Hair styling appliance

Abstract

A hair styling appliance has first and second arms coupled together for reciprocal movement towards and away from each other, and arranged to receive hair within a region between each other. A plenum is disposed within at least one of the first arm and the second arm, the plenum including an air inlet for receiving airflow from a fan unit and an air outlet for emitting airflow towards hair within the region. An air deflector is disposed along at least one of the first arm and the second arm, the air deflector being configured to deflect at least some of the airflow out of the region.

1 . A hair styling appliance comprising:
 a first arm and a second arm coupled together for reciprocal movement towards and away from each other, and arranged to receive hair within a region between each other;   a plenum disposed within at least one of the first arm and the second arm, the plenum comprising an air inlet for receiving airflow from a fan unit and an air outlet for emitting airflow into the region; and   at least one air deflector disposed along at least one of the first arm and the second arm, the air deflector being configured to deflect at least some of the airflow out of the region.   
     
     
         2 . The hair styling appliance of  claim 1 , wherein the at least one air deflector at least partly defines at least one duct through which the airflow moves. 
     
     
         3 . The hair styling appliance of  claim 2 , wherein the duct curves away from the region along at least a portion of its length. 
     
     
         4 . The hair styling appliance of  claim 2 , wherein the duct converges, in cross section, in a downstream direction. 
     
     
         5 . The hair styling appliance of  claim 2 , wherein the duct is at least partly defined by an outer surface of the at least one of the first arm and the second arm, disposed opposite the air deflector. 
     
     
         6 . The hair styling appliance of  claim 5 , wherein the outer surface curves, in cross section, away from the region. 
     
     
         7 . The hair styling appliance of  claim 5 , comprising at least one vane disposed between the outer surface and the air deflector. 
     
     
         8 . The hair styling appliance of  claim 7 , wherein the at least one vane is angled and/or curved relative to a longitudinal axis of the at least one of the first and second arms, so as to deflect the airflow exiting the duct, in use, generally towards a tip of the hair styling appliance. 
     
     
         9 . The hair styling appliance of  claim 1 , wherein each of the first and second arms comprises a leading edge, past which hair enters the region while the hair is being pulled through the hair styling appliance in use, and a trailing edge, past which hair leaves the region while the hair is being pulled through the hair styling appliance in use, wherein the air outlet is disposed closer to the trailing edge than the leading edge, and the air deflector is disposed closer to the leading edge than the trailing edge. 
     
     
         10 . The hair styling appliance of  claim 1 , wherein the plenum extends longitudinally through the at least one of the first and second arms, and tapers, in cross section parallel to the plane of the hair within the region, along at least a portion of its length. 
     
     
         11 . The hair styling appliance of  claim 1 , comprising a longitudinally extending heating element for heating the airflow before it is emitted from the air outlet. 
     
     
         12 . The hair styling appliance of  claim 1 , wherein each of the arms comprises the plenum, the air outlet, the air inlet, and the air deflector. 
     
     
         13 . The hair styling appliance of  claim 1 , wherein the first and second arms are pivotably mounted to a base. 
     
     
         14 . The hair styling appliance of  claim 13 , wherein the fan unit is disposed within the base. 
     
     
         15 . The hair styling appliance of  claim 14 , comprising a bellows connecting the or each plenum to the fan unit.
