[0028] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0029] like Figure 1 As shown, an energy-saving window of this application includes a window frame 1, double-glazed glass 2, thermal insulation strip 3, sealing strip 4, and hinges 5, among other key components.

[0030] As the core supporting structure of the entire window, the window frame 1 is installed in the reserved opening in the wall and is responsible for fixing and supporting the various components of the window. To ensure its strength and durability, the window frame 1 can be made of high-strength alloy material with good corrosion resistance, and is precisely aligned during installation to ensure the consistency and stability of the entire window.

[0031] Double-glazed windows (2) are a key component in achieving window insulation performance. A layer between the two panes of transparent glass creates a vacuum cavity, effectively isolating the transfer of external hot and cold air currents and reducing heat conduction. This layer is typically filled with an inert gas (such as argon or krypton), whose extremely low thermal conductivity allows it to more efficiently block energy transfer caused by temperature differences. Furthermore, the double-glazed windows are directly fitted inside the window frame (1) and tightly secured around the perimeter using specialized equipment, ensuring no gaps between the glass and the frame and preventing air or moisture intrusion that could damage its insulation properties.

[0032] To further improve thermal insulation performance, a thermal insulation strip 3 is installed at the junction of the window frame 1 and the double-glazed windows 2. The thermal insulation strip 3 is made of a low thermal conductivity composite material with a high thermal resistance value, forming an effective barrier between the metal window frame 1 and environments with large temperature variations. It is tightly attached to the junction of the two through precise inlay or bonding processes, preventing heat from being transferred through the highly conductive metal parts, reducing energy loss due to conduction, and improving the thermal comfort of the room. The proper layout of the thermal insulation strip 3 is crucial for effectively isolating indoor and outdoor heat.

[0033] The sealing strip 4 is arranged around the entire double-glazed unit 2 to enhance the airtightness and waterproof performance of the window system, preventing cold outside air from entering the room through gaps. The sealing strip 4 is typically made of highly elastic and aging-resistant rubber, exhibiting excellent deformation recovery and resistance to deformation and cracking over long-term use. Its installation position is located at the edge of the double-glazed unit and close to the frame surface. When closed, it relies on the friction generated by natural compression to tightly seal all joints, achieving a good sealing effect. When opened and then reset, it ensures accurate adhesion and maintains its functional characteristics each time, thus preventing slow indoor temperature rise caused by ventilation gaps during cold winters.

[0034] Finally, the component used to connect the movable parts of the window, such as the sash, to the fixed window frame 1 is the hinge 5. The hinge 5 is precision-cast and has an anti-corrosion coating to withstand various complex climatic environments. It is firmly embedded in one side of the window frame 1 and secured in place by a pin passing through the rotation axis, making the opening and closing operation both flexible and stable. At the same time, to enhance the sealing effect at the location of the hinge 5, an additional small-area sealing measure is specially designed to ensure that cold air will not flow back even after repeated opening and closing. The position of the hinge 5 not only affects the safety and smoothness of daily window use but also, from another perspective, ensures the overall airtightness of the window frame.

[0035] Overall, this energy-efficient window design, through the design and treatment of the window frame 1, double-glazed windows 2 and the vacuum plus inert gas within them, coupled with the auxiliary barrier of the thermal insulation strip 3 and the physical isolation barrier provided by the sealing strip 4, and the use of suitable hinges 5 to ensure a tight connection during every opening and closing action, significantly improves the building envelope's ability to self-regulate and maintain a suitable living environment under adverse external conditions. This reflects the concrete response of the modern building sector to energy conservation and emission reduction goals.

[0036] Continue to refer to Figure 1In one embodiment, the outer surface of the double-glazed insulated glass 2 of an energy-saving window according to this application is covered with a transparent heat-insulating film 7. This heat-insulating film has the function of reflecting sunlight and blocking ultraviolet rays. This design not only enhances the overall heat insulation performance of the window but also effectively reduces indoor energy loss. As an important component of the window, the double-glazed insulated glass 2 can significantly improve the thermal insulation effect of the building and further reduce energy consumption.

[0037] The double-glazed insulated glass 2 consists of two flat panes of glass filled with a low-thermal-conductivity inert gas, such as argon or krypton. When there are significant temperature differences in the external environment, the insulated layer effectively prevents heat conduction, maintaining a stable indoor temperature. A transparent heat-insulating film 7 is installed on the outer glass surface of the double-glazed insulated glass 2, ensuring that most of the heat radiation from direct sunlight is reflected back outdoors while allowing visible light to pass through. The transparent heat-insulating film 7 is achieved through special coating materials that highly reflect infrared and ultraviolet rays. Since long-term exposure to ultraviolet rays can cause furniture and decorations to fade, this structure also plays an important role in extending the lifespan of indoor furnishings.

