Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a novel energy-saving multi-seal structure for doors and windows. Background Technology

[0002] In terms of door and window materials, aluminum alloys are widely used due to their high strength, corrosion resistance, resistance to deformation, and long service life. However, traditional ordinary aluminum alloy doors and windows have poor thermal insulation performance due to the inherent high thermal conductivity of the material, making it difficult to meet the increasingly stringent energy-saving standards of modern buildings. To solve this problem, thermally broken aluminum alloy technology has emerged. By using thermal break strips to separate the aluminum profiles on the indoor and outdoor sides, the heat conduction path is effectively blocked, significantly improving the thermal insulation performance of doors and windows, and has become the mainstream technology in the current energy-saving door and window market.

[0003] Traditional thermally broken aluminum alloy doors and windows typically use single or double sealing strips for sealing, and their structure is relatively simple.

[0004] However, existing door and window structures still have the following shortcomings in practical use: Traditional single or double sealing structures are prone to deformation between the window sash and frame when facing strong wind pressure. This can lead to uneven compression or gaps in the sealing strip, significantly reducing airtightness and watertightness. Especially in high-rise buildings or coastal areas with frequent rain and wind, rainwater can easily penetrate the sealing barrier under wind pressure, causing indoor leaks.

[0005] The four corners of doors and windows are where the profiles are joined. Traditional corner connections often use simple screws or pins for fixing, which have limited strength and are prone to loosening and misalignment after long-term use, compromising the continuity and clamping force of the sealing strips. At the same time, the gaps at the corner joints are also a common leakage point. Even with sealing strips, moisture can seep in through the tiny gaps between the profile joints.

[0006] Although some doors and windows have drainage holes, they lack a systematic drainage cavity design. A small amount of rainwater entering the gap between the frame and sash cannot be effectively managed and drained, easily forming water accumulation at the bottom of the window frame. Prolonged soaking will not only corrode the hardware, but may also seep into the interior wall through capillary action. Utility Model Content

[0007] This utility model provides a novel energy-saving multi-seal structure for doors and windows, aiming to solve the problems mentioned in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A novel energy-saving multi-seal structure for doors and windows includes: window frame; An inward-opening window sash connected to the window frame via a hinge; The window frame and the inward-opening window sash are both made of thermally broken aluminum profiles. The corners of the inward-opening window sash and the corners of the window frame are connected by corner brackets placed in the profile cavity to form a high-rigidity frame and sash structure, providing a stable and reliable structural foundation for the window sealing system. The inward-opening window sash is equipped with double-glazed glass, which is fixed by aluminum alloy clamps set on the inner and outer sides of the inward-opening window sash. An EPDM rubber strip is provided at the closing joint between the window frame and the inward-opening window sash. The EPDM rubber strip is installed on the outside of the inward-opening window sash and is used to form a continuous and effective outer seal with the window frame when the inward-opening window sash is closed. At the point where the window frame and the inward-opening window sash meet, along the direction from the outside to the inside, intermediate seals and inner seals are sequentially provided, together forming a multi-level progressive sealing system.

[0009] Preferably, the intermediate seal includes an intermediate sealing strip disposed on the window frame, and an equal pressure cavity is formed between the EPDM rubber strip and the intermediate sealing strip. A drainage hole communicating with the equal pressure cavity is provided on the lower horizontal frame profile of the window frame, and the lower horizontal frame profile is inclined at the drainage hole.

[0010] Preferably, the corner bracket is an injection-type corner bracket. After the corner bracket is assembled with the profile cavity, the gap between the corner bracket and the inner wall of the profile cavity is filled and sealed by the injection process to achieve integrated sealing and rigid connection.

[0011] Preferably, the side of the aluminum alloy pressure line is provided with a groove that matches the interior profile of the inward-opening window sash, and a sealing strip is provided between the insulating glass and the aluminum alloy pressure line, with the sealing strip located in the groove.

[0012] Preferably, the bottom of the insulating glass is supported on the lower horizontal frame of the inward-opening window sash by at least one glass gasket, providing support for the insulating glass and reserving a drainage gap.

[0013] Preferably, the profiles of the inward-opening window sash and window frame are multi-chamber structures to improve the overall heat insulation and sound insulation of the window.

[0014] The technical effects and advantages of this utility model are as follows: 1. This utility model establishes a multi-level, progressive defense system through the setting of three seals: outer, middle, and inner. More importantly, an isobaric chamber is formed between the middle and outer seals, and combined with a highly efficient drainage structure, it actively balances the indoor and outdoor wind pressure difference, effectively preventing rainwater from being "forced" into the room under high wind pressure. This fundamentally solves the technical problem of traditional sealing structures being prone to leakage in high wind and rain environments. Simultaneously, the high-rigidity frame and sash structure formed by the glue-injected corner brackets provides a solid structural guarantee for the long-term effective operation of the sealing system, ensuring excellent and durable water tightness and air tightness of the entire window.

