  Therefore, when releasing positive ions and negative ions into the air, it is necessary to spray the positive ions and the negative ions in a state of being separated from each other. The air conditioning apparatus described in Patent Document 2 is not provided with a mechanism for separating and releasing positive ions and negative ions.

  In the air conditioner described in Patent Document 3, two discharge devices are provided in order to change the distance between the dense regions of positive ions and negative ions. Therefore, there has been a problem that the air conditioner becomes large.

Therefore, it is possible to prevent the positive ions and the negative ions from being combined and disappeared before reaching the suspended substance in the air. Moreover, the degree to which positive ions and negative ions are separated can be adjusted by adjusting the voltage applied by the voltage application device. Furthermore, since the ion dispersal device according to the present invention does not need to include a plurality of discharge devices to separate positive ions and negative ions, the device can be downsized.

  In the ion dispersal device according to the present invention, the discharge electrode may include a first ion discharge electrode that generates positive ions and a second ion discharge electrode that generates negative ions.

And a tubular second pipe having an inlet in the lee of the electrode and having an outlet in the discharge part. In the first pipe, positive ions pass through the inside, and in the second pipe, negative ions pass through the inside.

  By comprising in this way, the positive ion and negative ion which were isolate | separated by the negative electrode and the positive electrode can be separately sent to a discharge part.

In the discharge part, the outlets of the first pipe and the second pipe are mixed and arranged. By comprising in this way, the positive ion and negative ion which were separately sent to the discharge part can be disperse | distributed and scattered outside. Therefore, positive ions and negative ions can be easily combined on the suspended substance in the air.

  Preferably, in the ion dispersal device according to the present invention, the inner diameters of the first pipe and the second pipe increase in the discharge unit from the center toward the outside. By configuring in this way, the pressure difference between the center and the periphery of the discharge unit when sending ions from the discharge unit to the outside is reduced, the air flow of the scattered air is adjusted, and positive ions and negative ions are distributed. It can suppress that it couple | bonds immediately after.

  According to the present invention, the positive ions are attracted to the negative electrode, the negative ions are attracted to the positive electrode, and the positive ions and the negative ions are dispersed in a separated state before reaching the suspended matter in the air, Bonding and disappearing of positive ions and negative ions can be suppressed. Therefore, the sterilization performance of ions can be effectively exhibited.

  Hereinafter, an ion scattering apparatus according to Embodiment 1 based on the present invention will be described with reference to the drawings.

Embodiment 1
FIG. 1 is a schematic perspective view showing the structure of an ion scattering apparatus according to Embodiment 1 of the present invention. As shown in FIG. 1, in the ion scattering apparatus 1 according to Embodiment 1 of the present invention, positive ions 50 and negative ions 60 generated by applying a voltage to the discharge electrode 4 are dispersed by forced air blowing. ing.

  The ion sprayer 1 is provided with a blower 9 that sends out positive ions 50 and negative ions 60. Further, the ion dispersal device 1 is provided with a discharge electrode 4 including a first ion discharge electrode 2 that generates positive ions 50 and a second ion discharge electrode 3 that generates negative ions 60 on the lee of the blower 9. Yes.

  A voltage is applied to the first ion discharge electrode 2 and the second ion discharge electrode 3 by being connected to a power source through a wiring (not shown). A positive voltage is applied to the first ion discharge electrode 2 and a negative voltage is applied to the second ion discharge electrode 3.

  In the present embodiment, the needle electrode type discharge electrode 4 is provided, but a panel electrode type discharge electrode may be used. By applying an AC voltage to the panel electrode type discharge electrode, both positive ions and negative ions can be generated from the panel electrode.

  The ion sprayer 1 is provided with a voltage application device 8. The positive electrode 5 and the negative electrode 6 of the voltage application device 8 are arranged so as to face each other with the discharge electrode 4 interposed therebetween. The positive electrode 5 and the negative electrode 6 are connected to a DC power source 7 by wiring.

  The negative electrode 6 is provided on the side opposite to the side on which the second ion discharge electrode 3 is disposed when viewed from the first ion discharge electrode 2. The positive electrode 5 is provided on the side opposite to the side on which the first ion discharge electrode 2 is disposed when viewed from the second ion discharge electrode 3. The voltage application device 8 generates an electric field from the first ion discharge electrode 2 toward the second ion discharge electrode 3 so that the potential becomes higher.

  In the ion scattering apparatus 1 of the present embodiment, the positive ions 50 generated by the first ion discharge electrode 2 are attracted to the negative electrode 6, and the negative ions 60 generated by the second ion discharge electrode 3 are applied to the positive electrode 5. It is drawing. In this way, with the positive ions 50 and the negative ions 60 separated, the positive ions 50 and the negative ions 60 are scattered outside by the air blow by the blower 9.

