Abstract

The invention is an improved ceiling fan for cleaning polluted air. A fan rod (1) has upper clamp for roof and a lower motor (2). The motor has a ring (3) supported on radial arms (4) fixed to the motor (2). The ring has multiple smaller blades (5) for more air sweeping. A woven or nonwoven washable filter fabric (6) with needed pores mounted on radial rods (7) fixed to a clamp (8) on the fan rod (1) forms air purifying canopy above the motor and blades. The motor is modified with a lower weight plastic casing with heat radiating holes (18). More number of blades with lower weight motor gives more air for same power. Ionizer (14) is fixed to fan rod (1). Water bottle (15) with wick (16) spreading water on an evaporating sponge (17) spread above the filter cools air in hot summer for cool healthy air.

Claims

AMENDED CLAIMS received by the International Bureau on 29 December 2008 (29.12.08)
1.An improved electric ceiling fan with improvements in increased number of air circulating blades, an efficient motor, easy detachable filter, an ioniser and an evaporating cooling attachment, the said ceiling fan comprises of a fan rod(l)having an upper roof clamp and a lower motor(2), the said fan motor(2) enclosed in plastic casing with cooling holes, the said motor(2) has more than two radial arms(4) , the said radial arms(4) supporting a fan blade ring(3), the said fan blade ring(3) having larger number of air circulating blades (5), the said fan rod has a washable dust trapping filter fabric (6 ) mounted on fabric rods(7) detachably fixed to a central clamp(8) fixed on to the said fan rod(l) above the said blades and motor, the said fan rod also carrying a negative ion releasing ionizer(14) below the said filter fabric, said ceiling fan circulating a cool, clean air with negative ions.
2. An improved electric ceiling fan as claimed in claim 1, wherein the filter fabric(6 ) is a woven or nonwoven washable plastic mesh with needed small pores to filter the dust with clean air flow, the said fabric is fitted on supporting fabric radial rods (7 ), the said fabric radial arms detachably fixed in the clamp (8) of the fan rod(l) for easy removal and refitting for years of use.
3. An improved electric ceiling fan as claimed in claim 1, wherein the said fan blade ring (3) has two or more radial arms (4) to fix to the said motor casing(9) by screws at the inner end, the said ring having many blades(5) firmly fixed for air circulation.
4. An improved electric ceiling fan as claimed in claim 1, wherein the blades (5) of chosen size and air cutting edges are fixed to the fan blade ring (3) firmly for years of air circulation.
5. An improved electric ceiling fan as claimed in claim 1, wherein a water bottle (15) with a wick(16) , is fixed to stator rod bottom(13 ) , the said wick lifts water by capillary to a evaporating sponge(17 ) for real cooling, the said sponge being spread above the said filter cloth(6).
6. An improved electric ceiling fan as claimed in claim 1 wherein the said ionizer(14) is attached to the fan rod(l ) or the lower end of stator rod(13 ) and connected to electrical circuit for healthy negative ions.
7. An improved electric ceiling fan as claimed in claim 1 wherein the motor(2) has an upper( 9) and lower (10 ) plastic( lower weight) casing with the inner stator and rotor, the said casing has threaded holes for radial arms fixing screws(4), the said casing having holes (18) for motor cooling.
