhaust valves, expansion tanks and other water components, which has high welding costs.

[0043] To solve the above technical problems, please refer to Figure 1-2 An embodiment of the present application provides a hydraulic module, including an integrated pipeline 100, a safety valve 200, an exhaust valve 300, a sensor 400, a buffer water tank 500 and an expansion tank 600. The integrated pipeline 100 has multiple interfaces, the expansion tank 600 is connected to one of the interfaces through a connecting pipe, and the safety valve 200, the exhaust valve 300, the sensor 400 and the buffer water tank 500 are respectively connected to the remaining corresponding interfaces.

[0044] In this way, the safety valve 200, the exhaust valve 300, the sensor 400, the buffer water tank 500, and the expansion tank 600 are connected into a whole through an integrated pipeline 100 with multiple interfaces. There is no need to weld joints on the integrated pipeline 100, which reduces the number of pipeline connection points. This not only reduces costs, but also reduces system complexity and installation difficulty, thereby improving the integrity and reliability of the system.

[0045] Among them, the water inlet of the buffer water tank 500 is at the top and the water outlet is at the bottom. According to the different water temperatures of the inlet and outlet, temperature zoning can be achieved; according to the usage of the terminal heating end, the excess heat source can be stored in the buffer water tank 500, or the heat source of the buffer water tank 500 can be extracted to participate in the terminal temperature regulation; the terminal return water is to the bottom of the buffer water tank 500, and at the same time, the external unit return water is also taken from the buffer water tank 500 to achieve dynamic balance.

[0046] The safety valve 200 is used to prevent the internal pressure of the system from being too high. When the pressure exceeds the set value, the safety valve 200 will automatically open and release part of the pressure to protect the system equipment and pipelines from damage.

[0047] The exhaust valve 300 is used to remove air and other non-condensable gases in the system to prevent gas from accumulating in the system and forming air resistance or air lock, which affects the smooth circulation of water.

[0048] The expansion tank 600 is mainly used to balance the pressure, for example, to prevent the internal pressure of the buffer water tank 500 from being too high, which may damage the equipment.

[0049] The sensor 400 is used to detect the pressure, flow rate, or both of the pressure and flow rate of the water flowing through the integrated pipeline 100, thereby transmitting a signal to the controller, thereby instructing the controller to control the opening and closing of the exhaust valve 300 and the safety valve 200. Specifically, the sensor 400 can be a water pressure gauge for detecting water pressure, a flow meter for detecting water flow, or a sensor 400 that integrates a water pressure gauge and a flow meter. The use of a water pressure gauge to detect water pressure and a flow meter to detect water flow are both prior arts and are not further explained in the embodiments of this application.

[0050] Further, see Figure 2 The embodiment of the present application also includes multiple connector assemblies 700 and multiple connection assemblies 800, and the multiple connector assemblies 700 are connected to the multiple interfaces in a one-to-one correspondence, wherein each connector assembly 700 includes a first connector 710 and a second connector 720, and one of the first connector 710 and the second connector 720 is set at the corresponding interface, and the first connector 710 and the second connector 720 are detachably connected through the corresponding connection assembly 800.

[0051] That is, when there are 5 interfaces, the number of connector assemblies 700 and the number of connection assemblies 800 are also 5. When there are 6 interfaces, the number of connector assemblies 700 and the number of connection assemblies 800 are also 6. In the embodiment of the present application, there is no restriction on the number of interfaces, and the number can be increased or deleted according to actual conditions.

[0052] In a specific implementation, the first connector 710 may be set at the interface of the integrated pipeline 100, the second connector 720 may be set at the interface of the integrated pipeline 100, or the first connector 710 and the second connector 720 may be set at the interface of the integrated pipeline 100, and the corresponding first connector 710 or second connector 720 may be set on water path components such as the safety valve 200, the exhaust valve 300 and the sensor 400.

[0053] In the embodiment of the present application, since the water path components such as the integrated pipeline 100, the safety valve 200, the exhaust valve 300, the sensor 400, the buffer water tank 500 and the expansion tank 600 are all integrated in a box, the first connector 710 and the second connector 720 are detachably connected through the corresponding connecting assembly 800. In this way, the installation and disassembly of the integrated pipeline 100 and the safety valve 200, the exhaust valve 300, the sensor 400, the buffer water tank 500 and the expansion tank 600 and other water path components can be completed in a narrow area, ensuring the miniaturization design of the entire hydraulic module.

