Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy window technology, specifically a heat-insulating aluminum alloy window. Background Technology

[0002] Modern windows mainly consist of three parts: the window frame, the glass, and the moving parts. The window frame, as the main structure supporting the window, can be made of various materials such as wood, metal, ceramic, or plastic; the transparent part is attached to the window frame, and common materials include paper, cloth, silk, and glass; the moving parts are mainly made of metal, and the parts that come into contact with people are often covered with heat-insulating materials such as plastic to improve the user experience.

[0003] Traditional windows often use double-glazed windows for insulation, but aluminum alloy window frames have a high thermal conductivity, allowing heat to easily conduct through the frame and resulting in poor indoor insulation. To solve this problem, thermally broken aluminum alloy windows have gradually been applied to window frames. The insulation principle of thermally broken aluminum alloy windows is to use a plastic with low thermal conductivity to separate the inner and outer aluminum alloy frames, preventing them from contacting each other and effectively improving thermal insulation performance. Compared to traditional aluminum alloy windows, the insulation effect is significantly enhanced.

[0004] However, the thermal insulation performance of glass still falls short of people's growing needs. In summer, the sun is intense, and a large amount of heat enters the room through radiation. Traditional double-glazed windows can only block heat conducted through heat. If glass that blocks radiation were used, in winter, the heat radiation from the sun would be difficult to enter the room, leading to insufficient natural light and wasted energy resources. Furthermore, privacy cannot be simultaneously guaranteed, making the function of windows relatively limited. Utility Model Content

[0005] To address the problem that existing windows offer limited insulation and cannot meet diverse insulation needs, this invention provides a heat-insulating aluminum alloy window.

[0006] This utility model is achieved through the following technical solution: a heat-insulating aluminum alloy window, including a thermally broken aluminum frame and two panes of glass disposed within the thermally broken aluminum frame, with a gap between the two panes of glass. Heat-insulating mechanisms are connected and installed in the cavities of the vertical portions on both sides of the thermally broken aluminum frame. Each heat-insulating mechanism includes a first motor connected and installed to the top inner side of the thermally broken aluminum frame. A vertical protective cylinder is connected and installed on the outer side of the first motor housing. A rectangular opening is provided on the side of the protective cylinder near the glass. The lower end of the protective cylinder is connected and installed to the bottom side of the thermally broken aluminum frame. A bearing is connected and installed inside the bottom side of the protective cylinder. A rotating rod is connected and installed on the inner ring of the bearing. The top end of the rotating rod is connected to the output shaft of the first motor. A heat-insulating film, located within the gap between the two panes of glass and passing through the rectangular opening, is wound together on the rotating rods of both heat-insulating mechanisms. The heat-insulating film includes several film bodies connected in sequence.

[0007] A further improvement of this utility model is that an exhaust mechanism is connected and installed in the horizontal cavity on both the upper and lower sides of the thermally broken aluminum frame. The exhaust mechanism includes a support frame, with several first through holes on one side and a protrusion on the top. Several vertical second through holes are located on the protrusion, which is connected to glass on both sides. Two support plates are connected and installed inside the support frame, with an impeller rotatably connected between them. A second motor is connected and installed on the side of the support plate away from the impeller, and the output shaft of the second motor is connected to the impeller. A shunting cover, partially enclosing the impeller, is also connected and installed between the two support plates. The air outlet of the shunting cover of the bottom exhaust mechanism is aligned with the second through holes, and the air outlet of the shunting cover of the top exhaust mechanism is aligned with the first through holes. A third through hole, coaxial with the first through hole, is located on the outdoor side of the top of the thermally broken aluminum frame, and a third through hole, coaxial with the first through hole, is located on the indoor side of the bottom of the thermally broken aluminum frame. In severe weather conditions such as continuous rain or sandstorms, where opening windows for ventilation is not advisable, traditional window ventilation methods are insufficient to meet indoor air quality requirements. At this time, the exhaust system actively draws indoor air out through the fan, creating a negative pressure environment indoors. Based on the principle of atmospheric pressure, fresh outdoor air automatically flows into the room through gaps in doors and windows, fresh air ducts, and other channels, thus achieving the goal of efficient air circulation. This ventilation method not only effectively reduces indoor carbon dioxide concentration and residual odors from renovations, but also precisely solves the problem of fogging between glass panes. Through continuous airflow, it quickly removes humid air between the glass layers, effectively inhibiting fog formation and keeping windows clear and bright, ensuring good indoor lighting and creating a healthy and comfortable indoor environment.

