Description

Technical Field

[0001] This utility model relates to the field of casement window sealing, heat insulation, sound insulation and drainage technology, and in particular to an innovative casement window sealing, heat insulation, sound insulation and drainage system solution. Background Technology

[0002] Existing casement window drainage systems mostly use direct drainage or concealed drainage holes. In traditional designs, the drainage holes in the frame are exposed when the window sash is opened, which not only fails to effectively prevent insects from entering but also fails to block pollutants such as sandstorms and smog. Current technology only provides drainage holes on the vertical edges of the window frame.

[0003] However, there is a gap between these drainage holes and the rain guard strip. This gap was originally designed to improve drainage efficiency. However, it also allows dust to easily accumulate and becomes a habitat for mosquitoes. The new innovation creates an interdependent structure for these elements, including an insulated cavity and a concealed drainage system. Figure 2 As shown, this illustrates the relationship between the window frame vertical edge, drainage holes, and rain guard strip in existing casement window technology.

[0004] Limitations of existing drainage systems

[0005] Drainage holes are prone to clogging: Traditional drainage holes have a simple design, and dust and debris can easily accumulate and cause blockages, especially in windy and sandy areas where frequent cleaning is required.

[0006] Weak ability to prevent backflow of rainwater: In strong winds, some drainage holes are prone to backflow of rainwater due to structural defects, which may even cause howling noise.

[0007] Poor sound insulation: Existing casement windows have poor sound insulation at the joints.

[0008] Insufficient drainage efficiency: During heavy rain, a single drainage hole design may not be able to drain accumulated water in time, resulting in water accumulation on the windowsill or inside the profile.

[0009] Weak points in waterproofing: The connection between the window frame and the wall, and the installation holes of hardware are prone to water seepage due to cracks in the sealant or inadequate filling. Utility Model Content

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model provides an innovative solution for a casement window sealing, heat insulation, sound insulation, and drainage system. Through the synergistic action of the window frame assembly, window frame assembly, transition cavity assembly, glass panel, rainproof sealing assembly, and drainage mechanism, a multi-layered rainproof and drainage system is constructed. The transition cavity assembly is preferably made of PVC material. The sliding hinge connection between the window frame and window frame enables flexible opening and closing of the casement window, while the rainproof sealing assembly effectively prevents rainwater infiltration through the tight fit between the sealing strip and the profile. The drainage mechanism utilizes the drainage holes on the window frame profile, the transition cavity assembly, and the mesh structure of the drainage cover to form a directional flow channel, quickly draining infiltrated water and preventing water accumulation. This design also significantly improves the overall performance of the casement window. By introducing a new structural rainproof sealing strip and a combined cavity made of PVC material profile on the basis of existing thermally broken profiles, we have improved the heat insulation performance, sealing, and sound insulation functions of the window frame profile.

[0021] At the same time, this technology is of great significance for improving and enhancing the performance of old casement windows, allowing people to achieve the same effect as new windows at home without having to remove old windows and replace them with new ones.

[0022] This system solution can effectively block sandstorms and smog in Northwest and North China, as well as rain and clear skies in the South. Therefore, this solution enables all of Hetianxia's built-in casement windows to have drainage and rain-blocking functions.

[0023] The new technology takes into account specific environmental conditions in China, such as the need to prevent sandstorms in the Northwest and North China regions, and the need to prevent moisture backflow in the southern regions to bring back blue skies.

[0024] The outer edge of the window frame is reinforced with a transition profile cavity on the existing single-sided aluminum material. A concealed drainage system is installed between these cavities. The number of drainage cavities and whether they are located in the middle or at both ends of the transition profile cavity can be determined according to the local rainfall conditions. The inner perimeter of the outer edge of the window frame is reinforced with a transition profile cavity that fits tightly against the rainproof strip, forming a complete system that provides insulation, waterproofing, sealing, and soundproofing.

[0025] Its beneficial effects are reflected in:

[0026] Overall performance improvement: Based on traditional thermal break profiles, the application of a new type of rainproof sealing strip and PVC material profile to make a combined cavity significantly enhances the thermal insulation, sealing and sound insulation performance of the window frame, adapting to the needs of multiple climate regions;

[0027] Technical compatibility: It can upgrade old casement windows and achieve the same drainage and sealing effects as existing new windows without replacing the entire window, thus reducing user costs;

[0028] Environmental adaptability: The sloped design of the rainproof sealing strip, combined with the trapezoidal heat insulation cavity, can resist sandstorms, smog and heavy rainfall, making it suitable for rainy areas in Northwest, North China and South China, achieving universal applicability across all regions;

[0029] This solution achieves a three-dimensional breakthrough through structural innovation, material composites, and scenario adaptation, reconstructing the drainage and sealing logic of casement windows, thus not only solving traditional pain points, but also making it a core technology for the renovation of existing buildings due to its economic efficiency and universality.

