Permanent wave treatment method and device

Abstract

A permanent wave treatment device has a heating means ( 3 ) for setting hair of a to-be-treated person in a heated environment, a rod (R) on which the hair is wound and that is formed so that air can flow through it, a suction means ( 4 ) for making the pressure inside the rod negative, and a connection means ( 7 ) for connecting the rod and the suction means.

1 . A permanent wave treatment method, comprising the steps of:
 curling hairs around a rod;   establishing a heating atmosphere with respect to the hairs curled around the rod by heating means; and   in the heating atmosphere state, establishing the inside of the rod at a negative pressure state by suction means, and then, suctioning the heating atmosphere via the hairs, thereby drying the hairs   
   
   
       2 . A permanent wave treatment method as claimed in  claim 1 , wherein the step of stopping the heating by the heating means, followed by suctioning atmospheric air via the hairs by the suction means, thereby cooling the dried and warmed hairs is added. 
   
   
       3 . A permanent wave treatment apparatus, comprising:
 heating means for subjecting hairs of a subject to a heating atmosphere;   a rod for curling hairs formed so as to enable air distribution;   suction means for establishing the inside of the rod at a negative pressure state; and   connecting means for connecting the rod and the suction means with each other.   
   
   
       4 . A permanent wave treatment apparatus as claimed in  claim 3 , wherein the connecting means is composed of a tube having flexibility, and a plurality of the tubes are configured so that they can be removably mounted on the suction means. 
   
   
       5 . A permanent wave treatment apparatus as claimed in  claim 4 , wherein the suction means on which the tubes are to be mounted is configured so as to interrupt air distribution in the case where the tubes are removed. 
   
   
       6 . A permanent wave treatment method as claimed in  claim 4 , wherein the tubes are diverged into many pieces so as to enable connection with a plurality of rods. 
   
   
       7 . A permanent wave treatment apparatus as claimed in  claim 3 , wherein the means for establishing the heating atmosphere is composed of a hood positioned at a head part of a subject and air supply means for supplying hot air into the hood. 
   
   
       8 . A permanent wave treatment apparatus as claimed in  claim 7 , wherein the hood consists of a fixed hood and a hood which is openable so as to enable backward or lateral treatment with respect to the fixed hood, and a hot air blowout port close to the air supply means and a suction port of the suction means are provided at the fixed hood side. 
   
   
       9 . A permanent wave treatment apparatus as claimed in  claim 3 , wherein the means for establishing the airs at the heating atmosphere is used by a radiant heat such as a heater for the head part. 
   
   
       10 . A permanent wave treatment apparatus as claimed in  claim 3 , comprising air and water separating means for separating moisture in the hot air suctioned by the connecting means via the rod. 
   
   
       11 . A permanent wave treatment apparatus as claimed in  claim 3 , wherein the air supply means has a return air supply means for returning the hot air having the moisture removed therefrom in the air by water separating means into the heating atmosphere. 
   
   
       12 . A permanent wave treatment apparatus as claimed in  claim 11 , wherein deodorizing means for adsorbing and decomposing smell of a permanent wave chemical is provided in an air supply passage of the return air supply means. 
   
   
       13 . A permanent wave treatment apparatus as claimed in  claim 3 , wherein the connecting means for connecting the rod and the suction means is formed of a tube having flexibility and one end of the tube is connected to a connecting member formed at one end of the rod, while the other end of the tube is connected to a plurality of accessible connecting portions formed in the suction means. 
   
   
       14 . A permanent wave treatment apparatus as claimed in  claim 3 , wherein the tube and the rod are connected to each other via rotatable means. 
   
   
       15 . A permanent wave treatment apparatus as claimed in  claim 14 , wherein joint means is formed of a ball section connected to the tube side and an engagement hole with which the ball section formed at the rod side is rotatably engaged and a cap for precluding air suctioning is removably mounted on the ball section in a state in which the cap is not engaged with the engagement hole. 
   
   
       16 . A permanent wave treatment apparatus as claimed in  claim 3 , wherein a moisture exhaust wall is formed on an internal face of a closed end side of the rod for discharging the moisture adhering to the hairs to the outside so as to prevent water from being accumulated in the rod. 
   
   
       17 . A permanent wave treatment apparatus as claimed in  claim 3 , wherein the rod is divided into at least two sections along a longitudinal direction. 
   
   
       18 . A permanent wave treatment apparatus as claimed in  claim 17 , wherein the rods is divided into at least two sections along a longitudinal direction, and the divided rod is configured so as not to be separated from each other by a coupling piece. 
   
   
       19 . A permanent wave treatment apparatus as claimed in  claim 16  or  claim 17 , wherein air leakage preventing means for preventing leakage of air while in suctioning operation is provided at a joint of the divided rod. 
   
   
       20 . A permanent wave treatment apparatus as claimed in  claim 3 , wherein at least one or more sensors for measuring a temperature and humidity are mounted at proper positions of the rod or the hood side.
