Definitions

  • the invention relates to an operating unit for cooking, cooling and Cleaning apparatus, in particular household cooking appliances.
  • a known cooking appliance according to DE 196 10 921 C2 has Hob on which an opening surrounded by a guard ring is formed, wherein the guard ring, the upper edge The opening is concealed and at a reaching into the opening End has a thread. Located under the opening a threaded receptacle, the the lower edge of the opening is concealed and with the guard ring is screwed. Perpendicular to the hob area is a retractable Operating element arranged, the hollow knob by the protective ring and its fullness also through the collecting container passed through. The collecting container serves to overflowing Cooked food and other liquids by the narrow passage between guard ring and gag, catch.
  • the trained as a rotary switch control can be sunk by finger pressure in the control panel, if it is not needed, and extend by pressing the finger again, when turning positions are desired (see also DE 199 51 422 A1 and publications mentioned therein).
  • the most essential Disadvantage of this solution is that despite high Assembly costs there is a risk of loosening.
  • the invention is based on the object, a control unit for cooking, refrigerating and cleaning appliances, in particular household cooking appliances, to create that easy and safe mountable is.
  • the receptacle can be cup-shaped and / or rotationally fixed in be included in the plate.
  • the fastener is preferably supported in one predetermined axial position latching on the first hollow shaft from. It has in particular a second shoulder, which in axial direction is at least partially resilient.
  • the fastening element has in particular a second Hollow shaft, arranged on the inner wall first locking elements are that with second locking elements on the outer wall of the first hollow shaft cooperate, and first Screw elements are arranged, with second screw elements cooperate on the outer wall of the first hollow shaft.
  • first screw to each other offset by 180 degrees and the second screw offset by 180 degrees to each other and the other the first Locking elements offset by 180 degrees to each other and the second Latching elements arranged offset from each other by 180 degrees, wherein the locking elements and the screw elements to each other in particular offset by 90 degrees.
  • the first screw elements are preferably along the second screw elements feasible and in the end position this wegbegrenzend applied, while the first locking elements preferably can be snapped over the second locking elements.
  • first locking elements on the second Snapping snapped when the first screw on abut the second screw elements wegbegrenzend.
  • the fastening element can be designed as a union nut be on the first hollow shaft axially deliverable and in Can be locked in a predetermined axial position.
  • the operating unit 2 consists of a control panel forming a Sheet metal section 4 with an opening (form hole) 6, a in the opening (shape hole) 6 usable scale pot 8, a sliding in the scale pot and rotatable countersunk knob 10 and a receiving on the scale pot 8 union nut 12, with the exception of the control panel all molded parts, in particular Plastic moldings are.
  • the opening (molding hole) 6 is circular with 4 inwards pointing projections (teeth) 14 formed.
  • the scale pot 8 has a cup-shaped part 16 with a cylindrical hollow shaft 18 and a bottom 20 in which a central opening 22 is located, through which the switching shaft an unillustrated rotary switch, for example Energyreglers, is plugged through.
  • the open side of the Hollow shaft 18 is by an outwardly facing annular Shoulder 26 completed.
  • a circular ring 24 is arranged, which when plugging of the countersunk knob 10 on the not shown Shift shaft limits the Aufsteckweg to a safe alignment the preferably spherically curved top surfaces of the Retractable knob 10 and the annular shoulder 26 to a uniform Guarantee deck area.
  • coaxial arc On a distance from the transverse webs 34 coaxial arc are located on the outer wall 28 of the hollow shaft 18 two 180 degrees offset to each other short (about one Quarter circle corresponding) ringbahnen 36, each off a curved against the circular arc longer portion 38th and a shoulder closer to the arc shorter section 40 exist, at its free end in an axis-parallel section 42 passes, which in turn extends in the direction of the shoulder 26.
  • the two ends of the Screw ties 36 are also with an arrow-shaped connected in the direction of the bottom 20 extending guide web 44.
  • the outer wall 28 of the hollow shaft 18 carries two to each other by 180 staggered nubs 46, to the sections 42 about 90 degrees are offset.
  • the hollow shaft 18 has two opposite lateral openings 48 on, extending below the arrow-shaped Guide webs 44 axially parallel to the floor 20 extend to.
  • the union nut 12 has a hollow shaft 52, of which to the control panel pointing one end four by 90 each Degree displaced relatively rigid contact surfaces 54 obliquely extend outside, between each of which three resilient contact surfaces 56 are arranged, which are approximately the same length extending obliquely outwards from the same hollow shaft end, but under a slightly more inclined to the longitudinal axis Angle.
  • the rigid contact surfaces 54 at the same inclination as the resilient contact surfaces also be arranged axially reset.
  • In the plan view shows the entirety of the contact surfaces 54 and 56 like a flower crown.
  • the scale pot 8 with its hollow shaft 18 of the operating side forth in the opening 6 of the sheet metal section. 1 inserted until the elevations (ribs) 30 of the hollow shaft 18 enter between the projections (teeth) 14 in a form-fitting manner, to secure the scale pot against twisting, and finally the shoulder 26 on the operator facing surface of the Blechabiteses abuts, both as an axial fixed stop as well as a seal against penetrating liquids of all Way of acting.
  • the union nut 12 is rotated until two of its Angled webs 60 first with their closed side first along the inclined helical sections (helical Contours) 38 slide and so an axial feed in the direction of the user-facing surface of the Blechabiteses 1 effect.
  • the resilient abutment surfaces 56 sooner or later to the sheet metal section 1 and finally under ever stronger Tension whose level is maintained when the two Angled webs 60 along the coaxial fferbahnabête 40th move.
  • the operating unit shown here with the known advantages of countersunk knobs is easy and economical to assemble and disassemble with high safety due to radial and axial fixation (positive engagement or locking), material thickness differences are compensated for example stainless steel and paint panels.
