Since the air supply unit 1b applied to the first floor and the air supply unit 1a applied to the second floor are configured in substantially the same manner, only the air supply unit 1a applied to the second floor will be described below. A description of the air supply unit 1b applied to the first floor is omitted.

  FIG. 2 is a view of the air supply port 2a shown in FIG. In FIG. 2, 11a, 11b, 11c, and 11d are LED lamps. FIG. 3 is an enlarged cross-sectional view of the air supply port 2a and the like shown in FIG. In FIG. 3, reference numeral 30 denotes an ion generating element that generates ions for cleaning the air supplied into the room through the air supply port 2a, specifically, a cluster ion generating element. Reference numeral 31 denotes a fan for supplying the ions generated by the ion generating element 30 together with air into the room, and reference numeral 32 denotes a filter.

  4 is an enlarged perspective view of the ion generating element 30 shown in FIG. 3, and FIG. 5 is an enlarged cross-sectional view of the ion generating element 30 shown in FIG. 4 and 5, 40 is a dielectric substrate, 41 is a lower plate constituting a part of the dielectric substrate 40, and 42 is an upper plate constituting a part of the dielectric substrate 40. Reference numeral 43 is a discharge electrode, 44 is a dielectric electrode, 45 is a protective layer, and 46 and 47 are electrode contacts.

  As shown in FIGS. 4 and 5, in the ion generating element 30 of the air supply unit 1a of the first embodiment, the lower plate 41 and the upper plate 42 stacked in the thickness direction are integrated to form a dielectric material. A substrate 40 is formed. A grid-like discharge electrode 43 is formed on the upper surface of the dielectric substrate 40. A planar dielectric electrode 44 is embedded between the lower plate 41 and the upper plate 42 so as to face the discharge electrode 43. The upper side of the discharge electrode 43 is covered with a protective layer 45.

  For the lower plate 41 and the upper plate 42 constituting the dielectric substrate 40, a resin material such as polyimide and epoxy, or a ceramic material such as alumina, crystallized glass, forsterite and steatite can be used together with the protective layer 45. However, it is desirable to use a ceramic material superior in heat resistance and strength, particularly alumina.

  The discharge electrode 43 and the induction electrode 44 can be formed of a metal material usually used for electrode formation. However, when the dielectric substrate 40 and the protective layer 45 are made of a ceramic material, they can withstand these firing temperatures. In addition, it is desirable to use a metal material having a high melting point such as tungsten or molybdenum.

  In the ion generating element 30 of the air supply unit 1a of the first embodiment, for example, the induction electrode 44 is formed on the surface of the lower plate 41 made of an alumina sheet by pattern printing of a tungsten material. An upper plate 42 made of an alumina sheet is placed and crimped so as to cover it. Next, a discharge electrode 43 is formed on the surface of the upper plate 42 by pattern printing of a tungsten material. Furthermore, the protective layer 45 made of alumina is formed by coating so as to cover the entire formation region of the discharge electrode 43, and finally, these are fired in a non-oxidizing atmosphere of 1400 to 1600 ° C.

  The discharge electrode 43 is connected to the back surface of the dielectric substrate 40 by an electrode contact 46 that penetrates the upper plate 42 and the lower plate 41. The induction electrode 44 is communicated with the back surface of the dielectric substrate 40 by an electrode contact 47 penetrating the lower plate 41. A high-voltage AC drive voltage is applied between the discharge electrode 43 and the induction electrode 44 via electrode contacts 46 and 47. The electrode contacts 46 and 47 can be formed integrally by filling the through holes formed at the corresponding positions with an electrode material in the process of forming the electrodes 43 and 44, respectively.

  The reason why the discharge electrode 43 is formed in a grid is to increase the amount of ions generated with the application of the drive voltage as much as possible. In addition, the induction electrode 44 is formed so as to be centered with respect to the discharge electrode 43, and is formed in a strip shape whose length and width are smaller than that of the discharge electrode 43. This shape also contributes to an increase in the amount of ions.

  In the ion generating element 30 of the air supply unit 1a of the first embodiment, for example, a lower plate 41 and an upper plate 42, each having a thickness of about 0.45 mm, are overlapped, and the size is about 15 mm × 37 mm × 0. A 9 mm dielectric substrate 40 is formed. On the surface of the dielectric substrate 40, grid-like discharge electrodes 43 having a line width of 0.25 mm, a pitch of 0.8 mm, and a size of about 10.4 mm × 28 mm are formed. On the other hand, a planar induction electrode 44 having a size of about 6 mm × 24 mm is formed between the lower plate 41 and the upper plate 42. A high-voltage AC drive voltage having a voltage of approximately 4.6 kV (peak value) and a frequency of 22 kHz is applied between the discharge electrode 43 and the dielectric electrode 44. Due to the action of plasma discharge generated between the discharge electrode 43 and the dielectric electrode 44, positive ions and negative ions exceeding 200,000 ions / cc are generated at positions 25 cm away from the ion generating element 30, respectively. This amount of ion generation is sufficient to function as an air cleaning device for a room having a general size.

  The ion generation amount can be increased by increasing the size of the ion generation element 30 and can also be increased by increasing the drive voltage. However, when the drive voltage is increased, the amount of ozone generated is increased, so it is not desirable to increase the drive voltage excessively.

  Further, the shapes of the discharge electrode 43 and the induction electrode 44 and the size and thickness of the dielectric (upper plate 42) interposed therebetween can be changed as appropriate. Further, the ion generating element 30 may have a configuration other than the above-described configuration as long as it includes a discharge electrode and an induction electrode that are opposed to each other with a plate-like dielectric therebetween and has a flat plate shape as a whole.

  In the air supply unit 1a of the first embodiment, as shown in FIG. 3, the ion generating element 30 is arranged so as to face the flow of air supplied into the room by the fan 31. Therefore, water vapor in the air supplied into the room is ionized by plasma discharge, and approximately the same amount of positive ions and negative ions are generated and released into the room through the air inlet 2a.

Specifically, a positive ion is a cluster ion in which a plurality of water molecules are attached around a hydrogen ion (H ⁺ ), and is expressed as H ⁺ (H ₂ O) _m (m is a natural number). Negative ions are cluster ions in which a plurality of water molecules are attached around oxygen ions (O ₂ ⁻ ), and are expressed as O ₂ ⁻ (H ₂ O) _n (n is a natural number). These positive ions and negative ions are released into the room through the air inlet 2a, and then aggregate into floating substances (particles, bacteria) in the room and chemically react with each other to produce hydrogen peroxide H as an active substance. _It becomes ₂ O ₂ or hydroxyl radical / OH, inactivates suspended particles by oxidation reaction, and sterilizes suspended bacteria. Thereby, the air in the room where the air supply unit 1a is arranged is cleaned. The air supply unit that directly introduces outside air sterilizes the floating bacteria contained in the outside air, supplies the outside air to the room, and sterilizes the floating bacteria contained in the room, thereby purifying the room air.

  Furthermore, in the air supply unit 1a of the first embodiment, as shown in FIGS. 6 and 7, a power storage device 51 including a double layer capacitor for storing the power generated by the solar power generator 3a is provided. ing. Specifically, in the daytime, the electric power generated by the solar power generator 3a is stored in the power storage device 51, and at night when the solar power generator 3a cannot supply power to the ion generating element 30, ions from the power storage device 51 are stored. Electric power is supplied to the generating element 30. Therefore, even at night when power cannot be supplied from the solar power generator 3a to the ion generating element 30, it is possible to supply power to the ion generating element 30 and generate ions.
