Abstract
Description
Technical Field
[0001] This utility model relates to an insulated window, and more particularly to a flat-mounted, concealed-sash, slim heat-insulating window, belonging to the technical field of insulated window equipment. Background Technology
[0002] Concealed window sashes allow the entire window or door sash to be hidden behind the door frame, creating a seamless, integrated look similar to a glass curtain wall when viewed from the outside, resulting in an aesthetically pleasing facade. Furthermore, concealed window sashes offer advantages such as saving materials and increasing natural light, making them increasingly popular.
[0003] Currently, the market offers a wide variety of windows, but they still have some shortcomings in terms of thermal insulation performance, aesthetics, and structural rationality. Common window opening sash designs result in differences between the opening and fixed sashes on the same vertical plane. This not only affects the overall visual appeal but also exacerbates issues with material usage and splicing when windows are tall or designed as large-format windows or vertical strip windows. This leads to increased material consumption, poor appearance, and potential safety hazards. Furthermore, some windows with thermal insulation features have inadequate insulation structures, failing to effectively meet the energy-saving and comfort requirements of modern buildings.
[0004] Therefore, this utility model proposes a new solution. Utility Model Content

[0006] The objective of this utility model can be achieved by adopting the following technical solution:
[0007] A flat-mounted, concealed-sash, slim, thermally insulated window includes a window frame and a window sash. The window frame includes an outer frame and an inner frame, which are connected to each other by two parallel first thermal insulation strips. The window sash includes an outer sash and an inner sash, which are connected to each other by a multi-cavity thermal insulation strip. A double-glazed pane is provided between the outer sash and the inner sash. A first sealant is installed between the outer sash and the double-glazed pane. An extended sealant located on the back of the outer sash is attached to the first sealant. The outer frame includes an extended edge plate extending towards one side of the window sash, which is flush with the extended sealant. The inner sash includes an extended edge plate extending towards one side of the window frame, which is flush with the inner frame.
[0008] Preferably, an equal pressure strip is provided between the window frame and the window sash, and the equal pressure strip abuts against the multi-cavity thermal insulation strip when the window is closed.
[0009] Preferably, thermal insulation cotton is installed between the two first thermal insulation strips and inside the cavities of the multi-cavity thermal insulation strip.
[0010] Preferably, a second sealing strip is connected between the inner edge plate and the inner frame.

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0022] like Figures 1-2 As shown, the flat-loaded, concealed-sash, slim thermal insulation window provided in this embodiment includes a window frame 1 and a window sash 2. The window frame 1 includes an outer frame 3 and an inner frame 4, which are connected to each other by two parallel first thermal insulation strips 5. The window sash 2 includes an outer sash 6 and an inner sash 7, which are connected to each other by a multi-cavity thermal insulation strip 8. A double-glazed glass 9 is provided between the outer sash 6 and the inner sash 7. A first sealant 10 is installed between the outer sash 6 and the double-glazed glass 9. An extended sealant 11 located on the back of the outer sash 6 is connected to the first sealant 10. The outer frame 3 includes an extended edge plate 12 extending to one side of the window sash 2, which is flush with the extended sealant 11. The inner sash 7 includes an extended edge plate 13 extending to one side of the window frame 1, which is flush with the inner frame 4. With the window frame 1 and window sash 2 both made of thermally broken aluminum, the window frame 1 and window sash 2 achieve an extremely slim and stable structure, with the visible surfaces presented flush. The vertical and horizontal mullions of the profile have the same width, strong versatility, and are conducive to mass production, reducing costs. The flat-load type and concealed sash design not only make the window look simple and elegant, but also reduce safety hazards. The perfect thermal break strip design greatly improves the thermal insulation performance, meeting the energy-saving requirements of modern buildings. In addition, the window is easy to install and disassemble, has a stable structure, strong adjustability, and effectively saves consumables. With the setting of the first sealant 10 and the extended sealant 11, when the outer sash 6 is extremely slim, the first sealant 10 ensures the sealing and fixing of the insulated glass 9, and the extended sealant 11 works with the outer edge plate 12 to seal, and together with the equal pressure strip 14 and the third sealant strip 17, it can still achieve a triple seal, thereby ensuring the sealing effect.
[0023] like Figures 1-2 As shown, an equal-pressure sealing strip 14 is provided between the window frame 1 and the window sash 2. The equal-pressure sealing strip 14 abuts against the multi-cavity thermal insulation strip 8 when the window is closed. Thermal insulation cotton 15 is installed between the two first thermal insulation strips 5 and inside the cavities of the multi-cavity thermal insulation strip 8. A second sealing strip 16 connects the inner edge panel 13 and the inner frame 4. A third sealing strip 17 connects the inner sash 7 and the insulated glass 9. A support strip is provided on the inner side of the insulated glass 9, and a molecular sieve 18 is installed on the inner side of the support strip. The thermal insulation cotton 15 improves the thermal insulation effect, and the molecular sieve 18 can absorb moisture and dry the air.
[0024] In this embodiment, as Figures 1-2 As shown in the figure, the working principle of a flat-mounted, concealed-sash, slim thermal insulation window provided in this embodiment is as follows:
[0025] Both the window frame 1 and the window sash 2 are made of thermally broken aluminum. The window frame 1 and window sash 2 are extremely thin and stable, with the visible surfaces presented in a flush state. The vertical and horizontal mullions of the profile are of the same width, which is highly versatile, conducive to mass production, and reduces costs. The flat-load type and concealed sash design not only make the window look simple and elegant, but also reduce safety hazards. The perfect thermal insulation strip design greatly improves the thermal insulation performance, which meets the energy-saving requirements of modern buildings. In addition, the window is easy to install and disassemble, has a stable structure, and is highly adjustable, effectively saving consumables. With the setting of the first sealant 10 and the extended sealant 11, when the outer sash 6 is extremely thin, the first sealant 10 ensures the sealing and fixing of the insulated glass 9, and the extended sealant 11 works with the outer edge plate 12 to seal, and together with the pressure equalization strip 14 and the third sealant strip 17, it can still achieve a triple seal, thereby ensuring the sealing effect.
[0026] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
