The utility model includes a window frame with a glass window on its inner wall and a drainage mechanism on its inner wall. The utility model uses a filter screen to filter rainwater, preventing impurities in the rainwater from clogging the drain outlet. The rainwater then flows outward through the drain pipe. When it comes into contact with a one-way windbreak, the impact force of the rainwater pushes the one-way windbreak open, allowing the water to drain outward. In windy weather, the one-way windbreak seals the drain pipe to prevent strong winds from entering and causing rainwater backflow. This achieves the effect of filtering rainwater while preventing backflow, keeping the indoor environment dry and clean, and avoiding problems such as slippery floors and damp furniture caused by rainwater entering the room, providing residents with a more comfortable and safe living environment.

Description

Technical Field

[0001] This utility model belongs to the field of building door and window technology, and in particular relates to a hidden drainage structure with internal circulation in doors and windows. Background Technology

[0002] In the development of building doors and windows, the design of drainage structure has always been one of the key aspects. With the continuous advancement of building technology and people's increasing demands for living quality;

[0003] According to the published patent CN215671923U, a hidden drainage structure for doors and windows with internal circulation includes a window frame, a mullion, and a window sash. The mullion has a water-guiding cavity on its outer side, and a set of drainage holes on the mullion's water-guiding cavity. The window sash also has a water-guiding cavity on its outer side of the lower frame, and a set of drainage holes on the window sash's water-guiding cavity. The lower frame of the window frame also has a water-guiding cavity on its outer side, and a set of drainage holes on the window frame's water-guiding cavity. This design solves the problem that existing ordinary doors and windows often have drainage holes on the outdoor side. In cases of heavy rain on the outdoor side, the air pressure decreases. According to Le Chatelier's principle, when water flows out through the window frame, the air pressure decreases, causing air to overflow and resulting in poor drainage. However, it still has the following shortcomings:

[0004] The aforementioned equipment, when completed, achieved the effect of smooth drainage even under extreme weather conditions. However, in extreme weather, strong winds may blow rainwater back into the window frame through the drain outlet, causing rainwater backflow. This rainwater may seep into the wall through the gaps between the door / window and the wall, causing the wall to become damp. Long-term dampness can lead to paint peeling and wallpaper mold growth on the wall surface, affecting the interior aesthetics. At the same time, the accumulation of moisture in the wall will also reduce the wall's thermal insulation performance and increase energy consumption. Therefore, we propose an internal circulation concealed drainage structure for doors and windows. Utility Model Content

[0005] The purpose of this utility model is to provide a hidden drainage structure for internal circulation in doors and windows. Through the drainage mechanism and quick-release mechanism, it solves the problem that while the above-mentioned equipment can still achieve smooth drainage under extreme weather conditions, strong winds may blow rainwater back into the window frame through the drainage outlet, causing rainwater backflow. This rainwater may also seep into the wall through the gaps between the door / window and the wall, causing the wall to become damp. Long-term dampness can lead to paint peeling and wallpaper mold growth on the wall surface, affecting the aesthetics of the interior. At the same time, the accumulation of moisture in the wall will also reduce the thermal insulation performance of the wall and increase energy consumption.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a hidden drainage structure with internal circulation in doors and windows, including a window frame, a glass window provided on the inner wall of the window frame, and a drainage mechanism provided on the inner wall of the window frame.

[0008] The drainage mechanism includes several drain outlets, all of which are located on the inner wall of the window frame. Each drain outlet has a slidably connected drainage channel on its inner wall. Each drainage channel has a fixedly connected filter screen on its inner wall. Each drainage channel has a fixedly connected outlet pipe on its bottom outer wall. The inner wall of the window frame has a drainage groove. Each outlet pipe has a fixedly connected fixing plate on its outer wall. Each fixing plate has a rotatably connected rotating shaft on its inner wall. Each rotating shaft has a fixedly connected one-way windbreak plate on its outer wall. The outer wall of the one-way windbreak plate contacts the outer wall of the outlet pipe. The outer wall of the outlet pipe is equipped with a quick-release mechanism.

[0009] Furthermore, the quick-release mechanism includes several connecting blocks, the outer walls of which are fixedly connected to the outer wall of the water outlet pipe, and the inner wall of the window frame is provided with several connecting grooves, the inner walls of which are inserted into the outer walls of the connecting blocks.

[0010] Furthermore, the inner walls of several of the connecting blocks are provided with cross grooves, and the inner walls of several of the connecting blocks are threaded with lead screws.

[0011] Furthermore, a fixing block is rotatably connected to the outer wall of each of the lead screws, and a limit plate is fixedly connected to the inner wall of each of the cross grooves.

[0012] Furthermore, the inner walls of several of the limiting plates are slidably connected to fixed shafts, and the outer walls of several of the fixed shafts are fixedly connected to connecting plates.

[0013] Furthermore, springs are fitted on the outer walls of several of the fixed shafts, and compression blocks are fixedly connected to the outer walls of the ends of several of the fixed shafts near the fixed blocks.

[0014] Furthermore, each of the fixed shafts has a locking block fixedly connected to the outer wall of the end away from the extrusion block, and each of the connecting blocks has a sliding groove on its inner wall.

[0015] Furthermore, the inner walls of several of the sliding grooves are slidably connected to the outer walls of the locking blocks, and the outer walls of several of the locking blocks are engaged with the inner walls of the window frame.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a filter screen, which filters rainwater to prevent impurities from clogging the drain outlet. The rainwater then flows outward through the drain pipe. Upon contact with the one-way windbreak, the impact force of the rainwater pushes the windbreak open, allowing the water to drain outward. In windy weather, the one-way windbreak seals the drain pipe to prevent strong winds from entering and causing backflow of rainwater. This achieves the effect of filtering rainwater while preventing backflow, keeping the indoor environment dry and clean, and avoiding problems such as slippery floors and damp furniture caused by rainwater entering the room. It provides residents with a more comfortable and safe living environment.

