Definitions

  • the invention relates to a refrigerator or freezer according to the preamble of claim 1.
  • a pivotable handle is provided as a handle for actuating a door, which releases an airway from the outside into the cooling space enclosed by the device housing and the door when the door is opened via a valve arrangement.
  • the valve arrangement is closed when the handle is not actuated.
  • the air cools down and the elastic seal rests close to the support edge of the device housing, which holds the door in the closed position with considerable force. This vacuum balances itself out when the handle is actuated via the valve arrangement controlled thereby.
  • the invention has for its object to take measures in a refrigerator or freezer according to the preamble of claim 1, through which pressure equalization between the outside atmosphere and the cooling space can be initiated in a simple manner without the use of special valve devices.
  • a section of the seal which is present anyway for the tight seal, is used as a valve path.
  • a simple lifting device that has to be operated manually needs to be assigned to the relevant section.
  • the handle required for this is preferably assigned to a door handle and is actuated together with the latter when the door is opened.
  • the lifting device can be retrofitted to the outside of the door, and the valve does not form any hidden parts, so that good access is possible if icing occurs in this area. If the sealing section is lifted from the support edge of the device housing by the handle, then air can flow freely into the cooling space from outside and bring about pressure equalization.
  • the door opening force is then determined solely by the magnetic strip assigned to the seal, which is usually arranged in the seal and holds the latter in tight contact with the permanent magnetic support edge of the device housing. If the seal has a hollow chamber profile with an expansion fold and is fixed to the door, then the handle need only be provided with an actuating tab that engages behind this expansion fold to lift off the sealing section.
  • a seal (4) with its inserted magnetic strip (5) rests on a support edge (3) that surrounds a cooling chamber (2).
  • the seal (4) is located on a door (6) and has a hollow chamber profile (7) with an expansion fold (8) running in the longitudinal direction of the seal (4).
  • the expansion fold (8) runs parallel to the longitudinal direction of the support edge (3).
  • the hollow chamber profile (7) between the magnetic strip (5) and the supporting inner surface (9) of the door (6) serves to compensate for tolerances in the gap width between the support edge (3) and the inner surface (9) when the door (6) is closed.
  • a fixed handle (10) with an integrally formed foot (11) is attached to the door (6).
  • the door (6) is also assigned a handle (13) which has an actuating tab (14) which, with a single-ended bend (15), engages behind the expansion fold (8) on its flank facing the magnetic strip (5).
  • the handle (13) is by kinking the seal opposite end of the actuating tab (14) is formed, this handle (13) between the user facing front surface of the door (6) and the actual handle (10).
  • the handle (13) thus projects into the engagement opening (12).
  • the handle (13) faces both the front surface of the door (6) or the foot (11) of the handle and on the other hand the handle (10) in a non-actuated position at a distance.
  • the actuating tab (14) can be adjusted between the narrow outer end face (16) of the door (6) and a leg (17) of the foot (11) spanning the same perpendicular to the plane of the support edge (3) or the front of the door (6) guided.
  • the handle (13) can extend as shown over a part, but also about the full clear height of the engagement opening (12).
  • a lever device with the handle (13), which can be attached to the housing (1) and z. B. on a in the support edge (3) recessed lifting device, the seal (4) z. B. partially by means of a displaceable bolt from the support edge when the handle (13) is actuated.
  • the handle only needs to be assigned a displaceable button which, for. B. is pressed when opening the door with the thumb and operated via a linkage, for example, a rocker mounted in the housing, which engages directly with one arm under the seal or adjusts a slide, bolt or the like to the seal and so the seal from the support edge partially takes off.
