Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a ventilation and dehumidification device. Background Technology

[0002] With the development of power transmission technology, power equipment is now typically located in relatively enclosed spaces such as substations and switching stations, including buildings. Moisture in the air easily condenses on power equipment, affecting its conductivity and even causing corrosion and damage to metal components.

[0003] In related technologies, dehumidification devices are typically installed to reduce the humidity in enclosed spaces. Additionally, because electrical equipment generates a large amount of heat during operation, leading to higher temperatures within enclosed spaces, substations, switch stations, and similar locations are usually equipped with ventilation systems to allow air circulation between the enclosed space and the outside, thereby reducing the temperature within the enclosed space.

[0004] However, the aforementioned dehumidification and heat dissipation methods require two different devices, which need to be installed separately, making operation cumbersome. Furthermore, existing dehumidification devices typically only have a single dehumidifying component, such as a moisture-absorbing sponge, lime, or silica gel. When the absorbent material becomes saturated, the dehumidification effect drops significantly, requiring replacement of the absorbent material or drainage of the absorbed water before resuming dehumidification, further complicating the process. Utility Model Content

[0005] Therefore, it is necessary to provide a ventilation and dehumidification device that is easy to install and has a large water absorption capacity, addressing the problems of inconvenient installation of separate ventilation and dehumidification devices and the easy saturation and frequent replacement of dehumidification components.

[0006] A ventilation and dehumidification device, comprising:

[0007] The housing is equipped with an air inlet and an exhaust outlet;

[0008] A ventilation assembly, disposed inside the housing, is used to generate an airflow from the air inlet to the air outlet;

[0009] The cylindrical body is connected to the outer wall of the shell;

[0010] A dehumidification component is located inside the cylinder and is used to convert moisture in the air into liquid water;

[0011] A water storage tank is connected to the side wall of the shell, and the water storage tank is in communication with the cylinder.

[0012] In some embodiments, the dehumidification assembly includes a first fan, a moisture-absorbing sponge, and a squeezing mechanism disposed within the cylinder. The first fan is used to generate an airflow through the moisture-absorbing sponge, and the squeezing mechanism is movably connected to the cylinder and is used to squeeze the moisture-absorbing sponge.

[0013] In some embodiments, the extrusion mechanism includes an extrusion plate, a permeable mesh plate, and a drive assembly. The moisture-absorbing sponge is disposed between the extrusion plate and the permeable mesh plate. The extrusion plate is connected to the drive assembly, which drives the extrusion plate to move relative to the permeable mesh plate, so that the extrusion plate and the permeable mesh plate extrude pressure on the moisture-absorbing sponge.

[0014] In some embodiments, the driving assembly includes a slider, a threaded rod, and a drive motor. The drive motor is connected to the cylinder. One end of the threaded rod is connected to the output shaft of the drive motor, and the other end is rotatably connected to the cylinder. The slider is sleeved on the outer periphery of the threaded rod, and the inner sidewall of the slider is threadedly connected to the threaded rod. When the threaded rod rotates, the slider moves along the length direction of the threaded rod. The extrusion plate is connected to the slider and moves with the slider.

[0015] In some embodiments, the inner wall of the cylinder is provided with a mounting groove, and the threaded rod and the drive motor are both located in the mounting groove.

[0016] In some embodiments, the surface of the extrusion plate that contacts the moisture-absorbing sponge has multiple guide grooves.

[0017] In some embodiments, the ventilation and dehumidification device further includes a corrugated pipe, one end of which is connected to the cylinder and the other end of which is connected to the water storage tank, and the cylinder and the water storage tank are connected through the corrugated pipe.

[0018] In some embodiments, the ventilation and dehumidification device further includes a mounting frame, which is an annular structure, with the cylindrical body disposed inside the mounting frame and rotatably connected to the inner sidewall of the mounting frame.

[0019] In some embodiments, the ventilation assembly includes a second fan and a heat dissipation mechanism, both of which are disposed between the air inlet and the exhaust outlet. The second fan is used to generate an airflow from the air inlet to the exhaust outlet.

