Abstract
A grille is provided at a lower end portion of an air inlet, and covers a central portion of the air inlet to form an inlet opening between an outer peripheral edge of the grille and an opening edge of the air inlet in plan view. A plate member extends along an inner surface of the air inlet, and provided inside the air inlet such that an upper edge of the plate member is located more inward than a lower edge of the plate member. The upper edge of the plate member is located above the lower end of the air inlet. The lower edge of the plate member surrounds an outer periphery of the grille in plan view.
