Definitions

the invention relates to a hair treatment device with an infrared radiator element and a blower for heating and drying human hair.
Hair treatment devices with an infrared radiator element and with a plurality of infrared radiator elements which have a blower are known.
the infrared radiator elements serve to radiate infrared radiation onto the hair in order to heat it.
the heat causes a drying process or a chemical reaction, e.g. a permanent waving of the hair accelerates.
the blower creates an air flow that shortens the drying time of the hair.
the flowing air is guided past an infrared radiator element in known devices such that the waste heat of the infrared radiator element heats the blower air.
the object is to improve a hair treatment device with an infrared radiator element and a blower such that the blower air is sufficiently heated by infrared radiation without the radiation power of the infrared radiator element being reduced.
a flow channel is provided in the infrared radiator element and the fan is arranged in such a way that the air moved by the fan flows at least partially through the flow channel.
the flow channel is provided in the infrared radiator element.
the limits of the flow channel are relatively hot when the infrared radiator element is switched on.
the flow channel is surrounded by these hot boundaries along the entire length of the channel.
the blown air flowing through the flow channel is thus heated to a relatively great extent.
the temperature of the blown air on the hair will soon also be at a constant value, since the path of the blown air always remains the same, i.e. the hair treatment device emits a stable radiation output shortly after being switched on, and the radiator element heats up to a constant temperature.
a cooling of an infrared radiator element due to convection by the blower air is prevented according to the invention, so that the infrared radiator element can always emit the same radiation power.
the infrared radiator element has a reflector comprising an infrared radiator source (claim 2)
the radiation power of the infrared radiator source is improved in the desired direction.
the flow channel can run between the housing of the infrared radiator element and the reflector (claim 3). With such a course, the flow channel is heated very well since the reflector and the housing become very hot during operation. The flow of the blower air through the flow channel cools down the housing and the reflector and thus improves the device safety with regard to touching these parts, without the need for additional technical effort. In addition, the susceptibility to failure of components integrated in the infrared radiator element is extended.
the air flowing into the flow channel is already preheated by an infrared radiator source when a suction point of the flow channel lies on the side of the infrared radiator element that emits infrared radiation (claim 4). At least partially is a recirculation mode, which leads to a higher temperature of the blown air.
the fan air becomes particularly warm when it is heated along a relatively long path and its flow speed is relatively low in this way. Good heating is also achieved if the infrared emitter source is rod-shaped and the flow channel is tangential to the infrared emitter source (claim 5). This results in a further improvement with regard to the blower temperature reached if, according to a further development, there is a suction point between the housing and a radiation-side end of a reflector, and a suction point of the flow channel lies between the housing and another radiation-side end of a reflector (claim 6).
a suction point can be designed, for example, as a narrow slot that runs parallel to an infrared radiation source.
a reflector preferably has at least one air passage, which is an outlet point of the flow channel (claim 7).
the air heated in the flow channel can flow out of the infrared radiator element relatively centrally.
the air released can then be directed past the infrared radiation sources so that they do not cool down.
heat can be supplied to both sides of two reflectors from a central or relatively central outlet point if two infrared radiator sources are provided, each with one reflector in an infrared radiator element, and part of the flow channel runs between the two reflectors (claim 8).
a further heating of the air in the flow channel is achieved by means of reflector cooling plates around which air flows (claim 9).
the reflector cooling plates can be provided with cooling fins.
a particularly compact design of the hair treatment device is provided if the fan is arranged in the flow channel of the infrared radiator element (claim 10). The blower air is then sucked into the infrared radiator element at a suction point of the infrared radiator element and fed through the flow channel to the outlet point.
a centrically blow-out blower air can be achieved by means of an outlet point of relatively large cross-section if a single outlet point of the flow channel is provided in the center of a round infrared radiator element and the outlet point is covered by a protective grille (claim 11).
the suction point can be a circularly curved slot on the circumference of the round infrared radiating element.
the protective grille protects against access to the blower. If the temperature of the blower air is not sufficient for a specific application, additional heating in the flow duct (claim 12) can ensure a higher blower air temperature. This additional heating can be switched on and off (claim 13).
infrared radiator elements In order to achieve sufficient heating of all hair areas, several infrared radiator elements should be provided on one hair treatment device (claim 14). It is not generally necessary to equip all infrared radiator elements with a blower. It is sufficient e.g. for many applications also to design only one of the infrared radiator elements according to the invention.
a protective grille (claim 15).
An infrared radiator element 1 contains a reflector 3 in a housing 2, which surrounds two infrared radiator sources 5 designed as infrared tubes 4 (FIG. 1, FIG. 2).
the reflector 3 is open on one side 6, so that the infrared radiation is radiated in this direction on hair to be dried.
air 9 (represented by arrows) is drawn in at a suction point 10 and blown out of an outlet point 11.
the air warms up on its way along the relatively warm components, reflector 3 and housing 3.
the warm air 9 is blown onto human hair that is to be dried.
the suction point 10 is located on the side 6 of the infrared radiator element 1, on which the infrared radiation is emitted and thereby sucks in relatively warm ambient air.
the infrared radiator source 5 is rod-shaped and the flow channel 7 extends tangentially to the infrared radiator source 5.
the reflector 3 in FIGS. 3 and 4 has air outlets 12 as outlet points 11 and an impeller 13 as blowers 8.
the infrared radiator element 1 has a suction point at the top and bottom 10. In comparison to the exemplary embodiment in FIGS. 1 and 2, the outlet points 11 are arranged more towards the center, ie closer to the infrared radiator source 5. As a result, the air 9 heated in the flow channel 7 is additionally heated by the infrared radiation emitted to the side 6.
the suction points 10 lie between the housing 2 and in each case one end 14, 15 of a reflector 3a, 3b on the radiation side.
the two reflectors 3a, 3b each surround an infrared radiator source 5.
a part 7a of the flow channel 7 runs between the two reflectors 3a, 3b.
both the suction point 10 of the flow channel 7 and the outlet point 11 are covered with a protective grid 16.
the flow channel 7 is delimited here on the one hand by the reflectors 3 and on the other hand by a guide plate 17.
the fan 8 is inserted into the flow channel 7.
an insert 18 for flow guidance is inserted in the flow channel 7 on the blower 8.
the blower 8 is arranged in the center of a round infrared radiator element 1.
a single central outlet point 11 of the flow channel 7 is provided.
the outlet point 11 is covered by a protective grille 16.
the infrared radiator sources 5 are bent and connected to supply lines 19 (FIG. 10).
