Description

Technical Field

[0001] This application relates to the field of pipeline connection technology, and in particular to a pipeline connection protection component, equipment housing, leak detection system and air conditioning equipment. Background Technology

[0002] During equipment operation, the target fluid needs to be transported through pipelines. Since the connection area between internal and external pipelines is usually outside the equipment housing, it is impossible to effectively protect the connection area, which can easily lead to leakage of the target fluid in the pipeline at the connection area.

[0003] For example, existing air conditioning equipment, such as residential units, usually requires the transportation of refrigerant through piping assemblies. The connection between the indoor and outdoor unit piping is located outside the residential unit casing. On the one hand, this is not conducive to protecting the piping connection area; on the other hand, since the refrigerant leak detection sensor is located inside the residential unit casing, once a leak occurs at the interface of the indoor and outdoor unit connecting pipes, the refrigerant leak detection sensor inside the residential unit casing will not be able to detect the leak.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0059] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0060] To address the technical problem in the prior art that pipeline components 5 are prone to leakage due to the inability to effectively protect the connection area between two pipeline sections, and that such leakage is difficult to detect, this application provides a pipeline connection protection component, an equipment housing, a leakage detection system, and an air conditioning device. This pipeline connection protection component can protect the connection area of ​​the pipeline through the pipeline housing 2, protecting the weak areas of the pipeline component 5 and preventing loosening and leakage caused by external influences. Furthermore, through the connection of the housing connector 1, the pipeline housing 2, and the sealing component 3, the accommodating cavity 21 communicates with the internal cavity 41 of the housing body 4 within the equipment housing via the opening 11, allowing the detection sensor 6 installed in the internal cavity 41 of the housing body 4 to monitor leakage in the connection area.

[0061] Please see Figures 1 to 21 The first aspect of this application provides a pipeline connection protection assembly, including a housing connector 1, a pipeline accommodating member 2, and a sealing member 3, such as... Figure 1 , Figure 5 and Figure 12 As shown. The housing connector 1 has an opening 11 in the middle, which communicates with the internal cavity 41 of the housing body 4, allowing the internal pipe 51 located in the internal cavity 41 to extend from the internal cavity 41 and the opening 11, and connect to the external pipe 52 outside the housing body 4. Figure 16 and Figure 21 As shown.

[0062] The pipe housing 2 has a accommodating cavity 21 for accommodating the pipe, which protects the connection area of ​​the pipe and the vulnerable areas of the pipe assembly 5, preventing loosening and leakage due to external influences. The accommodating cavity 21 communicates with the opening 11, thereby connecting the accommodating cavity 21 to the internal cavity 41 of the housing body 4. This allows the detection sensor 6, located within the internal cavity 41, to monitor for leaks in the pipe connection area, eliminating the need for additional leak detection devices at the pipe connection points.

[0063] The sealing member 3 is sealed to the pipeline receiving member 2 to seal one side of the receiving cavity 21, so that the receiving cavity 21 can only communicate with the internal cavity 41 through the opening 11. The sealing member 3 is provided with a through hole 31 for inserting a pipeline, so that the external pipeline 52 located outside the housing body 4 can extend into or out. The wall of the through hole 31 is provided with a first sealing member 32 to achieve a seal between the wall of the through hole 31 and the wall of the external pipeline 52, so as to avoid the existence of gaps between them, which would affect the monitoring results of the detection sensor 6.

[0064] It should be noted that the accommodating cavity 21 formed by the pipeline accommodating member 2 in this application can wrap and protect the connection area of ​​the pipeline assembly 5, reducing the possibility of leakage in the connection area of ​​the pipeline assembly 5 due to external factors; and through the connection of the shell connector 1, the pipeline accommodating member 2 and the sealing member 3, the accommodating cavity 21 is connected to the internal cavity 41 of the shell body 4 only through the opening 11, so that the existing detection sensor 6 in the internal cavity 41 can be used to synchronously monitor whether there is leakage inside the accommodating cavity 21, which can improve the reliability of the pipeline connection.

