Description

Technical Field

[0001] This application relates to the field of curtain and window curtain structure technology, and in particular to a curtain and window curtain structure that facilitates lighting and heating. Background Technology

[0002] Curtains are a type of interior decoration that are typically installed in conjunction with window glass in buildings. Their main function is to separate the interior from the exterior to maintain the privacy of the interior. Curtains can achieve the effect of complete blackout or partial light transmission by choosing appropriate materials and patterns, thus adapting to the different light intensities required by different environments.

[0003] In winter, being near a window makes you feel cold because heat is constantly lost from the window glass through heat conduction, convection, and radiation, resulting in a lower window glass temperature. When the window glass temperature drops to a certain point, it exhibits a cold radiation effect: when you are near a window, your body heat is transferred to the window glass surface through radiation and absorbed by the cooler glass, causing continuous heat loss, a drop in perceived temperature, and the resulting "chilly" discomfort.

[0004] Conventional curtains and window curtains only block light and cannot prevent heat loss from the body, causing people sitting or working near windows to feel cold and experience reduced comfort. This is especially true for buildings in the Northern Hemisphere, where north-facing windows receive almost no direct sunlight in winter, preventing solar radiation from heating the glass surface. This results in the window glass remaining cold and damp for extended periods, causing significant discomfort to those near the windows, impacting efficiency and even health. Using thick curtains for insulation, however, blocks most of the light, leading to insufficient natural light inside the building. Summary of the Invention

[0005] The purpose of this application is to provide a curtain and window curtain structure that facilitates lighting and heating, aiming to improve the problem that curtain and window curtain structures in related technologies cannot simultaneously achieve both lighting and heating, and to increase the comfort of using curtain and window curtain structures.

[0006] On one hand, this application provides a curtain that facilitates light and heat transmission, including a track beam, a heating film disposed on the track beam, and a blackout curtain; the heating film includes a side support assembly, a base film disposed on the side support assembly, and a plurality of heating grid lines disposed on the base film; the side support assembly includes a first busbar and a second busbar, and the base film is laid along the length direction of the first busbar and the second busbar; the plurality of heating grid lines are disposed along the length direction of the first busbar and the second busbar, and the heating grid lines are electrically connected to the first busbar and the second busbar, and there is a light-transmitting space between the plurality of heating grid lines; the side support assembly, the heating grid lines, and the base film are coated with an encapsulating film.

[0007] Furthermore, the heating grid line includes an ink layer disposed on the base film. The ink layer is coated onto the surface of the base film by screen printing, coating or spraying. One end of the ink layer is connected to the first busbar, and the other end of the ink layer is connected to the second busbar. The ink layer is made by mixing and grinding micro-nano conductor materials and adhesives.

[0008] Furthermore, the micro / nano conductor material includes at least one of micro / nano carbon materials, micro / nano metal materials, and micro / nano alloy materials; the micro / nano carbon materials include graphene, carbon nanotubes, carbon nanofibers, carbon black, and micro / nano graphite powder.

[0009] Furthermore, micro / nano metallic materials include micro / nano nickel powder and micro / nano molybdenum powder; micro / nano alloy materials include nickel-chromium alloy powder, iron-chromium-aluminum alloy powder, molybdenum-silicon alloy powder, and copper-nickel alloy powder.

[0010] Furthermore, the adhesive includes a water-soluble adhesive and an organic solvent-soluble adhesive, the water-soluble adhesive being made of CMC and the organic solvent-soluble adhesive being made of PVDF.

[0011] Furthermore, the spacing of the heating grid lines is 30mm-60mm, and the thickness of the heating grid lines is 0.1mm-2mm.

[0012] Furthermore, the encapsulation membrane is sealed and covered on both sides of the surface of the side support assembly, the heating grid line, and the base film by a sealing adhesive.

[0013] Furthermore, the sealing adhesive includes an APAO hot melt adhesive layer coated on both sides of the side support assembly, the heating grid line, and the base film surface, and the encapsulation film covers the APAO hot melt adhesive layer.

[0014] Furthermore, the base film includes a polymer film, which includes a PET film layer and a polyimide film layer.

[0015] On the other hand, this application provides a window curtain structure, including a window frame, window glass disposed on the window frame, and a window curtain disposed on one side of the window glass, wherein the window curtain is a type of curtain that facilitates lighting and heating as described above.

