Description

Technical Field

[0001] This utility model belongs to the field of doors and windows, and specifically relates to a light-adjusting window based on electrochromic properties. Background Technology

[0002] Windows are mainly composed of a frame and glass, used to allow light into the room while isolating indoor and outdoor air. Currently, most window glass is transparent, which fails to block outside views, especially at night when lights are on, making it impossible to see inside the room without curtains. Furthermore, transparent glass allows a lot of light, which can cause excessive light pollution during the day when exposed to strong sunlight. Closing the curtains, on the other hand, can reduce natural light. Utility Model Content

[0003] In view of the problems in the related technologies, this utility model proposes a light adjustment window based on electrochromic light to overcome the above-mentioned technical problems existing in the existing related technologies.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a light-adjusting window based on electrochromic properties, including a window frame, with glass fixedly installed on both sides of the inner circle of the window frame, and an electrochromic film located between the glass on both sides of the inner circle of the window frame. The electrochromic film includes conductive electrode layers respectively disposed on the inner side of the two glass surfaces, and an electrochromic layer, an electrolyte layer and an ion storage layer are sequentially and tightly disposed between the two conductive electrode layers.

[0006] Both conductive electrode layers are composed of multiple electrode films, and the multiple electrode films in the two conductive electrode layers are arranged in a one-to-one correspondence. Each electrode film is connected to an independent power line, and the power line is connected to the power source through a voltage regulator and a relay.

[0007] Furthermore, an insulating groove is provided between adjacent electrode films, and the interior of the insulating groove is filled with transparent insulating adhesive.

[0008] Furthermore, a wiring frame is provided on the outer ring of the conductive electrode layer, and a relay corresponding to the electrode film is fixedly installed on the wiring frame. The electrode film on the outer ring of the conductive electrode layer is connected to the corresponding relay through a power line. A flexible transparent power line is connected to the electrode film on the inner ring of the conductive electrode layer. The flexible transparent power line is laid along the insulating groove and is connected to the corresponding relay on the wiring frame.

[0009] Furthermore, the window frame includes multiple frames, which are connected sequentially to form a frame structure. Both sides of the inner side of each frame are provided with glass mounting grooves that can be engaged and positioned with the glass. The inner side of the frame is also provided with an electrochromic film mounting groove that can position and install the electrochromic film.

[0010] Furthermore, the inner ring of the frame is provided with a wiring groove for positioning and installing the wiring rack.

[0011] Furthermore, the outer side of the wiring trough is provided with an opening, and both sides of the opening are provided with sliding grooves. A sealing plate that can seal the opening is slidably installed in the sliding groove, and the sealing plate is also locked and fixed to the frame by screws.

[0012] Furthermore, a temperature-regulating through hole communicating with the wiring groove is provided on the side of the frame facing the interior.

[0013] Furthermore, an insulated chamber located outside the wiring trough is provided on the outdoor side of the frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, an electrochromic film composed of a conductive electrode layer, an electrochromic layer, an electrolyte layer, and an ion storage layer is installed on the inner side of the window glass. The conductive electrode layers on both sides apply current and pressure to the electrochromic layer, electrolyte layer, and ion storage layer in the middle, so that ions can migrate between the electrochromic layer and the ion storage layer through the electrolyte layer. This allows the electrochromic layer to switch between transparent and colored states, so that the window glass can both transmit light and be converted into colored states when needed to block light and external views, without the need for curtains to block light and views, thus improving the convenience and aesthetics of the window.

[0016] 2. In this utility model, the voltage between the two conductive electrode layers can be adjusted by a voltage regulator. When the voltage is higher, the electrochromic layer is darker and the light-blocking effect is better, thus reducing the light transmittance of the window. Conversely, when the voltage is lower, the electrochromic layer is lighter and the light-blocking effect is poor, thus increasing the light transmittance of the window. Therefore, the light passing through the window can be adjusted by voltage regulation to keep the indoor light at a suitable brightness and prevent excessive light from causing indoor light pollution.

[0017] 3. In this utility model, each conductive electrode layer is composed of multiple electrode films, and the multiple electrode films in two conductive electrode layers are arranged in a one-to-one correspondence. Each electrode film is connected to an independent power line. By setting multiple electrode films, the electrochromic layer can be controlled in zones to control the light transmittance of different positions of the window, so as to meet different usage needs and improve the applicability of the window.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements 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 the utility model.

[0027] Please see Figures 1-4As shown, this utility model is a light-adjusting window based on electrochromic properties, including a window frame 1. Glass 2 is fixedly installed on both sides of the inner circle of the window frame 1. An electrochromic film is also installed between the glass 2 on both sides of the inner circle of the window frame 1. The electrochromic film includes conductive electrode layers 3 respectively disposed on the inner side of the two glass 2. An electrochromic layer 4, an electrolyte layer 5 and an ion storage layer 6 are sequentially and tightly disposed between the two conductive electrode layers 3. Each of the two conductive electrode layers 3 is composed of multiple electrode films 31, and the multiple electrode films 31 in the two conductive electrode layers 3 are arranged one-to-one. Each electrode film 31 is connected to an independent power line, and the power line is connected to the power supply through a voltage regulator and a relay.

[0028] When adjusting the light, the conductive electrode layers 3 on both sides are connected to the power supply via power lines, voltage regulators, relays, and power sources. This allows the conductive electrode layers 3 on both sides to apply current and pressure to the electrochromic layer 4, electrolyte layer 5, and ion storage layer 6 in the middle. This enables ions to migrate between the electrochromic layer 4 and the ion storage layer 6 via the electrolyte layer 5. Through ion migration, the electrochromic layer 4 can switch between transparent and colored states. This allows the window glass to both transmit light and, when needed, switch to colored states to block light and obstruct the view from the outside, eliminating the need for curtains to block light and obstruct the view, thus improving the convenience and aesthetics of the window.

