Definitions

  • the present invention relates to a refrigerator and / or freezer according to the preamble of claim 1.
  • a device is for example from the DE-U1-20 2005 014 370 known.
  • the lighting unit is generally located in the interior of the device and is activated when the door or flap of the device is opened.
  • hinged lights that are switched on and swung when opening and closing the door.
  • the object of the present invention is therefore to develop a refrigerator and / or freezer of the type mentioned in such a way that the lighting is designed to be efficient and less susceptible to interference.
  • This combination can be used according to the invention both in devices that have a control in the interior, as well as in devices that have an operating or control unit outside the interior.
  • the advantages of an assembly of lighting means and evaporator module include cost advantages through easier installation and lower variety of parts and a lesser design effort of the complete assembly.
  • lighting means includes any luminous bodies, such as light bulbs and in particular also LEDs.
  • the illumination means are formed by one or more LEDs or comprise one or more LEDs.
  • LEDs are thus used for illumination, the u. a. have the advantage that they are small and therefore can be used in confined spaces, as LEDs have a relatively low heat generation. By using one or more LEDs, it is thus also possible to arrange the lighting in very tight spaces.
  • control and / or control unit can be arranged inside or outside the device. It is conceivable, for example, to form the operating and / or control unit above the refrigerated appliance interior in the form of a front strip.
  • the operating and / or control unit is arranged above the refrigerated device interior. It may, for example, be arranged in an area which is covered by the door when it is closed.
  • the evaporator module has a diaphragm with a recess and that the illumination means are arranged such that they emit light through the recess.
  • the illumination means are located on the underside or front side of the evaporator module and are arranged to pass through a recess in the bottom or front side of the evaporator module emit light.
  • the evaporator module is arranged in an upper region of the device, for example at eye level, and the illumination is provided such that it emits light when the door of the device is open at the bottom and / or at the front.
  • the evaporator module has a diaphragm which forms at least the front cover of the evaporator module. It is conceivable that the illumination means are arranged in or on the diaphragm. The recess through which the light is emitted is arranged in the diaphragm.
  • the illumination means or a lighting unit comprising the illumination means is flush with the panel or protruding from the latter.
  • the lighting can thus be performed unobtrusively, flush or for example slightly protruding.
  • embodiments in very tight spaces are possible by the preferred use of one or more LED lighting.
  • the illumination is provided by two or more than two luminous bodies, which are arranged such that they emit light in different directions. Due to different angles of the light, it is possible to bring light effects precisely focused with depth effect, for example on drawers or, for example, in the interior of the device.
  • the diaphragm of transparent material consists. It can thus be used a transparent material for the panel be, which has the advantage that any cover of the lighting unit and the aforementioned aperture can be made of one part. It can be provided that areas of the diaphragm, which should not be transparent, are covered by printing, painting or in an injection process via the in-mold process.
  • the inventive arrangement of lighting means on the evaporator module has the advantage that certain lighting effects can be generated.
  • certain lighting effects can be generated.
  • backlighting This can be done for example by exploiting stray light of said lighting or by a targeted backlighting, for example by attaching light guides, which emanate from the lighting means.
  • the illumination means are connected to an electrical assembly which controls or supplies at least one further component in addition to the supply of the illumination means.
  • the lighting means such as the LEDs, which are needed for lighting, can on an existing board of the module, such. B. the control panel board are integrated. A separate board for lighting is therefore not required. This creates a cost-effective unit through the use of an existing board plus lighting. It is also possible to fall back on existing standard modules in the lighting in the operating or control unit or in the evaporator module. These may be, for example, standardized components or lighting assemblies already used in other devices, in particular LED lighting assemblies.
  • the evaporator module of the refrigerator and / or freezer according to the invention is located in an upper region of the interior, ie immediately below the ceiling of the inner container and thus forms the upper end of the interior of the refrigerator and / or freezer.
  • LEDs have the advantage that they are small and have a comparatively low heat output, so that they can be used effectively even in confined spaces. Another advantage is that by means of LEDs targeted light can be focused in certain areas, such as in drawers, which are preferably to be illuminated.
  • FIG. 1 shows by the reference numeral 10 an operating and / or control unit of a freezer according to the invention.
  • the control and / or control unit 10 is located at the height of the upper end portion of the door and is dimensioned so that it is not visible when the door is closed, but by the upper end portion the door is hidden.
  • the control and / or control unit is arranged such that it is located above the closed door, that is accessible when the door is closed.
  • the operating and / or control unit 10 has an aperture which forms the front side, the underside and the upper side of the operating and / or control unit 10.
  • LEDs running bulbs are located in the panel or in the control and / or control unit 10 as LEDs running bulbs.
  • the LEDs are arranged such that they emit light down through the located in the bottom of the aperture recess 20 and thus the interior of the refrigerator and / or freezer and from the user's point of view in front of the interior area, in particular the interior illuminated drawers or solid floors, as this particular FIG. 2 evident.
  • FIG. 3 an embodiment of the present invention is shown in which in the evaporator module 30, which is located at the top in the inner container of the freezer, arranged with one or more LEDs lighting unit is arranged, by means of which light is emitted down and possibly forward. Also in this way it is possible to illuminate the interior of the refrigerator or freezer and possibly the area located in front of this.
  • the illumination is arranged in the evaporator module 30 on its underside, so that the light is emitted predominantly downwards.
  • the illumination means of the refrigerator and / or freezer according to the invention can be made movable such that the illuminated area can be changed by the user, so that particularly preferred areas of the device can be illuminated.
