Definitions

  • the present invention relates to a luminous inner container for a refrigerator and/or freezer as well as a refrigerator and/or freezer with such a container.
  • the object of the present invention is to provide a possibility for shadow-free illumination of an interior space, regardless of the presence of refrigerated goods in the interior space.
  • the object of the present invention is to mitigate or even completely eliminate the problems of the prior art.
  • an inner container for a refrigerator and/or freezer wherein at least one inner wall of the inner container preferably has a translucent and/or light-conducting material over its entire surface and/or consists of a translucent and/or light-conducting material and lamps are also present, by means of which the translucent and/or light-guiding material can be illuminated, preferably over an area or over the entire area.
  • a significant advantage of the present invention is that the viewer gets the impression that the entire inner container is illuminated or the entire inner container acts as a luminous surface.
  • the inner container is formed by panels made of the translucent and/or light-conducting material. As a result, the observer cannot see where the light originates and the light is emitted everywhere and homogeneously by the inner container. This enables optimal illumination of the inner container and prevents the user from being dazzled, as is often the case with point light sources.
  • the inner container is designed in the form of a box and at least two, preferably five, inner walls of the inner container preferably have a translucent and/or light-conducting material over their entire surface and/or consist of a translucent and/or light-conducting material.
  • a particularly nice effect can be achieved if five inner walls of the inner container, for example all inner walls of the inner container except for one inner wall of a door of the refrigerator and/or freezer, have a translucent and/or light-conducting material over their entire surface and/or made of a translucent and/or light-conducting material.
  • all six inner walls, including the door of the refrigerator and/or freezer, can also have a translucent and/or light-conducting material over their entire surface and/or consist of a translucent and/or light-conducting material.
  • a planar or full-area arrangement of the translucent and/or light-conducting material is preferably to be understood here as meaning that the entire or at least almost the entire area of an inner wall is continuously provided or lined with the translucent and/or light-conducting material.
  • the entire surface of the inner container preferably serves to illuminate the interior within the scope of the present invention.
  • Light-conducting material is preferably used if the inner container itself is to be light-conducting.
  • an inner container can be provided according to the invention, which is lined with light guide plates on five inner walls, preferably on the foam side, into which light can be coupled and coupled out at desired locations.
  • the light sources are preferably designed in the form of LEDs and are also designed to couple light into the translucent and/or light-conducting material of the inner container.
  • light is coupled into the light guide plates of the inner container by illuminants (e.g. LEDs) and distributed homogeneously in the light guide plate via total reflection.
  • the lamps or light sources can also be designed as an arrangement of several LEDs, for example as a tunable white or RGB, RGBW or RGBWW LED arrangement, whereby the refrigerator and/or freezer can be equipped with ambient lighting or the interior lighting according to HCL (Human Centric light, ie lighting according to the natural progression of daylight) criteria are implemented.
  • HCL Human Centric light, ie lighting according to the natural progression of daylight
  • the light can be coupled in via edge coupling or areal light coupling using deflection geometries (e.g. rotationally symmetrical cones, aspherical cones, wedges, chamfers, ). Coupling light via light sources embedded/immersed in the material is also conceivable.
  • deflection geometries e.g. rotationally symmetrical cones, aspherical cones, wedges, chamfers, .
  • the total reflected light (in the at least one light guide plate) is decoupled over the surface by decoupling structures (e.g. screen printing, laser engraving, geometries, prisms, holograms, ...), which are distributed over the light guide plate in a specific pattern, so that a homogeneously luminous light guide plate surface.
  • decoupling structures e.g. screen printing, laser engraving, geometries, prisms, holograms, .
  • Translucent material is preferably used if the inner container should be able to be transilluminated by a light source.
  • an inner container can be provided according to the invention, which is made of a translucent material, for example a polymer material, on five inner walls, which is backlit and transilluminated by means of a preferably flat light source, in particular an OLED film, or one or more light guide plates.
