Definitions

  • the invention relates to a diffuser, in particular for electric hair dryers with a housing receiving a blower and a heating register and a funnel-shaped diffuser housing which can be attached to the hair dryer housing and which or the like by means of an annular body.
  • a wall provided with air passage openings, which firmly supports lugs or pins serving as spacers on the outside.
  • the blower air in electric hair dryers with high flow velocity leaves the mostly nozzle-shaped outlet opening of the hair dryer housing, so that when the hair dryer is used, swirling of the hair is unavoidable.
  • it is known to reduce the flow speed of the blower air by placing a diffuser at the entry opening of the hairdryer housing, the end of the diffuser facing away from the blower being formed by a wall which is fixedly connected to the diffuser housing and has a number of outlet openings for the blower air.
  • this object is achieved in that the air outlet end of the diffuser housing is open, that in the diffuser housing opening a freely movable closure body between two axial end positions is set for the diffuser housing opening and that the closure body counter to a restoring force from the outer end position towards the inner end position in the Diffuser housing can be inserted and / or swung in on all sides.
  • the resilient, elastically flexible arrangement of the closure body in this way results in an overstroke for the closure body when the restoring force is exceeded by a pressing force, which prevents injuries to the head surface. Due to the flexibility of the closure body, there is no metering of the pressing force, and by means of the flexibility of the closure body an automatic spring pressure force regulation can be effected.
  • the closure body is designed to be flat.
  • the closure body in any other way, e.g. from the central axis to the edge region in the direction of flow of the blower air and curved outward in the shape of an arc.
  • the curved design gives advantages by adapting to the shape of the user's head.
  • the closure body can be held anywhere in the diffuser housing.
  • the closure body with a flared edge strip can be placed and held on the boundary surface of the diffuser housing opening by the restoring force, the arrangement of a cranked edge strip on the closure body, which covers a bent edge strip of the diffuser housing opening, having proven to be advantageous.
  • the closure body in another way e.g. to be supported by means of bends, projections or gates provided in the edge area on the edge strip of the diffuser housing opening.
  • the restoring force acting on the closure body can be applied by a number of spring elements clamped on a circular line at a distance from one another between the closure body and the diffuser housing.
  • Helical springs can advantageously serve as spring elements. It is also envisaged to apply the restoring force by means of a single annular spring element which is inserted between the closure body and the diffuser housing. Decisive for the design of the spring elements is the creation of the prerequisite for pivoting in all directions and an axial displacement of the closure body. Furthermore, it is provided to use spring elements with a linear bias against the fan flow or with a progressive bias.
  • the pins arranged as spacers on the closure body are designed as solid bodies and that the closure body has air passage openings between the pins.
  • the pins serving as spacers are formed by hollow bodies, the interior spaces of which are connected to the interior of the diffuser housing and which, for example, have outlet openings for the blower air at the outer end.
  • the pins serving as spacers are formed by hollow bodies which are closed on the end faces and whose interior spaces are in connection with the interior of the diffuser housing and with outside air openings arranged in the peripheral surface. It goes without saying that the pins can of course also have air passage openings at the free ends and in the peripheral surface. Furthermore, in a further development of the diffuser, provision is made for the pins serving as spacers to be of the same or different lengths. By choosing different lengths of pen, the diffuser is further adapted to the shape of the user's head. Furthermore, it is also provided that the diffuser housing and the ring body serving to hold it are formed by molded bodies made of a thermoplastic or thermosetting material.
  • the diffuser housing and the ring body are expediently created by a common molded body made of a thermoplastic or thermosetting material. It has also proven to be advantageous if the closure body is formed by a molded part made of a flexible or resiliently elastic material, in particular a plastic or rubber material.
  • 1 denotes an electric hair dryer known per se
  • the housing 1 'of which, in a manner known per se, has a blower and a heating register (not shown) and switching means 2 for these.
  • an outlet connection for the blower exhaust air is designated, on which a diffuser 4 is attached.
  • the diffuser 4 can be fixed in another way, for example by means of a bayonet connection to the hairdryer housing 1' End provided with a ring body 4 '".
  • the diffuser housing is provided with a housing opening 5, into which an arched closure body 6 is inserted.
  • the closure body 6 is supported with a cranked edge strip 7 on a retracted edge strip 8 of the diffuser housing 4 'and held by spring elements 9.
  • the spring elements 9 are formed by a number of helical springs offset from one another by predetermined angular degrees. Under the influence of a compressive force acting against the blower flow on the closure body 6, for example when using the hair dryer, the closure body can be pushed into the diffuser housing or pivoted in on all sides.
  • a spring ring 9 " as shown in FIGS. 6 and 7, can also be used to support the closure body 6.
  • the closure body 6 is formed with a number of pins 10 which are offset from one another on a plurality of circular lines and which serve to determine the distance between the diffuser 4 and the head surface of the user.
  • the pins 10 are designed as solid bodies, in the embodiments of FIGS. 2 and 3, the pins 10 are designed as hollow bodies and air passage openings 11 are provided in the area of their circumferential surface and are connected to the interior spaces 13.
  • the closure body 6 between the pins 10 has air outlet openings 12, whereby an unobstructed blower air outlet via the openings 11, 12 is made possible.
  • FIG. 5 shows how, when the closure body 6 is subjected to a one-sided load, the closure body 6 can be pivoted into the diffuser housing 4 'by pressing the helical springs there more firmly.