[0041] The present invention provides the following embodiments.

[0042] Example 1

[0043] This utility model provides an innovative solution for a casement window sealing, heat insulation, sound insulation, and drainage system, such as... Figure 1 As shown, the assembly includes: a window frame assembly 1, a window frame assembly 2, a transition cavity assembly 3, a glass panel 30, a rainproof sealing assembly 4, and a drainage mechanism 5. The rear top of the window frame assembly 1 is slidably hinged to the window frame assembly 2 along the front-rear direction. The transition cavity assembly 3 is fixedly provided on the top left side of the window frame assembly 1. The vertical glass panel 30 is fixedly installed at the top center of the window frame assembly 2. Rainproof sealing assemblies 4 are provided at the connection between the window frame assembly 1 and the window frame assembly 2 and at the connection between the window frame assembly 2 and the glass panel 30. The window frame assembly 1, the window frame assembly 2, and the transition cavity assembly 3 together constitute the drainage mechanism 5.

[0044] The working principle and beneficial effects of the above technical solution are as follows:

[0045] This invention constructs a multi-layered rainproof and drainage system through the synergistic action of the window frame assembly 1, window frame assembly 2, transition cavity assembly 3 (preferably made of PVC material), glass panel 30, rainproof sealing assembly 4, and drainage mechanism 5. The sliding hinge connection between the window frame and window frame allows for flexible opening and closing of the casement window, while the rainproof sealing assembly 4 effectively prevents rainwater infiltration through the tight fit between the sealing strip and the profile. The drainage mechanism 5 utilizes the drainage holes 29 on the window frame profile, the mesh structure of the window frame transition cavity assembly 3, and the drainage cover 41 to form a directional flow channel, quickly draining infiltrated water and preventing water accumulation. This design also significantly improves the overall performance of the casement window. By introducing a novel structural rainproof sealing strip 20 and a transition profile 37 (preferably made of PVC material) combined cavity based on existing thermally broken profiles, we have improved the thermal insulation performance, sealing, and sound insulation functions of the window frame profile.

[0046] At the same time, this technology is of great significance for improving and enhancing the performance of old casement windows that have been installed. It allows windows to achieve the same sealing, heat preservation, sound insulation and drainage effects as new windows without replacing or removing them.

[0047] This system solution can effectively block sandstorms and smog in Northwest and North China, as well as rain and clear skies in the South. Therefore, this solution enables all of Hetianxia's built-in casement windows to have drainage and rain-blocking functions.

[0048] The new technology takes into account specific environmental conditions in China, such as the need to prevent sandstorms in the Northwest and North China regions, and the need to prevent moisture backflow in the southern regions to bring back blue skies.

[0049] The outer edge of the window frame is equipped with a transition profile 37 (preferably PVC profile) cavity on the existing single-sided aluminum material. A concealed drainage system fitting is installed in the cavity. The drainage fittings in the middle and at both ends of the transition profile 37 cavity can be configured according to the local rainfall. The transition profile 37 cavity is added to the inner perimeter of the outer edge of the window frame and is closely attached to the rainproof strip to form a complete system with heat preservation, waterproofing, sealing and sound insulation functions.

[0050] Its beneficial effects are reflected in:

[0051] Overall performance improvement: Based on traditional thermal break profiles, a new drainage path is formed by the application of a new type of rainproof sealing strip 20 and transition profile 37 combined cavity, the window frame assembly and transition cavity assembly 3, the transition cavity assembly 3 and drainage cover 41, and the combination mechanism of transition profile 37 cavity and rainproof sealing strip 20.

[0052] Technical compatibility: It can achieve the same technical effect as existing new windows without replacing old ones, reducing user costs;

[0053] Environmental adaptability: The rainproof sealing strip 20 designed with inclined surface 21, together with the trapezoidal heat insulation cavity 28, can resist sandstorms, smog and heavy rainfall, and is suitable for rainy areas in Northwest, North China and South China, achieving universal applicability across all regions.

[0054] Specific innovations:

[0055] I. Technological Breakthroughs and Core Innovations

[0056] Innovative Design: A new type of rain-resistant sealing strip 20 (elastic seal, adaptable to various deformations) is combined with a transition profile 37 to form a dynamic sealing barrier. The frame drain outlet features a concealed guide channel design, ensuring complete sealing when the window is closed and maintaining an internal seal when open, preventing backflow of contaminants.

[0057] Upgraded thermal break profile: Based on the original thermal insulation layer, rubber strips and transition cavity components are embedded to form a multi-layer barrier structure, improving the efficiency of heat conduction blocking.