[0020] In some embodiments, the ventilation assembly further includes a deflector plate disposed between the air inlet and the exhaust outlet;

[0021] The side wall of the shell is provided with a drain port, which is connected to the water storage tank, and the drain plate is provided corresponding to the drain port.

[0022] The aforementioned ventilation and dehumidification device, by placing the ventilation component inside the housing, allows gas in the sealed space to flow from the air inlet to the exhaust outlet, and finally to the outside of the sealed space, forming air circulation to reduce the temperature inside the sealed space. The dehumidification component is placed inside the cylinder, which is connected to the outer wall of the housing to form an integrated structure. The dehumidification component converts moisture in the air into liquid water to reduce the humidity in the sealed space. The liquid water converted by the dehumidification component enters the cylinder, maintaining a good dehumidification effect. The liquid water in the cylinder flows into a water storage tank for storage. The beneficial effects of this application are: placing the dehumidification component inside the cylinder can reduce the humidity of the surrounding air; the connection between the cylinder and the housing integrates the dehumidification component and the ventilation component, facilitating their assembly and disassembly; in addition, by setting up a water storage tank, compared to the case without a water storage tank, more liquid water converted by the dehumidification component can be stored, effectively reducing the frequency and complexity of drainage operations.

[0035] See Figure 1 , Figure 2 and Figure 4 , Figure 1 A schematic diagram of the overall structure of the ventilation and dehumidification device according to one embodiment of this application is shown. Figure 2 An exploded view of the internal structure of the housing 100 in one embodiment of this application is shown. Figure 4A schematic diagram of the dehumidification component 400 in one embodiment of this application is shown. An embodiment of this application provides a ventilation and dehumidification device, which includes a housing 100, a ventilation component 200, a cylinder 300, a dehumidification component 400, and a water storage tank 500. The housing 100 has an air inlet 110 and an exhaust outlet 120; the ventilation component 200 is disposed inside the housing 100 and is used to form an airflow from the air inlet 110 to the exhaust outlet 120; the cylinder 300 is connected to the outer wall of the housing 100; the dehumidification component 400 is disposed inside the cylinder 300 and is used to convert moisture in the air into liquid water; the water storage tank 500 is connected to the side wall of the housing 100 and communicates with the cylinder 300.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, preferably, the housing 100 has an airflow channel inside, which is located between the air inlet 110 and the exhaust port 120. The ventilation component 200 is located inside the airflow channel. The ventilation component 200 can be a fan, an air pump, or other devices. Under the action of the ventilation component 200, the gas outside the housing enters the housing 100 through the air inlet 110 and flows to the exhaust port 120 through the airflow channel. The gas is then discharged from the inside of the housing 100 through the exhaust port 120, thereby realizing the discharge of gas from the air inlet 110 side to the exhaust port 120 side. The dehumidification component 400 can be made of materials such as a condenser, absorbent cotton, activated carbon, or silica gel. It converts moisture in the air entering the cylinder 300 into liquid water to reduce humidity, and the liquid water is easy to collect. After absorbing a certain amount of liquid water, the dehumidification component 400 can be pressurized, centrifuged, or allowed to settle, causing the liquid water to flow out into the cylinder 300. The liquid water in the cylinder 300 then flows into the water storage tank 500 for collection. The cylinder 300 is connected to the side wall of the shell 100 for easy installation. Because the shell 100 has a ventilation component 200, air flows towards the shell 100, making it easier for the air to flow through the dehumidification component 400 inside the cylinder 300, thus improving the dehumidification effect to a certain extent.

[0037] In use, the housing 100 of this ventilation and dehumidification device is installed on the wall of a sealed space. The side of the housing 100 with the air inlet 110 faces the interior of the sealed space, and the side of the housing 100 with the exhaust outlet 120 faces the exterior of the sealed space. When the temperature inside the sealed space is too high or the air flow is poor and ventilation is required, the ventilation component 200 is activated. Air from the sealed space enters the housing 100 through the air inlet 110 and is discharged to the exterior of the sealed space through the exhaust outlet 120, thereby improving air flow and lowering the temperature inside the sealed space. The cylinder 300 is located inside the sealed space. The dehumidification component 400 inside the cylinder 300 converts the moisture in the air inside the sealed space into liquid water. The liquid water flows from the cylinder 300 into the water storage tank 500 for storage. When the liquid water in the water storage tank 500 reaches a certain level, the liquid in the water storage tank 500 is drained or the water storage tank is replaced to continue storing the liquid water converted by the dehumidification component 400.

