Hand hair dryer with two handle grips
View Patent ↗The invention relates to a hand hair dryer ( 1 ), comprising an electric fan ( 2 ) and an in-series electric heating device ( 3 ), for the generation of an air stream ( 4 ) out of a tube section ( 5 ), whereby the fan ( 2 ) is arranged in a housing section ( 6 ) and the heating device ( 3 ) arranged in the tube section ( 6 ). An operating element ( 7 ), with a first handle grip ( 8 ), is arranged on the housing section ( 6 ) at approximately 90 degrees to the tube section ( 5 ). The tube section ( 5 ) is embodied as a second handle grip ( 9 ), thus providing ergonomic advantages on operating the hand hair dryer ( 1 ).
1. A hand hair dryer ( 1 ) comprising:
an electric fan ( 2 ) located in a housing portion ( 6 );
a first handle grip ( 8 ) comprising operator control elements ( 7 ) and connected to the housing portion ( 6 ); and
a barrel portion ( 5 ) containing an electric heater ( 3 ) and connected to the housing portion ( 6 ) at an angle of approximately 90° with respect to said first handle grip ( 8 ) wherein:
said electric heater ( 3 ) is located in line with said electric fan ( 2 ) for generating an air stream ( 4 ) from said barrel portion ( 5 );
said barrel portion ( 5 ) is embodied as a second handle grip ( 9 ) that is insulated from the heater ( 3 ) to prevent said second handle grip ( 9 ) from getting hot during use;
a single cold air combination switch ( 16 , 16 . 1 , 16 . 2 ) is located only on the housing portion ( 6 ) between said first handle grip ( 8 ) and said barrel portion ( 5 ) at the angle formed by the first handle grip ( 8 ) and the barrel portion ( 5 ); and
said cold air combination switch ( 16 , 16 . 1 , 16 . 2 ) is configured to be actuated selectively from the first or second handle grip ( 8 , 9 ), by direct contact between the cold air combination switch and one finger of a hand on either the first handle grip ( 8 ) or the second handle grip ( 9 ).
2. The hand hair dryer in accordance with claim 1 , wherein the barrel portion ( 5 ) is heat-insulated from the outside.
3. The hand hair dryer in accordance with claim 1 , wherein the second handle grip ( 9 ) and the barrel portion ( 5 ) are embodied as heat-insulated from the outside.
4. The hand hair dryer in accordance with claim 1 , wherein the second handle grip ( 9 ) is shaped cylindrically.
5. The hand hair dryer in accordance with claim 1 , wherein the first and second handle grips ( 8 , 9 ) are each provided with a nonslip surface ( 13 ).
6. The hand hair dryer in accordance with claim 1 , wherein the cold air combination switch ( 16 ) is a pushbutton ( 17 ).
7. The hand hair dryer in accordance with claim 1 , wherein the cold air combination switch ( 16 . 1 ) is a one-legged toggle switch ( 18 ).
8. The hand hair dryer in accordance with claim 1 , wherein the cold air combination switch ( 16 . 2 ) is a two-legged toggle switch ( 19 ).
9. The hand hair dryer in accordance with claim 1 , wherein:
a centrally located warm-air conduit ( 28 ) and a coaxial cold-air conduit ( 29 ) are provided in the barrel portion ( 5 );
the central warm-air conduit ( 28 ) is formed by a hollow-cylindrical barrel ( 30 ), in which the heater ( 3 ) is located;
the coaxial cold-air conduit ( 29 ) is formed by the barrel portion ( 5 ) and the hollow-cylindrical barrel ( 30 ); and
the central warm-air conduit ( 28 ) and the coaxial cold-air conduit ( 29 ) are acted upon by a cold air stream ( 31 ) of the fan ( 2 ) and, by means of the heater ( 3 ), a warm air stream outlet ( 32 ) is effected out of the central warm-air conduit ( 28 ), and a cold air stream outlet ( 33 ) is effected from the coaxial cold-air conduit ( 29 ).
10. A hand hair dryer ( 1 ) comprising:
an electric fan ( 2 ) located in a housing portion ( 6 );
a first handle grip ( 8 ) comprising operator control elements ( 7 ) and connected to the housing portion ( 6 ); and
a barrel portion ( 5 ) containing an electric heater ( 3 ) and connected to the housing portion ( 6 ) at an angle of approximately 90° with respect to said first handle grip ( 8 ) wherein:
said electric heater ( 3 ) is located in line with said electric fan ( 2 ) for generating an air stream ( 4 ) from said barrel portion ( 5 );
said barrel portion ( 5 ) is embodied as a second handle grip ( 9 );
a single cold air combination switch ( 16 , 16 . 1 , 16 . 2 ) is located only on the housing portion ( 6 ) between said first handle grip ( 8 ) and said barrel portion ( 5 ) at the angle formed by the first handle grip ( 8 ) and the barrel portion ( 5 );
said cold air combination switch ( 16 , 16 . 1 , 16 . 2 ) is configured to be actuated selectively from the first or second handle grip ( 8 , 9 ), by direct contact between the cold air combination switch and one finger of a hand on either the first handle grip ( 8 ) or the second handle grip ( 9 );
a centrally located warm-air conduit ( 28 ) and a coaxial cold-air conduit ( 29 ) are provided in the barrel portion ( 5 );
the central warm-air conduit ( 28 ) is formed by a hollow-cylindrical barrel ( 30 ), in which the heater ( 3 ) is located;
the coaxial cold-air conduit ( 29 ) is formed by the barrel portion ( 5 ) and the hollow-cylindrical barrel ( 30 ); and
the central warm-air conduit ( 28 ) and the coaxial cold-air conduit ( 29 ) are acted upon by a cold air stream ( 31 ) of the fan ( 2 ) and, by means of the heater ( 3 ), a warm air stream outlet ( 32 ) is effected out of the central warm-air conduit ( 28 ), and a cold air stream outlet ( 33 ) is effected from the coaxial cold-air conduit ( 29 ).
