Description

Technical Field

[0001] This application relates to the technical field of window sills, and in particular to a waterproof and seepage-proof structure for window sills. Background Technology

[0002] A windowsill is the flat surface that supports a window frame. A well-designed windowsill makes it more aesthetically pleasing. The function of a windowsill is to drain rainwater that runs along the window surface, preventing it from seeping into the wall and into the room through window gaps, while also preventing rainwater from staining the exterior walls.

[0003] During rainy weather, window sills inevitably leak, primarily in two ways: 1. Rainwater seeps in through the gaps between the window sill and the window frame; 2. Rainwater seeps in through the gaps between the window frame and the window. To address these issues, a current type of window sill (as shown in the attached image)... Figure 1 As shown), its outer surface usually has a certain slope, and its interior is provided with a drainage hole 14. The two ends of the drainage hole 14 are respectively connected to the inner surface of the windowsill 1 and the outer surface of the windowsill 1, so that the rainwater on the windowsill 1 can be discharged to the outside in time, thereby improving the waterproof and seepage-proof effect of the windowsill 1.

[0004] However, the existing window sills still have the following problems when in use: 1. Rainwater on the window sill is easily affected by wind and flows back to pollute the exterior wall; 2. The drain hole is easily blocked, which affects the waterproof and seepage prevention effect of the window sill.

[0005] In view of the above situation, there is an urgent need for a window sill structure that has good waterproof and seepage prevention effects and can solve the above problems. Summary of the Invention

[0006] This application provides a waterproof and seepage-proof structure for windowsills, which can reduce the probability of backflow when rainwater is discharged, and at the same time reduce the probability of blockage inside the drain hole, thereby improving the waterproof and seepage-proof effect of the windowsill.

[0007] This application provides a waterproof and seepage-proof structure for a windowsill, employing the following technical solution:

[0008] A waterproof and seepage-proof window sill structure includes a window sill, several anti-clogging components, and a water guide plate. The window sill includes an interior section, an installation section, and an exterior section. The installation section is for mounting a window frame, and the interior section and the exterior section are located on opposite sides of the installation section. Several drainage holes are formed inside the window sill, with one end of each drainage hole penetrating the surface of the interior section and the other end leading to the exterior section. A movable groove adapted to the water guide plate is formed on the exterior section, with both ends penetrating the top and bottom of the exterior section. The end of each drainage hole away from the interior section communicates with the movable groove. The water guide plate is movably connected to the exterior section. When the water guide plate moves downward to its limit position, it blocks the drainage holes, and the bottom of the water guide plate is located below the exterior section. When the water guide plate moves upward to its limit position, the drainage holes communicate with the movable groove. The anti-clogging components include a spiral-shaped guide element disposed in the drainage holes, which guides rainwater to flow out along a spiral trajectory.

[0009] By adopting the above technical solution, when the water guide plate moves downward to its limit position, the bottom of the water guide plate can block rainwater discharged from the top surface of the exterior, reducing the possibility of rainwater backflow and contaminating the exterior wall. At this time, the water guide plate seals the drain hole, reducing the entry of impurities into the drain hole and thus reducing the probability of blockage. When the water guide plate moves upward to its limit position, it reduces the probability of rainwater on the exterior coming into contact with the window frame and reduces the probability of rainwater seeping into the gap between the window frame and the windowsill. At the same time, the water guide plate connects the drain hole to the movable groove, facilitating the timely discharge of rainwater from the top surface of the interior. During the discharge of rainwater through the drain hole, the guide component guides the rainwater to flow out along a spiral trajectory, allowing impurities mixed in the rainwater to be distributed more evenly in the drain hole, reducing the probability of impurities accumulating in the drain hole and causing blockage, thereby improving the waterproof and seepage-proof effect of the windowsill.

[0010] Optionally, the anti-blocking component further includes a control element connected to one end of the flow guide near the interior of the room. The flow guide is rotatably connected to the windowsill, and the rotation axis of the flow guide coincides with its own spiral center line.

