  • the holding device for an operating and / or display device of a household appliance, in particular a cooker, is provided.
  • the holding device can also be used and used on other household appliances such as dishwashers, washing machines, dryers, etc.
  • a control and display device 1 is shown in a partially sectioned side view, which has a holding device 2 according to the invention.
  • the holding device 2 is formed in the case of the present embodiment as a holding frame 2 and shown in enlarged form again in Figure 2 in perspective.
  • the holding frame 2 is a plastic injection-molded part.
  • the support frame 2 is thus formed in the present case of plastic.
  • the holding frame 2 may also be formed of a different material, for example of a metal or a metal alloy.
  • the holding frame 2 in the case of the present embodiment, three shots 3.
  • the receptacles 3 are present in the form of a ring or hollow cylinder and, as can be seen from FIG. 1, have a longitudinal extent.
  • the receptacles 3 are three guides 3 for each control element, which in the case of the present exemplary embodiment is a T-shaped button 4 in each case.
  • the holding frame 2 also has an integrated fastening device 6 for the arrangement of at least one further component or a further component on the support frame 2.
  • the fastening device 6 is a latching device 6 comprising three retaining lugs 5 and two latching hooks 28.
  • a T-shaped key 4 is arranged in one of the annular or hollow cylindrical receptacles or guides 3.
  • the electronic component 7 is hooked under the retaining lugs 5 and locked by means of the latching hooks 28.
  • the electronic component 7 has, inter alia, a circuit board 9 with electrical components as well as interconnects connecting the components.
  • a display unit 10 is arranged on the front side of the circuit board 9.
  • the switches 11 are operated with the keys 4, which keys 4 are sprung against the frame 8 in the case of the present embodiment. Thus, if a key 4 is pressed by pressing, it moves to its associated switch 11 of the board 9 and actuates it. After releasing the key 4, this is moved back by the spring means not shown in their initial position.
  • the operating and display device 1 further comprises a diaphragm 12, which is formed in the case of the present embodiment of a metal.
  • the diaphragm 12 may also be formed of a metal alloy or of a plastic coated with a metal.
