  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment)
In FIG. 1, reference numeral 1 denotes a vertically long box-shaped main body case having an intake port 2 and an exhaust port 3. The main body case 1 has a substantially square-shaped intake port 2 on the back side, a substantially horizontally long exhaust port 3 on the upper front side, and a receiving tray 4 that can be raised and lowered below the front side. ing.

  Further, a disc-shaped dehumidifying rotor 7 having a moisture absorbing portion 5 and a moisture releasing portion 6 is rotatably disposed in the main body case 1 so as to face the air inlet 2, and the rotational drive thereof is performed by a motor 8. Is to be done by. The rotational axis direction of the dehumidifying rotor 7 is the front-rear direction in the main body case 1.

  Further, as indicated by an arrow A in FIG. 1, indoor air sucked from the air inlet 2 of the main body case 1 passes through the moisture absorbing portion 5 of the dehumidifying rotor 7 and then passes through the exhaust port 3 to the front in the main body case 1. A first air blowing means 9 for exhausting air from the main body case 1 is provided.

  The first air blowing means 9 includes a rear side intake section 10 shown in FIG. 2, a casing 12 having an upper exhaust section 11, blades 13 provided in the casing 12, and an electric motor that drives the blades 13. 18, the indoor air after passing through the moisture absorption part 5 of the dehumidifying rotor 7 flows into the casing 12 from the intake part 10 and is pressurized by the blades 13, and as shown in FIG. 3 is exhausted to the outside of the main body case 1.

  Further, as shown in FIG. 1, a moisture absorption path 14 is provided in the main body case 1, and the moisture absorption path 14 is provided on the moisture release portion 6 of the dehumidification rotor 7 and on the windward side of the moisture release portion 6. The heater 15, the heat exchanger 16 provided on the leeward side of the moisture release section 6, and the second air blowing means 17 for circulating the air in the moisture absorption path 14 are included. The moisture absorption path 14 is independent as a ventilation path in the main body case 1.

  The heater 15 is opposed to the moisture release portion 6 of the dehumidification rotor 7 and is located on the front side of the body case 1 of the moisture release portion 6 of the dehumidification rotor 7. The heat exchanger 16 is located next to the dehumidifying rotor 7 on one side in the left-right direction of the main body case 1, and the moisture releasing portion 6 of the dehumidifying rotor 7 is located on the other side in the left-right direction of the main body case 1. is there. That is, a part of the moisture absorbing portion 5 of the dehumidifying rotor 7 is located between the heat exchanger 16 and the moisture releasing portion 6 of the dehumidifying rotor 7.

  Further, as shown by an arrow B in FIG. 1, the indoor air sucked into the main body case 1 from the air inlet 2 by the first air blowing means 9 passes through the heat exchanger 16 of the moisture absorption path 14 in the main body case 1. Thereafter, a first air passage for exhausting air from the exhaust port 3 to the outside of the main body case 1 is formed via the first air blowing means 9.

  However, the indoor air indicated by the arrow B is only exchanged with the air in the moisture absorption path 14 passing through the heat exchanger 16 through a heat conduction surface constituting the heat exchanger 16. It is not mixed in 16 parts.

  Here, the operation of the moisture absorption path 14 will be described. The air in the moisture absorption path 14 heated by the heater 15 is dampened in the moisture release section 6 (this release section 6 when the moisture absorption section 5 of the dehumidification rotor 7 rotates). The high-temperature and excessively humid air is sent to the heat exchanger 16 on the leeward side.

  As described above, since the indoor air is blown to the heat exchanger 16 by the first blowing means 9 as shown by the arrow B, the high-temperature and excessively humid air is cooled, thereby condensing. This is stored in the tray 4.

  The moisture absorbing portion 5 of the dehumidifying rotor 7 adsorbs moisture every time indoor air passes as indicated by an arrow A, and this becomes the moisture releasing portion 6 described above by the rotation of the dehumidifying rotor 7 and becomes the moisture absorbing path 14. Moisture is released into the interior, and the indoor air is dehumidified by such circulation.

  Now, the feature in this embodiment is that the electrostatic atomizing means 19 is located between the dehumidification rotor 7 and the intake port 2 in the blowing path of the first blowing means 9.

  Specifically, as shown in FIGS. 3, 4, and 5, the electrostatic atomizing means 19 includes a case portion 21 having a first communication port 22 and a second communication port 23, and the inside of the case portion 21. It forms from the electrostatic atomization generation | occurrence | production part 20 provided in this. The electrostatic atomization generator 20 includes a discharge electrode 24, a counter electrode 25 disposed opposite to the discharge electrode 24, and a high voltage application that applies a high voltage between the counter electrode 25 and the discharge electrode 24. It is formed of a part 26, a cooling part 27 that cools the discharge electrode 24, and a radiation fin 28 that radiates heat from the cooling part 27.