[0016] The beneficial effects of this application are: 1. This application discloses a curtain that facilitates both lighting and heating. By installing a heating film and a blackout curtain on the track beam, light can be blocked by lowering the blackout curtain when light needs to be blocked. When heating is required, the heating film forms an electrical circuit with the heating grid lines through its first and second busbars. As current passes through the heating grid lines, they continuously generate heat, forming a thermal barrier. This thermal barrier significantly reduces heat loss through the window glass, providing warmth to people near the curtain. Simultaneously, the light-transmitting space between the heating grid lines allows light to pass through the base film and into the room. Rolling up the blackout curtain ensures both heating and lighting. The curtain is simple and convenient to use, effectively combining heating and lighting functions, and improving the comfort of occupants.

[0017] 2. A curtain for facilitating light and heat transmission according to this application, by setting a wrapping film, covers the side support components, base film, heating grid lines and the wrapping film. The wrapping film can seal and protect the internal structure, thereby effectively preventing external cold and humid air from penetrating into the internal structure and causing grid line oxidation or circuit failure. At the same time, the wrapping film can maintain stable bonding force under high temperature working conditions, avoiding cracking caused by material thermal expansion, and ensuring electrical safety and heat conduction efficiency during long-term use of the curtain.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0023] Example 1 On the one hand, refer to Figure 1 as well as Figure 2 This application proposes a curtain that facilitates lighting and heating, including a track beam 1, a heating film 2 disposed on the track beam 1, and a blackout curtain (not shown in the figure). The blackout curtain is rolled up inside the track beam 1 and can be unrolled and stored. When heating is needed, the blackout curtain is rolled up and the heating film 2 is activated. The heating film 2 is energized and continuously generates heat to reduce the loss of indoor heat through the window glass, while simultaneously heating nearby people. While providing heating, the heating film 2 can ensure lighting effect. When blackout is needed, the blackout curtain is unrolled, and the blackout curtain blocks the light.

[0024] Reference Figure 2 , Figure 3 , Figure 4 as well as Figure 5Specifically, the track beam 1 is used to support and install the heating film 2 and the light-blocking curtain, and the heating film 2 and the light-blocking curtain can be rolled up and operated independently to adapt to different scenario needs. The track beam 1 can be made of aluminum alloy profile or stainless steel profile. In this embodiment, the track beam 1 includes a double-groove track 11, which has a first groove 111 and a second groove 112. The first groove 111 and the second groove 112 are parallel to each other and extend along the length direction of the double-groove track 11. The first slide groove 111 is used to install the heating film 2. A winding assembly 12 is provided in the first slide groove 111. The winding assembly 12 includes bearing seats 121 at both ends of the first slide groove 111. A winding rod 122 is rotatably connected between the bearing seats 121. Both ends of the winding rod 122 have journals that cooperate with the bearing seats 121. One end of one of the bearing seats 121 is provided with a drive motor 123 for driving the winding rod 122. The journal of the winding rod 122 is coaxially mounted with the output shaft of the drive motor 123. The upper end of the heating film 2 is connected to the winding rod 122. Under the drive of the drive motor 123, the winding rod 122 rotates, thereby driving the heating film 2 to be wound up and unwound.

[0025] The second slide groove 112 is used to install the blackout curtain. Several sliding rings 13 are slidably connected to the second slide groove 112 along its length. Each sliding ring 13 includes a pulley 131, a connecting post 132, and a hanging ring connected in sequence. The pulley 131 is installed on the second slide groove 112 and slidably connected to the second slide groove 112. Several hanging rings are connected to the upper end of the blackout curtain. By sliding several sliding rings 13, the blackout curtain can be driven to stretch and be stored and pulled out for use. Both the blackout curtain and the sliding rings 13 are existing technologies and can be purchased. Their specific structure and working principle will not be described in detail.

[0026] Reference Figure 6 The heating film 2 includes a side support assembly 21, a base film 22 disposed on the side support assembly 21, and a plurality of heating grid lines 23 disposed on the base film 22. The side support assembly 21 provides support for the base film 22 and the heating grid lines 23. The side support assembly 21 includes a first busbar 211 and a second busbar 212, which are electrically connected to an external power supply device. When the power supply device is started, it can provide current to the first busbar 211 and the second busbar 212. In this embodiment, the first busbar 211 and the second busbar 212 can be made of Sn60Pb40 tin wire, so as to facilitate winding with the take-up and unwinding rod 122.

