Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, specifically a speed control device for a wall-mounted dehumidifier fan. Background Technology

[0002] Wall-mounted dehumidifiers are used in specific environments, primarily around pool edges or on walls, requiring them to be compact. Therefore, wall-mounted dehumidifiers with adjustable speeds have not yet been available. However, with advancements in science and technology, the size of existing fans and their speed controllers has been significantly reduced, now meeting the specific requirements of wall-mounted dehumidifiers.

[0003] Existing wall-mounted dehumidifiers use AC fixed-speed fans, meaning their airflow and speed remain constant under all conditions. This means the fan energy consumption cannot be adjusted or changed according to environmental conditions, causing significant inconvenience and resource waste during use. Therefore, we propose a fan speed control device for wall-mounted dehumidifiers. Utility Model Content

[0004] The purpose of this utility model is to provide a fan speed control device for a wall-mounted dehumidifier to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wall-mounted dehumidifier fan speed control device, comprising a controller, a temperature and humidity sensor, and a fan motor. The temperature and humidity sensor is used to collect indoor temperature and humidity data. The temperature and humidity sensor is electrically connected to the controller. The controller is equipped with a data processing module for converting the temperature and humidity data collected by the temperature and humidity sensor into electrical signals. The output end of the data processing module is electrically connected to a signal transmission module. The signal transmission module is used to transmit the temperature and humidity data as electrical signals. The output end of the signal transmission module is electrically connected to a frequency converter driver that drives the fan motor to rotate. The frequency converter driver receives the electrical signals transmitted by the signal transmission module and adjusts them to the output power frequency. The frequency converter driver drives the fan motor to rotate.

[0006] Furthermore, it also includes a housing, on which an air inlet is provided and on the top of the housing an air outlet is provided, and the temperature and humidity sensor is installed at the air inlet.

[0007] Furthermore, one side of the housing is mounted to the wall via a locking mechanism, and the housing is provided with a locking mechanism to prevent the housing from disengaging from the initial positioning mechanism.

[0008] Furthermore, the preliminary positioning mechanism includes a connecting frame, a fixing frame, a first mounting plate, a mounting groove, a limiting block, and a baffle. The back of the housing is fixedly connected to a "U"-shaped fixing frame via two sets of connecting frames. Multiple sets of mounting grooves are provided on the first mounting plate. A limiting block that is inserted into the fixing frame is fixedly installed on one side of the first mounting plate via a second mounting plate. A baffle that fits against the housing is fixedly installed on one side of the limiting block.

[0009] Furthermore, the locking mechanism includes a hidden groove, a connecting rod, a connecting piece, a locking rod, and a locking groove. The housing has a hidden groove, and a connecting rod inserted into the hidden groove is fixedly installed on one side of the connecting piece. The fixing frame and the limiting block both have locking grooves, and a locking rod inserted into the locking groove is fixedly connected to one side of the connecting piece.

[0010] Furthermore, the U-shaped fixing frame is provided with a clearance groove, and multiple sets of support columns are fixedly installed on one side of the housing. A ball bearing is rotatably connected to one side of the support column.

[0011] Compared with the prior art, the present invention has the following advantages: The temperature and humidity sensor of the present invention is installed on the air inlet of the housing, which can monitor the temperature and humidity of the external environment in real time and feed the temperature and humidity data back to the data processing module inside the controller. Then, the controller can calculate the appropriate control signal based on the temperature and humidity signal fed back by the temperature and humidity sensor and send it to the frequency converter driver.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a wall-mounted dehumidifier fan speed control device, including a controller 1, a temperature and humidity sensor 3, and a fan motor 6. The temperature and humidity sensor 3 is used to collect indoor temperature and humidity data. The temperature and humidity sensor 3 is electrically connected to the controller 1. The controller 1 is equipped with a data processing module 2 for converting the temperature and humidity data collected by the temperature and humidity sensor 3 into electrical signals. The output end of the data processing module 2 is electrically connected to a signal transmission module 4. The signal transmission module 4 is used to transmit the temperature and humidity data as electrical signals. The output end of the signal transmission module 4 is electrically connected to a frequency converter 5 that drives the fan motor 6 to rotate. The frequency converter 5 receives the electrical signals transmitted by the signal transmission module 4 and adjusts them to the output power frequency. The frequency converter 5 drives the fan motor 6 to rotate. The output end of the controller 1 is electrically connected to an evaporator 7 and a condenser 8. The device also includes a housing 9. The housing 9 has an air inlet 11 and an air outlet 10 on its top. The temperature and humidity sensor 3 is installed at the air inlet 11.

[0020] The temperature and humidity sensor 3 is installed on the air inlet 11 of the housing 9. It can monitor the temperature and humidity of the external environment in real time and feed the temperature and humidity data back to the data processing module 2 inside the controller 1. Then, the controller 1 can calculate the appropriate control signal based on the temperature and humidity signal fed back by the temperature and humidity sensor 3 and send it to the frequency converter 5. The frequency converter 5 can then accurately adjust the power frequency output to the fan motor 6, thereby achieving precise adjustment of the fan motor 6 speed. This setting can quickly and stably respond to the speed change demand, reduce overshoot and adjustment time, and improve energy utilization to a certain extent, achieving the effect of energy saving. When air passes through the evaporator 7, the refrigerant in the evaporator 7 will absorb heat from the air, causing the air temperature to drop. As the temperature decreases, the water vapor in the air reaches its saturation point and begins to condense into water. Since the air is cooled below its dew point temperature, the water vapor in it condenses into liquid water droplets that adhere to the surface of the evaporator 7. Subsequently, this moisture is collected and discharged from the machine, thus achieving the dehumidification effect. The condenser 8 is installed so that the air after being cooled and dehumidified by the evaporator 7 passes through the condenser 8. During this process, the condenser 8 releases the heat previously absorbed in the evaporator 7 into the air, causing the treated air to warm up again. This not only helps to keep the indoor temperature from dropping significantly due to the dehumidification process, but also helps to improve the dehumidification efficiency, because warm air can hold more moisture, thus allowing for a more efficient circulation dehumidification process.

