Description

Technical Field

[0001] This invention relates to the field of curtain wall ventilation equipment technology, and in particular to a curtain wall ventilator and a curtain wall ventilation system including the curtain wall ventilator. Background Technology

[0002] As an external building envelope, the curtain wall must simultaneously meet the requirements of water tightness, air tightness, and thermal insulation, as well as the functional requirements of indoor ventilation. Traditional ventilation solutions (such as window ventilation and external ventilators) have significant drawbacks: window ventilation has poor safety and is prone to sealing failure; external ventilators can damage the overall appearance of the curtain wall, are complex to install, and are mostly manually controlled with low levels of automation. Therefore, integrating ventilation systems within the curtain wall frame, such as columns and beams, has become a technological development direction, aiming to balance building envelope performance and ventilation functionality. However, existing integrated solutions still face key technological bottlenecks.

[0003] Existing integrated solutions primarily involve integrating air ducts within the profile's internal space, attempting to achieve ventilation using unidirectional fans (supporting only a single ventilation mode of supply or exhaust air) without compromising the curtain wall's appearance. Theoretically, this relies on the physical barrier created when the dampers are closed to ensure the curtain wall's sealing performance. However, this integrated solution has the following shortcomings:

[0004] (1) Limitations of fan function and size: The fan operates in one direction and does not have the ability to flexibly switch between air supply and exhaust modes; and because the fan is too large, the curtain wall profiles need to be widened and thickened, which increases material costs and installation difficulty, and may even affect the mechanical stability of the curtain wall.

[0005] (2) Unreasonable integrated layout: The layout of air ducts, fans and dampers in the profile is not integrated, and complex processing of the profile is required during installation (such as drilling and reinforcement), which makes assembly difficult;

[0006] (3) Insufficient sealing performance: Since the air duct is sealed by relying solely on the damper, and the conventional damper has a relatively simple sealing structure design, such as using simple rubber strip overlap, the sealing pressure and durability of dynamic opening and closing are not considered; in addition, the fit between the damper and the air duct is low, and the resulting gaps will lead to sealing failure; therefore, when the damper is closed, the water tightness, air tightness and thermal insulation are difficult to meet the curtain wall standards (such as GB / T 21086 "Building Curtain Wall"), and the phenomena of air leakage, water leakage and heat loss are prominent. Summary of the Invention

[0007] The purpose of this invention is to provide a curtain wall ventilator and a curtain wall ventilation system incorporating the ventilator. It adopts a modular design approach, using a box-like structure adaptable to curtain wall installation. This integrated box incorporates ventilation channels, a fan, and damper components, facilitating installation within the curtain wall frame space, simplifying installation, reducing maintenance costs, and ensuring the mechanical stability of the curtain wall. Simultaneously, the fan can operate in both directions, supporting bidirectional ventilation and offering both supply and exhaust modes. Furthermore, baffles and damper components seal the ventilation channels from both indoor and outdoor sides, utilizing a double-door sealing design to balance sealing performance and ventilation flexibility. This invention solves the problems of existing curtain wall ventilation structures, such as unidirectional ventilation, insufficient sealing performance, and unreasonable overall integrated layout.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] In a first aspect, the present invention provides a curtain wall ventilator, comprising a housing adapted for curtain wall installation and a control device disposed on the housing. The housing has a ventilation channel extending through both ends of the housing. One end of the ventilation channel is provided with a fan capable of rotating in both directions for air intake or exhaust. The other end of the ventilation channel is provided with a damper assembly. The damper assembly is connected to a drive device for driving the damper assembly to open or close the ventilation channel. The housing has a panel at the end near the fan and an air intake button and an air exhaust button located between the panel and the housing. The panel has a ventilation opening corresponding to the position of the fan and a baffle for closing or opening the ventilation opening. The air intake button, the air exhaust button, the fan, and the drive device are electrically connected to the control device.

[0010] Furthermore, the driving device is a servo motor, and the air valve assembly includes a valve plate rotatably installed in the ventilation channel and a rotating shaft fixed in the middle of the valve plate. One end of the rotating shaft is connected to the output end of the servo motor, and the edge of the valve plate is provided with a first sealing element for sealing with the inner wall of the ventilation channel.

