(Embodiment 1)
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIGS. 1 and 2, the ion generator of this embodiment includes a first air blowing means 2 and an ion generating means 3 in a main body case 1.

  The main body case 1 has a substantially vertically long box shape, and is provided with a first intake port 4 and a second intake port 5 each having a substantially rectangular shape on the side surface on the back side of the main body case 1. A substantially rectangular exhaust port 6 is provided.

  The first air blowing means 2 is provided in an air passage between the first air inlet 4 and the air outlet 6 of the main body case 1, and has a scroll-shaped first casing 7 and an inside of the first casing 7. The first blade 8 provided on the first blade 8 and the first electric motor 9 that rotates the first blade 8 are formed. The air blown into the main body case 1 from the first air inlet 4 is blown to the air outlet 6 by the first air blowing means 2. As shown in FIGS. 2 and 3, the first casing 7 of the first air blowing means 2 is opposed to the first tongue piece forming surface 11 having the tongue piece 10 and the first tongue piece forming surface 11. A first tongue piece facing surface 12, a first side surface 13 connecting the first tongue piece forming surface 11 and both sides of the first tongue piece facing surface 12, and a second side surface 14. Yes.

  A feature of the present embodiment is that the first tongue piece facing surface 12 is provided with a negative pressure generating hole 15, the ion generating means 3 is provided outside the first casing 7 of the negative pressure generating hole 15, and the second This is the point that a blower passage 16 is formed from the intake port 5 to the ion generating means 3, the negative pressure generating hole 15, the first casing 7, and the exhaust port 6. Here, the air blown into the main body case 1 from the first air inlet 4 by the first air blowing means 2 is blown to the air outlet 6, thereby facing the first tongue piece in the first casing 7. Since the negative pressure generating hole 15 becomes negative pressure due to the airflow flowing through the surface 12, the indoor air passes from the second air inlet 5, which is the air blowing path 16, through the ion generating means 3 and the negative pressure generating hole 15. Then, the air flows into the first casing 7 and is blown by the first blowing means 2 to the exhaust port 6 together with the air sucked into the main body case 1 from the first intake port 4. Thus, negative ions generated by the ion generating means 3 are blown into the room from the exhaust port 6 by the first blowing means 2.

  That is, in the present invention, the negative pressure generating hole 15 is provided on the first tongue piece facing surface 12 facing the tongue piece 10 of the first casing 7, and the negative pressure generating hole 15 is provided outside the first casing 7. An ion generating means 3 is provided, and a blower passage 16 is formed from the second intake port 5 to the ion generating means 3, the negative pressure generating hole 15, the first casing 7, and the exhaust port 6. That is, since the ion generating means 3 is not provided in the air passage in the first casing 7 but is provided outside the first casing 7, the turbulence of the air blowing in the first casing 7 by the ion generating means 3 is suppressed. It is something that can be done.

  With these results, it is possible to reduce the blowing sound generated by the disturbance of the blowing in the casing.

  In the present invention, the ion generating means 3 is taken out of the first casing 7, and the ion generating means 3 is fixed to the first casing 7 through the negative pressure generating hole 15 provided in the first casing 7. By doing so, the main body case 1 can be reduced in size.

  The first casing 7 includes a first tongue piece forming surface 11 having a tongue piece 10, a first tongue piece facing surface 12 opposed to the first tongue piece forming surface 11, and the first tongue piece forming surface 11. Ion generation is provided by providing a first air outlet 17 surrounded by a first side surface 13 and a second side surface 14 connecting both sides of the tongue piece forming surface 11 and the first tongue piece facing surface 12 and opening upward. The means 3 is configured to be located above the negative pressure generating hole 15. Specifically, the ion generating means 3 may be anything that generates at least negative ions.

  A negative pressure generating hole 15, which is a substantially elliptical opening communicating the ion generating means 3 and the inside of the first casing 7, is located below the ion generating means 3. An example of the ion generating means 3 will be described as the electrostatic atomizing means 20. As shown in FIG. 4, the electrostatic atomizing means 20 includes a discharge electrode 21, a counter electrode 22 disposed to face the discharge electrode 21, and a high voltage between the counter electrode 22 and the discharge electrode 21. (In this embodiment, −5 KV), a Peltier element 24 arranged as a cooling part for cooling the discharge electrode 21, and a radiation fin 25 for radiating heat of the Peltier element 24. ing.

  The Peltier element 24 applies a voltage of about 0.75 V to 2.8 V. In this embodiment, the discharge electrode 21 side is set to a low temperature, and the radiation fin 25 side is set to a high temperature.

  Therefore, the indoor air that passes through the air blowing path 16 is cooled by the discharge electrode 21 portion, and when dew condensation occurs, charged fine particle water is generated.

  For this reason, the charged fine particle water is then exhausted from the exhaust case 6 together with the dry air to the outside of the main body case 1, and the hydroxyl radicals in the charged fine particle water react with the odor and oxidize it to decompose the odor. It can be done.

  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 missing electrons from surrounding atoms and molecules, the oxidizing power is very strong, and the odor is decomposed and removed by this oxidizing action.

  That is, since the ion generating means 3 is located above the negative pressure generating hole 15, water accidentally enters from the exhaust port 6 of the main body case 1, and the first tongue piece facing surface 12 of the first casing 7 is moved. Even when it is transmitted and flows into the negative pressure generating hole 15, water does not flow into the ion generating means 3, so that failure of the ion generating means 3 due to water can be suppressed.

