Description

Technical Field

[0001] This application relates to the technical field of doors and windows, and more specifically, to an ultra-low energy consumption integrated double-inside-opening passive window. Background Art

[0002] With the intensification of the global energy crisis and the improvement of environmental protection awareness, energy-saving buildings have gradually become the development trend of the construction industry. Among building energy consumption, the energy dissipated through windows accounts for a quite large proportion. Therefore, developing highly energy-efficient windows is of great significance for reducing the energy consumption of buildings. As a new type of energy-saving window, the design concept of passive windows is to reduce the transmission and loss of energy between the indoor and outdoor of buildings through the material and structure design of the windows themselves, so as to achieve the effect of energy conservation.

[0003] Although traditional passive windows have achieved certain results in energy-saving performance, there are still some deficiencies in practical applications. First, there are many attached frame profiles in traditional passive windows, resulting in a complex structure, which not only increases the development cost but also makes the assembly process more complex. Second, due to the bulky thermal insulation structure, most passive windows on the market are single passive windows, which limits their adaptability to different building environments. Under the structure of traditional passive windows, the screen window solution usually requires additional external hanging screen windows or retractable screen windows. Both of these screen windows are attached outside the product structure, which destroys the integrity of the original doors and windows and is inconvenient for users to operate, affecting the user experience.

[0004] Therefore, there is a lack of a passive window on the market that can not only provide high-efficiency thermal insulation, but also has a simple thermal insulation structure and does not affect the installation of other structures of the doors and windows. In view of the above problems, the existing technology urgently needs to be improved. Summary of the Utility Model

[0005] The purpose of this application is to provide a low-energy consumption integrated double-opening passive window. By adopting a double-layer heat insulation structure in both the window frame and the window sash, that is, two spaced heat insulation strips are arranged between the outer profile and the inner profile to form a heat preservation cavity, the heat preservation performance of the window is increased and heat transfer is reduced.

[0006] In a first aspect, an ultra-low energy consumption integrated double-inside-opening passive window includes a window frame and a window sash hinged in the window frame.

Detailed Embodiments

[0030] Next, in combination with the accompanying drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Components of the embodiments of the present application described and marked in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0031] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] Currently, additional screen fans are provided in the screen structures on the market. The additional screen fans will cause the gap between the screen structure and the outdoor profile of the window frame to decrease. When the rainwater cannot be drained in time, it will enter the room along the gaps of the doors and windows, and its waterproof effect is poor. To solve this problem, the present application provides a low-energy consumption integrated double-opening passive window.

[0033] Please refer to Figures 1 to 3 , in a first aspect, an ultra-low energy consumption integrated double-inside-opening passive window includes a window frame and a window sash hinged in the window frame.

[0034] The window frame at least includes an outer frame outer profile 11 and an outer frame inner profile 12 that are spaced apart in the horizontal direction. A window frame heat insulation strip 13 is provided between the outer frame outer profile 11 and the outer frame inner profile 12. The window frame heat insulation strip 13 is at least spaced apart in the vertical direction by two. Two window frame heat insulation strips 13 are spaced to form a first heat preservation cavity 32.

[0035] The window sash at least includes a window sash outer profile 14 and a window sash inner profile 15 that are spaced apart in the horizontal direction. A window sash heat insulation strip 16 is provided between the window sash outer profile 14 and the window sash inner profile 15. The window sash heat insulation strip 16 is at least spaced apart in the vertical direction by two. Two window sash heat insulation strips 16 are spaced to form a second heat preservation cavity 34.

[0036] The first heat preservation cavity 32 and the second heat preservation cavity 34 are filled with heat insulation materials.

[0037] Among them, the ultra-low energy consumption integrated double-inward-opening passive window of the present application mainly includes a window frame and a window sash hinged in the window frame, and the window sash opens inwardly. The window frame at least includes an outer frame outer profile 11 and an outer frame inner profile 12 that are spaced apart in the horizontal direction, and a window frame heat insulation strip 13 is provided between these two profiles. Among them, at least two window frame heat insulation strips 13 are spaced apart in the vertical direction, and a first heat preservation cavity 32 is formed between the two window frame heat insulation strips 13, and the first heat preservation cavity 32 improves the heat preservation performance of the window frame. The window frame can adopt a window frame with a total width of 125 mm.