[0054] The two connectors are designed to match each other and can be tightly connected together to ensure smooth water flow and sealing. In the embodiment of the present application, the connector connected to the integrated pipeline 100 can be injection molded as one piece, or it can be cast from metal as one piece, that is, the integrated pipeline 100 can be injection molded as one piece with the first connector 710 and / or the second connector 720, or it can be cast from metal. In this way, the integrated pipeline 100 can form a seamless sealing structure with the corresponding first connector 710 and / or the second connector 720, which can effectively prevent liquid leakage and ensure the normal operation of the pipeline system.

[0055] Following the above, based on the fact that the first connector 710 can be set at the interface of the integrated pipeline 100, the second connector 720 can be set at the interface of the integrated pipeline 100, or the first connector 710 and the second connector 720 can be set at the interface of the integrated pipeline 100, the embodiment of the present application is described as an example in which the first connector 710 is set at the interface of the integrated pipeline 100.

[0056] See also Figure 3 When the first connector 710 is installed in the corresponding interface, the first connector 710 forms an installation cavity 710a, and the side wall of the first connector 710 is provided with a socket 710b connected to the installation cavity 710a. The second connector 720 is inserted into the installation cavity 710a, and the connecting component 800 is passed through the socket 710b. Among them, the outer side wall of the second connector 720 is provided with a first snap-fit ​​groove 720a, and the connecting component 800 is snap-fitted with the first snap-fit ​​groove 720a.

[0057] The first connector 710 can be set with both ends through, that is, the first connector 710 has an installation cavity 710a inside, the installation cavity 710a connects the opposite ends of the first connector 710 to each other, and one end of the first connector 710 is connected to the integrated pipeline 100, and the side wall of the first connector 710 is provided with a socket 710b connected to the installation cavity 710a.

[0058] The second joint 720 can also be set to be through-ended at both ends, that is, the second joint 720 has a channel inside, and the second channel connects the opposite ends of the second joint 720 to each other, and one end of the second joint 720 is connected to the safety valve 200 and other water channel components. The side wall of the second joint 720 can be provided with a first clamping groove 720a, and the outer diameter length of the second joint 720 is adapted to the inner diameter length of the first joint 710, so that the part of the second joint 720 inserted into the installation cavity 710a can fit with the side wall forming the installation cavity 710a to improve the sealing performance, and the first clamping groove 720a is arranged opposite to the socket 710b. In this way, after the first joint 710 and the second joint 720 are matched in place, the connecting component 800 can be passed through the socket 710b and clamped with the first clamping groove 720a.

[0059] The shape of the connecting component 800 can be adapted to the slots of the socket 710b and the first snap-fitting slot 720a, so that the connecting component 800 can be inserted into the socket 710b and the first snap-fitting slot 720a in sequence, and the connecting component 800 can be in a locked state with the socket 710b and the first snap-fitting slot 720a at the same time, thereby fixing the first connector 710 and the second connector 720.

[0060] When it is necessary to install the safety valve 200 and other related water channel components on the integrated pipeline 100, the second connector 720 can be inserted into the installation cavity 710a of the first connector 710, so that the first clamping groove 720a and the socket 710b are arranged opposite to and connected. At this time, it is only necessary to insert the connecting component 800 into the socket 710b and the first clamping groove 720a in turn, and the first connector 710 and the second connector 720 can be relatively fixed, thereby fixing the safety valve 200 and other related water channel components on the integrated pipeline 100. The staff does not need to use a lot of force, and the installation is very convenient. When it is necessary to repair or replace the safety valve 200 and other related water channel components, it is only necessary to pull the connecting component 800 out of the socket 710b and the first clamping groove 720a to release the fixation of the first connector 710 and the second connector 720, and the safety valve 200 and other related water channel components can be easily removed from the integrated pipeline 100.

[0061] For further information, please refer to Figure 3 The connecting component 800 includes a plug-in body 810 and two plug-in parts 820. The two plug-in parts 820 are connected to the plug-in body 810. The two plug-in parts 820 can be deformed relative to the plug-in body 810. The two plug-in parts 820 are inserted into the plug hole 710b and are located on opposite sides of the second connector 720.

[0062] Since the two plug-in parts 820 can be deformed relative to the plug-in body 810, when the plug-in part 820 is inserted into the plug hole 710b and clamped into the first clamping groove 720a, the two plug-in parts 820 can be relatively separated, so that there is enough space between the two plug-in parts 820 to allow them to be inserted into the plug hole 710b. After the plug-in part 820 is completed and inserted into the plug hole 710b and clamped into the first clamping groove 720a, the plug-in part 820 resumes its deformation, so that the second connector 720 can be clamped from the opposite sides of the second connector 720, thereby ensuring the stability of the connection between the first connector 710 and the second connector 720.

