Description

[Technical Field]

[0001] This application is filed based on and claims priority from a Chinese patent application bearing application number 202222078485.9 and filed on August 8, 2022, the entire contents of which are incorporated herein by reference. The present application relates to the technical field of air conditioning piping, for example, to through-wall pipe assemblies and air conditioners. [Background technology]

[0002] During the hot summer, many people prefer to stay in air-conditioned rooms, but while air-conditioned rooms can provide a relatively comfortable experience, such environments can also have a negative impact on the user's health. Because air-conditioned rooms are highly sealed and have poor air flow, users may experience symptoms such as stuffy nose, tinnitus, fatigue, and skin allergies over long periods of time, which are commonly considered to be "air-conditioning sickness."

[0003] To improve this situation, some air conditioner manufacturers have recently introduced air conditioner products with a fresh air function. This involves attaching an fresh air duct to the indoor unit of the air conditioner and placing the intake end of the fresh air duct outdoors, allowing fresh outdoor air to be introduced into the indoor environment through the fresh air duct, thereby improving the indoor environment and enhancing air quality.

[0004] When installing an air conditioner, the outdoor air duct must be passed through a hole drilled in the wall to the outside, and some of the pipelines (e.g., refrigerant piping, power supply lines, etc.) between the indoor and outdoor units of the air conditioner must also pass through this hole, so how to rationally arrange the outdoor air duct and pipelines is an important issue. Summary of the Invention [Problem to be solved by the invention]

[0005] In the process of implementing the embodiments of the present disclosure, it has been found that the related art has at least the following problems.

[0006] The layout of the fresh air duct and pipeline adopted in the related technology mainly has two types: (1) a type in which the same duct is shared, and (2) a type in which two ducts are separated. However, both of these types have certain drawbacks, such as the former resulting in a messy layout of the piping and a large intake area for the fresh air duct, and the latter resulting in problems such as the inconvenience of installing the pipeline and the difficulty of inserting the two ducts into the wall penetration hole. Therefore, there is a need to further optimize the layout style adopted in the related technology. [Means for solving the problem]

[0028] In the embodiments of the present disclosure, the symbol " / " indicates that the objects before and after it are in an "or" relationship, for example, A / B indicates A or B.

[0029] The term "and / or" describes an associative relationship between objects and means that a triple relationship can exist, for example, A and / or B represents a triple relationship with A or B, or A and B.

[0030] In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other without conflict.

[0031] As shown in FIGS. 1 and 2 , in some optional embodiments, the wall penetration pipe assembly includes components such as an outside air duct 100, a wire harness pipe 200, and an outside air inner connecting pipe set, where the outside air duct 100 and the wire harness pipe 200 are pipe segments that penetrate the wall, and the outside air inner connecting pipe set is a pipe segment that connects the outside air duct 100 on the indoor side with an outside air device (e.g., an air conditioner).

[0032] In some embodiments, as shown in FIG. 3, the outside air duct 100 is a long, straight pipe, and inside it is formed an outside air duct cavity that is molded to extend along the pipe's longitudinal direction and is open at both ends. The outside air duct cavity functions as a passage through which outside air flows through the outside air duct 100. When the outside air duct 100 is attached to a wall through-hole provided in the wall of a building, one end of the outside air duct 100 is located outside the wall and serves as the intake end of the outside air duct 100, and the other end of the outside air duct 100 is located inside the wall (i.e., inside the room) and serves as the exhaust end of the outside air duct 100. The outside air flows from the intake end of the outside air duct 100 through the outside air duct cavity to the exhaust end.

[0033] In the embodiment, both the inner wall surface and the outer wall surface of the outside air duct 100 are configured as smooth surfaces. Here, the outer wall surface of the outside air duct 100 is the surface that comes into contact with the wall through-hole and the wire harness tube 200, and by making the outer wall surface a smooth surface, the frictional force with the wall through-hole and the contact surface with the wire harness tube 200 when installing the outside air duct 100 can be reduced, and the effort required to quickly insert the outside air duct 100 into the wall through-hole can be further reduced. Furthermore, the inner wall surface of the outside air duct 100 is the surface that comes into contact with air, and by making the inner wall surface a smooth surface, the effect of resistance that the outside air duct cavity has on the airflow can be reduced, and the intake volume and intake wind speed can be improved.

