Description

Ventilation and dehumidification skylights suitable for underground garages Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a ventilation and dehumidification skylight suitable for underground garages. Background Technology

[0002] With the acceleration of urbanization, underground parking garages, as a standard feature of modern buildings, are facing increasingly prominent ventilation and dehumidification issues. Because underground parking garages are often in a closed or semi-closed state with poor air circulation, they are prone to problems such as dampness, water accumulation, and deteriorating air quality. This not only accelerates the corrosion and damage of vehicles and equipment but also poses a threat to human health.

[0003] Therefore, underground parking garages have high ventilation requirements. Existing traditional underground parking garage ventilation systems mostly use mechanical ventilation equipment, which has drawbacks such as high energy consumption, high maintenance costs, and poor ventilation effect.

[0004] Ventilation skylights are installed at a high position outside the building, utilizing the differences in indoor and outdoor pressure, temperature, and air velocity to enhance natural ventilation. Existing ventilation skylights are typically used for ventilation in industrial plants, commercial building office areas, warehouses, etc., and their application in underground parking garages is relatively limited.

[0005] Existing ventilation skylights are typically horizontally installed, with the window opening horizontal when the skylight is open. Because underground parking garages are located at a lower elevation, and their roofs are usually at the ground floor level or the floor level of ordinary buildings, directly applying these skylights to ventilation in underground parking garages can easily lead to problems such as rainwater leakage and moisture intrusion.

[0006] Based on the aforementioned technical issues, a ventilation and dehumidification skylight suitable for underground parking garages is needed to adapt to the application scenarios of underground parking garages. Summary of the Invention

[0007] The purpose of this invention is to provide a ventilation and dehumidification skylight suitable for underground garages to improve the phenomena of rainwater leakage and moisture intrusion.

[0008] This utility model provides a ventilation and dehumidification skylight suitable for underground garages, including a skylight, a window frame base, and a ventilation component; the window frame base includes a first sidewall and a second sidewall that are horizontally opposite each other, the first sidewall being higher than the second sidewall, the top of the second sidewall being a first predetermined distance from the bottom of the window frame base, and the top of the window frame base having an inclined window between the first sidewall and the second sidewall, the skylight being operablely closable at the window; a ventilation opening is provided on the first sidewall, and the ventilation component is disposed at the ventilation opening.

[0009] The aforementioned ventilation and dehumidification skylight, with its tilted window design, enhances natural ventilation by utilizing the differences in indoor and outdoor pressure, temperature, and airflow velocity. Furthermore, the vent faces the second sidewall, facilitating horizontal airflow into the vent and further improving natural ventilation. When open, the skylight is angled to the window, with a portion of the skylight still obscuring the top of the window, helping to prevent rainwater from entering. Additionally, the top of the second sidewall is at a predetermined distance from the bottom of the window frame, ensuring the top of the second sidewall is higher than the outer surface of the garage roof, preventing water from the roof from flowing into the window frame and mitigating rainwater leakage and moisture intrusion. Equipped with ventilation components, the skylight can also provide forced ventilation or exhaust to meet diverse ventilation, dehumidification, and cooling needs within the garage.

[0010] Optionally, the lowest point of the vent is at a second predetermined distance from the bottom of the window frame base. This second predetermined distance prevents water from flowing into the vent when rainwater intrudes into the window frame base. By setting the first distance on the second sidewall in conjunction with the second distance at the lowest point of the vent, a reliable waterproofing effect is achieved, thereby improving the effectiveness of preventing rainwater leakage and moisture intrusion. And / or, the center of the vent is higher than the top of the second sidewall, ensuring that airflow above the second sidewall can directly flow into the interior of the vent, thus improving ventilation.

[0011] Optionally, the outer side of the skylight is provided with a first mounting position for installing photovoltaic modules.

[0012] Optionally, the ventilation and dehumidification skylight suitable for underground garages further includes a frame assembly, which is disposed inside the window frame base, and the skylight is rotatably disposed on the side of the frame assembly near the first sidewall. The frame assembly, as a skeleton structure, helps to improve the structural strength and rigidity of the entire ventilation and dehumidification skylight. The frame assembly also serves as an installation base, facilitating the installation of the skylight.

[0013] Optionally, the outer wall of the window frame seat is provided with a second mounting position, which is used to install a battery and / or a sensing component and / or a control component;

[0014] A portion of the skylight extends above the second mounting position. The skylight then shields the second mounting position, protecting the components mounted thereon.

