Description

Technical Field

[0001] The present invention relates to the field of blinds, and in particular to a phase-changing temperature-controlled blind. Background Art

[0002] In modern architecture, windows are essential components for energy exchange, light regulation, and ventilation between buildings and the outside world. Optimizing their performance has always been a key area of ​​architectural technology development. Traditional windows have limitations in regulating indoor light and protecting privacy, often requiring the installation of additional shading devices such as curtains and blinds to achieve these functions. However, these external shading devices not only increase building renovation costs but also occupy interior space, affecting the overall aesthetics of the interior. They are also prone to dust accumulation and damage during daily use, making them difficult to clean and maintain.

[0003] Built-in blinds effectively address these issues. These blinds integrate directly between double or multiple layers of glass, creating a unique window structure. This design seamlessly integrates the blinds with the glass, eliminating the need for additional interior space while blending seamlessly with the building's exterior, enhancing the overall aesthetics.

[0004] From a functional perspective, built-in blinds offer flexible light adjustment capabilities. Users can easily adjust the angle of the blinds' blades using control devices (such as manual knobs or electric control buttons) based on their actual needs, thereby precisely controlling the intensity and direction of light entering the room and meeting lighting requirements in different scenarios. Furthermore, when privacy is required, simply closing the blinds completely effectively blocks outside view, providing a private space for those inside. While traditional hollow louvers can moderate light and provide insulation to a certain extent, they still have significant room for improvement in terms of energy efficiency. In summer, high temperatures easily enter through windows, increasing energy consumption for air conditioners and other cooling equipment. In winter, heat easily escapes through windows, increasing energy consumption for heating equipment. Summary of the Invention

[0005] In order to reduce the impact of external temperature on indoor temperature, reduce the use of refrigeration equipment and heating equipment, and reduce energy consumption, the present invention provides a phase-changing temperature-controlled blinds.

[0007] By adopting this technical solution, cavities are created within the louver blades and filled with phase-change material.

[0017] By adopting the above technical solution, the movable base is provided with a mounting groove and a pressure plate, and the locking bolt is used to press the pressure plate to firmly fix the handle to the movable base. This design not only facilitates the installation and removal of the handle, but also ensures the stability of the handle during movement, improving the safety and durability of the product.

[0018] Optionally, a cover plate is hinged on the mounting frame and can be detachably arranged on the mounting frame. A rotating shaft is connected inside the mounting frame. The central axis of the rotating shaft is colinear with the rotating axis of the cover plate, and the axial direction of the rotating shaft is parallel to the moving direction of the handle.

[0036] The following is combined with Figure 1-9 The present invention is described in further detail.

[0037] Example 1 The embodiment of the present invention discloses a phase-changing temperature-controlled blind. Figure 1 and Figure 2 The phase-change temperature-controlled blinds include a frame 1, which serves as a supporting structure for the entire blind 12 sash. Glass plates 11 are provided on both sides thereof, and blinds 12 are provided in the space between the two glass plates 11. A transmission device for controlling the retraction and extension of the blinds 12 is provided in the frame 1.

[0038] like Figure 2 and Figure 3The blades 13 of the louver 12 are internally provided with a cavity 14 filled with a phase change material. The phase change material is PCM or paraffin wax. Both materials have excellent thermal stability and heat capacity, capable of absorbing or releasing large amounts of heat during temperature changes. In this embodiment, the phase change material is a bio-based PCM (such as ethyl palmitate). Ethyl palmitate is a typical bio-based phase change material (PCM) that stores and releases thermal energy through a reversible solid-liquid phase transition. When the ambient temperature exceeds its melting point (30-32°C, depending on purity), ethyl palmitate melts from a solid to a liquid state, absorbing a large amount of latent heat (180-220 J / g), which prevents further increases in the indoor temperature. When the ambient temperature falls below its freezing point (28-30°C), the liquid ethyl palmitate resolidifies, releasing the stored heat and slowing the drop in indoor temperature.

[0039] Of course, the choice of phase change material is determined according to the conditions of the climate zone. Table 1 lists several phase change materials that can be used in different climate zones.

[0040] Table 1

[0041] A temperature sensor is also provided between the two glass plates 11 for detecting the temperature at the window. When the temperature is detected to be too high, the blinds can be opened. When the blinds are opened, when the external ambient temperature rises and is higher than the phase change temperature of the phase change material, the phase change material melts and absorbs heat, effectively reducing the rate of increase of the indoor temperature; when the temperature drops and is lower than the second preset temperature, the phase change material solidifies and releases heat, playing a certain role in heat preservation, thereby realizing the regulation of the indoor temperature and achieving energy-saving effects.

[0042] In addition, to further improve the energy-saving performance of the blinds 12, a heat-reflective coating is provided on the surface of the blades 13. This coating can reflect some of the solar radiation heat, reducing the heat entering the room, thereby reducing the energy consumption of refrigeration equipment such as air conditioners.

[0043] Example 2 like Figure 4 and Figure 5 The remaining components of this embodiment of the present invention are identical to those of Example 1, differing in that a handle 15 is typically provided on the exterior of the glass panel. This handle 15, through magnets, engages a transmission mechanism within the frame 1 to retract and extend the blinds 12. When the blinds 12 are positioned vertically, the operator vertically moves the handle 15, which, in turn, rotates the transmission mechanism to lower or raise the blinds 12. A drive mechanism 2 is also provided on the exterior of the glass panel 11, controlling the raising and lowering of the handle 15, thus reducing the inconvenience of manually moving the handle 15.