[0038] With the above configuration, by connecting the cylinder 300 to the side wall of the housing 100, the ventilation component 200 and the dehumidification component 400 are integrated, which facilitates installation and use. The water storage tank 500 is set up to store the liquid water converted by the dehumidification component 400. Compared with setting only the dehumidification component 400, the water storage tank 500 can store more liquid water and the time interval between each drainage is longer, which can effectively reduce the frequency of drainage and reduce the cumbersomeness of drainage operation.

[0039] In some embodiments, the dehumidification assembly 400 includes a first fan 410, a moisture-absorbing sponge 420, and a squeezing mechanism 430 disposed within the cylinder 300. The first fan 410 is used to generate an airflow through the moisture-absorbing sponge 420, and the squeezing mechanism 430 is movably connected to the cylinder 300 and is used to squeeze the moisture-absorbing sponge 420.

[0040] like Figure 3 and Figure 4As shown, preferably, the surface of the cylinder 300 is provided with an air inlet 310 and an air outlet (not shown in the figure). A first fan 410 and a moisture-absorbing sponge 420 are disposed between the air inlet 310 and the air outlet. The first fan 410 is used to generate an airflow from the air inlet 310 to the air outlet. The generated airflow can flow through the moisture-absorbing sponge 420, thereby absorbing moisture in the airflow. The humidity of the air flowing through the moisture-absorbing sponge 420 is reduced, and the air is discharged from the air outlet back into the sealed space, thereby reducing the humidity of the sealed space. Since the moisture absorbed by the moisture-absorbing sponge 420 will remain inside the moisture-absorbing sponge 420, when there is too much water remaining inside the moisture-absorbing sponge 420, it will reduce the water absorption and dehumidification capacity of the moisture-absorbing sponge 420. By squeezing the moisture-absorbing sponge 420 by the squeezing mechanism 430, the liquid water inside the moisture-absorbing sponge 420 can be squeezed out, so that the moisture-absorbing sponge 420 maintains a good dehumidification effect. The liquid water squeezed out from the absorbent sponge 420 flows from the cylinder 300 into the water storage tank 500 for storage.

[0041] When this ventilation and dehumidification device is in use, the first fan 410 is activated to draw air into the cylinder 300. The air flows over the moisture-absorbing sponge 420, reducing its humidity. The lower humidity air then flows out of the outlet into the enclosed space, further reducing the overall humidity within the enclosed space. The squeezing mechanism 430 squeezes the moisture-absorbing sponge 420 at regular intervals to maintain its dehumidification effect. It should be noted that the interval between squeezing the moisture-absorbing sponge 420 by the squeezing mechanism 430 is determined based on the water storage capacity of the moisture-absorbing sponge 420. For example, if the moisture-absorbing sponge 420 reaches saturation after 5 minutes of absorption, the squeezing mechanism 430 can be set to squeeze the sponge 420 every 4 minutes to prevent saturation and reduced dehumidification effect.

[0042] With the above configuration, the first fan 410 can accelerate the airflow through the moisture-absorbing sponge 420, effectively improving the dehumidification effect. Furthermore, the squeezing mechanism 430 squeezes the moisture-absorbing sponge 420, expelling the liquid water within it. This ensures that the liquid water flows into the water storage tank 500 while maintaining a good dehumidification effect for the moisture-absorbing sponge 420.

[0043] In some embodiments, the extrusion mechanism 430 includes an extrusion plate 431, a permeable mesh plate 432, and a drive assembly 433. The moisture-absorbing sponge 420 is disposed between the extrusion plate 431 and the permeable mesh plate 432. The extrusion plate 431 is connected to the drive assembly 433. The drive assembly 433 is used to drive the extrusion plate 431 to move relative to the permeable mesh plate 432, so that the extrusion plate 431 and the permeable mesh plate 432 extrude pressure on the moisture-absorbing sponge 420.

