Description

Technical Field

[0001] The utility model relates to the technical field of door and window structures, in particular to a high-performance energy-saving casement window. Background Art

[0002] With the development of urban environment and the diversification of building structures, the noise, dust, external temperature and other factors in the environment have a greater impact on the internal environment of buildings. Windows are an important medium connecting indoor and outdoor. They are the direct structure to maintain a suitable indoor temperature and block external noise and dust. Therefore, there are higher requirements for the thermal insulation, sound insulation and sealing performance of windows. With the improvement of aesthetic needs, people's demands for the internal and external visual effects of windows are also getting higher and higher.

[0003] Many current window structures, especially casement window structures, ensure sealing performance by installing sealing strips on the window sash structure to isolate external dust and rainwater, and improve thermal insulation by increasing the thickness of the glass window sash. To prevent rainwater from entering the room, multiple drainage holes are provided on the window frame to drain rainwater from the window frame, especially some drainage holes are provided on the horizontal center stile to drain rainwater from the upper part of the window. However, in actual use, the drainage holes on the center stile will damage the external structure of the horizontal center stile, resulting in reduced airtightness inside and outside the window. Even if a drainage cover or windproof cap is installed, it cannot prevent indoor heat loss, which is not conducive to maintaining indoor temperature and has a poor energy-saving effect. At the same time, the drainage holes on the horizontal center stile are difficult to align with the drainage holes on the lower part of the window frame. It takes a lot of effort and cost to align the drainage hole structure, otherwise it will affect the aesthetics of the window and increase the cost of the window.

[0004] It can be seen that the current casement window structure still has room for improvement. It should be optimized and improved to improve the energy-saving effect of the casement window structure, improve the aesthetics of the casement window structure, and reduce the cost of the casement window structure. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above, the utility model proposes a high-performance energy-saving casement window. By improving the overall structure of the window sash, the thermal insulation performance of the window is guaranteed, the drainage requirements can be met, and the beauty of the window is maintained.

[0006] In order to achieve the above-mentioned purpose, the casement window disclosed in the present utility model can adopt the following technical solutions:

[0007] A high-performance energy-saving casement window comprises a fixed window frame and a casement window frame matched therewith, wherein the upper side frame of the casement window frame matches the horizontal stile of the fixed window frame, and the horizontal stile is provided with a plurality of drainers, the upper ends of the drainers being connected to the glass sash water collection grooves of the horizontal stile, and the lower ends of the drainers forming a horizontal drainage outlet flush with the outer surface of the horizontal stile; at least two layers of sealing strips are provided between the casement window frame and the fixed window frame and the horizontal stile to form a double-layer seal.

[0008] The above-mentioned casement window improves the drainage structure at the horizontal center mullion, thereby ensuring the sealing of the casement window, reducing the loss of indoor heat, and maintaining the airtightness of the window. At the same time, it can also meet the drainage performance of the horizontal center mullion. The appearance of the window sash is not damaged by the drainage structure, and the overall aesthetics are good.

[0009] Furthermore, the drainer is used to guide the water in the sump downward and ultimately drain it outward. This can be achieved using a variety of solutions, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the drainer includes a vertically arranged drain pipe body, which is equipped with a water-permeable and windproof foam. When using this solution, the drainer directly forms a drainage channel and can be adapted to the structure of the horizontal center mullion to guide water to a preferred location for discharge, thereby not affecting the external aesthetics of the window.

[0010] Furthermore, to maintain the window's tightness, the double-layer seal formed by the sealing strip can maintain sufficient tightness. The sealing strip can be disposed in a variety of ways, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: an inner sealing strip is disposed on the inner side of the casement window frame, or the inner side of the fixed window frame and the horizontal muntin. When the casement window frame deflects and mates with the fixed window frame and the horizontal muntin, the inner sealing strip seals the mate surface. When this solution is adopted, a sealed cavity is formed within the inner sealing strip, and the casement window frame, the fixed window frame, and the horizontal muntin compress the inner sealing strip to form a sealed structure.

[0011] Furthermore, another purpose of providing a sealing strip to maintain sealing can be achieved through other means, and the structure is not limited to a single one. Here, we optimize and propose one feasible option: the outer peripheral surface of the casement window frame is provided with a peripheral sealing strip, and the side surfaces of the fixed window frame, the horizontal center mullion and the casement window frame corresponding to each other are provided with an isobaric sealing strip. When the casement window frame deflects and aligns with the fixed window frame and the horizontal center mullion, the peripheral sealing strip and the isobaric sealing strip align to form a seal. When adopting this solution, the peripheral sealing strip cooperates with the isobaric sealing strip at a certain angle to achieve sealing.