[0038] Similarly, the window sash also adopts a similar structural design. The window sash at least includes a window sash outer profile 14 and a window sash inner profile 15 that are spaced apart in the horizontal direction, and a window sash heat insulation strip 16 is provided between these two profiles. The window sash heat insulation strip 16 is at least spaced apart in the vertical direction by two, and a second heat preservation cavity 34 is formed between the two window sash heat insulation strips 16, and the second heat preservation cavity 34 improves the heat preservation and heat insulation performance of the window sash. The window sash can adopt a window sash with a total width of 105 mm, and the window sash can be installed inside the window frame, and a width of 20 mm is reserved in the horizontal direction to facilitate the subsequent installation of the screen window structure.

[0039] In order to further improve the overall heat preservation effect, the present application fills the first heat preservation cavity 32 and the second heat preservation cavity 34 with a heat insulation material, and the heat insulation material can be polyurethane foam. Among them, since both the first heat preservation cavity 32 and the second heat preservation cavity 34 are arranged in the vertical direction, therefore, the first heat preservation cavity 32 and the second heat preservation cavity 34 can form a larger vertical heat preservation cavity, and the structure of the vertical heat preservation cavity is simple and the heat preservation cost is low, without the need for an additional frame design outward. It not only realizes efficient heat preservation, but also simplifies the overall structure by reducing the use of complex components, thereby reducing the production cost.

[0040] Therefore, compared with traditional passive windows, the design of the present application has significant advantages. First, the design of the double-layer heat insulation structure and the heat preservation cavity greatly improves the heat preservation and heat insulation performance of the window. Secondly, the simplified structural design reduces the production cost, making the high-performance passive window more affordable. Moreover, the inward-opening window sash increases the adaptability of the window and can meet different building environments and user needs. Finally, the simplification of the heat preservation structure enables the passive window to have enough space to install a screen window, solving the problem that the overall effect is poor when using the door and window due to the additional screen window outside the window frame in the traditional case.

[0041] Furthermore, the width of the window frame heat insulation strip 13 and the window sash heat insulation strip 16 in the horizontal direction is 64 mm.

[0042] Among them, in practical applications, the present application significantly increases the area of the heat insulation region by setting the horizontal widths of the window frame heat insulation strip 13 and the window sash heat insulation strip 16 to 64 mm. This design effectively reduces heat conduction and improves the heat insulation performance of the entire window structure. The wider heat insulation strip can not only block the heat bridge between metal profiles but also provides a larger filling space for heat insulation materials, further enhancing the heat insulation effect.

[0043] In practical applications, the 64-mm-wide heat insulation strip can accommodate more heat insulation materials, such as polyurethane foam or other high-performance heat insulation materials. These materials can be selected according to different climate conditions and building requirements to achieve the best heat insulation effect. Compared with the relatively narrow heat insulation strips commonly used in traditional window designs, the use of a 64-mm-wide heat insulation strip in the present application can not only effectively reduce heat loss but also maintain the aesthetics and practicality of the window. By optimizing the size of the heat insulation strip, the present application successfully achieves the goal of ultra-low energy consumption while ensuring the functionality of the window.

[0044] Further, the window sash is provided with a first window sash glass 110 and a second window sash glass 120 at intervals in the vertical direction. A mullion 21 is provided between the first window sash glass 110 and the second window sash glass 120. A fixing pressing strip 111 for fixing the first window sash glass 110 and a mounting cover plate 113 for covering the fixing pressing strip 111 are provided on the side of the mullion 21 close to the interior. The fixing pressing strip 111 and the mounting cover plate 113 are fixedly connected by a buckle 112.

[0045] Among them, two spaced window sash glasses are provided in the window sash, and a mullion 21 is provided between them, further improving the heat insulation performance of the window sash. The fixing pressing strip 111 provided on the side of the mullion 21 close to the interior is used to fix the first window sash glass 110 to ensure the stability of the glass installation. The mounting cover plate 113 covers the fixing pressing strip 111, enhancing the aesthetics of the window sash. The fixing pressing strip 111 and the mounting cover plate 113 are fixedly connected by a buckle 112, which is convenient for installation and disassembly and at the same time ensures the firmness of the connection.

[0046] Specifically, the spaced arrangement of the first window sash glass 110 and the second window sash glass 120 in the vertical direction forms an air layer, which can effectively block heat transfer and further improve the heat preservation and insulation performance of the window sash. The mullion 21, as a support structure, not only connects the two window sash glasses but also provides a foundation for installing the fixing pressing strip 111 and the mounting cover plate 113. The design of the fixing pressing strip 111 ensures the stable installation of the first window sash glass 110 and prevents the glass from loosening or falling off. The mounting cover plate 113 cleverly covers the fixing pressing strip 111, making the overall structure more beautiful.

