[0026] like Figures 1 to 5 As shown, an energy-saving door and window for green buildings includes a glass door frame 1, which includes a frame body 11. An inner glass 2 is vertically arranged on the side of the frame body 11 close to the interior of the room, and an outer glass 3 is vertically arranged on the side of the frame body 11 close to the exterior of the room. A color-changing glass 4 is vertically arranged between the inner glass 2 and the outer glass 3 in the frame body 11. A sealing frame 6 is vertically arranged on both sides of the inner glass 2, the outer glass 3 and the color-changing glass 4, and the sealing frame 6 is fixed on the inner wall of the frame body 11. The interior of the frame body 11 is located between the outer glass 3 and the color-changing glass 4. A shading member 5 is provided between the two parts, and the shading member 5 includes a pull plate 51 and a shading curtain 54. The pull plate 51 is vertically slidably assembled on the frame 11, and a shading curtain 54 is provided on the top surface of the pull plate 51. The bottom end of the shading curtain 54 is fixed on the top surface of the pull plate 51, and the top end of the shading curtain 54 is fixed on the top surface of the frame 11. The color-changing glass 4 adopts electrochromic glass, model AH001. When no voltage is applied to the color-changing glass 4, the electrochromic material is in the initial state, and the glass is transparent or translucent. When voltage is applied, ions (such as lithium ions Li + ) migrates from the transparent conductive layer to the electrochromic material layer under the action of the electric field, causing the optical properties of the material to change, making the glass darker or discolored. By changing the direction of the voltage or stopping the power supply, the electrochromic material can be restored to its original state, and the glass becomes transparent again. By adjusting the light transmittance, the energy consumption of air conditioning and lighting is reduced, the indoor light is kept appropriate, and the comfort of living and working is improved. In order to improve the thermal insulation of energy-saving doors and windows for green buildings, an inner glass 2, a color-changing glass 4 and an outer glass 3 are vertically arranged in the frame 11 of the glass door frame 1 from the inside to the outside. Two cavities are formed between the inner glass 2, the color-changing glass 4 and the outer glass 3. The cavity between the outer glass 3 is used to improve the heat insulation effect of energy-saving doors and windows. At the same time, in order to adjust the shading properties of energy-saving doors and windows for green buildings, the photochromic glass 4 adopts electrochromic glass. The voltage intensity of the photochromic glass 4 is manually controlled according to the changes in light. Its transparency is changed by applying voltage, thereby improving the shading properties of the glass door frame 1. At the same time, a shading member 5 is provided inside the frame 11 between the outer glass 3 and the photochromic glass 4. The shading member 5 can be extended and contracted vertically. When expanded, the pull plate 51 moves vertically downward to pull the shading curtain 54 downward. The expanded shading curtain 54 is used to block outdoor light from entering the room, thereby ensuring indoor comfort while reducing cooling consumption.
[0027] In one embodiment, Figure 2 and 4As shown, sliders 52 are horizontally provided at both ends of the pull plate 51, and the sliders 52 are fixed on the end faces of the pull plate 51, and slideways 12 are vertically opened on the vertical end faces on both sides of the interior of the frame 11, and an electric telescopic rod 53 is vertically provided inside the slide 12, and the top of the electric telescopic rod 53 is fixed on the bottom surface of the slider 52, and the bottom end of the electric telescopic rod 53 is fixed on the bottom surface of the slide 12. When shading is needed, the electric telescopic rod 53 is manually controlled to retract, driving the pull plate 51 to move vertically downward and pulling the blackout curtain 54 to extend downward. The unfolded blackout curtain 54 is used to block outdoor light from entering the room. On the contrary, when shading is not needed, the blackout curtain 5 is retracted and manually controlled. The electric telescopic rod 53 is stretched and pulled, driving the pulling plate 51 to move vertically upward and pulling the blackout curtain 54 to fold and stretch upward. The blackout curtain 54 is folded, and outdoor light enters the room. A flexible photovoltaic panel is adhered to the outer end face of the blackout curtain 54 close to the outside. The flexible photovoltaic panel is a solar panel made of flexible material. Compared with traditional rigid photovoltaic panels, the flexible photovoltaic panel has the characteristics of being light, flexible, and easy to install, which is convenient for later rolling and bending. When the blackout curtain 54 is lowered, the flexible photovoltaic panel is unfolded, and the unfolded flexible photovoltaic panel generates electricity with light, which is convenient for later shading. At the same time, the flexible photovoltaic panel absorbs light to generate electricity, so as to ensure green light while ensuring shading.