[0018] 2. This utility model incorporates a fixing block. When the fixing block moves a certain distance, it stops pressing on the squeezing block. At this point, the spring that was originally squeezed by the squeezing block is released. The spring's rebound force then drives the fixing shaft to quickly reset. When the fixing shaft returns to its original position, it drives the locking block to reset as well. The locking block then disengages from the window frame, and the connecting block is no longer restricted. This achieves the effect of quick disassembly of the water outlet pipe and drainage channel. It allows workers to easily remove damaged parts and replace them with new ones without disassembling the entire door and window or performing complex operations, improving maintenance efficiency and reducing the impact on the normal use of doors and windows.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 As shown, this utility model is a hidden drainage structure for internal circulation in doors and windows, including a window frame 1. A glass window 101 is provided on the inner wall of the window frame 1, which supports and fixes the glass window 101. A drainage mechanism 2 is provided on the inner wall of the window frame 1, including several drainage outlets 201. These outlets 201 are all located on the inner wall of the window frame 1. Rainwater adhering to the glass window 101 is discharged outwards through the drainage outlets 201. The inner walls of the drainage outlets 201 are slidably connected to... The drainage channel 202 has a filter screen 203 fixedly connected to its inner wall. Rainwater enters the drainage channel 202 through the drain outlet 201 and is then filtered by the filter screen 203. The bottom outer wall of the drainage channel 202 is fixedly connected to the outlet pipe 204. The inner wall of the window frame 1 is provided with a drainage groove 205. After filtration, the rainwater is discharged outward through the outlet pipe 204. The drainage groove 205 is used to conceal the drainage channel 202 and the outlet pipe 204. To make it more aesthetically pleasing, a fixing plate 206 is fixedly connected to the outer wall of several water outlet pipes 204, a rotating shaft 207 is rotatably connected to the inner wall of several fixing plates 206, and a one-way wind baffle 208 is fixedly connected to the outer wall of several rotating shafts 207. The one-way wind baffle 208 is used to block the wind from the outside and prevent rainwater from flowing back in. The outer wall of the one-way wind baffle 208 is in contact with the outer wall of the water outlet pipe 204, and the outer wall of the water outlet pipe 204 is provided with a quick-release mechanism 3.

[0030] The quick-release mechanism 3 includes several connecting blocks 301, the outer walls of which are fixedly connected to the outer wall of the water outlet pipe 204. The inner wall of the window frame 1 has several connecting grooves 302. When installing the connecting blocks 301, the operator only needs to align the connecting blocks 301 with the connecting grooves 302. The inner walls of the connecting grooves 302 are inserted into the outer walls of the connecting blocks 301. The inner walls of the connecting blocks 301 each have cross grooves 303, and the inner walls of the connecting blocks 301 are threaded with threaded rods 304. The outer wall of 04 is rotatably connected to a fixing block 305. The rotation of the lead screw 304 drives the fixing block 305 to move downward. At this time, the fixing block 305 will squeeze the parts used later. The inner wall of several cross grooves 303 is fixedly connected to a limiting plate 310. The inner wall of several limiting plates 310 is slidably connected to a fixing shaft 307. The limiting plate 310 is used to support and limit the fixing shaft 307 to prevent the fixing shaft 307 from falling during use. The outer wall of several fixing shafts 307 is fixedly connected to a connecting plate 308.

[0031] A spring 309 is fitted on the outer wall of several fixed shafts 307. The spring 309 is used to quickly reset the fixed shaft 307 after it moves. A pressing block 306 is fixedly connected to the outer wall of the end of several fixed shafts 307 near the fixed block 305. When the fixed block 305 moves downward, it presses the pressing block 306. When the pressing block 306 is pressed, it will drive the fixed shaft 307 to move to both sides. A locking block 311 is fixedly connected to the outer wall of the end of several fixed shafts 307 away from the pressing block 306. A sliding groove 312 is opened on the inner wall of several connecting blocks 301. After the pressing block 306 drives the fixed shaft 307 to move outward, it will drive the locking block 311 to slide in the sliding groove 312. The inner wall of several sliding grooves 312 is slidably connected to the outer wall of the locking block 311. The outer wall of several locking blocks 311 is engaged with the inner wall of the window frame 1.

[0032] One specific application of this embodiment is:

[0033] When staff need to use the equipment, rainwater adhering to the glass window 101 will flow into the window frame 1, and then enter the drainage channel 202 through the drain outlet 201. Upon entering the drainage channel 202, the rainwater will first come into contact with the filter screen 203, which will filter the rainwater and prevent impurities from clogging the drain outlet 201. The rainwater will then fall outwards through the outlet pipe 204. When it comes into contact with the one-way wind deflector 208, the impact of the rainwater will push the one-way wind deflector 208 outwards, allowing the water to drain outwards. In windy weather, the one-way wind deflector 208 will seal the outlet pipe 204 to prevent strong winds from entering. 4. If rainwater backflow occurs and the outlet pipe 204 needs to be replaced, first rotate the screw 304. When the screw 304 starts to rotate, it will drive the fixing block 305 to move upward. When the fixing block 305 moves to a certain distance, it will stop pressing the pressing block 306. At this time, the spring 309, which was originally pressed by the pressing block 306, will be released. The rebound force of the spring 309 will drive the fixing shaft 307 to quickly reset. When the fixing shaft 307 returns to its original position, it will drive the locking block 311 to reset as well. At this time, the locking block 311 will disengage from the window frame 1. At this time, the connecting block 301 will no longer be restricted. The connecting block 301 can then be removed from the connecting groove 302 for replacement.