[0044] like Figure 3 and Figure 4As shown, preferably, the moisture-absorbing sponge 420 is cylindrical according to the shape of the cylinder 300 to ensure that all gas entering the cylinder 300 passes through the moisture-absorbing sponge 420, thereby improving the dehumidification effect. A permeable mesh plate 432 is laid on the upper surface of the moisture-absorbing sponge 420, and a squeezing plate 431 is located below the moisture-absorbing sponge 420. Both the squeezing plate 431 and the permeable mesh plate 432 are circular plate-shaped according to the shape of the moisture-absorbing sponge 420 to increase the contact area with the moisture-absorbing sponge 420 and improve the squeezing effect. A driving assembly 433 is located inside the cylinder 300 and is used to drive the squeezing plate 431 closer to or further away from the moisture-absorbing sponge 420 to squeeze the moisture-absorbing sponge 420. Through the above arrangement, the squeezing plate 431 and the permeable mesh plate 432 can squeeze the moisture-absorbing sponge 420, thereby squeezing out the liquid water inside the moisture-absorbing sponge 420 and maintaining a good moisture absorption effect.

[0045] It should be noted that the permeable mesh plate 432 is provided with multiple through holes. When the extrusion plate 431 and the permeable mesh plate 432 extrude the moisture-absorbing sponge 420, the liquid water inside the moisture-absorbing sponge 420 can flow out through the through holes on the permeable mesh plate 432, thereby improving the extrusion and drainage effect and efficiency of the moisture-absorbing sponge 420.

[0046] In addition, the dehumidification assembly 400 also includes a positioning ring 440, which is located between the permeable mesh plate 432 and the first fan 410 to prevent liquid water overflowing from the moisture-absorbing sponge 420 due to the permeable mesh plate 432 from flowing into the first fan 410 and causing damage to the first fan 410. Furthermore, the positioning ring 440 has threaded holes, and the first fan 410 and the permeable mesh plate 432 are fixedly connected to the positioning ring 440 by screws. The outer wall of the positioning ring 440 abuts against the inner wall of the cylinder 300 to ensure that the first fan 410 and the permeable mesh plate 432 are not easily misaligned or shifted during use.

[0047] In some embodiments, the drive assembly 433 includes a slider 4331, a threaded rod 4332, and a drive motor 4333. The drive motor 4333 is connected to the cylinder 300. One end of the threaded rod 4332 is connected to the output shaft of the drive motor 4333, and the other end is rotatably connected to the cylinder 300. The slider 4331 is sleeved on the outer periphery of the threaded rod 4332, and the inner sidewall of the slider 4331 is threadedly connected to the threaded rod 4332. When the threaded rod 4332 rotates, the slider 4331 moves along the length direction of the threaded rod 4332. The extrusion plate 431 is connected to the slider 4331 and moves with the slider 4331.

[0048] like Figure 4As shown, preferably, the drive motor 4333 is fixedly connected to the side wall of the cylinder 300, and the threaded rod 4332 is rotatably connected to the side wall of the cylinder 300. The drive motor 4333 drives the threaded rod 4332 to rotate along its own central axis. The slider 4331 is threadedly connected to the threaded rod 4332, allowing the slider 4331 to move up and down along the length of the threaded rod 4332 according to the rotation direction of the threaded rod 4332. The extrusion plate 431 is fixedly connected to the slider 4331, allowing the slider 4331 to drive the extrusion plate 431 to move along the length of the threaded rod 4332, so that the extrusion plate 431 can approach or move away from the moisture-absorbing sponge 420 to compress the moisture-absorbing sponge 420. With the above arrangement, the extrusion plate 431 can be driven to approach or move away from the moisture-absorbing sponge 420 to compress the moisture-absorbing sponge 420.

[0049] In some embodiments, the inner wall of the cylinder 300 is provided with a mounting groove (not shown in the figure), and the threaded rod 4332 and the drive motor 4333 are both located in the mounting groove.

