Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a door and window with waterproof function. Background Technology

[0002] With the continuous development of the construction industry, people have increasingly higher requirements for the performance of doors and windows. Waterproofing performance, as one of the important performance indicators of doors and windows, directly affects the comfort of the indoor environment and the service life of buildings. There are many waterproofing problems in existing door and window structures. For example, gaps between the door / window frame and the wall can easily become channels for rainwater infiltration, and traditional sealing methods are often insufficient to effectively block rainwater for a long time; at the overlap between the door / window sash and the frame, rainwater can easily enter the room through gaps during heavy rain; in addition, an unreasonable drainage system design can lead to rainwater accumulation and inability to drain in time, thus increasing the risk of rainwater leakage.

[0003] Currently, although there are some waterproof door and window products on the market, most of them suffer from problems such as complex structure, high cost, and inconvenient installation and maintenance. For example, some doors and windows achieve waterproofing by adding multiple layers of sealing strips, which not only increases manufacturing costs but also makes opening and closing the doors and windows difficult. Other doors and windows use special drainage structures, but these structures are easily clogged by dust and debris during actual use, leading to poor drainage and a significant reduction in waterproofing effectiveness. Therefore, it is necessary to design a door and window with waterproof functionality. Summary of the Invention

[0029] Please see Figures 1-3 This utility model discloses a waterproof door and window, including a door and window frame 1, a door and window sash 2, a sealing component and a drainage component;

[0030] The door / window frame 1 includes an outer frame 3 and an inner frame 4. The outer frame 3 is used to connect to the wall. An outwardly protruding mounting flange 17 is provided on the outer side wall of the outer frame 3, and multiple mounting holes 18 are provided on the mounting flange 17. The inner frame 4 is located inside the outer frame 3, forming a cavity between the outer frame 3 and the inner frame 4. Waterproof sealant is filled between the outer frame 3 and the wall to further enhance the sealing between the door / window frame and the wall, preventing rainwater from seeping in through the gaps between the door / window frame and the wall. A first groove 5 is provided on the inner side wall of the outer frame 3, and a first protrusion 6 matching the first groove 5 is provided on the outer side wall of the inner frame 4. The first protrusion 6 is embedded in the first groove 5. A shock-absorbing pad 7 is also provided between the outer frame 3 and the inner frame 4. The shock-absorbing pad is made of an elastic material, such as rubber, which can effectively reduce the vibration and noise generated when the door / window is closed, while also enhancing the sealing between the outer frame and the inner frame.

[0031] The door and window sash 2 is located on the inside of the door and window frame. The door and window sash 2 is connected to the inner frame 4 by a hinge or hinge 8. The outer edge of the door and window sash 2 is provided with a second groove 9. The inner side wall of the inner frame 4 is provided with a second protrusion 10 that matches the second groove 9. When the door and window sash is closed, the second protrusion is embedded in the second groove to form the first waterproof barrier.

[0032] The sealing assembly includes a first sealing strip 11 and a second sealing strip 12. The first sealing strip 11 is disposed at the bottom of the second groove 9, and the second sealing strip 12 is disposed on the inner sidewall of the inner frame 4, located inside the second protrusion 10. The first sealing strip is made of EPDM material, which has good weather resistance, aging resistance, and sealing performance. When the door and window sash is closed, the first sealing strip fits tightly against the second protrusion, further enhancing the sealing between the door and window sash and the inner frame, preventing rainwater from seeping in through the gaps between the door and window sash and the inner frame.

[0033] A third sealing strip is provided in the glass mounting groove of the door / window sash 1, and the third sealing strip surrounds the glass mounting groove. The first sealing strip 11, the second sealing strip 12 and the third sealing strip are all made of EPDM material.

[0034] In this invention, a drainage component is located below the door / window frame 1. The drainage component includes a drainage channel 13 and drainage holes 14. The drainage channel 13 is located at the bottom of the outer frame 3 and extends along the length of the outer frame 3. Multiple drainage holes 14 are provided at the bottom of the drainage channel 13. One end of the drainage channel 13 is equipped with a sealing plate 15, and the other end is connected to the outside. This allows rainwater to drain smoothly. When rainwater enters the drainage channel, it is quickly discharged outdoors through the drainage holes, preventing rainwater from accumulating in the drainage channel and effectively preventing rainwater leakage.

[0035] Furthermore, in this invention, waterproof corner brackets 16 are provided at the corners of both the door / window frame 1 and the door / window sash 2. These waterproof corner brackets 16 are made of aluminum alloy and are fixed to the corners of the door / window frame and the door / window sash with screws. The waterproof corner brackets effectively prevent rainwater from leaking from the corners of the door / window frame and the door / window sash.

[0036] Installation Method: First, fabricate the door and window frames and sashes according to the dimensions of the door and window openings. When fabricating the door and window frames, ensure the mounting holes on the mounting flanges of the outer frame are accurately positioned, and that the first groove and first protrusion between the outer and inner frames fit tightly. Simultaneously, install the shock-absorbing pads. Secure the fabricated door and window frames to the wall using bolts through the mounting holes on the mounting flanges. During the fixing process, fill the space between the outer frame and the wall with waterproof sealant. Install the first sealing strip in the second groove of the door and window sash, install the second sealing strip on the inner wall of the inner frame, and install the third sealing strip in the glass mounting groove of the door and window sash. Connect the door and window sashes to the inner frame using hinges or latches. Adjust the position of the door and window sashes to ensure that when closed, the second protrusion accurately fits into the second groove, and the inner edge of the door and window sash is tightly fitted with the second sealing strip. Install waterproof corner brackets at the corners of the door and window frames and door and window sashes, and secure them firmly with screws.

[0037] In summary, this utility model has a novel structural design. By setting up multiple waterproof barriers, it can promptly drain rainwater that enters the door and window frames, preventing rainwater accumulation and further improving the waterproof performance of the doors and windows.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
