Description

Technical Field

[0001] This utility model relates to the field of window structure technology, specifically to a hidden drainage strip with an outward-opening window system. Background Technology

[0002] Concealed drainage system windows are a type of window that cleverly conceals the drainage channel within the window frame through a well-designed drainage structure. This structure not only effectively prevents rainwater from seeping into the room but also enhances the window's aesthetics, avoiding visual pollution from exposed drainage holes. Typically, concealed drainage system windows are equipped with multiple drainage outlets, forming a complete drainage path. Rainwater is smoothly discharged through gravity, thus improving the window's functionality and safety under adverse weather conditions. It's worth noting that these system windows often use thermally broken aluminum profiles as the core frame material. Thermally broken aluminum (also known as insulated aluminum profiles, thermally broken aluminum alloy, or thermally broken profiles) offers superior performance compared to ordinary aluminum alloy profiles: because aluminum alloy is a metal with high thermal conductivity, it easily becomes a "bridge" for heat transfer when there is a large temperature difference between indoors and outdoors, resulting in poor thermal insulation. Thermally broken aluminum, however, uses a rigid plastic material to break the aluminum alloy in the middle, blocking the heat transfer path and significantly improving the thermal insulation effect. Meanwhile, the combination of thermally broken aluminum windows and doors with double-glazed design can further achieve energy saving, sound insulation, noise reduction, dust prevention and waterproofing functions, with its water tightness and air tightness advantages being particularly prominent.

[0003] Utility model patent CN216517696U discloses a concealed drainage structure for windows and doors, including a sash profile and a frame profile. A sealing strip is provided between the sash profile and the glass. A first drainage outlet is located in the glass mounting groove at the top of the sash profile, a second drainage outlet is located at the bottom of the sash profile, and a third drainage outlet is located on one side of the top of the frame profile. The first, second, and third drainage outlets constitute a concealed drainage route. Compared with existing technologies, this utility model, through a rationally designed concealed drainage structure, avoids direct wind pressure blowing into the drainage holes, reducing the possibility of rainwater backflow; rainwater drains by its own gravity, resulting in a larger flow rate; the drainage fins disperse rainwater, preventing direct water flow onto the windowsill and preventing wall cracks and water seepage over time; there are no exposed drainage holes on the aluminum panel, eliminating the need for windproof covers and improving the aesthetics of windows.

[0004] While the existing technologies described above achieve concealed drainage, the drainage channels are connected to the frame and sash profiles. In windy weather without rain, external dust and debris can easily enter the interior of the frame and sash profiles through the openings in the drainage channels. Over time, these impurities may clog the drainage channels, thus affecting the normal drainage function of the concealed drainage structure. Therefore, we propose a concealed drainage system with a subframe and outward opening design. Through optimized design, this system ensures unobstructed drainage channels and further improves the lifespan of the window. Utility Model Content

[0005] The purpose of this utility model is to provide a hidden drainage strip with an outward-opening window system structure to solve the problems mentioned in the background art.