[0011] Furthermore, the inner wall of the ventilation channel is provided with a first limiting plate and a second limiting plate for controlling the rotation position of the valve plate.

[0012] Furthermore, the opening of the ventilation channel near the air valve assembly is equipped with an insect screen; the opening of the ventilation channel near the fan is equipped with a protective cover.

[0013] Furthermore, the panel is magnetically connected to the box body via a magnetic fixing device. The magnetic fixing device includes a first magnetic component on the panel and a second magnetic component on the box body, wherein the first magnetic component and the second magnetic component are magnetically attracted to each other.

[0014] Furthermore, the panel is provided with a guide groove that is slidably connected to the edge of the baffle, and the baffle is provided with a handle that protrudes through the vent.

[0015] Furthermore, the side wall of the box is provided with a mounting plate with assembly holes and a second sealing element distributed in a ring.

[0016] Furthermore, the control device is connected to a remote communication module that communicates with a cloud server or control terminal.

[0017] Furthermore, the control device is connected to an environmental sensor for acquiring environmental data. The environmental sensor includes at least one of a temperature sensor, a humidity sensor, a CO2 detection sensor, and a PM2.5 detection sensor. The control device automatically controls the fan reversal, the opening and closing of the air valve assembly, and the fan speed adjustment based on the environmental data acquired by the environmental sensor.

[0018] Secondly, the present invention also provides a curtain wall ventilation system, including a curtain wall frame, wherein the curtain wall frame is provided with at least one hole, and the above-mentioned curtain wall ventilator is installed in the hole.

[0019] Compared with the prior art, the present invention provides a curtain wall ventilator and a curtain wall ventilation system including the curtain wall ventilator, which has the following beneficial effects:

[0020] This invention adopts a modular design approach, featuring a box-like structure adaptable to curtain wall installation. This integrated box incorporates ventilation channels, fans, and damper assemblies, simplifying installation and reducing maintenance costs while ensuring the curtain wall's mechanical stability. Simultaneously, by pressing the air inlet and exhaust buttons, the fan can operate in both directions, supporting flexible switching between bidirectional ventilation and providing both supply and exhaust ventilation modes. Furthermore, baffles and damper assemblies seal the ventilation channels from both indoor and outdoor sides. The damper assemblies are automatically opened and closed by a drive device, while the baffles are manually operated. This double-door sealing design balances sealing performance with ventilation flexibility. Through this structural design and integration, this invention achieves simplified integration of multiple functions within a limited space, solving problems such as unidirectional ventilation, insufficient sealing performance, and unreasonable overall integrated layout in existing curtain wall ventilation structures.

[0041] The present invention will now be described in further detail through detailed embodiments and in conjunction with the accompanying drawings.

[0042] Please refer to Figures 1-11 In one embodiment, a curtain wall ventilator 100 is provided, including a housing 1 for adapting to curtain wall installation and a control device 2 disposed on the housing 1. The housing 1 has a ventilation channel 11 that runs through both ends of the housing 1. One end of the ventilation channel 11 is provided with a fan 3 that can operate in both directions for air intake or exhaust. The other end of the ventilation channel 11 is provided with a damper assembly 4. The damper assembly 4 is connected to a drive device 5 for driving the damper assembly 4 to open or close the ventilation channel 11. The end of the housing 1 near the fan 3 is provided with a panel 6 and an air intake button 21 and an exhaust button 22 located between the panel 6 and the housing 1. The panel 6 is provided with a vent 61 corresponding to the position of the fan 3 and a baffle 7 for closing or opening the vent 61. The air intake button 21, the exhaust button 22, the fan 3, and the drive device 5 are electrically connected to the control device 2.

[0043] Specifically, fan 3 is a miniaturized, reversible, silent DC fan that supports 0.1-second reversal, adapts to different profile spaces, supports bidirectional ventilation, and can flexibly switch between supply and exhaust air, ensuring 100 m³ / h airflow for the curtain wall ventilator while providing silent active ventilation. Control device 2 includes a main control circuit board with a power cord installed in the electrical control box, featuring a built-in PWM power drive module and edge computing chip, supporting local logic decision-making. The forward and reverse rotation of fan 3 is controlled via PWM, as shown in the PWM curve... Figure 11 As shown, the control characteristics are as follows Figure 10 As shown. By pressing the air inlet button 21 or the air outlet button 22, the fan 3 and the air valve assembly 4 can be controlled to open and close using the dual-button operation method, making it more convenient to use.

