Technical Field
[0001] This utility model relates to the field of inward-opening window technology, and in particular to an inward-opening window with concealed drainage. Background Technology
[0002] An inward-opening window is a window that opens inwards. In some residential communities with small building spacing, bathroom windows are designed as inward-opening windows. This is for safety and to prevent outward-opening windows from blocking light.
[0003] The commonly used inward-opening windows for bathrooms in residential communities are all made of aluminum alloy frames. The window body and the window frame are usually installed with hinges to achieve the effect of inward opening. A groove is usually made in the window frame. When the window is closed, it fits perfectly into the groove, ensuring the overall flatness and aesthetics.
[0004] Currently, existing bathrooms in residential communities use inward-opening windows. Bathrooms have high humidity and a lot of moisture in the air. Drainage holes are usually made in the window frame. However, the drainage efficiency of existing drainage holes is weak, and most of the existing drainage holes are exposed, which is not aesthetically pleasing.
[0005] In addition, steel screens are typically installed on the inward-opening window structures used in restrooms in renovated residential communities. These screens ensure ventilation when the window is closed and prevent insects from entering. However, with prolonged use, due to the constant dampness in the restroom, limescale and soap scum adhere to the mesh of the screen. People often clean these screens with stiff brushes or by inserting fine, hard metal needles into the mesh. Over time, this cleaning process causes the screen to age, become deformed, and require replacement. However, the steel screens on most existing inward-opening window structures in renovated residential community restrooms are not easily replaceable.
[0006] Therefore, we designed a design that replicates the inward-opening window structure used in community bathrooms to meet the needs of practical applications. Utility Model Content
[0007] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a concealed drainage inward-opening window.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] Design a concealed drainage inward-opening window, including a window frame, a hinge on the window frame, a window body connected to the window frame via the hinge, a recessed groove and a drainage groove on the window frame, a guide hole and a drainage hole in the drainage groove, a recessed opening and a finger-locking groove on the window body, a damping frame installed in the recessed opening, a window screen installed in the damping frame, a plug slidably connected in the finger-locking groove, a handle installed on the plug, a spring installed on the handle, and a handle on the window body;
[0010] The window body has a fixed groove, the window screen has a fixed block, and the fixed block has a locking groove;
[0011] The guide hole is provided with a water collection flare, the guide hole is provided with a dirt-proof mesh, and the drain hole is provided with a plug mesh.
[0012] In detail, the guide holes and drainage holes are a set, a total of thirteen arranged horizontally. The guide holes are embedded in the drainage groove, and the drainage holes are opened on the outer back end face of the window frame.
[0013] In detail, the angle between the drain hole and the horizontal plane is 15 degrees, and the flow-through layer is uniformly arranged along the inner wall of the guide hole and the drain hole.
[0014] In detail, the water collection flare is opened at the upper opening of the guide hole, the anti-fouling net is located at the upper opening of the guide hole, and the plug net is located at the opening of the drain hole.
[0015] In detail, the insert is slidably disposed with the window and engages with the locking groove, and the fixed block engages with the fixed groove.
[0016] In detail, the countersunk opening is a rectangular countersunk opening that extends through the window, and the damping frame is evenly distributed along the inner wall of the countersunk opening.
[0017] In detail, the two ends of the spring are fixedly installed to the inner walls of the buckle handle and the finger buckle groove, respectively, and the buckle handle is not higher than the finger buckle groove.
[0018] The design scheme proposed in this utility model has the following beneficial effects in application:
[0019] 1. This utility model, by setting embedded hidden guide holes in the drainage channel and setting hidden inclined drainage holes on the outside, addresses the issue of high humidity in bathrooms where moisture accumulates in the drainage channel. The accumulated moisture is then quickly drained away towards the outside of the window frame through each guide hole and the hidden inclined drainage holes, combined with the set flow-through layer structure. This significantly improves the drainage efficiency of the window frame structure for inward-opening windows in bathrooms. Furthermore, the embedded hidden guide hole structure and the hidden inclined drainage holes prevent the guide holes and drainage holes from being visible from the bathroom, further enhancing the overall aesthetics.
[0020] 2. This utility model, by setting an elastic locking and snap-fit structure between the window body and the window screen, allows for easy replacement of the window screen when it is necessary to replace an aged and deformed screen. The window body is opened first, then the finger is inserted into the snap-fit handle in the snap-fit groove and pulled, causing the insert to slide and exit the locking groove. The aged and deformed screen is then removed, and the new screen can be easily snapped and locked in place later. This improves the ease of replacing the window screen on the inward-opening window structure used in the community bathroom.
[0021] 3. This utility model achieves an integrated recessed snap-fit installation of the window screen by creating a recessed opening structure with a damping frame on the window frame, which greatly improves the overall aesthetic effect of integrating the window screen and the window frame in the inward-opening window structure used in community bathrooms.

Detailed Implementation
[0029] 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.
[0030] Reference Figures 1-6 A concealed drainage inward-opening window includes a window frame 1, a hinge 11 on the window frame 1, a window body 3 connected to the window frame 1 via the hinge 11, a recessed groove 12 and a drainage groove 13 on the window frame 1, a guide hole 2 and a drainage hole 6 in the drainage groove 13, a recessed opening 4 and a finger-fastening groove 7 on the window body 3, a damping frame 41 in the recessed opening 4, a window screen 5 in the damping frame 41, a plug 71 slidably connected in the finger-fastening groove 7, a handle 72 on the plug 71, a spring 73 on the handle 72, and a handle 31 on the window body 3.
