Two sets of ion generating elements are connected to the set of ion generating elements 22 that generate negative ions.

(Operation of the ion generator 100)
Next, the operation of the ion generator 100 will be described. Since the operations of the transformer drive circuit C1 and the transformer drive circuit C2 are the same, only the transformer drive circuit C1 will be described here.

  The capacitors 129b and 129c are charged by the RCC switching power supply operation. That is, when a DC power supply voltage is applied between the power supply terminal T11 and the ground terminal T12, a current flows from the power supply terminal T11 to the base of the transistor 126 through the diode 120 and the resistance elements 121 and 123, and the transistor 126 becomes conductive. Become. As a result, a current flows through the primary winding 127a of the first step-up transformer 127, and a voltage is generated between the terminals of the base winding 127b.

  The winding direction of the base winding 127b is set so that the base voltage of the transistor 126 is further increased when the transistor 126 becomes conductive. For this reason, the voltage generated between the terminals of the base winding 127b reduces the conduction resistance value of the transistor 126 in a positive feedback state. At this time, the winding direction of the secondary winding 127c is set so that energization is blocked by the diode 128, and no current flows through the secondary winding 127c.

  As the current flowing through the primary winding 127a and the transistor 126 continues to increase in this manner, the collector voltage of the transistor 126 rises out of the saturation region. As a result, the voltage between the terminals of the primary winding 127a decreases, the voltage between the terminals of the base winding 127b also decreases, and the collector voltage of the transistor 126 further increases.

  Therefore, the transistor 126 operates rapidly in the positive feedback state, and the transistor 126 is rapidly turned off. At this time, the secondary winding 127 c generates a voltage in the conduction direction of the diode 128. Thereby, the capacitors 129b and 129c are charged.

  When the voltage between the terminals of the capacitors 129b and 129c rises and reaches the breakover voltage of the two-terminal thyristor 130, the two-terminal thyristor 130 operates like a Zener diode and further flows current. When the current flowing through the two-terminal thyristor 130 reaches the breakover current, the two-terminal thyristor 130 is substantially short-circuited, and the charge charged in the capacitor 129 passes through the two-terminal thyristor 130 and the primary winding 131a of the second step-up transformer 131. And an impulse voltage is generated in the primary winding 131a.

  When an impulse voltage is generated in the primary winding 131a, positive and negative high voltage pulses are generated in the secondary winding 131b while being attenuated alternately. A positive high voltage pulse is applied to the needle electrodes 101 and 102 via the diode 106, and a negative high voltage pulse is applied to the needle electrodes 103 and 104 via the diode 107. Thereby, corona discharge is generated at the tips of the needle electrodes 101 to 104, and positive ions and negative ions are generated, respectively.

  On the other hand, when a current flows through the secondary winding 127c of the first step-up transformer 127, the voltage between the terminals of the primary winding 127a increases and the transistor 126 is turned on again, and the above operation is repeated. The repetition rate of this operation increases as the current flowing through the base of the transistor 126 increases. Therefore, by adjusting the resistance value of the resistance element 121, the current flowing through the base of the transistor 126 can be adjusted, and thus the number of discharges of the needle electrodes 101 to 104 can be adjusted.

A positive ion is a cluster ion in which a plurality of water molecules are attached around a hydrogen ion (H ⁺ ), and is represented as H ⁺ (H ₂ O) m (where m is an arbitrary natural number). The negative ion is a cluster ion in which a plurality of water molecules are attached around an oxygen ion (O ₂ ⁻ ), and is represented as O ₂ ⁻ (H ₂ O) n (where n is an arbitrary natural number). .

  Moreover, when positive ions and negative ions are released into the room, both ions surround mold fungi and viruses floating in the air and cause a chemical reaction with each other on the surface. Suspended fungi and the like are removed by the action of the active species hydroxyl radical (.OH) generated at that time.

(Action / Effect)
As described above, in the ion generator 100 according to the present embodiment, in the transformer drive circuit C1, the connection between the one terminal of the primary winding 131a of the second step-up transformer 131 and the two-terminal thyristor 130, and the second step-up transformer 131 A transformer connector C100 is used to connect the other terminal of the primary winding 131a and the ground terminal T12.

