Definitions

  • the invention relates to a multi-function switch for electrical devices with the features contained in the first part of claim 1.
  • Multi-function switches are very common in technology.
  • the switch by means of which the turn signal lights can be actuated alternately by pivoting a shift lever, is designed in such a way that the flasher and an acoustic horn can be actuated by tilting the shift lever transversely to its pivoting direction.
  • a so-called cord switch which can be inserted into an electrical cable, which has a tubular housing containing insertion openings for the cable for accommodating electrical and / or electronic devices as well as a multi-function actuator which can be moved and rotated to influence these devices .
  • This multi-function actuator is designed as an annular body that covers the parting line of the cross-divided switch housing consisting of two pipe bodies that can be joined together.
  • the disadvantage of this known cord switch is the arrangement of a switching slide interacting with the annular actuating element and acting on a single-stage microswitch, which slide switch can only be mounted in the housing if the housing has a parting line running transversely to its longitudinal direction.
  • an actuator in the form of a closed ring body on the handle of electrical devices can only be used to a limited extent; Because, for example, he would limit the available, hand-enclosable handle length of a so-called gun-shaped hand hair dryer so that the device would no longer be comfortable and safe to hold and the one-handed switch operation would be extremely difficult.
  • a multi-function switch is also described and shown in WO 80/01 736, but is primarily suitable for elongated, rod-shaped electrical devices, since its switching ring provided as a rotary-sliding switching element generally requires additional overall length in the extension of the grip area.
  • a switching device known from DE-A2708981 on the other hand, only the actuation of a single slide switch, that is to say only a simple switching function, is possible.
  • the present invention is therefore based on the object of providing a multi-function switch for electrical devices which can be operated by hand, with which the device is simultaneously held and guided by its handle.
  • the switch should be integrated in the handle so that its interior is used as optimally as possible.
  • this object is achieved according to the invention by a multifunction switch according to claim 1.
  • this switch has the special characteristics of claim 2.
  • the hand-held hair dryer essentially consists of two housing shells 1 and 2, a perforated air inlet cap 3 that closes off the rear of the housing shell 1, the heating register 4, the blower motor 5 with fan wheel 6 and the air outlet grille 7 Slide switch 9 and other electrical components and connecting parts 10, 11, 12 necessary for controlling the motor 5 and the heating register 4 are fastened.
  • the inner wall 14 of the handle G formed from the housing shells 1 and 2 has a circular cylindrical shape, wherein in the area of the slide switch 9, a switching movement transmission member 15 with a lever shoulder 16 is mounted so that it is in the direction of arrow P, i.e. H. in the longitudinal direction of the handle, is displaceable and also pivotable about the longitudinal axis L of the handle G.
  • the transmission member 15 has the shape of a hollow cylinder segment. Its curved inside 17 has a rib 18 with internal toothing 20 which engages in a corresponding toothed roller 21, which in turn is connected to the axis of rotation of the rotationally adjustable electrical component 11 and is used to adjust the electrical value of this component 11.
  • a web 19 is provided parallel to the rib 18 and engages in a slot 22 on the actuating part 23 of the slide switch 9.
  • the transmission member 15 is now rotated about the longitudinal axis L of the handle G by pivoting the lever shoulder 16, the toothed roller 21 is rotated via the internal toothing 20 and thus the value of the electrical component 11, for example a potentiometer influencing the heating output of the heating register 4, is adjusted.
  • the slide switch 9 can be actuated and in this way, for example, the speed of the blower motor 5 can be changed by moving the transmission element 15 in the direction of arrow P or counter to the direction of arrow P.
  • the shape of the rotatable and slidable transmission member 15 according to the invention in the form of a hollow cylinder segment, the printed circuit board 8, the upper narrow side of which is held by a groove 24 on the air guide ring 25, and on which, in addition to the switching elements 9, 11 and 21 of the multifunction switch, can also be used other electrical components 10, 12 of the hair dryer can be accommodated in a space-efficient manner, extend through the interior space encompassed by the transmission element 15 and nevertheless with it extend a longitudinal edge to the inner wall of the handle G, where it is fixed to a projection 27.
  • a gap 26 is provided between the other longitudinal edge of the printed circuit board 8 and the handle inner wall 14, which ensures the unimpeded free rotation and displacement of the transmission member 15.
  • the transmission member 15 On its outside, the transmission member 15 has a narrow elevation 28 which serves as an index and thus enables the respective position of the actuating part 15 to be read easily relative to the scale 29.
  • two functions of a device - such as e.g. B. the setting of both the temperature and the fan speed of a hair dryer - can be controlled with one hand without the hand having to change its position on the handle G; because the thumb of the grip hand is almost inevitably on the lever shoulder 16 and can move and / or pivot it together with the transmission member 15.
