Description

Technical Field

[0001] This invention relates to the field of curtain wall ventilation technology, specifically a double-layer energy-saving curtain wall ventilation structure. Background Technology

[0002] Double-layer curtain walls, also known as thermal aisle curtain walls, breathing curtain walls, ventilated curtain walls, and energy-saving curtain walls, consist of two facade layers, forming an air buffer between the interior and exterior. They have air inlets at the bottom and exhaust vents at the top, allowing for controlled airflow. With scientific advancements and rising living standards, the requirements for curtain walls in modern buildings are increasingly stringent, with ventilation and heat transfer properties receiving greater attention.

[0003] However, during the use or installation of double-layer curtain walls, the internal ventilation effect is currently poor. If the internal airflow relies solely on natural wind for ventilation, it cannot effectively handle the heat generated by the double-layer curtain wall. As a result, the internal space heat gradually increases with solar radiation. This is because traditional technical solutions only provide a single ventilation duct between the inner and outer curtain walls. If the natural airflow is weak, the airflow between the inner and outer curtain walls cannot quickly exchange and achieve cooling. Consequently, as the temperature rises, the lifespan of the curtain wall is reduced. Furthermore, the weak airflow between the inner and outer curtain walls also allows heat to radiate into the room through the inner curtain wall, causing the indoor temperature to rise. Therefore, a double-layer energy-saving curtain wall ventilation structure is proposed to solve the above-mentioned problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a double-layer energy-saving curtain wall ventilation structure, which has the following characteristics:

[0018] Beneficial effects:

[0019] 1. This double-layer energy-saving curtain wall ventilation structure, through its ventilation components, can actively propel the air between the inner and outer curtain walls, achieving rapid airflow replacement. Therefore, during the hottest periods in summer, the active operation of the ventilation components can be controlled to propel the airflow, ensuring rapid internal airflow, cooling the double-layer curtain wall, extending its service life, and lowering the indoor ambient temperature. Compared to traditional natural airflow, this active propulsion method can propel the airflow more quickly, resulting in better ventilation. In winter, the operation of the ventilation components can be directly shut off, reducing the flow of internal hot air and radiating heat into the room, thus improving indoor comfort.

[0020] 2. The ventilation structure of this double-layer energy-saving curtain wall can absorb and discharge external airflow through the set air duct components, so that the curtain wall can create a "breathing channel" through which airflow can flow naturally, ensuring natural ventilation of the curtain wall. Furthermore, the air duct components can be opened and closed autonomously by the adjustment device, so the operator can adjust the opening degree of the air duct components according to the ambient temperature of the curtain wall or the room.

[0021] 3. This double-layer energy-saving curtain wall ventilation structure, through the installation of cleaning components, enables the cleaning components to clean the surfaces of both the inner and outer curtain walls when the ventilation components are running, thereby directly avoiding the difficult process of cleaning the curtain wall and making it more convenient to use.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-7 A double-layer energy-saving curtain wall ventilation structure includes an upper wall 1 and a lower wall 2. Connectors 3 are installed on the upper wall 1 and the lower wall 2, and an outer curtain wall 4 and an inner curtain wall 7 are installed on the connectors 3. A flow air chamber is provided between the inner curtain wall 7 and the outer curtain wall 4. Air duct assemblies 5 for air intake are also provided on the upper wall 1 and the lower wall 2. Ventilation components 6 are provided on the upper wall 1 and the lower wall 2 to actively push the airflow in the flow air chamber. The ventilation components 6 include a power component, a moving component, and a cleaning component. The power component drives the moving component to circulate, thereby accelerating the airflow in the flow air chamber, and simultaneously controls the cleaning component to automatically clean the surface deposits of the inner curtain wall 7 and the outer curtain wall 4.

[0032] In this embodiment, the connector 3 includes an upper connecting frame 301 and a lower connecting frame 302. The upper connecting frame 301 is fixed to the upper wall 1 by bolts, and the lower connecting frame 302 is fixed to the lower wall 2 by bolts. Both the upper connecting frame 301 and the lower connecting frame 302 have mounting slots, and the outer curtain wall 4 is connected to the upper connecting frame 301 and the lower connecting frame 302 through these mounting slots. A base bracket 303 is also installed on the lower wall 2, and the inner curtain wall 7 is installed on the base bracket 303. The upper connecting frame 301 and the lower connecting frame 302 provide installation space for the outer curtain wall 4, enabling media installation. Different specifications of curtain walls can be installed using different types of upper connecting frames 301 and lower connecting frames 302.

