[0002] In today's construction industry, where energy conservation, environmental protection, aesthetics, and comfort are constantly being pursued, the performance of doors and windows, as an important component of building envelopes, is receiving considerable attention. Aluminum alloy clad wood windows combine the natural beauty of wood with the sturdiness and durability of aluminum alloy, making them a popular window choice in the market.

[0003] However, traditional aluminum alloy clad wood windows have several shortcomings in their sealing design. In terms of sealing performance, traditional aluminum alloy clad wood windows typically employ a double or triple sealing structure, which is insufficient to effectively resist wind and rain. Under inclement weather conditions, rainwater can easily seep into the room, affecting the dryness and comfort of the indoor environment. Simultaneously, poor sealing leads to frequent air exchange between indoors and outdoors, reducing the window's thermal insulation effect and increasing building energy consumption. Regarding the design of the window frame and sash, traditional aluminum alloy clad wood windows are relatively thick and heavy to ensure structural strength and stability. This not only increases construction costs but also limits the window's light-gathering area. With people's increasing demands for lighting and views in their living spaces, this design of traditional aluminum alloy clad wood windows can no longer meet market needs. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides an aluminum alloy-clad wood window. The technical solution adopted by this utility model is as follows:

[0005] An aluminum alloy clad wood window includes a window frame and a window sash rotatably connected to the window frame. The window frame includes an inner wood window frame and an outer aluminum alloy window frame fixedly assembled as one piece. The window sash includes an inner wood window sash and an outer aluminum alloy window sash fixedly assembled as one piece. A first sealing strip is installed on the outer aluminum alloy window frame, a second sealing strip is installed on the inner wood window frame, and a third and fourth sealing strip are both installed on the inner wood window sash. The first and third sealing strips adopt a soft and hard co-extruded structure.

Detailed Implementation

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] like Figures 1-8 As shown, an aluminum alloy clad wood window includes a window frame 1 and a window sash 2. The right side frame of the window sash 2 is connected to the window frame 1 via a hinge 5 for opening and closing. A glass pane 3 is inlaid in the center of the window sash 2. A window lock handle 4 is installed in the center of the window sash 2 frame away from the hinge 5. A window lock actuator 6 is fixedly connected to the inner end of the window lock handle 4. By driving the window lock actuator 6 through the window lock handle 4, the opening or locking of the left side frame and the top and bottom frames of the window sash 2 with the window frame 1 can be achieved. The hinge 5 can be a surface-mounted hinge or a concealed hinge. Figure 1 and Figure 2 Hinge 5 in the picture is a surface-mounted hinge. Figure 8 Hinge 5 is a concealed hinge. Window frame 1 and window sash 2 can adopt a slim design, reducing the width of window frame 1 and window sash 2 while ensuring strength and stability, thereby improving aesthetics and the openness of the view, and meeting the aesthetic and functional requirements of modern architecture for doors and windows.

[0029] The window frame 1 is a rectangular frame structure, including an inner wooden window frame and an outer aluminum alloy window frame. The outer aluminum alloy window frame is installed on the side of the inner wooden window frame facing the outside through several first frame rotating clips 1-5. By adjusting the position of the first frame rotating clips 1-5, the overall size of the window frame 1 meets the installation requirements, forming a stable frame structure. The outer aluminum alloy window frame is a rectangular frame structure consisting of aluminum alloy profiles 1-7 for the upper frame, 1-3 for the lower frame, and 1-2 for the side frames, which are fixedly connected or welded together using corner brackets. The use of corner brackets ensures the structural strength of the outer aluminum alloy window frame. If corner brackets are used, matching corner brackets and screws are required to fix the aluminum alloy profiles together. If welding is used, the welding quality must be ensured. The inner wood window frame is a rectangular frame structure consisting of wood profiles 1-8 for the upper frame, 1-9 for the lower frame, and 1-1 for the side frames, which are joined together using mortise and tenon joints. The mortise and tenon joints ensure the structural strength of the inner wood window frame, while also showcasing the natural beauty of the wood. An aluminum alloy drip edge 1-4, sloping downwards and outwards, is fixed to the exterior-facing side of the lower frame wood profile 1-9 of the window frame using several screws. A drainage hole 13 is located at the lower part of the aluminum alloy profile 1-3 of the lower frame above the drip edge 1-4, allowing rainwater that may flow onto the surface of the lower frame wood profile 1-9 to drain smoothly. Both the drainage hole 13 and the design of the aluminum alloy drip edge 1-4 are existing technologies. Thermal insulation profiles 1-6 are fixed to the exterior-facing sides of the upper frame wood profile 1-8 and the side frame wood profiles 1-1 on both sides of the window frame. The thermal insulation profile 1-6 is located between the inner wooden window frame and the outer aluminum alloy window frame. It can be glued and fixed to the exterior-facing side of the inner wooden window frame. By installing the thermal insulation profile 1-6, heat transfer is effectively blocked, reducing the window's heat transfer coefficient, minimizing indoor heat loss in winter and outdoor heat entry in summer, thus reducing building energy consumption and achieving the goal of energy conservation and environmental protection.

