Description
Technical Field
[0001] This utility model relates to the field of dehumidifier technology, specifically to an energy-saving constant temperature and humidity dehumidifier. Background Technology
[0002] Temperature-regulating dehumidifiers, also known as constant-temperature dehumidifiers, are similar to air conditioners, consisting of an indoor unit and an outdoor unit. However, compared to traditional air conditioners, which only have an evaporator in their indoor unit for temperature regulation, temperature-regulating dehumidifiers have both a condenser and an evaporator. They can not only regulate temperature but also dehumidify, making them a highly efficient and energy-saving dehumidification method. They are widely used in national defense projects, civil defense projects, the petrochemical industry, subway stations, laboratories, telecommunications equipment rooms, archives, food processing rooms, pharmaceutical or film workshops, grain and timber processing, and other places requiring dehumidification, drying, and temperature control in high-humidity spaces.
[0003] Existing energy-saving constant temperature and humidity dehumidifiers typically use dust filters for dust prevention during operation. Over time, impurities accumulate and clog the dust filter, requiring cleaning. Common cleaning methods include manual disassembly and cleaning or automatic cleaning. Automatic cleaning usually involves a cleaning structure driven by actuators such as cylinders, electric cylinders, hydraulic cylinders, or motors to clean the dust filter, or using fluid backflushing or rinsing in conjunction with the cleaning structure. However, this requires the cleaning structure to run continuously for a period of time, resulting in high energy consumption. Furthermore, the constant relative movement between the cleaning structure and the dust filter causes wear on the brushes, scrapers, or the dust filter itself, resulting in a large amount of debris and lint falling into the constant temperature and humidity dehumidifier. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide an energy-saving constant temperature and humidity dehumidifier to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving constant temperature and humidity dehumidifier, comprising a temperature-regulating dehumidifier body, wherein air ducts are fixed on the outer surface of the temperature-regulating dehumidifier body, and an air outlet is provided at the upper back of the air ducts, and an air inlet is provided at the lower back of the air ducts; a first air outlet and a second air outlet are respectively provided on both sides of the air ducts, and dustproof nets are provided on both sides inside the air ducts; a first servo motor is installed above the outer surface of the air ducts, and a worm gear reducer is connected to the output end of the first servo motor, and a guide plate is connected to the output end of the worm gear reducer, and sealing strips are connected to both sides of the guide plate; a second servo motor and a limiting block are provided on both sides of the outer surface of the air ducts, and baffles are connected to the output ends of the two second servo motors; support frames are fixed on both sides of the outer surface of the temperature-regulating dehumidifier body, and filter boxes are connected to the top of the two support frames.
[0006] By adopting the above technical solution, assuming that the first air outlet is connected to the air inlet and the second air outlet is connected to the air outlet through the baffle and sealing strip, the humid indoor air will enter the temperature-regulating dehumidifier through the first air outlet and the air inlet for dehumidification and temperature regulation. Afterwards, the dry air returns to the room through the air outlet and the second air outlet, thus ensuring constant temperature and humidity indoors. After the first servo motor starts, its output end drives the baffle and sealing strip to rotate counterclockwise by 90 degrees through a worm gear reducer. At this time, the first air outlet is connected to the air outlet, and the second air outlet is connected to the air inlet. This facilitates the airflow generated by the temperature-regulating dehumidifier body to continuously backflush the dust filter blocking the first air outlet, and the worm gear reducer self-locks and limits the baffle. The output end of the second servo motor drives the baffle to rotate upward by 90 degrees, thereby blocking the first air outlet and causing the backflushing airflow to move downwards into the filter box. The airflow then passes through the filter box and returns to the room, while the backflushing airflow... Dust is trapped and stored in the filter box, reducing the occurrence of dust being blown out and causing dust pollution due to backflushing. After backflushing, the output of the second servo motor reverses and drives the baffle to rotate downwards by 90 degrees, allowing the airflow to be discharged in a straight line, thereby reducing exhaust resistance. When the dust screen in the second air outlet is blocked, the output of the first servo motor simply drives the guide plate and sealing strip to rotate clockwise by 90 degrees through the worm gear reducer, connecting the first air outlet with the air inlet and the second air outlet with the air outlet, thereby backflushing and removing dust from the dust screen in the second air outlet. The output of the second servo motor drives the baffle to rotate upwards by 90 degrees, thereby blocking the second air outlet and causing the backflushing airflow to move downwards into the filter box. After that, the airflow passes through the filter box and returns to the room. When there are many impurities in the filter box, the operator can rotate the limit block upwards to stop limiting the filter box. Then the filter box can be removed from the support frame for cleaning. After cleaning, the filter box is put back and the limit block is rotated downwards to limit the filter box.
[0007] Furthermore, a flow sensor is installed inside the air inlet.