[0029] Taking the example of using a nickel oxide layer for the ion storage layer 6 and a tungsten trioxide layer for the electrochromic layer 4, when a positive voltage is applied to the conductive electrode layers 3 on both sides, the ion storage layer 6 releases cations. The cations migrate through the electrolyte layer 5 to the electrochromic layer 4, where a reduction reaction occurs, generating blue tungsten bronze. The glass darkens, and the light transmittance of the window decreases. When a reverse voltage is applied, the ions return to the ion storage layer 6, and the electrochromic layer 4 undergoes an oxidation reaction, restoring the transparent state.

[0030] The voltage between the two conductive electrode layers 3 can be adjusted by a voltage regulator. When the voltage is higher, the electrochromic layer 4 is darker and the light-blocking effect is better, which reduces the light transmittance of the window. Conversely, when the voltage is lower, the electrochromic layer 4 is lighter and the light-blocking effect is poor, which increases the light transmittance of the window. Thus, the light passing through the window can be adjusted by voltage regulation to keep the indoor light at a suitable brightness and prevent excessive light from causing indoor light pollution.

[0031] Furthermore, the light-adjusting window also includes an intelligent controller and light sensors installed on the inside and outside of the window respectively. The light sensors can detect the intensity of indoor and outdoor light, and the light sensors are connected to the intelligent controller via signal. The intelligent controller is connected to the voltage regulator and relay for electronic control. Thus, through the cooperation of the intelligent controller, light sensors, voltage regulator and relay, the light transmittance of the window can be intelligently adjusted, thereby adjusting the intensity of indoor light.

[0032] By setting multiple electrode films 31 and energizing two corresponding electrode films 31, the color depth of the electrochromic layer 4 at corresponding positions can be adjusted, thereby enabling zoned control of the electrochromic layer 4 to control the light transmittance at different positions of the window, meet different usage needs, and improve the applicability of the window.

[0033] Specifically, an insulating groove 32 is provided between adjacent electrode films 31. The interior of the insulating groove 32 is filled with transparent insulating glue. By providing the insulating groove 32 and the transparent insulating glue, the insulation between adjacent electrode films 31 can be improved, preventing the electrode films 31 from interfering with each other. The insulating groove 32 is a fine groove of 0.5–3 mm, and the insulating groove 32 is filled with transparent insulating glue (epoxy resin) to reduce the impact of the insulating groove 32 on the light transmittance of the window.

[0034] Specifically, a wiring frame 33 is provided on the outer ring of the conductive electrode layer 3. Relays and voltage regulators corresponding to the electrode film 31 are fixedly installed on the wiring frame 33. The electrode film 31 on the outer ring of the conductive electrode layer 3 is connected to the corresponding relays and voltage regulators through power lines. Flexible transparent power lines are connected to the electrode film 31 on the inner ring of the conductive electrode layer 3. The flexible transparent power lines are laid along the insulating groove 32 and are connected to the corresponding relays and voltage regulators on the wiring frame 33. The flexible transparent power lines are made of silver nanowires. The electrical connection of the inner ring electrode film 31 through the flexible transparent power lines can prevent the layout of the power lines from affecting the light transmission performance of the window. The wiring frame 33 is used to lay out and install the relays, voltage regulators and power lines, making the installation and layout of the control circuit more convenient.

[0035] Specifically, the window frame 1 includes multiple frames 11, which are connected sequentially to form a frame structure. Both sides of the inner side of the frame 11 are provided with glass mounting grooves 13 that can be engaged and positioned with the glass 2. The inner side of the frame 11 is also provided with an electrochromic film mounting groove 14 that can position and install the electrochromic film. The glass 2 and the electrochromic film can be stably installed through the glass mounting grooves 13 and the electrochromic film mounting grooves 14, respectively.

[0036] Specifically, the inner ring of the frame 11 is provided with a wiring groove 12 for positioning and installing the wiring frame 33. The wiring frame 33 is installed in a concealed manner inside the window frame 1 through the wiring groove 12, which can protect and hide the wiring frame 33 and its control circuit, thereby improving the safety and aesthetics of the window.

[0037] Specifically, the outer side of the wiring trough 12 is provided with an opening, and both sides of the opening are provided with sliding grooves 17. A sealing plate 16 that can seal the opening is slidably installed in the sliding groove 17. The sealing plate 16 is also locked and fixed to the frame 11 by screws. The sealing plate 16 can isolate and protect the wiring rack 33 and its control circuit in the wiring trough 12. When the control circuit needs to be inspected or replaced, the screws can be loosened and the sealing plate 16 can be slid out to facilitate the inspection and replacement of the control circuit in the wiring trough 12.

[0038] Specifically, a temperature regulating through hole 15 is provided on the side of the frame 11 facing the room, which is connected to the wiring trough 12. When the temperature is high in summer or low in winter, if the air conditioner is turned on to regulate the temperature, the indoor airflow can enter the wiring trough 12 through the temperature regulating through hole 15 to regulate the temperature of the control circuit in the wiring trough 12, so as to prevent the temperature from being too high or too low and affecting the normal operation of the control circuit.

[0039] Specifically, a heat-insulating chamber 18 is provided on the side of the frame 11 facing the outside, located outside the wiring trough 12. The heat-insulating chamber 18 can insulate the wiring trough 12 and prevent the outside temperature from being transmitted into the wiring trough 12 and affecting the normal operation of the control circuit inside the wiring trough 12.
