Description

Technical Field

[0001] This utility model mainly relates to the field of door and window profile technology, specifically a door and window profile with drainage function. Background Technology

[0002] Window and door profiles refer to the materials used to make the core structures of windows and doors, such as frames and sashes. They usually have specific cross-sectional shapes and mechanical properties, and can meet the functional requirements of windows and doors, such as support, sealing, heat insulation, and sound insulation.

[0003] Drainage-functional window and door profiles refer to window and door structural materials that, based on traditional window and door profiles, incorporate special cross-sectional designs (such as pre-reserved drainage channels and flow channels) to guide and drain rainwater, condensation, and other liquids accumulated between the window and door frame and sash, while also maintaining basic performance characteristics such as support, sealing, and heat insulation. Traditional drainage structures are mostly located at the track of the moving sash side of the window frame, focusing only on drainage within the gap between the moving sash and the window frame, often neglecting the drainage needs of the fixed frame section. This leads to water accumulation in the fixed frame area. Furthermore, most of these drainage structures are exposed externally or use windproof panels, which, while blocking some rainwater, cannot actively drain already seeped water. Under strong wind pressure, backflow can easily occur, causing water to stagnate within the profile, leading to problems such as corrosion and deterioration of sealing performance over time. Utility Model Content

[0004] This utility model addresses the problem of overly simplistic existing solutions by providing a door and window profile with drainage functionality. This solves the problem that the drainage structures mentioned in the background technology have significant limitations, focusing only on the sliding track of the window frame and neglecting the drainage needs of the fixed frame. Furthermore, these structures are often exposed or use windproof panels, making them unable to actively drain water. Under strong wind pressure, backflow can easily occur, leading to water accumulation, which in turn causes profile corrosion and seal deterioration.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A door and window profile with drainage function includes a profile with a cavity for installing double-glazed soundproof glass. Sealing strips are fixed inside the profile at the edges of the double-glazed soundproof glass. Support strips for supporting the bottom and top of the double-glazed soundproof glass are fixed inside the mounting cavity of the profile corresponding to the double-glazed soundproof glass. Foam is provided on one side of the outer wall of the profile, and a drainage cover is provided above the foam. The drainage cover is installed on the profile by a limiting buckle.

[0006] Furthermore, the sealing strip is distributed in a continuous enclosing shape along the length of the outer periphery of the insulated glass, and the sealing strip is simultaneously provided on the inner and outer edges of the insulated glass.

[0007] Furthermore, heat insulation strips are installed at the locations where the mounting brackets are installed inside the profile.

[0008] Furthermore, the foam is fixed in the area with a groove on one side of the outer wall of the profile, and the foams are distributed at equal intervals. The surface of the foam is distributed with a through-hole structure, and the micropores are arranged in a discrete or arrayed manner on the surface of the foam.

[0009] Furthermore, the profile has a groove for installing a drain cover above the corresponding foam. The groove is connected to the area where the foam is located. The groove is adapted to the specifications of the foam. The drain cover is distributed along the length of the profile corresponding to the installation position of the foam, and the extension direction of the drain cover is consistent with the arrangement direction of the foam.

[0010] Furthermore, the profile has longitudinal drainage channels at each slot corresponding to the installation of the drainage cover. The extension direction of the drainage channels is perpendicular to the extension direction of the slot, and the drainage channels extend from the first slot to the last slot.

[0011] Furthermore, the drain cover is in the shape of a grid plate, and the limiting buckle is inserted into the hollow area between the grids of the drain cover to limit the displacement of the drain cover in the slot. The bottom of the limiting buckle is an elastic end, which is attached to the bottom of the drain cover and located above the foam.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The drainage structure of this profile, through the organic combination of foam, drainage channels, drainage covers, and limiting buckles, forms an active adsorption-directional flow guidance-directional drainage-water-blocking protection system. The through-hole structure of the foam can actively adsorb the infiltrated water and guide it outward, retaining the blocking function of traditional windbreaks while also buffering wind pressure through its own elasticity, effectively preventing rainwater backflow during extreme weather such as typhoons. The through-hole design of the drainage channels and the grid structure of the drainage covers form a three-dimensional drainage path, which can concentrate and guide scattered water to the foam area, solving the defects of traditional drainage structures that rely on only a single channel and are prone to failure due to local blockage.

