The object of the present invention is to provide a dehumidifier for increasing the inhalation face, such that the dehumidification may still be effective even if any three of the faces at the front, rear, and opposing sides thereof are obstructed by walls or furniture. The solution of the present invention is that a casing is formed of a rectangular configuration along its front and rear directions, and a front and rear portion of the body casing is formed such that their widths are reduced from the central portion while approaching the front or rear end. Further, on the opposing sides of the reduced width span of the front portion of the body casing is formed thereon with two inhaling ports. On the rear portion of the reduced width span of the rear portion of the body casing is formed with an inhaling port stretching into one of the sides. |
