FIG. 4 is a graph showing a change in the cross-sectional area of the open portion of the positive ion passage. In addition, FIG. 3 shows the state which looked at the air conditioner from the top.

  The air conditioner according to the present invention has a suction port 1 on a lower side surface of a vertically long rectangular parallelepiped housing 10, and a fan (blower) 2 that sucks air from the suction port 1 and blows the air upward is provided inside the housing 10. Provided.

  A cylindrical duct 3 that forms an upward ventilation path is provided on the upper side of the fan 2, and the duct 3 protrudes inward at the upper and lower central portions and has a narrow cross-sectional area. A partition plate 5 is provided from the vicinity of the lower end of the upper and lower central portion of the duct 3 to the upper surface of the housing 10 to partition the ventilation path having a circular cross section to the left and right.

  An ion generator 6 including a positive ion generator 6A and a negative ion generator 6B is installed at the upper and lower central portions in the duct 3. The ion generator 6 includes positive and negative ion generators 6A and 6B each having an annular induction electrode 62 provided in a hole formed on a flat and elongated substrate 61, and a needle electrode 63 positioned at the center of the induction electrode 62. 2 each. The positive ion generator 6A is located in one semicircular positive ion passage 4A partitioned by the partition plate 5, and the negative ion generator 6B is the other semicircular negative ion passage partitioned by the partition plate 5. Located in 4B. The positive ion generator 6A and the negative ion generator 6B are juxtaposed in a direction crossing the circular ventilation passage, and the surface of the substrate 61 serving as an ion emission surface is arranged in parallel with the airflow direction in each of the passages 4A and 4B. ing.

  In the positive ion generator 6A, positive ions are generated by applying a positive high voltage or a positively biased AC impulse voltage between the induction electrode 62 and the needle electrode 63. In the negative ion generator 6B, Negative ions are generated by applying a negative high voltage or a negatively biased AC impulse voltage between the induction electrode 62 and the needle electrode 63. The positive ion generator 6A sends positive ions into the positive ion passage 4A, and the negative ion generator 6B sends negative ions into the negative ion passage 4B.

  On the windward side of the positive ion generator 6A and the negative ion generator 6B, an elliptical plate-like damper 7 is installed so that the plate surface is orthogonal to the axial direction of the duct 3. The damper 7 has a rotation axis 7A along the axial direction of the duct 3 at a position where the length of the major axis of the ellipse is slightly shorter than the diameter of the circular cross section of the ventilation path and is eccentric from the center of the ellipse in the minor axis direction. . The rotary shaft 7A is pivotally supported by a bearing (not shown) provided at the edge of the partition plate 5. When the damper 7 rotates around the rotation axis 7A, the cross-sectional areas of the positive ion passage 4A and the negative ion passage 4B blocked by the damper 7 are changed (see FIG. 3).

  A positive ion outlet 8A and a negative ion outlet 8B are provided separately on the upper surface of the housing 10, and the upper end of the positive ion passage 4A communicates with the positive ion outlet 8A, so that a negative ion passage is provided. The upper end of 4B communicates with the negative ion outlet 8B. Ion detectors 9 are installed on the inner walls of the positive ion outlet 8A and the negative ion outlet 8B, respectively.

  Next, the operation of the air conditioner according to the present invention will be described. When the fan 2 rotates, the air sucked from the suction port 1 is blown upward, passes through the inflow portion not blocked by the damper 7, and flows into the positive ion passage 4A and the negative ion passage 4B. The air that has flowed into the positive ion passage 4A passes through the positive ion generator 6A and is added with positive ions, and then blows out from the positive ion outlet 8A. The air that has flowed into the negative ion passage 4B passes through the negative ion generator 6B and is added with negative ions, and then blows out from the negative ion outlet 8B.

The ions generated by the ion generator 6 are positive ions H ⁺ (H ₂ O) m (m is an arbitrary natural number) and negative ions O ₂ ⁻ (H ₂ O) n (n is an arbitrary natural number). The positive and negative ions are sent to the air to adhere to airborne bacteria and viruses, and the reaction that takes place generates hydroxyl radicals that are sterilized or inactivated by their activity. . Further, it has been clarified that even if the adhering substance is an odor substance or allergen in the air, it has an effect of destroying the adhering substance.