[0047] The buckle 112 is arranged on the fixed pressure line 111, and the installation cover plate 113 is provided with a concave hole that cooperates with the buckle 112. By inserting the buckle 112 into the concave hole for fixation, the fixed pressure line 111 and the installation cover plate 113 are connected, which not only simplifies the installation process but also facilitates later maintenance and replacement. When it is necessary to replace the glass or perform cleaning and maintenance, the installation cover plate 113 can be easily disassembled, and the operation is convenient and fast. At the same time, the connection of the buckle 112 also ensures sufficient connection strength to ensure that the installation cover plate 113 will not loosen or fall off during daily use.

[0048] In traditional windows, the components for fixing the glass are often exposed outside, affecting the overall aesthetics. In this application, by setting the installation cover plate 113, the fixed pressure line 111 is effectively blocked, and there is no pressure line or middle stile without reinforcement on the indoor viewing surface. The viewing surface line is simple, smooth and beautiful, enhancing the overall aesthetic feeling of the product.

[0049] Furthermore, the upper surface of the fixed pressure line 111 is a plane, the upper surface of the installation cover plate 113 is a plane and is flush with the upper surface of the fixed pressure line 111 in the vertical direction, and the side surface of the installation cover plate 113 close to the indoor side is a plane and is flush with the side surface of the middle stile 21 close to the indoor side.

[0050] Among them, the upper surface of the fixed pressure line 111 is designed as a plane, which provides a flat installation foundation for the installation cover plate 113. The upper surface of the installation cover plate 113 is also designed as a plane and is flush with the upper surface of the fixed pressure line 111 in the vertical direction. This design ensures the visual continuity and flatness of the entire structure. In addition, the side surface of the installation cover plate 113 close to the indoor side is also designed as a plane and is flush with the side surface of the middle stile 21 close to the indoor side, further enhancing the consistency and aesthetic feeling of the overall structure.

[0051] Furthermore, the window sash also includes a window sash pressure line 17, an outer glass rubber strip 19 and an inner glass rubber strip 18. The outer glass rubber strip 19 is arranged on the side of the second window sash glass 120 close to the outdoor side, and the inner glass rubber strip 18 is arranged on one side of the outer glass rubber strip 19, so that the second window sash glass 120 is fixed between the outer window sash profile 14 and the inner window sash profile 15;

[0052] The window sash pressure line 17 is arranged between the outer window sash profile 14 and the outer glass rubber strip 19 to form a hidden sash structure.

[0053] Among them, the outer glass rubber strip 19 and the inner glass rubber strip 18 are respectively arranged on both sides of the second window sash glass 120, clamping and fixing the glass between the outer window sash profile 14 and the inner window sash profile 15 to ensure the stability and sealing performance of the glass installation. The window sash pressure line 17 is arranged between the outer window sash profile 14 and the outer glass rubber strip 19, that is, the window sash pressure line 17 cannot be seen from the indoor direction. This setting not only enhances the fixing effect of the glass but also realizes the hidden sash structure, improving the aesthetics of the window.

[0054] Specifically, the outer glass seal strip 19 is usually made of materials with good weather resistance and excellent elasticity, such as EPDM rubber or silicone. The outer glass seal strip 19 is in direct contact with the second sash glass 120, playing a role in preliminary fixation and sealing. The inner glass seal strip 18 can be made of materials with higher hardness, such as PVC or ABS plastic, and it cooperates with the outer glass seal strip 19 to form a stable clamping structure. The sash pressing strip 17 can be made of aluminum alloy or plastic steel, and its design needs to consider the cooperation with the outer sash profile 14 to achieve the hidden sash effect.

[0055] During the installation process, first place the second sash glass 120 on the outer sash profile 14, and then install the outer glass seal strip 19. Next, snap the sash pressing strip 17 into the slot reserved in the outer sash profile 14 so that it closely adheres to the outer glass seal strip 19. Finally, install the inner glass seal strip 18 to firmly fix the glass in the sash structure. This installation sequence ensures the stability and sealing of the glass.

[0056] Furthermore, it also includes a screen sash structure, which at least includes a first screen sash profile 1141 and a second screen sash profile 1142. The first screen sash profile 1141 is arranged on the side of the mullion 21 close to the outdoors, and the second screen sash profile 1142 is arranged on the outer frame profile 11. The first screen sash profile 1141 and the second screen sash profile 1142 are arranged at intervals in the vertical direction, and a screen mesh 118 is arranged in the interval area.

