Hidden ceiling fan

Abstract

A hidden ceiling fan includes a motor as a power source which has a top end fastened to a ceiling and a spindle connecting to a plurality of vanes. The bottom of the motor has a cover plate. There is a shield plate beneath the vanes to couple with at least one luminous element on the bottom side thereof. The invention provides a shielding function and can agitate air thoroughly to rapidly lower temperature and keep temperature evenly.

1 . A hidden ceiling fan fastened to a ceiling comprising a power source having an outer case fixedly fastened to the ceiling and a spindle connected to a plurality of vanes, the plurality of vanes being to a side of the power source, a cover plate located on the bottom of the power source, and a shield plate located beneath the vanes to mask the vanes having an opening.  
   
   
       2 . The hidden ceiling fan of  claim 1 , wherein the shield plate has a plurality of screw struts on the top to run through respectively an aperture formed on the bottom of a fastening rod and coupled with a nut to fasten the top end of the fastening rod to the ceiling.  
   
   
       3 . The hidden ceiling fan of  claim 1 , wherein each of the vanes is connected to the power source through a rotary arm, the cover plate being formed in a size to shield the rotary arm from being visible.  
   
   
       4 . The hidden ceiling fan of  claim 1 , wherein the shield plate has a diameter greater than the diameter of the vanes, the opening having a diameter smaller than the diameter of the cover plate.  
   
   
       5 . The hidden ceiling fan of  claim 1 , wherein the vane is a flat plate or a plate having a helical surface.  
   
   
       6 . The hidden ceiling fan of  claim 1 , wherein the power source is a motor.  
   
   
       7 . The hidden ceiling fan of  claim 1 , wherein the spindle is between the power source and the ceiling.  
   
   
       8 . The hidden ceiling fan of  claim 1 , wherein the opening in the shield plate is in the center of the shield plate.  
   
   
       9 . The hidden ceiling fan of  claim 1 , wherein the power source has a top and a bottom, the plurality of vanes on the side of the power source failing to be beneath the bottom of the power source.  
   
   
       10 . The hidden ceiling fan of  claim 1 , wherein the power source is in a same plane in which the plurality of vanes rotate.  
   
   
       11 . The hidden ceiling fan of  claim 1 , further including lights provided at a periphery of the shield plate.