[0015] Optionally, the second mounting position is disposed on the first sidewall and located above the vent.

[0016] Optionally, the ventilation and dehumidification skylight suitable for underground garages also includes a sealing strip, which is disposed around the perimeter of the window and / or on the side of the skylight near the window.

[0017] Optionally, the ventilation assembly includes a fan that can rotate in both directions.

[0018] Optionally, the ventilation and dehumidification skylight suitable for underground garages also includes a dustproof net, which is disposed on the inside of the first side wall and covers the ventilation opening.

[0019] Optionally, the ventilation and dehumidification skylight suitable for underground garages further includes louvers, which are disposed on the outer wall of the first side wall and cover the ventilation assembly.

[0020] In summary, the ventilation and dehumidification skylight suitable for underground parking garages includes a skylight, a window frame base, and a ventilation component. The window frame base includes a first sidewall and a second sidewall that are horizontally opposite each other. The first sidewall is higher than the second sidewall. The top of the second sidewall is a first predetermined distance from the bottom of the window frame base. The top of the window frame base has an inclined window between the first sidewall and the second sidewall. The skylight is closable and can be opened and closed at the window. A ventilation opening is provided on the first sidewall, and the ventilation component is disposed at the ventilation opening.

[0021] With this configuration, the aforementioned ventilation and dehumidification skylight, through its tilted window design, helps enhance natural ventilation by utilizing the differences in indoor and outdoor pressure, temperature, and airflow velocity. Furthermore, the vent faces the second sidewall, facilitating horizontal airflow into the vent and further improving natural ventilation. In addition, when the skylight is open, it forms an angle with the window, with a portion of the skylight still obscuring the top of the window, helping to prevent rainwater from entering. Moreover, the top of the second sidewall is at a predetermined distance from the bottom of the window frame, ensuring that the top of the second sidewall is higher than the outer surface of the garage roof, preventing water accumulation on the garage roof from flowing into the interior of the window frame and helping to improve rainwater leakage and moisture intrusion.

[0022] The aforementioned ventilation and dehumidification skylights are equipped with ventilation components and can also perform forced ventilation or exhaust to meet the diverse ventilation, dehumidification, and cooling needs of the garage. Attached Figure Description

[0040] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the ventilation and dehumidification skylight suitable for underground parking garages proposed by this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0041] As used in this invention, the singular forms “a,” “an,” and “the” include plural objects; the term “or” is generally used to mean “and / or”; the term “a number” is generally used to mean “at least one”; and the terms “at least two” or “more than” are generally used to mean “two or more”. Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with “first,” “second,” or “third” may explicitly or implicitly include one or at least two of that feature. Furthermore, the terms "installed," "connected," and "attached," as used in this utility model, and the term "set" on one element from another, should be interpreted broadly. They generally only indicate a connection, coupling, cooperation, or transmission relationship between the two elements, which can be direct or indirect through an intermediate element. They should not be construed as indicating or implying a spatial positional relationship between the two elements, meaning one element can be located inside, outside, above, below, or to one side of the other element, unless otherwise explicitly stated. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances. Additionally, directional terms such as above, below, up, down, upward, downward, left, and right are used relative to exemplary embodiments as shown in the figures, with upward or up direction pointing towards the top of the corresponding figure, and downward or down direction pointing towards the bottom of the corresponding figure.

[0042] As shown in Figures 1 and 2, this embodiment provides a ventilation and dehumidification skylight suitable for underground garages, including a skylight 10, a window frame base 20, and a ventilation assembly 30;

[0043] As shown in Figure 2, the window frame base 20 has an overall box-like structure with an open top. The bottom of the window frame base 20 is horizontal, and its sides are formed by four side walls. Each of the four side walls is connected to its base plate to form a box-like structure that is closed at the bottom and open at the top.

[0044] Specifically, the window frame base 20 includes a first sidewall 21 and a second sidewall 22 that are horizontally opposite each other. The first sidewall 21 is higher than the second sidewall 22. The first sidewall 21 and the second sidewall 22 are connected by an approximately trapezoidal third sidewall and a fourth sidewall. The side of the third sidewall and the fourth sidewall that is closer to the first sidewall 21 is at the same height as the first sidewall 21, and the side that is closer to the second sidewall 22 is at the same height as the second sidewall 22. The first sidewall 21 and the second sidewall 22 are parallel, the third sidewall and the fourth sidewall are parallel, and the first sidewall 21 is perpendicular to the third sidewall. The first sidewall 21, the second sidewall 22, the third sidewall and the fourth sidewall together form a box-shaped structure.

