Description

Technical Field

[0001] This utility model relates to a double-layer window system and belongs to the field of building door and window technology. Background Technology

[0002] Traditional building windows have long played a crucial role in providing lighting, ventilation, and insulation. However, with the rapid development of renewable energy technologies, especially the rise of building-integrated photovoltaics (BIPV) technology, photovoltaic glass has emerged as an innovative building material. It has successfully transformed building facades into energy production units, providing new possibilities for energy conservation and sustainable development in buildings.

[0003] Nevertheless, existing designs for applying photovoltaic glass to windows generally have some limitations. Many designs use fixed photovoltaic glass windows, in which the photovoltaic glass can generate electricity, but the inward-facing surface of the photovoltaic glass generates a lot of heat when generating electricity, raising the indoor temperature, especially in summer, which can lead to overheating.

[0004] Therefore, how to cleverly combine the functions of photovoltaic glass with windows, and at the same time effectively utilize and handle the heat generated by photovoltaic glass through the design of flexible opening methods, has become one of the important challenges that the current construction industry urgently needs to solve. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a double-layer window system that provides users with a more efficient and practical window option. By introducing power-generating glass and diversified opening mechanisms, it can not only achieve energy self-sufficiency, but also effectively treat and utilize the heat generated by the power-generating glass during power generation.

[0006] The technical solution adopted by this utility model to solve its existing problems is:

[0007] A double-glazed window system includes a window frame comprising an outer frame and an inner frame.

[0008] The external frame is equipped with an external window sash, which can be flipped outward about the upper edge of the external frame. The external window sash includes power-generating glass.

[0009] The internal frame is fitted with an internal window sash, which can be opened and closed about the side edge of the internal frame. The internal window sash includes an inner window glass.

[0010] Preferably, the mounting positions of the shaft on the outer frame and the inner frame include, but are not limited to, the upper edge, the lower edge, and the side edge.

[0011] Preferably, a hinge mechanism and a locking mechanism are provided between the outer frame and the outer window sash, and between the inner frame and the inner window sash. The outer window sash is connected to the outer frame through the hinge mechanism and the locking mechanism, and the inner window sash is connected to the inner frame through the hinge mechanism and the locking mechanism.

[0012] Preferably, the internal window sash can be tilted inward with the lower edge of the internal frame as the axis.

[0013] Preferably, the internal window sash can be opened about the side edge of the internal frame.

[0014] Preferably, the inner frame side edge is equipped with a casement and tilt-in axis, so that the inner window sash can be casemented and tilted inward with the inner frame side edge as the axis.

[0015] Preferably, the external window sash can be flipped outward with the upper edge of the external frame as the axis.

[0016] Preferably, the power-generating glass of the external window sash is connected to a battery for collecting the electrical energy generated by the power-generating glass.

These terms are used only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In this utility model, unless otherwise expressly specified and limited, terms such as "installed," "connected," "joined," and "fixed" should be interpreted broadly. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0026] like Figure 1 and Figure 2 The illustrated double-glazed window system includes a window frame comprising an outer frame 1 and an inner frame 5. An outer window sash 2 is mounted on the outer frame 1 and is capable of being tilted outwards about a pivot point on the outer frame 1. The outer window sash 2 includes a heat-generating glass 4. An inner window sash 6 is mounted on the inner frame 5 and is capable of being opened and closed about a pivot point on the inner frame 5. The inner window sash 6 includes an inner window glass 7. The mounting positions of the pivot point on the outer frame 1 and the inner frame 5 include, but are not limited to, the upper edge, the lower edge, and the side edge.

[0027] Hinges and locking mechanisms are provided between the outer frame 1 and the outer window sash 2, and between the inner frame 5 and the inner window sash 6. The outer window sash 2 is connected to the outer frame 1 through the hinge and locking mechanisms, and the inner window sash 6 is connected to the inner frame 5 through the hinge and locking mechanisms.