[0008] By adopting the above technical solution, when the dust filter becomes clogged, the staff can manually start the first and second servo motors, or the flow sensor can measure the airflow. If the airflow through the air inlet is significantly reduced, it means that the dust filter is clogged. At this time, the flow sensor sends an electrical signal to the control panel, thereby automatically starting the first and second servo motors.
[0009] Furthermore, the guide plate is inclined and rotatably connected to the air duct.
[0010] By adopting the above technical solution, after the first servo motor starts, the output end drives the guide plate and sealing strip to rotate counterclockwise by 90 degrees through the worm gear reducer. At this time, the first air outlet is connected to the air outlet, and the second air outlet is connected to the air inlet. This facilitates the airflow generated by the main body of the temperature-regulating dehumidifier to continuously backwash and remove dust from the dustproof screen blocked in the first air outlet, and the guide plate is limited by the self-locking of the worm gear reducer.
[0011] Furthermore, the baffle is rotatably connected to the air duct, and the baffle is located above the filter box.
[0012] By adopting the above technical solution, the output end of the second servo motor drives the baffle to rotate upward by 90 degrees, thereby blocking the first air outlet and causing the backflow airflow to move downward into the filter box. After that, the airflow passes through the filter box and returns to the room, while the dust that is backflowed is intercepted and stored by the filter box, reducing the phenomenon of dust being blown out and causing dust pollution due to backflow. After the backflow is completed, the output end of the second servo motor reverses and drives the baffle to rotate downward by 90 degrees, so that the airflow can be discharged in a straight line, thereby reducing the exhaust resistance.
[0013] Furthermore, the sealing strip is made of EPDM rubber, glass fiber reinforced PTFE, or silicone rubber.
[0014] By adopting the above technical solutions, EPDM rubber is preferred, followed by glass fiber reinforced PTFE, and silicone rubber is selected for special scenarios. EPDM rubber has good resistance to damp heat, avoiding hydrolysis and expansion of the sealing strip caused by humid air. It also has excellent static sealing performance, and since the deflector is not a frequently moving part, it has a long service life and high cost-effectiveness. Glass fiber reinforced PTFE is hydrophobic and unaffected by humid air. It also has a low coefficient of friction, making it suitable for scenarios with severe dust and high deflector movement frequency. It also has good sealing performance and a long service life, but its cost is relatively high. Silicone rubber is more suitable for high-temperature scenarios and its cost is relatively low.
[0015] Furthermore, the limiting block is rotatably connected to the air duct via a damping shaft, and the filter box abuts against the limiting block.
[0016] By adopting the above technical solution, after cleaning, the staff put the filter box back and rotated the limiting block downward to limit the filter box.
[0017] Furthermore, the filter box is detachably connected to the support frame, and the support frame has a "U" shaped cross-section.
[0018] By adopting the above technical solution, when there are many impurities in the filter box, the staff can rotate the limit block upward to stop the filter box from being restricted, and then the filter box can be removed from the support frame for cleaning.
[0019] Furthermore, a control panel is installed above the outer surface of the main body of the temperature-regulating dehumidifier, and the main body of the temperature-regulating dehumidifier, the first servo motor, the flow sensor and the second servo motor are all electrically connected to the control panel.
[0020] By adopting the above technical solution, when the dust filter becomes clogged, the staff can manually start the first and second servo motors, or the flow sensor can measure the airflow. If the airflow through the air inlet is significantly reduced, it means that the dust filter is clogged. At this time, the flow sensor sends an electrical signal to the control panel, thereby automatically starting the first and second servo motors.
[0021] Furthermore, a bracket is fixed to the top of the dustproof net, and the bracket is detachably connected to the air duct by bolts.
[0022] By adopting the above technical solution, when the dustproof net needs to be replaced, the staff removes the bolts on the top of the bracket and then takes the bracket out of the air duct, thereby removing the dustproof net from the air duct. After that, the staff inserts the new bracket and dustproof net into the air duct and limits them with bolts.
[0023] In summary, the present invention has the following main advantages:
[0024] 1. This utility model, through the arrangement of an air duct, a first servo motor, a worm gear reducer, a guide plate, a sealing strip, a first air outlet, and a second air outlet, allows for efficient dust removal when the dust filter becomes clogged. When this occurs, the output of the first servo motor drives the guide plate and sealing strip to rotate counterclockwise by 90 degrees via the worm gear reducer. At this point, the first air outlet connects to the air outlet, while the second air outlet connects to the air inlet. This facilitates continuous backflushing and dust removal of the clogged dust filter in the first air outlet by the airflow generated by the main body of the temperature-regulating dehumidifier. The worm gear reducer also self-locks and limits the guide plate. When the dust filter in the second air outlet becomes clogged, the output of the first servo motor simply drives the guide plate and sealing strip to rotate clockwise by 90 degrees via the worm gear reducer, connecting the first air outlet to the air inlet and the second air outlet to the air outlet, thus backflushing and removing dust from the dust filter in the second air outlet. The clogged dust filter is cleared by the airflow of the main body of the temperature-regulating dehumidifier itself, eliminating the need for a continuous cleaning structure and resulting in energy savings.