[0044] like Figure 6 and Figure 7The driving device 2 includes a mounting frame 21 mounted on the glass plate 11. The mounting frame 21 is hinged with a cover plate 22, and the free end of the cover plate 22 is detachably mounted on the mounting frame 21 by screws. A rotating shaft 24 is connected to the mounting frame 21, and the central axis of the rotating shaft 24 is colinear with the rotation axis of the mounting frame 21. The axial direction of the rotating shaft 24 is parallel to the moving direction of the handle 15. A sliding seat 25 is provided on the rotating shaft 24, and the sliding seat 25 is rotatably mounted on the rotating shaft 24. The sliding seat 25 is fixedly connected to the moving seat 3, and the handle 15 is detachably mounted on the moving seat 3. A crank 26 is rotatably connected to the sliding seat 25. A driving assembly 4 for driving the crank 26 to move is provided on the mounting frame 21. The crank 26 and the moving seat 3 are driven up and down by the driving assembly 4, thereby realizing the lifting and lowering control of the handle 15.

[0045] like Figure 8 The movable base 3 is provided with a mounting groove 31 for accommodating the handle 15. A pressure plate 32 is movably provided in the movable base 3, and the pressure plate 32 is always arranged opposite to one of the inner walls of the mounting groove 31. In the embodiment of the present invention, a first connecting rod 33 and a second connecting rod 34 are hinged to the pressure plate 32. The ends of the first connecting rod 33 and the second connecting rod 34 away from the pressure plate 32 are both hinged to the groove wall of the mounting groove 31. The spacing between the hinge axes at both ends of the first connecting rod 33 is the same as the spacing between the hinge axes at both ends of the second connecting rod 34, and the first connecting rod 33 is parallel to the second connecting rod 34, so as to ensure that the pressure plate 32 remains opposite to the corresponding inner wall of the mounting groove 31 during the flipping process. A locking bolt 35 is threadedly connected to the movable seat 3. The locking bolt 35 passes through the groove wall of the corresponding mounting groove 31 and is used to push the pressure plate 32. The operator sets the handle 15 in the mounting groove 31. The operator tightens the locking bolt 35 so that the locking bolt 35 pushes the pressure plate 32, so that the pressure plate 32 presses the handle 15 against the inner wall of the mounting groove 31, thereby realizing the detachable fixation of the handle 15 and the movable seat 3 and ensuring the installation stability of the handle 15 in the mounting groove 31.

[0046] like Figure 6 、 Figure 7 as well as Figure 9 The drive assembly 4 includes a first synchronous wheel 41 and a second synchronous wheel 42 rotatably connected to the cover plate 22. The first synchronous wheel 41 is disposed at one end of the cover plate 22, and the second synchronous wheel 42 is disposed at the other end of the cover plate 22. A synchronous belt 43 is wound between the first synchronous wheel 41 and the second synchronous wheel 42, and the crank 26 is fixedly connected to the synchronous belt 43 by bolts. A drive unit 5 for controlling the rotation of the first synchronous wheel 41 is disposed on the mounting frame 21. The drive unit 5 drives the first synchronous wheel 41 to rotate, and the rotation of the first synchronous wheel 41 drives the belt 53 to move, thereby driving the crank 26, the movable base 3, and the handle 15 to synchronously raise and lower the crank 26, the movable base 3, and the handle 15, thereby facilitating the operator's control of the retraction and extension of the blinds 12.

[0047] Specifically, the drive unit 5 includes a driving pulley 51 and a driven pulley 52 that are rotatably connected to the mounting frame 21, and the driving pulley 51 and the driven pulley 52 are driven by a belt 53. The mounting frame 21 is fixedly connected to a drive motor 54 for driving the driving pulley 51 to rotate, and the driven pulley 52 is connected to the first synchronous wheel 41 for transmission. A first spline hole 61 is coaxially provided on the first synchronous wheel 41, and a spline shaft 6 is slidably inserted into the first spline hole 61. A second spline hole 62 that can cooperate with the spline shaft 6 is coaxially provided on the driven pulley 52. ​​The operator controls the transmission engagement or disengagement between the spline shaft 6 and the second spline hole 62 by moving the position of the spline shaft 6 in the first spline hole 61. A stud 65 is rotatably connected to the end of the spline shaft 6 away from the second spline hole 62, and the first synchronous wheel 41 is provided with a screw barrel 66 for cooperating with the stud 65. By controlling the driven pulley 52 to be connected to the first synchronous wheel 41 or disconnecting the transmission connection in this way, the operator can open the cover 22 to inspect the internal structure and the handle 15 can be easily assembled and disassembled with the movable seat 3.

[0048] The operator starts the drive motor 54 to drive the active pulley 51 to rotate, and the driven pulley 52 is driven to rotate under the transmission action of the belt 53, and the first synchronous wheel 41 is driven to rotate under the cooperation of the spline shaft 6 and the first spline hole 61 and the second spline hole 62, and then the synchronous belt 43 is driven to move, thereby achieving the effect of controlling the movement of the handle 15, making it convenient for the operator to control the retraction and extension of the blinds 12.

[0049] Example 3 This embodiment is otherwise identical to Embodiment 2, differing in that it further includes a main control unit, which is connected to a drive motor 54 and a temperature sensor. The main control unit can be used to set the temperature at which the blinds automatically open. When the temperature exceeds the set temperature, the main control unit sends a signal to the drive motor 54, which activates the drive motor 54 and drives the blinds down, absorbing heat through phase change. Similarly, when the temperature falls below the set temperature, the main control unit sends a signal to the drive motor 54, which activates the drive motor 54 and drives the blinds down, releasing heat through phase change, heating the window and thus saving energy.

[0050] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
