Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of doors and windows, in particular to a door and window with an internal drainage function. Background Art
[0002] Traditional doors and windows generally use a front-facing drainage method. This method causes wind pressure on the front of the doors and windows, making it difficult to drain water from the front. The main reason is that in windy and rainy weather, the wind pressure on the front of the doors and windows causes the drainage holes on the entire door and window to be pushed up by the wind pressure, and the amount of rainwater flowing through the door and window is sharply reduced. This makes it difficult for rainwater in the gap between the window frame and the sash to flow downward, thereby increasing the pressure to leak into the room. If the door and window are not sealed well, it is easy to cause leakage from the door and window. In addition, the traditional method of exposing holes in the window frame makes it easy for debris blown in by wind and rain to block these drainage holes, seriously affecting drainage. At the same time, the setting of these drainage holes also affects the appearance of the window. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, unless otherwise specified, "multiple" means two or more.
[0025] Reference Figures 1 to 4 The door and window with internal drainage function shown in the figure includes a window frame 10 and an opening sash 20. One side of the opening sash 20 is hinged on the window frame 10, and the opening sash 20 opens to the indoor room. A sealing member 30 is provided on the window frame 10, and a slope 31 inclined toward the outdoors is provided on the sealing member 30. After the opening sash 20 is closed relative to the window frame 10, the opening sash 20 can abut against the top of the sealing member 30; a drain pipe 11 is provided at the bottom of the window frame 10, and the drain pipe 11 can receive rainwater discharged by the corresponding slope 31 and discharge it downward.
[0026] The window frame 10 and opening sash 20 are both conventional structures, and their specific coordination is not described in detail in this application. Furthermore, a sealing strip 16 is provided between the inner side of the opening sash 20 and the window frame 10. In fact, a sealing strip 16 is also provided between the outer sides of the two. This design provides triple waterproofing and further enhances drainage capabilities.
[0027] In some possible implementations, in order to reduce the amount of rainwater infiltration from the gap between the opening sash 20 and the window frame 10, in one embodiment of the present application, a water-blocking edge 40 is provided at the bottom of the opening sash 20 and the top of the window frame 10, and the water-blocking edge 40 is provided above the joint between the opening sash 20 and the window frame 10.
[0028] See also Figures 1 to 3 In some possible implementations, to improve the drainage of the entire window, the window frame 10 is provided with an outwardly inclined mounting surface 12 on the side facing the outside. The seal 30 is mounted on the mounting surface 12. A drainage hole 13 is provided at the bottom of the mounting surface 12 of the window frame 10, and the drain pipe 11 is installed in the drainage hole 13. This design ensures that even if rainwater bypasses the seal 30 and leaks inward, the design of the mounting surface 12 allows the rainwater to be collected on the outward side of the window frame 10, which facilitates its discharge through the drain pipe 11 in the drainage hole 13, effectively preventing rainwater leakage.
[0029] In the above-mentioned improved embodiment, in order to better drain water, the window frame 10 is provided with a water collection area 14 at the bottom of the mounting slope 12, and the drainage hole 13 is provided in the water collection area 14. Such a design enables rainwater entering the outer surface of the seal 30 to quickly flow downward into the drainage hole 13.
[0030] See also Figure 3 To better enable infiltrating rainwater to flow quickly into the water collection area 14, in one embodiment of the present application, a limit stop edge 15 is provided on the outward side of the window frame 10. A sealing strip 16 is provided on the limit stop edge 15, and a limit sealing plate 21 is provided on the outer periphery of the opening sash 20. When the opening sash 20 is closed relative to the window frame 10, the limit sealing plate 21 can abut against the sealing strip 16 and be located above the bottom of the mounting slope 12. This design ensures that when rainwater infiltrates between the sealing strip 16 and the limit sealing plate 21 and forms droplets that fall, the falling droplets or streams can directly fall onto the bottom of the mounting slope 12, allowing the rainwater to flow more quickly into the water collection area 14 and be discharged through the drain pipe 11.
[0031] In some possible implementations, in order to facilitate better drainage from the lower end of the drain pipe 11, in one embodiment of the present application, a drainage gap 18 is provided on the outdoor side of the bottom of the window frame 10, and the lower end of the drain pipe 11 is provided above the drainage gap 18. Such a design can avoid wind pressure blowing directly from the drainage end of the drain pipe 11, causing rainwater to flow back, thereby reducing the impact of wind pressure.
[0032] See also Figure 3 and Figure 4 In one embodiment of the present application, in order to improve drainage while maintaining a certain degree of sealing, the sealing member 30 includes a mounting portion 32 and a sealing elastic portion 33. The mounting portion 32 is clipped into the slot of the mounting bevel 12. The sealing elastic portion 33 is disposed on the side of the mounting portion 32 away from the mounting bevel 12. The side of the sealing elastic portion 33 away from the outdoor portion can abut against the side of the opening sash 20. The slope 31 is disposed on the side of the mounting portion 32 closer to the outdoor portion, extending to the top of the sealing elastic portion 33. The slope 31 is preferably greater than the slope of the mounting bevel 12. This design ensures that even if rainwater seeps through the gap between the sealing strip 16 and the limiting sealing plate 21 and forms water droplets, even if the rainwater drips toward the indoor side, it can be received by the slope 31 and directed into the water collection area 14. The top of the sealing elastic portion 33 can abut against the side surface of the opening fan 20, so that the sealing of the middle layer can be achieved and the sealing effect can be improved.
[0033] In some possible implementations, to further enhance the sealing effect, an elastic hook 34 is provided on the side of the sealing elastic portion 33 facing away from the outside. The elastic hook 34 is capable of abutting against the side of the sealing baffle 22 on the corresponding side of the opening sash 20. The elastic hook 34 is primarily designed to enhance the seal between the sealing baffle 22 and the sealing elastic portion 33 by virtue of its deformation, thereby preventing the sealing elastic portion 33 from being subjected to excessive deformation, which could lead to excessive deformation of the mounting portion 32 and, in turn, deformation of the slope 31, which could result in rainwater infiltration.
[0034] In some possible implementations, to prevent rainwater from seeping into the interior of the window along the outer periphery of the mounting portion 32, in one embodiment of the present application, the bottom of the mounting portion 32 is adapted to fit within the mounting slope 12, and a limit baffle 17 is provided on the window frame 10. The limit baffle 17 abuts against the side of the mounting portion 32 facing away from the exterior. The top of the limit baffle 17 is higher than the top of the mounting slope 12 and at least half the height of the mounting portion 32. This ensures that even if rainwater in the water collection area 14 overflows the top of the mounting slope 12, it will not seep or flow into the interior of the window.
[0035] The present door and window with internal drainage is designed with an internal seal 30 based on the existing window frame 10 and opening sash 20. The seal 30 is provided with a slope 31 inclined toward the outside, which effectively allows rainwater that enters between the window frame 10 and the opening sash 20 to flow along the slope 31 into the drain pipe 11 on the window frame 10, thereby ensuring smooth drainage. In addition, the downward design of the drain pipe prevents drainage from being affected by frontal wind pressure, thereby improving drainage efficiency.
[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
