Description

  The present invention relates to a dehumidifying system for dehumidifying a closed space with high humidity.

  Conventionally, Patent Document 1 discloses that a stored item is dehumidified by dehumidifying the stored item in a closed space blocked from outside air, and the stored item is dried and sterilized with ozone. ing.

  The conventional example shown in this Patent Document 1 is a warm air in which a blower with a heater and an ozone generator are provided in a closed space for putting boots inside, and ozone generated by the ozone generator is blown by a blower with a heater. At the same time, it is sprayed on the boots to dry and sterilize the boots.

  In the above conventional example, ozone is generated for sterilization. However, since ozone adversely affects the human body, it is not preferable for health, and means for removing ozone is required. In addition, ozone is simply attached to the wall of the stored item or enclosed space and sterilized. It cannot penetrate into the interior from the surface of the stored item or wall and sterilize and deodorize it. It was hard to say that the effect was sufficient. In particular, mold propagates from the surface such as the wall surface to the inside, but could not penetrate the inside and exhibit the fungicidal action.

Conventionally, a discharge electrode, water supply means for supplying water to the discharge electrode, and a high voltage application unit for applying a high voltage to the discharge electrode in order to atomize the condensed water supplied to the discharge electrode Patent Document 2 discloses an electrostatic atomizer that is configured to generate electrostatically charged fine particle water by electrostatically neutralizing water supplied to a discharge electrode. The charged fine particle water generated by this electrostatic atomizer is harmless to the human body as compared with ozone, and also has excellent sterilization and deodorizing effects. However, as the water supply means for supplying water to the discharge electrode, for example, when water stored in the water tank is supplied to the tip of the discharge electrode by capillary action, it is necessary to replenish the water tank with water.
JP 2002-172152 A Japanese Patent No. 3260150

  The present invention was invented in view of the above-described conventional problems, and in dehumidifying a closed space with high humidity, at the same time, sterilization in the closed space by charged fine particle water generated by the electrostatic atomizer, Deodorization can be performed effectively, and when generating charged fine particle water in the electrostatic atomizer, the water generated by the dehumidifier can be used effectively and supplied to the discharge electrode. An object of the present invention is to provide a dehumidification system in a closed space that saves the labor of manual work.

  In order to solve the above problems, a dehumidifying system for a closed space according to the present invention includes a dehumidifying means 4 and a blowing means 5 in the middle of an air flow path 3 having one end portion serving as a suction portion 1 and the other end portion serving as a discharge portion 2. The suction part 1 and the discharge part 2 of the dehumidifying device 6 having the above are communicated with the closed space 7, and the air in the closed space 7 is sucked into the air flow path 3 of the dehumidifying device 6 from the suction part 1 by the dehumidifying means 4. The water is dehumidified to form dry air, and the dry air is returned from the discharge unit 2 to the closed space 7 by the blowing means 5, and the water reservoir for storing the water generated by the dehumidifying means 4 in the dehumidifying means 6 is stored. An electrostatic atomizing device 8 is provided in the dehumidifying device 6 to discharge the charged fine particle water to the dry air that has been dehumidified by the dehumidifying means 4, and the electrostatic atomizing device 8 is connected to the discharge electrode 9. A water transport unit for supplying water to the discharge electrode 9 from the water reservoir 13 0 and a high voltage application unit for applying a high voltage to the discharge electrode 9 to electrostatically atomize the water supplied to the discharge electrode, and the water accumulated in the water reservoir 13 is outside the closed space 7. And the evaporation means 14 for making it evaporate out of the dehumidifier 6 is provided, It is characterized by the above-mentioned.