[0033] Furthermore, the duct assembly 5 includes a vertical duct 501, on which multiple louvers 503 are rotatably connected. Side air channels 502 are provided on both sides of the vertical duct 501, located inside the airflow chamber. An adjustment device is installed inside the vertical duct 501. The vertical duct 501 enables communication between the airflow chamber and the outside environment, providing a spatial channel for airflow. Outside air enters the vertical duct 501 through the channels of the louvers 503, and then enters the airflow chamber from the side air channels 502. The airflow chamber and the multiple vertical ducts 501 are also interconnected, ensuring a continuous airflow.

[0034] Furthermore, the adjusting device includes an adjusting rod 505, a rotating sleeve 507 connected to the right end of the adjusting rod 505, a threaded sleeve 506 threadedly connected to the surface of the adjusting rod 505, a support rod 508 rotatably connected to the threaded sleeve 506, a connecting plate 509 rotatably connected to the top of the support rod 508, a sliding rack 510 connected to the connecting plate 509, and pinions 511 fixedly connected to both sides of the louvers 503. The surface of the sliding rack 510 is provided with teeth, and the teeth mesh with the pinions 511. The threaded sleeve 506 of the threaded connection is moved back and forth by rotating the adjusting rod 505. When moving forward, the support rod 508 of the triangular connection will rotate, which will drive the connecting plate 509 to move upward, and then drive the sliding rack 510 to move upward. The sliding rack 510 will drive the teeth to mesh with multiple pinions 511 and rotate. The rotation of the pinions 511 will drive multiple louvers 503 to rotate, so the louvers 503 will be in an open state. Therefore, the operator can directly control the size of the opening of the external air duct assembly 5 according to the rotation of the adjusting rod 505 to change the ventilation volume.

[0035] In addition, multiple duct assemblies 5 are provided, and the outer curtain wall 4 is located between two duct assemblies 5. Vertical partitions 504 are provided inside the vertical ducts 501, and spacers 512 are rotatably connected to the adjusting rods 505. The spacers 512 are located between two inner curtain walls 7. The spacers 512 provide installation intervals for the inner curtain walls 7, and by using the spacers 512, the airflow cavity can be divided into multiple small spaces of the same size. Because the air is divided in small spaces, the mutual transfer of heat is reduced, avoiding overall overheating of the airflow cavity and resulting in thermal expansion damage to the curtain wall. The spacers 512 will correspondingly divide the heat, so even if overheating occurs, it will only occur in a small space, not the entire process, thus protecting the curtain wall.

[0036] In addition, the moving parts include a power crank 601, one end of which is rotatably connected to the upper wall 1, and the other end of which is connected to a drive component installed inside the lower wall 2. A push rod 602 is rotatably connected to the power crank 601, and a pusher plate 603 is rotatably connected to the right end of the push rod 602. The pusher plate 603 is slidably connected inside the airflow chamber. The drive component controls the rotation of the power crank 601, which in turn pulls the push rod 602 in a left-right cyclical motion. At this time, the pusher plate 603 will realize a reciprocating cyclical motion, which then drives the airflow inside the airflow chamber to move rapidly to the left, similar to an "exhaust mechanism". By using the pusher plate 603 to push the overall airflow in the airflow chamber, the overall ventilation effect of the curtain wall is improved.

