Abstract
Description
Technical Field
[0001] The present application relates to the field of thermal insulation aluminum alloy doors and windows, and in particular to an energy-saving and heat-insulating thermal insulation aluminum alloy door and window. Background Art
[0002] The thermal break aluminum alloy profile is an improved type launched on the basis of the old aluminum alloy profile in order to improve the thermal insulation performance of doors and windows. The principle of the thermal break aluminum alloy profile is to use P66 nylon to separate and tightly connect the indoor and outdoor layers of aluminum alloy into a whole, forming a new heat-insulating aluminum profile.
[0003] The thermally-insulated aluminum doors and windows include window frames and window sashes. The window frames are hinged to the window sashes. The window frames near the wall include an airtight cavity, an isobaric cavity, and a watertight cavity in the thickness direction from indoor to outdoor. The inner frame of the window sash is fixedly connected with a sealing strip, the outer frame of the window frame is fixedly connected with a water-blocking strip, and the window sash and the inside of the window frame are respectively fixedly connected with isobaric strips. When the window sash and the window frame are closed, the sealing strip of the window sash abuts against the outside of the watertight cavity, the water-blocking strip of the window frame abuts against the outside of the window sash, and the two isobaric strips abut against each other, realizing a three-line sealing structure and achieving the effect of thermal insulation.
[0004] Regarding the above-mentioned related technologies, although the traditional thermally insulated aluminum alloy doors and windows can achieve a certain degree of sealing when the window sash and the window frame are closed, the cavity in the horizontal thickness direction at the abutment position of the window sash and the window frame is less, which leads to certain limitations in the thermal insulation effect of the doors and windows. In the winter in the north, the poor thermal insulation effect of doors and windows will cause heat exchange between indoors and outdoors, thereby increasing the energy consumption of the heating system. Utility Model Content
[0005] In order to improve the thermal insulation effect of thermally-insulated aluminum alloy doors and windows and thereby achieve energy-saving effects, the present application provides an energy-saving and thermally-insulating thermally-insulated aluminum alloy door and window.
[0006] The energy-saving and heat-insulating thermal insulation aluminum alloy door and window provided in this application adopts the following technical solution:
[0007] An energy-saving and heat-insulating broken bridge aluminum alloy door and window, comprising a door and window body, the door and window body comprising a window frame and a window sash, the window frame being provided with a watertight cavity, a first isobaric cavity and a first airtight cavity in sequence along the thickness direction of the door and window body; the window sash being provided with a connecting cavity, a second isobaric cavity and a second airtight cavity in sequence along the thickness direction of the door and window body; a water-blocking rubber strip being provided on the outside of the watertight cavity, and an airtight rubber strip being provided on the outside of the second airtight cavity; a first isobaric rubber strip being provided on the outside of the first isobaric cavity, and a second isobaric rubber strip being provided on the outside of the second isobaric cavity;
[0008] The first isobaric rubber strip comprises a supporting portion and an abutting portion, wherein the abutting portion is located on a side of the supporting portion away from the first isobaric cavity, the abutting portion comprises a plurality of protrusions, and a cavity is provided inside each of the plurality of protrusions; the supporting portion is connected to an outer wall of the first isobaric cavity;
[0009] When the window sash and the window frame are closed, the water-blocking rubber strip abuts against the outside of the connecting cavity, the plurality of protrusions abut against the second isobaric rubber strip together, and the airtight rubber strip abuts against the outside of the first airtight cavity.
[0010] By adopting the above technical solution, when the window sash and the window frame are closed, the water-blocking rubber strip abuts against the outside of the connecting cavity to form a seal. Multiple protrusions abut against the second isobaric rubber strip together to form a multi-pass seal. At the same time, the airtight rubber strip abuts against the outside of the first airtight cavity to form the last seal. The sealing structure of multiple cavities formed by multiple seals jointly improves the thermal insulation performance of doors and windows. This structure not only blocks the direct transfer of heat, but also effectively reduces the thermal bridge effect and improves energy saving by creating multiple insulation layers between indoors and outdoors. In addition, the design of multiple cavities also helps to reduce the transmission of sound waves between indoors and outdoors, further improving the sound insulation performance of doors and windows, and creating a more comfortable and quiet indoor environment for users.