[0031] A fixed groove 32 is provided on the window 3, and a fixed block 51 is provided on the window screen 5. A locking groove 52 is provided on the fixed block 51.
[0032] The guide hole 2 is provided with a water collection flare 21, and the guide hole 2 is provided with a dirt-proof net 22. The drainage hole 6 is provided with a plug net 61. The window frame 1, hinge 11, window body 3, and handle 31 are all aluminum alloy inward opening window related structures, which are existing technologies. Some existing structures are not drawn and labeled, so they need not be described in detail. Among them, the window screen 5 is made of steel mesh.
[0033] It should be further explained that the guide hole 2 and the drain hole 6 are a group of thirteen arranged horizontally. The guide hole 2 is embedded in the drain groove 13, and the drain hole 6 is opened on the outer back end face of the window frame 1, so that the water accumulated in the drain groove 13 can be quickly discharged to the outside of the window frame 1, avoiding it from flowing into the bathroom.
[0034] It should be further noted that the angle between the drain hole 6 and the horizontal plane is 15 degrees. The flow-through layer 8 is evenly arranged along the inner wall of the guide hole 2 and the drain hole 6. The flow-through layer 8 is a graphite powder density coating layer with a smooth and durable surface. Combined with the 15-degree inclined drain hole 6, it greatly improves the drainage efficiency.
[0035] It should be further noted that the water collection flare 21 is opened at the upper end of the guide hole 2, which further increases the effective water collection area and thus improves the drainage efficiency.
[0036] The anti-fouling net 22 is located at the upper opening of the guide hole 2. The anti-fouling net 22 is made of stainless steel to ensure drainage and prevent large particles of impurities from entering the guide hole 2.
[0037] The mesh 61 is located at the opening of the drain hole 6. The mesh 61 itself is made of stainless steel, which is corrosion-resistant, oxidation-resistant and durable. It is directly welded into the drain hole 6. At the same time, the mesh 61 has many small holes to achieve the drainage effect. Moreover, the mesh 61 is the same color as the window frame 1, thus achieving the hidden aesthetics of the drain hole 6.
[0038] It should be further explained that the insert 71 is slidably set with the window 3 and engages with the locking groove 52, and the fixing block 51 engages with the fixing groove 32, so as to achieve stable engagement and positioning of the window screen 5.
[0039] It should be further noted that the recessed opening 4 is a rectangular recessed opening that extends through the window 3, ensuring the ventilation effect of the window screen 5 after it is installed.
[0040] The damping frame 41 is evenly arranged along the inner wall of the sink opening 4. The damping frame 41 is made of TPE elastic plastic material. TPE elastic plastic material is environmentally friendly, non-toxic, durable, and has excellent high elasticity and damping friction. During installation, the window screen 5 is first squeezed and inserted into the damping frame 41 to prevent the window screen 5 from slipping out.
[0041] It should be further noted that the two ends of the spring 73 are fixedly installed on the inner wall of the buckle handle 72 and the finger buckle groove 7, respectively. The spring 73 is made of high-quality stainless steel spring steel, which is durable, corrosion-resistant and highly elastic.
[0042] The handle 72 should not be higher than the finger groove 7 to prevent the handle 72 from protruding and affecting the closing of the form 3 into the groove 12.
[0043] Working principle: Due to the high humidity in the bathroom and the presence of a lot of moisture in the ambient air, the water accumulates in the drain trough 13. The accumulated water then flows through each guide hole 2 and the externally concealed inclined drain hole 6. Combined with the set flow-through layer 8 structure, the accumulated water is quickly drained away from the outside of the window frame 1, which greatly improves the drainage efficiency of the window frame 1, which restores the inward opening window structure used in the community bathroom. Moreover, the embedded concealed guide hole 2 structure and the externally concealed inclined drain hole 6 prevent the guide hole 2 and drain hole 6 from being seen from the bathroom, further improving the overall aesthetics.
[0044] Furthermore, when it is necessary to replace the aged and deformed window screen 5, first open the window 3, then insert your finger into the latch 72 in the latch groove 7 and pull it to make the insert 71 slide and exit the locking groove 52. Then take out the aged and deformed window screen 5. Later, the new window screen 5 can be easily snapped and locked, which improves the ease of replacement of the window screen 5 on the inward opening window structure of the community bathroom.
[0045] In addition, by pulling the handle 72 outward, the insert 71 slides outward and retracts into the preset sliding position on the window 3. At this time, the spring 73 stretches and deforms, and then the window screen 5 is squeezed and inserted into the damping frame 41 of the recessed opening 4. Then, the handle 72 is released, the spring 73 rebounds, and the insert 71 is quickly snapped into the fixed groove 32 of the fixed block 51 on the window screen 5, thus realizing the convenient installation of the window screen 5. At this time, the window screen 5 is installed as a whole in a recessed snap-fit, which greatly improves the overall aesthetic effect of the window screen 5 and the window 3 on the inward opening window structure of the community bathroom.
[0046] 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.
