(Embodiment 1)
An embodiment of the present invention will be described below 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. The main body case 1 is provided with a substantially square-shaped intake port 4 on the side surface on the back side thereof, and a substantially square-shaped exhaust port 5 is provided on the top surface of the main body case 1. Yes. The exhaust port 5 is provided with a wind direction louver 6.

  The first air blowing means 2 is provided in the air passage between the air inlet 4 and the air outlet 5 of the main body case 1, and is provided in the scroll-shaped first casing 7 and the first casing 7. The first blade 8 is a centrifugal blower fan, and a first electric motor 9 that rotates the first blade 8 is formed. The air blown into the main body case 1 from the intake port 4 is blown to the exhaust port 5 by the first blowing means 2.

  As shown in FIGS. 2 and 3, the first casing 7 of the first blower means 2 includes a first suction side surface 10, a first suction facing side surface 11 that faces the first suction side surface 10, and The first tongue side scroll surface 12 and the first tongue piece opposite scroll surface 13 connecting the first suction side surface 10 and the first suction opposing side surface 11 are formed.

  The first suction side surface 10 includes a circular first suction port 14, and the first suction port 14 faces the suction port 4 of the main body case 1. The first tongue piece scroll surface 12 has a tongue piece portion 15 protruding inward of the first casing 7. The first tongue piece-facing scroll surface 13 is located opposite to the first tongue piece scroll surface 12. The upper portion of the first casing 7 is surrounded by a first suction side surface 10, a first suction facing side surface 11, a first tongue piece scroll surface 12, and a first tongue piece facing scroll surface 13. The first air outlet 16 opened upward is provided.

  The ion generating means 3 is located in the air path between the air inlet 4 of the main body case 1 and the first air inlet 14 of the first casing 7. One example of the ion generating means 3 will be described as the electrostatic atomizing means 17. As shown in FIG. 4, the electrostatic atomizing means 17 includes a discharge electrode 18, a counter electrode 19 disposed opposite to the discharge electrode 18, and a high voltage between the counter electrode 19 and the discharge electrode 18. A high voltage application unit 20 for applying (-5 KV in this embodiment), a Peltier element 21 arranged as a cooling unit for cooling the discharge electrode 18, and a radiation fin 22 for radiating the heat of the Peltier element 21. Yes. The Peltier element 21 applies a voltage of about 0.75 V to 2.8 V. In this embodiment, the discharge electrode 18 side is set to a low temperature, and the radiation fin 22 side is set to a high temperature.

  Therefore, when the room air passing through the air passage is cooled by the discharge electrode 18 portion and dew condensation occurs, charged fine particle water is generated.

  For this reason, the charged fine particle water is then exhausted together with the dry air from the exhaust port 5 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.

  The feature of the present embodiment is that the first suction side surface 10 that is upstream of the tongue piece portion 15 between the first tongue piece facing scroll surface 13 and the first blade 8 in the first casing 7 is The attraction means 23 is provided. As a result, the air blown into the main body case 1 by the first air blowing means 2 from the air inlet 4 via the first air inlet 14 and the first air outlet 16 of the first casing 7 is exhausted. To blow. And by this ventilation, the attracting means 23 attracts the air sucked into the main body case 1 from the air inlet 4 into the first casing 7 via the ion generating means 3. Here, as the air passage between the first tongue-facing scroll surface 13 and the first blade 8 gradually widens from the position of the attracting means 23 toward the first air outlet 16, this air passage The air that flows through the air also flows gradually. That is, the ions generated by the ion generating means 3 and attracted into the first casing 7 flow while gradually spreading while being blown from the attracting means 23 to the first outlet 16.

  As a result, the deviation in the blowing direction from the exhaust port 5 of ions generated from the ion generating means 3 can be reduced.

  Further, a wind direction louver 6 is provided at the exhaust port 5. As shown in FIG. 5, the wind direction louver 6 is a substantially flat louver portion 24 and includes a left end portion on the left and right sides of the main body case and a shaft portion 25 extending outward from the right end portion. The shaft portion 25 is rotatably mounted on the bearing portion 26 of the exhaust port 5. Thereby, the wind direction from the exhaust port 5 can be changed in the elevation direction from the horizontal direction to the vertical direction.

