Description
Technical Field
[0001] This utility model relates to the field of cleanroom air supply devices, specifically an air supply device and an energy-saving cleanroom. Background Technology
[0002] Cleanrooms are special enclosed spaces with strict control over environmental parameters such as air cleanliness, temperature, humidity, and pressure gradient. They are widely used in fields that are highly sensitive to environmental pollutants, such as semiconductor manufacturing, biomedicine, precision electronics, and food processing. Their core function is to effectively filter impurities such as particles, microorganisms, and harmful gases in the air through a series of air purification and environmental control technologies, and to stably control indoor environmental parameters within the range required by specific processes.
[0003] As the core component of the cleanroom environmental control system, the air supply device directly determines the cleanliness, temperature and humidity uniformity, and energy efficiency of the cleanroom. It plays an irreplaceable role in realizing the functions of the cleanroom. Working in conjunction with the air filtration system, the air supply device delivers deeply purified air to the cleanroom at a specific wind speed and airflow pattern, continuously diluting and removing pollutants generated indoors, maintaining a stable clean environment. Furthermore, the air supply device is also a key carrier for regulating the temperature and humidity of the cleanroom. The cold and hot airflows processed by the air conditioning system are precisely distributed to various areas of the room through the air supply device, ensuring that there is no significant gradient difference in temperature and humidity within the space.
[0004] In current cleanroom air supply systems, air ducts and outlets are generally concentrated in the ceiling area, forming a single airflow organization pattern of top air supply. Whether it is warm air needed for heating in winter or cold air needed for cooling in summer, it is uniformly delivered downward to the room through the air outlets on the ceiling. However, when delivering warm air in winter, there is a significant energy consumption shortcoming. Since the density of hot air is much lower than that of cold air, it is easy to accumulate at the top to form a layer of hot air, which is difficult to diffuse naturally downward to the middle and lower areas of the cleanroom. This results in a temperature gradient in the room where the upper part is hot and the lower part is cold. In order to meet the overall heating needs of the cleanroom, the air conditioning system has to increase its output power, resulting in a large amount of ineffective energy consumption. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide an air supply device and an energy-saving cleanroom to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an air supply device and an energy-saving cleanroom, comprising a cleanroom and an air supply device. The air supply device is installed on the outer wall of the cleanroom. A return air duct and an air duct are respectively provided on both sides of the air supply device. A first air supply pipe and a second air supply pipe are respectively connected to the ends of the air ducts. Multiple sets of first connecting pipes and second connecting pipes are respectively installed on one side of the outer wall of the first air supply pipe and the second air supply pipe. An air guide assembly is installed inside the return air duct and the air duct. The air guide assembly includes a stepper motor. A rotating rod is installed at the end of the stepper motor. A baffle plate and a first adjusting plate are respectively fixed on both sides of the rotating rod. A second adjusting plate is provided at one end of the first adjusting plate.
[0007] By adopting the above technical solution, the problem of traditional cleanroom ceiling air supply duct structures requiring increased power to meet heating demands when delivering warm air is solved. The cleanroom has identical return air ducts and air ducts on both sides. When the air supplied by the air supply device is warm air, the air guide component inside the air duct directs the warm air to the second air supply duct, allowing the warm air to flow from the bottom to the top of the cleanroom and back to the air supply device through the return air duct at the top. After being delivered from the bottom, the warm air follows the natural upward movement of hot air, quickly filling the entire room without requiring additional power from the air conditioner. This avoids the energy waste caused by the accumulation of hot air at the top when delivering warm air through traditional ceiling air supply duct structures.
[0008] The present invention is further configured such that both sides of the inner wall of one end of the air duct are provided with blocking grooves, and one end of the inner wall of the first air supply duct and the second air supply duct are fixed with limit plates.
[0009] Preferably, when the air guide assembly is adjusted, one side wall of the baffle plate and the second adjustment plate are tightly fitted with the walls of the blocking groove and the limiting plate, respectively, so that the air guide assembly can guide the air inside the air duct to the second air supply duct.
[0010] The present invention is further configured such that two sets of sliders are fixed on one side of the outer wall of the first adjusting plate, and two sets of sliding grooves are provided on one side of the outer wall of the second adjusting plate.
[0011] Preferably, when the second adjusting plate moves, the second adjusting plate can slide on the outer wall of one side of the first adjusting plate.
[0012] The present invention is further configured such that the slider is T-shaped and is located in the groove.
[0013] Preferably, during the movement of the second adjusting plate, the T-shaped slider can limit the movement direction of the second adjusting plate, so that the second adjusting plate can slide horizontally along the wall of the first adjusting plate.
[0014] The present invention is further configured such that two sets of fixing plates are fixed to the outer walls of the first adjusting plate and the second adjusting plate, and springs are fixedly installed on the outer walls of the fixing plates, and the springs are always in a compressed state.
[0015] Preferably, during the process of the air guide assembly guiding the air inside the duct, the spring is initially in a compressed state. The spring in the compressed state pushes the second adjusting plate away from the first adjusting plate through the fixed plate fixedly connected to its end, so that the second adjusting plate and the first adjusting plate can be in an extended state.
