Selectively joined hair drying apparatus and method for drying hair

Abstract

A hair dryer in which a first air blower ( 12 ) having a mating surface ( 44 ) with recesses ( 46 a, 46 b ) selectively engages a second air blower ( 14 ) having an opposing mating surface ( 52 ) with lugs ( 54 a, 54 b ) that are received in the recesses, each air blower ( 12 ) and ( 14 ) having a fan motor for operating a fan and a housing ( 20 ), ( 22 ) with an air inlet ( 24 ) and an air outlet ( 26 ), for selective operation for directing air in a common direction or detached for operation for directing air in independent separate directions.

What is claimed is:  
     
         1 . A hair dryer, comprising: 
 a first air blower and a second air blower, each having a motor for operating a fan, and a housing with an air inlet and an air outlet; and    means for selectively detachably engaging the first air blower and the second air blower for communicating air in a common direction or being detached for communicating air in independent directions.    
     
     
         2 . The hair dryer as recited in  claim 1 , wherein means for selectively detachably engaging comprises the first air blower having a mating surface of a first character and a second air blower having a mating surface of a second character.  
     
     
         3 . The hair dryer as recited in  claim 1 , 
 wherein the mating surface of the first character defines at least one recess that is partially closed by a portion of the mating surface; and    wherein the mating surface of the second character comprises at least one projection configured for being received into the recess and held by the portion of the mating surface,    whereby the first air blower and the second air blower are selectively joined together by engaging the projection in the recess.    
     
     
         4 . The hair dryer as recited in  claim 3 , wherein the recess is a T-shape configuration.  
     
     
         5 . The hair dryer as recited in  claim 1 , wherein the first air blower and the second air blower connect though electrical cords to a common plug for engaging a supply of electrical current.  
     
     
         6 . A hair dryer, comprising a first air blower having a mating surface of a first character and a second air blower having a mating surface of a second character, each of the first air blower and the second air blower have a motor for operating a fan and a housing with an air inlet and an air outlet, the first air blower and the second air blower being selectively detachably connected together by engaging the opposing mating surfaces.  
     
     
         7 . The hair dryer as recited in  claim 6 , 
 wherein the mating surface of the first character defines at least one recess that is partially closed by a portion of the mating surface; and    wherein the mating surface of the second character comprises at least one projection configured for being received into the recess and held by the portion of the mating surface,    whereby the first air blower and the second air blower are selectively joined together by engaging the projection in the recess.    
     
     
         8 . The hair dryer as recited in  claim 7 , wherein the recess is a T-shape configuration.  
     
     
         9 . The hair dryer as recited in  claim 6 , wherein the first air blower and the second air blower connect though electrical cords to a common plug for engaging a supply of electrical current.  
     
     
         10 . A method of drying hair, comprising the steps of: 
 (a) providing a first air blower having a mating surface of a first character and a second air blower having a mating surface of a second character, each of the first air blower and the second air blower have a motor for operating a fan, and a housing with an air inlet and an air outlet; and    (b) connecting the opposing mating surfaces of the first air blower and the second air blower for operating the first and the second air blowers as a single unit for directing air in a common direction.    
     
     
         11 . The method as recited in  claim 10 , where the step (b) connecting comprises the step of (c) inserting a projection from the mating surface of the second air blower into a recess defined by the mating surface of the first air blower.  
     
     
         12 . The method as recited in  claim 11 , where the step (b) connecting further comprises the step of (d) moving the second air blower relative to the first air blower to lock the first air blower and the second air blower together.  
     
     
         13 . The method as recited in  claim 10 , further comprising the step of detaching the first air blower and the second air blower from engagement for independent operation thereof, whereby the first air blower and the second air blower are independently operable to direct air in respective first and second direction towards a person for drying hair.  
     
     
         14 . The method as recited in  claim 10 , further comprising the step of connecting the first air blower and the second air blower though electrical cords to a common plug for engaging a supply of electrical current.