  Further, a part of the first tongue piece facing surface 12 is inclined toward the tongue piece 10 so that a space 18 is provided between the first tongue piece facing surface 12 and the side surface of the main body case 1. The ion generating means 3 is provided in the space 18. Specifically, the first tongue piece facing surface 12 is inclined to the tongue piece 10 side by the first tongue piece facing surface 12 positioned in the upper portion from the substantially central portion of the first casing 7 in the vertical direction. Between the surface 12 and the side surface of the main body case 1, a cross-sectional shape in the direction of the first side surface 13 forms a substantially triangular space 18. The space 18 is provided with the ion generating means 3.

  That is, by inclining a part of the first tongue piece facing surface 12 toward the tongue piece 10, the space 18 for providing the ion generating means 3 can be formed outside the first casing 7. Without increasing 1, the ion generating means 3 can be provided outside the first casing 7.

  Further, the negative pressure generating hole 15 is located in the flat portion 12 a of the first tongue piece facing surface 12 of the first casing 7. Specifically, a planar portion 12a having a planar shape is located on the first tongue piece facing surface 12 located in the upper portion from the substantially central portion of the first casing 7 in the vertical direction, and negative pressure is applied to the planar portion 12a. The generation hole 15 is provided.

  That is, since the negative pressure generating hole 15 is provided in the flat surface portion 12a having a planar shape, the air flow in the vicinity of the negative pressure generating hole 15 in the first casing 7 is rectified by the flat surface portion 12a and is opened at the opening. A certain negative pressure generating hole 15 can generate a more stable negative pressure.

  As shown in FIGS. 3 and 5, an air volume distribution changing means 19 is provided in the vicinity of the first air outlet 17 of the first casing 7, and the air volume distribution changing means 19 is provided on the tongue piece 10 of the first casing 7. It is a curved rectangular plate that is convex in the direction, and is formed substantially in parallel with the wind direction blown out from the first blade 8. Specifically, the air volume distribution changing means 19 is provided at the first air outlet 17, and the air volume distribution changing means 19 is a curved rectangular plate and has a convex shape in the direction of the tongue piece 10 of the first casing 7. The air blowing means 2 is provided substantially in parallel with the wind direction blown out from the first blade 8. Thereby, the air blown out from the first blade 8 is the air volume distribution changing means 19 at the first air outlet 17 of the first casing 7 with the curved rectangular plate as the air volume distribution changing means 19 as a boundary. Tongue piece side air flow 28 which is an air flow flowing between the curved rectangular plate and the first tongue piece forming surface 11 of the first casing 7, and the curved rectangular plate and the first tongue piece as the air volume distribution changing means 19. The airflow is divided into a tongue-facing side airflow 29 that is an airflow flowing between the facing surface 12. Here, a part of the tongue piece-side air flow 28 changes its direction toward the tongue piece 10 side by hitting the convex portion 19a which is convex in the direction of the tongue piece 10 of the first casing 7 of the curved rectangular plate. . Further, a part of the airflow 29 on the tongue-facing side strikes the windward end 19c of the curved rectangular plate, and air vortices are generated in the vicinity of the windward end 19c of the curved rectangular plate. 27 occurs. Since a part of the turbulent flow portion 27 flows along the concave portion 19b that is the concave shape of the first tongue piece facing surface 12, it flows while spreading in the direction of the tongue piece 10 of the first casing 7. That is, the airflow 29 on the tongue-facing side flows on the scroll side wall side of the first tongue-facing surface 12 of the first casing 7 and the turbulent flow portion 27 generated near the windward end 19c of the curved rectangular plate. It is thought that it is divided into the scroll side wall side air flow part 29a.

  Thereby, the air volume distribution changing means 19 is provided in the vicinity of the first air outlet 17 of the first casing 7, and the air volume distribution changing means 19 is a curved rectangle that is convex in the direction of the tongue piece 10 of the first casing 7. Since the plate is provided substantially parallel to the direction of the air blown from the first blade 8, the negative ions generated by the ion generating means 3 are generated from the negative pressure generating hole 15 of the first tongue piece facing surface 12 through the first pressure generating hole 15. The air flows into the casing 7 and is blown into the room from the exhaust port 6 while spreading in the direction of the tongue piece 10 of the first air outlet 17 by the turbulent flow portion 27 generated in the vicinity of the windward end portion 19c of the curved rectangular plate. As a result, negative ions generated by the ion generating means 3 from a wide range of the exhaust port 6 can be blown into the room.

  Further, the negative pressure generating hole 15 is configured to be located on the wind path upstream side of the air volume distribution changing means 19 in the vicinity of the first air outlet 17 of the first casing 7. Specifically, the negative pressure generating hole 15 is located on the wind path windward side from the windward side end portion 19 c of the curved rectangular plate which is the air volume distribution changing means 19.

  Thereby, since the negative pressure generating hole 15 is provided on the wind path upstream side of the air volume distribution changing means 19 in the vicinity of the first outlet 17 of the first casing 7, the negative ions generated by the ion generating means 3 are The air flows into the first casing 7 from the negative pressure generating hole 15 of the first tongue facing surface 12 and is blown into the room from the exhaust port 6 while spreading in the direction of the tongue 10 of the first air outlet 17. As a result, negative ions generated by the ion generating means 3 can be blown into the room from a wider range of the exhaust port 6.
