Description

Technical Field

[0001] This utility model belongs to the field of air duct machine air guiding technology, and specifically relates to an efficient air outlet air guiding structure for American-style air duct machines. Background Technology

[0002] The high-efficiency airflow structure of American-style ducted air conditioners achieves directional and efficient airflow through optimized vent design and centrifugal metal impeller configuration. This structure utilizes the precise connection between the vents on the impeller mounting plate and the centrifugal impeller outlet, combined with an advanced regulator, to ensure that air is evenly distributed to every corner of the room, while reducing energy consumption and improving overall air supply efficiency and comfort.

[0003] However, the existing American-style ducted air conditioning system still has some shortcomings. American-style ducted air conditioning systems are generally used in large event venues such as shopping malls. They are usually central ducted air conditioning systems. When blowing hot or cold air, the air is usually blown vertically into the mall from top to bottom. After blowing to a certain point, the hot or cold air will diffuse in all directions, resulting in low diffusion efficiency. It is common for passers-by to stand at the bottom of the air conditioning system to feel a strong wind, while the wind force around them is very weak, which is not efficient enough. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an efficient air outlet guiding structure for American-style duct air conditioners to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An efficient airflow guiding structure for an American-style ducted air conditioner includes a duct body with a protective frame snapped onto its bottom end. An air outlet is located at the bottom end of the protective frame. A first guide plate is installed on the inner wall of the air outlet. A connecting plate is threadedly connected to the bottom end of the duct body, located inside the protective frame. A rotating shaft is rotatably connected to the bottom end of the connecting plate. A rotating plate is fixedly connected to the bottom end of the rotating shaft. A second guide plate is fixedly connected to the outer wall of the rotating plate. The second guide plate is inclined, and a limit frame is fixedly connected to the outer side of the second guide plate. The position of the second guide plate corresponds to the position at the bottom end of the duct body. The rotating shaft is installed at the center of the bottom end of the connecting plate.

[0007] As a preferred technical solution, the bottom end of the connecting plate is provided with a screw hole, which extends into the interior of the air duct body. A bolt is threadedly connected to the inner side of the screw hole, and the top of the bolt is threadedly connected to the interior of the air duct body through the screw hole. The connecting plate is threadedly connected to the bottom end of the air duct body through the screw hole and the bolt.

[0008] As a preferred technical solution, a filter plate is installed on the inner wall of the duct body, the filter plate covers the inner side of the duct body, and the position of the filter plate corresponds to the position of the connecting plate.

[0009] As a preferred technical solution, a positioning groove is provided at the bottom of the air duct body. The positioning groove is located on the four sides near the corners of the bottom of the air duct body. A positioning block that matches the positioning groove is fixedly connected to the top of the protective frame. The positioning block is engaged with the inside of the positioning groove.

[0010] As a preferred technical solution, a sealing groove is provided at the bottom of the duct body, and a sealing ring that matches the sealing groove is fixedly connected to the top of the protective frame. The sealing ring is located on the inner side of the positioning block and covers the inner side of the sealing groove.

[0011] As a preferred technical solution, a mounting block is fixedly connected to the top of the protective frame. The other side of the mounting block is attached to the outer wall of the air duct body. A first slot is provided on one side of the mounting block. The first slot extends into the interior of the air duct body. A second slot is provided on the inner wall of the first slot. A circular groove is provided on the inner side of the first slot. A first locking block is engaged with the inner side of the first slot. A second locking block that matches the second slot is fixedly connected to the outer side of the first locking block. The second locking block is engaged with the inner side of the circular groove.

[0012] As a preferred technical solution, a retaining spring that matches the second retaining block is installed on the inner side of the circular groove. The other side of the second retaining block is engaged with one side of the retaining spring. The second retaining block is engaged with the inner side of the circular groove by the retaining spring. A sealing block is fixedly connected to one side of the first retaining block. The sealing block covers one side of the first retaining groove. A protrusion is fixedly connected to one side of the sealing block. The protrusion has an arc-shaped corner.