[0028] Sealing strips are provided between the outer frame 1 and the outer window sash 2, and between the inner frame 5 and the inner window sash 6, to ensure good airtightness and watertightness. The outer frame 1 and the inner frame 5 can be integrated into a single window frame, or they can be two tightly connected independent frames. The window frame materials can be commonly used aluminum alloy, PVC, wood, or composite materials.

[0029] The external window sash 2 is designed to flip outwards, achieving optimal solar energy absorption in the flipped-out state. This allows for more efficient conversion of sunlight into electricity, increasing energy output. The power-generating glass 4 of the external window sash 2 is connected to a battery to collect the electrical energy generated by the power-generating glass. The power-generating glass 4 can be a building-integrated photovoltaic (BIPV) glass unit, such as laminated or hollow photovoltaic glass, which integrates photovoltaic cells or photovoltaic films. The power-generating glass 4 is typically connected to wires that extend through the window frame or a dedicated channel to a junction box, so that the generated electrical energy can be transmitted to the building's power system or energy storage equipment.

[0030] The inner window sash 6 can be fitted with vacuum glass, double-glazed glass, or laminated glass, including but not limited to these types. Vacuum glass, double-glazed glass, or laminated glass effectively insulates heat and reduces noise, maintaining a comfortable and quiet indoor environment. An electric heating film can be installed on the inner window sash 6. This film is a material that generates heat when electricity is applied, and its function is to heat the inner window sash 6, preventing fogging and frost formation on the glass surface and increasing the indoor temperature. The electric heating film is connected to the power-generating glass 4. The electric heating film is adhered to the inner window sash 6, either directly connected to the power-generating glass 4 or connected to it via a battery. With the electric heating film directly connected to the power-generating glass 4, the electrical energy generated by the power-generating glass 4 can be directly supplied to the electric heating film, forming a closed-loop "power generation-heating" system that requires no external power grid. The electric heating film is connected to the power generation glass 4 via a storage battery. The power generation glass first stores electrical energy in the storage battery, and then the storage battery supplies power to the electric heating film. The advantage of this design is that the storage battery can buffer the electrical energy, avoid the impact of unstable power generation of the power generation glass (such as insufficient light) on the heating function, and ensure the continuous operation of the system.

[0031] Example 1:

[0032] The hinge mechanism between the inner frame 5 and the inner window sash 6 includes a hinged hinge that opens and tilts inward. The hinge that opens and tilts inward is installed on the side edge of the inner frame 5, allowing the inner window sash 6 to open and tilt inward with the side edge of the inner frame 5 as the axis. The outer window sash 2 can tilt outward with the upper edge of the outer frame 1 as the axis.

[0033] The outer window sash 2 is equipped with an outer handle 3, which connects to the locking mechanism between the outer frame 1 and the outer window sash 2. The inner window sash 6 is equipped with an inner handle 8, which connects to the locking mechanism between the inner frame 5 and the inner window sash 6. The hinge mechanism and locking mechanism are used to control the opening, closing, and locking of the outer window sash 2 and the inner window sash 6. To open or close the outer window sash 2, the inner window sash 6 must first be opened using the inner handle 8, and then the outer window sash 2 can be opened or closed using the outer handle 3.

[0034] When both the outer window sash 2 and the inner window sash 6 are closed, an air gap exists between them, which helps improve the thermal insulation and sound insulation performance of the entire window system. The outer window sash 2 can be tilted outwards, and the inner window sash 6 can be opened inwards, exposing the outer window sash 2, the inner window sash 6, and the air gap between them, facilitating cleaning or ventilation.

[0035] To improve indoor safety, space utilization, and dust and rain protection, the inner window sash 6 needs to be adjusted to the tilt-in position. To switch the window sash from the closed state, turn the inner handle 8 to the tilt-in position of the inner window sash 6, and pull the inner handle 8 to adjust the inner window sash 6 to the tilt-in position.