[0008] A further improvement of this invention is that both panes of glass are double-layered argon-filled glass. This effectively blocks heat transfer, improves the window's insulation performance, and saves energy.

[0009] A further improvement of this invention is that a curved polytetrafluoroethylene (PTFE) lubricating pad is provided at the inner corner of the two vertical sections of the glass. PTFE is self-lubricating, providing lubrication during the sliding of the heat insulation film, reducing friction, preventing damage to the heat insulation film, and the curved surface guides the heat insulation film, further reducing friction and ensuring that the heat insulation film remains in the middle of the glass gap, preventing it from adhering to the glass.

[0010] A further improvement of this invention is that a polytetrafluoroethylene (PTFE) lubricating block is provided around the rectangular opening. PTFE is self-lubricating, providing lubrication during the sliding of the heat insulation film, reducing friction, and preventing damage to the heat insulation film.

[0011] A further improvement of this invention is that the first motor is a miniature servo motor. This enables the rotating rods on both sides of the heat insulation film to rotate synchronously, keeping the heat insulation film taut and preventing wrinkles from affecting its appearance.

[0012] A further improvement of this invention is that the heat-insulating film is composed of several film layers sequentially spliced ​​together, including a light-blocking film, a heat-insulating transparent film, a frosted film, and a transparent film. By switching between different film layers, it can provide different lighting scenarios and privacy protection, thus meeting people's needs under different environmental conditions.

[0013] A further improvement of this invention is that a heat-insulating strip is filled between the inner side of the cavity of the thermally broken aluminum frame and the protective cylinder. This further enhances the heat insulation effect and prevents heat from being conducted through the aluminum alloy, which would affect the heat preservation effect and cause resource waste.

[0014] A further improvement of this invention is that each of the third through holes is equipped with a one-way valve. This ensures that air can only be conducted from indoors to outdoors, preventing outside air from entering the room and affecting the heat insulation effect when the exhaust mechanism is not working.

[0015] A further improvement of this invention is that the support frame is a PA66 nylon strip. PA66 nylon strips possess excellent supporting toughness and thermal insulation properties, enabling them to provide stable support for the glass while improving thermal insulation performance.

[0016] As can be seen from the above technical solution, the beneficial effects of this utility model are: by synchronously rotating the first motors on both sides, the rotating rod is driven to rotate, causing the heat insulation film wound on the rotating rod to rotate, thereby allowing the heat insulation film between the two glass panes to alternately replace different types of heat insulation film, which can adapt to different scenarios. For example, during the day, light needs to be transmitted, and at night, light needs to be blocked to effectively protect privacy. In winter, light needs to be able to fully enter the room to increase the indoor temperature, while in summer, most of the light needs to be blocked to reduce the heat radiation entering the room. This intelligent switching mechanism breaks through the functional limitations of traditional fixed heat insulation film. Through the combination and dynamic switching of heat insulation films of different materials, while meeting the building energy-saving requirements, it provides users with a full-scenario solution that takes into account lighting, heat insulation, and privacy protection.

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] As shown in the figure, this utility model discloses a thermally insulated aluminum alloy window, including a thermally broken aluminum frame 1, two glass panes 2 disposed within the thermally broken aluminum frame 1, with a gap between the two glass panes 2 and a thermal insulation mechanism 3 connected and installed in the vertical cavities on the left and right sides of the thermally broken aluminum frame 1. The thermal insulation mechanism 3 includes a first motor 32 connected to the inner top of the thermally broken aluminum frame 1 by a self-drilling screw 31. An upright protective cylinder 33 is interference-fitted to the outer side of the housing of the first motor 32. The protective cylinder 33 has a rectangular opening 37 on the side near the glass panes 2. The end is connected to the bottom side of the cavity of the thermally broken aluminum frame 1. The bearing 34 is connected and installed inside the bottom side of the protective cylinder 33. The inner ring of the bearing 34 is connected and installed with the rotating rod 35. The top of the rotating rod 35 is connected to the output shaft of the first motor 32. The rotating rods 35 of the two heat insulation mechanisms 3 are wound together with a heat insulation film 36 that is located in the gap between the two glass 2 and passes through the rectangular opening 37. The heat insulation film 36 is composed of four types of film bodies spliced ​​together in sequence. The size of the heat insulation film 36 between the two glass 2 is just enough to cover the window glass. The two ends of the heat insulation film 36 are neatly glued to the rotating rod 35.

