Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, and in particular to a system window frame with a concealed drainage channel. Background Technology

[0002] As a key component of the building envelope, the system window frame not only undertakes structural functions such as supporting glass, transferring loads, and resisting wind pressure, but also needs to have excellent airtightness, watertightness, and thermal performance to meet the stringent requirements of modern high-performance buildings, especially passive low-energy buildings.

[0003] As energy-saving standards continue to rise, the design of system windows has evolved from a single function of thermal insulation to a multi-functional integration. Among these, the drainage system is a crucial component. Currently, most existing system windows employ exposed drainage hole structures, where drainage outlets are directly opened on the outer wall of the window frame. While this achieves basic drainage, the exposed drainage holes disrupt the integrity and aesthetics of the building facade. Furthermore, the drainage holes, constantly exposed to the external environment, are easily clogged by dust, fallen leaves, snow, etc., leading to poor drainage. Rainwater accumulation may then seep into the room, causing potential leaks. Long-term use may also induce corrosion of the building materials or failure of the internal insulation materials.

[0004] Therefore, it is necessary to design a system window frame with a concealed drainage channel. Utility Model Content

[0005] In order to overcome the shortcomings of existing systems where the drainage holes of the exterior windows are exposed, leading to easy blockage and affecting aesthetics, this utility model provides a system window frame with a hidden drainage channel.

[0006] The technical implementation scheme of this utility model is as follows: a system window frame with a concealed drainage channel, including an outer aluminum profile, an inner aluminum profile, a thermal insulation connecting strip, glass, a guide plate, a fixing plate, mounting blocks, bolts, and a concealed cleaning scraper. The inner aluminum profile is located on the right side of the outer aluminum profile. Two thermal insulation connecting strips connect the inner aluminum profile and the outer aluminum profile. Glass is located between the upper parts of the outer aluminum profile and the inner aluminum profile. A drainage cavity is located inside the outer aluminum profile. A guide plate inclined to the lower left is located inside the drainage cavity. A drainage outlet is opened on the lower left side of the outer aluminum profile. The drainage outlet is aligned with the guide plate. A fixing plate is fixed to the left side of the outer aluminum profile. Multiple mounting blocks are connected to the lower part of the fixing plate. A concealed cleaning scraper is inserted between the lower parts of the mounting blocks. The concealed cleaning scraper is threadedly connected to each mounting block with a bolt. The concealed cleaning scraper is located to the left of the drainage outlet and is horizontal and vertical to the fixing plate.

[0007] Furthermore, it also includes sealing strips and insulation layers. Sealing strips are connected between the left and right sides of the glass and the inner and outer aluminum profiles. An insulation layer is attached to the outside of the deflector, and the deflector is connected to the outer aluminum profile through the insulation layer.

[0008] Furthermore, it also includes a filter screen, which is installed on the upper part of the drainage cavity inside the outer aluminum profile, and the filter screen is located directly below the glass.

[0009] Furthermore, the surface of the deflector is coated with a hydrophobic coating, and the slope of the deflector is 1% to 3%.

[0010] Furthermore, both the outer and inner aluminum profiles are made of corrosion-resistant aluminum alloy and have been treated with fluorocarbon coating.

[0011] Furthermore, the scraping surface of the concealed cleaning scraper has a micro-serrated structure.

[0012] Beneficial effects: 1. This utility model sets the drain outlet inside the drainage cavity of the outer aluminum profile and uses a guide plate to guide the rainwater to flow to the lower left. At the same time, a hidden cleaning scraper is set on the left side of the drain outlet and is in a horizontal and vertical state with the fixed plate, forming a structural shield for the drain outlet. While ensuring a simple appearance, it can also prevent foreign objects from blocking the drainage channel and ensure long-term smooth drainage.

[0013] 2. This utility model blocks the direct heat conduction path between metal components by attaching an insulation layer to the outside of the air deflector plate and connecting it to the outer aluminum profile through the insulation layer. At the same time, the use of corrosion-resistant aluminum alloy profiles and fluorocarbon spraying treatment improves the weather resistance of the outer frame, thereby achieving the effects of suppressing local condensation, preventing profile corrosion, and extending the service life of the system window.

