Description

Technical Field

[0001] This utility model relates to the field of windows, specifically to a waterproof structure for an inward-opening and tilt-and-turn window and a window having the same structure. Background Technology

[0002] Inward-opening and tilt-and-turn aluminum alloy windows, as a type of multifunctional window, have been widely used in modern buildings due to their unique opening mechanism and excellent ventilation performance.

[0003] However, in actual use, while traditional inward-opening and tilt-and-turn aluminum alloy windows perform well in terms of ventilation, safety, and dust prevention, their waterproofing performance is often unsatisfactory. This brings many inconveniences and potential safety hazards to users. In practical applications, users generally report that traditional inward-opening and tilt-and-turn aluminum alloy windows are prone to water seepage and leakage on rainy days, seriously affecting the dryness and comfort of the indoor environment.

[0004] Therefore, it is necessary to make further improvements to the existing technology. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a waterproof structure for an inward-opening, inward-tilting window.

[0006] Another objective of this invention is to propose an inward-opening and inward-tilting window.

[0007] To achieve the above objectives, on the one hand, an inward-opening and inward-tilting waterproof window structure according to an embodiment of the present utility model includes a first profile and a second profile.

[0008] The first profile has a first sealing strip at the front end of its side, a second sealing strip at the middle of its side, and a first sealing part at the rear end of its side.

[0009] The second profile is the side frame of an inward-opening and tilt-and-turn window sash. The second profile is positioned opposite to the first profile. The front end of the side of the second profile is provided with a second sealing part. The middle part of the side of the second profile is provided with a first thermal insulation strip. The rear end of the side of the second profile is provided with a third sealing strip.

[0010] When the inward-opening and tilt-and-turn window sash is in the closed state, the first sealing strip presses against the second sealing part, the first heat-insulating rubber strip presses against the second sealing strip, and the third sealing strip presses against the first sealing part, so as to form a first pressure equalization chamber and a second pressure equalization chamber that are adjacent to each other between the first profile and the second profile. Both the first pressure equalization chamber and the second pressure equalization chamber are connected to the outside.

[0011] According to an embodiment of this utility model, an inward-opening and tilt-and-turn waterproof window structure is provided. When the window sash is closed, the first sealing strip at the front end of the first profile side tightly presses against the second sealing part at the front end of the second profile side, forming a first sealing barrier to effectively prevent rainwater from seeping in from the front end. The second sealing strip in the middle of the first profile side and the first thermal insulation strip in the middle of the second profile side press against each other to form a second seal, further enhancing the waterproof effect. At the same time, the first thermal insulation strip also plays a role in heat insulation, optimizing the thermal performance of the window. The third sealing strip at the rear end of the second profile side presses against the first sealing part at the rear end of the first profile side, forming a third seal to ensure the waterproof performance of the rear end of the window. Through the synergistic effect of these three seals, this waterproof structure significantly improves the waterproof performance of the window, ensuring a dry and comfortable indoor environment. The first and second pressure equalization chambers formed between the first and second profiles are connected to the outside. This pressure equalization chamber design keeps the air pressure inside the chamber balanced with the outdoor air pressure, effectively preventing rainwater from seeping in due to pressure differences. In summary, this inward-opening and tilt-and-turn window waterproof structure, through the meticulous design of specific components and the formation of an isobaric cavity, significantly improves the window's waterproof performance, thermal performance, and the overall structural stability and durability, providing users with a more comfortable, safe, and energy-efficient living environment.

[0012] In addition, the waterproof structure for an inward-opening and inward-tilting window according to the above embodiments of this utility model may also have the following additional technical features:

[0013] According to one embodiment of the present invention, the first heat-insulating strip is T-shaped, both ends of the horizontal portion of the first heat-insulating strip are connected to the second profile, and the vertical portion of the first heat-insulating strip is sealed against the second sealing strip.

[0014] According to one embodiment of the present invention, the second sealing strip has a protrusion on the side facing the first heat-insulating adhesive strip, the rear end face of the protrusion is formed as a transverse plane, the vertical part of the first heat-insulating adhesive strip is sealed against the transverse plane, and the front surface of the protrusion is a gradually convex slope from front to back.

[0015] According to one embodiment of the present invention, the second sealing part and the first sealing strip are arranged opposite to each other, and one end of the first sealing strip extends toward the second profile and is inclined toward the second sealing part.