[0011] By adopting the above technical solution, when the drain hole becomes blocked, the user can control the flow guide to rotate through the control component to loosen the impurities blocking the drain hole, making it easier for them to flow out with the rainwater. At the same time, by controlling the flow guide to rotate in different directions for a certain period of time, the impurities can also be sent out from both ends of the drain hole, which is convenient for cleaning the impurities and thus reduces the impact of drain hole blockage on the waterproof and seepage-proof effect of the windowsill.

[0012] Optionally, a collection trough is also provided on the interior, the end of the drain hole near the interior is connected to the collection trough, and the control component is located in the collection trough;

[0013] It also includes a filter plate for covering the opening of the collection trough, the filter plate being detachably connected to the interior of the chamber.

[0014] By adopting the above technical solution, the user can control the rotation of the guide to clear the impurities in the drain hole into the collection tank, which is convenient for the user to carry out subsequent treatment of the impurities indoors; the filter plate has a preliminary filtering effect on the rainwater entering the collection tank and the drain hole, thereby further reducing the probability of the drain hole being blocked by impurities.

[0015] Optionally, it also includes two water collection frames, which are located on both sides of the outdoor area. Each water collection frame has a water collection trough, and the end of the water collection frame away from the indoor area is provided with several drainage holes, which are connected to the water collection trough.

[0016] By adopting the above technical solution, rainwater flowing away from both sides of the exterior will fall into the water collection trough of the water collection frame and be collected. The rainwater in the water collection trough can be discharged away from the exterior wall through the drain hole, thereby further reducing the probability of rainwater discharge from the exterior causing pollution to the exterior wall.

[0017] Optionally, it also includes several elastic elements, the water collection frame is slidably connected to the outside of the room, the two ends of the elastic elements are respectively connected to the water collection frame and the outside of the room, and the elastic elements drive the water collection frame to slide upward;

[0018] The sliding of the water collection frame causes the water guide plate to move. When the water collection frame slides upward to its limit position, the water guide plate moves downward to its limit position; when the water collection frame slides downward to its limit position, the water guide plate moves upward to its limit position.

[0019] By adopting the above technical solution, when the rainfall is light, the rainwater in the collection trough can be discharged in time through the drainage hole, keeping the collection trough in the position where it slides upward to its limit. At this time, the guide plate prevents the rainwater from flowing back. When the rainfall is heavy, the rainwater in the collection trough cannot be discharged in time through the drainage hole. At this time, the weight of the collection frame and the rainwater in the collection trough together overcomes the force of the elastic element, causing the collection frame to slide downward to its limit. At this time, the guide plate reduces the probability of rainwater on the outside coming into contact with the window frame. Thus, the guide plate can move according to the rainfall situation and achieve the appropriate effect.

[0020] Optionally, the drain hole is opened at an angle, and the end of the drain hole near the outside of the room is the lower angle.

[0021] By adopting the above technical solution, rainwater can be easily discharged through the drainage holes, the flow rate of rainwater can be accelerated, and rainwater can be discharged in a timely manner, thereby reducing the probability of rainwater seeping into the room.

[0022] Optionally, when the water guide plate moves downward to its limit position, the bottom of the water guide plate is closer to the outside of the chamber and away from the mounting part; when the water guide plate moves upward to its limit position, the top of the water guide plate is closer to the outside of the chamber and away from the mounting part.

[0023] By adopting the above technical solution, when the water guide plate moves downward to its extreme position, the bottom of the water guide plate not only blocks rainwater but also guides it, directing the blocked rainwater to flow away from the exterior wall; when the water guide plate moves upward to its extreme position, the top of the water guide plate not only prevents rainwater from contacting the window frame but also reduces the probability of rainwater splashing onto the outside and seeping in through the gaps between the window frame and the window.

[0024] Optionally, the bottom of the outdoor unit has a blocking member located on the side of the movable groove opposite to the mounting part.

