Description

Technical Field

[0001] This utility model relates to the field of window frame technology, specifically to an adjustable natural ventilation office building window frame structure. Background Technology

[0002] In modern office buildings, window frame structures are typically designed with fixed or simple mechanical opening mechanisms. Common types of these window frame structures include sliding windows, casement windows, and electrically controlled outward-opening windows.

[0003] Traditional indoor ventilation relies on adjusting the opening angle of windows to regulate airflow. However, this method, which relies on opening and closing windows, requires the windows to be open while maintaining ventilation, making it difficult to effectively prevent rainwater infiltration. This is particularly problematic in office buildings, where open windows are prone to water ingress during rain when no one is on duty after get off work or on holidays, requiring daily checks and causing inconvenience for building maintenance and management. Therefore, we propose an adjustable natural ventilation window frame structure for office buildings. Utility Model Content

[0004] The purpose of this invention is to address the problem that traditional indoor ventilation relies on adjusting the opening angle of windows to regulate airflow. However, this method, which relies on opening and closing windows, requires the windows to be open while maintaining ventilation, making it difficult to effectively prevent rainwater infiltration. This is particularly problematic in office buildings, where open windows are prone to water ingress during rain when no one is on duty after get off work or on holidays, requiring daily checks and causing inconvenience for building maintenance and management. This invention provides an adjustable natural ventilation window frame structure for office buildings.

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

[0006] An adjustable natural ventilation office building window frame structure includes two side ventilation columns arranged symmetrically in a mirror image. Each side ventilation column has an inner reinforcing plate fixedly connected to its inner side. An air inlet top beam is fixedly connected to the upper end of each side ventilation column, and a fixed bottom beam is fixedly connected to the lower side of each side ventilation column. The air inlet top beam has an air inlet on its outdoor side. An Ω-shaped guide channel is formed on the indoor side of each side ventilation column. Three sets of guide plates are rotatably installed on the inner walls of the Ω-shaped guide channel near its opening. These three sets of guide plates are spaced apart at the upper, middle, and lower positions corresponding to the side ventilation column. An extension plate is provided on the indoor side of the inner reinforcing plate, corresponding to the back side of the side ventilation column, with an opening on the extension plate corresponding to the rear side of the Ω-shaped guide channel. A ventilation grille is fixedly connected to the inner opening of the inner reinforcing plate.

[0007] Furthermore, each set of the deflector plates includes four S-shaped stainless steel plates with an aspect ratio of 3:1, and the radius of curvature of the deflector plates gradually increases from the inside to the outside along the length direction.

[0008] Furthermore, each of the multiple air deflectors is fixedly connected to an adjusting shaft on the indoor side. The outer end of the adjusting shaft passes through the side ventilation column and is keyed to a driven worm gear. The side ventilation column has a drive groove corresponding to the driven worm gear on the indoor side, and an adjusting worm is rotatably installed on the rear side of the drive groove. The adjusting worm meshes with the multiple driven worm gears for transmission. The two sides of the fixed bottom beam are rotatably installed with drive shafts corresponding to the bottom of the adjusting worm, and the inner end of the drive shaft meshes with the bottom of the adjusting worm through a bevel gear transmission mechanism.

[0009] Furthermore, an air intake channel is provided at the upper end of the Ω-shaped guide groove, and a spiral guide rib is fixedly connected to the inner wall of the air intake channel.

[0010] Furthermore, the side ventilation column is made of aluminum alloy profile, and the inner reinforcing plate is made of glass fiber reinforced nylon profile.

[0011] Furthermore, the outer center of the air inlet top beam has multiple air inlets evenly distributed, and each air inlet has a fixedly connected rainproof eave with its lower end tilted outward along its upper edge. The lower edge of the rainproof eave is located below the lower edge of the air inlet.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model features side ventilation columns. Air enters through the air intake beams at the top of the side ventilation columns. The air entering through the air intakes on the outer side of the air intake beams enters the Ω-shaped guide grooves at the top of the side ventilation columns, then impacts the S-shaped curved surfaces of three sets of guide plates. The air is intercepted by the guide plates and guided to one side of the room, then blown into the room through the ventilation grille. By adjusting the tilt angle of the guide plates, the direction of the airflow can be adjusted, ensuring ventilation inside and outside the office without opening the windows. This avoids the problem of rainwater seepage and improves the practicality and reliability of the office building window frame structure.

[0014] 2. This utility model uses a deflector plate to generate a Venturi effect by changing the curvature. Actual measurements show that this can increase airflow speed, reduce energy consumption, and improve ventilation efficiency.

