Definitions

  • the invention relates to an electric hairdryer with a handle housing housing for a blower motor and a fan wheel and a heating coil made of resistance wire, the handle has a switching element for the operating stages and off for the blower motor and heating coil.
  • the receptacle housing is formed by two pot-shaped shells connected to one another by means of clamping means, with passage openings for the blower air and one grip shell formed in the edge region of the open sides of the shells, in that the shells and grip shells with the edge surfaces of the open sides one on top of the other can be placed and enclose between them a cylindrical central part with a web extending into the grip shells and which the central part carries the blower motor with impeller and the heating winding by means of a discharge grille firmly connected to this.
  • This enables the receptacle housing to be made extremely short and a heating winding with an annular cross section to be used outside the motor profile.
  • the cross-sectional size of the heating coil gives the option of using slow-running impellers that produce a low-pressure air flow that strikes the user's hair with low pressure.
  • the prerequisite is given for simply designing different receptacle housings by means of different shells, each of which is suitable for accommodating the same cylindrical middle part with a blower motor, blower wheel and heating winding. This allows electric hair dryers of different designs to be designed while maintaining the same technical content.
  • the outlet grille is formed by a number of cylinders concentrically spaced apart and connected to one another by webs.
  • the cylinders have a directional effect on the fan air flow.
  • the cylindrical middle part is provided with the outlet grille through a recess in the front grab the side shell and let the shell protrude forward with a partial length. In this way, the shell and the middle part are supported against each other, which means that the receiving housing can be stabilized.
  • the web of the middle part receives the switching element for the operating stages and off, the actuating element of which is expediently led out of the rear grip shell via an opening.
  • the hair dryer it is provided for the connection of the shells that at least one hook part, which undercuts an undercut of the other cup-shaped shell, is formed on one of the cup-shaped bowls, and that both bowls can be detachably fixed to one another by the hook part and by additional screw connections arranged in the area of the grip plates.
  • at least one shell in the inner surface has centering pins protruding beyond the common parting plane for the respective other shell.
  • the rear shell has a blower air inlet opening that extends approximately over the entire cross section thereof and that this blower air inlet opening is overlapped by an air inlet grille formed on the shell.
  • the air inlet grille is preferably formed by transverse and longitudinal bars which are integrally formed with one another.
  • the handle scales are arranged obliquely at obtuse angles on the pot-shaped shells. There is thus the possibility of the one formed by the two handle shells Hold the handle at an angle downwards at the front by the user's hand, while the housing part accommodating the blower assumes a vertical position.
  • 1 and 2 are cup-shaped shells, which form the receiving housing for a cylindrical middle part 3, which in the exemplary embodiment accommodates the fan motor 4 with fan wheel 5 and a heating winding 6.
  • the edge region of the shells 1 and 2 is followed by obtuse downward and forward grip shells 7, 8, which together hold a shaped piece 9 with an eyelet 10 and a cable entry 11.
  • the shells 1, 2 and the grip shells 7, 8 are formed in the exemplary embodiment from plastic, which have a groove 12 or tongue 13 in the region of their common parting plane.
  • a hook part 14 is formed on the shell 1 and engages in a recess 15 in the shell 2 when the housing parts 2 are joined together.
  • the grip shell 7 has support lugs 16 which serve to receive threaded screws (not shown) which can be introduced into recesses 17 in the grip shell 8.
  • the front shell 1 is further provided with an opening 18 which is penetrated through the front end of the middle part 3 when the hair dryer is being assembled. Furthermore, the rear shell 2 has a supply air opening 19 over which an air inlet grille 20 (FIG. 3) formed by webs 20 'and 20' extends.
  • the air inlet grille 20 is made in one piece with the shell 2. 21 means centering pins, while 22 support lugs form for the middle part 3.
  • the central part 3 as shown in FIGS. 2 and 6 in particular, has at the air outlet end a number of cylinders 23 which are coaxially spaced from one another and are connected to one another by webs 24.
  • the blow-out grille formed by the cylinders 23 and webs 24 carries the blower motor 4 with its blower wheel 5 and the heating winding support 25.
  • the blower motor 4 is designed as a slow-running blower motor, as a result of which a low-impact, smooth exhaust air flow leaves the blow-out grille 23, 24.
  • a web 26 is arranged in which the switching element 27 for the blower motor and heating winding is accommodated.
  • the switching element 27 is adjustable by an actuating element 28, which can be detected via a recess 29 in the grip shell 8, in the operating stages or off.