[0025] By adopting the above technical solution, when rainwater flows out from the interior through the drain hole and the movable channel, the blocking component can reduce the impact of wind on the outflowing rainwater, thereby reducing the probability of rainwater polluting the exterior wall after flowing out; at the same time, when rainwater flows out from the exterior away from the installation part, the blocking component can also guide the rainwater to flow away from the exterior wall, thereby further reducing the probability of rainwater polluting the exterior wall after flowing out.

[0026] Optionally, the top end face of the interior is inclined, and the inclination direction of the top end face of the interior is opposite to the inclination direction of the top end face of the exterior.

[0027] By adopting the above technical solution, after rainwater seeps into the interior through the gap between the window and the window frame, the rainwater can flow along the top surface of the interior towards a position away from the window frame. This facilitates the rainwater discharge through the drain hole and further reduces the probability of rainwater contacting the window frame, thereby reducing the probability of rainwater leakage through the gap between the window frame and the windowsill.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. It can reduce the probability of rainwater backflow during drainage, thereby reducing the probability of rainwater contaminating the exterior wall after drainage, and thus improving the waterproof and seepage-proof effect of the windowsill;

[0030] 2. It can reduce the amount of impurities entering the drain hole, thereby reducing the probability of blockage inside the drain hole;

[0031] 3. When the drain hole is blocked by impurities, it can be easily cleared by the user to remove the blockage and facilitate subsequent cleaning, thereby reducing the impact of the blockage on the drainage effect of the windowsill;

[0032] 4. It can reduce direct contact between rainwater and the window frame, and reduce the probability of rainwater leakage through the gap between the window frame and the windowsill;

[0033] 5. It can suppress the splashing of rainwater onto the outside, thereby reducing the probability of rainwater splashing onto the window and causing rainwater to seep in through the gap between the window and the window frame. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0042] Reference Figure 2 This application discloses a waterproof and seepage-proof structure for windowsills, which reduces rainwater infiltration into the room, allows rainwater falling on the windowsill 1 to be discharged to the outside in a timely manner, and prevents rainwater from flowing back and polluting the exterior wall when it is discharged, thus keeping the exterior wall clean.

[0043] The waterproof and seepage-proof structure of the window sill includes the window sill 1, the water guide plate 2, and several anti-clogging components 3.

[0044] Reference Figure 2 and Figure 3 The windowsill 1 is fixedly installed at the bottom of the window, and the window frame 4 and several windows 5 are installed above the windowsill 1 to fill the rest of the window. In this embodiment, it is preferred that a window frame 4 and two windows 5 are installed above the windowsill 1, and it is preferred that the window frame 4 and the two windows 5 form a sliding window. Since sliding windows are common prior art in this field, they will not be described in detail here.

[0045] The two ends of the window sill 1 are located indoors and outdoors, respectively, and the window sill 1 includes an indoor part 11, a mounting part 12, and an outdoor part 13 from indoors to outdoors. The indoor part 11 and the outdoor part 13 are located indoors and outdoors, respectively, and the mounting part 12 is used for mounting and fixing the bottom of the window frame 4.

[0046] Reference Figure 2 and Figure 4 Both the top end face of the interior 11 and the top end face of the exterior 13 are inclined surfaces. The end of the top end face of the interior 11 closer to the interior is the lower inclined end, and the end of the top end face of the exterior 13 closer to the exterior is the lower inclined end. When rainwater is on the interior 11 or the exterior 13, it will flow along the inclined surfaces in a direction away from the window frame 4.

[0047] The windowsill 1 has several drainage holes 14 inside, with both ends of the drainage holes 14 penetrating the interior 11 and the exterior 13, respectively. Rainwater on the top surface of the interior 11 can flow along the drainage holes 14 to the exterior 13 and be discharged to the outside. In this embodiment, it is preferable that there are two drainage holes 14 on the windowsill 1, and the two drainage holes 14 are located on both sides of the windowsill 1.