  Similarly, in the transformer drive circuit C2, the connection between one terminal of the primary winding 231a of the second boost transformer 231 and the two-terminal thyristor 230, and the other terminal of the primary winding 231a of the second boost transformer 231 and the ground terminal T22. The transformer connector C200 is used for the connection.

  Thereby, when the ion generating elements 11 to 14 and the ion generating elements 21 to 24 reach the end of their lives and the ion generating device 100 is recovered, the transformer driving circuit C1 and the transformer driving circuit C2 are transferred by the transformer connector C100 and the transformer connector C200. After the circuit board S2 in which is incorporated is removed from the base 10, the circuit board S2 can be mounted on the base 10 having the new ion generating elements 11-14 and the ion generating elements 21-24.

  As a result, the circuit board S2 in which the transformer drive circuit C1 and the transformer drive circuit C2 that have not been reused in the past can be easily reused, and the circuit board S2 can be reused according to the life of the component parts. It is possible to provide an ion generating apparatus that can be used and can take into consideration the global environment.

  Further, the circuit board S2 side in which the transformer driving circuit C1 and the transformer driving circuit C2 are incorporated is incorporated in the external device side, and only the base 10 side having the ion generating elements 11-14 and 21-24 and the second step-up transformers 131 and 231 is incorporated. It is also possible to adopt a configuration that enables replacement.

  As shown in FIGS. 6 and 7, by extending the cable 131C connected to the second step-up transformer 131 and the cable 231C connected to the second step-up transformer 231 from the beginning, the transformer drive circuit C1 and It is also possible to arrange the circuit board S2 in which the transformer drive circuit C2 is incorporated at a position different from the base 10.

  As a comparative example, FIGS. 8 and 9 illustrate cases where transformer connectors C100 and C200 are used to connect the secondary winding side terminals of the second step-up transformers 131 and 231 and the ion generating element, respectively. When the transformer connectors C100 and C200 are used to connect the secondary winding side terminals of the second step-up transformers 131 and 231 and the ion generating element, respectively, the second step-up transformers 131 and 231 are incorporated in the circuit board S2. The second step-up transformers 131 and 231 can be reused.

  However, the withstand voltage of the connecting wires requires AC 5 kV to AC 10 kV, which increases the size and cost of the wires and connectors in order to increase the insulation performance of the wires and connectors. In addition, the ion generator itself is increased in size. Therefore, as shown in the above embodiment, it is preferable that the transformer driving circuit and the primary winding side of the step-up transformer are detachably connected by a transformer connector as a connecting member.

  In the above embodiment, when four ion generating elements are provided with one set of an ion generating element that generates positive ions and one that generates negative ions, two sets of transformer generating circuits C1 are provided in the transformer driving circuit C1. Although the case where two sets of ion generating elements are provided in the ion generating element / transformer driving circuit C2 has been described, the present invention is not limited to this circuit configuration.

  For example, as shown in FIG. 10, an ion generator having only two sets of ion generating elements by a transformer driving circuit C1, and as shown in FIG. 11, an ion generation having only one set of ion generating elements by a transformer driving circuit C1. In the apparatus, it is also possible to adopt a configuration in which the transformer drive circuit and the primary winding side of the step-up transformer are detachably connected by a transformer connector C100 as a connecting member.

  5, 10, and 11, the case where a DC power source is used as the power source has been described. However, even when an AC power source is used as the power source, two boost transformers are similarly used. It is possible to adopt a configuration in which an ion generating element is connected to the secondary winding side, and the transformer driving circuit and the primary winding side of the step-up transformer are detachably connected by a transformer connector as a connecting member.

Inside the lower case 31 and the upper case 32, a wind tunnel 36 for guiding the air flow blown from the sirocco fan 34 toward the blowout port 33 is formed.

  The ion generator 100 is accommodated in the cases 1001 and 1002 shown in FIG. The ion emission holes h11 to h14 and h21 to h24 face the wind tunnel 36 and are arranged so that ions generated by the ion generation elements 11 to 14 and 21 to 24 can be released to the air flow.

  According to this ion generator 2000, it is possible to release air containing ions from the outlet 33 by allowing the ion generating device 100 to pass the air.

  In addition, the ion generator shown in Embodiment 1 is not only an electric device whose main purpose is to release ions like the above-described ion generator 2000 into the room, but also an air purifier and an air conditioner (air conditioner).