[0050] like Figure 3 As shown, preferably, the mounting groove is opened on the inner side wall of the cylinder 300, and the threaded rod 4332 and the drive motor 4333 are set in the mounting groove. By setting the mounting groove, the installation space inside the cylinder 300 can be increased.

[0051] In some embodiments, the sidewall thickness of the cylinder 300 is small, and the depth of the mounting groove formed on the inner sidewall of the cylinder 300 is insufficient to accommodate the drive motor 4333 and the threaded rod 4332. Therefore, as Figure 3 As shown, in some embodiments, a mounting shell 320 is provided on the outer side wall of the cylinder 300 at the position corresponding to the mounting groove. The side wall of the mounting shell 320 is connected to the outer side wall of the cylinder 300. The interior of the mounting shell 320 is provided with a mounting cavity. The drive motor 4333 and the threaded rod 4332 are located in the mounting cavity and are connected to the inner side wall of the mounting shell 320 to facilitate the installation of the threaded rod 4332 and the drive motor 4333.

[0052] In some embodiments, the surface of the extrusion plate 431 that contacts the moisture-absorbing sponge 420 is provided with a plurality of guide grooves 4311.

[0053] like Figure 4As shown, preferably, the extrusion plate 431 has multiple guide grooves 4311. When the extrusion plate 431 extrudes the moisture-absorbing sponge 420, the liquid water squeezed out from the lower surface of the moisture-absorbing sponge 420 flows out through the guide grooves 4311. With the above arrangement, when the extrusion plate 431 extrudes the moisture-absorbing sponge 420, some of the liquid water inside the moisture-absorbing sponge 420 can be discharged through the guide grooves 4311, which can increase the drainage volume of the moisture-absorbing sponge 420 each time it is extruded, thus improving the extrusion drainage effect. Moreover, the larger the total area of ​​the guide grooves 4311, the better the extrusion drainage effect.

[0054] In some embodiments, the ventilation and dehumidification device further includes a corrugated pipe 600, one end of which is connected to the cylinder 300 and the other end of which is connected to the water storage tank 500. The cylinder 300 and the water storage tank 500 are connected through the corrugated pipe 600.

[0055] like Figure 1 and Figure 3 As shown, preferably, the surface of the cylinder 300 is also provided with drainage holes (not shown in the figure). The cylinder 300 is connected to the water storage tank 500 through a corrugated pipe 600. When this ventilation and dehumidification device is installed, the vertical height of the cylinder 300 is higher than the height of the water storage tank 500. Under the action of gravity, the liquid water in the cylinder 300 flows into the corrugated pipe 600 through the drainage holes and then flows into the lower-height water storage tank 500 along the corrugated pipe 600. By setting the corrugated pipe 600, the liquid water in the cylinder 300 can flow into the water storage tank 500. In addition, the corrugated pipe 600 can be extended or retracted according to the distance between the cylinder 300 and the water storage tank 500 during actual installation to adjust the length of the corrugated pipe 600, which facilitates the connection between the cylinder 300 and the water storage tank 500.

[0056] In some embodiments, the ventilation and dehumidification device further includes a mounting frame 700, which is an annular structure. The cylinder 300 is disposed inside the mounting frame 700 and is rotatably connected to the inner sidewall of the mounting frame 700.

[0057] like Figure 1 and Figure 3As shown, preferably, the mounting bracket 700 is a rectangular frame, with one side of the mounting bracket 700 fixedly connected to the outer wall of the housing 100. The mounting bracket 700 has a ring-shaped structure, and the cylinder 300 is disposed inside the ring-shaped structure to protect the cylinder 300 from impact damage. The cylinder 300 is rotatably connected to the mounting bracket 700, allowing the cylinder 300 to rotate and change its orientation. It should be noted that in some usage scenarios, when the cylinder 300 faces the wall where it is installed, the wall obstructs air from easily entering the cylinder 300, resulting in poor dehumidification. Rotating the cylinder 300 avoids obstruction and ensures better dehumidification. In addition, during use, rotating the cylinder 300 continuously changes its orientation, allowing air from multiple directions to enter the cylinder 300 for dehumidification, which can improve the dehumidification effect to a certain extent.

