Definitions
- the invention relates to an electric hair dryer with a receiving housing for a blower and a heating register, in which the receiving housing and handle are formed by interconnected, shell-shaped molded bodies and in which the receiving housing receives a sleeve-shaped middle part carrying the blower and the heating register and in Receptacle housing supply air openings and an exhaust air opening are formed, the exhaust air opening being penetrated through a section of the central part above the receiving housing.
- the invention has for its object to achieve a further calming and a uniform outlet of the exhaust air in an electric hair dryer of the latter design.
- this object is achieved in that a cup-shaped housing, which widens conically in the flow direction of the exhaust air, can be detachably plugged onto the projecting section of the central part and / or the part of the receiving housing adjacent to it, in that the bottom of the housing has a Has a large number of passage openings for the blower air and between the passage openings on the outside of the housing at a distance from each other a number of hollow pins or lugs extending axially parallel to the exhaust air flow, which have inlet openings at the end facing the housing and at the free end face and / or in the peripheral surfaces have outlet openings for exhaust air.
- the receptacle housing forms a diffuser which contributes to the further calming of the blower exhaust air, whereby the hairdryer can now be placed directly on the head of the user without causing turbulence, while the downstream interior of the housing for compensation and mixing of the exhaust air, whereby zones of different air velocities and air volumes in the exhaust air leaving the housing are omitted.
- the housing wall of the same firmly connected inner sleeve can be attached and held to the peripheral surface of a partial section of the central part in a frictionally locking manner.
- the inner sleeve gives the opportunity to design the housing with any size and shape.
- the bottom of the housing is formed by a number of integrally encompassing spacers and the free end of the housing wall. det and that the annular bodies are firmly connected to one another by webs to form passage openings for the exhaust air.
- the pins or shoulders are preferably formed in the web areas of the bottom of the housing.
- the bottom of the housing is formed by a plate part connected to the housing wall, which has a plurality of slot-shaped recesses on concentric circular lines as passage openings for the exhaust air and hollow pins or lugs with passages therebetween.
- the bottom of the housing can be curved as a flat surface or preferably concave in the direction of the fan, which results in a better adaptation of the hair dryer to the shape of the head.
- the housing wall, the inner sleeve and the base as well as the pins or lugs are expediently formed by a one-piece molded part made of a thermoplastic or thermosetting material.
- the housing parts are also manufactured separately from one another and with one another, e.g. by gluing, press fitting or the like. can be connected.
- the pins or shoulders are cylindrical or frustoconical in shape with a diameter that decreases toward the free end. It is also possible to close the free ends of the pins or shoulders and to provide the circumferential surface offset over partially long passage openings.
- the passage openings can be arranged arbitrarily offset in the circumferential surface of the pins or projections or expediently arranged at 90 ° to one another in the circumferential surface.
- the pins or lugs can optionally be designed with the same lengths and / or diameter sizes or have lengths and / or diameter sizes of different sizes. In the latter embodiment, the pins or shoulders assigned to the central region of the base can each have a shorter length.
- the housing has a radial clearance over the housing section facing the handle of the hairdryer. This enables actuators for the electrical switching elements accommodated in the handle to be handled without obstruction.
- the retraction can be arbitrary, in particular limited by a flat housing surface.
- the housing by mutually fixable wall parts which hold the bottom of the housing fixed or axially displaceable against a restoring force.
- the displaceable design of the base allows the electric hair dryer to be placed flexibly against the user's head.

- Fig. 2 shows a pin with openings for exhaust air in
- FIG. 3 shows a housing acting as a diffuser in plan view

- FIG. 1 5 a housing acting as a diffuser
- FIG. 6 a base for a housing of FIG. 5, in

- 1 and 1 ' denote housing shells, which are connected to one another at 2 and together form the receiving housing. Web areas 3 and 3 'are arranged on the housing shells 1 and 1', which result in a handle.
- the housing shell 1 has a number of supply air openings 4 for blown air, while the housing shell 1 'is provided with a single exhaust air opening 5 which extends approximately over the entire cross section.
- the two Gepuruse ⁇ chalen 1 and l 1 take on a sleeve-shaped central portion 6 which dips with a web 7 in the land areas 3, 3 '.
- a blower motor 8 with an impeller 9 and a heating register 10 are set in the middle part 6. With 11 are one
- the ring bodies 11 serve for the air alignment in the area of the exhaust air opening.
- the central part 6 extends, as can be seen in FIG. 1, with a partial section 6 'through the exhaust air opening 5 of the housing shell 1' and serves as a carrier for a pot-shaped housing 12 which acts as a diffuser.
- the housing 12 is essentially in the flow direction of the exhaust air conically widening and can be fixed with an inner sleeve 13 to the subsection 6 ', in particular frictionally, while the housing 12 with an extension 12 'over the wall section 12''of the housing shell l 1 .
- the bottom 14 of the housing 12 is preferably concave in the direction of the fan and provided with a number of passage openings 15 for the exhaust air. In the embodiment of FIG.
- the bottom 14 has a number of annular bodies 16 concentrically encompassing one another, which together with the wall section 12 ′′ of the housing 12 result in the bottom.
- the ring body 16 and the wall section 12 ′′ are connected to one another by webs 17 (FIG. 3), hollow pins 18 or projections being fixedly arranged in the regions of common webs 17 ′.
- the pins 18 are formed on the fan side with inlet openings 18 'and open at the free end through outlet openings 18'', so that they give additional passages for exhaust air. As shown in the exemplary embodiments of the figure, the pins 18 can be of the same length or of different lengths.
- the housing 12 is provided with a cutout 19 which permits unimpeded handling of actuators 20 for the switches 21 arranged on the web 7 for the blower motor and / or the heating register.
- the recess 19 is, as can be seen in FIG. 4, delimited by a flat surface 19 '.
- the housing 12 is provided with a bottom 14 which has a plurality of slots 22 to form passage openings for exhaust air. Furthermore, hollow pins 23 are provided, which are closed at the free end and have passage openings 24 in the region of their peripheral surfaces. As can be seen in FIG. 8, the passage openings 24 are each offset from one another by 90 °.
- the passage openings are slit-shaped (Fig. 7) designed and extend over a partial length of the pins 23.
- the closed free ends of the pins 23 are delimited by spherical surfaces, so that the housing 12 acting as a diffuser on the head of the user can always be positioned without injury.
- the bottom 14 of the housing 12 of FIG. 5 can be firmly connected to the wall 12 ′′. It is possible, as shown in FIGS.
- the base 14 to be axially displaceable in the housing 12 and to move it against the spring force 25 from the outer position shown into an inner end position.
- the spring force can be applied by helical springs which are clamped between the base 14 and the wall 12 ′′ offset by the same angular degrees from one another.
- the bottom 14 can be supported on the wall 12 'by an annular part 14''projecting transversely outwards and form the bearing for the helical springs.
