Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to a low-carbon, green double-layer window based on passive energy-saving technology. Background Technology

[0002] Double-glazed sliding windows refer to sliding windows with a double-layered glass structure. These windows separate two layers of glass with a spacer, forming a hollow cavity. Double-glazed sliding windows not only offer excellent sound and heat insulation but also provide a more comfortable living environment and effectively reduce energy consumption, making them a widely used energy-saving and environmentally friendly window product in modern buildings. In existing technologies, patent CN204511253U proposes a centrally located sunshade integrated double-glazed window, which sets a sunshade curtain in the middle of the double-glazed sliding window to improve the window's shading effect, but its function is limited. Patent CN207553933U proposes an energy-saving, sun-shading, green window and door structure that installs solar panels on the window frame for energy storage; however, the installation location of the solar panels is bulky and unsafe. Summary of the Invention

[0003] The purpose of this invention is to propose a low-carbon, green double-layer window based on passive energy-saving technology to enhance the functionality of double-layer windows, integrating functions such as energy storage, sun shading, active ventilation, and air purification into the window.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A low-carbon, green, double-layered window based on passive energy-saving technology includes a frame and two window panels located inside the frame. The two window panels include an outer first window panel and an inner second window panel. The first window panel includes an outer first window panel and an inner first window panel, and the second window panel includes an inner second window panel and an outer second window panel. The first outer window panel, the first inner window panel, the second inner window panel, and the second outer window panel are slidably connected to the frame via corresponding slide rails.

[0006] Furthermore, an intermediate curtain is installed between the first and second window panels. Retractors for unwinding and rewinding the intermediate curtain are installed at the top and bottom of the frame, respectively. The upper and lower ends of the intermediate curtain are wound around the corresponding retractors. The intermediate curtain includes multiple functional sections, each with a function matching the inner frame of the frame. The retractors perform corresponding winding and unwinding of the intermediate curtain, moving the intermediate curtain to the functional section matching the inner frame of the frame.

[0007] Preferably, the two side frames of the frame are respectively provided with limiting frames, which are used to limit the edge of the middle curtain and keep the middle curtain stable during winding.

[0008] Preferably, the functional sections of the intermediate curtain include a circulation section, an energy collection section, a louver section, a mesh section, and a purification section. The circulation section has through-holes that match the inner frame of the window, allowing for air circulation. The energy collection section has flexible solar panels that match the inner frame, absorbing solar energy and converting it into electricity for the window's operation via a configured energy conversion device. The louver section has louvers that match the inner frame for shading. The mesh section has a mesh surface that matches the inner frame for insulation. The purification section has a purification surface that matches the inner frame, including a filter in the center and sealing baffles on either side of the filter. The filter is a HEPA filter for purifying air entering the room from the outside.

[0009] Two isolation seats are also provided between the first and second window panels, located on either side of the intermediate curtain. The first isolation seat is located between the first window panel and the intermediate curtain, and the second isolation seat is located between the second window panel and the intermediate curtain. The frame is provided with receiving grooves for accommodating the first and second isolation seats. When the first and second isolation seats are not in operation, they are located within the receiving grooves. The first and second isolation seats are slidably connected to the frame. The sliding direction of the first and second isolation seats is the same as the sliding direction of the window panels.

[0010] The first and second isolation seats are each provided with multiple through-holes, and exhaust assemblies are installed at these holes. Each exhaust assembly includes an exhaust fan and an isolation belt. The exhaust fan is mounted inside the through-hole via a support frame; rotation of the exhaust fan creates airflow through the through-hole. The isolation belt is a closed loop, supported and conveyed by two support rollers, one above the exhaust fan and the other below it. The exhaust fan is located inside the isolation belt.

[0011] The isolation belt includes a heating mesh, an isolation mesh, and two connecting belts. The connecting belts are located between and connect the heating mesh and the isolation mesh. The heating mesh and the isolation mesh are partially located inside the flow hole and are located on both sides of the exhaust fan's airflow direction.

[0012] The isolation net is used to isolate the exhaust fan. The heating net can be electrically heated to heat the air in the flow holes, creating warm air delivery into the room. The isolation belt, through a conveyor system, can adjust the relative positions of the heating net and the isolation net when the exhaust fan changes its airflow direction in the flow holes, ensuring that the heating net is on the air outlet side when the exhaust fan is blowing air in both directions.

[0013] The double-layer window in this invention has the following states:

[0014] (1) When passive air circulation is required for the window, the first and second window panels are placed against the same side frame of the frame, and the circulation section of the middle curtain is located between the first and second window panels. Air circulates naturally between the indoor and outdoor areas through the circulation section. When mosquitoes need to be isolated, the circulation section can be converted into a mesh section.

[0015] (2) When the window needs to convert light energy, the energy collection section of the middle curtain is located between the first window panel and the second window panel. The flexible solar panel can be used to absorb light energy and convert the light energy into part of the electrical energy required for the operation of the window through the configured energy conversion component.

[0016] (3) When the window needs to be shaded, the venetian section of the middle curtain is located between the first window panel and the second window panel. The venetian section can be opened and closed for shading.

[0017] (4) When the window requires active air circulation, the first window panel is placed against the first side frame of the frame, and the second window panel is placed against the second side frame of the frame. The mesh section of the middle curtain is located between the first and second window panels. The first and second isolation seats are respectively positioned at the overlapping point between the first and second window panels. The mesh section, the first isolation seat, and the second isolation seat seal the gap between the first and second window panels. The exhaust fans of the first and second isolation seats respectively perform exhaust operations to send outdoor air into the room or send indoor air into the outside.

[0018] The exhaust fans on the first and second isolation seats can rotate partially forward and partially in reverse, for either forward or reverse airflow. When the indoor air temperature is low, the air entering the room can be heated through a heating grid to maintain indoor warmth.

[0019] (5) When the window is being purified and the air is supplied, the first outer window panel of the first window panel is placed against the first side frame of the frame, and the first inner window panel of the first window panel is not placed against any side frame. The second outer window panel of the second window panel is placed against the second side frame of the frame, and the second inner window panel of the second window panel is not placed against any side frame. The purification section of the middle curtain is located between the first window panel and the second window panel.

[0020] The first and second isolation seats move to the two sealing baffles in the purification section, respectively. The first isolation seat is located between the first inner window panel and the sealing baffle, and the second isolation seat is located between the second inner window panel and the sealing baffle. The filter screen is located between the first and second isolation seats. The exhaust fans of the first and second isolation seats operate in the same direction. External air enters the room sequentially through the gap between the first inner window panel and the second side frame, the first isolation seat, the filter screen, the second isolation seat, and the gap between the second inner window panel and the first side frame. The filter screen purifies the air, maintaining healthy air entering the room.

[0021] The beneficial effects of this invention are:

[0022] 1. This double-layer window has two layers of window panels with gaps between them, providing good thermal insulation. At the same time, a flexible solar panel is installed on the curtain between the two layers of window panels, which can convert and utilize the solar energy from the external wall, reducing the need for active energy supply. It has the functions of dynamic energy saving and low carbon emissions.

[0023] 2. The middle curtain of this double-layer window is equipped with multiple functional sections, which, combined with the isolation seat, enable the window to have the functions of light energy conversion, active ventilation and air purification, making it feature-rich and practical; during air purification, the purification filter is located on the middle curtain, making it easy to clean and replace.