  However, when the wind direction louver 6 is rotated, the blast in the first casing 7 may be disturbed. Therefore, the attracting means 23 is provided on the first suction side surface 10 upstream of the tongue piece portion 15 between the first tongue piece facing scroll surface 13 and the first blade 8 in the first casing 7. Is. As a result, since the exhaust port 5 and the attracting means 23 are separated from each other by a predetermined distance, the first casing 7 is generated when the wind direction louver 6 provided at the exhaust port 5 is rotated. It is possible to reduce the influence of air turbulence. That is, the fluctuation amount of the amount of ions attracted by the attracting means 23 can be reduced. Further, the main body case 1 is provided with an electric motor (not shown) that rotates the wind direction louver 6 in the elevation direction from the horizontal direction to the vertical direction, and when the electric motor automatically rotates the first casing, This increases the number of cases where turbulence in the air occurs.

  In addition, as shown in FIG. 6, the attracting means 23 is formed of an opening 27 that is an opening and a negative pressure generating part 28 that is located around the opening 27. The opening 27 is a substantially rectangular opening and is located on the first suction side surface 10 between the first tongue-facing scroll surface 13 and the first blade 8 in the first casing 7. And the first tongue-facing scroll surface 13 have a predetermined distance, and the opening 27 and the first blade 8 also have a predetermined distance.

  The negative pressure generator 28 is located upstream of the opening 27 in the air blowing direction in the first casing 7, and protrudes inward from the first suction side surface 10 to the first casing 7. 29. The first protrusion 29 has an inclined surface 30 that inclines from the first suction side surface 10 toward the inside of the first casing 7 as it goes from the upstream side to the downstream side in the air blowing direction in the first casing 7. I have.

  Specifically, the first protrusion 29 includes a horizontal plane 31 extending horizontally from the lower end of the opening 27 inward of the first casing 7, and a first suction downward from the tip of the horizontal plane 31. The inclined surface 30 is inclined and extended toward the side surface 10, and both sides 32 of a right triangle connected to both ends of the inclined surface 30 from both ends of the horizontal surface 31.

  That is, a part of the air flowing between the first tongue-facing scroll surface 13 and the first blade 8 in the first casing 7 flows along the inner surface of the first suction side surface 10, and the opening portion. The airflow flows along the inclined surface 30 from 27 before. This air flow has a predetermined distance from the opening 27 and flows from the upper end of the inclined surface 30 toward the first outlet 16. That is, a negative pressure region that is a negative pressure is generated between the air flow and the opening 27, and ions generated from the ion generating means 3 from the opening 27 can be attracted by the negative pressure region.

  Further, ions that have a predetermined distance from the opening 27 and are attracted by the airflow flowing from the upper end of the inclined surface 30 toward the first outlet 16 are blown out from the exhaust port 5 by riding on this airflow. In other words, since it is considered that the first suction side surface 10 is blown from the exhaust port 5 by riding on an airflow flowing at a distance from the first suction side surface 10, it is possible to suppress a decrease in ions due to charging of the first suction side surface 10.

  Moreover, since the 1st suction opposing side surface 11 and the 1st suction side surface 10 are parallel, the distance of the upper end of the inclined surface 30 and the 1st suction opposing side surface 11 is the lower end of the inclined surface 30, and 1st suction surface. The wind speed flowing from the upper end of the inclined surface 30 toward the first outlet 16 becomes shorter than the distance from the suction facing side surface 11. That is, since the negative pressure region between the air flow and the opening 27 becomes a more negative pressure, ions generated from the ion generating means 3 from the opening 27 can be further attracted.

(Embodiment 2)
Hereinafter, the ion generator in Embodiment 2 of this invention is demonstrated, referring drawings. In addition, about the thing which has the structure similar to the structure of Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 7, the difference from the first embodiment is that, on the downstream side of the first protrusion 29 in the air blowing direction in the first casing 7, the first casing 10 extends from the first suction side 10. Two second projecting portions 33 projecting inward of the first casing 7 are provided, and these second projecting portions 33 are provided in the first casing 7 from the downstream end portion of the inclined surface 30 in the air blowing direction. 7 has two vertical surfaces 34 extending from the upstream side to the downstream side in the air blowing direction, and the vertical surface 34 is parallel to the first suction side surface 10 and positioned so as to sandwich the opening 27. This is the point.

  Specifically, the 2nd protrusion part 33 is the cube shape extended from the both ends of the horizontal surface of the 1st protrusion part 29 to the downstream in the ventilation direction in a casing. The surface of the second protrusion 33 that faces the first suction facing side surface 11 is a vertical surface 34. The vertical surface 34 is connected to the inclined surface 30 of the first protrusion 29. The opening 27 is located between the two second protrusions 33.