  Although the humid air in the closed space 7 is sucked from the suction portion 1 and dehumidified by the dehumidifying means 4 to be dried air and returned from the discharge portion 2 to the closed space 7, the closed space 7 is dehumidified. In this case, by operating the electrostatic atomizer 8, the water supplied to the discharge electrode 9 is electrostatically atomized to generate charged fine particle water, and the generated charged fine particle water is dehumidified by the dehumidifying means 4 and then dried. Since the air is supplied to the air, the dry air containing the charged fine particle water is returned from the discharge unit 2 to the closed space 7. Therefore, dehumidification of the closed space 7 can be performed, and at the same time, charged fine particle water can be discharged into the closed space 7 to sterilize and deodorize the closed space 7. In particular, the charged fine particle water has a small nanometer size and can penetrate into the inside from the wall surface of the closed space 7 to be sterilized and deodorized. Here, if the charged fine particle water is supplied immediately before dehumidification by the dehumidifying means 4, the charged fine particle water is dehumidified by the dehumidifying means 4, so that the charged fine particle water is mixed into the closed space 7 in the dry air. In the present invention, the charged fine particle water is discharged into the dry air after being dehumidified by the dehumidifying means 4, so that the charged fine particle water is surely mixed into the dry air and discharged into the closed space 7. Can do. Moreover, since the water in the water reservoir 13 is supplied to the discharge electrode 9 by the water transport unit 10, the water generated by dehumidification by the dehumidifying means 4 is effectively used and supplied to the discharge electrode 9 of the electrostatic atomizer 8. And no need to refill the water manually. Moreover, since the total amount of water stored in the water reservoir 13 is too much to be supplied to the discharge electrode 9, it is evaporated by the evaporating means 14 and discharged out of the closed space 7 and out of the dehumidifier 6 so that the water reservoir This saves the labor of manually draining the water accumulated in the tank 13.

  Moreover, it is preferable to control the output of the evaporation means 14 based on the water level of the water reservoir 13.

  With this configuration, it is not necessary to operate the evaporation means 14 unnecessarily, and water supply to the discharge electrode 9 can be ensured.

  Since the present invention is configured as described above, when dehumidifying a closed space with high humidity, at the same time, the charged fine particle water generated by the electrostatic atomizer can sterilize and deodorize the closed space. When generating charged fine particle water in the electroatomizer, water generated by dehumidification by the dehumidifying means can be used effectively and supplied to the discharge electrode, eliminating the need to replenish water manually. In addition, since the total amount of water stored in the water reservoir is too much to supply to the discharge electrode, the water accumulated in the water reservoir can be evaporated by evaporating means and discharged outside the closed space and the dehumidifier. This has the effect of eliminating the trouble of manually disposing of wastewater.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  An air flow path 3 is provided in the dehumidifying device 6, and the air flow path 3 has a suction portion 1 at one end and a discharge portion 2 at the other end. A suction portion 1 at one end of the air flow path 3 and a discharge portion 2 at the other end of the dehumidifying device 6 are connected to a closed space 7 such as a clog box, a storage cabinet, a kitchen, a bathroom, and a floor. The discharge unit 2 is provided with a louver 40.

  The dehumidifying device 6 is provided with a dehumidifying means 4 and a blowing means 5 in the middle of the air flow path 3.

  In the embodiment of FIG. 1, the dehumidifying means 4 is configured by providing a dehumidifying chamber 18 in the middle of the air flow path 3 and providing the dehumidifying chamber 18 with an evaporator 19 and a condenser 20.

  A drainage portion 21 is provided at the bottom of the dehumidifying chamber 18, and the bottom portion has an inclined surface that becomes lower toward the drainage portion 21 side.

  A water reservoir 13 is provided in the lower part of the dehumidifying device 6 so that water flowing down from the drainage part 21 provided at the bottom of the dehumidifying chamber 18 is accumulated.

  A blower storage chamber 22 for storing a fan as the blower 5 is provided downstream of the dehumidification chamber 18 of the air flow path 3. The dehumidification chamber 18 and the blower storage chamber 22 are located downstream of the dehumidification chamber 18. The dry air dehumidified in the dehumidification chamber 18 flows into the blower means storage chamber 22 through the communication port 23 through the communication port 23 provided at the lower end.

