  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the dehumidifying device of this embodiment includes a main body case 4 having a first air inlet 1, a second air inlet 2, and an air outlet 3, and a heat pump provided in the main body case 4. And 5. The heat pump 5 is formed by a compressor 6, a radiator 7, an expansion means 8, and a heat absorber 9 that are sequentially provided downstream of the compressor 6. Here, air is sucked into the main body case 4 from the first air inlet 1 and the second air inlet 2, and the sucked air is divided into three air passages and flows again through the main body case 4. They gather together and are blown into the room from the exhaust port 3.

  First, the first air passage 10 communicates air sucked into the main body case 4 from the first air inlet 1 to the air outlet 3 through the radiator 7, the heat absorber 9, and the first air blowing means 11 in this order. It is a ventilation path. Next, the second air passage 12 is an air passage that communicates the air sucked into the main body case 4 from the second air inlet 2 to the exhaust port 3 via the heat absorber 9 and the first air blowing means 11. is there. Finally, the third air passage 13 is an air passage that communicates the air sucked into the main body case from the first air inlet 1 to the air outlet 3 via the radiator 7 and the second air blowing means 14. . Here, a moisture releasing portion 16 of the dehumidifying rotor 15 is provided between the radiator 7 and the heat absorber 9 of the first air passage 10, and the moisture absorbing portion 17 of the dehumidifying rotor 15 is connected to the first air passage 10 and the second air outlet 10. This is provided between the heat absorber 9 and the exhaust port 3 of the air passage 12.

  That is, the refrigerant pressurized by the compressor 6 is sent to the radiator 7, where the air sucked into the main body case 4 from the first air inlet 1 and the second air inlet 2 is heated. Next, the refrigerant that has passed through the radiator 7 reaches the expansion means 8 and then returns to the compressor 6 through the heat absorber 9.

  In the first air passage 10, the air sucked into the main body case 4 from the first air inlet 1 is heated by the radiator 7 by the first air blowing means 11, and the air is then heated by the heater 18. Then, it passes through the moisture release portion 16 of the dehumidifying rotor 15 and flows to the heat absorber 9 in a state where the moisture from the moisture release portion 16 is taken away. In the second air passage 12, the air sucked into the main body case 4 from the second air inlet 2 by the first air blowing means 11 flows to the heat absorber 9. The air is first condensed in the heat absorber 9, and the condensed water is stored in the water storage tank 19.

  Now, the air that has passed through the heat absorber 9 is cooled to a low temperature by the heat absorber 9, but the humidity is extremely high although the temperature is low. This low-temperature air containing high humidity then passes through the hygroscopic part 17 of the dehumidifying rotor 15, and this hygroscopic part 17 is driven to rotate by the drive means 20 so that the upper part of FIG. Since the moisture is already released at the moisture release portion 16 and the humidity is low, moisture can be absorbed from the air having a very high humidity despite the low temperature. In this way, the air further dehumidified by the moisture absorbing portion 17 of the dehumidifying rotor 15 is blown to the exhaust port 3 by the first blowing means 11. On the other hand, in the third air passage 13, the air sucked into the main body case 4 from the first air inlet 1 is heated by the radiator 7 by the second air blower 14, and the air is blown to the air outlet 3. To do.

  That is, the air dehumidified through the first air passage 10 and the second air passage 12 and the air heated through the third air passage 13 gather at the exhaust port 3 and are blown into the room from the exhaust port 3. Is.

  A feature of the present embodiment is that a communication passage 21 that connects the second air passage 12 and the second air blowing means 14 is provided, and an electrostatic atomizing means 22 is provided in the communication passage 21, and the air blowing means of the communication passage 21 is provided. The negative pressure generating means 23 is provided on the side.

  That is, in the present embodiment, a communication passage 21 that communicates the upstream air passage of the heat absorber 9 of the second air passage 12 and the second air blowing means 14 is provided, and the electrostatic atomizing means 22 is provided in the communication passage 21. Since the negative pressure generating means 23 is provided on the air blowing means side of the communication passage 21, the indoor air sucked into the main body case 4 from the second intake port 2 is communicated by the negative pressure generating means 23 to the communication passage 21. To the electrostatic atomizing means 22, and the electrostatic atomizing means 22 generates charged particulate water 24 from indoor air. The charged fine particle water 24 is blown to the laundry from the exhaust port 3 together with the dehumidified dry air. Here, the charged fine particle water 24 reacts with the odor component of the laundry, and the hydroxyl radicals in the charged fine particle water 24 cause an odor. The component can be decomposed and removed. In other words, a hydroxyl radical is a radical corresponding to a hydroxy group (hydroxyl group), and this radical usually has only one electron that should be rotating in orbit in pairs, which is very electrically electrically. It is anxious and has strong oxidizing power because it tries to take away missing electrons from surrounding atoms and molecules. The odor component can be decomposed and removed by this oxidizing power.

