Definitions

  • the subject of the invention is a programme selection knob assembly, especially of a household appliance, said knob allowing a user to select and switch on one of possible programmes for appliance operation, whereby the symbol of the selected programme is also illuminated.
  • the technical problem solved by the invention is how to conceive such structure of a programme selection switch assembly especially in a household appliance that switches on one of possible programmes upon manual selection and simultaneously automatically also turning on an adequate luminous sign denoting the selected programme or the current selection or status of the programme (on knobs that automatically rotate during the operation of the appliance).
  • the structure should be such to meet quality requirements and adequate life span of all the remaining assemblies of a machine or an appliance for which it is intended despite an acceptable price expected in batch production and it should also allow various design variations both in the aesthetic and ergonomic aspects, moreover it should enable the user to intuitively understand the indication of operation of a selected programme.
  • Luminous signs for the indication of the selected setting of a programme and/or current operation indication of an appliance have long been in use.
  • a disadvantage of these known solutions is in that a large number of component parts extends the assembly time, increases breakdown possibility and the price.
  • a programme selection knob assembly of the invention the essential characteristic of which lies in that one single luminous element is used for indicating several programme places, said luminous element being preferably a diode, whereby the luminous element is stiffly connected with the selection knob to rotate with it behind a mask with transparent windows at the indication for an individual programme.
  • Two electric contacts of a luminous element simultaneously run along a pair of concentric electrically conductive circumferences, which are energized when the appliance is switched on, causing also the luminous element to glow.
  • a rotating knob 2 of a programme selection switch On the control panel 1 there is a rotating knob 2 of a programme selection switch not shown on figures. When the knob 2 is rotated the axle of the programme selection switch also rotates.
  • a support 4 of a luminous element 5, preferably a diode At the back side of the panel 1 on the knob 2 there is a support 4 of a luminous element 5, preferably a diode. Within the holder 4 there is the luminous element 5, so that its electric contacts 6 are free.
  • the luminous element 5 is positioned on the support 4 at a distance from the rotating axis of the knob 2 equalling to the radius of the circumference, on which transparent windows 7 are arranged on the panel 1, said windows denoting the selected operation programme or rather the current setting or status of this programme.
  • the electric contacts 6 of the luminous element 5 are rigidly galvanically linked to two elastic and electrically conductive sliding elements 8 that are in contact and slide along two concentric contact circumferences 9 when the knob 2 is rotated, said sliding elements being under voltage when the appliance is electrically switched on and positioned on the basic electronic board 10 positioned behind the control panel 1.
  • indications of 11 programmes Near the transparent windows 7 on the panel 1 there are indications of 11 programmes.
  • Angular arrangement of indications 11 corresponds to the current selection or status of the programme as a function of rotation of the programme selection switch axle.
  • the contact circumferences 9 are under voltage. Due to electric contact via elastic sliding elements 8 also the luminous element 5 is under voltage, said element thus glowing regardless of knob rotation.
  • the luminous element 5 moves behind a transparent window 7 positioned at the indication of a selected programme. The light of the element 5 transfers to the surface of the transparent window 7, which is perceived by the user as a light turned on at a selected programme.
  • the described embodiment includes one luminous element 5 indicating each individual indication 11 through its belonging transparent window 7.
  • each luminous element 5 and several windows 7 for each indication 11 are possible, whereby each luminous element turns on via additional switches for the switch-on of subprogrammes or other functions of the appliance.