[0037] It is worth noting that multiple pusher plates 603 are provided, and all multiple pusher plates 603 are located inside the flow air chamber. The multiple pusher plates 603 are connected by a connecting rack 606. The connecting rack 606 is slidably connected to the spacer 512. The connecting rack 606 is located inside the spacer 512 and meshes with an automatic gear 607. The automatic gear 607 is mounted on the adjusting rod 505. Two vents are provided on the pusher plate 603. A guide rod 605 is slidably connected to the pusher plate 603. One end of the guide rod 605 is connected to a sealing plate 604, which covers the vents. An air groove 608 is provided on the spacer 512. Multiple pusher plates 603 are provided, and the synchronous pushing of multiple pusher plates 603 is achieved by connecting the connecting toothed rods 606. Under the push of multiple pusher plates 603, the airflow between the pusher plates 603 and the spacer 512 will be discharged from the opening of the duct assembly 5. Because the multiple pusher plates 603 will form a similar "closed area", the airflow will enter the right side air groove 502 of the second vertical duct 501. Because the vertical duct 501 is equipped with a vertical partition 504, it divides the interior into two spaces on the left and right sides. The airflow will be pushed from the side air groove 502 into the interior of the vertical duct 501 and discharged externally. Furthermore, under the push of the propulsion plate 603, the connecting gear 606 will move laterally. Then, through the meshing of the teeth, the automatic gear 607 will rotate. The rotation of the automatic gear 607 will drive the rotation of the adjusting rod 505, thereby automatically controlling the opening size of the air duct assembly 5. This will enable the opening of the vertical air duct 501 to become larger during exhaust, increasing the volume of hot air. During intake, it will reduce the repeated absorption of exhaust gas and avoid repeated heat absorption.

[0038] It is worth noting that the cleaning component includes a core rod 609, which is installed inside the push plate 603. A coil 610 is wound around the surface of the core rod 609. A power module is installed inside the upper wall 1 or the lower wall 2. The coil 610 is electrically connected to the power module. A magnetic sheet 611 is connected to one end of the core rod 609. A magnetic suction sheet 613 is magnetically connected to one side of the magnetic sheet 611. A hook 614 is installed on the magnetic suction sheet 613. The hook 614 is slidably connected to the connector 3. A cleaning frame 612 is installed on the hook 614. The cleaning frame 612 abuts against the surface of the outer curtain wall 4. An inner frame 615 is installed on the push plate 603. The surface of the inner frame 615 abuts against the surface of the inner curtain wall 7. Considering that dust adhering to the surface of the double-layer curtain wall is difficult to clean after installation, a cleaning component is provided. When the power button of the power module is pressed, the core rod 609 is magnetized by the winding of the coil 610. Then, the magnetic force will be transmitted to the magnetic sheet 611, and the magnetic sheet 611 and the magnetic suction sheet 613 will be magnetically attracted. Then, with the reciprocating motion of the pusher plate 603, the hook 614 and the cleaning frame 612 on the magnetic suction sheet 613 will move synchronously through the principle of electromagnetism. Furthermore, the inner frame 615 is connected to the internal air chamber on the pusher plate 603. Therefore, with the movement of the pusher plate 603, the cleaning frame 612 and the inner frame 615 will scrape the dust off the surface of the outer curtain wall 4 and the inner curtain wall 7, realizing automatic curtain wall cleaning.