[0027] The base film 22 is laid along the length of the first busbar 211 and the second busbar 212, covering the space between them. The base film 22 serves to enable light transmission and support the heating grid lines 23. The base film 22 comprises a polymer film, which, through material combinations, satisfies both light transmittance and heat resistance requirements. In this embodiment, the polymer film includes a PET film layer and a polyimide film layer. PET film (polyethylene terephthalate film) is a high-performance polymer film with excellent physical and chemical properties. It is a colorless and transparent film that ensures light transmission through the base film 22, possesses good airtightness, and is resistant to high and low temperatures, chemicals, and oils. Simultaneously, it has excellent electrical insulation properties, maintaining good electrical insulation even under high-temperature and high-frequency environments. PET film has high tensile strength, flexural strength and impact strength, exhibits excellent creep resistance and fatigue resistance, can adapt to the rolling and unfolding of the heated film 2, and can remain stable under long-term load conditions.

[0028] Polyimide film is a colorless and transparent film with outstanding high-temperature resistance, radiation resistance, chemical corrosion resistance, and electrical insulation properties. It can be used for extended periods in air at 250–280°C, ensuring stable operation of the base film 22 while maintaining light transmission. Polyimide is chemically stable and resistant to corrosion from chemical solvents such as hydrocarbons, esters, ethers, alcohols, and chlorofluorocarbons. Polyimide film has good flame-retardant properties and is flame-retardant without the need for added flame retardants, effectively preventing softening or deformation of the base film 22 due to heating of the thermal grid lines 23.

[0029] Specifically, the PET film layer, as the main light-transmitting part of the base film 22, allows light to enter the room through the light-transmitting space, while its low coefficient of thermal expansion reduces deformation caused by temperature changes. The polyimide film layer, laminated onto the surface or in the interlayer of the PET film layer, utilizes its high-temperature resistance to maintain the structural rigidity of the base film 22 when the heating grid line 23 is continuously heating, preventing interlayer peeling or shrinkage caused by high temperatures. The two films are laminated or co-extruded with an adhesive to form a composite structure, maintaining uniform light transmittance in the light-transmitting area while providing thermal stability support in the high-temperature area. Understandably, the polyimide film layer can also be laminated onto the high-temperature sensitive areas of the PET film layer in a localized manner to achieve structural stability in the high-temperature area, such as near the edge of the heating grid line 23. The base film 22 achieves a balance between light transmittance, flexibility, and heat resistance by selecting specific materials for lamination.

[0030] The heating grid line 23 is used to cooperate with the first busbar 211 and the second busbar 212 to form a circuit to achieve heating. A plurality of heating grid lines 23 are arranged along the length direction of the first busbar 211 and the second busbar 212, and the heating grid lines 23 are electrically connected to the first busbar 211 and the second busbar 212. The first busbar 211 is a positive busbar, and the second busbar 212 is a negative busbar. When energized, the first busbar 211, the second busbar 212, and the heating grid lines 23 form a circuit, allowing current to flow through the heating grid lines 23, thus generating heat.

[0031] Specifically, the heating grid line 23 includes an ink layer disposed on the base film 22. The ink layer is coated onto the surface of the base film 22 by screen printing, coating, or spraying. One end of the ink layer is connected to the first busbar 211, and the other end of the ink layer is connected to the second busbar 212 to form a current loop. The ink layer is made by mixing and grinding micro-nano conductive materials and adhesives. The micro-nano conductive materials include at least one of micro-nano carbon materials, micro-nano metal materials, and micro-nano alloy materials. The micro-nano carbon materials include graphene, carbon nanotubes, carbon nanofibers, carbon black, and micro-nano graphite powder; the micro-nano metal materials include micro-nano nickel powder and micro-nano molybdenum powder; and the micro-nano alloy materials include nickel-chromium alloy powder, iron-chromium-aluminum alloy powder, molybdenum-silicon alloy powder, and copper-nickel alloy powder. The adhesive includes a water-soluble adhesive and an organic solvent adhesive. The water-soluble adhesive is made of CMC (carboxymethyl cellulose), and the organic solvent adhesive is made of PVDF (polyvinylidene fluoride).

[0032] In this embodiment, the ink layer is a micro-nano carbon material ink layer, which is made of 70%-99% graphene slurry, 0%-15% DBE (mixed diester), 0%-15% carbon black, and 0.3%-1.5% PVDF to meet the requirements of better light transmittance, thermal radiation intensity, structural strength and heat resistance.