  Based on these results, it is possible to suppress the generation of odors from the dry portion of the laundry.

  From these results, even when it takes time to dry the laundry, it is possible to suppress the generation of odor from the laundry and further increase the drying ability.

  As shown in FIGS. 2 and 3, the electrostatic atomizing means 22 includes a discharge electrode 25, a counter electrode 26 disposed opposite to the discharge electrode 25, and between the discharge electrode 25 and the counter electrode 26. A high voltage application unit 27 that applies a high voltage to the discharge electrode 25, a cooling unit 28 that cools the discharge electrode 25, and a radiation fin unit 29 that radiates heat from the cooling unit 28. It is provided so as to protrude into the blowing means 11. Specifically, the discharge electrode 25 is formed of a substantially rectangular flat plate portion 30 and a cylindrical column portion 31 extending in the vertical direction from the center of the flat plate portion 30. A substantially cylindrical counter electrode 26 having a predetermined distance from the tip of the columnar part is provided on the tip side of the columnar part 31, and a flat plate in contact with the flat plate part 30 is provided on the base side of the columnar part 31 of the discharge electrode 25. A Peltier element 32 which is a cooling unit 28 having a shape is provided. On the other surface side of the Peltier element 32, a heat radiating fin portion 29 is provided in contact. The heat radiating fin portion 29 is formed of a heat radiating flat plate portion 33 in contact with the Peltier element 32 and a plurality of fin portions 34 extending from the heat radiating flat plate portion 33 in the vertical direction. The plurality of fin portions 34 protrude into the first air blowing means 11.

  Here, the operation of the electrostatic atomizer 22 will be described. First, when the Peltier element 32 is energized, heat moves from the contact surface side of the discharge electrode 25 to the flat plate portion 30 to the contact surface side of the heat dissipation fin portion 29 to the heat dissipation flat plate portion 33. That is, heat is transferred from the flat plate portion 30 of the discharge electrode 25 to the radiation fin portion 29, and the discharge electrode 25 is cooled. As a result, the tip of the cylindrical portion 31 of the discharge electrode 25 is cooled, so that condensation occurs at the tip 35 and water is generated on the surface of the tip 35. Next, when a high voltage is applied between the discharge electrode 25 and the counter electrode 26 by the high voltage application unit 27, the tip portion 35 of the discharge electrode 25 becomes a negative electrode, and charges are concentrated, so that water on the surface of the tip portion 35 is concentrated. And a counter electrode 26, a Coulomb force acts to form a weight-like portion in which water rises like a weight. When the electric charge is further concentrated on the tip of the spindle-shaped portion, the charged fine particle water 24 charged negatively is generated by repeatedly splitting and scattering beyond the surface tension of water. Here, the heat transferred from the discharge electrode 25 to the radiating fin portion 29 is cooled by the radiating fin portion 29, whereby the movement of heat from the discharge electrode 25 to the radiating fin portion 29 is repeated.

  That is, the radiating fin portion 29 protrudes into the first air blowing unit 11, and condensation is performed by the heat absorber 9 and low temperature air flows into the first air blowing unit 11. The fin portion 29 can be easily cooled, and condensation can be easily generated at the tip portion 35 of the cylindrical portion 31 of the discharge electrode 25.