[0039] Working principle: First, when the entire curtain wall is in use, sunlight shining on the outer curtain wall 4 will heat the air inside the airflow chamber. The airflow chamber is located between the outer curtain wall 4 and the inner curtain wall 7, so the heat will radiate to the indoor space through the inner curtain wall 7. Therefore, the indoor temperature will also be affected by the air temperature in the airflow chamber. If the indoor temperature is high, the threaded sleeve 506 of the threaded connection can be moved back and forth by rotating the adjusting rod 505. When moving forward, the support rod 508 of the triangular connection will rotate, thereby driving the connecting plate 509 to move upward, which in turn drives the sliding rack 510 to move upward. The sliding rack 510 will drive the teeth to mesh with multiple pinions 511 and rotate. The rotation of the pinions 511 will drive multiple louvers 503 to rotate, so the louvers 503 will be in an open state. If the threaded sleeve 506 rotates in the opposite direction, the sliding rack 510 will be moved downward by gravity, thereby driving the pinions 511 to rotate in the opposite direction, thereby driving the louvers 503 to close. Therefore, the operator can directly control the size of the opening of the external duct assembly 5 by rotating the adjusting rod 505, thereby changing the ventilation volume. During the hot summer months, it is essential to ensure high airflow in the air chamber; otherwise, the continuous sunlight heating the air inside the air chamber will cause the temperature of the radiant air entering the room to rise. Therefore, the rotation of the driving component is directly controlled. This driving component is an electric component, such as a motor, or any component that controls the rotation of the power crank 601. The rotation of the power crank 601 will pull the push rod 602 in a left-right cyclical motion, which in turn drives the pusher plate 603 in a left-right cyclical motion. When the pusher plate 603 moves to the left (…), Figure 1 From the perspective of the entire enclosed plate structure, the airflow inside the flow chamber will move rapidly to the left. Then, if the pusher plate 603 moves to the right (…), Figure 1From the perspective of the airflow, due to inertia, the control rod 605 slides on the pusher plate 603, thereby causing the sealing plate 604 to move away from the pusher plate 603, creating a gap. At this time, the airflow on the right side will flow into the left side of the pusher plate 603 from the opening slot. When the pusher plate 603 moves to the left again, it will first push the pusher plate 603. Then, due to inertia and the compression of the air in front, the control sealing plate 604 will abut against the opening slot, forming the pusher plate 603 into a closed plate, maximizing the control of the airflow. At this time, the airflow will pass through the air slot 608 opened on the partition 512 and enter another section of the flow air chamber. This process repeats until the airflow is finally transmitted to the interior of the leftmost air duct assembly 5, realizing the airflow discharge. Therefore, the overall principle is similar to "piston motion". When the airflow enters through the vertical duct 501, it will enter the flow chamber through the opening of the side air duct 502. Then, with the movement of the "piston", the flow of the flow chamber is improved, thereby ensuring the overall ventilation effect of the curtain wall and the radiation control of indoor temperature by operators in different environments. Multiple pusher plates 603 are set, and the connection of the connecting toothed rod 606 is used to realize the synchronous push of multiple pusher plates 603. Under the push of multiple pusher plates 603, the airflow between the pusher plates 603 and the spacer 512 will be discharged from the opening of the duct assembly 5. Because the multiple pusher plates 603 will form a similar "closed area", the airflow will enter the right side air duct 502 of the second vertical duct 501. Because the vertical duct 501 is equipped with a vertical partition 504, it divides the interior into two spaces, left and right. The push of the airflow will enter the interior of the vertical duct 501 from the side air duct 502 and be discharged. Furthermore, driven by the pusher plate 603, the connecting gear 606 will move laterally. Then, through the meshing of the teeth, the automatic gear 607 will rotate. The rotation of the automatic gear 607 will then drive the adjusting rod 505, thereby automatically controlling the opening size of the duct assembly 5. This ensures that during exhaust, the opening of the vertical duct 501 increases, increasing the volume of hot air. During intake, it reduces the repeated absorption of exhaust gas because the automatic gear 607 rotates in the opposite direction, controlling the opening of the vertical duct 501, i.e., the opening of the louver 503, to decrease. Therefore, during intake, the ventilation assembly 6 reduces the hot airflow just exhausted from the outside, achieving efficient self-exhaust of the airflow chamber and ventilation and cooling of the curtain wall. Alternatively, the entire solution can use a single pusher plate 603 to achieve overall airflow exhaust of the airflow chamber; the actual solution can be selected based on the user's choice.Considering the difficulty in cleaning dust adhering to the surface of double-layer curtain walls after installation, a cleaning mechanism is installed. This mechanism utilizes the principle of electromagnetism. Traditional magnetic strips demagnetize over time, so electromagnetism generates magnetic force when electricity is applied. When the power module's power-on button is pressed, the coil 610 magnetizes the core rod 609. The magnetic force is then transferred to the magnetic sheet 611, causing magnetic attraction between the magnetic sheet 611 and the magnetic attractor 613. Subsequently, the reciprocating motion of the pusher plate 603, through the principle of electromagnetism, drives the magnetic... The hook 614 and cleaning frame 612 on the suction plate 613 move synchronously, and the inner frame 615 is connected inside the airflow chamber on the push plate 603. Therefore, as the push plate 603 moves, it will drive the cleaning frame 612 and the inner frame 615 to scrape the dust off the surface of the outer curtain wall 4 and the inner curtain wall 7. Since the airflow chamber is filled with air from the outside, the surface of the outer curtain wall 4 and the inner curtain wall 7 will inevitably accumulate dust after long-term use, which is not easy to clean. Therefore, the magnetic attraction is used to achieve a selectable cleaning operation, which is simple, convenient and fast.
