Description

Technical Field

[0001] This utility model relates to the field of door and window processing, and in particular to a door and window that prevents rainwater leakage. Background Technology

[0002] As a key component of building envelope, doors and windows play a crucial role in ensuring the safe isolation and sealing of indoor and outdoor spaces. Under various climatic conditions, especially in windy and rainy weather, the waterproofing performance of doors and windows is paramount, directly impacting building durability, indoor comfort, and the occupant experience. Therefore, developing high-performance waterproof doors and windows remains a key technical challenge that the building door and window industry continuously focuses on and strives to address.

[0003] Currently, most waterproof doors and windows on the market rely on high-performance sealing strips to enhance the sealing of gaps, thus serving as the primary means of preventing rainwater intrusion. Some products also include simple rain shelters, attempting to initially intercept rainwater before it reaches the sealed areas. These methods form the basis of traditional door and window waterproofing technology.

[0004] However, the aforementioned existing technologies have obvious limitations: firstly, relying solely on the sealing strip for passive waterproofing makes them prone to failure under strong wind pressure or when the strip ages; secondly, simple rain shelters have low diversion efficiency, making it difficult to cope with drifting rain or splashing water, and they cannot solve the problem of rainwater accumulating and backflowing on the windowsill. Utility Model Content

[0005] To address the shortcomings of the existing technologies, this paper aims to provide a door and window solution that combines active drainage and multiple sealing to significantly improve waterproof reliability.

[0006] The technical solution adopted by this utility model to solve its technical problem is a rainproof door and window, comprising: Door and window bodies, awnings, and drainage systems; The main body of the door and window is a rectangular vertical frame structure, which is the basic load-bearing component of the door and window. Sealing strips are installed on its edges to enhance the sealing performance of the door and window edges. A window canopy is provided above the top of the main body of the door and window, and a drainage mechanism is provided below the window canopy and on the lower part of the main body of the door and window near the outside.

[0007] The awning includes a fan-shaped opening and closing mechanism, a frame, a fan-shaped guide rail, a fixing post, a waterproof cloth, and a sun-protective cloth. The fan-shaped opening and closing mechanism is controlled by a drive source to control the opening and closing angle of the awning. The frame is the supporting structure of the awning. The root of the frame (the end closest to the main body of the door and window) is fixed to the fan-shaped opening and closing mechanism through the fixing post, and the end (the end away from the main body of the door and window) extends outward, forming an umbrella-shaped radial structure. The waterproof cloth and the sun-protective cloth are fixedly installed at the end of the frame, and the waterproof cloth is placed above the sun-protective cloth. The fan-shaped guide rail is an arc-shaped track.

[0008] The main body of the door and window includes a lower window body. The drainage mechanism is a long strip structure and is fixedly connected to the lower window body. The drainage mechanism includes a guide plate, a water outlet groove, a water outlet, and a platform. The guide plate is located on the lower window body, between the sealing strip and the platform. The lower window body has multiple water outlet grooves, and the water outlet grooves have water outlets for draining rainwater outside the window. The platform is an inclined slope and is fixedly installed between the guide plate and the water outlet grooves, with its higher side close to the guide plate and its lower side close to the water outlet grooves.

[0009] The guide plate includes a flow channel, a first flow port and a second flow port. The first flow port is close to the sealing strip and the second flow port is close to the platform. Multiple sets of the flow channels are arranged on the guide plate to form an "S" or "Z" shaped maze-like channel.

[0010] This utility model provides a rainwater-proof door and window. The awning at the top of the door and window serves as the first line of defense, effectively intercepting and diverting most of the impacting rainwater, reducing the amount of rainwater directly impacting the door and window. A unique vortex-shaped drainage channel below it utilizes centrifugal force to accelerate rainwater discharge tangentially, completely eliminating backflow. Combined with the labyrinthine water-blocking ribs and drainage channels on the guide plate, forming multiple meandering paths, and working in conjunction with the sealing strip, it constitutes a double insurance of "drainage + blocking," ultimately forming a multi-level seepage prevention and drainage system that progresses from the outside in. This significantly improves the reliability, drainage efficiency, and overall durability of the door and window under severe weather conditions such as strong winds and heavy rain.

