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

(Embodiment 1)
As shown in FIG. 1 and FIG. 2, the air purification apparatus of the present embodiment includes a main body case 1 having an air inlet 2 and an air outlet 3, and in the main body case 1, a blowing means 4, charged particulate water. , An ion generating means 6 for emitting ions having a polarity opposite to that of the charged fine particle water, and an air cleaning filter 7.

  The main body case 1 has a substantially box shape, and is provided with a horizontally elongated air outlet 3 on the upper surface and air intake ports 2 on the front surface and side surfaces.

  The air blowing means 4 is located in an air passage that connects the air inlet 2 and the air outlet 3 in the main body case 1, and has a scroll-shaped casing portion 8, a motor portion 9 fixed to the casing portion 8, and the motor The blade portion 10 is rotated by the portion 9.

  As shown in FIG. 3, the casing portion 8 includes a tongue piece forming surface 12 having a tongue piece 11, a tongue piece facing surface 13 opposed to the tongue piece forming surface 12, and the tongue piece forming surface 12 and the tongue piece facing. A first side surface 14 that connects both sides of the surface 13 and a second side surface 15 are formed. The first side surface 14 is provided with a circular suction port 16. The suction port 16 faces the front side of the main body case 1. On the top surface side of the main body case 1 of the casing portion 8, a horizontally elongated discharge port 17 surrounded by a tongue piece forming surface 12, a tongue piece facing surface 13, a first side surface 14, and a second side surface 15 is provided. Have. The blade portion 10 is a sirocco type.

  The electrostatic atomizing means 5 is provided in the discharge port 17 as shown in FIG. Specifically, the inside of the casing portion 8 is located in a space between the upper portion of the tongue piece forming surface 12 of the casing portion 8 and the main body case 1 through a communication path 18 extending from the tongue piece forming surface 12. Communicate. The charged fine particle water generated in the electrostatic atomization means 5 flows into the casing portion 8 through the communication path 18 and is blown from the blowout port 3 by the blower means 4.

  As shown in FIG. 4, the electrostatic atomization means 5 includes a discharge electrode 19, a counter electrode 20 disposed so as to face the discharge electrode 19, and a high voltage ( In this embodiment, a high voltage application unit 21 for applying 3.5 KV), a Peltier element 22 arranged as a cooling unit for cooling the discharge electrode 19, and a radiation fin 23 for radiating heat of the Peltier element 22 are provided. Yes.

  The Peltier element 22 applies a voltage of about 0.1 V to 2.8 V. In this embodiment, the discharge electrode 19 side is set to a low temperature, and the radiation fin 23 side is set to a high temperature. By cooling at the discharge electrode 19 portion, when dew condensation occurs, negatively charged charged fine particle water is generated.

  For this reason, negatively charged charged fine particle water is exhausted from the air outlet 3 to the outside of the main body case 1, and the negatively charged charged fine particle water contains active species such as hydroxyl radicals. When hydroxyl radicals in the charged fine particle water come into contact with bacteria or the like, the bacteria can be suppressed and sterilized by the oxidation action.

  The hydroxyl radical is a radical that reacts with a hydroxy group (hydroxyl group), and since this radical usually has only one electron that should be rotating in orbit in pairs, it is very unstable electrically. In order to take away the missing electrons from surrounding atoms and molecules, the oxidizing power is very strong, and the bacteria are suppressed and sterilized by this oxidizing action.

  The air purification filter 7 is provided in the air path between the air inlet 2 of the main body case 1 and the air blowing means 4.

  In the above configuration, the air purification operation will be described as shown in FIGS. Indoor air is sucked from the air inlet 2 of the main body case 1 by the air blowing means 4 and blown to the air cleaning filter 7. The air cleaning filter 7 collects dust and the like. The air in which the dust and the like are collected flows into the casing portion 8 of the air blowing means 4, and the charged fine particle water generated from the electrostatic atomizing means 5 and the ion generating means 6 are generated in the casing portion 8. Along with the positive ions, the air is blown out of the main body case 1 from the air outlet 3.

  Since the ion generating means 6 releases positive ions having a polarity opposite to that of the charged fine particle water, when the positive ions generated from the ion generating means 6 come into contact with the bacteria in the air, the bacteria in the air become charged fine particles. It has a polarity opposite to that of water and is positively charged. Negatively charged bacteria generated from the electrostatic atomization means 5 can easily come into contact with positively charged bacteria having a polarity opposite to that of the charged particulate water, and the contact probability can be increased.

  The feature of this embodiment is the configuration of the ion generating means 6 and the magnet 27.

  As shown in FIG. 5, the ion generating means 6 is located on the windward side of the electrostatic atomizing means 5 at the discharge port 17, and a rod-shaped discharge electrode 24 and a rod-shaped counter electrode extending in parallel with the discharge electrode 24. 25 and a high voltage application unit 26 that applies a high voltage (4.4 KV in this embodiment) to the discharge electrode 24 and the counter electrode 25. Positive ions are emitted from the tip of the discharge electrode 24 to which a high voltage is applied.

  Here, as shown in FIG. 6, the ion generating means 6 is located closer to the second side surface 15 of the casing portion 8, and the discharge electrode 24 is closer to the second side surface 15 side of the casing portion 8 than the counter electrode 25. The magnet 27 is provided between the discharge electrode 24 of the ion generating means 6 and the second side surface 15 of the casing portion 8 so as to be adjacent in the direction in which the discharge electrode 24 extends from the tip of the discharge electrode 24.