[0034] In another embodiment, the outdoor air duct 100 not only introduces fresh outdoor air into the room, but also functions as an "exhaust duct" that can discharge dirty indoor air into the outdoor environment. In this state, the order in which air passes through the outdoor air duct 100 is from the exhaust end (indoor side) of the outdoor air duct 100 through the outdoor air duct cavity toward the intake end (outdoor side).

[0035] Alternatively, the outside air duct 100 may be made of a metal material, a non-metal material, or a composite material, such as a commonly used metal material such as galvanized steel, stainless steel, or aluminum, or a commonly used non-metal material such as rigid polyvinyl chloride, glass fiber reinforced plastic, etc. The embodiments of the present disclosure are not limited to the selection of the material for the outside air duct 100.

[0036] Alternatively, the thickness of the pipe wall of the outside air duct 100 may be in the range of 0.3 cm to 1 cm. Here, the pipe wall dimensions of the outside air duct 100 can be adaptively adjusted according to factors such as the design ventilation volume of the outside air duct 100, the dimensions of the wall through-hole, the type of pipe material, etc., so as to satisfy the design requirements for ventilation and pressure when attached to a wall through-hole and to ensure the durability of the outside air duct 100.

[0037] Alternatively, the length of the outside air duct 100 may be in the range of 30 cm to 40 mm. The length of the outside air duct 100 may be extended or shortened as needed depending on the wall thickness of the building, and the present application is not particularly limited to this length.

[0038] In some embodiments, as shown in FIG. 4 , the wire harness pipe 200 is a long, straight pipe. The wire harness pipe 200 is installed in close contact with the outside air duct 100 in the same direction so as to penetrate through the same wall through-hole. The longitudinal direction of the wire harness pipe 200 and the outside air duct 100 is the drilling direction of the wall through-hole. Inside the outside air duct 100, a wire harness pipe cavity is formed extending in the longitudinal direction of the outside air duct 100, with both ends open. The wire harness pipe cavity functions as a space to accommodate a group of wire harnesses of an air conditioner, so that the group of wire harnesses can connect indoor and outdoor units of an outside air device, for example, so that the group of wire harnesses can connect the outdoor unit and indoor unit of an air conditioner. When the wire harness pipe 200 is installed in a wall through-hole provided in a wall of a building, one end of the wire harness pipe 200 is located outside the wall and the other end is located inside the wall (i.e., on the indoor side).

[0039] Optionally, the types of wire harnesses in the wire harness group include, but are not limited to, refrigerant piping, signal lines, power supply lines, condensation water pipes, etc. One or more of the above types of wire harnesses can be accommodated in the wire harness pipe cavity of the wire harness pipe 200. The multiple types of wire harnesses may be bundled and then placed in the wire harness pipe cavity, or may be directly placed in the wire harness pipe cavity while being spaced apart from each other.

[0040] In the embodiment, the outside air duct 100 and the wire harness pipe 200 are installed in close contact with each other through surface contact, so that the contact area between the outside air duct 100 and the wire harness pipe 200 can be increased, and the positional deviation between the outside air duct 100 and the wire harness pipe 200 after installation can be reduced, and the outside air duct 100 and the wire harness pipe 200 can be positioned relative to each other to ensure a good fit.

[0041] Alternatively, the contact surface between the outside air duct 100 and the wire harness pipe 200 may be a regular or irregular curved surface, such as an arcuate surface, a wavy surface, or a toothed surface. By matching the shapes of the contact surfaces of the outside air duct 100 and the wire harness pipe 200, the two can be fitted together more closely and gaps at the contact surfaces can be reduced, thereby also serving as a windproof and dustproof surface.

[0042] In some embodiments, the wire harness tube 200 can be manufactured using a metallic material, a non-metallic material, or a composite material, such as a commonly used metallic material such as galvanized steel, stainless steel, or aluminum, or a commonly used non-metallic material such as rigid polyvinyl chloride, fiberglass reinforced plastic, etc. Embodiments of the present disclosure are not limited to the material of the wire harness tube 200.

