Description

Technical Field

[0001] This utility model specifically relates to a high-performance energy-saving system window, belonging to the field of system window technology. Background Technology

[0002] With the increasing demands for building energy conservation, windows, as an important component of the building envelope, directly affect the overall energy consumption of a building. System windows, as a high-performance energy-saving window, significantly improve the heat insulation, sound insulation, and sealing performance of windows through optimized structure and materials, becoming a key element in modern building energy-saving design. For example, Chinese Patent Publication No. CN215859712U discloses a type 901 glass fiber reinforced polyurethane high energy-saving system window, including a window sash and a window frame, and three layers of glass. The window frame is assembled from window frame profiles, with a right-side stop extending inward from the right end of the window frame profile. The sash frame is assembled from the sash frame profiles... The polyurethane system window, constructed by connecting multiple parts, is easy to assemble and offers better energy-saving and thermal insulation performance. However, existing system windows typically use a single thermal break strip or a simple combination of these strips. While these can block the thermal bridging effect to some extent, the overall structural strength is insufficient. Therefore, the spacing between the thermal breaks cannot be too large, otherwise the inner and outer window frames will separate, thus failing to guarantee the thermal insulation effect. Furthermore, a single thermal insulation material is difficult to achieve multi-layered and multi-path thermal blocking, resulting in a still significant thermal bridging effect and affecting energy-saving performance. In addition, under long-term use or extreme weather conditions, the sealing strips of existing window frames and sashes are prone to aging and deformation, leading to sealing failure and affecting the window's waterproof, dustproof, and soundproof performance. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a high-performance energy-saving system window. By increasing the distance between the thermal breaks, ensuring adequate thermal insulation at the thermal breaks, and achieving full sealing between the sash frame and the window frame, the system window achieves better energy-saving performance.

[0004] This utility model discloses a high-performance energy-saving system window, comprising a main frame, a sub-frame fixed to the inner side of the main frame, a sash frame sealed inside the sub-frame, and vacuum glass installed inside the sash frame. The main frame, sub-frame, and sash frame each include an inner thermal break frame and an outer thermal break frame. A sealing support unit is provided between the inner and outer thermal break frames, and a pressure sealing unit is provided between the sash frame and the sub-frame. The sealing support unit includes: The skeleton has a square wave structure in its transverse cross-section. Dovetail grooves are integrally formed on both sides of the skeleton along its length. A first aerogel felt is attached to the top and bottom surfaces of the skeleton. A second aerogel felt fills the enclosed space formed by the skeleton and the first aerogel felt. An edge seal, which is attached to the first aerogel felt, is engaged with the outside of the dovetail grooves. A first thermal insulation strip is attached to the side of the first aerogel felt that is away from each other. Multiple cavities are provided within the first thermal insulation strip. Both the edge seal and both sides of the first thermal insulation strip are engaged with the inner and outer thermal break frames. The press-fit sealing unit includes an upper heat insulation strip and a lower heat insulation strip disposed between the inner and outer thermal break frames of the fan frame; an isolation sealing strip is engaged at the top of the sub-frame; a first stepped protrusion is integrally formed at the bottom of the lower heat insulation strip; and a second stepped protrusion is integrally formed at the top of the isolation sealing strip to cooperate with the first stepped protrusion.

[0005] The main frame is assembled with the wall as a single unit. The main frame supports the secondary frame, which in turn supports the sash frame. Simultaneously, the secondary frame works with the sash frame to achieve a seal between the sash frame and the secondary frame. The sash frame is used to install vacuum glass, which provides thermal insulation between the interior and exterior. The sealing support unit is installed between the inner and outer thermal break frames, supporting both and achieving thermal insulation. Specifically, the skeleton unit integrates the inner and outer thermal break frames, utilizing its own structural strength and providing structural support for the first thermal insulation strip, thus giving the sealing support unit structural strength. This increases the thermal insulation capacity of the sealing support unit. With the bridge spacing in place, the overall support strength can be guaranteed, and the open groove formed by the skeleton body is used to fill the second aerogel felt. The first aerogel felt is set on the outside of the skeleton body, which can form a sandwich-type and grid-type aerogel felt layer at the partition, which can fully realize the thermal insulation at the bridge. In addition, a pressure sealing unit is set between the sub-frame and the fan frame. The pressure sealing unit is formed by the cooperation of the first step protrusion and the second step protrusion to form a step-type pressure seal. The second step protrusion can realize elastic deformation under pressure, which can fully seal the first step protrusion and the second step protrusion. At the same time, it can make the fan frame press and seal with other sealing parts of the sub-frame.