[0044] The air intake and exhaust control logic is explained as follows:

[0045] (1) The power off state control device 2 detects the air intake button 21 and the air exhaust button 22 in real time. If the button is detected to be pressed, it enters the corresponding air intake state or air exhaust state.

[0046] (2) If the air intake button 21 is pressed during the air intake state, the air intake will be turned off, and if the exhaust button 22 is pressed, the exhaust state will be switched to. If the exhaust button 22 is pressed during the exhaust state, the exhaust will be turned off, and if the air intake button 21 is pressed, the air intake state will be switched to.

[0047] (3) When the air intake is in the air intake state: the air intake indicator light is on, the air exhaust indicator light is off, the air valve assembly 4 rotates 90 degrees counterclockwise to open, the PWM output has a duty cycle of 38%, and the fan 3 rotates clockwise (speed 1300rpm).

[0048] (4) When the exhaust is in the exhaust state: the exhaust indicator light is on, the air inlet indicator light is off, the air valve assembly 4 rotates 90 degrees counterclockwise to open, the PWM output has a duty cycle of 75%, and the fan 3 rotates counterclockwise (speed 1600rpm).

[0049] (5) Shutdown state: the air inlet indicator light is off, the air outlet indicator light is off, the air valve assembly 4 rotates 90 degrees clockwise to close, the PWM output has a duty cycle of 50%, and the fan 3 stops (speed 0 rpm).

[0050] By adopting a modular design, a single box 1 adaptable to curtain wall installation is incorporated. Box 1 integrates a ventilation duct 11, a fan 3, and a damper assembly 4, utilizing a confined space to share air supply and exhaust. This design accommodates installation within the curtain wall frame 200mm, simplifying installation and reducing maintenance costs while ensuring the curtain wall's mechanical stability. Simultaneously, by pressing the air inlet button 21 and the air outlet button 22, the fan 3 can rotate in both directions, supporting flexible switching between bidirectional ventilation and providing both intake and exhaust modes. Furthermore, the baffle 7 and the damper assembly 4 seal the ventilation duct 11 from both the indoor and outdoor sides. The damper assembly 4 is automatically opened and closed by a drive device 5, while the baffle 7 is manually operated. This double-door sealing design balances sealing performance with ventilation flexibility, ensuring that water tightness, air tightness, and thermal insulation meet curtain wall requirements. Through this structural design and coordination, the problems of existing curtain wall ventilation structures, such as unidirectional ventilation, insufficient sealing performance, and unreasonable overall integrated layout, are resolved.

[0051] like Figures 1-5As shown, in some specific embodiments, for example, the box body 1 is composed of two spliced ​​sections, forming an overall stepped cuboid shape. The section of box body 1 closer to the outdoor installation is smaller in volume and is constructed from stainless steel or other metal plates, improving the product's corrosion resistance. The section of box body 1 closer to the indoor installation is larger in volume and is constructed from non-metallic plate materials, improving the product's thermal insulation performance. This provides heat insulation, prevents condensation, and is beneficial for use in extremely cold regions.

[0052] refer to Figures 4-6 In some specific embodiments, the drive device 5 is a servo motor to precisely control the opening and closing of the damper assembly 4. The damper assembly 4 includes a valve plate 41 rotatably mounted in the ventilation channel 11 and a rotating shaft 42 fixed in the middle of the valve plate 41. One end of the rotating shaft 42 is connected to the output end of the servo motor, and the edge of the valve plate 41 is provided with a first sealing element 43 for sealing with the inner wall of the ventilation channel 11. Specifically, the servo motor is installed below the ventilation channel 11, and the rotating shaft 42 on the valve plate 41 is vertically centered in the ventilation channel 11; the first sealing element 43 is a weatherstripping, embedded in the outer periphery of the valve plate 41, which can form an elastic seal with the inner wall of the ventilation channel 11 when the valve plate 41 is in the closed state, thereby improving the sealing effect of the damper assembly 4 and ensuring that the valve plate 41 meets the water tightness, air tightness, and thermal insulation performance of the curtain wall when closed. By controlling the operating angle range of the servo motor, the valve plate 41 can be automatically rotated to open (e.g., rotated 90 degrees counterclockwise until the valve plate 41 is parallel to the ventilation direction) and close (e.g., rotated 90 degrees clockwise until the valve plate 41 is perpendicular to the ventilation direction).