  The positive ions 50 and the negative ions 60 dispersed to the outside do not immediately combine but float in the air. In the meantime, the positive ions 50 and the negative ions 60 are combined on the suspended matter, whereby the suspended matter is denatured and detoxified.

  When the voltage applied between the positive electrode 5 and the negative electrode 6 is increased by the voltage application device 8, the positive ions 50 are attracted to the vicinity of the negative electrode 6, and the negative ions 60 are attracted to the vicinity of the positive electrode 5. It is done. Therefore, the positive ions 50 and the negative ions 60 are clearly separated. In this state, when the positive ions 50 and the negative ions 60 are dispersed to the outside, it is possible to increase the time until the positive ions 50 and the negative ions 60 are combined, and to send the positive ions 50 and the negative ions 60 far away. Therefore, it is suitable for removing suspended substances in the air far from the ion dispersal device 1.

  On the other hand, when the voltage applied between the positive electrode 5 and the negative electrode 6 is reduced by the voltage application device 8, the positive ions 50 are slightly attracted to the negative electrode 6, and the negative ions 60 are slightly applied to the positive electrode 5. Be drawn to. Therefore, the positive ions 50 and the negative ions 60 are mixed at the boundary between the space where many positive ions 50 exist and the space where many negative ions 60 exist. In this state, when the positive ions 50 and the negative ions 60 are scattered outside, the positive ions 50 and the negative ions 60 are combined in a relatively short time. Therefore, it is suitable for removing suspended substances in the air in the vicinity of the ion scattering apparatus 1.

  Thus, in the ion scattering apparatus 1 of the present embodiment, the separation state of the positive ions 50 and the negative ions 60 can be adjusted by adjusting the voltage applied by the voltage application device 8. Therefore, the dispersion | spreading range of the positive ion 50 and the negative ion 60 can be changed by adjusting the time until the positive ion 50 and the negative ion 60 couple | bond.

  Further, by dispersing the positive ions 50 and the negative ions 60 in a separated state, the positive ions 50 and the negative ions 60 are restrained from being combined immediately after the dispersion, and the positive ions 50 and the negative ions 60 are suspended. The sterilization performance of ions is effectively exhibited. Furthermore, in order to separate the positive ions 50 and the negative ions 60, it is not necessary to provide a plurality of discharge devices that generate ions, so that the ion scattering device 1 can be reduced in size.

Therefore, it can suppress that the positive ion 50 and the negative ion 60 couple | bond and extinguish in the inside of the ion scattering apparatus 10. FIG. Here, it is preferable that the negative ions 60 do not pass through the positive ion induction tube 11 and the positive ions 50 do not pass through the negative ion induction tube 12, but a small amount of the negative ions 60 together with the positive ions 50 are positive ion induction. Even if it passes through the tube 11 and a small amount of positive ions 50 pass through the negative ion induction tube 12 together with the negative ions 60, the above effect can be obtained.

  Moreover, in the discharge part 13, the area | region where many positive ions 50 exist by spraying the positive ion 50 and the negative ion 60 from the exit of the positive ion induction tube 11 and the negative ion induction tube 12 which were mixed and arrange | positioned. And a region where many negative ions 60 exist can be mixed in a separated state. By spreading in this way, it is possible to facilitate the binding of the positive ions 50 and the negative ions 60 on the suspended matter in the air while suppressing the binding immediately after the scattering.

  In the present embodiment, the positive ion guide tube 11A and the negative ion guide tube 12A are arranged around the positive ion guide tube 11A and the negative ion guide tube 12A as compared with the inner diameters of the positive ion guide tube 11A and the negative ion guide tube 12A arranged in the center of the discharge unit 13.

I tried to get bigger.

  As described above, the inner diameters of the positive ion induction tube 11 and the negative ion induction tube 12 are increased from the center toward the outer side in the discharge unit 13. In the present embodiment, three types of positive ion induction tubes 11 and three types of negative ion induction tubes 12 having different inner diameters are used, but the number of induction tubes having different inner diameters is not limited thereto.

  Thus, by changing the sizes of the inner diameters of the positive ion guide tube 11 and the negative ion guide tube 12, the pressure distribution on the front surface of the discharge unit 13 when the positive ions 50 and the negative ions 60 are dispersed is made uniform. Can do. Therefore, it is possible to reduce the convection of air in the direction other than the discharge direction from the discharge unit 13 and maintain the state where the dispersed positive ions 50 and negative ions 60 are separated. Ions 60 can be sent.