[0015] 3. This utility model features an adjustable shaft that can be driven to rotate by the adjusting worm gear through the meshing of the driven worm wheel and the adjusting worm. The adjusting worm can be driven to rotate by the shaft through a bevel gear transmission mechanism, thereby enabling the adjustment of the tilt angle of the guide plate by rotating the shaft indoors. Furthermore, the self-locking capability of the adjusting worm and the driven worm wheel is used to maintain the rotation angle of the guide plate. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Please see Figures 1-4 This utility model provides an adjustable natural ventilation office building window frame structure, including side ventilation columns 1. Two side ventilation columns 1 are arranged symmetrically on the left and right sides, and an inner reinforcing plate 2 is fixedly connected to the inner side of each side ventilation column 1. An air inlet top beam 3 is fixedly connected to the upper end of each side ventilation column 1, and a fixed bottom beam 4 is fixedly connected to the lower side of each side ventilation column 1. An air inlet is opened on the side of the air inlet top beam 3 facing the outside. An Ω-shaped guide groove 5 is opened on the side of the side ventilation column 1 facing the inside. Three sets of guide plates 7 are rotatably installed on the inner walls of the two sides of the Ω-shaped guide groove 5 near the opening. The three sets of guide plates 7 are spaced apart at the upper, middle and lower positions corresponding to the side ventilation column 1. An extension plate is provided on the side of the inner reinforcing plate 2 facing the inside and corresponding to the back side of the side ventilation column 1. An extension plate is provided on the back side of the Ω-shaped guide groove 5. A ventilation grille 9 is fixedly connected to the inner opening of the inner reinforcing plate 2.

[0023] In this embodiment, each set of guide plates 7 includes four S-shaped stainless steel plates with a length-to-width ratio of 3:1, and the radius of curvature of the guide plates 7 gradually increases from the inside to the outside along the length direction; by using the guide plates 7, the Venturi effect is generated by the curvature change, which can increase the airflow speed, reduce energy consumption, and improve ventilation efficiency.

[0024] In this embodiment, each of the multiple guide vanes 7 is fixedly connected to an adjusting shaft 10 on the indoor side. The outer end of the adjusting shaft 10 passes through the side ventilation column 1 and is keyed to a driven worm gear 12. A drive groove is provided on the indoor side of the side ventilation column 1 corresponding to the position of the driven worm gear 12, and an adjusting worm 11 is rotatably installed on the rear side of the drive groove. The adjusting worm 11 meshes with the multiple driven worm gears 12 for transmission. Drive shafts 13 are rotatably installed on both sides of the fixed bottom beam 4 corresponding to the bottom of the adjusting worm 11, and the drive shafts 13 are rotatably installed on both sides of the fixed bottom beam 4. The inner end of the rotating shaft 13 is driven by the bottom of the adjusting worm 11 through a bevel gear transmission mechanism. The adjusting shaft 10 is driven to rotate by the adjusting worm 11 through the meshing of the driven worm wheel 12 with the adjusting worm 11. The adjusting worm 11 is driven to rotate by the rotating shaft 13 through the bevel gear transmission mechanism, thereby realizing the adjustment of the tilt angle of the guide plate 7 by rotating the rotating shaft 13 indoors. The self-locking ability of the adjusting worm 11 and the driven worm wheel 12 is used to maintain the rotation angle of the guide plate 7.

[0025] In this embodiment, an air intake channel 6 is provided at the upper end of the Ω-shaped guide groove 5, and a spiral guide rib is fixedly connected to the inner wall of the air intake channel 6. Through the air intake channel 6 and the spiral guide rib on the inner wall of the air intake channel 6, the airflow is guided to rotate and accelerate. While accelerating the airflow, it also centrifugally separates dust, preventing dust from entering the room and improving indoor air quality. Furthermore, the spiral guide rib design also reduces noise, making the indoor environment quieter and more comfortable.

[0026] In this embodiment, the side ventilation column 1 is made of aluminum alloy profile, and the inner reinforcing plate 2 is made of glass fiber reinforced nylon profile. Aluminum alloy profiles have advantages such as light weight, high strength, corrosion resistance, and ease of processing and forming, which can meet the strength and stability requirements of the window frame structure while reducing the overall weight of the window frame, facilitating installation and maintenance. Glass fiber reinforced nylon profiles have characteristics such as high strength, high rigidity, wear resistance, and aging resistance, which can further improve the strength and durability of the inner reinforcing plate 2, ensuring the stability and safety of the window frame structure.

[0027] In this embodiment, multiple air inlets are evenly spaced along the outer center of the air inlet beam 3, and each air inlet is fixedly connected to a rainproof eave 8 with its lower end sloping outwards along its upper edge. The lower edge of the rainproof eave 8 is horizontally positioned below the lower edge of the air inlet. The rainproof eave 8 effectively prevents rainwater from seeping into the room from the air inlets without affecting airflow, thus improving the practicality and reliability of the window frame structure. When rainwater falls from above, the rainproof eave 8 guides the rainwater away from the air inlets, ensuring the air inlets remain dry and preventing rainwater from affecting the indoor environment. This design not only improves ventilation but also enhances the waterproof performance of the window frame structure, providing a more comfortable and safer indoor environment for office building users.

[0028] The working principle and usage process of this utility model are as follows: During use, air is introduced through the side ventilation columns 1 on both sides, and the upper ends of the side ventilation columns 1 are connected to the air intake beam 3. The air entering through the air intake on the outer side of the air intake beam 3 enters the Ω-shaped guide groove 5 through the upper ends of the side ventilation columns 1 on both sides. Then, it impacts the S-shaped curved surface of the three sets of guide plates 7, is intercepted by the guide plates 7, and is guided to the indoor side. It is then blown into the room through the ventilation grille 9. By adjusting the tilt angle of the guide plates 7, the direction of airflow can be adjusted. This ensures ventilation inside and outside the office without opening the windows, thus avoiding the problem of rainwater seepage and improving the practicality and reliability of the office building window frame structure.
