Kind Code:

Abstract:
An air purifier that purifies air taken in from outside by a fan and blows the air from an outlet (17), wherein the outlet (17) is horizontally long, and the vertical width (H1) at the center in the widthwise direction is wider than the vertical width (H2) at the edges. A plurality of air-directing plates (17a) are arranged side-by-side in a horizontal direction in the outlet (17) at intervals, the plate surfaces of said air-direction plates being in a vertical position that extends in the vertical direction and along the direction in which the air is blown. The closer the position of the plate surface to an end of the outlet in the horizontal direction, the more the plate surface faces towards the outflow side and opens towards the outside in the horizontal direction. The air purifier has an air passage which has one end in the air flow direction connected to the inflow side of the outlet (17), and the cross-section of which perpendicular to the air flow direction is horizontally long. The abovementioned fan is a crossflow fan arranged in the air passage so that the rotary shaft is oriented along the lengthwise direction of the horizontally long cross section of the air passage.