  • the lighting means are preferably designed in the form of OLEDs and are also designed to shine through the translucent and/or light-conducting material of the inner container, preferably over an area or over the whole area.
  • a preferably flat OLED arrangement is provided, by means of which the translucent inner container can be backlit or transilluminated. It is also conceivable to laminate or glue an OLED film directly onto the inner container, which then backlights the translucent inner container.
  • An advantage of this lighting system is that the inner container in this embodiment can be carried out completely without gaps and joints and does not require openings for the lighting system, which means that it is completely shielded.
  • the illuminants also referred to as light sources
  • the light guide plates are arranged on the inner container on the foam side, i.e. arranged between a layer delimiting the inner container to an interior space formed by it and a foam layer.
  • At least one inner wall of the inner container is formed by light guide plates which are spaced apart from an interior space formed by the inner container by a layer of a translucent material.
  • the thin layer of translucent material shields the light guide plates from the interior and thus protects them from damage such as scratching.
  • At least one light-coupling structure is preferably provided, by means of which light can be coupled into the translucent and/or light-guiding material of the inner container, with the at least one light-coupling structure for edge coupling, areal light coupling or for coupling via deflection geometries, in particular in the form of cones, wedges or chamfers.
  • the light can be coupled in via light sources embedded or immersed in the light-guiding material.
  • At least one light extraction structure is preferably provided, which preferably has a screen print, a laser engraving, an extraction geometry, a prism or a hologram and which is designed in such a way that light is emitted homogeneously and preferably flat or over the entire surface from the translucent and / or light-guiding material can be coupled out.
  • a plurality of light decoupling structures are preferably provided, which are distributed homogeneously over the inner wall or inner walls of the inner container that are equipped with the light-conducting material.
  • the inner container itself can be used as a light guide and the light can be coupled directly into the inner container.
  • a plastic circuit board which is used, for example, in the production of an inner container according to the invention as the starting material before deep-drawing, can be, for example, a 2-component circuit board, having or consisting of a transparent plastic as the base material and a translucent/milky white layer laminated thereon, which later on the inside in the container is.
  • an inner container according to the invention can be manufactured in one piece, preferably by means of deep drawing or injection molding.
  • a plastic blank can be used as the starting material before deep-drawing, for example, which has a transparent plastic as the base material and a layer of a translucent or milky white material connected and/or laminated to it, which is later arranged on the inside of the inner container, which prevents a User sees the foam layer of the inner container.
  • Another aspect of the invention relates to the use of an inner container according to the invention with a refrigerator and/or freezer.
  • the invention relates to a refrigerator and/or freezer with an inner container according to the invention.
  • such a refrigerator and/or freezer can have a box-like or crate-shaped vacuum panel, in which first the lighting unit with one or more light guide plates (preferably light guide plates on five walls of the vacuum panel) is installed and finally a translucent inner container is installed.
  • the lighting unit with one or more light guide plates preferably light guide plates on five walls of the vacuum panel
  • an inner container according to the invention used as a light guide to be installed directly in a box-like or crate-shaped vacuum panel of a refrigerator and/or freezer.
  • FIG. 1 a front view of a box-like arrangement of several light guide plates 1, which can form either an inner container or a lining for an inner container.
  • light is coupled directly into the light guide plates 1 and coupled out of them at a desired point by means of coupling structures 2 .
  • the decoupling structures 2 are arranged homogeneously on the light guide plates 1 .
  • five sides of the box-like structure top, bottom, side walls, rear wall) are formed by circuit boards 1.
  • the illuminants or light sources which are designed as LEDs 3 in this embodiment, can also be seen.
  • LED bars are present, which extend along the edges of the box-like arrangement and introduce light into the light guide plates 1 .
  • FIG. 12 shows a rear view of the embodiment of FIG 3 .
  • FIG. 12 shows a view of an embodiment of the invention in practice.
  • the inner container 4 shines brightly throughout and without a recognizable punctiform light source, which leads to a diffuse and therefore glare-free illumination of the interior.