[0045] In this embodiment, the first sidewall 21, the second sidewall 22, the third sidewall, and the fourth sidewall are all plate structures, and the bottom plate of the window frame base 20 is a rectangular plate structure. The first sidewall 21, the second sidewall 22, the third sidewall, and the fourth sidewall are connected to the four sides of the bottom plate of the window frame base 20, and the first sidewall 21, the second sidewall 22, the third sidewall, and the fourth sidewall are perpendicular to the bottom plate of the window frame base 20.

[0046] The aforementioned window frame base 20 consists of four side walls and a floor, and its vertical projection gives it a rectangular structure. In other alternative embodiments, the window frame base 20 may have more side walls, such as a hexagonal structure or other irregular shapes. The specific shape of the window frame base 20 can be adaptively adjusted based on ventilation or aesthetic requirements.

[0047] The top of the second sidewall 22 is at a first predetermined distance from the bottom of the window frame base 20. The lower end face (base plate) of the window frame base 20 is sealed and fixed to the roof of the garage using expansion bolts and waterproof sealant, ensuring installation stability and sealing. The first predetermined distance should be set so that after the entire ventilation and dehumidification skylight is installed on the outdoor roof of the garage, the top of the second sidewall 22 is higher than the upper surface of the roof, to prevent water accumulation on the roof from flowing into the interior of the window frame base 20. The actual size of the first predetermined distance can be set based on actual usage requirements, for example, 0.1m-1m.

[0048] The aforementioned window frame base 20, due to the height difference between the first sidewall 21 and the second sidewall 22, has an inclined window 23 at its top between the first sidewall 21 and the second sidewall 22. The window 23 gradually decreases in height from the first sidewall 21 to the second sidewall 22. Preferably, the height difference between the first sidewall 21 and the second sidewall 22 results in an inclination angle of the window 23 relative to the horizontal plane greater than 30°. The skylight 10 is closable and mounted on the window 23. As shown in Figure 1, the side of the skylight 10 closest to the first sidewall 21 is rotatable, so the side of the skylight 10 closest to the second sidewall 22 can swing. When the skylight 10 is opened, the side of the skylight 10 closest to the second sidewall 22 swings upward, opening the window 23. The skylight 10 and the window 23 form a V-shaped structure, which facilitates the guidance of natural wind into the window 23. When the skylight 10 is closed, the side of the skylight 10 closest to the second side wall 22 swings downward, at which point the skylight 10 covers the top of the first side wall 21 and the second side wall 22, and the window 23 is closed.

[0049] A ventilation opening 24 is provided on the first sidewall 21, and the ventilation component 30 is disposed on the ventilation opening 24.

[0050] As shown in Figure 2, the ventilation openings 24 are horizontally arranged, and there are two circular openings 24. The ventilation assembly 30 includes two reversible fans, which are respectively and conformally installed in the two ventilation openings 24. The fans can achieve forced ventilation or exhaust by reversing their rotation. In other alternative embodiments, the shape and number of ventilation openings 24 can be adaptively adjusted based on the installation requirements of the ventilation assembly 30. For example, the ventilation openings 24 can be set as rectangular opening structures or other shapes, and the number of ventilation openings 24 can be one, three, or more.

[0051] As shown in Figure 1, when the skylight 10 is opened, the lower side (the side closest to the second side wall 22) of the window 23 is opened. At this time, natural airflow can flow horizontally from the lower side to the higher side of the window 23 (i.e., from the second side wall 22 to the first side wall 21) and flow into the garage through the vent 24.

[0052] The aforementioned ventilation and dehumidification skylight, with its angled window 23, enhances natural ventilation by utilizing the differences in indoor and outdoor pressure, temperature, and airflow velocity. Furthermore, the vent 24 faces the second sidewall 22, facilitating horizontal airflow into the vent 24 and further improving natural ventilation. When the skylight 10 is open, it forms an angle with the window 23, with a portion of the skylight 10 still obscuring the top of the window 23, helping to prevent rainwater from entering. Additionally, the top of the second sidewall 22 is at a predetermined distance from the bottom of the window frame base 20, ensuring that the top of the second sidewall 22 is higher than the outer surface of the garage roof, preventing water from the garage roof from flowing into the interior of the window frame base 20 and improving rainwater leakage and moisture intrusion.