[0028] In use, the first motor 32 is started, driving the rotating rod 35 to rotate, causing the heat insulation film 36 wound on the rotating rod 35 to rotate. The heat insulation film 36 on one side of the rotating rod 35 rotates out from the rectangular opening 37, passes through the gap between the two glass panes 2, and rotates into the rotating rod 35 on the other side. This allows the heat insulation film 36 between the two glass panes 2 to alternately change to different types of film, which can adapt to different scenarios. For example, it needs to allow light to pass through during the day and block light at night to effectively protect privacy. In winter, it needs to allow enough light to enter the room to increase the indoor temperature, while in summer, it needs to block most of the light to reduce the heat radiation entering the room. This intelligent switching mechanism breaks through the functional limitations of traditional fixed heat insulation films. Through the combination and dynamic switching of film with different material effects, it provides users with a full-scenario solution that takes into account lighting, heat insulation and privacy protection while meeting the building energy-saving requirements.

[0029] For details, see attached. Figure 5-7As shown, the thermally insulated aluminum alloy window also includes an exhaust mechanism 4 connected and installed in the horizontal cavities on the upper and lower sides of the thermally broken aluminum frame 1. The exhaust mechanism 4 includes a U-shaped support frame 41. A plurality of first through holes 42 arranged in an array are provided on one side of the vertical wall of the support frame 41. A protrusion 43 is provided at the center of the top. A plurality of vertical second through holes 44 arranged in an array are provided at the center of the protrusion 43. Glass 2 is respectively connected and installed on both sides of the protrusion 43 at the top of the support frame 41. Two support plates 45 are connected and installed at both ends of the inner side of the support frame 41. An impeller 46 is rotatably connected between the two support plates 45. The support plates 45 are away from the impeller. A second motor 47 is connected and installed on one side of the impeller 46. The second motor 47 is a silent brushless motor. The output shaft of the second motor 47 is connected to the impeller 46. A rectifier 48 that is partially wrapped around the outside of the impeller 46 is also connected and installed between the two support plates 45. The air outlet of the rectifier 48 of the bottom exhaust mechanism 4 is aligned with the second through hole 44. The air outlet of the rectifier 48 of the top exhaust mechanism 4 is aligned with the first through hole 42. The top outdoor side of the thermally broken aluminum frame 1 is provided with a third through hole 49 that is coaxial with the first through hole 42. The bottom indoor side of the thermally broken aluminum frame 1 is provided with a third through hole 49 that is coaxial with the first through hole 42.

[0030] When in use, the second motor 47 at the bottom, as shown... Figure 5 The counter-clockwise rotation shown causes the impeller 46 to rotate counter-clockwise. The impeller 47 draws air from the room through the first through-hole 42 and the third through-hole 49, creating a vortex in the center of the impeller 47. Because the other half of the impeller 47 is obscured by the shroud 48, the flow field inside the impeller 47 changes, with the vortex center shifting towards the air outlet. The vortex center has a high wind speed, which in turn drives the surrounding air to form a through-flow, continuously entering the space between the glass panes through the second through-hole 42. Simultaneously, as... Figure 6 As shown, the second motor 47 at the top starts and, using the same working principle, draws the air between the glass 2 out through the second through hole 42, and discharges it to the outside through the first through hole 42 and the third through hole 49, thereby refreshing the indoor air and circulating fresh air into the room.

