Abstract
Abstract An air circulating device for providing a constant movement of air within the occupant zone of rooms which do not contain openable windows to allow natural air circulation during hot days. The air circulating device is provided in two forms, each form preferably situated in the corner of the room, the first form comprising a vertical air chamber with a first air inlet positioned adjacent the floor of the room and two air outlets positioned so that air forced from the vertical air chamber will flow outward in divergent paths along each of the walls forming a corner of the room, the inlet pulling in air diagonally from within the occupant zone of the room, providing complete air circulation. The second form of the air circulating device comprising top and bottom air inlets and a pair of air outlets in which air is forced through the outlets in divergent paths diagonally into the occupant zone of the room, the top and bottom inlets and spaced outlets are spaced intermediate the floor and ceiling of the room. In both forms of the air circulating device, the inlet is provided with a double filter in which the first stage comprises a washable synthetic filter for removing particulate material from the air, the second stage comprising an activated carbon filter which is replaceable and which removes smoke and other odors from the air.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
171 words
An air circulating device for providing circulation of air throughout substantially the total area of a room, comprising: a hollow base forming the bottom portion of said device and capable of supporting said device adjacent to the floor of a room, an air inlet means formed in said base and capable of receiving air flowing parallel and adjacent to the floor, a single blower assembly contained within said base and including an impeller enclosed within a blower housing, said blower housing including a blower outlet, a casing comprising an elongated vertical air chamber disposed over said hollow base, first and second elongated vertical air outlets placed in said casing and positioned and arranged on opposite sides of said casing so as to provide at least two divergent substantially horizontal airflow paths, said blower outlet being orientated upwardly into said air chamber and being contiguous therewith, whereby forced air is discharged from said air chamber into said at least two divergent substantially horizontal paths directly from said air outlets into a room.
Claim 2
Dependent Claim
171 words
An air circulating device for providing circulation of air throughout substantially the total area of a room, comprising: a hollow base forming the bottom portion of said device and capable of supporting said device adjacent to the floor of a room, an air inlet means formed in said base and capable of receiving air flowing parallel and adjacent to the floor, a single blower assembly contained within said base and including an impeller enclosed within a blower housing, said blower housing including a blower outlet, a casing comprising an elongated vertical air chamber disposed over said hollow base, first and second elongated vertical air outlets placed in said casing and positioned and arranged on opposite sides of said casing so as to provide at least two divergent substantially horizontal airflow paths, said blower outlet being orientated upwardly into said air chamber and being contiguous therewith, whereby forced air is discharged from said air chamber into said at least two divergent substantially horizontal paths directly from said air outlets into a room.
Claim 3
Dependent Claim
36 words
