[0034] Reference to "embodiments" in this context means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will understand explicitly and implicitly that the embodiments described herein can be combined with other embodiments.

[0035] The present application provides an electrical appliance 300. Refer to Figure 1 and Figure 3 , Figure 1 is a schematic structural diagram of an embodiment of the electrical appliance provided by the present application, Figure 3 is Figure 1 a schematic exploded view of the pipeline assembly in the electrical appliance shown.

[0036] The electrical appliance 300 can be an electrical appliance such as an air conditioner, a dishwasher, or a refrigerator. The flow and throttling of liquids such as refrigerant or water flow inside it are all connected by pipelines. There are various components in the installation space inside the electrical appliance 300, that is, the installation space of the electrical appliance 300 is very compact, and the space available for installing structural components such as pipelines is very limited, which greatly restricts the installation of pipelines.

[0037] Specifically, the electrical appliance 300 includes a pipeline assembly 100 and a housing assembly 200. The housing assembly 200 has an installation space for installing a plurality of components. For example, a compressor, a motor, a pump, and pipelines connecting between a plurality of components are provided inside the housing assembly 200. The pipeline assembly 100 is disposed in the housing assembly 200, and the pipeline assembly 100 is connected between at least two components.

[0038] The pipeline assembly 100 includes a first pipeline 10, a second pipeline 20, and a third pipeline 30. The first pipeline 10 and the second pipeline 20 are fixedly arranged, and the third pipeline 30 is assembled between the fixedly arranged first pipeline 10 and the second pipeline 20, and the first pipeline 10, the second pipeline 20, and the third pipeline 30 are communicated with each other.

[0039] The first pipeline 10 is fixed to the housing assembly 200 or fixedly connected to a first component inside or outside the housing assembly 200, and the second pipeline 20 is fixed to the housing assembly 200 or fixedly connected to a second component inside or outside the housing assembly 200, so that the positions of the first pipeline 10 and the second pipeline 20 are kept fixed.

[0040] Specifically, as Figure 3 shown, the axis of the second pipeline 20 is arranged parallel to the axis of the first pipeline 10, that is, the first pipeline 10 and the second pipeline 20 are arranged in parallel and offset; and the ports of the second pipeline 20 and the first pipeline 10 face in opposite directions, that is, the ports of the second pipeline 20 and the first pipeline 10 can face each other or face away from each other.

[0041] For example, if the second pipeline 20 and the first pipeline 10 coincide in the direction perpendicular to the axis of the first pipeline 10, the ports of the second pipeline 20 and the first pipeline 10 face away from each other; if the second pipeline 20 and the first pipeline 10 do not coincide in the direction perpendicular to the axis of the first pipeline 10, the ports of the second pipeline 20 and the first pipeline 10 face each other, that is, face each other face to face.

[0042] The first pipeline 10 can be a straight pipe, or a section of a straight pipe in a pipeline. The first pipeline 10 is located at the end of the pipeline and is used to connect to other pipelines. The pipeline can also have curved pipe sections, other straight pipe sections, or variable diameter pipe sections, etc.; the second pipeline 20 can be a straight pipe, or a section of a straight pipe in a pipeline. The second pipeline 20 is located at the end of the pipeline and is used to connect to other pipelines. The pipeline can also have curved pipe sections, other straight pipe sections, or variable diameter pipe sections, etc. The present application does not make specific limitations on this.

[0043] The current problem is that a pipeline is needed to connect the first pipeline 10 and the second pipeline 20. The first pipeline 10, the second pipeline 20, and the pipeline connecting the first pipeline 10 and the second pipeline 20 are usually metal pipes, such as copper pipes, copper alloy pipes, aluminum pipes, aluminum alloy pipes, or stainless steel pipes, etc. They all have the advantages of good chemical stability, corrosion resistance, and long service life; in the currently adopted solutions, usually two metal pipes are used to connect the first pipeline 10 and the second pipeline 20.

[0044] As Figure 2 shown, Figure 2It is a schematic diagram of the connection structure of the existing commonly used first pipeline and second pipeline.

[0045] Refer to Figure 2 and Figure 3 . A first metal pipe 1 and a second metal pipe 2 are connected between the first pipeline 10 and the second pipeline 20. The first end of the first metal pipe 1 is connected to the port of the first pipeline 10, so that the port of the second end of the first metal pipe 1 faces the same direction as the port of the second pipeline 20. The two ends of the second metal pipe 2 are respectively connected to the second end of the first metal pipe 1 and the port of the second pipeline 20.

