Definitions

  • the invention relates to a switching and control device, in particular for ovens, according to the preamble of claim 1.
  • Such combinations of switches and controllers are also referred to as UOG switches because they can be used to switch on bottom heat (temperature-controlled), top heat and grill position. It is therefore necessary to be able to control further switching positions of the cam switch at the end of the control range of the controller.
  • the object of the invention is therefore to provide a switching and regulating device of the type mentioned at the outset which enables simplified manufacture and assembly.
  • the slip or snap-in clutch becomes effective and enables the shift drum of the switch to rotate relative to the fixed setting shaft of the controller.
  • the inhibition of the controller-side coupling part prevents the controller-side coupling part from immediately starting to turn back, as a result of which the synchronization between the controller and the switch would be canceled. Since the clutch runs back more easily than the controller, it is ensured that the clutch first returns to the position at which it was disengaged, and then, for example by means of a driving stop, takes the controller again.
  • the inhibition of the controller-side coupling part is preferably generated by a resilient catch, but can also be generated by friction.
  • the groove can be present both directly on the controller-side connection part in the area of the switch or on the controller, the natural friction in the controller being able to help at least partially.
  • a clutch which could be called an intermediate thing between the slip and snap-in clutch, and which consists of two superimposed, preferably frontal clutch surfaces, which are provided with cams or toothed in such a way that they are in the engaged state in which that is, the shafts of the controller and switch rotate together, mesh with one another, while when disengaging they can lift off from each other against the force of a spring, preferably axially compressing them, and twist against each other.
  • This achieves a coupling effect in which after the coupling point has been exceeded (disengagement of the cams) the resistance to turning further becomes relatively low again.
  • the clutch snaps resiliently, so that the synchronization is inevitably restored.
  • a driving stop acting in the reverse direction of rotation comes into engagement between the two coupling halves, which ensures a positive coupling in this direction.
  • the cam switch 11 shown in FIG. 1 has a switch housing 12 made of insulating material, in which a switch shaft 13 is mounted which drives a switching drum 14.
  • the shift drum has at its remote end a deep central recess into which a sleeve-shaped coupling part 17 engages and rotates and delimits it can move axially.
  • the coupling part then has, on its part guided in the recess 16, a flange 18 which covers the end surface (coupling surface 19) which is remote from the operator with the inner end surface of its flange (coupling surface 20).
  • the two coupling surfaces are profiled in a manner which will be explained later.
  • the flange 18 lies in a U-shaped recess 21 of the switch housing 12 and thus forms the rear bearing for the shift drum.
  • the shift drum is secured in the recess 21 by a projection 22 of a rear metal plate 23 which overlaps the flange 18.
  • the metal sign 23 has a multiple function.
  • projections 24 for non-rotatably coupling the controller 25 and also has a leaf spring 26 in the form of a tab cut out from it, which axially on the outer end face 27 of the coupling part 17 presses and thus presses the two coupling surfaces 19 and 20 against each other.
  • a recess 28 see, for example, FIG.
  • the shield 23 is fastened to the housing 12 by means of spring catches 40.
  • the controller 25 has an adjusting shaft 29, which is accommodated in a rotationally fixed manner in the interior of the coupling part 17.
  • Figures 2 to 5 show the profile of the two coupling surfaces. It can be seen that the two profiles occupy an annular area on the end face and are mirror images of one another, so that the profiles engage in the engaged position.
  • Each profiling consists of some, in the example shown 3 obliquely triangular projections and recesses (cams 30), a section 31 which springs back on the shift drum 14 and which a projecting section 32 on the coupling tion part 17 or the clutch surface 20 is opposite and a projecting on the clutch surface 19 of the shift drum section 33, which corresponds to a rear section 34 on the opposite clutch surface 20. Between the protruding and recessed sections there is a steep step 35 on both coupling surfaces 19, 20.
  • FIG. 6 shows the clutch 36 engaged, in which the profiled surfaces, which correspond to one another in mirror image, rest against one another and engage in one another. This state is maintained from the switch position 0 ° (off position) to the end of the control range of the temperature controller 25.
  • This control range normally ends at approximately 270 ° in the angle of rotation of the switch shaft 13 and the control shaft 29 which is synchronously coupled in this area certain desired inhibition of the switch and controller against unintentional adjustment.
  • Fig. 7 shows the clutch 36 at the end of the control range (at about 270 ° setting angle). It can be seen that the clutch 36 is still engaged, i. the surfaces 19, 20 are still completely on top of each other, but the leaf spring 26 is snapped into the recess 28 so that the coupling part 17 is braked. At the same time, the range of rotation angles of the regulator shaft 29 in the temperature regulator is normally limited by a stop, so that the coupling part 17 also stops because of this.
  • the switching drum 14 opens or closes 15 contacts by moving switching springs without the control shaft 29 of the temperature controller moving. 6 to 8 viewed from the right in a clockwise direction, i.e. in the direction of arrow 37, the coupling surface 19 of the shift drum 14 runs back to the coupling point (in the example at 270 °) when turning back against the direction of rotation 37. It should be noted that when disengaging after an initial resistance to the axial movement of the coupling part 17 against the force of the leaf spring 26, the adjustment of the shift drum relative to the clutch part 117 is relatively easy.