[0006] Furthermore, the skeleton is made of glass fiber reinforced PA66 GF30, and the first heat insulation strip, the upper heat insulation strip, the lower heat insulation strip, and the first stepped protrusion are all made of PA66 GF20; the isolation sealing strip is made of EPDM rubber; the skeleton has high structural strength, which can increase the structural strength of the main frame and the secondary frame at the broken bridge. The skeleton and the two first heat insulation strips can ensure the structural strength of the broken bridge position while increasing the width of the broken bridge position.

[0007] Furthermore, a first lower edge is integrally formed on the outer bottom of the sash frame, and an outer sealing strip is fitted on the inner side of the bottom of the first lower edge. A second lower edge is integrally formed on the inner bottom of the sash frame, and an inner sealing strip is pressed onto the inner side of the second lower edge. The inner sealing strip is engaged with the inner side of the sub-frame body, and the inner sealing strip is integrally formed with the isolation sealing strip. The bottom of the sash frame is provided with a first lower edge and a second lower edge. An outer sealing strip is installed at the bottom of the first lower edge. By pressing the outer sealing strip against the sub-frame body, the outer sealing strip actively deforms to achieve an active first seal. By pressing the second lower edge against the inner sealing strip, the inner sealing strip passively deforms to achieve a passive second seal. Through the cooperation of the active and passive sealing of the sealing strip, the window frame and sash frame can be fully sealed.

[0008] Furthermore, the outer surface of the sub-frame is integrally formed with a groove; the inner sealing strip is pressed against the inner side of the groove; the groove and the inner sealing strip of the sub-frame are sealed by an interlocking method, which can increase the sealing effect of the sub-frame and the fan frame.

[0009] Furthermore, multiple partitions are integrally formed between the upper and lower heat insulation strips. These partitions can create multiple compartments between the upper and lower heat insulation strips, thereby increasing the thermal insulation effect, the structural strength between the upper and lower heat insulation strips, and the structural strength at the broken bridge of the fan frame.

[0010] Compared with existing technologies, the high-performance energy-saving system window of this utility model, through the structural strength of the sealing support unit itself, can increase the spacing between the inner and outer thermal break frames while ensuring the structural strength of the entire window frame, thereby increasing the internal and external isolation effect. In addition, the sealing support unit itself has excellent thermal blocking performance, making the system window have better energy-saving effect.

[0011] The sash frame achieves two seals by pressing the outer sealing strip against the first lower edge and the second lower edge against the inner sealing strip. It also achieves multiple seals by cooperating with the first and second stepped protrusions. The second stepped protrusion is made of soft EPDM rubber, which can fully seal with the first stepped protrusion through deformation and can also fully press and seal the other two seals of the sash frame. This ensures that the sash frame and window frame are fully sealed, guaranteeing sufficient isolation between the inside and outside, and giving the system window better energy-saving performance.

The main frame 1, sub-frame 2, and sash frame 3 each include an inner thermal break frame 5 and an outer thermal break frame 6. A sealing support unit is provided between the inner thermal break frame 5 and the outer thermal break frame 6. A pressure sealing unit is provided between the sash frame 3 and the sub-frame 2. The sealing support unit includes: The skeleton body 7 has a square wave structure in its transverse cross-section.

