Definitions

the present invention relates to a lighting device for an oven, in particular for a domestic oven, in the cooking space of which microwave energy can be coupled in, using a light source which is arranged outside the cooking space.
lighting devices with filament lamps which are arranged, for example, in the region of one of the side walls or the upper wall of the cooking chamber on the cooking chamber wall, are used to illuminate the cooking chamber.
lighting devices that protrude into the cooking space have disadvantages of a special kind With microwave field strengths, the incandescent filaments of known lamp arrangements are made to glow when the lamp protrudes freely, ie without microwave shielding into the furnace space.
the present invention has for its object to provide a lighting device which is arranged in addition to simple construction technology outside the cooking chamber.
a lighting device which corresponds to this task is characterized according to the invention in that a microwave-proof glass cover of the light source inlet opening for the cooking space is attached on the one hand outside of the cooking space, on the other hand is at least partially accessible on the cooking space side and is arranged almost flush with the oven wall.
the lighting device according to the invention is characterized in that the glass cover has knobs on the cooking space side, which are connected to a surface perforated panel, so that a metallic surface perforated panel with a glass-filled perforated pattern is produced, the metal surface perforated panel being arranged almost flush with the oven wall is accessible on the cooking space side.
the oven lamp 1 shows an oven lamp 1, a knobbed glass cover 2, an outer edge 3 of the knobbed glass cover 2, a metallic fastening pocket 4, an oven jacket 5, glass knobs 6, metallic surface perforated covers 7 and a cooking chamber 8.
the oven lamp 1, which can be a halogen lamp, for example, is located behind the nubbed glass cover 2 outside the indicated cooking space 8.
the glass knobs 6 of the glass cover 2 are connected to the metallic surface perforated screen 7.
the outer edge 3 of the glass cover 2 is arranged in the metal fastening pocket 4, which is connected to the oven jacket 5.
the pimpled glass cover 2 receives fastening stability.
a cleaning of possibly soiled glass knobs 6, which can be carried out on the cooking chamber side, does not impair the functional safety of the knobbed glass cover 2 (for example, it is not possible to push off the knobbed glass cover 2).
the knobbed glass cover 2 can also be designed as a circular surface.
the holding pocket 4 is designed as a circumferential ring, but at least as a two-point holder.
the connection between the holding pocket 4 and the knobbed glass cover is realized by gluing.
the holding pocket 4 is formed by spot welding, gluing or screwing the metallic surfaces.
FIG. 2 shows an oven lamp 1, a wire glass pane 2.1, an outer edge of the wire glass pane 3.1, a slot holder 4.1, an oven jacket 5, a microwave-tight wire rack 7.1, an indicated cooking chamber 8 and a metallic contact surface 9.
the wire glass pane 2.1 covers the light source inlet opening for the cooking space in a microwave-tight manner, since the microwave-tight wire mesh 7.1 encapsulated in glass, which is electrically contacted with the oven wall 5, provides microwave tightness brings about.
the electrical contact between the wire mesh 7.1 and the oven wall 5 takes place on the outer edge of the wire glass pane 2.1.
the wire mesh 7.1 lies freely on the lower side of the outer edge 3.1 on the contact surface 9 and forms a short-circuit bridge for the microwave to the oven wall 5.
the wire glass pane 2.1 like the nubbed glass cover 2, is to be cleaned on the cooking chamber side.
the wire glass pane 2.1 can be designed as a rectangular area or circular area, as has already been described under the nubby glass cover.
the same principle applies analogously to the holding of the wire glass pane 2.1 as for the nubbed glass cover 2, the holding pocket 4 being emaciated as a slot holder 4.1.
the connection of the wire glass pane 2.1 with the slot holder 4.1 is achieved by gluing.
