[0002] As we all know, building doors and windows, as an important component of buildings, have a significant impact on the quality of the indoor environment. Water accumulation on the exterior window frames is not only difficult to clean, but also easily corrodes the doors and windows. Especially in severe weather such as heavy rain, rainwater can easily flow back into the interior walls, causing mold and other problems on the walls around the doors and windows. Summary of the Invention

[0003] In view of this, this utility model proposes a water diversion system for reusing existing exterior window facades, which aims to solve the problems of water accumulation and retention in existing exterior window frames that are difficult to clean and easily corrode doors and windows, causing mold growth on the walls around the doors and windows.

[0004] This utility model proposes a water diversion system for reusing existing window facades. The system includes an outer window frame and glass installed within the frame. The outer window frame has a water-diverting keel plate positioned above the bottom groove of the frame to divert rainwater from the glass into the groove. The frame also has a glass cleaning mechanism for sliding and cleaning the glass. Above the outer support structure on the outside of the bottom groove, the frame has a drainage mechanism connected to a drainage hole for protecting the support structure and diverting rainwater from the bottom groove.

[0005] Furthermore, in the aforementioned water diversion system for the reused exterior window facade, the drainage mechanism includes: a water-draining cover disposed on the outside of the outer support body, the water-draining cover being used to protect the outer wall of the outer support body and to divert rainwater; a drainage hole provided on the outer support body, which is connected to the bottom groove of the exterior window frame; and a lower pipe detachably inserted through the water-draining cover, and the lower pipe being detachably connected to the drainage hole, so that rainwater in the bottom groove can be discharged through the drainage hole and the lower pipe.

[0006] Furthermore, in the aforementioned water diversion system for reusing the exterior window facade, the top of the water diversion cover is provided with a water diversion arc surface, and the front side wall of the water diversion cover is provided with a water diversion slope, the top edge of which is connected to the water diversion arc surface.

[0007] Furthermore, in the aforementioned water diversion system for the reused exterior window facade, the downpipe has an inverted L-shaped structure, with its horizontal connecting pipe screwed to the drainage hole and the vertical drainage pipe arranged downwards.

[0008] Furthermore, in the aforementioned water diversion system for reusing exterior window facades, the glass cleaning mechanism includes: a handle plate, disposed on the front side of the glass, and both ends of the handle plate are disposed on the two side plates of the exterior window frame in a position-adjustable manner along the height direction; and a cleaning brush, disposed on the inner side of the handle plate, for cleaning the glass.

[0009] Furthermore, in the aforementioned water diversion system for reusing the exterior window facade, the exterior window frame is provided with a locking component, which has a locking state for locking the handle plate to the exterior window frame and a yielding state for avoiding the adjustment of the handle plate position.

[0010] Furthermore, in the aforementioned water diversion system for the reused exterior window facade, each side panel of the exterior window frame is provided with a sliding groove arranged along the height direction, and each sliding groove is provided with a sliding plate. The sliding plate is slidably disposed in the sliding groove, and the two ends of the handle are respectively connected to the two sliding plates to guide the sliding of the handle. The sliding groove and the sliding plate are provided with a friction layer to increase the friction between them so that the handle can stop at its position when it loses external moving force.

[0011] Furthermore, in the aforementioned water diversion system for reusing the exterior window facade, a water diversion surface is provided on the top wall of the outer support entity to divert rainwater and allow it to flow into the bottom trough.

[0012] Furthermore, in the aforementioned water diversion system for reusing exterior window facades, the water diversion surface is a sloping surface that is arranged downwards from the outer wall away from the bottom trench to the inner wall near the bottom trench, and the slope is 0.2%-0.3%.

[0013] Furthermore, in the aforementioned water diversion system for the reused exterior window facade, the water diversion keel plate is an inverted equilateral triangle structure, the side length of which is equal to the distance between the top wall of the water diversion keel plate and the outer support solid part.

[0014] This utility model provides a water drainage system for reusing existing window facades. It uses a water-draining keel plate on the window frame to divert rainwater from the glass into a bottom groove. A glass cleaning mechanism on the window frame cleans the glass by sliding it up and down. A drainage mechanism drains the rainwater from the bottom groove and protects and diverts rainwater from the external support structure, preventing water accumulation in the bottom groove and external support structure. This system provides waterproofing without damaging the original window and maintains the overall aesthetic appearance of the facade. This water drainage system for reusing existing window facades is simple, easy to construct, and facilitates cleaning of the glass facade.

