Description

  The present invention relates to an ion generator and an electric device using the same, and more particularly to an ion generator that generates positive ions and negative ions and an electric device using the same.

  In recent years, ion generators that generate both positive ions and negative ions have been put into practical use.

  An ion generating element 2 and an ion generating element 3 are disposed at the upper end portion that appears in the plan view of the ion generating apparatus 500. Each of the ion generating element 2 and the ion generating element 3 has a needle electrode and an induction electrode arranged so as to surround the needle electrode, and when a positive high voltage pulse or a negative high voltage pulse is applied between the needle electrode and the ion generating element 3 Corona discharge is generated at the tip of the needle electrode, and positive ions or negative ions are generated at the tip of the needle electrode. In the figure, the ion generating element 2 generates positive ions, and the ion generating element 3 generates negative ions.

  The generated positive ions and negative ions are sent into the room by blowing air from a blower or the like, surrounds mold fungi and viruses floating in the air, and decomposes the fungi and viruses (for example, refer to Patent Documents 1 to 3). .

  FIG. 15 is a cross-sectional view showing the internal structure of the ion generator 500 in the cross section taken along line XV-XV in FIG. The substrate S1 on which the needle electrode and the induction electrode are installed, and the circuit substrate S2 to which the step-up transformer 31 is attached and the transformer drive circuit and the like are incorporated are integrated into the housing 501 by filling the urethane resin U1 and the epoxy resin E1. Fixed.

  The ion generator 500 having the above-described configuration includes an ion generator, an air purifier, an air conditioner (air conditioner), a refrigeration apparatus, a vacuum cleaner, a humidifier, a dehumidifier, whose main purpose is to release ions into the room.

  However, when the ion generator 500 is used, there are the following problems. Referring to the internal structure of the housing 501 shown in FIG. 15, the step-up transformer 31 is disposed below the ion generating element 3 that generates negative ions.

  In this case, in order to optimize the ion generation amount, when the ion generators 500 are arranged as shown in FIG. 13 (upper +-+, lower-++), the ion generating elements 3 are arranged. The step-up transformer 31 is placed adjacent to the place (-in the upper stage). If the step-up transformer 31 is disposed adjacent to each other, there is a concern that the high-voltage output voltage may be reduced due to the influence of each other's magnetic field.

  Further, when referring to one ion generating device 500, the ion generating element 2 and the ion generating element 3 are arranged at both side ends of the housing 501 (for example, P2 = about 38 mm, P3 = about 10 mm). Therefore, when the ion generators 500 are arranged as shown in FIG. 13, the arrangement is such that the ion generating elements are concentrated in the center. Further, when the arrangement intervals of the ion generating elements are made uniform, it is necessary to arrange the ion generating devices 500 apart from each other, and there is a problem that the ion generating device 500 cannot be installed at a desired position in a small electric device. is there.

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 ion generator 100 according to the present embodiment, a transformer drive circuit is connected to the primary winding of the step-up transformer, and an ion generating element that generates positive ions and negative ions are generated in the secondary winding of the step-up transformer. A configuration in which two or more sets of ion generating elements are connected to each other is adopted.

  More specifically, in the transformer drive circuit C1, the secondary winding 131b of the step-up transformer 131 includes a set of an ion generating element 11 that generates positive ions and an ion generating element 13 that generates negative ions, and positive ions. Two sets of ion generating elements, ie, an ion generating element 12 that generates ions and an ion generating element 14 that generates negative ions, are connected.

  Also in the transformer drive circuit C2, the secondary winding 231b of the step-up transformer 231 includes a set of an ion generating element 23 that generates positive ions and an ion generating element 21 that generates negative ions, and ions that generate positive ions. Two sets of ion generating elements, that is, a generating element 24 and a set of ion generating elements 22 that generate negative ions, are connected.

  Thereby, eight ion generating elements (a total of four sets of ion generating elements) can be arranged at a predetermined interval at a desired position as shown in FIG. In addition, since one step-up transformer is used for four ion generating elements, it is possible to relax restrictions on the position of the step-up transformer. In addition, it is possible to reduce circuit parts including reduction of electric wires, halving of power consumption, and halving of the step-up transformer, and it is possible to reduce the cost required for manufacturing the ion generator.

