  As shown in FIG. 9, the ion generator 40 is packaged with a discharge electrode 43 (43 </ b> P, 43 </ b> N) used for discharge for discharging ions and other electronic components (not shown) provided in a housing 41. The ion generator 40 includes a discharge circuit unit (not shown), a positive ion generation unit 42P, and a negative ion generation unit 42N. The discharge circuit unit includes a high-voltage electricity generation circuit that generates a high-voltage electric pulse upon receiving external power supply.

  The positive ion generating part 42P and the negative ion generating part 42N are arranged side by side at a predetermined interval, and each protrudes from the outer surface of the ion generating device 30 toward the air circulation space of the air duct 6. The positive ion generating part 42P and the negative ion generating part 42N are arranged in a direction that intersects the air circulation direction of the air circulation space and forms a substantially right angle.

A positive voltage is applied to the positive discharge electrode 43P, and hydrogen ions generated by corona discharge combine with moisture in the air to generate positive ions mainly composed of H ⁺ (H ₂ O) m. A negative voltage is applied to the negative discharge electrode 43N, and oxygen ions generated by corona discharge combine with moisture in the air to generate negative ions mainly composed of O ₂ ⁻ (H ₂ O) n. Here, m and n are arbitrary natural numbers. H ⁺ (H ₂ O) m and O ₂ ⁻ (H ₂ O) n aggregate on the surface of airborne bacteria and odorous components and surround them.

→ 2 OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)

  Note that positive ions and negative ions may be generated together by the ion generator 40, or only positive ions or only negative ions may be generated.

  In the present invention, the ion includes charged fine particle water. At this time, the ion generator 40 includes an electrostatic atomizer, and charged fine particle water containing a radical component is generated by the electrostatic atomizer. That is, condensation water is generated on the surface of the discharge electrode by cooling the discharge electrode provided in the electrostatic atomizer by the Peltier element. Next, when a negative high voltage is applied to the discharge electrode, charged fine particle water is generated from the dew condensation water. Further, negative ions released into the air together with the charged fine particle water are also generated from the discharge electrode.

  The ion generator 40 may be composed of an electrostatic atomizer that generates either positive ions or negative ions and fine particle water charged to a polarity opposite to that of the positive ions or negative ions. When negative ion or negatively charged fine particle water is generated, it is said that in addition to sterilization and deodorization in the room, a relaxing effect is also produced.

  Here, the ion generator 1 is provided with the time measuring part 18, the illumination intensity measurement part 19, and the human sensitive sensor 20 as shown in FIG.

Determine whether there are people in the room.

  And the ion generator 1 makes the ventilation fan 7 operate | move in a mode more rapid than usual at night or when there is no person in the room, and increases the ion concentration in the room. When the blower fan 7 is operated in the rapid mode, the power consumption is high and the noise increases, but the adverse effect is small when there are no people at night or indoors. By operating the blower fan 7 in the rapid mode at night or when there is no person in the room, the effect of sterilization and deodorization in the room is improved.

  As shown in FIG. 9, the ion sensor 50 includes a collecting electrode 51 that is exposed to the outside of the ion generator 30 and toward the air circulation space of the air duct 6. The ion sensor 50 detects the electric charge per unit time which is generated when the ions touch the collecting electrode 51 as a current. And the voltage corresponding to the ion amount collected by satisfy | filling the capacity | capacitance of the integrator provided in the circuit part not shown is obtained. The amount of ions can be measured by checking this voltage after a predetermined time since the collection electrode 51 is reset.

  Here, the ion generator 30 is arranged facing the air circulation space formed by using the internal heat insulating material 17 partially made of foamed polystyrene or the like. It has been found that expanded polystyrene is generally easily charged positively, and negative ions are likely to adhere to the air circulation space made of expanded polystyrene. For this reason, the ion sensor 50 is arrange | positioned in the air distribution direction downstream of the positive ion generation part 42P.

  The rib part 60 is arrange | positioned in the location corresponding to the outer periphery of the ion generator 30 as shown in FIG. 9, and the circumference | surroundings of the ion sensor 50 located in the air flow direction downstream of the positive ion generation part 42P. The rib part 60 protrudes from the outer surface of the ion generator 30 toward the air circulation space. The rib portion 60 improves the efficiency related to the inflow of positive ions emitted from the positive ion generating portion 42P into the ion sensor 50, and prevents the inflow of negative ions emitted from the negative ion generating portion 12N into the ion sensor 50. With ribs.

  As shown in FIG. 9, the light emitting unit 70 is disposed on the outer surface of the ion generating device 30 and downstream of the negative ion generating unit 42N in the air flow direction. The light emitting unit 70 includes a light source substrate 71 on which, for example, LEDs are mounted as light emitters, and a diffusion lens 72 for diffusing the LED light to the air circulation space side. The light emitting unit 70 emits light so that it can be easily recognized from the outside that the ion generator 40 is operating normally.

  Here, the ion generator 1 turns off the light emitting unit 70 at night using the time measuring unit 18 and the illuminance measuring unit 19. Thereby, power consumption can be reduced. Further, by turning off the light emitting unit 70 at night, for example, if the light emitting unit 70 is blinking due to an abnormality of the ion generator 40, it becomes easy to notice it. Therefore, it is possible to quickly cope with the abnormality of the ion generator 1.

  Subsequently, a more detailed configuration around the partition 16 will be described.

  As shown in FIGS. 2 and 6 to 8, the partition portion 16 is disposed at locations corresponding to the four corners of the substantially rectangular shape in a plan view inside the main body housing 2. The four partition portions 16 divide the air flow direction downstream portion of the air duct 6 connected to each of the four air outlets 5 from the exhaust port 7 b of the air blower fan 7 into four inside the main body housing 2. .
