Abstract

A hair treatment system having a hair iron comprising a handle portion and a hair treatment portion, wherein the hair treatment portion comprises an electrically conductive material; an induction oven comprising: an internal cavity into which at least a portion of the hair iron is removably insertable; an induction coil encircling the cavity of the oven; and an alternating current generator electrically connected to the induction coil. A method for heating a hair treatment device with steps: inserting a hair treatment portion of a hair treatment device into a cavity of an induction oven, wherein the hair treatment portion comprises an electrically conductive material; and alternating current in an induction coil of the induction oven, whereby eddy currents are generated on the surface and hysterisis within the metal of the hair treatment portion of the hair treatment device.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A hair treatment system comprising:
 a hair iron comprising a handle portion and a hair treatment portion, wherein the hair treatment portion comprises an electrically conductive material;   an induction oven comprising:   an oven comprising an internal cavity into which at least a portion of the iron is insertable;   an induction coil encircling the cavity of the oven; and   an alternating current generator electrically connected to the induction coil.   
     
     
         2 . A hair treatment system as claimed in  claim 1 , wherein the hair iron comprises a magnetic material. 
     
     
         3 . A hair treatment system as claimed in  claim 1 , wherein the hair iron comprises a material that has an electrical resistivity higher than or equal to steel. 
     
     
         4 . A hair treatment system as claimed in  claim 1 , wherein a shape defined by the cavity of the oven corresponds to a shape defined by the hair treatment portion of the hair iron. 
     
     
         5 . A hair treatment system as claimed in  claim 1 , wherein the induction coil comprises wire. 
     
     
         6 . A hair treatment system as claimed in  claim 1 , wherein the induction coil comprises tubing. 
     
     
         7 . A hair treatment system as claimed in  claim 1 , wherein the alternating current generator generates between 20 kHz and 450 kHz. 
     
     
         8 . A hair treatment system as claimed in  claim 1 , further comprising a magnet positioned adjacent the induction coil. 
     
     
         9 . A hair treatment system as claimed in  claim 1 , further comprising a magnetic layer adjacent the induction coil. 
     
     
         10 . A hair treatment system as claimed in  claim 1 , further comprising an controller in signal communication with the alternating current generator. 
     
     
         11 . A hair treatment system as claimed in  claim 1 , further comprising an temperature monitor in signal communication with the oven, and a duration monitor in signal communication with the alternating current generator. 
     
     
         12 . A hair iron induction oven comprising:
 an oven housing comprising an internal cavity into which at least a portion of the hair iron is insertable, wherein a shape defined by the cavity of the oven corresponds to a shape defined by a hair treatment portion of the hair iron;   an induction coil encircling the cavity of the oven; and   an alternating current generator electrically connected to the induction coil, wherein the alternating current generator generates between 20 kHz and 450 kHz.   
     
     
         13 . A hair iron induction oven as claimed in  claim 12 , wherein the induction coil comprises wire. 
     
     
         14 . A hair iron induction oven as claimed in  claim 12 , wherein the induction coil comprises tubing. 
     
     
         15 . A hair iron induction oven as claimed in  claim 12 , further comprising a magnetic material adjacent the induction coil. 
     
     
         16 . A hair iron induction oven as claimed in  claim 12 , further comprising a controller in signal communication with the alternating current generator, a temperature monitor in signal communication with the oven, and a duration monitor in signal communication with the alternating current generator. 
     
     
         17 . A method for heating a hair treatment device, the method comprising:
 inserting a hair treatment portion of a hair treatment device into a cavity of an induction oven, wherein the hair treatment portion comprises an electrically conductive material; and   alternating current in an induction coil of the induction oven, whereby eddy currents are generated in the hair treatment portion of the hair treatment device.   
     
     
         18 . A method for heating a hair treatment device as claimed in  claim 17 , wherein the alternating current is between 20 kHz and 450 kHz. 
     
     
         19 . A method for heating a hair treatment device as claimed in  claim 17 , further comprising cooling the induction coil by flowing a coolant through the induction coil. 
     
     
         20 . A method for heating a hair treatment device as claimed in  claim 17 , further comprising controlling the duration of the alternating current, and monitoring a temperature of the induction oven.