[0046] As Figure 2 shown, both the first metal pipe 1 and the second metal pipe 2 are pipelines arranged in a meandering manner, resulting in longer pipelines for the first metal pipe 1 and the second metal pipe 2, larger occupied space, and also larger required installation space. It is not conducive to installing the first metal pipe 1 and the second metal pipe 2 between the first pipeline 10 and the second pipeline 20 within the installation space of the housing assembly 200. This installation operation is difficult and has low efficiency.

[0047] Refer to Figure 1 and Figure 3 . In this application, the pipeline assembly 100 further includes a third pipeline 30. The third pipeline 30 includes a first pipe orifice section 32 and a second pipe orifice section 34. The axis of the first pipe orifice section 32 is arranged parallel to the axis of the second pipe orifice section 34. The first pipe orifice section 32 is used for plugging and assembling with the first pipeline 10, and the second pipe orifice section 34 is used for plugging and assembling with the second pipeline 20.

[0048] Wherein, the first pipe orifice section 32 is plugged into the first pipeline 10 and moves a first plugging stroke C relative to the first pipeline 10. The first plugging stroke C is the plugging distance between the first pipe orifice section 32 and the first pipeline 10, so that the port of the second pipe orifice section 34 can face the port of the second pipeline 20, that is, the second pipe orifice section 34 can be aligned with the second pipeline 20 and coaxial. After the second pipe orifice section 34 is aligned with the second pipeline 20, the second pipe orifice section 34 is plugged into the second pipeline 20, so that the first pipe orifice section 32 is plugged into the first pipeline 10 and the second pipe orifice section 34 is plugged into the second pipeline 20 at the same time, that is, the third pipeline 30 is assembled between the first pipeline 10 and the second pipeline 20, and the pipeline assembly can be conveniently completed in a relatively compact space, effectively improving the assembly efficiency.

[0049] In this embodiment, when the axis of the first pipe orifice section 32 is parallel or collinear with the axis of the first pipeline 10, in the axial direction of the first pipeline 10, there is a first distance A between the port of the first pipe orifice section 32 and the port of the second pipe orifice section 34, and there is a second distance B between the port of the first pipeline 10 and the port of the second pipeline 20, and the first distance A is greater than the second distance B; the first pipe orifice section 32 and the first pipeline 10 have a matching first insertion stroke C; the difference between the first distance A and the first insertion stroke C is less than or equal to the second distance B.

[0050] Referring to Figures 4 to 7 , Figure 4 is Figure 3 a schematic diagram of the insertion and assembly structure of the first pipeline and the first pipe orifice section in the pipeline assembly, Figure 5 is Figure 4 a schematic top view structure diagram of the pipeline assembly, Figure 6 is Figure 4 a schematic diagram of the structure where the second pipe orifice section rotates to align with and be inserted into the second pipeline in the pipeline assembly, Figure 7 is Figure 5 a schematic top view structure diagram of the pipeline assembly.

[0051] In this application, the specific process of installing the third pipeline 30 between the first pipeline 10 and the second pipeline 20 is as follows: As Figure 4 shown, align the first pipe orifice section 32 with the first pipeline 10, that is, the first pipe orifice section 32 and the first pipeline 10 are arranged facing each other and are generally coaxial, and the second pipe orifice section 34 and the second pipeline 20 are misaligned. At this time, since the first distance A is greater than the second distance B, the second pipe orifice section 34 and the second pipeline 20 interfere with each other and cannot be aligned. Then insert the first pipe orifice section 32 into the first pipeline 10 along the first insertion stroke C, that is, the overlapping distance caused by the insertion between the first pipe orifice section 32 and the first pipeline 10 is the first insertion stroke C. Then, since the difference between the first distance A and the first insertion stroke C is less than or equal to the second distance B, the interference state between the second pipe orifice section 34 and the second pipeline 20 can be eliminated; As Figure 5 shown, Figure 5 the arrow shown in Figure 6 and Figure 7 represents the rotation direction of the third pipeline 30. After rotating the third pipeline 30 around the axis of the first pipeline 10 by a certain angle, the second pipe orifice section 34 can be aligned with and coaxial with the second pipeline 20; Then as Figure 6 and Figure 7 shown, drive the second pipe orifice section 34 to be inserted and assembled into the second pipeline 20 along the axis of the first pipeline 10, and the third pipeline 30 can be assembled between the first pipeline 10 and the second pipeline 20.