[0065] In some embodiments of this application, please refer to Figure 2 , Figure 13 , Figure 14 , Figure 15 , Figure 20 and Figure 21 A first connecting part 13 is provided along the circumference of the housing connector 1. The first connecting part 13 is used for detachable connection with the housing body 4, so as to realize the separate manufacturing of the pipeline connection protection component and the housing body 4. In the process of production and use, it is also convenient to realize the pre-installation, disassembly or replacement of the pipeline connection protection component.

[0066] It should be noted that the detachable connection between the first connecting part 13 and the housing body 4 can be achieved by means of screw connection or snap connection, as long as it facilitates the pre-installation, disassembly or replacement of the pipeline connection protection component, the purpose of this application can be achieved.

[0067] In some embodiments of this application, please refer to Figure 2 and Figure 13 The first connecting part 13 includes a plurality of mounting holes arranged sequentially along the circumference of the housing connector 1. The mounting holes can be used to insert screws, thereby realizing multi-point connection between the housing connector 1 and the housing body 4 and improving the connection reliability between the two.

[0068] In some embodiments of this application, please refer to Figure 9 The housing connector 1 is provided with a second sealing element 12 on the side facing the housing body 4, which can prevent the connection gap between the housing connector 1 and the housing body 4, realize the reliable sealing between the two, and prevent the gas inside the accommodating cavity 21 from flowing out from other gaps outside the opening 11, thus affecting the leakage monitoring results.

[0069] It should be noted that the second sealing element 12 can be an annular sealing gasket or an annular sealing ring. As long as it can achieve circumferential connection sealing between the housing connector 1 and the housing body 4, it can achieve the purpose of this application.

[0070] In some embodiments of this application, please refer to Figure 1 , Figure 5 and Figure 12 The housing connector 1 and the sealing member 3 are respectively disposed at both ends of the pipeline receiving member 2, and the two ends of the pipeline receiving member 2 are respectively sealed to the housing connector 1 and the sealing member 3, thereby forming a sealed receiving cavity 21 inside the pipeline receiving member 2. The receiving cavity 21 can only allow gas to flow through the opening 11, which helps to ensure the reliability of detecting leakage inside the receiving cavity 21 by the detection sensor 6 already in the internal cavity 41.

[0071] In the above embodiments, since the pipe housing 2 needs to have a certain length to cover the connection area between the internal pipe 51 and the external pipe 52, the pipe housing 2 protrudes too much from the main body of the housing 4, which is not convenient for packaging the equipment after production.

[0072] To address the aforementioned issues, please refer to some embodiments of this application. Figure 9 , Figure 15 , Figure 16 , Figure 17 and Figure 18 The pipe housing 2 is a retractable structure. When the pipe connection protection assembly is pre-installed on the housing body 4, the pipe housing 2 can be in a retracted state, minimizing its size and thus facilitating product packaging. Figure 15 As shown. After connecting the internal pipe 51 and the external pipe 52 of the product, the pipe receiving member 2 can be extended outward so that the receiving cavity 21 of the pipe receiving member 2 can wrap and protect the connection area of ​​the pipe, as shown. Figures 16 to 18 As shown.

[0073] It should be noted that the retractable pipe housing 2 can be made by sliding connection of multiple rigid sleeves or by deformable flexible material. As long as the retraction of the pipe housing 2 can be achieved and the sealing performance of the accommodating cavity 21 can be guaranteed, the purpose of this application can be achieved.