[0057] Among them, the first screen sash profile 1141 is arranged on the side of the mullion 21 close to the outdoors, using the existing mullion structure as a support point without additional installation space. The second screen sash profile 1142 is arranged on the outer frame profile 11, enabling the screen sash to closely cooperate with the window frame to ensure stability and sealing. The two screen sash profiles are arranged at intervals in the vertical direction to form a frame structure, providing an installation space for the screen mesh 118. The screen mesh 118 is arranged in the interval area between the first screen sash profile 1141 and the second screen sash profile 1142 and is fixed by the screen mesh pressing strip 117. On the side of the screen mesh pressing strip 117 close to the outdoors, a screen mesh seal strip 116 and a screen mesh pressing line 115 are also arranged in sequence for fixing and sealing the screen mesh 118. This design enables the screen sash structure to completely cover the window opening, effectively blocking mosquitoes from entering the room. Through this integrated design, the installation and disassembly of the screen sash structure become more convenient, improving the flexibility of use. At the same time, since the screen sash structure is closely combined with the passive window main structure without an additional frame structure, the overall structural stability and durability are also improved.

[0058] Compared with the traditional additional external window screens or retractable window screens, the integrated screen structure of the present application avoids the possible impact on the appearance of the window during the installation of traditional window screens and maintains the overall aesthetics of the window. Secondly, the integrated design makes the screen structure an integral part of the window structure, improving the stability and durability of the overall structure. Moreover, this design simplifies the installation and disassembly process of the screen structure, enhancing the convenience of use, and users can easily operate the screen structure as needed.

[0059] Among them, in order to better prevent mosquitoes and insects, screen slots 211 are provided in the first screen profile 1141 and the second screen profile 1142. The screen slots 211 are used to install the screen 118. The screen slots 211 adopt a deep groove design, which can be compatible with two configurations of 304 diamond mesh and high-transparency nylon mesh, providing users with more options for the configuration of the screen 118.

[0060] Furthermore, the first screen profile 1141 is arranged at the lower position on the outdoor side of the mullion 21. The side of the first screen profile 1141 close to the outdoor is a flat surface and is flush with the flat surface of the mullion 21 on the outdoor side;

[0061] The second screen profile 1142 is arranged at the upper position on the outdoor side of the outer frame profile 11. The side of the second screen close to the outdoor is a flat surface and is flush with the flat surface of the outer frame profile 11 on the outdoor side.

[0062] Among them, by reasonably setting the positions of the first screen profile 1141 and the second screen profile 1142, the flat and beautiful appearance of the screen structure is achieved. Specifically, the first screen profile 1141 is arranged at the lower position on the outdoor side of the mullion 21, and the side of the first screen profile 1141 close to the outdoor is a flat surface, which is flush with the flat surface of the mullion 21 on the outdoor side. This setting method makes the first screen profile 1141 and the mullion 21 form an integral whole visually, avoiding protrusions or depressions and improving the overall aesthetics. At the same time, the second screen profile 1142 is arranged at the upper position on the outdoor side of the outer frame profile 11. The side of the second screen profile 1142 close to the outdoor is a flat surface and is flush with the flat surface of the outer frame profile 11 on the outdoor side. This setting method makes the second screen profile 1142 and the outer frame profile 11 form an integral whole visually, also avoiding protrusions or depressions and further improving the overall aesthetics.

[0063] Through this design, the first screen profile 1141 and the second screen profile 1142 form a flat appearance with the window frame and the mullion 21, not only improving the aesthetics of the window, but also being conducive to reducing dust accumulation and facilitating cleaning and maintenance.

[0064] Furthermore, a detachable hinge structure 23 is provided on one side of the screen window structure, and a child safety lock 26 is provided on the other side.

[0065] Among them, the detachable hinge structure 23 increases the flexibility and maintainability of the screen window, allowing the screen window to open and close easily, while facilitating cleaning and maintenance. This not only ensures the normal use function of the screen window, but also improves the overall practicality of the window. The child safety lock 26 significantly enhances the safety performance of the window, effectively preventing children from accidentally opening the screen window and reducing the risk of children falling in high-rise buildings. At the same time, adults can still operate it easily without affecting normal use.

[0066] Specifically, one side of the hinge structure 23 is directly installed on the outer frame outer profile 11 through an ST4.2X25 pan head screw 24, and the other side of the hinge is fixed on the second screen window profile 1142 through an ST4.2×15 countersunk head screw 25, and can be disassembled and installed at any time, facilitating maintenance and repair. Through the detachable hinge structure 23, the user is allowed to easily disassemble the screen window when needed, facilitating thorough cleaning or replacement of damaged parts. The detachable feature of the hinge structure 23 also makes the installation and adjustment of the screen window structure simpler, contributing to the extension of the service life of the screen window structure. In practical applications, high-quality stainless steel or aluminum alloy materials can be selected to make the hinge to ensure its durability and rust resistance.