[0031] Preferably, both glass panes 2 are double-layered argon-filled glass. Argon has a higher density and dynamic viscosity than air, but a lower thermal conductivity and specific heat capacity. When filled into the insulating glass, it can slow down heat convection and heat conduction within the insulating glass, thereby reducing the overall thermal conductivity of the insulating glass and lowering the heat transfer coefficient, thus improving its heat insulation performance.

[0032] Among them, a curved polytetrafluoroethylene (PTFE) lubricating pad 51 is provided at the relatively inner corner of the vertical part of the two glass 2. PTFE has excellent self-lubricating properties, which can provide lubrication for the heat insulation film 36 sliding between the glass 2, reduce friction, keep the heat insulation film 36 quiet during stable sliding, and the curved surface can support the heat insulation film 36, keeping the heat insulation film 36 in the center of the gap between the two glass 2, preventing the heat insulation film 36 from contacting the glass 2 and increasing the resistance, so that the heat insulation film 36 slides more smoothly between the glass 2.

[0033] The rectangular opening 37 is surrounded by polytetrafluoroethylene lubricating blocks 54. These blocks reduce the resistance during the sliding of the heat insulation film 36 and prevent the film from being scratched.

[0034] The first motor 32 is a miniature servo motor. The servo motor can control the rotation angle of the motor with high precision, thereby keeping the heat insulation film 36 in a taut state between the glass 2, preventing wrinkles from forming in the heat insulation film 36 and making it more aesthetically pleasing.

[0035] Among them, the heat insulation film 36 consists of several types of films spliced ​​together in sequence, including light-blocking film, heat-insulating transparent film, transparent film, and frosted film, and even some patterns and text symbols are added. It can bring users more usage options, enrich the user experience, meet different heat insulation needs while ensuring privacy, and can also be programmed to automatically switch between different scenarios as needed.

[0036] Among them, such as Figure 2 As shown, a thermal insulation strip 52 is filled between the inner side of the cavity of the thermally broken aluminum frame 1 and the protective cylinder 33. By setting the thermal insulation strip 52, the air circulation flow is reduced, the thermal conductivity is reduced, and the thermal insulation performance is further improved.

[0037] One-way valves 53 are provided on the outer side of the third through hole 49. The one-way valves 53 can only allow air to flow from the indoor side to the outdoor side. This ensures that when the exhaust mechanism 4 is not working, outdoor air cannot enter the room, which can prevent thermal convection between indoor and outdoor air and reduce the heat insulation effect. Moreover, it can ensure that when the exhaust mechanism 4 is working, air can flow smoothly from indoor to outdoor. The one-way valves 53 on the outdoor side can also ensure that rainwater will not enter the aluminum alloy frame when it rains.

[0038] The support frame 41 is a PA66 nylon strip. The PA66 nylon strip has high strength, which can provide support for the glass 2, and also has good heat insulation ability, ensuring the overall heat insulation effect.

[0039] In summary, this heat-insulating aluminum alloy window, by setting an adjustable heat insulation film 36, allows users to select the type of heat insulation film 36 according to the indoor and outdoor environment or user needs, providing a more comfortable indoor environment. In conjunction with the exhaust mechanism 4, it actively exhausts indoor air, silently achieving indoor air circulation and creating a more comfortable environment.

[0040] When installing this insulated aluminum alloy window, a power cord wiring port needs to be reserved in the window. First, install and fix the upper and lower exhaust mechanisms 4 inside the thermally broken aluminum frame 1. Cover the exhaust mechanism 4 with the support frame 41. Then install one of the glass panes. Next, fix the thermal insulation mechanisms 3 on the left and right sides of the thermally broken aluminum frame 1 in place. Lead the wires out from the reserved wire conduit and connect them to the controller. Then install the other glass pane in place and fix it firmly.

[0041] The controller can be a common PLC controller, such as the Siemens S7-200smart series. By setting the program, it can realize the automated operation of the heat insulation mechanism and the exhaust mechanism according to the indoor and outdoor temperature and humidity. It can be intelligently connected to the voice AI assistant to realize voice control, further improving the automation level of the device.

[0042] It should be noted that the handles and hinges of this insulated aluminum alloy window are common existing technologies, and will not be described in detail here.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