[0036] Example 2:

[0037] The inner window sash 6 can tilt inwards with the lower edge of the inner frame 5 as the axis. The outer window sash 2 can tilt outwards with the upper edge of the outer frame 1 as the axis.

[0038] The outer window sash 2 is equipped with an outer handle 3, which connects to the locking mechanism between the outer frame 1 and the outer window sash 2. The inner window sash 6 is equipped with an inner handle 8, which connects to the locking mechanism between the inner frame 5 and the inner window sash 6. The hinge mechanism and locking mechanism are used to control the opening, closing, and locking of the outer window sash 2 and the inner window sash 6. To open or close the outer window sash 2, the inner window sash 6 must first be tilted inward using the inner handle 8, and then the outer window sash 2 can be opened or closed using the outer handle 3.

[0039] When both the outer window sash 2 and the inner window sash 6 are closed, an air gap exists between them, which helps improve the thermal insulation and sound insulation performance of the entire window system. The outer window sash 2 can be tilted outwards, and the inner window sash 6 can be tilted inwards, exposing the outer window sash 2, the inner window sash 6, and the air gap between them, facilitating cleaning or ventilation.

[0040] Example 3:

[0041] The inner window sash 6 can be opened horizontally with the side edge of the inner frame 5 as the axis. The outer window sash 2 can be turned outward with the upper edge of the outer frame 1 as the axis.

[0042] The outer window sash 2 is equipped with an outer handle 3, which connects to the locking mechanism between the outer frame 1 and the outer window sash 2. The inner window sash 6 is equipped with an inner handle 8, which connects to the locking mechanism between the inner frame 5 and the inner window sash 6. The hinge mechanism and locking mechanism are used to control the opening, closing, and locking of the outer window sash 2 and the inner window sash 6. To open or close the outer window sash 2, the inner window sash 6 must first be opened using the inner handle 8, and then the outer window sash 2 can be opened or closed using the outer handle 3.

[0043] When both the outer window sash 2 and the inner window sash 6 are closed, an air gap exists between them, which helps improve the thermal insulation and sound insulation performance of the entire window system. The outer window sash 2 can be tilted outwards, and the inner window sash 6 can be opened in a casement manner, exposing the outer window sash 2, the inner window sash 6, and the air gap between them, facilitating cleaning or ventilation.

[0044] In the above embodiments, the hinge mechanisms and locking mechanisms that control the opening, locking, casement and tilting of the outer window sash 2 and the inner window sash 6 can all be implemented using standard window hardware, such as dedicated casement and tilting hardware. These hardware typically include operating handles, transmission rods, locking points and hinges, etc., and the opening angle can be limited or infinitely adjusted as needed.

[0045] In this application, users can manually adjust the opening status of the external window sash 2 and the internal window sash 6 using the external handle 3 and the internal handle 8 to achieve optimized thermal energy management. When the power-generating glass 4 is in operation, and both the external window sash 2 and the internal window sash 6 are closed, the air gap between the external window sash 2 and the internal window sash 6 contains the heat generated by the power-generating glass 4, which can raise the indoor temperature. If the user wants to further raise the indoor temperature, the user can open the internal window sash 6 to allow the generated heat to dissipate into the room, further raising the indoor temperature. If the user does not want the heat generated by the power-generating glass 4 to enter the room, the user can adjust the external window sash 2 to the outward tilt position and then close the internal window sash 6. The heat generated by the power-generating glass 4 of the external window sash 2 will then dissipate into the outside air, preventing heat from entering the room. By combining the adjustable opening states of the external window sash 2 and the internal window sash 6 with the solar power generation design of the external window sash 2, the system not only improves the energy self-sufficiency capability, but also enables the heat generated during the power generation process of the power-generating glass to be discharged outdoors in summer and stored indoors in winter, thus enhancing the temperature comfort of the indoor environment. Users can flexibly adjust the window state according to the actual weather and indoor needs to achieve more efficient energy utilization.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
