Definitions

  • the invention relates to an air-flowable additional part which is attached to a hair dryer, or an independently manageable additional part for a hair dryer according to the preamble of claims 1 or 2.
  • stationary nozzles are generally known, which are either connected in one piece to the hair dryer housing or can be plugged or clipped onto this as an independently manageable additional part.
  • These known nozzles for hair dryers are either only suitable for bundling or for expanding the air flow emerging from the hair dryer.
  • a dynamic influencing of the exiting air flow - for example in the form of pulse-like, temporal and / or spatial air flow variations - is not possible with the known nozzles.
  • the invention has for its object an additional part for a hair dryer for dynamic temporal bwz. to further develop spatial changes in the emerging air flow in such a way that further moving or rotating parts can be dispensed with. It should also be possible to vary the temperature of the escaping air flow with the additional part, which can be placed on and removed from the hair dryer in particular as an independently manageable part, so that two different temperature levels of the escaping one and the same heating level of the hair dryer Air flow are made possible by attaching or removing the additional part.
  • an additional part with the features of claim 1 or claim 2.
  • the additional part is designed as a nozzle and the fastening means allow rotation of the nozzle with respect to the hair dryer, the nozzle having air guide means which, in cooperation with the air flow emerging from the hairdryer and flowing through the nozzle, exert a torque on the nozzle, Nozzle for bundling or expanding the air flow exiting the hair dryer is also advantageously used to vary the exiting air flow in the form of dynamic changes in time or space, which promotes particularly rapid drying of the hair.
  • the additional part is used as an independently manageable part, it is also advantageously designed as a nozzle, the nozzle having air guide means which, in cooperation with the air flow emerging from the hairdryer and flowing through the nozzle, exert a torque on the nozzle.
  • air guide means are provided on the nozzle means that the air flow flowing through them allows them to rotate easily, so that the emerging air flow is not only bundled or expanded spatially, but can also be varied over time.
  • the warm air flow exiting the hair dryer is mixed with the surrounding cold air, which overall leads to a reduction in the temperature of the air flow.
  • the number of available temperature levels of the hair dryer can be additionally varied by plugging in or removing the nozzle.
  • the fastening means are designed as an axle and associated receiving bearing.
  • the fastening means of the nozzle or the hair dryer are advantageously assigned. This provides a structurally simple solution for a nozzle, regardless of whether it is removable or permanently connected to the hair dryer.
  • the air guiding means are formed by air guiding elements arranged on the inner wall of the nozzle or by an asymmetrical shape of the nozzle.
  • the air guiding elements can, for example, be of helical design in order to generate a corresponding torque acting on the nozzle when the air flow impinges on the air guiding elements.
  • An alternative embodiment is to design the outlet opening of the nozzle asymmetrically with respect to the longitudinal edges, for example to provide offset recesses or the like, in order to generate a torque of approximately diametrically opposite regions of the outlet opening by a correspondingly reduced flow resistance.
  • the nozzle has two or more channel-like openings enables in particular spatial variation of the air flow, for example a fanning out of the air flow in the form of a conical jacket. This favors the drying process of the hair.
  • the air guiding means is also advantageous to design the air guiding means as one or more channels, the channels being arranged eccentrically and inclined with respect to an axis of rotation of the nozzle.
  • the nozzle 1 is shown in perspective.
  • the hair dryer 2 and the nozzle 1 are drawn here in a disassembled position.
  • the axis 3 of the nozzle 1 is provided at its free end with a slit or a gap 4 and has a spherical shape 5.
  • the axis 3 can be mounted in the receiving bearing 6 of the protective grid 7 of the hair dryer 2, so that the nozzle 1 can rotate in this bearing 6.
  • the receiving bearing 6 is preferably located in the longitudinal axis of the fan motor shaft of the hair dryer 2.
  • the nozzle 1 has a narrow air outlet opening 8 and concave surfaces 9.
  • the course of the longitudinal edges 10 shows asymmetrically designed recesses 10a.
  • the axis 3 of the nozzle 1 is placed in the middle of the support beam 12 (FIG. 5), which is attached to the round base edge 13 which is adapted to the contours of the blow-out opening of the hair dryer 2.
  • FIG. 1 shows straight longitudinal edges 10 of the air outlet opening 8.
  • FIG. 2 shows straight longitudinal edges 10 of the air outlet opening 8. However, they are designed in such a way that they show a reverse slope in side view (FIG. 3).
  • the dashed line marks the obstructed course of one longitudinal edge 10.
  • the stop edge 14 of the axis 3 can also be seen in FIG. 3. Your task is not to let the base edge 13 come into contact with the hair dryer during the rotation of the nozzle 1.
  • FIG. 4 shows the embodiment of the nozzle shown in perspective in FIG. 1 in a schematic side view.
  • the longitudinal edges 10 of the surfaces 9 of the air outlet opening 8 here show an asymmetrical arrangement of the cutouts 10a.
  • the course of the one recess 10a, which is blocked from view, is indicated by a broken line.
  • FIG. 5 shows the nozzle 1 in the direction of view towards the base edge 13.
  • the air outlet opening 8 with the asymmetrically arranged recesses 10a can be clearly seen here.
  • the position of the support beam 12 with the axis 3 also reflects the design features of the pulse nozzle.
  • the surfaces 9 of the air outlet opening 8 act like a rotating propeller, so that air is laterally sucked in at room temperature and conveyed further in the blowing direction. This process causes the special cooling effect of the nozzle 1.
  • FIG. 6 shows a further exemplary embodiment of a nozzle 1, in which the nozzle has two channel-like openings.
  • the openings are formed by channels 16, 17 which are arranged eccentrically and inclined with respect to the axis of rotation 15 of the nozzle 1.
  • the means for mounting or attaching the nozzle 1 to the hair dryer 2 are not shown in the drawing, but essentially correspond to those of the previous description or figures.
  • this nozzle When the hair dryer is switched on, this nozzle generates a rotating air flow consisting of one or more individual jets that circulate on a cone jacket.
  • the rotational speed of the nozzle 1 or a bundling or scattering of the air flow can be set.