[0013] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0014] like Figures 1 to 4 As shown, the present invention provides a rainproof door and window, including a door and window body 1, a window canopy 2, and a drainage mechanism 3; In one specific embodiment, the main body 1 of the door and window is a rectangular vertical frame structure, which is the basic load-bearing component of the door and window. A sealing strip 4 is installed on its edge to enhance the sealing of the door and window edge and prevent rainwater from seeping in from the gap. A window canopy 2 is provided above the top of the main body 1 of the door and window, and a drainage mechanism 3 is provided below the window canopy 2 and below the main body 1 of the door and window on the outdoor side. In one specific embodiment, in order to intercept most of the outdoor rainwater, this utility model is provided with a window awning 2. The window awning 2 includes a fan-shaped opening and closing mechanism 5, a frame 6, a fan-shaped guide rail 7, a fixing post 8, a waterproof cloth 9, and a sun-protective cloth 10. The fan-shaped opening and closing mechanism 5 is controlled by a drive source to control the opening and closing angle of the window awning 2. The frame 6 is the supporting structure of the window awning 2, made of radially arranged fan-shaped metal rods or high-strength engineering plastics. The root of the frame 6 (the end closest to the door and window body 1) is fixed to the fan-shaped opening and closing mechanism 5 through the fixing post 8, and the end (the end away from the door and window body 1) extends outward, forming an overall "umbrella-shaped" radial structure. The individual rods of frame 6 are distributed parallel and equidistantly to ensure uniform force distribution; the fan-shaped guide rail 7 is an arc-shaped track made of stainless steel or aluminum alloy, which adapts to the opening and closing angle of the awning 2 and ensures that the frame 6 moves without jamming; a waterproof cloth 9 and a sun-proof cloth 10 are fixedly installed at the end of the frame 6 (the end away from the main body of the door and window 1). The waterproof cloth 9 is placed above the sun-proof cloth 10 and is composited with the sun-proof cloth 10 through a hot-pressing process to form a "waterproof-sun-proof" double-layer composite structure. The waterproof cloth 9 can quickly guide the vertically falling rainwater to the outside, while the composite sun-proof cloth 10 can block the radiation of ultraviolet rays and protect the main body of the door and window 1 and the sealing strip 4; In one specific embodiment, to construct multiple, coordinated waterproof defenses and accelerate drainage, this utility model also includes a drainage mechanism 3. The main body 1 of the door and window includes a lower window 12. The drainage mechanism 3 is a long strip structure, fixedly connected to the lower window 12 of the main body 1. The drainage mechanism 3 includes a guide plate 11, a water outlet 13, a water outlet 14, and a platform 15. The guide plate 11 is located on the lower window 12, between the sealing strip 4 and the platform 15. The lower window 12 has multiple water outlets 13, and each water outlet 13 has a water outlet 14 for draining rainwater. Outside the window, the water outlet 13 is a vortex-shaped guide channel. Utilizing the principles of fluid dynamics, it causes the flowing water to swirl out tangentially, away from the drain outlet, completely eliminating the possibility of rainwater backflow due to wind or wall adhesion. The platform 15 is an inclined slope, fixedly installed between the guide plate 11 and the water outlet 13. Its higher side is close to the guide plate 11, and its lower side is close to the water outlet 13. The higher side smoothly transitions to the guide plate 11, and the lower side connects to the edge of the water outlet 13. The higher side forms a "water-blocking step" with the frame of the lower window 12, while the lower side guides rainwater into the water outlet 13 through a gradually decreasing slope. In one specific embodiment, at the joint between the window frame and the window sash, multiple staggered water-blocking ribs and drainage channels 16 are designed to form an "S" or "Z" shaped maze-like channel, namely a guide plate 11. The guide plate 11 also includes a first drainage port 17 and a second drainage port 18. The first drainage port 17 is close to the sealing strip 4, and the second drainage port 18 is close to the platform 15. The maze path of the guide plate 11 itself can effectively block the direct intrusion of rainwater due to wind pressure even without the sealing strip, and together with the sealing strip 4, it forms a double insurance of "drainage + blocking". The working process of this utility model is as follows: The working process of a rainwater-proof door and window is divided into an initial rainfall stage, a rainwater overflow stage, and a seepage-proof reinforcement stage; Initial rainfall stage: When rainfall begins, outdoor rainwater falls vertically or is affected by wind and impacts doors and windows at an angle. At this time, the awning 2, as the first line of defense, starts to work. The radially arranged frame 6 is connected to the fan-shaped opening and closing mechanism 5 through the fixed column 8, supporting the composite layer of waterproof cloth 9 and sun-proof cloth 10. The inclined frame 6 quickly guides the vertically falling rainwater along the surface of the waterproof cloth 9 to the outside, reducing the amount of rainwater that directly impacts the main body of the door and window 1. Rainwater overflow stage: Rainwater that is not completely intercepted by the awning 2 (such as rain caused by wind or rainwater splashed in through the gap between the opening and closing of the awning 2) falls to the drainage mechanism 3 and enters the second anti-seepage process. The rainwater first comes into contact with the inclined platform 15, causing the rainwater to flow into the outlet trough 13 along the inclined direction. After entering the outlet trough 13, the rainwater rotates and flows along the tangent of the vortex-shaped trough, forming centrifugal force, which accelerates the flow of rainwater towards the outlet 14 and prevents it from accumulating in the trough. Anti-seepage reinforcement stage: When a small amount of rainwater breaks through the water barrier of the platform 15, the labyrinth-type diversion channel 16 of the guide plate 11 activates the anti-seepage function. The diversion channel 16 is in the shape of "S" or "Z" (the first diversion port 17 is close to the sealing strip 4, and the second diversion port 18 is close to the platform 15). By changing the direction of rainwater flow multiple times, the residence time of rainwater on the surface of the guide plate 11 is extended. Gravity forces the rainwater to flow along the channel towards the second diversion port 18, avoiding direct penetration to the sealing strip 4 area. The above-disclosed embodiments are merely specific examples of this utility model. However, the embodiments of this utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