[0013] In summary, the present invention has the following main advantages:

[0014] First, during use, the operation of the duct unit can blow the air downwards. The airflow concentrated at the center point will be blown to the second guide plate. Because the second guide plate is inclined, it will generate a certain amount of wind force to push it. Its rotating shaft can make the rotating plate rotate, thereby driving the second guide plate to rotate, which can diffuse the air at the center point to the surroundings, and then discharge it through the first guide plate. This allows the air discharged through the first guide plate to diffuse to the surroundings as soon as possible, which can effectively improve the efficiency of airflow guidance.

[0015] Secondly, the presence of the first locking block facilitates the insertion of the second locking block into the circular slot. By adjusting the second locking block to a position that does not correspond to the second slot, the protective frame can be effectively engaged to prevent displacement. When the protective frame structure needs to be disassembled for maintenance, the second locking block can be adjusted to a position corresponding to the second slot, allowing the first locking block to be pulled out directly. Then, the positioning block can be pulled out of the positioning slot, thus facilitating the disassembly and assembly of the protective frame and making it easier for users to clean or maintain the protective frame structure later.

[0023] Example

[0024] refer to Figures 1 to 6This embodiment of an American-style ducted air conditioner's high-efficiency airflow guiding structure includes a duct body 1, a protective frame 2 snapped onto the bottom end of the duct body 1, an air outlet 3 at the bottom end of the protective frame 2, a first guide plate 4 installed on the inner wall of the air outlet 3, a connecting plate 18 threadedly connected to the bottom end of the duct body 1, the connecting plate 18 located inside the protective frame 2, a rotating shaft 21 rotatably connected to the bottom end of the connecting plate 18, a rotating plate 22 fixedly connected to the bottom end of the rotating shaft 21, a second guide plate 23 fixedly connected to the outer wall of the rotating plate 22, the second guide plate 23 being inclined, and a limit frame 24 fixedly connected to the outer side of the second guide plate 23. The position of the second guide plate 23 corresponds to the position of the bottom end of the air duct body 1. The rotating shaft 21 is installed at the center of the bottom end of the connecting plate 18. When in use, the air duct body 1 is started so that the hot and cold air is blown downward. The wind concentrated at the center point will be blown onto the second guide plate 23. Since the second guide plate 23 is inclined, it will generate a certain wind force to push it. Its rotating shaft 21 can make the rotating plate 22 rotate so as to drive the second guide plate 23 to rotate, thereby spreading the wind at the center point to the surroundings, and then exhausting it through the first guide plate 4. Thus, the wind exhausting through the first guide plate 4 can spread to the surroundings as soon as possible.

[0025] refer to Figure 5 The bottom end of the connecting plate 18 is provided with a screw hole 19, which extends into the interior of the air duct body 1. A bolt 20 is threadedly connected to the inside of the screw hole 19. The top of the bolt 20 is threaded into the interior of the air duct body 1 through the screw hole 19. The connecting plate 18 is threaded to the bottom end of the air duct body 1 through the screw hole 19 and the bolt 20. Due to the presence of the bolt 20, the screwing in of the bolt 20 can effectively fix the connecting plate 18 to prevent it from shifting. When it needs to be disassembled later, the bolt 20 can be unscrewed. It also facilitates the user to clean or maintain the structure on the connecting plate 18 later.

[0026] refer to Figure 2 A filter plate 25 is installed on the inner wall of the duct body 1. The filter plate 25 covers the inner side of the duct body 1. The position of the filter plate 25 corresponds to the position of the connecting plate 18. Due to the presence of the filter plate 25, the circulating air can be effectively filtered to prevent a large amount of dust and pollutants in the air from entering the interior of the duct body 1, thus achieving a good dust protection effect.

