Definitions

  • the invention relates to a household refrigerator with an interior for receiving food, which is limited by walls.
  • the household refrigeration appliance furthermore has a door for closing the interior, and furthermore comprises a lighting device which is designed to illuminate the interior, at least when the door is open.
  • the household refrigerating appliance moreover comprises at least one plate-like compartment divider, which is arranged in the interior and is formed from a light-permeable material.
  • the invention relates to a household refrigerator with an interior for receiving food, which is limited by walls.
  • the household refrigeration appliance further comprises a door for closing the interior, as well as a lighting device, which is designed to illuminate the interior, at least when the door is open.
  • the household refrigerating appliance moreover comprises at least one plate-like compartment divider which is arranged in the interior and is formed at least partially from a light-permeable material. With the compartment divider, the volume of the interior is separated into partial volumes. In particular, it is thus arranged that in vertical direction of the household refrigerator then considered above the compartment divider a partial volume of the interior and below the compartment divider at least a further sub-volume of the interior is formed.
  • the illumination device has a plurality of light sources, which is arranged in a ceiling wall bounding the interior space and oriented so that the interior above and below the compartment divider has a substantially uniform illumination by the emitted light ,
  • the light sources arranged in the ceiling wall to distribute light in the interior such that the partial volumes of the interior formed by the compartment divider are also substantially uniformly illuminated and not only illuminated arbitrarily.
  • the illumination device is thus arranged and designed in particular such that the light emitted by the light sources and thus radiated only from above into the interior light is distributed and directed so that even when viewed in the vertical direction superimposed partial volume of the interior are substantially uniformly illuminated.
  • a substantially identical illumination is understood in particular as one in which, when viewed from the front by a user, a visually very uniform light volume appears, in which no large brightness differences occur, in particular no such local brightness fluctuations appear, which are perceived superficially and eye catching by a user would become.
  • first light sources of the illumination device are arranged such that their emitted light strikes a light coupling region formed in the rear region of the compartment divider formed as a light guide and can be guided in the compartment divider to form a light extraction region is.
  • a compartment divider which is designed in its functionality for the separation and training of partial volume of the interior and represents a floor for applying food at least for a trained sub-volume, used in further functionality for light transmission.
  • the multifunctionality of this compartment divider in particular with regard to its optical use, therefore makes it possible to have a very specific and desired light conduction at specific locations of the interior, so that in this context the illumination is improved.
  • the plate-like compartment divider which usually extends over the width of the interior and thus orientates horizontally, presents itself overall as an optical waveguide.
  • the injected light can be passed very uniformly over the entire width in the optical fiber and coupled out at specific desired locations again, so that here a very uniform light distribution and illumination in specific subvolume of the interior is reached.
  • Due to the relatively large-area configuration of the compartment divider a relatively large-area light guide is formed, so that light can also be coupled in extensively here and light can be coupled out in a circumferential manner to preferably correspondingly large light outcoupling areas. This promotes a very defined and homogeneous light output, whereby a very uniform and extensive illumination of the interior is achieved.
  • the Lichteinkoppel Scheme is formed by at least a portion of a rear edge, in particular by the entire rear edge and thus over the entire length of the rear edge of the compartment divider.
  • a compartment divider loaded with several foods also enables sufficient and extensive illumination of partial volume, since the light of the light sources does not have to be extensive and complicated over the foodstuffs directly can be radiated, but can be used in a rear area of the interior, which is usually then formed very close to the back wall and is usually not covered with food for very unrestricted light conduction and the coupling into the compartment divider as a light guide is not undesirable affected.
  • an area of this part of the rear edge or the surface of the entire edge is formed at an angle other than 90 ° to an upper side and / or a lower side of the compartment divider.
  • Such a chamfer of this rear edge produces a particularly advantageous light coupling region, which permits extensive light coupling, so that a particularly large amount of light can enter the compartment divider and be emitted again at the light outcoupling area, so that here too an improved illumination by the illumination device achieved.
  • this area of this part of the rear edge or the area of the entire edge, which is formed at an angle other than 90 ° to an upper side and / or a lower side of the compartment divider is formed as a flat surface.
  • the latter forms a wedge-shaped or pointed or rearward tapering at the rear area. It then meet in this sectional view two straight lines, the surface and the bottom or the surface and the top, at an angle less than 90 ° to each other.
  • a situation-dependent respectively suitable maximizing light coupling is possible.
  • this area of this part of the rear edge or the area of the entire edge which is at an angle other than 90 ° to a Top and / or an underside of the compartment divider is formed as a curved surface.
  • this surface is at least partially convexly curved, in particular convexly curved over its entire extension between an upper side and an underside of the compartment divider, in particular uniformly convexly curved.
  • the Lichteinkoppel Symposium is spaced from an inner side of a rear wall delimiting the interior space.
  • this promotes the circulation of the cool air prevailing in the interior, so that the best possible and even temperature distribution can be formed.
  • this favors the optical light guidance, since a further passage of light and light radiation is also made possible by this gap between the rear edge of the compartment divider and the inside of the rear wall, which can then reach at least in the subvolume below this compartment divider for illumination.
  • the light extraction area of the compartment divider is formed by a front edge and / or a side edge of the compartment divider.
  • first light sources are thus positioned relatively far back in the interior of the interior.
  • the divider allows. If necessary, complex light deflections in order to be able to radiate light of the first light sources to these light coupling areas are not required.
  • the number of components is reduced and, by means of this very direct light path between the first light sources and the light input region, the highest possible proportion of light can also be coupled in.
  • the first light sources are arranged so that their main emission directions are arranged obliquely forward relative to a vertical rear wall bounding the interior, in particular at an angle between 5 ° and 30 °.
  • the illumination of the interior is favored, and it is also prevented that a relatively large proportion of the emitted light is first illuminated on the rear wall.
  • unwanted local scattering and / or reflection ranges with very high scattering and / or reflection intensity at the rear wall can be avoided.
  • Undesirable points on the rear wall, which are relatively large in area and in their scattering and / or reflection intensity very high compared to other areas, can be avoided.
  • the uniform illumination of the interior is thereby advantageously supported.
  • compartment dividers formed at least partially from a translucent material are arranged at different elevations in the interior and are each formed at the rear edges at least partially with a Lichteinkoppel Scheme.