[0058] Furthermore, in some embodiments, the outer wall of the cylinder 300 is provided with a pivot 330, and the cylinder 300 is rotatably connected to the mounting bracket 700 via the pivot 330. For example... Figure 1 and Figure 3 As shown, preferably, there are two rotating shafts 330, which are respectively connected to opposite sides of the outer wall of the cylinder 300. The cylinder 300 is rotatably connected to the mounting frame 700 through the rotating shafts 330, so that the cylinder 300 can rotate to adjust its orientation.

[0059] Furthermore, the mounting bracket 700 is equipped with a limiting structure, which can be a limiting groove, a limiting protrusion, etc. By setting the limiting structure, the rotation angle of the cylinder 300 is limited to 120°, preventing excessive rotation angle of the cylinder 300 from causing backflow of liquid water inside the cylinder 300. For ease of understanding, as... Figure 1 As shown, the cylinder 300 is set vertically. The liquid water absorbed and converted by the dehumidification component 400 flows downward to the water storage tank 500 under the action of gravity. If the cylinder 300 is rotated 90° to be placed horizontally, the liquid water in the cylinder 300 will flow back to the dehumidification component 400, which will reduce the dehumidification effect of the dehumidification component 400. Therefore, by setting a limiting structure, the rotation angle of the cylinder 300 can be effectively avoided to prevent the liquid water from flowing back.

[0060] In some embodiments, the ventilation assembly 200 includes a second fan 210 and a heat dissipation mechanism 220, both of which are disposed between the air inlet 110 and the exhaust outlet 120. The second fan 210 is used to generate an airflow from the air inlet 110 to the exhaust outlet 120.

[0061] like Figure 1 and Figure 2As shown, preferably, the second fan 210 and the heat dissipation mechanism 220 are both disposed between the air inlet 110 and the exhaust port 120. The airflow generated by the second fan 210 flows through the heat dissipation mechanism 220, which can cool the flowing gas to ensure that the temperature of the gas discharged from the exhaust port 120 is low, thereby reducing the impact of the overheated exhaust gas on the environment around the exhaust port 120.

[0062] Furthermore, the heat dissipation mechanism 220 can be made of liquid cooling or thermal silicone, as long as it can cool the flowing gas.

[0063] In some embodiments, the ventilation assembly 200 further includes a deflector plate 230 disposed between the air inlet 110 and the exhaust outlet 120;

[0064] The side wall of the shell 100 is provided with a drain port (not shown in the figure), which is connected to the water storage tank 500, and the drain plate 230 is set corresponding to the drain port.

[0065] like Figure 1 , Figure 2 and Figure 5 As shown, preferably, the air intake plate 230 is located between the air inlet 110 and the exhaust port 120. Airflow from the air inlet 110 to the exhaust port 120 can pass through the air intake plate 230. The air intake plate 230 is a corrugated metal plate to increase the contact area with the air. When warmer air flows through the air intake plate 230, moisture in the air condenses on the surface of the air intake plate 230, thus preventing moisture from entering the internal structures of the housing 100 (such as the liquid cooling device mentioned above). It should be noted that although the dehumidification component 400 can absorb moisture from the air, it cannot completely remove it. Therefore, by setting the air intake plate 230, the moisture content of the air entering the housing 100 can be further reduced. The water storage tank 500 is located below the housing 100, and the air intake port is opened on the lower surface of the housing 100. The corresponding air intake port of the air intake plate 230 allows the liquid water condensed on the air intake plate 230 to fall into the water storage tank 500 under gravity. The above-mentioned settings can prevent excessive humidity in the air entering the housing 100, thus avoiding damage to the devices inside the housing 100. Furthermore, in some cases, this ventilation and dehumidification device cannot directly exhaust the gas in the enclosed space to the outside, such as when multiple switch stations are located adjacent to each other or when a larger enclosed space is located outside the enclosed space. In such cases, excessively high humidity in the exhausted gas can be prevented from unnecessarily affecting the gas exhaust location.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
