Patent number: 6701937Abstract: Steam styling tongs including an evaporating device which is supplied with heat by a heating device and comprises an evaporator surface in thermal contact with the heating device. Liquid evaporates on the evaporator surface into steam, which then passes into a steam-distributor chamber and, there, flows outward via through-passages. The heating device is formed in a combustion chamber of the drum, in which, during the heating operation, flame-free combustion of a gas takes place by means of a catalyst, of which the combustion gases pass out via outlets formed in the drum or in the combustion chamber. The combustion chamber and the steam-distributor chamber are formed by a common chamber. Means which prevent water from penetrating into the common chamber are also provided.Type: GrantFiled: September 9, 2002Date of Patent: March 9, 2004Assignee: Braun GmbHInventors: Peter Janouch, Peter Lange, Dieter Liebenthal, Silvia Rix, Heinz Kern, Peter Ruppert, Friedrich Henninger, Jürgen Seng

Publication number: 20030037795Abstract: The curling tongs (1) comprise a heating device (17), which is arranged in a tubular heating rod (25) and extends in the longitudinal direction of the heating rod (25). The curling tongs (1) further comprise a fuel container, for receiving and discharging liquid fuel, and a valve device (5), which serves for gasifying and regulating the fuel. The heating device (17) is controlled in dependence on temperature by a thermostat (6) adjacent to it. According to the invention, the thermostat is shielded thermally from the heating device (17) by a partition wall (49). As a result, the temperature behavior of the heating rod is better regulated, with excessively high temperature peaks being avoided.Type: ApplicationFiled: September 9, 2002Publication date: February 27, 2003Inventors: Peter Janouch, Peter Lange, Dieter Liebenthal, Silvia Rix, Heinz Kern, Peter Ruppert, Friedrich Henniger, Jurgen Seng

Publication number: 20030037796Abstract: The invention relates to a hair-shaping appliance (1), in particular steam styling tongs, having a tubular drum (3) which treats the hair and is provided with through-passages (2). Projecting out of the drum (3) is a dosing device (26), upon the actuation of which liquid passes out of an outlet (18) of a liquid container (19) via a liquid-channeling device (17). Formed in the drum (3) is an evaporating device (13) which is supplied with heat by a heating device (12) and comprises an evaporator surface (16) which is in thermal contact with the heating device (12). Liquid which has passed out evaporates on the evaporator surface into steam, which then passes into the steam-distributor chamber (91) and, there, flows outward via the through-passages (2).Type: ApplicationFiled: September 9, 2002Publication date: February 27, 2003Inventors: Peter Janouch, Peter Lange, Dieter Liebenthal, Silvia Rix, Heinz Kern, Peter Ruppert, Friedrich Henniger, Jurgen Seng

Publication number: 20030029854Abstract: The invention relates to a hair-styling appliance (1), in particular steam styling tongs, which has a tubular drum (3) which treats the hair, is provided with through-passages (2) and in which a heating device (12) and a dosing device (26) are formed. Upon actuation of the dosing device (26), liquid passes out of an outlet (18) of a liquid container (19) via a wick (17). An evaporating device (13) which is supplied with heat by the heating device (12) evaporates the liquid into steam, which then flows out at the through-passages (2) formed on the drum (3). The invention provides means (60, 19) by means of which, as a result of the actuation of the dosing device (26), excess liquid which may be present in the evaporator chamber (14), before the next actuation of the dosing device (26) in each case, is removed from the evaporator chamber (14) again and moved back into the liquid container (19). This arrangement only evaporates as much liquid as is desired by a user.Type: ApplicationFiled: September 9, 2002Publication date: February 13, 2003Inventors: Peter Janouch, Peter Lange, Dieter Liebenthal, Silvia Rix, Heinz Kern, Peter Ruppert, Frederich Henniger, Jurgen Seng
