Description

Technical Field

[0001] This utility model relates to the field of central air conditioning duct technology, specifically a modular central air conditioning duct assembly. Background Technology

[0002] Central air conditioning ducts are connected to the central air conditioning unit and can deliver hot or cold air to different indoor spaces. Commonly used ducts are rectangular pipes made of stainless steel. Long-distance ducts require the assembly of multiple modular ducts. During assembly, the corners of two adjacent ducts are usually locked with bolts. The ducts are also equipped with mesh panels inside, which can block dust, hair, dander and other small particles in the outside air from entering the air conditioning system, ensuring the normal operation of the air conditioning system and the cleanliness of the indoor environment.

[0003] When installing bolts between two ducts, the user needs to support the duct first and then insert the bolts into the bolt holes between the two ducts. Most ducts lack components for positioning and supporting the duct, which makes it difficult for users to install the ducts conveniently. In addition, the mesh panels inside the ducts usually need to be removed from the duct for cleaning, which is not conducive to washing the inside of the duct with water. Utility Model Content

[0004] The purpose of this invention is to provide a modular central air conditioning duct assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A modular central air conditioning duct assembly, comprising:

[0007] A rectangular duct, wherein two positioning posts are fixed at one end of the rectangular duct, and two rectangular holes are opened through the bottom of the rectangular duct;

[0008] There are two fixed columns, each fixed inside the rectangular duct at the end away from the positioning column. The positioning column has a sliding positioning shaft inside, which is movably connected to the positioning column.

[0009] A rectangular frame is rotatably connected inside a rectangular air duct, and a mesh plate is fixed inside the rectangular frame.

[0010] Support block one is slidably engaged with rectangular hole one at the corresponding position, and a water spray pipe is fixed to the top of support block one;

[0011] Support block two is slidably engaged with rectangular hole one at the corresponding position. A rectangular cavity is opened inside support block two, and a rectangular hole three communicating with the rectangular cavity is opened on one side of support block two.

[0012] Furthermore, the bottom of the support block is fixed with a water inlet pipe that is connected and fixed to the water spray pipe, and multiple nozzles are installed at equal intervals on the outer side of the water spray pipe.

[0013] Furthermore, the bottom of the second support block is fixed with a drain pipe that communicates with the rectangular cavity, and a valve is installed inside the drain pipe.

[0014] Furthermore, one end of the fixed post is provided with a circular hole 2 that is slidably connected to the positioning shaft, a toggle block is fixed on the outside of the positioning shaft, and a rectangular hole 2 that is slidably connected to the toggle block is provided on the outside of the fixed post.

[0015] Furthermore, the inner bottom of the rectangular duct is fixed with a protruding post, and both sides of one end of the rectangular duct are provided with sliding grooves, and the actuating block is slidably connected to the sliding grooves.

[0016] Furthermore, the bottom of both ends of the rectangular frame is fixed with a rotating shaft, the rotating shaft is rotatably connected to the rectangular air duct, a connecting rod is fixed to one end of the rotating shaft that passes through the rectangular air duct, and a bolt is detachably screwed between the connecting rod and the rectangular air duct.

[0017] Furthermore, the rectangular duct has positioning holes and rotating holes on both sides. The positioning holes are screwed into the bolts, and the rotating holes are rotatably connected to the rotating shaft.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Two positioning posts are fixed at one end of the rectangular duct, and the positioning posts have a circular hole 1 inside. Two fixing posts are fixed at the other end of the rectangular duct, and a positioning shaft is slidably engaged inside the fixing posts. When it is necessary to assemble one rectangular duct into the opening of another rectangular duct that has been fixed on the roof, the positioning shaft is pushed by the toggle block to slide out from the inside of the fixing post and insert into the circular hole 1. This allows the positioning shaft to pre-support and position the rectangular duct to be assembled into the opening of an installed rectangular duct, eliminating the need for manual support of the rectangular duct to be installed and freeing up the user's hands to use bolt 2 to lock and fix the two rectangular ducts.