  The dehumidifying device 6 operates the air blowing means 5 so that the air in the closed space 7 is sucked in from the suction portion 1 and dehumidified by the dehumidifying means 4 and is returned to the closed space 7 from the discharge portion 2 as dry air. As a result, the enclosed space 7 is dehumidified. For example, taking the case where the closed space 7 is a clog box as an example, when wet or wet footwear is stored in the closed space 7, the dehumidifying device 6 dehumidifies the closed space as described above. 7 is dehumidified, and the stored wet or wet footwear is dried.

  In the embodiment shown in the accompanying drawings, the humid air sucked from the suction part 1 is heat-exchanged by the evaporator 19 and heated, and cooled by the condenser 20 to remove moisture in the air as condensed water. It becomes dry air. Condensed water generated by dehumidification flows from the drainage part 21 to the water reservoir 13 and is stored.

  In the dehumidifying device 6 having the above-described configuration, the dehumidifying device 6 is further provided with an electrostatic atomizing device 8 for discharging charged fine particle water to the dry air after dehumidifying by the dehumidifying means 4.

  The electrostatic atomizer 8 includes a discharge electrode 9, a counter electrode 25 facing the discharge electrode 9, a water transport unit 10 for supplying water from the water reservoir 13 to the discharge electrode 9 by capillary action, a discharge electrode And a high voltage applying unit 15 for applying a high voltage to the discharge electrode 9 in order to atomize the water supplied to the discharge electrode 9.

  The discharge electrode 9 is surrounded by a cylinder 30 made of an insulating material, and a window that communicates the inside and outside of the cylinder 30 is provided on the peripheral wall of the cylinder 30. In addition, the counter electrode 25 has a ring shape and is disposed at the tip opening of the cylindrical body 30, and the discharge is performed so that the center of the ring of the ring-shaped counter electrode 25 is positioned on the extension line of the axial center of the discharge electrode 9. The electrode 9 and the counter electrode 25 are opposed to each other. In the embodiment liquid shown in FIG. 2, a cover 35 made of an insulating material having a discharge port 34 is attached to the tip of the cylindrical body 30.

  The electrostatic atomizer 8 is arranged on the downstream side of the dehumidifying chamber 18 of the air flow path 3 or is arranged outside the air flow path 3 to generate charged fine particle water generated by the electrostatic atomizer 8. Is discharged to the downstream side of the dehumidifying chamber 18 of the air flow path 3.

  The water accumulated in the water reservoir 13 is supplied to the tip of the discharge electrode 9 by the capillary action in the water transport unit 10. When a high voltage is applied between the discharge electrode 9 and the counter electrode 25 in a state where water is supplied to the discharge electrode 9 in this way, the discharge electrode is caused by the high voltage applied between the discharge electrode 9 and the counter electrode 25. The Coulomb force acts between the water supplied to the tip end portion 9 and the counter electrode 25, and the liquid level of the water locally rises in a cone shape (tailor cone). When the tailor cone is formed in this way, the electric charge concentrates on the tip of the tailor cone and the electric field strength in this portion increases, thereby increasing the Coulomb force generated in this portion and further growing the tailor cone. . When the tailor cone grows like this and the charge concentrates on the tip of the tailor cone and the density of the charge becomes high, the water at the tip of the tailor cone has a large energy (repulsive force of the charge that has become dense). In response, the nanoparticle-sized charged fine particle water that is negatively charged by repeating splitting and scattering (Rayleigh splitting) exceeding the surface tension is generated in a large amount. The air is discharged into the dry air flowing downstream from the dehumidifying chamber 18 in the path 3, and is discharged from the discharge unit 2 into the closed space 7 along the dry air flow.

  The charged fine particle water released into the enclosed space 7 is very small and has an active species, and since it has active species, it floats in the enclosed space 7 and flies to every corner of the enclosed space 7 for closure. It effectively decomposes, inactivates, suppresses or disinfects odor components, allergen substances, viruses and fungi in the space 7. In particular, since the charged fine particle water is nanometer-sized water particles, odorous components and allergen substances that permeate into the wall surface of the closed space 7 and the inside of the storage object due to the penetration of water and accumulate inside the wall surface and the storage object. Can be decomposed, inactivated, or suppressed or sterilized.