It may be provided that at least one other compartment divider, which is viewed in the vertical direction below this arranged equal to the rear wall partitions and under the immediately adjacent a front closed drawer box is arranged - compartment divider thus serves practically as a lid for the drawer box - with its rear edge is located at a smaller distance to the rear wall than the other upper compartment divider. As a result, a uniform illumination of the interior can be achieved even with different equipping of the interior with compartment dividers that vary in size and / or in which under the lower compartment divider with the smaller distance is a drawer box. The coupling of the light in all intended coupling areas is then reached.
  • the rear edge of the higher compartment divider is arranged at a first distance to an inner side of a rear wall delimiting the inner space.
  • a rear edge of the lower compartment divider is arranged in a smaller compared to the first distance second distance to the inside of the rear wall.
  • the illumination device preferably comprises at least two second light sources, which are arranged in a front quarter of the depth of the ceiling wall. These second light sources are thus arranged relatively far forward and close to a charging opening for the interior.
  • the lighting scenario for user-friendly observation of food detection in the interior is also positively influenced by this.
  • the second light sources with their dimensions at least partially extend in the direction of the depth extend forward beyond the front edge of the at least one compartment divider. This embodiment is particularly advantageous in that therefore a certain amount of emitted light of the second light sources can also pass down to the upper compartment divider or to the upper compartment divider and the uniform illumination of all partial volumes is also supported here.
  • the second light sources are arranged so that their main radiation directions are arranged obliquely forward relative to a vertical rear wall bounding the interior, in particular at an angle between 5 ° and 30 °.
  • This refinement offers the significant advantage that a region in front of the compartment dividers with a desired amount of light is also illuminated in a targeted and defined manner, so that when the user of the interior observes the door when opened, this also results in a brighter appearance. Due to the specific orientation, this is also achieved virtually across the entire design of the sub-volume when viewed from the front.
  • the household refrigerating appliance has at least one drawer box arranged under the at least one compartment divider, which can be pulled out and retracted in the horizontal direction and can also be equipped with foodstuffs.

  • the emitted light component, which is to reach the partial volume is in this case divided in a desired manner compared to those light components which are to be emitted in front of the compartment dividers and in particular also in the direction of the opened drawer box, so that here too Significant contribution to the uniform illumination of areas to be counted to the interior is possible.
  • the illumination device has at least two first and at least two second light sources which are arranged on the ceiling wall such that when viewed on the ceiling wall plane and thus virtually in a projection view in this ceiling wall plane connecting lines between each two adjacent in a direction of rotation light sources form a trapezoidal shape.
  • the respective light sources connected in the clockwise direction, for example, with the connecting lines then present delimit a surface which has a trapezoidal shape.
  • This positional arrangement also contributes advantageously to the desired uniform illumination scenario.
  • this trapezoidal shape is oriented so that it is positioned closer to the rear side with its shorter base side than with its longer base side.
