(Embodiment 1)
FIG. 1 is a perspective view of an ion generator provided with a brush-like discharge electrode as an object to be cleaned to be cleaned by the discharge electrode cleaning tool according to the present embodiment. FIG. 2 is a cross-sectional view taken along the line II-II shown in FIG. FIG. 3 is a perspective view showing a state where a lid member is removed from the ion generator shown in FIG. With reference to FIGS. 1-3, the ion generator provided with the brush-shaped discharge electrode as a to-be-cleaned object cleaned by the discharge electrode cleaning tool which concerns on this Embodiment is demonstrated.

  As shown in FIGS. 1 to 3, the ion generator includes two discharge electrodes 1 and 2, annular induction electrodes 3 and 4, and two rectangular printed boards 5 and 6. . The induction electrode 3 is an electrode for forming an electric field with the discharge electrode 1. The induction electrode 4 is an electrode for forming an electric field with the discharge electrode 2. The discharge electrode 1 is an electrode for generating negative ions with the induction electrode 3. The discharge electrode 2 is an electrode for generating positive ions with the induction electrode 4.

  The printed circuit boards 5 and 6 are arranged in parallel in the vertical direction in FIG. The induction electrode 3 is formed on the surface of one end portion in the longitudinal direction of the printed circuit board 5 by using the wiring layer of the printed circuit board 5. Inside the induction electrode 3, a hole 5a penetrating the printed circuit board 5 is opened. The induction electrode 4 is formed on the surface of the other end portion in the longitudinal direction of the printed circuit board 5 by using the wiring layer of the printed circuit board 5. Inside the induction electrode 4, a hole 5 b penetrating the printed circuit board 5 is opened. The induction electrodes 3 and 4 are formed at a low cost by the wiring layer of the printed circuit board 5, thereby reducing the manufacturing cost of the ion generator.

  Each of the discharge electrodes 1 and 2 is provided perpendicular to the printed circuit boards 5 and 6. The base end portion of the discharge electrode 1 is inserted into the hole of the printed circuit board 6, and the distal end portion passes through the center of the hole 5 a of the printed circuit board 5. The base end portion of the discharge electrode 2 is inserted into the hole of the printed circuit board 6, and the distal end portion passes through the center of the hole 5 b of the printed circuit board 5. The base ends of the discharge electrodes 1 and 2 are fixed to the printed circuit board 6 with solder.

  The induction electrodes 3 and 4 are formed on the printed circuit board 5. The discharge electrodes 1 and 2 are fixed to a printed circuit board 6 different from the printed circuit board 5. Therefore, even when the ion generator is placed in a high humidity environment with dust accumulated on the printed circuit boards 5 and 6, current leakage between the discharge electrodes 1 and 2 and the induction electrodes 3 and 4 is suppressed. It is possible to generate ions stably.

  The tip of each of the discharge electrodes 1 and 2 is formed in a brush shape. The discharge electrode 1 has a plurality of thread-like conductors 7 provided at the tip thereof, and a joint portion 7 a that bundles the roots of the plurality of conductors 7. The discharge electrode 2 has a plurality of thread-like conductors 8 provided at the tip thereof, and a joint 8 a that bundles the roots of the plurality of conductors 8. The joint portions 7a and 8a are configured by caulking metal pieces, for example.

  The conductors 7 and 8 of the discharge electrodes 1 and 2 are made of a conductive material. For example, the conductors 7 and 8 may be made of metal, carbon fiber, conductive fiber, or conductive resin. The outer diameter per conductor 7 and 8 is not less than 5 μm and not more than 30 μm. By setting the thickness of the conductors 7 and 8 to 5 μm or more, the mechanical strength of the conductors 7 and 8 is ensured, and electrical wear of the conductors 7 and 8 is suppressed. By setting the thickness of the conductors 7 and 8 to 30 μm or less, the conductors 7 and 8 that bend like hair are formed, and the conductors 7 and 8, which will be described in detail later, are likely to spread and swing. The conductors 7 and 8 may be carbon fibers having an outer diameter of 7 μm, or may be conductive fibers made of SUS having an outer diameter of 12 μm or 25 μm.

