Description

Technical Field

[0001] This utility model relates to the field of building energy conservation technology, and in particular to a low-energy-consumption inward tilting and sliding door and window. Background Technology

[0002] Traditional sliding or casement windows have certain limitations in architectural applications. While sliding windows save space, they have poor sealing and wind pressure resistance, making them prone to water leakage and air leaks, especially in extreme weather conditions. Casement windows, on the other hand, have better sealing, but they require additional indoor or outdoor space when opened, affecting the use of curtains, balconies, and other facilities, and pose safety hazards in windy weather.

[0003] In recent years, tilt-and-turn windows have gradually gained market attention as a new type of window, combining the space-saving advantages of sliding windows with the airtightness of casement windows, making them popular with users. However, existing tilt-and-turn windows have shortcomings in their structural design, such as: 1. The upper and lower rails of the operable sash are sliding pulleys and cannot be fitted with locking points. When the width of the operable sash exceeds 1 meter, its sealing and sound insulation are significantly reduced, and it cannot achieve the excellent sealing performance of an inward-opening bottom-hung window (inward-opening tilt-and-turn window).

[0004] 2. Single thermal break structure, with a total window insulation K-value of 2.0~2.5W / (m²). 2 Between ·k), according to national energy conservation requirements, the energy conservation standard for new buildings in 2025 will be 30% higher than that in 2020, and the heat transfer coefficient (K value) of doors and windows will be required to be ≤1.5 (≤1.2 in extremely cold regions). It can be seen that the existing tilt-and-turn windows will face the risk of being phased out.

[0005] Therefore, it is essential to provide a low-energy-consumption tilt-and-turn window structure to address the issues of high thermal insulation K-value leading to obsolescence, the inability of the sealing and sound insulation performance in the locked state to match the superior performance of inward-opening tilt-and-turn windows, and to promote the transformation and upgrading of doors and windows towards green, low-carbon, energy-saving and environmentally friendly directions, thus contributing to the high-quality development of the industry.

[0012] The inner end of the horizontal stile is provided with a slot for mounting the track, and the outer end is provided with a drain cover for a movable air damper.

[0013] The vertical mullion has a double-broken bridge structure, and both broken bridge structures are filled with thermal insulation filler.

The cover profile is used to cover the ninth-type C-shaped slot. The shaped sealing strip is located at the end away from the connection between the pressure line profile and the dummy fan profile.

[0016] The present invention has the following beneficial effects by adopting the above technical solution: (1) The present invention adopts a double thermal break structure for the horizontal window frame, vertical window frame, horizontal mullion, vertical mullion and glass sash, and fills the thermal break mechanism with heat insulation filler to form multiple thermal resistance barriers. Combined with the aluminum-plastic co-extruded heat insulation layer on the inner wall of the profile, it can effectively block the heat conduction path, so that the door and window profile has good heat insulation and heat insulation properties. The double thermal break structure can significantly improve the heat insulation and sound insulation performance of the door and window.

[0017] (2) The present invention prepares the outdoor profile as a heat-insulating aluminum-plastic co-extruded profile, and its heat-insulating micro-foamed layer is co-extruded on the inner wall of the aluminum profile and filled with heat-insulating and sound-insulating materials in the first and second heat-insulating cavities. This can significantly reduce the K value of the entire door and window and improve the heat insulation performance. It can also solve the problems of the plastic layer being exposed to the outdoors for a long time, becoming brittle, and fading easily, and extend the service life of the entire window. (3) The corner bracket part of the assembly in this utility model is intentionally not designed with plastic co-extruded layer, so that the processing and assembly process of aluminum-plastic co-extruded profile is exactly the same as the existing process of thermally broken aluminum such as corner, pin or movable corner bracket, etc. Door and window companies do not need to purchase plastic steel door and window welding equipment, which is conducive to the promotion and application of this utility model; (4) This utility model constructs several C-shaped slots; by installing different locking points and hardware in different C-shaped slots, two opening and closing methods can be provided for selection. One is the lock box type, in which the locking points are designed in the C-shaped slots of the movable sash. The locking points are distributed on the upper and lower parts of the left and right sides of the movable sash. The number of locking points is generally not less than 4. The top and bottom of the movable sash are vertical sliding wheels. The opening and closing of the window is realized by the torsion belt transmission rod of the lock box, the corner device and the engagement between the locking points and the locking hook, and the tilting function is realized by the deflector. It is mainly used for windows with movable sashes less than 1 meter in length. The other is the fork type, in which the transmission hardware and locking points are set in the movable sash. In the other C-shaped slot, locking points are distributed in the four directions of the movable sash: up, down, left, and right. The number of locking points can be increased arbitrarily according to the width and height of the opening sash. The position of the up and down sliding wheels of the movable sash is the same as that of the lock box type opening and closing. The opening and closing of the window is realized by the engagement between the fork, the drive rod, the corner device, and the locking points and the lock hook. The tilting function is realized by the deflector in the C-shaped slot. It is mainly used for windows with movable sashes larger than 1 meter. The increase of locking points can meet the personalized selection needs of users with extra-large opening ventilation area. It can also make the door and window achieve the same performance effect of air tightness, water tightness and sound insulation as the inward opening and tilting door and window structure. (5) The profile of this utility model has an extremely low heat transfer coefficient, which can block the heat from the outside as much as possible at the outermost or innermost edge of the effective sealing structure of the window. It corrects the shortcomings of the single-bridge structure and the fact that the heat insulation cavity is set in the middle of the window in the background technology, which affects the heat insulation performance. According to the size of the movable sash, the lock box type or the fork type multi-locking point scheme can be selected to meet personalized needs and reduce costs. It can significantly improve the sealing performance of the window, prevent the external cold and heat effects from seeping in or dissipating through the window, reduce the exchange of heat between indoor and outdoor, reduce heating and cooling energy consumption, avoid heat loss caused by cold and heat transfer, and help maintain a stable indoor temperature. When this utility model is matched with 10.3V+16A+6Lov-e titanium metal vacuum glass or triple-glazed double-cavity Lov-e glass, its overall window K value is ≤0.8W / (m 2 ·k) is an ideal product for green building ultra-low energy consumption doors and windows and passive house doors and windows.