[0019] Example: A system window frame with a concealed drainage channel, such as Figures 1-4 As shown, the device includes an outer aluminum profile 1, an inner aluminum profile 2, a thermal insulation connecting strip 3, glass 4, a guide plate 6, a fixing plate 9, a mounting clip 10, bolts 11, and a concealed cleaning scraper 12. The inner aluminum profile 2 is located on the right side of the outer aluminum profile 1. Two thermal insulation connecting strips 3 connect the inner aluminum profile 2 and the inner aluminum profile 1. Both the outer aluminum profile 1 and the inner aluminum profile 2 are made of corrosion-resistant aluminum alloy and have a fluorocarbon coating, providing strong weather resistance, long service life, and adaptability to various climatic environments. Glass 4 is located between the upper parts of the outer aluminum profile 1 and the inner aluminum profile 2. A drainage chamber is located inside the outer aluminum profile 1, and a guide plate 6 inclined downwards to the left is located inside the drainage chamber. The surface of the guide plate 6 has a hydrophobic coating, and the inclination of the guide plate 6... The slope is 1% to 3% to reduce water flow resistance, promote rapid water discharge, and reduce water accumulation and scaling. A drain outlet is provided on the lower left side of the outer aluminum profile 1. The drain outlet is aligned with the guide plate 6. A fixing plate 9 is fixed to the left side of the outer aluminum profile 1. Multiple mounting blocks 10 are connected to the lower part of the fixing plate 9. A hidden cleaning scraper 12 is inserted between the lower parts of the mounting blocks 10. The scraping surface of the hidden cleaning scraper 12 has a micro-serrated structure to enhance the cleaning ability and effectively remove stubborn stains attached to the drain outlet. The hidden cleaning scraper 12 is threadedly connected to each mounting block 10 with a bolt 11. The hidden cleaning scraper 12 is located on the left side of the drain outlet and is in a horizontal and vertical state with the fixing plate 9.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes sealing strips 5 and insulation layer 7. Sealing strips 5 are connected between the glass 4 and the inner aluminum profile 2 and the outer aluminum profile 1 on both sides to ensure that the airtightness and watertightness meet the standards. The outer side of the guide plate 6 is covered with insulation layer 7, and the guide plate 6 is connected to the outer aluminum profile 1 through insulation layer 7, which not only enhances the heat insulation performance, but also prevents cold bridge.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, it also includes a filter screen 8. The filter screen 8 is installed on the upper part of the drainage cavity inside the outer aluminum profile 1. The filter screen 8 is located directly below the glass 4, effectively intercepting large particles of debris and reducing the risk of drainage channel blockage from the source.

[0022] In actual use, the system window is first installed at the building opening, with the outer aluminum profile 1 on the outside and the inner aluminum profile 2 on the inside. The two are connected by thermal insulation strip 3 to achieve structural connection and thermal break design, ensuring that the window has good thermal insulation performance and structural stability. The glass 4 is fixed between the upper part of the outer aluminum profile 1 and the inner aluminum profile 2 by sealing strip 5, forming multiple airtight and watertight barriers, effectively blocking the intrusion of external wind and rain, and improving the sound insulation, thermal insulation and weather resistance of the entire window.

[0023] When external rainwater seeps into the window seams under wind pressure, the water flows downwards along the surface of the profile and enters the drainage chamber inside the outer aluminum profile 1. This drainage chamber is a closed structure with a guide plate 6 inside, which is inclined to the lower left to effectively guide the accumulated water to flow in a predetermined direction. Since the surface of the guide plate 6 has a hydrophobic coating, the water forms droplets on its surface and slides off quickly, avoiding stagnation and diffusion, which significantly improves drainage efficiency. At the same time, the slope of the guide plate 6 is controlled between 1% and 3%, which ensures smooth gravity drainage and avoids affecting the structural space layout due to excessive slope. Under the guidance of the guide plate 6, the accumulated rainwater flows to the drainage outlet opened on the lower left side of the outer aluminum profile 1. This drainage outlet is aligned with the end of the guide plate 6 to ensure accurate water discharge. To prevent large particles such as sand and dust from entering the drainage chamber and causing blockage, a filter screen 8 is installed at the upper part of the drainage chamber, directly below the glass 4. This effectively intercepts pollutants, protects the downstream drainage channel, extends the service life of the system, and ensures long-term drainage reliability.

[0024] During long-term use of the drain outlet, scale or algae may form around the outlet and on the surface of the guide plate 6 due to water deposition, affecting drainage efficiency. To address this, a fixing plate 9 is fixed to the left side of the outer aluminum profile 1, with multiple mounting blocks 10 connected to its lower part. A concealed cleaning scraper 12 is inserted between the blocks. This scraper is located on the left side of the drain outlet and is horizontal and vertical to the fixing plate 9, achieving the effect of concealing the drain outlet and avoiding exposed holes that would damage the overall aesthetics of the building facade. When cleaning is required, the user can first unscrew the bolts 11 connecting them, and then pull them down along the blocks. The micro-serrated structure on the scraping surface can be used to physically scrape the drain outlet and the outer wall of the guide plate 6 to remove attached dirt. After cleaning, the scraper can be reinserted and locked with bolts 11. The operation is simple and requires no special tools, greatly improving maintenance convenience.

[0025] In addition, an insulation layer 7 is attached to the outside of the deflector plate 6, which connects it to the outer aluminum profile 1 through the insulation layer 7. This avoids direct contact between metal parts to form a linear thermal bridge, prevents condensation in high humidity environments, protects the internal structure from moisture corrosion, and extends service life. At the same time, both the outer aluminum profile 1 and the inner aluminum profile 2 are made of corrosion-resistant aluminum alloy and the surface is treated with fluorocarbon spraying, which combines high strength, weather resistance and aesthetics, and is suitable for various harsh environments such as coastal areas and industrial pollution.
