Fine particle diffusion device

摘要

A fine particle diffusion device includes: a first outlet (10a to 10c) through which a first air current is discharged to a space above a living space within a living room; a second outlet (10d) which is arranged below the first outlet (10a to 10c) and through which a second air current is discharged to a space below the first air current; and a fine particle generation device (17) which generates fine particles. Here, the fine particles generated by the fine particle generation device (17) are discharged into the living room, and the concentration of the fine particles discharged through the first outlet (10a to 10c) is lower than the concentration of the fine particles discharged through the second outlet (10d).

主权项

1. A fine particle diffusion device comprising:
an ion generation device including a first ion generation portion that generates only a positive ion and a second ion generation portion that generates only a negative ion; a blower fan; and an air flow path that guides, by driving of the blower fan, the ions generated by the ion generation device to an outlet, wherein the air flow path includes a plurality of lateral division passages whose lateral widths are increased as the lateral division passages extend from an upstream side to a downstream side and which are divided laterally, and the ion generated by the first ion generation portion flows only in a first of the lateral division passages, and the ion generated by the second ion generation portion flows only in a second of the lateral division passages.