[0016] According to one embodiment of the present invention, the third sealing strip and the first sealing part are arranged opposite to each other.

[0017] According to one embodiment of the present invention, a buffer groove is formed on the side of the third sealing strip facing the second profile. The buffer groove is V-shaped and extends along the length direction of the third sealing strip.

[0018] According to one embodiment of the present invention, each of the first profile and the second profile has a mounting groove on the opposite side for mounting insulated glass, and each of the first profile and the second profile has a clamping member at its rear end, one end of the clamping member pressing against the insulated glass.

[0019] According to one embodiment of the present invention, a second heat-insulating strip is provided in the middle of the second profile, and the second heat-insulating strip extends along the length direction of the first profile.

[0020] According to one embodiment of the present invention, a mullion is provided on the front side of the first profile, and the mullion extends vertically.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a waterproof structure for an inward-opening and tilt-and-turn window, and an inward-opening and tilt-and-turn window having the same.

[0052] Reference Figures 1 to 4 As shown, an inward-opening and inward-tilting waterproof window structure according to an embodiment of the present utility model includes a first profile 10 and a second profile 20.

[0053] The first profile 10 is the frame of a window. The first profile 10 has a first sealing strip 11 at the front end of its side, a second sealing strip 12 at the middle of its side, and a first sealing part 13 at the rear end of its side.

[0054] The second profile 20 is the side frame of the inward-opening and tilt-and-turn window sash. The second profile 20 is arranged opposite to the first profile 10. The front end of the side of the second profile 20 is provided with a second sealing part 21. The middle part of the side of the second profile 20 is provided with a first heat-insulating strip 22. The rear end of the side of the second profile 20 is provided with a third sealing strip 23.

[0055] When the inward-opening and tilt-and-turn window sash is in the closed state, the first sealing strip 11 presses against the second sealing part 21, the first thermal insulation strip 22 presses against the second sealing strip 12, and the third sealing strip 23 presses against the first sealing part 13, forming a first pressure equalization chamber S1 and a second pressure equalization chamber S2 adjacent to each other between the first profile 10 and the second profile 20. Both the first pressure equalization chamber S1 and the second pressure equalization chamber S2 are connected to the outside. Advantageously, both the first pressure equalization chamber S1 and the second pressure equalization chamber S2 are connected to a drainage hole, which is also connected to the outside.

[0056] Based on the above, when the window sash is closed, the first sealing strip 11 at the front end of the side of the first profile 10 presses tightly against the second sealing part 21 at the front end of the side of the second profile 20, forming the first sealing barrier and effectively preventing rainwater from seeping in from the front end. The second sealing strip 12 in the middle of the side of the first profile 10 and the first thermal insulation strip 22 in the middle of the side of the second profile 20 press against each other to form a second seal, further enhancing the waterproof effect. At the same time, the first thermal insulation strip 22 also plays a role in heat insulation, optimizing the thermal performance of the window. The third sealing strip 23 at the rear end of the side of the second profile 20 presses against the first sealing part 13 at the rear end of the side of the first profile 10, forming a third seal, ensuring the waterproof performance of the rear end of the window. Through the synergistic effect of these three seals, this waterproof structure significantly improves the waterproof performance of the window, ensuring a dry and comfortable indoor environment.

[0057] Simultaneously, the first and second pressure-equalizing cavities S1 and S2, formed between the first profile 10 and the second profile 20, are connected to the outside. This pressure-equalizing cavity design ensures that the air pressure inside the cavity is balanced with the outdoor air pressure, effectively preventing rainwater infiltration due to pressure differences. For example, in the partially closed state, a small amount of water may enter the first cavity. Since the second pressure-equalizing cavity S2 is also pressure-equalizing, water cannot enter the second cavity, and the small amount of water entering the first cavity is discharged through the drainage hole of the openable fan frame.

[0058] It needs to be explained that the design of the first and second isobaric chambers S1 and S2 utilizes the rain curtain principle. The rain curtain principle is a design principle that refers to how rainwater penetration through a "curtain" is prevented. The main factor in applying this principle is the presence of a cavity inside the joint area. The pressure on the inner side of the outer surface must always be equal to the outdoor air pressure at all points, ensuring isobaric conditions on both sides of the outer surface, which is the "rain curtain." Pressure balance is achieved by intentionally keeping the opening open, allowing airflow between the cavity and the outside air. This effect is created by the cavities behind the outer wall (i.e., the first and second isobaric chambers S1 and S2 connected to the outside). These cavities must be connected to the outside to achieve the above purpose. Gust fluctuations caused by the randomness of wind also need to be balanced on both sides of the outer wall.