[0016] The present invention is further configured such that bearings are installed at both ends of the rotating rod, and the rotating rod is mounted on the pipe via the bearings.
[0017] Preferably, the stepper motor is fixedly installed on the outer wall of the pipe and is electrically connected to the control panel inside the clean room. When the stepper motor drives the rotating rod to rotate, the bearings installed at both ends of the rotating rod can support the rotating rod.
[0018] The present invention is further configured such that four pairs of pulleys are installed at one end of the second adjusting plate, and each pair of pulleys is respectively arranged on both sides of the end wall of the second adjusting plate.
[0019] Preferably, when the second adjusting plate rotates, the first air supply duct wall surface presses against multiple sets of pulleys at the end of the second adjusting plate, causing the second adjusting plate to move towards the first adjusting plate. The installation of the pulleys can reduce the wear on the inner wall of the duct during the rotation adjustment process of the second adjusting plate.
[0020] The present invention is further configured such that the pipe structure of the return air duct is the same as the pipe structure formed by the air duct, the first air supply duct, and the second air supply duct.
[0021] Preferably, after the air supply device delivers warm air from the bottom of the cleanroom, the warm air can flow out from the top of the cleanroom.
[0022] In summary, the present invention has the following main advantages: 1. This utility model solves the problem that traditional cleanroom ceiling air supply duct structures require increased power to meet heating demands when delivering warm air by setting up an air supply device, return air duct, air duct, first air supply duct, second air supply duct, and air guide component. The cleanroom has return air ducts and air ducts of the same structure on both sides. When the air supplied by the air supply device is warm air, the air guide component inside the air duct guides the warm air to the second air supply duct, so that the warm air flows from the bottom to the top of the cleanroom and flows back to the air supply device from the return air duct at the top of the cleanroom. After the warm air is delivered from the bottom, it follows the natural rising characteristic of hot air and can quickly fill the whole room without the need for the air conditioner to increase its power. This avoids the energy waste caused by the accumulation of hot air at the top when the traditional air supply duct structure delivers warm air from the top.
[0023] 2. This utility model solves the problem that the traditional air supply duct structure set at the top of the cleanroom cannot be adjusted according to the type of air supply by setting up a baffle plate, a first adjusting plate, a second adjusting plate, a stepper motor, a blocking groove, and a limiting plate. When warm air needs to be supplied to the cleanroom, the stepper motor drives the baffle plate and the first adjusting plate to rotate through the rotating rod, so that one end of the baffle plate is inserted into the blocking groove at the top of the inner wall of the air duct. When one side of the wall of the second adjusting plate is tightly attached to the limiting plate on the inner wall of the second air supply duct, the air guide assembly guides the warm air supplied inside the air duct to the inside of the second air supply duct. When cold air is supplied, the stepper motor drives the air guide assembly to rotate in the opposite direction, so that the air supply device can supply cold air from the top of the cleanroom to the inside of the cleanroom, and warm air can supply warm air from the bottom to the inside of the cleanroom.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0027] The embodiments of this utility model will be described below based on its overall structure.
[0028] Please see Figure 1 — Figure 8 The system includes a cleanroom 1 and an air supply device 2. The air supply device 2 is installed on the outer wall of the cleanroom 1. Return air ducts 3 and air ducts 4 are respectively installed on both sides of the air supply device 2. The ends of the air ducts 4 are respectively connected to a first air supply duct 5 and a second air supply duct 6. Multiple sets of first connecting pipes 501 and second connecting pipes 601 are respectively installed on one side of the outer wall of the first air supply ducts 5 and the second air supply ducts 6. Air guide components are installed inside the return air ducts 3 and the air ducts 4. The air guide components include a stepper motor 701. A rotating rod 7 is installed at the end of the stepper motor 701. A baffle plate 702 and a first adjusting plate 703 are respectively fixed on both sides of the rotating rod 7. A second adjusting plate 8 is provided at one end of the first adjusting plate 703. This design solves the problem that traditional cleanroom ceiling-mounted air supply duct structures require increased power to meet heating demands when delivering warm air. Cleanroom 1 has identical return air ducts 3 and ducts 4 installed on both sides. When the air supplied by the air supply device 2 is warm air, the air guide component inside duct 4 directs the warm air to the second air supply duct 6, allowing the warm air to flow from the bottom to the top of cleanroom 1 and back to the air supply device 2 via the return air duct 3 at the top. The warm air, following the natural upward movement of hot air after being delivered from the bottom, quickly fills the entire room without requiring additional power from the air conditioner, avoiding the energy waste caused by the accumulation of hot air at the top when delivering warm air using traditional ceiling-mounted air supply duct structures.
[0029] For details regarding the above embodiments, please refer to [link / reference]. Figure 5Both sides of the inner wall of one end of the air duct 4 are provided with blocking grooves 401. One end of the inner wall of the first air supply duct 5 and the second air supply duct 6 are fixed with limiting plates 502. When the air guide assembly is adjusted, one side wall of the baffle plate 702 and the second adjusting plate 8 is tightly attached to the wall of the blocking groove 401 and the limiting plate 502, respectively, so that the air guide assembly can guide the air inside the air duct 4 to the second air supply duct 6.
