Description

  The present invention relates to an ion generation unit that generates ions in the air and a lighting device including the ion generation unit.

  Conventionally, it is possible to deodorize and disinfect indoor wall surfaces by generating mist from a liquid having a deodorizing action and a sterilizing action and diffusing the mist into the room by an air flow generated using a fan. Air purifiers are in practical use.

However, since such an air cleaner is mainly configured to be installed on the floor surface, a person may trip over the air cleaner and the liquid inside may spill. On the other hand, since a lighting fixture is attached to a relatively high position such as a ceiling or a wall, a lighting fixture in which an air purifier is integrated has been proposed in order to solve the above problem. For example, there has been disclosed a lighting fixture that includes an illumination unit disposed close to at least one of an intake port and an exhaust port and that can discharge fog from the exhaust port (see Patent Document 1).
JP 2006-100218 A

  The lighting apparatus of Patent Document 1 discharges fog generated from a liquid having a deodorizing action or a sterilizing action, and is an ion capable of decomposing bacteria, fungi, harmful substances, etc. floating in the air. Is not intended to spread. Moreover, since there is only one exhaust port, even if the mist can be efficiently discharged near the exhaust port, it is difficult to sufficiently diffuse the mist in the room to which the lighting fixture is attached.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an ion generation unit capable of improving ion diffusibility and an illumination device including the ion generation unit.

  An ion generation unit according to the present invention includes an ion generation unit that generates ions, an air suction port for sucking in air that includes ions generated in the ion generation unit, and a blowout of air that includes the ions. A plurality of air outlets, wherein the plurality of air outlets are provided on the same surface as the air inlet around the air inlet.

  The ion generating unit according to the present invention is characterized in that the plurality of air outlets blow out air containing the ions in different directions.

  The ion generation unit according to the present invention is characterized by including a blowing direction setting member for blowing the air containing the ions in different directions.

  The ion generation unit according to the present invention includes a ventilation path for ventilating the air containing the ions toward the air outlet, and an inner wall of the ventilation path in the vicinity of the air outlet is arranged in a direction of blowing the air outlet. The blowing direction setting member is configured to set the blowing direction by the inclined inner wall.

  In the ion generation unit according to the present invention, the air outlet has a slit shape in which a plurality of partition plates are juxtaposed in an opening, and the partition plate is inclined along a direction in which the air outlet is blown. The blowing direction setting member is configured to set the blowing direction by the inclined partition plate.

  The ion generation unit according to the present invention includes a blade that rotates about an axis orthogonal to the same plane, includes a fan installed in the air passage, and the blowing direction setting member coincides with the rotation direction of the blade. It is comprised so that the blowing direction from each air blower outlet may be set to the direction to do.

  The lighting device according to the present invention includes the ion generation unit according to the above-described invention.

  In the present invention, the ion generation unit is configured to blow out the ion generation unit that generates ions, the air suction port that sucks in air that contains the ions generated in the ion generation unit, and the air that includes the ions. And a plurality of air outlets are provided on the same surface as the air inlet around the air inlet. Note that the same surface includes not only the case where the air inlet and the air outlet are on the same plane, but also the case where the air inlet and the air outlet are on the same bent surface, and on the plane parallel to each other. As a result, the air sucked from the air suction port arranged in the central portion becomes air containing ions inside and is blown out from a plurality of air blowout ports provided around the air suction port. The diffusibility can be improved. In particular, even when the ion generating unit is attached to the ceiling or wall of the room, the plurality of air outlets are provided, so that ions can be efficiently diffused into the room.

  In the present invention, the plurality of air outlets blow out air containing ions in different directions. For example, the directions of the air blown out from each air outlet are different from each other. Thereby, ions can be diffused in all directions from the mounting surface of the air outlet for generating ions.

  In this invention, an ion generation unit is provided with the blowing direction setting member for blowing off the air containing the said ion in a respectively different direction. For example, when the air outlets are arranged at the positions of the four corners of the rectangle, the direction of the air blown out from each air outlet is made to be substantially perpendicular to the blowing direction from the adjacent air outlet. Thereby, ions can be diffused in all directions from the mounting surface of the air outlet for generating ions.

  In the present invention, the ion generation unit includes an air passage that vents air containing ions toward the air outlet, and the inner wall of the air passage near the air outlet is disposed along the air outlet direction. It is inclined and the blowing direction setting member sets the blowing direction by the inclined inner wall. For example, instead of providing the inner wall of the air passage at a right angle to the surface provided with the air outlet, the air containing the ions is blown out by inclining the inner wall of the air passage at a required inclination angle with respect to the surface. The direction can be inclined from the air outlet according to the inclination of the inner wall of the air passage. Thereby, the diffusibility of ions can be further enhanced.

  In the present invention, the air outlet has a slit shape in which a plurality of partition plates are juxtaposed in the opening, and the partition plate is inclined along the outlet direction of the air outlet, and is blown out by the inclined partition plate. Set the direction. For example, rather than providing the partition plate at a right angle to the surface on which the air outlet is provided, the direction of blowing air containing ions is changed to the inclination of the partition plate by inclining at a required inclination angle with respect to the surface. Accordingly, the air outlet can be inclined. Thereby, the diffusibility of ions can be further enhanced.

  In the present invention, the ion generation unit includes a fan having blades rotating around an axis orthogonal to the surfaces of the air outlet and the air inlet in the air passage. By operating the fan, the air sucked from the air suction port is blown out from the air outlet through the air passage. And the blowing direction from each air blower outlet is set to the direction which corresponds with the rotation direction of a blade | wing. For example, when the rotation direction of the fan viewed from the air outlet is counterclockwise, the outlet direction is set so that the outlet direction from each air outlet is counterclockwise. Thereby, air containing ions can be blown out against the flow of spiral air generated by the rotation of the fan, and ion diffusibility can be improved.

  In this invention, an illuminating device is provided with the above-mentioned ion generation unit. Thereby, the illuminating device which integrated the ion generating function excellent in the diffusibility of ion can be provided.

  According to the present invention, ion diffusibility can be improved.

And the blowing direction from each air blower outlet 11-14 is set to the direction which corresponds with the rotation direction (arrow direction of FIG. 12) of a blade | wing. For example, as shown in FIG. 12, when the rotation direction of the fan 33 is counterclockwise, the blowing direction is set so that the blowing direction from each of the air outlets 11 to 14 is counterclockwise. Thereby, air containing ions can be blown out against the flow of spiral air generated by the rotation of the fan 33, and ion diffusibility can be improved.