[0025] 2. This utility model, through the arrangement of a second servo motor, a baffle, a support frame, a filter box, and a limiting block, allows the output end of the second servo motor to drive the baffle to rotate upward 90 degrees before backflushing, thereby blocking the first or second air outlet and causing the backflushing airflow to move downward into the filter box. The airflow then passes through the filter box and returns to the room, while the dust that has been backflushed is intercepted and stored in the filter box, reducing the occurrence of dust being blown out and causing dust pollution. After backflushing, the output end of the second servo motor reverses and drives the baffle to rotate downward 90 degrees, allowing the airflow to be discharged in a straight line, thereby reducing exhaust resistance. When there are many impurities in the filter box, the limiting block can be rotated upward to stop limiting the filter box. The filter box can then be removed from the support frame for cleaning. After cleaning, the filter box is placed back and the limiting block is rotated downward to limit the filter box, thus reducing dust pollution. Attached Figure Description

[0031] 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.
[0032] The embodiments of this utility model will be described below based on its overall structure.
[0033] Example 1:
[0034] An energy-saving dehumidifier with constant temperature and humidity, such as Figures 1-4As shown, the device includes a temperature-regulating dehumidifier body 1. Air ducts 3 are fixed to the outer surface of the body 1. An air outlet 10 is located on the upper back of the air duct 3, and an air inlet 8 is located on the lower back of the air duct 3. A flow sensor 9 is installed inside the air inlet 8. A first air vent 11 and a second air vent 12 are respectively located on both sides of the air duct 3. Dust filters 18 are installed on both sides inside the air duct 3. Assuming that the first air vent 11 is connected to the air inlet 8 and the second air vent 12 is connected to the air outlet 10 by the baffle plate 6 and sealing strip 7, humid indoor air will enter the dehumidifier through the first air vent 11 and the air inlet 8 for dehumidification and temperature regulation. Dry air will then return to the room through the air outlet 10 and the second air vent 12, thus ensuring constant temperature and humidity indoors. When the dust filter 18 becomes blocked, the flow sensor 9 measures a significant reduction in the flow rate at the air inlet 8. At this time, the flow sensor 9 sends a signal to the control unit... Panel 2 sends an electrical signal, thereby automatically turning on the first servo motor 4 and the second servo motor 13. The first servo motor 4 is installed above the outer surface of the air duct 3. The output end of the first servo motor 4 is connected to a worm gear reducer 5. The output end of the worm gear reducer 5 is connected to a guide plate 6. The guide plate 6 is tilted and rotatably connected to the air duct 3. Both sides of the guide plate 6 are connected to sealing strips 7. The sealing strips 7 are made of EPDM rubber, glass fiber reinforced PTFE, or silicone rubber. After the first servo motor 4 starts, the output end drives the guide plate 6 and sealing strips 7 to rotate counterclockwise by 90 degrees through the worm gear reducer 5. At this time, the first air outlet 11 is connected to the air outlet 10, and the second air outlet 12 is connected to the air inlet 8. This facilitates the continuous backwashing and dust removal of the dustproof net 18 blocked in the first air outlet 11 by the airflow generated by the temperature-regulating dehumidifier body 1. The worm gear reducer 5 self-locks and limits the guide plate 6.A second servo motor 13 and a limiting block 17 are provided on both sides of the outer surface of the air duct 3. The limiting block 17 is rotatably connected to the air duct 3 via a damping shaft. The output ends of the two second servo motors 13 are connected to baffles 14, which are rotatably connected to the air duct 3. Support frames 15 are fixed on both sides of the outer surface of the temperature-regulating dehumidifier body 1. Filter boxes 16 are connected to the top of the two support frames 15. The baffles 14 are located above the filter boxes 16. The filter boxes 16 abut against the limiting blocks 17. The filter boxes 16 are detachably connected to the support frames 15. The support frame 15 has a U-shaped cross-section. The output ends of the second servo motors 13 drive the baffles 14 to rotate upwards by 90 degrees, thereby blocking the first air outlet 11. The backflow air moves downwards into the filter box 16, then returns to the room. The dust that is backflowed is trapped and stored in the filter box 16, reducing the likelihood of dust being blown out and causing dust pollution. After backflow, the output of the second servo motor 13 reverses, driving the baffle 14 to rotate downwards by 90 degrees, allowing the airflow to exit in a straight line and reducing exhaust resistance. When there are many impurities in the filter box 16, the operator can rotate the limit block 17 upwards to stop the filter box 16 from being locked. The filter box 16 can then be removed from the support frame 15 for cleaning. After cleaning, the filter box 16 is returned to its original position, and the limit block 17 is rotated downwards to lock the filter box 16.