[0011] Optionally, a plurality of heat-insulating strips are provided on a side of the support portion close to the first airtight cavity, and the plurality of heat-insulating strips are arranged along the thickness direction of the door and window body; and the plurality of heat-insulating strips can abut against the outer side of the first airtight cavity.
[0012] By adopting the above technical solution, the heat insulation strips are evenly distributed in the thickness direction of the door and window body, and are closely abutted against the outer side of the first airtight cavity, forming an additional multi-cavity heat insulation barrier. This design not only effectively prevents the transfer of heat, but also enhances the structural stability of the first isobaric strip.
[0013] Optionally, the plurality of protrusions increase in size in sequence along the thickness direction of the door and window body, and the protrusions close to the water-blocking rubber strip are larger than the protrusions far from the water-blocking rubber strip.
[0014] By adopting the above technical solutions, this optimization not only makes the closing process of doors and windows more labor-saving, but also enhances the sealing. The larger protrusion near the water-blocking strip helps to form a closer contact when the window sash and window frame are closed, thereby improving the sealing effect and reducing the infiltration of air and moisture.
[0015] Optionally, the side wall of the protrusion close to the water-blocking rubber strip is bent toward the side away from the water-blocking rubber strip, and when the window sash and the window frame are closed, the side wall of the protrusion close to the water-blocking rubber strip away from the water-blocking rubber strip abuts against the side wall of the second isobaric rubber strip.
[0016] By adopting the above-mentioned technical solution, when the window sash and the window frame are closed, the side wall of the protrusion away from the water-blocking rubber strip abuts against the side wall of the second isobaric rubber strip. The bent side wall provides support force for the current protrusion toward the second isobaric rubber strip, thereby increasing the strength of the protrusion, achieving close abutment between the protrusion and the second isobaric rubber strip, and further enhancing the sealing effect.
[0017] Optionally, the abutting surface between the second isobaric rubber strip and the protrusion is an inclined surface, and the inclined surface is inclined from a side close to the airtight rubber strip to a side close to the water-blocking rubber strip to a side away from the protrusion.
[0018] By adopting the above technical solution, the design of the second isobaric rubber strip adopts a sloped structure with the raised abutment surface. This design provides a smooth pressing action when the window sash and the window frame are closed, which ensures the sealing effect while making the window closing action more labor-saving.
[0019] Optionally, the side wall of the second isobaric rubber strip close to the airtight rubber strip is bent toward a side away from the airtight rubber strip; the side wall of the second isobaric rubber strip close to the water-blocking rubber strip is bent toward a direction close to the water-blocking rubber strip.
[0020] By adopting the above technical solution, the side wall of the second isobaric rubber strip is designed to bend toward the side away from the airtight rubber strip and toward the water-blocking rubber strip. This bending design on both sides provides additional support for the rubber strip, enhances its structural stability, and ensures the sealing performance under long-term use.
[0021] Optionally, the interiors of the watertight cavity, the first isobaric cavity, the first airtight cavity, the connecting cavity, the second isobaric cavity and the second airtight cavity are all filled with polyurethane.
[0022] By adopting the above technical solution, polyurethane, as a highly efficient thermal insulation material, greatly improves the thermal insulation performance of doors and windows. The low thermal conductivity of polyurethane makes it an ideal thermal insulation material, which can effectively prevent the transfer of heat, reduce the heat exchange between indoor and outdoor, enhance the thermal insulation performance of aluminum alloy doors and windows, and improve the energy saving effect.
[0023] Optionally, reinforcing ribs are arranged on the outside of the connecting cavity, and the length direction of the reinforcing ribs is arranged along the length direction of the connecting cavity.
[0024] By adopting the above technical solution, the application of reinforcing ribs significantly enhances the structural strength of the connection cavity and improves the overall stability and durability of the doors and windows. The reinforcing ribs are arranged along the length direction of the connection cavity, providing additional support for the window sash and reducing the possibility of deformation of the window frame under wind pressure or other external forces.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. By setting up a sealing structure with multiple cavities and multiple seals, multiple sealing barriers are formed when the window sash and window frame are closed, which significantly improves the thermal insulation performance of doors and windows, reduces the exchange of indoor and outdoor heat, and thus reduces the energy consumption of the heating system.