[0019] The main frame 1 is assembled with the wall as a whole. The main frame 1 supports the secondary frame 2, and the secondary frame 2 supports the sash frame 3. Simultaneously, it cooperates with the sash frame 3 to achieve a seal between the sash frame 3 and the secondary frame 2. The sash frame 3 is used to install the vacuum glass 4, which provides thermal insulation between the inside and outside. The sealing support unit is installed between the inner thermal break frame 5 and the outer thermal break frame 6, providing support for both and achieving thermal insulation between the inside and outside. Specifically, the inner thermal break frame 5 and the outer thermal break frame 6 are integrated through the skeleton 7. The skeleton 7's structural strength is utilized, and it provides structural support for the first thermal insulation strip 12, giving the sealing support unit structural strength. This allows for increased thermal insulation... With a large thermal break spacing, the overall support strength can be guaranteed. The open groove formed by the skeleton body 7 is used to fill the second aerogel felt 10, and the first aerogel felt 9 is set on the outside of the skeleton body 7. This can form a sandwich-type and grid-type aerogel felt layer at the partition, which can fully realize the thermal insulation at the thermal break. In addition, a pressure sealing unit is set between the sub-frame 2 and the fan frame 3. The pressure sealing unit is formed by the cooperation of the first stepped protrusion 16 and the second stepped protrusion 17 to form a stepped pressure seal. The second stepped protrusion 17 can realize elastic deformation under pressure, which can fully seal the first stepped protrusion 16 and the second stepped protrusion 17. At the same time, it can make the fan frame 3 press and seal with other sealing parts of the sub-frame 2.

[0020] The skeleton body 7 is made of glass fiber reinforced PA66 GF30, and the first heat insulation strip 12, the upper heat insulation strip 13, the lower heat insulation strip 14 and the first stepped protrusion 16 are all made of PA66 GF20; the isolation sealing strip 15 is made of EPDM rubber; the skeleton body 7 has high structural strength and can increase the structural strength of the main frame 1 and the secondary frame 2 at the broken bridge. The skeleton body 7 and the two first heat insulation strips 12 can ensure the structural strength of the broken bridge position while increasing the width of the broken bridge position.

[0021] The bottom outer side of the sash frame 3 is integrally formed with a first lower edge 18, and an outer sealing strip 19 is fitted on the inner side of the bottom of the first lower edge 18. The bottom inner side of the sash frame 3 is integrally formed with a second lower edge 20, and an inner sealing strip 21 is pressed onto the inner side of the second lower edge 20. The inner sealing strip 21 is engaged with the inner side of the sub-frame 2 and is integrally formed with the isolation sealing strip 15. The bottom of the sash frame 3 is provided with a first lower edge 18 and a second lower edge 20. The outer sealing strip 19 is installed at the bottom of the first lower edge 18. By pressing the outer sealing strip 19 onto the sub-frame 2, the outer sealing strip 19 actively deforms to achieve an active first seal. By pressing the second lower edge 20 onto the inner sealing strip 21, the inner sealing strip 21 passively deforms to achieve a passive second seal. Through the cooperation of the active and passive sealing of the sealing strips, the window frame and sash frame 3 can be fully sealed.

[0022] The outer surface of the sub-frame 2 is integrally formed with a groove 22; the inner sealing strip 21 is pressed into the inner side of the groove 22; the groove 22 and the inner sealing strip 21 of the sub-frame 2 are sealed by an interlocking method, which can increase the sealing effect of the sub-frame 2 and the fan frame 3.

[0023] The upper heat insulation strip 13 and the lower heat insulation strip 14 are integrally formed with multiple partitions. The partitions can form multiple compartments between the upper heat insulation strip 13 and the lower heat insulation strip 14, thereby increasing the thermal insulation effect, increasing the structural strength between the upper heat insulation strip 13 and the lower heat insulation strip 14, and increasing the structural strength at the broken bridge of the fan frame 3.

[0024] This utility model discloses a high-performance energy-saving window system. The sealing support unit adopts a combination structure of skeleton body 7 and aerogel felt. The skeleton body 7 with a square wave structure provides structural support. At the same time, the multi-layer sandwich and grid layout of the aerogel felt achieve sufficient thermal insulation at the thermal break. While increasing the spacing between thermal breaks, it ensures the overall structural strength and improves the stability and durability of the window. Through multi-layer and multi-path thermal barrier design, the thermal bridge effect is significantly reduced, improving the energy-saving performance of the window. The pressure sealing unit forms a stepped pressure seal through the cooperation of the first stepped protrusion 16 and the second stepped protrusion 17. Utilizing the elastic deformation characteristics of EPDM rubber, it achieves full pressure sealing of multiple seals, realizing all-round sealing and improving the window's waterproof, dustproof and sound insulation performance.
