  • DE 103 18 859 A1 , DE 103 18 860 A1 , DE 103 18 861 A1 and DE 103 14 543 A1 show means for illumination having also a prismatic reflector element.
  • a container element which is part of means for illuminating the cavity and which has a substantial prismatic form.
  • a plurality of mirrors is arranged in longitudinal direction of the container element.
  • a substantial classical reflector with lamp is used in DE 101 22 878 A1 , in DE 86 02 774 U1 and in DE 34 04 430 A1 to illuminate the cavity.
  • the pre-known means for illumination of the cavity have often a quite complex design.
  • the costs for producing and mounting the systems are high, accordingly.
  • the pre-known solutions do not always ensure that a blind-free illumination of the cavity can be obtained.
  • the reflector element of the illumination means has a first section which extends substantial in a longitudinal direction with flat wall elements and has a second section with wall elements, wherein at least on of the wall elements has a bow-shaped form.
  • the reflector element is made as a one-piece element.
  • the extension of the second section is preferably between 30 % and 85 % of the entire length of the reflector element; specifically preferred is an extension of the second section which is between 40 % and 60 % of the entire length of the reflector element.
  • the lamp can be arranged outside the reflector element.
  • a concentration element can be arranged between the lamp and the reflector element to bundle the light of the lamp.
  • the concentration element can be part of the socket or of the housing of the lamp. It can be made of a coating on the lamp or its socket and housing respectively.
  • one single lamp is arranged in or at the reflector element.
  • a preferred embodiment of the invention has at.least one flat wall element, wherein the plane of the wall element and the plane of a cavity wall enclose an angle. This angle is preferably between 30° and 60°, specifically 45°
  • a further aspect of the invention is that a first blind is arranged between the reflector.element and the cavity wall.
  • the first blind can be part of the reflector element.
  • a part of the wall elements of the reflector element can be coated it improve the reflection of the light to better distribute the light.
  • a transparent plate can be arranged in the opening of the reflector element.
  • This transparent plate is preferably made of glass.
  • a further preferred embodiment of the invention suggests a second blind which is arranged on or at the transparent plate.
  • the second blind can be made of sheet metal or of a foil. It can be printed on the transparent plate.
  • At least one aperture can be arranged in the second blind. More specifically, a plurality of square apertures can be arranged in the second blind to illuminate the different levels of the cavity. Furthermore, the aperture can have the shape of an alphabetic character or of a cipher.
  • the at least one aperture - preferably a plurality of apertures - corresponds to a defined level of a tray in the cooking cavity of the oven.
  • the reflector element is arranged remote from a rear wall of the cavity. It can be arranged in the side region of the cavity near a door. Preferably, two reflector elements are arranged in both side region of the cavity.
  • the longitudinal direction of the reflector element is extending vertically.
  • the illumination of the cavity can occur with a minimum of lamps.
  • all levels of the cavity in vertical direction can sufficiently be illuminated with the proposed design.
  • the light from the lamp leaves the means for illumination by being reflected by the walls of the reflector element and not directly via the lamp, i. e. an indirect illumination of the cavity takes place. Therefore, no "hot spot" exists which can be the source for blinding.
  • the lamp is preferably not visible from the cavity no blinding effect can come into being. This is also ensured by the fact that the light is preferably emitted by the means for illumination from the front side of the cavity to the rear region of the cavity.
  • the whole vertical-extension of the cavity can be sufficiently illuminated by the means, i. e. all levels where baking trays are arranged.
  • the blind can have characters or ciphers which can be illuminated by only one lamp.
  • a numbering for the levels of the cavity can be displayed in an illuminated manner or a logo without employing a separate lamp.
  • a preferred solution comes up with the arrangement of the means for illuminating in the front side region; in this case the means can illuminate the cavity from the front region to the rear region.
  • the.lamp is not visible when looking into the cavity from the front, even when it is installed in the reflector element; the lamp can thus be covered by the reflector element.
  • FIG 1 and in FIG 2 a domestic oven 1 is depicted having a cooking cavity 2 as usual. While FIG 1 shows the sectional top plan view, FIG 2 shows the sectional bottom plan view.
  • the cavity 2 is closable by a door (not depicted).
  • To illuminate the cavity 2 means 3 for illuminating are employed. Those means 3 are arranged on both side regions 22 and 23 of the cavity 2, remote from the rear wall 21, i. e. in the front region of the cavity.
  • the means 3 for illuminating the cavity 2 are depicted in detail in FIG 3 till FIG 6 according to a first embodiment of the invention.
  • the means 3 have a reflector element 4 having a longitudinal direction L. At one end of the reflector element 4 a lamp 5 is arranged. The lamp 5 is positioned outside the reflector element 4. A concentration element 15 is employed to focus the light of the lamp 5 and to.lead it into the reflector element 4. The concentration element 15 can be a part of the socket of the lamp 5.