  The first air blowing means 9 is formed of a scroll-shaped casing 12, blades 13 provided in the casing 12, and an electric motor 18 that rotates the blades 13. The casing 12 is provided with a negative pressure generating hole 29, and a communication air passage 30 is provided to communicate the negative pressure generating hole and the electrostatic atomizing means.

  The first communication port communicates with the communication air passage 30, and the electrostatic atomizing means is located between the dehumidification rotor 7 and the intake port 2 in the air blowing path of the first air blowing means 9.

  That is, in the present invention, the electrostatic atomizing means 19 is located between the dehumidification rotor 7 and the air inlet 2 in the air blowing path of the first air blowing means 9, and the first air blowing means 9 The air is not heated by the moisture absorbing portion 5 of the dehumidifying rotor 7 or the heat exchanger 16, and flows from the air inlet 2 to the heat radiation fin 28. In other words, the indoor air that has been advanced without being heated by the moisture absorbing portion 5 of the dehumidifying rotor 7 or the heat exchanger 16 is cooled at the discharge electrode 24 portion, so that dew condensation generates charged particulate water. .

  For this reason, the generation amount of the charged fine particle water by the electrostatic atomizing means 19 can be further improved. This charged fine particle water is then exhausted from the exhaust port 3 to the outside of the main body case 1 together with dry air, and the hydroxyl radicals in the charged fine particle water react with the odor that is characteristic of the dryness of laundry, and oxidize it. Odor generation can be suppressed.

  Further, the heat radiating fins 28 protrude from the case portion 21 toward the intake port 2 side. Specifically, the electrostatic atomizing means 19 includes a discharge electrode 24, a counter electrode 25 disposed opposite to the discharge electrode 24, and a high voltage (this voltage between the counter electrode 25 and the discharge electrode 24). In the embodiment, a high voltage applying unit 26 that applies −5 KV), a Peltier element 31 disposed as a cooling unit 27 that cools the discharge electrode 24, and a radiation fin 28 that radiates the heat of the Peltier element 31 are provided. . The Peltier element 31 applies a voltage of about 0.75 V to 2.8 V. In this embodiment, the discharge electrode 24 side is set to a low temperature and the radiation fin 28 side is set to a high temperature.

  That is, the radiation fin 28 that radiates the heat of the Peltier element 31 is opposed to the intake port 2. Thus, the first air blowing means 9 causes the indoor air to flow directly from the intake port 2 to the radiating fin 28 without being heated by the moisture absorbing portion 5 of the dehumidifying rotor 7 or the heat exchanger 16.

  In addition, the electrostatic atomizing means 19 is configured to be separated from the heater 15 in the rotational direction of the dehumidification rotor 7 by a half or more circumference to the downstream side in the rotational direction of the dehumidification rotor 7. Specifically, as shown in FIG. 4, the dehumidifying rotor 7 rotates in the same direction as the hands of the watch as seen from the back side of the main body case 1. A regeneration chamber 32 is located on the upper right side of the dehumidifying rotor 7, which is the upper right side of the main body case 1 when viewed from the back side of the main body case 1. The regeneration chamber 32 faces the moisture releasing portion 6 of the dehumidifying rotor 7. The heater 15 faces the moisture release portion 6 on the front surface side of the main body case 1 of the dehumidifying rotor 7. That is, when viewed from the back side of the main body case 1, the heater 15 is located on the upper right side of the main body case 1 and on the upper right side of the dehumidifying rotor 7. The heat exchanger 16 is located on the left side of the main body case 1 when viewed from the back side of the main body case 1. And the electrostatic atomization means 19 is located in the upper left of the dehumidification rotor 7 located between the heat exchanger 16 and the moisture release part 6 of the dehumidification rotor 7. FIG.

  That is, the electrostatic atomizing means 19 is opposed to a part of the moisture absorption part 5, but in the rotation direction of the dehumidification rotor, it is separated from the heater 15 by more than a half circumference to the downstream side in the rotation direction of the dehumidification rotor. Radiant heat received from the dehumidifying rotor 7 can be suppressed.

  Further, the space between the electrostatic atomizing means 19 and the regeneration chamber 32 is larger than the space between the electrostatic atomizing means 19 and the heat exchanger 16. That is, since the space between the regeneration chamber 32 having a higher temperature than that of the heat exchanger 16 is large, the influence of heat from the regeneration chamber 32 and the heat exchanger 16 can be reduced.

