Abstract

The invention relates to a device ( 2 ) comprising a boiler ( 1 ) for generating steam, used for example in the steam-treatment of hair. The boiler ( 1 ), which is located in a recess ( 15 ) comprises a refill cap ( 3 ) and a steam outlet ( 4 ) in its upper region. The steam outlet ( 4 ) is situated in the upper lateral region ( 5 ) of the boiler ( 1 ). The boiler ( 1 ) is provided with an outflow opening ( 6 ) below the steam outlet ( 4 ), the lower edge ( 7 ) of the steam outlet ( 4 ) and the lower edge ( 8 ) of the outflow opening ( 6 ) defining a height (H) of a boiling chamber (W). The steam outlet ( 4 ) communicates with a steam conduit coupling ( 9 ) of a steam conduit ( 10 ) and the outflow opening ( 6 ) communicates with a sealing part ( 11 ) of the recess ( 15 ).

Claims (7)

1. A device having a boiler for generating steam, in which the boiler inserted into a receptacle has a refill cap, located at the top, and a steam outlet opening, wherein the steam outlet opening ( 4 ) is located in the upper lateral region ( 5 ) of the boiler ( 1 ); the boiler ( 1 ), below the steam outlet opening ( 4 ), is provided with an outflow opening ( 6 ), and a lower edge ( 7 ) of the steam outlet opening ( 4 ) and a lower edge ( 8 ) of the outflow opening ( 6 ) form a height (H) of a boiling space (W), and the steam outlet opening ( 4 ) corresponds to a steam conduit coupling ( 9 ) of a steam conduit ( 10 ), and the outflow opening ( 6 ) corresponds to a closure part ( 11 ) of the receptacle ( 15 ) and wherein the closure part ( 11 ) is formed by an inner wall ( 16 ) of the receptacle ( 15 ).

2. A device having a boiler for generating steam, in which the boiler inserted into a receptacle has a refill cap, located at the top, and a steam outlet opening, wherein the steam outlet opening ( 4 . 1 ) is located in the upper lateral region ( 5 ) of the boiler ( 1 . 1 ); the steam outlet opening ( 4 . 1 ) is enlarged toward the bottom with a depth (T), and the enlarged part (V) of the steam outlet opening ( 4 . 1 ) forms an outflow opening ( 6 . 1 ), and the depth (T) forms a height (H) of a boiling space (W), and a height point (HP) of the height (H) is predetermined by a lower edge ( 18 ) of a steam conduit inlet ( 17 ) of the steam conduit ( 10 ); the steam outlet opening ( 4 . 1 ) corresponds with a steam conduit coupling ( 9 . 1 ) of a steam conduit ( 10 ), and below the steam conduit inlet ( 17 ), a region ( 12 ) of an inner wall ( 16 ) of the receptacle ( 15 ) closes the outflow opening ( 6 . 1 ).

3. The device in accordance with claim 1 or 2 , wherein the steam conduit coupling ( 9 , 9 . 1 ) is provided with a seal ( 13 , 13 . 1 , 13 . 2 ).

4. The device in accordance with claim 2 , wherein the steam outlet opening ( 4 . 1 ) and the outflow opening ( 6 . 1 ) together have a shape of an upright ellipse ( 19 ).

5. The device in accordance with claim 1 or 2 , wherein as the device ( 2 ), a steam treatment device ( 14 ) is provided.

6. The device in accordance with claim 5 , wherein the steam treatment device ( 14 ) is provided with a steam hood ( 31 ) for a steam treatment of hair.