[0013] 2. The drainage cover of this profile is concealed within the groove by a flexible fixing method using limiting buckles, achieving an invisible drainage structure. This avoids the problem of traditional exposed drainage components damaging the overall aesthetics of doors and windows. At the same time, the grid structure of the drainage cover ensures smooth water flow while maintaining concealment and preventing blockage. Combined with the full-area through-flow design of the drainage channel, it ensures continuous and efficient drainage from the beginning to the end of the profile, achieving concealment without affecting drainage performance.

[0017] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Please refer to the appendix carefully. Figure 1-6 A door and window profile with drainage function includes a profile 1. The profile 1 has a cavity for installing a double-glazed soundproof glass 2. Sealing strips 3 are fixed in the profile 1 at the edges of the double-glazed soundproof glass 2. Support strips 4 for supporting the bottom and top of the double-glazed soundproof glass 2 are fixed in the mounting cavity of the profile 1 corresponding to the double-glazed soundproof glass 2. Foam 6 is provided on one side of the outer wall of the profile 1. A drainage cover 8 is provided above the foam 6. The drainage cover 8 is installed on the profile 1 by a limiting buckle 9.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the sealing strip 3 is distributed in a continuous enclosing shape along the length of the outer periphery of the hollow soundproof glass 2, and the sealing strip 3 is simultaneously set on the inner edge and the outer edge of the hollow soundproof glass 2.

[0021] With the above structure, when the profile 1 is spliced ​​to form a window frame, the sealing strip 3 is distributed in a continuous enclosed shape along the length of the outer periphery of the hollow soundproof glass 2, and is also set on the inner and outer edges of the glass. This structure can form a three-dimensional protective barrier through double sealing. This continuous enclosed shape can completely eliminate the gap between the glass and the profile 1, block the intrusion path of air, rainwater and dust, and ensure the integrity of the seal.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, heat insulation strips 5 are installed at the positions of the mounting brackets 4 inside the profile 1.

[0023] With the above structure, the heat insulation strip 5 is installed at the position of the mounting strip 4 inside the profile 1. With the help of the low thermal conductivity of the heat insulation strip 5, the heat transfer path inside the profile can be effectively blocked, and the thermal bridge effect formed by the temperature difference between indoor and outdoor through the strip 4 and the main body of the profile can be reduced, thereby improving the overall heat insulation performance of the window frame and reducing the energy exchange loss between indoor and outdoor.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, foam 6 is fixed in the area with a groove on one side of the outer wall of profile 1, and foam 6 is distributed at equal intervals. Furthermore, the surface of foam 6 is distributed with a through-hole structure, and the micropores are arranged in a discrete or arrayed manner on the surface of foam 6.

[0025] Through the above structure, foam 6 achieves stable installation with the help of the external groove of profile 1. The uniformly spaced drainage units ensure that water flow can be dispersed and absorbed, preventing local overload. The interconnected microporous structure on its surface, whether discrete or arrayed, provides ample channels for water penetration, allowing it to quickly absorb surrounding water and drain it outwards. Traditional windbreaks can only reduce the direct intrusion of wind and rain through physical shielding, but in strong winds or typhoons, they are prone to backflow due to wind pressure and cannot handle water that has already seeped into the profile. The microporous structure of foam 6 can actively drain water through adsorption and drainage, preventing internal stagnation, and can also use its own elasticity to buffer wind pressure, reducing the risk of backflow. At the same time, the dispersed distribution can accurately handle the seepage situation in different areas, solving the water accumulation problem caused by the traditional windbreaks that "only block but do not drain", and improving the waterproof and drainage capabilities of profile 1.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 6 As shown, the profile 1 has a groove for installing a drain cover 8 above the foam 6. The groove is connected to the area where the foam 6 is located. The groove is compatible with the specifications of the foam 6. The drain cover 8 is distributed along the length of the profile 1 corresponding to the installation position of the foam 6, and the extension direction of the drain cover 8 is consistent with the arrangement direction of the foam 6.