[0033] CMC is readily soluble in both cold and hot water, exhibiting pseudoplasticity. It possesses good film-forming properties, forming a flexible, transparent film after drying, stable at pH 3–11. When dissolving PVDF, appropriate heating promotes dissolution, with 60°C being the optimal temperature. Complete dissolution results in a transparent, viscous solution. The dried film is transparent with a smooth surface. The tensile strength of the dried film is 30–50 MPa, and the elongation at break is 50–300%. It exhibits strong adhesion to metals (aluminum, copper), ceramics, and carbon materials (peel strength 0.5–5 N / cm), high cohesive strength, and is not easily broken. The solvent evaporation temperature of the PVDF solution is 80–120°C. The film withstands long-term temperatures from -40°C to 150°C. The thermal shrinkage rate is <5%, and it is dimensionally stable at 150°C. The adhesive made of CMC and PVDF can meet the requirements of thermal application of coatingable and printable ink when the thermal grid line 23 is prepared using micro-nano conductor materials, and at the same time meet the requirements of the bonding strength between the thermal grid line 23 and the base film 22.

[0034] It is worth mentioning that the thermal grid line 23 uses graphene, which can generate thermal radiation when energized. The thermal radiation is far-infrared radiation with a wavelength of 3 to 15 μm. According to literature, the peak wavelength of human radiation is 9.35 μm, which is in the far-infrared band and accounts for more than 80% of the total human radiation energy [Gao Mengyu, Zheng Rujun, Liu Ling. Research on the application of infrared forehead thermometers and mercury thermometers in adult febrile patients [J]. Nursing Research, 2014, 28(30):3808-3810]; According to the principle of "spectral matching resonance", literature records that far-infrared rays with wavelengths of 4-14 μm are of great significance to human survival and health [Cheng Wenhui et al. Observation on the effect of infrared forehead thermometers and mercury thermometers in clinical use [J]. Journal of Luzhou Medical College, 2014, 37(6):610-611]; and according to the theory of "matching absorption", the infrared radiation spectrum has characteristic absorption bands; the skin's surface absorption band is 5.9-7 μm, 8-12 μm. Experiments show that when the infrared radiation band is 4-6 μm, the irradiance is 0.1 W / cm-2, and the irradiation distance is 10-15 cm, the subcutaneous temperature can be 3-5 °C higher than the surface temperature [Wu Wei, et al., Infrared Medicine [J]. Infrared Technology, 1998, Vol. 20, No. 5].

[0035] That is, the human body continuously absorbs infrared light from the outside world. When the heating film 2 is energized, it generates infrared radiation with a wavelength of 3 to 15 μm through graphene. This allows the heating film 2 to be effectively matched according to the characteristics of the human body, so that the human body can better absorb infrared radiation, effectively raise the body temperature and make the warmth more noticeable, thereby improving comfort and user experience.

[0036] The heating grid lines 23 utilize an ink coating to form a predetermined resistance value. When energized, the current is shunted through the first busbar 211 to each heating grid line 23 and then converges into the second busbar 212. The ink coating generates heat uniformly through the resistance effect, forming a heat radiation layer parallel to the window surface. The generated heat establishes a heating layer between the window glass and the indoor space, thereby effectively suppressing the cold radiation effect. By using composite graphene slurry, DBE, and carbon black, this application can improve the conductivity and heating uniformity of the heating grid lines 23, reduce the risk of oxidation loss under high-temperature environments, enhance the mechanical strength and heat resistance of the materials, and ensure the reliability of the heating function of the heating film 2.

[0037] To ensure light transmission of the heating film 2, there are light-transmitting spaces between several heating grid lines 23. These light-transmitting spaces refer to the areas between adjacent heating grid lines 23, allowing natural light to penetrate the base film 22 and maintaining indoor lighting when the blackout curtain is retracted. Simultaneously, light transmittance can be ensured by controlling the grid line spacing. To achieve better light transmission, the spacing of the heating grid lines 23 is 30mm-60mm, and the thickness of the heating grid lines 23 is 0.1mm-2mm. The spacing of the heating grid lines 23 refers to the distance between the center lines of two adjacent heating grid lines 23. This can be achieved by controlling the ink layer distribution using a screen printing process. By controlling the spacing of the heating grid lines 23 within the range of 30mm to 60mm, a spaced conductive heating structure can be formed on the surface of the base film 22. Sufficiently wide light-transmitting areas are maintained between adjacent heating grid lines 23 for natural light to penetrate, while ensuring that the heating element distribution density is sufficient to form a continuous heat barrier.