[0053] The aforementioned ventilation and dehumidification skylight is equipped with a ventilation component 30, which can also perform forced ventilation or exhaust to meet the diverse ventilation, dehumidification and cooling needs in the garage.

[0054] Furthermore, the center of the vent 24 is higher than the top of the second sidewall 22. This ensures that the airflow above the second sidewall 22 can flow directly into the interior of the vent 24, thereby improving ventilation efficiency. Preferably, the lowest point of the vent 24 is at the same height as the top of the second sidewall 22. In this case, the second sidewall 22 will not obstruct the vent 24 in the horizontal direction, which helps to reduce wind resistance and improve ventilation efficiency.

[0055] Furthermore, the lowest point of the vent 24 is at a second predetermined distance from the bottom of the window frame base 20. This second predetermined distance is preferably greater than 0.2m. If rainwater intrudes into the window frame base 20, this second predetermined distance prevents water from flowing into the vent 24. By setting the first distance on the second sidewall 22, in conjunction with the second distance at the lowest point of the vent 24, a reliable waterproofing effect is achieved, thereby improving the effectiveness of preventing rainwater leakage and moisture intrusion.

[0056] Furthermore, the ventilation and dehumidification skylight suitable for underground garages also includes a frame assembly 40, which is disposed inside the window frame base 20, and the skylight 10 is rotatably disposed on the side of the frame assembly 40 near the first side wall 21.

[0057] As shown in Figure 2, the frame assembly 40 has a trapezoidal frame structure that matches the internal structure of the window frame base 20. As shown in Figure 2, the side of the frame assembly 40 closest to the first sidewall 21 is a first rectangular frame, with a reinforcing beam vertically connected to the middle of the rectangular frame. The side of the frame assembly 40 closest to the second sidewall 22 is a second rectangular frame. The first rectangular frame is higher than the second rectangular frame, and the bottom widths of the first and second rectangular frames are connected by two horizontal beams, while the top widths of the first and second rectangular frames are connected by two diagonal beams.

[0058] The overall shape of the frame assembly 40 is adapted to the window frame base 20, and the frame assembly 40 is conformally installed inside the window frame base 20. The four posts of the frame assembly 40 (the posts on both sides of the first rectangular frame and the posts on both sides of the second rectangular frame) conformally fit the four corners inside the window frame base 20. The side of the frame assembly 40 closest to the first side wall 21 is approximately at the same height as the first side wall 21, and the side of the frame assembly 40 closest to the second side wall 22 is approximately at the same height as the second side wall 22. The frame assembly 40 can be connected to the window frame base 20 by welding or bolting.

[0059] The frame assembly 40, serving as a skeleton structure, helps improve the structural strength and rigidity of the entire ventilation and dehumidification skylight. The frame assembly 40 also serves as a mounting base, facilitating the installation of the skylight 10. Specifically, the upper crossbeam (the upper crossbeam of the first rectangular frame) of the frame assembly 40 near the first sidewall 21 is used to mount the skylight 10, for example, by rotating the outer frame of the skylight 10 onto this crossbeam via hinges. When the skylight 10 rotates, the side of the skylight 10 near the second sidewall 22 adaptively swings to open or close the window 23.

[0060] Please continue referring to Figures 1 and 2. The ventilation and dehumidification skylight suitable for underground parking garages also includes an electric actuator 91. In this embodiment, two electric actuators 91 are provided, and the two electric actuators 91 are respectively connected to both sides of the width of the skylight 10. One end of the electric actuator 91 is rotatably connected to the outer frame of the skylight 10, and the other end is rotatably connected to the bottom of the frame assembly 40 through a movable base. The skylight 10 is driven to open or close by the synchronous movement of the two electric actuators 91.

[0061] When the telescopic rod of the electric push rod 91 extends, the two ends of the electric push rod 91 rotate accordingly, and push the skylight 10 to rotate around the hinge, thereby opening the window 23; when the telescopic rod of the electric push rod 91 retracts, it drives the skylight 10 to fall back, thereby closing the window 23.

[0062] In this embodiment, the sunroof 10 is driven by an electric actuator. In other alternative embodiments, the sunroof 10 can be driven by a hydraulic actuator, a motor drive, or other known driving methods.

