Cooling/heating fan apparatus

Abstract

A cooling/heating fan apparatus includes a protective shade, a fan motor having a propeller shaft extended into the protective shade, an impeller mounted on a distal end of the propeller shaft, at least one porous ceramic carrier mounted on the propeller shaft and located between the fan motor and the impeller, wherein the porous ceramic carrier has a plurality of through holes each having a surface provided with an electro-thermal plating film layer. Thus, the air from the ambient environment is heated by the electro-thermal plating film layer quickly, thereby enhancing the heating efficiency of the fan apparatus.

1 . A fan apparatus, comprising: 
 a protective shade;    a fan motor mounted on the protective shade and having a propeller shaft extended into the protective shade;    an impeller mounted on a distal end of the propeller shaft of the fan motor;    at least one porous ceramic carrier mounted on the propeller shaft of the fan motor and located between the fan motor and the impeller;    wherein, the porous ceramic carrier has a plurality of through holes each having a surface provided with an electro-thermal plating film layer.    
   
   
       2 . The fan apparatus in accordance with  claim 1 , wherein the porous ceramic carrier is formed integrally.  
   
   
       3 . The fan apparatus in accordance with  claim 2 , wherein the porous ceramic carrier is formed integrally by an extrusion process.  
   
   
       4 . The fan apparatus in accordance with  claim 1 , wherein the porous ceramic carrier has a circular shape.  
   
   
       5 . The fan apparatus in accordance with  claim 1 , wherein an air from the ambient environment is heated by the electro-thermal plating film layer of each of the through holes of the porous ceramic carrier and to produce a hot air which is carried outward by the impeller to provide a warming effect.  
   
   
       6 . The fan apparatus in accordance with  claim 1 , further comprising a fixing seat mounted in the protective shade for fixing the porous ceramic carrier.  
   
   
       7 . The fan apparatus in accordance with  claim 1 , further comprising an auxiliary fan mounted on a rear end of the fan motor to introduce an ambient air into the fan motor so as to cool the fan motor.  
   
   
       8 . The fan apparatus in accordance with  claim 1 , wherein the through holes of the porous ceramic carrier are formed by a plurality of intersecting separation walls having cylindrical connections.  
   
   
       9 . The fan apparatus in accordance with  claim 8 , wherein each of the through holes of the porous ceramic carrier has a plurality of arc-shaped corners.  
   
   
       10 . The fan apparatus in accordance with  claim 8 , wherein the intersecting separation walls are arranged in a staggered perpendicular manner.  
   
   
       11 . The fan apparatus in accordance with  claim 1 , wherein the fan apparatus comprises a plurality of porous ceramic carriers surrounding the propeller shaft of the fan motor.  
   
   
       12 . The fan apparatus in accordance with  claim 11 , wherein the porous ceramic carriers are arranged in an annular manner.  
   
   
       13 . The fan apparatus in accordance with  claim 11 , wherein the propeller shaft of the fan motor is located at a center of the porous ceramic carriers and is extended through a gap defined between the porous ceramic carriers.  
   
   
       14 . The fan apparatus in accordance with  claim 1 , wherein the porous ceramic carrier has a central portion formed with a mounting hole mounted on the propeller shaft of the fan motor.
