[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Taking split-type air conditioners as an example, a split-type air conditioner consists of an indoor unit and an outdoor unit. During installation, the indoor and outdoor units are typically packaged and delivered separately to a designated location, where professionals connect the piping between the indoor and outdoor units on-site. After installation, the air conditioner needs to be vacuumed to remove internal air and ensure its cooling and heating performance. In related technologies, multiple connectors are required to achieve vacuuming during installation. For example, the connectors connecting to the air conditioner, the vacuum gauge, and the pressure switch are different. Therefore, multiple connectors need to be connected before vacuuming, which can lead to missed connectors, low assembly efficiency, and inconvenience in carrying the unit. Furthermore, leaks may occur due to loose connections between connectors. Additionally, the work is inconvenient for professionals operating in confined spaces at heights.

[0026] To address the aforementioned problems, this application provides an air conditioner, please refer to [link to relevant documentation]. Figures 1 to 2 The air conditioner includes an outdoor unit 400 and a connector 100 according to any embodiment of the present application. The connector 100 is used to connect to a valve body and a vacuum pump 300 to evacuate the outdoor unit 400 by means of the vacuum pump 300.

[0027] It is understandable that air conditioners can come in various forms. An air conditioner can be the indoor unit of a split air conditioner, an outdoor unit of a split air conditioner, or an integrated air conditioner, etc. There are no specific restrictions on the types of air conditioners that can be used for the packaging components.

[0028] Please see Figures 1 to 2 In another aspect, this application provides a connector 100, which includes a connecting body 10. The connecting body 10 includes a connecting channel and a first interface 111, a second interface 131, and a third interface 121, all of which are connected to the connecting channel. The first interface 111 is used to connect to the valve body of an air conditioner, the second interface 131 is used to connect to a vacuum gauge 200 or a pressure holding switch 20, and the third interface 121 is used to connect to a vacuum pump 300. The connecting body 10 is a one-piece molded structure.

[0029] The second interface 131 is used to connect to the vacuum gauge 200 or the pressure holding switch 20. That is, the connection body 10 integrates at least the second interface 131 for connecting to the vacuum gauge 200 or the pressure holding switch 20.

[0030] For example, the vacuum gauge 200 can be a smart vacuum gauge 200 that can directly read the vacuum value. By setting the vacuum gauge 200, the vacuum value within the connection channel can be detected, which helps to improve the convenience and accuracy of vacuuming.

[0031] By setting the pressure holding switch 20, after the vacuum is evacuated, the pressure holding switch 20 can be turned off, the pressure can be maintained for a certain period of time, and then the vacuum value in the connection channel can be detected by the vacuum gauge 200 to confirm whether the vacuum value is within a stable range.

[0032] When the pressure holding switch 20 is in the closed state, it can block the connection between the vacuum pump 300 and the connection channel. When the pressure holding switch 20 is in the open state, it connects the vacuum pump 300 and the connection channel.

[0033] Please see Figure 2 The connecting body 10 is equipped with a first interface 111, a second interface 131 and a third interface 121 that are all connected to the connecting channel. That is, the connecting body 10 is equipped with multiple interfaces to connect with multiple components, thereby reducing the number of components used.

[0034] There are no restrictions on the molding method of the connecting body 10.

[0035] For example, the connecting body 10 can be formed and then processed by die casting or forging.

[0036] There are no restrictions on the material of the connecting body 10.

[0037] For example, the connecting body 10 can be made of materials such as copper, aluminum, or steel.

[0038] This application provides a connector 100 and an air conditioner. By setting the connecting body 10 of the connector 100 as an integrally formed structure, the connecting body 10 is provided with a first interface 111, a second interface 131 and a third interface 121. The first interface 111 is used to connect to the valve body of the air conditioner, the second interface 131 is used to connect to the vacuum gauge 200 or the pressure holding switch 20, and the third interface 121 is used to connect to the vacuum pump 300. That is to say, the connector 100 integrates at least the second interface 131 connected to the vacuum gauge 200 or the pressure holding switch 20. This helps to reduce the use of connecting parts and improve the leakage caused by the lack of locking between multiple connecting parts. Therefore, the connector 100 of this application is beneficial to reduce the risk of leakage during the vacuuming process while being easy to carry and improving assembly efficiency.