[0063] Please continue to refer to Figures 1 and 2. In this embodiment, the outer side of the skylight 10 is provided with a first mounting position 11 for installing photovoltaic modules. The photovoltaic module 92 is installed in the first mounting position 11. The photovoltaic module 92 is installed on the outer side of the skylight 10, and its monocrystalline silicon cells convert solar energy into electrical energy.

[0064] In this embodiment, the first mounting position 11 is a rectangular recessed area located on the outer side of the skylight 10's outer frame. Correspondingly, the photovoltaic module 92 is a rectangular structure adapted to this recessed area, fitting comfortably into it for easy installation and fixation. In other alternative embodiments, the specific shape of the recessed area of ​​the first mounting position 11 can be adaptively adjusted based on the actual structure of the photovoltaic module 92, or the first mounting position 11 can be directly located at a position on the outer frame of the skylight 10, allowing the photovoltaic module 92 to be installed via bolt connection.

[0065] In this embodiment, the skylight 10 has a rectangular structure and an outer frame with a translucent glass installed in the middle. The first mounting position 11 is located on the outer side of the skylight 10's outer frame, near the edge of the first sidewall 21. The area of ​​the skylight 10 corresponding to the first mounting position 11 is made of a non-translucent material. The location of the first mounting position 11 ensures that the photovoltaic module 92 is positioned at the edge of the skylight 10, preventing it from occupying the central light-receiving area. Furthermore, the location of the photovoltaic module 92 also facilitates electrical connection with the battery. Additionally, the location of the first mounting position 11 on the outer side of the skylight 10's outer frame, near the edge of the first sidewall 21, also prevents added weight to the area near the second sidewall 22, helping to adjust the skylight 10's center of gravity, reducing the driving force required to open the skylight 10, and facilitating its opening.

[0066] Furthermore, referring to Figures 1 and 2, the ventilation and dehumidification skylight suitable for underground garages also includes a sealing strip 50. The sealing strip 50 is made of an elastic material, such as rubber. In this embodiment, the sealing strip 50 is disposed on the side of the skylight 10 near the window 23. The sealing strip 50 has a rectangular closed-loop structure and is fitted onto the skylight 10. The shape of the sealing strip 50 is adapted to the window 23. When the skylight 10 is closed, the sealing strip 50 is sealed and fitted around the window 23. The sealing strip 50 is deformed by the compression of the skylight 10 and the window 23, filling the gap between them to achieve a good seal, thereby enhancing the sealing performance between the skylight 10 and the window frame base 20 and preventing rainwater and moisture penetration.

[0067] In other alternative embodiments, the sealing strip 50 may be disposed around the window 23. When the skylight 10 is closed, the skylight 10 presses against the sealing strip 50 to enhance the sealing between the skylight 10 and the window frame base 20.

[0068] In other alternative embodiments, the sealing strip 50 may be of other shapes, and the shape of the sealing strip 50 may be adjusted based on the shape adaptability of the skylight 10 and the window 23.

[0069] Furthermore, referring to Figures 1 and 2, the ventilation and dehumidification skylight suitable for underground parking garages also includes a dustproof net 60. The dustproof net 60 is disposed on the inner side of the first sidewall 21 and covers the ventilation opening 24. The dustproof net 60 can be connected to the first sidewall 21 via clips, bolts, or other known connection methods. The dustproof net 60 can be a planar structure or a box-shaped structure with one open end, in which case its open end is connected to the inner side of the first sidewall 21 and covers the ventilation opening 24. The dustproof net 60 has a mesh structure and is used to filter large particles. The specific mesh size of the dustproof net 60 can be set based on actual usage requirements.

[0070] The louvers 70 are disposed on the outer wall of the first side wall 21 and cover the ventilation assembly 30. That is, the ventilation assembly 30 is integrated and installed on the higher side of the window frame base 20, and is located between the dustproof net 60 and the louvers 70.

[0071] The dust filter 60 helps filter larger solid particles, ensuring clean airflow. The louvers 70 protect the vents 24 or ventilation components 30, while also allowing for flexible opening or closing of the connection between the ventilation and dehumidification skylight and the garage interior as needed.

[0072] Referring to Figures 3 and 4, in this embodiment, the louver 70 is opened or closed by a drive assembly 80. The drive assembly 80 includes a control lever 81, a slide rail 82, an electric telescopic rod 83, a transmission rod 84, and a slider 85.

