Abstract: An electric hair trimmer, in particular an electric razor, features a hair trimmer that includes at least one shaving system having an outer cutter and an undercutter, said cutters cooperating in order to cut off hairs. The outer cutter has at least one inner surface that is adjacent to the undercutter, at least one outer surface provided for contact with the skin, and at least one lateral surface that extends between the contours of the inner surface and the outer surface. The lateral surface and the outer surface of the outer cutter define an at least partially acute-angled first edge.

Abstract: The invention is directed to an electrically powered appliance for the treatment of hair, in particular a hair dryer, having a fan motor for generating a current of air and a heater unit for heating the air current, and a housing with an air inlet port and an air outlet port as well as a connector element, for connecting the hair dryer to an implement for hair treatment. This implement is equipped, particularly for the styling and/or drying of hair, with an electrical load, for example, an electric motor, and is attachable to the air outlet port of the hair dryer. The connector element includes at least one terminal device for electrical connection to a voltage-carrying component in the hair dryer. The terminal device electrically at selected locations is connected with the heater unit and is disposed essentially outside the heater unit.

Abstract: An electrical heating unit, particularly for a hair drier, comprises a first wire heating element, in particular a spiral coil wire heating element (2) having a heat conductor support comprising at least one support plate (4, 5, 6), and a heat conductor winding (7) arranged thereon. This spiral coil wire heating element serves to heat the stream of air flowing through the hair drier. At least one second wire heating element is provided, serving the function of adapting the electrical voltage for a further electrical load, particularly as a series resistor, for a direct-current motor fitted with an impeller to produce the stream of air. The second wire heating element (3) comprises a frame-type heat conductor support (8) and a heat conductor winding (9) arranged thereon which fills the free area of cross section of the heat conductor support (8). Further, the second heating element (3) is secured to the first heating element (2).

Abstract: The invention is directed to an electrically powered device for the treatment of hair, in particular for the styling and/or drying of hair. This device is equipped with a first adapter element, for example, a plug-and-socket element, for connecting, in particular electrically, the device with an additional electrically powered device for the treatment of hair, which includes a second adapter element. In this arrangement, the first and second adapter elements include differentiating elements, in particular geometrical differentiating features, which are designed such that exclusively two devices equipped with corresponding differentiating elements are connectable with each other. The two connectable devices may be a hair dryer and an additional implement for a hair dryer, for example.

Abstract: The invention is directed to a filter device (10) and to a method of cleaning such a filter device for an electrically powered air-moving hair-care appliance, in particular for a hair dryer, a hot-air curling brush or the like, with a filter element (12) having an inner and an outer side (25, 26), in which the inner side (25) of the filter element (12) is arranged in the area of an air entrance opening of the appliance. The filter element (12) is configured as a type of fabric, perforated foil or the like of small thickness, comprising in particular a screening fabric made of a plastic material.

Abstract: The invention is directed to a hand-held hair dryer including a housing (10) which is comprised of a handle (12) and an air-moving outer tube (14); the outer tube (14) possesses an inlet port (16) and an outlet port (18) for an air stream, and the housing accommodates a heater and a fan generating and heating the air stream. Arranged in the outer tube (14) is an inner tube (42) receiving at least the heater. In this arrangement, the inner tube (42) is manufactured from a material having a higher thermal stability than the outer tube, and the inner tube (42) terminates flush with at least the outlet port of the outer tube (14) or projects beyond the outlet port of the outer tube (14) in the direction of flow (64). A hair styling implement as, for example, a nozzle (44), a diffuser or the like, is attachable to the inner tube (42).
