Hair curling iron

Abstract

A hair curling iron including a lower case composed of a lower grill part and a lower heating part, a lower closing part which closes the top side of the lower case's lower grill part, a lower heater installed inside the lower heating part of the lower case in which the lower closing part has been assembled, an upper grill part and an upper heating part composing the upper case, an upper closing part which closes the bottom side of the upper grill part of the upper case. The hair curling iron is composed of the upper heater installed inside the upper heating part of the upper case in which the upper closing part has been assembled. A rounded concave part composing the surface for hair to be easily curled by being installed in the lower heating part of the lower case, a concave heat plate on both sides equipped with a lower exposed part which is exposed on both sides of the lower case and composed of the block part in the surface in order to more smoothly curl hair by contacting the surface of the concave part of the concave heating plate. A block heating plate construction include an upper exposed part that is exposed to both sides of the upper case on both sides. According to this hair curling iron, a block part is formed in the block heating plate installed in the upper case and a concave part is formed in the concave heating plate installed in the lower case and therefore able to not only curl hair more effectively. Also, as the block heating plate's exposed part is larger than the concave heating plate's exposed part, the block heating plate and the concave heating plate generally maintain the same temperatures, thereby more effectively curling the hair.

1 . A hair curling iron, comprising: 
 an upper case;    a lower case connected to the upper case;    a convex heating plate installed in the upper case and having an exposed convex part;    a concave heating plate installed in the lower case and having an exposed concave part associated with the convex part; and    the convex part being larger than the concave part such that the convex heating plate and the concave heating plate maintain generally the same temperature.    
   
   
       2 . The hair curling iron of  claim 1  wherein the convex heating plate and the concave heating plate maintain the same temperature of approximately 160-170 degrees Centigrade during a hair curling treatment.  
   
   
       3 . The hair curling iron of  claim 1  wherein the exposed surface area of the convex part is approximately 1.6 square centimeters larger than that of the concave part.  
   
   
       4 . The hair curling iron of  claim 1  wherein the convex part has an area of approximately 24.8 square centimeters and the concave part has an area of approximately 23.2 square centimeters.  
   
   
       5 . A hair curling iron, comprising: 
 an upper case;    a block heating plate installed in the upper case;    a block part formed in the block heating plate;    a lower case associated with the upper case;    a concave heating plate installed in the lower case; and    a concave part formed in the concave heating plate.    
   
   
       6 . A hair curling iron, comprising: 
 an upper case;    a lower case connected to the upper case; and    a convex heating plate having an upper part that is exposed to both sides of the upper case.
