Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1
[0022] Refer to Figure 1-8 , which is the first embodiment of the present utility model. This embodiment provides a new type of solar intelligent dehumidification cabinet, including a dehumidification cabinet body 1, a current detection unit 2, a storage battery 3, a controller 4, and a solar charge and discharge control circuit 5. The output end of the current detection unit 2 is connected to the input end of the controller 4, the switch command output end of the controller 4 is connected to the switch command input end of the dehumidification cabinet body 1, and the solar charge and discharge control circuit 5 is electrically connected to the storage battery 3.
[0023] Embodiment 2
[0024] Refer to Figure 1-8, which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. Specifically, the dehumidification cabinet body 1 includes a white JSDI hydrophilic layer 101, a heating device 102, a drainage pipeline 103, a water storage tank 104, a temperature sensor 105, a humidity sensor 106, a solar device 107, a black JSDI 108, and a blower 109. The inner surface of the dehumidification cabinet body 1 is provided with a white JSDI hydrophilic layer 101. A drainage pipeline 103 is arranged inside the white JSDI hydrophilic layer 101. The drainage pipeline 103 is connected to the water storage tank 104. A black JSDI 108 and a sealed glass are arranged at the rear side of the dehumidification cabinet body 1. A heating device 102 is arranged in the white JSDI hydrophilic layer 101. An exhaust hole is arranged at the top of the dehumidification cabinet body 1. A blower 109, a temperature sensor 105, and a humidity sensor 106 are respectively arranged on the side wall of the dehumidification cabinet body 1. The heating device 102, the temperature sensor 105, and the humidity sensor 106 are all electrically connected to the current detection unit 2. A solar device 107 is fixedly installed at the top of the dehumidification cabinet body 1.
[0025] Referring to Figure 8 As shown, both the white JSDI hydrophilic layer 101 and the black JSDI 108 adopt the Janus structure. Their basic principles are the same, only the composition of the surface film is different. For the Janus structure, its composition is a hydrophilic porous film composed of a surface film and a copper mesh. When it works, the water vapor inside the copper mesh moves towards the hydrophilic porous layer through the water channels. However, due to the blocking effect of the copper mesh, the water vapor cannot move, so water droplets accumulate on the copper mesh. As the process continues, the water droplets become larger and larger, which hinders the water transportation from the hydrophilic porous film into the copper mesh. At the same time, the water droplets on the inner side of the copper mesh have a larger mass and are transported outward under the action of the Laplace pressure. When passing through the surface film on the hydrophilic porous film, the surface film provides surface energy to evaporate them, thus realizing the transportation of water vapor against the gravity direction. For the white Janus structure and the black Janus structure, their basic principles are the same, only the composition of the surface film is different, which leads to different dehumidification efficiencies. It is found through experiments that the efficiency difference between the black and white JSDIs reaches 1.46 times, and the conversion efficiency of the black JSDI is about 90.8%.
[0026] The dehumidification area mainly utilizes the Janus membrane structure, supplemented by a fan 109 and a heating device 102 to dehumidify the dehumidification cabinet body 1. The hydrophilic side of the Janus membrane can absorb the moisture in the surrounding environment, similar to the function of an adsorbent. When the moisture contacts this side, due to the influence of surface tension and capillary action, the moisture will be adsorbed on the membrane surface and diffused into the membrane interior. The hydrophobic side will repel the moisture and promote its outward diffusion. The surface of this side can effectively prevent the penetration of water and push it out of the membrane, thus achieving the exclusion of moisture. The key to Janus membrane dehumidification lies in the rapid removal of moisture. Once the moisture is absorbed into the moisture-absorbing side inside the membrane, it will diffuse outward through the channels or pores inside the membrane and then be excluded by the hydrophobic surface on the moisture-excluding side. This process can effectively remove the moisture from inside the membrane quickly, achieving a fast and efficient dehumidification effect.
[0027] Furthermore, the heating device 102 is made of stainless steel pipe; the solar panel mainly consists of an aluminum frame, photovoltaic glass, encapsulation gel EVA, solar cells, back wires, and junction boxes.
[0028] The solar power generation system is composed of a photovoltaic panel, a solar controller, an inverter, and a storage battery. The first three are connected in series in sequence, the output end of the last inverter is connected to the controller and the heating device 102, and the storage battery is connected in parallel to the solar controller. When the current generated by the light intensity exceeds the set value current in the heating device, the storage battery is charged, and the excess current flows into the storage battery to control the current within the specified value. When the current generated by the light intensity is less than the set value current in the heating device 102, the storage battery 3 supplies power to the heating device 102 to control the current within the specified value. This device adjusts the current in the heating circuit through negative feedback to keep its current intensity always at the specified value, so that the device is always in the heating state.
[0029] Furthermore, the temperature sensor 105 uses a thermocouple temperature sensor, and the humidity sensor 106 uses a linear frequency output integrated humidity sensor.
