Definitions

  • the present invention relates to an operating unit for a refrigerator and/or freezer and a refrigerator and/or freezer with an operating unit.
  • Operating units are known from the prior art, which are arranged in the interior of a refrigerator and/or freezer and thus reduce the volume of the interior and limit the possibilities for arranging fitted shelves, shelves, etc. in the interior.
  • the present invention is based on the object of alleviating the problems of the prior art or even eliminating them entirely.
  • the invention is based on the object of creating an operating unit which impairs the flexibility of the arrangement of shelves, shelves, etc. in the interior as little as possible or not at all.
  • a control unit for a refrigerator and/or freezer having control elements, preferably capacitive, resistive and/or mechanical control elements, and at least one lighting element for partially or completely illuminating an interior of the refrigerator and/or freezer.
  • the functions of illuminating the interior of the refrigerator and/or freezer and operating the refrigerator and/or freezer are preferably integrated in one control unit. This eliminates the need to provide several separate units in the interior and the flexibility of arranging shelves, shelves, etc. in the interior is less affected.
  • the operating unit has at least one sensor system, preferably for detecting temperature, humidity and/or a magnetic field, and at least one output unit, preferably for outputting acoustic and/or optical signals, which are arranged on a common electronic circuit board.
  • the operating unit is arranged in a recess or an opening in a container contour of the refrigerator and/or freezer and is flush with the container contour.
  • the operating unit can be arranged in a recess which was produced by local deep-drawing of the container contour.
  • the container contour can have an opening and the operating unit is arranged on the foam side of the container contour.
  • a refrigerator and/or freezer according to the invention preferably has a control unit according to the invention, which is arranged in a recess or an opening in a container contour of the refrigerator and/or freezer device, with this or its front panel preferably terminating flush with the container contour.
  • a refrigerator and/or freezer according to the invention could have another operating unit which is preferably arranged in a recess or an opening in a container contour of the refrigerator and/or freezer and is flush with the container contour.
  • At least one light source of the operating unit is arranged relative to the container contour in such a way that light from the light source is reflected by the container contour into an interior of the refrigerator and/or freezer. This eliminates the need for a separate reflector and the interior is illuminated indirectly by the light source, preferably through a front panel of the operating unit.
  • the container contour at least partially has a coating to enhance the reflection, in particular a metallic coating.
  • the operating unit is preferably arranged adjacent to a door stop position of a door of the refrigerator and/or freezer and has a magnetic field sensor.
  • the door of the refrigerator and/or freezer preferably has at least one magnet on its end region facing the operating unit, so that the position of the door relative to the refrigerator and/or freezer can be detected based on the interaction of the magnet and the magnetic field sensor. For example, when the door is opened, a lamp on the operating unit can be activated automatically to illuminate the interior.
  • the operating unit is preferably embedded in a container contour, which forms a side wall of an interior space of the refrigerator and/or freezer, and/or in a ceiling of the interior space of the refrigerator and/or freezer.
  • the operating unit preferably has an at least partially transparent or translucent front panel, which forms a continuous or essentially continuous surface with the container contour.
  • FIG. 1 shows, with reference number 1, a schematic refrigerating and/or freezing device according to the invention.
  • the reference symbol I designates the container, i.e. the inner container of the device surrounding the interior.
  • the operating unit 20 is located in this area in the open area that can be closed by a door (not shown).
  • the cone of light emanating from this is denoted by 10 .
  • figure 2 shows in a cross-sectional view with the reference number 30 a storage compartment and with 20 said operating unit.
  • the reference number 40 indicates a magnet arranged on the door, whose presence or movement or approach to the operating unit 20 is detected by the latter, so that, for example, when the door in figure 2 shown door the lighting is switched on.
  • the door stop is identified by 50, around which the door can be pivoted relative to the device body.
  • figure 3 shows a detailed view of the area of the inner container I of the device according to FIG figure 2 .
  • the status display 94 of the light source 90 is also arranged on this, with the light source 90 also being located on the electronic circuit board 70 .
  • Reference number 60 designates the front panel, which delimits the indentations mentioned in the inner container to the cooling or freezer compartment shown on the left and terminates essentially flush with the inner container I.
  • the reflector contour of the inner container I is marked with 80, which has the task of directing the light emanating from the light source 90 in the desired manner into the cooled interior.
  • the depressions are an integral part of the inner container I and can be produced, for example, by deep-drawing.
  • the invention also includes the case in which the operating unit is arranged in a cutout of the inner container and is covered on the foam side, for example by a housing.