  That is, the ion generating means 6 is located closer to the second side surface 15 of the casing part 8, the discharge electrode 24 is provided closer to the second side surface 15 of the casing part 8 than the counter electrode 25, and the discharge electrode 24 and the casing part are provided. A magnet 27 is provided between the second side surface 15 and the eighth side surface 15 so as to be adjacent in the direction in which the discharge electrode 24 extends from the tip of the discharge electrode 24.

  Thus, since the discharge electrode 24 is provided on the second side surface 15 side of the casing part 8 from the counter electrode 25, a large amount of ions are directed from the discharge electrode 24 toward the first side surface 14 side of the casing part 8. Occur. Here, since the magnet 27 is provided between the discharge electrode 24 and the second side surface 15 of the casing portion 8 so as to extend in the direction in which the discharge electrode 24 extends from the tip of the discharge electrode 24, the casing is formed from the discharge electrode 24. The direction of generation of ions generated toward the first side surface 14 side of the portion 8 is further changed to the first side surface 14 side by the magnetic force of the magnet 27. Since the ion generating means 6 is located closer to the second side surface 15 of the casing portion 8, the ions generated from the ion generating means 6 are transmitted to the first side surface 14 of the casing portion 8 and the casing portion 8. It becomes easy to pass between the second side surfaces 15. That is, the contact with the first side surface 14 and the second side surface 15 of the casing portion 8 is suppressed.

  These results can further improve the ability of bacteria to suppress.

  Further, the tongue piece forming surface 12 is provided with a recessed portion 28 that is recessed outward from the casing portion 8, and the discharge electrode 24, the counter electrode 25, and the magnet 27 of the ion generating means 6 are provided in the recessed portion 28. Is.

  That is, since the ion generating means 6 and the magnet 27 are located in the hollow portion 28 that is recessed outward from the casing portion 8, it is possible to prevent the air blown by the air blowing means 4 from directly hitting the ion generating means 6 and the magnet 27. Therefore, the blowing resistance by the ion generating means 6 and the magnet 27 can be reduced.

  In addition, the discharge port 17 of the casing portion 8 opens upward, and the tongue piece forming surface 12 has an inclined surface 31 that is inclined obliquely upward so that the air passage is widened from the tongue piece 11 toward the 17 discharge port. Have. The inclined surface 31 is provided with a recess 28.

  The dent portion 28 includes a first dent portion 29 and a second dent portion 30. The first recess 29 is a substantially quadrangular prism-shaped space that is recessed in the horizontal direction from the tongue piece forming surface 12 toward the right side surface, which is the one side surface of the main body case 1. The second recessed portion 30 is a space that is downward from the lower surface of the first recessed portion 29 on the tongue piece forming surface 12 side and is recessed toward the tongue piece forming surface 12. The first depression 29 has the ion generating means 6 and the magnet 27.

  The magnet 27 is an upper part of the second depression 30 and is located on the second side 15 side, that is, on the side of the first depression 29 on the back side of the main body case 1 and has a triangular plate shape. The magnet 27 is a flat plate-shaped isotropic magnet, and the N pole and the S pole are adjacent to each other in the plane direction. Thereby, a magnetic field and an electric current are generated in the surface direction of the magnet 27, and a force is generated in a direction perpendicular to the plane of the magnet 27. Due to the force generated in the vertical direction, the ion generation direction changes.

  The ion generating means 6 is positioned outside the casing part 8 from the second depression part 30 in the first depression part 29, that is, behind the first depression part 29. The discharge electrode 24 and the counter electrode 25 of the ion generating means 6 extend from the back of the first depression 29 in the direction of the inclined surface 31, and the discharge electrode 24 and the counter electrode 25 are positioned in parallel in the horizontal direction. The discharge electrode 24 is provided on the second side surface 15 side of the casing portion 8 from the counter electrode 25, that is, on the back side of the main body case 1. When viewed from above in the main body case 1, the opening of the second recess 30 can be seen, but the discharge electrode 24 and the counter electrode 25 cannot be seen.

  Thereby, the ion generating means 6 is provided from the second side surface 15, and is provided with the recessed portion 28 in the inclined surface 31 of the tongue piece forming surface 12 in the casing portion 8. By this, the air of the hollow part 28 is attracted. That is, positive ions generated by the ion generating means 6 of the first dent 29 that is the dent 28 are also attracted and blown into the casing 8. Here, the blade portion 10 is a sirocco type, and the air flowing in the casing portion 8 is air flowing along the second side surface 15 as compared to air flowing along the first side surface 14 having the suction port 16. Since the air volume is considered to be larger, positive ions generated by the ion generating means 6 of the first recess 29 that is the recess 28 are considered to be attracted to the second side surface 15.

  Therefore, since the discharge electrode 24 is provided on the second side surface 15 side of the casing part 8 from the counter electrode 25, a large amount of positive ions are generated from the discharge electrode 24 toward the first side surface 14 side of the casing part 8. To do. Here, a magnet 27 is provided between the discharge electrode 24 and the second side surface 15 of the casing portion 8, on the second side surface 15 side of the first recess portion 29, on the second recess portion 30. Therefore, ions generated from the discharge electrode 24 toward the first side surface 14 of the casing portion 8 generate a magnetic field and current in the magnetic force of the magnet 27, that is, in the plane direction of the magnet 27. When a force is generated in a direction perpendicular to the plane, the generation direction is further changed to the first side surface 14 side.

  Thereby, the ions generated from the ion generating means 6 easily pass between the first side surface 14 of the casing portion 8 and the second side surface 15 of the casing portion 8. That is, the contact with the first side surface 14 and the second side surface 15 of the casing portion 8 is suppressed.