[0027] 2. The present invention adopts a convex design of a cavity structure. Due to the existence of the cavity, the medium for heat conduction is reduced, further enhancing the heat insulation effect of doors and windows. At the same time, the design of the inclined surface and the bent side wall also makes the abutment between the isobaric rubber strips tighter, thereby improving the sealing performance.
[0028] 3. In the present invention, by adding heat insulation strips and filling multiple cavities with polyurethane, the transfer of heat is effectively prevented, thereby ensuring the thermal insulation effect of doors and windows under extreme climatic conditions.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0035] The present application embodiment discloses an energy-saving and heat-insulating thermal insulation aluminum alloy door and window. Figure 1 An energy-saving and heat-insulating aluminum alloy broken bridge door and window comprises a door and window body 1, the door and window body 1 comprises a window frame 2 and a window sash 3, the window frame 2 comprises a watertight cavity 21, a first isobaric cavity 22 and a first airtight cavity 23, the watertight cavity 21 and the first airtight cavity 23 are made of aluminum alloy profiles, a first sealing strip 24 and a second sealing strip 25 are arranged between the watertight cavity 21 and the first airtight cavity 23, and the first sealing strip 24, the second sealing strip 25, the watertight cavity 21 and the first airtight cavity 23 together enclose the first isobaric cavity 22. The watertight cavity 21, the first isobaric cavity 22 and the first airtight cavity 23 are arranged in sequence along the thickness direction of the door and window body 1 from outdoor to indoor. The window sash 3 includes a connecting cavity 31, a second isobaric cavity 32 and a second airtight cavity 33, the connecting cavity 31 and the second airtight cavity 33 are made of aluminum alloy profiles, a third sealing strip 34 and a fourth sealing strip 35 are arranged between the connecting cavity 31 and the second airtight cavity 33, and the third sealing strip 34, the fourth sealing strip 35, the connecting cavity 31 and the second airtight cavity 33 together enclose the second isobaric cavity 32. The connecting cavity 31, the second isobaric cavity 32 and the second airtight cavity 33 are sequentially arranged along the thickness direction of the door and window body 1 from the outdoors to the indoors.
[0036] Reference Figure 1 The outer side of the watertight cavity 21 is provided with a water-blocking rubber strip 4 to prevent external moisture from penetrating. The outer side of the second airtight cavity 33 is provided with an airtight rubber strip 5 to ensure the airtightness when the window sash 3 and the window frame 2 are closed. The first sealing strip 24 is provided with a first isobaric rubber strip 6 on the side away from the first isobaric cavity 22, and the third sealing strip 34 is fixed with a second isobaric rubber strip 7 on the side away from the second isobaric cavity 32.
[0037] Reference Figure 2The first isobaric rubber strip 6 includes a supporting portion 61 and an abutting portion 62. The abutting portion 62 is located on a side of the supporting portion 61 away from the first isobaric cavity 22. The abutting portion 62 includes a plurality of protrusions 621, each of which has a cavity therein. The design of the cavity can reduce the medium for heat conduction and improve the heat insulation effect.
[0038] When the window sash 3 and the window frame 2 are closed, the water-blocking rubber strip 4 abuts against the outside of the connection cavity 31 to form a seal. The multiple protrusions 621 abut against the second isobaric rubber strip 7 together to form a multi-pass seal. At the same time, the airtight rubber strip 5 abuts against the outside of the first airtight cavity 23 to form the last seal. The sealing structure of multiple cavities formed by the multi-pass seals jointly improves the thermal insulation performance of the doors and windows.
[0039] Further, see Figure 1 and Figure 2 The support portion 61 is connected to the first sealing strip 24 through two connection points near the first airtight cavity 23, providing stable support for the abutment portion 62 to ensure the stability of the structure. A plurality of heat insulation strips 611 are fixedly connected between the two connection points, and the plurality of heat insulation strips 611 are evenly arranged along the thickness direction of the door and window body 1. The plurality of heat insulation strips 611 can abut against the outer side of the first airtight cavity 23. The addition of the heat insulation strips 611 further prevents the transfer of heat and improves the thermal insulation effect of the door and window.