  As shown in FIGS. 3 and 4, the first air blowing means 11 and the second air blowing means 14 include a double suction casing 36, an electric motor 37 provided in the casing 36, and an electric motor 37. The casing 36 is formed of a first casing 39 and a second casing 40, and the blade 38 is formed of a first blade portion 42 extending from one surface of the main plate 41, and the main plate 41. The second blade portion 43 extends from the other surface of the first casing 39, and includes a partition plate 44 between the first casing 39 and the second casing 40. The second air blowing means 14 is formed from the electric motor 37, the second casing 40, and the second blade portion 43 of the blade 38, and the second blade means 43 is formed from the first blade portion 42 of the blade 38. Second casein The discharge opening neighborhood of 40 is provided with a communication passage 21. Specifically, the first air blowing means 11 and the second air blowing means 14 are formed by both suction type air blowing means 46, one suction side being the first air blowing means 11, and the other suction side being the second air suction means. The air blowing means 14. That is, an electric motor 37 is provided in a double-suction type casing 36, and a double-suction type blade 38 rotated by the electric motor 37 is provided. Both suction-type casings 36 are formed from a first casing 39 that is one suction side and a second casing 40 that is the other suction side, and the blade 38 is one of the ones extending from one surface of the main plate 41. The first blade portion 42 on the suction side and the second blade portion 43 on the other suction side extending from the other surface of the main plate 41 are formed. A partition plate 44 is provided between the first casing 39 and the second casing 40 and on the same plane as the main plate 41 of the blade 38. That is, the first air blowing means 11 and the second air blowing means 14 are partitioned by the partition plate 44, and the first air blowing means 11 is composed of the electric motor 37, the first casing 39, and the first blade portion 42. The second air blowing means 14 is formed from an electric motor 37, a second casing 40, and a second blade portion 43. Here, the communication passage 21 is provided in the vicinity of the discharge port 45 of the second casing 40 which is the second air blowing means 14.

  That is, the indoor air sucked into the main body case 4 from the second air inlet 2 by the first air blowing means 11 is supplied from the upstream air passage of the heat absorber 9 of the second air passage 12 to the negative pressure generating means 23. Is sent to the electrostatic atomization means 22 of the communication passage 21, and the electrostatic atomization means 22 generates charged particulate water 24 from the indoor air. Here, since the communication path 21 is provided in the vicinity of the discharge port 45 of the second casing 40, the charged fine particle water 24 generated by the electrostatic atomizing means 22 is the second blade that is the second blowing means 14. The air is blown into the room from the exhaust port 3 by the blowing of the second blowing means 14 without hitting the portion 43. As a result, it is possible to prevent the charged fine particle water 24 generated by the electrostatic atomizing means 22 from being reduced by hitting the second blade portion 43 which is the second blowing means 14.

  As shown in FIG. 4, the negative pressure generating means 23 is a protruding portion 49 that protrudes from the side peripheral surface 47 of the second casing 40 toward the tongue portion 48. Specifically, the protruding portion 49 is a substantially rectangular flat plate that is inclined and protrudes from the side peripheral surface 47 of the second casing 40 toward the tongue portion 48. That is, a part of the side peripheral surface 47 of the second casing 40 is inclined from the side peripheral surface 47 of the second casing 40 to the tongue side.

  That is, at the beginning of winding of the casing, the air blown into the second casing 40 from the second blade portion 43 that is the second blowing means 14 is along the inner circumferential surface of the second casing 40. The air is blown from the vicinity of a certain tongue 48 toward the discharge port 45 which is the end of winding of the casing. In the middle of this, a part of the air flows from the inner peripheral surface of the second casing 40 along the protruding portion 49 that is the negative pressure generating means 23 and flows in the direction of the discharge port 45. Here, the air flowing along the projecting portion 49 flows from the leeward end of the projecting portion 49 toward the discharge port 45 or the inner surface of the second casing 40. At this time, a vortex is generated. Since the vortex part has a negative pressure, the air in the communication passage 21 flows into the second casing 40. That is, indoor air flows from the upstream air passage of the heat absorber 9 of the second air passage 12 to the electrostatic atomizing means 22 of the communication passage 21, and the charged particulate water 24 generated by the electrostatic atomizing means 22 is generated. The second blower 14 blows air from the exhaust port 3 into the room. As a result, it is possible to prevent the charged fine particle water 24 generated by the electrostatic atomizing means 22 from being reduced by hitting the negative pressure generating means 23.

  As shown in FIG. 3, the negative pressure generating means 23 is provided near the partition plate 44 of the second casing 40. Specifically, the protrusion 49 is a substantially rectangular flat plate extending from the partition plate 44, and is inclined and protrudes from the peripheral surface on the second casing 40 side toward the tongue 48.

  That is, the protruding portion 49 that is the negative pressure generating means 23 is located closer to the partition plate 44 of the second casing 40, that is, away from the suction port 50 of the second casing. The air blown from the vicinity of the tongue portion 48, which is the start of winding of the casing, toward the discharge port 45, which is the end of winding of the casing, along the side peripheral surface, is compared to the suction port 50 of the second casing. Since the air volume near the partition plate 44 of the second casing 40 is larger, the air volume flowing along the protruding portion 49 that is the negative pressure generating means 23 also increases, and the generation of vortices increases. Accordingly, the amount of air flowing from the upstream air passage of the heat sink 9 of the second air passage 12 to the electrostatic atomizing means 22 of the communication passage 21 is increased, and as a result, charged fine particle water generated by the electrostatic atomizing means 22 is increased. 24 can be increased.