[0067] The child safety lock 26 usually adopts a dual unlocking mechanism, at least including a lock seat 28 fixed on the outer frame outer profile 11 with screws, and two different parts need to be operated simultaneously to open the screen window. This design is difficult for children, but adults can operate it easily. The safety lock can adopt a hidden design, which does not affect the aesthetics of the window while maintaining the convenience of operation.

[0068] Therefore, the technical solution of this application effectively solves the safety and convenience problems in the use of the screen window by respectively providing a detachable hinge and a child safety lock 26 on both sides of the screen window structure. The detachable hinge plays an important role in daily use, allowing the screen window to open and close flexibly to meet the ventilation needs. When cleaning or maintenance is required, the user can easily disassemble the screen window, greatly improving the convenience of maintenance. This design not only extends the service life of the screen window, but also reduces the maintenance cost.

[0069] Furthermore, a magnetic attraction structure is provided between the outer frame outer profile 11 and the screen window structure.

[0070] Specifically, to cooperate with the child safety lock 26, an outer frame magnetic strip 29 can be embedded on the outer profile 11 of the outer frame, and a screen magnetic strip 210 can be provided at the corresponding position of the screen structure. An adjustable magnetic attraction device can also be used to adapt to different usage requirements and environmental conditions. The strength of the magnetic attraction structure can be adjusted according to the weight and usage frequency of the screen structure to ensure the stability of the connection and the convenience of use. The design of this magnetic attraction structure realizes the stable connection of the screen through magnetic force, without complex mechanical connectors, simplifying the overall structure. Moreover, the magnetic attraction structure allows the screen structure to be installed and disassembled quickly and conveniently. Users can easily adsorb the screen structure onto the outer profile 11 of the outer frame or easily remove it when needed, greatly improving the flexibility and convenience of use.

[0071] In addition, the magnetic attraction structure also provides an appropriate sealing effect. When the screen structure is adsorbed onto the outer profile 11 of the outer frame, the magnetic force can ensure a tight fit between the two, helping to prevent dust, insects, etc. from entering the room and improving the sealing performance of the window. At the same time, the magnetic attraction structure allows the screen structure to have a certain degree of small movement while maintaining stability, which helps to adapt to the expansion and contraction of materials caused by temperature changes, improving the adaptability and service life of the window.

[0072] Traditional mechanical connections usually require the use of fixing parts such as screws and buckles. Not only are the installation and disassembly cumbersome, but they are also prone to loosening or damage due to long-term use. The magnetic attraction structure does not require these additional mechanical parts, reducing the number of components and simplifying the overall structure of the window, which is beneficial to improving the overall performance and durability of the window. At the same time, the use of the magnetic attraction structure also avoids the possible thermal bridge effect caused by the presence of mechanical connectors, further enhancing the heat insulation and sound insulation performance of the window.

[0073] Furthermore, the upper window frame heat insulation strip 13 is provided with a first buffer structure 31, and the lower window sash heat insulation strip 16 is provided with a second buffer structure 33.

[0074] Among them, by providing the first buffer structure 31 on the upper window frame heat insulation strip 13 and the second buffer structure 33 on the lower window sash heat insulation strip 16, the buffer performance of the window can be effectively improved. The setting of these two buffer structures can reduce the impact force when the window is opened and closed, reduce the friction between the window frame and the window sash, and thus extend the service life of the window.

[0075] Specifically, the first buffer structure 31 is provided on the upper window frame heat insulation strip 13, which can buffer the contact between the window sash and the window frame when the window sash is closed, reducing the impact force. The second buffer structure 33 is provided on the lower window sash heat insulation strip 16, which can buffer the contact between the window sash and the window frame when the window sash is opened, also playing a role in reducing the impact force. The synergistic effect of these two buffer structures can effectively protect the window structure, reduce wear, and extend the service life of the window.

[0076] The first buffer structure 31 can be made of an elastic material, such as rubber or silica gel, etc., and is installed at an appropriate position on the upper window frame heat insulation strip 13. When the window sash is closed, this elastic material can absorb part of the impact force and reduce the direct collision between the window sash and the window frame. Similarly, the second buffer structure 33 can also be made of a similar elastic material and is installed on the lower window sash heat insulation strip 16. When the window sash is opened, this buffer structure can slow down the opening speed of the window sash and avoid a violent collision between the window sash and the window frame.

[0077] The above are only embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
