Description
Technical Field
[0001] This utility model relates to the field of building door and window technology, and in particular to an outward-opening window with a drainage diversion structure. Background Technology
[0002] Currently, outward-opening windows commonly encounter the problem of rainwater seepage during rainy days. In particular, due to structural limitations, rainwater easily flows down and accumulates at the bottom joint between the window sash and the window frame, eventually seeping into the room and affecting its use. Some existing solutions attempt to alleviate this problem by adding sealing strips or improving drainage holes, but sealing strips are prone to aging and deformation after long-term use, and drainage holes are easily flooded by rainwater in strong winds, so the actual seepage prevention effect is not ideal. In addition, some complex drainage devices are inconvenient to install and difficult to maintain, making them difficult to widely apply in ordinary buildings.
[0003] Therefore, a simple, easy-to-install, and reliable external window drainage solution is needed. Summary of the Invention
[0004] The purpose of this utility model is to solve the problem that in the existing technology, due to structural limitations, rainwater can easily flow down and accumulate on the glass surface at the bottom joint between the window sash and the window frame, and then seep into the room, affecting its use. The proposed outward-opening window has a drainage and diversion structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An outward-opening window with a drainage and diversion structure is used to drain and divert rainwater from the closed window sash after the window sash is installed, preventing rainwater from entering the house through the joint between the window sash and the bottom of the window frame. The window frame includes an outward-opening window sash frame that is movably installed on the window frame. The inner side of the window sash frame is fixed with double-glazed glass with an internal vacuum. A drainage diversion mechanism is detachably installed on the outside of the window frame via a dovetail groove and tenon structure. It is used to guide rainwater sliding down the window sash frame and double-glazed glass to both sides to prevent rainwater from entering the bottom joint of the window frame and window sash frame.
[0006] Furthermore, the drainage diversion mechanism includes a base that is detachably installed on the outside of the window frame via a dovetail groove and tenon structure, extending to one side of the window frame. A diversion strip is fixed on the top of the base, and a flexible sealing lip with an inwardly curved end that does not affect the opening and closing of the window frame is fixed on the top of the diversion strip. The inner side of the flexible sealing lip is tightly and flexibly fitted to the closed window frame.
[0007] Furthermore, the outer side of the guide strip is provided with a guide slope that guides the flow outward and to both sides, and both ends of the guide strip are fixed with drainage lips that curl inward.
[0008] Furthermore, fixing blocks are fixed on both inner walls of the window frame, and limiting cranks are movably installed on the side of the two fixing blocks that are close to each other through a movable shaft. The two limiting cranks are movably connected to the opposite sides of the window frame through a movable shaft.
[0009] Furthermore, sliders are slidably mounted on the inner walls of both sides of the window frame above the fixing block via guide rails. An upper crank and a lower crank are movably mounted on the outer side of the slider via a rotating shaft. The end of the upper crank is movably connected to the outer side of the window sash frame via a movable shaft, and the end of the lower crank is movably connected to the outer side of the limiting crank via a rotating shaft.
[0010] Furthermore, a handle is rotatably mounted on the window frame via a rotating shaft, and a rotatable L-shaped locking block is fixed on the outside of the handle. A U-shaped block is fixed on the window frame that can disengage from and engage with the L-shaped locking block of the handle.
[0011] In this application, the drainage diversion structure mainly changes the natural flow direction of rainwater through a detachable diversion mechanism to prevent it from accumulating at the joint between the window sash and the window frame. The outside of the window frame is provided with a dovetail groove, and the base of the drainage diversion mechanism is installed with it through a tenon. The diversion strip is fixed on the base, and the flexible sealing lip at the top of it maintains flexible contact with the surface of the window sash frame when the window sash is closed. When rainwater flows down the surface of the double-glazed glass, it is first intercepted by the sealing lip, and then diverted to both sides along the diversion slope on the outside of the diversion strip. Finally, it drips from the drainage lip edge that curls inward from the end, preventing water from accumulating at the bottom of the window frame. The opening and closing of the window sash is achieved by a crank-connecting rod mechanism. Limiting cranks are installed on the fixed blocks on the inner walls of both sides of the window frame. The limiting cranks are connected to the side of the window sash frame. The slider slides up and down along the guide rail. The upper and lower cranks are linked with the window sash frame and the limiting cranks respectively to achieve smooth outward opening of the window sash. The handle on the window sash frame drives the L-shaped locking block to rotate and engage with the U-shaped block on the window frame to complete the locking.