[0040] Reference Figure 1 and Figure 2 The plurality of protrusions 621 increase in size in the thickness direction of the door and window body 1, and the protrusions 621 close to the water-blocking rubber strip 4 are larger than the protrusions 621 away from the water-blocking rubber strip 4. This structural design ensures that the protrusions 621 are in close contact with the second isobaric rubber strip 7 to enhance the sealing performance, while making the door and window closing process more labor-saving.
[0041] Reference Figure 2 The side wall of the protrusion 621 close to the water-blocking rubber strip 4 is bent toward the side away from the water-blocking rubber strip 4. When the window sash 3 and the window frame 2 are closed, the side wall of the protrusion 621 away from the water-blocking rubber strip 4 abuts against the side wall of the second isobaric rubber strip 7, and the bent side wall provides support force for the current protrusion 621 toward the second isobaric rubber strip 7, thereby improving the strength of the protrusion 621, achieving close abutment between the protrusion 621 and the second isobaric rubber strip 7, and further enhancing the sealing effect.
[0042] Further, see Figure 1The contact surface between the second isobaric rubber strip 7 and the protrusion 621 is designed as an inclined surface. The inclined surface is inclined from the side close to the airtight rubber strip 5 to the side close to the water blocking rubber strip 4 to the side away from the protrusion 621. This inclined surface design allows the protrusion 621 to be pressed into the second isobaric rubber strip 7 more smoothly during the closing process of the window sash 3 and the window frame 2, which makes the window closing action more labor-saving while ensuring the sealing effect, and improves the user experience.
[0043] Reference Figure 1 In order to further enhance the structural strength of the second isobaric rubber strip 7, the side wall close to the airtight rubber strip 5 is also bent toward the side away from the airtight rubber strip 5. At the same time, the side wall of the second isobaric rubber strip 7 close to the water-blocking rubber strip 4 is bent toward the water-blocking rubber strip 4. During the window closing process, the protrusion 621 rubs and squeezes the second isobaric rubber strip 7, which will give the second isobaric rubber strip 7 a force in the direction of the airtight rubber strip 5. These bent side walls will provide a supporting force in the opposite direction to the second isobaric rubber strip 7, thereby improving the structural stability of the second isobaric rubber strip 7. The sealing performance for long-term use is ensured.
[0044] Reference Figure 1 In order to further improve the thermal insulation effect of the doors and windows, the watertight cavity 21, the first isobaric cavity 22, the first airtight cavity 23, the connecting cavity 31, the second isobaric cavity 32 and the second airtight cavity 33 are all filled with polyurethane. As an excellent thermal insulation material, polyurethane can effectively prevent the transfer of heat, thereby improving the thermal insulation performance of the doors and windows.
[0045] Further, see Figure 1 A reinforcing rib 8 is also fixedly connected to the outside of the connecting cavity 31. The length direction of the reinforcing rib 8 is arranged along the length direction of the connecting cavity 31, which is used to enhance the structural strength of the window sash 3 of the connecting cavity 31, reduce the possibility of deformation of the window frame 2 under wind pressure, and improve the stability and safety of the door and window during use.
[0046] The implementation principle of the energy-saving and heat-insulating aluminum alloy door and window of the embodiment of the present application is as follows: by setting a sealing structure with multiple cavities and multiple seals, a multiple sealing barrier is formed when the window sash 3 and the window frame 2 are closed, which significantly improves the heat insulation performance of the door and window. At the same time, by preferably adopting the design of the protrusion 621 of the cavity structure, adding the heat insulation strip 611, filling polyurethane in multiple cavities, and adding the reinforcing rib 8, the heat insulation effect and structural stability of the door and window are further enhanced, thereby reducing the exchange of indoor and outdoor heat and the energy consumption of the heating system.
[0047] The embodiments of the present application have the effect of improving the thermal insulation effect of the thermally-insulated aluminum alloy doors and windows, thereby achieving energy-saving effects.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