[0043] Alternatively, the wire harness pipe 200 and the fresh air pipe 100 may be made of the same material, for example, rigid polyvinyl chloride, thereby reducing the number of process equipments and reducing manufacturing costs.

[0044] In some embodiments, the thickness of the pipe wall of the wire harness pipe 200 can be in the range of 0.3 cm to 1 cm. Here, the pipe wall dimensions of the wire harness pipe 200 can be adaptively adjusted depending on factors such as the dimensions of the wall through-hole and the type of pipe material so as to satisfy design requirements for pressure when attached to the wall through-hole and ensure durability of the wire harness pipe 200.

[0045] Optionally, the wire harness pipe 200 and the external air pipe 100 have the same pipe wall thickness.

[0046] In some embodiments, the length of the wire harness pipe 200 can be in the range of 30 cm to 40 mm. Here, the length of the wire harness pipe 200 can be appropriately extended or shortened depending on the wall thickness of the building, and the present application is not particularly limited to the length.

[0047] Optionally, the wire harness pipe 200 and the outside air pipe 100 have the same pipe length.

[0048] Conventional wire harness routing methods, which use pipes with completely closed outer contours, can only be inserted from one end and exited from the other end. However, since the material used for wire harnesses is soft, the wire harness tends to get stuck inside the pipe during routing, making it inconvenient to route the wire harness.

[0049] In contrast to this, in an embodiment of the present disclosure, mounting notches 230 are formed in the wall of wire harness tube 200, extending along the tube longitudinal direction, and extending to both ends of wire harness tube 200, and are provided so as to penetrate the wall of wire harness tube 200 in the thickness direction of wire harness tube 200. In this embodiment, mounting notches 230 are equivalent to openings on the outer peripheral contour line of wire harness tube 200, so that the outer peripheral contour line of wire harness tube 200 has a semi-closed structure, and a long wire harness can be directly inserted into the wire harness tube cavity by transverse feeding from the outside through mounting notches 230, which makes handling easy and does not cause the problem of wire harness accumulation.

[0050] Furthermore, as shown in FIG. 5 , in order to prevent the wire harness from slipping out of the wire harness pipe cavity after the wire harness pipe 200 is attached to the wall through-hole, in this embodiment, the attachment notch 230 of the wire harness pipe 200 is provided on the contact surface. Therefore, when the wire harness pipe 200 and the outside air duct 100 are installed in parallel and in close contact with each other, the contact surface of the outside air duct 100 acts as an actual plate surface and directly closes the attachment notch 230, so that the wire harness pipe cavity has a completely closed outer periphery, thereby confining the wire harness pipe 200 within the wire harness pipe cavity.

[0051] 4 , the wire harness pipe 200 includes an outer pipe wall portion 210 and two folded edge portions 220 formed to extend oppositely from both side edges of the outer pipe wall along the contact surface, and a gap between the two folded edge portions 220 forms an attachment notch 230. In the embodiment, the outer pipe wall portion 210 mainly functions as a pipe wall portion that fits into the through-wall hole, and the two folded edge portions 220 and the attachment notch 230 commonly form the contact surface of the wire harness pipe 200.

[0052] In the embodiments, for a planar contact surface, the term "opposite extension" means that the two edge folds 220 are extended close to each other on the same plane, whereas for a non-planar contact surface, the term "opposite extension" means that the two edge folds 220 are extended close to each other, and the extension line shape of each edge fold 220 may be a regular or irregular curve, a broken line, etc. In this embodiment, the outer pipe wall portion 210 of the wire harness pipe 200 and the two folded edge portions 220 are integrally molded to have an integral structure.

[0053] Generally, the hole shape of the wall through-hole is circular, so that the wall through-hole assembly fits snugly into the wall through-hole, and therefore the cross section of the entire wall through-hole pipe segment formed by the fresh air duct 100 and the wire harness pipe 200 being tightly fitted together has a circular shape. Optionally, the cross section of the fresh air duct 100 has a closed arc shape, and the cross section of the wire harness pipe 200 has a semi-closed arc shape, and the sum of the radians of the arc on which the fresh air duct 100 is located and the arc on which the wire harness pipe 200 is located is 2π, thereby ensuring that the cross section of the fresh air duct 100 and the wire harness pipe 200 being tightly fitted together has a perfect circle shape.