[0038] The thickness of the heating grid lines 23 refers to the vertical height of the ink layer on the surface of the base film 22. This thickness can be achieved by adjusting the screen printing squeegee pressure or coating process parameters. This thickness ensures that the required conductive cross-sectional area for current transmission is met to stably generate Joule heat, while avoiding excessive thickness that could lead to decreased light transmittance of the base film 22 or breakage during film curling. By optimizing the matching relationship between the density of the heating grid lines 23 and the conductive cross-sectional area, the heating film 2 achieves uniform heating while maintaining light transmission. This allows the heating film 2 to form a uniformly distributed thermal field in cold environments, effectively reducing heat loss through window glass while maintaining sufficient light-transmitting area for natural light penetration. This ensures that indoor lighting is not sacrificed during heating, improving the comfort of people near the window area.

[0039] To ensure operational stability, the side support assembly 21, the heating grid lines 23, and the base film 22 are coated with an encapsulation film 24. The encapsulation film 24 is sealed and covered on both the front and rear sides of the side support assembly 21, the heating grid lines 23, and the base film 22 using a sealing adhesive. Specifically, the encapsulation film 24 can be made of the same polymer material as the base film 22, thereby forming a sealed structural layer on the surface of the heating film 2, which seals and protects the internal side support assembly 21, base film 22, and heating grid lines 23 from oxidation and external physical damage.

[0040] A sealing adhesive is used to fix the encapsulation membrane 24 to the heating film 2. Specifically, the sealing adhesive can be APAO hot melt adhesive, which includes an APAO hot melt adhesive layer coated on both sides of the side support assembly 21, the heating grid lines 23, and the base film 22. The encapsulation membrane 24 is covered by the APAO hot melt adhesive layer. APAO (Amorphous Poly Alpha Olefin) hot melt adhesive is a high-performance thermoplastic adhesive with a unique amorphous structure. It is colorless and transparent, with a low density (approximately 0.85–0.92 g / cm³), low viscosity in the molten state, good flowability, and easy to coat or spray. APAO hot melt adhesive has strong adhesion to non-polar materials (such as PP, PE, PET, etc.), strong cohesion, good impact resistance and creep resistance; good weather resistance; excellent UV and oxidation resistance; does not easily discolor after long-term use; good hydrolysis resistance; and excellent stability to acids, alkalis, oils, and other media.

[0041] By using APAO (Amorphous Poly Alpha Olefin) hot melt adhesive to form a hot melt adhesive layer on the surface, the bonding requirements between the base film 22 and the encapsulation film 24 can be effectively met. After bonding, the mechanical strength of the infrared heating film 2 is maintained, thus meeting the requirement of achieving light transmission on a sealed basis. The sealed structure formed by the encapsulation film 24 can block external moisture and oxygen from contacting the heating grid line 23, avoiding resistivity changes or failure of the grid line material due to oxidation or moisture, thereby maintaining the stability of the light transmission space.

[0042] By setting up the heating film 2, compared to simply thickening the curtains or using blackout curtains alone, it avoids completely blocking the light. The heating film 2 generates heat to compensate for heat loss in the window area, and the heat source acts directly on the window surface, reducing energy transfer loss. It achieves both heating and lighting functions at the same time. Users can flexibly choose the blackout, lighting, or heating mode according to their environmental needs, and environmental optimization can be achieved without changing the existing window structure.

[0043] Example 2 On the other hand, this application provides a window curtain structure, including a window frame, window glass disposed on the window frame, and a curtain disposed on one side of the window glass. The curtain is a type of curtain as described above that facilitates lighting and heating. The window frame refers to the supporting structure used to fix the window glass and curtain, and can be implemented using aluminum alloy profiles or steel profiles. The rigid support of the frame ensures the stable installation of the window glass and curtain. The window glass can be double-glazed, allowing natural light to enter the room through the light-transmitting properties of the glass.

[0044] The window curtains are the aforementioned curtains that facilitate lighting and heating. By setting the window curtain structure in this way, the problem of conventional window curtain structures being unable to balance lighting and heating in winter is improved. This reduces heat loss near the window glass, suppresses the discomfort caused by cold radiation, and improves the comfort of people in cold environments.

[0045] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