  That is, a part of the air flowing between the first tongue-facing scroll surface 13 and the first blade 8 in the first casing 7 flows along the inner surface of the first suction side surface 10, and the opening portion. The airflow flows along the inclined surface 30 of the first projecting portion 29 from before 27. One part of this airflow further flows along the vertical surfaces 34 of the two second protrusions 33, and the airflow flowing between them also has a predetermined distance from the opening 27, from the upper end of the inclined surface 30. It flows in the direction of the first outlet 16. Here, since the first suction facing side surface 11 and the first suction side surface 10 are parallel, the distance between the vertical surface 34 of the second protrusion 33 and the first suction facing side surface 11 is the inclined surface 30. The distance between the lower end of the first suction facing side surface 11 and the first suction facing side surface 11 is shorter, and the speed of the wind flowing in the direction of the first air outlet 16 on the vertical surface 34 of the second protrusion 33 becomes faster. That is, the two airflows flowing along the vertical surfaces 34 of the two second protrusions 33 also increase the speed of the airflow that flows opposite to the opening 27 between them, and as a result, the opening 27 Since the negative pressure region between the airflow flowing in opposition and the opening 27 becomes more negative, ions generated from the ion generating means 3 can be more attracted from the opening 27.

  The two surfaces extending from the upstream side to the downstream side in the air blowing direction in the first casing 7 from the both side surfaces 32 of the first projecting portion 29 are the both side surfaces 35 of the second projecting portion 33. That is, the airflow flowing along the both side surfaces 32 of the first projecting portion 29 further flows along the both side surfaces 35 of the second projecting portion 33 and flows in the direction of the first outlet 16. That is, the second protrusion 33 can suppress the airflow flowing along the both side surfaces 32 of the first protrusion 29 from flowing into the opening 27.

  The vertical surface 34 of the second protrusion 33 extends to the downstream end of the opening 27 in the blowing direction in the first casing 7. Specifically, the vertical surface 34 of the second protrusion 33 is located from the upstream end to the downstream end of the opening 27 in the blowing direction in the first casing 7.

  In addition, the length of the inclined surface 30 of the first protrusion 29 in the air blowing direction in the first casing 7 is from the inner surface of the first suction side surface 10 of the first protrusion 29 to the inside of the first casing 7. The length is longer than the length protruding in the direction. Specifically, the inclined surface 30 is inclined from the first suction side surface 10 to the inside of the first casing 7 as it goes from the upstream side to the downstream side in the blowing direction in the first casing 7. . Here, the angle between the first suction side surface 10 and the inclined surface 30 inclined from the first suction side surface 10 is an acute angle.

  That is, a part of the air flowing between the first tongue-facing scroll surface 13 and the first blade 8 in the first casing 7 flows along the first suction side surface 10, and the opening 27 The airflow flows along the inclined surface 30 of the first protrusion 29 from the front. Here, since the angle between the first suction side surface 10 and the inclined surface 30 inclined from the first suction side surface 10 is an acute angle, generation of turbulent flow can be suppressed.

(Embodiment 3)
Hereinafter, an ion generation apparatus according to Embodiment 3 of the present invention will be described with reference to the drawings. In addition, about what has the structure similar to the structure of Embodiment 1 and 2, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIGS. 8 and 9, the difference from the second embodiment is that a dehumidifying means 36 is provided in the main body case 1, and this dehumidifying means 36 is an air flow between the air inlet 4 and the first air blowing means 2. This is a point of dehumidifying the road.

  The dehumidifying means 36 includes a dehumidifying rotor 39 having a moisture absorbing part 37 and a moisture releasing part 38, and a moisture absorbing path 40. The moisture absorbing path 40 is provided on the moisture releasing part 38 of the dehumidifying rotor 39 and on the windward side of the moisture releasing part 38. The heater 41 provided, the heat exchanger 42 provided on the leeward side of the moisture release section 38, and the second air blowing means 43 for circulating the air in the moisture absorption path 40 are provided. The moisture absorbing portion 37 of the dehumidifying rotor 39 is provided in the air passage between the air blowing means 2 and the air blowing means 2. More specifically, in FIG. **, there is an intake port 4 on the back side of the main body case 1 and an exhaust port 5 on the upper side, and a receiving tray 44 is provided below the front surface of the main body case 1 so as to be able to appear and retract. It has been.

  Further, a dehumidifying rotor 39 having a moisture absorbing portion 37 and a moisture releasing portion 38 is rotatably arranged in the main body case 1, and the rotation drive is performed by a motor 45.