[0039] In some embodiments, please refer to Figure 2 The connecting body 10 also includes a fourth interface 141 that communicates with the connecting channel. The second interface 131 and the fourth interface 141 are used to connect to the vacuum gauge 200 and the pressure holding switch 20, respectively.

[0040] In other words, the second interface 131 is used to connect to the vacuum gauge 200, and the fourth interface 141 is used to connect to the pressure holding switch 20. That is, the connector 100 integrates at least the second interface 131 connected to the vacuum gauge 200 and the fourth interface 141 connected to the pressure holding switch 20.

[0041] This further reduces the number of connectors, thereby further improving the leakage problem caused by the lack of locking between multiple connectors, and further facilitating portability and improving assembly efficiency.

[0042] In some embodiments, please refer to Figure 2 The connecting body 10 also includes a fifth interface 112 communicating with the connecting channel, and the connector 100 also includes a valve core switch 50, which is disposed in the fifth interface 112 and is used to selectively open or close the valve body of the air conditioner.

[0043] In other words, connector 100 integrates at least a fifth interface 112 for connection with valve core switch 50.

[0044] By setting the valve core switch 50 at the fifth interface 112 of the connecting body 10 and connecting the first interface 111 of the connector 100 to the valve body of the air conditioner, the valve body of the air conditioner can be selectively opened or closed by the valve core switch 50. For example, opening the valve core switch 50 connects the air conditioner to the connecting channel, and then vacuuming is performed using the vacuum pump 300. After vacuuming, the pressure holding switch 20 is closed, pressure is maintained for a certain period, and the vacuum value is kept within a stable range. Then, the valve core switch 50 is closed to disconnect the air conditioner from the connecting channel, i.e., the two are no longer connected. At this point, the first interface 111 can be detached from the valve body of the air conditioner. Then, the air conditioner is started for testing, and the operation is complete.

[0045] This further reduces the number of connectors, thereby further improving the leakage problem caused by the lack of locking between multiple connectors, and further facilitating portability and improving assembly efficiency.

[0046] In some embodiments, the operating portions of the valve core switch 50 and the pressure holding switch 20 are exposed outside the connecting body 10, and the operating portions of the valve core switch 50 and the pressure holding switch 20 are of different colors.

[0047] For example, the operating part of the valve core switch 50 may be a nut exposed on the connecting body 10, and the valve body of the air conditioner can be opened or closed by operating the nut of the valve core switch 50.

[0048] For example, the operating part of the pressure holding switch 20 may be a nut exposed on the connecting body 10, and the connection or disconnection between the vacuum pump 300 and the connecting channel can be achieved by operating the nut of the pressure holding switch 20.

[0049] By setting the colors of the operating parts of the valve core switch 50 and the pressure holding switch 20 to be different, it is easier for the operator to distinguish between the valve core switch 50 and the pressure holding switch 20.

[0050] Of course, in other embodiments, the operating part of the valve core switch 50 and the operating part of the pressure holding switch 20 can be distinguished by markings to differentiate the valve core switch 50 and the pressure holding switch 20.

[0051] The specific connection method between the first interface 111 and the valve body of the air conditioner is not limited here.

[0052] In some embodiments, please refer to Figure 2 The connector 100 includes a first connecting nut 30, which is disposed on the first interface 111 and is used to connect the first interface 111 to the valve body of the air conditioner.

[0053] By setting the first connecting nut 30 to connect the first interface 111 to the valve body of the air conditioner, the convenience and reliability of the connection between the connector 100 and the valve body are improved.

[0054] In other embodiments, the first interface 111 can be directly connected to the valve body, for example, by a threaded connection.

[0055] In some embodiments, please refer to Figure 2 The connector 100 includes a second connecting nut 40, which is disposed on the second interface 131 for connecting the second interface 131 and the vacuum gauge 200.

[0056] By setting a second connecting nut 40 to connect the second interface 131 and the vacuum gauge 200, the convenience and reliability of the connection between the second interface 131 and the vacuum gauge 200 are improved.

[0057] In other embodiments, the second interface 131 can be directly connected to the vacuum gauge 200, for example, by a threaded connection.