[0015] Furthermore, a water-draining surface is formed by processing the edge of the window bottom frame. For example, the original horizontal surface is processed into a 0.2%-0.3% slope, and holes are drilled on the outside of the bottom frame to form drainage holes. These drainage holes ensure that residual water from the glass flows into the bottom frame for easy drainage. At a position 15mm above the bottom frame, a 15mm inverted equilateral triangle is made from scrap keel to serve as a water-draining keel plate. It is anchored to the inner frame with rivets, saving costs and providing waterproofing without damaging the original exterior window. The drainage hole is connected to the bottom pipe by threads to increase the drainage effect. This way, water will not remain on the bottom surface of the exterior window frame when draining, but will be discharged directly from the bottom pipe. To ensure aesthetics, water-draining covers are installed on the outside of multiple bottom pipes and multiple drainage holes using fixing bolts. To protect the bottom pipes, the outer surface of the water-draining covers is chamfered to form a water-draining arc surface and a water-draining slope, preventing water accumulation. The device is simple to install, easy to construct, and significantly improves the waterproofing effect.

[0016] Furthermore, by adding corresponding grooves on both sides of the outer window frame, sliders are installed in the grooves, and handles are installed on the sliders. Cleaning brushes are installed on the handles. When the cleaning brushes are not in use, they are held in place by locking parts on both sides, i.e., movable clips. When in use, the locking parts on both sides are flipped upwards through this rotating connecting component to move away from the handles. Then, the handles can be dragged by hand to move the cleaning brush up and down on the glass to clean it. Cleaning the glass with the cleaning brush makes it convenient to clean.

[0031] In this embodiment, a water-guiding surface 121 is provided on the top wall of the outer support entity 12 located outside the bottom groove 11 on the outer window frame 1. This surface is used to guide rainwater into the bottom groove 11. Specifically, the water-guiding surface 121 is a sloping surface that slopes downwards from the outer wall away from the bottom groove 11 to the inner wall near the bottom groove 11, and the slope is 0.2%-0.3%.

[0032] See also Figures 1 to 4 The glass cleaning mechanism 4 includes: a handle 41, a cleaning brush 42, and a locking member 43; wherein, the handle 41 is disposed on the front side of the glass 2, and both ends of the handle 41 (e.g., Figure 2 The left and right ends shown are both mounted on the side plates of the outer window frame 1 in a position-adjustable manner along the height direction; the cleaning brush 42 is mounted on the inner side of the handle plate 41 for cleaning the glass 2. The outer window frame 1 is provided with a locking member 43, which has a locking state for locking the handle plate 41 to the outer window frame 1 and a clearance state for avoiding the position adjustment of the handle plate 1.

[0033] Specifically, the two ends of the handle 41 are slidably mounted on the two side plates of the outer window frame 1 via guide self-locking components 44, which guide the handle 41 and allow it to stop in its position after the external force is removed, ensuring that the handle 41 will not fall directly down and can only be manually slid up and down by a person. A cleaning brush 42 is located on the inner side of the handle 41 for cleaning the glass 2. A locking member 43 is movably mounted on the top of the outer window frame 1 to switch between a locked state and a clearance state. The locking member 43 can be a movable clip with a slot 431. The locking member 43 is rotatably mounted on the top of the outer window frame 1. When rotated to the position where the slot 431 faces downwards, it is in a locked state, allowing the handle 41 to be secured within the slot 431, thus fixing the handle 41 to the locking member 43 and locking it in place. The locking member 43 can also be rotated to the position where the slot 431 faces outwards or upwards, in a clearance state, to allow for adjustment of the handle 1's position, enabling the cleaning brush 42 on the handle 1 to clean the top of the glass 2. In this embodiment, the top of the locking member 43 (relative to...) Figure 1 (As shown in the diagram) it can be connected to the top of the outer window frame 1 via the rotating connecting assembly 45. There can be two locking members 43, respectively located at both ends of the top of the outer window frame 1 (e.g., Figure 1 (as shown on the left and right ends) to secure and lock the two ends of the handle plate 41 respectively.