[0074] In some embodiments of this application, please refer to Figure 9 The pipeline housing 2 includes a retractable and foldable flexible sleeve 22, the interior of which forms an adjustable-volume accommodating cavity 21. Since the flexible sleeve 22 can be integrally injection molded from a flexible material, there are no assembly gaps, ensuring the reliable sealing performance of the pipeline housing 2 itself. Furthermore, because the material of the flexible sleeve 22 has a cushioning effect, it can absorb vibrations of the pipeline assembly 5 during operation, significantly reducing the adverse effects of vibration on the connection area of ​​the pipeline assembly 5, and effectively reducing the noise level during equipment operation.

[0075] In some embodiments of this application, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 15 , Figure 16 , Figure 17 and Figure 18 The pipe receiving component 2 is provided with a second connecting part 23 at one end facing the sealing component 3. The second connecting part 23 is used for detachable connection with the sealing component 3. When connecting the external pipe 52 after the sale, the external pipe 52 can be connected to the internal pipe 51 after the sealing component 3 is removed, which can improve the convenience of after-sales installation of the product.

[0076] In some embodiments of this application, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The sealing member 3 includes a detachably connected first sealing plate 33 and a second sealing plate 34, which are formed between the contact surfaces of the first sealing plate 33 and the second sealing plate 34 through a hole 31, so that the first sealing plate 33 and the second sealing plate 34 can clamp and fix the pipe body from both sides of the pipeline. The first sealing plate 33 and the second sealing plate 34 are each provided with a third connecting part that is adapted to the second connecting part 23, so that the second connecting part 23 can achieve a sealed connection with the first sealing plate 33 and the second sealing plate 34 respectively.

[0077] It should be noted that the connection between the second connecting part 23 and the third connecting part can be achieved by screw connection or snap connection. As long as the sealing connection between the pipeline receiving part 2 and the sealing part 3 and between the first sealing plate 33 and the second sealing plate 34 can be achieved, the purpose of this application can be achieved.

[0078] In some embodiments of this application, please refer to Figure 3 , Figure 4 as well as Figures 6 to 10 The second connecting part 23 includes a first snap-fit ​​structure 231, and the third connecting part includes a second snap-fit ​​structure adapted to the first snap-fit ​​structure 231. Through the cooperation of the first snap-fit ​​structure 231 and the second snap-fit ​​structure, the first sealing plate 33 and the second sealing plate 34 can be snapped onto the second connecting part 23.

[0079] In some embodiments of this application, please refer to Figure 3 , Figure 4 as well as Figures 6 to 10 The first snap-fit ​​structure 231 or the second snap-fit ​​structure is a guide groove. The extension direction of the guide groove is perpendicular to the axial direction of the pipeline. It can not only realize the snap-fit ​​connection between the first sealing plate 33, the second sealing plate 34 and the second connecting part 23, but also facilitate the sliding assembly guidance of the first sealing plate 33 and the second sealing plate 34, so that the first sealing plate 33 and the second sealing plate 34 respectively apply a clamping force perpendicular to the axial direction of the pipeline to both sides of the pipeline.

[0080] As a specific embodiment of this application, please refer to Figure 3 and Figure 4 The second snap-fit ​​structure provided on the first sealing plate 33 is a first guide groove 331 provided on the back of the first sealing plate 33. The second snap-fit ​​structure provided on the second sealing plate 34 is a second guide groove 341 provided on the back of the second sealing plate 34. The first snap-fit ​​structure 231 provided on the second connecting part 23 is a guide rib extending along the sliding docking direction of the first sealing plate 33 and the second sealing plate 34 (i.e., perpendicular to the pipeline axis). Through the sliding cooperation of the guide rib with the first guide groove 331 and the second guide groove 341, the sliding assembly guidance of the first sealing plate 33 and the second sealing plate 34 can be realized.

[0081] In some embodiments of this application, please refer to Figure 3 , Figure 4 as well as Figures 6 to 10 The second connecting part 23 also includes a third snap-fit ​​structure 232 arranged along its circumference. The third connecting part on the first sealing plate 33 also includes a first limiting part 332 arranged along its circumferential edge. The third connecting part on the second sealing plate 34 also includes a second limiting part 342 arranged along its circumferential edge. The first limiting part 332 and the second limiting part 342 surround each other to form a fourth snap-fit ​​structure that is adapted to the third snap-fit ​​structure 232, which can realize circumferential clamping and sealing between the edge of the sealing member 3 and the edge of the second connecting part 23.