  By the way, if the charged fine particle water is supplied immediately before dehumidifying by the dehumidifying means 4, the charged fine particle water is dehumidified by the dehumidifying means 4 and therefore disappears, so that the charged fine particle water is mixed into the closed space 7 and released. I can't. However, as described above, since the charged fine particle water is discharged into the dry air after being dehumidified by the dehumidifying means 4, the charged fine particle water can be reliably mixed into the dry air and discharged into the closed space 7. Moreover, since the water in the water reservoir 13 is supplied to the discharge electrode 9 by the water transport unit 10, the water generated by dehumidification by the dehumidifying means 4 is effectively used and supplied to the discharge electrode 9 of the electrostatic atomizer 8. And no need to refill the water manually.

  As described above, a part of the water accumulated in the water reservoir 13 is supplied to the tip of the discharge electrode 9 by the capillary action in the water transport unit 10, but is accumulated in the water reservoir 13. Further, the water is further evaporated by the evaporation means 14 and discharged to the outside. In the embodiment shown in the accompanying drawings, the dehumidifying device 6 is provided with a heater 14a and a fan 14b to constitute the evaporating means 14, and the heater 14a evaporates water accumulated in the water reservoir 13, and the dehumidifying device 6 by the fan 14b. It discharges to the outside (outside the closed space 7 and the dehumidifier 6) from a discharge port 32 provided in the case 31. Thereby, the labor which drains the water collected in the water reservoir 13 manually can be saved.

  As shown in FIG. 1, the water reservoir 13 is provided with water level detection sensors A, B, C, and D. Here, the water level detection sensor A is for detecting the lowest water level, and the water level detection sensor D is for detecting the highest water level.

  Then, the water level in the water reservoir 13 is detected by the water level detection sensors A, B, C, and D, and the dehumidifying means 4, the electrostatic atomizer 8 and the evaporation means 14 of FIG. Control is performed as shown in the flow diagram. In the flow chart of FIG. 3, high pressure: electrostatic atomizer 8, evaporation acceleration: heater 14a, fan 14b, dehumidification: evaporator 19, condenser 20, and blowing means 5 are shown.

  That is, as shown in the flowchart of FIG. 3, when the water level is detected by the water level detection sensor and the water level is not detected by the water level detection sensor A (that is, when the water level is lower than the water level A detected by the water level detection sensor A) B) Control to turn off the high pressure, turn off acceleration, and turn on dehumidification.

  When the water level detection sensor A detects the water level and the water level detection sensor B does not detect the water level (that is, when the water level is above A and below B), the high pressure is on, the evaporation acceleration is off, and the dehumidification is on. Control is performed as follows.

  Also, when the water level detection sensor B detects the water level and the water level detection sensor C does not detect the water level (that is, when the water level is above B and below C), high pressure on, evaporation acceleration on, dehumidification on Control is performed as follows.

  Also, when the water level detection sensor C detects the water level and the water level detection sensor D does not detect the water level (that is, when the water level is above C and below D), high pressure on, evaporation acceleration on, dehumidification off Control is performed as follows.

  When the water level is detected by the water level detection sensor D (that is, when the water level is higher than D), control is performed such that high pressure is turned off, evaporation acceleration is turned on, and dehumidification is turned off.

  By automatically controlling the dehumidifying means 4, the electrostatic atomizer 8, and the evaporating means 14 according to the water level of the water reservoir 13 that stores the water generated by dehumidifying by the dehumidifying means 4 in this way, The overflow of water from the reservoir 13 is prevented, and when there is little or no water in the reservoir 13, the electrostatic atomizer 8 and the evaporation means 14 are unnecessarily operated and wasteful. It is possible to prevent the use of various energies and improve safety, and to operate effectively according to the water level.

  In the embodiment shown in the accompanying drawings, an example of the electrostatic atomizer 8 that generates charged fine particle water by applying a high voltage between the discharge electrode and the counter electrode is shown. There may be.
