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 when the door is opened via a valve arrangement coupled therewith an airway from the outside into the cooling space enclosed by the device housing and the door releases.
  • the valve arrangement is built into the door body and closed when the handle is not actuated.
  • a refrigerator or freezer is also known (US Pat. No. 3,201,883) in which a fixed handle with an engagement opening is rigidly attached to a door.
  • the door is supported by an elastic seal on a support edge of the housing, the seal being Has hollow chamber profile with an inserted magnetic strip, which is connected to a sealing foot via expansion folds.
  • the seal is assigned an automatically acting valve arrangement, which consists of a band that extends from the sealing foot and extends over the hollow chamber profile that receives the magnetic strip and on the opposite side back to the sealing foot. This tape is thus in the sealing joint, so that the seal rests directly on the support edge only in the remaining section.
  • the band lying between the magnetic strip and the support edge of the housing weakens the closing force of the seal with respect to the support edge, so that there is already a risk that in normal operation in this area with negative pressure in the cooling space, outside air will flow in and a ripening process will occur.
  • the length of the tape must be matched very precisely.
  • continuous air channels are formed on the edges of the tape running transversely to the longitudinal direction of the seal, since the tape has a finite thickness and because of its rigidity, the magnetic strip can only press the surrounding sheath against the support edge after a certain distance. Unhindered air exchange takes place particularly through these air channels, which leads to ice and frost layers accumulating in the area in question within the cold room due to the formation of condensation water.
  • the invention has for its object in a cooling or Freezer according to the preamble of claim 1 to take measures by which the formation of condensation water in the area of the valve arrangement is avoided in a manually operable valve arrangement serving for pressure equalization 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.
  • 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 the 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 only needs to 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 associated with 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.