  • an opening 6 is formed into the reflector element 4.
  • the light can thus leave the reflector element 4 and can illuminate the cavity.
  • the specific form of the reflector element 4 is shown in FIG 3 till FIG 6 .
  • the reflector element 4 extends along a certain length L 0 . It has a first section 7 which has a substantial prismatic form, which extends in the longitudinal direction.
  • the reflector element 4 is here formed by three wall elements 8, 9 and 10. While the wall elements 8 and 9 are arranged parallel or perpendicular to the plane of the cavity wall 16 this is not the case for the third wall element 10. As can be seen from FIG 4 and FIG 5 this wall element 10 is arranged under an angel ⁇ to the plane of the cavity wall 16 which is about 45°.
  • the reflector element 4 has furthermore a second section 11, also extending in the longitudinal direction L.
  • the reflector element 4 is also formed by three wall elements 12, 13 and 14. While the wall elements 12 and 14 are flat as the wall elements 8, 9 and 10 this is not the case for the wall element 13. This wall, element 13 is curved (arcuated) as can be seen specifically from FIG 3 .
  • the extension of the second section 11 is denoted with L 2 in FIG 3 .
  • This extension L 2 is preferably between 40% and 60% of the entire length L 0 of the reflector element 4.
  • the reflector element 4 has furthermore a first blind 17 as can be seen from FIG 4 , FIG 5 and FIG 6 .
  • This blind 17 covers a part of the beams from the lamp 5. Consequently, no blinding can occur depending on the width of the blind 17.
  • the reflector element 4 is made of a one-piece element. More specifically, a sheet metal part is edge bended to obtain the depicted form.
  • the ends 24 and 25 of the reflector element 4 are bended so that the reflector element 4 can be easily mounted into the aperture in the cavity wall 16. Thus, a snap-fit connection is obtained.
  • This plate 18 is a glass plate which prevents that any dirt enters from the cavity 2 into the reflector element 4.
  • FIG 7 An alternative embodiment of the invention is shown in FIG 7 till FIG 11 .
  • the design of the means 3 for illuminating are quite similar compared to the first embodiment explained above.
  • the second blind 19 has a substantial rectangular shape and can be a separate element but also a print on the transparent plate 18.
  • the lamp 5 enters the means for illuminating 3 basically coming from the top in vertical direction. In an alternative solution (not depicted) the lamp 5 enters the means 3 from the side.
  • the blind 19 has a plurality of apertures 20 which are bought into the blind 19 to allow light beaming from the reflector element 4 into the cavity 2.
  • the apertures can have a square form (see aperture 20').
  • they can be formed as an alphabetic character 20" or as a cipher 20"'.
  • the characters or ciphers can easily be read when looking into the cavity as they are illuminated from the reflector element 4.
  • the light from the lamp 5 enters in longitudinal direction into the reflector element 4.
  • the light strikes on the wall elements of the reflector element 4 and thus also on the bow-shaped wall element 13.
  • the light shines from the walls and through the transparent plate 18 (glass) into the cavity 2.
  • the first blind 17 the distribution of the light is improved and blinding is surely prevented.
  • the wall elements of the reflector element 4 can be coated or structured so that an improved distribution of light can be obtained.
  • the lamp 5 is positioned outside the reflector element 4 in the depicted embodiments of the invention it can also be located at one end of the reflector element 3 inside the same.
  • the second blind 19 can be arranged under or on the glass 18. It can be a separate part or can be printed on the glass 18.
  • the blind 17 is not mandatory. In this case the shielding and the support of the distribution of the light can be done by the blind 19.
  • the means for illuminating 3 can be mounted in an opening or recess 26 in the cavity wall 16.
  • the lamp (light source) itself is covered by the reflector element as explained above. Thus, no blinding takes place and the lamp illuminates equally all levels for baking trays all over the vertical direction.
  • the light source can be e. g. a halogen lamp.
  • a concentration element has advantages.
  • the use of a halogen lamp can be taken into consideration which is evaporated at one side.
  • the reflector element can be manufactured e. g. from sheer metal of stainless steel or zinc-plated sheet metal. It can also be made from aluminium or from plastic; in this case the material (aluminium or plastic) can be coated.
  • the housing can be designed in an easier way.
  • the blind can cover the means for illuminating 3 and further improve the blind-free illumination of the cavity. Furthermore, by use of the blind it becomes possible to specifically illuminate desired regions of the cavity.
  • the blind can have alphabetic characters or ciphers. In the case of the blind according to FIG 10 only specific areas are illuminated by the apertures 20. With the solution according to FIG 12 the whole vertical extension can be illuminated.
  • the blind 19 can be covered by a glass plate. But it is also possible that the blind is arranged on a glass plate and has the function of a holding frame.