[0038] Specifically, this transparent heat-insulating film 7 can be applied to the outer glass surface using vacuum coating technology or a spraying process. Vacuum coating involves depositing metal oxides or other composite materials onto the glass surface to form a nanoscale thin layer; while the spraying process involves spraying a material of specific components in liquid form and then curing it. Both methods can effectively achieve the desired heat insulation and UV protection functions while maintaining the high transparency of the glass.

[0039] In one embodiment, first refer to Figure 4 The thermal insulation strip 3 of an energy-saving window according to this application has a multi-layer composite structure. This composite structure consists of an outer low thermal conductivity rubber layer 8, a middle high-density foam plastic layer 9, and an inner aluminum alloy layer 10. The low thermal conductivity rubber layer 8 is in direct contact with the outer surface of the window frame and has extremely low thermal conductivity, effectively reducing heat transfer. The high-density foam plastic layer 9 is located between the rubber layer and the aluminum alloy layer 10, providing further thermal insulation and increasing the overall structural strength of the thermal insulation strip 3. The aluminum alloy layer 10, as the innermost material, is installed on the side closest to the interior, and its excellent mechanical properties ensure the durability of the entire thermal insulation strip 3.

[0040] This multi-layered composite thermal insulation strip 3 design fully considers the advantages of different materials in terms of heat transfer and durability. The rubber layer not only insulates against external temperatures but also provides a sealing function; high-density foam plastic provides efficient thermal insulation while reducing structural weight; and the aluminum alloy possesses high mechanical strength, effectively supporting and fixing the other two layers, making the entire thermal insulation strip 3 more stable and reliable. The close cooperation of each layer of materials forms a highly efficient thermal insulation barrier, greatly improving the overall energy efficiency and service life of the window.

[0041] For example, a low thermal conductivity rubber sheet of predetermined thickness and width can be prepared first, and then a pre-formed high-density foam plastic sheet can be coated or bonded onto it. Next, an aluminum alloy sheet is placed on top of the foam plastic sheet and fixed using mechanical means or adhesives. Throughout the assembly process, strict control of the interlayer adhesion strength and flatness is required to ensure the final formation of a thermal insulation strip 3 with good sealing and thermal insulation properties.

[0042] In one embodiment, the sealing strip 4 of an energy-saving window of this application consists of two parts. The first part is tightly fitted to the edge of the double-glazed insulated glass 2, preventing direct contact between the external and internal environments; the second part is tightly fitted to the inner wall of the window frame 1, ensuring that the entire window forms a sealed space, reducing heat loss and the intrusion of external moisture. This structural design enhances the airtightness and waterproof performance of the window, ensuring good performance under any weather conditions.

[0043] Specifically, the design of the sealing strip 4 fully utilizes the advantages of double sealing. By installing the first part of the sealing strip 4 at the edge of the double-glazed glass 2 and ensuring it adheres tightly to the glass surface, it effectively prevents external gases from entering the indoor space. Simultaneously, the second part of the sealing strip 4 is placed on the inner wall of the window frame 1 and tightly bonded thereto, creating a double sealing barrier between the entire window frame 1 and the double-glazed glass. This sealing strip 4 has good elasticity and compressibility, allowing the sealing effect to be adjusted according to different assembly requirements, ensuring no noticeable gaps after installation.

[0044] In one embodiment, during the manufacturing process, appropriate materials, such as silicone rubber and other sealing materials with good elasticity, wear resistance, and aging resistance, are first selected to manufacture the sealing strip 4. Subsequently, during installation, the first part of the sealing strip 4 is laid along the edge of the double-glazed insulated glass 2 and ensured to be tightly bonded with appropriate pressure; then, the second part is placed in the groove or surface inside the window frame 1 and fixed. Usually, a certain pre-tightening force is applied to the sealing strip 4 using specific tools to enhance its sealing effect, thereby ensuring the effective realization of the double sealing structure.

[0045] In one embodiment, the hinge 5 of an energy-saving window of this application is equipped with a self-lubricating bearing 11 at its connection point, thereby significantly reducing the friction generated during the opening and closing of the window. This design ensures that users can experience smooth and quiet operation during long-term use. Specifically, the self-lubricating bearing 11 is located at the connection point of the hinge 5, effectively replacing the direct friction between traditional metal contact surfaces, thus providing a smoother operating experience.

