Description

Technical Field

[0001] This utility model belongs to the field of window profile technology, and more specifically, it relates to a heat-insulating and energy-saving window with integrated window screen. Background Technology

[0002] Currently, most common insulated and energy-saving windows use single-cavity or multi-cavity window frames with thermal break strips to achieve a thermal break design, thereby reducing heat conduction through the metal profiles. However, the window frame and central column structures in existing technologies typically only meet basic partitioning and load-bearing functions, lacking optimized spatial layout design. It is difficult to efficiently integrate operable window sashes and multiple fixed glass units within the same window frame, especially when multiple functional areas need to be divided (such as ventilation, lighting, and shading), resulting in poor structural adaptability.

[0003] Existing window frame central pillars are mostly single-cavity or symmetrical thermal break structures, with simple connections to the window frame, uniform thermal break strip arrangements, and a lack of reinforcement designs for different stress areas. Furthermore, the ends of the central pillar profiles to the window frame lack effective protruding locking structures, resulting in loose fits with the pressure lines and seals, affecting assembly accuracy and sealing performance. In addition, traditional structures do not adequately consider the mechanical distribution within the cavity, lacking reinforcing structures such as T-shaped chambers to improve overall torsional strength and stability, making the window prone to deformation or sealing failure during long-term use.

[0004] For multi-zone window structures composed of window frames and central columns, achieving a reasonable integration layout between the upper left corner unit window sash and other fixed glass units (such as the first and second panes) while ensuring good thermal insulation performance remains a challenge in existing technologies. Current solutions often rely on additional connectors or complex splicing processes, which not only increase processing costs but also reduce the overall integration and structural reliability of the window.

Detailed Implementation

[0030] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0031] Example:

[0032] like Figures 1-11 As shown, a heat-insulating and energy-saving window with integrated window screen divides the entire window into three independent areas by setting a central column 5 inside the window frame 1. The upper left corner area is used to install an operable unit window sash, realizing the integration of ventilation, lighting, and shading functions. The other two areas are respectively fitted and fixed with the first glass 72 and the second glass 74. In this way, not only is the spatial layout optimized, but the convenience of use is also improved.

[0033] By installing a thermal break strip group 6 between the first chamber A51 and the first chamber B53 of the central column 5, a thermal break structure is constructed, effectively blocking the heat conduction path along the metal profile, thereby achieving the goal of significantly improving the overall window insulation performance. Furthermore, a first T-shaped chamber 52 is installed on the left side of the first chamber A51, enhancing the overall rigidity and bending / torsional strength of the central column, ensuring long-term stability and durability. By installing first protrusions A5101 at the upper and lower ends of the first chamber A51 near the thermal break strip group 6, and first protrusions B5301 and C5302 at the upper and lower ends of the first chamber B53 away from the thermal break strip group 6, a tight fit with the main pressure line 82 and other sealing components is achieved, improving overall sealing performance and preventing deformation and loosening.

[0034] Similarly, a thermal insulation strip group 6 is installed between the fourth chamber A11 and the fourth chamber B13 of the window frame 1, further enhancing the overall thermal insulation effect of the window. By setting a fourth T-shaped chamber 12 on the left side of the fourth chamber A11, the overall rigidity of the window frame is improved; by setting a fourth protrusion A1301 at the upper and lower ends of the side of the fourth chamber B13 away from the thermal insulation strip group 6, the structural support and sealing mating surface required for connection with other window sashes or walls are provided, thereby achieving the purpose of enhancing the local connection strength.

[0035] Thermal bridging is reduced by installing a thermal insulation strip group 6 between the third chamber A21 and the third chamber B22 of the inner frame 2. A third T-shaped protrusion A2102 is installed on the left side of the third chamber A21, with a third groove 2101 formed at the upper left corner, and a third protrusion B2103 is installed at the upper end near the thermal insulation strip group 6, enhancing local structural strength and aiding sealing. A tapered protrusion 2201 is installed at the bottom right corner of the third chamber B22 to facilitate drainage and reduce stress concentration. A pad 100 is installed between the inner frame 2 and the central column 5 to adjust the assembly gap, buffer thermal expansion and contraction stress caused by temperature changes, and prevent direct friction or deformation of the profiles, thereby extending service life.

[0036] A fifth protrusion A42 and a fifth protrusion B43 are provided at the upper and lower ends of the fifth chamber A41 of the glass sash 4, and a fifth mounting protrusion 44 is provided at the corner, with a fifth sealing strip A91 fitted in between. A fifth pressure seat 90 is also provided between two adjacent fifth mounting protrusions, with a fifth pressure line 81 fitting on its outer side. A fifth secondary protrusion A8103 and a fifth secondary protrusion B8102 are respectively provided on the upper and lower parts of the right side of the fifth pressure line 81, which tightly abut against the fifth sealing strip A91, achieving the first layer of sealing. A fifth T-shaped protrusion 8104 is provided in the middle, forming a fifth secondary groove 8105 between it and the fifth main body. The fifth pressure seat 90 includes a fifth pressure seat main body 901 and a fifth pressure seat protrusion 902. The fifth sealing strip B92 is fitted between the fifth pressure seat protrusion 902 and the fifth secondary groove 8105, forming a double-layer sealing system, which greatly improves the airtightness and watertightness of the glass assembly, effectively preventing air leakage and rainwater intrusion.