[0052] By defining that the first distance A of the third pipeline 30 is greater than the second distance B, and the first pipe orifice section 32 and the first pipeline 10 have a matching first insertion stroke C, and the difference between the first distance A and the first insertion stroke C is less than or equal to the second distance B, it is possible to first dock the first pipe orifice section 32 and the first pipeline 10, and by rotating the third pipeline 30 around the axis of the first pipeline 10, the second pipe orifice section 34 can be aligned with the second pipeline 20, and then drive the second pipe orifice section 34 to be inserted and assembled into the second pipeline 20, so as to realize the interference-free assembly between the second pipe orifice section 34 and the second pipeline 20. The installation space required for the third pipeline 30 is small, and the pipeline assembly in a compact space can be realized, effectively reducing the installation difficulty and improving the installation efficiency. Therefore, the pipeline assembly 100 provided by the present application can complete the pipeline assembly between the first pipeline 10 and the second pipeline 20 in a compact space, and has a low installation difficulty and a high installation efficiency.

[0053] As Figure 3 shown, the third pipeline 30 further includes a straight tube 36 connected between the first pipe orifice section 32 and the second pipe orifice section 34, and both ends of the straight tube 36 are arc-transitionally connected to the first pipe orifice section 32 and the second pipe orifice section 34 respectively.

[0054] In this embodiment, the first pipe orifice section 32 is on one side of the second pipe orifice section 34 along the axis extension direction, that is, there is no overlapping part between the first pipe orifice section 32 and the second pipe orifice section 34 in the axis extension direction, and the axis of the straight tube 36 is perpendicular to the axis of the first pipe orifice section 32 and the axis of the second pipe orifice section 34. In other words, the third pipeline 30 is a non-roundabout pipeline, and thus the pipeline of the third pipeline 30 is relatively short and the pipeline cost is relatively low, which is beneficial to reducing the costs of the pipeline assembly 100 and the electrical appliance 300.

[0055] Optionally, the first pipe orifice section 32 is on one side of the second pipe orifice section 34 along the axis extension direction, and the axis of the straight tube 36 is inclined between the axis of the first pipe orifice section 32 and the axis of the second pipe orifice section 34.

[0056] Optionally, there is an overlapping part between the first pipe orifice section 32 and the second pipe orifice section 34 in the axis extension direction, and the straight tube 36 is connected between the first pipe orifice section 32 and the second pipe orifice section 34, which is beneficial to increasing the pipeline length of the third pipeline 30; further, a roundabout pipe section is arranged between the first pipe orifice section 32 and the second pipe orifice section 34, which can further increase the pipeline length of the third pipeline 30, so as to facilitate the liquid to flow through the third pipeline 30 for heat dissipation or heating, etc.

[0057] In this embodiment, as Figure 3As shown, the second pipe orifice section 34 and the second pipeline 20 have a matching second insertion stroke D. Since the first insertion stroke C is greater than the second insertion stroke D, after the second pipe orifice section 34 and the second pipeline 20 are inserted and assembled, the first pipe orifice section 32 and the first pipeline 10 can be kept in the inserted and assembled state without falling off.

[0058] Optionally, the first insertion stroke C can also be less than or equal to the second insertion stroke D, and with the help of an external force or an external object, the first pipe orifice section 32 and the first pipeline 10 can be kept in the inserted and assembled state without falling off. For example, the user holds the third pipeline 30 by hand, or uses a fixture to clamp the third pipeline 30, so that the first pipe orifice section 32 and the first pipeline 10 are kept in the inserted and assembled state.

[0059] The first pipe orifice section 32 is inserted and assembled with the first pipeline 10, that is, one end of the first pipe orifice section 32 is inserted into one end of the first pipeline 10, or one end of the first pipeline 10 is inserted into one end of the first pipe orifice section 32; the second pipe orifice section 34 is inserted and assembled with the second pipeline 20, that is, one end of the second pipe orifice section 34 is inserted into one end of the second pipeline 20, or one end of the second pipeline 20 is inserted into one end of the second pipe orifice section 34.

[0060] In this embodiment, there is a clearance fit between the first pipe orifice section 32 and the first pipeline 10 to reduce the assembly difficulty between the first pipe orifice section 32 and the first pipeline 10; there is a clearance fit between the second pipe orifice section 34 and the second pipeline 20 to reduce the assembly difficulty between the second pipe orifice section 34 and the second pipeline 20.

[0061] In other embodiments, there can also be an interference fit or an interference fit such as an interference fit between the first pipe orifice section 32 and the first pipeline 10, and there can also be an interference fit or an interference fit such as an interference fit between the second pipe orifice section 34 and the second pipeline 20, and by heating the ports of the outer pipelines at each connection, they are inserted and assembled with another pipeline.

