Description

Technical Field

[0001] This invention relates to the field of central air conditioning duct technology, and in particular to a suspended concealed flexible composite duct system. Background Technology

[0002] Existing flexible composite duct systems require a suspension mechanism sewn onto the surface of the duct. For example, patent application CN201821684858.4 proposes an externally supported flexible duct system, which includes a duct body; at least two suspension members arranged along the length of the duct body and respectively connected to both ends of the duct body's cross-section; and support members spaced apart from the duct body. These support members are rigid and their ends are fixed to the suspension members at both ends of the duct body's cross-section. The support members support the duct body, and the duct body can be hoisted using hooks or steel ropes. This results in more even stress distribution on the duct body, better flatness after installation, and convenient overall hoisting and disassembly, making it highly adaptable.

[0003] However, the suspension structure of the above-mentioned duct system has the following problems: 1. The suspension mechanism protrudes from the surface of the duct, affecting the overall flatness and aesthetics of the duct.

[0004] 2. The number and position of the suspension mechanism are fixed, and the number and position of the suspension rows cannot be flexibly adjusted during later installation and use, resulting in poor versatility of the duct.

[0005] 3. During the sewing process, the stitching thread penetrates the insulation layer of the air duct, resulting in air leakage and condensation at the stitching point.

[0006] 4. The low sewing efficiency of the suspension mechanism affects the production capacity of air ducts. Summary of the Invention

[0007] In view of this, it is necessary to provide a suspended concealed flexible composite duct system to solve the above problems.

[0008] This invention provides a suspended concealed flexible composite duct system, including a duct body, an outer protective layer, and a grooved interlayer. The outer protective layer wraps around the duct body and is fixedly connected to it. The grooved interlayer wraps around the outer protective layer, and there are multiple linear connection portions between the grooved interlayer and the outer protective layer. The multiple linear connection portions are evenly arranged along the circumference of the grooved interlayer. The portion of the grooved interlayer located between any two adjacent linear connection portions can form a through groove with the outer protective layer for a suspension member to pass through.

[0009] Furthermore, the linear connecting part is a stitch, and multiple stitches connect the fabric groove interlayer and the outer protective layer. The portion of the fabric groove interlayer located between any two adjacent stitches forms a through groove with the outer protective layer.

[0010] Furthermore, the seam does not pass through the duct body.

[0011] Furthermore, the grooved interlayer is flexible, and the portion located between any two adjacent linear connecting parts has a first state and a second state. When the grooved interlayer is in the first state, it is tightly attached to the outer protective layer. When the grooved interlayer is in the second state, it bulges away from the outer protective layer to form a through groove through which the suspension member passes.

[0012] Furthermore, the length of the grooved interlayer is less than the length of the outer protective layer, the width of the grooved interlayer is the same as the width of the outer protective layer, and the middle position of the grooved interlayer is directly opposite the middle position of the outer protective layer.

[0013] Furthermore, the duct body includes an inner duct layer and an insulation layer arranged sequentially from the inside to the outside, and the outer protective layer and the insulation layer are integrally connected by a composite structure.

[0014] Furthermore, it also includes a first connecting zipper arranged at both ends of the circumferential direction of the duct body, and two adjacent duct bodies are connected via the first connecting zipper.

[0015] Furthermore, the outer wall of the duct body is provided with a notch along its length, and a second connecting zipper is provided at the notch of the duct body. When the male and female chains of the second connecting zipper are connected, the duct body is cylindrical. When the male and female chains of the second connecting zipper are separated, the duct body can be laid flat as a sheet.

[0016] Furthermore, the outer protective layer and the plurality of the grooved interlayers are all fiber fabric layers.

[0017] Furthermore, the suspension component includes a suspension slide rod, which is disposed through any of the through slots between the outer protective layer and the fabric groove interlayer.

[0018] Compared with existing technologies, 1. The ductwork interlayer wraps around the entire outer protective layer, resulting in a smooth and aesthetically pleasing overall appearance of the duct system, and effectively concealing the hanging components; 2. Multiple through slots are formed between the duct interlayer and the outer protective layer, evenly arranged along the circumference of the duct body. Multiple hanging parts can be set and installed in any through slot. In actual installation, the number and installation position of hanging parts can be flexibly adjusted, which improves the versatility of the duct. 3. With the addition of an outer protective layer, the ductwork interlayer can be installed on the outer protective layer, effectively avoiding the impact of the ductwork interlayer on the structure of the duct itself during installation. 4. The outer protective layer and the fabric interlayer can be pre-connected in the factory before assembly with the duct body, which improves the production efficiency of the duct system.