[0048] Furthermore, the interior 11 preferably has a collection trough 111 for collecting rainwater. The collection trough 111 opens upwards, and the drain hole 14 near the interior 11 communicates with the collection trough 111. A filter plate 6 can also be detachably connected to the interior 11 to cover the opening of the collection trough 111. The filter plate 6 has several filter holes 61, and filter screens 62 are fixedly installed in each filter hole 61 to filter impurities mixed in with the rainwater and to prevent impurities from entering the collection trough 111. In this embodiment, the filter plate 6 is preferably detachably connected to the interior 11 by an embedded cover. In other embodiments, a bolted thread connection can also be used.

[0049] After rainwater seeps into the end face of the top of the interior 11, it will flow along the inclined surface to the filter plate 6, and then pass through several filter holes 61 and several filter screens 62 into the collection tank 111. After the rainwater collected in the collection tank 111 reaches a certain amount, it will be discharged through the drain hole 14.

[0050] Reference Figure 2 and Figure 5 The water guide plate 2 is installed on the exterior 13 and is movably connected to the exterior 13. The exterior 13 has a movable groove 131 adapted to the water guide plate 2. The two ends of the movable groove 131 pass through the top and bottom of the exterior 13, respectively, and the end of the drain hole 14 near the interior 11 communicates with the movable groove 131.

[0051] The water guide plate 2 moves along the movable groove 131, and the movement of the water guide plate 2 is restricted. When the water guide plate 2 moves downward to the limit position, the top end face of the water guide plate 2 is flush with the top end face of the outer chamber 13, and the bottom of the water guide plate 2 is located below the outer chamber 13 and near the end of the outer chamber 13 away from the mounting part 12. At this time, the water guide plate 2 seals the opening of the drain hole 14 near the inner chamber 11. When the water guide plate 2 moves upward to the limit position, the top of the water guide plate 2 will be located above the outer chamber 13 and near the end of the outer chamber 13 near the mounting part 12. At this time, the bottom of the water guide plate 2 will be located above the drain hole 14, so that the drain hole 14 communicates with the movable groove 131.

[0052] Furthermore, in this embodiment, the water guide plate 2 is preferably an arc-shaped plate, and the arc-shaped opening of the water guide plate 2 faces the outside. When the water guide plate 2 slides downward to its limit position, the rainwater on the outside 13 flows out and falls to the outside. The water guide plate 2 can prevent the rainwater from flowing back due to the wind and polluting the exterior wall. At the same time, the rainwater blocked by the water guide plate 2 can also flow out along the arc-shaped surface of the water guide plate 2 in a direction away from the exterior wall. When the water guide plate 2 slides upward to its limit position, the top of the water guide plate 2 contacts the window frame 4 and is located above the window frame 4. This can reduce the amount of rainwater flowing towards the window frame 4 after falling on the outside 13 and contacting the window frame 4. At the same time, it can suppress the degree of splashing of rainwater on the outside 13 and reduce the probability of rainwater splashing onto the window 5 and seeping into the room through the gap between the window 5 and the window frame 4.

[0053] Furthermore, the bottom of the exterior 13 preferably has a blocking member 132, and the blocking member 132 is located at the end of the exterior 13 away from the mounting part 12. When the water guide plate 2 slides downward to its limit position, the arc-shaped surface at the bottom of the water guide plate 2 abuts against the end face of the blocking member 132, and the rainwater flowing down from the exterior 13 can flow through the blocking member 132 to the bottom of the guide plate; when the water guide plate 2 slides upward to its limit position, the rainwater flowing down from the exterior 13 can flow out in a direction away from the exterior wall through the blocking member 132, and at the same time, the blocking member 132 can reduce the impact of wind on the rainwater flowing out from the drain hole 14, thereby further reducing the probability of rainwater backflow and contaminating the exterior wall.