[0054] For example, the radian of the arc on which the outside air duct 100 is located is 3π / 2, and correspondingly, the radian of the arc on which the wire harness 200 is located is π / 2. The cross-sectional area of ​​the outside air duct 100 is larger than the cross-sectional area of ​​the wire harness 200 in proportion to this radian, so that this is suitable when a large amount of outside air is needed or when there are a small number of wire harnesses 200 and the pipe diameter is small. Alternatively, the radian of the arc on which the outside air duct 100 is located is 2π / 3, and correspondingly, the radian of the arc on which the wire harness pipe 200 is located is 4π / 3. The cross-sectional area of ​​the outside air duct 100 is smaller than the cross-sectional area of ​​the wire harness pipe 200 in proportion to this radian, so that this is suitable when a small amount of outside air is needed or when there are a large number of wire harness pipes 200 and the pipe diameter is large.

[0055] 5, when the cross section of the outside air duct 100 is semicircular and the cross section of the wire harness pipe 200 is also semicircular, the radian of the arc on which the outside air duct 100 and the wire harness pipe 200 are located is π. In this embodiment, the contact surface of the outside air duct 100 is set to a plane on which its diameter line is located, and the contact surface of the wire harness pipe 200 is set to a plane on which the same diameter line is located, and the two folded edge portions 220 of the wire harness pipe 200 are formed to extend radially from the outer periphery toward the center of the circle.

[0056] In another embodiment not shown, when the hole shape of the wall-penetrating hole is a non-circular hole such as a square or ellipse, the outer peripheral contour of the entire wall-penetrating pipe segment formed by the outside air duct 100 and the wire harness pipe 200 being tightly fitted also matches the hole shape of the wall-penetrating hole, thereby reducing the gap between the wall-penetrating pipe segment and the wall-penetrating hole, and reducing the impact of air flow, dust, etc. entering the indoor side through the gap when the two are fitted together, which would have an adverse effect on the cleanliness of the indoor environment.

[0057] According to the wall-penetrating pipe assembly provided in the embodiment of the present disclosure, two pipe components, the outside air duct 100 and the wire harness pipe 200, are used to separate the wire harness group from the outside air passage, thereby avoiding mutual interference between the two. In addition, the wire harness group is attached via an attachment notch 230 opened in the wire harness pipe 200, and this attachment notch 230 is closed by the outside air duct 100, so the structure is simple and the installation work is quick and easy.

[0058] In some optional embodiments, the wall penetration pipe assembly further includes a hood 300 removably mounted on the intake end of the fresh air duct 100, which can serve to filter fresh air and provide protection from wind, rain, or debris.

[0059] As shown in FIGS. 6 and 6A, the hood 300 includes a hood body 310 and a grill 320.

[0060] Here, hood body 310 is configured as a barrel shaped to extend outward in the same direction as outside air duct 100, with one outward end of hood body 310 closed and one inward end sleeve-connected to the intake end of outside air duct 100. In the illustration, outside air duct 100 is a tubular body with a semicircular cross section, so hood body 310 is also configured as a cylindrical body with a semicircular cross section. The pipe diameter of one inward end of the cylindrical body is slightly smaller than the pipe diameter of the intake end of outside air duct 100, so that one inward end of the cylindrical body is inserted into the intake end of outside air duct 100 to achieve a sleeve connection between the two.

[0061] In the embodiment, one or more outwardly facing convex portions 311 are provided on the outer wall of one inward end of hood body 310, and correspondingly, one or more inwardly concave grooves 101 are provided on the inner wall of the intake end of fresh air duct 100. After hood body 310 is inserted into fresh air duct 100, each convex portion engages with groove 101 in a one-to-one correspondence, thereby forming a stopper in the longitudinal direction of fresh air duct 100, making it difficult for hood 300 to slip out in the opposite direction after being attached to fresh air duct 100 and fulfilling the role of locking and positioning. In Fig. 3, there are two grooves 101, which are provided on the contact surface of fresh air duct 100. Correspondingly, in Fig. 6, there are two convex portions, which are provided on the diametric plane of hood body 310, which has a semicircular cross section.