[0063] It should be understood that in order to further improve the stability of the connection between the first connector 710 and the second connector 720, the thickness of the plug-in portion 820 needs to be sufficient so that when the plug-in portion 820 is inserted into the socket 710b, the plug-in portion 820 fits against the opposite side walls of the socket 710b, thereby preventing the second connector 720 from moving relative to the first connector 710.

[0064] In the embodiment of the present application, the plug-in body 810 and the two plug-in parts 820 can be integrally formed or connected together by other connection methods. The setting of the plug-in body 810 can facilitate the user to pull out the connection component 800. Specifically, in the embodiment of the present application, the plug-in body 810 and the two plug-in parts 820 are an integral structure and are metal springs. The cost of metal springs is relatively low, and the metal springs can also have excellent deformation capabilities.

[0065] The cross-sectional shape of the first joint 710 and the second joint 720 can be rectangular or circular. In the embodiment of the present application, it is preferably circular, and correspondingly, the cross-sectional shape of the mounting cavity 710a is also circular, and correspondingly, the cross-sectional shape of the channel in the second joint 720 is also circular. In this way, the energy loss caused by the fluid hitting the edges during the flow process is reduced.

[0066] When the cross-sectional shape of the first connector 710 and the second connector 720 is circular, the entire first connector 710 and the second connector 720 are cylindrical. In this way, the first snap-fitting groove 720a is an arc-shaped groove, and the plug-in portion 820 also has an arc-shaped structure to enable the plug-in portion 820 to fit together with the first snap-fitting groove 720a. In this way, based on the elasticity of the plug-in portion 820, the user can pull it with one hand to complete the unlocking and locking of the first connector 710 and the second connector 720, so as to facilitate the relative fixation of the first connector 710 and the second connector 720 in a narrow position.

[0067] In the embodiment of the present application, the second connector 720 is inserted into the interior of the first connector 710. Therefore, in order to prevent the liquid from flowing out from between the second connector 720 and the first connector 710, refer to Figure 3The hydraulic module further includes a sealing member 900 , which is located between the inner wall of the installation cavity 710 a and the outer wall of the second joint 720 .

[0068] The sealing member 900 is sleeved on the outer peripheral side wall of the second joint 720. It can be fixed on the second joint 720, and can also be movably sleeved on the outer peripheral side wall of the second joint 720. The sealing member 900 adopts a sealing ring, and the sealing ring is made of rubber or silicone material and has elasticity. In this way, when the second joint 720 is inserted into the first joint 710, the second joint 720 can squeeze the sealing member 900 together with the second joint 720, thereby ensuring the sealing effect when the first joint 710 and the second joint 720 are connected.

[0069] Furthermore, along the depth direction of the installation cavity 710a, there may be only one seal 900, or there may be two or even more seals 900. It is understandable that the more seals 900 there are, the better the sealing effect between the first seal 900 and the second seal 900.

[0070] When the first connector 710 is connected to the interface of the integrated pipeline 100 and when the second connector 720 is connected to the first connector 710, the seal 900 is closer to the integrated pipeline 100 relative to the socket 710b along the depth direction of the installation cavity 710a. In this way, it is difficult for the liquid in the integrated pipeline 100 to flow to the outside through the socket 710b under the sealing effect of the seal 900.

[0071] When the second connector 720 is connected to the interface of the integrated pipeline 100, and when the second connector 720 is connected to the first connector 710, along the depth direction of the installation cavity 710a, the seal 900 is further away from the integrated pipeline 100 relative to the first clamping groove 720a. Similarly, it is difficult for the liquid in the integrated pipeline 100 to flow to the outside through the jack 710b under the sealing action of the seal 900.

[0072] It can be understood that by setting the second snap-fit ​​groove 720b, a position for installing the seal 900 can be formed, so that the seal 900 can be relatively fixed on the peripheral side surface of the second joint 720, and the second snap-fit ​​groove 720b can also play a limiting role on the seal 900. During the process of inserting the second joint 720 into the first joint 710, the seal 900 can be prevented from moving along the axial direction of the second joint 720.

[0073] When the sealing member 900 is movably sleeved in the second engaging groove 720 b , when the sealing effect of the sealing member 900 is weakened, it is convenient for the user to quickly replace the sealing member 900 with a new one to ensure the sealing effect.

