Abstract: A device (1.1) for the radiation of scalp hair (2) using infrared radiation (10.3), wherein the infrared radiation (10.3) is generated by at least one linear-shaped infrared lamp (3.1) with a reflector system (4). In a first exemplary embodiment, a first reflector (6.1) is allocated to the infrared lamp (3.1) on the longitudinal side, wherein the infrared lamp (3.1) basically forms an optical collection line of the first reflector (6.1). The first reflector (6.1) with a first reflection side (9.1) and a second reflector (6.2) with a second reflection side (9.2) are placed facing each other, wherein the infrared lamp (3.1) is enclosed by the first and the second reflector (6.1, 6.2), by at least 360° altogether.

Abstract: Device (1) for the heat treatment of scalp hair (2) of a person (3), consisting of one first and one second heat radiator (11, 12), which are formed and arranged facing each other as a left side radiator (4) and as a right side radiator (5) to provide heat (6) to the side scalp hair (7), wherein the left side radiator (4) has one first ring-shaped infrared radiator (21) with one first shell ring reflector (22) and the right side radiator (5) has one second ring-shaped infrared radiator (21.1) with one second shell ring reflector (22.

Abstract: The invention relates to a power supply independent device (1) producing a hot air flow (2). Heat (4) is produced by a catalytic heating element (5) which is energized by a liquid fuel, the hot air flow (2) being produced by an electric fan (7). The inventive device (1) is provided with a fuel cell (8) which supplies electric power to the fan (7). Said device comprises a tank (10) for the liquid fuel connected with the aid of a valve (11) to the fuel cell (8) and the heating element (5) in such a way that they are jointly supplied with the liquid fuel (6).

Abstract: The electric haircutting machine includes an electrical drive motor, cutting blades driven by the drive motor, a device (22) for oiling the cutting blades and a device (20) for detecting an oil deficiency of the oil lubricating the cutting blades. The device (22) for oiling the cutting blades is connected with and responsive to the device (20) for detecting the oil deficiency, whereby the device for oiling the cutting blades is automatically activated to oil the cutting blades when the oil deficiency is detected. The device for detecting the oil deficiency detects whether or not motor current consumption, cutting blade vibration noise, haircutting machine sound level, cutting blade temperature, force acting on one of the cutting blades or drive motor rotation speed exceeds a corresponding predetermined threshold or not in order to establish the presence or absence of the oil deficiency.

Abstract: The method for detecting an oil deficiency of oil lubricating a driven cutting blade of a haircutting machine includes measuring either drive motor current consumption, cutting blade vibration noise, haircutting machine sound level, cutting blade temperature, a force acting on one of the cutting blades or drive motor rotation speed and determining whether or not the oil deficiency has occurred from a change of the chosen measured variable from a standard value occurring during normal operation without the oil deficiency. The electrical haircutting machine includes an electric drive motor, cutting blades driven by the drive motor and a device (20) for detecting the oil deficiency which advantageously includes a device for measuring one of the above-mentioned measurement variables and also a comparator for comparing the measured variable with a predetermined temperature-dependent threshold value to determine whether the oil deficiency has occurred or not.