[0062] Further, in this embodiment, after the first pipe orifice section 32 is inserted and assembled with the first pipeline 10, and the second pipe orifice section 34 is inserted and assembled with the second pipeline 20, the first pipe orifice section 32 is further welded to the first pipeline 10, and the second pipe orifice section 34 is further welded to the second pipeline 20 to enhance the connection strength and airtightness between the third pipeline 30 and the first pipeline 10 and the second pipeline 20, and the pipeline assembly 100 has fewer welds compared to the Figure 2 shown structure, which can further improve the installation efficiency of the pipeline assembly 100.

[0063] Optionally, locking nuts are also provided on the first pipeline 10 and the second pipeline 20. After the second pipe orifice section 34 is inserted and assembled with the second pipeline 20, one locking nut locks the first pipe orifice section 32 and the first pipeline 10, and the other locking nut locks the second pipe orifice section 34 and the second pipeline 20.

[0064] Refer to Figure 8 , Figure 8 which Figure 4 is the first enlarged structural schematic diagram of the E region in the pipeline assembly.

[0065] One of the first pipeline 10 and the first pipe orifice section 32 includes a first sleeve section 320, a first transition section 322, and a first straight tube section 324 that are coaxially arranged. The inner diameter of the first sleeve section 320 is different from the inner diameter of the first straight tube section 324. The length of the first sleeve section 320 along the axis is the first insertion stroke C. The other of the first pipeline 10 and the first pipe orifice section 32 is inserted and matched with the first sleeve section 320 and is limited and blocked by the first transition section 322.

[0066] Among them, both the first pipeline 10 and the first pipe orifice section 32 have a uniform wall thickness.

[0067] For example, if the inner diameter of the first sleeve section 320 is greater than the inner diameter of the first straight tube section 324, it forms a flared structure; or if the inner diameter of the first sleeve section 320 is less than the inner diameter of the first straight tube section 324, it forms a reduced diameter structure.

[0068] In this embodiment, as Figure 8 shown, the first pipe orifice section 32 includes a first sleeve section 320, a first transition section 322, and a first straight tube section 324 that are coaxially arranged. The inner diameter of the first sleeve section 320 is greater than the inner diameter of the first straight tube section 324. Then, one end of the first pipe orifice section 32 facing the first pipeline 10 is in a flared structure. The first pipeline 10 is a straight tube with a constant inner diameter. One end of the first sleeve section 320 is inserted and assembled into one end of the straight tube, that is, one end of the straight tube is sleeved inside the first sleeve section 320 and is blocked by the first transition section 322, thereby defining the first insertion stroke C of the cooperation between the first pipe orifice section 32 and the first pipeline 10.

[0069] Optionally, one end of the first pipe orifice section 32 facing the first pipeline 10 is in a reduced diameter structure. The first pipeline 10 is a straight tube. Then, one end of the first sleeve section 320 is inserted into one end of the straight tube, and one end of the straight tube is also blocked by the first transition section 320.

[0070] Optionally, one end of the first pipe orifice section 32 facing the first pipeline 10 is in a flared structure, and one end of the first pipeline 10 facing the first pipe orifice section 32 is in a reduced diameter structure. The flared structure and the reduced diameter structure are inserted and matched with each other.

[0071] In the above enumeration of this embodiment, the structures of the first pipeline 10 and the first pipe orifice section 32 can be interchanged.

[0072] Refer to Figure 9 , Figure 9 which Figure 4Schematic diagram of the second enlarged structure of region E in the pipeline assembly.

[0073] In other embodiments, referring to Figure 9 , a first stop portion 102 is provided on the outer wall or inner wall of one of the first pipeline 10 and the first pipe orifice section 32. The distance between the first stop portion 102 and the port of this one is the first insertion stroke C, and the end of the other of the first pipeline 10 and the first pipe orifice section 32 is stopped by the first stop portion 102.

[0074] The first stop portion 102 is a convex ring or a convex point.

[0075] As Figure 9 shown, the first stop portion 102 is a convex point provided on the outer wall of the first pipeline 10. One end of the first pipe orifice section 32 is inserted into the first pipeline 10, and is sleeved outside the first pipeline 10 and stopped by the first stop portion 102. The distance between the first stop portion 102 and the port of the first pipeline 10 is the first insertion stroke C.