[0074] Optionally, the groove depth of the second snap-fit ​​groove 720b is smaller than the thickness of the seal 900. When the seal 900 is arranged in the second snap-fit ​​groove 720b, the seal 900 at least partially extends from the second snap-fit ​​groove 720b, so that the sealing ring can be squeezed between the first joint 710 and the second joint 720, thereby increasing the sealing between the first joint 710 and the second joint 720.

[0075] Furthermore, in order to enable the first connector 710 and the second connector 720 to be quickly connected together, in the implementation of the present application, the first connector 710 is provided with a bottom wall on the side of the installation cavity 710a facing the integrated pipeline 100. When the connecting assembly 800 connects the first connector 710 and the second connector 720, the second connector 720 abuts against the bottom wall.

[0076] The design of the bottom wall allows the installer to more easily determine the relative positions of the first connector 710 and the second connector 720, and enables the socket 710b to be opposite to the first snap-in groove 720a, so that the connecting component 800 can be accurately snapped into the first snap-in groove 720a after being passed through the socket 710b, thereby simplifying the installation process. At the same time, since the bottom wall provides stable support, the installer can focus more on the tightening operation of the connecting component 800, thereby improving installation efficiency.

[0077] On the other hand, the existence of the bottom wall provides a stable support surface for the second joint 720, so that during the connection process, the second joint 720 can be accurately positioned and docked with the first joint 710. This stable support reduces the problem of loose connection caused by joint misalignment or shaking, thereby enhancing the stability of the connection.

[0078] In addition, when the first joint 710 and the second joint 720 are installed along the direction of gravity, the presence of the bottom wall can ensure the relative fixation of the first joint 710 and the second joint 720, so that the user can focus more on the tightening operation of the connection component 800, thereby improving installation efficiency.

[0079] See also Figure 3-4 The hydraulic module also includes a limiting tooth 721, which is provided on the side wall of the second joint 720. The side wall of the first joint 710 is provided with a limiting groove 710c. When the second joint 720 is inserted into the installation cavity 710a, the limiting tooth 721 is engaged with the limiting groove 710c.

[0080] Optionally, the limiting tooth 721 can protrude outward from the peripheral side of the second joint 720, and the end face of the first joint 710 can be provided with a limiting groove 710c adapted to the limiting tooth 721. Before the second joint 720 is inserted into the first joint 710, the limiting tooth 721 can be aligned with the limiting groove 710c, so that when the second joint 720 is inserted into the first joint 710, the limiting tooth 721 can be synchronously inserted into the limiting groove 710c. The limiting tooth 721 is plugged into the limiting groove 710c, which can limit the relative rotation between the first joint 710 and the second joint 720, so that the second joint 720 and the first joint 710 can be fixed more stably.

[0081] In some other embodiments, when the second connector 720 is plugged into the first connector 710, the axis of the second connector 720 can be set colinearly with the axis of the first connector 710, and as the second connector 720 is gradually inserted into the interior of the first connector 710, the limiting tooth 721 can contact the bottom surface of the limiting groove 710c. At this time, the limiting groove 710c can also limit the second connector 720 from continuing to be inserted into the first connector along its own axial direction. It can also be said that after the second connector 720 is inserted into the first connector 710 to a preset depth, the second connector 720 cannot continue to extend into the first connector 710, and the first clamping groove 720a and the socket 710b are just oppositely arranged.

[0082] Therefore, through the plug-in cooperation between the limiting tooth 721 and the limiting groove 710c, the second connector 720 can be quickly inserted into the preset position in the first connector 710, so that the first clamping groove 720a and the socket 710b are just oppositely arranged and connected, which can increase the assembly speed and accuracy of the second connector 720 and the first connector 710.

[0083] In order to improve the stability of the entire hydraulic module, the outer wall of at least one of the integrated pipeline 100, the first joint 710 and the second joint 720 is provided with a reinforcing rib 1000. Specifically, the integrated pipeline 100, the first joint 710 and the second joint 720 may all be provided with a reinforcing rib 1000, or only one or two of the integrated pipeline 100, the first joint 710 and the second joint 720 may have a reinforcing rib 1000.

[0084] It is understood that when the integrated pipeline 100 and the first connector 710 are injection molded, i.e., integrally injection molded, the provision of the reinforcing ribs 1000 can greatly improve the structural strength and rigidity of the entire integrated pipeline 100 and the first connector 710. Of course, when the integrated pipeline 100 and the second connector 720 are injection molded, the reinforcing ribs 1000 can also improve the structural strength and rigidity of the second structure.

[0085] The same or similar numbers in the drawings of this embodiment correspond to the same or similar items; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship, they are based on the orientation or position relationship described in the drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