[0053] refer to Figure 5 To further effectively limit the rotation range of the valve plate 41 and ensure that the valve plate 41 can be positioned in the open and closed states respectively, the inner wall of the ventilation channel 11 is provided with a first limiting plate 111 and a second limiting plate 112 for controlling the rotation position of the valve plate 41. The first limiting plate 111 corresponds to the open state, and the second limiting plate 112 corresponds to the closed state. Specifically, there are two of each of the first limiting plate 111 and the second limiting plate 112, and they are both centrally symmetrically distributed around the rotating shaft 42 of the valve plate 41.

[0054] refer to Figure 7 and Figure 8In some specific embodiments, the panel 6 is provided with guide grooves 63 that slide along the edge of the baffle 7. There are two guide grooves 63, symmetrically distributed on the left and right sides of the panel 6. The baffle 7 is provided with a handle 71 protruding through the vent 61. By gripping the handle 71, the baffle 7 can be pulled up or down to open or close the vent 61. Pulling down the baffle 7 opens the vent 61, revealing the air intake button 21 and the exhaust button 22 for easy operation and ventilation. Pulling up the baffle 7 covers the vent 61, further improving the overall airtightness of the curtain wall ventilator 100.

[0055] When the baffle 7 is pushed upward to close the vent 61, a magnetic positioning device is provided between the baffle 7 and the box body 1 to ensure that the baffle 7 remains stably in the closed vent 61 state. Specifically, the magnetic positioning device includes a third magnetic element 72 located on the baffle 7 and a fourth magnetic element 15 located on the box body 1, which are magnetically attracted to each other. As an example, the third magnetic element 72 on the baffle 7 is a magnet, and the fourth magnetic element 15 on the box body 1 is an iron sheet. Thus, when the baffle 7 moves upward to close the vent 61, the magnetic attraction between the magnet and the iron sheet is used to maintain the position of the baffle 7.

[0056] refer to Figures 1-5 In some specific embodiments, the side wall of the housing 1 is provided with a mounting plate 16 having assembly holes and a ring-shaped second sealing member 17. Specifically, the mounting plate 16 is L-shaped and distributed around the outer periphery of the side wall of the housing 1. The second sealing member 17 is an elastic sealing strip (such as EPDM / silicone composite material), which is ring-shaped and embedded in the strip groove at the outer periphery of the housing 1, and will not easily fall off.

[0057] During construction, the angle aluminum subframe 202 is pre-installed in the pre-drilled holes 201 in the curtain wall frame 200 for embedding the curtain wall ventilator 100. During installation, the curtain wall ventilator 100 is pushed into the hole 201, and the second sealing element 17 on the box 1 is used to press the outer angle aluminum subframe 202 to ensure sealing performance and achieve the function of waterproofing without glue. The mounting plate 16 on the box 1 is then locked to the inner angle aluminum subframe 202 with screws, thereby embedding the curtain wall ventilator 100 into the curtain wall frame 200.

[0058] refer to Figures 1-8 In some improved embodiments, panel 6 is further designed to be detachable. To facilitate quick assembly or disassembly and ensure precise installation, panel 6 is magnetically connected to the housing 1 via a magnetic fastening device. For example, Figure 8As shown, the magnetic fixing device includes a first magnetic member 62 located on the panel 6 and a second magnetic member 14 located on the box body 1. The first magnetic member 62 and the second magnetic member 14 are magnetically attracted to each other. Specifically, as an example, both the first magnetic member 62 and the second magnetic member 14 are elongated magnetic strips. The surface of the panel 6 near the box body 1 and the surface of the box body 1 near the panel 6 are respectively provided with corresponding snap-fit ​​grooves for installing the magnetic strips. Preferably, there are two first magnetic members 62 on the panel 6 and two second magnetic members 14 on the box body 1, symmetrically distributed from left to right, so that the panel 6 can be stably and firmly attached to the box body 1 and can be easily removed.