[0019] Figure 1 This is a schematic diagram of the overall structure of the suspended concealed flexible composite duct system provided in an embodiment of the present invention; Figure 2 for Figure 1 A schematic diagram showing the setup of the first and second connecting zippers. Detailed Implementation

[0020] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0021] like Figure 1 As shown in the figure, an embodiment of the present invention provides a suspended concealed flexible composite duct system, including a duct body 100, an outer protective layer 200, and a grooved interlayer 300; the outer protective layer 200 is disposed around the duct body 100 and fixedly connected to the duct body 100; the grooved interlayer 300 is disposed around the outer protective layer 200, and there are multiple linear connection parts between the grooved interlayer 300 and the outer protective layer 200. The multiple linear connection parts are evenly arranged along the circumference of the grooved interlayer 300, and the portion of the grooved interlayer 300 located between any two adjacent linear connection parts can form a through groove between it and the outer protective layer 200 for the suspension member 400 to pass through.

[0022] During implementation, the grooved interlayer 300 completely encloses the outer protective layer 200, resulting in a smooth and aesthetically pleasing overall appearance of the duct system, effectively concealing the hanging components 400. Multiple through-grooves are evenly distributed around the duct body 100 between the grooved interlayer 300 and the outer protective layer 200. Multiple hanging components 400 can be installed in any of these through-grooves, allowing for flexible adjustment of the number and position of the hanging components 400 during installation, thus improving the duct's versatility. The grooved interlayer 300 can be installed onto the outer protective layer 200, effectively preventing any impact on the duct body 100's structure during installation. The outer protective layer 200 and the grooved interlayer 300 can be pre-connected in the factory before assembly with the duct body 100, improving the duct system's production efficiency.

[0023] In this embodiment, the duct body 100 is a composite flexible duct.

[0024] In one embodiment, the duct body 100 includes an inner duct layer 110 and an insulation layer 120 arranged sequentially from the inside to the outside, and the outer protective layer 200 and the insulation layer 120 are integrally connected by a composite connection. The inner duct layer 110 is the inner lining of the duct body 100, and the insulation layer 120 is disposed on the outside of the inner duct layer 110 to isolate the inner duct layer 110 from the outside environment for heat exchange.

[0025] Of course, in other preferred embodiments, the duct body 100 may also include other forms of composite layers, such as anti-corrosion layers, etc., and there is no limitation thereto.

[0026] During installation, the aforementioned duct body 100 typically needs to be suspended at a certain height. Specifically, a suspension member 400 is used to connect the duct body 100, allowing it to be suspended within the factory or office space, freeing up floor space. To facilitate the connection between the duct body 100 and the suspension member 400, this application utilizes an outer protective layer 200 and a fabric groove interlayer 300, which will be described in detail below.

[0027] In this embodiment, the outer protective layer 200 is provided to wrap around the duct body 100 and is fixedly connected to the duct body 100. It not only has the function of protecting the duct body 100, but also serves to replace the duct body 100 in connection with the fabric groove interlayer 300.

[0028] In this embodiment, the groove interlayer 300 is provided to wrap the outer protective layer 200. There are multiple linear connection parts between the groove interlayer 300 and the outer protective layer 200. The multiple linear connection parts are evenly arranged around the circumference of the groove interlayer 300. The part of the groove interlayer 300 located between any two adjacent linear connection parts can form a through groove between it and the outer protective layer 200 for the suspension member 400 to pass through.

[0029] To achieve the connection between the groove interlayer 300 and the outer protective layer 200, in one embodiment, the linear connection part is a stitch 330. Multiple stitches 330 connect the groove interlayer 300 and the outer protective layer 200. The part of the groove interlayer 300 between any two adjacent stitches 330 forms a through groove with the outer protective layer 200.

[0030] Of course, in other preferred embodiments, the linear connection can also adopt other forms of structure such as Velcro or strip buckle, without limitation, with the preference for a stable connection. It is understood that the above solution is only suitable for duct systems with lighter weight. For duct systems with heavier weight, the linear connection mainly uses 330 stitching.