[0030] The window sash 2 is a rectangular frame structure that matches the dimensions of the window frame 1. It includes an inner wooden window sash and an outer aluminum alloy window sash. The outer aluminum alloy window sash is installed on the exterior-facing side of the inner wooden window sash via several second frame rotating clips 2-3, ensuring the splicing accuracy and strength of the window sash 2. The outer aluminum alloy window sash is a rectangular frame structure consisting of an upper frame aluminum alloy profile 2-2, a lower frame aluminum alloy profile 2-7, and two side frame aluminum alloy profiles 2-5, fixedly connected or welded together using corner brackets. The inner wooden window sash is a rectangular frame structure consisting of an upper frame wooden profile 2-1, a lower frame wooden profile 2-8, and two side frame wooden profiles 2-6, spliced ​​together using mortise and tenon joints. The inner wooden window sash and the outer aluminum alloy window sash together form a rectangular frame groove for installing the glass 3. The gaps in the rectangular frame groove for installing the glass 3 are filled with expanding foam 2-4.

[0031] Four sealing strips are installed at the overlap between window frame 1 and window sash 2 to achieve a good sealing effect for the aluminum alloy-clad wood window. Figure 4 and Figure 5 Taking the overlapping window frame side frame and window sash side frame as an example, a frame hardware mounting groove 14 is opened at the end of the window frame side frame wood profile 1-1 near the interior, and a second sealing strip mounting groove 15 is opened at the end of the window frame side frame wood profile 1-1 near the exterior. A second sealing strip mounting groove 16 is formed between the end of the window frame side frame wood profile 1-1 near the exterior and the end of the window frame side frame aluminum alloy profile 1-2. The two ends of the second sealing strip 8 are inserted into the second sealing strip mounting groove 15 and the second sealing strip mounting groove 16 respectively, thus achieving the fixed installation of the second sealing strip 8. A first sealing strip mounting groove 17 is provided at the end of the window frame side frame aluminum alloy profile 1-2 near the glass 3. The first sealing strip 7 with a soft and hard co-extruded structure is inserted into the first sealing strip mounting groove 17, thus achieving the fixed installation of the first sealing strip 7. A fourth sealing strip mounting groove 18 is opened at the end of the window sash side frame wood profile 2-6 adjacent to the window frame side frame wood profile 1-1 on the indoor side. The fourth sealing strip 10 is inserted into the fourth sealing strip mounting groove 18 to achieve the fixed installation of the fourth sealing strip 10. A third sealing strip mounting groove 20 is opened at the middle position of the window sash side frame wood profile 2-6 adjacent to the window frame side frame wood profile 1-1 on the outer side. The third sealing strip 9 with a soft and hard co-extruded structure is inserted into the third sealing strip mounting groove 20 to achieve the fixed installation of the third sealing strip 9. For installation, a sash hardware installation groove 19 is opened between the fourth sealing strip installation groove 18 and the third sealing strip installation groove 20; an inner glass sealing strip installation groove 20 is opened at the position of the wooden profile 2-6 of the window sash side frame adjacent to the glass 3, and the inner glass sealing strip 12 is inserted into the inner glass sealing strip installation groove 20 to achieve the fixed installation of the inner glass sealing strip 12; an outer glass sealing strip installation groove 22 is opened at the position of the aluminum alloy profile 2-5 of the window sash side frame adjacent to the glass 3, and the outer glass sealing strip 11 is inserted into the outer glass sealing strip installation groove 22 to achieve the fixed installation of the outer glass sealing strip 11.

[0032] The first sealing strip 7 includes a fixed clip and part 23 and a compression part 24, both of which are integrally structured. One end of the fixed clip and part 23 engages with the first sealing strip mounting groove 17, and the other end of the fixed clip and part 23 is connected to the compression part 24, which is configured as an n-shape. The third sealing strip 9 includes a fixed clip and part 25, a support part 27, and a compression part 26, both of which are integrally structured. The bottom of the compression part 26 is connected to the side of the support part 27, and the bottom of the support part 27 is connected to the top of the fixed clip and part 25. The fixed clip and part 25 is configured as an n-shape, and two protrusions are provided on the structural members of the fixed clip and part 25 that are inserted into the third sealing strip mounting groove 20 to make the installation of the third sealing strip 9 more secure. Both compression section 1 (24) and compression section 2 (26) are foamed to make them more elastic. Compared with traditional sealing strips, the first sealing strip 7 and the third sealing strip 9 have increased compression, which makes the sealing performance better after the window sash 2 is closed, enhancing the waterproof, heat insulation and sound insulation effects, and can better adapt to the slim design of aluminum alloy wood-clad windows.