[0012] Furthermore, casement window frames can adopt a variety of frame structures. To achieve better thermal insulation performance, their structures are not limited to a single one. Here, we optimize and propose one feasible option: the casement window frame includes an outer frame and an inner frame, with a gap formed between the outer and inner frames, and a plurality of thermal insulators disposed longitudinally within the gap. The peripheral sealing strip is integrally formed with the outermost thermal insulator. When adopting this solution, the formation of multiple cavities within the thermal insulator improves thermal insulation, thereby achieving the purpose of thermal insulation. Furthermore, the provision of multiple layers of thermal insulators can further enhance the thermal insulation effect.

[0013] Furthermore, when the glass sash is connected and set through the casement window frame, it can be installed through a variety of structures, and its structure is not limited to a single one. Here, optimization is made and one of the feasible options is proposed: the inner frame is an integral structure and forms an inner stop for pressing against the glass sash, the outer frame includes a base frame and a fastening frame that are connected and matched, the heat insulation body is located between the base frame seat and the inner frame, and the fastening frame forms an outer stop and forms a clamping structure corresponding to the inner stop. When the above scheme is adopted, the inner stop is integrally formed with the inner frame, the collective frame seat and the fastening frame are detachably connected, and can be connected and fixed by snap fastening, or connected and fixed by fasteners. Glass sash sealing strips are provided at both the inner stop and the outer stop to achieve connection and sealing.

[0014] Furthermore, the fixed window frame structure can adopt a variety of solutions. It needs to connect to the glass sash and cooperate with the casement window frame at the same time. Its structure is not limited to a single one. Here, we optimize and propose one feasible option: the fixed window frame includes an outer fixed frame body and an inner fixed frame body. The outer and inner fixed frames form a gap, and a plurality of thermal insulation bodies are longitudinally arranged in the gap. When adopting this solution, a plurality of cavities are also formed in the thermal insulation body of the fixed window frame to improve thermal insulation.

[0015] Furthermore, while ensuring waterproofing, external water enters the fixed frame and is discharged outward through the frame. Drainage can be achieved through a variety of solutions, and the structure is not limited to a single one. Here, we optimize and propose one feasible option: the external fixed frame is formed with a frame volume water trough, which is formed with a plurality of drain ports, and the drain ports are provided with drain covers. When using this solution, water in the frame volume water trough flows outward through the drain ports, and the drain covers can improve airtightness to a certain extent and reduce indoor temperature loss. The drain ports and drain covers are located at the bottom of the external fixed frame, so they will not adversely affect the appearance of the window.

[0016] Furthermore, in some solutions, it is necessary to open the casement window while also ensuring isolation of large particles. Therefore, the window structure can be optimized. This structure is not strictly limited. Here, we propose one possible option: the external fixed frame is connected to a detachable screen sash, one side of the screen sash is hinged to the external fixed frame, and the other side is engaged with the external fixed frame via a screen lock. When adopting this solution, the screen sash can also be set as a casement structure, which can be locked by the screen lock.

[0017] Furthermore, the structure of the horizontal muntin can adopt a variety of schemes, the purpose of which is to improve its thermal insulation performance. Its structure is not limited to a single one. Here, we optimize and propose one feasible option: the horizontal muntin includes an outer muntin body and an inner muntin body. A gap is formed between the outer muntin body and the inner muntin body, and a plurality of thermal insulators are longitudinally arranged in the gap. The uppermost thermal insulator is used to cooperate with and support the glass sash above. The outer fixed frame and the outer muntin body are formed with outer ribs for abutting the glass sash. The inner fixed frame and the inner muntin body are both connected to a closed pressure strip that abuts the glass sash and form a clamping structure corresponding to the outer ribs. When adopting the above scheme, a plurality of cavities can be set in the thermal insulation body to improve the thermal insulation effect, and both the inner ribs and the outer ribs can be provided with glass sash sealing structures.

[0018] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0019] The utility model improves the drainage structure of the casement window, improves the sealing performance, reduces the convection of indoor and outdoor temperatures, and thus saves indoor energy; at the same time, the two-layer sealing structure adopted can improve the waterproof performance and sound insulation effect, and improve the comfort of the indoor environment.