[0059] In summary, this inward-opening and tilt-and-turn window waterproof structure, through the meticulous design of specific components and the formation of an isobaric cavity, significantly improves the window's waterproof performance, thermal performance, and the overall structural stability and durability, providing users with a more comfortable, safe, and energy-efficient living environment.

[0060] It should be noted that the lengths of the second sealing part 21, the first heat-insulating strip 22, and the third sealing strip 23 protruding from the side of the second profile 20 gradually increase from front to back. At the same time, the lengths of the first sealing strip 11, the second sealing strip 12, and the first sealing part 13 protruding from the second profile 20 gradually decrease from front to back. In this way, interference between the various sealing structures can be effectively avoided when the inward-opening and inward-tilting window sash is opened and closed.

[0061] Preferably, in one embodiment of the present invention, the first heat-insulating strip 22 is T-shaped, both ends of the horizontal portion of the first heat-insulating strip 22 are connected to the second profile 20, and the vertical portion of the first heat-insulating strip 22 is sealed and abutted against the second sealing strip 12.

[0062] Understandably, traditional inward-opening and tilt-and-turn window sashes typically use an "I"-shaped thermal break strip, which lacks the function of forming a sealing barrier with the second window frame. Therefore, by setting the first thermal break strip 22 in a "T" shape, with its horizontal ends connected to the second profile 20 and its vertical ends sealing against the second sealing strip 12, not only is a stable connection between the first thermal break strip 22 and the second profile 20 and the second sealing strip 12 ensured, but it also provides enhanced thermal insulation.

[0063] Preferably, in one embodiment of the present invention, the second sealing strip 12 has a protrusion 121 formed on the side facing the first heat-insulating adhesive strip 22, the rear end face of the protrusion 121 is formed as a transverse plane, the vertical part of the first heat-insulating adhesive strip 22 is sealed against the transverse plane, and the front surface of the protrusion 121 is a gradually convex inclined surface from front to back.

[0064] Thus, because the rear end face of the protrusion 121 is designed as a horizontal plane, it provides a stable supporting surface for the vertical portion of the first thermal insulation strip 22. This design not only ensures a tight contact between the first thermal insulation strip 22 and the second sealing strip 12, but also significantly enhances the window's sealing performance by increasing the contact area. This helps prevent rainwater, dust, and other pollutants from seeping into the room through gaps, keeping the indoor environment clean and dry.

[0065] Meanwhile, the front surface of the protrusion 121 features a gradually convex bevel design from front to back. This design guides rainwater to the outside when the window is closed, reducing water accumulation at the sealing strip. The bevel design also disperses the impact force generated when the window is closed to some extent, protecting the sealing strip from damage and extending its service life.

[0066] Preferably, in one embodiment of the present invention, the second sealing part 21 and the first sealing strip 11 are arranged opposite to each other, one end of the first sealing strip 11 extends toward the second profile 20 and is inclined toward the second sealing part 21.

[0067] Thus, by tilting the first sealing strip 11 towards the second sealing part 21, the two can form a tighter fit when in contact, effectively reducing the presence of gaps. This tight fit not only enhances the sealing performance of the window, but also effectively prevents rainwater, dust, and other external pollutants from seeping into the room through the gaps, thereby maintaining a clean and dry indoor environment.

[0068] Preferably, in one embodiment of the present invention, the third sealing strip 23 and the first sealing part 13 are arranged opposite to each other.

[0069] Thus, because the third sealing strip 23 and the first sealing part 13 are arranged opposite each other, they can fit tightly together when the window is closed, effectively reducing the existence of gaps. This design significantly enhances the sealing performance of the window, preventing rainwater, dust and other external pollutants from seeping into the room through gaps, thereby maintaining a clean and dry indoor environment.

[0070] Preferably, in one embodiment of the present invention, a buffer groove 231 is formed on the side of the third sealing strip 23 facing the second profile 20. The buffer groove 231 is V-shaped and extends along the length direction of the third sealing strip 23.