[0033] The first sealing strip 7, the second sealing strip 8, the third sealing strip 9, and the fourth sealing strip 10 are all made of ethylene propylene diene monomer (EPDM) rubber, which has excellent weather resistance, aging resistance, and sealing performance. Even under long-term exposure to wind, sun, and rain, they maintain good elasticity and sealing properties, effectively preventing the penetration of rainwater, dust, and air, ensuring a long-lasting and stable window seal.

[0034] The first sealing strip 7 is installed on the outer aluminum alloy window frame, the second sealing strip 8 is installed on the inner wooden window frame, and the third sealing strip 9 and the fourth sealing strip 10 are both installed on the inner wooden window sash. When the window is closed, the outer side of the outer aluminum alloy window sash abuts against the compression part 24 of the first sealing strip 7, the outer side of the inner wooden window sash abuts against the second sealing strip 8, the side wall of the inner wooden window frame abuts against the compression part 26 of the third sealing strip 9, and the inner side of the inner wooden window frame abuts against the fourth sealing strip 10. Glass 3 is installed within the glass mounting groove of window sash 2, located between the outer aluminum alloy sash frame and the inner wooden window sash. An outer sealing strip 11 is installed on the outer aluminum alloy sash frame to mate with the exterior side of glass 3, while an inner sealing strip 12 is installed on the inner wooden window sash to mate with the interior side of glass 3. Expanding foam 2-4 is filled into the installation gap of glass 3. Once the outer aluminum alloy sash frame and the inner wooden window sash of window sash 2 are engaged using the second frame rotating clip 2-3, the installation of glass 3 is complete. During the installation of glass 3, it is crucial to ensure its correct position, preventing tilting or offset. Simultaneously, a tight seal must be maintained between the outer and inner sealing strips 11 and 12, and between glass 3 and window sash 2, to prevent air or water leakage.

[0035] The window sash 2 is rotatably connected to the window frame 1 via at least two hinges 5. Multiple screws are used to install the hinges 5 onto the wooden profiles 1-1 of the window frame side frame and 2-6 of the window sash side frame. During installation, it is necessary to ensure the accurate positioning of the hinges 5 so that the window sash 2 can open and close smoothly. If concealed hinges are used, they must be installed precisely according to the product instructions to ensure a tight fit between the concealed hinges and the window frame 1 and window sash 2, without affecting the overall aesthetics of the window.

[0036] When installing sealing strips, ensure their flatness and continuity to avoid twisting or breakage. During installation, the sealing strips must be securely fixed in their positions to ensure that four effective sealing lines are formed when the window is closed, preventing rainwater, dust, and air penetration.

[0037] When filling the insulation profiles 1-6, ensure they are securely installed and prevent loosening or detachment. When filling the expanding foam 2-4, follow the instructions carefully, controlling the amount and placement to ensure it fully fills the gaps in the glass 3. The insulation profiles 1-6 and expanding foam 2-4 effectively block heat transfer, improving the window's thermal insulation performance.

[0038] Hardware Installation: The hardware mainly consists of three parts: the operating component, the load-bearing component, and the transmission and opening / closing component. The operating component is the window lock handle 4, which controls the opening and closing of the window under external force. The window lock handle 4 is screwed onto the window sash 2, and machine screws are used to connect the window lock handle 4 to the window lock actuator 6. The load-bearing component is the hinge 5, which connects the window frame 1 and the window sash 2 and bears the window opening load. Multiple screws are used to install the hinge 5 on the side edges of the wooden profiles inside the frame and the sash. The transmission and opening / closing component is the window lock actuator 6, which transmits the operating force to open and close the window sash 2. Multiple screws are used to install the window lock actuator 6 on the inner wooden window frame and the inner wooden window sash. When installing the window lock handle 4, ensure that its installation position is convenient for user operation and that the connection with the window lock actuator 6 is firm and reliable, allowing for flexible control of the window's opening and closing function. By selecting different hardware systems, different opening functions such as inward-opening casement windows, inward-opening bottom-hung windows, and bottom-hung windows can be achieved to meet the usage needs and ventilation requirements of different users.

[0039] This utility model embodiment includes a four-layer sealing structure, comprising a first sealing strip 7, a second sealing strip 8, a third sealing strip 9, and a fourth sealing strip 10, along with multiple seals on the glass 3, effectively preventing the penetration of rainwater, dust, and air. In heavy rain, traditional aluminum alloy clad wood windows may experience rainwater leakage, while this utility model's four-layer sealing design effectively avoids such problems. In buildings with high lighting requirements, such as residences and office buildings, this utility model can provide a better lighting experience, making the interior brighter and more transparent. Taking winter heating as an example, using this utility model's aluminum alloy clad wood window can reduce heating energy consumption and lower heating costs.