[0012] In this utility model, the outward-opening window with drainage and flow guiding structure has a clear rainwater guiding effect. By guiding water to both sides through the slope and lip, it effectively reduces the possibility of water seepage from the bottom gap. The flow guiding mechanism uses a dovetail groove and tenon joint, which makes it easy to install and disassemble, and convenient to clean or replace; The flexible sealing lip fits flexibly with the window frame, without affecting the normal opening and closing of the window, and can accommodate different installation errors. The overall structure requires no changes to the existing window frame and sash profiles, making it suitable for most existing outward-opening windows to be retrofitted. The crank-connecting rod mechanism ensures smooth window opening, accurate positioning, and minimal wobbling. The rolled-up drainage lip design prevents rainwater from flowing back or being blown away by the wind, enhancing the reliability of drainage. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] In one embodiment Reference Figure 1-4 A drainage and diversion structure for outward-opening windows is proposed. This structure is mainly designed to address the problem that rainwater can easily seep into the room from the bottom joint between the window sash and the window frame 1 when the window sash is closed. Its core is to add a detachable diversion mechanism to the outside of the window frame 1 to guide the rainwater to the sides of the window and discharge it, so as to avoid the rainwater accumulating at the joint between the window sash frame 2 and the window frame 1.
[0017] The window frame 1 is made of common aluminum alloy profiles. The window sash frame 2 is installed on the window frame 1 via a hinge structure, allowing it to open outwards. Double-glazed glass 3 with internal vacuum is fixedly installed on the inner side of the window sash frame 2 to improve thermal insulation and soundproofing performance. The drainage and diversion mechanism is installed on the lower edge of the exterior side of the window frame 1 using a dovetail groove and tenon structure. Specifically, a dovetail groove is pre-machined on the lower edge of the window frame 1, and a matching tenon is provided at the corresponding position on the base 9 of the drainage mechanism. During installation, the tenon is simply pushed in along the direction of the dovetail groove to secure it. It can also be slid out in the opposite direction when replacement or cleaning is required.
[0018] The flow guiding mechanism consists of a base 9, a flow guiding strip 10, and a flexible sealing lip 13. The base 9 is made of rigid PVC material, which has a certain rigidity to ensure that it will not deform after installation. The flow guiding strip 10 is made of soft TPU material and is integrally formed with the base 9 through a co-extrusion process. Its outer surface is designed as a smooth flow guiding slope 11 that slopes outward and to both sides. The top of the flow guiding strip 10 is provided with a flexible sealing lip 13, which is made of silicone and has an inwardly bent end. When the window is closed, the inner side of the flexible sealing lip 13 will form a gentle fit with the outdoor surface of the window frame 2. This fit will not affect the normal opening and closing of the window, but can effectively prevent rainwater from flowing directly to the seam below.
[0019] At both ends of the guide strip 10, there are inwardly curled drainage lips 12. This structure ensures that when rainwater flows to the end, it forms water droplets that drip smoothly and will not flow back along the bottom of the guide strip 10 due to the adsorption effect.
[0020] The opening of the window sash is controlled by a crank-connecting rod mechanism. Fixed blocks 7 are fixed on the inner walls of both sides of the window frame 1. The limiting crank 8 is installed on the fixed blocks 7 through a movable shaft, and the other end is connected to the side of the window sash frame 2. Slider 4 is also provided on both sides of the window frame 1. The slider 4 can slide up and down along the guide rail. The upper crank 5 and the lower crank 6 are installed on the outside of the slider 4 through a rotating shaft. The upper crank 5 is connected to the outside of the window sash frame 2, and the lower crank 6 is connected to the outside of the limiting crank 8. When the window sash is opened, the handle drives the connecting rod mechanism to move, so that the slider 4 slides along the guide rail. Through the linkage of the upper crank 5, the lower crank 6 and the limiting crank 8, the window sash can be opened smoothly outward.
[0021] A handle is installed on the window frame 2, and a rotatable L-shaped locking block is fixed on the outside of the handle. A U-shaped block is fixed at the corresponding position on the window frame 1. When the window is closed, rotating the handle causes the L-shaped locking block to engage with the U-shaped block, thereby locking the window.
[0022] When used in rainy weather, rainwater flows down the surface of the double-glazed glass 3. When it reaches the bottom, it is first intercepted by the flexible sealing lip 13 and then guided to the guide slope 11. As the slope is inclined outward and to both sides, the rainwater will flow to both sides of the window and finally drip from the drainage lip 12. The whole process completely guides the rainwater to the area where the window frame 2 and the window frame 1 meet, thereby effectively preventing rainwater from seeping into the room.
[0023] However, as is well known to those skilled in the art, the working principles and wiring methods of the base 9, guide strip 10, guide slope 11, flexible sealing lip 13 and drainage lip 12 are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
