As shown in FIG. 2, the main body 1 has a cylindrical shape, has a flange 4 below, and a flange 3 below the flange 4 via a duct 3 from the outside. A circumferential air supply port 6 serving as an indoor side opening for supplying an outdoor air supply flow 5 to the room, a circumferential air intake port 7 for sucking air from the room, and a circumferential blower for blowing air into the room A louver 9 having an outlet 8 is provided, and a suction port 7 is provided on the center side of the louver 9, an outlet 8 is provided on the outer peripheral side thereof, and an air supply port 6 is provided on the outer peripheral side thereof.

  The frame 10 of the main body 1 includes a turbo fan 11 configured to blow air around as a centrifugal fan and an electric motor 12 that rotates the turbo fan 11. A top plate 13 that holds the electric motor 12 is disposed above the frame 10. In addition, the turbofan 11 connected to the electric motor 12 is incorporated below the top plate 13.

  The electric motor 12 may be either direct current (DC) or alternating current (AC).

  Here, the air path configuration inside the frame 10 will be described.

  The air in the room 101 sucks room air from the entire circumference of the suction port 7, is sucked into the turbo fan 11 through the cylindrical path 15 a through the orifice 14, blows out to the whole circumference of the turbo fan 11, and is outside the orifice 14. The circulation air passage 16 that blows downward through the cylindrical passage 15b of the louver 9 and blows out from the entire periphery of the outlet 8 of the louver 9 into the room 101, and the air from the ventilator 103 flows in from the adapter 2, and the circulation air passage A supply air passage 17 that passes through the outside of the air supply 16 and blows out from the supply port 6 to the room 101 is configured.

  Here, the air blown out from the air inlet 6 and the air outlet 8 is blown out along the ceiling 100, that is, the air inlet 6 and the air outlet 8 are directed toward the ceiling, and a part thereof The air exhausted to the outside from the indoor exhaust port 107 is partially sucked into the main body 1 from the suction port 7, whereby the air in the room 101 is circulated.

  Further, in the upper part of the frame 10, a control board 19 for controlling the electric atomizer 18 for generating the electric motor 12 and the ions 22 to mainly control the power supply and the electrostatic atomizer 18 are housed. The control circuit unit 20 is included.

When the air in the room 101 passes through the circulation air passage 16 and blows out from the outlet 8 of the louver 9 to the room 101, the air 22 generated by the electrostatic atomizing means 18 is blown out from the ion outlet 21 of the frame 10. In addition, the ions 22 can be brought into contact with the object 109 to be supplied to the room 101.

  The air flow in the supply air passage 17 is attracted by the air flow in the circulation air passage 16, so that the pressure loss in the supply air passage 17 can be reduced and the ions 22 can be spread throughout the room 101. Therefore, the efficacy of ions can be improved.

  The air supplied in winter approaches the room temperature by exchanging heat with a heat exchange type ventilator, but since it is lower than the room air temperature, it feels cold when a person in the room directly hits it. Further, the temperature of the room 101 has a temperature gradient in which the air temperature increases from the floor to the ceiling, but the temperature gradient is a load for heating and air conditioning.

  The air blown out from the air supply port 6 and the blowout port 8 and the ions 22 discharged from the ion discharge port 21 are mixed and blown upward, thereby reducing the feeling of cold air to the person in the room, and the temperature of the room 101 While reducing unevenness, the ions 22 can be circulated throughout the room 101 to improve the efficacy of the ions 22.

  The air supply grill with an ion generator according to the present invention is useful for an air supply fan or an air supply fan.
