  • the holding element of the recessed grip can, for example, comprise one or more magnetic or magnetizable sheets or strands which extend along the recessed grip.
  • the magnetic or magnetizable holding elements of the grip element can be covered by a jacket, preferably a plastic sheet. This prevents scratching of the recessed grip.
  • the magnetizable holding element of the recessed grip can be a metal sheet which represents the outer casing of the recessed grip and preferably also other areas of the door. It can be provided that the door has an outer casing which covers a heat insulation layer or other areas of the door. In one embodiment variant, this formwork can extend, for example, over the entire front of the door. If, as in the embodiment described here, the casing is a metal sheet that extends at least also over the area of the recessed grip, the casing itself can serve as a magnetizable holding element of the recessed grip.
  • the outer casing can also be constructed in several parts and, for example, comprise several metal sheets.
  • the device has a further door which closes another area of the interior or a separate interior, the further door also having a recessed grip on at least one side edge on which a magnetic or magnetizable holding element is provided.
  • the handle element can optionally be attached to one or the other door.
  • the other area of the interior or separate interior is also typically cooled using a heat pump, as was described in more detail above.

  • the two doors or at least recessed handles are identical in one, several or all of the aspects described here.
  • the device can be a pure cooling device, a pure freezer or a fridge-freezer combination device. It can also be provided that the temperature of the interior or the temperature of individual zones of the interior can be variably set, so that the device can be operated either as a pure cooling device, a pure freezer or a fridge-freezer combination device.
  • the device according to the invention can be a fridge-freezer combination device and one door closes the cooling area and the other door closes the freezer area.
  • the two-door device can also have a further separate grip element which is detachably inserted into the further grip recess, a magnetic or magnetizable holding element being provided on the further grip element in order to hold the further grip element magnetically in the further grip recess.
  • the holding elements of the further grip element are preferably identical to the holding elements of the first grip element.
  • the two grip elements are identical in one, several or all of the aspects described here.
  • a grip element 10 is shown which can be detachably inserted into the recessed grip of a refrigerator and / or freezer according to the invention.
  • the handle element 10 has a metallic handle bar 11 with a round cross section, which is held in its upper and lower region on a likewise metallic strut 12.
  • the distal end of the struts 12 is connected to a compact foot part 13 made of plastic.
  • the foot parts 13 lie in a line with respect to the direction of the handle bar 11 and both have the same trapezoidal cross section with respect to a plane running normally in this direction. In both foot parts 13 are not shown in the figure because permanent magnets are covered by the plastic of the foot parts.
  • a device 20 according to the invention is shown, which is a fridge-freezer combination device with a cooling compartment and a freezer compartment arranged underneath.