[0027] refer to Figures 1 to 6The bottom of the duct unit 1 has a positioning groove 16, which is located on the four sides near the corners of the bottom of the duct unit 1. The top of the protective frame 2 is fixedly connected to a positioning block 14 that matches the positioning groove 16. The positioning block 14 is engaged with the inside of the positioning groove 16. The bottom of the duct unit 1 has a sealing groove 17, and the top of the protective frame 2 is fixedly connected to a sealing ring 15 that matches the sealing groove 17. The sealing ring 15 is located on the inside of the positioning block 14 and covers the inside of the sealing groove 17. The top of the protective frame 2 is fixedly connected to an installation block 5, and the other side of the installation block 5 is attached to the outer wall of the duct unit 1. One side of the installation block 5 has a first slot 6 that extends into the interior of the duct unit 1. The inner wall of the first slot 6 has a second slot 7, and the inner side of the first slot 6 has a circular groove 8. The inner side of the first slot 6 is engaged with a first locking block 10, and the outer side of the first locking block 10 is fixedly connected to a second locking block 7. The second locking block 11, which matches the groove 7, engages inside the circular groove 8. Due to the presence of the positioning block 14, the engagement of the positioning block 14 can effectively limit the position of the protective frame 2, and also improve the accuracy of the insertion of the first locking block 10. By adjusting the second locking block 11 to a position that does not correspond to the second groove 7, the protective frame 2 can be effectively engaged to prevent displacement. The cooperation between the sealing ring 15 and the sealing groove 17 can effectively seal the connection point between the two, achieving a good dustproof and air leakage prevention effect. When the protective frame 2 structure needs to be disassembled for maintenance, the second locking block 11 is adjusted to a position corresponding to the second groove 7, and then the first locking block 10 can be directly pulled out. Then the positioning block 14 can be pulled out of the positioning groove 16, thus achieving the purpose of convenient disassembly and assembly of the protective frame 2, and also making it easier for users to clean or maintain the protective frame 2 structure later.

[0028] refer to Figures 2 to 6 A retaining spring 9 matching the second retaining block 11 is installed on the inner side of the circular groove 8. The other side of the second retaining block 11 is engaged with one side of the retaining spring 9. The second retaining block 11 is engaged with the inner side of the circular groove 8 through the retaining spring 9. A sealing block 12 is fixedly connected to one side of the first retaining block 10. The sealing block 12 covers one side of the first retaining groove 6. A protrusion 13 is fixedly connected to one side of the sealing block 12. The protrusion 13 has an arc-shaped corner. Due to the presence of the retaining spring 9, the retaining spring 9 can engage the second retaining block 11 at the second position, which can improve the stability of the engagement of the second retaining block 11 at the second position. At the same time, it can also effectively improve the stability of the engagement of the protective frame 2 at the second position.

[0029] Operating principle and advantages: When in use, start the duct unit 1 to blow hot and cold air downwards. The airflow concentrated at the center point will be blown onto the second guide plate 23. Because the second guide plate 23 is inclined, it generates a certain amount of airflow. Its rotating shaft 21 can rotate the rotating plate 22, thereby driving the second guide plate 23 to rotate, thus diffusing the air from the center point to the surrounding areas. The air is then discharged through the first guide plate 4, allowing the air discharged through the first guide plate 4 to diffuse to the surrounding areas immediately. The presence of bolts 20 effectively fixes the connecting plate 18 at the points where it is tightened, preventing displacement. When disassembly is needed later, simply unscrew the bolts 20. This also facilitates cleaning or maintenance of the structure on the connecting plate 18. The presence of the filter plate 25 effectively filters the circulating air, preventing a large amount of dust and pollutants from entering the interior of the duct unit 1, providing good dust protection. The presence of the positioning block 14 ensures proper positioning. The locking mechanism of block 14 effectively limits the position of the protective frame 2 and improves the accuracy of inserting the first locking block 10. Adjusting the second locking block 11 to a position that does not correspond to the second locking groove 7 effectively locks the protective frame 2 to prevent displacement. The cooperation between the sealing ring 15 and the sealing groove 17 effectively seals the connection point between the two, providing good dustproof and airproof performance. When the protective frame 2 needs to be disassembled for maintenance, the second locking block 11 is adjusted to a position corresponding to the second locking groove 7, allowing the first locking block 10 to be pulled out directly. Then, the positioning block 14 can be pulled out of the positioning groove 16, thus facilitating the disassembly and assembly of the protective frame 2 and making it easier for users to clean or maintain the protective frame 2 structure later. Due to the presence of the retaining spring 9, the retaining spring 9 can perform a secondary locking on the position of the second locking block 11, which can further improve the stability of the locking on the position of the second locking block 11 and effectively improve the stability of the locking on the position of the protective frame 2.
