Definitions

  • the present invention relates to a fan apparatus, and more particularly to a cooling/heating fan apparatus.
  • a conventional heater comprises a quartz tube that functions as a heat source to produce a hot air so as to provide a warming effect.
  • the quartz tube bums the oxygen in the air, so that the conventional heater is not suitable for a closed space in the room.
  • Another conventional heater comprises a heating element made of PTC ceramic material.
  • the PTC ceramic material is expensive, thereby greatly increasing costs of fabrication.
  • Another conventional heater comprises a halogen lamp that functions as a heating element.
  • the halogen lamp is directly projected onto the human body, so that the human body is easily burned by the high temperature produced by the halogen lamp, thereby causing danger to the user.
  • the primary objective of the present invention is to provide a cooling/heating fan apparatus.
  • Another objective of the present invention is to provide a fan apparatus, wherein the air from the ambient environment is heated by the electro-thermal plating film layer quickly, so that the electro-thermal plating film layer has an accelerated thermal cycle, thereby enhancing the heating efficiency of the fan apparatus.
  • a further objective of the present invention is to provide a fan apparatus, wherein the air from the ambient environment is heated by the electro-thermal plating film layer evenly and safely without needing to burn the oxygen, thereby protecting the user when using the fan apparatus.
  • a further objective of the present invention is to provide a fan apparatus, wherein the intersecting separation walls have cylindrical connections so that each of the through holes of the porous ceramic carrier has a plurality of arc-shaped corners to reduce the stress applied on the connections of the intersecting separation walls, thereby preventing the connections of the intersecting separation walls from being worn or broken due to a stress concentration.
  • the porous ceramic carrier 4 is formed integrally by an extrusion process and has a plurality of through holes 40.
  • the porous ceramic carrier 4 has a circular shape.
  • Each of the through holes 40 of the porous ceramic carrier 4 has a surface provided with an electro-thermal plating film layer 41 formed by a thermal chemical reaction method, such as a high temperature atomized growth method.
  • the electro-thermal plating film layer 41 is made of a resistance material, such as tin, nickel chromium alloy, copper nickel alloy, copper nickel manganese alloy and the like.
  • the air from the ambient environment is heated by the electro-thermal plating film layer 41 of each of the through holes 40 of the porous ceramic carrier 4 and to produce a hot air which is carried outward by the impeller 3 to provide a warming effect.
  • the air from the ambient environment is heated by the electro-thermal plating film layer 41 quickly, evenly and safely without needing to bum the oxygen, thereby protecting the user when using the fan apparatus.
  • the electro-thermal plating film layer 41 has an accelerated thermal cycle, thereby enhancing the heating efficiency of the fan apparatus.
  • the through holes 40 of the porous ceramic carrier 4 are formed by a plurality of intersecting separation walls 43 which are arranged in a staggered perpendicular manner.
  • the intersecting separation walls 43 have cylindrical connections 44 so that each of the through holes 40 of the porous ceramic carrier 4 has a plurality of arc-shaped corners 400 to reduce the stress applied on the connections 44 of the intersecting separation walls 43, thereby preventing the connections 44 of the intersecting separation walls 43 from being worn or broken due to a stress concentration.
  • the fan apparatus comprises a plurality of (preferably five) porous ceramic carriers 4 surrounding the propeller shaft 10 of the fan motor 1 and arranged in an annular manner.
  • the propeller shaft 10 of the fan motor 1 is located at a center of the porous ceramic carriers 4 and is extended through a gap "A" defined between the porous ceramic carriers 4.
  • the porous ceramic carrier 4 has a central portion formed with a mounting hole 42 mounted on the propeller shaft 10 of the fan motor 1.
  • a conventional porous ceramic carrier 5 in accordance with the prior art has a plurality of through holes 50 formed by a plurality of intersecting separation walls 51 having sharp connections 52.
  • the stress is applied on the sharp connections 52 of the intersecting separation walls 51, so that the sharp connections 52 of the intersecting separation walls 51 are easily worn or broken due to a stress concentration.
  • the air from the ambient environment is heated by the electro-thermal plating film layer 41 quickly, so that the electro-thermal plating film layer 41 has an accelerated thermal cycle, thereby enhancing the heating efficiency of the fan apparatus.
  • the air from the ambient environment is heated by the electro-thermal plating film layer 41 evenly and safely without needing to bum the oxygen, thereby protecting the user when using the fan apparatus.
  • the intersecting separation walls 43 have cylindrical connections 44 so that each of the through holes 40 of the porous ceramic carrier 4 has a plurality of arc-shaped corners 400 to reduce the stress applied on the connections 44 of the intersecting separation walls 43, thereby preventing the connections 44 of the intersecting separation walls 43 from being worn or broken due to a stress concentration.