[0059] refer to Figure 1 , Figure 2 and Figure 5 In some improved embodiments, to further enhance protective performance, an insect screen 12 is provided at the opening of the ventilation duct 11 near the air valve assembly 4; a protective cover 13 is provided at the opening of the ventilation duct 11 near the fan 3. By installing an insect screen 12 on the outdoor side, insects and small animals from the outside can be prevented from entering the ventilation duct 11, while installing a protective cover 13 on the indoor side can improve the safety of using the fan 3 and prevent accidental contact with the fan 3 during manual operation.

[0060] In some improved embodiments, such as Figure 1 As shown, to facilitate intuitive understanding of the working status, the air intake button 21 and the air exhaust button 22 are further integrated with operation indicator lights to display the air intake status or the air exhaust status respectively. Specifically, the air intake button 21 has a ring-shaped LED backlit air intake indicator light distributed around its outer periphery, and the air exhaust button 22 has a ring-shaped LED backlit air exhaust indicator light distributed around its outer periphery. The air intake indicator light and the air exhaust indicator light are electrically connected to the control device 2.

[0061] In some improved embodiments, such as Figure 9 As shown, the control device 2 is also connected to a remote communication module 8 that communicates with a cloud server or control terminal. Thus, the remote communication module 8 can be used to achieve remote control or linkage with a smart home system, improving the level of intelligent control.

[0062] Specifically, the remote communication module 8 can be a data transmission module such as a cellular communication module, a short-range wireless module, or a low-power wide-area network (LPWAN) module. The cellular communication module can be an NB-IoT module, a 4G module, or a 5G module, relying on the operator's network to complete data transmission, offering wide coverage and low power consumption. The short-range wireless module can be a WiFi module, a Bluetooth module, or a ZigBee module, suitable for local interconnection. The LPWAN module can be a LoRa module or a Sigfox module, particularly suitable for long-distance, low-power data transmission designs. As an example, a WiFi module is used for remote interaction, enabling remote control and status feedback via a mobile app / cloud platform.

[0063] Furthermore, in some embodiments, such as Figure 12 As shown, by using the remote communication module 8 to build an Internet of Things for different curtain wall ventilators 100, two or more curtain wall ventilators 100 can be networked and controlled in a unified manner, which can further improve the overall ventilation efficiency and optimize the ventilation effect.

[0064] In some improved embodiments, such as Figure 9 As shown, to achieve automatic ventilation control, the control device 2 is further connected to an environmental sensor 9 for acquiring environmental data. Preferably, the environmental sensor 9 includes at least one of a temperature sensor, a humidity sensor, a CO2 detection sensor, and a PM2.5 detection sensor. The control device 2 automatically controls the fan 3 to switch directions, the damper assembly 4 to open and close, and the fan 3 speed to adjust based on the environmental data such as temperature, humidity, CO2 concentration, and PM2.5 acquired by the environmental sensor 9. In this way, automatic control can be achieved through linkage with the environmental sensor 9, automatically adjusting the ventilation state according to real-time environmental parameters. For example, when the indoor CO2 concentration is ≥1000ppm, exhaust ventilation is triggered.

[0065] In some specific application scenarios, for example, the air volume of the curtain wall ventilator 100 is ≥70m³ / h. 3 / h, operating noise ≤37dB, average wind speed is 2.1m / s, inlet speed of fan 3 >1200rpm, exhaust speed of fan 3 >1500rpm.

[0066] In addition, refer to Figure 13 In some embodiments, a curtain wall ventilation system is further provided, including a curtain wall frame 200, the curtain wall frame 200 having a pre-drilled hole 201, and a curtain wall ventilator 100 installed in the hole 201.

[0067] It should be noted that, in other embodiments, the number of holes 201 and curtain wall ventilators 100 can be reasonably selected according to actual ventilation requirements.

[0068] The above embodiments are merely illustrative of the concept and technical solution of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.

[0069] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