[0082] As a specific embodiment of this application, both the first limiting part 332 and the second limiting part 342 include limiting grooves for engaging with the third snap-fit ​​structure 232, so that the edge of the second connecting part 23 is embedded in the edges of the first sealing plate 33 and the second sealing plate 34, such as Figure 10 As shown, this achieves a reliable sealed connection between the sealing element 3 and the pipeline housing 2.

[0083] In some embodiments of this application, please refer to Figure 4 , Figure 6 , Figure 9 and Figure 11 The first sealing plate 33 is provided with a first positioning part 333 on the first side facing the second sealing plate 34, and the second sealing plate 34 is provided with a second positioning part 343 on the side facing the first sealing plate 33. Through the concave-convex connection of the first positioning part 333 and the second positioning part 343, the assembly positioning between the first sealing plate 33 and the second sealing plate 34 can be realized, and the embedded connection between the first sealing plate 33 and the second sealing plate 34 can be realized.

[0084] Specifically, one of the positioning parts 333 and 343 is a protrusion on the contact surface of the two sealing plates, and the other is a recess on the contact surface of the two sealing plates. There can be multiple positioning parts 333 and 343, arranged sequentially along the length of the first sealing plate 33 and the second sealing plate 34, such as... Figure 4 and Figure 6 As shown, this can improve the positioning accuracy and reliability between the two.

[0085] In some embodiments of this application, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 , Figure 11 To improve the connection reliability between the first sealing plate 33 and the second sealing plate 34, a first snap-fit ​​portion 334 is provided on the side of the first sealing plate 33 facing the second sealing plate 34, and a second snap-fit ​​portion 344 is provided on the side of the second sealing plate 34 facing the first sealing plate 33. Through the engagement of the first snap-fit ​​portion 334 and the second snap-fit ​​portion 344, the first sealing plate 33 and the second sealing plate 34 can be tightly connected together, thereby clamping both sides of the pipeline. Specifically, the first snap-fit ​​portion 334 is a snap-fit ​​plate protruding from the front of the first sealing plate 33, and the second snap-fit ​​portion 344 is a buckle facing the first sealing plate 33. By hooking the buckle onto the snap-fit ​​plate, a clamping force can be applied to the first sealing plate 33 and the second sealing plate 34 respectively. Multiple buckles can be arranged sequentially along the length of the second sealing plate 34, enabling multi-point connection with the first sealing plate 33.

[0086] In some embodiments of this application, when the closure 3 includes a first sealing plate 33 and a second sealing plate 34 disposed opposite to each other, the first sealing member 32 can be an annular sealing ring, or it can be formed by mating two semi-circular sealing elements (i.e., the first sealing element 321 and the second sealing element 322), such as... Figure 2 As shown. The first sealing element 321 and the second sealing element 322 are respectively embedded on the first sealing plate 33 and the second sealing plate 34, and then the external pipeline 52 is clamped and interference-fitted, which can improve the ease of assembly between the first sealing element 32 and the external pipeline 52.

[0087] In some embodiments of this application, please refer to Figure 9 and Figure 10The flexible sleeve 22 has a protruding edge 221 at one end facing the second connecting part 23. The second connecting part 23 has a fifth snap-fit ​​structure 233 for embedding with the protruding edge 221, which can achieve a snap-fit ​​and sealed connection between the flexible sleeve 22 and the second connecting part 23. It can be understood that the other end of the flexible sleeve 22 can also be embedded to form a sealed connection with the housing connector 1, which will not be described in detail here.