[0046] To further enhance the durability and stability of the window assembly, the bearing material is specially processed to possess excellent wear resistance and corrosion resistance, ensuring smooth operation under various environmental conditions. The bearing is internally filled with a highly efficient lubricating material, automatically providing adequate lubrication during prolonged operation without frequent external maintenance. Furthermore, through a scientifically designed structure, the bearing is tightly integrated with the hinge components, increasing the overall reliability of the mechanical system and enhancing its sealing performance, preventing dust and other impurities from entering and affecting its operation.

[0047] For example, the self-lubricating bearing 11 is embedded and securely fixed at the connection node of the hinge 5. The outer ring of the bearing fits tightly against the inner wall of the hinge 5 and is further secured by anti-loosening measures, while the inner ring forms a stable fit with the rotating shaft, enabling the entire device to maintain good motion accuracy and stability when subjected to external forces. With this design, the hinge 5 can more effectively support the daily opening and closing of the window.

[0048] In one embodiment, the window frame 1 of an energy-saving window of this application employs an embedded connection method at its four corners. Specifically, the embedded connection method uses specific connecting devices at the corners of the window frame 1 for fixation, ensuring that the window frame 1 has high rigidity and strength during assembly and long-term use. This connection design can effectively avoid energy loss caused by deformation of the window frame 1. Each corner is secured by a corner bracket 12 with a special shape (see...). Figure 1 The corner bracket 12 is not only used to connect the edges of adjacent window frames 1, but can also be engaged with connecting components through pre-drilled holes, ensuring a secure connection between the parts. In this way, the entire window frame 1 structure maintains good integrity and stability even under external forces. During actual installation, it is ensured that each component is precisely aligned and tightly fitted, improving sealing without compromising overall aesthetics.

[0049] For example, the corner bracket 12 can be made of metal, precision-machined to fit different window frame 1 size requirements, and has multiple threaded holes for direct fixing or use with other components. For instance, in a specific implementation, the ends of the four window frame 1 edge strips are first cut at a certain angle and then inserted into the positions where the corner bracket 12 has been installed. Fasteners such as screws are then passed through pre-drilled holes and screwed into the corresponding threaded holes, thus achieving a safe and stable connection at each corner. Furthermore, to enhance waterproofing, waterproof adhesive can be applied to the joints or waterproof gaskets can be installed to further prevent moisture intrusion and ensure the quality of the building's internal environment.

[0050] In one embodiment, such as Figure 2 As shown, the thickness of the double-glazed insulated glass 2 in this application's energy-saving window matches the depth of the window frame 1, thus ensuring installation stability and sealing. This design allows the double-glazed insulated glass to be seamlessly embedded in the window frame 1, ensuring a compact overall structure and avoiding the impact of external environmental factors on the energy-saving window's performance. Furthermore, a support pad 13 is provided along the lower edge of the glass. The support pad 13 is located at the bottom of the window frame 1 and is in close contact with the bottom edge of the double-glazed insulated glass 2, providing additional support, effectively buffering vibrations, and preventing structural loosening due to external impacts or long-term use, thereby ensuring that the sealing of the vacuum layer remains unaffected.

[0051] In one specific implementation, the depth of the window frame 1 is first measured and set, and then a suitable double-glazed pane is selected based on this dimension. During installation, the support pad 13 is placed at the corresponding position at the bottom of the window frame 1, and then the double-glazed pane 2 is placed smoothly on top of the support pad 13. In this way, not only is the glass fixed and stable, but the impact of external vibrations can also be reduced to a certain extent.

[0052] In one embodiment, such as Figure 3 As shown, the double-glazed insulated glass 2 of an energy-saving window according to this application consists of two parallel glass panels, forming a vacuum layer between them. Multiple tiny support columns 14 are uniformly arranged within this vacuum layer, distributed within the cavity between the glass panels. The function of the support columns is to maintain a constant spacing between the two glass panels, preventing deformation caused by thermal expansion and contraction of the glass due to changes in ambient temperature. These support columns exhibit high structural stability and do not significantly affect the vacuum insulation effect.

[0053] Specifically, the support columns are miniature columnar structures made of materials with good thermal conductivity, such as metal or ceramic. The height and diameter of each support column are carefully designed according to actual needs to ensure that it can maintain a stable structural state under certain mechanical pressure. In addition, the support columns are evenly distributed within the vacuum layer, which can distribute the force evenly and effectively avoid glass deformation caused by excessive pressure at a single point.

[0054] For example, during the molding of the two panes of glass, an adhesive layer needs to be sprayed onto the surface of one pane. Next, multiple support columns are bonded to the glass surface according to a pre-defined distribution. Then, the other pane of glass is precisely pressed onto the glass with the support columns using an automated process, ensuring a tight bond between the two and ultimately forming a sealed double-glazed structure. Throughout this process, strict control over processing precision and cleanliness is necessary to ensure the stable installation of the support columns within the vacuum layer.