  If the lengths of the conductors 7 and 8 projecting from the joints 7a and 8a are too short, the conductors 7 and 8 are difficult to bend. The effect of the ion generator cannot be sufficiently obtained. Therefore, the length by which the conductors 7 and 8 protrude from the joint portions 7a and 8a is 3 mm or more. The conductors 7 and 8 may protrude 4.5 mm or more with respect to the joint portions 7a and 8a.

  In addition, the ion generator includes a rectangular parallelepiped casing 10 having a rectangular opening slightly larger than the printed boards 5 and 6, a lid member 11 that closes the opening of the casing 10, a circuit board 16, and a circuit. A component 17 and a transformer 18 are provided.

  The printed boards 5 and 6 are accommodated horizontally in the upper part of the housing 10.

The high voltage part in the housing 10 is filled with an insulating material 19 such as resin. The insulating material 19 is filled up to the lower surface of the printed circuit board 6. In the present embodiment, the circuit component 17 disposed in the space defined by the partition plate 10a and the circuit board 16 provided in the lower part of the housing 10 does not need to be insulated by the insulating material 19, so that the partition The space on the other side of the plate 10a is not filled with the insulating material 19.

  The lid member 11 is made of an insulating resin. Grooves are formed in the upper end portion of the inner wall of the housing 10, and locking portions that are inserted into the grooves of the housing 10 protrude from both ends in the longitudinal direction of the lid member 11. Since the printed circuit boards 5 and 6 are covered with the lid member 11, dust accumulation on the printed circuit boards 5 and 6 is suppressed.

  A hollow cylindrical boss 11 a is formed on the lower surface of the lid member 11 at a position corresponding to the hole 5 a and the discharge electrode 1. On the lower surface of the lid member 11, a hollow cylindrical boss 11 b is formed at a position corresponding to the hole 5 b and the discharge electrode 2. The bosses 11a and 11b are formed to extend in the thickness direction of the printed boards 5 and 6. The inner diameters of the bosses 11a and 11b are larger than the outer diameters of the discharge electrodes 1 and 2, respectively. The lid member 11 is formed with a hole penetrating the lid member 11 in the thickness direction inside the bosses 11a and 11b. The discharge electrodes 1 and 2 penetrate the bosses 11a and 11b, respectively. The discharge electrodes 1 and 2 project from the lid member 11 through holes formed in the lid member 11. The conductors 7 and 8 at the distal ends of the discharge electrodes 1 and 2 protrude on the lid member 11, so that even when dust accumulates on the lid member 11, the conductors 7 and 8 are buried in the dust and discharged. Will not be disturbed.

  The outer diameters of the bosses 11a and 11b are smaller than the inner diameters of the holes 5a and 5b of the printed circuit board 5, respectively. Boss 11a, 11b has penetrated holes 5a, 5b of printed circuit board 5, respectively. A slight gap is formed between the front end surfaces (lower end surfaces) of the bosses 11 a and 11 b and the surface of the printed circuit board 6. By providing the bosses 11a and 11b, the spatial distance between the discharge electrodes 1 and 2 and the induction electrodes 3 and 4 is increased, and the current between the discharge electrodes 1 and 2 and the induction electrodes 3 and 4 is increased. Leakage can be suppressed more effectively.

  A high voltage is applied to the discharge electrode 1 and the discharge electrode 2 from a high voltage circuit including the circuit board 16, the circuit component 17, and the transformer 18. A positive high voltage pulse is applied to the discharge electrode 1, and a negative high voltage pulse is applied to the discharge electrode 2. Thereby, corona discharge is generated in the conductors 7 and 8 at the tips of the discharge electrodes 1 and 2 to generate positive ions and negative ions, respectively.

The positive ion is a cluster ion in which a plurality of water molecules are clustered around a hydrogen ion (H ⁺ ), and is represented as H ⁺ (H ₂ O) _m (m is an arbitrary integer of 0 or more). A negative ion is a cluster ion in which a plurality of water molecules are clustered around an oxygen ion (O ₂ ⁻ ), and is represented as O ₂ ⁻ (H ₂ O) _n (n is an arbitrary integer of 0 or more). 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.