[0027] Through the above structure, the groove of the drain cover 8, being connected to and sized to match the area where the foam 6 is located, ensures that the water entering the groove is precisely guided to the foam 6, preventing water stagnation. The design of the drain covers 8 being distributed along the length of the profile 1 corresponding to the position of the foam 6 and extending in the same direction ensures that each area of ​​the foam 6 can achieve independent and efficient drainage through the corresponding drain cover 8, and also makes the drainage path precisely correspond to the water absorption area of ​​the foam 6, enhancing the synergy of the drainage system. In addition, it can reduce structural redundancy, ensuring drainage function while taking into account the overall compactness and aesthetics of the profile, effectively improving the drainage stability of the window frame profile in complex environments.

[0028] In this embodiment, as Figure 2 and Figure 3 As shown, the profile 1 has longitudinally extending drainage grooves 7 at each slot corresponding to the installation of the drainage cover 8. The extension direction of the drainage grooves 7 is perpendicular to the extension direction of the slot, and the drainage grooves 7 extend from the first slot to the last slot.

[0029] Through the above structure, the longitudinal drainage channels 7 opened at the corresponding slots of the drainage cover 8 on the profile 1 can form an efficient full-area drainage path because the extension direction is perpendicular to the slot and runs through from the first slot to the last slot. On the one hand, it can concentrate and guide the water scattered around each slot to the drainage channel, avoiding local water seepage into the interior of the profile. On the other hand, the direction perpendicular to the slot and the grid structure of the drainage cover 8 form a three-dimensional drainage system, which accelerates the convergence and discharge of water to the foam 6 area. At the same time, the through-type design ensures the continuity of drainage from the first end to the last end of the profile. Even in the case of multiple slots, the drainage efficiency can be kept consistent, which effectively improves the reliability and anti-clogging ability of the overall drainage system.

[0030] In this embodiment, as Figure 5 and Figure 6 As shown, the drain cover 8 is in the shape of a grid plate, and the limiting buckle 9 is inserted into the hollow area between the grids of the drain cover 8 to limit the displacement of the drain cover 8 in the slot. The bottom of the limiting buckle 9 is an elastic end, which is attached to the bottom of the drain cover 8 and located above the foam 6.

[0031] Through the above structure, the drain cover 8 is inserted into the hollow area of ​​its grid by the limiting buckle 9. This structure can effectively constrain the lateral and longitudinal displacement of the drain cover 8 in the groove through precise mechanical limiting, prevent loosening and detachment, and ensure the integrity of the drainage channel. At the same time, it can provide a smooth path for water flow by utilizing the grid gaps, while filtering larger debris to prevent blockage. The elastic end at the bottom of the limiting buckle 9 makes it easy to insert into the grid area during installation. After insertion, it can be tightly locked into the bottom of the drain cover 8 by elastic reset, and fit tightly with the bottom of the drain cover 8. The pre-tightening force enhances the connection stability, and even if the profile is slightly deformed, the fixing effect can be maintained by elastic compensation.

[0032] The specific operating procedure of this utility model is as follows: The profile 1 serves as the main frame component of the window frame. It can be assembled by splicing multiple profiles to form a complete window frame structure. For example, it can be combined with vertical frame profiles, horizontal connecting profiles, etc., and fixed with connectors to form a closed window frame.

[0033] Window frames are exposed to the external environment, especially near the outside, and are subject to wind and sun exposure for a long time. This can easily cause the sealing strip 3 to age and harden, resulting in gaps in the seal. Rainwater can then seep in through these gaps. At the same time, moisture condensed on the surface of the double-glazed soundproof glass 2 due to the temperature difference between day and night can also seep in through the contact gap between the glass and the sealing strip 3. All of these factors can cause water to leak into the interior of the frame inside the glass mounting cavity.

[0034] The window frame profile has a groove for installing a drainage cover 8 on one side of the glass mounting cavity. The groove is recessed, and with the structure of the drainage channel 7, water entering the profile will flow through the groove to the location of the foam 6. Due to the microporous structure on the surface of the foam 6, the foam 6 can quickly absorb and drain water, and at the same time, it can gradually drain water by utilizing its own water absorption and breathability, thus preventing water from accumulating inside the profile.

[0035] In traditional foam 6 installations, a windbreak is usually installed. However, in strong winds or typhoons, the high wind pressure can easily cause rainwater to backflow. Foam 6, on the other hand, can form a buffer barrier through its elasticity and microporous structure, effectively preventing rainwater from backflowing while ensuring smooth drainage.

[0036] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