[0034] See also Figures 1 to 2 The rotating connecting assembly 45 can be a rotating connecting rod structure, with both ends rotatably connected to the outer window frame 1 via shafts 451. Specifically, the upper left and right sides of the front of the outer window frame 1 are provided with grooves 13, and shafts 451 are installed in both grooves 13. Locking members 43 are rotatably connected to both shafts 451, and the two locking members 43 are respectively engaged with the two sides of the corresponding handle plate 15. The rotating connecting assembly 45 is fixedly connected between the two locking members 43. Figure 1 As shown, during use, the locking parts 43 on both sides are flipped upwards by rotating the connecting assembly 45 to move away from the handle plate 11. Then, the handle plate 11 is dragged by hand and slid up and down on the glass 2. The glass 2 is cleaned by cleaning the cleaning brush 12.

[0035] See also Figure 2The guide self-locking assembly 44 includes a slide groove 441 and a slide plate 442. Each side panel of the outer window frame 1 has a slide groove 441 arranged along the height direction. Each slide groove 441 contains a slide plate 442, which is slidably disposed within the slide groove 441. The two ends of the handle plate 41 are respectively connected to the two slide plates 442 to guide the sliding of the handle plate 41. Specifically, each side of the glass 2 on the outer window frame 1 has a slide groove 441, and each slide groove 441 is slidably connected to a slider 442. The tops of the two sliders 442 are respectively fixedly connected to the left and right rear ends of the handle plate 41. By adding corresponding slide grooves 441 on both sides of the outer window frame 1, sliders 442 are installed within the slide grooves 441, handle plates 41 are installed on the sliders 442, and cleaning brushes 42 are installed on the handle plates 41. The slide 441 and the slide plate 442 are provided with a friction layer (not shown in the figure) to increase the friction between them, so that the handle plate 41 can stop at its position when it loses external moving force and will not fall directly down, and can be manually slid up and down by a person.

[0036] When the cleaning brush 42 is not in use, it is secured by the locking pieces 43 on both sides. Figure 1 As shown, during use, the locking parts 43 on both sides are flipped upwards through the rotating connecting assembly 45 to move away from the handle plate 41. Then, the handle plate 41 is dragged by hand and slid up and down on the glass 2. The glass 2 is cleaned by the cleaning brush 42. The slider 442 on the handle plate 41 is pressed into the slide groove 441 for easy removal.

[0037] See also Figures 1 to 4 The drainage mechanism 5 includes: a water inlet cover 51 and a lower through pipe 52; wherein, the water inlet cover 51 is disposed on the outside of the outer support body 12 (e.g., Figure 2 (As shown on the left), the water-guiding cover 51 is used to protect the outer wall of the outer support body 12 and to drain rainwater; the outer support body 12 is provided with a drain hole 121, which is connected to the bottom groove 11; the lower pipe 52 is detachably inserted through the water-guiding cover 51, and the lower pipe 52 is detachably connected to the drain hole 121 so that the rainwater in the bottom groove 11 can be discharged through the drain hole 121 and the lower pipe 52.