[0062] In this embodiment, an outside air intake port is provided on the downward-facing side surface of hood body 310, and the outside air intake port is provided facing downward to prevent rainwater falling from above from entering hood body 310. The outside air intake port is a rectangular opening provided on the diameter plane of hood body 310, and outside air can enter hood body 310 through this opening and then flow into outside air duct 100.

[0063] Grill 320 is installed to cover the outside air intake port, and functions to filter the flow of air coming in. As shown in Figure 6, grill 320 is made up of multiple grids arranged in parallel with intervals, with bar-shaped air holes formed between adjacent grids.

[0064] In some optional embodiments, the through-wall pipe assembly further includes an outside air inner connecting pipe set that can be used to connect the outside air duct 100 and an outside air device (e.g., an air conditioner, etc.). Generally, the intake area of ​​the intake port of the outside air device is larger than the intake area of ​​the outside air duct 100. Therefore, in order to facilitate the connection between the outside air duct 100 and the outside air device having different intake areas, as shown in Figures 1 and 2, the outside air inner connecting pipe set includes a transition connecting pipe 400, which is a pipe segment with a changing cross-sectional area, and an intermediate connecting pipe 500, which is an extended pipe segment.

[0065] As shown in Figures 7 and 7A, the first transition end 410 of the transition connecting pipe 400 is connected to the exhaust end of the fresh air duct 100, and the second transition end 420 is connected to the intermediate connecting pipe 500. Here, the shape of the first transition end 410 is adapted to the shape of the exhaust end of the fresh air duct 100. For example, if the cross section of the exhaust end of the fresh air duct 100 in the above embodiment is semicircular, the cross section of the first transition end 410 will also be semicircular, and the first transition end 410 and the exhaust end of the fresh air duct 100 will be sleeve-connected, and the first transition end 410 and the exhaust end of the fresh air duct 100 will be sleeve-connected, and the cross section of the second transition end 420 will be circular, and the ventilation area of ​​the second transition end 420 will be larger than the ventilation area of ​​the first transition end 410.

[0066] The pipe segment of the transition connector pipe 400 between the first transition end 410 and the second transition end 420 has a gradually expanding cross-sectional area, with a curved or straight transition slope 430 forming the transition therebetween.

[0067] Optionally, the length of the transition connector 400 ranges from 20 cm to 30 cm.

[0068] 8, the intermediate connecting pipe 500 is a circular pipe, and both ends thereof are connected to the second transition end 420 and the fresh air device, respectively. Optionally, the intermediate connecting pipe 500 and the second transition end 420 are threadedly coupled, and / or the intermediate connecting pipe 500 and the air inlet of the fresh air device are threadedly coupled.

[0069] Alternatively, the length of the intermediate connecting pipe 500 ranges from 120 cm to 160 cm.

[0070] Alternatively, the intermediate connecting pipe 500 can be constructed by sequentially connecting multiple segments of pipe, so that by dividing the intermediate connecting pipe 500 into multiple short segments, the processing and transportation of the pipe segments can be made easier, and the intermediate connecting pipe 500 can be made longer or shorter by increasing or decreasing the number of pipe segments, so that it can accommodate differences in installation due to different air duct lengths in the user's room.

[0071] Optionally, the transition connecting pipe 400 and / or the intermediate connecting pipe 500 are corrugated hoses with good axial ductility and radial elasticity, which can well meet the connection requirements between the fresh air device and the fresh air duct 100.

[0072] In some optional embodiments, the outside air inner connecting pipe set also includes an outer joint 600, which is provided at one end of the intermediate connecting pipe 500 that connects to the outside air device. As shown in Fig. 9, the outer joint 600 has an L-shaped elbow structure, one end of which is connected to the intermediate connecting pipe 500 and the other end of which is connected to the outside air device. The L-shaped elbow can serve to change and reinforce the air flow, allowing the air to flow more smoothly into the outside air device, and the connection strength at the pipe connection position is high.

[0073] In some optional embodiments, the wall penetration pipe assembly further includes a packaging member that bundles and connects the wire harness group and the transition connection pipe 400, and by providing the packaging member, clutter can be prevented from occurring at the portion of the wire harness group extending toward the interior of the room, and the appearance can be improved by keeping the area neat and tidy.

[0074] Alternatively, the packing material may be nylon rope, tape, or the like.
