  • Patent number: 7961451
    Abstract: An ion generating element includes a positive ion discharger for generating positive ions and a negative ion discharger for generating negative ions. The ion dischargers are arranged separately from and independently of each other with a distance securing insulation between them. At least one of the dischargers includes a discharging portion for causing electric discharge, and a conducting portion having a voltage same as the discharging portion. The conducting portion surrounds a perimeter or part of the discharging portion. The conducting portion may surround a perimeter or part of the discharging portion so as to partition the ion dischargers from each other.

  • Publication number: 20110102963
    Abstract: An ion-generating device has a positive electrode pair and a negative electrode pair. The positive electrode pair and the negative electrode pair are disposed in a casing with a space interposed therebetween, such that an induction electrode in the positive electrode pair and an induction electrode in the negative electrode pair are separated from each other. It is thereby possible to obtain an ion-generating device and an electrical apparatus, capable of efficiently emitting both of positive ions and negative ions to an outside of the device, and easily achieving reduction in size and thickness.

  • Patent number: 7854900
    Abstract: An ion generating device generates O2?(H2O)n (where n is a natural number) as negative ions and H+(H2O)m (where m is a natural number) as positive ions, and discharges those ions into the air so that airborne germs are killed through an oxidation reaction by hydrogen peroxide H2O2 or radical hydroxyl OH generated through as an active species a chemical reaction between the negative and positive ions. Satisfactory sterilization is achieved when the negative and positive ions are generated in such a way that the concentrations of the negative and positive ions are both 10,000 ion/cc at a distance of 10 cm from the point at which they are generated.

  • Patent number: 7639472
    Abstract: An ion generating element (10) has at least one first discharger (12) for generating positive ions and at least one second discharger (13) for generating negative ions, both fitted or printed on a single dielectric member (11). The first and second dischargers (12) and (13) are each composed of a pair of a first or second discharging electrode (12a) or (13a), respectively, formed on the surface of the dielectric member (11) and a first or second induction electrode (12b) or (13b), respectively, buried in the dielectric member (11), and are arranged both on the same flat surface of the dielectric member (11) but separately from and independently of each other. This construction helps to alleviate the neutralization among the generated ions themselves, thus to effectively release both positive and negative ions, and thereby to enhance the ion generation efficiency.

  • Publication number: 20090140164
    Abstract: An ion generation element includes an induction electrode and a plurality of discharge electrodes. The induction electrode is formed of one metal plate. A circumferential portion of a through hole is bent, and a thickness of a wall portion of the through hole is greater than a thickness of a top plate portion . A needle-like tip end of the discharge electrode is located within a range of the thickness of the through hole. Thus, an induction electrode having a structure realizing a small thickness, capable of lessening variation in an amount of ion generation caused by variation in positional relation between the tip end of the discharge electrode and the induction electrode, an ion generation element, an ion generation apparatus, and electric equipment can be obtained.

  • Patent number: 7312973
    Abstract: An air conditioning apparatus incorporates an ion generating device that generates positive and negative ions by applying an alternating-current voltage between electrodes. The generated positive and negative ions coexist in the air and, when they attach to the surfaces of airborne bacteria, they react chemically with each other and generate radical hydroxyl and hydrogen peroxide, which extract hydrogen atoms from the cells of the bacteria and thereby kill them. This sterilizing effect is combined with the temperature-conditioning, dehumidifying, humidifying, air-purifying, and other functions of the air conditioning apparatus to bring about a comfortable and healthful indoor environment.

  • Patent number: 7256979
    Abstract: A booster coil is stored in a coil storing room provided in the bottom section of a common case having an opening on one side, and is insulation-molded with a filler. A circuit substrate is inserted into the common case and supported by a supporting edge which is provided circumferentially at the middle of an inner wall of the common case. An ion generating element is held on a lid plate for closing the opening of the common case and mounted on the outer surface of the common case together with this lid plate, and the space between the circuit plate and the ion generating element is insulation-molded with a filler. An ion generator including the ion generating element and the booster coil and circuit substrate for generating a driving voltage is constructed in a compact size so as to enable the ion generator to be readily used in a wide range of applications.

  • Patent number: 7254006
    Abstract: An inner electrode formed inside a dielectric body and a surface electrode formed on a surface of the dielectric body. The surface electrode is formed in a grid pattern with pointed parts formed inside the grid section. Each pointed part is in the shape of a triangle whose vertices are two arbitrary points on a side of the grid section and an arbitrary point inside the grid section, or a quadrangle whose vertices are a crossing of grid lines, an arbitrary point near a straight line connecting crossings of grid lines in the diagonal positions, and two arbitrary points on sides of the grid section. An ion generating element is formed which can generate positive ions and negative ions. The ion generator can be used in an air conditioning apparatus, cleaner or refrigerator.

  • Patent number: 7120006
    Abstract: A switching transformer applies an alternating high voltage across an internal electrode and an external electrode which face each other with a glass tube as a dielectric body between them. The anode side of a diode is connected to the external electrode which is not a voltage supply side electrode, while the cathode side is grounded. When a relay connected to both the terminals of the diode is turned on, substantially equal amounts of positive ions and negative ions are generated, and a bacteria removal/disinfection effect can be obtained by emitting these positive ions and negative ions into the air. When the relay is turned off, a relatively small amount of positive ions and a relatively large amount of negative ions are generated, and a relaxation effect given by negative ions can be obtained by emitting these positive ions and negative ions into the air.