[0076] Alternatively, the first stop portion 102 is a convex ring provided on the inner wall of the first pipeline 10. Then one end of the first pipe orifice section 32 is sleeved inside the first pipeline 10, and its end is stopped by the first stop portion 102.

[0077] In the above enumeration of this embodiment, the structures of the first pipeline 10 and the first pipe orifice section 32 can be interchanged.

[0078] Referring to Figure 10 , Figure 10 is Figure 6 Schematic diagram of the first enlarged structure of region F in the pipeline assembly.

[0079] One of the second pipeline 20 and the second pipe orifice section 34 includes a second sleeve section 22, a second transition section 24 and a second straight section 26 arranged coaxially. The inner diameter of the second sleeve section 22 is different from the inner diameter of the second straight section 26. The length of the second sleeve section 22 along the axis is the second insertion stroke D, and the other of the second pipeline 20 and the second pipe orifice section 34 is inserted and matched with the second sleeve section 22.

[0080] Among them, both the second pipeline 20 and the second pipe orifice section 34 have a uniform wall thickness.

[0081] For example, if the inner diameter of the second sleeve section 22 is larger than the inner diameter of the second straight section 26, a flared structure is formed; or if the inner diameter of the second sleeve section 22 is smaller than the inner diameter of the second straight section 26, a reduced diameter structure is formed.

[0082] In this embodiment, as Figure 10As shown, the second pipeline 20 includes a second sleeve section 22, a second transition section 24, and a second straight section 26 that are coaxially arranged. The inner diameter of the second sleeve section 22 is larger than that of the second straight section 26. Then, one end of the second pipeline 20 facing the third pipeline 30 has a flared structure. The second pipe orifice section 34 is a straight pipe with a constant inner diameter. One end of the second pipeline 20 is inserted and assembled into the straight pipe, that is, one end of the straight pipe is sleeved inside the second pipeline 20 and is blocked by the second transition section 24, thereby defining a second insertion stroke D for the cooperation between the second pipe orifice section 34 and the second pipeline 20.

[0083] Optionally, one end of the second pipeline 20 facing the second pipe orifice section 34 has a reduced diameter structure. The second pipe orifice section 34 is a straight pipe. Then, one end of the second sleeve section 22 is inserted into one end of the straight pipe, and one end of the straight pipe is also blocked by the second transition section 24.

[0084] Optionally, one end of the second pipeline 20 facing the second pipe orifice section 34 has a flared structure, and one end of the second pipe orifice section 34 facing the second pipeline 20 has a reduced diameter structure.

[0086] Refer to Figure 11 , Figure 11 which is Figure 6 the second enlarged structural schematic diagram of the F area in the pipeline assembly.

[0087] A second stop portion 342 is provided on the outer wall or the inner wall of one of the second pipeline 20 and the second pipe orifice section 34. The distance between the second stop portion 342 and the port of this one is the second insertion stroke D. The end of the other of the second pipeline 20 and the second pipe orifice section 34 is blocked by the second stop portion 342.

[0089] As Figure 11 shown, the second stop portion 342 is a convex point provided on the outer wall of the second pipe orifice section 34. One end of the second pipeline 20 is inserted into the second pipe orifice section 34 and is sleeved outside the second pipe orifice section 34 and is blocked by the second stop portion 342. The distance between the second stop portion 342 and the port of the second pipe orifice section 34 is the second insertion stroke D.

[0090] Alternatively, the second stop portion 342 is a convex ring provided on the inner wall of the second pipe orifice section 34. Then, one end of the second pipeline 20 is sleeved inside the second pipe orifice section 34, and its end is blocked by the second stop portion 342.

[0091] In the above enumeration of this embodiment, the structures of the second pipe orifice section 34 and the second pipeline 20 can be interchanged.

[0092] Based on this, the present application further provides a connection method for a pipeline assembly 100. Refer to Figure 10 , Figure 10 which is a schematic flow chart of the connection method for the pipeline assembly provided by the present application. The connection method includes:

[0093] S10: Provide a first pipeline and a second pipeline with their positions unchanged.

[0094] Provide a first pipeline 10 and a second pipeline 20, wherein the first pipeline 10 and the second pipeline 20 are fixedly arranged, that is, the positions of the first pipeline 10 and the second pipeline 20 cannot be changed.

[0095] For example, the first pipeline 10 is fixed to the housing assembly 200 or fixedly connected to a first component inside or outside the housing assembly 200, and the second pipeline 20 is fixed to the housing assembly 200 or fixedly connected to a second component inside or outside the housing assembly 200, so that the positions of the first pipeline 10 and the second pipeline 20 are kept fixed.