[0054] The anti-clogging component 3 corresponds one-to-one with the drain hole 14, and is used to reduce the probability of the drain hole 14 being blocked by impurities. Therefore, in this embodiment, two anti-clogging components 3 are installed on the windowsill 1. The anti-clogging component 3 includes a guide 31, which has a spiral structure. Preferably, the cross-section of the drain hole 14 is circular. The guide 31 is adapted to the drain hole 14, and preferably the drain hole 14 is opened in a straight line. The guide 31 is located in the drain hole 14. When rainwater in the collection tank 111 enters the drain hole 14 and flows out along the drain hole 14, the guide 31 will guide the rainwater to flow along the spiral path in the drain hole 14, thereby reducing the probability of impurities mixed in the rainwater accumulating and blocking the drain hole 14, so that the impurities mixed in the rainwater can be more evenly distributed in the drain hole 14.

[0055] Furthermore, it is preferable that the drain hole 14 is angled, with the end of the drain hole 14 near the exterior 13 being the downward angled end, to facilitate the discharge of rainwater from the collection tank 111 along the drain hole 14 and to accelerate the flow rate of rainwater through the drain hole 14. Also preferably, the upward angled end of the drain hole 14 extends towards the interior and can pass through the opening of the collection tank 111, making it convenient for the user to remove and replace the guide member 31 through the opening of the collection tank 111.

[0056] Furthermore, the flow guide 31 is rotatably connected to the windowsill 1, and the anti-clogging assembly 3 also includes a control component 32 for convenient user control of the rotation of the flow guide 31. The control component 32 is fixedly connected to the end of the flow guide 31 near the interior 11, and the control component 32 is located in the collection tank 111; the rotation axis of the flow guide 31 coincides with the axis of the drain hole 14, and the user can control the rotation of the flow guide 31 relative to the windowsill 1 through the control component 32 after opening the filter plate 6.

[0057] The rotation of the guide member 31 can scrape off impurities adhering to the wall of the drain hole 14, thereby clearing blockages. Furthermore, controlling the rotation of the guide member 31 in different directions can drive the scraped-off impurities in the drain hole 14 towards the collection tank 111 or the movable tank 131, thus removing the impurities from the drain hole 14. When it is necessary to remove impurities from the drain hole 14, it is preferable for the user to control the rotation of the guide member 31 to drive the impurities towards the collection tank 111, facilitating subsequent processing of the impurities in the collection tank 111 and effectively reducing the probability of a large amount of impurities polluting the exterior wall after being discharged from the movable tank 131.

[0058] Reference Figure 3 and Figure 6 Furthermore, the waterproof and seepage-proof structure of the windowsill 1 also includes two water collection frames 7, which are installed on both sides of the exterior 13 to collect rainwater flowing down from both sides of the exterior 13, thereby further reducing the probability of rainwater flowing down and polluting the exterior wall.

[0059] The water collection frame 7 has an upward-opening water collection trough 71. Several drainage holes 72 are provided at the end of the water collection frame 7 away from the exterior wall, and both ends of the drainage holes 72 are connected to the water collection trough 71 and the side of the frame itself away from the exterior wall, respectively. When the rainwater collected in the water collection trough 71 reaches a certain amount, the rainwater can be discharged through the drainage holes 72 in a direction away from the exterior wall, thereby further reducing the probability of rainwater polluting the exterior wall after discharge.

[0060] Furthermore, the water collection frame 7 is preferably slidably connected to the exterior 13, and the sliding direction of the water collection frame 7 is preferably vertical. In addition, the window sill waterproofing and seepage prevention structure preferably includes several elastic elements 8, with both ends of the elastic elements 8 fixedly connected to the water collection frame 7 and the exterior 13, respectively. The elastic elements 8 drive the water collection frame 7 to slide upward relative to the exterior 13. In this embodiment, the elastic element 8 is preferably a compression spring, and preferably one elastic element 8 corresponds to each water collection frame 7.

