Definitions

  • This invention in general relates to electric fans. More particularly this invention relates to a pollution decreasing electric fans with no extra power saving on pollution diseases and energy.
  • Existing electric fans are ceiling fans hung from roof or table/wall/pedestal/ exhaust fans- all having a motor to turn blades for air throw.
  • Ceiling fans have the largest sweep and largest air flow for lowest power.
  • the ceiling fans have a rotating motor with 3-5 blades and suspended on a fan rod hung from the roof. The blades sweep & circulate air with dust all over room.
  • Existing fans are decades old and not meant for polluted air of our cities. Eliminating dust and pathogens saves health and money. There are no simple fans to decrease pollution till date.
  • the number of blades attached to the motor is few- three to six.
  • the object of the invention is to identify the problem associated with the conventional ceiling fans.
  • An extensive search has been carried out using the Internet and related patent specifications were studied for fans with air filtering.
  • the present invention is radically different, with better air flow, dust decrease and cooling too
  • US4840650of Matherene Elmer has a box with filter attached to top of blades by a clamp. Rotating this blade attached box stresses the blades & is inefficient
  • U.S Pat. No. 3,126,263 of L. Schwab titled "Gas Deflecting and Filtering” discloses a fan having filter material which is rotated and through which air passes. As shown in figures, the filter material not only covers the rotating vanes, but also the space between them thereby presenting the appearance of a rotating disc. It would be impractical to cover the multiple blades of a ceiling fan with one large circular disc as described.
  • U.S. Patent No. 4,422,824 issued to C. A. Eisenhardt, Jr. titled “Germicidal Ceiling Fan Blade” discloses a ceiling fan blade having a hollow chamber into which a germicidal light is placed.
  • Filtering pads 2.8 thereof are installed along the leading and trailing edges of each blade enabling air and air-borne micro-organisms to pass into the chamber. Once in the chamber, the germicidal light destroys any micro-organisms contained in the passing air. This adds weight to the blades for a higher weight motor.
  • U.S. Patent No. 4,596,585 of D. W. Moeller, et al. titled “Method and Apparatus for Reduction of Radon Decay Product Exposure” is an ion-generator suspended just below the rotating blades to create special distribution of air-borne charged ions. These ions are used to reduce the amount of the radon decay products suspended in the air.
  • the invention is directed to a novel type of electric ceiling fans with a larger number of blades sweeping the effective sweep area, with fixed filters above the motor, a water evaporative ' cooling in tropics, an ionizer. For same energy, more air flow with healthy air is a new invention.
  • the device comprises of fan rod with a rotating motor.
  • the motor has radial arms with a ring (circular) frame.
  • the ring has larger number of smaller blades in the effective sweep area with low resistance but easy air cutting margins for a larger air flow.
  • the filter of woven or nonwoven mesh traps the dust pollens, pathogens for healthy air.
  • Added ioniser may be placed on the fan rods for health ions with needed electrical connections.
  • the motor may be modified with a lower weight but same rotor and stator by using a plastic enclosure instead of metal.
  • the fan has more air cutting blades with a lighter motor body with same rotor stator weight for same power.
  • a water bottle with a wick connected to a spongy fabric placed above the filter fabric cools in summer.
  • FIG 1 shows in elevation the details of the new fan.
  • FIG. 2 shows the various components.
  • Figure 3 shows modification with water evaporating cooling.
  • Figure 4 shows a normal fan
  • Fig 4 Existing ceiling fans in Fig 4 has a fan rod (1) with a motor (2) with 3-4 blades (5) attached at the center. As the fan motor rotates the blades rotate spreading air with dust all over the room. There are no filters too for clean air. The air delivered is determined by the speed of rotation and air cutting area of blades. Only the outer half of fan produces the entire air sweep.
  • the new device has a fan rod with an upper clamp for the roof hook.
  • the motor has a ring with a larger number of blades with a higher air cutting area.
  • a filtering fabric is attached to the fan rod as a canopy above the blades.
  • An added ionizer may be clamped to the rod.
  • the device comprises of a fan rod (1) with a top clamp for the roof hook.
  • the lower end has a motor (2).
  • the motor has a ring (3) with radial arms (4) fixed to the motor.
  • the ring carries a number of plastic/ aluminum blades (5) of smaller size with easy air cutting edges.
  • the air delivered is more as the blades are more in number.
  • a filter fabric (6) is spread on supporting radial rods (7) which are fixed at the central end on the fan rod by a clamp (8).
  • the filter assembly forms a canopy over the blades.
  • the fabric may be woven or nonwoven plastic meshed fabric for reuse.
  • the large pores may be used for non asthmatics, smaller for severe asthmatics to trap all the dust, pollens or pathogens.
  • the filter may decrease air flow but the added blades give more air for same power & efficiency.
  • the motor may be modified.
  • the motor has an upper (9) and lower (10) plastic not metal casing with a central stator (11) and a peripheral rotor (12).
  • the stator has a central , hollow rod (13) fixed to lower end of fan rod (1).
  • the stator and rotor of same weight of existing technology may be used.
  • Plastic casing instead of heavy metal 'casing helps for energy saving.
  • a few holes (18) in the casing dissipate motor heat.
  • Added ionizer (14) may be fixed to the fan rod or at the center of fan motor rod (13). This is connected to the fan main circuit for releasing ions when in use.
  • Added cooling can be made with a plastic water bottle (15) fitted to the lower end of stator hollow rod (13).
  • a wick (16) lifts water to a spongy fabric (17) spread over the top of filter and evaporates producing ' the cooling.
