  • the circumference of the upper base portion 34b tapers toward a tapering portion 35b, and then increases upward toward a second upper abutment portion 35c.
  • the circumference of the first lower abutment region 35a is expediently the same as or greater than the circumferential region of the upper, second upper abutment region 35c.
  • the plugged-on support member 20 thereby has two preferably circumferential and accurately fitting contact areas, which correspond to the first lower abutment portion 35a and the second upper abutment portion 35c of the base 34, to ensure a good and stable support of the support member 20 on the base 34 in its axial direction.
  • the formation of the tapered portion 35b advantageously prevents penetration of liquid and dirt due to capillary action over the first lower abutment portion 35a in the upper-side direction, and also reduces a frictional force upon fitting or detachment. On the one hand a good hold and on the other hand a good solubility for later cleaning purposes are ensured.
  • the base 34 and the corresponding base receiving portion of the support member 20 are rotationally symmetrical or radially symmetrical about its longitudinal axis, so that they are manufacturable in a simple manner.
  • the guide element 36a of the base 34 is a pin or laterally projecting from the circumference pin or adapted to the dimension of the pin pin guide as a matching guide element 20a of the support member 20.

  • the base 34 has a central base foot as the lower base portion 34a, which is designed for re-removable insertion into a socket-receiving opening, wherein the socket receiving opening leads from the top into the door and in particular through an opening of the glass ceramic plate 19 passes.
  • the base 34 and the socket receiving opening are equipped with matched guide elements to align the pedestal 34 relative to the orientation of the door 7 and preferably to be able to lock in this position in the axial direction.
  • the projection 34c which separates the upper base portion 34b and the lower base portion 34a, has several preferred features.
  • a circumferential groove 37 is formed, over which the lower portion of the support member 20 is still slidable to touch on the top of the projection 34c.
  • the groove 37 prevents liquid penetrating between the top of the protrusion 34c and the bottom surface of the support member 20 from being further drawn by capillary action between the components.
  • the protrusion 34c at the outer peripheral edge directed downwards has a circumferential foot or a sequence of feet which slightly project downwards towards the surface of the door, that is to the glass ceramic plate 19 and sit on this.
  • This free space also causes a liquid can not penetrate into the transition region of the lower base portion 34a and the socket-receiving opening and thus provides advantageous contamination protection and protection against capillary effects.