[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 7 and Figure 8 Two sets of sliders 704 are fixed on one side of the outer wall of the first adjusting plate 703, and two sets of sliding grooves 802 are opened on one side of the outer wall of the second adjusting plate 8. When the second adjusting plate 8 moves, the second adjusting plate 8 can slide on the outer wall of the first adjusting plate 703.
[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 7 The slider 704 is T-shaped and located in the groove 802. During the movement of the second adjusting plate 8, the T-shaped slider 704 can limit the movement direction of the second adjusting plate 8, so that the second adjusting plate 8 can slide horizontally along the wall of the first adjusting plate 703.
[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 7 Two sets of fixing plates 705 are fixed to the outer walls of the first adjusting plate 703 and the second adjusting plate 8. A spring 706 is fixedly installed on the outer wall of the fixing plate 705, and the spring 706 is always in a compressed state. During the process of the air guide assembly guiding the air inside the air duct 4, the initial state of the spring 706 is a compressed state. The spring 706 in the compressed state pushes the second adjusting plate 8 away from the first adjusting plate 7 through the fixing plate 705 fixedly connected to its end, so that the second adjusting plate 8 and the first adjusting plate 702 can be in an extended state.
[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 7 Bearings 707 are installed at both ends of the rotating rod 7. The rotating rod 7 is installed on the pipe through the bearings 707. The stepper motor 701 is fixedly installed on the outer wall of the pipe and is electrically connected to the control panel inside the clean room 1. When the stepper motor 701 drives the rotating rod 7 to rotate, the bearings 707 installed at both ends of the rotating rod 7 can support the rotating rod 7.
[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 7Four pairs of pulleys 801 are installed at one end of the second adjusting plate 8, and each pair of pulleys 801 is respectively set on both sides of the end wall of the second adjusting plate 8. When the second adjusting plate 8 rotates, the second adjusting plate 8 moves towards the first adjusting plate 703 due to the pressure of the first air supply duct 5 wall on the multiple sets of pulleys 801 at the end of the second adjusting plate 8. The installation of pulleys 801 can reduce the wear of the inner wall of the duct during the rotation adjustment of the second adjusting plate 8.
[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2 The return air duct 3 has the same pipe structure as the air duct 4, the first air supply duct 5, and the second air supply duct 6. After the air supply device 2 sends warm air into the clean room 1 from the bottom, the warm air can flow out from the top of the clean room 1.
[0036] In practical operation, the air supply device 2 delivers the cold air from the air conditioning system connected to one end to the air duct 4. When the cold air flows to the end of the air duct 4, the air guide assembly composed of the baffle plate 702, the first adjusting plate 703 and the second adjusting plate 8 guides the cold air upward to the first air supply pipe 5. The cold air flowing in the first air supply pipe 5 flows into the clean room 1 through multiple sets of first connecting pipes 501 set on one side of the first air supply pipe 5. The cold air flowing into the clean room 1 from the high point of the clean room 1 has a higher air density than the indoor air density, so the cold air flows from top to bottom in the clean room 1. Then the air in the clean room 1 flows back into the air supply device 2 through the return air pipe 3 set at the bottom of one side of the clean room 1. When warm air needs to be supplied to the cleanroom 1, personnel can first adjust the temperature of the air conditioning system connected to the air supply device 2 via the control panel inside the cleanroom 1. Simultaneously, they can control the operation of two sets of stepper motors 701 on the return air duct 3 and the air duct 4. The stepper motor 701, through a rotating rod 7 connected to its end, drives the baffle plate 702 and the first adjusting plate 703 to rotate, causing one end of the baffle plate 702 to rotate and engage with the blocking groove 401 located at the top of the inner wall of the air duct 4. When the rotating rod 7 rotates, the rotating first adjusting plate 703, through a T-shaped slider 704 fixed on its outer wall, drives the second adjusting plate 8 to rotate synchronously. When the second adjusting plate 8 rotates, the wall of the first air supply duct 5 faces the second adjusting plate... The compression of multiple sets of pulleys 801 at the end of plate 8 causes the second adjusting plate 8 to move towards the first adjusting plate 703 and compress the compression spring 706 until the second adjusting plate 8 is in a horizontal state. When the second adjusting plate 8 continues to rotate, the spring 706 in the compressed state pushes the second adjusting plate 8 away from the first adjusting plate 703 through the fixing plate 705 fixedly connected to the outer wall of the second adjusting plate 8 until one side of the outer wall of the second adjusting plate 8 is tightly fitted with the limiting plate 502 on the inner wall of the second air supply duct 6. At this point, the stepper motor 701 stops running, and the air guide assembly located inside the return air duct 3 runs in the opposite direction, so that the air inside the clean room 1 flows back to the air supply device 2 from the return air duct 3 set at the top of one side of the clean room 1.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