[0088] In other embodiments of this application, the pipe housing 2 is not a retractable structure. Before product packaging, the entire pipe connection protection assembly can be installed in reverse inside the housing body 4, such as... Figure 19 and Figure 20 As shown, this is to prevent the pipe connection protection component from protruding from the main body 4 of the housing and affecting the product packaging. After completing the after-sales pipe connection, the pipe connection protection component is then installed upright to achieve wrapping protection of the pipe connection area, as shown. Figure 21 As shown.

[0089] In some embodiments of this application, please refer to Figure 12 , Figure 13 and Figure 21 The pipeline connection protection assembly includes a first housing and a second housing that are detachably connected, so as to facilitate the assembly between the pipeline connection protection assembly and the pipeline assembly 5 when installing the external pipeline 52 after the sale.

[0090] The first housing includes an integrated first housing connecting piece 14, a first pipeline receiving piece 24, and a first sealing piece 35. The second housing includes an integrated second housing connecting piece 15, a second pipeline receiving piece 25, and a second sealing piece 36. The first housing connecting piece 14 and the second housing connecting piece 15 are connected to form a housing connecting piece 1. The first pipeline receiving piece 24 and the second pipeline receiving piece 25 are connected to form a pipeline receiving piece 2. The first sealing piece 35 and the second sealing piece 36 are connected to form a sealing piece 3. Similarly, a receiving cavity 21 can be formed between the first housing and the second housing, thereby achieving the enclosure and protection of the connection area of ​​the pipeline assembly 5. It is understood that, in order to ensure that gas can only flow through the opening 11 in the receiving cavity 21, the first housing and the second housing are sealed together to prevent gas leakage from the connection gap between the first housing and the second housing.

[0091] When the first housing includes an integrated first housing connecting piece 14, a first pipeline receiving piece 24, and a first sealing piece 35, and the second housing includes an integrated second housing connecting piece 15, a second pipeline receiving piece 25, and a second sealing piece 36, the assembly steps between the housing connecting piece 1, the pipeline receiving piece 2, and the sealing piece 3 can be simplified.

[0092] Please see Figures 1 to 21The second aspect of this application provides a device housing, including the pipe connection protection assembly described in the above embodiments, and a housing body 4. The housing body 4 has an internal cavity 41. The pipe connection protection assembly is sealed to the housing body 4 via a housing connector 1, and an opening 11 communicates with the internal cavity 41, allowing the internal pipe 51 in the internal cavity 41 to extend into the receiving cavity 21 and connect with the external pipe 52. After connection, the pipe connection protection assembly can protect the connection area outside the housing body 4.

[0093] In some embodiments of this application, when a retractable pipe housing 2 is used, a recessed cavity 42 is provided on the outer surface of the housing body 4, so that the pipe connection protection component in the contracted state is embedded in the housing body 4, thereby reducing the overall packaging size of the product.

[0094] Please see Figures 1 to 21 The third aspect of this application provides a leak detection system, including the device housing described in the above embodiments, and a piping assembly 5. The piping assembly 5 includes an internal pipe 51, an external pipe 52, and a pipe connector 53. The internal pipe 51 and the external pipe 52 are connected through the pipe connector 53, and the pipe connector 53 is located inside the accommodating cavity 21, so that the piping connection protection assembly can wrap and protect the connection area between the internal pipe 51 and the external pipe 52 through the accommodating cavity 21. The piping assembly 5 is used to transport the target fluid. The internal cavity 41 is provided with a detection sensor 6 for detecting whether the target fluid is leaking. Once there is a leak of the target fluid in the pipe connection area inside the accommodating cavity 21, since the accommodating cavity 21 is connected to the internal cavity 41, the detection sensor 6 in the internal cavity 41 can monitor and report the leak, so that technicians can repair the leak.

[0095] It should be noted that the target fluid can be a volatile fluid, such as refrigerant or fuel gas. A leak detection system can prevent safety hazards caused by untimely detection of leaks in the target fluid.

