Definitions

  • the invention relates to an arrangement for displaying power on an electrical device, the power of which can be adjusted by hand by actuating the adjusting element of an electrical actuator, which arrangement has a plurality of display elements on a housing wall of the device which display different power levels.
  • a vacuum cleaner with a power indicator is known.
  • several indicator lamps are arranged on the top of the vacuum cleaner housing, each of which indicates a specific power level. Attaching these indicator lamps to the vacuum cleaner housing and electrically connecting them requires a correspondingly high amount of time. A step-by-step mechanism is also required in order to control the individual lamps according to the power set.
  • a plurality of display elements designed as light guides are arranged on the vacuum cleaner housing. Between a light source illuminating the light guide and the inputs of the light guide there is a screen which is connected to a membrane acted upon by the pressure difference in front of and behind the filter bag. The screen is thus adjusted as a function of this pressure difference and correspondingly releases more or fewer inputs of the light guide, the display area of which then lights up on the top of the vacuum cleaner housing. The more the filter bag is filled with dirt, the more display areas light up, so that the user of the vacuum cleaner can recognize the increasing degree of filling.
  • This vacuum cleaner does not have a single display of the power of the blower motor.
  • the invention has for its object to provide an arrangement for power display on an electrical device that requires less assembly and in which no step switch is required to display the individual power levels.
  • each display element can be illuminated by means of a light guide, the individual light guides being arranged in such a way that the light guide, which is assigned to the display element displaying this power level, corresponds to the position of the adjusting element corresponding to a specific power level. with its entrance facing the emitting side of a light source arranged on the adjusting element.
  • the adjusting member of the actuator is actuated and the light source arranged on the adjusting member is moved past the light guides, so that the light source is in front of the corresponding light guide after reaching the desired power level and illuminates the display element for this power level via this.
  • the newly set power level is thus displayed for each power adjustment without additional components.
  • a display area perceptible through an opening in the housing wall is formed on each light guide.
  • a closed surface of the device housing is achieved in that the display surfaces of the light guides are arranged flush with the surface thereof in adjacent openings in the housing wall.
  • the light guides are supported by a continuous bar that can be attached to the housing.
  • the power setting in stages can be achieved in a simple manner in that the electrical actuator consists of the series connection of fixed resistors and has a tap between the individual resistors.
  • a rectilinear arrangement of the display surface is possible in that the fixed resistors are arranged on a linear circuit board and the adjusting element is designed as a slide.
  • the fact that the slide is arranged displaceably on the housing of the device and the circuit board is held on the housing results in a robust embodiment for the power adjustment device.
  • the electrical supply of the light source arranged on the slide is achieved in that conductor tracks cooperating with corresponding slide contacts of the slide are provided on the circuit board and the slide contacts are connected to the connections of a lamp arranged on the slide.
  • a vacuum cleaner housing 1 with a vacuum cleaner housing is designated, on which a slide 2 is slidably arranged, which cooperates with a circuit board 3 carrying the electrical actuators for the speed control of the blower motor.
  • a display field 5 consisting of individual display elements 4 is provided on the vacuum cleaner housing 1.
  • the display elements 4 consist of a light guide 6, which has its input 7 attached to the slide 2 Lamp 8 protrudes. The other end of the light guide 6 is inserted flush with the surface of the vacuum cleaner housing 1 in a corresponding opening 9 thereof and forms a display surface 10.
  • the slide 2 has a leg 12 running parallel to its grip part 11, with which it engages under the base wall 13 of a guide trough 14 formed on the vacuum cleaner housing 1.
  • a contact carrier part 15 is formed thereon, on which sliding contacts 16 are arranged, which rest on conductor tracks 17, 17a and 17b provided on the circuit board 3 and slide on the slide 2 when the latter is adjusted.
  • Two conductor tracks 17 and 17a are formed continuously so that the supply voltage for the lamp 8 arranged on the slide 2 can be tapped via these two conductor tracks 17 and 17a.
  • the sliding contacts 16 interacting with these conductor tracks 17 and 17a are electrically connected to the lamp 8.
  • the circuit board 3 is inserted and held in slots 18 formed on the vacuum cleaner housing 1.
  • a second lamp 19 which faces a corresponding light guide 6, is also fixedly arranged on the board 3.
  • the second lamp 19 is controlled by a pressure switch 20 which is acted upon by the pressure difference prevailing in front of and behind the filter bag of the vacuum cleaner. A necessary change of the filter bag is thus signaled by the display surface 21 of the light guide 6 assigned to the second lamp 19 when the pressure switch responds as a result of the increasing pressure difference when the filter bag is full.
  • a plurality of fixed resistors 22 are arranged on one side of the circuit board 3 and are connected in series with one another. The connections of these fixed resistors 22 are connected on the other side of the circuit board 3 to segments 23 which are arranged in a line to form the conductor track 17b.
  • segments 23 which are arranged in a line to form the conductor track 17b.
  • a corresponding sliding contact 16 arranged on the slide 2 a conductive connection between the individual segments 23 and the conductor track 17 a is established.
  • the number of fixed resistors 22 effective in the speed control circuit connected to the output contact 24 of the series resistor circuit is thus changed, and the output of the vacuum cleaner fan is thus adjusted.
  • the sliding contact 16 assigned to the segments 23 is so wide that the distance 25 between two segments is safely bridged and thus a current interruption in the speed control circuit is avoided.
  • the lamp 8 is inserted between two semicircular retaining tabs 26 which are formed on the underside of the leg 12.
  • the connecting wires 27 of the lamp 8 are guided to contact tabs 28 which are integrally connected to the sliding contacts 16 and are in contact with them.
  • the number of fixed resistors 22 effective in the speed control circuit is changed, thereby adjusting the performance of the vacuum cleaner fan.
  • the lamp 8 connected to it comes in front of another light guide 6, which is then illuminated by the lamp 8.
  • the other end of the light guide 6 in question which acts as a display surface 10, then appears illuminated and thus indicates the power that has been set in each case.
  • the lamp 8 can be relatively bright, so that the display surface 10 of the light guide 6 is appropriately illuminated. This means that the display is still clearly perceptible even in unfavorable lighting conditions.
  • the light guides 6 are connected to one another by a strip 29.
  • all light guides 6 can be attached to the vacuum cleaner housing in a single assembly process.