[0028] In one embodiment, Figure 2 and 3 As shown, the sealing frame 6 is provided with an embedding groove 61 on the vertical end face of one side close to the inner glass 2, the outer glass 3 and the photochromic glass 4, and a sealing gasket 62 is fixed in the embedding groove 61. In order to ensure that the inner glass 2, the outer glass 3 and the photochromic glass 4 are fixed and sealed in the frame body 11, a sealing frame 6 is provided on both sides of the inner glass 2, the outer glass 3 and the photochromic glass 4. The sealing frame 6 is fixed on the inner wall of the frame body 11, and then the sealing gasket 62 fixed between the sealing frame 6 and the inner glass 2, the outer glass 3 and the photochromic glass 4 seals the gap, thereby improving the sealing performance of the energy-saving doors and windows. The sealing gasket 62 is made of EPDM rubber, which has good elasticity, good gap filling, aging resistance, and a wide temperature resistance range, which is beneficial to improving the sealing weather resistance and service life of the doors and windows.
[0029] In one embodiment, Figure 2 and 5 As shown, the horizontal thread at the end of the frame 11 is assembled with a locking bolt 13, and the outer end surface of the frame 11 is filled with a thermal insulation cotton block 14. The frame 11 is locked and fixed to the wall by the locking bolt 13. At the same time, the outer wall sealing cavity of the frame 11 is filled with a thermal insulation cotton block 14. The thermal insulation cotton block 14 is used to increase the sealing and thermal insulation properties of the frame 11. The thermal insulation cotton block 14 is usually made of high-temperature resistant fiber material, and has good thermal insulation performance, light weight, fire resistance and other characteristics. They can effectively reduce heat transfer, thereby improving energy utilization efficiency and reducing energy consumption, and ensuring the thermal insulation properties of doors and windows.
[0030] In this embodiment, the frame 11 is locked and fixed to the wall by locking bolts 13, and the outer wall sealed cavity of the frame 11 is filled with insulation cotton blocks 14. The frame 11 of the glass door frame 1 in the energy-saving door and window is vertically arranged with inner glass 2, color-changing glass 4 and outer glass 3 from the inside to the outside. Two cavities are formed between the inner glass 2, the color-changing glass 4 and the outer glass 3. The cavity between the inner glass 2, the color-changing glass 4 and the outer glass 3 is used to improve the heat insulation effect of the energy-saving door and window. The color-changing glass 4 adopts electrochromic glass. The voltage intensity of the color-changing glass 4 is manually controlled according to the change of light. Its transparency is changed by applying voltage, thereby improving the light-shielding property of the glass door frame 1. At the same time, a shading member 5 is provided between the outer glass 3 and the color-changing glass 4 inside the frame 11. The shading member 5 can extend and retract vertically. When unfolded, the pull plate 51 moves vertically downward to pull the blackout curtain 54 downward. The unfolded blackout curtain 54 is used to block outdoor light from entering the room.
[0031] The above is a preferred embodiment of the present invention. Technicians in the field of the present invention can also change and modify the above embodiment. Therefore, the present invention is not limited to the above specific embodiment. Any obvious improvements, replacements or modifications made by technicians in this field on the basis of the present invention are within the scope of protection of the present invention.