  Further, as indicated by an arrow A in FIG. 1, indoor air sucked from the air inlet 4 of the main body case 1 passes through the moisture absorbing portion 37 of the dehumidifying rotor 39 and then passes from the exhaust port 5 to the front of the main body case 1. The 1st ventilation means 2 exhausted out of the case 1 is provided.

  The first air blowing means 2 is provided in the first casing 7 having a first suction port 14 on the back side, a first casing 7 having an upper first air outlet 16 shown in FIG. The indoor air after passing through the moisture absorbing portion 37 of the dehumidifying rotor 39 is supplied from the first suction port 14 to the first air inlet 8 having the first blade 8 and the first electric motor 9 that drives the first blade 8. 1 flows into the casing 7, is pressurized by the first blade 8, and is exhausted out of the main body case 1 through the first outlet 16 and the exhaust outlet 5 as shown in FIG. 3.

  Further, as shown in FIG. 8, a moisture absorption path 40 is provided in the main body case 1, and the moisture absorption path 40 is provided on the moisture release portion 38 of the dehumidification rotor 39 and on the windward side of the moisture release portion 38. The heater 41, the heat exchanger 42 provided on the leeward side of the moisture release section 38, and the second air blowing means 43 for circulating the air in the moisture absorption path 40 are provided. The moisture absorption path 40 is independent as a ventilation path in the main body case 1.

  Further, in the main body case 1, as indicated by an arrow B in FIG. 7, the indoor air sucked into the main body case 1 from the intake port 4 by the first air blowing means 2 passes through the heat exchanger 42 of the moisture absorption path 40. Thereafter, an air passage for exhausting air from the exhaust port 5 to the outside of the main body case 1 is formed via the first air blowing means 2.

  However, the indoor air indicated by the arrow B is only heat-exchanged with the air in the moisture absorption path 40 passing through the heat exchanger 42 through the heat conduction surface constituting the heat exchanger 42. It is not mixed in 42 parts.

  Here, the operation of the moisture absorption path 40 will be described. The air in the moisture absorption path 40 heated by the heater 41 is dehumidified in the moisture release section 38 (this moisture release section 38 when the moisture absorption section 37 of the dehumidification rotor 39 rotates). Moisture is released, and this high-temperature and excessively humid air is sent to the heat exchanger 42 on the leeward side.

  As described above, since the indoor air is blown to the heat exchanger 42 by the first air blowing means 2 as shown by the arrow B, the high-temperature and excessively humid air is cooled and thereby condensed. It is stored in the tray 44.

  The moisture absorbing portion 37 of the dehumidifying rotor 39 adsorbs moisture every time indoor air passes as indicated by an arrow A, and this becomes the moisture releasing portion 38 described above by the rotation of the dehumidifying rotor 39 and becomes the moisture absorbing path 40. Moisture is released into the interior, and the indoor air is dehumidified by such circulation.

  The ion generating means 3 is located in the air path between the air inlet 4 of the main body case 1 and the dehumidifying rotor 39 and faces the air inlet 4 of the main body case 1. The ion generating means 3 communicates with the attracting means 23 of the first air blowing means 2 through a communication air passage 46.

  Thereby, the first air blowing means 2 dehumidifies the indoor air sucked into the main body case 1 from the air inlet 4 by the moisture absorbing portion 37 of the dehumidifying rotor 39, and the first air inlet 14 of the first casing 7, The air is blown to the exhaust port 5 through the first air outlet 16. And by this ventilation, the attracting means 23 attracts the air sucked into the main body case 1 from the air inlet 4 into the first casing 7 via the ion generating means 3. The ion generating means 3 generates charged fine particle water that is ions from the indoor air that has flowed in. Here, as the air passage between the first tongue-facing scroll surface 13 and the first blade 8 gradually widens from the position of the attracting means 23 toward the first air outlet 16, this air passage The air that flows through the air also flows gradually. That is, the ions generated by the ion generating means 3 and attracted into the first casing 7 flow while gradually spreading while being blown from the attracting means 23 to the first outlet 16.

  As a result, since the ions generated from the ion generating means 3 can be blown evenly from the exhaust port 5, when the blown air is blown to the laundry and the laundry is dried, the laundry can be uniformly deodorized.

  Further, a wind direction louver 47 is provided at the exhaust port of the main body case 1 so as to be rotatable.