[0058] Composite sealing mechanism: The combination of the flexibility of the rubber strip and the rigidity of the transition profile 37 enhances wind pressure resistance and air tightness, and improves sound insulation performance to over 35dB.

[0059] II. Performance Improvement and Functionality Expansion

[0060] 1. Comprehensive environmental adaptability

[0061] Northwest Sandstorm: The dual filtration of the flow channel and rubber strip reduces the amount of particulate matter entering the room, and the anti-permeability design of the PVC cavity reduces the risk of window frame corrosion.

[0062] North China smog: The sealed structure blocks PM2.5 particles, and combined with the electrostatic adsorption properties of the rubber strips, it further purifies the air entering the room.

[0063] During the humid season in southern China: the drainage system is optimized to guide condensate flow, preventing water accumulation that could lead to profile corrosion, and the hygroscopicity of the PVC cavity reduces the probability of condensation.

[0064] 2. Multi-scenario compatibility

[0065] Built-in integrated screen: The drainage outlet design is linked to the opening and closing of the screen, enabling the screen and sealing system to operate synchronously without additional modifications.

[0066] Upgrade and adaptation of old windows: Old casement windows can be upgraded in performance without disassembling the window by replacing the rubber strips and cavity modules, reducing costs by 60%.

[0067] III. Economic viability and industry value

[0068] 1. Lifecycle cost optimization

[0069] Maintenance costs: The rubber strips can be partially replaced, avoiding the need for the entire window to be scrapped and extending the service life to more than 20 years.

[0070] Energy-saving benefits: Improved thermal insulation performance can reduce air conditioning energy consumption.

[0071] 2. Driving Forces of Industry Upgrading

[0072] Technological iteration: Breaking away from the traditional "window replacement and upgrade" model, driving the industry to shift from "product sales" to "service-oriented transformation".

[0073] Environmental contribution: Reduces construction waste generated from the dismantling of old windows, aligning with green building standards.

[0074] IV. User Value and Market Prospects

[0075] User experience: Waterproof and dustproof rating reaches IP65, with no risk of indoor leakage during heavy rain.

[0076] The quiet design (≤30dB) improves sleep quality, making it especially suitable for high-rise residential buildings in cities.

[0077] In summary, this solution achieves a three-dimensional breakthrough through structural innovation, material composites, and scenario adaptation, reconstructing the drainage and sealing logic of casement windows. It not only solves traditional pain points, but its economic efficiency and universality make it a core technology for the renovation of existing buildings. It is expected to drive the industry from "passive defense" to "active protection" and become an important technological paradigm in the field of green building.

[0080] The top right of the first window frame profile 6 is fixedly connected to a T-shaped hook 15 along the front-back direction. The left side of the second window frame profile 7 is symmetrically provided with two dovetail grooves 17 along the front-back direction. The dovetail grooves 19 and 17 are connected by two sets of thermal insulation strips 18. The top of the thermal insulation strip 18 has a pair of second T-shaped grooves 19 along the front-back direction. The top left of the second window frame profile 7 is fixedly connected to a T-shaped hook 16. The top of the second T-shaped groove 19 is located between the T-shaped hooks 15 and 16 and a rainproof sealing strip 20 along the front-back direction is fixedly installed. The top left of the rainproof sealing strip 20 has a slope 21 that is higher on the left and lower on the right.

[0081] The working principle and beneficial effects of the above technical solution are as follows:

[0082] This embodiment achieves dual optimization of sealing performance and structural strength through the double-profile structure of the window frame assembly 1 and the nested thermal break strip design. The first window frame profile 6 and the second window frame profile 7 are connected to the thermal break strip 18 via dovetail groove 19 and dovetail groove 27, forming a stable frame structure. Simultaneously, the second T-groove 19 at the top of the thermal break strip 18 provides an installation position for the rainproof sealing strip 20. The inclined surface 21 of the rainproof sealing strip 20 guides rainwater outwards and forms a double sealing barrier with the T-hook 15 and T-hook 26. Its beneficial effects are reflected in:

[0083] Enhanced sealing performance: The combination of the rainproof sealing strip 20 and the hook structure effectively prevents rainwater from seeping through the window frame joints, extending the service life of the profiles;

[0084] Improved thermal performance: Thermal insulation strip-18 reduces heat conduction of the profile, and combined with closed cavity-8, it reduces energy loss, meeting energy-saving building standards;

[0085] Ease of installation: The modular design of dovetail grooves and T-slots simplifies the profile assembly process and improves production efficiency.

The first window frame profile 22 is located on the upper right side of the first window frame profile 6, and the second window frame profile 23 is located above the second window frame profile 7. A pair of dovetail grooves 24 are symmetrically opened at the bottom right end of the first window frame profile 22. A pair of dovetail grooves 25 are fixedly opened at the left end of the second window frame profile 23 corresponding to the position of the dovetail grooves 24. The upper dovetail grooves 24 and 25 are nested and connected by a thermal insulation strip 26, and the lower dovetail grooves 24 and 25 are nested and connected by a thermal insulation strip 27.