[0038] Specifically, the outer support body 12 has multiple drainage holes 121 at equal intervals, and each drainage hole 121 communicates with the interior of the bottom groove 3. Each drainage hole 121 has an internal thread. A water-guiding cover 51 is installed on the front side of each drainage hole 121, and multiple through holes 511 are equally spaced on the rear side of the water-guiding cover 51. Each through hole 511 corresponds to a lower through pipe 52 passing through it. The outer rear end of each lower through pipe 52 (e.g., ...) Figure 2The upper right end (as shown) is equipped with an external threaded head 521. The internal threads in the multiple drainage holes 121 are detachably connected to the corresponding external threaded heads 521. Fixing bolts 512 are detachably connected to both sides of the water-guiding cover 51, and two fixing bolts 512 are detachably connected to the two ends of the front bottom of the outer window frame 1. The lower through-pipe 52 has an inverted L-shaped structure, with its horizontal connecting pipe screwed to the drainage hole and its vertical drainage pipe arranged downwards. The through hole 511 can be an inverted L-shaped structure adapted to the lower through-pipe 52, allowing the lower through-pipe 52 to be embedded in the water-guiding cover 51. The inner diameter of the through hole 511 is adapted to the outer diameter of the lower through-pipe 52, and their dimensions are also compatible. Installing the lower through-pipe 52 in the through hole 511 increases drainage without allowing the flowing water to damage the surface of the bottom of the outer window. An internal thread is provided inside the through hole 511 for installation with the lower through pipe 52. The external thread head 8 installed on the lower through pipe 52 is threaded into the internal thread groove 6, which increases the drainage effect of the drill hole 5. In this way, when the drill hole 5 drains water, the water will not remain on the bottom surface of the outer window frame 2, but will be discharged directly from the lower through pipe 7. In order to ensure aesthetics, a retaining cover 11 is installed on the outside of multiple lower through pipes 7 and multiple drill holes 5 by fixing bolts 12. In order to protect the lower through pipes 7, the outer surface of the retaining cover 11 is beveled to prevent water accumulation. The device is simple, easy to construct, and the waterproof effect is significantly increased.

[0039] In this embodiment, the top of the water-guiding cover 51 is provided with a water-guiding arc surface 513, and the front side wall of the water-guiding cover 513 is provided with a water-guiding inclined surface 514, the top edge of which is connected to the water-guiding arc surface 514. Specifically, the water-guiding arc surface 513 and the water-guiding inclined surface 514 provided on the outer surface of the water-guiding cover 51 guide water to prevent water accumulation. The water-guiding arc surface 513 can have rounded corners, and the water-guiding inclined surface 514 can be inclined from top to bottom outwards.

[0040] In summary, the water diversion system for the repurposed exterior window facade provided in this embodiment diverts rainwater from the glass 2 into the bottom groove 11 via the water diversion keel plate 3 on the exterior window frame 1; the glass cleaning mechanism 4 on the exterior window frame 1 cleans the glass 2 by sliding it up and down; and the drainage mechanism 5 drains the rainwater from the bottom groove 11 and protects and diverts rainwater from the external support body 12, preventing water accumulation in the bottom groove 11 and the external support body 12. This system provides waterproofing without damaging the original exterior window, while maintaining the overall aesthetic appearance of the facade. This water diversion system for the repurposed exterior window facade is simple, easy to construct, and facilitates cleaning of the glass facade.

[0041] Furthermore, a water-draining surface 121 is formed by processing the edge of the window bottom frame. For example, the original horizontal surface is processed into a 0.2%-0.3% slope, and holes are drilled on the outside of the bottom frame to form the drainage holes 121. This ensures that residual water in the glass flows into the bottom frame for easy drainage. At a position 15mm above the bottom frame, a 15mm inverted equilateral triangle is made from scrap keel to serve as the water-draining keel plate 3. It is anchored to the inner frame with rivets, which saves costs and provides waterproofing without damaging the original exterior window. The drainage holes 121 and the lower pipe 52 are connected... The threaded connection installation enhances the drainage effect of the drain hole 121, preventing water from remaining on the bottom surface of the outer window frame and allowing it to drain directly from the lower pipe 52. To ensure aesthetics, water-guiding covers 51 are installed on the outside of multiple lower pipes 52 and multiple drain holes 121 using fixing bolts. To protect the lower pipes 52, the outer surface of the water-guiding covers 51 is chamfered to form a water-guiding arc surface 513 and a water-guiding slope 514, preventing water accumulation. The installation is simple, easy to construct, and significantly enhances the waterproofing effect.

[0042] Furthermore, by adding corresponding sliding grooves 441 on both sides of the outer window frame 1, a slider 442 is installed in the sliding groove 441, a handle plate 41 is installed on the slider 442, and a cleaning brush 42 is installed on the handle plate 41. When the cleaning brush 42 is not in use, it is held in place by the locking parts 43 on both sides, i.e., the movable clips. When in use, the locking parts 43 on both sides, i.e., the movable clips, are flipped upwards through the rotating connecting component 45 to move away from the handle plate 41. Then, the cleaning brush 42 can be moved up and down on the glass by hand while dragging the handle plate 41 to clean the glass. Cleaning the glass by the cleaning brush makes it convenient to clean the glass.