[0071] Thus, the design of the "V"-shaped buffer groove 231 allows the third sealing strip 23 to form a tighter seal when it is attached to the second profile 20. The presence of the buffer groove 231 provides the sealing strip with a certain amount of elastic space, allowing it to better adapt to changes in the shape and size of the second profile 20, thereby reducing gaps and enhancing the sealing effect.

[0072] Meanwhile, the presence of the buffer groove 231 also enhances the overall structural stability of the window. During the opening and closing of the window, the buffer groove 231 can absorb and disperse stress, reducing wear and deformation between components. This not only extends the service life of the window but also improves its safety and reliability.

[0073] Preferably, in one embodiment of the present invention, a mounting groove 14 is provided on the opposite side of the first profile 10 and the second profile 20 for installing insulated glass, and a clamping member 15 is provided at the rear end of the first profile 10 and the second profile 20, one end of the clamping member 15 pressing against the insulated glass.

[0074] Thus, the mounting groove 14 provides a stable support structure for the insulated glass, ensuring the stability and safety of the glass during installation. Meanwhile, the design of the clamping element 15 further enhances the connection strength between the insulated glass and the frame, preventing the glass from loosening or falling off due to external forces during use, thereby improving the overall stability of the window.

[0075] Preferably, in one embodiment of the present invention, a second heat-insulating strip 16 is provided in the middle of the second profile 20, and the second heat-insulating strip 16 extends along the length direction of the first profile 10.

[0076] Thus, the second thermal break strip 16 extends along the length of the first profile 10, forming an effective thermal insulation barrier that significantly blocks the transfer of heat between the inside and outside, helping to improve the overall thermal insulation performance of the window, making the indoor temperature more stable, reducing energy consumption, and improving living comfort. The presence of the second thermal break strip 16 enhances the stability of the overall window structure. It helps to distribute the stress during the opening and closing of the window, reducing wear and deformation between components, thereby extending the service life of the window.

[0077] Preferably, in one embodiment of the present invention, the front side of the first profile 10 is provided with a mullion 17, and the mullion 17 extends vertically.

[0078] Thus, the mullion 17, as the middle connecting part of the door and window besides the frame, can provide additional support for the door and window. Especially in large-sized doors and windows, the presence of the mullion 17 can effectively prevent problems such as deformation and twisting due to the large area of ​​the door and window, making the overall structure of the door and window more stable.

[0079] On the other hand, an inward-opening and inward-tilting window according to an embodiment of the present invention has the waterproof structure of an inward-opening and inward-tilting window as described above.

[0080] Thus, when the window sash is closed, the first sealing strip 11 at the front end of the first profile 10 presses tightly against the second sealing part 21 at the front end of the second profile 20, forming the first sealing barrier and effectively preventing rainwater from seeping in from the front. The second sealing strip 12 in the middle of the side of the first profile 10 and the first thermal insulation strip 22 in the middle of the side of the second profile 20 press against each other to form a second seal, further enhancing the waterproof effect. At the same time, the first thermal insulation strip 22 also plays a role in heat insulation, optimizing the thermal performance of the window. The third sealing strip 23 at the rear end of the side of the second profile 20 presses against the first sealing part 13 at the rear end of the side of the first profile 10, forming a third seal and ensuring the waterproof performance of the rear end of the window. Through the synergistic effect of these three seals, this waterproof structure significantly improves the waterproof performance of the window, ensuring a dry and comfortable indoor environment.

[0081] Simultaneously, the first and second pressure-equalizing cavities S1 and S2, formed between the first profile 10 and the second profile 20, are connected to the outside. This pressure-equalizing cavity design ensures that the air pressure inside the cavity is balanced with the outdoor air pressure, effectively preventing rainwater infiltration due to pressure differences. For example, in the partially closed state, a small amount of water may enter the first cavity. Since the second pressure-equalizing cavity S2 is also pressure-equalizing, water cannot enter the second cavity, and the small amount of water entering the first cavity is discharged through the drainage hole of the openable fan frame.

[0082] In summary, this inward-opening and tilt-and-turn window, through the meticulous design of specific components and the formation of an isobaric cavity, significantly improves the window's waterproof performance, thermal performance, and the overall structural stability and durability, providing users with a more comfortable, safe, and energy-efficient living environment.