[0030] Introduction to the temperature control device ZY9080B: This product can simultaneously achieve two functions of temperature measurement and relative humidity measurement. It uses a chip digital humidity probe, which can truly achieve high precision, no humidity drift, and more reliable performance. This product mainly can achieve two-way control outputs of temperature control + humidity control, real-time display of temperature and humidity, a wide temperature control range, has a temperature correction function, and has a power-off memory function. This temperature control device has 8 wiring ports, among which 2, 4, 5, and 6 are connected to the power supply, 1 and 6 are connected to the heating equipment, 3 and 6 are connected to the dehumidification equipment, and its temperature and humidity control functions are realized through correct wiring.
[0031] Specifically, the current detection unit 2 includes a current sensing element 201, a conversion circuit 202, and a signal amplification circuit 203. The output end of the current sensing element 201 is connected to the input end of the conversion circuit 202, the output end of the conversion circuit 202 is connected to the input end of the signal amplification circuit 203, and the output end of the signal amplification circuit 203 is connected to the current information input end of the controller 4.
[0032] Specifically, the controller 4 includes a resistor R1, a resistor R2, a resistor R3, a resistor R4, a fan G, a humidity and temperature control device Z, a three-state output NAND gate, a NOT gate, and a transformer B. The solar energy device 107 is connected in series with the fan G and the resistor R1. The transformer B is connected in parallel across the two ends of the fan G. The transformer B is connected in series with the resistor R2 and the temperature control device of the humidity and temperature control device Z. The temperature control device is connected to the input end of the three-state output NAND gate. The transformer B is connected in series with the resistor R3 and the humidity control device of the humidity and temperature control device Z. The humidity control device is connected to the input end of the three-state output NAND gate. The transformer B is connected in series with the power supply end of the humidity and temperature control device Z. The sensor end of the humidity and temperature control device Z is connected in series with the resistor R4 to form a loop. The output end of the three-state output NAND gate, the NOT gate, and the heating tube are connected in series to one end of the transformer B.
[0033] The solar energy system converts solar energy into an electrical signal and inputs it into the circuit. The input electrical signal flows through the fan 109, causing it to start working normally. Then it flows through the transformer, and after voltage division, it flows through the secondary circuit. When it flows through the temperature and humidity control device (ZY9080B), this chip will collect the data of the temperature and relative humidity inside the device and compare it with the set value. If both the temperature and relative humidity inside the device are higher than the set value, the switch inside the temperature and humidity control device (ZY9080B) closes, the TTL gate outputs a signal of 0, the NAND gate outputs a signal of 1, and the heating tube starts to heat. If either the temperature or the relative humidity inside the device is lower than the set value, the switch inside the temperature and humidity control device (ZY9080B) opens, the TTL gate outputs a signal of 1, the NAND gate outputs a signal of 0, and the heating tube stops heating.
[0034] Embodiment 3
[0035] Refer to Figure 1-8, which is the third embodiment of the present utility model. This embodiment is based on the above two embodiments. When in use, the solar energy system converts solar energy into electrical signals and inputs them into the circuit. The input electrical signals flow through the fan 109, causing it to start working normally. Then, they flow through the transformer, and after voltage division, they flow through the secondary circuit. When flowing through the temperature control device (ZY9080B), this chip will collect data on the temperature and relative humidity inside the device and compare it with the set values. If both the temperature and relative humidity inside the device are higher than the set values, the switch inside the temperature control device (ZY9080B) closes, the TTL gate outputs a signal of 0, the NAND gate outputs a signal of 1, and the heating tube starts heating. If either the temperature or relative humidity inside the device is lower than the set value, the switch inside the temperature control device (ZY9080B) disconnects, the TTL gate outputs a signal of 1, the NAND gate outputs a signal of 0, and the heating tube stops heating. When the heating device 102 operates, the steel pipes inside the cabinet body of the dehumidification cabinet body 1 start to heat up, and water starts to evaporate and is absorbed by the white Janus structure of the white JSDI hydrophilic layer 101, causing the moisture to enter the water tank and then enter the water storage tank 104 by gravity. At the same time, the fans 109 on both sides of the cabinet start, discharging the dry air outside the cabinet to accelerate the dehumidification process. For some water vapor, it is absorbed by the black Janus structure of the black JSDI 108 and undergoes a photothermal effect under the sun's radiation and is then sent into the interlayer, where it condenses into water and then flows into the main water tank. As the water vapor is continuously discharged, the humidity inside the dehumidification cabinet body 1 continuously decreases. When the humidity inside the cabinet drops below the set value, the switch of the temperature sensor 105 inside the temperature control device (ZY9080B) disconnects, the indicator light goes out, the circuit disconnects, and the fan 109 and the heating device 102 stop working, and the dehumidification is completed. When the heating device 102 is not working, on the one hand, the dehumidification cabinet body 1 relies on the white Janus structure of the white JSDI hydrophilic layer 101 to absorb water vapor, and the water directly enters the water storage tank 104 through the internal drainage pipeline 103. On the other hand, it relies on the black Janus structure of the black JSDI 108 to absorb water vapor, and the water is guided to the water tank through the photothermal effect, thus achieving the dehumidification effect.