[0058] In some embodiments, connector 100 includes a sealing ring sandwiched between valve core switch 50 and fifth interface 112.

[0059] For example, the valve core switch 50 has a built-in sealing ring. After the valve core switch 50 is assembled to the fifth interface 112 of the connecting body 10, the sealing ring is sandwiched between the valve core switch 50 and the fifth interface 112.

[0060] By setting a sealing ring and clamping it between the valve core switch 50 and the fifth interface 112, the gap between the valve core switch 50 and the fifth interface 112 is sealed, thus improving the problem of connection leakage.

[0061] In some embodiments, the sealing ring is sandwiched between the first connecting nut 30 and the valve body. For example, the first connecting nut 30 has a built-in sealing ring. After the first connecting nut 30 is assembled to the valve body, the sealing ring is sandwiched between the first connecting nut 30 and the valve body.

[0062] By setting a sealing ring and clamping it between the first connecting nut 30 and the valve body, the gap between the first connecting nut 30 and the valve body is sealed, thus improving the problem of connection leakage.

[0063] In some embodiments, the sealing ring is sandwiched between the second connecting nut 40 and the vacuum gauge 200.

[0064] For example, the second connecting nut 40 has a built-in sealing ring. After the vacuum gauge 200 is assembled to the second connecting nut 40, the sealing ring is sandwiched between the second connecting nut 40 and the vacuum gauge 200.

[0065] By setting a sealing ring and clamping it between the second connecting nut 40 and the vacuum gauge 200, the gap between the second connecting nut 40 and the vacuum gauge 200 is sealed, thus improving the problem of connection leakage.

[0066] In some embodiments, please refer to Figure 1 and Figure 2 The first connecting nut 30 is connected to the valve body along the first direction, and the first connecting nut 30 is rotatably connected to the first interface 111. During the rotation of the first connecting nut 30 relative to the first interface 111, the position of the first connecting nut 30 in the first direction remains unchanged.

[0067] In other words, the first connecting nut 30 is rotatably connected to the first interface 111, and during the relative rotation of the first connecting nut 30 and the first interface 111, the first connecting nut 30 and the first interface 111 do not produce relative displacement in the first direction.

[0068] For example, the first connecting nut 30 is provided with an internal thread, and the valve body is provided with an external thread, so that the first connecting nut 30 is threadedly connected to the valve body.

[0069] During the rotation of the first connecting nut 30 relative to the first interface 111, the position of the first connecting nut 30 in the first direction remains unchanged. Thus, by rotating the first connecting nut 30 to lock it, the first connecting nut 30 drives the connecting body 10 to move closer to the valve body in the first direction, thereby achieving the locking between the connector 100 and the valve body. During the locking process, it is not necessary to rotate the connecting body 10 and the valve body, which helps to reduce the operating space, facilitates the adjustment of the angle and position of the connecting body 10 relative to the air conditioner, and further facilitates operations such as reading values ​​from the vacuum gauge 200.

[0070] In some embodiments, please refer to Figure 2 The second connecting nut 40 is aligned with the vacuum gauge 200 along the second direction. The second connecting nut 40 is rotatably connected to the second interface 131. During the rotation of the second connecting nut 40 relative to the second interface 131, the position of the second connecting nut 40 in the second direction remains unchanged.

[0071] For example, the first direction and the second direction can be parallel or intersecting, such as perpendicular.

[0072] In other words, the second connecting nut 40 is rotatably connected to the second interface 131, and during the relative rotation of the second connecting nut 40 and the second interface 131, the second connecting nut 40 and the second interface 131 do not produce relative displacement in the second direction.

[0073] For example, the second connecting nut 40 is provided with internal threads, and the vacuum gauge 200 is provided with external threads, so that the second connecting nut 40 is threadedly connected to the vacuum gauge 200.

[0074] During the rotation of the second connecting nut 40 relative to the second interface 131, the position of the second connecting nut 40 in the second direction remains unchanged. Thus, by rotating the second connecting nut 40 to lock it, the second connecting nut 40 drives the connecting body 10 to move in the second direction toward the vacuum gauge 200, thereby achieving the locking between the connector 100 and the vacuum gauge 200. During the locking process, it is not necessary to rotate the connecting body 10 and the vacuum gauge 200, which helps to reduce the operating space, facilitates the adjustment of the angle and position of the vacuum gauge 200 relative to the connecting body 10, and further facilitates operations such as reading values ​​from the vacuum gauge 200.

