An automatically opening and closing flood-hung windows (1) comprises a suspended mounted flap (5) for closing an opening (4), which is urged by its own weight in an opening (4) position closing, a control lever (13) pivotally mounted on a said opening (4) surrounding structure is mounted, and a float (15) which is coupled to the control lever (13) in order to pivot the latter. The control lever (13) forms a slot (17) for a on the flap (5) provided for engagement projection (16). The slide (17) has a first guide portion (18) for transmitting the weight of the float (15) to the engaging projection (16) for pivoting the flap (5) and a second guide portion (18) for transmitting a lifting force of the float (15) the engaging projection (16) for closing of the flap (5). Such flood-hung windows (1) can be impregnated cheaply manufacture and assemble and is characterized by a reliable closing function and sealing effect.