  Further, as shown in FIG. 5, the second communication port 23 is configured to be positioned on the upper surface of the case portion 21. Specifically, the electrostatic atomizing means 19 includes a case portion 21 having a substantially vertical box shape having a first communication port 22 and a second communication port 23, and an electrostatic fog provided in the case portion 21. The generation unit 20 is formed. The case portion 21 is provided with a second communication port 23 on the upper surface of the case portion 21, and a first communication port 22 on the side surface on the dehumidification rotor 7 side. The second communication port 23 is an opening that communicates the inside of the case portion 21 and the space between the dehumidification rotor 7 and the intake port 2, and the first communication port 22 is a negative pressure provided in the casing 12. The opening communicates with the communication air passage 30 communicating with the generation hole 29. The negative pressure generating hole 29 is an opening provided in the casing 12, and the negative pressure generating hole 29 becomes negative pressure by rotating the blade 13 provided in the casing 12. That is, when the blades 13 provided in the casing 12 rotate, the room air sucked into the main body case 1 from the intake port 2 passes through the heat exchanger 16 of the moisture absorption path 14 or the moisture absorption part 5 of the dehumidification rotor 7. Thereafter, the air is exhausted from the exhaust port 3 to the outside of the main body case 1 as dehumidified air via the first air blowing means 9. At the same time, since the negative pressure generating hole 29 becomes negative pressure, the indoor air sucked into the main body case 1 from the air inlet 2 is the second communication port 23, the case portion 21, the first communication port 22, and the communication. It flows into the casing 12 through the negative pressure generating hole 29 via the ventilation path 30 and is exhausted out of the main body case 1 from the exhaust port 3 together with dehumidified air. Here, the charged fine particle water generated in the electrostatic atomization generating unit 20 rides on the airflow flowing in the case portion 21 from the second communication port 23 to the first communication port 22, and the main body from the exhaust port 3 together with dehumidified air. The air is exhausted outside the case 1.

  That is, since the second communication port 23 is located on the upper surface of the case portion 21, air heated by the radiant heat of the dehumidifying rotor 7 is unlikely to enter the case portion from the second communication port. Temperature rise can be suppressed. Thereby, it can suppress that the amount of the charged fine particle water which dew condensation by the discharge electrode 24 part and generate | occur | produces reduces.

  In addition, the airflow flowing from the second communication port 23 to the first communication port 22 flows between the electrostatic atomization generation unit 20 and the side surface portion of the case unit 21 on the dehumidification rotor 7 side, and from the dehumidification rotor 7. It is configured to flow outward. Specifically, the 2nd communicating port 23 is located in the dehumidification rotor 7 side of the upper surface of the case part 21, and the 1st communicating port 22 is located in the side surface by the side of the dehumidification rotor 7. FIG. Thereby, the airflow which flows from the 2nd communication port 23 to the 1st communication port 22 flows along the side surface by the side of the dehumidification rotor 7 of a case part. Here, both the first communication port 22 and the second communication port 23 are located outside the dehumidification rotor 7, and the flow path from the second communication port 23 to the first communication port 22 is also the dehumidification rotor. 7 is located on the outside.

  That is, the airflow that flows along the side surface of the case portion 21 on the dehumidification rotor 7 side, but the airflow flowing from the second communication port 23 to the first communication port 22 flows outside the dehumidification rotor 7. 7 is hardly affected by radiant heat. Thereby, it can suppress that the amount of the charged fine particle water which dew condensation by the discharge electrode 24 part and generate | occur | produces reduces.

  In addition, since the discharge electrode 24 of the electrostatic atomizing means 19 is opposed to the airflow flowing from the second communication port 23 to the first communication port 22 in the case portion 21, the discharge electrode 24 portion is cooled. The charged fine particle water generated by this is easily attracted to the airflow flowing from the second communication port 23 to the first communication port 22 in the case portion 21.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, a dehumidification rotor provided in the main body case and having a moisture absorbing portion and a moisture releasing portion, and air sucked from the intake port of the main body case. A first air blowing means for exhausting the air from the exhaust port to the outside of the main body case after passing through the hygroscopic portion of the dehumidification rotor by a first air passage, and a moisture absorption path provided in the main body case, The moisture absorption path circulates the moisture release part of the dehumidification rotor, the heater provided on the windward side of the moisture release part, the heat exchanger provided on the leeward side of the moisture release part, and the air in the moisture absorption path. The first air blowing means is formed from a scroll-shaped casing, blades provided in the casing, and an electric motor for rotating the blades, and the casing includes Equipped with a negative pressure generating hole, front A communication air passage that communicates the negative pressure generating hole and the electrostatic atomization means is provided, and the electrostatic atomization means includes a case portion having a first communication port and a second communication port, and the case portion. The electrostatic atomization generating section is provided, and the electrostatic atomization generating section is provided with a discharge electrode, a counter electrode disposed opposite to the discharge electrode, and a high voltage between the counter electrode and the discharge electrode. A high voltage marking portion for applying a voltage, a cooling portion for cooling the discharge electrode, and a radiation fin for radiating heat of the cooling portion, and the first communication port communicates with the communication air passage. The electrostatic atomizing means is positioned between the dehumidification rotor and the intake port in the air blowing path of the first air blowing means to further improve the amount of charged fine particle water generated by the electrostatic atomizing means. It is intended.

  That is, in the present invention, the electrostatic atomizing means is located between the dehumidification rotor and the intake port in the air blowing path of the second air blowing means. It is not heated by the moisture absorption part or the heat exchanger, but flows from the intake port to the radiation fin.

  For this reason, the generation amount of the charged fine particle water by the electrostatic atomizing means can be further improved.