[0096] In some embodiments of this application, please refer to Figures 15 to 21 When there are multiple pipe assemblies 5, the pipe connection protection assembly is provided with multiple through holes 31 to facilitate the installation of multiple pipe assemblies 5. When the diameters of multiple pipe assemblies 5 (such as pipe assembly 1 5a and pipe assembly 2 5b) are different, the dimensions of multiple through holes 31 and multiple first seals 32 are also matched to the various pipe diameters.

[0097] Please see Figures 1 to 21The fourth aspect of this application provides an air conditioning device, including the leak detection system described in the above embodiments, where the target fluid is refrigerant. Since refrigerant is flammable, a leak could pose a safety hazard. Specifically, the air conditioning device (such as a residential unit) includes an indoor unit and an outdoor unit. This application uses a pipe connection protection component to connect the indoor and outdoor unit connection pipe area to the interior of the indoor unit housing, and to wrap and protect the connection area. If the connection area becomes loose and refrigerant leaks, the leaked refrigerant can be directed to an internal cavity 41 equipped with an evaporator and a detection sensor 6, preventing refrigerant from leaking into the environment and ensuring that any abnormal leaks in the pipe connection area can be detected and alarmed promptly by the detection sensor 6.

[0098] In some embodiments of this application, the inner wall of the accommodating cavity 21 is provided with a heat insulation layer (such as a heat insulation sponge pad), which can insulate the connection area of ​​the pipeline assembly 5, prevent condensation from forming on its surface and flowing into the inner cavity 41, and affect the reliability of other components installed inside the equipment housing.

[0099] In some embodiments of this application, please refer to Figures 14 to 18 When the pipe connection protection assembly uses the retractable pipe receiver 2, the method of using the pipe connection protection assembly is as follows:

[0100] Step 1: During pre-assembly, the housing connector 1 is connected to the recessed cavity 42 on the housing body 4, squeezing the pipeline accommodating component 2 into a contracted state, so that the first sealing plate 33 and the second sealing plate 34 are respectively clamped on both sides of the internal pipeline 51, as shown. Figure 15 As shown. At this time, the outlet of the internal pipe 51 can be blocked with a sealing plug to prevent impurities from entering the internal pipe 51.

[0101] Step Two: When connecting the external pipes 52 to the outer casing 4 after-sales service, open the first sealing plate 33 and the second sealing plate 34, and connect the internal pipe 51 and the external pipe 52 through the pipe connector 53, such as... Figure 16 As shown;

[0102] Step 3: Extend the pipe housing 2 outwards so that the housing 21 covers and protects the connection area between the internal pipe 51 and the external pipe 52, such as... Figure 17 As shown;

[0103] Step 4: Connect the first sealing plate 33 and the second sealing plate 34 to the pipeline receiving component 2, clamping the external pipeline 52 while simultaneously sealing the receiving cavity 21, as shown. Figure 18 As shown.

[0104] In other embodiments of this application, please refer to Figures 19 to 21 When the pipe connection protection assembly uses a non-extendable pipe housing 2, the method of using the pipe connection protection assembly is as follows:

[0105] Step 1: Install the first and second housings in reverse order within the internal cavity 41 of the housing body 4, connecting the housing connector 1 to the inner wall of the housing body 4, as follows: Figure 19 and Figure 20 As shown; at this time, the outlet of the internal pipe 51 can be blocked with a sealing plug to prevent impurities from entering the internal pipe 51.

[0106] Step 2: When connecting the external pipes 52 to the outside of the main body 4 after the service, remove the first and second housings from the inner wall of the internal cavity 41; and connect the internal pipes 51 and the external pipes 52 through the pipe joints 53.

[0107] Step 3: Install the first and second housings onto the outer surface of the housing body 4, facing forward, as follows: Figure 21 As shown, the connection area between the internal pipe 51 and the external pipe 52 is wrapped, protected, and sealed.