[0021] During speed regulation, the data processing module 2 in controller 1 employs a PID control algorithm combined with fuzzy logic control, enabling it to respond quickly and stably to speed changes, reducing overshoot and settling time, and improving speed regulation accuracy. Simultaneously, the frequency converter driver 5 utilizes a high-efficiency power module, reducing iron and copper losses in the fan motor during speed regulation, improving energy utilization, and achieving energy savings.

[0022] Please see Figure 1 and Figure 2 One side of the housing 9 is mounted to the wall via a locking mechanism 12, and the housing 9 is provided with a locking mechanism 12 to prevent the housing 9 from separating from the preliminary positioning mechanism 13.

[0023] The initial positioning mechanism 13, which is set during the installation of the housing 9, can complete the initial installation of the housing 9. The locking mechanism 12, which is set subsequently, can prevent the housing 9 and the initial positioning mechanism 13 from misaligning and disengaging, and prevent the housing 9 from falling off during use. In addition, this installation method of the housing 9 can facilitate disassembly and maintenance when the housing 9 is damaged.

[0024] Please see Figure 2 , Figure 3 and Figure 4 The preliminary positioning mechanism 13 includes a connecting frame 14, a fixing frame 15, a first mounting plate 16, a mounting groove 17, a limiting block 18, and a baffle 19. The back of the housing 9 is fixedly connected to a "U"-shaped fixing frame 15 through two sets of connecting frames 14. The first mounting plate 16 has multiple sets of mounting grooves 17. A limiting block 18 that is inserted into the fixing frame 15 is fixedly installed on one side of the first mounting plate 16 through a second mounting plate 26. A baffle 19 that fits against the housing 9 is fixedly installed on one side of the limiting block 18.

[0025] During the installation of the first mounting plate 16, expansion bolts are used to pass through the mounting groove 17 to install the first mounting plate 16 on the wall mounting position. Then, the fixing frame 15 behind the housing 9 is inserted into the limiting block 18 and the baffle 19. The limiting block 18 can then be inserted into the fixing frame 15 to install the housing 9, while the baffle 19 can contact one side of the housing 9 to prevent the housing 9 from tilting after installation.

[0026] Please see Figure 2 , Figure 3 and Figure 4 The locking mechanism 12 includes a hidden groove 20, a connecting rod 21, a connecting piece 22, a locking rod 23, and a locking groove 24. The housing 9 has a hidden groove 20. A connecting rod 21 with a rectangular cross-section is fixedly installed on one side of the connecting piece 22 and inserted into the hidden groove 20. The fixed frame 15 and the limiting block 18 both have locking grooves 24. A locking rod 23 inserted into the locking groove 24 is fixedly connected to one side of the connecting piece 22.

[0027] Once the housing 9 is initially positioned, the connecting rod 21 is inserted into the hidden groove 20, and then the connecting rod 21 is moved along the inside of the hidden groove 20. This allows the locking rod 23 to be inserted into the locking groove 24, thus completing the further locking of the fixing frame 15 and the limiting block 18.

[0028] Please see Figure 2 , Figure 3 and Figure 4 The U-shaped fixing frame 15 has a clearance groove 25. Multiple sets of support columns 27 are fixedly installed on one side of the housing 9. A ball bearing 28 is rotatably connected to one side of the support column 27. The clearance groove 25 on the fixing frame 15 can facilitate the installation and fixing of the fixing frame 15 and the limiting block 18. The ball bearing 28 can facilitate the housing 9 to contact the wall and move downward. The ball bearing 28 can support the housing 9 and prevent the housing 9 from shifting after installation.

[0029] In use, firstly, the temperature and humidity sensor 3 is installed on the air inlet 11 of the housing 9. It can monitor the temperature and humidity of the external environment in real time and feed the temperature and humidity data back to the data processing module 2 inside the controller 1. Then, the controller 1 can calculate the appropriate control signal based on the temperature and humidity signal fed back by the temperature and humidity sensor 3 through the data processing module 2 and send it to the frequency converter 5. Subsequently, the frequency converter 5 can accurately adjust the power frequency output to the fan motor 6, thereby achieving precise adjustment of the fan motor 6 speed. This setup can quickly and stably respond to speed change requirements, reduce overshoot and adjustment time, and improve energy utilization to a certain extent, achieving energy saving. The initial positioning mechanism 13 set during the installation of the housing 9 can complete the initial installation of the housing 9, and the subsequent locking mechanism 12 can prevent the housing 9 from falling off the initial positioning mechanism 13. The housing 9 is displaced to prevent it from falling off during use. This installation method also facilitates disassembly and maintenance if the housing 9 is damaged. When installing the first mounting plate 16, expansion bolts are used to pass through the mounting groove 17 to install the first mounting plate 16 on the wall. Then, the fixing frame 15 at the rear of the housing 9 is inserted into the limiting block 18 and the baffle 19. The limiting block 18 can then be inserted into the fixing frame 15 to install the housing 9. The baffle 19 can contact one side of the housing 9 to prevent the housing 9 from tilting after installation. After the housing 9 is initially positioned, the connecting rod 21 is inserted into the hidden groove 20. Then, the connecting rod 21 is moved along the hidden groove 20, so that the locking rod 23 can be inserted into the locking groove 24 to further lock the fixing frame 15 and the limiting block 18.