[0037] By fitting a main pressure line 82 onto the window frame 1 and the central column 5, and by having a main inclined portion 8201 with a main body slot A8203 at the front end and a main body slot B8202 at the rear, the main body slot A8203 engages with the first protrusion A5101 on the central column, achieving quick and secure assembly and improving installation efficiency and structural reliability.

[0038] Specifically, in actual production, in order to achieve the sealing between the entire window frame profile, unit sealing strips 200 can be installed at the connection between window frame 1 and inner frame 2, the installation point of screen sash 3 and screen window 73, the installation point of glass sash 4 and third glass 71, the connection between screen sash 3 and inner frame 2, the connection between glass sash 4 and inner frame 2, and the connection point of central column 5 with screen sash 3 and glass sash 4.

[0039] The innovative aspects of this solution will be further explained below.

[0040] The technical principle of this invention is based on the comprehensive optimization of heat conduction, structural mechanics, sealing performance, and functional integration in window and door systems. Through multi-dimensional collaborative design, it achieves a systemic breakthrough in high-performance energy-saving windows. Its core lies in the adoption of a fully thermally broken structure. From the window frame and central column to the inner frame, a double-chamber structure separated by thermal insulation strips 6 is set. Specifically, the fourth chamber A11 and fourth chamber B13 of the window frame, the first chamber A51 and first chamber B53 of the central column, and the third chamber A21 and third chamber B22 of the inner frame form a complete heat-blocking path. Because the thermal insulation strips 6 are made of low thermal conductivity materials, their thermal conductivity is much lower than that of aluminum alloy profiles, effectively blocking the direct conduction of heat through the metal profiles, significantly reducing the overall heat transfer coefficient of the window, thereby achieving excellent thermal insulation performance and reducing building energy consumption.

[0041] In terms of structural mechanics, this solution enhances overall strength and stability through optimized design of the internal cavities of the profiles. The central column 5 and window frame 1 are respectively equipped with a first T-shaped cavity 52 and a fourth T-shaped cavity 12. The T-shaped cross-section has a high moment of inertia and bending modulus, effectively resisting bending and torsional deformation caused by wind pressure and self-weight, preventing warping or sealing failure of the window after long-term use. Simultaneously, multiple protruding structures are set at key connection points, such as the first protrusion A5101, the first protrusion B5301, the first protrusion C5302, and the fourth protrusion A1301. These structures mechanically engage with the grooves of the main pressure line 82 during assembly, enhancing the shear strength and displacement resistance of the connection points and ensuring the structural reliability of the entire window under dynamic loads.

[0042] A multi-layered, elastically compensated sealing system is constructed. The main pressure line 82 is interference-fitted with the first protrusion A5101 via the main body groove A8203, providing initial pre-tightening force to ensure a secure assembly. For the glass assembly, a dual-seal design is adopted: the fifth sealing strip A91 is embedded in the fifth mounting protrusion 44 and pressed by the secondary protrusion of the fifth pressure line 81, forming the first static seal; the fifth sealing strip B92 is fitted into the fifth secondary groove 8105 between the fifth pressure seat 90 and the fifth pressure line 81, forming the second dynamic seal, which has a certain displacement adaptability and can compensate for the expansion and contraction of the profile caused by temperature changes, preventing seal failure. This dual sealing mechanism significantly improves the overall air tightness, water tightness, and anti-condensation performance of the window.

[0043] In terms of functional integration and assembly optimization, the window frame 1 is divided into three areas by the central column 5. An operable unit window sash is set in the upper left corner, and the remaining areas are fitted and fixed with the first glass 72 and the second glass 74, realizing an integrated layout of ventilation, lighting, and shading functions, improving space utilization efficiency and ease of use. The screen assembly and glass assembly are placed together in the unit window sash, avoiding the dust accumulation and damage problems of externally mounted screens, resulting in a neat and beautiful appearance. During assembly, the fifth T-shaped protrusion 8104 of the fifth pressure line 81 and the protrusion of the fifth pressure seat 90 form a self-positioning structure, enabling fast and accurate installation and improving assembly efficiency. In addition, the pad 100 set between the inner frame 2 and the central column 5 acts as an elastic buffer element, which can absorb the stress generated by thermal expansion and contraction, avoiding profile cracking or seal damage caused by rigid connection, and extending the service life of the entire window.