  The wind direction louver 47 has a substantially flat plate shape and includes a left end portion on the left and right sides of the main body case 1 and a shaft portion 48 extending outward from the right end portion. This shaft portion 48 is rotatably mounted on a bearing portion 49 of the exhaust port. Thereby, the wind direction from the exhaust port 5 can be changed in the elevation direction from the horizontal direction to the vertical direction.

  However, when the wind direction louver 47 is rotated, the air blow in the first casing 7 may be disturbed. Therefore, the attracting means 23 is provided on the first suction side surface 10 upstream of the tongue piece portion 15 between the first tongue piece facing scroll surface 13 and the first blade 8 in the first casing 7. Is. Accordingly, since the exhaust port 5 and the attracting means 23 are separated from each other by a predetermined distance, the air blow in the first casing 7 generated when the wind direction louver 47 provided at the exhaust port 5 is rotated. The influence of disturbance can be reduced. That is, the fluctuation amount of the amount of ions attracted by the attracting means 23 can be reduced.

  As a result, even when the wind direction louver 47 is rotated to change the wind direction and the laundry is dried, the amount of fluctuation of the amount of ions attracted by the attracting means 23 can be reduced, so that the laundry can be deodorized.

(Embodiment 4)
Hereinafter, an ion generation apparatus according to Embodiment 4 of the present invention will be described with reference to the drawings. In addition, about the thing which has the structure similar to the structure of Embodiment 1, 2, and 3, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The difference from the third embodiment is that a wind direction louver rotating means for reciprocally rotating the wind direction louver 47 is provided in the main body case 1 as shown in FIG. Specifically, the wind direction louver rotating means is the electric motor 50. The electric motor 50 is connected to the shaft portion 48 of the wind direction louver 47 to reciprocately rotate the wind direction louver 47 from the horizontal direction to the vertical direction.

  As described above, when the wind direction louver 47 is reciprocally rotated, the air flow is disturbed by the pressure change in the first casing 7. Therefore, the attracting means 23 is provided on the first suction side surface 10 upstream of the tongue piece portion 15 between the first tongue piece facing scroll surface 13 and the first blade 8 in the first casing 7. Is. As a result, since the exhaust port 5 and the attracting means 23 are separated from each other by a predetermined distance, the first casing 7 is generated when the wind direction louver 47 provided in the exhaust port 5 is reciprocally rotated. The influence of turbulence in the air can be reduced. That is, the fluctuation amount of the amount of ions attracted by the attracting means 23 can be reduced.

  As a result, even when the wind direction louver 47 is reciprocally rotated to change the wind direction and dry the laundry, the amount of variation in the amount of ions attracted by the attracting means 23 can be reduced, so that the laundry can be deodorized. .

As described above, the present invention includes a main body case having an intake port and an exhaust port, and a first air blowing unit and an ion generating unit provided in the main body case, and the first air blowing unit has a scroll shape. A first casing, a first blade provided in the first casing, and a first electric motor that rotates the first blade, the first casing being a first suction port A first suction side surface provided with a first suction side surface facing the first suction side surface, and a tongue piece portion connecting the first suction side surface and the first suction side surface. A tongue scroll surface and a first tongue-facing scroll surface facing the first tongue scroll surface, a first suction-facing side surface, a first suction side surface, and a first tongue piece A first blower surrounded and opened by the scroll surface and the first tongue-facing scroll surface. The ion generating means is located in an air path between the air inlet of the main body case and the first air inlet of the first casing, and the first air blowing means sucks air into the main body case from the air inlet. The blown air is blown to the exhaust port through the first suction port and the first blower port of the first casing, and the air sucked into the main body case from the suction port by the blown air is passed through the ion generating means. An attraction means for attracting the first casing is provided, and the attraction means is upstream of the tongue portion between the first tongue-facing scroll surface and the first blade in the first casing. 1 is configured to be located on the suction side surface,
It is possible to reduce the deviation in the blowing direction of ions generated from the ion generating means.

  That is, the attracting means is located on the first suction side surface, which is upstream from the tongue piece portion between the first tongue-facing scroll surface and the first blade in the first casing. Here, the air path between the first tongue-facing scroll surface and the first blade gradually widens from the position of the attraction means toward the first air outlet, and the air flowing through the air path gradually increases. It flows while spreading. That is, the ions generated by the ion generating means and attracted into the first casing flow while gradually spreading while being blown from the attracting means to the first outlet.

  As a result, the deviation in the blowing direction of ions generated from the ion generating means can be reduced.

  Therefore, it is expected to be used as an ion generating means for home use and office use.
