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).

摘要： A propeller fan includes a boss hub portion and a blade including a front edge portion, a rear edge portion, and an outer edge portion. The outer edge portion has a front outer edge portion, a rear outer edge portion, and a connection portion connecting the front outer edge portion and the rear outer edge portion to each other. In a plan view of the blade along a central axis, a maximum radius R1max of the outer edge portion in a portion corresponding to the front outer edge portion and a maximum radius R2max of the outer edge portion in a portion corresponding to the rear outer edge portion satisfy a condition of R1max>R2max. With such a construction, a propeller fan which generates wind less in pressure fluctuation and is capable of sending comfortable wind and achieving lowering in noise is provided.