[0073] The louvers 70 are set horizontally and multiple louvers are arranged vertically. Each louver 70 is connected to one end of a swing arm. The middle part of the swing arm is rotatably mounted on the louver frame. The other end of the swing arm corresponding to each louver 70 is rotatably connected to the control rod 81. Therefore, when the control rod 81 moves up and down, it can drive all the swing arms to swing, thereby realizing the rotation drive of all the louvers 70, so that the louvers open or close.

[0074] The slide rail 82 is fixedly connected to the frame of the louver 70 (or a part of the frame serves as the slide rail 82). The slide rail 82 extends vertically and has a vertically provided sliding groove 821. The control rod 81 also extends vertically and is vertically movable within the sliding groove 821. The bottom of the electric telescopic rod 83 is fixed to the window frame base 20. The top (telescopic end) of the electric telescopic rod 83 is rotatably connected to the intersection of two V-shaped transmission rods 84. The other ends of the two transmission rods 84 are rotatably connected to the slider 85. The slider 85 is vertically slidable with a single degree of freedom within the sliding groove 821. The slider 85 is connected to the control rod 81, so when the slider 85 slides vertically within the sliding groove 821, it drives the control rod 81 to move vertically synchronously.

[0075] Therefore, in the above structure, the electric telescopic rod 83 drives the slider 85 to slide vertically along the sliding groove 821, the slider 85 drives the control rod 81 to move vertically, the control rod 81 drives each swing arm of the louver 70 to swing, thereby driving the louver 70 to rotate, so that the louver 70 opens or closes.

[0076] Please continue to refer to Figures 1 and 2. The outer wall of the window frame base 20 is provided with a second mounting position 25, which is used to install a battery and / or sensing components and / or control components.

[0077] As shown in Figures 1 and 2, the second mounting position 25 is located on the outside of the first sidewall 21 and above the vent 24. A portion of the skylight 10 extends above the second mounting position 25, thus the skylight 10 shields the second mounting position 25 to protect the components mounted on the second mounting position 25.

[0078] In this embodiment, the second mounting position 25 utilizes a portion of the outer wall of the first sidewall 21, and the first sidewall 21 is not specially shaped for the second mounting position 25. In other alternative embodiments, a recessed area or other special shape may be adaptively provided on the outer wall of the first sidewall 21 to form the second mounting position 25.

[0079] In this embodiment, a battery 93, a sensing component 94, and a control component 95 are installed on the second mounting position 25. The battery 93 is electrically connected to the photovoltaic module 92, allowing the electrical energy generated by the photovoltaic module 92 to be transferred to the battery 93 for storage. The battery 93 is also connected to the electric actuator 91 to supply power to the electric actuator 91. The control component 95 is connected to the battery 93 to obtain battery power information. When there is sufficient sunlight, the electrical energy generated by the photovoltaic module 92 is used first to maintain system operation, and excess electrical energy is stored in the battery 93; at night or when there is insufficient sunlight, the battery 93 supplies power to the entire system to ensure the continuous and stable operation of the skylight.

[0080] The sensing component 94 includes a humidity sensor, a temperature sensor, a PM2.5 sensor, and a TVOC sensor. The sensing component 94 is located on the outer wall of the first side wall 21, close to the garage side. When air is exhausted from the garage through the ventilation component 30, the sensing component 94 can collect real-time air environment data of the underground garage, including air humidity, air temperature, and air quality. Air quality data includes PM2.5 and TVOC (total volatile organic compounds). This air environment data is then transmitted to the control component 95.

[0081] The control component 95 is also connected to the electric telescopic rod 83, the electric push rod 91, and the ventilation component 30 to control the operating status of each component. The control component 95 is wired to the ventilation component 30 to realize the forward and reverse rotation or stop control of the ventilation component 30, so as to realize the switching between exhaust and air intake functions.

[0082] The control component 95 typically includes at least one processor, which may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0083] The at least one processor can communicate with multiple peripheral devices via a bus subsystem. These peripheral devices may include storage systems, user interface input devices, user interface output devices, and network interfaces.

[0084] When the humidity value detected by the sensing component 94 reaches or exceeds the preset humidity threshold (e.g., 70% RH), and the air quality data is greater than the quality threshold (PM2.5 is greater than the corresponding threshold or TVOC is greater than the corresponding threshold), ventilation is required. The control component 95 sends an exhaust command to the ventilation component 30, and the ventilation component 30 operates in exhaust mode to extract air from the garage; at the same time, the control component 95 sends an opening signal to the drive component 80, and the electric telescopic rod 83 actuates to drive the louvers 70 to open; simultaneously, the control component 95 sends an opening signal to the electric push rod 91, and the electric push rod 91 actuates to drive the skylight 10 to open, and the humid and polluted air in the underground garage is discharged after being filtered by the ventilation component 30 and the dust screen 60.

