Hair dryer

Abstract

The present invention relates to hair dryer having a fan and a heater. The hair dryer has a PCB board having programmable integrated circuit (IC) components mounted thereon, wherein the fan and the heater are also connected to the PCB board; a plurality of presets defining operating levels of the fan and the heater, alone or in any combinations; a multi-mode switch connected to the PCB board for controlling the plurality of presets, the multi-mode switch is positioned at an one-hand operable location on the hair dryer, wherein user is able to operate the hair dryer with only a hand holding hair dryer and controlling the plurality of presets through the multi-mode switch.

1 . A hair dryer having a fan and a heater, the hair dryer comprising:
 a PCB board having programmable integrated circuit (IC) components mounted thereon, wherein the fan and the heater are also connected to the PCB board;   a plurality of presets defining operating levels of the fan and the heater, alone or in any combinations;   a multi-mode switch connected to the PCB board for controlling the plurality of presets, the multi-mode switch is positioned at an one-hand operable location on the hair dryer, wherein user is able to operate the hair dryer with only a hand holding hair dryer and controlling the plurality of presets through the multi-mode switch.   
   
   
       2 . The hair dryer according to  claim 1 , wherein the multi-mode switch is a rotary dial. 
   
   
       3 . The hair dryer according to  claim 1 , wherein the multi-mode switch is a toggle switch. 
   
   
       4 . The hair dryer according to  claim 3 , wherein the toggle switch is toggleable in an up-down direction. 
   
   
       5 . The hair dryer according to  claim 3 , wherein the toggle switch is toggleable in a left-right direction. 
   
   
       6 . The hair dryer according to  claim 3 , wherein the toggle switch is an omni-directional toggle switch that is able to toggle in at least up-down and left-right directions. 
   
   
       7 . The hair dryer according to  claim 1 , wherein the multi-mode switch is a push button. 
   
   
       8 . The hair dryer according to  claim 7 , wherein the push button comprises a first button and a second button, or the push button is a single button. 
   
   
       9 . The hair dryer according to  claim 1 , wherein the multi-mode switch comprises a combination of any one of the above multi-mode switches. 
   
   
       10 . The hair dryer according to  claim 1 , wherein the multi-mode switch is located on an upper side of the handle of the hair dryer. 
   
   
       11 . The hair dryer according to  claim 1 , further comprising a far infrared emitter connected to the PCB board, wherein its operating status is defined in one of the presets. 
   
   
       12 . The hair dryer according to  claim 1 , further comprising an ionic generator connected to the PCB board, wherein its operating status is defined in one of the presets. 
   
   
       13 . The hair dryer according to  claim 1 , wherein the PCB further comprises a switch mode power supply unit. 
   
   
       14 . The hair dryer according to  claim 1 , wherein the PCB includes an auto-cut-off circuit.
