Definitions

  • the invention relates to a device for holding and centering the motor-blower unit of a fan, preferably a hand hair dryer.
  • a hand-held hair dryer with a fan wheel surrounding a universal motor and a heating register arranged in the air duct is known (FR-A-772.817), in which the housing of the blower motor with its rear bearing plate, together with the bent ends of the frame-shaped housing parts which have the brush holders are arranged on a disc, which in turn is clamped between two housing halves screwed together via a rubber profile.
  • This known mounting of the motor-blower unit has the essential disadvantage that the motor must be matched to the hand-hair dryer together with the disk, and this motor-blower unit must also be assembled with the aid of screws, which is comparatively time-consuming.
  • the present invention has for its object to form the motor-blower unit, together with the heating unit, as a unit, the assembly of this unit on the unit housing should be possible without the aid of tools.
  • the housing of the motor is at least partially encompassed by a carrier plate, the holding arms of which extend on both sides of the motor are extended beyond the rear end shield of the motor, the holding arms with their free ends in slots, grooves or strips , which are provided in or on the housing wall of the housing shell, are anchored and a support plate is inserted between the rear bearing plate of the motor and the housing shell equipped with slots, grooves or strips, which holds the cylindrical, the motor surrounding heating unit.
  • the carrier plate rests on the front bearing plate of the motor, the arms extending on both sides of the approximately cylindrical motor housing holding the motor on the unit housing wall, for which purpose the motor in the area of the anchoring points with its rear bearing plate over the carrier plate on the unit housing wall supports.
  • the carrier plate holding the cylindrical heating unit is advantageously designed as a printed circuit board which is provided with some of the electronic components required for regulating and controlling the motor and the heating unit.
  • the carrier plate is designed as a spring plate in its central part, which is supported on the front end shield of the motor.
  • the hand hair dryer consists essentially of the electronic components 2 arranged in the handle part 1, which are arranged on a circuit board 3, the actuators 4, 5 mounted and guided in the handle, the motor-blower unit surrounding the motor 7, the heater 14 and the air wheel 8 6, the air guiding duct 9 and the two air guiding flaps 10 arranged in the air guiding duct 9 with a blowout grille 11.
  • the motor-blower unit 6 In addition to the cup-shaped fan wheel 8 with its fan blades 12, the motor 7, the carrier plate 13 and the cylindrical heating unit 14, the motor-blower unit 6 also has a circular disc-shaped carrier plate 15 with some electronic components 16 fastened to it and finally a bowl-shaped air baffle 17, which is arranged between the motor 7 and the heating unit 14.
  • the support plate 13 encompassing the motor is supported with its central part 18 on the front bearing plate 19 of the motor 7 and pulls the motor together with the support plate 15 against the assembly housing wall 20 (FIG. 1), on which the support plate 13 is located on both sides of the Motor housing extending arms 21, 21 a is anchored.
  • the motor 7 and the carrier plate 15 are first soldered to one another by inserting the connecting lugs 27, 28 (FIG. 3) of the motor 7 through openings in the carrier plate 15.
  • the carrier plate 15 is designed as a printed circuit board (the conductor tracks are not shown in more detail), the connecting tabs 27, 28 are directly in the region of the passage through the Soldered openings.
  • the cup-shaped air baffle 17 is arranged on the carrier plate 15 with the aid of the fastening fingers 29, 30 (FIG. 3).
  • the heating unit 14, which is designed as a meandering heater, can be soldered to the carrier plate via the contact tabs 31, 32, 33 (FIGS. 3 and 2). Before the fan wheel 8 is fastened to the shaft 34 of the motor 7 (FIG.
  • the U-shaped support plate 13 is pushed over the motor 7 (in the direction of arrow A), the ends of the arms 21, 21 a of the carrier plate 13 hold the carrier plate 15 on the unit housing wall 20 (FIG. 4), and the hooks 23, 24 behind strips 35, which are parts of the housing shell 36 of the hand hair dryer housing, grasp.
  • the carrier plate 13 is made of sheet steel (i.e. from a resilient material), and in the area of the front bearing plate 19, in its central part 18, it is designed as a spring plate, the motor-blower unit is pulled so firmly against the inner surface 20 of the housing shell 36 that on the one hand there is a vibration-free and reliable connection of the part 6 to the housing shell 36 and on the other hand a connection is formed which can be released again at any time and without the use of tools.
  • slits or grooves are provided on the housing shell (36) of the handheld hair dryer instead of the strips (35), into which the hooks (23, 24) of the arms (21, 21 a) of the carrier plate (13 ) border.
  • a resilient intermediate member can also be provided, by means of which the carrier plate (13) is supported on the motor (7). With the same effect, a resilient intermediate member can also be arranged between the carrier plate (15) and the unit housing wall (20).
  • the resilient intermediate member is expediently designed as a disk made of elastic material, for example rubber.