  Further, as shown in FIG. 4, the negative pressure generating means 23 is a part of the communication path 21. Specifically, the communication passage 21 is a substantially rectangular tube portion having a substantially rectangular tube shape that protrudes from the peripheral surface of the second casing 40 toward the tongue portion 48, and is perpendicular to the partition plate 44 of the second casing 40. One surface extending in the direction is the protrusion 49 of the negative pressure generating means 23.

  That is, the protruding portion 49 that is the negative pressure generating means 23 also serves as a part of the substantially rectangular tube-shaped substantially square tube portion that is the communication path 21, so that the portion protruding into the second casing 40 can be made compact. Therefore, wind noise generated when the air in the second casing 40 hits the negative pressure generating means 23 and the communication passage 21 can be suppressed.

  As shown in FIG. 3, the heat radiating fin portion 29 of the electrostatic atomizer 22 includes a heat radiating plate portion 33 in contact with the cooling portion 28 and a plurality of fin portions 34 extending from the heat radiating plate portion 33 in the vertical direction. It is formed from.

It is formed. The fin portions 34 having a substantially square plate shape are adjacent to each other with a predetermined distance between the adjacent fin portions 34.

  That is, since the heat radiating fin portion 29 of the electrostatic atomizing means 22 is formed by a plurality of fin portions 34 extending in the vertical direction from the heat radiating plate portion 33 in contact with the cooling portion, the surface area of the heat radiating fin portion 29 is large. Thus, the contact area with the air in the first casing 39 can be increased, and as a result, the amount of heat released from the heat radiating fin portion 29 can be increased.

  Further, as shown in FIG. 3, the heat dissipating fin portion 29 of the electrostatic atomizing means 22 is projected from the partition plate 44 into the first air blowing means 11. Specifically, the radiating fin portion 29 includes a substantially rectangular flat plate-shaped radiating flat plate portion 33 in contact with the cooling portion 28 and a plurality of substantially rectangular flat plate-shaped fin portions 34 extending from the radiating flat plate portion 33 in the vertical direction. It is formed. The substantially rectangular flat plate-shaped fin portion 34 is projected from the partition plate 44 into the first air blowing means 11.

  That is, since the fin part 34 which is the radiation fin part 29 protrudes from the partition plate 44 of the first casing 39, that is, is located away from the suction port 51 of the first casing, the first casing The air blown in the direction of the discharge port 52 that is the end of winding of the casing from the vicinity of the tongue 53 that is the start of winding of the casing, along the inner peripheral surface, is closer to the suction port 51 of the first casing, Since the air volume near the partition plate 44 of the first casing 39 is larger, the air volume flowing through the radiating fin portion 29 becomes larger, and as a result, the radiating amount from the radiating fin portion 29 can be increased.

  Further, as shown in FIG. 5, the fin portion 34 of the radiating fin portion 29 of the electrostatic atomizing means 22 has a substantially rectangular flat plate shape and is provided substantially parallel to the wind direction in the first air blowing means 11. is there. Specifically, the radiating fin portion 29 includes a substantially rectangular flat plate-shaped radiating flat plate portion 33 in contact with the cooling portion 28 and a plurality of substantially rectangular flat plate-shaped fin portions 34 extending from the radiating flat plate portion 33 in the vertical direction. It is formed. The fin portions 34 having a substantially square flat plate shape are located substantially parallel to each other with a predetermined distance between the adjacent fin portions 34, and are substantially parallel to the wind direction in the first air blowing means 11, that is, in the vicinity. The first casing 39 is provided substantially in parallel with the inner peripheral surface of the inner surface.

  That is, at the beginning of winding of the casing, the air blown into the first casing 39 from the first blade portion 42 which is the first blowing means 11 is along the inner peripheral surface of the first casing 39. Air is blown from the vicinity of a certain tongue 53 toward the discharge port 52, which is the end of winding of the casing. In the middle of this, a part of the air flows in parallel along the plurality of fin portions 34 of the substantially rectangular flat plate shape of the radiating fin portion 29 along the inner peripheral surface of the first casing 39.