[0085] When fresh air needs to be introduced, the control component 95 controls the ventilation component 30 to reverse and switch to air intake mode. Simultaneously, the control component 95 sends an opening signal to the drive component 80, causing the electric telescopic rod 83 to actuate and open the louvers 70. At the same time, the control component 95 sends an opening signal to the electric push rod 91, causing the electric push rod 91 to actuate and open the skylight 10. Fresh outside air enters the garage after being filtered by the ventilation component 30 and the dust filter 60. When the sensor component 94 detects that the temperature in the underground garage exceeds the set upper limit, the control component 95 sends a signal to the ventilation component 30 to increase the blade speed of the ventilation component 30, thereby increasing the air intake. Furthermore, the control component 95 determines the ventilation volume based on the detection data from the sensor component 94 and controls the opening angle of the skylight 10; the greater the ventilation volume, the greater the opening angle of the skylight 10.

[0086] As shown in Figure 1, the state corresponding to the skylight and louvers being open is applicable to the operation of the ventilation component 30 being rotated in both directions for ventilation or exhaust.

[0087] When the detected humidity value is less than the humidity threshold, the air quality data is less than the air quality threshold, and the temperature in the underground garage is less than the set upper limit, the control component 95 controls the ventilation component 30 to stop. At the same time, the control component 95 sends a closing signal to the drive component 80, and the electric telescopic rod 83 drives the louvers 70 to close. Simultaneously, the control component 95 sends a closing signal to the electric push rod 91, and the electric push rod 91 drives the skylight 10 to close.

[0088] Figure 5 corresponds to the state where the skylight and louvers are closed, which is applicable to the working condition of the ventilation component 30 being stopped and not ventilated.

[0089] In addition, as shown in Figures 6 and 7, the ventilation and dehumidification skylight also has two intermediate states. Figure 6 corresponds to the state where the skylight is open and the louvers are closed, and Figure 7 corresponds to the state where the skylight is closed and the louvers are open.

[0090] The aforementioned skylight system, through its structural design and intelligent control system, effectively overcomes the shortcomings of existing technologies, such as low ventilation efficiency, high energy consumption, poor sealing, and weak environmental adaptability. Through precise environmental sensing and intelligent control, it solves the problems of dampness and ventilation in underground parking garages, offering advantages in energy saving, high efficiency, and intelligence.

[0091] In summary, the ventilation and dehumidification skylight suitable for underground garages includes a skylight 10, a window frame base 20, and a ventilation component 30. The window frame base 20 includes a first sidewall 21 and a second sidewall 22 that are horizontally opposite each other. The first sidewall 21 is higher than the second sidewall 22. The top of the second sidewall 22 is at a first predetermined distance from the bottom of the window frame base 20. The top of the window frame base 20 has an inclined window 23 between the first sidewall 21 and the second sidewall 22. The skylight 10 is closable and disposed in the window 23. A ventilation opening 24 is provided on the first sidewall 21, and the ventilation component 30 is disposed in the ventilation opening.

[0092] With this configuration, the aforementioned ventilation and dehumidification skylight, through the inclined setting of window 23, helps to enhance natural ventilation by utilizing the differences in indoor and outdoor pressure, temperature, and air velocity. Furthermore, the vent 24 faces the second side wall 22, facilitating horizontal airflow into the vent 24 and further improving natural ventilation. In addition, when the skylight 10 is open, it forms an angle with window 23, with a portion of the skylight 10 still obscuring the top of window 23, helping to prevent rainwater from entering. Moreover, the top of the second side wall 22 is at a predetermined distance from the bottom of the window frame base 20, ensuring that the top of the second side wall 22 is higher than the outer surface of the garage roof, preventing water accumulation on the garage roof from flowing into the interior of the window frame base 20, thus helping to improve rainwater leakage and moisture intrusion.

[0093] The aforementioned ventilation and dehumidification skylight is equipped with a ventilation component 30, which can also perform forced ventilation or exhaust to meet the diverse ventilation, dehumidification and cooling needs in the garage.

[0094] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0095] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