  As shown in FIG. 3, the first transformer driving circuit C1 and the second transformer driving circuit C2 are incorporated in one circuit board S2, and the second step-up transformer 131 used for the transformer driving circuit C1 and the transformer driving circuit C2 are used. It is possible to adopt a configuration in which the second step-up transformer 231 used in the circuit board S2 is disposed at both ends on the back side of the base 10 with the circuit board S2 interposed therebetween, and the influence of the magnetic field between the step-up transformers can be eliminated. It becomes possible.

  Further, in the configuration of the ion generator 100, a space is formed between the outer edge of the base 10 and the step-up transformer (gap T in FIG. 4 and gap U in FIG. 5) from the outer edge of the base 10. Also, a step-up transformer can be arranged inside. As a result, even when a plurality of ion generators 100 are arranged side by side, the influence of the magnetic field between adjacent step-up transformers can be eliminated.

  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. The case where the ion generating elements are provided and two sets of ion generating elements are provided in the transformer driving circuit C2 has been described. However, the present invention is not limited to this circuit configuration, and a configuration in which more sets of ion generating elements are provided is adopted. It is also possible.

  Moreover, as shown in FIG. 7, it is also possible to employ | adopt the structure of the ion generator which has only two sets of ion generating elements by the transformer drive circuit C1.

  In the circuits shown in FIGS. 6 and 7, 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, the transformer is similarly connected to the primary winding of the step-up transformer. A configuration in which a drive circuit is connected and two or more sets of ion generating elements are connected to a secondary winding of a step-up transformer, with an ion generating element generating positive ions and an ion generating element generating negative ions as a set Can be adopted.

(Embodiment 2)
With reference to FIG. 8 to FIG. 12, the ion generator 2000 equipped with the ion generator 100 shown in the first embodiment will be described. This ion generator 2000 includes two sets of sirocco fans 34, and includes a lower case 31 having air intakes 35 on both sides and an upper case 32 having two air outlets 33 on the upper side. . 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.

  With reference to FIG. 11, the wind speed blown to the sirocco fan 34 and the arrangement positions of the ion generating elements 11 to 14 and 21 to 24 will be described. As shown in FIG. 11, the wind speed blown from the sirocco fan 34 has a maximum wind speed of 10 m / s at the center, and the wind speed decreases on both the left and right sides.

  Therefore, in this ion generating apparatus 100, the ion generating elements 11 to 14, 21 to 24 are arranged at a position where the maximum wind speed from the sirocco fan 34 is 10 m / s. Thereby, the ions generated by the ion generating elements 11 to 14 and 21 to 24 are carried on the wind with the maximum wind speed of 10 m / s, and the amount of ions to be introduced into the room can be increased.

  Here, FIG. 12 illustrates a case where four ion generators 500 shown in the background art are arranged. In the ion generating apparatus 500, the arrangement pitch between the ion generating element 2 and the ion generating element 3 is fixed in advance (about 38 mm). Therefore, when mounted on the ion generator 2000, the arrangement positions of the ion generation element 2 and the ion generation element 3 are shifted from the position of the maximum wind speed from the sirocco fan 34 of 10 m / s. As a result, ions generated by the ion generating elements 2 and 3 cannot be sufficiently carried out into the room.

  Thus, in the ion generator 2000 equipped with the ion generator 100 according to the present invention, the ions generated in the ion generator 100 can be efficiently sent into the room, so that the same ion delivery amount can be obtained. For example, the rotational speed of the sirocco fan 34 can be reduced as compared with the case where the ion generator 500 shown in the background art is used.

  Thereby, the value of the rotational sound of the sirocco fan 34 can be reduced. Further, if the number of rotations is the same, in the ion generator 2000 equipped with the ion generator 100, the concentration of the transmitted ions can be increased.

  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). It can be installed in refrigeration equipment, vacuum cleaners, humidifiers, dehumidifiers, drying washing machines, washing machines, electric fan heaters, microwave ovens, etc., and has a blower for sending ions in an air stream. It can be mounted on any electrical device.

  Although the embodiments of the present invention have been described above, the embodiments disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