[0061] The sliding of the water collection frame 7 relative to the outdoor area 13 is restricted, and the sliding of the water collection frame 7 is driven by the amount of rainwater collected in the water collection trough 71. When the liquid level of the rainwater collected in the water collection trough 71 is kept flush with the drain hole 72 (i.e., the rain is light and the rainwater in the rain trough can be discharged in time through the drain hole 72), the water collection frame 7 can slide upward to the limit position under the action of the elastic element 8 and hold there; when the liquid level of the rainwater collected in the water collection trough 71 is higher than the drain hole 72 (i.e., the rain is heavy and the rainwater in the rain trough cannot be discharged in time through the drain hole 72), the water collection frame 7 will overcome the action of the elastic element 8 and slide downward to the limit position under the action of its own weight and the weight of the rainwater in the water collection trough 71.

[0062] Furthermore, it is preferable that the sliding of the water collection frame 7 can drive the water guide plate 2 to move, and preferably when the water collection frame 7 slides upward to the limit position, the water guide plate 2 moves downward to the limit position accordingly; when the water collection frame 7 slides downward to the limit position, the water guide plate 2 moves upward to the limit position accordingly.

[0063] In this embodiment, preferably, both sides of the exterior 13 are equipped with linkage components 9 for linking the water collection frame 7 and the water guide plate 2. The linkage component 9 includes several linkage gears 91. In this embodiment, preferably, the linkage component 9 includes one linkage gear 91, and preferably, the linkage gear 91 is rotatably connected to the exterior 13 with a rotation axis parallel to the length direction of the windowsill 1.

[0064] Preferably, the water collecting frame 7 has a rack structure distributed along the vertical direction, and the water guide plate 2 also has a rack structure distributed along its own arc trajectory direction. The linkage gear 91 is located between the rack structure on the water collecting frame 7 and the rack structure on the water guide plate 2, and both the rack structure on the water collecting frame 7 and the rack structure on the water guide plate 2 mesh with the linkage gear 91.

[0065] When the rainfall is light, it means that less rainwater falls on the exterior 13. At this time, the rainwater on the exterior 13 will drip out in a direction away from the exterior wall. At this time, the wind has a greater impact on the rainwater and the probability of the rainwater on the exterior 13 contacting the window frame 4 is small. Therefore, the water guide plate 2 needs to be moved downward to its limit position so that the bottom of the water guide plate 2 can be used to block the backflow of rainwater and guide the rainwater to flow out in a direction away from the exterior wall, thereby further reducing the probability of rainwater flowing out and polluting the exterior wall.

[0066] When the rain is heavy, it means that a lot of rainwater falls on the outside of the room 13. At this time, the rainwater on the outside of the room 13 will flow out in the direction away from the exterior wall in the form of water flow. Therefore, the blocking member 132 alone is sufficient to suppress the phenomenon of rainwater backflow affected by wind. In addition, at this time, the probability of rainwater splashing onto the window 5 after falling on the outside of the room 13 is high. It is necessary to move the water guide plate 2 upward to the extreme position so that the top of the water guide plate 2 can reduce the contact between rainwater and the window frame 4, and at the same time suppress the splashing of rainwater.

[0067] The implementation principle of a waterproof and seepage-proof window sill structure according to an embodiment of this application is as follows:

[0068] When the rain is light, the rainwater will flow along the inclined surface after falling to the outside 13. Some of the rainwater will flow into the water collection frame 7 for collection, and some of the rainwater will flow out to the outside. The bottom of the water guide plate 2 will block the backflow of rainwater and guide the rainwater to flow away from the exterior wall.

[0069] When the rain is heavy, rainwater will splash after falling onto the outside 13. Some of the rainwater will splash onto the window 5 and seep into the interior 11 through the gap between the window 5 and the window frame 4. The top of the water guide plate 2 can suppress the splashing of rainwater and reduce the amount of rainwater splashing onto the window 5, thereby reducing leakage. The rainwater that seeps into the interior 11 will flow into the collection tank 111 and then be discharged through the drain hole 14. At the same time, some of the rainwater on the outside 13 will flow into the water collection frame 7 for collection, and some will flow out directly, which can reduce the probability of rainwater flowing out and polluting the exterior wall.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