[0035] See Figures 1-4 In the above embodiment, a control panel 2 is installed above the outer surface of the temperature-controlled dehumidifier body 1. The temperature-controlled dehumidifier body 1, the first servo motor 4, the flow sensor 9, and the second servo motor 13 are all electrically connected to the control panel 2. When the dust filter 18 is blocked, the operator can manually turn on the first servo motor 4 and the second servo motor 13, or the flow sensor 9 can measure the airflow. If the airflow through the air inlet 8 is significantly reduced, it means that the dust filter 18 is blocked. At this time, the flow sensor 9 sends an electrical signal to the control panel 2, thereby automatically turning on the first servo motor 4 and the second servo motor 13.
[0036] Example 2:
[0037] Based on the above embodiment 1, the following settings are made to facilitate the replacement of the dustproof net 18.
[0038] See Figures 1-3 In the above embodiment, a bracket 19 is fixed to the top of the dustproof net 18. The bracket 19 is detachably connected to the air duct 3 by bolts. When the dustproof net 18 needs to be replaced, the staff removes the bolts on the top of the bracket 19 and takes the bracket 19 out of the air duct 3, thereby taking the dustproof net 18 out of the air duct 3. After that, the staff inserts the new bracket 19 and the dustproof net 18 into the air duct 3 and limits them with bolts.
[0039] The implementation principle of this utility model is as follows: First, the staff can turn on the main body 1 of the temperature-regulating dehumidifier through the control panel 2. Assuming that at this time, the first air outlet 11 is connected to the air inlet 8 through the baffle plate 6 and the sealing strip 7, and the second air outlet 12 is connected to the air outlet 10, the indoor humid air will enter the temperature-regulating dehumidifier through the first air outlet 11 and the air inlet 8 for dehumidification and temperature regulation. After that, the dry air returns to the room through the air outlet 10 and the second air outlet 12, thereby ensuring constant temperature and humidity in the room.
[0040] When the dust filter 18 becomes clogged, the staff can manually start the first servo motor 4 and the second servo motor 13, or the flow sensor 9 can measure the airflow. If the airflow through the air inlet 8 is significantly reduced, it means that the dust filter 18 is clogged. At this time, the flow sensor 9 sends an electrical signal to the control panel 2, thereby automatically starting the first servo motor 4 and the second servo motor 13.
[0041] After the first servo motor 4 starts, its output end drives the guide plate 6 and sealing strip 7 to rotate counterclockwise by 90 degrees through the worm gear reducer 5. At this time, the first air outlet 11 is connected to the air outlet 10, and the second air outlet 12 is connected to the air inlet 8. This facilitates the airflow generated by the temperature-regulating dehumidifier body 1 to continuously backwash the dust filter 18 blocked in the first air outlet 11 and remove dust. The worm gear reducer 5 self-locks and limits the guide plate 6. The output end of the second servo motor 13 drives the baffle 14 to rotate upward by 90 degrees, thereby blocking the first air outlet 11 and causing the backwash airflow to move downward into the filter box 16. After that, the airflow passes through the filter box 16 and returns to the room. The dust that is backwashed is intercepted and stored by the filter box 16, reducing the phenomenon of dust being blown out and causing dust pollution due to backwash. After the backwash is completed, the output end of the second servo motor 13 reverses and drives the baffle 14 to rotate downward by 90 degrees, so that the airflow can be discharged in a straight line, thereby reducing the exhaust resistance.
[0042] When the dust filter 18 inside the second air vent 12 is blocked, the output end of the first servo motor 4 drives the guide plate 6 and the sealing strip 7 to rotate 90 degrees clockwise through the worm gear reducer 5, so that the first air vent 11 is connected to the air inlet 8 and the second air vent 12 is connected to the air outlet 10, thereby backflushing the dust filter 18 inside the second air vent 12 to remove dust. The output end of the second servo motor 13 drives the baffle 14 to rotate 90 degrees upward, thereby blocking the second air vent 12 and causing the backflushing airflow to move downward and enter the filter box 16. After that, the airflow passes through the filter box 16 and returns to the room.
[0043] When there are many impurities in the filter box 16, the operator can rotate the limit block 17 upward to stop limiting the filter box 16. Then the filter box 16 can be removed from the support frame 15 for cleaning. After cleaning, the operator puts the filter box 16 back and rotates the limit block 17 downward to limit the filter box 16.
[0044] When the dust screen 18 needs to be replaced, the staff removes the bolts on the top of the bracket 19 and then removes the bracket 19 from the air duct 3, thereby removing the dust screen 18 from the air duct 3. After that, the staff inserts the new bracket 19 and dust screen 18 into the air duct 3 and limits them with bolts.