[0020] 2. By rotating the connecting rod, the mesh plate is rotated to the inner bottom of the rectangular duct. Then, support block one and support block two are pushed into the rectangular duct, so that the mesh plate is placed between support block one and support block two. External water is supplied to the spray pipe through the water inlet pipe, and then sprayed onto the mesh plate from multiple nozzles on the spray pipe to achieve water rinsing of the mesh plate. During the rinsing process, the mesh plate can be tilted at different angles in front of multiple nozzles by moving the connecting rod, so that multiple nozzles can spray water onto different areas of the mesh plate, facilitating all-round rinsing of the mesh plate. Support block two blocks one end of the mesh plate to prevent sewage from flowing along the rectangular duct. Opening the drain valve on support block two allows the drain pipe to discharge the sewage used to clean the mesh plate into the rectangular duct, thereby realizing automatic water washing of the mesh plate inside the rectangular duct, which helps to improve the cleaning efficiency of the mesh plate.

[0021] 3. By rotating the mesh panel to the bottom of the rectangular duct and closing the valve inside the drain pipe, the water spray pipe continues to deliver water or cleaning fluid into the space between support block one and support block two. This allows the mesh panel to be immersed in the cleaning tank surrounded by support block one, support block two and the rectangular duct, which facilitates thorough immersion and cleaning of the mesh panel and improves the water washing effect of the mesh panel.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1, please refer to Figure 1 - Figure 6 In this embodiment of the utility model, a modular central air conditioning duct assembly includes a rectangular duct 100. Positioning posts 110 are fixed at two corners of the top inner end of one end of the rectangular duct 100, and fixing posts 200 are fixed at two corners of the top inner end of the other end of the rectangular duct 100. A positioning shaft 210 slides inside the fixing post 200, and the positioning shaft 210 is movably inserted into the corresponding positioning post 110. A rectangular frame 300 is rotatably connected inside the rectangular duct 100, and a mesh plate 310 is fixed inside the rectangular frame 300. Two rectangular holes 120 are opened through the bottom of the rectangular duct 100. A support block 400 and a support block 500 are slidably engaged inside the two rectangular holes 120, respectively. A water spray pipe 410 is fixed to the top of the support block 400. A rectangular chamber is opened inside the support block 500, and a rectangular hole 3 510 communicating with the rectangular chamber is opened on one side of the support block 500.

[0031] Specifically, a traditional duct (equivalent to the rectangular duct 100 of this application) has positioning posts 110 and fixing posts 200 fixed at both ends. When installing the two ducts by connecting their openings, the positioning shaft 210 inside the fixing post 200 can be slid inward towards the positioning post 110, thereby allowing the positioning shaft 210 to support and position the duct to be installed at the completed opening. This eliminates the need for manual support of the duct, improving installation efficiency. Support blocks 400 and 500 slide inside the rectangular duct 100, and the sliding of support blocks 400 and 500 simultaneously... Inside the rectangular duct 100, the water spray pipe 410 sprays water onto the mesh plate 310. By rotating the connecting rod 321, the rectangular frame 300, carrying the mesh plate 310, rotates and adjusts its position on the water spray side of the water spray pipe 410. This allows the water spray pipe 410 to automatically wash away dirt from the mesh plate 310. At the same time, the support block 500 seals one end of the mesh plate 310 to prevent wastewater from flowing inside the rectangular duct 100. This allows the cleaned wastewater to be discharged directionally from the rectangular duct 100 along the drain pipe 520, eliminating the need to remove the mesh plate 310 from inside the rectangular duct 100 for cleaning, thus improving the cleaning efficiency of the mesh plate 310.

[0032] like Figure 1 and Figure 5 As shown, in this embodiment, the bottom of the support block 400 is fixed with an inlet pipe 420 that is connected and fixed to the spray pipe 410. Multiple nozzles are installed at equal intervals on the outer side of the spray pipe 410. When rinsing the screen plate 310, the support block 400 moves the spray pipe 410 into the rectangular air duct 100. The external water pumping pipe delivers water to the inlet pipe 420. The water is sprayed onto the screen plate 310 through the multiple nozzles on the spray pipe 410, which facilitates the washing of the screen plate 310.