[0096] The axis of the second pipeline 20 is arranged parallel to the axis of the first pipeline 10, that is, the first pipeline 10 and the second pipeline 20 are arranged in parallel and offset; and the ports of the second pipeline 20 and the first pipeline 10 face in opposite directions.

[0097] S20: Provide a third pipeline.

[0098] The third pipeline 30 includes a first pipe orifice section 32 and a second pipe orifice section 34. The axis of the first pipe orifice section 32 is arranged parallel to the axis of the second pipe orifice section 34. The first pipe orifice section 32 is used for assembling with the first pipeline 10, and the second pipe orifice section 34 is used for assembling with the second pipeline 20.

[0099] When the axis of the first pipe orifice section 32 is parallel or collinear with the axis of the first pipeline 10, in the axial direction of the first pipeline 10, there is a first distance A between the port of the first pipe orifice section 32 and the port of the second pipe orifice section 34, and there is a second distance B between the port of the first pipeline 10 and the port of the second pipeline 20. The first distance A is greater than the second distance B; the first pipe orifice section 32 and the first pipeline 10 have a matching first insertion stroke C; the difference between the first distance A and the first insertion stroke C is less than or equal to the second distance B; the second pipe orifice section 34 and the second pipeline 20 have a matching second insertion stroke D, and the first insertion stroke C is greater than the second insertion stroke D.

[0100] In this embodiment, the third pipeline 30 further includes a straight tube 36 connected between the first pipe orifice section 32 and the second pipe orifice section 34. The two ends of the straight tube 36 are respectively connected to the first pipe orifice section 32 and the second pipe orifice section 34 in an arc transition manner.

[0101] S30: Insert the first pipe orifice section into the first pipeline and move the first insertion stroke relative to the first pipeline.

[0102] The first pipe orifice section 32 is assembled with a clearance between it and the first pipeline 10. The first pipe orifice section 32 is inserted and assembled into the first pipeline 10 along the first insertion stroke C, which can eliminate the interference state between the second pipe orifice section 34 and the second pipeline 20, so as to facilitate the alignment of the second pipe orifice section 34 and the second pipeline 20.

[0103] S40: Rotate the third pipeline around the axis of the first pipeline so that the second pipe orifice section is aligned with and coaxial with the second pipeline.

[0104] The first pipe orifice section 32 is assembled with a clearance between it and the first pipeline 10, which can facilitate the rotation of the third pipeline 30 around the axis of the first pipeline 10, and then align the second pipe orifice section 34 with the second pipeline 20, that is, the axis of the second pipe orifice section 34 is collinear with the axis of the second pipeline 20.

[0105] S50: Drive the second pipe orifice section to be inserted and assembled into the second pipeline along the axis direction of the first pipeline.

[0106] The first pipe orifice section 32 is assembled with a clearance between it and the first pipeline 10, which can also facilitate driving the third pipeline 30 to move relative to the first pipeline 10 along the axis direction of the first pipeline, and then make the second pipe orifice section 34 be inserted and assembled into the second pipeline 20, where the second pipe orifice section 34 is assembled with a clearance between it and the second pipeline 20.

[0107] S60: Weld the first pipeline and the first pipe orifice section, and weld the second pipeline and the second pipe orifice section.

[0108] After the two ends of the third pipeline 30 are respectively inserted and assembled with the first pipeline 10 and the second pipeline 20, further weld the first pipeline 10 and the first pipe orifice section 32, and weld the second pipeline 20 and the second pipe orifice section 34 to enhance the connection strength and airtightness between the third pipeline 30 and the first pipeline 10 and the second pipeline 20.

[0109] Different from the prior art, the present application discloses an electrical appliance, its pipeline assembly, and a connection method for the pipeline assembly. By defining that the first pipe orifice section is inserted into the first pipeline and the first insertion stroke is moved relative to the first pipeline, the second pipe orifice section can be aligned with and coaxial with the second pipeline, and the second pipe orifice section is inserted into the second pipeline to install the third pipeline between the first pipeline and the second pipeline, so as to realize non-interference assembly between the second pipe orifice section and the second pipeline in a tight space. The installation space required for the third pipeline is small, and pipeline assembly in a compact space can be realized, effectively reducing the installation difficulty and improving the installation efficiency. Therefore, the pipeline assembly provided by the present application can complete pipeline assembly in a compact space, with low installation difficulty and high installation efficiency.

[0110] The above are only embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present application.