[0075] The specific structure of connector 100 is not limited here.

[0076] In some embodiments, please refer to Figures 1 to 2The connecting body 10 includes a first conduit 11 and a second conduit 12 that are interconnected. The two ends of the first conduit 11 form a first interface 111 and a fifth interface 112, respectively, and the end of the second conduit 12 furthest from the first conduit 11 forms a third interface 121. The connecting body 10 also includes a first sub-pipe 13 and a second sub-pipe 14 that are both connected to the second conduit 12. The end of the first sub-pipe 13 furthest from the second conduit 12 forms a second interface 131, and the end of the second sub-pipe 14 furthest from the second conduit 12 forms a fourth interface 141. The second sub-pipe 14 is closer to the third interface 121 than the first sub-pipe 13.

[0077] In this way, the size of connector 100 and the installation space required for connector 100 can be reduced as much as possible, and the connection between the main body 10 and vacuum gauge 200, pressure holding switch 20 and valve core switch 50 can be facilitated.

[0078] This application provides a simple, quick, easy-to-connect, portable, and leak-proof integrated vacuum connector 100 to ensure that air conditioner installation meets standard requirements, maximizes energy efficiency, and reduces the risk of leakage. By making the connector body 10 a one-piece molded structure, it solves the problem of installers quickly connecting various functional components, while also reducing many unnecessary connectors and preventing the risk of leakage due to connections between components. The connector 100 integrates a valve core switch 50, seals, and functional connection devices, making it more convenient for installers to operate in confined spaces, and its operation is simple and practical.

[0079] The first pipe 11 and the second pipe 12 may intersect; for example, the first pipe 11 and the second pipe 12 may be perpendicular to each other.

[0080] The first pipe 11 has a first interface 111 and a fifth interface 112 at its two ends, respectively. The first interface 111 and the fifth interface 112 are arranged opposite to each other, so that the valve body of the air conditioner can be selectively opened or closed by the valve core switch 50.

[0081] The first sub-pipe 13 and the second pipe 12 may intersect; for example, the first sub-pipe 13 and the second pipe 12 may be perpendicular.

[0082] The second sub-pipe 14 and the second pipe 12 may intersect; for example, the second sub-pipe 14 and the second pipe 12 may be perpendicular.

[0083] The first sub-tube 13 and the second sub-tube 14 can be intersecting or parallel.

[0084] For example, the first sub-pipe 13 may also be parallel to the first conduit 11.

[0085] By placing the second sub-tube 14 closer to the third interface 121 relative to the first sub-tube 13, the vacuum gauge 200 can detect the vacuum value of the connection channel when the pressure holding switch 20 is closed.

[0086] In some embodiments, please refer to Figures 1 to 2 The centerline of the first pipe 11 and the centerline of the second pipe 12 define a first plane. The centerline of the first sub-pipe 13 is perpendicular to the centerline of the second pipe 12, and the angle between the sub-pipe 13 and the first plane ranges from 0° to 360°.

[0087] In other words, the angle between the first sub-tube 13 and the first plane can be arbitrary. This allows installers to read values ​​quickly from the front without having to bend down in confined spaces.

[0088] In some embodiments, please refer to Figure 1 The air conditioner also includes a connecting hose 500, and the third interface 121 is connected to the vacuum pump 300 through the connecting hose 500.

[0089] The vacuuming operation includes the following steps: After connecting the entire unit, open the valve core switch 50 to connect the air conditioner to the connection channel; start the vacuum pump 300 and run it for about 15 minutes, then read the value of the vacuum gauge 200 (the value that meets the standard); after vacuuming, close the pressure holding switch 20, maintain the pressure for a certain period of time, and ensure that the vacuum value is within a stable range, then close the valve core switch 50 to disconnect the air conditioner from the connection channel; disconnect the first interface 111 from the valve body of the air conditioner; then start the air conditioner for operation and testing, and the operation is complete.
