Abstract
Abstract Air-circulating device having an upright tube or passage and a fan for drawing warm air downward from adjacent the ceiling of a room and discharging it adjacent the floor thereof is provided with a liquid reservoir and a wick, with the wick positioned so that the circulating air blows thereover to provide air freshening and humidifying. The reservoir may be adjacent the tube above the fan or may be adjacent the fan outlet. A further modification provides a charcoal or other type filter in the air stream to remove odors, such as cigarette smoke, etc.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
A portable air-circulating and humidifying device comprising: a fan housing, a fan blade and a fan motor associated with said fan housing to draw air through said housing; walls defining an outlet space below said fan housing for delivering air from said fan housing back into said from below said air inlet to circulate air in the room and reduce stratification; a wick and a liquid reservoir, said reservoir being positioned on top of said fan housing and having an inner tubular air passage therethrough, an inlet tube detachably mounted on top of said reservoir and in communication with said air passage therethrough, said inlet tube serving as an air inlet passage to said reservoir and said housing, said air inlet tube extending upward from said housing to an elevated position for withdrawing air from above said fan housing, said inner tubular air passage through said reservoir extending between said inlet tube and said fan housing, said wick extending into said air passage within said reservoir.
Claim 2
Dependent Claim
166 words
A portable air-circulating and humidifying device comprising: a fan housing, a fan blade and a fan motor associated with said fan housing to draw air through said housing; walls defining an outlet space below said fan housing for delivering air from said fan housing back into said from below said air inlet to circulate air in the room and reduce stratification; a wick and a liquid reservoir, said reservoir being positioned on top of said fan housing and having an inner tubular air passage therethrough, an inlet tube detachably mounted on top of said reservoir and in communication with said air passage therethrough, said inlet tube serving as an air inlet passage to said reservoir and said housing, said air inlet tube extending upward from said housing to an elevated position for withdrawing air from above said fan housing, said inner tubular air passage through said reservoir extending between said inlet tube and said fan housing, said wick extending into said air passage within said reservoir.
Claim 3
Dependent Claim
18 words
The device of claim 1 wherein said reservoir is annular with an air passage adjacent the center thereof.
Claim 4
Dependent Claim
191 words
A portable air-circulating and humidifying device comprising: a fan housing, a fan blade and a fan motor associated with said fan housing to draw air through said housing; an inlet tube detachably mounted on top of said fan housing to serve as an air inlet passage to said fan housing, said air inlet tube extending upward from said housing to an elevated position for withdrawing air above said fan housing; an outlet space below said fan housing and a diffuser wall below said fan housing defining said outlet space so that said fan housing discharges air onto said diffuser wall from above and said diffuser wall has a generally radially outward directed outlet space below said fan housing for delivering air from said fan housing back into said room below the air inlet to circulate air in the room and reduce stratification; and a wick and a liquid reservoir, said reservoir having support means therein for supporting said diffuser, said wick extending upward out of said reservoir and being positioned outwardly from said diffuser so that air from said fan housing is delivered outwardly through said wick to humidify the air.
Claim 5
Dependent Claim
191 words
A portable air-circulating and humidifying device comprising: a fan housing, a fan blade and a fan motor associated with said fan housing to draw air through said housing; an inlet tube detachably mounted on top of said fan housing to serve as an air inlet passage to said fan housing, said air inlet tube extending upward from said housing to an elevated position for withdrawing air above said fan housing; an outlet space below said fan housing and a diffuser wall below said fan housing defining said outlet space so that said fan housing discharges air onto said diffuser wall from above and said diffuser wall has a generally radially outward directed outlet space below said fan housing for delivering air from said fan housing back into said room below the air inlet to circulate air in the room and reduce stratification; and a wick and a liquid reservoir, said reservoir having support means therein for supporting said diffuser, said wick extending upward out of said reservoir and being positioned outwardly from said diffuser so that air from said fan housing is delivered outwardly through said wick to humidify the air.
Claim 6
Dependent Claim
24 words
The device of claim 3 wherein said fan housing is directly supported on said diffuser and said diffuser is directly supported within said reservoir.