[0055] In one embodiment, the surface of the thermal insulation strip 3 of the energy-saving window of this application that contacts the window frame 1 is provided with anti-slip grooves 15. This structure effectively enhances the friction between the thermal insulation strip 3 and the window frame 1. This design not only ensures that the thermal insulation strip 3 is not easily displaced during long-term use, but also maintains excellent thermal insulation performance. By adding anti-slip grooves 15 to the contact surface, the relative movement between the thermal insulation strip 3 and the window frame 1 is effectively suppressed, thereby improving the stability of the overall structure. This feature is particularly crucial for maintaining the long-term performance of the window.

[0056] Specifically, the anti-slip grooves 15 increase the actual contact area between the thermal break strip 3 and the window frame 1, and introduce more mechanical engagement points, which further enhances the friction between them. For example, several evenly distributed anti-slip grooves 15 can be manufactured on the contact surface of the thermal break strip 3 by machining or molding. These anti-slip grooves 15 can be linear, toothed, or serrated to adapt to different types of window frame 1 surfaces and installation requirements. This design significantly improves the physical fit and stability between components without affecting the appearance.

[0057] In one embodiment, the anti-slip groove 15 is provided on the side of the thermal insulation strip 3 that contacts the window frame 1. Through a reasonable layout and appropriate depth, it ensures that the anti-slip performance is maximized without affecting the thermal insulation performance. Furthermore, to ensure that the anti-slip groove 15 does not cause wear to the window frame 1, a flexible and durable material can be used as the main component of the thermal insulation strip 3. Specifically, during installation, the thermal insulation strip 3 is first tightly fitted to the corresponding position on the window frame 1, ensuring that it forms a firm and durable interface with the surface of the window frame 1. This structure enables the entire system to perform excellently in various environments, especially maintaining good thermal insulation and sealing performance even when exposed to prolonged wind pressure, temperature differences, and humidity variations.

[0058] In one embodiment, the inner surface of the window frame 1 of an energy-saving window of this application is coated with a waterproof coating 16 (see [link]). Figure 2This design effectively prevents moisture from entering the room through the window frame 1, thereby reducing heat loss due to moisture. By preventing moisture intrusion, energy-efficient windows also significantly extend the lifespan of the window frame 1. Specifically, the window frame 1 is one of the key components of an energy-efficient window, and moisture penetration often weakens its durability and increases maintenance costs. To avoid these problems, applying a suitable waterproof coating 16 to the inner surface of the window frame 1 is a necessary technical measure.

[0059] The compatibility and adhesion between the window frame material and the coating are crucial. Selecting coating materials with good adhesion and stability, and ensuring precise application techniques to guarantee the coating effect, are fundamental conditions for achieving effective waterproofing. Furthermore, considering the various environmental changes that may occur in real-world applications, the coating also needs sufficient flexibility and weather resistance. In addition, corresponding optimizations are made to the production process to ensure uniform coating and consistent thickness.

[0060] For example, waterproof coating can be applied to the inner surface of window frame 1 by spraying or brushing. Spraying is suitable for large-scale production lines, achieving a uniform coating thickness; brushing is more suitable for small-batch customized production, allowing for better control over local coating details. Both methods can meet the waterproof performance requirements of energy-efficient building windows in different application scenarios.

[0061] In one embodiment, return to reference Figure 1 The hinge 5 of an energy-saving window of this application is equipped with an anti-loosening bolt 17. The hinge 5 is installed at the connection between the window frame and the openable part. The purpose of this design is to ensure that the window can maintain stable connection performance during long-term frequent opening and closing, reduce gaps caused by loosening, and thus effectively prevent cold air from seeping into the room through the gaps.

[0062] To enhance the overall sealing and insulation of the window, the anti-loosening bolts 17 possess high locking force and durability, effectively preventing the hinge 5 components from naturally loosening due to prolonged use. This special fixing component provides necessary support and protection when the user repeatedly opens and closes the window. The hinge 5 itself may be made of metal materials, such as aluminum alloy or stainless steel, which have high mechanical strength and strong corrosion resistance, further improving the service life and quality of the device.

[0063] For example, in a practical application, technicians can precisely drill holes during the manufacturing process to secure the anti-loosening bolt 17 to its predetermined position. After installation, one end of the anti-loosening bolt 17 is fastened to the hinge 5, and the other end is firmly attached to the window frame or opening side. Specific installation procedures require ensuring sufficient preload and proper positioning adjustments to ensure that each connection is tight and evenly stressed.

[0064] In actual operation, when this device is used, an energy-saving window will effectively improve thermal insulation performance and optimize user experience through the close collaboration of its various components.

[0065] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
