  • This configuration achieves a very precise and very well reproducible positioning of the light guide relative to the at least one light source. Consequently, losses associated with insufficient coupling of light into a coupling region of the light guide can be avoided to a particularly large extent.

Nevertheless, the light guide is positioned very precisely relative to the at least one light source.
  • the stop element can be arranged on a support part on which the at least one light source is held. In this way it is very easy to ensure that the light guide does not come into contact with the light source when the module attachment is installed.

Because then such operating states are particularly easy for the user of the cooking appliance to detect.
  • the viewing surface is oriented inclined from the further pane to the first pane. This is because, on the one hand, it is possible to apply grazing light to the visible surface, with the light incident flat and from the side onto the visible surface being coupled out of the light guide during operation of the at least one light source. In addition, in this way a depth effect of the module attachment is emphasized in a particularly effective manner.

  • an exact and easily reproducible distance of the light guide 20 from the light-emitting diodes 22 assigned to this light guide 20 is set.
  • an exact spacing of the light-emitting diodes 22 from a front coupling surface of the light guide 20 associated with these light-emitting diodes 22 is specified (cf 7 ).
  • the stop element 27 in the present case interacts with a projection of the light guide 20 designed in the manner of a web 29 , this web-like projection preferably being formed in one piece with a base body of the light guide 20 .
  • This projection or this shaped element of the light guide 20 is screwed tight when a cover element, presently designed as a corner cap 30 (cf 4 ) pulled into the respective corner area of the frame 10.
  • the corner cap 30 applies a contact pressure to the web 29 .
  • the web 29 is pressed against the stop element 27 with this contact pressure.
  • the stop element 27 Due to the provision of the stop element 27 , however, the light-emitting diodes 22 are protected from being subjected to the contact pressure applied to the light guide 20 . Correspondingly, impairment of or damage to the light-emitting diodes 22 during the installation of the light guide 20 in the respective corner area is avoided in a simple and reliable manner.
  • the corner connector 15 couples the two profile parts 13, 14 to one another in the respective corner region of the frame 10.
  • the circuit board 28 is preferably equipped with a heat-conducting element 33 or heat-conducting pad on the back.
  • the heat generated as a result of the operation of the light-emitting diodes 22 can be easily introduced into the respective profile part 13, 14 via this heat-conducting element 33, which has a high thermal conductivity.
  • the profile parts 13, 14 are formed from a thermally highly conductive material such as aluminum or an aluminum alloy.
  • a good thermal transition from the circuit board 28 to the respective profile part 13, 14 is ensured, and on the other hand, an optical transition of the light emitted by the light-emitting diodes 22 to the respective light guide 20 is very largely independent of tolerances.
  • the cover element in the form of the corner cap 30 shown here as an example also ensures that the two light guides 20 and their housing, i.e. the respective receiving part 21, are held securely in the respective corner area of the frame 10.
  • the profile parts 13, 14 have recessed areas in the respective corner area of the frame 10 for accommodating these components (cf 4 ).
  • the corner cap 30 ensures in particular that no stray light escapes at unwanted points in the respective corner area of the frame 10 .
  • the corner cap 30 has a first cap portion 34, which is a light coupling surface of the 4 along the profile part 13 extending first light guide 20 covers.
  • the corner cap 30 has a second cap region 35 in the present case, which covers a free end 36 of the second light guide 20 (cf 4 combined with figure 5 ), wherein the second light guide 20 extends from the corner area of the frame 10 along the second profile part 14 of the frame 10.
  • the corner cap 30 protects the circuit board 28 during the assembly process, in particular when a plug connector of a cable or similar electrical conductor is inserted into one of the connection plugs 37, which are arranged on the circuit board 28 in the present case (cf 4 ). This reliably prevents sensitive electronic components, which are preferably arranged on the circuit board 28 or circuit board, from being touched and/or soiled when such a cable is connected to one of the connection plugs 37 . In particular, the corner cap 30 prevents the light-emitting diodes 22 from being touched and/or soiled.
  • the light-emitting diodes 22 are arranged on the circuit board 28 in such a way that a respective focal point of the light-emitting diodes 22 is directed towards a central area or midpoint of a front light coupling surface of the light guide 20 . This ensures that the light emitted by the light-emitting diodes 22 during operation is coupled into the respective light guide 20 via this light-coupling surface, independent of tolerances.
  • the circuit board 28 can, as shown here by way of example, be positioned by means of the corner connector 15 in the vicinity of the screw point or screw receptacle 31 by means of a positioning element.
  • a projection designed in the manner of a web 38 which is preferably designed in one piece with a base body of the corner connector 15, can engage in a recess, for example in the form of a groove 39, which is presently designed in the circuit board 28 (cf figure 5 combined with 8 ).
  • the positioning element provided here by the web 38 can have a crushing rib 42 which, in a mounted state of the module attachment 7, allows a narrow side of the circuit board 28 to be pressed against the respective profile part 13, 14, according to 8 effected on the profile part 14. This is conducive to secure positioning of the circuit board 28 arranged in the respective corner area of the frame 10 .
  • a sealing element 40 is shown which is designed in the manner of a round cord running around the frame 10 and which is pressed against the front side 8 of the front pane 6 when the module attachment 7 is in the installed state.
  • the sealing element 40 is preferably formed from an elastic material and inserted into a groove or guide which is formed by the profile parts 13, 14 and the corner connectors 15.
  • a screw 41 is shown by way of example, which is used to fix the module attachment 7 to the windscreen 6 and thereby presses the sealing element 40 against the front side 8 of the windscreen 6 .
  • several such screws 41 can be provided in order to attach the module attachment 7 to the front pane 6 of the door 5 or cooking appliance door.
  • the corner cap 30 in the present case has a web 43 designed in the manner of a pin (cf figure 5 ), which serves in particular to pre-position the corner cap 30 when installing the module attachment 7.
  • This web 43 is in fact in an intermediate space 44 (cf figure 5 ) dipping included, which is formed between the profile parts 13, 14, which present a miter, or carrier profiles in the respective corner area of the frame 10.
  • the module attachment 7 can also have at least one locking element in the respective corner area, which secures the corner cap 30 against twisting due to the head torque applied to the corner cap 30 during the screwing process.
  • a groove or notch 46 can be formed for this purpose in a wall 45 of the corner cap 30, the wall 45 being oriented essentially perpendicularly to the longitudinal direction of the respective profile part 13, 14 in the present case.
  • this notch 46 engages 11 a corresponding wall or a corresponding wall area of the corner connector 15, so that the corner cap 30 is secured against a rotational movement that can be caused by the screwing process, ie by screwing the screw 32 into the screw receptacle 31.
  • a cost-effective design of the module attachment 7 is achieved in an advantageous manner, which can be realized with a comparatively small number of components.
  • the number of light-emitting diodes 22 can be kept comparatively small.