[0015] 2. This utility model organically combines multiple aspects such as corner strength, multi-layer sealing, equal-pressure drainage, and glass installation methods. The glued corner brackets strengthen the structure and seal gaps; the aluminum alloy pressure lines installed on the indoor side eliminate the risk of leakage on the outdoor side at the source; and the scientific use of glass gaskets ensures smooth drainage inside the glass channel. These components work synergistically to comprehensively improve the sound insulation, heat insulation, waterproofing, and structural stability of the doors and windows, significantly enhancing the overall performance and long-term reliability of the product.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4A novel energy-saving multi-seal structure for doors and windows, comprising: Window frame 1; The inward-opening window sash 2 is connected to the window frame 1 via a hinge; Both the window frame 1 and the inward-opening window sash 2 are made of thermally broken aluminum profiles. The corners of the inward-opening window sash 2 and the corners of the window frame 1 are connected by corner brackets 3 placed inside the profile cavity, forming a high-rigidity frame-sash structure that provides a stable and reliable structural foundation for the window sealing system. The corner bracket 3 connection method, especially when combined with the subsequent adhesive injection process, can form a high-rigidity frame-sash structure that resists deformation caused by wind pressure, its own weight, or long-term use, thus providing a stable and reliable structural foundation for the entire window sealing system and ensuring that the sealing strip can be uniformly and continuously compressed.

[0020] The inward-opening window sash 2 is equipped with a double-glazed glass 4, which is fixed by an aluminum alloy pressure wire 5 set on the inner and outer sides of the inward-opening window sash 2. During installation, the double-glazed glass 4 is placed from the inside into the sash frame and then fixed by the aluminum alloy pressure wire 5, which is convenient and safe to operate.

[0021] An EPDM rubber strip 6 is provided at the closing joint between the window frame 1 and the inward-opening window sash 2. The EPDM rubber strip 6 is installed on the outside of the inward-opening window sash 2. When the inward-opening window sash 2 is closed, the EPDM rubber strip 6 will be tightly pressed against the outside of the window frame 1, forming the first line of defense, namely the outside seal, which can effectively block most of the rainwater and airflow.

[0022] At the point where the window frame 1 and the inward-opening window sash 2 meet, intermediate seals and inner seals are sequentially provided along the direction from the outside to the inside, forming a multi-level progressive sealing system that significantly improves the airtightness, watertightness, and sound insulation performance of the doors and windows.

[0023] To achieve watertightness, this structure utilizes the principle of an equal pressure chamber. As described above, the intermediate seal includes an intermediate sealing strip 7 installed on the window frame 1. When the window sash is closed, a relatively sealed cavity is naturally formed between the outer EPDM rubber strip 6 and the intermediate sealing strip 7. This cavity is the equal pressure chamber 8. A drainage hole 9 communicating with the equal pressure chamber 8 is provided on the lower horizontal frame profile of the window frame 1. The lower horizontal frame profile is inclined at the location of the drainage hole 9. The drainage hole 9 can be directly opened, or a weatherproof drainage cover can be added to the outside of the drainage hole 9 to prevent rainwater backflow in extreme weather conditions.

[0024] In windy or rainy conditions, a small amount of rainwater and airflow that has passed through the outer seal will enter the pressure equalization chamber 8. Since wind pressure also acts on the interior of the pressure equalization chamber 8, the air pressure inside and outside the chamber tends to balance, thus eliminating the pressure difference that forces rainwater into the room. At this time, the rainwater entering the pressure equalization chamber 8 naturally falls to the bottom of the chamber under gravity and is smoothly discharged outdoors through the drainage holes 9 on the lower horizontal frame profile of the window frame 1. To further optimize the drainage effect, the lower horizontal frame profile is designed with a sloped surface towards the outside at the location of the drainage holes 9, using the slope angle to guide the water flow and prevent water accumulation.

[0025] The corner bracket 3 is an injection-type corner bracket. After assembly with the profile cavity, the gap between the corner bracket 3 and the inner wall of the profile cavity is filled and sealed using an injection process, achieving an integrated seal and rigid connection. During assembly, the corner bracket 3 is first inserted into the profile cavity and mechanically fixed. Then, a special corner bracket adhesive is injected through the pre-drilled injection hole. The adhesive fills all the tiny gaps between the corner bracket 3 and the inner wall of the profile cavity. After the adhesive cures, the corner bracket 3 and the two profile sections form an integrated rigid connection, which not only greatly enhances the torsional strength and connection strength of the corner, but also further seals the corner joint gaps, achieving an integrated seal and minimizing the risk of water leakage at the corner.

[0026] The side of the aluminum alloy pressure line 5 is provided with a groove 10 that matches the interior profile of the inward-opening window sash 2, and a sealing strip 11 is provided between the insulating glass 4 and the aluminum alloy pressure line 5.

[0027] The bottom of the insulating glass 4 is supported on the lower horizontal frame of the inward-opening window sash 2 by at least one glass gasket 12, which provides support for the insulating glass 4 and leaves a drainage gap.

[0028] The gasket 12 not only distributes the weight of the insulated glass 4 and prevents stress concentration, but more importantly, it lifts the bottom of the glass to leave the necessary drainage gap, ensuring that water can flow smoothly to the drainage hole on the sash frame.

[0029] Both the inward-opening window sash 2 and the window frame 1 have multi-chamber structures in their profiles; the interior of the profile is divided into multiple small, non-interconnected chambers. The air chambers have good heat insulation and sound insulation properties, which can further reduce heat conduction and sound wave transmission, thereby significantly improving the overall thermal insulation and sound insulation performance of the window.

[0030] Although the multi-seal structure disclosed in this utility model is illustrated using an inward-opening window sash as an example, its design principles and core structure can be fully applied to other types of door and window products, such as outward-opening windows, inward-opening and tilt-and-turn windows, sliding doors, and casement doors. By simply adjusting the cross-section of the profile and the position of the sealing strip according to different opening methods, the same excellent sealing and energy-saving effects can be achieved.

[0031] In this embodiment, insulated glass 4 is used. To improve performance, it can be upgraded to triple insulated glass, laminated insulated glass, or insulated glass filled with inert gas to achieve more extreme heat insulation and sound insulation performance.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