  By rotating the damper 7, the balance of the cross-sectional areas of the vent portions of the positive ion passage 4 </ b> A and the negative ion passage 4 </ b> B is changed as shown in FIGS. 3 a to i, and the fan 2 passes through the ion generator 6. Thus, it is possible to adjust the balance of each air volume sent to the positive ion outlet 8A and the negative ion outlet 8B. FIG. 4 shows changes in the cross-sectional area of the positive ion passage 4A in correspondence with a to i in FIG. Note that the vertical axis of the graph of FIG. 4 indicates that the cross-sectional area surrounded by the duct 3 is 100%. From the figure, the cross-sectional areas of the vent portions of the positive ion passage 4A and the negative ion passage 4B are equal at the positions a, e, and i, and the cross-sectional area of the vent portion of the positive ion passage 4A is maximum at the position c. (The cross-sectional area of the vent portion of the negative ion passage 4B is minimum), and the cross-sectional area of the vent portion of the positive ion passage 4A is minimum (the cross-sectional area of the vent portion of the negative ion passage 4B is maximum) at the position g. Become.

  If the amount of each ion generated in each of the positive and negative ion generators 6A and 6B is the same electrode structure, it depends on the voltage and power applied to the electrode part, but each ion transported from each ion generator 6A and 6B. Since the amount is affected by the amount of air passing through each of the ion generators 6A and 6B and the wind speed, it is possible to control the balance of positive and negative ions to be released by adjusting the balance of the amount of air flow.

  As described above, in the present invention, the amount of ventilation in each passage is adjusted by changing the cross-sectional areas of the vent portions of the positive ion passage 4A and the negative ion passage 4B. It may be a semi-circle, a circle, a rectangle or other polygons. Further, it may be a plate-like body provided with a notch at the periphery or a plate-like body provided with a vent hole. Furthermore, it is not limited to a flat plate, and a solid shape is also allowed.

  Also, the damper can be rotated to cover all the flow parts of the positive ion passage 4A and the negative ion passage 4B, and the dampers can be reduced in size so that the flow parts of the ion passages are dampers. Even when it is covered to the maximum extent, it may have a shape that reduces the decrease in cross-sectional area. FIG. 5 is a diagram for explaining the operation of the air conditioner according to the modification of the first embodiment. The damper 11 shown in FIG. 5 is a small damper having a shorter major axis and a shorter minor axis compared to the damper 7 shown in FIG. 3, and is a position eccentric from the center of the ellipse in the major axis direction. Has a rotating shaft 11A. In the case of this damper 11, the adjustment width of the cross-sectional area of the ventilation portion is reduced.

Although not shown, the control unit 12, the fan motor 13, and the damper motor 14 are installed in the housing 10.

  The controller 12 senses the ion balance in the air blown out from the positive ion outlet 8A and the negative ion outlet 8B by the ion detector 9, and when the ion balance is different from the target ion balance, By driving the damper motor 14 to rotate the rotary shaft 7A and adjusting the cross-sectional areas of the vent portions of the positive ion passage 4A and the negative ion passage 4B, the ion balance released into the air is controlled.

  The control content of the ion balance is stored in the control unit 12 as the operation mode. For example, in the “standard” mode, approximately equal amounts of positive and negative ions are released. In the “sterilization” mode, the total amount of ions is increased as compared with the “standard” mode, and almost equal amounts of positive and negative ions are transmitted. In the “deodorizing” mode, the total amount of ions is further increased compared to the “disinfecting” mode, and almost equal amounts of positive and negative ions are transmitted. In “Relax” mode, only negative ions are increased from the “Standard” mode. When adjusting the ion balance, it is possible only by controlling the rotation angle of the dampers 7 and 11 according to the above description. However, when the total ion amount is increased, the rotational speed of the fan motor 13 is increased to increase the air volume. Do by.