When the casement window is closed, the left side of the thermal insulation cavity 28 is tightly fitted against the right side of the rainproof sealing strip 20.

[0088] The working principle and beneficial effects of the above technical solution are as follows:

[0089] Window frame assembly 2 adopts a double-profile nested thermal break design, forming a multi-layered thermal insulation structure through thermal break strips 26 and 27 and the trapezoidal thermal insulation cavity 28. When the casement window is closed, the left side of the thermal insulation cavity 28 and the right side of the rainproof sealing strip 20 are tightly fitted together, forming an airtight barrier. At the same time, the trapezoidal structure enhances wind pressure resistance. Its beneficial effects are reflected in:

[0090] Breakthrough in thermal performance: The trapezoidal heat insulation cavity 28 reduces heat convection, and together with sealing strip 1 45 and sealing strip 2 47, it achieves a seamless seal between the glass plate 30 and the profile, reducing energy consumption;

[0091] Enhanced structural stability: The nested connection between dovetail groove 324, dovetail groove 425 and thermal insulation strip improves the window frame's resistance to deformation and adapts to the high wind pressure environment of high-rise buildings;

[0092] Optimized noise reduction: The multi-layered sealed structure reduces noise transmission and improves indoor comfort.

The bottom right of the transition profile 37 is fixedly connected to a snap-fit ​​connector 1 39, which is nested with a snap hook groove 13. The top left side of the transition profile 37 is fixedly connected to a snap-fit ​​connector 2 40, which is nested with a snap hook groove 2 14.

[0096] The left end of the snap-fit ​​connector 40 is pressed against the right side of the extension sidewall 10, and the right side wall of the transition profile 37 is pressed against the left side wall of the rainproof sealing strip 20.

[0098] The drainage mechanism 5 constructs a three-stage drainage path through the combined design of the drainage holes 29 in the window frame profile, the transition cavity assembly 3, and the drainage cover 41. Rainwater seeps in through the gaps at the sealed connection between the window screen frame 49 and the first window frame profile 22, is guided by the rain-blocking sealing strip 20 to the top of the drainage cover 41, flows through several drainage mesh holes 42 into the bottom space of the transition profile 37, and finally exits through the drainage holes 29. The rain-blocking sealing strip 20, the transition profile 37, and the thermal insulation cavity 28 are all tightly fitted face-to-face, significantly increasing the sealing, rain-blocking, thermal insulation, and sound insulation performance. Its beneficial effects are reflected in:

[0099] Improved drainage efficiency: Directional flow channels prevent water accumulation and reduce the risk of profile corrosion;

[0100] Insect-proof and clog-proof design: The removable drainage cover 41 makes it easy to clean up debris, and the mesh structure prevents insects from entering;

[0101] Enhanced sealing: The transition profile 37 is tightly connected to the window frame profile through snap-fit ​​connector 39 and snap-fit ​​connector 40, forming a double seal to prevent rainwater backflow.

A screen hook 50 is embedded in the top of the screen frame 49. A T-shaped groove 3 51 is fixedly opened on the top right side of the screen hook 50. A sealing strip 3 52 is embedded in the T-shaped groove 3 51. The right end of the sealing strip 3 52 is pressed against the first window frame profile 6. An extended side wall 3 53 is fixedly provided at the bottom of the second window frame profile 23. A T-shaped groove 4 54 is opened on the left side of the extended side wall 3 53. A sealing strip 4 55 is embedded in the T-shaped groove 4 54. The left end of the sealing strip 4 55 is pressed against the right end of the second window frame profile 7 when the casement window is closed.

[0105] The working principle and beneficial effects of the above technical solution are as follows:

[0106] The rainproof sealing assembly 4 achieves all-around sealing of the glass panel 30 and the window screen frame 49 through the synergistic action of multiple sealing strips and the profile. Sealing strip one 45 and sealing strip two 47 clamp the glass panel 30, sealing gasket three 48 fills the gap between the thermal insulation strip and the glass, and sealing strip three 52 and sealing strip four 55 seal the joint between the window screen frame 49 and the window frame, respectively. Its beneficial effects are reflected in:

[0107] Waterproof and dustproof upgrade: Five sealing barriers completely isolate rainwater, sand and dust and smog, extending the service life of screens and profiles;

[0108] Air tightness optimization: The nested design of the T-slot and sealing strip reduces air infiltration and improves thermal insulation performance;

[0109] Convenience of maintenance: The sealing strip can be replaced independently, reducing the cost of later maintenance.
