Air circulator and air filtration device
First Claim
1. An air circulator for providing circulation of air substantially throughout the total area of a room comprising a housing supported vertically at a corner of the room intermediate the floor and ceiling with the housing including an air inlet at the upper end portion thereof and an air inlet at the lower end portion thereof, said housing including a rear wall extending alongside of the surfaces of the walls which intersect to form the corner of the room and an air outlet along each opposite side portion thereof for discharging air in a horizontal direction generally parallel to and adjacent the surfaces of the walls which intersect to form the corner of the room, blower means interiorly of the housing for discharging substantially equal volumes of air from each outlet at substantially equal velocities.

Abstract
An air circulator and air filtration device for a room or other enclosed space supported in the corner thereof intermediate the floor and ceiling and including an upwardly opening top air inlet and a downwardly opening bottom air inlet with each inlet including a filter assembly and a pair of discharge outlets for discharging air horizontally in a path generally parallel to and adjacent the walls which intersect to form the corner in which the air circulator is mounted. The air circulator includes a single motor and an upper and lower blower assembly driven by the motor with the upper blower assembly communicating only with the upper air inlet and discharging toward one of the air outlets and the lower blower assembly communicating only with the bottom inlet and discharging toward the other of the outlets for maintaining a substantially constant and equal volume of air discharged along each of the intersecting walls of the room for effective circulation of air throughout the room and substantially eliminating temperature stratification in the room. Each air inlet filter assembly includes a foam pre-filter and an activated carbon filter for cleaning and purifying air being circulated.

- 1. An air circulator for providing circulation of air substantially throughout the total area of a room comprising a housing supported vertically at a corner of the room intermediate the floor and ceiling with the housing including an air inlet at the upper end portion thereof and an air inlet at the lower end portion thereof, said housing including a rear wall extending alongside of the surfaces of the walls which intersect to form the corner of the room and an air outlet along each opposite side portion thereof for discharging air in a horizontal direction generally parallel to and adjacent the surfaces of the walls which intersect to form the corner of the room, blower means interiorly of the housing for discharging substantially equal volumes of air from each outlet at substantially equal velocities.
- 8. An air circulating device for providing circulation of air throughout substantially the total area of a room, comprising a housing defining an enclosed air chamber, a first upwardly facing top air inlet, a second downwardly facing bottom air inlet, first and second air outlets in said housing intermediate said top and bottom air inlets, blower means positioned within said air chamber intermediate said top and bottom air inlets, said blower means including vertically spaced impellers with a drive motor therebetween and drivingly connected thereto, each impeller being enclosed within an impeller housing, each impeller housing including a horizontally directed discharge, said first and second air outlets being positioned in outwardly facing diverging directions, one of said impeller housing discharges being spaced from and directed toward said first air outlets, the other of said impeller housing discharges being spaced from and directed toward said second air outlet whereby forced air discharged from said impeller housing discharges is directed toward and discharged from said first and second air outlets, respectively.
- 11. In combination with a room including angularly disposed walls defining a corner of the room, an air circulator mounted in the corner of the room in vertically spaced relation to a floor and a ceiling, said air circulator including a vertically disposed housing having a hollow interior chamber with an upwardly facing air inlet and a downwardly facing air inlet communicating with the interior of the housing, said housing including vertically elongated outlets facing in divergent directions and generally discharging air in directions generally paralleling the room walls, said housing including vertically spaced horizontal partitions forming closures for the interior of the housing above said below the air outlets, each partition including an opening defining an air inlet communicating with the housing air inlets, air filtering means in each of the housing air inlets, a blower mounted on each of said partitions on the inward side thereof and having an inlet communicating with the opening in the partition, each blower including an air discharge directed toward one of the air outlets, means in said housing drivingly connected to the blowers for actuating the blowers for moving air from the air inlets to the air outlets, each blower air discharge including a discharge opening facing outwardly in the direction of one of said outlets and oriented in spaced relation thereto and in alignment with the end portion of the air outlet for discharging high velocity air toward the end portion of the air outlet and pressurizing the chamber for discharge of air throughout the length of the air outlets thereby providing air circulation throughout the length of the air outlets thereby providing air circulation throughout the room.