[0031] It should be noted that the seam 330 does not penetrate the duct body 100. This is to prevent the seam 330 from penetrating the insulation layer 120 of the duct body 100, which could lead to air leakage and condensation at the seam 330.

[0032] In one embodiment, the multiple through-slots formed between the fabric interlayer 300, the outer protective layer 200, and the multiple seams 330 are all arranged along the extension direction of the duct body. Of course, depending on the direction of the seams 330, non-linear through-slots can be formed. Therefore, the direction of the seams 330 is not limited to being linear and should be determined according to actual needs.

[0033] In one embodiment, the groove interlayer 300 is flexible, and the portion located between any two adjacent linear connecting parts has a first state and a second state. When the groove interlayer 300 is in the first state, the groove interlayer 300 is disposed close to the outer protective layer 200. When the groove interlayer 300 is in the second state, the groove interlayer 300 bulges away from the outer protective layer 200 to form a through groove through which the suspension member 400 passes.

[0034] When the hanging member 400 is not attached to the fabric groove interlayer 300 (i.e., when the fabric groove interlayer 300 is in the first state), the fabric groove interlayer 300 is tightly attached to the outer protective layer 200. At this time, the entire fabric groove interlayer 300 has good flatness and high aesthetics.

[0035] The grooved interlayer 300 only bulges slightly when the suspension member 400 passes through it, ensuring a certain degree of flatness in appearance. At the same time, since the grooved interlayer 300 has a large arrangement area and covers the suspension member 400, it can effectively hide the suspension member 400.

[0036] like Figure 2 As shown, in one embodiment, the length of the groove interlayer 300 is less than the length of the outer protective layer 200, the width of the groove interlayer 300 is the same as the width of the outer protective layer 200, and the middle position of the groove interlayer 300 is directly opposite the middle position of the outer protective layer 200. This ensures that the ends of the suspension member 400 that pass through the first opening 310 and the second opening 320 at both ends of the through groove are located on the outer protective layer 200, avoiding interference between it and the connection point of the adjacent duct body 100.

[0037] like Figure 2 As shown, in one embodiment, a first connecting zipper 210 is also arranged at both ends of the circumferential direction of the duct body 100, and two adjacent duct bodies 100 are connected via the first connecting zipper 210.

[0038] like Figure 2As shown, in one embodiment, the outer wall of the duct body 100 has a notch along its length. A second connecting zipper 220 is provided at the notch of the duct body 100. When the male and female chains of the second connecting zipper 220 are connected, the duct body 100 is cylindrical. When the male and female chains of the second connecting zipper 220 are separated, the duct body 100 can be laid flat as a sheet. With the above configuration, the sheet-like duct body 100 is easy to transport and store. In use, the forming process of the duct body 100 can be completed by connecting the male and female chains of the second connecting zipper 220.

[0039] It is understandable that the aforementioned duct body 100 can be selected in shapes such as circular or rectangular.

[0040] In one embodiment, the outer protective layer 200 and the plurality of fabric interlayers 300 are both fiber fabric layers.

[0041] In this embodiment, the suspension member 400 includes a suspension slide rod, which is disposed through any through groove between the outer protective layer 200 and the fabric groove interlayer 300. The suspension slide rod can pass through any through groove for suspension, and the number or position of the suspension slide rods can be one or more, and both can be adjusted arbitrarily.

[0042] In other preferred embodiments, the suspension member 400 may also be other forms of connectors such as ropes, and there is no limitation thereto.

[0043] Compared with existing technologies: 1. The 300mm interlayer wraps around the entire outer protective layer 200mm, resulting in a smooth and aesthetically pleasing overall appearance of the duct system, and effectively concealing the hanging components 400mm. 2. Multiple through slots are formed between the grooving interlayer 300 and the outer protective layer 200, which are evenly arranged around the circumference of the duct body 100. Multiple hanging parts 400 can be set and installed in any through slot. In actual installation, the number and installation position of the hanging parts 400 can be flexibly adjusted, which improves the versatility of the duct. 3. By using the outer protective layer 200, the groove interlayer 300 can be installed on the outer protective layer 200, effectively avoiding the impact of the groove interlayer 300 on the structure of the duct body 100 during the installation process; 4. The outer protective layer 200 and the fabric interlayer 300 can be pre-connected in the factory before assembly with the duct body 100, which improves the production efficiency of the duct system.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