[0033] like Figure 4 and Figure 5 As shown, in this embodiment, the bottom of the support block 2 500 is fixed with a drain pipe 520 that communicates with the rectangular cavity. A valve is installed inside the drain pipe 520. When rinsing the mesh plate 310, the valve can be opened so that the dirty water used to clean the mesh plate 310 flows from the rectangular hole 3 510 into the rectangular cavity and then is discharged to the outside through the drain pipe 520.

[0034] like Figure 2 and Figure 3 As shown, in this embodiment, one end of the fixed column 200 is provided with a circular hole 220 that is slidably connected to the positioning shaft 210. A toggle block 211 is fixed on the outside of the positioning shaft 210. A rectangular hole 230 is provided on the outside of the fixed column 200 that is slidably connected to the toggle block 211. Both sides of one end of the rectangular air duct 100 are provided with a sliding groove 140. The toggle block 211 passes through the sliding groove 140 and is slidably connected to the sliding groove 140.

[0035] In this embodiment, when connecting the duct to be installed to the inlet of the installed duct, the inlets of the two ducts are first aligned, and then the moving block 211 is moved along the slide groove 140 to make the positioning shaft 210 slide out from the inside of the second round hole 220. The slid-out positioning shaft 210 is inserted into the inside of the first round hole 111 of the positioning post 110 of the installed duct, so that the positioning shaft 210 is positioned and inserted between the two ducts, playing the role of supporting and positioning the duct.

[0036] like Figure 4 As shown, in this embodiment, a protruding post 130 is fixed to the inner bottom of the rectangular duct 100. The protruding post 130 creates a gap between the mesh plate 310, which is rotatably placed on the inner bottom surface of the rectangular duct 100, and the inner bottom surface of the rectangular duct 100, so that sewage can flow through the mesh plate 310.

[0037] like Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, a rotating shaft 320 is fixed at the bottom of both ends of the rectangular frame 300. The rotating shaft 320 is rotatably connected to the rectangular air duct 100. A connecting rod 321 is fixed at one end of the rotating shaft 320 that passes through the rectangular air duct 100. A bolt 3211 is detachably screwed between the connecting rod 321 and the rectangular air duct 100. A positioning hole 150 and a rotating hole 160 are provided on both sides of the rectangular air duct 100. The positioning hole 150 is screwed to the bolt 3211, and the rotating hole 160 is rotatably connected to the rotating shaft 320.

[0038] In this embodiment, in the initial state, the mesh plate 310 is vertically arranged inside the rectangular duct 100. At this time, the connecting rod 321 is in a vertical state. By screwing the connecting rod 321 and the positioning hole 150 of the rectangular duct 100 together with the bolt 3211, the connecting rod 321 is fixed to the outside of the rectangular duct 100. This allows the connecting rod 321, along with the rectangular frame 300 and the mesh plate 310, to be vertically fixed inside the rectangular duct 100, thus intercepting dust and impurities inside the rectangular duct 100. When it is necessary to rotate the connecting rod 321 with the mesh plate 310, simply remove the bolt 3211 and then move the connecting rod 321 outside the rectangular duct 100 to adjust the position of the mesh plate 310.

[0039] like Figure 2 As shown, in this embodiment, both ends of the rectangular duct 100 are fixed with connecting frames 170. After the rectangular duct 100 is supported by the positioning shaft 210, the bolts are then inserted into the bolt holes of the two adjacent connecting frames 170 to install and fix the two rectangular ducts 100 using the bolts. The specific work of fixing the two rectangular ducts 100 with the bolts is a prior art solution and will not be described in detail here.

[0040] like Figure 5 and Figure 6 As shown, in this embodiment, both ends of the rectangular hole 120 are fixed with locking blocks, and both ends of the support block 400 and the support block 500 are provided with locking slots. The locking blocks slide in the locking slots so that the support block 400 and the support block 500 can slide in the rectangular hole 120 without detaching from the rectangular hole 120.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
